Description
本發明係有關於一種含有塑膠透鏡的成像透鏡組及成像鏡頭模組,且特別是有關於一種應用在可攜式電子裝置上的成像透鏡組及成像鏡頭模組。 The present invention relates to an imaging lens assembly and an imaging lens module including a plastic lens, and more particularly to an imaging lens assembly and an imaging lens module for use in a portable electronic device.
近年來,可攜式電子裝置發展快速,例如智慧型電子裝置、平板電腦等,已充斥在現代人的生活中,而裝載在可攜式電子裝置上的鏡頭模組也隨之蓬勃發展。但隨著科技愈來愈進步,使用者對於鏡頭模組的品質要求也愈來愈高,因此鏡頭模組除了在光學設計上的品質提升外,在製造組裝精密度也需提升。 In recent years, portable electronic devices have developed rapidly. For example, smart electronic devices and tablet computers have been filled in the lives of modern people, and the lens modules mounted on portable electronic devices have also prospered. However, as technology advances, the quality requirements of the lens module are becoming higher and higher. Therefore, in addition to the improvement in optical design, the lens module needs to be improved in manufacturing precision.
配合第14圖,第14圖係繪示一習知成像鏡頭模組6000的剖面示意圖。由第14圖可知,成像鏡頭模組包含一塑膠鏡筒6100、一光學鏡片組6200以及至少一遮光片6300,其中光學鏡片組6200包含透鏡6210、透鏡6220、透鏡6230、透鏡6240與透鏡6250。透鏡6210、透鏡6220、 透鏡6230、透鏡6240與透鏡6250均設置於塑膠鏡筒6100內,且遮光片6300係設置於透鏡6230與透鏡6240之間。隨著需要畫素提高,如透鏡6220、透鏡6230、透鏡6240間的外徑差距逐漸遞增,且遮光片6300的需求厚度越來越薄。然而,基於成像鏡頭模組的組裝限制,仍舊只能將遮光片6300夾靠在相鄰的透鏡6230與透鏡6240間,而缺乏可以分擔遮光片6300所承受之擠壓力的設計。因此,在組裝過程中受到不正常擠壓的遮光片便會產生翹曲,使其中心開孔呈現波浪狀翹曲的情形,亦可稱為應力歪曲(Deflection)。對於日益嚴苛的照相品質來說,如此微小的扭曲情形會影響高畫素鏡頭實際拍攝強光源時的影像品質,使拍攝大亮度物體的成像低於預期。 14 is a cross-sectional view of a conventional imaging lens module 6000. As can be seen from FIG. 14, the imaging lens module includes a plastic lens barrel 6100, an optical lens group 6200, and at least one light shielding sheet 6300. The optical lens group 6200 includes a lens 6210, a lens 6220, a lens 6230, a lens 6240, and a lens 6250. The lens 6210, the lens 6220, the lens 6230, the lens 6240, and the lens 6250 are all disposed in the plastic lens barrel 6100, and the light shielding sheet 6300 is disposed between the lens 6230 and the lens 6240. As the pixel size is increased, the difference in outer diameter between the lens 6220, the lens 6230, and the lens 6240 is gradually increased, and the required thickness of the light shielding sheet 6300 is getting thinner and thinner. However, based on the assembly limitation of the imaging lens module, the light shielding sheet 6300 can only be clamped between the adjacent lens 6230 and the lens 6240, and lacks a design that can share the pressing force of the light shielding sheet 6300. Therefore, the light-shielding sheet which is abnormally squeezed during the assembly process will be warped, and the center opening will be undulated, which may also be called Deflection. For increasingly harsh photographic quality, such a small distortion can affect the image quality of a high-resolution lens when shooting a strong light source, making imaging of large-brightness objects lower than expected.

Therefore, the use of the plastic lens can generally reduce the production cost of the imaging lens module, and the use of the light shielding film can shield unnecessary light inside the imaging lens module.
