Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum electrolytic capacitor technical field especially relates to a device of automatic detection aluminum electrolytic capacitor side drum. BACKGROUND

[0002] As a key component in the electronic industry, the stability and reliability of aluminum electrolytic capacitors are crucial for the operation of the entire electronic system. During the production process, the aging stage is a critical step to ensure the stability of capacitor performance, improve the withstand voltage capability, and eliminate defective products. The aging process not only forms or repairs the oxide film on the aluminum foil surface to enhance its electrical properties, but also serves as a strict quality control link, enabling the identification and elimination of capacitors that do not meet performance standards. However, in the aging stage, aluminum electrolytic capacitors may exhibit two major types of defects: poor electrical performance and poor appearance. Poor electrical performance typically manifests as electrical parameters of the capacitor not meeting specification requirements, such as low capacitance value and excessive leakage current. These issues can be fully inspected using existing electrical performance testing equipment, and unqualified capacitors can be individually eliminated.

[0003] Poor appearance is more complex, including drum bottom, drum glue particles, and side drum. Poor drum bottom and drum glue particles typically exhibit obvious deformation or damage on the appearance of the capacitor, and these issues can also be fully inspected and eliminated using existing appearance inspection equipment. However, poor side drum is a more challenging problem. Poor side drum refers to capacitors that have undergone breakdown in a local area and have been repaired through aging, although their electrical performance parameters have returned to normal, they still exhibit bulging or deformation in appearance. Since these capacitors exhibit normal performance in electrical performance testing, they are easily misjudged as good products. However, their actual performance may have been compromised, and if they fail in subsequent use, they will pose a threat to the stability of the entire electronic system.

[0004] Currently, there is a lack of effective automatic screening and elimination methods for capacitors with poor side drum. The main reason is that the manifestations of poor side drum are diverse, and there is no clear correspondence between them and electrical performance parameters. Therefore, existing automatic inspection equipment cannot accurately identify and eliminate such defective products. To address this issue, most manufacturers still use manual visual inspection. However, this method is not only inefficient but also susceptible to human factors such as inspector fatigue and lack of experience. At the same time, as the production scale of capacitors expands, the labor cost required for manual inspection is also increasing, further increasing manufacturing costs. Therefore, developing a device or method that can automatically and accurately identify and eliminate aluminum electrolytic capacitors with poor side drum is of great significance for improving capacitor production quality and reducing manufacturing costs. This may require the combination of advanced image processing and machine learning technologies to accurately analyze and judge the appearance of capacitors, thereby achieving automated quality control.
