Spot coupling welding equipment for WDM components of box optical devices

Abstract

The invention provides a spot coupling welding equipment for wavelength division components of BOX optical devices, including an upper fixture for clamping a light-emitting component, a lower fixture for clamping a wavelength division component, a coupling detection device, and multiple sets of welding for laser welding The device, the upper fixture and the lower fixture respectively cooperate with the upper fixture movement platform and the lower fixture movement platform to complete the coupling process of the light-emitting component and the wavelength division component, and perform spot detection through the coupling detection device, and an adjustment ring is set on the lower fixture to tighten the fixture , Tighten the adjustment ring to the outside of the light emitter to prevent the adjustment ring from shifting during the coupling process. The present invention adopts spot coupling to complete the coupling, welding and packaging process of the light-emitting component and the box-type WDM component. The clamp is tightened by the adjusting ring to keep the adjusting ring moving synchronously with the light emitter during the coupling process, so as to directly Laser penetration welding is used to effectively improve the coupling accuracy and packaging quality.

Description

technical field [0001] The invention relates to the technical field of automatic coupling and packaging of optical devices, in particular to a spot coupling welding equipment for wavelength division components of BOX optical devices. Background technique [0002] With the development of optical fiber communication and optical fiber sensing technology, the preparation of optical devices has become the key to the progress of optical information technology. In high-speed optical communication products, multi-channel wavelength division components are commonly used, and are usually packaged together with light-emitting components to realize functions such as photoelectric conversion and wavelength division multiplexing. WDM components need to be coupled and aligned with light-emitting components and other components, and used after laser welding as a whole. However, how to improve the performance, quality and reduce costs of optical devices is the key issue in current packaging ...

AI Technical Summary

Problems solved by technology

However, for high-speed optical devices, due to the strict requirements on coupling accuracy, there are few coupling welding equipment that can accurately locate box-type BOX optical devices in the current equipment, and the operation process is simple and effective, making it difficult for the coupling accuracy of optical devices to meet the requirements. It is difficult to further increase the optical power after packaging, which will eventually affect the packaging quality
