The control device 80 may perform component mounting according to a predetermined procedure based on the mounting information of the storage device by the processor executing the program stored in the memory. The control device 80 may perform component mounting by selectively performing the first operation regarding the first component 2a and the second operation regarding the second component 2b in accordance with a predetermined procedure. Specifically, the control device 80 performs the first action and the second action based on the mounting information preliminarily input to the storage device, that is, the information as to whether the part performs the first action or the part performs the second action. Components may be mounted selectively. Note that the mounting information may be stored in a server or the like, and the mounting information may be provided to the control device 80 through communication. Alternatively, the type of the component may be determined by a component determination unit such as a camera to determine whether the component is the first component 2a or the second component 2b, and the component 2 may be mounted on the board 3 based on the determined component information. .

First, the case of mounting the first component 2a on the substrate 3 (first operation) will be described.

The device 14 raises the clinch unit 15 . As a result, the two clinch portions 52 are positioned with respect to the lead 4a of the first component 2a. After that, the clinch cylinder 44 is operated to move the movable blades 68A of the two clinch portions 52 to the "cutting position". As a result, the intermediate portion of the lead 4a is sandwiched between the fixed blade 66A and the movable blade 68A (arrow F7 shown in FIG. 12(b)), the lower end of the lead 4a is partially cut, and the remaining lead 4a is cut. Clinch (FIGS. 12(a) and 13(a)). The two leads 4a are bent in an outward direction (outwardly bent state) so as to move away from each other. Thereby, the first component 2 a is fixed to the substrate 3 and the first component 2 a is mounted on the substrate 3 .

When the lead 4a is cut by the clinch portion 52, the lead 4a on the cut side falls below the clinch portion 52 as lead scraps. The falling lead scraps are guided by the lead scrap guide pipe 73 and discharged into the lead scrap collecting container 24 .

After that, the pickup claws 13a release the first component 2a, and the insertion head 13 and the clinch unit 15 move away from the component insertion position (mounting position) of the first component 2a.

Next, while describing the detailed configuration of the clinch unit 15 with reference to FIGS. 15 to 18, the case of mounting the second component 2b on the substrate 3 (second operation) will be described.

At this time, by rotating the clinch unit 15 with the rotation device 20 (FIG. 7), the first clinch portion 52A and the second clinch portion 52B are arranged along the longitudinal direction of the insertion hole 5b. Thereby, the leg portion 4b of the second component 2b to be inserted into the insertion hole 5b can be more reliably sandwiched between the first clinch portion 52A and the second clinch portion 52B.

After that, by changing the interval between the first clinch portion 52A and the second clinch portion 52B by the interval changing portion 30 (FIG. 7), as shown in FIG. The leg portion 4b of the second component 2b is sandwiched between the clinch portion 52B. After the leg portion 4b is sandwiched between the first clinch portion 52A and the second clinch portion 52B, the rotation device 20 rotates the first clinch portion 52A and the second clinch portion 52B in the R3 direction. Rotation of the first clinch portion 52A and the second clinch portion 52B twists the leg portion 4b in the R3 direction as shown in FIG. Thereby, it is possible to prevent the leg portion 4b from slipping out of the insertion hole 5b. Here, the angle θ1 at which the leg portion 4b is twisted (the rotation angle of the first clinch portion 52A and the second clinch portion 52B) is, for example, 60 degrees.

After that, the pickup claws 13 a release the grip of the component 2 , and the insertion head 13 and the clinch unit 15 move away from the component insertion position (mounting position) of the component 2 . Specifically, the clinch unit 15 is lowered by driving the clinch unit moving device 14 . After that, the other leg portion 4b is similarly twisted while being sandwiched between the first clinch portion 52A and the second clinch portion 52B.

In Embodiment 1, as shown in FIG. 16, the first clamping plate 69A and the second clamping plate 69B are provided inclined with respect to the slide direction A (movement guide 46 in FIG. 5). Further, the first clinch portion 52A moves the first clamping plate 69A in the A direction while maintaining the parallel state between the first clamping plate 69A and the second clamping plate 69B.

In Embodiment 1, the first clamping plate 69A is attached inside the fixed blade 66A (on the side of the second clinch portion 52B), and the second clamping plate 69B is attached inside the fixed blade 66B (on the side of the first clinch portion 52B). attached to the clinch portion 52A). Accordingly, the clamping plates 69A, 69B can be fixed more reliably than when the clamping plates 69A, 69B are provided on the movable blades 89A, 89B. Therefore, the leg portion 4b can be sandwiched more reliably, and force can be easily applied to the leg portion 4b.

