The second lead 4b is cut by the edge of the portion 19b. Further, by moving the first movable unit 17a and the second movable unit 17b outward, the first lead 4a and the second lead 4b remaining after cutting are clinched outward. As a result, the two leads 4a and 4b are bent outward.

In this way, when performing the first operation and the second operation, the movable units 17a and 17b are continuously moving between the first position and the second position. That is, the control device 80 performs control (two-position control) that causes the movable units 17a, 17b to wait only at two positions, the first position and the second position.

Although the present invention has been described above with reference to the first embodiment described above, the present invention is not limited to the first embodiment described above. For example, in the first embodiment, a case has been described in which the clinch units 15a, 15b cut the lower ends of the leads 4a, 4b, and bend and clinch the remaining leads 4a, 4b. However, the present invention is not limited to such a case. . Instead of inserting the leads 4a, 4b into the fixed units 18a, 18b and cutting the lower ends, the leads 4a, 4b may be simply bent and clinched by moving the movable units 17a, 17b.

Furthermore, in the component mounting apparatus 1, the configurations of the board positioning section 11, the insertion head moving device 12, the insertion head 13, and the clinch unit moving device 14 are merely examples, and other configurations may be adopted.

Further, although an example has been described in which the clinch portions 20 and 21 are formed to be inclined with respect to the direction in which the leads 4a and 4b extend (vertical direction), the present invention is not limited thereto. The clinch parts 20 and 21 may be formed in the direction in which the leads 4a and 4b extend (vertical direction). This also allows the clinch parts 20 and 21 to clinch and cut the leads 4a and 4b.

Further, although an example has been described in which the insertion portions 19a and 19b are formed to extend vertically in a cylindrical shape and have an opening on the upper surface, the present invention is not limited thereto. The insertion portions 19a and 19b do not need to be formed in a cylindrical shape. The upper end portions of the insertion portions 19a, 19b may be cut downward, for example, on the side surfaces of the insertion portions 19a, 19b along the sliding direction of the movable units 17a, 17b. That is, the insertion portions 19a, 19b may be formed in a U-shape when viewed from the horizontal direction orthogonal to the sliding direction of the movable units 17a, 17b.

The outer bending clinch portion 21a and the inner bending clinch portion 21b are held by a pair of holding portions that are arranged to face each other in a direction intersecting the direction in which the leads 4a and 4b are lined up. As a result, the clinch parts 20a, 20b of the first movable unit 17a and the clinch parts 21a, 21b of the second movable unit 17b are each held by a pair of holding parts, so that the leads 4a, 4b can be held more securely. can clinch. Moreover, the strength of the movable units 17a, 17b can be further improved.

Although an example has been described in which the clinch parts 20 and 21 are configured to slide, for example, horizontally in the direction in which the leads 4a and 4b are lined up, the present invention is not limited thereto. The clinch parts 20 and 21 may slide in a direction that is inclined to a horizontal plane in the direction in which the leads 4a and 4b are lined up. Moreover, the clinch parts 20 and 21 may be configured to swing around a swing axis. For example, the clinch parts 20 and 21 may be configured to move in a substantially horizontal arc in a portion where the leads 4a and 4b are clinched.

Further, although an example has been described in which the control device 80 selectively performs the first action and the second action by controlling the piston 16a, the control device 80 selectively performs the first action and the second action. It is not limited to this, as long as it can be implemented. The control device 80 may selectively perform the first operation and the second operation by driving a motor as the drive device 16, for example.

Further, although the control device 80 controls the drive device 16 to perform the first operation and the second operation alternately, the control device 80 controls the drive device 16 to perform either the first operation or the second operation. The drive device 16 may be controlled so that the operations are performed continuously.

In addition, when performing the first operation, the component 2 is, for example, an axial component, and when performing the second operation, the component 2 is, for example, a radial component. Other parts may be used as long as they have leads 4a and 4b.

Further, although it has been described that the first movable unit 17a and the second movable unit 17b move symmetrically with respect to the center position between the first lead 4a and the second lead 4b, the present invention is not limited thereto. The first movable unit 17a and the second movable unit 17b may move asymmetrically with respect to the center position between the first lead 4a and the second lead 4b.

In addition, although the first and second clinch units 15a and 15b each have movable units 17a and 17b that clinch the leads 4a and 4b protruding from the lower surface side of the substrate 3 (FIG. 1), the present invention is not limited to this.
