In addition, unless clearly defined in the text, terms such as those defined in a general dictionary should be interpreted as having a meaning consistent with their meaning in the relevant art and the content of this application, and will not be interpreted as idealized or overly formal meanings.

[0114] The following refers to the accompanying drawings to further describe in detail the specific implementation manners of this application.

[0115] Please refer to Figure 1 , the variable pitch optical fiber winding device 100 of this application includes a first traction device 10, a second traction device 20, a skeleton length detection device 70, a winding device 40, a wire feeding device 50 and a control device 5.

[0116] The first traction device 10 is for the skeleton 1 to pass through and is used to traction one end of the skeleton 1 to move. The second traction device 20 is also for the skeleton 1 to pass through and is arranged on one side of the first traction device 10 at an interval along the traction direction of the skeleton 1, and is used to traction the other end of the skeleton 1 to move. The first traction device 10 and the second traction device 20 jointly traction the skeleton 1 to move from one side of the first traction device 10 towards the other side of the second traction device 20, so that the skeleton 1 moves relative to the winding device 40, and thus the optical fiber is wound around different sections of the skeleton 1 through the winding device 40.

[0117] The skeleton length detection device 70 is arranged between the first traction device 10 and the second traction device 20 and is used to detect the moving distance of the skeleton 1 relative to the winding device 40.

[0118] The winding device 40 is arranged on the side of the skeleton length detection device 70 away from the first traction device 10 and can rotate around the skeleton 1. When the skeleton 1 passes through the winding device 40, the winding device 40 traction the optical fiber to rotate around the skeleton 1, and thus the optical fiber is gradually wound around different sections of the skeleton 1.

[0119] The pay-off device 50 is disposed at one side of the winding device 40 , and stores the optical fiber to be wound, and pulls one end of the optical fiber to be wound from the pay-off device 50 to the winding device 40 , thereby gradually pulling the optical fiber stored in the pay-off device 50 to the winding device 40 .

[0120] The control device 5 is a PLC controller, etc., which is respectively connected to the skeleton length detection device 70, the first traction device 10, the second traction device 20 and the winding device 40 by signals. The skeleton length detection device 70 continuously detects the moving distance of the skeleton 1 relative to the winding device 40, and feeds back the detection result to the control device 5 in real time. When the moving distance of the skeleton 1 reaches the preset value in the control device 5, the control device 5 adjusts the winding speed of the winding device 40 to change the pitch of the optical fiber wound on the skeleton 1, thereby realizing that different sections of the skeleton 1 are automatically wound with optical fibers of different pitches.

[0121] Please combine again Figures 1 to 3 In one embodiment, the variable pitch optical fiber winding device 100 further includes a front machine 2 and a rear machine 3, which are arranged at intervals along the pulling direction of the frame 1. The first pulling device 10 is installed at the top of the front machine 2, and the second pulling device 20 is installed at the top of the rear machine 3. The first pulling device 10 and the second pulling device 20 have the same structure and function. Only the structure and function of the first pulling device 10 are described below, and the second pulling device 20 is not repeated.

[0122] The first traction device 10 includes a first traction assembly 11, a second traction assembly 12 and a lifting assembly 13. The first traction assembly 11, the second traction assembly 12 and the lifting assembly 13 are all installed on the front machine 2. The first traction assembly 11 and the second traction assembly 12 are arranged at intervals and are arranged on the upper and lower sides of the skeleton 1. The lifting assembly 13 is connected to the first traction assembly 11 in a transmission manner and is used to drive the first traction assembly 11 to approach or move away from the second traction assembly 12. When the first traction device 10 needs to pull the skeleton 1 to move, the lifting assembly 13 drives the first traction assembly 11 to approach the second traction assembly 12, and the first traction assembly 11 moves to press the skeleton 1 against the second traction assembly 12, thereby driving the skeleton 1 to move after the first traction assembly 11 and the second traction assembly 12 clamp the skeleton 1. When the first traction device 10 stops pulling the skeleton 1, the lifting assembly 13 drives the first traction assembly 11 away from the second traction assembly 12, and the skeleton 1 is no longer clamped by the first traction assembly 11 and the second traction assembly 12 and stops moving.

