參照圖面而說明本發明之一實施型態。首先，參照圖1，說明成為加工之對象的積層體10。圖1中，Z方向為厚度方向，X方向及Y方向為垂直於Z方向之方向。 An embodiment of the present invention will be described with reference to the drawings. First, referring to FIG. 1, the laminated body 10 to be processed will be described. In Figure 1, the Z direction is the thickness direction, and the X and Y directions are directions perpendicular to the Z direction.

積層體10係具有複數之光學膜12。各光學膜12係可為單層膜，亦可為積層膜。 The laminated body 10 has a plurality of optical films 12. Each optical film 12 system may be a single-layer film or a multilayer film.

單層膜之例係樹脂膜。樹脂之例係纖維素系樹脂(三乙醯基纖維素等)、聚烯烴系樹脂(聚丙烯系樹脂等)、環狀烯烴系樹脂(降莰烯系樹脂等)、丙烯酸系樹脂(聚甲基丙烯酸甲酯系樹脂等)、聚酯系樹脂(聚對苯二 甲酸乙二酯系樹脂等)、及、聚醯亞胺系樹脂(聚醯亞胺、聚醯胺醯亞胺)等。此等之單層膜係可為保護膜、基材膜、相位差膜、窗口膜(window film)等之光學膜。 An example of a single-layer film is a resin film. Examples of resins are cellulose resins (triacetyl cellulose, etc.), polyolefin resins (polypropylene resins, etc.), cyclic olefin resins (norbornene resins, etc.), acrylic resins (polymethyl Methyl acrylate-based resins, etc.), polyester-based resins (polyterephthalene Ethylene formate-based resins, etc.), and polyimide-based resins (polyimine, polyimide), and the like. These single-layer films can be optical films such as protective films, base films, retardation films, and window films.

積層膜係具有複數之層的膜。積層膜之例係偏光膜、圓偏光板、及觸控感測器。 The laminated film is a film having a plurality of layers. Examples of laminated films are polarizing films, circular polarizing plates, and touch sensors.

例如，偏光膜係至少具備基材、及偏光片。 For example, the polarizing film system includes at least a substrate and a polarizer.

圓偏光板係例如，具有偏光片、及相位差(1/4 λ)膜。 The circular polarizing plate has, for example, a polarizer and a retardation (1/4 λ) film.

觸控感測器係可包含透明基板、感知圖型層、及感測線。 The touch sensor system may include a transparent substrate, a sensing pattern layer, and a sensing line.

積層膜係可更具備黏著劑層、接著劑層、剝離膜、保護膜等之層。 The laminated film can be further provided with layers such as an adhesive layer, an adhesive layer, a release film, and a protective film.

至少一個之積層膜典型上，係具有一或複數之黏著劑層。所謂黏著劑係具有黏著性而可直接在室溫與其他之構件貼合的層。黏著劑之例係丙烯酸系黏著劑、聚矽氧系黏著劑、胺基甲酸酯系黏著劑。在積層體加工裝置中進行加工之時點中，積層體10中之黏著劑層係具有黏著性。 At least one laminated film typically has one or more adhesive layers. The so-called adhesive is a layer that has adhesiveness and can be directly attached to other components at room temperature. Examples of adhesives are acrylic adhesives, silicone adhesives, and urethane adhesives. At the time of processing in the laminated body processing apparatus, the adhesive layer in the laminated body 10 has adhesiveness.

本發明中之黏著劑層係可列舉可藉由熱或光等進行交聯硬化者。 Examples of the adhesive layer in the present invention include those that can be cross-linked and hardened by heat, light, or the like.

該黏著劑層係在硬化前具有黏著性而可在室溫下與其他之構件貼合，再者，若藉由熱或光等之方法進行交聯而硬化則接著強度會提高之黏著劑層。如此之黏著劑之例係丙烯酸系黏接著劑。又，在積層體加工裝置中進行加工之時點中，積層體10中之黏著劑係硬化前且具有黏著性。 The adhesive layer is adhesive before curing and can be bonded to other components at room temperature. Moreover, if it is cured by heat or light, the adhesive layer will increase the adhesive strength. . An example of such an adhesive is an acrylic adhesive. In addition, at the time of processing in the laminated body processing device, the adhesive in the laminated body 10 has adhesiveness before being hardened.

若積層體10包含黏著劑層，因黏著劑層之碎屑等容易附著於刀刃，故本發明之效果高。 If the layered body 10 includes an adhesive layer, since the scraps of the adhesive layer and the like easily adhere to the blade, the effect of the present invention is high.

各光學膜12之厚度並無特別限定，但例如，為20μm至500mm，較佳係50μm至500μm，更佳係可設為50μm至200μm。 The thickness of each optical film 12 is not particularly limited, but for example, it is 20 μm to 500 mm, preferably 50 μm to 500 μm, and more preferably 50 μm to 200 μm.

積層膜包含黏著劑層時，各黏著劑層之厚度係可設為50μm以上，亦可為100μm以上。各黏著劑層之厚度係亦可為250μm以下。 When the laminated film includes an adhesive layer, the thickness of each adhesive layer may be 50 μm or more, or 100 μm or more. The thickness of each adhesive layer may also be 250 μm or less.

如上述，積層體10係具備複數之如此的光學膜12，在積層體10中之光學膜12的數若為2以上則無特別限定，但通常為5以上，可為10以上，亦可為50以上。積層體10之各光學膜12通常係具有互相相同之積層構造的光學膜12，但亦可積層具有互相相異之積層構造的光學膜12。 As described above, the laminated body 10 is provided with a plurality of such optical films 12. The number of optical films 12 in the laminated body 10 is not particularly limited if it is 2 or more, but it is usually 5 or more, may be 10 or more, or may be above 50. The optical films 12 of the laminated body 10 are usually optical films 12 having the same laminated structure, but optical films 12 having mutually different laminated structures may be laminated.

