Description

顯示裝置用構件的製造裝置及顯示裝置用構件的製造方法 Manufacturing device for display device member and manufacturing of display device member Making method

本發明是有關於一種顯示裝置用構件的製造裝置及顯示裝置用構件的製造方法。 The present invention relates to a device for manufacturing a member for a display device and a method for manufacturing a member for a display device.

一般而言，以液晶顯示器或有機電致發光(electroluminescence，EL)顯示器為代表的平板狀的顯示裝置(平板顯示器)，是將顯示面板，視需要而將操作用的觸控面板或保護表面的保護面板(蓋面板)、背光源或其導光板等組裝至平板顯示器的框體而構成。 Generally speaking, a flat-panel display device (flat panel display) represented by a liquid crystal display or an organic electroluminescence (EL) display is a display panel, and a touch panel for operation or a protective surface is used as needed. A protective panel (cover panel), a backlight, or a light guide plate thereof are assembled into a housing of a flat panel display.

該些顯示面板、觸控面板、蓋面板、背光源或其導光板等工件(以下簡稱作工件)被積層而組裝至平板顯示器的框體。各個工件以個別或者預先積層的狀態而組裝。例如，亦使用在保護蓋上積層觸控面板而構成為複合面板者。 These display panels, touch panels, cover panels, backlights, or light guide plates thereof (hereinafter referred to as workpieces) are laminated and assembled to the frame of the flat panel display. Each workpiece is assembled individually or in a laminated state. For example, a touch panel is laminated on a protective cover to form a composite panel.

而且，就顯示面板而言，亦使用組裝觸控面板的功能者。如此，雖工件具有各種形態，但以下將構成顯示裝置的工件積層多個所得者稱作顯示裝置用構件。 Moreover, as for the display panel, a function of assembling a touch panel is also used. As described above, although the workpiece has various forms, a laminate of a plurality of workpieces constituting a display device is hereinafter referred to as a member for a display device.

若在此種作為顯示裝置用構件而積層的各工件之間設置間隙，則因外光反射而使顯示器的顯示面的視認性降低。為了應對該情況，藉由將各工件經由黏著層而貼合並積層，從而填埋各工件之間的間隙。 If a gap is provided between the workpieces laminated as such a member for a display device, the visibility of the display surface of the display is reduced due to reflection of external light. In order to cope with this situation, the gaps between the workpieces are filled by bonding and stacking the respective workpieces through an adhesive layer.

所述工件的積層中，有使用黏著片而貼合的方法及使用具有流動性的液狀黏著劑而貼合的方法。黏著片的價格比黏著劑高，且需要剝離紙的剝離等步驟。因此，根據近年來的成本削減的要求等，使用黏著劑的貼合正在增加。 The multilayer of the workpiece includes a method of bonding using an adhesive sheet and a method of bonding using a liquid adhesive having fluidity. Adhesive sheets are more expensive than adhesives and require steps such as peeling of release paper. Therefore, in accordance with the demand for cost reduction in recent years, the number of laminations using an adhesive is increasing.

而且，所述黏著層有時會作為各工件之間的緩衝材而要求具有保護工件的功能。進而，因顯示器的大型化等，工件亦為大面積，從而容易產生變形。因此，為了吸收變形而保護工件，而存在對黏著層所要求的厚度增加的傾向。例如，要求數百微米(μm)的厚度。 In addition, the adhesive layer may be required to have a function of protecting the workpiece as a buffer material between the workpieces. Furthermore, due to the enlargement of the display, etc., the workpiece also has a large area, which easily deforms. Therefore, in order to protect the workpiece to absorb the deformation, the thickness required for the adhesive layer tends to increase. For example, a thickness of several hundred micrometers (μm) is required.

若欲使用液狀黏著劑來確保所述黏著層的厚度，則必要的黏著劑的量會增加。於是，塗佈於工件的黏著劑流動，而容易自工件擠出。因此，在工件的表面塗佈黏著劑，並且以塗佈形狀不會變形的方式進行暫時硬化(參照專利文獻1)。 If a liquid adhesive is to be used to ensure the thickness of the adhesive layer, the amount of necessary adhesive will increase. As a result, the adhesive applied to the workpiece flows and is easily squeezed out of the workpiece. Therefore, an adhesive is applied to the surface of the workpiece, and temporarily hardened so that the applied shape does not deform (see Patent Document 1).

例如，一邊自狹縫型噴嘴將UV硬化樹脂的黏著劑塗佈於工件的塗佈面，一邊使噴嘴與工件相對移動，藉此對工件的整個塗佈面塗佈黏著劑，從而形成矩形形狀的黏著層。此時，追隨噴嘴的正後方附近，藉由照射部照射UV光，藉此使黏著劑暫時硬化而抑制流動。 For example, while applying a UV-curable resin adhesive to a coating surface of a workpiece from a slit nozzle, the nozzle and the workpiece are moved relatively to apply the adhesive to the entire coating surface of the workpiece to form a rectangular shape. Adhesive layer. At this time, following the vicinity of the nozzle, the UV light is irradiated by the irradiating part to temporarily harden the adhesive to suppress the flow.

例如，當將圖16(A)及圖16(B)所示的矩形的液晶面板S1，與圖16(C)及圖16(D)所示的外周形成著印刷框P的蓋面板S2進行貼合而構成顯示裝置用構件時，作為一例，黏著劑塗佈於液晶面板S1一側。一般而言，液晶面板S1的顯示區域與由蓋面板S2的印刷框P所包圍的內框F為相似的形狀且為大致相同的大小。因此，所謂對工件的整個表面塗佈黏著劑，是指使得形成於液晶面板S1的黏著層R1與由蓋面板S2的印刷框P所包圍的內框F為相似的形狀及大致相同的大小。即，在內框F為矩形的情況下，黏著層R1亦形成為大致相同大小的矩形。藉此，在將兩面板貼合時，黏著層R1的外緣與蓋面板的內框的框線重疊而無法看見黏著層R1的線，從而製品的外觀變得良好。 For example, when the rectangular liquid crystal panel S1 shown in FIGS. 16 (A) and 16 (B) is combined with the cover panel S2 with the printing frame P formed on the outer periphery shown in FIGS. 16 (C) and 16 (D), When the members for display device are bonded together, as an example, an adhesive is applied to the liquid crystal panel S1 side. In general, the display area of the liquid crystal panel S1 and the inner frame F surrounded by the printing frame P of the cover panel S2 have a similar shape and are approximately the same size. Therefore, the application of the adhesive to the entire surface of the workpiece means that the adhesive layer R1 formed on the liquid crystal panel S1 and the inner frame F surrounded by the printing frame P of the cover panel S2 have similar shapes and approximately the same size. That is, when the inner frame F is rectangular, the adhesive layer R1 is also formed into a rectangle having approximately the same size. Thereby, when the two panels are bonded, the outer edge of the adhesive layer R1 overlaps the frame line of the inner frame of the cover panel and the lines of the adhesive layer R1 cannot be seen, so that the appearance of the product becomes good.

如所述般，由使用狹縫型噴嘴的狹縫塗佈機來塗佈黏著劑，進而在塗佈後進行暫時硬化而抑制黏著劑的流動，藉此，可對黏著層的形狀及大小進行控制。然而，自噴嘴噴出的黏著劑在被塗佈於工件之後，因表面張力而成為半球形。因此，即便利用狹縫型噴嘴將黏著劑塗佈成矩形形狀，如圖16(B)所示，黏著層的緣部在剖面觀察時亦未成為直角，而成為上部帶有R的曲面狀態。而且，如圖16(A)所示，自上表面觀察時，四個角落的角的部分為帶有R的曲面狀態。即，因四個角落的部分中表面張力發揮大的作用，故成為1/4的球形狀，從而成為R形成得比其他部分大的狀態。 As described above, a slit coater using a slit nozzle is used to apply the adhesive, and then it is temporarily hardened after application to suppress the flow of the adhesive, whereby the shape and size of the adhesive layer can be adjusted. control. However, after the adhesive sprayed from the nozzle is applied to the workpiece, it becomes hemispherical due to surface tension. Therefore, even if the adhesive is applied in a rectangular shape using a slit nozzle, as shown in FIG. 16 (B), the edge portion of the adhesive layer does not become a right angle when viewed in cross section, but becomes a curved surface with an R at the upper portion. status. Moreover, as shown in FIG. 16 (A), when viewed from the upper surface, the corner portions of the four corners are in a curved state with R. That is, since the surface tension exerts a large effect in the four corner portions, it has a 1/4 spherical shape, and R is formed to be larger than the other portions.

若在該狀態下將液晶面板S1與蓋面板S2貼合，則如圖17(A)、圖17(B)所示，存在於黏著層R1的緣部與蓋面板S2的內框F的框線之間產生間隙的可能性。亦可預先考慮形成於緣部的R的大小來控制塗佈形狀，但關於緣部的四個角落的部分，因形成的R比直線部分大，故有時會在與內框F的四個角落之間形成能夠看到的程度的間隙。 When the liquid crystal panel S1 and the cover panel S2 are bonded in this state, as shown in FIGS. 17 (A) and 17 (B), the edge portion of the adhesive layer R1 and the frame of the inner frame F of the cover panel S2 are present. The possibility of gaps between lines. It is also possible to control the coating shape in advance by considering the size of R formed on the edge portion. However, since the R formed on the four corner portions of the edge portion is larger than the straight portion, it may sometimes be four A gap is formed between the corners so that it can be seen.

近年來，要求顯示面板的顯示區域的擴大化，從而要求印刷框的寬度儘可能窄。當有所述嚴格要求時，即便間隙形成得小，亦存在就外觀而言造成製品不良的可能性。而且，在將顯示面板與觸控面板等貼合時，若與印刷框無關，而在貼合的面的緣部存在未填充黏著劑的部分，則黏著層緣部的線會存在於顯示區域中，從而造成外觀上的不良。無論如何，容易自間隙部分產生剝離等，從而影響製品壽命。 In recent years, enlargement of the display area of a display panel is required, and the width of a print frame is required to be as narrow as possible. When there are such strict requirements, even if the gap is formed small, there is a possibility that the product may be defective in terms of appearance. In addition, when the display panel is bonded to a touch panel or the like, if there is no portion filled with an adhesive at the edge portion of the surface to be bonded regardless of the print frame, the line of the edge portion of the adhesive layer will exist in the display area. Medium, resulting in poor appearance. In any case, peeling and the like are likely to occur from the gap portion, thereby affecting product life.

本發明的目的為了解決所述課題，而提供一種顯示裝置用構件的製造裝置及製造方法，該顯示裝置用構件的製造裝置利用補充用黏著劑來填充黏著層的緣部與工件之間產生的間隙，藉此可製造高品質的顯示裝置用構件，且製品的良率亦可提高。 In order to solve the problems, an object of the present invention is to provide a manufacturing apparatus and a manufacturing method for a member for a display device. The manufacturing device for a member for a display device fills a gap between an edge of an adhesive layer and a workpiece with a supplementary adhesive. The gap can be used to manufacture a high-quality display device member, and the yield of the product can be improved.

[第1實施形態] [First Embodiment]

參照圖式，對本發明的實施形態(以下稱作實施形態)進行具體說明。 An embodiment (hereinafter referred to as an embodiment) of the present invention will be specifically described with reference to the drawings.

[構成] [Composition]

首先，參照圖1~圖6對本實施形態的構成進行說明。 First, the configuration of this embodiment will be described with reference to FIGS. 1 to 6.

