Description
本發明係有關一種金屬板件的製造方法，尤其係有關一種具有精細紋路的金屬板件的製造方法。The present invention relates to a method of manufacturing a metal sheet member, and more particularly to a method of manufacturing a sheet metal member having fine lines.
隨著資訊科技之迅速發展，攜帶型電子裝置如行動電話、PDA(Personal Digital Assistant，個人數位助理)及筆記本電腦等應用日益普遍，這些電子裝置外殼之美觀程度及手感也愈來愈受到消費者之關注與重視。尤其，提供高質感及表面光澤的金屬外殼更是廣泛應用於這些攜帶型電子裝置。With the rapid development of information technology, portable electronic devices such as mobile phones, PDAs (Personal Digital Assistants) and notebook computers are becoming more and more popular. The aesthetics and feel of these electronic device casings are becoming more and more popular among consumers. Concern and attention. In particular, metal housings that provide high texture and surface gloss are widely used in these portable electronic devices.
習知可在金屬外殼的表面產生紋路的方法包含：A conventional method of creating a texture on the surface of a metal casing includes:
1. 沖壓產品(例如金屬飾板、機殼)，其成形原理是利用重力沖製金屬工件，以使其具有所希望的外型。但是以此方式製成的產品容易有立體感不佳、紋路不細緻、表面不平滑等缺點。1. Stamping products (such as metal plaques, casings), the forming principle is to use gravity to punch metal workpieces to have the desired shape. However, products made in this way are prone to shortcomings such as poor three-dimensionality, inconspicuous texture, and uneven surface.
2. 以目前市售之手機產品而言，其金屬外殼表面精緻紋路仍以雷雕、蝕刻及熱轉印為主。然而，上述方法僅限於產品的平面區域，都無法在產品的側壁或轉角上提供連續性的精細紋路，或是在側壁或轉角上的紋路易變形或斷裂，導致產品不良率升高，造成材料的浪費。2. In terms of the currently available mobile phone products, the surface of the metal casing is still exquisitely polished, etched and heat transferred. However, the above method is limited to the flat area of the product, and it is impossible to provide continuous fine lines on the side walls or corners of the product, or the lines on the side walls or corners are easily deformed or broken, resulting in an increase in product defective rate, resulting in materials. Waste.
3. 以表面噴塗烤漆等方法進行裝飾，以加強其外觀之美感。然而上述方法可能會影響產品外觀的金屬質感。再者，藉由噴塗烤漆等方法形成之表面耐磨性較差，表面極易磨損且其噴塗之烤漆易剝落，從而影響產品外觀及耐用性。若要經由噴塗烤漆使金屬外殼表面具有圖案花紋等，將會使加工工序更加複雜。3. Decorate the surface with a paint spray to enhance the aesthetic appearance. However, the above methods may affect the metallic texture of the appearance of the product. Moreover, the surface formed by spraying paint and the like has poor surface abrasion resistance, the surface is extremely easy to wear and the painted paint is easily peeled off, thereby affecting the appearance and durability of the product. If the surface of the metal casing is patterned by spraying paint, the processing will be more complicated.
4. 公開第200922741號台灣專利揭露一種金屬外殼及其製作方法，其是以沖壓製成半成品，再於該半成品的表面以數控機床進行機械加工，而在金屬外殼表面呈現加工後的圖案。然而，上述技術無法製作較細微之紋路，且其紋路亦無法呈現在產品外殼的側壁及轉角處。4. Taiwan Patent No. 200922741 discloses a metal casing and a manufacturing method thereof, which are formed into a semi-finished product by stamping, and then machined by a numerically controlled machine tool on the surface of the semi-finished product, and a processed pattern is formed on the surface of the metal casing. However, the above technique cannot produce a finer texture, and its texture cannot be presented on the side walls and corners of the product casing.
基於上述可知，目前對於金屬殼件曲面無法呈現連續性細緻紋路的問題仍未見較妥善的解決方案。Based on the above, there is still no suitable solution for the problem that the curved surface of the metal shell cannot exhibit continuous fine lines.
職是之故，發明人鑑於習知技術之缺失，乃經悉心試驗與研究並一本鍥而不捨之精神，終發明出一種新穎且具有連續性精細紋路之金屬板件及其製造方法，此發明將可解決上述習知技術之缺點，以下為本發明之簡要說明。In the light of the job, the inventor, in view of the lack of the prior art, was carefully tested and researched with a perseverance spirit, and finally invented a novel and continuous fine grain metal sheet and a manufacturing method thereof. The disadvantages of the above-mentioned prior art can be solved, and the following is a brief description of the present invention.
