System, method and apparatus for fiber sample preparation for image analysis
View Patent ↗The present invention is an apparatus, system and method for preparing samples for analysis including a mechanical fiber cutting apparatus. The mechanical fiber cutting apparatus has two or more cutter blades under the control of a blade moving mechanism. A fiber chamber is positioned to receive the one or more cut fibers created by the cutting action of the two or more cutter blades. The pressurized gas source connected to the fiber chamber transfers the one or more cut fibers into a sample preparation housing. The one or more cut fibers are distributed randomly onto a sample slide within the sample preparation housing.
1. A precision mechanical fiber cutting apparatus comprising:
a vertical blade moving mechanism that moves in a vertical plane;
at least 3 substantially vertical parallel fixed cutting blades connected to the vertical blade moving mechanism to move in a vertical plane to punch out one or more cut fibers;
a cutting stage positioned below the vertical blade moving mechanism to support a fiber sample against a downward cutting motion of the at least 3 substantially vertical parallel fixed cutting blades, wherein the cutting stage comprises
a top and a bottom connected to 1 or more side walls having an inlet aperture and an outlet aperture, wherein the top comprises at least 3 slits to receive the at least 3 substantially vertical parallel fixed cutting blades to allow transport of the fiber sample into the cutting stage, wherein the top supports the fiber sample to allow the at least 3 substantially vertical parallel fixed cutting blades to punch out the fiber sample into one or more cut fibers having substantially uniformed lengths with substantially uniformed ends;
a fiber chamber connected to the outlet aperture by a conduit to receive the one or more cut fibers; and
a pressurized gas source connected to the inlet aperture to transfer the one or more cut fibers to the fiber chamber, wherein the one or more cut fibers are deposited in a random distribution onto a sample slide within the fiber chamber.
2. The apparatus of claim 1 , wherein the blade moving mechanism is a pneumatic ram, a hydraulic ram, an electric motor and combinations thereof.
3. The apparatus of claim 1 , wherein the at least 3 substantially vertical parallel fixed cutting blades comprise 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 or more fixed blades.
4. The apparatus of claim 1 , wherein the at least 3 substantially vertical parallel fixed cutting blades individually comprise a conventional razor blade, a blade, a serrated blade, a metal wire, a plastic fiber, a composite fiber, a plastic blade, or a composite material.
5. The apparatus of claim 1 , wherein the conduit comprises an inlet pressure fitting to allow an increase in pressure and an outlet aperture to allow a reduction in the pressure.
6. The apparatus of claim 1 , wherein the pressurized gas source is a compressor, a tank, a gas line, or a combination thereof.
