Automatic centering cell tray pressure-stabilizing mechanism

The utility model relates to an automatic centering cell tray pressure-stabilizing mechanism. The provided mechanism is capable of preventing a cell tray from moving when a nutrition pot is taken out by a mechanical arm, so as to ensure smooth conduction of subsequent pot movement. According to the technical scheme, the automatic centering cell tray pressure-stabilizing mechanism is characterized by comprising a bracket, a pair of top plates, a pair of pressure plates and an air cylinder, wherein the bracket is used for horizontally supporting the cell tray; the pair of top plates is used for pushing transverse two ends of the cell tray to realize centering of the cell tray; the pair of pressure plates is used for withholding vertical two ends of the cell tray on the bracket to prevent the cell tray from moving; and the air cylinder is fixedly arranged below the bracket and is used for respectively driving the top plates and the pressure plates to move through connecting rods.
