Problems solved by technology

Due to the limited size of the cavity, this type of microwave heating equipment can only be used to process small workpieces, and it is powerless for ultra-long and ultra-wide workpieces, such as: bonding of body interior materials, drying of body paint, etc.
In addition, in the case of automated assembly line production, in the bonding and gluing process of various product structure components, the process requirements are often limited to the rapid drying and curing of materials at a few key points, rather than the overall drying and curing of materials. The whole component is put into a microwave heating furnace for heat treatment, the efficiency is obviously too low, the drying and curing time is too long, and it is difficult to meet the production process requirements

Embodiment 1

[0033] Such as Figure 1-2 As shown, the present application provides a frequency conversion microwave heating device, including a robot, a first controller, an actuator, a microwave antenna 13 , a power supply and several cables 14 .

[0034] The robot includes a base 111 , a body 112 and an operating arm 113 . During use, the power supply and the first controller are packaged in a small electrical cabinet 20 , fixedly placed next to the base 111 of the robot, and connected to the actuator through the cable 14 . The actuator is held by the robot, and the antenna is installed at the end of the actuator. When working, the area in front of the antenna will generate a high-power electromagnetic field.

[0035]The actuator includes a coupler, a housing 121, a microwave attenuator, a variable frequency microwave generator and a power amplifier. One end of the casing 121 is connected to the operating arm 113 of the robot, and the other end of the casing 121 is connected to the one...

Embodiment 2

[0059] Distributed multi-antenna variable frequency microwave (VFM) heat gun equipment. The technical index is similar to that of Embodiment 1, except that the form of the antenna is changed to 2 antennas, which are distributed on the custom-made fixtures. The connection between the antenna and the actuator is through a flexible waveguide.

[0060] Still taking car body manufacturing as an example, in the bonding process of large-scale interior components, only a few key positions on the glued area (such as: one head and one tail) need to be quickly connected and fixed to ensure that the assembled components can be integrated in an overall form. Grabbed by the robot to start the next process, instead of requiring the entire glued area to complete the overall drying and curing in the current process. The process design of the above usage scenarios, two large interior components bonded to each other, are clamped and pressed by special fixtures after the glued surface is glued. ...

Abstract

The invention provides a variable-frequency microwave heating device. The variable-frequency microwave heating device comprises a robot, a first controller, an actuator, one or more microwave antennas, a power supply and a plurality of cables, and the actuator comprises a shell, a microwave attenuator, a frequency conversion microwave generator and a power amplifier. After the technical scheme is adopted, microwave energy generated by the variable-frequency microwave heating device is concentrated in a small-range point-shaped area of the microwave antenna end, a microwave electromagnetic field environment with high power and high energy density can be instantly generated in a small-range space, fixed-point and point-by-point microwave heating is carried out on a material, and drying and curing can be completed within an extremely short time. Besides, the variable-frequency microwave heating device has the advantages of being small in size, light in weight, capable of being conveniently held and operated by a robot and the like, the use requirement for automatic batch production of industrial products is completely met, and by means of the device, the production process innovation that microwave heat treatment is converted into online operation from offline operation can be achieved.

Description

technical field [0001] The invention relates to the technical field of industrial automation manufacturing, in particular to heat treatment for rapidly heating, drying and curing materials in the industrial manufacturing link. Background technique [0002] Microwave heating means that when the material is in a microwave environment, dipoles will be formed inside the material or the existing dipoles will be rearranged, and will swing at a high frequency of hundreds of millions of times per second with the high-frequency alternating electromagnetic field. The material molecules are constantly rearranged under the action of the electromagnetic field. In the process, it is necessary to overcome the obstacles of the original thermal motion and molecular force between the molecules, thus producing a friction phenomenon similar to the mutual motion of macroscopic objects. Therefore, the microwave heating process can be simply summarized as the process in which the energy of the ele...
