Abstract

Hardening of a primary liquid ingredient and a secondary liquid ingredient which have been discontinuously disposed on platy works is initiated by merely stacking the platy works.  The opposed surfaces are thereby bonded to each other without fail. Two platy works (1 and 2) are stacked, whereby a primary liquid ingredient (3a) and a secondary liquid ingredient (3b) which have been dispersedly disposed are spread and connected to each other to form a two-liquid mixed part (3c).  The primary liquid ingredient (3a) and secondary liquid ingredient (3b) which have mixed begin to harden, whereby the opposed surfaces (1a and 2a) of the platy works (1 and 2) are bonded.

Description

Bonding structure, manufacturing method thereof, and workpiece bonding apparatus

In the present invention, for example, a flat panel display (FPD) such as a liquid crystal display (LCD), an organic EL display (OLED), a plasma display (PDP), or a flexible display, or a sealing member such as an electronic circuit or a chip is covered with a cover plate. The present invention relates to a bonding structure made of, for example, an optical device such as a CMOS sensor and a CCD sensor, a MEMS device, and the like, a manufacturing method thereof, and a workpiece bonding apparatus for manufacturing the bonding structure.
Specifically, by laminating a pair of plate-like workpieces arranged to face each other, a bonding structure in which the plate-like workpiece is bonded by an adhesive previously applied to the opposite surface of the plate-like workpiece, and The present invention relates to a manufacturing method and a workpiece laminating apparatus for manufacturing the manufacturing method.

Conventionally, as a method of manufacturing this type of liquid crystal display panel, a gap control material in which an ultraviolet curable resin and a gap material are mixed is formed on a first substrate, and an ultraviolet adhesive is dropped on the second substrate using a dispenser. A linear sealing material is formed in a predetermined pattern using a method, and the first substrate and the second substrate are bonded and pressed, and ultraviolet light is applied to the gap material controlling material for the liquid crystal display panel. There exists what hardens a sealing material (for example, refer patent document 1).

JP 07-225384 A (page 2-4, FIG. 2-8)

Using such a conventional method, an adhesive is dropped from a dispenser onto both or one of a pair of plate-like workpieces and arranged in a discontinuous state, and then discontinuous by pasting the two plate-like workpieces together. It is conceivable that a seal portion is formed by extending and bonding the adhesives to each other, and curing the seal portion by irradiation with ultraviolet rays to bond the two plate-like workpieces together.
However, when a one-component adhesive is used as the adhesive, external energy such as irradiation with light such as ultraviolet rays or heating is used to cure the seal portion sandwiched between the two plate-like works. Since it becomes necessary, it is not possible to bond the plate-like workpieces simply by superimposing them, and there is a problem that it takes time to paste the plate-like workpieces and increases the cost of the bonding structure.
Furthermore, in the workpiece laminating apparatus for manufacturing the laminating structure, it is necessary to provide external energy means such as irradiation with light such as ultraviolet rays and heating described above, so that the structure of the entire apparatus is complicated and the cost is increased accordingly. There was a problem of being up.
In addition, for example, when the plate-like workpiece is formed of a material that cannot transmit light such as ultraviolet rays, the one-component adhesive cannot be cured by the light transmission of the plate-like workpiece, and the plate-like workpiece is thermally deformed. In the case of forming with a plate-shaped workpiece, the one-component adhesive cannot be cured by heating the plate-shaped workpiece, that is, the allowable characteristics of the plate-shaped workpiece and the curing conditions of the adhesive need to match, and can be used. There was a problem that liquid adhesives had limitations.
By the way, the liquid material of the one-component adhesive itself is affected by the usage environment, and its viscosity increases with time, so it is likely to deteriorate. There was a problem of being troublesome.
Furthermore, if a one-component adhesive is accidentally attached to the equipment used by the workpiece laminating device, it will harden due to deterioration, and it will harden because there is a considerable amount of curing energy such as ultraviolet rays and heat in the usage environment. In the beginning, there is a problem of fixing as a foreign substance, and in order to remove the foreign substance, a special stripping agent or the like is required, and there is also a problem that it is difficult to completely remove the foreign substance.

An object of the present invention is to deal with such a problem.

Moreover, the manufacturing method of the bonding structure by this invention is a two-component mixed hardening type adhesive agent in which the main agent liquid and the auxiliary agent liquid are respectively applied to both or one of the opposing surfaces of a pair of plate-like workpieces arranged in an opposing manner. Dispersively arranged in a discontinuous manner so as not to contact each other, the two plate-like workpieces are overlapped, and the main agent liquid and the auxiliary agent liquid are extended and connected to each other and mixed.

The laminated structure according to the present invention having the above-described features is a two-component mixing unit in which the main agent solution and the auxiliary agent solution that are dispersed and distributed are connected to each other as the two plate-like workpieces are overlapped, and mixed. Since the main agent liquid and the auxiliary agent liquid start to cure and the opposing surface of the plate-like work is attached, the hardening of the discontinuous main agent liquid and auxiliary agent liquid is started only by overlapping the plate-like workpiece, and the opposing surface The two can be securely bonded to each other.
As a result, it is not necessary to apply external energy such as irradiation with light such as ultraviolet rays or heating in order to cure the adhesive, so that the manufacturing cost can be reduced.
Furthermore, since the main agent liquid and the auxiliary agent liquid are dispersedly arranged in a discontinuous manner, the main agent liquid and the auxiliary agent liquid have a great opportunity to come into contact with each other, and it is easy to achieve uniform mixing in a short time.
In addition, as the two plate-shaped workpieces are superposed, the main agent liquid and the auxiliary agent liquid are stretched and the interface is brought into contact with each other to form a two-component mixing part, so bubbles are generated like mixing by stirring. There is no need to defoam.

