Description
本発明は、保持方法、加工方法及び保持装置に関する。
The present invention relates to a holding method, a processing method, and a holding device.
薄型の光学素子を加工する際に、かかる光学素子、即ち、被保持物を、アロイなどの接着剤を用いてヤトイに接着して固定する技術が提案されている（特許文献１参照）。但し、特許文献１に開示された技術は、被保持物に対して高精度な加工が要求される場合、被保持物とヤトイとの接着面の形状精度や接着剤の厚さを厳重に管理しなければならないため、その実現が非常に困難である。
A technology has been proposed in which, when processing a thin optical element, such an optical element, that is, the object to be held, is adhered and fixed to the yatoy using an adhesive such as an alloy (see Patent Document 1). However, the technique disclosed in Patent Document 1 strictly manages the shape accuracy of the bonding surface between the object to be held and the toy and the thickness of the adhesive when high-precision processing is required for the object to be held. Must be done, which is very difficult to achieve.
また、被保持物は、自身からは接着時の自重による変形や接着面や接着面の形状誤差の影響を、ヤトイからは接着面の形状誤差の影響を、接着剤からは厚さむらの影響を受けるため、歪んだ状態でヤトイに接着（固定）される。被保持物が歪んだ状態でヤトイに接着されると、被保持物に対して高精度な加工を行ったとしても、加工後に被保持物をヤトイから剥がす際に接着時の歪みが復元してしまう。
In addition, the held object itself is affected by deformation due to its own weight at the time of bonding and the shape error of the bonding surface and the bonding surface, from the yatoi the shape error of the bonding surface, and from the adhesive the uneven thickness. Therefore, it is bonded (fixed) to the yatoi in a distorted state. If the object to be held is adhered to the toy in a distorted state, even if highly accurate processing is performed on the object to be held, the distortion during adhesion will be restored when the object to be held is peeled off from the toy after processing. I will end up.
そこで、被保持物をヤトイに接着する際の歪みを低減するための技術も提案されている（特許文献２参照）。特許文献２に開示された技術では、ヤトイの表面に可撓性のチューブを配置し、かかるチューブの内部にエポキシ樹脂を満たした状態で被保持物を載置して、被保持物の形状に倣った形状でエポキシ樹脂を硬化させる。更に、特許文献２に開示された技術では、上述したチューブと並行して気体を通したチューブを配置し、かかるチューブの内部の気圧を適宜制御している。
Therefore, a technique for reducing distortion when adhering an object to be held to a toy has been proposed (see Patent Document 2). According to the technique disclosed in Patent Document 2, a flexible tube is arranged on the surface of the toy, and the object to be held is placed in a state in which the inside of the tube is filled with an epoxy resin to form the object to be held. The epoxy resin is hardened in a shape that follows. Furthermore, in the technique disclosed in Patent Document 2, a gas-permeable tube is arranged in parallel with the above-mentioned tube, and the atmospheric pressure inside the tube is appropriately controlled.
しかしながら、特許文献２に開示された技術では、チューブ間の保持がなされず、かかる部分で被保持物の形状が歪んでしまうため、被保持物の変形が十分に抑制されているとはいえない。更に、特許文献２に開示された技術では、チューブがヤトイに固定されていないため、被保持物の加工時に必要な保持力が不足することが容易に想定される。
However, in the technique disclosed in Patent Document 2, the tubes are not held, and the shape of the held object is distorted at such portions, so it cannot be said that the deformation of the held object is sufficiently suppressed. .. Further, in the technique disclosed in Patent Document 2, since the tube is not fixed to the toy, it is easily assumed that the holding force required when processing the held object is insufficient.
本発明は、被保持物を変形させずに保持するのに有利な保持方法を提供する。

図１は、本発明の一側面としての保持方法を説明するための図である。かかる保持方法は、ヤトイ１を用いて被保持物（被加工物）を保持する方法であって、本実施形態では、被保持物や被加工物として薄型の光学素子、具体的には、ミラー３を保持する。
FIG. 1 is a diagram for explaining a holding method according to one aspect of the present invention. This holding method is a method of holding an object to be held (object to be processed) using the toy 1, and in the present embodiment, a thin optical element as the object to be held or the object to be processed, specifically, a mirror. Holds 3.
