Description

Technical Field

[0001] This invention relates to the field of optical fiber winding, and in particular to a series optical fiber winding device. Background Technology

[0002] An optical fiber ring is an optical device made by winding special optical fiber materials into a ring structure according to relevant volume, optical, and vibration requirements using specialized optical fiber winding equipment (ring winding machine), through special winding methods, curing processes, and adhesives. There are various types of optical fiber rings, which can be used in components such as fiber optic gyroscopes and hydrophones. Hydrophones are components that convert underwater acoustic vibration signals into optical signals. They possess characteristics such as small size, high strength, high reliability, low loss, moisture resistance, salt resistance, and high pressure resistance; therefore, the structure of their optical fiber rings must also be small in size.

[0003] For an example of a fiber optic hydrophone, please refer to application number 202210311805.2, entitled "A Symmetrical Time-Division Multiplexing Structure and a High-Reliability Fiber Optic Hydrophone Array System". Due to the special structure of the hydrophone, a narrow and long fiber optic loop, different from that used in fiber optic gyroscopes, is required. Therefore, the corresponding fiber optic loop skeleton is also quite special, being a thin shaft. Because of its small diameter, this fiber optic loop skeleton cannot be fitted onto the outside of the rotating shaft; therefore, a special fiber take-up assembly structure is required.

[0038] Example 1:

[0039] like Figure 1-20 In a series optical fiber winding device, there is a frame body 6, the frame body 6 is provided with a platform 601, the platform 601 is provided with a translation slide assembly 11, the translation slide assembly 11 is provided with a fiber feeding assembly 8, an adhesive application assembly 10 and a fiber optic rod assembly 12, a fiber take-up mechanism 1 and a skeleton end connection assembly 2 are provided on one side of the translation slide assembly 11, the fiber take-up mechanism 1 is provided with a rotatable fiber take-up drive shaft 101, one end of the fiber take-up drive shaft 101 is connected to one end of the optical fiber ring skeleton 7, and the skeleton end connection assembly 2 is connected to the other end of the optical fiber ring skeleton 7.

[0040] The fiber feeding assembly 8 is equipped with a fiber feeding wheel 801 and a fiber feeding motor 802. The fiber feeding motor 802 drives the fiber feeding wheel 801 to rotate and feed the fiber.

[0041] A guide wheel assembly 9 is provided between the fiber laying assembly 8 and the adhesive coating assembly 10. The guide wheel assembly 9 consists of multiple fixed pulleys used in conjunction to change the direction of the optical fiber. The guide wheel assembly 9 is equipped with a tension adjustment wheel to adjust the position and change the tension of the optical fiber.

[0042] The fiber optic rod assembly 12 consists of multiple adjustable rods with adjustable positions and angles. The rods have multiple mounting holes to adjust their relative positions. The outermost rod end is semi-cylindrical and fits snugly against the outer wall of the optical fiber.

[0043] The fiber take-up mechanism 1 includes a fiber take-up mechanism base 105, a fiber take-up drive motor 104 is provided on the fiber take-up mechanism base 105, a synchronous pulley 102 is provided at the end of the fiber take-up drive shaft 101 and the fiber take-up drive motor 104, and a synchronous belt 103 is also provided. The fiber take-up drive motor 104 and the fiber take-up drive shaft 101 are driven by the synchronous belt 103.

[0044] In a preferred embodiment, the adhesive application assembly 10 includes an adhesive storage cylinder 1002, with an adhesive application head 1001 at one end of the adhesive storage cylinder 1002. The adhesive application head 1001 is aligned with the outer wall of the optical fiber. A slidable piston 1003 is provided inside the adhesive storage cylinder 1002. A piston external bracket 1004 is provided at one end of the piston 1003. A linear moving stage 1005 is also provided. The linear moving stage 1005 drives the piston 1003 to move through the piston external bracket 1004 to squeeze adhesive from the adhesive application head 1001.

[0045] The translation slide assembly 11 and the linear motion stage 1005 are servo linear motion modules. The internal servo motor drives the lead screw or synchronous belt to drive the guide rail slider assembly, thereby pushing the sliding plate to move. The piston external bracket 1004 is installed on the sliding plate of the linear motion stage 1005. The fiber feeding assembly 8, guide wheel group 9, glue application assembly 10 and fiber wicking rod assembly 12 are installed on the sliding plate of the translation slide assembly 11.

