Classification: CPC G  H  Y | IPC G

Claim 9:
10. A deviation detection device, wherein
it is used to detect positional deviation of an electrode assembly during winding, the electrode assembly comprising a first electrode sheet, a second electrode sheet and a separator, and
the deviation detection device comprises:
a first camera and a second camera for obtaining a first image and a second image respectively, the first image comprising an image of a first electrode sheet of an electrode assembly during winding;
the second image comprising an image of a second electrode sheet of the electrode assembly during winding; and
a deviation determining unit configured to:
determine whether the first camera and the second camera are deviated according to a distance from a reference point in the first image to a specific position and a distance from a reference point in the second image to the specific position; and
determine whether the electrode assembly is deviated according to a vertical distance from the reference point in the first image to a boundary of the first electrode sheet and a vertical distance from the reference point in the second image to a boundary of the second electrode sheet in response to determining that the first camera and the second camera are not deviated.
