摘　　要：针对传统QFP(四边引线扁平封装电路)分离模具的驱动系统结构复杂、价格昂贵、体积大的缺点,通过采用一套伺服电机驱动一对凸轮的方式来代替原来的两套伺服系统驱动机构。介绍了分离模具的结构,阐述如何从时序分析开始到利用Pro/e软件自动生成凸轮轮廓曲线的设计过程。通过样机试验表明,该机构不但降低了成本,而且更紧凑,运行也更加稳定可靠。Aiming at the disadvantages of complex structure,high price and large volume of the drive system of the traditional QFP(Quad Flat Packages)singulation die set,By using a set of servo motor to drive a pair of cams to replace the two sets of servo system.Introduces the structure of the singulation die set,and expounds the design process from the time sequence analysis to the automatic generation of cam profile curve by using Pro/E software.The prototype test shows that the mechanism not only reduces the cost,but also is more compact,stable and reliable.
