Embodiment

[0046] see figure 1 , figure 1 It is a schematic perspective view of the three-dimensional structure of the variable diameter needle winding mechanism 10 provided by the embodiment of the present invention.

[0047] The embodiment of the present invention provides a needle winding mechanism 10 with a variable winding diameter. The needle winding mechanism 10 with a variable winding diameter has the characteristic of being able to adjust the winding diameter. The needle winding mechanism 10 with variable winding diameter can be applied to electric core production scenarios such as winding devices. When the needle winding mechanism 10 with variable winding diameter is applied to a winding device (not shown in the figure), the winding of the winding device The driving member can drive the needle winding assembly 11 of the variable winding diameter needle winding mechanism 10 to rotate to perform the work of winding the battery core. Since the winding device adopts the variable w...

Abstract

The invention discloses a winding needle mechanism with a variable winding diameter and a winding device, and relates to the technical field of battery production. The winding needle mechanism with the variable winding diameter comprises a winding needle assembly and an ejector pin assembly. The winding needle assembly comprises a winding main body, a winding needle shell and a reducing adjusting piece, and the winding needle shell is slidably connected with the winding main body and can slide along the radial direction of the winding main body. The reducing adjusting piece is movably connected to the winding main body and is connected with the winding needle shell. The ejector pin assembly can drive the variable-diameter adjusting piece to move relative to the winding main body, and therefore the variable-diameter adjusting piece drives the winding needle shell to slide along the radial direction of the winding main body. The winding needle mechanism with the variable winding diameter and the winding device have the advantage that the winding diameter can be adjusted.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a needle winding mechanism and a winding device with a variable winding diameter. Background technique [0002] In the production process of lithium batteries, the wound battery core is formed by winding the diaphragm and positive and negative electrodes through the needle winding mechanism of the winding machine. The winding diameter of the needle winding mechanism is related to the alignment of the pole tabs and the size of the battery core. , so the roll diameter of the needle roll mechanism directly affects the quality of the cell. However, the winding diameter of the existing needle winding mechanism is difficult to adjust. [0003] In view of this, it is particularly important to develop and design a needle winding mechanism and a winding device with a variable winding diameter that can solve the above technical problems. Contents of the invention [0004] Th...
