Description

Technical Field

[0001] This utility model relates to the field of fiber optic communication technology, and in particular to an automatic fiber optic gluing and fiber optic splicing machine. Background Technology

[0002] In recent years, with the continuous development of artificial intelligence and intelligent computing centers, the number of active optical module products has increased explosively. From the current large-scale commercial use of 100G, 200G, 400G and 800G active modules to the gradual small-batch trial installation of 1.6T in the future, the optical ports of these active modules need to be connected by optical fiber ribbons composed of multiple single-core optical fibers, namely multi-core optical fiber ribbon short patch cords and multi-core AOC optical patch cords.

[0003] The aforementioned multi-core connector has a process in its production where multiple single-core optical fibers are combined into an optical fiber ribbon. This process is typically done manually, with workers applying fast-drying or silicone-based adhesives to the single-core fibers before using specialized clamps. The quality of this process depends heavily on the workers' skills and experience. During this process, issues such as fiber overlap, fiber scattering, and uneven adhesive thickness frequently occur, leading to fiber failure or product scrap. Furthermore, the adhesive needs to cure after application, severely impacting production efficiency and occupying significant production space.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design an automatic fiber gluing and fiber splicing machine. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide an automatic fiber bonding and fiber splicing machine, which solves the problem that fiber splicing depends on the skill level and experience of workers, reduces splicing failure or product scrap caused by fiber splicing, fiber scattering, and uneven glue thickness, improves production efficiency and reduces the occupation of a large amount of production space.

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic fiber optic gluing and splicing machine, which includes a base, cable clamps, a drive structure, a moving block, a splicing support, a splicing gluing clamp, a curing device, a sensing device, and a dispensing device.
