AI Technical Summary

Technical Problem

Existing technology cannot effectively support the upper cover of the high-low voltage converter, resulting in poor fixing effect and affecting processing accuracy and quality.

Method used

The system employs a support and fixing assembly, including a motor-driven lead screw, a scissor arm, and a capsule. The motor drives the lead screw to rotate, and the scissor arm rotates to raise the capsule and provide downward support to the upper cover. The flexible support of the capsule also prevents deformation.

Benefits of technology

This provides stable support for the top cover, preventing deformation during processing, improving the fixing effect and processing accuracy, and ensuring the safety and quality of the components.
