Description

Technical Field

[0001] This invention relates to the field of optical fiber manufacturing, and more particularly to a fused taper machine for optical fiber manufacturing. Background Technology

[0002] Fused tapering is one of the core processes in the manufacture of passive optical devices such as fiber optic couplers and wavelength division multiplexers. It involves softening and simultaneously stretching multiple optical fibers through high-temperature heating to form a tapered transition region, thereby achieving precise coupling and splitting of optical power. Due to its advantages such as low insertion loss, good process repeatability, and small device size, this technology has wide application value in fields such as optical fiber communication, optical fiber sensing, and lasers, and has become a key means for the mass production of high-performance optical fiber devices.

[0003] Although existing fusion tapering equipment integrates functional modules such as fiber supply, coating cleaning, and tapering, it still has significant shortcomings: First, the whole machine adopts a single-station serial operation mode, which can only process one or two fibers at a time, resulting in low production efficiency and difficulty in meeting the needs of mass production; Second, the coating removal and cleaning processes are carried out in separate steps, with the cleaning and tapering processes being independent of each other, resulting in a complex equipment structure and long operation cycle; Third, there is a lack of dynamic cleaning mechanism for the fiber surface during the tapering process, and debris or contaminants remaining on the bare fiber surface may affect the fusion quality and device reliability.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention achieves simultaneous feeding, drawing, cleaning, and tapering of multiple optical fibers by setting multiple sets of fusion tapering structures on the outer periphery of the discharge box and coordinating them with a multi-discharge station discharge structure. This multi-station parallel working mode not only increases the number of optical fibers processed in a single cycle by several times, but also ensures that the process conditions (cleaning intensity, melting temperature, tapering speed, etc.) experienced by each optical fiber are highly consistent, thereby improving production capacity while ensuring the uniformity and repeatability of product quality. This invention directly couples the extension and retraction of the molten tapered section with the cleaning fluid intake / discharge process of the second cleaning section. Before molten tapering, the molten tapered section moves towards the discharge box, squeezing the inlet and outlet annular cavities to automatically discharge the residual waste fluid from the previous cleaning. During molten tapering, the molten tapered section moves in the opposite direction to stretch the cavity, automatically drawing in fresh cleaning fluid and driving the spray head to clean the optical fiber. This linkage mechanism eliminates the need for an additional independent pump drive unit; the mechanical movement of the tapering action itself is sufficient to dynamically update and spray the cleaning fluid, reducing equipment energy consumption and control complexity. Simultaneously, the alternating arrangement of the inlet and outlet annular cavities, along with the one-way valve and return head, ensures that the cleaning fluid always flows in one direction, preventing secondary contamination and making the secondary cleaning both thorough and efficient. This invention integrates primary cleaning (mechanical friction removal of the coating), secondary cleaning (spray cleaning + hot air drying), fusion heating and differential tapering, as well as post-tapering gas protection and coating spraying, into a single fusion tapering structure. A lead-in structure allows the optical fiber to pass through all functional segments sequentially in one pass. Throughout the entire lead-in process, the optical fiber continuously undergoes coating removal, surface cleaning, high-temperature melting, precision tapering, and immediate protection. The melt generator employs laser heating and a PID closed-loop temperature control system, working in conjunction with a rotating ring to achieve uniform circumferential heating of the fiber. The differential movement of the front and rear mounting rings precisely controls the tapering angle and tapered shape. Protective gas and coating are simultaneously sprayed from two nozzles, effectively suppressing high-temperature oxidation and strengthening the tapered area. This highly integrated continuous operation mode shortens the process flow, reduces the opportunity for the optical fiber to be exposed to a polluted environment, thereby reducing the defect rate of fiber breakage, surface defects, oxidation, etc., and improving yield and device performance.

