Abstract

The present application provides a battery cell winding device, including: a winding needle, which is in a winding station and can rotate continuously; a material pressing piece, which is arranged on the radial side of the winding needle; a first driving component, which is connected to the material pressing piece in transmission, and can drive the material pressing piece to approach and move away from the winding needle, so that the material pressing piece presses the diaphragm on the outer peripheral surface of the winding needle and is pulled out by the diaphragm; a second driving component, which is connected to the material pressing piece in transmission, and can drive the material pressing piece to rotate around the axis of the winding needle; the rotational angular velocity of the material pressing piece is equal to that of the winding needle, so that the diaphragm is wound on the winding needle. With such an arrangement, the diaphragm is pressed tightly against the winding needle by the material pressing piece, and rotates synchronously with the winding needle, and then the diaphragm is wound on the winding needle, without the need to set a vacuum adsorption mechanism on the winding needle, which is conducive to simplifying the structure of the winding needle and improving the structural strength of the winding needle.
