【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、紫外線照射によつて光硬化性接着剤を硬化さ
せ、少なくとも２つの部品を接合させる紫外線照射接着
装置に関する。Description: TECHNICAL FIELD The present invention relates to an ultraviolet irradiation adhesive device that cures a photocurable adhesive by ultraviolet irradiation to bond at least two components.
［従来の技術］ 紫外線照射による接着は、接着される部品が置かれてい

囲気中に存在すると、光硬化性樹脂接着剤の硬化反応の
開始が阻害されるので、反応に要する時間が長くなる。[Prior Art] Bonding by UV irradiation depends on the atmosphere in which the parts to be bonded are placed. That is, when oxygen is present in the atmosphere during ultraviolet irradiation, the initiation of the curing reaction of the photocurable resin adhesive is hindered, and the time required for the reaction becomes long.

反応の促進を図つたものが知られている。As means for solving such problems, for example, JP-A-59-136371 (hereinafter referred to as known example 1), JP-B-57-13334 (hereinafter referred to as known example 2) and JP-B-57-49262 are disclosed. As shown in (hereinafter referred to as known example 3), it is known that the curing reaction is promoted by introducing an inert gas into the ultraviolet irradiation chamber to shield the components from oxygen in the atmosphere.

うにしている。Further, the irradiation of ultraviolet rays causes a considerable amount of heat to be generated, which causes the components to be deformed by excessive heat, and in some cases, the ultraviolet rays to be devitrified by unnecessary heat of the ultraviolet lamp. in this regard,
The known example 1 is not considered at all. In the known example 2, a cooling pipe is provided to cool the components. In the known example 3, the ultraviolet ray irradiating part in the inert gas atmosphere and the ultraviolet ray irradiating part in the air atmosphere are provided in parallel with each other, and the ultraviolet ray irradiating part in the air atmosphere is used for cooling.

の熱及び部品の冷却については何ら考慮されていない。[Problems to be Solved by the Invention] In the known example 1, since the inert gas is introduced into the ultraviolet irradiation chamber, and the forward path and the return path of the conveyor belt are arranged in the ultraviolet irradiation chamber, the conveyor belt is used. There is a problem that the number of openings is large and the amount of inert gas leaking in the ultraviolet irradiation chamber is large. Further, since the inert gas is supplied to the ultraviolet irradiation chamber, a large amount of inert gas is required from this point as well, which is very uneconomical. Furthermore, no consideration is given to the unnecessary heat of the UV lamp and the cooling of the components.

がある。In the known example 2, the inner chamber is provided inside the outer chamber, but the outer chamber and the inner chamber communicate with each other. Further, although a long plate-like component is sent in as it is, if the component is sent by a conveyor belt, it is considered that the structure is the same as that in the known example 1. Therefore, the known example 2 has the same problem as the known example 1. Further, the known example 2 has a problem in that the unnecessary heat of the ultraviolet lamp is not cooled and the ultraviolet rays are devitrified because only the parts are directly cooled by the cooling pipe. Further, since a liquid is used for cooling, the structure becomes complicated and it is necessary to provide a complete sealing mechanism to prevent water leakage.

いう問題点を有する。In the known example 3, the conveyor belt is in the atmosphere, and the lower part of the ultraviolet irradiation section is open, so that an even larger amount of inert gas is required as compared with the known examples 1 and 2. Further, since the ultraviolet ray irradiating part in the inert gas atmosphere and the ultraviolet ray irradiating part in the air atmosphere are provided in parallel, there is a problem that the device inevitably becomes large.

不要な熱は冷却される。Next, the operation will be described. 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 out from the nozzles 22 to 25, 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 the carry-in belt 40 and the delivery belt 41 are started. 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 via the cooling fins 20, and unnecessary heat of the ultraviolet lamp 31 is cooled.

れる。Therefore, when the photocurable adhesive 4 is applied on the body 2 by the applicator 42 and the watch case 1 having the glass 3 placed on the body 2 is placed on the carry-in belt 40, The wristwatch case 1 includes the carry-in belt 40 to the delivery belt 41.
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 recess 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 way, the wristwatch case 1 in which the glass 3 is joined 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.

いと共に、紫外線ランプ３１の不要な熱も冷却される。Thus, the inner chamber 11 is provided in the outer chamber 10, and the inner chamber 1
Since only the forward path of the conveyor belt 13 is provided in the inner chamber 1, the inner chamber 11 can be made very small, and the only parts communicating with the atmosphere are the carry-in approach 11a and carry-out approach 11b of the inner chamber 11. That is, the volume of the chamber into which the inert gas is introduced may be small, and since the portion where the inert gas leaks is small, the consumption amount of the inert gas is significantly reduced. Further, since the air flows through the air passage 12 formed outside the inner chamber 11 and the periphery of the ultraviolet lamp 31,
The inner chamber 11 is effectively cooled, the parts are not overheated, and unnecessary heat of the ultraviolet lamp 31 is also cooled.