[0046] In a preferred embodiment, the guide wheel assembly 9 includes a vertical plate with multiple fixed pulleys 901 and a rotatable rotating arm 902. One end of the rotating arm 902 has an abutment wheel 903, and an optical fiber passes around the fixed pulleys 901 and the abutment wheel 903. The other end of the rotating arm 902 has a counterweight 904. The rotating arm 902 has multiple hinge holes arranged in a straight line, and an encoder is located at the shaft of the rotating arm 902.

[0047] When installing the rotating arm 902, select the hinge hole position according to the required fiber tension. The abutment wheel 903 presses on the fiber. The encoder monitors the rotation angle of the rotating arm 902 in real time. If the angle of the rotating arm 902 increases or decreases, it indicates that the fiber tension has changed. The speed of the fiber feeding wheel 801 is adjusted immediately to make the rotating arm 902 return to balance.

[0048] During the winding process, the optical fiber starts from the fiber feeding wheel 801, changes direction and adjusts tension after passing through the guide wheel group 9, and is then coated with glue by the glue applicator head 1001. After the fiber take-up mechanism 1 and the frame end connecting assembly 2 fix the two ends of the optical fiber ring frame 7, the optical fiber end is wound around the optical fiber ring frame 7, the fiber take-up drive shaft 101 starts to rotate, the end of the fiber aligning rod assembly 12 is located near the optical fiber ring frame 7, and the semi-cylindrical end abuts against the outer wall of the optical fiber to apply fiber aligning force. As the driving sliding plate of the translation slide assembly 11 moves, the end of the fiber aligning rod assembly 12 begins to align the fiber to one side. After one layer of fiber aligning is completed, the glue gradually solidifies. Then, the angle position of the fiber aligning rod assembly 12 is adjusted to start the second layer of fiber aligning.

[0049] In a preferred embodiment, the fiber optic ring frame 7 includes a first frame 701 and a second frame 702. A frame connecting rod 703 is provided between the first frame 701 and the second frame 702. One end of the fiber take-up drive shaft 101 is provided with a first connecting fastening device, which is connected to the first frame 701. The frame end connecting assembly 2 includes a clamping assembly base 202. A clamping assembly moving slide 3 is provided below the frame end connecting assembly 2. The clamping assembly moving slide 3 is provided with a slidable sliding table 301. The clamping assembly base 202 is connected to the sliding table 301. A slidable extension shaft 203 is provided inside the clamping assembly base 202. A rotatable second connecting fastening device is provided at the end of the extension shaft 203, which is connected to the second frame 702.

[0050] The base 202 of the clamping assembly is provided with a bushing 204, which is made of ceramic or copper and contacts the outer wall of the extension shaft 203.

[0051] The first connection and fastening device can be an optical fiber ring skeleton connector 5, which is a conventional connection structure such as a screw, screw sleeve or clamp, connecting the optical fiber ring skeleton 7 and the fiber take-up drive shaft 101 as one unit.

[0052] The second connecting and fastening device can be a top cone 4, which is used to tighten the other end of the fiber optic ring frame 7.

[0053] In the case of two fiber optic rings connected in series, a frame connecting rod 703 is provided between the first frame 701 and the second frame 702. The two ends of the frame connecting rod 703 are fixedly connected to the first frame 701 and the second frame 702 to form a fiber optic ring frame 7.

[0054] During fiber winding, one end of the fiber ring frame 7 is mounted on the fiber ring frame connector 5. There are two modes at this time. The first mode is serial winding, in which the first frame 701 and the second frame 702 are connected by the frame connecting rod 703. The sliding table 301 drives the frame end connecting component 2 to approach the fiber take-up mechanism 1. The top cone 4 presses against the other end of the fiber ring frame 7. The fiber take-up drive shaft 101 rotates. The fiber is wound alternately on the first frame 701 and the second frame 702, or the first frame 701 is wound first and then the second frame 702 is wound.

[0055] In a preferred embodiment, a clamping spring 205 is also provided inside the clamping component base 202, with one end of the clamping spring 205 abutting against the extension shaft 203.

[0056] The clamping component base 202 is provided with a stepped shaft 213, which is sleeved with the clamping component base 202, and one end of the clamping spring 205 abuts against the shoulder of the stepped shaft 213.

[0057] The clamping spring 205 applies a holding force to the top extension shaft 203, so that the top cone 4 can continuously and stably hold the fiber optic ring skeleton 7.

