Dual-Axis Flipper Positioning for Single-Camera Object Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection methods for objects on a transfer rail are costly due to the need for multiple camera devices and are inefficient in terms of space and time, especially when inspecting all surfaces of an object.
Innovation Solution
A flipper apparatus with Y-axis and X-axis flipper units and a Z-axis elevation unit, allowing for the rotation and positioning of objects at multiple angles for inspection using a single camera device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple camera devices are used to inspect top and side surfaces of objects on a transfer rail, then inspection coverage is improved, but apparatus cost increases substantially
Solution Approach 1:
A single camera device is made multi-functional by implementing a rotating mechanism that allows it to inspect multiple surfaces (top, side, front, rear) of objects. The camera rotates about the Y-axis to inspect different surfaces sequentially, replacing what would traditionally require multiple fixed camera devices positioned at different locations.
Solution Approach 2:
The camera device is transformed from a static inspection tool to a dynamic one by adding rotation capability. The camera can rotate about the Y-axis to change its inspection angle and orientation, enabling it to capture images of multiple surfaces that would otherwise require multiple fixed cameras positioned at different angular locations.
2Adaptability or versatility
If conventional turn-over apparatus is used to inspect all surfaces of objects, then inspection completeness is improved, but space efficiency decreases and inspection time increases
Solution Approach 1:
The single camera device performs multiple inspection functions (top surface, side surfaces, front surface, rear surface) that would traditionally require separate inspection stations or turn-over apparatus. By integrating rotation capability, one camera replaces what would otherwise require multiple cameras and complex turn-over mechanisms.
Solution Approach 2:
The inspection system adds rotational dimensionality to the camera's operation. Instead of moving objects through multiple fixed inspection stations in linear space, the camera rotates about the Y-axis to access different surfaces, effectively using angular rotation as an additional dimension for inspection coverage.
