Abstract
Description
Technical Field
[0001] This invention relates to a shuttle traction device and its application in optical fiber take-up equipment, belonging to the field of automated optical fiber production and packaging technology. Background Technology
[0002] Plastic optical fiber is a common type of optical fiber and is widely used in daily life. Existing plastic optical fibers are usually manufactured using a roll-to-roll take-up method.
[0003] At the start of the fiber optic take-up process, manual operation is required to pull and fix the fiber head to the starting position of the take-up reel. After each take-up reel is wound and the fiber is cut, manual operation is necessary to repeatedly pull the fiber to the next empty take-up reel. This process is characterized by low automation and high labor intensity. Furthermore, when manually pulling the fiber into the take-up equipment, it is easy to bump into the already aligned winding mechanism, causing a change in the position of the already aligned mechanism and affecting the accuracy of the take-up. If a fiber breaks during the take-up process, the previously taut fiber instantly loses its winding force and unwinds, requiring manual rewinding and reorganization, which is detrimental to the automated production of fiber optic take-up equipment.
[0004] Furthermore, due to the limited maximum tensile stress that optical fibers can withstand, most existing fiber winding equipment uses a basic tensioning device during the winding process. This makes it difficult to simultaneously ensure a constant tension on the fiber and the tightness of the winding, easily damaging the tight structure of the fiber winding and even causing fiber breakage, seriously affecting the quality of optical fiber production. Moreover, existing fiber winding equipment cannot adjust for the different requirements of various new types of optical fibers for stability, tension, and transmission speed, resulting in batch production defects and incompatibility issues, severely impacting the efficiency of optical fiber winding production. Summary of the Invention
[0005] The technical problem solved by this invention is to address the issues of high labor intensity and low automation of manual traction in existing optical fiber take-up equipment, and to provide a shuttle traction device and its application in optical fiber take-up equipment.
[0006] This invention is achieved using the following technical solution:
[0007] A shuttle traction device includes a set of anti-reverse rollers that clamp the transmitted optical fiber and a shuttle that pulls the optical fiber through the anti-reverse rollers. The anti-reverse roller set includes a fixed anti-reverse roller and a moving anti-reverse roller that clamp the optical fiber by rollers. The moving anti-reverse roller is movably arranged relative to the fixed anti-reverse roller and is pressed against the fixed anti-reverse roller by an elastic connector. At least one set of the fixed anti-reverse roller and the moving anti-reverse roller is unidirectionally locked in the opposite direction of optical fiber traction. The shuttle is moved along the traction direction of the optical fiber, and its initial position is in the reverse direction. On the fiber optic inlet side of the stop wheel assembly, there is a finger unit that clamps the fiber optic cable. Between the shuttle and the reverse stop wheel, there is a first cam assembly that pushes the reverse stop wheel relative to the reverse stop wheel as the shuttle moves through the reverse stop wheel assembly. The first cam assembly separates the reverse stop wheel and the reverse stop wheel by the movement of the shuttle, so that the finger assembly of the shuttle clamps the fiber optic cable and passes it through the reverse stop wheel and the reverse stop wheel. After the shuttle moves, the reverse stop wheel returns to its original position under the action of its connected elastic connector, clamping the fiber optic cable that has been pulled through.
[0008] In the shuttle traction device of the present invention, the finger unit is further provided on the shuttle via an elastic connector and moves in the same direction as the reverse stop wheel. A second cam group is provided between the fixed position of the finger unit and the reverse stop wheel group, which pushes the finger unit and the reverse stop wheel synchronously during the shuttle moving through the reverse stop wheel group. The second cam group moves the finger unit towards the reverse stop wheel side while the shuttle moves, so as to avoid interference and collision between the finger unit and the reverse stop wheel during the movement of the finger unit along the optical fiber traction direction.
[0009] In the shuttle traction device of the present invention, the finger unit is further provided with a telescopic drive component that avoids the anti-reverse wheel group when the shuttle moves back to the initial position. During the process of returning to the initial position, the finger unit does not pass through the anti-reverse wheel group in the opposite direction, but is driven by the telescopic drive component to retract and avoid the anti-reverse wheel group. After the shuttle returns to the position, the finger unit is extended to the initial position.
[0010] In the shuttle traction device of the present invention, the fixed backstop wheel and the moving backstop wheel of the backstop wheel group are mounted on the yarn output assembly support plate. The yarn output assembly support plate is provided with a shuttle traction groove through which the finger unit of the shuttle passes. The fixed backstop wheel is set on one side of the shuttle traction groove by a one-way locking backstop shaft. The moving backstop wheel is slidably set on the other side of the shuttle traction groove by a moving backstop wheel guide rail. The moving wheel return spring set on the yarn output assembly support plate presses the rollers together with the fixed backstop wheel in the shuttle traction groove.
[0011] In the shuttle traction device of the present invention, the first cam group includes a first cam follower fixedly disposed with the reverse stop wheel, and a push plate that moves with the shuttle along the optical fiber traction direction. The push plate is provided with a cam surface that contacts the first cam follower. The second cam group includes a second cam follower fixedly disposed with the finger unit, and a cam guide groove disposed on the wire feed assembly support plate. The second cam follower is embedded in the cam guide groove at the initial position of the shuttle.
[0012] This invention also discloses an optical fiber take-up device, including a punch-hole device, a take-up reel, and the aforementioned shuttle traction device. The punch-hole device includes a swing arm with a swaying arm. The swing arm is equipped with a hanging cylinder that guides the optical fiber pulled into position by the shuttle traction device onto the take-up reel. The take-up reel includes a take-up shaft, a take-up drum, a positioning guide wheel, a guide clamping plate, and a take-up linear module. The take-up shaft is connected to a power drive unit. The take-up drum is detachably mounted on the take-up shaft. The positioning guide wheel is fixedly mounted on the take-up shaft at the end of the take-up drum. The guide clamping disc and the positioning guide wheel are coaxially nested, and an elastic guide component is provided between the positioning guide wheel and the guide clamping disc to clamp each other. The take-up disc is provided with a roller assembly that separates the guide clamping disc from the positioning guide wheel. The take-up disc is slidably mounted on the take-up straight module. The wire punch moves the pulled optical fiber into position and clamps it between the separated guide clamping disc and the positioning guide wheel. The optical fiber is evenly wound onto the take-up drum through the linkage of the take-up shaft and the take-up straight module. The take-up shaft is provided with a take-up photoelectric switch to detect the number of optical fiber winding turns.
[0013] In the optical fiber take-up device of the present invention, a further step is to include a touch-controlled guide wheel assembly. The touch-controlled guide wheel assembly includes a touch-controlled reversing wheel slidably mounted between the take-up reel and the optical fiber pulled into position by the shuttle traction device. The touch-controlled reversing wheel is provided with a touch-sensitive plate that triggers a contact switch. The contact switch is connected to the take-up reel for feedback control. After the wire punch moves the pulled optical fiber around the touch-controlled reversing wheel, it is guided to the take-up reel. The optical fiber presses against the touch-controlled reversing wheel to trigger the contact switch, thereby controlling the take-up action of the take-up reel.
[0014] In the optical fiber take-up device of the present invention, the punch is further provided with a blade for cutting the optical fiber after the take-up is completed. After the take-up spool on the take-up reel has finished winding the optical fiber, the punch moves the optical fiber to the blade on the punch to cut the optical fiber, so as to facilitate the removal of the finished take-up spool from the take-up reel.
