In addition, for easy understanding, the drawings schematically show the respective constituent elements.

FIG. 1 is a side view showing an electronic component holding device 10 according to an embodiment of the present invention. As shown in FIG. 1 , the electronic component holding device 10 is a holding device for an electronic component 40 with wires. The electronic component with lead (hereinafter also simply referred to as “electronic component”) 40 is a radial lead type electronic component including a main body portion 41 and a lead wire 42 connected in the radial direction of the main body portion 41 . Here, the electronic component 40 is an aluminum electrolytic capacitor, and two lead wires 42 are connected to the main body portion 41 .

The electronic component holding device 10 includes a base portion 20 , a holding portion 21 provided on the base portion 20 , a guide portion 22 provided on the holding portion 21 , and the control device 14 .

The base portion 20 is provided with an actuator (not shown) that extends in the Y-axis direction and drives the holding portion 21 inside.

The holding portion 21 is configured to hold the main body portion 41 of the electronic component 40 . The holding portion 21 has a pair of holding members 23 configured to hold the main body portion 41 of the electronic component 40 from both sides. The pair of holding members 23 are driven by the actuators of the base 20 to approach or separate from each other in the Y-axis direction (hereinafter also referred to as "holding direction"). The gripping member 23 has a contact surface 23 a abutting the upper side surface of the main body 41 of the electronic component 40 , and a contact surface 23 b abutting the lower side surface of the main body 41 of the electronic component 40 . Each of the four contact surfaces 23 a and 23 b is inclined with respect to a surface (XZ plane) perpendicular to the holding direction (Y-axis direction) of the holding member 23 . FIG. 2(A) is a cross-sectional view taken along the line A-A of the holding portion 21 (a pair of holding members 23 ) of FIG. 1 . As shown in FIG. 2(A) , the main body portion 41 of the electronic component 40 has a substantially cylindrical shape, and both side surfaces of the upper side of the main body portion 41 are held in contact with the contact surfaces 23 a of the pair of holding members 23 .

The guide portion 22 supports the lead wire 42 of the electronic component 40 held by the holding portion 21 . The guide portion 22 is integrally formed at the front end of one of the pair of grip members 23 (refer to FIG. 1 ). FIG. 2(B) is a cross-sectional view taken along the line B-B of the guide portion 22 of FIG. 1 . As shown in FIG. 2(B) , on the guide portion 22 , two grooves 22 a are provided so that the two wires 42 (intermediate portion) of the electronic component 40 are fitted.

The control device 14 controls the operation of the actuator that drives the holding portion 21 . Moreover, in this embodiment, the electronic component holding apparatus 10 further has the moving means 13 which can move the base part 20 relatively with respect to a board|substrate (not shown). The moving means 13 is, for example, a robot arm configured to be movable relative to the base, and the base 20 is attached to the front end of the robot arm. The control device 14 is configured to also control the motion of the robot arm. Thereby, the electronic component holding apparatus 10 of the present embodiment transfers the electronic component 40 while holding the electronic component 40, and can mount the electronic component 40 on the substrate by being mounted on the mounting position of the substrate (not shown).

Next, the operation of the electronic component holding device 10 will be described. Before the operation of the electronic component holding device 10, the lead wire 42 of each electronic component 40 is cut to a predetermined length by an electronic component supply device (not shown), and then the electronic component 40 is placed at a predetermined position, for example, on the main body portion. 41 is up and the lead wire 42 is down in the state of standby.

First, the control device 14 controls the operation of the base portion 20 (actuator), and preliminarily assumes a state in which the pair of holding members 23 of the holding portion 21 are separated from each other. Furthermore, the control device 14 controls the operation of the moving means 13 to move the base 20 to the vicinity of directly above the main body 41 of the electronic component 40 so that the main body 41 of the electronic component 40 is positioned between the pair of holding members 23 .

Next, as shown in FIG. 1 , the control device 14 drives the pair of holding members 23 of the holding portion 21 in the holding direction (Y-axis direction) to approach each other. Thereby, the contact surfaces 23a and 23b of the pair of grip members 23 are in contact with both side surfaces of the main body portion 41 of the electronic component 40 (see FIG. 2(A) ). The abutting surfaces 23a, 23b are inclined with respect to the plane (XZ plane) perpendicular to the gripping direction (Y-axis direction), so that only by driving the pair of gripping members 23 in the gripping direction, the pair of gripping members 23 are opposed to the guide portion 22. A force is applied to the side (positive direction of the Y-axis) of the supported wire 42 . Thereby, the main body portion 41 of the electronic component 40 is held in a state inclined with respect to the longitudinal direction of the lead wire 42 supported by the guide portion 22 . The contact point between the guide portion 22 and the middle portion of the lead wire 42 serves as a fulcrum, and the leading end of the lead wire 42 of the electronic component 40 held is difficult to bend. Thereby, the position of the leading end of the lead wire 42 is stabilized. In addition, in order to improve the stability of the leading end position of the lead wire 42, as shown in FIG. 2(B), a groove 22a is provided on the guide part 22, so the lead wire 42 of the electronic component 40 is embedded in the groove 22a, and the guide part 22 The contact point (fulcrum) with the middle portion of the lead wire 42 is difficult to shift. The electronic component 40 can be held stably with a simple structure.

