Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an automotive lighting EOL testing machine. Background Technology

[0002] As people's living standards improve, cars have gradually become a common household item, bringing much convenience to people's travel. As the "eyes" of a car, headlights not only enhance the overall appearance of the vehicle but also provide a safety guarantee for drivers, especially at night or in rainy or snowy weather. Therefore, headlight testing is a particularly important process in automobile manufacturing.

[0003] Inspection of vehicle lights typically involves checking whether they illuminate, whether their brightness meets standards, whether any internal parts are missing, and whether the colors of the parts are accurate. Current inspection methods generally rely on manual monitoring, where inspectors visually inspect whether the lights illuminate smoothly, whether the brightness is sufficient, and whether any internal parts are missing or improperly installed. This traditional method is not only inefficient, but also easily leads to eye fatigue for inspectors after a period of inspection, potentially causing damage to their eyes. Furthermore, modern vehicle lights often have very complex internal structures, making it impossible to guarantee the accuracy of manual visual inspection, which could ultimately lead to serious consequences.

[0004] With the continuous development of technology, automated equipment has become the mainstay of production. Maximizing the use of machinery to complete vehicle headlight testing and reducing worker workload has always been a goal. Therefore, it is necessary to develop an automated vehicle headlight testing device that directly tests various indicators of vehicle headlights. This not only significantly improves testing efficiency but, more importantly, ensures accuracy and precision, eliminating any concerns. To this end, we propose a vehicle headlight EOL testing machine. Utility Model Content
