Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display panels, in particular to a high-efficiency alignment film printing machine fixture. Background Art

[0002] In the process of liquid crystal display panel manufacturing, the process of alignment film is generally to use an alignment film printer (picoater, pic) to use the printing principle to evenly apply a layer of alignment film liquid, generally a polyimide solution (pi liquid for short) according to the designed area on the glass substrate, and then heat it with a heating plate to accelerate the volatilization of the solvent in the pi liquid, thereby initially forming a thin film for the alignment of liquid crystal molecules.

[0003] At present, the process of the alignment film is specifically as follows: PIC uses the alignment plate (APR plate for short) to transfer the Pi liquid, and uses pressure to drip the Pi liquid onto the transfer wheel (aniloxroll, i.e., wheel A) through the nozzle, and the scraper flattens the Pi liquid on the wheel A. The circular protrusions on the APR plate squeeze out the Pi liquid in the groove of the wheel A and take it away, and then the Pi liquid on the APR plate is evenly transferred to the glass substrate, thereby achieving the coating of Pi, and finally forming the alignment film through heat treatment. However, in the existing process, when the wheel A transfers the Pi liquid to the APR plate, in view of the above-mentioned transfer process, a large amount of Pi liquid will fall into the liquid tray located below the wheel A, and then be discharged into the waste liquid barrel and directly discarded. Preliminary calculations show that about 10 kg of Pi waste liquid will be generated in the waste liquid barrel every day, resulting in a loss of more than 2 million per month, which results in a huge waste of material costs.

[0004] Based on this, the utility model designs a high-efficiency alignment film printing machine fixture to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency alignment film printing machine fixture to solve the above technical problems.
