Therefore, TX coupling and RX coupling during optical communication are very important processes. Traditional production processes have high requirements for operators. Coupling is mainly carried out manually, with low efficiency and low yield. The existing automatic coupling machines on the market can reduce the labor intensity to a certain extent and improve the yield, but there are still problems such as low working efficiency. Frequent loading and unloading of workpieces not only increases the labor cost but also reduces the service life of the workpieces to a certain extent, and continuous coupling welding cannot be achieved. Currently, during the coupling and welding process of optical devices, usually after 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. During coupling, high coaxiality requirements are imposed on the laser and the base, and deviations are likely to occur during the coupling process. During welding, there are certain welding gaps in the lap welding of the base (BASE) and the adjustment ring, and it is difficult to achieve uniform weld seams, resulting in a low yield.
