Description

Technical Field

[0001] The invention relates to the technical field of intelligent detection and evaluation of NdFeB electroplating blanks, and in particular to an intelligent detection system and method for NdFeB electroplating blanks. Background Art

[0002] NdFeB is a high-performance rare earth permanent magnet material, which is widely used in various electronic and electrical equipment. The raw materials for manufacturing NdFeB are mainly neodymium, iron and boron elements mixed in a certain proportion. After process treatment, NdFeB electroplating blanks are obtained. Whether the quality of NdFeB electroplating blanks meets the design requirements has an important impact on subsequent processing and practical applications. Therefore, it is necessary to conduct intelligent detection of NdFeB electroplating blanks to find potential problems.

[0003] The existing technology for detecting NdFeB electroplating blanks can meet the basic requirements, but there are also some potential problems, which are specifically reflected in the following aspects. On the one hand, the existing technology for detecting NdFeB electroplating blanks is mostly limited to appearance detection, and uses image recognition and other technologies for analysis, ignoring the actual data of various parameters of the magnetic properties of NdFeB electroplating blanks on the quality of the subsequent NdFeB finished products. At the same time, it ignores the actual data of various parameters of the alloy composition of NdFeB electroplating blanks on the performance, stability and life of NdFeB finished products. The detection of NdFeB electroplating blanks is limited, resulting in the risk that the quality of the produced NdFeB products does not meet the design requirements and the actual use effect does not meet the demand.

[0004] On the other hand, in actual applications, the consistency in quality of NdFeB electroplating blanks from the same production batch ensures stability during use. The existing detection system ignores the importance of consistent quality of NdFeB electroplating blanks from the same production batch, and fails to comprehensively evaluate the quality consistency coefficient of NdFeB electroplating blanks from the same production batch based on the quality compliance coefficient of each quality-compliant NdFeB electroplating blank from the same production batch. As a result, large fluctuations in the quality coefficients of each NdFeB electroplating blank from the same production batch cannot be detected, leading to potential risks of accidents during actual use in the later stage. Summary of the invention

[0029] Furthermore, the alloy composition compliance index of the target NdFeB electroplating blank is obtained based on the actual proportion data of each parameter of the alloy composition of the target NdFeB electroplating blank.