ヤトイ１は、被保持物（被加工物）に対して高精度な加工、例えば、研磨を行う際に、被保持物を保持するための治具であって、ミラー３を保持する保持面１ａを含む。ミラー３は、本実施形態では、第１面３ａと、第１面３ａとは反対側の第２面３ｂとを含み、第１面３ａは、凸面を含む裏面を形成し、第２面３ｂは、凹面形状を有する（凹面を含む）反射面を形成する。このように、第１面３ａ及び第２面３ｂは、所謂、メニスカス形状を形成する。ミラー３は、例えば、液晶露光装置に用いられるミラーや天体望遠鏡に用いされる主鏡などを含む。
The toy 1 is a jig for holding an object to be held (high-precision machining, for example, polishing) on an object to be held (object to be processed), and is a holding surface 1a for holding a mirror 3. including. In the present embodiment, the mirror 3 includes a first surface 3a and a second surface 3b opposite to the first surface 3a, and the first surface 3a forms a back surface including a convex surface and a second surface 3b. Form a reflective surface having a concave shape (including a concave surface). Thus, the first surface 3a and the second surface 3b form a so-called meniscus shape. The mirror 3 includes, for example, a mirror used in a liquid crystal exposure apparatus and a main mirror used in an astronomical telescope.
本実施形態における保持方法は、図１に示すように、ヤトイ１とミラー３との間、詳細には、ヤトイ１の保持面１ａとミラー３の第１面３ａとの間に接着剤２を充填する。次いで、接着剤２を硬化させる前に、ヤトイ１の保持面１ａと対向するミラー３の第１面３ａとは反対側の第２面３ｂに荷重４をかける（載荷する）。この際、接着剤２からミラー３に作用する浮力と、ミラー３の重量とに基づいて、荷重４の大きさを決定し、かかる大きさでミラー３の第２面３ｂに荷重４をかける。具体的には、荷重４の大きさとミラー３の重量との和が接着剤２からミラー３に作用する浮力と等しくなるように荷重４の大きさを調整（決定）する。そして、ミラー３の第２面３ｂに荷重４をかけた状態で接着剤２を硬化させて、ヤトイ１の保持面１ａにミラー３を接着させる。
As shown in FIG. 1, the holding method according to the present embodiment uses an adhesive 2 between the touchscreen 1 and the mirror 3, more specifically, between the holding surface 1a of the touchscreen 1 and the first surface 3a of the mirror 3. Fill. Then, before the adhesive 2 is cured, a load 4 is applied (loaded) to the second surface 3b of the mirror 3 which faces the holding surface 1a of the toy 1 and is opposite to the first surface 3a. At this time, the magnitude of the load 4 is determined based on the buoyant force acting on the mirror 3 from the adhesive 2 and the weight of the mirror 3, and the load 4 is applied to the second surface 3b of the mirror 3 with such a magnitude. Specifically, the magnitude of the load 4 is adjusted (determined) so that the sum of the magnitude of the load 4 and the weight of the mirror 3 becomes equal to the buoyancy acting on the mirror 3 from the adhesive 2. Then, the adhesive 2 is cured while the load 4 is applied to the second surface 3b of the mirror 3, and the mirror 3 is adhered to the holding surface 1a of the toy 1.
本実施形態の保持方法によれば、ヤトイ１がミラー３を略無重力で保持した状態で接着剤２を硬化させることができる。これにより、ミラー３をヤトイ１に接着（固定）する際における、ミラー３の自重による変形の影響、ヤトイ１及びミラー３の形状誤差の影響、接着剤２の厚さむらの影響を抑制することができる。従って、本実施形態の保持方法は、ミラー３を変形させることなく、ヤトイ１で保持することができる。
According to the holding method of this embodiment, the adhesive 2 can be cured while the mirror 2 holds the mirror 3 with substantially zero gravity. Thereby, when the mirror 3 is adhered (fixed) to the hairtoy 1, the influence of the deformation of the mirror 3 due to its own weight, the influence of the shape error of the hairtoy 1 and the mirror 3, and the influence of the uneven thickness of the adhesive 2 are suppressed. You can Therefore, according to the holding method of the present embodiment, the mirror 3 can be held by the toy 1 without being deformed.
