A fixture device for pressing PCB

Abstract

The invention discloses a PCB stitching clamp device, which comprises a main body block, cooperation blocks, a fixation block, L-shaped supports and nuts. The main body block is in T shape; the two cooperation blocks are symmetrically arranged at the two sides of the main body block; the main body block and the cooperation blocks are fixedly connected through the fixation block; an L-shaped sliding channel is formed between the main body block and the cooperation blocks; the sliding channel can accommodate the plurality of L-shaped supports; the vertical length and horizontal length of the L-shaped supports are larger than the vertical length and horizontal length of the sliding channel; each L-shaped support is formed by integrating a cuboid at one end and a cylinder body with a thread atthe other end; and the L-shaped supports are in thread connection cooperation alignment with a PCB stitching area through the nuts. The PCB stitching clamp device can cooperatively stitch PCBs in various different lengths and widths, different component positions and different stitching areas by adjusting the position and quantity of the L-shaped supports, is good in clamping effect, is simple instructure, is clever in design, saves materials and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of fixtures in the production process of electronic products, in particular to a fixture device for pressing PCBs. Background technique [0002] The press-fit PCB fixture is used to place a PCB in the early stage. It is required that the surface of the fixture has high and low surfaces. The high surface supports the press-fit FPC area of ​​the PCB without components, and the low surface is used to avoid the component area. After the PCB board is fixed, the operating machine passes two probes to align the alignment MARK PAD on the PCB, and then lowers the cutter head to press the FPC and PCB together. Since the PCB has different lengths and widths, and the component areas are different, the position and length of the FPC pressing area are also different. In this way, a set of corresponding pressing fixtures need to be prepared every time a different model is made, which increases the cost of materials and pr...

Problems solved by technology

Since the PCB has different lengths and widths, and the component areas are different, the position and length of the FPC pressing area are also different. In this way, a set of corresponding pressing fixtures need to be prepared every time a different model is made, which increases the cost of materials and production cost etc.
