Presence Check for Screws and Nuts via Laser Distance Sensors Triangulation

In the automotive industry, metal or plastic components are often fixed to larger body parts with screws and nuts. To check whether nuts and screws are present and in the correct position after the robot-controlled screwing process, a laser distance sensor triangulation is installed above the component. With its fine light spot, it checks whether the small nuts and screws have been correctly positioned and screwed in. Its high accuracy means that even the smallest, darkest and most reflective objects can be reliably detected against any background.