The first clamping plate 69A is attached so as to cover the entire side surface (inner side) of the fixed blade 66A, and the second clamping plate 69B is attached so as to cover the entire side surface (inner side) of the fixed blade 66B. The clamping plates 69A and 69B prevent the cut lead scraps from entering between the first clinch portion 52A and the second clinch portion 52B and guide the lead scraps to the lead scrap guide pipe 73. FIG. The clamping plates 69A, 69B are attached to the fixed blades 66A, 66B by screws 70, for example.

The first holding plate 69A is provided so as to cover the side surface of the movable blade 89A facing the second clinch portion 52B when the movable blade 89A is moved to the cutting position. The second clamping plate 69B is provided so as to cover the side surface of the movable blade 89B facing the first clinch portion 52A when the movable blade 89B is moved to the cutting position. In Embodiment 1, the leg portion 4b is sandwiched between the first sandwiching plate 69A and the second sandwiching plate 69B with the movable blades 89A and 89B moved to the cutting position. Thereby, the clamping plates 69A, 69B sandwiching the leg portion 4b are supported by the movable blades 89A, 89B. Therefore, the leg portion 4b can be sandwiched more reliably, and force can be easily applied to the leg portion 4b.

In the second operation, the control device 80 changes the space between the first clamping plate 69A and the second clamping plate 69B by the space changing unit 30 so that the first clamping plate 69A and the second clamping plate 69B are separated from each other. The clinch unit 15 is controlled so that the leg portion 4b of the second component 2b is sandwiched between them.

The second clinch portion 52B has a second clamping plate 69B on the surface facing the first clinch portion 52A. In the second operation, the control device 80 changes the space between the first clamping plate 69A and the second clamping plate 69B by the space changing unit 30 so that the first clamping plate 69A and the second clamping plate 69B are separated from each other. The clinch unit 15 is controlled so that the leg portion 4b of the second component 2b is sandwiched between them.

Thereby, the holding plates 69A and 69B can increase the strength of the portion where the leg portion 4b is twisted. By sandwiching the leg portion 4b of the second component 2b between the first sandwiching plate 69A and the second sandwiching plate 69B, the leg portion 4b can be sandwiched more reliably, so that the leg portion 4b can be easily removed. can be twisted.

In the second operation, the control device 80 moves the second component 2b between the clinch portions 52A and 52B in a state where the center O1 of the insertion hole 5b of the substrate 3 is positioned on the rotation center axis C1 of the clinch unit. The clinch unit 15 is controlled so as to sandwich the leg portion 4b.

The leads 4a may simply be bent and clinched without cutting the lower ends of the leads 4a. The configuration in which the lead 4a is simply bent and clinched is realized by changing the shape of the tips of the fixed blades 66A and 66B and the movable blades 68A and 68B from sharp shapes (blade shapes) to rounded shapes. may

Also, although the case where the two leads 4a are bent in the direction facing each other has been described, this is not the only case, and the leads may be bent in the same direction. In this case, the configuration of the clinch portion may be changed so that the positional relationship between the fixed blade and the movable blade in one of the two clinch portions is reversed.

In addition, although the two leads 4a are bent in an outward direction (outwardly bent state) so as to move away from each other, the present invention is not limited to this. For example, the positional relationship between the fixed blade 66A and the movable blade 68A in the first clinch portion 52A is reversed, and the positional relationship between the fixed blade 66B and the movable blade 68B in the second clinch portion 52B is reversed. 52 may be modified. As a result, the two leads 4a may be bent inward toward each other (inwardly bent state).

Moreover, although the case where the 1st clinch part 52A was movable and the 2nd clinch part 52B was stationary was demonstrated, it does not restrict to such a case. The first clinch portion 52A may be fixed and the second clinch portion 52B may be movable, or both the first clinch portion 52A and the second clinch portion 52B may be movable. However, if the first clinch portion 52A arranged on the inside is movable and the second clinch portion 52B arranged on the outside is fixed, the clinch mechanism can be secured while increasing the range of motion of the first clinch portion 52A. 23 can be made smaller.

In addition, the interval changing portion 30 may have any configuration as long as the interval between the clinch portions can be changed.

Also, the configuration of the insertion head 13 and the clinch unit 15 in the component mounting apparatus 1 is an example, and other configurations may be adopted.

