英国一家柴油机制造商已安装了一台激光自动标记机,它能把条形码标在一排零件上,谢菲尔德Edward Pryor and Son有限公司曾为Cummins发动机公司Darlington工厂制试这种系统。这种标记系统将一种Unimation’s Puma 550五轴机器人和一台50W Nd:YAG激光器相结合。系统的其他部件包括一台条形码扫瞄器和将零件托盘送到标记机的传送带。当托盘接近标记时,扫瞄器读出其表面的条形码,这种代码表示托盘内零件的类型,机器人根据此信息可决定是按预先编好的程序移动还是对所装的货物打上记号。
A British automaker has installed a laser auto-marker that marks bar codes on a row of parts, and Sheffield Edward Pryor and Son Ltd. tested the system at Cummins Engine Company’s Darlington plant. This marking system combines an Unimation’s Puma 550 five-axis robot with a 50W Nd: YAG laser. Other parts of the system include a bar code scanner and a conveyor that feeds the parts tray to the marking machine. When the tray approaches the mark, the scanner reads out the bar code on the surface. This code indicates the type of part in the tray. Based on this information, the robot can decide whether to move the pre-programmed program or mark the loaded goods.
