The plurality of holes are all horizontally closed holes, and while the plurality of leads are inserted into the plurality of holes, the control unit moves the mounting head or the lead straightening unit horizontally so that the plurality of leads abut against the end faces of the plurality of holes.

[0050] According to the second aspect of this disclosure, based on the component mounting device described in the first aspect, the plurality of holes are circular when viewed from the vertical direction.

[0051] According to the third aspect of this disclosure, based on the component mounting device described in the first or second aspect, while the plurality of leads are inserted into the plurality of holes, the control unit moves the mounting head or the lead straightening unit in a first horizontal direction and a second horizontal direction that are different from each other.

For the component determined to be without bending of the plurality of leads, the plurality of leads are not inserted into the plurality of holes, but are inserted into the insertion hole of the substrate.

[0054] According to the sixth aspect of this disclosure, based on the component mounting device described in the fifth aspect, the control unit determines the bending direction of the plurality of leads based on the captured image, and while the plurality of leads are inserted into the plurality of holes, the control unit moves the mounting head or the lead straightening unit in a horizontal direction corresponding to the bending direction of the plurality of leads.

[0061] (Implementation Method)

[0062] The embodiments will now be described with reference to the accompanying drawings.

[0063] [Overall Structure]

[0064] Figure 1 This is a schematic diagram showing a component mounting device 1 according to one embodiment of the present disclosure.

[0065] Figure 1 The component mounting device 1 shown is a device for mounting a component 60 onto a substrate 3 using a mounting head 10. The component 60 is an electronic component such as a leaded component or a chip component.

[0066] The component mounting device 1 includes a substrate transport unit 2, a component supply unit 20, a mounting head 10, a head moving device 12, a notification unit 34, and a control unit 36.

[0067] The substrate transport unit 2 is a device that moves the substrate 3 into and out of the mounting position located at the center of the base 1a. The substrate transport unit 2 moves the substrate 3, which is moved from the upstream side of the component mounting system (not shown) including the component mounting device 1, in the X direction, positions it, and holds it in the mounting position. When the component mounting operation is completed, the substrate transport unit 2 moves the substrate 3 downstream of the component mounting system.

[0068] Component supply units 20 are disposed at both ends of the base 1a in the Y direction. Component supply units 20 include a rod feeder 4, a belt feeder 5, and a tray feeder 7 as multiple component supply units. Figure 1 Multiple rod-type feeders 4 are arranged along the X direction on one side of the base 1a. Figure 1 On the other side of the base 1a, multiple belt feeders 5 are arranged along the X direction. A pallet feeder 7 with a component tray 6 is arranged side by side with the multiple belt feeders 5.

[0069] The rod-type feeder 4, belt feeder 5, and tray feeder 7, serving as the component supply unit, supply the component 60 for mounting onto the substrate 3. The component supply unit is not limited to having all of the rod-type feeders 4, belt feeders 5, and tray feeders 7; having at least one of these is sufficient, as long as the component can be supplied by any method. Figure 1 In the example, a pallet 6 of the pallet feeder 7 is configured with multiple components 60.

[0070] The head moving device 12 includes a Y-axis worktable 8 and an X-axis beam 9. The Y-axis worktable 8 has linear drive devices at both ends in the X direction on the upper surface of the base 1a. The X-axis beam 9 has the same linear drive device and is connected to the Y-axis worktable 8. A mounting head 10 capable of moving in the X direction is mounted on the X-axis beam 9. The X-axis beam 9 moves in the Y direction via the linear drive device of the Y-axis worktable 8, and the mounting head 10 moves in the X direction via the linear drive device of the X-axis beam 9.

[0071] The head moving device 12 controls the linear drive device to move the mounting head 10 to the pick-up position of the rod feeder 4, the pick-up position of the belt feeder 5, or the pick-up position of the component tray 6. The component 60 picked up by the mounting head 10 at the pick-up position is transferred and mounted to the mounting position of the substrate 3 held in the substrate transport unit 2. The component mounting device 1 repeatedly performs a series of processes from transporting the substrate 3 to mounting the component 60.

[0072] like Figure 1 As shown, a component camera 14 is provided between the substrate transport unit 2 and the component supply unit 20. The mounting head 10, from which a component has been removed from the component supply unit 20, moves upward toward the component camera 14, thereby acquiring an image of the component held on the mounting head 10. The positional shift of the component held on the mounting head 10 is detected by performing recognition processing on the acquired image.

