Schunk’s Universal Compensating Unit Enables Intuitive Bin-Picking
Schunk’s AGE-U universal compensating unit enables reliable gripping without having to first detect the exact position and location of the gripping object. Its complex design combines angled, lateral and rotary compensation and applies sensor detection once deflection takes place.
When bin picking, ferromagnetic blanks can be picked up by a magnetic gripper without having to detect their exact position or orientation. All that is needed is an approximate localisation, using equipment such as a simple 2D scanner. In addition, the module can compensate for tolerances and position deviations in six axes during automated assembly.
The AGE-U has combined rotation and angular compensation, allowing the end effector to fully adapt to the undefined component position or to feed through insertion operations with gripped components. In the X and Y directions, the maximum possible compensation is ±2.7mm. In the Z direction, it is ±6.1mm. Laterally, the compensation around the X axis and Y axis is at up to ±3 deg, rotationally, it is at up to ±8 deg around the Z axis. While the return to the basic position is achieved both via springs and actively via compressed air, the flexibility of the unit can be adjusted individually by regulating the air pressure. At a pressure of 6bar, the unit is switched to a completely rigid mode, eliminating uncontrolled movements during the handling system process. Both the locked status as well as the deflection of the unit from the basic position can be monitored via inductive monitoring of the locking piston.
The compensation module is recommended for handling weights up to 5kg and can be connected to a wide range of industrial and lightweight robots quickly and easily using the standardised ISO-50 flange without adapter plate. The housing made of anodised aluminium and the functional components made of hardened steel ensure a long service life and reliable operation with minimal maintenance costs. The Schunk AGE-U is designed for one million compensation cycles.
