Description

technical field

[0001] The invention relates to a coating process, in particular to a coating machine and a method for detecting and removing dust particles thereof. Background technique

[0002] Since dust particles can adversely affect the coating effect of the substrate, it is necessary to detect dust particles. The foreign matter detection of the existing coating machine is realized through the laser transmitter and the laser receiver respectively arranged on both sides of the front bottom of the Gantry, such as figure 1 shown. Below the structure of existing coating machine is briefly described, as figure 1 , 2 As shown, the coating machine includes: a machine platform 1 for carrying a substrate, a gantry 2 for coating the substrate, and directly below the gantry 2 is a nozzle 3, that is, the outlet of the coating liquid, and the outlet of the nozzle 3 A slit is formed, the length of which is basically the same as the width of the substrate. The front side of the ga...
