The component mounter picks up a component supplied from a component supply unit and mounts it at a component mounting position on the substrate by a mounting head provided movably with respect to the positioned substrate. An inspection machine is arranged upstream or downstream of the component mounting machine in the component mounting line, and a component mounting position on the board is inspected (recognized) by a recognition camera provided in the inspection machine. Here, the inspection machine installed on the upstream side of the component mounting machine performs an inspection (pre-inspection) such as whether or not the component mounting position on the board on which the component is mounted is damaged by the downstream component mounting machine. The inspection machine installed on the downstream side of the component mounting machine performs an inspection (post-inspection) such as whether the component mounted by the upstream component mounting machine is normally mounted at the component mounting position on the board. (Patent Document 1).
JP 2005-5290 A

しかしながら、上記のように、検査機が部品実装機の上流又は下流側に部品実装機とは別個の装置として配置される場合、部品実装機は、その上流側の検査機が検査(前検査)を行っている間は、基板上に検査が終了した部品搭載位置があってもその部品搭載位置に部品搭載を行うことができず、部品実装機の下流側の検査機は、部品実装機が部品搭載を行っている間は、基板上に部品搭載が終了した部品搭載位置があってもその部品搭載位置の検査(後検査)を行うことができなかった。このため装置間で待ち時間が生じ、その分生産効率が低下する場合があった。   However, as described above, when the inspection machine is arranged as an apparatus separate from the component mounting machine upstream or downstream of the component mounting machine, the component mounting machine is inspected by the upstream inspection machine (pre-inspection). During the inspection, even if there is a component mounting position on the board that has been inspected, component mounting cannot be performed at that component mounting position. During component mounting, even if there was a component mounting position on the board where component mounting was completed, the component mounting position could not be inspected (post-inspection). For this reason, a waiting time is generated between the apparatuses, and the production efficiency may be reduced accordingly.

そこで本発明は、部品搭載位置の検査(前検査又は後検査)を行いながら部品の搭載を実行できるようにして生産効率を向上させることができる部品実装機及び部品実装方法を提供することを目的とする。   SUMMARY OF THE INVENTION The present invention provides a component mounting machine and a component mounting method capable of improving the production efficiency by enabling the mounting of components while performing the inspection (pre-inspection or post-inspection) of the component mounting position. And

請求項1に記載の部品実装機は、位置決めされた基板に対して移動自在に設けられた搭載ヘッドにより、部品供給部より供給される部品をピックアップして基板上の部品搭載位置に搭載する部品実装機であって、搭載ヘッドとは独立して移動自在に設けられた認識カメラと、搭載ヘッドが部品供給部より部品をピックアップしている間に認識カメラによって部品搭載位置の認識を行わせる認識カメラ制御手段とを備えた。   The component mounting machine according to claim 1, wherein a component supplied from a component supply unit is picked up and mounted at a component mounting position on the substrate by a mounting head provided movably with respect to the positioned substrate. A recognition camera that is a mounting machine that can be moved independently of the mounting head and a recognition camera that recognizes the component mounting position while the mounting head picks up the component from the component supply unit. Camera control means.

請求項2に記載の部品実装機は、請求項1に記載の部品実装機であって、認識カメラ制御手段は、認識カメラがまだ認識していない部品搭載位置の中から、搭載ヘッドにより部品が搭載される順番の最も早いものを抽出し、その抽出した部品搭載位置を含む一又は複数の部品搭載位置を認識対象として認識カメラに認識させる。   The component mounter according to claim 2 is the component mounter according to claim 1, wherein the recognition camera control means sets the component by the mounting head from among the component mounting positions not yet recognized by the recognition camera. The earliest in order of mounting is extracted, and one or a plurality of component mounting positions including the extracted component mounting positions are recognized by the recognition camera as recognition targets.

請求項3に記載の部品実装方法は、位置決めされた基板に対して移動自在に設けられた搭載ヘッドにより、部品供給部より供給される部品をピックアップして基板上の部品搭載位置に搭載する部品実装方法であって、搭載ヘッドが部品供給部より部品をピックアップしている間に、搭載ヘッドとは独立して移動自在に設けられた認識カメラによって部品搭載位置の認識を行う。   The component mounting method according to claim 3, wherein a component supplied from a component supply unit is picked up and mounted at a component mounting position on the substrate by a mounting head provided movably with respect to the positioned substrate. In the mounting method, while the mounting head picks up a component from the component supply unit, the component mounting position is recognized by a recognition camera that is movably provided independently of the mounting head.

請求項4に記載の部品実装方法は、請求項3に記載の部品実装方法であって、認識カメラによる部品搭載位置の認識は、認識カメラがまだ認識していない部品搭載位置の中から、搭載ヘッドにより部品が搭載される順番の最も早いものを抽出し、その抽出した部品搭載位置を含む一又は複数の部品搭載位置を認識対象として行う。   The component mounting method according to claim 4 is the component mounting method according to claim 3, wherein the recognition of the component mounting position by the recognition camera is performed from among the component mounting positions not yet recognized by the recognition camera. The head with the earliest order in which components are mounted is extracted, and one or more component mounting positions including the extracted component mounting positions are recognized.

