Description

Technical Field

[0001] This application relates to the field of optical fiber technology, and in particular to an optical fiber preform processing apparatus. Background Technology

[0002] Optical fiber preform processing equipment is the manufacturing equipment for optical fibers, belonging to the category of optical fiber cables in optical communication, and specifically a specialized equipment or method for manufacturing conductors or cables. Currently, when processing the tapered portion of optical fiber preforms, the tail end is typically softened, then heated in a furnace to soften and shape the preform, detaching the tail end to form an arc-shaped tapered portion. The preform is then removed from the equipment and allowed to cool before inspection. Some preforms that fail the tapered portion inspection need to be reloaded into the furnace for a second softening treatment until the final appearance and dimensions meet the standards before being released for further processing. However, this process consumes a significant amount of electricity, resulting in high costs. Furthermore, repeated high-temperature softening treatments lead to material waste and scrap, and are also time-consuming. Summary of the Invention

[0003] To address the issues of low processing efficiency and high cost in the taper section of optical fiber preforms, this application provides an optical fiber preform processing apparatus that offers higher efficiency and lower cost.

[0004] This application provides an optical fiber preform processing apparatus for processing optical fiber preforms. The apparatus includes a clamping assembly, a dicing mechanism, and a grinding mechanism. The clamping assembly is used to clamp the optical fiber preform. The dicing mechanism is spaced apart from the clamping assembly along a first direction, and is configured to move relative to the clamping assembly to dic the optical fiber preform. The grinding mechanism is spaced apart from the clamping assembly along the first direction, and is configured to move relative to the clamping assembly to grind the optical fiber preform.

[0005] Understandably, by clamping the optical fiber preform with a clamping assembly, and then precisely machining the tail of the preform using the cutting and grinding mechanisms, the preform's tapered portion is prevented from deviating due to furnace instability during heating. Furthermore, directly machining the tail of the preform eliminates the need for repeated inspections and machining to achieve a satisfactory result, reducing processing costs while improving efficiency.

[0008] In one embodiment, the cutting mechanism further includes a detection element connected to the first connector, the detection element being used to detect the location of the optical fiber preform that needs to be processed.

[0022] like Figure 1 As shown, this application provides an optical fiber preform processing apparatus 100 for processing optical fiber preforms 200. The optical fiber preforms 200 are used to form optical fibers after processing. The optical fiber preform processing apparatus 100 of this application is an optical fiber manufacturing equipment, belonging to the category of optical fiber cables in optical communication, and is more specifically a special equipment or method for manufacturing conductors or cables.

[0023] The optical fiber preform processing device 100 includes a clamping assembly 1, a cutting mechanism 2, and a grinding mechanism 3. The clamping assembly 1 is used to clamp the optical fiber preform 200.

[0024] For ease of reading, this application introduces the terms first direction Z, second direction X, and third direction Y to describe the embodiments of this application. The first direction Z, second direction X, and third direction Y can be three non-parallel straight lines in space; further, the first direction Z, second direction X, and third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is described as the Z-axis direction of the three-dimensional coordinate system, the second direction X as the X-axis direction of the three-dimensional coordinate system, and the third direction Y as the Y-axis direction of the three-dimensional coordinate system.

[0025] The cutting mechanism 2 and the clamping assembly 1 are spaced apart along the first direction Z. The cutting mechanism 2 is configured to move relative to the clamping assembly 1, that is, the cutting mechanism 2 can move along the first direction Z and the second direction X to cut the optical fiber preform 200. The grinding mechanism 3 and the clamping assembly 1 are spaced apart along the first direction Z. The grinding mechanism 3 is configured to move relative to the clamping assembly 1, that is, the grinding mechanism 3 can move along the first direction Z and the second direction X to grind the optical fiber preform 200.

[0026] In this embodiment, the optical fiber preform processing apparatus 100 performs tapered processing on the tail end of the optical fiber preform 200. The optical fiber preform processing apparatus 100 also includes a support 5. Along the third direction Y, the optical fiber preform 200 is movably connected to the support 5. The sintered optical fiber preform 200 can be moved along the third direction Y to the processing position. At the processing position, the optical fiber preform 200 is in a suspended state, that is, the tail end of the optical fiber preform 200 is located at one end of the optical fiber preform 200 in the first direction Z. The clamping assembly 1, the cutting mechanism 2, and the grinding mechanism 3 are all connected to the support 5. Two clamping assemblies 1 can be spaced apart along the first direction Z to clamp the optical fiber preform 200 at two positions in the first direction Z, ensuring that the optical fiber preform 200 can be well clamped by the clamping assembly 1.

