本發明係關於一種透鏡研磨裝置，尤其是，關於適合具備使用頂針之透鏡研磨部之裝置構造之透鏡保持機構之構成。 The present invention relates to a lens polishing apparatus, and more particularly to a configuration of a lens holding mechanism suitable for a device having a lens polishing portion using a ejector.

作為透鏡研磨裝置，一般有具備使用頂針(pin)之研磨機構者。此種研磨裝置例如構成為，藉由於安裝在可旋轉地構成之研磨軸之上端之下研磨盤上隔著透鏡配置上研磨盤，且將頂針可旋轉自如且可角度自如地連結於上研磨盤，並一方面使此頂針於水平方向擺動一方面使研磨軸旋轉，對透鏡均勻地進行研磨(例如，參照以下之專利文獻1)。 As the lens polishing device, there is generally a polishing mechanism using a pin. Such a polishing apparatus is configured, for example, by arranging a grinding disc with a lens disposed on a grinding disc below the upper end of the rotatably formed grinding shaft, and rotatably and arrangably attaching the ejector pin to the upper grinding disc On the other hand, the thimble is oscillated in the horizontal direction, and the polishing shaft is rotated to uniformly polish the lens (for example, refer to Patent Document 1 below).

為了對如上述之研磨裝置自動地供給透鏡、或自動地將研磨後之透鏡排出，提出一種自動交接機構，其具備安裝頭，該安裝頭具有可旋轉之頭軸14a，該頭軸14a具備對貼附有作為研磨對象之透鏡之上盤3進行吸附保持之一對吸附軸15、16，於收容上盤3之托板(pallet)20與複數之研磨機之間進行上盤3之供給及回收(例如，參照以下之專利文獻2)。 In order to automatically supply a lens to the polishing apparatus as described above or to automatically discharge the polished lens, an automatic transfer mechanism is provided which is provided with a mounting head having a rotatable head shaft 14a having a pair Attached to the lens upper surface of the lens 3 as an object to be polished, the pair of adsorption axes 15 and 16 are attached, and the upper tray 3 is supplied between the pallet 20 for accommodating the upper tray 3 and a plurality of grinders.

然而，上述習知之自動交接機構，僅為對藉由樹脂等黏著、固定有作為研磨對象之透鏡之上盤3(透鏡保持器)進行搬送之機構而已，無法與上盤3分開對作為研磨對象之透鏡進行供給及回收，因而另外需要有於研磨處理之前後對上盤3(透鏡保持器)之透鏡之拆裝作業，並於依序對透鏡之表背面進行研磨之情況下，需要於每個步驟進行上述之拆裝作業，因而有無法高效率地進行透鏡研磨，且研磨步驟之自動化也困難之問題。 However, the above-described automatic transfer mechanism is only a mechanism for transporting the lens upper disc 3 (lens holder) to be adhered by resin or the like, and is not separated from the upper tray 3 as an object to be polished. Since the lens is supplied and recovered, it is necessary to disassemble the lens of the upper tray 3 (lens holder) before and after the polishing process, and in the case of sequentially grinding the front and back surfaces of the lens, it is necessary to In the above steps, the above-described disassembly and assembly work is performed, so that there is a problem that lens polishing cannot be performed efficiently, and automation of the polishing step is also difficult.

因此，本發明係用以解決上述問題者，其目的在於實現一種透鏡保持機構及使用其之透鏡研磨裝置，即使不預先將透鏡固定或安裝於透鏡保持器，仍可自動地進行透鏡之供給及回收。 Accordingly, the present invention has been made to solve the above problems, and an object thereof is to realize a lens holding mechanism and a lens polishing apparatus using the same, which can automatically supply a lens even if the lens is not fixed or attached to the lens holder in advance.

It is located at a position corresponding to the above-described holder holding surface 21c of the head body 21B. The held surface 6a faces the adsorption opening 21ea of the adsorption head 21, and the held surface 6a is adsorbed and held by the holding surface 21c by the adsorption force, which is absorbed by the holder suction hole 21e. The suction is generated in the annular region surrounded by the sealing members 21g and 21h in the adsorption opening portion 21ea and its surroundings. Further, a concave thimble connecting portion 6b is formed inside the held surface 6a of the lens holder 6 at a position corresponding to the openings 21Aa and 21Ba of the adsorption head 21.

