Design and simulation analysis of physical heat dissipation structure for welding robot controller

In order to understand the physical heat dissipation structure of welding robot controllers, the author proposes a research based on the design and simulation analysis of the physical heat dissipation structure of welding robot controllers. The author first analyzed that the design of welding heating system is the key to the research of welding robot heating technology, which is divided into the design of induction heating system temperature control circuit and temperature control program. The induction heating system is closely related to power electronics technology, with inverter design and soft switching technology being the focus and difficulty of this chapter. Secondly, using modular design methods, an induction heating system with a frequency of 450KHz and a power of 100 W is designed. This part is connected through an optocoupler and an induction heating system for power regulation and temperature control. Starting from designing the minimum system of a microcontroller, through keyboard input, temperature signal processing, analog-to-digital conversion, and finally to digital tube display output, the design of each module of the temperature control circuit was completed. Finally, in order to verify the effectiveness of the design, actual heat dissipation testing is required. By establishing an appropriate testing environment in the laboratory, the temperature changes and heat dissipation efficiency of the controller under different working conditions can be measured. Based on the actual test results, further adjustments and improvements can be made to the design to meet the heat dissipation needs of the welding robot.
