Semi-automatic laminating method of electrical core of power battery and laminating equipment thereof

Abstract

The invention relates to a semi-automatic laminating method of an electrical core of a power battery and laminating equipment thereof. The method comprises the following steps: (1) stretching a diaphragm on the base layer; (2) laminating a first cathode piece; (3) winding a diaphragm on the first layer; (4) laminating a first anode piece; (5) winding a diaphragm on the second layer; (6) cyclicallyoperating step (2) to step (5) until the numbers of the laminated pieces and the wound diaphragms reach the set numbers of pieces and layers; and (7) taking out the laminated electrical core, whereinstep (3) and step (5) are carried out in an automatic mode, and other steps are carried out in a manual mode. A diaphragm winding component of the equipment controls a servo motor through a pedal switch, and controls the positioning of a diaphragm winding roller through a photoelectricity eye sensitive film; manual sucking discs at the left side and the right side suck pole pieces in a cathode piece box and an anode piece box at the left side and the right side by the vacuum generated by a vacuum valve through a vacuum sucking plate, and the pole pieces are laminated on the surfaces of the diaphragms which are wound to finish laminating; and then, the diaphragm winding component winds to the same side to automatically wind the diaphragms on the surfaces of the pole pieces. The invention can enable the diaphragms to be basically controlled in constant tension, relieve the operating strength, is convenient for replacing models and reduces the equipment cost.

Description

technical field [0001] The invention relates to a battery lamination method and equipment, in particular to a semi-automatic lamination method and lamination equipment for power battery chips. Background technique [0002] There are two methods for the production of power battery cells: one is fully manual, which involves manually stacking the cathode and anode sheets and manually winding the diaphragm; the other is fully automatic, including automatically stacking the cathode and anode sheets , Automatic winding and unwinding of the diaphragm, automatic outer winding of the diaphragm and automatic gluing. With the fully manual stacking method, the diaphragm has no tension, the stacked cells are in the shape of tiles, the diaphragms on both sides are not folded properly, and the operation intensity is high; the automatic stacking method is adopted, the equipment cost is high, and the assembly and adjustment skills are high. , and when changing the cell model, it needs to be...
