[0032] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The utility model proposes a fiber jumper device, which includes a box 1, an internal fiber pigtail and a mechanical arm 2. The box 1 is used to hold the internal fiber pigtail and the mechanical arm 2, so that the mechanical arm 2 can be used to adjust the connection relationship of the internal fiber pigtail, thereby achieving the purpose of automatic fiber jumper.

[0034] The box body 1 has a first side panel 11 and a second side panel 12. In a specific implementation, the first side panel 11 and the second side panel 12 may constitute two side walls of the box body 1, such as two opposite side walls or two adjacent side walls. In other implementations, the first side panel 11 and the second side panel 12 may also be formed on the same side of the box body 1.

[0035] Specifically, the first side plate 11 is provided with a plurality of first access ports 111, and the second side plate 12 is provided with a plurality of second access ports 121. Specifically, the first access ports 111 and the second access ports 121 are both optical fiber interfaces, respectively used for optical fibers to be jumpered.

[0036] Internal pigtails, multiple internal pigtails are arranged in the box 1, one end of the internal pigtail is connected to the first access port 111, and the other end is used to connect to the corresponding second access port 121. The internal pigtail is used to connect the first access port 111 and the second access port 121 respectively, and the corresponding relationship between the first access port 111 of the internal pigtail and different second access ports 121 is changed to achieve fiber jumper.

[0037] The robot arm 2 is installed in the box 1 and is used to insert the end of the internal pigtail into the corresponding first access port 111 or the second access port 121 .

[0038] During specific use, the first access port 111 and the second access port 121 are first connected to the corresponding external optical fibers respectively. During specific implementation, the external optical fibers can be connected to the first access port 111 and the second access port 121 in a specific corresponding relationship as needed. For example, multiple first access ports 111 and second access ports 121 can be numbered in turn, and the external optical fibers can be connected to the first access port 111 and the second access port 121 respectively according to the corresponding relationship of the numbers.

[0039] Specifically, in order to realize the connection between the internal pigtail and each first access port 111, and the connection between the internal pigtail and each second access port 121, in the present embodiment, a moving component 3 is further included, and the moving component 3 is arranged in the box body 1, and the robot arm 2 is connected to the moving component 3 so that the robot arm 2 can move in the box body 1. The moving component 3 is used to drive the robot arm 2 to move, so as to facilitate the connection between different first access ports 111 and different second access ports 121 and the internal pigtail. In the specific implementation, a plurality of first access ports 111 are arranged along the moving direction of the robot arm 2, and a plurality of second access ports 121 are also arranged along the moving direction of the robot arm 2. In this way, the robot arm 2 is driven by the moving component 3 to move to the first access port 111 or the second access port 121 that needs to be plugged in and out, so as to facilitate the plugging and unplugging operation of the robot arm 2.

[0040] In the specific implementation, the movement of the mobile component 3 and the plugging and unplugging of the mechanical arm 2 are controlled by the control unit, which includes a communication module, a microcontroller, etc. Through the communication module, it is possible to use the network to transmit the fiber jumper instruction, thereby achieving the purpose of remote control of the fiber jumper. The driving power supply of the mobile component 3 and the mechanical arm 2 can be a 12-24V lithium battery, which can be an external battery or a corresponding built-in lithium battery to provide power for the entire device.

[0041] In the specific implementation, in order to prevent the end of the internal pigtail from being contaminated by dust, the present embodiment has also made the following improvements. Specifically, a plurality of first protective covers 112 are provided on the inner side of the first side panel 11, and one end of the internal pigtail used for connecting with the first access port 111 can be inserted into the first protective cover 112. When fiber jumper is not required, that is, when no external optical fiber is inserted into the first access port 111, if the internal pigtail is inserted into the first access port 111, it is easy to cause the corresponding end of the internal pigtail to be contaminated by dust. By inserting the corresponding end of the internal pigtail into the corresponding first protective cover 112, it is possible to prevent the end of the internal pigtail from being contaminated by dust.

