step four, closing the sticky rotating diaphragm assembly on the mobile terminal film sticking device, enabling the positioning tear diaphragm of the rotating diaphragm assembly to be bonded with the non-sticky surface of the protective bonding film, and rolling the positioning tear diaphragm back and forth by utilizing a rolling piece to enable the positioning tear diaphragm to be firmly bonded with the protective bonding film; the step is used for ensuring that the protective film 4 can be accurately transferred to the positioning tear-off film; (where a rotating diaphragm assembly refers to either the first rotating diaphragm assembly 2 or the second rotating diaphragm assembly 5, and a positioning tear diaphragm refers to either the first positioning tear diaphragm 21 or the second positioning tear diaphragm 52);

lifting the positioning tear-off film to separate the protective film 4 and the positioning adhesive sheet 3 from the screen;

tearing off the release film adhered with the positioning adhesive sheet 3, cleaning the screen again, closing the positioning adhesive film 2 again to enable the protective adhesive film to be aligned and attached with the screen, and rolling the positioning adhesive film back and forth by utilizing a rolling piece to enable the protective adhesive film to be firmly adhered with the screen; in the step, the release film and the protective bonding film are separated into a corner part through the bonding sheet, then the release film is torn off by hands, and when the protective bonding film is firstly rolled by the rolling piece, the protective bonding film is bonded on the screen in an inclined gradual bonding mode to prevent bubbles;

and step seven, lifting the positioning tear film 2 to completely separate the positioning tear film from the protective adhesive film, thereby completing the film pasting of the mobile terminal 6.

The film pasting method provided by the embodiment of the application only needs to align the protective film 4 and the screen once, and does not need to carry out film pasting by holding the protective film 4, so that the film pasting method has the advantages of high film pasting efficiency, high film pasting precision and simplicity in operation, has wide market applicability, and solves the problem of difficulty in manually pasting soft films in the prior art.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
