AI Technical Summary
Technical Problem
Existing methods for detecting the outer surface of containers require multiple camera devices and complex image processing, resulting in high costs and low efficiency.
Method used
A first camera unit is used in conjunction with a circular concave mirror and an illumination unit. The image of the outer surface of the container is displayed on the circular concave mirror through a reflection unit for detection. Combined with translation, lifting and gripping mechanisms, the automatic detection of the inner and outer surfaces of the container is realized.
Benefits of technology
It reduced testing costs, improved testing efficiency, and enabled complete automated testing of the inner and outer surfaces of containers.

Abstract
This application discloses a container outer surface inspection mechanism and an inspection device using the same mechanism, relating to the field of container inspection technology. It includes a first imaging unit, an illumination unit, and a reflection unit. The reflection unit has a feed inlet and an annular concave mirror. The illumination unit provides a light source for the container and projects an image of the container's outer surface onto the annular concave mirror. The first imaging unit captures the image of the container's outer surface projected onto the annular concave mirror. When inspecting the container's outer surface, the container is placed into the reflection unit through the feed inlet. The illumination unit illuminates the container, projecting an image of its outer surface onto the annular concave mirror. The first imaging unit then captures the image from the annular concave mirror, thus inspecting the container's outer surface. This configuration allows for the inspection of the container's outer surface using only a single first imaging unit, reducing inspection costs and improving inspection efficiency.
