AI Technical Summary

Technical Problem

In the existing technology, the installation accuracy of the insulating ring and the weak conductor ring of the power battery cover plate depends on the operator's manual alignment. Affected by visual errors and fatigue, the consistency of repeated positioning is poor, resulting in low production efficiency and unstable product quality.

Method used

Design an auxiliary tooling for assembling power battery cover plates, including positioning holes, a first mounting hole and a second mounting hole. Positioning is achieved by cooperating with the edge of the substrate and the position of the explosion-proof valve, ensuring the accurate positioning and stable installation of the insulating ring and the weak guide ring, and simplifying the inspection process.

Benefits of technology

This technology enables precise positioning of the insulating ring and the weak conductive ring, improving production efficiency, ensuring product quality, eliminating the need for subsequent testing procedures, and increasing product yield.
