【摘要】：本论文对FESTO柔性加工系统进行了研究,在掌握设备主要结构和工作原理的基础上,提出了柔性加工系统的工作方案；根据生产线的工作方案,完成柔性加工系统的安装、调试等工作；针对本课题实际情况完成系统的整体及单元控制程序设计工作。本论文研究的主要方面包括： 1.提出了柔性加工系统的安装及控制方案。该生产线采用模块化设计,各工作单元都有相对独立的控制器,由S7-300PLC、LOGO、SPC200等控制器完成控制,实现产品的加工、物流、分检、装配等功能。 2.将气伺服立体仓库设计为柔性加工系统的毛坯库及传送站,实现该单元的“一站两用”功能。该工作单元由SPC200控制器进行控制,应用模块化编程思路保证程序的高效、稳定。 3.完成机械手工作流程的设计。机械手一方面完成工件的搬运、装火,另一方面完成对数控机床开、关门的控制,以减少中央控制器的工作程序。在程序设计时机械手的每个动作对应一个子程序,保证程序效率及机械手工作的可靠性。 4.以S7-300PLC为中央控制器,完成对整个柔性加工系统的控制。中央控制器的主要任务为收集各工作单元的信号,同时根据不同的信号输出不同命令。中央控制器的控制内容包括：生产线工作流程、伺服电轴位置控制、电轴使能开关控制、电轴极限位控制、系统停止和机械手手抓控制。通过对课题的研究,提出了一些较为实用的控制力方案和编程方法。该生产线在《柔性加工技术》课程中的应用证明,有利于学生在实际工作中掌握机械、气动、PLC控制和传感器技术,为学生的职业素质和创新能力培养提供了一个良好的实践平台。
[Abstract]:On the basis of mastering the main structure and working principle of the equipment, the work scheme of the flexible machining system is put forward, and the installation of the flexible machining system is completed according to the work plan of the production line. Debugging and other work; the actual situation of the system to complete the overall and unit control program design. The main aspects of this thesis include: 1. The installation and control scheme of flexible machining system are put forward. The production line adopts modular design, each working unit has relatively independent controller, which is controlled by S7-300 PLCU LOGOG SPC200 controller to realize the functions of product processing, logistics, inspection, assembly and so on. 2. The air servo stereoscopic warehouse is designed as the blank storehouse and transmission station of the flexible machining system, and the "one station" function of the unit is realized. The work unit is controlled by SPC200 controller, and the modularization programming method is used to ensure the high efficiency and stability of the program. 3. Complete the design of manipulator workflow. On the one hand, the manipulator completes the handling, loading and firing of the workpiece, on the other hand, it completes the control of the opening and closing of the CNC machine tool to reduce the working procedure of the central controller. In program design, each action of manipulator corresponds to a subroutine to ensure the efficiency of the program and the reliability of the manipulator. 4. S7-300PLC is used as the central controller to control the whole flexible machining system. The main task of the central controller is to collect the signals of each work unit and output different commands according to different signals. The control contents of the central controller include: the work flow of the production line, the position control of the servo electric axis, the electric axis enable switch control, the limit position control of the electric shaft, the system stop and the manipulator grasp control. Through the research of the subject, some practical control schemes and programming methods are put forward. The application of this production line in the course of flexible Machining Technology proves that it is beneficial for students to master mechanical, pneumatic PLC control and sensor technology in practical work. It provides a good practical platform for the cultivation of students' professional quality and innovative ability.