本発明では、搭載ヘッドが部品供給部より部品をピックアップしている間に、搭載ヘッドとは独立して移動自在に設けられた認識カメラによって部品搭載位置の認識を行うようになっており、認識カメラによる部品搭載位置の検査(前検査又は後検査)を、搭載ヘッドによる部品搭載と並行して行うことができる。このため部品搭載位置の検査を行いながら部品の搭載を実行でき、生産効率を大幅に向上させることができる。   In the present invention, while the mounting head picks up a component from the component supply unit, the component mounting position is recognized by a recognition camera that is movably provided independently of the mounting head. The inspection (pre-inspection or post-inspection) of the component mounting position by the camera can be performed in parallel with the component mounting by the mounting head. For this reason, mounting of parts can be executed while inspecting the mounting position of the parts, and the production efficiency can be greatly improved.

また、認識カメラによる部品搭載位置の認識が、認識カメラがまだ認識していない部品搭載位置の中から、搭載ヘッドにより部品が搭載される順番の最も早いものを抽出し、その抽出した部品搭載位置を含む一又は複数の部品搭載位置を認識対象として行うようになっているので、認識カメラによる部品搭載位置の検査(前検査又は後検査)を、搭載ヘッドによる部品搭載順序を基準とした順序で行うことができ、認識カメラにより前検査を行う場合には、他の部品搭載位置についての検査を先取りして行うこともできる。このため、認識カメラが前検査を行うものであれば、搭載ヘッドが部品を部品搭載位置に搭載する前にその部品搭載位置の検査を終わらせておくことができ、認識カメラが後検査を行うものであれば、搭載ヘッドが部品の搭載を終了するのとほぼ同時に部品搭載位置の検査を終了させることができる。   In addition, the component mounting position recognized by the recognition camera is extracted from the component mounting positions not yet recognized by the recognition camera, and the component mounting position extracted in the earliest order is mounted by the mounting head. Since one or a plurality of component mounting positions including the target is recognized as a recognition target, the component mounting position inspection (pre-inspection or post-inspection) by the recognition camera is performed in the order based on the component mounting order by the mounting head. In the case where the pre-inspection is performed by the recognition camera, it is possible to perform the inspection for other component mounting positions in advance. Therefore, if the recognition camera performs pre-inspection, the mounting head can finish the inspection of the component mounting position before the mounting head mounts the component at the component mounting position, and the recognition camera performs the post-inspection. If it is a thing, the inspection of a component mounting position can be complete | finished substantially at the same time as a mounting head complete | finishes mounting of a component.

Further, in the storage device 22 connected to the control device 21, the type of the component P accommodated in each component supply unit 15, the mounting position (target mounting position) of each component P on the substrate 3, and each component P Various data including data such as the mounting order (component mounting order) on the board 3 is stored.

次に、図4のフローチャートを用いて部品実装機1により部品Pを基板3に搭載する部品実装工程の流れについて説明する。ここで示す部品実装機1による部品実装工程の流れは、本発明の一実施の形態における部品実装方法の実行手順を含んだものとなっている。   Next, the flow of the component mounting process for mounting the component P on the board 3 by the component mounting machine 1 will be described using the flowchart of FIG. The flow of the component mounting process by the component mounting machine 1 shown here includes an execution procedure of the component mounting method according to the embodiment of the present invention.

部品実装機1による部品実装工程では、制御装置21は先ず、搬送コンベア駆動モータ20aの作動制御により搬送コンベア4を駆動して基板3を部品実装機1内に搬入し(図4におけるステップST1の基板搬入工程)、基板3を所定位置に位置決めする(ステップST2の基板位置決め工程)。このステップST2の基板位置決め工程では、制御装置21は、搭載ヘッド9を基板3の上方に移動させ、搭載ヘッド9に設けられた基板カメラ16に基板3の位置決めマーク(図示せず)の認識(撮像)を行わせて、基板3の基準位置からの位置ずれを求める。   In the component mounting process by the component mounting machine 1, the control device 21 first drives the transport conveyor 4 by controlling the operation of the transport conveyor drive motor 20a to carry the board 3 into the component mounter 1 (in step ST1 in FIG. 4). Substrate loading step), the substrate 3 is positioned at a predetermined position (substrate positioning step of step ST2). In the substrate positioning process of step ST2, the control device 21 moves the mounting head 9 above the substrate 3 and recognizes a positioning mark (not shown) of the substrate 3 on the substrate camera 16 provided on the mounting head 9 ( Imaging) is performed, and the positional deviation of the substrate 3 from the reference position is obtained.

