Description

[Technical field]

[0001] This application claims priority to Chinese Patent Application No. 202010912294.0, filed on September 2, 2020, entitled “OPTICAL FIBER DISTRIBUTION DEVICE, AND OPTICAL FIBER SCHEDULING METHOD AND SYSTEM,” which is hereby incorporated by reference in its entirety.

[0002] The present application relates to the field of communications technology, and in particular to fiber optic distribution devices and fiber optic scheduling methods and systems. [Background technology]

[0003] With the popularization of fiber to the x (FTTX), optical fiber resources are applied more intensively. In scenarios such as data center, upstream optical distribution frame (ODF) of optical distribution network (ODN), and street cabinet, there are a large number of requirements for optical fiber scheduling and port-level optical cross-connect. As a result, the fiber scheduling operations performed by the personnel of optical fiber network operators are becoming increasingly heavy.

[0004] Therefore, there is a need to consider a fiber optic distribution device that can perform automatic fiber scheduling. Summary of the Invention

[0005] The embodiments of the present application provide an optical fiber distribution device and an optical fiber scheduling method and system. The optical fiber distribution device can implement automatic optical fiber scheduling. The technical solution description of the optical fiber distribution device and the optical fiber scheduling method and system is as follows.

[0006] One embodiment of the present application provides an optical fiber distribution device, the optical fiber distribution device comprising a distribution section, a connector retraction section, and a robotic system, the distribution section being provided with an optical fiber adapter, the optical fiber adapter being configured to connect to an optical fiber connector connected to an optical fiber; the connector retraction section being configured to receive the optical fiber connector and the optical fiber connected to the optical fiber connector; and the robotic system being configured to: extract a target optical fiber connector from an initial optical fiber adapter; retract the target optical fiber connector and the optical fiber connected to the target optical fiber connector into the connector retraction section; and remove the target optical fiber connector from the connector retraction section and insert the target optical fiber connector into the target optical fiber adapter.

[0007] The distribution section is provided with a fiber optic adapter configured to connect to the fiber optic connector such that the fiber optic adapter is connected to the fiber optic connector at the distribution section.

[0008] The connector entry section is configured to receive the optical fiber connector and the optical fiber connected to the optical fiber connector, and may be divided into three areas in the optical fiber direction, a connector placement area, an active fiber receiving area, and a fiber storage area, respectively, and the connector placement area is adjacent to the optical fiber connector.

[0009] The robotic system is the main operating component of the optical fiber distribution device and can implement operations such as inserting and removing the optical fiber connector into and from the optical fiber adapter, retracting the optical fiber connector and optical fiber into the connector receptacle, and removing the optical fiber connector from the connector receptacle.

[0010] In addition, the optical fiber distribution device may further include a controller, so that the controller can control the robotic system and various driving mechanisms to complete automatic optical fiber scheduling. In order to ensure the accuracy of the operation of the robotic system and various driving mechanisms, the optical fiber distribution device may further include various sensors, so that the controller can implement closed-loop control based on the data fed back by the sensors.

[0011] According to the optical fiber distribution device provided in this embodiment of the present application, when a target optical fiber connector is scheduled from an initial optical fiber adapter to a target optical fiber adapter, first, the target optical fiber connector is unplugged from the initial optical fiber adapter, and then the target optical fiber connector and optical fiber are retracted into the connector retractor. In the retracting process, the target optical fiber connector and optical fiber are retracted from the wrapped optical fiber cluster (if there is an optical fiber cluster) to avoid the optical fiber connected to the target optical fiber connector and the wrapping between other optical fibers. Then, the target optical fiber connector is removed from the connector retractor, and finally inserted into the target optical fiber adapter indicated by the scheduling command.

[0012] It can be seen that in the optical fiber scheduling process, the optical fiber distribution device provided in this embodiment of the present application pulls the optical fiber connector and the optical fiber into the connector pull-in section, and in the pull-in process, winding between the optical fiber connected to the target optical fiber connector and other optical fibers is avoided, so that the insertion and extraction robot does not need to travel a complicated route to bypass all the optical fibers that may be wound, thereby greatly shortening the time required for optical fiber scheduling.

[0013] In one possible implementation, the connector retraction section includes a plurality of connector receiving holes, the plurality of connector receiving holes corresponding one-to-one to the plurality of optical fiber connectors, the target optical fiber connector corresponds to the target connector receiving holes, and an optical fiber connected to the target optical fiber connector passes through the target connector receiving hole. When the target optical fiber connector and the optical fiber connected to the target optical fiber connector are retracted into the connector retraction section, the robotic system is configured to retract the target optical fiber passing through the target connector receiving hole into the connector retraction section and retract the optical fiber connector to which the target optical fiber is connected into the target connector receiving hole. When the target optical fiber connector is removed from the connector retraction section, the robotic system is configured to remove the optical fiber connector from the target connector receiving hole.

[0014] An optical fiber connected to each optical fiber connector passes through one connector receiving hole.

[0015] In the solution shown in this embodiment of the present application, the multiple connector receiving holes correspond one-to-one to the multiple optical fiber connectors, so that each optical fiber connector (or each optical fiber) has a determined position that is different from each other, and the optical fiber distribution device records the position of each optical fiber connector and prevents the optical fibers connected to the multiple optical fiber connectors from wrapping.

[0016] The location of the target connector hole (which corresponds to the target fiber optic connector) may be used to determine the location of the target fiber optic connector within the connector lead-in.

[0017] When the target optical fiber connector is retracted into the connector retractor, the robotic system retracts the optical fiber connector to which the optical fiber passing through the target connector receiving hole is connected into the target connector receiving hole and retracts the optical fiber into the connector retractor. When the target optical fiber connector is removed from the connector retractor, the robotic system removes the optical fiber connector from the target connector receiving hole. That is, the optical fiber dispensing device determines the identity of the optical fiber connector by using the connector receiving hole.

[0018] The position of the fiber optic adapter into which the fiber optic connector is inserted may be used to determine the position of the fiber optic connector within the distribution section.

[0019] In one possible implementation, the robotic system includes an insertion and extraction robot, a first fiber receiving mechanism, and a clamping jaw robot. The insertion and extraction robot is positioned on the dispensing station and configured to insert and extract fiber optic connectors into and from the fiber optic adapter. The first fiber receiving mechanism is positioned on the connector lead-in station and configured to draw the fiber optic connector and an optical fiber connected to the fiber optic connector into the connector lead-in. The clamping jaw robot is positioned on the connector lead-in station and configured to remove the fiber optic connector from the connector lead-in and transfer the removed fiber optic connector to the insertion and extraction robot.

[0020] In one possible implementation, the connector lead-in includes a connector repository, an active fiber receiving area, and a fiber storage area, the connector repository, the active fiber receiving area, and the fiber storage area being sequentially arranged in a direction of the optical fiber, the connector repository being proximate to the optical fiber connector, the clamp jaw robot being positioned within the connector repository, the first fiber receiving mechanism being positioned within the active fiber receiving area, and the fiber storage area being used to receive an optical fiber connected to the optical fiber connector.

[0021] The connector receptacles, the active fiber receiving areas, and the fiber storage areas may be arranged sequentially from top to bottom. The connector receptacles may be perpendicular to the distribution panels of the distribution section.

[0022] In the solution shown in this embodiment of the present application, a connector repository is used to store an optical fiber connector, and a connector receiving cavity may be located in the connector repository. An active fiber storage area is provided with a mechanism for storing an optical fiber. The mechanism can store the optical fiber connector in the connector repository and store the optical fiber in the fiber storage area. The fiber storage area is used to store an optical fiber, and the fiber storage area may be provided with a plurality of fiber storage cavities spaced apart from each other to avoid winding of the optical fiber in the fiber storage area.

[0023] In one possible implementation, the robotic system further includes a transport robot adjacent to both the distribution section and the connector repository and configured to transfer the fiber optic connectors delivered by the clamp jaw robot to the insertion and extraction robot.

[0024] The transport robot may be positioned within the connector repository or may be positioned above the distribution section.

[0025] In the solution presented in this embodiment of the present application, the action of the clamping jaw robot transferring the optical fiber connector to the insertion and extraction robot may be implemented by using a transport robot: first, the clamping jaw robot transfers the optical fiber connector to the transport robot, and then the transport robot transfers the optical fiber connector to the insertion and extraction robot.

[0026] In one possible implementation, the first fiber accommodating mechanism includes two fiber accommodating units, which are arranged opposite to each other. Each fiber accommodating unit includes a rotation shaft and a fiber accommodating wheel, the axial direction of the rotation shaft is parallel to the arrangement direction of the connector accommodating holes, the fiber accommodating wheel is keyed to the rotation shaft, and the fiber accommodating wheel is movable in the axial direction of the rotation shaft. The fiber accommodating wheel is provided with a protrusion in the circumferential direction, and the position of the protrusion of the fiber accommodating wheel of one fiber accommodating unit corresponds to the position of the protrusion of the fiber accommodating wheel of the other fiber accommodating unit. In the fiber accommodating state of the first fiber accommodating mechanism, the two protrusions clamp the optical fiber connected to the optical fiber connector and accommodate the optical fiber connected to the optical fiber connector by rotation.

