Description

Technical Field

[0001] This invention belongs to the technical field of stripping the outer sheath of large-core optical fibers, specifically, it relates to a stripping device for large-core optical fibers. Background Technology

[0002] Large-core optical fibers have large core / cladding diameters, and some special large-core optical fibers (such as power transmission fibers) have small refractive index differences between the core and cladding, resulting in relatively low mechanical strength. Existing stripping tools have poor blade precision adaptability, easily leading to over-cutting during operation, causing cladding scratches, core edge chipping, or microcracks. If the stripping force is not properly controlled, it can also cause uneven axial stress on the fiber, triggering latent internal stress damage, which can easily lead to breakage and a sharp increase in transmission loss during subsequent coupling or use. The adhesion between the outer sheath (coating layer) and cladding of some large-core optical fibers is strong, and conventional mechanical stripping can easily leave coating residue. If forcibly peeled off, it can also tear the cladding surface, damaging the optical transmission interface of the fiber.

[0003] Manual stripping relies on experience, making it difficult to precisely control the stripping length and end-face flatness. After stripping large-core fiber, problems such as large stripping length deviations, end-face tilting, and edge burrs often occur, failing to meet the requirements of high-precision optical coupling. Existing semi-automatic stripping equipment is mostly designed for small-core fiber, and the clamping stability for large-core fiber is insufficient. During the stripping process, fiber slippage and rotation can easily occur, causing the stripped surface to be non-perpendicular to the fiber axis, affecting subsequent end-face polishing and coupling efficiency. Summary of the Invention

[0004] This invention provides a large-core-diameter optical fiber stripping device to improve stripping accuracy and adaptability, reduce maintenance costs, effectively soften the coating layer to reduce resistance, improve stripping edge flatness, protect the fiber core, and improve stripping consistency and efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A large-core-diameter optical fiber stripping device includes a rotating mechanism, a stripping blade, and a heating device arranged sequentially and spaced apart along the length of the optical fiber, all mounted on a machine body. One end of the optical fiber passes through the rotating mechanism and the stripping blade in sequence and extends to the end of the heating device away from the stripping blade. The stripping blade is connected to a longitudinal driving mechanism, which drives the stripping blade to move along the length of the optical fiber.

[0006] A further technical solution is that the heating device includes an adapter bracket installed on the stripping machine, a heating module installed on the adapter bracket, and a heating channel with its upper end in an open state opened on the heating module. The heating channel extends along the length direction of the optical fiber, and one end of the optical fiber extends from one end of the heating channel to the other end of the heating channel.

[0007] A further technical solution is that the heating module includes two electric heating elements symmetrically arranged on both sides of the optical fiber, a heating channel is formed between the two electric heating elements, each electric heating element extends along the length of the optical fiber, one end of the two electric heating elements is connected by a conductive sheet, a connecting wing is constructed at the end of each electric heating element away from the conductive sheet, and the two connecting wing are connected to the positive and negative electrodes respectively; the distance between the two electric heating elements decreases from top to bottom, and a support base is provided at the ends of the two electric heating elements that are far from each other, each electric heating element and each support base are mounted on a heat sink, and the heat sink is detachably connected to the adapter bracket.

[0008] A further technical solution is that the heat sink has a U-shaped cross-section and forms a U-shaped groove with the upper end in an open state. The lower part of each support and each electric heating element are assembled in the U-shaped groove, and the lower end of the support and the lower end of the electric heating element abut against the end face of the bottom of the U-shaped groove. Multiple limiting protrusions are constructed on the heat sink and on the end face of the bottom of the U-shaped groove. The multiple limiting protrusions are spaced apart along the length direction of the optical fiber, and the two electric heating elements abut against the root of each limiting protrusion on both sides.

[0009] A further technical solution is that the stripping tool includes an opening and closing drive mechanism that is slidably mounted vertically on the mounting base, and a double-blade stripping mechanism is provided on the opening and closing drive mechanism. The double-blade stripping mechanism has two oppositely arranged blade holders, and the two blade holders are connected to the output end of the opening and closing drive mechanism. A cam-type lifting mechanism for driving the vertical movement of the opening and closing drive mechanism is provided between the mounting base and the opening and closing drive mechanism.

[0010] A further technical solution is that the dual-blade stripping mechanism includes two blade groups installed vertically at intervals between two blade holders. The lower ends of the two blade holders are supported by a support assembly, which is connected to a cam-type lifting mechanism. Mounting blocks are detachably connected to the close ends of the two blade holders, and the two blade groups are installed vertically at intervals between the two mounting blocks.

[0011] A further technical solution is that each of the blade groups includes two stripping blades arranged opposite each other, and the two stripping blades are connected to two mounting blocks in a one-to-one correspondence; a V-shaped cutting edge is formed at the stripping end of the stripping blade, and when the two stripping blades of the blade group cut the outer sheath of the optical fiber, the two V-shaped cutting edges form a quadrilateral stripping opening; a positioning post and a positioning hole are respectively constructed at the close ends of the two mounting blocks, and the positioning post and the positioning hole are aligned.

[0012] A further technical solution is that the cam-type lifting mechanism includes a transmission column installed at the lower middle position of the opening and closing drive mechanism, a drive cam is provided at the lower end of the transmission column, the drive cam is connected to the output shaft of the servo motor, the servo motor is mounted on the mounting base, and a rotary encoder for monitoring the rotation angle of the output shaft of the servo motor is mounted on the mounting base.

