[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

The invention discloses a lithium battery pole piece coating equipment capable of preventing uneven coating on both sides in the technical field of lithium battery processing equipment. The side outer wall is provided with a coating roller, the outer wall of the bottom of the coating roller is provided with a blocking device, and the inner cavity of the frame is provided with a transmission device, and the transmission device is located below the blocking device, and the device is restricted by two sets of baffles, so that The position where the raw material coated on the lithium battery pole piece extends to the front and back sides is fixed, so as to prevent the raw material from extending to the front and rear sides, causing the raw material to be coated on the surface of the lithium battery pole piece that does not need to be coated, and to prevent the raw material from being deposited on the lithium battery. The extension on the pole piece reduces the probability of unevenness on the front and rear sides of the raw material coated on the outer wall of the lithium battery pole piece, and prevents the extension of the raw material so that the thickness of the raw material coated on the outer wall of the lithium battery pole piece is the same, increasing the use of blocking devices performance.
