Abstract
This paper proposes a heat source analysis method to calculate the heat loss generated by SCARA robots during operation. The heat dissipation power of the robot is determined by empirical formula and robot energy consumption. The thermal model of SCARA robots was established by using the finite element method in COMSOL, and the steady-state temperature and heat dissipation path of SCARA robots were obtained by solving the finite element model. It was concluded that the temperature at axis Jl of a SCARA robot was the highest, and the temperature diffused in the center of axis Jl. The effect of surface convection velocity on the steady-state temperature of SCARA robots is studied. The results show that the increase of surface convection velocity can effectively reduce the temperature of the robot at high temperature.
