Design And Implementation Of Automatic Battery Electrode Group Production Machine Control System

With the development of science and technology, lead-acid batteries gradually become themovable core energy of the electrical equipment. Lead-acid battery industry has entered a stage ofrapid development. Because of the gradual reduction of global oil resources and seriousenvironmental pollution which from oil and related industries, lead-acid batteries are greatlyconcerned. As lead-acid battery is a kind of green sources which has a high environmentalperformance, lead-acid battery production process has also got a rapid development.At present, in our country battery electrode group production can be produced by manually,semi-automatic battery electrode group production machine and full-automatic battery electrodegroup production machine. The first two have low productivity, low quality and non-compliancewith environmental requirements and other shortcomings. Full-automatic battery electrode groupproduction machine is the direction of future battery production machine for it requires less manualparticipation, having high automation degree, efficient productivity and enjoys environmentalhigher safety and more reliable. The main task of this paper is to develop a new control system ofthe full-automatic battery electrode group production machine. This paper includes the followingcontents:(1) Applies the distributed control system architecture to the control system of thefull-automatic battery electrode group production machine. Each control node of the distributedcontrol system links through the CAN bus, and there is a master control node to control the all slavecontrol nodes through the CAN bus.(2) Supports industrial touch screen. The user can control the machine via the touch screen.The master control node communicates with industrial touch screen via RS485bus, and cananalysis protocol of touch screen, responsive the commands of touch screen.(3) The STM32microcontroller as the MCU of each control node, to achieve control of thesystem in a timely manner, to complete the important task of stepping motor subdivision algorithm,CAN communication, etc.(4) Achieves the fault alarm and fault localization of the full-automatic battery electrode groupproduction machine on line.(5) Achieves the mechanical actions synchronization between all slave control nodes, producesthe battery electrode group high efficiently and high stably.Automatic battery electrode group production machine control system designed in this papereasy to install on the machine, and the amount of wiring only six. The system is stable and reliable, beautiful touch screen interface, controlling functional fully, easy to use and so on. The system hasalready begun mass production. In a year’s work in some battery manufacturers, The control systemhas a pass rate of98%with more productive than manually three times. We have achieved theexpected goals successfully.
