Description

Technical Field

[0001] The present invention provides an optical fiber threading machine specially used for optical fiber manufacturing, and particularly relates to the technical field of optical fiber manufacturing. Background Art

[0002] Fiber threading is the process of inserting the optical fiber into the connector / plug, connecting the optical fiber with the components inside the connector / plug to form a reliable connection. It is one of the core links in the manufacturing of optical fiber communication equipment.

[0003] A utility model patent, published as CN219758547U, discloses a fiber-threading device for optical fiber connectors. This device uses a slide rail to move an optical fiber, held by a positioning assembly, into the connector for threading. Furthermore, an invention patent, published as CN117483289A, discloses an automatic wiping device for large-diameter multi-core optical fibers. This device uses a wiping mechanism to automatically clean the fiber end face upon detecting contamination, eliminating the need for manual wiping and offering high precision and efficiency.

[0004] The above-mentioned prior art (reference documents) still has deficiencies: First, during fiber threading, the single-point clamping method used makes it difficult to provide uniform and stable radial clamping force on the fiber. This makes the fiber prone to microbend losses and even physical breakage during insertion into the connector / plug, leading to threading failures, low threading efficiency, and increased costs. Furthermore, traditional clamping methods are mostly rigid, with hard contact on the fiber, which can cause irreversible wear on the fiber surface, damage the fiber's structural integrity, and ultimately affect the quality and stability of fiber-optic communication transmission.

[0005] Second, the fiber surface cleaning effect during the fiber threading process is poor. Existing automatic wiping solutions can only act on one side of the fiber surface or end face, and cannot fully cover the entire outer periphery and end face of the insertion end, resulting in incomplete cleaning. Residual dust and impurities will increase the insertion loss between the fiber and the connector, interfering with the stability and efficiency of signal transmission. On the other hand, the long-term accumulation of attached contaminants may also corrode the contact interface between the fiber and the connector, affecting their physical properties and communication performance, increasing subsequent maintenance costs and the risk of failure, and restricting the overall quality of the fiber threading operation and the reliability of the communication system.

[0006] Therefore, the present invention proposes an optical fiber threading machine specifically used for optical fiber manufacturing to make up for the shortcomings of the prior art. Summary of the Invention

[0007] In view of the defects in the prior art, the present invention provides an optical fiber threading machine specifically used for optical fiber manufacturing, which can effectively solve the relevant technical problems raised by the background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention discloses an optical fiber threading machine specially used for optical fiber manufacturing, comprising a base, a fiber threading drive unit arranged on the top of the base; a fiber threading platform is connected to the fiber threading drive unit; It also includes: a feeding positioning mechanism, which is arranged on the top surface of the fiber threading platform; It includes a pump body installed on the outer wall of one side of the fiber threading table, the output gas end on the top of the pump body is connected to the main body, and the main body is connected to at least three auxiliary pipes on the side away from the pump body. The auxiliary pipes are retractable structures, and each auxiliary pipe is connected to at least three concave pipes on the side away from the main body, and the concave pipes are equidistantly distributed along the axial direction of the auxiliary pipes. The lower end of each concave pipe is connected to a branch pipe, and there are two branch pipes on the corresponding concave pipes. Positioning blocks are fixedly installed on the outside of the two branch pipes, and an inner concave portion is provided on the side where the two positioning blocks are close to each other, and an air bag that matches its shape is provided on the inner concave portion, and the air bag is connected to the branch pipe on the corresponding side; All the inner recesses and air bags under the same auxiliary tube are on the same horizontal axis; A distance adjustment component is provided between the feeding positioning mechanism and the fiber threading platform. The distance between each airbag on the same auxiliary tube body is synchronously adjusted by the adjustment component, and the distance adjustment component provides a smooth connection between each positioning block and the top of the fiber threading platform.

[0009] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: This fiber threading machine, designed specifically for optical fiber manufacturing, uses an airbag expansion method to clamp the fiber. Compared to traditional rigid clamping, this method can avoid scratches, indentations, and other damage to the fiber surface, ensuring the integrity and performance of the fiber. The semi-cylindrical arc-shaped concave portion and the airbag fit tightly against the fiber surface. Multi-point clamping combined with ribs increases friction. The evenly spaced airbags form a three-point linear constraint, reducing the "catenary bend" of the suspended fiber section, keeping the fiber stable during threading and less prone to damage, thereby improving threading efficiency. By controlling the air path through the solenoid valve, it is possible to clamp different numbers of optical fibers in different positions individually or in batches, meeting diverse fiber threading needs and improving the applicability and flexibility of the fiber threading machine. The retractable auxiliary tube design enables the positioning mechanism to adapt to different structural changes during adjustment, ensuring the normal operation of the air path system and enhancing the stability and reliability of the entire mechanism. The servo motor and ball screw work together to achieve high-precision positioning of the fiber threading platform, meeting the stringent fiber threading position requirements during optical fiber manufacturing and reducing fiber threading failures caused by positioning errors. The guiding action of the twin rods and the anti-friction design of the bearings ensure that the fiber threading platform remains stable during movement, preventing damage to the optical fiber caused by shaking and improving the reliability of the fiber threading machine. The combination of the servo motor and ball screw achieves fast and efficient power transmission, shortening the movement time of the fiber threading platform and improving the efficiency of fiber threading. When the semi-cylindrical barrel is closed, a complete cylindrical cavity is formed. Cooperating with the rotating wiping component, full coverage cleaning of the outer peripheral surface and end face of the optical fiber insertion end is achieved. Compared with traditional single-sided wiping, the cleaning coverage rate is greatly improved, which significantly improves the optical fiber threading quality and the long-term reliability of the communication system.