[0013] A further technical solution is that the rotating mechanism includes a mounting frame detachably connected to the mounting base, a rotating actuation component is mounted on the mounting frame, an adapter is connected to the output end of the rotating actuation component, a receiving platform is mounted on the end of the adapter away from the mounting frame, and multiple pressure caps are spaced apart on the receiving platform along the length direction of the optical fiber.

[0014] A further technical solution is that the rotary actuator includes a first gear, a second gear, and a third gear that mesh sequentially upwards in a vertical direction. The first gear, the second gear, and the third gear are all rotatably connected to the mounting frame. A cover is installed on the mounting frame at the location of the first gear, the second gear, and the third gear. A third drive motor is installed on the mounting frame. The output shaft of the third drive motor is coaxially connected to the first gear. A first wire-passing notch is provided on the third gear. A second wire-passing notch communicating with the first wire-passing notch is provided on the adapter.

[0015] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned structure, are as follows: The heating device of this invention pre-softens the fiber coating uniformly, reducing the adhesion between the coating and cladding. This eliminates the need for excessive force during the stripping process, fundamentally solving the problems of cladding scratches, core edge breakage, and latent stress damage caused by uneven axial stress due to excessive cutting in traditional mechanical stripping. This ensures the structural integrity of the fiber core and cladding. The rotating mechanism drives the fiber to rotate smoothly, coordinating with the circumferential cutting action of the stripping blade to achieve a ring-shaped cut of the coating. This avoids the defects of coating tearing and residue in traditional manual operations, ensuring the cleanliness of the optical transmission interface and reducing subsequent transmission loss.

[0016] The longitudinal drive mechanism of this invention drives the stripping cutter to move at a constant speed along the fiber length. Combined with the precise speed control of the rotation mechanism, it achieves quantitative control of the stripping length, ensuring that the stripping length of each fiber is uniform. The stripping cutter and the rotation mechanism work together to ensure that the stripping surface is always perpendicular to the fiber axis, solving problems such as end face tilt and edge burrs. This provides a high-precision foundation for subsequent end face grinding and optical coupling, improving coupling efficiency and stability.

[0017] The coordinated operation of the longitudinal drive mechanism, rotation mechanism, and heating device forms an automated process for heating and softening, ring cutting, and axial stripping. This eliminates the need for repeated manual adjustments of force and angle, significantly reducing the time required to strip a single optical fiber and solving the problems of repetitive operations and low efficiency associated with traditional tools. The standardized operating mode is unaffected by human experience or ambient temperature, avoiding quality fluctuations caused by human error and greatly improving the yield rate for mass production, thus adapting to the needs of large-scale production.

[0018] In summary, this invention improves stripping accuracy and adaptability, reduces maintenance costs, effectively softens the coating layer to reduce resistance, improves stripping edge flatness, protects the fiber core, and enhances stripping consistency and efficiency.

Detailed Implementation

[0022] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0023] This invention discloses a large-core-diameter optical fiber stripping device, such as... Figures 1-25 As shown, the device includes a rotating mechanism 900, a stripping blade, and a heating device, which are installed on the body and arranged sequentially at intervals along the length of the optical fiber 300. One end of the optical fiber 300 passes through the rotating mechanism 900 and the stripping blade in sequence and extends to the end of the heating device away from the stripping blade. The stripping blade is connected to a longitudinal drive mechanism 500, which is used to drive the stripping blade to move along the length of the optical fiber 300.

[0024] The heating device of this invention pre-softens the coating layer at the end of the optical fiber 300 uniformly, reducing the adhesion between the coating layer and the cladding. This eliminates the need for excessive force during the stripping process, fundamentally solving the problems of cladding scratches, core edge breakage, and latent stress damage caused by uneven axial force due to excessive cutting in traditional mechanical stripping, thus ensuring the structural integrity of the fiber core and cladding. The rotating mechanism 900 drives the optical fiber 300 to rotate smoothly, cooperating with the circumferential cutting action of the stripping tool to achieve a ring-shaped cut of the coating layer. This avoids the defects of coating layer tearing and residue in traditional manual operation, ensuring the cleanliness of the optical transmission interface and reducing subsequent transmission loss.

[0025] The longitudinal drive mechanism 500 of this invention drives the stripping cutter to move at a uniform speed along the length of the optical fiber 300. Combined with the precise speed control of the rotating mechanism 900, it achieves quantitative control of the stripping length, ensuring that the stripping length of each optical fiber 300 is uniform. The stripping cutter and the rotating mechanism 900 work together to ensure that the stripping surface is always perpendicular to the axis of the optical fiber 300, solving problems such as end face tilt and edge burrs. This provides a high-precision foundation for subsequent end face grinding and optical coupling, improving coupling efficiency and stability.

[0026] The coordinated operation of the longitudinal drive mechanism 500, the rotating mechanism 900, and the heating device forms an automated process for heating and softening, ring cutting, and axial stripping. This eliminates the need for repeated manual adjustments of force and angle, significantly reducing the time required to strip a single 300mm fiber and solving the problems of repetitive operations and low efficiency associated with traditional tools. The standardized operating mode is unaffected by human experience or ambient temperature, avoiding quality fluctuations caused by human error and greatly improving the yield rate for mass production, thus adapting to the needs of large-scale production.

[0027] In summary, this invention improves stripping accuracy and adaptability, reduces maintenance costs, effectively softens the coating layer to reduce resistance, improves stripping edge flatness, protects the fiber core, and enhances stripping consistency and efficiency.

[0028] As a preferred embodiment of the present invention, such as Figure 1-7 As shown, the heating device includes an adapter bracket 201 mounted on the stripper 100, a heating module 200 mounted on the adapter bracket 201, a heating channel 218 opened on the heating module 200, the upper end of the heating channel 218 is in an open state, and the heating channel 218 extends along the length direction of the optical fiber 300, with one end of the optical fiber 300 extending from one end of the heating channel 218 to the other end of the heating channel 218.

