Description
本創作係與導光板加工設備相關，尤其是一種導光板拋銑刀具。This creation is related to light guide plate processing equipment, especially a light guide plate polishing and milling tool.
於導光板製程中，當導光板經過各項生產步驟而形成所需結構型態後，在最終的包裝出貨前，一般來說還須經過拋銑加工，使整體尺寸進規，以利後續面板廠組裝。In the light guide plate manufacturing process, after the light guide plate has undergone various production steps to form the required structure, before the final packaging and shipment, generally it must be polished and milled to make the overall size into the gauge for subsequent follow-up Panel factory assembly.
拋銑加工中，大致可分為三道製程，分別為筒刀、盤刀與成型刀，筒刀係供以針對大型工件進行側銑、粗銑加工，盤刀則是主要用以拋銑工件平面，以獲得所需之表面粗糙度，成型刀則是用以將工件拋銑形成所需之型態，例如導角或定位角。In polishing and milling, it can be roughly divided into three processes, which are barrel cutters, disc cutters and forming cutters. The barrel cutters are used for side milling and rough milling of large workpieces, and the disc cutters are mainly used for milling workpieces. Plane to obtain the required surface roughness, and the forming cutter is used to polish and mill the workpiece into the required shape, such as lead angle or positioning angle.
然而，考量加工效率與速度，一般來說導光板之拋銑會以整組方式進行，而非逐一針對各導光板進行加工。如此，在該種拋銑加工方式下，會導致整組導光板於進行加工後有尺寸差異產生，且加工時之排屑亦為須克服之問題，以免影響後續導光板之包裝出貨品質。However, considering the processing efficiency and speed, generally speaking, the polishing and milling of the light guide plate will be carried out in a whole group, rather than processing each light guide plate one by one. In this way, in this polishing and milling processing method, the entire group of light guide plates will have size differences after processing, and chip removal during processing is also a problem to be overcome, so as not to affect the subsequent packaging and shipping quality of the light guide plates.
有鑑於此，本創作人係集結從事相關行業多年之豐富經驗，係構思並提出一種導光板拋銑刀具，以提供適用於導光板組拋銑加工之設備工具，同時消除會影響導光板品質之各項不良情況。In view of this, the creator has gathered many years of experience in related industries, and conceived and proposed a light guide plate polishing and milling tool to provide equipment and tools suitable for the polishing and milling of the light guide plate assembly, and at the same time eliminate the impact on the quality of the light guide plate. The various undesirable conditions.
本創作之一目的，旨在提供一種導光板拋銑刀具，其係能控管整組導光板於拋銑加工時的尺寸公差，並管制側邊之粗糙度，以控制側向光學的表現，使整體製程指標值上升，同時亦能降低整體廢料率。One purpose of this creation is to provide a light guide plate polishing and milling tool, which can control the dimensional tolerance of the entire group of light guide plates during polishing and milling, and control the side roughness to control the performance of the lateral optics , So that the overall process index value increases, while also reducing the overall waste rate.
為達上述目的，本創作於一實施方式中揭露一種導光板拋銑刀具，供以針對由多片導光板堆疊之導光板組進行拋銑加工，其中導光板組之總高度為D，其特徵在於：該導光板拋銑刀具為圓形盤刀，且該導光板拋銑刀具之半徑為R，並符合
基於上述實施方式，於另一實施方式中，該導光板拋銑刀具於加工時相對導光板組水平面之入刀角度θ為10度，如此係可兼具排屑與尺寸一致性之需求。Based on the above embodiment, in another embodiment, the cutting angle θ of the light guide plate milling tool relative to the horizontal plane of the light guide plate group during processing is 10 degrees, which can meet the requirements of chip removal and dimensional consistency.
進一步地，於次一實施方式中則揭露導光板組之總高度為D為160mm，如此係可取得更好之產品加工成果。Furthermore, in the next embodiment, it is disclosed that the total height D of the light guide plate group is 160 mm, so that better product processing results can be obtained.
綜上所述，本創作之導光板拋銑刀具，係透過管控刀具大小之方式，使導光板因應拋銑加工所產生拋銑圓弧差異保持於允許範圍內，降低整批產品中各導光板之尺寸差異，提升整體製程之精度與準度能力；同時符合前述條件之刀具，亦可兼顧排屑需求，消除加工碎屑殘留之不良影響，並大幅降低廢料率，讓加工後之導光板產品工差得以縮小。進一步地，針對刀具之設計，本創作亦有提出更細部的條件限制，以教示較為優異之刀具結構特徵。To sum up, the light guide plate polishing and milling tool of this creation is through the method of controlling the size of the tool, so that the light guide plate is kept within the allowable range due to the polishing and milling arc difference caused by the polishing and milling process, and the guides in the entire batch of products are reduced. The difference in the size of the light board improves the accuracy and accuracy of the overall process. At the same time, the tool that meets the aforementioned conditions can also take into account the need for chip removal, eliminate the adverse effects of processing debris, and greatly reduce the waste rate, so that the processed light guide board Product labor gap can be reduced. Furthermore, for the design of the tool, this creation also proposes more detailed conditional restrictions to teach more excellent tool structure characteristics.
