Problems solved by technology

[0007] It can be seen from the above technical solutions that the present invention adopts the technical means of setting two storage chambers in the sealing glue coating device to store the conductive sealing glue and the insulating sealing glue respectively, and setting a control device to control the flow rate, which overcomes the problem of conductive sealing glue. Adhesive and insulating sealant need to be coated in two processes separately, or only conductive sealant is applied, resulting in technical problems of low production efficiency, electrostatic breakdown, low product yield and high cost

Embodiment Construction

[0014] Embodiment 1 of the sealing glue coating device

[0015] Such as figure 2 Shown is a schematic structural diagram of a specific embodiment 1 of the frame sealing glue coating device of the present invention. The device specifically includes a first storage chamber 10, a second storage chamber 20, a nozzle 2 and a first control valve 12. The first storage chamber 10 is used for For storing the conductive frame sealant 11, the conductive frame sealant 11 is a frame sealant with a conductive function, such as a frame sealant mixed with conductive microspheres; the second storage chamber 20 is used to store the insulating frame sealant 21, the insulating frame sealant Glue 21 is the sealant that has no conductive function or is not mixed with conductive microspheres; the spout 2 is respectively connected to the first storage cavity 10 and the second storage cavity 20, and is used to guide the conductive sealant 11 and / or insulate The sealant 21 flows out so as to be coate...

Abstract

The present invention relates to a frame-enveloping adhesive coating device which comprises the following components: a first storing chamber which is used for storing conductive frame-enveloping adhesive; a second storing chamber which is used for storing insulated frame-enveloping adhesive; a nozzle which is respectively connected with the first storing chamber and the second storing chamber and is used for coating frame-enveloping adhesive; and a first controller which is connected with the first storing chamber and is used for controlling the outflow capacity of conductive frame-enveloping adhesive. The frame-enveloping adhesive coating device according to the invention realizes the separated coating of conductive frame-enveloping adhesive and insulated frame-enveloping adhesive, simplifies the technical process and increases the production efficiency. Simultaneously the conductive frame-enveloping adhesive is coated properly. The generation of electrostatic breakage phenomenon is prevented. The qualified rate of product is increased and the product cost is reduced.

Description

technical field [0001] The present invention relates to a frame sealant coating device, in particular to a frame sealant coating for bonding two substrates in a Thin Film Transistor-Liquid Crystal Display (hereinafter referred to as TFT-LCD) device. Background technique [0002] The principle of TFT-LCD technology is to drive the liquid crystal molecules between the two substrates through the pixel electrodes to make them deflect, and then work together with the upper and lower polarizers to control the strength of the transmitted light, so as to realize the display function. The two substrates are respectively an Array substrate with pixel electrodes and a color filter substrate with red, blue and green pixels. [0003] In the process of making TFT-LCD, it is necessary to combine the array substrate and the color filter substrate and pour liquid crystal into it. This process is called "cell matching process". In the box-to-box process, first apply the sealant around the p...
