Description

本発明は、曲面貼合装置及びその貼合方法に関し、特に、気体充填型の少なくとも１つの気体充填孔を利用して気圧フィルムに対して気体充填し、軟性部材の中央を伴って隆起させ、曲面物体と軟性部材を貼合させる時、中心から外へ貼合でき、気体の完全な排出を確保し、曲面物体と軟性部材の間に気泡、皺が発生しなくようにし、全体の歩留まりを向上する曲面貼合装置及びその貼合方法に関する。   The present invention relates to a curved surface bonding apparatus and a method of bonding the same, and in particular, at least one gas-filled gas-filled hole is used for gas filling of a pressure film and raised with the center of the soft member When bonding a curved object and a flexible member, it can be bonded from the center to the outside, ensuring complete discharge of gas, preventing bubbles and wrinkles from being generated between the curved object and the flexible member, and achieving the overall yield. The present invention relates to a curved surface bonding apparatus to be improved and a bonding method thereof.

現在の製造産業は、労働力の不足、加工作業が環境に対して汚染を招くという深刻な問題に直面しており、環境意識の向上、人件費、経営コスト等が上昇する状況の下、更に労力が密集して技術的に密集した圧力に変わり、業者の多くは、産業を外へ移すか、外国籍労働力を引き込む方式で生産コストの上昇に応じるか、生産ライン自動化技術を運用して治具で加工を補助する作業モデルによって経営体質を改善しコストを低減し、これにより、人件費を削減、製造工程時間を節減して生産能力を向上する目的を達成している。   The current manufacturing industry is facing a serious problem that labor shortages and processing operations cause pollution to the environment, and further increase in environmental awareness, labor costs, management costs etc. Dense labor and technically dense pressure, many traders either move the industry out, respond to rising production costs in a manner that draws in foreign labor, or operate production line automation technology Work models that use jigs to assist in processing improve the management structure and reduce costs, thereby achieving the purpose of reducing labor costs, saving manufacturing process time, and improving production capacity.

また、液晶表示器、フィルムタッチパネルの製作の技術は、絶え間なく研究開発、精進され、新世代の製品の応用は、何れも軽く、薄く、省エネルギー、低輻射、可撓性又は曲面及び大型化の方向に設計され、その目的は、何れも人類に比較的大きな視覚インタフェース及び更に高解像度な色彩を提供するためであり、人類に極めて良好な利便性及び娯楽性をもたらいる。
従って、表示インタフェースは、産業が注力する焦点となっており、関連業者が資源を投じて新たな表示技術、新たな応用を開発し、共通で人類の視覚的享受を向上するために努力しており、それは、一般の液晶パネル、タッチパネル等のほとんどが平面であり、そのパネルの貼合技術の発展は、既に相当成熟しており、貼合技術が絶え間なく改良されているが、極大的な技術革新も相対的に困難となっている。 In addition, the technology for manufacturing liquid crystal displays and film touch panels is constantly researched, developed, and promoted, and the applications of new generation products are all light, thin, energy saving, low radiation, flexible or curved surface and large size Designed in a direction, the purpose is to provide humanity with a relatively large visual interface and higher resolution colors, and provide humanity with extremely good convenience and entertainment.
Therefore, the display interface has become the focus of the industry's focus, and related companies are investing resources to develop new display technologies, new applications, and strive to improve the common human visual enjoyment Most of general liquid crystal panels, touch panels, etc. are flat, and the development of bonding technology of the panel is already quite mature, and bonding technology is continuously improved, but it is maximal Technological innovation is also relatively difficult.

しかしながら、パネル製造業者が開発した新たな有機発光ダイオード（ＯＬＥＤ）の可撓性曲面のパネル表示技術は、従来の液晶パネルに比較して更に広く、コントラストが良好で、低電力消耗で高い反応速度等の利点を有し、従って、曲面貼合技術の開発が一つの重要な鍵となっており、曲面基板を安定して貼合できる方式の追求が必須となっている。   However, the panel display technology of the flexible curved surface of the new organic light emitting diode (OLED) developed by the panel manufacturer is wider than conventional liquid crystal panels, has good contrast, high reaction speed with low power consumption. And the development of a curved surface bonding technique is one of the key keys, and the pursuit of a method capable of stably bonding a curved surface substrate is essential.

