Description

Technical Field

[0001] This invention relates to the field of optical fiber manufacturing technology, specifically to an anti-whiplash device and method for high-speed optical fiber switching. Background Technology

[0002] In current optical fiber production processes, when switching between the two ends of the take-up machine, the fiber tip may strike the substrate surface of the large fiber reel, causing fiber breakage during fiber sorting. This not only easily produces defective products but also reduces the reel fill rate, affecting operators' judgment of fiber sorting status and resulting in cost losses. Therefore, anti-whiplash switching devices are currently used to reduce whiplash. However, existing anti-whiplash switching devices have certain shortcomings; their design only reduces whiplash and cannot completely guarantee its prevention, nor can they meet the requirements for high-speed fiber switching that may cause whiplash. Therefore, these problems urgently need to be solved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a high-speed fiber optic switching anti-whipping device and method. By using the main electromagnetic component and the auxiliary electromagnetic component in combination, the fiber optic head cannot hit the large disk, thus fundamentally solving the fiber whipping problem, thereby ensuring the normal operation of production and ensuring the quality of the fiber.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The innovative feature of the fiber optic high-speed switching anti-whiplash device of the present invention is that it includes a moving mechanism I, a cable guide wheel group, a left take-up mechanism, a pressure wheel, a drive mechanism I, and a right take-up mechanism; the left and right take-up mechanisms are arranged horizontally and longitudinally at intervals, and each rotates around its own axis, ensuring that their rotation directions are opposite; a pressure wheel is also arranged vertically and laterally between the left and right take-up mechanisms, and the pressure wheel is arranged without interfering with the left and right take-up mechanisms, and moves horizontally and vertically through the drive mechanism I; a cable guide wheel group is also arranged directly above the left take-up mechanism, and the cable guide wheel group moves horizontally and longitudinally in the area above the left take-up mechanism through the moving mechanism I, thereby performing take-up operations for either the left or right take-up mechanism through the horizontal longitudinal movement of the cable guide wheel group, and switching between the left and right take-up mechanisms through the horizontal lateral movement of the cable guide wheel group and the assistance of the pressure wheel; It also includes a fixed frame; the fixed frame is a rectangular structure arranged vertically and horizontally, and the fixed end of the moving mechanism I is vertically fixedly connected to the front surface of the fixed frame near its top position. The left take-up mechanism and the right take-up mechanism are symmetrically arranged on the front side of the fixed frame at intervals, relative to the cable guide wheel assembly below, and it is necessary to ensure that the left take-up mechanism and the right take-up mechanism do not interfere with the cable laying action of the cable guide wheel assembly. The left and right take-up mechanisms have the same structure. The left take-up mechanism includes a driven shaft, a fixed plate, a main electromagnetic assembly, a secondary electromagnetic assembly, a large disc, a large disc fixing mechanism, a drive shaft, a moving mechanism II, and a servo motor. A driven shaft is also horizontally and longitudinally positioned on the left side of the front surface of the fixed frame. The rear end of the driven shaft is rotatably connected to the front surface of the fixed frame around its own axis. A circular fixed plate is coaxially fitted and fixed at the middle position of the driven shaft, and a main electromagnetic assembly is coaxially fitted and fixed on the main electromagnetic assembly relative to the front side of the fixed plate. The front end of the main electromagnetic assembly is the electromagnetic end, and its rear end is the fixed end, which is coaxially fixedly connected to the front surface of the fixed plate, and thus follows the driven shaft.

The outer diameter of the secondary electromagnetic assembly is the same as that of the main electromagnetic assembly. The rear end of the secondary electromagnetic assembly is the electromagnetic end, and its front end is the fixed end. It is fixedly connected to the end of each spring away from the positioning plate, so that it rotates synchronously with the driven shaft. Under the action of the main electromagnetic assembly, the secondary electromagnetic assembly slides horizontally along the length of the driven shaft to reduce the gap between the main electromagnetic assembly and the secondary electromagnetic assembly. A drive shaft is horizontally and longitudinally arranged on the front side of the driven shaft, and the drive shaft and the driven shaft are coaxially arranged with a front-to-back gap; the drive shaft is mounted on the moving end of the moving mechanism II via bracket I, and the drive shaft is rotatably connected to bracket I via bearings around its own axis, and performs horizontal longitudinal reciprocating motion in the area in front of the driven shaft via the moving mechanism II, thereby adjusting the distance between the drive shaft and the driven shaft; the front end of the drive shaft vertically penetrates the front surface of bracket I and is linked to the drive end of the servo motor, so that the drive shaft rotates around its own axis under the drive of the servo motor; A large disk fixing mechanism is coaxially and fixedly mounted on the drive shaft relative to the rear side of bracket I.

