According to the four-piece optical device coupling welding equipment, overall movement of the light emitting device and the lens can be realized on the premise that overlap welding is not carried out, a new coupling choice is provided, motion errors caused by independent control of the light emitting device clamp and the lens clamp are reduced, and the coupling precision andthe welding quality are obviously improved compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of automatic coupling and packaging of optical devices, in particular to a four-piece optical device coupling welding device based on power and light spot detection. Background technique [0002] With the development of optical fiber communication and optical fiber sensing technology, the preparation of optical transceivers has become the key to the progress of optical information technology. In optical communication products, the demand for optical transceivers such as TOSA-laser emitting devices and BOSA-single-fiber bidirectional products (integrated sending and receiving) is increasing with the development, and its function is mainly to realize the photoelectric conversion of signals. A four-piece optical device is mainly composed of a light emitting component + a lens + a receiving component + an adjustment ring. The main process of its packaging is to first couple and align the light emitting component...

Problems solved by technology

However, for the above-mentioned four-piece optical device, due to the need for multiple coupling alignment and welding to complete power coupling and equalization, the equipment needs to have more complex coupling degrees of freedom to ensure that each component can meet the coupling accuracy requirements

However, the existing optical device coupling welding equipment usually has insufficient coupling degrees of freedom, and the coupling degrees of freedom of each component are relatively independent, and deviations are prone to occur when coupling more than three components at the same time, resulting in a decrease in coupling accuracy and a significant decrease in optical power. Affects the packaging quality of optical devices, especially four-piece high-speed optical devices that require strict coupling accuracy
