Description
本發明有關於一種透鏡單元組裝裝置及其方法。更詳而言之，其有關於一種在附有照相機之行動電話等之照相機使用之透鏡單元中組入此鏡筒內之透鏡之組裝精確度穩定且縮短透鏡單元之組裝時間的透鏡單元組裝裝置及其方法。 The present invention relates to a lens unit assembly apparatus and method therefor. More specifically, it relates to a lens unit assembling apparatus which is stable in assembly precision of a lens incorporated in the lens barrel in a lens unit used for a camera equipped with a camera such as a camera with a camera, etc., and which shortens the assembly time of the lens unit. And its method.
由用於行動電話等之非球面透鏡等構成之透鏡單元被要求其組裝作業自動化，刪減人事費，並且縮短組裝時間，在預定時間生產預定製造個數(例如參照專利文獻1)。為了可以良好精確度裝配於鏡筒內徑***並組入鏡筒之透鏡，***並組入鏡筒之透鏡是透鏡外徑相對於鏡同內徑稍大，而形成微弱緊配合。 A lens unit which is constituted by an aspherical lens or the like for a mobile phone or the like is required to be automated in the assembly work, the staffing fee is reduced, and the assembly time is shortened, and the predetermined number of manufactures is produced at a predetermined time (for example, refer to Patent Document 1). In order to fit the lens inserted into the inner diameter of the lens barrel and assembled into the lens barrel with good precision, the lens inserted into the lens barrel is slightly larger than the outer diameter of the lens to form a weak tight fit.
因而，為以良好精確度將透鏡裝配於鏡筒之內徑，需對抗緊配合之阻力，將透鏡推入並壓入鏡筒之內徑。習知之透鏡單元組裝裝置以例如黑色合成樹脂製(例如PEEK(聚醚醚酮))之真空吸附噴嘴握持透鏡，將此透鏡*** 鏡筒，並且，以此真空吸附噴嘴將透鏡推入鏡筒，使透鏡密合鏡筒之透鏡裝設孔之底面，而將透鏡以正確姿勢組入鏡筒內。一般令真空吸附噴嘴為合成樹脂製之理由是為了不使透鏡受到損傷。 Therefore, in order to fit the lens to the inner diameter of the lens barrel with good precision, it is necessary to push the lens into and press the inner diameter of the lens barrel against the resistance of the tight fit. A conventional lens unit assembling device holds a lens by a vacuum adsorption nozzle made of, for example, a black synthetic resin (for example, PEEK), and inserts the lens. The lens barrel, and the vacuum suction nozzle pushes the lens into the lens barrel to close the lens to the bottom surface of the lens mounting hole of the lens barrel, and the lens is assembled into the lens barrel in the correct posture. Generally, the reason why the vacuum adsorption nozzle is made of synthetic resin is to prevent the lens from being damaged.
又，令真空吸附噴嘴為黑色之理由是為了補正透鏡之旋轉方向之組入相位，而使用透鏡之圖像檢測裝置，此圖像檢測裝置可正確地檢測透鏡之圖像。當使用合成樹脂製真空吸附噴嘴時，由於真空吸附噴嘴因將透鏡推入鏡筒之內徑時之反作用力受到擠壓而變形，故透鏡傾斜，而產生無法將透鏡以正確姿勢組入鏡筒之內徑之弊端。為防止真空吸附噴嘴受到擠壓而變形，使透鏡之組入速度減緩或使將透鏡推入鏡筒之內徑之力減弱來因應，但由於產生組裝時間增長之弊端，故不易設定最適當之組裝條件。 Further, the reason why the vacuum suction nozzle is black is to correct the phase of the rotation of the lens, and the image detecting device of the lens can accurately detect the image of the lens. When a vacuum adsorption nozzle made of a synthetic resin is used, since the vacuum adsorption nozzle is deformed by the reaction force when the lens is pushed into the inner diameter of the lens barrel, the lens is tilted, and the lens cannot be incorporated into the lens barrel in the correct posture. The drawback of the inner diameter. In order to prevent the vacuum adsorption nozzle from being deformed by being squeezed, the speed of the lens is slowed down or the force of pushing the lens into the inner diameter of the lens barrel is weakened, but the disadvantage of the assembly time is increased, so it is difficult to set the most appropriate one. Assembly conditions.
為防止真空吸附噴嘴受到擠壓而變形，考慮採用金屬製真空吸附噴嘴。然而，要採用金屬製真空吸附噴嘴，因上述理由，而需進行電鍍黑色處理，故於使用途有電鍍剝落，金屬製真空吸附噴嘴之耐久性產生問題。記載於專利文獻2之透鏡單元組裝裝置藉對鏡筒施加衝擊，而將透鏡順暢地推入鏡筒。又，記載於專利文獻3之透鏡單元組裝裝置藉將空氣吹至透鏡之上面，而於將真空吸附噴嘴移動至上方而離開透鏡時，防止帶著透鏡一起上升。 In order to prevent the vacuum adsorption nozzle from being deformed by being pressed, it is considered to use a metal vacuum adsorption nozzle. However, in order to use a metal vacuum adsorption nozzle, it is necessary to perform black plating treatment for the above reasons, so that plating peeling is used during use, and the durability of the metal vacuum adsorption nozzle is problematic. The lens unit assembly device described in Patent Document 2 applies a shock to the lens barrel to smoothly push the lens into the lens barrel. Moreover, the lens unit assembly device described in Patent Document 3 prevents the lens from rising together when the vacuum suction nozzle is moved upward to move away from the lens by blowing air onto the upper surface of the lens.

然而，習知所提出之該等透鏡組裝方法未必為正確地將鏡筒之內俓與透鏡之間的姿勢保持正確之方法，非進行正確之組裝之決定性方法。 However, the conventional lens assembly methods proposed by the prior art are not necessarily a method for correctly correcting the posture between the inner cylinder and the lens of the lens barrel, and are not a decisive method for correct assembly.