[0015] In the optical fiber take-up device of the present invention, the take-up device further includes two sets of take-up reels. The shuttle traction device pulls the optical fiber between the two sets of take-up reels. The clamping gaps between the positioning guide wheel and the guide clamping plate of the two sets of take-up reels are located side by side on both sides of the optical fiber that has been pulled into position. The punch is set on the switching linear module that moves the hanging cylinder on the swing arm to the left and right sides of the optical fiber. The punch guide moves the optical fiber from both sides of the optical fiber to the two sets of take-up reels respectively. It also includes two sets of touch guide wheels arranged side by side. The two sets of touch guide wheels are respectively set between the two sets of take-up reels and the optical fiber that has been pulled into position. The shuttle traction device pulls the optical fiber through the two sets of touch guide wheels. The punch guide moves the optical fiber pulled by the shuttle traction device to the take-up drums on both sides of the take-up reels for winding. During the winding process of one take-up reel, the take-up drums of the other take-up reel can be picked up and put on, which improves the continuous winding production efficiency of optical fiber.
[0016] In the optical fiber take-up device of the present invention, a further included feed wheel assembly is provided. The feed wheel assembly is located on the feed side of the anti-reverse wheel assembly of the shuttle traction device and has a storage wheel assembly with adjustable wheel spacing. The storage wheel assembly includes a fixed storage wheel and a sliding storage wheel that slides relative to the fixed storage wheel. The optical fiber entering the take-up device is wound back and forth between the fixed storage wheel and the sliding storage wheel and then pulled to the shuttle traction device. The sliding storage wheel is connected to a tension system, which includes a tension adjustment drive unit, a cable, and a tension sensor. The tension adjustment drive unit is connected to the sliding end of the sliding storage wheel through the cable. During take-up, the traction force of the optical fiber wound between the fixed storage wheel and the sliding storage wheel tightens the cable. The cable is equipped with a tension sensor that detects the traction force of the optical fiber. The tension sensor is connected to the tension adjustment drive unit for feedback. The tension sensor detects the traction force of the optical fiber between the storage wheel assemblies, and the tension adjustment drive unit adjusts the wheel spacing between the sliding storage wheel and the fixed storage wheel to adapt to different optical fiber traction forces.
[0017] The present invention, by adopting the above technical solution, has the following beneficial effects:
[0018] The shuttle traction device of the present invention uses a shuttle and a backstop wheel assembly to pull the optical fiber take-up. The shuttle can clamp the optical fiber from the initial position and automatically pass through the backstop wheel assembly to pull the optical fiber to the take-up mechanism. The backstop wheel assembly can lock and clamp the optical fiber in one direction while ensuring normal transmission during the optical fiber winding process, preventing the optical fiber from breaking during winding or losing traction force after winding and cutting. At the beginning of the winding work, it is only necessary to manually pull the end of the optical fiber to the finger unit of the shuttle to clamp it, so as to realize the automated traction of the optical fiber to the take-up mechanism.
[0019] The shuttle traction device of the present invention can also achieve repeated automatic traction through the shuttle. After the optical fiber is wound and cut, the shuttle can return to the initial position to re-clamp the optical fiber for automatic traction, reducing the manual repeated traction operation in the continuous optical fiber winding production process.
[0020] In the shuttle traction device of the present invention, the reverse stop moving wheel of the reverse stop wheel group is set with the reverse stop fixed wheel through an elastic connector to press the rollers together. It can adapt to the traction and clamping of optical fibers with different cross-sectional sizes, ensure the stable guidance and instant braking of the optical fiber in high-speed movement, reduce the damage to the optical fiber caused by motion inertia, improve the stability of optical fiber transmission performance, and at the same time adapt to the uniform and stable traction and winding of optical fibers of different sizes, thus improving the versatility and adaptability of the winding equipment.
[0021] The shuttle traction device of the present invention can also maintain the clamping of the incoming optical fiber by means of the anti-reverse wheel group after the wire breaks during the take-up process, and then the shuttle quickly responds and returns to the initial position to automatically perform the wiring operation without manual intervention, thus enabling continuous operation without stopping the machine.
[0022] The fiber optic take-up device of the present invention, based on the shuttle traction device, uses a wire punch and a touch-controlled guide wheel group to realize fully automatic take-up of the fiber optic cable after traction. The fiber optic take-up device can be equipped with two sets of take-up reels for alternating take-up in sequence. At the same time, the wire punch can automatically cut the fiber optic cable after take-up. During the process of one set of take-up reels winding the fiber, the take-up reel of the other set of take-up reels can be picked up and put on, which improves the automation and take-up efficiency of continuous fiber optic take-up production.
[0023] The fiber optic take-up device of this invention employs an automatically tension-adjustable feed roller assembly. The feed roller assembly stores optical fibers through a storage roller assembly. When the fiber winding production rate changes, the amount of stored optical fiber can be adjusted by changing the roller spacing of the storage roller assembly based on the signal from the tension sensor. This ensures that the subsequent take-up speed is not affected by the previous production rate. At the same time, the feed roller assembly can monitor the fiber traction tension in real time during the take-up process and dynamically adjust the tension of the feed roller assembly on the optical fiber. It can automatically adjust to the optimal tension range based on parameters such as fiber material and diameter, effectively avoiding damage to the optical fiber caused by excessive stress and ensuring the quality of the optical fiber and the tightness of the take-up coil.
[0024] In summary, the shuttle traction device and the optical fiber take-up equipment disclosed in this invention can realize automatic traction in the optical fiber take-up process, achieve automated optical fiber take-up production, reduce manual traction in the take-up process, and improve the production efficiency of automatic optical fiber take-up.

[0053] Example 1
[0054] See Figure 1 The figure shows a specific embodiment of the optical fiber take-up device of the present invention. The embodiment includes the shuttle traction device of the present invention to automatically traction the optical fiber being taken up. The shuttle traction device will be described in detail below through this embodiment.
[0055] like Figure 1 As shown, the shuttle traction device of the optical fiber take-up equipment includes two parts: a backstop wheel group 3 and a shuttle 4. The optical fiber 9 enters the backstop wheel group 3 from the lead wire 302 above the backstop wheel group 3. The shuttle 4 clamps the optical fiber 9 and pulls it through the backstop wheel group 3 to the inside of the take-up equipment below.
[0056] like Figure 2 , Figure 3 and Figure 4As shown, the structure of the backstop wheel assembly 3 is mounted on the wire feed assembly support plate 301. The backstop fixed wheel and backstop moving wheel of the backstop wheel assembly 3 are mounted on the wire feed assembly plate 301 as components of the backstop fixed wheel assembly 304 and the backstop moving wheel assembly 305, respectively. The wire feed guide wheel 302 is mounted on the upper half of the wire feed assembly support plate 301 by screws. A shuttle traction groove 307 is provided in the lower half of the wire feed assembly support plate 301. The backstop fixed wheel assembly 304 and the backstop moving wheel assembly... 305 is installed on the wire output assembly support plate 301 on the left and right sides of the shuttle traction groove 307. A wire guide rod 303 is threadedly connected to the wire output assembly support plate 301 between the wire output guide wheel 302 and the shuttle traction groove 307. A cam guide groove 306 is fixed on the back of the wire output assembly support plate 301 of the reverse stop wheel assembly 305, which serves as the second cam group active member that pushes the shuttle finger unit to avoid the reverse stop wheel in the fixed position of the reverse stop wheel group.
