Abstract
As society and the development of science and technology，Industrial
production operation mode has also undergone a revolutionary change, from
manual mill of labor, gradually evolved into automatic and intelligent mode
of production and human also gradually unable to complete some production
process, so in order to adapt to the needs of the production of the appeared
special production tools - manipulator. Meanwhile also appeared a few new
production activities in these production activities, some are belong to
high risk, to human body harm is larger, some areas not suitable for human
work is just, manipulator to meet this kind of work.
In today's large-scale manufacturers, enterprises to improve
production efficiency and ensure product quality, universal attention
production process automation degree, industrial robots as an important
member of automatic production line, gradually the enterprise recognizes
and adopted. Industrial robot technology level and USES degree in a certain
extent reflect a nation industrial automation level, at present, the
industrial robot main bearing welding, spraying, handling and stacking
repeatability and the intensity of labor etc greatly, work normally take
the reappearance of the demonstration teaching way.
Manipulator is imitating the people hand movement, according to a given
part of the program, track and requests to realize the acquirement, handling
and operation of automatic mechanical device. In this paper, three doff
industrial hydraulic structure of the manipulator are studied.
Keywords: three doff manipulator PLC system