Also, the configuration of the rotating device 20 is an example, and other configurations may be employed as long as they are configured to rotate the first clinch portion 52A and the second clinch portion 52B.

Also, although the movable blades 68A and 68B are configured to swing with respect to the fixed blades 66A and 66B, other configurations may be adopted as long as they are configured to clinch the leads 4a of the component 2. FIG. For example, the lead 4a may be clinched by horizontally moving the movable blade with respect to the fixed blade.

Also, although the movable blades 68A and 68B are moved with respect to the fixed blades 66A and 66B to clinch the lead 4a, the fixed blades are made movable and the lead 4a is clinched by the movable blade and the movable blade. It may be a configuration.

The leg 4b is sandwiched between the first clamping plate 69A and the second clamping plate 69B with the movable blades 89A and 89B moved to the cutting position. Other configurations may be used as long as the leg portion 4b is sandwiched between them. For example, the leg portion 4b may be sandwiched between the movable blade and the movable blade or between the fixed blade and the fixed blade without the sandwiching plates 69A and 69B. This also allows the leg portion 4b to be easily twisted.

Also, although the angle θ1 at which the leg portion 4b is twisted is 60 degrees, any other angle may be used as long as the leg portion 4b can be prevented from slipping out of the substrate 3 through the insertion hole 5b. For example, the magnitude of angle θ1 is greater than 0 degrees.

Also, although the first clamping plate 69A and the second clamping plate 69B are provided inclined with respect to the slide direction A (movement guide 46 in FIG. 5), the present invention is not limited to this. The first clamping plate 69A and the second clamping plate 69B may be provided orthogonally to the slide direction A (movement guide 46 in FIG. 5).

Also, although the second component 2b has two leads (legs 4b) extending downward in a plate shape, the present invention is not limited to this. The leg portion 4b may be formed in an L shape, for example.

Moreover, although the leg portion 4b of the second component 2b is a large rectangular lead extending downward, it is not limited to this as long as it has a shape that can be held and twisted by the clinch unit 15. FIG. For example, the leg portion 4b may have a shape in which the distances from the center to the outer circumference are different in plan view.

In addition, although the insertion hole 5a is formed in a circular shape in plan view and the insertion hole 5b is formed in a rectangular shape in plan view, the insertion holes 5a and 5b may be other holes as long as they are holes into which the leads 4 can be inserted. may be in the shape of

Also, although the leads 4a of the first component 2a are clinched and the leg portions 4b of the second component 2b are twisted, the present invention is not limited to this. For example, the leads 4a of the first part 2a may be twisted and the legs 4b of the second part 2b clinched. For example, in each of the first component 2a and the second component 2b, the control device 80 controls the operation of clinching the lead 4 (lead 4a, leg 4b) and the operation of twisting the lead 4 (lead 4a, leg 4b). The control of the clinch unit 15 may be performed so that the is selectively performed.

The component body 4c is formed in a U shape when viewed from the side. The leg portion 4d extends downward from the component body 4c. The leg portion 4d is formed in a rectangular shape in plan view. The insertion hole 5 c is formed through the substrate 3 . The insertion hole 5c is formed according to the shape and size of the leg portion 4d. The insertion hole 5c is formed, for example, slightly larger than the leg portion 4d so that the leg portion 4d can be inserted therein. In Embodiment 2, the insertion hole 5c is formed in a rectangular shape in plan view.

The second clinch portion 90 will be described in detail with reference to FIGS. 19-21.

As shown in FIGS. 19 and 20, the second clinch portion 90 includes a fixed blade holding portion 91 holding a fixed blade 91a and a movable blade holding portion 55B holding a movable blade 68B. The fixed blade holding portion 91 has a base portion 91b and a pair of side plates (first side plate 93 and second side plate 94). The movable blade holding portion 55B swings in the F4 direction about the swing shaft 59B together with the movable blade 68B.

The base portion 91 b forms a base portion of the fixed blade holding portion 91 . The base 91b is attached to the second base member 53B.

As shown in FIG. 21, the first side plate 93 and the second side plate 94 are provided so as to cover the sides of the fixed blade 91a. That is, the first side plate 93 and the second side plate 94 are provided facing each other with the fixed blade 91a interposed therebetween. The first side plate 93 and the second side plate 94 are provided facing each other in a direction intersecting the swing plane on which the movable blade 68B swings. Here, the swing plane indicates a plane including the direction (F4) in which the movable blade 68B swings.

