Description

本発明は、装着ヘッドを交換可能にした部品装着機及びその使用方法に関する発明である。   The present invention relates to a component mounting machine in which a mounting head is replaceable and a method of using the same.

例えば、特許文献１（特開２００４−１０４０７５号公報）に記載された部品装着機は、回路基板を搬送するコンベアと、デバイスパレット上に多数のフィーダを搭載した部品供給装置と、ＸＹ移動機構（ＸＹロボット）に取り付けられた装着ヘッドと、部品供給装置とコンベアとの間に設置されたカメラ等を備え、フィーダから供給される部品を装着ヘッドの吸着ノズルで吸着して、その吸着部品をカメラで撮像して画像処理して部品識別を行った後、当該吸着部品をコンベア上の回路基板に装着するようになっている。
特開２００４−１０４０７５号公報 For example, a component mounting machine described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-104075) includes a conveyor that conveys a circuit board, a component supply device in which a large number of feeders are mounted on a device pallet, an XY moving mechanism ( A mounting head attached to the XY robot), a camera installed between the component supply device and the conveyor, and the component supplied from the feeder is sucked by the suction nozzle of the mounting head, and the sucked component is After picking up the image and processing the image to identify the component, the suction component is mounted on a circuit board on the conveyor.
JP 2004-104075 A

上記特許文献１の構成では、部品装着機の稼働中は、装着ヘッドを部品供給装置の吸着ステーションへ移動させて装着ヘッドの吸着ノズルで部品の吸着動作を行った後、一旦、装着ヘッドをカメラの上方位置（撮像ステーション）へ移動させて吸着部品をカメラで撮像し、撮像完了後に、装着ヘッドを回路基板の上方位置（装着ステーション）へ移動させて吸着部品を回路基板に装着し、装着完了後に、再び装着ヘッドを部品供給装置の吸着ステーションへ移動させて吸着動作を行うという動作を繰り返す。   In the configuration of the above-mentioned Patent Document 1, during operation of the component mounting machine, the mounting head is moved to the suction station of the component supply device, the component suction operation is performed by the suction nozzle of the mounting head, and then the mounting head is temporarily moved to the camera. Move the mounting part to the upper position (mounting station) of the circuit board after mounting the image and move the mounting head to the upper position of the circuit board (mounting station). Thereafter, the operation of moving the mounting head to the suction station of the component supply device and performing the suction operation again is repeated.

この構成では、装着ヘッドを吸着ステーションから装着ステーションへ移動させる途中で、一旦、装着ヘッドを撮像ステーションへ移動させなければならないため、吸着ステーションから装着ステーションまでの装着ヘッドの移動距離が長くなると共に、装着ヘッドを撮像ステーションで一旦停止させてカメラで吸着部品を撮像する時間が必要となるため、サイクルタイムが長くなり、生産性が低下する要因となる。   In this configuration, since the mounting head has to be moved to the imaging station in the middle of moving the mounting head from the suction station to the mounting station, the moving distance of the mounting head from the suction station to the mounting station is increased. Since it takes time to temporarily stop the mounting head at the imaging station and to pick up the suction component with the camera, the cycle time becomes longer and the productivity is lowered.

そこで、近年、吸着ノズルで吸着した部品を撮像するカメラを装着ヘッドに搭載したものがあり、このカメラ付きの装着ヘッドと、カメラ無しの装着ヘッドのいずれもＸＹ移動機構に交換可能に取り付けられるようにしたものがある。このカメラ付きの装着ヘッドをＸＹ移動機構に取り付けて使用する場合は、カメラと装着ヘッドとが一体に移動するため、吸着動作後に装着ヘッドを吸着ステーションから装着ステーションへ直に移動させながら、その移動中に装着ヘッドを停止させることなくカメラで吸着部品を撮像することが可能となり、サイクルタイムを短縮する効果が得られる。   Therefore, in recent years, there is a camera that mounts a camera for imaging a component sucked by a suction nozzle on the mounting head, and both the mounting head with the camera and the mounting head without the camera can be attached to the XY moving mechanism in a replaceable manner. There is something that was made. When using the mounting head with camera attached to the XY movement mechanism, the camera and mounting head move together, so the mounting head moves directly from the suction station to the mounting station after the suction operation. It is possible to take an image of the suction component with the camera without stopping the mounting head, and the effect of shortening the cycle time can be obtained.

このように、カメラ付きの装着ヘッドを使用する場合でも、部品供給装置とコンベアとの間には、本来不要なカメラ設置用の間隔があけられているため、装着ヘッドを吸着ステーションと装着ステーションとの間で移動させる際に、本来不要なカメラ設置用の間隔分だけ余分に装着ヘッドを移動させなければならず、その分、装着ヘッドの移動距離が長くなって、サイクルタイムを短縮する効果が少なくなってしまう。   In this way, even when using a mounting head with a camera, since there is an unnecessary space for camera installation between the component supply device and the conveyor, the mounting head is connected to the suction station and the mounting station. When moving between mounting heads, the mounting head must be moved by an extra interval for camera installation, which is essentially unnecessary, and the movement distance of the mounting head is increased, thereby reducing the cycle time. It will decrease.

