JP7573714B2 - Management device, implementation system, and error handling method - Google Patents

Description

The present disclosure, which is the invention disclosed in this specification, relates to a management device, an implementation-related device, and an implementation system.

A conventional management device has been proposed that, for example, stores image processing errors in association with corresponding countermeasures for those errors in advance, and when an image processing error occurs, selects the corresponding countermeasure and displays a screen requesting permission to use that countermeasure (see, for example, Patent Document 1). This device has, for example, a low-speed movement mode for the suction nozzle as a countermeasure for misalignment of the component suction position, and can reduce the workload of the worker by reflecting the countermeasure in the operation of the mounting device, such as capturing an image in the low-speed movement mode after obtaining the worker's permission.

JP 2015-135886 A

However, while the device of Patent Document 1 mentioned above is able to reduce the workload of workers by reflecting the error handling method in the operation of the mounting device, there are also errors for which the handling method cannot be reflected. Such errors include, for example, an error that stops the device after a certain number of counts. When such an error occurs, it may not necessarily require a visual check by the worker, but the worker is required to visually check the mounting device directly. It is desirable to further reduce the amount of work that workers must deal with in a mounting system.

The present disclosure has been made in consideration of these problems, and has as its main objective the provision of a management device, a mounting-related device, and a mounting system that can further reduce the tasks that workers must perform in mounting-related devices.

The management device, implementation-related device, and implementation system disclosed in this specification employ the following means to achieve the above-mentioned primary objective.

The management device disclosed in this specification is
A management device is used in a mounting system including one or more mounting-related devices each having a mounting-related processing unit that performs a mounting-related process related to a mounting process of mounting components on a board, the management device exchanging information with the mounting-related devices via a network,
A display unit that displays information to a user;
an input unit for inputting instructions from a user;
an acquisition unit that acquires information from the mounting-related device via the network;
an output unit that outputs information to the mounting-related device via the network; and a management control unit that, when the acquisition unit acquires from the mounting-related device device stop information indicating that the device has stopped based on an error in the mounting-related processing unit, which stops the device after a predetermined number of counts, causes the display unit to display the device stop information, and, when an instruction to resume execution is input from the input unit, causes the output unit to output a resume command to resume the mounting-related processing and a command to reset the error count number to the mounting-related device that is currently stopped.
It is equipped with the following:

In this management device, when device stop information is acquired from the mounting-related device that the device has stopped based on an error in the mounting-related processing unit, which stops the device after counting a predetermined number of times, the display unit displays that information. When the user inputs an instruction to resume execution from the input unit after checking the contents of the display unit, the management device outputs a restart command to resume the mounting-related processing and a reset command for the error count number to the mounting-related device that is stopped. In this way, in this management device, the mounting-related processing of the mounting-related device is resumed at the discretion of the user of the management device, so that the work that the worker must handle at the mounting-related device can be further reduced. Here, the mounting-related processing includes one or more of the mounting processing for mounting components on a board, the printing processing for printing a viscous fluid on the board, the transport processing for transporting the board, and the inspection processing for inspecting the condition of the components and/or the board. In addition, the "predetermined number of times" may be empirically determined, for example, as a number of times that can be determined to be not accidental (e.g., three or five times), or a number of times that can be determined to cause unnecessary delays until production is completed.

In this embodiment, devices related to reflow are omitted for the sake of convenience.

A worker M is assigned to each device on the mounting line 11. The worker M performs various tasks on the mounting line 11 while wearing an ID card 17 that stores the worker's information. On the mounting line 11, the information on the ID card 17 is read by a reading device (not shown), making it possible to identify the worker M working on each mounting line 11. In addition, the worker M carries a mobile terminal 18 when working on the mounting line 11. The mobile terminal 18 can exchange information with the mounting device 15 and the management PC 50 via the network 12, and displays information related to the mounting line 11. Note that on the mounting line 11, the worker M may be identified by entering his or her card when entering the room.

The printing device 13 is a device that executes a printing process to print solder on a substrate. The printing device 13 includes a printing control unit 21, a transport unit 22, a printing unit 23, and a communication unit 24.

