AI Technical Summary

Technical Problem

During the processing of flexible printed circuit boards, the clamping force is difficult to control, which can lead to deformation, scratches or damage, affecting electrical performance and appearance quality. At the same time, insufficient clamping force can cause shaking and displacement, reducing processing accuracy and increasing scrap rate.

Method used

A dual-axis motor drives a threaded rod to clamp the circuit board, while a pressure sensor and controller monitor the clamping force in real time to ensure appropriate clamping force. A suction cup and support plate system is designed to ensure the stability and accurate feeding of the circuit board during processing.

Benefits of technology

This technology enables stable clamping of flexible printed circuit boards during processing, preventing damage, improving processing accuracy and yield, and ensuring the integrity and positioning accuracy of the circuit boards.