本案所提供方法可在金屬產品的平板及側板承接處的直角邊或弧角邊上仿真各種連續紋路，特別是石紋、皮紋、葉紋、花瓣紋路、木紋等深淺不一或錯綜複雜的仿生圖紋，以提高產品的質感和價值，並體現產品外觀的層次感。此外，因本案之方法所產生的金屬板件的精細紋路是直接成形於金屬上，無須額外的噴漆或機械雕刻等表面加工步驟，且可避免傳統沖壓製程易產生的外觀損壞(包含側壁或轉角上的紋路變形或斷裂)，故本案的製造方法可提高產品的良率及降低損耗所造成材料的浪費。The method provided in the present invention can simulate various continuous lines on the right side or the arc side of the flat plate and the side plate of the metal product, especially the stone, the grain, the leaf, the petal, the wood grain and the like. Bionic maps to enhance the texture and value of the product, and reflect the layering of the product's appearance. In addition, the fine grain of the metal sheet produced by the method of the present invention is directly formed on the metal, and no additional surface processing steps such as painting or mechanical engraving are required, and the appearance damage easily caused by the conventional stamping process (including the side wall or the corner) can be avoided. The texture of the upper surface is deformed or broken. Therefore, the manufacturing method of the present invention can improve the yield of the product and reduce the waste of materials caused by the loss.

本案得藉由下列詳細說明，俾得更深入之了解：The case can be further explained by the following detailed explanation:
本發明將藉由下述之較佳實施例及其配合之圖式，做進一步之詳細說明。The invention will be further described in detail by the following preferred embodiments and the accompanying drawings.
特別要說明的是，在本發明所揭露之金屬板件製成方法之中，紋路、圖案、圖紋等名詞係可相互替代使用，其包含由單一或多線條所構成無意義或有意義的圖案。另外，曲面、角隅、R角及轉角等名詞亦可相互替代使用。In particular, in the method for manufacturing a metal sheet disclosed in the present invention, nouns such as lines, patterns, patterns, and the like can be used interchangeably, and include a meaningless or meaningful pattern composed of single or multiple lines. . In addition, terms such as curved surfaces, corners, R angles, and corners can also be used interchangeably.
請參考第一圖，其為本案所提金屬板件製成方法的第一較佳實施例的流程圖。上述方法包含如下步驟：提供金屬板(步驟101)：該金屬板的材質依據所欲成形板件產品的需求而異，例如可以是金、銀、銅、鋁、鈦、鐵或其合金等。為達特殊材料的機械性質，亦可採用透過輥軋而使兩種或兩種以上之金屬材料合而為一的複合金屬，以增加功能性、減少材料厚度並降低高單價金屬的使用量。該金屬板的厚度基本上與欲成形工件(例如手機外殼)的厚度相同。然而，只要可以完成後續步驟，該金屬板的厚度並不設限。Please refer to the first figure, which is a flow chart of the first preferred embodiment of the method for manufacturing a metal sheet member. The above method comprises the steps of: providing a metal plate (step 101): the material of the metal plate varies depending on the requirements of the product to be formed, and may be, for example, gold, silver, copper, aluminum, titanium, iron or alloys thereof. In order to achieve the mechanical properties of a particular material, a composite metal in which two or more metal materials are combined by rolling can be used to increase functionality, reduce material thickness, and reduce the use of high monovalent metals. The thickness of the metal sheet is substantially the same as the thickness of the workpiece to be formed, such as a casing of a mobile phone. However, the thickness of the metal plate is not limited as long as the subsequent steps can be completed.
在金屬板上形成紋路(步驟102)：在本實施例中，產生紋路的方法包含各種習知能在金屬板的表面上圖案化的方法，例如蝕刻、雷射雕刻、電磁成形(electromagneric forming)、板材軋延(roll forming)或曝光顯影等。該紋路可佈滿於金屬板的表面，但本發明並不以此為限，該紋路可以僅形成於表面的局部。Forming a texture on the metal plate (step 102): In the present embodiment, the method of generating the texture includes various conventional methods of patterning on the surface of the metal plate, such as etching, laser engraving, electromagneric forming, Sheet forming, exposure development, and the like. The texture may be covered on the surface of the metal plate, but the invention is not limited thereto, and the texture may be formed only on a part of the surface.
