Device for mounting component
First Claim
1. A component mounting apparatus comprising:
- a nozzle for holding a component at its lower end, said component being supplied from a component supply unit;
a nozzle elevating means for moving said nozzle up/down;
a nozzle moving means for moving said nozzle horizontally;
obstacles higher than a height with which said component is picked up from said component supply unit or a height with which said component is to be mounted on a board conveyed by conveyance rails; and
acontrol means for controlling said nozzle elevating means and said nozzle moving means so that said component moved by said nozzle moving means is mounted on said board;
wherein said control means stores positions and heights of a plurality of said obstacles disposed between said component supply unit and said board; and
when said nozzle having picked up said component in a position to pick up said component from said component supply unit is to move to a position to mount said component on said board, said control means locates said nozzle at a height high enough not to interfere with a first one of said obstacles and then moves said nozzle to a height high enough not to interfere with a next one of said obstacles in sync with the time when said nozzle has finished passing over said first obstacle.

Abstract
An object of the present invention is to provide a component mounting apparatus and a component mounting method in which a movement time of a nozzle can be shortened so that production efficiency can be improved.
There is provided a control means for controlling movement positions and movement timings of a nozzle elevating means and a nozzle moving means. The control means stores positions and heights of obstacles located between a component supply unit and a circuit board in advance. The control means moves down a nozzle in sync with the time when the nozzle has finished passing over each obstacle after an electronic component has been photographed by a component camera. Alternatively, the control means moves the nozzle in a path to avoid the obstacles. In addition, in a component mounting region, the nozzle moves at a component mounting region movement height and the component is mounted by the nozzle moved down from the component mounting region movement height. Accordingly, it is possible to shorten an elevating stroke of the nozzle (5). In addition, the nozzle can be elevated in an arc trajectory.

3. A component mounting apparatus comprising:
-
a nozzle for holding a component at its lower end, said component being supplied from a component supply unit; a nozzle elevating means for moving said nozzle up/down; a nozzle moving means for moving said nozzle horizontally; obstacles higher than a height with which said component is picked up from said component supply unit or a height with which said component is to be mounted on a board conveyed by conveyance rails; and a control means for controlling said nozzle elevating means and said nozzle moving means so that said component moved by said nozzle moving means is mounted on said board; wherein said control means stores positions and heights of a plurality of said obstacles disposed between said component supply unit and said board; and
when said nozzle having picked up said component in a position to pick up said component from said component supply unit is to move to a position to mount said component on said board, said control means determines a horizontal path to allow said nozzle to move to a component mounting position on said board while keeping a predetermined height, and moves said nozzle in said horizontal path.

4. A component mounting apparatus including:
-
a nozzle for holding a component at its lower end so as to mount said component on a board, said component being supplied from a component supply unit; a nozzle elevating means for moving said nozzle up/down;
a nozzle moving means for moving said nozzle horizontally; anda control means for controlling said nozzle elevating means and said nozzle moving means so that said component moved by said nozzle moving means is mounted on said board, wherein;
said control means controls said nozzle elevating means so that said nozzle approaches a component mounting region movement height close to said board when said nozzle has arrived in a component mounting region above said board; and
the control means controls said nozzle moving means so that said nozzle holding said component at said component mounting region movement height is moved to a component mounting position on said board so as to mount said component from said component mounting region movement height to said component mounting position; and
board marks provided on end portion sides of said board are recognized, and said component mounting region is calculated based on said recognized board marks. - View Dependent Claims (5, 6, 7)
