Packaging system suitable for sensing unit in metal spiral armored sleeve

Abstract

The invention discloses a packaging system suitable for a sensing unit in a metal spiral armored sleeve. The packaging system comprises an air source assembly, a glue injection mold, a clamping unit, a tensioning unit, a glue injection unit and a curing unit. The two ends of the sensing unit coated with the metal spiral armored sleeve are movably clamped by the clamping ends of the tensioning unit, and the tensioning state of the sensing unit is changed in the axial direction through the tensioning unit. The glue injection mold is movably arranged at the movable clamping end of the glue injection unit, and when the glue injection mold clamps the position to be packaged, the glue injection unit injects curing glue between the metal spiral armored rotating sleeve and the sensing unit; and after the stations of the glue injection unit and the curing unit are switched, the curing unit is used for curing the curing glue. According to the invention, through cooperative arrangement of the above components, automatic packaging of the sensing unit in the metal spiral armored sleeve is realized, the production efficiency is significantly improved, the curing consistency of a packaged product is significantly improved, and large-scale popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of optical fiber sensing, in particular to a packaging system suitable for sensing units inside metal spiral armored sleeves. Background technique [0002] At present, in the field of optical fiber distributed sensing technology, the packaging structure of the sensing unit of the metal spiral armored sleeve has been changed by technical workers in the field because of its light weight, strong lateral pressure resistance, rat bite resistance, and high degree of automated production. Favor, in the application of optical fiber temperature field monitoring, this kind of optical cable forming method with spiral armored sleeve structure is widely used. [0003] In the application of optical fiber temperature field monitoring, the packaging form of this spiral armored sleeve is adopted, and the internal sensing unit is in a free contact state, which is relatively easy to realize, so it has been widely used. In rec...
