Abstract


Industrial robots welding is one of the areas most important, as foreign and domestic demand for industrial robots in the welding research applications, China has also started a welding robot research applications. After years of development and reform, China's welding robots have been used in various production areas. Robotized machine refers to the introduction of traditional mechanical robot technology, it has functions of the robot. Of course, the machine can also be called the intelligent robotic machines or intelligent machinery. Robotics, namely mechanical, electrical, hydraulic, telecommunications integration technology is to enhance the level of China's overall mechanical technology and product quality of the important means. The subjects of the concept of robotic machines and ideas, with the cooperation of a motor manufacturers, design and manufacture of robotic welding unit motor housing. According to the characteristics of the actual production is proposed to solve the problem of the two options: Normal fixture with six degrees of freedom articulated robotic solutions, dedicated fixture with Cartesian robot solutions. According to the site characteristics of the production environment and welding requirements, comprehensive comparison of pros and cons of the two programs, the choice of a dedicated fixture with two degrees of freedom Cartesian robot robotic solutions. Solution in a conventional robotic welding equipment motor housing, based on the integration of robotics and automation control module and the motor housing design special fixtures, so that it can adapt to a variety of specifications of the motor housing, welding, electrically casing welding production flexibility and agility. In accordance with the characteristics of the welding process and field production, the paper welding equipment control system has been designed according to the requirements of the drive system, the motor selection were calculated and analyzed, and its controller are discussed. The core thesis is that the mechanical system and control system integrated design, the use of PLC and robot controller coordination and control, to achieve automation of welding equipment, and it has the function of the robot, which is a focus of this article. In addition, the welding operation, the interference variety of factors, of which the most prominent is the electromagnetic interference in the actual commissioning of the project encountered many problems, the paper from the power supply interference suppression, shield grounding, relay interference from other aspects of the control system software and hardware systems for the analysis and debugging, and power filtering for simulation, put forward measures to suppress interference. Finally, the article describes the robotic welding cells in the production of the motor housing to the actual operation situation, and for the practical application effect analysis, proposed future improvement ideas.