[0012] The present invention will be further described below with reference to the embodiments.

[0013] Example 1: like Figures 1 to 5 As shown, an optical fiber threading machine specifically used for optical fiber manufacturing includes a base 1, a fiber threading drive unit, which is arranged on the top of the base 1, and a fiber threading platform 11 is connected to the fiber threading drive unit, which is moved horizontally on the base 1 by the fiber threading drive unit; The fiber threading drive unit includes a servo motor 12 mounted on the top side of the base 1, away from the fiber threading platform 11. A lead screw 13 is coaxially connected to the output shaft of the servo motor 12. The end of the lead screw 13, away from the servo motor 12, is rotatably connected to the top sidewall of the base 1. The lead screw 13 is securely connected to the output shaft of the servo motor 12 via a coupling. A bearing, typically a deep-groove ball bearing (model 6205), is installed at the connection between the lead screw 13 and the base 1 to carry radial loads and reduce rotational friction. Lead screw 13 is threaded through the bottom of the fiber threading platform 11 and forms a ball screw structure with the platform 11. The servo motor 12 can be a Panasonic MINASA6 series servo motor (model MSMF042L1UM), rated at 400W, 3000 rpm, and with a positioning accuracy of ±0.01mm. This meets the requirements of a ball screw drive and ensures the stability and precision of the movement of the fiber threading platform 11. The top of the base 1 is symmetrically fixed with twin rods 14 on both sides of the screw rod 13. The bottom of the fiber threading platform 11 is slidably connected to the twin rods 14. That is, through holes are provided on both sides of the bottom of the fiber threading platform 11 for the twin rods 14 to pass horizontally.

[0014] The fiber is fed to the positioning mechanism, which is arranged on the top surface of the fiber threading platform 11; It includes a pump body 21 mounted on the outer wall of one side of the fiber threading platform 11. The gas output end at the top of the pump body 21 is connected to the main body 22. At least three auxiliary pipes 23 are connected to the side of the main body 22 away from the pump body 21. Each auxiliary pipe 23 is installed with a diverter solenoid valve at the point where it connects to the main body 22. The main solenoid valve is installed at the point where the main body 22 connects to the pump body 21. The auxiliary pipes 23 are retractable structures. Specifically, the auxiliary pipes 23 can be bellows or axially retractable pipes. At least three concave tubes 28 are provided on the side of each auxiliary tube 23 away from the main tube 22, and the concave tubes 28 are equidistantly distributed along the axial direction of the auxiliary tube 23. The lower end of each concave tube 28 is connected to a branch tube 27. There are two branch tubes 27 on the corresponding concave tube 28. A positioning block 24 is fixedly installed on the outside of each branch tube 27. The two positioning blocks 24 are provided with an inner concave portion 25 on the side close to each other, and an air bag 26 with a shape adapted to the inner concave portion 25 is provided on each inner concave portion 25. The air bag 26 is connected to the branch tube 27 on the corresponding side. Each recessed portion 25 and air pocket 26 located beneath the same auxiliary tube 23 lies on the same horizontal axis. Specifically, optical fibers can pass horizontally between the air pockets 26 located beneath the same auxiliary tube 23. Each air pocket 26 is evenly spaced along the axial direction of the auxiliary tube 23. When air is injected and expanded, the air pockets 26 exert a flexible clamping force on the optical fibers. Connectors corresponding to the position and number of optical fibers are located on the top side of the base 1, away from the fiber insertion platform 11. These connectors are stably placed atop the base 1 using a conventional loading mechanism. Specifically, the loading mechanism can be a tray with grooves that match the external shape of the connectors, or a conventional clamping fixture. Note: This loading mechanism is not illustrated in the figure as prior art, but may be included in the accompanying drawings.

[0015] In a specific implementation, the inner recess 25 and the air bag 26 are semi-cylindrical arc-shaped, and two corresponding inner recesses 25 and air bags 26 are formed with holes for the optical fibers to pass through.

