The Catalan enterprise, founded in 1984, is a global Tier 1 leader providing shielding solutions to reduce heat and noise and eliminate electromagnetic interferences by means of metal based stamping parts. It currently manufactures more than 22 million shields per year, and it is a worldwide player with strong presence in the European, Asian and North American markets. They own the following certifications:
• IATF 16949 - Quality management system for automotive production
• ISO 14001 - Environmental Management Standard
• OHSAS 18001 - Occupational Health and Safety Management
The company has an automatic cold stamping line, which produces more than 15 different references. An operator placed at the end of the automated production process (figure-01), grabs the stamped parts that leave the machine on a conveyor belt and visually inspects them one by one to detect the most common defects, namely:
• Cracks of 0.3 mm in length or greater with different shapes.
• Lack of material.
Now, the company wants to improve the quality control implementing a computer vision-based technology to detect defects, which is mainly expected to:
• Perform an objective and constant unitary verification of the parts.
• Satisfy the increasingly demanding quality requirements of their market.
• Reduce the ocular fatigue of the operators.
• Allow savings in materials and energy consumption by early detection of the root cause of defective parts.
The technology sought should be fixed on the machine soundproof enclosure (figure-01), and be able to continuously monitor the parts moving on the conveyor belt to detect defective units.
The company is interested in a research or technical cooperation agreement with a partner with whom to collaborate in the development and implementation of the computer vision based solution.
