When the camera light source module 100 is used for detection later, the intersection of the infrared laser light path of the infrared laser component and the CCD light path of the camera light source module is the detection position of the CCD, and the object to be detected can be placed at this position. Through precise adjustment and alignment, it can be quickly ensured that the CCD camera can perform visual inspection at the ideal position in subsequent use, thereby improving the accuracy and reliability of detection.
