Description

按，現今製造產業面臨勞工需求短缺、加工作業容易對環境造成污染的嚴重問題，並在環保意識高漲、人工與經營所需成本等提高的情況下，以及勞力密集而轉型成技術性密集的壓力，業者大都以產業外移或引進外籍勞工的方式來因應生產成本的上漲，或者是運用生產線自動化技術及治具輔助加工的作業模式來改善經營體質與降低成本，藉此達到縮減人力、節省製造工時而提高產能之目的。 According to the present, the manufacturing industry is facing serious problems of shortage of labor demand, easy processing operations to cause pollution to the environment, and under the situation of rising environmental awareness, increased labor and management costs, and the pressure of labor-intensive and transition to technology-intensive Most of the operators respond to the increase in production costs by moving the industry or importing foreign labor, or use the operation mode of production line automation technology and fixture-assisted processing to improve their physical fitness and reduce costs, thereby reducing labor and manufacturing. The goal is to increase productivity by working hours.
再者，由於液晶顯示器、薄膜觸控面板製作的技術不斷研發與精進，使得新一代的產品應用皆朝向更為輕、薄、省能源、低輻射、可撓性或曲面以及大尺寸化的方向設計，其目的都是為了能提供人類更寬大的視覺介面與更高解析度的色彩，並為人類帶來極佳的便利性與樂趣，因此，顯示介面已成為產業關注的焦點，相關廠商莫不投注資源開發新的顯示技術、新應用，共同為了提升人類的視覺享受而努力，而其因一般液 晶面板、觸控面板等大都為一平面，其面板之貼合技術發展已經相當的成熟，雖然貼合技術不斷的改進，但要有極大的創新技術也相對的困難，不過隨著面板製造廠商研發出新的有機發光二極體(OLED)可撓性曲面之面板顯示技術，相較於傳統液晶面板具有視角更廣泛、對比度更佳、低耗電及高反應速率等優點，所以曲面貼合技術的開發是一重要的關鍵，必須尋求能夠穩定的貼合曲面基板之方式。 Furthermore, due to the continuous research and development of the technology for the production of liquid crystal displays and thin-film touch panels, the new generation of product applications are all moving towards lighter, thinner, energy-saving, low-radiation, flexible or curved surfaces, and large dimensions. The purpose of the design is to provide a wider visual interface and higher resolution colors for human beings, and bring excellent convenience and fun to human beings. Therefore, the display interface has become the focus of the industry. Betting resources develop new display technologies and new applications, and work together to improve human visual enjoyment. Crystal panels, touch panels, etc. are mostly flat, and the development of the bonding technology of their panels has been quite mature. Although the bonding technology has been continuously improved, it is relatively difficult to have great innovations. However, as panel manufacturers Developed a new organic light-emitting diode (OLED) flexible curved panel display technology. Compared with traditional LCD panels, it has the advantages of wider viewing angle, better contrast, low power consumption and high response rate. The development of technology is an important key, and it is necessary to find a way to stably attach curved substrates.
然而，隨著液晶顯示器、薄膜觸控面板需求的高速成長，如何提高生產效率及良率是所有製造廠商的期待，面板製程的瓶頸主要是在塗膠及貼合製程，例如偏光板、玻璃基板、光學膜、觸控膜，或者是可撓式主動矩陣有機發光二極體顯示面板之上、下膜、功能膜及封裝膜等，都會對其表面有嚴格的要求，並於各種二基板間的貼合上，常使用透光度較好之光學膠(OCR膠，俗稱水膠)或固態光學膠(OCA膠)作結合，但一般塗膠再壓合的技術容易產生有氣泡、製程時間長與良率低等問題，更加無法應付大尺寸面板的需求。 However, with the rapid growth of demand for liquid crystal displays and thin-film touch panels, how to improve production efficiency and yield is the expectation of all manufacturers. The bottleneck of the panel manufacturing process is mainly the gluing and bonding process, such as polarizing plates and glass substrates. , Optical film, touch film, or flexible active matrix organic light-emitting diode display panel, the top film, the bottom film, the functional film and the packaging film, etc., will have strict requirements on their surface, and between the various two substrates For bonding, optical glue (OCR glue, commonly known as water glue) or solid optical glue (OCA glue) with better light transmittance is often used for bonding. However, the general glue coating and compression technology is easy to produce bubbles and process time. Problems such as long and low yield, can not even meet the needs of large size panels.