板液壓成形(Sheet Hydroforming，SHF)：針對最終欲成形工件(例如筆記型電腦外殼)的外形進行板液壓成形，以形成表面具有精細紋路且具有至少一曲面(或角隅，即一般所稱的R角)的金屬殼件，其中，該精細紋路可以僅位於該至少一曲面上，亦可延伸至與該至少一曲面相接的平面上。Sheet Hydroforming (SHF): hydroforming a sheet for the shape of the final workpiece to be formed, such as a notebook case, to form a surface with fine lines and at least one curved surface (or corner, commonly known as The metal shell member of the R angle, wherein the fine grain may be located only on the at least one curved surface or may extend to a plane that is in contact with the at least one curved surface.
請參考第二圖，其為本案所提金屬板件製成方法的第二較佳實施例的流程圖。若欲產生仿生圖紋，如皮紋、葉紋、木紋等深淺不一且相對較精細的紋路，較佳是採用示於第二圖中的方法於金屬板上形成精細紋路。首先，提供具有精緻紋路的原型模(步驟201)，該原型模亦可取自自然界，例如具有複雜紋路的皮革、葉片、花瓣、石頭、木頭等。接著，以該原型模為模板依據所需厚度進行電鑄，以形成金屬模具(步驟203)。電鑄技術的基本分類有金屬電鑄如Ni、Cu、Au、Ag、Pt等；合金電鑄如Ni-Fe、Ni-Co、Ni-Mn、Ni-W等，及複合電鑄如Ni-SiC、Ni-Al2O3、Ni-鑽石等。雖然任何可以電鑄的金屬或合金皆能作為電鑄金屬模具的材質，但在本實施例較佳的電鑄材料是Ni金屬或Ni-Co合金。在電鑄過程中，將原型模放入裝有電鑄溶液之槽體中，並與直流電源的陰極導通，陽極的金屬(例如Ni金屬或Ni-Co合金)則溶解沈積於陰極的原形模的表面，形成金屬模具，待達到所需的金屬厚度時，原形模及附著於其上的金屬模具即可自電鑄溶液取出。因電鑄技術應用的電化學原理是屬於離子電沉積的方式，其把溶液中的金屬離子還原成金屬，能完全地複製原型模上的細微紋路。因此，由本案之方法產生的金屬模具可幾乎完全複製木頭、皮革、花草、天然石材等圖案，其線條之流暢與機械加工出來的剛硬線條迥異。當原型模本身不具導電性時，可先對原型模進行銀鏡處理(步驟202)。即利用例如塗佈、真空蒸鍍，真空濺鍍或噴墨等方式將導電層(例如金、銀或鉻等導電材料)設置於原型模的精細紋路表面，以增加原型模於進行後續電鑄步驟時的導電性。也就是說，當原型模本身即具導電性時，此步驟亦可省略，即可直接進行電鑄步驟(步驟203)。Please refer to the second figure, which is a flow chart of a second preferred embodiment of the method for manufacturing a metal sheet according to the present invention. If a bionic pattern, such as a grain, a leaf, a wood grain, or the like, which is different in depth and relatively fine, is desired, it is preferable to form a fine grain on the metal plate by the method shown in the second figure. First, a prototype mold having a refined texture is provided (step 201), which can also be taken from nature, such as leather, leaves, petals, stones, wood, etc. with complex lines. Next, electroforming is performed according to the required thickness using the prototype mold as a template to form a metal mold (step 203). The basic classification of electroforming technology includes metal electroforming such as Ni, Cu, Au, Ag, Pt, etc.; alloy electroforming such as Ni-Fe, Ni-Co, Ni-Mn, Ni-W, etc., and composite electroforming such as Ni- SiC, Ni-Al2O3, Ni-diamond, etc. Although any metal or alloy that can be electroformed can be used as the material of the electroforming metal mold, the preferred electroforming material in this embodiment is a Ni metal or a Ni-Co alloy. In the electroforming process, the prototype mold is placed in a tank containing an electroforming solution and is electrically connected to the cathode of the direct current power source, and the metal of the anode (for example, Ni metal or Ni-Co alloy) dissolves the original mold deposited on the cathode. The surface forms a metal mold, and when the desired metal thickness is reached, the original mold and the metal mold attached thereto can be taken out from the electroforming solution. The electrochemical principle applied by electroforming technology belongs to the method of ion electrodeposition, which reduces the metal ions in the solution to metal and completely replicates the fine lines on the prototype. Therefore, the metal mold produced by the method of the present invention can almost completely replicate the patterns of wood, leather, flowers, natural stones, etc., and the smoothness of the lines is different from the rigid lines machined. When the prototype mold itself is not electrically conductive, the prototype mold may be subjected to silver mirror processing (step 202). That is, a conductive layer (for example, a conductive material such as gold, silver or chromium) is placed on the fine grain surface of the prototype mold by, for example, coating, vacuum evaporation, vacuum sputtering or ink jet, to increase the prototype mold for subsequent electroforming. Conductivity at the time of the step. That is to say, when the prototype mold itself is electrically conductive, this step can also be omitted, and the electroforming step can be directly performed (step 203).
