Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining apparatuses have complex structures due to the need for a reverse inspection plate and transport mechanism, limiting productivity due to the time required to transport workpieces from the cutting table to the inspection plate.
Innovation Solution
A machining apparatus with a machining table featuring suction holes and through openings for machining and inspection, where the workpiece is suctioned and machined in place, allowing for in-situ imaging and inspection without the need for additional transport, and including a camera for capturing images of the machined workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a reverse inspection plate and transport mechanism are used to inspect packages, then inspection can be performed, but the structure becomes complicated and productivity decreases
Solution Approach 1:
The patent combines the inspection function with the existing machining table by integrating a camera system that captures images of workpieces during the suction and machining process. This eliminates the need for a separate reverse inspection plate, merging two functions (machining and inspection) into a single integrated system.
Solution Approach 2:
The patent extracts the inspection function from the mechanical transport system and implements it through an optical imaging system (camera). Instead of physically transporting workpieces to a separate inspection plate, the inspection capability is extracted and delivered through digital imaging during the machining process.
2Measurement precision
If packages are transported from cutting table to reverse holder plate for inspection, then inspection can be performed, but the time required for transport limits productivity improvement
Solution Approach 1:
The patent enables continuous inspection during the machining process by capturing images of workpieces while they are being suctioned and machined on the machining table. This eliminates idle transport time and ensures that inspection occurs continuously as part of the machining operation, not as a separate sequential step.
Solution Approach 2:
The inspection is performed preliminarily during the machining process itself, before the workpiece would otherwise need to be transported for separate inspection. The camera captures images during suction and machining, allowing inspection to occur in advance of any subsequent handling.
3Measurement precision
If a separate transport mechanism is used to move workpieces for inspection, then inspection can be performed, but the apparatus requires more components and becomes more complex
Solution Approach 1:
The machining table is given multiple functions: it serves as both the machining surface and the inspection platform. The suction holes and vacuum system serve dual purposes of holding workpieces during machining and positioning them for camera inspection, eliminating the need for dedicated inspection hardware.
Solution Approach 2:
The patent merges the inspection function into the existing machining table structure by integrating a camera system that operates during the suction and machining process. This combines multiple functions (machining, holding, and inspection) into a single integrated system, reducing the total number of components.
