Embodiment Construction

[0046] A method for recognizing and separating loose yolk eggs based on machine vision on a chain egg beater, the steps of which are as follows:

[0047] A. Image collection: The egg container 4 installed on the egg container mounting beam 2 moves forward with the production line driven by the transmission chain 1. When the separation pin 4d passes under the proximity switch 5, the proximity switch senses a row of container The egg container 4 is passing through the proximity switch, which will send a signal to trigger the industrial camera 14 to take pictures of the egg white contained in the egg container 4 and the egg white bucket 4a and the egg yolk contained in the egg yolk cup 4b on the production line, and the captured image data will be sent to computer;

[0048] B. Image processing: when the industrial camera 14 is triggered to shoot, there is always an egg holder installation beam 2 at a fixed position in the camera field of view, and the number N of egg holders 4 in...

Abstract

The invention discloses a method and a device for identification and separation of yolk-dispersed eggs based on machine vision. The method comprises steps of image acquisition, image processing and control of action execution of a cylinder. The device comprises a industrial camera, an LED light source, a cylinder and egg containers. Fixing holes for a LED light source mounting beam are drilled in a horizontal crosspiece. A proximity switch mounting rack, a short standing frame, the horizontal crosspiece and a long standing frame are tightly fixed together through welding. The cylinder mounting beam is tightly fixed on the short standing frame through bolts. The LED light source mounting beam is mounted on the horizontal crosspiece through bolts. Irradiation angles can be adjusted according to requirements. The LED light source is mounted on the LED light source mounting beam. A camera mounting beam is tightly fixed on the long standing frame through bolts. A camera mounting holder is tightly fixed in the middle of the camera mounting beam through bolts. The camera mounting holder can adjust the shooting angle of the industrial camera according to requirements. The device can be mounted on a chained-type eggbeater and can identify and remove yolk-dispersed eggs automatically. The device can achieve identification and separation of yolk-dispersed eggs in place of manual operation.

Description

technical field [0001] The invention belongs to the technical field of food processing equipment, and in particular relates to a method and device for online recognition and separation of loose yolk eggs based on machine vision. It is installed on the chain egg breaker to automatically identify and remove loose yolk eggs, which can replace manual detection and separation of loose yolk eggs. Background technique [0002] Chain egg beater is a machine that can automatically open eggs and separate egg whites from egg yolks. Separating egg whites from egg yolks is the main function of the machine. Egg yolk membrane rupture will leak into the egg white, affecting the quality of the egg white. For this reason, when domestic egg powder processing enterprises use imported chain-type egg beaters, they must arrange workers to stand in the egg white and yolk separation section of the egg beater. Combine the egg yolk cup and egg white bucket to separate them, and pour the loose yolk e...
