一般行動電話或平板電腦上通常會設有攝像鏡頭,其主要包括一鏡頭單元以及用以驅動該鏡頭單元之一鏡頭驅動機構(例如音圈馬達(Voice Coil Motor,VCM)),在上述鏡頭驅動機構中大多設有由磁鐵和線圈所組成的驅動組件,藉此可驅使容置於鏡頭驅動機構中之鏡頭單元沿其光軸方向移動,進而達到自動對焦之效果。 A general-purpose mobile phone or tablet usually has a camera lens, which mainly includes a lens unit and a lens driving mechanism (such as a voice coil motor (VCM)) for driving the lens unit. Most of the mechanisms are provided with a driving assembly composed of a magnet and a coil, thereby driving the lens unit accommodated in the lens driving mechanism to move along the optical axis direction, thereby achieving the effect of autofocus.
請參閱第1A、1B圖,其中第1A圖表示一習知音圈馬達10連接一透明板G和一電路板P的示意圖,第1B圖則表示沿第1A圖中A-A線段的剖視圖。由第1A、1B圖中可以看出音圈馬達10之一外框11與底座13結合,一鏡頭承載件12設置於由外框11和底座13所形成的容納空間101內,一上簧片S1連接外框11和鏡頭承載件12,且一下簧片S2連接底座13和鏡頭承載件12,如此一來鏡頭承載件12和容置於其中的鏡頭單元(未圖示)便可透過音圈馬達10帶動而相對於外框11和底座13沿著其光軸方向移動。此外,透明板G係貼附於外框11之頂面111,藉以保護鏡頭驅動機構10內部的鏡頭單元和其他零件,同時可允許外部光線透過透明板G而進 入到音圈馬達10內部。 Please refer to FIGS. 1A and 1B, wherein FIG. 1A shows a schematic diagram of a conventional voice coil motor 10 connected to a transparent plate G and a circuit board P, and FIG. 1B shows a cross-sectional view taken along line A-A of FIG. 1A. It can be seen from the drawings 1A and 1B that an outer frame 11 of the voice coil motor 10 is coupled with the base 13, and a lens carrier 12 is disposed in the accommodating space 101 formed by the outer frame 11 and the base 13, and an upper reed S1 connects the outer frame 11 and the lens carrier 12, and the lower reed S2 connects the base 13 and the lens carrier 12, so that the lens carrier 12 and the lens unit (not shown) accommodated therein can pass through the voice coil. The motor 10 is moved to move in the optical axis direction with respect to the outer frame 11 and the base 13. In addition, the transparent plate G is attached to the top surface 111 of the outer frame 11 to protect the lens unit and other parts inside the lens driving mechanism 10, and allows external light to pass through the transparent plate G. It enters the inside of the voice coil motor 10.
然而,由於音圈馬達10的外框11大多是以具導磁性的金屬板沖壓而成,且有鑑於可攜式電子裝置的體積越來越小,因此電子裝置內部的通訊元件(例如天線或無線通訊晶片)容易受到金屬外框11的影響而使其效能降低;另一方面,由於前述上簧片S1係呈平板狀,為了使上簧片S1能夠順利連接外框11與鏡頭承載件12,通常會在金屬外框11的四個角落處形成凹陷結構112(如第1A、1B圖所示),以利於上簧片S1與鏡頭承載件12的上表面和凹陷結構112之下表面(第1B圖)相連接,惟如此將使得外框21的頂面111和透明板G之間的貼合面積變小,以致於影響組裝後的整體結構強度。 However, since the outer frame 11 of the voice coil motor 10 is mostly stamped with a magnetically conductive metal plate, and in view of the smaller and smaller size of the portable electronic device, the communication components inside the electronic device (such as an antenna or The wireless communication chip is easily affected by the metal frame 11 to reduce its performance. On the other hand, since the upper reed S1 has a flat shape, the upper frame 11 and the lens carrier 12 can be smoothly connected in order to enable the upper reed S1 to be smoothly connected. A recessed structure 112 (as shown in FIGS. 1A and 1B) is generally formed at four corners of the metal bezel 11 to facilitate the upper surface of the upper reed S1 and the lens carrier 12 and the lower surface of the recessed structure 112 ( Fig. 1B is connected, but this will make the bonding area between the top surface 111 of the outer frame 21 and the transparent plate G small, so as to affect the overall structural strength after assembly.

The four side faces 212 of the outer frame 21 extend from the edge of the top surface 211 toward the base 23, and the base 23 and the outer frame 21 are fixedly coupled with each other. The carrier 22 is movably disposed between the outer frame 21 and the base 23, wherein the lens carrier 22 has a through hole 220 for receiving and carrying the lens unit (not shown). It should be understood that external light can enter the lens driving mechanism 20 through the opening 210 of the outer frame 21, and sequentially pass through the lens unit in the center of the lens carrier 22 and the lower base 23, and finally project to an image sensing unit.

