摘要
机械手在先进制造领域中扮演着极其重要的角色。在现代工业中,生产过程的机械化、自动化已成为突出的主题,机械手是在机械化、自动化生产过程中发展起来的一种新型装置。它可在空间抓、放、分拣物品、搬运物体等,动作灵活多样,能在有害环境下操作以保护人身安全,广泛应用在工业生产和其他领域内。
本文在近年来机械手发展状况的基础上,结合机械手方面的设计,对机械手技术进行了系统的分析,提出了用气动驱动和PLC控制的设计方案。采用整体化的设计思想,充分考虑了软、硬件各自的特点并进行互补优化。对物料分拣机械手的整体结构、执行结构、驱动系统和控制系统进行了分析和设计。在其驱动系统中采用气动驱动,控制系统中选择PLC的控制单元来完成系统功能的初始化、机械手的移动、故障报警等功能。最后提出了一种简单、易于实现、理论意义明确的控制策略。
通过以上部分的工作,得出了经济型、实用型、高可靠型物料分拣机械手的设计方案,对其他经济型PLC控制系统的设计也有一定的借鉴价值。

Abstract
Mechanical hand in the field of advanced manufacturing plays an extremely important role in. In modern industry, the production process of mechanization, automation has e a prominent theme, mechanical hand is in the mechanization, automation production process to develop a new device. It can catch, put goods, sorting, handling objects, flexible, can operate under the hostile environment to protect the personal safety, widely used in industrial production and other fields.
In this paper,by reviewing the developmental status of the manipulator in recent years, combining the design of manipulator and systematic analyzing technology of the manipulator, We proposed the design scheme that the manipulator was driven by the pneumatic and the system was controlled by PLC. Integrative idea was adopted in this design to fully consider the characteristics of the software and hardware plementary optimization. We analyzed and designed the overall structure, the implementation of structural, driving system and control system of the manipulator. We used pneumatic-driven in the driving system, PLC control unit in the control system plete initialization of the system, manipulator's moving, failure alarm and so on. Finally we put forward a control strategy which is simple, easy to realize, and clear theoretical significance.
Through the work above, a practical, economical, high-relia
