Description
本發明與一種天線裝置及其製作方法有關。具體言之，其係關於一種利用模內成型製程製作之天線裝置及其方法。The invention relates to an antenna device and a method of fabricating the same. Specifically, it relates to an antenna device fabricated by an in-mold forming process and a method thereof.
模內裝飾(In-Mold Decoration,IMD)是目前風行的表面裝飾技術，其主要應用在家電產品的表面裝飾及功能性面板、手機視窗鏡片及外殼、洗衣機控制台、冰箱控制台、空調裝置控制台、汽車儀錶盤等多種家電的面板、標誌等外觀物件之製作。模內裝飾的技術要點在於把一個印有圖案的薄膜放到模具裡進行注塑(Injection Molding，又稱射出成型)動作。當塑件成型後，上述帶有圖案的薄膜會與塑料融為一體，使圖案呈現在塑件的表面。此種製程所使用之薄膜大致由下列三層結構層所組成：基材、油墨、及耐磨材料。其中該基材係用來承載油墨與耐磨材料，其呈膜狀或片狀，材質可用一般的聚對苯二甲酸乙烯酯(polyethylene terephthalate,PET)或聚碳酸酯(polycarbonate,PC)。上述油墨係用來形成所欲呈現的圖形，或是使塑件呈現金屬、皮革、木紋、石紋等多樣化的產品外觀。耐磨材料則於成型後會位於整體物件的最外面，以提供耐磨、抗刮、抗反射等效果。In-Mold Decoration (IMD) is a popular surface decoration technology, which is mainly used in the surface decoration and functional panels of home appliances, mobile phone window lenses and housings, washing machine consoles, refrigerator consoles, air conditioners. Production of exterior objects such as panels and signs for various home appliances such as Taiwan and automobile dashboards. The technical point of the in-mold decoration is to put a patterned film into the mold for injection molding (Injection Molding). When the plastic part is formed, the patterned film is integrated with the plastic to make the pattern appear on the surface of the plastic part. The film used in such a process consists essentially of the following three structural layers: a substrate, an ink, and a wear resistant material. The substrate is used for carrying ink and wear-resistant materials, and is in the form of a film or a sheet. The material may be a general polyethylene terephthalate (PET) or a polycarbonate (PC). The above inks are used to form the desired pattern, or to give the plastic parts a variety of product appearances such as metal, leather, wood grain, stone grain and the like. The wear-resistant material will be located at the outermost part of the overall object after molding to provide wear resistance, scratch resistance, anti-reflection and the like.
目前業界已利用上述習知的模內裝飾技術來在塑件表面形成印刷式天線，以應用在需要使用天線裝置來傳送與接收訊號的小型或微型裝置上，諸如各種手持式行動裝置、無線家電、或射頻辨識標籤(RFID)等。其作法中僅需將原先模內裝飾技術中使用的彩色漾印油墨改成導電油墨，繼而在薄膜表面印出天線圖形即可。上述印刷式的天線在相關應用中有許多優勢存在，諸如可精確調整天線的諧振頻率、Q值和阻抗等性能參數，以達到天線感應或傳輸所需的目標值；可任意改變天線線圈的形狀、匝數、天線尺寸、及線徑粗細等，以適應業主表面加工的要求；適用在各種不同的習知基材及塑料，其可應用性較柱式天線或繞線式天線為高。At present, the above-mentioned conventional in-mold decoration technology has been used to form a printed antenna on the surface of a plastic part for use in a small or micro device that needs to use an antenna device to transmit and receive signals, such as various handheld mobile devices, wireless home appliances. , or a radio frequency identification tag (RFID), etc. In the method, only the color printing ink used in the original in-mold decoration technology is changed into a conductive ink, and then the antenna pattern is printed on the surface of the film. The above-mentioned printed antenna has many advantages in related applications, such as precisely adjusting the antenna's resonant frequency, Q value and impedance and other performance parameters to achieve the target value required for antenna sensing or transmission; the shape of the antenna coil can be arbitrarily changed , the number of turns, the size of the antenna, and the thickness of the wire diameter to meet the requirements of the surface processing of the owner; applicable to a variety of different conventional substrates and plastics, the applicability is higher than that of the column antenna or the wound antenna.
