when the position detection module 121 on the PIN ejecting mechanism 12 detects that a liquid crystal panel is located thereon, the control module controls the driving member 21 to start, the first rotating shaft 211 and the second rotating shaft 212 rotate synchronously, and simultaneously drive the first transmission shaft 23 and the second transmission shaft 24 to rotate, so that the worms at the two ends of the first transmission shaft 23 and the second transmission shaft 24 drive the turbines to rotate, and drive the four lifting rods 22 to descend synchronously, and after the supporting frame 11 descends to the lowest preset position, the liquid crystal panel is transferred to a repair processing position. After the liquid crystal panel is taken down, the control module controls the driving part 21 to rotate reversely, so that the four lifting rods 22 synchronously lift the supporting frame 11 until the highest preset position is reached, and the blanking machine of the liquid crystal panel places the liquid crystal panel on the plurality of top PIN mechanisms 12 again. The process is repeated, and the automatic feeding and discharging and product repairing functions of the liquid crystal panel are achieved.
