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.
