Description

Technical Field

[0001] The present invention relates to the technical field of optical cable preparation, in particular to an automatic fiber shearing device. Background Art

[0002] In the optical cable preparation process, optical fiber sheathing is one of the important processing technologies. Optical fiber sheathing is to prepare a loose tube or bundle tube outside the optical fiber to protect the optical fiber. When sheathing the optical fiber, the optical fiber in the optical fiber reel needs to be introduced into the sheathing machine through the fiber laying equipment. The sheathing machine extrude the sheathing plastic outside the optical fiber to form a loose tube or bundle tube. According to the requirements of the production order, the length of the optical fiber sheathing generally varies from 2km to 24km, but the optical fiber is generally 24km or 48km in the optical fiber reel. Therefore, one reel of optical fiber can complete the sheathing process of multiple lengths. After completing a sheathing process, the optical fiber needs to be cut.

[0003] The existing fiber cutting device directly cuts the optical fiber. Since the fiber-releasing equipment provides a certain pay-out tension during the fiber-releasing process, after the optical fiber is suddenly cut, the optical fiber that is stretched under the tension will jump wires, and the jump wires will be entangled in the pay-out equipment, affecting the continued use of the pay-out equipment. At the same time, when the fiber-releasing equipment suddenly cuts the optical fiber during the high-speed pay-out process, the fiber-releasing equipment cannot be shut down immediately and requires a buffered shutdown process. During this process, the optical fiber will continue to be paid out. After the paid-out optical fiber is scattered, it cannot be wound into the optical fiber reel again. The tail end optical fiber needs to be cut when it is used next time, resulting in waste of optical fiber. Summary of the Invention

[0004] To this end, the technical problem to be solved by the present invention is to overcome the problem in the prior art that after the optical fiber is cut, the pay-out equipment cannot be shut down immediately, resulting in optical fiber waste. An automatic fiber cutting device is provided, which can clamp the optical fiber end immediately when cutting the optical fiber to prevent the optical fiber from jumping or rebounding, and can drive the optical fiber to rotate, wind and recycle the excess optical fiber, and avoid optical fiber waste.

At the same time, the first pressing block and the second pressing block clamp the head end of the cut optical fiber.

[0008] The fiber winding power source is connected to the fiber shearing table. After the fiber shearing table completes the fiber shearing action, the fiber winding power source drives the fiber shearing table to rotate forward, and the first pressure block and the second pressure block clamp the cut optical fiber and wind it around the outer periphery of the fiber shearing table. After the fiber release device stops, the fiber winding power source drives the fiber shearing table to rotate in the opposite direction to return the optical fiber to the fiber release device.

[0009] In one embodiment of the present invention, a first arc surface is provided on a side of the first shearing block away from the fiber passage, and a second arc surface is provided on a side of the second shearing block away from the fiber passage. The first arc surface and the second arc surface are on both sides of the fiber passage, and a line connecting the first arc surface and the second arc surface extending in the direction of the fiber passage forms a circumferential surface.

[0010] In one embodiment of the present invention, baffles higher than the first arc surface and the second arc surface are provided on both sides of the first arc surface and the second arc surface.

[0011] In one embodiment of the present invention, arc chamfers are provided on ends of the first arc surface and the second arc surface close to the fiber passage.

[0017] A gas-electric slip ring is provided at the end of the rotating shaft, wherein the rotary joint of the gas-electric slip ring is connected to the rotating shaft, the rotary joint of the gas-electric slip ring is connected to the cylinder of the fiber cutting power source through an air pipe, and the fixed joint of the gas-electric slip ring is connected to the air supply device through an air pipe;

[0018] The servo motor is connected to the rotating shaft through a transmission assembly, and the servo motor drives the rotating shaft to rotate.

[0019] In one embodiment of the present invention, the device further comprises: a photoelectric detection sensor, the photoelectric detection sensor being used to define an initial position and a rotation position of the fiber shearing table;

[0020] When the photoelectric detection sensor defines the initial position of the fiber shearing table, the fiber passage is set as a horizontal passage;

[0021] When the photoelectric detection sensor limits the rotation position of the fiber shearing table, the fiber shearing table is configured to stop after reaching a preset rotation angle.

[0023] In one embodiment of the present invention, it also includes a shell, which is covered outside the fiber cutting table. The shell includes a base and a cover that can be opened and closed.

