[0038] In the display screen film pasting jig of the embodiment, the display screen placing platform 11 is uniformly arranged with eight first grooves 12, and the first suction hole 13 is arranged in the middle of the inner bottom wall of each first groove 12; and the protective film placing platform 21 is uniformly arranged with eight second grooves 22, and the second suction hole 23 is arranged in the middle of the inner bottom wall of each second groove 22. In this way, the display screen and the protective film are more uniformly stressed, and the phenomenon of the protective film generating pore marks caused by the single second suction hole 23 is avoided.

[0039] In the display screen film pasting jig of the embodiment, the first cavity is arranged in the display screen fixing plate 1, the first suction hole 13 and the first air pipe joint 14 are in communication with the first cavity; and the second cavity is arranged in the protective film fixing plate 2, the second suction hole 23 and the second air pipe joint 24 are in communication with the second cavity.

[0040] In this way, the air suction device connected with the first air pipe joint 14 sucks the air in the first groove 12 through the first cavity and the first suction hole 13, so that a vacuum state is formed in the inside of the first groove 12, thereby the display screen is adsorbed on the display screen placing platform 11. The second suction hole 23 and the second groove 22 are cooperated to adsorb and fix the protective film on the protective film placing platform 21. Specifically, the air suction device connected with the second air pipe joint 24 is used to suck the air in the second groove 22 through the second cavity and the second suction hole 23, so that a vacuum state is formed in the inside of the second groove 22, thereby the protective film is adsorbed on the protective film placing platform 21.

[0041] The working principle of the display screen film pasting jig of the embodiment is as follows:

[0042] The protection film fixing plate 2 and the display screen fixing plate 1 are both hollow cavity structures, and the cavities of the two are communicated with the corresponding air pipe joint and the eight adsorption holes respectively. During the process of attaching the protection film, the protection film fixing plate 2 is first opened upward, and the protection film and the display screen are placed in the protection film fixing plate 2 and the display screen fixing plate 1 respectively, then the corresponding air pipe joints are connected with the air suction device to perform air suction respectively, and the protection film and the display screen are adsorbed through the adsorption holes of the protection film fixing plate 2 and the display screen fixing plate 1 respectively. Since the adsorption holes are all arranged in the grooves, a vacuum state is formed in the grooves during the adsorption process, and the adsorption holes and the grooves are arranged in order and uniformly, so that the protection film and the display screen are subjected to uniform force and are not easy to form pore marks on the surfaces thereof.

[0043] When the protection film is adsorbed and fixed on the protection film placing platform 21 and the display screen is adsorbed and fixed on the display screen placing platform 11, the protection film fixing plate 2 is rotated downward by the hinge structure 3, and the display screen fixing plate 1 is not rotated horizontally and is avoided from falling off from the display screen placing platform 11. 1 During the pressing process, the positioning pin 5 on the display screen fixing plate 1 is inserted into the positioning hole 51 on the protection film fixing plate 2, so that the protection film fixing plate 2 and the display screen fixing plate 1 are accurately attached. When the protection film fixing plate 2 and the display screen fixing plate 1 are accurately attached according to the cooperation of the positioning pin 5 and the positioning hole 51, the first magnetic connecting piece 15 and the second magnetic connecting piece 25 are adsorbed to each other, so that the protection film and the display screen are more uniformly and closely attached as a whole. When the protection film attaching work is completed, the air suction device is controlled to stop air suction, the protection film fixing plate 2 is opened upward by the hand groove 6 on the protection film fixing plate 2, the display screen with the attached protection film is taken off, and the next cycle of attaching the protection film and the display screen is performed. The display screen attaching jig of the embodiment can more quickly, simply and accurately ensure the attachment of the protection film of the display screen.

[0044] The display screen attaching jig of the embodiment has the following beneficial effects:

[0045] 1. The hinge structure 3 is adopted to realize the up-down rotation of the protection film fixing plate 2 and the display screen fixing plate 1, and the display screen attaching jig is integrated, so that the working intensity of the operator is greatly simplified and the productivity is improved.

[0046] 2. The grooves are additionally arranged on the adsorption holes to increase the adsorption area, reduce the excessive pressure generated during the adsorption process, make the adsorption more uniform, avoid the formation of pore marks on the protection film, ensure the attachment quality of the protection film, and improve the qualified rate of the product.

[0047] 3、In the display screen fixed plate 1 using soft positioning block 4 for adjusting position and protection display screen, so that the display screen in the process of placing from the knock damage, and in the process of film to ensure that the display screen does not occur displacement change, and then improve the protection film to the quality.

[0048] 4、In the protection film fixed plate 2 and display screen fixed plate 1 using magnetic connection, avoid the traditional process of protection film and display screen exists in the process of not close, not uniform, etc. Make protection film and display screen more uniform, close, and then improve the protection film to the quality, to ensure the qualified rate of products.

[0049] 5、In the display screen fixed plate 1 and protection film fixed plate 2 using the positioning pin 5 and positioning hole 51, so that the protection film to ensure that the protection film to the process of more accurate.
