Description

Technical Field

[0001] This utility model belongs to the field of optical fiber packaging technology, specifically relating to a dedicated optical fiber take-up and lay-out device. Background Technology

[0002] In early optical fiber production, the laying and winding process was largely manual. When manually packaging bare fibers, workers had to manually pull the fiber from the laying device and then wind it onto the winding device. This process was not only labor-intensive but also inefficient. Manual operation made it difficult to ensure consistent laying and winding speeds, easily leading to uneven stress on the fiber during the process. If the laying speed was too fast, the fiber might break due to excessive tension; if the winding speed was too fast, the fiber might become loose or become tangled, severely affecting fiber quality, resulting in a large number of defective products and increasing production costs.

[0003] With the development of automation technology, some simple fiber take-up and unwinding equipment has emerged, but most of them suffer from functional deficiencies. For example, they lack effective monitoring and control of fiber tension, and cannot adjust the take-up and unwinding speed in real time according to the stress on the fiber. In actual production, fiber tension is affected by various factors, such as the rotational inertia of the bare fiber reel, changes in the rotational speed of the take-up roller, and the inhomogeneity of the fiber's own material. Due to the lack of a precise tension monitoring and control mechanism, fiber breakage frequently occurs during the take-up and unwinding process, seriously affecting the continuity of production and product quality.

[0004] Furthermore, traditional equipment typically lacks automatic meter counting capabilities, making it difficult to accurately control the take-up length during fiber optic assembly. For applications with stringent length requirements, such as fiber optic cable laying in telecommunications engineering, inaccurate length measurement can lead to fiber waste or shortages during construction, increasing costs and complexity. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a dedicated fiber optic cable take-up and lay-out device, which solves the problems of low efficiency, poor packaging quality, inability to monitor fiber tension, and inability to accurately measure the length of existing fiber optic cables using manual methods.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dedicated fiber optic cable laying and take-up device, comprising a laying mechanism and a take-up mechanism. Both the laying and take-up mechanisms include a base and a frame. The frame is mounted on the base. A servo motor is mounted on the frame of the laying mechanism, and a laying shaft and a rotating rod are rotatably mounted thereon. The servo motor is connected to the laying shaft via a synchronous belt transmission mechanism. A locking component, a bare fiber reel, and a quick-lock head for the optical rod are sequentially mounted on the laying shaft. One end of the rotating rod connects to the front rod and the other end of the rear rod. A guide wheel is mounted on the other end of the front rod, and a pull rope is wound around the other end of the rear rod. The pull rope is attached to one end of a rotating plate, and the other end of the rotating plate is connected to the shaft of a tension detector. The tension detector is mounted on a base. The take-up mechanism has a linear guide rail, a touch screen PLC, a control module, and a take-up shaft and a reciprocating screw mounted on its frame. The drive motors of the take-up shaft and the reciprocating screw are fixed on the frame. A take-up roller is slidably mounted on the take-up shaft, and a second quick-lock head is mounted on the take-up shaft on both sides of the take-up roller. The reciprocating screw is threadedly connected to a slider. The slider is slidably connected to the linear guide rail, and a support plate is mounted on the slider. An encoder and a wire nozzle are mounted on the support plate.

[0007] The beneficial effects of this utility model are as follows: the coordinated use of the pay-off mechanism and the take-up mechanism realizes the automated packaging of bare fibers, which greatly improves production efficiency compared with manual packaging; by monitoring the changes in fiber tension, the pay-off and take-up speeds are kept consistent to avoid fiber breakage or tearing, and the packaging process can be automatically metered, which effectively improves the packaging quality.

[0010] The beneficial effects of this improvement are: the servo motor can drive the pay-off shaft to rotate stably through the synchronous belt transmission mechanism, so that the pay-off shaft can drive the bare fiber reel to rotate stably and synchronously under the cooperation of the locking part and the quick lock head of the optical rod.

[0011] To ensure the synchronization of the rotation of the bare fiber spool and the pay-off shaft;

[0012] As a further improvement to the above technical solution: the locking component includes an open fixing ring and a plug plate.

The plug plate has a channel steel structure, and the two flanges of the plug plate are adapted to be inserted into the through groove of the wire clamp part of the bare fiber spool.

[0013] The beneficial effects of this improvement are as follows: while the locking component works with the quick-lock head of the optical rod to axially limit the movement of a pair of bare fiber reels, the plug plate in the locking component can be inserted into the bare fiber reel to limit the movement of the bare fiber reel in the circumferential direction, ensuring that the bare fiber reel rotates stably with the feed shaft.

[0014] To ensure the stability of optical fiber transmission between the pay-off and take-up mechanisms;

[0015] As a further improvement to the above technical solution: a guide wheel assembly is installed on the base below the front of the guide wheel, and the guide wheel assembly includes no less than two guide wheels.

