Description

Technical Field

[0001] The utility model relates to detection equipment, in particular to a visual detection and testing tool. Background Art

[0002] Automated optical inspection (AOI) is a visual inspection technology widely used in the electronics manufacturing industry to improve product quality by effectively identifying defects during the manufacturing process. The technology combines advanced optics, cameras, and image processing capabilities to perform inspections, and can inspect a variety of surface features on workpieces, including the presence or absence of components, size, color, shape, alignment, and pattern.

[0003] Existing visual inspection equipment is usually installed on one side of the belt line through a bracket. The workpiece to be inspected is placed on the belt line, and the side of the workpiece to be inspected needs to be aligned with the belt line so that the image of that side can be acquired by the visual inspection equipment for inspection. If it is necessary to inspect multiple external surfaces of the workpiece, it is generally set on the other side of the belt line, and both sides of the workpiece are inspected at the same time. If more inspections are added, it is necessary to manually rotate the workpiece, adjust the position, put it on the belt line, and then transport it between two opposite visual inspection equipment by the belt line to inspect the surface that was not inspected in the previous process. Therefore, an improved technology is proposed, which can save equipment resources and test tooling for the process, thereby saving equipment costs and inspection time for the enterprise.
