The vibrating collecting plate continuously vibrates, so that the metal powder does not adhere to the vibrating collecting plate and falls into the collecting tank, thereby making the quality of the generated metal powder more stable. 2. When the diverter scraper rotates clockwise in the centrifugal tank, the first limiting teeth and the second limiting teeth remain stationary, so that the diverter scraper can scrape off the metal powder melt adhering to the inner wall of the centrifugal tank. At the same time, the heat pipe and the heater are used to prevent the metal powder melt from remaining in the centrifugal tank and affecting the subsequent metal powder generation work; 3. After the metal powder is discharged, it is moved into the processing tank through the cleaning and collecting component. The cleaning and collecting component cleans the metal powder attached to the inner wall of the processing tank and makes the metal powder fall to the bottom of the processing tank and be discharged again, so that all the metal powder can be discharged to the outside without remaining inside the processing tank.

The quality of the generated metal powder is relatively stable, and the molten metal powder in the centrifugal component can be scraped off to avoid the molten metal powder remaining in the centrifugal component and affecting subsequent production. At the same time, the residual metal powder in the tank can be cleaned so that the metal powder can be completely discharged to the outside with less residue. BRIEF DESCRIPTION OF THE DRAWINGS

10. A method for preparing metal powder for making solder paste, characterized in that: The following steps are involved: S1: The metal powder melt for preparing solder paste is introduced into the centrifugal component (300) through the feeding component (200), the flow-dividing and scraping component (400) divides the metal powder melt into a plurality of parts, the centrifugal component (300) and the flow-dividing and scraping component (400) rotate counterclockwise together, and the centrifugal component (300) throws the metal powder melt out through the atomizing hole (351), thereby performing atomization and powder making; S2: After atomization and powdering, the metal powder falls onto the vibrating collection assembly (500), and the vibrating collection assembly (500) continuously vibrates, causing the metal powder to shake along the inclined ramp and fall into the bottom of the processing tank (100), and be discharged from the discharge port (110); S3: rotating the centrifugal assembly (300) clockwise and keeping the flow-dividing and scraping assembly (400) stationary, so that the flow-dividing and scraping assembly (400) scrapes away the metal powder melt adhered to the centrifugal assembly (300), and then rotating the centrifugal assembly (300) counterclockwise to throw out the remaining metal powder melt; S4: The cleaning and collecting component (600) is moved into the processing tank (100), and the cleaning and collecting component (600) rotates at the bottom end of the processing tank (100) to clean the metal powder attached to the inner wall of the processing tank (100), so that the metal powder falls off and is discharged from the discharge port (110).