[0057] Specifically, in the backstop wheel assembly 3, both the fixed backstop wheel and the moving backstop wheel are mounted on the wire feed assembly support plate 301 using a component structure. The fixed backstop wheel assembly 304 includes a fixed wheel roller 3041, a backstop shaft 3042, a drum seat 3043, a ratchet fixing seat 3044, a ratchet 3045, a coupling 3046, an encoder 3047, and an encoder fixing plate 3048. The fixed backstop wheel assembly 305 is mounted on the wire feed assembly support plate 301 via the drum seat 3043. The ratchet fixing seat 3044 is fixedly mounted to the rear end of the drum seat with screws. The ratchet fixing seat 3044 and the encoder fixing plate 3048 are coaxially fixed together using studs. The backstop shaft 3044... 42 passes through the support plate 301 of the wire feeding assembly from the barrel 3043 and is rotatably assembled with the barrel 3043. The fixed roller 3041 and the ratchet 3045 are fixedly installed on the backstop shaft 3042 in sequence. The shaft end of the backstop shaft 3042 is connected to the encoder 3047 through the coupling 3046. The fixed roller 3041 serves as the backstop fixed roller body of the backstop wheel group and is paired with the backstop moving roller. The ratchet 3045 cooperates with the pawl on the ratchet fixing seat 3044 to realize the one-way locking of the backstop shaft 3042. The encoder 3047 cooperates with the encoder fixing seat 3044 to monitor the number of rotations of the backstop wheel group to obtain the fiber length data of the traction through the backstop wheel group.
[0058] The reverse stop wheel assembly 305 includes a moving wheel roller 3051, a wall plate 3052, a retraction plate 3053, a fixing block 3054, a moving wheel guide rail 3055, a moving wheel return spring 3056, a clamping adjustment column 3057, an adjustment baffle 3058, and a first cam follower 3059. The moving wheel roller 3051 is mounted on one end of the wall plate 3052 via a roller shaft, and the other end of the wall plate 3052 is mounted on the fixing block 3054. A portion of the fixing block 3054 is slidably assembled with the moving wheel guide rail 3055. The moving wheel guide rail 3055 is horizontally mounted on the wire exit side of the shuttle traction groove. On the assembly support plate 301, the fixed block 3054 can drive the moving wheel roller 3051 and the wall plate 3052 to slide relative to the anti-reverse fixed wheel assembly on the moving wheel guide rail 3055. The fixed block 3054 is connected to the pressure adjustment column 3057. The moving wheel return spring 3056 is sleeved on the pressure adjustment column 3057. One end of the moving wheel return spring 3056 contacts the fixed block, and the other end contacts the adjustment baffle 3058. The adjustment baffle 3058 is sleeved on the pressure adjustment column 3057 and limited by the nut. At the same time, the adjustment baffle 3058 is fixed to the wire outlet assembly support plate 301 by screws. The axial direction of the clamping adjustment column 3057 and the moving wheel return spring 3056 is parallel to the moving wheel guide rail 3055. The moving wheel return spring 3056, as an elastic connecting member of the reverse stop moving wheel, presses the moving wheel roller against the fixed wheel roller on the other side of the shuttle traction groove. The compression distance of the moving wheel return spring 3056 between the fixed block and the adjusting baffle can be adjusted by the nut screwed on the clamping adjustment column outside the adjusting baffle 3058, thereby realizing the clamping force of the moving wheel roller on the fixed wheel roller. The fixed block 3054 is connected to the retraction plate 3053 below, which is used to manually move the moving wheel roller and the fixed wheel roller apart. The retraction plate 3053 extends to the rear end of the wire feeding assembly support plate 301, and the first cam follower 3059 is connected behind the retraction plate 301. The first cam group follower is driven by the shuttle to push the reverse stop moving wheel.
[0059] Both the fixed roller 3041 and the moving roller 3051 are made of rubber, which has a certain elasticity to protect the optical fiber that is pressed between them and can provide sufficient friction for clamping the optical fiber. The fixed roller 3041 is a side guard roller, which can prevent the optical fiber from deviating and coming off the clamp of the anti-reverse roller group during the transmission process.
[0060] like Figure 5 , Figure 6 and Figure 7As shown, the shuttle 4 includes a shuttle base plate 401, a shuttle rodless cylinder 402, a cylinder base plate 403, a push plate 404, a linear guide rail 405, and a finger unit 406. All components of the shuttle 4 are connected together via the shuttle base plate 401. Specifically, the shuttle base plate 401 is connected to the slider of the shuttle rodless cylinder 402 by screws. The shuttle rodless cylinder 402 is fixedly mounted on the frame of the optical fiber take-up device via two cylinder base plates 403, used to fix the entire shuttle 4. The push plate 404 is connected to the shuttle base plate 401. The push plate 404 has a cam surface that contacts the first cam follower 3059. The push plate 404 acts as the driving component for pushing the first cam group of the reverse stop wheel during shuttle movement, and cooperates with the first cam follower 3059 of the reverse stop wheel assembly 305 to form the first cam group. A linear guide rail 405 is mounted on the upper surface of the shuttle base plate 401. The finger unit 406 is movably mounted on the shuttle base plate 401 via the linear guide rail 405. The finger unit 406 moves left and right along the linear guide rail 405 to move and avoid the fixed roller during the shuttle's movement through the anti-reverse wheel group. The finger unit 406 is connected to the shuttle base plate 401 below via a finger return spring 4051 to ensure that the finger unit 406 is always at the leftmost position of the linear guide rail when there is no external force.
[0061] The finger unit 406 specifically includes a movable plate 4061, a finger-clamping cylinder base plate 4062, a finger clamp 4063, a finger-clamping cylinder 4064, a second cam follower 4065, a follower seat 4066, a finger telescopic guide rail 4067, a cylinder mounting seat 4068, and a finger telescopic cylinder 4069. The finger unit 406 is slidably assembled with the linear guide rail 405 on the shuttle base plate 401 via the movable plate 4061. The finger telescopic guide rail 4067 is longitudinally mounted on the movable plate 4061. The finger-clamping cylinder base plate 4062 is connected above the guide rail slider of the finger telescopic guide rail 4067. The finger clamp 4063, driven by the finger clamping cylinder 4064, is provided on the finger clamping cylinder base plate 4062 for clamping the optical fiber by the finger unit. The finger telescopic cylinder 4069 is fixed to the moving plate 4061 via the cylinder mounting seat 4068. The telescopic direction of the finger telescopic cylinder 4069 is parallel to the finger telescopic guide rail 4067. The air rod of the finger telescopic cylinder 4069 is connected to the base plate 4062 of the finger clamping cylinder. The finger telescopic cylinder 4069 pushes the base plate of the finger clamping cylinder and the finger clamping on it to move longitudinally, avoiding the anti-reverse wheel group when the shuttle moves back to the initial position of clamping the optical fiber. A second cam follower 4065 is set at the front end of the moving plate 4061 via the follower seat 4066. The second cam follower 4065 acts as a cam follower that pushes the finger unit to move and avoid the anti-reverse wheel group during the process of the shuttle pulling the optical fiber through the anti-reverse wheel group. When the shuttle moves to the initial position of clamping the optical fiber, it is embedded in the cam guide groove 306 provided on the back of the fiber output assembly support plate 301 of the anti-reverse wheel assembly 305, forming the second cam group.
