Description

Technical Field

[0001] The invention relates to the technical field of egg quality detection, in particular to an egg quality detection system. Background Art

[0002] Egg appearance detection includes broken eggs and cracked eggs. Broken eggs are eggs with collapsed nests (depression) and eggs with holes (egg liquid flowing out), and cracked eggs are eggs with visible cracks. In the prior art, the detection of egg appearance is achieved by setting an irradiation light source below the eggs and a visual inspection system above the eggs. However, the prior art currently has poor results in collecting crack patterns on eggs; and it is unable to overcome the light leakage caused by the absence of eggs at a certain position of the egg conveyor roller.

[0003] The light-transmitting surfaces of the irradiation light sources used in the prior art are basically flat surfaces. The egg liquid from collapsed eggs or eggs with holes or cracks is easy to drip and splash downwards and remain on the flat light-transmitting surfaces, causing serious dirtiness and affecting the fill light.

[0004] The irradiation light source used in the prior art is screwed and locked on the frame below the eggs. Therefore, when the irradiation light source needs to be repaired, the staff needs to drill under the machine or remove the side panel of the machine to perform the maintenance work, which is very troublesome and the structural design is not reasonable.

[0005] In the prior art, the camera setting of the visual inspection system is unreasonable. The camera generally captures images vertically downward, which easily results in the inability to obtain a complete image of the egg, causing some eggs that are not fully inspected to not be detected.
