1、CCD visual inspection is used to judge whether the positive and negative poles of the battery cell are reversed, whether the battery cell position is misplaced, and whether the battery pack is reversed. The output result is given to the alarm.The output result is given to an alarm. 2、The automatic assembly line is added to automatically detect the positive and negative poles of the cell combination when the battery pack flows to the detection range of the equipment.The detection speed is high,the efficiency is high and the labor is greatly saved. 3、High definition 20 megapixel fixed focus lens, the maximum detection range of the equipment is 500 mm x 350 mm, the detection performance is stable and the efficiency is high. 4、The programming is simple, the judgment standard can be set according to the different combination mode of the cell, and countless groups of programming files can be stored.