[0062] Pneumatic gripper is a mature industrial picking robot technology, and the specific structure of the gripper will not be described in detail in this embodiment.
[0063] In the shuttle traction device of this embodiment, the anti-reverse wheel group 3 clamps the optical fiber 9 through a fixed roller 3041 and a moving roller 3051 arranged in a roller configuration. Simultaneously, the rolling motion of the fixed roller 3041 and the moving roller 3051 adapts to the transmission of the optical fiber during the take-up process. The moving roller 3051 is movably arranged relative to the fixed roller 3041 and is pressed against the fixed roller 3041 by a moving roller return spring 3056. The fixed roller 3041 is unidirectionally locked in the opposite direction of optical fiber traction via a ratchet mechanism.
[0064] The shuttle 4 clamps the optical fiber 9 through the finger unit and moves along the traction direction of the optical fiber through the fixed roller 3041 and the moving roller 3051 of the anti-stop wheel group 3. The initial position of the shuttle 4 clamping the optical fiber is located on the optical fiber inlet side of the anti-stop wheel group 3. Between the shuttle 4 and the anti-stop moving wheel assembly 305, there is a first cam group that pushes the anti-stop moving wheel relative to the anti-stop fixed wheel when the shuttle moves through the anti-stop wheel group. The first cam group includes a push plate 404 provided on the bottom plate of the shuttle and a first cam follower 3059 in the anti-stop wheel assembly.
[0065] Specifically, after the finger unit 406 of the shuttle 4 clamps the optical fiber 9 from its initial position, it moves along the traction direction of the optical fiber 9 from the inlet side of the anti-reverse roller group 3 through the anti-reverse roller group 3 to the other side. During this process, the shuttle 4 pushes open the moving roller 3051 of the anti-reverse roller group 3 through the first cam group. The finger unit 406 of the shuttle 4, holding the optical fiber, passes between the separated fixed roller 3041 and moving roller 3051, pulling the optical fiber 9 to the take-up mechanism inside the take-up device. After the shuttle 4 passes the rear anti-reverse roller group, the moving roller 3051 returns to its original position under the action of the moving roller return spring 3056 and re-presses the rollers with the fixed roller 3041, clamping the optical fiber 9 pulled through by the shuttle. The fixed roller 3041 and the moving roller 3051 of the anti-reverse wheel assembly 3 are clamped together, and the relative clamping between the fixed roller 3041 and the moving roller 3051 clamps the optical fiber 9. At the same time, the clamping between the fixed roller 3041 and the moving roller 3051 does not affect the normal transport of the optical fiber 9 between the fixed roller 3041 and the moving roller 3051. Furthermore, the fixed roller 3041 of the anti-reverse wheel assembly is unidirectionally locked in the opposite direction of optical fiber traction through a ratchet mechanism. That is, the fixed roller 3041 and the moving roller 3051 of the anti-reverse wheel assembly 3 can only transport the optical fiber in the direction of optical fiber traction. After the winding mechanism loses its traction force on the optical fiber, the clamped fixed roller 3041 and the moving roller 3051 will not transport the optical fiber in the opposite direction of optical fiber traction. In this way, the optical fiber 9 is clamped by the anti-reverse wheel assembly, maintaining the traction force of the optical fiber on the fiber feeding side of the anti-reverse wheel assembly. In practical applications, other shaft-mounted one-way transmission mechanisms, such as overrunning clutches or one-way bearings, can also be used to achieve one-way locking.
[0066] The shuttle 4 moves along the traction direction of the optical fiber 9, pulling the optical fiber 9 to the subsequent take-up mechanism. The "traction direction" referred to here is the direction in which the optical fiber is conveyed through the anti-reverse wheel group 3, and should not be understood as the overall traction direction during the optical fiber take-up process. The initial position of the shuttle 4 is located on one side of the anti-reverse wheel group 3. In actual use, it is only necessary to manually pull the end of the optical fiber forward to clamp it on the shuttle finger unit 406 located in the initial position, and the shuttle 4 will automatically pull the optical fiber through the anti-reverse wheel group 3 and pull it to the subsequent take-up mechanism.
[0067] When the finger unit 406 moves with the shuttle 4 through the anti-reverse wheel assembly, the moving wheel roller 3051 of the anti-reverse wheel assembly 305 has been pushed away by the first cam assembly. To further avoid interference and collision between the finger unit 406 and the fixed wheel roller 3041 of the fixed anti-reverse wheel assembly 304, in this embodiment, the finger unit 406 is movably mounted on the shuttle 4 via an elastic connector, and the finger unit 406 has the same direction of movement as the moving wheel roller 3051. Specifically, the finger unit 406 is slidably mounted on the transverse base plate 401 of the shuttle via a linear guide rail 405. The linear guide rail 405 is parallel to the anti-reverse wheel guide rail 3055 of the anti-reverse wheel assembly 305. A finger return spring 4051 is provided between the transverse base plates 401, and the elastic force of the finger return spring 4051 positions the finger unit 406 in its initial position. A second cam group is provided between the finger unit 406 and the fixed position of the anti-optical wheel group 3. The second cam group includes a second cam follower 4065 on the finger unit 406 and a cam guide groove 306 fixedly provided on the wire feed assembly support plate 301 of the anti-optical wheel group. After the shuttle moves to the initial position of clamping the optical fiber, the second cam follower 4065 is embedded in the cam guide groove 306. After the finger unit 406 moves with the shuttle, the cam surface in the cam guide groove 306 pushes the finger unit 406 together with the second cam follower and the moving wheel roller 3051 to move and avoid the fixed wheel roller. After the finger unit 406 passes through the anti-optical wheel group, the second cam follower 4065 disengages from the cam guide groove 306. Under the action of the finger return spring 4051, the finger unit 406 returns to the initial position laterally and continues to move along the optical fiber traction direction.
[0068] To avoid interference and collision between the finger unit and the moving wheel roller after the finger unit moves to avoid the collision, the cam stroke of the second cam group that pushes the finger unit to avoid the collision should be less than the cam stroke of the first cam group that pushes the moving wheel roller.
[0069] During the process of the shuttle 4 retracting to re-clamp the optical fiber from its initial position, the shuttle 4 does not pass through the anti-reverse wheel group 3 along the traction route. Instead, it avoids the anti-reverse wheel group by using a telescopic drive assembly on the shuttle that drives the finger unit 406 to move longitudinally. In this embodiment, the telescopic drive assembly that drives the finger unit 406 to extend and retract to avoid the anti-reverse wheel group includes a finger telescopic guide rail 4067 and a finger telescopic cylinder 4069. The finger telescopic cylinder 4069 is actively controlled. During the process of the shuttle driving the finger unit to pull the optical fiber, the finger telescopic cylinder 4069 does not move, keeping the finger unit 406 moving along the optical fiber traction route. When the shuttle drives the finger unit back to its initial position, the finger telescopic cylinder 4069 retracts the finger unit 406 a certain distance along the finger telescopic guide rail 4067 to avoid the anti-reverse wheel group. After the finger unit returns to the initial position height with the shuttle, the finger telescopic cylinder 4069 extends the finger unit 406 again, completely retracting the finger unit 406 back to the initial position of clamping the optical fiber.
