Coating Device Joint Ring Insulation for Condensation Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary atomization-type coating devices face issues with condensation forming on the joint ring, a critical connection between the robot arm and rotary atomization head, which is not adequately addressed by existing solutions, leading to operational and maintenance burdens and increased risk of temperature reduction.
Innovation Solution
Incorporating an insulating member between the joint ring body and cover member, with a second chamber to isolate temperature changes and an air supply unit for air-purging the second chamber, preventing temperature reduction and condensation on the outer surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a high-temperature adiabatic air passage is positioned on the outside of a discharge air passage, then condensation on the device outer surface is suppressed, but the device complexity increases due to additional air passages and drive mechanisms
Solution Approach 1:
The patent extracts the harmful cold exhaust air from the discharge passage and redirects it through a separate bypass passage that does not contact the outer surface, eliminating the source of condensation without adding complex heating or insulation systems to the outer surface
Solution Approach 2:
The bypass passage acts as an intermediary channel that allows the cold exhaust air to be diverted away from the outer surface area, preventing direct thermal interaction between the cold air and the device exterior, thus avoiding condensation without requiring additional active control mechanisms
2Object-affected harmful factors
If conventional condensation suppression methods are applied to the joint ring, then operational burden increases and maintenance becomes more difficult
Solution Approach 1:
The patent extracts the exhaust air flow path away from the joint ring area by positioning the discharge port and bypass passage to exclude the joint ring from the cold air trajectory, preventing condensation on this critical connection component without adding operational complexity
Solution Approach 2:
The exhaust air flow itself serves the dual function of driving the atomization process and simultaneously preventing condensation on surrounding components including the joint ring, by creating a protective air curtain and maintaining local temperature without requiring additional heating or insulation systems