在本發明中,前述三塑膠透鏡沿成像透鏡組的 一中心軸由物側至像側依序為一第一透鏡、一第二透鏡及一第三透鏡。具體地,第一透鏡包含一第一平直承靠部與一第一圓錐面,其中第一平直承靠部位於第一透鏡之像側表面,而第一圓錐面位於第一透鏡之像側表面,且第一圓錐面較第一平直承靠部靠近中心軸。第二透鏡包含一第二平直承靠部、一第二圓錐面、一第四平直承靠面與一第四圓錐面。第二平直承靠部位於第二透鏡之物側表面,第二圓錐面位於第二透鏡之物側表面,且第二圓錐面較第二平直承靠部靠近中心軸。第四平直承靠部位於第二透鏡之像側表面,第四圓錐面位於第二透鏡之像側表面,且第四圓錐面較第四平直承靠部遠離中心軸。第三透鏡包含一第三平直承靠部及一第三圓錐面,其中第三平直承靠部位於第三透鏡之物側表面,第三圓錐面位於第三透鏡之物側表面,且第三圓錐面較第三平直承靠部遠離中心軸。再者,遮光片具體地可設置於第二透鏡與第三透鏡之間並更包含一外徑面,其中外徑面連接遮光片之物側表面與像側表面並與中心開孔同軸。 In the present invention, the three plastic lenses are sequentially a first lens, a second lens and a third lens from the object side to the image side along a central axis of the imaging lens group. Specifically, the first lens includes a first flat bearing portion and a first conical surface, wherein the first flat bearing portion is located on the image side surface of the first lens, and the first conical surface is located on the image of the first lens a side surface, and the first conical surface is closer to the central axis than the first flat abutment. The second lens includes a second flat bearing portion, a second conical surface, a fourth flat bearing surface and a fourth conical surface. The second flat bearing portion is located on the object side surface of the second lens, the second conical surface is located on the object side surface of the second lens, and the second conical surface is closer to the central axis than the second flat bearing portion. The fourth flat bearing portion is located on the image side surface of the second lens, the fourth conical surface is located on the image side surface of the second lens, and the fourth conical surface is away from the central axis than the fourth flat bearing portion. The third lens includes a third flat bearing portion and a third conical surface, wherein the third flat bearing portion is located on the object side surface of the third lens, and the third conical surface is located on the object side surface of the third lens, and The third conical surface is away from the central axis than the third straight abutment. Furthermore, the light shielding sheet may be disposed between the second lens and the third lens and further include an outer diameter surface, wherein the outer diameter surface is connected to the object side surface and the image side surface of the light shielding sheet and is coaxial with the central opening.
具體地,第一平直承靠部可與第二平直承靠部重疊,第一圓錐面可與第二圓錐面接觸,且第三圓錐面可與第四圓錐面接觸。此外,遮光片之物側表面可與第四平直承靠部重疊,而遮光片之像側表面可與第三平直承靠部重疊。第四圓錐面之最小直徑為ψ4,第二圓錐面之最大直徑為ψ2,其滿足下列條件:0.13mm<(ψ4-ψ2)/2<1.20mm。 Specifically, the first straight abutting portion may overlap with the second straight abutting portion, the first conical surface may be in contact with the second conical surface, and the third conical surface may be in contact with the fourth conical surface. Further, the object side surface of the light shielding sheet may overlap with the fourth straight bearing portion, and the image side surface of the light shielding sheet may overlap with the third straight bearing portion. The minimum diameter of the fourth conical surface is ψ4, and the maximum diameter of the second conical surface is ψ2, which satisfies the following condition: 0.13 mm < (ψ4-ψ2)/2<1.20 mm.
因此,經由第一圓錐面與第二圓錐面之間的接觸以及第一平直承靠部與第二平直承靠部之間的重疊,可在 第一透鏡與第二透鏡之間組成一第一軸向連接結構,以組裝第一透鏡與第二透鏡並對正成像透鏡組的中心軸。而第四圓錐面與第三圓錐面之間的接觸以及遮光片之物側表面與像側表面分別與第四平直承靠部、第三平直承靠部之間的重疊可進一步組成一第二軸向連接結構,以組裝第二透鏡與第三透鏡並對正成像透鏡組的中心軸。也就是說,本發明可藉由第一軸向連接結構與第二軸向連接結構的設計使外徑差距大的透鏡間可以互相對正,以提升組裝時的精準度。 Therefore, a contact between the first lens and the second lens can be formed by the contact between the first conical surface and the second conical surface and the overlap between the first flat bearing portion and the second flat bearing portion The first axial connection structure is to assemble the first lens and the second lens and to image the central axis of the lens group. The contact between the fourth conical surface and the third conical surface and the overlap between the object side surface and the image side surface of the light shielding sheet and the fourth flat bearing portion and the third flat bearing portion respectively can further form a The second axial connection structure is to assemble the second lens and the third lens and to image the central axis of the lens group. That is to say, according to the design of the first axial connection structure and the second axial connection structure, the lenses of the outer diameter difference can be aligned with each other to improve the precision during assembly.