[0016] The beneficial effects of this improvement are as follows: the optical fiber can be led out from the bare fiber spool to the first winding wheel of the guide wheel assembly, then wound onto the guide wheel, then wound onto the second winding wheel of the guide wheel assembly, and then led out to the take-up mechanism, thus ensuring the stability of optical fiber transmission during the movement of the guide wheel.

[0017] In order to effectively control the speed difference between take-up and release of the wire;

[0018] As a further improvement to the above technical solution: the control module includes a transmitter and a motor driver, the tension detector and the touch screen PLC are electrically connected to the transmitter in the control module, and the motor driver in the control module is electrically connected to the touch screen PLC and the servo drive motor of the light rod quick lock head, the reciprocating screw, and the servo motor.

[0019] The beneficial effects of this improvement are: through real-time feedback from the tension detector, the control module can adjust the motor speed according to the precise angle information, ensuring that the speed difference between take-up and release is within a small range, thus avoiding damage to the optical fiber.

[0020] To ensure the stability of the slider's movement;

[0021] As a further improvement to the above technical solution: a bracket is installed on the reciprocating screw, and the linear guide is installed on the top surface of the bracket.

[0022] The beneficial effects of this improvement are: the bracket supports the linear guide rail and ensures the stability of the slider movement.

[0023] To ensure that the optical fiber is stably drawn onto the take-up roller;

[0024] As a further improvement to the above technical solution: multiple guide wheels are mounted on the support plate, and guide wheels are mounted on the encoder shaft.

[0025] The beneficial effects of this improvement are: with the traction support of multiple guide rollers, the optical fiber can be stably led out through the guide nozzle to the take-up roller for winding.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0035] Example 1:

[0036] like Figure 1As shown in Figure 6: A dedicated fiber optic cable laying and take-up device includes a cable laying mechanism 1 and a take-up mechanism 2. Both the cable laying mechanism 1 and the take-up mechanism 2 include a base 3 and a frame 4. The frame 4 is mounted on the base 3. A servo motor 5 is mounted on the frame 4 of the cable laying mechanism 1, and a cable laying shaft 7 and a rotating rod 11 are rotatably mounted thereon. The servo motor 5 is connected to the cable laying shaft 7 via a synchronous belt transmission mechanism 6. A locking component 9, a bare fiber reel 8, and a quick-lock head 10 for the optical fiber rod are sequentially mounted on the cable laying shaft 7. The rotating rod 11 connects one end of a front rod 12 and a rear rod 13. A guide wheel 14 is mounted on the other end of the front rod 12, and a pull rope 15 is wound around and connected to the other end of the rear rod 13. The pull rope 15 is wound around and connected to one end of a rotating plate 18, and the other end of the rotating plate 18 is connected to a tension detector 16. The tension detector 16 is mounted on the base 3. The frame 4 of the take-up mechanism 2 is equipped with a linear guide rail 27, a touch screen PLC 19, a control module 20, and a take-up shaft 21 and a reciprocating screw 24. The drive motors of the take-up shaft 21 and the reciprocating screw 24 are fixed on the frame 4. The take-up shaft 21 is slidably fitted with a take-up roller 22, and the take-up shaft 21 on both sides of the take-up roller 22 is equipped with a light rod quick lock head 23. The reciprocating screw 24 is threadedly connected to a slider 26. The slider 26 is slidably connected to the linear guide rail 27, and a support plate 29 is mounted on the slider 26. An encoder 30 and a wire nozzle 31 are mounted on the support plate 29. The automatic sorting of bare fibers is achieved through the cooperation of the pay-off mechanism 1 and the take-up mechanism 2, which greatly improves production efficiency compared with manual sorting.By monitoring changes in fiber tension, consistent take-up and feed speeds are maintained to prevent fiber breakage or tearing. Furthermore, the packing process can be automatically metered, effectively improving packing quality. The driving and driven pulleys in the synchronous belt drive mechanism 6 are respectively mounted on the output shaft of the servo motor 5 and the feed shaft 7. The locking element 9 and the quick-lock head 10 of the optical rod are respectively abutted against the two end faces of the bare fiber reel 8. The servo motor 5 can drive the feed shaft 7 to rotate stably via the synchronous belt drive mechanism 6, causing the feed shaft 7 to drive the bare fiber reel 8 to rotate stably and synchronously under the cooperation of the locking element 9 and the quick-lock head 10. The locking element 9 includes an open fixing ring 91 and a plug-in... Plate 92, the open fixing ring 91 is adapted to be clamped on the pay-off shaft 7, the plug plate 92 is fixed at one end of the open fixing ring 91, the plug plate 92 has a channel steel structure, and the two flanges of the plug plate 92 are adapted to be inserted into the through groove of the wire clamp part of the bare fiber spool 8. The locking member 9, while cooperating with the quick lock head 10 of the optical rod to limit the axial movement of the bare fiber spool 8, can also insert the plug plate 92 in the locking member 9 onto the bare fiber spool 8 to limit the circumferential movement of the bare fiber spool 8, ensuring that the bare fiber spool 8 rotates stably with the pay-off shaft 7. A guide wheel assembly 17 is installed on the base 3 below the front of the guide wheel 14. The guide wheel assembly 17 includes no less than two The optical fiber can be led from the bare fiber reel 8 to the first winding wheel of the guide wheel assembly 17, then wound onto the guide wheel 14, then onto the second winding wheel of the guide wheel assembly 17, and finally led to the take-up mechanism 2. This ensures the stability of the optical fiber delivery during the movement of the guide wheel 14. The control module 20 includes a transmitter and a motor driver. The tension detector 16 and the touch screen PLC 19 are electrically connected to the transmitter in the control module 20. The motor driver in the control module 20 is electrically connected to the touch screen PLC 19 and the servo drive motor of the optical rod quick lock head 23 and the reciprocating screw 24. The servo motor 5, through real-time feedback from the tension detector 16, allows the control module 20 to adjust the motor speed based on precise angle information, ensuring that the speed difference between take-up and untake-up is within a small range and preventing damage to the optical fiber. A bracket 28 is mounted on the reciprocating screw 24, and the linear guide rail 27 is mounted on the top surface of the bracket 28. The bracket 28 supports the linear guide rail 27, ensuring the stability of the slider 26's movement. Multiple guide rollers are mounted on the support plate 29, and guide rollers are mounted on the encoder 30's shaft. Through the traction and support of these multiple guide rollers, the optical fiber can be stably led out through the guide nozzle 31 to the take-up roller 22 for winding.

