AI Technical Summary

Technical Problem

In battery production, the slightly damp state of silicon-carbon anode sheets can easily cause roller sticking, leading to quality defects in the coated sheets and affecting production yield.

Method used

A cleaning device was designed, including an upper scraper assembly, a dust removal device, a wiping roller assembly, and a lower scraper assembly, which are arranged sequentially along the circumference of the roller body. The roller body surface is cleaned through the blade edge, the dust suction port, and the wiping surface. It is used in conjunction with the coating head to achieve effective cleaning of the electrode sheets.

Benefits of technology

It significantly improves the problem of sticking to the rollers of electrodes in a slightly wet state, reduces defects, improves battery production yield, and has a lower cost.
