With the Foreign Object Detection System (FOS), Sick presents a system solution for minimizing process errors in the assembly of high-voltage batteries. When installing the battery into the body, the FOS uses laser triangulation to precisely check the battery surface for the presence of foreign bodies. It consists of a scalable system head with 3D cameras, a laser sensor to trigger the measurement processes and a sensor integration machine to record, evaluate and archive the measurement data. Mounted above the field of view, which is up to 2,400mm wide, the cameras scan the surface at speeds of up to 350mm/s. Foreign bodies of any shape, color and gloss properties can be reliably identified starting from a size of 4x4x3mm – even on complex surfaces with difficult structures and textures.
