200825491 還可包括光圈片、濾光片以及間隔環等元件，為了簡單、 清楚地描述光學鏡頭模組100之結構，本實施例僅以鏡筒 •中裝設複數個透鏡120為例進行說明光學鏡頭模組100之 -結構。所述鏡筒140包括一鏡筒主體110與一封口裝置130。 如圖2所示，鏡筒主體110具有一第一底面111，一第 二底面112以及連接第一底面111及第二底面112之側壁 113。第二底面112與一底座（圖未標示）相結合。鏡筒主體 110之侧壁113具有一内表面114，與内表面114相對之一 / 4 外表面115以及兩個安裝侧面116a，且所述每個安裝側面 116a上分別開設有豎槽116b。所述侧壁113之内表面114 與外表面115同時與鏡筒主體110之第一底面111、第二底 面112垂直，所述每個安裝側面116a同時與内表面114、 外表面115、第一底面111、第二底面112相鄰。所述側壁 113上開設有一貫通内表面114與外表面115之開口 116， 該開口 116由側壁113之兩安裝側面116a定義出，該開口 I 116作為將透鏡120送入鏡筒主體110空腔中之通道。從内 表面114與一安裝侧面116a相交之一端向内表面114與另 一安裝侧面116a相交之另一端圍繞鏡筒主體110之軸線於 側壁113内開設有至少一個第一凹槽117，所述第一凹槽 117為一弧形凹槽，且該弧形第一凹槽117之曲率與鏡筒主 體110之内表面114之曲率相同。第一凹槽117用於裝設 透鏡120。 透鏡120具有一第一邊緣部121，一第二邊緣部122 以及位於第一邊緣部121與第二邊緣部122之間之主體部 11 200825491 123。第一邊緣部121與第二邊緣部122為相對於透鏡120 之主體部123呈對稱結構，即，第一邊緣部121與第二邊 •緣部122結構、尺寸均相同。所述第一邊緣部121與第二 •邊緣部122用於與鏡筒主體110之第一凹槽117配合，將 透鏡120水平安裝於鏡筒主體110中，且使得透鏡120之 主體部123恰好處於鏡筒主體110之空腔中，這樣進入鏡 筒主體110之光線可穿過透鏡120之主體部123。 所述第一凹槽117具有一底面118及兩相對之側面 119，且第一凹槽117之結構由所述底面118及兩相對之側 面119所定義出。第一凹槽117之深度（即第一凹槽117之 底面118到鏡筒主體110内表面114之距離）與高度（即第一 凹槽117之兩相對側面119之間之距離）與透鏡120之第一 邊緣部121及第二邊緣部122之相應尺寸相同，以實現第 一凹槽117與第一邊緣部121及第二邊緣部122之配合。 為方便描述透鏡120之第一邊緣部121及第二邊緣部122 ， 之結構以及與第一凹槽117之具體配合情況，第一邊緣端 部121定義有一第一外端面124,第二邊緣部122定義有一 第二外端面125。具體地，第一凹槽117之深度等於第一邊 緣部121之第一外端面124到主體部123與第一邊緣部121 之臨界面之距離，同樣，第一凹槽117之深度亦等於第二 邊緣部122之第二外端面125到主體部123與第二邊緣部 122之臨界面之距離。第一凹槽117之高度等於第一邊緣部 121及第二邊緣部122之厚度。這樣，當透鏡120裝設於鏡 筒主體110中時，透鏡120之第一邊緣部121與第二邊緣 12 200825491 部122恰好容置於鏡筒主體110之第一凹槽117中，同時 透鏡120之主體部123會定位於鏡筒主體110之空腔内。 胃 所述第一凹槽117之數量等於要裝設之透鏡120之數 .量，相鄰第一凹槽117之間之距離同樣根據要裝設之相鄰 透鏡120之間之距離確定。本實施例中，要裝設之透鏡120 為三個，相應地，鏡筒主體110中開設三個第一凹槽117。 鏡筒主體110之開口 116之尺寸亦要根據要裝設之透 鏡120之尺寸及數量確定。由於鏡筒主體11〇中至少要裝 設一個透鏡120，因此，開口 116沿鏡筒主體I10軸向之開 口高度要大於或等於一個透鏡120之厚度’當透鏡U0之 厚度不一致時，開口 116沿鏡筒主體11〇軸向之開口高度 要大於或等於透鏡120之最大厚度；同時，開口 116沿鏡 筒主體110軸向之開口高度要小於或等於鏡筒主體110之 高度。所述開口 116沿與鏡筒主體110轴線垂直之橫向開 口尺寸（即，鏡筒主體110側壁113之兩安裝側面U6a之間 之距離）要大於或等於透鏡120最大直徑，當透鏡120為不 規則形狀其厚度不一致時，開口 116沿與鏡筒主體110軸 線垂直之橫向開口尺寸要大於或等於透鏡120之最大直 徑，這樣可以確保透鏡120水平地穿過開口 116而安裝到 鏡筒主體110中。 所述封口裝置130用於與鏡筒主體11〇之開口 116相 配合，從而使得透鏡120容置於連續地或者封閉地鏡筒主 體110中。所述封口裝置130為一弧面形板體結構，其結 構、尺寸恰好與鏡筒主體110之開口 116相對應，即，將 13 200825491 該封口裝置130安裝到開口 116處與鏡筒主體110配合後 可形成一連續之筒體結構。 • 所述封口裝置130具有一内表面131、一與内表面131 *相對之外表面132、一頂面133、一與頂面133相對之底面 134、兩側面135。當該封口裝置130與鏡筒主體110配合 後形成一連續之筒體結構時，封口裝置130之頂面133會 與鏡筒主體110之第一底面111相結合形成一連續地、封 閉地環面，封口裝置130之底面134與鏡筒主體110之第 二底面112相結合形成另一連續地、封閉地環面，封口裝 置130之内表面131與鏡筒主體110之内表面114相結合 形成一連續之圓筒面。 所述封口裝置130之兩側面135上分別形成有兩凸緣 136，其分別與定義鏡筒主體110之開口 116之兩安裝侧面 116a上之兩豎槽116b相對應，用於將封口裝置130與鏡筒 主體110相結合並固定。本實施例中，該兩凸緣136為相 同之長方體結構，兩豎槽116b為恰好容置上述兩凸緣136 之長方體凹槽。當透鏡120於鏡筒主體110内安裝完成後， 封口裝置130之兩凸緣136分別從鏡筒主體110之兩豎槽 116b所在第一底面111端插入到豎槽116b中，將封口裝置 130嵌入到開口 116中，這樣便使得透鏡120可封閉地裝設 於被封閉之鏡筒主體110中。 為使得封口裝置130與鏡筒主體110結合後能夠更好 地容置、調整以及固定透鏡120，優選地，封口裝置130 包括與第一凹槽117向配合之第二凹槽137,所述第二凹槽 14 200825491 137與第一凹槽117可形成一連續之環槽。本實施例中，從 封口裝置130之内表面131向封口裝置130内部開設與鏡 •筒主體110内第一凹槽117相配合、貫通之第二凹槽137。 •第二凹槽137之結構、尺寸與第一凹槽117相同，這樣， 當封口裝置130插入開口 116與鏡筒主體110配合後，封 口裝置130會與鏡筒主體110形成一連續地圓筒體結構， 同時，第二凹槽137亦將會與第一凹槽117相貫通且於所 述連續之圓筒體結構内壁形成一連續之環槽。 ， 封口裝置130之兩凸緣136與鏡筒主體110之兩豎槽 116b之間之接觸面可通過膠水黏結固定、超聲波焊接固定 等方式。此外，封口裝置130之外表面132與鏡筒主體110 之側壁113之外表面115可形成有螺紋結構，用於將所述 之光學頭鏡模組100整體與其它之結構配合。 本技術方案第二實施例提供於組裝上述光學透鏡模組 100過程中夾持透鏡120之夾具40。如圖3所示，所述夾 ^ 具40包括一主體410，至少一夾持部420以及連接所述夾 持部420與主體410之至少一懸臂430。所述懸臂430 —端 與主體410相連，另一端設置有夾持部420。所述懸臂430 可與主體410 —體成型，亦可移動地設置於410上。所述 夾持部420用於夾持透鏡120之第二邊緣部122。 本實施例中，懸臂430可移動地連結於主體410上。 具體地，主體410上開設一溝槽411，用收容懸臂430之一 端並實現懸臂430於溝槽411中移動，從而可調整懸臂430 之位置，當調整懸臂430之位置移動到預定位置後，可利 15 200825491 用一鎖固元件440將懸臂43〇之一端固定於溝槽内。 為實現一次夾持複數個透鏡12〇進行安裝，夹持部420 -和懸臂430可設置為複數個，且夾持部420與懸臂430之 數量相等。由於通常情況下，複數個透鏡12〇於鏡筒主體 110内會相互平行排布，因此，複數個懸臂43〇相應地設置 為互相平行，這樣可實現複數個夾持部42〇所夾持之複數 個透鏡120處於相互平行之平面内，以利於安裝。 例如，待安裝的透鏡12〇為三個，那麼相應地，夹持 部420與懸臂430可分別設置三個。