Abstract

The invention relates to a winding needle, battery cell manufacturing equipment and a battery cell manufacturing method. The winding needle is used for winding a pole piece and comprises a winding needle body comprising a first winding face; an adjusting piece which is configured to be installed on the winding needle body and can move in the axial direction and the radial direction of the winding needle at the same time, wherein the adjusting piece comprises a second winding face, and the first winding face and the second winding face are configured to jointly wind the pole piece; and an actuating piece configured to drive the adjusting piece to move so as to change the relative position of the first winding surface and the second winding surface, so that the winding perimeter of the winding needle is changed. The winding needle can reduce the possibility of dislocation of the tabs or reduce the dislocation quantity of the tabs.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a rolling needle, battery manufacturing equipment and a battery manufacturing method. Background technique [0002] In the production process of power batteries, it is necessary to use winding equipment to wind pole pieces and separators into battery cells. After being wound and pre-pressed and shaped, the battery core has a flat structure. However, during the winding process, the tabs of the pole pieces are misaligned, resulting in positional interference between the tabs and other structural components after the formed battery core is loaded into the casing. Contents of the invention [0003] The present application provides a rolling needle, a cell manufacturing equipment and a cell manufacturing method, which can reduce the possibility of misalignment of tabs or reduce the amount of misalignment of tabs. [0004] On the one hand, the application proposes a win...