[工件] [Artifact]

本裝置為製造成為顯示裝置用構件的積層體的顯示裝置用構件的製造裝置。顯示裝置用構件中，包含如將顯示面板與蓋面板加以積層而成的構件般的具備顯示功能的構件，亦包含如將蓋面板與觸控面板加以積層而成的構件般僅該構件中不具備顯示功能的構件。即，成為積層對象的工件有顯示面板、觸控面板、蓋面板、背光源或其導光板等各種工件，本實施形態中，對如下示例進行說明，即，將顯示面板與蓋面板經由黏著劑而貼合，藉此構成顯示裝置用構件。 This device is a manufacturing device for a member for a display device that manufactures a laminated body that is a member for a display device. The components for a display device include a component having a display function such as a component obtained by laminating a display panel and a cover panel, and also include a component obtained by laminating a cover panel and a touch panel. Components with display functions. That is, the workpieces to be laminated include various workpieces such as a display panel, a touch panel, a cover panel, a backlight, or a light guide plate thereof. In this embodiment, an example will be described in which the display panel and the cover panel are passed through an adhesive. By bonding, a member for a display device is configured.

顯示面板有液晶面板或有機EL面板等各種面板，其亦有各種形狀，但此處，作為一例而說明如圖16(A)中所示般使用矩形形狀液晶面板S1的示例。黏著劑可塗佈於液晶面板S1與蓋面板S2中的任一者上，或者亦可塗佈於兩者上。本實施形態中，如圖16(B)所示，對如下示例進行說明，即，將黏著劑以規定的厚度塗佈於液晶面板S1的表面，而形成黏著層R1。黏著劑以遍布液晶面板S1的整個面的方式塗佈，但為了防止在貼合時黏著劑不會自兩面板之間擠出，而以稍微保留液晶面板S1的外緣的方式進行塗佈。即，黏著層R1為與液晶面板S1相似的矩形形狀，且為比液晶面板S1稍小的大小。 The display panel includes various panels such as a liquid crystal panel and an organic EL panel, and also has various shapes. Here, as an example, an example using a rectangular liquid crystal panel S1 as shown in FIG. 16 (A) will be described. The adhesive may be applied to any one of the liquid crystal panel S1 and the cover panel S2, or may be applied to both. In this embodiment, as shown in FIG. 16 (B), an example will be described in which an adhesive is applied to the surface of the liquid crystal panel S1 with a predetermined thickness to form an adhesive layer R1. The adhesive is applied so as to cover the entire surface of the liquid crystal panel S1. However, in order to prevent the adhesive from being squeezed between the two panels during bonding, the adhesive is applied so as to slightly retain the outer edge of the liquid crystal panel S1. That is, the adhesive layer R1 has a rectangular shape similar to the liquid crystal panel S1, and is slightly smaller than the liquid crystal panel S1.

蓋面板亦具有各種種類或形狀，本實施形態中，如圖16(C)及圖16(D)所示，使用比液晶面板S1大的矩形形狀的蓋面板S2。在該蓋面板S2的底面側，以對外緣進行飾邊的方式形成著規定寬度的印刷框P。即，自下表面觀察，於蓋面板S2上形成著由印刷框P包圍的內框F。圖16(C)及圖16(D)的例中，內框F為矩形形狀且四個角落被倒角，但不限於圖示的示例，亦可為五邊形或六邊形等其他多邊形狀，且俯視時四個角落亦可為直角。另外，如圖16(D)所示，內框F的四個角落於剖面觀察時為大致直角。內框F的大小比液晶面板S1稍小。所述黏著層R1以與該內框F為相似的形狀及大致相同的大小的方式塗佈。 The cover panel also has various types or shapes. In this embodiment, as shown in FIGS. 16 (C) and 16 (D), a rectangular cover panel S2 larger than the liquid crystal panel S1 is used. On the bottom surface side of the cover panel S2, the outer edge is shaped. A printing frame P having a predetermined width is formed. That is, when viewed from the lower surface, an inner frame F surrounded by a print frame P is formed on the cover panel S2. In the example of FIGS. 16 (C) and 16 (D), the inner frame F has a rectangular shape and the four corners are chamfered, but it is not limited to the example shown in the figure, and may be other polygons such as a pentagon or a hexagon. Shape, and the four corners can also be right-angled when viewed from above. In addition, as shown in FIG. 16 (D), the four corners of the inner frame F are substantially right angles when viewed in cross section. The size of the inner frame F is slightly smaller than that of the liquid crystal panel S1. The adhesive layer R1 is coated with a shape similar to the inner frame F and a size substantially the same.

藉由將液晶面板S1的塗佈著黏著劑的面及蓋面板S2的形成著印刷框P的面加以貼合，而構成顯示裝置用構件。於貼合時，塗佈於液晶面板S1的黏著劑的外緣以與蓋面板S2的內框F的線重疊的方式積層。液晶面板S1比蓋面板S2的內框F稍大，因而液晶面板S1的外緣積層於印刷框P上。由此，當自上方觀察所形成的積層體時，液晶面板S1的外緣被隱藏在印刷框P中而無法看見，從而可獲得良好的外觀。 The adhesive-coated surface of the liquid crystal panel S1 and the surface of the cover panel S2 on which the print frame P is formed are bonded to form a member for a display device. At the time of bonding, the outer edge of the adhesive applied to the liquid crystal panel S1 is laminated so as to overlap the line of the inner frame F of the cover panel S2. The liquid crystal panel S1 is slightly larger than the inner frame F of the cover panel S2. Therefore, the outer edge of the liquid crystal panel S1 is laminated on the printing frame P. Therefore, when the formed multilayer body is viewed from above, the outer edge of the liquid crystal panel S1 is hidden in the printing frame P and cannot be seen, so that a good appearance can be obtained.

The display device member L is manufactured through the steps in each device, and is carried out from the display device member manufacturing device 100 by the unloader 300. The structure and function of each device will be described in detail below.

[黏著劑塗佈裝置1] [Adhesive coating device 1]

黏著劑塗佈裝置1作為顯示裝置用構件的製造裝置100的塗佈部，將黏著劑R塗佈於工件的表面，而形成黏著層R1。本實施形態中，對如所述般在液晶面板S1的表面塗佈黏著劑R的示例進行說明，但亦可於蓋面板S2進行塗佈，或者於兩面板進行塗佈。 The adhesive coating device 1 is a coating part of the manufacturing apparatus 100 for a member for a display device, and applies an adhesive R to the surface of a workpiece to form an adhesive layer R1. In this embodiment, an example in which the adhesive R is applied to the surface of the liquid crystal panel S1 as described above is described. However, it may be applied to the cover panel S2 or to both panels.

如圖2(A)所示，黏著劑塗佈裝置1包括將液晶面板S1能夠沿水平方向往復移動地加以支持的支持單元11，以及分別配置於支持單元11的上方的塗佈單元12及照射單元13。 As shown in FIG. 2 (A), the adhesive coating device 1 includes a support unit 11 that supports the liquid crystal panel S1 in a horizontally reciprocating manner, a coating unit 12 and an irradiation unit that are respectively disposed above the support unit 11. Unit 13.

支持單元11將黏著劑塗佈裝置1中的液晶面板S1使塗佈面向上而加以支持。該支持單元11具有平台11a、及驅動機構11b。平台11a為載置著液晶面板S1的平板狀的工作台。驅動機構11b為使平台11a沿水平方向往復移動的機構。作為驅動機構11b，例如考慮設為藉由驅動源而旋轉的滾珠螺桿。然而，只要為使所載置的液晶面板S1能夠沿水平方向往復移動的裝置，則可為任一裝置。驅動機構11b中的平台11a的移動的開始、停止及速度藉由控制裝置7而控制。 The support unit 11 supports the liquid crystal panel S1 in the adhesive application device 1 with the application side facing upward. This support unit 11 includes a platform 11a and a driving mechanism 11b. The stage 11a is a flat-shaped table on which the liquid crystal panel S1 is placed. The driving mechanism 11b is a mechanism that reciprocates the platform 11a in the horizontal direction. As the drive mechanism 11b, for example, a ball screw that is rotated by a drive source is considered. However, any device may be used as long as it is a device that enables the placed liquid crystal panel S1 to reciprocate in the horizontal direction. The start, stop and speed of the movement of the platform 11a in the drive mechanism 11b are controlled by the control device 7.

塗佈單元12對液晶面板S1塗佈黏著劑R。塗佈單元12 包括收容黏著劑R的貯槽T及分注器14。貯槽T經由作為黏著劑R的流路的配管及對黏著劑R的供給量進行調節的閥而連接於分注器14。分注器14例如可使用具備狹縫的狹縫塗佈機，該狹縫塗佈機藉由泵而將黏著劑R以面狀供給至液晶面板S1。 The coating unit 12 applies an adhesive R to the liquid crystal panel S1. Coating unit 12 The storage tank T and the dispenser 14 containing the adhesive R are included. The storage tank T is connected to the dispenser 14 via a pipe that is a flow path of the adhesive R and a valve that adjusts the supply amount of the adhesive R. For the dispenser 14, for example, a slit coater having a slit can be used. The slit coater supplies the adhesive R to the liquid crystal panel S1 in a planar shape by a pump.

狹縫為與液晶面板S1的塗佈面平行且沿與液晶面板S1的相對移動的方向正交的方向細長地延伸的開口，該長度方向的長度與液晶面板S1的寬度同等或稍短。分注器14的前端部分形成噴嘴(狹縫噴嘴)，所述噴嘴在與載置於平台11a上的液晶面板S1相向的位置具備所述狹縫。 The slit is an opening parallel to the coating surface of the liquid crystal panel S1 and extending slenderly in a direction orthogonal to the direction of the relative movement of the liquid crystal panel S1, and the length in the longitudinal direction is equal to or slightly shorter than the width of the liquid crystal panel S1. The tip of the dispenser 14 forms a nozzle (slit nozzle), which is provided with the slit at a position facing the liquid crystal panel S1 placed on the stage 11a.

一邊自該噴嘴噴出黏著劑，一邊使載置著液晶面板S1的平台11a在噴嘴的下方移動，藉此如圖2(B)所示，將黏著劑R以面狀塗佈於液晶面板S1的大致整個面，從而形成矩形形狀的黏著層R1。在大致整個面，是指稍微保留邊緣的部分。如所述般，蓋面板S2的內框F的大小比液晶面板S1稍小。因此，將黏著層R1以稍微保留液晶面板S1的邊緣的方式而塗佈，藉此可形成與內框F為相似形狀及大致相同大小的黏著層R1。 While spraying the adhesive from the nozzle, the stage 11a on which the liquid crystal panel S1 is placed is moved below the nozzle, thereby applying the adhesive R in a planar shape to the Approximately the entire surface, thereby forming a rectangular adhesive layer R1. In the whole surface, it means a part with slightly retained edges. As described above, the size of the inner frame F of the cover panel S2 is slightly smaller than that of the liquid crystal panel S1. Therefore, the adhesive layer R1 is coated so as to slightly retain the edge of the liquid crystal panel S1, so that the adhesive layer R1 having a similar shape and substantially the same size as the inner frame F can be formed.

所使用的黏著劑R為藉由來自外部的能量的照射而硬化的樹脂即可。例如考慮紫外線(UV)硬化樹脂或熱硬化樹脂，藉由其他電磁波、放射線等的能量而硬化的樹脂等。本實施形態中，使用UV硬化樹脂進行說明。所使用的黏著劑R的黏度未作特別限定。然而，關於非常需要抑制暫時硬化所致的流動的黏度，而設想2千cps~數萬cps，較佳為黏度相對低的2千cps~5千cps。 The adhesive R used may be a resin that is hardened by irradiation with external energy. For example, consider ultraviolet (UV) hardening resin or thermosetting resin, and resin hardened by other energy such as electromagnetic waves and radiation. In this embodiment, a description is given using a UV-curable resin. The viscosity of the adhesive R to be used is not particularly limited. However, regarding the viscosity of the flow due to temporary hardening, it is conceivable that 2 thousand cps to tens of thousands of cps, and preferably a relatively low viscosity of 2 thousand cps to 5 thousand cps.

照射單元13為對黏著劑R照射用以暫時硬化的能量的處理部。暫時硬化是指黏著劑R的大部分凝膠化但尚未完全硬化的狀態。關於照射的能量的種類，可根據所使用的黏著劑R的種類，而自紫外線、紅外線等的電磁波、放射線、熱源等中適當選擇。 The irradiation unit 13 is a processing unit that irradiates the adhesive R with energy for temporary hardening. The temporary hardening refers to a state in which most of the adhesive R is gelled but not yet completely hardened. The type of the energy to be irradiated can be appropriately selected from electromagnetic waves, radiation, heat sources, and the like, such as ultraviolet rays and infrared rays, according to the type of the adhesive R used.

