Problems solved by technology

However, the nanocrystalline strip after being crushed by the magnetic crushing roller will produce a small amount of debris particles and surface cracks, and the final nanocrystalline product is formed by compounding multi-layer nanocrystals. Dust particles will cause the surface of the finished product to bulge, and the bulge and internal cracks will bring greater safety hazards to the final wireless charging product
However, in the prior art, when testing nanocrystalline materials, it is usually necessary to keep the material still, and the efficiency is relatively low. Usually, in order not to affect the flow speed of the material and ensure the production efficiency, sampling testing is used for testing, and the conditions may not be met. of nanocrystalline materials are made into end products

Abstract

The invention provides a nanocrystalline material detection method and a terminal. The method comprises the following steps: collecting the movement speed of a to-be-detected nanocrystalline material; determining the shooting frequency of the nanocrystalline material to be detected according to the movement speed; sending the frequency to a detection camera, and obtaining a detection image collected by the detection camera according to the frequency; collecting a detection result according to the detection image; compared with the prior art, the device does not need to be specially stopped in the process of conveying the nanocrystalline material to enable the nanocrystalline material to be static for detection, so that the circulation of the nanocrystalline material between the working procedures is not greatly influenced, the detection efficiency of the nanocrystalline material is greatly improved, and conditions are provided for detecting all the nanocrystalline materials after the working procedures are finished.

Description

technical field [0001] The invention relates to the field of quality inspection, in particular to a nanocrystalline material inspection method and a terminal. Background technique [0002] Nanocrystalline materials are usually used as magnetic permeability and electromagnetic shielding materials in existing wireless charging because of their high magnetic permeability and high saturation magnetic induction. However, in order to avoid the disadvantages of low resistivity and high loss while utilizing the advantages of nanocrystalline materials, it is necessary to divide nanocrystals into small units to reduce losses during charging and improve charging efficiency. [0003] In the prior art, a magnetic crushing process is usually introduced to divide the nanocrystals into small units, and one of the operation methods is to crush the nanocrystalline ribbons through a magnetic crushing roller. However, the nanocrystalline strip after being crushed by the magnetic crushing rolle...
