Embodiment Construction

[0028] A detailed description of preferred embodiments of the present invention is provided below with reference to the accompanying drawings. The present invention is a method of applying a coating to a substrate, wherein, as figure 1 As shown, the nozzle holder 5 supporting the nozzle 4 by the nozzle positioners 3a-3c moves in the front-rear direction relative to the table 2 so as to apply the liquid medium L to the substrate 1S on the table 2 (for testing samples of protective coatings) and 1P (products). In this method, distance sensors 6 a - 6 c installed before processing are used to measure the distance between the surface LS of the coating on the substrate 1S and the nozzle 4 . To start the process, the test substrate 1S is placed on the table 2, and the test liner is tentatively coated by the nozzle 4 while the nozzle holder 5 is moved on the table 2 in a forward direction relative to the table 2. Bottom 1S. Then, the distance sensors 6a-6c perform a measuring oper...

Abstract

The invention relates to a method for coating a coat onto a substrate for effectively controlling surface of the coat spraying liquid medium on the substrate through a nozzle, effectively controlling formation of thickens of the coat forming through the liquid medium, and maintaining quality control of the coat with high production efficiency, comprising the following operation steps of: firstly installing a distance sensor 6a-6c, for measuring the distance between a medium layer surface LS forming on substrate 1S and 1P and a nozzle 4; putting a measuring substrate 1S on a work bench 2, and undergoing coat measurement for the measuring substrate 1S through the liquid medium sprayed by the nozzle when a nozzle clamp holder 5 moves forwards related to the work bench, performing measurementoperation by the distance sensor when the nozzle clamp holder moves backward related to the work bench, starting a nozzle positioner 3a-3c according to a result of measurement operation performed by the distance sensor, as the device setting nozzle position for forming suitable coat, so as to coat the liquid medium L onto the substrate 1P.

Description

technical field [0001] The present invention relates to a method of applying a coating to a substrate, wherein the coating surface of a liquid medium sprayed on the substrate through a nozzle can be effectively controlled, the thickness of the coating formed by the liquid medium can be effectively controlled Form, and maintain coating quality control with high productivity. Background technique [0002] The technology involved in applying high-quality coatings to plasma display panels and the like requires a method that can be interpreted as managing the application of panel coatings. This technique is described in References 1 to 3 noted in this application. Reference 1 is a Japanese unexamined patent publication titled "Coating Apparatus, Coating Method, Apparatus for Preparing Color Filters and Preparation thereof", which describes a high-speed uniform coating of glass substrates A method that is applicable to large-sized glass substrates and can maintain a uniform gap ...
