Abstract
Description
Technical Field
[0001] This invention relates to the field of optical fiber ring fabrication technology, and in particular to a high-precision optical fiber winding system and method. Background Technology
[0002] With the continuous development of fiber optic technology, fiber optic gyroscopes have greater advantages than traditional mechanical and laser gyroscopes, and their application prospects are becoming increasingly broad. The most important factor limiting the accuracy of fiber optic gyroscopes is the fiber optic loop, which is a loop of fiber optic cable wound according to specific process requirements. A fiber optic winding machine is a specialized device for winding fiber optic cables. The diameter of the fiber used to wind the loop is smaller than that of ordinary fiber optic cables, and the tension maintained during the winding process is also smaller. Furthermore, fiber optics tend to straighten, and adjacent turns of fiber repel each other due to electrostatic discharge. These requirements present significant technical challenges to the orderly arrangement of the fiber optic loop. Current technologies require manual intervention in real-time to achieve orderly fiber alignment. This process inevitably applies external stress to the fiber, affecting the performance indicators of the fiber optic loop. Taking existing fiber optic winding machine structures, such as the fiber optic winding auxiliary fiber arrangement device described in patent documents CN110926452A and CN211234448U_fully automatic fiber optic gyroscope winding machine, as examples, as an example, in order to overcome the straightness and electrostatic repulsion of the fiber, the existing technology uses a pressure bar to press down on the wound fiber. The problem is that the pressure bar can easily damage the surface of the fiber, and the micro-jumping of the pressure bar end on the fiber surface also leads to uneven winding tension of the fiber. Since the diameter of the fiber is in the micrometer range, for example, 50~100 micrometers, which is roughly the thickness of a human hair, existing fiber optic guide wheels or rods, such as the structure described in CN203545326U_fiber optic guide wheel mechanism for automatic fiber optic winding machine, also have the problem of difficulty in accurately controlling the position of the fiber during the reversal process. That is, during the reversal, the fiber will always have relative displacement between itself and the fiber optic guide wheel or rod, which makes it technically difficult to accurately control the fiber entry angle, especially the fiber entry angle at the reversal position. At the fiber optic upsizing stage, a wedge-shaped angle is formed between the fiber and the inner wall of the fiber optic ring frame. This wedge-shaped angle compresses the fiber to complete the upsizing, i.e., from the current turn to the next turn. The problem is that the wedge-shaped angle causes the fiber to bend unevenly at this position. Since fiber optic transmission is based on the principle of total internal reflection, these uneven bends will affect the accuracy of fiber optic transmission, and thus affect the accuracy of the fiber optic ring. Summary of the Invention
[0003] The technical problem to be solved by this invention is to provide a high-precision optical fiber winding system that overcomes the difficulties in optical fiber winding caused by the straightness and repulsive electrostatics of the optical fiber during the winding process in the prior art. In a preferred embodiment, it also solves the problem of uneven bending of the optical fiber during layering.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a high-precision optical fiber winding system, including a winding drive device, the winding drive device is disposed on one side of the glue tank, the winding drive device is used to drive the optical fiber ring to rotate, and the optical fiber ring is at least partially immersed in the glue in the glue tank.
[0005] It is also equipped with a transverse movement mechanism, on which there is an optical fiber guide wheel. The optical fiber guide wheel is used to guide the optical fiber to move back and forth. The direction of movement of the optical fiber guide wheel is parallel to the axis of the optical fiber ring.
[0006] It is also equipped with a camera, which is used to capture images of the optical fiber and the optical fiber loop;
[0007] It also features a focused curing laser device, which is used to cure the adhesive between the optical fiber and the optical fiber ring.
[0008] In a preferred embodiment, the fiber guide wheel guides the fiber from the bottom of the fiber ring into the winding, and the bottom of the fiber ring is immersed in the adhesive.
[0009] In the preferred embodiment, no pressure bar is provided on the surface of the fiber optic ring;
[0010] The second camera is positioned near the optical fiber, and its field of view covers the portion of the optical fiber and the location where the optical fiber contacts the optical fiber ring.
