Abstract:Based on 8bit enhanced 51 microcontroller technology, aiming at performance parameters of commonly used disc button battery, automated detection system was designed. The detection system was consisted of three parts as a feeding device, detection device and splicing device, with automatic feeding, testing, waste discharge, and splice detection functions, and realtime parameters display through LCD12864 LCD screen. The failure rate of the battery detection process is reduced, and the drawbacks of manual inspection are eliminated.
