Description

Technical Field

[0001] This utility model relates to an optical fiber protection device, specifically an auxiliary device for winding optical fiber rings. Background Technology

[0002] The optical fiber extending from the supply module is wound onto the frame. During the winding process, the optical fibers need to be neatly arranged. During winding, the behavior of the fiber is affected by factors such as friction between the fiber and the frame, pressure distribution within the fiber, and the fiber's material properties and elastic modulus. Fluctuations in fiber tension can lead to uneven stress, causing localized bending or bulging. As the number of fiber layers increases, each layer is constrained by the previous layer, making it difficult for new fibers to fully conform to the previous ones, resulting in bulges and an uneven surface on the final wound fiber. Utility Model Content

[0003] The purpose of this invention is to provide a wire protection auxiliary device for winding optical fiber rings, and the technical problem to be solved is how to improve the flatness of the optical fiber surface during the optical fiber winding process.

[0004] This utility model is achieved through the following technical solution:

[0005] A wire protection auxiliary device for winding optical fiber rings is disposed directly above a frame; the wire protection auxiliary device includes a rake moving assembly and a rake assembly, the rake assembly being disposed on the rake moving assembly, the rake moving assembly being positioned at a corresponding position on the frame and driving the rake assembly to move.

[0006] The aforementioned rake assembly includes a rake head and a rake connecting part. The two ends of the rake connecting part are respectively connected to the rake head and the rake moving assembly. The rake head is used to extend towards the skeleton. The end of the rake head that extends to the skeleton is provided with a groove, which is used to abut against the winding layer optical fiber.

[0007] The aforementioned rake head has a groove at one end extending to the frame. This groove abuts against the optical fiber of the winding layer, ensuring that each loop of fiber is tightly arranged along a predetermined path. This avoids fiber misalignment or overlap caused by low fiber alignment accuracy, which not only helps maintain the parallelism between fiber layers but also prevents stress concentration caused by uneven fiber alignment, thereby reducing the risk of fiber damage due to excessive local stress. Combining the rake assembly and the rake moving assembly allows the rake head to move in a specific direction as needed to accommodate fiber loops of different diameters. Its position can be dynamically adjusted during winding, ensuring that each loop of fiber is placed in its corresponding position, improving fiber alignment accuracy, reducing the need for manual intervention, and thus enhancing the automation level of the entire winding process. By controlling the position of the rake head and its contact method with the fiber (i.e., through the groove), the fiber is guided and supported without affecting the fiber tension, effectively improving the flatness of the fiber surface.

[0008] Furthermore, the aforementioned rake moving assembly includes a lateral moving component and a longitudinal moving component, wherein the longitudinal moving component is disposed on the lateral moving component, and the lateral moving component is used to drive the longitudinal moving component to move along the axial direction of the frame.

[0009] The rake assembly is mounted on the longitudinal moving part, which drives the rake assembly to move radially along the frame.

[0010] The lateral moving component drives the longitudinal moving component to translate along the skeleton axis (i.e., along the length of the fiber ring). The fiber in the winding layer is spirally wound, with the number of turns gradually increasing and the fiber ring length increasing. The lateral moving component drives the rake assembly to translate, ensuring that each turn of fiber is accurately placed in the correct position, avoiding misalignment or overlap between fiber layers due to fiber alignment angle deviations. The longitudinal moving component drives the rake assembly to translate radially along the skeleton (i.e., perpendicular to the length of the fiber ring), allowing the rake head to adjust its distance from the current winding layer each time a new fiber layer is added. This ensures that the newly wound fiber is tightly attached to the previous fiber layer (i.e., the inner fiber), thereby improving the flatness of the fiber surface. This bidirectional movement mechanism not only improves winding accuracy but also enhances control over fiber alignment quality. In the case of multi-layer winding, the independent and coordinated movements in both the lateral and longitudinal dimensions ensure that the fibers are tightly arranged along a predetermined trajectory, forming a flat, uniform, and stable structure.

[0011] Furthermore, the aforementioned lateral moving component includes a support frame and a first driver, wherein the support frame is provided with a first slide rail for being arranged parallel to the axial direction of the skeleton.

[0012] The first slide rail is provided with a first slider, and a first driver is connected to the first slider. The first driver is used to drive the first slider to slide along the first slide rail.

