Abstract

The present application provides a coating device, the coating device is used to coat the sealant on the substrate, the coating device includes a first nozzle and a second nozzle, the first nozzle includes a first cavity and a first glue outlet The first glue outlet has a first glue outlet; the second nozzle is arranged on the inner peripheral side of the first nozzle and is slidably connected with the first cavity, and the second nozzle includes a second cavity and a second glue outlet , the second cavity is used to accommodate the frame glue, the second glue outlet head has a second glue outlet, the inner diameter of the second glue outlet is smaller than the inner diameter of the first glue outlet; when the coating device is in the first working state , the second glue outlet is set on the side of the first glue outlet close to the first cavity; when the coating device is in the second working state, the second glue outlet is set on the first glue outlet away from the first cavity side, or the second glue outlet is flush with the first glue outlet. This application satisfies the requirements of frame glue coating with different widths on the same large board, and improves the diversity of product design.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a coating device. Background technique [0002] The liquid crystal display panel is composed of an array substrate and a color filter substrate, which are assembled by sealing frame glue and pasted together. However, the current display panels are usually cut from a large board. Since there are display panels of different sizes on the same large board, the space reserved for the frame glue and the required frame glue when the panels of different sizes are aligned and assembled The widths are not the same, so higher requirements are put forward for coating equipment with different widths of frame glue on a large board. [0003] At present, when different widths of sealants need to be coated on the same large board, it is usually necessary to replace different coating jigs to meet the coating requirements of different widths of sealants. However, this setting not only i...
