Automated optical inspection in automotive assembly line

Abstract

Quality is becoming more important instrument of competition in industry of technology. A product with decent quality sells well in the market and increases the image of the company. In addition the quality increases profitability. The aim of this work is to design an automated quality inspection gate before test run. Quality inspection is already conducted by a human worker but objective is to expand quality inspection with a robot and smart camera. The work presents different kind of inspection systems from manufacturing industry. The system requires a robot in order that a smart camera can be moved easily and all camera angles can be reached. The system could be designed to be part of manual quality gate and that’s why this work presents light weight robots which can co-operate with a human without external safety equipment. One of the objectives is also to find which features are important and how they could be inspected automatically.
