Bird egg dark fringe detection device

The invention relates to the technical field of bird egg incubation, in particular to a bird egg dark fringe detection device. The bird egg dark fringe detection device comprises a case, a suction nozzle, a lifting driving mechanism and an image acquisition device; the suction nozzle is used for adsorbing a to-be-detected bird egg, and a lamp with the illumination direction towards an opening partof the suction nozzle is arranged in the suction nozzle; the lifting driving mechanism is fixed inside the case and used for driving the suction nozzle to do lifting motion; and the image acquisitiondevice is fixed inside the case and used for acquiring an image of the bird egg adsorbed by the suction nozzle. The device provided by the invention can replace manual illumination on the bird egg, labor intensity of a worker is reduced, hatching egg detection speed and accuracy are improved, and the device takes a hatching egg tray in the actual production as the basis, so that egg damage can beeffectively reduced, and t