[0016] Optionally, as another embodiment, the shape of the inner recess 25 and the air bag 26 is not limited to a semi-cylindrical arc, and other shapes that can allow the optical fiber to pass through and clamp can be adopted, such as V-shape, rectangle, non-semi-cylindrical arc, etc.

[0017] In a specific implementation, ribs are provided on the surfaces of the two airbags 26 that are close to each other. The ribs are made of rubber, and there are multiple ribs evenly arranged and distributed equidistantly on the airbags 26. The ribs increase the friction force in contact with the optical fiber surface and provide a stable clamping force.

[0018] During use: First, turn on pump 21, which generates compressed air that is delivered through main pipe 22. By controlling the main and branch solenoid valves, the compressed air can be directed to each auxiliary pipe 23. The auxiliary pipes 23 utilize an axially retractable structure, allowing them to adapt to length changes during subsequent adjustments, ensuring air flow connectivity.

[0019] Compressed air enters the concave tubular body 28 through the auxiliary tube 23, and then enters the airbag 26 through the branch tube 27. Once inflated, the airbag 26 expands. Because the inner recess 25 and the airbag 26 are semi-cylindrical arcs, the expanded airbag 26 fits tightly against the cylindrical surface of the optical fiber, creating a flexible clamping force that securely holds the fiber. Multiple airbags 26, evenly spaced axially below the same auxiliary tube 23, achieve multi-point clamping of the optical fiber, ensuring horizontal stability. Ribs on the surface of the airbag 26 increase friction with the optical fiber surface, further enhancing clamping stability and preventing slippage during fiber threading.

[0020] Then, the servo motor 12 is started again, and the output shaft of the servo motor 12 drives the screw 13 to rotate. A bearing is installed at the connection between the screw 13 and the base 1 to reduce rotational friction and ensure smooth rotation of the screw 13. Since the screw 13 and the fiber threading platform 11 form a ball screw structure, the rotational motion of the screw 13 is converted into the horizontal linear motion of the fiber threading platform 11. At the same time, the through holes on both sides of the bottom of the fiber threading platform 11 are sleeved on the twin rods 14. The twin rods 14 play a guiding role, limiting the deviation or shaking of the fiber threading platform 11 during movement, ensuring that the fiber threading platform 11 can achieve stable horizontal movement on the base 1. The servo motor 12 accurately controls the rotation angle and speed through the control system, thereby accurately controlling the moving distance and position of the fiber threading platform 11. This drives the above-mentioned clamped and positioned optical fiber to be inserted into the corresponding connector to realize the fiber threading operation.

[0021] After the optical fiber threading operation is completed, the pump body 21 is closed or the air release valve is opened, the gas in the air bag 26 is discharged, the air bag 26 retracts, and the optical fiber is released.

[0022] Example 2: like Figure 1 、 Figures 6 to 8 As shown, the optical fiber threading machine further includes a distance adjustment component disposed between the feed positioning mechanism and the threading platform 11. The distance between the air bags 26 on the same auxiliary tube 23 is synchronously adjusted by the adjustment component, and the distance adjustment component provides a stable connection between the positioning blocks 24 and the top of the threading platform 11. The distance adjustment assembly includes a bottom plate body 31 fixedly connected to the bottom of each positioning block 24, and the bottom of each bottom plate body 31 is fixedly connected to an extension shaft 32. Each extension shaft 32 is commonly connected to a combined hinge frame 35. The combined hinge frame 35 is composed of at least six connecting rods, and the two ends of the two connecting rods located in the middle are respectively rotatably connected to another connecting rod, and the ends of the two other connecting rods away from the two middle connecting rods are rotatably connected. Specifically, the structural features of the combined hinge frame 35 can also be seen from Figure 6 It is further understood that the two longer connecting rods in the middle are connected to a central extension shaft 32 in a cross-shaped manner, and the connecting rods form a parallelogram connecting rod structure. A slot block 34 is fixedly installed at the bottom of each extension shaft 32. A slot plate 33 is fixedly installed on the top surface of the fiber threading platform 11 at a position corresponding to each slot block 34. Each slot block 34 is slidably installed in the corresponding slot plate 33. The bottom plate 31, extension shaft 32, slot plate 33, slot block 34, and combined hinge frame 35 are installed at the bottom of each positioning block 24 and are indirectly connected to the top of the fiber threading platform 11 through the slot plate 33 to ensure that each positioning block 24 is stably installed on the top of the fiber threading platform 11. In a specific implementation, an adjusting component 36 for adjusting the position of one of the extension shafts 32 and the slot block 34 is provided on one side of the slot plate 33; Specifically, such as Figure 3 and Figure 6 As shown, the adjusting component 36 is located on the slotted plate 33 and away from the side of the screw rod 13. The adjusting component 36 is configured as a threaded rod, which is rotatably connected to the top of one side of the slotted plate 33, and the threaded rod passes through the middle of one of the extension shafts 32 and is threadedly connected to the middle of the extension shaft 32. As another optional embodiment, the adjusting component 36 can also be configured as: a moving structure, including a gear rack transmission structure, an electric telescopic rod, etc., not limited to the structural features proposed in this embodiment, and other structures that can drive one of the extension shafts 32 to move horizontally can be adopted.

