360° View of Screw Cap Lids in a Single Image

Challenge

In the food industry, product quality and packaging integrity are essential. After filling soup jars, even small surface defects such as scratches on screw cap closures can negatively impact brand perception and lead to customer complaints. Conventional inspection methods often fail to reliably capture the entire outer surface of a lid at production speed, particularly in inline applications.

The challenge was to ensure complete and consistent quality control of screw cap lids without slowing down the production process or increasing system complexity.

Application

The inspection system is used after the filling process to check the quality of screw cap closures on soup jars. The goal is to detect scratches and other surface defects on the outer surface of the lid while the jars move through the production line. The solution had to provide a full 360-degree view of the lid surface, operate inline, and maintain high throughput without compromising inspection accuracy.

Solution

senswork developed a compact 360° camera inspection system that enables a complete view of the screw cap surface in a single image. By using mirror deflection technology, the system captures the entire outer surface of the lid without the need to rotate the jar. This approach allows reliable detection of scratches and surface defects while keeping the system layout simple and efficient. The inspection is fully integrated into the production line, ensuring continuous quality control directly after filling.
