Embodiment Construction
[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.
[0038] figure 1 and figure 2 Shown is a schematic structural view of a conventional cleaning device or a liquid knife of a developing device. The main material of the liquid knife is SUS (stainless steel), such as figure 1 and figure 2 As shown, the liquid knife 1 has a slit-shaped knife edge 2, and the width of the slit of the knife edge 2 of the entire liquid knife 1 must be roughly...

The present invention provides a liquid knife cleaning device and a liquid knife. The liquid knife cleaning device includes: a frame body for being arranged on the liquid knife and capable of reciprocating movement along the extending direction of the knife edge; A cleaning blade for extending into the knife edge of the liquid knife and capable of reciprocating movement in the knife edge driven by the frame body to clean the knife edge, the cleaning blade is arranged on the frame body and, a moving mechanism for reciprocating movement of the frame on the liquid knife along the extending direction of the knife edge, and the frame is connected with the moving mechanism. The liquid knife cleaning device provided by the present invention can replace the previous manual cleaning. Cleaning the knife edge of the liquid knife can reduce the probability of bifurcation of the liquid curtain, thereby reducing the probability of such developing MURA and improving the operation of the equipment. It also avoids other problems caused by discontinuous tape-out.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid knife cleaning device and a liquid knife. Background technique [0002] The main purpose of the color film factory in TFT-LCD (tin film transistor-liquid crystal display) is to coat photoresists of different colors on the glass substrate, and produce different colors through exposure, development, post-baking and other processes. graphics. The purpose of the development process of the color film factory is to remove the unexposed photoresist on the substrate, retain the exposed photoresist pattern, rinse the exposed glass substrate with diluted potassium hydroxide (KO) solution, and then wash it with pure water , to remove the KO residue. A liquid knife device is added to the connection area between the developing section and the cleaning section of the developing equipment to quickly remove the KO residual liquid and developing residue on the substrate surface, reduc...
