Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber cutting equipment, and particularly relates to a rapid cutting equipment for optical fibers. Background Art

[0002] An optical fiber is a fiber made of glass or plastic and is used as a material for optical conduction. Optical fiber communication is a quite promising communication technology in practical applications. It has become a very important pillar of modern communication. The capacity of optical fiber communication is dozens of times larger than that of microwave communication. Compared with cable communication or microwave communication, it has many unique advantages. Therefore, optical fiber communication has been widely used. As a transmission channel, the optical fiber must be connected between communication devices. However, the optical fiber is not infinitely long. Therefore, the length of the optical fiber will affect the signal transmission range. So the connection of the optical fiber becomes a very important link in optical fiber communication.

[0003] When the existing optical fiber cutting machine cuts an optical fiber, after a blade made of materials such as cemented carbide forms a preliminary scar on the optical fiber, a force is applied to the optical fiber in a way that makes the preliminary scar grow, so as to cut the optical fiber by splitting. During operations such as replacing the cutting edge component, because the positional relationship between the cutting edge component and the optical fiber or the holding part needs to be adjusted, not only is the process complex, but also the proficiency requirement for the operator is relatively high. And after the optical fiber is split by using the knife to form an initial cut mark on the optical fiber, the cut surfaces of the optical fiber are prone to extrusion with each other, affecting the flatness of the optical waveguide end face after cutting, which brings certain adverse effects to the using process of people. To solve the deficiencies of the existing technology, we propose a rapid cutting equipment for optical fibers. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, through the arranged detection wire, according to the distance difference between the distance detected by the rope displacement sensor for the displacement of the moving slide this time and the initial value of the moving slide, a judgment is made. When the detection wire touches the surface of the optical fiber body, the distance that the moving slide moves is detected by the rope displacement sensor, so as to judge the position and height of the optical fiber body at the position of the detection wire, and further judge the position and height of the optical fiber body. The rope displacement sensor controls the automatic lifting and adjustment of the cutting blade through an electrical signal, which not only adapts to optical fiber bodies of various thicknesses, but also can automatically adjust the cutting blade before each cutting, reducing manual adjustment and improving the cutting efficiency of the optical fiber body.

[0019] 2. In the present invention, while the second clamping block and the second cushion block clamp and fix the optical fiber body, due to the reaction force of the first pushing spring and the second pushing spring, there is a rightward pulling force in the same axial direction as the optical fiber body. Therefore, when the optical fiber body is cut and broken, the optical fiber body is split by the pulling force, improving the flatness of the optical waveguide cross-section of the optical fiber body and the cutting effect of the optical fiber body.

[0020] 3. In the present invention, through the provided lifting groove, while limiting the optical fiber body, when the cutting blade moves from left to right to cut the optical fiber body, affected by the cutting of the cutting blade, the optical fiber body will move upward, causing the cutting blade to only cut the bottom of the optical fiber body, avoiding deformation of the optical fiber body when the cutting blade moves from left to right. If the optical fiber body deforms upward to the right, it will cause the cutting blade to tilt when cutting the optical fiber body, affecting the flatness of the optical waveguide end face after cutting the optical fiber body and improving the cutting effect of the optical fiber body.

[0021] 4. By heating the optical fiber body with a heating plate, the strength of the optical fiber body is reduced, facilitating the cutting of the optical fiber body by the cutting blade, reducing the deformation caused by the cutting blade pressing on the optical fiber body, reducing the damage to the cutting blade, and extending the service life of the cutting blade.

Detailed implementation manners

[0032] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] Example 1, as Figure 1 - Figure 2 , Figure 6 - Figure 8 shown, a rapid cutting device for optical fibers includes a support base 1, a cutting cover 2 is hinged to the side of the support base 1 through a rotating shaft, an optical fiber body 4 is clamped and installed on the top of the support base 1, two limiting components 5 are fixedly installed on the right side of the top of the support base 1, and a cutting component 3 is slidably installed inside the right side of the support base 1;

