the method comprises the following steps: the display is placed on a plane, and a glue layer is coated in an embedded groove in the middle of the surface of the display, so that the coated glue layer in the embedded groove is in a curing state and does not flow any more;
step two: coating an adhesive layer on the bottom end surface of the curved screen, so that the adhesive layer coated on the bottom end surface of the curved screen does not flow any more when being in a curing state;
step three: placing the curved screen in a curved surface fitting jig, and performing optical full-fitting on the curved screen and the surface of the display;
step four: placing the attached curved display screen into a defoaming machine so as to eliminate part of bubbles which are not completely eliminated in the attaching process;
step five: sealing the frame of the deaerated curved surface display screen with glue;
step six: and taking out the curved surface display screen, and removing the residual glue overflowing along the edge so as to finish the attachment.
Further, the curved surface laminating tool is located between curved surface screen and the display, seamless laminating between curved surface laminating tool and curved surface screen and the display.
Compared with the prior art, the invention has the following beneficial effects:
(1): compared with the traditional scheme that glue can only be applied to a plane glass, a plastic cover plate or a touch screen and is attached, the method can convert the attachment of a product, which cannot be coated with a glue layer, of the curved glass or the plastic cover plate into the planar glue layer coating, then enables two products with the same curvature to be attached, breaks the bottleneck that the curved surface attachment is difficult to produce, is simple and convenient to operate, and facilitates the realization of batch production.
