Embodiment Construction

[0036] The present invention is described in detail below in conjunction with accompanying drawing:

[0037] Please refer to Figure 1-9 As shown, the obstacle-crossing all-position autonomous welding robot of the present invention includes a central control system 100 , a communication system 200 , a welding equipment system 300 , a robot motion system 400 , and an intelligent sensor system 500 .

[0038] Please refer to Figures 4 to 9, the robot motion system 400 includes a frame 401, and a mechanical arm 402 composed of multiple joints located above the frame 401 is used to adjust any position and posture within the working range, and any position includes X, Y, and Z directions. The position and posture of the degree of freedom are generated by the movement of each joint of the mechanical arm 402, which realizes the full-position movement of the motion track of the welding workpiece; multiple sets of drive shafts 403 located below the vehicle frame 401, each set of drive...

Abstract

The invention discloses an obstacle-crossing all-position automatic welding robot, which comprises a robot moving system (400), a welding equipment system (300), an intelligent sensing system (500), a central control system (100) and a communication system (200), wherein the robot moving system (400) is used for moving the welding robot, the welding equipment system (300) is used for welding, theintelligent sensing system (500) is used for detecting information about obstacles in front of the welding robot, trailing the position of a welding workpiece and controlling welding quality in real time, the central control system (100) is used for controlling the robot moving system (400), the welding equipment system (300) and the intelligent sensing system (500), and the communication system (200) is used for realizing data communication of the robot moving system (400), the welding equipment system (300) and the intelligent sensing system (500) with the central control system (100). The obstacle-crossing all-position automatic welding robot is capable of automatically crossing obstacles and automatically travelling and welding in an all-position manner.

Description

technical field [0001] The invention relates to a welding robot, in particular to an obstacle-surmounting all-position autonomous welding robot. Background technique [0002] A welding robot is an automated device that can complete welding operations. Welding robots generally use a multi-joint robotic arm to achieve arbitrary position and posture movement in the workspace. In the industry, welding robots generally use magnetic suction welding robots to absorb the surface of the welding workpiece, and then complete the welding task on the welding work surface. Magnetic suction welding robots are generally in direct contact with the workpiece or without direct contact with the magnetic attraction of the welding work to perform welding. For example, Chinese Patent Publication No. CN02079339A discloses a robot for working on the surface of an oil storage tank. This robot is Get in touch with the magnetic welding robot for welding work. Chinese Patent Publication No. CN1739925...
