Description

Technical Field

[0001] The utility model relates to the technical field of polarizer processing, in particular to a coating mechanism for polarizer processing. Background Art

[0002] The full name of the light sheet is polarizing sheet. It is an optical film composed of multiple layers of polymer materials and has the function of generating polarized light. Its basic structure includes: the middle PVA (polyvinyl alcohol) film and two layers of TAC (triacetyl cellulose) film. The polarizing sheet converts natural light without polarization into polarized light, and allows light that is perpendicular to the electric field to pass through, so that the liquid crystal display panel can display images normally. It is an indispensable part of the imaging of liquid crystal displays.

[0003] Polaroids are produced in the form of rolls during the production process. The production process from raw materials to semi-finished products is all in the form of roll winding and unwinding. In order to compound the corresponding functional films such as protective films, peeling films, compensation films, etc. onto the polaroid substrate, the traditional process is to use pressure-sensitive adhesive on the coating machine, by coating the pressure-sensitive adhesive on the functional film, and then compounding it onto the original polaroid substrate, and then drying and other processes to produce a finished roll of polaroids with certain functions.

[0004] Commonly used pressure-sensitive adhesives are generally toxic and harmful solvents such as ethyl acetate and acetone, which are very harmful to the human body. To solve this problem, the traditional method is to build a corresponding waste gas treatment system and emission system. On the one hand, the waste gas concentration can only be monitored within the standard range, and there is no way to completely isolate it. On the other hand, the cost is high.

[0005] Safety issues: In addition, ethyl acetate is flammable and volatile, and is a flammable and explosive chemical solvent. There are great safety risks during use, and some polarizer manufacturers have learned bloody lessons. The only way to solve this problem is through management measures.

[0006] At present, there is still a lack of equipment that can achieve film coating by using UV glue instead of commonly used pressure-sensitive adhesive. Utility Model Content
