基板生産システム及び基板作業機の検査方法Board production system and board working machine inspection method
　本明細書に開示する技術は、基板生産システム及び基板作業機の検査方法に関する。 The technology disclosed in this specification relates to a board production system and a board working machine inspection method.
　例えば、国際公開第２０１８／０７３９５２号公報には、基板を生産するための作業を実行する基板作業機が開示されている。一般的に、基板作業機では、基板作業機に設けられる各部に対して定期的にメンテナンスが必要となる。メンテナンスの一例としては、フィルタの清掃や交換が挙げられる。基板作業機は、基板作業機の内部に空気を導入したり、基板作業機内に導入された空気を排出したりするためのファンを有しており、ファンには、フィルタが設けられている。フィルタによって、基板作業機の内部に塵や埃等の侵入が抑制される。基板作業機を使用すると、フィルタに塵や埃が堆積する。このため、定期的にフィルタのメンテナンスが必要となる。このような基板作業機の各部のメンテナンスのタイミングは、作業者が各部の状態を確認することによって決定している。 For example, International Publication No. 2018/073952 discloses a board working machine that performs work for producing boards. In general, the board working machine requires periodic maintenance of each part provided in the board working machine. An example of maintenance includes cleaning and replacement of filters. The board working machine has a fan for introducing air into the board working machine and discharging the air introduced into the board working machine, and the fan is provided with a filter. The filter prevents dust, dirt, and the like from entering the inside of the board working machine. Dirt and dust accumulate on the filter when using the board working machine. For this reason, regular maintenance of the filter is required. The maintenance timing of each part of such a board working machine is determined by an operator checking the state of each part.
　基板作業機の各部位のメンテナンスのタイミングは、基板作業機の使用環境等によって変化する。しかしながら、基板作業機のメンテナンスが必要な部位は、作業者が目視等で確認し難い位置に設けられていることがあり、また、作業者がメンテナンスが必要な部位に近づき難いことがある。この場合、作業者は、基板作業機のメンテナンスが必要な部位の状態を確認することが難しい。また、メンテナンスが必要な部位を作業者が確認可能な場合であっても、その部位の状態が、メンテナンスすべき状態であるのか、メンテナンス不要な状態であるのかを、作業者が判断することが難しいこともある。 The timing of maintenance for each part of the board working machine changes depending on the usage environment of the board working machine. However, the parts of the board working machine that require maintenance are sometimes provided in positions that are difficult for the operator to visually confirm, and it is also difficult for the operator to approach the parts that require maintenance. In this case, it is difficult for the operator to check the state of the parts of the board working machine that require maintenance. In addition, even if the operator can check the part that requires maintenance, the operator cannot determine whether the part requires maintenance or does not require maintenance. It can be difficult.
　本明細書は、基板作業機のメンテナンスの有無を適切に判断するための技術を開示する。 This specification discloses a technique for appropriately determining whether or not there is maintenance for a board working machine.
　本明細書に開示する基板生産システムは、所定の設定エリアに設置され、基板に作業を行う複数台の基板作業機と、設定エリア内を移動可能とされ、複数台の基板作業機の少なくとも一台に対して所定の検査作業を行う検査部と、検査部による検査結果を送信する第１通信部と、を備える移動体と、第１通信部から送信される検査結果を受信する第２通信部と、第２通信部で受信した検査結果を出力する出力部と、を備える管理装置と、を備える。 The board production system disclosed in the present specification includes a plurality of board working machines that are installed in a predetermined setting area and work on boards, and at least one of the plurality of board working machines that is movable within the set area. A moving body including an inspection unit that performs predetermined inspection work on a table, a first communication unit that transmits inspection results from the inspection unit, and a second communication unit that receives the inspection results transmitted from the first communication unit. and an output unit configured to output the test result received by the second communication unit.
　上記の基板生産システムでは、移動体を用いて検査作業が実行される。また、移動体を用いて実行された検査作業の検査結果は、管理装置に送信される。これにより、作業者が、検査作業や、検査結果からメンテナンスの有無を判断する作業を実行する必要がなくなり、管理装置側で基板作業機のメンテナンスの有無を適切に判断することが可能となる。 In the board production system described above, inspection work is performed using a moving body. Moreover, the inspection result of the inspection work performed using the mobile body is transmitted to the management device. This eliminates the need for the operator to perform the inspection work and the work of determining whether or not maintenance is required based on the inspection results, and the management device can appropriately determine whether or not the board working machine needs maintenance.