[0026] The automatic fiber shearing device of the present invention is provided with a fiber shearing table including a first fiber shearing block and a second fiber shearing block. A pressing block and a fiber knife are provided at positions corresponding to the first fiber shearing block and the second fiber shearing block. The pressing block and the fiber knife are configured to move synchronously. While the fiber knife shears the optical fiber, the pressing block can clamp and fix the head end of the cut optical fiber, thereby preventing the optical fiber jumper from being stretched under tension and preventing the optical fiber from flying and entangled on the fiber laying equipment.

[0027] Moreover, after the fiber shearing is completed, since the fiber-releasing device cannot stop rotating immediately, excess optical fiber will continue to be released. The automatic fiber shearing device of the present invention is provided with a fiber winding power source to drive the fiber shearing table to rotate forward after the fiber shearing table completes the fiber shearing action. Since the head end of the optical fiber is clamped and fixed, during the rotation of the fiber shearing table, excess optical fiber can be wound around the outer periphery of the fiber shearing table.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0038] In the field of optical cable preparation, fiber cutting devices are generally used in conjunction with fiber-releasing equipment. In practice, the inventors of the present application found that after the optical fiber is cut by the automatic fiber cutting device of the prior art, the optical fiber is suddenly cut because the fiber-releasing equipment provides a certain pay-out tension when paying out the cable. The optical fiber stretched under the tension will jump wires, and the jump wires will be entangled in the pay-out equipment, affecting the continued use of the pay-out equipment. At the same time, when the fiber-releasing equipment is in the high-speed pay-out process, when the optical fiber is cut, the fiber-releasing equipment cannot be shut down immediately and requires a buffered shutdown process. During this process, the optical fiber will continue to be paid out. After the released optical fiber is scattered, it cannot be wound into the optical fiber reel again. The tail end optical fiber needs to be cut when it is used next time, resulting in waste of optical fiber.

[0039] In order to solve the above problems, the present invention provides an automatic fiber cutting device, which can clamp the fiber end immediately when cutting the optical fiber to prevent the fiber from jumping or rebounding, and can drive the optical fiber to rotate, wind and recycle the excess optical fiber to avoid waste of optical fiber.

[0040] The cylindrical battery of the present invention is further explained below with reference to specific embodiments.

[0041] Reference Figure 1 As shown, the present invention discloses an automatic fiber cutting device, which is used in conjunction with a fiber-releasing device and is arranged at the rear end of the fiber-releasing device, comprising a fiber cutting platform 1 and a fiber winding power source 2, wherein: after the optical fiber is released from the fiber-releasing device, it passes through the fiber cutting platform 1. During the normal pay-off process, the fiber cutting platform 1 does not affect the pay-off of the optical fiber. When the optical fiber needs to be cut, the fiber cutting platform 1 cuts the optical fiber and can clamp the optical fiber head end near one end of the fiber-releasing device. At this time, the fiber-releasing device receives a stop command, but the pay-off device is a high-speed rotating pay-off, and the pay-off process needs to be slowly stopped. Therefore, there is still excess optical fiber from the pay-off device. In preparation for release, the fiber winding power source 2 is connected to the fiber cutting table 1. After the fiber cutting table 1 completes the fiber cutting action, the fiber winding power source 2 drives the fiber cutting table 1 to rotate forward. Since the head end of the optical fiber is clamped and fixed, during the rotation of the fiber cutting table 1, the excess optical fiber can be wound around the outer periphery of the fiber cutting table 1. After the fiber releasing equipment is completely shut down, the fiber winding power source 2 will also stop rotating to prevent the optical fiber from being broken. Finally, the fiber winding power source 2 is controlled to drive the fiber cutting table 1 to rotate in the opposite direction, and the fiber releasing equipment also reverses at the same time, so that the optical fiber wound outside the fiber cutting table 1 can be returned to the fiber releasing equipment, thereby avoiding waste of optical fiber.