[0017] Example 1: This invention proposes a fused taper machine for optical fiber manufacturing, such as... Figures 1-2As shown, the system includes a base 1; a discharge box 2 is located in the middle of the base 1; the discharge box 2 contains a discharge structure 3 with multiple discharge stations, and multiple sets of fused taper structures 4 are arranged around the outer periphery of the discharge box 2; one end of each set of fused taper structures 4 corresponds to a discharge station of the discharge structure 3, and the other end is equipped with a feeding structure 5; the fused taper structure 4 includes a first cleaning section 401, a second cleaning section 402, and a fused taper section 403 connected sequentially along the optical fiber's movement trajectory; the first cleaning section 401 is fixedly connected to the discharge box 2 and removes the outer cladding of the optical fiber through horizontally staggered force application from multiple sets of cleaning ends; the second cleaning section 402 performs secondary cleaning of the optical fiber using a spray cleaning solution. The structure uses a telescopic mechanism to introduce clean cleaning fluid when elongated and to expel contaminated cleaning fluid when compressed. The fused tapered section 403 adopts a movable telescopic structure with a fusion end in the middle and rotatable tapered ends on both sides. On the one hand, it moves to extend and retract the second cleaning section 402, and on the other hand, it fused and tapered the optical fiber. The angle of the tapered section is adjustable. A cutting element is set between the second cleaning section 402 and the fused tapered section 403. The feeding structure 5 is equipped with a telescopic and translational feeding end. The feeding end leads the optical fiber from the discharge station through the fused tapered structure 4 and passes through the first cleaning section 401, the second cleaning section 402, and the fused tapered section 403 in sequence.

[0018] It should be further explained that the base 1 is provided with a slide groove 101; the melting tapered section 403 is slidably disposed at one end of the slide groove 101; and the feeding structure 5 is slidably disposed at the other end of the slide groove 101.

[0019] Before the fusion tapering, the fusion tapering section 403 moves towards the discharge box 2, compressing the second cleaning section 402. The feed structure 5 approaches the compressed fusion tapering structure 4, and the feed end passes through the fusion tapering section 403, the second cleaning section 402, and the first cleaning section 401, leading out one end of the optical fiber, and then leading the optical fiber out of the fusion tapering structure 4. During the lead-out process, the optical fiber is cleaned twice and fused tapered, with the fusion tapering section 403 coordinating with synchronous extension, contraction, and movement.

[0020] like Figure 3 As shown, the discharge structure 3 includes a discharge column 301 located inside the discharge box 2; a slide rail 1 and multiple sets of sliders 302 that cooperate with the slide rail 1 are provided on the side wall of the discharge column 301; a discharge roller 305 with optical fiber wound around it and corresponding to the discharge station is provided on the outside of the discharge column 301; a guide sleeve 304 for optical fiber to pass through and corresponding to the discharge station is provided on the discharge box 2; the slider 302 is located between the pair of guide sleeves 304 and the discharge roller 305, and moves along the slide rail 1 in an arc trajectory; the slider 302 is provided with a retractable latch 303 for optical fiber to pass through.

[0021] It should be further explained that the locking buckle 303 has a U-shaped structure, and the tension of the optical fiber can be controlled by extending and retracting it to lock it in place.

[0022] The optical fiber is wound around the discharge roller 305, and after the end is led out, it passes through the U-shaped locking buckle 303, and then leads out of the discharge box 2 through the guide sleeve 304. Since the U-shaped locking buckle 303 is retractable, the optical fiber can be locked and positioned when needed.

[0023] like Figure 4 As shown, the first cleaning section 401 includes a first cleaning cylinder 40101 connected to the discharge box 2; both ends of the first cleaning cylinder 40101 are provided with fiber threading rings 40102, one set of fiber threading rings 40102 is connected to the guide sleeve 304, and the other set of fiber threading rings 40102 is connected to the second cleaning section 402. A cleaning component is provided inside the first cleaning cylinder 40101; positioning and cutting components are provided on both sides of the cleaning component in a mirror image.

