Robotic Assembly Gripper Magnets

With magnetic grippers, you automatically pick up flat steel products or sheets up to 10 mm thick.
They are quick and easy to switch, and specially designed for transferring, placing or positioning using a robotic arm.

There are different types of robot end effectors. The most common are pneumatic grippers, because they are simple and low cost. Nowadays, a new player has entered the game and it is the electric gripper. This kind of gripper allows the user to control precisely the speed and position of the end effector. Suction cups are even more simple gripping devices since they use vacuum to lift flat objects. Then comes the magnetic gripper. This gripper is often forgotten in grippers lists, so we decided to expose you to its characteristics. Robotic Assembly Gripper Magnets

Magnetic grippers serve as end of arm tooling for sheets. They even hold perforated sheets effortlessly.

End of arm tooling of Robotic Assembly Gripper Magnets
Magnetic grippers are ideal when you want to pick up, place or position flat, steel products with a robot. The applications are very diverse, such as:

pick-and-place of steel parts
handling perforated sheets with a robot arm
unstacking workpieces from crates (bin picking)
positioning sheets in presses
stacking or unstacking hot baking tins
The high temperature gripper is suitable for this last example. For example, you can also use it to load and unload high-grade steel in a press; it is formed at high temperatures.

Magnetic end effector types

Electromagnets

Grippers using electromagnets are generally powered by DC power for handling material. This type of magnetic end effector is easy to control because the attraction can be turned off by shutting down the current. This can also help to remove the magnetism of the handled part.

Permanent Magnets

These kinds of end effectors do not need power to operate. They are always on. In order to separate the piece from the magnet, a push-off pin is included on the end effector. The permanent magnet offers an advantage when it comes to safety, since the gripper remains on even if a blackout occurs. Moreover, there is no possibility of generating sparks during production since no electric current is required.

Top 5 advantages

It only needs one surface to grab the object.
The grasping speed is fast.
It is flexible since it does not need different designs for different parts.
It can grip parts with holes which is not possible with vacuum grippers.
It requires minimal maintenance.

Top 5 disadvantages

When moved quickly, the part can slip out of the end effector.
Just a little oil on the surface can reduce the strength of the end effector.
Machining chips can stay on the gripper when unloading the piece.
Handled parts can stay magnetised.
It can only be used with ferromagnetic material.