因此製造廠商便會透過下列二種方式來進行貼合作業，其中一種是利用網板吸附於基板位移至另一基板下方，再由機台之滾筒在網板的網面上進行加壓滾動，使基板滾貼於另一基板上後結合成為一體，且二基板間之貼合過程為真空狀態不會產生氣泡，便不會導致有光學折射的問題，所以可提高貼合製程的良率，惟該網板滾貼的過程中，為了使網板吸附之基板能夠確實的貼著於另一基板上，滾筒便會施加較大作用力進行滾壓，造成網板反覆的使用下容易受到拉扯而破裂，導致網板破真空而無法緊密吸附於基板上，整體結構相當的不穩定，進而影響到面板貼合製程 上的品質與良率，難以達成產能及成本的要求。 Therefore, the manufacturer will use the following two methods to carry out the paste cooperation industry. One is to use the screen to attract the substrate to the bottom of the other substrate, and then the roller of the machine performs pressure rolling on the screen of the screen. The substrate is rolled and bonded to another substrate to be integrated into one body, and the bonding process between the two substrates is in a vacuum state without generating bubbles, which will not cause optical refraction. Therefore, the yield of the bonding process can be improved. However, in the process of rolling the stencil, in order to make the substrate adsorbed by the stencil adhere to another substrate, the roller will apply a large force to perform rolling, which will cause the stencil to be easily pulled under repeated use. The rupture caused the stencil to break the vacuum and could not be closely adhered to the substrate. The overall structure was quite unstable, which affected the panel bonding process. In terms of quality and yield, it is difficult to meet the requirements of production capacity and cost.
另外，其面板還有另一種貼合方式，係先將公模上定位有基板，並於母模下方定位有曲面面板，再將公母模相互擠壓，以使基板受到曲面面板擠壓而符合其弧度，進而使曲面面板與基板黏合為一體，然而，在為此種製造方式的情況下，當曲面面板壓入於基板上時，其基板表面會與曲面面板形成接觸，其接觸的點容易因單點受到的壓力過大而產生瑕疵、損壞等缺陷問題，且基板表面塗佈之黏著劑在曲面面板壓入於基板的過程中，亦容易受到曲面面板的彎曲段切削掉落，而使曲面面板與基板無法適當地相互接合，或者產生部份黏著劑向外溢出而導致不良率提高之情形發生。 In addition, the panel also has another bonding method. First, the substrate is positioned on the male mold, and the curved panel is positioned below the female mold, and then the male and female molds are pressed against each other, so that the substrate is squeezed by the curved panel. In accordance with its curvature, the curved panel is bonded to the substrate as a whole. However, in the case of this manufacturing method, when the curved panel is pressed onto the substrate, the substrate surface will contact the curved panel, and the point of contact It is easy to produce defects such as flaws and damage due to excessive pressure at a single point, and the adhesive coated on the substrate surface is also easily cut and dropped by the curved section of the curved panel during the process of pressing the curved panel into the substrate. The curved panel and the substrate cannot be properly bonded to each other, or a part of the adhesive overflows outward, resulting in an increase in the defective rate.
是以，要如何達到精密貼合、提升製程良率及產能的要求，此即為從事於此行業者所亟欲研究改善之方向所在。 Therefore, how to meet the requirements of precision lamination, improve process yield and production capacity is the direction for those who are engaged in this industry to study and improve.
故，發明人有鑑於上述缺失，乃搜集相關資料，經由多方評估及考量，並以從事於此行業累積之多年經驗，經由不斷試作及修改，始設計出此種曲面貼合裝置及其貼合方法的發明專利者。 Therefore, in view of the above-mentioned shortcomings, the inventors collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, and continued to make trials and modifications, they began to design such curved surface bonding devices and their bonding. Method inventor.
