Description
例えば、本発明の権利範囲を外れることなく第1構成要素を第2構成要素ということができ、同じように第2構成要素も第1構成要素ということができる。
本出願において、「含む」または「有する」などの用語は明細書に記載された特徴、数字、ステップ、段階、動作、構成要素、部品またはこれらを組み合わせたものが存在することを意味し、一つまたはそれ以上の他の特徴や数字、ステップ、段階、動作、構成要素、部品またはこれらを組み合わせたものの存在または付加可能性を予め排除しないこととして理解されるべきである。
従って、前記初期クラック20形成の際前記強化ガラス10の縁部eが割れてしまう現象が頻繁に発生し、チップまたはパーティクルなどが発生し、強化ガラス10の切断品質に影響を及ぼすという問題点があった。
このため前記強化ガラス10の角部eの切断の際チップやパーティクルなどが発生せず、切断部位に熱的損傷が発生しない。
Claims (7)
- 強化ガラスの角部を曲線に切断する方法において、
前記強化ガラスの縁部までは延びないように、前記強化ガラスの角部の切断しようとする曲線上に位置するように前記強化ガラスの表面上に一定の深さで初期クラックを形成する段階と、
前記強化ガラスの角部の切断しようとする曲線上に沿って前記強化ガラスの表面上にレーザービームを照射して熱衝撃を発生させて既に生成された前記初期クラックを中心として前記角部の切断しようとする曲線上に沿って両側の縁部方向にクラックが伝播されて前記強化ガラスが切断される段階と、を含むことを特徴とする、
強化ガラスの曲線切断方法。 - 前記初期クラックは、前記強化ガラスの角部を二等分するセンターラインを中心に前記角部の切断しようとする曲線上に沿って対称するように前記強化ガラスの表面上に一定の深さで形成されることを特徴とする請求項1に記載の強化ガラスの曲線切断方法。
- 前記初期クラックは、前記強化ガラスの表面上に接触式に形成されることを特徴とする請求項1に記載の強化ガラスの曲線切断方法。
- 前記初期クラックは強化ガラスの表面上にホイールによって接触式に形成されることを特徴とする請求項3に記載の強化ガラスの曲線切断方法。
- 前記初期クラックは、前記強化ガラスの表面上に非接触式に形成されることを特徴とする請求項1に記載の強化ガラスの曲線切断方法。
- 前記初期クラックは強化ガラスの表面上に照射されるレーザービームによって非接触式に形成されることを特徴とする請求項5に記載の強化ガラスの曲線切断方法。
- 前記レーザービームは、前記強化ガラスの角部の切断される曲線上に沿って前記強化ガラスの表面上に少なくとも1回照射されることを特徴とする請求項1に記載の強化ガラスの曲線切断方法。