[0013] The aforementioned support frame, serving as the foundation structure of the entire lateral movement assembly, not only supports the relevant mechanical components but also ensures high stability during operation. The first slide rail on the support frame is arranged parallel to the skeleton axis. This first slide rail guides the first slider to translate along the length of the fiber loop, ensuring the rake assembly moves in the same direction as the fiber winding, thus guaranteeing that each loop of fiber is placed in the correct position. The first slide rail cooperates with the first slider; when the first driver is activated, it pushes the first slider to move along the first slide rail. Because the first slide rail is parallel to the skeleton axis, each movement of the first slider is linear and smooth, avoiding any lateral displacement that could affect the fiber alignment quality.

[0014] Furthermore, the aforementioned longitudinal moving member includes a second slider and a second driver, wherein the second slider is connected to the second driver;

[0015] The aforementioned first slider is provided with a first connecting block, and the first connecting block extends out of a first slide rail;

[0016] The first connecting block is provided with a second slide rail on its side, and the second slide rail is arranged perpendicular to the length direction of the first slide rail.

[0017] The second slider is mounted on the second slide rail, and the second driver is used to drive the second slider to slide along the second slide rail.

[0018] The second slider is connected to the second driver, which transmits power to the second slider, causing the second slider to translate on the second slide. The rake assembly moves radially along the skeleton (i.e., perpendicular to the length of the fiber ring), thereby adjusting the spacing between the rake head and the current winding layer. The first connecting block extends from the first slide and is provided with a longitudinal moving part, breaking the limitation of a single dimension and allowing a new degree of freedom (i.e., longitudinal movement) to be added on the basis of lateral movement.

[0019] Furthermore, the line protection auxiliary device also includes a CCD detection device and a processor. The CCD detection device is mounted on the rake moving assembly, which is used to move the CCD detection device.

[0020] The processor is connected to a CCD detection device, a first driver, and a second driver. The CCD detection device is used to detect the fiber winding position and the position of the rake head. The processor is used to call the rake head movement strategy, generate control commands, and send the control commands to the first driver and the second driver based on the received fiber winding position and rake head position.

[0021] The aforementioned CCD (Charge-Coupled Device) moves along with the rake assembly, monitoring the fiber winding position and the rake head position in real time. This ensures the CCD detection equipment is always at the optimal observation angle, capturing the clearest and most accurate image information, providing a reliable foundation for subsequent data processing. The processor receives information about the fiber winding position and rake head position from the CCD detection equipment and makes decisions based on this, establishing the existing rake head movement strategy. According to the preset rake head movement strategy, corresponding control commands are generated, guiding the actions of the first and second drivers. This achieves closed-loop management from detection to feedback and then to control, improving the stability and accuracy of the winding process.

[0022] Furthermore, the rake head is provided with a protrusion at one end that extends to the frame, and the protrusion is located on the side of the groove.

[0023] The side of the aforementioned protrusion near the groove is used to contact the winding layer optical fiber.

[0024] The aforementioned protrusions are positioned beside the groove, meaning they are near the contact area between the rake head and the optical fiber in the winding layer, but do not directly occupy the space of the groove. This ensures that the protrusions do not obstruct the optical fiber from entering or leaving the winding position through the groove, while also providing auxiliary positioning during the winding process. The side of the protrusion closest to the groove is used to contact the optical fiber in the winding layer, allowing the protrusion to protect the optical fiber being wound, help guide its correct direction, and prevent the optical fiber from deviating from the predetermined path. Since the protrusions only contact the optical fiber without applying excessive pressure, damage to the optical fiber, such as surface scratches or internal breaks, can be avoided.

[0025] Furthermore, the raised surface of the aforementioned bump is used to extend toward the inner fiber, and a gap is left between the raised surface and the inner fiber.

[0026] The raised surface of the aforementioned bump does not contact the already wound bottom fiber (i.e., inner fiber) to avoid squeezing the bottom fiber and causing unevenness on the bottom fiber surface.

[0027] Furthermore, the edges of the aforementioned grooves and protrusions are all provided with curved surfaces.

[0028] Designing the edges of the aforementioned grooves and protrusions as curved surfaces reduces the contact stress between the optical fiber and the edges, avoiding localized stress concentration caused by sharp edges. The curved surfaces also guide the optical fiber more smoothly through these areas, reducing friction and thus lowering the risk of scratches on the fiber surface. Especially during fiber winding, any minor damage can lead to a decrease in signal transmission performance; therefore, the curved surface design can, to a certain extent, ensure the quality of the fiber optic ring.

