In this paper,a kind of automatic loading and unloading manipulator for precious metal jewelry processing is designed,and the simulation experiment is carried out.The hardware part of the device is com-posed of a mechanical arm and a manipulator claw,and a progressive motor is used as a driving device.In the software part,the ATmega88 master chip is used as the lower computer,and the serial communication protocol is used to communicate with the upper computer in real time.Mablab/Simulink software was used to build the model and simulate it.The results show that the clamping range of mechanical finger is between 10～30 mm,which can meet the clamping requirements of most precious metal jewelry blanks.The model can automatically complete the loading and unloading operation according to the planned path,which has a high degree of automation and improves the processing efficiency.
