Description

Technical Field

[0001] This invention relates to the field of optical fiber fusion splicing technology, specifically to a hollow optical fiber fusion splicer with a windproof cover and a pressure foot linkage mechanism. Background Technology

[0002] A fiber optic fusion splicer is a specialized device for connecting optical fibers. It is mainly used to fuse two optical fibers together to achieve lossless transmission of optical signals. The working principle of a fiber optic fusion splicer is to melt and precisely align the cores of two optical fibers under high temperature conditions, and then fuse them together to enable lossless transmission of optical signals. In the field of fiber optic communication network construction and maintenance, fiber optic fusion splicers are core equipment to ensure the quality of fiber optic connections and are widely used in diverse scenarios such as FTTH home installation, backbone network optical cable repair, and outdoor high-altitude operations.

[0003] The process of fiber optic fusion splicing involves first stripping the fiber, then cutting the stripped fiber, placing the cut fiber in the V-groove and placement table of the fiber optic fusion splicer, pressing the stripped portion of the fiber with a clamping plate on the placement table, then pressing the bare fiber in the V-groove with a control foot, closing the windproof cover, performing discharge splicing after core alignment, opening the windproof cover, opening the clamping foot and clamping plate, and removing the welded fiber.

[0004] There are currently two technical issues to be resolved:

[0005] a. The preparation of optical fibers requires the pressing of the clamping feet each time, which makes optical fiber splicing inconvenient and affects the efficiency of optical fiber splicing operation.

[0006] b. The V-groove in the fiber optic fusion splicer serves to guide and position the fiber during the fiber optic splicing process, ensuring that the two fiber optic splicing ends are aligned under the action of the motor and the V-groove. The inner corner of the V-groove may accumulate dirt or dust during frequent use of the fiber, which can affect the placement of the fiber and even its alignment and splicing. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention proposes a hollow fiber fusion splicer with a windproof cover and a pressure foot linkage mechanism. This invention places the V-groove on the upper pressure foot's surface, allowing the V-groove to position and clamp the fiber. The downward-facing opening of the V-groove causes impurities at the V-groove angle to fall off naturally, preventing residue and making fiber positioning and clamping more stable. After the drive belt moves along the fiber, debris and other impurities on the outer wall of the belt are scraped away, ensuring the belt's cleanliness and preventing residual impurities from affecting fiber placement. This makes fiber placement more stable, fiber positioning and clamping more stable, and ultimately, splicing more stable.

[0011] Preferably, a replacement groove is provided through the bottom of the lower square groove from left to right; a replacement box slides in the replacement groove; a scraper block is connected to the bottom wall of the replacement box via a replacement spring; and the scraper block slides up and down on the inner wall of the replacement box.

[0012] Preferably, the inner wall of the arc-shaped groove is provided with a tooth groove corresponding to the position of the driving tooth; the bottom of the tooth groove is connected to the driving tooth through a driving spring; the driving tooth is provided with a first inclined surface facing upward.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention places the V-groove on the upper pressure foot surface, enabling the V-groove to position and clamp the optical fiber. The downward-facing opening of the V-groove allows impurities at the V-groove angle to fall off naturally, preventing residue and making the positioning and clamping of the optical fiber more stable. After the transmission belt moves, debris and other impurities on the outer wall of the transmission belt are scraped away, ensuring the cleanliness of the outer wall of the transmission belt and preventing residual impurities from affecting the placement of the optical fiber. This makes the placement of the optical fiber more stable, the limiting and clamping of the optical fiber more stable, and the fusion splicing more stable.

[0020] 2. Because the unidirectional block is inserted into the slot, the first roller can only rotate in one direction within the first rotating hole. This allows the transmission belt to only perform unidirectional transmission, ensuring that the outer wall of the transmission belt used to support the optical fiber is cleaned by the scraping block, thus improving the cleaning effect of the outer wall of the transmission belt.