[0027] In one embodiment, the clamping assembly 1 includes a second driving member 11 and a clamping member 12. The second driving member 11 is connected to the clamping member 12 in a transmission manner. The second driving member 11 drives the clamping member 12 to move along a second direction X. Along the second direction X, the clamping member 12 can abut against the optical fiber preform 200.

[0028] In this embodiment, two second driving members 11 and two clamping members 12 can be provided. Each second driving member 11 is connected to one clamping member 12. The two clamping members 12 are spaced apart along the second direction X. The two clamping members 12 abut against both sides of the optical fiber preform 200 in the second direction X to properly clamp the optical fiber preform 200 at that position. The second driving member 11 can be a cylinder, or other driving components can be used, as long as they can drive the clamping members 12 to move along the second direction X. No further restrictions are imposed here. The second driving member 11 can also be connected to a solenoid valve and a magnetic switch to control whether it drives the clamping members 12. The clamping member 12 can be a block-shaped object, on which a limiting groove can be formed corresponding to the optical fiber preform 200, so that when the optical fiber preform 200 is partially located in the limiting groove, it can abut against the groove wall and be limited. Both clamping members 12 are arranged in this way to achieve clamping of the optical fiber preform 200.

[0029] In this embodiment, the cutting mechanism 2 and the grinding mechanism 3 can be located at the tail end of the optical fiber preform 200 to process the tail end of the optical fiber preform 200. The cutting mechanism 2 and the grinding mechanism 3 can be spaced apart along the second direction X. The cutting mechanism 2 can include cutting components such as cutting tools to cut the tail end of the optical fiber preform 200, and the cutting tool can be driven by a motor or other driving components to move along the first direction Z and the second direction X, thereby cutting the optical fiber preform 200 at the location requiring processing. Similarly, the grinding mechanism 3 can include grinding components such as grinding tools to grind the tail end of the optical fiber preform 200, and the grinding tool can be driven by a motor or other driving components to move along the first direction Z and the second direction X, thereby grinding the optical fiber preform 200 at the location requiring processing.

[0030] Understandably, by clamping the optical fiber preform 200 with the clamping assembly 1, and precisely machining the tail of the optical fiber preform 200 with the cutting mechanism 2 and the grinding mechanism 3, the taper of the preform 200 is prevented from deviating due to furnace instability caused by heating the preform 200 in the furnace. Furthermore, directly machining the tail of the preform 200 eliminates the need for repeated inspections and machining to achieve a satisfactory result, reducing processing costs and improving efficiency. This optical fiber preform processing device 100 solves the taper machining problem more quickly and cost-effectively, avoiding the waste of multiple repetitive processes, reducing energy consumption, equipment failure rate, and maintenance costs, and decreasing the labor intensity of operators. It also eliminates the waste of finished products due to substandard machining.

[0031] Further integration Figure 2 As shown, in one embodiment, the cutting mechanism 2 includes a cutting element 21 and a first lifting assembly 22. Along the second direction X, the cutting element 21 is movably connected to the first lifting assembly 22, and the cutting element 21 can be moved along the first direction Z by the first lifting assembly 22. The first lifting assembly 22 includes a slide rail 221 and a first connecting member 222. Along the first direction Z, the first connecting member 222 is movably connected to the slide rail 221, and along the second direction X, the cutting element 21 is movably connected to the first connecting member 222.

[0032] In this embodiment, the cutting element 21 can be a cutting blade or a cutting tool; no further restrictions are imposed. The first lifting assembly 22 may include a slide rail 221, a motor, and a first connecting member 222. The motor can drive the first connecting member 222 to move along the slide rail 221. The first connecting member 222 may be an L-shaped block, allowing it to move along the first direction Z while also enabling the cutting element 21 to be movably connected to the first connecting member 222 along the second direction X. The cutting mechanism 2 also includes a cutting motor that drives the cutting element 21 to rotate, thereby enabling cutting.

[0033] It is understandable that the first lifting component 22 enables the cutting component 21 to be moved along the first direction Z, thereby adjusting the position of the cutting component 21 so that the cutting component 21 can accurately process the position of the optical fiber preform 200 that needs to be processed, thereby improving processing efficiency and processing accuracy.

[0034] In one embodiment, the cutting mechanism 2 further includes a first transverse component 23, which is connected to the first connector 222. The first transverse component 23 is connected to the cutting component 21 and can drive the cutting component 21 to move along the second direction X.