[0034] The cutting component 3 includes a moving slide 31. A limiting slider 32 is fixedly installed on the left side of the moving slide 31. A pushing block 34 is fixedly installed in the middle of the right side of the moving slide 31. A cutting assembly 35 is fixedly installed in the middle of the moving slide 31. A cable displacement sensor 33 is fixedly installed at one end of the moving slide 31. A fixing block 36 is fixedly installed on one side of the top of the moving slide 31 near the cable displacement sensor 33. A first connecting block 37 is fixedly installed on one side of the top of the fixing block 36. A detection wire 38 is fixedly connected to the top of the first connecting block 37. A second connecting block 310 is fixedly installed on the other side of the top of the fixing block 36. A pressure sensor 39 is rotatably installed inside the second connecting block 310. The pressure sensor 39 is movably sleeved on the outer surface of one end of the detection wire 38. A limiting bead 311 is fixedly installed at one end of the detection wire 38 near the pressure sensor 39. A pressure spring 312 is movably sleeved on the outer surface of one end of the detection wire 38. The pressure spring 312 is located between the pressure sensor 39 and the limiting bead 311.

[0035] Among them, the first connecting block 37 is located on one side of the cable displacement sensor 33, and the height of the first connecting block 37 is higher than the height of the second connecting block 310, and the detection wire 38 is in an inclined state.

[0036] Since the detection wire 38 is in an inclined state, when the pushing block 34 is pushed and the moving slide 31 moves inside the sliding groove 15, when the detection wire 38 contacts the surface of the optical fiber body 4, the distance that the moving slide 31 moves is detected by the cable displacement sensor 33, so as to judge the position and height of the optical fiber body 4 at the position of the detection wire 38, and further judge the position and height of the optical fiber body 4. That is to say, by setting the cable displacement sensor 33, during calibration, it is set that when the detection wire 38 contacts the optical fiber body 4, the detection wire 38 is subjected to a pulling force, the pressure spring 312 is compressed, and the pressure sensor 39 senses the pressure of the pressure spring 312 on it. At this time, the distance of the displacement of the moving slide 31 is detected by the cable displacement sensor 33 and used as the initial value. Subsequently, before cutting the optical fiber body 4, when the pushing block 34 is pushed and the moving slide 31 moves, when the detection wire 38 contacts the side of the optical fiber body 4, according to the difference between the distance of the displacement of the moving slide 31 detected by the cable displacement sensor 33 and the distance of the initial value of the moving slide 31, a judgment is made. When the displacement distance of the moving slide 31 is larger than the initial distance, the cable displacement sensor 33 controls the lifting motor 352 to work through an electrical signal, and the fixed tool block 354 drives the cutting blade 355 to rise to the corresponding value. When the displacement distance of the moving slide 31 is smaller than the initial distance, the cable displacement sensor 33 controls the cutting blade 355 to descend to the corresponding value through an electrical signal, so as to realize the automatic lifting and adjustment of the cutting blade 355, which not only adapts to optical fiber bodies 4 of various thicknesses, but also can automatically adjust the cutting blade 355 before each cutting, reducing manual adjustment and improving the cutting efficiency of the optical fiber body 4.

[0037] The highest point of the first connecting block 37 is higher than the first cushion block 14 and has the same thickness as the first clamping block 23 , so that when the support base 11 and the flip cover 21 are closed, the detection wire 38 and the first connecting block 37 do not affect the closing between the support base 11 and the flip cover 21 .

[0038] like Figure 8 As shown, the cutting assembly 35 includes a supporting tool holder 351, which is fixedly installed in the middle of the movable slide 31, a lifting screw 353 is rotatably installed inside the supporting tool holder 351, a lifting motor 352 is fixedly installed at the bottom of the lifting screw 353, and the lifting motor 352 is fixedly installed at the bottom of the movable slide 31, a fixed knife block 354 is slidably installed inside the supporting tool holder 351, the fixed knife block 354 is threadedly installed on the outer surface of the lifting screw 353, and a cutting blade 355 is fixedly installed on one side of the fixed knife block 354 by two bolts.

[0039] The cutting blade 355 is fixed by two bolts. When the cutting blade 355 needs to be calibrated, one bolt can be loosened lightly first, and the bolt at the other end can be turned to adjust the height of the cutting blade 355 so that the cutting blade 355 is adjusted to a suitable height, and the bolts at both ends are tightened to fix the bolt cutting blade 355.

[0040] Among them, the limit slider 32 is slidably installed inside the guide groove 113, the movable slide 31 is slidably installed under the sliding groove 15, and a fixed plate 18 is fixedly installed on the bottom of the right side of the support base 11, and a support rod 19 is fixedly installed on one side of the fixed plate 18.

