Abstract

The invention belongs to the technical field of manufacture of optical fiber image transmission devices, in particular to an optical fiber image inverter rotary torsion processing technology. The invention solves the problem of poor optical fiber image inverter quality brought by a simple torsion method of the optical fiber image inverter in the prior art. The technology comprises the following steps of: driving both ends of an optical fiber composite rod blank in a horizontal state to generate synchronous rotation; meanwhile, heating a optical fiber composite rod to a certain temperature and then starting to apply resistance on a driven shaft to enable the driven shaft to gradually form a certain angle difference with a driving shaft; when the difference reaches 180 DEG C, controlling the rotation speed of the driven shaft to be consistent to the rotating speed of the driving shaft so that the two shafts realize the synchronous rotation; when cooling the optical fiber composite rod blank to plate taking temperature during torsion, shutting down and taking a plate to obtain an image transmission device of which both end surfaces are differed by 180 DEG C. Compared with the prior art, by using the technical scheme, the quality and the torsion qualification rate of the optical fiber image inverter can be improved.

Description

Technical field [0001] The invention belongs to the technical field of optical fiber image transmission device manufacturing, in particular to a rotating and twisting processing technology of an optical fiber image invertor. technical background [0002] The fiber-optic imager is a kind of fiber-optic filaments arranged in a certain rule and heated and extruded. The output end face is rotated 180° around the central axis relative to the input end face, so that the image on the output end face and the image on the input end face are mutually exclusive The inverted fiber optic image transmission device is one of the core components for manufacturing low-light night vision devices. [0003] The existing general production method of optical fiber inverted device is: use static heating, static torsion, that is, the twisted fiber composite rod blank is static relative to the heating furnace when it is heated and twisted, so that the temperature unevenness around the heating furnace and ...