[0035] In this embodiment, the first lateral movement component 23 may include a third driving member, which is connected to the cutting member 21. The third driving member may be a motor or other component that can drive the cutting member 21 to move along the second direction X, without further restrictions.

[0036] It is understandable that by setting the first transverse component 23, the cutting component 21 can be driven to move along the second direction X, thereby further adjusting the position of the cutting component 21 and cutting the optical fiber preform 200, thus improving the processing accuracy.

[0037] In one embodiment, the cutting mechanism 2 further includes a detection element 24 connected to the first connector 222, and the detection element 24 is used to detect the position of the optical fiber preform 200 that needs to be processed.

[0038] In this embodiment, the detection element 24 can be an infrared instrument. By observing the position of the infrared light generated by the infrared instrument at the tail end of the optical fiber preform 200, the position of the first connector 222 in the first direction Z is adjusted, thereby adjusting the position of the cutting element 21 in the first direction Z. The detection element 24 determines the required target position to find the position of the optical fiber preform 200 that needs to be processed, so that the cutting element 21 can process that position.

[0039] Understandably, the setting of the detection element 24 allows the position of the optical fiber preform 200 that needs to be processed to be detected, thereby enabling the cutting element 21 to be adjusted to process the position that needs to be processed, further improving the processing accuracy. At the same time, processing only the position that needs to be processed also improves the processing efficiency.

[0040] In one embodiment, the cutting mechanism 2 further includes a first cooling element 25, which is connected to a first connecting element 222 and is used to cool the cutting element 21.

[0041] In this embodiment, the first cooling element 25 may be a cooling nozzle and a water pipe. The cooling nozzle is aimed at the cutting element 21, and the water pipe can carry cold water and flow out from the nozzle so that the cold water can fall on the cutting element 21 to cool it down. The first cooling element 25 may also be connected to a valve, which controls the opening and closing of the water pipe to control whether the cutting element 21 is cooled.

[0042] It is understandable that by setting the first cooling element 25, when the temperature of the cutting element 21 is too high during the cutting process and affects the processing, the first cooling element 25 can be used to cool down the cutting element 21 and ensure a better processing process.

[0043] Further integration Figure 3 As shown, in one embodiment, the grinding mechanism 3 includes a grinding component 31, a second lifting component 32, and a second lateral movement component 33. Along the second direction X, the second lifting component 32 is movably connected to the second lateral movement component 33, and along the first direction Z, the grinding component 31 is movably connected to the second lifting component 32.

[0044] In this embodiment, the grinding component 31 can be a grinding tool, as long as it can grind the optical fiber preform 200, without further restrictions. The second traverse assembly 33 can be a lead screw slide, capable of driving the second lifting assembly 32 to move along the second direction X. The second lifting assembly 32 can also be a lead screw slide, capable of driving the grinding component 31 to move along the first direction Z. The grinding mechanism 3 further includes a fourth drive component 35, which can be an electric rotary table, and is connected to the grinding component 31 to drive the grinding component 31 to rotate. Along the first direction Z, the fourth drive component 35 is movably connected to the second lifting assembly 32.

[0045] It is understandable that by setting the second lifting component 32 and the second transverse component 33, the position of the grinding component 31 can be adjusted so that the grinding component 31 can be adjusted to a suitable position and the optical fiber preform 200 can be ground well, thereby making the tail of the optical fiber preform 200 better processed.

[0046] In one embodiment, the grinding mechanism 3 further includes a second cooling element 34, which is connected to the grinding element 31 and cools the grinding element 31.

[0047] In this embodiment, the second cooling element 34 can be a cooling nozzle and a water pipe. The cooling nozzle is aimed at the grinding workpiece 31, and the water pipe can carry cold water and flow out from the nozzle so that the cold water can fall on the grinding workpiece 31 to cool it down. The second cooling element 34 can also be connected to a valve, which controls the opening and closing of the water pipe to control whether the grinding workpiece 31 is cooled.

[0048] In other embodiments, the optical fiber preform processing apparatus 100 further includes a drainage component 6, which may be a drainage trough, located at the end of the cutting mechanism 2 and the grinding mechanism 3 away from the clamping assembly 1 in the first direction Z, i.e., below the cutting mechanism 2 and the grinding mechanism 3, to receive and discharge wastewater generated during the operation of the first cooling component 25 and the second cooling component 34.

[0049] Understandably, the second cooling element 34 is designed to cool down the grinding part 31 when its temperature is too high during grinding, thus ensuring a better processing result.

