Description

Technical Field

[0001] This utility model belongs to the field of fiber optic patch cord cutting technology, specifically relating to an easy-to-position fiber optic patch cord cutting device. Background Technology

[0002] Fiber optic patch cords are key components used to connect optical communication equipment (such as optical transceivers, switches, and routers) to fiber optic cabling links. They are equipped with connector plugs at both ends to enable flexible connection of optical paths. They mainly include LC type, SC type, FC type, ST type and MPO type.

[0003] When using fiber optic patch cords, they need to be cut. The usual procedure is to first strip the fiber optic patch cord, then fix the patch cord in place, push the blade to cut a notch on the exposed fiber, and then use the anvil on the cover of the fiber optic cleaver to break the bare fiber into two pieces from the small opening. The fiber ends cut in this way are flat and easy to splice.

Detailed Implementation

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] Please see Figures 1-6 The present invention provides the following technical solution: an easy-to-position fiber optic patch cord cutting device, including a cutting platform 1, and further including: a moving horizontal plate 2, an electric drive mechanism 3, a clamping mechanism 4, a positioning mechanism 5, an adjustment mechanism 6, a support base 7, and a cutting mechanism 8.

[0058] Furthermore, by Figure 1 and Figure 4 As shown, in this embodiment, the movable horizontal plate 2 is slidably disposed on the top of the cutting platform 1. The electric drive mechanism 3 is used to drive the movable horizontal plate 2 to move. The clamping mechanism 4 is fixed to the top surface of the movable horizontal plate 2 and is used to clamp the end of the optical fiber jumper. The positioning mechanism 5 includes a fixed frame 51 slidably disposed on the side of the cutting platform 1, a slotted photoelectric sensor 52 fixed to the top of the fixed frame 51, and a sensing plate 53 fixed to the side of the movable horizontal plate 2, wherein the sensing plate 53 corresponds to the slot of the slotted photoelectric sensor 52. The adjustment mechanism 6 is used to adjust the horizontal position of the positioning mechanism 5. The support base 7 is fixed to the top surface of the cutting platform 1, and a cutting groove 71 is opened in the support base 7. A lead wire hole 72 is opened at the top of the support base 7. The cutting mechanism 8 cooperates with the support base 7 to cut the optical fiber jumper. With the above scheme, when in use, the optical fiber is fed by the feeding roller, which is driven by a motor and rotates smoothly to feed the fiber.

[0059] During processing, the horizontal position of the fixed frame 51 in the positioning mechanism 5 is adjusted by the adjustment mechanism 6 according to the required length of the fiber optic jumper, thereby changing the position of the slotted photoelectric sensor 52 on the side of the cutting platform 1 to determine the moving distance of the moving horizontal plate 2 and realize the preset cutting length.

[0060] The optical fiber is fed by a feeding roller, so that the end of the optical fiber passes through and extends out of the lead hole 72;

[0061] Subsequently, the electric drive mechanism 3 is activated, which drives the moving horizontal plate 2 to slide on the top of the cutting platform 1, thereby moving the clamping mechanism 4 closer to the optical fiber until the clamping mechanism 4 moves to the position of the optical fiber and clamps the end of the optical fiber.

[0062] Subsequently, the electric drive mechanism 3 drives the moving horizontal plate 2 back to the initial position, and the clamping mechanism 4 pulls the optical fiber to move together.

[0063] During the movement of the moving horizontal plate 2, the sensing plate 53 fixed to its side also moves. When the sensing plate 53 moves to the slot position of the corresponding slot-shaped photoelectric sensor 52, the sensing plate 53 blocks the light path of the slot-shaped photoelectric sensor 52. The slot-shaped photoelectric sensor 52 detects the signal change and transmits the signal to the control system. After receiving the signal, the control system controls the electric drive mechanism 3 to stop driving, so that the moving horizontal plate 2 is accurately positioned. At this time, the position of the fiber optic jumper to be cut corresponds to the lead hole 72 and the cutting slot 71 at the top of the support base 7.

[0064] Finally, the cutting mechanism 8 operates in conjunction with the support base 7 to cut the fiber optic patch cord located at the cutting slot 71.

[0065] After cutting, release the clamping mechanism 4, take out the cut fiber optic patch cord, and complete one cutting operation.

