Material belt cutting clamp

Technical Field

The present invention relates to a tape cutting jig for cutting a component supply tape used in a tape feeder.

Background

A component mounting apparatus including a tape feeder for supplying components using a tape as a carrier is known. The component supply tape (hereinafter referred to as a component tape) includes a carrier tape in which a plurality of component storage sections are formed, and a cover tape attached to the carrier tape so as to cover the component storage sections. The component tape is set on the tape feeder in a state of being wound on a reel. The tape feeder pulls the component tape out of the reel and unseals the component tape immediately before the component take-out position, specifically, peels off or cuts the cover tape so that the component can be taken out.

For example, patent document 1 discloses a tape feeder for unsealing a component tape by cutting a cover tape with a cutter. The tape feeder is a so-called splice-free tape feeder of the following type: the distal end of the subsequent component tape (subsequent tape) is set in advance at a prescribed position, and the subsequent tape is automatically loaded after the component of the preceding component tape (preceding tape) is used up.

In this tape feeder, a cutter must be inserted between the carrier tape and the cover tape at the distal end of the tape each time loading of the subsequent tape is performed. Therefore, in order to smoothly and reliably perform the insertion of the cutter, it is necessary to appropriately process the distal end of the component tape. Specifically, the following processing jobs are required: 1) cutting the component tape at a location between adjacent component pockets and using the cut location as a distal end of the component tape; 2) the distal end of the element strip is shaped (flexed) into a shape suitable for insertion of a tool.

The handling of such component tape at the distal end is cumbersome. For this reason, for example, a tape cutting jig disclosed in patent document 2 has been proposed. The tape cutting jig has a stapler-type structure having an upper portion and a lower portion which are connected to each other so as to be openable and closable, and performs the operations 1) and 2) described above simultaneously with the component tape positioned and sandwiched between the upper portion and the lower portion. According to this tape cutting jig, the above-described processing operation can be easily performed.

However, in the case of using the stapler-type tape cutting jig as in patent document 2, the component tape can be positioned, but the cutting position of the component tape cannot be visually recognized, and therefore, it is difficult for the operator to see whether or not the component tape is cut correctly. Further, since the operator must hold the entire jig with the palm of the hand to use the jig, it is difficult to increase the size of the jig in consideration of the ease of handling the jig. That is, if the jig is enlarged, it is difficult for the operator to hold the jig and to perform the operation. Therefore, such a jig is not suitable for a case where, for example, a wide component tape is targeted. Therefore, there is room for improvement in this point.

Detailed Description

Fig. 1 is a perspective view of a tape cutting jig 10 according to a first embodiment of the present invention. The tape cutting jig 10 is a jig for performing a predetermined processing in advance on a tape 1 (hereinafter referred to as a component tape 1) for supplying components to be used on a tape feeder mounted on a component mounting apparatus other than the tape feeder. Specifically, the tape cutting jig 10 is a jig for cutting the component tape 1 and molding the distal end portion of the cut component tape 1 into a predetermined shape.

[ description of the component tape 1 ]

Fig. 2A is a plan view of the component tape 1, and fig. 2B is a sectional view of the component tape 1 (which is a sectional view taken along line IIB-IIB of fig. 2A).

The component tape 1 is a tape-shaped component tape in which components are housed at predetermined intervals in the longitudinal direction, and is set on a tape feeder in a state of being wound on a reel. The component tape 1 is composed of a carrier tape 2 and a cover tape 3.

In the carrier tape 2, a plurality of component housing portions 2a are formed at predetermined intervals in the longitudinal direction. Each element housing portion 2a houses an element (not shown). Further, the carrier tape 2 has a plurality of feed holes 2b formed at a predetermined interval (arrangement pitch P) in the longitudinal direction on one end side (upper side in fig. 2A) in the width direction (direction orthogonal to the longitudinal direction). The feed hole 2b is a hole which is engaged by a sprocket for tape feeding when the component tape 1 is set on the tape feeder. The element housing portion 2a is formed in a fixed positional relationship with the feed holes 2 b.

The cover tape 3 is attached to the upper surface of the carrier tape 2 so as to cover the component accommodation portion 2 a. The cover tape 3 is formed of a transparent resin film, and both ends in the width direction thereof are attached to the carrier tape 2.

The carrier tape 2 is made of a material having flexibility such as paper or resin. The specific material is determined according to the size, application, cost, and the like of the element to be housed, and in the case of paper, for example, as shown in fig. 2B, the bottom surface is not provided with irregularities and has a predetermined thickness as a whole, and in the case of resin, for example, as shown in fig. 2C, the portion corresponding to the element housing portion 2a is subjected to a bulging process so as to protrude toward the bottom surface side. In the following description, the component tape 1 shown in fig. 2B will be referred to as "first type tape 1A" and the component tape 1 shown in fig. 2C will be referred to as "second type tape 1B", respectively.

Although not described in detail, the tape feeder is a so-called splice-less tape feeder having a structure in which the cover tape 3 is cut by a cutter to open the component tape 1. Specifically, as shown in fig. 3, the component tape 1 is unsealed by cutting the widthwise central portion of the cover tape 3 in the longitudinal direction and spreading the cover tape to both sides. In such a tape feeder, when the component tape 1 is loaded, the cutter not shown is inserted between the carrier tape 2 and the cover tape 3 at the distal end portion 1a of the component tape 1. Therefore, in order to smoothly and reliably insert the cutter, it is preferable that the distal end portion 1a of the element tape 1 is processed in advance. Specifically, it is preferable that: 1) cutting the component tape 1 linearly in a direction orthogonal to the longitudinal direction at a position between the adjacent component housing portions 2A (position of symbol Cu in fig. 2A), the cut position being a distal end of the component tape 1; 2) the distal end portion of the element tape 1 is formed into a prescribed shape. The tape cutting jig 10 is a jig for performing such a preliminary processing on the component tape 1.

In fig. 2A, the cutting position (position indicated by reference numeral Cu) of the component tape 1 is at the middle of the adjacent component housing portions 2A, but the ideal cutting position is not necessarily limited to the middle, and may be a position deviated from the middle.

[ Structure of Material Belt cutting jig 10 ]

As shown in fig. 1, the tape cutting jig 10 includes: a clamp body 12; a table 14 for holding the component tape 1; two distal end holding portions 16A, 16B rotatably supported by the table 14; a pressing member 17 that presses (presses) the distal end gripping portions 16A, 16B; a tape fixing member 18 for fixing the component tape 1 to the table 14.

The jig main body 12 has a scissors-type structure including: a first member 20 having a first blade 20a at one end (distal end) and a first grip 20b at the other end (rear end); a second member 21 having a second blade 21a at one end (distal end) and a second grip 21b at the other end (rear end); the pivot shaft 23 pivotally connects the first member 20 and the second member 21 to each other to be rotatable. Each of the first blade portion 20a and the second blade portion 21a is a straight blade having a blade line extending linearly. The jig main body 12 cuts the component tape 1 sandwiched between the first blade portion 20a and the second blade portion 21a by receiving an operation (referred to as a cutting operation) of grasping and gripping the first grip portion 20b and the second grip portion 21 b. Although not shown in fig. 1, a spring member that applies a biasing force in a direction away from each other, that is, in a direction in which the first blade portion 20a and the second blade portion 21a are spread (a direction in which the jig main body 12 is brought into the blade-open state) as shown in fig. 1, may be provided between the first grip portion 20b and the second grip portion 21 b.

