Workpiece pick up (vertical, hanging): AGM unlocked – gripper opened
AGM deflected – gripper closed
AGM eccentrically locked via position memory – gripper closed
AGM centrically locked – gripper closed
AGM unlocked with spring or air cartridge – gripper closed
For comparison: AGM unlocked, without spring & air cartridge – gripper closed
AGM deflected with spring or air cartridge – gripper closed
Combined units AGM-XYZ and AGM-WZ
Workpiece pick up (vertical, hanging): AGM unlocked – gripper opened
The robot approaches the workpiece with an open gripper and the AGM (compensation unit) unlocked; the workpiece is positioned with an axis offset due to the tolerances or inaccuracies.
AGM deflected – gripper closed
The unlocked AGM can compensate for the existing axis offset between the gripper axis and the workpiece axis, ensuring that the workpiece can be gripped safely. The resulting eccentric position of the AGM can be locked/clamped by means of the integrated position memory.
AGM eccentrically locked via position memory – gripper closed
The robot picks up the workpiece and moves up.
AGM centrically locked – gripper closed
The position memory of the AGM is unlocked and the centric locking of the AGM is activated. This eliminates the previously existing axis offset, as the gripper and robot axis are now centered relative to each other.
AGM unlocked with spring or air cartridge – gripper closed
The robot moves to the drop-off position with the gripped workpiece and the AGM (compensation unit) is locked. There is an axis offset due to tolerances or inaccuracies. The AGM is unlocked for joining the workpiece. The unlocked AGM is held stable against gravity by the spring or air cartridges.
For comparison: AGM unlocked, without spring & air cartridge – gripper closed
Without a spring or air cartridge, the AGM is not stabilized against gravity and cannot compensate from the neutral middle position. It sags down due to its weight and gravity.
AGM deflected with spring or air cartridge – gripper closed
Thanks to the weight compensation, the AGM can compensate for the existing axis offset between the gripper axis and the workpiece axis from the neutral center position in the x- and y-directions.
Combined units AGM-XYZ and AGM-WZ
The AGM-XYZ and AGM-WZ compensation units from SCHUNK combine several compensation paths in one compact component.
Both units are pre-assembled and available with their own ID as a standard solution. Thanks to the compact design of the combined units, you benefit from significant savings in structural height and inherent weight compared to individual, stacked compensation units. This saves space, reduces the load on the robot and end effector, and ensures efficient implementation of your processes.
Application example
Application example
During automated loading and unloading of machine tools, compensation units can effectively compensate for tolerances.