此外，由於三個透鏡 120於鏡筒主體11〇中間隔一定距離且平行排布，例如三個 透鏡12〇間距相同’為完成此三個透鏡12G之—次安裝， 可將三個懸臂430之間之間距調整為與上述三個透鏡12〇 之間之間距相等’且三個懸臂430相互平行，這樣，安裝 透鏡120時’每—透鏡120可分別同時對準鏡筒主體110 内各自待配合之第—凹槽117 ’以利於安裝。此外，所述三 個懸臂430之長度應相同，且三個懸臂430分別支撐同樣 之夾持/1^420，並且每一夾持部42〇同等程度地夾持透鏡 、2〇之第一邊緣部122，這樣可以確保三個透鏡120之第一 邊緣^ 121均處於同—豎直平面内，當移動夾具40之主體 P 410將—個透鏡12G送人鏡筒主體11G進行安裝時，三 ，透鏡120之第—邊緣部121之外端面124可同時抵靠鏡 筒之no第一凹槽117之底面118，這樣利於三個透鏡mo 整體上同時且穩定地安裝。 421，一與第一夾片 所述夾持部420具有一第一夾片 16 200825491 421相對且平行放置之第二夾片422以及將第一夾片421 與第二夹片422之相同端連結起來之連接部423，因此，夾 •持部420整體上呈U字形。所述第一夾片421與第二夾片 -422之間之距離可根據待夾持之物件之尺寸進行調整，例如 第一夾片421與第二夾片422可於連結部423上進行移動， 通常使用時，先將第一夾片421與第二夾片422之間距離 調整足夠大以將待夾持物件如透鏡120之第二邊緣部122 放到第一夾片421與第二夾片422之間，然後調整第一夾 r 片421與第二夾片422相對移動，直至第二邊緣部122被 夾緊。 為實現所述夾持部420與透鏡120之第二邊緣部122 更好地配合，第一夾片421與第二夾片422用於與第二邊 緣部122之表面相接觸之表面之形狀及尺寸相同，以使第 一夾片421、第二夾片422與第二邊緣部122緊密結合，從 而利於夾具40穩固地將透鏡120裝入鏡筒主體110中。 ; 本技術方案第三實施例提供一種利用第二實施例中之 夾具40對第一實施例之光學透鏡模組100進行組裝之方 法。第一實施例之光學透鏡模組100包括三個透鏡120，相 應地，第二實施例之夾具40設置有三個懸臂430與三個夾 持部420。組裝光學透鏡模組100之過程包括以下步驟。首 先，將三個鏡片120之第二邊緣部122分別夾固於夾具40 之三個夾持部420。三個夾持部420同等程度地夾持三個透 鏡120之第二邊緣部122,使得三個透鏡120之第一邊緣部 121均處於同一豎直平面内。 17 200825491 其次，移動夾具40之主體410到鏡筒主體110之開口 116處，將三個透鏡120之第一邊緣部121分別對準各自對 •應之第一凹槽117,繼續移動主體410直至三個透鏡120之 .第一邊緣部121全部插入到鏡筒主體110之第一凹槽117 中，同時透鏡120基本全部處於鏡筒主體110之空腔中。 此時，透鏡120之主體部123基本上處於鏡筒主體110之 中心區域，例如，當主體部123為規則之圓柱形體時，主 體部123處於鏡筒主體110中心區域係指主體部123之軸 線與鏡筒主體110之轴線共線。並且，第二邊緣部122之 外端面125基本上處於開口 116處且位於第一凹槽117底 面118所處環面之延長面上。 於此安裝步驟中，可沿鏡筒主體110之軸線於鏡筒主 體110之軸線延長線區域設置一光學檢測裝置，對評估鏡 頭品質之參數如中偏心、MTF值等進行測量。 MTF(Modulation Transfer Function，調製傳遞函數）值係綜 I 合反映光學鏡頭模組品質好壞之參數。當通過檢測發現初 步安裝好（未進行固定）之光學鏡頭模組100之品質達不到 預定要求，可以直接對光學鏡頭模組100中之各元件進行 調整、修正或更換，以使整個光學鏡頭模組100之品質達 到要求。當調整、修正或更換各元件後整個光學鏡頭模組 100還不能達到要求時，需要進行重新組裝，此時由於只完 成初步裝配，光學鏡頭模組100中之部分元件還可通過拆 卸進行再利用。 當經上述光學檢測後光學鏡頭模組100滿足要求時， 18 200825491 可將鏡筒主體110中之各光學元件如透鏡120進行固定。 各光學元件與鏡筒主體110之間之固定方式通常採用光固 •化膠進行膠合，所述光固化膠通常為紫外固化膠。在本實 •施例中，可於透鏡120安裝入鏡筒主體110内部之前先於 第一凹槽117中塗覆紫外固化膠水（紫外光照射後才會固 化），然後依照上述方法裝入透鏡120，再配合調整三個透 鏡120之位置對裝有三個透鏡120光學鏡頭模組100進行 光學檢測，當光學鏡頭模組100之光學參數滿足要求時， * ' 最後利用紫外光照射第一凹槽117中之紫外固化膠水直至 紫外固化膠水固化，從而將三個透鏡120與鏡筒主體110 固定。 經上述檢測、固定後，光學鏡頭模組100基本完成了 預組裝，為了防止鏡筒主體110中之光學元件如透鏡120 被污染，或者為了使得此預組裝之光學鏡頭模組100方便 與其他光學元件進行配合，或者為了確保配合時不會損傷 纟鏡筒主體110中之光學元件如透鏡120,需要進一步對鏡筒 主體110之開口 116進行封合。 因此，光學透鏡模組100之組裝過程還包括最後一步， 即，將封口裝置130與鏡筒主體110之開口 116進行配合。 具體來說，將封口裝置130的兩凸緣136分別從鏡筒主體 110之兩豎槽116b所在第一底面111端插入到豎槽116b 中，直至封口裝置130之底面134與鏡筒主體110之第二 底面112處於同一平面並形成封閉之環面，同時封口裝置 130之頂面133與鏡筒主體110之第一底面111亦處於同一 19 200825491 平面並形成封閉之環面，此時，封口裝置130嵌入到開口 116中並與鏡筒主體110結合形成封閉之筒體。這樣，便完 -成了光學鏡頭模組100之組裝過程。 • 本技術方案之光學鏡頭模組100具有以下特點：首先， 由於其鏡筒主體110所具有之結構特點，即，具有側向開 口 116,可以使得鏡筒主體110轴向開口上方區域可放置光 學檢測儀器，從而實現於安裝透鏡120等光學元件之同時 可對各光學元件之裝配情況進行即時量測，得以實現即時 、 評估光學鏡頭模組100之品質；其次，光學鏡頭模組100 還具有一封口裝置130,於鏡筒主體110内之光學元件組裝 完成後與鏡筒主體110相配合，一方面可確保鏡筒主體110 内光學元件不被污染，另一方面鏡筒主體110與其他元件 配合時其内之光學元件亦不會被損傷。 另外，本技術方案之光學鏡頭模組100之組裝方法具 有以下特點··首先，提供可方便安裝透鏡120之夾具40， ^ 其結構設計與待安裝之透鏡120相適應，可實現對透鏡120 之良好夾固；其次，由於該夾具40可同時夾持複數個透鏡 120,可實現鏡筒主體110中所需之複數個透鏡120之一次 安裝；最後，於安裝透鏡120之過程中，利用光學檢測裝 置對初步安裝（未進行固定）之光學鏡頭模組100進行光學 檢測，可即時地評估初步安裝之光學鏡頭模組100之性能 是否滿足要求，以實現對透鏡120或其他光學元件之調整 或修正，避免如先前技術所述之待整個光學鏡頭模組100 之組裝結束後進行檢測後發現問題時無法補救之隱患。 20 200825491 綜上所述，本發明確已符合發明專利之要件，遂依法 提出專利申請。惟，以上所述者僅為本發明之較佳實施方

[Embodiment] Hereinafter, the lens barrel of the technical solution, the optical module having the lens barrel, and the optical module assembled by the same will be described with reference to the accompanying drawings and the embodiments. The method is described in detail. As shown in FIG. 1, the first embodiment of the present technical solution provides an optical module such as an optical lens module 100. The optical lens module 100 includes a lens barrel 140 and at least one lens 120. Of course, the optical lens module 100 generally includes components such as an aperture plate, a filter, and a spacer ring. In order