(Background to this disclosure)
When some abnormality (error event) occurs in the manufacturing equipment, it is conceivable to collect information related to the error and try to eliminate the error. However, it was difficult to understand what caused the abnormality. In addition, when an abnormality occurs in the manufacturing equipment, it is necessary for the operator to directly operate the manufacturing equipment and investigate the cause of the abnormality. While the worker is conducting the investigation, product manufacturing by the manufacturing equipment is stopped. As a result, the production efficiency of the product is lowered, and it is necessary to assign or dispatch a worker to the factory floor where the manufacturing equipment is arranged, so that the manufacturing cost is also high.

Therefore, in the following embodiment, information from a plurality of monitoring devices for monitoring the status of a plurality of manufacturing devices arranged on the factory floor is collected and stored in the management device. Then, the cause of various events including an abnormality in the manufacturing equipment can be remotely grasped without dispatching a worker to the factory floor.

Hereinafter, embodiments in which the management device and management method according to the present disclosure are specifically disclosed will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanations of already well-known matters and duplicate explanations for substantially the same configuration may be omitted. This is to avoid unnecessary redundancy of the following description and to facilitate the understanding of those skilled in the art. It should be noted that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

FIG. 1 is a conceptual diagram showing a factory floor FL in which a plurality of manufacturing apparatus EQs are arranged. A plurality of manufacturing apparatus EQs, which may be, for example, a chip mounter (mounting machine), are arranged on the factory floor FL (EQ1 to EQ6). A passage PA is provided on the factory floor FL, and a worker WKR, a self-propelled transfer robot (not shown), and the like move on the passage PA. The worker WKR operates the manufacturing apparatus EQ via a means such as a touch panel. The worker WKR performs various operations on the factory floor FL, such as replacement of a tape feeder that supplies a tape containing an electronic chip (hereinafter, simply “chip”). The worker WKR or the transfer robot moves in the factory floor FL to transfer the replacement parts used by the manufacturing apparatus.

In this example, six manufacturing devices EQ1 to EQ6 are arranged on the factory floor FL. The three manufacturing devices EQ1 to EQ3 form the first manufacturing device line, and the three manufacturing devices EQ4 to EQ6 form the second manufacturing device line. For example, a passage PA is provided between the first row of manufacturing equipment and the second row of manufacturing equipment. The arrangement of the plurality of manufacturing apparatus EQs on the factory floor FL is merely an example, and the manufacturing apparatus EQ and the passage PA can be arranged on the factory floor FL in various layouts.

As an example of a monitoring device for monitoring the inside of the factory floor FL, cameras CAM1 to CAM10 are attached to, for example, the ceiling of the factory floor FL. A monitoring device is a device that monitors a target such as a manufacturing device EQ and regularly or constantly acquires monitoring information (sensor information). For example, if the monitoring device is a camera, the image data (still image or moving image) captured by the camera is the monitoring information (sensor information). If the monitoring device is a microphone, the audio data recorded by the microphone is the monitoring information. If the monitoring device is a flow sensor, pressure sensor, thermometer, wattmeter, etc., the flow value, pressure value, temperature value, power value, etc. measured by these devices are the monitoring information. As will be described later, these monitoring information are aggregated and accumulated by the management device 3 (see FIG. 3), and are used when identifying the cause of various events (occurrence of abnormality, etc.) generated in the manufacturing device EQ.

The arrangement of the cameras CAM1 to CAM10 shown in the figure is an example, and the cameras may be arranged on the factory floor FL in another layout. Each of the cameras CAM1 to CAM6 is attached at a position where one manufacturing apparatus EQ is imaged from the front direction or the obliquely upward direction, the camera CAM1 is the manufacturing apparatus EQ1, the camera CAM2 is the manufacturing apparatus EQ2, and so on. , The camera CAM6 images the manufacturing apparatus EQ6, respectively. The cameras CAM1 to CAM6 may be arranged at positions where a user interface (described later) such as a touch panel included in the manufacturing devices EQ1 to EQ6 can be imaged.

