Method for mounting a component

1. A method of mounting a component using an apparatus comprising a plurality of spindles respectively comprising nozzles, each of which is configured to rotate about a first pivot provided at a center of the each spindle, a head body which is configured to rotate about a second pivot provided at a center of the head body and substantially parallel to the first pivot, and the head body configured to rotatably support the spindles, and a controller configured to control the spindles and the head body to perform the method, the method comprising:

performing a pickup operation comprising:

rotating the spindle about the first pivot from an initial orientation to a pickup orientation with respect to the head body;

picking up the component; and

rotating the spindle from the pickup orientation to the initial orientation so that the component is oriented to a mounting orientation at which the component is to be mounted on a substrate,

wherein the rotating the spindle about the first pivot from the initial orientation to the pickup orientation occurs before the picking up the component; and

performing a mounting operation comprising transferring the picked-up component to a mounting position of the substrate during which each of the spindles is retained at the initial orientation with respect to the head body.

2. The method of claim 1 , further comprising controlling a first power device configured to rotate the spindles about the first pivot, and a second power device configured to rotate the head body about the second pivot,

wherein the controlling operation comprises controlling both the first power device and the second power device during the mounting operation.

3. The method of claim 2 , wherein, by controlling both the first power device and the second power device to perform the mounting operation, both the head body and the spindles rotate about the second pivot and the spindles rotate about the first pivot, during the mounting operation.

4. The method of claim 1 , wherein the performing pickup operation comprises:

controlling both the head body and the spindles to rotate about the second pivot and controlling the spindles not to rotate about the first pivot, during the mounting operation.

5. The method of claim 1 , wherein the pickup operation comprises:

rotating the spindle about the first pivot by a predetermined angle from the initial orientation so that the spindle is set to the pickup orientation;

controlling each of the nozzles to pick up the component while the spindle is set to the pickup orientation; and

rotating the spindle to be set to the initial orientation.

6. The method of claim 5 , wherein the mounting operation comprises synchronously-rotating the spindles and the head body about the second pivot while the spindles maintain their initial orientations with respect to the head body.

7. The method of claim 1 , wherein the mounting operation comprises synchronously-rotating the spindles and the head body about the second pivot while the spindles maintain their initial orientations with respect to the head body.

8. The method of claim 1 , wherein the rotating the spindle from the pickup orientation to the initial orientation comprises rotating the spindle from the pickup orientation to the initial orientation about the first pivot.

9. The method of claim 1 , wherein the rotating the spindle from the pickup orientation to the initial orientation occurs after the picking up the component and before the performing the mounting operation.

10. The method of claim 1 , wherein the performing the pickup operation is performed before the performing the mounting operation.

11. A method of mounting a component using an apparatus comprising a plurality of spindles respectively comprising nozzles and configured to rotate about a first pivot provided at a center of the each spindle, a head body configured to rotate about a second pivot provided at a center of the head body, and the head body configured to support the spindles rotatably, a power transmitting shaft connected to the spindles through a gear, and a controller configured to control the spindles and the head body to perform the method, the method comprising:

controlling the head body to rotate about the second pivot and the spindles to rotate about the first pivot;

if the power transmitting shaft rotates the gear about the second pivot in a first rotational direction when the head body does not rotate about the second pivot in any rotational direction, controlling the spindles to rotate about the first pivot in a second rotational direction opposite to the first rotational direction due to connection between the spindles and the gear,

if the head body rotates about the second pivot in the first rotational direction when the gear does not rotate about the second pivot in any rotational direction, controlling the spindles to rotate about the first pivot in the first rotational direction due to the connection between the spindles and the gear, and controlling the spindles to rotate along with the head body about the second pivot in the first rotational direction due to connection between the spindles and the gear, and

if both the head body and the gear rotate about the second pivot in the first rotational direction, controlling the spindles not to rotate about the first pivot and to rotate about the second pivot in the first rotational direction due to the connections between the head body, the spindles and the gear so that the spindles retain their orientations with respect to the head body.
