The adjusting rod 406 passes through the upper connecting plate 401 and is fixedly connected to a slider 404 provided on the upper connecting plate 401. The adjusting rod 406 slides in the upper connecting plate 401 to drive the slider 404 to slide on the guide rail 403, thereby driving the connecting rod 405 to rotate. The connecting rod 405 rotates to drive the upper connecting plate 401 to gradually move away from the lower connecting plate 402, thereby adjusting the detection height of the detection component 7 provided on the top of the height adjustment mechanism 4.
[0023] Furthermore, the detection component 7 includes a detector 701 and a detection lens 702. The detector 701 is fixedly mounted on the vertical plate 6.

The detector 701 transmits the detection signal to the control system. The control system detects and analyzes the LED display screen according to the received detection signal, thereby realizing comprehensive detection of the LED display screen and improving detection efficiency and accuracy.
[0024] Furthermore, the horizontal moving mechanism 8 includes a ball screw 801, a servo motor 802, a connecting block 803, a fixed rod 804 and a cushion block 805.

Vacuum absorbers 910 are fixedly installed at the corners of the carrier plate 909. The LED display screen is adsorbed on the carrier plate 909 by the vacuum absorber 910. At the same time, the support arm 906 can be driven to rotate by rotating the rotating shaft 905, thereby adjusting the angle of the carrier plate 909, so that the LED display screen can adapt to different detection angles, thereby improving the accuracy and comprehensiveness of the detection.
[0026] Furthermore, a connector 10 is embedded in the center of the carrier plate 909, and an electric telescopic rod 11 is fixedly connected to the side of the connector 10 away from the carrier plate 909. The electric telescopic rod 11 is fixedly installed on the connecting arm 908. The connector 10 is slidably connected to the carrier plate 909 through the electric telescopic rod 11.

[0027] The working principle of the utility model is as follows: when in use, firstly, the LED display screen is placed on the carrier plate 909, and the LED display screen is fixed by adsorption by the vacuum absorber 910, then, the angle of the carrier plate 909 is adjusted by rotating the rotating shaft 905 to adapt to different detection requirements, and then, the clamping mechanism 9 is moved to the detection position of the detection component 7 by the horizontal moving mechanism 8. At this time, by adjusting the height adjustment mechanism 4, the detection height of the detection component 7 can be adjusted to ensure that the detection lens 702 can accurately detect the LED display screen to be detected. During the detection process, the detector 701 transmits the detection signal to the control system, and the control system analyzes the LED display screen according to the received detection signal, thereby realizing a comprehensive detection of the LED display screen. In order to improve the efficiency and accuracy of the detection, before the detection, the electric telescopic rod 11 is extended and retracted to drive the connector 10 to move up and down in the carrier plate 909, so that the connector 10 is connected to the power supply end of the LED display screen to provide a stable power supply for the LED display screen. In this way, during the detection process, the stability and accuracy of the LED display screen can be ensured, thereby improving the detection effect.
