Abstract

There is provided an adhesive application apparatus capable of efficiently applying an adhesive without inhibiting curing of the adhesive. An adhesive application apparatus of the present invention includes a mounting table 10, an adhesive dosing unit 20, and an ultraviolet irradiation unit 30, and it applies a delayed-ultraviolet-curable adhesive 200 to a surface of a panel 100. The panel 100 is mounted on a mounting surface S10 of the mounting table 10. The adhesive dosing unit 20 applies the adhesive 200 to the surface of the panel 100 mounted on the mounting table 10 by discharging the adhesive 200 from an adhesive dosing port H20. The ultraviolet irradiation unit 30 irradiates the adhesive 200 dosed from the adhesive dosing port H20 with ultraviolet light L. Here, the ultraviolet irradiation unit 30 irradiates the adhesive 200 with the ultraviolet light L along the mounting surface S10 before the adhesive 200 dosed from the adhesive dosing port H20 is applied to the surface of the panel 100.

First claim

What is claimed is:

1. An adhesive application apparatus for applying a delayed-ultraviolet-curable adhesive to a surface of an adherend, the adhesive application apparatus comprising:
a mounting table having a mounting surface for mounting the adherend thereon;
an adhesive dosing unit for applying the adhesive to the surface of the adherend mounted on the mounting table by discharging the adhesive from an adhesive dosing port; and
an ultraviolet irradiation unit for irradiating the adhesive dosed from the adhesive dosing port with ultraviolet light, wherein
the ultraviolet irradiation unit is oriented to irradiate the adhesive with the ultraviolet light in a direction substantially parallel to the mounting surface before the adhesive dosed from the adhesive dosing port is applied to the surface of the adherend.

2. The adhesive application apparatus according to claim 1 , wherein:
the ultraviolet irradiation unit includes:
an ultraviolet light source; and
an ultraviolet transmission part for transmitting the ultraviolet light generated by the ultraviolet light source; and
the adhesive is irradiated with the ultraviolet light transmitted by the ultraviolet transmission part along the mounting surface.

3. The adhesive application apparatus according to claim 2 , wherein:
the ultraviolet transmission part includes:
a first ultraviolet transmission path; and
a second ultraviolet transmission path to which the ultraviolet light generated by the ultraviolet light source is transmitted via the first ultraviolet transmission path; and
the second ultraviolet transmission path has a value of refractive index which is closer to that of the adhesive, when compared to that of the first ultraviolet transmission path with respect to that of the adhesive.

4. The adhesive application apparatus according to claim 2 , wherein an ultraviolet shielding plate is provided to a surface, orthogonal to the mounting surface, of the ultraviolet transmission part.

5. The adhesive application apparatus according to claim 1 , further comprising an ultraviolet absorbing layer that absorbs ultraviolet light at an inner surface of the adhesive dosing unit.

6. The adhesive application apparatus according to claim 1 , further comprising an adhesive pipe for feeding the adhesive to the adhesive dosing unit, wherein the adhesive pipe includes a part that extends along the mounting surface.

7. The adhesive application apparatus according to claim 3 , wherein an ultraviolet shielding plate is provided to a surface, orthogonal to the mounting surface, of the ultraviolet transmission part.

8. The adhesive application apparatus according to claim 2 , further comprising an ultraviolet absorbing layer that absorbs ultraviolet light at an inner surface of the adhesive dosing unit.

9. The adhesive application apparatus according to claim 3 , further comprising an ultraviolet absorbing layer that absorbs ultraviolet light at an inner surface of the adhesive dosing unit.

10. The adhesive application apparatus according to claim 4 , further comprising an ultraviolet absorbing layer that absorbs ultraviolet light at an inner surface of the adhesive dosing unit.

11. The adhesive application apparatus according to claim 2 , further comprising an adhesive pipe for feeding the adhesive to the adhesive dosing unit, wherein the adhesive pipe includes a part that extends along the mounting surface.

12. The adhesive application apparatus according to claim 3 , further comprising an adhesive pipe for feeding the adhesive to the adhesive dosing unit, wherein the adhesive pipe includes a part that extends along the mounting surface.

13. The adhesive application apparatus according to claim 4 , further comprising an adhesive pipe for feeding the adhesive to the adhesive dosing unit, wherein the adhesive pipe includes a part that extends along the mounting surface.

14. The adhesive application apparatus according to claim 5 , further comprising an adhesive pipe for feeding the adhesive to the adhesive dosing unit, wherein the adhesive pipe includes a part that extends along the mounting surface.
