The present invention relates to a curing apparatus and method for a photosensitive resin binder.

Today, resin adhesives (hereinafter referred to as resins) adhesives such as epoxy resin materials are widely used to bond various types of parts. One class of such adhesives is a mixture of two different materials in liquid or paste form that cure after some time. The time is determined by several factors but basically depends on the curing time and the type of material used as the binder composition. In these two liquid forms of resin binder, each constituent liquid has a very long shelf life before mixing with the other liquid. However, once mixing is achieved, the mixture must be used for a short time, ie before the mixture is cured. This is because such materials have a very short "pot life" after mixing. As a 2nd classification of resin adhesive, a photosensitive resin adhesive is mentioned. Such a photosensitive resin adhesive is used as a liquid and is held in a liquid state until light having a wavelength in a specific region, that is, ultraviolet ray, is cured, and curing starts when the ultraviolet ray is irradiated. By using such a photosensitive resin adhesive, not only can the adhesive consumption be reduced as compared to the adhesive using two liquid materials, but also two or more parts of the components through which the light is transmitted to adhere to the watch case, for example. The advantage is that it can be used very effectively to bond further parts.

However, the use of the photosensitive resin binder until now is limited by the fact that the UV irradiation for a long time is required to completely cure the adhesive layer, the production rate is lowered and the temperature of the component to be bonded during the curing time rises . In addition, the use of a conventional type of device for curing the photosensitive resin binder requires additional curing time due to the effects of oxygen and water vapor in the local environment during the curing process, as well as the need for post-curing photosensitive resin bonding layers. The degree of curing is not complete, and as a result, the gas produced by the curing reaction continuously for a long time is released from the photosensitive resin binder layer. This gas provides a selective etching action on any type of metal layer, such as a plated metal plate layer generally formed on a watch face, thus limiting the use of such photosensitive resin adhesives in attaching the watch glass to the watch case. That is, due to the corrosion of the surface of the number plate that the user sees, the watch is not properly received after manufacture.

In addition, the rise of the component to be bonded during the curing process irradiated with ultraviolet rays makes it impossible to use the photosensitive resin binder in bonding a component composed of a material such as plastic having a low resistance to heat. Therefore, the scope of application of this type of photosensitive resin binder has been very limited until now. The present invention overcomes the problems caused in the related art by using such a photosensitive resin bonding agent and broadens its application range. This is accomplished by extracting oxygen and water vapor from the atmosphere from the atmosphere of the part to be bonded while the photosensitive resin binder is cured.

SUMMARY OF THE INVENTION The present invention provides an apparatus for curing a photosensitive resin binder for bonding a component of a component assembly comprising at least two components each other at adjacent connections, the apparatus comprising: radiating means for emitting light at a wavelength in the ultraviolet region; Oxygen from the atmosphere of each photosensitive resin binder connection while the adhesive and the carrier means for transporting each component combination to cure ultraviolet light to the photosensitive resin binder connection to effectively cure the photosensitive resin binder for a predetermined time. It is provided with a means for extracting.

1 is a simplified vertical cross-sectional view of a device of the conventional type for curing a bond formed of a photosensitive resin bond. The component combination 18 to be joined under the inlet chute of FIG. 1 falls on the conveyor belt 14 at regular intervals. Each component combination 18 is composed of two or more components with a photosensitive resin binder layer disposed between the positions to be joined. This component combination tax 18 is composed of two or more components with a photosensitive resin binder layer disposed between the positions to be bonded. This component combination 18 is transported by the conveyor belt 14 at regular intervals along the conveyor belt 14 through the inlet at the cover 12 of the ultraviolet irradiation chamber 8. The ultraviolet lamp 10 is provided in the ultraviolet irradiation chamber 8 which directs the ultraviolet light 11 to the top surface 16 of the conveyor belt 14 to emit ultraviolet light to each component combination 18. Curing the photosensitive resin binder layer in the component assembly is performed as described above, and the component assembly 20 after such curing treatment exits on the conveyor belt 14 through the outlet 26 of the cover 12 and then exits the chute ( 22) Falls down.

