Rolling device, the inner bottom end surface of the casing is fixedly connected with a fixing device, and the inside and left of the casing is provided with an impurity removal device, and the winding device includes a three-phase motor, a screw and a movable frame, and the three-phase The end of the main shaft of the motor is fixedly connected with a screw, the outer side of the screw is provided with a movable frame, the inner side of the right end surface of the casing is fixedly connected with a first motor, the end of the main shaft of the first motor is fixedly connected with a turntable, and the turntable The inner side of the screw mechanism is provided with draw-in grooves arranged at uniform intervals. In the present invention, through the set screw, latch, turntable and reel, the structure of the screw mechanism is compact and reliable. Combined to make its rotation more stable, which can effectively improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of impurity removal equipment, in particular to an impurity removal device for lithium-ion battery diaphragm winding. Background technique [0002] The ion conductivity of the battery separator is directly related to the overall performance of the battery. Its function of isolating the positive and negative electrodes can limit the increase in current when the battery is overcharged or the temperature rises, preventing the battery from short-circuiting and causing an explosion. It plays a role of safety protection for battery users and equipment. It is inevitable that there will be dust pollution in the process of making battery diaphragms. Dust pollution will affect the normal use of subsequent battery diaphragms. Therefore, for a lithium-ion There is a growing need for trash removal devices for battery separator winding. [0003] Most of the impurity removal devices for lithium-ion battery diaphragm windi...

AI Technical Summary

Problems solved by technology

[0003] Most of the impurity removal devices for lithium-ion battery diaphragm winding in the market currently have poor cleaning effect, and the winding drum cannot be replaced automatically, which will affect the winding effect. The traditional lithium-ion battery diaphragm winding use impurity removal device, Most of them clean the battery diaphragm continuously. When there is less dust on the surface of the battery diaphragm, the continuous use of the cleaning device will not only cause energy waste, but also easily pollute the clean diaphragm surface. Therefore, a lithium-ion battery diaphragm roll is proposed to solve the above problems. Removal of impurities
