Combined rotational and angular compensation on the end-effector

For automated loading and unloading of machine tools

As the world's first angular compensation unit for robots, the SCHUNK AGE-W combines rotational and angular compensation around all three axes. In doing so, parts without a precisely defined position can be handled quickly and precisely. The module provides the necessary flexibility to the end-effector during bin picking, for automated loading and unloading of machine tools, as well as for handling and assembly applications with inaccuracies in the components' positions. Grippers and other actuators connected to the robot via the SCHUNK AGE-W, can excellently adjust their position to the respective workpiece position without having to record the process in detail via a vision system and without having to precisely calculate the gripping strategy every time. This saves time in programming and during operation. Around the direction of the X and Y axes, compensation is between 0° and +/- 13°, and between 0° and +/- 19° around the Z axis (rotation).

Optimum deflecting torques are achieved by individually adjusting the centering force with compressed air. If the unit is switched into its rigid position, the locking ensures a high centering accuracy of +/- 0.09 mm using the proven ball mechanism and therefore ensures maximum process reliability in subsequent operations. Monitoring of the locking is possible by using inductive proximity switches. The anodized aluminium housing and hardened stainless steel compensation elements ensure a long service life and minimum maintenance. The unit can be connected to various robots without using adapter plates since the flange pattern is standardized in accordance with DIN EN ISO 9409-1-125. The maximum horizontal handling weight is 22.7 kg.
