Description

Technical Field

[0002] The automatic winding equipment for hydrophone sensor cables is mainly used for the preparation of hydrophone sensor cables. Hydrophone sensor cables are also called acoustic sensitive optical cables. They are mainly used for the transmission of underwater monitoring signals in the ocean. Since hydrophone sensor cables have strong anti-interference ability and are not affected by changes in ambient temperature, they have been used more and more widely in recent years. Hydrophone sensor cables have the advantages of simple structure, wide detection range, and strong anti-interference ability, and have the trend of replacing traditional sonar buoys. The structure of hydrophone sensor cables usually uses a long-line cylindrical elastic body as the supporting mandrel, and a spiral special optical fiber is wound around the outer side of the supporting mandrel, and finally a cable protection sleeve is put on. Traditional hydrophone sensor cables are made manually, with poor consistency, low precision, and low production efficiency.

DETAILED DESCRIPTION

[0030] Embodiment 1: like Figure 1-5 In the invention, an automatic fiber winding device for a hydrophone sensing optical cable is provided, comprising an equipment platform 1, on which a clamping assembly 3 and a glue coating assembly 8 are provided, an optical fiber winding assembly 7 is provided between the clamping assembly 3 and the glue coating assembly 8, an elastic body 2 is provided with a clamping assembly 3 at one end, and the other end of the elastic body 2 is provided at the optical fiber winding assembly 7, a fiber release assembly 4 is also provided on the equipment platform 1, a guide wheel system is provided between the fiber release assembly 4 and the optical fiber winding assembly 7, the elastic body 2 moves along the length direction, and the optical fiber starts from the fiber release assembly 4, passes through the guide wheel system, reaches the optical fiber winding assembly 7, and is wound around the outer wall of the elastic body 2.

[0031] In the preferred embodiment, the fiber-releasing assembly 4 includes a rotatable fiber-releasing disk 403, the optical fiber winding assembly 7 includes a hollow shaft 2603, a rotatable rotating frame 26 is mounted on the hollow shaft 2603, the elastomer 2 passes through the central axis of the hollow shaft 2603, and the rotating frame 26 is provided with a second guide wheel group 25 eccentrically arranged to the central axis of the hollow shaft 2603, the clamping assembly 3 includes a rotatable lower guide wheel 11, the elastomer 2 is placed on the lower guide wheel 11, the lower guide wheel 11 drives the elastomer 2 to move in a straight line, and the optical fiber starts from the fiber-releasing disk 403, passes through the second guide wheel group 25 and is spirally wound on the elastomer 2.

[0032] The elastic body 2 is in the shape of a cylindrical long rod.

[0033] The optical fiber is wound on the fiber pay-off disk 403, and is released as the fiber pay-off disk 403 rotates. After being guided by the second guide wheel group 25, the other end is wound on the elastomer 2 as the rotating frame 26 rotates. Since the lower guide wheel 11 drives the elastomer 2 to move linearly, the optical fiber is spirally wound on the elastomer 2.

[0034] The rotating frame 26 includes a first rotating arm 2601 and a second rotating arm 2602 which are symmetrically arranged relative to the central axis of the hollow shaft 2603 . The second guide wheel group 25 is arranged on the first rotating arm 2601 , and a counterweight 21 is arranged on the second rotating arm 2602 .

[0035] The weight of the turntable driving motor 22 is determined according to the second guide wheel set 25 to improve the dynamic balance of the rotating frame 26 when rotating.

[0036] In the preferred embodiment, the guide wheel system includes a first guide wheel group 504 and a second guide wheel group 25. A rotatable transition disk 18 is provided between the first guide wheel group 504 and the second guide wheel group 25. The optical fiber is wound around the transition disk 18 from the fiber release disk 403, and then wound around the elastomer 2 through the second guide wheel group 25.

[0037] In the preferred embodiment, a second basic frame 401 is provided on the equipment platform 1, a limiting roller group 404 is provided on the second basic frame 401, a third basic frame 501 is provided between the fiber release assembly 4 and the optical fiber winding assembly 7, a rotatable outer cylinder 2801 is provided on the third basic frame 501, the outer cylinder 2801 is a hollow structure, a transition plate 18 is provided at one end of the outer cylinder 2801, an inner cylinder 2802 rotatable relative to the outer cylinder 2801 is provided in the outer cylinder 2801, and the end of the inner cylinder 2802 is connected to the rotating frame 26.

[0038] A through hole is provided in the third basic frame 501, and a first bearing 28 is installed at the hole mouth, and the outer cylinder 2801 is sleeved on the inner side of the first bearing 28 so that the first bearing 28 can rotate. Similarly, a second bearing 2803 is installed on the inner side of the outer cylinder 2801, and the inner cylinder 2802 is sleeved on the inner side of the second bearing 2803 so that the second bearing 2803 can rotate.