[0123] The first traction assembly 11 includes a first traction frame 111, two first traction wheels 112 and a first traction belt 113. The two first traction wheels 112 are arranged at intervals along the traction direction of the skeleton 1. The two first traction wheels 112 have the same structure and size, and are both arranged in a columnar structure. The two first traction wheels 112 can be rotatably mounted on the first traction frame 111, and the first traction belt 113 is arranged around the outer periphery of the two first traction wheels 112. In this way, when the first traction belt 113 presses the skeleton 1 against the second traction assembly 12, the second traction assembly 12 drives the skeleton 1 to move. During the movement, the skeleton 1 is hindered by the first traction belt 113 and drives the first traction belt 113 to move, so that the first traction belt 113 rotates around the two first traction wheels 112, reducing the resistance of the skeleton 1 to the first traction belt 113 during the movement.

[0124] The second traction assembly 12 includes a traction drive 121, a second traction frame 122, two second traction wheels 123 and a second traction belt 124. The second traction frame 122 is installed at the top of the front machine 2 and is located on one side of the frame 1. The two second traction wheels 123 are arranged at intervals along the traction direction of the frame 1 on the side of the second traction frame 122 close to the frame 1, and are rotatably installed on the second traction frame 122.

The traction drive 121 is a device such as a motor, which is connected to a second traction wheel 123 in a transmission manner. The traction drive 121 is located on the side of the second traction frame 122 away from the frame 1, and is fixed to the top of the front machine 2. The traction drive 121 drives a second traction wheel 123 connected thereto to rotate. The second traction wheel 123 further drives the second traction belt 124 connected thereto to rotate, and the frame 1 is pressed against the second traction belt 124 by the first traction belt 113. When the second traction belt 124 rotates around the second traction wheel 123, the second traction belt 124 further drives the frame 1 to move.

[0125] The lifting assembly 13 includes a lifting drive 131 and a lifting plate 132. The lifting drive 131 is a device such as a cylinder, and is fixed to the side of the second traction frame 122 away from the frame 1. The lifting plate 132 is installed at the driving end of the lifting drive 131, and the lifting plate 132 is connected to the first traction frame 111. When the lifting drive 131 drives the lifting plate 132 to rise and fall, the lifting plate 132 further drives the first traction frame 111 connected thereto to rise and fall, so that the first traction belt 113 is away from or close to the second traction belt 124.

[0126] Specifically, the first traction assembly 11 further includes a plurality of first tension wheels 114, which are arranged at intervals along the traction direction of the framework 1. The plurality of first tension wheels 114 are all located between the two first traction wheels 112 and are rotatably connected to one side of the first traction frame 111 close to the framework 1. A part of the first traction belt 113 is tightly abutted against the plurality of first tension wheels 114 to ensure the tension of the first traction belt 113 and ensure that the first traction belt 113 can press the framework 1 tightly.

[0127] The second traction assembly 12 further includes a plurality of second tension wheels 125, which are arranged at intervals along the traction direction of the framework 1. The plurality of second tension wheels 125 are all located between the two second traction wheels 123 and are rotatably connected to one side of the second traction frame 122 close to the framework 1. A part of the second traction belt 124 is tightly abutted against the plurality of second tension wheels 125 to ensure the tension of the second traction belt 124 and ensure that the second traction belt 124 can traction the framework 1 to move.

[0128] Please further combine Figure 2 and Figure 3 In an embodiment, the first traction device 10 further includes a front guiding assembly 14 and a rear guiding assembly 15. Along the traction direction of the framework 1, the front guiding assembly 14 and the rear guiding assembly 15 are respectively arranged on the opposite sides of the second traction assembly 12. Among them, the front guiding assembly 14 includes a guiding plate 141 and two guiding wheels 142. The guiding plate 141 protrudes outward from one side of the second traction frame 122 close to the framework 1, and the two guiding wheels 142 are rotatably arranged at the top of the guiding plate 141 and are respectively located on both sides of the framework 1. The framework 1 passes through between the two guiding wheels 142 and is respectively tightly abutted against the two guiding wheels 142 to ensure that the traction direction of the framework 1 will not change.

[0129] Specifically, the structure and function of the rear guiding assembly 15 are the same as those of the front guiding assembly 14, and will not be described in detail.