[0042] Specifically, refer to Figure 2As shown, the fiber cutting table 1 of the present invention includes a first fiber cutting block 11, a second fiber cutting block 12 and a fiber cutting power source 13, and the fiber cutting power source 13 drives the first fiber cutting block 11 and the second fiber cutting block 12 to move toward or in the opposite direction. When the fiber cutting power source drives the first fiber cutting block 11 and the second fiber cutting block 12 to move in the opposite direction, a fiber passing channel 14 is provided between the first fiber cutting block 11 and the second fiber cutting block 12, and the optical fiber is introduced into the fiber passing channel 14 and passes through the fiber passing channel 14. During the normal pay-off process, it is ensured that the optical fiber does not contact the first fiber cutting block 11 and the second fiber cutting block 12. When the fiber cutting power source 13 drives the first fiber cutting block 11 and the second fiber cutting block 12 to move toward each other, the first fiber cutting block 11 and the second fiber cutting block 12 cooperate to cut the optical fiber.

[0043] Reference Figure 4 and Figure 5 As shown, a first pressing block 111 and a first fiber shearing knife 112 are provided on the side of the first fiber shearing block 11 facing the fiber passage 14, and a second pressing block 121 and a second fiber shearing knife 122 are provided on the side of the second fiber shearing block 12 facing the fiber passage 14. The first pressing block 111 and the second pressing block 121 are arranged in corresponding positions, and the first fiber shearing knife 112 and the second fiber shearing knife 122 are arranged in corresponding positions. The first fiber shearing knife 112 and the second fiber shearing knife 122 cooperate to complete the fiber shearing action. At the same time, the first pressing block 111 and the second pressing block 121 clamp the head end of the cut optical fiber, which can prevent the optical fiber from being stretched under tension from jumping wires and prevent the optical fiber from flying and winding around the fiber release equipment.

[0044] It should be noted that, due to the characteristics of optical fiber, optical fiber has greater tensile strength when bent, but optical fiber is easily broken after being bent. Therefore, when the fiber cutting table 1 of the present invention is set to wind the optical fiber, it is necessary to prevent the optical fiber from being bent. In order to achieve this effect, in this embodiment, a first arc surface 113 is provided on the side of the first cutting block 11 away from the fiber passage 14, and a second arc surface 123 is provided on the side of the second cutting block 12 away from the fiber passage 14. The first arc surface 113 and the second arc surface 123 are on both sides of the fiber passage 14, and the first arc surface 113 and the second arc surface 123 extend in the direction of the fiber passage 14 to form a circumferential surface. When the fiber cutting table 1 winds the optical fiber, it can ensure that the optical fiber is wound on the circumferential surface, and the bending angle of the optical fiber can be minimized to prevent the optical fiber from being broken.

[0045] Moreover, in this embodiment, the optical fiber is clamped in the fiber passage 14, and the clamped optical fiber needs to be led out from the fiber passage 14. Arc chamfers 15 are provided at the ends of the first arc surface 113 and the second arc surface 123 close to the fiber passage 14, so that the bending angle of the optical fiber can be minimized to prevent the optical fiber from being broken.

[0046] In this embodiment, baffles 16 higher than the first arc surface 113 and the second arc surface 123 are provided on both sides of the first arc surface 113 and the second arc surface 123. The two baffles 16 can limit the lateral movement of the optical fiber and prevent the optical fiber from slipping out from both sides of the fiber cutting table 1.

[0047] In this embodiment, the fiber cutting power source 13 is set to drive the first fiber cutting block 11 and the second fiber cutting block 12 to move toward or in the opposite direction. Figure 3 As shown, the fiber cutting power source 13 includes: a cylinder 131 and a guide assembly 132, wherein: the cylinder 131 includes a cylinder body and a piston rod driven by the cylinder body, the cylinder body of the cylinder 131 is fixed on the first fiber cutting block 11, and the piston rod of the cylinder 131 is connected to the second fiber cutting block 12. In other embodiments, the cylinder body of the cylinder 131 can also be fixed on the second fiber cutting block 12, and the piston rod of the cylinder 131 can be connected to the first fiber cutting block 11. Other driving modes can also be set; the guide The component 132 includes a fixing seat fixed on the first shearing block 11, a guide rod arranged on the fixing seat, and a bearing seat fixed on the second shearing block 12, wherein the guide rod extends toward the direction of the second shearing block 12 and is passed through the bearing seat. The guide component 132 can accurately limit the relative movement direction of the first shearing block 11 and the second shearing block 12, so that the first shearing knife 112 and the second shearing knife 122 can accurately cooperate to cut the optical fiber, ensuring that the cut surface of the optical fiber is flat and does not affect the subsequent use of the optical fiber.

