Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a case crimping device, and more particularly to a case crimping device that crimps a case on which a circuit board is mounted and fixes the case to the circuit board.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, there has been known a case crimping device for crimping a case in which a circuit board is housed inside and a projecting portion is provided to fix the case to the circuit board.

FIG. 5 is a diagram for explaining the operation of a conventional case caulking device. As shown in the figure, in the case caulking device of the related art, the projecting parts 2 ₁ , 2 ₂ and 2 ₃ formed on the lower part of the side surface of the case 1 mounted on the device are arranged laterally of the case 1. , Eashi Linda caulking pin 4 ₁ which is dynamic drive in a direction substantially parallel to the circuit board 3 accommodated in the case 1 (not shown), 4 _2, 4 ₃ are pressed by caulking, the circuit board case 1 It was fixed at 3.

[0004]

[Problems to be solved by the device]

In crimping device of the conventional case is disposed in the caulking pin 4 _1, 4 _2, 4 ₃ side of the cliff over scan 1 as described above, is substantially parallel to the drive on the substrate surface as shown in FIG. However, when multiple cases are inserted in a board in which multiple circuit boards of the same configuration are arranged in a row on one board (hereinafter referred to as a continuous board), the caulking pins hit the case. Unable to use the device.

Further, if a sufficient space is provided between the cases on the connecting board so that the crimping pins do not hit the case, the case can be caulked by the conventional device, but the connecting board is essentially unnecessary space. Therefore, there is a problem that the cost of the board increases because the board must be provided. Furthermore, if a plurality of caulking pins are provided for caulking a plurality of cases that are inserted into a continuous board at the same time, there is a drawback that the device becomes large and has a very complicated structure.

In view of the above points, it is an object of the present invention to provide a caulking device for a case, which has a small and simple structure and can caulk a plurality of cases inserted in a continuous board at the same time.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a mounting part for mounting a case, a sliding part for sliding toward the mounting part, and a case mounted on the mounting part by sliding the sliding part toward the mounting part. And a bending member arranged to bend the case by pressing.

[0008]

[Action]

 According to the present invention configured as described above, the bending member acts to press the case and bend the case when the sliding portion slides toward the mounting portion.

【Example】

 1 and 2 are partially cutaway front views of an embodiment of the present invention, FIG. 3 is a perspective view of an essential part of an embodiment of the present invention, and FIG. 4 is an essential part of an embodiment of the present invention. It is an enlarged perspective view. Hereinafter, FIGS. 1 to 4 will be described.

In FIGS. 1 and 2, reference numeral 11 denotes a case caulking device. Reference numeral 12 denotes a table which is a sliding portion, and the table 12 is driven by an air cylinder 13 and slides in a vertical direction indicated by an arrow in the figure. FIG. 1 shows the state in which the table 12 has moved downward, and FIG. 2 shows the state in which the table 12 has moved upward.

In FIG. 1, a caulking pin plate 14 is detachably fixed to the upper surface of the table 12 by bolts 15 ₁ and 15 ₂ . The convex portions 16 ₁ , 16 ₂ , 16 ₃ are fixed to the upper surface of the caulking pin plate 14. Caulking pins 17 ₁ , 17 ₂ , 17 ₃ , 17 ₄ , 17 ₅ and 17 _{6 which} are bending members are screwed to the respective convex portions 16 ₁ , 16 ₂ and 16 ₃ .

On the table 12, poles 19 ₁ and 19 ₂ through which the springs 18 ₁ and 18 ₂ are inserted are provided upright. The upper portions of the poles 19 ₁ and 19 ₂ are inserted into holes (not shown) of the circuit board retainer 20.

The circuit board retainer 20 is supported by springs 18 ₁ and 18 ₂ . The circuit board retainer 20, which is a mounting portion, is provided with a pin 21 having a conical tip and cylindrical pins 22 ₁ , 22 ₂ , 22 ₃ having a flat tip.

