Description
【発明の詳細な説明】 （発明の利用分野） 本発明は板状試料の位置決め機構に関する。[Detailed description of the invention] (Field of application of the invention) The present invention relates to a positioning mechanism for a plate-shaped sample.
（発明の背景）
ペレツトボンデイング装置、ワイヤボンデイン
グ装置においては、ボンデイング前に板状試料
（以下、単に試料という）を位置決めすることが
行われている。(Background of the Invention) In pellet bonding devices and wire bonding devices, a plate-shaped sample (hereinafter simply referred to as a sample) is positioned before bonding.
従来の試料の位置決め機構は、第１図に示すよ
うに相対向して配設された２個のＶ爪１，２を矢
印方向に開閉させ、試料台３に載置された四角形
状の試料４の外形をＶ爪１，２によつて押して位
置決めしている。 As shown in FIG. 1, the conventional sample positioning mechanism opens and closes two V-claws 1 and 2 facing each other in the direction of the arrows, thereby positioning a rectangular sample placed on a sample stage 3. The outer shape of 4 is pressed and positioned by V claws 1 and 2.
しかしながら、かかる機構は、試料４の角４ａ
がＶ爪１，２の内面を滑ることで位置決めされる
ので、Ｖ爪１，２は硬い材料で表面が滑らかに加
工されているが、試料４は角の状態によつて滑り
にくいものもあり、かかる試料４は破損、傷等が
発生すると共に、位置決め精度が悪い。また試料
４が当るＶ爪１，２の部分は局部的な一定の範囲
に限られるので、摩耗が著しく、寿命が短く、長
期間の使用ができない。特に試料４がセラミツク
の場合はこの傾向が著しい。 However, such a mechanism
is positioned by sliding on the inner surface of V-claws 1 and 2, so V-claws 1 and 2 are made of hard material and have smooth surfaces, but sample 4 may be difficult to slip due to the condition of the corners. Such a sample 4 may be damaged, scratched, etc., and its positioning accuracy may be poor. Further, since the portions of the V claws 1 and 2 that the sample 4 comes into contact with are limited to a certain local area, they are subject to significant wear and have a short lifespan, making it impossible to use them for a long period of time. This tendency is particularly remarkable when Sample 4 is made of ceramic.
（発明の目的）
本発明の目的は、試料をスムーズに精度良く位
置決めできると共に、機構の長寿命化が図れる試
料の位置決め機構を提供することにある。(Objective of the Invention) An object of the present invention is to provide a sample positioning mechanism that can position a sample smoothly and accurately, and can extend the life of the mechanism.
（発明の実施例）
以下、本発明の一実施例を第２図により説明す
る。相対向して配設された２個の位置決め部材１
０，２０は、互いに接近及び離反する方向に移動
するローラ支持部材１１，２１を有し、このロー
ラ支持部材１１，２１にそれぞれローラ１２，１
３及び２２，２３が回転自在に設けられている。(Embodiment of the Invention) An embodiment of the present invention will be described below with reference to FIG. Two positioning members 1 arranged opposite to each other
0 and 20 have roller support members 11 and 21 that move toward and away from each other, and rollers 12 and 1 are attached to these roller support members 11 and 21, respectively.
3, 22, and 23 are rotatably provided.
前記一方のローラ１２，１３は、その回転中心
間距離l1が試料４の幅Ｈより大きくなるように配
設され、試料４の角４ａに当接するようになつて
いる。他方のローラ２２，２３は、その回転中心
間距離l2が試料４の幅Ｈより小さくなるように配
設され、試料４の側面に当接するようになつてい
る。 One of the rollers 12 and 13 is disposed such that the distance l 1 between their centers of rotation is greater than the width H of the sample 4, and is adapted to abut against a corner 4a of the sample 4. The other rollers 22 and 23 are arranged so that the distance l 2 between their rotation centers is smaller than the width H of the sample 4, and are in contact with the side surface of the sample 4.
次に作用を第３図によつて説明する。同図ａに
示すように位置決め部材１０，２０が開いた状態

