Problems solved by technology

[0002] In the prior art, the needle winding mechanism in the automatic winding equipment often adopts a two-half structure. The radial section of the winding core composed of the two halves of the needle winding is generally flat, and the winding of the power lithium battery cell often adopts a constant line. Speed ​​winding method, due to the wide width of the power lithium battery cell, when the flat core is used to wind the base material, the angular velocity changes greatly, which leads to complex tension control and ultimately affects the quality of the equipment winding cell

Abstract

The invention discloses a winding pin mechanism for a winding machine and the winding machine. The winding pin mechanism comprises a winding pin seat, a winding pin assembly and a winding pin tailstock. The winding pin assembly is inserted into the winding pin seat and the winding pin tailstock and comprises a first outwards-winding pin, a first inwards-pressing pin, a second inwards-pressing pin and a second outwards-winding pin, wherein the first outwards-winding pin and the second outwards-winding pin are arranged on the same circumference at 180 degrees, the first inwards-pressing pin is arranged in the first outwards-winding pin, and the second inwards-pressing pin is arranged in the second outwards-winding pin. The winding pin tailstock comprises a fixing seat, a driving device for controlling a sliding block to slide is arranged in the fixing seat and can drive the first inwards-pressing pin and the second outwards-winding pin to get close to or be away from the first outwards-winding pin and the second inwards-pressing pin to clamp or release a base material penetrating through the part between the first inwards-pressing pin and the second inwards-pressing pin. The cross section of a winding core formed by the first outwards-winding pin and the second outwards-winding pin is oval or diamond. The winding pin mechanism for the winding machine and the winding machine are simple in structure and capable of reliably winding high-quality battery cores.

Description

technical field [0001] The invention relates to the field of battery cell manufacturing, in particular to a needle winding mechanism and a winding machine. Background technique [0002] In the prior art, the needle winding mechanism in the automatic winding equipment often adopts a two-half structure. The radial section of the winding core composed of the two halves of the needle winding is generally flat, and the winding of the power lithium battery cell often adopts a constant line. The speed winding method, due to the wide width of the power lithium battery cell, uses a flat core when winding the base material, and the angular velocity changes greatly, which leads to complex tension control and ultimately affects the quality of the equipment winding cell. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a needle winding mechanis...
