Abstract

The invention relates to a method, system and device for detecting defects in a battery. The system comprises an environment simulator, an X-ray source, an image processing device and a computing device. The environment simulator is used for generating a dynamic detection environment of a battery, wherein the environmental conditions of the dynamic detection environment vary with time. The X-ray source is used for generating X rays and irradiating the battery. The image processing device is used for acquiring contour line images of environmental conditions corresponding to the internal structure of the battery at different points. The computing device is used for acquiring the detection result of the internal structure of the battery according to the contour line images of the environmental conditions corresponding to the different time points. Therefore, the quality of the battery after use can be estimated comprehensively and reasonably.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, system and device for detecting defects in batteries. Background technique [0002] In the process of battery packaging, manufacturing process problems such as poor circuit contact and partial extrusion often occur. These battery manufacturing process problems can lead to reduced service life of the battery, bulges and liquid leakage in the battery, and battery explosion in severe cases, seriously endangering the lives of consumers. Therefore, it is very necessary to carry out non-destructive testing on the battery before it is put into the market. [0003] At present, X-ray transmission imaging technology is used in the prior art to detect the internal structure of the battery, and then judge whether the battery is damaged according to the X-ray image of the internal structure of the battery. However, the use of this detection technology cannot guarantee the q...