對於採用上述模內裝飾製程來在塑件表面形成印刷式天線的作法而言，物件中的晶片模組與天線圖形之間的連接是其製造技術中的一大關鍵環節。在習知的印刷式天線技術中，印刷式天線與電路板之間一般多採用導電膠黏合或是直接壓合的方法來建立電性連結。然，此作法在天線圖形被包覆在薄膜與塑件表面之間的場合中係無法實行。對此，目前業界一般會在注塑製程後(即塑件成型後)進行天線圖形與晶片的連結，如透過塑件上預先定義的開口讓天線圖形得以從塑件中裸露而出，再另外拉以導線來建立連結。然，此作法需要額外的連結步驟，且以此作法建立之連結可靠度不佳，其連結結構之設計也將增加塑件整體所需之厚度，不利於現今電子裝置小型化之需求。For the above-described in-mold decoration process to form a printed antenna on the surface of the plastic part, the connection between the wafer module and the antenna pattern in the object is a key link in its manufacturing technology. In the conventional printed antenna technology, a conductive adhesive or a direct press-bonding method is generally used between the printed antenna and the circuit board to establish an electrical connection. However, this is not possible in the case where the antenna pattern is coated between the film and the surface of the plastic part. In this regard, the industry generally generally connects the antenna pattern to the wafer after the injection molding process (ie, after the plastic part is formed), such as through the pre-defined opening on the plastic part, the antenna pattern can be exposed from the plastic part, and then pulled Wires are used to establish the link. However, this method requires an additional joining step, and the connection reliability established by this method is not good, and the design of the connecting structure will also increase the thickness required for the overall plastic part, which is disadvantageous for the miniaturization of electronic devices.
有鑑於上述先前技術的諸多缺失。目前業界亟需改良現有習知的印刷式天線的製作方法，以期降低天線裝置的製作成本與所需步驟，並提供更佳的效能與可靠度。In view of the many shortcomings of the prior art described above. There is an urgent need in the industry to improve the fabrication methods of conventional printed antennas in order to reduce the manufacturing cost and required steps of the antenna device and provide better performance and reliability.
有鑑於上述習知技術之缺失，本發明揭露了一種利用模內成型製程製作的天線裝置及其方法。該天線裝置具有一天線圖形得以黏附方式形成在塑件表面。該天線圖形係與一固定在塑件中的導電件電性耦接，該導電件復以其自該塑件中裸露出之部位與一外部電路產生電性連結。In view of the above-mentioned shortcomings of the prior art, the present invention discloses an antenna device fabricated by an in-mold forming process and a method thereof.

本發明之另一目的在於提供一種新穎的天線製作方法，其係於進行注塑步驟前先將一導電件置於模具中使之與塑件一起成型，成型後該導電件會與塑件表面的天線圖形電性耦接，且該導電件會有部分自塑件中裸露出來。Another object of the present invention is to provide a novel antenna manufacturing method, which is characterized in that a conductive member is placed in a mold to be molded together with the plastic member before the injection molding step, and the conductive member is formed on the surface of the plastic member after molding. The antenna pattern is electrically coupled, and the conductive member is partially exposed from the plastic member.
本發明之優點在於不須在塑件成型後再施以額外的製程步驟來使天線圖形得以與外部電路產生電性連結，並可增進天線裝置與外部電路耦接的可靠性。The invention has the advantages that an additional process step is not required after the molding of the plastic part to electrically connect the antenna pattern with an external circuit, and the reliability of coupling the antenna device to the external circuit can be improved.
本發明之另一優點在於其將導電件與塑件一起成型之作法可減少塑件整體所需之厚度，且該導電件不會在塑件表面造成明顯的突起。Another advantage of the present invention is that it allows the conductive member to be molded with the plastic member to reduce the overall thickness of the plastic member, and the conductive member does not cause significant protrusions on the surface of the plastic member.
