IGM ROBOTERSYSTEME AG

More than 40 years experience in the development of welding robots and planning of production plants appear in a extensive range of system modules. The main module is the igm robot series RTE 400. Benefits, typical for igm robots: Outstanding programming techniques with both the K6 programming teach pendant and the offline teaching system. Large work zone and perfect welding access to seam positions due to an optimal axes geometry and mounting of the welding torch in the wrist axis, implemented as a hollow shaft. All cables are inside the robot arms using hollow shafts. The particular features of the RTE 400 modular robot system are the extremely slim robotic arms, optimized for weight and rigidity. For axes 2 and 4 there are available different lengths, the right range of movement can be selected for any application. The highly dynamic, maintenance-free AC servo motors and outstanding characteristics of the joint construction of rigid cast aluminium guarantee a high rotational...

Concept of RCE control system The control system is a fully digital controlled system. This means there are only digital signal processors (DSP) involved in the entire control system and not any analogue electronic component. All the components of the control system (such as control cabinet, welding power source, each axis and the teach pendant) are linked by a digital bus system. A full digital robot control system brings the following advantages: No influence by any environmental disturbance like inductive fields of welding cables Quickest response time by fastest bus connection > smooth motion of robot Absolute reproducibility of welding result > highest consistency in welding quality Easy diagnosis possibilities of the entire robot control system > less skills and no special instruments for diagnosis are necessary By using modular drive technology and standard PC components a high reliability is guaranteed and the ability to remain constantly at the cutting edge of...

Operational availability of the robot installation for production is increased by using an off-line system for generating robot programs. While saving time, programs may be prepared more conveniently in an office environment and simulation test runs (accessibility, computation of cycle time) may be performed. Collisions of the robot with the workpiece or fixtures may be detected at an early stage. Offline programming - Online working Simple robot programming is available through the self developed PC-based off-line programming system, using the original software of the robot control system and the teach pendant K6. Offline programming involves work piece oriented programming in 3D mode using a PC and simulation software. The workpiece is first imported into the programming system as 3D-CAD geometry, then the movements of the robot are determined. For path generation and definition of the processing parameters, a number of automatic functions as well as data bases stored in the...

igm gas nozzle searching - Tactile sensor for position detection This tactile sensor is used to determine the workpiece position or its components and individual parts by gauging the surface of the workpiece. In each case, the successional part of the program is shifted according to determined deviations. Sensor shifting may be applied for correction of an arbitrary amount of individual points, entire sections of a welding program or entire programs. Combination with arc seam sensing is feasible. The control system supports shifting, rotating, and tilting of a program, depending on position change. The gas nozzle itself is used as a sensor. This makes it possible - even on complicated workpieces and in confined spaces - to perform the required search steps on the reference surfaces of the workpiece, by which the position of the weld seams is determined. As soon as the gas nozzle gets into contact with the work piece, it is discharged and the robot stops immediately. This...

igm robot periphery The robot is mounted on the robot periphery in an upright or suspended position. The external axes of the track systems are fully integrated in the control system as NC axes, significantly extending the working area of the robot. A variety of different rotating and linear units are available, either as single axes or combined with up to three positioning units. It is also possible that several robots share a track axis. The positioning range of a longitudinal axis is up to 100 m and more. igm workpiece periphery The workpiece periphery holds, positions, and moves workpieces. The external axes are fully integrated in the control systems as NC axes and, in addition, feature manual control functionality. External axes may be included in workpiece manipulation during execution of welding steps. Using the teach pendant, they are programmed together with the robot axes. A variety of different rotary modules is available, as a single axis or combined with up to three...

The igm compact systems are optimized for arc welding applications in all mechanical aspects as well as the control hardware and software. In this combination of work piece and robot peripherals, the entire system is kept compact, since the robot changes workstations simply by pivoting the rotary arm or - in other configurations - the work station cahnes is performed by a rotary table. The drive is axis-controlled and provided by an AC servo motor with a special gear box and a built-in digital encoder. The turning fixture is perfect for use as an external robot axis. Work piece movement is completely integrated in the robot control system and permits synchronized movement of the work piece during the welding sequence. The programming takes place simple via the teach pendant K6. All necessary control components for manual and automatic operation are integrated in the system. Examples for igm compact systems and complete welding cells igm compact systems, type RSX 501, 502, 1001,...

The welding torches are designed for use on robots for high-performance welding under harsh conditions. The slim design, together with the swan’s neck shape, permits the best accessibility even in narrow parts of the work piece. All welding torches provided as standard for igm robots have a particularly stable design with intensive water cooling and a quick-release coupling. They are also configured for pneumatic torch cleaning with compressed air at least 7 bar and for the use of the gas nozzle as a tactile sensor for program shifts. The arrangement of the contact tube in connection with the torch curvature ensures the forced contact of the welding wire. This ensures a uniform and constant current transition to the wire electrode under all conditions and wear conditions. Direct water cooling of the gas nozzle reduces the adhesion of weld spatter. The cooling water is routed through its own channels in the torch body up to the contact pipe, and from there through the nozzle stock...