　また、本明細書に開示する基板作業機の検査方法は、基板に作業を行う複数台の基板作業機の少なくとも一台の基板作業機を検査する方法である。検査方法は、複数台の基板作業機が設置された設定エリア内の所定の位置に移動体を配置する工程と、所定の位置に配置された移動体を、複数台の基板作業機のうち検査対象となる基板作業機に対して位置決めする位置決め工程と、位置決めされた移動体によって、検査対象となる基板作業機に対して所定の検査作業を実施する検査工程と、検査工程により得られた検査結果を管理装置に送信する送信工程と、を備える。 Also, the method for inspecting a board working machine disclosed in this specification is a method for inspecting at least one board working machine among a plurality of board working machines that work on a board. The inspection method includes a step of placing a moving body at a predetermined position in a set area in which a plurality of board working machines are installed, and inspecting the moving body placed at the predetermined position among the plurality of board working machines. A positioning process for positioning a board working machine to be inspected, an inspection process for performing a predetermined inspection work on the board working machine to be inspected by the positioned moving body, and an inspection obtained by the inspection process. and a sending step of sending the result to the management device.

　本明細書に開示する基板生産システムは、所定の設定エリア内を移動可能な移動体を備えている。例えば、基板作業機の背面側等の場所には、作業者は立ち入り難いことがある。一方、移動体であれば、作業者が立ち入り難い場所にも移動可能となる。このため、移動体を用いることによって、作業者が直接確認し難い位置にある基板作業機の検査を適切に行うことができる。また、移動体は、検査部により実行された検査結果を、管理装置に送信する。これにより、管理装置側で検査結果を確認することができ、管理装置側で基板作業機のメンテナンスの有無を判断可能となる。このため、作業者の負担を低減できると共に、基板作業機を適切なタイミングでメンテナンスすることができる。 The board production system disclosed in this specification includes a movable body that can move within a predetermined set area. For example, it may be difficult for workers to enter places such as the back side of the board working machine. On the other hand, if it is a mobile body, it can be moved to a place where it is difficult for workers to enter. Therefore, by using the moving body, it is possible to appropriately inspect the board working machine located at a position that is difficult for the operator to directly check. In addition, the mobile body transmits the inspection result executed by the inspection unit to the management device. As a result, the inspection result can be confirmed on the side of the management device, and the presence or absence of maintenance of the board working machine can be determined on the side of the management device. Therefore, the burden on the operator can be reduced, and the substrate working machine can be maintained at an appropriate timing.

The inspection result may be an image of the filter taken by the camera. According to such a configuration, the management device acquires the image of the filter provided on the board working machine. As a result, it is possible to appropriately determine whether or not maintenance of the filter provided in the substrate working machine is required on the management device side.
　本明細書が開示する基板生産システムでは、空気取込口は、ハウジングの背面、上面又は側面に設けられていてもよい。移動体は、設定エリア内を飛行する飛行体であってもよい。このような構成によると、移動体が飛行することによって、カメラは、ハウジングの背面、上面又は側面の画像を撮影できる。ハウジングの背面、上面又は側面は、作業者によって確認し難いことがある。このため、作業者が確認し難い位置にあるフィルタの状態を適切に検査することができる。 In the board production system disclosed in this specification, the air inlet may be provided on the rear surface, top surface, or side surface of the housing. The mobile object may be an aircraft that flies within the set area. According to such a configuration, the camera can take an image of the rear surface, top surface, or side surface of the housing as the moving object flies. The back, top or sides of the housing can be difficult to see by the operator. Therefore, it is possible to appropriately inspect the state of the filter located at a position that is difficult for the operator to check.

The second communication unit may transmit the control command input from the input unit to the first communication unit. The moving body may further include a driving section for moving the moving body, and a control section for controlling the driving section based on the control command received by the first communication section. According to such a configuration, the operator can operate the moving body from the management device. This allows the operator to appropriately perform the inspection work via the moving body.

The inspection result may be an audio signal obtained by converting the sound generated from the board working part into an electrical signal. According to such a configuration, the management device acquires the audio signal obtained by converting the sound generated from the board working machine into an electric signal. For example, when an abnormality occurs in a device (for example, an air device, a motor, etc.) provided in the board working machine, an abnormal noise is generated. Acquisition of the audio signal by the management device makes it possible to appropriately determine whether or not there is maintenance (whether or not there is an abnormal noise) in the devices provided in the board working machine.

The board conveyor 20 carries in, supports and carries out the circuit board 2 .
