Magnetic grippers are a type of end-of-arm tooling used in robotic automation for picking up and handling ferromagnetic objects. They work on the principle of magnetism, using a magnetic field to hold and release objects. Currently, electro-permanent magnetic grippers are popular. In this blog, we will introduce you EPM magnetic gripper working principle.
EPM Magnetic Gripper Working Principle
Electro permanent magnets consist of rare earth permanent magnet materials and an excitation coil. The permanent magnet material provides the magnetic field and the coil acts as a switch to control the direction of the magnetic field. In other words, it only uses electricity at the moment of magnetisation and demagnetisation, the magnetic field does not disappear even when the power is disconnected after magnetisation is complete. This is why an electro permanent magnet is both safe and energy efficient.
EPM magnetic grippers of HVR MAG has an electromagnetic force of up to 16 kg/cm². When the magnetic gripper is magnetised, it adheres firmly to the surface of the steel material. This adsorption type of gripping does not wear or deform the surface of the workpiece. And the magnetic gripper can hold steel parts of many shapes and sizes, as long as the weight of the workpiece is within the carrying capacity of the magnet.
The EPM magnetic gripper can be powered directly into the robot control system. This allows for better collaboration with the robot to complete the work task. No external components are required.
Applications of EPM magnetic gripper
Magnetic grippers are used in a variety of applications, including:
Material handling: Magnetic grippers are used to pick up and move ferromagnetic objects in manufacturing and assembly processes. They are commonly used in the automotive, aerospace, and electronics industries.
Sorting and packaging: Magnetic grippers are used to sort and package ferromagnetic objects such as screws, bolts, and nuts.
Benefits of EPM magnetic gripper
Magnetic grippers offer several benefits over other types of end-of-arm tooling, including:
Faster cycle times: Magnetic grippers can pick up and release objects quickly, which reduces cycle times and increases productivity.
Reduced maintenance: Magnetic grippers have no moving parts, which reduces the need for maintenance and repairs.
Improved safety: Magnetic grippers eliminate the need for manual handling of objects, which reduces the risk of injury to workers.
Versatility: Magnetic grippers can handle a wide range of ferromagnetic objects, making them ideal for a variety of applications.
