注塑机械手单片机系统设计

Design of Single Chip Microcomputer System for Injection Molding Machine Manipulator

主要以注塑机机械手的控制系统展开论述,完成了硬件电路设计及软件设计,包括输入输出模块,步进电机控制,单片机的选型,各驱动模块的选择等。采用单片机作为CPU(Central Processing Unit)的注塑机械手控制系统。针对不同模块,采用相应的电路设计。主要介绍主控制部分的电路设计,机械手采用双自由度,由28BYJ-48的步进电机作执行元件,步进电机采用ULN2003芯片驱动模块,控制器方面采用AT89C52单片机以及复位电路、晶振电路的设计整合,键盘输入采用4×4简易矩阵键盘,显示屏采用数码管显示,由PS7219芯片驱动,最后通过整体硬件电路图进行仿真模拟。该机械手在保证其原有性能的前提下,使其性价比、体积、结构、价格和外形等均有所改善,设计出的各调整环节,很大程度上提高了人们对工具的使用便捷性。

This paper mainly focus on the injection molding machine manipulator control system to start discussion,the use of direct control structure,completed the hardware design and software design,including input and output modules,stepper motor control,microcontroller selection,select each drive module and so on. This paper describes the use of single-chip CPU as injection molding robot control system.This injection robot control system uses the corresponding circuit design. This paper describes the circuit design of the main control part of the dual-DOF manipulator by 28 BYJ-48 for stepper motor actuators,stepper motor drive module using ULN2003 chip,the controller aspect and using AT89 C52 reset circuit,crystal oscillator circuit design integration,keyboard input usingsimple matrix keyboard,display with digital display,the PS7219 chip driver,and finally through the whole hardware circuit simulation.The robot in ensuring its original performance under the premise of as much as possible to improve its characteristics that the performance and price ratio. And has a smaller size,simple structure and low price,and handsome appearance,the adjustment of the design to facilitate the convenience of the body close to the use of tools.
