Description

本発明は、LED素子など同一種類の複数の電子部品を基板に実装する電子部品実装装置に関するものである。   The present invention relates to an electronic component mounting apparatus for mounting a plurality of electronic components of the same type such as LED elements on a substrate.

液晶パネルなどの表示パネルに用いられる照明基板として、LED基板が広く用いられる。このLED基板は、複数のLED素子を基板に所定配列で列状に実装することにより製造され、製造過程においては細長形状の単位基板を複数個結合した矩形の親基板の形態で取り扱われる場合が多い。LED素子を各単位基板に実装する実装過程においては、LED素子は同一種類の多数のLED素子をキャリアテープによって収納保持したテープフィーダから取り出され、単位基板における実装点に順次実装される。   An LED substrate is widely used as an illumination substrate used for a display panel such as a liquid crystal panel. This LED substrate is manufactured by mounting a plurality of LED elements on the substrate in a predetermined arrangement in a row, and may be handled in the form of a rectangular parent substrate in which a plurality of elongated unit substrates are combined in the manufacturing process. Many. In the mounting process of mounting the LED elements on each unit substrate, the LED elements are taken out from a tape feeder in which a large number of LED elements of the same type are stored and held by a carrier tape, and are sequentially mounted at mounting points on the unit substrate.

このとき、照明基板として必要とされる照度分布の均一性を確保するため、同一の単位基板には同一の特性を有する同一生産ロットのLED素子のみを実装することが求められ、たとえ品種的には同一種類であっても生産ロットが異なるものを同一基板に混載することは許されない。このように同一種類であっても品質ランクや生産ロットの異同によって実質的に区別して実装管理を行う必要がある場合の手法として、予め既知の部品個数から実装によって使用された部品数を順次減算して部品残数をカウントしておき、1つのパターンあるいは1つの基板を対象とした実装に必要な部品個数とその時点での部品残数とを比較することによって、実装工程の管理を行う方法が知られている(例えば特許文献1参照)。このような実装管理を行うことにより、1つのパターンや基板には、同一種類の部品であって且つ品質ランクや生産ロットが同一のもののみが実装され、他部品との混載を防止することができる。   At this time, in order to ensure the uniformity of the illuminance distribution required for the illumination substrate, it is required to mount only LED elements of the same production lot having the same characteristics on the same unit substrate, It is not allowed to mix different production lots on the same substrate even if they are of the same type. In this way, even if they are of the same type, it is necessary to distinguish between quality ranks and production lots and implement mounting management, so the number of parts used by mounting is subtracted sequentially from the number of parts already known in advance. The remaining number of components is counted, and the mounting process is managed by comparing the number of components required for mounting on one pattern or one board with the remaining number of components at that time. Is known (see, for example, Patent Document 1). By performing such mounting management, only patterns of the same type and the same quality rank and production lot are mounted on a single pattern or board, preventing mixed loading with other components. it can.

しかしながら上述のような実装管理手法を実際の部品実装ラインに適用するに際しては、以下のような不都合が発生する場合がある。すなわち現実の部品実装過程においては、部品実装動作遂行上の様々な外乱や予測が困難な不測の事態が生じる。例えば、部品実装装置に備えられた部品吸着ノズルの調整状態が良好でないような場合には、部品供給部から部品を取り出す際に吸着不良などに起因するピックアップミスが発生する傾向にある。   However, when the mounting management method as described above is applied to an actual component mounting line, the following inconvenience may occur. That is, in the actual component mounting process, various disturbances in the performance of component mounting operations and unexpected situations that are difficult to predict occur. For example, when the adjustment state of the component suction nozzle provided in the component mounting apparatus is not good, a pickup error due to a suction failure or the like tends to occur when taking out the component from the component supply unit.

そしてこれらのピックアップミスが多発すると、部品残数としては本来十分な数があったにも拘わらず、ピックアップミスによって廃却される部品数が増えて、その結果1つの基板を対象とする部品実装動作中に部品切れを生じる場合がある。また部品実装現場における部品管理は、作業者によるテープリールの交換や部品数の数値入力など人手による作業が多いため、人的ミスが介在することが本質的に避けがたいという問題がある。このため先行技術例にように単に部品残数をカウントするのみでは、同一種類の複数の電子部品を基板に実装する際にロットが異なる部品の混載を完全に防止することが困難であった。   If these pick-up mistakes occur frequently, the number of parts to be discarded due to pick-up mistakes increases despite the fact that there was a sufficient number of remaining parts. Parts may be cut during operation. Also, component management at the component mounting site has a problem that human error is essentially unavoidable because there are many manual operations such as replacement of tape reels and numerical input of the number of components. Therefore, simply counting the remaining number of components as in the prior art example makes it difficult to completely prevent mixed mounting of components of different lots when mounting a plurality of electronic components of the same type on a substrate.

そこで本発明は、同一種類の複数の電子部品を基板に実装する実装形態においてロットが異なる部品の混載を防止することができる電子部品実装装置を提供することを目的とする。   Therefore, an object of the present invention is to provide an electronic component mounting apparatus that can prevent mixed mounting of components of different lots in a mounting form in which a plurality of electronic components of the same type are mounted on a substrate.

First, the overall configuration of the electronic component mounting apparatus 1 will be described with reference to FIG. In FIG. 1, a substrate transport mechanism 2 is disposed in the X direction (substrate transport direction) on the upper surface of a base 1a. The substrate transport mechanism 2 transports the multi-planar substrate 3 to be mounted, and positions and holds the multi-planar substrate 3 on the mounting stage provided at the center position of the substrate transport mechanism 2. Accordingly, the substrate transport mechanism 2 is a substrate holding unit that holds the multi-sided substrate 3.

図3に示すように、多面取り基板3は、細長い冊形状の単位基板3aを幅方向に並列して複数個結合した構成となっており、各単位基板3aには電子部品であるLED素子が実装される実装点3mが単位基板3aの長手方向に直列に設けられている。すなわち電子部品実装装置1は、LED素子など同一種類の電子部品が実装される複数の実装点3mを有する単位基板3aを複数個結合した多面取り基板3を実装作業対象とするものである。この実装作業においては、多面取り基板3の一方側の端部に位置する単位基板3a(1)から、隣接する単位基板3a(2)・・・単位基板3a(N)の順で、各単位基板3aの実装点3mに電子部品が実装される。   As shown in FIG. 3, the multi-planar board 3 has a configuration in which a plurality of elongated book-shaped unit boards 3a are coupled in parallel in the width direction, and each unit board 3a has an LED element as an electronic component. Mounting points 3m to be mounted are provided in series in the longitudinal direction of the unit substrate 3a. In other words, the electronic component mounting apparatus 1 is intended for mounting work on a multi-sided board 3 in which a plurality of unit boards 3a having a plurality of mounting points 3m on which the same kind of electronic components such as LED elements are mounted. In this mounting operation, each unit is arranged in the order of the unit substrate 3a (1) located at one end of the multi-sided substrate 3 to the adjacent unit substrate 3a (2)... Unit substrate 3a (N). An electronic component is mounted on the mounting point 3m of the substrate 3a.

基板搬送機構2の一方の側方には、複数の部品供給部4#1、4#2、4#3が並設されている。これらの部品供給部4#1、4#2、4#3は、いずれも同一品種の複数の電子部品をロット単位で収納したキャリアテープを卷回収納する供給リール4aを備えており、供給リール4aから引き出したキャリアテープをピッチ送りして電子部品を搬送することにより、以下に説明する部品搭載機構への供給位置4bに電子部品を供給する。すなわち、部品供給部4#1、4#2、4#3は、複数個の電子部品をロット単位で収納するとともに、収納した電子部品を所定の供給位置4bへ搬送する機能を備えている。そして、多面取り基板3を対象とした部品実装作業においては、部品供給部4#1、4#2、4#3のうち作業対象として設定された1つの部品供給部4から連続して電子部品が取り出され、当該作業対象の部品供給部4において部品品切れが発生すると、予め設定された供給順序に従って、次の部品供給部4が新たに作業対象として設定される。   On one side of the substrate transport mechanism 2, a plurality of component supply units 4 # 1, 4 # 2, and 4 # 3 are arranged in parallel. Each of these component supply units 4 # 1, 4 # 2, and 4 # 3 includes a supply reel 4a for winding and storing a carrier tape that stores a plurality of electronic components of the same type in units of lots. By feeding the electronic component by pitch-feeding the carrier tape drawn from 4a, the electronic component is supplied to the supply position 4b to the component mounting mechanism described below. That is, the component supply units 4 # 1, 4 # 2, 4 # 3 have a function of storing a plurality of electronic components in units of lots and transporting the stored electronic components to a predetermined supply position 4b. Then, in the component mounting work for the multi-planar board 3, the electronic component is continuously provided from one component supply unit 4 set as a work target among the component supply units 4 # 1, 4 # 2, 4 # 3. Is taken out, and when the component supply unit 4 is out of stock, the next component supply unit 4 is newly set as a work target in accordance with a preset supply sequence.