[0039] The outer cylinder 2801 drives the transition plate 18 to rotate, so that the optical fiber from the fiber-releasing disk 403 is wound on the transition plate 18 for a certain number of turns. The inner cylinder 2802 drives the rotating frame 26 to rotate, consumes the optical fiber buffered on the transition plate 18 and winds it around the elastic body 2.

[0040] In the preferred embodiment, the first guide wheel group 504 is arranged on the third basic frame 501, and a swing rod 503 hinged to the third basic frame 501 is provided in the center of the third basic frame 501, an encoder 502 is provided at the hinge, and a rotatable tension control component 5 is also provided at one end of the swing rod 503, and the optical fiber bypasses the tension control component 5 from below.

[0041] The first guide wheel group 504 includes a tension control component 5, an encoder 502, a swing rod 503, etc.

[0042] A fiber-releasing motor 402 is disposed on one side of the second basic frame 401 , and the fiber-releasing motor 402 drives the fiber-releasing disc 403 to rotate.

[0043] The limiting roller pair group 404 is two groups of parallel and spaced roller pairs arranged orthogonally, with a gap for the optical fiber to pass through in the middle.

[0044] The tension control assembly 5 presses down and tensions the optical fiber. When the optical fiber release speeds up, the tension control assembly 5 swings down. After the encoder 502 detects the rotation of the swing rod 503, the fiber release speed is slowed down, and the tension increases, causing the tension control assembly 5 to return to its original position. When the optical fiber release slows down, the tension control assembly 5 swings up. After the encoder 502 detects the rotation of the swing rod 503, the fiber release speed is accelerated, and the tension decreases, causing the tension control assembly 5 to return to its original position.

[0045] Since the fiber winding requires a large number of guide wheel systems, including the first guide wheel group 504 and the second guide wheel group 25, the traditional method is that all guide wheel systems rotate to wind the fiber. However, after the flip angle, the tensioning structure that requires gravity participation, such as the tension control component 5, will fail, and since the guide wheel is generally a V-shaped wheel and arranged on one side of the fiber, the fiber may fall out of the guide wheel after flipping when the tension is small.

[0046] By dividing the guide wheel system into two parts, namely, a limiting roller group 404, a first guide wheel group 504 and a second guide wheel group 25, and arranging a transition plate 18 in the middle to cache the optical fiber, it is possible to achieve the follow-up of only the second guide wheel group 25, thereby reducing the weight of the rotating mechanism, improving the reliability of the device, and reducing the cost of the drive motor.

[0047] In the preferred scheme, a transition disk drive motor 29 and a winding drive motor 30 are also provided on the third basic frame 501, and synchronous wheels are provided on the shaft ends of the transition disk drive motor 29 and the winding drive motor 30. The end of the outer cylinder 2801 is covered with a transition disk synchronous pulley 16, and the end of the inner cylinder 2802 is covered with a winding assembly synchronous pulley 17. The transition disk drive motor 29 drives the transition disk synchronous pulley 16 to rotate through a synchronous belt, and the winding drive motor 30 drives the winding assembly synchronous pulley 17 to rotate through a synchronous belt.

[0048] An elastomeric guide block 14 is provided on the side of the upper and lower guide wheels 11 of the first basic frame 301 away from the optical fiber winding assembly 7. The elastomer 2 passes through the elastomeric guide block 14. A positioning sleeve 27 can be provided on the inner side of the end of the hollow shaft 2603. The positioning sleeve 27 is provided with a sliding bushing, which is sleeved on the elastomer 2.

[0049] One end of the elastomer 2 passes through the elastomer guide block 14 and is supported by the lower guide wheel 11, and the other end is supported by the positioning sleeve 27 to ensure that the elastomer 2 is coaxial with the rotating axis of the rotating frame 26 to prevent the elastomer 2 from eccentric rotation. The positioning sleeve 27 is close to the optical fiber winding position to prevent the elastomer 2 from falling due to a long distance.

[0050] In this way, for elastic bodies 2 of different diameters, it is necessary to replace the elastic body guide block 14 and the positioning sleeve 27 of different diameter specifications.

