Description

検査方法、検査システム及びプログラムInspection method, inspection system and program
　本発明は、部品が搭載される物品の検査に係る技術分野に属する。 The present invention belongs to the technical field related to inspection of articles on which components are mounted.
　基板に対する部品の実装状態などを検査する装置として、自動外観検査装置が広く使われている。このような装置では、部品が実装された基板（はんだ付けの前の状態のものも含む）の外観情報がセンサにより取得され、部品毎にその部品に応じた項目の計測が行われる。そして、得られた結果を所定の検査基準と照合することにより、良品・不良品の判別が行われる。 自動 Automatic visual inspection equipment is widely used as an equipment for inspecting the mounting state of components on a board. In such an apparatus, the appearance information of the board on which the component is mounted (including the board before soldering) is acquired by the sensor, and the measurement of items corresponding to the component is performed for each component. Then, by comparing the obtained result with a predetermined inspection standard, a non-defective product / defective product is determined.
　ここで、設定される検査項目や検査基準が適切なもので無ければ、実際には良品であるものを不良品と判断する「見過ぎ」や、実際には不良品であるものを良品と判断する「見逃し」が発生する。「見過ぎ」は検査効率の悪化を招き、「見逃し」は製造工程の信頼性を低下させ後工程における作業効率を悪化させる。そして、いずれも製造工程の費用を増大させる原因となるため、「見過ぎ」及び「見逃し」は最小化させることが望ましい。 Here, if the set inspection items and inspection criteria are not appropriate, it is judged that a product that is actually good is a defective product. "Missing" occurs. "Overlooking" causes deterioration of inspection efficiency, and "overlooking" lowers reliability of the manufacturing process and deteriorates work efficiency in a post-process. In addition, it is desirable to minimize “overlooking” and “overlooking” because each of these causes an increase in the cost of the manufacturing process.
　しかしながら、「見逃し」を減少させるために検査基準を厳しくすると「見過ぎ」が増加し、「見過ぎ」を減少させるために検査基準を緩和すると「見逃し」が増加することになるため、適切な検査項目及び検査基準を設定する必要がある。 However, if the inspection standards are tightened to reduce “oversight”, “oversight” will increase, and if the inspection standards are relaxed to reduce “oversight”, “oversight” will increase. Inspection items and inspection criteria need to be set.
　このため、量産品における検査の実施に先立ち、基板や部品の検証画像で検査項目や検査基準の調整が行われ、この調整の完了後に前述の検査項目や検査基準が実際の生産ラインに適用される。しかしながら、従来は、一つの基板上に配置された全ての部品品番に対する検査項目や検査基準の調整後に、量産検査で実施できるように量産プログラムに展開されていたため、部品品番によっては品質が一定しないものも存在し得、「見過ぎ」や「見逃し」が発生する場合があった。 For this reason, prior to conducting inspections on mass-produced products, inspection items and inspection standards are adjusted using verification images of boards and components, and after these adjustments are completed, the aforementioned inspection items and inspection standards are applied to actual production lines. You. However, conventionally, after adjusting the inspection items and inspection standards for all the part numbers arranged on one board, it is developed in a mass production program so that it can be executed in mass production inspection. Therefore, the quality is not constant depending on the part number. Things could also be present, and "too much" or "missing" could occur.
　ここで、部品毎のデータの信頼性を認識可能とする技術に関して、電子部品装着装置のパターンプログラムに使用する電子部品の部品ライブラリのデータを作成するときに、作成状態によって信頼度のランク分けを行い、ランク分けした作成状態を当該データに付加することで、段取り作業時等に、部品ライブラリを使用する場合に、どの電子部品が信頼できるものかどうかが一目で分かるようにする技術が提案されている（特許文献１参照）。しかしながら、上記の従来技術は、基板検査等における検査項目や検査基準を部品毎に最適化することを可能とするものではなかった。 Here, regarding the technology that enables the reliability of data for each component to be recognized, when creating data of a component library of electronic components used in a pattern program of an electronic component mounting apparatus, the reliability is classified according to the creation state. A technology has been proposed that adds a rank-classified creation status to the data to make it possible to see at a glance which electronic components are reliable when using a component library during setup work. (See Patent Document 1). However, the above-described conventional technology does not make it possible to optimize inspection items and inspection standards in substrate inspection and the like for each component.
　また、上述のように、量産品における検査の実施に先立ち、基板や部品の検証画像で検査項目や検査基準の調整を行う場合に、検査項目や検査基準の信頼性をどの程度向上させてから生産工程に適用するかは重要な問題となる。例えば、検査項目や検査基準をリビジョン管理し、いずれのリビジョンを生産工程に適用するかについて、調整に関わったユーザが決定することが考えられるが、操作が煩雑になり、システムの汎用性を減殺する場合があった。また、単純に最新リビジョンを生産工程に適用した場合には、必ずしも適切でない検査項目や検査基準が適用されてしまう場合があった。 In addition, as described above, prior to conducting inspections on mass-produced products, when adjusting inspection items and inspection standards with verification images of boards and components, how much the reliability of the inspection items and inspection standards should be improved An important issue is whether to apply it to the production process. For example, it is conceivable that the user involved in the adjustment manages the revision of inspection items and inspection standards and decides which revision is applied to the production process, but the operation becomes complicated and the versatility of the system is reduced. There was a case. In addition, when the latest revision is simply applied to the production process, an inappropriate inspection item or inspection standard may be applied.