又，積層體10之厚度例如為10mm至60mm，較佳係可設為20mm至50mm。 In addition, the thickness of the layered body 10 is, for example, 10 mm to 60 mm, preferably 20 mm to 50 mm.

佔有積層體10之厚度的黏著劑層之合計厚度的比率係可為30%以上，亦可為40%以上。若黏著劑層之合計厚度變厚，因更容易附著於刀刃，故效果高。 The ratio of the total thickness of the adhesive layer occupying the thickness of the layered body 10 may be 30% or more, or 40% or more. If the total thickness of the adhesive layer becomes thicker, it is easier to adhere to the blade, so the effect is high.

積層體10係將積層體10固定於積層體加工裝置100之一對接觸構件22之間(詳細內容係後述)時，為防止光學膜12刮傷，除了複數之光學膜12以外，可在積層方向之兩端的一者或兩者具有保護膜14。 When the laminated body 10 is fixed between one pair of contact members 22 of the laminated body processing apparatus 100 (details are described later), in order to prevent the optical film 12 from being scratched, in addition to the plural optical films 12, it can be laminated One or both of the two ends of the direction have protective films 14.

保護膜14之例為樹脂膜。樹脂之例係除了上述之樹脂膜所例示的樹脂以外，尚為聚苯乙烯、聚對苯二甲酸乙二酯等。 An example of the protective film 14 is a resin film. Examples of resins are polystyrene, polyethylene terephthalate, etc. in addition to the resins exemplified in the above-mentioned resin film.

保護膜14之厚度係例如，可設為0.2mm至1.0mm，較佳係可設為0.3mm至0.8mm，更佳係可設為0.3mm至0.6mm。 The thickness of the protective film 14 can be, for example, 0.2 mm to 1.0 mm, preferably 0.3 mm to 0.8 mm, and more preferably 0.3 mm to 0.6 mm.

光學膜12之外形形狀(從厚度方向觀看之形狀)並無特別限定。圖2係從厚度方向(Z方向)觀看積層體10之各種的例之圖。積層體10之外 形形狀係分別如圖2之(a)至(e)所示，可為矩形、圓角之矩形、具有凹部PD之形態、具有凸部PP之形態、具有孔洞部TH之形態。在此，非直線部之例係帶有圓形之部分R。 The outer shape of the optical film 12 (the shape viewed from the thickness direction) is not particularly limited. FIG. 2 is a diagram showing various examples of the laminate 10 viewed from the thickness direction (Z direction). Laminated body 10 outside The shapes are as shown in (a) to (e) of FIG. 2, and can be rectangles, rectangles with rounded corners, shapes with recesses PD, shapes with protrusions PP, and shapes with holes TH. Here, an example of a non-linear part is a part R with a circular shape.

在一積層體10中之各光學膜12的外形形狀通常為實質上相同。 The outer shape of each optical film 12 in a laminated body 10 is generally substantially the same.

例如，藉由從膜胚以湯姆森刀(Thomson)等切出各光學膜12，可獲得具有實質上相同之外形形狀的多數之光學膜12。積層體10中，各光學膜12係如圖2所示，以外形形狀成為相同方向之方式積層，如圖1所示，藉由各光學膜12之外側的端面，形成積層體10之外側的端面EF。又，如圖2之(e)所示，各光學膜12具有孔洞部TH時，在圖1以點線所示，除了外側之端面EF以外，在孔洞部TH內亦形成內側之端面EF。 For example, by cutting out each optical film 12 from a film embryo with a Thomson knife or the like, a plurality of optical films 12 having substantially the same outer shape can be obtained. In the laminated body 10, the optical films 12 are laminated so that the outer shape becomes the same direction as shown in FIG. 2. As shown in FIG.端面EF. Furthermore, as shown in FIG. 2(e), when each optical film 12 has a hole portion TH, as shown by a dotted line in FIG. 1, in addition to the outer end surface EF, an inner end surface EF is also formed in the hole portion TH.

各光學膜12之大小並無特別限定，例如，膜之一邊的長度係例如可為100mm以上。 The size of each optical film 12 is not particularly limited. For example, the length of one side of the film may be, for example, 100 mm or more.

接著，說明加工該積層體10之積層體加工裝置100的一例。圖3係本實施型態之積層體加工裝置100的側面圖。 Next, an example of the laminated body processing apparatus 100 for processing the laminated body 10 will be described. FIG. 3 is a side view of the laminated body processing apparatus 100 of this embodiment.

本實施型態之積層體加工裝置100係具有固定積層體10之固定機構20及加工部40。 The laminated body processing apparatus 100 of this embodiment has a fixing mechanism 20 for fixing the laminated body 10 and a processing part 40.

固定機構20係以將積層體10從積層方向之兩側夾持並固定之方式所構成。具體而言，固定機構20主要係具備一對接觸構件22、固定部61、及押壓部60。 The fixing mechanism 20 is configured to clamp and fix the layered body 10 from both sides in the layering direction. Specifically, the fixing mechanism 20 mainly includes a pair of contact members 22, a fixing portion 61, and a pressing portion 60.

一對接觸構件22係分別為板狀構件，且其厚度方向配置於Z方向(進行押壓之方向及積層體之厚度方向)，並以從厚度方向之兩側夾持膜之積 層體10的方式朝上下方向離開而配置。圖3中，X、Y方向為水平方向，且Z方向為垂直方向。 The pair of contact members 22 are plate-shaped members, and their thickness directions are arranged in the Z direction (the direction of pressing and the thickness direction of the laminate), and the film is sandwiched from both sides of the thickness direction. The layer body 10 is arranged so as to be separated from each other in the vertical direction. In Figure 3, the X and Y directions are horizontal, and the Z direction is the vertical direction.

