Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] Such as figure 1 As shown, the present invention provides a peripheral auxiliary frame sealant coating device, which includes: a rubber tube 1 with a built-in frame sealant, a frame sealant needle 2 connected to the rubber tube, and a needle for detecting the frame sealant 2 and The laser sensor for the distance between the substrates 5 also includes a glue-coated guiding structure 3 on one side of the substrate 5 .

[0032] In one embodiment, the gluing guiding structure 3 includes a gluing starting section 31 for starting gluing and a gluing ending section 32 for gluing, and a gap 33 is provided between the starting section 31 and the terminating section 32 .

[0033] Since a gap 33 is provided between the starting section 31 and the ending section 32, coating is started from the starting section 31 until reaching the ending section 32, and the coating is finished...

Abstract

The invention relates to a peripheral auxiliary frame sealing adhesive coating device and method and relates to the technical field of liquid crystal display. The device and method are used for solving the technical problem of poor display caused by the uneven cell thickness, of a liquid crystal panel in the prior art. The peripheral auxiliary frame sealing adhesive coating device comprises an adhesive coating guide structure located at one side of a substrate, by the arrangement of the adhesive coating guide structure, when an adhesive is coated, a frame sealing adhesive needle coats prescribed coating positions, overlap between an initial position and an end position is avoided, the adhesive quantity of interfaces of the initial position and the end position is the same as those of the other areas, and the situation of the poor display caused by the uneven cell thickness is avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a peripheral auxiliary frame sealing glue coating device and method. Background technique [0002] The liquid crystal display device has many advantages such as a thin body, power saving, and no radiation, and has been widely used. In the process of manufacturing a liquid crystal display device, the color filter substrate and the array substrate need to be vacuum-boxed. The main sealant and auxiliary sealant are coated on the color film substrate, and the auxiliary sealant is used to provide better support and protect the main sealant during the box alignment process. [0003] When the existing sealant is coated, the initial coating and the interface where the coating is terminated will overlap, and the amount of glue in the overlapping area will be too much, which will cause the problem of uneven box thickness, thus This leads to the problem of poor display of t...