In the following description of the tape cutting jig 10, the axial direction of the pivot shaft 23 is referred to as the "width direction" and the direction in which the edge line of the first blade section 20a extends is referred to as the "front-rear direction" as shown in fig. 1, except for the case where it is specifically mentioned. The side of the first blade 20a (second blade 21a) is referred to as "front side", and the side of the first grip 20b (second grip 21b) is referred to as "rear side".

The table 14 is disposed on the side of the first blade 20a of the jig main body 12. Specifically, as shown in fig. 4, the first blade 20a is located on the left side of the second blade 21 a. The table 14 is disposed on the left side of the first blade 20a, that is, on the opposite side of the second blade 21a with the first blade 20a therebetween.

The table 14 is a flat metal block member having a substantially flat upper surface 14a (corresponding to the "tape holding surface" of the present invention) and a rectangular shape in plan view. In this example, one table 14 is constituted by two block members arranged in tandem and having a substantially rectangular shape in a plan view. The table 14 is provided such that the upper surface 14a thereof is parallel to a plane defined by the front-rear direction and the width direction and is positioned to be slightly lower than the edge line, specifically, to be slightly lower than the thickness component of the component tape 1. The table 14 is fixed to the first member 20 by the bracket 15, and is rotatable integrally with the first blade 20a about the pivot shaft 23 as a fulcrum.

The upper surface 14a of the table 14 is provided with two front and rear tape holders 30, 31 (a first tape holder 30 and a second tape holder 31) and two front and rear distal support portions 40A, 40B (a first type tape distal support portion 40A and a second type tape distal support portion 40B).

The tape holding portions 30 and 31 are portions that hold the component tape 1 in a state where the component tape 1 is able to be linearly cut in a direction orthogonal to the longitudinal direction thereof (i.e., in a crossed state) at a position between adjacent component accommodation portions 2a of the component tape 1 in a state where the component tape 1 crosses the first blade portion 20a and the second blade portion 21a of the jig main body 12 in the width direction.

The first tape holding portion 30 is located on the rear side with respect to the front-rear direction center portion of the table 14, and the second tape holding portion 31 is located on the front side with respect to the front-rear direction center portion of the table 14.

The first tape holding portion 30 is a portion that holds the component tape 1 when the component tape 1 is cut. Further, in the case where the component tape 1 is the first type tape 1A, it is a portion that holds the component tape 1 when the component tape 1 is cut and the distal end portion 1A thereof is molded into a prescribed shape. The second tape holding section 31 is a portion that holds the second type tape 1B when the distal end portion 1a of the component tape 1 is molded into a prescribed shape in the case where the component tape 1 is the second type tape 1B.

The first tape holder 30 is located entirely within the range of the first blade 20a, and the second tape holder 31 projects forward from the distal end of the first blade 20a in most parts.

The first tape holder 30 includes a first pitch holder 32 and a second pitch holder 33 arranged in tandem. These holding portions 32 and 33 are portions for holding the component tape 1 having different arrangement pitches P of the component housing portions 2 a. Specifically, the first pitch holding portion 32 is located on the rear side and is a portion for holding the component tape 1 in which the component housing portions 2a are arranged at a pitch of 2 mm. The second pitch holding portion 33 is located on the front side and is a portion for holding the component tape 1 in which the component housing portions 2a are arranged at a pitch of 4 mm.

The first pitch holding portion 32 is provided with a pitch indicator 36a and a pair of positioning pins 37a and 37a arranged in the width direction, and similarly, the second pitch holding portion 33 is provided with a pitch indicator 36b and a pair of positioning pins 37b and 37b arranged in the width direction.

The pitch marks 36a, 36b are marks indicating the kind of the component tape 1. In the illustrated example, the first pitch holding portion 32 is provided with a mark "P2" indicating that the element housing portions 2a are arranged at a pitch of 2mm, and the second pitch holding portion 33 is provided with a mark "P4" indicating that the element housing portions 2a are arranged at a pitch of 4 mm. In this example, the component tape 1 having a pitch of 2mm corresponds to the "first tape" of the present invention, and the component tape 1 having a pitch of 4mm corresponds to the "second tape" of the present invention.

The positioning pins 37a, 37a and the positioning pins 37b, 37b are pins for positioning the component tape 1, respectively. The intervals of the positioning pins 37a, 37a are the same as those of the positioning pins 37b, and these intervals are each equal to a multiple of an integer of the interval D (refer to fig. 2A) of the feeding holes 2b of the component tape 1. That is, in the first pitch holding portion 32, the component tape 1 is positioned based on the insertion of the positioning pins 37a and 37a into the two feed holes 2b, and in the second pitch holding portion 33, the component tape 1 is positioned based on the insertion of the positioning pins 37b and 37b into the two feed holes 2 b. Thereby, the element tape 1 can be held at a predetermined position with respect to the blade portions 20a, 21a of the jig main body 12 in each of the first pitch holding portion 32 and the second pitch holding portion 33. Thus, by holding the component tape 1 in the tape holding sections 32 and 33 so as to intersect the blade sections 20a and 21a and performing the cutting operation, the component tape 1 can be repeatedly and accurately cut at a predetermined position without depending on the operator.

The positions of the positioning pins 37a and 37a of the first pitch holding portion 32 and the positions of the positioning pins 37b and 37b of the second pitch holding portion 33 are set so that the position between the adjacent element housing portions 2A of the element tape 1 held by the holding portions 32 and 33 (the position indicated by the symbol Cu in fig. 2A) is exactly positioned at the position where the tape cutting is performed by the jig main body 12 (the first blade portion 20a and the second blade portion 21 a).

The second tape holding portion 31 also includes a first pitch holding portion 34 and a second pitch holding portion 35 arranged in tandem in the same manner as the first tape holding portion 30. The first pitch holding portion 34 is located on the rear side, and the second pitch holding portion 35 is located on the front side.

The first pitch holding portion 34 has a configuration equivalent to the first pitch holding portion 32 of the first tape holding portion 30, and the second pitch holding portion 35 has a configuration equivalent to the second pitch holding portion 33 of the first tape holding portion 30. That is, the first pitch holding portion 34 is provided with a pitch index 36c and a pair of positioning pins 37c and 37c, and the second pitch holding portion 35 is provided with a pitch index 36d and a pair of positioning pins 37d and 37 d.

The positions of the positioning pins 37c, 37c of the first pitch holding portion 34 and the positions of the positioning pins 37d, 37d of the second pitch holding portion 35 are set so that the distal end portion 1a of the cut component tape 1 (second-type tape 1B) can be arranged on the second-type tape distal end support portion 40B when the component tape is held by these holding portions 34, 35. The positions of the pitch marks 36c, 36d and the positioning pins 37c, 37d of the second tape holding portion 31 (the first pitch holding portion 34, the second pitch holding portion 35) are offset by a predetermined dimension to the left with respect to the positions of the pitch marks 36a, 36b and the positioning pins 37a, 37b of the first tape holding portion 30 (the first pitch holding portion 32, the second pitch holding portion 33).

The two distal end support portions 40A, 40B (the first type tape distal end support portion 40A, the second type tape distal end support portion 40B) support the distal end portion 1a of the component tape 1 cut by the jig main body 12 (the first blade portion 20A and the second blade portion 21a), and form the distal end portion 1a into a prescribed shape together with the two distal end holding portions 16A, 16B. In detail, the first-type tape distal end support portion 40A is a portion for molding the distal end portion 1A of the first-type tape 1A, and the second-type tape distal end support portion 40B is a portion for molding the distal end portion 1A of the second-type tape 1B.

