摘要
Disclosed are a reverse polarity plasma arc robot additive manufacturing system and an implementation method therefor, the system comprising an industrial robot, an additive manufacturing power source, a wire feeding machine, a machine visual system, an industrial computer, a plasma welding gun, a refrigerating device, a gas device and an auxiliary tool fixture. The industrial robot, the additive manufacturing power source, the wire feeding machine, the refrigerating device, the gas device and the auxiliary tool fixture are all connected to the industrial computer via a CAN bus; the machine visual system is connected to the industrial computer by means of a TCP/IP protocol; the plasma welding gun is connected to the refrigerating device, the additive manufacturing power source, the wire feeding machine, the gas device and the auxiliary tool fixture; and the refrigerating device is further connected to the additive manufacturing power source. The additive manufacturing power source comprises a main-arc power source and a pilot-arc power source, and the main-arc power source and the pilot-arc power source are both connected to the plasma welding gun; and the main-arc power source comprises a main-arc power source main circuit and a main-arc power source control circuit, and the pilot-arc power source comprises a pilot-arc power source main circuit, a pilot-arc power source control circuit and a high-frequency and high-voltage arc ignition circuit. The additive manufacturing power source not only realizes the inverse change of the high-frequency and high-efficiency, but also realizes the integration and digital integration of the pilot-arc power source and the main-arc power source. The main-arc power source and the pilot-arc power source are digitally coordinated by means of a CAN network, and the volume of same is compact, the compatibility is better, the field environment is more adaptable, and the expansion capability is stronger.