在導光板之表面拋銑加工製程中，大多係利用盤刀針對導光板表面以旋轉方式進行加工，在此製程工序中，看似為平面式加工，但實際上考量排屑需求，刀具會相對被加工表面傾斜一夾角進行作動。然而，因傾斜角度加工之緣故，導致導光板組在進行旋轉拋銑加工後，會有整組尺寸差異產生，而發生前述尺寸差異之緣由係為刀具相對導光板組中各導光板所形成之拋銑痕問題。另方面，除了入刀角度以外，刀具相對於被加工物的大小比例，也會影響排屑情況。而現有之導光板拋銑製程，無論針對大尺寸或小尺寸之導光板，皆使用相同之盤刀機具，在面對大尺寸導光板加工時，衍生出盤刀過小而導致拋銑形成之粉屑不易排除之問題。綜合上述情況，本創作人發現必需找出加工物(即盤刀)與被加工物(即導光板組)之間的理想尺寸比，才能解決上述各項缺失。有鑒於此，本創作人係透過管控刀具大小之方式，來讓傾斜角度加工所造成之拋銑圓弧痕跡差異在可允許範圍內，並兼顧排屑之順暢度，進而有效提升導光板之產品良率與一致性，改善導光板拋銑製程現存之各項缺失，以下即針對本創作所揭露之一種導光板拋銑刀具進行說明。In the surface polishing and milling process of the light guide plate, most of the processing is performed by rotating the surface of the light guide plate with a disc cutter. In this process, it seems to be planar processing, but in fact, considering the chip removal requirements, the tool will be relatively The processed surface is inclined at an angle to actuate. However, due to the oblique angle processing, after the light guide plate group is subjected to rotary polishing and milling, there will be a whole group of size differences. The reason for the aforementioned size difference is that the tool is formed relative to each light guide plate in the light guide plate group. Throw milling marks. On the other hand, in addition to the entry angle, the size ratio of the tool to the workpiece will also affect the chip removal. The existing light guide plate polishing and milling process uses the same disc cutter tool for large or small light guide plates. When facing large-size light guide plates, the disc cutter is too small to cause polishing and milling. The crumbs are not easy to eliminate. Based on the above situation, the author found that it is necessary to find the ideal size ratio between the processed object (that is, the disc cutter) and the processed object (that is, the light guide plate group) in order to solve the above-mentioned deficiencies. In view of this, the creator uses the method of controlling the size of the tool to make the difference in the arc traces of the polishing and milling caused by the inclined angle processing within the allowable range, and taking into account the smoothness of chip removal, thereby effectively improving the product of the light guide plate. Yield and consistency, improve the existing deficiencies of the light guide plate polishing and milling process, the following is an explanation of the light guide plate polishing and milling tool disclosed in this creation.
請參閱第1及2圖，其係為本創作一實施方式之導光板拋銑刀具之加工應用示意圖(一)、(二)，其中，為利於示意，圖式中之導光板拋銑刀具係為簡易示意，而省略諸如承載基座或馬達等其餘機構，並圖中所示並非實際尺寸比例，合先敘明。本創作之導光板拋銑刀具1，係供以針對由多片導光板20堆疊成落之導光板組2進行拋銑加工，其中導光板組2之總高度為D。導光板拋銑刀具1之特徵在於其係為圓形盤刀，且導光板拋銑刀具1之半徑為R，並符合
附帶一提，利用圓形盤刀加工時，若相對導光板組2水平面之入刀角度θ太小會有排屑不良之情況，而入刀角度θ太大則是會導致整落尺寸差異增加，因此本創作係提出基於適切之入刀角度θ考量，並因應所欲加工之導光板組2總高度條件，來調整圓形盤刀尺寸之方式，使符合上述關係式之導光板拋銑刀具1於應用上能獲得更好的拋銑加工結果，進而達到上述之各項優良功效。 Incidentally, when machining with a circular disc cutter, if the cutting angle θ relative to the horizontal plane of the light guide plate group 2 is too small, there will be a problem of chip evacuation. If the cutting angle θ is too large, the size difference will increase. Therefore, this creation is based on the consideration of the appropriate entry angle θ, and in accordance with the total height of the light guide plate group 2 to be processed, to adjust the size of the circular disc cutter, so that the light guide plate milling cutter conforms to the above relationship With 1 in application, better polishing and milling processing results can be obtained, and the above-mentioned excellent effects can be achieved.