[0023] During use, the threaded rod of the adjustment component 36 is rotated to drive one of the extension shafts 32 to move horizontally along the slot plate 33. The parallelogram-shaped linkage structure of the combined articulated frame 35 forces the other extension shafts 32 to move synchronously, thereby driving all positioning blocks 24 on the same auxiliary tube body 23 to adjust their spacing evenly. The combined articulated frame 35 ensures the synchronous movement of each positioning block 24, and the telescopic auxiliary tube body 23, such as a bellows, automatically compensates for length changes during spacing adjustment, maintaining air flow connectivity.

[0024] Example 3: like Figure 1 、 Figures 9 to 11As shown, the above-mentioned optical fiber threading machine also includes an active processing mechanism arranged on the top of the fiber threading platform 11 and close to the side of the screw rod 13, which includes a support frame 41 fixedly connected to the top of the fiber threading platform 11, and at least three first electrically controlled telescopic rods 42 are fixedly installed on the top of the support frame 41. A micro motor 43 is fixedly installed on the telescopic end at the bottom of each first electrically controlled telescopic rod 42, and a concave plate 44 is connected to the output shaft of the micro motor 43 through a coupling. Two second electrically controlled telescopic rods 45 are symmetrically installed on the side of the concave plate 44 away from the micro motor 43. The two second electrically controlled telescopic rods 45 are symmetrically installed on the telescopic ends of the sides close to each other. They are respectively fixedly connected with a semi-cylindrical body 46, a wiping component 47 is provided inside the semi-cylindrical body 46, a center hole 48 is formed in the middle of the wiping component 47, the wiping component 47 is configured as a semi-cylindrical sponge, and a plurality of array protrusions 471 are evenly provided on the outer surface of the wiping component 47, at least three semi-ring plates 461 are fixedly provided on the inner cylinder wall of the semi-cylindrical body 46, each semi-ring plate 461 is provided with an identical array groove 462 corresponding to each array protrusion 471, the wiping component 47 is inserted into the array groove 462 through the array protrusion 471, and then installed inside the semi-cylindrical body 46.

[0025] The first electrically controlled telescopic rod 42 and the second electrically controlled telescopic rod 45 are made of AirTac ACQ series electric cylinders (ACQ63100 model is optional), with a positioning accuracy of ±0.2mm, supporting PLC control, and realizing linkage with the positioning mechanism.

[0026] Micro motor 43: A Maxon DC micro motor (e.g., model RE30) is used, with a power of 30W and a rotation speed of 5000 r / min, which drives the concave plate 44 to rotate through a coupling.

[0027] In use: Initially, the two semi-cylindrical bodies 46 are held closed by a second electrically controlled telescopic rod 45, and the axis of the central hole 48 of the wiping member 47 is pre-aligned with the axis of the optical fiber. After the optical fiber is clamped by the positioning mechanism, the fiber insertion drive unit drives the fiber insertion platform 11 to move horizontally, actively extending the portion of the optical fiber to be cleaned into the closed central hole 48, ensuring that the optical fiber and the wiping member 47 are coaxial.

[0028] Subsequently, the micro motor 43 drives the concave plate 44 to rotate, driving the semi-cylindrical barrel 46 and the wiping member 47 to rotate around the optical fiber axis. The semi-cylindrical sponge of the wiping member 47 contacts the surface of the optical fiber, and the circumferential friction generated by the rotation removes impurities such as dust and oil.

[0029] After a preset cleaning time, such as 10 seconds, has elapsed, the second electrically controlled telescopic rod 45 drives the two semi-cylindrical bodies 46 away from each other. The first electrically controlled telescopic rod 42 then drives the semi-cylindrical bodies 46 upward, freeing the wiping member 47 from the optical fiber to prevent interference with fiber threading. The fiber threading drive unit then moves the fiber threading platform 11, delivering the cleaned optical fiber to the connector or fiber threading hole, completing the subsequent fiber threading operation.

[0030] As another embodiment, an external interface is provided on the semi-cylindrical body 46. If the cleaning effect needs to be enhanced, a small amount of alcohol or deionized water can be injected into the wiping member 47 through the external pipe to achieve wet cleaning during the rotation process.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that: it should be understood that in the present application, the rotating, sliding, and other moving / transmission components are well lubricated and not prone to slipping or wear, and the driving and transmission components are provided with corresponding protective shells on the outside.
