Features of OCR inspection

Inspection principle 

Tobacco is an industry specially controlled by the state and plays an important role in national economic and social development. Tobacco products must meet the relevant national standards, such as the packaging of tobacco products has very strict requirements. The OCR industrial visual inspection solution launched by KEYE Technology can perform intelligent identification in tobacco production and packaging, eliminate product production defects, and improve product quality.

System design

KEYE Technology OCR industrial visual inspection solution is a visual recognition inspection solution for the industrial field based on the AI ​​intelligent platform. It collects image information through high-resolution equipment such as industrial cameras and zoom lenses, and then completes the image information through the AI ​​​​intelligent platform. identification and processing. KEYE Technology AI intelligent platform has built a dedicated neural network architecture, which can automatically learn through standard template pictures. The scheme completes the information encoding of the image to be recognized through the neural network, uses the heuristic attention model to realize the decoding from the feature to the image information, and completes the precise identification of tobacco production, silk making process, coiling process and packaging process in packaging .

In the shredded process of tobacco manufacturing, it is necessary to process various tobacco leaves into shredded tobacco with a uniform ratio, no impurities, and a size and width that meet the requirements of the cigarette process. Using KEYE Technology's OCR industrial visual inspection solution on the tobacco shredded production line can accurately identify the shape, color, texture and other characteristics of tobacco leaves, and can also accurately identify shredded cardboard, shredded cartons, and hemp rope mixed in tobacco leaves and other impurities in order to remove impurities from tobacco leaves.

Inspection details

The tobacco rolling process includes cigarette rolling, filter tipping and other processes, and qualified shredded tobacco needs to be rolled into qualified cigarettes according to specified specifications and standards. On the cigarette machine production line, using KEYE Technology’s OCR industrial visual inspection solution, it can accurately identify abnormalities such as lack of cigarettes, missing mouth, reversed cigarettes, missing or deformed filters, etc. Packaging quality.

In the packaging process, the baked cigarettes need to be packaged into finished products that can be sold through packaging machinery. In the tobacco packaging process, the OCR industrial visual inspection solution of KEYE technology can be used to accurately read the cigarettes when the packaging line is moving at high speed. The two-dimensional code and unique characters on the packaging can effectively trace the cigarette supply chain; it is also necessary to identify whether the cigarette box is completely sealed, check whether the packaging paper is torn, and remove unqualified packaging from the production line .

Advantages of OCR system

• AI algorithm: high stability, adapting to the environment and background disturbance; different defect samples can be automatically identified after training
• Dataization: Independent database, save multiple samples, analyze non-good products, and retain history
• Multi-orientation: 360 ° comprehensive inside and outside the samples
• High precision: detection accuracy can be high
• Modularization, can flexibly increase or decrease the detection function according to customer actual needs
• Easy to operate: It is easy to operate and easy to maintain
• Safety: Medical grade material manufacturing, fully compliant with medical supplies production environment
