Description

TECHNICAL FIELD

[0001] The utility model belongs to coating production technical field especially relates to a die lip cleaning device and coating equipment. BACKGROUND

[0002] In the process of battery production, coating process is mainly used to uniformly coat active material (such as positive and negative electrode material) on the current collector (such as copper foil, aluminum foil) of the battery to form an electrode layer. The commonly used coating machine at present is a slot die coater, and the principle of slot die coating is to pump a certain amount of fluid into a die that can uniformly spread the fluid, i.e. a slot die. In this process, the fluid is extruded and sprayed along the gap of the coating die under a certain pressure and flow rate, and is transferred to the substrate.

[0003] A common abnormality in the slot die coating process is the appearance of a line on the pole piece, which is caused by unfiltered particles or dry slurry accumulated in the die lip, which is stuck in the die lip along with the flow of coating slurry, causing the slurry at the stuck position to be unable to be normally discharged, thereby forming a line on the pole piece film surface. The line will affect the performance of the subsequent battery capacity, charge and discharge efficiency, etc.
