Impurity removing device for rolling lithium-ion battery diaphragm

Abstract

The invention relates to the technical field of impurity removing equipment, in particular to an impurity removing device for rolling a lithium-ion battery diaphragm. The device comprises a shell, a rolling device, a fixing device and an impurity removing device. The rolling device is arranged on the right end surface of the inner side of the shell, the fixing device is fixedly connected to the bottom end surface of the inner side of the shell, the impurity removing device is arranged on the left side of the inner side of the shell, the rolling device comprises a three-phase motor, a screw anda movable rack, the tail end of a spindle of the three-phase motor is fixedly connected to the screw, the movable rack is arranged on the outer side of the screw, a first motor is fixedly connected to the inner side of the right end surface of the shell, a rotary disc is fixedly connected to the tail end of the spindle of the first motor, and slots which are uniformly formed in an equally spacedmanner are formed in the inner side of the rotary disc. By arranging the screw, plugs, the rotary disc and a rolling barrel, the screw mechanism is compact and reliable in structure. By arranging theplugs capable of being locked to the slots in the rolling barrel, the impurity removing device can rotate more stably, so that the work efficiency can be improved effectively.

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
