As the experts for clamping technology and gripping systems maintain, the module adds the necessary flexibility to the end-effector during bin picking, for automated loading and unloading of machine tools, and for handling and assembly applications with inaccuracies in the positions of components. As is further explained, grippers and other actuators connected to the robot via the unit can effectively 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 lies between 0° and plus/minus 13°, and between 0° and +/- plus/minus 19° around the Z-axis (rotation). An optimum deflecting torque is achieved by individually adjusting the centering force with compressed air. If the unit is switched into its rigid position, the locking reportedly ensures a high centering accuracy of plus/minus 0.09 mm using a proven ball mechanism, and therefore ensures maximum process reliability in subsequent operations. A monitoring of the locking is possible by the use of inductive proximity switches.
Combined rotational and angular compensation for end-effectors
As the world's first angle compensation unit for robots, the Schunk AGE-W combines rotational and angular compensation around all three axes. It thus enables a fast and precise handling of parts whose position is not exactly defined.
