Problems solved by technology

In the prior art, there are certain welding gaps in the overlapping welding of BASE and the adjustment ring, and it is difficult to achieve uniform welding seam
The lap welding is placed in the last welding process of the three-piece coupling welding of optical devices, and the power welding becomes larger, so the yield rate is lower

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0027] In the coupling welding production of optical devices, the welding transformation control is very important, which directly affects the production yield. As mentioned above, because the adjustment ring and the laser (LD) are first welded by penetration welding, and then the adjustment ring and the base (BASE) are welded by lap welding, there is a problem that the upper chuck and the lower chuck are coaxial The requirement of high degree of welding is high, which causes the problem of...

Abstract

The embodiment of the invention provides an optical device coupling welding method. The method comprises the steps of clamping a laser on an upper chuck, and clamping a substrate on a lower chuck; providing an adjusting ring, and sleeving the part, extending out of the upper chuck, of the laser with the adjusting ring; adjusting the upper chuck and the lower chuck to enable the laser and the substrate to reach the maximum coupling value; overlapping and welding the adjusting ring and the substrate by using first welding energy; overlapping, welding and fixing the adjusting ring and the substrate by using second welding energy, wherein the second welding energy is greater than the first welding energy; and welding the adjusting ring and the laser in a penetration welding mode. According tothe method, the welding deformation influence caused by coaxiality of the upper chuck and the lower chuck can be reduced, meanwhile, the welding procedure is simplified, and the welding efficiency isimproved.

Description

technical field [0001] The present application relates to the technical field of optical devices, in particular to an optical device coupling welding method. Background technique [0002] In the coupling welding production of optical devices, the welding transformation control is very important, which directly affects the production yield. Welding change = (post-welding optical power - pre-welding coupling optical power) / pre-welding coupling optical power, that is, the smaller the welding change, the better. The smaller the welding change, the smaller the optical power lost during welding. At present, in the optical device coupling welding process, usually after the coupling is completed, the adjustment ring and the laser (LD) are first welded by penetration welding, and then the adjustment ring and the base (BASE) are welded by lap welding. [0003] One of the reasons for the welding change is that since the lap welding is a horizontal welding, the coaxiality of the uppe...
