There are some problems about the current domestic desktop pick-and-place machine, such as the lack of vision system, the shortage of pick-and-place precision and the high cost. In order to solve these problems, the paper studied on the accurate machine system, the vision positioning system, the motion control system and the operation software system. It designed a high-precision machine plat-form driven by the closed-loop control of stepper motor, and accomplished the mechanism to accurately pick and place electronic components of 0402 and CEFP package outline and the automatic feeding mech-anism. To achieve the five-axis motion control, the self-proprietary multi-core asynchronous programma-ble automation controller was adopted. It applied the Freeman chain code to accomplish the critical tech-nology of the contour extraction on the vision positioning system,and developed the PC operation software system. The test results showed that it could achieve the goal of the high-precision picking and placing.