[0042] A plurality of second protective covers 122 are provided on the inner side of the second side panel 12, and one end of the internal pigtail for connecting with the second access port 121 can be inserted into the second protective cover 122. Similarly, when fiber jumper is not required, that is, when no external optical fiber is inserted into the second access port 121, if the internal pigtail is inserted into the second access port 121, the corresponding end of the internal pigtail is easily contaminated by dust. By inserting the corresponding end of the internal pigtail into the corresponding second protective cover 122, the end of the internal pigtail can be prevented from being contaminated by dust.

[0043] In a specific implementation, in order to facilitate the plugging and unplugging of the internal pigtail between the first access port 111 and the second access port 121 by using a mechanical arm 2, the first side panel 11 and the second side panel 12 are located on opposite sides of the box body 1, and the moving component 3 is located between the first side panel 11 and the second side panel 12. When in use, the first access port 111 and the second access port 121 are distributed on both sides of the moving component 3. In a specific implementation, in order to facilitate the plugging and unplugging of the internal pigtail, a clamping mechanism can be provided at the end of the mechanical arm 2.

[0044] In a preferred implementation, the moving assembly 3 includes a moving synchronous belt, and the robot arm 2 is fixedly mounted on the moving synchronous belt. In other implementations, the movement of the robot arm 2 can also be achieved by other means, such as a ball screw, a worm gear, a gear rack, or a slide rail. Compared with other methods, the moving synchronous belt is more stable, and the precision of the moving synchronous belt can be improved by accurately controlling the drive motor to achieve high-precision position control.

[0045] When a mobile synchronous belt is used as a transmission mechanism, pulleys are also included, one of which is connected to a drive motor. This driving method has the advantages of smooth transmission and low noise. By selecting a suitable pulley diameter and synchronous belt length, a wide range of speed regulation and precise positioning can be achieved. Similarly, using a servo motor or a stepper motor as a drive motor can provide sufficient torque and control accuracy. In order to improve the flexibility and scalability of the design, a modular design concept can be adopted. Different types of mobile mechanisms are used as independent modules and combined and spliced ​​according to actual needs. This not only reduces the complexity of the design, but also makes it easy to maintain and upgrade the system. The robot arm 2 and the mobile component 3 together constitute a fiber adjustment unit.

[0046] In some implementations, in order to realize intelligent fiber jumper, the robot arm 2 includes a multi-section rotating mechanism 21, a clamping mechanism 22, a sensor and a visual system 23, a control system, a human-machine interface, maintainability and reliability, compatibility and extensibility, etc. The multi-section rotating mechanism 21 is connected in sequence, and one end is fixedly connected to the moving component 3, and the other end is connected to the clamping mechanism 22. The two adjacent sections of the rotating mechanism 21 can rotate relative to each other to realize multi-degree-of-freedom motion. The clamping and release of the clamping mechanism 22 are controlled by the control system. The sensor and the visual system 23 are arranged at the free end of the robot arm 2, that is, the end where the rotating mechanism 21 is connected to the clamping mechanism 22. The positions of the first access port 111, the second access port 121, the first protective cover 112 and the second protective cover 122 are identified by the sensor and the visual system 23, and then the corresponding insertion or removal operation is performed by the control system. For the operation and control of the robot arm 2, those skilled in the art can realize it, and will not be repeated here.

