Laser-based vision system ensures accurate welding

摘要

Many of today's automotive components must be properly assembled into sub-components before they can be installed. Manufactured from multilayer plastics, these components often have complex geometries that make manual assembly difficult. Rather than perform these tasks manually, companies such as BF-Maschinen (Geretsried, Germany; bf-maschinen.de) manufacture systems to perform these tasks. To assemble gas tanks and fuel filler hoses, for example, the company has developed a system that automatically performs the task of welding the two plastic parts together. To perform this task, each individual part is heated, pressed together and then allowed to cool.