[0021] 3. Because the diameter of the third rotating wheel is much larger than that of the second rotating roller, the second rotating roller rotates far more than one revolution for every one revolution of the drive gear, resulting in a longer travel distance for the transmission belt. This allows the upper outer wall of the transmission belt to be replaced, improving the cleanliness of the outer wall of the transmission belt in contact with the optical fiber.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 14 As shown, the present invention includes the following embodiments:

[0040] Example 1 ( Figure 1-4A hollow fiber fusion splicer with a windproof cover and a pressure foot linkage mechanism includes a body 1 and a windproof cover 2 disposed on the upper port of the body 1; the body 1 is provided with two electrode rods (not shown in the figure) and two placement platforms (not shown in the figure); two lower pressure members 11 are disposed on one side of the two placement platforms close to each other; corresponding upper pressure members 21 are disposed above the two lower pressure members 11; an upper linkage frame 22 is fixedly connected to the inner side of the windproof cover 2; the lower end of the upper linkage frame 22 is hinged to the upper end surface of the body 1; the upper surface of the body 1 and The lower linkage frame 23 is hinged to the inner side of the upper linkage frame 22; the upper linkage frame 22 is hinged to the two sides of the linkage bar 24 with linkage groove 241; the linkage bar 25 is movably connected in the linkage groove 241; the linkage bar 25 is fixedly connected to the two sides of the lower linkage frame 23; the lower linkage frame 23 is fixedly connected to the inner side of the upper pressure seat 26; the upper pressure member 21 is elastically slidably connected to the lower surface of the upper pressure seat 26; the upper surface of the lower pressure member 11 is provided with a V-shaped groove 111 facing upward; the upper pressure member 21 can press the optical fiber into the V-shaped groove 111 on the upper surface of the lower pressure member 11.

[0041] Before splicing the optical fibers, the outer sheath of the optical fiber is stripped off, then the coating on the exposed surface of the optical fiber is scraped off, and the exposed optical fiber is cut to form a flat end face. Opening the windproof cover 2 causes the upper linkage frame 22 to flip upwards. The lower end of the upper linkage frame 22 is hinged to the upper surface of the body 1, allowing the windproof cover 2 to open smoothly. After the windproof cover 2 flips the upper linkage frame 22 upwards, the upper linkage frame 22 pulls the linkage bar 24 upwards. The linkage groove 241 on the linkage bar 24 passes through the linkage... The moving rod 25 and the linkage rod 25 are fixedly connected to the lower linkage frame 23. Therefore, as the upper linkage frame 22 moves upward, the linkage bar 24 will pull the linkage rod 25 upward. The linkage rod 25 will cause the lower linkage frame 23 to flip upward. During the upward flipping of the lower linkage frame 23, the upper pressure seat 26 will flip upward simultaneously. The upper pressure seat 26 will cause the elastically sliding upper pressure member 21 to disengage from the lower pressure member 11. Then, the fiber optic cable with its sheath is placed on the placement table, and the exposed fiber optic cable is placed on the lower pressure member. 11. Then, press the clamping plate on the placement platform to press the outer wall of the fiber optic ribbon. Then, control the windproof cover 2 to flip down and close. During the downward flipping of the windproof cover 2, the upper linkage frame 22 will also flip down. The upper linkage frame 22 and the windproof cover 2 will flip around the lower end of the upper linkage frame 22. During the downward flipping of the upper linkage frame 22, the linkage bar 24 will move downward. During the downward movement of the linkage bar 24, the linkage rod 25 in the linkage groove 241 will move downward. The upper linkage frame 22 will squeeze the lower linkage frame. When 23 is flipped downwards, the lower linkage 23 will drive the upper pressure seat 26 to flip downwards. The upper pressure seat 26 will drive the upper pressure component 21 to press the optical fiber onto the upper surface of the lower pressure component 11, thus pressing the optical fiber. Then, the placement stage is controlled to drive the optical fiber to perform core alignment. Next, the electrode rod is controlled to be energized to fuse the optical fiber. After the optical fiber is fused, the windproof cover 2 is controlled to flip upwards again. The windproof cover 2 will drive the upper pressure component 21 away from the lower pressure component 11. Then, the clamping plate on the placement stage is opened, the fused optical fiber is removed, and the windproof cover 2 is closed.