制御装置21は、ステップST2の基板位置決め工程が終了したら、記憶装置22に記憶されたデータの読み込みを行う(ステップST3のデータ読み込み工程)。制御装置21はステップST3のデータ読み込み工程が終了したら、この読み込んだデータに基づいて、搭載ヘッド9に以下の部品搭載プロセス(ステップST4〜ステップST8)を実行させる。   When the substrate positioning process in step ST2 is completed, the control device 21 reads data stored in the storage device 22 (data reading process in step ST3). When the data reading process in step ST3 is completed, the control device 21 causes the mounting head 9 to execute the following component mounting process (steps ST4 to ST8) based on the read data.

部品搭載プロセスでは、先ず、制御装置21は、搭載ヘッド9を移動させて、各部品供給部15の部品供給口15aに供給される部品Pを搭載ヘッド9の吸着ノズル14にピックアップ(吸着)させる(ステップST4の部品ピックアップ工程)。そして、搭載ヘッド9を部品カメラ17の直上に移動させ、部品カメラ17に部品Pの認識(撮像)を行わせて、部品Pの吸着ノズル14に対する位置ずれを求める(ステップST5の部品認識工
程)。
In the component mounting process, first, the control device 21 moves the mounting head 9 and picks up (sucks) the component P supplied to the component supply port 15a of each component supply unit 15 to the suction nozzle 14 of the mounting head 9. (Part pickup process in step ST4). Then, the mounting head 9 is moved immediately above the component camera 17, and the component camera 17 recognizes (images) the component P, thereby obtaining a positional shift of the component P with respect to the suction nozzle 14 (component recognition step in step ST5). .

制御装置21は、ステップST5の部品認識工程が終了したら、現在ピックアップしている(すなわち、これから基板3に搭載しようとしている)部品Pが搭載される基板3上の部品搭載位置Lの検査(ここでは部品搭載前の前検査)が既に終了しているかどうかを調べる(ステップST6)。その結果、これから搭載しようとしている部品Pの部品搭載位置Lの検査(前検査)が終了していなかったときにはその検査が終了するまで待機し、検査が終了していたときには、その部品搭載位置Lに部品Pを搭載する(ステップST7の部品搭載工程)。部品Pを部品搭載位置Lに搭載するときには、ステップST2で求めた基板3の基準位置からの位置ずれと、ステップST5で求めた部品Pの吸着ノズル14に対する位置ずれが補正されるようにする。   When the component recognition process in step ST5 is completed, the control device 21 inspects the component mounting position L on the substrate 3 on which the component P currently picked up (that is, the component P to be mounted on the substrate 3 from now on) is mounted (here. Then, it is checked whether the pre-inspection before component mounting has already been completed (step ST6). As a result, when the inspection (pre-inspection) of the component mounting position L of the component P to be mounted is not completed, the process waits until the inspection is completed, and when the inspection is completed, the component mounting position L The component P is mounted on (component mounting step of step ST7). When the component P is mounted at the component mounting position L, the positional deviation from the reference position of the substrate 3 obtained in step ST2 and the positional deviation of the component P with respect to the suction nozzle 14 obtained in step ST5 are corrected.

ステップST6の段階で、これから基板3に搭載しようとしている部品Pの部品搭載位置Lの検査が終了しているかどうかは、この部品搭載プロセス(ステップ4〜ステップST8)と並行して認識カメラ19によって行われる後述の部品搭載位置検査プロセス(ステップST11〜ステップST15)の進捗状況によるが、後述するように、認識カメラ19は搭載ヘッド9に先んじて(前倒しで)部品搭載位置Lの検査(前検査)を実行するので、ステップST6に至った段階では、これから搭載しようとしている部品Pの部品搭載位置Lの認識は既に終了しており、通常はステップST6で搭載ヘッド9が待機することはない。   In step ST6, whether or not the inspection of the component mounting position L of the component P to be mounted on the board 3 is completed is confirmed by the recognition camera 19 in parallel with this component mounting process (step 4 to step ST8). Depending on the progress of a component mounting position inspection process (steps ST11 to ST15) to be described later, the recognition camera 19 inspects the component mounting position L prior to the mounting head 9 (advanced) as described later. In step ST6, the recognition of the component mounting position L of the component P to be mounted has already been completed, and the mounting head 9 does not normally stand by in step ST6.

制御装置21は、ステップST7の部品搭載工程が終了したら、基板3に搭載しようとしている全ての部品Pの基板3への搭載が終了したかどうかを調べる(ステップST8)。その結果、全ての部品Pの基板3への搭載が終了しなかったときにはステップST4に戻って次の部品Pのピックアップ及び基板3への搭載を含む部品搭載動作(ステップST4〜ステップST7)を実行させ、全ての部品Pの基板3への搭載が終了していたときには 搬送コンベア4によって基板3を部品実装機1の外部に排出し(ステップST9の基板搬出工程)、その基板3への部品実装を終了する。   When the component mounting process in step ST7 is completed, the control device 21 checks whether or not mounting of all the components P to be mounted on the substrate 3 has been completed (step ST8). As a result, when the mounting of all the components P on the board 3 is not completed, the process returns to step ST4 to execute the component mounting operation including the pickup of the next component P and the mounting on the board 3 (step ST4 to step ST7). When all the components P have been mounted on the board 3, the board 3 is discharged out of the component mounting machine 1 by the transfer conveyor 4 (board unloading process in step ST9), and the parts are mounted on the board 3. Exit.