[0073] An integrated movable substrate camera 32 is mounted on the mounting head 10. The substrate camera 32 is an imaging unit with an imaging function, mounted on the mounting head 10 with its imaging optical axis facing downwards. The substrate camera 32, for example, images the substrate 3 from below, and performs recognition processing on the captured image, thereby detecting the positional offset of the substrate 3, i.e., the positional offset of the mounting point. Furthermore, based on the aforementioned detection results of the component's positional offset and the detection results of the mounting point's positional offset, positional correction is performed during component mounting. Positional correction includes rotational alignment to ensure that the component's rotational position about the θ-axis is aligned with the correct direction.

[0074] The notification unit 34 is a component used to notify the operator of the component installation device 1. The notification unit 34 notifies the operator through any method such as screen display or voice guidance.

[0075] The control unit 36 ​​is a component that controls the various components of the component mounting device 1. The control unit 36 ​​may be, for example, a microcomputer equipped with a processor and a memory storing a computer program that can be executed by the processor.

[0076] Figure 2 This is a side view that briefly shows the state of the mounting head 10 holding the component 60.

[0077] like Figure 2 As shown, the mounting head 10 of this embodiment has a pair of clamps 50 for holding the component 60. The clamps 50 are configured to move in the horizontal direction (arrow A1) and selectively hold the component body 62 of the component 60.

[0078] In this embodiment, component 60 is a radial component with leads, having a main body 62 and a plurality of leads 64. Figure 2 The component 60 shown has two leads 64A and 64B.

[0079] Figure 3 , Figure 4 This is a simplified bottom view of component 60.

[0080] exist Figure 3 The image shows the state where leads 64A and 64B are not bent. Figure 4 The image shows that leads 64A and 64B have been bent.

[0081] exist Figure 4 In the example shown, the two leads 64A and 64B exhibit bends in different directions. At lead 64A on the left side of the paper, a bend with a -X component is produced (arrow A2). At lead 64B on the right side of the paper, a bend containing both +X and +Y components is produced (arrow A3).

[0082] The presence and direction of the bend at the lead 64 of component 60 can be based on Figure 1 The detection is performed using images captured by the camera 14 shown. As a component for correcting the bending of the lead 64 when bending is detected in the lead 64 of component 60, a [missing information - likely a component name] is provided. Figure 1 The lead wire straightening section 40 is shown.

[0083] The lead wire straightening section 40 is a component used to straighten the bending of the lead wire 64, and is provided on the base 1a. (Usage) Figure 5 The following figures illustrate the detailed structure of the lead wire straightening section 40.

[0084] Figure 5 This is a simplified top view of the lead wire straightening section 40.

[0085] Figure 5 The lead wire straightening part 40 shown includes a plate member 44 with multiple holes 42 (42A, 42B) and a support member 46.

[0086] Multiple holes 42 are used to correct the bending of the leads 64 of component 60, with one hole 42 corresponding to each lead 64. Figure 5 In the example shown, two holes 42A and 42B are provided corresponding to the two leads 64A and 64B. The center-to-center distance between holes 42A and 42B is set to approximately the same length as the distance between leads 64A and 64B. Leads 64A and 64B can be inserted into holes 42A and 42B simultaneously, respectively. Holes 42A and 42B each have end faces 43A and 43B as inner circumferential surfaces.

[0087] In this embodiment, the shapes of holes 42A and 42B when viewed from above are circular. The sizes of holes 42A and 42B are set to accommodate the maximum bending width of the inserted leads 64A and 64B.

[0088] The plate member 44 is a plate-shaped member with multiple holes 42, and two holes 42A and 42B are provided as through holes that extend through in the thickness direction.

[0089] The support member 46 is a component that supports the plate member 44 and is detachable, and is fixedly mounted on the base 1a of the component mounting device 1. By allowing the plate member 44 to be detached relative to the support member 46, plate members with different hole sizes and shapes can be installed and used in a replaceable manner.

[0090] Figure 6 This is a simplified longitudinal sectional view showing the state in which the leads 64A and 64B of the component 60 are inserted into the plurality of holes 42A and 42B of the lead wire straightening section 40.

