Description

Technical Field

[0001] The present invention relates to the field of optical fiber guidance technology, and in particular to an optical fiber winding method and device for an optical fiber unmanned aerial vehicle. Background Art

[0002] At present, common optical fibers are usually wound layer by layer on an optical fiber reel, which has an inner outlet position of the optical fiber head and an outer outlet position of the optical fiber head. During the release process, the optical fiber is discharged from the outside, such as Figure 1 The fiber release process will pull the fiber reel to rotate. When the fiber reel is used on a drone, the rotating fiber reel may cause the fiber segment on the inside that is connected to the drone to rotate, which may damage or even break the fiber.

[0003] After searching, it was found that the patent with application number 202410433736.1 discloses a high-precision optical fiber winding auxiliary fiber arrangement device, including: a mounting frame, a rotating rod 1 is rotatably installed on the mounting frame, a motor 1 is installed on one side of the mounting frame, the output shaft of the motor 1 is fixedly connected to one end of the rotating rod 1, a circular baffle 1 is fixedly sleeved on the rotating rod 1, a mounting rod is installed on the top of the mounting frame, a rotating plate is rotatably installed on the mounting rod, a circular baffle 2 is rotatably installed on the rotating plate, a circular hole is opened on the circular baffle 2, a fixed block is installed on the mounting frame, an electric push rod 1 is rotatably installed on the fixed block, and a transfer block is fixedly installed on the output rod of the electric push rod 1. The optical fiber roll finally wound by this prior art is still an outgoing line structure, which only adopts a more efficient winding method, and still does not solve the problem of optical fiber damage or even breakage existing in optical fiber drones.

[0004] Patent application number 202410278938.3 discloses an optical fiber winding device and a fiber splitter, including a connecting shaft and a winding mechanism, the winding mechanism is connected to one end of the connecting shaft by transmission, and includes a plurality of fiber winding columns arranged in a circular array, the plurality of fiber winding columns can rotate around the axis of the connecting shaft and rotate simultaneously with the rotation of the connecting shaft, so that the optical fiber is wound on the outside of the plurality of fiber winding columns, and the distance between the plurality of fiber winding columns can be reduced or expanded as the connecting shaft moves along its own axis. The optical fiber can be wound on the optical fiber winding device, and the optical fiber winding device facilitates the rapid removal of the optical fiber after winding. The optical fiber winding method is still an outgoing method, and the optical fiber is fixed by winding the optical fiber on a cylindrical core. In this method, when the optical fiber is winding out, the optical fiber winding out is entangled, knotted, and stuck in the gap of the outer shell of the optical fiber roll when the drone is maneuvering, causing the optical fiber to be pulled; and the optical fiber roll must be placed horizontally, otherwise the optical fiber will be scattered.

[0035] An optical fiber winding method for an optical fiber drone provided by an embodiment of the present invention comprises the following steps:

[0036] S1. Adhesive attachment: attaching the adhesive to the surface of the optical fiber;

[0037] S2, winding the optical fiber into a roll: providing a thin plate-like material that can be bent into a roll, winding the thin plate-like material around a roller and fixing it on the roller, and then winding the optical fiber around the thin plate-like material;

[0038] S3. Fiber optic roll forming: After the adhesive is completely bonded, pull out the thin sheet material to obtain a fiber optic roll for a fiber optic drone, with the fiber optic roll coming out from the inside.

[0039] By adopting the optical fiber winding method in the embodiment of the present invention, an optical fiber reel led out from the inner side of the optical fiber head is obtained, and the optical fiber reel can be placed on the drone in any posture. No matter what kind of maneuver the drone makes, the optical fiber reel will not rotate during the line-laying process, and will not cause the optical fiber to become knotted, entangled, or stuck in the gap, and will not damage the optical fiber, thus solving the problem of rotational damage or even breakage of the optical fiber segment connected to the drone.

[0040] In step S1, an adhesive is first attached to the surface of the optical fiber to increase the stickiness between the optical fibers. In some embodiments, attaching the adhesive to the surface of the optical fiber includes: providing a filling box filled with adhesive, and the optical fiber passes through the filling box filled with adhesive, that is, the optical fiber is inserted from one end of the filling box and exits from the other end, thereby attaching the adhesive to the surface of the optical fiber.

[0041] The optical fiber roll is self-supporting due to the viscosity of the adhesive and will not fall apart. Before being added to the filling box, the adhesive should be in a liquid state. After the optical fiber winding is completed, it can be cured by drying, natural drying, etc. After the adhesive is cured, the optical fiber can still be pulled out from the optical fiber roll without affecting the output. In some embodiments, the adhesive is liquid glue or paraffin. In some other embodiments, other adhesives with bonding effects can also be used as long as they can achieve the same function as mentioned above.

[0042] In some embodiments, in step S2, the thin plate-like material is a masking paper or a plastic sheet, which can be bent into a roll, has good toughness, does not break when bent into a roll, has a certain strength after being rolled, has low surface friction, and is easy to remove from the roller for subsequent winding of the optical fiber.

