Glüpker Blechtechnologie welds components for commercial vehicles with a two-station robot system by CLOOS. The two QIROX welding robots are mounted overhead on a C-shaped frame. Both robots are equipped with a seventh axis. The large range simplifies and accelerates the welding of the complex workpieces. The system also includes a 2-station workpiece positioner with vertical change and vertical rotation with counter bearing. The workpiece can be turned into the optimum processing position by a horizontal turning axis. The counter bearing stabilises even long workpieces during welding. The station change is made by a vertical rotation. Due to the two-station design, robot welding in one station and loading of the components in the other station is simultaneously possible.