本實施形態中，因黏著劑R使用的是UV硬化樹脂，故照射單元13具有可發出紫外線(UV)的1個或多個發光二極體(light-emitting diode，LED)或雷射二極體(Laser Diode，LD)、燈等照射源。照射單元13在平台11a上方，以與塗佈單元12鄰接的方式而配置，照射源以與載置於平台11a上的液晶面板S1相向的方式而安裝。藉此，可對伴隨平台11a的移動而塗佈著黏著劑R的液晶面板S1連續地進行能量照射。 In this embodiment, because the adhesive R is a UV-curable resin, the irradiation unit 13 has one or more light-emitting diodes (LEDs) or laser diodes that can emit ultraviolet rays (UV). Sources such as laser diode (LD), lamp, etc. The irradiation unit 13 is arranged above the stage 11 a so as to be adjacent to the coating unit 12, and the irradiation source is mounted so as to face the liquid crystal panel S1 placed on the stage 11 a. Accordingly, the liquid crystal panel S1 to which the adhesive R is applied in accordance with the movement of the stage 11 a can be continuously irradiated with energy.

另外，此處，對平台11a具備驅動機構，且平台11a朝向各單元移動的情況進行說明，但該移動只要為相對移動即可。即，亦可使平台11a固定，且塗佈單元12及照射單元13具備驅動機構，朝向平台11a而移動。 Here, a case where the platform 11a is provided with a driving mechanism and the platform 11a is moved toward each unit will be described, but the movement may be a relative movement. That is, the stage 11a may be fixed, and the application unit 12 and the irradiation unit 13 may be provided with a drive mechanism and move toward the stage 11a.

[貼合裝置2] [Laminating device 2]

貼合裝置2作為顯示裝置用構件的製造裝置100的貼合部，而將液晶面板S1與蓋面板S2積層並貼合。 The bonding device 2 is a bonding portion of the manufacturing device 100 for a member for a display device, and the liquid crystal panel S1 and the cover panel S2 are laminated and bonded together.

如圖3(A)所示，貼合裝置2成為在腔室21內使下側板22與上側板23相向配置的構成。腔室21可上下移動，若向上方移動則下側板22與上側板23向外部開放，從而可搬入液晶面板S1與蓋面板S2。若向下方移動，則下側板22與上側板23收容於腔室21內，從而在腔室21內部形成密閉空間。腔室21可利用未圖示的排氣部件來調整內部壓力。即，若搬入液晶面板S1與蓋面板S2，則腔室21下降而內部被密閉後減壓，且在減壓環境下進行貼合。 As shown in FIG. 3 (A), the bonding device 2 has a configuration in which the lower plate 22 and the upper plate 23 are arranged to face each other in the chamber 21. The chamber 21 can be moved up and down, and if it moves upward, the lower side plate 22 and the upper side plate 23 are opened to the outside, so that the liquid crystal surface can be carried in Board S1 and cover panel S2. When moving downward, the lower side plate 22 and the upper side plate 23 are accommodated in the chamber 21, and a closed space is formed inside the chamber 21. The internal pressure of the chamber 21 can be adjusted by an exhaust member (not shown). That is, when the liquid crystal panel S1 and the cover panel S2 are carried in, the chamber 21 is lowered, the interior is sealed, and the pressure is reduced, and bonding is performed in a reduced pressure environment.

本實施形態中，作為一例，對如下情況進行說明，即，於下側板22支持塗佈著黏著劑R的液晶面板S1，並於上側板23保持蓋面板S2。 In this embodiment, as an example, a description will be given of a case where the liquid crystal panel S1 coated with the adhesive R is supported on the lower plate 22 and the cover panel S2 is held on the upper plate 23.

作為上側板23的保持機構，例如可應用靜電夾盤、機械夾盤、真空夾盤、黏著夾盤等現在或將來能夠利用的所有保持機構。亦可併用多種夾盤。上側板23中具備驅動機構25。藉由該驅動機構25，上側板23能夠沿水平方向及上下方向移動。 As the holding mechanism of the upper plate 23, for example, all holding mechanisms that can be used now or in the future can be applied, such as an electrostatic chuck, a mechanical chuck, a vacuum chuck, and an adhesive chuck. Multiple chucks can also be used together. The upper plate 23 includes a drive mechanism 25. The driving mechanism 25 allows the upper plate 23 to move in the horizontal direction and the vertical direction.

藉由上側板沿水平方向移動，而進行液晶面板S1與蓋面板S2的位置對準。進而，如圖3(B)所示，上側板向下方向移動，將所保持的蓋面板S2擠壓並積層於支持於下側板22的液晶面板S1。液晶面板S1與蓋面板S2經由塗佈於液晶面板S1的表面的黏著劑R而貼合，從而形成著積層體S10。 By moving the upper side plate in the horizontal direction, the position alignment of the liquid crystal panel S1 and the cover panel S2 is performed. Further, as shown in FIG. 3 (B), the upper plate is moved downward, and the held cover plate S2 is pressed and laminated on the liquid crystal panel S1 supported by the lower plate 22. The liquid crystal panel S1 and the cover panel S2 are bonded together via an adhesive R applied to the surface of the liquid crystal panel S1 to form a laminated body S10.

另外，下側板22亦可具備與上側板23相同的保持機構，使得所支持的液晶面板S1的位置不會偏移。 In addition, the lower side plate 22 may be provided with the same holding mechanism as the upper side plate 23 so that the position of the supported liquid crystal panel S1 does not shift.

[硬化裝置3] [Hardening device 3]

硬化裝置3作為顯示裝置用構件的製造裝置100的硬化部，而使將液晶面板S1與蓋面板S2貼合的黏著層R1硬化。如圖4 (A)、圖4(B)所示，硬化裝置3包括載置著積層體S10的載置台31、及配置於載置台31上的照射單元33。 The hardening device 3 serves as a hardening portion of the manufacturing device 100 for a member for a display device, and hardens the adhesive layer R1 that bonds the liquid crystal panel S1 and the cover panel S2. Figure 4 As shown in FIGS. 4A and 4B, the curing device 3 includes a mounting table 31 on which the laminated body S10 is mounted, and an irradiation unit 33 disposed on the mounting table 31.

照射單元33包含照射硬化能量的裝置。關於所照射的能量的種類，可根據所使用的黏著劑R的種類，而自紫外線、紅外線等的電磁波、包含粒子束的放射線等中適當選擇。在使用UV硬化樹脂作為黏著劑R的情況下，照射單元33例如可包含能夠發出UV的1個或多個燈或LED等。照射單元33的照射可調節為能夠照射用以使黏著層R1硬化所需的量的能量。該能量的量根據照射的強度與時間來調整。例如，可照射使黏著劑塗佈裝置1中暫時硬化的黏著層R1完全硬化所需的紫外線，從而可調整照射的強度與時間。當然，不伴隨暫時硬化而使黏著層R1完全硬化的情況亦同樣。 The irradiation unit 33 includes a device that irradiates hardening energy. The type of energy to be irradiated can be appropriately selected from electromagnetic waves such as ultraviolet rays and infrared rays, radiation including particle beams, and the like according to the type of the adhesive R used. In the case where a UV-curable resin is used as the adhesive R, the irradiation unit 33 may include, for example, one or more lamps or LEDs capable of emitting UV. The irradiation of the irradiation unit 33 can be adjusted to be able to irradiate an amount of energy required to harden the adhesive layer R1. The amount of energy is adjusted according to the intensity and time of irradiation. For example, ultraviolet rays required to completely harden the temporarily hardened adhesive layer R1 in the adhesive coating device 1 can be irradiated, so that the intensity and time of irradiation can be adjusted. Of course, the same applies to the case where the adhesive layer R1 is completely cured without being temporarily cured.

[搬送裝置4] [Transfer device 4]

搬送裝置4構成顯示裝置用構件的製造裝置100的搬送部。搬送裝置4包含將液晶面板S1與蓋面板S2向所述黏著劑塗佈裝置1、貼合裝置2及硬化裝置3的各部搬送的搬送部及其驅動機構。作為搬送部，例如考慮轉台、輸送機、可在軌道上行走地設置的拾取部件等，但只要為可在所述各裝置之間搬送液晶面板S1與蓋面板S2者，則可為任一裝置。 The transfer device 4 constitutes a transfer unit of the manufacturing device 100 for a member for a display device. The transfer device 4 includes a transfer unit and a driving mechanism for transferring the liquid crystal panel S1 and the cover panel S2 to each of the adhesive coating device 1, the bonding device 2, and the curing device 3. As the transfer unit, for example, a turntable, a conveyor, and a picking member that can be installed on a track can be considered. However, as long as the liquid crystal panel S1 and the cover panel S2 can be transferred between the devices, any device can be used .

本實施形態中，如圖5所示，對使用輸送機40作為搬送部的示例進行說明。液晶面板S1及蓋面板S2載置於該輸送機40的面而進行搬送。黏著劑塗佈裝置1、貼合裝置2及硬化裝置3 沿著該輸送機40而配置，利用未圖示的拾取部件而能夠自輸送機40向各裝置搬入搬出面板。 In the present embodiment, as shown in FIG. 5, an example in which the conveyor 40 is used as the conveyance unit will be described. The liquid crystal panel S1 and the cover panel S2 are placed on the surface of the conveyor 40 and conveyed. Adhesive coating device 1, bonding device 2 and curing device 3 It is arranged along this conveyor 40, and a pick-up member (not shown) can be used to carry in and out panels from the conveyor 40 to each device.

此處，為了方便說明，將藉由輸送機40搬送兩面板的方向設為「搬送方向」，輸送機40上與搬送方向正交的方向設為「橫斷方向」。將輸送機40的搬送方向上的裝載器200側設為「上游側」，卸載器300側設為「下游側」。輸送機40的橫斷方向上的靠近黏著劑塗佈裝置1、貼合裝置2及硬化裝置3的一側設為「內側」，遠側設為「近前側」。 Here, for convenience of explanation, a direction in which the two panels are conveyed by the conveyor 40 is referred to as a “conveying direction”, and a direction orthogonal to the conveying direction on the conveyor 40 is referred to as a “transverse direction”. The loader 200 side in the conveyance direction of the conveyor 40 is set to the “upstream side”, and the unloader 300 side is set to the “downstream side”. The side in the transverse direction of the conveyor 40 near the adhesive application device 1, the bonding device 2, and the curing device 3 is set to "inside", and the far side is set to "near front side".

搬送裝置4上，拍攝部5及黏著劑補充部6以在橫斷方向上鄰接的方式而設置。拍攝部5及黏著劑補充部6配置於輸送機40上的黏著劑塗佈裝置1與貼合裝置2之間。如圖6所示，拍攝部5包括：配置於輸送機40上方的相機本體51a，以及自相機本體51a朝向輸送機40延伸的的透鏡鏡筒51b。 On the conveying device 4, the imaging section 5 and the adhesive replenishing section 6 are provided so as to be adjacent to each other in the transverse direction. The imaging unit 5 and the adhesive replenishing unit 6 are disposed between the adhesive application device 1 and the bonding device 2 on the conveyor 40. As shown in FIG. 6, the imaging unit 5 includes a camera body 51 a disposed above the conveyor 40 and a lens barrel 51 b extending from the camera body 51 a toward the conveyor 40.

黏著劑補充部6配置於拍攝部5的裝置近前側，且包括收容補充用黏著劑R10的貯槽T10、及分注器61。貯槽T10經由作為黏著劑R的流路的配管及對供給量進行調節的閥而連接於分注器61。 The adhesive replenishing section 6 is disposed on the near side of the device of the imaging section 5 and includes a storage tank T10 containing a replenishing adhesive R10 and a dispenser 61. The storage tank T10 is connected to the dispenser 61 via a pipe that is a flow path of the adhesive R and a valve that adjusts the supply amount.

