Metal Finishing: Workpiece positioners for finishing

A new generation of workpiece positioners for arc welding, thermal cutting and metal finishing applications

ABB Robotics has developed a new generation of workpiece positioners for arc welding, thermal cutting and metal finishing applications.

The positioners feature 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 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 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.

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.
