Video: The Gripper Also Grips Delicate Objects Non-destructively
The mechatronic gripper with the gripping force specification option receives this directly via the control or using a separate trigger device. The required gripping force can be set directly via the control via an analog value specification of 0 V to 10 V. This means that even very delicate components can be traded without destroying them.
Optionally, the required analog value can be specified via an intermediate device (trigger) and saved on the control card of the gripper. This becomes necessary if the user does not have a free analog output on the system, but would like to set a defined gripping force.
No unwanted change in gripping force possible
In addition, it is impossible to bring about uncontrolled changes in gripping force, as is for example prohibited by medical and pharmaceutical applications. An unwanted change in the gripping force caused manually by the worker is now excluded. With this function, the gripper fulfills the requirements for said applications necessary for validation.
The positions of the gripper jaws were previously recorded using the sensors optionally attached to the gripper. Since this always caused additional installation effort and adjustment work, Gimatic has now integrated high-resolution encoders into the mechatronic grippers. These directly record the positions of the jaws, so that there is no need to use sensors.
The GMP-compatible mechatronic gripper developed last year in cooperation with the IPA Stuttgart has a gripper cover that fulfills all the requirements to be considered a GMP. After the market launch in 2014, there was great interest in these gryphons. For example, a Japanese robot manufacturer is already selling it as a system solution, "Robot - Gripper". (jv)
