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，且現今物聯網(Internet of things，IoT)及工業4.0(Industry4.0)時代來臨，連網裝置的數量、應用大幅地增加，而且這些連網裝置彼此間的通信與互動等，大多都是在無人介入的情況下自動進行，所以會有越來越多的設備需要在無人操作的情況下自動進行彼此間的協同運作，以完成特定整體製造流程，然而，在無人自動化的操作下，每一個工作站的良率、精準度都十分地重要，才不會因為低良率、精準度而影響作業流暢度，甚至發生停機的情況，導致延誤整體製造流程 。 According to this, today’s manufacturing industry is facing serious problems of shortage of labor demand and processing operations that easily pollute the environment. With rising environmental awareness, labor and operating costs, etc., as well as labor-intensive and technology-intensive pressures , The industry mostly uses production line automation technology and fixture-assisted processing operation mode to improve business quality and reduce costs, so as to achieve the purpose of reducing manpower, saving manufacturing hours and increasing productivity, and the Internet of things (IoT) With the advent of the Industry 4.0 era, the number and applications of connected devices have greatly increased, and the communication and interaction between these connected devices are mostly carried out automatically without human intervention, so there will be More and more devices need to automatically cooperate with each other without unmanned operation to complete a specific overall manufacturing process. However, under unmanned automated operation, the yield and accuracy of each workstation are very important , It will not affect the smoothness of the operation due to the low yield and accuracy, or even the downtime, which causes delays in the overall manufacturing process .

再者，由於液晶顯示器、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、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。 Furthermore, due to the continuous research and development and advancement of the technology of liquid crystal display and touch panel production, the new generation of product applications are designed to be lighter, thinner, energy-saving, flexible or curved, and larger in size. All are to provide humans with a wider visual interface and higher-resolution colors, and to bring great convenience and fun to humans. Therefore, the display interface has become the focus of the industry, and relevant manufacturers are not willing to invest resources to develop new The display technology and new applications of the company are working together to enhance the visual enjoyment of human beings.

然而，目前觸控面板必須裝設於電子產品的表面以供使用者進行觸控輸入與操作，亦或者貼合於顯示面板表面上，以提供顯示觸控功能，而在現有技術中，其顯示器面板與觸控面板主要是透過雙面黏合光學膠布(Optical Clear Adhensive，OCA)或可經由紫外線光照射固化的光學膠脂(Optical Clear Resin，OCR)來黏合為一體，由於，該光學膠脂具有高重工、抑制外部光照與背光所導致的光散射情況之特性，且光學膠脂受到紫外光線(UV光)照射後，亦包括有與玻璃相近的折射率和透光率、耐黃變及柔軟可承受多種不同基板的膨脹收縮率等諸多優點，進而使光學膠脂於實際應用時，可供抵擋貼合時高低溫差變化，藉此使光學膠脂成為各式的觸控面板、大尺寸玻璃基板或其它基板間的貼合與組裝製程中的主流運用。 However, the current touch panel must be installed on the surface of the electronic product for the user to perform touch input and operation, or be attached to the surface of the display panel to provide the display touch function. In the prior art, the display The panel and the touch panel are mainly bonded together through a double-sided adhesive optical clear adhesive (OCA) or an optical clear resin (OCR) that can be cured by ultraviolet light. Because the optical adhesive has It has the characteristics of high heavy industry, inhibiting the light scattering caused by external light and backlight, and after the optical glue is irradiated by ultraviolet light (UV light), it also includes the refractive index and light transmittance similar to glass, yellowing resistance and softness It can withstand the expansion and contraction rate of a variety of different substrates and many other advantages, so that the optical glue can resist the change of high and low temperature difference during lamination in actual application, so that the optical glue can become a variety of touch panels and large-size glass. Mainstream applications in the bonding and assembly processes between substrates or other substrates.

