针对块状锂电池电芯电极装配时，电芯电极装配定位不准确、效率低、安全性不高等问题，研究锂电池电芯电极的装配要点和生产特征，设计一种电芯电极装配工艺流程和与之相匹配的执行机械结构，并结合现场总线网络通信技术，设计出电芯电极装配控制系统。从机械结构方面入手着重探讨电芯电极装配的电芯翻面供给结构、方位矫正与传输机构、多工位移送结构、电芯电极装配结构、绝缘纸粘贴结构和下料结构的六级联动装置，再基于西门子PLC搭建通信网络拓扑结构，设计出控制程序算法步骤实现零件自动上料、电芯电极的自动装配及自动移送和下料过程，并建立电芯电极装配全过程、可视化的在线管理系统。该电芯电极自动装配控制系统已经在锂电池生产企业中得到应用，经济效益明显。
Design and implementation of an automatic assembly system for lithium battery cell electrodes
In response to the problems of inaccurate positioning,low efficiency,and low safety during the assembly of battery cell electrodes in block lithium batteries,the assembly elements and production characteristics of lithium battery cell electrodes were studied.A cell electrode assembly process flow and matching execution mechanical structure were proposed,and fieldbus network communication technology was combined to design a cell electrode assembly control system.The six level linkage device of the cell flip supply structure,orientation correction and transmission mechanism,multi work displacement feeding structure,cell elec-trode assembly structure,insulation paper pasting structure,and cutting structure in the assembly of cell electrodes was focused from the perspective of mechanical structure.Then,based on Siemens PLC,a communication network topology structure was con-structed,and control program algorithm steps were designed to achieve automatic feeding of parts,automatic assembly,automatic transfer,and cutting process of cell electrodes.A visual online management system for the entire process of cell electrode assem-bly was established.The automatic assembly control system for battery cell electrodes has been applied in lithium battery produc-tion enterprises,with significant economic benefits.
