Laser instrument and method for sorting male and female graines

Abstract

The invention discloses a male and female graine laser separator and a separation method thereof. The separator comprises an elevated working platform, an egg raising paper positioning system, a graine color image processing system, a laser generation and light deflection scanning and egg launching system, and a computer. The separation method comprises the following steps: starting the separator, resetting the shifted working platform, placing egg raising paper on a negative-pressure adsorption platform, and starting an air pump to absorb the egg raising paper to be flat; starting a color image acquisition program, and controlling a color image sensor to shoot an egg raising paper image and transmit the egg raising paper image to the computer which processes data, gives out a work instruction for launching time-sequence laser pulse to a laser generator and an electric control device, and gives out a work instruction for light deflection scanning to a galvanometric scanning and electric control device, and generating laser beams to shoot female graine; and placing novel egg raising paper after the task is completed, and repeating the steps. The separator can automatically and accurately separate male and female graines with different graine colors at a high speed so as to save labor and improves the separation precision.

Description

technical field [0001] The invention relates to the technical field of sorting female and male silkworm eggs, in particular to an efficient and labor-saving automatic laser sorter and sorting method for male and female silkworm eggs. Background technique [0002] With the rapid development of biological genetic engineering, a new high-tech discipline of insect developmental sex control has been born, for example, the silkworm balance lethal gene that allows black female silkworm eggs to die on their own while keeping white male silkworm eggs alive The successful research of gender control technology has made China the first country in the world to realize large-scale special breeding of high-quality and high-yield male silkworms in rural areas; and in the process of producing the male silkworm eggs, high-quality, conventional Only by crossing female silkworms with male silkworms in the balanced lethal line can all the female silkworm eggs in the offspring die, and only the w...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the time-consuming and labor-intensive sorting of male and female silkworm eggs of different egg colors in the existing silkworm balanced lethal system, which is inefficient and difficult to meet the time progress requirements of silkworm seed production, and is prone to human errors. to provide a laser sorter and a sorting method that can automatically, high-speed and accurately sort male and female silkworm eggs of different egg colors, thereby saving labor and improving the sorting accuracy
