Abstract
In a component mounting apparatus, a component (8) is held, positioned and mounted at a predetermined position of a member (4) to be mounted. After the component (8) is mounted to the member (4), a component holding member (5) is raised by a distance corresponding approximately to a push-in amount by which the component holding member (5) has been moved down to mount the component, then stopped to retain the component (8), is kept in this state while retaining the component for a fixed time, and is raised again to a predetermined position.
Claims42
A component mounting apparatus which comprises:
- a component holding member for holding a component and moving up and down relative to a mounting member on which the component is to be mounted;
- a driving apparatus for moving the component holding member up and down;
- and
- a control apparatus controlling the driving apparatus so that the component holding member holding the component moves down towards the mounting member, brings the held component into contact with the mounting member, moves further downward by a push-in amount, mounts the component to the mounting member, moves up by a distance corresponding approximately to the push-in amount, stops temporarily thereby retaining the component, maintains a retaining state for a fixed time, and then moves up again.
A component mounting apparatus which comprises:
- a component holding member for holding a component and moving up and down relative to a mounting member on which the component is to be mounted;
- a driving apparatus for moving the component holding member up and down;
- and
- a control apparatus controlling the driving apparatus so that the component holding member holding the component moves down towards the mounting member, brings the held component into contact with the mounting member, moves further downward by a push-in amount, mounts the component to the mounting member, moves up at a low speed enabling prevention of a leap of the component for only a period enabling the prevention of the leap of the component, and then moves up at a speed higher than said low speed after said period.
A component mounting method which comprises:
- moving down a component holding member holding a component towards a mounting member on which the component is to be mounted;
- bringing the held component in contact with the mounting member, and then lowering the component further by a push-in amount thereby mounting the component to the mounting member;
- thereafter raising the component holding member by a distance corresponding approximately to the push-in amount of the component holding member, and then stopping the component holding member temporarily thereby retaining the component;
- and
- raising the component holding member again after a lapse of a fixed time in a state wherein the component is retained by the component holding member.
