System for forming a micro-assembler
View Patent ↗A xerographic micro-assembler system, method and apparatus that includes a sorting unit that is adapted to receive a plurality of micro-objects. The micro-objects can also be sorted and oriented on the sorting unit and then transferred to a substrate. The system, method and apparatus can also include a device for detecting errors in at least one of the micro-objects on the sorting unit and a protection means for preventing an improper micro-object from being transferred to the substrate. The system, method and apparatus can also include an organized micro-object feeder assembly that can transfer at least one of a plurality of micro-objects to the sorting unit or directly to the substrate.
1. A system for forming a micro-assembly comprising:
means for sorting and orienting a plurality of micro-objects on a sorting unit adapted to receive the micro-objects;
means for detecting an error in at least one of the plurality of micro-objects on the sorting unit, wherein the means for detecting an error includes a camera and image recognition software;
means for transferring the micro-objects from the sorting unit to a substrate; and
means for attaching the micro-objects to the substrate.
2. The system of claim 1 , further comprising:
means for sending information regarding the error in at least one of the plurality of micro-objects to the sorter; and
protection means for preventing a micro-object having an error from being transferred to the substrate.
3. The system of claim 2 , wherein the protection means sends a wave pattern to remove the micro-object having an error.
4. The system of claim 1 , wherein the error is an alignment error, the system further comprising:
a realignment means for realigning a micro-object having the alignment error.
5. The system of claim 1 , further comprising:
means for sending information regarding the error in at least one of the plurality of micro-objects to the sorter; and
protection means for removing a micro-object having an error, or for removing all the micro-objects in a region surrounding the micro-object having an error.
6. The system of claim 1 , further comprising:
means for charging the sorting unit with an optical pattern writer, a static charge or a magnetic field, wherein at least one micro-object is a charge encoded micro-object or a magnetic field pattern encoded micro-object that is attracted to the sorting unit.
7. The system of claim 1 , further comprising:
means for transferring the plurality of micro-objects to a second sorting unit, wherein the second sorting unit transfers the micro-objects to the substrate.
8. The system of claim 7 , further comprising:
means for charging the second sorting unit with an optical pattern writer, a static charge or a magnetic field, wherein at least one micro-object is a charge encoded micro-object or a magnetic field pattern encoded micro-object that is attracted to the sorting unit.