In this prior art device, the curing action of the photosensitive resin binder takes place in the radiation cross section 17 in the irradiation chamber 8. Although the device is surrounded by the cover 12, the photosensitive resin binder layer on the component assembly to be joined by not sealing the inside of the irradiation chamber 8 from air is contained in the air and the oxygen in the air in the irradiation chamber 8 during the curing treatment by ultraviolet rays. Exposed to steam. These oxygens and vapors have a seriously bad effect on the ultraviolet curing action, and considerably prolong the time to be emitted before the curing process of the resin bonds is terminated. As a result, a relatively long time is required to cure the photosensitive resin binder using such a conventional apparatus. This long treatment period is solved by advancing the conveyor belt 14 sufficiently slowly or by continuously radiating ultraviolet light to the jet or more. However, as a result of prolonged exposure of the component assembly to be bonded to ultraviolet light, the component assembly is raised to actual temperature. This method is therefore only applicable to components with high thermal resistance and is generally unsuitable for bonding materials such as plastics. In addition, the productivity of the bonding treatment is low in terms of the time at which radiation should be used. This factor is the main reason why such photosensitive resin binders are not widely used to date.

It is possible to increase the radiation intensity of the ultraviolet light to be applied without prolonging the time emitted to the component combination to be joined. However, this treatment results in an increase in the temperature of the components to be combined.

FIG. 2 shows that the glass 28 of the watch is made of the watch case by the photosensitive resin binder layer 32 while the photosensitive resin binder layer 32 is cured using a conventional ultraviolet curing device such as the curing device of FIG. 3) A vertical cross-sectional view of the periphery of the wrist watch that is coupled to it. In general, since prolonged radiation causes extremely low productivity, the curing treatment by such a device is performed by radiating ultraviolet light for 20 seconds. With this short spinning time, the outer peripheral portions 34, 36 of the photosensitive resin binder layer 32, ie, the layer portions exposed to air, remain in an incompletely cured state even after the curing treatment. One of these outer peripheral portions 34 is exposed to the outside of the watch while the other peripheral portion 36 is embedded in the wristwatch between the inner surface of the watch glass 28 and the top surface 40 of the scale plate 38. That is, the outer peripheral portion 34 serves to seal the inside of the watch.

When the thickness of the uncured outer peripheral portions 34 and 36 of the photosensitive resin binder layer 32 is set to W, the ultraviolet radiation intensity applied to the photosensitive resin binder layer 32 which is the cured layer is set to B. , If the partial pressure of oxygen in the surrounding air is PO can be expressed as follows.

Where K is a coefficient determined by the duration of ultraviolet radiation and other various curing conditions. If these other conditions are constant, the coefficient K decreases with increasing radiation duration. The thickness of the outer peripheral portions 34 and 36 that are not cured after the curing by ultraviolet rays is more and more affected by the ultraviolet radiation energy and the partial pressure of the surrounding oxygen as the ultraviolet radiation time increases. Therefore, there are basically three factors that affect the ultraviolet curing treatment. In the prior art, only two of these factors have been focused: the influence of ambient oxygen on the curing process is very important, but the focus has been on the radiation intensity and duration of radiation. The curing process is slowed not only by oxygen in the air but also by water vapor in the air during the curing period.

When the watch glass of the wrist watch is joined using the ultraviolet curing method, the uncured or partially uncured portion of the photosensitive resin binder such as the outer peripheral portions 34 and 36 of FIG. It remains and serious problems arise. In other words, the hardening action continues within this uncured portion when the watch is stored (although it persists at a relatively slow rate). As a result, the gas produced by the curing reaction is released from the outer surface portion 36 of FIG. 2 and retained inside the sealed wrist watch. If the upper end 40 of the number plate 38 consists of a generally used metal plate, this gas optionally corrodes the upper end 40. Because of the resulting corrosion, after some time of storage, the appearance of the wrist watch changes dramatically, and the marketability actually decreases to zero. This is a very serious problem that occurs in the prior art.

It is an object of the present invention to produce oxygen and water vapor in the ambient atmosphere of the curing treatment during the ultraviolet irradiation curing of the photosensitive vertical adhesive liquid and to produce a resin that is completely cured by the curing treatment for only a very short duration of ultraviolet irradiation required to complete the curing. Remove the adhesive. In this way the ratio of producing ultraviolet radiation curing with the method of the present invention is much greater than in the prior art, eliminating the problem of excessive heating of the bonded components. Further, since the photosensitive resin adhesive liquid that can be realized is completely cured, the problem of dissipating the corrosive gas to the outside in the photosensitive resin adhesive liquid after curing is also eliminated, so the present invention is very suitable for manufacturing a watch.