[0051] In a preferred embodiment, the clamping assembly 3 includes a first basic frame 301, on which a first movable plate 302 and a second movable plate 306 that can move up and down are provided, a lower guide wheel 11 is provided on the first movable plate 302, and a rotatable upper pressing wheel 10 is provided on the second movable plate 306, the upper pressing wheel 10 and the lower guide wheel 11 move relative to each other to clamp the elastic body 2, a plurality of outer petal sleeves 2701 are provided along the circumferential direction at the end of the hollow shaft 2603, and each outer petal sleeve 2701 is provided with a slidable inner slider 2702, Both the outer petal sleeve 2701 and the inner slider 2702 are provided with a slope surface 2705, and the slope surfaces 2705 of the outer petal sleeve 2701 and the inner slider 2702 are in contact with each other. One end of the outer petal sleeve 2701 is provided with an extension base plate 2706, and the extension base plate 2706 is provided with a threaded adjustment screw 2703, one end of the adjustment screw 2703 is rotatably connected to the inner slider 2702, and the inner slider 2702 is provided with a rotatable V-shaped abutment wheel 2704, which abuts against the outer wall of the elastomer 2.

[0052] A clamping cylinder 9 is also provided on the first basic frame 301 , and a cylinder rod end of the clamping cylinder 9 is connected to the second movable plate 306 . The clamping cylinder 9 drives the upper pressing wheel 10 to press the upper part of the elastic body 2 .

[0053] The outer petal sleeve 2701 is provided with a dovetail groove, and the inner slider 2702 is provided with a dovetail protrusion 2711 , and the dovetail protrusion 2711 is slidably engaged with the inner slider 2702 .

[0054] The contact surface between the V-shaped abutment wheel 2704 and the elastomer 2 is provided with a sliding coating 2707 to improve the wear resistance and reduce the friction between the V-shaped abutment wheel 2704 and the outer wall of the elastomer 2 when the hollow shaft 2603 rotates relative to the elastomer 2.

[0055] The inner slider 2702 is provided with a connecting sleeve 2708, and an annular groove 2710 is provided on the outer wall near the end of the adjusting screw 2703. A threaded top screw 2709 is provided on the connecting sleeve 2708. One end of the top screw 2709 passes through the connecting sleeve 2708 and is inserted into the annular groove 2710. However, it is a clearance fit, which only limits the displacement of the adjusting screw 2703 in the length direction and does not affect its rotation.

[0056] When the diameter of the elastomer 2 changes, the height of the first movable plate 302 can be adjusted to ensure that one end of the elastomer 2 is on the axis of the hollow shaft 2603, and the adjusting screw 2703 is rotated to adjust the position of the inner slider 2702. Due to the slope surface 2705, the V-shaped abutment wheels 2704 of each inner slider 2702 will approach or move away from each other radially in the hollow shaft 2603. The V-shaped abutment wheels 2704 are adjusted to a suitable distance to make the other end of the elastomer 2 on the axis of the hollow shaft 2603, so that the elastomer 2 and the hollow shaft 2603 are finally coaxial.

[0057] In the preferred solution, a vertical plate 303 is provided on the first basic frame 301, and a plurality of threaded abutment screws 304 are provided on the vertical plate 303, and the upper ends of the abutment screws 304 abut against the lower end of the first movable plate 302, and a plurality of waist-shaped grooves 305 are provided on the first movable plate 302, and bolts pass through the waist-shaped grooves 305 to press the first movable plate 302 onto the first basic frame 301.

[0058] In the preferred solution, a clamping motor 15 is further provided on the first movable plate 302 , and a clamping synchronous pulley 12 is provided on the shaft ends of the clamping motor 15 and the lower guide wheel 11 , and a synchronous toothed belt 13 is also provided. The clamping motor 15 drives the lower guide wheel 11 to rotate via the synchronous toothed belt 13 .

[0059] Since the rotating shaft of the lower guide wheel 11 needs to move up and down, a space-avoiding portion needs to be provided on the first basic frame 301 .

[0060] A second movable plate 306 which can move up and down is provided on the first basic frame 301, and a plurality of upper pressure wheels 10 arranged side by side are provided on the second movable plate 306, and a plurality of lower guide wheels 11 are also provided. The cylinder rod of the clamping cylinder 9 is connected to the second movable plate 306 through a connecting block. The clamping cylinder 9 drives the second movable plate 306 to descend to press the elastomer 2, thereby ensuring appropriate friction force to drive the elastomer 2 forward and prevent slipping.

[0061] The remaining lower guide wheels 11 can form a linkage mechanism through a synchronous belt and a pulley, and the first basic frame 301 drives each lower guide wheel 11 to rotate synchronously.

[0062] In the preferred embodiment, the glue coating component 8 includes a rotating platform 23, the center of the rotating platform 23 is hollow, and a plurality of rotatable roller brushes 24 are arranged circumferentially on the rotating platform 23. The elastomer 2 passes through the center of the rotating platform 23, and the outer wall of the roller brush 24 is in contact with the outer wall of the elastomer 2.