[0024] like Figure 5 As shown, the cleaning assembly includes a rotating disk 40104 that rotates along the inner wall of a cleaning cylinder 40101; a cleaning port is provided on the rotating disk 40104; a retractable lifting platform 40109 is provided above and below the cleaning port; the opposite ends of the two lifting platforms 40109 are the cleaning ends, and a slide rail 2 and a cleaning seat 40110 that cooperates with the slide rail 2 are provided on the opposite ends; the upper and lower cleaning seats 40110 remove the outer coating of the optical fiber by friction through horizontal and reverse movement.

[0025] It should be further noted that the cleaning seat 40110 is equipped with a reinforcing protrusion 40111.

[0026] like Figure 6 As shown, the positioning and cutting assembly includes a rotating disk 40103 that rotates along the inner wall of the first cleaning cylinder 40101; the second rotating disk 40103 is provided with a positioning cutting opening 40106 and grooves located on both sides of the positioning cutting opening 40106; the second cutting piece 40107 is disposed in the groove; the first positioning piece 40108 is located outside the second rotating disk 40103 and is staggered with the groove.

[0027] It should be further explained that the second cutting component 40107 and the first cutting component (not shown in the figure) have the same structure, are set in pairs, and are retractable cutting blades.

[0028] It should be further noted that a fiber threading ring 40102 is provided inside the positioning cut 40106.

[0029] The optical fiber enters the cleaning cylinder 40101 from the fiber loop 40102 on one side, passes through the positioning cut-off port 40106 and the cleaning port, and then extends out from the fiber loop 40102 on the other side. Positioning element 40108 positions the optical fiber from both ends. The cleaning seats 40110 on both sides approach and adhere to the optical fiber, removing the outer coating of the fiber through horizontal and counter-directional movement. Since both rotating disks 40104 and 40103 can rotate, the optical fiber can be twisted, and the cleaning end can also rotate, thus ensuring comprehensive and thorough friction cleaning. After fusion tapering is completed, cutting element 40107 and cutting element 40107 can cut the optical fiber.

[0030] It should be further explained that a positioning airbag ring 40105 connected to an inflation / deflation pump is provided inside the fiber optic ring 40102; when the positioning airbag ring 40105 is inflated, it can clamp the optical fiber inside the fiber optic ring 40102, thereby achieving the effect of positioning the optical fiber and preventing it from slipping out after being broken.

[0031] like Figure 7 As shown, the second cleaning section 402 includes two sets of cleaning rings 40201; one set of cleaning rings 40201 is connected to the first cleaning cylinder 40101, and the other set of cleaning rings 40201 is connected to the melting tapered section 403; both sets of cleaning rings 40201 are equipped with nozzles 40202 connected to an external pressurized air pump, and multiple sets of retractable liquid inlet ring chambers 40203 and liquid outlet ring chambers 40204 are sequentially connected between the two sets of cleaning rings 40201.

[0032] It should be further explained that the inlet ring chamber 40203 and the outlet ring chamber 40204 are arranged alternately; the inlet ring chamber 40203 is connected to an external cleaning fluid storage device through a one-way inlet pressure valve, and a spray head 40205 connected to a pressure pump is installed above the inner wall of the inlet ring chamber 40203; the outlet ring chamber 40204 is connected to an external waste liquid storage device through a one-way outlet pressure valve, and a return head 40206 for a water pump is installed below the inner wall of the outlet ring chamber 40204.

[0033] After the optical fiber completes one cleaning cycle, it enters cleaning section two 402. The cleaning ring 40201, located at the front, sprays air through nozzle one 40202 to clean the debris adhering to the optical fiber. The fused tapered section 403 first moves to compress the inlet ring cavity 40203 and the outlet ring cavity 40204, discharging the original waste liquid in the outlet ring cavity 40204. Then, it moves in the opposite direction to stretch the inlet ring cavity 40203 and the outlet ring cavity 40204, introducing external cleaning fluid into the inlet ring cavity 40203. The upper spray head 40205 sprays and cleans the optical fiber. The lower return head 40206 transfers the sprayed waste liquid to the outlet ring cavity 40204. Therefore, the movement of the fused tapered section 403 causes the inlet ring cavity 40203 and the outlet ring cavity 40204 to expand and contract, thereby controlling the entry and exit of the cleaning fluid and achieving dynamic cleaning. When the optical fiber moves to the rear cleaning ring 40201, it is dried by air jets from nozzle 40202. Hot air can be introduced during the drying process to further improve the optical fiber's performance.

