[0031] The moving assembly 4 comprises a mounting box 41 fixedly installed on the upper surface of the workbench 1, the mounting box 41 is symmetrically provided with two groups, and a second motor 42 fixedly installed on one side of one group of mounting boxes 41, the output end of the second motor 42 is provided with a first lead screw 43, the outer surface of the first lead screw 43 is threadedly connected with a first moving block 431, the inside of the other group of mounting boxes 41 is provided with a first guide rod 44, the outer surface of the first guide rod 44 is slidably connected with a first guide block 441, the upper surfaces of the first moving block 431 and the first guide block 441 are provided with a mounting bracket 45, the upper surface of one group of mounting brackets 45 is provided with a third motor 46, the output end of the third motor 46 is fixedly installed with a second lead screw 47, the outer surface of the second lead screw 47 is threadedly connected with a second moving block 471, the inside of the other group of mounting brackets 45 is provided with a second guide rod 48, the outer surface of the second guide rod 48 is slidably connected with a second guide block 481, a motorized slide rail 49 is arranged between the second moving block 471 and the second guide block 481, one side of the motorized slide rail 49 is slidably connected with a connecting bracket 491, the second motor 42 drives the first lead screw 43 to rotate, the first moving block 431 on the first lead screw 43 moves along the direction of the first lead screw 43, at the same time, the first guide block 441 on the first guide rod 44 in the other group of mounting boxes 41 plays a guiding role, ensuring the linear motion of the first moving block 431, therefore the two groups of mounting brackets 45 move, and because the third motor 46 drives the second lead screw 47 to rotate, the second moving block 471 on the second lead screw 47 moves along the direction of the second lead screw 47, the second guide block 481 on the second guide rod 48 plays a guiding role, therefore the motorized slide rail 49 between the second moving block 471 and the second guide block 481 can move up and down, and then the connecting bracket 491 slides on one side of the motorized slide rail 49, so as to realize the multi-directional movement of the detecting assembly 3, improving the comprehensiveness of detection.

[0032] The detection assembly 3 comprises a detection box 31 threadedly connected on one side of the connecting frame 491, and an electric telescopic detection rod 32 arranged at the bottom of the detection box 31, and the telescopic end of the electric telescopic detection rod 32 is provided with a photosensitive detection assembly 33, so that the electric telescopic detection rod 32 can adapt to LED screens of different heights, and the distance from the LED screen can be adjusted according to the detection requirement, thereby improving the flexibility and accuracy of detection.

[0033] The upper surface of the workbench 1 is provided with a light shield 5, and a movable door 51 is hinged on one side of the light shield 5, so that the light shield 5 can reduce the interference of external light on the detection result of the photosensitive detection assembly 33, and ensure the accuracy of the detection data, and the movable door 51 can provide a relatively closed environment during detection without affecting the normal use of the equipment.

[0034] One side of the movable door 51 is provided with a control panel 6, and the photosensitive detection assembly 33 is signal connected with the control panel 6, so that the operator can operate the equipment outside the equipment through the control panel 6, and can obtain the detection data in time, and analyze the detection result.

[0035] Specifically, the first motor 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the disc 23 to rotate. Since the disc 23 is provided with the placing disc 24 through the support column 231, the LED screen is placed on the upper surface of the placing disc 24, and then the vacuum pump 252 is started to extract the air in the vacuum suction disc 25 through the connecting pipe 251 by the vacuum pump 252, so as to fix the LED screen. Different sizes of LED screens can be fixed, so as to improve the accuracy of the detection result, and the subsequent detection assembly 3 can be conveniently detected more comprehensively, and the detection efficiency is improved. The motor 27 drives the double-threaded rod 28 to rotate. Since the double-threaded rod 28 has a right thread and a reverse thread, the two groups of sliding blocks 29 connected with it by threads will move towards or away from each other. Then the electric push rod 291 on the sliding block 29 can be telescopic, so as to drive the pressing block 292 to press the LED screen, so as to further fix it. And since one side of the pressing block 292 is provided with the silica gel plate 293, the silica gel plate 293 can avoid scratching the LED screen by the pressing block 292.

At the same time, the first guide block 441 on the first guide rod 44 in the other group of mounting boxes 41 plays a guiding role, so as to ensure the linear motion of the first moving block 431. Therefore, the two groups of mounting frames 45 move. Because the third motor 46 drives the second lead screw 47 to rotate, the second moving block 471 on the second lead screw 47 will move along the direction of the second lead screw 47. The second guide block 481 on the second guide rod 48 plays a guiding role, so as to drive the electric sliding rail 49 between the second moving block 471 and the second guide block 481 to move up and down. Then the connecting frame 491 slides on one side of the electric sliding rail 49, so as to realize the multi-directional movement of the detection assembly 3, improve the comprehensiveness of the detection, and the detection assembly 3 can adapt to LED screens of different heights by the electric telescopic detection rod 32, and can adjust the distance from the LED screen according to the detection requirement, improve the flexibility and accuracy of the detection. In addition, since the upper surface of the workbench 1 is provided with the light shield 5, one side of the light shield 5 is hinged with the movable door 51, so that the light shield 5 can reduce the interference of external light on the detection result of the light-sensitive detection assembly 33, and ensure the accuracy of the detection data. The movable door 51 can provide a relatively closed environment without affecting the normal use of the equipment. Since one side of the movable door 51 is provided with the control panel 6, the light-sensitive detection assembly 33 is signal connected with the control panel 6, so that the operator can operate the equipment outside through the control panel 6, and can obtain the detection data in time, and analyze the detection result.