從Z方向觀看接觸構件22之大小係可在小於被固定之膜的積層體10的表面(與厚度方向垂直的面)的外形形狀之範圍適當設定。 The size of the contact member 22 viewed from the Z direction can be appropriately set in a range smaller than the outer shape of the surface (a surface perpendicular to the thickness direction) of the laminated body 10 of the film to be fixed.

如圖3所示，在加工前將積層體10以一對接觸構件22夾持時，積層體10之外側的端面EF從接觸構件22之端面AP突出的突出量T係以0.8mm至1.5mm為佳。例如，加工前之突出量T係可設為1mm。加工後之積層體的突出量T係可設為0.3至0.8mm，並可設為0.5mm。 As shown in FIG. 3, when the laminated body 10 is clamped by a pair of contact members 22 before processing, the protrusion amount T of the end face EF of the outer side of the laminated body 10 from the end face AP of the contact member 22 is 0.8 mm to 1.5 mm Better. For example, the protrusion amount T before processing can be set to 1mm. The protrusion amount T of the laminated body after processing can be set to 0.3 to 0.8 mm, and can be set to 0.5 mm.

接觸構件22係分別以金屬構件為佳。金屬之例係鋁、鋼、不銹鋼、合金工具鋼(例如SKD11)等。 The contact members 22 are preferably metal members. Examples of metals include aluminum, steel, stainless steel, alloy tool steel (such as SKD11), and the like.

下方之接觸構件22係隔著連結部24而固定於固定部61，且上方之接觸構件22係隔著連結部24而固定於押壓部60。 The lower contact member 22 is fixed to the fixing portion 61 via the connecting portion 24, and the upper contact member 22 is fixed to the pressing portion 60 via the connecting portion 24.

押壓部60係配置於比固定部61更上方，且押壓部60係構成為相對於固定部61可使上方之接觸構件22朝上下方向移動。因此，押壓部60係可使上方之接觸構件22朝向下方之接觸構件22進行押壓。亦即，可在一對接觸構件22之間將積層體10從厚度方向之兩側進行押壓並固定。 The pressing part 60 is arranged above the fixed part 61, and the pressing part 60 is configured to be able to move the upper contact member 22 in the vertical direction with respect to the fixed part 61. Therefore, the pressing portion 60 can press the upper contact member 22 toward the lower contact member 22. That is, the laminated body 10 can be pressed and fixed between the pair of contact members 22 from both sides in the thickness direction.

押壓部60之具體的構成並無特別限定，例如，可使用螺旋千斤頂、油壓千斤頂等習知之移動機構。可為一軸式，亦可為多軸式。 The specific structure of the pressing portion 60 is not particularly limited. For example, conventional moving mechanisms such as screw jacks and hydraulic jacks can be used. It can be a single-axis type or a multi-axis type.

加工部40係具有：端銑刀(具有刀刃之工具)44、使端銑刀旋轉之旋轉部42、使進行旋轉之端銑刀44相對於積層體相對地移動之移動部46、及噴射乾冰粒子之噴嘴420。 The processing part 40 has: an end mill (a tool with a cutting edge) 44, a rotating part 42 for rotating the end mill, a moving part 46 for moving the rotating end mill 44 relative to the laminated body, and spraying dry ice Nozzle 420 of particles.

端銑刀44之形態並無特別限定，但通常如圖3所示，具備：具有刀刃部44b及柄(shank)部44a且朝旋轉之軸方向延伸的柱狀部44z、及設在刀刃部44b之外表面的刀刃44c。就端銑刀44而言，例如，較佳可使用Router型之端銑刀等。端銑刀44之刀刃部44b的長度(Z軸方向)係以比積層體10之厚度更長為佳。端銑刀之刀刃部44b係在外周面具有刀刃44c，但在前端44t亦可具有刀刃。 The form of the end mill 44 is not particularly limited, but usually as shown in FIG. 3, it has: a cylindrical portion 44z having a blade portion 44b and a shank portion 44a and extending in the direction of the axis of rotation, and provided on the blade portion The blade 44c on the outer surface of 44b. As for the end mill 44, for example, a router-type end mill or the like can be preferably used. The length (in the Z-axis direction) of the blade portion 44b of the end mill 44 is preferably longer than the thickness of the laminated body 10. The cutting edge part 44b of the end mill has a cutting edge 44c on the outer peripheral surface, but it may have a cutting edge at the front end 44t.

旋轉部42係使端銑刀44繞其軸周圍旋轉。在本實施型態，旋轉部42係使端銑刀44繞與積層體10之厚度方向(Z方向)平行的軸周圍旋轉。 The rotating part 42 rotates the end mill 44 around its axis. In this embodiment, the rotating part 42 rotates the end mill 44 around an axis parallel to the thickness direction (Z direction) of the laminated body 10.

移動部46係以端銑刀44之刀刃部44b之外周面接觸積層體10之端面EF的狀態，使進行旋轉之端銑刀44沿著端面EF，而朝與積層體10之厚度方向垂直的方向移動。移動部46之例係3軸(XYZ)驅動裝置或機械手臂。 The moving portion 46 is in a state where the outer peripheral surface of the blade portion 44b of the end mill 44 is in contact with the end surface EF of the laminated body 10, so that the rotating end mill 44 is directed along the end surface EF and perpendicular to the thickness direction of the laminated body 10. Move in direction. Examples of the moving part 46 are a three-axis (XYZ) drive device or a robot arm.

在此，移動部46係可使端銑刀44相對於端銑刀之旋轉朝上切之方向移動，亦可朝下切之方向移動。 Here, the moving part 46 can move the end mill 44 in the upward cutting direction relative to the rotation of the end mill, and can also move in the downward cutting direction.

