201039996 六、發明說明： 【發明所屬之技術領域】 本發明涉及到一種脆性材料包括玻璃、陶瓷、矽片和 半導體的切斷和裂斷刀輪及其加工方法，特別是一種用於 玻璃切割的刀輪及其加工方法。 【先前技術】 隨著科技水平的迅猛發展，許多領域要求脆性材料的 厚度薄，硬度A，且對於脆性材料的切割質量要求也越來 ° @高’尤其是玻璃行業，下面就以玻璃材料爲例來進行說 明。 ° 用來進行玻璃切割的盤狀刀輪具有的共同特徵是··均 包括切割刃部、刀輪盤面和刀輪中心用來安裝刀轴的轴孔 。其中切割刃部呈v型，便於切入玻璃，刀輪材料主要是 金剛石、聚晶或多晶金剛石、硬質合金材料，或者這幾種 材料的複合材料。 目前玻璃’尤其是液晶顯示器所用玻璃的厚度從2mm # 〇.linm越來越薄，硬度越來越大，同時對玻璃裂斷面的 質量要求也更高，使得切割時的壓力、切入技術、裂斷效 率等要求以及精度要求也都更高，給切割工具〜—刀輪的 研究開發提出了很大的挑戰。 ^ 中國大陸專利申請號ZL01124992 7和中國大陸授權公 告號CN2_8_3956.G，以及本中請人申請的中國大陸專 利授權公告號CN1323817G等提出了幾種在切_部加:的 微結構’具體參見圖6(a)_⑷、圖8(a)_⑷和圖9 201039996 (a) _ (f)所示。這幾種微結構都分別使切割刀部產生 期性的凹凸槽，其中把刀輪豎直放置在水平面時’能看到 刀輪盤面的爲正視。各圖中的分圖⑷分別爲正視圖，（b )分別爲正視圖㈣刀部的局部放大圖，⑴爲刀輪的側視 圖:（0圖爲側視圖刃部的局部放大。切割脆性材料的原 理疋.在切割時給刀輪施加一定壓力，使刃部凸起的部分 切入玻璃内部，而凹陷部分不能夠切入玻璃内部，則形成 了間斷的周期性切痕。相鄰切痕在應力作用下可以産生裂 紋，並由裂紋相連接，使得玻璃被切開並裂斷。 對於第-種結構的刀輪，如圖6(a) _(d)所示，刀 輪刃部是圓弧以及類似圓弧的凹陷61結構和凸起Μ結構 。但疋造種結構主要是針對解決切割中的滑刀造成的切割 問題。圖中所示的部位63不能形成刃口，在進行玻璃切割 時會無規則地擠壓玻璃，使玻璃産生多向的應力，並最終 造成如7(〇所示的放射狀裂紋，如圖7(a)-⑴所 示’對玻璃切割造成嚴重的破壞。 對於第二種結構的刀輪，如圖8(a) _(d)所示刀 輪刃部是矩形凹陷81和矩形凸起82結構。這種結構在玻 璃切割時，矩形凹陷81會被切割時産生的玻璃微粉末填充 ’造成堵塞，導致切割出現切入不順。 對於第三種結構的刀輪，如圖9 (a) _ (f)所示，刀輪 刃部是梯形凹陷91和倒梯形凸起92結構，而且從俯視圖 可以看到這種梯形凹陷91和倒梯形凸起92形成一個銳角 r。與第二種結構刀輪相似，這種結構在玻璃切割時梯 201039996 形凹陷91也會被切割時産生的玻璃微粉末填充，造成堵塞 〇 對於刀輪的加工方法，本申請人申請的中國大陸專利 授權公告號CN1323817C和另外的一個中國大陸專利授權公 告號CN200680003956.0中提出的用鐳射加工的方法，雷射 光束的方向相對於刀輪盤面是垂直的。在刀輪外邊緣棱線 部位加工微結構時，雷射光束必須貫穿材料或者說切斷材 料才能形成微結構，而中國大陸專利授權公告號 CN200680003956.0中提出的雷射光束相對於刀輪盤面的運 行軌迹是一個閉合或者不閉合的曲線，鐳射加工時必須把 包含在曲線内的刀輪材料整個切除下來，達到與原刀輪分 離的㈣。此彳法不能夠在材料上去除一個具有—定深度 的區域。 另外刀輪進行工作時，固定刀輪的刀架與刀輪盤面以 及刀軸與刀輪軸孔之間會高速摩擦*需要潤滑，使用液態 '間'月劑會造成玻璃污染，所以刀輪潤滑也是急需解決的問 題。 針對上述每些問題，本發明提供一種既能夠避免出現 上述=放射狀裂紋’又不會造成堵塞，使用壽命長且切割 Π»的用於切割玻璃以及其他脆性材料的刀輪及其加工 方法。 【發明内容】 本發明的一伽a ΑΑ β # vu· 個目的疋知供一種切割脆性材料的刀輪， 特別是能夠高質I + 買置切割玻璃、且提高使用壽命的刀輪。 201039996 性材：：實現上述目的’採用以下技術方案：-種切割脆 性材科的刀輪，包括由第—曲面脆 ^ ^ ^ 第一曲面以及外邊緣棱 =的角度爲第一的V形切割刃部、圓形盤 形切_料外邊緣料1具有交替分佈的切 二°凹陷結構，每個所述的切割刀包括第一曲面和第二 :面：局部以及第一侧面、第二側面、第三侧面和第四側 面，第-曲面局部和第二曲面局部的相交線爲第一段，第 側面和第二側面的相交線爲第二段，第三側面和第四側 面的相交線爲第三段，纟中第一曲面局部、第二曲面局部 和它們的相交線第一段形成V形刀口 _，第一側面第二 側面和交線第二段形成刃…第三側面、第四侧面和交 線第三段形成刃口三。 根據本發明，所述切割刀中的所述v形刃口一的夾角 爲第一角^ ’第一角^的角度範圍爲7〇度_17〇度，所述 刃口一的夾角爲第二角02’第二角必2的角度範圍爲度 至330度，所述刃口三的夾角爲第三角03，第三角必3的角 度範圍也胃30度至330 第—段的長度範圍爲弓跡 2000um，第二段的長度範圍爲〇.5um_3〇〇um，第三段的長 度範圍也爲〇.5um-3〇〇um。 根據本發明，所述的切割刃的第一〜第四側面可以是任 意面。 根據本發明，所遂交替分佈的切割刃的外形和角产可 以相同也可以不同。 根據本發明，所述的凹陷結構的底部可以是任意面， 201039996 可以疋凹陷的或者是凸起的。 根據本發明，所述的凹陷結構的底部也可以是由第一 底面和第二底面構成的角度爲第四角04的刀口四，其中刃 四的第一底面和第二底面的相交線爲第四段，第四角必* 、角又範圍爲1度至359度，棱線第四段的長度範圍爲 3um-2〇〇〇um。 根據本發明，相鄰兩個所述的切割刃之間的四個侧面 也疋一個凹陷結構的側面，所述的凹陷結構是具有此四個 侧面的任意形狀的凹陷。 根據本發明，所述的凹陷結構在遠離棱線第一段的部 位處可以具有第五側面，也可以是第一底面、第二底面和 第一曲面、第二曲面的任意過渡。 根據本發明’所述切割刃和所述凹陷結構的數目範圍 爲30-3600個’相鄰切割刀或凹陷結構相對於刀輪盤面中心 的夾角召的角度範圍爲0.1度-12度，各個相鄰切割刃或凹 陷結構所對應的夾角々的角度可以相同也可以不同。 根據本發明，所述盤面具有格線槽。 根據本發明，所述軸孔具有格線槽。 根據本發明，所述盤面和所述軸孔具有的格線槽可以 是直線線槽或者曲線線槽，可以是平行線槽或交又線槽。 根據本發明，所述格線槽中每條線槽的寬度範圍爲 lum-800\im，深度範圍爲hin-300vim ’相鄰線槽的間隔範圍 爲 20um-800um。 根據本發明’所述刀輪爲盤狀的’直徑範圍爲1mm- 201039996 材料是金剛石、聚晶或多晶金剛石、硬質合金 / 5者這幾種材料的複合材料。 