The distal end support portions 40A and 40B are provided integrally with the table 14 at the right end of the table 14. Specifically, the first-type tape distal end support portion 40A is located at the right end of the first tape holding portion 30, and the second-type tape distal end support portion 40B is located at the right end of the second tape holding portion 31.

The first-type-tape distal end support portion 40A has a molding portion 41 for molding the distal end portion 1A of the component tape 1 into a prescribed shape in the case where the component tape 1 is the first-type tape 1A. As shown in fig. 4, 6, and 9B, the molding portion 41 includes an inclined surface 14B provided at the right end of the upper surface 14a and extending obliquely upward to the right, and a portion of the upper surface 14a other than the inclined surface 14B and adjacent to the inclined surface 14B. As shown in fig. 4, the molding portion 41 extends in the range of the region of the table 14 corresponding to the first tape holding portion 30 in the front-rear direction, that is, in the direction orthogonal to the longitudinal direction of the component tape 1 held by the first tape holding portion 30.

The second-type tape distal end support portion 40B has a molding portion 42 for molding the distal end portion 1a of the component tape 1 into a prescribed shape in the case where the component tape 1 is the second-type tape 1B. The molding portion 42 is composed of an upper surface 14a of the table 14 and two groove-like recesses 14c provided at right ends of the upper surface 14 a. The concave portions 14c have a substantially semicircular cross-sectional shape, and extend in parallel to each other from the right end of the table 14 to the left side. The concave portions 14c are provided at positions corresponding to the holding portions 34 and 35 of the second tape holding portion 31. Specifically, the rear concave portion 14c is provided at a position corresponding to the center in the width direction of the element receiving portion 2a of the second type tape 1B held by the first pitch holding portion 34, and the front concave portion 14c is provided at a position corresponding to the center in the width direction of the element receiving portion 2a of the second type tape 1B held by the second pitch holding portion 35.

The tape fixing unit 18 is a member for fixing the component tape 1 to the table 14 at the time of cutting the component tape 1, and is detachably provided on the upper surface 14a of the table 14 as shown in fig. 1, 5, and 7. The tape fastener 18 is connected to the table 14 by a flexible string 44, and hangs down below the table 14 by the string 44 except when used (see fig. 1). In fig. 5, the string 44 is not shown (the string 44 is also basically not shown in other drawings).

As shown in fig. 5 and 7, the tape fixing member 18 is a metal block member in a rectangular parallelepiped shape, and includes a through hole 18a at one end in the longitudinal direction. On the other hand, as shown in fig. 1 and 4, a fixing pin 46a, a pair of regulating pins 46b, and a magnet 47 are provided on the upper surface 14a of the table 14. A pair of regulating pins 46b, 46b are provided upright at the rear end portion of the upper surface 14a at a predetermined interval in the width direction, and a fixing pin 46a is provided upright at the center portion of the upper surface 14 a.

The tape fixing member 18 is located between the two restricting pins 46b, and is provided at the first tape holding portion 30 of the upper surface 14a based on the insertion of the fixing pin 46a into the through hole 18 a.

As shown in fig. 4, the tape fixing member 18 thus provided is in a state of crossing the first pitch holding portion 32 and the second pitch holding portion 33 in the front-rear direction, more specifically, in a state of crossing between the pair of positioning pins 37a, 37a and between the pair of positioning pins 37b, 37 b. In this state, the tape fixing member 18 is restricted in the front, rear, left, and right directions by the restricting pins 46b, 46b and the fixing pin 46a, and is held by the upper surface 14a (the first tape holding portion 30) by the magnetic force of the magnet 47 buried in the upper surface 14a at a position between the restricting pins 46b, 46 b.

The tape fastener 18 includes two notches 19a and 19b aligned in the longitudinal direction. These notch portions 19a and 19b form a space that penetrates in the width direction between the upper surface 14a and the tape holder 18 in a state where the tape holder 18 is provided on the first tape holder 30. The rear notch 19a is located between the positioning pins 37a, 37a of the first pitch holding portion 32 and the positioning pins 37b, 37b of the second pitch holding portion 33, and the front notch 19b is located in front of the positioning pins 37b, 37b of the second pitch holding portion 33. As described later, these notch portions 19a and 19B are portions for receiving the protruding portions corresponding to the component receiving portions 2a when the second type tape 1B is set in the first tape holding portion 30 in an inverted posture.

The pair of distal end gripping portions 16A and 16B (the first type tape distal end gripping portion 16A and the second type tape distal end gripping portion 16B) are portions that grip the distal end portion 1a of the component tape 1 cut by the clip main body 12 together with the distal end support portions 40A and 40B in order to mold the distal end portion 1a into a predetermined shape.

The first-type-tape distal end holding portion 16A is a portion that holds the distal end portion 1A of the component tape 1 together with the molding portion 41 of the first-type-tape distal end support portion 40A in the case where the component tape 1 is the first-type tape 1A. As shown in fig. 1, the first type tape distal end holding portion 16A has an L-shape including an arm portion 50a extending along the rear end surface of the table 14 and a forming portion 51a extending forward in the front-rear direction from the distal end of the arm portion 50 a. The forming portion 51a is a portion that grips the distal end portion 1a of the element tape 1.

The base end of the arm 50a is rotatably supported by the rear end surface of the table 14 via a pivot 52a extending in the front-rear direction. Thereby, the first-type web distal end gripping portion 16A is rotatably supported by the table 14. Specifically, as shown in fig. 6, the first-type-tape distal-end holding portion 16A is displaceable in a range between a molding position P1 (a position shown by a chain line) at which the molding portion 51a holds the distal end portion 1a of the component tape 1 together with the first-type-tape distal-end supporting portion 40A, and a predetermined retreat position P0 (a position shown by a two-dot chain line) at which the molding portion 51a retreats from the molding position P1 and releases the distal end portion 1a of the component tape 1.

The molding portion 51a includes a flat reference surface 53a (see fig. 11B) facing a portion of the molding portion 41 of the first-type tape distal end support portion 40A other than the inclined surface 14B in a state where the first-type tape distal end holding portion 16A is disposed at the molding position P1, and an inclined surface 53B (see fig. 11B) facing the inclined surface 14B. The reference surface 53a and the inclined surface 53b each extend in parallel with the pivot shaft 52 a. According to this configuration, the first-type-tape distal end holding portion 16A (the molding portion 51a) and the first-type-tape distal end supporting portion 40A (the molding portion 41) hold the distal end portion 1a of the component tape 1 supported by the first tape holding portion 30 and mold the portion into an upwardly bent shape (see fig. 11B).

As described above, the pivot shaft 52a is a shaft extending in the front-rear direction. That is, the pivot shaft 52a is an axis extending in a direction (a direction parallel to the edge line of the first blade portion 20a) parallel to the upper surface 14a of the table 14 in a direction (a direction perpendicular to the pivot shaft 23) perpendicular to the longitudinal direction of the component tape 1 supported by the first tape holding portion 30. As described above, the molding portion 41 (the upper surface 14a and the inclined surface 14b) of the first-type tape distal end support portion 40A extends in the front-rear direction, and the molding portion 51a (the reference surface 53a and the inclined surface 53b) also extends in the front-rear direction. Therefore, the molding portion 51a is displaced (rotated) around the pivot shaft 52a in a state where the longitudinal direction (front-rear direction) of the molding portion 51a is kept equal to the distance relationship between the molding portion 51a and the molding portion 41 of the first-type-tape distal-end support portion 40A.