The transport unit 22 is a unit that transports and fixes the substrate S. The printing unit 23 is a unit that prints a viscous fluid such as a conductive paste or adhesive on the substrate S. The printing unit 23 may apply (print) solder to the substrate below through the pattern holes by pushing the solder into pattern holes formed in a screen mask using a squeegee. The communication unit 24 receives and transmits information to other devices via the network 12.

The print inspection device 14 is a device that inspects the state of the printed viscous fluid. The print inspection device 14 is equipped with an inspection control unit, a transport unit, an inspection unit, and a communication unit. The inspection unit of the print inspection device 14 is a unit that inspects whether the print state is proper or not based on an image captured by an imaging unit of the substrate S on which the viscous fluid is printed. This print inspection device 14 has a similar configuration to the mounting inspection device 16 described later, and a detailed description thereof will be omitted here.

The mounting device 15 is a device that executes a mounting process to mount a component P on a board S. As shown in FIGS. 1 and 2, the mounting device 15 includes a mounting control unit 30, a transport unit 35, a supply unit 36, a component imaging unit 37, a mounting unit 38, a mark imaging unit 42, and a communication unit 43. The mounting control unit 30 is configured as a microprocessor centered on a CPU 31, and includes a memory unit 32 that stores various data and a counter 33. The mounting control unit 30 exchanges information with the transport unit 35, the supply unit 36, the component imaging unit 37, the collection unit 40, the mark imaging unit 42, and the communication unit 43, and controls them. The counter 33 counts the number of occurrences of an error (also called a recovery-up error) that stops the processing operation of the mounting device 15 when the occurrence of the error is counted a predetermined number of times. In the mounting line 11, the recovery-up errors include, for example, an error of failure to pick up the component P, an image processing error when obtaining the shape and state of the picked component P from the captured image, a transport error of the board S by the transport unit 35, a fixing error of the board S, a supply error of the component P by the supply unit 36, a printing processing error by the printing unit 23, an inspection error by the inspection unit 27, and the like. The predetermined number of times is empirically determined as, for example, a number of times that can be determined to be not an accidental occurrence of the error (for example, three times or five times), or a number of times that can be determined to cause an unnecessary delay until the production is completed. The counter 33 is provided in the mounting control unit 30 for each of the multiple existing recovery-up errors. The transport unit 35 is a unit that transports and fixes the board S. The supply unit 36 is a unit that supplies the component P to the mounting unit 38. The supply unit 36 includes, for example, a feeder on which a tape holding the component P is attached, a tray on which the component P is arranged, and the like. The component imaging unit 37 is a unit that captures an image of one or more components P captured by the collection unit 40, with the imaging range being the upper side. The mounting unit 38 is a mounting unit that captures components P from the supply unit 36 and places them on the board S fixed to the transport unit 35. The mounting unit 38 includes a head moving unit 39, a collection unit 40, a suction nozzle 41, and a mark imaging unit 42. The head moving unit 39 includes a slider that moves in the XY directions guided by a guide rail, and a motor that drives the slider. The collection unit 40 is a mounting head that is removably attached to the slider, and moves in the XY directions by the head moving unit 39. One or more suction nozzles 41 are removably attached to the underside of the collection unit 40. The suction nozzle 41 is for collecting components P by utilizing negative pressure. The collection of components P may be performed by a mechanical chuck that mechanically holds the components P, in addition to the suction nozzle 41. The mark imaging unit 42 is a unit whose imaging range is below and which images marks formed on, for example, the substrate S. The mark imaging unit 42 is disposed on the underside of the collection unit 40 and moves in the XY directions as the collection unit 40 moves. This mark imaging unit 42 can also image the component collection position of the supply unit 36. The communication unit 43 receives and transmits information to other devices via the network 12.

