Description

Technical Field

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

[0002] A fiber optic winding machine is a specialized device for winding optical fibers. With the widespread application of fiber optic technology in communication, sensing, and other fields, its market demand continues to rise. In fiber optic device development and miniaturized optical system integration, it is necessary to wind optical fibers onto fiber optic spools or specific structures according to a specific number of turns and arrangement. The core function of the fiber optic winding machine is to wind optical fibers onto a frame or specific structure according to a specific number of turns and arrangement, thereby helping fiber optic devices (such as fiber optic rings, fiber optic sensors, and fiber optic delay lines) to achieve functions such as optical signal delay, interference, and sensing. The performance of these fiber optic devices is closely related to the quality of fiber winding.

[0003] Chinese patent literature discloses an automatic tension control optical fiber winding machine, including a platform frame on which a pay-off mechanism, guide wheels, tension adjustment components, tension detection mechanism, and take-up mechanism are sequentially arranged. This device can automatically control the tension within a target range, achieving constant optical fiber tension and optical fiber winding. In this design, the optical fiber reels of the pay-off and take-up mechanisms are connected to a motor coupling via shafts matching their inner diameters for transmission. This means that when changing pay-off or take-up optical fiber reels of different diameters, corresponding shafts must be used simultaneously to secure them to the motor coupling. However, with the increasingly widespread application of optical fibers, the specifications of optical fiber reels requiring winding are also increasing. In practice, frequent switching between different specifications of optical fiber reels is often necessary for pay-off and take-up operations. The existing shaft-connected optical fiber reel fixing method is difficult to flexibly adapt to multiple specifications of optical fiber reels, not only increasing the complexity of switching operations but also directly leading to a reduction in optical fiber winding efficiency. Utility Model Content

[0004] Therefore, the purpose of this invention is to overcome the shortcomings of existing fiber optic winding machines that cannot adapt to various specifications of fiber optic reels, and to provide a fiber optic winding machine. This invention uses the radial clamping of a top cone to replace the traditional inner diameter matching of the shaft, thereby achieving flexible adaptation to different specifications of fiber optic reels. It can adapt to fiber optic reels with different inner diameters from large to small, significantly reducing the switching frequency of the shaft and ultimately improving the overall winding efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An optical fiber winding machine includes a frame, a fiber optic reel for feeding and a fiber optic reel for taking up at both ends of the frame, a feeding motor and a take-up motor for driving the fiber optic reel and the fiber optic reel respectively, a fiber arrangement mechanism located between the fiber optic reel and the fiber optic reel, a plurality of guide wheels arranged sequentially on the fiber arrangement mechanism along the fiber forward direction, and a tension adjustment mechanism located between two adjacent guide wheels, and further includes two sets of clamping top cone assemblies for clamping the fiber optic reel and the fiber optic reel respectively. Each clamping cone assembly includes a coaxially arranged coupling, a first cone, a shaft, a second cone, and a cone position adjustment device. The coupling is connected to the output end of the pay-off motor / take-up motor. One end of the shaft is detachably connected to the coupling, and the other end of the shaft is rotatably connected to the frame. The first cone, the second cone, and the cone position adjustment device are sequentially coaxially sleeved on the shaft. The pay-off fiber optic reel / take-up fiber optic reel is sleeved on the shaft and located between the first cone and the second cone.