圖4之(a)及(b)係表示使進行旋轉之端銑刀44接觸積層體10同時並使其移動之狀態的圖，係從柄部44a側(從上方朝向下方)觀看圖3之積層體10及刀刃部44b之水平剖面的圖。刀刃部44b係朝箭號D1之方向旋轉，刀刃部44b係沿著端面EF，而相對於積層體10相對地朝箭號D2之方向移動。 Fig. 4 (a) and (b) are diagrams showing the state where the rotating end mill 44 is brought into contact with the laminated body 10 and moved at the same time, and is viewed from the side of the shank 44a (from above to below). A horizontal cross-sectional view of the laminated body 10 and the blade portion 44b. The blade portion 44b rotates in the direction of the arrow D1, and the blade portion 44b moves in the direction of the arrow D2 relative to the laminated body 10 along the end face EF.

圖4之(a)係表示端銑刀44朝上切方向移動之狀況的水平剖面圖。刀刃44c於點P接觸積層體10時之刀刃44c行進之方向、與端銑刀44之移動方向D2為相同的方向時，稱為端銑刀44朝上切之方向進行移動。相對於此，圖4之(b)係表示端銑刀44朝下切方向移動之狀況的水平剖面圖。刀刃 44c於點P從積層體10離開時之刀刃44c行進之方向、與端銑刀44之移動方向D2為相反方向時，稱為端銑刀44朝下切之方向移動。 Fig. 4(a) is a horizontal sectional view showing the state where the end mill 44 moves in the upward cutting direction. When the cutting edge 44c moves in the same direction as the moving direction D2 of the end mill 44 when the point P contacts the laminated body 10, the end mill 44 is referred to as moving in the upward cutting direction. In contrast, Fig. 4(b) is a horizontal cross-sectional view showing the state where the end mill 44 moves in the downward cutting direction. Blade When the direction of travel of the blade 44c when the point P is separated from the laminated body 10 and the moving direction D2 of the end mill 44 are opposite to the moving direction D2 of the end mill 44, the end mill 44 is referred to as the downward cutting direction of the end mill 44.

移動部46係從抑制加工後之積層體10的端面之碎屑的附著之觀點而言，較佳係使端銑刀44相對於端銑刀44之旋轉朝上切之方向移動。 The moving part 46 preferably moves the end mill 44 in the upward cutting direction relative to the rotation of the end mill 44 from the viewpoint of suppressing the adhesion of debris on the end surface of the laminated body 10 after processing.

如圖3所示，噴嘴420係連接後述之乾冰粒子供給部300，並可噴射乾冰粒子。 As shown in FIG. 3, the nozzle 420 is connected to the dry ice particle supply unit 300 described later, and can spray dry ice particles.

噴嘴420係藉由連結部424而固定於移動部46。又，噴嘴420之軸線，亦即乾冰粒子之噴射方向EJ係朝向端銑刀44之刀刃部44b。因此，在端銑刀44移動時，噴嘴420之噴射方向EJ係朝向端銑刀44之刀刃部44b，可連續去除切削時之附著於刀刃部44b的碎屑。噴嘴420之開口為圓形。噴嘴420之開口的直徑係可設為1至10mm。 The nozzle 420 is fixed to the moving part 46 by the connecting part 424. In addition, the axis of the nozzle 420, that is, the spraying direction EJ of the dry ice particles, is toward the blade portion 44b of the end mill 44. Therefore, when the end mill 44 moves, the spray direction EJ of the nozzle 420 is directed to the edge portion 44b of the end mill 44, so that the debris attached to the edge portion 44b during cutting can be continuously removed. The opening of the nozzle 420 is circular. The diameter of the opening of the nozzle 420 can be set to 1 to 10 mm.

接著，參照圖5，詳細說明噴嘴420之軸方向，亦即來自噴嘴420之乾冰粒子的噴射方向EJ。 Next, referring to FIG. 5, the axial direction of the nozzle 420, that is, the spray direction EJ of the dry ice particles from the nozzle 420, will be described in detail.

具體而言，噴射方向EJ較佳係朝與端銑刀44之加工碎屑的排出方向為相反方向，且與端銑刀之柱狀部44z之軸為斜向地配置。 Specifically, the ejection direction EJ is preferably the opposite direction to the discharge direction of the machining chips of the end mill 44 and is arranged obliquely to the axis of the columnar portion 44z of the end mill.

例如，如圖5之(a)所示，端銑刀為右刀刃右螺旋，亦即，從柄部44a側觀看時刀刃44c以順時鐘方向從柄部44a朝向刀刃部44b之前端的方式形成螺旋狀，且脫離面44d比刀刃44c設於刀刃部44b之更前端側時，端銑刀44係從柄部44a觀看時朝順時鐘方向旋轉，加工碎屑排出方向係從刀刃部44b之前端朝向柄部44a之方向。 For example, as shown in Figure 5(a), the end mill is a right-handed spiral, that is, when viewed from the side of the shank 44a, the blade 44c forms a spiral in a clockwise direction from the shank 44a to the front end of the blade 44b When the detachment surface 44d is provided on the front end side of the blade portion 44b than the blade 44c, the end mill 44 rotates clockwise when viewed from the shank 44a, and the processing chip discharge direction is from the front end of the blade portion 44b. The direction of the handle 44a.

