Patent ID: 8413322

Claim:
A component mounting method, comprising: suctioning a component to a suction bit section of a movable part, and mounting the component onto a mounting object, wherein, in mounting the component suctioned to the suction bit section of the movable part onto the mounting object, the component is mounted on the mounting object, while controlling a determination value of a force determination unit for determining a force applied to the movable part in a vertical direction to a target value by moving the movable part in the vertical direction, in a state where a force for compensating for a gravitational force of a weight of the movable part or a total weight of the movable part and the component suctioned to the suction bit section of the movable part, on a basis of the weight of the movable part or the total weight of the movable part and the component suctioned to the suction bit section of the movable part, is caused to act on the movable part by a balance mechanism engaging with a movable shaft of the movable part on one side of a fulcrum and engaging with a balance weight on another side of the fulcrum, the fulcrum being placed between the movable part and the balance weight, and the balance weight having a weight determined on a basis of the weight of the movable part or the total weight of the movable part and the component suctioned to the suction bit section of the movable part.