　タッチパネル２４は、作業者に部品実装機１０の各種の情報を提供する表示装置であるとともに、作業者からの指示や情報を受け付ける入力装置である。制御装置２６は、ＣＰＵ及び記憶装置を備えるコンピュータを用いて構成されている。制御装置２６は、部品実装機１０の各部を制御している。タッチパネル２４は、ハウジング２８の前面側（－Ｙ方向側）に設置されており、制御装置２６は、ハウジング２８の背面側（＋Ｙ方向側）に設置されている。部品実装機１０は、設定エリア６０内において、作業者がハウジング２８の前面側にアクセスし易くなるように設置される。以下では、ハウジング２８の側面のうち、タッチパネル２４が設置される面をハウジング２８の前面と称し、ハウジング２８の前面とは反対側をハウジング２８の背面と称し、その他の側面を単にハウジング２８の側面と称することがある。 The touch panel 24 is a display device that provides various types of information about the component mounter 10 to the operator, and is an input device that receives instructions and information from the operator.

A plurality of propellers are rotated by driving the drive unit 52, and the drone 50 flies. Also, by individually controlling the number of rotations of a plurality of propellers, the drone 50 can be moved to a desired height and direction. Note that the drone 50 is equipped with various sensors (eg, a gyro sensor, an acceleration sensor, an altitude sensor, a distance sensor, etc.).

Specifically, the multiple light sources are a front light source and a side light source. The front light source is installed so as to illuminate the object to be photographed coaxially with the photographing direction of the camera. The side light source is installed so as to illuminate the object to be photographed obliquely with respect to the photographing direction of the camera.

The communication unit 56 transmits an image captured by the imaging device 54 (for example, a captured image of the filter 32 of the mounter 10 ) to the communication unit 74 . The communication unit 56 also receives a control command (described later) for the drone 50 transmitted from the communication unit 74 . The communication unit 56 outputs the received control command to the control unit 58 .

The control unit 58 is connected to the driving unit 52, the photographing device 54 and the communication unit 56, and controls the driving unit 52, the photographing device 54 and the communication unit 56 respectively. Specifically, the control unit 58 controls the drive unit 52 based on the control command received by the communication unit 56 . The control unit 58 also causes the communication unit 56 to transmit the image captured by the imaging device 54 to the communication unit 74 of the management device 70 .

Note that the input unit 72 is not particularly limited as long as it can input a control command for controlling the drone 50 . A control command input to the input unit 72 is output to the control unit 78 .
　通信部７４は、インターネット１００を介してドローン５０の通信部５６と通信することができる。通信部７４は、入力部７２に入力されたドローン５０の制御指令を通信部５６に送信する。また、通信部７４は、通信部５６から送信された撮影画像を受信する。通信部７４は、受信した撮影画像を制御部７８に出力する。 The communication unit 74 can communicate with the communication unit 56 of the drone 50 via the Internet 100. The communication unit 74 transmits the control command for the drone 50 input to the input unit 72 to the communication unit 56 . The communication unit 74 also receives the captured image transmitted from the communication unit 56 . The communication unit 74 outputs the received captured image to the control unit 78 .
　ディスプレイ７６は、制御部７８から出力された画像を表示する。具体的には、ディスプレイ７６は、通信部７４を介して受信したドローン５０の撮影装置５４による撮影画像を表示する。 The display 76 displays images output from the control unit 78 . Specifically, the display 76 displays an image captured by the imaging device 54 of the drone 50 received via the communication unit 74 .
　制御部７８は、ＣＰＵ及び記憶装置を備えるコンピュータを用いて構成されている。制御部７８は、入力部７２、通信部７４及びディスプレイ７６に接続しており、入力部７２、通信部７４及びディスプレイ７６をそれぞれ制御している。具体的には、制御部７８は、入力部７２に入力されたドローン５０の制御指令を、通信部７４から部品実装機１０の通信部５６に送信させる。また、制御部７８は、通信部７４が受信した撮影画像をディスプレイ７６に表示させる。 The control unit 78 is configured using a computer having a CPU and a storage device. The control unit 78 is connected to the input unit 72, the communication unit 74, and the display 76, and controls the input unit 72, the communication unit 74, and the display 76, respectively. Specifically, the control unit 78 causes the communication unit 74 to transmit the control command for the drone 50 input to the input unit 72 to the communication unit 56 of the mounter 10 . Further, the control unit 78 causes the display 76 to display the captured image received by the communication unit 74 .
