Glue dot inspection

EVT HotGlue Inspector

The HotGlue Inspector checks, if the adhesive points between cardboard surfaces of boxes are present and hot enough to glue the cardboard box together. With up to 60 boxes per second (which amounts to 3600 boxes per minute). Available camera resolutions are 291 x 120 and 640 x 480 Pixel.

The system is based on the EyeVision software and is easily adapted to your applications. The hardware includes the EmSys computing unit and a thermal imaging camera of the supported makers such as e.g. Optris, Flir, etc.


Inspects adhesive joints for temperature

If a glue is missing at an adhesive joint or if the temperature of the glue is not hot enough, then this is detected automatically. Then the error can be matched to the respective glueing device and can be immediately repaired. The carton can also be rejected completely in case all the adhesive joints are missing or the temperature is too low.

 Interfaces and protocols

The system can communicate via the hardware interfaces with a tracker-system as well as with SCADA or a PLC. With the communication protocols such as Profinet, Modbus, TCP/IP & UDP the system can communicate with the machine.

Graphical set up of inspection points

The setup of the test facility is carried out completely graphically. The threshold for each adhesive joint can be either specified globally, for groups or for each adhesive joint separately. The integration of the system into a plant is supported by the embedded mode. This means that the system has a protocol implemented, which allows the setup as well as the operation from any desired remote system.

Multi-Camera Support

With EVT HotGlue several thermal imaging cameras can be used. To inspect all four sides of a container for example four cameras can be used.
