[0049] Working principle and process:

[0050] When using the equipment in this solution:

[0051] 1. The rotor and impeller can be loaded on the material placement tray by manipulator or manual method;

[0052] 2. Then the material placement tray moves on the transport track to the airtight detection mechanism, the pallet transfer assembly double-speed chain structure stops, and at the same time, the ejection cylinder lifts the material placement tray so that the top surface of the material placement tray contacts the horizontal section of the limit buckle to achieve the positioning of the material placement tray in the vertical direction. At the same time, the horizontal positioning cylinder contacts one side of the material placement tray so that the side surface of the material placement tray contacts the vertical section of the limit buckle to achieve the positioning of the material placement tray in the horizontal direction;

[0053] 3. The airtightness detection mechanism will then move the rotor and conduct a test. After the test, the rotor will be placed back on the material placement tray and the test results will be recorded;

[0054] 4. Invert step 2 so that the material placement tray falls back to the double-speed chain structure, and the unqualified products are moved to the NG unloading assembly, and step 2 is repeated. Then the NG unloading mechanism removes the unqualified products; the qualified products are moved to the material transfer assembly, and step 2 is repeated. The material transfer assembly transfers the rotor and impeller to the rotor placement tooling and the impeller placement tooling respectively;

[0055] 5. The impeller pressure head is pre-tightened, and then the press descends to press the impeller and the rotor. At this time, the distance sensor detects the impeller pressing distance. If it exceeds the standard range, it will be recorded and unloaded through the NG unloading component;

[0056] 6. During step 5, the vibration plate loads the bearing, the cutting assembly cuts the bearing, and then the bearing transfer assembly absorbs a single bearing. When the impeller is pressed and qualified, the second horizontal drive assembly drives the impeller pressure head to the bottom of the press. At the same time, the second vertical drive assembly drives the impeller pressure head to pre-tighten, and then the press presses down to complete the entire process.