Furthermore, in the bonding structure described above, when the main agent liquid and the auxiliary agent liquid are distributed and arranged so as to face each other on both opposing surfaces of the plate-like work, the two plate-like works are overlapped. The opposing main agent liquid and the auxiliary agent liquid are in contact with each other and extend, and they are connected to each other to form a two-liquid mixing part, which is filled over the opposing surface of the plate-like workpiece, and at the same time, the mixed main agent liquid and Since the auxiliary agent liquid starts to cure and the opposing surface of the plate-like workpiece is attached, the discontinuous main agent liquid and auxiliary agent liquid can be reliably mixed and cured.

Furthermore, in the bonding structure described above, in the case where the main agent liquid and the auxiliary agent liquid are alternately distributed on one of the opposing surfaces of the plate-like workpiece, the two plate-like workpieces are overlapped alternately. The main agent liquid and the auxiliary agent liquid that are arranged in a distributed manner are brought into contact with each other, and they are connected to each other to form a two-liquid mixing portion that fills the opposing surface of the plate-like workpiece. Since the mixed main agent liquid and auxiliary agent liquid start to cure and the opposing surface of the plate-like workpiece is attached, the discontinuous main agent liquid and auxiliary agent liquid can be reliably mixed and cured.

In addition, the method for producing a bonded structure according to the present invention is based on the overlapping of both plate-like workpieces, the main agent liquid and the auxiliary agent liquid are stretched and connected to each other, and are cured by mixing these main agent liquid and auxiliary agent liquid. Is started and the opposing surfaces of the plate-like workpieces arranged in a distributed manner are affixed, so that the curing of the adhesive can be started and bonded only by overlapping the plate-like workpieces.
As a result, it is not necessary to provide external energy means such as irradiation with ultraviolet rays or heating in order to start curing the adhesive, so that the structure of the entire apparatus can be simplified and the cost can be reduced accordingly. .
Furthermore, since the main agent liquid and the auxiliary agent liquid are dispersedly arranged in a discontinuous manner, the main agent liquid and the auxiliary agent liquid have a great opportunity to come into contact with each other, and it is easy to achieve uniform mixing in a short time.
In addition, as the two plate-shaped workpieces are superposed, the main agent liquid and the auxiliary agent liquid are stretched and connected to each other by contacting their interfaces, so there is a risk that bubbles will be generated like mixing by stirring. There is no need for defoaming.
In addition, since the start of curing of the adhesive is controlled by the stacking of the plate-like workpieces, the curing of each adhesive is not started until the stacking of the plate-like workpieces is performed. It can also be removed completely, and it is easy to clean even if the adhesive is mistakenly attached to the equipment used in the work laminating apparatus.
Also, since the unmixed adhesive is applied, the adhesive liquid material itself is not easily affected by the usage environment, can be stored for a long time even at room temperature, and has a longer life than a one-component adhesive. Easy to handle.

Furthermore, in the manufacturing method of the bonded structure described above, the main agent liquid and the auxiliary agent liquid are applied to both of the opposing surfaces of the plate-like work so as to face each other, and the main agent is obtained by superimposing the two plate-like works. When the liquid and the auxiliary agent liquid are brought into contact with each other and extended along the opposing surface of the plate-like workpiece, the extension tips of the main agent liquid and the auxiliary agent liquid are connected to each other to form a one-component two-liquid mixing part and mixed. Since the main agent solution and the auxiliary agent solution start to be cured as a whole and the opposing surface of the plate-like workpiece is attached, the discontinuous main agent solution and auxiliary agent solution can be reliably mixed and cured.

Furthermore, in the method for producing a bonded structure described above, the main agent liquid and the auxiliary agent liquid are alternately applied to one of the opposing surfaces of the plate-like workpiece, and the two main plate liquids are overlapped to overlap the main agent liquid and the auxiliary agent solution. When the chemical solution is extended along the opposing surface of the plate-like workpiece and the extension tips of the main agent solution and the auxiliary agent solution are brought into contact with each other, the extension tips of the main agent solution and the auxiliary agent solution are connected to each other. Since the mixed main agent liquid and auxiliary agent liquid start to cure as a whole and the opposing surface of the plate-shaped workpiece is attached, the discontinuous main agent liquid and auxiliary agent liquid are mixed reliably. It can be cured.
Moreover, if the main agent liquid and the auxiliary agent liquid are alternately dispersed and arranged only on the opposing surface of the plate-like work arranged below in the overlapping process of both plate-like works, the plate-like work is performed from the coating process to the bonding process. Since the work does not need to be turned over or tilted, dripping of the main agent liquid and the auxiliary agent liquid applied thereto can be prevented, and mixing of the main agent liquid and the auxiliary agent liquid before bonding can be prevented by the liquid dripping.

