Abstract
Description
本發明係關於一種組合式砂輪,尤其一種具有凹型研磨槽的組合式砂輪。 The invention relates to a combined grinding wheel, especially a combined grinding wheel with concave grinding grooves.
光學鏡片是一項精密的工業技術,其成品可以做為視覺輔助的眼鏡、顯微設備、天文觀測設備等,也利用於攝影鏡頭、投影機、光碟機等各式光學設備,特別是近年來行動電話搭配攝錄影功能,因鏡頭所需,使光學鏡片的用量與日俱增。 Optical lens is a sophisticated industrial technology, and its finished products can be used as visually assisted glasses, microscopic equipment, astronomical observation equipment, etc., and also used in various optical equipment such as photographic lenses, projectors, optical disk drives, especially in recent years The mobile phone is equipped with a video recording function. Due to the need of the lens, the amount of optical lenses is increasing day by day.
一個精密的鏡面是經過許多道製程而完成,切割、研磨、拋光、定芯等製造製程,之後,根據用途有的還會進行鍍膜、塗墨等製程。在定芯製程中,係以夾具夾持鏡片旋轉,使鏡片的邊緣與砂輪的研磨面接觸進行研磨,進而控制鏡片的外徑、深度、以及倒角。 A precise mirror surface is completed through many manufacturing processes, such as cutting, grinding, polishing, core setting and other manufacturing processes. Afterwards, some processes such as coating and ink coating will also be carried out according to the purpose. In the core setting process, the lens is clamped to rotate the lens, so that the edge of the lens is in contact with the grinding surface of the grinding wheel for grinding, and then the outer diameter, depth, and chamfer of the lens are controlled.
一般而言,砂輪為獨立的砥石,側邊(外沿)形成研磨凹槽,定芯製程時就是用此研磨凹槽研磨鏡片的邊緣。研磨凹槽會有兩個對向的傾斜面,是用來倒角的,研磨凹槽的底部是一個研磨平面,用於外徑的處理。 Generally speaking, the grinding wheel is an independent grindstone, and the side (outer edge) forms a grinding groove. This grinding groove is used to grind the edge of the lens during the core setting process. The grinding groove will have two opposite inclined surfaces, which are used for chamfering. The bottom of the grinding groove is a grinding plane for the treatment of the outer diameter.
研磨凹槽的研磨表面設有研磨粒子(顆粒),不同研磨粒徑大小的研磨粒子所進行的研磨效果會不同。然而,習知技術的砂輪一旦磨耗使研磨粒子脫落的話,為維持鏡片的良率,就得立刻更換整個砂輪,但有時僅 是一個小區域的過度磨耗就要整個砂輪換新,難免形成浪費而增加生產成本。 The grinding surface of the grinding groove is provided with grinding particles (particles), and the grinding effect of the grinding particles with different grinding particle sizes will be different. However, once the grinding wheels of the conventional technology are worn and the abrasive particles fall off, in order to maintain the yield of the lens, the entire grinding wheel must be replaced immediately, but sometimes only Excessive wear in a small area requires the entire grinding wheel to be renewed, which inevitably creates waste and increases production costs.
因此,本發明的主要目的在於提供一種可替換輪片的組合式砂輪。 Therefore, the main object of the present invention is to provide a combined grinding wheel with replaceable wheels.
本發明之其中一目的在提供一種利用於鏡片定芯製程之組合式砂輪,利用多個砂輪部件或砥石相互組成以周緣(外沿)形成研磨凹槽,不僅可用於鏡片的外徑、深度、以及倒角製作。理想時,當其中任一砂輪部件或砥石的研磨粒子有過度磨損時,只要更換不良的砂輪部件或砥石即可,不需整個砂輪更換而形成浪費。 One of the objects of the present invention is to provide a combined grinding wheel used in the lens centering process. A plurality of grinding wheel components or grindstones are used to form a grinding groove on the periphery (outer edge), which can be used not only for the outer diameter, depth, and depth of the lens. And chamfer production. Ideally, when the abrasive particles of any of the grinding wheel components or whetstones are excessively worn, it is sufficient to replace the bad grinding wheel components or whetstones, without replacing the entire grinding wheel and forming waste.
本發明的一觀點,在於提供一種組合式砂輪,組合式砂輪係分別由至少兩或三個砂輪部件組合而成,而各個砂輪部件得具有一研磨表面,各個砂輪部件經組合後,組合式砂輪得具有一研磨凹槽,而該凹槽得包括各砂輪部件的研磨表面之至少一部份。 One aspect of the present invention is to provide a combined grinding wheel. The combined grinding wheel is composed of at least two or three grinding wheel parts, and each grinding wheel part must have a grinding surface. After each grinding wheel part is combined, the combined grinding wheel There must be a grinding groove, and the groove must include at least a part of the grinding surface of each grinding wheel component.
再者,組合式砂輪亦得由至少兩個或三個輪型砥石組合而成,各個輪型砥石的外沿具有一研磨表面,經組合各輪型砥石後,研磨表面得大致呈一凹槽狀,而左右兩側砥石的研磨表面的至少一部份係相對於中間的輪型砥石的表面為傾斜且為相互面對的。 Furthermore, the combined grinding wheel must also be composed of at least two or three wheel-shaped grindstones. The outer edge of each wheel-shaped grindstone has a grinding surface. After the combination of the wheel-shaped grindstones, the grinding surface is roughly a groove At the same time, at least a part of the grinding surface of the left and right grindstones is inclined with respect to the surface of the wheel-shaped grindstone in the middle and faces each other.
本發明所提供一種之組合式砂輪,利用多個砂輪部件或砥石相互組成,較佳時,可用於鏡片定芯製程的外徑、深度、以及倒角製作,並且其中任一砂輪部件或砥石的研磨粒子有過度磨損時,只要更換不良的砂輪部件或砥石即可,不需整個砂輪更換而形成浪費。 The present invention provides a combined grinding wheel, which is composed of multiple grinding wheel parts or whetstones. Preferably, it can be used for the outer diameter, depth, and chamfering of the lens centering process, and any of the grinding wheel parts or whetstones When the abrasive particles are excessively worn, only the bad grinding wheel components or whetstones need to be replaced, and there is no need to replace the entire grinding wheel to cause waste.

