The ultraviolet irradiation unit 3 is substantially L-shaped in a side sectional view, and is provided on a movable portion 31 (movable pressing portion) provided on the vertical portion 21 b of the base portion 21 so as to be vertically movable, and on a lower surface of the horizontal portion 31 a of the movable portion 31. Two attached ultraviolet light emitting diodes (UV-LED) 32 and a pressing portion 33 (movable pressing portion) disposed between the two ultraviolet light emitting diodes 32 are provided.
The movable portion 31 is configured to be vertically movable by a slide mechanism, a lock mechanism, and a return spring (not shown) and to be locked at the lower end position of the vertical portion 21b of the base portion 21. A plurality of wires 34 connected to the ultraviolet light emitting diodes 32 are arranged inside the movable portion 31, and terminal portions 35 are attached to the lower ends of the wires 34. The terminal portion 35 protrudes from the lower end surface of the vertical portion 31b of the movable portion 31. Therefore, when the movable portion 31 moves downward along the vertical portion 21b of the base portion 21 and contacts the base end portion of the vertical portion 21b, the distal end portion of the terminal portion 35 is substantially the same as the lower surface of the horizontal portion 21a of the base portion 21.

Further, the contact part 52 is connected to a power supply part provided separately from the base part 5 by wiring.
Therefore, the terminal portion 35 is brought into conduction by contacting the contact portion 52, and the ultraviolet light emitting diode 32 emits ultraviolet irradiation light.

  Further, the power supply unit has a controller (energization control means) (not shown) that performs ON / OFF control of energization to the wiring 34. The controller performs ON / OFF control of the energization to the wiring 34 based on the ON / OFF operation of the energization switch by the operator.

Next, the operation of the ultraviolet irradiation device 100 having the above configuration will be described.
First, for the jig 4, the workpiece 23 is inserted into the recess 22 a of the workpiece holding unit 22, and then the component 1 is inserted into the recess 23 a of the workpiece 23. Next, from the open state in which the movable part 31 has moved to the upper end side of the vertical part 21b of the base part 21 as shown in FIG. 1A, the movable part 31 is moved to the base part 21 as shown in FIG. It moves downward along the vertical part 21b until it reaches the horizontal part 21a of the base part 21. Accordingly, the movement of the movable portion 31 is fixed by being locked by the lock mechanism. At this time, the upper surface of the component 1 is pressed toward the workpiece 23 by the pressing portion 33 and the component 1 is securely fixed so as not to be displaced in the recess 23a. Further, the terminal portion 35 protruding from the lower end portion of the movable portion 31 is substantially flush with the lower surface of the horizontal portion 21 a of the base portion 21.

Thereafter, the worker applies the ultraviolet curable adhesive S to the component 1 and installs the jig 4 that has been prepared on the jig 51. As a result, the terminal portion 35 comes into contact with the contact portion 52 exposed in the concave portion 51a of the receiving jig 51 to be in a conductive state.
Next, the operator turns on the switch of the power supply unit to start energization by the controller, and energizes the ultraviolet light emitting diode 32 through the wiring 34, the contact unit 52, and the terminal unit 35. As a result, the ultraviolet light emitting diode 32 irradiates the component 1 with ultraviolet irradiation light. After the ultraviolet light curable adhesive S applied to the component 1 is cured after irradiation for a predetermined time or accumulated light amount, the jig 4 is taken out from the receiving jig 51.
Finally, in the removed jig 4, the movable portion 31 locked by the lock mechanism is unlocked, and the movable portion 31 is moved upward along the vertical portion 21 b of the base portion 21.

Then, the energization of the power supply unit is controlled by the energization control means, so that the component 1 held by the work 23 of the jig 4 is irradiated with ultraviolet rays from the ultraviolet light emitting diode 32. As a result, the ultraviolet curable adhesive S applied to the component 1 can be cured.
Thus, since the ultraviolet light emitting diode 32 is provided in the jig 4 and the irradiation apparatus and the jig are not separated as in the prior art, the apparatus 100 can be downsized, the installation cost is low, and even in a narrow space.
