【発明の属する技術分野】
本発明は、AlTiC基板、セラミック基板、ガラス基板、GaAs基板、金属板等の平板状ワ−クを表裏面の平行出しを良好に精密に平面研削する方法および、その研削に用いるワ−ク治具に関する。
【0002】
【従来の技術】
平板状ワ−ク表面を精密にレベル出しする平面研削方法が行われている。
例えば、左右方向に沿って摺動する支持台の上に載置される平行バネと、平行バネ上に載せられた作業テ−ブル上に固定されたワ−クを平面研削するに、レベルセンサで支持台の左右方向移動に伴う摺動面の変位誤差を検出し、数ナノメ−トル以下に平行バネを介してワ−クの表面精度を補正する研削装置が提案されている(例えば特許文献1参照)。
また、平面研削装置の磁気テ−ブル上に固定されるとともに、固定側バイスとこの固定側バイスに対して接近離反自在の可動側バイスによりワ−クをクランプする治具も提案されている(例えば特許文献2参照)。

【発明が解決しようとする課題】
前記特許文献1に記載の平面研削装置でワ−ク表裏面を研削して平行レベルの高い加工ワ−クを得るには、ワ−クが直接、作業テ−ブル上に置かれるため、ワ−ク片面研削後に作業テ−ブル上に付着した研削屑を除去し、ついでワ−クを逆向きにして作業テ−ブル上に置き、ワ−クの多面を研削する必要があり、この作業テ−ブルの清掃とワ−クの位置合わせの段取りに十数分要する欠点がある。
【0005】
前記特許文献2に記載の固定側バイスと可動側バイスを備える平面研削装置では、ワ−クが作業台テ−ブル表面から浮いた状態で研削されるため、作業テ−ブル上の研削屑の汚れは左程気にする必要はないが、ワ−クを固定側バイスと可動側バイス間に浮かして固定する段取りを平面研削装置内で行う必要があり、10分前後、その段取りに要する。また、ワ−クの固定がワ−ク左右側面の2方向であり、ワ−ク前後が固定されていないので研削装置の振動により加工精度が損なわれ易い。
【0006】
本発明の第1の目的は、ワ−クを作業テ−ブルに載せる段取り時間が数分で可能で、ワ−ク前後左右側面の4面でワ−クを固定できるワ−ク治具の提供にある。本発明の他の目的は、このワ−ク治具を用い、平板状ワ−クの表裏面平行出しを良好に行うことができる平面研削方法を提供するものである。
【0007】
【課題を解決するための手段】
請求項1に記載の発明は、一対の高さ方向位置合わせコラムを上下方向に設けるとともに、側面より内側に向けて位置調整微動抑えネジを複数設けた前枠と後枠、前記前枠と後枠の間にワ−ク左端を圧押しする左圧押し枠とワ−ク右端を圧押しする右圧押し枠であってこれら圧押し枠の高さは前記前枠および後枠の高さよりは低い左圧押し枠と右圧押し枠、左圧押し枠と右圧押し枠を前記前枠および後枠に固定する固定具とを備えるワ−ク治具であって、平板状ワ−クはその前後側面を前枠および後枠に備えられた位置調整微動抑えネジで圧押しされ、左右方向を左圧押し枠と右圧押し枠で圧押しされて固定され、このワ−ク治具が作業テ−ブル上に載置されたときは平板状ワ−クの下面は作業テ−ブル上面より離間して置かれることを特徴とするワ−ク治具を提供するものである。
【0008】
予めワ−クを固定したワ−ク治具を複数用意しておくことにより、先のワ−クの表裏面研削後に新たなワ−ク治具を平面研削装置の作業テ−ブル上で位置合わせすることで従来十数分要していた段取りが数分で行うことができ、表裏面の研削を考慮すると一ワ−クの研削につき、約20分、段取り時間を短縮できる。
【0009】
請求項2に記載の発明は、前記ワ−ク治具において、平板状ワ−ク側面と当接する押す左圧押し枠側面と右圧押し枠側面には緩衝材が設けられていることを特徴とする。
【0010】
ゴム、エラストマ−、発泡シ−ト等の緩衝材が平板状ワ−クと圧押し枠間に存在することにより、平板状ワ−クに懸かっている抗張力が緩衝材に吸収され、平板状ワ−クや圧押し枠が反りにくくなっている。
【0011】
請求項3に記載の発明は、前記ワ−ク治具において、前枠および後枠には、ワ−ク治具搬送時のア−ム位置決めピンがそれぞれ左右に一対設けられていることを特徴とする。
【0012】
ワ−ク治具が図示されていないストッカ−からロ−ダにより平面研削装置の作業台上に搬送されて来る際のロ−ダア−ムがワ−ク治具を把持するピンを設けたことにより、機械搬入を可能とした。
【0013】
請求項4に記載の発明は、前記ワ−ク治具を平面研削装置の作業テ−ブル上の所望位置に載置し、ついで作業テ−ブルの送りによるワ−クの移動と回転する砥石車との相対的な移動により平板状ワ−クの上面を平面研削した後、ワ−ク治具を逆向きに作業テ−ブル上の所望位置に載置し、次いで、作業テ−ブルの送りによるワ−クの移動と回転する砥石車との相対的な移動により平板状ワ−クの上面を平面研削することを特徴とする、ワ−ク表裏面の研削方法を提供するものである。
【0014】
ワ−クが作業テ−ブルより浮いて平面研作加工されるため、作業テ−ブル上に付着した研削屑の存在の影響を受けずに研削でき、ワ−クの平行度を出すための作業テ−ブル清掃時間が短縮できる。また、ワ−クの四端が固定されて研削されるので平面研削装置の振動によるワ−クの加工精度が影響を受けることが減少される。
【0015】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for satisfactorily and precisely grinding a flat work such as an AlTiC substrate, a ceramic substrate, a glass substrate, a GaAs substrate, and a metal plate so that the front and back surfaces are parallelized, and a work jig used for the grinding. About the tool.