[0070] In this embodiment, the finger telescopic guide rail 4067, the linear guide rail 405, and the shuttle rodless cylinder 402 of the shuttle form a spatial three-coordinate system in which the finger unit moves with the shuttle. The shuttle rodless cylinder 402 is arranged along the fiber optic traction direction, driving the shuttle and the finger unit on it to move along the fiber optic traction direction. The sliding directions of the linear guide rail 405 and the anti-stop wheel are parallel and perpendicular to the moving direction of the rodless cylinder 402. The finger unit 406 moves passively in this direction through the first cam group. The finger telescopic guide rail 4067 is arranged perpendicular to the moving directions of the shuttle rodless cylinder 402 and the linear guide rail 405, respectively. The finger unit 406 is driven in this direction by the finger telescopic cylinder 4069, so that the finger unit 406 avoids the anti-stop wheel group during the process of moving back to the initial position with the shuttle.
[0071] In this embodiment, the shuttle traction device uses the shuttle 4 to pull the optical fiber 9 through the anti-reverse wheel group 3. The anti-reverse wheel group 3 clamps the optical fiber and transmits it unidirectionally along the fiber take-up traction direction, ensuring the reliability of subsequent fiber take-up production traction of the optical fiber take-up equipment.
[0072] Example 2
[0073] See Figure 8 , Figure 9 and Figure 10 This embodiment, based on Embodiment 1, further elaborates on the optical fiber take-up device applying the shuttle traction device of Embodiment 1. The optical fiber take-up device also includes at least a punch-hole device 5 and a take-up reel 7. The shuttle traction device, punch-hole device 5, and take-up reel 7 of the optical fiber take-up device are all arranged on the same frame 1, as shown below. Figure 11As shown, the frame 1 includes an upper frame 101 and a lower frame box 102. The main structures of both the upper frame 101 and the lower frame box 102 are composed of aluminum profiles and aluminum plates. The upper frame 101 and the lower frame box 102 are fixedly connected by bolts. A front window 103 is hinged to the front of the main structure of the lower frame box 102, serving as an openable door / window structure to facilitate the installation, inspection, and maintenance of components inside the frame, as well as the loading and unloading of the take-up drum on the take-up reel. The bottom of the lower frame box 102 is equipped with casters 104 with supporting feet.
[0074] The specific structure of the wire punch 5 in this embodiment is as follows: Figure 12 and Figure 13 As shown, the wire punch 5 includes a module base plate 501, a switching linear module 502, a wire punch L-shaped plate 503, a cutting cylinder mounting plate 504, a cutting cylinder 505, a blade 506, a swing power mounting base plate 507, a reducer 508, a wire punch motor 509, a positioning sleeve 5010, a swing arm 5011, a hanging cylinder 5012, and a knife holder 5013. The main structure of the wire punch 5 is mounted on the switching linear module 502. The switching linear module 502 is mounted in the center of the lower end face inside the lower frame box 102 through the module base plate 501 and studs, and is arranged longitudinally. The bottom surface of the L-shaped wire-punching plate 503 is fixed to the slide of the switching linear module 502 with screws. The cutting cylinder mounting plate 504 is installed parallel to the bottom surface of the L-shaped wire-punching plate 503 with screws. The cutting cylinder 505 is fixed on the cutting cylinder mounting plate 504. The air rod of the cutting cylinder 505 is connected to the blade 506. The swing power mounting base plate 507 is installed parallel to the vertical surface of the L-shaped wire-punching plate 503 with screws. The tool holder 5013 is installed on top of the swing power mounting base plate 507 with screws. The left end of the swing power mounting base plate 507 is connected to the mounting surface of the reducer 508. The left end of the reducer 508 is connected to the wire-punching motor 509. The output shaft of the reducer 508 is connected to the positioning sleeve 5010. The lower part of the swing arm 5011 is connected to the positioning sleeve 5010 with screws. The hanging cylinder 5012 is installed on the swing end above the swing arm 5011 with pins.
[0075] The punch-hole device 5 has a swing arm 5011 with a swinging configuration. The swing arm 5011 is driven to swing back and forth by the punch-hole device motor 509 and the reducer 508. The hanging cylinder 5012 on the swing arm 5011 guides the optical fiber 9, which is pulled into place by the shuttle traction device, to the take-up reel 7. The extreme swing angles on both sides of the swing arm 5011 are enough to move the optical fiber to the knife holder 5013 on the power mounting base plate 507. At this position, the cutting cylinder 505 drives the blade 506 to cut the optical fiber.
[0076] A touch-sensitive guide wheel assembly 6 is also provided between the pulled-in optical fiber 9 and the take-up reel 7. Before the wire punch 5 moves the pulled-in optical fiber 9 to the take-up reel 7, the optical fiber passes through the touch-sensitive guide wheel assembly. The specific structure of the touch-sensitive guide wheel assembly 6 in this embodiment is as follows: Figure 14 As shown, the touch guide wheel assembly 6 includes a base plate 601, an end plate 602, a touch guide rail 603, an end stop 604, a transition block 605, a single wheel mounting shaft 606, a touch reversing wheel 607, a touch sensing plate 608, a touch wheel guide rod 609, and a contact switch 6010. The main body of the touch guide wheel assembly 6 is mounted on the base plate 601, which is screwed onto the internal frame of the lower frame box 102. An end plate 602 is provided at the end of the base plate 601 for mounting the contact switch 6010. The touch guide rail 603 is mounted on the front end face of the base plate 601. One end of the touch guide rail 603 is close to the end plate 602, and the other end is provided with an end stop 604 to limit the sliding path of the touch guide rail. A slider connected to an adapter block 605 is slidably mounted on the touch rail 603. A single wheel mounting shaft 606 is mounted on the adapter block 605. A touch reversing wheel 607 is rotatably mounted on the single wheel mounting shaft 606. A touch sensor 608 is positioned above the adapter block 605. A touch wheel guide rod 609 is fixed to an adapter seat on the side of the single wheel mounting shaft 606. The other end of the touch wheel guide rod 609 slides through a guide hole provided on the end plate 602 to assist in guiding the sliding of the touch reversing wheel 607 and the adapter block 605 along the touch rail.
[0077] The touch-sensitive guide wheel assembly 607 is slidably mounted between the take-up reel 7 and the optical fiber 9 pulled into place by the shuttle traction device via the touch-sensitive slide rail 603. The touch-sensitive guide wheel 607 is equipped with a touch-sensitive sensor 608 that moves with the touch-sensitive guide wheel. After the wire punch 5 moves the optical fiber onto the touch-sensitive guide wheel 607, the traction pressure of the optical fiber pushes the touch-sensitive guide wheel 607 to move. The touch-sensitive sensor 608 triggers the contact switch 6010. The contact switch 6010 is connected to the feedback control of the take-up reel. The take-up reel will start the take-up action normally only after receiving the feedback signal from the contact switch of the touch-sensitive guide wheel assembly.
