Description
本發明涉及一種鏡頭模組，同時還涉及一種鏡頭模組的組裝方法。 The invention relates to a lens module, and to a method for assembling a lens module.
隨著多媒體技術的發展，具有照相功能的電子產品越來越為廣大消費者所青睞，在人們對電子產品追求小型化的同時，對其拍攝出物體的影像品質提出了更高要求，即希望拍攝物體的影像畫面清晰。 With the development of multimedia technology, electronic products with camera functions are increasingly favored by consumers. While people are pursuing miniaturization of electronic products, they have put forward higher requirements for the image quality of the objects they shoot. The image of the subject is clear.
目前大多數電子產品的相機模組包括一鏡筒及裝於鏡筒內的一第一鏡片、一間隔環和一第二鏡片。鏡筒的一端向內延伸形成一環形的擋止部。第一鏡片、間隔環、第二鏡片依次收容在鏡筒中，其中第一鏡片與擋止部相抵持，該間隔環用於隔離第一鏡片與第二鏡片，使第一鏡片與第二鏡片之間間隔一定距離以滿足該鏡頭模組光學設計的需求。所述第二鏡片的外徑小於該鏡筒的內徑。該鏡頭模組於組裝時，通常係將第一鏡片、間隔環依序放在該鏡筒中，並使得第一鏡片與鏡筒的擋止部相抵持，之後用一具有針狀注膠部的注膠器在間隔環遠離第一鏡片的表面外圓周塗以UV膠(Ultraviolet glue，紫外膠)，再壓入第二鏡片，然後通過紫外光照射將該UV膠加以固化，使第二鏡片固定在鏡筒內，從而將鏡筒內的元件固定於鏡筒的擋止部與第二鏡片之間。 At present, the camera module of most electronic products includes a lens barrel and a first lens, a spacer ring and a second lens mounted in the lens barrel. One end of the lens barrel extends inwardly to form an annular stop. The first lens, the spacer ring and the second lens are sequentially received in the lens barrel, wherein the first lens abuts against the blocking portion, the spacer ring is used for isolating the first lens and the second lens, so that the first lens and the second lens A certain distance between them to meet the needs of the optical design of the lens module. The outer diameter of the second lens is smaller than the inner diameter of the lens barrel. When the lens module is assembled, the first lens and the spacer ring are sequentially placed in the lens barrel, and the first lens is abutted against the stopping portion of the lens barrel, and then a needle-shaped injection portion is used. The glue applicator is coated with UV glue (Ultraviolet glue) on the outer circumference of the spacer ring away from the surface of the first lens, and then pressed into the second lens, and then the UV glue is cured by ultraviolet light irradiation to fix the second lens. In the lens barrel, the components in the lens barrel are fixed between the stopper portion of the lens barrel and the second lens.
為使第二鏡片較穩固的固定在鏡筒內，通常會在間隔環的表面上多處點膠，該點膠量不易控制，一方面，在壓入該第二鏡片後通過紫外光照射將該UV膠加以固化時，易有溢膠的現象發生，由於液體虹吸的作用會使得第二鏡片朝向遠離擋止部的一端浮動，從而導致組裝後的第一鏡片、第二鏡片和鏡筒之間的同心度很難確定，影響整個鏡頭的成像品質；另一方面，容易造成各處點膠量不均勻而導致第二鏡片與鏡筒及間隔環的黏接處產生應力，在長期使用之下，第二鏡片易由鏡筒及間隔環上脫落而導致該相機鏡頭模組無法使用。 In order to fix the second lens in the lens barrel more stably, the glue is usually dispensed on the surface of the spacer ring. The amount of glue is not easy to control. On the one hand, after being pressed into the second lens, ultraviolet light will be irradiated. When the UV glue is cured, the phenomenon of overflowing the glue is easy to occur, and the action of the liquid siphon causes the second lens to float toward the end away from the stopper, thereby causing the assembled first lens, the second lens and the lens barrel. The concentricity between the two is difficult to determine, affecting the imaging quality of the entire lens; on the other hand, it is easy to cause uneven dispensing in each place, resulting in stress on the bonding between the second lens and the lens barrel and the spacer ring. Next, the second lens is easily detached from the lens barrel and the spacer ring, and the camera lens module cannot be used.