　次に、本実施例の基板生産システム１を用いて部品実装機１０のフィルタ３２を検査する方法について説明する。フィルタ３２は、吸気ファン３０により部品実装機１０内に導入される空気から塵や埃等を除去する。したがって、部品実装機１０の使用に伴い、フィルタ３２には徐々に塵や埃等が堆積する。フィルタ３２に堆積する塵や埃等の量が過多となると、フィルタ３２が目詰まりする。このため、フィルタ３２は、適切なタイミングで清掃や交換等のメンテナンスを行う必要がある。しかしながら、フィルタ３２は、部品実装機１０のハウジング２８の背面に設置されている（図２参照）。部品実装機１０は、作業者が部品実装機１０の背面側に接近し難いように設置されていることが多い。このため、作業者がフィルタ３２を確認するためには、部品実装機１０の背面を目視できるように部品実装機１０を移動させる（例えば、部品実装機１０を前方に引き出す）必要がある。また、作業者によっては、フィルタ３２を目視で確認しても、フィルタ３２のメンテナンスが必要か否かを判断することが難しい場合がある。以下に、フィルタ３２をメンテナンスすべきか否かを適切に検査する方法について説明する。 Next, a method for inspecting the filter 32 of the mounter 10 using the board production system 1 of this embodiment will be described. The filter 32 removes dust, dirt, and the like from the air introduced into the mounter 10 by the intake fan 30 . Therefore, as the mounter 10 is used, dust and dirt gradually accumulate on the filter 32 . When the amount of dirt, dust, etc. accumulated on the filter 32 becomes excessive, the filter 32 will be clogged. Therefore, it is necessary to perform maintenance such as cleaning and replacement of the filter 32 at appropriate timing. However, the filter 32 is installed on the rear surface of the housing 28 of the mounter 10 (see FIG. 2). The component mounter 10 is often installed so that it is difficult for an operator to approach the rear side of the component mounter 10 . Therefore, in order for the operator to check the filter 32, it is necessary to move the component mounter 10 (for example, pull out the component mounter 10 forward) so that the rear surface of the component mounter 10 can be seen. Further, it may be difficult for some workers to determine whether or not maintenance of the filter 32 is necessary even by visually checking the filter 32 . A method for appropriately inspecting whether the filter 32 should be maintained will be described below.
　まず、設定エリア６０内にいる作業者（以下、単に「作業者」ともいう）は、設定エリア６０内の所定の位置（例えば、複数の部品実装機１０のうちの１つの部品実装機１０の背面の近傍）にドローン５０を載置し、ドローン５０の電源スイッチ（図示省略）をオンにする。すると、ドローン５０と管理装置７０との通信を確立すると共に、ドローン５０は、撮影装置５４による撮影を開始する。撮影装置５４で撮影された撮影画像は、通信部５６を介して管理装置７０の通信部７４に随時送信される。 First, a worker in the setting area 60 (hereinafter also simply referred to as “worker”) moves to a predetermined position in the setting area 60 (for example, one mounter 10 out of the plurality of mounters 10). The drone 50 is placed on the back surface), and the power switch (not shown) of the drone 50 is turned on. Then, communication between the drone 50 and the management device 70 is established, and the drone 50 starts photographing by the photographing device 54 . A photographed image photographed by the photographing device 54 is transmitted to the communication section 74 of the management device 70 via the communication section 56 as needed.
　管理装置７０がドローン５０からの撮影画像を受信すると、管理装置７０が設置されている場所にいるオペレータ（以下、単に「オペレータ」ともいう）が、撮影画像を確認しながらドローン５０を操作する。具体的には、オペレータは、入力部７２を介してドローン５０の制御指令を入力する。入力部７２に入力された制御指令は、通信部７４からドローン５０の通信部５６に送信される。ドローン５０の制御部５８は、受信した制御指令に従い駆動部５２を制御する。これにより、ドローン５０は、オペレータの操作に従い移動する。 When the management device 70 receives the captured image from the drone 50, an operator (hereinafter simply referred to as "operator") at the location where the management device 70 is installed operates the drone 50 while checking the captured image. Specifically, the operator inputs a control command for the drone 50 via the input unit 72 . The control command input to the input unit 72 is transmitted from the communication unit 74 to the communication unit 56 of the drone 50 . The control unit 58 of the drone 50 controls the drive unit 52 according to the received control command. Thereby, the drone 50 moves according to the operator's operation.
