摘要

自动点胶机是由 X 轴左右方向上、Y 轴前后方向上和 Z 轴上下方向上构成的机构。自动点胶机末端的执行机构是分配头或多点胶头，可实现 3d、4d 模式的点胶，即在产品表层、外部轮廓、垂直的平面、球形以及曲面部位进行快捷打点、绘画线段、绘画圆及各种形状不规则图形。精确定位，精准控胶，不拉丝，不漏胶，不滴胶。每个方向上都有一个步进电机和滚珠丝杠，通过滚珠丝杠可以将电机中的旋转运动变为整个机构所需的直线运动。这种结构选择 PCLS 可编程控制器来控制整个组织的运动，控制程序发送电信号来控制电机，步进电机将信号进入分配头位移和移动速度。同时，通过全身整修，也可以自动点胶机进行手动控制，每个点在工作平台的范围内进行分配任务。

ABSTRACT

Automatic dispensing machine throughout the main body has three movement direction, that is, X, Y, Z direction, are left and right, front and back, up and down the three directions. The actuator automatic dispensing machine is ultimately a dispensing head or a dispensing head, which can realize three-dimensional, four-dimensional path dispensing, available on the product surface, outer wall, vertical surface, spherical surface gap, fast RBI, painting line, round and irregular graphics. Precise positioning, precise control of glue, not drawing, no leakage, no glue. Each direction has a stepper motor and ball screw, through the ball screw can turn the motor into a whole body of the linear motion. The structure uses the PCL programmable controller to control the motion of the whole mechanism, and the control program sends the electric pulse signal to control the motor. At the same time, through the overall transformation of the body a little, you can also turn the automatic dispensing machine to manual control to work within the scope of the platform to complete the task of each point.
