Description

Technical Field

[0001] This invention relates to the field of optical cable manufacturing technology, and in particular to an automatic fiber cutting device. Background Technology

[0002] In optical cable manufacturing, fiber coating is one of the important processing techniques. Fiber coating involves preparing loose tubes or loose tubes on the outside of the optical fiber to protect it. During fiber coating, the optical fiber in the fiber reel is introduced into the coating machine through a fiber laying device. The coating machine extrudes plastic to form loose tubes or loose tubes on the outside of the optical fiber. Depending on the production order requirements, the length of fiber coating is generally between 2km and 24km. However, the optical fiber in the fiber reel is usually 24km or 48km long. Therefore, a reel of optical fiber can complete the coating process for multiple lengths. After completing the coating process for one section, the optical fiber needs to be cut.

[0003] Existing fiber cutting devices directly cut the optical fiber. Since the fiber laying equipment provides a certain tension during the fiber laying process, after the fiber is suddenly cut, the taut fiber will experience jumpers. These jumpers will become entangled in the fiber laying equipment, affecting its continued use. At the same time, when the fiber laying equipment is in the process of high-speed laying and the fiber is suddenly cut, the fiber laying equipment cannot stop immediately and requires a buffer shutdown process. During this process, fiber will continue to be laid out. After the laid fiber is unraveled, it cannot be wound back into the fiber optic reel. The tail fiber needs to be cut off for the next use, resulting in fiber waste. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the fiber laying equipment cannot stop immediately after the fiber is cut, resulting in fiber waste. The present invention provides an automatic fiber cutting device that can clamp the fiber end immediately when the fiber is cut to prevent fiber jump or rebound. In addition, it can drive the fiber to rotate and wind up the excess fiber to avoid fiber waste.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic fiber shearing device, characterized in that it comprises:

[0006] A fiber cutting table includes a first fiber cutting block and a second fiber cutting block. A fiber passage is provided between the first fiber cutting block and the second fiber cutting block. A first pressing block and a first fiber cutting blade are provided on the side of the first fiber cutting block facing the fiber passage. A second pressing block and a second fiber cutting blade are provided on the side of the second fiber cutting block facing the fiber passage. The first pressing block and the second pressing block are positioned correspondingly, and the first fiber cutting blade and the second fiber cutting blade are positioned correspondingly.

[0007] The fiber cutting table also includes a fiber cutting power source, which drives the first fiber cutting block and the second fiber cutting block to move toward or in opposite directions. When the fiber cutting power source drives the first fiber cutting block and the second fiber cutting block to move toward each other, the first fiber cutting blade and the second fiber cutting blade cooperate to complete the fiber cutting action. At the same time, the first clamping block and the second clamping block hold the head end of the cut optical fiber.

[0008] A fiber winding power source is connected to the fiber cutting table. After the fiber cutting table completes the fiber cutting action, the fiber winding power source drives the fiber cutting table to rotate in the forward direction. The first pressure block and the second pressure block clamp the cut optical fiber and wind it around the outer periphery of the fiber cutting table. After the fiber laying equipment stops, the fiber winding power source drives the fiber cutting table to rotate in the reverse direction, and retracts the optical fiber into the fiber laying equipment.

[0009] In one embodiment of the present invention, a first arc surface is provided on the side of the first fiber shearing block away from the fiber passage, and a second arc surface is provided on the side of the second fiber 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 the first arc surface and the second arc surface extend in the direction of the fiber passage to form 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, a rounded chamfer is provided at the ends of the first arc surface and the second arc surface near the fiber channel.

[0012] In one embodiment of the present invention, the fiber shearing power source includes:

[0013] A cylinder, wherein the cylinder body is fixed on the first fiber shearing block, and the piston rod of the cylinder is connected to the second fiber shearing block;

[0014] The guide assembly includes a fixed base fixed to the first fiber shearing block, a guide rod disposed on the fixed base, and a bearing seat fixed to the second fiber shearing block, wherein the guide rod extends toward the second fiber shearing block and passes through the bearing seat.

[0015] In one embodiment of the present invention, the fiber winding power source includes:

[0016] The rotating shaft is connected to the fiber shearing table;

[0017] An electric slip ring is provided at the end of the rotating shaft. The rotary joint of the electric slip ring is connected to the rotating shaft. The rotary joint of the electric slip ring is connected to the cylinder of the fiber cutting power source through an air pipe. The fixed joint of the electric slip ring is connected to the air supply equipment through an air pipe.

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

[0019] In one embodiment of the present invention, it further includes: a photoelectric detection sensor, the photoelectric detection sensor being used to define the initial position and rotational 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 to a horizontal channel;

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

[0022] In one embodiment of the present invention, it further includes: a fiber guide wheel, which is disposed between the fiber cutting table and the fiber laying device, and the fiber guide wheel guides the optical fiber into the fiber cutting table.

