Lamination Cooling Airflow Layout to Prevent Upstream Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamination-forming systems suffer from contamination of the lamination processing stage due to cooling air flowing perpendicularly to the object, which can lead to particle entry and defects.
Innovation Solution
A lamination-forming system that uses a cooling unit with air flow generation means to direct cooling air at an inclined angle relative to the conveyance direction, preventing air from flowing towards the upstream lamination apparatus and reducing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling air is caused to flow from cooling fans in a direction perpendicularly to the object, then cooling efficiency is improved, but contamination of the lamination processing stage occurs
Solution Approach 1:
The cooling fans are arranged asymmetrically with respect to the conveyance direction, with fans positioned at different locations (upstream side and downstream side) blowing air in opposite directions. This asymmetric arrangement creates a balanced airflow pattern that prevents contamination while maintaining cooling efficiency.
Solution Approach 2:
The cooling function is segmented into multiple cooling fans distributed at different positions along the conveyance direction. Instead of using a single cooling source, the system divides the cooling task among multiple fans that work cooperatively to achieve both cooling and contamination prevention.
2Temperature
If cooling fans are positioned close to the lamination stage, then cooling effectiveness is improved, but particle generation and contamination increase
Solution Approach 1:
The carrier film acts as an intermediary medium between the cooling fans and the lamination stage. The cooling fans blow air onto the carrier film, which then transfers the cooling effect to the lamination stage indirectly, preventing direct contact between high-velocity air flow and the lamination stage that would cause particle generation.
Solution Approach 2:
The cooling approach is shifted from direct air flow onto the lamination stage to cooling the carrier film that carries the lamination stage. This dimensional shift allows cooling to occur through the carrier film medium, reducing direct air impact and particle generation.
