DETAILED DESCRIPTION

[0028] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 10 , an automatic assembly device for an optical cable fiber splitting box, comprising a conveyor belt 1, on which are evenly arranged partitions 11 for separating the fiber splitting boxes, an annular slide rail 2 is arranged above one end of the conveyor belt 1 through a support plate, and two electric sliders 21 are arranged on the annular slide rail 2, and a multi-free angle manipulator 3 is arranged on the left side of the annular slide rail 2 through a U-shaped frame; a bottom template mechanism 4 is arranged at the upper end of the electric slider 21 for placing the fiber splitting plug; a docking limit mechanism 5 is arranged above one of the bottom template mechanisms 4 for fixing the fiber splitting plug; a rotating mechanism 6 is arranged on the rear side of the annular slide rail 2 for rotating the direction of the docking limit mechanism 5, and a pressing component 7 is provided on one side of the rotating mechanism 6.

[0030] During operation, the docking limit mechanism 5 is placed on the rotating mechanism 6 through the multi-free angle manipulator 3 (the multi-free angle manipulator 3 is an existing setting, and its working principle is not repeated here). After the rotating mechanism 6 rotates the docking limit mechanism 5 180 degrees, the pressing component 7 presses the docking limit mechanism 5 to the bottom template mechanism 4. The docking limit mechanism 5 integrally clamps and fixes the multiple fiber splitting plugs placed on the bottom template mechanism 4, and then the bottom template mechanism 4 with the docking limit mechanism 5 is moved to the front side through the electric slider 21. At this time, the docking limit mechanism 5 drives the multiple fiber splitting plugs to dock with the internal docking interface of the fiber splitting box on the conveyor belt 1 through the multi-free angle manipulator 3. Here, it should be noted that the shape of the fiber splitting plug is as follows: Figure 10 As shown, it consists of a wide head part, a narrow head part and a cable head.

[0031] See Figure 1 、 Figure 2 and Figure 10 The bottom template mechanism 4 includes a fixed plate 41 fixedly connected to the electric slider 21, and the four corners of the fixed plate 41 are fixedly connected to the limiting rods 42. The upper end of the fixed plate 41 is fixedly connected to the U-shaped limiting strip 43. A plurality of grooves are evenly opened on the fixed plate 41 and located at the U-shaped limiting strip 43. The grooves are connected to inclined guide bars 44 through springs, and the front and rear sides of the inclined guide bars 44 are inclined to both sides from top to bottom.

[0032] During operation, multiple fiber splitter plugs that need to be plugged in are placed on the fixing plate 41, and the fiber splitter plugs are placed between two adjacent inclined guide bars 44. The multiple inclined guide bars 44 limit the initial positions of the fiber splitter plugs. The two fiber splitter plugs located on the outside are both located in the space formed by the U-shaped limit bar 43. When the docking limit mechanism 5 clamps and fixes multiple fiber splitter plugs at the same time, the fiber splitter plugs on the fixing plate 41 will move from both ends to the middle position. The position change is shown in the attached figure. Figure 10 shown.

[0033] See Figure 1 and Figure 4-Figure 9As shown, the docking limit mechanism 5 includes a docking plate 51, the bottom end of the docking plate 51 is provided with a receiving groove, and two upper and lower clamping plates 52 are slidably arranged in the receiving groove, and the bottom ends of the two groups of clamping plates 52 are provided with evenly distributed clamping plates 53, and the clamping plates 52 at the lower end are provided with a through groove 54 corresponding to the clamping plate 53 at the upper end, and racks 55 are provided on the opposite sides of the two clamping plates 52. A driving gear 56 is rotatably provided inside the receiving groove and between the two clamping plates 52. A driving source is fixedly connected to the rotating shaft of the driving gear 56, and the driving source is located on the inner wall of the receiving groove. The four corners of the bottom end of the docking plate 51 are fixedly connected to the limiting groove 57; the clamping plates 53 at the lower ends of the upper and lower groups of clamping plates 52 are staggered in front and back, and the L-shaped fitting frame 9 is fixedly connected to the side away from the two clamping plates 53 at the front and rear ends.

