In the customer's automated assembly line, robots replace manual labour to perform loading and assembly operations. At the camshaft tile loading station, because the workpiece slides slightly in the frame during transport, resulting in uncertainty about the incoming material position, the customer introduces a 3D vision system to locate the spatial position of the workpiece and adjust the robot's end-axis position for accurate gripping. At the same time, multiple workpieces can be identified within the effective field of view, which is convenient for customised fixtures to grip multiple workpieces simultaneously to meet the requirements of subsequent station assembly.
