An optical fiber fusion splicing heat shrink protection sleeve assembly device

Abstract

The invention discloses a fiber splicing thermal shrinkage protective casing assembly device. The fiber splicing thermal shrinkage protective casing assembly device comprises a steel pin separating and conveying device (1), a hot melting pipe conveying and cutting device (2), a work-piece carrier base (3), a pushing device (4) and an assembly device body (5). The work-piece carrier base (3) is provided with a U-shaped groove (31). The steel pin separating and conveying device (1) is installed on the work-piece carrier base (3). The pushing device (4) is installed on the steel pin separating and conveying device (1). The hot melting pipe conveying and cutting device (2) and the work-piece carrier base (3) are installed on the assembly device body (5). The steel pin separating and conveying device (1) separates out one steel pin (8) to the bottom of the U-shaped groove (31). The hot melting pipe conveying and cutting device (2) conveys a hot melting pipe (9) of fixed length into the U-shaped groove (31) to be cut off, the pushing device (4) pushes the hot melting pipe (9) to the steel pin (8), and the assembly device body (5) pushes the steel pin (8) and the hot melting pipe (9) into a thermal shrinkage pipe (10) at the same time. The fiber splicing thermal shrinkage protective casing assembly device achieves automatic assembly and production and is high in production efficiency.

Description

technical field [0001] The invention relates to the field of machinery, in particular to the field of mechanical automation, in particular to an assembly device for an optical fiber fusion splicing heat-shrinkable protection sleeve. Background technique [0002] When performing fusion splicing on the optical fiber, it is necessary to remove the protective layer at the connecting end of the optical fiber to expose the optical fiber for fusion splicing. The removed optical fiber protective layer has a certain mechanical strength, which reduces the mechanical strength of the optical fiber connection due to the absence of the optical fiber protective layer. Therefore, the optical fiber fusion heat-shrinkable protective sleeve with steel needles came into being. However, traditional optical fiber fusion splicing heat-shrinkable protective sleeves are assembled manually, because the outer diameter of the heat-shrinkable tube in the inner layer of this optical fiber fusion-spliced ...

AI Technical Summary

Problems solved by technology

The removed optical fiber protective layer has a certain mechanical strength, which reduces the mechanical strength of the optical fiber connection because there is no optical fiber protective layer. Therefore, the optical fiber fusion heat shrinkable protective sleeve with steel needles came into being.

However, traditional optical fiber fusion splicing heat-shrinkable protective sleeves are assembled manually, because the outer diameter of the heat-shrinkable tube in the inner layer of this optical fiber fusion-spliced ​​heat-shrinkable protective sleeve is not much different from the inner diameter of the outer heat-shrinkable tube. There is a steel needle to enhance the mechanical strength between the heat-melt tube and the heat-shrinkable tube, so it is difficult to manually assemble this kind of fusion fiber protection tube, and the production efficiency is also very low
