[0002] Optical fiber is a thin, long fiber made of glass or plastic that transmits light signals through total internal reflection, enabling high-speed, long-distance information transmission. Fiber optic welding is a technique that uses a high-intensity light beam to melt and connect the ends of optical fibers. The high-intensity beam is focused on the ends of the fibers, melting them and rapidly joining them together. This process requires no physical contact and produces no slag, ensuring the precision and cleanliness of the connection. Fiber optic welding has wide applications in high-speed optical communication and optoelectronic equipment manufacturing. In optical communication networks, it can connect optical fibers of different materials, diameters, and types to build complete network systems, reduce optical signal loss, and improve transmission quality.

[0003] Currently, traditional fiber optic welding equipment requires manual handling of the fiber optic assembly during welding, as well as manual movement of the assembly to adjust its welding position. This not only increases operational complexity and reduces welding efficiency, but also easily leads to unstable welding quality due to human factors. Utility Model Content

[0004] The purpose of this invention is to provide an optical fiber welding device to solve the problem mentioned in the background art, which requires manual hand-held welding of optical fiber assemblies and manual movement of the optical fiber assemblies to adjust their welding position.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: an optical fiber welding device, including a base 1 and a top cover 2. The top cover 2 is movably snapped onto the top of the base 1. A support seat 3 is fixedly installed in the center of the base 1. Welding heads 4 are fixedly installed on the front and rear sides of the support seat 3 and are horizontally centered outside the base 1. Pushing mechanisms 5 are fixedly installed inside the base 1 and are symmetrically arranged on the left and right sides of the support seat 3. Adsorption mechanisms 6 are fixedly installed at the four corners of the outer side of the base 1. The pushing mechanism 5 includes a connecting seat 51 fixedly installed inside the base 1. An electric guide rail 52 is fixedly installed on the front side of the connecting seat 51. A slider 53 is movably installed on the outside of the electric guide rail 52. A clamping block 54 is fixedly installed on the outside of the slider 53. A connecting plate 55 is fixedly installed on the front side of the clamping block 54. A pull rod 56 is movably snapped into the inside of the connecting plate 55. A clamping block 57 is fixedly installed on the rear side of the pull rod 56 and is connected to the clamping block 54. A suction mechanism 6 is movably installed on the outside of the pull rod 56. Spring 58 between clamping block 57 and connecting plate 55, and clamping slots 59 inside clamping block 54 and clamping block 57, can drive slider 53 to slide via electric guide rail 52. This not only facilitates precise adjustment of the fiber position but also greatly improves work efficiency. Under the clamping action of clamping block 54 and clamping block 57, the fiber can be kept stable and not easily slipped, further ensuring welding quality. The design of clamping slot 59 fits the shape of the fiber, and the fiber is subjected to uniform force during clamping, avoiding damage to the fiber. By pulling rod 56, clamping block 57 slides and spring 58 is squeezed to separate clamping block 57 from clamping block 54. The fiber is placed in clamping slot 59. After releasing pull rod 56, spring 58 pushes clamping block 57 to clamp the fiber for fixation. Slider 53 can move along electric guide rail 52 to push the fiber to adjust its position, reducing the complexity of operation, improving welding efficiency, and ensuring stable welding quality.

[0023] The connecting plate 55 is arranged in an "L" shape, and the clamping groove 59 and clamping block 54 are set at the same horizontal height to match each other. The optical fiber can remain stable during the clamping process. The "L" shape of the connecting plate 55 not only enhances the stability of the structure, but also provides convenience for operation, making the placement and adjustment of the optical fiber simpler and more intuitive. The setting of the clamping groove 59 and clamping block 54 at the same horizontal height ensures that the optical fiber is subjected to uniform force during the clamping process, further improving the stability and quality of welding.

