ABB Robotics Introduces a New Generation of Workpiece Positioners for Arc Welding, Thermal Cutting and Metal Finishing Applications

Nine new and improved models feature increased load capacities, greater accuracy, shorter cycle times and simplified programming

AUBURN HILLS, Mich. – ABB has released a new generation of workpiece positioners for robotic applications with improved load capacities and best-in-class motion control. The full range consists of nine models with load capacities ranging from 250 kg up to 5,000 kg. For the two most popular positioners, the IRBP K and the IRBP R the load capacities have been increased to 1,000 kg. These reliable, robust positioners are designed for manipulating workpieces during applications such as arc welding, thermal cutting, deburring and other metal finishing applications.

Employing the same drive systems and software as the ABB robots, the positioners are very easy to use and integrate, and have clear, simple instructions for programming. The axes of each positioner are fully coordinated with the robot during programming and operation. As the positioners operate, the robot system automatically optimizes speed and performance by taking advantage of maximum acceleration.

Shorter cycle times
The new range of workpiece positioners allows cycle time to be kept to a minimum with dynamic modeling software. The dynamic model automatically compensates for the effects of gravity, inertia and friction. The built-in Load Identification function (Load ID) calculates both the center of gravity and the inertia of the workpiece and fixture. These calculations ensure fast movements with rapid acceleration, re-orientation and accuracy when following programmed paths. This results in shorter cycle times, increased productivity and consistent high quality of finished parts.

Service-friendly
ABB workpiece positioners can also be supplied with all necessary safety equipment - and with a modular design and just a few robust moving parts, these service-friendly positioners require very little maintenance.

“We've designed this new generation of welding positioners as a true extension of the robot to fully optimize welding processes,” said Joe Campbell, vice president of the ABB Robot Products Group in the United States.  “We were happy to respond to key customers and systems integrators who recommended we increased positioner load capacities to expand the range of fabricated products ABB robots can weld.”