As shown in FIG. 3 , the electronic component holding device 10 of the present embodiment mounts the electronic component 40 on the substrate 100 by transferring the electronic component 40 while holding it, and mounting the electronic component 40 on the mounting position of the substrate 100 . The control device 14 controls the operation of the robot arm (13) to relatively move the base 20 mounted on the front end of the robot arm (13) with respect to the substrate 100 . Since the main body of the electronic component 40 is held by the pair of holding members 23 , and the two wires 42 are supported in a stable state by the guide portion 22 , it is easy to position the front ends of the wires 42 on the via holes 100 a on the substrate 100 . (onboard position). In addition, since the lead wires 42 are not supported by the pair of holding members 23 but are only supported by the guide portion 22, interference with other adjacent components (not shown) mounted on the substrate 100 is unlikely to occur during insertion. Inserting jobs made easy.

In addition, in the electronic component holding device 10 of the present embodiment, although the contact surfaces 23a and 23b of the holding member 23 abutting on the side surface of the main body portion 41 of the electronic component 40 are inclined with respect to the surfaces perpendicular to the holding direction, the contact surfaces The junction surfaces 23a, 23b may not be inclined. For example, after the main body 41 is held by the pair of holding members 23 , the main body 41 and/or the lead wire 42 may be inclined by driving the pair of holding members 23 and/or the guide portion 22 . Thereby, the main-body part 41 of the electronic component 40 is held in the state inclined with respect to the longitudinal direction of the lead wire 42 supported by the guide part 22.

In addition, although the electronic component 40 of this embodiment is an aluminum electrolytic capacitor, it is not limited to this as long as it is an electronic component with a lead wire (radial lead type electronic component). FIG. 4 is a diagram showing another example of the operation of the electronic component holding device 10 . As shown in FIG. 4 , the electronic component 40 is a bypass capacitor, but even in this case, the electronic component 40 can be securely held in the same manner as in the present embodiment.

In addition, the electronic component holding device 10 of the present embodiment is constituted by a single-arm robot, but may be constituted by a dual-arm robot. FIG. 5 is a front view showing an example of a dual-arm robot constituting the electronic component holding device 10 . The dual-arm robot ( 10 ) includes a base 12 , and a pair of robotic arms (sometimes only described as “arms” hereinafter) 13 and 13 configured to be movable relative to the base 12 . Hereinafter, the direction in which the pair of arms (13, 13) are opened is referred to as the left-right direction, the direction parallel to the axis of the base axis is referred to as the up-down direction, and the direction orthogonal to the left-right direction and the up-down direction is referred to as the front-rear direction. On the base 12, various units of the robot such as the control device 14 are accommodated. Each arm ( 13 ) includes an arm portion 15 and a wrist portion 17 . Here, the arm (13) is constituted by a horizontal articulated arm, but may be constituted by a vertical articulated arm. In addition, the left and right arms (13, 13) may have substantially the same structure. Also, the left and right arms (13, 13) can be actuated independently or in conjunction with each other. A mechanical interface 17 a is set at the front end of the wrist 17 , so that an end effector (not shown here) can be attached.

FIG. 6 is a perspective view showing an example of the configuration of the left and right arms of the dual-arm robot ( 10 ) of FIG. 5 . An end effector 18 is mounted on the front end (mechanical interface 17 a ) of each wrist portion 17 of the left and right arms ( 13 , 13 ). Here, the configuration of the end effector 18 is the same on the left and right. Each end effector 18 has a rotation mechanism, and eight holding parts 21 are attached at equal intervals (45 degrees) in the radial direction from the center of the rotation mechanism. The end effector 18 is configured to adjust the interval between the lead wires 42 of the electronic component 40 at equal intervals while being rotated by a rotating mechanism in a state in which the electronic component 40 is held by the respective holding portions 21 . Since the structure of the holding portion 21 is simple and the operation is also simple, a plurality of holding portions 21 can be attached to each end effector 18 .

In addition, the electronic component holding device 10 of the present embodiment is constituted by a single-arm robot or a double-arm robot, but as long as the base 20 provided with the holding portion 21 can be relatively moved with respect to the substrate 100, and the holding portion 21 can move the base 20 relative to the substrate 100 The structure in which the held electronic components 40 (conductors 42 ) are positioned relative to the mounting positions (via holes) of the substrate 100 may be other devices.
