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 coating frame sealant. Nozzle; the tube wall of the rubber storage tube is made of flexible material, and the tube wall can undergo recoverable inward deformation perpendicular to the axis of the rubber storage tube. The invention can effectively avoid problems such as hanging glue.

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 conversion), Dual Domain (double layer), HRP (High Resolution Process, high resolution rate), etc. Among them, ODF is a new type of high-tech that integrates a series of technologies such as Hot Press (hot pressing) and LC Fill (Liquid Crystalfill), End Seal (sealing glue), Cell Cleaner (cleaning), and Cell Annealing (annealing). 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...
