The first rotating gear 7 is movably connected to the first gear table 6, which drives the skateboard 8 to move smoothly along the first slide groove 5.

[0027] Specifically: a second slide groove 9 is provided on the slide plate 8, a first motor 10 is movably connected to the second slide groove 9, a detection device 19 is fixedly connected to the lower end of the first motor 10, a data cable 12 is fixedly connected to the upper end of the first motor 10, and a cable routing hole 11 is provided on the bracket plate 1, and the data cable 12 is movably connected in the cable routing hole 11 to ensure the neatness and safety of the data transmission line.

[0028] Specifically: A second gear platform 21 is fixedly connected to the side of the slide plate 8, and a second rotating gear 20 is movably connected to the first motor 10. The second rotating gear 20 is movably connected to the second gear platform 21 to improve detection efficiency.

[0029] Specifically: a control board 14 is movably connected to the upper end of the processing station 13, a display screen 15 is movably connected to the upper end of the processing station 13, and the other end of the data cable 12 is fixedly connected to the processing station 13 to ensure that the data can be accurately transmitted to the processing station 13 for processing.

[0030] Specifically: The lower end of the placement platform 2 is fixedly connected to multiple bases 3. The placement platform 2 is provided with a placement slot 16. The side of the placement slot 16 is provided with symmetrical pick-up slots 17. The placement slot 16 is provided with multiple clearance slots 18. An LCD screen 4 is movably connected inside the placement slot 16 to prevent damage to the LCD screen 4 due to squeezing or corner touch screen during the testing process.

[0031] Working principle:

[0032] First, place the LCD screen 4 stably in the placement slot 16 of the placement platform 2. The placement slot 16 is designed according to common LCD screen sizes to ensure compatibility. The side access slot 17 provides convenience for operators, facilitating easy handling and preventing damage to the LCD screen 4 due to improper operation. Multiple clearance slots 18 on the placement slot 16 provide space for the LCD screen 4's connection lines or protruding components, preventing damage during testing. Multiple bases 3 at the lower end of the placement platform 2 are made of rubber, which both reduces shock and increases friction with the ground, ensuring the stability of the placement platform 2. Upon activation of the test, the control board 14 on the processing table 13 issues a command to activate the second motor 22. The second motor 22 is fixed to the end of the slide plate 8, and its output shaft has a first rotating gear 7 meshing with a first gear platform 6 on the side of the first slide groove 5 inside the support plate 1. The second motor 22 operates, driving the first rotating gear 7 to rotate within the first gear platform 6, thereby driving the slide plate 8 to move smoothly along the first slide groove 5. The first slide groove 5 is made of surface-hardened stainless steel, ensuring smooth and stable movement of the slide plate 8. After the slide plate 8 moves to the predetermined position, the control board 14 issues another command to operate the first motor 10 in the second slide groove 9 on the slide plate 8. The first motor 10 is movably connected to the second slide groove 9 via a PTFE slider, reducing friction and improving stability. The detection device 19 connected to the lower end of the first motor 10 is configured with different probes according to the detection requirements, such as a high-resolution optical imaging probe to detect pixel defects. At the same time, the second gear platform 21 on the side of the slide plate 8 meshes with the second rotating gear 20 between the first motors 10. When the first motor 10 moves in the second slide groove 9, the second rotating gear 20 rotates in the second gear platform 21, ensuring that multiple first motors 10 move synchronously and improving detection efficiency. During the detection process, the data collected by the detection device 19 is transmitted through the data line 12 connected to the upper end of the first motor 10. The data line 12 is a shielded flexible cable to prevent electromagnetic interference. It passes through the chamfered cable routing hole 11 on the support plate 1 to ensure neat and safe wiring, and finally transmits the data to the processing table 13. The control board 14 on the processing station 13 quickly analyzes and processes the data, and the processing results are displayed on the display screen 15 in real time, which is convenient for operators to view and judge the quality of the LCD screen 4.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
