Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical fiber cable equipment, and particularly relates to a cable optical fiber binding device. BACKGROUND

[0002] In the fields of power communication, rail transit, building wiring, etc., the binding and twisting of cables and optical fibers is a key process to ensure the stability of signal transmission and the normative of line layout, and the corresponding cable optical fiber binding device has become a commonly used device in the industry. The cable optical fiber binding device in the prior art usually comprises a support shaft, a wire roller, an optical fiber guide disc, a twisting device and a driving mechanism, etc. The working logic is that the driving mechanism drives the support assembly to rotate, so that the cable and the optical fiber are transported to the twisting device through the guide structure to complete the winding and binding. To ensure the stability of the cable conveying path, a through hole structure is usually provided on the optical fiber guide disc, the wire roller and other components to limit and guide the cable and the optical fiber, so as to ensure that the two are twisted at a predetermined angle. However, the design focus of the existing binding device is mostly on the twisting precision and the overall structural stability, and there is a lack of adaptive design for the key link of cable passing through the hole, and there is a lack of targeted auxiliary structure support.

[0003] In actual application, the existing cable optical fiber binding device has defects in the design of the optical fiber passing through the hole. The oil stains and impurities on the surface of the optical fiber not only directly increase the threading resistance, but also pollute the inner wall of the through hole and accumulate dust and debris, which further causes the subsequent optical fiber to be stuck, and the hard debris can scratch the optical fiber coating. The residual impurities also affect the twisting tightness of the optical fiber and the cable, and long-term use can cause optical signal attenuation. On the other hand, the threading process relies on manual operation, and even if the number of through holes is not large, the optical fiber end can be easily stuck at the edge of the through hole if there is slight bending or burr. Manual adjustment not only consumes time and effort, but also can cause damage to the optical fiber coating and the end, which seriously affects the threading efficiency and the quality of subsequent binding and signal transmission.
