Vision King – Metal Panel Stamping

Technology Description

The primary objective is to identify defects and imperfections on the surface and edge of stamped steel panels, including:

Cracks and
Tears

Crack on the stamped panel

Depressions
and Wrinkles

Depression on the stamped panel surface

Burrs and
Edge Damage

Burr on the edge of the stamped panel

Stamping
Marks

Draw mark on the stamped panel

Distortion
and Waviness

Distortion on the stamped panel

Computer vision applied to the inspection of stamped steel panels has become an essential solution for ensuring quality in Class A surface processes, such as in automotive doors, deck lids, hoods, and roofs. Vision King uses cameras and image processing algorithms to detect defects, irregularities, and specific characteristics on the steel surface that are difficult to identify with the naked eye.

Advantages

  • Safety and Real-Time Capability:

    Computer vision technology can operate in conditions that pose ergonomic risks to people.

  • Precision and Consistency:

    Computer vision technology aligns with precise and consistent parameters, which helps reduce human errors.

  • High Speed:

    Real-time analysis enables the immediate detection of defects and allows for interruptions in case of equipment risks. This significantly increases tool lifespan.

  • Increased Quality:

    The system’s total and immediate analysis of production helps detect issues stemming from machinery, tools, or even mechanized handling. This prevents defects from spreading throughout the batch and allows for proactive improvements.

  • Analysis and Reporting:

    Computer vision systems can collect data over time, enabling the identification of trends and root causes of defects, as well as optimizing processes.

  • Cost Reduction:

    The technology reduces the amount of scrap generated across all phases of the production process. It also decreases the number of tool verification tests, thereby extending equipment lifespan.
