Description

Technical Field

[0001] This application relates to the field of fingerprint FPC mounting technology, and more specifically, to a fixture for optimizing fingerprint SMT mounting yield. Background Technology

[0002] Currently, in conventional fingerprint FPC mounting processes, the FPC panel is first placed on an SMT carrier board (magnetic carrier board), and then a magnetic steel sheet is pressed onto the FPC panel to fix it in place. This method has the following disadvantages:

[0003] ① Manual alignment of FPC positioning holes, carrier plate positioning holes, and magnetic steel sheet positioning holes is inaccurate and inefficient;

[0004] ② Small magnets are embedded in the carrier board, which, together with magnetic steel sheets, fix the FPC panels. When manual operation is improper or the alignment is off, the panels need to be disassembled and re-aligned, which seriously affects production efficiency.

[0005] Based on this, this application designs a fixture to optimize the yield of fingerprint SMT board mounting, which can improve alignment accuracy and increase production efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model is to improve the alignment accuracy of SMT carrier board, FPC panel and magnetic steel sheet in the fingerprint FPC board manufacturing process, and improve production efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides a fixture for optimizing the yield of fingerprint SMT boards, which adopts the following technical solution:

[0008] The device includes a square alignment fixture. The front of the alignment fixture has a fixed positioning post and four movable positioning posts. The fixed positioning post is located at one corner of the alignment fixture, and the four movable positioning posts are respectively located on the four sides of the alignment fixture and can move along the direction of their respective sides.

[0009] Furthermore, the alignment fixture is provided with sliding grooves on all four sides, and the sliding grooves are slidably provided with moving components, and the moving positioning column is fixedly mounted on the moving components.

[0010] Furthermore, the cross-section of the groove is L-shaped, with one end opening on the front of the alignment fixture and the other end opening on the side of the alignment fixture.

[0011] Furthermore, the movable component includes a movable block and a fastening screw. The movable block is slidably disposed in the slide groove, and its front side is connected to the movable positioning post. The fastening screw extends into the side opening of the slide groove and is threadedly connected to the side of the movable block.

[0012] When the position of the movable positioning column needs to be adjusted, loosen the fastening screws, and the moving block can drive the movable positioning column to move along the slide groove; when the position of the movable positioning column needs to be fixed, tighten the fastening screws.

[0013] Furthermore, the diameter of the nut of the fastening screw is larger than the diameter of the side opening of the slide groove to ensure that the fastening screw will not enter the slide groove.

[0014] Furthermore, the movable block is L-shaped and matches the shape of the groove.

[0015] Furthermore, the side length of the movable block is less than the side depth of the slide groove, ensuring that the fastening screw can be connected to the movable block and fixed to the side wall of the alignment fixture.

[0016] Compared with the prior art, the present invention has the following main advantages:

[0017] This invention uses a fixed positioning post and four adjustable movable positioning posts on the front of the alignment fixture to accommodate more panel sizes. By positioning the FPC positioning holes, carrier plate positioning holes, and magnetic steel sheet positioning holes with the positioning posts, alignment accuracy can be improved, production efficiency and product yield can be increased.
