AI Technical Summary

Technical Problem

In the process of edge-wrapping the battery cells using traditional open-type edge-wrapping wheels, the edge-wrapping material is easily affected by volatilization, moisture absorption, and chemical reactions in the air, resulting in unstable edge-wrapping quality.

Method used

A battery cell edge coating mechanism is designed. The outer circumference of the edge-coating wheel is provided with an annular groove. Part of the annular groove accommodates the side of the battery cell. The outer shell covers the non-edge-coating area to reduce the contact between the edge-coating adhesive and air. The gap is sealed by a stop part. A cleaning rod is set to scrape off excess adhesive. The depth of the annular groove is only enough to accommodate the amount of adhesive required for a single application. The coating is applied by rotation using a drive device.

Benefits of technology

It effectively reduces the oxidation and failure of the edge-sealing adhesive, improves the edge-sealing quality, reduces production costs, reduces adhesive waste, and enhances sealing performance and coating effect.
