[0002] The coating machine is a device used to evenly coat liquid or slurry materials on the surface of a substrate. It is widely used in electronics, optics, packaging, textiles and other fields. The coating machine can accurately coat liquid or slurry materials on the substrate to ensure the thickness and uniformity of the coating and meet the quality requirements of the product. Modern coating machines usually support a variety of coating methods, such as blade coating, roller coating, spraying, etc., and can handle different types of coatings and substrates, and adapt to a variety of production processes. Since the coating machine in the related technology uses manual feeding, uneven feeding is prone to occur, resulting in problems affecting the thickness and consistency of the coating.