[0091] like Figure 6 As shown, with lead wire 64A inserted into hole 42A and lead wire 64B inserted into hole 42B, the mounting head 10 of the holding member 60 is moved horizontally (arrow A4). This causes plastic deformation of lead wire 64A by pressing it against the end face 43A of hole 42A, thereby correcting the bending of lead wire 64A; similarly, plastic deformation of lead wire 64B by pressing it against the end face 43B of hole 42B causes the bending of lead wire 64B to be corrected.

[0092] use Figures 7 to 12B The method of using the component mounting device 1 with the above structure to correct the bending of the lead 64 of the component 60 and to mount the component 60 onto the substrate 3 will be described.

[0093] Figure 7 , Figure 8 This is a flowchart illustrating an example of a component mounting method performed by the component mounting device 1. Figure 7 , Figure 8 Each of the processes shown is executed by the control unit 36.

[0094] Figure 9 , Figure 10A , Figure 10B , Figure 11A , Figure 11B , Figure 12A , Figure 12B These are briefly shown. Figure 7 , Figure 8 The diagram shows the execution status of the component installation method. Figure 9 , Figure 10A , Figure 11A , Figure 12A These are longitudinal sectional views of the lead wire straightening section 40 and its surrounding area. Figure 10B , Figure 11B , Figure 12B These are bottom views of the lead wire straightening section 40 and its surrounding area.

[0095] like Figure 7 As shown, the control unit 36 ​​picks up the component 60 using the mounting head 10 (S11). Specifically, the control unit 36 ​​moves the mounting head 10 in the XY direction to the picking position of any one of the rod feeder 4, belt feeder 5, and tray feeder 7, which are component supply units 20, and uses the chuck 50 to pick up the component 60.

[0096] The control unit 36 ​​moves the mounting head 10 toward the lead identification position (S12). Specifically, the control unit 36 ​​moves the mounting head 10 holding the component 60 in the XY direction toward... Figure 1 The component shown is located directly above camera 14, where the lead wire identification position is moved.

[0097] The control unit 36 ​​identifies the bending of the lead wire 64 of the component 60 (S13). Specifically, the control unit 36 ​​takes pictures of the area containing the lead wires 64A and 64B of the component 60 using the component camera 14, and performs a prescribed image analysis on the captured images to identify the presence and direction of bending of each of the lead wires 64A and 64B.

[0098] For example, in the photos Figure 3 In the case of component 60 shown, it is identified that leads 64A and 64B are both without bending. (The image was captured...) Figure 4 In the case of component 60 shown, it is identified that there is a bend in the -X direction in lead 64A and a bend in lead 64B that includes components in the +X direction and the +Y direction.

[0099] The control unit 36 ​​determines whether the lead wire 64 is bent (S14). Specifically, the control unit 36 ​​determines whether the lead wire 64 is bent based on the identification result of the lead wire 64 in step S13. If at least one of the two leads 64A and 64B is bent, it is determined that the lead wire 64 is bent (yes in S14), and the process moves to the lead wire straightening process in steps S15 to S17. On the other hand, if neither of the two leads 64A and 64B is bent, it is determined that the lead wire 64 is not bent (no in S14), the lead wire straightening process is not performed, and the process moves to the component assembly process in steps S22 and S23, which will be described later.

[0100] When moving to the lead wire straightening process, the control unit 36 ​​moves the mounting head 10 toward the lead wire straightening position (S15). Specifically, the control unit 36 ​​moves the mounting head 10 holding the component 60 in the XY direction toward... Figure 1 The lead wire correction position is moved directly above the lead wire correction section 40 shown.

[0101] The control unit 36 ​​inserts the lead wire 64 into the hole 42 of the lead wire straightening unit 40 (S16). Specifically, as follows: Figure 9 As shown, the mounting head 10, located above the lead wire straightening section 40, is lowered in the Z direction (arrow A5), and the leads 64A and 64B of the component 60 held by the chuck 50 are inserted into the holes 42A and 42B of the lead wire straightening section 40, respectively. The XY coordinates of the lead wire straightening position are preset so that lead wire 64A is directly above hole 42A and lead wire 64B is directly above hole 42B.

[0102] The control unit 36 ​​corrects the bending of the lead wire 64 (S17). Specifically, as follows: Figure 10A , Figure 10BAs shown, with the leads 64A and 64B of component 60 inserted into holes 42A and 42B respectively, the control unit 36 ​​moves the mounting head 10 in the horizontal direction. As previously described, by pressing the leads 64A and 64B against the end faces 43A and 43B of holes 42A and 42B respectively, the leads 64A and 64B are plastically deformed, and the bending of the leads 64A and 64B can be corrected.

