Abstract

The invention provides a microwave automatic heating device. The microwave automatic heating device comprises a microwave generator, a microwave cavity, a control system, a microwave power control module and a microwave local shielding part, wherein the microwave generator transmits microwaves into the microwave cavity; the microwave cavity is used for holding a light-absorbing material; the microwave local shielding part is positioned in the microwave cavity, and is used for covering the outer surface of the light-absorbing material; the microwave local shielding part consists of a microwave shielding area and a microwave penetration area; the microwave penetration area comprises one or more apertures in order that the microwaves in the microwave cavity can enter the light-absorbing material from the aperture(s) in order to be absorbed; the control system arranged outside the microwave cavity is used for automatically adjusting the turn-on/off and/or power of the microwave generator by automatically controlling the microwave power control module. By adopting the microwave automatic heating device provided by the invention in conjunction with a computer automatic control technology, fixed-point and/or directional heating under automatic control can be performed on the light-absorbing material.

Description

technical field [0001] The invention relates to the field of microwaves, in particular to a microwave automatic heating device and method. Background technique [0002] Microwave has the advantages of selective heating of certain materials, fast heating speed, uniform heating, strong penetration, and small thermal inertia. Applying microwave technology to the field of composite material curing can significantly reduce curing time, reduce production costs, and obtain Excellent product performance, with great development potential. [0003] A lot of research has been carried out in the field of composite material curing at home and abroad, and fruitful results have been obtained. However, these studies have a common feature, the composite materials are all directly exposed to the microwave field to complete the curing. For example, Chinese patent application CN201410295387 provides a method for uniform temperature distribution of microwave-pressure-cured composite materials ...
