A permanent magnet gripper is a device used to hold and manipulate ferromagnetic objects. It is a type of gripper that uses a permanent magnet to hold steels. This technology is becoming increasingly popular in manufacturing and industrial applications due to its efficiency and versatility.
Working Principle: The permanent magnet gripper works by creating a magnetic field that attracts and holds onto ferromagnetic objects. The magnet is typically made of a rare earth material such as neodymium, which has a very strong magnetic field. When the magnet is brought close to a ferromagnetic object, the magnetic field causes the object to be magnetically attracted to the gripper. This attraction force can be adjusted by altering the distance between the magnet and the object.
Advantages of permanent magnet gripper
Versatility: Permanent magnet grippers can hold onto a wide range of ferromagnetic objects. Including irregularly shaped or curved objects that may not be easily held by mechanical clamps or suction cups.
Efficiency: Since there are no moving parts, permanent magnet grippers are very efficient and require minimal maintenance.
Safety: There is no risk of accidentally releasing the object if there is a power failure or mechanical failure.
Cost-effective: Permanent magnet grippers are not expensive and can be used in a wide range of applications.
Problems to be solved
The traditional permanent magnet gripper is limited by the control method. Which results in its magnetic strength not being adjustable and not intelligent enough. For example, pneumatic permanent magnets use cylinders to control the gripping and releasing action of the magnets. The magnetic force is not adjustable, so only a certain weight of steel can be gripped. As it may not be strong enough to grip large pieces of steel and may have residual magnetism when gripping small pieces, the versatility is not ideal.
But now we have the electropermanent magnet gripper, which solves these problems. The magnetic field of the electro-permanent magnet also comes from the permanent magnet material inside, but it uses an electric current to switch the direction of the field. So not only is it as safe and energy efficient as a permanent magnet gripper, but it can also adjust the magnetic strength to suit more sizes and weights of steel parts.