作為分注器61，可使用各種噴嘴，但理想的是能夠將少量的黏著劑正確地噴出至所需的部位者，例如，可包含射流噴嘴(jet nozzle)或針形噴嘴(needle nozzle)。分注器61經由固定件而安裝於拍攝部5的透鏡鏡筒51b，且將噴嘴前端以與輸送機40的上表面相向的方式配置。 As the dispenser 61, various nozzles can be used, but ideally, a small amount of adhesive can be accurately ejected to a desired portion, and for example, a jet nozzle or a needle nozzle can be included. The dispenser 61 is attached to the lens barrel 51 b of the imaging unit 5 via a fixture, and the tip of the nozzle is arranged to face the upper surface of the conveyor 40.

拍攝部5連結於未圖示的驅動機構。藉由該驅動機構，拍攝部5可至少向橫斷方向移動。連結於拍攝部5的黏著劑補充部6亦與拍攝部5一體地移動。另外，亦可不將拍攝部5與黏著劑補充部6連結，而各自設置驅動機構。 The imaging unit 5 is connected to a driving mechanism (not shown). With this drive mechanism, the imaging unit 5 can move at least in the transverse direction. The adhesive replenishing section 6 connected to the imaging section 5 also moves integrally with the imaging section 5. In addition, instead of connecting the imaging section 5 and the adhesive replenishing section 6, a driving mechanism may be provided.

藉由輸送機40的朝向搬送方向的移動與拍攝部5的朝向橫斷方向的移動的組合，而能夠對在輸送機40上搬送的液晶面板S1及蓋面板S2的所需部分進行拍攝。黏著劑補充部6亦同樣地，藉由輸送機40的朝向搬送方向的移動與黏著劑補充部6的朝向橫斷方向的移動的組合，而可對在輸送機40上搬送的液晶面板S1或蓋面板S2的所需部分供給補充用的黏著劑。關於拍攝部5與黏著劑補充部6的具體動作，將在作用項中進行詳述。 By combining the movement of the conveyor 40 in the conveying direction and the movement of the imaging unit 5 in the transverse direction, the required portions of the liquid crystal panel S1 and the cover panel S2 conveyed on the conveyor 40 can be captured. Similarly, the adhesive replenishing portion 6 can be combined with the liquid crystal panel S1 or the liquid crystal panel S1 conveyed on the conveyor 40 by a combination of the movement of the conveyor 40 in the conveying direction and the movement of the adhesive replenishing portion 6 in the transverse direction. A required portion of the cover panel S2 is supplied with a replenishing adhesive. The specific operations of the imaging section 5 and the adhesive replenishing section 6 will be described in detail in the action terms.

補充用黏著劑R10亦可使用與形成黏著層R1的黏著劑R相同者，亦可使用其他黏著劑。在使用其他黏著劑的情況下，例如，因不對補充用黏著劑R10進行暫時硬化，故理想的是使用黏度比黏著劑R高且流動少的黏著劑，例如宜使用具有與暫時硬化後的黏著劑R同等的黏度的黏著劑。 The replenishing adhesive R10 may be the same as the adhesive R forming the adhesive layer R1, and other adhesives may also be used. In the case of using other adhesives, for example, because the supplementary adhesive R10 is not temporarily hardened, it is desirable to use an adhesive with a higher viscosity than the adhesive R and less flow. For example, it is preferable to use an adhesive with temporary hardening. Agent R is an adhesive with the same viscosity.

[控制裝置7] [Control device 7]

控制裝置7為對顯示裝置用構件的製造裝置100的動作進行控制的裝置。控制裝置7進行構成各部的裝置的動作的控制、或液晶面板S1及蓋面板S2的搬送時序的控制、進而各裝置的動作所需的檢測處理或算出處理等。 The control device 7 is a device that controls the operation of the manufacturing device 100 for a member for a display device.

首先，如圖1所示，液晶面板S1及蓋面板S2藉由裝載器200而搬入至顯示裝置用構件的製造裝置100，且在搬送裝置4的輸送機40上搬送。各個面板以成為貼合面的面為上側的方式搬送。即，本實施形態中，液晶面板S1以形成著黏著層R1的面朝向上側的方式載置，蓋面板S2以形成著印刷框P的面朝向上側的方式載置於輸送機40。 First, as shown in FIG. 1, the liquid crystal panel S1 and the cover panel S2 are carried into a manufacturing apparatus 100 for a display device member by a loader 200, and are carried on a conveyor 40 of a carrying apparatus 4. Each panel is conveyed so that the surface which becomes a bonding surface becomes an upper side. That is, in this embodiment, the liquid crystal panel S1 is placed so that the surface on which the adhesive layer R1 is formed faces upward, and the cover panel S2 is placed on the conveyor 40 so that the surface on which the print frame P is formed faces upward.

[黏著劑塗佈處理] [Adhesive coating process]

如圖7(A)所示，液晶面板S1藉由未圖示的拾取部件而拾取，且載置於黏著劑塗佈裝置1的平台11a上。平台11a藉由驅動機構，而開始沿朝向塗佈單元12及照射單元13的方向(以後稱作「移動方向」)移動。 As shown in FIG. 7 (A), the liquid crystal panel S1 is picked up by a pickup member (not shown). Take it and place it on the platform 11a of the adhesive coating apparatus 1. The stage 11 a starts to move in a direction (hereinafter referred to as a “moving direction”) toward the coating unit 12 and the irradiation unit 13 by the driving mechanism.

如圖7(B)所示，塗佈單元12在液晶面板S1的塗佈開始的位置來到分注器14的狹縫噴嘴的前端位置之後，開始噴出黏著劑R。平台11a繼續移動，因而如圖7(C)所示，在液晶面板S1的面上塗佈著黏著劑R。當液晶面板S1的塗佈結束的位置來到狹縫噴嘴的前端位置之後，結束黏著劑R的噴出。塗佈開始的位置為液晶面板S1的一邊的端部(圖中為左端)，塗佈結束的位置為與其相向的一邊的端部(圖中為右端)。 As shown in FIG. 7 (B), after the application unit 12 reaches the front end position of the slit nozzle of the dispenser 14 at the application start position of the liquid crystal panel S1, the application unit 12 starts to eject the adhesive R. As the stage 11a continues to move, as shown in FIG. 7 (C), an adhesive R is applied to the surface of the liquid crystal panel S1. When the position where the application of the liquid crystal panel S1 is completed reaches the tip position of the slit nozzle, the ejection of the adhesive R is terminated. The position where the application is started is an end portion (the left end in the drawing) of one side of the liquid crystal panel S1, and the position where the application is completed is the end portion (the right end) of the side facing the liquid crystal panel S1.

藉由該平台11a的移動及塗佈單元12的黏著劑R的噴出而在液晶面板S1的上表面形成著矩形形狀的黏著層R1。黏著層R1形成為與貼合著液晶面板S1的蓋面板S2的內框F為相似的形狀及大致相同的大小。「相似的形狀及大致相同的大小」是指在將液晶面板S1及蓋面板S2貼合時，黏著層R1的外緣與內框F的外緣大致重疊的形狀及大小。進而於提及「相似的形狀及相同的大小」的情況下，亦並非僅表示大小完全一致，亦包含表示大致相同大小的「大致相同大小」。 A rectangular adhesive layer R1 is formed on the upper surface of the liquid crystal panel S1 by the movement of the platform 11 a and the ejection of the adhesive R by the application unit 12. The adhesive layer R1 is formed to have a similar shape and substantially the same size as the inner frame F of the cover panel S2 to which the liquid crystal panel S1 is bonded. "Similar shape and approximately the same size" means a shape and size where the outer edge of the adhesive layer R1 and the outer edge of the inner frame F substantially overlap when the liquid crystal panel S1 and the cover panel S2 are bonded together. Furthermore, when referring to "similar shapes and the same size", it does not only mean that the sizes are completely the same, but also includes "roughly the same size" that indicates approximately the same size.

然而，如圖16(A)及圖16(B)所示，表面張力發揮作用而黏著層R1的緣部成為曲面形狀。尤其在四個角落的部分，表面張力發揮大的作用，因而R增大而成為1/4的球形狀。1/4的球形狀是指無論為水平觀察時亦是剖面觀察時均為曲面形狀。另一方面，蓋面板S2的內框F的四個角落於剖面觀察時為大致直角。貼合中，塗佈於液晶面板S1的黏著層R1的外緣以與蓋面板S2的內框F的線重疊的方式，即以接觸的方式而積層。然而，於黏著層R1的四個角落賦予大的R。因此，黏著層R1的四個角落於貼合中未到達能夠與蓋面板S2接觸的位置。即，若黏著層R1在該狀態下與蓋面板S2貼合，則如圖17(A)及圖17(B)所示，成為在黏著層R1的緣部或四個角落與蓋面板S2的內框F的邊或四個角落之間產生間隙的狀態。 However, as shown in FIGS. 16 (A) and 16 (B), the surface tension acts and the edge portion of the adhesive layer R1 has a curved shape. Especially in the four corners, the surface tension exerts a large effect, so R increases to form a 1/4 spherical shape. A 1/4 spherical shape means a curved surface shape both in horizontal observation and cross-sectional observation. another On the one hand, the four corners of the inner frame F of the cover panel S2 are substantially right angles when viewed in cross section. During bonding, the outer edge of the adhesive layer R1 applied to the liquid crystal panel S1 is laminated so as to overlap the line of the inner frame F of the cover panel S2, that is, to be in contact with each other. However, large R is given to the four corners of the adhesive layer R1. Therefore, the four corners of the adhesive layer R1 did not reach the position where they can contact the cover panel S2 during bonding. That is, if the adhesive layer R1 is bonded to the cover panel S2 in this state, as shown in FIG. 17 (A) and FIG. 17 (B), it becomes the edge or four corners of the adhesive layer R1 and the cover panel S2. A gap occurs between the sides or four corners of the inner frame F.

平台11a進一步繼續移動，並如圖7(C)所示，於黏著層R1的始端位於照射單元13的下方後，照射單元13開始照射能量。平台11a繼續移動，而於黏著層R1的終端越過照射單元13之後，照射單元13結束照射。黏著層R1成為暫時硬化的狀態，而成為抑制黏著劑R的流動的狀態。此時，宜為對由照射單元13照射的總能量進行調整，而調整黏著劑R的硬化率。或者，宜為對由照射單元13照射能量的部分的環境氣體的成分進行調整，而調整黏著劑R的硬化率。該情況下，亦可設為覆蓋位於照射單元13的下方的黏著層R1的周圍而可進行內部的環境調整的機構。另外，暫時硬化處理並非為必需，亦可考慮黏著劑R的黏度等而適當省略。 The platform 11a continues to move further, and as shown in FIG. 7 (C), after the start end of the adhesive layer R1 is located below the irradiation unit 13, the irradiation unit 13 starts to irradiate energy. The platform 11a continues to move, and after the terminal of the adhesive layer R1 passes the irradiation unit 13, the irradiation unit 13 ends the irradiation. The adhesive layer R1 is temporarily hardened and is in a state where the flow of the adhesive R is suppressed. At this time, it is preferable to adjust the hardening rate of the adhesive R in order to adjust the total energy irradiated by the irradiation unit 13. Alternatively, it is preferable to adjust the hardening rate of the adhesive R in order to adjust the components of the ambient gas in the part irradiated with energy by the irradiation unit 13. In this case, it is also possible to set it as the mechanism which can cover the surroundings of the adhesive layer R1 located under the irradiation unit 13, and can perform internal environment adjustment. In addition, the temporary hardening treatment is not necessary, and may be appropriately omitted in consideration of the viscosity of the adhesive R and the like.

