Abstract

The invention relates to the technical field of battery production, in particular to edge flanging equipment and an edge flanging method thereof. The edge flanging equipment comprises a circulating conveying device, a plurality of clamping devices and a feeding and discharging device, an edge cutting device, a first edge folding device, a second edge folding device, a hot pressing device, a thirdedge folding device and a shaping device which are sequentially arranged on the periphery of the circulating conveying device. The circulating conveying device is used for conveying the multiple clamping devices to sequentially move to the feeding and discharging device, the edge shearing device, the first edge folding device, the second edge folding device, the hot pressing device, the third edgefolding device and the shaping device. According to the invention, feeding, edge cutting, 90-degree edge folding, 180-degree edge folding, hot-pressing shaping, 270-degree edge folding, shaping and discharging of the battery are automatically realized; the battery edge folding device is high in automation degree and edge folding efficiency, labor intensity and labor cost are reduced, a battery isclamped on the clamping device all the time in the whole edge folding process, the position precision and stability of the battery are guaranteed, the edge folding precision is high, the edge foldingquality is good, and the quality of the battery after edge folding is guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to an edge folding device and an edge folding method. Background technique [0002] Lithium batteries are common small devices that provide electrical energy, and are widely used in mobile phones, laptop computers, automotive power, charging energy storage and other equipment. With the development of lithium batteries, there are more and more applications of aluminum-plastic film soft pack lithium batteries. Lithium battery folding is an important process in the production of soft-pack lithium batteries. The effect of folding is a key factor in controlling the dimensions of flexible packaging batteries. Inadequate folding will directly affect whether customers can successfully assemble the finished battery into electronic equipment products . At present, some of the existing edge folding technologies adopt the structure of upper and lower folding knives, the gap between...
