Electrode laser etching machine

Electrode laser etching machine

Equipment Introduction

This equipment is a lithium battery polar sheet narrow-width fully automatic flight wire engraving machine, which  is mainly used for the etching process of the coating of the core electrode area. It can be compatible with          continuous coating, intercoating and other coating materials. Through the continuous walking belt of pole release and winding, after correction and positioning, the double laser station continuously performs rapid burning,         gasification, expansion and peeling of the designated area of A-side and B-side active substances respectively; in  order to  remove the agreed range and depth dressing, and make it meet the requirements of etching quality and  cell performance.