在參閱下述詳細的實施方式及相關的圖示與申請專利範圍後，閱者將更能了解本發明其他的目的、特徵、及優點。Other objects, features, and advantages of the present invention will become apparent from the <RTIgt;
本發明揭露了一種利用模內成型製程在一塑件表面形成天線裝置之方法。如第一圖所示，其為根據本發明一實施例一薄膜與其上圖形之俯視圖，並同時參考第八圖所示天線裝置製作之步驟流程圖。首先在方法的第一步驟1001中，在一薄膜100的膜面上印上預先設定的天線圖形101。該天線圖形101係作為天線裝置的傳送端與接收端，如一天線迴圈，其可傳送或接收所欲之電磁訊號。該印製步驟可選擇性地包含印製後續欲呈現在塑件上的裝飾圖形103，如產品的外觀設計圖樣或製造商的標識。薄膜100係用來承載形成上述天線圖形101與裝飾圖形103所需之油墨，其於製程完成後會連同該些圖形黏附在塑件表面上。其中該天線圖形101係以導電油墨(conductive ink)印製而成，以形成具有導電性的薄型化表面天線來傳遞訊號。該裝飾圖形103則以一般的漾印油墨印製成所欲表現的圖樣與色彩，如圖樣標識，或是賦予塑件多樣化的外表與質感。The present invention discloses a method of forming an antenna device on a surface of a plastic part by an in-mold forming process. As shown in the first figure, it is a top view of a film and its upper pattern according to an embodiment of the present invention, and at the same time, referring to the flow chart of the steps of the antenna device shown in FIG. First, in a first step 1001 of the method, a predetermined antenna pattern 101 is printed on the film surface of a film 100. The antenna pattern 101 serves as a transmitting end and a receiving end of the antenna device, such as an antenna loop, which can transmit or receive a desired electromagnetic signal. The printing step can optionally include printing a decorative graphic 103 to be subsequently presented on the plastic article, such as a design of the product or a logo of the manufacturer. The film 100 is used to carry the ink required to form the antenna pattern 101 and the decorative pattern 103, and is adhered to the surface of the plastic part together with the patterns after the process is completed. The antenna pattern 101 is printed with a conductive ink to form a conductive thin surface antenna to transmit signals. The decorative graphic 103 is printed with the general printed ink to form the pattern and color to be expressed, as shown in the figure, or to give the plastic parts a variety of appearance and texture.
由於帶有油墨圖形的薄膜100須具有符合塑件外型的立體形狀以方便適用於後續的射出成型製程，故於本發明方法的第二步驟1002中，完成圖形印製的薄膜100須再經過一道立體成型(3D forming)步驟來將其壓製成預定的薄膜形狀。如第二a～二c圖所示，其描繪出根據本發明一實施例以模具沖壓方式形成立體薄膜100’之示意圖。首先在第二a圖中，一薄膜100上已預先形成有天線圖形101與裝飾圖形103。該帶有天線圖形101與裝飾圖形103的薄膜100會被置入具有預定塑形的沖壓模具105中來進行壓製，如第二b圖所示。藉由上下兩模具的壓合，原先呈平面狀的薄膜100會被壓製成具有所欲塑形的立體薄膜100’。壓製後，原先平面狀薄膜100上的油墨圖形會隨該塑形而變，如第二c圖所示，故初始在天線圖形與裝飾圖形之設計上即須預先考量薄膜立體成型後所帶來的變化。須注意本發明薄膜100的立體成型步驟亦可採行真空、液壓、超高壓等模具沖壓以外的方式來進行。或者，在某些場合中，如塑件上呈現圖樣的部位為一平坦面時，薄膜100亦可能不經過立體成型步驟直接以平面狀形式黏附在塑件上。Since the film 100 with the ink pattern has a three-dimensional shape conforming to the shape of the plastic part to facilitate the subsequent injection molding process, in the second step 1002 of the method of the present invention, the film 100 which has been subjected to the graphic printing must pass through A 3D forming step is used to press it into a predetermined film shape. As shown in the second a to c-c drawings, a schematic view of forming a three-dimensional film 100' by die stamping according to an embodiment of the present invention is depicted. First, in the second a diagram, the antenna pattern 101 and the decorative pattern 103 are formed in advance on a film 100. The film 100 with the antenna pattern 101 and the decorative pattern 103 is placed in a stamping die 105 having a predetermined shape for pressing, as shown in the second b. The film 100, which was originally planar, is pressed into a three-dimensional film 100' having a desired shape by press-fitting of the upper and lower molds. After pressing, the ink pattern on the original planar film 100 will change according to the shape, as shown in the second c. Therefore, the initial design of the antenna pattern and the decorative pattern must be considered in advance after the film is three-dimensionally formed. The change. It should be noted that the three-dimensional molding step of the film 100 of the present invention can also be carried out in a manner other than vacuum stamping such as vacuum, hydraulic pressure, or ultrahigh pressure. Alternatively, in some cases, if the portion on the plastic part that presents the pattern is a flat surface, the film 100 may also adhere directly to the plastic part in a planar form without a three-dimensional forming step.