The cameras CAM7 to CAM10 are arranged at positions where the passage PA arranged between the manufacturing apparatus EQs and the manufacturing apparatus EQ facing the passage PA can be imaged, respectively. For example, the camera CAM 7 is arranged at a position where the first row of manufacturing devices composed of the manufacturing devices EQ1 to EQ3 can be imaged from the right side. The camera CAM 8 is arranged at a position where the first manufacturing apparatus row can be imaged from the left side. The camera CAM 9 is arranged at a position where a second row of manufacturing devices composed of manufacturing devices EQ4 to EQ6 can be imaged from the right side. The camera CAM 10 is arranged at a position where the second manufacturing apparatus row can be imaged from the left side. For example, by arranging the cameras CAM7 to CAM10 at the above positions, the situation around the manufacturing device EQ, the situation between adjacent manufacturing device EQs, and the behavior of the worker WKR and the transfer robot in the vicinity of the manufacturing device EQ. Etc. can be imaged.

Each of the cameras CAM1 to CAM10, which is an example of the monitoring device, can communicate with other devices via the base station BS1 or the like provided on the factory floor FL. Specific examples of other devices may be various devices provided in the factory floor FL (including the management device 3 when arranged on the same factory floor FL), and may be in a place different from the factory floor FL (for example,). It may be various devices (for example, the management device 3 arranged in the monitoring room MR) provided in the monitoring room MR located at a place away from the factory floor FL. In this example, information communication is performed between the cameras CAM1 to CAM10, which are examples of monitoring devices arranged on the factory floor FL, and the management device 3 arranged in the monitoring room MR by wireless communication using the IP protocol. It is done. However, information communication may be performed between each device by connecting the devices by wire. In order to perform information communication, individual identifiers are assigned to each of the monitoring devices CAM1 to CAM10. The individual identifier may be the ID, MAC address, IP address, etc. of the monitoring device, but an identifier other than these may be assigned to the monitoring device.

FIG. 2 is a conceptual diagram illustrating a manufacturing apparatus EQ arranged on the factory floor FL. The manufacturing device EQ is a device that is installed in a factory and manufactures various products. The manufacturing apparatus EQ may be, for example, a solder printing apparatus, a printing inspection apparatus, a component mounting apparatus, a mounting inspection apparatus, a reflow apparatus, or the like, but may be other than these.

The manufacturing apparatus EQ has a manufacturing apparatus main body 1. The manufacturing apparatus main body 1 includes a control unit 11 and a user interface 12. The control unit 11 is arranged in the manufacturing apparatus main body 1 and is connected to the information management apparatus MGR described later via a communication line (not shown) (see FIG. 3). The user interface 12 is typically a touch panel. The user interface 12 receives the operation input of the manufacturing apparatus EQ by the worker WKR, and outputs (displays, etc.) the information to the worker WKR. However, the user interface 12 is not limited to the touch panel, and may be configured by a single unit or a combination of control buttons, levers, monitors, speakers, and the like.

The device internal camera 21, which is an example of the monitoring device, is arranged at a position where the inside of the manufacturing apparatus main body 1 can be imaged, and images the inside of the manufacturing apparatus main body 1. For example, when the manufacturing device EQ is a component mounting device such as a chip mounter, the vicinity of the tip of the suction nozzle used when mounting the chip on the substrate and the chip supply position where the chip is supplied may be imaged. The image pickup target of the device internal camera 21 is not limited to this, and a portion of the manufacturing device EQ where various errors are likely to occur may be arranged at a position where image pickup is possible.

The worker camera 22, which is an example of the monitoring device, captures the appearance of the worker WKR operating the manufacturing apparatus EQ, facial expressions, and the like. The worker camera 22 may additionally have a face recognition function, an iris recognition function, and the like. The worker WKR operates the manufacturing apparatus EQ via the user interface 12. Therefore, the worker camera 22 may be arranged in the vicinity of the user interface 12. The worker camera 22 may be integrated with a touch panel or the like which is a user interface 12. The worker camera 22 may take an image of a person other than the operator who approaches the manufacturing apparatus EQ.

