The invention discloses a vibration splinter method and device. The vibration splinter method includes the following steps: a face plate is provided, the face plate includes a first substrate and a second substrate, the first substrate has a first crack, the second substrate is disposed opposite to the first substrate, and the second substrate has a second crack; a vibration component is disposedon the face plate, the vibration component corresponds to the first crack of the first substrate and the second crack of the second substrate; and the vibration component is utilized to vibrate the first crack and the second crack to split the face plate into a first block face plate and a second block face plate. The vibration splinter method and device can make stress interference caused by splitting of the face plate reduce, so that it is no longer necessary to spend time repairing the face plate after the splitting, and therefore, the man-hour can be saved and the productivity can be improved, and the vibration splinter method and device can also make the splitting yield of the face plate greatly increase, thereby reducing the amount of waste, and the production cost is reduced.