如圖5之(b)所示，端銑刀44為右刀刃左螺旋，亦即，從柄部44a側觀看時刀刃44c以逆時鐘方向從柄部44a朝向刀刃部44b之前端之方式形 成螺旋狀，且脫離面44d比刀刃44c設於更靠柄部44a側時，端銑刀44係從柄部44a觀看時朝順時鐘方向旋轉，加工碎屑排出方向係從柄部44a朝向刀刃部44b之前端的方向。 As shown in Fig. 5(b), the end mill 44 is a right-edge left-helix, that is, when viewed from the side of the shank 44a, the blade 44c is shaped in a counterclockwise direction from the shank 44a to the front end of the blade 44b When it is spiral and the escape surface 44d is located closer to the shank 44a than the cutting edge 44c, the end mill 44 rotates clockwise when viewed from the shank 44a, and the machining chip discharge direction is from the shank 44a to the cutting edge. The direction of the front end of the portion 44b.

如圖5之(c)所示，端銑刀44為左刀刃右螺旋，亦即，從柄部44a側觀看時刀刃44c以順時鐘方向從柄部44a朝向刀刃部44b之前端的方式形成螺旋狀，且脫離面44d比刀刃44c設於更靠柄部44a側時，端銑刀44係從柄部44a觀看時朝逆時鐘方向旋轉，加工碎屑排出方向係從柄部44a朝向刀刃部44b之前端的方向。 As shown in Figure 5(c), the end mill 44 has a left-edge right-helix, that is, when viewed from the side of the shank 44a, the edge 44c forms a spiral in a clockwise direction from the shank 44a to the front end of the blade 44b And when the release surface 44d is located closer to the shank 44a than the cutting edge 44c, the end mill 44 rotates counterclockwise when viewed from the shank 44a, and the machining chip discharge direction is from the shank 44a to the front of the cutting edge 44b. The direction of the end.

如圖5之(d)所示，端銑刀44為左刀刃左螺旋，亦即，從柄部44a側觀看時刀刃44c以逆時鐘方向從柄部44a朝向刀刃部44b之前端的方式形成螺旋狀，且逃脫面44d比刀刃44c設於更靠刀刃部44b之前端側時，端銑刀44係從柄部44a觀看時朝逆時鐘方向旋轉，加工碎屑排出方向係從刀刃部44b之前端朝向柄部44a的方向。 As shown in Fig. 5(d), the end mill 44 has a left-edge left-helix, that is, when viewed from the side of the shank 44a, the blade 44c forms a spiral in a counterclockwise direction from the shank 44a to the front end of the blade 44b And when the escape surface 44d is located closer to the front end of the blade 44b than the blade 44c, the end mill 44 rotates counterclockwise when viewed from the shank 44a, and the machining chip discharge direction is from the front end of the blade 44b. The direction of the handle 44a.

因此，乾冰粒子之噴射方向EJ與端銑刀44之加工碎屑的排出方向為相反方向，且與端銑刀之柱狀部44z之軸為斜向地配置係如以下。亦即，如圖5之(a)及(d)，加工碎屑排出方向係從刀刃部44b之前端朝向柄部44a之方向時，噴射方向EJ係從柄部44a朝向刀刃部44b之前端的方向且相對於柱狀部44z之軸而成為斜向之方向。另一方面，如圖5之(b)及(c)，加工碎屑排出方向係從柄部44a朝向刀刃部44b之前端的方向時，噴射方向EJ係從刀刃部44b之前端朝向柄部44a的方向且相對於柱狀部44z之軸成為斜向之方向。 Therefore, the ejection direction EJ of the dry ice particles is opposite to the discharge direction of the processing chips of the end mill 44, and the axis of the columnar portion 44z of the end mill is arranged obliquely as follows. That is, as shown in Figure 5 (a) and (d), when the machining chip discharge direction is from the front end of the blade portion 44b to the shank 44a, the ejection direction EJ is from the shank 44a to the front end of the blade 44b. And it becomes an oblique direction with respect to the axis of the columnar portion 44z. On the other hand, as shown in Figure 5 (b) and (c), when the machining chip discharge direction is from the shank portion 44a to the front end of the blade portion 44b, the ejection direction EJ is from the front end of the blade portion 44b toward the shank portion 44a. The direction is oblique with respect to the axis of the columnar portion 44z.

從在加工時之碎屑排出的容易性來看，如圖5之(a)或(d)，以加工碎屑之排出方向為從刀刃部44b之前端朝向柄部44a之方向為佳。 From the perspective of the ease of chip discharge during processing, as shown in Figure 5 (a) or (d), the discharge direction of the processed chips is preferably from the front end of the blade portion 44b toward the shank portion 44a.

在圖5中，柱狀部44z之軸與噴射方向EJ所構成的角(銳角)α係可設為5至85°，以設為10至65°為佳。 In FIG. 5, the angle (acute angle) α formed by the axis of the columnar portion 44z and the injection direction EJ can be set to 5 to 85°, preferably 10 to 65°.

其次，參照圖4而說明從端銑刀44之柱狀部44z的軸方向觀看時之噴射方向EJ。 Next, referring to FIG. 4, the ejection direction EJ when viewed from the axial direction of the columnar portion 44z of the end mill 44 will be described.

從前述工具之旋轉的軸方向觀看，乾冰粒子之噴射方向EJ，亦即噴嘴420之軸之方向係只要朝向刀刃部44b即可，噴射方向EJ係以通過旋轉軸Q為較佳。 Viewed from the axis of rotation of the aforementioned tool, the jetting direction EJ of the dry ice particles, that is, the axis of the nozzle 420 only needs to be toward the blade portion 44b, and the jetting direction EJ preferably passes through the rotation axis Q.

乾冰粒子之噴射方向EJ較佳係使將端銑刀44之旋轉軸Q及端銑刀44之刀刃44c離開端面EF之點A連結的線B、與乾冰粒子之噴射方向EJ構成之角θ，以線B作為始點而在端銑刀44之旋轉方向進行測定時為0至180°。此係上切或下切皆相同。 The jetting direction EJ of dry ice particles is preferably such that the line B connecting the rotation axis Q of the end mill 44 and the point A where the cutting edge 44c of the end mill 44 leaves the end face EF, and the angle θ formed by the jetting direction EJ of the dry ice particles, When measuring the rotation direction of the end mill 44 with the line B as the starting point, it is 0 to 180°. The upper cut or the lower cut is the same in this system.