[0130] Please further combine Figure 2 In an embodiment, the variable pitch optical fiber winding device 100 further includes a framework tension detection device 30. The framework tension detection device 30 includes a first sensor 32 and a framework tension detection wheel 31. The first sensor 32 is a tension detector, which is installed on the second traction frame 122. The first sensor 32 is located on the side of the rear guiding assembly 15 away from the front guiding assembly 14, and the framework tension detection wheel 31 is rotatably installed at the detection end of the first sensor 32. A part of the framework 1 abuts against the outer periphery of the framework tension detection wheel 31. During the movement of the framework 1, it always abuts against the outer periphery of the framework tension detection wheel 31. Furthermore, the first sensor 32 detects the tension magnitude of the framework 1 and transmits the detection result to the control device 5 which is signal-connected thereto.

[0131] Please further combine Figure 4, in one embodiment, the variable pitch optical fiber winding device 100 further includes a main platform 4 and a skeleton tension adjusting device 60. The main platform 4 is located between the front platform 2 and the rear platform 3, and the skeleton tension adjusting device 60 is installed at the top of the main platform 4.

[0132] The skeleton tension adjusting device 60 includes a skeleton tension adjusting bracket 61, a skeleton tension adjusting arm 62 that can swing relative to the skeleton tension adjusting bracket 61, a skeleton tension adjusting wheel 63 rotatably installed on the skeleton tension adjusting arm 62, a skeleton tension adjusting driving member 64, and a first angle sensor 65.

[0133] The skeleton tension adjusting bracket 61 is installed at the top of the main platform 4 and is located on one side of the skeleton. One end of the skeleton tension adjusting arm 62 is rotatably connected to the side of the skeleton tension adjusting bracket 61 close to the skeleton 1. The first angle sensor 65 is installed at the position where the skeleton tension adjusting arm 62 is rotatably connected to the skeleton tension adjusting bracket 61 to detect the swing angle of the skeleton tension adjusting arm 62. The first angle sensor 65 is signal-connected to the control device 5 to feedback the detected swing angle to the control device 5. The skeleton tension adjusting wheel 63 is rotatably installed at the other end of the skeleton tension adjusting arm 62. When the skeleton 1 is pulled through the skeleton tension adjusting device 60, the skeleton 1 abuts against the bottom of the skeleton tension adjusting wheel 63, and the skeleton tension adjusting wheel 63 applies a downward pressure to the skeleton 1, so as to maintain the tension of the skeleton 1 during the pulling process.

[0134] The skeleton tension adjusting driving member 64 is a cylinder and is located below the skeleton tension adjusting arm 62. The skeleton tension adjusting driving member 64 is installed on the skeleton tension adjusting bracket 61 and is inclined relative to the skeleton tension adjusting arm 62. The driving end of the skeleton tension adjusting driving member 64 is connected to the middle area of the skeleton tension adjusting arm 62 through a connecting rod 66, so as to drive the connecting rod 66 to extend or contract through the skeleton tension adjusting driving member 64, so that the skeleton tension adjusting arm 62 swings relative to the skeleton tension adjusting bracket 61, and then the skeleton tension adjusting arm 62 drives the skeleton tension adjusting wheel 63 to press against or away from the skeleton 1.

[0135] In this way, when the control device 5 receives the tension of the skeleton 1 detected by the first sensor 32 and finds that there is a deviation between the tension of the skeleton 1 and the preset value after comparison. The control device 5 controls the skeleton tension adjusting driving member 64 that is signal-connected to it to act, so that the skeleton tension adjusting arm 62 swings until the skeleton tension adjusting arm 62 swings to the required angle. The above required angle is the angle at which the skeleton tension adjusting arm 62 swings to make the force applied by the skeleton tension adjusting wheel 63 on the skeleton 1 make the tension of the skeleton 1 the preset value.

[0136] Please also combine with Figure 4, in one embodiment, the skeleton length detection device 70 includes a first detection bracket 71, a first detection wheel 72, and a first counting unit 73. The first detection bracket 71 is disposed between the first traction device 10 and the winding device 40. The first detection bracket 71 is located on one side of the skeleton tension adjustment bracket 61 and is fixed to the top of the main machine table 4. The first detection wheel 72 is rotatably mounted on the first detection bracket 71, and the first counting unit 73 is mounted on the skeleton tension adjustment bracket 61. A part of the skeleton 1 abuts against the outer peripheral surface of the first detection wheel 72. When the skeleton 1 is tractioned and moved, the skeleton 1 drives the first detection wheel 72 to rotate. The first counting unit 73 can be set as a wireless proximity switch or the like, and a marking member is attached to the outer periphery of the first detection wheel 72. When the marking member passes by the wireless proximity switch as the first detection wheel 72 rotates, the wireless proximity switch detects the number of times the marking member passes by, and thus detects the number of rotation cycles of the first detection wheel 72.