Furthermore, a positioning hole matching the positioning block is vertically embedded on the rear end face of the large disk relative to the position of each positioning block. Thus, the stability of the connection between the large disk and the secondary electromagnetic component is ensured through the snap-fit ​​cooperation between the positioning block and the positioning hole.

[0007] Preferably, the assembly further includes clamping plate I, clamping plate II, and cutter head I. A circular clamping plate I is coaxially fixed to the front end face of the main electromagnetic assembly. The outer diameter of clamping plate I is smaller than the outer diameter of the main electromagnetic assembly, and it is coaxially spaced and sleeved on the driven shaft, without affecting the magnetic attraction between the main and auxiliary electromagnetic assemblies.

A cutter head I is also provided on the inner circumferential surface of clamping plate II. When the coil winding is completed, the auxiliary electromagnetic assembly moves horizontally towards the main electromagnetic assembly through the action of the main electromagnetic assembly. Then, through the cooperation of clamping plate I and clamping plate II, the optical fiber wound on the main and auxiliary electromagnetic assemblies is clamped, and the optical fiber is cut by the cutter head I.

[0008] Preferably, it further includes a clamping block, a cutter head II, a bracket II, and a moving mechanism III; a clamping block is coaxially sleeved on the driven shaft relative to the fixed frame and the fixed plate, the clamping block has a U-shaped cross-section, and its inner diameter matches the diameter of the fixed plate, ensuring that its open end faces the fixed plate; the clamping block is mounted on the upper end of the bracket II via a bearing seat, and the lower end of the bracket II is fixedly mounted on the moving end of the moving mechanism III, and performs horizontal longitudinal reciprocating motion in the area between the fixed frame and the fixed plate through the moving mechanism III; the clamping block and the bearing seat rotate around their own axial direction, and a miniature cylinder is horizontally longitudinally arranged on its inner circumference near its rear inner side, the telescopic end of the miniature cylinder is horizontally longitudinally forward and connected to the cutter head II, and then, driven by the moving mechanism III, the optical fiber wound on the main electromagnetic assembly is clamped by the cooperation of the clamping block and the fixed plate, and then the optical fiber is cut by the cutter head II when the optical fiber is switched to the right take-up mechanism.

[0009] Preferably, the internal depth of the clamping block is greater than the thickness of the fixing plate, and it must be ensured that when the optical fiber is clamped by the clamping block and the fixing plate, the fixing plate does not interfere with the extension and retraction of the micro cylinder; the retraction limit position of the micro cylinder must be ensured that when the optical fiber is clamped by the clamping block and the fixing plate, the cutter head II will not cut the optical fiber; the extension limit position of the micro cylinder must be ensured that when the optical fiber is clamped by the clamping block and the fixing plate, the cutter head II can cut the optical fiber.

[0010] Preferably, it further includes a left auxiliary wheel, a drive mechanism II, a right auxiliary wheel, and a drive mechanism III; a left auxiliary wheel is also vertically and horizontally arranged between the left take-up mechanism and the pressure roller, and the left auxiliary wheel is configured to not interfere with the left take-up mechanism and the pressure roller respectively, and moves horizontally and longitudinally through the drive mechanism II; the fixed end of the drive mechanism II is fixedly arranged at the corresponding position on the front surface of the fixed frame, and its extension limit position must ensure that the left auxiliary wheel can extend to the position relative to the fixed plate, thereby assisting the take-up switching between the left and right take-up mechanisms through the left auxiliary wheel; a right auxiliary wheel is also vertically and horizontally arranged between the right take-up mechanism and the pressure roller, and... The right auxiliary wheel is configured to operate independently of the right take-up mechanism and the pressure wheel, and moves horizontally and longitudinally via drive mechanism III. The fixed end of drive mechanism III is fixedly positioned on the front surface of the fixed frame, and its extension limit position must ensure that the right auxiliary wheel can extend to a position relative to the fixed plate, thereby assisting the take-up switching between the left and right take-up mechanisms. The extension limit position of drive mechanism I must ensure that the pressure wheel can extend to a position relative to the fixed plate, and its descent limit position must ensure that the pressure wheel is located below the main electromagnetic assembly, thereby assisting the take-up switching between the left and right take-up mechanisms.