[0042] In this embodiment, the cooperation between the windproof cover 2 and the upper pressure component 21 saves the fiber placement process and also serves the purpose of wind protection. The hinge positions of the upper linkage frame 22 and the lower linkage frame 23 can be lubricated with grease to avoid linkage jamming. The elastic element in the upper pressure seat 26 can be replaced periodically. By connecting the upper pressure component 21 to the windproof cover 2, the upper pressure component 21 can release the pressure on the fiber as the windproof cover 2 is opened, and the upper pressure component 21 can also press the fiber as the windproof cover 2 is opened, thereby facilitating fiber optic splicing operations and improving fiber optic splicing efficiency.

[0043] Example 2 ( Figure 5-14A hollow fiber fusion splicer with a windproof cover and pressure foot linkage mechanism includes a body 1 and a windproof cover 2 hinged to the upper port of the body 1; the body 1 is internally provided with two electrode rods (not shown in the figure) and two placement platforms (not shown in the figure); the two placement platforms are provided with two L-shaped lower pressure feet 3 on one side close to each other; the windproof cover 2 is internally connected to a detachable (meaning it can be separated and installed using bolts) upper pressure platform 4; the lower surface of the upper pressure platform 4 is provided with an upper pressure groove 41; An upper pressure foot 5 is slidably connected within the upper pressure groove 41; the upper surface of the upper pressure foot 5 is connected to the bottom of the upper pressure groove 41 by an upper spring 51; an upper square groove 52 penetrating the front and rear sides is provided in the middle of the lower surface of the upper pressure foot 5; a V-groove 53 is provided along the left and right sides of the lower surface of the upper pressure foot 5; the included angle of the V-groove 53 penetrates the bottom of the upper square groove 52; the thickness of the upper end of the lower pressure foot 3 corresponds to the thickness of the upper square groove 52, and the upper end of the lower pressure foot 3 can enter the upper square groove 52.

[0044] After stripping, decoating, cutting, and wiping the optical fiber, open the windproof cover 2. The upper pressure plate 4 inside the windproof cover 2 moves the upper pressure foot 5 away from the lower pressure foot 3. As the exposed part of the optical fiber is placed on the upper end of the lower pressure foot 3, control the windproof cover 2 to flip downwards and close. The windproof cover 2 will move the upper pressure plate 4 closer to the lower pressure foot 3, and the upper pressure plate 4 will move the upper pressure foot 5 closer to the lower pressure foot 3. Since the lower surface of the upper pressure foot 5 is provided with an upper square groove 52 and a V-groove 53, the upper end of the lower pressure foot 3 can move relative to it and enter into the upper square groove 52. The upper end of the lower pressure foot 3 will drive the optical fiber into the V-groove 53. As the upper pressure foot 5 continues to move upwards, the V-groove on the lower surface of the upper pressure foot 5... 53 can guide and limit the optical fiber, causing it to gradually approach the angle of the V-groove 53. Ultimately, the optical fiber is pressed firmly into the angle of the V-groove 53, achieving fiber compression. It's worth noting that the pressure of the upper pressure foot 5 on the optical fiber comes from the upper spring 51. The upper pressure foot 5 is elastically slidably connected within the upper pressure groove 41, so the optical fiber is not completely compressed. Therefore, the optical fiber can move along the length direction with the placement stage, achieving contact and mating between the optical fibers. Next, the core alignment work is performed. To facilitate core alignment, the upper pressure stage 4 can be fixed to the windproof cover 2 via a horizontal electric push rod, and the lower pressure foot 3 can be fixed to the first horizontal electric push rod via a vertical electric push rod. The electric push rod is then fixedly connected to the body 1, so the lower pressure foot 3 can squeeze the optical fiber and drive the upper pressure foot 5 to move up and down. The lower pressure foot 3 can also drive the upper pressure foot 5 to move back and forth, changing the position of the optical fiber in the vertical and back and forth directions. The horizontal electric push rod of the upper pressure table 4 extends and retracts with the extension and retraction of the first electric push rod, changing the position of the optical fiber in the back and forth direction. In this way, the core alignment is successfully achieved. The core alignment mechanism can also adopt the mechanism in the prior art. The core alignment process is the prior art and is not within the scope of protection of this invention. This invention protects the positioning, limiting and pressing of the optical fiber. During the pressing process, the upper pressure foot 5 will overcome the elastic force of the upper spring 51 and partially retract into the upper pressure groove 41, completing the process. After the optical fibers are paired, they undergo final fusion splicing. The fibers are pressed and positioned by the upper pressure foot 5 and the lower pressure foot 3, facilitating fiber core alignment and splicing. After splicing, the windproof cover 2 is opened, moving the upper pressure foot 5 away from the lower pressure foot 3, releasing the fiber's restriction and pressure. The upper pressure foot 5, pushed by the upper spring 51, moves away from the bottom of the upper pressure groove 41, preparing for the next fiber pressing. This invention places the V-groove 53 on the lower surface of the upper pressure foot 5, enabling the V-groove 53 to position and press the optical fiber. The downward-facing opening of the V-groove 53 allows impurities at the angle of the V-groove 53 to fall off naturally, preventing residue and making the fiber positioning and pressing more stable.