Furthermore, in the method for producing a bonded structure described above, when the main agent liquid and the auxiliary agent liquid are respectively discharged in a predetermined amount toward the surface of the plate-like workpiece and applied in the form of dots, the main agent liquid and the auxiliary agent liquid are used. By adjusting the discharge amount of the liquid, the application diameter of the main agent liquid and the auxiliary agent liquid can be changed and it can be applied in the form of fine dots, so the main agent liquid and the auxiliary agent liquid are kept in shape by their surface tension. can do.
As a result, even if the direction of the plate-like workpiece to which the main agent liquid or the auxiliary agent liquid is applied is changed, the main agent liquid and the auxiliary agent liquid can be prevented from being mixed due to the liquid dripping.
Moreover, if the viscosity of the main agent liquid and the auxiliary agent liquid is lowered and discharged by heating, it can be applied in a finer dot shape, and after application, the temperature is lowered and the viscosity is increased, so that dripping does not easily occur.

Furthermore, in the method for producing a bonded structure described above, the space around the plate-shaped workpiece is reduced in pressure, and the two plate-like workpieces are overlapped in an environment of the reduced pressure to add the main agent liquid and the auxiliary agent liquid. In the case of mixing, since bubbles do not enter with the mixing of the main agent liquid and the auxiliary agent liquid, the main agent liquid and the auxiliary agent liquid can be mixed without bubbles.
As a result, it is not necessary to defoam the adhesive after laminating the plate-like workpieces, and the time required to complete the laminating can be shortened.

In addition, the workpiece laminating apparatus according to the present invention, as the two plate-like workpieces are overlapped, the dispersed main agent liquid and auxiliary agent liquid are stretched and connected to each other to form a two-component mixing unit. Since the agent solution starts to be cured and the opposing surface of the plate-like workpiece is attached, it is possible to start and cure the adhesive only by overlapping the plate-like workpiece.
As a result, it is not necessary to provide external energy means such as irradiation with ultraviolet rays or heating in order to start curing the adhesive, so that the structure of the entire apparatus can be simplified and the cost can be reduced accordingly. .
Furthermore, since the main agent liquid and the auxiliary agent liquid are dispersedly arranged in a discontinuous manner, the main agent liquid and the auxiliary agent liquid have a great opportunity to come into contact with each other, and it is easy to achieve uniform mixing in a short time.
In addition, as the two plate-shaped workpieces are superposed, the main agent liquid and the auxiliary agent liquid are stretched and connected to each other by contacting their interfaces, so there is a risk that bubbles will be generated like mixing by stirring. There is no need for defoaming.
In addition, since the start of curing of the adhesive is controlled by the stacking of the plate-like workpieces, the curing of each adhesive is not started until the stacking of the plate-like workpieces is performed. It can also be removed completely, and it is easy to clean even if the adhesive is mistakenly attached to the equipment used in the work laminating apparatus.
Also, since the unmixed adhesive is applied, the adhesive liquid material itself is not easily affected by the usage environment, can be stored for a long time even at room temperature, and has a longer life than a one-component adhesive. Easy to handle.

Further, in the work laminating apparatus described above, when both the main agent liquid and the auxiliary agent liquid are applied to both opposing surfaces of the plate-like work so that the main agent liquid and the auxiliary agent liquid face each other, By overlapping, the opposing main agent liquid and auxiliary agent liquid collide with each other and extend, and they are connected to each other to form a two-liquid mixing part that fills the opposing surface of the plate-like workpiece and simultaneously mixes them. Since the main agent liquid and the auxiliary agent liquid thus started to cure and the opposing surface of the plate-like workpiece is attached, the discontinuous main agent liquid and auxiliary agent liquid can be reliably mixed and cured.

Further, in the work laminating apparatus described above, both plates are applied to one of the opposing surfaces of the plate-like work so that the main agent liquid and the auxiliary agent liquid are alternately dispersed and arranged by the application means. The main work liquid and sub-agent liquid that are alternately distributed and extended each other, and the ends of the work are overlapped with each other to form a two-liquid mixing part. At the same time, the mixed main agent solution and auxiliary agent solution start to harden and the opposing surface of the plate-shaped workpiece is attached, so that the discontinuous main agent solution and auxiliary agent solution are mixed reliably. And can be cured.
Moreover, if the main agent liquid and the auxiliary agent liquid are alternately dispersed and arranged only on the opposing surface of the plate-like work arranged below in the overlapping process of both plate-like works, the plate-like work is performed from the coating process to the bonding process. Since the work does not need to be turned over or tilted, dripping of the main agent liquid and the auxiliary agent liquid applied thereto can be prevented, and mixing of the main agent liquid and the auxiliary agent liquid before bonding can be prevented by the liquid dripping.

Further, in the workpiece bonding apparatus described above, the application unit has a liquid fixed amount discharge machine, and when the main liquid and the auxiliary liquid are discharged in a fixed amount from the liquid fixed discharge machine, respectively, By adjusting the discharge amount from the liquid metering dispenser, the application diameter of the main agent liquid and the auxiliary agent liquid can be changed, and it becomes possible to apply fine dots, so that the main agent liquid and the auxiliary agent liquid are The shape can be maintained by surface tension.
As a result, even if the direction of the plate-like workpiece to which the main agent liquid or the auxiliary agent liquid is applied is changed, the main agent liquid and the auxiliary agent liquid can be prevented from being mixed due to the liquid dripping.
Moreover, if the viscosity of the main agent liquid and the auxiliary agent liquid is lowered and discharged by heating, it can be applied in a finer dot shape, and after application, the temperature is lowered and the viscosity is increased, so that dripping does not easily occur.

