The structure of the optical fiber welding machine,

The structure of the optical fiber welding machine - 2016 06 - 01 by the high voltage source control device, discharge electrode, optical fiber, controller, microstructure, and the heater ( Hot stove) Such parts. 1, high voltage source: dc, ac power supply to 3 ~ 4 kv high-voltage, about 20 ma current for high voltage power supply. Another is up to 20 KHZ or 40 KHZ high frequency power supply. 2, discharge electrode: by gold tungsten rod processed into a pair of electrodes, tipped with 30 degrees conic installed on the electrode on the shelf, electrode tip interval is commonly 0. 7mm。 When switching high voltage source, they produce arc, make in the center of the arc fiber melt into one. The service life of the electrode is usually 1000 times. Electrode consume excessive still continue to use, will increase the loss of connection. 3, optical adjustment device: the fine tuning of V groove is by installing the micrometer screw on the long bar end. Of optical fiber, placed on V groove get fixed by mechanical press plate. Two directions of X, Y, fine-tuning and fiber Z axis are orthogonal. Fine tuning range respectively in & plusmn; More than 10 um, regulate the precision & plusmn; 0. 1mm。 4, controller, including in the unit and microprocessor, microprocessor used to complete the automatic adjustment, the premelting, welding and connection loss estimation, etc. 5, microscope ( The optical system) : used to help to observe the state of the fiber and welding quality. 6, heater ( Hot stove) : used for heat shrinkable heat shrinkable tube, increase the fiber connection strength.
