Abstract
The invention relates to a method for laminating a shaped curved surface cover board to a flexible screen. The method comprises the following steps: adhering the back of the flexible screen to a laminating device, so as to obtain an initial assembly body; adhering an adhesive layer capable of curing and deforming to the front surface of the flexible screen; shifting the initial assembly body intothe shaped curved surface cover board, and then operating the laminating device to adhere the adhesive layer to the inner side of the shaped curved surface cover board, so as to obtain an initial laminating body; heating the adhesive layer in the initial laminating body, so as to enable the adhesive layer to flow, and then cooling. The laminating method has the advantages that the adhesive layer capable of curing and deforming is adopted, and the adhesive layer is heated to flow after initial laminating, so that adhesive sufficiently flows to positions which are not sufficiently adhered duringinitial laminating, particularly arc hook positions are more tightly adhered through the flowing of the adhesive, effective laminating is realized, and the quality of laminating of the whole flexiblescreen to the shaped curved surface cover board is further improved. The invention further discloses a laminating device.
Description
technical field [0001] The invention relates to the technical field of flexible screen bonding, in particular to a bonding method and a bonding device for a special-shaped curved surface cover plate and a flexible screen. Background technique [0002] Flexible screens are a new growth point for the industry in the future. The flexible features of flexible screens are constantly being developed and utilized. For example, attaching a flexible screen to a 3D fixed curved cover (both sides of the cover is a quarter of an arc) can realize Product front and side display. [0003] At present, the bonding method for realizing the flexible screen is to use a silicone pad to press and paste the flexible screen to the inner side of the glass cover. [0004] However, the bonding device in the prior art can only bond OLED panels with a small curvature, and cannot be used when the curved surface design of the cover plate tends to bend inward, that is, when the cover plate is a special-sh...
