Pole piece correction system and method

Abstract

The application relates to the technical field of batteries and discloses a pole piece deviation rectifying system and method, which comprises a processor and a deviation rectifying mechanism, a deviation rectifying sensor, an image collector and a winding device arranged in sequence according to the pole piece walking direction. The deviation rectifying sensor is used for acquiring the pole piece edge position of a current pole piece material belt and sending the pole piece edge position to the processor. The image collector is used for acquiring the pole piece deviation of a historical pole piece material belt in a free end area and sending the pole piece deviation to the processor, wherein the free end area is an area between the deviation rectifying sensor and the winding device. The processor is used for determining a deviation rectifying target value based on the pole piece edge position and the pole piece deviation through a preset deviation rectifying model, wherein the preset deviation rectifying model is a model obtained by training based on historical deviation rectifying information. The deviation rectifying mechanism is used for rectifying the current pole piece material belt based on the deviation rectifying target value, so that the accuracy of pole piece deviation rectifying can be improved, and the pole piece deviation rectifying effect can be improved.
