Description
本發明涉及偏心檢測裝置，特別涉及一種用於檢測鏡片偏心度之偏心檢測裝置。 The present invention relates to an eccentricity detecting device, and more particularly to an eccentricity detecting device for detecting lens eccentricity.
隨著多媒體技術之飛速發展，數位相機(請參見Capturing images with digital still cameras,Micro,IEEE Volume：18,issue：6,Nov.-Dec.1998 Page(s)：14-19)、攝像機及帶有攝像頭之手機越來越受廣大消費者青睞，人們對數位相機、攝像機及手機攝像頭拍攝物體之影像品質提出更高要求之同時，對數位相機、攝像機及帶有攝像頭之手機等產品需求量也日益增加。數位相機、攝像機及手機攝像頭等攝影裝置中，鏡頭係一不可缺少之部件。 With the rapid development of multimedia technology, digital cameras (see Capturing images with digital still cameras, Micro, IEEE Volume: 18, issue: 6, Nov.-Dec. 1998 Page(s): 14-19), cameras and belts Mobile phones with cameras are increasingly favored by consumers. People are demanding higher image quality for digital cameras, camcorders and mobile phone cameras. At the same time, the demand for digital cameras, camcorders and mobile phones with cameras is also high. Increasing. Among the camera devices such as digital cameras, camcorders, and mobile phone cameras, the lens is an indispensable component.
鏡片作為鏡頭中之重要部件，對鏡頭整體之成像品質起到關鍵性作用。鏡片經成型、研磨及拋光後，其光軸往往會偏離其幾何中心軸，此現象稱為偏心。理論上鏡片之偏心可分為兩種，一種為光軸與幾何中心平行平移，另一種為光軸與鏡片幾何中心交叉，而實際上鏡片之偏心通常為這兩種偏心之組合。 As an important part of the lens, the lens plays a key role in the overall image quality of the lens. After the lens is shaped, ground and polished, its optical axis tends to deviate from its geometric central axis. This phenomenon is called eccentricity. Theoretically, the eccentricity of the lens can be divided into two types, one is that the optical axis is parallel to the geometric center, and the other is that the optical axis intersects the geometric center of the lens. In fact, the eccentricity of the lens is usually a combination of the two eccentricities.
傳統之鏡片偏心量測方法有複數種，其中一種鏡片偏心量測方法首先採用准直儀測量出鏡片之第一曲率中心。其次，繞准直儀之 中心軸線轉動鏡片一定角度後再採用准直儀測量出鏡片之第二曲率中心，以測量出鏡片相對於准直儀處於不同位置時之鏡片之曲率中心。根據兩次測量出之鏡片曲率中心經幾何換算後即可得到鏡片偏心量。然而，採用手動轉動鏡片之方式轉動鏡片，不僅轉動角度難以確定；而且可能由於施力不均，使鏡片之轉動軸偏離准直儀之中心軸線，即，兩次測量之曲率中心並非均相對於准直儀之中心軸線，從而導致測量結果可能出現偏差。 There are a plurality of conventional lens eccentricity measuring methods. One of the lens eccentricity measuring methods first uses a collimator to measure the first curvature center of the lens. Second, around the collimator After the central axis rotates the lens at a certain angle, the second curvature center of the lens is measured by the collimator to measure the center of curvature of the lens when the lens is at different positions relative to the collimator. The lens eccentricity is obtained by geometrically converting the center of curvature of the lens measured twice. However, rotating the lens by manually rotating the lens not only makes the rotation angle difficult to determine; but also may cause the rotation axis of the lens to deviate from the central axis of the collimator due to uneven application of force, that is, the center of curvature of the two measurements is not always relative to The center axis of the collimator, which may cause deviations in the measurement results.
有鑑於此，提供一種可避免兩次測量鏡片之曲率中心之過程中鏡片轉動角度偏差以及轉動中心偏移之偏心檢測裝置實屬必要。 In view of the above, it is necessary to provide an eccentricity detecting device which can avoid the deviation of the rotation angle of the lens and the deviation of the rotation center during the process of measuring the center of curvature of the lens twice.
以下將以實施例說明一種偏心檢測裝置。 An eccentricity detecting device will be described below by way of example.

The eccentricity detector is used for eccentricity detection of the object to be detected. The carrying device is configured to carry an object to be detected. The eccentric detector is detachably mated with the carrier. The eccentric detector has at least two first snap-fit structures that are equiangularly distributed with respect to a central axis of the eccentric detector. The carrier has at least two second snap structures. The at least two second engaging structures respectively cooperate with the at least two first engaging structures to cooperate after the carrying device rotates at a certain angle with respect to the eccentric detector.