In addition, a restricting member 56 formed of a plunger is provided at a corner portion of the first-type-material-tape distal end holding portion 16A, that is, a portion between the arm portion 50a and the molding portion 51 a. The regulating member 56 regulates the displacement of the first-type tape distal end gripper 16A, as indicated by the solid line in fig. 6, and is a member that holds the first-type tape distal end gripper 16A at a specified temporary position P2 between the molding position P1 and the retracted position P0. The temporary position P2 is a position before the component tape 1 supported by the first tape holding portion 30 is sandwiched between the molding portions 41 and 51a, and a gap is formed between the molding portion 51a and the component tape 1.

The restricting member 56 (plunger) is constituted by a cylinder portion 57a fixed to the first-type-web distal end gripping portion 16A, a pin portion 57b held by the cylinder portion 57a so as to be movable in and out, and a spring member (not shown) that is built into the cylinder portion 57a and applies a biasing force in a direction in which the pin portion 57b protrudes. The restricting member 56 abuts against the table 14 while the first-type tape distal end gripper 16A is displaced from the retracted position P0 to the molding position P1, thereby holding the first-type tape distal end gripper 16A at the temporary position P2. Further, when the first-type tape distal end holding portion 16A is pressed (depressed) from above at this temporary position P2, the pin portion 57b enters the cylinder portion 57a against the urging force of the spring member built in the restriction member 56, thereby allowing the first-type tape distal end holding portion 16A to be displaced from the temporary position P2 to the molding position P1.

On the other hand, the second-type tape distal end holding portion 16B is a portion that holds the distal end portion 1a of the second-type tape 1B together with the second-type tape distal end support portion 40B when the component tape 1 is the second-type tape 1B.

As shown in fig. 1, the second type distal end holding portion 16B has an L-shape including an arm portion 50B extending along the front end surface of the table 14 and a forming portion 51B extending rearward in the front-rear direction from the distal end of the arm portion 50B. The second-type distal nip portion 16B has a basic structure common to the first-type distal nip portion 16A except that the shape of the molding portion 51B is different from that of the molding portion 51a of the first-type distal nip portion 16A. Therefore, the difference from the first-type distal holding portion 16A will be mainly described in detail, and the other structures will be omitted or briefly described.

The arm portion 50B of the second-type tape distal end holding portion 16B is rotatably supported by the front end surface of the table 14 via a pivot 52B. Thus, the second-type tape distal end holding portion 16B can be displaced in a range between the molding position P1 at the time when the molding portion 51B holds the distal end portion 1a of the component tape 1 together with the second-type tape distal end support portion 40B and the retracted position P0 after the molding portion 51B is retracted from the molding position P1 and releases the distal end portion 1a of the component tape 1. Further, the restricting member 56 formed of a plunger is provided also at the corner of the second type tape distal end gripper 16B in the same manner as the first type tape distal end gripper 16A, whereby the second type tape distal end gripper 16B can be held at the predetermined temporary position P2 between the molding position P1 and the retracted position P0.

The molding portion 51B includes a flat reference surface 54a (see fig. 14B) facing the upper surface 14a of the table 14 in a state where the second-type tape distal end holding portion 16B is disposed at the molding position P1, and two convex portions 54B (see fig. 14B) corresponding to the two concave portions 42 of the second-type tape distal end supporting portion 40B, respectively. The reference surface 54a extends parallel to the pivot shaft 52 b. The convex portion 54b has a substantially semicircular cross-sectional shape corresponding to the concave portion 42. That is, the second-type tape distal end holding portion 16B (the molding portion 51B) and the second-type tape distal end supporting portion 40B (the molding portion 42) hold the distal end portion 1a of the component tape 1 supported by the second tape holding portion 31, more specifically, hold only the portion located on the distal end side with respect to the leading component accommodating portion 2a, and thereby mold an arc-shaped curved portion extending in the longitudinal direction of the component tape 1 at a position corresponding to the widthwise center of the component accommodating portion 2 a.

The first tape holding portion 30, the first-type tape distal end supporting portion 40A, and the first-type tape distal end nipping portion 16A are portions for molding the distal end portion 1A of the first-type tape 1A after cutting, and these portions are collectively referred to as a first molding mechanism Mo1 (see fig. 1 and 5), respectively. The second tape holding portion 31, the second-type tape distal end supporting portion 40B, and the second-type tape distal end clamping portion 16B are portions for molding the distal end portion 1a of the cut second-type tape 1B, and these portions are collectively referred to as a second molding mechanism Mo2 (see fig. 1 and 5), respectively.

The pressing member 17 presses (presses) the first-type tape distal end gripping section 16A and the second-type tape distal end gripping section 16B provided at the temporary position P2 from above. The pressing member 17 is fixed to the second member 21, and is displaced (rotated) integrally with the second blade 21a about the pivot shaft 23.

As shown in fig. 1, the pressing member 17 includes a bracket 60 fixed to the second member 21, and a pair of front and rear pressing portions 62A and 62B (a first pressing portion 62A and a second pressing portion 62B) fixed to the bracket 60.

The bracket 60 is a press-formed product of a metal plate, for example. The bracket 60 is located outside the second blade portion 21a (i.e., on the opposite side of the first blade portion 20a with the second blade portion 21a therebetween), and has a vertical plate portion 61a that is substantially parallel to the second blade portion 21a and extends in the direction along the blade line thereof, and an upper plate portion 61b that extends from the upper end of the vertical plate portion toward the table 14. The vertical plate portion 61a and the upper plate portion 61b form a substantially right angle.

The pair of pressurizing portions 62A and 62B are fixed to the upper plate portion 61B. Each of the pressurizing portions 62A, 62B is constituted by a plunger similar to the restricting member 56 of the distal end gripping portions 16A, 16B. That is, the pressurizing portions 62A and 62B (plunger pistons) are respectively constituted by a cylinder portion 63a fixed to the upper plate portion 61B, a pin portion 63B (corresponding to an "abutting portion" of the present invention) held movably in and out of the cylinder portion 63a, and a spring member 63c (refer to fig. 10A/corresponding to an "urging member" of the present invention) incorporated in the cylinder portion 63a and urging the pin portion 63B in a direction to project. The pressing portions 62A and 62B are fixed to the upper plate portion 61B in a state where the pin portion 63B protrudes downward from the upper plate portion 61B. Thereby, with the cutting operation of the jig main body 12, the distal end gripping portions 16A, 16B provided on the provisional position P2 can be pressurized from above by the pressurizing member 17. Specifically, the first pressing portion 62A on the rear side presses (presses) the molding portion 51a of the distal end holding portion 16A for the first type tape, and the second pressing portion 62B on the front side presses the molding portion 51B of the distal end holding portion 16B for the second type tape.

Further, the pressing portions 62A, 62B are provided at positions offset upward with respect to the edge line of the second blade portion 21a, that is, at positions offset in the rotational delay direction of the second blade portion 21a, so that the pressing of the forming portions 51a, 51B is started after the two blade portions 20a, 21a are displaced to the positions at which the cutting of the component tape 1 is completed in the cutting operation. The pressurizing portions 62A and 62B are fixed to the holder 60 as follows: in the combined state of the jig main body 12 in which the first grip portion 20b and the second grip portion 21b abut against each other and the first blade portion 20a and the second blade portion 21a overlap with each other, the pin portion 63b is located in the middle of the movable stroke, that is, the forming portions 51a and 51b are pressurized based on the elastic force (urging force) of the spring member 63c built in the cylinder portion 63 a.

