Vision sensors help provide 100% sorting
accuracy
Two In-Sight 5100 cameras are placed strategically within the sorting machine to inspect a number of different areas.
Pace Automation is a manufacturer of sorting machines that relies on Cognex vision to ensure one of its customers receives 100% accuracy on the production line Based in the eastern Franche - Comte region of France, Lisi Automotive is an expert in fasteners and mechanical assembly components and is a supplier to the automotive industry

The company specified that only Cognex vision products should be used in its new sorting machine.
Tasked with providing the high-performance vision solution, Multipix Imaging and JPS Imaging supplied the bespoke system to Pace Automation, which was then integrated in-house.
This particular system is required to sort speciality screws for the automotive industry.
The screws can vary in length from 40 to 60mm, placing high demands on the vision system.
Two In-Sight 5100 cameras are placed strategically within the sorting machine to inspect a number of different areas.
The first camera is charged with shank inspection and is required for part location, tip diameter and length measurement, thread measurement and thread counting.
This camera performs a series of thread measurements referenced from the located shank position.
Once the maximum and minimum Y co-ordinates are located thread diameter, thread root diameter, pitch and helix angle can be calculated All these measurements are calculated at 35-40ms per part.
The speed of the production line is 200-400 parts per minute, 24 hours a day, seven days a week, offering complete reliability and maximum throughput.
The second camera is required to find the flange diameter and part position as well as measure the diameter of the screw head.
The speed at which these measurements are calculated is approximately 25ms per part.
The system is calibrated to the known parts and all measurements and programmed inspections are sent via signal to a PLC which controls a reject system.
Any readings outside of the agreed tolerance are quickly removed from the line.
All images are logged with the information readily available to the operator.
