goudsmit electromagnetic gripper for robot end-of-arm tooling

Product Information
goudsmit electromagnetic gripper for robot end-of-arm tooling

Goudsmit recently improved electromagnetic grippers are used for automatic picking, placing, or positioning steel or other ferromagnetic objects.


Examples include:

Removing metal sheets from presses

Taking products out of boxes (box picking)

Assembling steel parts

Handling stamped steel parts, blanks, and perforated steel sheets in robotic applications

The ultra-light magnetic gripper is equipped with robust neodymium magnets, making it very safe. It can be used as a gripper on robot arms. The actuating magnet can be opened and closed via compressed air and features a threaded hole interface for connection to the robotic arm, with an option to combine it with spring plungers.

Goudsmit robot end-of-arm tooling

This makes the magnetic gripper an effective alternative to traditional robot grippers, known as "robot end-of-arm tooling." The system is particularly suitable for lifting and transporting thin steel sheets one by one. The rubber pads at the end ensure that the workpiece does not slip during vertical picking and prevent damage to the workpiece. This easy-to-install system has been adopted by many large automotive manufacturers and the sheet metal industry.


Goudsmit vacuum technology

Using magnetic grippers on robot arms replaces traditional vacuum technology. A disadvantage of vacuum grippers is their susceptibility to failure and wear. Vacuum suction cups also require precise placement, as they will fail to hold if even partially positioned over holes in the metal sheet. Electromagnets used by other manufacturers are not a good solution to this problem because they are heavy and reduce lifting capacity. Magnetic grippers with permanent magnets are much lighter. Moreover, this gripper is less prone to wear and has a longer service life than vacuum grippers.

Points to note when using goudsmit electromagnetic grippers:

When using thin sheets (≤1 mm), the "peeling effect" must be considered. This reduces the maximum separation force. In such cases, it is better to design a structure with multiple smaller grippers rather than one or two large grippers (e.g., 40 x 40 mm).

When the grip paper gripper contacts the paper, the paper may be damaged. If issues arise, select a model with a polyurethane protective cover (friction type).

When using oiled paper or operating the robotic arm with high acceleration, the paper may shift. This can also be prevented by using polyurethane friction pads.

Sometimes, the surface of a sheet is uneven, so vacuum does not work. In this case, magnetic grippers are an ideal solution. The larger the contact surface area, the better, but magnetic grippers always work on ferromagnetic steel. Therefore, they also work on circular shapes.

When there are holes in the paper, vacuum will not work. Use magnetic grippers. In this case, select a gripper with a size larger than the hole dimensions, and thoroughly test the selected solution.

For small workpieces, Gudsmidt offers very small grippers. They have a low overall height and provide additional strength to hold the workpiece securely in place. For example, select type HGR-RO-020.

For thin sheets stuck together (≤4mm) and oily sheets, the robot sometimes picks up multiple sheets. Sheet separators prevent this. They are available in fixed and pneumatic versions.