在完成呈立體形狀的薄膜100’後，之後薄膜100’會進行切邊(trimming)步驟1003來切除薄膜100’周緣多餘的部分，如第三圖所示。切邊步驟會切除掉的部分係視實際薄膜100’所要黏附的外型與範圍而定，其可採用沖切等方式來達成。經過切邊步驟後，帶有油墨圖形的立體薄膜100’才算製作完成。該薄膜100’可藉由之後的注塑步驟緊密黏附在所形成塑件的表面上。須注意上述薄膜圖示僅為呈具之用，並非按實際比例所繪製。圖式中的某些部分因為說明之故可能會被放大強調。After completion of the three-dimensionally shaped film 100', the film 100' is then subjected to a trimming step 1003 to remove excess portions of the periphery of the film 100', as shown in the third figure. The portion to be cut off by the trimming step depends on the shape and extent to which the actual film 100' is to be adhered, which can be achieved by punching or the like. After the trimming step, the three-dimensional film 100' with the ink pattern is completed. The film 100' can be closely adhered to the surface of the formed plastic part by a subsequent injection molding step. It should be noted that the above film illustrations are for presentation only and are not drawn to scale. Some parts of the diagram may be magnified by the explanation.
在進行最後的射出成型(即注塑)步驟1004前，如第四圖所示，薄膜100’會先放在吻合其外型的其中一上模具107a上。圖中上模具107a與下模具107b對合後中間的中空部位109即為注塑步驟所欲形成之塑件形狀。然，為了使薄膜100’上的天線圖形101在與塑件黏合後得以與其他外部電路耦接，本發明方法在進行射出成型前會先於中空部位109中置入一導電件111來與薄膜100’一起進行注塑製程。該導電件111係設置在能與薄膜100’上的天線圖形101耦接的位置，且部分的該導電件111會與下模具107b接觸。Prior to the final injection molding (i.e., injection molding) step 1004, as shown in the fourth figure, the film 100' will first be placed on one of the upper molds 107a that conforms to its outer shape. The hollow portion 109 in the middle of the upper mold 107a and the lower mold 107b in the drawing is the shape of the plastic part to be formed in the injection molding step. However, in order to enable the antenna pattern 101 on the film 100' to be coupled to other external circuits after being bonded to the plastic member, the method of the present invention places a conductive member 111 and a film in the hollow portion 109 before the injection molding. 100' together with the injection molding process. The conductive member 111 is disposed at a position that can be coupled to the antenna pattern 101 on the film 100', and a portion of the conductive member 111 is in contact with the lower mold 107b.
於射出成型步驟1004中，塑料會從模具上的注入口113注入中空部位109中，成型期間塑料會充滿整個中空部位109並與模具上的薄膜100’黏合。如此，如第五圖所示，當塑件115成型脫膜後，薄膜100’與其上的天線圖形101與裝飾圖形103皆會黏附在塑件115上並與之成為一體。該導電件111有部分會位於該塑件115中並與塑件115表面的天線圖形101耦接，而另一部分則會從塑件115的另一面裸露而出，其於後續實施例中有進一步詳細的描述。In the injection molding step 1004, plastic is injected into the hollow portion 109 from the injection port 113 on the mold, during which the plastic fills the entire hollow portion 109 and adheres to the film 100' on the mold. Thus, as shown in the fifth figure, after the plastic member 115 is formed and released, the film 100' and the antenna pattern 101 and the decorative pattern 103 thereon are adhered to and integrated with the plastic member 115. The conductive member 111 is partially located in the plastic member 115 and coupled to the antenna pattern 101 on the surface of the plastic member 115, and the other portion is exposed from the other surface of the plastic member 115, which is further developed in the subsequent embodiment. Detailed description.