[0024] The bottom of the top cover 2 is fixedly installed with a pressing mechanism 7 arranged symmetrically on the left and right. The pressing mechanism 7 includes a sleeve 71 and a spring 72 movably sleeved on the outside of the sleeve 71. The bottom of the sleeve 71 is fixedly installed with a pressure plate 73 located directly above the support base 3. The setting of the spring 72 enables the pressure plate 73 to maintain a certain pressure to press the optical fiber when it is not subjected to external force, thus ensuring the stability of the optical fiber during the welding process and avoiding positional displacement during welding.

[0025] The top of the support base 3 is fixedly equipped with a preheating mechanism 9 arranged symmetrically at the front and back. The preheating mechanism 9 adopts resistance heating or induction heating, which can preheat the optical fiber before welding, so that the optical fiber reaches a suitable welding temperature, thereby improving welding efficiency and welding quality.

[0026] Please see Figure 1 and Figure 5 The adsorption mechanism 6 includes a mounting block 61 fixedly connected to the side corner of the base 1. A connecting pipe 62 is fixedly installed inside the mounting block 61. A ball valve 64 is movably engaged inside the connecting pipe 62. A through hole 65 is opened inside the ball valve 64. A rotating rod 63 located outside the connecting pipe 62 is fixedly connected to the outside of the ball valve 64. A rotating wheel 66 is fixedly connected to the outside of the rotating rod 63. A suction cup 67 is fixedly connected to the bottom of the connecting pipe 62. The rotating wheel 66 can easily control the opening and closing of the ball valve 64. By rotating the rotating wheel 66, the rotating rod 63 and the ball valve 64 are rotated, thereby changing the communication state between the through hole 65 and the inside of the connecting pipe 62, realizing the adsorption and release function of the suction cup 67. The operation is simple and improves the stability and accuracy of optical fiber in the welding process.

[0027] Please see Figure 2 and Figure 4 Both sides of the base 1 are provided with access openings 11 corresponding to the positions of the support base 3, and the top of the access opening 11 is provided with a boss 12.

[0028] The bottom of the top cover 2 is provided with a groove 21 that matches the boss 12, and the top of the top cover 2 is fixedly installed with a centrally located observation window 8.

[0029] The boss 12 and the groove 21 can engage with each other, which facilitates the placement and alignment of the top cover 2 on the base 1. The opening 11 facilitates the insertion of optical fibers from both sides into the base 1 for welding operations.

[0030] The setting of observation window 8 facilitates real-time observation of the fiber optic welding process.

[0031] Working principle: The device is placed on the worktable via base 1. At this time, the connecting pipe 62 and the through hole 65 are in communication, allowing air to flow through the connecting pipe 62 and the suction cup 67, thus preventing the suction cup 67 from having suction force. Rotating the rotating wheel 66 drives the rotating rod 63, which in turn drives the ball valve 64 to rotate inside the connecting pipe 62. By rotating the ball valve 64 90 degrees, the ball valve 64 and the connecting pipe 62 are sealed, preventing internal air flow. This allows the suction cup 67 to have suction force, adsorbing and fixing the device onto the smooth surface, ensuring placement stability.

[0032] In use, pulling the lever 56 forward causes the clamping block 57 to slide forward, squeezing the spring 58 between the connecting plate 55 and the clamping block 57, thus separating the clamping block 57 from the clamping block 54. The fiber to be welded is then placed in the clamping slot 59, and the lever 56 is released. The spring 58 pushes the clamping block 57 backward to clamp and fix the fiber. The other fiber is clamped and fixed in the same way. Then, the slider 53 is driven by external control to slide along the electric guide rail 52, thus moving the fiber. When the fiber ends are on the support base 3, the preheating mechanism 9 can be opened to preheat the fiber. Once the fiber ends reach the welding head 4, the top cover 2 is placed on top of the base 1. The pressure plate 73, under the elastic force of the spring 72 and the sleeve 71, presses the fiber, preventing positional displacement during welding. Then, the welding head 4 is opened to weld the fiber connection. The welding process can be easily observed in real time through the observation window 8.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
