Capillary force is attracting two objects while a liquid bridge is generated between them. By using the capillary force, it is possible to pick and place small objects having various shapes. In previous study, we have developed a mechanism for discharging a droplet. The mechanism is composed of a piston for pushing a liquid and a valve for preventing a back flow. However, it is difficult to discharge the droplet with a diameter of less than 1mm because the seal of the piston is not sufficient. In this study, we have improved the mechanism by replacing the piston pump to a diaphragm pump. In experiments, we have succeeded to discharge a droplet with a diameter of 0.5mm, half diameter of the previous mechanism. In pick-and-place experiments, we have evaluated the positioning errors of 1mm3 acrylic cubes and 0603 chip capacitors.