[0048] In this embodiment, referring to Figure 6 As shown, the fiber winding power source 2 includes: a servo motor 21, a transmission assembly 22 and a rotating shaft 23. The servo motor 21 is connected to the rotating shaft 23 through the transmission assembly 22. The servo motor 21 drives the rotating shaft 23 to rotate. The rotating shaft 23 can be inserted into the fiber shearing table 1. When the rotating shaft 23 rotates, it can drive the fiber shearing table 1 to rotate.

[0049] It should be noted that, in this embodiment, the fiber cutting power source 13 is a cylinder 131, so an air pipe needs to be connected to supply air for it. Since the fiber cutting power source 13 is arranged on the fiber cutting table 1, it needs to rotate synchronously with the fiber cutting table 1. When rotating, the air pipe is easily entangled on the fiber cutting table 1, causing the fiber cutting table 1 to be unable to rotate. In order to solve this problem, the fiber winding power source 2 also includes an air-electric slip ring 24, which is arranged at the end of the rotating shaft 23. The rotary joint of the air-electric slip ring 24 is connected to the rotating shaft 23, and the rotary joint can rotate synchronously with the rotating shaft 23. The rotary joint of the air-electric slip ring 24 is connected to the cylinder 131 of the fiber cutting power source 13 through the air pipe. In this way, the rotary joint and the fiber cutting power source 13 rotate synchronously, and the air pipe is always in a relatively parallel position, and the air pipe will not be entangled or knotted. The fixed joint of the air-electric slip ring 24 is connected to the air supply equipment through the air pipe, and the fixed joint is not affected by the rotation of the fiber cutting table 1.

[0050] In this embodiment, the optical fiber passes through the fiber passage 14. During the normal pay-off process, it is necessary to ensure that the optical fiber does not contact the first shearing block 11 and the second shearing block 12. At the same time, after the fiber pay-off device is completely shut down, the fiber power source 2 also needs to stop rotating. This requires limiting the initial position and rotation angle of the entire shearing table 1. Figure 1 As shown, in this embodiment, when a first photoelectric detection sensor 3 is set to limit the initial position of the fiber cutting table 1, a corresponding detected component is set in the fiber cutting table 1. When the first photoelectric detection sensor 3 detects the detected component, it indicates that the fiber cutting table 1 is already in a horizontal position, and the fiber passing channel 14 provided in the fiber cutting table 1 is a horizontal channel; similarly, when a second photoelectric detection sensor 4 is set to limit the rotation position of the fiber cutting table 1, when the first photoelectric detection sensor 3 detects the detected component, it indicates that the fiber cutting table 1 has rotated to a preset rotation angle, and the fiber cutting table 1 is controlled to stop rotating. The first photoelectric detection sensor 3 and the second photoelectric detection sensor 4 are switches for controlling the start and stop of the fiber winding power source 2.

[0051] Reference Figure 7 As shown, in this embodiment, in order to further limit the angle of the optical fiber entering the fiber passage 14, a fiber guide wheel 5 is further provided. The fiber guide wheel 5 is arranged between the fiber cutting table 1 and the fiber release equipment. The fiber guide wheel 5 guides the optical fiber into the fiber cutting table 1. The fiber guide wheel 5 presses the optical fiber, changes the running angle of the optical fiber, and enables the optical fiber to enter the fiber passage 14 horizontally.

[0052] Specifically, optical fiber preparation needs to be carried out in a dust-free environment. For the purpose of this embodiment, the automatic fiber cutting device also includes a shell 6, and the shell 6 is covered outside the fiber cutting table 1. The fiber winding power source 2 is fixed on the shell 6. The shell 6 includes a base and a cover body that can be opened and closed. A fiber inlet and a fiber outlet corresponding to the position of the fiber passage 14 are provided on the shell 6. During the process of paying out the optical fiber, the cover body is fastened to the base to provide a relatively closed space, which can not only prevent the optical fiber from being contaminated, but also improve the safety of the device when in use.

[0053] Specifically, a support frame 7 is provided below the shell 6. The support frame 7 is a telescopic support. The support frame 7 can adjust the height of the shell 6, thereby adjusting the height of the fiber cutting table 1, and can be used with sheathing equipment of different heights.

[0054] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