[0103] In this embodiment, based on the identification result in step S13, the bending direction of each of the leads 64A and 64B is determined, and the mounting head 10 is moved horizontally in the direction corresponding to the determined bending direction.

[0104] Specifically, such as Figure 11A , Figure 11B As shown, in order to correct the bending of lead 64A among the two leads 64A and 64B, the mounting head 10 is moved in the direction corresponding to the bending direction of lead 64A (-X direction) (arrow A6). As a result, lead 64A is pressed against the end face 43A of hole 42A and plastically deformed in the direction opposite to the bending direction (+X direction), thereby correcting the bending of lead 64A.

[0105] The amount of movement of the mounting head 10 can also be determined by taking into account the bending amount and springback amount of the identified lead 64A. Alternatively, it can be set to a predetermined amount regardless of the bending amount of the identified lead 64A.

[0106] When lead 64A is pressed against end face 43A of hole 42A, lead 64B may also come into contact with end face 43B of hole 42B. Compared with lead 64A, lead 64B is pressed less relative to end face 43B and is also affected by springback. Therefore, the amount of plastic deformation of lead 64B can be ignored.

[0107] Similarly, as Figure 12A , Figure 12B As shown, in order to correct the bending of lead 64B, mounting head 10 is moved in a direction corresponding to the bending direction of lead 64B (the inclined direction of +X / +Y) (arrow A7). As a result, lead 64B is pressed against the end face 43B of hole 42B and plastically deformed in the opposite direction to the bending direction (the inclined direction of -X / -Y), thereby correcting the bending of lead 64B.

[0108] The amount of movement of the mounting head 10 when correcting the bend of lead wire 64B can also be determined using the same method as when correcting the bend of lead wire 64A. In addition, the amount of plastic deformation of lead wire 64A when lead wire 64B is pressed against the end face 43B of hole 42B can be substantially ignored.

[0109] By performing the lead wire straightening process in steps S15 to S17 described above, the bending of the two leads 64A and 64B of component 60 can be corrected.

[0110] It should be noted that, for the purpose of correcting the bending of the two leads 64A and 64B, the mounting head 10 is oriented in the direction of... Figure 11A , Figure 11B Move in the first horizontal direction (arrow A6) and towards Figure 12A , Figure 12B The second horizontal direction (arrow A7) movement has been described, but it is not limited to this case. Depending on the number of leads 64 and the direction of bending, the mounting head 10 can be moved in a horizontal direction that can correct the bending of each lead 64.

[0111] When the lead wire straightening process is performed, the control unit 36 ​​raises the mounting head 10 (S18). As a result, the component 60 is disengaged from the lead wire straightening unit 40.

[0112] Similar to steps S12 to S14, control unit 36 ​​moves mounting head 10 towards lead wire identification position (S19), identifies the bending of lead wire 64 of component 60 (S20), and determines whether lead wire 64 is bent (S21). The specific operation is the same as steps S12 to S14, so the description is omitted.

[0113] If it is determined that the lead wire 64 is bent (yes in S21), the control unit 36 ​​executes the lead wire straightening process of steps S15 to S17 again. Therefore, if the bending of the lead wire 64 is not sufficiently corrected in one lead wire straightening process, a second lead wire straightening process is executed. As long as it is determined that the lead wire 64 is bent in step S21 (yes in S21), the lead wire straightening process of steps S15 to S17 is repeatedly executed. This allows for accurate and precise correction of the bending of the lead wire 64.

[0114] The amount of movement of the mounting head 10 in the subsequent lead wire straightening process can be the same as or different from the amount of movement of the mounting head 10 in the first lead wire straightening process. For example, the amount of movement in the subsequent process can be relatively larger. In addition, the direction in which the mounting head 10 is moved can be the same or different.

[0115] It should be noted that if the lead wire 64 is determined to be bent even after performing the lead wire straightening process a predetermined number of times, the operation of the component mounting device 1 can be stopped, and the notification unit 34 can issue an error notification.

[0116] If it is determined that the lead wire 64 is not bent (no in S21, no in S14), the control unit 36 ​​executes the component installation process in steps S22 and S23.

