[0026] Through the coordinated arrangement of the conveying platform 1, the backlight source 2, the conveyor belt 3, the limiting groove 4, the gantry 5, the first telescopic cylinder 6, the mounting plate 7, the connecting pipe 8, the suction cup 9 and the diaphragm 10 in the above structure, it is convenient to drive the mounting plate 7 to drive the diaphragm 10 to descend by the first telescopic cylinder 6 until the diaphragm 10 at the bottom of the suction cup 9 is aligned and abutted with the backlight source 2, and the diaphragm 10 is no longer sucked in, and the diaphragm 10 is attached to the backlight source 2 under the action of the back glue.

[0027] Embodiment 2

[0028] Based on the first embodiment, combined with the attached Figure 4 and Figure 5 , the mounting plate 7 is connected to a cleaning component for cleaning the backlight source 2 under the suction cup 9, the cleaning component includes a second telescopic cylinder 13 connected to both sides of the middle of the mounting plate 7, racks 14 are respectively connected to both sides of the power end of the second telescopic cylinder 13, gears 15 are respectively rotatably connected on the rod body of the second telescopic cylinder 13, the gears 15 are meshed with the racks 14, hinge rods 16 are coaxially provided on the gears 15, a cleaning roller 17 is connected relative to the hinge rods 16, the cleaning roller 17 is arranged below the diaphragm 10, the length of the cleaning roller 17 is greater than the width of the diaphragm 10, the cleaning roller 17 includes a hollow liquid storage shaft 18, the outer sleeve of the liquid storage shaft 18 is connected with a moisture-absorbing cotton 19, the liquid storage shaft 18 is evenly connected with a plurality of through holes 20 in the circumferential direction, the through hole 20 is connected with a plug 21 through a spring 22, the plug 21 is sealed with the through hole 20, one end of the plug 21 extends out of the liquid storage shaft 18

[0029] The arrangement of the cleaning component in the above structure facilitates pre-cleaning of the backlight source 2, thereby preventing bubbles and the like from appearing due to dust and other debris on the surface of the backlight source 2.

[0030] The specific usage is as follows:

[0031] First, place the backlight source 2 in the limiting groove 4 to facilitate positioning of the backlight source 2;

[0032] Then, the conveyor belt 3 drives the backlight source 2 body intermittently to move it one by one to the bottom of the gantry 5, so that the backlight source 2 is aligned with the film 10, which is convenient for film application;

[0033] Next, the mounting plate 7 is driven to descend by the first telescopic cylinder 6. When the cleaning component abuts against the backlight source 2, the second telescopic cylinder 13 is driven to slowly stretch. The second telescopic cylinder 13 drives the hinge rod 16 through the meshing of the rack 14 and the gear 15 to drive the cleaning rollers 17 on both sides to move away from each other, and cooperates with the descent of the first telescopic cylinder 6 to make the cleaning rollers 17 always abut against the backlight source 2, thereby facilitating the cleaning of the backlight source 2. The liquid storage shaft 18 is filled with volatile cleaning liquid.

At this time, the spring 22 stretches and accumulates force, and the cleaning liquid is transmitted to the moisture-absorbing cotton 19 through the gap between the through hole 20 and the plug 21, and then the surface of the backlight source 2 is cleaned by the moisture-absorbing cotton 19.

[0034] Finally, the mounting plate 7 is driven to descend by the first telescopic cylinder 6 to avoid relative rotation caused by the telescopic movement of a single telescopic cylinder and affect the alignment accuracy, so as to improve the stability of the lifting and lowering of the mounting plate 7. The mounting plate 7 uses the suction cup 9 on the connecting tube 8 to suck and position the diaphragm 10 until the diaphragm 10 at the bottom of the suction cup 9 is aligned and abutted with the backlight source 2, so as to facilitate the film sticking operation. The external negative pressure component sucks air into the air vent 12 so that the two suction cups 9 have suction at the same time, so as to facilitate the suction of the diaphragm 10. When the diaphragm 10 moves down to the backlight source 2, the negative pressure is released and the diaphragm 10 is no longer sucked, so as to facilitate the adhesion of the diaphragm 10 to the backlight source 2 under the action of the back glue.