接著以該金屬模具進行電磁成形(步驟204A)或板材軋延(步驟204B)，以形成帶有該精細紋路的金屬板。在軋延製程前，須將上述帶有精細紋路的金屬模具(通常為金屬片的形式)以紋路朝外的方式包覆於圓輥上，接著使用該圓輥對金屬板的表面進行軋延，以將金屬模具上的精細紋路複製於金屬板的表面上。而本案中電磁成形的方法可利用本國專利公開第201021935號專利「製作具表面圖紋之板材之裝置及其方法」所揭露的方法進行。最後，針對帶有精細紋路的金屬板進行板液壓成形(步驟205)。表面具有精細紋路的金屬板藉由板液壓成形製程，形成具有至少一曲面(或角隅，即R角)的金屬殼件。以此實施例而言，該金屬殼件可另外包含一底板(平面)，該底板的一端與該曲面(或角隅)的一端連接。Electroforming (step 204A) or sheet rolling (step 204B) is then performed with the metal mold to form a metal plate with the fine grain. Before the rolling process, the above-mentioned fine-grained metal mold (usually in the form of a metal sheet) is coated on the round roll with the grain facing outward, and then the surface of the metal sheet is rolled using the round roll. To replicate the fine lines on the metal mold on the surface of the metal plate. The method of electromagnetic forming in the present invention can be carried out by the method disclosed in the "Apparatus and method for producing a sheet having a surface pattern" in the patent of the Japanese Patent Publication No. 201021935. Finally, the plate is hydroformed for the metal plate with fine grain (step 205). The metal plate having a fine grain on the surface is formed by a plate hydroforming process to form a metal shell member having at least one curved surface (or corner angle, that is, an R angle). In this embodiment, the metal shell member may additionally include a bottom plate (planar) having one end connected to one end of the curved surface (or corner).
請參考第三圖，其為本案第一及第二較佳實施例中板材液壓成形步驟的示例製程。請參考第三圖(A)，首先，先在下層的母模30的液壓室31中充以一定量的液體介質(例如油、水等)，將帶有精細紋路的金屬板32置於液壓室31上(精細紋路朝向液體介質)，並將公模(沖頭)33及壓料板34設置於適當位置。接著，壓下壓料板34夾緊金屬板32(如第三圖(B)所示)。最後，利用公模33下壓的壓力與液壓室31內之液體介質所產生的對向壓力而使得金屬板32變形為所欲形狀(如第三圖(C)及(D)所示)。針對所使用金屬板的材質，即使是難以成形的材料(如不銹鋼、高強度鋼、鈦等)，於此製程中均可利用壓力的控制達到成形的目的。此製程亦稱為液壓機械深引伸(Hydromechanical Deep Drawing)或對向液壓成形，其可提高工件的引伸深度與精度、提升生產效益，並減少傳統板材製作時所產生的缺陷。本案利用上述技術針對一產品(例如手機殼件)的外形進行金屬板的塑形，以使金屬板變形為表面具有該精細紋路的金屬板件(金屬殼件)。因板液壓成形的應變速率很慢，所以在金屬殼件成形的過程中，其曲面不易受到破壞或變形，也因此可以確保具有紋路的金屬板在彎折後，其彎折處(即該金屬殼件的曲面)仍具有紋路，也就是說，該紋路可以完整地及連續地形成於該金屬殼件的表面，包含在曲面(或角隅)處。為了能加強保護金屬殼件曲面處的紋路，可在板液壓成形步驟之前，預先在金屬板將會形成曲面(或角隅)之處的紋路上設置一保護機構，例如貼上一層高分子保護膜，以降低液壓過程中液體介質對曲面(或角隅)處的紋路所造成的衝擊。Please refer to the third figure, which is an exemplary process of the hydraulic forming step of the sheet material in the first and second preferred embodiments of the present invention. Referring to the third figure (A), first, a certain amount of liquid medium (for example, oil, water, etc.) is first filled in the hydraulic chamber 31 of the lower mother mold 30, and the metal plate 32 with fine lines is placed in the hydraulic pressure. On the chamber 31 (the fine grain faces the liquid medium), the male mold (punch) 33 and the pressure plate 34 are placed in position. Next, the pressure plate 34 is pressed to clamp the metal plate 32 (as shown in the third diagram (B)). Finally, the metal plate 32 is deformed into a desired shape by using the pressure depressed by the male mold 33 and the opposing pressure generated by the liquid medium in the hydraulic chamber 31 (as shown in the third figures (C) and (D)). For the material of the metal plate to be used, even a material that is difficult to form (such as stainless steel, high-strength steel, titanium, etc.) can be controlled by pressure during the process. This process, also known as Hydromechanical Deep Drawing or Counter Hydroforming, increases the depth and precision of the workpiece, increases production efficiency, and reduces