【摘要】： 随着社会的发展,人们对大型户外广告的需求越来越大。广告业的迅猛发展随之带动了宽幅喷墨打印机产业的快速发展。本论文结合宽幅数字喷墨打印机的研制项目,重点研究与设计了宽幅数字喷墨打印机的结构组成、电机运动控制以及喷头系统设计。最终设计完成了一台高性能的宽幅数字打印机。具体任务如下: ①研究与设计了宽幅数字喷墨打印机的机械机构、运动控制系统。分析了宽幅喷墨打印机的工作原理及工作流程,从中解决了设计的关键技术及难点。 ②分析了字车无刷直流电机工作原理、运动控制曲线。同时对无刷直流电机进行了数学建模及基于DSP的MATLAB仿真,观察其运动曲线,并选用了改进性的S型曲线,使字车能够平稳、快速、精确的运行。其次对走纸电机进行软硬件控制设计,并进行了相关的实验,最终选用16细分。 ③研究喷头的工作原理,完成喷头系统的设计,包括安装方式设计、供墨装置和温度补偿装置设计。并分析了在不同绘图模式下的打印原理,字车和走纸步进电机具体运动方式,及在该方式下走纸步进电机需要步进的距离。 ④整机安装与测试。进行字车回原点、平稳性检测,并修改相应参数进行打印实验比较。从实验可以得出:该打印机打印宽度达3.2m,分辨率720DPI,草绘输出速度达到180 m2/h,且输出质量较高。
[Abstract]:With the development of society, the demand for large-scale outdoor advertising is increasing. The rapid development of advertising industry has led to the rapid development of wide-width inkjet printer industry. In this paper, the structure, motor motion control and nozzle system design of wide-width digital inkjet printer are studied and designed in combination with the research project of wide-width digital inkjet printer. Finally, a high performance wide digital printer is designed. The main tasks are as follows: 1 the mechanical mechanism and motion control system of wide-width digital inkjet printer are studied and designed. The working principle and working flow of wide-width inkjet printer are analyzed, from which the key technology and difficulty of design are solved. 2 the working principle and motion control curve of brushless DC motor are analyzed. At the same time, the mathematical modeling of brushless DC motor and MATLAB simulation based on DSP are carried out, and the motion curve is observed, and the improved S-shape curve is selected to make the car run smoothly, quickly and accurately. Secondly, the hardware and software control design of the paper moving motor is carried out, and the related experiments are carried out. Finally, 16 subdivision is selected to study the working principle of the nozzle, and to complete the design of the sprinkler system, including the design of the installation mode. Ink supply device and temperature compensation device design. The principle of printing in different drawing modes, the specific movement mode of the car and paper stepping motor, and the distance required for the stepping motor in this mode are analyzed. 4 the installation and testing of the whole machine. Carry on the word car to return the origin point, check the stability, and modify the corresponding parameters to print the experiment comparison. The experimental results show that the printer has a print width of 3.2 m, a resolution of 720DPI, a sketch output speed of 180 m2 / h and a high output quality.
