Problems solved by technology
[0003] In the existing optical fiber paralleling equipment, the coating material coated with the optical fiber ribbon is cut off at intervals by a rotating cutter to achieve discontinuous fixation of the optical fiber ribbon, which has potential defects of precise control instability, and the optical fiber has a greater risk of accidental damage; The gear-shaped periodic stopper structure is used to periodically block the uncured adhesive resin coated on multiple optical fiber core wires, which not only makes it difficult to adjust the coating interval, but also easily causes the problem of low utilization rate and waste of the adhesive resin; The vertical rotating guide wheel is impregnated with unhardened adhesive resin while rotating, and the optical fiber is coated with the adhesive resin held in the gap of the spacer plate on the guide wheel. Although it is possible to coat the resin at intervals, the space inside the space The adhesive resin for single storage is quantitative and limited, and the adjustability of the coating interval is also very limited

Embodiment Construction
[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0044] see figure 1 As shown, the present invention provides an embodiment of a flexible optical fiber ribbon manufacturing device. The flexible optical fiber ribbon manufacturing device includes a plurality of spacer coating assemblies 1 and a ribbon assembly 3 .
[0045] A plurality of spaced coating assemblies 1 are used to spacedly coat a plurality of parallel optical fibers 2 along their length direction with adhesive resin. The above ribbon assembly 3 is used for arranging a plurality of optical fibers 2 coated with adhesive resin at intervals in a horizontal and dense manner, and precisely controlling the spacing distance between adjacent optical fibers to form an optical fiber ribbon 4 . Each optical fiber ribbon 4 may comprise 6 optical fibers 2 , 12 optical fibers 2 or 24 optical fibers 2 .
[0046] see Figure 2-6As shown, each i...

The invention discloses a manufacturing device and a manufacturing method of a flexible optical fiber ribbon, which relate to the technical field of optical fiber cables. The adhesive resin is coated at intervals, and the interval coating assembly includes a coating mold and a feed shaft arranged in the coating mold. The two are tightly connected in rotation. material pipe; when the coating hole and the feeding pipe are connected after rotation, the interval coating assembly coats the optical fiber at the outlet of the coating hole with bonding resin; Resin-connected optical fibers are combined to form an optical fiber ribbon. In the present invention, through the high-speed continuous switching between the coating tunnel and the feeding pipeline between the connected state and the non-connected state, the optical fiber at the outlet of the coating tunnel can be coated with adhesive resin at intervals quickly, avoiding damage to the optical fiber, and it is also convenient Adjust the coating interval of the bonding resin.
Description
technical field [0001] The invention relates to the technical field of optical fiber cables, in particular to a manufacturing device and a manufacturing method of a flexible optical fiber ribbon. Background technique [0002] Discontinuously fixed flexible optical fiber ribbon is a new type of close-packed optical fiber ribbon, which is obtained by discontinuously fixing multiple single optical fibers into a ribbon. The flexible optical fiber ribbon is in a discontinuous fixed state between the fibers, so it can be flexibly wound and arranged and can be quickly separated. Compared with the traditional layer twisted loose fiber optical cable, the optical fiber cable with discontinuous fixed flexible optical fiber ribbon It can greatly increase the fiber density, that is, the same outer diameter of the cable can accommodate more fiber cores. [0003] In the existing optical fiber paralleling equipment, the coating material coated with the optical fiber ribbon is cut off at in...