更進一步來說,本發明中第一圓錐面與第二圓錐面可用以相互組裝並對正中心軸,而第四圓錐面與第三圓錐面亦可用以互相組裝並對正中心軸。藉此,由於圓錐面的尺寸精度較易控管,故使用圓錐面來進行組裝將有利於量產。此外,第四圓錐面之最小直徑以及第二圓錐面之最大直徑可進一步滿足下列條件:0.18mm<(ψ4-ψ2)/2<0.85mm。藉此,可更明確地定義出圓錐面的位置,進而避免在以塑膠成形製程製造前述複數個塑膠透鏡時可能衍生的射出不良問題。此外,本發明中第一透鏡之第一圓錐面的直徑係由其像側表面往物側表面漸縮,而第二透鏡之第二圓錐面與第四圓錐面以及第三透鏡之第三圓錐面中每一者的直徑亦是由其像側表面往物側表面漸縮,但本發明不以此為限。 Furthermore, in the present invention, the first conical surface and the second conical surface may be assembled to each other and to the positive central axis, and the fourth conical surface and the third conical surface may also be used to assemble each other and to the positive central axis. Thereby, since the dimensional accuracy of the conical surface is easier to control, the use of the conical surface for assembly will facilitate mass production. Further, the minimum diameter of the fourth conical surface and the maximum diameter of the second conical surface may further satisfy the following conditions: 0.18 mm < (ψ4-ψ2)/2 < 0.85 mm. Thereby, the position of the conical surface can be more clearly defined, thereby avoiding the problem of poor ejection which may be caused when the plurality of plastic lenses are manufactured by the plastic forming process. In addition, in the present invention, the diameter of the first conical surface of the first lens is tapered by the image side surface toward the object side surface, and the second conical surface of the second lens and the fourth conical surface and the third conical surface of the third lens The diameter of each of the faces is also tapered by the image side surface toward the object side surface, but the invention is not limited thereto.
在本發明中,前述遮光片之外徑面的直徑為D,第四圓錐面之最小直徑為ψ4,其可滿足下列條件:|ψ4-D|/20.05mm。藉此,由於前述兩者的差值不大,可避免遮光片過度傾斜,進而影響遮光效率。再者,當遮光 片之外徑面的直徑為D,第四圓錐面之最小直徑為ψ4,且第二圓錐面之最大直徑為ψ2時,可滿足下列條件:0.6<(π^2)×((ψ4-ψ2)/D)<3.6。藉此,可增加容納遮光片的空間,以遮蔽更多可能來自第二圓錐面的雜散光。較佳地,遮光片之外徑面的直徑、第四圓錐面之最小直徑以及第二圓錐面之最大直徑更可進一步滿足下列條件:0.82<(π^2)×((ψ4-ψ2)/D)<2.9,以提供較佳的遮蔽範圍。此外,當遮光片之中心開孔的最小內徑為ψi,遮光片之外徑面的直徑為D,其可滿足下列條件:0.4<ψi/D<0.76。藉此,可避免中心開孔過大的遮光片影響成像品質,而中心開孔過小的遮光片影響鏡頭規格。 In the present invention, the diameter of the outer diameter surface of the light shielding sheet is D, and the minimum diameter of the fourth conical surface is ψ4, which satisfies the following conditions: |ψ4-D|/2 0.05mm. Thereby, since the difference between the two is small, it is possible to avoid excessive tilting of the light shielding sheet, thereby affecting the light shielding efficiency. Furthermore, when the diameter of the outer diameter surface of the light shielding sheet is D, the minimum diameter of the fourth conical surface is ψ4, and the maximum diameter of the second conical surface is ψ2, the following conditions can be satisfied: 0.6 < (π^2) × ((ψ4-ψ2)/D)<3.6. Thereby, the space for accommodating the light shielding sheet can be increased to shield more stray light which may come from the second conical surface. Preferably, the diameter of the outer diameter surface of the light shielding sheet, the minimum diameter of the fourth conical surface, and the maximum diameter of the second conical surface further satisfy the following conditions: 0.82 < (π^2) × ((ψ4-ψ2)/ D) < 2.9 to provide a better coverage range. Further, when the minimum inner diameter of the central opening of the light shielding sheet is ψi, the diameter of the outer diameter surface of the light shielding sheet is D, which satisfies the following condition: 0.4 < ψi / D < 0.76. Thereby, it is possible to prevent the light shielding sheet having an excessive opening in the center from affecting the image quality, and the light shielding sheet having a small opening in the center affects the lens size.