[0034] like Figures 8-9 As shown, the molten tapered section 403 includes two sets of mounting rings 40301; one set of mounting rings 40301 is connected to the cleaning ring 40201, and the other set of mounting rings 40301 is positioned opposite to the feeding structure 5; a rotating ring 40302 is provided on the inner wall of each set of mounting rings 40301; mounting seats 40303 are provided on both sides of the rotating ring 40302; a second sliding groove and a second positioning element 40304 that moves horizontally along the second sliding groove are provided on the mounting seats 40303; the two sets of mounting rings 40301... An inner sliding sleeve 40307 is provided on the opposite end of 0301; an outer telescopic sleeve 40308 is slidably provided on the outside of the two sets of inner sliding sleeves 40307; a boss is provided on the inner wall of the middle part of the outer telescopic sleeve 40308; a melter 40305 is provided on the boss, and annular grooves are provided on both sides of the boss; the annular grooves are opened and closed by the relative sliding of the inner sliding sleeves 40307 and the outer telescopic sleeves 40308, and a nozzle 40306 connected to the external paint storage device and the protective air source is provided in the annular groove.

[0035] It should be further explained that the melter 40305 is the melting end; the positioning part 40304 is the tapered end.

[0036] It should be further explained that the 40305 melters are uniformly distributed along the circumference and employ laser heating. Utilizing a high-energy laser beam as the heat source, they offer advantages such as stable heat source, concentrated energy, and controllable heating area. The temperature of the heating area is monitored in real-time by a lower-level computer and fed back to the upper-level computer. The upper-level computer then adjusts the tapering speed of the tapering platform based on temperature changes, forming a closed-loop control system to ensure the stability of the melting process and the yield of the fiber optic splitting ratio. To ensure precise control of the melting temperature, a complete temperature control system is provided. This system is based on the PID (Proportional-Integral-Derivative) control method and can continuously adjust the heating power in real time. By precisely controlling parameters such as current and voltage, it can effectively address issues such as thermal inertia and ensure long-term stability of the temperature field.

[0037] The fused tapered section 403 first moves, causing the inlet annular cavity 40203 and the outlet annular cavity 40204 to expand and contract, thereby controlling the entry and exit of the cleaning fluid and achieving dynamic cleaning. The optical fiber enters the fused tapered section 403, where the central melter 40305 heats and melts it. The rotation of the rotating ring 40302 adjusts the rotation of the optical fiber, changing the angle and position of heating to ensure uniform melting. The fused tapered section 403 then moves forward, during which it draws the cleaning fluid into the inlet annular cavity 40203 of the second cleaning section 402. Simultaneously, the two sets of mounting rings 40301 at the front and rear move at different speeds (one fast, one slow) to tapere the fused optical fiber. During this pulling motion, the relative sliding of the inner sliding sleeve 40307 and the outer telescopic sleeve 40308 exposes the second nozzle 40306. The second nozzle 40306 sprays coating onto the tapered optical fiber to prevent oxidation. During the tapering process, protective gas is introduced through nozzles 40306 on two sets of mounting rings 40301. The feed structure 5 then leads the molten tapered optical fiber out of the device. The cutting component 40107 cuts the optical fiber.

[0038] like Figure 10 As shown, the feeding structure 5 includes a sliding column 501 slidably disposed on a slide groove 101; a rotatable rotating table 502 is disposed on the sliding column 501; an installation through groove is disposed on the rotating table 502 and a telescopic feeding rod 503 that moves horizontally along the installation through groove; a feeding assembly 504 is disposed on the telescopic end of the telescopic feeding rod 503.

