【摘要】：随着多媒体投影机在家庭娱乐、科研教育、企事业单位等各行各业的广泛应用,对高亮度光源的要求也越来越高,超高压汞灯以其亮度高、寿命长、体积小和成本较低的优点,占据了投影机光源市场的95%以上。超高压汞灯生产过程中需要对电弧管进行封接,国内电弧管封接设备多以引进国外为主。本文在综合国内外生产工艺的基础上,研究了一种基于旋封方法和水冷冷却方式的超高压汞灯封接设备。根据超高压汞灯旋封工艺,设备中采用气缸完成上料、点火和夹持动作,使用三组伺服进给系统协同运动完成电弧管的封接。本文设计了旋封机的总体结构,并对伺服进给系统、火头旋转机构和水槽结构等关键机构进行分析与设计。本文选用以三菱FX3G系列可编程控制器为核心的控制系统,完成了控制系统总体结构设计。通过对控制系统中所使用元器件的选型和性能分析,并对控制系统硬件电路包括主控回路、输入输出回路、模拟量回路以及伺服控制回路等进行详细的设计,完成了控制系统硬件设计。根据旋封工艺流程编写PLC程序,使用触摸屏设计了人机界面,完成了对控制系统软件的设计。根据设备技术要求完成了对旋封机的结构、硬件、软件和总体调试,对调试和生产过程中出现的有关问题进行了分析,并提出了解决方案,完成了不合格产品的成因的分析,并提出了解决方法。
[Abstract]:With the wide application of multimedia projector in home entertainment, education, scientific research institutions and other industries, the high brightness light source are increasingly high requirements, the advantages of ultra high pressure mercury lamp with high brightness, long life, small volume and low cost, occupy more than 95% market projector light source. In the production process of UHV mercury lamp, it is necessary to seal the arc tube, and the domestic arc tube sealing equipment is mainly introduced abroad. On the basis of comprehensive production technology at home and abroad, a kind of ultra high pressure mercury lamp sealing equipment based on the sealing method and water cooling cooling method is studied in this paper. According to the sealing technology of the super high pressure mercury lamp, the cylinder is used to complete the charging, ignition and clamping actions. The three groups of servo feeding systems cooperate with each other to complete the sealing of the arc tube. This paper designed the overall structure of the rotating sealing machine, and analysis and design of the key mechanism of servo system and rotor rotating mechanism and tank structure. In this paper, the control system based on the MITSUBISHI FX3G series programmable controller is selected, and the overall structure design of the control system is completed. Through the selection and performance analysis of the components used in the control system, and the detailed design of the hardware circuit of the control system, including the main control loop, the input and output circuit, the analog loop and the servo control circuit, the hardware design of the control system is completed. The PLC program is compiled according to the technological process of the rotary seal, and the man-machine interface is designed by the touch screen, and the design of the control system software is completed. According to the technical requirements of the equipment, we completed the structure, hardware, software and overall debugging of the rotary seal machine, analyzed the problems occurred in the commissioning and production process, and put forward the solutions, completed the analysis of the causes of the unqualified products, and put forward the solutions.
