品の中心位置を部品搭載ヘツドの中心線上に正確
に位置決めしなければならない。 In electronic component mounting equipment, IC chips and other chip-type electronic components fed by a component supply device are picked up by a component mounting head and mounted on a predetermined position on a printed circuit board, but the accuracy of the mounting position is critical. In order to improve the performance, it is necessary to accurately position the center of the fed electronic component on the center line of the component mounting head.
第７図は従来の電子部品の位置決め装置の一例

90度間隔で枢着され、ばね５によつて内方に付勢
された４本の把持部材６の突起６ａがそれぞれ係
合して把持部材６を開放状態に保つている。 FIG. 7 shows an example of a conventional electronic component positioning device.A conical three-dimensional cam 2 is attached to the outer periphery of the component mounting head 1 so as to be slidable along the axis. As shown in the figure, it is pressed downward against the spring 3 by a cylinder or solenoid. A shaft 4 is attached to the cam surface 2a of the three-dimensional cam 2.
The protrusions 6a of the four gripping members 6, which are pivoted at 90 degree intervals and urged inwardly by the springs 5, engage with each other to keep the gripping members 6 open.
この状態から立体カム２を下方に押圧している
付勢力を解除すると、立体カム２はばね３により
上昇して把持部材６がそれぞれ内方に回動し、そ
の爪部６ｂが同図ｂに示すように電子部品Ｐの４
辺を挟持してその中心位置を部品搭載ヘツド１の
中心線に一致させて位置決めを行う。 When the urging force pressing the three-dimensional cam 2 downward is released from this state, the three-dimensional cam 2 rises due to the spring 3, and the gripping members 6 rotate inward, so that the claws 6b of the three-dimensional cam 2 move toward the position b in the figure. As shown, electronic component P-4
Positioning is performed by holding the sides and aligning the center position with the center line of the component mounting head 1.
しかしながら、このような従来の電子部品の位
置決め装置にあつては、把持部材６の回動時の摩
擦力の差やばね５が各把持部材６に及ぼす付勢力
の差等に起因して相対向する把持部材６の回転角
が変化し、第７図ｂに仮想線で示すように電子部
品Ｐの中心位置が部品搭載ヘツド１の中心線から
ずれる恐れがある。 However, in such a conventional electronic component positioning device, due to differences in frictional force when the gripping members 6 rotate, differences in urging force exerted by the springs 5 on each gripping member 6, etc. The rotation angle of the gripping member 6 may change, and the center position of the electronic component P may shift from the center line of the component mounting head 1, as shown by the imaginary line in FIG. 7b.
また、一旦位置決めされても接触等により容易
にその位置がずれるきらいもあり、位置決め精度
が低いという問題がある。 Furthermore, even once positioned, the position tends to shift easily due to contact or the like, resulting in a problem of low positioning accuracy.
さらに、把持部材６の爪部６ｂが軸４を中心と
する円弧上を移動するので、電子部品の大きさに
よつては爪部６ｂの高さの変化により電子部品の
４辺に係合し得ない場合が生じ、位置決めし得る
電子部品の大きさの範囲が狭いという問題もあ
る。 Furthermore, since the claw portion 6b of the gripping member 6 moves on an arc centered on the shaft 4, depending on the size of the electronic component, the claw portion 6b may engage the four sides of the electronic component due to a change in height. There are also cases where it is not possible to obtain the desired position, and there is also the problem that the range of sizes of electronic components that can be positioned is narrow.
この発明は、このような従来の問題点を解決し
得る電子部品の位置決め装置を提供することを目
的とする。 An object of the present invention is to provide an electronic component positioning device that can solve these conventional problems.
そのため、この発明による電子部品の位置決め
装置は、部品搭載ヘツドの中心線に直交する平面

に装着され各把持部材に連係して相対向する把持
部材を互いに部品搭載ヘツドの中心線から等距離
に保つ第１、第２の規制部材とを設けたものであ
る。 Therefore, the electronic component positioning device according to the present invention has two pairs of gripping members that can be displaced perpendicularly to each other in a plane perpendicular to the center line of the component mounting head, and two pairs of gripping members that are opposed to each other and are attached in a direction approaching each other. A biasing means for biasing the parts, and a gripping member which is mounted so as to be independently displaceable along a main axis coaxial with the centerline of the component mounting head and which are opposed to each other in conjunction with each gripping member, are moved from each other from the centerline of the component mounting head. First and second regulating members are provided to maintain the same distance.
上記のように構成することにより、第１、第２

近接する方向に変位させて電子部品の４辺を挟持
させれば、その中心位置を部品搭載ヘツドの中心
線に一致させることができる。 By configuring as above, the first and second
The regulating members are displaced, and from the state where the two pairs of grasping members are separated from each other by resisting the biasing force, these regulating members are displaced in the opposite direction, and the two pairs of grasping members are separated from each other. If the four sides of the electronic component are pinched by displacing them in the direction of approaching each other by the biasing force, the center position can be aligned with the center line of the component mounting head.
この時、第１、第２の規制部材は、相対向する
把持部材を部品搭載ヘツドの中心線から等距離に
保つているので、電子部品の中心位置が部品搭載
ヘツドの中心位置からずれる恐れは皆無である。 At this time, since the first and second regulating members keep the opposing gripping members at the same distance from the center line of the component mounting head, there is no possibility that the center position of the electronic component will shift from the center position of the component mounting head. There are none.
そして、相対向する２対の把持部材を、部品搭

コンパクトにまとめることができると共に、位置
決め精度を著しく向上させることができる。 Since the two pairs of opposing gripping members are linked to the first and second regulating members that are independently movable along the main axis coaxial with the center line of the component mounting head, the configuration is improved. This makes it easy to make the device compact, and the positioning accuracy can be significantly improved.
また、２対の把持部材はいずれも同一平面内を
変位するのでいかなる大きさの電子部品をも確実
に把持することができ、位置決めし得る電子部品
の範囲が大幅に拡大される。 Furthermore, since both of the two pairs of gripping members are displaced within the same plane, electronic components of any size can be reliably gripped, and the range of electronic components that can be positioned is greatly expanded.
