Abstract

The invention relates to a transfer positioning device and a transfer positioning method for winding-type laminated battery pole pieces. There is an adsorption device for adsorbing and fixing the battery pole pieces to be processed. The transfer and positioning device for pole pieces of wound laminated batteries, the adsorption device and the heat compound device are not in the same longitudinal plane. The vacuum suction cup, which is an adsorption device for absorbing and fixing the battery pole pieces to be processed, is provided above the conveying device, so that during the semi-hot pressing process through the semi-hot pressing device, the battery pole pieces and the diaphragm are positioned accurately, and the pole pieces will not move. If there is a size deviation, the involved laminated battery can be directly wound after the hot-compression lamination is completed, which can greatly improve the production efficiency.

Description

technical field [0001] The invention relates to a pole piece positioning and product transfer device and working method in battery production, in particular to a positioning and transfer device and working method between pole piece and viscous diaphragm in battery pole piece production. Background technique [0002] There are two main ways to make laminated batteries, stacked and wound. The stacked type mainly uses a Z-shaped stack of separators, and the positive and negative electrodes are placed in sequence. The wound-up laminated battery is to place the positive and negative electrodes on the viscous separator. On the one hand, the positive and negative plates are fixed on the viscous separator by thermal lamination. After this process is completed, direct winding can be realized, which can effectively improve production efficiency. The positive and negative electrode sheets can be a single piece after die-cutting, or a pole piece unit composed of a single piece of positi...
