Capillary absorption sucking cup

The utility model discloses a capillary absorption sucking cup. The sucking cup comprises a sucking cup support, sucking cup bodies, a capillary absorption system and a position detection device. The sucking cup support comprises a sucking cup rack base, a sucking cup supporting frame, a sucking cup gripping handle, a sucking cup rack upper cover and a sucking cup rack connecting mechanism. The sucking cup bodies are provided with capillary tube bundles. The capillary absorption system comprises a heater, a liquid guide pipe, a humidifying pump, a micro motor, a liquid storage device, a switch, a controller and a power source. The position detection device comprises a horizontal dial, a horizontal plane angle pointer, a vertical plane angle pointer and a vertical dial. According to the capillary absorption sucking cup, the principle of negative pressure absorption and capillary absorption is adopted, the problem that absorbed objects are damaged due to the facts that an existing sucking cup is large in absorption force, concentrated in absorption force and large in initial working pressure can be solved, and the capillary absorption sucking cup has the advantages of being small in initial working pressure, wide in applied range, suitable for the absorbed objects of different sizes and specifications, high in reliability and the like.