A first embodiment of the ultraviolet irradiation device according to the present invention will now be described with reference to FIG. In Fig. 1, parts corresponding to those shown in the prior art example of Fig. 1 are indicated by corresponding reference numerals. Number 44 denotes a hydrogen inlet consisting of a nozzle connected to a source of hydrogen gas that does not contain water vapor (not shown), which inlet continues hydrogen into the interior of the ultraviolet irradiation chamber 45 at a rate of approximately 4 liters per minute. It is intended to flow. The ultraviolet irradiation chamber 45 is formed of a lid 42. Oxygen in the ultraviolet irradiation chamber 45 is replaced by nitrogen gas because dry nitrogen is generated in the ultraviolet irradiation chamber 45. The carriage carriage 14 continuously transports the cured component assembly 18 through the irradiation portion 17 of the ultraviolet irradiation chamber 45.

The ultraviolet radiation generated by the irradiation portion 17 is generated by a high voltage mercury lamp that constitutes the ultraviolet lamp 10 and generates an irradiation energy level of about 80 mW / cm ² at a wavelength in the region of 365 × 10 ^-9 m. Light of this wavelength provides the most effective curing for the photoresist adhesive liquid provided on the bonded component combination 41.

The conveying stand 14 is designed to minimize the size of each opening and the size of the openings 46 and 51 in which the lower part of the conveying stand 14 is embedded in the lid 42. 48) and the outlet opening 49 is located. In addition, the ratio of inputting nitrogen gas into the lid 42 through the inlet 44 is made such that the pressure in the lid 42 is higher than the atmospheric pressure. In this way the risk of air and oxygen flowing through the gap 46, 48, 49 or 51 inwards is eliminated. As a result of this, the component assembly 18 is completely separated from oxygen while the component assembly 18 is cured in the irradiated portion 17 by ultraviolet irradiation. In addition, the nitrogen introduced through the inlet nozzle 44 is almost dried and at a temperature of about 30 ° C., thereby removing the influence of moisture in the local atmosphere in the chamber 45 which severely interferes with the curing treatment.

The mold of the prior art, which is a device of the type shown in FIG. 11, for adhering the components shown in FIG. 2 to a carrier stage 14 moving at a speed of 100 cm / 200 seconds with the actual size of the ultraviolet irradiation chamber 8 If used, it is necessary to pass the bonded component combination through the irradiation chamber twice in succession. This takes 20 seconds for the entire curing time. However, using the device according to the invention as shown in FIG. 3, it is possible to achieve complete curing of the resin adhesive with only 4 seconds of curing time for this component combination. This is accomplished using the faster speed of the carriage stand 14, i.e. a single pass through 100 cm / 20 seconds and the required ultraviolet irradiation chamber. This therefore indicates that the productivity is increased by a factor of five compared to the prior art.

The nitrogen used in the apparatus according to the invention is conventional nitrogen, and since the nitrogen used in the curing process is very small, the cost of producing it using the apparatus according to the invention is not very important.

FIG. 4 shows a cross-sectional view of the assembly formed of the photoresist binder layer 32 between the watch glass 28 and the watch case 30, showing a view corresponding to FIG. 2 or a device after curing. Although the curing time is a very short period of about 4 seconds, the outer peripheral portions 34 and 36, which are the photoresist binder layer 32, are completely cured, and the release of the corrosive gas generated in the curing portion is insignificant. Thus, the problem that the surface 40 of the number plate 38 is corroded has been ruled out as described above. The test was performed on a wristwatch combined with a watch glass and a watch case with a photoresist binder layer cured by the device according to the present invention, wherein the wristwatch was subjected to illumination of 100, 000 rox equivalent to sunlight for one year. Even when left unchanged, no change occurred on the surface 40 of the number plate 38. It should be noted that, as described above, when the photoresist binder layer is cured using the apparatus according to the present invention, the adhesive strength between the glass and the watch case is shown to be extremely high withstanding a load of 15 kg.

