Best-Fit Installation in Car Body Construction with 2D/3D Profile Sensors

In the body construction for passenger cars, attachments such as tailgates, bonnets, roofs or side doors must be placed and installed in the bodywork fully automatically by robots. This so-called “best-fit” process in assembly lines is supported by 2D/3D profile sensors in order to achieve uniform circumferential gap dimensions between these parts and the body. Six to eight profile sensors per robot measure the position of the parts relative to each other using laser triangulation. Finally, the optimal installation position and thus the even distribution of the gap dimensions are calculated using software.
