- the movement distance of the movable table 22 varies by appropriately changing the execution order of the mounting operation and the imaging operation in each mounting group. This is due to the relationship between the corresponding mounting positions Mp and the distance from the suction nozzle 24 to the optical axis of the substrate camera 16. Therefore, the imaging control unit 33 sets a plurality of mounting groups based on the mounting positions Mp corresponding to the mounting operations MV1 to MV12 acquired in S21 and the execution order of the mounting operations, and calculates an execution pattern (S23).

That is, after the image data of the inspection component 50 is acquired by the imaging control unit 33, the mounting operation is temporarily stopped for a period until the pass / fail inspection result is input. The inspection support apparatus 90 uses this period to execute a preliminary operation for the next mounting operation.
- the display control unit 34 of the control device 30 displays the image data acquired by controlling the imaging process by the imaging control unit 33. It is displayed on the device 17. The worker refers to the displayed image data to determine whether the inspection component 50 is in a good state and inputs the result of the determination.

- the operation of the transfer device that moves the suction nozzle 24 from the current position NCp to above the mounting position Mp and moves the suction nozzle 24 up and down to mount the inspection component 50 held by the suction nozzle 24 at the mounting position Mp. Therefore, an operation executed in the order according to the control program is defined as a mounting operation.

- the imaging process of the board camera 16 is executed. In this imaging process, it is necessary to move the movable table 22 so that the inspection component 50 is within the camera field of view of the board camera 16.
- the mounting position Mp, the suction nozzle 24, and the substrate camera respectively corresponding to a plurality of mounting operations. It has been found that depending on the relationship with the distance to the sixteen optical axes, the moving distance of the moving base 22 becomes longer and the efficiency of the imaging process is reduced.

- necessary image data is efficiently acquired, so that the efficiency of inspection of the mounted state can be improved.
- an operation from when a plurality of electronic components supplied by the transfer device (component transfer device 13) are held until the mounting operation is repeated a number of times equal to the held number is defined as a mounting cycle.
- the imaging control unit 33 optimizes the execution order for the mounting operation included in the mounting cycle and the imaging operation corresponding to the mounting operation. According to such a configuration, the execution order of a plurality of mounting operations and a plurality of imaging operations is optimized with a mounting cycle as a unit. Therefore, when a plurality of inspection components 50 are included in an electronic component that is mounted in one mounting cycle, necessary imaging is performed while suppressing the effect on mounting processing in the mounting cycle without affecting other mounting cycles. Processing can be executed.

In contrast, the imaging control unit 33 may calculate the operation time (required time) required for the mounting operations MV1 to MV12 and the imaging operations IV1 to IV12 in the execution order for a plurality of execution patterns.
- the imaging control unit 33 selects the optimal execution order based on the required time when each execution order is executed in place of the movement distance of the moving table 22.

This includes the time required for acceleration and deceleration in the operation of the component transfer device 13 or the movement operation of the moving table 22 and the operation of the mounting head 23 (for example, the indexing operation of the suction nozzle 24). Can be executed in parallel.
- the imaging control unit 33 may be configured to optimize the execution order based on the required time. Thereby, the execution order of the mounting operation and the imaging operation can be optimized more accurately as compared with the case based on the moving distance of the moving table 22. Moreover, the aspect illustrated in embodiment is suitable from a viewpoint of reducing the processing load by optimization.
- the inspection support apparatus 90 sets one mounting cycle as an optimization target.

