Description
Technical Field
The invention relates to the technical field of optical fiber cables, in particular to an optical fiber ribbon coating device, a production system and a manufacturing method.
Background
With the increasing demand of the current market for optical cables with large core number, the optical fiber ribbon optical cable becomes the first choice of the optical cable with large core number due to the characteristics of large core number, high density, convenient splicing, easy branching and the like, so that the identification problem of the ribbon optical fiber in the optical fiber ribbon optical cable is particularly important.
Identification of optical fiber ribbons in a ribbon stack is accomplished in two ways: the optical fiber ribbon identification method is characterized in that different optical fiber ribbons are identified through printing identification on each optical fiber ribbon, and different optical fiber ribbons are identified through reference optical fibers (pilot optical fibers) in the ribbons.
Currently, the printing identification is the main identification method. The printing method of the mark includes code spraying, impression and the like, and the most used method is code spraying printing. However, at present, inkjet printing often faces three embarrassing dilemmas: firstly, the jet printing sensitivity of the ink jet printer is limited, and jet printing information becomes distorted and unclear when the tape production speed exceeds 400 m/min; secondly, the printing ink is not resistant to alcohol wiping; third, the printing ink is not resistant to high temperature, and printing information can migrate between adjacent optical fiber ribbons at high temperature. In particular, with current ink jet printer inks, inks that resist alcohol wiping do not resist migration, and inks that resist migration do not resist alcohol wiping.
In view of the above defects of code-spraying and printing, the production speed is limited, and the printing speed cannot keep up with the production speed, resulting in waste of productivity. Secondly, the alcohol wiping resistance and migration resistance of the jet printing ink for printing cannot be simultaneously achieved, and the long-term and stable printing effect is difficult to achieve in terms of identification. And there is currently no convenient, economical solution to these drawbacks.

a positioning die (116) in communication with an output end of each of the first die cavities (113) and an input end of the second die cavity (114);
a sizing die (117) in communication with an input end of each second die cavity (114).
10. A method of manufacturing optical fiber ribbons using the optical fiber ribbon production system of claim 7, comprising the steps of:
the paying-off unit (2) conveys a preset number of optical fibers to the pre-coating cavity, the feeding mechanism injects colorless resin into the pre-coating cavity from a colorless resin feeding hole (121), and the colorless resin in the pre-coating cavity flows into the coating cavity;
positioning the optical fiber through the ribbon combining mold, and conveying the optical fiber to a coating cavity through a pay-off unit (2);
the feeding mechanism injects colored resin into the coating cavity from a colored resin feed opening (122) to coat the marking line;
combining the optical fibers in a coating bin to obtain a preformed optical fiber ribbon, and conveying the preformed optical fiber ribbon to a curing unit by a pay-off unit (2) for UV curing to shape the optical fiber ribbon;
and the paying-off unit (2) conveys the shaped optical fiber ribbon to the take-up unit for coiling.
