Description

Technical Field

[0001] The utility model relates to the field of 3C lithium-ion battery production, in particular to a Y-shaped tab stripping and shaping device for composite foil welding. Background Art

[0002] In the 3C lithium battery industry, the traditional welding method of the welding and winding machine is single-layer foil welding, that is, the single-layer pole ear is directly welded with the single-layer foil through an ultrasonic welding machine. In order to improve the safety performance of the battery cell, composite foils are gradually introduced into the 3C lithium battery industry. Due to the differences in the structure of composite foils, the welding process requirements have also changed accordingly. The traditional single-layer foil welding is to weld the pole ear and the foil together through an ultrasonic welding machine, while the composite foil welding is to peel the pole ear and the protective sheet apart, insert and clamp the foil, and then weld the pole ear, protective sheet and the upper and lower surfaces of the foil together through an ultrasonic welding machine. At present, the pole ear and the protective sheet used for composite foil welding have been welded together in advance during the material production to form a Y-shaped pole ear. After cutting, the opening size of the Y-shaped pole ear is irregular, resulting in the inability to stably insert and clamp the composite foil when the pole ear is sent for welding. The existing welding and winding machine cannot shape and peel the pole ear in this form and send the pole piece for welding. Therefore, at present, it can only be manually peeled off the pole ear and inserted into the foil for welding, and there is no automatic implementation method. It can be seen that the traditional welding method can no longer meet the demand, and it is necessary to develop an automated device that is compatible with composite foil welding on the existing welding and winding machine.
