According to the technical scheme, the residual material removing mechanism is characterized in that the residual material removing mechanism comprises an objective table and a residual material removing
assembly, the objective table is used for fixing the
liquid crystal panel, and the objective table can be of a turnover platform or a
robot arm or other structures; the residual material removing
assembly removes residual materials on one side of a circuit layer of the
liquid crystal panel through a clamping jaw
assembly A. The clamping jaw assembly A moves in the Z-axis direction under dragging of the first module and moves in the Y-axis direction under dragging of the Y-axis controller. The upper clamping jaw and the lower clamping jaw drag the upper friction part and the lower friction part to clamp the residual material area of the
liquid crystal display panel when relatively translating under the control of the
servo control system, and can be suitable for the
liquid crystal display panels with different thickness specifications; and under dragging of the Y-axis controller, different friction forces are generated on the upper surface and the lower surface of the liquid
crystal panel residual material area, meanwhile,
airflow with certain pressure is applied to the separation area through the air
pipe, and therefore the
cut liquid
crystal panel residual materials are separated.