[0117] Specifically, the control unit 36 ​​moves the mounting head 10 toward the component mounting position (S22). Specifically, the control unit 36 ​​moves the mounting head 10 holding the component 60 in the XY direction toward... Figure 1 The component mounting position, directly above the substrate 3 shown, is moved.

[0118] The control unit 36 ​​inserts the lead 64 of the component 60 into the insertion hole of the substrate 3 (S23). Specifically, as follows: Figure 13A As shown, the leads 64A and 64B are inserted into the insertion holes 3A and 3B of the substrate 3 by lowering the mounting head 10 located above the substrate 3 in the Z direction (arrow A8).

[0119] In the lead wire straightening process of steps S15 to S17, the bending of lead wire 64 is corrected. Since steps S21 and S14 have confirmed that lead wire 64 is not bent, in the component assembly process, leads 64A and 64B can be inserted into insertion holes 3A and 3B with good accuracy. This reduces component assembly errors and improves assembly accuracy and productivity.

[0120] In the component mounting device 1 of this embodiment, in particular, multiple holes 42 that are closed in the horizontal direction can be used to correct the bending of multiple leads 64 at the same time, and can cope with bending in various directions, thus improving the mounting accuracy and productivity.

[0121] (Function / Effect)

[0122] As described above, the component mounting apparatus 1 of this embodiment includes: a component supply unit 20 that supplies a component 60 having a plurality of leads 64; a lead straightening unit 40 having a plurality of holes 42 respectively corresponding to the plurality of leads 64; a mounting head 10 that holds the component 60 supplied by the component supply unit 20; and a control unit 36 ​​that controls the mounting head 10 so that the mounting head 10 inserts the plurality of leads 64 of the held component 60 into the plurality of holes 42 of the lead straightening unit 40, and then inserts them into the insertion holes 3A and 3B of the substrate 3. The plurality of holes 42 are holes that are closed in the horizontal direction. While the plurality of leads 64 are inserted into the plurality of holes 42, the control unit 36 ​​moves the mounting head 10 in the horizontal direction so that the plurality of leads 64 abut against the end faces 43 of the plurality of holes 42.

[0123] With this structure, multiple holes 42 that are closed in the horizontal direction can be used to correct the bending of multiple leads 64 at the same time, and can cope with bending of the leads 64 in various directions.

[0124] Furthermore, in the component mounting device 1 of the embodiment, each of the plurality of holes 42 is circular when viewed from the vertical direction. This structure allows for bending of the lead wire 64 in various directions.

[0125] Furthermore, in the component mounting device 1 of the embodiment, while multiple leads 64 are inserted into multiple holes 42, the control unit 36 ​​directs the mounting head 10 toward different first horizontal directions ( Figure 11A , Figure 11B Arrow A6 as shown) and the second horizontal direction ( Figure 12A , Figure 12B Arrow A7 (as shown) moves. Based on this structure, it is possible to correct the bending of the lead wire 64 in multiple directions.

[0126] Furthermore, in the component mounting device 1 of the embodiment, the control unit 36 ​​moves the mounting head 10 in the horizontal direction to bring the plurality of leads 64 into contact with the end faces 43 of the plurality of holes 42. With this structure, the lead straightening unit 40 can be fixedly arranged, which simplifies the structure of the lead straightening unit 40.

[0127] Furthermore, in the component mounting apparatus 1 of the embodiment, a component camera 14 (image capture unit) is also provided to capture images of the component 60 held by the mounting head 10. Based on the images captured by the component camera 14, the control unit 36 ​​determines whether the plurality of leads 64 are bent (S13, S14), and for components 60 where it is determined that the plurality of leads 64 are not bent (not in S14), the plurality of leads 64 are not inserted into the plurality of holes 42, but are inserted into the insertion holes 3A, 3B of the substrate 3 (S22, S23). With this structure, the bending of the leads 64 can be corrected only for components 60 where it is determined that the leads 64 are bent.

[0128] Furthermore, in the component mounting apparatus 1 of the embodiment, the control unit 36 ​​determines the bending direction of the plurality of leads 64 based on the captured image taken by the component camera 14, and moves the mounting head 10 in a horizontal direction corresponding to the bending direction of the plurality of leads 64 while the plurality of leads 64 are inserted into the plurality of holes 42. With this structure, the bending of the leads 64 can be corrected with greater accuracy.

