There is a reset spring 7, and a gear 9 is rotatably installed at the bottom of the inner side of the column 4. A rotating rod 10 is installed at the middle position of the side of the gear 9. The rotating rod 10 is rotatably connected to the column 4, and a rocker 11 is vertically installed at the end of the rotating rod 10 away from the gear 9. A first rack 12 is meshed at the bottom of the gear 9, and the first rack 12 is fixed to the side of the support plate 2 along the length direction of the support plate 2. A second rack 13 is meshed on the outer side of the gear 9, and the second rack 13 is vertically installed on the cross plate 6. A multimeter 14 is provided between the two groups of columns 4.

[0025] General working principle: Before use, place the LCD display module on the top of the support plate 2, and use the limit mechanism 3 to position it to ensure the stability of the position of the LCD display module, and then adjust the position of the detection probe on the horizontal plate 6 according to the position of the positive and negative poles on the LCD display module to ensure that the detection probe is directly above the positive and negative poles, and then use the clamping mechanism 8 to stabilize the position of the detection probe. During detection, hold the rocker 11 and press down to control the rotation of the gear 9. The gear 9 is engaged with the first rack 12 and the second rack 13. Therefore, during the rotation of the gear 9, the LCD display module is controlled to move toward the bottom of the detection probe. At the same time, the detection probe moves vertically downward to contact the positive and negative poles on the LCD module for detection. The detection value is observed through the multimeter 14. After the detection is completed, lift the rocker 11. At this time, the support plate 2 pushes the LCD display module outward, and then removes it to load another group. Repeat the above operation and continue to detect.

[0026] In this embodiment, connecting rods are provided between the two sides of the multimeter 14 and the inner wall of the column 4 , and the connecting rods are rotatably connected to the column 4 .

[0027] Partial working principle: During the detection process, the multimeter 14 is driven to rotate by controlling the connecting rod so as to perform vertical observation on the multimeter 14, which is more convenient to use.

[0028] In this embodiment, an anti-skid pad having the same surface area as the base 1 is provided at the bottom of the base 1 , and anti-skid patterns are provided at the bottom of the anti-skid pad.

[0029] Partial working principle: When the device is placed on a workbench, the anti-skid pad at the bottom of the base 1 improves the placement stability of the device.

[0030] In this embodiment, the rocker 11 is disposed perpendicular to the horizontal plane, and a rubber grip is fixed to the top of the rocker 11 .

[0031] Partial working principle: When controlling the rotation of the gear 9, holding the rubber grip on the rocker 11 makes the hand more stable.

[0032] In this embodiment, the limiting mechanism 3 includes an L-shaped plate 15, a positioning screw 16, a strip groove 17 and a slider 18. The L-shaped plate 15 is symmetrically arranged on both sides of the support plate 2. The positioning screws 16 are threadedly installed on the L-shaped plate 15. A strip groove 17 is opened on the top of the support plate 2 along the width direction. Sliders 18 are slidably provided at both ends of the strip groove 17. The two groups of sliders 18 are fixedly connected to the L-shaped plate 15 respectively.

[0033] Local working principle: Since the lengths of the LCD display modules are different, when performing batch inspection, the LCD display modules are first placed between the two groups of L-shaped plates 15 on the top of the pallet 2, and the two groups of L-shaped plates 15 are controlled to slide and fit with the right-angle ends of the LCD display modules, and then the positioning screws 16 are tightened to stabilize the positions of the two groups of L-shaped plates 15. Therefore, during the inspection of the LCD display modules, the LCD display modules can be quickly positioned.

[0034] In this embodiment, the clamping mechanism 8 includes a through slot 19, an extrusion plate 20 and an extrusion bolt 21. The through slot 19 is opened on the transverse plate 6 and is arranged along the length direction of the transverse plate 6. An extrusion plate 20 is provided between the two ends of the through slot 19. The extrusion plate 20 slides along the width direction of the through slot 19. An extrusion bolt 21 is rotatably installed at the middle position of one side of the transverse plate 6. One end of the extrusion bolt 21 extends to the inside of the through slot 19 and is rotatably connected to the extrusion plate 20.

[0035] Local working principle: When adjusting the position of the test lead, control the test lead to slide along the length direction of the through slot 19 to ensure that the spacing between the test leads is the same as the spacing between the positive and negative poles of the liquid crystal display module and is located above the positive and negative poles. Then rotate the extrusion bolt 21 and push the extrusion plate 20 to extrude and fix the test lead.

[0036] In this embodiment, a rubber pad is provided on one side of the extrusion plate 20 away from the extrusion bolt 21 , and the length of the rubber pad is the same as the length of the extrusion plate 20 .

[0037] Partial working principle: During the extrusion process of the extrusion plate 20, the rubber pad contacts and deforms with the outer side of the detection probe, and adheres to the outer side of the detection probe, thereby increasing the extrusion stability of the detection probe.
