摘　　要：体温计生产中毛细管直径及水银玻璃包的容积存在一定误差,造成了各体温计刻度线位置和间隔不同;目前对体温计区别不同的分号生产仍采用工人手工方式,效率低,劳动强度大;通过对水银体温计分号方式设计及其设备开发,设计了以可编程控制器(PLC)为基础的控制系统,给出了PLC的硬件和软件流程图的设计方法,应用该技术研制的分号机,自动化程度明显提高,且有效减少了产品误差,带来了较好的经济效益。There is certain deviation between the capillary diameter and the volume of mercury glass bulb in thermometer production , which lead to the differece of thermometer scale location and spacing . The making of classified thermometer is still using manual mode, which is in low efficiency and high labor intensity . Through the design of mercury thermometer classification method and the development of its equipment, the classified thermometer control system based on PLC is developed in this article , which give the design methods of PLC hardware and flow process chart. The classification thermometer made by this technology significantly improves automatic process, effectively reduces production error and obtains good economic benefit.