[拍攝處理、位置檢測處理及黏著劑補充處理] [Shooting process, position detection process, and adhesive replenishment process]

形成著黏著層R1的液晶面板S1藉由未圖示的拾取部件而自黏著劑塗佈裝置1搬出，並再次載置於搬送裝置4的輸送機40上，而與蓋面板S2合流。如圖5所示，液晶面板S1與蓋面板S2以在輸送機40的橫斷方向上鄰接，且大致平行地排列的方式載置。圖式中圖示了如下示例，即，液晶面板S1載置於輸送機40內側，蓋面板S2載置於輸送機40的近前側，但載置位置不限於此，亦可將液晶面板S1載置於輸送機40近前側，蓋面板S2載置於輸送機40內側。液晶面板S1與蓋面板S2在輸送機40上搬送，並移動至拍攝部5及黏著劑補充部6的下方為止。 The liquid crystal panel S1 on which the adhesive layer R1 is formed is carried out from the adhesive coating device 1 by a pick-up member (not shown), and placed on the conveyor 40 of the carrying device 4 again. And merge with the cover panel S2. As shown in FIG. 5, the liquid crystal panel S1 and the cover panel S2 are placed so as to be adjacent to each other in the transverse direction of the conveyor 40 and are arranged in parallel. The figure illustrates an example in which the liquid crystal panel S1 is placed on the inside of the conveyor 40 and the cover panel S2 is placed on the near side of the conveyor 40, but the placement position is not limited to this, and the liquid crystal panel S1 may be placed on It is placed on the front side of the conveyor 40, and the cover panel S2 is placed on the inside of the conveyor 40. The liquid crystal panel S1 and the cover panel S2 are conveyed on a conveyor 40 and moved below the imaging section 5 and the adhesive replenishing section 6.

此處，進行拍攝部5的拍攝處理、控制裝置7的位置檢測處理及黏著劑補充部6的黏著劑補充處理。 Here, the imaging processing by the imaging section 5, the position detection processing by the control device 7, and the adhesive replenishment processing by the adhesive replenishing section 6 are performed.

為了獲取後述的貼合處理的兩面板的位置對準中所使用的資料而進行拍攝處理及位置檢測處理。如所述般，液晶面板S1與蓋面板S2以形成於液晶面板S1的黏著層R1的外緣與蓋面板S2的內框F的線重疊的方式而積層。即，以將形成於液晶面板S1上的黏著層R1的四個角落與蓋面板S2的內框F的四個角落(以下亦簡稱作「蓋面板S2的四個角落」)對準的方式進行貼合。當在兩面板的四個角落的位置有偏移的情況下，需要在貼合前對該偏移進行修正。因此，拍攝處理中進行液晶面板S1及蓋面板S2的內框F的四個角落的拍攝，而在位置檢測處理中特定兩面板的四個角落的座標。 In order to acquire the data used for the positional alignment of the two panels of the bonding process described later, imaging processing and position detection processing are performed. As described above, the liquid crystal panel S1 and the cover panel S2 are laminated so that the outer edge of the adhesive layer R1 formed on the liquid crystal panel S1 and the line of the inner frame F of the cover panel S2 overlap. That is, the four corners of the adhesive layer R1 formed on the liquid crystal panel S1 are aligned with the four corners of the inner frame F of the cover panel S2 (hereinafter also referred to as "the four corners of the cover panel S2"). fit. When the positions of the four corners of the two panels are offset, the offset needs to be corrected before bonding. Therefore, the four corners of the inner frame F of the liquid crystal panel S1 and the cover panel S2 are photographed in the photographing process, and the coordinates of the four corners of the two panels are specified in the position detection process.

為了該貼合處理中的位置對準而獲取的液晶面板S1或蓋面板S2的內框F的四個角落的座標亦於黏著劑補充處理中被利用。這是因為黏著劑補充處理是針對任一面板的四個角落而進行。 The coordinates of the four corners of the inner frame F of the liquid crystal panel S1 or the cover panel S2 obtained for the alignment during the bonding process are also used in the adhesive replenishment process. This is because the adhesive replenishment process is performed on the four corners of any panel.

如所述般，因在形成於液晶面板S1的黏著層R1的四個角落形成R，故若直接與蓋面板S2貼合，則在與蓋面板S2的內框F的四個角落之間產生間隙。黏著劑補充部6為了利用補充用黏著劑R10來填充該間隙，而對黏著層R1的緣部的四個角落供給補充用黏著劑R10。在與蓋面板S2的內框F的四個角落之間間隙微小，而為了填充該微小間隙需要將少量的補充用黏著劑R10噴出至正確的位置。此處，藉由利用為了兩面板的位置對準而特定的角落的座標，而可對正確的位置噴出補充用黏著劑R10。 As described above, since R is formed at the four corners of the adhesive layer R1 formed on the liquid crystal panel S1, if it is directly bonded to the cover panel S2, it will occur between the four corners of the inner frame F of the cover panel S2. gap. In order to fill the gap with the replenishing adhesive R10, the adhesive replenishing section 6 supplies replenishing adhesive R10 to four corners of the edge portion of the adhesive layer R1. The gaps between the four corners of the inner frame F of the cover panel S2 are small, and in order to fill the small gaps, it is necessary to spray a small amount of the replenishing adhesive R10 to the correct position. Here, by using the coordinates of the corners specified for the alignment of the two panels, the replenishing adhesive R10 can be ejected to the correct position.

此處，所謂「對黏著層R1的緣部的四個角落供給補充用黏著劑R10」包含直接的供給及間接的供給。「直接地供給」是指將補充用黏著劑R10直接附著於形成著R的黏著層R1的緣部的四個角落。「間接地供給」是指在蓋面板S2上而非黏著層R1上附著補充用黏著劑R10。貼合處理中，蓋面板S2的內框F的四個角落定位並積層於液晶面板S1的黏著層R1的緣部的四個角落。因此，若對蓋面板S2的內框F的四個角落附著補充用黏著劑R10，則結果可對黏著層R1的緣部的四個角落供給補充用黏著劑R10。 Here, "supplying the replenishing adhesive R10 to the four corners of the edge of the adhesive layer R1" includes direct supply and indirect supply. "Direct supply" means that the replenishing adhesive R10 is directly attached to the four corners of the edge portion of the adhesive layer R1 on which R is formed. "Indirect supply" means that a supplementary adhesive R10 is attached to the cover panel S2 instead of the adhesive layer R1. In the bonding process, the four corners of the inner frame F of the cover panel S2 are positioned and laminated on the four corners of the edge portion of the adhesive layer R1 of the liquid crystal panel S1. Therefore, if the supplemental adhesive R10 is attached to the four corners of the inner frame F of the cover panel S2, as a result, the supplemental adhesive R10 can be supplied to the four corners of the edge portion of the adhesive layer R1.

拍攝處理、位置檢測處理及黏著劑補充處理可分別單獨地進行，亦可將輸送機40的朝向搬送方向的移動與拍攝部5及黏著劑補充部6的朝向橫斷方向的移動加以組合，而同時進行。 The imaging process, the position detection process, and the adhesive replenishment process may be performed separately, or the movement of the conveyor 40 in the conveying direction and the movement of the imaging unit 5 and the adhesive replenishing unit 6 in the transverse direction may be combined, Simultaneously.

例如，如圖8(A)所示，首先，使液晶面板S1及蓋面板S2朝向載置著它們的輸送機40的搬送方向移動，使位於面板的上游側的端部(以後稱作前端)停止於處於拍攝部5的下方的位置。接下來，如圖8(B)所示，使拍攝部5自裝置近前側向內側而沿橫斷方向移動，並於各角落的位置停止而獲取包含各角落的圖像。另外，輸送機40及拍攝部5的移動量及停止位置根據面板的尺寸等而預先規定，且可儲存於控制裝置7的記憶部。 For example, as shown in FIG. 8 (A), first, the liquid crystal panel S1 and the cover panel S2 are moved toward the conveyance direction of the conveyor 40 on which they are placed, so that they are positioned on the panel. An end portion (hereinafter referred to as a front end) on the upstream side of the camera stops at a position below the imaging portion 5. Next, as shown in FIG. 8 (B), the imaging unit 5 is moved from the near side of the device to the inside in the transverse direction, and stopped at the positions of the corners to acquire images including the corners. In addition, the moving amount and stopping position of the conveyor 40 and the imaging section 5 are predetermined in accordance with the size of the panel and the like, and can be stored in the memory section of the control device 7.

控制裝置7在拍攝部5每次獲取各角落的圖像時進行位置檢測處理。位置檢測可使用公知的方法。例如，關於液晶面板S1，對圖像進行解析而檢測面板的輪廓，將以面板兩邊的交點為中心的規定範圍特定為角落，並求出其座標。關於蓋面板S2，同樣地對圖像進行解析而對內框F的輪郭進行檢測，將以內框F的框線兩邊的交點為中心的規定範圍特定為角落，並求出其座標。 The control device 7 performs a position detection process every time the image capturing section 5 acquires an image of each corner. For the position detection, a known method can be used. For example, regarding the liquid crystal panel S1, an image is analyzed to detect the contour of the panel, and a predetermined range centered on the intersection between the two sides of the panel is specified as a corner, and its coordinates are obtained. Regarding the cover panel S2, the image is analyzed in the same manner, and the wheel of the inner frame F is detected, and a predetermined range centered on the intersection of both sides of the frame line of the inner frame F is specified as a corner, and its coordinates are obtained.

對進行補充用黏著劑R10的噴出的面板進行位置檢測處理後，亦根據由位置檢測處理獲取的座標而進行黏著劑補充處理。使黏著劑補充部6的分注器61移動至控制裝置7中特定的角落的座標。然後，自分注器61噴出補充用黏著劑R10。 After performing the position detection processing on the sprayed panel of the replenishing adhesive R10, the refilling processing is also performed according to the coordinates obtained by the position detection processing. The dispenser 61 of the adhesive replenishing section 6 is moved to the coordinates of a specific corner in the control device 7. Then, the refilling adhesive R10 is ejected from the dispenser 61.

在對蓋面板S2進行黏著劑補充處理的情況下，如圖9(A)所示，使分注器61移動至蓋面板S2的內框F的各角落的座標而噴出補充用黏著劑R10。如圖9(B)所示，補充用黏著劑R10以附靠在印刷框P的方式附著於蓋面板S2的內框F的角落。 When the cover panel S2 is replenished with an adhesive, as shown in FIG. 9 (A), the dispenser 61 is moved to the coordinates of each corner of the inner frame F of the cover panel S2, and the replenishing adhesive R10 is ejected. As shown in FIG. 9 (B), the replenishing adhesive R10 is attached to the corner of the inner frame F of the cover panel S2 so as to abut the printing frame P.

在對液晶面板S1進行黏著劑補充處理的情況下，如圖11(A)所示，使分注器61移動至液晶面板S1的各角落的座標，並噴出補充用黏著劑R10。如圖11(B)所示，補充用黏著劑R10 以觸碰到延伸至液晶面板S1的外緣間附近的黏著層R1的四個角落的方式附著。黏著層R1在黏著劑塗佈裝置1中被暫時硬化，因而補充用黏著劑R10不會被黏著層R1所吸收。 When the liquid crystal panel S1 is replenished with an adhesive, as shown in FIG. 11 (A), the dispenser 61 is moved to the coordinates of each corner of the liquid crystal panel S1, and the replenishing adhesive R10 is ejected. As shown in Figure 11 (B), R10 It adheres so that it may touch the four corners of the adhesive layer R1 extended to the vicinity of between the outer edges of the liquid crystal panel S1. The adhesive layer R1 is temporarily hardened in the adhesive coating device 1, and thus the supplementary adhesive R10 is not absorbed by the adhesive layer R1.

另外，分注器61連結於拍攝部5，且在橫斷方向上鄰接，因而在利用拍攝部5拍攝角落之後，使拍攝部5移動至裝置近前側或內側，藉此可使分注器61容易地移動至角落的座標。 In addition, the dispenser 61 is connected to the imaging unit 5 and is adjacent in the transverse direction. Therefore, after the corner is photographed by the imaging unit 5, the imaging unit 5 is moved to the front side or the inner side of the device, thereby enabling the dispenser 61 Easily move to corner coordinates.