り、まず同図ｂに示すようにローラ２２が試料４
の側面の一端側に当接し、試例４はローラ２２に
よつて他端側がローラ２３に当接するまで動かさ
れ、傾きが修正される。この場合、試料４の動き
によつてローラ２２は回転させられる。 Next, the operation will be explained with reference to FIG. When the sample 4 is placed on the sample stage (not shown) with the positioning members 10, 20 open as shown in FIG. etc., in the direction of approaching each other. As a result, the roller 22 first moves the sample 4 as shown in FIG.
sample 4 is moved by the roller 22 until the other end comes into contact with the roller 23, and the inclination is corrected. In this case, the movement of the sample 4 causes the roller 22 to rotate.
続いて、同図ｃに示すようにローラ１３に試料
４の角４ａが当接し、ローラ１２，１３及び２
２，２３の内側へ寄せる力により試料４はローラ
１２の方向へ動かされる。これによりローラ１３

位置決めされる。位置決めが完了すると、同図ｅ
に示すように位置決め部材１０，２０は元の位置
に戻る。これにより、一連の位置決め動作が完了
する。 Subsequently, the corner 4a of the sample 4 comes into contact with the roller 13, as shown in FIG.
The sample 4 is moved in the direction of the roller 12 by the inward force of the rollers 2 and 23. As a result, roller 13
is rotated in the direction of the arrow. Also, due to the movement of the sample 4, the rollers 22 and 23
can also be rotated in the direction of the arrow. Then, the sample 4 is positioned against the four rollers 12, 13 and 22, 23. When positioning is complete,
The positioning members 10 and 20 return to their original positions as shown in FIG. This completes a series of positioning operations.
このように、試料４の位置決めの時は、ローラ
１２，１３，２２，２３が回転するので、試料の
移動はスムーズに行われる。 In this way, when positioning the sample 4, the rollers 12, 13, 22, and 23 rotate, so that the sample can be moved smoothly.
なお、第２図においては、ローラ１２，１３の
回転中心を結ぶ線Ａと、ローラ１２，１３の回転
中心と試料４の角４ａを結ぶ線Ｂとのなす角度θ

30度にすると、ローラ１２，１３間の中心距離l1
は図示の場合より大きくなるので、試料４が中央
に一層寄り易くなる。しかしながら、角度θが大
きすぎ又は小さすぎると、ローラ１２，１３が回
転しにくくなるので、角度θは30〜45度の範囲が
好ましいが、20〜55度の範囲でも実用上支差えな
い。 In addition, in FIG. 2, the angle θ between the line A connecting the rotation centers of the rollers 12 and 13 and the line B connecting the rotation centers of the rollers 12 and 13 and the corner 4a of the sample 4 is
is 45 degrees, but this angle θ can be changed to, for example,
If the angle is 30 degrees, the center distance between rollers 12 and 13 is l 1
is larger than in the illustrated case, so the sample 4 is more likely to come to the center. However, if the angle θ is too large or too small, the rollers 12 and 13 will become difficult to rotate. Therefore, the angle θ is preferably in the range of 30 to 45 degrees, but may be in the range of 20 to 55 degrees.

る。 4 and 5 show second and third embodiments of the present invention. In the embodiment described above, both the positioning members 10 and 20 have rollers 12, 13 and 22, 23, but in the embodiment shown in FIG. It is formed flat. In the embodiment shown in FIG. 5, the contact area of the abutting surface of the positioning member 40 is reduced, and the sliding is improved compared to the case shown in FIG. 4. Since the positioning members 30 and 40 abut against the side surface of the sample 4, their influence on the sample 4 is smaller than that of the positioning member 10 that abuts against the corner 4a of the sample 4. Therefore, as shown in FIGS. 4 and 5, a more significant effect can be obtained than in the past even without the use of rollers.
なお、上記実施例においては、２個の位置決め

動するものにも適用できることはいうまでもな
い。 In the above embodiment, the case where the two positioning members 10 and 20 (or 30, 40) move together has been described, but it goes without saying that the present invention can also be applied to a case where either one of them moves.