[0045] Example 3 ( Figure 5-14The upper surface of the lower pressure foot 3 is provided with a lower square groove 31 that runs through the front and rear sides; the lower square groove 31 is rotatably connected to the right inner wall of a first rotating roller 32, a second rotating roller 33, and a third rotating roller 34, which are arranged in a triangular pattern; the first rotating roller 32 is positioned forward; the second rotating roller 33 is positioned rearward and is rotatably connected to the left inner wall of the lower square groove 31; the third rotating roller 34 is positioned lower and is rotatably connected to the left inner wall of the lower square groove 31; a transmission belt 35 is drivenly connected to the outer walls of the first rotating roller 32, the second rotating roller 33, and the third rotating roller 34; the inner side of the transmission belt 35... A support base 6 is provided; the support base 6 is fixedly connected to the lower pressure foot 3; the upper part of the transmission belt 35 protrudes from the upper end of the lower pressure foot 3; the left side of the lower pressure foot 3 is rotatably connected to the drive gear 7; the drive gear 7 is connected to the transmission belt 35 for transmission; the inner wall of the upper square groove 52 is vertically provided with an arc-shaped groove 54; the arc-shaped groove 54 extends downward and corresponds to the position of the drive gear 7; the inner wall of the arc-shaped groove 54 is uniformly provided with drive teeth 55; the drive teeth 55 can drive the drive gear 7 to rotate; the lower square groove 31 is provided with a scraping block 8 that contacts the outer wall of the transmission belt 35.

[0046] In this embodiment, a replacement groove 36 is provided through the bottom of the lower square groove 31; a replacement box 81 slides in the replacement groove 36; the bottom wall of the replacement box 81 is connected to a scraping block 8 by a replacement spring 82; the scraping block 8 slides up and down on the inner wall of the replacement box 81.

[0047] The upper pressure platform 4 moves around the hinge point between the windproof cover 2 and the body 1 along with the windproof cover 2. As the upper pressure platform 4 approaches the lower pressure foot 3, it moves in an arc. Therefore, the upper pressure platform 4 drives the upper pressure foot 5 to move along the arc towards the lower pressure foot 3. Only by setting the arc-shaped groove 54 on the upper pressure foot 5 to be smoothly engaged with the outside of the drive gear 7 can this be achieved. As the upper pressure foot 5 approaches the lower pressure foot 3, the upper end of the lower pressure foot 3 drives the optical fiber into the V-groove 53. The V-groove 53 on the lower surface of the upper pressure foot 5 guides and limits the optical fiber. The lower end of the arc-shaped groove 54 aligns with the drive gear 7, so the drive gear 7 moves relative to it and enters the arc-shaped groove 54. The multiple drive teeth 55 set on the inner wall of the arc-shaped groove 54 drive the meshing drive teeth. When wheel 7 rotates, the drive gear 7 rotates, which in turn drives the transmission belt 35 to rotate around the outer walls of the first roller 32, the second roller 33, and the third roller 34. The outer wall of the transmission belt 35 contacts the scraping block 8. Therefore, after the transmission belt 35 rotates, debris and other impurities on the outer wall of the transmission belt 35 are scraped away, thus ensuring the cleanliness of the outer wall of the transmission belt 35. This prevents residual impurities on the outer wall of the transmission belt 35 from affecting the placement of the optical fiber, making the placement of the optical fiber more stable, the limiting and pressing of the optical fiber more stable, and the splicing more stable. The debris scraped by the scraping block 8 from the outer wall of the transmission belt 35 falls into the replacement box 81 for collection. By pushing the replacement box 81 to slide along the replacement groove 36, the replacement box 81 can be removed, and the debris inside the replacement box 81 can be cleaned.