＜実施例１＞
　次に、本発明の実施例１について詳細に説明する。図３には、本実施例における品番データテーブル３０の例を示す。この品番データテーブル３０は、先述のように、データ管理用サーバ２の部品情報記憶部２２及び、検査情報記憶部２４に記憶された情報を基に、品番データ処理部１３において作成し、出力部１０１により表示される。品番データテーブル３０は、検査すべき基板に搭載される部品の各々に対応する品番ＩＤと、各品番ＩＤに対応する品番データ群が記録されたテーブルである。図３においては、品番ＩＤ００１が付されたチップ抵抗である部品１６０８ＲＳと、品番ＩＤ００２が付されたＱＦＰ（ＱｕａｄＦｌａｔ Ｐａｃｋａｇｅ）である部品ＱＦＰ４８４８についての品番データ群が表示されている。このように、複数の品番ＩＤに係る部品の品番データ群を合わせたものが本実施例における品番データテーブルである。 <Example 1>
Next, Embodiment 1 of the present invention will be described in detail. FIG. 3 shows an example of the product number data table 30 in the present embodiment. The part number data table 30 is created in the part number data processing unit 13 based on the information stored in the part information storage unit 22 and the inspection information storage unit 24 of the data management server 2 and output to the output unit as described above. Displayed by 101. The part number data table 30 is a table in which a part number ID corresponding to each component mounted on the board to be inspected and a part number data group corresponding to each part number ID are recorded. FIG. 3 shows a part number data group for a part 1608RS, which is a chip resistor with a part number ID001, and a part QFP4848, which is a QFP (QuadFlat Package) with a part number ID002. As described above, the combination of the part number data groups of the parts related to the plurality of part number IDs is the part number data table in the present embodiment.
　ここで、品番ＩＤ００１に係る部品の品番データ群について詳細に説明する。本実施例では、品番ＩＤ００１に係る部品について形状、部品種、検査項目、検査基準などが記録されている。検査基準は、検査における搭載部品の良・不良の判断の閾値や判断指標である。そして、品番ＩＤ００１に係る部品について検査項目や検査基準が変更される毎に、品番データ群のリビジョンが更新され各品番ＩＤに対応する欄の最上段に記載される。図３における品番ＩＤ００１に係る部品については、検査項目や検査基準に対して１１回の変更が加えられ、最新のリビジョンはリビジョン１２であることが分かる。 Here, the part number data group of the part related to the part number ID001 will be described in detail. In the present embodiment, a shape, a component type, an inspection item, an inspection standard, and the like are recorded for the component associated with the part number ID001. The inspection criterion is a threshold or a judgment index for judging the quality of the mounted component in the inspection. Then, each time the inspection item or inspection standard is changed for the part related to the part number ID 001, the revision of the part number data group is updated and described at the top of the column corresponding to each part number ID. Regarding the part corresponding to the part number ID 001 in FIG. 3, the inspection item and the inspection standard are changed 11 times, and it can be seen that the latest revision is the revision 12.
　また、本実施例の品番データテーブルでは、各部品に対応する品番データ群には、各リビジョン毎に品質レベル及び展開可否のデータが含まれている。この品質レベルは、各リビジョンにおける品番データ群の検査項目や検査基準の品質または信頼性が、検査装置３における検査に使用し得るレベルか否かを示す指標である。例えば品質レベルがＮＧである場合とは、作成途中の品番データ群であり実際の検査には使用不可のレベルであることを示す。また、品質レベルがＴＲＹである場合は、特定の検査プログラムに検査項目や検査基準の検査情報を展開して信頼性の確認をしている品番データ群であり、もうすぐ量産適用が可能となるレベルになることを示す。さらに、品質レベルがＯＫである場合は、特定の検査プログラムに検査項目や検査基準の検査情報が展開され信頼性の確認が終了した品番データ群であり、量産適用が可能なレベルであることを示す。 In the part number data table of the present embodiment, the part number data group corresponding to each component includes data of the quality level and the availability of development for each revision. This quality level is an index indicating whether the quality or reliability of the inspection item or inspection standard of the product number data group in each revision is at a level that can be used for inspection by the inspection device 3. For example, a case where the quality level is NG indicates that the part number data group is being created and cannot be used for actual inspection. When the quality level is TRY, it is a part number data group in which the inspection information of inspection items and inspection standards is developed in a specific inspection program and the reliability is confirmed, and the level at which mass production can be applied soon Indicates that Further, when the quality level is OK, it is a part number data group in which inspection information of inspection items and inspection standards is developed in a specific inspection program and the reliability has been confirmed, and it is a level that can be applied to mass production. Show.
　また、展開可否データは、各リビジョンの品番データ群を全ての検査プログラムに適用するか否かを示す指標である。展開可否データがＯＦＦの場合には、当該リビジョンの品番データ群は全ての検査プログラムに適用されない。展開可否データがＯＮの場合には、当該リビジョンの品番データ群は全ての検査プログラムに展開される。この展開可否データは、品質レベルデータとは独立にユーザが設定することができる。なお、図３において品質レベルデータは検査品質レベル情報に相当する。展開可否データは参照有無情報に相当する。 (4) The deployment availability data is an index indicating whether or not the part number data group of each revision is applied to all inspection programs. When the development availability data is OFF, the part number data group of the revision is not applied to all inspection programs. If the development availability data is ON, the part number data group of the revision is developed in all inspection programs. The development availability data can be set by the user independently of the quality level data. In FIG. 3, the quality level data corresponds to inspection quality level information. The expandability data corresponds to reference presence / absence information.
　次に、図４には、本実施例における検査プログラムに対する、品番参照データテーブルの例を示す。本実施例に係る検査システム９では、前述のように複数の検査プログラムを用いて、基板上の複数の部品についての検査を行っている。図４では、多くの検査プログラムのうち検査プログラム１及び２に対する品番参照データテーブル３５ａ及び３５ｂを示している。品番参照データテーブル３５ａ、３５ｂにおいては、基板における複数の回路に付された回路ＩＤ、各回路ＩＤが付された回路に搭載された部品の品番ＩＤ、各品番ＩＤが付された部品の搭載位置、各品番ＩＤに係る品番データ群のうち参照するリビジョンである参照リビジョン、参照リビジョンの品番データ群における品質レベル、展開可否、各品番ＩＤに係る品番データ群の最新リビジョン、最新リビジョンの品番データ群における品質レベル及び展開可否データ、品番データ群の状態である品番展開のステータスが表示されている。 FIG. 4 shows an example of a part number reference data table for the inspection program according to the present embodiment. In the inspection system 9 according to the present embodiment, a plurality of components are inspected on the board by using a plurality of inspection programs as described above. FIG. 4 shows part number reference data tables 35a and 35b for inspection programs 1 and 2 among many inspection programs. In the part number reference data tables 35a and 35b, the circuit IDs assigned to the plurality of circuits on the board, the part numbers of the parts mounted on the circuits assigned with the circuit IDs, and the mounting positions of the parts assigned with the part number IDs , A reference revision which is a revision to be referenced in the part number data group related to each part number ID, a quality level in the reference revision part number data group, expandability, a latest revision of the part number data group related to each part number ID, a part number data group of the latest revision , The status of the part number development, which is the state of the part number data group, is displayed.
