Inline Automatic Optical Inspection Machine Vision System Detecting Labels and Barcodes

Package is the direct image for customers to read the details of the commodity that they are going to buy. A package is usually finished inline after the commodity is produced, at the same time, labels and barcodes are printed or self-adhesived on the packages or the packing boxes. What if the labels and barcodes are wrong?

An inline optical inspection system is indeed to solve this concern. The system was designed with machine vision technology,  combined with commodity features, designed with a specific image capture and processing system. It can read the barcodes, images, and text on the labels. When incorrect labels is found, the system can automatically eject out. So all the labels will be correct before packed on the commodity.

For example, bottles with caps. The common packaging contents are QR 2D Codes, Production Date/Warranty Date. Some caps will be printed with barcodes, and they have an obvious feature, that is, massive production, which requires high quality printing information.


Some caps of food package will print the date of production. Usually they use printer or laser printer. The printer is more flexible and widely, but it has defective problems, like bending, unclear, missing information and etc. The laser printer is less widely used, and it will have the problems of re-print, missing information and etc. If we use human inspection, there is a large labor work and the speed is slow.


Sipotek in this way can solve the problems instead of human inspection, we can provide automatic online testing solutions and sort out the unqualified printings with problems such as unclear, deformation, wrong code, dot-code unable to connect problem and etc.

Take a drinks’ production date for example,


  1. Caps printing character detection

The printed characters are on the curved surface of the bottle cap, the concave and convex stripes are obvious, but the visual inspect is difficult. Sipotek lighting improves the character’s background color. The character is black, so it feels on a plane with the background, and the color text is distinctive for detection.


  1. Outer package printing character detection

On the outer packaging, the barcode will be printed on the product and on the label so that the company can establish a tracking system to meet the requirements of collecting product barcode information in actual time. Sipotek system, with its outstanding code reading ability, can accurately and quickly read characters on a variety of packaging materials.


With the increasing quality standards of food industry, sorting machines are required not only to detect the character, but also in machine vision, bar code, QR code reading, verification process, it plays an important role.


Sipotek specialized in Machine Vision system solution for over 16 years, it has an excellent privilege technology on automatic online inspection system and 2D code identifications.
