Description

TECHNICAL FIELD

[0001] The utility model relates to the manufacturing field of circuit, specifically point to a kind of soft and hard board compression fixture. BACKGROUND

[0002] The birth and development of FPC (Flexible Printed Circuit) and PCB (Printed Circuit Board) have given birth to a new product, the soft and hard combination board. Therefore, the soft and hard combination board is a circuit board with the characteristics of FPC and PCB, which is formed by combining flexible printed circuit board and rigid printed circuit board through compression and other processes according to relevant process requirements. The existing soft and hard board includes two hard boards and a soft board area connected between the two hard boards. Each hard board is composed of a lower hard board and an upper hard board. The end of the soft board area is compressed between the lower hard board and the upper hard board. The soft board area is formed by stacking multiple layers of soft boards on top of each other. The lengths of the layers of soft boards in the existing soft board area are consistent. However, after bending the layers of soft boards, there will be a gap between the two adjacent layers of soft boards. In order to eliminate the gap between the two adjacent layers of soft boards, soft boards with different lengths must be stacked on top of each other, and the lengths of the layers of soft boards must be stacked from short to long from bottom to top. The existing soft board and hard board are compressed using a compression fixture during compression. The compression fixture is mainly composed of an upper compression fixture and a lower compression fixture. The bottom surface of the upper compression fixture is a complete plane. However, the lengths of the layers of soft boards are stacked from short to long from bottom to top. After compression by the compression fixture, the soft board will arch upward. The existing upper compression fixture does not provide space for the upward arching part of the soft board. Therefore, the existing compression fixture cannot achieve the compression of multiple layers of soft boards with different lengths and hard boards. SUMMARY

[0005] A soft and hard board compression fixture includes an openable and closable lower compression fixture and an upper compression fixture. The bottom of the upper compression fixture is provided with an upward extending avoidance space. The lower compression fixture is provided with a plurality of fixture pins. The top of the fixture pin extends into the upper compression fixture.

[0006] Further, the lower compression fixture includes a compression bottom plate, a fixture bottom plate, a first lower compression auxiliary material, a lower compression steel plate and a second lower compression auxiliary material stacked from bottom to top. The bottom of the fixture pin is arranged on the fixture bottom plate. The fixture pin penetrates through the first lower compression auxiliary material, the lower compression steel plate and the second lower compression auxiliary material.

[0007] Further, the upper pressing jig comprises a pressing cover plate, a jig cover plate, a first upper pressing auxiliary material, an upper pressing steel plate and a second upper pressing auxiliary material which are stacked from top to bottom in sequence, the first upper pressing auxiliary material, the upper pressing steel plate and the second upper pressing auxiliary material are hollow structures, the hollow parts of the first upper pressing auxiliary material, the upper pressing steel plate and the second upper pressing auxiliary material constitute the avoiding space, and the jig pins pass through the second upper pressing auxiliary material, the upper pressing steel plate, the first upper pressing auxiliary material and the jig cover plate.

[0008] Further, the jig pins are provided with four, and the four jig pins are distributed in a quadrilateral shape.

[0009] As can be seen from the above description of the utility model, compared with the prior art, the utility model has the following advantages: first, the lower hard plate of the two hard plates is placed on the top of the lower pressing jig, then the soft plates on the lower hard plate are stacked from bottom to top according to length from short to long, then the upper hard plate of the two hard plates is placed on the uppermost soft plate, then the upper pressing jig and the lower pressing jig are pressed to make the hard plate and the soft plate press-formed, and the middle part of the soft plate area is arched, the avoiding space provides space for the arching of the middle part of the soft plate area, so that the middle part of the soft plate area is not pressed after arching, and the gap between the two adjacent soft plates after bending is ensured.
