AI Technical Summary

Technical Problem

Existing testing fixtures for automotive electronic products require multiple clamping and releasing operations during the testing process, making it difficult to achieve continuity of testing and accuracy of positioning.

Method used

A test fixture was designed, comprising a housing, a motor, a screw, a moving plate, a connecting plate, a connecting column, and a U-shaped clamping plate. The motor drives the screw to rotate, which in turn causes the moving plate to move the connecting plate and the connecting column. The guide effect of the inclined and straight grooves is used to achieve automatic clamping and loosening of the product. Combined with a conveyor belt assembly, the product is continuously transported.

Benefits of technology

It enables automatic clamping and releasing of automotive electronic products during the testing process, ensuring the continuity of testing work and improving the accuracy of product positioning and testing precision.
