Segmented Air Outlet Apparatus for Targeted Battery Electrode Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drying devices struggle to provide targeted drying conditions for different coating areas on battery electrode sheets, leading to potential drying cracking or failure, which affects the quality of the coating process.
Innovation Solution
An air outlet apparatus with a wind speed adjusting assembly that divides the air outlet cavity into sections, allowing each section to be aligned with specific coating areas and adjusting wind speed by opening or closing air outlets of varying cross-sectional areas to meet the unique requirements of each area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single air outlet is used for the entire coating area, then the device structure is simple, but different coating areas cannot receive targeted drying conditions
Solution Approach 1:
The air outlet is divided into multiple independent air outlet sections along the first direction, with each section corresponding to a specific coating area. Each section has its own wind speed adjusting assembly that can independently control the opening area, enabling targeted drying for different coating areas while maintaining a relatively simple overall structure.
2Productivity
If wind speed is increased for faster drying, then drying efficiency improves, but drying quality deteriorates due to cracking in sensitive coating areas
Solution Approach 1:
Each air outlet section is equipped with an independent wind speed adjusting assembly that can locally regulate the opening area. This allows different coating areas to receive appropriately adjusted wind speeds - higher for areas requiring fast drying and lower for areas sensitive to cracking - thereby achieving both high drying efficiency and excellent drying quality simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures each coating area is dried under suitable conditions, improving drying quality by adjusting wind speed to match the specific needs of different coating areas, thereby preventing cracking and ensuring efficient drying.
Implementation Method 1
each wind speed adjusting assembly is configured to open or close at least some air outlets, so as to adjust outlet wind speed of each air outlet section
Implementation Method 2
The hot air generated by the drying device is discharged to a coating area on a surface of the substrate, and then a solvent in a wet coating is dried and removed
