Description

An industrial camera support structure for cigarette case appearance defect detection

technical field

The invention relates to the technical field of cigarette case detection, in particular to an industrial camera support structure used for cigarette case appearance defect detection.

Background technique

The appearance image is printed on the outer surface of the cigarette case. If the image position, color, shape and shape of the cigarette case are defective, the market will reduce consumers' favorable impression of the product, so the corresponding positions of each outer surface of the cigarette case are fixed. An industrial camera, each camera takes a picture of an outer surface of the cigarette case, and then uploads the data to the computer for comparison with the preset standard data, screening out the cigarette case with defective appearance, and improving the packaging qualification rate of the cigarette case. However, the area where the adjacent outer surfaces of the cigarette pack intersect has a problem of photographing blind spots.

Now, an industrial camera is arranged on the outside of the cigarette case and rotates in a circle around the cigarette case, which can take pictures around the cigarette case and reduce the blind spot for photography. However, the existing cigarette boxes are all in the shape of a cuboid, and the industrial camera makes a circular motion around the cigarette box. The depth of field of the camera is different for each area. After uploading to the computer, it increases the difficulty of comparing with the standard data pre-stored in the computer.