[0006] The installation steps of the fiber optic reel for pay-off or take-up are as follows: align one side of the fiber optic reel for pay-off or take-up with the axis of the first top cone, then align and tighten the second top cone to the other side of the fiber optic reel for pay-off or take-up, pass the shaft through the mounting hole of the frame from one side, and install the top cone position adjustment device on the other side of the frame. Then, the shaft passes through the second top cone, the fiber optic reel for pay-off or take-up, and the first top cone in sequence, and is finally fixed with the coupling to achieve the clamping of fiber optic reels for pay-off or take-up of different specifications. The advantages of this application are as follows: Each assembled clamping cone assembly includes a coaxial first and second apical cone. After the fiber optic reel for feeding and the fiber optic reel for taking up are fitted onto the shaft, the two apical cones move from both sides of the inner diameter of the fiber optic reel towards the center. By fitting the conical surface of the apical cone with the inner diameter of the fiber optic reel, the fiber optic reel is radially clamped and fixed, no longer relying on a strict dimensional match between the shaft and the inner diameter of the fiber optic reel. The apical cone position adjustment device is connected to the second apical cone and can move along the axial direction of the shaft. For fiber optic reels with different inner diameter specifications, the adjustment device can push the second apical cone closer to or further away from the first apical cone, changing the distance between the two apical cones, thereby adapting to fiber optic reels with different inner diameters from large to small. The shaft and coupling are detachably connected. Although the shaft structure is retained, the core positioning function has been transferred to the apical cone. The shaft only needs to be replaced when facing fiber optic reels of extreme specifications, greatly reducing the switching frequency of the shaft. This application uses the radial clamping of the apical cone to replace the traditional inner diameter matching of the shaft, thereby achieving flexible adaptation to fiber optic reels of different specifications and ultimately improving the overall winding efficiency.

[0007] Furthermore, the first top cone includes an integrally formed cylindrical section and a frustum section, the diameter of which varies from 50mm to 250mm; the structure of the second top cone is the same as that of the first top cone. The diameter variation range of the frustum section determines the range of fiber optic disc inner diameters that the clamping top cone assembly can accommodate. A diameter variation range of 50mm-250mm for the frustum section can accommodate most fiber optic discs, meeting the winding requirements of different fiber optic discs.

[0008] Furthermore, the top cone position adjustment device includes a sliding sleeve fitted on the shaft, an elastic element connected to the sliding sleeve and located between the sliding sleeve and the second top cone, and a tightening screw with one end passing through the sliding sleeve and abutting against the shaft. The tightening screw is threadedly connected to the sliding sleeve. The cooperation between the sliding sleeve and the tightening screw can adjust the fixed position of the sliding sleeve on the shaft, thereby adjusting the clamping position of the second top cone. The elastic element is fitted on the shaft and located between the sliding sleeve and the second top cone. When the top cone clamps the fiber optic disc, the spring will generate elastic deformation, providing a continuous preload force to ensure that the top cone and the inner diameter of the fiber optic disc are tightly fitted, while also counteracting the slight vibrations when the fiber optic disc rotates.

[0009] Furthermore, the elastic element is a spring.

[0010] Furthermore, the other end of the tightening screw is provided with a handle.

[0011] Furthermore, the other end of the shaft is rotatably connected to the frame via a bearing, the outer ring of the bearing is fixed on the frame, and the inner ring of the bearing is slidably connected to the shaft.

[0012] Furthermore, the guide wheel is a ceramic guide wheel, and the distance between the guide wheel and the tension adjustment mechanism is greater than or equal to 10mm. Using ceramic material effectively prevents scratch damage to the fiber optic coating, such as polyimide coatings and UV-curable adhesive coatings; the minimum distance between the guide wheel and the tension adjustment mechanism ensures a straight fiber optic routing path and reduces bending loss.

[0013] Furthermore, the coupling is a cross-slider coupling. Cross-slider couplings can simultaneously compensate for radial misalignment of two shafts, have wear-resistant contact surfaces and good load-bearing capacity, are not prone to slippage or breakage under rated load, and can ensure continuous transmission, making them suitable for low-speed winding requirements such as those described in this application.

[0014] Furthermore, the cable laying mechanism includes a cable laying slide and a lead screw mechanism that drives the cable laying slide to move perpendicular to the optical fiber's forward direction.

[0015] Furthermore, the lead screw mechanism includes a ball screw arranged perpendicular to the direction of optical fiber advance, and a stepper motor for driving the ball screw to rotate, wherein the stepper motor drives the ball screw to rotate through a coupling.

