Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to a high-performance optical fiber coated with glass fiber. Background Art

[0002] Optical fibers can be categorized by their application as communication fibers and non-communication fibers. Communication fibers utilize the ability of optical fibers to transmit light signals of varying wavelengths to achieve communication. Non-communication fibers, however, are collectively referred to as non-communication fibers. Based on their light transmission properties, non-communication fibers can be used in a variety of applications, such as medical lighting and diagnosis, laser transmission, UV curing, sensing, inspection, military sights, criminal investigation imaging, and decorative lighting. The fibers most relevant to everyday life are used in decorative lighting applications, such as colorful advertising lights, decorative starry sky ceilings, and night fishing buoys. Fibers used for decorative lighting typically have larger diameters, ranging from 0.1 mm to several millimeters, such as PMMA and PS fibers.

[0003] Existing optical fibers used in decorative lighting are easily damaged, leading to light transmission failure. They are typically coated with a protective sleeve. Fiberglass sleeves are an excellent protective material, being lightweight, strong, and durable. The existing processing method involves cutting the optical fiber and fiberglass sleeve separately, then manually threading the sleeve. After threading, uneven ends require a second cut, followed by gluing and sealing. This process is highly manual and inefficient. A more serious problem is that this model, requiring manual control and confirmation, is affected by the operating environment and the mental state of the operator, resulting in a certain rate of error, leading to warping, damage, and scrapping of the product, impacting product quality. Furthermore, manual threading requires a gap in the sleeve aperture, further limiting the aperture and weight. Summary of the Invention

Compared with the traditional operation method, the operation efficiency can be increased by more than 5 times; it can also improve the product performance and quality, making the durability, thinness and weight of the product significantly improved and enhanced.

Description of the Drawings

[0015] Figure 1 is a perspective view of the present utility model.

[0016] The reference numerals are: optical fiber body 1, glass fiber coating layer 2, micro-engraved light-transmitting area 3, coloring layer 4. Detailed Embodiments

[0017] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the attached Figure 1 drawings. The content mentioned in the embodiments does not limit the present utility model.

[0018] See Figure 1, A high-performance optical fiber coated with glass fiber, comprising an optical fiber body 1 and a glass fiber coating layer 2 integrally formed on the outer surface of the optical fiber body 1. The two ends of the optical fiber body 1 are flush with the two ends of the glass fiber coating layer 2. A micro-engraved light-transmitting area 3 is engraved on the outer surface of the optical fiber body 1, and a coloring layer 4 is coated on the surface of the micro-engraved light-transmitting area 3.

[0019] In the high-performance optical fiber coated with glass fiber of the present utility model, the glass fiber and the optical fiber are integrally formed by coating, without segmental cutting and manual casing, avoiding additional material loss and processing costs; through the integrated forming and automated production of the whole processes of forming, micro-engraving, cutting and coloring, the production operation efficiency is greatly improved. Compared with the traditional operation method, the operation efficiency can be increased by more than 5 times; it can also improve the product performance and quality, making the durability, thinness and weight of the product significantly improved and enhanced.

[0020] In this embodiment, the glass fiber coating layer 2 is a polyurethane resin layer dispersed with glass fibers. Specifically, the method for integrally forming the glass fiber coating layer 2 is as follows: insert the optical fiber body 1 into the material placement hole of the coating mold, and then fill the high-transparent polyurethane resin with a curing agent, an anti-ultraviolet agent and glass fibers mixed, and inject it into the mold cavity of the coating mold from the injection hole of the coating mold, and heat and cure it together with the inserted optical fiber body 1. In the prior art, it is necessary to manually insert the optical fiber into the hollow tube, which is time-consuming, the quality is unstable, and the hollow tube is easily damaged, and the weather resistance and mechanical properties of the optical fiber cannot be protected. However, in the present utility model, the optical fiber will not be damaged after the glass fiber coating layer and the optical fiber are integrally formed, and the optical fiber can be better protected.

[0021] In this embodiment, the glass fiber is an alkali-free glass fiber with a single filament diameter of 5-15 μm. The alkali-free glass fiber has the advantages of high tensile strength, good dimensional stability, good heat resistance, non-combustibility, good light transmittance and good insulation.

[0022] In this embodiment, the light transmittance of the polyurethane resin layer is 70%-90%. By using a high-transparent polyurethane resin, it is convenient for the light emitted by the optical fiber to pass through.

[0023] In this embodiment, the engraving depth of the micro-engraved light-transmitting area 3 is 10 - 500 μm. Specifically, when the diameter of the optical fiber is a fraction of a millimeter, the engraving depth of the micro-engraved light-transmitting area 3 can be 10 μm, 25 μm, 50 μm, or 75 μm; when the diameter of the optical fiber is several millimeters, the engraving depth of the micro-engraved light-transmitting area 3 can be 100 μm, 200 μm, 300 μm, 400 μm, or 500 μm. The engraving depth of the micro-engraved light-transmitting area 3 can be reasonably set according to the diameter of the optical fiber. By engraving on the side of the optical fiber body 1, the side of the optical fiber can be made to transmit light at the engraved position. It should be noted that communication optical fibers cannot be engraved, as it will affect the signal transmission inside the optical fiber; however, the optical fiber used in the present utility model is a non-communication optical fiber for lighting and decoration, so it is necessary to engrave on the side of the optical fiber body 1 to make the side of the optical fiber emit light.

[0024] In this embodiment, the thickness of the coloring layer 4 is 10 - 250 μm. Specifically, when the diameter of the optical fiber is a fraction of a millimeter, the thickness of the coloring layer 4 can be 10 μm, 25 μm, 50 μm, or 75 μm; when the diameter of the optical fiber is several millimeters, the thickness of the coloring layer 4 can be 100 μm, 150 μm, 200 μm, or 250 μm. The thickness of the coloring layer 4 can be reasonably set according to the diameter of the optical fiber. By using the coloring layer 4, the light transmitted from the side of the optical fiber can present various colors. Optionally, the thickness of the coloring layer 4 can be the same as the engraving depth of the micro-engraved light-transmitting area 3, so that the coloring layer 4 completely fills the engraved micro-engraved light-transmitting area 3; in other embodiments, the thickness of the coloring layer 4 can also be less than the engraving depth of the micro-engraved light-transmitting area 3.

[0025] In this embodiment, both ends of the glass fiber coating layer 2 are coated with a sealing glue layer. Glue application treatment at both ends of the glass fiber coating layer 2 can play a sealing role.

[0026] In this embodiment, the sealing glue layer is epoxy resin glue. By using epoxy resin glue, it has good sealing performance and weather resistance.

[0027] The above embodiments are the preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the present utility model is within the protection scope of the present utility model.
