Hot glues are solid substances which, after heating to the working temperature, melt and are used as liquid glue. When connecting sealed surfaces, the areas are sealed before the glue cools and hardens. Thermoinspector is used at the site of the production line. As a result of measuring the temperature, it is possible to determine if there is the required amount of glue on the sealed part and if each application of the glue is in the correct position and if the glue is at a temperature to ensure top quality sealing of the individual parts. If the temperature or the position of the glue does not correspond to requirements, the product will not fulfil the requirements of the manufacturer and the manufacturer would face the risk of an increased number of complaints and the loss of their good name. This can be prevented by the application of ThermoInspector.
For example, in one application of ThermoInspector during the production of components for the automotive industry, the measured temperature was only at the lower limit. This is defined with respect to the plasticity of the glue at 50°C. The temperature is checked in eight rectangular areas of interest in which the maximum temperature is evaluated, which must not fall below the stated limit. In the case that the required temperature is not achieved, the system signals a defect on the monitor and the defective items are excluded from the next phase of the manufacturing process.
The Workswell ThermoInspector system has been successfully used for this application since the summer of 2014 and as a result, the user can produce consistently high quality products.