Further, the above-described workpiece laminating apparatus is configured such that the laminating machine forms a closed space capable of adjusting the atmospheric pressure around the plate-shaped workpiece, and superimposes both the plate-shaped workpieces in an environment where the closed space is decompressed. Thus, when forming the two-component mixing portion of the main agent solution and the auxiliary agent solution, the main agent solution 3a and the auxiliary agent solution 3b are mixed in an environment of a reduced pressure atmosphere, and bubbles are generated along with the formation of the two-component mixing portion 3c. The main agent liquid and the auxiliary agent liquid can be mixed in a bubble-free state without entering.
As a result, it is not necessary to defoam the adhesive after laminating the plate-like workpieces, so that the time required to complete the lamination of the plate-like workpieces can be shortened.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 to 4, a bonding structure A according to an embodiment of the present invention includes a pair of plate- like workpieces 1 and 2 that are arranged to be opposed to each other, and these plate- like workpieces 1 and 2. The two-component mixed curable adhesive 3 is applied to both or one of the opposing surfaces 1a and 2a.

The plate- like workpieces 1 and 2 are made of, for example, a glass substrate or PES (Poly-Ether) used in a flat panel display (FPD) such as a liquid crystal display (LCD), an organic EL display (OLED), a plasma display (PDP), and a flexible display. -Sulphone) or plastic resin substrate, or a cover plate such as a wafer or cover glass on which an electronic circuit or chip is applied, for example, an optical device or a MEMS device such as a CMOS sensor or a CCD sensor. is there.

The two-component mixed curing type adhesive 3 has an main agent liquid 3a and an auxiliary agent liquid 3b as main components, and is an adhesive that starts to cure by mixing the main agent liquid 3a and the auxiliary agent liquid 3b. is there.
Examples of the two-component mixed curable adhesive 3 include an epoxy adhesive, a second generation acrylic adhesive (SGA) polyurethane adhesive, and a silicon adhesive.
In addition, it is also possible to add a crosslinking accelerator or a curing catalyst to the two-component mixed curable adhesive 3 as an additive other than the main agent liquid 3a and the auxiliary agent liquid 3b.

Then, the main agent liquid 3a and the auxiliary agent liquid 3b that are uncured by the two-component mixed curable adhesive 3 are not in contact with each other or both of the surfaces 1a and 2a that are opposite surfaces of the plate- like workpieces 1 and 2. The dispersive arrangement is such that the two-component mixing unit 3c is formed by extending the main agent liquid 3a and the auxiliary agent liquid 3b and connecting them to each other by being applied in a non-continuous manner and by laminating the two plate- like workpieces 1 and 2 It is said.
That is, when the main agent liquid 3a and the auxiliary agent liquid 3b are overlapped with the two plate- like workpieces 1 and 2, the dispersed main agent liquid 3a and the auxiliary agent liquid 3b are extended so that the interfaces contact each other. They are connected to each other so as to become a two-component mixing part 3c.
In order to facilitate the extension of the main agent liquid 3a and the auxiliary agent liquid 3b, it is preferable to use one having a low viscosity (200 Pa · s = about 200,000 cP or less).

The total amount of the main agent liquid 3a and the auxiliary agent liquid 3b applied in a discontinuous manner to the opposing surfaces (surfaces) 1a, 2a of the plate- like workpieces 1, 2 is the main agent by overlapping both plate- like workpieces 1, 2 It is determined by the extended shape of the liquid 3a and the auxiliary agent liquid 3b and the gap G between the two plate- like workpieces 1 and 2 after bonding.

The application amount per one of the non-continuous main agent liquid 3a and the auxiliary agent liquid 3b is, for example, 1000 μg or less, specifically 10 μg to 100 μg. It is preferable that the hemispherical shape is maintained by the surface tension generated on the surfaces of the main agent liquid 3a and the auxiliary agent liquid 3b.
In this case, even if the plate- like workpieces 1 and 2 after application are moved so that the surfaces 1a and 2a thereof are inclined or turned over so that they face downward, the main agent liquid 3a and the auxiliary agent liquid 3b come into contact with each other. There is an advantage of not.

The application ratio of the main agent liquid 3a and the auxiliary agent liquid 3b is determined by the appropriate mixing ratio of the main agent liquid 3a and the auxiliary agent liquid 3b in the two-component mixed curing adhesive 3.
When the mixing ratio of the main agent liquid 3a and the auxiliary agent liquid 3b is 1: 1 as in the illustrated example, the main agent liquid 3a and the auxiliary agent liquid 3b are applied in a spot shape having substantially the same size, and the main agent liquid 3a and the auxiliary agent liquid 3b are applied. When the mixing ratio of the agent liquid 3b is 2: 1, the application amount of the main agent liquid 3a is set to be twice the application amount of the auxiliary agent liquid 3b, or the same amount facing the one auxiliary agent liquid 3b. The amount of the main agent liquid 3a is arranged twice.

