Claim 5:
6. A battery winding system, comprising:
a winding shaft for winding; a layer of membrane composite of a to-be manufactured battery, the membrane composite comprising a first electrode plate, a first diaphragm, a second electrode plate and a second diaphragm which are laminated in turn;
a photographing module arranged at a fixed position, configured to take a picture of a current winding layer each time the membrane layer composite is wound on the winding shaft by a cycle, the picture of the current winding layer comprising a first area and a second area which 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; and
a control unit, configured to:
acquire position data of a first point in the first area and position data of a second point is acquired in the second area according to the photographed 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 of an edge of the second electrode plate in parallel with the first direction;
convert the position data of the first point to obtain converted position data of the converted first point using a preset conversion matrix, corresponding to the current winding layer, based on the number of the current winding layers;
calculate 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;
determine whether the data of displacement is within a threshold value scope; and
control the winding shaft to wind a next layer of the membrane composite when the data of displacement is within the threshold value scope, or
send an alarm when the data of displacement is not within the threshold value scope.