[0034] During operation, when the docking plate 51 is clamped with the fixing plate 41, the limiting groove 57 is correspondingly inserted into the limiting rod 42 for limiting. The limiting rod 42 is a frustum-shaped structure and plays a guiding role. At the same time, the clamping plates 53 at the lower ends of the upper and lower groups of clamping plates 52 in the accommodating groove are staggered, and the clamping plates 53 on the upper clamping plate 52 and the clamping plates 53 on the lower clamping plate 52 are arranged as a group. Each group of clamping plates 53 is located on both sides of the fiber splitter plug, and the two clamping plates 53 at the front end and the rear end are fixedly connected with an L-shaped The fitting frame 9, the vertical section of the L-shaped fitting frame 9 will fit on the wide head part of the fiber splitter plug, but will not completely contact with the wide head part of the fiber splitter plug, so as not to affect the subsequent docking of the fiber splitter plug with the internal docking interface of the fiber splitter box. The driving source on the rotating shaft of the active gear 56 is started to drive the active gear 56 to rotate. The active gear 56 engages the racks 55 on the upper and lower clamping plates 52 to move, thereby driving the upper and lower clamping plates 52 to move toward each other, so that the fiber splitter plugs with some spacing are close to each other until the wide head parts of all the fiber splitter plugs are completely fitted.

[0035] See Figure 1 and Figure 3 The rotating mechanism 6 includes a half gear 61 connected by a cylindrical rod, and a rotating gear 62 is meshed with the half gear 61. The lower end of the rotating gear 62 is rotatably connected to a rotating ring 63, and the bottom end of the rotating ring 63 is fixedly connected to a bracket 64. A placement slot 65 is provided in the middle of the rotating gear 62, and a symmetrical clearance slot is provided on the inner wall of the placement slot 65. An inclined block bar 66 is connected to the clearance slot through a connecting spring.

[0036] During operation, the docking plate 51 is moved into the placement slot 65 by the multi-free angle manipulator 3, and the docking of the docking plate 51 and the multi-free angle manipulator 3 is released. It should be noted here that the area of ​​the placement slot 65 is slightly larger than the area of ​​the docking plate 51, but the inclined baffle 66 in the placement slot 65 will support the bottom end of the placed docking plate 51 in a natural state, and the placement slot 65 is located directly above the bottom template mechanism 4 on the rear side. Since the fiber splitter plug clamped on the docking plate 51 is docked with the internal interface of the fiber splitter box at the upper end of the conveyor belt 1, the U-shaped opening of the U-shaped limit strip 43 at the bottom end of the docking plate 51 is set to the left, and when it is to be clamped with the fiber splitter plug located on the upper side of the rear fixed plate 41, the docking plate 51 needs to be rotated 180 degrees. When the half gear 61 rotates one circle, it will drive the rotating gear 62 to rotate 180 degrees, thereby driving the docking plate 51 to rotate 180 degrees.

[0037] See Figure 1 and Figure 3 The pressing assembly 7 includes a mating gear 71 meshingly connected to the right side of the rotating gear 62. The lower end of the mating gear 71 is rotatably connected to the fixing ring 72. The bottom end of the fixing ring 72 is fixedly connected to a fixing rod 73. The upper end of the mating gear 71 is fixedly connected to an L-shaped frame 74. The other end of the L-shaped frame 74 is fixedly connected to an electric telescopic rod 75. The bottom end of the electric telescopic rod 75 is fixedly connected to a rectangular plate. A plurality of spring telescopic rods 76 are distributed in a matrix at the bottom end of the rectangular plate. The bottom end of the spring telescopic rod 76 is fixedly connected to a pressing plate 77.

[0038] During operation, when the docking plate 51 placed on the rotating gear 62 rotates 180 degrees, the rotating gear 62 will synchronously engage with the matching gear 71 to rotate, and the matching gear 71 drives the upper L-shaped frame 74 to rotate to just above the docking plate 51, and starts the electric telescopic rod 75 to drive the rectangular plate to move downward until the pressure plate 77 presses the docking plate 51 downward. The docking plate 51 is located just above the fixed plate 41. Since the spring telescopic rod 76 is flexible, it is convenient to dock the docking plate 51 with the fixed plate 41.

