The water baffle installation mechanism 34 includes a water baffle feed plate 341 and a water baffle installation clamp 342.

[0036] The rotor bearing press-fitting, water baffle ring installation, and connector press-fitting process involves the rotor being transported by a robot to the upper and lower rotor bearing press-fitting stations of the rotor bearing press 33. The rotor bearing press 33 completes the press-fitting of the upper and lower rotor bearings. Then, the servo first rotor transfer mechanism 37 transports the rotor bearing assembly to the water baffle ring installation station, where the water baffle ring installation mechanism 34 installs the water baffle ring onto the shaft of the rotor bearing assembly.

The back cover press 43 presses the back cover fitted on the stator onto the stator through the back cover pressing mold 42.

[0038] During the press-fitting of the rear cover, the operator removes the rear cover from the rear cover material box and places it onto the rotor shaft. At the same time, the operator screws the three bolts used to lock the rear cover onto the stator housing (the bolts are only screwed in 2-3 turns, which cannot be tightened manually). The workpiece positioning and lifting press 41 lifts the rotor shaft. A servo-controlled rear cover press 43 (maximum pressure 1 ton) presses the rear cover.

The stationary ring press 66 presses the stationary ring into the rotor shaft.

[0042] During the pressing of the stationary ring, the stationary ring is first placed manually into the stationary ring tray 64.

The workpiece positioning and lifting press 71 is connected to the line body 9. When the workpiece positioning and lifting press 71 rises, it lifts the motor body on the line body 9. The impeller press 73 is located above the line body 9. The impeller press 73 presses the impeller fitted on the motor body onto the rotor shaft of the motor body through the impeller pressing mold 72.

[0044] Before the impeller pressing station 7, the impeller, rotating ring and other parts are manually put onto the rotor shaft.

The carrier 93 is connected to the double-speed chain 92 and has positioning holes for placing water pump products. The head lift 94 and the tail lift 95 are located at the loading end and unloading end of the production line support 91, respectively.

[0048] Line 9 is mainly used to convey carriers 93. A material bar drive motor moves a double-speed chain 92, synchronously moving the carriers 93 on the chain. Water pumps are placed in corresponding positioning holes on the carriers 93. Line 9 includes an upper conveyor line and a lower return line, enabling the circulation of carriers 93. The line head lift 94 and line tail lift 95 can be adjusted to their heights relative to the loading and unloading ends of line 9, thus adapting to different loading and unloading height requirements.

The stationary ring tray cylinder transfers the stationary ring tray to the pick-up station via the tray feeding plate. The stationary ring three-axis module transfers the stationary ring from the pick-up station to the rotor shaft of the production line via the stationary ring pick-and-place gripper. The stationary ring press presses the stationary ring into the rotor shaft.

8. The semi-automatic water pump assembly line production equipment according to claim 1, characterized in that, The impeller pressing station includes a workpiece positioning and lifting press and an impeller press equipped with an impeller pressing mold. The workpiece positioning and lifting press is connected to the production line. When the workpiece positioning and lifting press rises, it lifts the motor body on the production line. The impeller press is located above the production line. The impeller press uses the impeller pressing mold to press the impeller fitted on the motor body onto the rotor shaft of the motor body.

9. The semi-automatic water pump assembly line production equipment according to claim 1, characterized in that, The production line includes a production line support, a double-speed chain, a carrier, a head lift, a tail lift, and a chain drive. The chain drive and the double-speed chain are mounted on the production line support. The double-speed chain is connected to the output end of the chain drive. The double-speed chain forms an upper conveyor line and a lower return line on the production line support. The carrier is connected to the double-speed chain and has positioning holes for placing water pump products. The head lift and the tail lift are located at the loading end and unloading end of the production line support, respectively.

10. The semi-automatic water pump assembly line production equipment according to claim 1, characterized in that, It also includes RFID readers. The stator loading station, wave spring installation and oiling station, rotor component pressing station, rear cover pressing station, screw fastening station, stationary ring pressing station, impeller pressing station, electrical testing station, and gas testing station are all equipped with RFID readers.
