Chip classification device and chip classification method

The invention discloses a chip classification device and a chip classification method. The chip classification device comprises a chip bearing part, a wafer, a first chip receiving part, a pressure applier and a separator, wherein the chip bearing part is provided with a first surface and a second surface opposite to the first surface; the wafer comprises a first chip attached to the first position of the first surface; the first chip receiving part is provided with a third surface and a fourth surface opposite to the third surface, wherein the third surface is positioned on the opposite sideof the first surface; the pressure applier applies pressure to the first position corresponding to the second surface so that the first chip is mutually attached to the third surface; and the separator weakens the attachment force between the first chip and the first surface.