to simply and clearly describe the structure of the optical lens module 100, the present embodiment only uses a plurality of lens barrels and a central device. The lens 120 is taken as an example to explain the structure of the optical lens module 100. The lens barrel 140 includes a barrel body 110 and a mouthpiece device 130. As shown in FIG. 2, the lens barrel main body 110 has a first bottom surface 111, a second bottom surface 112, and side walls 113 connecting the first bottom surface 111 and the second bottom surface 112. The second bottom surface 112 is combined with a base (not shown). The side wall 113 of the barrel main body 110 has an inner surface 114 opposite to the inner surface 114 of the outer surface 115 and the two mounting side surfaces 116a, and each of the mounting side surfaces 116a is provided with a vertical groove 116b. The inner surface 114 and the outer surface 115 of the side wall 113 are simultaneously perpendicular to the first bottom surface 111 and the second bottom surface 112 of the lens barrel main body 110, and each of the mounting side surfaces 116a simultaneously and the inner surface 114, the outer surface 115, and the first The bottom surface 111 and the second bottom surface 112 are adjacent to each other. The side wall 113 defines an opening 116 extending through the inner surface 114 and the outer surface 115. The opening 116 is defined by two mounting sides 116a of the side wall 113. The opening I 116 serves to feed the lens 120 into the cavity of the lens barrel main body 110. The channel. At least one first groove 117 is defined in the side wall 113 from the axis of the lens barrel main body 110 from the other end of the inner surface 114 intersecting the one side of the mounting surface 116a and the other side of the mounting surface 116a. A groove 117 is an arcuate groove, and the curvature of the curved first groove 117 is the same as the curvature of the inner surface 114 of the barrel body 110. The first recess 117 is for mounting the lens 120. The lens 120 has a first edge portion 121, a second edge portion 122, and a body portion 11 200825491 123 between the first edge portion 121 and the second edge portion 122. The first edge portion 121 and the second edge portion 122 are symmetric with respect to the main body portion 123 of the lens 120, that is, the first edge portion 121 and the second edge portion 122 are identical in structure and size. The first edge portion 121 and the second edge portion 122 are configured to cooperate with the first groove 117 of the lens barrel main body 110 to horizontally mount the lens 120 in the lens barrel main body 110, and the main body portion 123 of the lens 120 is just right. The light entering the barrel body 110 can pass through the body portion 123 of the lens 120. The first recess 117 has a bottom surface 118 and two opposite side surfaces 119, and the structure of the first recess 117 is defined by the bottom surface 118 and the opposite side surfaces 119. The depth of the first groove 117 (ie, the distance from the bottom surface 118 of the first groove 117 to the inner surface 114 of the barrel body 110) and the height (ie, the distance between the opposite sides 119 of the first groove 117) and the lens 120 The first edge portion 121 and the second edge portion 122 are of the same size to achieve the cooperation of the first groove 117 with the first edge portion 121 and the second edge portion 122. To facilitate the description of the structure of the first edge portion 121 and the second edge portion 122 of the lens 120 and the specific fit with the first groove 117, the first edge end portion 121 defines a first outer end surface 124 and a second edge portion. 