[0023] In one embodiment of the present invention, a housing is further included, which covers the fiber cutting table. The housing includes a base and an openable cover. A fiber inlet and a fiber outlet corresponding to the fiber passage position are provided on the housing. The fiber winding power source is fixed on the housing.

[0024] In one embodiment of the present invention, a support frame is further included, disposed below the housing, the support frame being a telescopic bracket, and the support frame being capable of adjusting the height of the housing.

[0025] The technical solution of the present invention has the following advantages over the prior art:

[0026] The automatic fiber cutting device of the present invention includes a fiber cutting table comprising a first fiber cutting block and a second fiber cutting block. A pressure block and a fiber cutter are provided at corresponding positions of the first and second fiber cutting blocks. The pressure block and the fiber cutter are set to move synchronously. While the fiber cutter cuts the optical fiber, the pressure block can clamp and fix the cut end of the optical fiber, which can prevent the fiber jumper from being stretched under tension and prevent the optical fiber from flying away and getting tangled on the fiber laying equipment.

[0027] Furthermore, after the fiber cutting is completed, since the fiber laying equipment cannot stop rotating immediately, excess optical fiber will continue to be released. The automatic fiber cutting device of this invention is equipped with a winding power source that drives the fiber cutting table to rotate in the forward direction after the fiber cutting table completes the fiber cutting action. Since the end of the optical fiber is clamped and fixed, excess optical fiber can be wound around the outer periphery of the fiber cutting table during the rotation of the fiber cutting table. After the fiber laying equipment stops, the winding power source drives the fiber cutting table to rotate in the reverse direction, and the fiber laying equipment also reverses at the same time, which can return the optical fiber wound outside the fiber cutting table back into the fiber laying equipment, thus avoiding the waste of optical fiber.

[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 and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0038] In the field of optical cable manufacturing, fiber cutting devices are generally used in conjunction with fiber laying equipment. In practice, the inventors of this application have discovered that when using existing automatic fiber cutting devices to cut optical fibers, the fiber laying equipment provides a certain tension during the laying process. When the fiber is suddenly cut, the taut fiber under tension will experience jumpers, which will become entangled in the laying equipment, affecting its continued use. At the same time, during the high-speed laying process, when the fiber is cut, the laying equipment cannot stop immediately and requires a buffer shutdown process. During this process, fiber will continue to be laid out. After the laid fiber is unraveled, it cannot be wound back into the fiber optic reel. The tail fiber needs to be cut off for the next use, resulting in fiber waste.

[0039] To address the aforementioned problems, this invention provides an automatic fiber cutting device that can clamp the fiber end immediately upon cutting the fiber to prevent fiber skipping or rebound. Furthermore, it can rotate the fiber to wind up and recycle excess fiber, thus avoiding fiber waste.

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

[0041] Reference Figure 1 As shown, this invention discloses an automatic fiber cutting device used in conjunction with a fiber laying device. Located at the rear end of the fiber laying device, it includes a fiber cutting table 1 and a fiber winding power source 2. The fiber, after being laid out from the fiber laying device, passes through the fiber cutting table 1. During normal laying, the fiber cutting table 1 does not affect the fiber laying. When it is necessary to cut the fiber, the fiber cutting table 1 cuts the fiber and can clamp the fiber end near the fiber laying device. At this time, the fiber laying device receives a stop command. However, since the laying device rotates at high speed, the laying process needs to be stopped slowly. Therefore, excess fiber still flows from the laying device. In the fiber deployment process, 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 in the forward direction. Since the fiber end is clamped and fixed, during the rotation of the fiber cutting table 1, excess fiber can be wound around the outer circumference of the fiber cutting table 1. After the fiber deployment equipment stops completely, the fiber winding power source 2 will also stop rotating to prevent the fiber from being pulled off. Finally, the fiber winding power source 2 is controlled to drive the fiber cutting table 1 to rotate in the reverse direction, and the fiber deployment equipment also reverses at the same time, which can return the fiber wound outside the fiber cutting table 1 back into the fiber deployment equipment, thus avoiding fiber waste.

[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. The fiber cutting power source 13 drives the first fiber cutting block 11 and the second fiber cutting block 12 to move in opposite directions. When the fiber cutting power source drives the first fiber cutting block 11 and the second fiber cutting block 12 to move in opposite directions, a fiber-passing channel 14 is provided between the first fiber cutting block 11 and the second fiber cutting block 12 to introduce the optical fiber into the fiber-passing channel 14 and pass through the fiber-passing channel 14. During normal cable laying, 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 in opposite directions, 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 pressure block 111 and a first fiber cutter 112 are provided on the side of the first fiber cutting block 11 facing the fiber channel 14, and a second pressure block 121 and a second fiber cutter 122 are provided on the side of the second fiber cutting block 12 facing the fiber channel 14. The first pressure block 111 and the second pressure block 121 are positioned correspondingly, and the first fiber cutter 112 and the second fiber cutter 122 are positioned correspondingly. The first fiber cutter 112 and the second fiber cutter 122 cooperate to complete the fiber cutting action. At the same time, the first pressure block 111 and the second pressure block 121 clamp the end of the cut optical fiber, which can prevent the taut optical fiber from jumping out under tension and prevent the optical fiber from flying away and getting tangled in the fiber laying equipment.

