Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment, and in particular to a CT inspection device with adjustable magnification. Background Technology

[0002] After the lithium battery is manufactured, it needs to undergo a pass rate test. At this time, a CT inspection device is needed to scan and inspect the lithium battery. After the battery is loaded, the lithium battery is inspected for quality by using a combination of light tube and flat panel detector.

[0003] Existing CT scanners of this type use a rotating ring that can be adjusted 360° to carry a light tube and a flat panel detector. The light tube and detector are symmetrically positioned at the center of the rotating ring. When the lithium battery to be tested is inserted between the light tube and the detector, the light tube provides X-rays as incident radiation. The lithium battery absorbs the radiation energy and emits visible light, which is then detected and processed by the flat panel detector. The light signal is converted into an electrical signal, processed to generate a digital image, and then analyzed by an AI analysis system to determine whether the lithium battery is qualified. However, the magnification of the flat panel detector in existing devices cannot be adjusted. When dealing with different products, the magnification cannot be adjusted for accurate detection, resulting in increased detection errors. Therefore, this solution proposes a CT scanner with adjustable magnification to address the above problems. Utility Model Content