The mounting inspection device 16 is a device that inspects the mounting state of the component P that has been mounted. The mounting inspection device 16 includes an inspection control unit 25, a transport unit 26, an inspection unit 27, and a communication unit 28. The inspection control unit 25 is configured as a microprocessor centered on a CPU, and includes a memory unit that stores various data. The inspection control unit 25 exchanges information with the transport unit 26, the inspection unit 27, and the communication unit 28, and controls them. The transport unit 26 is a unit that transports and fixes the board S. The inspection unit 27 is a unit that inspects whether the shape and placement position of the component are appropriate based on an image captured by a camera of the board S on which the component P is placed. The communication unit 28 receives and transmits information to other devices via the network 12.

The reflow device, not shown, is a device that performs the reflow process on the board S. The reflow device heats the board S on which the components P are placed to melt the solder, and then cools it to electrically connect and fix each component P to the board S. The reflow inspection device is a device that inspects the board S after reflow. The reflow inspection device detects the conductivity of the reflowed board and inspects whether it is suitable for use as a final product. The board transport device transports boards from an upstream device to a downstream device on the production line, and is equipped with a transport conveyor.

The management PC 50 is configured as a management device operated by a manager higher than the worker M, and is a computer that manages information related to mounting. The management PC 50 includes a management control unit 51, a communication unit 56, a display unit 57, an input unit 58, and the like. The management control unit 51 is configured as a microprocessor centered on the CPU 52, and includes a memory unit 53 that stores various data. The management control unit 51 exchanges information with the communication unit 56, the display unit 57, and the input unit 58, and controls them. As shown in FIG. 3, the memory unit 53 stores production line information 54, worker correspondence information 55, mounting condition information (not shown), and the like. The production line information 54 is a database in which the type and identifier of the device included in the production line, the production status, information on the worker, and the like are associated with each mounting line 11. The worker correspondence information 55 is a database in which the worker ID, the worker name, the number of the mobile terminal they own, and the information on the device they are responsible for are associated with each work area. When an abnormality occurs in the device, the management PC 50 can search for the mobile terminal 18 of the worker M in charge using the production line information 54 and the worker correspondence information 55. The mounting condition information includes job information such as which component is to be placed at which position on which mounting device of which mounting line 11. The communication unit 56 outputs and acquires information from other devices via the network 12. The display unit 57 is a liquid crystal display that displays a screen. The input unit 58 is a device for inputting instructions from the worker, such as a mouse or keyboard. The management PC 50 exchanges information with each device of the mounting line 11 connected to the network 12. For example, the management PC 50 acquires the consumption state of solder from the printing device 13, the consumption state of components contained in the feeder from the mounting device 15, and inspection results from each inspection device via the communication unit 56. The management PC 50 also receives error information from each device.

Next, as a specific example of the mounting-related process, the mounting process executed by the mounting device 15 will be described. FIG. 4 is a flowchart showing an example of a mounting process routine executed by the CPU 31 of the mounting device 15. This routine is stored in the storage unit 32 and is executed based on the mounting start input of the worker M. Here, as a specific example of the recovery-up error of the mounting device 15, a component P picking error, a picking position shift during the mounting process, and an image processing error of the captured image of the component P during shape confirmation will be mainly described. When this routine is started, the CPU 31 first acquires mounting condition information from the management PC 50 (S100), and causes the transport unit 35 to transport and fix the board S (S110). Next, the CPU 31 sets the components P to be placed on the board S based on the arrangement order of the mounting condition information (S120). Next, the CPU 31 determines whether there is a counter 33 in which the number of occurrences of recovery-up errors has reached a predetermined number, such as the set component P (S130). If the number of errors that have occurred has not reached the predetermined number, the CPU 31 causes the mounting unit 38 to perform a process of picking up the component P (S140). At this time, the CPU 31 may perform a process of attaching the suction nozzle 41 corresponding to the component P to the picking unit 40 before picking up the component P.