圖4之(a)的上切之情形，角θ係從防止在積層體之端面附著加工碎屑之觀點而言，以45至135°為較佳，圖4之(b)的下切之情形，亦從同樣之觀點而言，角θ係以90至180°為較佳。加工碎屑係可列舉膜之碎屑或黏著劑之碎屑等。 In the case of the upper cut in Fig. 4(a), the angle θ is from the viewpoint of preventing the adhesion of processing debris on the end face of the laminated body, 45 to 135° is preferable, and the case of the undercut in Fig. 4(b) From the same point of view, the angle θ is preferably 90 to 180°. Processing debris may include film debris or adhesive debris.

接著，說明乾冰粒子供給部300。如圖6所示，乾冰粒子供給部300係具備：液體二氧化碳源310、輸送氣體源330、連接液體二氧化碳源310及噴嘴420之管線L1、及、連接輸送氣體源330及噴嘴420之管線L2。 Next, the dry ice particle supply unit 300 will be described. As shown in FIG. 6, the dry ice particle supply unit 300 includes a liquid carbon dioxide source 310, a conveying gas source 330, a pipeline L1 connecting the liquid carbon dioxide source 310 and a nozzle 420, and a pipeline L2 connecting the conveying gas source 330 and the nozzle 420.

在管線L1係設有閥門340及孔口350，在管線L2係設有閥門360。 The pipeline L1 is provided with a valve 340 and an orifice 350, and the pipeline L2 is provided with a valve 360.

開啟閥門340而使液體二氧化碳源310之液體以孔口350隔熱膨脹而生成乾冰粒子(乾冰雪)，並送至噴嘴420。可開啟閥門360，而從輸送氣體源330將氣體供給至噴嘴420，並從噴嘴420將乾冰粒子以氣體吹出，使其朝向端銑刀44之刀刃部44b噴射，並碰撞刀刃部44b。 The valve 340 is opened to make the liquid of the liquid carbon dioxide source 310 adiabaticly expand through the orifice 350 to generate dry ice particles (dry ice and snow), which are sent to the nozzle 420. The valve 360 can be opened, and the gas is supplied from the conveying gas source 330 to the nozzle 420, and the dry ice particles are blown out with the gas from the nozzle 420, so that they are sprayed toward the blade portion 44b of the end mill 44 and collide with the blade portion 44b.

使其碰撞之乾冰粒子的平均粒徑並無特別限定，但加工碎屑之中，從有效率地去除黏著劑之碎屑的觀點而言，以100μm以上為較佳。又，從抑制黏著劑層受到乾冰之碰撞而缺少之觀點而言，以1000μm以下為較佳。乾冰粒子之平均粒徑係可藉由雷射都卜勒(laser doppler)流速計測定。 The average particle size of the dry ice particles to collide is not particularly limited, but among the processed scraps, from the viewpoint of efficiently removing the adhesive scraps, 100 μm or more is preferable. In addition, from the viewpoint of suppressing the adhesive layer from being collided with dry ice and lacking, it is preferably 1000 μm or less. The average particle size of dry ice particles can be measured with a laser doppler flow meter.

使其碰撞之乾冰粒子的速度係可設為5m/sec至100m/sec。 The speed of the dry ice particles colliding with each other can be set from 5m/sec to 100m/sec.

乾冰之輸送氣體並無特別限定，而可設為例如氮、空氣、二氧化碳。 The transport gas of dry ice is not particularly limited, and can be, for example, nitrogen, air, or carbon dioxide.

乾冰粒子之粒徑係可藉由以孔口350使其隔熱膨脹後以噴嘴420吹出為止之距離(隔熱膨脹距離)、或藉由噴嘴420與乾冰粒子之供給對象的距離(噴射距離)來調節。 The particle size of the dry ice particles can be determined by the distance between the nozzle 420 and the nozzle 420 for thermal insulation expansion through the orifice 350 (thermal insulation expansion distance), or the distance between the nozzle 420 and the supply target of the dry ice particles (spray distance) To adjust.

噴嘴420與刀刃部44b之距離(噴射距離)以設為未達20mm為佳。又，隔熱膨脹距離例如可設為10至500mm。 The distance (spray distance) between the nozzle 420 and the blade portion 44b is preferably less than 20 mm. In addition, the adiabatic expansion distance can be set to 10 to 500 mm, for example.

(端面加工方法及端面加工膜之製造方法) (End surface processing method and manufacturing method of end surface processing film)

接著，說明本發明之實施型態的端面加工方法及端面加工膜之製造方法。 Next, the end surface processing method and the manufacturing method of the end surface processed film of the embodiment of the present invention will be described.

首先，準備上述之積層體10。積層體之端面EF成為本實施型態之加工對象。 First, the above-mentioned laminated body 10 is prepared. The end face EF of the laminated body becomes the processing object of this embodiment.

接著，將該積層體10如圖3所示，夾持在一對接觸構件22之間，以押壓部60將一者之接觸構件22朝向另一者之接觸構件22進行押壓，並固定積層體10。 Next, as shown in FIG. 3, the laminated body 10 is sandwiched between a pair of contact members 22, and one contact member 22 is pressed toward the other contact member 22 by the pressing portion 60, and fixed Stacked body 10.

