【摘要】：随着手机、平板、电脑、液晶电视等领域的发展,国内对液晶玻璃基板的需求迅速增长。在玻璃基板的生产制造中,高效率和高良品率越来越成为制造工艺过程的关键。然而国内市场所需液晶玻璃基板主要依赖进口,为保障产业安全,大力发展对玻璃面板的自动化生产和设备研究是改善中国光电产业生态状况、完善产业链的重要措施之。基于上述背景,本课题依托东德集团实际项目需求,开发一套液晶玻璃基板生产线控制系统和旋转台设备的设计,能够一天24小时稳定可靠工作,实现液晶玻璃基板的自动化缓存、检查、包装。本文的主要研究对象包括两部分,第一部分是针对液晶玻璃基板生产线各工艺段设备的控制要求以及人机交互界面友好的要求,开发设计出一套完整实用的控制系统,以保证生产线的效率和安全性;第二部分是旋转台设备的设计,设计要求将玻璃基板旋转180°,以完成包装需求。第一部分是基于PLC的液晶玻璃基板的加工生产线控制系统设计,以三菱Q系列PLC作为生产线的核心控制设备,其可靠性高,编程简单,采用CC-LINK现场总线技术,对各设备进行模块化控制,减少了控制线路的长度,提高了通讯效率从而减少故障率;进行了硬件部分(包括PLC模块、外围装置、触摸屏)的选型、I/O地址分配以及软件部分的设计(通过三菱编程软件GX Developer进行了 PLC控制程序的梯形图编程);以三菱GT 1595触摸屏作为生产线的人机交互界面,保证整个生产线中设备的安全稳定高效的运行;最后进行了软件和硬件设计的模拟调试和现场调试,对设计的控制系统进行了验证。第二部分是旋转台设备的设计,根据旋转台的功能要求与设计准则,对旋转台设备进行了设计,主要包含了驱动部分和旋转部分、机架部分,驱动部分首先阐述了伺服电机的原理,选型方法以及对交流伺服电机参数进行详细的理论计算;旋转部分包含了气缸的选择和理论计算以及旋转轴的设计和强度分析和对轴承的选择与校核,最后根据驱动和旋转两部分的设计进行了机架部分的设计。生产线控制系统的设计进行了系统的模拟调试,旋转台设备经过本文的理论计算以及现场安装调试和试运行效果,验证了系统投入使用情况,均达到了设计预期效果。
[Abstract]:With the development of mobile phone, tablet, computer, LCD TV and so on, the domestic demand for LCD glass substrate is increasing rapidly. However, the domestic market mainly depends on the import of liquid crystal glass substrate. In order to ensure the industrial safety, it is an important measure to improve the ecological condition of China's optoelectronic industry and perfect the industrial chain to develop the automatic production of glass panel and the research of equipment. Based on the above background, based on the actual project requirements of East Germany Group, this project develops a set of liquid crystal glass substrate production line control system and rotary table equipment design, which can work steadily and reliably 24 hours a day. Realize the automatic buffer, inspection and packaging of liquid crystal glass substrate. The main research object of this paper includes two parts. The first part is to develop and design a set of complete and practical control system according to the control requirements of each process section of liquid crystal glass substrate production line and the requirement of friendly man-machine interface. In order to ensure the efficiency and safety of the production line, the second part is the design of the rotary table equipment, which requires the glass substrate to rotate 180 掳to complete the packaging requirements. The first part is the design of the production line control system of liquid crystal glass substrate based on PLC. With Mitsubishi Q series PLC as the core control equipment of the production line, its reliability is high, the programming is simple, and the CC-LINK fieldbus technology is adopted. The modularization control of each equipment reduces the length of the control circuit, improves the communication efficiency and reduces the failure rate, and carries on the hardware part (including PLC module, peripheral device, etc.) The selection of touch screen and the design of software part (using Mitsubishi programming software GX Developer to program ladder diagram of PLC control program), taking Mitsubishi GT 1595 touch screen as man-machine interface of production line, Finally, the simulation debugging and field debugging of software and hardware design are carried out, and the designed control system is verified. The second part is the design of the rotating table equipment. According to the function requirements and design criteria of the rotary table, the rotary table equipment is designed, which mainly includes the driving part, the rotating part, the frame part. In the driving part, the principle of the servo motor, the selection method and the detailed theoretical calculation of the parameters of the AC servo motor are introduced. The rotation part includes the selection and theoretical calculation of the cylinder, the design and strength analysis of the rotary shaft and the selection and verification of the bearing. Finally, the frame part is designed according to the design of the driving and rotating parts. The design of the production line control system is simulated and debugged, and the rotary table equipment is verified by the theoretical calculation, field installation, debugging and trial operation, and the expected design effect is achieved.