　図４（ａ）に示す、検査プログラム１に対する品番参照データテーブル３５ａによれば、回路ＩＤ１～４に係る回路には、品番ＩＤ００１に係る部品が使用されており、基板における当該部品の搭載位置がＬｅｆｔ、Ｔｏｐである点、当該部品についての品番データ群の最新リビジョンはリビジョン１２である点が分かる。また、リビジョン１２の品番データ群は、現在、品質レベルとしてＮＧであるが展開可否についてはＯＮとされており、更新が必要である点が分かる。さらに、検査プログラム１は、最新リビジョンの品番データ群ではなく、リビジョン９の品番データ群を参照している点、リビジョン９の品番データ群は、現在、品質レベルとしてＯＫであり展開可否はＯＮであることが分かる。 According to the part number reference data table 35a for the inspection program 1 shown in FIG. 4A, the parts corresponding to the part number ID001 are used in the circuits corresponding to the circuit IDs 1 to 4, and the mounting position of the part on the board is determined. It can be seen that they are Left and Top, and that the latest revision of the part number data group for the part is revision 12. Further, the part number data group of the revision 12 is currently NG as the quality level, but the ON / OFF is set as to whether or not the development is possible, and it can be seen that the update is necessary. In addition, the inspection program 1 refers to the part number data group of the revision 9 instead of the part number data group of the latest revision. The part number data group of the revision 9 is currently OK as the quality level, and the deployment possibility is ON. You can see that there is.
　すなわち、本実施例における検査システム９では、基板上の各部品に対する検査項目と検査基準は、品番データ群により管理されている。そして、品番データ群は、その検査項目、検査基準とともに、品番データ群自体の品質レベル、展開可否をリビジョン毎に管理されている。そして、各検査プログラムにおいて参照される品番データ群が、品番参照データテーブルにより管理されている。 In other words, in the inspection system 9 according to the present embodiment, the inspection items and the inspection criteria for each component on the board are managed by a part number data group. The part number data group is managed for each revision, along with the inspection items and inspection standards, the quality level of the part number data group itself, and whether or not it can be developed. A part number data group referred to in each inspection program is managed by a part number reference data table.
　次に、図５を用いて、本実施例の検査システム９における、品番データ群の品質レベル、展開可否の内容の管理フローについて説明する。本フローは制御端末１のメモリ１０３に記憶されるようにしてもよく、入力部１０２から、新規品番データ群を作成する旨の入力がなされた場合に全てのステップが自動的に実行されるようにしてもよい。図５は、検査情報管理ルーチンのフローチャートである。本フローが実行されると、まず、ステップＳ１０１において、新規の検査対象部品について品番が作成される。品番が作成されると、当該品番に対応する品番データ群が生成される。この状態の品番データ群においては、品番レベルはＮＧ、展開可否はＯＦＦに設定される。 Next, referring to FIG. 5, a description will be given of a management flow of the quality level of the part number data group and the contents of the possibility of development in the inspection system 9 of the present embodiment. This flow may be stored in the memory 103 of the control terminal 1, and all steps are automatically executed when an input to create a new part number data group is made from the input unit 102. It may be. FIG. 5 is a flowchart of the inspection information management routine. When this flow is executed, first, in step S101, a part number is created for a new inspection target component. When a product number is created, a product number data group corresponding to the product number is generated. In the part number data group in this state, the part number level is set to NG, and the availability is set to OFF.
　ステップＳ１０２においては、作成された品番データ群に対応するウィンドウ画面が自動的に作成され制御端末１の出力部１０１に表示される。さらにステップＳ１０３において作成された品番データ群に対応する部品の良品モデル画像、不良品実績画像の他、部品の形状、部品種、現時点で仮に設定された検査項目及び検査基準などが部品情報記憶部２２に登録される。このことにより、図３の品番データテーブル３０における品番名、形状、部品種、検査項目、検査基準等が表示される。 In step S102, a window screen corresponding to the created part number data group is automatically created and displayed on the output unit 101 of the control terminal 1. Further, in addition to the good part model image and the defective part result image of the part corresponding to the part number data group created in step S103, the part information, the part shape, the part type, the inspection item and the inspection reference temporarily set at the present time, and the like are stored. 22. As a result, the product name, shape, component type, inspection item, inspection standard, and the like in the product number data table 30 of FIG. 3 are displayed.
　次にステップＳ１０４においては、検証画像が登録される。より具体的には、ステップＳ１０３の処理において登録された検査項目及び検査基準によって「見過ぎ」または「見逃し」が発生するか否かを事前検証するためのサンプルの画像が登録される。ステップＳ１０４の処理が終了するとステップＳ１０５に進む。ステップＳ１０５においては、品番調整が行われる。すなわち、ステップＳ１０４で登録された検証画像に対して、適切と思われる検査項目及び検査基準が調整される。ステップＳ１０５の処理が終了するとステップＳ１０６に進む。 Next, in step S104, a verification image is registered. More specifically, a sample image for pre-verification as to whether “overlooking” or “overlooking” occurs according to the inspection item and inspection standard registered in the process of step S103 is registered. When the process in step S104 ends, the process proceeds to step S105. In step S105, a product number adjustment is performed. That is, the inspection item and the inspection standard that are considered appropriate are adjusted with respect to the verification image registered in step S104. When the process in step S105 ends, the process proceeds to step S106.
