Description

Technical Field

[0001] The utility model relates to the technical field of automatic detection equipment, in particular to a full-automatic coupled inductance test and defect detection machine. Background Art

[0002] An inductor is a coil structure that generates inductance. Usually, the inductor is wound on a magnetic ring. Inductors are often used in various motors, fluorescent lamp ballasts, various large and small transformers, televisions, etc. However, existing winding machines can easily damage the enameled wire when winding on the magnetic ring, resulting in the small magnetic ring inductor being unable to withstand high voltage when in use. In severe cases, it can cause the coil to short-circuit, posing a threat to life and property. Therefore, small magnetic ring inductors need to be subjected to electrical testing and defect detection after production to remove defective products. Currently, electrical testing is often performed manually. The manual detection method not only has complicated procedures, but also has low detection efficiency and poor detection accuracy. In addition, a high-voltage detection pen needs to be held in the electrical detection process, which poses a certain risk to the staff during the detection process. In addition, the manual detection method has high labor intensity and cannot meet the detection needs of large quantities. After the electrical test, it is also necessary to detect whether there are defects on the outer surface of the magnetic ring inductor. After the magnetic ring inductor passes the detection, qualified products need to be packaged. Utility Model Content