5 shows a second embodiment of the present invention, which will be described with reference to the drawing. Reference numeral 58 denotes a plurality of transporters, which are operated by any device not shown in the figure and serve to transport the parts 18 to be joined. Each vehicle 58 is continuously transported to the lower position of the ultraviolet lamp 52 and stays there for a predetermined time. In the above embodiment, the ultraviolet lamp 52 essentially emits ultraviolet light having a wavelength of 365 × 10 ⁻⁹ m, which is such that the curing speed of the photoresist binder can be maximized. The reflector 54 serves to concentrate light from the lamp 52 to the lower part. Reference numeral 57 denotes a movable nozzle and is penetrated with a source of dry nitrogen gas. As each conveyor 58 moves to the lower position of the ramp 52, the movable nozzle 57 first moves upward to secure the base of the transportation vehicle and moves downward when the transportation equipment reaches its position to move nitrogen gas around the part. The spraying process is performed by the ultraviolet rays of the lamp 52 during the direct injection. In this manner, oxygen in the atmosphere is expelled around the component during the bonding process.

As the curing time (4 seconds in the case of the watch glass and watch case of FIG. 4) ends, the hardened part 20 is moved to the right by the conveyer 58 after the nozzle is moved upward. The process then repeats with the next operation of the carrier 58.

6 shows another embodiment of the present invention in a vertical cross-sectional view, in which the conveyor belt 14 is disposed in a completely sealed chamber so that the sealed chamber is maintained in a nitrogen gas atmosphere. Reference numeral 60 denotes a cover, and forms an ultraviolet radiation portion 62 in which the ultraviolet lamp 10 is disposed, and the ultraviolet absorption portion 65 is a position where the conveyor belt 14 is disposed. The transparent partition 56 is fixed by the attachment device 67 between the ultraviolet radiation portion 62 and the ultraviolet absorption portion 65 and serves to isolate the radiation portion and the absorption portion. The fan 68 for discharging the pressurized air is installed at the upper portion of the ultraviolet radiation unit 62 to discharge the high temperature air from the radiation unit, and the low temperature sucks the air through the suction port 63. According to the method as described above, the ultraviolet rays are transmitted to the ultraviolet absorbing portion 65 through the terminal transparent partition 66. In other words, the radiation is directed to the upper portion 16 of the conveyor belt 14 through which the component is conveyed.

Reference numeral 70 denotes a suction chute, and the component 18 is positioned on the conveyor belt 14 toward the ultraviolet absorber 65 away from the hole 72 at regular intervals. The gas valve nozzle 80 is connected to a source of dry nitrogen gas so that nitrogen gas is inserted through the nozzle and the second nozzle 82, so that the pressure under the nitrogen atmosphere is kept slightly higher than the pressure in the ultraviolet absorber 65. do.

Reference numeral 84 denotes a water-cooled cooling plate disposed directly below the upper portion 16 of the conveyor belt 14, which cools the structure 20 cured by ultraviolet radiation. The construct 20 then falls from the conveyor belt 14 to the exit ramp 76, and thus exits from the ultraviolet radiation receiving end face 65 through the hole 74. This curing apparatus minimizes the heating of the component during the curing process, thereby making it possible to apply photoresist adhesives to components formed of low thermal resistance materials such as plastic components.

In this embodiment, it was found that when the 120 mw / cm ² ultraviolet radiation energy incident on the upper portion of the conveyor belt 14 is incident, it is possible to maintain the temperature of the upper portion 16 at almost 60 ° C.

In the above-mentioned embodiments of the invention, the isolation of the construct from the air in the atmosphere during the curing process is carried out by removing the air surrounding the construct with an inert gas such as nitrogen. As a result, it may also be possible to remove oxygen from the construct during curing by ultraviolet radiation creating a vacuum. An embodiment of the present invention using such a method will be described with reference to FIG. Numeral 88 denotes the interior of the radiation compartment provided with an ultraviolet lamp 10 for directing ultraviolet radiation toward the upper portion of the conveyor belt 14 driven by the roller 86. Numeral 89 denotes an air extraction outlet connected to a vacuum pump (not shown in the drawing) which creates a vacuum inside the radiation compartment 88. The outer conveyor belt 98 conveys the transport container 96 toward the front compartment 96 with the components 18 pre-positioned and bonded (by manual or automatic means) at equal intervals to each transport container 96. Do what you do.