以下，依據圖式，說明本發明之實施形態。圖1是顯示本發明實施形態之透鏡單元組裝裝置1之整體平面圖。如圖1所示，本發明實施形態之透鏡單元組裝裝置1以第1組裝站(1ST)至第12組裝站(12ST)12個組裝站構成。12個各組裝站搭載安裝於焊接構造之基底11(參照圖4至圖6)上。第1組裝站(1ST)至第6組裝站(6ST)之6個組裝站從圖1所示之下方側之右端至左端等間隔形成。又，第7組裝站(7ST)至第12組 裝站(12ST)之6個組裝站如圖1所示，從上方側之左端至右端等間隔形成。第1組裝站(1ST)至第12組裝站(12ST)之12個組裝站的基本構造相同，細部略為不同。 Hereinafter, embodiments of the present invention will be described based on the drawings. Fig. 1 is a plan view showing the entirety of a lens unit assembling apparatus 1 according to an embodiment of the present invention. As shown in Fig. 1, a lens unit assembly apparatus 1 according to an embodiment of the present invention is constituted by twelve assembly stations of a first assembly station (1ST) to a twelfth assembly station (12ST). Each of the twelve assembly stations is mounted on a base 11 (see FIGS. 4 to 6) of a welded structure. The six assembly stations of the first assembly station (1ST) to the sixth assembly station (6ST) are formed at equal intervals from the right end to the left end of the lower side shown in Fig. 1 . Also, the 7th assembly station (7ST) to the 12th group As shown in Fig. 1, the six assembly stations of the station (12ST) are formed at equal intervals from the left end to the right end of the upper side. The 12 assembly stations of the first assembly station (1ST) to the twelfth assembly station (12ST) have the same basic structure, and the details are slightly different.
如圖1所示，在圖1之下方側與上方側(圖示上)兩側，直線狀下側引導軌道21與上側引導軌道22從圖1之右端架至左端方向(圖示上)方向而形成。此引導軌道主要由軌道及滑動器2個零件構成，為使用「滾動」來導引機械之直線運動部的一般機械要件零件。於下側引導軌道21與上側引導軌道22配置有受到此引導之塊體固定於下面之矩形板狀組裝托板23。此組裝托板23在上述下側引導軌道21與上側引導軌道22分別於等間隔位置配置有14個。14個組裝托板23在下側引導軌道21與上側引導軌道22受到引動，而同時移動1間距，將鏡筒依序從預定製程之組裝位置搬送至下個製程之組裝位置。 As shown in FIG. 1, on the lower side and the upper side (shown on the upper side) of FIG. 1, the linear lower side guide rail 21 and the upper side guide rail 22 are oriented from the right end frame to the left end direction (in the drawing direction) of FIG. And formed. The guide rail is mainly composed of two parts of a rail and a slider, and is a general mechanical component part that uses "rolling" to guide a linear moving portion of the machine. The lower guide rail 21 and the upper guide rail 22 are disposed with a rectangular plate-shaped assembly pallet 23 to which the guided block is fixed. In the assembly pallet 23, 14 of the lower guide rail 21 and the upper guide rail 22 are disposed at equal intervals. The 14 assembly pallets 23 are slid at the lower guide rails 21 and the upper guide rails 22, and simultaneously moved by 1 pitch, and the lens cylinders are sequentially transported from the assembly position of the predetermined process to the assembly position of the next process.
下方側之組裝托板23從下側引導軌道21之右端之組裝位置P1至左端之組裝位置P14各移動1間距，而分別定位於14處組裝位置(在本例中，左右兩端為用以搬送之待機站)。同樣地，上方側之組裝托板23從上側引導軌道22之左端之組裝位置P15至右端之組裝位置P28各移動1間距，而分別定位於14處組裝位置(在本例中，左右兩端為用以搬送之待機站)。此外，由於零件件數等因透鏡單元而異，故在本例之14處所有組裝位置不限於進行組裝作業，而在本實施形態中，此14處之組裝位置是指組裝托板23之停止位置。 The assembly pallet 23 on the lower side is moved by 1 pitch from the assembly position P1 of the right end of the lower guide rail 21 to the assembly position P14 of the left end, and is respectively positioned at 14 assembly positions (in this example, the left and right ends are used for Transfer standby station). Similarly, the assembly pallet 23 on the upper side is moved by 1 pitch from the assembly position P15 at the left end of the upper guide rail 22 to the assembly position P28 at the right end, and is respectively positioned at 14 assembly positions (in this example, the left and right ends are Used to transport the standby station). Further, since the number of parts and the like vary depending on the lens unit, all the assembly positions in the 14th example of the present example are not limited to the assembly work, but in the present embodiment, the assembly position at the 14 points refers to the stop of the assembly tray 23. position.
於下側引導軌道21與上側引導軌道22橫亙此軸 方向(圖1之左右方向)全長而形成有引導轉動體(軸承之滾珠、滾軸)之軌道面。於組裝托板23之下面安裝滑動器24(參照圖5、圖6)，此滑動器24受到下側引導軌道21與上側引導軌道22引導而移動。於滑動器24形成有供轉動體(滾珠或滾軸)循環之無限循環路徑。當滑動器24受到下側引導軌道21與上側引導軌道22引導而移動時，沿著下側引導軌道21與上側引導軌道22之轉動體軌道面，滑動器24內之轉動體轉動，滑動器24順暢地移動。對轉動體軌道面與轉動體之間賦與小預壓。因而，滑動器24對轉動體軌道面在無背隙下受到引導，而將組裝托板23在所有組裝站以高精確度定位於預定位置。因此，組裝零件時，不需將滑動器24鉗住固定於轉動體軌道面。 The lower guide rail 21 and the upper guide rail 22 traverse the axis A track surface that guides the rotating body (balls and rollers of the bearing) is formed in the entire direction (the horizontal direction in FIG. 1). A slider 24 (see FIGS. 5 and 6) is attached to the lower surface of the assembly pallet 23, and the slider 24 is guided by the lower guide rail 21 and the upper guide rail 22 to move. The slider 24 is formed with an infinite circulation path for circulating a rotating body (ball or roller). When the slider 24 is guided to be guided by the lower guide rail 21 and the upper guide rail 22, the rotator in the slider 24 is rotated along the rotator raceway surface of the lower guide rail 21 and the upper guide rail 22, and the slider 24 is rotated. Move smoothly. A small preload is applied between the rotor track surface and the rotor. Thus, the slider 24 is guided to the rotor body raceway without backlash, and the assembly pallet 23 is positioned at a predetermined position with high accuracy at all assembly stations. Therefore, when assembling the component, it is not necessary to clamp the slider 24 to the rotor track surface.