In the state where the table 12 shown in FIG. 1 is moved downward, the continuous board 23 conveyed to the upper part of the circuit board retainer 20 by a belt conveyor (not shown) has the board surfaces as pins 22 ₁ , 2 2 ₂ and 22 ₃ . The pin 21 is inserted into a hole 24 formed in the substrate so as to be in contact with and supported, and its horizontal position is regulated. Cases 25 ₁ , 25 ₂ and 25 ₃ are inserted into holes (not shown) formed in the connecting board 23.

A lock plate 26 is detachably fixed to the upper portion of the caulking device 11 of the case with bolts 15 ₃ and 15 ₄ . A case retainer 27 is fixed to the lower surface of the lock plate 26. As shown in the drawing, the case retainer 27 has a shape capable of abutting and fixing the cases 25 ₁ , 25 ₂ , 25 ₃ .

When the table 12 is driven by the air cylinder 13 and moved upward from the state shown in FIG. 1, the circuit board retainer 20 supported by the springs 18 ₁ and 18 ₂ is attached to the continuous board 23 and the continuous board 23. It moves up together with the inserted cases 25 ₁ , 25 ₂ , 25 ₃ , and the upper parts of the cases 25 ₁ , 25 ₂ , 25 ₃ abut on the case retainer 27 and are fixedly supported.

When the table 12 is further moved up, the cases 25 ₁ , 25 ₂ , 25 ₃ are fixed to the case holder 27, and the circuit board retainer 20 holds its position, while the springs 18 ₁ , 18 ₂ move to the table. It is pressed by 12 and compressed.

As a result, the caulking pin plate 14 continues to move further upward. Convex portion 16₁, 16 ₂ , 16₃The caulking pin 17 arranged in each₁, 17₂, 17₃, 17_Four, 17 _Five , 17₆Is a hole 20 formed in the circuit board retainer 20.₁, 20₂, 20₃, 20_Four, 20_Five, 20₆The case 25 as shown in FIGS. 3 and 4 (A) and (B).₁, 25₂, 25₃28 formed on the lower part of the₁, 28₂Abutted against.

As is apparent from FIG. 4, the caulking pins 17 ₁ ... 17 ₆ have a tip end surface which is substantially perpendicular to the protrusion. The remaining portion of the tip surface, which is in contact with the projecting portion, is formed to be inclined with respect to the projecting portion. As shown in FIG. 4B, the table 12 is moved upward by contacting the projecting portion. It is configured so that the protrusion is bent by being pressed by and is crimped to the soldered portion (not shown) of the circuit board. Thus, in this embodiment, as shown in state table 12 of Figure 2 has been moved upward, the case 25 _1, 25 _2, 25 _3, respectively at the same time or occupied it is possible.

The caulking pins 17 ₁ , 17 ₂ , 17 ₃ , 17 ₄ , 17 ₅ , 17 ₆ are driven vertically by the air cylinder 12 with respect to the connecting board 23, so that the cases 25 ₁ , 25 ₂ , It is possible to arrange 25 ₃ close to each other. Therefore, the continuous board 23 can have a minimum required area, and the device can be made small and have a simple structure, so that the equipment can be constructed at low cost. ..

Further, the caulking pin plate 14 and the lock plate 26 are detachable. Therefore, the placement position of the caulking pin on the convex portion is replaced with that of the caulking pin plate that matches the placement position of the protruding portion of the case of a type different from the case shown in the above embodiment, and another type By replacing with a lock plate that matches the shape of the case, it is possible to crimp another case.

It is to be noted that the present invention is not limited to the case where the single continuous board constitutes three continuous boards as in the above embodiment. Further, the arrangement of the caulking pins (or the projecting portions) is not limited to the case where two pieces are arranged facing the side surface of the case as in the above-mentioned embodiment, and four pieces are arranged on the four side surfaces of the case. The crimping pins may be arranged so that they can be applied to.