保持器框體6B整體構成為環狀，且嵌合於上述保持器基體6A之構成為略小徑之下部外周，於此狀態下藉由平頭螺釘等之鎖緊構件6e固定於保持器基體6A。此保持器框體6B係具備對吸附保持於保持器基體6A之透鏡保持面6c上之透鏡2a之外周進行保持之功能。以保持器框體6B係以由不容易對透鏡2a及研磨構件17造成損傷之原材料、例如尼龍等之合成樹脂所構成為較佳。不過，也可將保持器基體6A與保持器框體6B一體地構成。保持器基體6B之內周下緣6f係朝上述透鏡保持面6c之周圍下方突出，且於研磨時保持透鏡2a以使其不要自透鏡保持器6之透鏡保持面6c下方脫落。此外，形成於上述內周下緣6f之外周側之下面部6g，係以透鏡保持器6於研磨時一面保持透鏡2a一面平滑地移動於上述研磨構件17之研磨面(未圖示)上之方式，形成為沿該研磨面之面形狀、或者不干擾上述研磨面之面形狀。 The holder frame 6B is formed in a ring shape as a whole, and is configured to be fitted to the holder base 6A so as to have a slightly smaller outer circumference. In this state, the holder member 6e is fixed to the holder base 6A by a locking member 6e such as a grub screw. . This holder frame 6B has a function of holding the outer circumference of the lens 2a that is held by the lens holding surface 6c of the holder base 6A. It is preferable that the holder frame 6B is made of a material which is not easily damaged by the lens 2a and the polishing member 17, for example, a synthetic resin such as nylon. However, the holder base 6A and the holder frame 6B may be integrally formed. The inner peripheral lower edge 6f of the holder base 6B protrudes downward from the periphery of the lens holding surface 6c, and holds the lens 2a so as not to fall off from the lens holding surface 6c of the lens holder 6 during polishing. Further, the peripheral surface lower surface portion 6g formed on the outer peripheral lower edge 6f is formed by moving the lens holder 2a on the polishing surface (not shown) of the polishing member 17 while the lens holder 6 is being held while polishing. The form is formed along the surface shape of the polishing surface or does not interfere with the surface shape of the polishing surface.

於透鏡保持器6(保持器框體6B)之上述頂針連結部 6b之周圍形成有朝上側(壓接頭21之側)突出之環狀之凸框部6h，此凸框部6h之外周面成為以朝上方縮徑之方式而構成之錐面6i。此錐面6i係成為與設置在吸附頭21之開口部21Ba之下側開口緣之倒錐面21i嵌合之形狀，具備當透鏡保持器6之被保持面6a被吸附保持於吸附頭21之保持器保持面21c時，以透鏡保持器6之軸心與吸附頭21之軸心約略一致之方式進行導引之功能。實際上，上述保持器保持面21c與被保持面6a係經由密封材21f~21h而被吸附，因而，當具有藉由介設吸附保持狀態下之密封材21f~21h而產生於保持器保持面21c與被保持面6a間之間隔時，吸附頭21與透鏡保持器6之上述兩軸心，係藉由被倒錐面21i對錐面6i進行導引，而匹配成為對頂針軸26之前端部與透鏡保持器6之頂針連結部之***及嵌合無障礙之程度。 The thimble connecting portion of the lens holder 6 (the holder frame 6B) An annular convex frame portion 6h that protrudes toward the upper side (the side of the press joint 21) is formed around the periphery of 6b, and the outer peripheral surface of the convex frame portion 6h is a tapered surface 6i that is formed to be reduced in diameter upward. The tapered surface 6i has a shape that fits into the inverted tapered surface 21i provided on the lower opening edge of the opening 21Ba of the adsorption head 21, and is provided so that the held surface 6a of the lens holder 6 is adsorbed and held by the adsorption head 21. When the holder holding surface 21c is held, the function of guiding is performed such that the axis of the lens holder 6 approximately coincides with the axis of the adsorption head 21. In fact, the holder holding surface 21c and the held surface 6a are adsorbed via the sealing members 21f to 21h, and thus are provided on the holder holding surface 21c by the sealing members 21f to 21h which are placed in the adsorption holding state. The distance between the suction head 21 and the lens holder 6 is guided by the inverted tapered surface 21i to the tapered surface 6i, and is matched to the front end of the ejector shaft 26. The degree of insertion and fitting of the ejector coupling portion with the lens holder 6 is unobstructed.

