[0002] An LED module inspection machine is an automated device specifically designed to inspect outdoor LED display modules. It typically integrates machine vision technology to detect LED module brightness, color, and defects such as dead lights, dimmed lights, and stringy lights. It also ensures that the display module's brightness and color uniformity meet standards. It also checks for screws that are missing, off-center, white, loose, or floating.

[0003] An LED module inspection machine is needed in the LED module inspection process. In the existing technology, LED module inspection is completed manually. Workers observe with the naked eye and then rely on experience to judge whether there is a problem. This method of manual naked eye observation and experience judgment can meet certain production needs, but it also has major defects. Due to the need to meet the inspection needs of LED modules of different sizes and types and ensure a high-efficiency inspection process at the same time, manual operation efficiency is low, labor intensity is high, labor costs are high, long-term observation can easily cause eye fatigue, and safety and health risks are great. It is easy to miss detections, misdetections, and false detections, and the accuracy is low. It cannot effectively meet the needs of mass production. Therefore, an outdoor LED module inspection machine is proposed to solve the above problems. Utility Model Content
