Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, and particularly relates to a beam tube and an optical fiber. Background Art

[0002] With the continuous progress of technology, as a new type of transmission medium, optical fibers have been widely used in various fields such as communication, medical treatment, industrial control, energy, and transportation. Among them, LDI optical fibers are used for energy transmission, with one end connected to a laser generator and the other end connected to a lens. During the energy transmission process, the optical fiber bundle is sleeved into beam tubes such as sleeves and collars for the transmission and connection of optical fibers. To ensure that the shaped and fixed optical fiber bundle can maintain its size and shape stable without disorder and avoid displacement at the energy output end of the existing LDI optical fiber, viscous fillers such as glue and rosin are often used to fill the beam tubes such as sleeves and collars containing the optical fiber bundle. However, this method is very inconvenient in the production process. On the one hand, it is necessary to fill viscous fillers into components such as sleeves and beam tubes, which increases the production steps and time consumption, and there may also be a situation where the filler overflows; on the other hand, it is necessary to cure the filler and wait for the filler to cure, which increases the production cost and production time; there is an urgent need for improvement.

[0023] The following will further describe the present utility model in detail with reference to the drawings.

[0024] This specific embodiment is only an interpretation of the present utility model and does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute to the creation as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.

[0025] This embodiment relates to a beam tube 100. Referring to Figures 1 - 3 , it includes: a surrounding wall 110 and an internal member 120. The surrounding wall 110 is in a tubular shape; the internal member 120 is disposed within the surrounding wall 110 to divide the interior of the surrounding wall 110 into a plurality of independent channels 130 for placing a single optical fiber 200. In existing optical fibers, most of them fix the optical fibers 200 in the beam tube 100 by injecting viscous fillers such as glue and adhesives. In this embodiment, by providing the internal member 120 within the surrounding wall 110, the internal space of the surrounding wall 110 is divided into independent channels 130 for placing a single optical fiber 200, so as to achieve the purpose of fixing and positioning the optical fiber 200, making the position of each optical fiber 200 in the beam tube 100 fixed. On the one hand, it avoids the displacement of the optical fiber 200 and the loosening of the optical fiber bundle caused by factors such as the aging of the viscous filler, temperature change, or mechanical vibration during the use of the optical fiber, ensuring good stability during the optical fiber energy transmission process; on the other hand, it is convenient to quickly locate the damaged optical fiber 200 when the optical fiber is damaged, saving the troubleshooting time. In this embodiment, specifically, the internal member 120 is centrally disposed within the surrounding wall 110, so that the channels 130 for placing the optical fibers 200 are also in the central position within the surrounding wall 110. Therefore, the optical fibers 200 are neatly centered, which can not only solve the problem of the irregularity of the optical fibers 200 in the beam tube 100, but also make the aperture of the optical fiber output end small, obtain a high-energy light output, and have good uniformity of the output laser energy. In some embodiments, the optical fibers 200 can be placed only in certain specific channels 130 according to requirements, thereby controlling the spacing of the optical fibers 200 in the beam tube 100 and realizing the control of the density of the optical fiber bundle in the beam tube 100.

[0026] Referring to Figures 1 - 3 , the cross-section of the channel 130 is circular, which is convenient for adapting to the shape of the optical fiber 200. Specifically, in this embodiment, the channel 130 is in a cylindrical shape to reduce the friction and wear generated between the optical fiber 200 and the inner wall of the channel 130 due to shape mismatch, improve the stability of the optical fiber 200 in the channel 130, and optimize the space utilization.

[0027] Further, the cross-sectional areas of the multiple channels 130 are the same. By restricting the cross-sections of the channels 130 to be the same, the diameters of the channels 130 are further restricted to be the same, so that the diameters of the inserted optical fiber filaments 200 are the same, ensuring that the inserted optical fiber filaments 200 are of the same type of optical fiber filaments 200 and ensuring the uniformity of the optical fiber filaments 200.

