Description

Technical Field

[0001] This utility model relates to the field of optical fiber etching device technology, specifically a high-safety optical fiber etching device. Background Technology

[0002] Currently, chemical etching is generally used to control the diameter of optical fibers for the subsequent fabrication of passive optical fiber devices. However, chemical etching of optical fibers has poor reproducibility, long etching time, and is not easy to operate. The surface of the etched optical fiber still has a certain degree of roughness, which directly affects its interface reflection characteristics. Existing optical fiber etching machines have some shortcomings in use. In order to meet market needs, a high-safety optical fiber etching device is required.

[0003] Most existing etching devices can only etch optical fibers from one side, such as fixing the fiber vertically in a plastic tube for etching, or placing one end of the fiber horizontally into the etching device. This etching method cannot meet the actual needs of etching a section of fiber in some situations. Moreover, the sealing and leakage prevention effect of existing etching devices is not good enough during use. This means that the fiber optic clamp and cover cannot be sealed during use, which can easily lead to the hydrofluoric acid gas inside the fiber optic clamp harming the health of workers. In addition, the overall safety of existing etching devices is not high enough during use, which reduces the safety of using the fiber optic etching device and greatly reduces the degree of automation during use.

[0007] Preferably, a first fluoropolymer-lined centrifugal pump is installed inside the holding tank on the surface of the recycling tank. The input end of the first fluoropolymer-lined centrifugal pump is electrically connected to the output end of the controller.

The input end of the first water pump passes through the container and the clean water tank in sequence and extends into the interior of the clean water tank. The output end of the first water pump passes through the container and the optical fiber clamp seat in sequence and extends into the interior of the corrosion tank.

[0009] Preferably, a second water pump is installed inside the container on the surface of the sewage tank. The input end of the second water pump is electrically connected to the output end of the controller. The input end of the second water pump passes through the container and the optical fiber clamp seat in sequence and extends into the interior of the corrosion tank. The output end of the second water pump passes through the container and the sewage tank in sequence and extends into the interior of the sewage tank.

[0010] Preferably, a fixing pipe is installed on the surface of the top position of the hydrofluoric acid solution tank, the bottom end of the fixing pipe penetrates the hydrofluoric acid solution tank and extends into the interior of the hydrofluoric acid solution tank, and an inlet pipe is installed on the surface of the fixing pipe by screws, the inlet pipe being connected to the interior of the fixing pipe; a water inlet pipe is installed on the surface of the top position of the clean water tank, and an installation pipe is installed on the surface of the water inlet pipe by screws, the installation pipe being connected to the interior of the water inlet pipe, the bottom end of the water inlet pipe penetrating the clean water tank and extending into the interior of the clean water tank.

[0014] 1. By incorporating a sealing and leak-proof mechanism, the cover automatically engages with the positioning block inside the fiber optic clamp holder. The cover then moves the first rubber pad to contact the surface of the second rubber pad. The combined action of the first and second rubber pads seals the fiber optic clamp holder and the cover. When the cover moves to the surface of the fiber optic clamp holder, the silicone pad on the inner wall of the cover moves to contact the inner wall of the etching tank.

By incorporating a highly safe mechanism, the second fluoropolymer-lined centrifugal pump is controlled to draw hydrofluoric acid solution from the hydrofluoric acid solution tank into the corrosion tank through a pipeline, thus corroding the optical fiber inside. If the hydrofluoric acid solution in the tank becomes insufficient, it is replenished through the inlet and fixed pipes. The controller automatically controls the first fluoropolymer-lined centrifugal pump to draw hydrofluoric acid solution from the corrosion tank into the recovery tank through a suction pipe, storing the used hydrofluoric acid solution for subsequent processing. Subsequently, after the hydrofluoric acid solution in the corrosion tank is drawn out, the user operates the controller to activate the first water pump, which draws clean water from the clean water tank into the corrosion tank to clean it. This achieves a highly safe function for the optical fiber corrosion device, further enhancing its safety and automation during use. Attached Figure Description

[0023] Furthermore, such as Figure 2 and Figure 3As shown, the device box 1 is equipped with a high-safety mechanism 2, which consists of a fixed pipe 21, an inlet pipe 22, an installation pipe 23, a water inlet pipe 24, a first water pump 25, a first fluoropolymer-lined centrifugal pump 26, a second fluoropolymer-lined centrifugal pump 27, a container 28, and a second water pump 29. A container 28 is installed on the surface of the hydrofluoric acid solution tank 106, the clean water tank 108, the recovery tank 109, and the wastewater tank 110. The second fluoropolymer-lined centrifugal pump 27 is installed inside the container 28. The second fluoropolymer-lined centrifugal pump 27 can be an FSB series model.