制御装置21は前述のように、部品搭載プロセス(ステップST4〜ステップST8)と並行して認識カメラ19に部品搭載位置検査プロセス(ステップST11〜ステップST15)を実行させる。この部品搭載位置検査プロセスでは、基板3上の部品搭載位置Lが汚損されていなかどうか、或いは、部品Pがシールド部品である場合に、そのシールド部品によって覆われる部品(このシールド部品によって覆われる部品は、この部品実装機1の上流に配置された他の部品実装機によって基板3上に実装される)が部品搭載位置Lに正常に搭載されているかどうか等の検査(前検査)を行う。   As described above, the control device 21 causes the recognition camera 19 to execute the component mounting position inspection process (step ST11 to step ST15) in parallel with the component mounting process (step ST4 to step ST8). In this component mounting position inspection process, whether or not the component mounting position L on the substrate 3 is fouled, or when the component P is a shield component, the component covered by the shield component (the component covered by this shield component) Is mounted on the board 3 by another component mounter disposed upstream of the component mounter 1) (pre-inspection) such as whether or not it is normally mounted at the component mounting position L.

部品搭載位置検査プロセス(ステップST11〜ステップST15)では、制御装置21は先ず、ステップST3の終了後に、搭載ヘッド9が部品搭載順序に対応する(部品搭載順序に従った)番号を基板3上の部品搭載位置Lに割り付ける(ステップST11の番号割り付け工程)。例えば、図5(a)のように基板3上に24個の部品搭載位置Lがあり、搭載ヘッド9の部品搭載順序が図5(a)中に示す矢印Aの進む順であった場合には、制御装置21は、基板3上の24個の部品搭載位置Lに対し、図5(b)のように、矢印Aの進む順に「1」から「24」までの番号を割り付ける。   In the component mounting position inspection process (steps ST11 to ST15), the control device 21 first assigns the number corresponding to the component mounting order (according to the component mounting order) on the substrate 3 after the end of step ST3. Assigned to the component mounting position L (number assignment step of step ST11). For example, when there are 24 component mounting positions L on the substrate 3 as shown in FIG. 5A, and the component mounting order of the mounting head 9 is in the order in which the arrow A shown in FIG. The control device 21 assigns numbers from “1” to “24” to the 24 component mounting positions L on the board 3 in the order of the arrow A as shown in FIG.

制御装置21は、ステップST11の番号割り付け工程が終了したら、認識カメラ19がまだ認識していない部品搭載位置Lの中から、搭載ヘッド9により部品Pが搭載される順番の最も早いものを抽出し(ステップST12の抽出工程)、その抽出した部品搭載位置Lを含む一又は複数の部品搭載位置Lを認識対象として選定する(ステップST13の選定工程)。そして、制御装置21は、ステップST13の選定工程で認識カメラ19に
よって検査(認識)しようとする一又は複数の部品搭載位置Lを選定したら、認識カメラ19の認識視野がその選定した一又は複数の部品搭載位置Lが含まれるものとなるように認識カメラ19を移動させ、その認識視野で認識カメラ19に認識(撮像)させる(ステップST14の認識工程)。
When the number assigning process of step ST11 is completed, the control device 21 extracts the component in the earliest order in which the component P is mounted by the mounting head 9 from the component mounting positions L that the recognition camera 19 has not yet recognized. (Extraction step of step ST12), one or a plurality of component mounting positions L including the extracted component mounting positions L are selected as recognition targets (selection step of step ST13). When the control device 21 selects one or more component mounting positions L to be inspected (recognized) by the recognition camera 19 in the selection process of step ST13, the recognition field of view of the recognition camera 19 is the selected one or more. The recognition camera 19 is moved so that the component mounting position L is included, and the recognition camera 19 is recognized (imaged) in the recognition field of view (recognition step of step ST14).

例えば図5(a),(b)の例では、1回目の認識では、認識カメラ19がまだ認識していない番号「1」〜「24」の24個の部品搭載位置Lの中で最も小さい番号「1」の部品搭載位置Lを抽出し、その抽出した番号「1」の部品搭載位置Lを認識対象として選定し(図6(a)中に示す認識視野R1参照)、その選定した番号「1」の部品搭載位置Lを、認識カメラ19により認識視野R1で認識させる。   For example, in the examples of FIGS. 5A and 5B, the first recognition is the smallest of the 24 component mounting positions L of numbers “1” to “24” that have not yet been recognized by the recognition camera 19. The component mounting position L with the number “1” is extracted, the extracted component mounting position L with the number “1” is selected as a recognition target (see the recognition field of view R1 shown in FIG. 6A), and the selected number is selected. The component mounting position L of “1” is recognized by the recognition camera 19 in the recognition visual field R1.

