[0002] An optical fiber fusion splicer is a high-tech instrument that combines optics, electronics, and precision machinery. Therefore, it is also known as an optical cable fusion splicer. Its working principle is to melt the cross-sections of two optical fibers through a high-voltage arc, and at the same time, use a high-precision motion mechanism to gently push forward, so that the two optical fibers are fused into one, thereby realizing the coupling of the optical fiber mode field and ensuring the effective transmission of signals. It has a wide range of applications in the field of optical fiber communication. Optical fiber fusion splicers are mainly used in the construction, maintenance, and emergency repair of optical cable lines by telecom operators, engineering companies, and public institutions, as well as in the production and testing of optical fiber devices and the research and teaching of research institutes. In addition, optical fiber fusion splicers are also used in fields such as medical and aerospace for optical cable laying and optical fiber repair, etc. It mainly includes single-fiber (core) fusion splicers and multi-fiber (core) fusion splicers. Single-fiber fusion splicers are popular because of their simplicity and ease of use, while multi-fiber fusion splicers are more suitable for the connection work of ribbon optical cables. According to the type of optical fiber, optical fiber fusion splicers can also be divided into multi-mode fusion splicers, single-mode fusion splicers, and multi-mode / single-mode dual-purpose fusion splicers. Multi-mode fusion splicers are usually not suitable for the fusion splicing of single-mode optical fibers, and although single-mode fusion splicers can be compatible with multi-mode optical fibers, their economy is poor. Therefore, multi-mode / single-mode dual-purpose fusion splicers are favored because of their flexibility.

[0003] The prior document with the publication number CN220671683U discloses an optical fiber fusion splicer, which relates to the technical field of optical fiber processing.

In use, it realizes the effect of facilitating the rapid fusion splicing of optical fibers with a cladding of 600 microns or more, effectively expanding the applicable range of the existing optical fiber fusion splicer, better meeting the market demand, and having good practicability.

[0004] The V-shaped groove for supporting the optical fiber in the above-mentioned optical fiber fusion splicer has certain limitations. Its fixed groove width cannot automatically adapt to the different diameters of the optical fibers mentioned above. And due to its own material problems, the V-shaped groove is easily scratched by vibration interference to the bare fiber.

[0026] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0027] The present invention provides a technical solution: an automatic core alignment structure of an optical fiber fusion splicer, such as Figures 1-6 As shown, it includes a fusion splicer body 1 and a core support assembly 5. A mounting frame 2 is installed above the fusion splicer body 1. An electrode rod 3 and two fusion splicing clamps 4 are arranged inside the mounting frame 2. The electrode rod 3 is used to melt and splice the end faces of the optical fibers. The fusion splicing clamps 4 are used to fix the optical fibers to ensure the flatness and alignment accuracy of the end faces of the optical fibers, thereby ensuring the quality and stability of the fusion splicing and preventing movement or deviation during the fusion splicing process. A fiber alignment driving mechanism is installed inside the mounting frame 2. A windproof cover 6 is installed above the fusion splicer body 1 to prevent The interior of the wind cover 6 is equipped with dual cameras and dual-angle lighting LEDs. The dual cameras are arranged at 90 degrees to each other, so that the operator can observe the optical fiber status from different angles to ensure the quality of welding. The dual-angle lighting LED is convenient for users to observe in dim environments and meet outdoor work needs. A heating groove 7 for shrinking the heat shrinkable tube is installed above the welding machine body 1, so that the heat shrinkable tube is tightly wrapped on the welding point, thereby enhancing the stability and waterproofness of the optical fiber joint. An intelligent operation screen 8 is installed on the front of the welding machine body 1.

[0028] like Figures 1-6As shown, the core support assembly 5 is disposed inside the mounting frame 2. The core support assembly 5 includes two core alignment seats 51 disposed above the fiber alignment drive mechanism. When the fiber ends are aligned, the fiber alignment drive mechanism drives the core alignment seats 51 to accurately align the fiber ends. The electrode rod 3 is installed between the two core alignment seats 51. In the automatic welding mode, the electrode rod 3 will melt the cross-section of the optical fiber through a high-voltage arc, enabling the two optical fibers to smoothly fuse into one. Two symmetrically arranged air storage cavities 52 are opened inside each of the two core alignment seats 51. On both sides of the inner walls of the two air storage cavities 52, air charging and discharging pipe cavities 53 are opened. A one-way valve can be provided inside the air charging and discharging pipe cavities 53 to prevent air from automatically discharging from the air charging and discharging pipe cavities 53 later. When the air inside the air storage cavity 52 flows, it will be discharged through the two air charging and discharging pipe cavities 53. The core support assembly 5 further includes two alignment members.

