Partially Automated Processing Line
The processing line is designed for the production of high-quality fiber optic cables, for example, for the automotive industry. High-precision welding connections with low light attenuation are made on the prepared fibers.
The special properties of plastic optical fibers require parameters and processes specifically tailored to the material. The processing line is equipped with a pay-off reel with storage, a cutting machine, and a laser welding module, and can be expanded with quality assurance devices.
Preparations for Cable Production
The nearly tension-free feeding of the optical fibers is achieved through a specially developed cable pay-off system. The speed of the unwinding is adjusted according to demand, and a corresponding length of fiber is held in storage. The product-dependent fiber lengths are cut at the first station of the cable processing plant.
A high-quality end face of the fiber is crucial for achieving the desired low light attenuation in the produced fiber optic cable. The cutting process simultaneously creates the ideal surface for optical transmission, eliminating the need for additional processing. Internal suction removes unwanted plastic particles in quality-relevant process areas.
Connecting with Contacts
The connection of the fibers with fiber optic connectors takes place at the welding module of the processing line. Standard fiber optic ferrules, as well as special pin and socket contacts (pigtails) and housings, can be attached. For quality assurance, the position of the fiber relative to the ferrule and the light attenuation of each produced weld connection are measured and monitored.
The processing plant can be equipped with customer-specific extensions and is suitable for smaller series. The high-quality components, robust design, and modular structure ensure high flexibility, short setup times, and long-lasting durability.
Overview of the Overall Process
The production of fiber optic cables involves several process steps, with an operator feeding the prepared fibers into and removing them from the welding module.
