Abstract:
1. A liquid suction device comprising: an arm movable in three-dimensional directions; plural rails disposed parallel to each other so as to extend upward from the arm; a pump; a pipe having a body, a tip end for functioning as a nozzle, and having a rear end connected to the pump; a pipe fixing member to which pipe is fixed, having plural through holes for inserting the plural rails therethrough, and movable relative to the arm along the plural rails; and plural resilient members fixed to the arm so as to be disposed between the arm and the pipe fixing member; wherein: the resilient members are conductive, the pipe fixing member has a conducting layer on a surface thereof to permit electrical conduction between ones of the resilient members, when ones of the resilient members are in contact with the pipe fixing member, and the liquid suction device further comprises a controller electrically connected to the resilient members to detect electrical conduction states between the ones of the resilient members, the controller configured to determine a position and an inclination of the pipe fixing member relative to the plural rails, based on the electrical conduction states detected between the ones of the resilient members.