[0058] In a preferred embodiment, the clamping component base 202 is provided with a box structure 201, a gear 207 is provided inside the box structure 201, and a slidable rack 206 is also provided inside the clamping component base 202. One side of the rack 206 meshes with the gear 207, and the other side of the rack 206 is connected to the top extension shaft 203. A gear drive shaft 211 is provided in the center of the gear 207.

[0059] The gear drive shaft 211 can be connected to a servo motor or rotated manually. When the gear drive shaft 211 is connected to a motor, the pressing component moving slide 3 is a servo slide, which is driven by a drive motor and a lead screw mechanism or a synchronous belt mechanism to move the slide 301 precisely.

[0060] In a preferred embodiment, the gear drive shaft 211 has a handle 212 at its end, and a locking buckle 208 is provided on one side of the gear 207. One end of the locking buckle 208 is used to lock the teeth of the gear 207. The housing structure 201 has a strip groove 210, and a locking buckle locking screw 209 is provided in the strip groove 210. The locking buckle locking screw 209 passes through the strip groove 210. One end of the locking buckle locking screw 209 is sleeved with the locking buckle 208 and threadedly connected to the side wall of the housing structure 201. The other end of the locking buckle locking screw 209 presses against the other side wall of the housing structure 201. The top clamping assembly moving slide 3 includes a slide base plate and a guide rail slider mechanism 303. The slide 301 is connected to the slide base plate through the guide rail slider mechanism 303. A manual guide rail clamp 302 is provided on the guide rail slider mechanism 303.

[0061] When manually adjusting the ring frame for tightening, first loosen the manual guide clamp 302, slide the sliding table 301 until the top cone 4 is close to the end of the fiber optic ring frame 7, lock the manual guide clamp 302, unlock the locking screw 209, and the locking buckle 208 moves along the length of the slot 210 and is pulled out from the teeth of the gear 207. Grasp the handle 212 to rotate the gear 207, causing the rack 206 to move horizontally. The rack 206 is integrated with the top extension shaft 203 via the connecting mounting block, thus extending the top extension shaft 203 forward, causing the top cone 4 to press against the end of the fiber optic ring frame 7 and compress the tightening spring 205. Then, reinsert the locking buckle 208 into the teeth and rotate the locking screw 209, re-locking the gear 207 and the top extension shaft 203.

[0062] The fiber optic ring frame 7 is actually composed of two single-ring first frame 701 and second frame 702, plus the distance of the intermediate frame connecting rod 703. Due to the small diameter of the fiber optic ring frame 7's shaft, deformation will occur in the center during winding due to the tight connection at both ends of the fiber optic ring frame 7, affecting the winding accuracy. In addition, after each one is wound, the machine needs to be stopped to cut the fiber, remove the wound fiber ring, install a new fiber optic ring frame 7, and then rewind the broken fiber end onto the new fiber optic ring frame 7. After the fiber is cut, it will naturally droop, so when rewinding at the break point, it is also necessary to find the fiber end. Therefore, the automation of the fiber cutting device is difficult, and this process is generally done manually. These operations restrict the timing and quality of automated winding.

[0063] Therefore, in the preferred embodiment, the fiber take-up drive shaft 101 is provided with a hollow through hole 106, and a first clamping device 14 is provided at one end of the hollow through hole 106 near the end of the skeleton end connecting component 2. The fiber take-up mechanism 1 is provided with a push slide 1303 on the side away from the end of the skeleton end connecting component 2. A movable push shaft 13 is provided on the push slide 1303. The central axis of the push shaft 13 is aligned with the central axis of the hollow through hole 106. The push extension shaft 203 is provided with a central through channel 215, and the second clamping device 15 is rotatable.

[0064] At this time, the first connecting fastening device is the first clamping device 14, and the second connecting fastening device is the second clamping device 15.

[0065] A bearing device is provided at the connection between the second clamping device 15 and the top extension shaft 203.

[0066] The original position of the top cone 4 inside the top extension shaft 203 is replaced by a cone bushing 214, which has a cylindrical through hole inside.

[0067] The push shaft 13 has a hollow through cavity 1301 inside. One end of the hollow through cavity 1301 has a detachable cover 1302. Multiple fiber optic ring frames 7 can be connected in series. Since the series structure of multiple fiber optic ring frames 7 is relatively long, after the cover 1302 is removed, the series structure of multiple fiber optic ring frames 7 is inserted into one end of the hollow through cavity 1301 and passes out from the other end and is inserted into the synchronous belt 103. When the front end of the series structure of multiple fiber optic ring frames 7 is inserted into the central through channel 215, the rear end has been pulled out from the hollow through cavity 1301. At this time, the cover 1302 is installed. The end of the cover 1302 can push the series structure of multiple fiber optic ring frames 7, which plays the role of a feeding mechanism.