[0011] The present invention discloses an anti-whiplash method for a high-speed fiber optic switching anti-whiplash device, the innovation of which lies in including the following steps: Step 1: First, install the large disc coaxially on the large disc fixing mechanism of the left take-up mechanism. Then, driven by the moving mechanism II, the large disc moves horizontally and longitudinally with the drive shaft and is locked in place with the auxiliary electromagnetic component, thus completing the assembly of the left take-up mechanism. Step 2: Then, driven by the servo motor of the left take-up mechanism, the corresponding large disk, main electromagnetic component and auxiliary electromagnetic component rotate with the drive shaft; then, driven by the moving mechanism I, the fiber is laid out through the wire guide wheel group and the fiber is taken up onto the large disk of the left take-up mechanism; at the same time, the next large disk is installed on the right take-up mechanism and is in standby state. Step 3: After the large reel on the left take-up mechanism finishes taking up the fiber, the optical fiber is wound onto the auxiliary electromagnetic component via winding groove I, and then onto the main electromagnetic component via winding groove II. At this time, through the action of the main electromagnetic component, the auxiliary electromagnetic component moves horizontally towards the main electromagnetic component. Then, through the cooperation of clamping plates I and II, the optical fiber wound onto the main electromagnetic component and the auxiliary electromagnetic component is clamped, and then the optical fiber is cut by the cutter head I. At the same time, under the drive of the servo motor of the right take-up mechanism, the large reel, the main electromagnetic component and the auxiliary electromagnetic component rotate in opposite directions. Step 4: Then the optical fiber continues to be wound around the main electromagnetic component. At this time, under the drive of the moving mechanism III, the optical fiber wound around the main electromagnetic component is clamped by the cooperation of the clamping block and the fixed plate. Step 5: Then, driven by the moving mechanism I, the cable guide wheel assembly moves horizontally to directly above the right take-up mechanism. With the assistance of the pressure wheel, the left auxiliary wheel, and the right auxiliary wheel, the optical fiber is placed on the large tray of the right take-up mechanism. At the same time, driven by the micro cylinder, the cutter head II cuts the optical fiber on the main electromagnetic component. At this time, the optical fiber begins to be taken up onto the large tray of the right take-up mechanism under the cable guide wheel assembly, thus completing the take-up switch between the left and right take-up mechanisms. At this point, the large tray on the left take-up mechanism can be disassembled and replaced.

[0012] The beneficial effects of this invention are: (1) By using the main electromagnetic component and the auxiliary electromagnetic component together, the present invention ensures that the fiber head does not hit the large disk, thus fundamentally solving the problem of fiber whipping, thereby ensuring the normal operation of production and ensuring the quality of the fiber. (2) The present invention facilitates the switching between the left take-up mechanism and the right take-up mechanism when the optical fiber is at high speed by using the moving mechanism III, the clamping block, the cutter head II and the pressure roller in cooperation, thereby ensuring the normal operation of production; (3) The present invention ensures the stability of the switching process by using the left auxiliary wheel and the right auxiliary wheel in combination.

Detailed Implementation

[0017] The technical solution of the present invention will be clearly and completely described below through specific embodiments.