[0137] Specifically, the first counting unit 73 is signal-connected to the control device 5, transmits the number of rotation cycles of the first detection wheel 72 to the control device 5, and the control device 5 further obtains the moving distance of the skeleton 1 according to the number of rotation cycles of the first detection wheel 72 and the size of the first detection wheel 72.

[0138] Please refer to Figure 5 , in one embodiment, the variable pitch optical fiber winding device 100 further includes a sliding device 6.

[0139] Specifically, both the winding device 40 and the wire feeding device 50 are mounted on the sliding plate 602 to adjust the position of the winding device 40 relative to the skeleton 1, ensuring that the winding device 40 can start winding the optical fiber from a preset initial position of the skeleton 1.

[0140] Please refer to Figure 5 and Figure 6 , in one embodiment, the winding device 40 includes a winding driver 41 and a turntable 42. The winding driver 41 is a device such as a motor and is mounted on the sliding plate 602. The turntable 42 is for the skeleton 1 to pass through, and the winding driver 41 is drivingly connected to the turntable 42 for driving the turntable 42 to rotate around the skeleton 1.

The wire pay-off reel 51 is for winding the optical fiber thereon. When the wire pay-off reel 51 rotates, the wire pay-off reel 51 can gradually draw the optical fiber wound thereon to the winding device 40.

[0142] Please further combine Figure 5 and Figure 6 , in an embodiment, the variable pitch optical fiber winding device 100 further includes an optical fiber control device 80. The optical fiber control device 80 is fixed to the rotary disk 42 and can rotate around the skeleton 1 with the rotary disk 42.

[0143] The optical fiber control device 80 includes a mounting frame 81, an optical fiber length detection component 82, an optical fiber tension detection component 83, and an optical fiber tension adjustment component 84. The mounting frame 81 is fixed to one side of the rotary disk 42 close to the wire pay-off reel 51, and the optical fiber tension detection component 83, the optical fiber tension adjustment component 84, and the optical fiber length detection component 82 are all mounted on the mounting frame 81. The optical fiber passes through the optical fiber length detection component 82, the optical fiber tension detection component 83, and the optical fiber tension adjustment component 84 in sequence after being drawn out from the wire pay-off reel 51.

[0144] The optical fiber length detection component 82 is used for detecting the length of the optical fiber, and includes a second detection wheel 821 and a second counting unit 822. The second detection wheel 821 is rotatably mounted on the mounting frame 81, and the optical fiber winds around the second detection wheel 821. When the optical fiber is drawn and moved, the second detection wheel 821 rotates under the action of the optical fiber. The second counting unit 822 is a wireless proximity switch or the like. Like the first counting unit 73 above, it is used for detecting the number of rotations of the second detection wheel 821, and then transmitting the detected number of rotations to the control device 5 connected to it by signal. The control device 5 calculates the moving distance of the optical fiber according to the number of rotations of the second detection wheel 821 and the size of the second detection wheel 821, so as to obtain the length of the optical fiber that has been used in meters.

[0145] The optical fiber tension detection component 83 is used for detecting the tension magnitude when the optical fiber is drawn, and includes a second sensor 831 and an optical fiber tension detection wheel 832.

During the process of the optical fiber being drawn and moved, it always abuts against the outer circumference of the optical fiber tension detection wheel 832, and then the second sensor 831 detects the tension magnitude when the optical fiber is drawn, and transmits the detection result to the control device 5 connected to it by signal.

[0146] The optical fiber tension adjusting assembly 84 is used to adjust the tension of the optical fiber when it is being pulled, so that the optical fiber can be wound around the skeleton 1 more tightly.

[0147] One end of the optical fiber tension adjusting arm 841 is connected to the rotating shaft 842, and the rotating shaft 842 is rotatably connected to the mounting bracket 81. The second angle sensor 846 is mounted on the rotating shaft 842 to detect the swinging angle of the optical fiber tension adjusting arm 841. The second angle sensor 846 is signal-connected to the control device 5 to feed back the detected swinging angle to the control device 5. The optical fiber tension adjusting wheel 844 is rotatably mounted at the other end of the optical fiber tension adjusting arm 841. When the optical fiber is pulled through the optical fiber tension adjusting device, the optical fiber abuts against the bottom of the optical fiber tension adjusting wheel 844, and the optical fiber tension adjusting wheel 844 applies a downward pressure to the optical fiber, so as to maintain the tension of the optical fiber during the pulling process.

