一种新型印刷、烘干和贴膜一体机的研究
摘要
目前我国电视机,显示器等产品面板的加工是先注塑之后贴上保鲜膜,以保护好面板的高光面,然后再送到组装车间印刷LOGO,烘干和贴保护膜。这一过程虽然是由流水线完成,但需要大量的工人配合协作,人力成本很高。而且由于是人工操作,所以一致性不如自动化的好。
本文研究了一种集印刷、烘干和贴膜一体的一种新型的设备。利用该设备,面板从注塑机出来之后可以直接加工入库,而无须进入组装车间。这样可以节省大量的时间和人力成本,提高生产效率。文中对印刷的方式进行了选择,分别研究了丝网印和移印的优缺点。对烘干过程进行了仿真分析,研究了烘干过程中面板表面的温度分布,并与实验结果进行了对比。对贴膜机的膜在工作过程中会过度拉伸以及卷到滚轮上的问题进行了研究,找到了原因并提出了解决方法。通过实验证实了这些解决方法可以很好的解决问题。
研究结果表明,本文所述的印刷、烘干和贴膜一体机能很好的实现自动化的工作,能够节省大量的人力成本,并能提高生产效率。所做的仿真分析也都由实验所证实。本文的研究成果对于很多设备面板的印刷和贴膜加工有重要的指导意义。
Nowadays the panels of many Chinese products, such as televisions and monitors, are produced by injection molding. After that, the panels are covered with plastic wrap to protect the high-gloss surface. Then they are sent to the assembly plant to print LOGO on the panels. And then dry the LOGO and sticking films on the panel. Although this working procedure is completed by the assembly line, a lot of workers are needed and the labor costs are high. And as it is manually operated, the consistency is not as good as the automation.
In this paper, a new integrated printing, drying and sticking films’machine is studied. With this equipment, the panels can be directly processed and put into storage after injection molding, without being sent to the assembly plant. In this way, a lot of time and labor costs are saved, and the production efficiency are also improved. In this paper, the printing method is chosen. The advantages and disadvantages of screen printing and pad printing are studied respectively. The drying process is analyzed by simulation software to see the distribution of the temperature on the panel, and the results are compared with the experimental data. The problems that the films are over stretched and the films will sometimes be brought to the rollers are studied, and both the reasons and the ways to solve them are found. The experiments prove that these methods can solve these problems.
The research shows that the new integrated printing, drying and sticking films’machine can realize automation and save a lot of labor costs, together with improving the productivity. The simulations are all proved by the experiments. The results of this paper have important significance to the processing of the panels of many devices in printing and sticking films.