[0029] This embodiment is highly adaptable and can be installed on the fiber stripper 100. The heating channel 218, extending along the length of the fiber 300, ensures the end of the fiber 300 is fully heated, effectively softening the coating layer, reducing stripping resistance, and preventing tearing or residue of the coating. The open upper end of the heating channel 218 facilitates the removal of the stripped outer sheath of the fiber 300. Combined with uniform heating, this improves the flatness of the stripped area, reduces defects such as burrs and bevels, and ensures optimal performance in subsequent applications such as optical coupling and sensing. Stripping after heating requires minimal force, preventing scratches and damage to the fiber core and cladding due to improper stress, thus protecting the optical and mechanical properties of the fiber 300. Furthermore, the standardized heating method is unaffected by ambient temperature or manual operation, improving stripping consistency, adapting to large-scale production, and increasing operational efficiency.

[0030] As a preferred embodiment of the present invention, such as Figure 7 As shown, the heating module 200 includes two electric heating elements 213 symmetrically arranged on both sides of the optical fiber 300. A heating channel 218 is formed between the two electric heating elements 213, and each electric heating element 213 extends along the length of the optical fiber 300. One end of the two electric heating elements 213 is connected by a conductive sheet 214. A connecting wing 215 is constructed at the end of each electric heating element 213 away from the conductive sheet 214, and the two connecting wing 215 are connected to the positive and negative electrodes respectively.

[0031] In this embodiment, two electric heating elements 213 are symmetrically distributed on both sides of the optical fiber 300, forming a wraparound heating channel 218. This allows for simultaneous heat conduction from both sides of the optical fiber 300, ensuring uniform circumferential heating of the coating layer. This avoids uneven peeling resistance caused by insufficient softening in certain areas, resulting in more thorough overall softening of the coating layer and laying the foundation for complete peeling. The electric heating elements 213 extend along the length of the optical fiber 300, consistent with the extension direction of the heating channel 218. This allows for full-length coverage heating of the area to be peeled at the end of the optical fiber 300, precisely targeting the area of ​​the coating layer that needs to be peeled, avoiding heat waste, and ensuring that the heating depth matches the coating layer peeling requirements.

[0032] Two electric heating elements 213 are connected at one end via a conductive sheet 214, and the other end is connected to the positive and negative poles via a connecting wing 215, forming a stable series circuit. This ensures smooth current conduction and stable and controllable heating power, allowing for precise adjustment of the heating temperature according to the characteristics of the coating material. This avoids overheating damage to the optical fiber 300 or insufficient heating affecting the softening effect. The symmetrical design of the electric heating elements 213 makes the heating channel 218 regular in shape and compact in overall structure. It can be efficiently integrated with other components of the device and adapts to the heating requirements of large-core optical fibers 300 of different specifications, improving the versatility and practicality of the device.

[0033] As a preferred embodiment of the present invention, such as Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the distance between the two electric heating elements 213 decreases from top to bottom. Support seats are provided at the ends of the two electric heating elements 213 that are far apart from each other. Each electric heating element 213 and each support seat are mounted on a heat sink 202. The heat sink 202 is detachably connected to the adapter bracket 201.

[0034] The support base includes a vertically arranged support body 209 extending along the length of the optical fiber 300. A limiting body 210 is provided at the upper end of the support body 209, and the limiting body 210 is detachably connected to the heat sink 202. A limiting edge 211 is formed at the connection between the support body 209 and the limiting body 210, and the upper end of the electric heating element 213 is engaged with the limiting edge 211 on the corresponding side.

[0035] The heat sink 202 of this embodiment has a U-shaped cross-section, forming a U-shaped groove 203 with its upper end open. The lower part of each support and each electric heating element 213 are assembled in the U-shaped groove 203, and the lower end of the support and the lower end of the electric heating element 213 abut against the end face of the bottom of the U-shaped groove 203. A plurality of limiting protrusions 204 are constructed on the heat sink 202 and on the end face of the bottom of the U-shaped groove 203. These limiting protrusions 204 are spaced apart along the length of the optical fiber 300, and two electric heating elements 213 abut against the root of each limiting protrusion 204 on both sides.

[0036] In this embodiment, the spacing between the two electric heating elements 213 decreases from top to bottom, forming a heating channel 218 that is wider at the top and narrower at the bottom. This allows heat to be concentrated in the core area of ​​the optical fiber 300, reducing heat loss and enabling the coating layer to quickly absorb heat and soften evenly, significantly improving heating efficiency and shortening pretreatment time. The support base secures the upper end of the electric heating element 213 by limiting it along the 211. The bottom of the U-shaped groove 203 of the heat sink 202, along with the limiting protrusion 204, abuts against the lower end and both sides of the electric heating element 213, thus limiting the position of the electric heating element 213 from multiple directions. This prevents the electric heating element 213 from shifting due to vibration or force during heating, ensuring the stability of the heating channel 218 and a high degree of consistency in heating effect for different batches of optical fibers 300. The design of the heating channel 218, wider at the top and narrower at the bottom, is suitable for large-core optical fibers 300 of different diameters. After the optical fiber 300 is placed, it can naturally fit the narrow-spacing area at the bottom of the heating element, ensuring that optical fibers 300 of different radial lengths are fully heated, thus improving the versatility of the device.

