Embodiment Construction

[0021] As mentioned in the background art, the curvature of the curved surfaces on both sides of the cover plate in the prior art is quite different, and there may be technical problems such as air bubbles, black spots or fragments during the bonding process. The inventor found that the reason for this problem is that the current bonding equipment uses a silicone mold to bond the flexible screen to the cover as a whole, and there is a bonding pressure between the flexible screen and the cover. When the two sides of the cover When the curvature difference of the curved surface is too large, if the bonding pressure is too small, it will cause normal bonding on one side and bubbles on the other side; if the bonding pressure is too high, it will cause black spots or fragments on one side, and normal bonding on the other side. In order to solve the above problems, the inventor found that by measuring the curvature data of the curved surface of the cover plate, the supporting and fit...

Abstract

The invention provides a cover bonding device for a curved display panel, comprising: a measuring device for measuring the curvature data of the curved surface of the cover to be bonded; a controller connected with the measuring device for according to the The curvature data measured by the measuring device generates a control instruction; the supporting and bonding part is used to support the flexible screen to be bonded to the cover plate; the driving assembly connected to the supporting and bonding part and electrically connected to the controller , used to drive the supporting adhering portion to move along the curved surface of the cover according to the control instruction of the controller. The movement trajectory of the support fitting part is the same as the surface of the cover plate. During the fitting process, there will be no fragments or black spots due to excessive bonding pressure, and no air bubbles will occur due to too low bonding pressure. Effectively improve the lamination yield, improve the utilization rate of the cover plate, and reduce the production cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a cover laminating device for a curved display panel. Background technique [0002] During the manufacturing process of the curved display panel, it is necessary to bond the flexible screen to the CG (Cover Glass, cover plate). Due to external forces such as manufacturing process and handling, there are differences in the curvature of the curved surfaces on both sides of the cover. In the existing bonding process, if the curvature of the curved surfaces on both sides of the cover is greatly different, bubbles and black spots may appear during the bonding process. Defects such as spots or fragments. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a cover laminating device for a curved display panel, so as to solve the problems of easily causing bubbles, black spots or fragments in the existing laminating process. [0004] A ...