The microphone 23, which is an example of the monitoring device, acquires the voice of the worker WKR who operates the manufacturing apparatus EQ and the sound generated in the vicinity of the worker WKR. Like the worker camera 22, the microphone 23 may be located near the user interface 12. Further, it may be integrated with the microphone 23, the touch panel which is the user interface 12, and the like. In addition, as a monitoring device, an internal microphone that acquires the sound generated inside the manufacturing apparatus EQ may be arranged inside the manufacturing apparatus EQ. Further, a floor microphone for acquiring the sound inside the factory floor FL may be arranged as a monitoring device on the wall or ceiling of the factory floor FL.

The above-mentioned device internal camera 21, worker camera 22, and microphone 23, which are examples of monitoring devices, may be preliminarily incorporated in the manufacturing device EQ, or may be attached to the manufacturing device EQ later. Individual identifiers may be assigned to the above-mentioned device internal camera 21, the worker camera 22, and the microphone 23, which are examples of the monitoring device. The individual identifier may be the ID of the monitoring device, the MAC address, the IP address, or the like, but an identifier other than these may be assigned. The floor microphone may be attached to the factory floor FL and may be given an identifier similar to the above.

FIG. 3 is a system block diagram showing a configuration example of a monitoring system including a plurality of manufacturing device EQs and a management device 3 according to an embodiment. In the illustrated configuration example, the management device 3 is arranged in the monitoring room MR, and the monitoring room MR is located at a different location from the factory floor FL. However, the management device 3 and the information management device MGR may be arranged on the factory floor FL.

First, an example of a system configuration on the FL side of the factory floor will be described. The same reference numerals will be given to those having the same configuration as each part of FIG. 2, and the description will be simplified or omitted, and different contents will be described. A plurality of manufacturing apparatus EQs are arranged on the factory floor FL (see FIG. 1). The manufacturing apparatus EQ includes a manufacturing apparatus main body 1 (see FIG. 2). The manufacturing apparatus main body 1 includes a control unit 11, a user interface 12, a working unit 13, a flow rate sensor 14, and a pressure sensor 15. The flow rate sensor 14 and the pressure sensor 15 are examples, and the manufacturing apparatus main body 1 may be provided with various sensors other than these. Various monitoring devices 2 are attached to the manufacturing apparatus EQ. However, the monitoring device 2 may be incorporated in the manufacturing apparatus main body 1 from the beginning.

The control unit 11 controls the user interface 12, the work unit 13, the flow rate sensor 14, and the pressure sensor 15. The control unit 11 is configured by using, for example, a CPU (Central Processing Unit) or an FPGA (Field Programmable Gate Array), and performs various processes and controls in cooperation with a memory (not shown). Specifically, the control unit 11 functionally realizes the log collection unit 111 by referring to the program held in the memory and executing the program. The control unit 11 may control various monitoring devices 2.

The log collecting unit 111 collects (or accumulates) event information indicating an event that has occurred in the manufacturing device EQ, and transmits the event information to the information management device MGR via the communication line LI. The transmission of event information from the log collecting unit 111 to the information management device MGR may be performed periodically, for example, every 3 minutes, and the timing at which a predetermined amount of data is accumulated in the log collecting unit 111. May be sent by. The event information includes information indicating the content of the event that has occurred in the manufacturing apparatus EQ and information indicating the time when the event has occurred. For example, when an event (error event) such as "adsorption error" (error that the chip is not adsorbed normally by the adsorption nozzle) occurs when the manufacturing apparatus EQ is a chip mounter, the log collection unit 111 is notified. , The event information including the error ID (event ID) indicating the adsorption error and the time when the adsorption error occurred may be accumulated. The format of the event information is not limited to the above.

The content of the event indicated by the event information is not limited to the error (error event) of the manufacturing apparatus EQ. For example, the content of the event may be "start of operation by the worker" indicating that the worker has started the operation of the manufacturing apparatus EQ via the user interface 12. Further, it may be an event that can be detected by the manufacturing apparatus EQ, such as a change in the production lot of parts consumed by the manufacturing apparatus EQ, replenishment of consumables, opening / closing of a door, attachment / detachment of an accessory unit, and the like. When the content of the event is "operation start by worker", the event information includes the ID information of the manufacturing apparatus EQ (for example, one of the character strings EQ1 to EQ6), the event ID indicating the operation start event, and the event ID. It may include the time when the operator starts the operation of the manufacturing apparatus EQ. The content of the event may be "the setting value for operating the manufacturing device EQ has been changed by the operator". In this case, the event information includes the ID information of the manufacturing device EQ (for example, the character string EQ1). ~ EQ6, etc.), an event ID indicating a set value change event, and a time when the change of the set value is received by the manufacturing apparatus EQ may be included. The content of the event may be "the operator has instructed the start of operation of the manufacturing device EQ". In this case, the event information includes the ID information of the manufacturing device (for example, any of the character strings EQ1 to EQ6). Etc.), an event ID indicating an operation start instruction event, and a time when the work start instruction is received by the manufacturing apparatus EQ.