基台1aの上面においてX方向の両端部にはY軸テーブル5が配設されており、Y軸テーブル5にはX軸テーブル6が架設されている。X軸テーブル6には下面側に複数(ここでは4本)の吸着ノズル8aを備えた搭載ヘッド8がX方向に移動自在に装着されている。Y軸テーブル5、X軸テーブル6を駆動することにより、搭載ヘッド8はX方向、Y方
向へ移動する。これにより、搭載ヘッド8は、部品供給部4#1、4#2、4#3の供給位置4bから電子部品を取り出し、基板搬送機構2に位置決め保持された多面取り基板3へ搭載する。この部品搭載動作における搭載ヘッド8の移動経路には部品認識カメラ9が配置されており、電子部品を吸着ノズル8aによって保持した搭載ヘッド8が部品認識カメラ9の上方を移動することにより、部品認識カメラ9は吸着ノズル8aに保持された状態の電子部品を撮像する。
On the upper surface of the base 1a, Y-axis tables 5 are disposed at both ends in the X direction, and an X-axis table 6 is installed on the Y-axis table 5. A mounting head 8 having a plurality (four in this case) of suction nozzles 8a on the lower surface side is mounted on the X-axis table 6 so as to be movable in the X direction. By driving the Y-axis table 5 and the X-axis table 6, the mounting head 8 moves in the X direction and the Y direction. As a result, the mounting head 8 takes out the electronic components from the supply positions 4b of the component supply units 4 # 1, 4 # 2, and 4 # 3, and mounts them on the multi-sided substrate 3 that is positioned and held by the substrate transport mechanism 2. A component recognition camera 9 is arranged on the movement path of the mounting head 8 in this component mounting operation, and the component recognition camera 9 moves when the mounting head 8 holding the electronic component by the suction nozzle 8a moves above the component recognition camera 9. The camera 9 images the electronic component held by the suction nozzle 8a.

上記構成において、Y軸テーブル5およびX軸テーブル6は、搭載ヘッド8を移動させる搭載ヘッド移動機構7を構成し、さらに搭載ヘッド移動機構7および搭載ヘッド8は、供給位置4bへ搬送された電子部品を吸着ノズル8aで取出して、基板保持部である基板搬送機構2に位置決めされた多面取り基板3へ搭載する部品搭載機構を構成する。基台1a上には、タッチパネルを組み込んだ操作パネル10が配置されており、パネル上に各種の画面表示を行うとともに、パネルをタッチ操作することにより、操作指示やデータ入力が同一画面上で可能となっている。   In the above configuration, the Y-axis table 5 and the X-axis table 6 constitute a mounting head moving mechanism 7 that moves the mounting head 8, and the mounting head moving mechanism 7 and the mounting head 8 are further transferred to the supply position 4b. A component mounting mechanism is configured in which the components are picked up by the suction nozzle 8a and mounted on the multi-sided substrate 3 positioned by the substrate transport mechanism 2 which is a substrate holding unit. An operation panel 10 incorporating a touch panel is arranged on the base 1a, and various screen displays are performed on the panel, and operation instructions and data input can be performed on the same screen by touching the panel. It has become.

基台1aの内部には、制御部11が内蔵されている。図2に示すように、制御部11は、部品認識部12、部品供給部4#1、4#2、4#3、搭載ヘッド移動機構7、搭載ヘッド8、表示部13、操作・入力部14と接続されている。部品認識部12は部品認識カメラ9による撮像結果を認識処理することにより搭載ヘッド8に保持された電子部品を認識し、認識結果を制御部11に送る。制御部11が部品供給部4#1、4#2、4#3を制御することにより、それぞれの部品供給部4#1、4#2、4#3に収納された電子部品は、部品搭載機構への供給位置4bに搬送される。   A control unit 11 is built in the base 1a. As shown in FIG. 2, the control unit 11 includes a component recognition unit 12, a component supply unit 4 # 1, 4 # 2, 4 # 3, a mounting head moving mechanism 7, a mounting head 8, a display unit 13, and an operation / input unit. 14. The component recognition unit 12 recognizes the electronic component held by the mounting head 8 by performing recognition processing on the imaging result obtained by the component recognition camera 9, and sends the recognition result to the control unit 11. When the control unit 11 controls the component supply units 4 # 1, 4 # 2, 4 # 3, the electronic components stored in the respective component supply units 4 # 1, 4 # 2, 4 # 3 are mounted on the components. It is conveyed to the supply position 4b to the mechanism.

また制御部11が搭載ヘッド移動機構7、搭載ヘッド8を制御することにより、作業対象に設定された部品供給部4から供給される同一種類の電子部品を、実装対象の単位基板3aの全ての実装点3mに順次実装する単位基板実装作業が実行される。さらにこの単位基板実装作業は、多面取り基板3を構成する全ての単位基板3aを対象として連続して実行される。また4本の吸着ノズル8aを備えた搭載ヘッド8には、各吸着ノズル8aに対応してそれぞれ圧力センサ8b(1)(2)(3)(4)が設けられており、吸着ノズル8aによって真空吸着により電子部品をピックアップした後に、圧力センサ8bによって真空吸引経路の圧力を検出する。   Further, the control unit 11 controls the mounting head moving mechanism 7 and the mounting head 8, so that the same type of electronic components supplied from the component supply unit 4 set as a work target can be all of the unit substrates 3 a to be mounted. Unit board mounting work for sequentially mounting on the mounting point 3m is executed. Further, this unit board mounting operation is continuously executed for all the unit boards 3a constituting the multi-sided board 3. The mounting head 8 having four suction nozzles 8a is provided with pressure sensors 8b (1) (2) (3) (4) corresponding to the respective suction nozzles 8a. After picking up the electronic component by vacuum suction, the pressure of the vacuum suction path is detected by the pressure sensor 8b.

すなわち制御部11は、部品供給部4#1、4#2、4#3における電子部品の搬送動作と部品搭載機構による電子部品の搭載動作とを制御することにより、作業対象に設定された部品供給部4から供給される同一種類の電子部品を一の単位基板3aの全ての実装点3mに搭載する単位基板実装作業を、多面取り基板3内の複数の単位基板3aに対して連続して実行する機能を有している。   That is, the control unit 11 controls the electronic component transport operation in the component supply units 4 # 1, 4 # 2, 4 # 3 and the electronic component mounting operation by the component mounting mechanism, thereby setting the component set as the work target. A unit board mounting operation for mounting the same type of electronic components supplied from the supply unit 4 to all mounting points 3m of one unit board 3a is continuously performed on a plurality of unit boards 3a in the multi-sided board 3. Has the function to execute.

表示部13、操作・入力部14は、操作パネル10に組み込まれたタッチパネルである。表示部13は、制御部11によって制御されて操作パネル10のパネル上に、部品供給部4における部品品切れの報知などの各種の画面表示を行う。またパネルをタッチ操作することにより、操作・入力部14によって制御部11に対して操作指示やデータ入力が行われる。この操作指示には、部品品切れ発生時において作業者による電子部品の補給作業が完了した旨の入力操作が含まれる。   The display unit 13 and the operation / input unit 14 are touch panels incorporated in the operation panel 10. The display unit 13 is controlled by the control unit 11 to display various screens such as notification of component out of stock in the component supply unit 4 on the panel of the operation panel 10. Also, by operating the touch panel, the operation / input unit 14 gives an operation instruction or data input to the control unit 11. This operation instruction includes an input operation to the effect that the operator has completed the replenishment operation of the electronic component when the component is out of stock.