於透鏡單元組裝裝置1之左端形成有將組裝托板23從下側引導軌道21移送至上側引導軌道22之托板移送裝置3A。又，於透鏡單元組裝裝置1之右端形成有將組裝托板23從上側引導軌道22移送至下側引導軌道21之托板移送裝置3B。因而，在第1組裝站(1ST)至第6組裝站(6ST)之6個組裝站的組裝作業完畢之組裝托板23以托板移送裝置3A從下側引導軌道21移送至上側引導軌道22。 A pallet transfer device 3A that transfers the assembly pallet 23 from the lower guide rail 21 to the upper guide rail 22 is formed at the left end of the lens unit assembly device 1. Further, a pallet transfer device 3B that transfers the assembly pallet 23 from the upper guide rail 22 to the lower guide rail 21 is formed at the right end of the lens unit assembly device 1. Therefore, the assembly pallet 23 in which the assembly work of the six assembly stations of the first assembly station (1ST) to the sixth assembly station (6ST) is completed is transferred from the lower guide rail 21 to the upper guide rail 22 by the pallet transfer device 3A. .

The assembled pallet 23, which is assembled at the 12th assembly station (12ST) lens unit, removes the completed lens unit from the assembly pallet 23. The assembly tray 23 of the lens unit is removed The pallet transfer device 3B is transferred from the upper guide rail 22 to the lower guide rail 21 side, and the assembly work at the first assembly station (1ST) is resumed. That is, the assembly pallet 23 is cyclically moved in the clockwise direction (upper in FIG. 1) between the lower guide rail 21 and the upper guide rail 22 to be used repeatedly.

The Y-axis moving device 52 is disposed between the upper guide rail 22 and the lower guide rail 21. The reason why the Y-axis moving device 52 is disposed at this position is to open the vertical position (refer to FIG. 3), and to prevent such devices from interfering with each other as much as possible. The Y-axis moving device 52 is constituted by a Y-axis base 521 extending in the left-right direction of FIG. 2 and a Y-axis slider 522 guided by the Y-axis base 521 and moving in the left-right direction (Y-axis direction) of FIG. 2 .

The slider 512 is constructed. The X-axis slide 512 is driven in the X-axis direction by the X-axis servo motor 513, the X-axis ball screw 514, and the ball nut (not shown) (the left-right direction of FIG. 5). The Z-axis moving device 53 is mounted on the X-axis slider 512. The Z-axis moving device 53 is a Z-axis base 531 extending in the upper-lower direction (Z-axis direction) of FIG. 4, and a Z-axis slide 532 guided by the Z-axis base 531 and moving in the upper-lower direction (Z-axis direction) of FIG. Composition.
Z軸滑件532如圖5所示，以Z軸伺服馬達533、Z軸滾珠螺桿534及圖中未示之滾珠螺母於Z軸方向(上下方向)驅動。如圖4所示，θ軸旋轉裝置可旋轉地支承於Z軸滑件532，並具有於圖4之上下方向(Z軸方向)延伸之零件***軸541。零件***軸541以θ軸伺服馬達542，以所期之角度旋轉驅動。於零件***軸541之下端安裝有真空吸附構成透鏡單元之鏡筒B以從零件托盤41搬送至組裝托板23之鏡筒吸附頭543。鏡筒吸附頭543在本例中以黑色之合成樹脂(PEEK)成形，亦可為較軟之金屬製。 As shown in FIG. 5, the Z-axis slider 532 is driven in the Z-axis direction (up-and-down direction) by a Z-axis servo motor 533, a Z-axis ball screw 534, and a ball nut (not shown). As shown in FIG. 4, the θ-axis rotating device is rotatably supported by the Z-axis slider 532, and has a component insertion shaft 541 extending in the upper-lower direction (Z-axis direction) of FIG. The part insertion shaft 541 is rotationally driven at a desired angle by the θ-axis servo motor 542. A lens barrel B constituting the lens unit is vacuum-attached to the lower end of the part insertion shaft 541 to be carried from the part tray 41 to the barrel suction head 543 of the assembly tray 23. The lens barrel adsorption head 543 is formed of black synthetic resin (PEEK) in this example, or may be made of a softer metal.
將鏡筒B固定於托板23上之夾具之方法以以彈簧力一直按壓之2片固定板夾住來進行(圖中未示)。將鏡筒B***固定於夾具時，驅動氣缸，解除彈簧之按壓。當解除氣缸之驅動時，夾具固定鏡筒B。X軸基底511由於從Y軸滑件522之X軸方向之外伸量大，故採用用以抑制X軸基底511之撓曲或振動之支撐構造。即，於下側引導軌道21與上側引導軌道22之外側，各2個垂直支柱55、55、56、56之下端 固定於基底11上。支柱55、55、56、56之上端以水平之樑571、572、573、574相互連結。於平行於下側引導軌道21及上側引導軌道22之樑571、572之上面搭載並分別安裝有引導軌道581、581。 The method of fixing the lens barrel B to the jig on the pallet 23 is carried out by sandwiching two fixing plates which are pressed by a spring force (not shown). When the lens barrel B is inserted and fixed to the jig, the cylinder is driven to release the pressing of the spring. When the driving of the cylinder is released, the clamp fixes the barrel B. Since the X-axis base 511 has a large amount of extension from the X-axis direction of the Y-axis slide 522, a support structure for suppressing deflection or vibration of the X-axis base 511 is employed. That is, on the outer side of the lower side guide rail 21 and the upper side guide rail 22, the lower ends of each of the two vertical pillars 55, 55, 56, 56 It is fixed to the substrate 11. The upper ends of the pillars 55, 55, 56, 56 are connected to each other by horizontal beams 571, 572, 573, and 574. Guide rails 581 and 581 are mounted on the upper surfaces of the beams 571 and 572 parallel to the lower guide rail 21 and the upper guide rail 22, respectively.