[0148] The optical fiber tension adjusting driving member 845 is a cylinder and is mounted on the mounting bracket 81. One end of the connecting rod 66 is rotatably connected to the driving end of the optical fiber tension adjusting driving member 845, and the other end is connected to the rotating shaft 842, so as to drive the intermediate rod 843 to swing through the optical fiber tension adjusting driving member 845, thereby driving the rotating shaft 842 to rotate by the intermediate rod 843, and further driving the optical fiber tension adjusting arm 841 to swing by the rotating shaft 842, and the optical fiber tension adjusting arm 841 drives the optical fiber tension adjusting wheel 844 to press the optical fiber or move away from the optical fiber.

[0149] Please also combine Figure 5 and Figure 6 In one embodiment, the variable pitch optical fiber winding device 100 further includes a pitch detection device 7. The pitch detection device 7 is arranged on one side of the winding device 40 close to the second traction device 20. The pitch detection device 7 is used to detect the pitch of the optical fiber wound around the skeleton 1, so as to stop the machine in time or adjust the working state of the variable pitch optical fiber winding device 100 when the pitch of the optical fiber does not meet the preset value. The pitch detection device 7 includes a fixing bracket 701 and a camera 702. The fixing bracket 701 is mounted on the sliding plate 602, and the camera 702 is mounted on the fixing bracket 701 and is located on one side of the skeleton 1 around which the optical fiber is wound, so as to take pictures of the optical fiber. The camera 702 is signal-connected to the control device 5 to upload the captured image to the control device 5, and the control device 5 identifies the pitch of the optical fiber wound on the skeleton 1 according to the image.

[0150] Please also combine Figure 1, in one embodiment, the variable pitch optical fiber winding device 100 further includes a cementing device 90, and the cementing device 90 is used to coat and cure an adhesive layer on the optical fiber wound around the skeleton 1. The cementing device 90 is disposed between the main machine table 4 and the rear machine table 3, and includes a glue coating mechanism 91 and a curing mechanism 92. The glue coating mechanism 91 and the curing mechanism 92 are sequentially arranged along the traction direction of the skeleton 1. The glue coating mechanism 91 is used to coat glue on the skeleton 1 around which the optical fiber is wound, so as to form an adhesive layer on its outer periphery. The curing mechanism 92 is used to heat the adhesive layer to cure it.

[0151] Please refer to Figure 7 , the embodiment of the present application further provides a variable pitch optical fiber winding method 200, and the variable pitch optical fiber winding method 200 is applied to the above-mentioned variable pitch optical fiber winding device 100, and includes the following steps:

[0152] S1. Pull out the skeleton 1 from the first traction device 10, and sequentially pull the skeleton 1 through the skeleton tension detection assembly, the skeleton tension adjustment assembly, the skeleton length detection device 70, the winding device 40, and pull out the skeleton 1 from the second traction device 20.

[0153] In this step, when pulling the skeleton 1 through the first traction device 10, first pass one end of the skeleton 1 through between the two guide wheels 142 of the front guide assembly 14, then pull the skeleton 1 through between the first traction belt 113 and the second traction belt 124, and then pass the skeleton 1 through the rear guide assembly 15.

[0154] After pulling one end of the skeleton 1 through the first traction device 10, sequentially pull the skeleton 1 through the skeleton tension detection wheel 31, the skeleton tension adjustment wheel 63, and the first detection wheel 72, and ensure that the skeleton 1 is in contact with the skeleton tension detection wheel 31, the skeleton tension adjustment wheel 63, and the first detection wheel 72.

[0155] Finally, pull the skeleton 1 through the rotary disk 42, the winding cylinder, the glue coating mechanism 91 and the curing mechanism 92 in sequence until one end of the skeleton 1 passes out of the second traction device 20.

[0156] S2. Segment the skeleton 1 in sequence along the traction direction of the skeleton to obtain a plurality of skeleton segments.

[0157] In this step, the skeleton 1 is divided into a plurality of skeleton segments, and a corresponding optical fiber winding pitch is set for each skeleton segment. Different pitch optical fibers can be wound on each skeleton segment to realize the preparation of variable pitch closely wound optical fibers.