[0027] In the solution shown in this embodiment of the present application, when the first fiber accommodating mechanism is in a fiber accommodating state, the two fiber accommodating wheels clamp the optical fiber and accommodate the optical fiber in the fiber storage area by rotating. In addition, the optical fiber connector is dragged by using the optical fiber, and the optical fiber connector is accommodated in the connector accommodating hole. However, in a non-fiber accommodating state, the non-protruding parts of the two fiber accommodating wheels face each other, and the distance between the two fiber accommodating wheels is large, so that the optical fiber is not clamped and the two fiber accommodating wheels may move axially. In this way, the two fiber accommodating wheels can accommodate at least one row of optical fibers.

[0028] In one possible implementation, the transport robot includes a transport robot base, a rollover drive, and a rollover plate. The rollover drive is fixed on the transport robot base, and the rollover drive is in transmission connection with the rollover plate. A connector carrying hole is provided on a surface of the rollover plate adjacent to the connector retraction, and a fiber optic connector is mounted in the connector carrying hole.

[0029] In the solution presented in this embodiment of the present application, a transport robot can transfer the fiber optic connectors by flipping a tipping plate, which, when in a horizontal position, can receive the fiber optic connectors inserted by the clamping jaw robot, and which, when in a vertical position, can be clamped by an insertion and extraction robot from the tipping plate.

[0030] In one possible implementation, the connector repository includes a transport robot track and a transport robot synchronous belt assembly, the axial direction of the transport robot track is perpendicular to the arrangement direction of the connector receiving holes, the transport robot track is positioned on one side of the connector repository, and the transport robot synchronous belt assembly is positioned inside the transport robot track, and the transport robot base is aligned with the transport robot track and fixedly connected to the transport robot synchronous belt assembly.

[0031] In the solution shown in this embodiment of the present application, the transport robot can move along a transport robot track, and the power for the transport robot to move is provided by a transport robot synchronous belt assembly. The transport robot moves so that the transport robot can take on the transport of more fiber optic connectors.

[0032] In one possible implementation, the clamp jaw robot includes a clamp jaw robot base, a laterally movable base, a clamp mechanism, a clamp jaw pair, and a clamp jaw rotation drive. The laterally movable base is slidably connected to the clamp jaw robot base, and a sliding direction is perpendicular to the arrangement direction of the connector receiving holes. The clamp jaw rotation drive is fixed on the laterally movable base, and the clamp jaw pair is sleeve-connected on a rotation shaft of the clamp jaw rotation drive. The clamp mechanism is positioned on the laterally movable base and configured to tighten or loosen the clamp jaw pair.

[0033] In the solution shown in this embodiment of the present application, the clamp jaw pair can implement the clamping, loosening, and extraction actions on the optical fiber connector. The clamp mechanism can implement the clamping and loosening actions of the clamp jaw pair on the optical fiber connector by clamping or loosening the clamp jaw pair. The clamp jaw rotation drive can rotate the clamp jaw pair to implement the extraction action on the optical fiber connector. After the clamp jaw pair clamps the optical fiber connector, the clamp jaw rotation drive can rotate the clamp jaw pair to extract the optical fiber connector from the connector receiving hole. The clamp mechanism, the clamp jaw pair, and the clamp jaw rotation drive can be fixed on a laterally movable base, which is slidably connected to the clamp jaw robot base, and the sliding direction is perpendicular to the arrangement direction of the connector receiving hole. In this way, the clamp jaw pair can move closer to or away from the optical fiber connector.

[0034] In one possible implementation, the clamp mechanism includes a clamp driver, a drive connecting rod, and two clamp arms. The intermediate portions of the two clamp arms are hinged, the hinge point is fixed, the clamp arms are provided with connecting protrusions, and the drive connecting rod is provided with connecting holes at both ends, the connecting protrusions of the two clamp arms are respectively positioned within the connecting holes at both ends of the drive connecting rod, and the connecting protrusions are slidable within the connecting holes. Each clamp end of the two clamp arms clamps one clamp jaw of the clamp jaw pair. The push rod of the clamp driver is fixedly connected to the drive connecting rod, and the push rod is perpendicular to the drive connecting rod.

[0035] In the solution shown in this embodiment of the present application, when the clamp mechanism performs clamping, the push rod of the clamp drive device extends outward and drives the drive connecting rod to move, so that the two clamp arms move towards each other under the pressure of the drive connecting rod, and the two clamp arms drive the clamp jaw pairs to implement the clamping operation.

[0036] When the clamp mechanism performs loosening, the push rod of the clamp drive retracts inward, driving the drive connecting rod to move, so that the two clamp arms move away from each other under the drive of the drive connecting rod, and the two clamp arms drive the clamp jaw pair to implement the loosening operation.

[0037] In one possible implementation, the connector placement site is provided with a clamp jaw robot guide rail and a clamp jaw robot synchronous belt assembly. An axial direction of the clamp jaw robot guide rail and a moving direction of the clamp jaw robot synchronous belt assembly are parallel to an arrangement direction of the connector receiving holes. A clamp jaw robot base of the clamp jaw robot is aligned with the clamp jaw robot guide rail and is fixedly connected to the clamp jaw robot synchronous belt assembly.

[0038] In the solution shown in this embodiment of the present application, the clamp jaw robot can move along a clamp jaw robot guide rail, and the power for the clamp jaw robot movement is provided by a clamp jaw robot synchronous belt assembly.

[0039] In one possible implementation, the clamp jaw robot further includes a clamp plate that corresponds to the position of the clamp jaw pair in the vertical direction, the clamp plate fixedly connected to the clamp jaw robot base, the clamp plate clamping the fiber storage wheel in the first fiber storage mechanism.

[0040] In the solution presented in this embodiment of the present application, the fiber-containing wheel can be moved along the axis of rotation by driving the clamp plate, which is fixed on the clamp jaw robot base, so that when the clamp jaw robot moves, it drives the fiber-containing wheel to move within the clamp plate.

[0041] The clamp plate corresponds to the position of the clamp jaw pair in the vertical direction, so that after the clamp jaw robot drives the fiber-storing wheel to move to the target position and completes the fiber-storing, the clamp jaw robot does not need to move and can clamp the optical fiber connector by using the clamp jaw pair.

[0042] In one possible implementation, the insertion and extraction robot includes an insertion and extraction robot base, an insertion and extraction base, two clamp bases, and two clamp arms. The insertion and extraction base is slidably connected to the insertion and extraction robot base in a first direction, the first direction being perpendicular to the dispensing section. The two clamp bases are positioned on the insertion and extraction base and slidably connected to the insertion and extraction base in a second direction, the movement directions of the two clamp bases are opposite, and the second direction is parallel to the axial direction of the clamp jaw robot guide rail. The two clamp arms are positioned on the two clamp bases respectively, and the clamp arms are slidably connected to the clamp bases in a third direction, the third direction being perpendicular to both the first direction and the second direction.

[0043] In the solution shown in this embodiment of the present application, the insertion and extraction base is slidably connected to the insertion and extraction robot base in a first direction, and the two clamp arms are both positioned on the insertion and extraction base, so that the insertion and extraction base can drive the two clamp arms to move bidirectionally in the first direction to implement the insertion and extraction operations on the optical fiber connector.

[0044] The two clamp bases are slidably connected to the insertion and extraction base in a second direction, and the moving directions of the two clamp bases are opposite. In addition, the two clamp arms are respectively positioned on the two clamp bases. Thus, the clamp bases can drive the two clamp arms to move away from or towards each other in the second direction to implement clamping and loosening operations on the optical fiber connector.

[0045] The two clamp arms are slidably connected to the clamp base in a third direction, such that the two clamp arms can extend and retract relative to the clamp base to implement avoidance of the fiber optic adapter by an insertion and extraction robot.

[0046] In one possible implementation, the distribution section includes an insert and extract robot track and an insert and extract robot synchronous belt assembly, the insert and extract robot synchronous belt assembly being positioned inside the insert and extract robot track. The insert and extract robot track is positioned on one side of at least one row of fiber optic adapters. The insert and extract robot is aligned with the insert and extract robot track and engaged with the insert and extract robot synchronous belt assembly.

[0047] In the solution presented in this embodiment of the present application, the insertion and extraction robot can move along the insertion and extraction robot track close to multiple different fiber optic adapters to insert and extract more fiber optic connectors. The insertion and extraction robot track provides a running track for the insertion and extraction robot, and the insertion and extraction robot synchronous belt assembly provides running power for the insertion and extraction robot.

[0048] In one possible implementation, there are multiple rows of insert and extract robot tracks and the robot system further includes a row change robot positioned on the distribution section and configured to transfer the insert and extract robots to the multiple different insert and extract robot tracks.

[0049] In the solution shown in this embodiment of the present application, the insertion and extraction robot may be transferred to multiple different insertion and extraction robot tracks by positioning the row change robot, so that one insertion and extraction robot can insert and extract optical fiber connectors near multiple rows of insertion and extraction robot tracks.

[0050] In one possible implementation, the row-changing robot includes a row-changing robot base, a row-changing track, and a row-changing synchronous belt assembly, the row-changing track is fixed on the row-changing robot base, and the row-changing synchronous belt assembly is positioned inside the row-changing track. The distribution section further includes a lead screw mechanism, an axial direction of the lead screw mechanism is parallel to an alignment direction of the multiple rows of the insertion and extraction robot tracks, and the row-changing robot base is aligned with the lead screw mechanism. In a row-changing state of the insertion and extraction robot, the insertion and extraction robot is aligned with the row-changing track and engaged with the row-changing synchronous belt assembly.

