[摘 要]
在工业生产和其他领域内，由于工作的需要，人们经常受到高温、腐蚀及有毒气体等因素的危害，增加了工人的劳动强度，甚至于危及生命。自从机械手问世以来，相应的各种难题迎刃而解。机械手可在空间抓、放、搬运物体，动作灵活多样，适用于可变换生产品种的中、小批量自动化生产，广泛应用于柔性自动线。机械手一般由耐高温，抗腐蚀的材料制成，以适应现场恶劣的环境，大大降低了工人的劳动强度，提高了工作效率。机械手是工业机器人的重要组成部分，在很多情况下它就可以称为工业机器人。工业机器人是集机械、电子、控制、计算机、传感器、人工智能等多学科先进技术于一体的现代制造业重要的自动化装备。广泛采用工业机器人，不仅可以提高产品的质量与产量，而且对保障人身安全，改善劳动环境，减轻劳动强度，提高劳动生产率，节约原材料消耗以及降低生产成本，有着十分重要的意义。

The application of PLC in Manipulator Moving Control System
Abstract:
In the industrial production and other fields, people often endangered by such factors as high temperature, corrode, poisonous gas and so forth at work, which have increased labor intensity and even jeopardized the life sometimes. The corresponding problems are solved since the robot arm comes out. The robot arms can catch, put and carry objects, and its movements are flexible and diversified. It applies to medium and small-scale automated production in which production varieties can be switched. And it is widely used on soft automatic line. The robot arms are generally made by withstand high temperatures, resist corrosion of materials to adapt to the harsh environment. So they reduced the labor intensity of the workers significantly and raised work efficiency. The robot arm is an important component of industrial robots, and it can be called industrial robots on many occasions. Industrial robot is set machinery, electronics, control, computers, sensors, artificial intelligence and other advanced technologies in the integration of multidisciplinary important modern manufacturing equipment. Widely using industrial robots, not only can improve product quality and production, but also is of great significance for physical security protection, improvement of the environment for labor, reducing labor intensity, improvement of labor productivity, raw material consumption savings and lowering production costs.
