[0025] When the device needs to be used, the operator should first wear gloves to prevent damage to the liquid crystal display during operation, then place the liquid crystal display to be tested in the middle of the top of the base 1 and fix it using the clamping mechanism composed of the first electric sliding block 6, the second electric sliding rail 8 and the clamping block 7, ensuring that the clamping block 7 made of soft rubber material will not damage the screen surface, while adapting to screens of different sizes. According to the size of the liquid crystal display, the position of the first electric sliding rail 5 and the second electric sliding rail 8 is adjusted by the control system to accurately position and firmly fix the liquid crystal display. The operator turns on the power of the equipment, then starts the preset detection program. At this time, the electric push rod 12 will automatically adjust the height of the frame one 2 according to the setting to ensure that the liquid crystal display is in the best detection position. After the preset program is started, the servo motor 19 will automatically drive the worm gear 18 and the worm 20 transmission system to rotate the frame two 3 through the connecting shaft 4, so as to detect the liquid crystal display from different angles (including front and back). Since the worm gear 18 and the worm 20 transmission has self-locking characteristics, it can ensure the stability after angle adjustment. The protective shell 21 protects the worm gear 18, the servo motor 19 and the worm 20 from the influence of the external environment, prolonging the service life of the key components. The first detector 11 starts to work to measure the brightness, color uniformity and other key indicators of the liquid crystal display. If more detailed analysis is needed, the second detector 17 on the third electric sliding rail 15 can be used to accurately detect specific areas. All detection data will be automatically recorded and can be analyzed later through the connected computer system to help identify any potential quality problems or performance deviations. After all the detection is completed, turn off the power of the equipment, loosen the clamping block 7 and take out the tested liquid crystal display. If other samples need to be detected, the above steps can be repeated. To reduce friction and improve wear resistance, the first electric sliding block 6, the second electric sliding block 9 and the third electric sliding block 16 are all made of engineering plastic material, which helps to improve the running efficiency and service life of the whole system.