[0066] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the electric drive mechanism 3 includes: a first moving stage 31, two first fixed plates 32, a first threaded screw 33, and a drive motor 34. The first moving stage 31 is fixed to the bottom surface of the moving horizontal plate 2, the two first fixed plates 32 are symmetrically fixed to the top surface of the cutting platform 1, the first threaded screw 33 is rotatably installed between the two first fixed plates 32 and connected to the first moving stage 31 by threaded engagement, and the drive motor 34 is fixed to the first fixed plate 32 to drive the first threaded screw 33 to rotate. With the above scheme, when in use, after the end of the optical fiber passes through and extends out of the lead hole 72, the drive motor 34 is energized and started. The output shaft of the drive motor 34 is fixedly connected to the first threaded screw 33 by a coupling. Therefore, after the drive motor 34 is energized and started, it outputs torque and drives the first threaded screw 33 to rotate.

[0067] Since the first threaded screw 33 is connected to the first moving platform 31 by thread engagement, the first threaded screw 33 drives the first moving platform 31 to move horizontally after it rotates.

[0068] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the electric drive mechanism 3 further includes two guide rails 35 and two sliders 36. The two guide rails 35 are symmetrically fixed to the top surface of the cutting platform 1, and the two sliders 36 are symmetrically fixed to the bottom surface of the moving horizontal plate 2 and slide in cooperation with the guide rails 35. With the above scheme, when the electric drive mechanism 3 drives the first moving stage 31 to move horizontally, since the two sliders 36 are symmetrically fixed to the bottom surface of the moving horizontal plate 2 and slide in cooperation with the guide rails 35, the first moving stage 31 can drive the sliders 36 to move along the guide rails 35.

[0069] Two guide rails 35 and two sliders 36 work together to support and guide the first moving stage 31, further improving the stability of the first moving stage 31.

[0070] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the clamping mechanism 4 includes: a cylinder seat 41, a movable vertical plate 42, a pneumatic gripper 43, and a horizontal cylinder 44. The cylinder seat 41 is fixed to the top surface of the movable horizontal plate 2, the movable vertical plate 42 is located in front of the cylinder seat 41, the pneumatic gripper 43 is fixed to the movable vertical plate 42 and is used to clamp the end of the optical fiber patch cord, and the horizontal cylinder 44 is fixed to the cylinder seat 41. Its piston rod passes through the cylinder seat 41 and is fixedly connected to the movable vertical plate 42. With the above scheme, when the pneumatic gripper 43 moves to the position of the optical fiber end, the pneumatic gripper 43 is activated and the two grippers of the pneumatic gripper 43 clamp the end of the optical fiber.

[0071] If the pneumatic gripper 43 still cannot directly grip the optical fiber when the first moving stage 31 moves to its maximum position, the horizontal cylinder 44 is activated, causing the piston rod of the horizontal cylinder 44 to extend. The piston rod pushes the moving vertical plate 42 to move, allowing the pneumatic gripper 43 to get closer to the optical fiber.

[0072] After the pneumatic gripper 43 clamps the optical fiber, the horizontal cylinder 44 is activated again, and the piston rod of the horizontal cylinder 44 pulls the moving vertical plate 42 back to the initial position.

[0073] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the clamping mechanism 4 further includes two guide rods 45, which are symmetrically fixed to the outer wall of the movable vertical plate 42 and pass through the cylinder seat 41. With the above solution, the two guide rods 45 are used to guide the movable vertical plate 42 during use, which further improves the stability of the movable vertical plate 42.

[0074] Preferably, by Figure 1 and Figure 4 As shown in this embodiment, the positioning mechanism 5 further includes a scale 54, which is fixed to the side of the cutting platform 1 and passes through the fixing frame 51. An identification hole 511 is provided on the outer wall of the fixing frame 51. With the above solution, during use, when adjusting the horizontal position of the slotted photoelectric sensor 52 by the adjustment mechanism 6, the identification hole 511 will pass through different scale lines on the scale 54. The corresponding scale value can be clearly seen through the identification hole 511, ensuring the accuracy of cutting and achieving precise positioning.

[0075] Optionally, by Figure 1 and Figure 5 As shown, in this embodiment, the adjustment mechanism 6 includes: a second moving stage 61, two second fixing plates 62, a second threaded rod 63, and a handwheel 64. The second moving stage 61 is fixed to the bottom surface of the fixing frame 51. The two second fixing plates 62 are symmetrically fixed to the side of the cutting platform 1. The second threaded rod 63 is rotatably installed between the two second fixing plates 62 and connected to the second moving stage 61 by a threaded engagement. The handwheel 64 is fixed to one end of the second threaded rod 63. With the above scheme, when it is necessary to adjust the horizontal position of the slotted photoelectric sensor 52, the second threaded rod 63 is rotated by the handwheel 64. Since the second threaded rod 63 is connected to the second moving stage 61 by a threaded engagement, the second threaded rod 63 will drive the second moving stage 61 to move when it rotates. The second moving stage 61 drives the slotted photoelectric sensor 52 to move horizontally through the fixing frame 51.

