Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery detection, in particular to a multi-angle detection device for lithium battery production. Background Art

[0002] Currently, the lithium battery manufacturing industry uses CT technology to detect the internal quality of battery cells. During the inspection process, the measured point of the battery cell needs to be rotated relative to the CT ray source to construct a three-dimensional data model.

[0003] Typically, a battery cell has multiple test points, especially rectangular cells, which require testing at all four corners. Traditional CT equipment requires manual adjustment of the cell position to ensure that the four corners coincide with the axis of the radiation source and maintain the same distance from the radiation source's emission port. This method not only leads to low detection efficiency, but also causes the battery cell to be clamped multiple times, making it difficult to ensure positioning accuracy and posing a risk of damaging the cell surface. There are some automated solutions on the market, but they cannot adjust the distance between the measured corner and the radiation source's emission port, or the measured corner does not rotate but only outputs planar data. These solutions are not suitable for testing larger battery cells. Utility Model Content