Since the user interface 12 is the same as that described with reference to FIG. 2, the description thereof will be omitted here.

The work unit 13 is a functional block that performs a manufacturing operation when the manufacturing apparatus EQ manufactures a product. For example, when the manufacturing apparatus EQ is a chip mounter, the working unit 13 checks a mounting head provided with a suction nozzle for mounting the chip on the substrate, a substrate transport unit for transporting the substrate, and a chip sucked by the suction nozzle by image recognition. It includes a component recognition unit for recognizing a component to be mounted, a substrate recognition unit for recognizing a substrate on which a chip is mounted, a component supply unit (feeder) for providing the chip to a suction nozzle, and the like. However, functional blocks other than these may be included in the working unit 13.

The manufacturing apparatus EQ incorporates a large number of sensors for control by the control unit 11 and event detection. The flow rate sensor 14 and the pressure sensor 15 exemplify a part thereof. When the manufacturing apparatus EQ is a chip mounter, the flow rate sensor 14 is a sensor that detects the flow rate of air flowing in the suction nozzle. When the suction nozzle normally sucks the tip, the flow rate of air flowing from the suction nozzle decreases, but when the suction fails, the flow rate of air increases. Therefore, the "adsorption error" can be detected by the flow rate value acquired by the flow rate sensor 14. When the manufacturing apparatus EQ is a chip mounter, the pressure sensor 15 is a load cell that detects a load acting on the suction nozzle. The control unit 11 can detect the load with the load cell and control the height and pressing force of the suction nozzle. These flow rate sensors 14 and pressure sensors 15 can also correspond to monitoring devices.

The monitoring device 2 is a device that acquires various monitoring information such as images and sounds inside and outside the manufacturing apparatus EQ and transmits the various monitoring information to the management apparatus 3. An example of the monitoring device 2 is a device internal camera 21, a worker camera 22, a microphone 23, a thermometer 24, a power meter 25, and the like. These monitoring devices may be attached to the manufacturing apparatus EQ later, and the acquired information (monitoring information) such as images, sounds, temperature values, and power values is transmitted via the base stations BS1 and BS2. , Can be transmitted to the management device 3. When the monitoring device 2 is incorporated in the manufacturing device EQ from the beginning, or when the monitoring device 2 is connected to the control unit 11, various monitoring information acquired by the monitoring device 2 is the above-mentioned event information. Similarly, it may be stored in the log collecting unit 111 and transmitted to the management device 3 via the communication line LI.

Each monitoring device 2 may be given an individual identifier. The individual identifier may typically be the ID of the monitoring device, the MAC address, the IP address (source IP address), or the like, but an identifier other than these may be assigned.

As described with reference to FIG. 2, the device internal camera 21 captures the inside of the manufacturing device main body 1 as monitoring information. More specifically, the device internal camera 21 images a predetermined portion of each device included in the working unit 13. Since the worker camera 22 and the microphone 23 have the same configurations as those described with reference to FIG. 2, the description thereof will be omitted here.

When the thermometer 24 is attached to the outside, it acquires the temperature (atmospheric temperature) outside the manufacturing apparatus EQ. When the thermometer 24 is mounted inside, it acquires the temperature inside the manufacturing apparatus EQ, particularly the temperature of the working unit 13 (for example, a driver for each axis, a motor for each axis, a controller, a heat source such as a heater, etc.). The power meter 25 is arranged at an input end of the manufacturing apparatus EQ or the like, and measures the electric power consumed per unit time of the manufacturing apparatus EQ. When the power meter 25 is arranged inside the manufacturing apparatus EQ, it measures the power consumed per unit time for electric devices such as drivers, controllers, and heaters for each axis. In addition, various sensors such as a hygrometer and an object detection sensor may be arranged inside and outside the manufacturing apparatus EQ to acquire monitoring information.