依上述方式構成之吸附頭21，係藉由通過上述保持器吸引孔21e進行吸引，而可吸附保持透鏡保持器6。此時，吸附頭21之保持器保持面21c與透鏡保持器6之被保持面6a，係經由密封材21f、21g、21h而對向配置，藉由密封材21g及21h氣密性地構成保持器吸引孔e與被保持面6a所對向之區域，藉此，基於通過上述保持器吸引孔21e之吸引力產生對透鏡保持器6之吸附力。此外，吸引連接孔21d與吸引孔6d對向之區域，也藉由密封材21f及21g而氣密性地構成。因此，吸附保持件21係於吸附保持透鏡保持器6之狀態下，藉由通過上述吸引連接孔21d進行吸引，可通過連通於上述吸引連接孔21d之透鏡保持器6之吸引孔6d來吸附保持透鏡2a。於此情況下，透鏡2a係於密接於透鏡保持器6之透鏡保持面2c之狀態下被吸附保持。此時，被吸附保持之透鏡 2a之外周緣，係成為由上述保持器框體6B之內周下緣6f自周圍所圍繞之狀態。 The adsorption head 21 configured as described above can suck and hold the lens holder 6 by suction through the holder suction hole 21e. At this time, the holder holding surface 21c of the adsorption head 21 and the held surface 6a of the lens holder 6 are opposed to each other via the sealing members 21f, 21g, and 21h, and are hermetically held by the sealing members 21g and 21h. The suction hole e is opposed to the region facing the held surface 6a, whereby the suction force to the lens holder 6 is generated based on the suction force passing through the above-described holder suction hole 21e. Further, the region where the suction connection hole 21d and the suction hole 6d face each other is also hermetically formed by the sealing members 21f and 21g. Therefore, the suction holding member 21 is sucked and held by the suction connection hole 21d in a state where the adsorption holding member 21 is attached to the suction holding lens holder 6, and can be sucked and held by the suction hole 6d of the lens holder 6 that communicates with the suction connection hole 21d. Lens 2a. In this case, the lens 2a is suction-held in a state in which it is in close contact with the lens holding surface 2c of the lens holder 6. At this time, the lens that is adsorbed and held The outer periphery of 2a is in a state of being surrounded by the inner peripheral lower edge 6f of the holder frame 6B from the periphery.

再者，上述透鏡保持器6係具有與透鏡2a之表面形狀及研磨構件17之研磨面對應之(無障礙)透鏡保持面6c、內周下緣6f及下面部6g。例如，也可如圖7(a)及(b)所示之保持器基體6A’、6A”那樣構成為，配合吸附保持之透鏡2a之表面形狀及平面尺寸，將上述透鏡保持面6c如6c’、6c”那樣形成為不同之曲面形狀、不同之外徑。再者，圖7(c)於尺寸上雖多少有些差異但基本上係與上述保持器基體6A、6A’、6A”為共通之俯視圖。此外，也可如圖8(a)及(b)所示之保持器框體6B’、6B”那樣構成為，配合透鏡2a之厚度及平面尺寸，將上述內周下緣6f如6f’、6f”那樣形成為不同之突出量及不同之半徑位置，或者，配合研磨構件17之研磨面之形狀，將下面部6g如6g’、6g”那樣形成為不同之面形狀。再者，圖8(c)於尺寸上雖多少有些差異但基本上係與上述保持器框體6B、6B’、6B”為共通之俯視圖。 Further, the lens holder 6 has a (barrier-free) lens holding surface 6c, an inner peripheral lower edge 6f, and a lower surface portion 6g corresponding to the surface shape of the lens 2a and the polishing surface of the polishing member 17. For example, as shown in FIGS. 7(a) and 7(b), the lens holder 6A' and 6A' may be configured such that the lens holding surface 6c is 6c, in accordance with the surface shape and the planar size of the lens 2a for adsorption holding. ', 6c' is formed into different curved shapes and different outer diameters. Further, Fig. 7(c) is a plan view common to the above-described holder bases 6A, 6A', and 6A" although somewhat different in size. Alternatively, as shown in Figs. 8(a) and (b). The retainer housings 6B' and 6B" are configured such that the inner peripheral lower edge 6f is formed into different projection amounts and different radial positions as the 6f' and 6f" of the lens 2a in accordance with the thickness and the planar size. Alternatively, in accordance with the shape of the polishing surface of the polishing member 17, the lower portion 6g is formed into a different surface shape as in the case of 6g', 6g". Further, Fig. 8(c) is a plan view which is common to the above-described holder frames 6B, 6B', and 6B" although the size is somewhat different.

