With the Cobot Turn 100 A rotary-tilt table, Lorch Schweißtechnik is launching an additional component for the Lorch Cobot Welding Package that makes welding production with the collaborative robot even more efficient. The two-axis manipulator can be easily integrated into the production process.
The trend towards fully and partially automated welding continues to grow. With the “Cobot Welding Package”, Lorch Schweißtechnik already offers a solution for small and medium-sized companies to easily automate welding processes and to significantly increase the quality through the exact programming and reproducibility of the welds. In combination with the new manipulator, more demanding workpieces can now be welded in top quality in a continuous program sequence.
The Cobot Turn 100 A can be mounted on any welding workstation, either on top of the table or on the side of the table cheek. It can accommodate components with a radius of up to 750 millimetres, a height of up to 550 millimetres and a mass of up to 100 kilograms.
With a tilt angle of 0 to 90 degrees and an infinite rotation angle, it always enables the appropriate welding position in the tub position and thus the desired seam quality. The time-consuming turning and re-clamping of the workpiece by hand is no longer necessary – valuable working time is saved and the welder’s workload is significantly reduced.
Rotationally symmetrical parts automatically
The positioner can be programmed instantly and intuitively via the common control panel thanks to a simple upgrade of the Cobot operating software. The Lorch Motion software, which is fully integrated in a URCap, ensures that the programming of the cobot and the rotary tilting table are optimally coordinated.
Using Lorch Motion, the positioning of both axes is defined, the speed is configured and, if desired, a partially synchronous movement with the cobot is also specified. With the assistance system for the circumferential welding of rotationally symmetrical components, for example, only the radius and the desired welding speed need to be entered into the system, then the software also automatically calculates the optimum rotational speed of the positioner.
Virtual enclosure of the welding area
Lorch has paid particular attention to the safety concept. During production operation, a permanently installed laser scanner generates a virtual enclosure that monitors the work area. If the activated protective field (1.5 m distance to the work surface) is entered, the entire production process stops. Due to the fuse, the permitted travel speed of the cobot between the welding seams is higher and makes the welding process even faster.
Caren Dripke, Head of Robotics Development at Lorch: “The welding cobot from Lorch in combination with the new rotary-tilt table significantly increases welding performance once again. The optimum position can now be specified for each weld seam and the entire welding process can be carried out by the cobot alone. This not only leads to a higher welding quality. The welder is also relieved of time- and power-intensive reclamping processes – his net welding time increases and he can concentrate on other workpieces in parallel.” Added bonus: “Thanks to its ease of use, the solution can be quickly deployed in companies and offers a very fast return on investment due to its high efficiency.”