制御部11の構成および機能を説明する。制御部11は、搭載動作処理部20、ピックアップミス検出部21、部品品切れ検出部22、部品残数更新部23、部品残数比較部24、ロット切換処理部25、動作モード設定部26および記憶部30を備えている。記憶部30はさらに実装済部品数記憶部31、基板情報記憶部32、単位基板実装点データ記憶部33、閾値データ記憶部34、作業対象記憶部35、部品残数記憶部36より構成さ
れる。
The configuration and function of the control unit 11 will be described. The control unit 11 includes a mounting operation processing unit 20, a pickup miss detection unit 21, a component out-of-stock detection unit 22, a remaining component number update unit 23, a remaining component number comparison unit 24, a lot switching processing unit 25, an operation mode setting unit 26, and a storage. The unit 30 is provided. The storage unit 30 further includes a mounted component number storage unit 31, a board information storage unit 32, a unit board mounting point data storage unit 33, a threshold data storage unit 34, a work target storage unit 35, and a component remaining number storage unit 36. .

搭載動作処理部20は、部品供給部4#1、4#2、4#3および搭載ヘッド移動機構7、搭載ヘッド8より成る部品搭載機構を制御することにより、電子部品を多面取り基板3に実装するための搭載動作を実行させる処理を行う。ピックアップミス検出部21は、搭載ヘッド8に設けられた圧力センサ8b(1)(2)(3)(4)による真空吸引経路の圧力検出結果に基づいて、吸着ノズル8aが電子部品を正常にピックアップできないピックアップミスが発生したか否かを検出する。部品品切れ検出部22は、部品供給部4#1、4#2、4#3のいずれかを対象とした部品取り出し動作において、ピックアップミス検出部21によってピックアップミスが所定回数連続して検出されたならば、当該部品供給部4において部品品切れが発生したと判断する。すなわち、部品品切れ検出部22は、吸着ノズル8aによる部品供給部4からの電子部品の取出しが所定回数連続して失敗したことを以て、当該部品供給部4における電子部品の品切れを検出する処理を行う。   The mounting operation processing unit 20 controls the component mounting mechanism including the component supply units 4 # 1, 4 # 2, 4 # 3, the mounting head moving mechanism 7, and the mounting head 8, so that the electronic component is transferred to the multi-sided substrate 3. A process for executing the mounting operation for mounting is performed. Based on the pressure detection result of the vacuum suction path by the pressure sensor 8b (1) (2) (3) (4) provided in the mounting head 8, the pickup miss detection unit 21 causes the suction nozzle 8a to properly operate the electronic component. It detects whether or not a pickup error that cannot be picked up has occurred. The component out-of-stock detection unit 22 detects pickup mistakes continuously for a predetermined number of times by the pickup error detection unit 21 in the component take-out operation targeting any one of the component supply units 4 # 1, 4 # 2, and 4 # 3. If so, it is determined that the component supply unit 4 has run out of components. That is, the component out-of-stock detection unit 22 performs a process of detecting an out-of-stock of electronic components in the component supply unit 4 when the removal of the electronic component from the component supply unit 4 by the suction nozzle 8a has failed for a predetermined number of times. .

部品残数更新部23は、部品供給部4#1、4#2、4#3における部品搬送動作の回数に応じて、部品残数を減算することにより、部品残数記憶部36に記憶された部品供給部4#1、4#2、4#3における実際の部品残数を逐次更新する。部品残数比較部24は、単位基板実装作業を開始する前に、部品残数記憶部36に記憶された3つの部品供給部4#1、4#2、4#3の部品残数のうち、作業対象に設定された部品供給部4の部品残数と、閾値データ記憶部34に記憶された閾値とを比較して、部品残数が閾値未満であるか否かを判定する処理を行う。   The remaining component number update unit 23 stores the remaining component number in the remaining component number storage unit 36 by subtracting the remaining component number according to the number of component conveying operations in the component supply units 4 # 1, 4 # 2, and 4 # 3. The actual component remaining numbers in the component supply units 4 # 1, 4 # 2, and 4 # 3 are sequentially updated. The component remaining number comparison unit 24, among the remaining component numbers of the three component supply units 4 # 1, 4 # 2, and 4 # 3, stored in the component remaining number storage unit 36 before starting the unit board mounting operation. The number of remaining parts of the component supply unit 4 set as a work target is compared with the threshold stored in the threshold data storage unit 34 to determine whether the remaining number of parts is less than the threshold. .

ロット切換処理部25は、ロット切換処理、すなわち、搭載ヘッド8による電子部品の取出し作業の作業対象となる部品供給部4を変更するための処理、および部品供給部4の変更に伴って必要とされる各種の処理を実行する。これらの処理には、部品品切れ検出部22が1つの単位基板3aを対象とする単位基板実装作業の途中で部品品切れを検出した場合に、実行中の単位基板実装作業を中止して実装点データ上で設定されていた実装点をキャンセルする実装点キャンセル処理、部品残数比較部24による部品残数比較の結果に基づいて作業対象となる部品供給部4を変更する処理、作業対象として設定された部品供給部4を特定するための情報を変更して作業対象記憶部35に記憶させる処理、実装対象を次の単位基板3aに移行する処理などが含まれる。   The lot switching processing unit 25 is necessary in accordance with the lot switching processing, that is, the processing for changing the component supply unit 4 that is the work target of the electronic component take-out operation by the mounting head 8 and the change of the component supply unit 4. Various processes are executed. In these processes, when the component out of stock detection unit 22 detects out of component parts in the middle of the unit substrate mounting operation for one unit substrate 3a, the unit substrate mounting operation being executed is stopped and the mounting point data is displayed. Mounting point cancellation processing for canceling the mounting points set above, processing for changing the component supply unit 4 to be a work target based on the result of component remaining number comparison by the component remaining number comparison unit 24, and setting as a work target The process for changing the information for specifying the component supply unit 4 to be stored in the work target storage unit 35, the process for transferring the mounting target to the next unit board 3a, and the like are included.

このような作業対象となる部品供給部4の変更に伴う処理は、ロットの異なる電子部品が同一の単位基板3aに混載されることを防止することを目的として実行される。すなわち複数のLED素子を単位基板に実装して照明基板を製造する場合などには、同一の単位基板には同一の特性を有する同一ロットの電子部品のみを実装することが求められる。本実施の形態の示す電子部品実装装置1においては、ロット切換処理部25に上述の各処理を実行させることにより、この目的を達成するようにしている。なおロット切換処理部25の詳細機能については、後述する動作例の説明において、動作フローおよび図面に即して詳述する。   The process accompanying the change of the component supply unit 4 as the work target is executed for the purpose of preventing electronic components of different lots from being mixedly mounted on the same unit substrate 3a. That is, when a lighting board is manufactured by mounting a plurality of LED elements on a unit board, it is required to mount only the same lot of electronic components having the same characteristics on the same unit board. In the electronic component mounting apparatus 1 shown in the present embodiment, this object is achieved by causing the lot switching processing unit 25 to execute the above-described processes. The detailed function of the lot switching processing unit 25 will be described in detail in the description of the operation example described later in accordance with the operation flow and the drawings.

動作モード設定部26は、オペレータの操作入力によって指示される電子部品実装装置1の動作モードを設定する。後述するように、本実施の形態に示す電子部品実装装置1においては、各部品供給部4における部品残数の管理を行わずに、実際の実装作業における部品品切れの検出結果に基づいて単位基板実装作業を管理する動作モード1と、部品品切れの検出とともに各部品供給部4における部品残数を常に監視することによって単位基板実装作業を管理する動作モード2とを使い分けることができるようになっている。   The operation mode setting unit 26 sets the operation mode of the electronic component mounting apparatus 1 that is instructed by an operation input by the operator. As will be described later, in the electronic component mounting apparatus 1 shown in the present embodiment, the unit substrate is based on the detection result of the out of component in the actual mounting operation without managing the remaining number of components in each component supply unit 4. The operation mode 1 for managing the mounting work and the operation mode 2 for managing the unit board mounting work can be properly used by constantly monitoring the remaining number of parts in each of the component supply units 4 together with the detection of out of parts. Yes.

