The invention belongs to the technical field of laser processing, and particularly discloses a laser welding robot, which comprises a frame, a laser welding component and a protective component, wherein the protective component comprises a protective box, and through holes are formed on the left and right side walls of the protective component. Clamping mechanisms are rotatably connected to the left and right side walls of the protection box, rotating shafts are rotatably connected between the left and right side walls of the protection box, both ends of the rotating shafts are respectively connected with two clamping mechanisms through transmission mechanisms, a downward extending air cylinder is arranged on the bottom wall of the protection box, a piston is hermetically and slidably connected in the air cylinder, a crank-slider mechanism for driving the piston to reciprocate is arranged in the middle of the rotating shaft, a slag suction pipe is communicated between the air cylinder and the inside of the protection box, a first air pipe is communicated with the upper part of the air cylinder, and a second air pipe is communicated with the lower part of the air pipe. According to the scheme, when the rotating shaft rotates, the piston is driven to reciprocate by the crank-slider mechanism, so that the flue gas and welding slag in the protective box are treated and the production environment is protected.
