Factory automation today has gone leaps
and bounds except in South east Asian market, where the labor seems to be still
cheap and very much available in comparison to the automation machine required
for normal processing.
What are Robots:
They are mechanical structures which are
made to satisfy various functions or could be function specific and it has
controlled brain using various electronics and software controls to function as
per the design in the 3D world.
Robots on the co-ordinate planes can work
on 2,3,5,6 etc.. axis plane and more as per the functions.
The robots are specified with it’s
Weight, Payload, Functions, Size, Area of reach, Controller, Controller I/O & Function
dependent specifications.
Today we will take an example of the
Fanuc Robot M10iA(Robot Arm) and will explain the basic of it’s design and
functions.
This is a robot designed for below
application but your engineering eye could shape it in your way:
Material
handling-> The Chuck at the J6 can
have magnet or gripper attached for the function.
Machine
tending-> With the special tool
,chuck or gripper it can be used for
Assembly-> In the assembly line it can be used between multiple
machine for various jobs.
Picking
& Packing-> It would be same as
the material handling and one can use
various sensors for apt. picking.
Material
removal-> With the turning tool or
etc. one can use this as drill tap center or such functionality.
Testing
& Sampling, Dispensing-> For
the entire cycle of inspection ,sampling and dispensing it would be programmed
for doing all the function with different mechanical attachments.
Now in the isometric view you can already
see the positive and the negative circular movement for each axis/joint i.e J1
to J6 (J=Joints).
The program has to be made by programming
the different axis on the robot using the TEACH PENDANT. This teach pendant
helps the robot move in the direction it wants too as we move the
linear/rotational axis on the machine.
There are several modes to make the robot move in the desired location.
Auto: Use the programming software for
Robot and insert it using some communication protocol.
Teach In: Yes! You can teach your robot
how to move and where to move and save the path for it.
After that one can interface/program the
some feedbacks and outputs to see that it functions safe as per the CE or
standard norms via free I/O provided and the PLC modification software provided
by the MTB.
The clamping of the end element is by
various methods depending on the payload i.e. the clamping of the end element
may be pneumatic, magnetic, hydraulic or electromechanical linkages. With Fanuc
M10iA it is pneumatic clamping.
With the dimensions and the notes in the
below drawing one can understand the robot functionality easily.