[0063] The glue coating component 8 includes an L-shaped bracket, and a rotating platform 23 is installed on the L-shaped bracket. A turntable drive motor 22 is also provided on one side of the rotating platform 23 on the L-shaped bracket. The turntable drive motor 22 can drive the rotating flange of the rotating platform 23 to rotate through a gear or a synchronous belt mechanism. A connecting ear 2401 with a strip hole is provided on one side of the roller brush 24, which is locked on the rotating flange of the rotating platform 23 by screws.

[0064] The roller brush 24 is dipped with glue. When the elastomer 2 moves linearly, the rotating platform 23 drives each roller brush 24 to rotate around the central axis of the rotating platform 23. The roller brush 24 rolls on the outer wall of the elastomer 2 and applies glue to the elastomer 2 and the spiral optical fiber.

[0065] Embodiment 2: An elastic body clamping and optical fiber winding mechanism comprises an equipment platform 1, an elastic body 2, a clamping assembly 3, a fiber release assembly 4, a tension control assembly, an optical fiber transition assembly 6, an optical fiber winding assembly 7, and a glue coating assembly 8.

[0066] The device platform 1 is the installation base for all components and integrates various functional components into one.

[0067] The clamping and conveying assembly 3 is mainly used to clamp the elastic body 2 and drive the elastic body to move forward in a straight line by the rotation of the guide wheel. The guide wheel is precisely controlled by the servo motor 15 to control the displacement speed of the elastic body 2.

[0068] The fiber release assembly 4 is mainly used to install the optical fiber source disk, providing an optical fiber source for winding the optical fiber on the elastic body 2. The shaft on which the optical fiber source disk is installed is controlled to rotate by a servo motor, driving the optical fiber source disk to release the optical fiber.

[0069] The tension control component is mainly used to control the tension of the optical fiber wound onto the intermediate transition disk 18 to prevent the optical fiber from being broken due to excessive tension when it is wound onto the transition disk 18. The speed of the fiber-releasing component 4, the optical fiber transition disk 18, and the tension control component 5 are controlled by PLC for PID regulation, ensuring that the optical fiber is wound onto the elastomer 2 with a stable tension.

[0070] The main function of the optical fiber transition assembly 6 is to temporarily store the wound optical fiber. The optical fiber on the optical fiber source disk passes through the tension control assembly 5 and is wound on the transition disk 18. The optical fiber on the transition disk 18 is then spirally wound on the elastomer 2 through the optical fiber winding assembly 7. The transition disk 18 and the optical fiber winding assembly 7 are respectively controlled to rotate by servo motors for the retraction and tension control of the optical fiber.

[0071] The optical fiber winding assembly 7 is mainly used to control the spiral winding of the optical fiber onto the elastic body 2, and can control the winding tension of the optical fiber. The optical fiber winding assembly 7 is controlled to rotate by a servo motor, and the optical fiber transition plate 18 and the optical fiber winding assembly 7 are controlled by PLC to perform PID to adjust the optical fiber winding speed.

[0072] In this case, the clamping and conveying component 3, the fiber-releasing component 4, the tension control component, the optical fiber transition component 6, the optical fiber winding component 7, and the glue coating component 8 are all integrated on the equipment platform 1, with high overall integration, modular design and assembly, which is convenient for equipment maintenance.

[0073] The working principle is as follows: first, the clamping assembly 3 causes the upper pressure wheel 10 to clamp the elastic body 2 under the action of the clamping cylinder 9, and the servo motor 15 drives the lower guide wheel 11 to rotate under the transmission of the synchronous pulley 12 and the synchronous toothed belt 13, and the lower guide wheel 11 will drive the elastic body 2 to move in a uniform linear motion.

[0074] The fiber release assembly 4 drives the fiber release source disc to release the optical fiber, and the optical fiber is wound on the optical fiber transition disc 18 after passing through the tension control assembly. At the same time, the guide wheel 19 and the tension sensor wheel 20 on the optical fiber winding assembly 7 on the optical fiber transition disc 18 are wound on the elastic body 2. At this time, the optical fiber winding assembly 7 rotates around the elastic body 2, and the elastic body 2 moves linearly at the same time, so the optical fiber can be spirally wound on the elastic body with a certain tension.

[0075] The elastomer with the optical fiber wound around it passes through the glue coating assembly 8, and the servo motor 22 drives the rotating platform 23 to rotate. The rotating platform 23 drives the roller brush 24 to rotate around the elastomer 2. The roller brush 24 is supplied with ultraviolet glue. A layer of ultraviolet glue will be evenly coated on the elastomer 2 and the optical fiber. After subsequent ultraviolet curing, the optical fiber and the elastomer will be cured and shaped. The optical fiber is spirally wound and shaped on the elastomer.

[0076] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
