Description

Technical Field

[0001] This utility model relates to the field of tobacco detection technology, specifically to an image detection device for tobacco. Background Technology

[0002] Projection inspection equipment used in the tobacco industry is mainly used for quality control and inspection of tobacco products, and includes the following types:

[0003] 1. Cigarette Appearance Inspection: Inspecting the geometric parameters of cigarettes, such as diameter, roundness, and length; identifying surface defects such as wrinkles, stains, and damage.

[0004] 2. Filter tip inspection: Check the quality of filter tip assembly; measure the length and positional accuracy of the filter tip.

[0005] 3. Tobacco distribution detection: Analyze the uniformity of tobacco distribution within the cigarette through projection images; detect changes in cigarette density.

[0006] These types of equipment have become an important part of quality control in modern tobacco production lines, helping to improve product consistency and production efficiency. However, current projection inspection equipment for tobacco still has some shortcomings. Existing inspection equipment generally uses a single light source, that is, lighting from the top image acquisition unit downwards.