The liquid tank 106 extends into the interior of the hydrofluoric acid solution tank 106. The output end of the second fluoropolymer-lined centrifugal pump 27 passes through the container 28 and the fiber optic clamp holder 104 in sequence and extends into the interior of the corrosion tank 111. The container 28 on the surface of the recovery tank 109 is equipped with a first fluoropolymer-lined centrifugal pump 26. The first fluoropolymer-lined centrifugal pump 26 can be an FSB series pump. The input end of the first fluoropolymer-lined centrifugal pump 26 is electrically connected to the output end of the controller 103. The output end of the first fluoropolymer-lined centrifugal pump 26 passes through the container 28 and the recovery tank 109 in sequence and extends into the interior of the recovery tank 109. A suction tube is installed at the input end of the first fluoropolymer-lined centrifugal pump 26, and one end of the suction tube passes through the container 28 and the fiber optic clamp holder 104 in sequence and extends into the interior of the corrosion tank 111. Clean water A first water pump 25, which can be an SLG series pump, is installed inside the container 28 on the surface of container 108. The input of the first water pump 25 is electrically connected to the output of controller 103. The input of the first water pump 25 passes through the container 28 and the clean water tank 108 and extends into the interior of the clean water tank 108. The output of the first water pump 25 passes through the container 28 and the fiber optic clamp holder 104 and extends into the interior of corrosion tank 111. A second water pump 29, which can be an SLG series pump, is installed inside the container 28 on the surface of wastewater tank 110. The input of the second water pump 29 is electrically connected to the output of controller 103. The input of the second water pump 29 passes through the container 28 and the fiber optic clamp holder. 104 extends into the interior of the corrosion tank 111. The output end of the second water pump 29 passes through the holding tank 28 and the sewage tank 110 in sequence and extends into the interior of the sewage tank 110. A fixed pipe 21 is installed on the surface of the top position of the hydrofluoric acid solution tank 106. The bottom end of the fixed pipe 21 passes through the hydrofluoric acid solution tank 106 and extends into the interior of the hydrofluoric acid solution tank 106. An inlet pipe 22 is installed on the surface of the fixed pipe 21 by screws. The inlet pipe 22 is connected to the interior of the fixed pipe 21.

The bottom end of the inlet pipe 24 passes through the clean water tank 108 and extends into the interior of the clean water tank 108.

[0024] During implementation, the second fluoropolymer-lined centrifugal pump 27 is controlled to operate. Under the action of the second fluoropolymer-lined centrifugal pump 27, the hydrofluoric acid solution inside the hydrofluoric acid solution tank 106 is sucked into the corrosion tank 111 through the pipeline to etch the optical fiber inside the corrosion tank 111. If the hydrofluoric acid solution inside the hydrofluoric acid solution tank 106 is insufficient, it is replenished into the hydrofluoric acid solution tank 106 through the inlet pipe 22 and the fixed pipe 21. Subsequently, the user can set the working time of the first fluoropolymer-lined centrifugal pump 26 by operating the controller 103. When the controller 103 calculates that the optical fiber inside the corrosion tank 111 has reached the corrosion time, the controller 103 automatically controls the first fluoropolymer-lined centrifugal pump 26 to operate. Under the action of the first fluoropolymer-lined centrifugal pump 26, the hydrofluoric acid solution inside the corrosion tank 111 is sucked into the recovery tank 109 through the suction pipe to store the used hydrofluoric acid solution for subsequent processing. Subsequently, when the hydrofluoric acid solution inside the corrosion tank 111 is insufficient, it is replenished. After the hydrofluoric acid solution is drawn out, the user operates the controller 103, which controls the first water pump 25 to operate. Under the action of the first water pump 25, clean water from the clean water tank 108 is drawn into the corrosion tank 111 to clean the inside of the corrosion tank 111. If the water level in the clean water tank 108 is insufficient, the user adds clean water to the clean water tank 108 through the installation pipe 23 and the water inlet pipe 24. Then, the user operates the controller 103 again, which controls the second water pump 29 to operate. Under the action of the second water pump 29, the cleaned wastewater from the corrosion tank 111 is drawn out and drawn into the wastewater tank 110 to store the cleaned wastewater for subsequent treatment. The entire process does not require direct human contact with the hydrofluoric acid solution, making the fiber optic corrosion device safer to use and achieving the high safety function of the fiber optic corrosion device.

[0025] Furthermore, such as Figure 2 and Figure 4 As shown, the surfaces of the fiber optic clamp holder 104 and the cover 105 are provided with a sealing and leak-proof mechanism 3. The sealing and leak-proof mechanism 3 consists of a sealing ring 31, a positioning block 32, a first rubber pad 33, a second rubber pad 34, and a silicone pad 35. The inner wall of the cover 105 is equipped with a positioning block 32, which engages with the surface of the fiber optic clamp holder 104. The inner wall of the cover 105 is equipped with a first rubber pad 33, and the surface of the fiber optic clamp holder 104 is equipped with a second rubber pad 34, which contacts the surface of the first rubber pad 33. The inner wall of the cover 105 is equipped with a silicone pad 35, which contacts the inner wall of the fiber optic clamp holder 104. The inner wall of the fiber optic clamp holder 104 is equipped with a sealing ring 31, which contacts the surface of the pipe and the suction tube.

