文档介绍：4-DOF搬运机器人的结构设计
摘要:在当今大规模制造业中,企业为提高生产效率,保障产品质量,工业机器人作为自动化生产线上的重要成员,逐渐被企业所认同并采用。工业机器人的技术水平和应用程度在一定程度上反映了一个国家工业自动化的水平。目前,工业机器人主要承担着焊接、喷涂、搬运以及堆垛等重复性并且劳动强度极大的工作。
本文研究了国内外机械手发展的现状,通过学****机械手的工作原理,熟悉了搬运机器人的运动机理。在此基础上,确定了四自由度搬运机器人的基本系统结构,对搬运机器人的结构进行了简单的强度计算,完成了搬运机器人机械方面的设计(包括传动部分、执行部分、驱动部分)和简单的三维实体造型工作。本设计为四自由度圆柱坐标型工业机器人,其工作方向为两个直线方向、一个旋转方向和一个气爪运动。机器人的机械结构主要包括由三个电磁阀控制的气缸来实现机器人的上升下降运动及夹紧工件的动作,一个步进电机控制机器人的正反转。
在控制器的作用下,搬运机器人执行将工件从一条流水线拿到另一条流水线这一简单的动作。设计的搬运机器人运用于自动化生产线,实现自动化生产,减轻产业工人大量的重复性劳动,同时又可以提高劳动生产率,本文是对整个设计工作较全面的介绍和总结。

Abstract:In the modern large-scale manufacturing industry, enterprises to improve productivity, and, guarantee product quality, as an important part of the automation production line, industrial robots are gradually approved and adopted by enterprises. Industrial robot technology standards and application level, to a certain extent, reflect a level of national industrial automation. Currently, Industrial robot mainly tasked with welding, spraying, handling and stacking, repetitive and intensity of significant work.
This paper studies the current situation of the development of mechanical hand, by studying the working principle of the robot, familiar with handling robot otion mechanism . On this basis, identified 4-DOF of handling robot 's basic system architecture , simple strength calculation was made on handling robot structure , finish handling robot mechanical design ( including transmission part, operative, driving part ) and simple 3D solid modeling scheme introduced a cylindrical robot for four degree of freedom. It posed of two linear axes ,one rotary axis and a pneumatic claw manipulator mechanical structure includes three solenoid valves controlled by air cylinder to achieve the increased decline in sports and workpiece clamping action, a stepper motor control manipulator positive inversion.