[0051] In the solution shown in this embodiment of the present application, the insert and extract robots may be jointly driven to the row changing robot by the row changing synchronous belt assembly and the insert and extract robot synchronous belt assembly. In addition, the insert and extract robots may be limited to the row changing robot due to the lateral limitations of the row changing track and the vertical limitations of the row changing synchronous belt assembly.

[0052] A lead screw mechanism allows the row change robot to move to multiple different insert and extract robot tracks, so that the row change track can be easily connected to multiple different insert and extract robot tracks. The insert and extract robots can then again be driven to the insert and extract robot tracks jointly by the row change synchronous belt assembly and the insert and extract robot synchronous belt assembly.

[0053] In one possible implementation, the robotic system includes a dispensing robot and a second fiber receiving mechanism. The dispensing robot is positioned between the dispensing section and the connector retract section and is configured to insert and extract fiber optic connectors from the fiber optic adapters and remove the fiber optic connectors from the connector retract section. The second fiber receiving mechanism is positioned over the connector retract section and is configured to retract the fiber optic connectors and the optical fibers connected to the fiber optic connectors into the connector retract section.

[0054] In the solution presented in this embodiment of the present application, the dispensing robot can implement all the functions of an insertion and extraction robot, a clamping jaw robot, a transport robot and a row change robot.

[0055] The second fiber accommodating mechanism may be the same as the first fiber accommodating mechanism, i.e., the second fiber accommodating mechanism includes two fiber accommodating units, and the two fiber accommodating units are arranged opposite to each other. Each fiber accommodating unit includes a rotating shaft and a fiber accommodating wheel, the axial direction of the rotating shaft is parallel to the arrangement direction of the connector accommodating holes, the fiber accommodating wheel is keyed to the rotating shaft, and the fiber accommodating wheel is movable in the axial direction of the rotating shaft. The fiber accommodating wheel is provided with a protrusion in the circumferential direction, and the position of the protrusion of the fiber accommodating wheel of one fiber accommodating unit corresponds to the position of the protrusion of the fiber accommodating wheel of the other fiber accommodating unit. In the fiber accommodating state of the first fiber accommodating mechanism, the two protrusions clamp the optical fiber connected to the optical fiber connector and accommodate the optical fiber connected to the optical fiber connector by rotation.

[0056] In one possible implementation, the connector lead-in includes a connector repository, an active fiber receiving area, and a fiber storage area, the connector repository, the active fiber receiving area, and the fiber storage area being sequentially arranged in a direction of the optical fiber, the connector repository being proximate to the optical fiber connector, and the second fiber receiving mechanism being positioned within the active fiber receiving area.

[0057] In the solution shown in this embodiment of the present application, a connector repository is used to store an optical fiber connector, and a connector receiving cavity may be located in the connector repository. An active fiber storage area is provided with a mechanism for storing an optical fiber. The mechanism can store the optical fiber connector in the connector repository and store the optical fiber in the fiber storage area. The fiber storage area is used to store an optical fiber, and the fiber storage area may be provided with a plurality of fiber storage cavities spaced apart from each other to avoid winding of the optical fiber in the fiber storage area.

[0058] In one possible implementation, the dispensing robot includes a first guide rail, a second guide rail, a third guide rail, and a clamping mechanism. The first guide rail is fixed to a bottom of the optical fiber dispensing device, the second guide rail is slidably connected to the first guide rail, and the third guide rail is fixed on the second guide rail, and the axial directions of the first guide rail, the second guide rail, and the third guide rail are perpendicular to each other. The clamping mechanism is slidably connected to the third guide rail and configured to clamp and loosen the optical fiber connector.

[0059] In the solution shown in this embodiment of the present application, the clamping mechanism can move to each point in space by arranging the first guide rail, the second guide rail, and the third guide rail perpendicular to each other, so that the operations of the distribution robot inserting and extracting the optical fiber connector in the distribution section, extracting the optical fiber connector from the connector storage area, transporting the optical fiber connector from the connector storage area to the distribution section, and avoiding the optical fiber can be implemented.

[0060] In one possible implementation, the clamp mechanism includes a first clamp arm, a second clamp arm, and a clamp driver, the first clamp arm slidably connected to the second clamp arm, and the clamp driver is drivingly connected to the first clamp arm and configured to drive a clamped end of the first clamp arm away from or toward the clamped end of the second clamp arm.

[0061] In the solution shown in this embodiment of the present application, the clamp driver drives the clamping end of the first clamp arm away from or towards the clamping end of the second clamp arm, so that the first clamp arm and the second clamp arm can clamp or unclamp the optical fiber connector.

[0062] In one possible implementation, the fiber storage area includes a gravity ring that is hung around optical fibers connected to fiber optic connectors.

[0063] In the solution shown in this embodiment of the present application, the gravity ring can be arranged to apply a pulling force to the optical fiber, so that the optical fiber is in a slightly tensioned state and the optical fiber is less likely to get caught in the optical fiber cluster, thereby ensuring the operability of pulling the optical fiber in. In addition, the optical fiber will not get wrapped or tangled due to the excess length of the optical fiber.

[0064] In addition, the optical fiber is in a slightly tensioned state instead of fully stretched, so the optical fiber can be a generic optical fiber instead of a customized tension-bearing optical fiber, thereby reducing the manufacturing cost of the optical fiber.

[0065] In one possible implementation, the fiber optic connector is provided with a guide structure in an axial direction, and the outer diameter of the fiber optic connector is 1 to 5 times the outer diameter of the optical fiber connected to the fiber optic connector.

[0066] The guide features may be one or more of rounded and chamfered features.

[0067] In the solution presented in this embodiment of the present application, the optical fiber connector is provided with a guide structure in the axial direction, and the outer diameter of the optical fiber connector is small, so that the optical fiber connector is easier to be pulled out of the wound optical fiber cluster and is less likely to get caught on the optical fiber cluster, thereby improving the success rate of accommodating the optical fiber.

[0068] According to a second aspect, there is provided an optical fiber scheduling method, the method being applied to the optical fiber distribution device described above, the method comprising the steps of controlling the robotic system to unplug a target optical fiber connector from an initial optical fiber adapter; retracting the target optical fiber connector and an optical fiber connected to the target optical fiber connector into the connector retraction section; and removing the target optical fiber connector from the connector retraction section and inserting the target optical fiber connector into the target optical fiber adapter.

In addition, when scheduling an optical fiber, the optical fiber distribution device will draw the optical fiber connector and the optical fiber into the connector drawer, and in the drawing process, the winding between the optical fiber connected to the target optical fiber connector and other optical fibers is avoided, so that the insertion and extraction robot does not need to travel a complicated route to bypass all the optical fibers that may be wound, which greatly reduces the time required for optical fiber scheduling.

[0133] Some embodiments of the present application provide an optical fiber distribution device. The optical fiber distribution device may implement automatic fiber scheduling and may be used in any scenario with requirements for optical fiber scheduling. For example, the optical fiber distribution device may be used in scenarios such as data centers, upstream optical distribution frames (ODFs) of optical distribution networks (ODNs), and street cabinets.

[0134] An embodiment of the present application provides an optical fiber distribution device. As shown in Figures 1 and 20, the optical fiber distribution device includes a distribution unit 1, a connector pulling unit 2, and a robot system 3. The distribution unit 1 is provided with an optical fiber adapter, which is configured to connect to an optical fiber connector connected to an optical fiber. The connector retraction unit 2 is configured to receive a fiber optic connector and an optical fiber connected to the fiber optic connector. The robotic system 3 is configured to extract a target fiber optic connector from an initial fiber optic adapter; retract the target fiber optic connector and the optical fiber connected to the target fiber optic connector into the connector retraction unit 2; and remove the target fiber optic connector from the connector retraction unit 2 and insert the target fiber optic connector into the target fiber optic adapter.

[0135] The distribution unit 1 is provided with a fiber optic adapter configured to connect to a fiber optic connector, such that the fiber optic adapter is connected to the fiber optic connector at the distribution unit 1 .

[0136] The connector retracting unit 2 is configured to accommodate an optical fiber connector and an optical fiber connected to the optical fiber connector. The connector retracting unit 2 includes a plurality of connector receiving holes 2111, which correspond one-to-one to a plurality of optical fiber connectors, so that the optical fiber distributing device determines the position of the optical fiber connector by using the connector receiving holes. When the robot system 3 needs to operate an optical fiber connector, the robot system may first drive a corresponding robot or mechanism to move close to the connector receiving hole corresponding to the optical fiber connector, and then perform a corresponding operation on the optical fiber connector or optical fiber corresponding to the connector receiving hole. For example, when a target optical fiber connector and a connected optical fiber are retracted into the connector retracting unit 2, the robot system 3 retracts the optical fiber connector to which the optical fiber passing through the target connector receiving hole is connected into the target connector receiving hole, and retracts the optical fiber into the connector retracting unit. When the target optical fiber connector is removed from the connector retracting unit 2, the robot system 3 removes the optical fiber connector from the target connector receiving hole. In this way, it can be guaranteed that the receiving position of the optical fiber connector is determined and unique. The connector entrance 2 may be divided into three areas in the optical fiber direction, namely, a connector placement area 21, an active fiber receiving area 22, and a fiber storage area 23, and the connector placement area 21 is adjacent to the optical fiber connector. The connector placement area 21 is used to place the optical fiber connector, the active fiber receiving area 22 is provided with a mechanism that can actively receive the fiber, and the fiber storage area 23 is used to store the optical fiber.

