During the Chinese New Year, everyone inevitably engages in shopping sprees . Especially in the lead-up to the New Year, wholesale markets, large supermarkets, convenience stores, and e-commerce platforms all experience a surge in purchases. Customer traffic and sales volumes increase significantly compared to normal times. For businesses, such a huge opportunity cannot be missed, making product quality paramount. Just as " clothes make the man , " the same applies to products.
Incorrect or damaged product packaging can negatively impact consumers' perceptions of product quality, safety, and value. To avoid damage and maintain brand loyalty, consumer packaged goods manufacturers rely on machine vision to inspect primary and secondary packaging to ensure it is correct, tamper-proof, and free of defects. This helps manufacturers guarantee that only the highest quality products reach their customers. Cognex possesses a unique advantage in providing high-performance solutions for consumer packaged goods manufacturers, as well as the machine manufacturers and systems integrators who provide these services, enabling improvements in product safety, quality, and productivity.
Cognex's " Three Types of Testing " for Consumer Product Packaging
Capping test
3D laser displacement sensors provide precise micron-level 3D inspection in real-world environments, helping to optimize product quality. DS1000 laser displacement sensors above the conveyor transporting open boxes ensure that each bottle cap is properly tightened. Before the boxes are sealed and loaded onto the truck for shipment, any loose caps are marked. This prevents leakage and isolates defective products before they leave the facility.
Packaging Inspection
Cognex's deep learning-based image analysis excels in package detection because it can infer functional characteristics of items, such as size, shape, and surface features, from training images. The ViDi blue tool identifies and counts parts within a package. The ViDi green tool uses a deep learning model to classify items by category. Combining this information, it's possible to determine whether a multi-part assembly contains the correct items.
Tamper-proof and secure seal inspection
The DS1000 3D laser position sensor can locate tampered seals and verify their integrity for accurate and repeatable inspection. Three-dimensional inspection ensures the security seal covers the entire opening, with no bubbles or wrinkles around the edges, and no holes or perforations. Tamper-proof seal dimensions that do not meet programmed limits will be rejected.
