Dual-platform board feeding mechanism of surface mounted technology-based machine

Provided by the utility model is a dual-platform board feeding mechanism of a surface mounted technology (SMT)-based machine. The dual-platform board feeding mechanism comprises a left independent board supply platform, a right independent board supply platform, lead screws, sliding blocks and servo motors, wherein left independent board supply platform and the right independent board supply platform are installed on a body of an SMT-based machine. The left independent or interactive and selective circuit board supply platform and the right independent or interactive and selective circuit board supply platform feed circuit boards into the SMT-based machine to carry out mounting. When the left board supply platform carries out mounting on the circuit board, the operator can place the circuit board on the right board supply platform well at the moment; and after the mounting is completed, the mounted circuit board at the left is sent out and simultaneously, the right board supply platform feeds a to-be-mounted