[0158] Specifically, after the traction of the skeleton 1 is completed, the sliding driving member 601 is used to drive the sliding of the sliding plate 602, so that the winding device 40 slides along the traction direction of the skeleton 1, thereby adjusting the position of the winding device 40 relative to the skeleton 1, ensuring that the initial end of the first wound skeleton segment is located at the winding device 40, and completing the alignment of the skeleton 1 and the winding device 40.

[0159] S3. Store the standard meter length and standard pitch of the skeleton corresponding to multiple skeleton segments in the control device 5.

[0160] In this step, different skeleton segments can be set to different lengths or the same length. In the control device 5, the preset standard meter lengths and standard pitches of the respective skeletons corresponding to different skeleton segments are convenient for ensuring that the pitch of the optical fiber on the skeleton 1 is the same as the standard pitch corresponding to the current skeleton segment when winding optical fibers on different skeleton segments subsequently.

[0161] In this step, the control device 5 presets at least two standard meter lengths of the skeleton and at least two standard pitches. At least two standard pitches are respectively set corresponding to at least two standard meter lengths of the skeleton. The control device 5 compares the moving distance of the skeleton 1 with the standard meter length of the skeleton, so as to adjust the winding speed of the optical fiber after the moving distance of the skeleton 1 reaches the standard meter length of the skeleton, so that the pitch of the optical fiber wound on the skeleton 1 is the standard pitch corresponding to the standard meter length of the skeleton, thereby realizing the winding of optical fibers with different pitches on one skeleton 1.

[0162] S4. Start the variable pitch optical fiber winding device 100 and adjust the winding speed of the winding device 40 according to the standard pitch of the skeleton segment located at the front end along the traction direction of the skeleton 1.

[0163] In this step, after the alignment of the skeleton 1 and the winding device 40 is completed, one end of the optical fiber is pulled out from the unwinding bobbin 51, and the optical fiber is pulled through the second detection wheel 821, the optical fiber tension detection wheel 832, and the optical fiber tension adjustment wheel 844 in sequence, and the optical fiber is kept in contact with the second detection wheel 821, the optical fiber tension detection wheel 832, and the optical fiber tension adjustment wheel 844. Subsequently, the optical fiber is pulled and pre-wound to the front end of the first wound skeleton segment.

[0164] Before the variable pitch optical fiber winding device 100 is started, first adjust the winding speed of the winding device 40 according to the standard pitch of the first wound skeleton segment, and after the variable pitch optical fiber winding device 100 is started, the optical fiber starts to be wound on the skeleton 1 from the pre-wound position. When the skeleton 1 is pulled and moved, the optical fiber rotates around the skeleton 1 at a fixed position and is arranged on the skeleton 1 in a substantially spiral manner, and different winding speeds of the optical fiber will result in different pitches of the optical fiber on the skeleton 1.

[0165] It should be noted that the corresponding relationship between the standard pitch after fiber winding and the winding speed of the winding device 40 can be obtained by conducting multiple winding tests in advance.

[0166] S5. When the skeleton length detection device 70 detects that the moving distance of the skeleton 1 is consistent with the standard meter length of the skeleton, the control device 5 retrieves the standard pitch corresponding to the adjacent skeleton segment located behind the current skeleton segment, and adjusts the winding speed of the winding device 40 according to the standard pitch.

[0167] In this step, after the skeleton 1 is aligned with the winding device 40, when the control device 5 calculates from the signal transmitted by the first counting unit 73 that the moving distance of the skeleton 1 relative to the winding device 40 is the same as the standard meter length of the first wound skeleton segment, the control device 5 retrieves the standard meter length and the standard pitch corresponding to the adjacent skeleton segment located behind the current skeleton segment, and adjusts the winding speed of the winding device 40 according to the standard pitch, so that the pitch of the fiber wound on the current skeleton segment is the same as the standard pitch.

[0168] S6. Repeat step S5 until the fiber winding operation is completed for the skeleton segment located at the rear along the traction direction of the skeleton 1.

[0169] In this step, the skeleton segment located at the rear is the last skeleton segment to wind the fiber. After the fiber is wound on this skeleton segment, all the areas of the entire skeleton 1 that need to be wound with the fiber have been wound with the fiber, thus completing the entire winding operation.

[0170] In the above text, the specific embodiments of the present application have been described with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that various changes and substitutions can be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions all fall within the scope defined by the present application.