本発明はこのような事情を考慮してなされたものであり、従ってその目的は、カメラ付きの装着ヘッドと、カメラ無しの装着ヘッドとを選択して取付可能にした部品装着機において、カメラ付きの装着ヘッドを使用する場合に、吸着ステーションと装着ステーションとの間の装着ヘッドの移動距離を従来より短くすることができて、サイクルタイムを短縮できる部品装着機及びその使用方法を提供することにある。   The present invention has been made in view of such circumstances. Therefore, the object of the present invention is to provide a component mounting machine in which a mounting head with a camera and a mounting head without a camera can be selected and mounted. To provide a component mounting machine and a method of using the same, which can shorten the moving time of the mounting head between the suction station and the mounting station when using the mounting head, and can shorten the cycle time. is there.

上記目的を達成するために、本発明は、回路基板を搬送するコンベアと、部品を供給する部品供給装置と、ＸＹ移動機構に交換可能に取り付けられた装着ヘッドとを備え、前記部品供給装置から供給される部品を前記装着ヘッドの吸着ノズルで吸着して前記コンベア上の回路基板に装着する部品装着機及びその使用方法において、前記部品供給装置と前記コンベアとの間に、前記吸着ノズルで吸着した部品を撮像する第１カメラが脱着可能に設置され、前記ＸＹ移動機構には、前記吸着ノズルで吸着した部品を撮像する第２カメラを搭載した第２カメラ付きの装着ヘッドと、カメラ無しの装着ヘッドのいずれも取付可能であり、前記部品供給装置の固定位置は、該部品供給装置と前記コンベアとの間に前記第１カメラを設置可能な間隔をあける第１固定位置と、前記第１カメラを取り外したときに前記部品供給装置と前記コンベアとの間隔を狭める第２固定位置とを選択可能に構成されている。   In order to achieve the above object, the present invention comprises a conveyor for transporting a circuit board, a component supply device for supplying components, and a mounting head attached to an XY moving mechanism in a replaceable manner, from the component supply device. In a component mounting machine for sucking a component to be supplied by a suction nozzle of the mounting head and mounting the component on a circuit board on the conveyor, and a method for using the same, the suction nozzle sucks the component between the component supply device and the conveyor. A first camera that captures the imaged part is detachably installed, and the XY movement mechanism includes a mounting head with a second camera that mounts a second camera that captures an image of the part adsorbed by the adsorption nozzle, and no camera Any of the mounting heads can be attached, and the fixing position of the component supply device is set at an interval at which the first camera can be installed between the component supply device and the conveyor. A first fixed position, the is selectably component supply device and a second fixing position to narrow the distance between the conveyor when removed the first camera.

この構成では、ＸＹ移動機構に前記カメラ無しの装着ヘッドを取り付けて使用する場合は、前記部品供給装置を前記第１固定位置に固定して該部品供給装置と前記コンベアとの間に前記第１カメラを設置し、この状態で、前記部品供給装置から供給される部品を前記カメラ無しの装着ヘッドの吸着ノズルで吸着して、その吸着部品を前記第１カメラで撮像して画像処理するようにすれば良い。一方、ＸＹ移動機構に前記第２カメラ付きの装着ヘッドを取り付けて使用する場合は、前記部品供給装置と前記コンベアとの間から前記第１カメラを取り外して前記部品供給装置を前記第２固定位置に固定して該部品供給装置と前記コンベアとの間隔を狭め、この状態で、前記部品供給装置から供給される部品を前記第２カメラ付きの装着ヘッドの吸着ノズルで吸着して、その吸着部品を前記第２カメラで撮像して画像処理するようにすれば良い。   In this configuration, when the mounting head without a camera is attached to the XY movement mechanism, the component supply device is fixed at the first fixed position, and the first supply portion is interposed between the component supply device and the conveyor. A camera is installed, and in this state, the component supplied from the component supply device is sucked by the suction nozzle of the mounting head without the camera, and the sucked component is imaged by the first camera for image processing. Just do it. On the other hand, when the mounting head with the second camera is attached to the XY moving mechanism, the first camera is removed from between the component supply device and the conveyor, and the component supply device is moved to the second fixed position. In this state, the parts supplied from the parts supply device are sucked by the suction nozzle of the mounting head with the second camera, and the suction parts are fixed. May be captured and image processed by the second camera.

このようにすれば、第２カメラ付きの装着ヘッドを使用する場合に、前記第１カメラを取り外して部品供給装置とコンベアとの間隔を狭めることができるため、吸着ステーションと装着ステーションとの間の装着ヘッドの移動距離を従来より短くすることができて、サイクルタイムを短縮することが可能となり、生産性を向上することができる。   In this way, when the mounting head with the second camera is used, the first camera can be removed and the interval between the component supply device and the conveyor can be narrowed. The moving distance of the mounting head can be made shorter than before, the cycle time can be shortened, and the productivity can be improved.
