The invention relates to an automatic wire feeding
system of an automatic
laser welding machine. The automatic wire feeding
system is matched with a
laser head for use. The automatic wire feeding
system of the automatic
laser welding machine comprises a
welding wire drum, a welding wire correcting mechanism, a welding wire straightening mechanism, an air blowing and wire feeding device, a
tail end wire feeding speed control mechanism and a control driving unit in sequence, wherein the welding wire drum is provided with a wound welding wire, the welding wire correcting mechanism is used for correcting the welding wire, the
tail end wire feeding speed control mechanism is used for precisely controlling the wire feeding speed, the control driving unit is connected with the welding wire correcting mechanism, the welding wire straightening mechanism, the air blowing and wire feeding device and the
tail end wire feeding speed control mechanism and is used for controlling the speed, the air blowing and wire feeding device is provided with a wire blowing
pipe used for blowing and feeding the welding wire and is connected with a wire feeding hole of the wire blowing
pipe, the tail end of the wire blowing
pipe is provided with a welding wire outlet end which is fixedly connected with an end laser head, and the port axis of the welding wire outlet end penetrates through a laser condensation welding focus on the
optical axis of the laser head. The automatic wire feeding system can be used for automatically conveying the welding wire to a welding point, and operating personnel do not need to convey the welding wire by hand, so that the condition that time and effort are consumed due to the fact that the welding wire is manually and imprecisely conveyed is avoided, the labor cost is reduced, the welding quality is conveniently ensured, and the application range of the laser welding
machine is enlarged.
