[0008] The structure of the above two patent applications can basically complete the inductance sorting of the magnetic ring, but in the test use, it is all done manually. For each test, the metal cover needs to be removed from the metal column, and then the to-be-separated Put the magnetic ring on the annular insulating cover or the annular insulating cover, then close the metal cover, test and record, and finally take out the metal cover and the tested magnetic ring in the reverse order, etc. The operation steps are cumbersome, back and forth, and test The cycle is long and the efficiency is low. After a long test, the tester's hand will feel sore and swollen
In addition, manual testing and reading, the test error is large

The invention discloses an on-line automatic separation method for inductance of a small-inductance magnet ring. The method comprises steps of installing an on-line automatic separation device for the inductance of the small-inductance magnet ring, setting testing parameters, carrying out debugging, forming a standard magnetic ring sealed space, forming a closed magnetic access, separating inductance, resetting a metal cover and a test base and the like, wherein the on-line automatic separation device for the inductance of the small-inductance magnet ring comprises a multi-interval rotary disk with a plurality of through holes, the test base, a jacking device, an inductance tester, an automatic feeding device, a discharging device and an integration control panel in which a PLC (programmable logic controller) is arranged. A circular insulation block is arranged in each through hole of the multi-interval rotary disk, and the circular insulation block not only can bear the weight of the magnetic ring to be separated, but also serves as part of the standard magnetic ring sealed space. According to the method, in the whole inductance separation process, the automation degree is high; manual work is not required; the test speed is high; the efficiency is high; and the test data are accurate and reliable.
Description
technical field [0001] The invention relates to a magnetic ring inductance sorting method, in particular to a small inductance magnetic ring inductance online automatic sorting method. Background technique [0002] After the production of magnetic products is completed, it is necessary to test the magnetic products to check whether the magnetic products are qualified and provide data support for future process improvement. [0003] For the inductance test of toroidal cores, especially for magnetic devices with small inductance, such as nickel-zinc ferrite cores with small inductance, the unit of single-turn inductance is nH level, and the existing inductance tester basically cannot directly test it. [0004] In order to test its inductance and avoid instrument and test errors, the existing technology is to wind a multi-turn coil on the magnetic core to be tested, usually more than 50 turns, and use peripheral testing instruments to read the inductance value. [0005] Howeve...
