Inside the positioning sleeve 322 of the fixture 32, the HSK positioning carrier 32, equipped with HSK, is moved to the PCB board positioning carrier 31 directly below it by the sliding lifting assembly 33. The first lifting cylinder 334 drives the HSK positioning carrier 32 to rise and pass through the through hole 317, so that the HSK abuts against and fits the mounting surface of the PCB board. Finally, the screw suction nozzle 68 is driven by the pick-and-place robot to pick up the screw from the screw feeder 7 and move it to the PCB board positioning carrier 31 directly above it.
