Description

Technical Field

[0001] The present invention relates to the technical field of capacitor production and processing, and in particular to a side drum detection component and a detection method for a capacitor upright packaging machine. Background Art

[0002] During the production process of capacitors, when the capacitors are charged with high voltage, the capacitors will implode, causing the outer wall of the capacitors to bulge, which will affect the service life of the capacitors. Therefore, when packaging the capacitors, the capacitors need to be tested to ensure the qualified rate of the shipped products.

[0003] China application publication number CN114578178A, application publication date is June 3, 2022, which discloses a bulging test device for aluminum electrolytic capacitors, belonging to the field of capacitor production technology. The present invention can test the capacitor by powering on it. When the current is large, the capacitor generates temperature, and then expands due to the liquefaction of the electrolyte to form a bulge. When the capacitor bulges, the bulging area squeezes the original column of the resistance, and the original column of the resistance squeezes the warning liquid in the injection cylinder into the inner filling bag for expansion. The variable magnetic cover expands under the expansion of the inner filling bag, and the magnetic field is enhanced. On the one hand, it reacts to the original column of the resistance to mark the bulging area, and on the other hand, the expanded variable magnetic cover is warned and recorded by the camera.
