Coupling welding equipment and method for coaxial collimator

Abstract

The invention provides coupling welding equipment for a coaxial collimator. The coupling welding equipment comprises a laser welding gun assembly, an upper clamp assembly, an adjusting ring abutting assembly, a lens clamp assembly and a detection and analysis assembly, an optical fiber adapter is clamped and positioned by the upper clamp assembly, a lens is clamped and positioned by the lens clamp assembly, an adjusting ring is arranged on the optical fiber adapter in a sleeving manner, and the adjusting ring abuts against the optical fiber adapter through the adjusting ring abutting assembly; and the coupling welding device further comprises a reflecting mirror assembly which has multiple degrees of freedom of motion, a reflecting mirror is moved and positioned below the lens, and emergent light of the lens is reflected to the detection and analysis assembly. All devices of the collimator can be vertically and coaxially positioned, annular operation of the laser welding gun assembly is facilitated, a coaxial emergent light path is reflected to the detection and analysis assembly under the action of the reflecting mirror, the detection and analysis assembly can be horizontally arranged, it is ensured that an enough distance is reserved between a near-field position and a far-field position, and the equipment installation and arrangement convenience and the coupling accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of collimator packaging, in particular to a coupling welding device and method for a coaxial collimator. Background technique [0002] The collimator is an optical element used for input and output of optical fiber communication optical devices. Its structure is relatively simple, including fiber optic adapters and lenses. The divergent light emitted by the optical fiber becomes parallel light (Gaussian beam) through the front lens. To couple light into the desired device with maximum efficiency or to receive light signals with maximum efficiency. In the coaxial collimator, the fiber optic adapter and the lens are located on the same optical path line. Based on the characteristics of the parallel light output, the fiber optic adapter and the lens need to be coupled and packaged by welding the adjustment ring.

AI Technical Summary

Problems solved by technology

Since the coaxial collimator needs to complete multiple annular welding of the fiber optic adapter, adjustment ring and lens, the device needs to be positioned vertically and coaxially to facilitate the circular operation of the welding torch, and multiple annular welding also brings new coupling and detection Difficulty, the above scheme is not suitable for coupling package of coaxial collimator
