Optical Fiber Winding with Movable Roller and Slit Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Winding devices struggle with wire hitting during high-speed winding, causing damage to optical fibers or electric wires due to the cleaved terminal wire bouncing back and hitting the wound-up winding body, leading to decreased yield and fiber breakage.
Innovation Solution
A winding device with a bobbin, cover, and roller configuration that allows the roller to move relative to the bobbin or the cover's slit to adjust the path of the striatum, preventing contact between the cover and the wound-up striatum, using mechanisms to calculate the bobbin winding body diameter and adjust the roller's position based on the winding length or weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is attached to the outer circumference of a bobbin to prevent wire hitting, then the striatum is protected from damage, but the cover contacts the wound-up striatum when the bobbin winding body diameter becomes large, causing friction and potential damage
Solution Approach 1:
The invention makes the cover movable relative to the bobbin in the radial direction. As the bobbin winding body diameter increases during winding, the cover automatically moves outward to maintain a constant gap from the wound-up striatum, preventing contact and friction damage while continuing to protect against wire hitting
Solution Approach 2:
The system uses a sensor to detect the bobbin winding body diameter and feeds this information back to control the cover's radial position. The cover position is dynamically adjusted based on real-time measurements of the winding diameter, ensuring optimal protection without contact
2Device complexity
If the roller position is fixed during winding, then the device structure is simple, but the roller cannot adapt to changing bobbin winding body diameter, causing the striatum to contact the cover and resulting in wire hitting
Solution Approach 1:
The roller is made movable in the radial direction with its position dynamically adjusted according to the bobbin winding body diameter. This dynamic positioning ensures the roller maintains proper contact with the striatum throughout the winding process, guiding it smoothly onto the bobbin without causing wire hitting
Solution Approach 2:
A sensor detects the bobbin winding body diameter and provides feedback to a controller, which automatically adjusts the roller's radial position. This closed-loop control system adapts the roller position to match the changing winding diameter, preventing wire hitting while keeping the control mechanism relatively simple

AI summary
This winding device includes: a bobbin for winding an optical fiber, the bobbin being a striated body; a cover that covers the outer periphery of the bobbin, the cover having provided thereto a slit that is parallel to the axial direction of the bobbin, and the optical fiber being inserted through the slit; and a roller for directly guiding the optical fiber to the bobbin. In accordance with the bobbin winding barrel diameter of the optical fiber on the bobbin, the bobbin and the roller are caused to move relatively, or the position of the slit in the cover is caused to move in the circumferential direction.