[0037] The electric heating element 213, support base, and heat sink 202 are modularly assembled, and the heat sink 202 is detachably connected to the adapter bracket 201, making installation and disassembly convenient. Each component is fixed by a mechanical structure, ensuring a stable connection that is not easily loosened during long-term use. Subsequent maintenance and replacement of the electric heating element 213 or support base are simple, reducing maintenance costs. The U-shaped heat sink 202 not only provides a mounting carrier for each component but also quickly conducts excess heat, preventing localized overheating that could damage the fiber core or cladding of the optical fiber 300. It also prevents the heating module 200 from aging due to overheating, extending the lifespan of the device.

[0038] As a preferred embodiment of the present invention, such as Figures 3-7 As shown, a first base 206 and a second base 207 are respectively constructed at both ends of the heat sink 202. The first base 206 is detachably connected to the adapter bracket 201, and a protective cover 212 is detachably connected to the second base 207. The end of the optical fiber 300 is close to or in contact with the protective cover 212. Connecting holes 208 are symmetrically constructed on both sides of the second base 207, and conductive components are connected to each connecting hole 208. Each conductive component is electrically connected to a corresponding connecting wing 215. Conductive plates 216 are detachably connected to both sides of the heat sink 202. Each conductive plate 216 is electrically connected to the connecting wing 215 via a corresponding conductive component, and a conductive ear 217 is installed on each conductive plate 216. Multiple side limiting blocks 205 are constructed on both sides of the heat sink 202. Limiting openings are opened on each conductive plate 216 at positions corresponding to each side limiting block 205, and the side limiting blocks 205 are assembled into the corresponding limiting openings.

[0039] In this embodiment, the first base 206 is detachably connected to the adapter bracket 201, facilitating the assembly, debugging, and subsequent maintenance of the entire device and the stripper 100. The second base 207 is detachably connected to the protective cover 212, making it easy to clean residual impurities in the heating channel 218 or replace the protective cover 212. The conductive plate 216 is detachably connected to the heat sink 202, and with the precise assembly of the side limiting block 205 and the limiting port, it simplifies the disassembly and assembly process of the conductive plate 216, and enables quick maintenance or replacement of conductive components, reducing maintenance costs and downtime. The protective cover 212 is positioned near or in contact with the end of the optical fiber 300, which can block debris and volatiles generated by the softening of the coating layer during heating from splashing, avoiding contamination of other parts of the equipment or affecting the operating environment; at the same time, it can prevent operators from accidentally touching the high-temperature end of the optical fiber 300 or the electric heating element 213, improving operational safety, and can also reduce the entry of external dust and other impurities into the heating channel 218, ensuring a clean heating environment and indirectly improving the stripping quality.

[0040] The second base 207 has symmetrically arranged connection holes 208 on both sides, and the conductive components are precisely aligned with the connecting wing 215 and conductive plate 216 to form a symmetrical and regular circuit connection structure. This ensures smooth current conduction and stable contact resistance, avoiding heating power fluctuations caused by poor contact. The conductive ears 217 are designed for easy connection to an external power source. Combined with the stable circuit structure, heating parameters can be precisely adjusted according to the coating material and thickness to achieve controllable heating. This avoids overheating damage to the optical fiber 300 and ensures a softening effect. The side limiting blocks 205 on both sides of the heat sink 202 are fitted with the limiting ports of the conductive plate 216 to precisely limit the installation position of the conductive plate 216. This prevents the conductive plate 216 from shifting due to vibration or current surges during use, ensuring a stable electrical connection between the conductive components and the connecting wing 215. The symmetrical design and detachable connection of each component make the overall structure more stable and less prone to loosening over long-term use. This ensures the stability and consistency of the heating process, thereby improving the reliability of the optical fiber 300 stripping quality.

[0041] As a preferred embodiment of the present invention, such as Figures 8-19 As shown, the stripping tool includes an opening and closing drive mechanism 600 that is slidably mounted vertically on the mounting base 400. A dual-blade stripping mechanism 700 is provided on the opening and closing drive mechanism 600. This dual-blade stripping mechanism 700 has two opposing blade holders 701, which are drively connected to the output end of the opening and closing drive mechanism 600 and driven to perform opening and closing movements. A cam-type lifting mechanism 800 is provided between the mounting base 400 and the opening and closing drive mechanism 600, and the cam-type lifting mechanism 800 is used to drive the opening and closing drive mechanism 600 to move vertically.

[0042] This embodiment employs a combination of a cam-type lifting mechanism 800 and an opening / closing drive mechanism 600 that slides vertically, converting the mechanical rotation of the cam into a smooth vertical displacement of the opening / closing drive mechanism 600. Compared to the traditional fixed / coarse adjustment cutting edge depth design for large-core diameter optical fibers, this structure can precisely adjust the vertical height of the dual-blade stripping mechanism 700, ensuring that the stripping blade 705 only cuts into the coating layer without touching the cladding and core wire. This completely solves the core defects of insufficient cutting depth leading to incomplete stripping, excessive cutting depth causing cladding scratches, and micro-cracks in the core layer, and is particularly suitable for the characteristics of large-core diameter optical fiber 300, which has a thick coating and strong cladding rigidity.

[0043] The two blade holders 701 are synchronously driven through the output of the opening and closing drive mechanism 600, ensuring that their relative motion trajectories are strictly symmetrical. This avoids blade head deviation caused by traditional manual operation or simple machinery, eliminates the problems of oblique stripping and off-center stripping when stripping the ends of large-core fiber 300, and ensures that the stripped end face is flat, providing a precise foundation for subsequent fusion splicing and connection.