[0018] The present invention provides a fiber optic high-speed switching anti-whiplash device, comprising a moving mechanism I2, a cable guide wheel group 1, a left-side cable take-up mechanism 4, a pressure wheel 6, a driving mechanism I, and a right-side cable take-up mechanism 8; the specific structure is as follows: Figures 1-3As shown, the left take-up mechanism 4 and the right take-up mechanism 8 are arranged horizontally and longitudinally at intervals, and they rotate around their own axes, ensuring that their rotation directions are opposite. A pressure roller 6 is also arranged vertically and horizontally between the left take-up mechanism 4 and the right take-up mechanism 8. The pressure roller 6 is arranged without interfering with the left take-up mechanism 4 and the right take-up mechanism 8, and moves horizontally and vertically through the drive mechanism I (not shown in the figure). A wire guide roller group 1 is also arranged directly above the left take-up mechanism 4. The wire guide roller group 1 moves horizontally and horizontally in the area above the left take-up mechanism 4 through the moving mechanism I2. The wire take-up operation of the left take-up mechanism 4 or the right take-up mechanism 8 is performed by the horizontal movement of the wire guide roller group 1, and the wire take-up switching between the left take-up mechanism 4 and the right take-up mechanism 8 is performed by the horizontal movement of the wire guide roller group 1 and the assistance of the pressure roller 6.

[0019] like Figures 1-3 As shown, the fixed frame 401 is a rectangular structure arranged vertically and horizontally. The fixed end of the moving mechanism I2 is vertically and fixedly connected to the front surface of the fixed frame 401 near its top. The left take-up mechanism 4 and the right take-up mechanism 8 are symmetrically arranged at intervals on the front side of the fixed frame 401, below the cable guide wheel assembly 1. It is necessary to ensure that the left take-up mechanism 4 and the right take-up mechanism 8 do not interfere with the cable laying action of the cable guide wheel assembly 1. The moving mechanism I2 of this invention is a conventional structure that can drive the cable guide wheel assembly 1 to move horizontally. For example, it can combine two sets of screw and nut structures to achieve compound movement of the X-axis and Y-axis. This is prior art, so its specific structure will not be described in detail here.

[0020] The left take-up mechanism 4 and the right take-up mechanism 8 of this invention have the same structure, and the left take-up mechanism 4 includes a driven shaft 402, a fixed plate 403, a main electromagnetic assembly 404, a secondary electromagnetic assembly 405, a large disc 410, a large disc fixing mechanism 411, a drive shaft 412, a servo motor 413, clamping plate I, clamping plate II, a cutter head I 406, a clamping block 416, a cutter head II 417, a bracket II 418, a moving mechanism III 419, a left auxiliary wheel 5, a drive mechanism II, a right auxiliary wheel 7, and a drive mechanism III; as shown Figures 1-3As shown, a driven shaft 402 is horizontally and longitudinally arranged on the left side of the middle position of the front surface of the fixed frame 401. The rear end of the driven shaft 402 is rotatably connected to the front surface of the fixed frame 401 around its own axis. A circular fixed plate 403 is coaxially sleeved and fixed at the middle position of the driven shaft 402. A main electromagnetic assembly 404 is coaxially sleeved and fixed on the driven shaft 402 relative to the front side of the fixed plate 403. The front end of the main electromagnetic assembly 404 is the electromagnetic end, and its rear end is the fixed end. It is coaxially fixedly connected to the front surface of the fixed plate 403 and rotates synchronously with the driven shaft 402. A circular positioning plate is coaxially sleeved and fixed on the driven shaft 402 relative to the front side of the main electromagnetic assembly 404. Several springs are evenly distributed and vertically spaced along the circumference of the rear surface of the positioning plate. A secondary electromagnetic component 405 is coaxially sleeved between the main electromagnetic component 404 and the spring, and the outer diameter of the secondary electromagnetic component 405 is the same as that of the main electromagnetic component 404. The rear end of the secondary electromagnetic component 405 is the electromagnetic end, and its front end is the fixed end, which is fixedly connected to the end of each spring away from the positioning plate. It then rotates synchronously with the driven shaft 402. Under the action of the main electromagnetic component 404, the secondary electromagnetic component 405 slides horizontally along the length direction of the driven shaft 402 to reduce the gap between the main electromagnetic component 404 and the secondary electromagnetic component 405. The gap between the secondary electromagnetic component 405 and the driven shaft 402 in this invention must ensure that the secondary electromagnetic component 405 can rotate stably with the driven shaft 402 and that the driven shaft 402 does not interfere with the horizontal longitudinal movement of the secondary electromagnetic component 405. like Figures 1-3 As shown, a drive shaft 412 is horizontally and longitudinally arranged on the front side of the driven shaft 402, and the drive shaft 412 and the driven shaft 402 are coaxially arranged with a front-to-back gap. The drive shaft 412 is mounted on the moving end of the moving mechanism II 415 through the bracket I 414, and the drive shaft 412 is rotatably connected to the bracket I 414 around its own axis through the bearing, and performs horizontal longitudinal reciprocating motion in the area in front of the driven shaft 402 through the moving mechanism II 415, thereby adjusting the distance between the drive shaft 412 and the driven shaft 402. The front end of the drive shaft 412 vertically penetrates the front surface of the bracket I 414 and is linked to the drive end of the servo motor 413, so that the drive shaft 412 rotates around its own axis under the drive of the servo motor 413. The moving mechanism II 415 of the present invention is a conventional structure that can drive the bracket I 414 to move horizontally, such as a screw and nut structure, which is the prior art, so its specific structure will not be described in detail here.