One side of the reset spring 110 is fixedly installed on one side of the fixed plate 18, and the other side of the support rod 19 is fixedly installed on the side of the movable slide 31 close to the pull rope displacement sensor 33.

[0041] Among them, the support base 1 includes a support base 11, an optical fiber fixing part 12 is fixedly installed on the left side of the top of the support base 11, the optical fiber body 4 is clamped and installed inside the optical fiber fixing part 12, a first magnet 13 is embedded and installed inside one end of the support base 11, a sliding groove 15 is opened inside the support base 11 away from the side of the optical fiber fixing part 12, a first cushion block 14 is fixedly installed on the top of the support base 11 located on the left side of the sliding groove 15, two limit assemblies 5 are respectively fixedly installed on the left and right sides of the sliding groove 15, a support shaft 16 is fixedly installed on the side of the top of the support base 11 away from the first magnet 13, and a torsion spring 17 is movably sleeved in the middle of the support shaft 16.

[0042] Embodiment 2, as Figure 1 , Figure 3 - Figure 5As shown in the figure, a rapid cutting device for optical fibers is provided. On the right side of the top of the support base 11, a bottom groove 111 is opened. Inside the bottom groove 111, a first sliding base block 118 is slidably installed. On the right side of the first sliding base block 118, a first side plate 123 is fixedly installed. On the top of the first sliding base block 118, a second cushion block 120 is fixedly installed. At both ends of the left side of the bottom of the first sliding base block 118, first clamping grooves 119 are opened. On both sides of the bottom of the first sliding base block 118, first sliding blocks 121 are fixedly installed. On the left side of both first sliding blocks 121, first pushing springs 122 are fixedly installed.

[0043] As Figure 4 shown, on both sides inside the bottom groove 111, first limiting grooves 112 are opened. The first sliding blocks 121 are slidably installed inside the first limiting grooves 112, and the left side of the first pushing spring 122 is fixedly installed on the left side of the first limiting groove 112. The first side plate 123 is movably sleeved on the right side of the support base 11. On both sides of the top of the support base 11, first pressing blocks 116 are movably sleeved. The first pressing blocks 116 are located between the sliding groove 15 and the bottom groove 111. On the right side of the lower end of the first pressing block 116, a bottom barb 117 is fixedly installed. On both sides of the right end of the support base 11, first moving cavities 114 are opened. The first pressing blocks 116 and the bottom barbs 117 are movably installed inside the first moving cavities 114. At the bottom of the first pressing block 116, a first clamping spring 115 is fixedly installed. The bottom of the first clamping spring 115 is connected to the inner bottom surface of the first moving cavity 114. The bottom barb 117 is movably installed inside the bottom groove 111 and is clamped and installed at the bottom of the first clamping groove 119. The right side of the bottom barb 117 is an inclined surface. Inside the support base 11, on the left side below the sliding groove 15, a guide rail groove 113 is opened.

[0044] Before use, by pressing the first side plate 123, the first pushing spring 122 is compressed, and the first sliding base block 118 moves to the left side of the bottom groove 111. Using the inclined surface at the top of the bottom barb 117, the first clamping spring 115 is compressed, and through the reaction force of the first clamping spring 115, the bottom barb 117 is clamped inside the first clamping groove 119. Similarly, by pressing the second side plate 214, the second pushing spring 217 is compressed, and the top barb 28 is clamped inside the second clamping groove 215. When closing the support base 11 and the flip cover 21, one end of the support block 29 presses against one side of the first pressing block 116, and the other end of the support block 29 presses the second pressing block 27, so that both the second clamping spring 26 and the first clamping spring 115 are in a compressed state. At this time, the bottom barb 117 and the top barb 28 move to both sides and respectively disengage from the inside of the first clamping groove 119 and the second clamping groove 215, so that while the second clamping block 212 and the second cushion block 120 clamp and fix the optical fiber body 4, through the reaction forces of the first pushing spring 122 and the second pushing spring 217, there is a right-side pulling force in the same axial direction as the optical fiber body 4. Then, when the optical fiber body 4 is cut and broken, the optical fiber body 4 is split by the pulling force, improving the flatness of the light guide section of the optical fiber body 4 and the cutting effect of the optical fiber body 4.

