[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3As shown, the embodiment of the utility model provides a detection device for LCD patch processing, including:

[0021] U-shaped bracket 1;

[0022] Detection component; The detection component includes two conveying mechanisms that rotate synchronously and are spaced and installed on a U-shaped bracket 1. The conveying mechanism includes two transmission rollers 15 that rotate on the U-shaped bracket 1. The two transmission rollers 15 are connected by a conveyor belt 10. Two transmission rollers 15 that are close to the two conveying mechanisms are both installed with transmission wheels 11. The two transmission wheels 11 are connected by a belt 12. A motor 2 is installed on the U-shaped bracket 1. The output end of the motor 2 is coaxially fixedly connected to one of the transmission rollers 15. The motor 2 drives the transmission roller 15 to rotate when it works, so that the conveyor belt 10 can be rotated. Under the transmission of the transmission wheel 11 and the belt 12, the two conveyor belts 10 can rotate synchronously, and the LCD patch can be transported;

[0023] Two fixing plates 4 are fixed on the U-shaped bracket 1, and a first screw rod 7 is rotatably connected to the fixing plate 4. A second screw rod 8 rotatably connected to the fixing plate 4 is fixed to the other end of the first screw rod 7, and a handle 3 is fixed to the second screw rod 8; two sliders 5 threadedly connected to the first screw rod 7 and the second screw rod 8 are sleeved on the outside of the first screw rod 7 and the second screw rod 8, and the first screw rod 7 and the second screw rod 8 are rotated by rotating the handle 3. Since the thread directions of the first screw rod 7 and the second screw rod 8 are arranged in opposite directions, and a guide rod 6 is fixed between the two fixing plates 4, and the guide rod 6 passes through the two sliders 5 and is slidably arranged with them, the two limited sliders 5 move relative to or away from each other;

[0024] A guide plate 9 is fixed at the bottom of the slider 5. The movement of the slider 5 drives the guide plate 9 to move, so that the distance between the two guide plates 9 can be controlled, and LCD patches of different widths can be guided. The LCD patches being transported can be stably transported through the guide plates 9; a polytetrafluoroethylene film is fixed on the opposite side of the two guide plates 9, and the friction of the guide plates 9 on the LCD patches can be reduced by setting the polytetrafluoroethylene film;

[0025] The U-shaped bracket 1 is fixed with an electric push rod 13 located between the two conveying mechanisms, and an illuminating lamp 14 is fixed at the output end of the electric push rod 13, and the height of the illuminating lamp 14 can be adjusted by the electric push rod 13; when the LCD patch is conveyed by the conveyor belt 10 and passes over the illuminating lamp 14, the conveyed LCD patch can be illuminated and tested by the illuminating lamp 14, and the staff only needs to remove the defective LCD patch with scratches, and other qualified LCD patches continue to be conveyed; the output end of the electric push rod 13 is fixed with a mounting block, and the illuminating lamp 14 can be detachably mounted on the mounting block, and can be installed by bolts and the like. The purpose of disassembling the illuminating lamp 14 is to facilitate the replacement of different illuminating lamps 14 according to LCD patches of different sizes, so as to avoid the light of the illuminating lamp 14 that is too long and leaks out to affect the staff;

[0026] As mentioned above, the utility model can be used in conjunction with an assembly line to detect LCD patches, and can guide the LCD patches to ensure the stability of the detection, and can detect LCD patches of different models, with high efficiency and good practicality.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
