The coating equipment for the meniscus surface comprises a central control panel (1), a PLC control cabinet (2), a location sheet-loading table (3) for the film-coating component, a linear motordrive guide rail (4), the suction mechanical arm (5) for the film-coating component, a glue supply device (6), an overturning sheet-unloading table (7) for the film-coating component, an overturningtransition frame (8) for the film-coating component, a sheet-unloading placement frame (9) for the film-coating component, an equipment support table (10), an equipment support (11), and an equipmentdustproof cover (12). The equipment is capable of forming a continuous and stable glue solution coating layer for the meniscus surface, has an anti-residual function, and is capable of completing continuous production for high-quality single-sided multilayer film-coated products or double-sided heterogeneous film-coated products.

Description

technical field [0001] The invention belongs to meniscus film coating equipment for continuous production of single-sided multi-layer or double-sided heterogeneous coating film products, and belongs to the field of continuous production of advection coating films. Background technique [0002] At present, many large-caliber optical switching devices, optical lenses, optical displays, etc. need to be coated with special coatings to change the surface properties, such as changing the light transmittance (anti-reflection coating or high-reflection coating), changing the abrasion resistance and prolonging the use of materials. Some require a single-sided multilayer film, and some require a double-sided heterogeneous film. The main method of coating the film layer in the industry is still the mainstream low-level physical method, such as the magnetron sputtering method, but the main disadvantage of the physical method is that it consumes a lot of energy and needs to be carried ou...

Problems solved by technology

The main method of coating the film layer in the industry is still the mainstream of the physical method, such as the magnetron sputtering method, but the main disadvantage of the physical method is that it consumes a lot of energy and needs to be carried out in a vacuum environment.

The wet chemical method just overcomes this major shortcoming. It can be applied under normal pressure with low energy consumption. At present, there is a pull-up method, but it cannot be used to coat a single film. Continuous coating is also limited by equipment on a certain basis; spin coating Although the method can be used to coat a single film, it cannot be coated with a large-diameter uniform single film, and it cannot achieve continuous film coating.

Therefore, only meniscus coating technology can meet these requirements. However, it is still limited in continuous production. At present, there is no meniscus coating equipment for continuous production of high-quality coating products.

[0003] Another main defect of the coating film of the existing meniscus coating technology is that the retention of the coating liquid at the tail end of the coating film element will cause defects at the tail end of the coating film product, reducing the quality of the coating film and the utilization rate of the coating film element
