【摘要】：随着中国经济的高速发展，生产企业逐步采用喷码机替代人工喷印，以提高生产效率和产品质量，满足大规模生产的要求，市场对喷码机的需求越来越大。但与不断扩大的喷码机需求局面相比，喷码机的发展相对滞后，，国内主要依赖进口满足对喷码机的需求。开发更多适合我国实际生产需要和拥有自主知识产权的喷码机，对我国喷印技术的发展有着十分重要的意义。本论文正是以此为背景，提出了一套大字符喷码机的设计方案。本论文首先介绍了喷码机的国内外发展状况和未来发展趋势，总结出课题研究的目的和意义，从而确定了本论文主要的研究工作。在此基础上，结合大字符喷码机项目的技术要求，阐述了大字符喷码机控制系统的总体设计方案，将系统按功能分为电源、人机交互、喷码控制、清洗控制和油墨压力控制五个模块，概述了每个模块的作用与功能。在完成系统的总体设计之后，本文详细介绍了主控制器、触摸屏、编码器、光电传感器和压力传感器的选型，并完成了主控制器最小系统、电源模块、墨水清洗液切换控制模块、气泵控制模块、压力传感器输入模块、喷头驱动模块、按键连接、指示灯连接、RS232接口、SD卡接口、触摸屏接口、JTAG接口、编码器输入接口、光电开关接口的电路设计，给出了人机交互模块、喷码控制模块、按键操作处理和指示灯控制模块、油墨压力控制模块以及待机定时清洗模块详细的软件设计流程。最后，完成了整个大字符喷码机系统的调试。本论文设计的大字符喷码机具有人性化的、符合中国人习惯的操作界面，操作简单易掌握，功能丰富，喷印速度快，满足了用户的需要。
[Abstract]:With the rapid development of Chinese economy, the production enterprises gradually adopt the inkjet printer instead of manual printing to improve the production efficiency and product quality, meet the requirements of large-scale production, and the market demand for the inkjet printer is increasing. However, compared with the expanding demand of inkjet, the development of inkjet is relatively lagging behind, and domestic mainly depends on imports to meet the demand for inkjet. It is of great significance for the development of jet printing technology in China to develop more inkjet printer which is suitable for the actual production needs of our country and has its own intellectual property rights. Based on this background, this paper puts forward a design scheme of large character inkjet printer. This paper first introduces the domestic and international development situation and the future development trend of the inkjet code machine, summarizes the purpose and significance of the research, and determines the main research work of this paper. On this basis, combined with the technical requirements of the large character inkjet printer, the overall design scheme of the control system of the large character inkjet code printer is expounded. The system is divided into power supply, man-machine interaction and inkjet code control according to its function. Cleaning control and ink pressure control five modules, outlined the role and function of each module. After the overall design of the system is completed, the selection of the main controller, touch screen, encoder, photoelectric sensor and pressure sensor is introduced in detail, and the minimum system of the main controller and the power module are completed. Ink cleaning fluid switch control module, air pump control module, pressure sensor input module, nozzle drive module, key connection, indicator lamp connection RS232 interface SD card interface, touch screen interface JTAG interface, encoder input interface, The circuit design of optoelectronic switch interface is given. The detailed software design flow of man-machine interaction module, spray code control module, key operation processing and indicator lamp control module, ink pressure control module and standby timing cleaning module are given. Finally, the debugging of the whole large character inkjet printer system is completed. The large character inkjet printer designed in this paper has humanized and Chinese custom operation interface, simple and easy to master, rich function, fast printing speed, and meets the needs of users.