[0011] An enveloping diffuse reflection light source is provided around the optical fiber.
[0012] In a preferred embodiment, the focused curing laser device is located at the bottom of the glue tank, both of which are made of transparent material. The focal point of the focused curing laser device is located on the surface of the fiber optic ring and tracks the position of the fiber winding.
[0013] Alternatively, the focused curing laser device can be located on one side of the glue tank, with the focal point of the focused curing laser device located on the surface of the fiber optic ring and tracking the position of the fiber winding.
[0014] In the preferred embodiment, the structure of the focused curing laser device is as follows: a reflector and a convex lens are sequentially arranged in the optical path of the array laser so that the multiple beams of light from the array laser are converged to a single point.
[0015] In the preferred embodiment, the focused curing laser device is mounted on the mechanical gripper of the multi-axis robotic arm, and the focus is tracked by the movement of the mechanical gripper.
[0016] In a preferred embodiment, the optical fiber guide wheel has a structure in which multiple first baffles and second baffles are arranged radially and alternately, and inclined surfaces are provided on the opposite sides of the first baffles and second baffles, with the inclined surfaces of the first baffles and second baffles forming a V-shaped groove.
[0017] A control method using the above-mentioned high-precision fiber optic winding system includes the following steps:
[0018] S1. Place the fiber optic ring in the glue tank, with the bottom of the fiber optic ring immersed in the glue in the glue tank.
[0019] S2. The optical fiber is wound from the bottom of the optical fiber ring onto the optical fiber ring. The second camera is located on one side of the glue tank and takes images of the optical fiber and the optical fiber ring. The position of the optical fiber guide wheel is controlled according to the images and the fiber entry angle so that the optical fiber is wound on the surface of the optical fiber ring along the fiber entry angle.
[0020] S3. The focal point of the focused curing laser device is concentrated within a certain distance after the optical fiber and the optical fiber ring come into contact.
[0021] Through the above steps, high-precision fiber optic winding is achieved.
[0022] In the preferred embodiment, in step S3, the focused curing laser device is set on the mechanical gripper of the multi-axis robotic arm. The beam of the array laser will only cure the glue after it converges, and the beam will not cure the glue while passing through the glue.
[0023] The first or second camera acquires images of the fiber optic ring, identifies the position of the current turn based on the fiber optic ring images, calculates the elevation of the current turn, and calculates the focal point position that needs to be fixed between the fiber and the fiber optic ring.
[0024] The focal point of the focused curing laser device is aligned with the calculated focal point position that needs to be cured.
[0025] In a preferred embodiment, step S4 is further included, in which a layering wedge is set at each layering position of the fiber ring to prevent the fiber from being squeezed and deformed at each layering position.
[0026] The specific steps are as follows: S401, the first camera or the second camera acquires images of the fiber optic loop;
[0027] S402. Identify the current position of the fiber optic loop;
[0028] S403. Calculate the current turn elevation and the rise angle position. The rise angle position refers to the position of the current turn fiber in terms of angle and axis when it rises to the next layer.
[0029] S404: The focal point of the focused curing laser device is aligned with the rise-up angle position, and the curing process generates a rise-up wedge, so that the optical fiber can rise to the next layer without deformation.
[0030] This invention provides a high-precision optical fiber winding system and method, which has the following advantages compared with the prior art:
[0031] 1) The present invention adopts a method of making loops in the glue, which can overcome the problem of the straightness of the optical fiber by utilizing the viscosity of the glue, and overcome the problem of electrostatic repulsion between optical fibers by utilizing the glue.
[0032] 2) When used with a focused curing laser device, a low-power beam can be focused into a focal light source that is sufficient to cure the adhesive. This allows the optical fiber to be fixed online during the winding process, preventing it from scattering. This results in a uniform, high-quality optical fiber ring and improves the accuracy of the final fiber optic gyroscope product.