Next, the CPU 31 judges whether an error has occurred during the collection process of the part P (S150). Examples of errors during the collection process include an adsorption error of the part P and a drop of the part P. When no error has occurred during the collection of the part P, the CPU 31 causes the head moving unit 39 to carry out the movement process of the part P and causes the part imaging unit 37 to carry out the imaging process of the part P (S160). At this time, the CPU 31 moves the collection unit 40 so that it passes above the part imaging unit 37 after collecting the part P. The CPU 31 also performs a matching process using a predetermined reference image and the captured image to judge whether the collected part P has deformation beyond the allowable range or a collection position deviation. Next, the CPU 31 judges whether an error has occurred during this image processing (S170). Examples of image processing errors include an identification error in which the part P cannot be identified due to the brightness of the captured image, and a matching error in which the part shape of the reference image does not match the part shape in the captured image. When no error occurs in the image processing, the CPU 31 uses the captured image to determine the amount of collection deviation, and places the component P at a position where the amount of deviation has been corrected (S180). Note that at this time, the CPU 31 may discard the component P whose shape is outside the allowable range, or whose collection position has been deviated beyond the allowable range such that accurate placement processing cannot be performed.

Then, the CPU 31 judges whether the mounting process of the current board S is completed (S190), and if not, executes the process from S120 onwards. That is, the CPU 31 sets the next component P to be picked up, picks up the component P, takes an image of it, corrects the picking deviation amount, and places it on the board S. During this process, if an error occurs in S150 or S170, the corresponding counter 33 is incremented by 1 (S200), a placeable component is placed on the board S (S210), and the process from S120 onwards is executed. The CPU 31 may perform a discard process for the component P that cannot be placed. In this mounting system 10, even after the number of errors has reached a predetermined number, the process other than the corresponding process is set to continue. When the process from S120 onwards is repeatedly executed, if there is a counter 33 where the number of recovery-up errors has reached a predetermined number in S130, the CPU 31 stops the mounting process of the corresponding device and transmits device stop information including information to that effect to the management PC 50 (S220).

Next, the CPU 31 judges whether or not an image transmission command of the unit that caused the device to stop has been received from the management PC 50 (S230), and when an image transmission command has been received, transmits an image of the unit that caused the device to stop (S240). When the device has stopped due to a collection error of the component P, the CPU 31 moves the collection unit 40 so that the mark image capture unit 42 is located above the collection position where the error occurred, causes the mark image capture unit 42 to capture the collection position of the component P, and transmits the captured image to the management PC 50. When the device has stopped due to an image processing error, the captured image where the image processing error occurred is transmitted to the management PC 50. After S240, or when the image transmission command has not been received in S230, the CPU 31 judges whether or not a restart command for the mounting-related process and a reset command for the counter 33 have been received (S250). The restart command and reset command may be obtained from the management PC 50 via the network 12, or may be obtained by the operator M inputting them from the operation panel of the mounting device 15. The restart command from the management PC 50 is input by the administrator through the input unit 58 after remotely checking an image of the cause of the device stop, as will be described later in detail. The restart command from the operation panel is input from the operation panel after the worker M has performed work to eliminate the cause of the error with the mounting device 15. When neither a restart command nor a reset command has been received, the CPU 31 waits in the device stopped state, and when a restart command or a reset command has been received, the CPU 31 resets the counter 33 (S260), releases the device stopped state, and executes the process from S140 onwards. The counter 33 is reset by resetting all counters 33 or resetting the relevant counters individually, depending on the content of the reset command. Since the mounting device 15 may need to deal with all errors, the method of resetting the counter 33 when resuming processing can be selected.

On the other hand, when the mounting process for the current board is completed in S190, the CPU 31 ejects the completed board S by the transport unit 35 (S270) and determines whether production is complete (S280). If production is not complete, the CPU 31 executes the process from S110 onwards, but when production is complete, the routine ends. In this way, the mounting device 15 performs mounting processing and manufactures the board S while stopping processing in response to the occurrence of a recovery-up error.

