[0028] The following will be described in combination with Figures 1-4 The drying and assembling device of the prefabricated rod of the present application is described.
[0029] As Figure 1 and Figure 2 shown, in the embodiment of the present application, the drying and assembling device of the prefabricated rod comprises a plurality of pipe bodies 1, a connecting piece 2 and a gas source assembly. The plurality of pipe bodies 1 are arranged in the connecting piece 2, the arrangement form of the plurality of pipe bodies 1 is the same as the arrangement form of the plurality of holes in the prefabricated rod 101, the plurality of pipe bodies 1 are connected with the gas source assembly, when drying the holes, the gas source assembly is used to introduce gas into the pipe body 1, when assembling the core rod and the hole, the gas source assembly is used to extract the gas in the pipe body 1, so that the pipe body 1 adsorbs the core rod.
[0030] A plurality of holes are drilled in the prefabricated rod 101, and the prefabricated rod 101 is connected with the tail pipe 102. The arrangement form of the plurality of pipe bodies 1 is the same as the arrangement form of the plurality of holes in the prefabricated rod 101. When drying the holes in the prefabricated rod 101, each pipe body 1 extends into a hole, and the gas source assembly introduces gas into the pipe body 1 to dry the hole. When it is needed to assemble the core rod into the hole of the prefabricated rod 101, the gas source assembly extracts the gas in the pipe body 1, so that the pipe body 1 adsorbs the core rod by using negative pressure, and when the pipe body 1 places the core rod in the hole, the gas source assembly stops working, and the pipe body 1 separates from the core rod.
[0031] In the embodiment, the arrangement form of the plurality of pipe bodies 1 is the same as the arrangement form of the plurality of holes in the prefabricated rod 101, so that after the pipe body 1 extends into the prefabricated rod 101, each pipe body 1 can be opposite to a hole, so that the plurality of holes can be dried at the same time; correspondingly, when the core rod is assembled, each pipe body 1 adsorbs a core rod, and after the plurality of pipe bodies 1 extend into the prefabricated rod 101 at the same time, the plurality of core rods can be assembled with the holes of the prefabricated rod 101 at the same time, so that the drying and assembling efficiency of the prefabricated rod is greatly improved.
[0032] The drying and assembling device of the prefabricated rod provided by the embodiment of the utility model can dry multiple holes in the prefabricated rod at the same time, and can assemble multiple mandrels and multiple holes in the prefabricated rod at the same time, thereby improving the drying and assembling efficiency of the prefabricated rod.
[0033] As Figure 2 shown in the embodiment of the utility model, each pipe body 1 comprises: a first pipe body 11 and a second pipe body 12, the first pipe body 11 is threadedly connected with the second pipe body 12, and the second pipe body 12 is arranged in the connecting piece 2.
[0034] Specifically, the first pipe body 11 is threadedly connected with the second pipe body 12, and by screwing in or out, the length of the second pipe body 12 can be adjusted, and then the length of the whole pipe body 1 can be adjusted, so that when the prefabricated rod 101 is connected with the tail pipe 102 of different lengths, the length of the pipe body 1 is always greater than the length after the prefabricated rod 101 is connected with the tail pipe 102, so that the pipe body 1 can extend into the hole in the prefabricated rod 101, so as to ensure the drying effect; at the same time, it is ensured that the pipe body 1 can send the mandrel into the hole.
[0035] Further, in the embodiment of the utility model, the outer diameter of the first pipe body 11 is smaller than the inner diameter of the hole, so that the first pipe body 11 can extend into the hole to dry the hole, thereby ensuring the drying effect.
[0036] Further, when assembling the mandrel and the hole in the prefabricated rod 101, the first pipe body 11 needs to adsorb the mandrel first, therefore, the inner diameter of the first pipe body 11 should be matched with the outer diameter of the mandrel, and at the same time, the inner diameter of the second pipe body 12 is smaller than the inner diameter of the first pipe body 11, so as to facilitate the first pipe body 11 to adsorb the mandrel.
[0037] As Figure 2 shown in the embodiment of the utility model, the connecting piece 2 comprises: a barrel 21 and a bottom plate 22, the bottom plate 22 is arranged at one end of the barrel 21, and the pipe body 1 penetrates the bottom plate 22, when the pipe body 1 extends into the prefabricated rod 101, the barrel 21 can be sleeved with the tail pipe 102.
[0038] Specifically, each pipe body 1 is arranged in the bottom plate 22 of the connecting piece 2, so as to fix each pipe body 1. When drying the hole in the prefabricated rod 101, multiple pipe bodies 1 extend into the hole of the prefabricated rod 101, and the barrel 21 of the connecting piece 2 is just sleeved with the outer wall of the tail pipe 102, so that a closed space is formed in the prefabricated rod 101, which ensures that the prefabricated rod 101 is isolated from the outside world during drying and assembling, and is not polluted, not only improving the drying effect of the hole in the prefabricated rod 101, but also improving the quality of the polarization maintaining optical fiber.
[0039] As Figure 3 and Figure 4As shown, according to the arrangement of the plurality of holes in the preform rod 101, the arrangement of the plurality of tube bodies 1 is also various, such as Figure 3 As shown in the second embodiment, four tube bodies 1 are arranged on the connecting piece 2; or such as Figure 4 As shown in the third embodiment, two tube bodies 1 are arranged on the connecting piece 2. Regardless of the arrangement of the plurality of tube bodies 1, the bottom plate 22 of the connecting piece 2 is provided with a plurality of exhaust holes 3 to exhaust the dried gas.
[0040] Optionally, in the embodiment of the present application, the diameter of the exhaust hole 3 can be 2mm.
[0041] In the prior art, when the core rod is assembled in the hole of the preform rod 101, the assembly process is relatively random, which is easy to cause pollution or scratch on the surface of the core rod and the inner wall of the preform rod 101. In the embodiment of the present application, the material of the tube body 1 and the connecting piece 2 can be a flexible material, such as polytetrafluoroethylene. By setting the material of the tube body 1 and the connecting piece 2 as a flexible material, the internal wall of the preform rod 101 will not be scratched when drying the hole in the preform rod 101 and assembling the core rod, thereby ensuring the quality of the core rod and the preform rod 101 and improving the quality of the polarization maintaining optical fiber.
[0042] In the embodiment of the present application, the gas source assembly comprises a plurality of air pipes, a gas source and a plurality of first valves, both ends of each air pipe are connected with the tube body 1 and the gas source respectively, and each air pipe is provided with a first valve. When drying the hole in the preform rod 101, each first valve is opened, and the nitrogen in the gas source enters each tube body 1 through each air pipe to dry the hole.
[0043] Further, the gas source assembly further comprises a pump, and each pump is arranged in an air pipe. When the core rod is adsorbed, part of the core rod is placed in the first tube body 11, the first valve is in a closed state, the pump is opened, the air in each tube body 1 is extracted by the pump, so that each tube body 1 becomes negative pressure to adsorb the core rod. After the core rod is placed in the hole, the pump is closed, the first tube body 11 is separated from the core rod, and then the tube body 1 is pulled out of the preform rod 101.
[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
