Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core processing, in particular to a fully automatic burr removal device for magnetic cores. Background Art

[0002] Nanocrystalline magnetic cores belong to a new generation of soft magnetic materials. They are popular because of their high initial magnetic permeability, high rectangular ratio, low core loss, and good high-temperature stability. Replacing traditional ferrite cores with nanocrystalline magnetic rings can reduce the size of switching power supplies and increase unit power. Nanocrystalline magnetic cores have the advantages of high magnetic permeability, low coercive force, high saturation magnetic induction intensity, low loss, and low magnetostriction coefficient. During the production process of the magnetic core, burrs will appear on its surface. In order to ensure the production quality of the magnetic core, the surface of the magnetic core is usually deburred.

[0003] When removing burrs from existing nanocrystalline magnetic cores, one hand usually holds the nanocrystalline magnetic core and rotates it slowly, while the other hand holds a grinding device to rotate and grind the burrs on the surface of the core. This method not only requires a lot of labor, but also leads to low work efficiency. In addition, when manually holding the grinding device to rotate and grind to remove burrs, the grinding force is mostly controlled by operating experience, which can easily cause scratches and damage to the surface of the core during grinding, thereby reducing the quality of core production.
