Moreover, in the current ferrule, when it is inserted and mated with an adapter, an elastic component is arranged on the surface of the ferrule for insertion and clamping. Since the elastic component is arranged on the surface of the ferrule, the outer surface size of the ferrule is too large, which is not conducive to the distribution density, and the manufacturing cost of the ferrule is high.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Referring to Figures 1-8 , a fully automatic optical fiber wiring device includes a wiring box body 1. Mounting plates 2 are fixedly installed on both inner walls of the wiring box body 1. Adapter mounting seats 3 are fixedly installed on one side surface of the two mounting plates 2. A plurality of adapter mounting seats 3 are evenly arranged at equal intervals around the axis of the mounting plate 2. An adapter 4 is fixedly installed on the surface of the adapter mounting seat 3. A plurality of adapters 4 are arranged at equal intervals on the surface of the adapter mounting seat 3.

[0030] An automatic wiring mechanism and an auxiliary wiring mechanism are respectively arranged inside the wiring box body 1. The auxiliary wiring mechanism includes a ferrule 5. A positioning card slot 6 and a plug-in slot 7 are respectively opened on the arc surface of the ferrule 5.

[0031] In order to quickly insert and position the ferrule 5 in the adapter 4 for fixation, a positioning tube 51 is fixedly installed on the inner top wall of the insertion hole of the adapter 4. A plug 52 is threadedly connected to the inner top wall of the positioning tube 51. A first spring 53 is fixedly installed at the bottom of the plug 52. A positioning ball 54 is fixedly installed at the bottom end of the first spring 53. The surface of the positioning ball 54 is slidably inserted into the inner wall of the positioning tube 51. The diameter of the positioning ball 54 is larger than the inner diameter of the bottom end of the positioning tube 51. The arc surface of the positioning ball 54 is slidably inserted into the inner wall of the positioning slot 6. By inserting the ferrule 5 into the adapter 4, the first spring 53 provides elastic force to drive the positioning ball 54 to be clamped inside the positioning slot 6 for positioning and fixation. When pulling out, the pulling force is greater than the extrusion force of the first spring 53, so it can be quickly pulled out. The operation is convenient, and the large structural size of the existing optical fiber connectors is avoided.

[0032] In order to control each optical fiber line 59 to be connected and controlled separately, a plurality of winding wheels 57 and a plurality of torsion springs 58 on the arc surface of each winding rod 56 are equally divided and arranged, and the plurality of winding wheels 57 and the plurality of torsion springs 58 on the surfaces of the plurality of winding rods 56 are cross-distributed. The optical fiber line 59 is wound and connected to the surface of the winding wheel 57. The top end of the optical fiber line 59 is fixedly installed with the bottom end of the ferrule 5. One end of the torsion spring 58 is fixedly installed on the surface of the relative winding wheel 57, and the other end of the torsion spring 58 is fixedly installed on the surface of the winding rod 56. By setting the cross-equal division arrangement, each optical fiber line 59 is wound and connected by the corresponding torsion spring 58 and winding wheel 57 for separate driving, which is convenient for the operation and connection of each optical fiber line 59 and avoids interference.

[0033] In order to automatically wind, collect and store the optical fiber line 59 during non-plugging and unplugging operations, a fiber storage box 55 is fixedly installed on the inner bottom wall of the wiring box body 1. Both inner side walls of the fiber storage box 55 are fixedly installed with winding rods 56. A plurality of winding rods 56 are evenly divided and arranged inside the fiber storage box 55. The arc surface of the winding rod 56 is rotatably connected to the winding wheel 57 through a bearing. The arc surface of the winding rod 56 is movably sleeved with a torsion spring 58. By setting the fiber storage box 55, the optical fiber line 59 is wound and connected by the winding wheel 57, and the torsion spring 58 provides torsion force to wind the optical fiber on the surface of the winding wheel 57 for storage.

