【摘要】：生产线喷码机在制造、加工、包装工业生产中充当着重要一个角色，在批量、外形不规则的产品中的外包装生产中发挥着重要的作用。目前的喷码打印机存在功能单一，喷印质量不高，可靠性低，维护成本高等问题，很大程度上限制了产品多样化、多元化方向的发展。此外，效率的低下，以及假冒伪劣产品的出现，也把对高性能、更高用户体验的喷码机的需求提上了日程。针对以上问题，本文结合嵌入式技术，开展了通用性较强的生产线喷码打印系统的研究，并结合嵌入式平台的可延展性，设计了一种可靠性强、精度高的喷码打印系统。本文首先介绍了生产线喷码打印机国内外的研究现状和发展趋势，分析了我国在喷码打印行业存在的一些问题和弊端，提出了对新型喷码打印系统的具体需求。针对需求分析，结合嵌入式技术，提出了高性能、高精度的喷码打印机硬件系统的设计思路。然后根据平台化设计的思想，采用主板和接口扩展板的组合模式实现嵌入式的喷码打印硬件平台化设计，并根据包装行业的实际需求，依据平台化设计思路，划分系统硬件功能模块，搭建系统平台。接着围绕MIPS构架下的嵌入式处理器AU1250进行主板硬件平台设计，详细阐述包括中央处理器模块，存储模块，上下位机通讯模块和墨路系统模块等核心组件的设计，并针对具有普遍意义的喷码打印功能需求，进行扩展板上的设计，以及信号输入输出模块的设计，系统内外部信号的监测和检测模块设计等等。最后分析阐述硬件设计中的信号完整性、EMC等问题，提出了解决方案，，保证了系统的可靠性，并描述了喷码打印机功能和性能测试的结果。
[Abstract]:The production line inkjet printer plays an important role in manufacturing, processing and packaging industry, and plays an important role in the outer packaging production of batch and irregular products. At present, the problems of single function, low quality, low reliability and high maintenance cost limit the development of product diversification and diversification. In addition, inefficiency and the emergence of fake products also put the demand for high performance, higher user experience inkjet printer on the agenda. In view of the above problems, this paper combines the embedded technology, carries out the research of the production line spray code printing system with strong generality, and combines the extensibility of the embedded platform, designs a kind of high reliability and high precision inkjet code printing system. This paper first introduces the research status and development trend of the production line inkjet code printer at home and abroad, analyzes some problems and disadvantages existing in our country's inkjet code printing industry, and puts forward the specific requirements for the new type of inkjet code printing system. According to the requirement analysis and the embedded technology, the design idea of the high performance and high precision hardware system of the printer is put forward. Then, according to the thought of platform design and the combination mode of main board and interface extension board, the embedded design of spray code printing hardware platform is realized, and according to the actual demand of packaging industry, according to the thought of platform design, Partition the system hardware function module, build the system platform. Then the main board hardware platform is designed around the embedded processor AU1250 under the MIPS framework. The design of the core components including the central processor module, the storage module, the communication module of the upper and lower computer and the ink path system module are described in detail. In order to meet the requirements of the general function of inkjet code printing, the design of the expansion board, the design of the signal input and output module, the monitoring and detection module of the internal and external signals of the system, and so on, are carried out. Finally, the problems of signal integrity and EMC in hardware design are analyzed, and a solution is proposed to ensure the reliability of the system. The test results of the function and performance of the printer are described.
