Problems solved by technology

It will happen when the glue is squeezed out, the middle has been emptied, but the residual glue on the surrounding pipe wall cannot be sprayed down
In the coating process of the existing sealant, the piezoelectric device is used alone for uniform pressure and uninterrupted coating of the sealant, because the long-term use of the piezoelectric device will cause the internal charge of the internal piezoelectric ceramics to accumulate, and the coated sealant Glue stability is poor
Using CDA alone cannot achieve a uniform force on the sealant
Due to the high viscosity of the sealing frame, it is not suitable for separate inkjet glue application

Abstract

The invention discloses a coating device, a coating system and a coating method for frame sealing glue. The coating device comprises a glue storage pipe, one end of the glue storage pipe is connected with a gas blowing-out device, and the other end of the glue storage pipe is connected with a nozzle. The pipe wall of the glue storage pipe is made of flexible materials, and the pipe wall can recoverably deform inwards in a mode perpendicular to the axis of the glue storage pipe. The coating device can effectively solve the problem of glue hanging.

Description

technical field [0001] The invention relates to a coating device, a coating system and a coating method, in particular to a frame sealing glue coating device, a coating system and a coating method, and belongs to the technical field of display device manufacturing. Background technique [0002] In recent years, representative cutting-edge technologies adopted in the LCD industry include ODF (One Drop Fill, liquid crystal drop), IPS (In-Plane Switching, plane switching), Dual Domain (double layer), HRP (High Resolution Process, high resolution), etc. Among them, ODF is a new type that integrates a series of technologies such as Hot Press (hot pressing) and LC Fill (Liquid Crystal fill), End Seal (sealing glue), Cell Cleaner (cleaning), and Cell Annealing (annealing) in the past. High efficiency technology. The ODF process includes dripping liquid crystals on one substrate (TFT or CF), and uniformly coating the sealant on the other corresponding substrate. After coating and ...