滑動器582、582受到引導軌道581、581引導而於Y軸方向移動。於滑動器582、582安裝有垂直之支撐板583、583之上端。此支撐板583、583之下端連結於X軸基底511、511。支撐板583、583是將X軸基底511、511之外伸部以支柱55、55、56、56、樑571、572、573、574等支承而引導。因而，可抑制X軸基底511之撓曲或振動，而可進行零件***裝置5之高精確度之定位及高速動作。 The sliders 582 and 582 are guided by the guide rails 581 and 581 to move in the Y-axis direction. Upper ends of the vertical support plates 583, 583 are mounted to the sliders 582, 582. The lower ends of the support plates 583 and 583 are coupled to the X-axis bases 511 and 511. The support plates 583 and 583 guide the X-axis bases 511 and 511 beyond, and are supported by the pillars 55, 55, 56, 56, the beams 571, 572, 573, and 574. Therefore, the deflection or vibration of the X-axis base 511 can be suppressed, and the high-precision positioning and high-speed operation of the component insertion device 5 can be performed.
以鏡筒吸附頭543從零件托盤41取出之鏡筒B以CCD照相機等圖像檢測裝置61拍攝其下面，檢測圖像，以檢測鏡筒B之旋轉方向之相位。之後，以θ軸伺服馬達542旋轉驅動零件***軸541，將鏡筒B定位於預定旋轉角度方向之相位後，搬入至組裝托板23。於組裝托板23載置有圖中未示之夾緊夾具，以彈簧力將鏡筒B固定於夾緊夾具231。圖7(a)為顯示將鏡筒B固定於組裝托板23之夾緊夾具231之狀態的例。 The lens barrel B taken out from the component tray 41 by the lens barrel adsorption head 543 is imaged by an image detecting device 61 such as a CCD camera, and an image is detected to detect the phase of the rotation direction of the lens barrel B. Thereafter, the component insertion shaft 541 is rotationally driven by the θ-axis servo motor 542, and the lens barrel B is positioned at a phase in a predetermined rotation angle direction, and then carried into the assembly pallet 23. A clamping jig (not shown) is placed on the assembly pallet 23, and the lens barrel B is fixed to the clamp jig 231 by a spring force. FIG. 7(a) shows an example of a state in which the lens barrel B is fixed to the clamp jig 231 of the assembly pallet 23.
如圖5所示，托板搬送裝置7以托板卡合裝置71及托板間距進給裝置72構成。托板卡合裝置71可藉氣缸於圖5之上下方向移動，往上方向移動而卡合於組裝托板23。托板定位裝置62、62可藉氣缸於圖5之上下方向移動，往下方向移動而從組裝托板23、23脫離。托板卡合裝置71之上 端部具有旋轉自如地配置之圓筒軸承，此軸承可***組裝托板23之半圓筒(幾乎與軸承同徑)狀之缺口或者脫離而解除卡合。此托板卡合裝置71可同時進行用以搬送托板23、23之解除卡合與組裝時之定位兩者。 As shown in FIG. 5, the pallet transfer device 7 is constituted by a pallet engagement device 71 and a pallet pitch feeding device 72. The pallet engaging device 71 is movable by the cylinder in the upper and lower directions of FIG. 5, and moves upward to be engaged with the assembly pallet 23. The pallet positioning devices 62, 62 are movable by the cylinder in the up-down direction of FIG. 5, and are moved downward to be detached from the assembly pallets 23, 23. Above the pallet engaging device 71 The end portion has a cylindrical bearing that is rotatably disposed, and the bearing can be inserted into a notch or a detachment of the semi-cylindrical (almost the same diameter as the bearing) of the assembly pallet 23 to release the engagement. The pallet engagement device 71 can simultaneously perform both the engagement of the pallets 23, 23 and the positioning at the time of assembly.
托板間距進給裝置72以伺服馬達721、圖中未示之滾珠螺桿、圖中未示之滾珠螺母，於垂直於圖5之紙面之之方向的內側將托板卡合裝置71、71移動1間距。結果，將組裝位置P1之組裝托板23移動至組裝位置P2，將組裝位置P2之組裝托板23移動至組裝位置P3。同時，將組裝位置P3之組裝托板23移動至第2組裝站(2ST)之組裝位置P4。托板定位裝置62、62藉氣缸，往圖5之上方向移動，卡合於組裝托板23、23，，而將組裝托板23、23定位於組裝位置P2、P3。因而，在第1組裝站(1ST)之組裝位置P2，以零件***裝置5搬入有鏡筒B之組裝托板23移動至下個製程之組裝位置P3。在第1組裝站(1ST)之組裝位置P3，由於不需鏡筒B之推入作業，故不進行推入作業。 The pallet spacing feeding device 72 moves the pallet engaging devices 71, 71 on the inner side in the direction perpendicular to the paper surface of FIG. 5 by a servo motor 721, a ball screw (not shown), and a ball nut (not shown). 1 pitch. As a result, the assembly pallet 23 at the assembly position P1 is moved to the assembly position P2, and the assembly pallet 23 at the assembly position P2 is moved to the assembly position P3. At the same time, the assembly pallet 23 at the assembly position P3 is moved to the assembly position P4 of the second assembly station (2ST). The pallet positioning devices 62, 62 are moved by the cylinders in the upward direction of Fig. 5, and are engaged with the assembly pallets 23, 23, and the assembly pallets 23, 23 are positioned at the assembly positions P2, P3. Therefore, at the assembly position P2 of the first assembly station (1ST), the assembly pallet 23 in which the lens barrel B is carried by the component insertion device 5 is moved to the assembly position P3 of the next process. At the assembly position P3 of the first assembly station (1ST), since the pushing operation of the lens barrel B is not required, the pushing operation is not performed.