　ステップＳ１０６においては、ステップＳ１０４で登録した検証画面に対して「見過ぎ」あるいは「見逃し」がなかったか否かが判定される。ここで、「見過ぎ」あるいは「見逃し」が発生した場合には、品番データ群における検査項目または検査基準が適切ではないと判定されるので、ステップＳ１０５の処理の前に戻り、さらにこれらの調整が行われる。そして、ステップＳ１０６において、検証画面について「見過ぎ」も「見逃し」も発生しなくなるまで、ステップＳ１０５及びステップＳ１０６の処理が繰り返し行われる。 In step S106, it is determined whether or not “overlooked” or “missed” has not occurred on the verification screen registered in step S104. Here, if "overlooking" or "overlooking" occurs, it is determined that the inspection item or inspection standard in the part number data group is not appropriate, so that the process returns to the process of step S105, and further adjustment of these items is performed. Is performed. Then, in step S106, the processing of steps S105 and S106 is repeated until neither "overlooking" nor "missing" occurs on the verification screen.
　ステップＳ１０６において、検証画面について「見過ぎ」も「見逃し」も発生しなくなった際には、ステップＳ１０７に進む。ステップＳ１０７においては、ユーザにより、品質レベルがＴＲＹに変更される。ステップＳ１０７の処理が終了するとステップＳ１０８に進む。ステップＳ１０８においては、品番データ群が、特定の検査プログラムに適用される。より詳細には、出力部１０１に表示された別ウィンドウにおいて、当該品番データ群が適用される特定の検査プログラムを指定するようにしてもよい。これにより、特定の検査プログラムの品番参照データテーブルにおいて、当該品番データ群に対応する展開可否がＯＮに設定される。なお、特定の検査プログラムは一つであっても二つ以上であってもよい。 に お い て If no “overlook” or “overlook” has occurred in the verification screen in step S106, the process proceeds to step S107. In step S107, the quality level is changed to TRY by the user. When the process in step S107 ends, the process proceeds to step S108. In step S108, the part number data group is applied to a specific inspection program. More specifically, a specific inspection program to which the part number data group is applied may be specified in another window displayed on the output unit 101. As a result, in the part number reference data table of the specific inspection program, whether or not development is possible is set to ON corresponding to the part number data group. In addition, the specific inspection program may be one or two or more.
　ステップＳ１０８の処理が終了するとステップＳ１０９に進む。ステップＳ１０９においては、ステップＳ１０８において適用の処理がなされた検査プログラムを用いて検査装置３において基板検査が実施される。そして、ステップＳ１１０において、ステップＳ１０９で行われた検査で「見過ぎ」または「見逃し」が発生したか否かが判定される。ここで「見過ぎ」または「見逃し」が発生したと判定された場合には、ステップＳ１０９の処理に戻り、検査項目や検査基準の調整を再度行う。一方、「見過ぎ」または「見逃し」が発生しないと判定された場合には、ステップＳ１１１に進む。 す る と When the process of step S108 ends, the process proceeds to step S109. In step S109, a board inspection is performed in the inspection apparatus 3 using the inspection program subjected to the processing applied in step S108. Then, in step S110, it is determined whether or not “too much” or “missing” has occurred in the inspection performed in step S109. If it is determined that “overlook” or “overlook” has occurred, the process returns to step S109, and the inspection items and inspection standards are adjusted again. On the other hand, when it is determined that “too much” or “missing” does not occur, the process proceeds to step S111.
　ステップＳ１１１では、当該品番データをさらに多くの複数の検査プログラムに適用して、検査装置３において複数の検査を実施する。ステップＳ１１１の処理が終了するとステップＳ１１２に進む。そして、ステップＳ１１２においては、ステップＳ１１１の複数の検査において「見過ぎ」または「見逃し」が発生したか否かが判定される。ステップＳ１１２において「見過ぎ」または「見逃し」が発生した場合には、ステップＳ１１１の処理に戻り、検査項目や検査基準の調整を再度行う。一方、「見過ぎ」または「見逃し」が発生しないと判定された場合には、ステップＳ１１３に進む。 In step S111, the part number data is applied to a larger number of inspection programs, and the inspection device 3 performs a plurality of inspections. When the process in step S111 ends, the process proceeds to step S112. Then, in step S112, it is determined whether "overlooking" or "missing" has occurred in the plurality of inspections in step S111. If "too much" or "missing" has occurred in step S112, the process returns to step S111, and the inspection items and inspection standards are adjusted again. On the other hand, if it is determined that “too much” or “missing” does not occur, the process proceeds to step S113.
　ステップＳ１１３においては、当該品番データ群における品質レベルをＯＫに設定し、且つ展開可否をＯＮに設定する。これで、当該品番データ群を参照すべき全ての検査プログラムに当該品番データ群が適用可能になる。ステップＳ１１３の処理が終了すると、ステップＳ１１４に進む。ステップＳ１１４では、当該品番データ群が全検査プログラムに適用される。 (4) In step S113, the quality level in the part number data group is set to OK, and whether or not development is set to ON. Thus, the part number data group can be applied to all inspection programs to which the part number data group should be referred. When the process in step S113 ends, the process proceeds to step S114. In step S114, the part number data group is applied to all inspection programs.
