The Epic Solution

EPIC designed, fabricated, and integrated a state-of-the-art 2K color line scan imagery machine to showcase detailed product imagery in the highest possible resolution. The project successfully created a PLC-based integrated-control batch identification system that showed clear, high-resolution images of the products’ qualities and defects.

The system exceeded the client’s high demands and requirements for each image passing through the servo-powered product line. It achieved a higher QA protocol than the client’s competitors.

EPIC’s solution ensured that product inspection experts were sent detailed, high resolution images of product batches for Quality Assurance Inspectors to examine. The images were of such high detail it eliminated the need for these experts to visit each of the manufacturing facilities to conduct inspections.

Product batches were first scanned using a 2D Cognex barcode for proper identification. The cylindrical products were then moved along to a high-speed revolving conveyor belt, where the vision imagery process began after the system’s operator used the pressure-activated start button.

As the operator continuously placed product batches on the conveyor the system’s 2K color line scan cameras were activated. These cameras captured high-resolution images at the conveyor belt’s high speeds and displayed them on an HMI monitor programmed with lab view technology.

The client achieved a fully functioning batch identification system that provides high resolution images to showcase the qualities and defects of batched products. The fully automated vision system for uniquely shaped products allows the company to have a higher QA protocol than its competitors.
