Description

Technical Field

[0001] This utility model relates to the field of optical fiber manufacturing technology, and in particular to a thermal negative pressure cleaning device. Background Technology

[0002] When fabricating an optical fiber combiner, multiple optical fibers need to be inserted into a glass tube that has been thinned in the middle. Then, the fibers and the glass tube are tapered together to combine them into a single fiber. The standard outer diameter of the glass tube before thinning is 1.2 mm, the common wall thickness is 0.12 to 0.14 mm, and the common diameter of a single optical fiber is 0.25 to 1 mm. However, after the glass tube is thinned in the middle, it is difficult to insert multiple optical fibers. Alcohol, acting as a lubricant, needs to be injected into the glass tube first to reduce insertion resistance and facilitate the insertion of multiple optical fibers.

[0003] After inserting multiple optical fibers into a glass tube, the alcohol in the glass tube is difficult to evaporate quickly and naturally, resulting in low production efficiency. If a negative pressure oven with existing technology is used, the entire tray of optical fibers needs to be placed in the oven, wasting space and energy. If a special tooling is used to isolate the entire tray of optical fibers at the end from the oven, the tooling structure is complex and also occupies a large space. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient and energy-saving thermal negative pressure cleaning device.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A thermal negative pressure cleaning device includes a workbench. Along the length of the device, a front support plate is mounted on the front side of the workbench, and a front positioning tray for positioning optical fibers is mounted on top of the front support plate. Along the length of the device, a rear support plate is mounted on the rear side of the workbench, and a frame extending towards the rear of the workbench is mounted on top of the rear support plate. A rear positioning tray for positioning a glass tube is located on the frame, directly opposite the front positioning tray. A heating module for heating the inside of the glass tube is positioned above the workbench between the front and rear positioning trays. A negative pressure suction mechanism for providing negative pressure to the glass tube is provided on the frame.

[0007] Therefore, by operating the heating module, the inside of the glass tube is heated, creating heated air both inside and outside the tube. This accelerates the evaporation of alcohol within the tube. The negative pressure suction mechanism draws air in through the fiber optic port, creating a high-speed heated airflow within the tube. This process not only speeds up the evaporation and drying of alcohol throughout the tube but also flushes out impurities, removing them and cleaning the inside of the tube. This dual benefit is achieved by focusing heating only on the glass tube area, rather than the front and rear support plates. This concentrated heating reduces the heating area, minimizes heat loss, improves thermal efficiency, and results in rapid heating and energy savings.

[0008] Furthermore, the heating module includes an electric heating plate and a heat-conducting plate. The electric heating plate is installed above the worktable and between the front support plate and the rear support plate. The heat-conducting plate is installed on the electric heating plate and has a heating groove for the glass tube to be inserted.

[0009] The electric heating plate generates heat and transfers it to the heat-conducting plate. When the glass tube is placed in the heating tank, the heated heat-conducting plate can heat the outside of the glass tube, which helps to heat the glass tube quickly and facilitates the generation of hot airflow.

[0010] Furthermore, there are air gaps between both ends of the electric heating plate and the front support plate and the rear support plate, and there are air gaps between both ends of the heat-conducting plate and the front positioning plate and the rear positioning plate.

[0011] The electric heating plate is designed separately from the front and rear support plates, and the heat-conducting plate is designed separately from the front and rear positioning plates. This reduces the volume of unnecessary heat-conducting components, prevents heat from being quickly transferred to other parts, and ensures that the heat generated by the electric heating plate can be more concentratedly transferred to the heat-conducting plate for precise heating of the glass tube, making heating more energy-efficient and effective.

[0012] Furthermore, the negative pressure suction mechanism includes a mounting frame, a suction tube, and an adapter. The suction tube is mounted on the frame via the mounting frame. The front end of the suction tube extends to near the rear positioning plate and is equipped with an adapter. The adapter can match and connect with the glass tube port. The tail end of the suction tube is connected to a vacuum pump, which serves as a negative pressure source. An adjusting valve is installed on the suction tube.

[0013] After the glass tube is connected to the adapter, a vacuum pump generates negative pressure, which draws out the alcohol and air from the glass tube, thus creating a stable airflow for cleaning and drying inside the glass tube.

[0014] Furthermore, the front positioning plate has a positioning groove A for inserting and positioning optical fibers, and the rear positioning plate has a positioning groove B for inserting and positioning glass tubes.

[0015] The optical fiber is positioned by placing it into positioning slot A, and the glass tube is positioned by placing it into positioning slot B.

[0016] Furthermore, a temperature controller is provided on the front side of the workbench, and the electric heating plate is controlled by the temperature controller.

[0017] The start and stop of heating and the heating temperature of the electric heating plate can be adjusted by turning the knob on the temperature controller.

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

[0019] 1. This utility model heats the inside of a glass tube through a heating module, creating heated air both inside and outside the glass tube to accelerate the evaporation of alcohol. A negative pressure suction mechanism then draws air in through the fiber optic port, creating a high-speed heated airflow within the tube. This process accelerates the evaporation and drying of alcohol throughout the glass tube and also flushes out impurities, drawing them to the outside and achieving thorough cleaning – a dual benefit.