　ここで、当該品番データ群を全検査プログラムに適用する際に、前述にように、「条件付き一括更新」が行われる。その場合には、出力部１０１には、「リニューアル」ボタンが表示され、ユーザが、「リニューアル」ボタンをクリックすることで、「条件付き一括更新」が行われる。本実施例では、「条件付き一括更新」の条件としては、展開可否がＯＮであり、品質レベルがＯＫであることに設定されており、全ての検査プログラムにおいて、この条件を満たす中で、最新リビジョンの品番データ群の内容が適用される。この「条件付き一括更新」の条件は所定条件に相当する。また、展開可否と、品質レベルは「所定の検査情報」に相当する。 Here, when applying the part number data group to all the inspection programs, “conditional batch update” is performed as described above. In this case, a “renewal” button is displayed on the output unit 101, and the “conditional batch update” is performed by the user clicking the “renewal” button. In the present embodiment, the conditions of the “conditional batch update” are set such that deployment is ON and the quality level is OK. In all inspection programs, the latest The content of the revision part number data group is applied. The condition of “conditional batch update” corresponds to a predetermined condition. In addition, the availability and the quality level correspond to “predetermined inspection information”.
　ステップＳ１１４の処理が終了すると、本ルーチンを一旦終了する。なお、本実施例における検査情報管理ルーチンのステップＳ１０１、Ｓ１０７、Ｓ１１３は設定ステップに相当する。また、ステップＳ１０６、Ｓ１１０、Ｓ１１２は判定ステップに相当する。また、ステップＳ１１４は参照データ更新ステップに相当する。 (4) When the process of step S114 is completed, the present routine is ended once. Steps S101, S107, and S113 of the inspection information management routine according to the present embodiment correspond to setting steps. Steps S106, S110, and S112 correspond to a determination step. Step S114 corresponds to a reference data updating step.
　図５に記載されたフローチャートの右側には、各ステップが実行される段階での品番データ群における品質レベル及び展開可否の設定について示す。これによると、ステップＳ１０１において新規品番が作成された際には、品質レベルはＮＧ、展開可否はＯＦＦに設定される。その後、ステップＳ１０５における、検証画像を用いた品番データ群の調整において、「見過ぎ」や「見逃し」が発生しなかった場合には、ステップＳ１０７において、品質レベルはＴＲＹに、展開可否はＯＦＦに設定される。そして、複数の検査プログラムにおいて「見過ぎ」や「見逃し」が発生しなかった場合には、ステップＳ１１３において、品質レベルはＯＫに、展開可否はＯＮに設定される。 (5) The right side of the flowchart shown in FIG. 5 shows the setting of the quality level and the possibility of development in the part number data group at the stage when each step is executed. According to this, when a new product number is created in step S101, the quality level is set to NG, and the availability is set to OFF. Thereafter, in the adjustment of the part number data group using the verification image in step S105, if "overlooking" or "missing" has not occurred, in step S107, the quality level is set to TRY and the development possibility is set to OFF. Is set. Then, if “overlooking” or “overlooking” has not occurred in the plurality of inspection programs, in step S113, the quality level is set to “OK” and the development possibility is set to “ON”.
　図６には、上記のフローでも説明したように、品番データ群の検査項目や検査基準の調整検討を進め、品番の品質レベルがＯＫに達した場合の、品番参照データテーブルの変化について示す。図６は、検査プログラム１及び２についての品番参照データテーブルを示す。図６（ａ）は、「条件付き一括更新」を行う前の品番参照データテーブルを、図６（ｂ）は、「条件付き一括更新」を行った後の品番参照データテーブルを示す。 FIG. 6 shows changes in the part number reference data table when the examination of the inspection items and inspection standards of the part number data group is advanced and the quality level of the part number reaches OK, as described in the above flow. FIG. 6 shows a part number reference data table for the inspection programs 1 and 2. FIG. 6A shows a part number reference data table before performing “conditional batch update”, and FIG. 6B shows a part number reference data table after performing “conditional batch update”.
　図６（ａ）では、品番ＩＤ００１に係る部品について、検査プログラム１においてはリビジョン５が参照され、検査プログラム２においては、リビジョン６が参照されている。そして、リビジョン５においては、品番データ群の品質レベルはＴＲＹに設定されており、リビジョン６においては、品番データ群の品質レベルはＯＫに設定されている。また、リビジョン５においても、リビジョン６においても、展開可否はＯＮに設定されていることが分かる。また、品番ＩＤ００１の部品の品番データ群については、最新リビジョンがリビジョン７であり、リビジョン７の品質レベルは既にＯＫ、展開可否は既にＯＮに設定されている。すなわち、リビジョン７は既に完成した品番データ群であることが分かる。 6 (a), the inspection program 1 refers to the revision 5 and the inspection program 2 refers to the revision 6 for the part associated with the part number ID001. In revision 5, the quality level of the part number data group is set to TRY, and in revision 6, the quality level of the part number data group is set to OK. In addition, it can be seen that in both the revision 5 and the revision 6, the deployment availability is set to ON. As for the part number data group of the part having the part number ID 001, the latest revision is the revision 7, the quality level of the revision 7 has already been set to OK, and the availability of the development has already been set to ON. That is, it can be seen that the revision 7 is a completed product number data group.
　この状態で、品番ＩＤ００１の品番データ群について、「条件付き一括更新」を行う。より具体的には、別ウィンドウを出力部１０１に表示させ、当該別ウィンドウにおいて、検査プログラム１について、「リニューアル」ボタンをクリックするようにしてもよい。ここで、本実施例において、品番ＩＤ００１の品番データ群について、「条件付き一括更新」されるための条件は、展開可否がＯＮ、品質レベルがＯＫとなっていることである。 で In this state, “conditional batch update” is performed for the part number data group with the part number ID 001. More specifically, another window may be displayed on the output unit 101, and the “renewal” button for the inspection program 1 may be clicked in the another window. Here, in the present embodiment, the condition for “conditional batch update” of the part number data group of the part number ID 001 is that the development permission is ON and the quality level is OK.
