[0007] The bottom of the leg is provided with a roller. The setting of the roller makes the whole inspection bench can be easily moved between different positions, improves the flexibility and convenience of the inspection bench.

[0008] The reinforcing plate is arranged between the workbench and the supporting legs, and can enhance the connection strength between the workbench and the supporting legs, thereby improving the stability of the whole inspection table.

[0009] The detection device includes a second driving mechanism, a third driving mechanism, a second support plate, a support frame, and a camera. The second driving mechanism is arranged on the workbench, the third driving mechanism is coupled with the output end of the second driving mechanism through the second support plate, the second driving mechanism can drive the second support plate to rotate in the horizontal direction, the camera is coupled with the output end of the third driving mechanism through the support frame, and the third driving mechanism can drive the support frame to move close to or away from the positioning device. The second driving mechanism and the third driving mechanism allow the second support plate to rotate in the horizontal direction, and the camera coupled with the output end of the third driving mechanism through the support frame can move close to or away from the positioning device. This design allows the camera to detect the liquid crystal display glass from multiple angles and distances, improving the comprehensiveness and accuracy of the detection. The second driving mechanism and the third driving mechanism allow the detection device to flexibly adjust the position and angle to adapt to liquid crystal display glasses of different sizes and shapes, enhancing the adaptability of the inspection table.

[0010] The support frame is provided with a light supplement lamp. The light supplement lamp can provide auxiliary light in insufficient light conditions, ensuring that the camera can capture clear images in various lighting environments, thereby improving the accuracy of the inspection.

[0011] The number of light supplement lamps is two, and they are arranged on both sides of the camera. The two light supplement lamps provide light from both sides, which helps to achieve uniform illumination of the inspection area and avoid shadows and uneven lighting caused by single-sided light sources, thereby improving the clarity of the image and the accuracy of the detection.

[0012] Compared with the prior art, the utility model has the advantages of:

[0013] The workbench bottom is evenly distributed with several supporting legs, which can provide better support and stability, ensuring that the workbench will not be displaced or tilted during the inspection process due to the weight of the liquid crystal display glass or vibrations during operation. The suction cups are evenly distributed on the support plate, providing uniform pressure when adsorbing the liquid crystal display glass, while also accommodating the positioning of liquid crystal display glasses of different sizes and shapes, and ensuring the stability of the glass during the inspection process. The first driving mechanism can drive the support plate to move closer to or away from the detection device, allowing the operator to adjust the distance between the glass and the detection device as needed to accommodate liquid crystal display glasses of different sizes. The automated positioning and moving device reduces the need for manual intervention, reducing the labor intensity of the operator, and also reduces the influence of human factors on the inspection results.