[0039] See Figure 2 、 Figure 4 and Figure 5The multi-angle manipulator 3 has a connection block 31 fixedly connected to the lower side of one end. Positioning slots 32 are provided on the front and rear sides of the connection block 31. A connection slot 58 corresponding to the connection block 31 is provided on the upper end of the docking plate 51. U-shaped slots 59 are provided on the upper end of the docking plate 51 and on both sides of the connection slot 58. An alignment component 50 for clamping the connection block 31 is provided in the U-shaped slot 59. The alignment component 50 includes a bidirectional threaded rod 501 rotatably connected to the inside of the U-shaped slot 59. A driving source is provided at one end of the bidirectional threaded rod 501. Threaded sleeves 502 are threadedly connected to both sides of the bidirectional threaded rod 501. An inverted L-shaped rod 503 is fixedly connected to the upper end of the threaded sleeve 502, and the inverted L-shaped rod 503 is slidably connected to the U-shaped slot 59.

[0040] During operation, when the electric slider 21 drives the bottom template mechanism 4 and the docking limit mechanism 5 located on the rear side to move to the front end of the conveyor belt 1, the multi-freedom angle manipulator 3 is moved to just above the docking limit mechanism 5 located on the front side, and the connecting block 31 is correspondingly inserted into the connecting groove 58, the driving source of the bidirectional threaded rod 501 is started, which can be a motor, to drive the bidirectional threaded rod 501 to rotate, and then drive the two threaded sleeves 502 to move toward each other on the bidirectional threaded rod 501, until the threaded sleeves 502 drive the inverted L-shaped rod 503 to be respectively inserted into the positioning groove 32 on the connecting block 31, thereby realizing the docking of the multi-freedom angle manipulator 3 and the docking limit mechanism 5.

[0041] See Figure 4 and Figure 6 The bottom end of the docking plate 51 also includes a limit plate 8 corresponding to the docking interface inside the fiber distribution box. The upper end of the limit plate 8 is connected to the bottom end of the placement groove 82 opened on the docking plate 51 through a compression spring 81. A connecting rod 83 is rotatably connected in the placement groove 82. A cam 84 is fixedly connected to the upper side of the corresponding limit plate 8 on the connecting rod 83, and a driving source is provided at one end of the connecting rod 83.

[0042] During operation, when the multi-free angle manipulator 3 drives the docking limit mechanism 5 to move above the conveyor belt 1, the multi-free angle manipulator 3 first drives the docking limit mechanism 5 to move upward, and then moves to above the conveyor belt 1. The docking limit mechanism 5 simultaneously drives multiple fiber distribution plugs to move into the fiber distribution box on the conveyor belt 1. During movement, the docking plate 51 is no longer limited by the fixed plate 41, and multiple fiber distribution plugs will be separated from the upper end of the fixed plate 41. When the lower end of the docking plate 51 enters the interior of the fiber distribution box, the front and rear limit grooves 57 just fit together with the front and rear inner walls of the fiber distribution box, and at the same time, the driving source on the connecting rod 83 is started to drive the connecting rod 83 to rotate. The connecting rod 83 will drive the cam 84 to rotate. When the raised part of the cam 84 rotates to the top of the limit plate 8, it will squeeze the limit plate 8 to move downward. In the natural state of the compression spring 81, the bottom end of the limit plate 8 is higher than the bottom end of the limit slot 57. Under the extrusion of the cam 84, the bottom end of the limit plate 8 will be lower than the bottom end of the limit slot 57, and the limit plate 8 will be on both sides of the docking interface inside the fiber splitting box. When the multi-free angle manipulator 3 drives the docking limit mechanism 5 to move toward the inner side of the docking interface inside the fiber splitting box, the limit plate 8 will move on both sides of the docking interface inside the fiber splitting box, playing the role of limiting guidance until multiple fiber splitting plugs are plugged into the docking interface inside the fiber splitting box together, and the clamping plate 53 is released to limit the fiber splitting plugs. The conveyor belt 1 drives the already plugged fiber splitting box to move to the next process, and the subsequent fiber splitting box to be plugged continues to move, and the multi-free angle manipulator 3 drives the docking plate 51 to move to the rotating mechanism 6, and then continues to the next cycle operation.
