Referring to fig. 7, the control box 6 includes a central processing module, and further includes a power module, a communication interface module and a control card module connected to the central processing module, the power module is configured to supply power to the control box 6, the communication interface module is configured to connect the control box 6 to an upper computer to implement remote control, and the X-axis drive motor 506, the Y-axis drive motor 502, the Z-axis drive motor 510 and the electromagnet 5139 are all connected to the control card module and controlled by the control card module.

The communication module in this embodiment is an ethernet communication module, and an RJ45 interface is provided on the box body 1 for plugging a network cable. In other embodiments, the communication module may also be a wireless communication module or include a wired communication module and a wireless communication module at the same time, where the wireless communication module includes one or more of a WIFI communication module, a ZigBee communication module, and an internet of things card communication module.

In the initial state of the plugging and unplugging device, namely no optical fiber is damaged, when the device normally runs, the three-axis manipulator 5 is also in the initial state, in this state, the Y-axis slider 504 is in the upper limit position, the X-axis slider 508 is in the left limit position, the Z-axis slider 512 is in the rear limit position, and the automatic clamp 513 is in the open state. The coordinate of a certain point on the Z-axis slider 512 or the automatic clamp 513 in this state is taken as a reference coordinate P (X0, Y0, Z0).

In the plugging and unplugging device, it is necessary to number each optical fiber connector 7, measure the coordinates of each optical fiber connector 7 on the front surface of the wiring board 2, and store the number and the coordinate information of each optical fiber connector 7 in the central processing module. In addition, according to the amount of travel of each revolution of the X-axis lead screw 507, the Y-axis lead screw 503 and the Z-axis lead screw 511, the displacement amounts of the X-axis, the Y-axis and the Z-axis when the three-axis manipulator 5 moves to the position of each optical fiber connector 7 are converted into the number of revolutions of the X-axis driving motor 506, the Y-axis driving motor 502 and the Z-axis driving motor 510, and then converted into the control parameters of the control card module for each motor (i.e. each motor is controlled to make several revolutions). In this embodiment, the control card control parameter corresponding to each optical fiber connector 7 is defined as a plugging execution parameter of the optical fiber connector 7.

For example, the coordinate of one optical fiber connector 7 on the front surface of the wiring board 2 is C1(X1, Y1, Z1), when the automatic clamp 513 is moved to the optical fiber connector 7, the travel amounts of the automatic clamp 513 on the X axis, the Y axis, and the Z axis are X1-X0, Y1-Y0, and Z1-Z0, respectively, J for each rotation of the X-axis lead 507, K for each rotation of the Y-axis lead 503, and L for each rotation of the Z-axis lead 511, the corresponding X-axis drive motor 506 needs to rotate (X1-X0)/J turns, Y-axis drive motor 502 needs to rotate (Y1-Y0)/K turns, and Z-axis drive motor 510 needs to rotate (Z1-Z0)/L turns. In this embodiment, the X-axis driving motor 506, the Y-axis driving motor 502, and the Z-axis driving motor 510 all adopt servo motors, which are controlled by pulse signals, and the driving motors rotate one turn when the control card module sends M pulse signals.

Therefore, to move the automatic clamp 513 from the initial position to the optical fiber connector 7 with coordinates C1(X1, Y1, Z1), the control card module needs to send M (X1-X0)/J pulse signals, M (Y1-Y0)/K pulse signals, and M (Z1-Z0)/L pulse signals to the X-axis drive motor 506, the Y-axis drive motor 502, and the Z-axis drive motor 510, respectively. The number of the pulse signals is the corresponding plugging execution parameter of the optical fiber connector 7.

The control box 6 is accessed to the Ethernet, so that the control box is connected with the remote control equipment through a network, the control boxes 6 of a plurality of plugging and unplugging equipment can be connected with the remote control equipment, and the plugging and unplugging equipment can be distinguished through the IP address of the control box 6.