[0037] The working principle of this technical solution is as follows: First, the bare fiber spool 8 is installed on the pay-off shaft 7 of the pay-off mechanism 1. The locking member 9 and the quick-lock head 10 of the guide rod are respectively attached to the two end faces of the bare fiber spool 8. The open fixing ring 91 in the locking member 9 is adapted to clamp on the pay-off shaft 7. The two flanges of the plug plate 92 are inserted into the through groove of the wire clamp part of the bare fiber spool 8 to achieve axial and circumferential limiting of the bare fiber spool 8, ensuring that the bare fiber spool 8 rotates synchronously with the pay-off shaft 7. At the same time, the take-up roller 22 is slidably fitted onto the take-up shaft 21 of the take-up mechanism 2 and fixed in a suitable position by the quick-lock head 23 of the guide rod. The servo motor is started. The drive motors of the take-up shaft 21 and the reciprocating screw 24 are servo motor 5. The output shaft of servo motor 5 drives the pay-off shaft 7 to rotate stably through the synchronous belt transmission mechanism 6. The pay-off shaft 7 drives the bare fiber reel 8 to rotate synchronously to start pay-off. After the optical fiber is led out from the bare fiber reel 8, it is first led to the first guide wheel of the guide wheel assembly 17, then wound upward to the guide wheel 14, and then wound downward to the second guide wheel of the guide wheel assembly 17. The guide wheel assembly 17 consists of no less than two guide wheels, which can ensure the stability of optical fiber delivery during the movement of the guide wheel 14. When the optical fiber tension changes, it will drive the guide wheel 14 to move, thereby changing the tension. The tension of rope 15 causes the rotating plate 18 to rotate. Tension detector 16 detects this change and transmits a signal to the transmitter in control module 20. Control module 20 includes a transmitter and a motor driver. The transmitter processes the signal and transmits it to touchscreen PLC 19. Touchscreen PLC 19 analyzes and processes the signal according to a preset program, and then adjusts the servo drive motor speeds of servo motor 5, take-up roller 22, and reciprocating screw 24 in take-up mechanism 2 via the motor driver to ensure consistent take-up and untake-up speeds and prevent the optical fiber from breaking or snapping due to abnormal tension. The optical fiber is introduced into take-up mechanism 2, and the drive motor of take-up roller 22... The motor drives the take-up roller 22 to rotate for take-up. At the same time, the servo drive motor of the reciprocating screw 24 drives the reciprocating screw 24 to rotate. The slider 26, which is threaded to the reciprocating screw 24, moves back and forth on the linear guide rail 27. The linear guide rail 27 is installed on the top surface of the bracket 28, which provides support and ensures the stability of the slider 26. The support plate 29 installed on the slider 26 moves accordingly. The optical fiber is stably led out through the guide nozzle 31 to the take-up roller 22 for winding after being pulled and supported by multiple guide wheels. The encoder 30 can monitor the winding length of the optical fiber in real time, realize the automatic meter counting function, and ensure the packaging quality.
