Abstract

A bump preparation device, comprising a bump preparation mechanism (100) and a compacting mechanism (200) which are sequentially arranged in a conveying direction (X) of a first material (300), wherein the bump preparation mechanism (100) is used for preparing overvoltage bumps (310) on the first material (300); the height (h) of each overvoltage bump is greater than the height of a preset bump, and the preset bump is a bump required by the first material (300); and the compacting mechanism (200) is used for applying a pressure to the overvoltage bumps (310) towards a main body of the first material (300), so that the thickness (a) of the first material reaches a preset value. The device can improve the thickness consistency of electrode sheets and reduce the risk of tab dislocation. Also provided are a battery production system and a winding method.