As in the previous embodiment, each component has a layer of gold photoresist adhesive that is attached to each other. Reference numeral 102 denotes an inlet hole of the front compartment 94, and reference 103 denotes a gate valve that can be opened or sealed to seal the seal to allow entry of the container 96. Reference numeral 100 denotes a conveyor belt disposed inside the front compartment 94. The air extraction outlet 95 of the front compartment 94 is connected to a vacuum pump. Reference numeral 104 denotes the exit hole of the front compartment 94, and 105 is lowered to isolate the front compartment 94 from the radiation compartment 88 or from the front compartment 94 to the radiation compartment 88. Indicate a gate valve that can be raised to allow passage of the carrier vessel. Reference numeral 92 denotes an outlet hole of the radiation compartment 88, reference numeral 93 denotes a gate valve, and reference numeral 108 denotes an entry hole of the outlet compartment 106. Gate valve 93 may be raised to open apertures 92 and 108 or may be lowered to isolate radiation compartment 88 from outlet compartment 106. Reference numeral 107 denotes an air extraction outlet of the outlet compartment 106 connected to the vacuum pump. The conveyor belt 110 is provided inside the exit compartment 106. The outlet hole 112 of the outlet compartment 106 may be opened or sealed by the up and down gate valve 114. Reference numeral 116 denotes a secondary conveyor belt for delivering the construct 20 after the curing process.

The operation of these devices is as follows. The air pressure inside the radiation compartment 88 is continuously maintained in a high vacuum state. Initially, assuming that the gate valves 105, 93, and 114 are both in a closed state, and when air is removed from the radiation compartment 88 and the exit compartment 106, the pressure inside the front compartment 94 is at atmospheric pressure. Up to the gate valve 103 is raised. At this time, the transporter 96 is carried by the outer conveyor belt 98 and the conveyor belt 100 enters the front compartment 95 through the hole 102. At this time, the gate valve 103 is closed and the air pressure in the front compartment 94 drops to a very low value to make a vacuum level of 0.1 to 1 Tori Cherry. When the pressure on both sides of the gate valve 105 is about the same, the gate valve 105 is opened and the conveyer 96 is carried by the conveyor belt 100, and the conveyor belt 14 passes through the holes 104 and 90 to the irradiation chamber ( 88) and placed in the center of the room under the ultraviolet lamp (10). At this time, curing of the photosensitive resin binder is performed by ultraviolet rays for a predetermined time, and the gate valve 93 is opened. In this case, the transporter 96 is carried by the conveyor belts 14 and 110 and goes from the irradiation chamber 88 to the exit chamber 106. At this time, the gate valve 93 is closed and the pressure in the outlet chamber 106 is raised to the atmospheric pressure level. At this time, the outlet gate valve 114 is opened and the transporter 96 is transported out of the outlet chamber 106 by the conveyor belts 110 and 116.

In this way, the operation of the valve is made smoothly and quickly and the constant vacuum is maintained in the irradiation chamber 88 by ensuring that the air pressure on each gate valve side is equal before the valve is opened or closed. In this way, high productivity is achieved.

It has been found that the ultraviolet level of 80mw / cm ² as measured on the upper side of the upper portion 16 of the conveyor belt 14 is satisfactory in such a device. In the examples of wristwatch case and cigar glass combinations described above, it has been found that a single curing operation for 5 seconds in the irradiation chamber 88 is sufficient for efficient complete curing of the photosensitive resin binder. In addition, the curing rate is increased not only by the separation of the photosensitive resin binder from the atmospheric oxygen and water during the curing process, but also due to the high vacuum in the surroundings where the curing is performed, the gas released as a result of the curing reaction is rapidly removed from the numerical layer, thereby curing. The above-mentioned problems caused by subsequent degassing from the photosensitive resin binder layer thus obtained are completely eliminated.

In the above description of the preferred embodiment, the present invention can be used for bonding the photosensitive resin binder by ultraviolet rays, and mass production and high productivity can be achieved. The advantages of the photosensitive resin binder are fully developed, thus eliminating the problems or waste associated with the use of conventional two-mixed synthetic resin binders, which result in very short potlife of the material after mixing. As the photosensitive resin binder, the bonding material remains in a completely liquid state indefinitely until it is subjected to ultraviolet rays, and thus the above problems caused by the prior art method of synthetic resin bonding are effectively solved. In addition, ultraviolet irradiation only needs to be carried out for a very short time, so that the temperature rise of the material during the curing process is maintained at a low level due to the moderate intensity of the radiation energy incident on the bonded material, and thus, The same material can be effectively bonded since ultraviolet irradiation of the photosensitive resin binder is used.

Although the present invention has been described above with reference to particular embodiments, it will be appreciated that various changes and modifications may be made to the embodiments, which are within the scope of the claims.
