EyeVision HotGlue – Thermal Imaging Inspection for adhesive points

The HotGlue Inspector inspects, 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). Inspects adhesive joints for presence and temperature The cameras can be arranged so that the sides with the adhesive points are in the field of view of the thermal imaging camera. The EyeVision HotGlue Inspector checks if the glue has been applied to all adhesive joints and if the temperature of the glue at the joint is inside the threshold. Therefore it si guaranteed that the cartons are glued together at the joints and are not falling apart and causing the bottles to tumble out of the box during transportation, neither during the transportation from production site to the shop nor when transported by a customer. If a glue is missing at an adhesive joint, because either a nozzle is blocked or the glue has not been fed, then this is detected automatically. It will be also detected, if the temperature of the glue is not hot enough. This can happen, when the heating is defect or due to a delay in the plant. In case only one ore more adhesive joints are showing a temperature that is not hot enough, then the error can be matched to the respective glueing device. Therefore it can be easily determined, where a repair is necessary. And when all adhesive joints show a temperature which is too low then the carton can be ejected completely. EyeVision HotGlue Inspection of adhesive joints Trackerboard and Interface selection with EyeVision HotGlue The EyeVision HotGlue system has digital interfaces to allow for an autonomous operation on a plant. This can be carried out via a Profinet interface in the EyeVision software. And an integration into an existing PLS is therefore very easily achieved.