在本發明中,第二圓錐面與中心軸之一夾角為α1並與第一圓錐面與中心軸之一夾角互相對應,且其滿足下列條件:3度<α1<42度。第四圓錐面與中心軸的夾角為α2並與第三圓錐面與中心軸之一夾角互相對應,且其可滿足下列條件:3度<α2<42度。藉此,適當圓錐面夾角的設計,可大幅增加量產的可行性。再者,第四圓錐面與中心軸的夾角更可滿足下列條件:13度<α2<33度。因此,藉由合適的圓錐面夾角的設計,可避免單一鏡片本身圓錐面的真圓度(Roundness)影響透鏡間組合的密合度。同理,第二圓錐面與中心軸之夾角亦可滿足下列條件:13度<α1<33度。 In the present invention, the angle between the second conical surface and one of the central axes is α1 and corresponds to an angle between the first conical surface and the central axis, and it satisfies the following condition: 3 degrees < α1 < 42 degrees. The angle between the fourth conical surface and the central axis is α2 and corresponds to an angle between the third conical surface and the central axis, and it can satisfy the following conditions: 3 degrees < α2 < 42 degrees. Thereby, the design of the appropriate conical surface angle can greatly increase the feasibility of mass production. Furthermore, the angle between the fourth conical surface and the central axis can satisfy the following conditions: 13 degrees < α2 < 33 degrees. Therefore, by the design of the angle of the conical surface, the roundness of the conical surface of the single lens itself can be prevented from affecting the tightness of the combination between the lenses. Similarly, the angle between the second conical surface and the central axis can also satisfy the following conditions: 13 degrees < α1 < 33 degrees.
在本發明中,第一透鏡之外徑為D1,第二透鏡之外徑為D2,第四圓錐面之最小直徑為ψ4,其可滿足下列 條件:D1ψ4<D2。藉此,前述成像透鏡組可適用更大光圈的光學設計系統。此外,第一透鏡之外徑為D1,第四圓錐面之最小直徑為ψ4,其可滿足下列條件:0.9<ψ4/D1<1.35。藉此,可使多片數的透鏡皆可藉由圓錐面對正相鄰透鏡的中心,降低傳統組裝公差的影響。更具體地,第一透鏡之外徑與第四圓錐面之最小直徑可滿足下列條件:0.94<ψ4/D1<1.15。藉此,可降低同一機種鏡頭間的品質差異。也就是說,當同一支手機使用兩顆以上的同一機種鏡頭時,滿足前述條件之成像透鏡組可避免因鏡頭的品質差異所造成的影響。 In the present invention, the outer diameter of the first lens is D1, the outer diameter of the second lens is D2, and the minimum diameter of the fourth conical surface is ψ4, which satisfies the following condition: D1 Ψ4<D2. Thereby, the aforementioned imaging lens group can be applied to an optical design system of a larger aperture. Further, the outer diameter of the first lens is D1, and the minimum diameter of the fourth conical surface is ψ4, which satisfies the following condition: 0.9 < ψ 4 / D1 < 1.35. Thereby, a plurality of lenses can be made to face the center of the adjacent lenses by the cone, thereby reducing the influence of the conventional assembly tolerance. More specifically, the outer diameter of the first lens and the minimum diameter of the fourth conical surface may satisfy the following condition: 0.94 < ψ 4 / D1 < 1.15. Thereby, the quality difference between the lenses of the same model can be reduced. That is to say, when two or more lenses of the same type are used in the same mobile phone, the imaging lens group that satisfies the foregoing conditions can avoid the influence caused by the difference in quality of the lens.
此外,在本發明中第二透鏡之外徑為D2,第四圓錐面之寬度為w4,其可滿足下列條件:0.1<(π^2)×w4/D2<0.45。藉此,利用第四圓錐面的特定設計(如適當寬度),可維持以射出成型製造塑膠透鏡的可行性,避免塑膠透鏡的局部厚度過高,進而影響製造品質。再者,第四圓錐面之寬度、第四圓錐面之最小直徑以及第二圓錐面之最大直徑可滿足下列條件:2.2<(ψ4-ψ2)/(2×w4)<6.2。藉此,可形成局部較窄的次注料流道,作為彌補前述射出成型製程中射出速度過慢的生產對策,從而節省生產成本。更具體地,第四圓錐面之寬度、第四圓錐面之最小直徑以及第二圓錐面之最大直徑可滿足下列條件:2.8<(ψ4-ψ2)/(2×w4)<5.4。藉此,本發明之成像透鏡組的設計適用於短時間內需要大量生產的嚴苛生產條件。 Further, in the present invention, the outer diameter of the second lens is D2, and the width of the fourth conical surface is w4, which satisfies the following condition: 0.1 < (π^2) × w4 / D2 < 0.45. Thereby, by using the specific design of the fourth conical surface (such as the appropriate width), the feasibility of manufacturing the plastic lens by injection molding can be maintained, and the local thickness of the plastic lens can be prevented from being too high, thereby affecting the manufacturing quality. Further, the width of the fourth conical surface, the minimum diameter of the fourth conical surface, and the maximum diameter of the second conical surface may satisfy the following conditions: 2.2 < (ψ4-ψ2) / (2 × w4) < 6.2. Thereby, a locally narrow secondary injection flow path can be formed as a production countermeasure to compensate for the excessively slow injection speed in the injection molding process, thereby saving production costs. More specifically, the width of the fourth conical surface, the minimum diameter of the fourth conical surface, and the maximum diameter of the second conical surface may satisfy the following condition: 2.8 < (ψ4-ψ2) / (2 × w4) < 5.4. Thereby, the design of the imaging lens unit of the present invention is suitable for severe production conditions requiring mass production in a short period of time.
