Small robot pallet exchange coupling
Schunk VERO-S NSR series slim robot couplings with optimized interfering contours have been setting benchmarks in highly efficient, robot-supported pallet exchange on machine tools in a weight class from 1kg to 1,000kg for many years. With the compact VERO-S NSR mikro 60 miniature coupling, Schunk now transfers rapid pallet exchange into the growing world of small robots. Due to the patented dual stroke system, the 60mm wide module has a weight of 150g and provides high maximum moments of up to 12Nm (Mx and Mz). It is suitable for reliable pallet handling of up to 5kg (max. 100mm x 100mm). Locking is done in a form-fit and self-retaining manner. For unlocking, a pneumatic system pressure of 5 bar is sufficient, and can also be carried out with non-lubricated air. The repeat accuracy amounts to 0.02mm.
The special hybrid design of the module ensures a high robustness at a low weight. All functional parts are made of hardened stainless steel, and the remaining parts are made of high-strength, hard anodized aluminum alloy. For supply of the clamping devices, the module can be equipped with Schunk standard media transfers for pneumatic pressure, electrics, or fluids. To ensure that the coupling is process-reliably functioning it is sealed against chips and coolant. Additionally, the cleaning function is integrated as standard for automated operation to ensure a chip-free flat work surface between pallet and robot coupling. On option, piston stroke and pallet presence can be monitored.
