Technical Field

[0001] The utility model relates to the technical field of NdFeB production and detection equipment, in particular to a surface defect detection device for NdFeB production. Background Art

[0002] NdFeB is a type of ferrite, composed of nickel, cobalt, iron, boron and other elements in a certain proportion. It is an important magnetic material, widely used in industry, scientific research and daily life. NdFeB is a material with excellent properties such as high strength, high saturation magnetization, low coercivity, good thermal stability and chemical stability, and easy processing. NdFeB is widely used in permanent magnet motors, transformers, sensors, magnetic components, maglev trains and other fields.

[0003] As an important magnetic material, the performance and appearance of NdFeB have a direct impact on its application areas. 1. By detecting surface defects, the quality and consistency of NdFeB products can be guaranteed, and the degradation of product performance caused by surface defects can be avoided; 2. By detecting surface defects, potential problems can be discovered and repaired in a timely manner, thereby preventing product failures during use, reducing the risk of product scrapping, and improving product reliability and safety. At the same time, the detection of surface defects also helps to improve the overall appearance quality of the product and enhance its competitiveness in the market; 3. By analyzing and studying the defects, we can find out the causes of the defects and make targeted improvements, thereby improving the manufacturing accuracy and efficiency of the product and reducing production costs.

[0004] Existing NdFeB inspections mainly focus on the detection of defects on its outer surface, which is the main factor affecting product performance and reliability. However, the quality and condition of the inner surface of NdFeB will also directly affect the performance and reliability of the product. Existing inspection equipment often ignores the inner surface inspection of the inner ring of NdFeB, resulting in the quality problems of NdFeB being ignored or being misreported as qualified products, which will lead to some potential safety risks and easily cause failures or damage during use.

[0024] It should be noted that, in this embodiment, by inspecting the inner surface of the annular NdFeB, when the visual detector 43 detects that there are defects on the inner surface of the annular NdFeB, the visual detector 43 sends a signal to the controller, and the controller receives the signal for processing and activates the alarm 44 to alarm, reminding the inspector that there are defects on the inner surface of the annular NdFeB.