[0034] In order to facilitate the grasping operation after arranging and installing a plurality of ferrules 5, a placement seat 510 is fixedly installed on the top of the fiber storage box 55. The surface of the placement seat 510 is in a stepped shape. Connecting holes 511 are formed on the stepped surface of the placement seat 510. The inner walls of each connecting hole 511 are respectively movably sleeved with the corresponding optical fiber lines 59. A plurality of ferrules 5 are respectively located above the relative connecting holes 511. By setting the stepped shape of the placement seat 510, the grasping operation is from high to low during the operation, which avoids interference during the operation and improves the work efficiency.

[0035] By setting up the auxiliary wiring mechanism, it is achieved that components such as the inner shell and the outer shell do not need to be provided on the outer surface of the ferrule 5, greatly reducing the overall size of the fiber optic connector that docks with the adapter 4. Moreover, the positioning ball 54, the first spring 53, and the positioning tube 51 are all arranged inside the adapter 4, and there is no need to set elastic components on the ferrule 5 of the fiber optic connector, further reducing the size of the fiber optic connector. At the same time, the fiber optic connector with a smaller size is matched with the matrix-arranged adapter 4, which can improve the wiring density and reduce the manufacturing cost of the ferrule 5.

[0036] The arc surface of the ferrule 5 is slidably inserted into the insertion hole of the adapter 4. The automatic wiring mechanism includes a manipulator 8. The clamping part of the manipulator 8 is slidably inserted into the insertion groove 7 on the surface of the ferrule 5. The ferrule 5 drives the ferrule 5 to be inserted and pulled out of the adapter 4 through the clamping action of the manipulator 8. The manipulator 8 drives the movement of the ferrule 5 through the automatic wiring mechanism.

[0037] For the front and rear movement adjustment during automatic wiring, at the top and bottom of the inner walls on both sides of the wiring box body 1, slide rails 81 are fixedly installed. The inner walls of the slide rails 81 are slidably inserted with sliders 82. The opposite surfaces of every two sliders 82 are fixedly installed with vertical connecting plates 83. The two vertical connecting plates 83 are arranged oppositely. In the middle of one inner wall of the wiring box body 1, a first bearing seat 84 is fixedly installed. The opposite surfaces of the two first bearing seats 84 are rotatably connected by bearings with a first rotating shaft 85. The arc surface of the first rotating shaft 85 is threadedly connected with the surface of one of the vertical connecting plates 83. On one side surface of one of the first bearing seats 84, a first driving motor 86 is fixedly installed. The output shaft of the first driving motor 86 is fixedly installed with the opposite surface of the first rotating shaft 85 through a coupling. By setting the first driving motor 86 to work, the first rotating shaft 85 rotates forward and backward, thereby controlling the front and rear movement of the vertical connecting plate 83 on the surface of the first rotating shaft 85. By setting the sliding fit of the slide rails 81 and the sliders 82, the smoothness effect of the front and rear movement of the vertical connecting plate 83 is enhanced.

[0038] In order to set up a corresponding overall drive for the structures on both sides of the automatic wiring, the top and bottom of the vertical connecting plate 83 on the left side of the wiring box body 1 are fixedly installed with second bearing seats 87. The top and bottom ends of the vertical connecting plate 83 on the right side of the wiring box body 1 are fixedly installed with limit plates 88. Among them, connecting rods 89 are fixedly installed on the surfaces of the second bearing seats 87 on the top of the wiring box body 1 and the surfaces of the corresponding limit plates 88. The opposite surfaces of the two second bearing seats 87 are rotatably connected through bearings with second rotating shafts 810. Guide rods 811 are fixedly installed on the opposite surfaces of the two limit plates 88. A second driving motor 812 is fixedly installed on the top of one of the second bearing seats 87. The output shaft of the second driving motor 812 is fixedly installed with the opposite end of the second rotating shaft 810 through a coupling. By setting the connecting rod 89, the two vertical connecting plates 83 are connected and fixed, always maintaining a parallel state. By the operation of the second driving motor 812, the second rotation rotates forward and backward to provide the power for the up and down movement. At the same time, the guide rod 811 is set to achieve the guiding drive effect.

