Abstract
The technology device used to reproduce the staff function is called a
mechanical hand, the mechanical hand is imitate the action of the manpower, to
achieve a given program, track and requirements automatically grab, handling or
operation of automatic mechanical device. Robots can replace the hands of
heavy labor, significantly reduce the labor intensity, improve working
conditions, and improve labor productivity and automation level.
The technique level and the application degree of industrial robots reflect
the national level of the industrial automation to some extent, with the
popularity of industrial automation and development, handling the application of
mechanical hand gradually popularity, mainly in the automotive, electronic,
mechanical processing, food, medicine and other areas of the production line or
cargo transport, we can be more good to save energy and improve the transport
efficiency of equipment or products, to reduce restrictions on other modes of
transportation to meet the requirements of modern economic development.
This manipulator is mainly used for metal optic axis handling work, can
match with machine tools (such as forging bed, NC machine tools, combination
machine tools) or assembly line of weight to realize cylindrical work pieces
handling. The robot will use the three degrees of freedom for the pneumatic
drive. First, I design and calculate the hand, wrist, arm and various parts of the
mechanical hand. Then choose the proper drive method and transmission
method, build the mechanical structure of the mechanical hand. Second, design
and wire the electrical control system on the base of the pneumatic system of the
manipulator. Their course of action should include: decline in clamping
increased, slow forward, fast forward, slow progress, the extension of , the drop
in, relax, rise, slow back, rewind, slow back; its operation, including: back in
situ, manual, single-step, single cycle, continuous; and finally complete the final
requirements of the handling robot porter pieces.
Keywords: mechanical hand, transport, structure, pneumatic , programmable
logic controller (PLC).
