Description

Technical Field

[0001] This invention relates to the field of optical fiber production, and in particular to an automatic optical fiber drawing device and its usage method. Background Art

[0002] Fiber optic lead-in refers to the process of precisely guiding the optical fiber from its initial state and passing it through specific channels in a mold or other processing equipment during the optical fiber production process. This operation is crucial to ensuring that the optical fiber maintains a stable and accurate position in subsequent processing and handling stages. The fiber optic lead-in process requires highly precise control to avoid bending, twisting, or breaking of the optical fiber during the guiding process, ensuring that the produced optical fiber has consistent quality and performance.

[0003] Chinese patent application number CN201810045813.0 discloses an automatic fiber optic fiber guiding device and method. The method involves taking an optical fiber that has reached the perforation condition, having it detected by a fiber optic detector, clamping it with a fiber optic clamping mechanism, and then transferring it via a transfer mechanism that moves along a slide rail after passing through positioning wheels to move the clamping mechanism above a mold. Once the mold opens, the clamping mechanism is released, and after the fiber passes through the mold and reaches the next positioning wheel, the mold closes, thus completing the automatic fiber optic perforation and fiber guiding process. This process eliminates manual intervention, improves the success rate of fiber guiding, and reduces production delays. However, the above patent and existing technologies have the following problems in practical use: the fiber end is prone to bending during transmission, lacks clamping, has weak adaptability, and requires manual adjustment before reintroduction, leading to reduced work efficiency and affecting overall performance.

[0015] Preferably, the specific steps are as follows:

[0016] S1 Inserting optical fiber: Inserting the optical fiber from the previous process into the guide groove inside the cylinder, passing through the entire guide groove.

[0017] S2 Push Down: Start the first motor, drive the rotating rod to rotate, the rotating rod acts on the connecting rod, push the swing arm, the swing arm drives the actuating rod, and start to move the follower. The limiting part is stably guided and limited during the swing arm movement. After the follower is moved, the connecting shaft rotates, driving the follower rod to act on the push rod. The slider moves down in the guide groove at the lower end of the fixed frame. Start the first cylinder, the pressure pad moves to contact the support pad, clamps the optical fiber, the slider moves down, pushes the optical fiber downward, the actuating rod moves up, drives the follower to move up, then the slider moves up. When the whole moves up, the first cylinder resets, releases the optical fiber clamping, and the cycle achieves stable pushing.

[0019] S4 End Limiting Clamp: With the stable pushing device, the optical fiber enters the limiting clamping mechanism. The sensor detects the optical fiber, starts the second motor, drives the threaded rod to rotate, pushes the push block to move, and with the help of two sets of limiting posts, the linkage rod rotates. The linkage rod drives the pull arm to rotate the rotating disks at the upper and lower ends. The internal through groove pulls the pressure block, and the pressure block moves to clamp the end of the optical fiber.

[0020] S5 feeds the mold in: The fourth motor is started, which drives the active pulley to rotate, which in turn drives the synchronous belt and the driven pulley to rotate. The driven pulley drives the pull rod, which moves the blocking part out of the round hole, exposing the optical fiber. The second cylinder is started, and the support plate moves down to the top of the mold. The third motor is started, and the angle of the support plate is adjusted to match the mold receiving angle. Under the action of the second cylinder, the support plate contacts the mold, and the optical fiber through hole corresponds to the mold receiving hole. The stable pushing device pushes the optical fiber in, and the limit clamping mechanism is released, realizing the introduction of the optical fiber into the mold.

[0021] The beneficial effects of this invention are as follows: This invention incorporates a stable pushing device that receives the optical fiber from the previous workstation and intermittently pushes it downwards without requiring manual pushing. This provides high stability. Furthermore, an adjustment device is located below the stable pushing device, with a limiting clamping mechanism connected to its upper end.

Rotating disks 37 are respectively provided on the upper end of the fixed shell 36 and the top of the base 310. One end of each of the two sets of rotating disks 37 protrudes and is hinged to the corresponding pull arm 35. A fixed guide disk 38 is provided between the two sets of rotating disks 37. A pressure block 39 is movably embedded in the four ends of the fixed guide disk 38. A fourth motor 311 is provided on the top right end of the base 310.

[0039] The top of the fixed guide plate 38 has two sets of strip grooves corresponding to the two sets of pressure blocks 39, and the bottom two sets of strip grooves correspond to the other two sets of pressure blocks 39. The upper and lower rotating plates 37 also have through grooves corresponding to the upper and lower strip grooves. The pressure block 39 is provided with a protruding rod at the position corresponding to the strip groove. The protruding rod passes through the strip groove and extends into the through groove. The inner side of the pressure block 39 is arc-shaped and flexible.

