Label inspection with a camera on the production line
Label inspection from Robopipe checks on every piece that the label is there and sits right, the batch code can be read and the best-before date is on the label.
What label inspection checks
Label inspection with a camera checks four things on every piece:
- Label present. The camera marks a piece without a label as NOK.
- Position and orientation. The label must sit in the right place and must not be turned.
- Legible batch code. The camera checks that the batch code can be read.
- Best-before date. The camera reads the best-before date from the label.
Operators see the verdict on a display on the floor. An image of every check stays in the archive, so you can find it for an audit.
Reading the best-before date
Reading the best-before date runs on every piece right on the line, like the other label checks. The camera reads the date from the label and the result goes to the operator display with the other checks.
Print inspection
Print inspection is the same task. The camera checks that the print on the pack is in place and legible. The model learns from images of your correct and faulty pieces, so nobody writes rules for each kind of label.
Label inspection is part of machine vision. The guide to machine vision gives an introduction to the field.

Label inspection FAQ
Can the camera handle different labels on one line?
Yes. You add each kind of label to the inspection as a product yourself in the Studio app. The pricing page shows how many products a plan includes.
Can the camera read the best-before date?
Yes. The camera reads the best-before date from the label on every piece right on the line. In a demo, we show you how it works on your own labels.
What happens to a piece without a label?
The camera marks the piece as NOK and operators see it on the floor display. The control unit can trigger your existing reject unit or signal light. The image of the piece stays in the archive.
What if we change the label?
You add images of the new label and retrain the model. The Standard plan has 5 model trainings a month, the Pro and Enterprise plans have no limit.
