Aiming at the disadvantages of the poor working environment and low sorting efficiency of the artificial gangue sorting, a parallel SCARA type gangue sorting robot was designed. The three-dimensional modeling was carried out, and the composition structure and working principle of each part were described. The solution method of symmetrical and simplified model was adopted to carry out the finite element analysis and strength check of the sorting robot.According to the geometric characteristics of the sorting robot, the forward and inverse kinematics were solved by using analytic method.The results show that the design can meet the requirements of gangue sorting with a particle size of 300~600 mm, with high safety factor and reliability, and can be applied in gangue sorting and other related industries.