122 defines a second outer end surface 125. Specifically, the depth of the first groove 117 is equal to the distance from the first outer end surface 124 of the first edge portion 121 to the critical surface of the main body portion 123 and the first edge portion 121. Similarly, the depth of the first groove 117 is equal to the first The distance between the second outer end surface 125 of the two edge portions 122 to the critical surface of the main body portion 123 and the second edge portion 122. The height of the first groove 117 is equal to the thickness of the first edge portion 121 and the second edge portion 122. Thus, when the lens 120 is mounted in the lens barrel main body 110, the first edge portion 121 and the second edge 12 200825491 portion 122 of the lens 120 are just received in the first groove 117 of the lens barrel main body 110 while the lens 120 is The body portion 123 is positioned within the cavity of the barrel body 110. The number of the first grooves 117 of the stomach is equal to the number of lenses 120 to be mounted. The distance between adjacent first grooves 117 is also determined according to the distance between adjacent lenses 120 to be mounted. In this embodiment, there are three lenses 120 to be mounted, and correspondingly, three first grooves 117 are defined in the lens barrel main body 110. The size of the opening 116 of the barrel body 110 is also determined by the size and number of the lens 120 to be mounted. Since at least one lens 120 is to be mounted in the lens barrel main body 11, the opening height of the opening 116 along the axial direction of the lens barrel main body I10 is greater than or equal to the thickness of one lens 120. When the thickness of the lens U0 is inconsistent, the opening 116 is along The height of the opening of the barrel main body 11 in the axial direction is greater than or equal to the maximum thickness of the lens 120; meanwhile, the opening height of the opening 116 along the axial direction of the barrel main body 110 is smaller than or equal to the height of the barrel main body 110. The opening 116 has a lateral opening dimension perpendicular to the axis of the barrel body 110 (ie, the distance between the two mounting sides U6a of the side wall 113 of the barrel body 110) greater than or equal to the maximum diameter of the lens 120, when the lens 120 is not When the regular shapes are inconsistent in thickness, the opening 116 has a lateral opening dimension perpendicular to the axis of the lens barrel main body 110 that is greater than or equal to the maximum diameter of the lens 120, which ensures that the lens 120 is horizontally inserted through the opening 116 into the barrel main body 110. . The sealing device 130 is adapted to cooperate with the opening 116 of the barrel main body 11 such that the lens 120 is housed in the continuous or closed barrel main body 110. The sealing device 130 is a curved surface plate structure, and its structure and size correspond to the opening 116 of the lens barrel main body 110, that is, the sealing device 130 is mounted to the opening 116 to cooperate with the lens barrel main body 110. A continuous barrel structure can then be formed. The sealing device 130 has an inner surface 131, an outer surface 132 opposite the inner surface 131, a top surface 133, a bottom surface 134 opposite the top surface 133, and two side surfaces 135. When the sealing device 130 cooperates with the lens barrel main body 110 to form a continuous cylindrical structure, the top surface 133 of the sealing device 130 is combined with the first bottom surface 111 of the lens barrel main body 110 to form a continuous, closed torus. The bottom