Common fault problems and solutions of welding positioner
From the macro perspective, the development of positioner technology is generally in two directions. One is for the quality control of the welding process, such as improving the accuracy of the welding track, etc., and improving the welding quality from the perspective of the welding process. The second is the expansion of the operating capacity of the positioner, which belongs to this category. In essence, the positioner is an extension of the freedom of operation and an extension of the operation space.
The application of the positioner makes the welding robot more flexible in operation, and the size of the welding workpiece is theoretically no longer limited by the working space of the robot itself. The emergence of positioners largely compensates for the limitations of past welding operations. It can be said that the positioner has become a new pivot for the positioner to break through its own limitations. There is no doubt that the key to the successful application of the positioner is the coordinated control with the welding robot. In layman's terms, it is effective cooperation between the two.
For a long time, due to the difference in the developmental level of the manufacturing industry and the weak research.. There has been no special work to study the definition and classification of welding positioners, so their titles and functional classifications are also different. To this end, we need to give the welding positioner a professional definition, that is, the equipment used to drag the workpiece to be welded to move the weld of the workpiece to the ideal position for welding. Specifically, the welding positioner can make the welding seam to be welded in any position of the loaded workpiece by returning to the position or linearly changing the position. According to the specific welding needs, it can quickly become the welding of the foot welding and the flat welding into the flat fillet welding. Operations, thereby changing the welding operations that may require vertical welding, overhead welding, etc., which are difficult to guarantee the welding quality.
The working status of the system will be fed back through the motion controller and displayed on the industrial computer display interface in real-time. Thanks to the open software and hardware architecture, the operator can easily implement different configuration strategies by changing related programs, such as the number of specific control axes, trajectory planning strategies, and motion control strategies. At present, many scientific research units have done in-depth research on the motion control of the positioner system and obtained a series of important results. If an integrated control system based on an open architecture is implemented from the beginning, it will undoubtedly create convenience for these research results. Conversion platform. Through this integrated professional control system, the trajectory of the positioner and the positioner can be planned in advance during the initial period of welding, so that better cooperation between the two can be achieved in the operation project.
The positioner is a relatively young product, which is indispensable to the welding industry. With the positioner as the core, the welding processing system integrating the positioner and other equipment greatly improves the efficiency of my country's industrial manufacturing. At the same time, the key technology of this integrated equipment is also necessary to further improve the level of welding equipment manufacturing and welding processing technology in my country. Among these technologies, the positioner body and positioner coordinated control technology has outstanding application value. It enables welding operations that require vertical welding, overhead welding, etc., which are difficult to ensure welding quality, thereby ensuring welding quality and improving Welding productivity and production process safety.
