Device for charging metal particles

The invention relates to the field of electronic device manufacturing, and particularly discloses a device for charging metal particles. The device comprises a storage unit, a high-frequency oscillation unit, an insulation unit, a charge generating unit, an auxiliary drive unit and a control unit, wherein the storage unit, the high-frequency oscillation unit, the insulation unit, the charge generating unit and the auxiliary drive unit are sequentially connected, and the control unit controls the storage unit, the high-frequency oscillation unit, the charge generating unit and the auxiliary drive unit. According to the device, liquid metal is crushed and divided into submicroscopic particles independent from one another, the submicroscopic particles are charged with appropriate like charges by means of the charge generating unit, the submicroscopic particles will repel one another, and therefore the metal particles can be evenly and tidily arranged and be attracted to the surfaces of materials to be sprayed or