　そうすると、図６（ｂ）に示すように、検査プログラム１においても、検査プログラム２においても、最新リビジョンであるリビジョン７の品番データ群が参照されるようになり、品質レベルはＯＫと変更される。このように、本実施例においては、品番データ群について、「条件付き一括更新」によって、所定条件を満たす中で最新の品番データ群を、一括して全検査プログラムに適用することが可能で、効率的に最適な検査項目と検査基準を適用することが可能となっている。 Then, as shown in FIG. 6B, in the inspection program 1 and the inspection program 2, the part number data group of the latest revision 7 is referred to, and the quality level is changed to OK. . As described above, in the present embodiment, with respect to the part number data group, the latest part number data group that satisfies the predetermined condition can be collectively applied to all inspection programs by “conditional batch update”. It is possible to apply optimal inspection items and inspection standards efficiently.
　なお、本実施例において、「条件付き一括更新」の条件は、展開可否がＯＮ、品質レベルがＯＫとなっていることであるが、他の条件を設定することも可能である。品番データ群の検査情報の信頼性が充分に高くなり、品番データ群が完成して初めて展開可否をＯＮにするような場合には、条件は、展開可否がＯＮだけでも充分である。 In the present embodiment, the condition of “conditional batch update” is that deployment is ON and the quality level is OK, but other conditions can be set. In the case where the reliability of the inspection information of the part number data group is sufficiently high and the development permission / inhibition is turned ON only after the completion of the part number data group, the condition that the development permission / inhibition is ON is sufficient.
　また、本実施例において、検査システム９が複数のユーザによって使用可能となっている場合に、特定のユーザによって品番データ群の品質レベルがＮＧまたは、ＴＲＹに設定された場合、他のユーザによって品質レベルがＯＫに変更されることを制限してもよい。より具体的には、特定のユーザ以外のユーザによって品質レベルがＯＫに変更されることを一切禁止してもよいし、特定の他のユーザ、例えば上記特定のユーザの上司等によってのみ、変更されることが許可されるようにしてもよい。 Further, in this embodiment, when the inspection system 9 is enabled by a plurality of users, when the quality level of the part number data group is set to NG or TRY by a specific user, the quality is set by another user. The change of the level to OK may be restricted. More specifically, the quality level may be prohibited from being changed to OK by a user other than the specific user at all, or may be changed only by a specific other user, for example, the manager of the specific user. May be permitted.
　また、同様に、検査システム９が複数のユーザによって使用可能となっている場合に、特定のユーザによって品番データ群の展開可否がＯＦＦに設定された場合、他のユーザによって展開可否がＯＮに変更されることを制限してもよい。より具体的には、特定のユーザ以外のユーザによって展開可否がＯＮに変更されることを一切禁止してもよいし、特定の他のユーザ、例えば上記特定のユーザの上司等によってのみ、変更されることが許可されるようにしてもよい。 Similarly, when the inspection system 9 is available for use by a plurality of users, if the development permission / prohibition of the part number data group is set to OFF by a specific user, the development permission / prohibition is changed to ON by another user. May be restricted. More specifically, it is possible to completely prohibit the deployment permission / prohibition from being changed to ON by a user other than the specific user, or to be changed only by a specific other user, for example, the manager of the specific user. May be permitted.
　これにより、事情を知らない他のユーザによって品番データ群の品質レベルや展開可否の設定内容が変更されることを抑制できる。そうすれば、品質レベルの低い検査項目や検査基準が意図せず検査に用いられてしまうことを抑制できる。 (4) This prevents a user who does not know the circumstances from changing the quality level of the product number data group and the setting contents of whether or not it can be developed. By doing so, it is possible to prevent the inspection items and inspection standards with low quality levels from being used for inspection unintentionally.
＜実施例２＞
　次に、本発明の実施例２について説明する。実施例２においては、既に全ての検査プログラムに信頼性の確認済の品番データ群が適用されている状態で、製造工程において「見逃し」が発生した場合の処理について説明する。図７は、品番データ群における品番レベルがＯＫに設定され、展開可否はＯＮに設定された状態において、検査時に「見逃し」が発生した場合に実行される検査情報管理ルーチン２の処理を示すフローチャートである。本フローは制御端末１のメモリ１０３に記憶されるようにしてもよく、検査装置３から「見逃し」検出のデータが送信された際に、自動的に実行されるようにしてもよい。なお、手動検査が行われるステップについては、検査プログラムは、作業者からの結果入力待ち状態となってもよい。 <Example 2>
Next, a second embodiment of the present invention will be described. In the second embodiment, a description will be given of a process in a case where “missing” occurs in the manufacturing process in a state where the part number data group whose reliability has been confirmed is already applied to all the inspection programs. FIG. 7 is a flowchart showing a process of the inspection information management routine 2 executed when “missing” occurs during inspection in a state where the item number level in the item number data group is set to “OK” and the development possibility is set to “ON”. It is. This flow may be stored in the memory 103 of the control terminal 1, or may be automatically executed when the “missing” detection data is transmitted from the inspection device 3. In addition, regarding the step in which the manual inspection is performed, the inspection program may be in a state of waiting for a result input from an operator.
　本ルーチンが実行されると、まず、ステップＳ２０１において、検査時の「見逃し」が発生したことが検出される。この場合には、不良品が工程で発見されずに通過してしまう危険性があるので緊急の対応が必要になる。よって、ステップＳ２０２において、品番データ群の品質レベルはＮＧに設定される。ステップＳ２０２の処理が終了するとステップＳ２０３に進む。 When this routine is executed, first, in step S201, it is detected that "missing" at the time of inspection has occurred. In this case, there is a risk that the defective product will pass through without being found in the process, so urgent action is required. Therefore, in step S202, the quality level of the product number data group is set to NG. When the process in step S202 ends, the process proceeds to step S203.
