A continuous cleaning device for lithium battery electrode sheets

Abstract

The invention discloses a continuous cleaning device of a lithium battery electrode plate. The device comprises a left rotary wheel and a right rotary wheel, wherein the left rotary wheel and the right rotary wheel are axially symmetrical, the center of the left rotary wheel and the center of the right rotary wheel are fixedly provided with rotary shafts respectively, the rotary shafts are driven by a stepping motor, the section of the left rotary wheel and the section of the right rotary wheel are of a regular octagon shape, the outer walls of the left rotary wheel and the outer walls of the right rotary wheel are fixedly provided with vacuum absorbing plates, gaps are reserved between the opposite vacuum absorbing plates on the left rotary wheel and the right rotary wheel, thrust cylinders are arranged between the outer walls of the right rotary wheel and the vacuum absorbing plates, the outer side faces of the vacuum absorbing plates of the outer walls of the right rotary wheel are provided with contact sensors, the outer side faces of the vacuum absorbing plates of the outer walls of the left rotary wheel and the inner walls of the right rotary wheel are provided with photoelectric sensors, the inside of the right rotary wheel is provided with shielding plates used for shielding the photoelectric sensor at the topmost end and on the inner wall of the left side of the right rotary wheel, and an electrode plate cleaning mechanism is arranged below the vacuum absorbing plates at the bottommost end of the left rotary wheel and at the bottommost end of the right rotary wheel. The continuous cleaning device has the advantages of achieving continuous electrode plate cleaning, being high in cleaning efficiency and thorough in cleaning, preventing falling dust from causing secondary pollution to the electrode plate and the like.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a continuous cleaning device for lithium battery electrode sheets. Background technique [0002] During the production process of lithium-ion batteries, after the battery pole pieces are rolled and punched, the surface will be covered with dust and metal debris. These pole powders, metal debris and strip-shaped pole piece debris cannot be removed, which will cause serious internal short circuits to the assembled battery, which will lead to an increase in the self-discharge rate of the battery and even cause safety hazards. Therefore, during the manufacturing and processing of lithium batteries, metal shavings and dust need to be strictly controlled, especially dust with a diameter of 8um or more to avoid short circuits inside the battery. [0003] The traditional way of cleaning the pole pieces is manual brushing, but the efficiency of manual brushing is extremely low, and the dust is not ea...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing pole piece cleaning device has poor cleaning effect, and the dust falling during the cleaning process is easy to adhere to the conveyor belt, causing secondary pollution to the pole piece and affecting the cleaning effect, and provides a simple structure , easy to use, high cleaning efficiency, good cleaning effect, can effectively prevent the dust falling during the cleaning process from easily adhering to the conveyor belt, thereby causing secondary pollution to the electrode sheet of the lithium battery continuous cleaning device