記憶部30の記憶内容について説明する。実装済部品数記憶部31は、各単位基板3aに実際に搭載された部品数を記憶する。すなわち、部品供給部4からの取り出し時にピッ
クアップミスが生じた場合や、一旦取り出されても動作ミスにより搭載されなかった場合は、実装済みの部品数としてカウントされない。実装済部品数記憶部31への書き込みは搭載動作処理部20によって行われ、実装対象が1つの単位基板3aから次の単位基板3aへ切換わると、部品数はクリアされる。
The contents stored in the storage unit 30 will be described. The mounted component number storage unit 31 stores the number of components actually mounted on each unit substrate 3a. That is, when a pickup mistake occurs when taking out from the component supply unit 4, or when it is once taken out and not mounted due to an operation mistake, it is not counted as the number of mounted components. Writing to the mounted component number storage unit 31 is performed by the mounting operation processing unit 20, and the number of components is cleared when the mounting target is switched from one unit substrate 3a to the next unit substrate 3a.

基板情報記憶部32は、基板情報、すなわち対象となる多面取り基板3における単位基板3aの数量や配置についてのデータを記憶する。単位基板実装点データ記憶部33は、1つの単位基板3aにおける実装点3mの相対座標データを記憶する。そして搭載動作処理部20が、単位基板実装作業の都度基板情報記憶部32から読み取った基板情報と単位基板実装点データ記憶部33から読み取った相対座標データとを組み合わせることにより、基板搬送機構2に位置決め保持された多面取り基板3に対して電子部品を搭載する際の実装座標を示す実装点データが作成され、搭載動作処理部20にロードされる。   The board information storage unit 32 stores board information, that is, data on the number and arrangement of the unit boards 3a in the target multi-planar board 3. The unit board mounting point data storage unit 33 stores relative coordinate data of the mounting point 3m on one unit board 3a. Then, the mounting operation processing unit 20 combines the board information read from the board information storage unit 32 and the relative coordinate data read from the unit board mounting point data storage unit 33 each time the unit board mounting operation is performed. Mounting point data indicating mounting coordinates when electronic components are mounted on the multi-sided substrate 3 that is positioned and held is created and loaded into the mounting operation processing unit 20.

図4を参照して、実装点データ[3a(N)]、すなわち図3に示すN番目の単位基板3aについて作成される実装点データについて説明する。実装点データ[3a(N)]は、当該単位基板3aにおける複数の実装点3mを個別に特定するための実装点番号[3m]、各実装点3mの多面取り基板3における位置座標を示す座標データ[X,Y]、各実装点3mについて、実際に部品搭載が実行されたか否かを示す搭載フラグ[FL(M)]、各実装点3mについて実装点キャンセル処理が行われたか否かを示すキャンセルフラグ[FL(C)]より構成される。搭載フラグ[FL(M)]にて1が書き込まれた実装点3mは実装済みであることを示し、0が書き込まれた実装点3mは未実装であることを示す。キャンセルフラグ[FL(C)]にて1が書き込まれた実装点3mは実装がキャンセルされたことを示し、0が書き込まれた実装点3mはデフォルト状態であって通常通り実装が行われることを示す。   With reference to FIG. 4, the mounting point data [3a (N)], that is, the mounting point data created for the Nth unit substrate 3a shown in FIG. 3 will be described. The mounting point data [3a (N)] is a mounting point number [3m] for individually specifying a plurality of mounting points 3m on the unit substrate 3a, and coordinates indicating the position coordinates of the mounting points 3m on the multi-sided substrate 3 Data [X, Y], mounting flag [FL (M)] indicating whether or not component mounting has actually been executed for each mounting point 3m, and whether or not mounting point cancellation processing has been performed for each mounting point 3m The cancel flag [FL (C)] shown in FIG. The mounting point 3m in which 1 is written in the mounting flag [FL (M)] indicates that the mounting is completed, and the mounting point 3m in which 0 is written indicates that it is not mounted. The mounting point 3m in which 1 is written in the cancel flag [FL (C)] indicates that the mounting has been canceled, and the mounting point 3m in which 0 is written is in the default state and indicates that the mounting is performed normally. Show.

閾値データ記憶部34は、単位基板3aにおける実装点3mの個数に余裕値を加えた値を、閾値として記憶する。この閾値は、作業対象として設定されている部品供給部4に、実装対象となる単位基板3aの実装点3mの全てに実装するのに十分な部品残数が確保されているか否かを判定するために用いられるものである。ここでは、実装点3mの個数に加えて、部品搭載動作の途中で発生する可能性のあるピックアップミスや部品認識カメラ9による部品認識NGなどの理由によって、実際に搭載されずに廃棄される電子部品の数を予め想定して余裕値として加算した数を閾値として用いるようにしている。   The threshold data storage unit 34 stores a value obtained by adding a margin value to the number of mounting points 3m on the unit substrate 3a as a threshold. This threshold value determines whether or not the component supply unit 4 set as a work target has a sufficient number of remaining components to be mounted on all the mounting points 3m of the unit substrate 3a to be mounted. It is used for this purpose. Here, in addition to the number of mounting points 3m, electronic components that are discarded without being actually mounted due to reasons such as pickup mistakes that may occur during the component mounting operation or component recognition NG by the component recognition camera 9 The number added as a margin value assuming the number of parts in advance is used as the threshold value.

作業対象記憶部35は、作業対象として設定されている部品供給部4を特定するための情報を記憶する。この情報はロット切換処理部25によって変更され、搭載動作処理部20は作業対象記憶部35に記憶された情報にしたがって作業対象の部品供給部4を特定して部品取り出し動作を実行する。部品残数記憶部36は、部品供給部4#1、4#2、4#3のそれぞれについて、部品残数S1,S2,S3を記憶する。部品残数S1,S2,S3は、部品残数更新部23によって逐次更新される。   The work target storage unit 35 stores information for specifying the component supply unit 4 set as a work target. This information is changed by the lot switching processing unit 25, and the mounting operation processing unit 20 specifies the work target component supply unit 4 according to the information stored in the work target storage unit 35, and executes the component picking operation. The remaining component number storage unit 36 stores the remaining component numbers S1, S2, and S3 for each of the component supply units 4 # 1, 4 # 2, and 4 # 3. The remaining component numbers S1, S2, S3 are sequentially updated by the remaining component number updating unit 23.

次に図5を参照して、動作モード1,すなわち各部品供給部4における部品残数の管理を行わずに、実際の実装作業における部品品切れの検出結果に基づいて単位基板実装作業を管理する動作モードの実際例について説明する。まず、多面取り基板3において、当該単位基板実装作業において実装対象となる単位基板3aを特定するカウンタをリセットする(ST1)。ここではまず最初に、カウンタ値Nを1にセットする。次いで、N番目(最初の場合は1番目)の単位基板3a(N)の実装点データ[3a(N)]を搭載動作処理部20にロードする(ST2)。   Next, referring to FIG. 5, the unit board mounting operation is managed based on the detection result of the out of component in the actual mounting operation without managing the remaining number of components in the operation mode 1, that is, each component supply unit 4. An actual example of the operation mode will be described. First, in the multi-sided board 3, a counter for specifying the unit board 3a to be mounted in the unit board mounting work is reset (ST1). Here, first, the counter value N is set to 1. Next, the mounting point data [3a (N)] of the Nth (first in the first case) unit substrate 3a (N) is loaded into the mounting operation processing unit 20 (ST2).

