Italian company Multiphysics Diagnostics Automation (MDA), who focus on providing solutions based on a multi-physics approach, has placed SmartRay ECCO sensors at the core of its production line due to their wide field of view, high-speed performance and integration into machines. Working for a machine builder that uses automatic production lines for gas cylinder manufacturing, MDA designed a contactless system that uses 3D vision to check the correct shape of the top and bottom caps right after the deep drawing process and before the welding process. The ECCO sensor extracts the profile information, which is then matched with the desired shape.
One of the challenges of this application was the metal and shiny surface of the parts, which the ECCO 55.100 sensor was able to manage perfectly, producing a high-quality profile of the inspected part. Thanks to the 3D vision system, whenever a non-conformity was detected, the part was immediately rejected, avoiding the time and expense of further processing. The profile captured by the SmartRay ECCO is compared with a threshold range with an accuracy of 0.1mm.
The measurement can be made on a number of positions, all of which can be defined by the user. With the expert help of Smart Ray, MDA s.r.l developed a solution that prevents non-conforming parts from proceeding to the welding step, saving both the time and costs caused by further processing. Sergio Badocco, owner of MDA commented “Before the implementation of the system, a manual measurement was made on the random samples using a jig tool, which took at least two minutes.
With the SmartRay sensor it takes five seconds to automatically check the surface, resulting in 96% of time saved for a single check. It is now possible to inspect 100% of production.”