[0129] Furthermore, in the component mounting device 1 of the embodiment, the lead wire straightening part 40 includes: a plate member 44 having a plurality of holes 42; and a support member 46 that supports the plate member 44 so that it can be mounted and dismounted. With such a structure, the plate member 44 can be replaced according to the specifications of the component 60.

[0130] As described above, the component mounting method of the embodiment includes: a step of holding a component 60 having a plurality of leads 64 by a mounting head 10 (S11); a step of inserting the plurality of leads 64 of the component 60 held by the mounting head 10 into a plurality of holes 42 provided in the lead straightening part 40 (S16); and a step of inserting the plurality of leads 64 of the component 60 held by the mounting head 10 into the insertion holes 3A and 3B of the substrate 3 (S23). In the step of inserting the plurality of leads 64 into the plurality of holes 42, the mounting head 10 is moved in the horizontal direction so that the plurality of leads 64 abut against the end face 43 of the plurality of holes 42.

[0131] According to this method, multiple holes 42 that are closed in the horizontal direction can be used to correct the bending of multiple leads 64 at the same time, and can cope with bending of the leads 64 in various directions.

[0132] (other)

[0133] The present invention has been described above with reference to the embodiments described above, but the present invention is not limited to the embodiments described above. For example, in the embodiments, the case in which the lead wire straightening part 40 is fixedly arranged and the mounting head 10 is moved in the horizontal direction to perform the lead wire straightening process has been described, but the present invention is not limited to this case. For example, the lead wire straightening part 40 may be configured to be movable, and the lead wire straightening process may be performed by moving the lead wire straightening part 40 in the horizontal direction. That is, it is sufficient as long as the lead wire straightening part 40 and the mounting head 10 can move relative to each other.

[0134] Furthermore, in the embodiment, the presence and direction of bending of the lead wire 64 are identified, and the mounting head 10 is moved horizontally in a direction corresponding to the identified bending direction of the lead wire 64, but this is not a limitation. For example, the bending of the lead wire 64 may not be identified, and the mounting head 10 may be moved uniformly in a predetermined horizontal direction during the lead wire straightening process. Regarding this example, using... Figure 14A , Figure 14B Please provide an explanation.

[0135] (Variation Example 1)

[0136] Figure 14A , Figure 14B This is a longitudinal sectional view and a bottom view that briefly show the direction of movement of the mounting head 10 in the lead wire straightening process of Modified Example 1.

[0137] like Figure 14A , Figure 14BAs shown, after the mounting head 10 moves linearly in the horizontal direction (arrow B1), it moves in a rotating manner within the XY plane (arrow B2). This allows for the pressing of the leads 64A and 64B around the end faces 43A and 43B of the holes 42A and 42B, respectively, to correct any bending of the leads 64A and 64B. With this correction method, the actions of identifying the bending of the leads 64A can be omitted (S13, S14), and bending of the leads 64A and 64B in any direction can be corrected.

[0138] In the component mounting device 1 of Modified Example 1, with multiple leads 64 inserted into multiple holes 42, the control unit 36 ​​moves the mounting head 10 in a predetermined horizontal direction regardless of whether the multiple leads 64 are bent. With this structure, bending of the leads 64 can be corrected in a simpler way.

[0139] In the component mounting device 1 of Modified Example 1, with multiple leads 64 inserted into multiple holes 42, the control unit 36 ​​rotates the mounting head 10 in the horizontal plane. With this structure, bending of the leads 64 can be corrected in a simpler way.

[0140] It should be noted that the installation head 10 is not limited to rotating in the horizontal plane; it can also be moved linearly only in a predetermined horizontal direction. By moving linearly in at least a first horizontal direction and a second horizontal direction different from the first horizontal direction, correction of bends in multiple directions can be achieved.

[0141] Furthermore, in the embodiment, the case where the lead wire straightening section 40 has two holes 42A and 42B corresponding to the component 60 (radial component) having two leads 64A and 64B has been described, but it is not limited to this case. When the component 60 has three or more leads, the lead wire straightening section can be provided with a number of holes corresponding to the number of leads.

[0142] Furthermore, in this embodiment, the case where the lead wire straightening part 40 corresponds to one type of component 60 has been described, but it is not limited to this case; it may also correspond to two or more types of components 60. Regarding this example, using... Figure 15 Please provide an explanation.