Directly above 20P. Further, the adsorption head 21 is lowered by the adsorption head elevation drive unit 22, and as shown in FIG. 9, the delivery position P is opposed to the lower transfer head 31.

在此，於吸附頭21預先吸附保持有透鏡保持器6及透鏡2a(例如，研磨完成之透鏡)之情況下，於搬送頭31使搬送頭31之未保持透鏡之透鏡保持部例如第2透鏡保持部31B朝向上方(吸附頭21側)，將未保持於吸附頭21之透鏡2a移載於該第2透鏡保持部31B。其後，吸附頭21藉由吸附頭升降驅動部22暫時上升而自第2透鏡保持部31B分離，於此期間，搬送頭31藉由搬送頭旋轉驅動部32而翻轉，將保持自透鏡托板2搬送來之透鏡2a之第1透鏡保持部31A朝向吸附頭21側。並且，若吸附頭21再次下降，第1透鏡保持部31A將搬送來之透鏡2a開放，藉此，透鏡2a被吸附頭21所吸附保持及移載。又，如上述，於移動至正上方位置20P之吸附頭21僅保持透鏡保持器6，而不保持透鏡2a之情況下，不進行如上述般將透鏡朝第2透鏡保持部31B之移載，而立即將保持於第1透鏡保持部31A之透鏡2a朝吸附頭21側移動。其後，如圖10所示，吸附頭21藉由吸附頭升降驅動部22再次上升，自搬送頭31分離。再者，其後，搬送頭31返回後方位置，於如上述那樣具有自吸附頭21側接取之透鏡2a之情況下，將該透鏡2a朝向透鏡托板2及其他透鏡研磨單元搬送。 When the lens holder 6 and the lens 2a (for example, the lens that has been polished) are adsorbed and held in advance by the adsorption head 21, the lens holding portion of the transfer head 31 that does not hold the lens, for example, the second lens, is transported to the transfer head 31. The holding portion 31B faces upward (on the side of the adsorption head 21), and the lens 2a that is not held by the adsorption head 21 is transferred to the second lens holding portion 31B. Thereafter, the adsorption head 21 is temporarily separated from the second lens holding portion 31B by the suction head lifting/lowering driving portion 22, and during this period, the conveying head 31 is reversed by the conveying head rotation driving portion 32, and is held from the lens holder. (2) The first lens holding portion 31A of the lens 2a that has been transported faces the side of the adsorption head 21. When the adsorption head 21 is lowered again, the first lens holding portion 31A opens the lens 2a that has been transported, whereby the lens 2a is sucked and held by the adsorption head 21. Further, as described above, when the adsorption head 21 moved to the immediately upper position 20P holds only the lens holder 6, and does not hold the lens 2a, the lens is not transferred to the second lens holding portion 31B as described above. Immediately, the lens 2a held by the first lens holding portion 31A is moved toward the adsorption head 21 side. Thereafter, as shown in FIG. 10, the adsorption head 21 is lifted again by the adsorption head elevation drive unit 22, and is separated from the transfer head 31. Then, the transport head 31 is returned to the rear position, and when the lens 2a picked up from the side of the adsorption head 21 is provided as described above, the lens 2a is transported toward the lens holder 2 and the other lens polishing unit.