[0068] Since each skeleton connecting rod 703 and extension connecting rod assembly 705 is equipped with a positioning sleeve 704, only half of the fiber optic ring skeleton 7, i.e., the first skeleton 701 or the second skeleton 702, needs to be exposed for winding each time. After winding, the series structure of multiple fiber optic ring skeletons 7 is shifted by half the length of the fiber optic ring skeleton 7, and then the other half is wound. The distance between the first clamping device 14 and the second clamping device 15 is nearly half that of the double-clamping fixing mode, further reducing skeleton deformation. Moreover, multiple fiber optic ring skeletons 7 can be wound continuously without stopping to change skeletons, improving winding efficiency. Furthermore, after the fiber is wound on one fiber optic ring skeleton 7, it does not need to be cut and can be directly wound on the next fiber optic ring skeleton 7 until the series structure of multiple fiber optic ring skeletons 7 is completely wound. Then, the fiber is cut at each extension connecting rod assembly 705. Multiple series fiber optic rings can be wound automatically at once, greatly improving efficiency.

[0069] The push slide 1303 can be a screw-rail-servo motor type slide structure or a synchronous belt-rail-servo motor type slide structure.

[0070] In a preferred embodiment, an extension connecting rod assembly 705 is provided between multiple fiber optic ring skeletons 7. A positioning sleeve 704 is fitted in the middle of the skeleton connecting rod 703 and the extension connecting rod assembly 705. Two opposing first inner cone blocks 706 are provided at both ends of the outer wall of the positioning sleeve 704. The first clamping device 14 and the second clamping device 15 both include a base block 1401 with a central through hole. The base block 1401 is provided with multiple radial grooves 1402 along the circumference. Each radial groove 1402 is provided with a slidable sliding tongue 1403. The sliding tongue 1403 is provided with an oblique groove 1404. A rotatable external gear ring 1405 is provided in the center of the base block 1401. Multiple outwardly extending levers 1406 are provided on the external gear ring 1405 along the circumference. Each lever 1406 is inserted into each oblique groove 1404. The sliding tongue 1403 clamps the fiber optic ring skeleton 7 towards the center of the central through hole of the base block 1401.

[0071] The end of the extension connector assembly 705 has a stop 708 that can abut against the end of the fiber optic ring frame 7.

[0072] The outer gear ring 1405 is also provided with a drive gear 1407 meshing with it. The drive gear 1407 is driven by the gear drive motor 1408 and drives the outer gear ring 1405 to rotate. The outer gear ring 1405 drives the lever 1406 to rotate. The lever 1406 slides in the inclined groove 1404 to generate an oblique thrust, which causes the sliding tongue 1403 to clamp the positioning sleeve 704 of the skeleton connecting rod 703 inward. The chamfered edge of the sliding tongue 1403 abuts against the first inner cone block 706. The inner wall of the positioning sleeve 704 can be provided with a friction layer such as a rubber layer to firmly hold the outer wall of the skeleton connecting rod 703.

[0073] When the first clamping device 14 and the second clamping device 15 clamp, the series structure of multiple fiber optic ring frames 7 winds the fiber as the fiber take-up drive shaft 101 rotates. When the first clamping device 14 and the second clamping device 15 are released, the series structure of multiple fiber optic ring frames 7 can move laterally as a whole.

[0074] In a preferred embodiment, a second clamping device 15 is provided at one end of the through-hole channel 215 near the fiber take-up mechanism 1, and an auxiliary rod disassembly device 16 is provided at the other end of the through-hole channel 215 away from the fiber take-up mechanism 1. Sliding axial telescopic rods 707 are provided at both ends of the extended connecting rod assembly 705, with a conical surface 711 at the end of each axial telescopic rod 707. Multiple radial telescopic rods 709 are provided circumferentially at both ends of the extended connecting rod assembly 705, with a wedge-shaped surface 712 at one end of each radial telescopic rod 709. The conical surface 711 abuts against the wedge-shaped surface 712. One end of the 2 is provided with a compression spring 713, which abuts against the axial telescopic rod 707. The ends of the first frame 701 and the second frame 702 are provided with countersunk hole structures, and the sidewalls of the countersunk hole structures are provided with positioning slots 710. The other end of the radial telescopic rod 709 is inserted into the positioning slots 710. The axial telescopic rod 707 is provided with two opposing second inner cones 714 near the center of the extension connecting rod assembly 705. The structure of the auxiliary rod removal device 16 is the same as that of the first clamping device 14 and the second clamping device 15. The sliding tongue 1403 of the auxiliary rod removal device 16 abuts against the second inner cones 714.