　ステップＳ２０３においては、「条件つき一括更新」が行われて、品番データ群が全検査プログラムに適用される。この場合において、「条件付き一括更新」の条件は、展開可否がＯＮであり、品質レベルがＮＧであることに設定されており、全ての検査プログラムにおいて、この条件を満たす中で、最新リビジョンの品番データ群の内容が適用される。そして、この場合には、全検査プログラムにおいて、品質レベルがＮＧの品番データ群が適用されることになる。本実施例における検査システム９では、このような場合には、「見逃し」が発生した品番データ群を参照する検査に関しては、検査プログラムによる自動検査は停止し、手動検査が行われる。その際の表示としては、検査システム９における出力部１０１に表示された品番データ群に係るウィンドウで品番の品質がＮＧと表示されるのみでも良いし、他に何等かのアラート表示がされてもよい。ステップＳ２０３の処理が終了するとステップＳ１０４に進む。 In step S203, "conditional batch update" is performed, and the part number data group is applied to all inspection programs. In this case, the condition of “conditional batch update” is set to “undeployability ON” and “quality level NG”, and in all inspection programs, while satisfying this condition, the latest revision The content of the part number data group is applied. Then, in this case, in all the inspection programs, the part number data group whose quality level is NG is applied. In such a case, the inspection system 9 according to the present embodiment stops the automatic inspection by the inspection program and performs the manual inspection for the inspection referring to the part number data group in which “missing” has occurred. As the display at that time, the quality of the product number may be simply displayed as NG in the window related to the product number data group displayed on the output unit 101 in the inspection system 9 or some other alert display may be performed. Good. When the process in step S203 ends, the process proceeds to step S104.
　ステップＳ１０４～ステップＳ１１４の処理において、図５に示した検査情報管理ルーチンとの相違点は、Ｓ２０６の処理において、ステップＳ１０４で登録した検証画面に対して「見過ぎ」あるいは「見逃し」がなかったか否かが手動検査にて判定される点である。また、ステップＳ２１０において、ステップＳ１０９で行われた検査で「見過ぎ」または「見逃し」が発生したか否かが手動検査で判定される点である。また、ステップＳ２１２においては、ステップＳ１１１の複数の検査において「見過ぎ」または「見逃し」が発生したか否かが手動検査にて判定される点である。なお、Ｓ１１４において、再度「条件付き一括更新」が行われるが、この場合の条件は、展開可否がＯＮであり、品質レベルがＯＫであることに設定されている。 The difference between the processing in steps S104 to S114 and the inspection information management routine shown in FIG. 5 is that in the processing in step S206, there is no "overlooked" or "missed" for the verification screen registered in step S104. Is determined by a manual inspection. Further, in step S210, it is determined whether or not “too much” or “missing” has occurred in the inspection performed in step S109 by a manual inspection. In step S212, it is determined whether or not “overlooking” or “overlooking” has occurred in the plurality of inspections in step S111 by a manual inspection. In step S114, the “conditional batch update” is performed again. In this case, the conditions are set such that the deployment permission is ON and the quality level is OK.
　図８には、上記のように、製造工程において「見過ぎ」が生じた場合に手動検査が行われるようにする、検査システム制御ルーチンについて説明する。本フローは検査プログラム記憶部２３に記憶されるようにしてもよく、検査装置３による検査実施時に実行されるようにしてもよい。本ルーチンが実行されると、まず、ステップＳ３０１において、検査プログラムが読み込まれる。ステップＳ３０１が終了するとステップＳ３０２に進む。ステップＳ３０２においては、ステップＳ３０１で読み込まれた検査プログラムにおいて参照されている品番データ群が読み込まれる。ここで読み込まれる品番データ群は、「条件付き一括更新」において設定された条件を満たす中で、最新のリビジョンに係る品番データ群である。ステップＳ３０２の処理が終了するとステップＳ３０３に進む。ステップＳ３０３においては検査画像が取得される。そして、ステップＳ３０４において検査が実施される。 FIG. 8 illustrates an inspection system control routine for performing a manual inspection when “overseeing” occurs in the manufacturing process as described above. This flow may be stored in the inspection program storage unit 23, or may be executed when the inspection is performed by the inspection device 3. When this routine is executed, first, in step S301, an inspection program is read. When step S301 ends, the process proceeds to step S302. In step S302, a part number data group referred to in the inspection program read in step S301 is read. The part number data group read here is a part number data group relating to the latest revision while satisfying the conditions set in “conditional batch update”. When the process in step S302 ends, the process proceeds to step S303. In step S303, an inspection image is obtained. Then, an inspection is performed in step S304.
　次に、ステップＳ３０５では、品番データ群における品質レベルがＯＫに設定されているか否かが判定される。ここで、品番データ群における品質レベルがＯＫに設定されていれば、ステップＳ３０９に進み自動検査が実施される。一方、ステップＳ３０５において品番データ群における品質レベルがＯＫに設定されていないと判定された場合には、ステップＳ３０６に進む。ステップＳ３０６においては、品番データ群の品質レベルがＴＲＹに設定されているか否かが判定される。ここで、品質レベルがＴＲＹに設定されていると判定された場合には、ステップＳ３０９に進み自動検査が実施される。一方、品質レベルがＴＲＹに設定されていないと判定された場合には、ステップＳ３０７に進む。 Next, in step S305, it is determined whether the quality level in the product number data group is set to OK. Here, if the quality level in the part number data group is set to OK, the process proceeds to step S309, and an automatic inspection is performed. On the other hand, if it is determined in step S305 that the quality level in the product number data group is not set to OK, the process proceeds to step S306. In step S306, it is determined whether or not the quality level of the product number data group is set to TRY. Here, if it is determined that the quality level is set to TRY, the process proceeds to step S309, and an automatic inspection is performed. On the other hand, if it is determined that the quality level is not set to TRY, the process proceeds to step S307.
　ステップＳ３０７においては、品番データ群の品質レベルがＮＧに設定されているか否かが判定される。ここで、品番データ群の品質レベルがＮＧに設定されていると判定された場合には、ステップＳ３０８に進み、手動検査が実施される。一方、品質レベルがＮＧに設定されていないと判定された場合には、ステップＳ３０９に進み、自動検査が実施される。ステップＳ３０９の自動検査または、ステップＳ３０８の手動検査が終了すると、ステップＳ３１０に進む。 In step S307, it is determined whether or not the quality level of the product number data group is set to NG. Here, when it is determined that the quality level of the part number data group is set to NG, the process proceeds to step S308, and a manual inspection is performed. On the other hand, if it is determined that the quality level is not set to NG, the process proceeds to step S309, and an automatic inspection is performed. When the automatic inspection in step S309 or the manual inspection in step S308 ends, the process proceeds to step S310.