第2組裝站(2ST) 2nd assembly station (2ST)
接著，就第2組裝站(2ST)之構造與組裝動作作說明。圖3是顯示鄰接圖2之左側之第2組裝站(2ST)與第3組裝站(3ST)之放大平面圖。第2組裝站(2ST)是將透鏡L1(參照圖7(b))***組裝位置P4之組裝托板23之鏡筒B並且在下個組裝位置P5推入組裝托板23之透鏡L1(參照圖7(c))的組裝站。如圖3、圖4、圖5及圖6所示，第2組裝站(2ST)以零件托盤供給排出裝置4、零件***裝置5、圖像檢測裝置61、 托板定位裝置62、托板搬送裝置7、透鏡推入裝置8等構成。第2組裝站(2ST)與第1組裝站(1ST)之構造上之很大之不同點是於第2組裝站(2ST)附加有透鏡推入裝置8。因而，在以下之說明中，關於與第1組裝站(1ST)相同之部份，省略詳細之說明。 Next, the structure and assembly operation of the second assembly station (2ST) will be described. Fig. 3 is an enlarged plan view showing the second assembly station (2ST) and the third assembly station (3ST) adjacent to the left side of Fig. 2; The second assembly station (2ST) is a lens L1 that inserts the lens L1 (see FIG. 7(b)) into the lens barrel B of the assembly tray 23 at the assembly position P4 and pushes the assembly tray 23 at the next assembly position P5 (refer to the figure). Assembly station for 7(c)). As shown in FIGS. 3, 4, 5, and 6, the second assembly station (2ST) supplies the discharge device 4, the component insertion device 5, and the image detecting device 61 with the component tray. The pallet positioning device 62, the pallet transporting device 7, the lens pushing device 8, and the like are configured. The second assembly station (2ST) differs greatly from the first assembly station (1ST) in that a lens pushing device 8 is attached to the second assembly station (2ST). Therefore, in the following description, the detailed description of the same portions as the first assembly station (1ST) will be omitted.
多個透鏡L1等間隔地收納於零件托盤供給排出裝置4之零件托盤41。零件***裝置5如前述為X軸、Y軸、Z軸之3軸直角座標型機器人，並具有繞Z軸之旋轉軸θ軸。θ軸旋轉裝置之零件***軸541(參照圖4)以θ軸伺服馬達542旋轉驅動。於零件***軸541之下端安裝有真空吸附透鏡L1以從零件托盤41將透鏡L1搬送至組裝托板23之透鏡吸附頭544。為了以高精確度檢測透鏡L1之圖像，透鏡吸附頭544在本例中以黑色之合成樹脂(PEEK)成形。 The plurality of lenses L1 are housed in the component tray 41 of the component tray supply and discharge device 4 at equal intervals. The part insertion device 5 is a three-axis orthogonal coordinate type robot of the X-axis, the Y-axis, and the Z-axis as described above, and has a rotation axis θ axis about the Z-axis. The component insertion shaft 541 (see FIG. 4) of the θ-axis rotation device is rotationally driven by the θ-axis servo motor 542. A vacuum suction lens L1 is attached to the lower end of the part insertion shaft 541 to convey the lens L1 from the part tray 41 to the lens adsorption head 544 of the assembly tray 23. In order to detect the image of the lens L1 with high precision, the lens adsorption head 544 is formed in this example with a black synthetic resin (PEEK).
以透鏡吸附頭544從零件托盤41所取出之透鏡L1以CCD照相機等圖像檢測裝置61檢測透鏡L1之圖像，以檢測透鏡L1之旋轉方向之相位。之後，以θ軸伺服馬達542旋轉驅動零件***軸541，將透鏡L1定位於預定之旋轉角度之相位後，將透鏡L1搬入至組裝位置P4之組裝托板23，控制Z軸伺服馬達533之轉矩，以小按壓力將透鏡L1***鏡筒B內。此按壓力是控制Z軸伺服馬達533之旋轉轉矩來調整。圖7(b)顯示將透鏡L1以小按壓力***至鏡筒B之狀態。透鏡L1形成為輕微地放置於鏡筒B之透鏡L1裝設孔B1之入口的狀態。 The lens L1 taken out from the component tray 41 by the lens adsorption head 544 detects an image of the lens L1 by an image detecting device 61 such as a CCD camera to detect the phase of the rotation direction of the lens L1. Thereafter, the θ-axis servo motor 542 is rotationally driven to drive the component insertion shaft 541, and the lens L1 is positioned at a predetermined rotation angle, and the lens L1 is carried into the assembly pallet 23 of the assembly position P4 to control the rotation of the Z-axis servo motor 533. At the moment, the lens L1 is inserted into the barrel B with a small pressing force. This pressing force is adjusted by controlling the rotational torque of the Z-axis servo motor 533. Fig. 7(b) shows a state in which the lens L1 is inserted into the barrel B with a small pressing force. The lens L1 is formed in a state of being slightly placed at the entrance of the lens L1 of the lens barrel B to the hole B1.
由於將透鏡L1以小按壓力***至鏡筒B，故合成 樹脂製透鏡吸附頭544不致受到擠壓而變形，而可避免透鏡L1之中心線與鏡筒B之中心線不一致而透鏡L1之中心線傾斜之狀態等組裝精確度降低之弊端。使前述托板搬送裝置7作動，而使組裝位置P3之組裝托板23移動至組裝位置P4，同時，使組裝位置P4之組裝托板23移動至組裝位置P5。同時，將組裝位置P5之組裝托板23移動至第3組裝站(3ST)之組裝位置P6。 Since the lens L1 is inserted into the lens barrel B with a small pressing force, it is synthesized The resin lens suction head 544 is not deformed by being pressed, and the disadvantage that the assembly accuracy is lowered, such as a state in which the center line of the lens L1 does not coincide with the center line of the lens barrel B and the center line of the lens L1 is inclined, can be avoided. When the pallet conveyance device 7 is actuated, the assembly pallet 23 at the assembly position P3 is moved to the assembly position P4, and the assembly pallet 23 at the assembly position P4 is moved to the assembly position P5. At the same time, the assembly pallet 23 at the assembly position P5 is moved to the assembly position P6 of the third assembly station (3ST).
