AI Technical Summary

Technical Problem

In existing chip packaging processes, the casing is not fixed stably, which leads to misalignment between the flywire and the pins, affecting the packaging quality.

Method used

The system employs a bevel gear transmission system that combines a fixed plate and a suction cup with a motor drive. The suction cup secures the chip housing, while the motor drives the main bevel gear to rotate, which in turn drives the auxiliary bevel gear and the internal threaded cylinder. The lead screw moves to clamp the four corners of the housing, achieving stable fixation.

Benefits of technology

This improves the stability of the chip casing, avoids wire connection deviations caused by unstable air pressure, and ensures packaging quality.
