Packaging Operations
Problem: On a high-speed packaging
line, efficient methods for non-
destructive testing of a glued box seal
are scarce, and most tend to be very
cumbersome. In addition, the glue
The Problem
• Optional features in vehicles cannot be
inspected without some type of contact.
• This slows down production.
• 100% inspection is tedious.

The Problem
• Detect incorrectly sealed boxes.
• Remove failed units from the line.
• Generate an alarm if too many boxes fail.
• Log statistical data of pass/fail.

Typical Monitoring and Control Applications
application method has a good deal of
variability that must be monitored and
recorded with statistical quality control
routines.
Solution: Since the glue is heated prior
to application, its temperature and
The Solution
• An IR camera can be permanently mounted to
inspect these items.
• An IR camera can be used in a non-contact
method.
The Solution
• Capture a thermal image of the box.
• Detect presence of glue spots.
• Pass/fail on each box.
• Log statistics.