[0045] Such as Figure 5As shown in the figure, the cutting cover 2 includes a flip cover 21. The bottom of the flip cover 21 is rotatably installed on the outer surface of the support shaft 16. The torsion spring 17 is located between the support base 11 and the flip cover 21. A second magnet 22 is fixedly installed at the top of the flip cover 21. The position of the second magnet 22 corresponds to that of the first magnet 13 and is magnetically connected to the first magnet 13.

A second limit groove 211 is formed on the right side of the flip cover 21. Support blocks 29 are movably sleeved at both ends on the right side of the flip cover 21. The support blocks 29 are located on the top of the first pressing block 116. A second moving cavity 25 is formed inside the flip cover 21. A second pressing block 27 is movably sleeved inside the second moving cavity 25. The second pressing block 27 is movably installed on one side of the support block 29. A top barb 28 is fixedly installed on the right side of the second pressing block 27, and the top of the top barb 28 is beveled. A second clamping spring 26 is fixedly installed on one side of the second pressing block 27. One end of the second clamping spring 26 is fixedly installed on the side of the second moving cavity 25. The second pressing block 27 and the top barb 28 are movably installed inside the second moving cavity 25. Second limit grooves 211 are formed on both sides inside the top groove 210. A second sliding base block 213 is slidably installed inside the top groove 210. A second side plate 214 is fixedly installed on the right side of the second sliding base block 213. A second clamping block 212 is fixedly installed on one side of the second sliding base block 213. Second clamping grooves 215 are formed at both ends on the other side of the second sliding base block 213 away from the second clamping block 212. Second sliding blocks 216 are fixedly installed at both ends on the side of the second sliding base block 213 away from the second clamping block 212. The second sliding blocks 216 are slidably installed inside the second limit grooves 211. A second pushing spring 217 is fixedly installed on one side of the second sliding block 216. The other end of the second pushing spring 217 is fixedly installed on the side of the second limit groove 211.

[0046] Among them, the position of the first clamping block 23 corresponds to that of the first cushion block 14, and the position of the second clamping block 212 corresponds to that of the second cushion block 120. The top barb 28 is snap-fitted inside the second clamping groove 215.

[0047] With the function of the support block 29, when the support base 11 and the flip cover 21 are closed, affected by the support block 29, the second pressing block 27 and the first pressing block 116 move to both sides, causing the reaction force of the first pushing spring 122 to push the second cushion block 120 to move to the right, and the reaction force of the second pushing spring 217 to push the second clamping block 212 to move to the right. When the flip cover 21 is opened, the support block 29 is not under extrusion force, and the second clamping spring 26 resets, causing the top barb 28 to be snap-fitted inside the second sliding block 216 to fix the second sliding base block 213.

[0048] Example 3, asFigure 1 and Figure 9 As shown in Figure 9 , a rapid cutting device for an optical fiber, the limiting component 5 includes a heating frame 51. A lifting groove 52 is formed at the top of the heating frame 51. The lifting groove 52 is movably sleeved on the outer surface of the optical fiber body 4.

[0049] By setting the lifting groove 52, while limiting the optical fiber body 4, when the cutting blade 355 moves from left to right to cut the optical fiber body 4, affected by the cutting of the cutting blade 355, the optical fiber body 4 will move upward, so that the cutting blade 355 will only cut the bottom of the optical fiber body 4, avoiding the deformation of the optical fiber body 4 when the cutting blade 355 moves from left to right, and the optical fiber body 4 deforms upward to the right, resulting in the inclination of the cutting blade 355 when cutting the optical fiber body 4, affecting the flatness of the optical waveguide end face after cutting the optical fiber body 4. At the same time, the heating plate 53 heats the optical fiber body 4 to reduce the strength of the optical fiber body 4, facilitating the cutting of the optical fiber body 4 by the cutting blade 355, reducing the deformation caused by the cutting blade 355 pressing on the optical fiber body 4, reducing the damage of the cutting blade 355, and extending the service life of the cutting blade 355.

