Workpiece Cleaning Method Skipping Unrequired Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning methods require lengthy cleaning times due to the application of cleaning jets to all cleaning points, even when only a few points contain foreign matter, leading to unnecessary cleaning of unrequired points.
Innovation Solution
A cleaning method utilizing a numerical control program and an arithmetic device to identify and skip unrequired cleaning points by setting binary variables based on the presence of foreign matter, allowing the cleaning device to focus on specific points with adhered foreign material using an X-ray or γ-ray CT scanner and a moving nozzle system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning liquid is jetted to all cleaning points in order, then all cleaning points are cleaned thoroughly, but cleaning time becomes excessively long
Solution Approach 1:
The system performs preliminary detection using a scanner to identify which cleaning points actually have foreign matter before the cleaning process begins. This preliminary action allows the control device to create a optimized cleaning path that only visits necessary cleaning points, eliminating wasted time on clean points while ensuring all contaminated points are cleaned.
Solution Approach 2:
The control device skips cleaning sections corresponding to cleaning points without foreign matter by using conditional branches in the numerical control program. When the detection result shows no foreign matter at a cleaning point, the system rushes through that section without executing the cleaning jet, thereby significantly reducing overall cleaning time while maintaining cleaning effectiveness at contaminated points.
2Reliability
If cleaning is performed at all predetermined cleaning points, then no cleaning point is missed, but unnecessary cleaning of clean points occurs
Solution Approach 1:
The system applies local quality by treating different cleaning points differently based on their actual contamination status. Instead of uniform cleaning at all points, the control device determines which specific cleaning points require cleaning based on detection results, and applies cleaning only to those locations. This localized approach maintains reliable cleaning coverage while eliminating energy waste on already clean surfaces.
Solution Approach 2:
The system uses feedback from the scanner's detection results to control the cleaning process. The detection unit scans the workpiece to identify foreign matter locations, and this feedback information is used by the control device to dynamically adjust the cleaning path and determine which cleaning sections should be executed. This closed-loop feedback mechanism ensures cleaning coverage is maintained while improving efficiency.