Examples of the application of the main agent liquid 3a and the auxiliary agent liquid 3b include both the facing surfaces 1a and 2a of the plate- like workpieces 1 and 2 as shown in FIGS. 1 (a) and 2 (a) and 2 (b). In addition, the main agent liquid 3a and the auxiliary agent liquid 3b are dispersedly arranged so as to face each other when the two plate- like works 1 and 2 are overlapped.
That is, the uncured main agent liquid 3a and the auxiliary agent liquid 3b are applied to both the opposing surfaces 1a and 2a in the same fine dot pattern facing each other.

In the illustrated example, only the main agent liquid 3a is applied to the surface 1a of the plate-like workpiece 1 arranged above, and only the auxiliary agent liquid 3b is applied to the surface 2a of the plate-like workpiece 2 arranged below. ing. Although not shown as another example, if the main agent liquid 3a and the auxiliary agent liquid 3b face each other when the two plate- like workpieces 1 and 2 are overlapped, respectively, the surface 1a of the plate-like workpiece 1 or the surface 2a of the plate-like workpiece 2 is respectively It is also possible to disperse the main agent liquid 3a and the auxiliary agent liquid 3b so as to coexist.

Further, in the illustrated example, as shown in FIGS. 2 (a) and 2 (b), the plate- like workpieces 1 and 2 are formed in a rectangular flat plate shape, and the main agent liquid 3a and the auxiliary liquid 3a and sub-substantially extend over substantially the entire facing surfaces 1a and 2a. The liquid agent 3b is distributed at regular intervals.
Although not illustrated as another example, the main agent liquid 3a and the auxiliary agent liquid 3b are formed only in the periphery of the opposing surfaces 1a and 2a formed in a rectangular shape so as to have a rectangular frame shape along the four sides of the opposing surfaces 1a and 2a. The main agent liquid 3a and the auxiliary agent liquid 3b may be distributed and arranged in a part of the opposing surfaces 1a and 2a so as to have an arbitrary shape such as a straight line or a curved line.
Moreover, it is also possible to disperse and arrange the main agent liquid 3a and the auxiliary agent liquid 3b on the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2 formed in a shape other than a rectangle so as to have an arbitrary shape.

In such an embodiment, as shown in FIG. 1 (b), due to the overlapping of the two plate- like workpieces 1 and 2, the opposing main agent liquid 3a and the auxiliary agent liquid 3b abut each other and start mixing, It extends along the opposing surfaces 1a and 2a.
Subsequently, as shown in FIG. 1 (c), when the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2 further approach each other, the main agent liquid 3a and the auxiliary agent liquid 3b are further mixed and simultaneously opposed. The leading ends of the main agent liquid 3a and the auxiliary agent liquid 3b extending along the surfaces 1a and 2a are connected to each other to form a one-component two-liquid mixing portion 3c, and the whole of the main agent liquid 3a and the auxiliary agent liquid 3b is mixed. Start curing.

Thereafter, as shown in FIG. 1 (d), when the pressure between the opposing surfaces 1a, 2a of the plate- like workpieces 1, 2 is increased to a predetermined gap G, the two-liquid mixing part 3c is further extended, The two-liquid mixing part 3c extends and fills the desired shape over a predetermined area between the opposing surfaces 1a and 2a, and the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2 are attached in this state.
In the case where the main agent liquid 3a and the auxiliary agent liquid 3b are distributed at regular intervals over substantially the entire rectangular opposing surfaces 1a and 2a as in the illustrated example, the two parts shown in FIGS. As indicated by the dotted line, the two-liquid mixing part 3c extends into a substantially rectangular shape and fills up.
Although not shown, when the main agent liquid 3a and the auxiliary agent liquid 3b are dispersedly arranged in a rectangular frame shape along the peripheral edges of the rectangular opposing surfaces 1a and 2a, the two-liquid mixing unit 3c extends in a frame shape. A sealing space for enclosing liquid crystal or the like is formed inside.
As a result, the discontinuous main agent liquid 3a and auxiliary agent liquid 3b are reliably mixed only by overlapping the two plate- like workpieces 1 and 2, and curing is started, and the opposing surfaces 1a and 2a are securely bonded to each other. The combined structure A is obtained.

As other application examples, as shown in FIGS. 3 (a) and 4 (a) (b), the main agent liquid 3a and the auxiliary agent are applied to one of the opposing surfaces 1a, 2a of the plate- like workpieces 1, 2.

Embodiments of the present invention will be described below with reference to the drawings.

In the first embodiment, as shown in FIGS. 6A to 6C, an upper holding plate 21 and a lower holding plate 22 are disposed in divided chambers 26a and 26b that can be divided in the vertical direction. The divided chambers 26a and 26b are closed by the operation of the opening / closing drive unit 27a, and the plate- like workpieces 1 and 2 are overlapped after the closed space S partitioned therein reaches a predetermined degree of vacuum. The case where the closed space S is an air release type vacuum bonding machine 20 that is open to the atmosphere is shown.

If necessary, either one or both of the divided chambers 26a and 26b are supported so as to be adjustable in the horizontal direction (XYθ direction), or any of the upper and lower holding plates 21 and 22 with respect to the divided chambers 26a and 26b. It is preferable to support such that one or both of them can be adjusted and moved in the horizontal direction (XYθ direction).

