PCB feeding device

The utility model discloses a PCB (printed circuit board) loading device, which belongs to the technical field of PCBs and comprises a bottom plate, a suction nozzle assembly is arranged above the bottom plate, and the bottom plate is connected with the suction nozzle assembly through a rotating device. By arranging the rotating device, a worker can rotate and adjust the positions of the suction nozzle assembly and the PCB on the suction nozzle assembly by operating the motor when needed, so that the selectable positions of the PCB when the PCB is put down are expanded, the working requirements under different conditions are better met, and the working capacity of the device is further improved; according to the utility model, through the arrangement of the limiting placement device, a worker can limit the PCB placed on the placement table to a certain extent through the limiting frame when needed, so that the possibility that the PCB falls off due to collision, vibration and the like when the PCB is placed o