如上述，若吸附頭21接取新的透鏡2a，如圖10所示，吸附頭21藉由吸附頭升降驅動部22自上述交接位置P上升(返回交接位置20P)，其後，藉由供給回收單元前後驅動部25朝向前方移動，配置於圖4所示之研磨軸12之正上方位置20Q(圖示虛線)。於此狀態下，如圖11所示，頂針軸保持器23藉由供給回收 單元升降驅動部24與吸附頭21一起下降。並且，如圖12所示，吸附頭21藉由吸附頭升降驅動部22再次下降而配置於供給回收位置Q，該供給回收位置Q係以吸附保持之透鏡保持器6及透鏡2a配置於研磨構件17之研磨面上之方式而設定(參照圖4，圖示虛線)。再者，於上述過程中，當吸附頭21將透鏡2a與透鏡保持器6一起吸附保持時，控制部7產生經由吸引連接孔21d及保持器吸引孔21e之吸附作用，當吸附頭21吸附保持透鏡保持器6但未保持透鏡2a時，控制部7維持經由保持器吸引孔21e之吸附作用，但停止經由吸引連接孔21d之吸附作用，不產生經由透鏡保持器6之透鏡吸引孔6d之吸附力。 As described above, when the adsorption head 21 picks up the new lens 2a, as shown in FIG. 10, the adsorption head 21 rises from the transfer position P by the adsorption head elevation drive unit 22 (returns to the transfer position 20P), and thereafter, by the supply. The recovery unit front and rear drive unit 25 moves forward, and is disposed at a position directly above the polishing shaft 12 shown in FIG. 4 at a position 20Q (broken line in the figure). In this state, as shown in FIG. 11, the thimble shaft holder 23 is recovered by supply. The unit lifting drive unit 24 is lowered together with the adsorption head 21. Further, as shown in FIG. 12, the adsorption head 21 is placed at the supply recovery position Q by the adsorption head elevation drive unit 22, and the supply recovery position Q is disposed on the polishing member by the lens holder 6 and the lens 2a that are adsorbed and held. The method is set on the surface of the polishing surface of 17 (see FIG. 4, a broken line is shown). Further, in the above process, when the adsorption head 21 adsorbs and holds the lens 2a together with the lens holder 6, the control portion 7 generates adsorption by the suction connection hole 21d and the holder suction hole 21e, and the adsorption head 21 is adsorbed and held. When the lens holder 6 does not hold the lens 2a, the control unit 7 maintains the adsorption action via the holder suction hole 21e, but stops the adsorption through the suction connection hole 21d, and does not cause the adsorption of the lens suction hole 6d via the lens holder 6. force.

於上述供給回收位置Q上，被吸附頭21所吸附保持之透鏡保持器6及透鏡2a係配置在研磨構件17之研磨面上。此時，由於在透鏡保持器6之內周下緣6f與研磨面之間保持透鏡2a，透鏡保持器6之下面部6g成為沿研磨構件17之研磨面之形狀(或者與研磨面不干涉之形狀)，因而，透鏡保持器6及透鏡2a可平滑地移動於上述研磨面上。惟此時，由於透鏡保持器6及透鏡2a被吸附保持於吸附頭21，因而，透鏡保持器6及透鏡2a之研磨面上之位置處於被固定之狀態。於是，於此狀態下使經由吸引連接孔21d及保持器吸引孔21e之吸引作用停止，且於此吸引路徑中進行周知之真空破壞，藉以將保持於吸附頭21上之透鏡保持器6及透鏡2a開放。被開放之透鏡保持器6及透鏡2a被載置於研磨構件17之研磨面上。又，此時，頂針軸26之前端部26a尚未配置於吸附頭21之上方。 The lens holder 6 and the lens 2a which are adsorbed and held by the adsorption head 21 are disposed on the polishing surface of the polishing member 17 at the supply/recovery position Q. At this time, since the lens 2a is held between the inner peripheral lower edge 6f of the lens holder 6 and the polishing surface, the lower surface portion 6g of the lens holder 6 has a shape along the polishing surface of the polishing member 17 (or does not interfere with the polished surface). The shape), therefore, the lens holder 6 and the lens 2a can be smoothly moved on the above-mentioned polishing surface. However, at this time, since the lens holder 6 and the lens 2a are adsorbed and held by the adsorption head 21, the positions of the lens holder 6 and the lens 2a on the polishing surface are fixed. Then, in this state, the suction action through the suction connection hole 21d and the holder suction hole 21e is stopped, and the known vacuum breakage is performed in the suction path, whereby the lens holder 6 and the lens held on the adsorption head 21 are held. 2a is open. The opened lens holder 6 and the lens 2a are placed on the polishing surface of the polishing member 17. Further, at this time, the front end portion 26a of the ejector shaft 26 is not disposed above the adsorption head 21.

