KUKA LBR grippers

The KUKA gripper portfolio offers you the right gripper as an end effector for any gripping task:

• KUKA sensitive LBR gripper for three different media flanges
• KUKA pneumatic long-stroke gripper for two different media flanges

With our LBR gripper portfolio, you can get to grips with anything. Their special design makes our grippers extremely flexible, precise and safe.

• Functions enabling human-robot collaboration
  There is no hazard whatever to the human operator due to the edge-free and rounded design. It is also possible to limit the gripping force to 140 newtons during collaboration instead of the maximum available force of 1000 newtons. Limitation for the pneumatic gripper is carried out using a sealed overpressure valve. For the sensitive gripper, fail-safe jaws are used. These are released in the case of a higher force, disabling the motion.
• Efficient and light
  All grippers are characterized by a compact design and low weight – making for excellent performance in terms of energy efficiency as well.
• Settable gripping force
  In the case of the pneumatic gripper, the gripping force can be infinitely adjusted up to the limit of 140 newtons on the ready-to-connect controller supplied. For the sensitive LBR gripper, the gripping force is specified via the controller.
• Fast integration
  Using the connecting cables supplied, the grippers can be integrated into the flexFELLOW or your system quickly and easily.
• Easy start-up
  Start working with the grippers right away - using the KUKA Sunrise.Gripper Toolbox: this assists you with the software setup and provides you with a simple programming interface for your applications.

The following components are included in the scope of supply:

• Compatible media flanges: electric or touch electric or inside electric
  
• Gripper mechanism with integrated controller
• Connecting cables for bus and energy (gripper to robot, robot to controller)
• Simple integration and control with KUKA sunrise.Gripper Toolbox
• Optional: safety jaws, flexible adaptive gripper fingers, KUKA flexFELLOW, KUKA LBR iiwa, Sunrise Cabinet including control cables for the robot
  
  

You will find additional components in the supplementary portfolio. Also find out about our flexFELLOW series and the possibilities that arise through the combination of a mobile unit and the LBR iiwa. 

The pneumatic long-stroke gripper from KUKA turns the LBR iiwa into the extended arm of the human operator. At the same time, the human is protected at the shared workplace. Two variants with a variable stroke and different gripping force and function are available:

The three-point gripping function enables the centric gripping of round workpieces.

• Combined gripping force of the three jaws: max. 700 newtons
• Gripper function: internal and external
• Stroke per jaw: 4 millimeters
• Closing time for total stroke: 58 milliseconds
• Gripping force safeguard: opening and closing
• Weight: 200 grams

The following components are included in the scope of supply for all three variants of the pneumatic LBR grippers from KUKA:

• Compatible media flanges:
  For long stroke: pneumatic IO, pneumatic touch
  For short stroke and centric gripper: pneumatic IO
  
• Gripper mechanism
• Proximity switches for detecting the states: gripper open, gripper closed, component gripped
• Mechanical, pneumatic and electrical interface
• Optional: KUKA flexFELLOW, KUKA LBR iiwa and Sunrise Cabinet
  
  

Additional options are available in our supplementary portfolio.

Our additively manufactured pneumatic LBR grippers are matched exactly to your needs: the jaws are perfectly tailored to the component and the manufacturing task by means of 3D printing. The integrated ball joint and the universally deployable flange adapter offer you additional flexibility. The 3D-printed LBR grippers are available in two variants:

The 3D-printed pneumatic two-jaw parallel gripper (RRMG3) is suitable for components up to a maximum of 500 grams

• Gripping force of both jaws: max. 120 newtons
• Gripper function: internal and external
• Stroke per jaw: approx. 2 millimeters
• Closing time for total stroke: 20 milliseconds
• Weight: approx. 500 grams

The 3D-printed pneumatic expansion gripper (RRMGI) is suitable for internal gripping of round components such as tubes or rings:

• Gripping force max. 300 newtons
• Gripper function: internal
• Weight: approx. 500 grams

The scope of supply for our 3D-printed pneumatic LBR grippers includes the following components:

• Compatible media flanges: pneumatic IO
• Flange adapter with ball joint
• Component-specific, additive manufacturing of the plastic jaws
• Gripper mechanism
• Proximity switches for detecting two states
• Mechanical, pneumatic and electrical interface
• Optional: KUKA flexFELLOW, KUKA LBR iiwa and Sunrise Cabinet
  
  

 Additional combination options and expansions are available in our supplementary portfolio.
