HOTSPOT™️ No more loose flaps, no more collapsing multipacks.


The HotSpot™️, powered by Bytronic Automation, is a fully integrated quality control system that uses non-contact thermal imaging technology to deliver the perfect solution for hot-melt glue application quality control. The system ensures that every pack is correctly glued and folded with manual inspection.

"The HotSpot™️ provides a green manufacturing solution to companies looking to reduce their environment footprint, embrace sustainability, reduce waste and protect the environment."


100% inspection, zero contact with product.


Prevents collapsing multipacks.


Guarantee presence, location, size and temperature of every glue spot.


Ensures pallet stability.

Key Features

  • High precision gauging and calibrated temperature measurement.
  • A thermal camera detects the hot spots created by the glue.
  • A high-resolution vision camera determines the absolute position of the pack.
  • Deviation from specification such as missing glue, incorrect quantities, and misplace glue spots are rejected.
  • Technologies combine to determine the precise location and quantity of the glue on the pack.

How it Works

HotSpot™ uses LWIR imaging and traditional color imaging and is fully integrated into the system as the boxes emerge from the cartoning machine. The boxes are formed in the cartooning machines and hot melt glue applied to the flaps of the boxes. These are then folded to stick to the sides of the box to complete the assembly. By ensuring that the glue is the right temperature, and has been applied to the correct areas in the desired quantity, the manufacturer can be certain that the boxes are stuck together thoroughly, and are safe to be moved ready for transport.


The HotSpot™ vision system consists of a color camera and FLIR LWIR camera, looking at the edges of the box where the flaps fold over. The FLIR thermal imaging camera is providing a focused readout of the temperature of the glue and that it is in the right place, imaging through the cardboard material of the box. The color camera checks that the flaps have been properly formed and that the box is the correct shape. The vision application software used is Vision Pro software from Cognex. In the event of a failure, the line is automatically stopped and additional glue can be applied manually.
