Articulating Arm Fixture for Window Weld Flash Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window frame and sash cleaning systems face challenges in consistently removing weld flash due to variances in profile dimensions and misalignment during the welding process, leading to inconsistent cleaning results and interference with further assembly processes.
Innovation Solution
A window processing system featuring a six-axis articulating arm with a tool support fixture assembly, equipped with multiple tools and sensors for precise movement and operation, allows for flexible tool utilization and automatic recognition of frame profiles to perform cleaning operations efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of tools are used to remove weld flash, then cleaning capability is improved, but device complexity increases
Solution Approach 1:
The patent implements a tool assembly that can hold and switch between multiple types of cleaning tools (saw blades, knives, end mills, router bits) to remove weld flash from different locations and orientations of window frames. This multi-functional tool assembly resolves the contradiction by providing versatile cleaning capability while managing device complexity through a unified switching mechanism controlled by the programmable controller
2Productivity
If automated cleaning systems are used, then productivity is improved, but manufacturing precision deteriorates due to profile dimension variances
Solution Approach 1:
The patent incorporates sensors that detect the actual position and dimensions of window frame profiles during the cleaning process. This feedback information is fed to the programmable controller, which automatically adjusts the tool paths and cleaning parameters to compensate for profile dimension variances and misalignment, thereby maintaining manufacturing precision while achieving automated high-speed cleaning
Solution Approach 2:
The system uses a programmable controller that can dynamically adjust cleaning operations based on real-time profile detection. The controller modifies tool positions, speeds, and paths adaptively to accommodate variations in frame dimensions and alignment, resolving the contradiction between automated productivity and cleaning consistency
3Shape
If weld flash is removed aggressively, then appearance is improved, but material loss increases
Solution Approach 1:
The patent employs different types of cleaning tools (saw blades for aggressive removal, knives for precise trimming, end mills for detailed finishing, router bits for contour cleaning) to remove weld flash from different locations and orientations of the window frame. This localized tool selection resolves the contradiction by applying the appropriate level of material removal at each specific location, achieving good appearance while minimizing overall material loss