[0044] This embodiment achieves fully mechanical control of vertical height adjustment, blade holder 701 opening and closing, and stripping action during the stripping process through the coordinated linkage of the opening and closing drive mechanism 600 and the cam-type lifting mechanism 800. Compared with the traditional method that relies on the operator's experience to control the force and angle, it completely avoids the stripping quality fluctuations caused by hand tremors and fatigue, ensuring that when batch processing large-core diameter optical fibers 300, the stripping depth, end face flatness, and stripping length of each optical fiber 300 are consistent, greatly improving the yield of batch operations.

[0045] In summary, this embodiment can effectively improve the peeling accuracy and adaptability, reduce maintenance costs, replace manual operation, and avoid human error.

[0046] As a preferred embodiment of the present invention, such as Figures 8-10 As shown, the mounting base 400 is connected to the longitudinal drive mechanism 500 for driving the mounting base 400 to move along the length direction of the optical fiber 300. The longitudinal drive mechanism 500 includes a first drive motor 501, which is mounted on the upper end surface of the bottom wall of the stripping machine. A transmission screw 502 is coaxially mounted on the output shaft of the first drive motor 501. The transmission screw 502 extends along the length direction of the optical fiber 300 and is threadedly connected to a transmission sleeve 503. The transmission sleeve 503 is detachably connected to the mounting base 400. The mounting base 400 is slidably mounted on a longitudinal slide rail 506, which is mounted on the upper end surface of the bottom wall of the stripping machine. A first position sensor 504 and a second position sensor 505 are installed at intervals along the length direction of the optical fiber 300 on the upper end surface of the bottom wall of the stripping machine.

[0047] This embodiment employs a threaded transmission combination of a first drive motor 501, a transmission screw 502, and a transmission sleeve 503. This precisely converts the rotational motion of the first drive motor 501 into the linear motion of the mounting base 400. The small transmission gap and high rigidity ensure that the mounting base 400 drives the dual-blade stripping mechanism 700 to move smoothly and uniformly along the length of the optical fiber 300. Combined with the longitudinal slide rail 506 limiting the trajectory of the mounting base 400, this completely avoids the lateral offset and torsion problems common in traditional manual operation or simple machinery. This ensures that the dual-blade stripping mechanism 700 always moves along the axial direction of the large-diameter optical fiber 300, structurally eliminating defects such as uneven end faces and uneven core wire exposure caused by oblique or off-center stripping. This design is well-suited to the characteristics of the large-diameter optical fiber 300, which has high cladding rigidity and high requirements for the stripping trajectory.

[0048] A first position sensor 504 and a second position sensor 505, installed at intervals along the length of the optical fiber 300, correspond to the start and end points of the stripping operation, respectively. When the mounting base 400 moves the dual-blade stripping mechanism 700 to the sensing range, a stop or reversal signal can be automatically triggered to precisely limit the maximum stroke of the longitudinal movement. This prevents the dual-blade stripping mechanism 700 from exceeding the target stripping area due to over-driving, thus avoiding damage to non-operating sections of the large-core optical fiber 300 (such as the complete cladding outside the end) or equipment components. This is particularly suitable for the precise requirements of stripping the end of large-core optical fiber 300, where only a specific length of the end face needs to be processed. The precise triggering mechanism of the first position sensor 504 and the second position sensor 505 makes the start and end positions of the stripping operation quantifiable and repeatable. Compared to traditional positioning methods that rely on manual marking or experience-based judgment, this method completely avoids stripping length fluctuations caused by human error, ensuring that the stripping length of large-core diameter fiber 300 ends is completely consistent across different batches. This provides a standardized end-face foundation for subsequent fusion splicing and other processes, significantly improving the yield of batch operations. By adjusting the installation spacing between the first position sensor 504 and the second position sensor 505, the stripping length requirements of different large-core diameter fiber 300 ends can be quickly adapted. Without replacing the core drive component, multi-specification adaptation can be achieved, solving the shortcomings of traditional cutters with fixed stripping lengths and poor adaptability, thus improving the tool's versatility.

[0049] As a preferred embodiment of the present invention, such as Figures 11-15 As shown, the opening and closing drive mechanism 600 includes a transmission component that is connected to the output end of the drive component. The transmission component is connected to the vertical drive mechanism, and the vertical drive mechanism is slidably connected to the vertical seat 401 of the mounting base 400 in a vertical direction. The transmission component is connected to the double-blade stripping mechanism 700.

[0050] The transmission assembly includes a mounting base 609, with vertical slide rails 615 on both sides. The mounting base 609 is slidably connected to the vertical seat body 401 of the mounting base 400 via the vertical slide rails 615. A clearance notch 614 extending downward in the vertical direction is provided in the middle of the upper end of the mounting base 609 to allow the optical fiber 300 to pass through without interference. A transmission plate 607 is rotatably connected to the mounting base 609. The transmission plate 607 is connected to the drive assembly, and the double-blade stripping mechanism 700 is slidably mounted on the mounting base 609 and is connected to the transmission plate 607 for transmission.

[0051] In this embodiment, a mounting groove 610 is constructed on the mounting base 609, and a protective plate 611 is installed on the outside of the mounting groove 610 to protect the components inside the mounting groove 610. A transmission plate 607 is assembled inside the mounting groove 610. Two strip-shaped holes 613 are opened on the mounting base 609 at a lateral interval along the stripping machine. Each strip-shaped hole 613 extends laterally along the stripping machine and connects to the mounting groove 610. Two arc-shaped holes 608 are symmetrically opened on the transmission plate 607. Each arc-shaped hole 608 extends circumferentially along the rotation axis of the transmission plate 607, and the two arc-shaped holes 608 correspond one-to-one with the two strip-shaped holes 613. Two blade holders 701 are symmetrically arranged on the mounting base 609, and these two blade holders 701 are slidably assembled on the transverse slide rail 702 of the mounting base 609 along the transverse direction of the stripping machine. A drive pin 703 is installed on each tool holder 701, which extends into the part where the arc-shaped hole 608 and the strip-shaped hole 613 intersect (overlap).