In the illustrated example, only the upper divided chamber 26 a provided with the upper holding plate 21 can reciprocate so as to approach or separate in the vertical direction (Z direction) with respect to the lower divided chamber 26 b provided with the lower holding plate 22. And is opened and closed by the operation of the opening / closing drive unit 27a.
With respect to these upper and lower divided chambers 26a, 26b, either one or both of the upper holding plate 21 and the lower holding plate 22, in the illustrated example, only the upper holding plate 21 is supported by the elevating drive unit 23 so as to be movable up and down. After the opening and closing of the divided chambers 26a and 26b, the upper plate-like workpiece 1 is moved closer to the lower plate-like workpiece 2a.

As another example, by providing the upper and lower holding plates 21 and 22 integrally with the divided chambers 26a and 26b, the raising and lowering drive unit 23 of the upper and lower holding plates 21 and 22 and the opening and closing drive unit 27a of the divided chambers 26a and 26b are integrated. It is also possible to make it.
In this case, for example, by making use of elastic deformation of the annular seal portion 28 such as an O-ring provided between the divided chambers 26a and 26b, the divided chambers 26a and 26b are moved closer to each other after being closed. The plate- like workpieces 1 and 2 can be overlapped.

In addition, one or both of the divided chambers 26a and 26b is provided with a pressure adjusting unit 29 that penetrates the inside and outside of the divided chamber 26a and 26b, and controls the operation of the pressure adjusting unit 29 by the control unit 25. By exhausting the internal gas from the closed space S in the closed divided chambers 26a and 26b to the outside, the pressure is reduced to a predetermined vacuum state, and conversely, the external gas is supplied to the inside. The internal pressure of the closed space S is returned to the same state as the ambient pressure (atmospheric pressure).

Further, in the case of the illustrated example, as shown in FIGS. 1 (a) and 2 (a) (b), examples of the application of the main agent liquid 3a and the auxiliary agent liquid 3b by the applying means 10 are as follows. The main agent liquid 3a and the auxiliary agent liquid 3b are dispersedly arranged on both the opposing surfaces 1a and 2a so as to face each other when the two plate- like workpieces 1 and 2 are overlapped.
As another example, as shown in FIGS. 3 (a) and 4 (a) (b), the main agent liquid 3a and the auxiliary agent liquid are provided only on one of the opposing surfaces 1a, 2a of the plate- like workpieces 1, 2. It is also possible to disperse and arrange 3b alternately.

Next, the manufacturing method of the bonding structure A by such a workpiece | work bonding apparatus is demonstrated according to process order.
First, as shown by the solid line in FIG. 6 (a), in a state where the divided chambers 26a and 26b are opened, a plate on which the main agent liquid 3a and the auxiliary agent liquid 3b are applied by the application means 10 to the inside by the work transfer means 24. The workpieces 1 and 2 are carried in, and the upper plate-like workpiece 1 is delivered to the holding surface 21a of the upper holding plate 21 by the holding means provided on the holding surfaces 21a and 22a of the upper and lower holding plates 21 and 22. The lower plate-like workpiece 2 is transferred to the holding surface 22a of the lower holding plate 22 and holds each of them.

Thereafter, as shown by a two-dot chain line in FIG. 6A, the open / close drive unit 27a is operated to close the divided chambers 26a and 26b, thereby forming a closed space S therein.
Vacuuming is started from the closed space S by the operation of the pressure adjusting unit 29 before or during the closing operation, and reaches a predetermined degree of vacuum.

Subsequently, as shown by the solid line in FIG. 6 (b), the upper and lower holding plates 21 and 22 are automatically moved closer to each other by the operation of the elevating drive unit 23, and move to the holding surfaces 21a and 22a. The held plate- like workpieces 1 and 2 are overlapped with each other through the pre-applied main agent liquid 3a and auxiliary agent liquid 3b.

Further, immediately before this superposition, the upper and lower holding plates 21 and 22 are adjusted and moved relative to the horizontal direction (XYθ direction) perpendicular to the superposition direction as necessary, thereby holding the plate It is also possible to align the workpieces 1 and 2 with each other.

As shown in the illustrated example, when the main agent liquid 3a and the auxiliary agent liquid 3b are dispersedly arranged on both the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2 so as to face each other, As a result of the superposition, the main agent liquid 3a and the auxiliary agent liquid 3b abut each other and start mixing, and at the same time, extend along the opposing surfaces 1a and 2a.
Subsequently, as shown by the two-dot chain line in FIG. 6B, when the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2 are further brought closer to each other, the main agent liquid 3a and the auxiliary agent liquid 3b are further mixed. At the same time, the leading ends of the main agent liquid 3a and the auxiliary agent liquid 3b extending along the opposing surfaces 1a and 2a are connected to each other to form a one-component two-liquid mixing portion 3c, which is used for mixing the main agent liquid 3a and the auxiliary agent liquid 3b. Accompanied with this, curing begins.