[0021] like Figures 1-3As shown, a large disk fixing mechanism 411 is coaxially and fixedly mounted on the active shaft 412 relative to the rear side of the bracket I 414. The large disk 410 is coaxially and spacedly mounted on the active shaft 412 relative to the rear side of the large disk fixing mechanism 411 and is fixed by the large disk fixing mechanism 411. The rear end of the large disk 410 extends vertically out of the vertical plane where the rear end of the active shaft 412 is located, and moves horizontally and longitudinally with the active shaft 412. The rear end of the large disk 410 is coaxially engaged with the front end of the auxiliary electromagnetic component 405. Then, under the drive of the servo motor 413, the driven shaft 402 rotates synchronously with the active shaft 412. Then, through the cable guide wheel group 1, the optical fiber 3 is wound onto the large disk 410.

[0022] like Figures 1-3 As shown, the diameter of the positioning plate is smaller than the outer diameter of the secondary electromagnetic component 405. Several positioning blocks 409 are evenly distributed along the circumference of the front end face of the secondary electromagnetic component 405 relative to the outer side of the positioning plate. Positioning holes matching the positioning blocks 409 are also vertically embedded on the rear end face of the large disk 410 relative to the position of each positioning block 409. The stability of the connection between the large disk 410 and the secondary electromagnetic component 405 is ensured by the snap-fit ​​cooperation between the positioning blocks 409 and the positioning holes.

[0023] like Figures 1-3 As shown, a spiral groove II 408 matching the optical fiber 3 is coaxially embedded in the outer circumference of the main electromagnetic component 404, and the spiral groove II 408 does not affect the magnetic attraction between the main electromagnetic component 404 and the auxiliary electromagnetic component 405; a spiral groove I 407 matching the optical fiber 3 is coaxially embedded in the outer circumference of the auxiliary electromagnetic component 405, and the spiral groove I 407 does not affect the magnetic attraction between the main electromagnetic component 404 and the auxiliary electromagnetic component 405; the opening direction of the spiral groove I 407 is consistent with the opening direction of the spiral groove II 408, and its opening direction must ensure that when the large coil 410 finishes winding, the optical fiber 3 is wound around the auxiliary electromagnetic component 405 with the spiral groove I 407, and then wound around the main electromagnetic component 404 with the spiral groove II 408.

[0024] In this invention, a circular clamping plate I is coaxially fixed to the front end face of the main electromagnetic assembly 404, such as... Figures 1-3As shown, the outer diameter of clamping plate I is smaller than the outer diameter of the main electromagnetic assembly 404, and it is coaxially spaced and sleeved on the driven shaft 402, without affecting the magnetic attraction between the main electromagnetic assembly 404 and the auxiliary electromagnetic assembly 405; a circular clamping plate II is also coaxially fixed on the rear end face of the auxiliary electromagnetic assembly 405, and the inner diameter of clamping plate II matches the outer diameter of clamping plate I. The outer diameter of clamping plate I is smaller than the outer diameter of the auxiliary electromagnetic assembly 405, and it is coaxially spaced and sleeved on the driven shaft 402, without affecting the magnetic attraction between the main electromagnetic assembly 404 and the auxiliary electromagnetic assembly 405; The magnetic attraction between the magnetic component 404 and the auxiliary electromagnetic component 405 has no effect; a cutter head I 406 is also provided on the inner circumferential surface of the clamping plate II. When the large reel 410 finishes winding, the auxiliary electromagnetic component 405 moves horizontally toward the main electromagnetic component 404 through the action of the main electromagnetic component 404. Then, through the cooperation of the clamping plate I and the clamping plate II, the optical fiber 3 wound on the main electromagnetic component 404 and the auxiliary electromagnetic component 405 is clamped, and then the optical fiber 3 is cut by the cutter head I 406.

