The invention discloses an inner blank chip feeding device for a signal connector. The device comprises a frame, wherein one side of the frame is configured as a feeding end, and the other side of the frame is configured as a discharging end; a lifting cylinder is fixedly arranged at the top of the frame and is connected with a lifting platform; a rotary cylinder is fixedly arranged at the middle of the bottom of the lifting platform and is connected with a rotary connecting plate; the two ends of the rotary connecting plate are both provided with a suction nozzle component; each suction nozzle component is arranged on an elastic returning component; each elastic returning component is fixedly arranged at one side of the rotary connecting plate; a downwards-pressing mechanism is arranged at one side, positioned at the discharging end, of the lifting platform; the downwards-pressing mechanism is used for tightly pressing each suction nozzle component so that the suction nozzle component can move downwards; a displacement mechanism is arranged at the bottom of one side, positioned at the feeding end, of the frame. The inner blank chip feeding device disclosed by the invention has the advantages of implementing automatic feeding and discharging, realizing an automation function, liberating the labor force and being high in precision and high in speed.
