[0001] The utility model relates to the technical field of circuit board processing, in particular to a punching processing auxiliary tool for an FPC circuit board. Background Art

[0002] With the rapid development of the information society, people's demand for electronic products is increasing, especially mobile phones and computers, which has increased the demand for FPC circuit boards, an important component of mobile phones. FPC circuit boards are also called soft circuit boards or flexible circuit boards. They are made of polyimide or polyester film as a substrate. They are highly reliable and extremely flexible printed circuit boards. They are highly favored for their high wiring density, light weight, thin thickness, good bending properties and other excellent characteristics. They can embed circuit designs on bendable and thin plastic sheets, so that a large number of precision components can be stacked in narrow and limited spaces, thus forming bendable flexible circuits.

[0003] After searching, the existing Chinese patent publication number is: CN213462508U, which provides a clamping and fixing device for circuit board production, including a support arm, and a rotating column is bolted to the left end of the support arm. The clamping and fixing device of this patent has the advantage of being able to adjust the clamping and fixing angle according to the specific size of the circuit board to form a stable clamping and fixing, replacing manual holding or fixing with certain tools, making the production process faster and more convenient, and worthy of popularization and use.

[0004] Although the above patent can adjust the clamping and fixing angle according to the specific size of the circuit board to form the advantage of stable clamping and fixing, instead of manual holding or fixing with certain tools, the above-mentioned clamping and fixing device for circuit board production still has the following problems: it does not have the cleaning function of punching waste. If the waste is not cleaned in time, it will cause the waste to accumulate in the equipment, increase the wear and damage of equipment parts, reduce the service life of the equipment, and increase the equipment maintenance cost.

[0005] In view of the above problems, a punching auxiliary tool for FPC circuit boards is proposed. Utility Model Content

[0017] As a further description of the above technical solution: an L-shaped support frame is fixed on the top of the two fixed plates, and a downward pressure cylinder is fixed on the top of the two L-shaped support frames.

[0018] By adopting the above technical solution, by installing an L-shaped support frame on the top of the fixed plate, additional support and stability can be provided to ensure that the downward pressure cylinder can accurately apply the required pressure.

[0019] As a further description of the above technical solution: the output ends of the two downward-pressing cylinders are both passed through the L-shaped support frame and are fixed with driving plugs, and the bottom ends of the driving plugs are both fixed with clamping plates.