The working principle of the optical fiber plugging and unplugging device is as follows: when detecting that an optical fiber circuit contained in a certain plugging device is in fault, a maintenance person sends a plugging instruction to the plugging device through the remote control device, the plugging instruction contains current damaged optical fiber circuit information, and after the plugging device receives the plugging instruction, the serial number of the optical fiber connector 7 which is being used is determined according to the optical fiber circuit information, and the serial number of the optical fiber connector 7 is automatically allocated. The central processing module reads the plugging and unplugging execution parameters of the currently used optical fiber connector 7 and the plugging and unplugging execution parameters of the selected standby optical fiber connector 7, two groups of plugging and unplugging execution parameters are sent to the control card module through a control instruction, the control card module sends control pulses to each driving motor of the three-axis manipulator 5 according to the previous group of plugging and unplugging control parameters, so that the automatic clamp 513 accurately moves to the currently used optical fiber connector 7, then the control card module outputs a control current signal to the electromagnet 5139, the electromagnet 5139 generates magnetic attraction force by being electrified at the moment, the movable clamping arm 5135 moves downwards to clamp the plug of the jump fiber 13, then the Z-axis driving motor 510 is controlled to rotate reversely, at the moment, the automatic clamp 513 moves backwards along with the plug of the jump fiber 13, and the plug of the jump fiber 13 is unplugged from the front side of the currently used optical. And then, the control card module controls the three-axis manipulator 5 to move according to the next group of plug-pull execution parameters, so that the automatic clamp 513 moves the plug carrying the jump fiber 13 to the selected standby optical fiber connector 7, the automatic clamp 513 is controlled to move forwards, the plug of the jump fiber 13 is inserted into the front side of the standby optical fiber connector 7, the control card module stops outputting control current to the electromagnet 5139, the electromagnet 5139 loses power, the automatic clamp 513 is opened, and the control card module controls the three-axis manipulator 5 to return to the initial position, so that the automatic switching of the optical fiber circuit is completed.

It is worth mentioning that: in this embodiment, the control of the driving motor by the control card module is nonlinear control. Specifically, in the process of executing the plugging operation, when the travel amount of a certain shaft is about to reach the target amount, the control card module reduces the frequency of sending a control pulse signal to the shaft driving motor at a certain advance, so that the travel speed of the shaft is reduced, the travel amount exceeding the target amount due to the excessively high travel speed is avoided, the positioning accuracy of the automatic clamp 513 in each shaft direction is ensured, and the situation of inaccurate positioning is prevented.

As shown in fig. 2, in this embodiment, a plurality of support plates 14 are further disposed on the front surface of the patch panel 2 and between the splicing areas of the cabling grooves 12 and the jump fibers 13, the support plates 14 are arranged at intervals along the height direction of the box body 1, one end of each support plate 14 is connected and fixed with the patch panel 2, the other end of each support plate 14 extends to the front of the patch panel 2, and the end part of the end is tilted upward.

When the jumping fiber 13 is buried in the wiring groove 12, a bending turning part is formed, and the bending turning part is just supported by the supporting plate 14, so that the jumping fiber 13 can be prevented from dropping, and the neatness and the attractiveness of wiring can be kept.

As shown in fig. 5, in the present embodiment, a camera 514 is further mounted on the three-axis robot 5, the camera 514 is connected and fixed to a housing 5131 of the automatic clamp 513, and in other embodiments, the camera 514 may be connected and fixed to the Z-axis slider 512. The camera 514 is provided with a fill light, and the camera 514 is connected with the central processing module. In the process of executing the automatic plugging operation, the camera 514 shoots an operation video picture and sends video data to the central processing module, the central processing module processes the video data and uploads the video data to the remote control device, and maintenance personnel can see the real-time video picture during remote operation, so that the maintenance is facilitated.

In other embodiments, the optical fiber connector 7 may directly adopt an existing optical fiber connector on the market.