[0028] In addition, in this embodiment, the diameter of the channel 130 is slightly larger than the diameter of the optical fiber filament 200. Specifically, the diameter of the channel 130 is longer than the diameter of the optical fiber filament 200, and the length difference is less than 5%. This ensures that the optical fiber filament 200 can be inserted, but without leaving too much extra space, avoiding too much reserved space that may cause the optical fiber filament 200 to deviate too much in the channel 130.

[0029] Refer to Figures 1 - 3 , the beam tube 100 is symmetrically arranged. Specifically, the beam tube 100 can be axially symmetrically arranged or centrally symmetrically arranged.

[0030] In this embodiment, refer to Figures 1 - 3 , the enclosure wall 110 together with the internal components 120 is axially symmetrically arranged, so that the channels 130 are also axially symmetrically arranged with respect to each other. Furthermore, the positions where the optical fiber filaments 200 are placed are also axially symmetric, meeting the energy output requirements during the use of the optical fiber.

[0031] Refer to Figure 3 , the enclosure wall 110 together with the internal components 120 is centrally symmetrically arranged with respect to the center of the enclosure wall 110, so that the channels 130 are also centrally symmetrically arranged with respect to the center of the enclosure wall 110. Furthermore, the positions where the optical fiber filaments 200 are placed are centrally symmetrically arranged with respect to the center of the enclosure wall 110, meeting the energy output requirements during the use of the optical fiber. In some embodiments, the enclosure wall 110 together with the internal components 120 is centrally symmetrically arranged with respect to the center of the enclosure wall 110, and the channels 130 can also be centrally symmetrically arranged with respect to the channel 130 located at the center of the enclosure wall 110.

[0032] Refer to Figures 1 - 3 , the transverse cross-section of the enclosure wall 110 is polygonal, elliptical or circular to meet different docking requirements of the output end during the use of the optical fiber. In this embodiment, the transverse cross-section of the enclosure wall 110 is circular, and the beam tube 100 is cylindrical. In other embodiments, the transverse cross-section of the enclosure wall 110 can also be polygonal or elliptical.

[0033] In this embodiment, the material of the beam tube 100 is red copper. As a kind of copper with relatively high purity, red copper has good heat dissipation and plasticity. On the one hand, it can quickly dissipate heat, realizing the effective dissipation of heat and avoiding the over-high temperature inside the beam tube 100, which may affect the transmission performance of the optical fiber filaments 200. On the other hand, red copper has good plasticity and can adapt to different energy output docking requirements, facilitating processing into various shapes. In other embodiments, the material of the beam tube can also be other materials with good heat dissipation performance.

[0034] This embodiment also relates to an optical fiber. Referring to Figure 4 , it includes: the beam tube 100 and the optical fiber bundle as described above. The optical fiber bundle includes multiple optical fiber filaments 200 that are fixedly arranged and placed in the channel 130. This optical fiber bundle has the advantages of good uniformity of output laser light energy and a small output end aperture.

[0035] Furthermore, the optical fiber is a silica optical fiber. The silica optical fiber has the advantages of a large numerical aperture, a large core diameter of the optical fiber, high mechanical strength, and good bending performance.

[0036] The advantages of the present utility model are as follows: In the present utility model, the beam tube 100 in the optical fiber includes the surrounding wall 110 and the internal member 120. The internal member 120 divides the interior of the surrounding wall 110 into multiple independent channels 130 for placing one optical fiber filament 200, so that the position of each optical fiber filament 200 in the beam tube 100 is fixed, ensuring the precise positioning of the optical fiber filaments 200 in the beam tube 100, preventing the position deviation of the optical fiber filaments 200 due to external factors, ensuring the overall orderliness, uniformity, and good output energy uniformity of the optical fiber filaments 200, and playing a role in reducing the output end aperture of the optical fiber. In addition, the design of the independent channels 130 facilitates the precise positioning of the specific optical fiber filament 200 when the optical fiber is damaged subsequently, and also facilitates the replacement of the damaged optical fiber filament 200.

[0037] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