[0029] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0030] The aforementioned rake head has a groove at one end extending to the frame. This groove abuts against the optical fiber of the winding layer, ensuring that each loop of fiber is tightly arranged along a predetermined path. This avoids fiber misalignment or overlap caused by low fiber alignment accuracy, which not only helps maintain the parallelism between fiber layers but also prevents stress concentration caused by uneven fiber alignment, thereby reducing the risk of fiber damage due to excessive local stress. Combining the rake assembly and the rake moving assembly allows the rake head to move in a specific direction as needed to accommodate fiber loops of different diameters. Its position can be dynamically adjusted during winding, ensuring that each loop of fiber is placed in its corresponding position, improving fiber alignment accuracy, reducing the need for manual intervention, and thus enhancing the automation level of the entire winding process. By controlling the position of the rake head and its contact method with the fiber (i.e., through the groove), the fiber is guided and supported without affecting the fiber tension, effectively improving the flatness of the fiber surface.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0039] First embodiment:

[0040] Combination Figure 1 and Figure 2 A wire protection auxiliary device for winding optical fiber rings is provided, which is located directly above the frame 1. The wire protection auxiliary device includes a rake moving assembly and a rake assembly 4. The rake assembly 4 is disposed on the rake moving assembly, which is used to be positioned at a corresponding position on the frame 1 and to drive the rake assembly 4 to move.

[0041] The aforementioned rake assembly 4 includes a rake head 42 and a rake connecting portion 41. The two ends of the rake connecting portion 41 are respectively connected to the rake head 42 and a rake moving assembly. The rake head 42 extends towards the frame 1. A groove 43 is provided at one end of the rake head 42 extending to the frame 1. This groove 43 abuts against the wound layer optical fiber, combining... Figure 3 and Figure 4 .

[0042] The aforementioned rake head 42 extends to one end of the frame 1 and has a groove 43. This groove 43 abuts against the optical fiber of the winding layer, ensuring that each loop of optical fiber is tightly arranged according to a predetermined path. This avoids optical fiber misalignment or overlap caused by low fiber alignment accuracy. The groove 43 presses down on the optical fiber of the winding layer, keeping the optical fibers of the winding layer on the same horizontal plane, maintaining the parallelism between optical fiber layers, and preventing stress concentration caused by uneven fiber alignment, thereby reducing the risk of optical fiber damage caused by excessive local stress. Combined with the rake assembly 4 and the rake moving assembly, the rake head 42 is allowed to move in a specific direction as needed to adapt to optical fiber rings of different diameters. During the winding process, the position can be dynamically adjusted so that each loop of optical fiber can be placed in the corresponding position, improving fiber alignment accuracy, reducing the need for manual intervention, and thus improving the automation level of the entire winding process. By controlling the position of the rake head 42 and its contact with the optical fiber (i.e., through the groove 43), the optical fiber is guided and supported without affecting the fiber tension, effectively improving the flatness of the optical fiber surface.

[0043] Second embodiment:

[0044] Based on the first embodiment, the above-mentioned rake moving assembly includes a transverse moving part 2 and a longitudinal moving part 3. The longitudinal moving part 3 is disposed on the transverse moving part 2, and the transverse moving part 2 is used to drive the longitudinal moving part 3 to move along the axial direction of the frame 1.

[0045] The rake assembly 4 is mounted on the longitudinal moving part 3, which is used to drive the rake assembly 4 to move radially along the frame 1.

[0046] The aforementioned lateral moving component 2 drives the longitudinal moving component 3 to translate along the axial direction of the skeleton 1 (i.e., along the length of the fiber ring). The fiber in the winding layer is spirally wound, and during the winding process, the number of fiber turns gradually increases, and the length of the fiber ring lengthens. The lateral moving component 2 drives the rake assembly 4 to translate, ensuring that each fiber turn is accurately placed in the correct position, avoiding misalignment or overlap between fiber layers due to fiber arrangement angle deviations. The longitudinal moving component 3 drives the rake assembly 4 to translate radially along the skeleton 1 (i.e., perpendicular to the length of the fiber ring), allowing the rake head 42 to adjust its distance from the current winding layer each time a new fiber layer is added. This ensures that the newly wound fiber is tightly attached to the previous fiber layer (i.e., the inner fiber), thereby improving the flatness of the fiber surface. This bidirectional movement mechanism not only improves winding accuracy but also enhances control over the fiber alignment quality. In the case of multi-layer winding, the independent and coordinated movements in both the lateral and longitudinal dimensions ensure that the fibers are tightly arranged along a predetermined trajectory, forming a flat, uniform, and stable structure.

[0047] The groove 43 on the rake head 42 abuts against the optical fiber of the winding layer. In conjunction with the lateral and longitudinal moving parts 3, the optical fiber is guided to be closely arranged along a predetermined path. The groove 43 presses down on the optical fiber during winding, so that the optical fiber of the winding layer is on the same horizontal plane, which improves the flatness of the optical fiber surface of the winding layer.

