1. Welding robot weld seam tracking technology
In the welding process of the welding robot, the welding torch deviates from the weld due to the influence of various factors such as strong arc radiation, high temperature, smoke and dust, sputtering, groove conditions, machining errors, fixture accuracy, surface state and thermal deformation of the workpiece. Welding tracking technology requires the arc welding robot to detect the welding deviation in real time according to the changes in welding conditions, adjust the welding path and welding parameters, and ensure the reliability of the welding quality.
The welding tracking technology is mainly based on sensor technology and control theory methods, and the research of sensing technology is mainly based on arc sensors and optical sensors. The arc sensor directly extracts the welding position deviation signal from the welding arc itself, with good real-time performance, flexible welding torch movement, and the welding process meets the requirements of low-cost automation, which is suitable for melting electrode welding. The basic principle of arc sensing is to detect the height of the torch and the deviation from side to side.
2. Welding robot offline programming and path planning technology
The welding robot offline programming system is an extension of the robot programming language. It uses computer graphics to build a robot model and working environment, uses some programming algorithms to control and manipulate the graphics, and then does not use actual robot programming. At the heart of the automatic programming technology is the planning of welding tasks, welding parameters, welding paths and tracks.
For the application of arc welding robots, automatic programming technology can be said to be an independent programming task technology, which can help programmers complete in all stages of programming, with the characteristics of high intelligence and high programming quality. The ideal goal of the offline programming technology is to achieve automatic programming, i.e., the expert system in the offline programming system will automatically formulate the corresponding process, thus generating the entire process of the welding robot program.
3. Multi-robot coordinated control technology of welding robot
A welding robot multi-robot system refers to a multi-robot integrated system that completes a task through coordination and coordination. It includes two aspects: multi-robot cooperation and multi-robot coordination.
When given the task of a multi-robot system, the first question is how to organize multiple robots to complete the task, how to assign the entire task to the welding robots of each member, that is, how to cooperate between the robots. Through some mechanism to determine the respective tasks and relationships, the question is how to maintain the coordination of the robot's movements, i.e., multi-robot coordination. The coordination problem is particularly acute because of the complex task composed of coupled subtasks.
