How it works

Cartons are formed then hot melt glue is applied to the carton flaps. The flaps are then folded and sealed to the carton sides to complete the assembly. By measuring that the glue is at the required temperature, has been applied to the correct area and in the desired quantity, you can be assured that the carton will not fail and is safe to be transported. Missing glue means potential breakages in logistics or at the point of sale. Badly shaped cartons means poor product sales.

The HotSpot vision system consists of a colour camera and FLIR LWIR camera, inspecting the areas where the flaps are sealed. The thermal imaging camera is providing a measurement of the glue temperature and location, through the carton material. The colour camera checks that the flaps have been properly formed and that the carton is of the correct shape. If HotSpot identifies a failure from either camera, the system can provide a digital output to the production line.
