[0024] Please refer to Figure 1-4 As shown, the utility model provides a light guide plate film laminating tool, including a film laminating table 1 and a smoothing structure, the top side of the film laminating table 1 is provided with a placement rack 2 for placing the light guide plate, the top side of the film laminating table 1 is provided with a fixing structure for fixing the light guide plate, after the fixing structure fixes the light guide plate placed on the top side of the placement rack 2, it can prevent the light guide plate from moving during the film laminating process and affecting the film laminating effect.

[0025] The smoothing structure comprises a connecting frame 5 , a smoothing cylinder 6 is rotatably mounted on the bottom side of the connecting frame 5 , and a driving assembly for driving the connecting frame 5 to slide back and forth transversely is arranged on the top side of the coating platform 1 .

[0026] By driving the smoothing cylinder 6 to slide back and forth through the driving component, the outer film placed on the top side of the light guide plate can be adhered to the top side of the light guide plate. At the same time, since the heights of different positions of the outer wall of the smoothing cylinder 6 are the same, the outer film can be more evenly adhered to the outside of the light guide plate during the rolling of the smoothing cylinder 6.

[0027] The driving assembly includes a guide plate 7. The coating table 1 is an L-shaped structure. The guide plate 7 is fixed on the top side of the coating table 1. A movable plate 8 is slidably installed on the outer wall of the guide plate 7. A control plate 9 is fixed on the top side of the movable plate 8. A lifting device for driving the connecting frame 5 to rise and fall is arranged between the bottom of the control plate 9 and the middle of the top side of the connecting frame 5.

[0028] By opening the lifting device, the height of the smoothing cylinder 6 can be adjusted to make the bottom outer wall of the smoothing cylinder 6 fit with the outer film of the outer wall of the light guide plate. By rolling the smoothing cylinder 6 on the outer wall of the light guide plate, the outer film can be attached to the outer wall of the light guide plate and the film sticking process of the light guide plate can be completed.

[0029] The driving assembly also includes a transmission rod 10, which is rotatably installed on the side wall of the coating table 1 near the top. The outer wall of the transmission rod 10 is threadedly connected to the inner wall of the control panel 9.

[0030] When the light guide plate is being filmed, the light guide plate is placed on the top side of the placement rack 2, and the outside is wrapped around the top side of the light guide plate. Then, the lifting device is started to drive the connecting rack 5 to fall, and the bottom of the smoothing tube 6 is fitted with the top side of the light guide plate.

[0031] Turn on the power device to drive the transmission rod 10 to rotate. The principle of threaded transmission can be used to drive the control plate 9 to slide along the outer wall of the transmission rod 10, and the movable plate 8 can slide on the outer wall of the guide plate 7 at the same time. The sliding process of the control plate 9 can drive the connecting frame 5 at the bottom to slide along the outer wall of the transmission rod 10 at the same time, and drive the smoothing cylinder 6 at the bottom of the connecting frame 5 to roll on the top side of the light guide plate to stick the outer film to the top side of the light guide plate, thereby completing the film sticking process of the light guide plate.

[0032] The coordinated use of a power device, a driving assembly, a lifting device and a smoothing structure can make the film-sticking process of the light guide plate more convenient.

[0033] Among them, the transmission rod 10 is a screw rod, and when the control plate 9 moves along the outer wall of the transmission rod 10, the movable plate 8 will also slide on the outer wall of the guide plate 7. The coordinated use of the guide plate 7 and the movable plate 8 can prevent the control plate 9 from rotating simultaneously during the rotation of the transmission rod 10.

[0034] The fixed structure includes an extension plate 3 and a limit plate 4, the extension plate 3 is fixed to one end of the top side of the laminating table 1, the limit plate 4 is slidably installed on one end of the top side of the laminating table 1, and the side wall of the extension plate 3 is fixed with an electric telescopic rod, the telescopic end of the telescopic rod is fixedly connected to the side wall of the limit plate 4, after the light guide plate is placed on the top side of the placement rack 2, the side wall of the limit plate 4 can be driven to fit with the side wall of the light guide plate by starting the electric telescopic rod, and the fitting process of the limit plate 4 and the light guide plate can avoid the displacement of the light guide plate during the film pasting process, so that the film pasting effect of the light guide plate is better.

[0035] Electric telescopic rods and hydraulic telescopic rods can be selected from commonly used equipment on the market.

[0036] The fixed structure also includes a placement rack 2, which is fixed on the top side of the coating table 1. The placement rack 2 is a C-shaped structure. The open end of the placement rack 2 is located on one side of the limiting plate 4, and the top side of the placement rack 2 and the side wall of the limiting plate 4 are respectively installed with a buffer pad 11.

[0037] The placement rack 2 of the C-shaped structure can facilitate the placement process of the light guide plate. The setting of the opening portion of the C-shaped structure can facilitate the light guide plate to be placed on the top side of the placement rack 2 through its opening portion.

[0038] The lifting device includes a hydraulic telescopic rod, which is fixed to the bottom side of the control panel 9. The telescopic end of the hydraulic telescopic rod is fixedly connected to the top side of the connecting frame 5 through a connecting piece. By starting the hydraulic telescopic rod, the connecting frame 5 can be driven to move downward to make the bottom side of the smoothing cylinder 6 fit with the top side of the light guide plate to facilitate the rolling process of the smoothing cylinder 6.
