Abstract

A sealant forming nozzle is disposed to seal an object that a sectional shape in a first plane is a stair shape. The sealant forming nozzle includes a shaping section and a guide section. The shaping section includes a shaping surface orthogonal to the first plane, and a sealant output hole to supply a sealant to a space surrounded by the object and the shaping surface. The guide section has a guide surface. The guide surface is orthogonal to the first plane and formed to have a line contact with a corner section of an upper step of the stair shape.

First claim

The invention claimed is:

1. A sealant forming nozzle for sealing an object that a sectional shape in a first plane is a stair shape, comprising:
a shaping section configured to shape a sealant; and
a guide section disposed in a position where neighbors the shaping section in a first direction orthogonal to the first plane,
wherein the shaping section comprises:
a first contact section which contacts an upper surface of an upper step of the stair shape;
a second contact section which contacts an upper surface of a lower step of the stair shape;
a shaping surface orthogonal to the first plane and formed to connect the first contact section and the second contact section;
a sealant output hole disposed to supply the sealant to a space surrounded by the forming surface and the object, and
wherein the guide section comprises:
a guide surface orthogonal to the first plane and formed to have a line contact with a corner section of the upper step.

2. The sealant forming nozzle according to claim 1 , wherein the guide surface has a convex shape.

3. The sealant forming nozzle according to claim 2 , wherein an intersection line of the guide surface and the first plane is of an arc.

4. The sealant forming nozzle according to claim 1 , wherein the first contact section is formed to have a line contact with the upper surface of the upper step.

5. The sealant forming nozzle according to claim 4 , wherein an intersection line of the surface of the first contact section and the first plane is of an arc, in a neighborhood of a contact line between the first contact section and the upper surface of the upper step.

6. The sealant forming nozzle according to claim 1 , wherein the second contact section is formed to have a line contact with an upper surface of the lower step.

7. The sealant forming nozzle according to claim 6 , wherein an intersection line of a surface of the second contact section and the first plane is of an arc, in neighborhood of a contact line between the second contact section and the upper surface of the lower step.

8. The sealant forming nozzle according to claim 1 , wherein a direction along the intersection line of the shaping surface and the first plane is a second direction, and
wherein a width of the sealant output hole along the second direction is larger than that of the sealant output hole along the first direction.

9. The sealant forming nozzle according to claim 1 , wherein the guide section is disposed on one side of the sealant output hole.

10. A sealant forming apparatus comprising:
a sealant forming nozzle for sealing an object that a sectional shape in a first plane is a stair shape, wherein the sealant forming nozzle comprises:
a shaping section configured to shape a sealant; and
a guide section disposed in a position where neighbors the shaping section in a first direction orthogonal to the first plane,
wherein the shaping section comprises:
a first contact section which contacts an upper surface of an upper step of the stair shape;
a second contact section which contacts an upper surface of a lower step of the stair shape;
a shaping surface orthogonal to the first plane and formed to connect the first contact section and the second contact section;
a sealant output hole disposed to supply the sealant to a space surrounded by the forming surface and the object, and
wherein the guide section comprises:
a guide surface orthogonal to the first plane and formed to have a line contact with a corner section of the upper step, and

a sealant supply section configured to supply the sealant to the sealant output hole.

11. A sealant forming method for sealing an object that a sectional shape in a first plane is a stair shape, comprising:
(A) bringing a sealant forming nozzle into contact with the object;
wherein the sealant forming nozzle comprises:
a shaping section configured to shape a sealant; and
a guide section disposed in a position which neighbors the shaping section in a first direction orthogonal to the first plane,
wherein the shaping section comprises:
a first contact section which contacts an upper surface of an upper step of the stair shape;
a second contact section which contacts an upper surface of a lower step of the stair shape;
a shaping surface orthogonal to the first plane and formed to connect the first contact section and the second contact section; and
a sealant output hole disposed to supply the sealant to a space surrounded by the shaping surface and the object,
wherein the guide section comprises:
a guide surface orthogonal to the first plane and formed to have a line contact with a corner section of the upper step,
(B) supplying the sealant through the sealant output hole to the space; and
(C) moving the sealant forming nozzle to the first direction while the guide section precedes the shaping section.