[0020] 2. This utility model features a separate design for the electric heating plate, the front support plate, and the rear support plate, as well as a separate design for the heat-conducting plate, the front positioning plate, and the rear positioning plate. This reduces the volume of unnecessary heat-conducting components, prevents excessive heat transfer to other parts, and ensures that the heat generated by the electric heating plate can be more concentratedly transferred to the heat-conducting plate for precise heating of the glass tube. This makes heating more energy-efficient and effective. The overall structure is reasonable, the size is small, and the practicality is high. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a thermal negative pressure cleaning device, including a workbench 01. Along the length 100 of the thermal negative pressure cleaning device, a front support plate 1 is installed on the front side of the workbench 01, and a front positioning tray 5 for positioning optical fibers is installed on the top of the front support plate 1. Along the length 100 of the thermal negative pressure cleaning device, a rear support plate 3 is installed on the rear side of the workbench 01, and a frame 4 extending towards the rear side of the workbench 01 is installed above the rear support plate 3. A rear positioning tray 6 for positioning a glass tube 10 is provided on the frame 4 directly opposite the front positioning tray 5. A heating module 2 for heating the inside of the glass tube 10 is provided above the workbench 01 between the front positioning tray 5 and the rear positioning tray 6. A negative pressure suction mechanism 7 for providing a negative pressure suction effect is provided on the frame 4.

[0027] After inserting multiple optical fibers into the glass tube 10 using alcohol as a lubricant, the inside of the glass tube 10 is dried and cleaned using this thermo-press cleaning device. The glass tube 10 and some of the optical fibers are placed on the device, ensuring the optical fibers are positioned on the front positioning plate 5 and the glass tube 10 is positioned on the rear positioning plate 6 for effective positioning. The port of the glass tube 10 without inserted optical fibers is connected to the negative pressure suction mechanism 7, while ensuring the port of the glass tube 10 with inserted optical fibers is at the heating module 2. The heating module 2 then heats the inside of the glass tube 10. Heat is generated both inside and outside the glass tube 10 to create heated air, accelerating the evaporation of alcohol inside the glass tube 10. The negative pressure suction mechanism 7 creates a negative pressure suction effect, which draws air in from the port 11 where the optical fiber is inserted into the glass tube 10, creating a high-speed airflow inside the glass tube 10. On the one hand, the heated airflow inside the glass tube 10 accelerates the evaporation and drying of alcohol throughout the glass tube 10. On the other hand, it can flush out dirt inside the glass tube 10, drawing the dirt to the outside of the glass tube 10, thus cleaning the inside of the glass tube 10 in one fell swoop.

[0028] Specifically, the heating module 2 includes an electric heating plate 21 and a heat-conducting plate 22. The electric heating plate 21 is installed above the worktable 01 and located between the front support plate 1 and the rear support plate 3. The heat-conducting plate 22 is installed on the electric heating plate 21. The heat-conducting plate 22 is provided with a heating groove 221 for the glass tube 10 to be placed into. The electric heating plate 21 generates heat and transfers the heat to the heat-conducting plate 22. When the glass tube 10 is placed in the heating groove 221, the heated heat-conducting plate 22 can heat the outside of the glass tube 10, which helps to generate a heating airflow.

[0029] In addition, there are air gaps between both ends of the electric heating plate 21 and the front support plate 1 and the rear support plate 3, and there are air gaps between both ends of the heat-conducting plate 22 and the front positioning support plate 5 and the rear positioning support plate 6. The electric heating plate 21 is designed separately from the front support plate 1 and the rear support plate 3, and the heat-conducting plate 22 is designed separately from the front positioning support plate 5 and the rear positioning support plate 6. This reduces the volume of unnecessary heat-conducting components, avoids excessive heat transfer to other parts, and ensures that the heat generated by the electric heating plate 21 can be more concentratedly transferred to the heat-conducting plate 22 to accurately heat the glass tube 10, making the heating more energy-efficient and effective.

[0030] Specifically, the negative pressure suction mechanism 7 includes a mounting frame 71, a suction pipe 72, and an adapter 73. The suction pipe 72 is mounted on the stand 4 via the mounting frame 71. The front end of the suction pipe 72 extends to near the rear positioning plate 6 and is fitted with an adapter 73. The adapter 73 can be matched and connected to the port 11 of the glass tube 10. The tail end of the suction pipe 72 is connected to a vacuum pump (not shown in the figure) that serves as a negative pressure source. After the end 12 of the glass tube 10 is connected to the adapter 73, the vacuum pump generates negative pressure, which can draw out the air inside the glass tube 10, thereby forming a stable airflow for cleaning and drying inside the glass tube 10. In addition, an adjusting valve 721 is also installed on the suction pipe 72, which allows for easy control of the magnitude and start / stop of the negative pressure airflow.

[0031] Specifically, the front positioning plate 5 has a positioning groove A51 for the optical fiber to be inserted and positioned. The optical fiber is positioned by inserting it into the positioning groove A51. The rear positioning plate 6 has a positioning groove B61 for the glass tube 10 to be inserted and positioned. The glass tube 10 is positioned by inserting it into the positioning groove B61.

[0032] Specifically, a temperature controller 02 is provided on the front side of the workbench 01. The electric heating plate 21 is controlled by the temperature controller 02. By turning the knob on the temperature controller 02, the heating start and stop and the heating temperature of the electric heating plate 21 can be adjusted. The specific control and adjustment principle adopts the existing technology and will not be described in detail in this application.

[0033] Preferably, along the width direction 200 of the thermal negative pressure cleaning device, the electric heating plate 21 has multiple heating grooves 221 arrayed on it, the support plate 1 is equipped with multiple front positioning trays 5 corresponding to the heating grooves 221, and the stand 4 is equipped with multiple positioning trays 6 corresponding to the heating grooves 221 and a negative pressure suction mechanism 7. This facilitates efficient cleaning of multiple glass tubes 10.

[0034] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