[0029] As Figures 1-6 shown, the two alignment members are respectively disposed above the two core alignment seats 51. The alignment member includes two rigid vertical plates 54 disposed above the core alignment seat 51. Arc-shaped wrapping bags 55 are fixed outside the two rigid vertical plates 54. The arc-shaped surfaces of the two arc-shaped wrapping bags 55 are arranged opposite to each other. Two air charging and discharging pipes 56 are installed on one side of each of the two arc-shaped wrapping bags 55. One end of each air charging and discharging pipe 56 corresponds to an air storage cavity 52, and one end of each air charging and discharging pipe 56 is fixedly connected to one end of the air storage cavity 52 corresponding to its position.

[0030] As Figures 1-6 shown, the core support assembly 5 further includes two charging and discharging members. The two charging and discharging members are both connected to the two alignment members through the air charging and discharging pipes 56. The charging and discharging members are used to fill the gas inside the air storage cavity 52 into the arc-shaped wrapping bags 55 in the alignment members. The charging and discharging member includes a sealing plug plate 57 that slides inside the two air storage cavities 52 respectively, a positive reset magnetic sheet 58 fixed to the top of the inner walls of the two air storage cavities 52 respectively, and two pushing arms 511 fixed inside the windproof cover 6. Negative reset magnetic sheets 59 are fixed above the two sealing plug plates 57. The suction force of the positive reset magnetic sheet 58 and the negative reset magnetic sheet 59 provides an upward reset force for the sealing plug plate 57. Springs can also be added above or below the sealing plug plate 57. The springs cooperate with the positive reset magnetic sheet 58 and the negative reset magnetic sheet 59 to assist the sealing plug plate 57 to reset upward. Assistive arm rods 510 are fixed above the two sealing plug plates 57. One end of each of the two assistive arm rods 510 extends above the core alignment seat 51. The position of the pushing arm 511 inside the windproof cover 6 corresponds to the position of the assistive arm rod 510. When the windproof cover 6 covers the core support assembly 5, the electrode rod 3, and the welding fixture 4 inside the mounting frame 2, the pushing arm 511 will first contact the assistive arm rod 510, causing the assistive arm rod 510 to push the sealing plug plate 57 downward.

[0031] As Figures 1-6As shown in the figure, anti-falling components are provided on the outside of both of the two arc-shaped wrapping sacs 55. The anti-falling components are used to prevent the arc-shaped wrapping sacs 55 from falling as a whole due to gravity. During the deflation process of the arc-shaped wrapping sacs 55, the anti-falling components will cause them to be close to the rigid vertical plate 54, preventing the arc-shaped wrapping sacs 55 from falling and then being unable to accurately wrap around the optical fiber during re-inflation. The anti-falling components include a plurality of pulling ropes 512 respectively fixed at both ends of the arc-shaped wrapping sacs 55. One end of each of the plurality of pulling ropes 512 penetrates into the inside of the rigid vertical plate 54, and a pulling gravity weight 513 is fixed at one end of each of the plurality of pulling ropes 512. In order to prevent the pulling gravity weights 513 from obstructing each other when falling, the positions where the pulling ropes 512 at the same end penetrate through the rigid vertical plate 54 are staggered and not on the same vertical line.

[0032] As Figures 1-6 shown, two receiving inner grooves 514 are provided above the core seat 51, and are respectively located at both ends of the arc-shaped wrapping sac 55. The core support assembly 5 further includes two preliminary positioning components, which are respectively arranged above the two core seats 51. The preliminary positioning components are used to preliminarily position and support the optical fiber. The preliminary positioning components include inclined surface support plates 515 respectively sliding inside the two receiving inner grooves 514 and two displacement push plates 516 fixed inside the windproof cover 6. The two inclined surface support plates 515 are arranged in a staggered manner, and the inclined surfaces face each other, forming a staggered V-shaped support seat. Springs 517 are provided below both of the two inclined surface support plates 515. When the springs 517 are in their original lengths, the two inclined surface support plates 515 are outside the receiving inner grooves 514.

[0033] As Figures 1-6 shown, a traction groove 518 is provided inside the inclined surface support plate 515, and an anti-displacement component is arranged inside the traction groove 518. The anti-displacement component is used to wipe off the dust on the surface of the inclined surface support plate 515. Limiting grooves 519 are respectively provided on both sides of the inner walls of the two receiving inner grooves 514. The anti-displacement component includes a sliding head 520 sliding inside the limiting groove 519. One end of the sliding head 520 is fixed with a traction piece 521, and the traction piece 521 slides inside the traction groove 518. When the inclined surface support plate 515 is pressed and moves up and down along the receiving inner groove 514, the traction piece 521 will drive the sliding head 520 to slide in the limiting groove 519. A wiping piece 522 is fixed above the traction piece 521, and the wiping piece 522 is arranged on the upper surface of the inclined surface support plate 515. When the inclined surface support seat 515 moves down, the wiping piece 522 wipes from the lower position to the upper position. On the contrary, when the inclined surface support seat 515 moves up, the wiping piece 522 wipes from the upper position to the lower position. Every time an optical fiber is spliced, the wiping piece 522 can clean the inclined surface support plate 515 twice before and after each optical fiber splicing, effectively avoiding the phenomenon that the optical fiber is tilted or lifted due to the presence of dust.