[0016] Furthermore, the tension adjustment mechanism includes a dance wheel and a piezoelectric ceramic actuator that connects to and drives the dance wheel to move up and down.

[0017] Furthermore, the optical fiber winding machine also includes a tension detection mechanism, which includes a tension wheel and a tension sensor connected to the tension wheel. The tension wheel is located between two adjacent guide wheels.

[0018] Furthermore, the distance between the guide wheel and the tension wheel is greater than or equal to 10 mm. This minimum distance ensures a straight fiber optic cable path and reduces bending loss.

[0019] Furthermore, the optical fiber winding machine also includes a length measuring mechanism, which includes a length measuring wheel and a length measuring encoder coaxially connected to the length measuring wheel. The length measuring wheel is located between two adjacent guide wheels.

[0020] Furthermore, the optical fiber winding machine also includes a control system, which includes a processor and a display control panel. The processor is connected to the pay-off motor, take-up motor, wire laying mechanism, tension adjustment mechanism, tension detection mechanism, and length measuring mechanism, respectively.

[0021] Compared with the prior art, the beneficial effects of this utility model are: (1) Each of the clamping top cone assemblies in this application includes a first top cone and a second top cone that are coaxial. After the fiber optic reel and the fiber optic take-up reel are fitted onto the shaft, the two top cones move from both sides of the inner diameter of the fiber optic reel toward the center. By fitting the conical surface of the top cone with the inner diameter of the fiber optic reel, the fiber optic reel is radially clamped and fixed, no longer relying on the strict dimensional matching between the shaft and the inner diameter of the fiber optic reel.

[0022] (2) The top cone position adjustment device of this application is connected to the second top cone and can move along the axial direction of the shaft. For fiber optic discs with different inner diameter specifications, the adjustment device can push the second top cone closer to or further away from the first top cone, change the distance between the two top cones, and thus adapt to fiber optic discs with different inner diameters from large to small.

[0023] (3) The shaft and coupling of this application adopt a detachable connection. Although the shaft structure is retained, the core positioning function has been transferred to the top cone. The shaft only needs to be replaced when facing fiber optic discs of extreme specifications, which greatly reduces the switching frequency of the shaft. The radial clamping of the top cone replaces the inner diameter matching of the traditional shaft, thereby achieving flexible adaptation to fiber optic discs of different specifications and ultimately improving the overall winding efficiency.

[0029] Example 1 like Figure 1 and Figure 3As shown, an optical fiber winding machine includes a frame 1, a fiber optic reel 2 and a fiber optic take-up reel 3 respectively disposed at both ends of the frame 1, a fiber optic motor 4 and a fiber optic take-up motor 5 respectively for driving the fiber optic reel 2 and the fiber optic take-up reel 3, a fiber optic winding mechanism 6 located between the fiber optic reel 2 and the fiber optic take-up reel 3, a plurality of guide wheels 7 arranged sequentially on the fiber optic winding mechanism 6 along the fiber optic forward direction, and a tension adjustment mechanism 9 disposed between two adjacent guide wheels 7, and also includes two sets of clamping top cone assemblies respectively for clamping the fiber optic reel 2 and the fiber optic take-up reel 3. like Figure 2 As shown, each clamping cone assembly includes a coaxially arranged coupling 81, a first cone 82, a shaft 83, a second cone 84, and a cone position adjustment device 85. The coupling 81 is connected to the output end of the pay-off motor 4 / take-up motor 5. One end of the shaft 83 is detachably connected to the coupling 81, and the other end of the shaft 83 is rotatably connected to the frame 1. The first cone 82, the second cone 84, and the cone position adjustment device 85 are coaxially sleeved on the shaft 83 in sequence. The pay-off fiber reel 2 / take-up fiber reel 3 is sleeved on the shaft 83 and located between the first cone 82 and the second cone 84.

