[0021] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a film pasting device for processing an LED backlight module, comprising a bracket 1, a fixing plate 2 is fixedly connected to the upper surface of the bracket 1, a motor 3 is fixedly connected to the lower surface of the fixing plate 2, a turntable 4 is fixedly connected to the output end of the motor 3, a plurality of limiting rollers 5 are fixedly connected to the upper surface of the turntable 4, and a connecting component 6 is arranged on the outer wall of the limiting roller 5.

[0022] The upper surface of the fixed plate 2 is fixedly connected with a plurality of limit blocks 8, and a rack 7 is slidably connected inside the limit block 8. A support 9 is fixedly connected to the side away from the limit block 8, and a rotating shaft 10 is rotatably connected inside the support 9. A gear 11 is fixedly connected to the outer wall of the rotating shaft 10, and the gear 11 is meshed with the rack 7.

[0023] The outer wall of the rotating shaft 10 is fixedly connected with a special-shaped frame 12 , the interior of the special-shaped frame 12 is rotatably connected with a rotating plate 13 , and a film sticking machine 14 is arranged on the lower surface of the rotating plate 13 .

[0024] The connecting assembly 6 includes an arc plate 601, which is rotatably connected to the outer wall of the limiting roller 5. The outer wall of the arc plate 601 is rotatably connected to a hinge seat 602, and one side of the outer wall of the hinge seat 602 is fixedly connected to one side of the outer wall of the rack 7.

[0025] Start the motor 3 to drive the turntable 4 to rotate. The rotation of the turntable 4 is transmitted through the hinge seat 602 on the outer wall of the arc plate 601 on the outer wall of the limiting roller 5, thereby realizing the driving of the rack 7. The rack 7 is engaged with the gear 11, so that the gear 11 can rotate. The rotation of the gear 11 further drives the special-shaped frame 12 on the outer wall of the rotating shaft 10 to descend. The special-shaped frame 12 cooperates with the rotating plate 13, so that the film laminating machine 14 can move along the direction of the rotating plate 13. The film laminating machine 14 can perform film laminating operations on multiple groups of LED backlight modules, thereby achieving the effect of performing film laminating operations on multiple groups of LED backlight modules at a time.

[0026] Reference Figure 1 , Figure 2 and Figure 3The upper surface of the film laminating machine 14 is fixedly connected with a limit rod 15, and the outer wall of the limit rod 15 is slidably connected to the inside of the rotating plate 13. The outer wall of the limit rod 15 is sleeved with a return spring 16. The upper end of the return spring 16 is fixedly connected to the lower surface of the rotating plate 13. The lower surface of the return spring 16 is fixedly connected to the upper surface of the film laminating machine 14.

[0027] The upper surface of the fixed plate 2 is fixedly connected with a plurality of gears 11. A push plate 18 is fixedly connected to one side of the outer wall of the rack 7. The outer wall of the rack 7 is slidably connected with a second limit block 17. The lower surface of the second limit block 17 is fixedly connected to the upper surface of the fixed plate 2. A material discharge chute 20 is fixedly connected to the side away from the plurality of second limit blocks 17.

[0028] The upper surface of the unloading chute 20 is fixedly connected with an anti-skid pad 21, and the anti-skid pad 21 is fixedly connected directly below the film laminating machine 14. A limiting groove 22 is provided through the inside of the unloading chute 20. A collection box 23 is fixedly connected to one side of the outer wall of the unloading chute 20.

[0029] The outer wall of the push plate 18 is fixedly connected with a sliding rod 19 , and the sliding rod 19 is slidably connected to the inner wall of the limiting groove 22 .

[0030] The LED backlight module is placed on the surface of the anti-slip mat 21 to prevent sliding or displacement during operation. The laminating machine 14 descends and applies pressure on the upper surface of the LED backlight module. In this process, the action of the laminating machine 14 not only presses the module, but also pushes the limit rod 15 to slide inside the rotating plate 13. The limit rod 15 plays a guiding and limiting role to ensure that the descending action of the laminating machine 14 is properly controlled. The sliding of the limit rod 15 will also drive the reset spring 16 to contract. The reset spring 16 plays a protective role, preventing the laminating machine 14 from applying excessive pressure to the LED backlight module, thereby avoiding possible damage to the module.

[0031] After the film laminating operation is completed, the rack 7 can slide between the limit block 1 8 and the limit block 2 17. When the rack 7 is reset, it will drive the gear 11 to reverse, so that the laminating machine 14 can slowly rise and remove the pressure on the LED backlight module. This continuous action not only ensures the safety of the module, but also prepares for the next operation; finally, the continued movement of the rack 7 drives the push plate 18 to push the LED backlight module on the anti-slip pad 21 through the unloading chute 20 into the collection box 23 for collection. The push plate 18 uses mechanical principles to ensure that the module can be smoothly and accurately sent to the collection box 23, thereby completing the entire collection process.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
