Method for dielectrically heating an adhesive

摘要

A method of heating an adhesive including the steps of placing a dielectrically heatable adhesive 24 between first and second members 18, 26. A high frequency electric field is applied between the first and second electrodes 12, 14 sufficient to dielectrically heat the adhesive. The surface temperature of the first member is measured in the vicinity near the adhesive. The electric field is removed after the measured temperature reaches a predefined amount. The invention anticipates measuring the infrared radiation emitted from the surface of the first member and is measured with an infrared detector 30. A controller 34 receives the measured infrared radiation and compares it to stored values. After the measured temperature reaches a predefined value or values, the controller sends a signal to an RF generator 16 to remove the electric fields.