[0078] The specific structure of the take-up reel 7 in this embodiment is as follows: Figure 15 and Figure 16As shown, the take-up reel 7 includes a take-up linear module 701, a take-up drum seat 702, a take-up seat plate 703, a take-up reducer 704, a take-up servo motor 705, a take-up drive pulley 706, a take-up transmission shaft 707, a take-up driven pulley 708, a locking nut 709, a positioning ring plate 7010, a take-up photoelectric switch 7011, a photoelectric base 7012, an adapter flange 7013, a take-up shaft 7014, a positioning guide wheel 7015, a guide clamping plate 7016, a compression spring 7017, a linear bearing 7018, a roller ring 7019, a roller follower 7020, a follower seat 7021, a slide cylinder 7022, a slide cylinder mounting base 7023, a fixed guide block 7024, and a take-up drum 7025. The main components of the take-up reel 7 are mounted on the take-up linear module 701. The take-up linear module 701 is mounted on the internal frame of the lower frame box 102 by screws, and its arrangement is consistent with the direction of the switching linear module 502 of the wire beater 5. The slider of the take-up linear module 701 is fixedly connected to the bottom of the take-up drum seat 702. The middle part of the take-up drum seat 702 is provided with a rotatable shaft mounting position. The take-up reducer 704 is connected to the take-up servo motor 705 and fixed on the take-up seat plate 703. It is installed on the take-up drum seat 702 through the mounting holes on the take-up seat plate 703. The output shaft of the take-up reducer 704 passes through the left end face of the take-up drum seat 702 and connects to the take-up drive pulley 706. The middle part of the take-up drum seat 702 is equipped with the take-up drive shaft 707. The take-up driven pulley 708, the locking nut 709, and the positioning ring plate 7010 are sequentially mounted on the shaft end of the take-up drive shaft 707 for shaft positioning and assembly of the take-up driven pulley. A take-up photoelectric switch 7011 is installed below the positioning ring plate 7010. The take-up photoelectric switch 7011 is fixed to the left end face of the take-up drum seat 702 via a photoelectric base 7012. The take-up photoelectric switch 7011 detects the rotation parameters of the take-up drive shaft. The take-up drive shaft 707 passes through the take-up drum seat 702 and is connected to the take-up shaft 7014 via an adapter flange 7013. The positioning guide wheel 7015 is fixedly mounted on one end of the take-up shaft 7014 connected to the take-up drive shaft. The guide clamping plate 7016 is coaxially embedded with the positioning guide wheel 7015. The guide clamping plate 7016 and the positioning guide wheel 7015 are connected by four sets of compression springs 7017 and four sets of linear bearings 7018 in the circumferential direction. A roller ring 7019 is coaxially fixed on the outer side of the guide clamping plate 7016, forming a roller ring groove with the guide clamping plate 7016. A roller follower 7020 is set in the roller ring groove. The roller follower 7020 is mounted on the slide of the slide cylinder 7022 through the follower seat 7021. The cylinder body of the slide cylinder 7022 is connected to the slide cylinder mounting base 7023 by screws and is fixed on the take-up drum seat 702 through the slide cylinder mounting base 7023.To ensure better entry of the optical fiber into the guide clamping plate 7016 and the positioning guide wheel 7015, a guide block 7024 is fixed around the circumference of the positioning guide wheel 7015 using screws. A take-up spool 7025 is fitted onto the take-up shaft 7014, close to the outer end face of the positioning guide wheel 7015. The take-up shaft drives the positioning guide wheel 7015, the guide clamping plate 7016, and the take-up spool 7025 to rotate, winding the optical fiber onto the take-up spool 7025.
[0079] In the take-up reel 7, the take-up shaft 7014 is connected to the power drive unit. In this embodiment, the power drive unit adopts a take-up servo motor 705, a take-up reducer 704, a take-up drive pulley 706, a take-up driven pulley 708, and a take-up drive shaft 707. The take-up drum 7025 is detachably mounted on the take-up shaft 7014. In this embodiment, the take-up shaft 7014 adopts an air expansion shaft to achieve detachable assembly with the take-up drum. When the air expansion shaft is not ventilated, the take-up drum can be freely assembled on the take-up shaft. When the air expansion shaft is ventilated, it locks the take-up drum 7024. The take-up shaft 7014 drives the take-up drum to rotate together with the air expansion shaft to take up the yarn. The positioning guide wheel 7015 is fixedly mounted on the take-up shaft 7014 at the end of the take-up drum 7025. The guide clamping disc 7016 is coaxially nested with the positioning guide wheel 7015, and an elastic guide assembly for mutual clamping is provided between the positioning guide wheel 7015 and the guide clamping disc 7016. The elastic guide assembly in this embodiment includes a compression spring 7017 and a linear bearing 7018. The compression spring 7017 provides elastic pressure to press the guide clamping disc 7016 and the positioning guide wheel 7015 together. The linear bearing 7018 provides guidance for the clamping and separating movement between the guide clamping disc 7016 and the positioning guide wheel 7015. The separation of the guide clamping disc 7016 and the positioning guide wheel 7015 forms a gap on the take-up drum for clamping the end of the optical fiber. After the positioning guide wheel 7015 and the guide clamping disc 7016 clamp the optical fiber, the pulled optical fiber can be automatically wound up. In this embodiment, the take-up reel is provided with a roller assembly that separates the guide clamping plate 7016 from the positioning guide wheel 7015. The roller assembly includes a roller ring 7019 and a roller follower 7020. The slide cylinder 7022 retracts and applies an axial pulling force to the roller ring 7019 through the roller follower 7020, separating the guide clamping plate 7016 from the positioning guide wheel 7015. The roller follower 7020 achieves rolling contact between the roller and the roller ring 7019, which does not affect the rotation of the guide clamping plate 7016 with the take-up shaft. The take-up spool is slidably mounted on the take-up linear module 701. The fiber punch 5 moves the pulled fiber into position and clamps it between the separate guide clamping plate 7016 and the positioning guide wheel 7015. The fiber is evenly wound onto the take-up drum 7025 through the linkage of the take-up shaft 7014 and the take-up linear module 701. The number of fiber winding turns is identified by detecting the rotation parameters of the take-up shaft 7014 through the take-up photoelectric switch 7011.
[0080] In practical applications, fiber optic take-up equipment can use a punch-hole device 5 in conjunction with a set of touch-controlled guide wheels 6 and a take-up reel 7 to improve fiber optic take-up production efficiency. Alternatively, a punch-hole device 5 can be used in conjunction with two sets of touch-controlled guide wheels 6 and two take-up reels 7.
[0081] like Figure 8 , Figure 13 and Figure 14 In this embodiment, the take-up device has two sets of take-up reels 7. A shuttle traction device pulls the optical fiber between the two sets of take-up reels 7. The clamping gaps between the positioning guide wheel 7015 and the guide clamping plate 7016 of the two sets of take-up reels 7 are located side by side on both sides of the optical fiber that has been pulled into position. The punch-hole device 5 is set on the switching linear module 502. By driving the punch-hole device to avoid the optical fiber, the hanging cylinder 5012 on the swing arm is moved to the left and right sides of the optical fiber, so that the punch-hole device 5 can guide the optical fiber from both sides of the optical fiber to the two sets of take-up reels 7 respectively. In addition, this embodiment also includes two sets of touch guide wheel groups 6 arranged side by side. The two sets of touch guide wheel groups 6 are respectively set between the two sets of take-up reels 7 and the optical fiber that has been pulled into position. They are arranged symmetrically on the base plate 601. The shuttle traction device pulls the optical fiber through the two sets of touch guide wheel groups 6. The fiber punch 5 sequentially moves the optical fiber pulled by the shuttle traction device to the take-up drums on both sides of the take-up reels for winding. While one side of the take-up reel is winding, the take-up drums on the other side can be picked up and put on, which improves the production efficiency of continuous optical fiber winding.
