Automatic glue injection system and manufacturing method of porous ferrule assembly

Abstract

The invention discloses an automatic glue injection system, comprising: a glue injector suitable for injecting glue into a porous ferrule; a first ferrule clamp suitable for clamping the porous ferrule so as to keep the porous ferrule at the a glue station; and a second ferrule clamp, adapted to hold the porous ferrule so as to keep the porous ferrule at the second glue injection station. In the first glue injection station, no optical fiber is inserted into the optical fiber jack of the porous ferrule, and the glue injector injects glue into the porous ferrule that has not yet inserted the optical fiber until the glue fills the entire optical fiber jack; in the second glue injection At the station, an optical fiber is inserted into the optical fiber jack of the porous ferrule, and the glue injector re-injects glue into the porous ferrule that has been inserted into the optical fiber, so as to compensate for the glue lost during the insertion of the optical fiber. In the present invention, the automatic glue injection system can automatically inject glue into the optical fiber insertion hole of the porous ferrule, which improves the glue injection efficiency and improves the manufacturing quality of the optical fiber ferrule assembly.

Description

technical field [0001] The invention relates to an automatic glue injection system for injecting glue into an optical fiber jack of a porous ferrule and a manufacturing method of a porous ferrule assembly. Background technique [0002] Fiber optic connectors generally include a housing and a ferrule assembly assembled in the housing. The ferrule assembly includes a ferrule and optical fibers inserted into the fiber optic jacks of the ferrule. In the prior art, manufacturing a ferrule assembly generally includes the following steps: first, inject glue (or called adhesive) into the ferrule until the glue fills the entire optical fiber jack; then, insert the optical fiber into the ferrule that has been filled glue into the fiber optic socket; finally, heat the glue to cure it, thereby securing the fiber in the ferrule. This produces a ferrule assembly. [0003] In the prior art, artificial methods are generally used to inject glue into the ferrule. The efficiency of manual g...

Problems solved by technology

[0003] In the prior art, the manual method is generally used to inject glue into the ferrule. The efficiency of manual glue injection is low, and it is difficult to accurately control the amount of glue injected, which affects the manufacturing quality of the ferrule assembly and reduces the optical performance of the ferrule assembly.
