Embodiment 1

[0030] Such as figure 1 As shown, this embodiment provides a coating device for a display panel, including: a panel cutting unit, which cuts adjacent panels to be cut. The cutting here can also be understood as pre-cutting, that is, the pre-cutting is completed. The display panel can enter the splitting process without the one-size-fits-all process, or perform the one-size-fits-all process again. Since the cutting is performed before the box, the influence of foreign matter caused by the adhesion of the frame sealing glue and cutting is reduced, thereby improving the yield of the cutting process.

[0031] It also includes: coating units located on both sides of the panel cutting unit, the coating unit is used to coat the adjacent panels to be cut, that is, the coating units on both sides simultaneously apply the edges of the panels to be cut on both sides Carry out the coating of the frame sealant; this can be coated on both sides at one time, avoiding the panel to be cut on each...

Embodiment 2

[0040] Such as figure 2 As shown, this embodiment provides a display panel coating device. The difference from the display panel coating device in Embodiment 1 is that the panel cutting unit includes a panel etchant nozzle 6 and a panel etchant supply mechanism 7, and a panel etchant nozzle 6 It is used to spray the panel corrosive on the panel to be cut; the panel corrosive supply mechanism 7 is used to supply the panel corrosive to the panel corrosive nozzle 6.

[0041] The panel corrosive agent corrodes the display panel (pre-cutting), which reduces the influence of foreign matter caused by the adhesion of the frame sealant and cutting, thereby improving the yield of the cutting process.

[0042] The coating device of the display panel is operated and controlled by a manipulator through the connection part 5, and at the same time, the frame sealant coating and display panel cutting processes are completed.

[0043] Preferably, the panel etchant nozzle 6 and the nozzle 3 of the c...

Abstract

The invention provides a coating device of a display panel, belongs to the technical field of display, and can solve the problems that in the existing manufacturing process of the display panel, product defects such as burr can be easily generated during the display panel cutting. The coating device of the display panel provided by the invention comprises a panel cutting unit and coating units, wherein the panel cutting unit is used for cutting an adjacent panel to be cut, and the coating units are positioned at the two sides of the panel cutting unit and are used for carrying out frame sealing glue coating on the adjacent panel to be cut. Through the inside pre-cutting (corrosion) before the sheet cracking of the display panel to be cut, the frame sealing glue adhesion influence and the foreign matter influence caused in the cutting can be reduced, so the qualification rate of the cutting process is improved, meanwhile, the double-side one-step coating of the display panel to be cut is realized, and the narrow side frame technology is favorably realized.

Description

Technical field [0001] The invention belongs to the field of display technology, and specifically relates to a coating device for a display panel. Background technique [0002] As consumers have higher and higher requirements for display panels, narrow bezel technology has been rapidly developed and applied. The display panel with a narrow frame design makes the visual effect feel wider; in addition, a limited area display panel can also be puzzled without spacing, thereby expanding the display application field. [0003] In the manufacturing process of traditional display panels (for example, TFT-LCD), the frame sealant is applied first, and then after the box matching process is completed, the cutting process is carried out; among them, the coating is single-sided coating, and two adjacent panels need Coating twice; after the box is cut, a one-size-fits-all method is generally used to cut the box. [0004] During the cutting process, due to the influence of the frame sealant on t...