本發明之主要目的乃在於該充氣模具所具之座體表面設有凸出之擋塊，並於擋塊頂面周圍處形成有彎曲面，再於擋塊內貫穿有供進行充氣作業之至少一個充氣孔，而座體上設有罩覆於至少一個充氣孔處之氣壓膜，其氣壓膜對應於至少一個充氣孔位置處設有供彈性膨脹或縮小之作動部，再於作動部周圍處形成有供服貼於彎曲面上之導弧面，且該充氣模具上方所設之治具具有移動機構，並於移動機構上結合有承載膜，其承 載膜表面為供定位有軟性元件，而承載膜底面為供抵貼於氣壓膜上，又於治具上方設有吸附模具，其並吸附模具具有供吸附曲面物件之吸附平台，當曲面物件與軟性元件相互貼合時，為可先透過充氣模具之至少一個充氣孔來對氣壓膜進行充氣，以帶動軟性元件中央處隆起呈拱狀，即可先以軟性元件中心來確實接觸至曲面物件中心，再由中心朝外延伸壓合呈一緊密貼合定位，以確保曲面物件與軟性元件之間的氣體完全朝外擠壓出，進而使曲面物件與軟性元件之間無任何氣泡產生，並可防止軟性元件於貼合過程中產生皺褶，而可精確緊密貼合於曲面物件上，藉此達到提升製程、產品良率之目的。 The main purpose of the present invention is that the surface of the seat of the inflatable mold is provided with a protruding stopper, and a curved surface is formed around the top surface of the stopper, and at least the inflating operation is penetrated in the stopper. An inflatable hole, and the seat body is provided with an air pressure film covering at least one inflatable hole, and the air pressure film is provided with an actuating part for elastic expansion or contraction at a position corresponding to the at least one inflation hole, and then around the actuating part An arc-guiding surface is formed for the service to be attached to the curved surface, and the jig provided above the inflatable mold has a moving mechanism, and a bearing film is combined with the moving mechanism. The surface of the carrier film is for positioning soft components, and the bottom surface of the carrier film is for abutting on the air pressure film. An adsorption mold is provided above the jig. The adsorption mold has an adsorption platform for adsorbing curved objects. When the soft components are attached to each other, the air pressure film can be inflated through at least one inflation hole of the inflatable mold to drive the center of the soft component into an arch shape, and then the center of the soft component can be used to contact the center of the curved object. , And then extended from the center to the outside to form a tight fit to ensure that the gas between the curved object and the soft element is completely squeezed out, so that there is no air bubble between the curved object and the soft element, and It can prevent the soft components from wrinkling during the bonding process, and can accurately and tightly fit on curved objects, thereby achieving the purpose of improving the process and product yield.
本發明之次要目的乃在於該治具透過移載機構作動後，會與充氣模具結合，其治具之承載膜受到充氣模具之氣壓膜凸出的部份撐抵而拉伸出弧面，以連帶軟性元件成形出曲面，即可透過事先成形出曲面之軟性元件來與曲面物件貼合過程中，可避免因曲徑的不同而使軟性元件表面受到過度的擠壓，以防止軟性元件產生瑕疵、損壞等缺陷問題，且亦可避免軟性元件之黏著層受到曲面物件削掉的情況發生，進而使軟性元件確實密合於曲面物件上，藉此達到提升整體製程良率之目的。 The secondary object of the present invention is that the jig is combined with an inflatable mold after the jig is moved through the transfer mechanism, and the supporting film of the jig is stretched out by the convex part of the air pressure film of the inflation mold to stretch out the arc surface. Forming a curved surface with associated soft components can prevent the soft component surface from being excessively squeezed due to the difference in the bending radius during the lamination process of the curved soft component in advance. Defects such as defects and damages can also avoid the situation where the adhesive layer of the soft component is cut off by the curved object, so that the soft component is firmly adhered to the curved object, thereby achieving the purpose of improving the overall process yield.