現在請參照第六圖，其描繪出根據本發明實施例一天線裝置的細部結構圖。如圖所示，本發明之天線裝置係以天線圖形101為主，如天線迴路結構，其係利用導電油墨於注塑形成塑件前先印製形成在薄膜100’上，薄膜100’上亦可能會印製上欲形成在塑件表面的裝飾圖形103。於注塑步驟後，薄膜100’及其上所印製的天線圖形101與裝飾圖形103會因為注塑帶來的熱壓效果黏合在所形成的塑件115上。在一實施例中，該薄膜100’可為一透明保護膜，其上所印製的裝飾圖形103會隨著注塑步驟轉附到塑件115的外表面上，賦予塑件多樣化的外表與質感。而薄膜100’則同時作為塑件115表面的保護層，保護其內的天線圖形101與裝飾圖形103不受外界損傷。在本發明實施例中，薄膜100’的材質包含但不限定於聚碳酸酯(polycarbonate,PC)、聚對苯二甲酸乙烯酯(polyethylene terephthalate,PET)。注塑製程中所用塑件之材質包含聚碳酸酯(polycarbonate,PC)、丙烯腈-丁二烯-苯乙烯共聚物(acrylonitrile-butadiene-styrene copolymers ABS)、熱塑性聚胺基甲酸酯(thermoplastic polyurethane,TPU)、聚甲基丙烯酸甲酯(Poly methyl methacrylate,PMMA)、聚對苯二甲酸丁二酯(Polybutylene Terephthalate,PBT)或其組合。Referring now to the sixth drawing, a detailed structural view of an antenna device according to an embodiment of the present invention is depicted. As shown in the figure, the antenna device of the present invention is mainly composed of an antenna pattern 101, such as an antenna circuit structure, which is formed on the film 100' by using a conductive ink before injection molding to form a plastic part, and the film 100' may also be formed. A decorative graphic 103 to be formed on the surface of the plastic part is printed. After the injection molding step, the film 100' and the antenna pattern 101 and the decorative pattern 103 printed thereon are adhered to the formed plastic member 115 by the hot pressing effect by injection molding. In one embodiment, the film 100' can be a transparent protective film, and the decorative pattern 103 printed thereon is attached to the outer surface of the plastic part 115 along with the injection molding step, giving the plastic part a variety of appearances and Texture. The film 100' serves as a protective layer on the surface of the plastic member 115, and protects the antenna pattern 101 and the decorative pattern 103 therein from external damage. In the embodiment of the present invention, the material of the film 100' includes, but is not limited to, polycarbonate (PC), polyethylene terephthalate (PET). The plastic parts used in the injection molding process include polycarbonate (PC), acrylonitrile-butadiene-styrene copolymers (ABS), thermoplastic polyurethane (thermoplastic polyurethane, TPU), polymethyl methacrylate (PMMA), polybutylene terephthalate (PBT) or a combination thereof.
另一方面，導電件111係於進行注塑步驟前置入模具中與塑件115一起成型。在本發明一較佳實施例中，請同時參照第七a-c圖，其顯示根據本發明較佳實施例中導電件111之主要結構。如圖所示，本發明之導電件111具有一耦接部111a與一接觸部111b。耦接部111a一端與接觸部111b一端連接，另一端則為一耦接端111c，該耦接端111c自耦接部向上翹曲並朝遠離該接觸部方向延伸，其係與天線圖形電性耦接。接觸部111b則為一基座平面，其係與一外部電路電性連接。該耦接部111a與接觸部111b係設計呈一夾角α，使得該耦接部111a上的耦接端111c與接觸部111b之間有一預定間距d存在。該間距d係使導電件111的耦接端111c於射出成型後會與天線圖形101電性耦接，不會在塑件115表面造成過度突兀。而導電件111則會被固定在塑件115上，其部分的接觸部111b會從塑件115的另一面裸露出。故此，間距d的大小會影響到耦接部111a與天線圖形101的耦接以及接觸部111b的裸露，其須視塑件115與天線圖形101厚度精準地設定。在本發明之更佳實施例中，接觸部之尺寸係為2.96mm×2.46mm的微型化尺寸，該耦接部111a與接觸部111b所呈之夾角α則在28°～32°間，而該間距d則在1.37mm～1.57mm間，以應用在手持式或行動式等輕薄短小的電子裝置中。On the other hand, the conductive member 111 is molded into the mold together with the plastic member 115 before being subjected to the injection molding step. In a preferred embodiment of the present invention, reference is made to the seventh a-c diagram, which shows the main structure of the conductive member 111 in accordance with a preferred embodiment of the present invention. As shown, the conductive member 111 of the present invention has a coupling portion 111a and a contact portion 111b. One end of the coupling portion 111a is connected to one end of the contact portion 111b, and the other end is a coupling end 111c. The coupling end 111c is warped upward from the coupling portion and extends away from the contact portion, and the antenna pattern and the antenna pattern are electrically connected. Coupling. The