Vision Guidance System for Component Handling Robot

摘要

Vision systems offer innovative solutions to the manufacturing process. These systems are used in part positioning, robotic guidance and quality control to mention a few. The applied system for this study consists of a robotic arm that needs to get the position (x and y coordinates) and orientation of a component from a vision system. The aim of this study is to create a vision based system to detect and to pick and place predefined components within an assembly line system. Randomly placed components are fed into the system by a conveyor belt and moved into the inspection position. The inspection camera, mounted at a fixed position, and will acquire an image. The extracted features and data from the image are then processed using designed algorithms that pattern match, calculate x and y coordinates and orientation of the components. This data is then sent to a robotic arm which will then pick and replace the component. The results show what randomly placed components’ x and y coordinates and orientation can be determined that could eliminate the need of placement jigs.
