Battery pole piece rubberizing device

Abstract

The invention provides a battery pole piece rubberizing device which is used for rubberizing a film on the surface of a pole piece and comprises a rack, two first traction rollers which are horizontally arranged are arranged at the upper end of the rack, two second traction rollers which are horizontally arranged are arranged at the lower end of the rack, a rotationally connected pressing roller is arranged in the middle of the rack, and the pressing roller is of a hollow structure. A plurality of first negative pressure holes are formed in the outer wall of the pressing roller, a center shaft of the pressing roller is connected with a rotating connector, the rotating connector is connected with a first negative pressure pipe, a square-frame-shaped cutter attached to the edge of a rubber sheet is arranged under the pressing roller, and a top block is arranged in the cutter in a sleeved mode. According to the rubberizing device provided by the invention, continuous rubberizing work is carried out before the pole piece is slit, the pole piece is still conveyed during rubberizing, the time delayed by shutdown is reduced, and compared with a manual rubberizing mode, the rubberizing device is high in automation degree and high in rubberizing speed, the production period of a battery is shortened, and the productivity is improved.

Description

technical field [0001] The invention relates to the technical field of battery pole piece gluing equipment, in particular to a battery pole piece gluing device. Background technique [0002] With the rapid development of new energy vehicles, the demand for lithium batteries is also increasing. During the production and processing of batteries, it is necessary to stick adhesive paper on the front and back sides of the battery pole pieces. In the prior art, it is generally done manually The way of pasting the adhesive paper is to glue the battery pole pieces. The manual way of sticking the glue paper needs to cut the battery pole pieces first, and then glue them one by one. This method is extremely inefficient and affects the production cycle of lithium batteries. production capacity. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a battery pole piece gluing device to solve all or one of the problems mentioned in the b...