本創作提出之導光板拋銑刀具1，係為依據加工條件入刀角度為θ為10±5度，導光板組總高度D為140~180mm所製成符合上述條件式之圓形盤刀，以讓導光板組2之被加工表面所產生的拋銑圓弧差異大幅縮小，促進製成之導光板產品之品質與光學品味。實際應用上，係可同時設置二組導光板拋銑刀具1，以分別對堆疊成落之導光板組2共構形成之平面進行加工，而如第1圖所示。進一步地，舉例來說，當限定導光板拋銑刀具1於加工時相對導光板組2水平面之入刀角度θ為10度，且係針對總高度D為140~180mm之導光板組2進行加工時，依據上述關係式，適用之導光板拋銑刀具1之半徑R約為40～52公分，如此以入刀角度θ為10度之條件對總高度D為140～180mm之導光板組進行加工，即可達成上述功效。或者，當限定加工條件為針對總高度D為160mm之導光板組2進行加工，而入刀角度θ為10±5度時，適用之導光板拋銑刀具1之半徑R則約為31～92cm，如此以此入刀角度條件對總高度D為160mm之導光板組2進行加工，亦可獲得上述功效。The light guide plate polishing and milling tool 1 proposed in this creation is a circular disc cutter that meets the above conditional formula made according to the processing conditions. , In order to greatly reduce the difference of the polishing and milling arc generated by the processed surface of the light guide plate group 2, and promote the quality and optical taste of the finished light guide plate product. In practical applications, two sets of light guide plate polishing and milling cutters 1 can be set at the same time to process the co-structured planes of the stacked light guide plate groups 2 respectively, as shown in Figure 1. Further, for example, when the cutting angle θ of the light guide plate milling tool 1 relative to the horizontal plane of the light guide plate group 2 during processing is limited to 10 degrees, and it is performed for the light guide plate group 2 with a total height D of 140~180mm During processing, according to the above relationship, the radius R of the applicable light guide plate milling tool 1 is about 40～52 cm, so the light guide plate group with the total height D of 140～180mm under the condition that the cutting angle θ is 10 degrees The above effects can be achieved by processing. Or, when the limited processing condition is to process the light guide plate group 2 with a total height D of 160mm, and the cutting angle θ is 10±5 degrees, the radius R of the applicable light guide plate milling tool 1 is about 31~ 92cm. In this way, the light guide plate group 2 with a total height D of 160mm can be processed under the condition of the angle of entry, and the above-mentioned effects can also be obtained.
進一步地，於此再舉一實際應用上之示例進行說明，當導光板組2之總高度D為160mm，入刀角度θ為10度時，此時適用之導光板拋銑刀具1之半徑R依據上述關係式，即可得約為46cm。換言之，當使導光板拋銑刀具1之半徑R為46cm再依據設定之入刀角度θ為10度之條件進行拋銑加工後，所得到的導光板產品，原先因為盤刀尺規而於加工時造成之拋銑痕差異，即可落於可允許之範圍內，進而大幅縮減整落導光板組2中各導光板20間的尺寸差異，相對地即可提升導光板產品之品質與良率。而在排屑方面，除了調整入刀角度θ於較適切之參數外，由於以前述關係式所製成之導光板拋銑刀具1，相對於被加工的導光板組2尺寸來說，其比例係處於較為理想之狀態，因此可解決過往因為盤刀相對於導光板組2之尺寸來說過小而導致的排屑不良問題。Further, here is another practical example for description. When the total height D of the light guide plate group 2 is 160mm, and the cutting angle θ is 10 degrees, the radius of the applicable light guide plate milling tool 1 at this time is According to the above relationship, R can be about 46cm. In other words, when the radius R of the light guide plate milling tool 1 is 46cm and then the milling process is performed according to the set entry angle θ of 10 degrees, the light guide plate product obtained is originally due to the disc cutter ruler. The difference in polishing and milling marks caused during processing can fall within the allowable range, thereby greatly reducing the size difference between the
綜上所述，本創作之導光板拋銑刀具，係以找出加工物與被加工物之理想尺寸比之概念，透過管控刀具大小使導光板因應拋銑加工所產生拋銑圓弧差異保持於允許範圍內，降低整批產品中各導光板之尺寸差異，提升整體製程之精度與準度能力；同時符合前述條件之刀具，亦可兼顧排屑需求，消除加工碎屑殘留之不良影響，並大幅降低廢料率，讓加工後之導光板產品工差得以縮小。進一步地，針對影響刀具設計之加工條件，本創作亦有提出更細部的限制，以教示出較為優異之刀具結構特徵，並使板面兩側，業界稱之腰身，的光學表現一致。In summary, the light guide plate milling tool in this creation is based on the concept of finding the ideal size ratio of the processed object to the processed object. By controlling the size of the tool, the light guide plate responds to the difference in the milling arc generated by the milling process. Keep within the allowable range, reduce the size difference of each light guide plate in the whole batch of products, and improve the accuracy and accuracy of the overall process; at the same time, the tools that meet the aforementioned conditions can also take into account the need for chip removal and eliminate the adverse effects of processing debris , And greatly reduce the waste rate, so that the work error of the processed light guide plate product can be reduced. Furthermore, in view of the processing conditions that affect the design of the tool, this creation also proposes more detailed restrictions to show the better structural characteristics of the tool, and to make the optical performance of both sides of the board, which is called the waist in the industry, the same.
