Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable detection methods are inadequate for on-line detection of long cables due to space constraints and inefficiencies in rotating camera devices within conventional cable feeding systems, making it difficult to inspect the entire surface of cables effectively.
Innovation Solution
A cable detection apparatus featuring a rotatable camera device and optical element that synchronously rotate with a cable support system, allowing for efficient image capture and transmission of the cable's surface defects, even in limited spaces, using a vision system with a camera, optical element, and driving mechanisms to rotate and position the camera for comprehensive inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera device is rotated to detect long cables, then the detection capability is improved, but the space requirement increases which conflicts with limited cable feeding system space
Solution Approach 1:
The optical element is positioned within the rotating platform structure, nesting the optical path components inside the rotation mechanism. This allows the camera system to rotate and detect long cables while maintaining a compact footprint that fits within limited cable feeding system space.
Solution Approach 2:
The optical element changes the optical path direction by 90 degrees, redirecting light from a horizontal path to a vertical path (or vice versa). This dimensional change in light transmission allows the camera to capture images of long cables extending in one direction while the camera itself rotates in a perpendicular plane, solving the space constraint problem.
2Device complexity
If a fixed camera device is used for cable detection, then the device complexity is reduced, but the detection efficiency for moving cables deteriorates
Solution Approach 1:
The camera device is mounted on a rotating platform that can rotate to follow the movement of cables during feeding operations. This dynamic capability allows the camera to maintain proper positioning relative to moving cables, significantly improving detection efficiency while the rotation mechanism remains relatively simple and integrated into the existing cable feeding system.
3Area of moving object
If the camera device rotates to capture cable images, then the coverage area is improved, but the synchronization with cable movement becomes more difficult
Solution Approach 1:
The system employs feedback mechanisms where the rotation of the camera platform is synchronized with cable feeding operations. The optical element's 90-degree path change works in conjunction with the rotation to ensure that images are captured at the correct positions along the cable, maintaining proper synchronization between camera movement and cable movement through coordinated control.

AI summary
A cable detection apparatus includes a cable support and a vision system. The vision system has a camera device rotatable about an axis parallel to an axial direction of a cable to be detected, so as to capture an image of the cable, and an optical element rotated synchronously with the camera device. The optical element transmits the image of the cable to the camera device by changing an optical path of the image.