因而，在第2組裝站(2ST)之組裝位置P4，以零件***裝置5將透鏡L1***至鏡筒B之組裝托板23移動至第2組裝站(2ST)之組裝位置P5。於組裝位置P5配置有透鏡推入裝置8。如圖4、圖6所示，透鏡推入裝置8搭載於基底11之上面。透鏡推入裝置8以水平安裝之矩形平板狀基底板81、安裝於此基底板81之上面之垂直的柱體82、以可於垂直方向移動之方式軸支於此柱體82之垂直面的零件推入軸83、將零件推入軸83於垂直方向移動之氣缸84等構成。 Therefore, at the assembly position P4 of the second assembly station (2ST), the assembly pallet 23 in which the lens insertion L1 is inserted into the lens barrel B by the component insertion device 5 is moved to the assembly position P5 of the second assembly station (2ST). A lens pushing device 8 is disposed at the assembly position P5. As shown in FIGS. 4 and 6, the lens pushing device 8 is mounted on the upper surface of the base 11. The lens pushing device 8 is axially supported on the vertical surface of the column 82 by a horizontally mounted rectangular flat base plate 81, a vertical cylindrical body 82 mounted on the upper surface of the base plate 81, and movable in a vertical direction. The component is pushed into the shaft 83, and the component is pushed into the cylinder 84 in which the shaft 83 is moved in the vertical direction.
於零件推入軸83之下端安裝有推入透鏡L1之透鏡按壓頭85(參照圖7(c))。透鏡按壓頭85以硬金屬成形，經研磨加工而磨光表面。透鏡按壓頭85以節氣閥等控制氣缸84之空氣之壓力，以較透鏡吸附頭544大之按壓按壓組裝位置P5之組裝托板23之透鏡L1。然後，透鏡按壓頭85使透鏡L1密合鏡筒B之透鏡L1裝設孔B1之底面。圖7(c)顯示以透鏡按壓頭85使透鏡L1密合鏡筒B之透鏡L1裝設孔B1之底面的狀態。以大按壓力將透鏡L1按壓至鏡筒B之透鏡按壓頭85由於不需吸附透鏡L1來檢測透鏡L1之圖像，故可使用表面 經磨光之硬金屬。因而，由於即使以快速之按壓速度且較大之按壓力按壓，透鏡按壓頭85亦不致受到擠壓而變形，故透鏡L1之組裝精確度可穩定。又，由於可使按壓透鏡L1之速度快，故可縮短透鏡單元之組裝時間。 A lens pressing head 85 that pushes the lens L1 is attached to the lower end of the component pushing shaft 83 (see FIG. 7(c)). The lens pressing head 85 is formed of a hard metal and is polished to polish the surface. The lens pressing head 85 controls the pressure of the air of the air cylinder 84 by a throttle valve or the like, and presses the lens L1 of the assembly pallet 23 which is pressed against the assembly position P5 by a larger pressure than the lens suction head 544. Then, the lens pressing head 85 closes the lens L1 to the bottom surface of the lens L1 of the lens barrel B to mount the hole B1. Fig. 7(c) shows a state in which the lens L1 is brought into close contact with the bottom surface of the lens L1 of the lens barrel B by the lens pressing head 85. The lens pressing head 85 that presses the lens L1 to the lens barrel B with a large pressing force can detect the image of the lens L1 without adsorbing the lens L1, so the surface can be used. Polished hard metal. Therefore, since the lens pressing head 85 is not deformed by being pressed even with a rapid pressing speed and a large pressing force, the assembly accuracy of the lens L1 can be stabilized. Moreover, since the speed of pressing the lens L1 can be made fast, the assembly time of the lens unit can be shortened.
第3組裝站(2ST) 3rd assembly station (2ST)
就第3組裝站(3ST)之構造及組裝動作作說明。第3組裝站(3ST)是將遮光板S1(參照圖7(d))***組裝位置P6之組裝托板23之鏡筒B的組裝站。如圖1、圖3、圖6所示，第3組裝站(3ST)為與第1組裝站(1ST)完全相同之構造，以零件托盤供給排出裝置4、零件***裝置5、圖像檢測裝置61、托板定位裝置62、托板搬送裝置7構成。因而，在以下之說明中，關於與第1組裝站(1ST)相同之部份，省略詳細之說明。 The structure and assembly operation of the third assembly station (3ST) will be described. The third assembly station (3ST) is an assembly station for inserting the light shielding plate S1 (see FIG. 7(d)) into the lens barrel B of the assembly pallet 23 at the assembly position P6. As shown in FIG. 1, FIG. 3, and FIG. 6, the third assembly station (3ST) has the same structure as the first assembly station (1ST), and supplies the discharge device 4, the component insertion device 5, and the image detecting device to the component tray. 61. The pallet positioning device 62 and the pallet transporting device 7 are configured. Therefore, in the following description, the detailed description of the same portions as the first assembly station (1ST) will be omitted.
多個遮光板S1等間隔地收納於零件托盤供給排出裝置4之零件托盤41。零件***裝置5為X軸、Y軸、Z軸之3軸直角座標型機器人。由於遮光板S1之形狀為於旋轉方向對稱之形狀，故零件***裝置5無繞Z軸之旋轉軸θ軸。於零件***軸545(參照圖6)之下端安裝有將遮光板S1真空吸附而將之從零件托盤41搬送至組裝托板23之遮光板吸附頭546。遮光板吸附頭546在本例中為不鏽鋼製，亦可以黑色之合成樹脂(PEEK)成形。 The plurality of light shielding plates S1 are housed in the component tray 41 of the component tray supply and discharge device 4 at equal intervals. The part insertion device 5 is a 3-axis orthogonal coordinate type robot of the X-axis, the Y-axis, and the Z-axis. Since the shape of the light shielding plate S1 is a shape that is symmetrical in the rotational direction, the component insertion device 5 has no rotation axis θ about the Z axis. A light shielding plate suction head 546 that vacuum-adsorbs the light shielding plate S1 and transports it from the component tray 41 to the assembly pallet 23 is attached to the lower end of the component insertion shaft 545 (see FIG. 6). The visor adsorption head 546 is made of stainless steel in this example or black synthetic resin (PEEK).
