Magnetgreifer

Magnetgreifer, also known as magnetic grippers, are devices used in automation and robotics to pick up and manipulate ferromagnetic objects. They utilize electromagnets or permanent magnets to create a magnetic field that attracts and holds the workpiece. The strength of the magnetic force can typically be adjusted, especially in electromagnets, allowing for the handling of objects of varying weights and sizes.

These grippers are commonly employed in industries such as automotive manufacturing, metal fabrication, and logistics for tasks like lifting, placing, and sorting metal parts. Their advantages include the ability to handle delicate or irregularly shaped objects without direct contact, reducing the risk of damage. They can also operate in harsh environments where other gripping methods might fail.

The operation of an electromagnet-based magnetgreifer involves energizing a coil to generate a magnetic field, which is then deactivated to release the object. Permanent magnet versions often use a mechanical system to move magnets in and out of position, effectively turning the magnetic attraction on and off. Safety features, such as residual magnetism control and holding force monitoring, are important considerations in their design and application.