　オペレータは、撮影画像を確認しながら、ドローン５０を所定の位置まで移動させる。具体的には、オペレータは、ドローン５０の撮影装置５４が、検査対象となる複数の部品実装機１０のうちの１つの部品実装機１０（すなわち、１番目の部品実装機１０）のフィルタ３２を撮影可能な位置に、ドローン５０を移動させる。なお、ドローン５０及び管理装置７０は、図示しない音声通信機能をそれぞれ備えていてもよく、オペレータは、設定エリア６０内の作業者と連絡を取りながらドローン５０を移動させてもよい。具体的には、オペレータは、ドローン５０の侵入経路に障害物があったり、他の作業者がいたりしないことを作業者に確認しながら、ドローン５０を操縦してもよい。また、ドローン５０は、報知部（図示省略）を備えていてもよい。報知部は、ドローン５０が飛行していることを周囲に報知可能な構成であればよく、例えば、サイレンであってもよいし、音声発生装置であってもよい。ドローン５０を移動させる際に、報知部でドローン５０が飛行していることをドローン５０の周囲に報知することによって、他の作業者がドローン５０に接触する等の危険を回避することができる。 The operator moves the drone 50 to a predetermined position while checking the captured image. Specifically, the operator uses the imaging device 54 of the drone 50 to capture the filter 32 of one mounter 10 (that is, the first mounter 10) among the plurality of mounters 10 to be inspected. Move the drone 50 to a position where photography is possible. Note that the drone 50 and the management device 70 may each have a voice communication function (not shown), and the operator may move the drone 50 while communicating with workers in the setting area 60 . Specifically, the operator may operate the drone 50 while confirming with the worker that there are no obstacles or other workers in the entry path of the drone 50 . Also, the drone 50 may include a notification unit (not shown). The notification unit may be configured to notify the surroundings that the drone 50 is flying, and may be, for example, a siren or an audio generator. When moving the drone 50, by notifying the surroundings of the drone 50 that the drone 50 is flying with the notification unit, danger such as contacting the drone 50 by other workers can be avoided.
　ドローン５０が１番目の部品実装機１０のフィルタ３２を撮影可能な位置まで移動すると、オペレータは、入力部７２を介して撮影装置５４でフィルタ３２を撮影する。フィルタ３２を撮影する際には、まず、正面光源でフィルタ３２を照明した状態でフィルタ３２を撮影する。ただし、正面光源でフィルタ３２を照明して撮影した画像では、フィルタ３２の陰影が鮮明ではなく、フィルタ３２の状態を判定し難いとオペレータが判断した場合、オペレータは、側射光源でフィルタ３２を照明した状態でフィルタ３２を撮影するように入力部７２に制御指令を入力する。部品実装機１０の設置位置や設定エリア６０内の照明の設置位置等の条件によって、フィルタ３２を正面光源で照明したほうがフィルタ３２を鮮明に撮影できる場合もあれば、フィルタ３２を側射光源で照明したほうがフィルタ３２を鮮明に撮影できる場合もある。オペレータは、撮影画像を確認しながら、フィルタ３２の状態を判定するために最も適した撮影画像となるように、フィルタ３２への照明を調整する。撮影されたフィルタ３２の撮影画像は、管理装置７０の制御部７８のメモリ（図示省略）に記憶される。撮影画像は、ドローン５０によって撮影される。ドローン５０は、作業者が侵入できない場所にも侵入可能である。このため、部品実装機１０の設置位置を変えることなく、部品実装機１０の背面側に設置されるフィルタ３２の状態を確認できる。 When the drone 50 moves to a position where the filter 32 of the first mounter 10 can be photographed, the operator photographs the filter 32 with the photographing device 54 via the input unit 72 . When photographing the filter 32, first, the filter 32 is photographed with the filter 32 illuminated by a front light source. However, if the operator judges that it is difficult to determine the state of the filter 32 because the shadow of the filter 32 is not clear in the image captured by illuminating the filter 32 with the front light source, the operator may illuminate the filter 32 with the side light source. A control command is input to the input unit 72 so as to photograph the filter 32 in an illuminated state. Depending on conditions such as the installation position of the component mounter 10 and the installation position of the lighting within the setting area 60, there are cases where the filter 32 can be photographed more clearly by illuminating the filter 32 with a front light source, whereas there are cases where the filter 32 can be photographed clearly by illuminating the filter 32 with a side illumination light source. In some cases, the filter 32 can be photographed more clearly with illumination. While checking the captured image, the operator adjusts the illumination of the filter 32 so that the captured image is most suitable for judging the state of the filter 32 . The photographed image of the filter 32 is stored in a memory (not shown) of the control unit 78 of the management device 70 . A captured image is captured by the drone 50 . The drone 50 can also enter places where workers cannot enter. Therefore, the state of the filter 32 installed on the back side of the component mounter 10 can be checked without changing the installation position of the component mounter 10 .
