A battery detection device for a winding machine

Abstract

The invention relates to a battery cell detection device of a winding machine and a detection method of the battery cell. The battery cell detection device comprises a pole piece CCD detection mechanism, a transverse pushing mechanism, a short circuit detection mechanism, a clamping jaw moving mechanism, a tab CCD detection mechanism, a waste collecting mechanism and a main controller, wherein thepole piece CCD detection mechanism is arranged on the front side of a winding machine panel. The battery cell detection device has the following functions of detecting the distance between the edge of an anode piece and the edge of an cathode piece, detecting the overlapping degree of two diaphragms, detecting whether the edges of the two electrodes and the edges of the two diaphragms are overlapped, detecting the fact whether the battery cell is short circuit, detecting the pole ear edge distance and detecting the center distance of the two pole lugs. The battery cell can be placed into different waste boxes to be stored according to the detection result. The battery cell detection device has advantages that the detection speed is high, the overall structural design is reasonable, the reworking is facilitated, the product quality is improved, and the market demand is met.

Description

technical field [0001] The invention relates to the field of winding machines, in particular to a battery detection device and a detection method of the winding machine. Background technique [0002] The winding machine is a machine that winds and combines the anode and cathode pieces that have been welded with tabs and two layers of diaphragms to form a bare cell. The cells produced by the winding machine are subsequently placed in different testing devices to detect each Whether the item parameters meet the design tolerance value, such as the distance between the edge of the anode sheet and the edge of the cathode sheet, the degree of overlap between the two diaphragms, whether the edges of the two pole sheets and the edges of the two diaphragms overlap, etc. Different items are tested in the process, the turnover and transportation of the battery cells will waste manpower and material resources, which will have a certain impact on the processing efficiency, and there are ...
