Existing methods face challenges in achieving high precision when mounting components to frame members, such as those in aircraft, using robots alone, as they struggle to maintain the required precision of ±0.5 mm over lengths of 10 to 20 meters.
Innovation Solution
A component mounting system that incorporates a machining apparatus, a positioning unit, a robot, and a detector system with a camera and sensor to adjust the component's position and tilt relative to the machining axis, allowing for precise alignment and fastening using a fastener like a rivet, which includes multiple detectors for comprehensive positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a robot is used to position components on frame members, then automation is improved, but positioning precision deteriorates
Solution Approach 1:
The patent introduces an assembling jig as an intermediary device between the robot and the frame member. The jig includes positioning blocks and contour bars that provide precise mechanical positioning references, enabling the robot to achieve high positioning precision through the mediator rather than direct positioning.
Solution Approach 2:
The patent replaces manual positioning operations with an automated robot system that uses sensors and vision systems to detect component positions and adjusts its positioning accordingly, substituting mechanical human操作 with an automated control system.
2Manufacturing precision
If an assembling jig is used to achieve high positioning precision, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The assembling jig is divided into multiple functional modules including positioning blocks for precise location, contour bars for surface positioning, and fastening mechanisms. This segmentation allows each module to perform its specific function independently, making the complex system more manageable and maintainable.
3Manufacturing precision
If manual positioning methods are used, then positioning precision is improved, but productivity decreases
Solution Approach 1:
The system incorporates sensors and vision systems that automatically detect component positions and provide feedback to the robot control system, enabling the system to self-correct positioning errors without manual intervention, thus maintaining high precision while improving productivity.