　フィルタ３２の撮像画像が記憶されると、オペレータとは異なる別の判定者（以下、単に「判定者」ともいう）が、撮影画像からフィルタ３２の状態を判定する。なお、オペレータがフィルタ３２の状態を判定可能である場合には、フィルタ３２の状態は、オペレータが判定してもよい。作業者によっては、フィルタ３２が、メンテナンスが必要な状態であるか否かを正確に判断できないことがある。判定者（又は判定能力を有するオペレータ）によってフィルタ３２の状態を判定することによって、フィルタ３２の状態を適切に判定することができる。 When the captured image of the filter 32 is stored, another determiner (hereinafter simply referred to as "determiner") who is different from the operator determines the state of the filter 32 from the captured image. If the operator can determine the state of the filter 32 , the operator may determine the state of the filter 32 . Depending on the operator, it may not be possible to accurately determine whether the filter 32 requires maintenance. The state of the filter 32 can be appropriately determined by the state of the filter 32 being determined by a determiner (or an operator having determination ability).
　１番目の部品実装機１０のフィルタ３２の撮影が終了すると、オペレータは、設定エリア６０内の別の部品実装機１０（すなわち、２番目の部品実装機１０）のフィルタ３２を撮影する。なお、２番目の部品実装機１０のフィルタ３２の撮影方法は、１番目の部品実装機１０のフィルタ３２の撮影方法と同様であるため、詳細な説明は省略する。同様にして、設定エリア６０内の検査対象となっている全ての部品実装機１０のフィルタ３２を撮影する。なお、排気ファン３４にもフィルタが取り付けられている場合には、排気ファン３４に取り付けられているフィルタも撮影する。撮影されたフィルタ３２の撮影画像は、管理装置７０に送信される。判定者は、送信された撮影画像から各フィルタ３２の状態を判定する。なお、本実施例では、撮影画像は、ディスプレイ７６に表示されるが、このような構成に限定されない。判定者が撮影画像を確認できればよく、例えば、撮影画像は、印刷装置等によって紙等に印刷されてもよい。 After completing the imaging of the filter 32 of the first mounter 10 , the operator images the filter 32 of another mounter 10 (that is, the second mounter 10 ) within the setting area 60 . The method of photographing the filter 32 of the second mounter 10 is the same as the method of photographing the filter 32 of the first mounter 10, and thus detailed description thereof will be omitted. Similarly, the filters 32 of all the component mounters 10 to be inspected within the setting area 60 are photographed. If a filter is also attached to the exhaust fan 34, the filter attached to the exhaust fan 34 is also photographed. The photographed image of the filter 32 that has been photographed is transmitted to the management device 70 . The judge judges the state of each filter 32 from the transmitted photographed image. Note that in this embodiment, the captured image is displayed on the display 76, but the configuration is not limited to this. As long as the judge can confirm the captured image, the captured image may be printed on paper or the like by a printing device or the like.
　フィルタ３２についての判定結果は、作業者に報告される。例えば、フィルタ３２の状態が悪く、目詰まりしている場合には、直ちにメンテナンスが必要である旨が報告される。また、直ちにメンテナンスを行う必要がある状態まではいかないが、部分的に目詰まりしている場合等には、目詰まりしている程度に応じていつメンテナンスすべきかを報告する。例えば、別の部位のメンテナンスの際に併せてフィルタ３２のメンテナンスも実施することを推奨してもよい。また、メンテナンスする旨を報告した場合には、メンテナンスの終了後に、メンテナンス後のフィルタ３２をドローン５０で撮影し、オペレータがメンテナンス後のフィルタ３２の状態を確認してもよい。 The determination result of the filter 32 is reported to the operator. For example, if the filter 32 is in poor condition and is clogged, it is immediately reported that maintenance is required. In addition, although it does not reach a state where immediate maintenance is required, if there is partial clogging, etc., it reports when maintenance should be performed according to the degree of clogging. For example, it may be recommended to perform maintenance on the filter 32 together with maintenance on another part. Further, when the maintenance is reported, after the maintenance is completed, the operator may check the state of the filter 32 after maintenance by photographing the filter 32 after maintenance with the drone 50 .
　なお、本実施例では、吸気ファン３０及びフィルタ３２は、部品実装機１０のハウジング２８の背面に設けられていたが、このような構成に限定されない。例えば、吸気ファン及びフィルタは、ハウジング２８の上面や側面に設けられていてもよい。この場合、ドローン５０を用いて上面や側面に設けられるフィルタを撮影すれば、本実施例と同様にフィルタの状態を適切に判定することができる。 Although the intake fan 30 and the filter 32 are provided on the rear surface of the housing 28 of the component mounter 10 in this embodiment, the configuration is not limited to this. For example, the intake fan and filter may be provided on the top or side of the housing 28 . In this case, if the drone 50 is used to photograph the filters provided on the top surface and side surfaces, the state of the filters can be determined appropriately as in the present embodiment.