與先前技術相較，該偏心檢測裝置之偏心檢測器及承載裝置藉由至少兩個第一卡合結構與至少兩個第二卡合結構之配合，使承載裝置相對於偏心檢測器轉動一定角度後進行配合，從而使得偏心檢測裝置兩次檢測待檢測物體之曲率中心過程中，待測物體轉動 之角度精確且轉動之軸線固定，避免待檢測物體轉動角度之偏差以及轉動中心之偏移，提高測量結果準確率。 Compared with the prior art, the eccentricity detector and the carrying device of the eccentricity detecting device rotate the carrier device by a certain angle with respect to the eccentricity detector by the cooperation of the at least two first engaging structures and the at least two second engaging structures. After the cooperation, the eccentricity detecting device detects the curvature center of the object to be detected twice, and the object to be tested rotates The angle is accurate and the axis of rotation is fixed, which avoids the deviation of the rotation angle of the object to be detected and the deviation of the rotation center, thereby improving the accuracy of the measurement result.

The main body portion 11 is used for eccentricity detection of the object to be detected. In the embodiment, the main body portion 11 is a self-collimator, which includes a light source, a reticle, an objective lens and the like. The light source is used to emit a detection beam. The score board has a crosshair mark. The objective lens is used for focusing the light emitted by the light source through the reticle to the crosshair to be focused on the object to be detected, so that the object to be detected transmits, refracts or reflects the light having the crosshair, thereby performing transmission, refraction or The reflected light gives the center of curvature of the object to be inspected. The first mating portion 12 is for mating with the carrier device 20. The first mating portion 12 has a first through hole 13 corresponding to the light source of the main body portion 11 such that light emitted from the light source of the main body portion 11 can be emitted from the first through hole 13. In this embodiment, the first through hole 13 is a circular through hole. First match The joint 12 has a first contact surface 14 remote from the body portion 11. The first contact surface 14 is adapted to cooperate with the carrying device 20, and at least two first engaging structures 15 are disposed thereon, and the at least two first engaging structures 15 are equiangularly distributed with respect to a central axis of the eccentric detector 10. The angle between the adjacent two first engaging structures and the center of the first contact surface is equal, and both are α. In this embodiment, the first engaging structures 15 are two. The angle α between the two first engaging structures 15 and the center of the first contact surface 14 is 180°, that is, the line connecting the two first engaging structures 15 is perpendicular to the central axis of the first mating portion 12. intersect. The first engaging structure 15 can be a protrusion or a groove. The two first engaging structures 15 may be distributed on the first contact surface 14 away from the central axis of the main body portion 11 or at a position close to the central axis of the main body portion 11. In this embodiment, the first engaging structure 15 is a groove located on the first contact surface 14 away from the central axis of the main body portion 11.
承載裝置20包括遠離第一配合部12之承載部21、靠近第一配合部12之第二配合部22以及連接於承載部21與第二配合部之間之連接部23。 The carrying device 20 includes a carrying portion 21 away from the first mating portion 12, a second mating portion 22 adjacent to the first mating portion 12, and a connecting portion 23 connected between the carrying portion 21 and the second mating portion.
承載部21具有一遠離第二配合部22之承載面21a，承載面21a用於與待檢測物體接觸以承載待檢測物體。承載部21之外徑可與待檢測物體之外徑大約相同。本實施例中，承載部21之外徑小於第二配合部22之外徑，待檢測物體可為鏡片。 The carrying portion 21 has a bearing surface 21a remote from the second engaging portion 22 for contacting the object to be detected to carry the object to be detected. The outer diameter of the bearing portion 21 may be approximately the same as the outer diameter of the object to be inspected. In this embodiment, the outer diameter of the bearing portion 21 is smaller than the outer diameter of the second mating portion 22, and the object to be detected may be a lens.
