Abstract [en]
This work is being carried out in collaboration with the TYRI Light industry to improve their existing assembly line, which currently has 8 stations. Out of these, three stations are operated by humans, and the rest are automated. The main focus of this project is on the first station, which is currently operated manually. While another master’s student from University West focuses on improving an automated second station and enhancing the fourth station, which is operated by a human worker. The seventh station, which operated manually, requires a human worker because of its complexity and flexibility of human.At this first station, there are two tasks involved. The first task is picking up components and placing them on an empty fixture, while the second task is picking up the finished product from the fixture and placing it on the palletizing process. Currently, it takes 19 seconds for a human worker to complete these tasks before sending the fixture to the next station.The goal of this project is to investigate whether this first station can be improved by using a robot instead. If a robot can perform these two tasks faster than 19 seconds, enhance workplace safety, and handle both tasks effectively without a need for more robots or external assistants. To achieve this, a discussion was made with the TYRI supervisor to select a collaborative robot for this task. To validate the work, ABB RobotStudio simulation software is used. The collaborative robot should be equipped with a specially designed gripper, which is suitable for the collaborative mode. Furthermore, in order to make the gripper suitable for TYRI’s components measurements, it was customized by a mechanism feature, which RobotStudio has.With the help of literature studies and various methods, the successful implementation of the robot was achieved. The robot was integrated outside the assembly line and was able to handle both tasks at the first station. Which indeed improved workplace safety. However, the robot took a total of 30.8 seconds to complete the tasks, which is longer than the 19 seconds goal was aimed for. As a result, the robot didn’t meet the desired cycle time required in this case
