9. The dispensing method of the wafer wafer transfer pad rapid prototyping dispensing machine according to any one of claims 1-8, characterized in that, The dispensing method comprises the following steps: S100: First, fill the A glue stirring storage barrel and the B glue stirring storage barrel with epoxy resin glue respectively, set the temperature in the barrels to 25 degrees, and stir uniformly. Adjust the viscosity of the glue in the A glue stirring storage barrel and the B glue stirring storage barrel as needed. Adjust the mixing ratio of the A glue stirring storage barrel and the B glue stirring storage barrel by adjusting the flow control valve at the lower end of the A glue stirring storage barrel and the B glue stirring storage barrel. S200: Adjust the glue output of the dispensing needle nozzle through the dispensing control valve, and test and calibrate the glue output of the dispensing needle nozzle through the balance. S300: The loading platform is divided into four sections, each of which can place 32 products to be dispensed, a total of 128 products to be dispensed. Place the products to be dispensed on the first section at the front end of the loading platform. Press the control button on the front end wall of the control box manually. Dispense the products to be dispensed on the first section at the front end of the loading platform one by one according to the set program through the dispensing mechanism until all the products are dispensed. S400: When the dispensing of the products to be dispensed on the first section is completed, the dispensing needle nozzle protection baffle slides to the lower side of the dispensing needle nozzle to protect the dispensing needle nozzle. Start the plasma rotating nozzle and clean the products on the first section at the front end of the loading platform one by one according to the set program through the plasma rotating nozzle. S500: while dispensing, the products to be dispensed are placed on the second section, the third section and the fourth section on the loading platform in the order from front to back, and the dispensing mechanism and the plasma rotating nozzle dispense and clean the products to be dispensed on the second section, the third section and the fourth section in the order from front to back, while the products that have been dispensed and cleaned are taken off and new products to be dispensed are placed, and the process is repeated to realize uninterrupted dispensing.
