Chip mounting device

The invention discloses a chip mounting device. The chip mounting device comprises a main shaft mechanism; a suction nozzle; the first spring is arranged between the suction nozzle and the main shaft mechanism; the gas flow path is formed in the main shaft mechanism and the suction nozzle, and a first suction opening is formed in the lower end of the suction nozzle; the annular component is provided with an annular inner cavity and an annular bottom surface, the lower end of the suction nozzle penetrates through a center hole of the annular component and penetrates through the annular bottom surface, so that the annular bottom surface surrounds the first suction port to form a pickup surface, a radial through vent hole is formed in the shaft section, penetrating through the annular component, of the suction nozzle, and the vent hole is used for enabling the annular inner cavity to be communicated with the gas flow path; a second suction port communicated with the annular inner cavity is formed in the area whe