[0002]
[Prior art]
A surface grinding method for precisely leveling a flat work surface has been used.
For example, a level sensor is used for surface grinding of a parallel spring mounted on a support table sliding along the left and right direction and a work fixed on a work table mounted on the parallel spring. There has been proposed a grinding device that detects a displacement error of a sliding surface due to a lateral movement of a support base and corrects a surface accuracy of a work through a parallel spring to several nanometers or less (for example, Patent Document 1). 1).
Further, a jig which is fixed on a magnetic table of a surface grinding device and clamps a workpiece by a fixed vice and a movable vise which can freely move toward and away from the fixed vise has been proposed. For example, see Patent Document 2).
[0003]
[Patent Document 1]
JP-A-6-91458 (see page 3-5 and FIG. 1)
[Patent Document 2]
JP-A-8-309633 (see page 3-5 and FIG. 1)
[0004]
[Problems to be solved by the invention]
In order to grind the front and back surfaces of the work with the surface grinding device described in Patent Document 1 and obtain a processed work having a high parallel level, the work is directly placed on the work table. -After grinding one side of the work, it is necessary to remove grinding debris adhering to the work table, and then place the work on the work table with the work turned upside down to grind the work surface. There is a disadvantage that it takes more than ten minutes to clean up the table and set up the work alignment.
[0005]
In the surface grinding device having the fixed-side vice and the movable-side vise described in Patent Literature 2, since the work is ground in a state of being floated from the surface of the worktable, the grinding dust on the worktable is reduced. It is not necessary to worry about dirt, but it is necessary to set up the work by floating it between the fixed-side vice and the movable-side vise in a surface grinding device, which takes about 10 minutes. Further, the work is fixed in two directions on the left and right side surfaces of the work, and the front and rear of the work are not fixed. Therefore, the machining accuracy is easily deteriorated by the vibration of the grinding device.
[0006]
A first object of the present invention is to provide a work jig which can set up a work on a work table in a few minutes and can fix the work on four sides of the front, rear, left and right side surfaces. On offer. Another object of the present invention is to provide a surface grinding method capable of satisfactorily aligning the front and back surfaces of a flat workpiece using the work jig.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, a pair of height-direction alignment columns are provided in the vertical direction, and a plurality of position adjustment fine movement suppressing screws are provided inwardly from the side surfaces. A left pressing frame for pressing the left end of the work between the frames and a right pressing frame for pressing the right end of the work, wherein the height of the pressing frames is higher than the height of the front frame and the rear frame. A work jig provided with a lower left press frame and a right press frame, and a fixture for fixing the left press frame and the right press frame to the front frame and the rear frame. The front and rear sides are pressed by the position adjustment fine movement holding screws provided on the front frame and the rear frame, and are pressed and fixed in the left and right directions by the left and right pressing frames. When placed on a work table, the lower surface of the flat work is spaced apart from the upper surface of the work table. Suruwa - there is provided a click jig.
[0008]
By preparing a plurality of work jigs to which the work is fixed in advance, a new work jig can be positioned on the work table of the surface grinding device after the front and back surfaces of the previous work are ground. The alignment can be done in a few minutes, which takes about ten minutes conventionally, and the grinding time of one work can be reduced by about 20 minutes per grinding in consideration of the grinding of the front and back surfaces.
[0009]
The invention according to claim 2 is characterized in that, in the work jig, a cushioning material is provided on a side surface of the left pressing frame and a side surface of the right pressing frame that come into contact with the side surface of the flat workpiece. And
[0010]
Since the cushioning material such as rubber, elastomer, foam sheet, etc. exists between the flat work and the pressing frame, the tensile strength suspended on the flat work is absorbed by the cushion material, and the flat work is absorbed. -The press and press frames are less likely to warp.
[0011]
According to a third aspect of the present invention, in the work jig, the front frame and the rear frame are provided with a pair of arm positioning pins on the left and right sides when the work jig is conveyed. And
[0012]
The load arm is provided with a pin for gripping the work jig when the work jig is conveyed from a stocker (not shown) to a work table of a surface grinding device by a loader. With this, the machine can be brought in.
[0013]
According to a fourth aspect of the present invention, the work jig is placed at a desired position on a work table of a surface grinding apparatus, and then the work wheel is moved and rotated by feeding the work table. After the upper surface of the plate-shaped work is ground by relative movement with the car, the work jig is placed in a desired position on the work table in the opposite direction, and then the work jig is placed on the work table. An object of the present invention is to provide a method of grinding the front and back surfaces of a work, wherein the top surface of a flat work is ground by moving the work by feeding and moving relative to a rotating grinding wheel. .
[0014]
Since the work is lifted from the work table and planarly machined, it can be ground without being affected by the presence of grinding debris attached to the work table, and work for achieving parallelism of the work Table cleaning time can be reduced. Further, since the four ends of the work are fixed and ground, the influence of the vibration of the surface grinding device on the processing accuracy of the work is reduced.
[0015]
