A miniature bare optical fiber automatic reel system

Abstract

The defects that response falls behind, the adjustable range is narrow, transmission is not stable, arranging is not tidy, and bare optical fibers are prone to damage exist in a winding and unwindingmanner of a current domestic traditional optical fiber winding and unwinding system, the requirements for the small bare optical fiber diameter and high winding and unwinding speed response cannot bemet, the bare optical fiber needs to be kept on the same horizontal line with a winding inlet or at the angle required not to be in a great difference in the work process, the phenomena of bare optical fiber damage and direct fracture are likely to happen when the excessive tensioning state is encountered, the work efficiency is low, faults are likely to happen, manpower is needed for supervisionand intervention, and manpower and material resources are greatly wasted. The defects in the prior art are overcome, a mini bare optical fiber automatic reel system is provided, the tension can be monitored in real time, feedback is conducted for automatic adjustment of tension, the phenomena of fracture and damage of the bare optical fiber in the winding or unwinding process are effectively avoided, and the trouble of manual supervision and assisting is saved.

Description

technical field [0001] The invention relates to the field of automatic retracting and coating of optical fibers, and more particularly relates to an automatic reel system for miniature bare optical fibers. Background technique [0002] Optical fiber is a light transmission tool based on the principle of total reflection of light in fibers made of glass and plastic. Based on its advantages of large communication capacity, long relay distance, no electromagnetic interference, light weight and small size, it is used in Communication has been widely used. The fiber core in the optical fiber is usually a double-layer concentric cylinder with a small cross-sectional area made of quartz glass. It is brittle, easy to break, and has relatively low breaking strength and working limit tensile force. It is used in systems involving optical fiber retraction. During the application process, it is easy to be over-tensioned or loosened, which will affect the uniformity and integrity of the...

Problems solved by technology

The fiber core in the optical fiber is usually a double-layer concentric cylinder with a small cross-sectional area made of quartz glass. It is brittle, easy to break, and has relatively low breaking strength and working limit tensile force. It is used in systems involving optical fiber retraction. During the application process, it is easy to be over-tensioned or loosened, which will affect the uniformity and integrity of the bare optical fiber. The traditional process usually requires manual intervention to successfully complete the retraction and release of the optical fiber, which is a waste of manpower.

[0003] At present, the domestic traditional optical fiber retractable system has shortcomings such as response lag, small adjustable range, unstable transmission, irregular arrangement, and easy damage to bare optical fibers, which cannot meet the requirements of small diameter of bare optical fiber and fast response of retractable speed. requirements, and during the working process, the bare fiber should always be kept on the same horizontal line as the winding inlet or the angle should not be too different, because the bare fiber is prone to slipping out of the winding when it encounters excessive relaxation during the retracting process The phenomenon of uneven track and winding; when encountering excessive tension, it is easy to damage and directly break the bare optical fiber, which not only has low work efficiency and is prone to failure, but also requires human supervision and intervention, which is extremely wasteful of manpower and material resources