[0050] Further integration Figure 4 As shown, in one embodiment, the optical fiber preform processing apparatus 100 further includes a moving component 4, which is configured to drive the optical fiber preform 200 to move along a third direction Y. The moving component 4 includes a first driving member 41 and a second connecting member 42. The first driving member 41 is driveably connected to the second connecting member 42 and can drive the second connecting member 42 to move along a third direction Y. The optical fiber preform 200 is connected to the second connecting member 42.

[0051] In this embodiment, the first driving component 41 can be a servo motor, a planetary reducer, and a ball screw extending in the third direction Y. The servo motor and the planetary reducer are connected to the second connecting component 42 via a coupling to drive the second connecting component 42 to move. The moving component 4 also includes a guide rail 43, which is connected to the bracket 5 and extends in the third direction Y. The second connecting component 42 is movably connected to the guide rail 43 and moves along the guide rail 43 under the drive of the first driving component 41. The second connecting component 42 can be a rod-shaped object with a connecting groove. The optical fiber preform 200 can be snapped into the connecting groove to connect with the second connecting component 42 and be driven by the second connecting component 42 to move in the third direction Y. The guide rail 43 is also provided with an origin switch, which is set at the processing position of the optical fiber preform 200 so that when the second connecting component 42 moves to the origin switch, it can receive a signal that it has moved to the correct position and stop moving.

[0052] It is understandable that by setting the moving component 4, the optical fiber preform 200 can be moved along the third direction Y until it is moved to the position for processing, so that subsequent processing can be carried out.

[0053] In other embodiments, the optical fiber preform processing apparatus 100 further includes a control system 7, which may include a touch screen, a PLC, and other electrical components to control the processing process, thereby improving processing accuracy and efficiency.

[0054] The operation process of this optical fiber preform processing device 100 is as follows: (1) After the optical fiber preform 200 is sintered, it is transferred to the vicinity of the optical fiber preform processing device 100 by a vertical transport trolley. After reaching the designated position, the optical fiber preform processing device 100 starts to work.

[0055] (2) Click the “Start” button on the touch screen of the control system 7. The control system 7 starts to run. The second connector 42 in the moving component 4 starts to move along the third direction Y to connect the optical fiber preform 200 with the second connector 42. After the connection is stable, the second connector 42 starts to move along the third direction Y to the processing position.

[0056] (3) When the operator clicks the “STEP1” button on the touch screen of the control system 7, the clamping component 1 starts to work. The control system 7 sends a signal to the solenoid valve to drive the second drive component 11. The second drive component 11 drives the clamping component 12 to move along the second direction X. The clamping components 12 on both sides of the second direction X synchronously squeeze the optical fiber preform 200 until it reaches the position. Then the magnetic switch senses the position, and the second drive component 11 stops driving. The two clamping components 1 work synchronously.

[0057] (4) Click the “STEP2” button on the touch screen of the control system 7. The cutting mechanism 2 starts to work. The detection component 24 is aligned with the tail end of the optical fiber preform 200. The position of the first connector 222 can be adjusted manually along the first direction Z, thereby adjusting the position of the detection component 24. By observing the position of the infrared light emitted by the detection component 24 at the tail end of the optical fiber preform 200, the first lifting module is operated to determine the target position to be processed.

[0058] (5) By clicking the “STEP3” button on the touch screen of the control system 7, the first transverse component 23 of the cutting mechanism 2 starts to feed at a speed of 20~100mm / min. At the same time, the cutting motor starts and the cutting part 21 starts to rotate at a speed of 3000~6000r / min. The first water cooling component starts and the cooling nozzles start to flow water. All the wastewater falls into the drainage component 6, completing the cutting operation. The cutting mechanism 2 automatically retreats to the origin.

[0059] (6) By clicking the “STEP4” button on the touchscreen of the control system 7, the grinding mechanism 3 starts to run. The second lifting component 32 moves to the bottom, and the second lateral component 33 moves from one side in the second direction X to the designated position. After the center is aligned, the fourth drive component 35 starts to run at a speed of 3000~9000 r / min. The second cooling component 34 starts, and the cooling nozzles start to flow water. The grinding component 31 rotates rapidly. A protective cover can be set outside the grinding mechanism 3 to limit water splashing and protect the equipment components. The second lifting component 32 starts to move upward along the first direction Z at a speed of 1~10 mm / min until the grinding operation is completed. The grinding mechanism 3 then moves downward along the first direction Z and backward to the left along the second direction X back to the origin.

[0060] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