surface 134 of the sealing device 130 is combined with the second bottom surface 112 of the lens barrel main body 110 to form another continuous, closed annular surface. The inner surface 131 of the sealing device 130 is combined with the inner surface 114 of the lens barrel main body 110 to form a Continuous cylindrical surface. The two side faces 135 of the sealing device 130 are respectively formed with two flanges 136 respectively corresponding to the two vertical grooves 116b on the two mounting sides 116a defining the opening 116 of the lens barrel main body 110 for the sealing device 130 and The barrel main body 110 is coupled and fixed. In this embodiment, the two flanges 136 have the same rectangular parallelepiped structure, and the two vertical grooves 116b are rectangular parallelepiped grooves that just receive the two flanges 136. After the lens 120 is mounted in the lens barrel main body 110, the two flanges 136 of the sealing device 130 are inserted into the vertical groove 116b from the first bottom surface 111 end of the two vertical grooves 116b of the lens barrel main body 110, respectively, and the sealing device 130 is embedded. In the opening 116, the lens 120 is closably mounted in the enclosed barrel body 110. In order to better accommodate, adjust and fix the lens 120 after the sealing device 130 is combined with the lens barrel main body 110, preferably, the sealing device 130 includes a second groove 137 that cooperates with the first groove 117, the first The two grooves 14 200825491 137 and the first groove 117 can form a continuous ring groove. In this embodiment, a second recess 137 is formed from the inner surface 131 of the sealing device 130 to the inside of the sealing device 130 in cooperation with the first recess 117 in the mirror body 110. The structure and size of the second recess 137 are the same as those of the first recess 117. Thus, when the sealing device 130 is inserted into the opening 116 and the lens barrel main body 110, the sealing device 130 forms a continuous cylinder with the barrel main body 110. The body structure, at the same time, the second groove 137 will also penetrate the first groove 117 and form a continuous ring groove on the inner wall of the continuous cylindrical structure. The contact surface between the two flanges 136 of the sealing device 130 and the two vertical grooves 116b of the lens barrel main body 110 can be fixed by glue bonding, ultrasonic welding or the like. In addition, the outer surface 132 of the sealing device 130 and the outer surface 115 of the side wall 113 of the lens barrel body 110 may be formed with a threaded structure for integrally fitting the optical head mirror module 100 with other structures. The second embodiment of the present technical solution provides a jig 40 for holding the lens 120 during assembly of the optical lens module 100 described above. As shown in FIG. 3, the clip 40 includes a main body 410, at least one clamping portion 420, and at least one cantilever 430 connecting the clamping portion 420 and the main body 410. The cantilever 430 is connected at its end to the body 410 and at the other end with a clamping portion 420. The cantilever 430 can be integrally formed with the body 410 or movably disposed on the 410. The clamping portion 420 is for holding the second edge portion 122 of the lens 120. In this embodiment, the cantilever 430 is movably coupled to the main body 410. Specifically, a groove 411 is defined in the main body 410, and one end of the cantilever 430 is received to move the cantilever 430 in the groove 411, so that the position of the cantilever 430 can be adjusted. When the position of the cantilever 430 is adjusted to a predetermined position, 。 