Description

  The present invention relates to a tape feeder that supplies electronic components by feeding a carrier tape wound around a reel.

  Tape feeders are widely used as devices for supplying electronic components to electronic component mounting apparatuses. In the tape feeder, a carrier tape containing electronic components at an equal pitch is used as a supply medium for the electronic components, and the carrier tapes are pitch-fed so that the electronic components accommodated at an equal pitch are sequentially supplied to predetermined positions. It is like that. The tape feeder is used in a state of being mounted on the electronic component mounting apparatus, and a predetermined position where the electronic component is supplied is a pickup position by a mounting head provided in the electronic component mounting apparatus. The carrier tape is stored in a state where the carrier tape is wound around a reel in a tape storage unit provided separately from the tape feed unit provided with the tape feed mechanism for performing the pitch feed operation described above, and formed in the tape feed unit. The tape is fed into the tape feeding section from the tape introduction port and pitch-fed.

The tape feeder configured as described above includes a multi-type tape feeder that can simultaneously feed a plurality of carrier tapes for the purpose of supplying a plurality of electronic components simultaneously. In such a tape feeder, a plurality of reels are stored in the tape storage portion in a state of being parallel in the radial direction, and the carrier tapes are in a state of being parallel in the lateral direction in a plurality of lanes provided at the tape inlet. It is designed to be pulled into the tape feeding section from the introduction port (see Patent Document 1).
JP 2004-6470 A

  However, since the plurality of carrier tapes stored in a line in the tape storage unit are drawn in from the tape introduction port to the tape feeding unit in a state of being aligned in a horizontal line, they are twisted between each reel and each lane. It was difficult to identify at a glance which reel the carrier tape was wound on by passing through the path. For this reason, when checking electronic components, the carrier tape is confirmed between the lane and the reel and the electronic component information recorded on the corresponding reel is acquired. At the same time, there is a possibility that the electronic component information recorded on another reel may be mistaken.

  Then, an object of this invention is to provide the tape feeder excellent in the discernment property of a carrier tape.

  The invention according to claim 1 includes a tape feeding unit that feeds a plurality of carrier tapes, and a reel storage unit that stores a plurality of reels each wound around the plurality of carrier tapes below the tape feeding unit. A tape feeder that introduces the carrier tape wound around the reel into the tape feeding portion, and a tape support portion that supports the carrier tape from below and guides it to the inlet. A plurality of lanes for restricting the introduction position of each carrier tape at the tape introduction port, and the tape support portion has a different support length for supporting the carrier tape from below for each lane.

According to the present invention, since there is a difference in the carrier tape support length for each lane into which a plurality of carrier tapes are introduced into the tape feeding portion, the carrier tape is introduced into each lane located above from each reel located below. Differences occur in the curves drawn by each carrier tape. Thereby, even if there is no apparent difference in the carrier tape itself, it can be easily identified at a glance which carrier tape it is.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of an electronic component mounting apparatus according to an embodiment of the present invention, and FIG. 2 is an enlarged view around a tape inlet of a tape feeder according to an embodiment of the present invention.

  First, the overall configuration of the electronic component mounting apparatus will be described with reference to FIG. In FIG. 1, an electronic component mounting apparatus 1 has a function of mounting an electronic component supplied from a tape feeder 2 containing a plurality of electronic components on a substrate 3. The tape feeder 2 uses a carrier tape 4 containing electronic components at an equal pitch as a supply medium for the electronic components, and is introduced into the tape feeding unit 5 from a tape inlet 6 provided at the rear of the tape feeding unit 5. Electronic components are sequentially supplied to the component supply port 7 by pitch-feeding the carrier tape 4 to the front portion by a tape feeding mechanism (not shown). The tape feeder 2 is of a multi-type that supplies a plurality of electronic components to the component supply port 7 in a parallel state, so that a plurality of carrier tapes 4 can be introduced from the tape introduction port 6 and pitched simultaneously. It has become. A plurality of reels 8 for storing a plurality of carrier tapes 4 in a wound state are juxtaposed in the radial direction below the tape feeding section 5 (the tape feeder of the present embodiment supplies two electronic components simultaneously) This is a double feeder that is configured to be capable of storing two carrier tapes 4 wound around dedicated reels 8).