其後，藉由頂針軸驅動部27使頂針軸26自頂針軸保 持部23下降，如圖13所示，通過研磨構件17上之吸附頭21之上述開口部21Aa及開口部21Ba使前端部26a嵌合於透鏡保持器6之上述頂針連結部6b。此時，由於被開放之透鏡保持器6連結於頂針軸26，因而透鏡保持器6及透鏡2a成為藉由頂針軸26被保持於研磨構件17之研磨面上之狀態。並且，如圖14所示，吸附頭21藉由吸附頭升降驅動部22自透鏡保持器6離開並上升。然後，藉由開閉驅動機構16a將罩板16封閉，開始進行研磨步驟。 Thereafter, the ejector shaft 26 is secured from the ejector pin by the ejector pin drive portion 27. The holding portion 23 is lowered, and as shown in FIG. 13, the distal end portion 26a is fitted to the thimble connecting portion 6b of the lens holder 6 by the opening portion 21Aa and the opening portion 21Ba of the adsorption head 21 on the polishing member 17. At this time, since the opened lens holder 6 is coupled to the ejector shaft 26, the lens holder 6 and the lens 2a are held by the ejector shaft 26 on the polishing surface of the polishing member 17. Further, as shown in FIG. 14, the adsorption head 21 is separated from the lens holder 6 by the adsorption head elevation drive unit 22 and raised. Then, the cover plate 16 is closed by the opening and closing drive mechanism 16a, and the polishing step is started.

由透鏡研磨部10進行之研磨步驟，係於圖14所示之狀態下，藉由一方面利用研磨軸旋轉驅動部13使研磨軸12旋轉，一方面藉由供給回收單元前後驅動部25使頂針軸26前後進出，而於規定之行程範圍內往返動作所進行。此時，由於透鏡保持器6係相對於頂針軸26可旋轉且可變更角度地連結，因而與藉由保持器框體6B所保持之透鏡2a一起沿研磨構件17之研磨面進行擺動。於此研磨步驟中，頂針軸驅動部27經由透鏡保持器6對透鏡2a施加規定之研磨壓力，將頂針軸26朝下方按壓。為了能正確地設定此時之研磨壓力或進行詳細調整，以頂針軸驅動部27係由可調整加壓力之氣筒等之汽缸構造所構成為較佳。研磨壓力係控制為於研磨步驟之初期階段較低，然後增大或與時間一起漸漸地增大為較佳。例如，也可以與時間一起改變研磨壓力之方式，預先於研磨單元控制部7等中至少依照2~3個階段設定研磨壓力。頂針軸26之擺動速度、擺動範圍、擺動周期、研磨壓力等，係根據預先設定之時間日程而藉由控制部7所控制。 The polishing step by the lens polishing unit 10 is performed in the state shown in FIG. 14 by rotating the polishing shaft 12 by the polishing shaft rotation driving portion 13 on the one hand, and the ejector pin is provided by the front and rear driving portion 25 of the supply recovery unit. The shaft 26 is moved forward and backward, and the reciprocating motion is performed within a predetermined stroke range. At this time, since the lens holder 6 is rotatably and angularly coupled to the ejector shaft 26, it is oscillated along the polishing surface of the polishing member 17 together with the lens 2a held by the holder frame 6B. In this polishing step, the ejector shaft driving unit 27 applies a predetermined polishing pressure to the lens 2a via the lens holder 6, and presses the ejector shaft 26 downward. In order to accurately set the polishing pressure or the detailed adjustment at this time, it is preferable that the ejector pin drive unit 27 is constituted by a cylinder structure such as a gas cylinder capable of adjusting the pressure. The grinding pressure is controlled to be lower in the initial stage of the grinding step, and then increased or gradually increased with time to preferably. For example, the polishing pressure may be changed in accordance with the time, and the polishing pressure may be set in at least two or three stages in advance in the polishing unit control unit 7 or the like. The swing speed, the swing range, the swing period, the polishing pressure, and the like of the ejector shaft 26 are controlled by the control unit 7 in accordance with a preset time schedule.

當上述研磨步驟結束時，停止研磨軸12之旋轉，藉由開16a將罩板16開放。然後，藉由吸附頭升降驅動部22使吸附 頭21下降，如圖13所示，將透鏡保持器6移動至可吸附之供給回收位置Q。然後，如圖12所示，藉由頂針軸驅動部27使頂針軸26朝上方上升。然後，吸附頭21對透鏡保持器6及透鏡2a進行吸附保持。又，也可與上述不同，於使頂針軸26上升前，開始吸附頭21之吸附保持，但為了能確實地藉由吸附頭21進行對透鏡保持器6及透鏡2a之吸附保持，以於吸附頭21開始吸附保持之前，將頂針軸26之加壓狀態解除或將加壓力降低為較適。 When the above grinding step is completed, the rotation of the grinding shaft 12 is stopped, and the cover panel 16 is opened by the opening 16a. Then, the adsorption head 22 is used to lift the adsorption portion 22 The head 21 is lowered, as shown in Fig. 13, the lens holder 6 is moved to the adsorbable supply recovery position Q. Then, as shown in FIG. 12, the ejector shaft 26 is raised upward by the ejector shaft driving unit 27. Then, the adsorption head 21 adsorbs and holds the lens holder 6 and the lens 2a. Further, unlike the above, the adsorption holding of the adsorption head 21 may be started before the ejector shaft 26 is raised. However, in order to reliably adsorb and hold the lens holder 6 and the lens 2a by the adsorption head 21, it is possible to adsorb. Before the head 21 starts the adsorption holding, the pressurization state of the ejector shaft 26 is released or the pressing force is lowered to be appropriate.