而該光學膠脂(OCR)在顯示器面板與觸控面板貼合的過程中，其一般廠商主要為利用口字形的光學膠脂來進行塗佈貼合作業，但於實際應用時，其因面板應用種類、款式甚多，導致面板的形狀、尺寸大小也有諸多不同，所以為了確保光學膠脂的貼合、延展性及減少溢膠， 以致於光學膠脂不能一昧使用口字形來進行塗佈貼合，而使光學膠脂必須以異形的塗佈形狀來進行貼合作業，但是，由於一般光學膠脂塗佈的製程中，其須利用狹縫式模具來進行狹縫式塗佈(Slit Coating)，以使面板表面上形成出平整度良好的光學膠脂塗佈層，然而，該異形之光學膠脂過程中，因異形之光學膠脂的形狀、膠層厚度及用量很難透過狹縫式塗佈精准控制，導致容易發生溢膠的情況，以致於清潔費時、費力，且產品良率較差，藉此無法有效連續的進行自動化製程，進而嚴重影響工時、產能及產品良率，以無法符合工業4.0的產業趨勢。 In the process of bonding the display panel and the touch panel of the optical resin (OCR), the general manufacturer mainly uses the mouth-shaped optical resin for the coating and bonding industry. However, in actual application, due to the panel There are many types of applications and styles, resulting in many differences in the shape and size of the panel. Therefore, in order to ensure the adhesion, ductility and reduce the overflow of the optical glue, As a result, optical adhesives can’t be coated and bonded in a mouth shape, and optical adhesives must be applied in special-shaped coating shapes. However, due to the general optical adhesive coating process, its It is necessary to use a slit mold to perform slit coating (Slit Coating) so that a smooth optical grease coating layer is formed on the surface of the panel. However, in the process of the irregular optical grease, due to the irregular shape It is difficult to precisely control the shape, thickness and dosage of the optical adhesive through slit coating, which leads to the possibility of glue overflow, which makes cleaning time-consuming and labor-intensive, and the product yield rate is poor, so that it cannot be effectively and continuously carried out. Automated manufacturing processes have severely affected man-hours, productivity, and product yields, making them unable to comply with the industry trend of Industry 4.0.

是以，要如何設法解決上述習用之缺失與不便，即為從事此行業之相關業者所亟欲研究改善之方向所在。 Therefore, how to try to solve the above-mentioned deficiencies and inconveniences of conventional use is the direction that relevant industries in this industry urgently want to study and improve.

The semi-cured optical adhesive is then cut with a cutting device on the surface of the semi-cured optical adhesive and along the periphery of the soft component contour to form grooves, so that the semi-cured optical adhesive is formed on the surface of the soft component Produce special-shaped optical glue that conforms to the shape of the soft component, and then remove the residual optical glue other than the film and the special-shaped optical glue from the sheet It has the effect of easily making special-shaped optical adhesives using automated methods. It is not necessary to re-align and attach special-shaped optical adhesives to the surface of soft components to reduce the risk of damage. At the same time, it simplifies the manufacturing process, and because the cutting device cuts grooves directly along the contour of the soft component, the profiled optical glue and the outer edge of the soft component will be on the same plane, which can further reduce the softness. The error between the component and the special-shaped optical adhesive further improves the overall manufacturing yield, and enables the overall automated manufacturing process to proceed smoothly, and achieves the goal of reducing the overall manufacturing time and cost.

本發明之次要目的乃在於該基材之黏著層為紫外光固化解離膠帶，當紫外光線固化裝置進行紫外光固化作業時，可同時解離紫外光固化解離膠帶，以便於薄膜從片材之基材上拆離，進而提升撕離作業的流暢度，且黏著層解離後可減少撕離時的應力，藉此可達到防止薄膜撕離時，其片材之基材發生損壞、永久變形情況之目的。 The secondary purpose of the present invention is that the adhesive layer of the substrate is a UV-curable dissociative tape. When the UV-curing device performs UV curing operations, the UV-curable dissociative tape can be dissociated at the same time, so that the film can be removed from the base of the sheet. The material is detached, thereby improving the smoothness of the tearing operation, and after the adhesive layer is dissociated, the stress during tearing can be reduced, so as to prevent the substrate of the sheet from being damaged and permanently deformed when the film is torn off. purpose.
