In the embodiment of the present application, as shown in fig. 2 and 9, the first hollow cavity 14 continues to be pumped, so that the pressure of the first hollow cavity 14 is reduced, the peripheral side of the supporting wall 11 is deformed, and thus the flexible screen and the OCA tape 51 adsorbed on the supporting wall 11 are deformed. The shape of the surface of the curved cover plate 60 facing the side of the flexible member 50 to be attached is the same as or similar to the shape of the flexible member 50 to be attached which is released and deformed.
S300: the press-fit element 20 located inside the contoured pad 10 is moved along the surface of the second side of the support wall 11 and the press-fit element 20 is caused to apply pressure to the surface of the second side of the support wall 11 to cause the flexible element 50 to be attached to the curved cover sheet 60.
Specifically, in the embodiment of the present application, the pressing member 20 located inside the profiling pad moves along the surface of the second side of the supporting wall 11 corresponding to the plane of the curved cover plate 60, and the pressing member 20 applies pressure to the surface of the second side of the supporting wall 11, so that the flexible member 50 to be attached is attached to the plane of the curved cover plate 60.
The pressing member 20 moves to the surface of the second side of the supporting wall 11 corresponding to the curved surface of the curved surface cover plate 60, and the pressing member 20 deforms, and the shape of the pressing member 20 matches the curved surface of the curved surface cover plate 60, so that the pressing member 20 applies pressure to the surface of the second side of the supporting wall 11, and the flexible member 50 to be attached is attached to the curved surface of the curved surface cover plate 60.
As shown in fig. 10, the presser 20 applies pressure to the support wall 11 by moving the presser 20 inside the contoured pad 10 along the support wall 11, the direction of the arrow in fig. 10 being the direction of movement of the presser 20. At the plane position of the curved cover plate 60, the pressing part 20 is driven to move through the driving mechanism 30, the pressing part 20 presses the supporting wall 11 and the flexible screen body and the OCA adhesive tape 51 are attached to the curved cover plate 60, and the flexible screen body is bonded to the curved cover plate 60 through the OCA adhesive tape 51; when the pressing member 20 moves to the curved surface of the curved surface cover plate 60, an inflator (not shown) inflates air into the second hollow cavity 21 of the pressing member 20, so that the pressing member 20 deforms, and the flexible screen body is tightly attached to the curved surface of the curved surface cover plate 60.
The above embodiments are merely examples and are not intended to limit the scope of the present disclosure, and all modifications, equivalents, and flow charts using the contents of the specification and drawings of the present disclosure or those directly or indirectly applied to other related technical fields are intended to be included in the scope of the present disclosure.