[0025] like Figures 1-3 As shown, a clamping block 416 is coaxially sleeved on the driven shaft 402 relative to the fixed frame 401 and the fixed plate 403. The clamping block 416 has a U-shaped cross-section, and its inner diameter matches the diameter of the fixed plate 403, ensuring that its open end faces the fixed plate 403. The clamping block 416 is mounted on the upper end of the bracket II 418 via a bearing seat, and the lower end of the bracket II 418 is fixedly mounted on the moving end of the moving mechanism III 419, and the moving mechanism III 419 separates the area between the fixed frame 401 and the fixed plate 403. The field performs horizontal longitudinal reciprocating motion; the clamping block 416 and the bearing seat rotate around their own axis, and a miniature cylinder is also horizontally longitudinally provided on its inner circumference near its rear inner side. The telescopic end of the miniature cylinder is horizontally longitudinally forward and connected to the cutter head II 417. Then, driven by the moving mechanism III 419, the optical fiber 3 wound on the main electromagnetic assembly 404 is clamped by the cooperation of the clamping block 416 and the fixed plate 403. When the optical fiber 3 is switched to the right take-up mechanism 8, the optical fiber 3 is cut by the cutter head II 417. The moving mechanism III 419 of this invention is a conventional structure that can drive the bracket II 418 to move horizontally, such as a screw and nut structure. This is prior art, so its specific structure will not be described in detail here.

[0026] like Figures 1-3As shown, the internal depth of the clamping block 416 is greater than the thickness of the fixing plate 403, and it must be ensured that when the optical fiber 3 is clamped by the clamping block 416 and the fixing plate 403, the fixing plate 403 does not interfere with the extension and retraction of the micro cylinder; the retraction limit position of the micro cylinder must be ensured that when the optical fiber 3 is clamped by the clamping block 416 and the fixing plate 403, the cutter head II 417 will not cut the optical fiber 3; the extension limit position of the micro cylinder must be ensured that when the optical fiber 3 is clamped by the clamping block 416 and the fixing plate 403, the cutter head II 417 can cut the optical fiber 3.

[0027] like Figures 1-3 As shown, a left auxiliary wheel 5 is vertically and horizontally arranged between the left take-up mechanism 4 and the pressure roller 6. The left auxiliary wheel 5 is set independently of the left take-up mechanism 4 and the pressure roller 6, and moves horizontally and vertically through the drive mechanism II (not shown in the figure). The fixed end of the drive mechanism II is fixedly set at the corresponding position on the front surface of the fixed frame 401, and its extension limit position must ensure that the left auxiliary wheel 5 can extend to the position relative to the fixed plate 403, thereby assisting the take-up switching between the left take-up mechanism 4 and the right take-up mechanism 8 through the left auxiliary wheel 5. A right auxiliary wheel 7 is vertically and horizontally arranged between the right take-up mechanism 8 and the pressure roller 6, and the right auxiliary wheel 7 is vertically and horizontally arranged between the right take-up mechanism 8 and the pressure roller 6. The pressure rollers 6 are set up independently and move horizontally and longitudinally through the drive mechanism III (not shown in the figure). The fixed end of the drive mechanism III is fixedly set at the corresponding position on the front surface of the fixed frame 401, and its extension limit position must ensure that the right auxiliary roller 7 can extend to the position relative to the fixed plate 403. Then, the right auxiliary roller 7 assists in the switching of wire take-up between the left take-up mechanism 4 and the right take-up mechanism 8. The extension limit position of the drive mechanism I must ensure that the pressure roller 6 can extend to the position relative to the fixed plate 403, and its descent limit position must ensure that the pressure roller 6 is located below the main electromagnetic assembly 404. Then, the pressure roller 6 assists in the switching of wire take-up between the left take-up mechanism 4 and the right take-up mechanism 8.