[0137] The robot system 3 is a main operating component of the optical fiber distribution device, and can implement operations such as inserting an optical fiber connector into an optical fiber adapter and removing it therefrom, retracting an optical fiber connector and an optical fiber into the connector retraction section 2, and removing an optical fiber connector from the connector retraction section 2. The robot system 3 may be implemented in a number of ways, but this application does not specifically limit this.

[0138] In addition, the optical fiber distribution device may further include a controller, so that the controller can control the robot system 3 and various driving mechanisms to complete automatic optical fiber scheduling. In order to ensure the accuracy of the operation of the robot system 3 and various driving mechanisms, the optical fiber distribution device may further include various sensors, so that the controller can implement closed-loop control based on the data fed back by the sensors.

[0139] The optical fiber distribution device provided in this embodiment of the present application can implement automatic optical fiber scheduling. When a target optical fiber connector is scheduled from an initial optical fiber adapter to a target optical fiber adapter, first, the target optical fiber connector is extracted from the initial optical fiber adapter, and then the target optical fiber connector and optical fiber are retracted into the connector retractor. In the retracting process, the target optical fiber connector and optical fiber are retracted from the wrapped optical fiber cluster (if there is an optical fiber cluster) to avoid wrapping between the optical fiber connected to the target optical fiber connector and other optical fibers. Then, the target optical fiber connector is removed from the connector retractor 2, and finally inserted into the target optical fiber adapter indicated by the scheduling command.

[0140] It can be seen that in the optical fiber scheduling process, the optical fiber distribution device provided in this embodiment of the present application pulls the optical fiber connector and the optical fiber into the connector pull-in section, and in the pull-in process, winding between the optical fiber connected to the target optical fiber connector and other optical fibers is avoided, so that the insertion and extraction robot does not need to travel a complicated route to bypass all the optical fibers that may be wound, thereby greatly shortening the time required for optical fiber scheduling.

[0141] In order to ensure that the optical fiber and the optical fiber connector can be smoothly pulled out of the optical fiber cluster, the optical fiber connector is provided with a guide structure in the axial direction (for example, the guide structure is a round structure and / or a chamfered structure), and the outer diameter of the optical fiber connector is 1 to 5 times the outer diameter of the optical fiber connected to the optical fiber connector, as shown in Figure 5. In this way, the optical fiber connector has a small outer diameter and a guide structure, and is not easily caught on the optical fiber.

[0142] In addition, the optical fiber may be kept in a slightly tensioned state, so that the optical fiber is less likely to get caught in the optical fiber cluster, thereby ensuring the maneuverability of pulling the optical fiber. In addition, the optical fiber does not get wrapped or tangled due to excess optical fiber length. To implement the slightly tensioned state of the optical fiber, the fiber storage area 23 may further include a gravity ring 232, as shown in FIG. 4 and FIG. 6. Each fiber storage cavity 231 is provided with a gravity ring 232, which may be hung on the optical fiber in the fiber storage cavity 231, so that a taut pulling force is applied to the optical fiber by using the gravity of the gravity ring. For example, the optical fiber may be wound on the gravity ring 232 in a winding manner shown by the dashed line in FIG. 5. In addition, a low-friction jacket may be used on the optical fiber to reduce friction between the optical fibers.

[0143] The optical fiber is not fully stretched but is slightly under tension, so the optical fiber can be a generic optical fiber instead of a customized strain-resistant optical fiber, thereby reducing the manufacturing cost of the optical fiber.

[0144] The optical fiber distribution device provided in this embodiment of the present application will be described below with reference to FIGS.

[0145] As shown in FIG. 1, the distribution panel and the connector entrance panel (ie, connector pit 21) of the optical fiber distribution device are perpendicular to each other.

[0146] As shown in FIG. 2, the connector entrance 2 may be divided into three areas, a connector storage area 21, an active fiber receiving area 22, and a fiber storage area 23, from top to bottom.

[0147] The connector storage 21 is used to store optical fiber connectors, and the connector storage 21 is provided with one or more connector accommodating bases 211, as shown in Fig. 3a. As shown in Fig. 3b, the connector accommodating base 211 is provided with a plurality of connector accommodating holes 2111, and the plurality of connector accommodating holes 2111 may be arranged in a direction parallel to the distribution unit 1 (the x-direction indicated by the arrow in the figure). Each connector accommodating hole 2111 is configured to accommodate an optical fiber connector, and an optical fiber connected to the optical fiber connector passes through the connector accommodating hole 2111. In one possible implementation, in order to easily accommodate the optical fiber connector, the connector accommodating hole 2111 may be a stepped hole, and the optical fiber connector may be placed on the stepped base of the stepped hole.

[0148] A mechanism capable of receiving an optical fiber is provided in the active fiber receiving area 22. The fiber receiving principle of this mechanism may be to receive the optical fiber connector in the connector storage area 21 by dragging the optical fiber of the optical fiber connector, and to receive the optical fiber in the fiber storage area 23.

[0149] The fiber storage area 23 is used to store optical fibers connected to the optical fiber connector. In order to prevent the stored optical fibers from wrapping, as shown in Fig. 4, the fiber storage area 23 may be provided with a plurality of fiber storage cavities 231 (only four fiber storage cavities are shown in the figure as an illustrative example), which are spaced apart from each other, and each fiber storage cavity 231 is configured to store one optical fiber. In addition, the plurality of fiber storage cavities 231 correspond one-to-one to the plurality of connector receiving holes 2111.

[0150] 1, the robot system 3 includes an insertion and extraction robot 31, a first fiber receiving mechanism 32, and a clamp jaw robot 33. The insertion and extraction robot 31 is positioned on the distribution station 1 and configured to insert and extract optical fiber connectors into and from optical fiber adapters. The first fiber receiving mechanism 32 is positioned within the active fiber receiving area 22 of the connector retraction station 2 and configured to retract optical fiber connectors and optical fibers connected to the optical fiber connectors into the connector retraction station 2. The clamp jaw robot 33 is positioned within the connector storage area 21 of the connector retraction station 2 and configured to retrieve optical fiber connectors from the connector retraction station 2 and transfer the retrieved optical fiber connectors to the insertion and extraction robot 31.

[0151] In the following, the insertion and extraction robot 31, the first fiber receiving mechanism 32 and the clamp jaw robot 33 will be described in detail according to the working sequence of the robots in the optical fiber scheduling process.

[0152] (1) First, the insertion and extraction robot 31 needs to extract the target fiber optic connector from the initial fiber optic adapter and release the target fiber optic connector.

[0153] As shown in FIG. 7, the insertion and extraction robot 31 includes an insertion and extraction robot base 311, an insertion and extraction base 312, two clamp bases 313, and two clamp arms 314. The insertion and extraction base 312 is slidably connected to the insertion and extraction robot base 311 in a first direction (i.e., x direction), the first direction being perpendicular to the distribution unit 1. The two clamp bases 313 are positioned on the insertion and extraction base 312 and slidably connected to the insertion and extraction base 312 in a second direction (i.e., y direction), the second direction being parallel to the axial direction of the clamp jaw robot guide rail 214, and the moving directions of the two clamp bases 313 are opposite to each other. The two clamp arms 314 are positioned on the two clamp bases 313 respectively, and the clamp arms 314 are slidably connected to the clamp bases 313 in a third direction (i.e., z direction), the third direction being perpendicular to both the first direction and the second direction.

[0154] The insertion and extraction robot base 311 may include two support plates 3121 configured to mount the drive mechanism of the clamp arm 314 and the drive mechanism of the clamp base 313. A clamp groove may be provided at the end of the clamp arm 314 to facilitate clamping the optical fiber connector. To allow the insertion and extraction robot 31 to handle the insertion and extraction of more optical fiber connectors, clamp grooves may be provided at both ends of the clamp arm 314, so that the insertion and extraction robot 31 may handle the insertion and extraction of optical fiber connectors on both sides.

[0155] The insertion and extraction base 312 is slidably connected to the insertion and extraction robot base 311 in the z-direction, and the two clamp arms 314 are both positioned on the insertion and extraction base 312. Thus, the insertion and extraction base 312 can drive the two clamp arms 314 to move bidirectionally in the z-direction to implement insertion and extraction operations on the optical fiber connector.

[0156] The two clamp bases 313 are slidably connected to the insertion and extraction base 312 in the y direction, and the moving directions of the two clamp bases 313 are opposite. In addition, the two clamp arms 314 are respectively positioned on the two clamp bases 313. Therefore, the clamp base 313 can drive the two clamp arms 314 to move away from or towards each other in the y direction to implement clamping and loosening operations on the optical fiber connector.

[0157] The two clamp arms 314 are slidably connected to the clamp base 313 in the x-direction. Thus, the two clamp arms 314 can extend and retract with respect to the clamp base 313 to implement an operation of avoiding the optical fiber adapter by the insertion and extraction robot 31. In a traveling state of the insertion and extraction robot 31, the two clamp arms 314 may retract to avoid the optical fiber adapter. In an insertion and extraction state of the insertion and extraction robot 31, the two clamp arms 314 extend.

