This paper investigates the application of XINJE PLC in the control system of automatic bicomponent epoxy adhesives glue machine with a stepping motor of many pulses output drive According to the. design requirements of its automatic mixing ratio, plastic speed control and glue control, using XINJE PLC as control er, the floating point arithmetic is used to calculate the exact num-ber of drive pulses. Two gear metering pumps driven by the stepper motor are used to mix. This mixing glue machine with high effi-ciency can meet the needs of production.%探讨信捷PLC在自动灌胶机控制系统中多轴脉冲输出驱动步进电机的应用。针对自动灌胶机要求混合比例正确，出胶速度可控，胶量可控的设计要求，采用信捷PLC作为控制器，运用浮点数运算，计算出精确的驱动脉冲数。由步进电机驱动两台齿轮计量泵，进行混合。系统出胶量大，能满足生产的需求。
