目的借助虚拟现实技术对J2205北人对开双色胶印机定位装置进行改装。方法首先对J2205进行实地考察,确定改装方案,并对其结构进行划分,然后利用SolidWorks作为建模工具建立胶印机数字化模型,VRML虚拟现实建模语言作为输出交互工具发布到网页上,并验证改装后的J2205性能。结果结合无侧规技术成功实现了胶印机的虚拟改装,改装后的J2205节约了25%的纸张轴向定位时间,定位更加准确,能够提高套印精度。结论 J2205胶印机虚拟定位装置的改装能够对印刷机进行反复改装,降低了生产成本,并可利用传感器进行定位,充分发挥其智能作用。

Objective To modify the positioning device for the J2205 double-color folio offset printer with the help of virtual reality. Methods First the J2205 offset printer was investigated on the spot, then the modification methods were determined and finally its structure was partitioned. SolidWorks was then used as the modeling tool to set up digital model for the offset printer, and the virtual reality modeling language VRML was employed as the interactive tool to output model on webpage. And the properties of the modified J2205 were verified. Results The results showed that virtual modification of offset printer was a- chieved in combination with non-lateral guide technology, and the modified J2205 saved 25% axial positioning time. It improved the accuracy of positioning and overprinting. Conclusion The virtual positioning device of J2205 could be modified repeatedly, which reduced the production cost. The position sensor could be used to help the full performance of the intelligent machine.
