Abstract

The invention discloses a medium-frequency preheating winding machine for a lithium battery cell. The winding machine comprises a case, a pole piece feeding mechanism, a diaphragm feeding mechanism, awinding mechanism and an electric cabinet, the pole piece feeding mechanism, the diaphragm feeding mechanism and the winding mechanism are all electrically connected with a controller in the electriccabinet; a plurality of medium-frequency heating modules are arranged in the winding mechanism, are electrically connected with the controller, and are used for heating a pole piece and a diaphragm which are conveyed to the winding mechanism by the pole piece feeding mechanism and the diaphragm feeding mechanism. The medium-frequency preheating module is integrated on the winding machine, so thatthe lithium battery cell is preheated in the winding process, preheating furnace equipment is not needed to preheat the cell, the production process of the lithium battery can be effectively reduced,and the production time and cost are saved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production and processing equipment, in particular to an intermediate frequency preheating winding machine for lithium battery cells. Background technique [0002] Compared with traditional storage batteries, lithium batteries have excellent performance advantages such as high working voltage and good cycle life; these excellent performances are largely due to the fact that the working system of lithium batteries belongs to a non-aqueous electrochemical system, so we want to create performance For a good lithium battery, it is necessary to do a good job of drying the battery. Conventional lithium battery production needs to go through winding machine winding, cell preheating, hot pressing and other processes. The cell preheating process requires cell preheating in the preheating furnace equipment, which will lead to lithium battery The production speed becomes slower and the production co...
