Uses the micro welder and the said micro welder the welding process

摘要

Fusion-splicing machine for optical fibres, consisting of a frame (1) comprising a central support surrounded by two lateral supports (5, 5') called beams, these beams being capable of moving under the action of a bending moment about an axis X, the frame also supporting:… means for solidly fixing the optical fibres to the beams,… means (12, 12') for precisely guiding the fibres on the central support,… first means (24, 24') for moving the beams, with low precision, in order to bring the fibres into contact, end to end, by means of a relative translational movement along their longitudinal axis Z orthogonal to the axis X, (micrometer screws),… second means (25, 25') for moving the beams, with high precision, in order to set the fibres into precise relative translational movements along the axis Z, (cams),… two fusion-splicing electrodes,… an optical device (27) for observing the ends of the said optical fibres which comprises a microscope,… characterised in that the second movement means (25, 25') enable a continuous cycle of relative translational movements of the fibres (F,F') to be carried out along the axis Z in both directions, and in that the optical device comprises means enabling, in combination with the microscope (27), one and the same image of the optical fibres (F,F') to be obtained before and after fusion splicing, for two mutually orthogonal viewing axes. …IMAGE…