The communication line LI communicatively connects the manufacturing apparatus EQ and other equipment on the network (for example, another manufacturing apparatus). The communication line LI may connect the equipment in the factory floor FL and the equipment in the monitoring room MR (for example, the information management device MGR described later) in a communicable manner. The communication line LI may be a dedicated line or a shared wired line. The communication line LI may connect the equipment in the factory floor FL and the equipment in the monitoring room MR in a communicable manner via the Internet.

Next, an example of the system configuration on the MR side of the monitoring room in FIG. 3 will be described. In the monitoring room MR, an information management device MGR and a management device 3 according to the embodiment are arranged.

The information management device MGR aggregates and manages various types of information (event information, monitoring information, etc.) transmitted from a plurality of manufacturing device EQs arranged on the factory floor FL. The information management device MGR may transmit a control signal for remotely controlling the manufacturing device EQ to each manufacturing device EQ. The information management device MGR transmits the above-mentioned event information and monitoring information received from the manufacturing device EQ to the management device 3. The information management device MGR may be arranged on the factory floor FL side instead of the monitoring room MR side.

The management device 3 includes a processing unit 31, a communication interface 32, an output unit 33, a first storage unit 34, a second storage unit 35, an input unit 36, an analysis unit 37, an event information storage unit 38, and a setting information storage unit 39. Be prepared.

The processing unit 31 controls the communication interface 32, the output unit 33, the first storage unit 34, the second storage unit 35, the input unit 36, the analysis unit 37, the event information storage unit 38, and the setting information storage unit 39. The processing unit 31 is configured by using, for example, a CPU (Central Processing Unit) or an FPGA (Field Programmable Gate Array), and performs various processes and controls in cooperation with a memory (not shown). Specifically, the processing unit 31 functionally realizes the duplication processing unit 311 and the display processing unit 312 by referring to the program held in the memory and executing the program. Further, the processing unit 31 acquires monitoring information from the communication interface 32 via the base station BS2, and event information and monitoring information from the information management device MGR. The processing unit 31 is an example of a monitoring information acquisition unit.

The communication interface 32 receives monitoring information via the base station BS2. Here, the monitoring device 2 (21 to 25) attached to the manufacturing device EQ arranged on the factory floor FL transmits the monitoring information to the management device 3 by a route different from the communication line LI. That is, the monitoring information transmitted by the monitoring devices 2 (21 to 25) reaches the management device 3 via the base stations BS1 and BS2.

The output unit 33 outputs the monitoring information acquired from the manufacturing apparatus EQ and stored in the first storage unit 34 or the second storage unit 35, which will be described later. The output unit 33 reads the monitoring information for a predetermined period including the occurrence time of the event selected by the input unit 36 from the storage units (first storage unit 34 and the second storage unit 35) and outputs the monitoring information. The output unit 33 is typically a monitor (display) and displays monitoring information. The output unit 33 may be a single monitor or a combination of a plurality of monitors. Further, the output unit 33 may include a speaker or the like that outputs sound. An example of outputting monitoring information by the output unit 33 will be described later with reference to FIG.

The first storage unit 34 stores the monitoring information acquired from the manufacturing device EQ via the base station BS2 or the information management device MGR. Since the monitoring device constantly monitors the internal and external conditions of the manufacturing apparatus EQ, the monitoring information stored in the first storage unit 34 increases with time. On the other hand, since the storage capacity of the first storage unit 34 is a finite value, the first storage unit 34 may store monitoring information for a predetermined period and delete the monitoring information after the predetermined period. ..

The first storage unit 34 may store the monitoring information in a form organized (sorted or grouped) for each monitoring device. For example, a different file or folder may be created for each monitoring device in the first storage unit 34, and monitoring information may be stored in the file or folder. In addition, when the first storage unit 34 is implemented using a database, an identifier (monitoring device ID, IP address, MAC address, etc.) that can uniquely identify the monitoring device is set as a key for information retrieval. Above, the monitoring information may be registered in the database.

