Lithium ion battery die cutting waste winding device

Abstract

The invention discloses a lithium ion battery die cutting waste winding device. Die cutting waste is wound around a winding reel (2) mounted in the middle position of the inner wall of the rear part of a box (1), a driving motor is in transmission connection with the driving end of the winding reel (2), the driving motor drives the winding reel (2) to rotate, the winding reel (2) is perpendicularto the inner wall of the rear part of the box (1), the left lower part of the winding reel (2) is provided with a passing roller (3), the passing roller (3) is perpendicular to the inner wall of the rear part of the box (1), the bottom of the box (1) is provided with a slit (4), the slit (4) is opposite to the passing roller (3), the winding reel (2), the passing roller (3) and the slit (4) are parallel to one another, a vacuum tube (6) is connected to the rear part of the box body (1), one end of the vacuum tube extends into an inner cavity of the box (1), the other end of the vacuum tube (6)is connected with a filtering tank (7), an outlet of the tail part of the filtering tank (7) is connected with a vacuumizing device, and the control end of the driving motor and the control end of the vacuumizing device are connected with a control device.

Description

technical field [0001] The invention relates to a lithium-ion battery die-cut waste winding device. Background technique [0002] Dust in the production process of lithium-ion batteries has a great influence on the performance of batteries, so it is very important to ensure that the cleanliness of the workshop environment in the production process of lithium-ion batteries meets the requirements. After the lithium-ion battery pole roll is die-cut into pole pieces, the remaining unnecessary material around it needs to be collected in a separate roll. During the winding process, particle dust will be generated at the incision of the material and due to the mutual friction between the material. Particle dust flying around not only reduces the cleanliness of the workshop, especially after falling on the surface of the normal production pole piece, it will have a serious adverse effect on the performance of the battery made in the subsequent sequence.

Problems solved by technology

After the lithium-ion battery pole roll is die-cut into pole pieces, the remaining unnecessary material around it needs to be collected in a separate roll. During the winding process, particle dust will be generated at the incision of the material and due to the mutual friction between the material. Particle dust flying around not only reduces the cleanliness of the workshop, especially after it falls on the surface of the normal production pole piece and adheres to it, it will have a serious adverse effect on the performance of the battery made in the subsequent sequence.