(1.部品実装機1の全体構成)
部品実装機1の構成について、図1を参照して説明する。部品実装機1は、図1に示すように、基板搬送装置11と、部品供給装置12と、部品移載装置13と、部品カメラ15と、基板カメラ16と、制御装置30とを備える。以下の説明において、部品実装機1の水平幅方向(図1の左上から右下に向かう方向)をX軸方向とし、部品実装機1の水平長手方向(図1の右上から左下に向かう方向)をY軸方向とし、X軸およびY軸に垂直な鉛直方向(図1の上下方向)をZ軸方向とする。
本実施形態において、検査を支援する検査支援装置90は、部品実装機1における基板カメラ16と、撮像制御部33とを備えて構成される。検査支援装置90は、部品実装機1が回路基板40への装着を行った電子部品のうち対象とされる検査部品50の装着状態の自動検査または目視検査を支援する。具体的には、検査支援装置90は、複数回の装着動作および複数回の撮像動作の動作順序を最適化することにより、上記の検査を支援する。
ここで、吸着ノズル24を現在位置NCpから装着位置Mpの上方へと移動させるとともに吸着ノズル24を昇降させて、当該吸着ノズル24に保持された検査部品50を装着位置Mpに装着する部品移載装置13の動作を「装着動作」と定義する。当該装着動作は、制御プログラムに従った順序で実行される。
部品実装機1による電子部品の実装処理について、図5を参照して説明する。実装処理において、実装制御部31は、先ず複数の吸着ノズル24に電子部品を順次吸着させて、電子部品を保持する吸着処理(ステップ11(以下、「ステップ」を「S」と表記する))を実行する。次に、撮像制御部33は、部品移載装置13の動作により装着ヘッド23を部品カメラ15の上方に移動させて、吸着された複数の電子部品を撮像する撮像処理(S12)を実行する。
検査支援装置90を構成する撮像制御部33による装着動作および撮像動作の実行順序の最適化処理について、図6および図7を参照して説明する。本実施形態において、撮像制御部33は、一の装着サイクルに含まれる装着動作および当該装着動作に対応する撮像動作を対象として実行順序を最適化する。また、装着サイクルでは、装着ヘッド23に支持される12本の吸着ノズル24の全てが電子部品を吸着して保持し、各電子部品がそれぞれ異なる装着位置Mpに装着される態様を例示する。
検査支援装置90は、実装制御部31による実装処理の実行中において、予め設定された条件に基づいて、複数回の装着動作および複数回の撮像動作の実行順序を最適化する処理を実行する。ここで、上記の予め設定された条件は、本実施形態において、装着予定の部品種別、現在時刻、実行された装着動作の回数、または前回の検査から現在までの時間である。
実施形態において、検査支援装置90は、供給位置Sに供給された電子部品を保持して回路基板40上の装着位置Mpまで当該電子部品を移載する移載装置(部品移載装置13)を備える部品実装機1に適用される。検査支援装置90は、回路基板40に装着された電子部品を対象として行われる装着状態の検査を支援する。移載装置は、基台2に対して相対移動可能に支持された移動台22と、電子部品を保持する吸着ノズル24を複数支持し、移動台22に設けられる装着ヘッド23と、を有する。
検査支援装置90は、回路基板40を撮像可能に移動台22に設けられたカメラ(基板カメラ16)と、部品実装機1による実装処理において電子部品のうち検査の対象とされる検査部品50が回路基板40に装着された場合に、カメラの撮像処理を制御して、当該検査部品50が収められた画像データを取得する撮像制御部33と、を備える。
吸着ノズル24を現在位置NCpから装着位置Mpの上方へと移動させるとともに吸着ノズル24を昇降させて、当該吸着ノズル24に保持された検査部品50を装着位置Mpに装着する移載装置の動作であって、制御プログラムに従った順序で実行される動作を装着動作と定義する。カメラが装着位置Mpに装着された検査部品50を撮像可能に、カメラを現在位置CCpから装着位置Mpの上方へと移動させる移載装置の動作を撮像動作と定義する。
撮像制御部33は、複数回の装着動作および複数回の撮像動作の実行順序を、当該実行順序における移動台22の移動距離、または当該実行順序における装着動作および撮像動作に要する動作時間に基づいて最適化する。
このような構成によると、装着サイクルを一単位として複数回の装着動作および複数回の撮像動作の実行順序が最適化される。よって、一の装着サイクルによって装着される電子部品に複数の検査部品50が含まれる場合に、他の装着サイクルに影響することなく、装着サイクルにおける実装処理への影響を抑制しつつ、必要な撮像処理を実行できる。
このような構成によると、例えば第二装着グループMg2により装着される複数の検査部品50同士の装着位置Mpが比較的近い場合に、これらの検査部品50に対応する装着動作を一連で実行するとともに、その後に複数の撮像動作を一連でまとめて実行する。これにより、撮像処理の実行による移動台22の移動距離を短くすることができる。
このような構成によると、例えば第一装着グループMg1における最後の装着動作に対応する装着位置Mpの上方に吸着ノズル24が位置する状態において、この状態での基板カメラ16の位置が、最初の装着位置Mpに対応する装着位置Mpよりも最後の装着動作に対応する装着位置Mpに近い場合に、これらの検査部品50に対応する装着動作を装着動作の逆順で実行する。これにより、撮像処理の実行による移動台22の移動距離を短くすることができる。
このような構成によると、装着グループMg3により装着される複数の検査部品50同士の装着位置Mpが比較的遠い場合に、これらの検査部品50に対応する装着動作と撮像動作を交互に実行する。これにより、撮像処理の実行によって、移動台22の移動距離が延びることが抑制される。
このような構成によると、特に装着精度が要求される部品種別の電子部品を検査対象としたり、定期的な検査を行ったりすることが可能となる。よって、回路基板40製品の品質が維持される。
このような構成によると、作業者による任意のタイミングで検査を行うことができる。これにより、回路基板40製品の品質が好適に維持される。
これにより、例えば装着状態が良好との結果が入力された場合には、吸着ノズル24を下降させて速やかに次の電子部品に係る装着動作を実行できる。よって、撮像処理の実行に伴うスループットの低下が抑制される。また、装着状態が不良との結果が入力された場合には、以降の装着動作が取り消されることによって、電子部品の浪費を防止することができる。
実施形態において、検査支援装置90の撮像制御部33は、S23で算出された複数の実行パターンについて、装着動作および撮像動作の実行順序における移動台22の移動距離を算出する(S24)。これに対して、撮像制御部33は、複数の実行パターンについて、実行順序における装着動作MV1~MV12および撮像動作IV1~IV12に要する動作時間(所要時間)を算出してもよい。
