Abstract

The embodiment of the invention relates to a sealing frame glue coating device and method. The sealing frame glue coating device comprises a glue tube filled with sealing frame glue, a sealing frame glue nozzle connected with the glue tube, a laser sensor for detecting the distance between the sealing frame glue nozzle and a glass substrate, and a surfactant device, wherein the surfactant device is fixed on the sealing frame glue coating device; and the surfactant in the surfactant device is used for reducing the surface tension of the sealing frame glue residual on the sealing frame glue nozzle. The sealing frame glue coating device and the method of the embodiment of the invention have the advantages that the surface tension of the sealing frame glue residual on the sealing frame glue nozzle is reduced by the surfactant; and the defect that the starting point of the sealing frame glue on the glass substrate is obviously larger than the normal part is effectively reduced or avoided so that the incidence rate of the defects of glue leakage, uneven box thickness and the like can be effectively reduced, and the display effect of a liquid crystal display panel is enhanced.

Description

technical field [0001] The invention relates to the technical field of coating frame sealing glue for liquid crystal display panels, in particular to a frame sealing glue coating device and method. Background technique [0002] The liquid crystal display panel is formed by combining the array substrate and the color filter substrate, and injecting liquid crystal between the two substrates. In order to seal the array substrate and the color filter substrate to cut off the contact between the liquid crystal molecules and the outside world, maintain the thickness of the cell between the array substrate and the color filter substrate, and ensure the display effect of the liquid crystal display panel, it is necessary to use a sealant. The location is located around the LCD panel. The main component of the frame sealant is resin, and there are heat curing type and light (UV) curing type. [0003] figure 1 It is a schematic diagram of a frame sealing glue pattern coated on a gla...
