Detecting problems with PSAs

March 26, 2024
Vision Optronix’s system, integrated with digital inputs and outputs for process control and monitoring, provides manufacturers with a cost-effective solution that minimizes losses and improves operational safety and efficiency

A pressure-sensitive adhesive (PSA) manufacturer in the medical field is facing challenges due to yield losses caused by wrinkle defects on their web-based manufacturing line, Automation World reported.

These defects, which are difficult to detect with the human eye due to the thin and sheer nature of the materials involved, lead to significant losses in raw materials, labor and overhead costs. Moreover, if these defects are not identified and rectified before shipment, they can result in customer rejections and tarnish the reputation of both the manufacturer and the medical facilities using the products.

To address this issue, the manufacturer collaborated with system integrator Vision Optronix to develop a custom vision system capable of detecting and localizing wrinkle defects during fabrication, thus allowing for immediate remediation and marking of defective areas before shipping.

Vision Optronix conducted a thorough analysis of the problem, designing and implementing a comprehensive vision system equipped with specialized cameras, lighting systems, and image processing algorithms. Through collaboration with suppliers like Teledyne Dalsa and CPU Automation, they selected suitable components to optimize contrast and imaging performance, ensuring effective defect detection at the required line speeds.
