电池极片载切机的功能是将锂电池的电池极片裁切整齐。本文所设计的电池极片载切机主要由上料系统,送料系统,裁切系统和下料系统共四个主要系统构成。电池极片载切机中的上料系统主要负责将电池极片毛坯运送到电池极片载切机的加工传递的最初位置,进而可以使送料系统接收到所上料的毛坯部件。电池极片载切机中的送料系统负责将被上料系统送来的极片部件毛坯进一步运送到裁切系统位置,以供电池极片载切机对部件毛坯进行裁切作业。电池极片载切机中的裁切系统负责完成对被送料系统送来的电池极片部件毛坯完成裁切加工,完成部件材料由毛坯转变为成型部件的加工过程。电池极片载切机中的下料系统负责将裁剪完成的工件送离裁剪系统位置,从而完成下料过程。
