Research on laser cutting system of high-speed and high-precision lithium battery
高速高精度锂电池极耳激光切割系统研究

摘要

传统的锂电池极耳切割采用刀模切割，刀模切割是采用纯机械结构与极片直接接触来实现的切割，在保证精度情况下，料带运行的最高速度为50m/min，此速度已经不能满足目前生产的需要。随着激光技术的发展，激光切割已经引入新能源锂电池加工领域。激光的非接触加工特性，由于市场的需要，追求高速高精度锂电池极耳切割成为研究的方向。本文是基于智鼎自动化研发的simaGJm - EtherCAT总线式激光控制器搭建的高度高精度极耳激光切割系统展开讨论，主要是对整个控制系统搭建，以180m/min切割速度时振镜运动补偿进行了研究和设计极耳切割动画演示软件。同时，讨论了系统对激光能量和频率跟随特性，并对其发展作了展望。

Abstract

With direct contact for cutting, under the condition of guaranteed accuracy, the maximum speed of the material belt operation is 50m / min, which can not meet the needs of the current production. With the development of laser technology, laser cutting has introduced new energy lithium battery processing. Laser non-contact processing characteristics, due to the needs of the market, the pursuit of high speed and high precision lithium battery pole ear cutting has become the research direction. This paper is a discussion on the high precision pole ear laser cutting system based on the simaGJm-EtherCAT bus laser controller developed by Zhiding Automation. It mainly discusses the construction of the whole control system, studies the lens motion compensation at 180m / min, and designs the pole ear cutting animation demonstration software. Both the laser energy and frequency following characteristics are discussed and its development is discussed.
