/Bump Preparation Apparatus, Battery Production System, And Winding Method
Abstract

A bump preparation apparatus includes a bump preparation mechanism and a compacting mechanism that are sequentially arranged along a conveying direction of a first material, where the bump preparation mechanism is configured to prepare overpressed bumps on the first material, a height of each overpressed bump is greater than a height of a preset bump, the preset bump is a bump required by the first material, and the compacting mechanism is configured to apply a pressure to the overpressed bumps toward a main body portion of the first material, such that a thickness of the first material reaches a preset value.