In the tape cutting jig 10 described above, the first tape holding portion 30, the first type tape distal end supporting portion 40A, and the first type tape distal end clamping portion 16A correspond to the "tape holding portion", "distal end supporting portion", and "distal end clamping portion" of the present invention, respectively. The molding portion 41 and the molding portion 51a correspond to the "first molding portion" and the "second molding portion" of the present invention, respectively.

[ processing steps of the component tape 1 ]

Next, a procedure of processing the component tape 1 using the tape cutting jig 10 will be described. First, the processing steps of the first type tape 1A (the arrangement pitch of the component accommodation portions 2a is 2mm) shown in fig. 2B will be described with reference to fig. 7 to 11B.

First, in a state where the jig main body 12 is set to the open state, as shown in fig. 6 to 9A, the first type tape 1A is set in the first pitch holding portion 32 of the first tape holding portion 30.

Specifically, the first type tape 1A is arranged so as to cross the jig main body 12, and the positioning pins 37a, 37a are inserted into the feeding holes 2 b. At this time, the first type tape 1A is provided so that the cover tape 3 is positioned on the upper side (the side opposite to the upper surface 14 a) in the forward direction. Thereby, the first type tape 1A is positioned at the first tape holding portion 30.

Next, the tape fixing member 18 is provided from above the first type tape 1A. Specifically, the tape fixing member 18 is disposed between the restricting pins 46b and 46b in the process of inserting the fixing pin 46a into the through hole 18 a. The tape fixing member 18 after the setting is held on the table 14 based on the magnetic force of the magnet 47. Thus, the first type tape 1A is fixed to the table 14 (the first pitch holding portion 32) in the above-described positioned state.

Next, the first-type tape distal end holding portion 16A is provided. That is, the first-type-tape distal end gripper 16A is moved (rotated) from the retreat position P0 to the temporary position P2. In this state, as shown by the solid line in fig. 6, the pin portion 57B of the regulating member 56 protrudes, and as shown in fig. 9B, the forming portion 51a is held at a position away from the forming portion 41 of the first-type tape distal end support portion 40A. That is, the molding portion 51A and the molding portion 41 of the first-type tape distal end support portion 40A do not yet sandwich the first-type tape 1A.

Next, as shown in fig. 10A, a cutting operation is performed. That is, the first grip 20b and the second grip 21b of the jig main body 12 are gripped, and the first type tape 1A is held between the first blade 20a and the second blade 21A by gripping these grips.

Based on this cutting operation, first, the first type tape 1A is sandwiched between the first blade portion 20a and the second blade portion 21A, and the first type tape 1A is cut. At this time, there is still a gap C between the pressing portion 62A (pin portion 63B) of the pressing member 17 and the first-type-tape distal-end holding portion 16A (forming portion 51A), and as shown in fig. 10B, the distal end portion 1A of the first-type tape 1A is not held between the forming portion 51A and the forming portion 41 of the first-type-tape distal-end supporting portion 40A. Then, when the cutting operation is further performed, as shown in fig. 11A, the pressing portion 62A (the pin portion 63b) of the pressing member 17 abuts on the first-type-tape distal end nip portion 16A (the forming portion 51A), so that the first-type-tape distal end nip portion 16A is pressed. Accordingly, the pin portion 57b of the restricting member 56 is retracted into the cylinder portion 57a, and the first-type tape distal end gripping portion 16A is displaced from the temporary position P2 to the molding position P1. After the jig main body 12 is in the complete cutting state, as shown in fig. 11B, the distal end portion 1A of the first type tape 1A is clamped between the molding portion 51A and the molding portion 41 of the first type tape distal end supporting portion 40A, and the distal end portion 1A is molded.

In this way, by performing the cutting operation until the jig main body 12 is brought into the complete cutting state, the cutting of the first type tape 1A and the molding of the distal end portion 1A thereof can be continuously performed. Further, the subsequent unloading of the first type web 1A may be performed by a reverse procedure to the above-described procedure.

The above is a step of processing the first type tape 1A having the arrangement pitch of the element housing portions 2a of 2 mm. When the first type tape 1A having the arrangement pitch of the element accommodating portions 2a of 4mm is processed, the first type tape 1A is set in the second pitch holding portion 33, and the operation is performed in the same manner as the above-described steps. This enables the first type tape 1A to be processed in the same manner.

Next, a process of processing the second type tape 1B (the arrangement pitch of the element housing portions 2a is 2mm) shown in fig. 2C will be described. Here, the steps common to the processing steps of the first type material belt 1A will be briefly described.

First, as shown in fig. 12, the second type tape 1B is set in the first pitch holding portion 32 of the first tape holding portion 30, and the tape fixing member 18 is set from above. In this case, the second type tape 1B is arranged in a reversed manner, that is, in such a manner that the cover tape 3 is located on the lower side (upper surface 14a side). In the case of the second tape 1B, although a portion of the element receiving portion 2a protrudes toward the bottom surface side, the protruding portion is inserted into a notch portion 19a on the rear side of the tape fixing member 18 as shown in fig. 12. Therefore, the second type tape 1B is fixed to the table 14 by the tape fixing member 18 (the first pitch holding portion 32) in a state where the protruding portion is received in the notch portion 19 a.

Next, a dicing operation is performed as shown in fig. 13A and 13B. At this time, the cutting operation is performed without providing the first-type tape distal end holding portion 16A. Thereby, only the cutting of the second type of material strips 1B is performed.

After cutting, the tape fastener 18 is removed. The second tape 1B is temporarily removed from the first tape holding section 30 (the first pitch holding section 32), and is again set in the first pitch holding section 34 of the second tape holding section 31. The second type of tape 1B is arranged upside down. At this time, the positioning pins 37c, 37c are inserted into the two feed holes 2B close to the distal end portion 1a of the second-type material tape 1B. By thus providing the second type tape 1B to the first space holding portion 34, the distal end portion 1a of the second type tape 1B is arranged at the forming portion 42 of the second type tape distal end supporting portion 40B.

Next, the holder body 12 is restored to the open state. After the second-type tape distal end holding portion 16B is set (set at the temporary position P2), the cutting operation is performed again. Thereby, as shown in fig. 14A, the distal end holding portion 16B (molding portion 51B) for the second type tape is pressurized by the pressurizing member 17. By this pressing, the second-type tape distal end holding portion 16B is displaced from the provisional position P2 to the molding position P1, and as shown in fig. 14B, the distal end portion 1a of the second-type tape 1B is held between the molding portion 51B and the molding portion 42 of the second-type tape distal end support portion 40B, and an arc-shaped curved portion is molded at the widthwise central portion of the distal end portion 1a based on the concave portion 14c and the convex portion 54B. In addition, the second type tape 1B can be discharged by the reverse procedure of the above procedure.

The above is a step of processing the second type tape 1B having the arrangement pitch of the element housing portions 2a of 2 mm. When the second type tape 1B having the arrangement pitch of the element accommodating portions 2a of 4mm is processed, the second type tape 1B is first set in the second pitch holding portion 33 of the first tape holding portion 30, and after the second type tape 1B is cut, the second type tape 1B is set in the second pitch holding portion 35 of the second tape holding portion 31, and the distal end portion 1a of the second type tape 1B is molded. The other steps are the same as the steps of the processing of the second type tape 1B described above.