當對前端側的各角落結束所述處理後，如圖8(A)所示，使輸送機40在搬送方向上移動，使位於液晶面板S1及蓋面板S2的下游側的端部(以後稱作後端)停止於處於拍攝部5的下方的位置。然後，如圖8(B)所示，一邊使拍攝部5自裝置內側向近前側在橫斷方向上移動一邊對後端側的各角落進行拍攝。與前端側同樣地，在每次獲取角落的圖像時由控制裝置7進行位置檢測處理，進而對進行補充用黏著劑R10的供給的面板進行黏著劑補充處理。 After the processing is completed for each corner on the front end side, as shown in FIG. 8 (A), the conveyor 40 is moved in the conveying direction so that the end portions (hereinafter referred to as downstream) of the liquid crystal panel S1 and the cover panel S2 (hereinafter referred to as It is stopped at a position below the imaging section 5. Then, as shown in FIG. 8 (B), each corner of the rear side is photographed while the imaging unit 5 is moved in the transverse direction from the inside of the device to the near side. As with the front end side, the position detection processing is performed by the control device 7 every time an image of a corner is acquired, and further, the panel is supplied with an adhesive replenishing process by supplying the replenishing adhesive R10.

另外，所述各角落的處理的順序為一例，順序可適當變更。而且，輸送機40的移動或拍攝部5及黏著劑補充部6的移動亦可為相對，例如亦可使拍攝部5及黏著劑補充部6在搬送方向或搬送方向的反方向上而非橫斷方向上移動並進行處理。 In addition, the order of processing in each corner is an example, and the order can be changed as appropriate. In addition, the movement of the conveyor 40 or the movement of the imaging section 5 and the adhesive replenishing section 6 may be relative. For example, the imaging section 5 and the adhesive replenishing section 6 may be moved in a direction opposite to the conveying direction instead of crossing. Move in the direction and process.

[貼合處理] [Laminating treatment]

當液晶面板S1及蓋面板S2的全部的四個角落的拍攝處理及位置檢測處理、與針對蓋面板S2的黏著劑補充處理結束時，液晶面板S1及蓋面板S2在輸送機40上搬送，且藉由未圖示的拾取部件搬入至貼合裝置2。此時，以維持所述位置檢測處理中檢測到的各角落的座標的方式進行搬入。 When the photographing processing and position detection processing of all four corners of the liquid crystal panel S1 and the cover panel S2 and the adhesive replenishment processing for the cover panel S2 are completed, the liquid crystal panel S1 and the cover panel S2 are conveyed on the conveyor 40, and With a pickup section (not shown) Pieces are carried into the laminating device 2. At this time, it is carried in so that the coordinates of each corner detected in the position detection process are maintained.

如圖3(A)所示，貼合裝置2中，形成著黏著層R1的液晶面板S1載置於下側板22。此時，以形成著黏著層R1的表面向上的方式載置。蓋面板S2以貼合的面向下的方式反轉，交付至上側板23並由保持機構保持。兩面板以保持搬送裝置4中檢測到的位置資訊的方式交付。 As shown in FIG. 3 (A), in the bonding device 2, the liquid crystal panel S1 on which the adhesive layer R1 is formed is placed on the lower side plate 22. At this time, it is mounted so that the surface on which the adhesive layer R1 is formed faces upward. The cover panel S2 is reversed with the attached surface facing downward, and is delivered to the upper side panel 23 and held by the holding mechanism. The two panels are delivered so as to hold the position information detected in the transport device 4.

此時，腔室21移動至上方，因而下側板22與上側板23開放。當兩面板的搬送結束時，腔室21以位於下方的方式被驅動，將下側板22與上側板23收容於腔室21的內部。腔室21內部形成著密閉空間，藉由未圖示的排氣部件而對密閉空間內進行減壓。 At this time, since the chamber 21 is moved upward, the lower side plate 22 and the upper side plate 23 are opened. When the conveyance of the two panels is completed, the chamber 21 is driven to be positioned downward, and the lower plate 22 and the upper plate 23 are housed inside the chamber 21. A closed space is formed inside the chamber 21, and the inside of the closed space is decompressed by an exhaust member (not shown).

液晶面板S1及蓋面板S2如所述般，以對準各自的四個角落的方式積層，但因亦有可能在各自的四個角落的位置產生偏移，故要在貼合前，進行液晶面板S1及蓋面板S2的位置修正。根據搬送裝置4的位置檢測處理中檢測到的各角落的座標來進行位置修正。位置修正可使用公知的方法，例如，可預先在控制裝置7的記憶部中儲存各角落的位置基準值，並根據該位置基準值與檢測到的各角落的座標的差分而算出位置修正量。 As described above, the liquid crystal panel S1 and the cover panel S2 are laminated so as to be aligned with the respective four corners. However, there may be deviations in the positions of the respective four corners. Therefore, it is necessary to perform liquid crystal before bonding. The positions of the panel S1 and the cover panel S2 are corrected. Position correction is performed based on the coordinates of each corner detected in the position detection process of the conveying device 4. A known method can be used for the position correction. For example, the position reference value of each corner can be stored in the memory of the control device 7 in advance, and the position correction amount can be calculated based on the difference between the position reference value and the coordinates of the detected corner.

根據所算出的位置修正量使上側板23在x方向、y方向、θ方向上移動，藉此對液晶面板S1及蓋面板S2的位置偏移進行修正。另外，此處對使上側板23移動來進行位置修正的示例進行了說明，但亦可使下側板22、或者上側板22及下側板23的雙方移動來進行位置修正。 The upper plate 23 is moved in the x direction, the y direction, and the θ direction based on the calculated position correction amount, thereby correcting the positional deviation of the liquid crystal panel S1 and the cover panel S2. In addition, the example in which the upper side plate 23 is moved to perform position correction is described here, but the lower side plate 22, or both of the upper side plate 22 and the lower side plate 23 may be used. The party moves to perform position correction.

在修正位置偏移之後，如圖3(B)所示，上側板23朝向下側板22下降，將保持於上側板23的蓋面板S2擠壓至支持於下側板22的液晶面板S1。形成於液晶面板S1表面的黏著層R1經由液晶面板S1而被按壓至下側板22，且密接於兩面板，藉此將兩面板貼合。 After correcting the positional deviation, as shown in FIG. 3 (B), the upper plate 23 is lowered toward the lower plate 22, and the cover panel S2 held by the upper plate 23 is pressed to the liquid crystal panel S1 supported by the lower plate 22. The adhesive layer R1 formed on the surface of the liquid crystal panel S1 is pressed to the lower side plate 22 through the liquid crystal panel S1 and is in close contact with the two panels, thereby bonding the two panels together.

所述黏著劑補充處理中，將對蓋面板S2進行黏著劑補充處理後的貼合表示於圖10(A)、圖10(B)中。若將兩面板貼合，則如圖10(A)所示，進行如下動作，即，附著於蓋面板S2的內框F的四個角落的補充用的黏著劑填埋間隙，該間隙產生於形成著R的黏著層R1的緣部的四個角落與剖面觀察為大致直角的蓋面板S2的內框F的四個角落之間。藉此，如圖10(B)所示，形成印刷框P與黏著層R1之間無間隙的積層體S10。另外，積層體S10中，補充用黏著劑R10因與黏著層R1一體化，故實際上補充用黏著劑R10與黏著層R1的交界消失。因此，圖10(B)中補充用黏著劑的符號R10由括號表示。 In the adhesive replenishing process, the bonding after the adhesive replenishing process is performed on the cover panel S2 is shown in FIGS. 10 (A) and 10 (B). When the two panels are bonded together, as shown in FIG. 10 (A), the following operation is performed, in which the gaps are filled with the adhesive for replenishment which is attached to the four corners of the inner frame F of the cover panel S2, and the gap is generated in Between the four corners of the edge portion of the adhesive layer R1 forming the R, and the four corners of the inner frame F of the cover panel S2 that are substantially right-angled in cross section. Thereby, as shown in FIG. 10 (B), a laminated body S10 is formed without a gap between the print frame P and the adhesive layer R1. In addition, in the multilayer body S10, since the supplementary adhesive R10 is integrated with the adhesive layer R1, the boundary between the supplementary adhesive R10 and the adhesive layer R1 actually disappears. Therefore, the symbol R10 for supplementary adhesive in FIG. 10 (B) is indicated by parentheses.

所述黏著劑補充處理中，將對液晶面板S1進行黏著劑補充處理後的貼合表示於圖12(A)、圖12(B)中。若將兩面板貼合，則如圖12(A)所示，進行如下動作，即，附著在形成於液晶面板S1上的黏著層R1的四個角落的補充黏著劑填埋間隙，該間隙產生於形成著R的黏著層R1的緣部的四個角落與剖面觀察為大致直角的蓋面板S2的內框F的四個角落之間。藉此，如圖 12(B)所示，形成印刷框P與黏著層R1之間無間隙的積層體S10。該積層體S10中，補充用黏著劑R10亦與黏著層R1一體化，因而圖12(B)中，亦與圖10(B)同樣地，補充用黏著劑的符號R10由括號表示。 In the adhesive replenishing process, the bonding after the adhesive replenishing process is performed on the liquid crystal panel S1 is shown in FIGS. 12 (A) and 12 (B). When the two panels are bonded, as shown in FIG. 12 (A), the following operations are performed. The supplementary adhesives adhered to the four corners of the adhesive layer R1 formed on the liquid crystal panel S1 fill the gaps, and the gaps are generated. Between the four corners of the edge portion of the adhesive layer R1 on which R is formed and the four corners of the inner frame F of the cover panel S2 which is substantially right-angled in cross section. With this, as shown As shown in FIG. 12 (B), a laminated body S10 having no gap between the printing frame P and the adhesive layer R1 is formed. In this laminated body S10, the supplementary adhesive R10 is also integrated with the adhesive layer R1. Therefore, in FIG. 12 (B), as in FIG. 10 (B), the symbol R10 for supplementary adhesive is indicated by brackets.

當液晶面板S1與蓋面板S2的貼合結束時，解除減壓狀態，腔室21向上方移動，而密閉空間開放。積層體S10自貼合裝置2搬出，並再次由搬送裝置4搬送。繼而，藉由未圖示的拾取部件而向硬化裝置3搬入。另外，在自貼合裝置2向硬化裝置3搬送的過程中，亦可將積層體S10在大氣中放置固定時間。該放置時間內，積層體S10藉由大氣壓而按壓且穩定。而且，即便黏著層R1中殘留孔隙，亦因放置充分時間，而減少孔隙。 When the bonding of the liquid crystal panel S1 and the cover panel S2 is completed, the decompressed state is released, the chamber 21 moves upward, and the closed space is opened. The laminated body S10 is carried out from the bonding device 2 and is carried again by the carrying device 4. Then, it is carried into the hardening device 3 by a picking member (not shown). In addition, the laminated body S10 may be left in the air for a fixed time during the process of being transferred from the bonding device 2 to the curing device 3. During this standing time, the laminated body S10 is pressed and stabilized by the atmospheric pressure. In addition, even if pores remain in the adhesive layer R1, the pores are reduced due to sufficient time for leaving them.

[硬化處理] [Hardening treatment]

硬化裝置3中，如圖4(A)、圖4(B)所示，積層體S10載置於載置台31，藉由照射單元33，而被照射使暫時硬化的黏著層R1完全硬化所需強度的紫外線，從而黏著層R1的正式硬化結束。 In the curing device 3, as shown in FIGS. 4 (A) and 4 (B), the laminated body S10 is placed on the mounting table 31, and is irradiated by the irradiation unit 33 to completely harden the temporarily hardened adhesive layer R1. The intensity of ultraviolet rays, and thus the formal hardening of the adhesive layer R1 is completed.