ここで、接着剤２は、ヤトイ１とミラー３とを結合する機能を有していればよい。接着剤２としては、例えば、石膏（硫酸カルシウム）が好適である。石膏は、硬化膨張率が低いため、接着時の変形を抑える点で有利である。更に、石膏は、入手性やコストの点でも有利である。また、接着剤２として、樹脂又は低融点金属を用いてもよい。樹脂や低融点金属は、硬化時間が短い、或いは、剥離しやすいという特徴を有しているため、リードタイムの短縮の点で有利である。
_Here, the adhesive 2 may have a function of connecting the yattoy 1 and the mirror 3. As the adhesive 2, for example, gypsum (calcium sulfate) is suitable. Gypsum is advantageous in that it suppresses deformation during bonding because it has a low curing expansion coefficient. Further, gypsum is advantageous in terms of availability and cost. Alternatively, a resin or a low melting point metal may be used as the adhesive 2. Resins and low-melting-point metals are advantageous in shortening the lead time because they have the characteristics that the curing time is short or they are easily peeled off.
荷重４は、接着剤２の領域にわたって、即ち、ミラー３の第２面３ｂのうち、ミラー３の第１面３ａと接着剤２とが接触している領域が第２面３ｂに投影された領域に均一にかけることが好ましい。本実施形態では、ミラー３の第２面上に液体を張ることで荷重４をかける。かかる液体としては、例えば、ポリタングステン酸ナトリウム水溶液が好適である。ポリタングステン酸ナトリウム水溶液は、溶解性が良好であるため、比重を高くすることが可能であり、且つ、濃度調整が容易である点で有利である。更に、ポリタングステン酸ナトリウム水溶液は、人体に無毒である点や再利用性が高い点でも有利である。
The load 4 is projected over the area of the adhesive 2, that is, in the second surface 3b of the mirror 3, the area where the first surface 3a of the mirror 3 and the adhesive 2 are in contact is projected on the second surface 3b. It is preferred that the area be evenly applied. In this embodiment, the load 4 is applied by spreading the liquid on the second surface of the mirror 3. As such a liquid, for example, a sodium polytungstate aqueous solution is suitable. Since the sodium polytungstate aqueous solution has good solubility, it is advantageous in that the specific gravity can be increased and the concentration can be easily adjusted. Further, the sodium polytungstate aqueous solution is advantageous in that it is nontoxic to the human body and has high reusability.
また、ミラー３の第２面上に、粉末、或いは、１０ｍｍ程度の小径の金属粒又は樹脂粒を配置することで荷重４をかけてもよい。金属粒又は樹脂粒は、荷重４を取り除く際に、回収が容易である点で有利である。
Further, the load 4 may be applied by disposing powder or metal particles or resin particles having a small diameter of about 10 mm on the second surface of the mirror 3. Metal particles or resin particles are advantageous in that they can be easily recovered when the load 4 is removed.
ヤトイ１の保持面１ａは、ミラー３の第１面３ａの凸面形状に対応して、凹面形状を有する（凹面を含む）。ヤトイ１の保持面１ａの凹面形状は、本実施形態では、ミラー３の第１面３ａの凸面の曲率と等しい曲率を有する。これにより、接着剤２の厚さを均一化し、接着剤２の硬化時の膨張や収縮によるミラー３の変形への影響を均一化することが可能となる。
The holding surface 1a of the yaytoy 1 has a concave shape (including a concave surface) corresponding to the convex shape of the first surface 3a of the mirror 3. In this embodiment, the concave shape of the holding surface 1a of the toy 1 has a curvature equal to the curvature of the convex surface of the first surface 3a of the mirror 3. As a result, the thickness of the adhesive 2 can be made uniform, and the influence on the deformation of the mirror 3 due to the expansion and contraction of the adhesive 2 during curing can be made uniform.