しかしながら、液晶表示器、フィルムタッチパネルの需要の急速な成長に伴って、生産効率及び歩留まりを如何に向上するかは、製造業者の気体するところであり、パネルプロセスのボトルネックは、主に接着又は貼合プロセスにあり、例えば、偏光板、ガラス基板、光学フィルム、タッチフィルム、又はフレキシブルアクティブマトリクス有機発光ダイオードディスプレイパネルの上下型、機能フィルム及びパッケージフィルム等は、何れもその表面に厳格な要求があり、各種２つの基板の間の貼合において、透光性が良好な光学接着剤（ＯＣＲ接着剤）又は固体光学接着剤（ＯＣＡ接着剤）を使用して結合を行うが、一般の接着にプレス接合する技術は、容易に気泡が発生し、プロセス時間が長く、歩留まりが低い等の問題があり、更に、大型のパネルの要求に応じることができない。   However, with the rapid growth of demand for liquid crystal displays and film touch panels, how to improve the production efficiency and yield is the gas of the manufacturer, and the bottleneck of the panel process is mainly adhesion or sticking In the process, for example, polarizing plates, glass substrates, optical films, touch films, or upper and lower types of flexible active matrix organic light emitting diode display panels, functional films and package films etc. all have strict requirements on their surfaces. Bonding is performed using an optical adhesive (OCR adhesive) or a solid optical adhesive (OCA adhesive) with good transparency in bonding between various two substrates, but pressing for general bonding Bonding technology has problems such as easy generation of bubbles, long process time, low yield, etc. It is not possible to meet the demands of a large panel.

従って、製造業者は、以下の２種の方式で貼合作業を行い、そのうち１種は、スクリーンを利用して基板に吸着して他の基板の下方に移動させ、機台のローラがスクリーンのメッシュ面で加圧回転を行い、基板を他の基板の上に回転して貼合した後、一体に結合し、且つ２つの基板の間の貼合過程は、真空状態で気泡を発生することがなく、光学屈折の問題を招くことができず、従って、貼合過程の歩留まりを向上できるが、該スクリーンの回転貼合の過程で、スクリーンが吸着する基板が確実に他の基板に貼付できるようにし、ローラが比較的大きな作用力を加えて圧延を行い、スクリーンの繰り返し使用の下、引っ張りを受けて破裂し易く、スクリーンの真空が破れて基板に緊密に吸着できなくなり、構造全体が相当不安定となり、パネル貼合プロセス上の品質及び歩留まりに影響を及ぼし、生産能力及びコストの要求を満たすことが困難である。   Therefore, the manufacturer performs the bonding operation in the following two methods, one of which is adsorbed onto the substrate using the screen and moved to the lower side of the other substrate, and the roller of the machine is the screen After pressing and rotating on the mesh surface and rotating and pasting the substrates onto another substrate, they are bonded together and the process of bonding between the two substrates generates bubbles in a vacuum state. And the problem of optical refraction can not be caused, and thus the yield of the bonding process can be improved, but in the process of rotational bonding of the screen, the substrate to which the screen is adsorbed can be reliably bonded to another substrate So that the roller rolls with a relatively large force and is subject to tension and rupture under repeated use of the screen, the screen vacuum is broken and can not be tightly attached to the substrate, and the entire structure is considerable Become unstable Affect the quality and yield of the bonding process, it is difficult to meet the requirements of production capacity and cost.

また、そのパネルのもう１種の貼合方式は、先ず、雄型に基板を位置決めし、雌型下方に曲面パネルを位置決めし、雄雌型を相互に押圧し、基板に曲面パネルの押圧を受けさせてその弧度に符合させ、曲面パネルと基板を一体に接着させるが、この種の製造方式の場合、曲面パネルが基板に押し込まれる時、その基板表面は、曲面パネルと接触を形成し、その接触の点が単点で受ける圧力が大きく、瑕疵、損壊等の欠陥を発生し易い問題があり、且つ基板表面に塗布した接着剤は、曲面パネルを基板に押し込む過程で曲面パネルの屈曲部が切削を受けて脱落し易く、曲面パネル及び基板を適切に相互に接合させることができないか、或いは、一部の接着剤が外に溢れて歩留まりが低下する状況の発生を招く。   In addition, in another type of bonding method of the panel, first, the substrate is positioned on the male mold, the curved panel is positioned below the female mold, the male and female molds are mutually pressed, and the curved panel is pressed against the substrate. The curved panel and the substrate are bonded together, but with this type of manufacturing method, when the curved panel is pressed into the substrate, the substrate surface makes contact with the curved panel, There is a problem that the pressure at the point of contact is large at a single point, and there is a problem that defects such as wrinkles and damage are easily generated, and the adhesive applied to the substrate surface is a bent portion of the curved panel in the process of pushing the curved panel into the substrate. However, it is likely that the curved panel and the substrate can not be properly joined to each other or that a part of the adhesive overflows and the yield is reduced.

従って、如何に精密な貼合、プロセスの歩留まり及び生産能力を向上する要求を達成するかは、この業者が研究改善の方向を欲するところとなっている。   Therefore, how to meet the requirements for improving precision bonding, process yield and production capacity is what this trader wants to have a direction for research improvement.
