A battery automatic winding equipment

Abstract

The invention discloses an automatic winding device for a battery cell. The automatic winding device comprises a frame, a winding component mounted on the frame, an automatic cell changing component and a controller, wherein the winding component has a winding position and a charging position; the automatic cell changing component comprises a material dividing component and a material conveying component; the material dividing component comprises a storage bin, a material-dividing idler wheel and a material-dividing driving component; the material-dividing idler wheel is arranged at the bottom opening of the storage bin; the material dividing component further comprises a discharging position; the material conveying component comprises a spindle clamping mechanism, a feeding rail and a conveying driving component; the conveying driving component is used for driving the spindle clamping mechanism to move along the feeding rail and conveying a spindle from the discharging position to the charging position; and the material-dividing driving component and the conveying driving component are both connected with the controller. The automatic winding device for the battery cell provided by the invention achieves a full-automatic cell changing function and is very simple and convenient to operate; and in addition, the process efficiency is obviously improved, the labor intensity of workers is reduced, and the stable material dividing, accurate positioning, reliable clamping and stable conveying of the spindle are realized.

Description

Technical field [0001] The invention relates to the field of batteries, in particular to an automatic winding device for electric cores. Background technique [0002] In the production process of the existing cylindrical lithium-ion battery and other batteries, when the cell is formed by the pole piece winding process, part of the winding equipment uses the winding needle to clamp the pole piece and the diaphragm for winding, and cannot directly wind with the mandrel; In another part of the winding equipment that can be wound with a mandrel, when one cell is wound and the core needs to be changed to wind the next cell, it is necessary to manually place the mandrel on the upper material position of the winding head or A semi-automatic mechanism is used to transfer and replace the mandrel. [0003] For the manual core exchange method, the operation process is very cumbersome, which not only affects the process efficiency but also increases the labor intensity of the workers; while t...

Problems solved by technology

[0002] In the production process of the existing cylindrical lithium-ion battery and other batteries, when the battery core is formed by the pole piece winding process, some winding equipment uses the needle to clamp the pole piece and the diaphragm for winding, and it cannot be directly wound with the mandrel; In another part of the winding equipment that can be wound with a mandrel, when the winding of one battery cell needs to be replaced to wind the next battery core, it is necessary to manually place the mandrel on the loading position of the winding head or Transfer and exchange of mandrels with semi-automatic mechanism

[0003] For the method of manual core replacement, the operation process is very cumbersome, which not only affects the process efficiency but also increases the labor intensity of workers; while the use of semi-automatic mechanism for core replacement has a low degree of automation, which is difficult to meet the increasing speed and precision of modern process production. growing development needs