[0143] (Variation Example 2)

[0144] Figure 15 This is a top view showing the lead wire straightening section 140 of Modified Example 2.

[0145] Figure 15The lead wire straightening part 140 shown has a plate member 144 and a support member 146. In the plate member 144, a plurality of first holes 42A, 42B and a plurality of second holes 142A to 142D are provided as two types of holes.

[0146] The first holes 42A and 42B (42) are holes provided corresponding to the component 60 which has two leads 64. The second holes 142A to 142D (142) are holes provided corresponding to the component (not shown) which has four leads.

[0147] By setting these two types of holes, it is possible to handle the lead wire straightening of two different components. (Not limited to...) Figure 15 The number of holes in the lead wire straightening section can be appropriately changed according to the number of leads of each of the two components, as shown in the layout.

[0148] In the component mounting device of Modified Example 2, the lead wire straightening part 140 has multiple holes, each having a plurality of first holes 42 corresponding to a plurality of leads 64 of the first component 60 and a plurality of second holes 142 corresponding to a plurality of leads of the second component. With this structure, various components can be accommodated.

[0149] Furthermore, in this embodiment, the case where the lead wire straightening section 40 can be attached to and detached from one plate member 44 has been described, but it is not limited to this case; it is also possible to attach and detach two or more plate members 44. Regarding this example, using... Figure 16 Please provide an explanation.

[0150] (Variation Example 3)

[0151] Figure 16 This is a top view showing the lead wire straightening section 240 of Modified Example 3.

[0152] Figure 16 The lead wire straightening section 240 shown has two plate members 244 and 245 and a support member 246.

[0153] In plate member 244, two first holes 242A and 242B (242) are provided corresponding to the first component having two leads. In plate member 245, two second holes 243A and 243B (243) are provided corresponding to the second component having two leads.

[0154] By configuring the two plate members 244 and 245 to be detachable relative to the support member 246, and... Figure 15 Similarly, the modified examples shown can also accommodate the lead wire correction for two different components. It should be noted that the number and configuration of the holes provided in the plate members 244 and 245 can be appropriately changed according to the number and spacing of the lead wires of the corresponding components.

[0155] according to Figure 16 The structure shown is capable of simultaneously performing the actions of straightening the leads of the first component using multiple holes 242A and 242B, and straightening the leads of the second component using multiple holes 243A and 243B. Regarding this straightening method, [the following is mentioned:] Using... Figure 17 Please provide an explanation.

[0156] Figure 17 This is a longitudinal sectional view that briefly illustrates the lead wire correction method in Modified Example 3.

[0157] exist Figure 17 In the modified example shown, the mounting head 300 has two types of clamps 350 and 351. The first clamp 350 holds the first component 360, and the second clamp 351 holds the second component 361. The first component 360 has two leads 364A and 364B (364) that insert into two holes 242A and 242B of the plate member 244. The second component 361 has two leads 365A and 365B (365) that insert into two holes 243A and 243B of the plate member 245.

[0158] exist Figure 17 In the state shown, by moving the mounting head 300, which has two clamps 350 and 351, together in the horizontal direction, the bending of the leads 364 and 365 on the two components 350 and 351 can be corrected simultaneously.

[0159] As a method of moving the mounting head 300 in this case, such as using Figure 14A , Figure 14B As explained, it can also be moved in a horizontal direction after moving in a straight line (arrow B1), and then rotated in the horizontal plane (arrow B2). With this method of movement, the mounting head 300 can be moved in a predetermined horizontal direction, thus it can accommodate bending of the lead wire in any direction and eliminates the need to identify the bending direction of the lead wire. It is suitable for simultaneously correcting bending of the lead wires of multiple components 350 and 351.

[0160] In the component mounting device of Modification 4, the mounting head 300 includes a first chuck 350 for holding a first component 360 and a second chuck 351 for holding a second component 361. When the plurality of leads 364 of the first component 360 held by the first chuck 350 are inserted into the first hole 242 and the plurality of leads 365 of the second component 361 held by the second chuck 351 are inserted into the second hole 243, the control unit 36 ​​moves the mounting head 300 in the horizontal direction.

[0161] Based on this structure, the bending of leads 364 and 365 on multiple components 360 and 361 can be corrected simultaneously, thereby further improving productivity.
