Enameled Copper Wire Coating Layout for Uniform Film Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of foreign matter in the painting die causes non-uniformity in the paint film thickness, leading to appearance abnormalities in enameled copper wire due to hindered solvent vaporization and foaming.
Innovation Solution
A production apparatus with a first and second paint applicator and die configuration, where the first die captures foreign matter and ensures uniform paint application, followed by a baking section to cure the paint, minimizing appearance abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single painting die is used to apply enamel paint, then the production process is simple, but foreign matter can be caught in the die causing non-uniform paint film thickness and appearance abnormalities
Solution Approach 1:
The painting process is divided into two separate stages: a first painting die applies a preliminary paint layer, and a second painting die applies the final paint layer. This segmentation allows each die to function independently, reducing the impact of foreign matter on overall paint film quality and ensuring more uniform thickness throughout the enameled copper wire.
2Manufacturing precision
If the paint film thickness is increased to ensure coverage, then appearance quality improves, but solvent vaporization is hindered causing foaming and appearance abnormalities
Solution Approach 1:
The paint application is segmented into two layers applied at different stages. The first layer provides base coverage, while the second layer ensures uniform final thickness. This segmentation allows for better control of solvent evaporation during baking, preventing foaming while maintaining adequate coverage and uniform appearance.
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
The apparatus effectively suppresses the occurrence of appearance abnormalities in enameled copper wire by maintaining uniform paint film thickness and curing the paint efficiently.
Implementation Method 1
vaporization of a solvent in the enamel paint is hindered
Implementation Method 2
a baking process is subsequently carried out
