Automatic brazing device and method for superfine metal wires and wires

The automatic brazing device comprises a fixing support, a welding unit and an automatic feeding and discharging unit, the fixing support is of a hollow cuboid structure with an opening in the front face, and the left side and the right side close to the lower portion of the bottom are each provided with two rectangular windows; the welding unit is connected to the upper layer in the fixing support. The automatic feeding and discharging unit is connected to the bottom layer in the fixing support and the outer left and right sides. The welding unit comprises an air pipe, a laser controller, a laser transmission channel, a laser heating and melting mechanism, a high-precision visual recognition system, a molten solder jetting mechanism, a high-precision mechanical movement module and a solder heating and melting device. By adopting the scheme that the metal wire makes contact with the wire for pressurization, the welding flux is heated and melted through the non-contact laser heat source, ...
