Air Blow Nozzle Trajectory Control for Dry Thermal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In thermal processing devices, the use of liquids during processing often results in the workpiece becoming wet, leading to poor appearance, dirt stains, and potential rust, requiring manual wiping post-processing.
Innovation Solution
A thermal processing device and method that incorporates a container for the workpiece, an air blow nozzle, and a drive mechanism, where the air blow nozzle blows gas onto the workpiece after processing, with its movement trajectory controlled to remain within the planar shape of the workpiece, effectively removing any liquid residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid is used during thermal processing to cool the workpiece and prevent dust scattering, then processing stability is improved, but the workpiece surface becomes wet leading to poor appearance and potential rust
Solution Approach 1:
The patent applies preliminary action by introducing a drying process before the workpiece is completely wetted with liquid. The drying unit removes moisture from the workpiece surface during or immediately after processing, preventing the harmful effects of wetting while maintaining the benefits of liquid cooling and dust suppression during the actual thermal processing operation
2Object-affected harmful factors
If liquid is used during processing to suppress dust scattering, then dust control is improved, but manual wiping work is required after processing
Solution Approach 1:
The patent implements self-service by incorporating an automated drying unit that performs the drying function without manual intervention. The drying unit is integrated into the processing system and automatically removes liquid from the workpiece surface, making the system self-sufficient for moisture removal and eliminating the need for separate manual wiping operations
Solution Approach 2:
The patent replaces the manual mechanical wiping process with an automated drying mechanism. The drying unit uses controlled airflow or other automated methods to remove liquid from the workpiece surface, substituting human labor with an automated mechanical or physical process that is more efficient and consistent
3Temperature
If liquid is used during thermal processing, then cooling effect is improved, but dirt stains and rust are generated on the workpiece surface
Solution Approach 1:
The patent applies preliminary action by implementing a drying step before dirt stains and rust can form on the workpiece surface. The drying unit removes liquid promptly after processing, preventing the chemical and physical changes that lead to staining and corrosion, while the liquid cooling function operates effectively during the processing phase

AI summary
A container supports a workpiece and is capable of storing a transmission inhibition liquid. An air blow nozzle blows gas to the workpiece supported by the container. A drive mechanism moves the air blow nozzle. A controller controls the drive mechanism so as to limit a movement trajectory of the air blow nozzle during the gas blowing to the workpiece by the air blow nozzle within a planar shape of the workpiece.