The second storage unit 35 stores a copy of the monitoring information necessary for identifying the cause of the event (typically an error event) that has occurred in the manufacturing apparatus EQ. The copy processing of the monitoring information may be performed by the duplication processing unit 311 described later.

The input unit 36 may include a keyboard, a mouse, a touch panel, and the like, and has a function as a human interface with the user, and inputs the user's operation to the management device 3. The input unit 36 accepts the selection of the manufacturing apparatus EQ (see FIG. 5). The input unit 36 accepts the selection of the event recorded in the event information (see FIG. 5). Further, the input unit 36 receives a setting input for setting monitoring information to be output to the output unit 33 according to the content of the event. The setting value of the monitoring information to be output (which monitoring information to output) according to the content of the event may be stored in the setting information storage unit 39 in a format such as a table format (not shown).

The analysis unit 37 will be described later.

The event information storage unit 38 stores the event information received by the processing unit 31. This event information may be stored in the form of an event list (see the event list LST displayed in the display area SEC8 of FIG. 5). The event list stored in the event information storage unit 38 may include information indicating the content (event name) of the event and information indicating the time (date and time) when the event occurred. The processing unit 31 updates the event list. The processing unit 31 updates the event list stored in the event information storage unit 38 based on the event information received from the information management device MGR.

The setting information storage unit 39 stores various setting values. The setting information storage unit 39 stores information indicating a correspondence relationship between the manufacturing apparatus EQ and the monitoring device.

Here, reference is made to FIG. FIG. 4 is a conceptual diagram showing an example of a format of information stored in the setting information storage unit 39 of the management device 3 according to the embodiment and showing the correspondence relationship between the manufacturing device EQ and the monitoring device. Information indicating the correspondence between the manufacturing apparatus EQ and the monitoring device may be stored in the setting information storage unit 39 in a table format such as the illustrated table T.

The table T has "manufacturing device ID", "MDID", "IP address", and "sensor type" as information items (columns of the table). The information item "manufacturing device ID" is ID information that can identify the manufacturing device. The information item "MDID" is ID information that uniquely identifies the monitoring device, and is an example of the above-mentioned identifier. The information item "IP address" is an IP address (source IP address) assigned to the monitoring device, and is an example of the above-mentioned identifier. The information item "sensor type" is information indicating the type of the monitoring device. The camera for the manufacturing apparatus corresponds to the cameras CAM1 to CAM6 shown in FIG. The floor camera corresponds to the cameras CAM7 to CAM10 shown in FIG.

Here, one monitoring device may correspond to a plurality of manufacturing apparatus EQs. For example, the floor camera (CAM7 in FIG. 1) having an MDID of 20001 corresponds to the manufacturing devices EQ1 to EQ3. Therefore, a plurality of records (rows) having an MDID value of 20001 are included in the table T.

Information indicating the correspondence between the manufacturing device EQ and the monitoring device is stored in the setting information storage unit 39 in the format shown in the above table T, so that the manufacturing device selected by the user via the input unit 36. It is possible to identify the monitoring device that corresponds to the EQ. For example, the processing unit 31 has a correspondence relationship with the selected manufacturing device EQ by extracting the “MDID” that uniquely identifies the monitoring device using the manufacturing device ID of the manufacturing device EQ selected by the user as a search key. The monitoring device can be identified.

Contrary to the above, the processing unit 31 uses the "MDID" that uniquely identifies the monitoring device and the IP address information of the monitoring device as a search key to extract the manufacturing device ID from the table T to obtain the monitoring device. It is also possible to identify the corresponding manufacturing apparatus EQ.

The format of the information indicating the correspondence between the manufacturing apparatus EQ and the monitoring device is not limited to the above-mentioned table T.

The management device 3 that has received the monitoring information via the base stations BS1 and BS2 has the table T in the setting information storage unit 39 based on the MDID information or the IP address (source IP address) information included in the monitoring information. Refer to. By this reference, it is possible to identify which of the plurality of manufacturing devices EQ1 to EQ6 the monitoring information is related to. The management device 3 stores the received monitoring information in the first storage unit 34 in a state of being associated with the manufacturing device related to the monitoring information.

