Description

Technical Field

[0001] The utility model relates to the technical field of egg crack recognition, in particular to an egg crack recognition device based on machine vision. Background Art

[0002] In large-scale laying hen breeding bases, a large number of eggs are produced every day. Most of the eggs are collected by egg collecting equipment, and the eggs are transported out of the chicken cages by conveying devices. During the egg collection and transportation process, it is inevitable that the eggs will be slightly bumped, causing the eggs to crack, affecting the quality of the eggs and the storage time. During the storage of eggs, the intact eggshell has a protective effect on the inside of the egg, which increases the storage time of the egg. When the egg cracks, the egg liquid is in direct contact with the outside world, and it deteriorates quickly, which is not conducive to storage. Therefore, it is necessary to sort out the cracked eggs in time; in the process of egg inspection with existing devices, the eggs cannot be rotated, which is not conducive to multi-angle inspection of the eggshell;

[0003] After searching, the prior art is disclosed in the authorization announcement number CN220419190U, which discloses an egg crack detection device, including a device body, wherein a conveyor belt is fixed transversely inside the device body. During use, the egg crack detection device is used to place eggs into a holding box in sequence, and then place the holding box on the top of the conveyor belt, which drives the holding box to be transported into the device body. At the same time, the output end of the driving motor can be controlled to drive the disc to rotate, and the rotation of the disc can simultaneously drive the rotation of multiple groups of soft brushes at the bottom. When the holding box reaches the bottom of the disc, the rotating multiple groups of soft brushes can clean the dust and debris on the outside of the eggs placed on the holding box, thereby reducing the adhesion of debris on the outside of the eggs and reducing light obstruction, making it easier to detect the eggs. This solves the problem of inconvenient auxiliary cleaning of debris on the outside of the eggs.

[0004] The above patent cannot rotate the egg during use, resulting in a fixed egg detection angle and an inability to guarantee crack detection efficiency; therefore, we need to propose an egg crack recognition device based on machine vision. Utility Model Content
