Device for testing magnetic flux of magnetic component

Abstract

The invention discloses a device for testing magnetic flux of magnetic component, comprising support frame, object table which is fixed on the support frame, electronic scales and iron block which are located below the object table. The object table is made up by non-magnetic conduction materials, the upper surface and lower surface of object table are level, iron block is placed on electronic scales, the upper surface and lower surface of iron block are level, there is a space between upper surface of iron block and lower surface of object table; the advantage of device is that the magnetic flux of magnetic unit is shown by the readings of electronic scales, operation personnel just needs to place the magnetic unit to be tested on object table. Operation personnel can judge if the magnetic flux of magnetic unit is qualified or disqualified according to the readings of electronic scales, the operation is simple. The qualification or disqualification of magnetic flux of magnetic unit is shown according to the readings of electronic scales. The judgment cannot be influenced by the external factors and the test accuracy is high.

Description

technical field [0001] The invention relates to a detection device, in particular to a device for detecting the magnetic flux of a magnetic element. Background technique [0002] With the development of science and technology, more and more magnetic components are applied to various fields. In order to ensure the quality of the magnetic components, after the production of the magnetic components is completed, it is necessary to check whether various important parameters (such as magnetic flux) are within the qualified range. [0003] Existing devices for measuring magnetic flux generally include a flux coil (Helmholtz coil) and a fluxmeter, and the flux coil and the fluxmeter are connected. When testing the magnetic flux, turn on the fluxmeter, put the magnetic element into the flux coil first, then take the magnetic element out of the flux coil and keep it away from the flux coil for a certain distance, the fluxmeter will test the magnetic element magnetic flux and output...

AI Technical Summary

Problems solved by technology

However, the existing equipment for measuring magnetic flux has the following problems: first, the magnetic element needs to be placed in the magnetic flux coil and then away from the magnetic flux coil to complete a detection process, and the operation is more complicated; second, the magnetic element is theoretically far away from the magnetic flux coil The farther the distance is, the higher the accuracy of the test data of the magnetic flux tested by the fluxmeter is, but in actual production, in order to ensure the efficiency of the test, the distance between the magnetic element and the flux coil is determined, and this distance will not be too large. This magnetic component will interfere with the test of the fluxmeter, so that the accuracy of the test data of the magnetic flux is not high
