The AGM-XY compensation unit offers compensation in the x- and y-axis. The patented uniplanar guide arrangement with heavy-duty and smooth-running linear roller guides enables the handling of high loads and torques with minimum overall height. For example, the unit can be locked both centrically and eccentrically for the targeted alignment of components using the integrated pneumatic locking mechanism and position memory. With the integrated stroke adjustment, the compensation travel in the x- and y-axis can be individually adjusted and, if necessary, completely locked.

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
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.