[0158] In this embodiment of the present application, there is no specific limitation on the driving manner of the insertion and extraction base 312, the clamp base 313, and the clamp arm 314. For example, one possible implementation is provided.

[0159] As shown in Fig. 7, the driving device of the insertion and extraction base 312 includes an insertion and extraction driving motor 312a and an insertion and extraction driving feed screw 312b. The insertion and extraction driving motor 312a is fixed on the insertion and extraction base 312, and the insertion and extraction driving feed screw 312b is rotatably connected to the insertion and extraction robot base 311. The insertion and extraction base 312 is provided with a nut structure that matches the insertion and extraction driving feed screw 312b. When the insertion and extraction driving motor 312a rotates and drives the insertion and extraction driving feed screw 312b, the insertion and extraction driving feed screw 312b drives the insertion and extraction base 312 to move in a direction perpendicular to the distribution unit 1 (i.e., move in the z-axis direction) to implement the insertion and extraction operations on the optical fiber connector.

[0160] The driving device of the clamp base 313 includes a clamp drive motor 313a and a clamp drive feed screw 313b. The clamp drive motor 313a is positioned on the support plate 3121 of the insertion and extraction base 312, and the output shaft of the clamp drive motor 313a is fixedly connected to the clamp drive feed screw 313b. The clamp drive feed screw 313b passes through the two clamp bases 313, and the two clamp bases 313 are provided with nut structures that match the clamp drive feed screw 313b. In addition, in order to implement the opposite movement directions of the two clamp bases 313, the clamp drive feed screw 313b has two opposite rotation directions (correspondingly, the rotation directions of the two nut structures are also opposite), and the two rotation directions respectively correspond to the two clamp bases 313. When the clamp drive motor 313a rotates the clamp drive feed screw 313b, the clamp drive feed screw 313b drives the two clamp bases 313, thereby driving the two clamp arms 314 to move closer to or away from each other (i.e., move in opposite directions in the y-axis direction), thereby implementing the clamping operation.

[0161] The driving device of the clamp arm 314 includes a telescopic drive motor 314a and a gear column 314b. The telescopic drive motor 314a is positioned on the support plate 3121 of the insertion and extraction base 312. The output shaft of the telescopic drive motor 314a is fixedly connected to the gear column 314b, and the gear column 314b is engaged with the two clamp arms 314 (the two clamp arms 314 are provided with rack structures). When the telescopic drive motor 314a rotates and drives the gear column 314b, the gear column 314b drives the two clamp arms 314 to extend and retract (i.e., move in the x-direction) relative to the clamp base 313 to implement the operation of avoiding the optical fiber adapter.

[0162] The insertion and extraction robot 31 may further move on the distribution section 1 so that the insertion and extraction robot 31 can handle the insertion and extraction of more optical fiber connectors. This application does not specifically limit a specific implementation of the movement of the insertion and extraction robot 31. The following provides one possible implementation.

[0163] 8, the distribution section 1 includes an insertion and extraction robot track 11 and an insertion and extraction robot synchronous belt assembly 12, and the insertion and extraction robot synchronous belt assembly 12 is positioned inside the insertion and extraction robot track 11. The insertion and extraction robot track 11 is positioned on one side of at least one row of optical fiber adapters (arranged in the y direction). An insertion and extraction robot 31 is aligned with the insertion and extraction robot track 11 and engaged with the insertion and extraction robot synchronous belt assembly 12 (not shown).

[0164] The insertion and extraction robot track 11 and the insertion and extraction robot synchronous belt assembly 12 are positioned within grooves in the distribution section 1 aligned in the y direction to align the insertion and extraction robot 31 with the optical fiber connector and prevent the insertion and extraction robot 31 from being too taller than the optical fiber connector.

[0165] The insertion and extraction robot track 11 coincides with the insertion and extraction robot base 311 to form a linear pair. The insertion and extraction robot track 11 may constrain the insertion and extraction robot base 311 such that the insertion and extraction robot 31 can only move along the insertion and extraction robot track 11 and cannot become separated from the insertion and extraction robot track 11. Power for the insertion and extraction robot 31 to move may be provided by the insertion and extraction robot synchronous belt assembly 12.

[0166] The insertion and extraction robot synchronous belt assembly 12 includes an insertion and extraction robot synchronous belt 121 and an insertion and extraction robot rotating wheel 122. Synchronous teeth are arranged on both the outer wall of the insertion and extraction robot rotating wheel 122 and the inner side of the insertion and extraction robot synchronous belt 121 and are engaged with each other, so that the insertion and extraction robot rotating wheel 122 can rotate and drive the insertion and extraction robot synchronous belt 121. In addition, synchronizing teeth are also arranged on both the outer side of the insertion and extraction robot synchronous belt 121 and the insertion and extraction robot base 311 and are engaged with each other, so that the insertion and extraction robot synchronous belt 121 can drive and move the insertion and extraction robot 31. The insertion and extraction robot rotating wheel 122 may be driven by a motor.

[0167] When there are multiple rows of insert and remove robot tracks 11, it is necessary to switch the insert and remove robot 31 on the multiple different rows of insert and remove robot tracks 11. To implement this switching operation, as shown in Fig. 9, the robot system 3 may further include a row change robot 35. The row change robot 35 is positioned on the distribution section 1 and configured to transfer the insert and remove robot 31 to the multiple different insert and remove robot tracks 11.

[0168] 9, the row change robot 35 includes a row change robot base 351, a row change track 352, and a row change synchronous belt assembly 353, the row change track 352 is fixed on the row change robot base 351, and the row change synchronous belt assembly 353 is positioned inside the row change track 352. As shown in FIG. 10, the distribution unit 1 further includes a feed screw mechanism 13, the axial direction of the feed screw mechanism 13 is parallel to the arrangement direction of the multiple rows of insertion and extraction robot tracks 11, and the row change robot base 351 coincides with the feed screw mechanism 13. In the row change state of the insertion and extraction robot 31, the insertion and extraction robot 31 coincides with the row change track 352 and is engaged with the row change synchronous belt assembly 353.

[0169] The row change track 352 may match and form a linear pair with the insertion and extraction robot base 311. The row change track 352 may constrain the insertion and extraction robot base 311 so that the insertion and extraction robot 31 can move only along the row change track 352 without excessive swinging.

[0170] The row-changing synchronous belt assembly 353 includes a row-changing synchronous belt 3531 and a row-changing rotating wheel 3532. Synchronous teeth are disposed on both the outer wall of the row-changing rotating wheel 3532 and the inner side of the row-changing synchronous belt 3531 and are engaged with each other, so that the row-changing rotating wheel 3532 can drive the row-changing synchronous belt 3531. In addition, synchronizing teeth may also be disposed on both the outer side of the row-changing synchronous belt 3531 and the insertion and extraction robot base 311 and are engaged with each other, so that the row-changing synchronous belt 3531 can drive the insertion and extraction robot 31 to the row-changing robot 35.

[0171] The principle by which the queue change robot 35 transports the insertion and removal robots 31 is as follows.

[0172] The inserting and extracting robot synchronous belt 121 drives the inserting and extracting robot 31 to move upward along the inserting and extracting robot track 11. When the inserting and extracting robot moves to the row change robot 35, the inserting and extracting robot base 351 coincides with the row change track 352. The inserting and extracting robot synchronous belt 121 and the row change synchronous belt 3531 jointly drive the inserting and extracting robot 31 to continue moving upward until the inserting and extracting robot base 351 is separated from the inserting and extracting robot synchronous belt 121. Due to the limiting function of the outer synchronous teeth of the row change track 352 and the row change synchronous belt assembly 353, the inserting and extracting robot 31 may stay on the row change robot 35.

[0173] 10, the feed screw mechanism 13 includes a feed screw mechanism base 131, a transmission feed screw 132, a feed screw mechanism driving motor 133, and a fixed base 134. The transmission feed screw 132, the feed screw mechanism driving motor 133, and the fixed base 134 are all positioned on the feed screw mechanism base 131, the feed screw mechanism driving motor 133 drives the transmission feed screw 132 to rotate, and the fixed base 134 is provided with a nut structure that matches the transmission feed screw 132. When the transmission feed screw 132 rotates, the transmission feed screw 132 drives the fixed base 134 to perform linear motion in the horizontal direction.

[0174] As shown in FIG. 11a, the lead screw mechanism 13 and the row changing robot 35 may be located at the top of the dispensing section 1.

[0175] FIG. 11b is a schematic diagram of the queue changing robot 35 carrying the insertion and extraction robot 31.

[0176] (2) After the insertion and extraction robot 31 extracts and releases the optical fiber connector, the first fiber receiving mechanism 32 needs to receive the optical fiber connector and the optical fiber in the connector retraction portion 2 .

[0177] The first fiber receiving mechanism 32 will be described below.