以遮光板吸附頭546從零件托盤41所取出之遮光板S1搬入至組裝位置P6之組裝托板23，控制Z軸伺服馬達533之轉矩，以小按壓力將遮光板S1***至鏡筒B內。圖7(d)顯示將遮光板S1以小按壓力***至鏡筒B之狀態。遮光板S1 是使遮光板S1外徑相對於鏡筒B之內徑稍小，而形成鬆配合。因而，由於在本例之第3組裝站(3ST)之組裝位置P7不需遮光板S1之推入作業，故不進行推入作業。 The visor suction head 546 is carried into the assembly tray 23 of the assembly position P6 from the visor S1 taken out from the component tray 41, and the torque of the Z-axis servo motor 533 is controlled to insert the visor S1 into the lens barrel B with a small pressing force. Inside. Fig. 7 (d) shows a state in which the visor S1 is inserted into the barrel B with a small pressing force. Visor S1 The outer diameter of the visor S1 is made slightly smaller than the inner diameter of the lens barrel B to form a loose fit. Therefore, since the insertion operation of the light shielding plate S1 is not required at the assembly position P7 of the third assembly station (3ST) of this example, the pushing operation is not performed.
第4至第12組裝站(2至12ST) 4th to 12th assembly stations (2 to 12ST)
第4組裝站(4ST)至第12組裝站(12ST)之構造及組裝動作由於與上述第2組裝站(2ST)至第3組裝站(3ST)為實質上相同之構造、功能，故僅就其組裝動作之要點，簡單地說明。即，第4組裝站(4ST)是將透鏡L2***組裝位置P8之組裝托板23之鏡筒B並且在下個組裝位置P9推入組裝托板23之透鏡L2之組裝站。第5組裝站(5ST)是將遮光板S2***至組裝位置P10之組裝托板23之鏡筒B並且不對下個組裝位置P11之組裝托板23進行組裝作業的組裝站。 Since the structure and assembly operation of the fourth assembly station (4ST) to the twelfth assembly station (12ST) are substantially the same as those of the second assembly station (2ST) to the third assembly station (3ST), only The main points of the assembly operation are briefly explained. That is, the fourth assembly station (4ST) is an assembly station that inserts the lens L2 into the lens barrel B of the assembly tray 23 at the assembly position P8 and pushes the lens L2 of the assembly tray 23 at the next assembly position P9. The fifth assembly station (5ST) is an assembly station that inserts the light shielding plate S2 into the lens barrel B of the assembly tray 23 at the assembly position P10 and does not assemble the assembly pallet 23 of the next assembly position P11.
第6組裝站(6ST)是將透鏡L3***至組裝位置P12之組裝托板23之鏡筒B並且在下個組裝位置P13推入組裝托板23之透鏡L3的組裝站。在第6組裝站(6ST)之組裝作業完畢之組裝托板23以托板搬送裝置7搬送至左端之組裝位置P14後，以托板移送裝置3A從下側引導軌道21移送至上側引導軌道22。第7組裝站(7ST)以托板搬送裝置7將組裝托板23從左端之組裝位置P15經由組裝位置P16，搬送至組裝位置P17。之後，第7組裝站(7ST)是將遮光板S3***組裝位置P17之組裝托板23之鏡筒B並且不對下個組裝位置P18之組裝托板23進行組裝作業的組裝站。 The sixth assembly station (6ST) is an assembly station that inserts the lens L3 into the lens barrel B of the assembly tray 23 at the assembly position P12 and pushes the lens L3 of the assembly tray 23 at the next assembly position P13. The assembly pallet 23, which has been assembled by the sixth assembly station (6ST), is transported to the left end assembly position P14 by the pallet transport device 7, and then transferred from the lower guide rail 21 to the upper guide rail 22 by the pallet transfer device 3A. . The seventh assembly station (7ST) transports the assembly pallet 23 from the assembly position P15 at the left end to the assembly position P17 via the assembly position P16 by the pallet conveyance device 7. Thereafter, the seventh assembly station (7ST) is an assembly station that inserts the light shielding plate S3 into the lens barrel B of the assembly tray 23 at the assembly position P17 and does not assemble the assembly pallet 23 of the next assembly position P18.
第8組裝站(8ST)是將透鏡L4***至組裝位置P19之組裝托板23之鏡筒B並且推入下個組裝位置P20之組裝托 板23之透鏡L4的組裝站。第9組裝站(9ST)是將遮光板S4***組裝位置P21之組裝托板23之鏡筒B並且不對下個組裝位置P22之組裝托板23進行組裝作業的組裝站。 The eighth assembly station (8ST) is an assembly tray that inserts the lens L4 into the lens barrel B of the assembly tray 23 at the assembly position P19 and pushes it into the next assembly position P20. Assembly station for lens L4 of plate 23. The ninth assembly station (9ST) is an assembly station that inserts the visor S4 into the lens barrel B of the assembly pallet 23 at the assembly position P21 and does not assemble the assembly pallet 23 at the next assembly position P22.
第10組裝站(10ST)是將透鏡L5***至組裝位置P23之組裝托板23之鏡筒B並且推入下個組裝位置P24之組裝托板23之透鏡L5的組裝站。第11組裝站(11ST)是將以制動環吸附頭547(參照圖7(e))所吸附之制動環SR***至組裝位置P25之組裝托板23之鏡筒B。制動環SR是防止裝設於鏡筒B之透鏡及遮光板從鏡筒B脫落之零件。又，在下個組裝位置P26之組裝托板23檢測已完成之透鏡單元之高度。圖7(e)顯示於鏡筒B裝配有所有零件之完成品的透鏡單元之例。顯示圖7(d)與圖7(e)之間之組裝步驟的說明圖省略。第12組裝站(12ST)是從組裝位置P27之組裝托板23卸除合格品之透鏡單元將之搬出至零件托盤供給排出裝置4之合格品用零件托盤41並且卸除不合格品之透鏡單元將之搬出至不合格品用零件托盤41的組裝站。 The tenth assembly station (10ST) is an assembly station that inserts the lens L5 into the lens barrel B of the assembly tray 23 at the assembly position P23 and pushes it into the lens L5 of the assembly tray 23 at the next assembly position P24. The eleventh assembly station (11ST) is a lens barrel B that inserts the brake ring SR sucked by the brake ring suction head 547 (see FIG. 7(e)) into the assembly pallet 23 of the assembly position P25. The brake ring SR is a member that prevents the lens mounted on the lens barrel B and the light shielding plate from coming off the lens barrel B. Further, the assembly pallet 23 at the next assembly position P26 detects the height of the completed lens unit. Fig. 7(e) shows an example of a lens unit in which the lens barrel B is equipped with a finished product of all the parts. An explanatory diagram showing an assembly procedure between FIG. 7(d) and FIG. 7(e) is omitted. The 12th assembly station (12ST) is a lens unit that removes the defective lens unit from the assembly tray 23 at the assembly position P27 and carries it out to the qualified parts tray 41 of the component tray supply and discharge device 4, and removes the defective product. Move it out to the assembly station of the defective parts tray 41.
