eVS has designed a system for automatic verification of corrugated metal sheet profiles from a moulding machine. Profiles are checked against a golden reference acquired off-line during the system initialization.

The system allows:

• Quality control on samples
• Monitoring the production process
• Putting production on halt when non conformities are detected
• Provide data on possible causes behind a non conformity

At a glance

The system is based on a laser blade projected on the corrugated metal sheet profile. The laser blade is then framed with a camera with 3D acquisition capabilities. Spanning the laser blade on the the whole profile makes possible reconstructing the height of every section of the target object.A setup with multiple sensors / laser systems can support a wide scan area.

Operations

A straightforward interface provides operator with core information about manufactured profiles while the underneath system performs control steps such as:

• Acquiring the corrugated metal sheet profile from the moulding machine
• Comparing the acquired profile with a golden reference
• Computing whether the acquired profile is within tolerance for the production lotto
• Communicating with plant PLCs for alarm conditions and keepaliving
• Serializing non conformities to a local storage for later analysis and statistics
