Setup in two ways

Even though some new sensors can be set up without external hardware, some manufacturers still include PC connectivity. Often, results and configurations can be downloaded to a USB drive to be stored and referenced on a PC. (USB ports on sensors can also be used to upload new configurations.) Here, users setup new inspection parameters offline using the sensor's software emulator, then upload them to the sensor through the USB.

Aside from detecting the package itself, label detection and verification are key to ensuring proper packaging. Image sensing is often used to confirm proper label placement and orientation. Following the trend of consumer goods, touchscreen image sensors now allow users to setup and configure inspections right on the plant floor.

First, users acquire an image of a “good” part — a container with a properly affixed label — with which to compare all other products inspected. Then, the user can configure the sensor to look for a match. Upon acquiring the image, the image sensor makes a determination: Products correctly labeled pass inspection, while improperly labeled items fail and are rejected from the line.

The same technology can prove particularly useful for verifying date and lot codes on pharmaceutical products, both for tracking and to prevent counterfeits.