本実施形態の保持方法は、例えば、被加工物（被保持物）であるミラー３を加工する加工方法に適用される。かかる加工方法では、接着剤２を硬化させた後に、ミラー３の第２面３ｂにかけている荷重４を取り除く（除荷する）。そして、ヤトイ１に保持されたミラー３の第２面３ｂに対して、研削加工や研磨加工などの加工を行う。ミラー３の第２面３ｂを加工した後、ヤトイ１からミラー３を剥離する。例えば、ミラー３の第２面３ｂを吸着（保持）しながら、接着剤２にくさびを入れることで、ヤトイ１からミラー３を容易に剥離することができる。このような加工方法によれば、ヤトイ１からミラー３を剥離する際に接着時の変形（歪み）が復元することがないため、ミラー３を高精度に加工することができる。
The holding method of the present embodiment is applied to, for example, a processing method for processing the mirror 3 that is a workpiece (holding object). In this processing method, after the adhesive 2 is cured, the load 4 applied to the second surface 3b of the mirror 3 is removed (unloaded). Then, the second surface 3b of the mirror 3 held by the toy 1 is subjected to processing such as grinding or polishing. After the second surface 3b of the mirror 3 is processed, the mirror 3 is peeled from the toy 1. For example, by inserting (holding) the second surface 3b of the mirror 3 into the adhesive 2 with a wedge, the mirror 3 can be easily peeled from the toy 1. According to such a processing method, since the deformation (distortion) at the time of adhesion is not restored when the mirror 3 is peeled from the toy 1, the mirror 3 can be processed with high accuracy.
図２Ａ乃至図２Ｅを参照して、本実施形態の保持方法及び加工方法、即ち、ヤトイ１にミラー３を接着（固定）してミラー３を加工する手順について具体的に説明する。
With reference to FIGS. 2A to 2E, a holding method and a processing method of the present embodiment, that is, a procedure for processing the mirror 3 by adhering (fixing) the mirror 3 to the yattoy 1 will be specifically described.
まず、図２Ａに示すように、作業定盤（不図示）の上にヤトイ１を配置する。次いで、図２Ｂに示すように、ヤトイ１の保持面１ａに接着剤２を供給（塗布）する。次に、図２Ｃに示すように、ヤトイ１の保持面１ａに供給された接着剤２の上に、ミラー運搬工具（不図示）を用いてミラー３を載置する。このように、ヤトイ１の保持面１の上に、接着剤２を介して、ミラー３を配置する（第１工程）。
First, as shown in FIG. 2A, the yatoy 1 is placed on a work surface plate (not shown). Next, as shown in FIG. 2B, the adhesive 2 is supplied (applied) to the holding surface 1 a of the toy 1. Next, as shown in FIG. 2C, the mirror 3 is placed on the adhesive 2 supplied to the holding surface 1a of the eye toy 1 using a mirror carrying tool (not shown). In this way, the mirror 3 is arranged on the holding surface 1 of the toy 1 via the adhesive 2 (first step).
次いで、図２Ｄに示すように、接着剤２を硬化させる前に、荷重投入工具（不図示）を用いて、ヤトイ１の保持面１ａと対向するミラー３の第１面３ａとは反対側の第２面３ｂに荷重４をかける（第２工程）。そして、ミラー３の第２面３ｂに荷重４をかけた状態を維持しながら接着剤２が硬化するまで待機する。このように、ミラー３の第２面３ｂに荷重４をかけた状態で接着剤２を硬化させてヤトイ１の保持面１ａにミラー３を接着させる（第３工程）。
Then, as shown in FIG. 2D, before the adhesive 2 is cured, a load insertion tool (not shown) is used to remove the adhesive on the opposite side of the holding surface 1a of the toy 1 from the first surface 3a of the mirror 3. A load 4 is applied to the second surface 3b (second step). Then, while maintaining the state in which the load 4 is applied to the second surface 3b of the mirror 3, it waits until the adhesive 2 is cured. In this way, the adhesive 2 is cured while the load 4 is applied to the second surface 3b of the mirror 3 to bond the mirror 3 to the holding surface 1a of the touch panel 1 (third step).