Here, as shown in FIG. 2 (a) (b) or FIG. 4 (a) (b), the main agent liquid 3a and the auxiliary agent liquid 3b are dispersed at regular intervals over substantially the entire surface of the rectangular opposing surface 2a. In the case of the arrangement, as shown by a one-dot chain line in FIG. 6 (c), when the pressure is applied until the gap G between the opposing surfaces 1a and 2a of the two plate- like workpieces 1 and 2 becomes a predetermined gap G, The mixing portion 3c extends and fills substantially the entire opposing surface 2a, and a sealing member such as a liquid crystal, an electronic circuit, or a chip is hermetically sealed therein.

Further, when the main agent liquid 3a and the auxiliary agent liquid 3b are dispersedly arranged in a rectangular frame shape along the peripheral edges of the rectangular opposing surfaces 1a and 2a, the two-liquid mixing portion 3c extends in a frame shape, A sealing space for enclosing liquid crystal or the like is formed in the.
For this reason, as shown by the solid line in FIG. 6C, the holding of the upper holding plate 21 is released to release the holding of the upper plate-like workpiece 1, and the pressure adjusting unit 29 is subsequently operated to divide the chamber. The closed space S in 26a, 26b is opened to the atmosphere, and a pressure difference is generated between the internal pressure and the internal pressure of the sealing member surrounded by the frame-like two-liquid mixing part 3c.
Due to the difference in pressure generated inside and outside of the sealed space, the plate- like workpieces 1 and 2 are pressed uniformly and compressed in a parallel state, and accordingly, the two-liquid mixing unit 3c is uniformly pushed over the entire circumference. The plate- like workpieces 1 and 2 are crushed and bonded in parallel, and the distance between them becomes a predetermined gap G.

After such a bonding process is completed, as shown by a two-dot chain line in FIG. 6C, the division chambers 26a and 26b are opened by the operation of the opening / closing drive unit 27a, and the holding means of the lower holding plate 22 is The holding of the plate-like workpiece 1 is released by the operation, and the plate- like workpieces 1 and 2 that have been bonded together are carried out from the inside of the divided chambers 26a and 26b by the workpiece transfer means 24.
Thereafter, the above-described operation is repeated.

Therefore, in the first embodiment shown in FIGS. 6A to 6C, the main agent liquid 3a and the auxiliary agent liquid 3b are placed in an environment where the closed space S that is the space around the plate- like workpieces 1 and 2 is in a predetermined vacuum degree. Since the two-liquid mixing part 3c is mixed, bubbles do not enter with the mixing of the main agent liquid 3a and the auxiliary agent liquid 3b.
Thereby, the main agent liquid 3a and the auxiliary agent liquid 3b can be mixed without bubbles, and it is not necessary to defoam from the two-liquid mixing part 3c after the plate- like workpieces 1 and 2 are bonded together. There is an advantage that time can be shortened.

In the second embodiment, as shown in FIGS. 7A to 7C, an inseparable chamber 26c is provided in place of the divided chambers 26a and 26b, and the door 26d can be opened and closed so as to cover the entrance / exit. The closed chamber-type vacuum bonding machine 20 is supported, and the door 26d is opened and closed by the operation of the opening and closing drive unit 27b, and the upper holding plate 21 and the lower holding plate 22 are disposed inside the chamber 26c. However, unlike the first embodiment shown in FIGS. 6A to 6C, the other configurations are the same as those of the first embodiment shown in FIGS. 6A to 6C.

In the illustrated example, only the upper holding plate 21 is supported by the elevating drive unit 23 so as to be movable up and down, and the upper plate-like workpiece 1 is moved closer to the lower plate-like workpiece 2a after the chamber 26c is closed. However, the upper holding plate 21 and the lower holding plate 22 may be moved closer to each other or only the lower holding plate 22 may be moved instead of this, as in the first embodiment.

Further, in the case of the illustrated example, the application examples of the main agent liquid 3a and the auxiliary agent liquid 3b by the applying means 10 are as shown in FIGS. The main agent liquid 3a and the auxiliary agent liquid 3b are alternately distributed on either one of the opposing surfaces 1a and 2a, for example, only on the lower plate-like workpiece 2.
As another example, as shown in FIG. 1A and FIGS. 2A and 2B, both plate- like workpieces 1 and 2 are superimposed on both opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2. It is also possible to disperse the main agent liquid 3a and the auxiliary agent liquid 3b so as to face each other.

Next, the manufacturing method of the bonding structure A by such a workpiece | work bonding apparatus is demonstrated according to process order.
First, as shown by the solid line in FIG. 7 (a), a plate-like shape in which the main agent liquid 3a and the auxiliary agent liquid 3b are applied by the application means 10 to the inside of the chamber 26c by the work transfer means 24 with the entrance of the chamber 26c opened. The workpieces 1 and 2 are carried in, and the upper plate-like workpiece 1 is delivered to the holding surface 21a of the upper holding plate 21 by the holding means provided on the holding surfaces 21a and 22a of the upper and lower holding plates 21 and 22, and the lower The lower plate-like workpiece 2 is transferred to the holding surface 22a of the holding plate 22 and holds each.

Thereafter, as indicated by a two-dot chain line in FIG. 7A, the door 26d closes the entrance / exit of the chamber 26c by the operation of the opening / closing drive unit 27b, and a closed space S is formed therein.
Vacuuming is started from the closed space S by the operation of the pressure adjusting unit 29 before or during the closing, and reaches a predetermined degree of vacuum.