[0050] It should be noted that the present invention is a rapid cutting device for an optical fiber. When in use, the optical fiber body 4 is placed inside the optical fiber fixing member 12 for fixation. The right end of the optical fiber body 4 is clamped inside the two limiting components 5 on the right side. Press the first side plate 123 to make the first sliding base block 118 move to the left inside the bottom groove 111. The first sliding base block 118 pushes the inclined surface of the bottom barb 117, compressing the first clamping spring 115. The bottom barb 117 and the first pressing block 116 descend. When the bottom barb 117 reaches the bottom of the first clamping groove 119, through the reaction force of the first clamping spring 115, the bottom barb 117 is clamped inside the first clamping groove 119 to fix the first sliding base block 118 and the second cushion block 120. At this time, the first sliding block 121 moves to the left, making the first pushing spring 122 in a compressed state.

[0051] Subsequently, press the second side plate 214 to make the second sliding base block 213 move to the left inside the top groove 210. The second sliding base block 213 presses against the inclined surface of the top barb 28, compressing the second clamping spring 26, causing the second pressing block 27 and the top barb 28 to descend. When the second clamping groove 215 reaches the side of the top barb 28, through the reaction force of the second clamping spring 26, the top barb 28 is clamped inside the second clamping groove 215. At this time, the second sliding block 216 moves to the left inside the second limiting groove 211, and the second pushing spring 217 is in a compressed state.

[0052] During cutting, the flip cover 21 is closed, so that the first magnet 13 and the second magnet 22 are magnetically connected and fixed to each other, the pressure hammer 24 and the first cushion block 14 clamp one end of the optical fiber body 4 at the left end of the sliding groove 15, the second cushion block 120 and the second clamping block 212 clamp one end of the optical fiber body 4 at the right end of the sliding groove 15, one end of the support block 29 is pressed to one side of the first pressing block 116, and the other end of the support block 29 presses the second pressing block 27, so that the second clamping spring 26 and the first clamping spring 115 are both in a compressed state, and at this time, they are separated from the first clamping spring 26 and the first clamping spring 115. The inside of the connection groove 119 and the second clamping groove 215 allows the second clamping block 212 and the second cushion block 120 to clamp and fix the optical fiber body 4. At the same time, through the reaction force of the first push spring 122 and the second push spring 217, there is a right-side pulling force that is the same as the axial direction of the optical fiber body 4, so that the reaction force of the first push spring 122 pushes the second cushion block 120 to move to the right side, and the reaction force of the second push spring 217 pushes the second clamping block 212 to move to the right side. The heating plate 53 works to heat the optical fiber body 4.

[0053] During cutting, by toggling the push block 34, the limit slider 32 on the side of the movable slide 31 slides to the left inside the guide groove 113. When the detection wire 38 on the top of the movable slide 31 contacts the optical fiber body 4, the detection wire 38 is subjected to tension, the pressure spring 312 is compressed, and the pressure sensor 39 senses the pressure of the pressure spring 312 on it, and the difference between the displacement distance of the movable slide 31 and the initial value of the movable slide 31 is detected by the pull-wire displacement sensor 33, and a judgment is made. When the displacement distance of the movable slide 31 is larger than the initial distance, the pull-wire displacement sensor 33 controls the lifting motor 352 to work through an electrical signal, and the fixed knife block 354 drives the cutting blade 355 to rise to the corresponding value. When the displacement distance of the movable slide 31 is smaller than the initial distance, the pull-wire displacement sensor 33 controls the lifting motor 352 to work through an electrical signal, and the fixed knife block 354 drives the cutting blade 355 to rise to the corresponding value. The signal controls the cutting blade 355 to drop to the corresponding value, and then pushes the pushing block 34 in the opposite direction, so that the movable slide 31 moves to the right at the bottom of the sliding groove 15, so that the cutting blade 355 cuts the bottom of the optical fiber body 4, and the cutting blade 355 forms a preliminary scar on the bottom of the optical fiber body 4. Subsequently, the pressure hammer 24 applies force to the optical fiber body 4 in the form of growing the preliminary scar on the optical fiber body 4, and through the reaction force of the first push spring 122 and the second push spring 217, the second clamping block 212 and the second cushion block 120 axially break the optical fiber body 4. At the same time, the first sliding base block 118 and the second cushion block 120 move to the right side of the bottom groove 111, and the second sliding base block 213 and the second clamping block 212 move to the right side inside the top groove 210, to assist in breaking the optical fiber body 4 and achieve cutting.
