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.
