The invention discloses a diaphragm winding method, and belongs to the technical field of diaphragm production. And when the diaphragm surface of the diaphragm is wrinkled, the traction tension F1 of the traction tension roller is reduced by 0.3-0.6 time from the initial tension value. The direction of membrane surface wrinkles is observed, and if membrane surface wrinkles appear on the driving side perpendicular to the moving direction of the membrane, the deviation rectifying width L of the micro-swing deviation rectifying suspension is lowered; and if membrane surface wrinkles appear on the non-driving side perpendicular to the movement direction of the membrane, the deviation correction width L of the micro-swing deviation correction suspension is adjusted upwards until the membrane surface wrinkles disappear. According to the method, the diaphragm surface wrinkle defect in the winding process of the diaphragm can be improved.
