Handling thin iron sheets, flat or uneven iron sheets, perforated iron sheets, and small workpieces is a challenge that must be addressed in robotic automated handling.Through close cooperation with the Dutch Goudsmit Magnet company, leveragingthe technology of proper combination of vacuum and magnetic forces,our company provides customers with the followingautomated handling services for ferromagnetic objectsproject services.

Main handling targets:Thin iron sheets, flat or uneven iron sheets, perforated iron sheets, small workpieces, such aspressed or perforated steel parts and sheets,punched steel materials,metal mesh parts。

* Minimum thickness of sheets down to 0.5 mm,* Maximum lifting force up to 45 kg, viapneumatically controlled permanent magnets.

Suitable for transport and transfer applications:Automated production lines,Press transfer,Robot pick-and-place systems.

Robotic automated handlingChallenges to be solved for handling items such as thin iron sheets, flat or uneven iron sheets, perforated iron sheets, and small workpieces：

When using thin sheets (≤1mm), the "peeling effect" must be considered. This reduces the maximum separation force. In this case, it is best to create a structure with multiple smaller clamps (e.g., 40×40mm) using one or two large clamps.

When the fixture contacts paper, the paper may be damaged. If this is a concern, select the version with polyurethane protective caps (friction type).

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

Sometimes the sheet surface is uneven; in this case, vacuum grippers do not work. Magnetic grippers are then an ideal solution. The larger the contact surface area, the better, but magnetic grippers always work (on ferromagnetic steel) – even on circular shapes.

Another situation where vacuum does not work is with perforated sheets. This poses no problem for magnetic grippers. Ensure that you select a gripper sized larger than the holes and thoroughly test the selected solution.

For small workpieces, Goudsmit has very small grippers in its product range with low mounting height, which can provide additional holding strength for the workpiece. For example, select type HGR-RO-020.

For thin sheets (≤4mm) and oily sheets that stick together, robots sometimes pick up several sheets at once. Sheet separators prevent this. These are available in both permanent and pneumatically switchable versions.
