Autonomous mobile robot system for spot welding of passenger car side wall skin, and working method

Abstract

The invention relates to the technical field of car body skin welding, in particular to an autonomous mobile robot system for spot welding of a passenger car side wall skin and a working method. The autonomous mobile robot system for spot welding of the passenger car side wall skin comprises a truss manipulator system, a control system and a single-face double-spot welding system, wherein the single-face double-spot welding system comprises a single-face double-spot welding machine; the truss manipulator system comprises a truss steel structure and a manipulator mechanism which is arranged onthe truss steel structure and used for moving the single-face double-spot welding machine; and the control system comprises a demonstrator, a truss manipulator control box and a single-face double-spot welding machine control box. The autonomous mobile robot system for spot welding of the passenger car side wall skin provided by the invention can not influence existing equipment and personnel operation space, is suitable for arrangement shapes of skin welding spots of various different vehicle types, has the functions of automatic locating and automatic moving of the positions of the welding spots, achieves automatic spot welding of the passenger car side wall skin, is beneficial to reducing the labor intensity of operators, and is high in production efficiency, uniform in welding spot distribution and good in welding quality.

Description

technical field [0001] The invention relates to the technical field of body skin welding, in particular to an autonomous mobile robot system and working method for spot welding of passenger car side wall skin. Background technique [0002] The welding of the side skin of passenger cars mainly adopts CO2 gas shielded welding, plug welding and resistance spot welding. The resistance spot welding process is used. [0003] At present, the spot welding of the side skin is mainly manual spot welding, using a single-side single-spot welding machine or a single-side double-spot welding machine. [0004] However, manual spot welding has high labor intensity and low production efficiency, and the distribution of solder joints is unstable, so the welding quality cannot be guaranteed. [0005] For example, the patent application number is 201721082886.4, and the application date is August 28, 2017. It is a utility model patent named "An automatic welding system for body skin". The mai...
