Description

Technical Field

[0001] This utility model relates to the field of optical fiber bundling technology, specifically a high-temperature melting device for optical fiber bundlers. Background Technology

[0002] An optical fiber combiner is an optical fiber device fabricated based on a fused taper optical fiber bundle. The high-temperature melting device is an important component of the optical fiber combiner, used to melt the optical fibers at high temperatures, thereby enabling the optical fibers to fuse together.

[0003] Currently, high-temperature melting devices in practical use generate instantaneous high temperatures through two electric heating rods to melt the optical fiber. During the high-temperature heating process, inert gas is used for protection, which helps improve the quality of the melting process and prevent oxidation. However, current inert gas is only directed unidirectionally to the melting point, resulting in poor coverage and affecting the melting quality. Therefore, we propose a high-temperature melting device for optical fiber combiners. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature melting device for optical fiber combiners, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature melting device for an optical fiber combiner, comprising a base, wherein limit blocks are fixedly installed on both sides of the top of the base, and limit grooves are formed on the top of the limit blocks;

[0006] Support plates are fixedly installed on both sides of the top center of the base. An electric heating rod is fixedly installed through the outer wall of the support plate. A wire is fixedly connected to the tail end of the electric heating rod. An air distribution component is connected to the electric heating rod. The air distribution component is used to distribute air evenly.

[0007] By adopting the above technical solution, the optical fibers to be fused together are first placed in the limiting grooves on the top of the limiting blocks on both sides, and the ends are aligned. Then, an electric heating rod is used to heat the fibers, thereby fusion-joining the optical fibers on both sides. During the fusion-joining process, an inert gas is uniformly discharged to the fusion area through the gas distribution component, thereby protecting the fusion area and helping to avoid oxidation, thus improving the quality of fusion-joining.

[0008] In a preferred embodiment of this utility model, the gas distribution assembly includes an annular shell, on which an electric heating rod is rotatably mounted. A plurality of evenly distributed holes are provided on one side wall of the annular shell. A fixing pipe is fixedly connected to the upper back side of the annular shell. An inert gas pipe is fixedly connected to the outer end of the fixing pipe. A control valve is fixedly installed at the connection between the inert gas pipe and the fixing pipe.

[0009] By adopting the above technical solution, during heating and melting, inert gas is introduced into the fixed tube through the inert gas tube, thereby entering the inner cavity of the annular shell and being discharged through the holes. This allows the discharged gas to form a coating ring, which can coat the molten area, thus improving the coating effect and consequently improving the quality of optical fiber melting.

[0010] In a preferred embodiment of this utility model, a servo motor is fixedly installed on the upper back side of the support plate. The transmission shaft of the servo motor movably passes through the support plate and is fixedly connected to a rotating plate. Limiting rods are fixed on both sides of the surface of the rotating plate. Limiting plates are provided at the outer ends of the two limiting rods. The limiting plates and limiting rods are fixedly connected. The two limiting rods are located on both sides of the fixed tube.

[0011] By adopting the above technical solution, the servo motor drives the rotating plate to reciprocate, which in turn drives the fixed tube to reciprocate, thereby driving the annular shell to rotate. This helps to further improve the uniformity of the coating ring formed after the gas is discharged, and thus further improves the coating effect.

[0012] In a preferred embodiment of this utility model, the outer wall of the limiting rod is movably fitted with a rotating tube.

[0013] By adopting the above technical solution, the rotating tube is designed to rotate, which helps to reduce wear when driving the fixed tube to move.

[0014] In a preferred embodiment of this utility model, a cold air duct is fixedly connected to the other side of the fixed pipe, and a control valve is fixedly installed at the connection between the cold air duct and the fixed pipe.

[0015] By adopting the above technical solution, by closing the control valve on the inert gas pipe and opening the control valve on the cold air pipe, the cooling air can be directed along the holes to the molten area, which is conducive to cooling the molten area during the coating process, thereby improving the cooling effect and cooling efficiency.

[0016] In a preferred embodiment of this utility model, mounting holes are provided at the four corners of the top of the base.