[0039] The sliding column 501 drives the telescopic feed rod 503 to move, the rotary table 502 drives the telescopic feed rod 503 to rotate, and the telescopic feed rod 503 drives the feed assembly 504 to move back and forth, so that the feed assembly 504 can cooperate with the telescopic adjustment position of the fused tapered structure 4 to lead out the optical fiber while entering and exiting the fused tapered structure 4.

[0040] like Figure 11As shown, the feeding assembly 504 includes a rotating head 50401 that is rotatably connected to the telescopic end of the telescopic feeding rod 503; a hole 50402 for the optical fiber end to enter is provided in the middle of the rotating head 50401; and positioning elements 50403 are provided on both sides of the hole 50402.

[0041] It should be further noted that a negative pressure environment is set inside hole 50402.

[0042] By rotating, extending, and moving, the rotating head 50401 moves to the foremost fiber threading ring 40102, guiding the end of the optical fiber into the hole 50402. The positioning components 50403 on both sides further position the optical fiber, and then the optical fiber is sequentially led out through the first cleaning section 401, the second cleaning section 402, and the fused taper section 403. During the pulling process, primary cleaning, secondary cleaning, and fused tapering are completed.

[0043] It should be further noted that positioning component 1 (40108), positioning component 2 (40304), and positioning component 3 (50403) are all set in pairs and have the same structure.

[0044] Positioning component 3 50403 includes a telescopic drive platform located on the rotating head 50401; positioning blocks are provided on the opposite ends of the two sets of telescopic drive platforms; V-grooves are provided on the positioning blocks; suction holes for connecting vacuum pumps are provided on the groove walls and both sides of the V-grooves.

[0045] During fiber optic positioning, the fiber extends between two sets of positioning blocks. The positioning blocks on both sides move closer together to clamp the fiber, locking it in the V-groove. At the same time, negative pressure is generated at the adsorption hole, further adsorbing and positioning the fiber.

