Problems solved by technology

[0006] At this time, the front end of the blade should be in contact with the surface of the nozzle lip in parallel, but in the prior art there is a need to make the front end of the blade contact with the surface of the nozzle lip in parallel. A problem that puts a lot of time and effort into
[0007] Moreover, when the nozzle lip cleaning device moves at a high speed while scraping off the liquid medicine, the liquid medicine separated from the nozzle lip by a certain blade affects other blades while the blade is moving, so there is a The problem of poor cleaning

Abstract

The present invention provides a nozzle lip cleaner and a slit coater using the same, the nozzle lip cleaner comprising: a cleaner main body; a blade support unit that has a first blade support member coupled to the cleaner main body; a blade unit that has a first blade, the rear end of which is coupled to the first blade support member, and the front end of which is brought into contact with the surface of the nozzle lip in order to scrape liquid chemical off the surface of the nozzle lip after the liquid chemical is discharged; an angle adjustment unit that has a first angle adjustment member provided in the cleaner main body to adjust the relative position between the front end of the first blade and the surface of the nozzle lip while moving the first blade support member; and a support pin unit that has a first support pin member disposed between the first blade support member and the first blade to serve as the center of rotation of the first blade in a width direction such that the front end of the first blade is brought into contact with the surface of the nozzle lip in parallel when the first blade support member moves.

Description

technical field [0001] The present invention relates to a nozzle lip cleaning device and a slit coating device utilizing the nozzle lip cleaning device, more specifically, a nozzle lip cleaning device and a slit coating device utilizing the nozzle lip cleaning device, The blade used for cleaning the mouth of the nozzle is accurately and quickly arranged on the surface of the mouth of the nozzle, and at the same time, the cleaning force of the mouth of the nozzle can be improved. Background technique [0002] The substrate manufacturing process for flat panel display elements includes a coating process of applying various chemical solutions to the surface of the substrate, and the coating equipment used in the coating process mainly uses a slit coating device with a slit nozzle. [0003] The slit-type application device moves instantaneously from one side of the substrate to the other side while spraying the chemical solution through the slit-type nozzle, and then applies the...