[ Effect ]

According to the tape cutting jig 10 described above, the cutting operation of the component tape 1 and the molding operation of the distal end portion 1a of the component tape 1 can be performed by the same jig. In particular, in the case where the component tape 1 is the first type tape 1A, the cutting and molding of the first type tape 1A can be continuously performed by one cutting operation. In addition, since the tape cutting jig 10 cuts the component tape 1 while holding the component tape 1 by the table 14 (tape holding section 30) provided on the side of the first blade 20a of the jig main body 12, based on the scissor-type jig main body 12, the cutting position of the component tape 1 can be easily seen. Even when the blade length dimensions of the first blade 20a and the second blade 21a are increased to cope with the wide component tape 1, the positions of the first blade 20a and the second blade 21a and the positions of the first grip 20b and the second grip 21b are separated from each other in the front-rear direction, and therefore, the influence on the operability is small as compared with a conventional stapler-type jig in which the blades (blades) and the grips are located at substantially the same positions. That is, the size of the cutting tool is not increased, and the cutting operation is not difficult because the tool is difficult to hold. Therefore, the tape cutting jig 10 is easily adaptable to the component tape 1 having a relatively large width, and is a more easily usable jig capable of performing work while visually checking the cutting position of the component tape 1.

Further, according to the tape cutting jig 10, not only the two types of component tapes 1 having different arrangement pitches of the component storage sections 2a but also the two types of component tapes 1 having different structures, specifically, the first type tape 1A having the paper carrier tape 2 having a predetermined thickness without unevenness on the bottom surface and the second type tape 1B having the resin carrier tape 2 in which the portion corresponding to the component storage section 2a is embossed so as to protrude toward the bottom surface side can be processed. Therefore, the tape cutting jig 10 can be used for a wide variety of component tapes 1, and is convenient.

Further, according to the tape cutting jig 10, since the first forming mechanism portion Mo1 and the second forming mechanism portion Mo2 are provided, the distal end portion 1A of the component tape 1 can be formed into different shapes according to the type of the component tape 1 (that is, according to the first type of tape 1A or the second type of tape 1B). That is, the tape cutting jig 10 can be used in common to mold the distal end portions 1a of the component tapes 1 into different shapes, and therefore, is excellent in convenience.

Further, according to the tape cutting jig 10, by providing or not providing the first type tape distal end holding portion 16A, it is possible to select whether to perform both the cutting operation and the forming operation of the component tape 1 or to perform only the cutting operation. In the above embodiment, as described above, both the cutting operation and the forming operation are performed by providing the first-type tape distal end holding portion 16A for the first-type tape 1A, and only the cutting operation is performed without providing the first-type tape distal end holding portion 16A for the second-type tape 1B. Therefore, the tape cutting jig 10 has the following advantages: when the component tape 1 is cut, whether or not the distal end portion 1a of the component tape 1 is formed can be arbitrarily selected.

Further, as described above, the molded portion 51a of the first-type-web distal end holding portion 16A is displaced around the pivot shaft 52a with the distance relationship between the molded portion 51a and the molded portion 41 of the first-type-web distal end support portion 40A in the longitudinal direction (front-rear direction) thereof being maintained equal. Therefore, the distal end portion 1a of the element tape 1 can be held with uniform pressure over the width direction thereof. Therefore, the tape cutting jig 10 also has the following advantages: the distal end portion 1A of the component tape 1 (the first type tape 1A) can be molded more appropriately over the entire width thereof. The same applies to the case where the distal end portion 1a of the second type tape 1B is molded by the distal end holding portion 16B (molding portion 51B) for the second type tape and the distal end supporting portion 40B (molding portion 42) for the second type tape.

Further, according to this tape cutting jig 10, even if the cutting operation is performed in a state where the first-type tape distal end holding portion 16A is provided, the component tape 1 is not held by the first-type tape distal end holding portion 16A and the first-type tape distal end support portion 40A until the cutting of the component tape 1 is completed, that is, until the first-type tape distal end holding portion 16A (the molding portion 51a) is pressed by the pressing member 17 (refer to fig. 10A to 11B). Therefore, it is possible to prevent the occurrence of a problem that the component tape 1 is accidentally pressed by the first-type tape distal end holding portion 16A (the molding portion 51a) to cause a deviation in the cutting position or the like at the cutting stage of the component tape 1.

Further, according to the tape cutting jig 10, since the pressing portions 62A and 62B are provided on the pressing member 17, as shown in fig. 11A and 14A, the distal end holding portions 16A and 16B can be pressed by the elastic force of the spring piece 63c built in the pressing portions 62A and 62B as long as the cutting operation is performed until the jig main body 12 is in the complete cutting state. That is, when the cutting operation is performed until the holder body 12 is completely closed, the distal end clamping portions 16A and 16B are pressed by a predetermined urging force. Therefore, variation in molding accuracy due to differences between operators can be suppressed, and as a result, the molding accuracy of the distal end portion 1a of the element tape 1 can be maintained more uniformly.

[ second embodiment ]

Fig. 15A is a main perspective view of a tape cutting jig 11 according to a second embodiment of the present invention. Since most of the configuration of the tape cutting jig 11 of the second embodiment is common to the tape cutting jig 10 of the first embodiment, the same reference numerals are given to common points with those of the first embodiment in the following description, and the description thereof will be omitted or simplified, and the points different from the first embodiment will be mainly described in detail.

In brief, the tape cutting jig 11 of the second embodiment is a jig in which the second tape holding portion 31 is omitted. That is, only the first tape holding unit 30 (hereinafter, simply referred to as the tape holding unit 30) is provided on the table 14. Therefore, the second-type tape distal end support portion 40B is provided separately from the table 14. Specifically, the metal block-shaped distal end support portion 40B for the second type tape is disposed in front of the jig main body 12. The second-type tape distal end support portion 40B has a molding portion 42 including an upper surface 43 substantially flush with the upper surface 14a of the table 14 and two groove-like recesses 43a formed in the upper surface 43. Each of the concave portions 43b has a shape equivalent to that of the concave portion 14c of the first embodiment, and has a substantially semicircular cross-sectional shape extending in the width direction in parallel with each other.

Further, a guide rail 70 extending in the front-rear direction is fixed to the bracket 15, and the table 14 is movably attached to the guide rail 70. Thus, the table 14 (i.e., the tape holder 30) is movable in a range between a first working position a1 shown in fig. 15A and a second working position a2 shown in fig. 15B, the first working position a1 being a position facing the first blade portion 20a in the width direction, and the second working position a2 being a position facing the second type tape distal end support portion 40B in the width direction.

Further, a positioning mechanism for positioning the table 14 at each of the first working position a1 and the second working position a2 is provided in the tape cutting jig 11. In this example, the positioning mechanism is a stopper mechanism, but it may be other mechanism.

As shown in fig. 16A, the stopper mechanism is composed of a plunger 72 fixed to the table 14, two recesses 74A, 74B formed in the holder 15, and a pair of stoppers 75, 75 that limit the movable region of the table 14. The plunger 72 is a so-called ball plunger including a cylinder portion 73a, a ball (rigid ball) 73b rollably held by the cylinder portion 73a so as to be movable in and out, and an unillustrated spring member that applies a biasing force in a direction to project the ball 73 b. The plunger 72 is fixed to the table 14 in a state where the ball 73b is pressed against the holder 15, so that the ball 73b rolls in accordance with the movement of the table 14. Recesses 74A and 74B into which the ball 73B can be fitted are formed at positions corresponding to the first working position a1 and the second working position a2 on the moving path of the ball 73B in the bracket 15. That is, when the table 14 is disposed at the first working position a1, as shown in fig. 16A, the balls 73B are fitted into the rear recesses 74A, and the table 14 is held at the first working position a1, and when the table 14 is disposed at the second working position a2, as shown in fig. 16B, the balls 73B are fitted into the front recesses 74B, and the table 14 is held at the second working position a 2.

