In recent years, with the increasing popularity of wireless charging, wireless charging technology has developed at an alarming rate. The nanocrystalline has higher magnetic conductivity and saturation magnetic induction intensity, is a more ideal magnetic conductivity and electromagnetic shielding material, and is an important raw material in the wireless charging technology. However, the nanocrystals have low resistivity and high loss, and the charging efficiency of the material is reduced in the charging process, so that the nanocrystals need to be further processed; a magnetic fragmentation process is usually introduced to divide the nanocrystals into small units, thereby reducing the loss during the charging process and improving the efficiency.

In order to prevent the bad material from flowing to the downstream station to cause more scrap, the multi-layer composite station is usually led into a detection station, parameters such as magnetic resistance, inductance value and magnetic permeability of the nanocrystalline strip are detected through an LCR (inductance, capacitance and resistance) tester, and the performance of the nanocrystalline strip is judged through the parameters. The LCR tester consists of an induction coil and a host, and the fluctuation of the distance between the induction coil and a detection material has great influence on the measured value, so that the measurement coil and the detection material are required to keep a stable distance.

In the prior art, the movement of a nanocrystalline strip is stopped, a coil and the nanocrystalline strip are compressed by using an air cylinder and then measured, so that the stability of the distance between the coil and the nanocrystalline strip is ensured.
