Description
Technical Field
[0001] The utility model relates to the technical field of AOI light sources, in particular to an AOI light source assembly. Background Art
[0002] Automatic Optical Inspection (AOI) technology, as a key tool for quality assurance in the electronics manufacturing industry, its core function is to capture images of the objects to be inspected through a high-resolution camera and rely on image processing software to analyze these images, so as to achieve the goals of defect identification, dimension measurement and assembly quality verification. Among these components, the light source assembly plays a crucial role.
[0003] In an AOI system, if the illumination brightness provided by the light source assembly is too high, it will cause overexposure of the image, which will hide important detail information or generate unnecessary reflections and glares; on the contrary, if the brightness is too low, it may cause underexposure of the image, making the details become blurred. Therefore, in order to achieve the best detection effect, the light source assembly in the AOI system usually needs to go through a long debugging process when applied to the production detection scenario to ensure precise control of the illumination brightness.
[0004] Therefore, aiming at the problem that the light source assembly in the above AOI system usually needs to go through a long debugging process when applied to the production detection scenario, which will affect the production efficiency, an AOI light source assembly can be designed to solve the above problem. Summary of the Utility Model
[0005] In order to overcome the problem that during the process of using the AOI system to detect products, in order to avoid the illumination brightness provided by the light source assembly being too high or too low, it is usually necessary to conduct a long-time debugging of the light source assembly in the AOI system during production detection, which will affect the production efficiency.

[0007] Preferably, the light emitted by the lamp beads will be more evenly and softly dispersed after passing through the soft light cloth, which is beneficial for the camera to obtain picture information. When the first synchronous pulley, synchronous belt, and second synchronous pulley are rotated by the motor, the light diffusing cover installed on the synchronous belt is displaced to change the thickness of the soft light cloth directly in front of the lamp beads, so as to change the intensity of the light after passing through the soft light cloth, thus completing the rapid adjustment of the illumination brightness.