contact portion 111b is a pedestal plane that is electrically connected to an external circuit. The coupling portion 111a and the contact portion 111b are designed to have an angle α such that a predetermined distance d between the coupling end 111c and the contact portion 111b on the coupling portion 111a exists. The spacing d is such that the coupling end 111c of the conductive member 111 is electrically coupled to the antenna pattern 101 after injection molding, and does not cause excessive abruptness on the surface of the plastic member 115. The conductive member 111 is fixed to the plastic member 115, and a part of the contact portion 111b is exposed from the other surface of the plastic member 115. Therefore, the size of the pitch d affects the coupling of the coupling portion 111a and the antenna pattern 101 and the exposure of the contact portion 111b, which are precisely set according to the thickness of the plastic member 115 and the antenna pattern 101. In a further preferred embodiment of the present invention, the size of the contact portion is 2.96 mm × 2.46 mm, and the angle α between the coupling portion 111a and the contact portion 111b is between 28° and 32°. The spacing d is between 1.37 mm and 1.57 mm for use in thin, short electronic devices such as hand-held or mobile.
如本發明一實作中，塑件115可為一手機背蓋，該手機所欲呈現的彩色圖樣及表面天線元件(即天線圖形)可藉由本發明上述注塑製程形成在該手機背蓋上。在本實作中，上述導電件111的接觸部111b可為一接墊(contact pad)。該接墊可從手機背蓋的內面裸露而出，進而與設置在手機機殼內的電路板117電性耦接，如第六圖中接觸部111b的裸露面與其下方電路板117的彈簧件119接觸。故以此方式，手機背蓋上的表面天線元件可經由導電件與手機內部的電路板電性連接以接收或傳送訊號。In an implementation of the present invention, the plastic part 115 can be a back cover of a mobile phone, and the color pattern and the surface antenna element (ie, the antenna pattern) to be presented by the mobile phone can be formed on the back cover of the mobile phone by the above-mentioned injection molding process of the present invention. In this implementation, the contact portion 111b of the conductive member 111 may be a contact pad. The pad can be exposed from the inner surface of the back cover of the mobile phone, and is electrically coupled to the circuit board 117 disposed in the casing of the mobile phone, such as the exposed surface of the contact portion 111b and the spring of the circuit board 117 below thereof in the sixth figure. Piece 119 is in contact. Therefore, in this manner, the surface antenna element on the back cover of the mobile phone can be electrically connected to the circuit board inside the mobile phone via the conductive member to receive or transmit the signal.
本發明之天線製作方法可改進一般習知技術中以注塑製程形成天線裝置的方法之缺失。發明中採用在射出成型形成塑件前預先置入一導電件之方式來使包覆在薄膜與塑件表面間的天線裝置可與一外部電路產生電性連結，不須於塑件成形後再施以額外的步驟來使天線裝置與外部電路耦接。本發明之方法除了可減少製程步驟外，同時可增進天線裝置與外部電路耦接的可靠性，其結構之設計亦可減少塑件整體所需之厚度，且不會在塑件表面形成明顯的突起，實為一具新穎性與進步性的發明。The antenna fabrication method of the present invention can improve the lack of a conventional art technique for forming an antenna device by an injection molding process. In the invention, a conductive member is preliminarily placed in the injection molding to form a conductive member, so that the antenna device coated between the film and the surface of the plastic member can be electrically connected to an external circuit, without forming the plastic member. Additional steps are taken to couple the antenna device to an external circuit. The method of the invention not only reduces the process steps, but also improves the reliability of coupling of the antenna device and the external circuit, and the structure design thereof can also reduce the thickness required for the whole plastic part, and does not form obvious on the surface of the plastic part. Protrusion is a novel and progressive invention.
