[0001] This utility model relates to the field of FPC fixing technology, specifically to an FPC fixing fixture. Background Technology

[0002] FPC fixtures are auxiliary tools designed specifically for FPC processing, testing, or assembly. Their core function is to solve the problems of FPC deformation and displacement through precise positioning and stable clamping, ensuring processing accuracy and efficiency. Common types include test fixtures, surface mount fixtures, and assembly fixtures. Their advantages include improving production yield, reducing human error, and being compatible with the needs of automated production lines. They are widely used in consumer electronics, automotive electronics, and other fields, and are an indispensable precision tooling in flexible circuit board manufacturing.

[0003] In existing technologies, the adjustment of FPC fixing devices in FPC fixing fixtures is extremely inconvenient. Traditional designs often employ fixed structures or complex and cumbersome adjustment mechanisms. When fixing FPCs of different sizes and shapes, operators need to spend a lot of time disassembling, reassembling, or finely adjusting the device, which seriously affects production efficiency. Moreover, its fixing flexibility is poor and it is difficult to adapt to diverse production needs. When facing FPCs with special shapes or irregular edges, existing fixing devices cannot effectively fit, resulting in insecure fixing, affecting product quality, and becoming a major obstacle in the production process. Therefore, we need an FPC fixing fixture. Utility Model Content

A positioning hole 213 is opened on the top of the base 1. First, place the FPC on the base 1, rotate the fixing shell 208 so that it rotates 90 degrees to the appropriate position on the outer wall of the fixing rod 204, and use bolts 207 to pass through the sliding sleeve 205 and the fixing rod 204, and fix it with threads through the mounting hole 206. Then, pull the pull plate 209 upward, the spring 210 is stretched, the positioning rod 212 is separated from the positioning hole 213, the fixing shell 208 is moved left and right, and the slider 203 is moved along the slide groove 202 to the appropriate position. Finally, release the pull plate 209, the spring 210 rebounds, the pull plate 209 moves down, and the positioning rod 212 is inserted into the positioning hole 213 to complete the fixation.

After rotating to the appropriate position, the bolt 207 is threaded into the mounting hole 206, allowing the bolt 207 to pass through the sliding sleeve 205 and fix it to the fixed rod 204. After fixing, by pulling the pull plate 209 upward, the spring 210 is stretched, allowing the positioning rod 212 to move upward and separate from the positioning hole 213. Then, move the fixed shell 208 left and right, allowing the fixed shell 208 to drive the slider 203 to move left and right along the slide groove 202 inside the slide rail 201 to the appropriate position. Then, release the pull plate. 209. The spring 210 rebounds, causing the pull plate 209 to move downwards, which in turn moves the positioning rod 212 downwards. This allows the positioning rod 212 to be inserted into the positioning hole 213, thus completing the fixation. By pulling out the connecting block 302, the connecting block 302 can slide on the slide rod 301, allowing the connecting block 302 to extend and retract inside the fixed shell 208, thereby extending the length of the connecting block 302. By rotating the adjusting screw 304, the adjusting screw 304 can move downwards while rotating, which in turn moves the pressure block 305 downwards. This pressure block 305 can move the pressure pad 306 downwards, thus pressing FPCs of different sizes together.
