How to inspect QR code 2D code on packing labels by vision inspection system

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.

Models Of Visual Inspection Machine

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.