第二配合部22用於與第一配合部12相配合，從而使得承載裝置20與偏心檢測器10相配合。如圖2及圖3所示，第二配合部22包括一配合套筒25以及一連接於配合套筒25之配合蓋體26，配合套筒25為空心圓筒，配合蓋體26連接於配合套筒25靠近承載部21之一端。配合套筒25以及配合蓋體26共同構成一容置腔27。配合蓋體26 具有用於與第一接觸面14相接觸之第二接觸面28，第二接觸面28上具有形狀及位置均與至少兩個第一卡合結構15相對應之至少兩個第二卡合結構29。且，相鄰兩個第一卡合結構與第一接觸面中心之連線之夾角亦均為α，以便該承載裝置20相對於偏心檢測器10轉動α之整數倍後才可進行配合。本實施例中，由於第一卡合結構15為兩個凹槽，故第二卡合結構29相應地為兩個凸起結構。本實施例中，該兩個第一卡合結構15與第一接觸面14中心連線之夾角α亦為180°，承載裝置20與偏心檢測器10完成一次位置配合之後，必須圍繞偏心檢測器10之中心軸線轉動180°之整數倍，第二卡合結構29才能再次與第一卡合結構15相配合，承載裝置20與偏心檢測器10才能具有再次之位置配合。 The second mating portion 22 is adapted to cooperate with the first mating portion 12 such that the carrier device 20 mates with the eccentric detector 10. As shown in FIG. 2 and FIG. 3, the second engaging portion 22 includes a mating sleeve 25 and a mating cover 26 connected to the mating sleeve 25. The mating sleeve 25 is a hollow cylinder, and the mating cover 26 is coupled to the mating body. The sleeve 25 is adjacent to one end of the carrier portion 21. The fitting sleeve 25 and the mating cover 26 together form a receiving cavity 27. Fit the cover 26 Having a second contact surface 28 for contacting the first contact surface 14 , the second contact surface 28 having at least two second engaging structures each having a shape and a position corresponding to the at least two first engaging structures 15 29. Moreover, the angle between the adjacent two first engaging structures and the line connecting the centers of the first contact faces is also α, so that the carrier device 20 can be engaged with respect to the eccentricity detector 10 by an integral multiple of α. In this embodiment, since the first engaging structure 15 is two grooves, the second engaging structure 29 is correspondingly two convex structures. In this embodiment, the angle α between the two first engaging structures 15 and the center line of the first contact surface 14 is also 180°, and the carrier device 20 and the eccentricity detector 10 must surround the eccentric detector after completing a positional cooperation. The central axis of 10 is rotated by an integral multiple of 180°, and the second engaging structure 29 can again cooperate with the first engaging structure 15, and the carrying device 20 and the eccentric detector 10 can have a positional cooperation again.
由於承載部21之外徑小於第二配合部22之外徑，本實施例中，連接部23靠近承載部21部分之外徑小於其靠近第二配合部22部分之外徑。 Since the outer diameter of the bearing portion 21 is smaller than the outer diameter of the second engaging portion 22, in the present embodiment, the outer diameter of the connecting portion 23 near the portion of the carrying portion 21 is smaller than the outer diameter of the portion of the connecting portion 21 near the second engaging portion 22.
承載裝置20具有貫通該承載部21、第二配合部22以及連接部23之第二通孔24。第二通孔24與第一通孔13相連通，以使得從主體部11發出之光線可依次穿過第一通孔13以及第二通孔24到達承載於承載部21之待檢測物體並對其進行檢測。優選地，第二通孔24與第一通孔13同軸，且第二通孔24之孔徑小於第一通孔13之孔徑。 The carrying device 20 has a second through hole 24 penetrating the carrying portion 21, the second engaging portion 22, and the connecting portion 23. The second through hole 24 communicates with the first through hole 13 so that the light emitted from the main body portion 11 can sequentially pass through the first through hole 13 and the second through hole 24 to reach the object to be detected carried on the carrying portion 21 and It is tested. Preferably, the second through hole 24 is coaxial with the first through hole 13 , and the second through hole 24 has a smaller aperture than the first through hole 13 .
以上述偏心檢測裝置100對待檢測物體進行偏心量測時，可採用如下步驟： When the eccentricity detecting device 100 performs the eccentricity measurement on the object to be detected, the following steps may be taken:
第一步，將待檢測物體例如鏡片放置於承載裝置20之承載部21。 In the first step, an object to be detected, such as a lens, is placed on the carrier 21 of the carrier 20.
第二步，檢測鏡片之第一曲率中心。具體地，先將承載裝置20對準第一配合部12並使第一配合部12容置或部分容置於容置腔27內，本實施例中第一配合部12部分容置於容置腔27內。再轉動調整承載裝置20，使得第二卡合結構29與第一卡合結構15相配合，從而使得承載裝置20與偏心檢測器10位於第一配合位置。第二卡合結構29與第一卡合結構15配合後，即可使得偏心檢測器10之主體部11發出檢測光線，從而檢測獲得鏡片之第一曲率中心。 In the second step, the first center of curvature of the lens is detected. Specifically, the first mating portion 12 is firstly received in the accommodating cavity 27, and the first mating portion 12 is partially accommodated in the accommodating cavity 27 in this embodiment. Inside the cavity 27. The adjustment carrier 20 is then rotated such that the second engagement structure 29 cooperates with the first engagement structure 15 such that the carrier 20 and the eccentric detector 10 are in the first mating position. After the second engaging structure 29 is engaged with the first engaging structure 15, the main body portion 11 of the eccentric detector 10 emits detection light, thereby detecting the first center of curvature of the lens.