[0033] 3) The radially staggered arrangement of the first and second baffles can form a high-precision V-groove, thereby accurately controlling the fiber insertion angle and ensuring that the fiber is neatly arranged and has uniform tension.
[0034] 4) The image recognition control method for fiber entry angle can eliminate the need for pressure bar structure and further improve the uniformity of fiber winding.
[0035] 5) The scheme of pre-setting the upgrade wedge can avoid the fiber from being deformed due to compression during the upgrade process, and further improve the accuracy of the fiber ring. Attached Figure Description

[0046] Example 1:
[0047] like Figures 1-2 A high-precision optical fiber winding system includes a winding drive device 8, which is equipped with a motor, preferably a servo motor, for driving the optical fiber ring frame 81 to rotate at a preset speed. The winding drive device 8 is located on one side of an adhesive tank 2, and the optical fiber ring 1 is at least partially immersed in the adhesive in the adhesive tank 2. This structure can reduce the influence of the optical fiber 12's straightening property because the adhesive has a certain viscosity, which buffers the tension changes of the optical fiber, and the corresponding straightening rebound of the optical fiber is also buffered accordingly, thereby significantly reducing the influence of the optical fiber 12's straightening property on the winding operation. Furthermore, the adhesive has a certain conductivity, thereby neutralizing the effect of static electricity generated by the optical fiber 12.
[0048] A transverse movement mechanism 10 is also provided. In this example, the transverse movement mechanism 10 adopts a screw drive mechanism, such as a screw and nut mechanism to drive precise reciprocating movement. The transverse movement mechanism 10 is provided with an optical fiber guide wheel 4, which is used to guide the optical fiber 12 to reciprocate. The movement direction of the optical fiber guide wheel 4 is parallel to the axis of the optical fiber ring 1.
[0049] Preferred solutions include Figure 1 In the middle, the glue tank 2 is set on the lifting bracket 9. This structure can accommodate optical fiber rings 1 of different diameters.
[0050] A camera is also provided, which is used to capture images of fiber optic cable 12 and fiber optic ring 1;
[0051] like Figure 1 , 3 In section 4, a focused curing laser device 3 is also provided, which is used to cure the adhesive between the optical fiber 12 and the optical fiber ring 1. Figure 3 As shown, fiber slippage is prevented by curing the adhesive between the optical fibers. Preferably, the curing is performed using intermittent points.
[0052] Preferred solutions include Figure 1In this configuration, the fiber guide wheel 4 guides the fiber optic cable 12 into the winding from the bottom of the fiber optic ring 1, with the bottom of the fiber optic ring 1 immersed in the adhesive. This structure ensures that the fiber optic cable 12 entering from the bottom will preferentially contact the adhesive, making the fiber optic cable more compliant and easier to wind.
[0053] Preferred solutions include Figure 1 In this design, no pressure bar is placed on the surface of the fiber ring 1; this structure avoids the damage to the outer wall of the fiber caused by the pressure bar structure and the uneven tension caused by the pressure bar's jump.
[0054] like Figure 1 In the middle, the second camera 7 is set near the optical fiber 12, and the field of view of the second camera 7 covers the part of the optical fiber 12 and the position where the optical fiber 12 contacts the optical fiber ring 1; with this structure, it is easy to identify the position of the optical fiber 12 through image recognition, thereby controlling the precise fiber entry angle α.
[0055] An encircling diffuse reflection light source 11 is provided around the optical fiber 12. This structure allows an edge interface to be formed in the image captured by the optical fiber, thus facilitating the identification of the optical fiber's location.
[0056] Preferred solutions include Figure 1 In the process, the focused curing laser device 3 is installed at the bottom of the glue tank 2. Both the glue tank 2 and the glue are made of transparent material. Focused curing laser device 3 The focal point is located on the surface of the fiber ring 1 and tracks the winding position of the fiber 12. Positioned at the bottom of the adhesive tank 2, it ensures that the fiber 12 is cured at the point of contact with the fiber ring 1, preventing the fiber 13 from slipping and affecting the winding quality. The focused curing laser device 3 is typically kept as perpendicular as possible to the bottom of the adhesive tank 2 to minimize the impact of light refraction and reduce the need for design corrections to overcome refraction. This approach is preferred in this example.