[0048] Example 4 ( Figure 5-14 The inner wall of the arc-shaped groove 54 is provided with a tooth groove 56 corresponding to the position of the driving tooth 55; the bottom of the tooth groove 56 is connected to the driving tooth 55 through a driving spring 57; the driving tooth 55 is provided with a first inclined surface 551 facing upward.

[0049] In this embodiment, the lower square groove 31 has a first rotating hole 37 corresponding to the first rotating roller 32 on its right inner wall; the inner wall of the first rotating hole 37 has a one-way groove 371; a one-way block 372 is slidably connected in the one-way groove 371; the one-way block 372 is connected to the bottom of the one-way groove 371 by a one-way spring 373; the one-way block 372 has a second inclined surface 374 tilted upwards; the first rotating roller 32 is rotatably connected in the first rotating hole 37; the outer wall of the first rotating roller 32 has block grooves 321 evenly arranged along the circumference for the one-way block 372 to be inserted.

[0050] As the upper presser foot 5 approaches the lower presser foot 3, the upper presser foot 5 will cause the lower end of the arc groove 54 to align with the drive gear 7. The drive gear 7 will move into the arc groove 54. Since the drive teeth 55 on the inner wall of the arc groove 54 are inclined upwards and have a first inclined surface 551, the drive teeth on the inner wall of the arc groove 54 will unidirectionally compress the drive gear 7 to rotate. During the rotation of the drive gear 7, the transmission belt 35 will drive the transmission belt 35 in one direction. During the unidirectional transmission of the transmission belt 35, the first roller 32 will rotate. The first roller 32 will drive the multiple block slots 321 at the end to move. The block slot 321 inserted into the one-way block 372 will use the slot opening of the block slot 321 to compress the second inclined surface 374 of the one-way block 372. The one-way block 372 will be compressed and will overcome the one-way spring 373 to retract into the one-way slot 371. The one-way block 372 does not restrict the rotation of the first roller 32; while the upper pressure foot 5 moves away from the lower pressure foot 3, the drive tooth 55 in the arc groove 54 will drive the first inclined surface 551 to contact the drive gear 7. The drive tooth 55 is compressed and retracts into the tooth groove 56, thus preventing the drive gear 7 from rotating. Furthermore, since the one-way block 372 is inserted into the block groove 321, the first roller 32 can only rotate in one direction in the first rotating hole 37. This makes the transmission belt 35 only able to perform unidirectional transmission, so that the outer wall of the transmission belt 35 used to support the optical fiber will be cleaned by the scraping block 8, improving the cleaning efficiency of the outer wall of the transmission belt 35. After the drive gear 7 moves out of the arc groove 54, the drive tooth 55 is pushed out of the tooth groove 56 and reset by the drive spring 57.

[0051] Example 5 ( Figure 5-14 The support base 6 has a first clearance groove 61 on its left inner wall; the lower square groove 31 has a long strip-shaped second clearance groove 38 on its left inner wall; the first clearance groove 61 and the second clearance groove 38 are connected; one end of the first clearance groove 61 extends to the end of the first roller 32; a first rotating wheel 71 is rotatably connected inside the first clearance groove 61; the first rotating wheel 71 passes through the lower pressure foot 3 and is fixedly connected to the drive gear 7; the first rotating wheel 71 is rotatably connected to the lower pressure foot 3; the other end of the first clearance groove 61 rotates. The first roller 71 is connected to the second roller 72; the outer wall of the first roller 71 and the second roller 72 is connected to the first belt 73; the second roller 74, which is fixed to the second roller 72, is rotatably connected in the second clearance groove 38; the outer wall of the second roller 33 is provided with an annular groove 331; the annular groove 331 and the outer wall of the third roller 74 are connected to the second belt 75; the diameter of the first roller 71 and the second roller 72 is smaller than the diameter of the second roller 33; the diameter of the third roller 74 is larger than the diameter of the second roller 33.

