Problems solved by technology

[0008] The object of the present invention is to provide a sealing frame glue coating device to solve the problem in the prior art that due to the offset of the substrate to be coated, the coating head of the frame glue coating mechanism can only proceed according to the original motion track. Movement and coating, resulting in the discrepancy between the sealant area coated by the coating head and the set coating area, which leads to the scrapping of the substrate to be coated

Embodiment 1

[0035] The basic idea of ​​the present invention is: Compared with ordinary glass substrate sealant coating equipment, the sealing sealant coating device of the present invention mainly includes a trajectory control mechanism that restricts the coating trajectory on the sealant coating mechanism. The trajectory control mechanism is used to synchronize the alignment with the substrate to be coated 60 carried on the large glass plate 50, wherein four corners of the large glass plate 50 are provided with induction marks 200, such as Figure 5 Shown. The end of the trajectory control mechanism is provided with a sensing part 100 and a control part (not marked in the figure). The sensing part 100 can sense the deflection angle and position of the sensing mark 200 in real time, and send the signal to the control part. The control unit then controls the trajectory control mechanism and the substrate to be coated 60 to be aligned and deflected synchronously. If the incoming direction o...

Abstract

The invention provides a sealing frame glue coating device. The sealing frame glue coating device comprises a glue frame coating mechanism used for spraying sealing frame glue in a set coating area of a to-be-coated base plate, and a track control mechanism used for controlling the frame glue coating mechanism to coat the set coating area with sealing frame glue, wherein the to-be-coated base plate is located below the frame glue coating mechanism. The frame glue coating mechanism synchronously moves along with movement of the track control mechanism, the track control mechanism can synchronously obtain the movement track of the to-be-coated base plate and conduct synchronous alignment with the to-be-coated base plate, and therefore the coating track of the frame glue coating mechanism can pass through the set coating area. According to the sealing frame glue coating device, the problem of abnormal frame glue coating caused by deflection of glass base plate incoming materials is solved, the frame glue coating track can be adjusted in time in the deflection direction of the glass incoming materials, the frame glue can be accurately sprayed to the set coating area, and the panel process capability is improved from the aspect of equipment.

Description

[0001] 【Technical Field】 [0002] The invention relates to the field of liquid crystal display, in particular to a sealing sealant coating device. [0003] 【Background technique】 [0004] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used. TFT-LCD has been very popular in daily life, such as TV, computer, mobile phone and other display screens. The technology in this field is constantly updated to better serve consumers. Continuous product upgrades have put higher requirements on TFT-LCD and put forward higher product quality requirements. [0005] The TFT-LCD (Thin Film Transistor Liquid Crystal Display) panel is composed of an array substrate and a color film substrate. The array substrate and the color film substrate are assembled by sealing frame glue and then pasted together. The edited panel is edited on the sealing frame glue coating machine. The required sealant graphics, using N 2 (Nitrogen) pressure, ...
