[0027] Please refer to Figures 1 to 3 , which is a display screen handling device in the embodiment of the present utility model, used for handling a display screen, and includes a handling suction plate 10 and an adsorption assembly.

[0028] Among them: The handling suction plate 10 is connected to a vacuum pump. The display screen includes a connected substrate and a circuit board 22. The handling suction plate 10 is used to adsorb the substrate. When the substrate is adsorbed by the handling suction plate 10, the substrate is suspended in the air, and the circuit board 22 naturally hangs down. There are not only problems with partial bending of the circuit board 22, but also risks of being crushed and scratched during handling. To solve the above problems, an adsorption assembly is provided on the handling suction plate 10. The adsorption assembly includes an adjustment structure and an adsorbing member. The adjustment structure is used to adjust the position of the adsorbing member to meet the adsorption requirements of different types of display screens. The adsorbing member is connected to the handling suction plate through the adjustment structure. The adsorbing member is used to adsorb and lift the circuit board 22 so that the circuit board 22 and the substrate are parallel, improving the problems of bending, crushing, or scratching of the circuit board 22 caused by the natural drooping of the circuit board 22, which is beneficial to improving the product yield. It should be noted that the handling suction plate 10 is a prior art and will not be elaborated here.

[0029] In this embodiment, the adjustment structure includes a first sheet metal part 311, a second sheet metal part 312, and a displacement member. The first sheet metal part 311 is connected to the surface of the handling suction plate 10, and the first sheet metal part 311 is connected to the second sheet metal part 312 through the displacement member. The only key is used to drive the second sheet metal part 312 to approach or move away from the handling suction plate 10. Specifically, the displacement member includes a screw 313, a displacement block 314, and a servo motor 315. A displacement groove 311a is formed on the first sheet metal part 311. The screw 313 is arranged in the displacement groove 311a, and the screw 313 is rotatably connected to the first sheet metal part 311. The displacement block 314 is sleeved on the screw 313, and the displacement block 314 is threadedly connected to the screw 313. The displacement block 314 is connected to one end of the second sheet metal part 312. The drive shaft of the servo motor 315 is fixedly connected to one end of the screw 313, and the servo motor 315 is installed on the surface of the handling suction plate.

[0030] It can be understood that when the servo motor 315 works, it drives the screw 313 to rotate. At this time, the displacement block 314 moves along the length direction of the screw 313 as the screw 313 rotates. In order to limit the rotation of the displacement block 314 as the screw 313 rotates, the side wall of the displacement block 314 is brought into close contact with the groove wall of the displacement groove 311a to realize the translation of the displacement block 314 as the screw 313 rotates.

[0031] It should be noted that a transmission shaft is connected to the drive shaft of the servo motor 315. A through groove is formed on the first sheet metal part 311. The end of the transmission shaft away from the servo motor 315 passes through the through groove and is fixedly connected to the screw 313. The through groove is communicated with the displacement groove 311a. Among them, both the first sheet metal part 311 and the second sheet metal part 312 are plate-like structures. The first sheet metal part 311 and the second sheet metal part 312 are perpendicular to each other. One end of the first sheet metal part 311 extends out of the handling suction plate 10, and the second sheet metal part 312 is located on one side of the handling suction plate 10.

[0032] In this embodiment, a plurality of clamping structures are provided on the second sheet metal part 312. The clamping structures are used to clamp the adsorption part, realizing the detachable connection between the adsorption part and the second sheet metal part 312. A long slot 312a is formed in the second sheet metal part 312, and the plurality of clamping structures are evenly distributed at equal intervals along the length direction of the long slot 312a. The long slot 312a is located on the top surface and the bottom surface of the second sheet metal part 312 that are opposite to each other.

[0033] It should be noted that the clamping structure includes a clamping plate 317 and a stud 316. A threaded hole is formed in the second sheet metal part 312, and the threaded hole communicates with the long slot 312a. One end of the stud 316 is connected to the clamping plate 317 through the threaded hole. The clamping plate 317 is located in the long slot 312a. The stud 316 is threadedly connected to the threaded hole. A fixing plate 318 is arranged in the long slot 312a, and the fixing plate 318 is opposite to the clamping plate 317 in position. An auxiliary rotating head is connected to the end of the stud 316 away from the clamping plate 317. The auxiliary rotating head is used to assist manual rotation of the stud 316, so that the stud 316 is screwed into or withdrawn from the threaded hole, thereby reducing or increasing the distance between the clamping plate 317 and the fixing plate 318. The adsorption part is placed between the clamping plate 317 and the fixing plate 318 to realize the fixation or loosening of the adsorption part.

[0034] In this embodiment, the fixing plates 318 are all arc-shaped structures, and the concave surfaces of the clamping plates 317 and the fixing plates 318 are arranged opposite to each other to realize the fitting contact between the concave surfaces of the arc-shaped structures and the adsorption part.

[0035] It can be understood that the position of the adsorption part is adjusted according to the size of the circuit board 22 in the display screen. After the adsorption part is placed at an appropriate position, the clamping structure is used for clamping and fixing.

[0036] In this embodiment, the adsorption part includes a suction nozzle 32 and a vacuum pump. The suction nozzle 32 is connected to the vacuum pump through a vacuum tube. A vacuum valve is arranged on the vacuum tube, and the vacuum valve is used to control the flow state of the vacuum tube. The suction nozzle 32 is a cylindrical structure. The suction nozzle 32 is placed between the clamping plate 317 and the fixing plate 318. By tightening the stud 316, the suction nozzle 32 is fixed. The suction nozzle 32 and the handling suction plate 10 share a vacuum pump. When the display screen is adsorbed by the display screen handling device, the vacuum valve on the vacuum tube is closed, and the substrate is adsorbed by the handling suction plate 10. Then the vacuum valve is opened, and the circuit board 22 is manually lifted, so that the suction nozzle 32 adsorbs and lifts the circuit board 22 to make the circuit board 22 parallel to the substrate.

[0037] In specific implementation, by providing an adsorption assembly on the handling suction plate 10, connecting the adsorbing member to the handling suction plate 10 by means of the adjusting structure in the adsorption assembly, and adsorbing the circuit board 22 by the adsorbing member, the circuit board 22 is made parallel to the substrate, thus improving the problems of bending, pressing damage or scraping off of the circuit board 22 caused by the natural drooping of the circuit board 22, which is beneficial to improving the product yield. At the same time, the position of the adsorbing member is adjusted by using this adjusting structure, which is applicable to more types of display screens and expands the product application range.

[0038] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the display screen handling device of the present application has only the above-mentioned unique implementation process. On the contrary, as long as the display screen handling device of the present application can be implemented, it can be incorporated into the feasible implementation schemes of the present application.
