Use a trolley to transport the impeller rotor tray with the impeller rotor to the second station, transport the stator base plate tray with the stator base plate to the third station, transport the pump casing tray with the pump casing to the fourth station, and transport the finished product tray to the sixth station, and prepare several carrying plates at the same time; S2, placing the carrier plate at the starting position of the head end of the upper U-shaped conveyor belt, and starting the entire production line so that the carrier plate is conveyed on the upper U-shaped conveyor belt toward the tail end; S3, when the carrier plate reaches the first station, the pneumatic limit device stops the plate from moving forward, and the worker at the station presses the shaft assembly on the carrier plate. After the press-fitting of the shaft assembly is completed, the limit button is pressed to lower the pneumatic limit device, so that the carrier plate continues to be transported through the pneumatic limit device. When the carrier plate passes through, the pneumatic limit device automatically resets to continue the blocking work; S4, when the carrier plate reaches the second station, it is blocked by the pneumatic limit device to stop moving forward. The worker at this station takes the impeller rotor from the impeller rotor tray and assembles the shaft assembly on the carrier plate to form an impeller rotor assembly.