[效果] [effect]

(1)本實施形態的顯示裝置用構件的製造裝置100是將作為構成顯示裝置的一對工件的液晶面板S1及蓋面板S2經由黏著劑R而貼合，且包括：作為塗佈部的黏著劑塗佈裝置1，將黏著劑R以面狀塗佈於液晶面板S1上而形成黏著層R1；黏著劑補充部6，向液晶面板S1或蓋面板S2供給補充用黏著劑R10；以及作為貼合部的貼合裝置2，將液晶面板S1及蓋面板S2經由黏著層R1而貼合。補充用黏著劑R10對貼合裝置2中貼合的液晶面板S1及蓋面板S2，填充所述黏著層R1的緣部的至少一部分即四個角落與蓋面板S2之間產生的間隙。 (1) A manufacturing device 100 for a member for a display device according to this embodiment is a method for bonding a liquid crystal panel S1 and a cover panel S2 as a pair of workpieces constituting a display device via an adhesive R, and includes adhesion as a coating portion. The adhesive coating device 1 applies the adhesive R in a planar shape to the liquid crystal panel S1 to form an adhesive layer R1; the adhesive replenishing section 6 supplies the liquid crystal panel S1 or the cover panel S2 with a replenishing adhesive R10; The bonding device 2 of the bonding portion passes the liquid crystal panel S1 and the cover panel S2 through the adhesive layer R1. fit. The supplemental adhesive R10 is used to fill the gap between the liquid crystal panel S1 and the cover panel S2 in the bonding device 2 and at least a part of the edges of the adhesive layer R1, that is, the four corners, and the cover panel S2.

對利用表面張力的作用而成為曲面形狀的黏著層R1的四個角落、及相向的蓋面板S2之間所產生的間隙供給黏著劑而填充間隙，藉此預防因來自黏著層部分的剝離所致的破損，從而可製造外觀良好的顯示裝置用構件L，亦可提高製品的良率。另外，「填充間隙」並非是指填充貼合後最終所產生的間隙，而是指對若不供給補充用黏著劑R10便可能產生間隙的位置預先供給黏著劑，而防止最終產生間隙。 Supply the adhesive to fill the gaps between the four corners of the adhesive layer R1 that has a curved shape by the action of surface tension and the facing cover panel S2, thereby preventing the peeling from the adhesive layer portion. It is possible to manufacture a member L for a display device with a good appearance, and to improve the yield of a product. In addition, "filling the gap" does not refer to the gap that is finally generated after filling and bonding, but refers to pre-supplying an adhesive to a position where a gap may occur if the supplementary adhesive R10 is not supplied, so as to prevent the gap from finally being generated.

而且，藉由供給補充用黏著劑R10，在黏著劑塗佈裝置1中的黏著劑R的塗佈時，不再需要嚴格控制黏著層R1的緣部的形狀。藉此，可應用多種黏著劑或面板，而降低黏著劑的塗佈環境變動的影響，並可簡化維護或條件設置等。因此，顯示裝置用構件的製造裝置的應用範圍廣，而生產性亦可提高。 In addition, by supplying the replenishing adhesive R10, it is no longer necessary to strictly control the shape of the edge portion of the adhesive layer R1 when applying the adhesive R in the adhesive application device 1. Thereby, a variety of adhesives or panels can be applied, and the influence of changes in the coating environment of the adhesive can be reduced, and maintenance or condition setting can be simplified. Therefore, the application range of the manufacturing apparatus of the member for display apparatuses is wide, and productivity can be improved.

(2)黏著劑補充部6亦可對黏著層R1的四個角落直接供給補充用黏著劑R10。藉此，亦可根據黏著層R1的四個角落的曲面狀態的程度，對補充用黏著劑R10的位置或量進行微調。 (2) The adhesive replenishing section 6 may directly supply the replenishing adhesive R10 to the four corners of the adhesive layer R1. Accordingly, the position or amount of the replenishing adhesive R10 can also be fine-tuned according to the degree of the curved state of the four corners of the adhesive layer R1.

(3)亦可藉由黏著劑補充部6對與黏著層R1的四個角落對應的蓋面板的部分即內框F的四個角落供給補充用黏著劑R10，而對黏著層R1的四個角落間接地供給補充用黏著劑R10。即便未對成為曲面狀態的黏著層R1的四個角落直接補充黏著劑，只要對蓋面板S2的內框F的四個角落供給補充用黏著劑R10，在貼合裝置2的貼合中，結果亦對黏著層R1的四個角落補充黏著劑。因內框F的四個角落為平坦狀態，故容易進行控制以使補充用黏著劑R10向正確的位置噴出。 (3) The portion of the cover panel corresponding to the four corners of the adhesive layer R1, that is, the four corners of the inner frame F, can also be supplied with the adhesive R10 for replenishment by the adhesive replenishing portion 6, and four of the adhesive layer R1 The corner is supplied indirectly with supplemental adhesive R10. Even if the four corners of the adhesive layer R1 in a curved state are not directly supplemented with adhesive As long as the four corners of the inner frame F of the cover panel S2 are supplied with supplementary adhesives R10, the four corners of the adhesive layer R1 are also supplemented with the adhesive during the bonding of the bonding device 2. Since the four corners of the inner frame F are flat, it is easy to control so that the replenishing adhesive R10 is ejected to the correct position.

另外，在對黏著層R1直接供給補充用黏著劑R10的情況下，為了使補充用黏著劑R10不會被黏著層R1吸收，宜為在黏著劑塗佈裝置1中使黏著層R1暫時硬化，但在對蓋面板S2供給補充用黏著劑R10的情況下，因補充用黏著劑R10在貼合前不會被黏著層R1吸收，故亦可根據黏著劑的材質而省略暫時硬化。 In addition, when the supplementary adhesive R10 is directly supplied to the adhesive layer R1, in order to prevent the supplementary adhesive R10 from being absorbed by the adhesive layer R1, it is preferable to temporarily harden the adhesive layer R1 in the adhesive coating device 1, However, when the supplementary adhesive R10 is supplied to the cover panel S2, since the supplementary adhesive R10 is not absorbed by the adhesive layer R1 before bonding, the temporary hardening may be omitted according to the material of the adhesive.

(4)蓋面板S2上形成著矩形的內框F。黏著劑塗佈裝置1在液晶面板S1上形成與內框F為相似形狀及大致相同大小的黏著層R1。貼合裝置2中，以黏著層R1進入至內框F內的方式將液晶面板S1與蓋面板S2貼合。黏著劑補充部6對將液晶面板S1及蓋面板S2貼合而成的積層體S10，供給對黏著層R1的各角落與內框F的各角落之間最終產生的間隙進行填充的補充用黏著劑。 (4) A rectangular inner frame F is formed on the cover panel S2. The adhesive coating device 1 forms an adhesive layer R1 having a shape similar to that of the inner frame F and a substantially same size on the liquid crystal panel S1. In the bonding device 2, the liquid crystal panel S1 and the cover panel S2 are bonded so that the adhesive layer R1 enters the inner frame F. The adhesive replenishing section 6 supplies a supplementary adhesion to the laminated body S10 formed by bonding the liquid crystal panel S1 and the cover panel S2 to the gaps finally generated between each corner of the adhesive layer R1 and each corner of the inner frame F. Agent.

蓋面板S2的矩形的內框F的各角落為大致直角。尤其為了增大顯示區域，幾乎不存在設置於四個角落的R。另一方面，塗佈於矩形的黏著層R1的緣部的各角落塗佈後為曲面形狀。黏著層R1的緣部中，表面張力發揮大的作用的四個角落形成更大的曲面，間隙超過容許範圍的可能性亦大。因此，即便在黏著劑R的塗佈時或塗佈後不久黏著層R1的緣部能夠形成為容許範圍內的曲面，亦存在四個角落超出容許範圍的可能性。因此，藉由在黏著層R1的緣部中，尤其對四個角落進行補充，而可防止黏著層R1的四個角落超出容許範圍。即，即便未將補充用黏著劑R10塗佈於黏著層R1的整個緣部，亦可製造間隙所致的外觀不良或剝離所致的破損得以減少的高品質的顯示裝置用構件L。進而，亦可不將補充用黏著劑R10塗佈於黏著層R1的整個緣部，因而可縮短黏著劑補充處理的時間，從而黏著劑補充部6亦可為簡單的構成。 Each corner of the rectangular inner frame F of the cover panel S2 is a substantially right angle. In particular, in order to increase the display area, there are almost no Rs provided at the four corners. On the other hand, each corner of the edge portion of the rectangular adhesive layer R1 is applied to have a curved shape after being applied. At the edges of the adhesive layer R1, the four corners where the surface tension plays a large role form a larger curved surface, and the possibility that the gap exceeds the allowable range is also high. Therefore, the edge portion of the adhesive layer R1 can be formed within an allowable range even when the adhesive R is applied or shortly after the application. For curved surfaces, the four corners may exceed the allowable range. Therefore, it is possible to prevent the four corners of the adhesive layer R1 from exceeding the allowable range by supplementing the four corners in the edges of the adhesive layer R1. That is, even if the replenishing adhesive R10 is not applied to the entire edge portion of the adhesive layer R1, it is possible to produce a high-quality display device member L with reduced appearance defects due to gaps or damage due to peeling. Furthermore, the replenishing adhesive R10 may not be applied to the entire edge portion of the adhesive layer R1, so the time for replenishing the adhesive may be shortened, and the adhesive replenishing portion 6 may have a simple structure.

(5)顯示裝置用構件的製造裝置100進而包括對液晶面板S1及蓋面板S2進行拍攝的拍攝部5。黏著劑補充部6亦可根據拍攝部5所拍攝到的液晶面板S1及蓋面板S2的圖像，來供給補充用黏著劑R10。藉此，可對正確的位置補充黏著劑。 (5) The manufacturing apparatus 100 for a display device member further includes an imaging unit 5 that images the liquid crystal panel S1 and the cover panel S2. The adhesive replenishing section 6 may also supply the replenishing adhesive R10 based on the images of the liquid crystal panel S1 and the cover panel S2 captured by the imaging section 5. This allows the adhesive to be replenished to the correct position.

(6)顯示裝置用構件的製造裝置100進而包括搬送裝置4，該搬送裝置4將液晶面板S1及蓋面板S2在黏著劑塗佈裝置1與貼合裝置2之間搬送，拍攝部5及黏著劑補充部6設置於該搬送裝置4。貼合裝置2根據拍攝部5所拍攝到的液晶面板S1及蓋面板S2的圖像，進行液晶面板S1及蓋面板S2的位置對準。即，由拍攝部5拍攝到的圖像不僅用於決定補充用黏著劑R10的供給位置，亦用於貼合時的位置對準。即，無需針對各處理設置多個拍攝部5，從而可提高製造效率，且可使得零件個數減少。 (6) The manufacturing device 100 for a member for a display device further includes a transfer device 4 that transfers the liquid crystal panel S1 and the cover panel S2 between the adhesive coating device 1 and the bonding device 2, the imaging unit 5 and adhesion The agent replenishing section 6 is provided in the conveying device 4. The bonding device 2 aligns the positions of the liquid crystal panel S1 and the cover panel S2 based on the images of the liquid crystal panel S1 and the cover panel S2 captured by the imaging unit 5. That is, the image captured by the imaging unit 5 is used not only for determining the supply position of the replenishing adhesive R10, but also for position alignment during bonding. That is, it is not necessary to provide a plurality of imaging sections 5 for each process, so that manufacturing efficiency can be improved and the number of parts can be reduced.

[第2實施形態] [Second Embodiment]

[構成及作用] [Composition and role]

接下來，參照圖13(A)、圖13(B)對第2實施形態進行說明。另外，以後的實施形態中，對與第1實施形態的構成要素相同的構成要素，附上相同的符號並省略詳細說明。 Next, a second embodiment will be described with reference to Figs. 13 (A) and 13 (B). Bright. In the following embodiments, the same components as those in the first embodiment are denoted by the same reference numerals and detailed descriptions are omitted.