[0026] During implementation, the cover 105 drives the positioning block 32 to automatically engage inside the fiber optic clamp holder 104. The cover 105 drives the first rubber pad 33 to contact the surface of the second rubber pad 34. Under the combined action of the first rubber pad 33 and the second rubber pad 34, a seal is formed between the fiber optic clamp holder 104 and the cover 105. When the cover 105 moves to the surface of the fiber optic clamp holder 104, the silicone pad 35 on the inner wall of the cover 105 moves to contact the inner wall of the etching tank 111. Under the action of the silicone pad 35, the sealing effect between the fiber optic clamp holder 104 and the cover 105 is further improved. Under the action of the sealing ring 31, the pipe and the suction tube are sealed with the fiber optic clamp holder 104, preventing the hydrofluoric acid solution inside the etching tank 111 from leaking, thus realizing the sealing and leak-proof function of the fiber optic etching device.

[0027] Working Principle: In use, first place the device box 1 in the designated location. The user places the optical fiber to be etched into the etching tank 111 inside the optical fiber clamp holder 104. The Teflon support 107 supports the optical fiber. Hydrofluoric acid solution from the hydrofluoric acid solution tank 106 enters the etching tank 111 to etch the optical fiber. The controller 103 controls and calculates the etching time. Then, after the optical fiber is placed into the etching tank 111 inside the optical fiber clamp holder 104, the user pulls the cover 105 inside the optical fiber clamp holder 104, causing the cover 105 to rotate on the surface of the optical fiber clamp holder 104. At this time, the cover 105 drives the positioning block 32 to automatically engage inside the optical fiber clamp holder 104. The cover 105 also moves the first rubber pad 33 to contact the surface of the second rubber pad 34. The first rubber pad 33 and the second rubber pad 34 work together to seal the fiber optic clamp 104 and the cover 105. When the cover 105 moves to the surface of the fiber optic clamp 104, the silicone pad 35 on the inner wall of the cover 105 moves to contact the inner wall of the etching tank 111. The silicone pad 35 further improves the sealing effect between the fiber optic clamp 104 and the cover 105. The sealing ring 31 seals the pipe and the suction tube with the fiber optic clamp 104, preventing leakage of the hydrofluoric acid solution inside the etching tank 111. This achieves the sealing and leak-proof function of the fiber optic etching device, allowing the fiber optic etching device to seal the fiber optic clamp 104 and the cover 105 during use, thus preventing the hydrofluoric acid gas inside the fiber optic clamp 104 from harming the health of the workers.

[0028] Subsequently, the user operates the controller 103 on the surface of the housing 102, causing the controller 103 to control the second fluoropolymer-lined centrifugal pump 27 to operate. Under the action of the second fluoropolymer-lined centrifugal pump 27, the hydrofluoric acid solution inside the hydrofluoric acid solution tank 106 is drawn into the corrosion tank 111 through the pipeline to etch the optical fiber inside the corrosion tank 111. If the hydrofluoric acid solution inside the hydrofluoric acid solution tank 106 is insufficient, it is replenished into the hydrofluoric acid solution tank 106 through the inlet pipe 22 and the fixed pipe 21. Then, the user operates the controller... The controller 103 can set the operating time of the first fluoropolymer-lined centrifugal pump 26. When the controller 103 calculates the time required for the optical fiber inside the corrosion tank 111 to reach the corrosion time, the controller 103 automatically controls the first fluoropolymer-lined centrifugal pump 26 to operate. Under the action of the first fluoropolymer-lined centrifugal pump 26, the hydrofluoric acid solution inside the corrosion tank 111 is sucked into the recovery tank 109 through a suction pipe to store the used hydrofluoric acid solution for subsequent processing. Subsequently, after the hydrofluoric acid solution inside the corrosion tank 111 is sucked out, the user operates the controller 103. 3. The controller 103 controls the first water pump 25 to operate, drawing clean water from the clean water tank 108 into the corrosion tank 111 to clean the interior of the corrosion tank 111. If the water level in the clean water tank 108 is insufficient, the user adds clean water to the tank through the installation pipe 23 and the inlet pipe 24. Then, the user operates the controller 103 to control the second water pump 29 to operate, drawing out the cleaned wastewater from the corrosion tank 111 and into the wastewater tank 110 for storage. This facilitates subsequent treatment of the wastewater in the wastewater tank 110. The entire process does not require direct human contact with the hydrofluoric acid solution, making the fiber optic corrosion device safer to use. This enhances the safety of the fiber optic corrosion device and improves its automation, ultimately completing the operation of the fiber optic corrosion device.