It should be noted that the first magnetic element M may also be a coil, and the second magnetic element C may be a single pole or a multi-pole magnet, so that the effect of controlling the movement of the lens unit by magnetic force can also be achieved.
再請一併參閱第2、3A、3B圖,其中第3A圖表示第2圖中之鏡頭驅動機構20與一透明板G和電路板P結合的示意圖,第3B圖則表示沿第3A圖中B-B線段的剖視圖。由第3A圖中可以看出, 組裝後的鏡頭驅動機構20可與一塑膠或玻璃材質之透明板G結合,其中透明板G係貼附於外框21上方平坦之頂面211,藉此可保護鏡頭驅動機構20內部的鏡頭單元和其他零件,同時亦可允許外部光線透過透明板G而進入到鏡頭驅動機構20內部,以利於透過影像感測單元(例如CCD)將所接收到之光線轉換為電子訊號,其中鏡頭驅動機構20可透過與其結合之電路板P而電性連接到一外部電源,或者可藉由電路板P將電子訊號傳送到鏡頭驅動機構20外部的處理器以進行資料運算。 Please refer to FIG. 2, FIG. 3A and FIG. 3B together, wherein FIG. 3A shows a schematic diagram of the lens driving mechanism 20 in FIG. 2 combined with a transparent plate G and a circuit board P, and FIG. 3B shows the image along the third embodiment. A cross-sectional view of the BB line segment. As can be seen from Figure 3A, The assembled lens driving mechanism 20 can be combined with a plastic or glass transparent plate G, wherein the transparent plate G is attached to the flat top surface 211 above the outer frame 21, thereby protecting the lens unit inside the lens driving mechanism 20.

再請一併參閱第2、3B圖,由圖中可以看出鏡頭承載件22以及上、下簧片S1、S2皆是設置於外框21和底座23所形成的容納空間201內,其中上簧片S1連接外框21和鏡頭承載件22,下簧片S2則連接底座23和鏡頭承載件22。需特別說明的是,由於本實施例中之外框21含有塑膠材質(例如可完全由塑膠材質所構成,或可在塑膠材料中摻入金屬粉末),因此可利用射出成形或嵌入成形(Insert Molding)等一體成形的方式製作,其中更可於外框21成形時直接在外框21的內側表面上形成凸塊213(第3B圖),且前述凸塊213的位置係對應於外框21之四邊形頂面211與側面212的鄰接處,如此一來不僅可在外框21上方形成大面積且平坦的四邊形頂面211,以提升外框21和透明板G的貼合面積並強化兩者間的固定效果,同時透過在外框21之頂面211與側面212的鄰接處附近形成凸塊213,更可大幅提升外框21的整體結構強度。 Referring to FIG. 2 and FIG. 3B together, it can be seen that the lens carrier 22 and the upper and lower reeds S1 and S2 are disposed in the accommodating space 201 formed by the outer frame 21 and the base 23, wherein The reed S1 connects the outer frame 21 and the lens carrier 22, and the lower reed S2 connects the base 23 and the lens carrier 22. In particular, since the outer frame 21 of the present embodiment contains a plastic material (for example, it can be entirely made of a plastic material, or a metal powder can be incorporated into the plastic material), injection molding or insert molding can be utilized (Insert) Molding or the like is formed in an integrally formed manner, wherein the protrusion 213 (FIG. 3B) is formed directly on the inner side surface of the outer frame 21 when the outer frame 21 is formed, and the position of the aforementioned protrusion 213 corresponds to the outer frame 21 The adjoining portion of the quadrangular top surface 211 and the side surface 212 can form a large-area and flat quadrilateral top surface 211 over the outer frame 21 to enhance the bonding area of the outer frame 21 and the transparent plate G and strengthen the bonding between the two. The fixing effect is achieved by forming the bumps 213 in the vicinity of the abutting portion of the top surface 211 of the outer frame 21 and the side surface 212, and the overall structural strength of the outer frame 21 can be greatly improved.
或者,也可以透過在塑膠材料中摻雜金屬粉粒的方式製作前述外框21,相較於以純塑膠材料製作的方式而言不僅能夠增加機構內部的磁場強度,且相較於傳統的純金屬板壓製的方 式而言則更能提升其結構強度。另一方面,由於外框21具有塑膠材料且可透過一體成形的方式製作,因此可將導線以以模塑互連器件(Molded Interconnect Device,MID)技術(例如雷射直接成形法(Laser Direct Structuring,LDS))直接形成於外框21上,此時可不必額外設置電路元件(如第3A圖中之電路板P)來與外部電路連接,且能大幅縮小鏡頭驅動機構20的整體尺寸並降低製造成本。 Alternatively, the outer frame 21 may be formed by doping metal particles into the plastic material, which not only increases the magnetic field strength inside the mechanism, but also compares with the conventional pure metal. Plate pressing In terms of formula, it can improve its structural strength. On the other hand, since the outer frame 21 has a plastic material and can be fabricated by integral molding, the wires can be fabricated by Molded Interconnect Device (MID) technology (for example, Laser Direct Structuring). , LDS)) is formed directly on the outer frame 21, and it is not necessary to additionally provide a circuit component (such as the circuit board P in FIG. 3A) to be connected to the external circuit, and the overall size of the lens driving mechanism 20 can be greatly reduced and reduced. manufacturing cost.