この後、当該単位基板3aを対象として、単位基板実装作業が開始される(ST3)。すなわち、その時点において作業対象となっている部品供給部4から部品搭載機構によっ
て電子部品を取り出して、当該単位基板3aの各実装点3mへ順次搭載する部品搭載動作を反復して実行する。この部品搭載動作の過程においては、部品品切れ検出部22によって部品切れ発生の有無を常に監視する(ST4)。すなわち、吸着ノズル8aによる部品供給部4からの電子部品の取り出しが所定回数連続して失敗したことを以て、当該部品供給部4における電子部品の品切れを検出する(部品品切れ検出工程)。ここで部品切れ発生なしであれば、当該単位基板実装作業を終了したか否かを判断する(ST5)。すなわち、実装済部品数記憶部31に記憶された実装済部品数が規定数に到達したか否かを判断し、実装済部品数が規定数に満たない場合にはさらに部品搭載動作を反復する。
Thereafter, the unit substrate mounting operation is started for the unit substrate 3a (ST3). That is, an electronic component is taken out from the component supply unit 4 which is a work target at that time by the component mounting mechanism, and the component mounting operation of sequentially mounting the electronic component on each mounting point 3m of the unit substrate 3a is repeatedly executed. In the process of the component mounting operation, the component out-of-stock detection unit 22 always monitors whether or not a component is out of production (ST4). That is, out of the electronic component in the component supply unit 4 is detected when the removal of the electronic component from the component supply unit 4 by the suction nozzle 8a has failed continuously a predetermined number of times (component out-of-stock detection step). Here, if there is no occurrence of component breakage, it is determined whether or not the unit board mounting operation is completed (ST5). That is, it is determined whether or not the number of mounted components stored in the mounted component number storage unit 31 has reached a specified number. If the number of mounted components is less than the specified number, the component mounting operation is further repeated. .

そして(ST5)にて実装済部品数が規定数に到達したことが確認されたならば、当該単位基板3aを対象とする単位基板実装作業を終了する(ST6)。次いで、次の実装対象となる単位基板の有無を判断し(ST12)、無しの場合には多面取り基板3を対象とする実装作業を終了する。そして有りの場合には、カウンタ値NをN+1に歩進させて(ST13)、(ST2)に戻って次の単位基板3aの実装点データをロードして、同様の単位基板実装作業を反復実行する。   If it is confirmed in (ST5) that the number of mounted parts has reached the specified number, the unit board mounting operation for the unit board 3a is terminated (ST6). Next, the presence / absence of a unit substrate to be mounted next is determined (ST12), and when there is no unit substrate, the mounting operation for the multi-chip board 3 is ended. If yes, the counter value N is incremented to N + 1 (ST13), the process returns to (ST2), the mounting point data of the next unit board 3a is loaded, and the same unit board mounting operation is repeatedly executed. To do.

これに対し、(ST4)にて部品品切れ検出部22によって部品切れ発生が検出された場合には、以下の処理が実行される。まず、実行中の単位基板実装作業を中止する(ST7)。次いで、実装済部品数が0であるか否かを実装済部品数記憶部31に記憶された実装済部品数を参照することにより判断する(ST8)。図6は、同一ロットに属する電子部品P1が単位基板3a(1)から順次実装され、単位基板3a(6)に6個の電子部品P1を実装した時点で部品品切れが発生した例を示している。   On the other hand, when the out-of-component occurrence is detected by the out-of-component detection unit 22 in (ST4), the following processing is executed. First, the unit board mounting operation being executed is stopped (ST7). Next, whether or not the number of mounted components is 0 is determined by referring to the number of mounted components stored in the mounted component number storage unit 31 (ST8). FIG. 6 shows an example in which the component parts are out of stock when the electronic components P1 belonging to the same lot are sequentially mounted from the unit substrate 3a (1) and six electronic components P1 are mounted on the unit substrate 3a (6). Yes.

この例のように実装済部品数が0ではなく、既に幾つかの電子部品が実装されている場合には、実装点キャンセル処理を行う(ST9)。すなわち、ロット切換処理部25によって実装点キャンセル処理を行うことにより、単位基板3a(6)について作成される実装点データ[3a(6)]は、図7に示す内容に変更される。まず搭載フラグ[FL(M)]は、部品品切れが発生した7番目以降の実装点3mについては、未実装であることを示す0が書き込まれ、キャンセルフラグ[FL(C)]については、実装がキャンセルされたことを示す1が書き込まれる。   When the number of mounted components is not 0 as in this example and some electronic components are already mounted, a mounting point canceling process is performed (ST9). That is, by performing the mounting point canceling process by the lot switching processing unit 25, the mounting point data [3a (6)] created for the unit board 3a (6) is changed to the contents shown in FIG. First, in the mounting flag [FL (M)], 0 indicating that the component is not mounted is written in the seventh and subsequent mounting points 3m where the component has run out, and the mounting flag [FL (C)] is mounted in the mounting flag [FL (M)]. 1 is written indicating that is canceled.

次いで、ロット切換処理がロット切換処理部25によって実行される(ST10)。すなわち、作業対象となる部品供給部4を、当該時点で設定されていて部品品切れが発生した部品供給部4から、予め次の作業対象として供給順序が設定された他の部品供給部4に変更する処理を行う。そしてこの後、(ST12)に進み、次の単位基板3aの有無を確認しながら、単位基板3a(7)以降の各単位基板3aを対象として単位基板実装作業が実行される。すなわち、新たに作業対象に設定された部品供給部4から、同一ロットに属する電子部品P2が連続的に取り出され、各単位基板3aに順次実装される。この場合には、実装点キャンセルの対象となった単位基板3a(6)は、作業未完のまま実装が中止され、不良基板として廃棄の対象となる。   Next, lot switching processing is executed by the lot switching processing unit 25 (ST10). In other words, the component supply unit 4 that is the work target is changed from the component supply unit 4 that is set at that time and the component is out of stock to another component supply unit 4 that is set in advance as the next work target. Perform the process. Thereafter, the process proceeds to (ST12), and unit substrate mounting work is executed for each unit substrate 3a after the unit substrate 3a (7) while confirming the presence or absence of the next unit substrate 3a. That is, electronic components P2 belonging to the same lot are continuously taken out from the component supply unit 4 newly set as a work target, and sequentially mounted on each unit substrate 3a. In this case, the mounting of the unit board 3a (6) subject to the mounting point cancellation is stopped while the operation is not completed, and is discarded as a defective board.

すなわち上記処理においては、ロット切換処理部25は、部品品切れ検出工程において、部品品切れ検出部22が単位基板3a(6)(一の単位基板)を対象とする単位基板実装作業の途中で部品品切れを検出したならば、当該単位基板3a(6)を対象とする単位基板実装作業を中止して単位基板3a(7)(次の単位基板)を対象とする単位基板実装作業に移行するとともに、作業対象となる部品供給部4を当該時点で設定されている部品供給部4から他の部品供給部4に変更する(ロット切換処理工程)。   That is, in the above process, the lot switching processing unit 25 is in the process of detecting a component out of stock, and the component out of stock detection unit 22 runs out of a component in the middle of a unit substrate mounting operation for the unit substrate 3a (6) (one unit substrate). Is detected, the unit board mounting work for the unit board 3a (6) is stopped, and the unit board mounting work for the unit board 3a (7) (next unit board) is transferred to. The component supply unit 4 to be worked is changed from the component supply unit 4 set at that time to another component supply unit 4 (lot switching process step).

また(ST8)にて、実装済部品数が0の場合、すなわち図8に示す例のように、単位基板3a(1)から単位基板3a(6)までを対象とした電子部品P1の実装が完了し、
単位基板3a(7)の最初の実装点3mを対象とした時点で部品品切れが発生したような場合には、実装点キャンセル処理を行う必要がない。この場合には、そのままロット切換処理がロット切換処理部25によって実行される(ST11)、すなわち、作業対象となる部品供給部4を、当該時点で設定されていて部品品切れが発生した部品供給部4から他の部品供給部4に変更する処理を行い、単位基板3a(7)を対象として(ST3)に戻って単位基板実装動作が開始される。
In (ST8), when the number of mounted parts is 0, that is, as in the example shown in FIG. 8, the mounting of the electronic component P1 from the unit board 3a (1) to the unit board 3a (6) is performed. Completed,
In the case where a component is sold out at the time when the first mounting point 3m of the unit substrate 3a (7) is targeted, there is no need to perform the mounting point canceling process. In this case, the lot switching processing is executed as it is by the lot switching processing unit 25 (ST11), that is, the component supply unit 4 that has been set as the work target and the component has run out has been generated. The process of changing from 4 to another component supply unit 4 is performed, and the unit board mounting operation is started by returning to (ST3) for the unit board 3a (7).

