The thesis addresses the process of planning a program for two ABB Robotics
robot arms, that work in an industry cycle and handle two injection moulding
machines, with regard to the nature of the end product, that consists of an
aluminum base and two different polymers, that are injection molded onto the
base. The thesis also describes the layout and short description of machines
inside the enclosure, that make the whole process possible, but the main focus is
on programming in RobotStudio.
The main two problems we tackle are the time constraint of one cycle and
the stage of autonomy of the enclosure, which was specified at 50%. Because of
the time constraint we decided to use two 6 axis robot arms and two injection
moulding machines. With that decision we have each robot handle one of the
injection moulding machines and we can work with only one half of the whole
enclosure, which was one of our goals set by the buyers.
We started planning the program with identifying the slowest process in the
enclosure and focused on trying to use the time, spent by that process, to do as
many other tasks as possible. The slowest part in our project was the heating
unit, where we heat up the aluminum base of the part, before putting it in the
injection moulding machine. While waiting for the base to heat up we can finish
one cycle and finish a pair of end products. After the moulding process the
products have to be checked with cameras for any faults.
Our final solution solves the problems and satisfies the conditions set by the
buyers. With more time and resources we could improve the solution, but in our
case that was not needed.
