[0021] Referring to Figures 1-3 , a visual welding robot with a weld polishing structure, comprising: a welding robotic arm body 1, characterized in that a rotating shaft 2 is installed inside the tail end of the welding robotic arm body 1, an installation frame structure is installed at the driving end of the rotating shaft 2, a welding structure is installed at one end of the installation frame structure, a grinding and polishing structure is installed at the other end of the installation frame structure, and a vision module structure is installed at the bottom of the installation frame structure; the installation frame structure includes: a mounting plate 3, a welding bracket 4, and a grinding bracket 5; the mounting plate 3 is installed at the driving end of the rotating shaft 2, the welding bracket 4 is installed on one side wall surface of the mounting plate 3, and the grinding bracket 5 is installed on the other side wall surface of the mounting plate 3.
[0022] Specifically, the welding structure includes: a welder 6 and welding wire 7; the welder 6 is installed inside the welding bracket 4, and one end of the welding wire 7 is installed at the top end of the welder 6.
[0023] Specifically, the grinding and polishing structure includes: a polishing motor 8 and a polishing brush 9; the polishing motor 8 is installed inside the grinding bracket 5, and the polishing brush 9 is installed at the driving end of the polishing motor 8.
[0024] Specifically, the vision module structure includes: a monocular 3D camera 10 and a red linear light source 11; the monocular 3D camera 10 is installed on the bottom surface of the mounting plate 3, and the red linear light source 11 is installed on the bottom surface of the mounting plate 3.
[0025] Specifically, a locking device is installed inside the rotating shaft 2, which can make the rotating shaft 2 stay at any angle.
[0026] Specifically, the apex angle of the polishing brush 9 is 120 degrees.
[0027] Working principle: When using the present utility model, first connect an external computer to the welding robot arm body 1, and also connect the polishing motor 8, the welder 6, the monocular 3D camera 10, and the red linear light source 11 to the computer respectively. At the same time, connect an external AC power supply to the present utility model to provide energy for the electrical appliances in the present utility model. The operator starts the monocular 3D camera 10 and the red linear light source 11 through the computer. Through a pre-designed program, the red linear light source 11 projects a red straight line onto the welding area. Since there are gaps at the welding area that can cause deformation of the red straight line projection, the position of the welding gap can be judged. The monocular 3D camera 10 performs three-dimensional digital scanning on the welding gap. When the operator controls the welding robot arm body 1 to complete the three-dimensional digital scanning of the welding gap through the computer, at this time, the three-dimensional digital coordinates of the welding gap already exist inside the computer. At this time, the computer automatically drives the tail end of the welding robot arm body 1 to move along the welding gap route, and at the same time, makes the rotating shaft 2 drive the mounting plate 3 and the welding bracket 4 to rotate, and makes the welder 6 perpendicular to the welding gap, so that the welder 6 completes the welding. Then the computer automatically drives the tail end of the welding robot arm body 1 to move along the welding gap route again, makes the rotating shaft 2 drive the mounting plate 3 and the polishing bracket 5 to move, makes the polishing motor 8 and the polishing brush 9 perpendicular to the welding gap, and makes the polishing motor 8 drive the polishing brush 9 to rotate to polish and grind the welded gap, thus completing the processes of welding and grinding.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