これにより、単位基板3a(7)以降の各単位基板3aを対象として、新たに作業対象に設定された部品供給部4から同一ロットに属する電子部品P2が連続的に取り出され、各単位基板3aに順次実装される。すなわちこの場合は、ロット切換処理部25は、部品品切れ検出部22が単位基板3a(7)(一の単位基板)への単位基板実装作業の開始時に部品品切れを検出した場合は、作業対象となる部品供給部4を当該時点で設定されている部品供給部4から他の部品供給部4に変更し、その後次の単位基板3aへの単位基板実装作業へ移行することなく、単位基板3a(7)への単位基板実装作業を始めから実行する。   As a result, for each unit substrate 3a after the unit substrate 3a (7), electronic components P2 belonging to the same lot are continuously taken out from the component supply unit 4 newly set as a work target, and each unit substrate 3a. Will be implemented sequentially. In other words, in this case, the lot switching processing unit 25 determines that the component out of stock detection unit 22 detects that the component is out of stock at the start of the unit substrate mounting work on the unit substrate 3a (7) (one unit substrate). The component supply unit 4 is changed from the component supply unit 4 set at that time to another component supply unit 4, and then the unit substrate 3a ( The unit board mounting operation to 7) is executed from the beginning.

次に図9を参照して、動作モード2,すなわち部品品切れの検出とともに各部品供給部4における部品残数を常に監視することによって単位基板実装作業を管理する動作モード2の実際例について説明する。まず、多面取り基板3において、当該単位基板実装作業において実装対象となる単位基板3aを特定するカウンタをリセットする(ST11)。ここではまず最初に、カウンタ値Nを1にセットする。次いで、N番目(最初の場合は1番目)の単位基板3a(N)の実装点データ[3a(N)]を搭載動作処理部20にロードする(ST12)。   Next, referring to FIG. 9, an actual example of the operation mode 2, that is, the operation mode 2 in which the unit board mounting work is managed by constantly monitoring the number of remaining components in each component supply unit 4 together with the detection of component out of stock will be described. . First, in the multi-sided board 3, a counter for specifying the unit board 3a to be mounted in the unit board mounting work is reset (ST11). Here, first, the counter value N is set to 1. Next, the mounting point data [3a (N)] of the Nth (first in the first case) unit substrate 3a (N) is loaded into the mounting operation processing unit 20 (ST12).

この後、ロット切換処理部25により当該時点において作業対象となっている部品供給部4の部品残数が単位基板3aについて設定されている閾値以上であるか否かを判断する(ST13)。ここで、部品残数が閾値未満であれば、当該単位基板3aについて部品不足により部品品切れが発生する可能性有りと判断して、ロット切換処理を実行する(ST14)。すなわち、作業対象となる部品供給部4を、当該時点で設定されていて部品品切れの発生の可能性のある部品供給部4から他の部品供給部4に変更する処理を行い、(ST13)に戻って、変更された部品供給部4について同様に部品残数比較処理を実行する。   Thereafter, the lot switching processing unit 25 determines whether or not the remaining number of components of the component supply unit 4 that is the work target at the time is equal to or greater than a threshold set for the unit substrate 3a (ST13). Here, if the number of remaining parts is less than the threshold, it is determined that there is a possibility that the unit board 3a may be out of parts due to a shortage of parts, and lot switching processing is executed (ST14). That is, the processing is performed to change the component supply unit 4 to be a work target from the component supply unit 4 that is set at the time point and has the possibility of out of component parts to another component supply unit 4 (ST13). Returning, the remaining component number comparison process is similarly executed for the changed component supply unit 4.

そして(ST13)にて部品残数が閾値以上であれば当該単位基板3aについては部品品切れが生じないと判断して、当該単位基板3aを対象として単位基板実装作業が開始される(ST15)。これ以降に実行される(ST15)〜(ST25)は、図5に示す動作モード1における(ST3)〜(ST13)と同様である。ただし、動作モード2においては、(ST23)のロット切換処理の後、再度(ST13)に戻って、変更後の部品供給部4について同様に部品残数比較処理を実行する。   If the number of remaining components is equal to or greater than the threshold value in (ST13), it is determined that the component board 3a is not out of stock, and unit board mounting work is started for the unit board 3a (ST15). Subsequent steps (ST15) to (ST25) are the same as (ST3) to (ST13) in the operation mode 1 shown in FIG. However, in the operation mode 2, after the lot switching process in (ST23), the process returns to (ST13) again, and the remaining part number comparison process is similarly executed for the changed part supply unit 4.

この動作モード2の具体例について、図10を参照して説明する。ここでは、同一ロットに属する電子部品P1が単位基板3a(1)から順次実装され、単位基板3a(5)への実装を完了した時点で、作業対象となっている部品供給部4の部品残数が閾値未満となった場合を示している。すなわちこの場合には、単位基板3a(6)を対象とする単位基板実装作業を開始する前に実行される部品残数比較処理(ST13)において、部品残数が閾値未満であると判定され、その結果ロット切換処理(ST14)が実行される。   A specific example of the operation mode 2 will be described with reference to FIG. Here, the electronic components P1 belonging to the same lot are sequentially mounted from the unit substrate 3a (1), and when the mounting on the unit substrate 3a (5) is completed, the remaining component of the component supply unit 4 that is the work target is left. The case where the number becomes less than the threshold is shown. That is, in this case, in the component remaining number comparison process (ST13) executed before starting the unit substrate mounting operation for the unit substrate 3a (6), it is determined that the component remaining number is less than the threshold value. As a result, lot switching processing (ST14) is executed.

これにより、作業対象となる部品供給部4が、当該時点で設定されていて部品品切れの発生の可能性のある部品供給部4から予め次の作業対象として供給順序が設定された他の部品供給部4に変更される。そしてこれ以降(ST15)〜(ST25)の各処理が実行
され、変更された部品供給部4から取り出された電子部品P2が単位基板3a(6)以下の単位基板3aに順次実装される。すなわちこの場合には、ロット切換処理部25は、部品残数が閾値未満(または閾値以下)であれば、作業対象となる部品供給部4を当該時点で設定されている部品供給部4から他の部品供給部4に変更する処理を行う。
As a result, the component supply unit 4 that is the target of work is supplied from the component supply unit 4 that has been set at that time and is likely to run out of components, and the other parts are supplied in advance as the next work target. Part 4 is changed. Thereafter, each processing of (ST15) to (ST25) is executed, and the electronic component P2 taken out from the changed component supply unit 4 is sequentially mounted on the unit substrate 3a below the unit substrate 3a (6). That is, in this case, if the remaining part count is less than the threshold value (or less than the threshold value), the lot switching processing unit 25 changes the component supply unit 4 to be operated from the component supply unit 4 set at that time. The process which changes to the component supply part 4 is performed.

ここで、(ST16)にて部品品切れ発生を検出する処理を実行するのは、次の理由による。すなわち、動作モード2では、部品残数の管理を採用していることから、本来は部品品切れは発生しないはずである。しかしながら、部品残数のベースとなる各ロット毎の総部品数はオペレータによって入力されることから、総部品数の入力ミスに起因して誤った部品残数が部品残数記憶部36に記憶される事態が排除できない。さらに、部品搭載動作を反復して実行する過程において、ピックアップミスや部品認識NGなどが想定を超える高頻度で発生したような場合には、予め余裕値として見込んだマージンを超えて廃棄部品が発生する。   Here, the reason for executing the process of detecting the out-of-components in (ST16) is as follows. That is, in the operation mode 2, since the management of the remaining number of parts is adopted, the parts should not run out. However, since the total number of parts for each lot, which is the basis for the remaining number of parts, is input by the operator, the wrong remaining part number due to an input mistake in the total number of parts is stored in the remaining part number storage unit 36. It cannot be excluded. Furthermore, in the process of repeatedly executing the component mounting operation, if pick-up mistakes, component recognition NG, etc. occur at a frequency that is higher than expected, discarded components exceed the margin expected as a margin value in advance. To do.

