[0002] Magnetic core is a key component used in electronic devices, mainly used in inductors, transformers and other electromagnetic components, which improves the efficiency and performance of these components by concentrating and guiding magnetic fields.

[0003] In the production and processing of magnetic cores, the size of the magnetic core needs to be sorted, because the size error of the magnetic core has a direct and important influence on the performance of the product. The change of the size of the magnetic core will directly affect the inductance of the winding. If the actual size of the magnetic core deviates from the design value, it will cause the inductance to deviate from the expected value, and thus affect the working frequency response and efficiency of the filter, transformer or choke coil.

Such technologies all use some existing instruments to detect the magnetic core, such as light sensor detectors or laser range finders, and are used in combination with assembly lines. Although the work efficiency is high, the cost is also high, and when small batch sorting operation is performed, the sorting device may not be suitable, so a magnetic core size sorting device needs to be proposed.