次に、図２Ｅに示すように、接着剤２を硬化させた後に、荷重排出工具（不図示）を用いて、ミラー３の第２面３ｂにかけている荷重４を取り除く（第４工程）。そして、ヤトイ１に保持（固定）されたミラー３の第２面３ｂを加工（切削加工や研磨加工など）する（第５工程）。
Next, as shown in FIG. 2E, after the adhesive 2 is cured, the load 4 applied to the second surface 3b of the mirror 3 is removed using a load discharging tool (not shown) (fourth step). Then, the second surface 3b of the mirror 3 held (fixed) by the toy 1 is processed (cutting, polishing, etc.) (fifth step).
このような手順でミラー３を保持及び加工することで、上述したように、ミラー３を変形させることなく保持することができ、且つ、ミラー３を高精度に加工することができる。
By holding and processing the mirror 3 in such a procedure, as described above, the mirror 3 can be held without being deformed, and the mirror 3 can be processed with high accuracy.
図３を参照して、接着剤２を硬化させる前にミラー３の第２面３ｂにかける荷重４の大きさを決定する方法について説明する。ミラー３の第１面３ａの側のある点３０において、接着剤２からミラー３にかかる圧力（静水圧）Ｐは、接着剤２の密度ρ２、重力加速度ｇ、点３０から接着剤２の液面までの距離ｈ２を用いて、以下の式（１）で表すことができる。
A method for determining the magnitude of the load 4 applied to the second surface 3b of the mirror 3 before the adhesive 2 is cured will be described with reference to FIG. At a certain point 30 on the side of the first surface 3 a of the mirror 3, the pressure (hydrostatic pressure) P applied from the adhesive 2 to the mirror 3 is the density ρ 2 of the adhesive 2 , the gravitational acceleration g, and the adhesive 30 from the point 30. It can be expressed by the following equation (1) using the distance h 2 to the liquid surface.
Ｐ＝ρ２×ｇ×ｈ２ ・・・（１）
更に、ミラー３の第１面３ａの全面が接着剤２から受ける浮力Ｆは、ミラー３の第１面３ａの各点の圧力（静水圧）Ｐの総和であるため、以下の式（２）で表すことができる。 P = ρ 2 × g × h 2 (1)
Further, the buoyancy F received by the adhesive 2 on the entirefirst surface 3a of the mirror 3 is the sum of the pressures (hydrostatic pressures) P at the points on the first surface 3a of the mirror 3, and therefore the following formula (2) Can be expressed as
更に、ミラー３の第１面３ａの全面が接着剤２から受ける浮力Ｆは、ミラー３の第１面３ａの各点の圧力（静水圧）Ｐの総和であるため、以下の式（２）で表すことができる。 P = ρ 2 × g × h 2 (1)
Further, the buoyancy F received by the adhesive 2 on the entire
Ｆ＝ΣＰ ・・・（２）
式（２）に示す浮力Ｆが、ミラー３の重量Ｍ３ｇと、荷重４の大きさＭ４ｇとの和と等しくなるように、具体的には、以下の式（３）を満たすように、荷重４の大きさＭ４ｇを決定する。 F = ΣP (2)
The buoyancy F shown in Expression (2) is equal to the sum of the weight M 3g of the mirror 3 and the magnitude M 4g of the load 4, specifically, to satisfy the following Expression (3), The magnitude M 4g of load 4 is determined.