このような部品残数の誤差や想定を超える数の廃棄部品が発生すると、1つの単位基板実装作業を実行中に、作業対象となっている部品供給部4において本来あるはずの電子部品が部品品切れとなる事態が発生し、装置動作エラーとなって部品搭載動作が中断する。このような事態の発生を防ぐため、動作モード2においても動作モード1と同様に、部品品切れ検出部22によって部品切れ発生を検出し、同様の処理を行うようにしている。   When such an error in the remaining number of parts or a number of discarded parts exceeding the assumption occurs, an electronic part that should originally exist in the part supply unit 4 that is the target of work during the execution of one unit board mounting work An out-of-stock situation occurs, resulting in a device operation error, and the component mounting operation is interrupted. In order to prevent the occurrence of such a situation, in the operation mode 2 as well, as in the operation mode 1, the out-of-component detection unit 22 detects the out-of-component occurrence and performs the same processing.

すなわち図10に示すように、電子部品P2が単位基板3a(6)から順次実装され、単位基板3a(11)に6個の電子部品P2を実装した時点で部品品切れが発生すると、図6に示す例と同様の実装点キャンセル処理を行う(ST21)。そしてこれに引き続いてロット切換処理(ST22)が実行される。これにより、作業対象となる部品供給部4を、当該時点で設定されていて部品品切れが発生した部品供給部4から、予め次の作業対象として供給順序が設定された他の部品供給部4に変更する処理を行い、次の単位基板3a(12)を対象として(ST12)に戻り、同様の動作処理が反復実行される。これにより、単位基板3a(12)以降の各単位基板3aには、変更された部品供給部4から連続的に取り出された同一ロットに属する電子部品P3が順次実装される。   That is, as shown in FIG. 10, when the electronic component P2 is sequentially mounted from the unit substrate 3a (6) and six electronic components P2 are mounted on the unit substrate 3a (11), the component is out of stock. A mounting point cancellation process similar to the example shown is performed (ST21). Subsequently, lot switching processing (ST22) is executed. As a result, the component supply unit 4 that is the work target is changed from the component supply unit 4 that has been set at that time and the component is out of stock to another component supply unit 4 that has been set in advance as the next work target. The process to be changed is performed, the next unit substrate 3a (12) is returned to (ST12), and the same operation process is repeatedly executed. As a result, the electronic components P3 belonging to the same lot continuously taken out from the changed component supply unit 4 are sequentially mounted on the unit substrates 3a after the unit substrate 3a (12).

すなわちこの場合には、ロット切換処理部25は、部品残数が閾値未満(または閾値以下)であれば、作業対象となる部品供給部4を当該時点で設定されている部品供給部4から他の部品供給部4に変更する処理を行い、さらに部品品切れ検出部22が単位基板3a(11)(一の単位基板)への単位基板実装作業の途中で部品品切れを検出した場合は、単位基板3a(11)を対象とする単位基板実装作業を中止して単位基板3a(12)(次の単位基板)を対象とする単位基板実装作業へ移行するとともに、作業対象となる部品供給部4を当該時点で設定されている部品供給部4から他の部品供給部4に変更する処理を行う。   That is, in this case, if the remaining part count is less than the threshold value (or less than the threshold value), the lot switching processing unit 25 changes the component supply unit 4 to be operated from the component supply unit 4 set at that time. If the component supply detection unit 22 detects that the component supply is out of the unit substrate 3a (11) (one unit substrate) during the process of mounting the unit substrate on the unit substrate 3a (11) (one unit substrate). The unit board mounting work for 3a (11) is stopped and the unit board mounting work for the unit board 3a (12) (next unit board) is shifted to. A process of changing from the component supply unit 4 set at the time to another component supply unit 4 is performed.

なお上述実施例においては、電子部品実装装置1に複数の部品供給部4を備えており、1つの部品供給部4が部品品切れとなる度に作業対象となる部品供給部4を変更する例を示しているが、本発明は必ずしも複数の部品供給部4を必須構成要件としたものではない。すなわち1つの部品供給部4のみを備えた電子部品実装装置の場合、または複数の部品供給部4を備えた電子部品実装装置において供給順序が最後の部品供給部4が部品品切れとなった場合など、作業対象を他の部品供給部4に変更することができない場合にあっても、本発明を適用することができる。この場合には、異なるロットの電子部品が同一の単位基板3aに混載することを防止するためのロット切換処理に、作業者による手作業を介在させることが必要となる。   In the above-described embodiment, the electronic component mounting apparatus 1 includes a plurality of component supply units 4, and each component supply unit 4 changes the component supply unit 4 as a work target every time the component is out of stock. Although shown, the present invention does not necessarily require a plurality of component supply units 4 as essential constituent requirements. That is, in the case of an electronic component mounting apparatus provided with only one component supply unit 4, or in the case of an electronic component mounting apparatus provided with a plurality of component supply units 4, the last component supply unit 4 in the supply order is out of components. Even when the work target cannot be changed to another component supply unit 4, the present invention can be applied. In this case, it is necessary to intervene a manual operation by an operator in the lot switching process for preventing the electronic components of different lots from being mixedly mounted on the same unit substrate 3a.

例えば、図5に示す動作モード1の場合には、(ST4)にて部品切れが発生し、且つ
その部品品切れ発生時において単位基板実装作業の対象となっている単位基板3aに既に実装済み部品がある場合には、実行中の単位基板実装作業を中止し(ST7)、表示部13によって部品切れである旨の報知を行う。そしてこの報知を承けて、作業者は供給リール4aの交換などの電子部品の補給作業を実行し、作業完了の入力操作を操作・入力部14によって行う。この入力によりロット切換処理部25は、単位基板実装作業が中止された単位基板3aの次の単位基板3aを対象として、単位基板実装作業を開始する。
For example, in the case of the operation mode 1 shown in FIG. 5, a component is cut out in (ST4), and the component already mounted on the unit substrate 3a that is the target of the unit substrate mounting operation when the component is out of stock. If there is, the unit board mounting operation being performed is stopped (ST7), and the display unit 13 notifies that the component is out. In response to this notification, the worker performs a replenishment operation of electronic parts such as replacement of the supply reel 4a, and performs an operation completion input operation by the operation / input unit 14. With this input, the lot switching processing unit 25 starts the unit substrate mounting operation for the unit substrate 3a next to the unit substrate 3a for which the unit substrate mounting operation has been stopped.

また(ST4)にて部品切れが発生したものの、その部品品切れ発生が単位基板実装作業の開始時であって、単位基板実装作業の対象となっている単位基板3aには実装済み部品がない場合には、表示部13によって部品切れである旨の報知を行う。そしてこの報知を承けて作業者は同様に電子部品の補給作業を実行し、作業完了の入力操作を操作・入力部14によって行う。この入力により、ロット切換処理部25は同一の単位基板3aを対象として、単位基板実装作業を開始する。   In addition, when the component out of part occurs in (ST4), the out of component occurrence is at the start of the unit substrate mounting operation, and there is no mounted component on the unit substrate 3a that is the target of the unit substrate mounting operation. In this case, the display unit 13 notifies that the parts are out. In response to this notification, the worker similarly performs a replenishment operation of the electronic component, and performs an operation completion input operation by the operation / input unit 14. With this input, the lot switching processing unit 25 starts unit board mounting work for the same unit board 3a.

すなわちこの場合においては、ロット切換処理部25は、部品品切れ検出工程において一の単位基板3aへの単位基板実装作業の途中で部品品切れを検出したならば、当該一の単位基板3aへの単位基板実装作業を中止してその旨報知するとともに、作業者による部品供給部4への電子部品の補給作業が完了した旨の入力を受けた後に、次の単位基板3aに対する単位基板実装作業へ移行する処理を行う(ロット切換処理工程)。   That is, in this case, if the lot switching processing unit 25 detects that a component is out of the process of mounting the unit substrate on one unit substrate 3a in the component out of stock detection step, the unit substrate on the one unit substrate 3a is detected. After stopping the mounting operation and notifying that effect, and receiving an input to the effect that the operator has completed the replenishment operation of the electronic components to the component supply unit 4, the operation shifts to the unit substrate mounting operation for the next unit substrate 3a. Processing is performed (lot switching processing step).