請同時參閱圖1A以及圖1B,圖1A係本發明組合式砂輪的一實施例之分離示意圖。圖1B係本發明組合式砂輪於同一實施例之組合示意圖。通常,組合式砂輪10係由至少二個以上的砂輪部件12組合而成,而本實施例中則包括有三個砂輪部件12。於本例中,三個砂輪部件12之外緣(外沿)為具有研磨粒子之研磨表面,三個砂輪部件12彼此以側面緊鄰貼附以相互組合,結合後成為圖1B之組合式砂輪10。由圖可見,組合式砂輪10具有一研磨凹槽,而其同時包括各個砂輪部件12的至少一部份。

而當本實施例的組合式砂輪10應用在製造鏡片之定芯製程中時,砂輪部件12接合後的研磨面會呈現一凹狀,亦即為研磨凹槽14。研磨凹槽14可用於進行鏡片的外徑、深度、以及倒角製作。為了使接合後的研磨凹
槽14精準,所以如圖1A中可見砂輪部件12上有定位子16,與另一個砂輪部件12的定位孔18配合,可以使多個砂輪部件12以正確的位置相互組合。
When the combined
補充說明的是,關於三個砂輪部件12的研磨面中研磨粒子(例如是鑽粒)之研磨粒度,可以採用相同粒徑的研磨粒子也可以分別採用不同粒徑的研磨粒子,而通常來說,研磨凹槽兩側的斜向研磨面中包括的研磨粒子的粒徑係較研磨凹槽中間相對平坦處的研磨粒子的粒徑來得小,亦即其粒度編號較大。另外,為符合精密的鏡片定芯製程所需,研磨粒子粒徑大小在小於210μm,亦即約當大於#100號的研磨粒子的粒度,時其效果較佳。而當大於#200號研磨粒子的粒度時,其效果更佳。而當研磨粒子的粒徑愈小,其研磨期間損害工件的機會相對愈低,但研磨效率亦相對較差,故研磨粒子的粒徑不宜過小。

補充說明的是,通常研磨倒角所需傾斜的研磨面3002、3202轉向研磨外徑之第三研磨面3402的轉折處為結構最易損壞之處,所以本實施例將轉折處設計在第一砂輪部件30與第二砂輪部件32研磨面的中段而非兩部件(30與34、32與34)的銜接處,可強化此部分的結構強度。

補充說明的是,通常研磨倒角所需的傾斜研磨面5002、5402轉向研磨外徑之研磨平面5202的轉折處為結構最易損壞之處,所以本實施例將轉折處設計在第一輪型砥石50與第三輪型砥石54研磨面的中段而非兩部件(50與52、52與54)的銜接處,可強化此部分的結構強度。

第一輪型砥石50、第二輪型砥石52、以及第三輪型砥石54之研磨面中研磨粒子之研磨粒度,可以是相同粒徑大小的研磨粒子,也可以採用不同粒徑大小的研磨粒子,為符合精密的鏡片定芯製程所需,研磨面中的研磨粒子之粒徑大小係以小於210μm為佳,相當於#100的研磨粒度為佳,由此範圍粒徑大小之研磨粒子相互組合為佳,而增加砥石粒度大小的選擇,甚至選擇不同硬度之研磨粒子,有助於縮短加工時間,且同步提升良率。