[0082] Example 3
[0083] See Figure 8 The fiber optic take-up device in this embodiment is further provided with a feed wheel assembly 2 based on the second embodiment. The feed wheel assembly 2 is used to adjust the fiber optic take-up device to adapt to the different traction forces caused by the change in fiber production rate during the fiber take-up process.
[0084] See also Figure 17 , Figure 18The feed roller assembly 2 includes a roller assembly panel 201, a wire feeding guide roller 202, a wire storage fixed roller 203, a wire storage moving roller assembly 204, a reversing roller 205, a pneumatic tension system 206, and a cable 207. All structures on the feed roller assembly 2 are mounted on the roller assembly panel 201, which is fixedly mounted on the upper frame 101. The guide roller 202 is mounted on the upper left of the roller assembly panel 201. Optical fibers are introduced into the feed roller assembly from the guide roller 202. The wire storage fixed roller 203 and the wire storage moving roller assembly 204 are horizontally arranged in the middle area of the roller assembly panel 201. The base of the wire storage fixed roller 203 is fixedly mounted on the roller assembly panel 201 and does not move. The wire storage wheel assembly 204 is slidably mounted on the wheel set panel 201 and includes a wire storage wheel 2041, a slider 2042, a tension plate 2043, a linear slide rail 2044, and a position sensor 2045. The wire storage wheel 2041 is mounted on the slider 2042 via the tension plate 2043. The slider 2042 is slidably mounted on the linear slide rail 2044. The linear slide rail 2044 is horizontally mounted on the wheel set panel 201 using screws. The installation height ensures that the wire storage wheel 2041 and the wire storage fixed wheel 203 are at the same height. The linear slide rail 2044 is arranged along the connecting line between the wire storage wheel 2041 and the wire storage fixed wheel 203. The wire storage wheel and the wire storage fixed wheel are provided with several optical fiber winding grooves. The optical fiber introduced from the lead wheel 202 is wound back and forth between the wire storage wheel and the wire storage fixed wheel multiple times. The cable storage pulley assembly 204 is connected to the pneumatic rod tensioning system 206 via a cable 207. Two reversing wheels 205 are vertically mounted on the lower right side of the wheel assembly panel 201, used for reversing the cable 207 connecting the cable storage pulley assembly to the pneumatic rod tensioning system 206. The pneumatic rod tensioning system 206 is mounted on the wheel assembly panel 201 below the cable storage pulley assembly using a rodless cylinder 2061. The pneumatic rod tensioning system 206 includes a rodless cylinder 2061, a tension sensor 2062, and a tension spring 2063. The slider of the rodless cylinder 2061 is connected to the tension sensor 2062 via a connecting plate and screws. The tension sensor 2062 is connected to the cable 207 via the tension spring 2063. The cable 207 passes around the two reversing wheels 205 and connects to the tension plate 2043 of the upper cable storage pulley assembly 204.
[0085] In this embodiment, the feed wheel assembly 2 is located on the feed side of the anti-reverse wheel assembly of the shuttle traction device. It has a thread storage wheel assembly with adjustable wheel spacing, namely a fixed thread storage wheel 203 and a moving thread storage wheel assembly 204 that slides relative to the fixed thread storage wheel. The optical fiber entering the take-up device is wound back and forth between the fixed thread storage wheel 203 and the moving thread storage wheel 2041 before being pulled to the shuttle traction device. The moving thread storage wheel assembly 204 is connected to the tension system. In this embodiment, a pneumatic tension system 206 is used. The pneumatic tension system 206 includes a tension adjustment drive unit, a cable, and a tension sensor. In this embodiment, the tension adjustment drive unit is a rodless cylinder 2061. The rodless cylinder 2061 is connected to the moving thread storage wheel 204 via the cable. The tension plate 2043 is connected to the cable 207. During the take-up process, the traction force of the optical fiber wound between the fixed storage wheel 203 and the moving storage wheel 2041, as well as the linear force of the rodless cylinder 2061, tightens the cable 207. The tension sensor 2062 installed on the cable 207 detects the tension of the cable 207 and directly feeds back the optical fiber traction force. The tension sensor 2062 is connected to the controller of the rodless cylinder 2061. By detecting the traction force of the optical fiber between the fixed storage wheel 203 and the moving storage wheel 2041 through the tension sensor 2062, the distance between the fixed storage wheel 203 and the moving storage wheel 2041 is adjusted by the rodless cylinder 2061 to adapt to different optical fiber traction forces. In practical applications, other linear actuators such as linear motors can also be used as the tension adjustment drive unit of the tension system.
[0086] In this embodiment, the wire inlet position and the wire outlet position of the wire inlet wheel group 2 are respectively the wire inlet guide wheel 202 provided on the wheel group panel 201 and the wire outlet guide wheel 302 provided on the wire outlet assembly support plate 301 of the backstop wheel group 3. The optical fiber 9 is pulled from the wire inlet guide wheel 202 to the wire storage fixed wheel and the wire storage moving wheel for wire storage, and is led out from the wire outlet guide wheel 302 into the backstop wheel group of the shuttle traction device.
[0087] See again Figure 8-18 The working process of this embodiment is as follows:
[0088] Step 1: After the optical fiber is produced, the optical fiber is manually pulled in from above the feed roller 202 of the feed roller group 2. After the feed roller 202 is reversed, the optical fiber is wound back and forth in the groove between the storage stationary roller 203 and the storage moving roller 2041. After winding, it returns to the storage stationary roller 203, and then reaches the output roller 302 of the anti-reverse roller group 3. After the output roller 302 is reversed, the optical fiber passes through the small hole in the middle of the lead guide rod 303 on the output assembly support plate 301 and continues to be introduced downward into the anti-reverse roller group.
[0089] Step Two: In the initial state, the shuttle 4 of the shuttle traction device is in operation. The shuttle rodless cylinder 402 is vented, driving the finger unit 406 upward. Simultaneously, the finger extension cylinder 4069 retracts the gripper finger 4063 of the finger unit 406, avoiding the backstop wheel assembly during the upward movement of the finger unit 406. After the finger unit 406 reaches its limit position, the finger extension cylinder 4069 drives the gripper finger 4063 to extend, and the gripper cylinder 4064 is vented, clamping the manually pulled optical fiber. At this time, the gripper finger 4063 of the finger unit 406 is located in the shuttle traction groove 307 above the position of the fixed roller 3041 and the moving roller 3051. At the same time, the second cam follower 4065 of the finger unit 406 is embedded in the cam guide groove 306 of the backstop wheel assembly.
[0090] Step 3: After the finger clamp 4063 of the finger unit 406 clamps the optical fiber, the shuttle rodless cylinder 402 is vented, causing the finger unit 406 to move vertically downwards along the optical fiber traction direction. During the downward movement of the finger unit 406, the second cam follower in the finger unit 406 contacts the cam surface in the cam guide groove 306. Under the pushing action of the cam, the finger clamp 4063 of the finger unit 406 moves laterally towards the moving wheel roller 3051 as it passes through the anti-reverse wheel group, avoiding the fixed wheel roller 3041. Simultaneously, the push plate 404 on the finger unit 406 moves downwards with the finger unit under the action of the shuttle rodless cylinder 402, and the cam surface on the push plate 404... The first cam group is formed by the first cam follower 3059 in the reverse stop wheel assembly 305, which drives the reverse stop fixed wheel assembly 305 to move laterally, separating the moving wheel roller 3051 and the fixed wheel roller 3041 of the reverse stop wheel assembly 3. The finger clamp 4063 in the finger unit 406 clamps the optical fiber smoothly through the reverse stop wheel assembly 3. The shuttle rodless cylinder 402 drives the finger clamp of the finger unit 406 to continue to move downward. After passing through the reverse stop wheel assembly, the moving wheel roller 3051 in the reverse stop wheel assembly 305 returns to its original position under the action of the moving wheel return spring 3056. At this time, the moving wheel roller 3051 and the fixed wheel roller 3041 press the rollers again to clamp the optical fiber pulled through by the shuttle.
