Abstract
The shielding effectiveness of industrial robot servo control cabinet in the electromagnetic radiation environment is rarely studied. In this paper, the heat dissipation structure of cabinet for welding robot is analyzed and researched in the electromagnetic environment.
The radiation interference source, electromagnetic frequency band, intensity and the interference path of electromagnetic environment are analyzed in the industrial environment of welding robot. Based on the transmission line theory of Robinson algorithm, the physical model and equivalent circuit model of the shielding cavity for the control cabinet are constructed to calculate the shielding effectiveness for the heat dissipation structure of control cabinet, such as louver type, hole array and internal partition. We have carried out the simulation of heat dissipation structure for cabinet which is mentioned in the previous sentence. The result shows that when the area of the heat dissipation structure is equal, the design of cabinet can take this shielding scheme that is arranged with the hole array and the internal partition in heat dissipation structure, which has relatively the best shielding effectiveness.
The results of this paper provide theoretical reference for the engineering design of welding robot servo control cabinet, and the subsequent research on electromagnetic field and thermal field integration design is needed.
