Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a clinching device for clinching lead wires of electronic components inserted into holes in a substrate.

[Conventional technology]

In recent years, with the trend toward lighter, thinner, and smaller devices, there has been a demand for higher density mounting of electronic components on boards. As a current mounting device for electronic components with lead wires, a clinch device that clinches the lead wires on the back side of a board is used.

A conventional clinching device is shown in FIG. FIG. 2 is a sectional side view of a main part of a conventional clinch device. The configuration of the clinch device shown in FIG. 2 is as follows. That is,
Reference numeral 50 designates a fixing plate, which includes a spindle shaft 51 that slides up and down on the fixing plate 50, a clinch jig base 52 attached to the upper end of the spindle shaft 51, pivot shafts 56 and 54 fixed to the clinch jig base 52, and a pivot shaft. 56.5
Clinch pieces 41°42 that swing around 4,
A roller 55 fixed to the lower end of the clinch pieces 41 and 42.
56. A cone shaft 57° that slides up and down in the spindle shaft 51 is made up of a tension coil spring 58 that always applies a biasing force to the rollers 55 and 56 toward the cone shaft 57 in response to the movement of the cone shaft 57.

The effect will be explained.

When the lead wires 11, 12 of the electronic component 1 are inserted into the board 20 which is positioned and fixed by a certain positioning means, the clinch device corresponding to the electronic component 1 is activated. That is, the spindle shaft 51 is aligned with the cone shaft 5 with respect to the fixed plate 50.
7, the tip of the clinch piece 41 and 42 is on the board 2.
0, and then the cone shaft 570゛ rises by a certain amount, so the tapered part at the tip of the cone shaft 57 pushes the rollers 55, 56 to the left and right, so the clinch pieces 41, 42 become pivot shafts. By turning in the directions of arrows 59 and 60 about 56 and 54, the upper ends of the clinch pieces 41 and 42 are connected to the lead wires 11 and 11 of the electronic component 1.
12 is clinched inward, and the electronic component 1 is fixed to the substrate 20. When the clinch of the lead wire is completed in this way, the cone shaft 57 is lowered by a certain distance that is higher than the spindle shaft 51, and the rollers 55 and 56 are attached to the tapered tip of the cone shaft 57 due to the tension coil spring 58. By following this and closing, the clinch device rotates in the opposite direction around the pivot shafts 53 and 54, and the upper ends of the clinch pieces 41 and 42 are separated from the lead wire, and then the spindle shaft 51 and the cone shaft 57 are lowered together, so that the clinch device is Return to initial position.

[Problem that the invention seeks to solve]

In conventional clinch devices, the area occupied by each clinch device for each electronic component is extremely large compared to the size of the electronic component, so it is not possible to place a clinch device under the board for each electronic component. It is possible to use a completely separate work station or a completely separate electronic component insertion clinch to clinch the leads of electronic components with completely different lead geometries or to clinch the leads of nearby electronic components. I needed equipment. Clinch frames also required high precision and were complex and expensive. The present invention solves the above-mentioned conventional problems and provides a lynch device which has a simple structure and is inexpensive so that electronic components having lead wires can be mounted at high density and can be lynched.

[Means for solving problems]

Clinch pieces are individually arranged to correspond to lead wires of a plurality of electronic components inserted into the board holes, the plurality of clinch pieces are fixed by one fixing means, and the fixing member is driven by a driving means. Accordingly, the plurality of clinch pieces are simultaneously driven to clinch the lead wires.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

An embodiment of the invention is shown in FIG. FIG. 1 is a sectional view of a main part of an embodiment of the present invention. Its configuration will be explained.

1.2.6 are each electronic components; each electronic component 1.2,
B has lead wires 11, 12, 21, 22, 61, 62, and is inserted into the board 20. The clinch device is as follows. In other words, the pace plate 7 has the pillar 8,
It has a plate plate 10 fixed via 9, and a substrate positioning bin 16 for positioning the substrate 20 is provided on the plate plate 10. Further, a slider fixing part 14 is fixed to the pace plate 7, and a jig plate 16 is fixed to the slider movable part 15 on the slider fixing part 14. On the jig plate 16, there are lead wires 11. each electronic component 1.2° wide.
Clinch pieces 4.5.6 that match the shapes of 12, 2j, and 22.61.62 are fixed. The pace plate 7 also has a jig cylinder 17 for moving the jig plate 16 left and right.
．． 18 and jig cylinders 17, 18 are each fixed with a neutral positioning block 19 for securing the jig plate 16 in a neutral position when the jig cylinders 17 and 18 are not in operation. 26 is a spring member.

The effect will be explained.

Normally, as shown in FIG. 1, the jig plate 16 is connected to the board 20 which is positioned on the plate board 10 by the board positioning pins 13, and the leads of the electronic components 1, 2 and B are connected by the spring member 26 of the neutral positioning block 19, respectively. Line 11.12.21.2
2.31.62 Force 5 is stopped at the neutral position where insertion is possible. Each electronic component 1.2, lead wire 11.12.21.
After inserting 22.61.62 into the hole of the board 2Q, first, when compressed air is flowed into the jig cylinder 17, the jig cylinder 17
The cylinder pops out in the direction of arrow 24, and the jig plate 16 to which the clinch piece 4.5.6, which matches the shape of the lead wire, is fixed, and the slider movable part 15 are slid together by a certain amount to the right. .5.6 clinch the lead wires 12, 22.62 to the right. When the compressed air is stopped, the jig plate 16 returns to the neutral position. Next, when compressed air flows into the jig cylinder 18, the jig cylinder 1
8 pops out in the direction of the arrow 25 and the jig plate 16 slides a certain amount to the left together with the slider movable part 15, so the clinch piece 4.5.6 is connected to the lead wire 11.21.
．． Clinch 61 to the left. When the compressed air is stopped, the jig plate 16 returns to the neutral position together with the slider movable part 15. In this way, electronic components 1 and 2, lead wire 1 of
1.12.21.22.31.62 is bent as shown by the dotted line and the clinch is completed.

〔Effect of the invention〕

As is clear from the above embodiments, according to the present invention, the area occupied by the clinch pieces is extremely small because the clinch pieces do not have individual driving means unlike the conventional clinch pieces, and a plurality of clinch pieces suitable for lead wires of a plurality of electronic components can be used. The plurality of clinch pieces can be simultaneously driven in one direction by one driving means to clinch the lead wires of a plurality of electronic components at once. Alternatively, the clinching of the lead wires may be repeated every time another electronic component is inserted.

The clinching device of the present invention can easily handle the clinching of the lead wires of multiple electronic components by a robot with an ATC while the position of the board is fixed. It can also handle lead line clinch. Both external bending and internal bending of the lead wire are possible, and the shape of the clinch piece is simple, so the clinch piece can be made at a significantly lower cost.Not only can we provide a low-cost clinch device with a simple structure, but it also allows for high-density mounting on the board. The effect, such as becoming possible, is a dog.