在本發明中,第二透鏡與第三透鏡之間可僅以 第四圓錐面與第三圓錐面接觸,以減少第二鏡片承受不必要的承靠擠壓力,而可適用於外徑差距較大的成像透鏡組。此外,在本發明中,部分之第三圓錐面於垂直並遠離中心軸之一方向上可不與第二透鏡交疊。此種保留空氣間隙的設計,可避免單一透鏡本身圓錐面的真圓度影響透鏡間組合的密合度。 In the present invention, the second lens and the third lens may be in contact with the third conical surface only to reduce the second lens to bear unnecessary bearing pressing force, and may be applied to the outer diameter difference. Larger imaging lens set. Further, in the present invention, a portion of the third conical surface may not overlap the second lens in a direction perpendicular to and away from one of the central axes. This design of the air gap is preserved to avoid the roundness of the conical surface of the single lens itself affecting the tightness of the combination between the lenses.
藉由上述提及的各技術特徵,本發明進一步提供包含有前述實施方式之成像透鏡組的成像鏡頭模組,而前述成像透鏡組可利用其接合結構與成像鏡頭模組中之至少一透鏡或一不透光零件(Opaque member)接合。當成像透鏡組與透鏡接合時,其中心軸可與透鏡的光軸對正,增加光學精度,維持良好的成像品質。又或者,當成像透鏡組係與不透光零件接合時,其可增加成像鏡頭模組整體結構的穩定度,不易因外在環境的碰撞而影響成像鏡頭模組的成像品質。 The present invention further provides an imaging lens module including the imaging lens group of the foregoing embodiment, wherein the imaging lens group can utilize at least one lens of the imaging lens module or An Opaque member is joined. When the imaging lens assembly is engaged with the lens, its central axis can be aligned with the optical axis of the lens, increasing optical precision and maintaining good image quality. Or, when the imaging lens assembly is bonded to the opaque component, the stability of the overall structure of the imaging lens module can be increased, and the imaging quality of the imaging lens module is not easily affected by the collision of the external environment.
具體地,前述不透光零件可為成像鏡頭模組的一塑膠鏡筒,但本發明不以此為限。此時,成像透鏡組可沿中心軸設置於塑膠鏡筒內。更具體地,塑膠鏡筒包含一鏡筒開孔,且前述鏡筒開孔的最小內徑位置可為成像鏡頭模組的光圈。藉此,有利於降低成像鏡頭模組的機構複雜度。 Specifically, the opaque component may be a plastic lens barrel of the imaging lens module, but the invention is not limited thereto. At this time, the imaging lens group can be disposed in the plastic lens barrel along the central axis.

It should be noted that, as can be seen from the partial enlarged view in FIG. 1A, a portion of the third conical surface 134 does not overlap the second lens 120 in a direction perpendicular and away from the central axis z, that is, in the second axial connection. In the structure, the edge of the second lens 120 and the edge of the third lens 130 retain an air gap in the direction of the vertical central axis z, so that the roundness of the conical surface of the single lens itself can be prevented from affecting the tightness of the combination between the lenses.

By designing the angle of the conical surface to avoid the roundness of the conical surface of the single lens itself, the adhesion of the combination between the lenses is affected, thereby increasing the feasibility of mass production. Similarly, the angle between the fourth conical surface 126 and the central axis z is α2, and it is disposed corresponding to the angle between the third conical surface 134 and the central axis z (ie, α4) to be mutually assembled.

In general, the optical element may be, but is not limited to, a lens, an imaging compensating element, a light shielding sheet, a spacer ring or a fixing ring.
