[0002] LED displays are a new type of information display medium. They are flat display screens composed of light-emitting diode dot matrix modules or pixel units. LED screens can convert between different forms of information presentation modes and can be used both indoors and outdoors, offering advantages that other displays cannot match. During the processing of LED displays, the finished LED displays need to be polished and trimmed to prevent burrs on the edges from scratching the workers' hands. Currently, the polishing of LED displays is mainly done by specialized polishing equipment.

[0003] Existing LED display screen grinding equipment requires manual adjustment after grinding one side of the display screen before grinding the remaining sides. This operation is very cumbersome and can usually only meet the grinding needs of LED displays of a single size. Utility Model Content

The top of the side plate 101 is fixedly connected to a mounting plate 304. The top of the mounting plate 304 is fixedly connected to a first telescopic cylinder 305. The bottom end of the first telescopic cylinder 305 is rotatably connected to an upper fixing plate 306.

[0022] A connecting bracket 307 is fixedly connected to the top of the main board 1, and a second servo motor 308 is fixedly connected to the side wall of the connecting bracket 307.

[0023] The output end of the second servo motor 308 is fixedly connected to the first threaded post 309, and the side wall of the first threaded post 309 is threadedly connected to the push plate 310.

[0024] It should be noted that: the display screen is placed directly on the surface of the lower fixed plate 303, and then the first telescopic cylinder 305 is driven to move the upper fixed plate 306 downward, fixing the display screen on the surface of the lower fixed plate 303. Then, the grinding component 2 can be used to grind the sides of the display screen. At the same time, the second servo motor 308 is driven to drive the first threaded post 309 to rotate. Using the threaded connection between the first threaded post 309 and the push plate 310, the push plate 310 is slid to the side of the display screen to hold the display screen in place for easy grinding. After one side is ground, the push plate 310 is moved away from the display screen, and the first servo motor 301 is driven to drive the first rotating shaft 302 to rotate. The first rotating shaft 302 drives the lower fixed plate 303 to rotate, thereby adjusting the position of the display screen. In this way, the grinding of all four sides of the display screen can be completed. It is simple and convenient and does not require manual adjustment.

[0025] Reference Figures 1-3 The grinding assembly 2 includes a second telescopic cylinder 201, which is fixedly installed on the side wall of the side plate 101, and a connecting box 202 is rotatably connected to the end of the second telescopic cylinder 201.

[0026] A third servo motor 203 is fixedly connected to the side wall of the connecting box 202, and a second threaded post 204 is fixedly connected to the output end of the third servo motor 203.

[0027] The second threaded post 204 has a connecting plate 205 threadedly connected to its side wall. The fourth servo motor 206 is fixedly connected to the top of the connecting plate 205. The output end of the fourth servo motor 206 is fixedly connected to the second rotating shaft. The side wall of the second rotating shaft is fixedly connected to the grinding roller 207.

[0028] It should be noted that: driving the second telescopic cylinder 201 causes the polishing roller 207 to fit against the side of the display screen. Subsequently, the fourth servo motor 206 can drive the second rotating shaft and the polishing roller 207 to rotate. The rotating polishing roller 207 can polish the display screen. The third servo motor 203 on the side wall of the connecting box 202 can be driven. The third servo motor 203 drives the second threaded post 204 to rotate. Utilizing the threaded connection between the second threaded post 204 and the connecting plate 205, the connecting plate 205 drives the rotating polishing roller 207 to slide, thereby polishing the entire edge of the display screen.

[0029] Reference Figures 1-3 The second telescopic cylinder 201 is fixedly connected to a mounting bracket 4 at its end, and a fifth servo motor 401 is fixedly connected to the side wall of the mounting bracket 4.

[0031] It should be noted that the fifth servo motor 401 drives the side wall of the mounting bracket 4. The fifth servo motor 401 drives the connecting column 402 to rotate through the third rotating shaft, thereby driving the connecting box 202 to rotate, and thus adjusting the angle of the grinding roller 207 to grind the side wall of the display screen. The debris generated during grinding will enter the inner cavity of the collection box 403.

[0032] Operation method: Place the display screen directly on the surface of the lower fixed plate 303, then drive the first telescopic cylinder 305 to move the upper fixed plate 306 down, fixing the display screen on the surface of the lower fixed plate 303. At the same time, drive the second servo motor 308 to drive the first threaded column 309 to rotate. Utilize the threaded connection between the first threaded column 309 and the push plate 310 to slide the push plate 310 to the side of the display screen and hold it against the display screen. Drive the second telescopic cylinder 201 to make the grinding roller 207 fit against the side of the display screen. Then, drive the fourth servo motor 206 to drive the second rotating shaft and the grinding roller 207 to rotate. The rotating grinding roller 207 can grind the display screen. The third servo motor 203 on the side wall of the connecting box 202 can be driven to drive the second threaded column 204 to rotate. Utilize the threaded connection between the second threaded column 204 and the connecting plate 205 to make the connecting plate 205 drive the rotating grinding roller 207 to slide, thereby grinding the entire edge of the display screen.

[0033] After one side is polished, the push plate 310 is moved away from the display screen, and the first servo motor 301 is driven to drive the first rotating shaft 302 to rotate. The first rotating shaft 302 drives the lower fixed plate 303 to rotate, thereby adjusting the position of the display screen. This completes the polishing of all four sides of the display screen. It is simple and convenient and does not require manual adjustment. The fifth servo motor 401 drives the side wall of the mounting bracket 4. The fifth servo motor 401 drives the connecting column 402 to rotate through the third rotating shaft, thereby driving the connecting box 202 to rotate, thereby adjusting the angle of the polishing roller 207 in order to polish the side wall of the display screen.