ステップST14の認識工程は、搭載ヘッド9が部品供給部15より部品Pをピックアップしている間(ステップST4の部品ピックアップ工程及びその前後)に認識カメラ19を基板3の上方に進出させて行う。このように、認識カメラ19による部品搭載位置Lの検査(認識)を、搭載ヘッド9が基板3に部品Pの搭載を行っていない間に行うことにより、搭載ヘッド9による部品搭載動作(ステップST4〜ステップST7)の進行を妨げることなく、認識カメラ19による認識動作(ステップST11〜ステップST14)を実行させることができる。   The recognition process in step ST14 is performed by moving the recognition camera 19 to the upper side of the substrate 3 while the mounting head 9 is picking up the component P from the component supply unit 15 (the component pickup process in step ST4 and before and after). In this way, the component mounting position L is inspected (recognized) by the recognition camera 19 while the mounting head 9 is not mounting the component P on the substrate 3, so that the component mounting operation by the mounting head 9 (step ST 4). The recognition operation (step ST11 to step ST14) by the recognition camera 19 can be executed without hindering the progress of step ST7).

制御装置21は、ステップST14の認識工程が終了したら、基板3上の全ての部品搭載位置Lの認識が終了したかどうかを調べる(ステップST15)。その結果、基板3上の全ての部品搭載位置Lの認識が終了していなかったときにはステップST12に戻って新たに部品搭載位置Lの抽出、選定及び認識を実行し、基板3上の全ての部品搭載位置Lの認識が終了していたときには、この部品搭載位置検査プロセス(ステップST11〜ステップST15)を終了する。   When the recognition process in step ST14 is completed, the control device 21 checks whether or not the recognition of all the component mounting positions L on the board 3 has been completed (step ST15). As a result, when the recognition of all the component mounting positions L on the board 3 has not been completed, the process returns to step ST12 to newly extract, select and recognize the component mounting positions L, and all the parts on the board 3 are detected. When the recognition of the mounting position L has been completed, this component mounting position inspection process (step ST11 to step ST15) is ended.

部品搭載位置検査プロセス(ステップST11〜ステップST15)のステップST15において、基板3上の全ての部品搭載位置Lの認識が終了しておらず、ステップST14からステップST12に戻って新たに部品搭載位置Lの抽出、選定決定及び認識を実行するときには、前回の選定工程(ステップST13)が終了するまでに既に認識対象として選定を終えている部品搭載位置Lを除いた残りの部品搭載位置Lの中から最も小さい番号の部品搭載位置Lを抽出し、その抽出した部品搭載位置Lを新たな認識対象として選定する。例えば図5(a),(b)の例では、1回目の選定工程で「1」の部品搭載位置Lを認識対象として選定したときには、2回目の選定工程では残りの番号「2」〜「24」の23個の部品搭載位置Lのうち最も小さい番号「2」の部品搭載位置Lを抽出し、その抽出した部品搭載位置Lを認識対象として選定する(図6(b)中に示す認識視野R2参照)。この手順によれば、基板3上の24個の部品搭載位置Lは、「1」→「2」→・・・→「24」の順で(すなわち部品搭載順序通りに)認識対象として選定され、認識カメラ19によって検査(認識)されることになる。   In step ST15 of the component mounting position inspection process (steps ST11 to ST15), recognition of all the component mounting positions L on the board 3 has not been completed, and the process returns from step ST14 to step ST12 to newly start the component mounting position L. When performing extraction, selection determination and recognition, the remaining component mounting positions L excluding the component mounting positions L that have already been selected as recognition targets by the end of the previous selection step (step ST13) are selected. The component mounting position L with the smallest number is extracted, and the extracted component mounting position L is selected as a new recognition target. For example, in the example of FIGS. 5A and 5B, when the component mounting position L of “1” is selected as a recognition target in the first selection process, the remaining numbers “2” to “2” are selected in the second selection process. The component mounting position L with the smallest number “2” is extracted from the 23 component mounting positions L of “24”, and the extracted component mounting position L is selected as a recognition target (the recognition shown in FIG. 6B). Field of view R2). According to this procedure, 24 component mounting positions L on the board 3 are selected as recognition targets in the order of “1” → “2” →... → “24” (that is, according to the component mounting order). Inspected (recognized) by the recognition camera 19.