The first side plate 93 extends upward from a portion of the base portion 91b and covers the entire one side surface (outer side surface) of the fixed blade 91a. The first side plate 93 is configured integrally with the base portion 91b. The second side plate 94 corresponds to the second holding plate 69B in Embodiment 1, and covers the entire other side surface (inner side surface) of the fixed blade 91a.

The upper surfaces of the first side plate 93 and the second side plate 94 (the upper surface of the fixed blade holding portion 91) are formed at the upper end portion of the clinch mechanism 23A. Engaging portions 93a and 94a are formed on the upper surfaces of the first side plate 93 and the second side plate 94, respectively.

The engaging portions 93a and 94a are portions into which the leg portions 4d (FIG. 22) of the second component 2c are inserted. The engaging portions 93a, 94a apply torque (torsion moment) to the leg portion 4d of the second component 2c. Specifically, the engaging portions 93a and 94a apply torque to the leg portion 4d by applying force in the rotational direction to at least one longitudinal end side of the leg portion 4d. In the second embodiment, the engaging portions 93a and 94a apply torque to the leg portion 4d by applying force in the rotational direction to one longitudinal end side and the other longitudinal end side of the leg portion 4d.

The engaging portions 93a and 94a are opened upward. That is, the engaging portions 93a and 94a open toward the insertion hole 5c formed in the substrate 3 (FIG. 22). The engaging portions 93a and 94a are grooves (slots), for example.

The engaging portion 93a and the engaging portion 94a are provided to face each other across the movable region (space S1) of the movable blade 68B. That is, the engaging portions 93a and 94a are formed in portions facing the space S1.

The engaging portions 93a and 94a are formed near the rotation center axis C1 (FIG. 9) of the clinch mechanism 23A. Thereby, the leg portion 4d (FIG. 21) can be twisted near the center of rotation of the clinch mechanism 23A. In Embodiment 2, the engaging portions 93a and 94a are formed in the vicinity of the movable blade 68B side end portion of the fixed blade 91a.

Next, the mounting operation by the clinch mechanism 23A of Embodiment 2 will be described.

The control device 80 controls to selectively perform the first operation and the second operation. Here, since the first operation is the same as the first operation in the first embodiment, the explanation is omitted. In the second operation, the control device 80 holds the leg portion 4d of the second component 2c with the clinch mechanism 23A and rotates the clinch mechanism 23A with the rotating device 20 (FIG. 7) to twist the leg portion 4d. Specifically, in the second operation, the control device 80 inserts the leg portion 4d into the engaging portions 93a and 94a, and then rotates the clinch mechanism 23A with the rotating device 20 to twist the leg portion 4d.

A specific different mounting operation of the second component 2c to the board 3 will be described with reference to FIGS. FIG. 23 is a schematic perspective view of the clinch mechanism 23A during twisting operation of the second component 2c. 24 is a side view of FIG. 23; FIG. For the sake of convenience, in FIG. 23, the members located below the substrate 3 are also indicated by solid lines.

As shown in FIG. 22, the second component 2c is moved above the insertion hole 5c formed in the substrate 3 by the insertion head 13 (FIG. 1). The clinch mechanism 23A is moved below the insertion hole 5c by the clinch unit moving device 14 (Fig. 1).

22, the second clinch portion 90 is rotated by the rotating device 20 so that the engaging portions 93a and 94a are aligned along the longitudinal direction of the insertion hole 5c. As shown in FIGS. 23 and 24, the leg portion 4d of the second component 2c is inserted into the insertion hole 5c, and the leg portion 4d is arranged between the engaging portions 93a and 94a of the second clinch portion 90. .

Further, by rotating the second clinch portion 90 by the rotating device 20 (FIG. 7), the leg portion 4d is twisted with respect to the substrate 3 (insertion hole 5c) in the same manner as shown by the dotted line in FIG. . As a result, the second component 2c is mounted on the substrate 3 without falling out through the insertion hole 5c of the substrate 3 .

In Embodiment 2, it is determined whether or not the leg portion 4d of the second component 2c is normally twisted. A specific method for determining the success or failure of the twisting motion will be described with reference to FIG. 25 . FIG. 25 is a schematic diagram showing torque determination during twisting operation of the second component 2c.

In FIG. 25, the solid line shows the results when the twisting motion is successful, and the dashed line shows the results when the twisting motion fails. The horizontal axis of FIG. 25 indicates time, and the vertical axis of FIG. 25 indicates torque T generated in the rotating device 20 (θ drive motor 36). Torque T is detected by a torque detector 97 (FIG. 14). The torque detector 97 detects the torque T by, for example, measuring the current value in the θ drive motor 36 of the rotating device 20 .

