置来完成货物产品的传送和装卸大大节约了劳动力，在现代工业中的使用率越来越频繁。而机械手的自动化实现有很多方式，PLC控制就是其中的一种。PLC是一种以微处理器为核心的工控装置它采用可以编程的存储器，用来在其内部存储执行逻辑、顺序、计时、计数和算数运算等操作的指令，并能通过数字、模拟的输入输出控制各类设备的运行。本设计的机械手所涉及到的运动过程，将通过对PLC软件编程驱动机械手上的步进电机运动，经过不断地编程调试使其能完成上升、下降，左右移动，加紧和放松物件的运动。

关键词：机械手；PLC；步进电机

Abstract

With the continuous development of automation technology, realizes the automatic control of most of machinery and equipment, machinery industry is the one hand appeared,it replaces some work in harsh environment, high intensity,

and even life-threatening workers; and because the can in accordance with certain procedures, time and location to complete the transfer and loading and unloading of goods product greatly saves labor in the modern industry in the use of more and more frequently.Automatic mechanical hand has many ways, a PLC control is one of the.PLC is a kind of industrial control device with microprocessor as the core of the memory can be programmed, used to implement logic, sequence, timing, counting and arithmetic operation in its internal storage instructions, and through digital, analog input and output of the control of various types of equipment operation.The design of the robot motion process involved, will be through the PLC software programming to drive the manipulator on the stepper motor, through continuous programming and debugging, so that it can complete the rise, decline, and move around, stepping up and relax the object motion.

Key Words:Machine hand;PLC;Stepper motor
