Document Type and Number:
WIPO Patent Application WO/2024/036746
Kind Code:
A1
Abstract:
The present application relates to the technical field of battery preparation, and discloses a winding method and a winding system. The method comprises: obtaining, in real time, a first parameter and a second parameter of each electrode assembly on a winding shaft, wherein the first parameter is any one of the number of winding layers, the length of a diaphragm, and the winding diameter, and the second parameter is one or both of the remaining two of the number of winding layers, the length of the diaphragm, and the winding diameter; comparing the second parameter with a corresponding preset parameter range, respectively, wherein the preset parameter range is a range of a second parameter corresponding to a first parameter of a preset standard model corresponding to the electrode assembly; and if the second parameter is out of the preset parameter range, adjusting a diaphragm to be wound of the corresponding electrode assembly. When the winding of the diaphragm to be wound is completed, the deviation of the early-stage electrode assembly can be compensated for, so that a plurality of finally completed electrode assemblies can meet standard requirements, thereby reducing the possibility of deviation of finished electrode assemblies, and improving the production efficiency.
