Abstract

The invention discloses an adsorption type winding drum and a winding device and method. The adsorption type winding drum comprises a hollow drum body with openings in the two ends, an inner cavity ofthe drum body is divided into three parts through two cavity plates, air expansion holes are formed in the two ends of the inner cavity of the drum body, an adsorption cavity is formed in the middleof the inner cavity of the drum body, each sealing adsorption opening is a duct structure in the center of each cavity plate, the air expansion holes are in communication with the adsorption cavity through the sealing adsorption openings, and a plurality of adsorption holes are formed in the surface of an outer drum body of the adsorption cavity. According to the design of the adsorption type winding drum, the bearing capacity is large, stress is uniform, the adsorption type winding drum can be widely applied to battery coating workshops and rolling slitting workshops, the wrinkling phenomenonin the winding process of lithium battery pole pieces and diaphragms can be effectively reduced, and the product rejection rate is reduced.

Description

technical field

[0001] The invention belongs to the technical field of lithium battery manufacturing, and in particular relates to a lithium battery adsorption reel, a winding device and a method. Background technique

[0002] In the production of lithium battery manufacturing, coating winding is usually to wind the tape on the reel in advance to fix the pole piece or diaphragm. The pole piece or diaphragm is prone to wrinkles during the process of sticking with the tape, and it is easy to cause wrinkles in the internal layers during continuous winding, resulting in the scrapping of the pole piece or diaphragm. In the prior art, the winding tension is mostly controlled to release the accumulated tension of the pole piece or the inner pole piece of the diaphragm during the winding process to ensure the smoothness of the winding, but the stability and effect of the winding are not good. Contents of the invention

[0003] The purpose of the present invention is to provide an...
