Abstract

The invention relates to the technical field of laser welding, and discloses a laser welding head with an automatic wire feeding function, which comprises a laser head, a wire feeding assembly and a support assembly fixed on the wire feeding assembly, the bottom of the wire feeding assembly is fixedly connected with a detection assembly, and the detection assembly comprises a detection plate. The top of the detection plate is in sliding connection with the wire feeding assembly through a sliding rail, and the outer side wall of the detection plate is rotationally connected with a detection wheel; during wire feeding, a welding wire can drive the detection wheel to rotate, so that the rotary encoder on the detection wheel can detect the rotating speed of the detection wheel, and when the rotating speed is lower than or higher than a preset value, the rotary encoder can control the driving equipment through the single chip microcomputer, so that the wire feeding wheel on the driving equipment can adapt to the wire feeding speed according to the detected value; in this way, the wire feeding condition can be automatically monitored, when the wire feeding speed is too fast or too slow or the wire clamping phenomenon occurs, the wire feeding speed can be automatically adjusted, a user is reminded, and maintenance is conducted in time.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a laser welding machine head with automatic wire feeding function. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. Laser welding can be realized by continuous or pulsed laser beam. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. When the power density of laser welding is less than 104W / cm2 ~ 105W / cm2, the laser welding method is thermal conduction welding, and the penetration depth is shallow and the welding speed is slow. When the power density of laser welding is greater than 105W / cm2 ~ 107W / cm2, the metal surface is concave into "holes" under the action of heat, forming deep penetration welding, which has...
