摘要
硅片下料机是光伏电池制绒、刻蚀工艺段的自动化设备,升降单元是其核心部件,用来实现硅片在自动传输过程中的换向与传输。在现场使用过程中发现,由于原有单元布局局限性和结构不合理,升降过程持续偏心,从而导致硅片传输偏移传输方向,进而出现设备卡片、碎片等故障。通过对现有单元结构受力分析、增加弹簧导向机构和限位机构,多次实验调试后该单元在稳定性上得到很大提升。目前客户现场大量使用验证,改进后的升降单元稳定可靠,满足生产和使用要求,得到客户认可。
The silicon unloading machine is a kind of automation equipment for the manufacture and the etching process of the photovohaic cell. The lifting unit is the core part of the silicon chip, which is used to realize the transfer and transmission of the silicon wafer in the process of automatic transmission. In the using process at the site, it is found that due to the limitations of the cell layout and unreasonable structure, the lifting process is continuously eccentric to result in wafer offset transmission direction, and the problems of equipment cards, debris and other fault are occurred. Through the analysis on the existing unit structure and increasing the spring guide mechanism and the limiting mechanism, the stability of the unit has been greatly improved after several experiments. At present, with the on-site verification by a large number of customers, the improved lifting unit is stable and reliable and can meet the production and use requirements.