[0030] The installation steps of the fiber optic reel 2 or fiber optic take-up reel 3 in this application are as follows: align one side of the fiber optic reel 2 or fiber optic take-up reel 3 with the axis of the first top cone 82, then push the second top cone 84 to the other side of the fiber optic reel 2 or fiber optic take-up reel 3 for alignment and tightening, pass the shaft 83 through the mounting hole of the frame 1 from one side, and fit the top cone position adjustment device 85 on the other side of the frame 1, then pass the shaft 83 sequentially through the second top cone 84, the fiber optic reel 2 or fiber optic take-up reel 3, and the first top cone 82, and finally fix it with the coupling 81, thereby realizing the clamping of fiber optic reels 2 or fiber optic take-up reels 3 of different specifications.

[0031] In this embodiment, the frame 1 is constructed from 4040 aluminum alloy profiles and anodized, combining lightweight and high strength characteristics. The frame's external dimensions are 800mm × 280mm × 250mm (length × width × height). The bottom is equipped with anti-slip rubber pads to ensure stable placement of the equipment on a laboratory bench or mobile cart. Internally, 10mm diameter cable trays are milled for concealed cable routing, improving equipment neatness and electromagnetic compatibility. The top support plate is 8mm thick, with surface-machined positioning grooves with an accuracy of ±0.05mm, ensuring that the concentricity of each functional module is ≤0.1mm, reducing the impact of vibration on winding accuracy.

[0032] In this embodiment, the pay-off motor 4 and the take-up motor 5 are DC servo motors with a rated speed of 3000 rpm and a torque of 0.5 N·m. They drive the fiber optic disc through a 5:1 reduction gearbox, with a speed control accuracy of ±1 rpm. They support forward and reverse switching to meet the requirements of multi-layer fiber winding. The shaft ends of the pay-off motor 4 and the take-up motor 5 are integrated with incremental encoders with a resolution of 1000 lines, which provide real-time feedback on the motor speed and number of rotations to calculate the fiber winding length and realize closed-loop control of the winding process.

[0033] like Figure 4 As shown, the first top cone 82 includes an integrally formed cylindrical section and a frustum section, with the diameter of the frustum section varying from 50mm to 250mm. The structure of the second top cone 84 is the same as that of the first top cone 82. The diameter variation range of the frustum section determines the range of fiber optic disc inner diameters that the clamping top cone assembly can accommodate. A diameter variation range of 50mm to 250mm for the frustum section can accommodate most fiber optic discs, meeting the winding requirements of different fiber optic discs.

[0034] In this embodiment, the surfaces of the first top cone 82 and the second top cone 84 are chrome-plated to reduce rotational friction, ensure that the reel releases the optical fiber smoothly, and avoid sudden changes in optical fiber tension caused by chuck jamming.

[0035] like Figure 4 As shown, the top cone position adjustment device 85 includes a sliding sleeve 851 sleeved on the shaft 83, an elastic element 852 connected to the sliding sleeve 851 and located between the sliding sleeve 851 and the second top cone 84, and a tightening screw 853 with one end passing through the sliding sleeve 851 and abutting against the shaft 83. The tightening screw 853 is threadedly connected to the sliding sleeve 851. The cooperation between the sliding sleeve 851 and the tightening screw 853 can adjust the fixed position of the sliding sleeve 851 on the shaft 83, thereby adjusting the clamping position of the second top cone 84. The elastic element 852 is sleeved on the shaft 83 and located between the sliding sleeve 851 and the second top cone 84. When the top cone clamps the fiber optic disc, the spring will generate elastic deformation, providing a continuous preload force to ensure that the top cone and the inner diameter of the fiber optic disc are tightly fitted, while also counteracting the slight vibration when the fiber optic disc rotates.

[0036] In this embodiment, the elastic element 852 is a spring.

[0037] like Figure 4 As shown, the other end of the tightening screw 853 is equipped with a handle.

