Description

Technical Field

[0001] The utility model relates to a vertically baked optical fiber curing tool, belonging to the technical field of optical fiber curing. Background Art

[0002] The invention of the laser is a major achievement of science and technology in the 20th century and is one of the essential core components in modern laser processing systems. Due to the outstanding characteristics of lasers, such as good monochromaticity, good directionality, high power and high brightness, they were quickly used in industry, agriculture, precision measurement and detection, communication and information processing, medical treatment, military and other fields, and have caused revolutionary breakthroughs in many fields. In addition to being used in military applications such as communication, night vision, early warning, and ranging, a variety of laser weapons and laser-guided weapons have also been put into practical use.

[0003] Due to the advantages of optical fiber transmission such as low loss, light weight, strong anti-interference ability, reliable performance and low cost, optical fiber jumpers are often used to transmit lasers during the production and application of lasers. Therefore, high-quality and high-efficiency processing of optical fiber jumpers is part of laser processing.

[0004] The fiber optic patch cord includes a fiber optic connector, an optical fiber and a protective tube. The optical fiber is sheathed in the protective tube. The fiber optic connector includes a ferrule and a nut. The ferrule is fixedly connected to an aluminum tube, and the ferrule is arranged in the nut. Different types of fiber optic connectors are installed at both ends of the optical fiber. The optical fiber is inserted into the ferrule of the fiber optic connector, and the ferrule is connected to the optical fiber by curing glue.

[0005] The commonly used heating method is to place the optical fiber and optical fiber connector horizontally on the heating table of the optical fiber curing furnace. Due to the fluidity of the glue, the glue will flow back during the curing process. The glue backflow will cause insufficient glue inside the optical fiber connector, and the fixing effect on the optical fiber will not achieve the expected effect. The optical fiber is easily damaged and burned, and the glue will stick the optical fiber and the protective tube together, which will affect the effect of laser transmission.

[0006] Existing optical fiber curing tooling, such as Chinese patent document CN114637085B, discloses an adjustable tilting optical fiber curing tooling. The use of this tooling will cause uneven heating of the optical fiber, a long heating time, and cannot completely prevent the backflow of glue when the tilt angle is small. When the tilt angle is too large, the optical fiber connector will not be completely fixed, and the optical fiber connector will fall off during the curing process, reducing the qualified rate of optical fiber jumpers. Moreover, in the existing optical fiber production process, in order to improve the efficiency of optical fiber curing, multiple optical fibers and optical fiber connectors are generally initially fixed at one time and then cured in batches. However, during the curing process of the optical fiber, due to the large number of optical fibers in a group, a fixing plate is usually used to directly press the optical fiber. This method will cause the optical fiber to be unevenly stressed before and after the curing process, causing the optical fiber to detach from the inside of the optical fiber connector. The optical fiber protective tube will also be subjected to a large extrusion force, and the optical fiber may be damaged. Summary of the invention

[0007] In view of the deficiencies in the prior art, the utility model provides a vertically baked optical fiber curing tooling, which fixes the optical fiber connector and the optical fiber front and back at the same time, and adopts vertical baking to avoid glue backflow and optical fiber detachment and damage, thereby improving product quality. Moreover, during the baking process, the optical fiber is heated evenly, the heating time is shortened, and the production efficiency is improved.

[0008] The technical solution of the utility model is as follows:

[0009] A vertically baked optical fiber curing tool comprises a base, a bottom plate, a rotating seat A, a rotating seat B, a limit block, a lower fixed plate, an upper fixed plate, a limit plate, a fixed seat A and a fixed seat B, wherein:

[0010] A bottom plate is vertically arranged on the base, a rotating seat A and a fixed seat A are symmetrically arranged at the lower part of the bottom plate, a lower fixed plate is arranged between the rotating seat A and the fixed seat A, a plurality of limit grooves are arranged on the lower fixed plate, a plurality of limit blocks are evenly arranged on the bottom plate under the lower fixed plate, a rotating seat B and a fixed seat B are symmetrically arranged on the upper part of the bottom plate, an upper fixed plate is arranged between the rotating seat B and the fixed seat B, a limit plate is fitted on the inner side of the upper fixed plate, and a plurality of through holes are arranged between the upper fixed plate and the limit plate.

[0012] The fixing seat A is a C-shaped seat, and the other end of the lower fixing plate is fixed inside the fixing seat A through a rotating shaft.

[0013] According to the preferred embodiment of the utility model, the rotating seat B includes a seat B, a rotating plate B and a fixed shaft B. The seat B is a rectangular seat. Two seat Bs are symmetrically fixed to one side of the limiting plate. An upper fixed plate is arranged between the two seat Bs. A slot B is arranged on one side of the limiting plate. The rotating plate B is fixed to one side of the bottom plate. The rotating plate B is a C-shaped plate. A block B is arranged on the inner side of the rotating plate B. One end of the upper fixed plate is arranged in the rotating plate B through the fixed shaft B. When installing, the block B and the slot B limit the installation position of the lower fixed plate and the limiting plate.

[0014] The fixing seat B is a C-shaped seat, and the other end of the upper fixing plate is fixed inside the fixing seat B through a rotating shaft.

[0015] Preferably, according to the utility model, the base includes a support plate and a fixed block, two fixed blocks are arranged side by side in the middle of the support plate, the connection between the fixed block and the support plate is arranged as a cross-shaped slot, and the bottom of the base plate is slidably connected to the base through a cross-shaped block.

[0018] When in use, open rotating seat A and rotating seat B, rotate the upper fixing plate and the lower fixing plate, place multiple fiber optic connectors on the upper side of the limit blocks, and place the nuts of the fiber optic connectors on the limit blocks. During the vertical baking process, the fiber optic connectors can be prevented from sliding down, and the fiber optic connectors can be prevented from falling off, resulting in poor jumper production. Then the lower fixing plate is snapped onto the rotating seat A to fix the fiber optic connector. The ferrule is just located in the gap between the limit blocks.

The upper part of the protective tube is placed in the through hole position of the limit plate, and the upper fixing plate is snapped onto the rotating seat B to complete the fixation of the fiber optic jumper. Then the tooling is placed in the baking oven. The optical jumper is placed vertically during the baking and fixing process. Due to the increase in fluidity of the glue in the initial stage of heating, the glue will flow downward when placed vertically, which can make the glue fill the fiber optic connector more fully and prevent the glue from flowing out of the fiber optic connector and flowing back into the protective tube.

[0019] The beneficial effects of the utility model are:

[0020] 1. During the baking process of the utility model, the optical fiber and the optical fiber connector are placed vertically, which can prevent the glue from flowing back into the protective tube and the phenomenon of glue reflux, thereby improving the quality of the product, reducing the maintenance rate and reducing the cost.

[0021] Moreover, the optical fiber connector is fixed by a limit block to avoid the optical fiber being detached and damaged at the optical fiber connector, thereby improving the product qualification rate.

[0022] 2. The optical fiber and optical fiber connector of the utility model are placed vertically in a baking oven for curing. Since the temperature inside the baking oven is evenly distributed, the optical fiber curing tooling is placed inside so that the overall heating of the optical fiber jumper is more even, the heating time is shortened, and the production efficiency is improved.
