AGM-XY

AGM-XY

Compensation unit
Modular compensation unit with XY-compensation for the compensation of inaccuracies and tolerances. As part of the AGM product family, the AGM-XY can be flexibly combined with the AGM-Z and therefore always offers the right compensation behavior for a wide range of applications.

AGM-XY 補正ユニットは、X軸とY軸の補正を行います。特許取得済みのユニプラナーガイド配置と、頑丈で滑らかな走行のリニアローラーガイドにより、最小の全高で高荷重と高トルクを処理できます。例えば、このユニットは内蔵された空式式ロック機構とポジションメモリ機能を使用して、コンポーネントの目標位置合わせのために、中心位置でも偏心位置でもロックすることができます。統合されたストローク調整機構により、X軸およびY軸の補正移動量を個別に調整でき、必要に応じて完全にロックすることも可能です。

ワークピックアップ (垂直、吊り下げ): AGMロック解除 – グリッパー開

ロボットはグリッパーを開いた状態で、またAGM（補正ユニット）のロックを解除した状態でワークに接近します。ワークは、公差や不正確さにより、軸がオフセットした状態で位置決めされています。

AGM 偏向 – グリッパー閉

ロック解除されたAGMは、グリッパー軸とワーク軸間の既存の軸オフセットを補正することができ、これによってワークの安全な把持を保証します。その際生じたAGMの偏心位置は、内蔵のポジションメモリによってロック/クランプすることができます。

ポジションメモリによりAGMを偏心ロック – グリッパー閉

ロボットはワークを拾い上げ、上に移動します。

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.

Select the cartridge suitable for your application to keep the AGM in the neutral center position during horizontal and inclined compensating processes, and to enable reliable compensating. Talk to us, we will be happy to advise you.

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.

Note: The spring cartridge works exclusively via the spring force and can be adjusted manually. Depending on the size, different force ranges are available to optimally adapt the weight compensation to the specific requirements of the application. The air cartridge combines spring force with the option of supplying additional compressed air. This allows the forces to be adjusted during the process via the compressed air and flexibly adapted to the respective requirements.

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.

  • AGM-XYZ: Combines the compensation paths in the xy- and z-axes

  • AGM-WZ: Combines angular compensation and compensation in the z-axis

    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.