　また、本実施例では、判定者が部品実装機１０の状態（具体的には、フィルタ３２の状態）を判定したが、このような構成に限定されない。部品実装機１０の状態は、管理装置７０の制御部７８が自動で判定してもよい。例えば、制御部７８は、初期状態（使用前の状態）のフィルタ３２を撮影した撮影画像を記憶しており、初期状態のフィルタ３２の撮影画像と、ドローン５０の撮影装置５４で撮影したフィルタ３２の撮影画像を比較して、フィルタ３２の状態を判定することができる。具体的には、制御部７８は、初期状態のフィルタ３２の撮影画像と、撮影装置５４で撮影したフィルタ３２の撮影画像との間の差分を演算し、差分が所定値より大きいときにメンテナンスが必要であると判定してもよい。 Also, in this embodiment, the determiner determined the state of the mounter 10 (specifically, the state of the filter 32), but the configuration is not limited to this. The state of the mounter 10 may be determined automatically by the control unit 78 of the management device 70 . For example, the control unit 78 stores a photographed image of the filter 32 in the initial state (state before use). can be compared to determine the state of the filter 32 . Specifically, the control unit 78 calculates the difference between the captured image of the filter 32 in the initial state and the captured image of the filter 32 captured by the imaging device 54, and when the difference is greater than a predetermined value, maintenance is required. may be determined to be necessary.
　また、本実施例では、部品実装機１０のフィルタ３２の状態を検査しているが、このような構成に限定されない。撮影画像から検査を実施できる部位であれば、本実施例と同様にドローン５０を用いて検査を実施することができる。 Also, in this embodiment, the state of the filter 32 of the mounter 10 is inspected, but the configuration is not limited to this. As long as the part can be inspected from the captured image, the inspection can be performed using the drone 50 in the same manner as in the present embodiment.
（実施例２）
　上記の実施例１では、部品実装機１０に設置されるフィルタ３２の状態を検査したが、このような構成に限定されない。例えば、ドローン等の移動体を用いて、部品実装機１０から発生する音を検査してもよい。 (Example 2)
Although the state of the filter 32 installed in the mounter 10 is inspected in the first embodiment, the configuration is not limited to this. For example, a moving object such as a drone may be used to inspect the sound generated from the mounter 10 .
　図５に示すように、本実施例のドローン１５０は、駆動部５２と、マイク１５４と、通信部５６と、制御部５８を備えている。なお、駆動部５２、通信部５６及び制御部５８は、上記の実施例１の駆動部５２、通信部５６及び制御部５８と同様の構成であるため、詳細な説明は省略する。 As shown in FIG. 5, the drone 150 of this embodiment includes a drive section 52, a microphone 154, a communication section 56, and a control section 58. The drive unit 52, the communication unit 56, and the control unit 58 have the same configurations as the drive unit 52, the communication unit 56, and the control unit 58 of the first embodiment, and detailed description thereof will be omitted.
　マイク１５４は、部品実装機１０から発生する音を電気信号に変換する。また、ドローン１５０は、ノイズキャンセリング用の収音マイク（図示省略）を備えている。マイク１５４から出力される音声信号からドローン１５０の駆動部５２の駆動音をノイズキャンセリング機能によって消すことで、マイク１５４から出力される音声信号は、部品実装機１０から発生する音（駆動部５２の駆動音を除いた音）を電気信号に変換したものとなる。マイク１５４から出力される音声信号は、通信部５６を介して管理装置１７０に送信される。 A microphone 154 converts the sound generated from the component mounter 10 into an electric signal. The drone 150 also includes a sound pickup microphone (not shown) for noise canceling. By eliminating the driving sound of the driving unit 52 of the drone 150 from the audio signal output from the microphone 154 by using the noise canceling function, the audio signal output from the microphone 154 is the sound generated from the mounter 10 (the driving unit 52 The sound excluding the driving sound of the motor) is converted into an electric signal. An audio signal output from the microphone 154 is transmitted to the management device 170 via the communication unit 56 .
　図６に示すように、本実施例の管理装置７０は、入力部７２と、通信部７４と、スピーカ１７６と、制御部７８を備えている。なお、入力部７２、通信部７４及び制御部７８は、上記の実施例１の入力部７２、通信部７４及び制御部７８と同様の構成であるため、詳細な説明は省略する。 As shown in FIG. 6, the management device 70 of this embodiment includes an input unit 72, a communication unit 74, a speaker 176, and a control unit 78. The input unit 72, the communication unit 74, and the control unit 78 have the same configurations as the input unit 72, the communication unit 74, and the control unit 78 of the first embodiment described above, so detailed description thereof will be omitted.