[0044] It should be noted that due to the characteristics of optical fibers, they have high tensile strength when bent, but they are easily broken after being bent. Therefore, when the fiber cutting table 1 of the present invention is winding the optical fiber, it is necessary to prevent the optical fiber from being bent. To achieve this effect, in this embodiment, the first fiber cutting block 11 is provided with a first arc surface 113 on the side away from the fiber passage 14, and the second fiber cutting block 12 is provided with a second arc surface 123 on the side 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. The first arc surface 113 and the second arc surface 123 extend towards the fiber passage 14 and 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, which can minimize the bending angle of the optical fiber and prevent the optical fiber from being broken.

[0045] Furthermore, 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. The ends of the first arc surface 113 and the second arc surface 123 near the fiber passage 14 are provided with arc chamfers 15, which can also minimize the bending angle of the optical fiber and 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 restrict the lateral movement of the optical fiber and prevent the optical fiber from sliding out from both sides of the fiber cutting table 1.

[0047] In this embodiment, the fiber-cutting power source 13 is configured to drive the first fiber-cutting block 11 and the second fiber-cutting block 12 to move in opposite directions or in the same direction. (Refer to...) Figure 3 As shown, the fiber-cutting power source 13 includes a cylinder 131 and a guide assembly 132. 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 to 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 to 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 methods can also be provided. The guide assembly 132... Component 132 includes a fixed base fixed on the first fiber cutting block 11, a guide rod disposed on the fixed base, and a bearing seat fixed on the second fiber cutting block 12. The guide rod extends toward the second fiber cutting block 12 and passes through the bearing seat. The guide component 132 can precisely limit the relative movement direction of the first fiber cutting block 11 and the second fiber cutting block 12, so that the first fiber cutting blade 112 and the second fiber cutting blade 122 can precisely 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, refer 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 cutting table 1. When the rotating shaft 23 rotates, it can drive the fiber cutting 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 to it. Since the fiber-cutting power source 13 is set on the fiber-cutting table 1, it needs to rotate synchronously with the fiber-cutting table 1. When rotating, the air pipe is easy to get tangled on the fiber-cutting table 1, causing the fiber-cutting table 1 to be unable to rotate. To solve this problem, the fiber-winding power source 2 also includes a pneumatic slip ring 24. The pneumatic slip ring 24 is set at the end of the rotating shaft 23. The rotary joint of the pneumatic slip ring 24 is connected to the rotating shaft 23. The rotary joint can rotate synchronously with the rotating shaft 23. The rotary joint of the pneumatic slip ring 24 is connected to the cylinder 131 of the fiber-cutting power source 13 through an 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, so the air pipe will not get tangled. The fixed joint of the pneumatic slip ring 24 is connected to the air supply device through an air pipe. 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 channel 14. During normal cable laying, it is necessary to ensure that the optical fiber does not come into contact with the first fiber cutting block 11 and the second fiber cutting block 12. Simultaneously, after the fiber laying equipment completely stops, the fiber-driven power source 2 also needs to stop rotating. This necessitates limiting the initial position and rotation angle of the entire fiber cutting table 1, referring to... Figure 1 As shown, in this embodiment, when the first photoelectric detection sensor 3 is used to limit the initial position of the fiber cutting table 1, a corresponding detection component is set on the fiber cutting table 1. When the first photoelectric detection sensor 3 detects the detection component, it indicates that the fiber cutting table 1 is now in a horizontal position, and the fiber passage 14 set in the fiber cutting table 1 is a horizontal channel. Similarly, when the second photoelectric detection sensor 4 is used to limit the rotation position of the fiber cutting table 1, when the first photoelectric detection sensor 3 detects the detection 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 the switches that control 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 at which the optical fiber enters the fiber passage 14, a fiber guide wheel 5 is also provided. The fiber guide wheel 5 is located between the fiber cutting table 1 and the fiber laying device. The fiber guide wheel 5 guides the optical fiber into the fiber cutting table 1. The fiber guide wheel 5 presses against the optical fiber and changes the running angle of the optical fiber so that the optical fiber can enter the fiber passage 14 horizontally.

[0052] Specifically, optical fiber fabrication needs to be carried out in a dust-free environment. For this embodiment, the automatic fiber cutting device also includes a housing 6, which covers the fiber cutting table 1. The fiber winding power source 2 is fixed on the housing 6. The housing 6 includes a base and an openable cover. The housing 6 has a fiber inlet and a fiber outlet corresponding to the position of the fiber channel 14. During the fiber laying process, the cover is fastened to the base, which can provide a relatively closed space, which can not only prevent the optical fiber from being contaminated, but also improve the safety of the device during use.

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

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