[0017] By adopting the above technical solution, the installation holes facilitate the installation and fixation of the entire device.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The present application provides a high-temperature melting device for an optical fiber combiner. By providing an annular shell, inert gas is introduced into the inner cavity of the annular shell and then discharged through multiple holes on one side of the annular shell. This discharge forms a coating ring, which can coat the molten area, thereby improving the coating effect and thus improving the quality of optical fiber melting.

[0020] The drive component can drive the fixed tube to bend back and forth to both sides, thereby causing the annular shell to rotate back and forth, which helps to further improve the uniformity of the coating ring formed after the gas is discharged, and thus helps to further improve the coating effect.

[0021] By closing the control valve on the inert gas pipe and opening the control valve on the cold air pipe, the cooling air can be directed along the holes to the molten area, which is beneficial for cooling the molten area during the coating process, thereby improving the cooling effect and efficiency.

[0030] Please see Figure 1-3 This utility model provides a technical solution: a high-temperature melting device for an optical fiber combiner, including a base 1, with limiting blocks 12 fixedly installed on both sides of the top of the base 1, and limiting grooves formed on the top of the limiting blocks 12.

[0031] Support plates 2 are fixedly installed on both sides of the top center of the base 1. An electric heating rod 21 is fixedly installed through the outer wall of the support plate 2. A wire 22 is fixedly connected to the tail end of the electric heating rod 21. An air distribution component is connected to the electric heating rod 21. The air distribution component is used to distribute air evenly.

[0032] It should be understood that in actual use, the optical fibers that need to be fused together are first placed in the limiting grooves on the top of the limiting blocks 12 on both sides, and the ends are aligned. Then, the electric heating rod 21 is used to heat the fibers, so that the optical fibers on both sides are fused together. During the fusion process, inert gas is uniformly discharged to the fusion area through the gas distribution component, thereby protecting the fusion area and helping to avoid oxidation, which in turn helps to improve the quality of fusion.

[0033] Furthermore, mounting holes 11 are provided at the four corners of the top of the base 1. The mounting holes 11 facilitate the installation and fixation of the entire device.

[0034] like Figure 1 and 2 As shown in Figure 3; the gas distribution assembly includes an annular shell 3, the outer wall of which is rotatably fitted with an electric heating rod 21, a plurality of evenly distributed holes are opened on one side wall of the annular shell 3, a fixed pipe 31 is fixedly connected to the upper back side of the annular shell 3, an inert gas pipe 32 is fixedly connected to the outer end of the fixed pipe 31, and a control valve is fixedly installed at the connection between the inert gas pipe 32 and the fixed pipe 31.

[0035] It should be understood that during heating and melting, inert gas is introduced into the fixed tube 31 through the inert gas tube 32, thereby entering the inner cavity of the annular shell 3 and being discharged through the holes. This allows the discharged gas to form a coating ring, which can coat the molten area, thus improving the coating effect and consequently improving the quality of optical fiber melting.

[0036] Furthermore, a servo motor 34 is fixedly installed on the upper back side of the support plate 2. The drive shaft of the servo motor 34 movably passes through the support plate 2 and is fixedly connected to a rotating plate 35. Limiting rods 36 are fixed on both sides of the surface of the rotating plate 35. Limiting plates 37 are provided at the outer ends of the two limiting rods 36. The limiting plates 37 and the limiting rods 36 are fixedly connected. The two limiting rods 36 are located on both sides of the fixed tube 31.

[0037] It should be understood that by driving the rotating plate 35 to reciprocate through the servo motor 34, the fixed tube 31 can be driven to reciprocate, thereby driving the annular shell 3 to rotate. This is beneficial to further improve the uniformity of the coating ring formed after the gas is discharged, and thus further improves the coating effect.

[0038] Furthermore, the outer wall of the limiting rod 36 is movably fitted with a rotating tube 38. The rotating tube 38 is designed to rotate, which helps to reduce wear when the fixed tube 31 is moved.

[0039] like Figure 1 and 2 As shown; a cold air duct 33 is fixedly connected to the other side of the fixed pipe 31, and a control valve is fixedly installed at the connection between the cold air duct 33 and the fixed pipe 31;

[0040] It should be understood that by closing the control valve on the inert gas pipe 32 and opening the control valve on the cold air pipe 33, the cooling air can be directed along the holes to the molten area, which is beneficial for cooling the molten area during the coating process, thereby improving the cooling effect and cooling efficiency.