[0034] In use, prepare the optical fiber, strip off the outer sheath of the optical fiber to expose the optical fiber core, sleeved the heat shrinkable tube on one of the optical fibers, then use an optical fiber cutter to cut the optical fiber to make the end face of the optical fiber smooth and neat, clean the end face of the optical fiber with alcohol or a professional cleaning tissue to remove dirt and grease on the optical fiber, place the two optical fibers into the fusion fixture 4 on the fuselage 1 of the fusion splicer respectively, and make the optical fiber fall on the inclined plane support plate 515 to initially limit the position of the optical fiber, align the two optical fiber end faces, then close the windproof cover 6. When the windproof cover 6 is closed, the pushing arm 511 will first contact the assisting arm rod 510 and press down the assisting arm rod 510, thereby pressing down the sealing plug plate 57. The pressing down of the sealing plug plate 57 will push the air inside the air storage cavity 52 through the charging and discharging pipe cavity 53 into the charging and discharging pipe 56, and along the charging and discharging pipe 56 into the arc-shaped wrapping bag 55. After the arc-shaped wrapping bag 55 is inflated, it will wrap the optical fiber. And under the continuous pressing down of the windproof cover 6, the displacement push plate 516 will push the inclined plane support plate 515 when the arc-shaped wrapping bag 55 continues to be inflated, and push the inclined plane support plate 515 into the storage inner groove 514 to prevent the inclined plane support plate 515 from contacting the optical fiber. The arc-shaped wrapping bag 55 wraps the optical fiber, can support different diameters of optical fibers, and the arc-shaped wrapping bag 55 evenly wraps the optical fiber, with a soft pressure distribution and can also absorb vibration, having good protection and effectively avoiding damage to the bare optical fiber. If dust adheres to the surface of the arc-shaped wrapping bag 55, through the flexible adaptive compensation of the arc-shaped wrapping bag 55, the tolerance to dust is higher, reducing the phenomenon that the optical fiber is displaced due to the presence of dust and causing misalignment of the cores. Then, the core alignment driving mechanism can be started to drive the core alignment seat 51 to move, thereby automatically aligning the end faces of the optical fibers to ensure good butt joint of the end faces of the optical fibers. Start the fusion function, the electrode rod 3 will heat the end faces of the optical fibers to melt and fuse them together. After the fusion is completed, move the heat shrinkable tube to the optical fiber fusion position to wrap the fusion position, and place the heat shrinkable tube in the heating groove 7 for heating to tightly wrap the heat shrinkable tube on the fusion point, thereby enhancing the stability and waterproofness of the optical fiber joint.

[0035] When the arc-shaped wrapping bag 55 is inflated, it will pull the pulling rope 512 connected to it to slide, and the pulling rope 512 will drive the pulling gravity weight 513 to slide until it is close to the rigid vertical plate 54. After the windproof cover 6 is opened later, under the attracting force of the positive reset magnetic sheet 58 and the negative reset magnetic sheet 59, and with the thrust provided by the assembled spring member, the sealing plug plate 57 moves up and resets, thereby pumping the air in the arc-shaped wrapping bag 55 back into the air storage cavity 52. The arc-shaped wrapping bag 55 will deflate, and under the pulling of the pulling gravity weight 513 and the pulling rope 512, the arc-shaped wrapping bag 55 is pulled to a position close to the rigid vertical plate 54 to prevent the entire arc-shaped wrapping bag 55 from dropping, affecting the inability of the arc-shaped wrapping bag 55 to wrap the optical fiber during subsequent inflation.

[0036] When the inclined surface support plate 515 is pressed down, it will drive the traction piece 521 through the traction groove 518 to drive the sliding head 520 to move. The sliding head 520 will be limited by the limiting groove 519, so that the wiping piece 522 slides on the upper surface of the inclined surface support plate 515 to wipe the dust on the inclined surface support plate 515. After the windproof cover 6 is opened later and the pressure of the displacement push plate 516 is lost, under the thrust of the spring 517, the inclined surface support plate 515 will move upward. At this time, the traction piece 521 will drive the sliding head 520 to slide in the limiting groove 519 to the initial position under the limitation of the traction groove 518, and the sliding head 520 will drive the wiping piece 522 to slide from above the inclined surface support plate 515 to below the inclined surface support plate 515 and hide at the staggered corner of the two inclined surface support plates 515, so as not to affect the stability of the optical fiber placed between the two inclined surface support plates 515. Moreover, the wiping piece 522 can clean the inclined surface support plate 515 twice before and after each optical fiber fusion, which can effectively avoid the phenomenon that the optical fiber is tilted or lifted due to the presence of dust.

[0037] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all of them will fall within the protection scope of the present invention.
