What is OCR inspection

With the continuous improvement of living standards, food quality and safety have become the focus of social attention. People's requirements for food production are getting higher and higher, and the production date is an important criterion for us to evaluate food safety. Therefore, ensuring that the production date and other related information is correctly and clearly marked is an important link in the food production process. There is a very broad market demand for using machine vision technology to collect and detect bottle cap characters.

Inspection principle

As people have higher and higher requirements for product quality, product appearance quality inspection has become increasingly important. In recent years, with rising labor costs and the intensification of the market economy environment, many factories have gradually transformed and began to deploy fully automated production lines. , to improve production efficiency and save costs.

Among them, the common plastic bottle appearance and size inspection link uses the machine vision system, which greatly improves the product inspection efficiency and quality inspection accuracy compared with the previous manual inspection.

Inspection details

• The plastic bottle is connected to the screen printing machine and the visual inspection machine through the conveyor belt
• After the bottle falls on the conveyor belt, it will be sorted automatically
• The feeding mechanism on the conveyor belt automatically transports the bottles to the visual inspection machine.

It is a better method to use CCD vision to inspect the quality of product appearance defects. The appearance defect detection machine condenses a number of advanced technologies in the field of machine vision, and incorporates a number of innovative technologies to continuously innovate the detection concept of some non-standard product detection. It can be seamlessly connected with the existing production line for real-time online detection, and can also be offline to test.

While performing rapid detection of product appearance defects and internal defects of translucent materials, it can intuitively give feedback on production data reports. The detection is accurate, stable, and fast, which can greatly improve the flexibility and automation of production to improve production efficiency, and is easy to use. Realize information integration.

Advantages of OCR inspection

Plastic bottle CCD visual inspection equipment, based on machine vision technology, is a non-contact, non-destructive automatic inspection equipment for the appearance defects of various bottles such as dairy bottles, beverage bottles, medicine bottles, and daily chemical bottles. It can perform high-speed, 24 Uninterrupted inspection of bottle body, bottle bottom, and bottle shoulders for defects such as black spots, burrs, and lack of material, to a large extent overcome the low sampling rate, low accuracy, poor real-time performance, and efficiency of manual inspection methods Low, labor-intensive and other disadvantages.