[0178] As shown in Fig. 12, the first fiber accommodating mechanism 32 includes two fiber accommodating units 320, which are arranged opposite to each other. Each fiber accommodating unit 320 includes a rotating shaft 321 and a fiber accommodating wheel 322, the axial direction of the rotating shaft 321 is parallel to the arrangement direction of the connector accommodating holes 2111, the fiber accommodating wheel 322 is keyed to the rotating shaft 321, and the fiber accommodating wheel 322 is movable in the axial direction of the rotating shaft 321. The fiber accommodating wheel 322 is provided with a protrusion 3221 in the circumferential direction, and the position of the protrusion 3221 of the fiber accommodating wheel 322 of one fiber accommodating unit 320 corresponds to the position of the protrusion 3221 of the fiber accommodating wheel 322 of the other fiber accommodating unit 320. In the fiber accommodating state of the first fiber accommodating mechanism 32, the two protrusions 3221 clamp the optical fiber connected to the optical fiber connector and accommodate the optical fiber connected to the optical fiber connector by rotation.

[0179] In the present application, the driving method of the rotary shaft 322 is not specifically limited. For example, as shown in Fig. 12, the driving device of the rotary shaft includes a rotary shaft motor 323a, a rotary shaft driving gear 323b, and two rotary shaft driven gears 323c. The two rotary shaft driven gears 323c are sleeve-connected on the two rotary shafts 321, respectively, and engaged with each other. The rotary shaft driving gear 323b is engaged with one of the rotary shaft driven gears 323c, and is fixedly connected to the output shaft of the rotary shaft motor 323a.

[0180] The principle by which the driving device rotates the rotating shaft 322 is as follows.

[0181] The output shaft of the rotary shaft motor 323a rotates and drives the rotary shaft driving gear 323b, which rotates and drives one rotary shaft driven gear 323c engaged with the rotary shaft driving gear, and the rotary shaft driven gear 323c rotates and drives the other rotary shaft driven gear 323c. The two rotary shaft driven gears 323c rotate and drive the two rotary shafts 321, respectively. This driving method can ensure the synchronization of the rotation of the two rotary shafts 322. The above-mentioned driving device is merely an example of the present embodiment of the present application and does not limit the present application. For example, the driving device may instead include two driving motors, and the output shafts of the two driving motors are fixedly connected to the two rotary shafts 321, respectively.

[0182] In the present application, the driving method for moving the fiber-containing wheel 322 in the axial direction of the rotation shaft 321 is not specifically limited. For example, as shown in FIG. 14b, the clamp jaw robot 33 is provided with a clamp plate 336, which includes two clamp seats. The fiber-containing wheel 322 is positioned between the two clamp seats. In this manner, when the clamp jaw robot 33 moves, the fiber-containing wheel 322 is slidably driven along the rotation shaft 321. For the principle of the movement of the clamp jaw robot 33, please refer to the description of the clamp jaw robot 33.

[0183] The first fiber receiving mechanism 32 is positioned within the active fiber receiving area 22 of the optical fiber distribution device. For a specific location, see Figure 13. The first fiber receiving mechanism 32 is positioned below the connector receiving base 211.

[0184] The fiber-accommodating principle of the first fiber-accommodating mechanism 32 will be described below with reference to Figures 14a and 14b. In Figure 14a, the clamp plate 336 configured to drive the fiber-accommodating wheel 322 to move axially is hidden, and in Figure 14b, the clamp plate 336 configured to drive the fiber-accommodating wheel 322 to move axially is shown.

[0185] 14a, in the fiber-accommodating state of the first fiber accommodating mechanism 322, the protrusions 3221 of the two fiber accommodating wheels 322 clamp the optical fiber and rotate relatively in the direction of the arrow shown in the figure, so that the two fiber accommodating wheels 322 drive the optical fiber by friction to gradually accommodate it in the fiber storage area 23. In addition, the optical fiber connector is also gradually accommodated in the connector storage area 21 in conjunction with the optical fiber.

[0186] (3) After the first fiber receiving mechanism 32 receives the optical fiber and the optical fiber connector in the connector retraction portion 2, the clamp jaw robot 33 must remove the optical fiber connector and transfer the optical fiber connector to the insertion and extraction robot 31.

[0187] The clamp jaw robot 33 and associated components are described below.

[0188] 15a and 15b, the clamp jaw robot 33 includes a clamp jaw robot base 331, a laterally movable base 332, a clamp mechanism 333, a clamp jaw pair 334, and a clamp jaw rotation drive 335. The laterally movable base 332 is slidably connected to the clamp jaw robot base 331, and the sliding direction is perpendicular to the arrangement direction of the connector receiving holes 2111. The clamp jaw rotation drive 335 is fixed on the laterally movable base 332, and the clamp jaw pair 334 is sleeve-connected on the rotation shaft of the clamp jaw rotation drive 335. The clamp mechanism 333 is positioned on the laterally movable base 332 and is configured to tighten or loosen the clamp jaw pair 334.

[0189] The clamp jaw pair 334 can implement a clamping action, a loosening action, and a withdrawal action on the optical fiber connector. The clamp mechanism 333 can implement the clamping action and the loosening action of the clamp jaw pair 334 on the optical fiber connector by clamping or loosening the clamp jaw pair 334. The clamp jaw rotation drive device 335 can rotate the clamp jaw pair 334 to implement a withdrawal action on the optical fiber connector. After the clamp jaw pair 334 clamps the optical fiber connector, the clamp jaw rotation drive device 335 can rotate the clamp jaw pair 334 to withdraw the optical fiber connector from the connector receiving hole 2111.

[0190] In addition, to allow the clamp jaw robot 33 to avoid the optical fiber connector, the clamp mechanism 333, the clamp jaw pair 334, and the clamp jaw rotation drive 335 may all be fixed on a laterally movable base 332, which is slidably connected to the clamp jaw robot base 331, with the sliding direction (z direction shown in FIG. 15b) perpendicular to the arrangement direction of the connector receiving holes 2111. In this way, the clamp jaw pair 334 can move closer to or away from the optical fiber connector.

[0191] In the present application, the driving method of the laterally movable base 332 is not specifically limited. For example, as shown in FIG. 15b, the driving device of the laterally movable base 332 includes a laterally movable base driving motor 332a and a laterally movable base driving gear 332b. The laterally movable base driving gear 332b is fixedly connected to the rotation shaft of the laterally movable base driving motor 332a and engaged with the laterally movable base 332 (the laterally movable base 332 is provided with a rack structure). When driving the laterally movable base 332 to move horizontally, the output shaft of the laterally movable base driving motor 332a rotates and drives the laterally movable base driving gear 332b, which then drives the laterally movable base 332 to perform linear motion.

[0192] There can be multiple implementations of the clamping mechanism 333, and the following provides one possible implementation.

[0193] As shown in FIG. 16, the clamp mechanism 333 includes a clamp driver 3330, a drive connecting rod 3331, and two clamp arms 3332. The middle parts of the two clamp arms 3332 are hinged, and the hinge points are fixed. The clamp arms 3332 are provided with connecting protrusions 33321, and the drive connecting rod 3331 is provided with connecting holes 33311 at both ends of the drive connecting rod 3331. The connecting protrusions 33321 of the two clamp arms 3332 are respectively positioned in the connecting holes 33311 at both ends of the drive connecting rod 3331, and the connecting protrusions 33321 are slidable in the connecting holes 33311. Each clamp end of the two clamp arms 3332 clamps one clamp jaw of the clamp jaw pair 334. The push rod of the clamp driver 3330 is fixedly connected to the drive connecting rod 3331, and the push rod is perpendicular to the drive connecting rod 3331.

[0194] The clamping and loosening principles of the clamping mechanism 333 are as follows.

[0195] During clamping, the push rod of the clamp driver 3330 extends outward, driving the drive connecting rod 3331 to move, so that the two clamp arms 3332 move towards each other under the pressure of the drive connecting rod 3331, and the two clamp arms 3332 drive the clamp jaw pair 334 to implement a clamping operation. During loosening, the push rod of the clamp driver 3330 retracts inward, driving the drive connecting rod 3331 to move, so that the two clamp arms 3332 move away from each other under the drive of the drive connecting rod 3331, and the two clamp arms 3332 drive the clamp jaw pair 334 to implement a loosening operation.

[0196] 16 , in order to make the clamp mechanism 333 more stable, the clamp mechanism 333 may further include a follow-up connecting rod 3333. Each clamp arm 3332 is provided with two connecting protrusions 33321, and the other two connecting protrusions 33321 of the two clamp arms 3332 are positioned in two follow-up connecting holes 33331 of the follow-up connecting rod 3333.

[0197] The clamp jaw robot 33 may move within the connector yard 21 so that the clamp jaw robot 33 can handle the insertion and extraction of more fiber optic connectors. The following provides one possible implementation of the clamp jaw robot 33.

[0198] 17, the connector storage area 21 is provided with a clamp jaw robot guide rail 214 and a clamp jaw robot synchronous belt assembly 215. The axial direction of the clamp jaw robot guide rail 214 and the movement direction of the clamp jaw robot synchronous belt assembly 215 are parallel to the arrangement direction (x direction) of the connector accommodating holes 2111. The clamp jaw robot base 331 coincides with the clamp jaw robot guide rail 214 and is fixedly connected to the clamp jaw robot synchronous belt assembly 215.

