Aluminum Can Inspection
Cut waste with high-speed, 3D, quality can inspection
The packaging of products can be as important as the products themselves. (Think of the intricate packages used to ship electronics and high-end food stuffs.) Adding complexity to packaging are products that require quality verification in a regulated industry, such as food and beverage or pharmaceuticals. In the food and beverage industry, packaging-quality verification protects brands and people from spoiled products, allergic reactions, and other potentially damaging or fatal results.
For example, aluminum cans with easy-to-open tabs may have dents on the top, missing tabs, or lifted tabs. A slight dent or a lifted tab is difficult to detect with a 2D imaging system. High-speed, accurate, true 3D solutions are needed for applications that require this level of precision. Solutions should also require minimal training and ensure packaging quality without creating extra waste or rework.
The Difference a Degree Makes
In food and beverage packaging, a small defect in a can or a tab lifted by just two degrees can result in a failure. To achieve higher levels of detection without long training programs or disrupting production, Cognex developed the In-Sight 3D-L4000 In-Sight smart vision system. This high-performance smart camera delivers the best-quality, patented laser imaging technology, capable of detecting:
- 3D blobs
- 3D edges
- Surface angles
- Step heights
- And much more
The In-Sight 3D-L4000 from Cognex with the In-Sight software and 3D vision tools makes quick work of can-quality inspection, cutting down on rework and boosting productivity.
Moreover, with both 2D and true 3D vision based on point cloud measurements, not just height maps, the In-Sight 3D-L4000 measures distances between blobs and features for advanced machine vision applications and achieves greater accuracy than traditional laser scanning solutions. Additional advantages include better performance and safety due to advanced optical design, and simple programming using the In-Sight software environment, which includes 3D Edge, 3D blob, plane finding and many more features. The In-Sight 3D-L4000 is what the vision industry has come to expect from Cognex: a camera that delivers the highest-quality 2K resolution images, up to a 4 kHz scan rate, patented speckle-free blue laser optics, and software, with the broadest and most powerful 3D vision tools. All of which work together to generate fast, accurate, and repeatable results.
Benefits of Working in “Real” 3D
Many production line workers are already familiar with In-Sight software. Modeled after the industry leading 2D vision tools, the true 3D vision tools work directly on the 3D image so workers can learn the system in minutes and achieve functional mastery in three hours or less. The interface offers access to accurate imaging with the ability to present color-coded, highlighted, and text data to communicate selected features in an easy-to-use spreadsheet. The In-Sight 3D-L4000 is available in three models to meet application-specific requirements based on defect detection needs across various fields of view.
