Abstract

The invention discloses an online visual inspection device and an online visual inspection method for cracks on the surface of poultry eggs, relating to the technical field of the poultry egg processing and grading. The online visual inspection device is characterized in that an opaque chamber (2) is arranged above a conveyer belt (1), and an industrial camera (3) is arranged at the center of the top part of the opaque chamber (2); a light source (6) is arranged under the conveyer belt (1) and is transmitted to be positioned on the poultry egg (8) on the conveyer belt (1) through a gap of the conveyer belt (1); a photoelectric switch (7) is arranged at the inner side of the opaque chamber (2), the photoelectric switch (7) is connected with a single-chip microcomputer (5) by a data line, and the single-chip microcomputer (5) and the industrial camera (3) are connected with a computer 4 by data lines. According to the online visual inspection device and the online visual inspection method, the cracks on the surface of the poultry egg can be inspected by machine vision, and the online visual inspection device has good adaptability to the application environment; the single industrial camera is used for shooting the poultry egg in a multi-overturning-angle manner, the detection range is wide, the equipment cost is low, and high-efficiency and high-intelligence nondestructive examination can be achieved; and the online visual inspection device and the online visual inspection method have good application and promotion prospect.

Description

technical field [0001] The invention relates to the technical field of poultry egg processing and grading, in particular to an online visual inspection device and method for cracks on the surface of poultry eggs. Background technique [0002] Poultry eggs have very high nutritional value, rich in protein, fat, multivitamins and trace elements, and are one of the important foods in people's daily life. Because the eggshell is thin, it is fragile during transportation. Once cracks appear, bacteria can easily invade the egg, causing corruption and deterioration inside the egg. Such eggs cannot be processed and eaten, and need to be removed in time. [0003] At present, some scholars have conducted research on the detection of cracks on the surface of poultry eggs. Tu Kang (a method and device for detecting the surface quality of poultry eggs, CN200510134902.5) uses the sound signal generated by the impact of the elastic percussion rod on the surface of the eggshell and the ima...