[0075] The outer wall of the extension connecting rod assembly 705 is provided with a through sliding groove on the moving path of the second inner cone block 714.

[0076] The auxiliary rod removal device 16 has the same structure as the first clamping device 14 and the second clamping device 15, but is wider. The sliding tongue 1403 of the auxiliary rod removal device 16 is also wider. A clearance groove is provided in the center of the clamping end of the sliding tongue 1403 of the auxiliary rod removal device 16 to avoid the structure of the positioning sleeve 704.

[0077] After the fiber optic ring skeleton 7 at the front end is wound and passes through the central through-hole channel 215, the sliding tongue 1403 of the auxiliary rod dismantling device 16 retracts to clamp the second inner cone block 714. The second inner cone block 714 drives the axial telescopic rod 707 to move outward. The cone surface 711 presses against the wedge surface 712 and compresses the compression spring 713. The radial telescopic rod 709 retracts inward and is pulled out from the positioning slot 710.

[0078] The auxiliary rod removal device 16 has the same structure as the first clamping device 14 and the second clamping device 15, but different functions. The auxiliary rod removal device 16 assists in the quick unlocking of the extension connecting rod assembly 705 and the fiber optic ring skeleton 7. The skeleton connecting rod 703 is an inherent structure of the fiber optic ring skeleton 7, but the extension connecting rod assembly 705 can be removed and reused.

[0079] Example 2:

[0080] An optical fiber winding structure is provided, which can guide the optical fiber path during winding by setting the optical fiber length. Without human intervention, the optical fiber can maintain a set tension during winding. During the winding process, the fiber distribution disc rotates at a set speed, and the active clamping wheel delivers the optical fiber at a matching speed. At the same time, the optical fiber behind the fiber guide wheel is glued and cured. The receiving assembly winds the glued optical fiber onto the frame.

[0081] It includes a device frame, touch screen assembly, display assembly, clamping assembly, fiber feeding assembly, fiber taking assembly, camera assembly, and guide + clamping + dispensing assembly. It has a high degree of integration, a modular structure, and high control precision.

[0082] The equipment frame is primarily used for the overall appearance of the equipment and as a platform to support the entire internal structure.

[0083] The touchscreen component is mainly used for various online operations of the equipment, while displaying various parameters and equipment operating status in real time. Important data can be saved and recorded. The display component is mainly used to clearly display the fiber winding status. The clamping component clamps the other side of the frame for easy fiber take-up. The fiber aligning component is mainly used for fiber aligning on the fiber optic coil. The fiber take-up component uses a servo motor to drive the frame at a stable take-up speed according to the set take-up speed. The camera component is mainly used for image monitoring. The guide + clamping + dispensing component guides the fiber winding path. The tension adjustment structure maintains stable tension transmission of the fiber during winding, and adjusting the position of the counterweight adjusts the fiber tension. The photoelectric encoder feeds back the angle position value of the buffer wheel to the system, which adjusts the speed of the fiber feeding component in real time to ensure stable fiber transmission. The dispensing component controls the amount of glue dispensed from the glue cylinder through a precision servo module. When winding stops, the servo simultaneously stops the glue output. The dispensing component includes a dispensing module, glue cylinder, and brush. The glue is generally AB grade. The adhesive is mixed, and the fiber optic clamping function is automatic. When it is necessary to replace the winding frame, the electric gripper will automatically clamp the fiber. When the next frame starts to be wound, the clamping can be released.

[0084] The servo motor in the fiber feeding assembly drives the fiber distribution disk to rotate and feed the fiber. The fiber is wound according to the fiber path, with adhesive applied during the winding process. The fiber is wound onto the frame, the winding length is set, and the winding is complete. If different frame windings are needed, simply remove the clamps holding the frame and replace them with the appropriate clamps to accommodate frame windings of different diameters.

[0085] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. 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.