上記の例は、認識対象として1つの部品搭載位置Lのみを選定した場合のものであるが、認識対象として複数の部品搭載位置Lを選定して複数の部品搭載位置Lを同時に検査(認識)するようにしてもよい。例えば図5(a),(b)の例において、1回目の選定工程(ステップST13)で、番号「1」〜「24」の24個の部品搭載位置Lのうち、最も小さい番号「1」の部品搭載位置Lと併せて、その隣に位置する番号「2」の部品搭載位置Lを認識対象として選定することができる(図7(a)中に示す認識視野R11参照)。この場合、2回目の選定工程では残りの番号「3」〜「24」の22個の部品搭載位置Lのうち、最も小さい番号「3」の部品搭載位置Lと併せて、その隣に位置する番号「4」の部品搭載位置Lを認識対象として選定する(図7(b)中に示す認識視野R12参照)。この手順によれば、基板3上の24個の部品搭載位置Lは、「1,2」→「3,4
」・・・→「23,24」の順で認識対象として選定され、認識カメラ19によって認識される。
In the above example, only one component mounting position L is selected as a recognition target. However, a plurality of component mounting positions L are selected as recognition targets and a plurality of component mounting positions L are simultaneously inspected (recognized). You may make it do. For example, in the example of FIGS. 5A and 5B, in the first selection process (step ST13), the smallest number “1” among the 24 component mounting positions L of the numbers “1” to “24”. In addition to the component mounting position L, the component mounting position L of the number “2” located next to the component mounting position L can be selected as a recognition target (see the recognition visual field R11 shown in FIG. 7A). In this case, in the second selection step, among the remaining 22 component mounting positions L of “3” to “24”, the component mounting position L with the smallest number “3” is positioned next to it. The component mounting position L with the number “4” is selected as a recognition target (see the recognition visual field R12 shown in FIG. 7B). According to this procedure, the 24 component mounting positions L on the board 3 are “1, 2” → “3,4”
... → is selected as a recognition target in the order of “23, 24” and recognized by the recognition camera 19.

或いは、図5(a),(b)の例において、1回目の選定工程(ステップST12)で、番号「1」〜「24」の24個の部品搭載位置Lのうち、最も小さい番号「1」の部品搭載位置Lと併せて、その近傍に位置する番号「2」,「11」及び「12」の3つの部品搭載位置Lを認識対象として選定することができる(図8(a)中に示し認識視野R21参照)。この場合、2回目の選定工程(ステップST12)では、残りの番号「3」〜「10」及び「13」〜「24」の20個の部品搭載位置Lのうち、最も小さい番号「3」の部品搭載位置Lと併せて、その近傍に位置する番号「4」,「9」及び「10」の3つの部品搭載位置Lを認識対象として選定する(図8(b)中に示す認識視野R22)。この手順によれば、基板3上の24個の部品搭載位置Lは、「1,2,11,12」→「3,4,9,10」→「5,6,7,8」→「13,14,23,24」→「15,16,21,22」→「17,18,19,20」の順で認識対象として選定され、認識カメラ19によって認識される。   Alternatively, in the example of FIGS. 5A and 5B, in the first selection step (step ST12), the smallest number “1” among the 24 component mounting positions L of the numbers “1” to “24”. In addition to the component mounting position L of “”, three component mounting positions L of numbers “2”, “11” and “12” positioned in the vicinity thereof can be selected as recognition targets (in FIG. 8A). (See recognition field of view R21). In this case, in the second selection step (step ST12), the smallest number “3” among the 20 component mounting positions L of the remaining numbers “3” to “10” and “13” to “24”. In addition to the component mounting position L, three component mounting positions L of numbers “4”, “9” and “10” located in the vicinity thereof are selected as recognition targets (recognition visual field R22 shown in FIG. 8B). ). According to this procedure, the 24 component mounting positions L on the board 3 are “1, 2, 11, 12” → “3,4,9,10” → “5,6,7,8” → “ 13, 14, 23, 24 ”→“ 15, 16, 21, 22, ”→“ 17, 18, 19, 20 ”are selected as recognition targets and recognized by the recognition camera 19.

ここで、認識カメラ19による部品搭載位置Lの検査(認識)に要する時間は通常、搭載ヘッド9が部品Pのピックアップのために部品供給部15へ移動して基板3の上方に戻ってくるまでに要する時間の数分の一であるので、搭載ヘッド9が部品搭載動作(ステップST4〜ステップST7)の1ターンを行う間に、認識カメラ19は数視野分の認識を連続的に行うことができる。このため、認識カメラ19は搭載ヘッド9に先んじて(前倒しで)部品搭載位置Lの検査を実行することができる。なお、ステップST7の部品搭載工程は、部品搭載位置検査プロセス(ステップST11〜ステップST15)において検査(前検査)が終了したものについてのみ行われることから、ステップST8において、基板3に搭載すべき部品Pの全ての搭載が終了したと判断される以前に部品搭載位置検査プロセスは終了する。   Here, the time required for the inspection (recognition) of the component mounting position L by the recognition camera 19 is usually until the mounting head 9 moves to the component supply unit 15 to pick up the component P and returns to the upper side of the substrate 3. Therefore, the recognition camera 19 can continuously recognize several fields of view while the mounting head 9 performs one turn of the component mounting operation (step ST4 to step ST7). it can. For this reason, the recognition camera 19 can execute the inspection of the component mounting position L prior to the mounting head 9 (before moving forward). Note that the component mounting process in step ST7 is performed only for components that have been inspected (pre-inspection) in the component mounting position inspection process (steps ST11 to ST15), so in step ST8, the components to be mounted on the substrate 3 The part mounting position inspection process ends before it is determined that all mounting of P has been completed.

