In the manufacturing process of the membrane, a membrane winding device is generally adopted to wind the membrane. However, deviation is easy to occur in the process of winding the diaphragm, and finally the diaphragm is not stacked neatly, so that the diaphragm needs to be corrected by using a correction device, and the position of the diaphragm needs to be adjusted in the winding process. In a traditional deviation rectifying mechanism, a sensor is used for detecting the position of the boundary of a diaphragm, when the position of the diaphragm deviates and the deviation exceeds a set value, the position sensor feeds the position of the diaphragm back to a control system in real time, and a servo motor immediately drives the deviation rectifying mechanism to move, so that the position of the diaphragm is corrected.

However, in a high-speed lamination machine, because the left-right movement speed of the lamination platform is very high, and the acceleration of the movement of the diaphragm is very high, the diaphragm is easy to shake, so that the boundary sensed by the position sensor is not the real boundary position of the diaphragm, and the deviation rectification is uneven.