[0040] The right end of the chassis 310 is provided with a drive pulley 312 that connects to the fourth motor 311. The outer side of the drive pulley 312 rotates synchronously with the driven pulley 314 via a synchronous belt 313. The left end of the bottom of the driven pulley 314 is provided with a pull rod 315. A blocking member 316 that can block the round hole is fixed on the left side of the pull rod 315. The right end of the chassis 310 is provided with an arc-shaped groove 317. The top protrusion of the pull rod 315 can be movably embedded into the arc-shaped groove.

[0041] A pressure sensor or touch sensor can be installed in the middle of the blocking component 316 to sense whether it is in contact with the optical fiber, and it needs to be connected to an external main control device for electrical signal transmission.

[0042] The specific implementation process is as follows:

[0043] When it is necessary to introduce the optical fiber into the mold, the optical fiber is first inserted from the previous process into the guide groove 1132 inside the cylinder 1131 and passes through the entire guide groove 1132. Then, the first motor 1a is started to work. The first motor 1a drives the rotating rod 12 to rotate. The rotating rod 12 acts on the connecting rod 13 to push the swing arm 14. The swing arm 14 can then drive the actuating rod 15 to start to move the follower 18. During the movement, the limiting member 16 swings and fits the fitting member 19 to stabilize and guide the movement. After the follower 18 is moved, the connecting shaft 17 can rotate. The connecting shaft 17 drives the follower rod 110 to act on the push rod 111, so that the slider 112 moves down in the guide groove at the lower end of the fixed frame 11. Before moving down, the first cylinder 114 is started to move the pressure pad 1134 to contact the support pad 1133 to clamp the optical fiber. With the movement of the slider 112, the optical fiber can be pushed downward.

[0044] When the lever 15 moves upward, it can move the follower 18 upward, thereby enabling the slider 112 to move the cylinder 1131 upward. When the whole moves upward, the first cylinder 114 resets with the pressure pad 1134, releasing the clamping of the optical fiber, thereby achieving stable pushing in a cycle.

[0045] When the fiber needs to be clamped and fed into the mold, since the fiber feeding end is prone to bending, the second cylinder 212 is activated to act on the support rod 213 to adjust the height of the top plate 22 connected to the top. The two sets of guide rods 214 at both ends guide the adjustment. When the limiting clamping mechanism 3 is adjusted to the appropriate receiving position, the third motor 23 is activated to rotate the rotating part 24. The top of the rotating part 24 is tilted, so that the connecting part 25 connected to the top rotates eccentrically. During the rotation, the right side is guided and supported by the connecting part 26 on the guide support rod 27, so that the top support plate 28 and the limiting clamping mechanism 3 can be adjusted to match the angle of the fiber end.

[0046] After the angle is aligned, the optical fiber enters the limiting clamping mechanism 3 with the push of the stabilizing push device 1. When the sensor of the internal blocking component 316 senses the optical fiber, the second motor 3a is started to rotate the threaded rod 32. During the rotation of the threaded rod 32, the push block 33 moves. When the push block 33 moves, it cooperates with the two sets of limiting posts to realize the rotation of the linkage rod 34. The rotation of the linkage rod 34 causes the rotating disks 37 at the upper and lower ends to rotate through the pull arm 35. During the rotation, the through groove inside can pull the pressure block 39, so that the pressure block 39 moves in the fixed guide disk 38 and merges towards the center to clamp the end of the optical fiber.

[0047] After clamping, it needs to be sent into the mold and the fourth motor 311 is started. The fourth motor 311 drives the active pulley 312 to rotate. The active pulley 312 rotates and drives the synchronous belt 313 to make the driven pulley 314 rotate. During the rotation of the driven pulley 314, the pull rod 315 can be pulled to make the blocking part 316 move out of the round hole and expose the optical fiber.

[0048] Finally, the second cylinder 212 is activated to move the entire assembly downwards, causing the support plate 28 to move above the mold. Then, the third motor 23 is activated to adjust its angle to match the mold's receiving angle. After adjustment, the second cylinder 212 causes the support plate 28 to contact the mold, with its internal through-hole corresponding to the mold's receiving hole. Finally, with the push of the stabilizing pushing device 1 and the release of the limiting clamping mechanism 3, the optical fiber is introduced.
