Automatic winding device for battery cell

Abstract

A core automatic winding device comprises a rack and a winding assembly (1) mounted on the rack, the winding assembly (1) has a winding position and a skip position, the winding assembly (1) also has an automatic core change assembly (2) and a controller, the automatic core change assembly (2) comprises a core distribution assembly and a core transfer assembly, the core distribution assembly comprises a bunker (211), a core distribution trolley (210), and a core distribution drive part (212), the core distribution trolley (210) is provided at the bottom opening of the bunker (211),the core distribution assembly also has a discharge position (217), the core transfer assembly comprises a pivot clamping device, a core transfer track (22), and a core transfer drive part which drives the pivot clamping device to move along the core transfer track (22), so the pivot is transferred from the discharge position (217) to the core transfer drive part (221), and the core distribution drive part and the core transfer drive part (221) are both connected to the controller. The automatic core-changing assembly makes the core automatic winding device automatically change the core, the operation is simple and convenient, the process efficiency is improved, and the stable distribution, accurate holding, reliable clamping, and smooth transfer of the core are achieved.

Description

technical field [0001] The invention relates to the battery field, in particular to an automatic battery winding device. Background technique [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 The mandrel is transferred and replaced by a 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 us...

[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