The pair of stoppers 75, 75 are formed by, for example, heads of bolts attached to the bracket 15, one of which is disposed at a predetermined position behind the first working position a1, and the other of which is disposed at a predetermined position in front of the second working position a 2. Thereby, the movable region of the table 14 is limited between the first working position a1 and the second working position a 2.

Next, a procedure of processing the component tape 1 by the tape cutting jig 11 of the second embodiment will be described.

First, a processing process of the second type tape 1B (the arrangement pitch of the element housing portions 2a is 4mm) shown in fig. 2C will be described.

First, the table 14 is set to the first working position a 1. As shown in fig. 15A, the second type tape 1B is set in the tape holding portion 30 (second pitch holding portion 33) and fixed by the tape fixing member 18. Thereafter, a cutting operation is performed to cut the second type of strip of material 1B as shown in fig. 17A.

After the cutting operation of the second type tape 1B is completed, the jig main body 12 is returned to the open state, and the table 14 is moved from the first operation position a1 to the second operation position a2 while the second type tape 1B is held in the first pitch holding portion 32. Thereby, the distal end portion 1a of the second type tape 1B is slid from the position of the first blade portion 20a to the formation portion 42 of the second type tape distal end support portion 40B. Then, as shown in fig. 17B, after the second-type tape distal end holding portion 16B is provided, the cutting operation is performed again. As a result, as shown in fig. 17C, the distal end portion 1a of the second type tape 1B is sandwiched between the molding portion 51B and the molding portion 42 of the second type tape distal end support portion 40B, and the distal end portion 1a is molded.

The second type tape 1B having the element housing portions 2a arranged at the pitch of 2mm may be processed in the same manner as described above, except that the second type tape 1B is provided in the first pitch holding portion 32.

On the other hand, when the first type tape 1A as shown in fig. 2B is subjected to the processing, the steps in this case are not significantly different from those in the case of using the tape cutting jig 10 of the first embodiment. That is, first, the table 14 is set at the first working position a 1. Further, the first type tape 1A is set to the tape holding section 30 and fixed by the tape fixing member 18, and thereafter, the first type tape distal end holding section 16A is set. At this time, in the case of the first type tape 1A having the array pitch of the element accommodating portions 2a of 2mm, the first type tape 1A is set in the first pitch holding portion 32, and in the case of the first type tape 1A having the array pitch of the element accommodating portions 2a of 4mm, the first type tape 1A is set in the second pitch holding portion 33.

Thereafter, a cutting operation is performed. This enables the cutting operation and the forming operation of the first type tape 1A to be performed continuously.

According to the tape cutting jig 11 of the second embodiment as described above, the workability of the processing of the second type tape 1B can be particularly improved. That is, according to the tape cutting jig 11, after the second type tape 1B is cut, the distal end portion 1a of the second type tape 1B can be arranged at the second type tape distal end supporting portion 40B by moving the table 14 from the first working position a1 to the second working position a2 while maintaining the second type tape 1B fixed to the tape holding portion 30. Therefore, it is not necessary to perform the operation of once detaching the second type tape 1B from the first tape holding portion 30 and resetting the second type tape to the second tape holding portion 31 after the tape cutting as in the first embodiment. Therefore, the tape cutting jig 11 according to the second embodiment has the following advantages: the same operational effects as those of the tape cutting jig 10 of the first embodiment described above can be obtained, and in particular, the workability of the processing of the second type tape 1B can be improved.

In the second embodiment, the first-type-tape distal end support portion 40A and the first-type-tape distal end holding portion 16A correspond to the "first distal end support portion" and the "first distal end holding portion" of the present invention, respectively, and the second-type-tape distal end support portion 40B and the second-type-tape distal end holding portion 16B correspond to the "second distal end support portion" and the "second distal end holding portion" of the present invention, respectively.

[ other modifications, etc. ]

The tape cutting jigs 10 and 11 described above are examples of preferred embodiments of the tape cutting jig according to the present invention, and specific configurations thereof may be modified as appropriate within a range not departing from the gist of the present invention. For example, the following structure can be applied.

In the embodiment, the following clips are described as the tape cutting clips 10 and 11: the first type tape 1A is formed so that its distal end portion 1A is curved upward (see fig. 11B), and the second type tape 1B is formed so that a curved portion having a circular arc shape is formed at the widthwise central portion of its distal end portion 1A. However, the tape cutting jigs 10, 11 may be applied to a case where the distal end portion 1a of the component tape 1 is formed into a shape other than the above.

In the embodiment, the distal end gripping portions 16A and 16B are rotatably provided on the table 14 (tape holding portions 30 and 31). That is, the distal end clamping portions 16A, 16B are provided on the first member 20 side. However, each distal end holding portion 16A, 16B may be provided on the second member 21 side. For example, each distal end gripping portion 16A, 16B may be provided in the following manner: the tape is moved together with the second blade 21a, and after the component tape 1 is cut by the jig main body 12 (the first blade 20A and the second blade 21a), the distal end portion 1a of the component tape 1 is clamped together with the tape distal end support portions 40A and 40B.

In the embodiment, the restriction member 56 for holding the distal end holding portions 16A and 16B at the temporary position P2 is provided on each of the distal end holding portions 16A and 16B. However, the restriction member 56 may be omitted and the distal end clamping portions 16A and 16B arranged at the molding position P1 may be pressed (pushed) by the pressing member 17.

The tape cutting jigs 10 and 11 in the embodiment are configured to process the component tapes 1 of two types, i.e., the first type tape 1A and the second type tape 1B. However, the tape cutting jigs 10 and 11 may be configured to perform the processing only on one type of the component tape 1.

The present invention described above based on the embodiments is summarized as follows.

The tape cutting jig of the present invention is a jig for cutting a tape for use in feeding components, in which component accommodating portions are arranged at a predetermined interval in a longitudinal direction, and includes: a scissor-type jig main body which is provided with a first blade, a second blade, and a pair of grippers, and cuts the tape clamped between the first blade and the second blade by receiving a cutting operation of gripping the pair of grippers; a tape holding section disposed on a side of the first blade section, provided so as to be displaceable together with the first blade section, and holding the tape in a state of intersecting the first blade section and the second blade section; a distal end support portion that supports a distal end portion of the tape cut by the first blade portion and the second blade portion; and a distal end holding portion for holding the distal end portion of the tape cut by the first blade portion and the second blade portion together with the distal end support portion; wherein the tape holding section holds the tape in a state where the tape is positioned so that the tape is cut at a position between the adjacent element housing sections, the distal end supporting section and the distal end holding section each include a first molding section and a second molding section, and the distal end section of the cut tape is molded into a predetermined shape by holding the distal end section together with the first molding section and the second molding section.

In the tape cutting jig, the tape is held in the tape holding section in a state of intersecting the first and second blade sections, and the tape is cut by the first and second blade sections by holding the pair of grip sections and the cut tape is held between the first molding section of the distal end support section and the second molding section of the distal end holding section, so that the distal end section is molded into a predetermined shape. Therefore, the cutting operation of the tape and the forming operation of the distal end portion of the tape can be continuously performed by the same jig. In addition, since the tape cutting jig is based on the scissor-type jig main body, and the tape is cut while being held by the tape holding portion provided on the side of the first blade portion of the jig main body as described above, the cutting position of the tape is easily visible. Further, even when the blade length of the first and second blades is increased to cope with a wide tape, since the positions of the first and second blades and the positions of the pair of grip portions are separated from each other, the influence on the operability is small as compared with a conventional stapler-type jig in which the blades (blades) and the grip portions are located at substantially the same positions. Therefore, the material belt cutting clamp is an easy-to-use material belt cutting clamp as follows: the tape can be easily handled even for the supply of components having a relatively large tape width, and the operation can be performed with the tape cutting position being visually recognized.