[0038] like Figure 4 As shown, the other end of the shaft 83 is rotatably connected to the frame 1 via a bearing. The outer ring of the bearing is fixed on the frame 1, and the inner ring of the bearing is slidably connected to the shaft 83.

[0039] In this embodiment, the guide wheel 7 is a ceramic guide wheel, and the distance between the guide wheel 7 and the tension adjustment mechanism 9 is greater than or equal to 10mm. Using ceramic material effectively prevents scratch damage to the fiber optic coating, such as polyimide coatings and UV-curable adhesive coatings. The minimum distance between the guide wheel 7 and the tension adjustment mechanism 9 ensures a straight fiber optic routing path and reduces bending loss.

[0040] In this embodiment, the guide wheel can be selected with a wheel diameter of 20mm, a groove depth of 0.5mm, and a groove width of 0.2mm. It is made of ceramic material, which can effectively prevent the fiber optic coating, such as the polyimide coating and the UV-cured adhesive coating, from being scratched and damaged during the cable laying process.

[0041] In this embodiment, coupling 81 is a cross-slider coupling. The cross-slider coupling can simultaneously compensate for the radial misalignment of the two shafts, the contact surface is wear-resistant and has good load-bearing capacity, and it is not prone to slippage or breakage under rated load, thus ensuring the continuity of transmission. It is suitable for low-speed winding requirements such as those described in this application.

[0042] like Figure 1 and Figure 3 As shown, the cable laying mechanism 6 includes a cable laying slide 61 and a lead screw mechanism 62 that drives the cable laying slide 61 to move perpendicular to the optical fiber forward direction.

[0043] In this embodiment, the lead screw mechanism 62 includes a ball screw arranged perpendicular to the direction of optical fiber advance, and a stepper motor for driving the ball screw to rotate. The stepper motor drives the ball screw to rotate through a coupling 81.

[0044] In this embodiment, a miniature ball screw with a lead of 1mm and a stepper motor with a step angle of 1.8° and 16 subdivisions are selected. The ball screw is driven to rotate through a coupling, so as to achieve stepless adjustment of the translation speed of the cable laying slide from 0.1 to 5mm / s. The cable laying slide 61 has a stroke of 100mm, a positioning accuracy of ±0.02mm, and a repeatability of ±0.01mm. It can meet the cable laying requirements of different take-up lengths within the range of 10-100mm. The cable laying slide 61 integrates photoelectric limit switches at both ends to prevent the slide from overtravel and collision, and ensure the safe operation of the equipment.

[0045] like Figure 1 As shown, the tension adjustment mechanism 9 includes a dance wheel 91 and a piezoelectric ceramic actuator 92 that is connected to and drives the dance wheel 91 to move up and down.

[0046] In this embodiment, the piezoelectric ceramic actuator 92 has a stroke of ±5mm, a response time of ≤10ms, and an adjustment sensitivity of 0.001N / μm. The dancing wheel 91 has a diameter of 20mm and a surface smoothness Ra≤0.05μm. When the optical fiber is wound around the dancing wheel 91, the control system drives the piezoelectric ceramic actuator 92 to adjust the position of the dancing wheel 91 in real time based on the deviation value fed back by the tension sensor. When the tension is too high, the dancing wheel 91 moves down to release the optical fiber; when the tension is too low, the dancing wheel 91 moves up to tighten the optical fiber, thereby achieving dynamic tension balance and a control accuracy of ±0.01N.

