Desktop single-station laser soldering machine is composed of a semiconductor laser, a desktop single-station workbench, a visual positioning system and a laser soldering control system. The system is controlled by a touch screen and an industrial computer, with reliable operation and simple operation. The fixture reciprocates into the welding area inside the workbench, and the system automatically positions and welds the product. The operator only needs to install and remove the fixture. This equipment is mainly used in occasions with low speed, light load and low precision requirements. According to the different welding processes of products, different configurations can be matched, and laser solder wire welding and laser solder paste welding can be performed.
