Title:
METAL LIBERATION DEVICE OF PRINTED CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2014/196773
Kind Code:
A1
Abstract:
A metal liberation device of a printed circuit board according to the present invention comprises: a body casing of which upper and lower ends are opened so as to introduce or discharge a PCB particle to be separated, the body casing being formed to have a hollow conical shape with an increasing diameter from a lower portion to an upper portion; a rotation body arranged within the body casing, of which upper and lower ends are opened and which is formed to have a hollow conical shape with an increasing diameter from a lower portion to an upper portion, the rotation body being rotatably connected to a rotary shaft disposed in a shaft center along the longitudinal direction of the body casing; a lower casing into which the PCB particle is injected, the lower casing being connected to communicate with the lower end of the body casing; and at least one metal layer separation unit formed in the longitudinal direction along the inner circumferential surface of the body casing. The metal liberation device of a printed circuit board according to the present invention can maximize the liberation of the metal surface layer of PCB by shear stress from the PCB particle circling upwardly by injecting compressed air, in which a vortex is formed, into the body casing, thereby increasing the metal recovery yield of the entire PCB.