[0048] In a specific embodiment, the aforementioned transverse moving member 2 includes a support frame 23 and a first driver 25. The first driver 25 is disposed on the support frame 23, and the support frame 23 is provided with a first slide rail 24, which is arranged parallel to the axial direction of the frame 1.

[0049] A first slider 22 is provided on the first slide rail 24, and a first driver 25 is connected to the first slider 22. The first driver 25 is used to drive the first slider 22 to slide along the first slide rail 24.

[0050] The first driver 25 can be configured with a stepper motor, a lead screw, and a limiting rod. The limiting rod and the lead screw are arranged parallel to each other in the first slide rail 24. The shaft of the stepper motor is connected to the lead screw (which can be welded). The first slider 22 is provided with a limiting hole and a threaded hole. The lead screw passes through the threaded hole and is threaded. The limiting rod passes through the limiting hole and slides within the limiting hole. After the stepper motor is started, the lead screw rotates, driving the first slider 22 to move.

[0051] The aforementioned first actuator 25 can also be a hydraulic cylinder, which is mounted on a support frame. The output shaft of the hydraulic cylinder is connected to the first connecting block 21, pushing the first connecting block 21 to move laterally, such as... Figure 2 As shown.

[0052] The aforementioned support frame 23 serves as the foundation structure of the entire lateral movement assembly, not only supporting the relevant mechanical components but also ensuring high stability during operation. The first slide rail 24 on the support frame 23 is arranged parallel to the axial direction of the frame 1. The first slide rail 24 guides the first slider 22 to translate along the length of the fiber loop, ensuring that the rake assembly 4 moves in the same direction as the fiber winding, thus ensuring that each loop of fiber is placed in the correct position. The first slide rail 24 cooperates with the first slider 22; when the first driver 25 is activated, it pushes the first slider 22 to move along the first slide rail 24. Because the first slide rail 24 is parallel to the axial direction of the frame 1, each movement of the first slider 22 is linear and smooth, avoiding any lateral displacement that might affect the fiber alignment quality.

[0053] In a specific embodiment, the longitudinal moving member 3 includes a second slider 31 and a second driver 34, wherein the second slider 31 is connected to the second driver 34;

[0054] The first slider 22 is provided with a first connecting block 21, and the first connecting block 21 extends out of the slide rail;

[0055] The side of the first connecting block 21 is provided with a second slide rail 33, which is arranged perpendicular to the length direction of the first slide rail 24.

[0056] The second slider 31 is disposed on the second slide rail 33, and the second driver 34 is disposed on the first connecting block 21. The second driver 34 is used to drive the second slider 31 to slide along the second slide rail 33.

[0057] The second driver 34 can be configured with a stepper motor, a lead screw, and a limiting rod. The limiting rod and the lead screw are arranged parallel to each other in the second slide rail 33. The shaft of the stepper motor is connected to the lead screw (which can be welded). The first slider 22 is provided with a limiting hole and a threaded hole. The lead screw passes through the threaded hole and is adapted to the thread. The limiting rod passes through the limiting hole and slides within the limiting hole. After the stepper motor is started, the lead screw rotates, driving the second slider 31 to move.

[0058] The second actuator 34 described above can also be a hydraulic cylinder. The hydraulic cylinder is mounted on the first connecting block 21, and its output shaft is connected to the second slider 31 via a crossbar. The second slider 31 is connected to the second connecting block 32, which pushes the second connecting block 32 to move longitudinally. Figure 1 As shown.

[0059] The second slider 31 is provided with a second connecting block 32, and the second connecting block 32 extends into a second slide rail 33; the rake assembly 4 is provided on the second connecting block 32;

[0060] The second slider 31 is connected to the second driver 34. The second driver 34 transmits power to the second slider 31, causing the second slider 31 to translate on the second slide rail 33. The rake assembly 4 moves radially along the skeleton 1 (i.e., perpendicular to the length of the fiber ring), thereby adjusting the spacing between the rake head 42 and the current winding layer. The first connecting block 21 extends from the first slide rail 24. A longitudinal moving part 3 is provided on the first connecting block 21, breaking the limitation of a single dimension and allowing a new degree of freedom (i.e., longitudinal movement) to be added on the basis of lateral movement.

[0061] Third embodiment:

[0062] Based on any of the above embodiments, combined with Figure 1 The line protection auxiliary device also includes a CCD detection device 5 (which may be a Sony ICX625DL, DALSA Piranha HS series line array CCD camera, Kodak KAF-16803 image sensor, etc.) and a processor (which may be a microcontroller, PLC, etc.). The CCD detection device 5 is mounted on the second connecting block 32, and the rake moving component is used to drive the CCD detection device 5 to move.