  The tape feeder 5 is mounted on the base 10 in a state where the tape feeder 5 is supported at a predetermined height by the carrier 9. In a state where the tape feeding unit 5 is mounted on the base 10, the component supply port 7 is a pickup position by the mounting head 11 provided in the electronic component mounting apparatus 1. The substrate 3 is held at a predetermined position by a substrate transport path 12 provided on the base 10. The board carrying path 12 carries the board 3 before mounting into the electronic component mounting apparatus 1 and also carries the board 3 after mounting from the electronic component mounting apparatus 1 and the board 3 before mounting. A holding function for temporarily holding at the position is provided. The mounting head 11 is configured to be horizontally movable by horizontal movement means such as an orthogonal robot (not shown), and has a function of picking up an electronic component supplied from the tape feeder 2 and transferring it to the substrate 3 held at a predetermined position. I have. The nozzle 13 attached to the lower portion of the mounting head 11 is configured to be vertically movable with respect to the mounting head 11 and to be rotatable in a horizontal plane. Therefore, the electronic component sucked by the nozzle 13 can be changed to an arbitrary position and angle by the horizontal movement of the orthogonal robot and the rotation of the nozzle 13, and based on the analysis result of the image taken from below by the recognition camera 14. The electronic component is mounted on the substrate 3 after the positional deviation is corrected.

Next, the tape inlet of the tape feeder will be described with reference to FIG. FIG. 2 shows a state in which two carrier tapes 4a and 4b are introduced into the tape introduction port 6. FIG. 2A is a rear view of the tape feeder 2 as viewed from the rear, and FIGS. It is the side view seen from both sides of. In FIG. 2A, the tape introduction opening 6 opened at the rear part of the tape feeding section 5 is divided into a plurality of lanes (two lanes 6a and 6b in the tape feeder of the present embodiment) in the lateral direction. . Each lane 6a, 6b is opened in a rectangular shape having a width that is slightly larger than the width of the carrier tape 4a, 4b and a vertical width that is more than the thickness of the carrier tape 4a, 4b. 4 a and 4 b are introduced into the tape feeding section 5. As a result, the introduction positions of the carrier tapes 4a and 4b are regulated by the lanes 6a and 6b, respectively, are pitch-fed along the feeding path formed inside the tape feeding part 5, and the electronic components Pa and Pb is component supply port 7
Are supplied in parallel.

  In FIG. 2B, a tape support portion 15 a having an upper surface continuous with the lower end of the lane 6 a is projected toward the rear of the tape feeder 2. The tape support portion 15a has a function of supporting the carrier tape 4a from below and forcibly changing the posture to a horizontal posture when the carrier tape 4a wound and accommodated on the lower reel 8 is introduced into the upper lane 6a. I have. By this tape support portion 15a, the carrier tape 4a changes its posture while drawing a gentle curve, and is smoothly introduced into the lane 6a in a substantially horizontal posture.

  In FIG. 2C, the other lane 6b is also provided with a tape support portion 15b similar to the lane 6a. However, an attachment 16 that extends the length in the horizontal direction, that is, the support length for supporting the carrier tape 4b from below, is attached to the tape support portion 15b, and the carrier tapes 4a and 4b are viewed from below between the lanes 6a and 6b. There is a difference in support length to support. Thereby, in the carrier tape 4a introduced into the lane 6a and the carrier tape 4b introduced into the lane 6b, the carrier tapes 4a and 4b are different from each other because a change occurs in the position where the posture change to the horizontal posture is started. The posture will be changed by drawing a curve.

  Accordingly, even if there is no apparent difference in the carrier tapes 4a, 4b themselves, the carrier tapes 4a, 4b introduced from the reels 8 positioned below to the lanes 6a, 6b positioned above are drawn. Since the curves are different, it can be easily identified at a glance which carrier tape 4a, 4b. This eliminates the need to check the carrier tapes 4a and 4b between the lanes 6a and 6b and the reel 8 when performing the electronic component confirmation work, thereby shortening the time for the confirmation work.

  The attachment 16 is intended to extend the support length, and the material and shape of the attachment 16 are not limited to specific ones, but can be easily formed by bending a plate-like metal or resin. The attachment 16 that can be manufactured is detachably attached by a fixing means such as a screw 17 and can be attached to any of the tape support portions 15a and 15b. Furthermore, the attachment 16 can be made unnecessary by providing a difference in the lengths of the tape support portions 15a and 15b themselves.

  According to the present invention, since there is a difference in the carrier tape support length for each lane into which a plurality of carrier tapes are introduced into the tape feeding portion, the carrier tape is introduced into each lane located above from each reel located below. The advantage is that the carrier tape itself can be easily identified at a glance even if there is no apparent difference in the carrier tape itself due to the difference in the curves drawn by each carrier tape. And is useful in the field of electronic component mounting that receives supply of electronic components using a tape feeder.