[0043] In some embodiments, the rolled sheet-like material is fixed on the roller with an adhesive tape, and the sheet-like material is fixed by bonding, which ensures a firm connection and facilitates removal from the roller in subsequent steps.

[0044] In some embodiments, the optical fiber forms a spindle-shaped hollow cylinder on the thin plate-shaped material after winding. When the optical fiber is wound on the roller, due to gravity, the optical fiber wound later at the edge of the optical fiber roll will fall to the lower layer and entangle with the optical fiber wound earlier. Such a situation may cause the optical fiber to be knotted when it is output. To avoid this situation, during the optical fiber winding process, the length of the optical fiber roll is gradually lengthened to form a spindle shape, thereby preventing the optical fiber wound later from being entangled with the optical fiber wound earlier.

[0045] In some other embodiments, the optical fiber can also be formed into a cylindrical shape on the rolled thin plate material, but baffles need to be added at both ends during the optical fiber winding process to prevent the optical fiber from falling due to gravity and causing the optical fiber to become entangled during the winding process.

[0046] In the above embodiment of the present invention, the optical fiber winding method includes the steps of adhesive attachment, optical fiber winding into a roll, and optical fiber roll forming in sequence. When the optical fiber passes through the adhesive attachment step, a sticky adhesive will be attached to its surface. Due to the stickiness of the adhesive between the optical fibers, the optical fiber will remain in a roll shape after being rolled. When the optical fiber winding is completed, the optical fiber roll needs to be removed, and the adhesive needs to be dried and completely bonded. The optical fiber roll has a certain hardness, that is, after the thin plate-like material is pulled out of the optical fiber roll, the optical fiber does not fall apart when it is shaken, and the optical fiber can be adhered to the optical fiber roll, and it does not deform even when slightly squeezed. After the thin plate-like material such as masking tape / plastic sheet is pulled out, an optical fiber roll with the line coming out from the inside of the optical fiber can be obtained.

[0047] Based on the same inventive concept, another embodiment of the present invention provides an optical fiber winding device for an optical fiber drone, which is used to implement the optical fiber winding method for an optical fiber drone, referring to Figure 2-Figure 4 The device comprises: a frame 1, a transmission belt 2, a slider 3, a filling box 4 and a rotating shaft 5, etc. The frame 1 is used as the skeleton of the device to provide a stable installation foundation and a supporting structure for the device; the transmission belt 2 is arranged along the width direction of the frame 1, and both ends of the transmission belt 2 are connected to the frame 1, and one end of the transmission belt 2 is connected to the first motor 6, and the first motor 6 drives the transmission belt 2 to reciprocate by changing direction; the slider 3 is fixed on the transmission belt 2; the filling box 4 is fixed on the slider 3, and the filling box 4 is filled with adhesive, and the unwound optical fiber roll 10 (traditional optical fiber The reel) is fixed on the top of the frame 1, and the optical fiber is led out from the unwound optical fiber reel 10. The optical fiber passes through the top of the filling box 4 and passes through the bottom of the filling box 4, and the adhesive is attached to the surface of the optical fiber. The filling box 4 drives the optical fiber to reciprocate together; the rotating shaft 5 is arranged along the width direction of the frame 1, and the rotating shaft 5 is located below the transmission belt 2. The rotating shaft 5 is provided with a roller 9, and the roller 9 is fixed with a thin plate-like material rolled around the roller 9. The optical fiber passing through the bottom of the filling box 4 is fixed on the rolled thin plate-like material; one end of the rotating shaft 5 is connected to the second motor 7, such as Figure 2As shown, one end of the rotating shaft 5 is fixed on the second motor 7 and is driven to rotate by the second motor 7, and the other end is not fixed and is placed on the frame 1. When the formed optical fiber needs to be removed, the frame 1 can be removed, and the second motor 7 drives the roller 9 to rotate in one direction, pulling the optical fiber passing through the bottom of the filling box 4 and winding the optical fiber around the rolled thin plate material.

[0048] Exemplarily, the frame 1 includes a crossbeam at the top and a support structure located below the crossbeam, and the support structure is located at both ends of the crossbeam; the transmission belt 2 and both ends of the rotating shaft 5 are respectively connected to the support structures at both ends of the frame 1, and the unwound optical fiber roll 10 is located at the top of the frame 1, such as Figure 2 As shown, a fixing rod is provided below the crossbeam, and an unwound optical fiber reel 10 is fixed on the fixing rod. The optical fiber led out from the unwound optical fiber reel 10 is inserted into the top of the filling box 4, and after winding, an optical fiber reel is formed that leads out from the inner side of the optical fiber.

[0049] In some embodiments, an inlet ring 41 is provided at one end of the filling box 4, and an outlet ring 42 is provided at the other end. After the filling box 4 is installed on the frame 1, the inlet ring 41 faces the unwound optical fiber roll 10, and the outlet ring 42 faces the rotating shaft 5. The optical fiber enters the filling box 4 from the inlet ring 41 and leaves the filling box 4 from the outlet ring 42.