、 本發明的另—個目的是提供一種切 的加工方、本 ^ 4奶丨王何科的刀輪 方法，特別是能夠高質量切割玻璃、且提古伟田 命的刀輪的加工方法。 1叔円使用壽 爲了實現上述目的，採用以下技術方荦.接 性材料的刀輪^ — 孜柯万案種切割脆 ^ 、口工方法，在刀輪v形切割刃部用鐳射槁 田的方式燒蝕去除加工得到 的切割刃和凹陷結構，刀 的雷射光束方向平行於刀輪盤 驟： 匕枯如下加工步 [1] 设置需要加工的形狀，並設置掃描間距夂 [2] 將刀輪固定在工作臺上的刀軸上，# 鼾士 at $工叼刀釉上，使刀輪上方的雷 σ於刀輪盤面，並使f射光束聚焦在ν π 割刀部邊緣； “、、仕V形切 [3] 通過調整鐳射參數並控制f 述的形狀，使刃邱、惠妹 不％仃軌跡柃描上 。卩邊緣附近被雷射光束輻照部位的一定厚 又的材料被去除’加工出所述的凹陷結構； ，使=動直於二輪_ 二:！度，並重復步驟[2]和[3]得到第二個凹 杳° U兩個相鄰凹陷結構中間沒有被加工的部分成 爲實現切割脆性材料的切割刃； 一 [5]重復上述步驟得到交替分佈在切割刀部邊緣棱線U 一周的切割刃和凹陷結構。 根據本發明，還包括在刀輪盤面上加工格線槽的步驟 201039996 Π]設計格線槽的圖案、寬度和間隔，並設置掃描間距d ， [2] 將刀輪盤面平放在工作臺上’使雷射光束方向垂直 於刀輪盤面； [3] 聚焦雷射光束於刀輪盤面表面； [4] 並用鐘射掃描燒姑去除加工，得到具有格線槽的盤 面，其中格線槽的深度可以通過調整鐳射參數進行控制。 根據本發明，還包括在刀輪軸孔中加工格線槽的步驟 Π]設置具有一定寬度和一定間隔的交叉線或平行線， 並設置掃描間距d;

Description of the Invention: [Technical Field] The present invention relates to a cutting and splitting cutter wheel for a brittle material comprising glass, ceramic, bismuth and semiconductor, and a processing method thereof, in particular for glass cutting Knife wheel and its processing method. [Prior Art] With the rapid development of technology, many fields require the thickness of brittle materials to be thin, hardness A, and the cutting quality requirements for brittle materials are also increasing. @高' Especially in the glass industry, the following is based on glass materials. For example, the description will be given. ° The disc-shaped cutter wheels used for glass cutting have the common feature that they include the cutting edge, the cutter disc surface and the shaft hole of the cutter wheel center for mounting the cutter shaft. The cutting edge is v-shaped for easy cutting into the glass. The material of the cutter wheel is mainly diamond, polycrystalline or polycrystalline diamond, hard alloy material, or a composite material of these materials. At present, the thickness of the glass used in the glass display, especially the liquid crystal display, is thinner and thinner from 2mm #〇.linm, and the hardness is getting larger and larger. At the same time, the quality of the glass cracked section is also higher, so that the pressure during cutting, the cutting technique, The requirements for cracking efficiency and accuracy are also higher, which poses great challenges for the research and development of cutting tools. ^ Mainland China Patent Application No. ZL01124992 7 and China Authorized Announcement No. CN2_8_3956.G, as well as the Chinese Patent Authorization Announcement No. CN1323817G filed by the applicant, etc., proposed several kinds of microstructures in the section: 6(a)_(4), Fig. 8(a)_(4) and Fig. 9 201039996 (a) _ (f). These kinds of microstructures respectively cause the cutting blade portion to produce a concave and convex groove, wherein when the cutter wheel is placed vertically in the horizontal plane, the face of the cutter wheel can be