【摘要】：隨著彩色個(gè)性化三維物品在市場(chǎng)的需求增大,而傳統(tǒng)平面印刷技術(shù)中難以印刷具有復(fù)雜曲面特征的產(chǎn)品。人工曲面繪制方法存在效率低、人力成本高等問題;采用轉(zhuǎn)印方法需要制備印版,工藝復(fù)雜,存在污染。曲面噴墨打印是一種新型的噴墨打印技術(shù),以其快速、數(shù)字化和綠色制造等特征在曲面打印方面有著獨(dú)特優(yōu)勢(shì)。但是該技術(shù)應(yīng)用在實(shí)際中,仍有空間曲線運(yùn)動(dòng)控制、噴墨打印控制和噴墨材料等諸多問題有待解決。針對(duì)曲面噴墨打印過程中空間曲線運(yùn)動(dòng)難以實(shí)現(xiàn)的難題,本文通過設(shè)計(jì)曲線運(yùn)動(dòng)方式開發(fā)了基于PMAC的多軸運(yùn)動(dòng)控制系統(tǒng),實(shí)現(xiàn)了對(duì)步進(jìn)電機(jī)與噴墨裝置的同步控制,開發(fā)了運(yùn)動(dòng)系統(tǒng)軟件控制數(shù)據(jù),并通過曲面噴墨打印試驗(yàn)驗(yàn)證了運(yùn)動(dòng)控制系統(tǒng)的可行性和有效性,主要內(nèi)容如下:1.運(yùn)動(dòng)控制系統(tǒng)設(shè)計(jì)。根據(jù)承印物表面噴墨的運(yùn)動(dòng)要求,設(shè)計(jì)了滿足承印平臺(tái)空間曲線運(yùn)動(dòng)的運(yùn)動(dòng)方式,搭建了曲面噴墨運(yùn)動(dòng)控制系統(tǒng)的試驗(yàn)平臺(tái);采用IPC+PMAC的運(yùn)動(dòng)控制系統(tǒng)形式,實(shí)現(xiàn)了承印平臺(tái)多軸運(yùn)動(dòng)和噴墨控制功能。2.運(yùn)動(dòng)控制系統(tǒng)硬件的實(shí)現(xiàn)。根據(jù)PMAC運(yùn)動(dòng)控制系統(tǒng)硬件架構(gòu),對(duì)Clipper運(yùn)動(dòng)控制器和ACC-34AT擴(kuò)展卡、DTC-8B端子板進(jìn)行與步進(jìn)電機(jī)驅(qū)動(dòng)器以及步進(jìn)電機(jī)的連線;3.噴墨運(yùn)動(dòng)過程中的關(guān)鍵技術(shù)研究。根據(jù)曲面噴墨運(yùn)動(dòng)過程中噴墨位置補(bǔ)償,承印臺(tái)運(yùn)動(dòng)速度與加速度控制的要求,對(duì)關(guān)鍵技術(shù)進(jìn)行研究,并根據(jù)PMAC的編程規(guī)則對(duì)運(yùn)動(dòng)程序進(jìn)行了設(shè)計(jì)和編寫。4.曲面噴墨打印試驗(yàn)研究。為了驗(yàn)證系統(tǒng)的功能,采用圓柱體作為承印物,進(jìn)行了噴墨打印試驗(yàn)驗(yàn)證。實(shí)驗(yàn)結(jié)果表明,本文開發(fā)的基于PMAC的多軸運(yùn)動(dòng)運(yùn)動(dòng)控制系統(tǒng)能夠滿足曲面噴墨打印的空間曲線運(yùn)動(dòng)要求,為后續(xù)進(jìn)一步深入研究曲面噴墨打印奠定了基礎(chǔ)。
[Abstract]:With the increasing demand of color personalized 3D products in the market, it is difficult to print the products with complex surface features in the traditional graphic printing technology. The artificial surface rendering method has some problems, such as low efficiency and high labor cost. Curved surface ink-jet printing is a new inkjet printing technology. It has a unique advantage in curved surface printing because of its rapid, digital and green manufacturing characteristics. However, in practice, there are still many problems to be solved, such as space curve motion control, inkjet printing control and inkjet materials. In view of the difficult problem of space curve motion in curved surface inkjet printing, a multi-axis motion control system based on PMAC is developed by designing curve motion mode, which realizes synchronous control of step motor and inkjet device. The software control data of motion system are developed, and the feasibility and effectiveness of motion control system are verified by surface inkjet printing test. The main contents are as follows: 1. Motion control system design. According to the motion requirement of ink jet on substrate surface, the motion mode of space curve motion of substrate is designed, and the test platform of surface ink jet motion control system is built, which adopts the form of IPC PMAC motion control system. Multi-axis motion and ink jet control function. 2. Hardware implementation of motion control system. According to the hardware architecture of the PMAC motion control system, the Clipper motion controller and the ACC-34AT extension card DTC-8B terminal board are connected with the stepper motor driver and step motor. Research on key techniques in Inkjet Motion. According to the requirements of the compensation of ink-jet position in the process of curved surface ink-jet motion and the control of the speed and acceleration of the printing platform, the key technology is studied, and the motion program is designed and written according to the programming rules of PMAC. Experimental study on Surface Ink-jet Printing. In order to verify the function of the system, the ink jet printing test was carried out using the cylinder as the substrate. The experimental results show that the multi-axis motion control system based on PMAC developed in this paper can meet the spatial curve motion requirements of curved surface inkjet printing, which lays a foundation for further research on curved surface inkjet printing.
