1. A battery winding method, comprising:
winding a membrane composite of a to-be manufactured battery on a winding shaft, the membrane composite comprising a first electrode plate, a first diaphragm, a second electrode plate and a second diaphragm, which are laminated in turn;
each time the membrane composite is wound on the winding shaft by one cycle, acquiring a picture of a current winding layer of the membrane composite by a photographing module arranged at a fixed position, the picture of the current winding layer comprising a first area and a second area which are parallel to each other in a first direction perpendicular to the winding shaft, the first area showing the first electrode plate which is not wound on the winding shaft yet, and the second area showing the second electrode plate which is already wound on the winding shaft;
acquiring position data of a first point in the first area and position data of a second point in the second area according to the picture of the current winding layer, the first point being a middle point of an edge of the first electrode plate in parallel with the first direction, and the second point being a middle point ° Ian edge of the second electrode plate in parallel with the first direction;
converting the position data of the first point to obtain converted position data of a converted first point using a preset conversion matrix corresponding to the current winding layer based on the number of the current winding layers;
calculating data of displacement between the first electrode plate and the second electrode plate based on the converted position data of the converted first point and the position data of the second point;
determining whether the data of displacement is within a threshold value scope; and
winding a next layer of the membrane composite when the data of displacement is within the threshold value scope, or
sending an alarm when the data of displacement is not within the threshold value scope.