[0052] The drive assembly in this embodiment includes a second drive motor 601 mounted on a mounting base 609. A transmission plate 607 is connected to a transmission shaft 603, and the transmission shaft 603 is rotatably connected to a support base 612. The support base 612 is connected to the U-shaped seat 709 described below. A drive pulley 602 is mounted on the output shaft of the second drive motor 601, and a driven pulley 604 is mounted on the transmission shaft 603. The drive pulley 602 and the driven pulley 604 are connected by a synchronous belt 605. A third position sensor 606 is provided on the mounting base 609, above the output shaft of the second drive motor 601 or above the drive pulley 602. The third position sensor 606 is used to monitor the rotation angle of the output shaft of the second drive motor 601 or the drive pulley 602, so as to control the opening and closing degree of the two tool holders 701.

[0053] In this embodiment, the arc-shaped hole 608 of the transmission plate 607 and the strip-shaped hole 613 of the mounting base 609 intersect, and the transmission pin 703 passes through the intersection. When the second drive motor 601 drives the transmission plate 607 to rotate, the arc-shaped hole 608 drives the two cutter holders 701 to slide synchronously forward or backward along the transverse slide rail 702 through the transmission pin 703. This structure ensures that the opening and closing trajectory of the cutter holders 701 is strictly symmetrical, ensuring that the two cutter groups below always remain centered, avoiding problems such as uneven cutting depth and stripping range deviation caused by unilateral offset, and ensuring consistent operation quality of the same batch of optical fibers 300. The third position sensor 606 monitors the rotation angle of the output shaft of the second drive motor 601 or the active pulley 602 in real time and accurately converts it into the opening and closing distance of the cutter holders 701. The operator can preset the opening and closing parameters according to the width and sheath thickness of the optical fiber 300, which avoids the cutter head idle stroke caused by excessive opening and closing, and also prevents incomplete sheath cutting or core wire compression damage caused by insufficient opening and closing, realizing quantitative control and repeatable precision of the opening and closing degree.

[0054] In this embodiment, the drive assembly drives the transmission shaft 603 to rotate via a synchronous belt 605, resulting in smooth transmission without rigid impact. Combined with the progressive drive of the arc-shaped hole 608, the opening and closing speed of the cutter holder 701 is uniform and controllable. Compared to manual or simple mechanical opening and closing methods, this avoids surface compression and core wire scratches caused by the instantaneous clamping of the cutter head. It is especially suitable for multi-core optical fibers 300, reducing hidden damage caused by uneven stress on individual core wires. The clearance notch 614 at the upper end of the mounting base 609 extends vertically, providing a dedicated channel for the optical fiber 300, ensuring that the optical fiber 300 does not collide or rub against other mechanisms during the opening, closing, vertical lifting, and longitudinal movement of the cutter holder 701. This avoids displacement and surface scratches of the optical fiber 300 due to structural interference, and is especially suitable for the unsupported state of the middle section of the optical fiber 300 during non-end stripping operations, ensuring the structural integrity of the optical fiber 300 throughout the entire operation.

[0055] In this embodiment, the drive assembly, transmission assembly, and tool holder 701 are all modularly designed. Easily damaged components such as the synchronous belt 605, transmission plate 607, and transmission pin 703 can be individually disassembled and replaced. The mounting slot 610 of the mounting base 609 provides a stable assembly space for the transmission plate 607 and facilitates daily cleaning and inspection. Compared to an integrated structure, this significantly reduces maintenance difficulty and equipment downtime. The transmission plate 607 is mounted within the mounting slot 610, and the drive assembly is integrated into one side of the mounting base 609. The overall structure is compact and highly integrated, adaptable to the limited space inside the stripped-out machine body. Simultaneously, the transverse slide rail 702 limits the movement direction of the tool holder 701, preventing opening and closing actions from occupying additional space, ensuring no conflict with the movement trajectories of other components, and optimizing the overall machine space layout.

[0056] As a preferred embodiment of the present invention, such as Figures 17-19 As shown, the dual-blade stripping mechanism 700 includes two blade sets vertically spaced between two blade holders 701. The lower ends of the two blade holders 701 are supported by a support assembly, which is connected to a cam-type lifting mechanism 800. Mounting blocks 704 are detachably connected to the near ends of the two blade holders 701, and the two blade sets are vertically spaced between the two mounting blocks 704. Each blade set includes two oppositely arranged stripping heads 705, which are connected one-to-one with the two mounting blocks 704. A V-shaped cutting edge is formed at the stripping end of the stripping head 705. When the two stripping heads 705 of the blade set cut the outer sheath of the optical fiber 300, the two V-shaped cutting edges form a quadrilateral stripping opening. Positioning posts 706 and positioning holes 707 are respectively constructed at the near ends of the two mounting blocks 704, with the positioning posts 706 and positioning holes 707 aligned.

[0057] In this embodiment, the stripping head 705 adopts a V-shaped cutting edge. When the two stripping heads 705 are closed, they form a quadrilateral stripping opening. Compared with the traditional single cutting edge or circular clamping structure, this allows for full-circumferential wrapping cutting of the end of the large-core fiber 300. The quadrilateral structure can precisely fit the outer circumference of the fiber 300, ensuring uniform contact between the cutting edge and the coating layer, avoiding excessively deep or shallow cutting in certain areas. This completely solves the core defects of traditional tools, such as insufficient cutting depth leading to incomplete stripping, excessive cutting depth causing cladding scratches, and micro-cracks in the core layer. At the same time, the uniform contact area can distribute the cutting pressure, adapting to the high rigidity of the cladding of the large-core fiber 300, and preventing fiber 300 displacement caused by excessive local force on the cutting edge.