[0039] In order to adjust the up and down movement during automatic wiring, a first driving seat 813 is threadedly connected to the arc surface of the second rotating shaft 810. One side surface of the first driving seat 813 is slidably inserted into the opposite surface of the vertical connecting plate 83. A second driving seat 814 is slidably inserted into the arc surface of the guide rod 811. Transverse connecting plates 815 are fixedly installed on the surfaces of the first driving seat 813 and the opposite surface of the second driving seat 814. By setting, the forward and backward rotation of the second rotating shaft 810 controls the up and down movement of the first driving seat 813. The transverse connecting plate 815 is used to control the connection of the first driving seat 813 and the second driving seat 814 into a whole, facilitating the up and down movement of the first driving seat 813 to drive the second driving seat 814 to slide up and down on the surface of the guide rod 811, so as to achieve the effect of smooth up and down movement. At both ends and one side of the transverse connecting plate 815, third bearing seats 816 are fixedly installed. The opposite surfaces of the two third bearing seats 816 are rotatably connected through bearings with third rotating shafts 817. A third driving motor 818 is fixedly installed on one side of one of the third bearing seats 816. The output shaft of the third driving motor 818 is fixedly installed with the opposite surface of the third rotating shaft 817 through a coupling. By setting the forward and backward rotation of the third driving motor 818, the forward and backward rotation of the third rotating shaft 817 is driven, so as to drive the manipulator 8 to move left and right for adjustment.

[0040] In order to drive the manipulator 8 to move smoothly left and right for the forward and reverse operations of the third rotating shaft 817, a third driving seat 819 is threadedly connected to the arc surface of the third rotating shaft 817. One side surface of the third driving seat 819 is slidably inserted into the opposite surface of the transverse connecting plate 815. The bottom of the third driving seat 819 is fixedly installed on the mounting surface of the manipulator 8. By setting the surface of the third driving seat 819 to be slidably inserted into the surface of the transverse connecting rod 89, sliding limit during movement is achieved, facilitating the movement effect of the third driving seat 819.

[0041] By setting up the automatic wiring mechanism, when performing automatic wiring, the first driving motor 86, the second driving motor 812, and the third driving motor 818 are controlled to work through the PLC program. The first driving motor 86 controls the forward and backward movement adjustment of the manipulator 8. The second driving motor 812 controls the up and down movement adjustment of the manipulator 8. The third driving motor 818 controls the left and right movement adjustment of the manipulator 8, driving the manipulator 8 to automatically come to the side of the ferrule 5 that needs wiring. The manipulator 8 is inserted into the insertion slot 7 of the ferrule 5, driving the ferrule 5 to automatically come to the surface of the adapter 4 and be inserted into the adapter 4. The entire process is fully automated. The ferrule 5 is inserted from high to low into the position of the adapter 4 from low to high. The operation is simple and does not interfere with the operator individually, enhancing work efficiency and avoiding the existing manual wiring operation.

[0042] Working principle: During the automatic distribution operation, the forward and reverse operations of the first driving motor 86 are automatically controlled through the PLC program, driving the forward and reverse operations of the first rotating shaft 85. Then, the vertical connecting rod 89 is controlled to move forward and backward, driving the manipulator 8 to come above the ferrule 5. The second driving motor 812 is controlled to work, driving the forward and reverse operations of the second rotating shaft 810. Then, the transverse connecting plate 815 is controlled to move up and down, driving the manipulator 8 to come to the horizontal position of the ferrule 5. The third driving motor 818 is controlled to work, driving the forward and reverse operations of the third rotating shaft 817. Then, the third driving seat 819 is controlled to move, driving the manipulator 8 to come to the side of the ferrule 5. The clamping position of the manipulator 8 is inserted into the insertion slot 7 on the surface of the ferrule 5 to prepare for pulling out the ferrule 5;

[0043] Following the above operations, continue to operate to drive the manipulator 8 to come to the side of the adapter 4, and drive the ferrule 5 to be inserted into the insertion hole of the adapter 4 through the operation of the manipulator 8. The manipulator 8 leaves the inserted ferrule 5 and continues to operate on another ferrule 5.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