seen as a front view. The sub-graphs (4) in each figure are respectively a front view, (b) are a partial view of the front view (four), and (1) is a side view of the cutter wheel: (0 is a partial enlargement of the side view blade. Cutting brittle material The principle is that a certain pressure is applied to the cutter wheel during cutting, so that the convex portion of the blade is cut into the interior of the glass, and the concave portion cannot be cut into the interior of the glass, and intermittent periodic cuts are formed. Cracks can be generated and connected by cracks, so that the glass is cut and broken. For the cutter wheel of the first structure, as shown in Fig. 6(a)-(d), the blade edge is a circular arc and the like. The circular recess 61 structure and the raised Μ structure. However, the 疋 疋 结构 structure is mainly for solving the cutting problem caused by the sliding knife in the cutting. The portion 63 shown in the figure cannot form a cutting edge, and there is no cutting when performing glass cutting. Squeeze the glass regularly, causing multi-directional stress on the glass, and eventually causing radial cracks as shown in Fig. 7(a)-(1), causing severe damage to the glass cut. For the second The cutter wheel of the structure, as shown in Figure 8(a) _(d) The wheel edge portion is a structure of a rectangular recess 81 and a rectangular protrusion 82. When the glass is cut, the rectangular recess 81 is filled with the glass micropowder generated during the cutting to cause clogging, resulting in a cut in the cutting. For the third structure The cutter wheel, as shown in Fig. 9 (a) _ (f), is a trapezoidal recess 91 and an inverted trapezoidal projection 92 structure, and such a trapezoidal recess 91 and an inverted trapezoidal projection 92 can be seen from a plan view. Forming an acute angle r. Similar to the second structure cutter wheel, this structure is filled with the glass micro-powder generated when the ladder 201039996-shaped depression 91 is cut during the glass cutting, causing blockage 〇 for the processing method of the cutter wheel, this application In the laser processing method proposed in the Chinese Patent Application No. CN1323817C and another Chinese Patent Authorization No. CN200680003956.0, the direction of the laser beam is perpendicular to the surface of the cutter wheel. When processing the microstructure in the edge ridge line, the laser beam must penetrate the material or cut the material to form the microstructure, and the Chinese Patent Authorization No. CN2006800 The trajectory of the laser beam proposed in 03956.0 with respect to the disk surface of the cutter wheel is a closed or non-closed curve. During laser processing, the entire cutter wheel material contained in the curve must be cut off to achieve separation from the original cutter wheel (4).
