Abstract

An application device includes: a discharger having a discharge port configured to discharge an application material; a first supporter movably supporting the discharger around a position of the discharge port; and a first driver configured to move the discharger supported by the first supporter. An application method, includes: making a central axis of a discharge port coaxial with any rotation axis in an arm portion of an application robot, the discharge port being configured to discharge an application material; and applying the application material to an applied surface while moving a discharger having the discharge port around a position of the discharge port.

First claim

What is claimed is:

1. An application device, comprising:
a discharger having a discharge port configured to discharge an application material;
a first supporter movably supporting the discharger around a position of the discharge port;
a first driver configured to move the discharger supported by the first supporter, the first driver having an output shaft;
a drive-side member coupled to the output shaft of the first driver; and
a driven-side member disposed on the discharger, wherein
the drive-side member has an opening extending in a direction perpendicular to the output shaft of the first driver, and
the driven-side member has a pin inserted through the opening to transmit rotation of the drive-side member to the driven-side member.

2. The application device according to claim 1 , wherein
the first supporter has an arc-shaped first rail,
the discharger has a base side supported by the arc-shaped first rail; and
the discharger is configured to slide along the arc-shaped first rail by the first driver.

3. The application device according to claim 2 , wherein
the first supporter includes a protrusion configured to restrict movement of the discharger.

4. The application device according to claim 1 , wherein
the output shaft of the first driver is coupled to a base side of the discharger.

5. The application device according to claim 4 , wherein
the driven-side member is disposed on the base side of the discharger, and
the drive-side member and the driven-side member are configured to transmit a power of the first driver between the drive-side member and the driven-side member.

6. The application device according to claim 5 , wherein
the pin has a roller inserted through the opening, and
the roller is configured to linearly move along the opening in association with movement of the discharger while rotating.

7. The application device according to claim 1 , wherein
the first driver is arranged such that the output shaft of the first driver is perpendicular to a central axis of the discharge port.

8. The application device according to claim 2 , further comprising
a mounting portion secured to the first driver and the first supporter.

9. The application device according to claim 8 , further comprising
a second supporter having an arc-shaped second rail, the arc-shaped second rail movably supporting the mounting portion, wherein
the mounting portion is configured to slide along the arc-shaped second rail.

10. The application device according to claim 9 , wherein
the arc-shaped second rail is configured to movably support the mounting portion around the position of the discharge port.

11. The application device according to claim 9 , further comprising
a second driver configured to move the mounting portion supported by the second supporter, along the arc-shaped second rail.

12. An application robot, comprising:
an arm portion; and
the application device according to claim 1 , the application device being mounted on the arm portion such that any rotation axis of the arm portion is coaxial with a central axis of the discharge port.

13. An application device, comprising:
a discharger having a discharge port configured to discharge an application material;
a first supporter movably supporting the discharger around a position of the discharge port;
a first driver configured to move the discharger supported by the first supporter;
a mounting portion secured to the first driver and the first supporter; and
a second supporter having an arc-shaped second rail, the arc-shaped second rail movably supporting the mounting portion, wherein
the first supporter has an arc-shaped first rail,
the discharger is supported by the arc-shaped first rail,
the discharger is configured to slide along the arc-shaped first rail by the first driver,
the mounting portion is configured to slide along the arc-shaped second rail, and
the arc-shaped second rail is arranged intersecting with the arc-shaped first rail.

14. The application device according to claim 13 , wherein
the arc-shaped second rail extends in a direction perpendicular to the arc-shaped first rail.

15. The application device according to claim 13 , wherein
the discharger has a base side supported by the arc-shaped first rail.

16. The application device according to claim 15 , wherein
the arc-shaped second rail extends in a direction perpendicular to the arc-shaped first rail.
