Robot unloading and testing for vl joints
Addition of a test station to an assembly line.
In this project, WEBER deploys two 6-axis robots (cobots) within the test cell: the first 6-axis robot positions the camera, lighting unit, and a laser triangulation system to carry out various inspection tests; the station is motor-driven and rotatable, and equipped with an incremental encoder. The second 6-axis robot, fitted with an automatic gripper-changing system, removes the tested component after a successful pass inspection and places it into a Kolox box. The robot also handles placing the intermediate trays into the Kolox box.
Faulty joints are returned by the handling system to the deposit conveyor and routed to the reject station. To enable this, WEBER retrofitted the deposit conveyor and workpiece carriers with a read/write system.