式（２）に示す浮力Ｆが、ミラー３の重量Ｍ３ｇと、荷重４の大きさＭ４ｇとの和と等しくなるように、具体的には、以下の式（３）を満たすように、荷重４の大きさＭ４ｇを決定する。 F = ΣP (2)
The buoyancy F shown in Expression (2) is equal to the sum of the weight M 3g of the mirror 3 and the magnitude M 4g of the load 4, specifically, to satisfy the following Expression (3), The magnitude M 4g of load 4 is determined.
Ｆ＝Ｍ３ｇ＋Ｍ４ｇ ・・・（３）
更に、ミラー３の第１面３ａの側の微小面積をｄｓとすると、微小面積ｄｓが接着剤２から受ける圧力（静水圧）は、微小面積ｄｓを鉛直方向に延ばすことで形成される円筒５０に含まれるミラー３と荷重４の重量との和との間に釣り合いの式が成り立つ。ミラー３の密度をρ３、円筒５０に含まれるミラー３の鉛直方向の長さをｈ３とし、荷重４の密度をρ４、円筒に含まれる荷重４の鉛直方向の長さをｈ４とすると、釣り合いの式は、以下の式（４）で表される。 F = M 3g + M 4g (3)
Furthermore, assuming that the minute area on thefirst surface 3a side of the mirror 3 is ds, the pressure (hydrostatic pressure) that the minute area ds receives from the adhesive 2 is a cylinder 50 formed by extending the minute area ds in the vertical direction. A balance equation is established between the sum of the weight of the mirror 3 and the weight of the load 4 included in. The density of the mirror 3 is ρ 3 , the vertical length of the mirror 3 included in the cylinder 50 is h 3 , the density of the load 4 is ρ 4 , and the vertical length of the load 4 included in the cylinder is h 4 . Then, the balance equation is expressed by the following equation (4).
更に、ミラー３の第１面３ａの側の微小面積をｄｓとすると、微小面積ｄｓが接着剤２から受ける圧力（静水圧）は、微小面積ｄｓを鉛直方向に延ばすことで形成される円筒５０に含まれるミラー３と荷重４の重量との和との間に釣り合いの式が成り立つ。ミラー３の密度をρ３、円筒５０に含まれるミラー３の鉛直方向の長さをｈ３とし、荷重４の密度をρ４、円筒に含まれる荷重４の鉛直方向の長さをｈ４とすると、釣り合いの式は、以下の式（４）で表される。 F = M 3g + M 4g (3)
Furthermore, assuming that the minute area on the
Ｐ×ｄｓ＝｛（ρ３×ｇ×ｈ３）＋（ρ４×ｇ×ｈ４）｝×ｄｓ ・・・（４）
式（４）がミラー３の第１面３ａの側の全面で成り立てば、無重力状態で変形を抑えたミラー３の保持を実現することができる。式（４）の両辺をｄｓで除し、式（１）を代入すると、以下の式（５）が得られ、これが無重力状態で変形を抑えたミラー３の保持を実現する条件となる。 P × ds = {(ρ 3 × g × h 3 ) + (ρ 4 × g × h 4 )} × ds (4)
If the formula (4) is satisfied on the entire surface of themirror 3 on the first surface 3a side, it is possible to realize the holding of the mirror 3 in which deformation is suppressed in a weightless state. By dividing both sides of the equation (4) by ds and substituting the equation (1), the following equation (5) is obtained, which is a condition for realizing the holding of the mirror 3 in which deformation is suppressed in a weightless state.
式（４）がミラー３の第１面３ａの側の全面で成り立てば、無重力状態で変形を抑えたミラー３の保持を実現することができる。式（４）の両辺をｄｓで除し、式（１）を代入すると、以下の式（５）が得られ、これが無重力状態で変形を抑えたミラー３の保持を実現する条件となる。 P × ds = {(ρ 3 × g × h 3 ) + (ρ 4 × g × h 4 )} × ds (4)
If the formula (4) is satisfied on the entire surface of the
ρ２×ｇ×ｈ２＝（ρ３×ｇ×ｈ３）＋（ρ４×ｇ×ｈ４） ・・・（５）