以上説明したように、本実施の形態における部品実装機1は、搭載ヘッド9とは独立して移動自在に設けられた認識カメラ19及び搭載ヘッド9が部品供給部15より部品Pをピックアップしている間に認識カメラ19によって部品搭載位置Lの認識を行わせる認識カメラ制御手段(制御装置21)を備えたものとなっており、本実施の形態における部品実装方法は、搭載ヘッド9が部品供給部15より部品Pをピックアップしている間に、搭載ヘッド9とは独立して移動自在に設けられた認識カメラ19によって部品搭載位置Lの認識を行うものとなっている。   As described above, in the component mounter 1 according to the present embodiment, the recognition camera 19 and the mounting head 9 that are movably provided independently of the mounting head 9 pick up the component P from the component supply unit 15. The recognition camera control means (control device 21) for recognizing the component mounting position L by the recognition camera 19 is provided while the mounting head 9 supplies the components. While the component P is picked up from the part 15, the recognition of the component mounting position L is performed by the recognition camera 19 provided so as to be movable independently of the mounting head 9.

このように、本実施の形態における部品実装機1(部品実装方法)では、搭載ヘッド9が部品供給部15より部品Pをピックアップしている間(ステップST4の部品ピックアップ工程及びその前後)に、搭載ヘッド9とは独立して移動自在に設けられた認識カメラ19によって部品搭載位置Lの認識を行うようになっているので、認識カメラ19による部品搭載位置Lの検査(認識)を、搭載ヘッド9による部品搭載と並行して行うことができる。このため、部品搭載位置Lの検査(ここでは前検査)を行いながら部品Pの搭載を実行でき、生産効率を大幅に向上させることができる。   Thus, in the component mounting machine 1 (component mounting method) in the present embodiment, while the mounting head 9 is picking up the component P from the component supply unit 15 (the component pickup process in step ST4 and before and after). Since the component mounting position L is recognized by a recognition camera 19 that is movably provided independently of the mounting head 9, the inspection (recognition) of the component mounting position L by the recognition camera 19 is performed on the mounting head. 9 can be performed in parallel with component mounting. For this reason, the mounting of the component P can be executed while performing the inspection of the component mounting position L (here, the previous inspection), and the production efficiency can be greatly improved.

また、本実施の形態における部品実装機1(及び部品実装方法)では、認識カメラ19による部品搭載位置Lの認識が、認識カメラ19がまだ認識していない部品搭載位置Lの中から、搭載ヘッド9により部品Pが搭載される順番の最も早いものを抽出し、その抽出した部品搭載位置Lを含む一又は複数の部品搭載位置Lを認識対象として行うようになっているので、認識カメラ19による部品搭載位置Lの検査(認識)を、搭載ヘッド9による部品搭載順序を基準とした順序で行うことができ、他の部品搭載位置Lについての検査を先取りして行うこともできる(図8を用いて示した例参照)。このため、上述の実施の
形態の場合のように、認識カメラ19が前検査を行うものであれば、搭載ヘッド9が部品Pを部品搭載位置Lに搭載する前にその部品搭載位置Lの検査を終わらせておくことができ、効率のよい部品実装を行うことが可能である。
In the component mounter 1 (and component mounting method) according to the present embodiment, the recognition of the component mounting position L by the recognition camera 19 is performed from the component mounting positions L that the recognition camera 19 has not yet recognized. 9 is used to extract the component in the earliest order in which components P are mounted, and one or a plurality of component mounting positions L including the extracted component mounting positions L are used as recognition targets. The inspection (recognition) of the component mounting position L can be performed in the order based on the component mounting order by the mounting head 9, and the inspection for other component mounting positions L can be performed in advance (see FIG. 8). See example shown). For this reason, as in the case of the above-described embodiment, if the recognition camera 19 performs a pre-inspection, the mounting head 9 inspects the component mounting position L before mounting the component P at the component mounting position L. Thus, efficient component mounting can be performed.

