Rotating Assembly Blade Attachment With Measured Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching blades to a rotating body in manufacturing rotating assemblies, such as turbine generators, are inefficient and require manual labor, leading to suboptimal work efficiency.
Innovation Solution
A manufacturing system comprising a stand, a measurement device, an attachment device, and a transfer device that automates the process of attaching blades to a rotating main body portion by measuring and positioning each blade accurately and efficiently, using a gantry-type orthogonal robot for transfer and a vertical articulated robot for attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to attach blades to a rotating body, then flexibility and adaptability are maintained, but work efficiency and productivity are reduced
Solution Approach 1:
The measurement device automatically measures the physical amount of each blade, and the attachment device automatically attaches blades to predetermined positions based on measurement results, enabling the system to serve itself without continuous manual intervention while maintaining precision
Solution Approach 2:
Manual mechanical attachment operations are replaced by an automated attachment device that uses measurement data to position and attach blades, substituting human labor with automated mechanical systems controlled by measured physical quantities
2Productivity
If automated attachment is implemented, then productivity and work efficiency are improved, but device complexity increases
Solution Approach 1:
The manufacturing system is divided into distinct functional modules: a measurement device for measuring blade physical amounts, a transfer device for moving blades, and an attachment device for attaching blades to predetermined positions. This segmentation allows each module to perform its function independently, simplifying the overall system architecture while maintaining high productivity
Solution Approach 2:
The attachment device is designed to universally handle multiple blades of different physical amounts by adjusting attachment positions based on measurement data, allowing a single device to perform multiple attachment operations without requiring specialized equipment for each blade type
3Manufacturing precision
If precise measurement and positioning are implemented, then manufacturing precision is improved, but measurement and device complexity increase
Solution Approach 1:
The measurement device measures the physical amount of each blade and provides feedback to the attachment device, which uses this information to determine the predetermined attachment position. This feedback loop ensures precise positioning without requiring overly complex measurement and positioning systems, as the system adapts to each blade's actual dimensions