15 200825491 A locking element 440 is used to secure one end of the cantilever 43 于 in the groove. In order to mount the plurality of lenses 12A at a time, the holding portion 420- and the cantilever 430 may be provided in plural, and the number of the holding portions 420 and the cantilever 430 is equal. Since a plurality of lenses 12 are arranged in parallel with each other in the main body 110 of the lens barrel 110, a plurality of cantilevers 43 are correspondingly arranged in parallel with each other, so that a plurality of clamping portions 42 can be held. The plurality of lenses 120 are in planes parallel to each other to facilitate mounting. For example, the number of lenses 12 to be mounted is three, and accordingly, the holding portion 420 and the cantilever 430 may be respectively provided in three. In addition, since the three lenses 120 are arranged at a certain distance and in parallel in the barrel main body 11〇, for example, the distance between the three lenses 12〇 is the same. 'To complete the installation of the three lenses 12G, three cantilevers 430 can be used. The distance between the two lenses is adjusted to be equal to the distance between the three lenses 12' and the three cantilevers 430 are parallel to each other. Thus, when the lens 120 is mounted, each lens 120 can be simultaneously aligned with the respective body of the lens barrel 110 to be matched. The first - groove 117 'to facilitate installation. In addition, the lengths of the three cantilevers 430 should be the same, and the three cantilevers 430 respectively support the same clamping/1^420, and each clamping portion 42〇 clamps the lens, the first edge of the second edge to the same extent. The portion 122 can ensure that the first edges 121 of the three lenses 120 are all in the same-vertical plane. When the main body P 410 of the moving jig 40 sends the lens 12G to the lens barrel main body 11G for installation, The outer end surface 124 of the first edge portion 121 of the lens 120 can simultaneously abut the bottom surface 118 of the first groove 117 of the lens barrel, which facilitates simultaneous and stable mounting of the three lenses mo as a whole. 421. The first clamping piece 420 has a second clamping piece 422 opposite to the first clamping piece 16 200825491 421 and the first clamping piece 421 and the second clamping piece 422 are connected to the same end. Since the connecting portion 423 is raised, the clip holding portion 420 has a U shape as a whole. The distance between the first clip 421 and the second clip 422 can be adjusted according to the size of the object to be clamped. For example, the first clip 421 and the second clip 422 can be moved on the joint 423. Generally, the distance between the first clip 421 and the second clip 422 is adjusted to be large enough to place the object to be clamped, such as the second edge portion 122 of the lens 120, to the first clip 421 and the second clip. Between the sheets 422, the first clip r 421 and the second clip 422 are then moved relative to each other until the second edge portion 122 is clamped. In order to achieve a better fit between the clamping portion 420 and the second edge portion 122 of the lens 120, the shape of the surface of the first clip 421 and the second clip 422 for contacting the surface of the second edge portion 122 and The dimensions are the same so that the first clip 421 and the second clip 422 are tightly coupled with the second edge portion 122, thereby facilitating the clamp 40 to firmly fit the lens 120 into the lens barrel main body 110. The third embodiment of the present technical solution provides a method of assembling the optical