What is OCV/OCR inspection

Optical Character Verification, OCV for short, is a machine vision software tool used to detect the printing or marking quality of optical ocr characters. This function can detect whether the content of the string is correct or not, and can also detect the quality, contrast and clarity of the string, and mark the defect position for unqualified products.

Inspection principle

As a new information storage, transmission and identification technology, two-dimensional code has developed rapidly in recent years. With the popularity of QR code applications, more and more manufacturers are considering spraying unique QR codes on product cartons, allowing users to scan and pay attention to public platforms or understand product information, so as to achieve the purpose of promotion and interaction and increase sales.

By scanning the QR code of the carton, you can quickly check the basic information of the whole box of goods, including product name, specification model, weight, batch, production date, place of origin, manufacturer name, etc. By setting different permissions, more traceability Information can be queried after inspectors and manufacturers scan the codes.

Inspection solutions

• According to the actual situation on site, evaluate the installation of industrial cameras on the conveyor belt.
• When the carton flows into the vision inspection station, two machine vision sensors are triggered to take a picture of the item and send it to the system. The system takes and analyzes a picture of the carton and compares it to the settings to see if the inkjet code on the carton is correct and if the 2D code is readable.
• When it detects the wrong characters on the carton, the unreadable QR code, etc., the system will send out an ng signal and an alarm prompt.

The visual detection system for carton coding is designed according to actual production requirements, and can quickly and stably detect missing spray, less spray, misalignment, fuzzy printing, offset printing and other required items. It has the characteristics of simple operation, stable operation, fast speed and convenient maintenance. The flexible installation method can not only seamlessly cooperate with the customer's assembly line, but also provide comprehensive testing assembly line equipment, which is convenient for customers to choose according to their needs.