第1實施形態中，黏著劑補充部6設置於搬送裝置4，但第2實施形態中，對黏著劑補充部6設置於黏著劑塗佈裝置1的形態進行說明。如圖13(A)所示，黏著劑補充部6設置於支持單元11的上方的照射單元13的下游側。黏著劑補充部6包括收容補充用黏著劑R10的貯槽T10、及分注器62。第2實施形態中，分注器62如圖13(B)所示，成為在沿著液晶面板S1的橫斷方向延伸的支持部設置2個噴嘴的構成。2個噴嘴隔開與液晶面板S1的橫斷方向的寬度大致相同長度的間隔而設置，當液晶面板S1位於黏著劑補充部6的下方時，各個噴嘴位於沿著液晶面板S1的橫斷方向的邊上。 In the first embodiment, the adhesive replenishing section 6 is provided in the conveying device 4. However, in the second embodiment, the form in which the adhesive replenishing section 6 is provided in the adhesive coating device 1 will be described. As shown in FIG. 13 (A), the adhesive replenishing section 6 is provided on the downstream side of the irradiation unit 13 above the support unit 11. The adhesive replenishing section 6 includes a storage tank T10 containing a replenishing adhesive R10 and a dispenser 62. In the second embodiment, as shown in FIG. 13 (B), the dispenser 62 has a configuration in which two nozzles are provided in a support portion extending along the transverse direction of the liquid crystal panel S1. The two nozzles are provided at intervals of approximately the same length as the width of the liquid crystal panel S1 in the transverse direction. When the liquid crystal panel S1 is located below the adhesive replenishing section 6, each nozzle is located in the direction along the transverse direction of the liquid crystal panel S1. On the edge.

第2實施形態中，於黏著劑塗佈處理之後進行黏著劑補充處理。即，平台11a在塗佈單元12與照射單元13的下方移動，在載置於平台11a上的液晶面板S1形成著黏著層R1，進而使黏著層R1暫時硬化。然後，平台11a向下游方向進一步繼續移動，液晶面板S1的下游側的端部在到達黏著劑補充部6的下方後停止。 In the second embodiment, the adhesive replenishing process is performed after the adhesive coating process. That is, the stage 11 a moves under the coating unit 12 and the irradiation unit 13 to form an adhesion layer R1 on the liquid crystal panel S1 placed on the stage 11 a, and further temporarily hardens the adhesion layer R1. Then, the stage 11 a continues to move further in the downstream direction, and the end portion on the downstream side of the liquid crystal panel S1 stops after reaching the adhesive replenishing portion 6.

黏著劑補充部6自2個噴嘴噴出補充用黏著劑R10。補充用黏著劑R10附著於液晶面板S1的下游側端部的黏著層R1的兩角落。使平台11a再次向下游方向移動，液晶面板S1的上游側的端部到達黏著劑補充部6的下方後使平台11a再次停止。黏著劑補充部6自2個噴嘴噴出補充用黏著劑R10，藉此亦使補充用黏著劑R10附著於液晶面板S1的上游側端部的黏著層R1的兩角落上。 The adhesive replenishing section 6 ejects the replenishing adhesive R10 from two nozzles. The replenishing adhesive R10 is attached to both corners of the adhesive layer R1 on the downstream side end portion of the liquid crystal panel S1. The stage 11a is moved to the downstream direction again, and the end portion on the upstream side of the liquid crystal panel S1 reaches below the adhesive replenishing portion 6, and then the stage 11a is stopped again. Stick The agent replenishing section 6 ejects the replenishing adhesive R10 from the two nozzles, thereby causing the replenishing adhesive R10 to adhere to both corners of the adhesive layer R1 on the upstream side end portion of the liquid crystal panel S1.

所述平台11a的移動量及停止位置可預先根據液晶面板S1的尺寸等而加以規定，並可儲存於控制裝置7的記憶部。 The moving amount and stopping position of the platform 11 a can be specified in advance according to the size of the liquid crystal panel S1 and the like, and can be stored in a memory section of the control device 7.

另外，此處對由2根噴嘴構成黏著劑補充部6的示例進行了說明，但亦可由分別配置於與液晶面板的四個角落對應的位置的4根噴嘴構成。藉此，可一次進行針對四個角落的黏著劑補充處理，因而可縮短製造時間。 Although an example in which the adhesive replenishing section 6 is constituted by two nozzles has been described here, it may be constituted by four nozzles respectively disposed at positions corresponding to the four corners of the liquid crystal panel. Thereby, the adhesive replenishment processing for the four corners can be performed at one time, and thus the manufacturing time can be shortened.

[效果] [effect]

本實施形態中，黏著劑塗佈裝置1包括：塗佈單元12，將黏著劑R塗佈於液晶面板S1上；照射單元13，與塗佈單元12鄰接設置，藉由對塗佈於液晶面板S1上的黏著劑R照射能量，而使黏著劑R暫時硬化；以及平台11a，對液晶面板S1進行支持，使液晶面板S1相對於塗佈單元12及照射單元13而相對地移動，黏著劑補充部6相對於照射單元13而設置於移動方向的下游側，對藉由照射單元13而暫時硬化的黏著層R1的四個角落供給補充用黏著劑R10。 In this embodiment, the adhesive coating device 1 includes: a coating unit 12 that applies the adhesive R to the liquid crystal panel S1; an irradiation unit 13 that is disposed adjacent to the coating unit 12 and applies the coating to the liquid crystal panel The adhesive R on S1 is irradiated with energy to temporarily harden the adhesive R; and the platform 11a supports the liquid crystal panel S1 so that the liquid crystal panel S1 is relatively moved relative to the coating unit 12 and the irradiation unit 13, and the adhesive is replenished. The portion 6 is provided on the downstream side in the moving direction with respect to the irradiation unit 13, and supplies four corners of the adhesive layer R1 temporarily hardened by the irradiation unit 13 with a replenishing adhesive R10.

藉由將黏著劑補充部6設置於進行黏著劑塗佈處理的平台11a的移動方向上，即便不進行拍攝，亦可在相對正確的位置進行黏著劑的補充。而且，藉由將黏著劑補充部6設置於照射單元12的下游側，而可在使黏著劑暫時硬化後進行黏著劑的補充。藉此，補充用黏著劑R10不會被黏著層R1吸收。 By providing the adhesive replenishing portion 6 in the moving direction of the stage 11a where the adhesive coating process is performed, the adhesive can be replenished at a relatively accurate position even without taking an image. Further, by providing the adhesive replenishing portion 6 on the downstream side of the irradiation unit 12, the adhesive can be replenished after the adhesive is temporarily hardened. Thereby, the supplementary adhesive R10 is not absorbed by the adhesive layer R1.

[其他實施形態] [Other embodiments]

(1)所述實施形態中，對包括輸送機40作為搬送液晶面板S1及蓋面板S2的搬送部的搬送裝置4的示例進行了說明，但不限於此。搬送部例如如圖14所示，亦可將包括上下平行配置的兩根臂41a、臂41b的保持部件41配置成能夠在軌道42上行走。 (1) In the above-mentioned embodiment, the example of the conveyance apparatus 4 including the conveyor 40 as a conveyance part which conveys the liquid crystal panel S1 and the cover panel S2 was demonstrated, but it is not limited to this. As shown in FIG. 14, for example, the conveyance unit may include a holding member 41 including two arms 41 a and 41 b which are arranged in parallel vertically, so as to be able to travel on the rail 42.

液晶面板S1及蓋面板S2分別由兩根臂41a、臂41b保持且以相向的方式在軌道42上搬送。拍攝部5及黏著劑補充部6以位於軌道42上的兩根臂41a、臂41b之間的方式配置。此時，拍攝部5例如可在上下兩側具備相機。藉此，可同時拍攝上下的面板。 The liquid crystal panel S1 and the cover panel S2 are held by two arms 41a and 41b, respectively, and are carried on the rails 42 in a facing manner. The imaging section 5 and the adhesive replenishing section 6 are arranged between the two arms 41 a and 41 b on the rail 42. In this case, the imaging unit 5 may include cameras on both the upper and lower sides, for example. Thereby, the upper and lower panels can be photographed simultaneously.

黏著劑補充部6可設為與第1實施形態相同的構成，但為了亦能夠對保持於上側的面板進行黏著劑補充處理，宜為使用射流噴嘴。 The adhesive replenishing section 6 may have the same configuration as the first embodiment, but a jet nozzle is preferably used in order to enable the adhesive replenishing process to be performed on the panel held on the upper side.

(2)所述實施形態中，對黏著層R1的緣部的四個角落供給補充用黏著劑R10，但不僅限於四個角落，亦可對四個角落以外的部分供給補充用黏著劑R10。例如，如圖15(A)、圖15(B)所示，亦可對整個緣部供給。此時，黏著劑補充部6可設為與所述實施形態相同的構成，但宜使用能夠連續地塗佈少量的黏著劑的多噴嘴或針形噴嘴。而且，在R大的黏著層R1的四個角落及其他直線部分，亦可改變補充用黏著劑R10的塗佈量。 (2) In the above-mentioned embodiment, the supplemental adhesive R10 is supplied to four corners of the edge portion of the adhesive layer R1. However, the supplementary adhesive R10 is not limited to the four corners, and may be supplied to portions other than the four corners. For example, as shown in Figs. 15 (A) and 15 (B), the entire edge portion may be supplied. In this case, the adhesive replenishing section 6 may have the same configuration as the embodiment described above, but it is preferable to use a multi-nozzle or a needle nozzle that can continuously apply a small amount of the adhesive. In addition, the coating amount of the replenishing adhesive R10 can also be changed at the four corners of the large R adhesive layer R1 and other straight portions.

而且，所述實施形態中，例如如圖17(A)、圖17(B) 或圖10(A)、圖10(B)所示，對在尺寸小的液晶面板S1的大致整個面設置黏著層R1的示例進行了說明，但亦可在尺寸大的蓋面板S2設置黏著層R1。該情況下，當然要將與貼合的液晶面板S1的尺寸相應的大小的黏著層R1以面狀設置於蓋面板S2。 In the above-mentioned embodiment, for example, as shown in FIGS. 17 (A) and 17 (B) Alternatively, as shown in FIGS. 10 (A) and 10 (B), an example in which the adhesive layer R1 is provided on substantially the entire surface of the small-sized liquid crystal panel S1 has been described, but an adhesive layer may be provided on the large-sized cover panel S2. R1. In this case, it is needless to say that the adhesive layer R1 having a size corresponding to the size of the bonded liquid crystal panel S1 is provided on the cover panel S2 in a planar shape.

而且，所述實施形態中，以蓋面板S2的內框F為矩形形狀且四個角落被倒角、並且剖面觀察為直角者為例進行了說明，但不限於此。例如，亦可使用四個角落不被倒角即水平觀察時為大致直角者。或者，亦可使用剖面觀察並非為大致直角而例如為R形狀等各種形狀者。 Furthermore, in the embodiment described above, the case where the inner frame F of the cover panel S2 has a rectangular shape, the four corners are chamfered, and the cross-section is right-angled is described as an example, but it is not limited thereto. For example, the four corners may be used without being chamfered, that is, when they are viewed at a right angle when viewed horizontally. Alternatively, those having various shapes such as an R shape other than a substantially right-angled cross-sectional view may be used.

(3)顯示裝置用構件的製造裝置100亦可包括在黏著劑塗佈裝置1、貼合裝置2及硬化裝置3的前後或其間進行其他步驟的裝置。例如，亦可包括將已完成的液晶顯示面板捆包的捆紮(taping)單元等。而且，在根據黏著劑的種類而不需要硬化處理的情況下或利用另外的裝置進行硬化處理的情況下等，亦可為無硬化裝置3的顯示裝置用構件的製造裝置100。 (3) The manufacturing apparatus 100 for a member for a display device may include a device that performs other steps before or after the adhesive coating device 1, the bonding device 2, and the curing device 3. For example, it may include a taping unit that packs the completed liquid crystal display panel. In addition, when the hardening treatment is not required depending on the type of the adhesive or when the hardening treatment is performed by another device, the manufacturing device 100 for a display device member without the hardening device 3 may be used.
