SimplePnP is an open hardware Cartesian pick-and-place machine. It includes two main components: the head and the table.
The head grabs electronic components meant to be installed on a PCB. It relies on a hollow shaft stepper motor to rotate the parts and allow a DC vacuum pump to hold them with different sized nozzles. It uses a camera to help locate features and components.
The table is meant to position the head in the correct spot to hold and release each component. It is a gantry style system built from aluminum extrusion and uses linear rails, stepper motors and timing belts to perform motion.
A computer running OpenPnP serves as the machine's brain, sending the appropriate commands to a pair of GRBL motion controllers that handle the operations needed to perform PCB assembly.