[0046] Example 2: Based on the fused taper machine for optical fiber manufacturing described in the above examples, this example proposes a fused taper method for optical fiber manufacturing, with the following steps: S1. Multi-station synchronous feeding and pre-adjustment: The optical fiber is wound around the corresponding discharge roller 305, and the end passes through the U-shaped latch 303 on the slider 302 and the guide sleeve 304 on the discharge box 2 in sequence. The tension of each optical fiber is adjusted and locked by the telescopic U-shaped latch 303. Then all the molten tapered sections 403 move synchronously towards the discharge box 2 along the slide groove 101 on the base 1, compressing the liquid inlet ring cavity 40203 and liquid outlet ring cavity 40204 in their respective corresponding cleaning sections 402. The original waste liquid in the liquid outlet ring cavity 40204 is discharged to the external waste liquid storage device through the one-way liquid outlet pressure valve. At the same time, multiple sets of feeding structures 5 move along the slide groove 101 to the molten tapered structure 4 in the compression state to complete the feeding preparation. S2. Fiber threading at the feed end and synchronous feed at multiple stations: The sliding column 501 of each feed structure 5 drives the telescopic feed rod 503 to move. The rotary table 502 adjusts the angle, and the telescopic feed rod 503 extends so that the rotating head 50401 of the feed assembly 504 is aligned with the fiber threading ring 40102 at the front end of the first cleaning section 401. A negative pressure environment is established in the hole 50402 of the rotating head 50401, and the end of the optical fiber is introduced into the hole 50402. The positioning parts 50403 on both sides (V-groove with adsorption hole) clamp and adsorb and position it. Then the feed structure 5 moves in the opposite direction, pulling the optical fiber through the first cleaning section 401, the second cleaning section 402 and the fused tapered section 403 in sequence. During this process, the feed actions of multiple stations are carried out synchronously to ensure that each optical fiber enters the subsequent processing stage at the same time. S3. Simultaneous removal of coating in multiple stations during a single cleaning process: When the optical fiber passes through cleaning section 1 401, the positioning components 40108 in each station axially position the optical fiber from both sides. At the same time, the lifting platform 40109 in the cleaning cylinder 40101 drives the upper and lower cleaning seats 40110 to approach and adhere to the surface of the optical fiber. The cleaning seats 40110 move horizontally and in the opposite direction along the slide rail 2, working with the reinforcing protrusions 40111 to remove the outer coating of the optical fiber through friction. The rotating disk 40104 and the rotating disk 40103 drive the cleaning components and the positioning and cutting components to rotate, causing the optical fiber to twist and the cleaning end to rotate, achieving comprehensive cleaning. Multiple cleaning sections 401 work simultaneously, ensuring the high efficiency and consistency of single cleaning at all stations. S4. Secondary cleaning, dynamic spraying with moving linkage of the fused tapered section: After the optical fiber enters the second cleaning section 402, the debris generated during the first cleaning is first removed by the front cleaning ring 40201 through the nozzle 40202. Then, the fused tapered section 403 moves in the opposite direction (away from the discharge box 2), stretching the inlet ring cavity 40203 and the outlet ring cavity 40204. Fresh cleaning solution from the external cleaning solution storage device is drawn into the inlet ring cavity 40203 through the one-way inlet pressure valve. At the same time, the spray head 40205 above sprays and cleans the optical fiber under the action of the pressurized pump. The return head 40206 below transfers the contaminated cleaning solution to the outlet ring cavity 40204 through the water pump, and then discharges it through the one-way outlet pressure valve. The rear cleaning ring 40201 circulates hot air through the nozzle 40202 to dry the optical fiber. During this process, the extension and retraction of the molten tapered section 403 is directly linked with the intake and discharge of the cleaning fluid, achieving dynamic cleaning, and all workstations simultaneously complete the above-mentioned secondary cleaning and drying. S5. Fused Tapering, Multi-Station Synchronous Heating Rotation and Differential Stretching: The dried optical fiber enters the fused tapering section 403. Positioning components 40304 in each station move horizontally along the slide groove to lock the optical fiber. The central fused fiber 40305 (using laser heating and equipped with a PID temperature control closed-loop system) uniformly heats the optical fiber to a molten state along the circumference, while the rotating ring 40302 drives the optical fiber to rotate, ensuring uniform heating. Subsequently, the two sets of mounting rings 40301 move at different speeds on the slide groove 101 (generating…). (Speed ​​difference) axial tapering of the fused optical fiber, the tapering angle being adjustable by controlling the moving trajectory; during tapering, the inner sliding sleeve 40307 and the outer telescopic sleeve 40308 slide relative to each other, exposing the second nozzle 40306 in the annular groove, the second nozzle 40306 being connected to an external coating storage device and a protective gas source, synchronously spraying protective gas into the tapering area to prevent oxidation, and spraying coating to form a protective layer after tapering is completed; the fused tapering sections 403 of multiple stations simultaneously perform the above differential stretching action to ensure that the tapering parameters of each optical fiber are consistent. S6. Cutting and finished product extraction are completed and reset simultaneously at multiple stations. After the fusion tapering is completed, the second cutting component 40107 and the first cutting component cut the optical fiber. At the same time, the positioning airbag ring 40105 in the fiber threading ring 40102 is inflated to clamp the optical fiber and prevent it from slipping. The feeding structure 5 continues to move and completely leads the finished optical fiber out of the fusion tapering section 403. The locking buckles 303 at each station adjust the tension of the remaining optical fiber by telescoping to prepare for the next round of tapering. All feeding structures 5 and the fusion tapering section 403 are reset. The liquid inlet ring cavity 40203 and the liquid outlet ring cavity 40204 in the second cleaning section 402 are compressed again to discharge the waste liquid, completing a complete work cycle. The simultaneous operation of multiple stations greatly improves the overall production efficiency of the machine.
