Embodiment Construction

[0015] The present invention will be further described in detail below through embodiments in conjunction with the accompanying drawings.

[0016] See figure 1 and figure 2 , the winding device of the present invention is a single-station semi-automatic winding machine. In one embodiment, the winding device includes a winding module, a station conversion module and a mounting plate 001 . The winding module includes a first driving mechanism, a winding needle 012 and a needle limit mechanism, and the station conversion module includes a second driving mechanism, wherein the first driving mechanism is coupled to one end of the winding needle 012 to drive the winding needle 012 to rotate, and the winding The other end of the needle 012 is radially limited by the needle winding limit mechanism during winding, and the second driving mechanism is coupled to the first driving mechanism to drive the first driving mechanism to move the winding needle 012 in the axial direction.

Abstract

The invention discloses a winding device of a battery electric core, comprising a winding module and a station conversion module, wherein the winding module comprises a first driving mechanism, a winding needle and a winding needle limiting mechanism; the station conversion module comprises a second driving mechanism; the first driving mechanism is coupled with one end of the winding needle to drive the winding needle to rotate; the other end of the winding needle is radially limited by the winding needle limiting mechanism during winding; and the second driving mechanism is coupled with the first driving mechanism to drive the first driving mechanism to move along an axial direction by carrying with the winding needle. The invention has simple structure and high winding efficiency and is beneficial to manufacturing a square lithium battery with a relatively-larger pole lug forming part dimension.

Description

technical field [0001] The invention relates to a lithium battery production equipment, in particular to a battery cell winding device. Background technique [0002] With the continuous promotion of lithium battery applications, the production process requirements of lithium batteries are also getting higher and higher. Existing winding equipment is usually only aimed at making ordinary square lithium battery cells with the direction of the mandrel as the length direction and the end of the tab as the width direction, that is, the longitudinal length of the battery mandrel is greater than the transverse length of the tab forming part . For example, the common double-station winding equipment, due to the space constraints and obstacles brought about by the complexity of its station conversion structure, is not convenient to make a square lithium battery with a larger tab forming part than the mandrel length. Contents of the invention [0003] The technical problem to be s...