接著，在固定積層體10之狀態下，對於積層體10之端面EF，使繞與積層體10之厚度方向平行的軸周圍旋轉之端銑刀44的刀刃部44b之外周面接觸，同時並使端銑刀44沿著端面EF朝與厚度方向正交之方向例如長邊或短邊方向移動，而進行各端面EF之加工(A步驟)。加工之具體例係可列舉切削。藉此，可精度良好地使構成積層體10之各光學膜12的平面形狀(尺寸、直角度等)形成預定之形狀。 Next, with the layered body 10 fixed, the end face EF of the layered body 10 is brought into contact with the outer peripheral surface of the edge portion 44b of the end mill 44 that rotates around an axis parallel to the thickness direction of the layered body 10. The end mill 44 moves along the end face EF in a direction orthogonal to the thickness direction, for example, the long side or the short side direction, to process each end face EF (step A). Specific examples of processing include cutting. Thereby, the planar shape (size, right angle, etc.) of each optical film 12 constituting the laminated body 10 can be accurately formed into a predetermined shape.

在此，係可加工積層體10之全端面EF之中的75%以上，亦可加工該全端面EF之中的90%以上、95%以上、99%以上、或100%。 Here, more than 75% of the full end face EF of the layered body 10 can be processed, and more than 90%, more than 95%, more than 99%, or more than 100% of the full end face EF can be processed.

與該切削加工同時地，從噴嘴420噴射乾冰粒子，使其碰撞刀刃部44b(B步驟)。在此，係以在端銑刀44沿著積層體10之端面EF相對性移動並進行研削之際，將乾冰粒子朝端銑刀44之刀刃部44b持續噴射為佳。 Simultaneously with this cutting process, dry ice particles are sprayed from the nozzle 420 so that they collide with the blade portion 44b (step B). Here, when the end mill 44 is relatively moved along the end face EF of the laminated body 10 for grinding, it is preferable to continuously spray dry ice particles toward the blade portion 44 b of the end mill 44.

切削終止後，解除以押壓部60進行的押壓，從一對接觸構件22間取出積層體10，藉此可精度佳地獲得經端面加工之積層體10。依需要，而藉由從積層體10分離各光學膜12，可獲得經分離之光學膜12。 After the cutting is finished, the pressing by the pressing portion 60 is released, and the laminated body 10 is taken out from between the pair of contact members 22, whereby the laminated body 10 with the end face processed can be obtained with high precision. If necessary, by separating each optical film 12 from the laminated body 10, a separated optical film 12 can be obtained.

依據本實施型態，因在切削加工中使乾冰粒子碰撞端銑刀44之刀刃部44b，故可將在研削加工中產生之加工碎屑從端銑刀44之刀刃部44b隨時除去。藉此，可抑制因附著於刀刃部之碎屑而使加工精度降低。 According to this embodiment, since the dry ice particles collide with the edge portion 44b of the end mill 44 during the cutting process, machining debris generated during the grinding process can be removed from the edge portion 44b of the end mill 44 at any time. Thereby, it is possible to suppress the reduction in machining accuracy due to the debris adhering to the blade portion.

尤其，積層體10具有黏著劑層時，雖然黏著劑之碎屑容易附著於刀刃部，但依據本實施型態，可在切削中從刀刃部去除黏著劑之碎屑，故效果高。 In particular, when the laminated body 10 has an adhesive layer, although the debris of the adhesive is easy to adhere to the blade portion, according to this embodiment, the debris of the adhesive can be removed from the blade portion during cutting, so the effect is high.

本發明係不受上述實施型態限定，而可為各種的變形態樣。 The present invention is not limited by the above-mentioned embodiments, but can be in various modifications.

例如，膜及積層體10之形狀係不限於圖2之形狀而可採取任意之形狀。例如，外形形狀可為橢圓(包含長圓)或圓形。又，A步驟之切削步驟較佳為使積層體10之端面之內、從厚度方向觀看積層體之凸部、凹部、或非直線部接觸端銑刀來進行。 For example, the shape of the film and the laminate 10 is not limited to the shape of FIG. 2 and may take any shape. For example, the outer shape may be an ellipse (including an oblong circle) or a circle. In addition, the cutting step of step A is preferably performed by contacting the end mill with the convex portion, concave portion, or non-linear portion of the laminated body viewed from the thickness direction within the end face of the laminated body 10.

又，在上述實施型態，在A步驟之加工對象為積層體10之外側的端面EF，但亦可不為端面EF，亦可為如孔洞之內部的內側之端面。 In addition, in the above-mentioned embodiment, the processing object in the A step is the end face EF on the outer side of the laminated body 10, but it may not be the end face EF, and may be the inner end face such as the inside of a hole.

例如，如圖7之(a)，可在A步驟中，使端銑刀44之軸平行於積層體10之厚度方向配置之後，以柱狀部44z在積層體10之厚度方向的上表面10S形成凹部之方式使柱狀部44z相對於積層體10相對性移動，而在積層體10開洞。此時，可在A步驟中，以柱狀部44z朝積層體10之厚度方向貫通之方式使柱狀部44z相對於積層體10而相對性移動。藉此，可設置貫通於積層體10之孔洞部，並可在各光學膜12開貫通孔。 For example, as shown in Figure 7(a), in step A, after the axis of the end mill 44 is arranged parallel to the thickness direction of the laminate 10, the columnar portion 44z is placed on the upper surface 10S of the laminate 10 in the thickness direction. The method of forming the recessed portion is such that the columnar portion 44z relatively moves with respect to the laminated body 10 to make a hole in the laminated body 10. At this time, in the A step, the columnar portion 44z can be moved relative to the layered body 10 so that the columnar portion 44z penetrates in the thickness direction of the layered body 10. Thereby, a hole portion penetrating through the laminated body 10 can be provided, and a through hole can be opened in each optical film 12.

又，如圖7之(b)所示，可在A步驟中，在貫通後使端銑刀44呈渦漩狀(螺旋狀)旋轉，而擴展孔洞部TH之直徑。 In addition, as shown in FIG. 7(b), in step A, the end mill 44 may be rotated in a spiral shape (spiral shape) after penetration to expand the diameter of the hole portion TH.