[0057] Alternatively, in another alternative solution, the focused curing laser device 3 is located on one side of the adhesive tank 2, with its focal point positioned on the surface of the fiber ring 1 and tracking the winding position of the fiber 12. The advantage of this solution is its relatively simple laser device structure, which completely avoids the effects of light refraction. However, due to the distance between the fiber entry point (the initial contact point between the fiber and the fiber ring 1) and the curing point, there is a risk that the fiber 12 may slide on the surface of the fiber ring 1.
[0058] Preferred solutions include Figure 3 , 4In the focused curing laser device 3, the structure is as follows: a reflector 302 and a convex lens 303 are sequentially arranged in the optical path of the array laser 301 to converge multiple beams of light from the array laser 301 to a single point. In a preferred embodiment, an aperture is also provided between the array laser 301 and the reflector 302 to obtain a direct beam. Polarized light with the same phase is obtained through the reflector 302, allowing the beams to be converged and their power increased. The array laser 301 uses a low-power ultraviolet laser LED. The power of the array laser 301 is set such that a single laser beam is insufficient to cure the adhesive, requiring multiple beams; for example, 12 laser fibers converged can cure the adhesive within 0.2 to 0.5 seconds.
[0059] Preferred solutions include Figure 1 In this design, the focused curing laser device 3 is mounted on the mechanical gripper of the multi-axis robotic arm 5, and the focus is tracked by the movement of the gripper. This design allows the focused curing laser device 3 to use a fixed-focus approach, and this structure enables convenient focus tracking using the multi-axis robotic arm 5 without the need for a complex zoom mechanism.
[0060] Preferred solutions include Figure 5 In this invention, the optical fiber guide wheel 4 has a structure in which multiple first baffles 401 and second baffles 402 are radially staggered. Inclined surfaces are provided on opposite sides of the first baffles 401 and second baffles 402, and these inclined surfaces form a V-shaped groove 403. This structure allows for a precise V-shaped groove 403, especially at the bottom of the V-shape, as the diameter of the optical fiber is too small to easily produce a V-shaped structure with the required precision using cutting tools. The V-shaped groove 403 of this invention exhibits no misalignment when the optical fiber moves left or right.
[0061] Example 2:
[0062] like Figure 6 A control method using the aforementioned high-precision fiber optic winding system includes the following steps:
[0063] S1. Place the fiber optic ring 1 in the glue tank 2, with the bottom of the fiber optic ring 1 immersed in the glue in the glue tank 2.
[0064] S2. Fiber 12 is wound from the bottom of fiber ring 1 onto fiber ring 1. The second camera 7 is located on one side of glue tank 2 and takes images of fiber 12 and fiber ring 1. The position of fiber guide wheel 4 is controlled according to the images and fiber entry angle α so that fiber 12 is wound along the fiber entry angle α on the surface of fiber ring 1.
[0065] The second camera 7 is a fixed camera. During calibration, a reference position is set in the image, and the specific position of the optical fiber 12 is calculated based on the vector distance between the reference position and the optical fiber, combined with the pixels of the image.
[0066] The specific steps are as follows: S201, binarize the image to obtain the specific position of the optical fiber 12 in the image. Preferably, a straight line parallel to the axis outside the final turn of the optical fiber ring is used as the reference line, and the intersection of the line with the center line of the optical fiber ring 1 is used as the reference point. S202, calculate the current turn layer of the optical fiber ring 1 based on the distance between the outer surface of the bottom layer of the optical fiber ring 1 and the reference line. Calculate the coordinates of the fiber entry point based on the distance between the fiber entry point and the reference point, and calculate the number of turns and the extension normal of the current optical fiber ring. Calculate the target position of the optical fiber guide wheel 4 using the extension normal and the fiber entry angle α. Then, the main control device, such as a PLC, controls the transverse movement mechanism 10 to move the optical fiber guide wheel 4 into position. This allows the optical fiber guide wheel 4 to simulate manual winding of the optical fiber 12.
