Our AC servo motion control products is still in its infancy, but the growing presence of the system to show, is widely used in machinery in various industries to enhance the level of intelligent control industry, market demand significant, increase in the next few years, glue stick the space is very large.
In the servo system, AC servo motion control system is the largest branch, which is a combination of electrical science, automatic control, electrical technology, mechatronics, computer-controlled integrated system. In actual production, the use of AC servo motion control products, positioning can solve complex control problems, such as the robot trajectory control, position control,glue gun CNC machine tools, and that in processing machinery, FA machinery, medical machinery, robotics, automated assembly lines, semiconductor manufacturing, assembly and textile machinery parts has been widely used and has shown the growing vitality.
AC servo motion control products in the development process, it is always the integration of advanced mechatronics and control theory. AC servo motion control products, mainly machinery supporting the application-based, mainly related to machine tools, food packaging, textile, electronics manufacturing, plastics machinery, printing paper, rubber machinery.
In the field of machine tools, AC servo motion control products are used features are:
(1) analyzed here, the AC servo motion control products include AC servo (1) high speed and precision. For high-speed high precision machine tool feed drive, there are "high-speed rotary precision ball screw servo motor plus" and "linear motor direct drive" types. The current use of high-speed ball screw-driven machine tool maximum speed of 90m/min, acceleration of 1.5g; use of high-speed high precision linear motor machine has reached the maximum rapid traverse 208m/min, acceleration of 2g, and there is room for development.
(2) multi-axis oriented. With the 5-axis CNC systems and programming software, the popularity of 5-axis control machining centers and CNC milling machine has become a development hot spot, especially in the processing of free Surfaces, to overcome the 3-axis control of the cutting speed Jiejin O'clock cutting to zero defects. Controllers, AC servo motors, and servo control platform-specific detection devices, these products form a complete servo motion control products, as shown in Figure 1.
2, food packaging.
With the rapid development of China's market economy and improve people's quality of life, consumers are expected microwave food, snack foods and convenience foods such as frozen food demand will increase, which will lead directly related to food packaging needs. China is expected food and packaging machinery industry for a long time in the future will remain positive growth. Thus, countries in the "Eleventh Five-Year Plan" clearly pointed out to narrow the gap between supply and demand, so that the food industry to catch up with the world advanced level, and provide advanced technical equipment. This must require domestic food and packaging machinery more than 18% annual growth rate of new product output value reached 25%.
Applications in food packaging products, AC servo motion control have the following characteristics:
(1) mechanical structure greatly simplified. Traditional packaging machinery control system to use more relays, contactors, control circuit, the complexity increases as the executing agency and the increase in adjusted positions to increase, making the machine more and more complicated to manufacture, adjust, use and maintenance are inconvenient. The AC servo motion control product application, available computer, sensor technology, the new servo technology to replace bulky electrical control cabinet and drive unit, so that the sharp decline in the number of components, structure, greatly simplified, the volume also will be reduced.
(2) product quality. The more parameters to adjust some more, the superiority of AC servo motion control greater, which is the normal control mode can not be compared. Function increased to improve the reliability, flow servo motion control system to keep the original packaging machine in addition to the functions, but also gives many other features.
