Battery inspection apparatus and method, and battery production device

A battery inspection apparatus comprising:

• a tray bearing assembly configured to bear a battery under test and drive the battery under test to move along a first direction;
• a pulsed ray source configured to emit a detection ray in a pulsed manner toward a to-be-inspected region of the battery under test on the tray bearing assembly;
• a detector disposed opposite the pulsed ray source, wherein the two are located on two sides of the tray bearing assembly, respectively, and the detector receives the rays emitted by the ray source and penetrating the to-be-inspected region of the battery under test;
• and
• a first, motor driven, assembly connected to both the pulsed ray source and the detector, wherein the first-, motor driven, assembly is configured to drive the pulsed ray source and the detector to rotate along a circumferential direction of a first rotation axis to acquire detected images of the to-be-inspected region, wherein the first rotation axis is parallel to the first direction;
• wherein a maximum rotation angle A along a circumferential direction of the pulsed ray source and the detector around the first rotation axis satisfies 45°≤λ≤180°.
