The invention discloses an intelligent automobile paint spraying and baking integrated robot which comprises a master control workstation, a laser scanning unit, a CCD image collecting and processing unit, an exhausting and dust removing constant-temperature system unit, a paint spraying mechanical arm unit, a paint spraying automatic moving trolley unit, a paint baking mechanical arm unit, a paint baking automatic moving trolley unit, a wireless network and a power supply system unit. Wheels of an automatic moving trolley move on a circumference track, a method for moving double mechanical arms for cooperative paint spraying and baking is adopted, and an unmanned, non-cable and non-wire intelligent paint spraying and baking technology is achieved by adopting a rail power supply mode and a wireless network communication mode. A laser scanning technology and a graph and image modeling technology are merged for digitalizing automobile repairing; and local paint spraying and local baking are conducted, the maintaining efficiency is greatly improved, the labor cost is reduced, harm of paint mist to a human body is reduced, and intelligent unmanned paint spraying and baking integrity of local automobile repairing is achieved in a real sense.
