摘  要

本设计为点胶机设计—悬臂式结构，末端执行器是一个固定在Z轴上的点胶头， X、Y、Z三个方向上都是由步进电机带动滚珠丝杠，将电机轴的旋转运动转化成工作平台的直线运动，实现了点胶机在规定工作范围内各个点的点胶、涂胶工作。在PLC控制下，该结构能按照程序自动在相应的点完成点胶、在一段距离内完成涂胶工作，也可由手动控制到达工作范围内的各个点以及完成回零工作。选用的步进电机用电脉冲信号进行控制，将电脉冲信号的个数和频率分别转化成为末端执行器的位移和移动速度。

ABSTRACT

This design for glue machine design-the cantilevered structure, end actuator is a fixed in the Z axis at a point on the rubber head, X, Y, Z three direction is by stepping motor drive the ball screw, will the motor shaft rotation movement into working platform linear motion, realize a little gum machine in the provisions within the scope of work of various points point glue, glue work. In the PLC control, this structure can be in accordance with the procedures in the corresponding points finish glue, in a distance work to finish glue, can also be made by manual control to work within the scope of the various points, and complete back to zero. The selection of stepping motor power pulse signal control, the electrical impulses of the number and frequency signal into a respectively at the end of the implementation of the displacement and speed.

Key words: Glue machine, cantilevered, step motor, the ball screw, PLC
