Abstract
For sorting silkworm chrysalises, a feed mechanism positions silkworm chrysalises on a delivery mechanism. The delivery mechanism receives and carries the silkworm chrysalises from the feed mechanism. A detection mechanism detects a female silkworm chrysalis based on an optical wavelength emitted by the female silkworm chrysalis. A sorting mechanism that sorts the silkworm chrysalises, putting female silkworm chrysalises into a female collecting box, and male silkworm chrysalises into male collecting box.
Claims16
An apparatus comprising:
- a feed mechanism that positions silkworm chrysalises on a delivery mechanism;
- the delivery mechanism comprising a plurality of positions that receives and carries the silkworm chrysalises from the feed mechanism;
- a detection mechanism comprising a charge-coupled device (CCD) camera, a light emitting diode (LED), a green fluorescence filter, and a dichroic mirror that detects a female silkworm chrysalis based on an optical wavelength emitted by the female silkworm chrysalis, wherein light from the LED goes through the green fluorescence filter producing a green light with a 554 nanometer (nm) central wave length and 30 nm bandwidth that is refracted by the dichroic mirror on the silkworm chrysalis, and wherein light from the silkworm chrysalis is transmitted through the dichroic mirror passing through an orange fluorescence filter with a 586 nm central wave length and a 20 nm bandwidth to the CCD camera;
- and
- a sorting mechanism that sorts the silkworm chrysalises, putting female silkworm chrysalises into a female collecting box, and male silkworm chrysalises into male collecting box.
