Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp detection, and more specifically to a visual detection mechanism of vehicle lamp detection equipment. Background Art

[0002] Headlights, as the "eyes" of a car, not only enhance the image of the entire vehicle, but also provide a safety guarantee for the driver when driving at night or in rainy and snowy weather. Therefore, in the manufacturing process of a car, the inspection of headlights is a particularly important process. Generally, visual inspection agencies are used to inspect whether the lights are on, whether the brightness of the headlights meets the standards, whether there are any missing parts inside the headlights, and whether the color of the parts is accurate.

[0003] For example, a Chinese utility model patent with announcement number CN215811553U discloses a visual inspection mechanism for a vehicle lamp inspection device, including a detection mechanism body, a detection platform and a terminal. The detection platform is provided at the upper end of the detection mechanism body, and a guide rail, a telescopic column and a plug rod are provided on the upper surface of the detection platform. The vehicle lamp to be tested is provided at the upper end of the plug rod, and a vehicle lamp reflection area is provided on one side of the guide rail.

[0004] Based on the above, the inventors found that: during detection, the detection mechanism in the comparative document drives the reflective component to move through the guide rail. Since the reflective component is large in size and needs to move back and forth, the requirements for movement stability are high, and the existing detection mechanism lacks an effective supporting and stabilizing structure. Therefore, in view of this, the existing structure is studied and improved to provide a visual detection mechanism for vehicle light detection equipment, in order to achieve a more practical purpose.