有鑒於此，有必要提供一種可提高透鏡與鏡筒之間定位精度的鏡頭模組及其組裝方法。 In view of the above, it is necessary to provide a lens module and a method of assembling the same that can improve the positioning accuracy between the lens and the lens barrel.

該間隔環30呈圓環狀，其厚度根據該鏡頭模組100的光學需求設定。該間隔環30中部設置有一貫通的通孔31。該通孔31的直徑略大於所述第一、第二透鏡20、40的光學部22的直徑。 The spacer ring 30 has an annular shape, and the thickness thereof is set according to the optical requirement of the lens module 100. A through hole 31 is formed in the middle of the spacer ring 30. The diameter of the through hole 31 is slightly larger than the diameter of the optical portion 22 of the first and second lenses 20, 40.
組裝時，先將第一透鏡20和間隔環30依次從鏡筒10的開口端13置入鏡筒10內，其中，該第一透鏡20的固持部24的物端面241與擋止壁12的內表面相抵靠，該第一透鏡20的固持部24的外側面243與筒體11的第一階梯面112相對。由於第一透鏡20的外徑小於該鏡筒10內第一階梯面112處的內徑，該第一透鏡20的固持部24的 外側面243與鏡筒10的第一階梯面112之間形成間隙。接著，再將第二透鏡40從鏡筒10的開口端13壓入鏡筒10內，第一透鏡20的突塊21分別伸入第二透鏡40的凹槽41內，第二透鏡40向鏡筒10的擋止壁12擠壓第一透鏡20，使得第一透鏡20的固持部24的物端面241與擋止壁12的內表面之間緊密貼合，該第二透鏡40的固持部24的外側面243於靠近擋止壁12的頂端部分2430與鏡筒10的第一階梯面112相互緊貼，外側面243於靠近開口端13的底端部分2432恰好正對該第一階梯面112和第二階梯面114之間的倒角116的位置處，從而於該第二透鏡40的外側面243的底端部分2432與鏡筒10的筒體11的內表面之間間隔形成一環形的點膠空間50，且該第二透鏡40的像端面242上的凹陷43與該點膠空間50連通。由於第二透鏡40的外徑略大於該鏡筒10的第一階梯面112處的內徑，因此，第二透鏡40通過其固持部24的外側面243與鏡筒10的第一階梯面112之間相互卡緊而預定位。然後於點膠空間50內點入UV黏膠(Ultraviolet glue，紫外膠)，再通過紫外光加以照射固化，從而將第二透鏡40固定在該鏡筒10內，同時，該鏡筒10內第一透鏡20、間隔環30也相應緊固於擋止壁12與第二透鏡40之間。 In the assembly, the first lens 20 and the spacer ring 30 are firstly inserted into the lens barrel 10 from the open end 13 of the lens barrel 10 , wherein the object end surface 241 of the holding portion 24 of the first lens 20 and the blocking wall 12 are The inner surface abuts, and the outer side surface 243 of the holding portion 24 of the first lens 20 opposes the first step surface 112 of the cylinder 11. Since the outer diameter of the first lens 20 is smaller than the inner diameter of the first step surface 112 in the lens barrel 10, the holding portion 24 of the first lens 20 A gap is formed between the outer side surface 243 and the first step surface 112 of the lens barrel 10. Then, the second lens 40 is pressed into the lens barrel 10 from the open end 13 of the lens barrel 10, and the protrusions 21 of the first lens 20 respectively extend into the grooves 41 of the second lens 40, and the second lens 40 is mirrored. The stopper wall 12 of the barrel 10 presses the first lens 20 such that the object end surface 241 of the holding portion 24 of the first lens 20 and the inner surface of the stopper wall 12 are in close contact with each other, and the holding portion 24 of the second lens 40 The outer side surface 243 is in close contact with the first step surface 112 of the lens barrel 10 near the top end portion 2430 of the stopper wall 12, and the outer side surface 243 is just facing the first step surface 112 near the bottom end portion 2432 of the open end 13. And a position of the chamfer 116 between the second step surface 114, so that a gap is formed between the bottom end portion 2432 of the outer side surface 243 of the second lens 40 and the inner surface of the barrel 11 of the lens barrel 10 The dispensing space 50 is disposed, and the recess 43 on the image end surface 242 of the second lens 40 is in communication with the dispensing space 50. Since the outer diameter of the second lens 40 is slightly larger than the inner diameter of the first step surface 112 of the lens barrel 10, the second lens 40 passes through the outer side surface 243 of the holding portion 24 and the first step surface 112 of the lens barrel 10. They are stuck to each other and pre-positioned. Then, UV glue (UV glue) is inserted into the dispensing space 50, and then cured by ultraviolet light to fix the second lens 40 in the lens barrel 10, and at the same time, the lens barrel 10 is A lens 20 and a spacer ring 30 are also fastened between the blocking wall 12 and the second lens 40, respectively.
