Lithium battery pole piece coating equipment capable of preventing non-uniform coating on two sides

Abstract

The invention discloses lithium battery pole piece coating equipment capable of preventing non-uniform coating on two sides, and belongs to the technical field of lithium battery processing equipment. The lithium battery pole piece coating equipment comprises a base, the outer wall of the left side of the top of the base is fixedly connected with a discharging roller, a coating roller is arranged on the outer wall of the right side of a brush roller, and a blocking device is arranged on the outer wall of the bottom of the coating roller. A conveying device is arranged in an inner cavity of a rack and located below the blocking device. The device is limited by two sets of baffles, so that the extending positions of raw materials coated on a lithium battery pole piece towards the front side and the rear side are fixed, and the situation that the raw materials extend towards the front side and the rear side, so that the raw materials are coated on areas, not needing to be coated, of the surface of the lithium battery pole piece is avoided; and the raw materials are prevented from extending on the lithium battery pole piece, so that the probability that the front side and the rear side of the raw material coated on the outer wall of the lithium battery pole piece are uneven is reduced, the raw materials are prevented from extending, the thicknesses of the raw materials coated on the outer wall of the lithium battery pole piece are the same, and the use performance of the blocking device is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing equipment, in particular to a lithium battery pole piece coating equipment capable of preventing uneven coating on both sides. Background technique [0002] When coating the lithium battery pole piece, the raw material is coated on the outer wall of the lithium battery pole piece by the rotation of the coating roller, but the coating roller will exert a squeeze on the raw material during the coating process of the raw material Force, so that the raw material is extended and evenly coated on the pole piece of the lithium battery. Because the raw material used for coating is fluid, and the coating roller will exert pressure on the raw material, the front and rear sides of the raw material coated on the lithium battery pole piece are still It will continue to extend, causing the raw material to be applied to the area that does not need to be coated on the surface of the lithium bat...

[0002] When coating the lithium battery pole piece, the raw material is coated on the outer wall of the lithium battery pole piece by the rotation of the coating roller, but the coating roller will exert a squeeze on the raw material during the coating process of the raw material Force, so that the raw material is extended and evenly coated on the pole piece of the lithium battery. Because the raw material used for coating is fluid, and the coating roller will exert pressure on the raw material, the front and rear sides of the raw material coated on the lithium battery pole piece are still It will continue to extend, causing the raw material to be applied to the area that does not need to be coated on the surface of the lithium battery pole piece, and the extension of the raw material will cause irregularities on both sides of the raw material after coating, and will also increase the thickness of the edge of the coated raw material. Thinning will affect the quality of lithium battery pole piece processing. Therefore, we propose a lithium battery pole piece coating equipment that can prevent uneven coating on both sides
