Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber processing, and in particular to an optical fiber hot-melt stretching device and method. Background Art

[0002] In modern optical communications, fiber-optic sensing, and fiber-optic lasers, optical fiber, with its advantages of low loss, high bandwidth, and strong anti-interference capabilities, has become a core medium for information transmission and energy conduction. During optical fiber processing, it is often necessary to cut the fiber to specific lengths according to the needs of different application scenarios. However, the density of raw optical fiber bundles is low, and direct cutting presents many problems.

[0003] At present, conventional optical fiber cutting methods mostly operate on the natural state of the optical fiber. Due to the loose distribution and low density of the internal optical fiber bundles, it is very easy to have bundle misalignment and uneven breakage during cutting, resulting in an uneven end face of the cut optical fiber, affecting the subsequent welding quality and optical transmission performance with connectors, couplers and other devices. At the same time, the loose bundle structure makes it difficult to ensure cutting accuracy, especially for the demand for high-precision, small-sized optical fiber products, which traditional cutting methods cannot meet. In order to improve the cutting effect, some technologies try to improve accuracy by adding auxiliary clamps or optimizing cutting tools, but such methods not only increase equipment costs and operational complexity, but also have limited improvement on the loose structural problems of the optical fiber bundle itself.

[0004] Furthermore, the continuous expansion of fiber optic applications, such as high-density fiber arrays and integrated optical devices, places higher demands on the consistency and adaptability of cut fiber. Original low-density fiber, after cutting, cannot directly meet the assembly requirements of these complex applications, often requiring additional finishing and adjustment steps, further reducing production efficiency and increasing processing costs.