Subsequently, as shown by the solid line in FIG. 7 (b), the upper holding plate 21 and the lower holding plate 22 are automatically moved closer to each other by the operation of the elevating drive unit 23, and the holding surfaces 21a and 22a are moved to the holding surfaces 21a and 22a. The held plate- like workpieces 1 and 2 are overlapped with each other through the pre-applied main agent liquid 3a and auxiliary agent liquid 3b.

Further, immediately before this superposition, the upper and lower holding plates 21 and 22 are adjusted and moved relative to the horizontal direction (XYθ direction) perpendicular to the superposition direction as necessary, thereby holding the plate It is also possible to align the workpieces 1 and 2 with each other.

As shown in the example, when the main agent liquid 3a and the auxiliary agent liquid 3b are alternately distributed only on one of the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2, for example, only the lower plate-like workpiece 2, By superimposing the two plate- like workpieces 1 and 2, the main agent liquid 3a and the auxiliary agent liquid 3b alternately distributed between the opposing surfaces 1a and 2a extend along the opposing surfaces 1a and 2a, respectively.
Subsequently, as shown by the two-dot chain line in FIG. 7 (b), when the opposing surfaces 1a, 2a of the plate- like workpieces 1, 2 further approach each other, the main agent liquid 3a that extends along the opposing surfaces 1a, 2a. And the tips of the auxiliary agent liquids 3b collide with each other, and they start to mix to form a one-component two-liquid mixing part 3c, and as a whole, the curing starts with the mixing of the main agent liquid 3a and the auxiliary agent liquid 3b. .

Here, as shown in FIG. 2 (a) (b) or FIG. 4 (a) (b), the main agent liquid 3a and the auxiliary agent liquid 3b are dispersed at regular intervals over substantially the entire surface of the rectangular opposing surface 2a. In the case of being arranged, if the pressure is applied until the gap G between the opposing surfaces 1a and 2a of the two plate- like workpieces 1 and 2 becomes a predetermined gap G, as shown by a one-dot chain line in FIG. The mixing portion 3c extends and fills substantially the entire opposing surface 2a, and a sealing member such as a liquid crystal, an electronic circuit, or a chip is hermetically sealed therein.

Further, when the main agent liquid 3a and the auxiliary agent liquid 3b are dispersedly arranged in a rectangular frame shape along the peripheral edges of the rectangular opposing surfaces 1a and 2a, the two-liquid mixing portion 3c extends in a frame shape, A sealing space for enclosing liquid crystal or the like is formed in the.
For this reason, as shown by the solid line in FIG. 7C, the holding of the upper holding plate 21 is operated to release the holding of the upper plate-like workpiece 1 and the chamber 26c is then operated by the operation of the pressure adjusting unit 29. The internal closed space S is opened to the atmosphere, and a pressure difference is generated between the internal pressure and the internal pressure of the sealing member surrounded by the frame-like two-liquid mixing part 3c.
Due to the difference in pressure generated inside and outside of the sealed space, the plate- like workpieces 1 and 2 are pressed uniformly and compressed in a parallel state, and accordingly, the two-liquid mixing unit 3c is uniformly pushed over the entire circumference. The plate- like workpieces 1 and 2 are crushed and bonded in parallel, and the distance between them becomes a predetermined gap G.

After such a bonding process is completed, as shown by a two-dot chain line in FIG. 7C, the door 26d is opened by the operation of the opening / closing drive unit 27b to open the entrance / exit of the chamber 26c, and the lower holding plate The holding of the plate-like work 1 is released by the operation of the holding means 22, and the plate- like works 1 and 2 that have been bonded together are carried out from the inside of the chamber 26 c by the work transfer means 24.
Thereafter, the above-described operation is repeated.

Accordingly, the second embodiment shown in FIGS. 7A to 7C provides the same effects as those of the first embodiment described above. In addition, as shown in the illustrated example, only the lower plate-like workpiece 2 is used as the main agent. When the liquid 3a and the auxiliary agent liquid 3b are alternately dispersed and arranged, it is not necessary to turn the plate-like workpiece 2 upside down or tilt from the application step of the main agent solution 3a and the auxiliary agent solution 3b to the bonding step. Therefore, there is an advantage that the main agent liquid 3a and the auxiliary agent liquid 3b applied thereto can be prevented from dripping, and the main agent liquid 3a and the auxiliary agent liquid 3b can be prevented from being mixed before being bonded by the liquid dripping.

In the embodiment of the present invention, as an example of application of the main agent liquid 3a and the auxiliary agent liquid 3b, an example in which both the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2 are disposed so as to face each other, Although an example in which the workpieces 1 and 2 are alternately dispersed and arranged on only one of the opposing surfaces 1a and 2a is shown, the present invention is not limited to this, and these two coating examples are opposed to a pair of plate- like workpieces 1 and 2. You may arrange | position in the surface 1a, 2a combining.
In the illustrated example, the main agent liquid 3a and the auxiliary agent liquid 3b are all applied to the opposing surfaces 1a and 2a of the plate- like workpieces 1 and 2 so as to have the same size, but the present invention is not limited thereto, and the main agent liquid 3a is not limited thereto. Depending on the appropriate mixing ratio of the secondary agent liquid 3b, different sizes may be applied.
