The Control System Desing Of Coating Equipment For Lithium-ion Battery Pole Piece

Battery control technology is one of the key technical steps of battery production,needle special requirements for different customers,we need to design a set of modular,serialization,and can be combined flexibly according to the user demand,low cost,good product quality and the production efficiency control system of lithium battery coating machine high.In this paper,firstly,describes the background,research of lithium battery pole piece coating machine.The significance of the study and progress of coating machine at home and abroad,based on the next step detailed design provides the overall coating machine.Then,the structure of the coating system is designed,including the unwinding mechanism,the coating floating roller tension mechanism,the coating mechanism,the drying system,the belt floating roller tension mechanism and the winding mechanism.Secondly,in the design of the control system of the lithium battery pole piece coating control device,with the help of digital signal processor and PLC as the core control technology and CAN bus communication technology.Analysis of lithium battery pole piece coating of the device structure and the overall control scheme,emphatically elaborated the drying temperature control and automatic pole plate rectification control design scheme,after the completion of the pole piece coating device control module hardware design,based on the design of each function device to carry out the function of software.Including the input signal and output signal processing software,oven drying temperature control software,pole piece coating deviation control software,synchronization control software development,etc..Carry out the analysis of the relevant characteristics,through the study of error correction control,synchronization control and oven temperature control analysis,the system can be a very good practical work.In the coating process,the drying temperature and the control of the coating position have a great relationship with the coating quality.The more mature technology is to control the placement of the base material,the traction and the winding motor through the appropriate control technology in the whole operation process.
