When in use, the LED display screen is placed on the upper end of the mobile platform, and then the two first motors are started at the same time to drive the gears to rotate. Since the gears are meshed with the racks, the mobile platform and the LED display screen on its upper end can be driven to move horizontally under the action of the racks when the gears rotate. The track wheels and track grooves can make the mobile platform more stable when moving horizontally, with high practicality and convenient and quick operation.
[0016] 2. The test equipment for processing LED display screens can drive the first screw rod, the connecting tube and the second screw rod to rotate simultaneously through the second motor, thereby driving the two first moving blocks to move toward the center position, thereby driving the two clamping plates to clamp the LED display screen on the upper end of the moving table, thereby preventing the LED display screen from slipping off and being damaged from the upper end of the moving table when the moving table moves. The spring provided can prevent the LED display screen from being deformed and damaged due to a large clamping force when clamping the LED display screen.

The cleaning roller can be driven to rotate by the provided third motor, so that the surface of the LED display screen can be efficiently cleaned. When in use, the moving platform drives the LED display screen to move directly below the cleaning roller, and then the moving frame and the cleaning roller are pushed downward by the cylinder until the cleaning roller fits the surface of the LED display screen, and then the cleaning roller is driven to rotate by the third motor, and at the same time, the moving platform continues to move to drive the LED display screen to move. When the cleaning roller rotates, the surface of the LED display screen can be cleaned, which solves the problem that the dust and impurities on the surface of the LED display screen affect the subsequent test results. The system has high practicality and is convenient and quick to operate.

[0031] like Figure 1 , Figure 6 , Figure 7 , Figure 8As shown, a test device for processing an LED display screen has two vertical plates 42 welded on the upper end of a support table 1, wherein a fourth motor 43 is detachably connected to the top of one of the vertical plates 42, and the output end of the fourth motor 43 is detachably connected to a third screw rod 44 through a coupling, and a first guide rod 45 is welded inside the other vertical plate 42, and the third screw rod 44 is threadedly connected to the outer surface of the first guide rod 45 and is slidably connected to a second moving block 46, and a third connecting plate 47 is welded to one side of the two second moving blocks 46, and a U-shaped cover 48 is welded between the two third connecting plates 47, and a fixed frame 49 is welded to the top of the U-shaped cover 48, and a fifth motor 50 is detachably connected to one end of the fixed frame 49, and the output end of the fifth motor 50 passes through the fixed frame 49 through The coupling is set up and is detachably connected to the fourth screw rod 51.

The output end of the sixth motor 54 passes through the connecting frame 53 and is detachably connected to the fifth screw rod 55 through the set coupling. A second guide rod 56 is welded inside the connecting frame 53. The outer surfaces of the fifth screw rod 55 and the second guide rod 56 are provided with a fourth moving block 57. The fourth moving block 57 is threadedly connected to the outer surface of the fifth screw rod 55. The fourth moving block 57 is slidably connected to the outer surface of the second guide rod 56.

By driving the fifth screw rod 55 to rotate through the sixth motor 54, the fourth moving block 57 can be driven to move left and right, and the brightness meter 58 can be driven to move left and right at the same time.

[0033] It should be noted that the present invention is a testing device for processing LED display screens. When in use, the LED display screen to be tested is placed on the upper end of the moving platform 8, and then the second motor 15 is started to drive the first screw rod 16, the connecting tube 17, and the second screw rod 18 to rotate. At this time, the two first moving blocks 19 will drive the two moving plates 20 to move toward the center position as the first screw rod 16 and the second screw rod 18 rotate, and at the same time drive the two clamping plates 25 to move. After the two clamping plates 25 clamp the LED display screen, the multiple springs 23 will be compressed, which can effectively avoid the situation where the LED display screen is deformed and damaged due to the large force when the two clamping plates 25 clamp the LED display screen. At the same time, under the elastic force of the spring 23, the two clamping plates 25 can stably clamp the LED display screen; After the LED display screen is stably clamped, the two first motors 10 are started to drive the two gears 11 to rotate. At this time, the moving platform 8 drives the clamped LED display screen to move horizontally under the action of the rack 6. Here, during the movement, the multiple track wheels 14 slide horizontally in the track groove 5 to ensure the stability of the movement of the moving platform 8. After the moving platform 8 drives the LED display screen to move to the position directly below the cleaning roller 32, the cylinder 27 pushes the moving frame 29 and the cleaning roller 32 to move downward until the cleaning roller 32 is in contact with the surface of the LED display screen, and then the third motor 31 is started to drive the cleaning roller 32 to rotate, and then the first motor 10 is started to continue to drive the moving platform 8 and the LED display screen to move. When the display screen moves, the cleaning roller 32 cleans its surface. When cleaning, the air pump 33 is started, and the dust impurities raised can be adsorbed through the exhaust pipe 34 and the exhaust head 35. At the same time, the dust impurities can be input into the purification box 37 through the air supply pipe 36, and then discharged through the exhaust port 41 after being filtered and purified by the filter screen 39 and the activated carbon adsorption plate 40, which effectively avoids the dust generated during cleaning from directly floating into the air and polluting the working environment. After the surface of the LED display screen is cleaned, the moving platform 8 drives the LED display screen to continue to move. After the moving platform 8 moves to the bottom of the U-shaped cover 48, the third screw rod 44 is driven to rotate by the fourth motor 43. At this time, the second moving block 46 will drive the third connecting plate 47 and the U-shaped cover 48 to move downward with the rotation of the third screw rod 44, until the two third connecting plates 47 are respectively inserted into the two rectangular grooves 59 opened on the surface of the moving platform 8. At this time, the surface of the moving platform 8 will be completely covered by the third connecting plate 47 and the U-shaped cover 48, and the inside of the moving platform 8 will be in a dark state. At this time, the LED display screen is turned on and then the brightness is tested by the brightness meter 58. During the test, the fourth screw rod 51 is driven to rotate by the fifth motor 50 to drive the third moving block 52, the connecting frame 53 and the brightness meter 58 to move forward and backward. At the same time, the fifth screw rod 55 is driven to rotate by the sixth motor 54 to drive the fourth moving block 57 and the brightness meter 58 to move left and right, so that the brightness meter 58 can be driven to move to different positions above the LED display screen for brightness testing, and then the values obtained from the brightness tests at different positions are compared to know whether the display screen is normal.