[0199] The clamp jaw robot guide rail 214 coincides with the clamp jaw robot base 331 of the clamp jaw robot 33 to form a linear motion pair. The clamp jaw robot guide rail 214 can restrict the clamp jaw robot base 331 such that the clamp jaw robot 33 can only move along the clamp jaw robot guide rail 214 and cannot be separated from the clamp jaw robot guide rail 214. Power for the clamp jaw robot 33 to move may be provided by a clamp jaw robot synchronous belt assembly 215.

[0200] The clamp jaw robot synchronous belt assembly 215 includes a clamp jaw robot synchronous belt 2151 and a clamp jaw robot rotating wheel 2152. Synchronous teeth are arranged on both the outer wall of the clamp jaw robot rotating wheel 2152 and the inner side of the clamp jaw robot synchronous belt 2151 and are engaged with each other, so that the clamp jaw robot rotating wheel 2152 can rotate and drive the clamp jaw robot synchronous belt 2151. In addition, the outer side of the clamp jaw robot synchronous belt 2151 can be fixedly connected to the clamp jaw robot base 331, and the clamp jaw robot synchronous belt 2151 can drive and move the clamp jaw robot 33. In another possible implementation, the outer side of the clamp jaw robot synchronous belt 2151 can be further engaged with the clamp jaw robot base 331.

[0201] 15b, the clamp jaw robot 33 further includes a clamp plate 336, which corresponds to the position of the clamp jaw pair 334 in the vertical direction (y direction), and the clamp plate 336 is fixedly connected to the clamp jaw robot base 331. The clamp plate 336 clamps the fiber-storing wheel 322 in the first fiber-storing mechanism 32, so that when the clamp jaw robot 33 moves, the clamp plate 336 can drive the fiber-storing wheel 322 to move.

[0202] Since the clamp plate 336 corresponds to the position of the clamp jaw pair 334 in the vertical direction (y direction), when the first fiber accommodating mechanism 32 accommodates the optical fiber connector in the connector accommodating hole 2111, the clamp jaw robot 33 does not need to move and can directly clamp the optical fiber connector by using the clamp jaw pair 334.

[0203] In one possible implementation, the clamping jaw robot 33 may transfer the extracted fiber optic connector directly to the insertion and extraction robot 31 .

[0204] In another possible implementation, the clamp jaw robot 33 may indirectly transfer the extracted optical fiber connector to the insertion and extraction robot 31, for example, the extracted optical fiber connector may be transferred by using a transport robot 34. In this case, the robot system 3 further includes the transport robot 34. The transport robot 34 is positioned in the junction area between the distribution section 1 and the connector repository 21 (for example, it may be positioned on the distribution section 1 or may be positioned in the connector repository 21, but this application is not limited thereto), and is configured to transfer the connector carried by the clamp jaw robot 33 to the insertion and extraction robot 31.

[0205] 18a and 18b, the transport robot 34 includes a transport robot base 341, a tipping drive unit 342, and a tipping plate 343. The tipping drive unit 342 is fixed on the transport robot base 341, and the tipping drive unit 342 is power-transmittingly connected to the tipping plate 343. A connector carrying hole 3431 is provided on the surface of the tipping plate 343 adjacent to the connector retraction unit 2, and an optical fiber connector is attached to the connector carrying hole 3431.

[0206] As shown in FIG. 18c, the rollover drive device 342 includes a rollover drive motor 3421, a rollover drive gear 3422, and a rollover driven gear 3423. The rollover drive gear 3422 is sleeve-connected on the output shaft of the rollover drive motor 3421, the rollover drive gear 3422 is engaged with the rollover driven gear 3423, and one side of the rollover plate 343 is fixedly connected to the rollover driven gear 3423. In this case, the rollover drive motor 3421 uses the rollover drive gear 3422 to rotate the rollover driven gear 3423, and the rollover plate 343 rotates together with the rollover driven gear 3423, and the rollover plate 343 rolls over.

[0207] The roll plate 343 has a first roll state (as shown in FIG. 18a) and a second roll state (as shown in FIG. 18b).

[0208] In the first rollover state, the rollover plate 343 is in a horizontal or substantially horizontal state and is configured to receive the optical fiber connector carried by the clamp jaw robot 33. For example, the clamp jaw robot 33 clamps the optical fiber connector by using the clamp jaw pair 334 and inserts the optical fiber connector into the connector carrying hole 3431 by rotating.

[0209] In the second roll position, the roll plate 343 is in a vertical or near vertical position and is configured for the insertion and extraction robot 31 to extract the fiber optic connector from the connector delivery hole 3431 .

[0210] In one possible implementation, the transport robot base 341 may be fixed to the connector yard 21. The length of the tipping plate 343 is large so that the tipping plate can cover multiple rows of clamp jaw robot 31 positions.

[0211] In another possible implementation, the transport robot 34 may further move within the connector storage 21. As shown in Fig. 19, the connector storage 21 is provided with a transport robot track 212 and a transport robot synchronous belt assembly 213. The axial direction of the transport robot track 212 is perpendicular to the arrangement direction of the connector receiving holes 2111 (i.e., the z direction in Fig. 19), the transport robot track is positioned on one side of the connector storage 21, and the transport robot synchronous belt assembly 213 is positioned inside the transport robot track 212. The transport robot base 341 coincides with the transport robot track 212 and is fixedly connected to the transport robot synchronous belt assembly 213.

[0212] The transport robot track 212 aligns with the insertion and extraction robot base 311 of the transport robot 34 to form a linear pair. The transport robot track 212 can constrain the insertion and extraction robot base 311 such that the transport robot 34 can only move along the transport robot track 212 and cannot become separated from the transport robot track 212. Power for the transport robot 34 to move may be provided by a transport robot synchronous belt assembly 213.

[0213] The transport robot synchronous belt assembly 213 includes a transport robot synchronous belt 2131 and a transport robot rotating wheel 2132. Synchronous teeth are arranged on both the outer wall of the transport robot rotating wheel 2132 and the inner side of the transport robot synchronous belt 2131 and are engaged with each other, so that the transport robot rotating wheel 2132 can rotate and drive the transport robot synchronous belt 2131. In addition, the outer side of the transport robot synchronous belt 2131 can be fixedly connected to the transport robot base 314, and the transport robot synchronous belt 2131 can drive and move the transport robot 34. In another possible implementation, the outer side of the transport robot synchronous belt 2131 can be further engaged with the transport robot base 314.

[0214] (4) After receiving the target optical fiber connector, the insertion and extraction robot 31 may insert the optical fiber connector into the target optical fiber adapter. For the content of this part, please refer to the relevant description in (1). The details will not be described again here.

[0215] Based on the above, the optical fiber scheduling process has been fully described with reference to the optical fiber distribution devices shown in Figures 1 to 19.

[0216] Stage 1: A controller in a fiber optic scheduling device receives an instruction to insert a target fiber optic connector into a target fiber optic adapter.

[0217] Second stage: the controller obtains the position of the initial optical fiber adapter into which the target optical fiber connector is inserted according to the connected optical fiber of the optical fiber connector previously stored. In this case, the position of the target optical fiber adapter may be further obtained.

[0218] Third stage: The controller controls the insertion and extraction robot synchronous belt assembly 12, the row change robot 35, and the lead screw mechanism 13 to move the insertion and extraction robot 31 close to the initial fiber optic adapter.

[0219] Step 4: Control the insertion and extraction robot 31 to extract the target fiber optic connector from the initial fiber optic adapter and release the target fiber optic connector.

[0220] Fifth step: The clamp jaw robot 33 is controlled to move the first fiber-receiving mechanism 32 close to the optical fiber receiving hole 2111 corresponding to the target optical fiber connector.

[0221] Sixth step: The first fiber accommodating mechanism 32 is controlled to gradually accommodate the target optical fiber connector into the optical fiber accommodating hole 2111. In this process, it may further be detected in real time whether the accommodation is completed.

[0222] Seventh step: The clamp jaw robot 33 is controlled to clamp the target optical fiber connector.

[0223] Step 8: The clamp jaw robot 33 is moved close to the transport robot 34 by controlling the clamp jaw robot synchronous belt assembly 215.

[0224] Ninth step: The clamp jaw robot 33 is controlled to insert the target optical fiber connector into the connector carrying hole 3431 of the transport robot 34.

[0225] Step 10: The transport robot 34 is controlled to turn the tipping plate 343 over to the vertical position.

[0226] Step 11: The insertion and extraction robot 31 is controlled to clamp the target optical fiber connector from the transport robot 34.

[0227] Step 12: Insertion and Extraction Robot Synchronous belt assembly 12, row change robot 35, and lead screw mechanism 13 are controlled to move the insertion and extraction robot 31 close to the target fiber optic adapter.

[0228] Step 13: Control the insertion and extraction robot 31 to insert the target fiber optic connector into the target fiber optic adapter.

[0229] Another optical fiber distribution device provided in an embodiment of the present application will now be described with reference to Figures 20 to 22c.

[0230] As shown in FIG. 20, the distribution section 1 of the optical fiber distribution device and the connector lead-in panel (that is, the connector storage area 21) are disposed opposite to each other.

[0231] As shown in FIG. 21, the connector receptacle 2 may be divided into three areas in the optical fiber direction: a connector placement area 21, an active fiber accommodating area 22, and a fiber storage area 23, with the connector placement area 21 being adjacent to the optical fiber connector.

