As an example, as shown in FIG. 4, the case of the wristwatch case 1 in which the body 2 and the glass 3 are joined with the photocurable adhesive 4 will be described. When the ultraviolet irradiation adhesive device is started, an inert gas is blown from the nozzles 22 to 25, and the ultraviolet lamp 31 is turned on, and at the same time, the exhaust fan and the intake fan 3 in the exhaust part 33a.
4,35 start to turn. When the inert gas is blown out from the nozzles 22 to 25, the inside of the inner chamber 11 becomes an inert gas atmosphere. When the oxygen concentration falls below a certain value, a signal is output from the oxygen concentration sensor 21, and this signal stops the ejection of the inert gas from the purge nozzle 25 and starts the carry-in belt 40 and the delivery belt 41. When the exhaust fans and the intake fans 34 and 35 start to rotate, air is sucked into the outer chamber 10 through the air intake ports 10a and 10b. This air passes through the air passage 12 between the outer chamber 10 and the inner chamber 11, is guided to the exhaust duct 33, and is discharged to the outside from the exhaust portion 33a. Due to this air flow, the inner chamber 11 is cooled through the cooling fins 20, and the ultraviolet lamp 31
The unnecessary heat of is cooled.

It is placed on the conveyor belt 13 via. Then, the wristwatch case 1 is conveyed by the conveyor belt 13 from the carry-in approach 11a to the carry-out approach 11b through the inside of the inner chamber 11. Since the inner chamber 11 is in an inert gas atmosphere as described above, the photocurable adhesive 4 is irradiated with ultraviolet rays from the ultraviolet lamp 31 in a state where oxygen is completely blocked,
It cures quickly. The conveyor belt 13 is made of mesh,
Since the first and second nozzles 23 and 24 blow the inert gas from the lower surface of the conveyor belt 13 toward the upper surface thereof, the oxygen accumulated in the concave portion inside the wristwatch case 1 is also blown off. As a result, oxygen is completely blocked also at the inner end portion 4b of the photocurable adhesive 4, so that the inner end portion 4b is also rapidly cured. In this manner, the wristwatch case 1 in which the glass 3 is bonded to the body 2 via the photo-curable adhesive 4 is carried out from the carrier belt 13 through the seat 44 to the carry-out belt 43.

ルト４０が始動する。When the oxygen concentration in the inner chamber 11 exceeds a certain value during operation, a signal is output from the oxygen concentration sensor 21, the purge nozzle 25 is turned on, and a large amount of inert gas is blown out. Further, when the oxygen concentration exceeds the predetermined limit abnormally, an alarm sound is emitted and the carry-in belt 40 is stopped. Then, when the oxygen concentration in the inner chamber 11 falls below a certain limit, a signal is output again from the oxygen concentration sensor 21, the ejection of the inert gas from the purge nozzle 25 is stopped, and the carry-in belt 40 is started.

する紫外線照射接着装置。1. A photocurable composition comprising at least two parts which are superposed with a photocurable adhesive and are sent into an ultraviolet irradiation chamber by means of a mesh conveyor belt, and are irradiated by an ultraviolet lamp disposed in the ultraviolet irradiation chamber. In the ultraviolet irradiation adhesive device for curing the adhesive, an inlet nozzle is provided at the inlet of the carry-in approch so that an inert gas is ejected from the lower surface of the transfer belt to the upper surface of the transfer belt to the lower surface of the forward path of the mesh transfer belt. The ultraviolet irradiation adhesive device is characterized in that nozzles are respectively arranged on the carry-in approach side in the irradiation chamber so that oxygen in the concave portion of the component formed on the surface facing the upper surface of the conveyor belt can be removed.