これまで本発明の実施の形態について説明してきたが、本発明は上述の実施の形態に示したものに限定されない。例えば、上述の実施の形態では、認識カメラ19による部品搭載位置Lの認識は、搭載ヘッド9によりその部品搭載位置Lに部品Pを搭載する前に行うものであり、これから基板3上に搭載しようとする部品Pを部品搭載位置Lに搭載することができるかどうか等を検査(前検査)するものであったが、これとは反対に、認識カメラ19による部品搭載位置Lの認識を、搭載ヘッド9により部品Pが搭載された後に行うようにし、搭載ヘッド9により部品Pを搭載した後の部品搭載位置Lの状態が正常であるかどうか等を検査(後検査。例えば、搭載ヘッド9により搭載した部品Pが正しく搭載されているかを検査)するものであってもよい。或いは、認識カメラ19により、部品Pの搭載前と搭載後の両方において、部品搭載位置Lの認識を行うようにしてもよい。   Although the embodiments of the present invention have been described so far, the present invention is not limited to those shown in the above-described embodiments. For example, in the above-described embodiment, the recognition of the component mounting position L by the recognition camera 19 is performed before the mounting of the component P at the component mounting position L by the mounting head 9, and it will be mounted on the board 3 from now on. The component P to be inspected (pre-inspection) whether or not the component P can be mounted on the component mounting position L, on the contrary, the recognition of the component mounting position L by the recognition camera 19 is mounted. This is performed after the component P is mounted by the head 9, and the component mounting position L after the component P is mounted by the mounting head 9 is inspected for normality (post-inspection. For example, by the mounting head 9 It is also possible to inspect whether or not the mounted component P is correctly mounted. Alternatively, the component mounting position L may be recognized by the recognition camera 19 both before and after the component P is mounted.

このように認識カメラ19が後検査を行う場合にも、搭載ヘッド9が部品供給部15より部品Pをピックアップしている間に、搭載ヘッド9とは独立して移動自在な認識カメラ19が部品搭載位置Lの認識を行うことになるので、認識カメラ19による検査を、搭載ヘッド9による部品搭載と並行して行うことができる。このため、上述の実施の形態の場合と同様、部品搭載位置Lの検査(後検査)を行いながら部品Pの搭載を実行でき、生産効率を大幅に向上させることができる。   As described above, even when the recognition camera 19 performs the post-inspection, the recognition camera 19 that is movable independently of the mounting head 9 is capable of moving while the mounting head 9 picks up the component P from the component supply unit 15. Since the mounting position L is recognized, the inspection by the recognition camera 19 can be performed in parallel with the component mounting by the mounting head 9. For this reason, as in the case of the above-described embodiment, mounting of the component P can be executed while performing the inspection (post-inspection) of the component mounting position L, and the production efficiency can be greatly improved.

また、このように後検査を行う場合、認識カメラ19による部品搭載位置Lの認識が、認識カメラ19がまだ認識していない部品搭載位置Lの中から、搭載ヘッド9により部品Pが搭載される順番の最も早いものを抽出し、その抽出した部品搭載位置Lを含む一又は複数の部品搭載位置Lを認識対象として行われるようにすることにより、後検査を搭載ヘッド9による部品搭載順序を基準とした順序で行うことができ、後検査を搭載ヘッド9による部品搭載に追従して(部品Pごと、基板3への搭載の直後に)行わせることができるので、搭載ヘッド9が部品Pの搭載を終了するのとほぼ同時に後検査を終了させるようにすることが可能である。   When the post-inspection is performed in this way, the component mounting position L is recognized by the recognition camera 19, and the component P is mounted by the mounting head 9 from the component mounting positions L that the recognition camera 19 has not yet recognized. The one with the earliest order is extracted, and one or a plurality of component mounting positions L including the extracted component mounting positions L are performed as recognition targets, so that the post-inspection is based on the component mounting order by the mounting head 9 The post-inspection can be performed following the component mounting by the mounting head 9 (with each component P immediately after mounting on the substrate 3). It is possible to end the post-inspection almost simultaneously with the end of the mounting.

また、この部品実装機1では、認識カメラ19を用いて前検査と後工程の双方を行うこともできる。すなわち、基板3を搬入した後、部品搭載位置Lについての前検査を実行しつつ搭載ヘッド9による部品搭載を行い、全ての部品搭載位置Lについての前検査が終了し次第、部品搭載が終了した部品搭載位置Lの後検査を行うようにする。このように1つの部品実装機1で前検査、部品搭載及び後検査を行うようにすることにより、生産効率を向上させることができるのみならず、部品実装ラインにおける装置の台数を減らすことができるので、大幅なコストダウンを図ることができる。   In the component mounter 1, both the pre-inspection and the post-process can be performed using the recognition camera 19. That is, after the board 3 is carried in, component mounting is performed by the mounting head 9 while performing the pre-inspection for the component mounting position L, and the component mounting is completed as soon as the pre-inspection for all the component mounting positions L is completed. A post-inspection is performed after the component mounting position L. Thus, by performing the pre-inspection, component mounting and post-inspection with one component mounting machine 1, not only can the production efficiency be improved, but also the number of devices in the component mounting line can be reduced. Therefore, significant cost reduction can be achieved.

部品搭載位置の検査(前検査又は後検査)を行いながら部品の搭載を実行できるようにして生産効率を向上させることができる部品実装機及び部品実装方法を提供する。   Provided is a component mounting machine and a component mounting method capable of improving the production efficiency by allowing component mounting to be performed while inspecting the component mounting position (pre-inspection or post-inspection).
