[0002] In the manufacturing industries such as automobiles, motorcycles, engineering machinery and defense products, magnetic particle inspection of metal parts with a diameter range of Φ10mm to Φ500mm is a key link to ensure product quality and safety. Magnetic particle inspection technology uses the interaction between magnetic field and magnetic powder to effectively detect defects such as cracks and inclusions on the surface of materials, which is of great significance for ensuring product reliability and extending service life.

[0003] However, in the current practice of magnetic particle inspection, there are a series of challenges and limitations, especially when dealing with large and small workpieces. Traditional magnetic particle inspection machines are usually equipped with a UV light source device connected by a fixed screw, which requires the operator to manually lift the workpiece to the effective radiation illumination range of the UV lamp for inspection. This process is not only time-consuming and laborious, but also because the workpiece is often heavy, the movement process not only increases the labor intensity of the operator, but also easily causes the worker's hands to be injured or the product to be damaged, posing a major safety hazard.

[0004] In addition, fixed light source devices limit the flexibility and coverage of detection. For workpieces with complex structures and various shapes, especially those with tricky angles or oblique holes, traditional equipment often fails to achieve ideal detection results, easily resulting in omissions of detection parts, and reducing detection efficiency and accuracy. These problems not only affect the smoothness of the production line, but may also pose a threat to the quality and safety of the final product. Utility Model Content