[0063] The processor is connected to the CCD detection device 5, the first driver 25, and the second driver 34. The CCD detection device 5 is used to detect the fiber winding position and the position of the rake head 42. The processor is used to call the rake head 42 movement strategy according to the received fiber winding position and rake head 42 position, generate control commands, and send the control commands to the first driver 25 and the second driver 34.

[0064] The aforementioned CCD (charge-coupled device) moves along with the rake assembly 4, monitoring the fiber winding position and the position of the rake head 42 in real time. This ensures that the CCD detection device 5 is always at the optimal observation angle, capturing the clearest and most accurate image information, providing a reliable foundation for subsequent data processing. The processor, acting as the "brain" of the entire system, is connected not only to the CCD detection device 5 but also to the first driver 25 and the second driver 34. The processor receives information about the fiber winding position and the rake head 42 position from the CCD detection device 5 and makes decisions based on this information, establishing the existing rake head 42 movement strategy. Based on the preset rake head 42 movement strategy, the processor generates corresponding control commands, which in turn guide the actions of the first driver 25 and the second driver 34. This achieves closed-loop management from detection to feedback to control, improving the stability and accuracy of the winding process.

[0065] Fourth embodiment:

[0066] Based on any of the above embodiments, the rake head 42 is further provided with a protrusion 44 at one end extending to the frame 1, and the protrusion 44 is provided on the side of the groove 43.

[0067] The side of the protrusion 44 near the groove 43 is smoothly connected to the inner side of the groove 43;

[0068] The aforementioned protrusion 44, near the groove 43, is used to contact the wound layer optical fiber, combined with Figure 4 .

[0069] The aforementioned protrusion 44 is located beside the groove 43, meaning that the protrusion 44 is near the contact area between the rake head 42 and the optical fiber of the winding layer, but does not directly occupy the space of the groove 43. This ensures that the protrusion 44 will not hinder the optical fiber from entering or leaving the winding position through the groove 43, and at the same time, it can play an auxiliary positioning role during the winding process. The side of the protrusion 44 near the groove 43 is used to contact the optical fiber of the winding layer, so that the protrusion 44 can protect the optical fiber being wound, help guide its correct direction, and prevent the optical fiber from deviating from the predetermined path. Since the protrusion 44 only contacts the optical fiber without applying excessive pressure, it can avoid damage to the optical fiber, such as surface scratches or internal breakage.

[0070] In a specific embodiment, the raised surface of the aforementioned bump 44 is used to extend towards the inner fiber, and a gap is left between the raised surface and the inner fiber, combined with... Figure 4 .

[0071] The raised surface of the aforementioned bump 44 does not contact the already wound bottom fiber (i.e. inner fiber), thus avoiding compression of the bottom fiber and causing unevenness on the bottom fiber surface.

[0072] In a specific embodiment, the edges of the groove 43 and the protrusion 44 are both provided with arc surfaces.

[0073] Designing the edges of the grooves 43 and protrusions 44 as curved surfaces reduces the contact stress between the optical fiber and the edges, avoiding localized stress concentration caused by sharp edges. The curved surfaces also guide the optical fiber more smoothly through these areas, reducing friction and thus lowering the risk of scratches on the fiber surface. Especially during fiber winding, any minor damage can lead to a decrease in signal transmission performance; therefore, the curved surface design can, to a certain extent, ensure the quality of the fiber optic ring.

[0074] Work process:

[0075] (1) Before the winding begins, the optical fiber winding position and the position of the rake head 42 are monitored by the CCD detection device 5. According to the control command issued by the processor, the rake head 42 is moved to the designated position by the first driver 25 and the second driver 34. At this time, the protruding surface of the bump 44 has a height difference with the inner optical fiber, and the groove 43 is located at the optical fiber winding position.

[0076] (2) When the optical fiber to be wound enters the winding position along the groove 43, the groove 43 presses down on the optical fiber to be wound, and the protrusion 44 protects the optical fiber to be wound on the side close to the groove 43, playing a guiding and supporting role.

[0077] (3) When winding one layer, turn off the second driver 34 so that the distance between the rake head 42 and the inner fiber remains unchanged; adjust the horizontal position of the rake head 42 by the first driver 25, and keep the groove 43 and the protrusion 44 in contact with the fiber to be wound to ensure that each turn of fiber can be wound accurately according to the preset trajectory.

[0078] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