[0050] like Figure 3 As shown, the filling box 4 includes a box body and a cover body. Three pulleys are arranged inside the box body of the filling box 4, which are a first pulley 43, a second pulley 44 and a third pulley 45 arranged in sequence from the optical fiber input end of the filling box 4. The first pulley 43 is parallel to the third pulley 45, and the adhesive does not cover the second pulley 44. In the height direction of the filling box 4, the positions of the first pulley 43 and the third pulley 45 are higher than the second pulley 44. Specifically, the upper parts of the first pulley 43 and the third pulley 45 protrude from the top of the filling box 4, and the second pulley 43 and the third pulley 45 protrude from the top of the filling box 4. The wheel 44 is flush with the height of the box body, the upper parts of the first pulley 43 and the third pulley 45 are above the adhesive liquid surface, and the lower parts are submerged below the liquid surface; the second pulley 44 is completely submerged below the adhesive liquid surface, and the optical fiber enters the filling box 4 from the input end ring 41, passes through the first pulley 43 from the side close to the cover body, and then passes through the second pulley 44 from the side close to the bottom of the box body and is immersed in the adhesive, and then passes through the third pulley 45 from the side close to the cover body, and finally leaves the filling box 4 from the output end ring 42 to complete the adhesive attachment.

[0051] In some embodiments, a swing rod 8 is provided on the slider 3, and the optical fiber led out from the filling box 4 passes through the swing rod 8. The swing rod 8 is used to continue pulling the optical fiber by swinging itself when the first motor 6 changes direction and stops, so as to maintain the reciprocating movement state of the optical fiber.

[0052] Specifically, the optical fiber drawn from the filling box 4 passes through the swing rod 8, is rolled with a thin plate-like material around the roller 9, and is fixed to the roller 9 with an adhesive tape, and then one end of the optical fiber is fixed to the thin plate-like material. For example, one end of the optical fiber is adhered to the thin plate-like material by the adhesive tape; then the first motor 6 and the second motor 7 are started, and the second motor 7 always drives the roller 9 to rotate in one direction. During the rotation of the roller 9, the optical fiber will be pulled and wound around the rolled thin plate-like material; the first motor 6 will drive the transmission belt 2 to reciprocate by changing direction, and the slider 3 is fixed on the transmission belt 2 to reciprocate together. The filling box 4 and the swing rod 8 are both fixed on the slider 3, and reciprocate with the slider 3. This process will drive the optical fiber to reciprocate together, so that the optical fiber reciprocates back and forth when it is wound on the thin plate-like material on the fixed roller 9. Since the first motor 6 needs to pause when turning, when the first motor 6 pauses, the swing rod 8 rotates to enable the optical fiber to continuously reciprocate during winding. When the step of winding the optical fiber into a roll is completed, the optical fiber will form a spindle-shaped hollow cylinder on the rolled thin plate-like material on the roller 9.

[0053] Continue to refer to Figure 2-Figure 4 The specific process of performing optical fiber winding using the optical fiber winding device for optical fiber drone in the above embodiment of the present invention is as follows:

[0054] The unwound fiber roll 10 is fixed on the top of the frame 1, and the thin plate-like material such as masking paper / plastic sheet is rolled and fixed along the roller 9, and then the optical fiber is led out from the traditional optical fiber roll, passed through the filling box 4 and the swing rod 8, and fixed to one end of the thin plate-like material that has been rolled. Add adhesive, such as liquid glue, paraffin, etc., to the filling box 4 so that the optical fiber is soaked with the adhesive. Then start the first motor 6 and the second motor 7, and the second motor 7 drives the roller 9 to rotate, and then the roller 9 pulls the optical fiber to continuously circle around the thin plate-like material. The first motor 6 continuously changes direction, so that the slider 3 fixed on the transmission belt 2 drives the filling box 4 and the swing rod 8 to reciprocate together, and at the same time, the swing rod 8 swings to maintain the reciprocating state of the optical fiber when the first motor 6 changes direction and stops. In this way, the optical fiber will be wound into a spindle-shaped hollow cylindrical roll on the thin plate-like material.

[0055] In the above-mentioned embodiment of the present invention, the adhesive is first attached to the surface of the optical fiber, and then the optical fiber is wound on the rolled thin plate-like material. When the adhesive is completely bonded and the optical fiber roll has a certain hardness, the thin plate-like material is pulled out to obtain an optical fiber roll for an optical fiber drone. When the wound optical fiber roll is output, the optical fiber head is led out from the inside, and no rotation occurs during the pay-off process, which solves the problem that when the optical fiber roll is placed on the drone, the optical fiber is easily damaged or even broken due to the output from the outside.

[0056] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention. The above preferred features can be used in any combination without conflicting with each other.