從組裝托板23卸除在第12組裝站(12ST)完成之透鏡單元後，以前述托板搬送裝置7將組裝位置P27之組裝托板23移動至組裝位置P28後，以托板移送裝置3B從上側引導軌道22移送至下側引導軌道21側，再次開始在第1組裝站(1ST)之組裝作業，返回組裝作業最初之步驟。 After the lens unit completed at the twelfth assembly station (12ST) is removed from the assembly pallet 23, the assembly pallet 23 of the assembly position P27 is moved to the assembly position P28 by the pallet conveyance device 7, and the pallet transfer device 3B is used. The upper guide rail 22 is transferred to the lower guide rail 21 side, and the assembly work at the first assembly station (1ST) is resumed, and the first step of the assembly operation is returned.
根據上述透鏡單元組裝裝置，由於吸附透鏡搬送後，使用以小按壓力***之合成樹脂製透鏡吸附頭與以較此小按壓力大之按壓力按壓透鏡之金屬製透鏡按壓頭2種 頭，分割各頭之組裝製程來同時進行，故可縮短透鏡單元之一組裝製程之組裝時間。又，由於合成樹脂透鏡吸附頭以小按壓力***透鏡，金屬製透鏡按壓頭以大按壓力按壓透鏡，故各頭不致受到擠壓而變形，故透鏡之組裝精確度穩定，各頭之耐久性也提高。 According to the lens unit assembly device described above, after the adsorption lens is transported, a synthetic lens lens adsorption head inserted at a small pressing force and a metal lens pressing head which presses the lens at a pressure greater than the small pressing force are used. The head and the assembly process of dividing the heads are simultaneously performed, so that the assembly time of one assembly process of the lens unit can be shortened. Moreover, since the synthetic resin lens adsorption head is inserted into the lens with a small pressing force, the metal lens pressing head presses the lens with a large pressing force, so that the heads are not deformed by being pressed, so that the assembly precision of the lens is stable, and the durability of each head is maintained. Also improved.
其他實施形態 Other embodiments
如圖7(b)所示，前述透鏡吸附頭544是***至透鏡L1呈輕微地放置於鏡筒B之透鏡L1裝設孔B1的入口之狀態之位置。即，透鏡L1是假組裝之狀態，並未***至鏡筒B之最終組裝位置、即透鏡L1裝設孔B1之預定位置。然而，藉透鏡吸附頭544，在此透鏡***製程中，亦可為將此透鏡L1***至透鏡L1裝設孔B1之預定最終組裝位置之方法。下個製程之透鏡按壓頭85在此透鏡L1之***製程，於透鏡L1未裝配於預定最終組裝位置時，使透鏡L1密合鏡筒B內之透鏡L1裝設孔B1之底面。換言之，透鏡按壓頭85之按壓動作為透鏡L1是否裝設於最終組裝位置之確認或更正製程。 As shown in Fig. 7 (b), the lens adsorption head 544 is inserted into a state where the lens L1 is slightly placed at the entrance of the lens L1 mounting hole B1 of the lens barrel B. That is, the lens L1 is in a state of dummy assembly, and is not inserted into the final assembly position of the lens barrel B, that is, the predetermined position of the lens L1 mounting hole B1. However, by the lens adsorption head 544, in the lens insertion process, a method of inserting the lens L1 into the lens L1 to mount the predetermined final assembly position of the hole B1 may be employed. The lens pressing head 85 of the next process is inserted into the lens L1, and when the lens L1 is not mounted at the predetermined final assembly position, the lens L1 is brought into close contact with the bottom surface of the lens L1 of the lens barrel B. In other words, the pressing operation of the lens pressing head 85 is a confirmation or correction process of whether or not the lens L1 is mounted at the final assembly position.
再者，前述合成樹脂製透鏡吸附頭544以小按壓力***透鏡，接著，金屬製透鏡按壓頭85以大按壓力按壓透鏡L1。然而，由於該等頭之材質因組裝零件之材質、形狀等而異，故非以此按壓條件限定。因而，按壓力也未必指最初用以***透鏡之按壓力小，將透鏡L1推入下個鏡筒B內之預定位置之透鏡推入裝置8的按壓力大。又，前述透鏡推入裝置8使用氣缸84，亦可使用步進馬達、AC伺服馬達、DC伺服馬達等伺服馬達取代此氣缸。 Further, the synthetic resin lens suction head 544 is inserted into the lens with a small pressing force, and then the metal lens pressing head 85 presses the lens L1 with a large pressing force. However, since the materials of the heads vary depending on the material, shape, and the like of the assembled parts, they are not limited by this pressing condition. Therefore, the pressing force does not necessarily mean that the pressing force for initially inserting the lens is small, and the pressing force of the lens pushing device 8 for pushing the lens L1 into the predetermined position in the next barrel B is large. Further, the lens pushing device 8 uses the air cylinder 84, and a servo motor such as a stepping motor, an AC servo motor, or a DC servo motor may be used instead of the cylinder.
前述透鏡單元組裝裝置1以下側引導軌道21及上側引導軌道22上之組裝托板23，將透鏡L1裝配於鏡筒B。即，在搬送線上將透鏡L1裝配於鏡筒B。然而，此裝配亦可不在搬送線上而是將鏡筒B移動至另外配置之組裝站來裝配透鏡L1等。因而，本發明所言及之搬送裝置為不僅包含搬送線也包含另外配置之組裝站的概念。 The lens unit assembly device 1 guides the assembly tray 23 on the lower side of the rail 21 and the upper guide rail 22, and attaches the lens L1 to the barrel B. That is, the lens L1 is attached to the barrel B on the conveyance line. However, the assembly may not be on the transport line but the lens barrel B may be moved to a separately assembled assembly station to assemble the lens L1 or the like. Therefore, the conveying apparatus mentioned in the present invention is a concept including not only a conveying line but also an assembly station separately arranged.