Referring to fig. 8, in this embodiment, the optical fiber connector 7 includes a hollow connection sleeve 701, an accommodation cavity 702 for inserting the front end of the optical fiber plug is provided inside the connection sleeve 701, both sides of the connection sleeve 701 are interfaces, a first limiting step 703 is provided at the interface on the front side inside the connection sleeve 701, and the first limiting step 703 is used for abutting against the end surface of the main body of the optical fiber plug, so as to limit the optical fiber plug; a second limiting step 704 is arranged in the connecting sleeve 701 and at the back interface, and the second limiting step 704 is used for abutting against the end face of the main body of the optical fiber plug, so that the optical fiber plug is limited. A first lens 705 and a second lens 706 are arranged in the accommodating cavity 702, the first lens 705 and the second lens 706 are respectively used for butting with the end face of the sleeve 802 of the plug of the jump fiber 13 and the end face of the sleeve 802 of the input fiber 9 (or the output fiber 10), and a space is reserved between the first lens 705 and the second lens 706. The connection sleeve 701 is further provided with a through hole 708, the through hole 708 penetrates through the connection sleeve 701 and is communicated with a space between the first lens 705 and the second lens 706, a light guide member 709 is arranged in the through hole 708, and the light guide member 709 is made of transparent plastic materials or glass materials. Bumps 707 are provided on the inner wall of the connection sleeve 701, and a groove 803 is provided on the main body 801 of the optical fiber plug at a position corresponding to the bumps 707, the groove 803 being used for the bumps 707 to enter. When the fiber optic plug 8 is inserted into the fiber optic connector 7, the nubs 707 enter the grooves 803, thereby locking the fiber optic plug 8.

The working principle of the optical fiber connector 7 is as follows: the plug of the optical fiber skipping is inserted into the front interface of the optical fiber connector 7, the plug of the optical fiber entering (or exiting) is inserted into the back interface of the optical fiber connector 7, when the optical fiber entering (or exiting) normally works, the optical signal is transmitted to the second lens 706 by the optical fiber entering, the light is collimated by the second lens 706 to be changed into parallel light, the parallel light irradiates the first lens 705 again, the parallel light is converged by the first lens 705, and the converged light is transmitted to the optical fiber skipping, so that the transmission of the optical signal is realized. In the process of irradiating light from the second lens 706 to the first lens 705, the space between the first lens 705 and the second lens 706 is illuminated, and a small amount of light is irradiated to the light guide 709, so that the light guide 709 is slightly brightened. Since the inside of the automatic plugging device is relatively dark, the user can see the light guide 709 emitting light outside the optical fiber connector 7.

Maintainer can control the camera and shoot the light pipe on each fiber connector 7 when remote control triaxial manipulator moves, judges whether optical fiber communication line normally works through whether the light pipe shines, can realize long-range patrolling and examining.

In the present embodiment, in order to ensure that the triaxial robot can accurately find the target optical fiber connector 7, an identification label (not shown) is attached to the front surface of the wiring board 2 at a position where each optical fiber connector 7 is located, and information of each identification label is edited in advance and stored in the control box 6. When the control card module controls the three-axis manipulator 5 to move to the target optical fiber connector 7, the central processing module sends an interrupt instruction to the control card, at the moment, the three-axis manipulator 5 does not execute Z-axis action and clamping action, meanwhile, the central processing module controls the camera 514 to shoot the image of the target optical fiber connector 7, processes the image, extracts the identification label area in the image picture, the extracted image picture is subjected to binarization and sharpening processing, so that the character information in the identification label is distinguished, namely the identification information of the optical fiber connector 7, the central processing module compares the identified identification information of the optical fiber connector 7 with the received serial number information of the optical fiber connector 7, therefore, whether the three-axis manipulator 5 accurately reaches the target optical fiber connector 7 or not is judged, the wrong fiber pulling and jumping are avoided, and the condition that the optical fiber is lost is ensured. When the recognition confirms that no error exists, the central processing module sends a control instruction to the control card module, and the control card module controls the three-axis manipulator 5 to execute Z-axis action and clamping action; if the identification is unsuccessful, the control box controls the three-axis manipulator 5 to reset, and the plugging task is executed again after the initialization is completed.
