The LED module inspection machines in the prior art place LED modules on the inspection platform, and the conveying mechanism conveys the modules to the bottom of the imaging system. The industrial camera captures the module image with the assistance of LED lighting, and the image processing unit analyzes the image and identifies defects. The control system determines whether the module is qualified according to preset standards, and finally presents the inspection results on the display interface. However, the existing inspection machines may only be able to adapt to LED modules of specific types or sizes, and are not flexible enough for diversified product lines, and may be sensitive to environmental conditions. For example, changes in temperature and humidity may affect the inspection accuracy and equipment stability, and cannot meet production needs. Therefore, an indoor LED module inspection machine is proposed to solve the above-mentioned problems. Summary of the invention