defects in traditional sheet making. In the present case, the metal plate is shaped by the above-mentioned technology for the shape of a product (for example, a mobile phone case), so that the metal plate is deformed into a metal plate member (metal case member) having the fine grain on the surface. Since the strain rate of the hydroforming of the plate is very slow, the curved surface of the metal shell is not easily damaged or deformed during the forming process of the metal shell, and thus the metal sheet having the grain is bent, and the bent portion (ie, the metal) The curved surface of the shell member still has a texture, that is, the texture can be formed completely and continuously on the surface of the metal shell member, including at the curved surface (or corner). In order to strengthen the protection of the grain at the curved surface of the metal shell, a protective mechanism may be provided in advance on the grain where the metal plate will form a curved surface (or corner) before the hydroforming step of the plate, for example, a layer of polymer protection is applied. Membrane to reduce the impact of the liquid medium on the surface (or corner) of the hydraulic process.
使用上述較佳實施例的方法可用於製成具有精細花紋的金屬製品，該金屬製品可用於3C產品外殼(如筆記型電腦、行動電話、數位相機、衛星導航器等的外殼、家電外殼)、燈飾外罩、汽車內裝飾部件、文具用品(如名片盒)的殼體等，以增添產品整體美感及高貴典雅的設計。此外，因深淺不一的精細花紋是直接形成於金屬製品上，故可讓使用者有立體圖案層的特殊觸感。The method of the preferred embodiment described above can be used to produce a metal product having a fine pattern, which can be used for a 3C product casing (such as a notebook computer, a mobile phone, a digital camera, a satellite navigation device, and the like). The lighting cover, the interior decoration parts of the car, the housing of the stationery (such as a business card case), etc., to add the overall aesthetic and elegant design of the product. In addition, since the fine patterns of different shades are formed directly on the metal product, the user can have a special touch of the three-dimensional pattern layer.
再者，由本案之方法所產生的金屬板件不只在一平面上有細緻的紋路，尤其在側壁或轉角的曲面處也能完整呈現連續性的細緻紋路。以手機背部殼件為例，其同時可以在由殼件平面向外延伸的另四個面(側壁)及其R角處產生連續性的細緻紋路。也就是說，背殼的五面及R角皆有連續性紋路，此效果並非傳統精密加工方式所能輕易達成。此外，由於本案方法所產生的金屬殼件上的紋路是與該金屬殼件本體一體成形，故不但可避免因表面貼膜等額外工序影響產品外觀的金屬質感，亦無脫膜、薄膜扭曲變形、圖案脫落等缺陷。因此，本案的方案具有簡化製程、提高良率及節省成本等優勢，堪稱為相當具有競爭力的新穎方法。Moreover, the metal sheet produced by the method of the present invention not only has a fine texture on one plane, but also can continuously exhibit a continuous fine texture at the curved surface of the side wall or the corner. Taking the case of the back of the mobile phone as an example, it can simultaneously produce a continuous fine line on the other four faces (side walls) extending outward from the plane of the shell member and its R corner. That is to say, the five sides and the R angle of the back shell have continuous lines, which is not easily achieved by conventional precision processing methods. In addition, since the texture on the metal shell member produced by the method of the present invention is integrally formed with the metal shell member body, not only the metal texture which affects the appearance of the product due to an additional process such as surface filming, but also the film peeling, the film distortion and deformation, Defects such as pattern shedding. Therefore, the solution of this case has the advantages of simplifying the process, improving the yield and saving the cost, and is called a novel and competitive method.