そしてロット切換処理部25は、前記部品切れ検出工程において、部品品切れ検出部22が一の単位基板3aへの単位基板実装作業の開始時に部品品切れを検出したならば、前記ロット切換処理工程においてその旨報知するとともに、作業者による部品供給部4への電子部品の補給作業が完了した旨の入力を受けた後に、次の単位基板3aへの単位基板実装作業へ移行することなく、同一の単位基板3aを対象とする単位基板実装作業を開始する。   Then, in the part switching detection step, the lot switching processing unit 25, if the component out of stock detection unit 22 detects the out of component at the start of the unit board mounting work on one unit board 3a, the lot switching processing step And the same unit without moving to the next unit board mounting work on the unit board 3a after receiving the input to the effect that the operator has completed the replenishment work of the electronic parts to the parts supply unit 4 The unit board mounting work for the board 3a is started.

また図9に示す動作モード2において、部品残数記憶部36に記憶された部品残数のみに基づいて部品実装作業を管理する場合には、ロット切換処理部25は、単位基板実装作業開始(ST15)の前に(ST13)にて実行される部品残数比較部24による判定結果により、部品残数が閾値未満であれば、当該単位基板3aへの単位基板実装作業を中止してその旨報知するとともに、作業者による部品供給部4への電子部品の補給作業が完了した旨の入力を受けた後に、当該単位基板3aを対象とする単位基板実装作業を開始する。   Further, in the operation mode 2 shown in FIG. 9, when managing the component mounting work based only on the remaining component number stored in the remaining component number storage unit 36, the lot switching processing unit 25 starts the unit board mounting operation ( If the remaining component number is less than the threshold value as a result of the determination by the remaining component number comparison unit 24 executed in (ST13) before (ST15), the unit substrate mounting work on the unit substrate 3a is stopped and that effect is confirmed. After notifying and receiving an input indicating that the operator has completed the replenishment operation of the electronic component to the component supply unit 4, the unit substrate mounting operation for the unit substrate 3a is started.

さらに動作モード2において、部品残数に加えて部品品切れ検出の有無を併用して部品実装作業を管理する場合には、ロット切換処理部25は以下の処理を行う。すなわち、部品残数比較部24による判定結果により、部品残数が閾値未満であれば、当該単位基板3aへの単位基板実装作業を中止してその旨報知するとともに、作業者による電子部品の補給作業が完了した旨の入力を受けた後に、当該単位基板3aを対象とする単位基板実装作業を開始する処理を行う。そしてさらに部品品切れ検出部22が一の単位基板3aへの単位基板実装作業の途中で部品品切れを検出した場合は、当該単位基板3aへの単位基板実装作業を中止してその旨報知し、作業者による部品供給部4への電子部品の補給作業が完了した旨の入力を受けた後に、次の単位基板3aを対象とする単位基板実装作業へ移行する処理を行う。   Furthermore, in the operation mode 2, when managing the component mounting operation using the presence / absence of component out of stock detection in addition to the remaining component count, the lot switching processing unit 25 performs the following processing. That is, if the remaining number of components is less than the threshold value as a result of determination by the remaining component number comparing unit 24, the unit substrate mounting work on the unit substrate 3a is stopped and notified to that effect, and the electronic component is supplied by the operator. After receiving an input indicating that the work has been completed, a process of starting a unit board mounting work for the unit board 3a is performed. Further, when the component out of stock detection unit 22 detects the out of component product in the middle of the unit substrate mounting operation on one unit substrate 3a, the unit substrate mounting operation on the unit substrate 3a is stopped and notified to that effect. After receiving an input indicating that the replenishment operation of the electronic component to the component supply unit 4 by the person is completed, a process of shifting to the unit substrate mounting operation for the next unit substrate 3a is performed.

上述の場合において、ロット切換処理部25は、部品品切れ検出部22が一の単位基板3aへの単位基板実装作業の開始時に部品品切れを検出した場合は、その旨報知するとともに、作業者による部品供給部4への電子部品の補給作業が完了した旨の入力を受けた後に、次の単位基板3aを対象とする単位基板実装作業へ移行することなく、同一の単位基
板3aを対象とする単位基板実装作業を始めから実行する。
In the above-described case, the lot switching processing unit 25 notifies the fact when the component out-of-stock detection unit 22 detects out-of-component parts at the start of the unit substrate mounting work on one unit substrate 3a, and notifies the parts by the operator. After receiving an input to the supply unit 4 that the electronic component replenishment work has been completed, the unit for the same unit board 3a is not transferred to the unit board mounting work for the next unit board 3a. Perform board mounting from the beginning.

上記説明したように、本実施の形態に示す動作モード1においては、多面取り基板3に同一種類の電子部品を実装する実装作業において、部品供給部4からの電子部品の取出しが所定回数連続して失敗したことを以て電子部品の品切れを検出し、一の単位基板3aを対象とする単位基板実装作業の途中で部品品切れを検出したならば、当該一の単位基板3aを対象とする単位基板実装作業を中止して次の単位基板3aを対象とする単位基板実装作業に移行するとともに、作業対象となる部品供給部4を当該時点で設定されている部品供給部4から他の部品供給部4に変更するロット切換処理、または作業者による電子部品の補給作業が完了した旨の入力を受けた後に次の単位基板3aに対する単位基板実装作業へ移行するロット切換処理を行うようにしている。   As described above, in the operation mode 1 shown in the present embodiment, in the mounting operation for mounting the same type of electronic component on the multi-sided board 3, the electronic component is continuously taken out from the component supply unit 4 a predetermined number of times. If it is detected that the electronic component is out of stock and the out-of-component component is detected during the unit substrate mounting operation for one unit substrate 3a, the unit substrate mounting for the one unit substrate 3a is performed. The operation is stopped and the process shifts to a unit substrate mounting operation for the next unit substrate 3a, and the component supply unit 4 to be operated is changed from the component supply unit 4 set at that time to another component supply unit 4 Lot switching processing to be changed to, or lot switching processing for shifting to unit board mounting work for the next unit board 3a after receiving an input to the effect that the worker has replenished electronic components. It is way.

また本実施の形態に示す動作モード2においては、多面取り基板3に同一種類の電子部品を実装する実装作業において、部品供給部4における電子部品の残数を部品残数として記憶しておき、1つの単位基板3aを対象とする単位基板実装作業を開始する前に、部品品切れが発生する可能性の有無を判定するために設定された閾値と部品残数とを比較して部品残数が閾値未満であるか否かを判定し、部品残数が閾値未満であれば作業対象となる部品供給部4を当該時点で設定されている部品供給部から他の部品供給部4に変更するロット切換処理を行うようにしている。これにより、LED素子などの同一種類の複数の電子部品を基板に実装する実装形態において、ロットが異なる部品の混載を防止することができる。   In the operation mode 2 shown in the present embodiment, in the mounting operation for mounting the same type of electronic component on the multi-sided board 3, the remaining number of electronic components in the component supply unit 4 is stored as the remaining component number. Before starting the unit board mounting operation for one unit board 3a, the remaining part number is determined by comparing the threshold value set for determining whether or not there is a possibility that the part will run out and the remaining part number. It is determined whether or not the number is less than the threshold value, and if the remaining number of parts is less than the threshold value, the part supply unit 4 to be operated is changed from the component supply unit set at that time to another component supply unit 4 Switching processing is performed. Thereby, in the mounting form which mounts several electronic components of the same kind, such as an LED element, on a board | substrate, the mixed mounting of the components from which a lot differs can be prevented.

本発明の電子部品実装装置および電子部品実装方法は、同一種類の複数の電子部品を基板に実装する実装形態においてロットが異なる部品の混載を防止することができるという効果を有し、LED素子など同一品種であっても特性が異なる電子部品を実装する分野において有用である。   The electronic component mounting apparatus and electronic component mounting method of the present invention have the effect of preventing mixed mounting of components of different lots in a mounting form in which a plurality of electronic components of the same type are mounted on a substrate, such as LED elements. Even in the same type, it is useful in the field of mounting electronic components having different characteristics.