[0058] The positioning posts 706 and positioning holes 707 of the two mounting blocks 704 are precisely aligned at their proximal ends. When the blade holder 701 is closed, the relative positions of the two blade groups are forcibly calibrated, ensuring that the stripping blades 705 of the upper and lower blade groups are always symmetrically distributed along the axis of the optical fiber 300. Compared with the traditional non-positioning design, this completely eliminates problems such as oblique stripping and off-center stripping caused by blade head skew or misalignment, ensuring that the stripped end face is flat and vertical, providing a standardized end face foundation for subsequent fusion splicing and connection processes, and significantly reducing fusion loss. One blade group is used to cut the outer sheath at a predetermined position of the optical fiber 300, and when the optical fiber 300 is driven to rotate at a predetermined angle, the outer sheath at that position of the optical fiber 300 is cut in a ring. The other blade group, in conjunction with the longitudinal drive mechanism 500, is used to strip the outer sheath of the optical fiber 300.

[0059] As a preferred embodiment of the present invention, such as Figure 19 As shown, the support assembly includes a U-shaped seat 709 mounted on the opening and closing drive mechanism 600. Connecting posts 710 are fixedly mounted at both free ends of the U-shaped seat 709. An elastic sleeve 711 is fitted over each connecting post 710, with the upper part of the outer circumferential surface of the elastic sleeve 711 elastically abutting against the lower end of the corresponding cutter holder 701. Limiting protrusions 708 are constructed on the sides of the lower ends of the two cutter holders 701 that are close to each other. When the two cutter holders 701 approach each other to the stripping station, each elastic sleeve 711 elastically abuts against the root of the corresponding limiting protrusion 708.

[0060] In this embodiment, the elastic sleeve 711 elastically abuts against the lower end of the cutter holder 701, compensating for the assembly gap between the cutter holder 701 and the transverse slide rail 702, forming a flexible support. When the cutter holders 701 are driven closer or further apart by the opening and closing drive mechanism 600, the supporting force of the elastic sleeve 711 can always limit the cutter holders 701 to the guide trajectory of the transverse slide rail 702, preventing the cutter holders 701 from tilting left or right or tilting up and down due to gaps, ensuring that the cutter holders 701 move in a pure straight line along the transverse direction. The elastic sleeves 711 below the two cutter holders 701 are symmetrically arranged, providing uniform supporting reaction force, so that the force on the cutter holders 701 is balanced when opening and closing, avoiding trajectory deviation caused by uneven force on one side. This ensures that the stripping cutter head 705 of the cutter assembly is always accurately aligned, preventing problems such as inconsistent cutting depth and stripping range deviation caused by the tilt of the cutter holder 701, and ensuring operational accuracy. The elastic sleeve 711 possesses a certain degree of cushioning performance, absorbing vibrations during the opening and closing of the tool holder 701 and impacts during start-up and stopping, reducing rigid friction between the tool holder 701 and the transverse slide rail 702. Simultaneously, the elastic support prevents localized overload on the transverse slide rail 702 caused by the misalignment of the tool holder 701, reducing the wear rate of both the transverse slide rail 702 and the tool holder 701, and extending the service life of the entire mechanism. The elastic deformation of the elastic sleeve 711 can compensate for machining and assembly errors of the tool holder 701 and the transverse slide rail 702. Even with minor dimensional deviations, the elastic support ensures a good fit between the tool holder 701 and the transverse slide rail 702. This prevents movement jamming and misalignment caused by assembly errors, improving the stability and reliability of the mechanism's operation and reducing the failure rate.

[0061] The limiting protrusions 708 at the lower ends of the two cutter holders 701 cooperate with each other to precisely limit the maximum degree of closure of the cutter holders 701, avoiding excessive driving of the opening and closing drive mechanism 600 and resulting in too small a gap between the cutter heads. This protects the cutting edge of the cutter head from collision damage and also prevents excessive clamping of the optical fiber 300 from causing core wire compression deformation or coating damage, thus structurally strengthening the core wire protection line.

[0062] As a preferred embodiment of the present invention, such as Figure 15 , Figure 16 As shown, the cam-type lifting mechanism 800 includes a transmission column 803 installed at the lower middle position of the opening and closing drive mechanism 600. A drive cam 802 is provided at the lower end of the transmission column 803. The drive cam 802 is connected to the output shaft of the servo motor 801. The servo motor 801 is mounted on the mounting base 400. A rotary encoder 804 for monitoring the rotation angle of the output shaft of the servo motor 801 is installed on the mounting base 400.

