Description

本発明は、ボールを必要とする平面状の部材上にボールを供給するためのボール供給カートリッジに関するものである。   The present invention relates to a ball supply cartridge for supplying a ball onto a planar member requiring the ball.

ボールを必要とする平面状の部材上にボールを供給するための手段として、従来図１１に示す如き樋状のホッパが用いられている。該ホッパ１００は、底部に供給口１０１を有し、水平方向に移動しながら内部に投入されたボール１０２、１０２、１０２・・・、例えば金属粒子を該供給口１０１から流出させて平面上の部材１０３上に供給するものである。   Conventionally, a bowl-shaped hopper as shown in FIG. 11 is used as means for supplying a ball onto a planar member requiring the ball. The hopper 100 has a supply port 101 at the bottom, and balls 102, 102, 102... It is supplied on the member 103.

しかし、斯かる従来のボール供給手段では、ホッパ１００内に投入したボール１０２、１０２、１０２・・・の残量が分からず、供給途中でボールがなくなり、一旦作業を中断して補充しなければならない場合もしばしばであった。また、特にボール１０２が金属粒子であって且つホッパ１００も金属製である場合には、ボール１０２とホッパ１００との接触によって強い静電気が起こり、ホッパ１００の供給口１０１からスムーズに流出しないこともある。また、このように静電気が起こることにより、例えば半導体ウエハ、、配線基板等における端子となる電極部にはんだバンプを形成するための装置に用い、該電極部にはんだボールを供給して載せるためのホッパとして用いる場合において、はんだボールがマスクの貫通孔の内面に静電気によって吸着され、貫通孔を通過して電極部まで落ち込まないことも起こり得る。   However, in such a conventional ball supply means, the remaining amount of the balls 102, 102, 102,... Thrown into the hopper 100 is not known, the balls disappear during the supply, and the operation must be interrupted and replenished. Often it was not possible. Further, particularly when the ball 102 is made of metal particles and the hopper 100 is also made of metal, strong static electricity is generated by the contact between the ball 102 and the hopper 100, and the hopper 100 may not flow out smoothly from the supply port 101. is there. In addition, due to the occurrence of static electricity in this way, for example, it is used in an apparatus for forming solder bumps on electrode portions that become terminals in semiconductor wafers, wiring boards, etc., and for supplying and placing solder balls on the electrode portions When used as a hopper, the solder balls may be attracted to the inner surface of the through hole of the mask by static electricity and may not pass through the through hole and fall into the electrode part.

本発明は上記の点に鑑みなされたものであって、内部に充填されたボールの残量の把握が容易であると共に静電気の発生を極力抑制したボール供給カートリッジを提供せんとするものである。   The present invention has been made in view of the above points, and it is an object of the present invention to provide a ball supply cartridge that can easily grasp the remaining amount of balls filled therein and suppress the generation of static electricity as much as possible.

而して、本発明の要旨とするところは、底部に供給口を設けた樋状のホッパの直上に配設し、内部に充填したボールを落としながら該樋状のホッパに沿って移動するボール供給カートリッジであって、ガラスにより所要箇所に充填口を設けた口部が窄まるガラス瓶形の形態に成形してなるボール供給カートリッジにある。   Thus, the gist of the present invention is that a ball which is disposed directly above a bowl-shaped hopper having a supply port at the bottom and moves along the bowl-shaped hopper while dropping a ball filled inside. The supply cartridge is a ball supply cartridge which is formed into a glass bottle shape in which a mouth portion provided with a filling port at a required portion is made of glass.

また、上記構成において、ガラスとして透明ガラスを用いれば、残量が視認でき、残量の把握がより一層容易且つ確実となるものである。   In the above configuration, if transparent glass is used as the glass, the remaining amount can be visually recognized, and the grasp of the remaining amount can be more easily and reliably realized.

本発明は上記の如き構成であり、カートリッジであるから、一定量宛充填すれば、一つの被供給体への使用量を使用回数で乗ずることにより容易に残量が分かる、つまり交換時期を把握することができるものである。したがって、従来の如く途中でボールがなくなって作業を中断する無駄を省くことができるものである。そしてまた、ボールを密閉された中に保存するから、埃の付着を防ぐことができ、またカートリッジであるから新しいものと交換が迅速に行えるものである。また、ガラス製であることから静電気が起こりにくいものである。また、透明ガラスであれば残量が視認でき、残量の把握がより一層容易且つ確実になるものである。   Since the present invention is configured as described above and is a cartridge, if a fixed amount is filled, the remaining amount can be easily found by multiplying the amount of use to one supplied object by the number of times of use, that is, the replacement time Is something that can be done. Therefore, it is possible to eliminate the waste of interrupting the work due to the loss of the ball in the middle as in the prior art. Further, since the ball is stored in a sealed state, it is possible to prevent adhesion of dust, and since it is a cartridge, it can be quickly replaced with a new one. Moreover, since it is made of glass, static electricity hardly occurs. Moreover, if it is transparent glass, the remaining amount can be visually recognized, and the remaining amount can be grasped more easily and reliably.

本発明を実施するための最良の形態は、底部に供給口を設けた樋状のホッパの直上に配設し、内部に充填したボールを落としながら該樋状のホッパに沿って移動するボール供給カートリッジであって、ガラスにより所要箇所に充填口を設けた口部が窄まるガラス瓶形の形態に成形してなるボール供給カートリッジにある。   The best mode for carrying out the present invention is a ball supply that is arranged directly above a bowl-shaped hopper provided with a supply port at the bottom, and moves along the bowl-shaped hopper while dropping a ball filled inside. The cartridge is a ball supply cartridge which is formed into a glass bottle shape in which a mouth portion provided with a filling port at a required location is narrowed by glass.

次に上記実施例によるボール供給動作について説明する。
先ず、一定量のボール１０２を充填したボール供給カートリッジ８をホルダー１１のホルダー本体１１Ｃにセットする。これにより該ボール供給カートリッジ８は横に倒した状態において樋状のホッパ３の一端側に運ばれ、端部に到達すると口を下にして倒立状態となり、内部に充填されたボール１０２を樋状のホッパ３に落下供給する。そしてこの状態において元の方向に戻り、樋状のホッパ３の長さ方向の全体或いは所要範囲までボールを供給する。次に、このようにしてボール１０２を供給された樋状のホッパ３は、図１０に示す如く、その底部の供給口４を所要の広さに開いて被供給体１０３上を水平に移動し、該被供給体１０３の上面にボール１０２を供給するものである。そして、ボール供給カートリッジ８内のボール１０２の残量が１回分の供給量に足りなくなったときに、新しいボール供給カートリッジに交換するものである。 Next, the ball supply operation according to the above embodiment will be described.
First, the ball supply cartridge 8 filled with a certain amount of balls 102 is set in the holder main body 11 </ b> C of the holder 11. As a result, the ball supply cartridge 8 is carried to one end side of the bowl-shaped hopper 3 in a state of being tilted sideways. The hopper 3 is dropped and supplied. In this state, the ball returns to the original direction, and the balls are supplied to the entire length direction or a required range of the bowl-shaped hopper 3. Next, the bowl-shaped hopper 3 supplied with the balls 102 in this way moves horizontally on the supply target 103 by opening the supply port 4 at the bottom to a required size as shown in FIG. The ball 102 is supplied to the upper surface of the supply target 103. Then, when the remaining amount of the balls 102 in the ball supply cartridge 8 becomes insufficient for one supply, the ball supply cartridge 8 is replaced with a new ball supply cartridge.
