<正> It is very important to locate batteries accurately and quickly during automatic battery production. Unstable or inaccurate location will negatively influence battery's consistency, quality and finished product rate. A traditional way is using sensor to detect and locate batteries directly, but because of the detecting tolerance, setting them on a fixed point exactly is almost impossible. This problem could be completely solved by the application of mint drive automatic accurate servo locating system. Firstly operating software WorkBench test was applied to collocate the servo locating driver for a most optimized control. Then based on the requirement of real location, program and test the locating action with a programming software and finally upload all the locating information to MicroLogix 1200 PLC, the PLC will control the running on each station telling when to locate, where is the location and how to eliminate bad parts. For this intelligent servo locating system has the advantages of powerful function, simple operation, high controlling and locating accuracy and easy maintenance, it is very suitable to be adopted by automatic battery making line. It is regarded as a very advanced method of control currently for reducing waste material due to inaccurate location and tough adjustment.