lens module 100 of the first embodiment by using the jig 40 of the second embodiment. The optical lens module 100 of the first embodiment includes three lenses 120, and correspondingly, the jig 40 of the second embodiment is provided with three cantilevers 430 and three holding portions 420. The process of assembling the optical lens module 100 includes the following steps. First, the second edge portions 122 of the three lenses 120 are respectively clamped to the three clamping portions 420 of the jig 40. The three clamping portions 420 hold the second edge portions 122 of the three lenses 120 to the same extent such that the first edge portions 121 of the three lenses 120 are all in the same vertical plane. 17 200825491 Next, moving the main body 410 of the jig 40 to the opening 116 of the lens barrel main body 110, respectively aligning the first edge portions 121 of the three lenses 120 with the first grooves 117 of the respective pairs, and continuing to move the main body 410 until The first edge portion 121 of the three lenses 120 is all inserted into the first groove 117 of the barrel main body 110 while the lens 120 is substantially entirely in the cavity of the barrel main body 110. At this time, the main body portion 123 of the lens 120 is substantially in the central region of the lens barrel main body 110. For example, when the main body portion 123 is a regular cylindrical body, the main body portion 123 is in the central region of the lens barrel main body 110 and refers to the axis of the main body portion 123. It is collinear with the axis of the barrel body 110. Also, the outer end surface 125 of the second edge portion 122 is substantially at the opening 116 and is located on the extended surface of the annulus where the bottom surface 118 of the first recess 117 is located. In this mounting step, an optical detecting device may be disposed along the axis of the lens barrel main body 110 in the axis extension line of the lens barrel main body 110, and parameters for evaluating the quality of the lens such as the center eccentricity, the MTF value, and the like are measured. The MTF (Modulation Transfer Function) value ensemble I reflects the parameters of the quality of the optical lens module. When it is found through inspection that the quality of the initially mounted (unfixed) optical lens module 100 does not meet the predetermined requirements, the components in the optical lens module 100 can be directly adjusted, corrected or replaced to make the entire optical lens The quality of the module 100 meets the requirements. When the entire optical lens module 100 cannot meet the requirements after adjusting, correcting, or replacing each component, reassembly is required. At this time, some components of the optical lens module 100 can be reused by disassembly because only preliminary assembly is completed. . When the optical lens module 100 satisfies the requirements after the above optical detection, 18 200825491 can fix each optical component in the lens barrel main body 110 such as the lens 120. The manner in which the optical elements are fixed to the barrel body 110 is typically glued with a light-curing adhesive, typically a UV-curable adhesive. In the embodiment, the ultraviolet curing glue (curing only after ultraviolet light irradiation) may be applied to the first groove 117 before the lens 120 is mounted inside the lens barrel main body 110, and then loaded into the lens 120 according to the above method. And optically detecting the optical lens module 100 equipped with three lenses 120 in conjunction with adjusting the position of the three lenses 120. When the optical parameters of the optical lens module 100 meet