Gripper testing and calibration with GripLAB

Your robot has caused a collision. You have succeeded in aligning the gripper so that the workpiece fits in the gripper without tension, but neither the pick-up position nor the set-down position, nor the machining points or paths in between are OK because the real workpiece no longer matches the tool data. Adjustment of the tool frame in 6D, including orientations, is required to achieve the exact form fit required on all sides of the gripper.

GripLAB provides you with a quick, automatic check and calibration of the tool frame so that your robot is up and running again in no time.

GripLAB benefits

High accuracy calibration system for 6D gripper or tool frame measurement

High accuracy calibration system for 6D gripper or tool frame measurement

GripLAB - The 6D expert for automated control and rapid calibration of grippers and components

GripLab enables complete 6D measurement of a gripper or component, including orientation, in less than 60 seconds. The system can take control measurements during operation, detect any positional deviation and correct it automatically. Or to get cells up and running again in the shortest possible time after a collision. The system captures the entire possible error chain from the robot flange to the component in one step, thereby increasing the process reliability and availability of handling cells.

Hardware

GripLAB is a compact measuring system with precise laser measurement technology.

It is mounted in the robot cell by means of an adapter plate that is included in the scope of delivery. Connection to the robot controller is via either an RS232 or Ethernet interface. Optional connection via fieldbus, ProfiNET, DeviceNet or EtherCat.

Process

How the GripLAB calibration process works

GripLAB measures a gripped component or the gripper of a handling application in less than a minute. If the control measurement exceeds a specified tolerance, the tool data can be corrected directly in the control. GripLAB can be used during ongoing operation. In this way, creeping deterioration of the gripping process can be detected and corrected at an early stage – before a collision occurs.

The calibration process is demonstrated in the adjacent video.

The individual process steps

Initial situation

The initial commissioning of GripLAB after installation in the robot cell involves a simple motion programme with nine measuring points.

Inspection

After a crash, the test shows that the gripper is misaligned. No additional software installation on the robot controller is required.

Measurement

Automatic measuring of the gripper is done by running the moving programme.

Calibration

Calibration of the gripped part. After automatic transfer of the corrected tool data, the gripping process is precise again.
