Description

Technical Field

[0001] The utility model relates to appearance detection equipment, in particular to packaging box appearance detection equipment. Background Art

[0002] During the production process of toothpaste, the toothpaste needs to be placed in a packaging box, and then a layer of protective film is plastic-sealed on the outside of the packaging box. In order to make a combined toothpaste, at least two toothpaste packaging boxes need to be plastic-sealed together. However, since there are multiple packaging boxes to be plastic-sealed, there may be undesirable conditions such as corner shrinkage and damage of the plastic film. Therefore, quality inspection is required before leaving the factory. Traditionally, manual visual quality inspection is used, which not only increases labor costs, but also makes manual visual observation for a long time prone to fatigue, resulting in false detection or missed detection. Therefore, CCD cameras are currently used for shooting and detection, but the installation of existing CCD cameras is relatively fixed, and cannot be adapted to the detection of products of different models and sizes.