See FIG. 3 again. The analysis unit 37 analyzes the monitoring information stored in the first storage unit 34 and the second storage unit 35, and identifies (or estimates) the cause of the event (error or the like) in the manufacturing apparatus EQ. This cause identification (estimation) can be realized by implementing an analysis program in the analysis unit 37 in advance. The analysis program is, for example, the information included in the event information (for example, the event ID) and the monitoring information acquired by the monitoring device at the time corresponding to the occurrence time of the event (for example, a predetermined period including the occurrence time of the event). It may be a program that uses and as an input parameter and outputs a specific or estimated cause of error. As an example, the information indicating the investigation result of the past error cause investigation (including the case where the worker WKR or the user of the management device 3 manually investigates) is the error content (event ID) and the error cause. The events specified as (air leakage, operator WKR operation error, nozzle position setting deviation, etc.) are combined and stored in one of the storage areas. Then, when the event ID is input as an input parameter, the analysis program has a high number of times (or its probability) that the event presumed to be the cause of the error is identified as the cause of the error in the past error cause investigation. The program may be arranged in order and displayed on the output unit 33.

When performing analysis using artificial intelligence, a trained model is implemented in the analysis unit 37. In this trained model, when the information included in the event information is input, each event that can cause an error (air leakage, operator WKR operation error, nozzle position setting deviation, etc.) is regarded as the cause of the error. It may be a trained model that outputs the probability of becoming or the score value of the event. Such a trained model may be formed by using information indicating the investigation results of the past error cause investigation (including the case where the worker WKR or the user of the management device 3 manually investigates). For example, the above-mentioned input parameters (causes have been investigated) are input to a neural network constructed on the management device 3 or another cloud server, and information indicating an event that is the cause of the already identified error is provided as teacher data. To perform machine learning. As a result, the above-mentioned learning model is formed.

(Registration process of event information in the second storage unit 35)
When an event expected in advance occurs in the manufacturing apparatus EQ, the duplication processing unit 311 performs a process of duplicating a part of the monitoring information related to the event from the first storage unit 34 to the second storage unit 35. This process is referred to as "registration of event information". For example, when the event for which the cause of occurrence is desired to be specified is "adsorption error", the duplication processing unit 311 copies the monitoring information before and after the occurrence of the event from the first storage unit 34 to the second storage unit 35.

The monitoring information before and after the occurrence of the above-mentioned event, which is copied from the first storage unit 34 to the second storage unit 35, is, for example, a monitoring device (adsorption error) during M seconds before and after the time when the “adsorption error” occurs. The monitoring information acquired by the manufacturing apparatus EQ in which the above is generated is copied from the first storage unit 34 to the second storage unit 35. M may have a different value for each event, and may be stored in the setting information storage unit 39 as setting information.

More specifically, the duplication processing unit 311 stores the monitoring information of the manufacturing device EQ in which the event has occurred and the monitoring device corresponding to the manufacturing device EQ in the setting information storage unit 39 in the table T. Identify while referring. Alternatively, the duplication processing unit 311 extracts an event for which registration of event information in the second storage unit 35 has not yet been completed from the event list stored in the event information storage unit 38, and is related to the extracted event. Identify the monitoring device and monitoring information to be used.

From the monitoring information of the specified monitoring device stored in the first storage unit 34, the duplication processing unit 311 receives only a predetermined time before and after the event occurrence time (for example, M seconds before and after the occurrence time). Copy to the second storage unit 35 (registration of event information in the second storage unit 35). At the time of the above copying, the duplication processing unit 311 includes the monitoring information to be registered in the second storage unit 35, the manufacturing device ID, the event (list number of the event list stored in the event information storage unit 38, etc.). , And the monitoring information to be registered is stored in the second storage unit 35 in the state of associating the occurrence time of the event.

The timing of registering the event information in the second storage unit 35 does not have to be the same as the occurrence of the event to be registered as long as the monitoring information is not deleted from the first storage unit 34. For example, in batch processing at night, event information may be registered in the second storage unit 35 during a time period when the system load in the monitoring system is small.
