Abstract(s)
Perante a existência de não uniformidades em pneus, muitos fabricantes recorrem a
máquinas industriais, como aquelas desenvolvidas na Gislotica, que identificam pontos
distanciados irregularmente do centro geométrico do pneu com uma Quality Mark (QM),
através de uma marcação por transferência de calor, do inglês Label Thermal Application
(LTA). Estas máquinas industriais apesar de eficazes são bastante dispendiosas e rígidas,
não podendo ser reprogramadas. O objetivo deste trabalho consiste no desenvolvimento
de uma alternativa mais flexível com recurso a um robô FANUC, cumprindo os requisitos
impostos pela empresa. Neste sentido, foi feito um estudo das máquinas produzidas em
fábrica e de outros conceitos teóricos considerados fundamentais para a compreensão do
trabalho como as definições de pneu, robótica industrial e visão artificial. De seguida,
iniciou-se a componente prática do estágio com a montagem da ferramenta de marcação
e respetiva calibração recorrendo ao software ROBOGUIDE. A fase seguinte e mais
demorada do trabalho consistiu no desenvolvimento de um programa de marcação para
o robô e programação do PLC. Finalmente, foram realizados testes para validação das
implementações e da viabilidade do trabalho desenvolvido. Tudo isto encontra-se
devidamente documentado ao longo desta dissertação bem como as respetivas
conclusões inerentes aos resultados obtidos e cumprimento dos requisitos, dificuldades
encontradas e implementações de futuro.
Considering the existence of non-uniformities in tires, many manufacturers resort to industrial machines, such as those developed at Gislotica, which identify point irregularly distant from the geometric center of the tire with a Quality Mark (QM), through a Label Thermal Application (LTA). These industrial machines, although effective are quite expensive and rigid, and cannot be reprogrammed. The objective of this work is to develop a more flexible alternative using a FANUC robot, while meeting the company's requirements. In this sense, a study was conducted on factory-produced machines and other theoretical concepts considered essential for understanding the work, such as the definitions of tire, industrial robotics, and computer vision. Subsequently, the practical component of the internship began with the assembly of the marking tool and its calibration using the ROBOGUIDE software. The next and more time-consuming phase of the work consisted of developing a marking program for the robot and programming the PLC. Finally, tests were conducted to validate the implementations and the feasibility of the developed work. All of this is properly documented throughout this dissertation, including the corresponding conclusions regarding the obtained results and compliance with the requirements, difficulties encountered, and future implementations.
