Description

保護膜製造方法Protective film manufacturing method

本發明係關於一種製造流程，尤指一種保護膜製造方法。The invention relates to a manufacturing process, in particular to a manufacturing method of a protective film.

近年來，智慧型手機以及平板裝置等具有大螢幕的電子裝置廣為大眾使用，而用來保護螢幕的螢幕保護貼也應因應而生，現在大多以強化玻璃製成保護貼，以增加保護強度及耐磨度。In recent years, electronic devices with large screens such as smart phones and tablet devices have been widely used by the general public, and screen protectors to protect the screens have also been developed. Nowadays, most of them are made of tempered glass to increase the protection strength. And wear resistance.

一般玻璃保護貼之製造流程為：(1)將玻璃進行裁切；(2)將裁切後之玻璃進行磨邊與鑽孔；(3)進行洗片；(4)利用化學液增加玻璃韌性；(5)進行AS防汙鍍膜(Anti-Smudge Coating)。也就是說，一般玻璃保護貼本身不具有防汙效果，需要透過鍍膜方式增加防汙效果，但是鍍膜容易隨著使用時間，而逐漸失去其效果，也容易脫離玻璃，降低玻璃保護貼之使用壽命。The general manufacturing process of glass protection stickers is: (1) cutting the glass; (2) grinding and drilling the cut glass; (3) washing the film; (4) using chemical liquid to increase glass toughness ; (5) AS anti-smudge coating (Anti-Smudge Coating). In other words, the general glass protection sticker itself does not have the anti-fouling effect, and it needs to increase the anti-fouling effect through the coating method, but the coating is easy to gradually lose its effect with the use time, and it is easy to separate from the glass, reducing the service life of the glass protection sticker .

再者，為了讓使用者有更佳的視覺感受來欣賞電子裝置上所呈現之照片及影片，有廠商研發出具有曲面螢幕之電子裝置，然而當使用者欲於具有曲面螢幕之電子裝置上黏貼保護貼以保護螢幕時，常常因螢幕具有曲率的關係，而使得保護貼無法與螢幕完全地貼合，即使以全平面貼合的方式，也會在保護貼的邊緣形成白邊。Furthermore, in order to allow users to have a better visual experience to enjoy the photos and videos displayed on the electronic device, some manufacturers have developed electronic devices with curved screens. However, when users want to paste on the electronic devices with curved screens When a protective sticker is used to protect the screen, it is often due to the curvature of the screen that the protective sticker cannot be completely attached to the screen. Even if a full-plane bonding method is used, a white border will be formed on the edge of the protective sticker.

於中華民國專利第M528872及M519066號，提及利用熱壓成型製成保護貼之曲面部分，以有效與螢幕完全貼合；但由於熱壓成型是靠壓力機和模具對材料施加外力及溫度，使材料產生塑性變形或分離，從而獲得所需形狀和尺寸的成品，所以成品之精度容易受施加外力與溫度控制之影響，因而無法確保每個成品之品質與精度之一制性。In the Republic of China Patent Nos. M528872 and M519066, it is mentioned that the curved part of the protective sticker is made by hot pressing to effectively fit the screen; but because the hot pressing depends on the press and the mold to apply external force and temperature to the material, Plastic deformation or separation of materials to obtain finished products of the required shape and size. Therefore, the accuracy of the finished product is easily affected by the application of external force and temperature control, so it is impossible to ensure the quality and accuracy of each finished product.