[0091] Step 4: The finger clamp of the finger unit 406 continues to move downwards, passing between the two touch reversing wheels 607 symmetrically distributed in the two sets of touch guide wheel groups 6, and then reaches the lowest point. The shuttle rodless cylinder 402 stops air supply, and the shuttle pulls the optical fiber into place.
[0092] Step 5: With the swing arm 5011 of the punch-hole machine 5 in its initial right position, the linear module 502 is powered on, driving the groove of the hanging cylinder 5012 on the swing arm 5011 to be on the same swing plane as the fiber optic cable that has been pulled into place. The punch-hole machine motor 509 is powered on and rotates forward, causing the swing arm 5011 to swing to the left. The hanging cylinder 5012 above the swing arm 5011 hooks the fiber optic cable and pulls it to the left. The swing arm 5011 drives the hanging cylinder 5012 to reach the lowest point on the left end. The servo motor 509 stops rotating, and the swing arm 5011 remains stationary. During this process, the fiber optic cable will rest on the left-side touch-sensitive reversing wheel 607. Under the pressure of the continuous swing of the fiber optic cable, the left-side touch-sensitive reversing wheel 607 will slide to trigger the left-side contact switch 6010, sending a position signal indicating that the fiber optic cable has been guided into place before take-up.
[0093] Step 6: The take-up linear module 701 of the take-up reel 7 is powered on. The take-up reel 7 moves forward from the initial position under the drive of the take-up linear module 701. When the gap between the positioning guide wheel 7015 and the guide clamping plate 7016 is on the same plane as the optical fiber, the take-up linear module 701 stops moving. When the wire punch motor 509 of the wire punch 5 is energized and reverses, it drives the swing arm 5011 to lift 7° upward and then stop rotating, so that part of the optical fiber is located in the gap between the positioning guide wheel 7015 and the guide clamping plate 7016. The slide cylinder 7022 is vented and moves forward, driving the roller follower 7020 to release the guide clamping plate 7016. The guide clamping plate 7016 moves forward under the action of the compression spring 7017, and the gap between the guide clamping plate 7016 and the positioning guide wheel 7015 is closed. After the positioning guide wheel 7015 and the guide clamping plate 7016 clamp the optical fiber under the action of the compression spring, the take-up plate pulls the optical fiber to take it up. The clamping finger 4063 can then release the optical fiber and the shuttle 4 drives it to move back to the initial standby waiting position above the anti-reverse wheel group.
[0094] Step 7: The take-up linear module 701 of the take-up reel 7 is powered on and moves backward. The take-up reel 7 returns to its initial position under the drive of the take-up linear module 701. At this time, the optical fiber is disconnected from the wire bonding device 5. The wire bonding device motor 509 of the wire bonding device 5 is powered on and reverses, driving the swing arm 5011 back to the initial position on the left.
[0095] Step 8: After the gap between the positioning guide wheel 7015 and the guide clamping plate 7016 closes and clamps the optical fiber, the take-up linear module 701 is energized and moves back and forth. At the same time, the air shaft of the take-up shaft 7014 is vented and locked to the take-up roller mounted on it. The take-up servo motor 705 is energized and rotates, driving the positioning guide wheel 7015, the guide clamping plate 7016, and the take-up drum 7025 to rotate via a synchronous belt. At this time, the take-up drum 7025 rotates and moves back and forth, and the optical fiber is evenly wound on the take-up drum 7025. After winding is completed, the take-up linear module 701 returns to its initial position.
[0096] Step 9: The wire punch motor 509 of the wire punch 5 is powered on and reverses, driving the swing arm 5011 to swing to the right. The hanging cylinder 5012 on the swing arm 5011 hooks the left side of the optical fiber and swings to the right. The swing arm 5011 drives the hanging cylinder 5012 to reach the lowest point on the right end, and the wire punch motor 509 stops rotating and remains stationary.
[0097] Step 10: The take-up reel 7 on the right repeats Step 6. After the positioning guide wheel 7015 and the guide clamping plate 7016 of the take-up reel 7 clamp the optical fiber, the take-up reel 7 on the right returns to the initial position under the drive of the take-up straight module 701. The wire punch servo motor 509 is powered on and rotates forward, driving the swing arm 5011 back to the initial position on the right.
[0098] Step 11: At this point, the optical fiber is pulled from the left take-up reel to the right take-up reel and clamped. The optical fiber between the two take-up reels is swung by the swing arm 5011 and rests on the knife holder 5013. The cut-off cylinder 505 is vented, which drives the blade 506 to cut the optical fiber connected between the two take-up reels. The right take-up reel is directly pulled by the anti-reverse wheel group 3 and the right touch-controlled reversing wheel 607 to take up the optical fiber. The right take-up reel is controlled to repeat step eight. At the same time, the worker can take out the take-up drum 7025 that has been wound and wound on the left and replace it with a new take-up drum 7025 to prepare for the next round of take-up.
[0099] Step 12: After the take-up spool 7 on the right is wound, return to step 5 and repeat the cycle until all the optical fiber is wound.
[0100] In the entire optical fiber take-up equipment operation process described above, only step one is completed manually. If a wire breaks before the wire feed end of the anti-reverse wheel group during the take-up process, step one is completed manually and the subsequent steps are continued. Wire breaks that occur after the anti-reverse wheel group can be automatically re-pulled by the shuttle traction device.
[0101] Because the fiber winding speed is constant, while the production input speed on the fiber inlet side is not constant, when the fiber supply speed changes, the rodless cylinder 2061 in the pneumatic tension system 206 changes its position in real time based on the data detected by the tension sensor. The rodless cylinder changes the position of the wire storage wheel 2041 relative to the wire storage stationary wheel in the wire storage wheel assembly 204 via the cable 207, thereby ensuring that the tension value on the fiber remains constant. Specifically, as follows... Figure 8 and Figure 17As shown, when the fiber production speed slows down while the winding speed remains constant, the tension in the fiber increases. The tension sensor 2062 in the pneumatic tension system 206 transmits a signal to the controller of the rodless cylinder 2061, causing the rodless cylinder 2061 to move to the right. The storage wheel 2041 in the storage wheel assembly 204 moves to the left under the tension of the fiber, reducing the distance between the storage wheel 203 and the storage wheel 2041. This releases the fiber stored in the two storage wheels until the tension sensor 2062 in the pneumatic tension system 206 detects a normal tension value. At this point, the positions of all parts remain unchanged.
[0102] The optical fiber referred to in this embodiment is a plastic optical fiber, but the winding medium used in this invention is not limited to plastic optical fiber, and can also be used for the winding production of other wires with the same winding method as plastic optical fiber.
