9. A method for using the liquid crystal display film pasting device as claimed in any one of claims 1 to 8, characterized in that the method comprises the following steps:
s1: one side of the protective film is placed on the arc-shaped elastic rubber plate (8) and the position of the protective film is adjusted, the vacuum suction sheet (29) sucks the protective film on the arc-shaped elastic rubber plate (8) by pressing the hollow column (27), and then the separable film on the protective film is taken down;
s2: firstly, a rotating rod (16) is rotated to drive a rotating gear (17) and an adjusting gear (15) to rotate, the adjusting gear (15) drives a screw rod (12) connected with the adjusting gear to rotate, the screw rod (12) drives another corresponding screw rod (12) to rotate through a cross inserting column (11), so that the rotating screw rod (12) rotates to drive a long connecting rod (13) and a positioning clamping plate (14) to move a certain distance in a direction away from each other, then the position, adjusted by the positioning clamping plate (14), of the positioning clamping plate is proper to a display screen, the rotating rod (16) is rotated reversely, four corners of the display screen are clamped by the four positioning clamping plates (14), positioning is carried out, then the middle position of a protective film is in close contact with the display screen, and then the four positioning clamping plates (14) are fastened;
s3: then, the bidirectional screw rod (7) is rotated, the bidirectional screw rod (7) drives the two movable sliding plates (19) to move towards directions far away from each other, the arc-shaped elastic rubber plate (8) is continuously extruded through the pressing plate (31), so that a protective film on the arc-shaped elastic rubber plate (8) is adhered to a display screen, meanwhile, when the movable sliding plate (19) drives the telescopic rod (35) to move, the rolling balls (38) are continuously contacted with the plurality of rotating balls (33), and under the action of the torsion spring, the rolling balls (38) are continuously moved up and down, so that the telescopic rod (35) drives the pressing plate (31) to continuously move up and down, and the quality of the adhered film is improved;
s4: after the device is attached, the sealing cover (28) on the hollow column (27) is loosened, so that the vacuum suction sheet (29) is separated from the protective film, and then the four positioning clamping plates (14) are loosened, and the device is taken down.