第三步，檢測鏡片之第二曲率中心。具體地，先取下承載裝置20並將其轉動180°，再將承載裝置20對準第一配合部12並使第一配合部12再次容置於容置腔27內，從而第二卡合結構29可再次與第一卡合結構15相配合，從而使得承載裝置20與偏心檢測器10位於第二配合位置。此時，鏡片相對於檢測第一曲率中心之位置恰同軸轉動了180°，可從偏心檢測器10之主體部11獲得鏡片之第二曲率中心。偏心檢測器10根據兩次測量出之鏡片曲率中心進行幾何換算即可得到鏡片偏心量，優選地，偏心檢測器10可連接一用於顯示檢測結果之顯示器。 In the third step, the second center of curvature of the lens is detected. Specifically, the carrier device 20 is first removed and rotated by 180°, and then the carrier device 20 is aligned with the first mating portion 12 and the first mating portion 12 is again accommodated in the accommodating cavity 27, so that the second engaging structure 29 can again cooperate with the first engagement structure 15 such that the carrier 20 and the eccentric detector 10 are in the second mating position. At this time, the lens is rotated coaxially by 180° with respect to the position at which the first center of curvature is detected, and the second center of curvature of the lens can be obtained from the body portion 11 of the eccentric detector 10. The eccentricity detector 10 obtains the lens eccentricity based on geometrically converted the center of curvature of the two measured lenses. Preferably, the eccentricity detector 10 can be connected to a display for displaying the detection result.
可理解，當第一卡合結構15為三個，該三個第一卡合結構15相對於偏心檢測器10之中心軸線等角度分佈，相鄰兩個第一卡合結構15與第一接觸面14中心連線之夾角α為120°，承載裝置20與偏心檢測器10完成一次位置配合之後，必須圍繞偏心檢測器10之中心軸線轉動120°之整數倍，第二卡合結構29才能再次與第一卡合結構15相配合。依此類推，第一卡合結構15為N個，相鄰兩個第一卡合結構15與第一接觸面14中心之連線之夾角為α為360°/N，承 載裝置20與偏心檢測器10完成一次位置配合之後，必須圍繞偏心檢測器10之中心軸線轉動α(即360°/N)之整數倍，第二卡合結構29才能再次與第一卡合結構15相配合。 It can be understood that when the first engaging structures 15 are three, the three first engaging structures 15 are equiangularly distributed with respect to the central axis of the eccentric detector 10, and the adjacent two first engaging structures 15 are in contact with the first contact. The angle α of the center line of the face 14 is 120°, and after the carrier 20 and the eccentricity detector 10 complete a positional fit, they must be rotated by an integral multiple of 120° around the central axis of the eccentric detector 10, and the second engaging structure 29 can be again Cooperating with the first engaging structure 15. And so on, the first engaging structure 15 is N, and the angle between the adjacent two first engaging structures 15 and the center of the first contact surface 14 is α°360°/N. After the carrier device 20 and the eccentricity detector 10 complete a positional engagement, they must rotate an integral multiple of α (ie, 360°/N) around the central axis of the eccentric detector 10, and the second engaging structure 29 can be again engaged with the first engaging structure. 15 matches.
相較於先前技術，該偏心檢測裝置100之偏心檢測器10及承載裝置20藉由至少兩個第一卡合結構15與至少兩個第二卡合結構29之配合，使得承載裝置20相對於偏心檢測器10轉動一定角度後進行配合，從而使得偏心檢測裝置100兩次檢測待檢測物體之曲率中心過程中，待測物體轉動之角度精確且轉動之軸線固定，避免待檢測物體轉動角度偏差以及轉動中心偏移，提高測量結果準確率。 Compared with the prior art, the eccentricity detector 10 and the carrier device 20 of the eccentricity detecting device 100 cooperate with the at least two second engaging structures 29 by at least two first engaging structures 15 such that the carrying device 20 is opposite to the supporting device 20 After the eccentricity detector 10 rotates at a certain angle, the eccentricity detecting device 100 detects the center of curvature of the object to be detected twice, and the angle of rotation of the object to be tested is accurate and the axis of rotation is fixed, thereby avoiding the deviation of the rotation angle of the object to be detected and Rotate the center offset to improve the accuracy of the measurement results.