the requirements, * 'the last groove 117 is irradiated with ultraviolet light. The UV-curable glue is cured until the UV-curable glue solidifies, thereby fixing the three lenses 120 to the barrel main body 110. After the above detection and fixing, the optical lens module 100 is substantially pre-assembled, in order to prevent the optical component such as the lens 120 in the lens barrel main body 110 from being contaminated, or to make the pre-assembled optical lens module 100 convenient and other optical. Further, the opening 116 of the barrel body 110 needs to be sealed in order to ensure that the components do not interfere with the optical elements such as the lens 120 in the barrel body 110 during assembly. Therefore, the assembly process of the optical lens module 100 further includes a final step of mating the sealing device 130 with the opening 116 of the barrel body 110. Specifically, the two flanges 136 of the sealing device 130 are respectively inserted into the vertical groove 116b from the end of the first bottom surface 111 of the two vertical grooves 116b of the lens barrel main body 110 until the bottom surface 134 of the sealing device 130 and the lens barrel main body 110. The second bottom surface 112 is in the same plane and forms a closed annular surface, and the top surface 133 of the sealing device 130 and the first bottom surface 111 of the lens barrel main body 110 are also in the same 19 200825491 plane and form a closed torus. At this time, the sealing device 130 is embedded in the opening 116 and combined with the barrel body 110 to form a closed barrel. Thus, it is completed - the assembly process of the optical lens module 100. The optical lens module 100 of the present invention has the following features: First, due to the structural features of the lens barrel body 110, that is, having the lateral opening 116, the lens barrel body 110 can be placed in the upper axial region to be optically placed. The optical instrument module 100 further has an optical sensor module 100 having an instant measurement of the optical components of the lens 120 while the optical components such as the lens 120 are mounted. The sealing device 130 cooperates with the lens barrel main body 110 after the optical components in the lens barrel main body 110 are assembled, and ensures that the optical components in the lens barrel main body 110 are not contaminated on the one hand, and the lens barrel main body 110 cooperates with other components on the other hand. The optical components within it will not be damaged. In addition, the assembling method of the optical lens module 100 of the present technical solution has the following features: First, the jig 40 for conveniently mounting the lens 120 is provided, and the structural design thereof is adapted to the lens 120 to be mounted, and the lens 120 can be realized. Good clamping; secondly, since the clamp 40 can simultaneously hold the plurality of lenses 120, one installation of the plurality of lenses 120 required in the lens barrel main body 110 can be realized; finally, in the process of mounting the lens 120, optical detection is performed. The device optically detects the optical lens module 100 that is initially installed (not fixed), and can immediately evaluate whether the performance of the initially mounted optical lens module 100 meets the requirements to achieve adjustment or correction of the lens 120 or other optical components. In the prior art, the hidden troubles that cannot be remedied when the problem is discovered after the assembly of the entire optical lens module 100 is completed are avoided. 20 200825491 In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case.