After the rotation speed of the θ drive motor 36 is accelerated in the acceleration region, the rotation speed reaches a constant speed region. After that, the rotational speed is reduced in the deceleration region, and the rotation of the θ drive motor 36 stops after the elapse of time t3. The times in the acceleration region, the constant speed region, and the deceleration region are preset times, for example. In the constant speed range, the control device 80 adjusts the θ drive motor 36 so that the θ drive motor 36 rotates at a constant speed based on information detected from the θ drive motor 36 (for example, current value information). Control rotation.

For example, when the leg portion 4d is properly inserted into the engagement portions 93a and 94a, the torque T results as indicated by the solid line in FIG. For example, the torque T in the acceleration region is T1, the torque T in the constant speed region is T2, and the torque T in the deceleration region decreases with time and finally becomes zero. Here, T2 is a value larger than T1, for example.

On the other hand, for example, when the second component 2c is not properly inserted into the insertion hole 5c, or when the leg portion 4d of the second component 2c is not properly sandwiched between the engaging portions 93a and 94a, , resulting in the dashed line in FIG. For example, the torque T in the acceleration region is T1, the torque T in the constant speed region is T3, and the torque T in the deceleration region is T1. Here, T3 is a value smaller than T1, for example.

Based on the torque T, the control device 80 determines whether the twisting motion of the leg portion 4d of the second component 2c is successful or not by the determining portion 80a (FIG. 14). In Embodiment 2, the control device 80 determines whether or not the twisting motion of the leg 4d is successful based on a predetermined threshold value T0. Specifically, when the torque T is greater than the threshold value T0, the determination unit 80a determines that the twisting motion of the leg 4d of the second component 2c has succeeded. If the torque T is less than the threshold T0, it is determined that the twisting motion has failed. Here, the threshold value T0 is, for example, a value equal to or less than T1. The threshold value T0 is stored in the storage device described in the first embodiment, for example.

In Embodiment 2, the control device 80 determines whether or not the twisting motion is successful in a constant speed range. Specifically, the control device 80 determines whether or not the twisting motion is successful at a predetermined time (between t1 and t2) from the start of the twisting motion in the constant velocity region.

As shown by the solid line in FIG. 25, the torque T in the constant speed range is T2, which is greater than the threshold value T0. In this case, controller 80 determines that the twisting motion was successful. On the other hand, as indicated by the dashed line in FIG. 25, the torque T in the constant speed range is T3, which is smaller than the threshold value T0. In this case, controller 80 determines that the twisting motion has failed.

As described above, it is determined whether or not the leg portion 4d of the second component 2c is normally twisted. As a result, when the twisting operation is determined to be unsuccessful, the user can check the condition of the second component 2c and perform error handling such as replacing the component.

According to the component mounting apparatus of the second embodiment, the clinch unit 15A has the engaging portions 93a and 94a that engage with the leg portion 4d of the second component 2c in the rotational direction (R3) of the clinch unit 15A. have. In the second operation, the control device 80 inserts the leg portion 4d of the second component 2c into the engaging portions 93a and 94a, and then rotates the clinch unit 15A by the rotation device 20 to twist the leg portion 4d. It controls the rotating device 20 .

Accordingly, the leg portion 4d can be easily twisted by rotating the clinch unit 15A after inserting the leg portion 4d of the second component 2c into the engaging portions 93a and 94a of the clinch unit 15A.

The clinch unit 15A also includes a fixed blade holder 91 that holds a fixed blade 91a. The engaging portions 93a and 94a are provided on the upper surface of the fixed blade holding portion 91 of the clinch unit 15A.

Accordingly, by providing the engaging portions 93a and 94a in the fixed blade holding portion 91, the leg portion 4d to be inserted into the engaging portions 93a and 94a can be twisted in a more securely fixed state. Therefore, the leg portion 4d can be twisted more reliably.

In addition, the fixed blade holding portion 91 includes a pair of side plates 93 and 94 that face each other on the sides of the fixed blade 91a. The engaging portions 93a and 94a are provided on the pair of side plates 93 and 94, respectively.

Thus, by providing the engaging portions 93a and 94a on the pair of side plates 93 and 94 respectively, the leg portion 4d can be inserted into both the engaging portions 93a and 94a to twist both ends of the leg portion 4d. . Therefore, the leg portion 4d can be twisted more reliably.

