The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

As shown in Figures 1 to 3, a backplane film sticking device is used to automatically stick a film on the backplane of a display screen. Film frame 20, rolling pressing mechanism 60 and cutting mechanism, wherein, placing table 11 is used for placing the backboard of protective film to be pasted; Roll film frame 20 is arranged on one end of placing table 11, and is used for carrying protective film coiled material; The rolling pressing mechanism 60 is arranged above the placing table 11, and is used for rolling and pressing the protective film to the top surface of the backboard placed on the placing table 11; space, and for cutting the protective film. During work, the backboard is placed on the placement table 11, the protective film on the roll film frame 20 is pulled to the top of the backboard, and the protective film and the backboard are rolled and pressed by the rolling pressing mechanism 60, so that the protective film and the backboard The top surface of the backplane is completely attached, and then the protective film is cut by a cutting mechanism, so that the protective film attached to the backplane is separated from the protective film on the film roll frame 20, thereby completing the film sticking action of the backplane, effectively improving the backplane. The phenomenon of poor adhesion of the protective film of the board, and the work efficiency is high.

Specifically, as an embodiment of the present utility model, the rolling pressing mechanism 60 includes: a driving rod 61 arranged horizontally, a roller 62, a lifting driving device 66 and an X-axis driving device 67, wherein the roller 62 is sleeved on the driving rod 61, and can rotate relative to the drive rod 61; the lifting drive device 66 is connected with the drive rod 61, and is used to drive the drive rod 61 and the roller 62 to move up and down together; the X-axis drive device 67 is connected to the lift drive device 66, and used to drive The lifting driving device 66 , the driving rod 61 and the roller 62 move together along the X-axis direction. During work, drive the driving rod 61 to move downward through the lifting drive device 66, and drive the roller 62 to move downward until the roller 62 presses the protective film on the top surface of the backboard; the X-axis driving device 67 drives the lifting drive device 66 and The driving rod 61 moves along the X-axis direction, and drives the roller 62 to roll along the X-axis direction, thereby pressing the protective film and the top surface of the backboard firmly, avoiding wrinkles and air bubbles, and greatly improving the working efficiency. The rolling and pressing mechanism 60 is suitable for the case where the film sticking surface of the backboard is flat.

However, the backplanes used in the existing curved display screens are curved backplanes, and it is also necessary to stick a film on the curved surface of the curved backplane. In order to further solve the film sticking problem of the curved backplane, a height adjustment mechanism capable of automatically adjusting the height of the driving rod 61 is added to the above-mentioned rolling pressing mechanism 60 . Specifically, the height adjustment mechanism includes: a connecting plate 63, two "T" shaped guide rods 64 and a spring 65, wherein the connecting plate 63 is arranged above the drive rod 61 and connected with the lifting drive device 66; The bottom ends of the rods 64 move vertically through the connecting plate 63 and are respectively connected to the two ends of the driving rod 61 ; the spring 65 is sleeved on the guide rod 64 between the connecting plate 63 and the driving rod 61 . In this way, by using the elastic effect of the spring 65, the height of the driving rod 61 can be adjusted in time according to the curved surface of the backboard, so as to ensure that the roller 62 rolls and compacts the protective film. In addition, this structure can also buffer the impact force of the lifting drive device 66 and prevent the backboard from being crushed.