[0047] The advantages of this application are as follows: Each clamping cone assembly includes a coaxial first cone 82 and a second cone 84. After the fiber optic reel 2 and the fiber optic reel 3 are mounted on the shaft 83, the two cones move from both sides of the inner diameter of the fiber optic reel towards the center. By fitting the conical surface of the cone with the inner diameter of the fiber optic reel, the fiber optic reel is radially clamped and fixed, no longer relying on a strict dimensional match between the shaft 83 and the inner diameter of the fiber optic reel. The cone position adjustment device 85 is connected to the second cone 84 and can move axially along the shaft 83. For fiber optic reels with different inner diameter specifications, the adjustment device can push... The second apex cone 84 moves closer to or further away from the first apex cone 82, changing the distance between the two apex cones to accommodate fiber optic discs with different inner diameters from large to small. The shaft 83 and the coupling 81 are detachably connected. Although the shaft 83 structure is retained, the core positioning function has been transferred to the apex cone. The shaft 83 only needs to be replaced when dealing with fiber optic discs of extreme specifications, which greatly reduces the switching frequency of the shaft 83. This application uses the radial clamping of the apex cone to replace the inner diameter matching of the traditional shaft 83, thereby achieving flexible adaptation to fiber optic discs of different specifications and ultimately improving the overall winding efficiency.

[0048] Example 2 This embodiment is similar to Embodiment 1, except that in this embodiment: like Figure 1 and Figure 3 As shown, the fiber winding machine also includes a tension detection mechanism, which includes a tension wheel 100 and a tension sensor connected to the tension wheel 100. The tension wheel 100 is located between two adjacent guide wheels 7.

[0049] In this embodiment, a miniature tension sensor with a range of 0-1N, an accuracy of ±0.005N, and a sampling frequency of 1kHz is used. It is connected in series with the optical fiber winding path to collect optical fiber tension data in real time. The output signal of the tension sensor is transmitted to the control system after analog-to-digital conversion, providing a basis for dynamic tension adjustment.

[0050] In this embodiment, the distance between the guide wheel 7 and the tension wheel 100 is greater than or equal to 10 mm. This minimum distance between the guide wheel 7 and the tension wheel 100 ensures a straight fiber optic cable path and reduces bending loss.

[0051] like Figure 1 and Figure 3 As shown, the fiber winding machine also includes a length measuring mechanism, which includes a length measuring wheel 200 and a length measuring encoder coaxially connected to the length measuring wheel 200. The length measuring wheel 200 is located between two adjacent guide wheels 7.

[0052] In this embodiment, the measuring wheel 200 has a diameter of 20mm, an accuracy of ±0.01mm, and a surface covered with a hard rubber layer. The fiber optic cable wraps around the measuring wheel at a 90° angle to ensure reliable contact without slippage, with a slippage rate ≤0.05%. The length encoder is coaxially connected to the measuring wheel 200, has a resolution of 2000 lines, and outputs 2000 pulses per rotation.

[0053] In this embodiment, the optical fiber passes through the fiber optic cable reel 2 in sequence, then through the guide wheel 7, the tension wheel 100, and the guide wheel 7 to form a triangular envelope path. The envelope angle at the tension wheel 100 is 60°, ensuring that there are no blind spots in tension detection and achieving precise tension control throughout the entire path.

[0054] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0055] Example 3 This embodiment is similar to Embodiment 1, except that in this embodiment: like Figure 1 and Figure 3 As shown, the fiber optic winding machine also includes a control system 300, which includes a processor and a display control panel. The processor is connected to the wire feeding motor 4, the wire taking-up motor 5, the wire laying mechanism 6, the tension adjustment mechanism 9, the tension detection mechanism, and the length measuring mechanism.

[0056] In this embodiment, the tension sensor and length encoder input signals to the processor, and the processor outputs control commands to the pay-off motor 4, the take-up motor 5, the piezoelectric ceramic driver 92 and the lead screw mechanism 62 to achieve intelligent winding.

[0057] In this embodiment, the display control panel includes a touch screen interactive configuration. A touch screen display is selected to display parameters such as fiber tension, take-up motor speed, winding length, and number of turns in real time. It supports manual input of target winding parameters, such as target tension of 0.3N and target wire spacing of 0.2mm. It supports one-key start / pause / reset operations to realize convenient local control of the fiber optic winding machine.

[0058] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
