Pole piece extension device and method, control device and pole piece rolling equipment

The invention relates to the technical field of battery manufacturing, and provides a pole piece extension device and method, a control device and pole piece rolling equipment, and the pole piece extension device comprises a transmission device, a heating device, a temperature measuring device and a controller. The blank area is heated through the heating device to improve the ductility, rolling contact is avoided, the temperature measuring device is used for measuring the temperature of the heated blank area, the controller is connected to the temperature measuring device, the heating device and the transmission device, and combined control over the belt conveying speed and the heating temperature of the blank area can be achieved according to a preset working mode. The softening effect of the aluminum foil in the blank area is optimized, the elongation and the tensile strength of the blank area are guaranteed, the problems of wrinkling and warping are effectively solved, then the frequency of rolling belt b