[0067] S3, such as Figure 7 In this configuration, the focal point of the focused curing laser device 3 is concentrated within a certain distance after the optical fiber 12 contacts the optical fiber ring 1. In a preferred embodiment, the focal point of the focused curing laser device 3 moves a certain distance following the rotation of the optical fiber ring 1, thereby obtaining a sufficiently long curing time to ensure the curing effect. In this example, an intermittent point curing scheme is used, with curing points set at intervals of 3-10 mm. After curing one point, the focused curing laser device 3 returns to the next curing point.
[0068] Through the above steps, high-precision fiber optic winding is achieved.
[0069] Preferred solutions include Figure 7 In step S3, the focused curing laser device 3 is set on the mechanical gripper of the multi-axis robotic arm 5. The beam of the array laser 301 will only cure the glue after it converges, and the beam will not cure the glue while passing through the glue.
[0070] The first camera 6 or the second camera 7 acquires images of the fiber optic ring 1. Based on the images of the fiber optic ring 1, the position of the current turn is identified, the elevation of the current turn is calculated, and the focal point position that needs to be solidified between the fiber optic cable 12 and the fiber optic ring 1 is calculated. Since the first camera 6 is a moving camera mounted on the mechanical gripper of the multi-axis robotic arm 5, the position of the solidification point is obtained from the image acquired by the second camera 7, the fiber entry point, and the angle of rotation of the fiber optic ring skeleton 81 driven by the winding drive device 8. The first camera 6 is mainly used to correct the movement error of the multi-axis robotic arm 5 and to provide feedback on the actual position of the multi-axis robotic arm 5.
[0071] The focal point of the focused curing laser device 3 is aligned with the calculated focal point position to be cured. The array laser 301 of the focused curing laser device 3 emits pulsed laser light, which is then focused to complete the curing operation of the optical fiber 12.
[0072] Preferred solutions include Figure 8The process also includes step S4, in which a lifting wedge 102 is set at each lifting position of the fiber ring 1 to prevent the fiber 12 from being squeezed and deformed at each lifting position.
[0073] The specific steps are as follows: S401, the first camera 6 or the second camera 7 acquires images of the fiber optic ring 1;
[0074] S402, Identify the current turn position of fiber optic cable 12;
[0075] S403. Calculate the current turn elevation and the rise angle position. The rise angle position refers to the position of the current turn fiber in terms of angle and axis when it rises to the next layer. The axial position can be obtained by the baffle of the fiber ring frame 81, that is, the position leaning against the inner side of the baffle of the fiber ring frame 81. However, the angular position is more difficult to obtain. In this example, the distance between the current turn's fiber 12 position and the inner side of the baffle of the fiber ring skeleton 81 is obtained by identifying the distance. If the calculated distance between the current turn's fiber and the inner side of the baffle is exactly an integer, then this position is the end point of the lifting wedge 102. Based on the length of the lifting wedge 102, a turning angle is calculated in reverse using trigonometric functions, which is the starting point of the lifting wedge 102. The focused curing laser device 3 is moved to this position in advance, and a long strip-shaped lifting wedge 102 is obtained through focused curing. The accuracy requirement of the starting point of the lifting wedge 102 is not high, while the accuracy requirement of the ending point is high. The thickness of the starting point of the lifting wedge 102 is thinner, and the thickness of the ending point is flush with the height of the current turn's fiber 12.
[0076] S404. The focal point of the focused curing laser device is aligned with the rise-layer corner position, and the rise-layer wedge 102 is generated by curing, so that the optical fiber 12 can rise to the next layer without deformation.
[0077] After the fiber optic ring is fabricated, it is placed in a centrifuge to spin off the glue, and then cured again to obtain a high-precision fiber optic ring 1.
[0078] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The embodiments and features described in these embodiments can be arbitrarily combined without conflict. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