其後，如圖11所示，吸附頭21藉由吸附頭升降驅動部22與透鏡保持器6及透鏡2a一起上升，再藉由供給回收單元升降驅動部24配置於上述正上方位置20Q。然後，藉由供給回收單元前後驅動部25使透鏡供給回收單元20朝向後方移動，將吸附頭21移動至圖4所示之正上方位置20P(圖中虛線)，並如圖10所示，使透鏡搬送單元30前進而將搬送頭31配置於其正下方。並且，如圖9所示，使吸附頭21移動至交接位置P(圖中虛線)，執行與上述同樣之透鏡2a之交接。 Thereafter, as shown in FIG. 11, the adsorption head 21 is raised by the adsorption head elevation drive unit 22 together with the lens holder 6 and the lens 2a, and is further disposed at the upper right position 20Q by the supply recovery unit elevation drive unit 24. Then, the lens supply and recovery unit 20 is moved backward by the supply/recovery unit front and rear drive unit 25, and the adsorption head 21 is moved to the position directly above the position 20P (broken line in the figure) shown in FIG. 4, and as shown in FIG. The lens transport unit 30 advances and arranges the transport head 31 directly below. Then, as shown in Fig. 9, the adsorption head 21 is moved to the delivery position P (broken line in the figure), and the same lens 2a as described above is transferred.

本實施形態中，構成為可於各透鏡研磨單元1A~1D中分別實施上述動作。並且，構成為藉由透鏡搬送單元30於各透鏡研磨單元1A~1D與托板收容部1E之間進行透鏡2a之搬送，藉此可實施各種之透鏡研磨處理。亦即，藉由透鏡搬送單元30之自透鏡托板2之透鏡2a之取出及朝向透鏡托板2之透鏡2a的收容、藉由透鏡搬送單元30之朝各透鏡研磨單元1A~1D之透鏡2a的供給及自各透鏡研磨單元1A~1D之透鏡2a的回收、透鏡研磨單元1A~1D與托板收容部1E之間、暨各透鏡研磨單元1A~1D之間之透鏡的搬送等。此外，作為研磨處理之態樣，例如，於自托板收容 部1E實施了在透鏡定位單元40之透鏡2a之位置修正後，將透鏡2a朝透鏡研磨單元1A供給且實施粗研磨，其後，結束了粗研磨之透鏡2a於再次受到透鏡定位單元40之位置修正後，朝透鏡研磨單元1B供給，即可接受精研磨。此外，也可於以透鏡研磨單元1A或1B對透鏡2a之其中一面進行研磨之後，於透鏡翻轉單元50中使透鏡2a翻轉後，再以透鏡研磨單元1C或1D對透鏡2a之另一面進行研磨。 In the present embodiment, the above-described operations can be performed in each of the lens polishing units 1A to 1D. Further, the lens transport unit 30 is configured to transport the lens 2a between the lens polishing units 1A to 1D and the pallet housing portion 1E, whereby various lens polishing processes can be performed. That is, the lens 2a from the lens holder 2 and the lens 2a facing the lens holder 2 are accommodated by the lens transport unit 30, and the lens 2a of the lens polishing units 1A to 1D is moved by the lens transport unit 30. The supply and the recovery of the lens 2a from each of the lens polishing units 1A to 1D, the transfer of the lens between the lens polishing units 1A to 1D and the pallet housing portion 1E, and the lens polishing units 1A to 1D. In addition, as a state of the grinding process, for example, in the tray receiving After the position correction of the lens 2a of the lens positioning unit 40 is performed, the lens 1a is supplied to the lens polishing unit 1A and rough grinding is performed, and thereafter, the lens 2a of the rough polishing is again subjected to the position of the lens positioning unit 40. After the correction, the lens polishing unit 1B is supplied to receive the fine polishing. Further, after the lens 2a is polished by the lens polishing unit 1A or 1B, the lens 2a may be inverted in the lens reversing unit 50, and then the other surface of the lens 2a may be ground by the lens polishing unit 1C or 1D. .