在上述組裝過程中，由於第二透鏡40的固持部24的外側面243的頂端部分2430與鏡筒10之間相互卡緊，因此在後續壓入第二透鏡40後點膠並通過紫外光加以照射固化的步驟中，第二透鏡40不會由於液體虹吸作用而浮動，且第一透鏡20與第二透鏡40之間通過突塊21與凹槽41的相互卡合，從而可以確保組裝後第一透鏡20和第二透鏡40之間有較好的同心度；第二透鏡40與鏡筒10之間的固定只需要在第二透鏡40的外側面243的底端部分2432與鏡筒10的第一階梯面112和第二階梯面114之間的倒角116處點膠即可，因 此該點膠量容易控制，且第二透鏡40上的凹陷43可以提供膠體在固化期間由於受熱而輕微膨脹的空間，不僅可以避免污染透鏡而影響其光學性能，而且組裝後第二透鏡40與鏡筒10之間可以形成均勻和穩固的連接，提高組裝良率。 In the above assembly process, since the top end portion 2430 of the outer side surface 243 of the holding portion 24 of the second lens 40 and the lens barrel 10 are mutually engaged, after being pressed into the second lens 40, the glue is applied and ultraviolet light is applied thereto. In the step of irradiating and curing, the second lens 40 does not float due to liquid siphoning, and the first lens 20 and the second lens 40 are engaged with each other by the protrusion 21 and the groove 41, thereby ensuring the post-assembly. There is good concentricity between a lens 20 and the second lens 40; the fixation between the second lens 40 and the lens barrel 10 only needs to be at the bottom end portion 2432 of the outer side surface 243 of the second lens 40 and the lens barrel 10 The chamfer 116 between the first step surface 112 and the second step surface 114 can be dispensed, because The amount of dispensing is easy to control, and the recess 43 on the second lens 40 can provide a space for the colloid to slightly expand due to heat during curing, which not only avoids contamination of the lens but affects its optical performance, but also assembles the second lens 40 with A uniform and stable connection can be formed between the lens barrels 10 to improve assembly yield.
上述鏡頭模組100中，點膠空間50形成於第二透鏡40的外側面243與鏡筒10內表面所設倒角之間，該點膠空間50還可以為其他形成方式。 In the lens module 100, the dispensing space 50 is formed between the outer side surface 243 of the second lens 40 and the chamfered surface of the inner surface of the lens barrel 10. The dispensing space 50 can also be formed in other manners.
如圖3所示，本發明第二實施方式提供的一鏡頭模組100a。該鏡頭模組100a與第一實施方式中的鏡頭模組100的區別僅在於點膠空間50a的位置。本實施方式中，第二透鏡40a的外側面243的底端部分2432設有一倒角2433，而在鏡筒11a的內表面上則未設置倒角，點膠空間50a形成於鏡筒11a的內表面與第二透鏡40a上所設倒角2433之間。 As shown in FIG. 3, a lens module 100a according to a second embodiment of the present invention. The lens module 100a differs from the lens module 100 of the first embodiment only in the position of the dispensing space 50a.