[0063] This embodiment employs a combination of a servo motor 801, a drive cam 802, and a transmission column 803. The rotational motion of the servo motor 801 is converted into a smooth vertical displacement of the opening and closing drive mechanism 600 via the drive cam 802. In conjunction with a rotary encoder 804, the rotation angle of the output shaft of the servo motor 801 is monitored in real time, allowing for precise quantification of the vertical lifting height. Compared to the traditional fixed / coarse adjustment cutting edge depth design for large-diameter tools, micron-level adjustment accuracy can be achieved. This ensures the smooth switching between the two tool positions of the dual-tool stripping mechanism 700. The transmission column 803 is installed at the lower center of the opening and closing drive mechanism 600. The drive cam 802 applies a lifting force through the transmission column 803, ensuring uniform force distribution on the opening and closing drive mechanism 600 and preventing tilting or jamming during vertical movement. Compared to the potential for mechanism misalignment caused by unilateral lifting, this centrally stressed design ensures that the two blade groups of the dual-blade stripping mechanism 700 rise and fall synchronously, avoiding alignment deviations of the stripping blade head 705 caused by height differences on both sides. This guarantees a flat stripped end face, providing a precise foundation for subsequent fusion splicing. The cam-type lifting mechanism 800 works in conjunction with the opening and closing drive mechanism 600 and the longitudinal drive mechanism 500, integrating into an automated continuous operation process of positioning → lifting → stripping → lowering → resetting, eliminating the need for manual intervention to adjust the height midway. Compared to the segmented operation mode of semi-automated equipment, this significantly shortens the stripping cycle of a single optical fiber 300, improving overall production efficiency.

[0064] As a preferred embodiment of the present invention, such as Figures 20-25 As shown, the rotating mechanism 900 includes a mounting bracket 901 detachably connected to the mounting base 400. A rotating actuator is mounted on the mounting bracket 901. An adapter 909 is connected to the output end of the rotating actuator. A receiving platform 911 is mounted on the end of the adapter 909 away from the mounting bracket 901. A plurality of pressure caps 912 are spaced apart on the receiving platform 911 along the length of the optical fiber 300. The rotating actuator includes a first gear 903, a second gear 904, and a third gear 905 that mesh vertically upwards in sequence. The first gear 903, the second gear 904, and the third gear 905 are all rotatably connected to the mounting bracket 901. A protective cover 907 is mounted on the mounting bracket 901 at the locations of the first gear 903, the second gear 904, and the third gear 905. A third drive motor 902 is mounted on the mounting bracket 901. The output shaft of the third drive motor 902 is coaxially connected to the first gear 903. A first wire-passing notch 906 is provided on the third gear 905, and a second wire-passing notch 910 communicating with the first wire-passing notch 906 is provided on the adapter 909. A fourth position sensor 913 is mounted on the mounting bracket 901 and located at the first gear 903 to monitor the rotation angle of the first gear 903. A protective shell 908 is provided for the fourth position sensor 913.

[0065] In this embodiment, multiple pressure caps 912 are installed at intervals along the length of the optical fiber 300 on the receiving platform 911, forming a multi-point clamping structure. This structure can stably fix the large-core diameter optical fiber 300 along its entire length, completely solving the problems of insufficient clamping stability, slippage, and rotation of the optical fiber 300 during stripping caused by traditional clamps. The uniform pressure distribution of the multi-point pressure caps 912 avoids localized stress concentration on the optical fiber 300 caused by single-point clamping, preventing latent stress damage to the large-core diameter optical fiber 300 due to clamping and squeezing, and ensuring the structural integrity of the fiber core and cladding. The adapter 909 is directly connected to the output end of the rotary actuator. The receiving platform 911 serves as the bearing reference for the optical fiber 300, and its installation accuracy is highly synchronized with the movement accuracy of the rotary actuator, ensuring that the axis of the optical fiber 300 is completely aligned with the rotation axis after clamping, avoiding problems such as tilting of the stripping surface and uneven cutting depth caused by clamping eccentricity.

[0066] The transmission structure, in which the first gear 903, the second gear 904, and the third gear 905 mesh sequentially in the vertical direction, offers a more stable transmission ratio and greater rigidity compared to single-gear or belt drives. This allows for the smooth transmission of power from the third drive motor 902 to the adapter 909, enabling the fiber optic cable 300 to rotate at a uniform speed. This stable rotational motion, combined with the circumferential cutting of the stripping blade, achieves a uniform annular cut of the coating layer, avoiding defects such as inconsistent cut depth and coating layer tearing caused by speed fluctuations and jamming in traditional rotating equipment, thus improving the flatness of the stripped surface.

[0067] The fourth position sensor 913 monitors the rotation angle of the first gear 903 in real time. Through the gear transmission ratio, it accurately calculates the rotation angle of the optical fiber 300, achieving quantitative control and closed-loop feedback of the rotation angle. This completely solves the problem of inaccurate angle control in traditional manual or simple rotating mechanisms. Precise angle control ensures that the annular cutting trajectory of each optical fiber 300 is completely consistent, avoiding incomplete coating cuts due to insufficient rotation angle or wear of the optical fiber 300 due to excessive angle, thus guaranteeing consistency in batch stripping.

[0068] The first wire-passing notch 906 of the third gear 905 connects with the second wire-passing notch 910 of the adapter 909, forming a dedicated wiring channel. The optical fiber 300 can pass through these two notches and extend to the subsequent stripping and heating mechanisms, completely avoiding the problems of the gear transmission components of the traditional rotating mechanism 900 obstructing the optical fiber 300 and causing friction and collision with the mechanism during wiring. The connection design of the first wire-passing notch 906 and the second wire-passing notch 910 ensures that the optical fiber 300 remains in a non-interference state during rotation, preventing displacement and scratches caused by wiring pulling, and ensuring that the original state of the optical fiber 300 is not damaged before stripping. The dimensions of the first wire-passing notch 906 and the second wire-passing notch 910 are compatible with the diameter specifications of large-core optical fibers 300, while avoiding contact between the optical fiber 300 and components such as gears and the protective cover 907 during rotation. This is especially suitable for the wiring needs of multi-core power transmission optical fibers 300 and coarse-diameter special optical fibers 300, improving the equipment's adaptability to different types of large-core optical fibers 300.