[0047] Through a reasonable design scheme, the robot can realize the functions of precise plugging and unplugging and arranging optical fibers, and improve production efficiency and product quality. Specifically, the position of the end of the internal pigtail, the position of the first access port 111, the position of the second access port 121, the position of the first protective cover 112 and the position of the second protective cover 122 are accurately identified through the visual system. For the main structure, a main structure with good rigidity and strong stability is designed as the basis of the robot. This can be achieved by using high-strength materials and reasonable structural layout; for the multi-section rotating mechanism, a multi-section rotating mechanism is designed to adjust the robot's posture and the extension distance in the Y and Z directions so that it can smoothly insert or pull out the optical fiber. This can be achieved by using a rotary servo motor or a stepper motor; for the clamping mechanism, a reliable clamping mechanism can be designed to firmly clamp the optical fiber to ensure that the optical fiber is not damaged during the plugging and unplugging process; this can be achieved by using pneumatic or electric clamps. For sensors and visual systems: integrate advanced sensors and visual systems to identify the position and status of the optical fiber port. Inductive sensors can detect the position of the core docking device, thereby providing feedback signals to adjust the movement of the manipulator; for the control system, a centrally controlled electronic system can be designed to coordinate the movement of each component, which can be achieved by using PLC and controllers; for the human-computer interaction interface, an intuitive and easy-to-use human-computer interaction interface can be designed so that operators can easily set parameters, start programs and monitor operating status, which can be achieved by using APP or remote control software. In order to adapt to different working environments and task requirements, the robot should have good compatibility and scalability. This can be achieved through the use of universal interfaces, programmable software and flexible structural design. For details, please refer to Figure 4The controller includes a communication unit, a power supply unit and a control unit; the communication unit is connected to the control unit for communication, the power supply unit is electrically connected to the control unit, the control unit is electrically connected to the fiber modulation unit, and the control unit controls the fiber modulation unit to adjust according to the signal received by the communication unit to realize fiber jump. Those skilled in the art can realize this, and will not be described in detail here.

[0048] In order to make the internal pigtails neatly located in the box 1, in this embodiment, a fiber coiling body 4 is further included in the box 1, and the fiber coiling body 4 is used to coil the internal pigtails. In a specific implementation, the middle part of the internal pigtail is coiled on the fiber coiling body 4, and the end part can be inserted into the first access port 111, the second access port 121, the first protective cover 112 or the second protective cover 122.

[0049] In order to accurately identify the internal pigtail each time it is inserted or pulled out, the following improvements are made in this specific implementation. Specifically, both ends of the internal pigtail are provided with electronic tags; the end of the mechanical arm 2 is provided with a reader for identifying the electronic tag. That is, the corresponding end of the internal pigtail is identified by the reader provided at the end of the mechanical arm 2, so as to achieve the purpose of identifying the internal pigtail, so as to accurately identify the corresponding internal pigtail before each insertion or removal operation. In the specific implementation, the electronic tag is a passive RFID tag.

[0050] In a specific implementation, the first side panel 11 and the second side panel 12 are both detachably connected to the box body 1 .

[0051] In a specific implementation, in order to ensure sufficient interfaces for fiber jumpering, the number of the internal pigtails is not less than 10, and the number of the first access ports 111 and the number of the second access ports 121 are not less than the number of the internal pigtails. In one implementation, the number of the internal pigtails is 12, the number of the first access ports 111 and the number of the second access ports 121 are also 12, and accordingly, the number of the first protective cover 112 and the second protective cover 122 is also 12.

[0052] For specific implementation, please refer to Figure 5 The process of fiber jumper implemented by this device is as follows:

[0053] Step 1: Issue the command. When the fiber core No. 1 at the entrance of a certain optical cross-connect box A needs to be jumpered to the fiber core No. 3 at the exit, that is, the fiber core No. 1 on the left side of the optical cross-connect box A needs to be jumpered to the fiber core No. 3 on the right side, the fiber detection command that requires jumpering is issued through the operation and maintenance server or APP.

[0054] Step 2: The device receives the command and starts moving. The communication unit of the device is transmitted through the Internet of Things, and under the command of the control unit, the moving component 3 is started to move the mechanical arm 2 to the No. 1 pigtail on the first side plate 11 designated inside.

[0055] Step 3: Locate the connector. When the intelligent fiber jumper robot arm is lifted to the internal No. 1 pigtail head, the RFID tag can be attached to the optical fiber connector. When the connector enters the reading range of the sensor, the RFID reader can capture the tag information, including the connector's identity and preset location information.