再者，如圖8所示，亦可在A步驟中，使端銑刀44之軸平行於積層體10之厚度方向配置之後，使端銑刀44從積層體10之上表面10S朝向下表面10B，而呈螺線狀(螺旋狀)移動。藉此，柱狀部44z從積層體10之厚度方向的上表面10S擴展凹部之直徑，同時亦擴展深度，可形成較大的貫通孔。 Furthermore, as shown in FIG. 8, in step A, after the axis of the end mill 44 is arranged parallel to the thickness direction of the laminated body 10, the end mill 44 is moved from the upper surface 10S of the laminated body 10 to the lower surface 10B, while moving in a spiral (spiral) shape. Thereby, the columnar part 44z expands the diameter of the recessed part from the upper surface 10S of the thickness direction of the laminated body 10, and also expands the depth, and a larger through hole can be formed.

而且，進行上述之各A步驟時，亦藉由進行上述之B步驟，可抑制端銑刀之刀刃部44b的碎屑之附著。 Moreover, when performing each of the above-mentioned steps A, by performing the above-mentioned step B, it is possible to suppress adhesion of chips on the edge portion 44b of the end mill.

再者，噴嘴420之開口部的形狀亦不限定於圓形。例如，如圖9所示，可使噴嘴420之開口部42a的形狀設為長孔形狀。此時，使長孔之軸方向設為與柱狀部44z之軸為平行，亦即，以開口部42a面向刀刃部44b之方式構成為佳。長孔之軸方向長度係可依照刀刃部44b之長度而適當設定。 Furthermore, the shape of the opening of the nozzle 420 is not limited to a circular shape. For example, as shown in FIG. 9, the shape of the opening 42a of the nozzle 420 may be a long hole shape. At this time, it is preferable to make the axis direction of the long hole parallel to the axis of the columnar portion 44z, that is, to configure the opening portion 42a to face the blade portion 44b. The length of the long hole in the axial direction can be appropriately set according to the length of the blade portion 44b.

在上述實施型態係為了對切削時進行移動之工具吹附乾冰粒子，而使噴嘴420被固定於移動部46，但亦可被固定於旋轉部42。 In the above embodiment, the nozzle 420 is fixed to the moving part 46 in order to blow dry ice particles on the tool moving during cutting, but it may also be fixed to the rotating part 42.

如圖10所示，具有與端銑刀44之移動部46不同的噴嘴420用之移動部46’亦可實施。此時，從垂直於端銑刀44之柱狀部44z的軸之方向觀看，可使噴嘴420之噴射方向EJ設為與端銑刀之柱狀部44z正交之方向，且使噴嘴420沿著端銑刀44之柱狀部的軸方向而進行往返掃描運動。 As shown in Fig. 10, a moving part 46' for the nozzle 420 which is different from the moving part 46 of the end mill 44 can also be implemented. At this time, when viewed from the direction perpendicular to the axis of the columnar portion 44z of the end mill 44, the spray direction EJ of the nozzle 420 can be set to be a direction orthogonal to the columnar portion 44z of the end mill, and the nozzle 420 can be aligned along The reciprocating scanning movement is performed in the axial direction of the columnar portion of the end mill 44.

當然加工部40、押壓部60之態樣亦不限定於上述之態樣。例如，在上述實施型態係使用端銑刀44作為工具，但亦可使用端銑刀以外之工具，例如刨刀。又，可使用在旋轉圓板之一面上設有切削刀刃的平面研削工具。又，亦可使用具有研磨粒作為刀刃之工具，此時，係不進行切削步驟，而可進行研磨步驟。即使在如此之情形，在切削或研磨中，亦可藉由使乾冰粒子碰撞工具之刀刃，抑制伴隨加工碎屑之附著的切削精度之降低或研磨效率之降低。 Of course, the aspect of the processing part 40 and the pressing part 60 is not limited to the above-mentioned aspect. For example, in the above embodiment, the end mill 44 is used as a tool, but a tool other than the end mill may also be used, such as a planer. In addition, a flat grinding tool with a cutting blade provided on one surface of the rotating disc can be used. In addition, a tool having abrasive grains as a blade can also be used. In this case, the cutting step is not performed, and the polishing step can be performed. Even in this case, during cutting or grinding, the dry ice particles can collide with the cutting edge of the tool to suppress the reduction in cutting accuracy or the reduction in grinding efficiency accompanying the adhesion of processing chips.

在上述實施型態雖然固定部61在下方，押壓部60在上方，但亦可相反地配置，不具有固定部，而可將一對押壓部60分別配置在上下。 In the above embodiment, although the fixing portion 61 is on the lower side and the pressing portion 60 is on the upper side, the arrangement may be reversed. The fixing portion is not provided, and the pair of pressing portions 60 may be arranged on the upper and lower sides, respectively.

在上述實施型態係相對於積層體10，藉由移動部46使端銑刀44移動，但只要端銑刀與積層體10相對地移動即可，例如，固定端銑刀44，並以移動部使積層體10相對於端銑刀移動亦可實施。 In the above-mentioned embodiment, the end mill 44 is moved relative to the laminated body 10 by the moving part 46, but it is sufficient that the end mill and the laminated body 10 move relatively, for example, the end mill 44 is fixed and moved It is also possible to move the layered body 10 relative to the end mill.

積層體加工裝置100係只要具有1個加工部40即可，但從迅速地進行加工之觀點而言，亦可具有2個以上之加工部40。此時，可在各別之加工部設有噴嘴420。 The laminated body processing apparatus 100 only needs to have one processing section 40, but from the viewpoint of rapid processing, it may have two or more processing sections 40. At this time, nozzles 420 may be provided in the respective processing parts.
