Embodiment

[0042] Please combine figure 1 , the embodiment of the present application provides a device 100 for removing large particles on the film surface, including: a bottom roller mechanism 10, a scraping roller mechanism 20 and a driving mechanism 30;

[0043] The bottom roller mechanism 10 is used to pull the diaphragm 200, and the output end of the drive mechanism 30 is connected to the scraping roller mechanism 20 and can drive the scraping roller mechanism 20 close to the bottom roller mechanism 10, so that the scraping roller 21 of the scraping roller mechanism 20 and the bottom roller mechanism 10 The spacing of the bottom rollers 11 is smaller than the particle diameter of the large particles. It should be noted that since the gap is very small, it appears that the scraping roller 21 and the bottom roller 11 are in contact in the figure, but in operation, there is a gap between the two. figure 1 The diaphragm 200 in the figure only shows its winding path, which does not mea...

Abstract

The invention provides a device for removing large particles on a membrane surface and membrane coating equipment, and relates to the technical field of battery production. The device for removing large particles on the membrane surface comprises a bottom roller mechanism, a scraping roller mechanism and a driving mechanism. The bottom roller mechanism is used for pulling a membrane, the output end of the driving mechanism is connected with the scraping roller mechanism and can drive the scraping roller mechanism to get close to the bottom roller mechanism, so that the distance between a scraping roller of the scraping roller mechanism and a bottom roller of the bottom roller mechanism is smaller than the particle size of the large particles. The membrane coating equipment comprises a coating device, a winding device and the device for removing large particles on the membrane surface. The device for removing large particles on the membrane surface removes the large particles so that the coated membrane is not punctured by the large particles after use in making a battery. The service life and safety of the battery are prevented from being affected. The membrane coating equipment can carry out large particle cutting on the coating, and the coating quality is guaranteed.

Description

technical field [0001] The application relates to the technical field of battery production, in particular, to a device for removing large particles on a membrane surface and diaphragm coating equipment. Background technique [0002] During the production of the coating process, large particles and PVDF aggregates will be produced or dropped, existing on the surface of the coating film, the height is higher than the normal spraying point, and its particle size is above 40um. When used at the battery end, large particles may puncture the diaphragm. It will cause a short circuit of the battery and affect the service life and safety of the battery. Contents of the invention [0003] The purpose of this application is to provide a device for removing large particles on the membrane surface, which can be used to remove large particles on the coating film, so as to prevent the large particles from affecting the life and safety of the battery. [0004] Another object of the pres...
