1. Mobile Robot (AGV)
Mobile robot (AGV) is a type of industrial robot that is controlled by a computer and has functions such as mobility, automatic navigation, multi-sensor control, network interaction, etc. It can be widely used in flexible handling and transmission in industries such as machinery, electronics, textiles, cigarettes, medical, food, paper, etc. It is also used in automated three-dimensional warehouses, flexible processing systems, etc Flexible assembly system (using AGV as the active assembly platform); It can also be used as a transportation tool in the sorting of items at stations, airports, and post offices. One of the new trends in the development of international logistics technology is mobile robots, which are the core technology and equipment. They use modern logistics technology to cooperate, support, transform, and enhance traditional production lines, achieve point-to-point automatic access to elevated box storage, operation, and transportation, achieve refinement, flexibility, informatization, shorten logistics processes, reduce material loss, and reduce floor space, Reduce construction investment and other high-tech and equipment.
2. Spot welding robots have the characteristics of stable performance, large workspace, fast movement speed, and strong load capacity. The welding quality is significantly better than manual welding, greatly improving the productivity of spot welding operations. Spot welding robots are mainly used for welding the entire vehicle, and the production process is completed by major automobile manufacturers. International industrial robot companies, relying on their long-term cooperative relationships with major automotive companies, provide various types of spot welding robot unit products to major automotive production enterprises and enter China in the form of welding robots and vehicle production lines, occupying a dominant market position in this field. With the development of the automotive industry, welding production lines require the integration of welding tongs and an increasing weight. The 165kg spot welding robot is currently the most commonly used robot in automotive welding. In September 2008, the Robotics Research Institute developed the first 165kg level spot welding robot in China and successfully applied it to the Chery automotive welding workshop. In September 2009, the second robot, which had undergone optimization and performance improvement, was completed and successfully passed acceptance. The overall technical indicators of the robot have reached the level of similar foreign robots.
3. Arc welding robots are mainly used in the welding production of various automotive components. In this field, international large-scale industrial robot production enterprises mainly provide unit products to complete equipment suppliers. Key technologies include: (1) Optimization and integration technology of arc welding robot system: The arc welding robot adopts AC servo drive technology and high-precision, high rigidity RV reducer and harmonic reducer, which have good low-speed stability and high-speed dynamic response, and can achieve maintenance free function. (2) Coordinated control technology: Control the coordinated movement of multiple robots and displacement machines, which can maintain the relative posture of the welding gun and the workpiece to meet the requirements of the welding process and avoid collisions between the welding gun and the workpiece. (3) Accurate weld seam trajectory tracking technology: Combining the advantages of offline working methods of laser sensors and visual sensors, laser sensors are used to achieve weld seam tracking during the welding process, improving the flexibility and adaptability of welding robots for complex workpieces. The residual deviation of weld seam tracking is obtained through offline observation of visual sensors, and compensation data is obtained based on deviation statistics and robot motion trajectory correction is carried out, The best welding quality can be achieved under various working conditions.
4. Laser processing robot Laser processing robot applies robot technology to laser processing, and achieves more flexible laser processing operations through high-precision industrial robots. This system can be operated online through a teaching box or programmed offline. This system generates a model of the processed workpiece through automatic detection, and then generates a machining curve. It can also directly process using CAD data. It can be used for laser surface treatment, drilling, welding, and mold repair of workpieces.
