Substrate coating device

Abstract

The invention discloses a substrate coating device and belongs to the field of electronic equipment manufacturing. The substrate coating device is sequentially provided with a coating cover and a hollow containing table along gravitational potential energy from high to low. A clamping plate is arranged on the surface of the containing table, and a covering plate, a heat supply part and a driving pair are arranged in the containing table, and the covering plate is flatly laid on the surface of the containing table and is lower than a sliding rail. At least two sets of chutes are formed in the surface of the covering plate, and the chutes are staggered. A hook-face substrate generally comprises a concave face and a convex face. When the convex face of the hook-face substrate is in contact with ejection blocks, the different ejection blocks descend according to different curvature degrees of the surface of the hook-face substrate, a nozzle is close to the concave face of the hook-face substrate, and the distancesbetweenthe nozzle and all pointsarethe same. Therefore, the diffusance of coating liquid sprayed out by the nozzle on the hook-face substrate is the same, even coating of thehook-face substrate is achieved, and the coating thickness is equal. The substrate coating device achieves the aim that the hook-face substrate is evenly coated.

Description

technical field [0001] The invention discloses a substrate coating device belonging to the field of electronic equipment manufacturing. Background technique [0002] With the continuous advancement of technology, the function of the liquid crystal display substrate is not limited to fixing liquid crystal molecules, but also expands the touch function on the glass substrate. Usually, the touch points are mainly in the RGB pixel grid. The realization of these liquid crystal display multifunctional technologies is inseparable from the substrate coating technology. The substrate can not only change its own conductivity through coating, but also change its own refractive index through coating. [0003] It can be seen that in the manufacturing process of liquid crystal display, the importance of the substrate coating step is very important. The coating technology of traditional flat substrates has been perfected day by day. With the development and progress of the market, the mar...

AI Technical Summary

Problems solved by technology

Although curved liquid crystal displays have broad prospects, their special shape brings great difficulties to the coating process. The metal film ejected from the nozzle often covers unevenly on the curved substrate, which affects the quality of the output display. performance and sensitivity

Due to the shape of the curved substrate, the coating solution ejected from the nozzles on the same horizontal plane reaches the curved surface at different times, so the kinetic energy obtained by the coating solution is different when it flies in the air, resulting in different spreading ranges of the coating solution after hitting the curved surface, which affects Thickness of coating solution
