TH95805B - Cylindrical battery leak detection method - Google Patents

Abstract

Cylindrical battery leak detection method That when transported through a mechanism Detect fluid leaks (12) by aligning the center of the cylinder battery's axes (Ba), x-ray radiation (34) to the closed end (33) of the bellows battery. (Ba) and fluorescence X-rays (40), exiting from the side of the opening (33), projected from the detect window (35) into the detector (39) in the fluorescence radiation (40) projected into. Here we examine the presence of fluorescent X-rays (40) in response to the ingredients in the electrolytic liquid, where separate analysis results are used to determine the liquid leakage of the cylindrical battery (Ba). ) The length proportions (L1, L3, L5) that support the conveying direction of the cylindrical battery (Ba) are smaller than the distance (C1, C2) of the cylinder battery (Ba). Long (L2, L4, L6) that supports the direction perpendicular to the conveyor direction. At large Than the external proportions (R1, R2) of the cross-sectional shape of the perpendicular direction to the central point of the axis of Cylindrical battery (Ba) can also judge the liquid leakage of a cylindrical battery. How to quickly and accurately extract fluorescence X-rays
