Releasing a Part with the Robotiq E-Pick Gripper

Context

In some applications, you may need to release a part quickly, or the part being handled by the E-Pick might be particularly light. In these cases, a blowoff might seem like the ideal solution.

However, the E-Pick does not support blowoff functionality.

Why Blowoff Isn’t Available on E-Pick

The E-Pick gripper uses an integrated vacuum generator and does not have the ability to reverse airflow (blowoff). This design prioritizes simplicity and efficiency, but it also means that releasing parts must be managed differently.

Recommended Solutions

To ensure smooth release of the part, try one of the following:

• Slow down the robot’s movement when it is detaching from the part. This gives time for the air pressure to equalize, allowing the vacuum to naturally break and the part to be released. This technique is especially effective for lightweight or delicate objects.

• Reduce the maximum grip (vacuum) pressure used to pick the object. A lower vacuum setpoint breaks more easily once the cup lifts off, which helps when slowing the robot down is not enough on its own.

• If the application needs a fast, active release, consider the Air-Pick, which supports active blowoff.

Conclusion

Although the E-Pick cannot perform blowoff, reliable part release is still achievable by slowing the robot’s release motion or lowering the grip pressure. For applications that require a fast, active release, the Air-Pick is the better fit.