[0232] The connector storage 21 is used for storing optical fiber connectors, and the connector storage 21 is provided with a plurality of connector receiving holes. Each connector receiving hole is configured to receive an optical fiber connector, and an optical fiber connected to the optical fiber connector passes through the connector receiving hole. In one possible implementation, to facilitate receiving the optical fiber connector, the connector receiving hole may be a stepped hole, and the optical fiber connector may be placed on a stepped base of the stepped hole.

[0233] A mechanism capable of receiving an optical fiber is provided in the active fiber receiving area 22. The fiber receiving principle of this mechanism may be to receive the optical fiber connector in the connector storage area 21 by dragging the optical fiber of the optical fiber connector, and to receive the optical fiber in the fiber storage area 23.

[0234] The fiber storage area 23 is used to store optical fibers connected to the optical fiber connector. To prevent the stored optical fibers from wrapping, the fiber storage area 23 may be provided with a plurality of fiber storage cavities spaced apart from one another, each fiber storage cavity configured to accommodate one optical fiber. In addition, the plurality of fiber storage cavities correspond one-to-one to the plurality of connector receiving holes.

[0235] 20 , the robot system 3 includes a distribution robot 36 and a second fiber accommodating mechanism 37. The distribution robot 36 is positioned between the distribution unit 1 and the connector retraction unit 2, and is configured to insert and remove optical fiber connectors from optical fiber adapters, and to remove the optical fiber connectors from the connector retraction unit 2. The second fiber accommodating mechanism 37 is positioned above the connector retraction unit 2, and is configured to retract the optical fiber connectors and the optical fibers connected to the optical fiber connectors into the connector retraction unit 2.

[0236] In the following, the distribution robot 36 and the second fiber accommodating mechanism 37 will be described in detail according to the work sequence of the robots in the optical fiber scheduling process.

[0237] (1) First, the distribution robot 36 must unplug the target fiber optic connector from the initial fiber optic adapter and release the target fiber optic connector.

[0238] As shown in Fig. 22a, the dispensing robot 36 includes a first guide rail 361, a second guide rail 362, a third guide rail 363, and a clamping mechanism 364. The first guide rail 361 is fixed to the bottom of the optical fiber dispensing device, the second guide rail 362 is slidably connected to the first guide rail 361, and the third guide rail 363 is fixed on the second guide rail 362, and the axial directions of the first guide rail 361, the second guide rail 362, and the third guide rail 363 are perpendicular to each other. The clamping mechanism 364 is slidably connected to the third guide rail 363 and configured to clamp and loosen the optical fiber connector.

[0239] A drive system for moving the clamp mechanism 364 along the first guide rail 361, the second guide rail 362, and the third guide rail 363 will be described below.

[0240] As shown in FIG. 22b, the second guide rail 362, the third guide rail 363, and the clamp mechanism 364 are all positioned on the first guide rail 361. The arrangement direction of the first guide rail 361 is the z-direction. The clamp mechanism 364 may move between the distribution unit 1 and the connector storage area 21 by moving along the first guide rail 361. The drive device includes a first motor 361a and a first synchronous belt 361b. The first motor 361a rotates and drives the first synchronous belt 361b, and the first synchronous belt 361b is transmission-connected (e.g., fixedly connected or engaged) to the second guide rail 362. In this case, the first motor 361a can drive the second guide rail 362 to move along the first guide rail 361, and the third guide rail 363 and the clamp mechanism 364 are positioned on the second guide rail 362 and move along the second guide rail 362.

[0241] The third guide rail 363 and the clamp mechanism 364 are positioned on the second guide rail 362, and the arrangement direction of the second guide rail 362 is the x-direction. The third guide rail and the clamp mechanism may move in the x-direction toward the target optical fiber connector by moving along the second guide rail 362. The driving device includes a second motor 362a and a second synchronous belt 362b. The second motor 362a rotates and drives the second synchronous belt 362b, and the second synchronous belt 362b is in transmission connection (e.g., fixedly connected or engaged) with the third guide rail 363. In this case, the second motor 362a can drive the third guide rail 363 to move along the second guide rail 362, and the clamp mechanism 364 moves along the third guide rail 363.

[0242] The clamp mechanism 364 is positioned on the third guide rail 363, and the arrangement direction of the third guide rail 363 is the y direction. The clamp mechanism may move along the third guide rail 363 in the y direction toward the target optical fiber connector and avoid the optical fiber. The driving device may include a third motor 363a and a third feed screw 363b. The third motor 363a is transmission-connected to the third feed screw 363b, and the clamp mechanism 364 coincides with the third feed screw 363b (the clamp mechanism 364 is provided with a nut structure). In this case, the third motor 363a rotates and drives the third feed screw 363b, and the clamp mechanism 364 moves along the third guide rail 363.

[0243] It can be seen that the distribution robot 36 provided in this embodiment of the present application actually has a three-axis robot structure and can move in the x-, y-, and z-directions. The distribution robot 36 may move to the distribution section 1 and the connector storage area 21 by moving in the z-direction, and perform position switching between the distribution section and the connector storage area. The distribution robot 36 may move to the target connector by moving in the x- and z-directions, and may avoid the optical fiber by moving in the y-direction.

[0244] The clamp mechanism 364 may have a number of possible implementations, which are not specifically limited in the present embodiment of the present application, and one possible implementation is provided below.

[0245] 22c, the clamp mechanism 364 includes a first clamp arm 3641, a second clamp arm 3642, and a clamp driver 3643. The first clamp arm 3641 is slidably connected to the second clamp arm 3642. The clamp driver 3643 is operably connected to the first clamp arm 3641 and configured to drive the clamp end of the first clamp arm 3641 away from or towards the clamp end of the second clamp arm 3642.

[0246] The clamp driver 3643 may implement the clamping and loosening actions of the first clamp arm 3641 and the second clamp arm 3642 by pushing the first clamp arm 3641 .

[0247] (2) After the distribution robot 36 removes and releases the optical fiber connector, the second fiber accommodating mechanism 37 must accommodate the optical fiber connector and the optical fiber in the connector retraction portion 2 .

[0248] For the relevant description of the second fiber accommodating mechanism 37 provided in this embodiment of the present application, please refer to the relevant description of the first fiber accommodating mechanism 32. The fiber accommodating principle of the second fiber accommodating mechanism and the first fiber accommodating mechanism is the same.

[0249] 23, the second fiber accommodating mechanism 37 also includes two fiber accommodating units, which are arranged opposite to each other. Each fiber accommodating unit includes a second rotating shaft 371 and a second fiber accommodating wheel 372, the axial direction of the second rotating shaft 371 is parallel to the arrangement direction of the connector accommodating holes, the second fiber accommodating wheel 372 is keyed to the second rotating shaft 371, and the second fiber accommodating wheel 372 is movable in the axial direction of the second rotating shaft 371. The second fiber accommodating wheel 372 is provided with a protrusion in the circumferential direction, and the position of the protrusion of the second fiber accommodating wheel 372 of one fiber accommodating unit corresponds to the position of the protrusion of the second fiber accommodating wheel 372 of the other fiber accommodating unit. In the fiber accommodating state of the second fiber accommodating mechanism 37, the two protrusions clamp the optical fiber connected to the optical fiber connector and accommodate the optical fiber connected to the optical fiber connector by rotation.

[0250] It should be noted that the second fiber-accommodating wheel 372 in the second fiber-accommodating mechanism 37 does not need to be equipped with a dedicated drive, and the drive may drive the second fiber-accommodating wheel 372 to move axially along the second rotation axis 371. The drive may be similar to that of the clamp jaw robot 33, and both are driven by a synchronous belt.

[0251] (3) After the second fiber accommodating mechanism 37 accommodates the optical fiber and the optical fiber connector in the connector retracting section 2, the distribution robot 36 needs to take out the optical fiber connector and insert the optical fiber connector into the target optical fiber adapter. For this process, please refer to the relevant description in (1). Details will not be described again here.

[0252] Based on the above, the optical fiber scheduling process has been fully described with reference to the optical fiber distribution devices shown in Figures 20 to 22c.

[0253] Stage 1: A controller in a fiber optic scheduling device receives an instruction to insert a target fiber optic connector into a target fiber optic adapter.

[0254] Second stage: the controller obtains the position of the initial optical fiber adapter into which the target optical fiber connector is inserted according to the connected optical fiber of the optical fiber connector previously stored. In this case, the position of the target optical fiber adapter may be further obtained.

[0255] Third step: The controller controls the dispensing robot 36 to move close to the initial fiber optic adapter, pick up the target fiber optic connector, and release it.

[0256] Fourth stage: The controller controls the second fiber receiving mechanism 37 to gradually receive the target optical fiber connector into the optical fiber receiving hole. In this process, it may further detect in real time whether the receiving is completed.

[0257] Fifth step: The controller controls the distribution robot 36 to move from the distribution section 1 to the connector lead-in section 2, move close to the optical fiber receiving hole corresponding to the target optical fiber connector, and clamp the target optical fiber connector. The distribution robot transports the target optical fiber connector, moves from the connector lead-in section 2 to the distribution section 1, moves close to the target optical fiber adapter, and inserts the target optical fiber connector into the target optical fiber adapter.

[0258] An embodiment of the present application further provides an optical fiber scheduling method. As shown in Figure 24, the method is applied to an optical fiber distribution device, and the method includes the following steps:
