[0002] When manufacturing fiber optic components such as FA, MPO adapters, and optical splitters, pre-packaged materials are typically used. This means that multiple optical fibers are bundled together in a rigid acrylic sheath. While this structure facilitates manual assembly, it has significant drawbacks in subsequent processing. The process requires manual operation of equipment for rough cutting, manual reassembly of the scattered fibers, and finally manual clamping and fixing. The entire process is time-consuming, requires multiple skilled operators to work together, resulting in high labor costs, discrete processes, poor consistency in the final product positioning, and the fiber is prone to bending or scratching during the process. This makes it difficult to meet the needs of high-precision, mass production, and flexible manufacturing. Summary of the Invention

[0041] like Figures 1 to 11As shown, the fully automatic fiber feeding and cutting equipment provided by the present invention includes: a fiber feeding mechanism, a fiber gathering mechanism 20, a fiber guiding mechanism 30, a fiber arranging mechanism 40, a fiber cutting unit, and a fiber pulling mechanism 60. The fiber feeding mechanism includes multiple fiber feeding units 10 for releasing single bare fibers. Each fiber feeding unit 10 includes a rotatable bare fiber spool 11 and a floating tension disc 12 located below and to the side of the bare fiber spool 11. The fiber gathering mechanism 20 includes a number of fiber gathering discs 21 equal to the number of fiber feeding units 10. All fiber gathering discs 21 are rotatably mounted on the same support shaft 22. Some fiber feeding units 10 also include a guide disc 13 located between the tension disc 12 and the fiber gathering discs 21. The fiber guiding mechanism 30 includes spaced-apart fiber guiding wheels 31 and fiber guiding blocks 32, with adjustable spacing channels on the fiber guiding blocks 32. The fiber arranging mechanism 40 includes a fixture 41 with a fiber feeding groove 411 on its upper surface, and the fixture 41 is liftable. The fiber cutting unit is located at... Between the pitch adjustment channel and the fiber swaying mechanism 40, the fiber cutting unit includes a laser cutter 51 for cutting the fiber optic cable 1 and a dust extraction system 52 for aligning the cut point; the fiber pulling mechanism 60 includes a gripper 61 that can open and close vertically and a drive unit 62 for driving the gripper 61 to move horizontally. In use, the bare fiber released by the fiber feeding unit 10 passes around the fiber collection tray 21 to form the fiber optic cable 1. After the fiber optic cable 1 passes around the fiber guide wheel 31 to adjust its height, it enters the pitch adjustment channel of the fiber guide block 32. After adjusting the spacing between adjacent bare fibers through the pitch adjustment channel, it flows out from the outlet of the pitch adjustment channel. When the fixture 41 descends, the gripper 61 clamps the fiber optic cable 1 flowing out from the outlet of the pitch adjustment channel and passes over the fiber swaying mechanism 40, so that the fiber optic cable 1 is suspended. When the fixture 41 rises, it can embed the suspended fiber optic cable 1 into the fiber feeding groove 411. After being embedded in place, the fiber cutting unit cuts the fiber optic cable 1, the fixture 41 descends, and the automatic fiber swaying and cutting operation is completed.

[0042] The advantages of this setup are: fewer processes, shorter time, and higher production efficiency. No secondary alignment is required during production, and operators have no contact with the bare fiber throughout the process, preventing bending or scratching of the optical fiber. The products have good consistency and low quality risk. The fixtures and fiber guide blocks can be flexibly changed according to actual needs to adapt to different core counts and spacings of fiber arranging and cutting operations. The fully automatic fiber arranging and cutting only requires a single person to load and unload (bare fiber reel and fixture), making operation simple and less prone to errors.

[0043] To achieve stress-free embedding of the fiber optic cable 1 into the fiber placement groove 411, in this embodiment, the fixture 41 is equipped with a pressure sensor 412 for detecting the pressure on the fiber placement groove 411, and the fiber placement mechanism 40 is equipped with a photoelectric sensor 42 for detecting the position of the end face of the fiber optic cable 1 on its upper side. When the detection values ​​of the pressure sensor 412 and the photoelectric sensor 42 both meet the requirements, it indicates that the fiber optic cable 1 is embedded in place, and at this time, the fixture 41 stops rising.

[0044] To facilitate loading and unloading of the fixture 41, in this embodiment, the fixture 41 includes a base 43, an intermediate plate 44 disposed on the base 43, and a magnetic suction plate 45 disposed on the intermediate plate 44. A fiber feeding groove 411 is disposed on the upper surface of the magnetic suction plate 45. A through hole 441 is provided on the intermediate plate 44. A pressure sensor 412 is disposed on the base 43 and passes through the through hole 441. Magnets 451 are embedded at the four corners of the magnetic suction plate 45. In actual production, it is only necessary to pick up and put down the magnetic suction plate 45, making the operation simpler. To facilitate positioning, the two adjacent sides of the intermediate plate 44 are further connected with upwardly extending fixed blocks 442. The base 43 is provided with a T-shaped groove 431, and two movable slide plates 432 are embedded in the T-shaped groove 431. The slide plates 432 are provided with upwardly extending movable blocks 433 located on the opposite side of the fixed blocks 442. The movable blocks 433 have a tendency to move toward their corresponding fixed blocks 442. To achieve this tendency, a spring-like elastic element is also provided between the slide plates 432 and the base 43.

[0045] Furthermore, one of the slide plates 432 is projected in a Σ shape in the vertical direction, and the other is in an h shape. The middle of the T-shaped groove 431 is provided with a horizontally movable bearing 434. When the Σ-shaped slide plate 432 moves, the power can be transmitted to the h-shaped slide plate 432 through the bearing 434, so that the movable stop 433 on it moves accordingly, and the release is achieved synchronously.

[0046] To enable the movement of the Σ-shaped sliding plate 432, in this embodiment, the end of the Σ-shaped sliding plate 432 extends outward and is provided with a fastening groove 435. The fiber optic mechanism 40 also includes a horizontally movable fastening plate 46 and a cylinder 461 that drives the fastening plate 46 to move horizontally. The fastening plate 46 is provided with a protrusion 462. When the fixture 41 descends, the protrusion 462 extends into the fastening groove 435 from below, so as to achieve the technical effect of moving the two sliding plates 432 synchronously by moving the fastening plate 46 in conjunction with the movement of the bearing 434, so that the movable stop 433 is released synchronously, thereby avoiding the misalignment of the fiber optic cable 1 in the fiber optic cable tray 411 caused by vibration.

[0047] In this embodiment, the photoelectric sensor 42 is mounted on a bracket, which includes uprights 421 on both sides and a crossbar 422 spanning the two uprights 421. A crossbar seat 423 that can move up and down is fitted on the uprights 421. The end of the crossbar 422 is rotatably inserted into the crossbar seat 423. The photoelectric sensor 42 is connected to the crossbar 422. The detection position of the photoelectric sensor 42 can be adjusted by moving the crossbar seat 423 up and down and by rotating the crossbar 422.

[0048] To further improve production efficiency, in this embodiment, there are four fixtures 41 arranged at intervals in a direction perpendicular to the fiber feeding groove 411. The fiber feeding mechanism 40 also includes a lifting unit 47 that supports all fixtures 41, and a transfer unit 48 that drives the lifting unit 47 to move back and forth along the arrangement direction of the fixtures 41.

[0049] In this embodiment, the fiber arranging mechanism 40 also includes a pressure strip 49 that is movable up and down above the fixture 41. The position of the pressure strip 49 corresponds to the guide block 32. The upper surface of the fixture 41 is provided with a mating groove 413 that matches the pressure strip 49. The mating groove 413 is deeper than the fiber feeding groove 411 and penetrates vertically through the fiber feeding groove 411.

[0050] In this embodiment, adjacent bare fibers in the fiber optic busbar 1 are arranged close together. The fiber guide block 32 includes a lower block 321 and an upper cover 322. An adjustment groove 323 is provided on the lower block 321. The upper cover 322 is fastened (removable) to the lower block 321, and together with the adjustment groove 323, they form an adjustment channel. To achieve the adjustment function and ensure smooth operation, the middle part of the adjustment groove 323 extends through the lower block in a direction perpendicular to the adjustment groove 323. The two sides of the middle part of the adjustment groove 323 are the entrance section 324 and the exit section 325, respectively. The entrance and exit ends of the entrance section 324 and the entrance end of the exit section 325 are all flared outwards. The middle part of the entrance section 324 and the exit end of the exit section 325 are straight. The width of the middle part of the entrance section 324 is greater than the width of the exit end of the exit section 325. In other embodiments, the spacing between adjacent bare fibers in the fiber optic busbar 1 can be 0.1-0.5 mm. Figure 12 The lower block 321 of the fiber guide block 32 in another embodiment is shown. It is provided with a group of separator strips 326 at the exit end of the inlet section 324, the inlet end and the outlet end of the outlet section 325. Each group of separator strips 326 includes a plurality of spaced separator strips 327. The spacing between adjacent separator strips 327 in the group of separator strips 326 located at the exit end of the outlet section 325 is the smallest.

[0051] Furthermore, the projection of the upper cover 322 in the vertical direction is C-shaped, and a notch 328 is formed in the middle to expose the adjustment groove 323. The fiber guiding mechanism 30 also includes a rubber block 33 for pressing the fiber optic cable 1 in the adjustment groove 323. The rubber block 33 is movably disposed above the notch 328. The fiber guiding mechanism 30 also includes a rubber block cylinder 34 for driving the rubber block 33 to move up and down.

[0052] In this embodiment, the fiber guiding mechanism 30 further includes a perforated plate 35 disposed between the fiber guiding wheel 31 and the fiber receiving tray 21, and a tension adjusting wheel 36 disposed between the fiber guiding wheel 31 and the fiber guiding block 32. The perforated plate 35 is provided with through holes 351 for the fiber optic cable 1 to pass through, so as to ensure the neatness of the fiber optic cable 1 entering the pitch adjustment channel. The tension adjusting wheel 36 presses on the fiber optic cable 1 flowing out of the fiber guiding wheel 31. The tension adjusting wheel 36 is set to move up and down to ensure that the fiber optic cable 1 entering the pitch adjustment channel is in a taut state.

[0053] In this embodiment, the fiber pulling mechanism 60 further includes a tension adjustment component 63 and a gripper cylinder 64 for mounting the gripper 61. The gripper cylinder 64 is connected to the drive unit 62 through the tension adjustment component 63 to ensure that the tension applied by the gripper 61 to the end of the fiber optic cable 1 remains constant when the drive unit 62 is activated. To prevent detachment and avoid injury, the surfaces of the grippers 61 facing each other are further provided with rubber pads 611.

[0054] The fully automatic fiber cutting and sizing equipment also includes a body 71, a vertical plate 72 and a horizontal plate 73 mounted on the body 71, a fiber feeding mechanism and a fiber gathering mechanism 20 mounted on the vertical plate 72, and a fiber guiding mechanism 30, a fiber sizing mechanism 40, a fiber pulling mechanism 50 and a fiber cutting unit mounted on the horizontal plate 73. For ease of installation, the vertical plate 72 is located at the middle position in the width direction of the horizontal plate 73, and the horizontal plate 73 is located at the middle position in the height direction of the vertical plate 72.

[0055] The use of this fully automatic fiber cutting and trimming equipment includes the following steps: 1. Fiber Optic Preparation: Four independent bare fiber reels release bare fibers respectively. After passing through the tension plate, the bare fibers are merged in the fiber collection plate, and then spatially merged through the pitch adjustment channel of the fiber guide block.

[0056] 2. Fixture preparation: The magnetic plates are manually placed on the middle plate one by one. The buckle plate is retracted, and the slide plate is reset under the action of the elastic element, so that the movable block and the fixed block clamp the magnetic plates to achieve positioning. The repeatability of this positioning can be less than 0.01mm.

[0057] 3. Fiber Pulling: The central controller triggers the gripper cylinder and drive unit to operate according to the preset fiber length parameters (accuracy ±0.05 mm), causing the gripper to clamp the end of the fiber optic cable and move it along a preset trajectory to the starting position. Then, the fiber optic cable is pulled at an adjustable speed of 100mm / s–500mm / s until it reaches the ending position, at which point the fixture rises.

[0058] 4. Cutting: After the detection values ​​of the pressure sensor and photoelectric sensor meet the requirements, the rubber block and pressure strip are pressed down, the laser cutter receives the trigger command and emits a laser beam to cut the fiber optic cable; the beam is focused on the bare fiber surface by the F-θ field lens to achieve vertical cutting without heat-affected zone, the end face roughness Ra≤0.1 μm, and the cutting perpendicularity≤0.3°.

[0059] 5. Unloading: The cut fixture is pushed to the unloading buffer position by the servo transfer mechanism. The operator removes the magnetic suction plate on the fixture. There is no contact with the bare fiber throughout the process, eliminating the risk of contamination and damage.

[0060] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
