Winding needle mechanism

Abstract

The invention relates to a winding needle mechanism. The winding needle mechanism comprises a winding drum assembly, a fixed clamping part, a movable clamping part and a first sliding block. The winding drum assembly is divided into a first half winding drum and a second half winding drum in the circumferential direction. The fixed clamping part is accommodated in the first mounting groove and is fixedly connected with the first half winding drum; the movable clamping part is located on the side, close to the second half winding drum, of the fixed clamping part; the first sliding block is fixedly connected with the movable clamping part; and the first sliding block is movably connected with one end, in the axial direction, of the first half winding drum, and the first sliding block is elastically connected with the second half winding drum, so the first sliding block can move relative to the second half winding drum and the first half winding drum in the radial direction of the winding drum assembly. The clamping or loosening state of the movable clamping part and the fixed clamping part and the diameter change of the winding drum assembly can be controlled through the relative movement between the first sliding block and the second half winding drum, the winding needle mechanism is very simple and convenient, the problem that more interference sources exist in winding due to the fact that the size of the winding needle mechanism is large is effectively solved, the machining difficulty is small, and the hardware cost is low.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery cell winding equipment, in particular to a needle winding mechanism. Background technique [0002] Lithium-ion batteries have the advantages of light weight and good safety performance, so they are widely used in mobile electronic devices such as Bluetooth, 2G / 3G mobile phones, notebook computers, tablet computers, cameras, and portable mobile power supplies. At present, in lithium battery equipment, batteries composed of batteries formed by winding are called winding batteries, and winding batteries are also called batteries. The battery core in the form of winding can make the performance of the lithium battery stable and the manufacturing efficiency high. The needle winding mechanism in the winding machine clamps the separator of the battery by setting a fixed clamping part and a movable clamping part that can move relative to the fixed clamping part, and then through the two rolls...

Problems solved by technology

[0003] Based on this, it is necessary to address the large size of the mechanism and more sources of interference in the winding due to the complexity of the moving parts controlling the movable clamping part and the cumbersome control process in the needle winding mechanism, which makes the processing difficult and the hardware cost high technical problem, providing a needle rolling mechanism