[0028] The present invention provides a method for preventing whiplash in a high-speed fiber optic switching anti-whiplash device, such as... Figures 1-3 As shown, it includes the following steps: Step 1: First, the large disc 410 is coaxially installed on the large disc fixing mechanism 411 of the left take-up mechanism 4. Then, driven by the moving mechanism II 415, the large disc 410 moves horizontally and longitudinally with the drive shaft 412 and is locked in place with the auxiliary electromagnetic component 405, thus completing the assembly of the left take-up mechanism 4.

[0029] Step 2: Then, driven by the servo motor 413 of the left take-up mechanism 4, the corresponding large disk 410, main electromagnetic component 404 and auxiliary electromagnetic component 405 rotate with the drive shaft 412; then, driven by the moving mechanism I2, the cable is laid out through the cable guide wheel group 1, and the optical fiber 3 is taken up onto the large disk 410 of the left take-up mechanism 4; at the same time, the next large disk 410 is installed on the right take-up mechanism 8 and is in standby state.

[0030] Step 3: After the large reel 410 on the left take-up mechanism 4 has finished taking up the wire, the optical fiber 3 is wound around the auxiliary electromagnetic component 405 with the winding groove I 407, and then wound around the main electromagnetic component 404 with the winding groove II 408. At this time, through the action of the main electromagnetic component 404, the auxiliary electromagnetic component 405 moves horizontally towards the main electromagnetic component 404. Then, through the cooperation of clamping plate I and clamping plate II, the optical fiber 3 wound around the main electromagnetic component 404 and the auxiliary electromagnetic component 405 is clamped, and then the optical fiber 3 is cut by the cutter head I 406. At the same time, under the drive of the servo motor 413 of the right take-up mechanism 8, the large reel 410, the main electromagnetic component 404 and the auxiliary electromagnetic component 405 rotate in opposite directions.

[0031] Step 4: Then the optical fiber 3 continues to be wound around the main electromagnetic component 404. At this time, under the drive of the moving mechanism Ⅲ419, the optical fiber 3 wound around the main electromagnetic component 404 is clamped by the cooperation of the clamping block 416 and the fixing plate 403.

[0032] Step 5: Then, driven by the moving mechanism I2, the cable guide wheel group 1 moves horizontally to directly above the right take-up mechanism 8. With the assistance of the pressure wheel 6, the left auxiliary wheel 5, and the right auxiliary wheel 7, the optical fiber 3 is placed on the large reel 410 of the right take-up mechanism 8. At the same time, driven by the micro cylinder, the cutter head II 417 cuts the optical fiber 3 on the main electromagnetic component 404. At this time, the optical fiber 3 begins to be taken up on the large reel 410 of the right take-up mechanism 8 under the cable guide wheel group 1, thus completing the take-up switch between the left take-up mechanism 4 and the right take-up mechanism 8. At this time, the large reel 410 on the left take-up mechanism 4 can be disassembled and replaced.

[0033] The beneficial effects of this invention are: (1) By using the main electromagnetic component 404 and the auxiliary electromagnetic component 405 together, the present invention ensures that the fiber head does not hit the large disk 410, fundamentally solving the whipping problem of the fiber 3, thereby ensuring the normal operation of production and ensuring the quality of the fiber 3. (2) The present invention facilitates the switching between the left take-up mechanism 4 and the right take-up mechanism 8 when the optical fiber 3 is at high speed by using the moving mechanism Ⅲ419, the clamping block 416, the cutter head Ⅱ417 and the pressure roller 6 in cooperation, thereby ensuring the normal operation of production. (3) The present invention ensures the stability of the switching process by using the left auxiliary wheel 5 and the right auxiliary wheel 7 in combination.

Without departing from the design concept of the present invention, all modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope of the present invention.
