Cylindrical battery cell casing method and device

The invention discloses a method and device for loading a cylindrical battery cell into a shell, and belongs to the field of battery manufacturing equipment.The method comprises the steps that a bearing part is arranged on the periphery of a rotating mechanism to vertically bear the battery cell and a battery shell from top to bottom, and a driving mechanism is used for driving the battery cell and the battery shell to axially move oppositely, so that the battery cell enters an inner cavity of the battery shell to form a battery blank; in the axial movement process of the battery cell, the bearing part for bearing the battery cell expands in the radial direction, and the end cover welded on the battery cell can pass through without interference; the battery cell feeding mechanism and the bearing part of the rotating mechanism are used for transferring and conveying battery cells to achieve battery cell feeding, the battery shell feeding mechanism and the bearing part of the rotating mechanism are used for tra
