Abstract

A sealant forming nozzle is a sealant forming nozzle that forms sealant by being moved along a target surface, and includes: a main body portion covering the target surface and forming a cavity, the cavity including an opening that opens only toward a rear side in a movement direction and a closing surface provided on a front side in the movement direction; and a discharge hole that is formed in the main body portion and guides a sealing material supplied from outside into the cavity. The closing surface extends so as to approach the target surface toward the front side in the movement direction in a cross-sectional view in a direction orthogonal to the movement direction and along the target surface.

First claim

The invention claimed is:

1. A sealant forming nozzle for forming sealant by being moved along a target surface, the sealant forming nozzle comprising:
a main body portion covering the target surface and forming a cavity, the cavity including an opening which opens only toward a rear side in a movement direction and a closing surface provided on a front side in the movement direction; and
a discharge hole formed in the main body portion and configured to guide a sealing material supplied from outside into the cavity,
the closing surface extending so as to approach the target surface toward the front side in the movement direction in a cross-sectional view in a direction orthogonal to the movement direction and along the target surface.

2. The sealant forming nozzle according to claim 1 , wherein a portion of the closing surface on the target surface side is curved in a direction away from the target surface toward the front side in the movement direction.

3. The sealant forming nozzle according to claim 1 , wherein a forming surface, which is an end edge of the opening on a side opposite to the target surface, extends away from the target surface toward the rear side in the movement direction in a cross-sectional view in a direction orthogonal to the movement direction and along the target surface.

4. The sealant forming nozzle according to claim 3 , wherein the forming surface has a curved surface shape that is convex in a direction toward the target surface.

5. The sealant forming nozzle according to claim 1 , wherein an end edge of the discharge hole on the rear side in the movement direction extends linearly in a direction orthogonal to the movement direction and along the target surface.

6. The sealant forming nozzle according to claim 5 , wherein the discharge hole has a rectangular shape when viewed from a direction orthogonal to the target surface.

7. A sealant forming apparatus comprising:
the sealant forming nozzle described in claim 1 ;
a supply portion configured to supply the sealing material to the discharge hole; and
a moving portion configured to move the sealant forming nozzle in the movement direction.

8. A sealant forming method using the sealant forming nozzle described in claim 1 , the method comprising:
installing the sealant forming nozzle at the target surface;
supplying the sealing material from the discharge hole into the cavity;
moving the sealant forming nozzle in the movement direction while supplying the sealing material; and
after the sealing material is cured, separating the sealant forming nozzle from the sealant by further moving the sealant forming nozzle toward the front side in the movement direction.