　スピーカ１７６は、通信部７４がドローン１５０の通信部５６から受信した音声信号を音声に変換し、変換した音声を出力する。 The speaker 176 converts the audio signal received by the communication unit 74 from the communication unit 56 of the drone 150 into sound, and outputs the converted sound.
　オペレータは、ドローン１５０を操作して、ドローン１５０を部品実装機１０の周囲の適切な位置に移動させる。すると、マイク１５４が部品実装機１０から発生する音を受音する。マイク１５４で受音した音は、音声信号に変換され、通信部５６を介して管理装置１７０の通信部７４に送信される。管理装置１７０のスピーカ１７６は、受信した音声信号を音声に変換して出力する。判定者（又は判定能力を有するオペレータ）は、出力された音声を確認し、正常な音であるか否かを判定する。例えば、部品実装機１０内に設置されているエア機器やモータ等に不具合や異常が生じると、正常時とは異なる音が発生することがある。判定者は、スピーカ１７６からの音声を確認し、部品実装機１０に異常が生じているか否かを判定する。判定結果は、作業者に報告される。なお、制御部７８が自動で異常であるか否かを判定してもよい。例えば、制御部７８は、正常時の部品実装機１０から発生する音を変換した正常時の音声信号を記憶しており、正常時の音声信号と、マイク１５４で受音した音を変換した音声信号との差分から異常を検出してもよい。 The operator operates the drone 150 to move the drone 150 to an appropriate position around the mounter 10. Then, the microphone 154 picks up the sound generated from the mounter 10 . Sound received by the microphone 154 is converted into an audio signal and transmitted to the communication unit 74 of the management device 170 via the communication unit 56 . A speaker 176 of the management device 170 converts the received audio signal into audio and outputs the audio. A judge (or an operator having judgment ability) confirms the output sound and judges whether or not the sound is normal. For example, when a malfunction or abnormality occurs in an air device, a motor, or the like installed in the mounter 10, a sound different from normal sounds may be generated. The judging person confirms the sound from the speaker 176 and judges whether or not there is an abnormality in the mounter 10 . The judgment result is reported to the operator. It should be noted that the control unit 78 may automatically determine whether or not there is an abnormality. For example, the control unit 78 stores a normal sound signal obtained by converting the sound generated by the component mounter 10 during normal operation, and the normal sound signal and the sound obtained by converting the sound received by the microphone 154. Abnormality may be detected from the difference from the signal.
　なお、上記の実施例１及び２では、部品実装機１０に対して検査を実施したが、このような構成に限定されない。回路基板２に対して作業を行う基板作業機であれば同様の検査を実施することができ、例えば、はんだ印刷機や基板検査機等に対して、ドローン５０、１５０を用いて検査を実施してもよい。 In addition, in Examples 1 and 2 above, the component mounter 10 was inspected, but the configuration is not limited to this. A similar inspection can be performed by a board working machine that performs work on the circuit board 2. For example, the drones 50 and 150 can be used to inspect a solder printing machine, a board inspection machine, or the like. may
　また、上記の実施例１及び２では、ドローン５０、１５０を用いて部品実装機１０の検査対象の撮影画像や音声を取得したが、このような構成に限定されない。例えば、設定エリア６０内を移動可能な自律走行車を用いて、部品実装機１０の検査対象の撮影画像や音声を取得してもよい。この場合にも、オペレータが自律走行車を遠隔操作して、所望の撮影画像や音声を適切に取得することができる。また、ドローン５０、１５０や自律走行車等の移動体は、自動運転によって設定エリア６０内を移動可能であってもよい。例えば、移動体は、設定エリア６０内の地図を記憶しており、移動体が予め設定された経路を移動して所望の撮影画像や音声を取得してもよい。 Also, in the first and second embodiments described above, the drones 50 and 150 are used to acquire the captured images and sounds of the inspection target of the component mounter 10, but the configuration is not limited to this. For example, an autonomous vehicle that can move within the setting area 60 may be used to acquire the photographed images and sounds of the inspection target of the mounter 10 . In this case as well, the operator can remotely control the autonomous vehicle to appropriately acquire desired captured images and sounds. In addition, moving bodies such as the drones 50 and 150 and autonomous vehicles may be capable of moving within the set area 60 by automatic operation. For example, the mobile object may store a map of the set area 60, move along a preset route, and acquire desired captured images and sounds.
