Guide Roller Winding Conveying Unit for Battery Electrode Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional winding devices cause breakage of electrode plates during the manufacturing process of rechargeable batteries for electric vehicles due to the electrode parts being wound and moved upwardly, leading to errors and reduced production rates.
Innovation Solution
A winding conveying unit with a guide roller positioned on the external surface of the conveying roller to guide the electrode plate, preventing breakage by adjusting the mounting angle and force application based on the conveying path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electrode plate is conveyed using a conventional winding device, then the manufacturing process can proceed, but the electrode breaks due to upward movement during winding
Solution Approach 1:
A guide roller is introduced as an intermediary component between the conveying roller and the electrode plate. The guide roller contacts the electrode plate at multiple points and guides it through the winding process, preventing upward movement and breakage while maintaining manufacturing continuity
Solution Approach 2:
The guide roller is positioned at an inclined angle relative to the conveying roller axis, creating a three-dimensional guiding structure. This angular arrangement allows the guide roller to effectively constrain the electrode plate's upward movement while accommodating the winding geometry
2Use of energy by moving object
If the electrode plate area is increased to improve capacity, then the energy density increases, but the electrode becomes more prone to breakage during conveying
Solution Approach 1:
The guide roller serves as a protective intermediary that distributes mechanical stresses across multiple contact points on the electrode plate, preventing concentration of forces that would cause breakage in larger, more fragile electrodes
Solution Approach 2:
The guide roller is positioned to contact the electrode plate before critical stress points are reached during conveying. This preemptive guidance prevents excessive tension and bending forces from developing, cushioning the electrode against breakage before it occurs
