Abstract

The invention provides a coating device which is used for coating frame glue onto a base plate. The coating device comprises a first nozzle and a second nozzle. The first nozzle comprises a first cavity and a first glue outlet end, and the first glue outlet end is provided with a first glue outlet. The second nozzle is arranged on the inner circumferential side of the first nozzle and further connected with the first cavity in a sliding mode. The second nozzle comprises a second cavity and a second glue outlet end. The second cavity is used for containing the frame glue, and the second glue outlet end is provided with a second glue outlet. The inner diameter of the second glue outlet is smaller than that of the first glue outlet. When the coating device is in a first operating state, the second glue outlet is formed in the side, close to the first cavity, of the first glue outlet. When the coating device is in a second operating state, the second glue outlet is formed in the side, faraway from the first cavity, of the first glue outlet, or the second glue outlet is flush with the first glue outlet. By adoption of the coating device, the coating requirement of the frame glue with different widths on the same big plate is met and product design diversity is improved.

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...