[0076] Optionally, by Figure 1 and Figure 6 As shown in this embodiment, the cutting mechanism 8 includes: two side plates 81, a top plate 82, a blade 83, and a vertical cylinder 84. The two side plates 81 are symmetrically fixed to the top surface of the cutting platform 1, the top plate 82 is fixed to the top of the side plates 81, the blade 83 is located below the top plate 82 and faces the cutting groove 71, and the vertical cylinder 84 is fixed to the top surface of the top plate 82. Its piston rod passes through the top plate 82 and is fixedly connected to the blade 83. With the above scheme, when the optical fiber is positioned, the vertical cylinder 84 is started, and the piston rod of the vertical cylinder 84 drives the blade 83 to move down, so that the blade 83 gradually enters the cutting groove 71 to cut the optical fiber.

[0077] Preferably, by Figure 1 and Figure 6As shown in this embodiment, the cutting mechanism 8 further includes two guide columns 85, which are symmetrically fixed to the top surface of the blade 83 and penetrate the top plate 82. With the above solution, the two guide columns 85 are used to guide the blade 83 during use, thereby improving the stability of the blade 83.

[0078] It should be noted that the drive motor 34, pneumatic gripper 43, horizontal cylinder 44, slotted photoelectric sensor 52, and vertical cylinder 84 are all commercially available conventional equipment. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0079] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0080] Components not described in detail in this article are existing technologies.

[0081] The working principle and usage process of this utility model: In the cutting equipment of this utility model, the optical fiber is fed by the feeding roller, which is driven by a motor and rotates smoothly to feed the fiber.

[0082] During processing, based on the required length of the fiber optic patch cord to be cut, the horizontal position of the fixed frame 51 in the positioning mechanism 5 is adjusted using the adjustment mechanism 6, thereby changing the position of the slotted photoelectric sensor 52 on the side of the cutting platform 1 to determine the moving distance of the moving horizontal plate 2, thus achieving the preset cutting length.

[0083] The optical fiber is fed by a feeding roller, so that the end of the optical fiber passes through and extends out of the lead hole 72;

[0084] Subsequently, the electric drive mechanism 3 is activated, which drives the moving horizontal plate 2 to slide on the top of the cutting platform 1, thereby moving the clamping mechanism 4 to move closer to the optical fiber until the clamping mechanism 4 moves to the position of the optical fiber and clamps the end of the optical fiber.

[0085] Subsequently, the electric drive mechanism 3 drives the moving horizontal plate 2 back to the initial position, and the clamping mechanism 4 pulls the optical fiber to move together;

[0086] During the movement of the moving horizontal plate 2, the sensing plate 53 fixed to its side also moves. When the sensing plate 53 moves to the slot position of the corresponding slot-shaped photoelectric sensor 52, the sensing plate 53 blocks the light path of the slot-shaped photoelectric sensor 52. The slot-shaped photoelectric sensor 52 detects the signal change and transmits the signal to the control system. After receiving the signal, the control system controls the electric drive mechanism 3 to stop driving, so that the moving horizontal plate 2 is accurately positioned. At this time, the position of the fiber optic jumper to be cut corresponds to the lead hole 72 and the cutting slot 71 at the top of the support base 7.

[0087] Finally, the cutting mechanism 8 operates in conjunction with the support base 7 to cut the fiber optic patch cord located at the cutting slot 71.

[0088] After the cutting is completed, release the clamping mechanism 4, take out the cut fiber optic patch cord, and complete one cutting operation;

[0089] This utility model uses an electric drive mechanism 3 to move a moving horizontal plate 2, a positioning mechanism 5 to achieve automatic positioning by using a slotted photoelectric sensor 52 and a sensing plate 53, an adjustment mechanism 6 to manually adjust the horizontal position of the positioning mechanism 5, a clamping mechanism 4 to fix the fiber optic jumper, and a cutting mechanism 8 to complete the cutting by working with a support base 7. This solves the problem of low efficiency of manual positioning in the prior art and has the characteristics of high automation and accurate positioning.

[0090] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