[0056] Step 4: Implementation of the plugging and unplugging action. The clamping mechanism first clamps the No. 1 pigtail head, presses down the pigtail buckle, and at the same time the arm moves horizontally to retract, so as to pull out the front-side pigtail plug, and the mobile platform moves to the No. 1 first access port 111 of the first side panel 11 where the fiber jumper is required, and inserts the No. 1 internal pigtail. In the specific implementation, it can also be an internal pigtail of other numbers. The clamping mechanism clamps and releases the pigtail plug buckle, and the intelligent fiber jumper robot arm retracts it.

[0057] Step 5: After completing the action, the intelligent fiber jumper robot is moved to rotate in the opposite direction and first moves under the No. 1 internal pigtail of the second side plate 12.

[0058] Step 6: Positioning the connector: The intelligent fiber jumper robot arm is lifted to the No. 1 pigtail head of the second inner side plate 12 .

[0059] Step 7: Implementation of the plugging and unplugging action. The clamping mechanism first clamps the No. 1 pigtail head at the second side plate 12, presses down the pigtail buckle, and at the same time, the intelligent fiber jumper robot arm moves horizontally to retract, so as to pull out the No. 1 pigtail plug of the second side plate 12, and the robot arm moves to the No. 3 interface of the second side plate 12 where the fiber jumper is required, inserts the other end of the No. 1 internal pigtail, and the clamping mechanism releases the pigtail plug buckle, and the intelligent fiber jumper robot arm retracts.

[0060] That is, through the above second to seventh steps, the two ends of one of the internal pigtails are respectively inserted into the first access port 111 corresponding to the fiber core No. 1 of the optical cross box A entrance and the second access port 121 corresponding to the fiber core No. 3 of the optical cross box A exit, thereby realizing automatic fiber jumping.

[0061] To ensure accurate moving position, first of all, the encoder needs to be used with the stepper motor. The stepper motor is an actuator, and the encoder belongs to the feedback system. In order to ensure the accuracy of the running position, we calculate the number of pulses required for the stepper motor to feed in advance, and then use PLC programming to run so many pulses, the stepper motor stops, and the encoder feeds back the motor position at this time, forming a semi-closed loop control. Secondly, the inductive sensor can work in conjunction with the RFID tag to provide accurate positioning for the intelligent fiber jumper robot and achieve precise position docking of the fiber core.

[0062] The utility model has at least the following advantages:

[0063] 1. Improve operation and maintenance efficiency: The intelligent fiber jumper can quickly and accurately complete the plugging and unplugging and sorting of optical fibers in an automated manner, greatly improving the operation and maintenance efficiency of the optical fiber network. This can save a lot of manpower and time costs for data centers or communication operators that need to handle a large number of optical fiber connections.

[0064] 2. Reduce human errors: Traditional fiber patching relies on manual operation, which is prone to errors or improper operation. The intelligent fiber patching device can effectively reduce the occurrence of human errors and improve the accuracy and reliability of fiber optic connections through precise mechanical control.

[0065] 3. Optimize space utilization: Intelligent fiber jumper devices are usually designed with optimized space utilization solutions, which can achieve efficient fiber jumper management in a limited space, making the cable layout more beautiful and neat, and also convenient for future maintenance and management.

[0066] 4. Easy to locate faults: Standardized fiber jumpers are not only conducive to daily management, but also can quickly locate the problem when a fault occurs, speed up fault recovery, and reduce service interruption time caused by the fault.

[0067] 5. Improve service quality: The use of intelligent fiber jumper devices can improve the stability of the entire network and the quality of service, which is directly related to user experience and corporate reputation.

[0068] 6. Reduce long-term costs: Although the initial investment may be high, the intelligent fiber jumper device can save the company a lot of operating costs in the long run by improving work efficiency and reducing maintenance costs.

[0069] 7. Adapt to future development: With the rapid development of optical fiber networks, the requirements for fiber patching management are getting higher and higher. Intelligent fiber patching devices can adapt to the development of future technologies and provide companies with sustainable development solutions.

The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings.