[0052] During the rotation of the drive gear 7, the first rotating wheel 71 will rotate, which in turn will drive the first belt 73. The first belt 73 will then drive the second rotating wheel 72. The outer walls of both the first and second rotating wheels 71 and 72 are provided with first anti-slip teeth (not shown in the figure). The inner wall of the first belt 73 is provided with a first anti-slip groove (not shown in the figure) along the transmission direction. The first anti-slip teeth can sequentially engage with the first anti-slip groove to achieve anti-slip. During the rotation of the second rotating wheel 72, the third rotating wheel 74 will rotate, which in turn will drive the second belt 75. The second belt 75 will then drive the second rotating roller 33. The annular groove 331 is provided at the contact point with the inner wall of the second belt 75 and on the outer wall of the second rotating wheel 72. The second belt 75 is provided with a second anti-slip tooth (not shown in the figure) and a second anti-slip groove (not shown in the figure) on its inner wall. The second anti-slip tooth can be inserted into the second anti-slip groove in sequence to achieve anti-slip. During the rotation of the second roller 33, the transmission belt 35 will be driven by the first roller 32, the second roller 33 and the third roller 34 are provided with a third anti-slip tooth on their outer walls. The transmission belt 35 is provided with a third anti-slip groove on its inner wall. The third anti-slip tooth can be inserted into the third anti-slip groove in sequence to achieve anti-slip. Since the diameter of the third roller 74 is much larger than the diameter of the second roller 33, the second roller 33 rotates much more than one revolution when the drive gear 7 rotates one revolution. This makes the transmission travel of the transmission belt 35 longer and the upper outer wall of the transmission belt 35 is replaced, improving the cleanliness of the outer wall of the transmission belt 35 in contact with the optical fiber.

[0053] Example 6 ( Figure 5-14 The inner wall of the arc-shaped groove 54 where the driving tooth 55 is provided has a notch 58; the notch 58 is located near the upper pressure table 4.

[0054] With the notch 58 in place, during the final pressing of the optical fiber by the V-groove 53 of the upper pressure foot 5, the drive gear 7 enters the range of the notch 58, thus preventing the drive gear 7 from meshing with the drive tooth 55. This stops the transmission belt 35 from moving, ensuring that the transmission belt 35 does not move during the final pressing of the optical fiber, making the pressing of the optical fiber more stable. After the upper pressure foot 5 moves upward, the drive gear 7 will move out of the notch 58.

[0055] Example 7 ( Figure 5-14 The replacement box 81 is internally embedded with a first magnet 83; the inner wall of the replacement groove 36 is internally embedded with a second magnet 84 near the first magnet 83; the first magnet 83 and the second magnet 84 are magnetically attracted to each other, and under the magnetic attraction, the replacement box 81 is placed more smoothly and stably in the replacement groove 36.

[0056] Example 8 ( Figure 5-14The outer wall of the transmission belt 35 is uniformly provided with protrusions 351 along the transmission direction; the single transmission stroke of the transmission belt 35 is an integer multiple of the distance between two adjacent protrusions 351. After the optical fiber is placed on the outer wall of the transmission belt 35, the transmission belt 35 is forced to drive as the upper pressure foot 5 moves down. During the transmission process, the transmission belt 35 drives the protrusions 351 to drive. During the contact between the protrusions 351 and the optical fiber, the protrusions 351 move the optical fiber, so that the optical fiber completes a slight vibration before final pressing, so that the surface deposits of the optical fiber are shaken off before the closest point to the optical fiber is pressed, further improving the optical fiber splicing effect. It should be noted that each time the transmission belt 35 stops driving, the protrusions 351 on the transmission belt 35 will be offset from the position where the optical fiber is pressed, so as to avoid the protrusions 351 affecting the pressing of the optical fiber.
