AI Technical Summary

Technical Problem

In the existing battery pack frame welding process, due to factors such as processing errors and deformation, it is difficult to accurately align the weld edges of the two half-frames, resulting in unreliable welding quality.

Method used

The two half-frames are clamped using a battery pack frame clamping fixture. The welding edges are joined together by a moving drive device, and the welding edge position is fixed by a cylinder and a clamping mechanism to ensure precise welding.

Benefits of technology

This improved welding quality and efficiency, ensured proper weld joints, and increased the product qualification rate.
