Title:
WINDING APPARATUS, WINDING DEVICE AND WINDING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/142084
Kind Code:
A1
Abstract:
Embodiments of the present application provide a winding apparatus, a winding device and a winding method. The winding device comprises: a pair of outer needles which are opposite to each other in a first direction, the periphery of each outer needle being used for winding an electrode assembly; an adjustment member which is configured to reciprocate in a second direction to drive the pair of outer needles to move away from or towards each other and increase or decrease the distance between the pair of outer needles, the second direction being perpendicular to the first direction; a pair of inner needles which are arranged between the pair of outer needles, oppositely arranged in the first direction, and configured to move independently of the adjustment member so as to clamp or release the electrode assembly; and a first elastic reset member which is configured to apply elastic force in the first direction to at least one inner needle, so that the pair of inner needles tend to move close to each other. The technical scheme of the present application can improve the yield of the electrode assembly and enhance the production efficiency.
