AI Technical Summary
Existing visual inspection equipment is difficult to achieve comprehensive and efficient inspection of complex workpieces such as electronic transformers. In particular, the transition area between the top surface and the side wall is prone to blind spots, and the flipping process can easily damage the workpiece. The inspection process is complex and inefficient.
Design a vision inspection device based on multi-station collaboration, integrating dual conveyor devices, dual rotating stages, multi-angle vision inspection units and automatic flipping mechanism, and coordinate their operation through a unified control device to achieve fully automated inspection of workpieces, including loading, flipping, multi-face inspection and sorting.
It enables comprehensive and efficient inspection of workpieces, ensuring no omissions, reducing labor costs, improving inspection efficiency, and meeting the high-standard quality inspection requirements of precision workpieces.