In the tape cutting jig, the distal end holding portion is supported by the tape holding portion so as to be displaceable between a molding position at which the distal end portion of the tape is held between the first molding portion and the second molding portion and a predetermined retreat position at which the distal end portion is released by retreating from the molding position, and the jig main body includes a pressing member which is fixedly provided to the second blade portion and presses the second molding portion of the distal end holding portion when the distal end holding portion is provided at the molding position.

In the tape cutting jig, the distal end portion of the tape is molded by the first and second molding portions only when the distal end holding portion is set at the molding position. Therefore, at the time of cutting of the tape, it is possible to select whether or not the distal end portion of the tape is formed into the prescribed shape.

In addition, above-mentioned material area cutting jig still includes: a regulating member for positioning the distal end holding portion at a predetermined temporary position between the molding position and the retracted position and before the tape is held between the first molding portion and the second molding portion; wherein the pressing member presses the second molding portion of the distal end holding portion held at the temporary position after the tape is cut by the cutting operation of the jig main body, and the restricting member allows the distal end holding portion to be displaced from the temporary position to the molding position based on the second molding portion being pressed by the pressing member.

According to this structure, even if the cutting operation is performed in a state where the distal end holding portion is set at the temporary position, the tape is not held by the first molding portion of the distal end support portion and the second molding portion of the distal end holding portion until the cutting of the tape is completed. Therefore, the problem that the distal end clamping portion presses the tape to cause deviation of the cutting position when the tape is cut can be prevented.

In the tape cutting jig, the pressing member includes an abutting portion abutting against the second molding portion and a biasing member biasing the abutting portion, and presses the second molding portion based on the biasing force of the biasing member.

According to this configuration, the distal end portion of the tape can be held with a more uniform pressure, and therefore, the molding accuracy of the distal end portion of the tape can be uniformly maintained.

In the tape cutting jig, the distal end holding portion is supported by the tape holding portion so as to be rotatable about an axis extending in a direction orthogonal to the longitudinal direction of the tape held by the tape holding portion, and the first molding portion and the second molding portion extend parallel to the orthogonal direction.

According to this configuration, the tape can be held with a uniform pressure in the width direction of the tape, that is, in the range of the direction orthogonal to the longitudinal direction of the tape. Therefore, the distal end portion of the tape can be more appropriately molded into the prescribed shape.

In the tape cutting jig, the tape holding section includes a first holding section for holding the first tape and a second holding section provided adjacent to the first holding section for holding the second tape, the second tape being a tape in which the arrangement pitch of the element accommodating sections is different from that of the first tape.

With this configuration, the tape cutting jig can be used for cutting two types of tapes having different arrangement pitches of the component storage sections and forming the distal end portion.

In the above-mentioned material tape cutting jig, the material tape holding portion has a material tape holding surface, and the material tape cutting jig further includes: and the material belt fixing piece is used for fixing the material belt on the material belt retaining surface.

According to this structure, the cutting operation of the material tape can be performed more stably.

In the above tape cutting jig, when the tape holding portion, the distal end support portion, and the distal end holding portion are defined as a first molding mechanism portion, a second molding mechanism portion for molding the distal end portion of the tape into a shape different from the molded shape molded by the first molding mechanism portion is provided at a position adjacent to the first molding mechanism portion, and the second molding mechanism portion includes the tape holding portion, the distal end support portion, and the distal end holding portion.

According to this configuration, the distal end portion of the tape can be selectively formed into different shapes by a common tape cutting jig.

In the above tape cutting jig, when the tape holding portion, the distal end support portion, and the distal end holding portion are defined as first molding mechanism portions, a second molding mechanism portion for molding the distal end portion of the tape into a shape different from the molding shape molded by the first molding mechanism portion is provided at a position adjacent to the first molding mechanism portion, the second molding mechanism portion includes the tape holding portion, the distal end support portion, and the distal end holding portion, and the pressing member includes a first pressing portion that presses the second molding portion of the distal end holding portion of the first molding mechanism portion, and a second pressing portion that presses the second molding portion of the distal end holding portion of the second molding mechanism portion.

With this configuration, the distal end portion of the tape can be selectively formed into different shapes by a common tape cutting jig. In particular, since the molding section is pressurized by each of the pressurizing sections, the distal end portion of the tape can be molded more appropriately.

In the above tape cutting jig, when the distal end support portion is defined as a first distal end support portion and the distal end holding portion is defined as a first distal end holding portion, the tape cutting jig further includes a second distal end support portion disposed in front of the first blade portion in a direction orthogonal to a longitudinal direction of the tape held by the tape holding portion, and a second distal end holding portion supported by the tape holding portion and configured to hold a distal end portion of the tape together with the second distal end support portion, the tape holding portion being provided so as to be movable in the orthogonal direction with respect to the jig main body between a first working position facing a side surface of the first blade portion and a second working position facing the second distal end support portion, and the tape holding portion being disposed in the first working position, the first distal end holding portion holds a distal end portion of the tape together with the first distal end supporting portion, the second distal end holding portion holds the distal end portion of the tape together with the second distal end supporting portion in a state where the tape holding portion is arranged at the second working position, and the first molding portion and the second molding portion of the second distal end holding portion mold the distal end portion of the tape into a shape different from a molding shape molded by the first distal end supporting portion and the first molding portion and the second molding portion of the first distal end holding portion.

According to this configuration, the following operation mode can be executed: a working mode of cutting the tape in a state that the tape holding part is configured at the first working position, and forming the distal end part of the tape by the first distal end supporting part and the first distal end clamping part in the state; and an operation mode in which the tape holding section is cut in a state in which the tape holding section is disposed at the first operation position, then the tape holding section is moved to the second operation position, and the distal end portion of the tape is molded by the second distal end support section and the second distal end nip section. Thus, the distal end portion of the strip of material can be selectively formed into different shapes by a common strip cutting jig.

In the above tape cutting jig, when the distal end support portion is defined as a first distal end support portion and the distal end holding portion is defined as a first distal end holding portion, the tape cutting jig further includes a second distal end support portion disposed in front of the first blade portion in a direction orthogonal to a longitudinal direction of the tape held by the tape holding portion, and a second distal end holding portion supported by the tape holding portion and configured to hold a distal end portion of the tape together with the second distal end support portion, the tape holding portion being provided so as to be movable in the orthogonal direction with respect to the jig main body between a first working position facing a side surface of the first blade portion and a second working position facing the second distal end support portion, and the tape holding portion being disposed in the first working position, the first distal end holding portion holds the distal end portion of the tape together with the first distal end supporting portion, the second distal end holding portion holds the distal end portion of the tape together with the second distal end supporting portion in a state where the tape holding portion is arranged at the second operation position, the pressing member includes a first pressing portion for pressing the second forming portion of the first distal end holding portion and a second pressing portion for pressing the second forming portion of the second distal end holding portion, and the first forming portion and the second forming portion of the second distal end supporting portion and the second distal end holding portion form the distal end portion of the tape into a shape different from the forming shapes formed by the first forming portion and the second forming portion of the first distal end supporting portion and the first distal end holding portion.

In the case of this configuration, the distal end portion of the tape can be selectively formed into a different shape by a common tape cutting jig as described above. In particular, since the molding section is pressurized by each of the pressurizing sections, the distal end portion of the tape can be molded more appropriately.
