Magnetic permeability testing equipment and testing method thereof

Abstract

The present invention provides a magnetic permeability testing device and a testing method thereof, and relates to the technical field of devices or instruments for measuring magnetic variables. The magnetic permeability testing device comprises a main frame body, a lifting mechanism, an upper mold assembly, a lower mold assembly and a weak magnetometer; the lifting mechanism is installed on the main frame body; the upper mold assembly is connected to the lifting mechanism, and the lifting mechanism can drive the upper mold assembly to move up and down in the direction close to or away from the lower mold assembly; the lower mold assembly comprises a loading plate and a rotating drive assembly for driving the loading plate to rotate, and the rotating drive assembly is installed on the main frame body; the loading plate is used to position and place a single product with multiple steel sheets; the weak magnetometer is installed on the upper mold assembly; the loading plate drives multiple steel sheets of a single product to rotate, and multiple steel sheets can be respectively set corresponding to the probe of the weak magnetometer. The technical problems existing in the prior art that a single fixture corresponds to a single steel sheet position, cannot be applied to products with multiple steel sheets on a single FPC, and have low testing efficiency are solved.