Also, the upper surface of the fixed blade holding portion 91 is formed at the upper end portion of the clinch unit 15A.

By forming the upper surface of the fixed blade holding portion 91 at the upper end portion of the clinch unit 15A, the leg portion 4d of the second component 2c can be easily inserted into the engaging portions 93a and 94a of the fixed blade holding portion 91. be able to. Therefore, the leg portion 4d can be twisted more easily. Further, since the substrate 3 can be supported by the fixed blade holding portion 91, the lead 4a of the first component 2a can be clinched while the substrate 3 is supported by the fixed blade holding portion 91. FIG.

Further, a torque detection unit 97 for detecting the torque T generated in the rotating device 20, and a twisting operation of the leg 4d of the second component 2c in the second operation based on the torque T detected by the torque detection unit 97. A judgment unit 80a for judging success or failure is provided.

As a result, the success or failure of the twisting motion can be easily determined by determining the success or failure of the twisting motion based on the torque T generated in the rotating device 20 .

Further, when the torque T detected by the torque detection unit 97 is larger than the predetermined threshold value T0 in the second operation, the determination unit 80a determines that the twisting operation of the leg 4d of the second component 2c has succeeded. judge. If the torque T is smaller than the threshold T0, the determination unit 80a determines that the twisting motion of the leg 4d of the second component 2c has failed.

As a result, the success or failure of the twisting motion can be determined more easily by determining the success or failure of the twisting motion using the threshold value T0.

Further, in the second motion, the determination unit 80a determines whether or not the twisting motion of the leg 4d of the second component 2c is successful in the constant speed region of the rotation of the rotating device 20 .

As a result, it is possible to more easily determine the success or failure of the twisting motion by determining the success or failure of the twisting motion in the constant speed range of the rotation of the rotating device 20 .

As described above, the present disclosure has been described with reference to the above-described second embodiment, but the present disclosure is not limited to the above-described second embodiment. In the second embodiment, in the second operation, the leg 4d is twisted by rotating the clinch mechanism 23A with the rotation device 20 after inserting the leg 4d into the engaging portions 93a and 94a. not. That is, as long as the leg 4d can be twisted by holding the leg 4d with the clinch mechanism 23A and rotating the clinch mechanism 23A with the rotation device 20 in the second operation, other configurations (methods) may be used. . For example, the leg portion 4d may be twisted by applying a force in the rotational direction to one of the main surfaces of the leg portion 4d instead of twisting the leg portion 4d across the first main surface and the second main surface.

Also, although the engaging portions 93a and 94a are formed on the upper surfaces of the first side plate 93 and the second side plate 94, other configurations may be used as long as the leg portion 4d can be twisted. The engaging portions 93a and 94a may be provided on either the first side plate 93 or the second side plate 94, for example. Also, the engaging portions 93a and 94a may be provided, for example, on the movable blade 68B of the first clinch portion 52A and the second clinch portion 52B.

Further, although the torque detection unit 97 detects the torque T by measuring the current value in the θ drive motor 36 of the rotating device 20, it is limited to this if the torque T generated in the rotating device 20 can be detected. not. Torque T may be detected by, for example, a torque sensor.

In the θ drive motor 36, after the rotational speed is accelerated in the acceleration region, the rotational speed reaches the constant speed region, but the constant speed region may not exist. Also, although the control device 80 determines whether or not the twisting motion is successful in the constant velocity region, the present invention is not limited to this. The determination of success or failure of the twisting motion may be made, for example, in an acceleration region, a deceleration region, an intermediate region between the acceleration region and the deceleration region, or the like. At this time, the behavior A1 of the torque T in the twisting motion when the leg portion 4d is not inserted into the engaging portions 93a and 94a may be stored in advance in the storage portion. The determination of success or failure of the twisting motion of the leg 4d may be performed using the behavior A1. Specifically, when there is a behavior different from the behavior A1, it may be determined that the twisting motion has succeeded, and in the case of a behavior similar to the behavior A1, it may be determined that the twisting motion has failed.

Also, the magnitude relationship between the torque values T1, T2, and T3 is an example, and is not limited to the second embodiment.

Further, although the leg portion 4d of the second component 2c is formed in a rectangular shape in plan view, the shape is not limited to this as long as it can be held and twisted by the clinch unit 15A. For example, the leg portion 4d may have a shape in which the distances from the center to the outer circumference are different in plan view.

Although the present disclosure has been fully described in connection with preferred embodiments and with reference to the accompanying drawings, various variations and modifications will become apparent to those skilled in the art.
