The invention discloses a fluoride rubber vacuum suction nozzle with an arc-shaped working surface. The fluoride rubber vacuum suction nozzle with the arc-shaped working surface is arranged on a mounting rod with a vacuum ventilation pipeline therein, and is a main component for finishing automation of chip packaging equipment. The working surface of the vacuum suction nozzle is designed into the arc-shaped working surface with a certain radian of 10-15 degrees; the length and the width of the working surface are 3-5 microns greater than the single-side size of a corresponding chip; and the working surface does not directly contact the surface of the chip and only contacts the edges of two ends of the chip when used, so that a direct contact of the working surface of a traditional vacuum suction nozzle and the surface of the adsorbed chip is avoided; and the effects are achieved as follows: (1) a suction nozzle mark is not left on the surface of the chip; (2) the surface of the chip is not scratched; (3) a circuit on the surface of the chip is not damaged; and (4) and the suck-back phenomenon of the chip is avoided.
