Abstract

The invention provides an optical fiber and end cap automatic aligning and welding device based on optical power feedback. An upper clamp unit is provided with an upper clamp motion platform and an optical fiber clamp, and the optical fiber clamp is downwards arranged on the upper clamp motion platform; a lower clamp unit is provided with a lower clamp motion platform and an end cap clamp, and theend cap clamp is arranged below the optical fiber clamp through the lower clamp motion platform; a position monitoring unit is provided with a first position monitoring device and a second position monitoring device; an optical power detection unit is arranged below the end cap clamp; and a flame jetting unit is arranged beside the optical fiber clamp and the end cap clamp. The invention furtherprovides an optical fiber and end cap automatic aligning and welding method based on optical power feedback. The device is complete in structure and smooth in operation, and can realize automatic alignment and flame welding of an optical fiber and a glass end cap. Through optical power detection, the alignment precision of the optical fiber and the end cap is effectively improved, and the weldingefficiency of the optical fiber and the end cap is improved.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical fiber end cap automatic alignment fusion splicing device and method based on optical power feedback. Background technique [0002] In high-power laser fiber transmission, the core diameter of the fiber is very thin, and the high-power laser is focused into the fiber through the lens. The power density of the fiber end face is extremely high, and the fiber is easily damaged. Therefore, the fiber end face is required to be free from any damage and pollution, which is extremely demanding; The area of ​​the end face is small, and it is not easy to carry out coating treatment. There is a large loss when the laser enters the end face of the uncoated fiber, which will generate more heat that damages the fiber; the strength of the two ends of the bare fiber is low during the installation and removal process, and the clamping is very uncomfortable. Convenience and...