　ステップＳ３１０においては検査が終了したか否かが判定される。ステップＳ３１０において検査が終了したと判定された場合には、一旦本ルーチンが終了する。検査が終了していないと判定された場合には、ステップＳ３０４の処理に戻り、検査が継続される。なお、本ルーチンにおいて、品番データ群の品質レベルのデータが、「ＯＫ」、「ＴＲＹ」、「ＮＧ」の３通りしかない場合には、ステップＳ３０６において品番データ群の品質レベルが「ＴＲＹ」ではないと判定された場合に、直接ステップＳ３０８の処理に進んでも構わない。 に お い て In step S310, it is determined whether the inspection has been completed. If it is determined in step S310 that the inspection has been completed, the present routine ends once. If it is determined that the inspection has not been completed, the process returns to step S304, and the inspection is continued. In this routine, if there are only three types of quality level data of the part number data group, “OK”, “TRY”, and “NG”, in step S306, the quality level of the part number data group is “TRY”. If it is determined that there is not, the process may proceed directly to step S308.
　図９は、図７及び図８において説明したように、検査システム９において「見逃し」が発生した場合の、品番参照データテーブルの変更の例について示している。図９（ａ）には、品番ＩＤ００３の部品について、検査プログラム３においてはリビジョン９の品番データ群が参照され、検査プログラム４においては、リビジョン１０の品番データ群が参照されている。そして、リビジョン９、リビジョン１０ともに、品質レベルはＯＫ、展開可否はＯＮに設定されていることが分かる。また、品番ＩＤ００３の部品の品番データ群については、最新リビジョンがリビジョン１２であり、リビジョン１２については品質レベルはＮＧに設定されている。そして、品番展開のステータスは、「要更新」とされていることが分かる。 FIG. 9 shows an example of changing the part number reference data table when “missing” occurs in the inspection system 9 as described in FIGS. 7 and 8. 9A, the part number data group of the revision 9 is referred to in the inspection program 3 and the part number data group of the revision 10 is referred to in the inspection program 3 for the part having the part number ID 003. Then, it can be seen that the quality level is set to OK and the availability of development is set to ON for both revision 9 and revision 10. For the part number data group of the part having the part number ID 003, the latest revision is the revision 12, and the quality level of the revision 12 is set to NG. Then, it can be seen that the status of the part number development is "update required".
　この状態で、いずれかの検査プログラムにおける検査で「見逃し」が発生した場合には、緊急な対応が必要なために、条件を、展開可否ＯＮ且つ、品質レベルＮＧとした上で、品番ＩＤ００３の品番データ群について「条件付き一括更新」が行われる。この場合は、図９（ｂ）に示すように、強制的に品番ＩＤ００３の部品について最新リビジョン１２の品番データが参照される。そして、その品質レベルはＮＧに設定されている。そうすると、図８のステップＳ３０７及びステップＳ３０８に示したとおり、品番ＩＤ００１の部品については、自動検査ではなく手動検査が行われることになる。そして、品番展開のステータスとしては、見逃し対応中と表示される。 In this state, if “missing” occurs in the inspection in any of the inspection programs, an urgent response is required. Therefore, the conditions are set to ON / OFF for development and the quality level is NG. “Conditional batch update” is performed on the part number data group. In this case, as shown in FIG. 9B, the part number data of the latest revision 12 is forcibly referred to for the part having the part number ID 003. Then, the quality level is set to NG. Then, as shown in step S307 and step S308 in FIG. 8, for the part having the part number ID001, not the automatic inspection but the manual inspection is performed. Then, the status of the part number development is displayed as “overlooked”.
　これにより、検査システム９において「見逃し」が発生した場合には、緊急避難的に自動検査を中止し手動検査が行われるようにすることができる。そして、製造工程における検査品質に影響を及ぼすことなく、同時に品番データ群における検査項目や検査基準の最適化を継続することが可能となる。なお、本実施例において、いずれかの検査プログラムにおける検査で「見逃し」が発生した場合には、自動的に品質レベルがＮＧである最新リビジョンの品番データ群が参照されてもよいし、出力部１０１に、品質レベルがＮＧである最新リビジョンの品番データ群を全ての検査プログラムに適用可能な表示をさせ、ユーザが手動で「条件付き一括更新」を行い、品質レベルがＮＧである最新リビジョンの品番データ群に参照させてもよい。なお、上記の適用例及び各実施例においては、品番データ群がリビジョン管理され、検査情報が変更された際には、新たなリビジョンの品番データ群が作成される例について説明した。しかしながら、本発明は、検査情報が変更された際にも、品番データ群が書き換えられるのみで、新たなリビジョンの品番データ群が作成されない場合、すなわち、品番データ群がリビジョン管理されない場合についても適用可能であることは当然である。 Accordingly, when "missing" occurs in the inspection system 9, the automatic inspection can be stopped in an emergency evacuation and the manual inspection can be performed. Then, it is possible to continue optimizing the inspection items and inspection standards in the part number data group without affecting the inspection quality in the manufacturing process. In this embodiment, if “missing” occurs in the inspection in any of the inspection programs, the part number data group of the latest revision whose quality level is NG may be automatically referred to, or the output unit 101, a part number data group of the latest revision whose quality level is NG is displayed so as to be applicable to all inspection programs, and the user manually performs “conditional batch update”, The item number data group may be referred to. In the above-described application examples and embodiments, the example has been described in which the part number data group is revision-managed and a new revision part number data group is created when the inspection information is changed. However, the present invention is also applied to the case where the part number data group is only rewritten when the inspection information is changed and the part number data group of a new revision is not created, that is, the case where the part number data group is not revision-managed. Of course it is possible.
