Description
本發明係有關於一種以噴墨製程將玻璃噴印成具金屬外觀之方法，尤其是指一種以噴印方式於玻璃進行表面處理，使玻璃外觀呈現金屬質感，不僅能更為快速進行表面處理，達到多樣化、全彩及漸層等效果，節省一般印刷製程所需的製版開版費用及時間，並可減少油墨之使用，除降低成本外也較符合環保，且如此組合之塗層經烘烤後可以滿足消費性電子產品的相關性能測試，提高了應用的領域，而在其整體施行使用上更增實用功效特性者。The invention relates to a method for printing glass into a metallic appearance by an inkjet process, in particular to a surface treatment of glass by printing, so that the appearance of the glass is metallic, and the surface treatment can be performed more quickly. To achieve diversification, full color and gradual effects, save the cost and time of plate making required for general printing processes, and reduce the use of ink, in addition to reducing costs, it is also more environmentally friendly, and the combination of such coatings After baking, it can meet the relevant performance test of consumer electronic products, improve the field of application, and increase the utility performance characteristics in its overall implementation.
按，智慧型手機已進入成熟的階段，各家手機品牌在功能評比上已大同小異，使得手機的外型搶眼吸睛與否決定消費者購買換機的意願；而由於人體的手心係向內具有弧度，使得３Ｄ曲面後殼的曲線結構設計正好能符合人體工程學，加之其弧形邊緣的觸控功能，可大大的提升消費者的握感體驗，使得其逐漸被廣泛的應用在智慧型手機上，且隨著３Ｄ曲面結構設計在智慧型手機應用上的流行，如何增強３Ｄ曲面結構件的表面裝飾性能，也再次引起了整個產業的高度關注。According to the smart phone, the mobile phone brand has entered a mature stage, and the mobile phone brands have been similar in function evaluation, making the appearance of the mobile phone eye-catching or not, determining the willingness of consumers to purchase the machine; and since the body of the human body is inward The curvature makes the curved structure of the 3D curved back shell just in line with ergonomics, and the touch function of its curved edge can greatly enhance the consumer's grip experience, making it gradually widely used in smart phones. On the other hand, with the popularity of 3D surface structure design in smart phone applications, how to enhance the surface decoration performance of 3D curved structural parts has once again caused great concern in the whole industry.
另，由於一般用戶普遍認為塑料機殼材質較為低檔，使得金屬、玻璃、陶瓷等超硬材質得到了更多智慧型手機廠商們的認可；而由於玻璃具有輕薄、透明潔凈等特點，且隨著新通訊技術的使用臨近及無線充電技術的應用，金屬機殼的屏蔽效果成為重大瓶頸，加上玻璃之加工成形性較佳，使得玻璃材質製作之機殼已開始取代其它材料。In addition, because the general user generally believes that the plastic casing material is relatively low-grade, the super-hard materials such as metal, glass and ceramics have been recognized by more intelligent mobile phone manufacturers; and because the glass has the characteristics of lightness, transparency and cleanliness, The use of new communication technologies and the application of wireless charging technology, the shielding effect of the metal casing has become a major bottleneck, and the processing of glass is better, so that the casing made of glass material has begun to replace other materials.
機殼由其它材料轉換為玻璃，影響行業產能供應的不僅僅是結構件主體的生產工藝轉變那麼簡單，如何裝飾玻璃表面內容，並讓其融入到整個智慧型手機的設計語言中同樣十分重要，要在玻璃表面上進行裝飾圖案處理難度很高一直是行業的共識，更何況現在行業中需要解決的，是工藝難度更高的３Ｄ玻璃曲面印刷工藝，也因此蓋板加工廠的３Ｄ玻璃曲面印刷工藝成熟程度及產能效率，即成為相關廠商重點關注的項目之一。The casing is converted from other materials to glass, which affects the production capacity of the industry. It is not only the transformation of the production process of the structural parts. It is also very important to decorate the surface of the glass and integrate it into the design language of the entire smart phone. It is always the consensus of the industry to carry out decorative pattern processing on the glass surface. What's more, what needs to be solved in the industry is the 3D glass surface printing process with higher process difficulty, and therefore the 3D glass surface printing of the cover processing factory. Process maturity and capacity efficiency have become one of the key projects of relevant manufacturers.
其中，於該３Ｄ玻璃曲面利用印刷進行表面處理的方式，由於印刷一般係應用於平面物體的表面處理，使得當將印刷應用於３Ｄ玻璃曲面的表面處理，即需要經過多次套印，不僅花費時間長，且因搭接縫的不可避免，而會有影響美觀、浪費塗料之情況發生。另，雖有業者利用真空鍍膜方式對３Ｄ玻璃曲面進行表面處理；然而，真空鍍膜不僅速度慢，且其鍍膜成本高，加上鍍膜的膜厚較厚，會於一定程度上影響了手機的散熱，使得真空鍍膜同樣無法應用在３Ｄ玻璃曲面的大量生產。Wherein, the 3D glass curved surface is surface-treated by printing, since printing is generally applied to the surface treatment of a planar object, so that when the printing is applied to the surface treatment of the 3D glass curved surface, it is necessary to undergo multiple overprinting, which takes time Long, and because of the inevitable lap seam, it will affect the appearance and waste of paint. In addition, although some manufacturers use vacuum coating to surface treatment of 3D glass curved surface; however, vacuum coating is not only slow, and its coating cost is high, and the thick film thickness of the coating will affect the heat dissipation of the mobile phone to some extent. Therefore, vacuum coating is also not applicable to mass production of 3D glass curved surfaces.
