The optical fibers 200 are then transported using an external device, such that one optical fiber 200 is inserted into one of the sub-conduits 820, another optical fiber 200 is inserted into the other sub-conduit 820, the external device continues to transport the optical fibers 200, and the two optical fibers 200 are collected in the main conduit 810 and inserted into the connector 100 through the inlet 420. At this time, the driving motor 710 is started, the driving motor 710 drives the pushing disk 720 to rotate, the pushing disk 720 drives the pushing rod 730 to move, the pushing rod 730 is abutted to the connector 100, the pushing rod 730 pushes the connector 100 towards the direction of the outlet 430, and during the process that the pushing rod 730 pushes the connector 100, other devices outside continue to transmit the optical fiber 200, so that the optical fiber 200 moves along with the connector 100. Finally, the connector 100 is moved to the outlet 430, the impact hole 110 is aligned with the impact rod 520, and the glue injection hole 130 is aligned with the glue injection nozzle 620.
Then the first cylinder 510 is started, the first cylinder 510 drives the impact rod 520, the impact rod 520 impacts the pre-tightening piece 120, the pre-tightening piece 120 deforms and abuts against the optical fiber 200, the second cylinder 621 is started, the second cylinder 621 drives the glue injection nozzle 620, the glue injection nozzle 620 is inserted into the glue injection hole 130, then the glue supply machine 630 is started, the glue supply machine 630 supplies glue into the glue supply pipe, the glue in the glue supply pipe enters the connector 100 through the glue injection nozzle 620, the connector 100 is fixedly connected with the optical fiber 200 through the glue, and therefore production of the double-core pigtail is completed.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
