Liquid drop generation and collection integrated device

The utility model provides a liquid drop generating and collecting integrated device which comprises a material placing table, a moving frame arranged above the material placing table, an air pressure mechanism installed on the moving frame and a liquid transferring mechanism installed on the moving frame. A chip set used for generating liquid drops, a pore plate used for collecting the liquid drops, a placing plate used for placing gun heads and a recycling bin are placed on the material placing table, the chip set generates the liquid drops under a pressing cover of the air pressure mechanism, the pipetting mechanism takes the gun heads from the placing plate and transfers the liquid drops on the chip set to the pore plate through the gun heads, and the recycling bin is used for recycling the liquid drops on the chip set. After the liquid drops are transferred, the pipetting mechanism enables the gun head to fall into the recycling barrel, automatic treatment of liquid drop generation, pressurization, colle
