| 目的 设计一种打印规则，在喷墨技术作为一种高效的生产工具被用于先进制造时提高其喷墨打印精度。方法 通过墨滴观测系统分析喷点火频率对喷射状态的影响；分析串扰对喷嘴间的影响，获得高频连续喷射参数，并用高精度打印平台对不同模式进行测试。表征方法包括传统的图像质量分析方法以及喷墨制造获得的导电网格的导电性能对比。结果 使用提出的打印规则，喷墨点火频率达到78 kHz，打印样张网点面积率误差小于1%，竖线粗糙度方差约等于3 μm2。宏观和微观的视觉效果得到提升，打印制作的柔性触摸屏网格线条均匀线宽约65 μm，导电性良好。结论 优化后的打印规则可以弱化残余振动和串扰对其他喷嘴的影响，在提升打印效率的同时提高打印精度和点火频率，有效地促进压电喷头在喷墨制造领域的应用。 |
| 英文摘要: |
| The work aims to design a kind of printing rules to improve the inkjet printing accuracy when the inkjet technology is used for advanced manufacturing as an efficient production tool. Through ink droplet observation system, the effect of inkjet ignition frequency on the injection state was analyzed. By analyzing the influence of crosstalk on the part between nozzles, the continuous high-frequency injection parameters were obtained. Meanwhile, the high-precision printing platforms were used to test different modes. Characterization methods included traditional image quality analysis method and conductivity comparison on conductive grid obtained through inkjet manufacturing. With the printing rules put forward, the inkjet ignition frequency was up to 78 kHz, the dot area coverage error of printing paper samples was less than 1% and the vertical line roughness variance was approximately equal to 3 μm2. The macroscopic and microscopic visual effects were improved. The uniform line of printed flexible touch screen grid line was about 65 μm wide with good electrical conductivity. The optimized printing rules can weaken the influence of the residual vibration and crosstalk on other nozzles. The printing accuracy and ignition frequency are enhanced while improving the printing efficiency, which effectively promotes the application of electric nozzle in the inkjet manufacturing field. |
