AI Technical Summary
In the existing technology, during vacuum adsorption fixation, the FPC curved surface and the sealing surface do not fit tightly, resulting in air leakage. The local adsorption force decreases, causing micro-movement of the material. In particular, it causes hole displacement and deformation during the stamping moment, and the springback after punching causes hole distortion.
A guiding fixture mechanism is adopted, including a guiding component, a limiting component, and a rubber frame. The FPC is stably fixed by the cooperation of the guide plate, rubber pad, and fixing component, ensuring that the material is not easily displaced during the punching process. A lifting mechanism is used to lift the guide plate and rubber pad to ensure punching accuracy.
It effectively solves the problems of hole position displacement and deformation caused by vacuum adsorption fixation, improves the accuracy and stability of punching, and reduces hole position distortion.