本實施形態中，以透鏡保持器6預先被吸附保持於吸附頭21為前提進行了說明，惟由於透鏡保持器6基本上需要根據透鏡2a及研磨構件17之研磨面來進行更換，因而只要藉由透鏡保持器6對吸附頭21之安裝作業來適宜地交換即可。於此情況下，如圖4所示，藉由將吸附頭21設為比上述正上方位置20Q朝向更前方配置之狀態，即可容易地進行上述作業。此外，研磨構件17之對研磨軸12之安裝作業也可適宜地進行。惟與上述透鏡2a之交接動作同樣地，也可藉由透鏡搬送單元30搬送透鏡保持器6，並交接給吸附頭21，或者也可另外設置保持器搬送單元，藉由此保持器搬送單元對吸附頭21交接透鏡保持器6，藉此可自動地供給、回收或者交換透鏡保持器6。再者，於可交換地構成透鏡保持器6之情況下，以於上述保持器搬送單元設置具備與上述搬送頭31類似之2個透鏡保持部之搬送頭為較佳。 In the present embodiment, the lens holder 6 is previously adsorbed and held by the adsorption head 21, but the lens holder 6 basically needs to be replaced by the polishing surface of the lens 2a and the polishing member 17, so that it is only necessary to borrow The attachment work of the adsorption head 21 by the lens holder 6 may be appropriately exchanged. In this case, as shown in FIG. 4, the above-described work can be easily performed by placing the adsorption head 21 in a state of being disposed further forward than the above-described upper position 20Q. Further, the attachment work of the polishing member 17 to the polishing shaft 12 can be suitably performed. Similarly to the above-described operation of the lens 2a, the lens holder 6 may be transported by the lens transport unit 30 and delivered to the adsorption head 21, or a holder transport unit may be separately provided, whereby the holder transport unit may be provided. The adsorption head 21 is delivered to the lens holder 6, whereby the lens holder 6 can be automatically supplied, recovered or exchanged. In the case where the lens holder 6 is configured to be interchangeable, it is preferable to provide a transfer head having two lens holding portions similar to the transfer head 31 in the holder transport unit.

又，本發明之透鏡研磨裝置，不僅限於上述圖示例，只要未超出本發明之實質範圍，當然可添加各種之變更。例如，上述實施形態中，對具備使用頂針軸26之上軸擺動型之透鏡研磨單元之透鏡研磨裝置之例子進行了說明，惟即使為具備其他形式之透 鏡研磨單元之透鏡研磨裝置，若為對上述吸附頭21、透鏡保持器6及透鏡2a可利用同樣之吸附保持態樣之裝置，仍可廣泛應用。此外，透鏡2a及透鏡保持器6之移動範圍只要是在交接位置P與供給回收位置Q之間即可。因此，也可不像上述實施形態那樣於交接位置P進行來自另一透鏡搬送單元之透鏡之接取或交遞，而是自透鏡托板2直接接取透鏡、或者對透鏡托板2直接交遞透鏡。此外，也可不像上述實施形態那樣使供給回收位置Q位於透鏡研磨部10之研磨構件17之研磨面上，而為另外設置於透鏡研磨部之內部之朝透鏡交接機構之供給及該自該透鏡交接機構之回收。 Further, the lens polishing apparatus of the present invention is not limited to the above-described example of the drawings, and various modifications may be added without departing from the scope of the invention. For example, in the above-described embodiment, an example of a lens polishing apparatus including a lens polishing unit that uses an axis swing type of the ejector shaft 26 has been described, but even if it has other forms The lens polishing apparatus of the mirror polishing unit can be widely applied as long as it can use the same adsorption holding state for the adsorption head 21, the lens holder 6, and the lens 2a. Further, the movement range of the lens 2a and the lens holder 6 may be between the delivery position P and the supply recovery position Q. Therefore, instead of picking up or handing over the lens from the other lens transport unit at the delivery position P as in the above embodiment, the lens may be directly taken from the lens holder 2 or directly delivered to the lens holder 2. lens. Further, the supply/recovery position Q may not be located on the polishing surface of the polishing member 17 of the lens polishing unit 10 as in the above embodiment, but may be supplied to the lens delivery mechanism and provided inside the lens polishing unit.
