Case Study: Components

Fully automatic assembly line for the assembly and testing glow plugs

Production line consisting of pre-assembly module (2 Weiss rotary tables), press-in module (AGM12050), final assembly module (AGM16070), thermal testing system (linear unit), labeling and packaging module (Weiss rotary table). The components are interconnected by a workpiece carrier circulation system (2 sets: 1x production, 1x waiting position, automatic changeover). Setup is carried out exclusively by means of program specifications – for this purpose, more than 20 servo axes move automatically to other basic positions.