Next, the operation of the management PC 50 executed during the production process of the mounting system 10, particularly the process of notifying the administrator of information on the mounting line 11, will be described. FIG. 5 is a flowchart showing an example of a system management process routine executed by the management control unit 51 of the management PC 50. This routine is stored in the storage unit 53 of the management PC 50 and is executed during the production process of the mounting system 10. When this routine is started, first, the CPU 52 of the management control unit 51 acquires information from the mounting line 11 (S300). Examples of the information on the mounting line 11 include information on the completion of production, instructions for a changeover to install the next feeder, instructions to switch the mounting job and start production, instructions to replenish viscous fluid or components P, errors such as equipment failure, and information on equipment stop due to a recovery-up error. Next, the CPU 52 determines whether there is new information to be displayed in the acquired information (S310). When there is new information to be displayed, the CPU 52 displays the acquired information on the display unit 57 (S320).

Figure 6 is an explanatory diagram showing an example of a production status display screen 60 displayed on the display unit 57. The production status display screen 60 has a cursor 61, a status display field 62, a selection frame 63, and a selection key 64. The cursor 61 is operated when selecting information. The status display field 62 is a field that displays the device name, the time when the work occurred, and the work content on each mounting line 11. The selection frame 63 is a field for selecting the device on which the work is occurring, and is moved by the cursor 61. The selection key 64 is a key for confirming the content selected by the selection frame 63. On the production status display screen 60, new information updated at a predetermined timing is inserted and displayed at the top of the status display field 62. The manager operates the selection frame 63 and the selection key 64 to select the content to be confirmed.

Next, the CPU 52 determines whether or not there is an instruction to select device stop information (S330). Device stop information is information that a device has stopped due to a recovery error, and includes device stop due to a component P picking error and device stop due to an image processing error. When there is an instruction to select device stop information, the CPU 52 sends a command to the corresponding device to send an image related to the cause of the stop (S340), and displays a display screen according to the selection (S350). For example, when the stop of the mounting device 15 due to a picking error is selected on the production status display screen 60, the CPU 52 displays the picking position display screen 70 on the display unit 57. Alternatively, when the stop of the mounting device 15 due to an image processing error is selected, the CPU 52 displays the processing image display screen 80 on the display unit 57.

7 is an explanatory diagram showing an example of a pick-up position display screen 70 displayed on the display unit 57. The pick-up position display screen 70 is a screen for confirming whether or not work by the worker M is required for the pick-up error of the component P. The pick-up position display screen 70 has a cursor 61, an image display field 72, an information display field 73, a contact key 74, an individual reset key 75, a full reset key 76, and a restart key 77. The image display field 72 is a field for displaying an image of the pick-up position of the component P in the supply unit 36. The CPU 52 acquires an image of the pick-up position of the component P transmitted from the mounting device 15 and displays it in the image display field 72. In the image display field 72, the XY coordinate axis passing through the center of the planned pick-up position, the circle of the suction nozzle at the planned pick-up position, and the reference image are displayed superimposed on the captured image (see the thin line in the figure). The administrator can check these positional relationships in the image display field 72. The information display field 73 is a field for displaying information related to part pick-up. In the information display field 73, a correction value for correcting the pickup deviation of the suction nozzle 41, a correction value for correcting the deviation of the supply unit 36, position information of the height of the component P and the pickup height, the nozzle movement speed during component pickup, etc. are displayed. In the information display field 73, each value can be changed based on an input from the input unit 58. When the value is changed in the information display field 73, the change is reflected in the image displayed in the image display field 72. When the contact key 74 is pressed, the content of the error is output to the mobile terminal 18 of the worker M in charge of the corresponding device. The manager checks the image display field 72 and presses the contact key 74 when he/she determines that the work of the worker M is necessary. When the individual reset key 75 is pressed, a reset command is output to reset only the counter 33 corresponding to the supply unit 36 currently being checked. When the all reset key 76 is pressed, a reset command is output to reset all the counters 33 of the mounting device 15. When the Resume key 77 is pressed, it outputs a command to release the device from the stopped state due to a recovery error.

FIG. 8 is an explanatory diagram showing an example of a processing image display screen 80 displayed on the display unit 57. The processing image display screen 80 is a screen for confirming whether or not work by the worker M is required for the image processing error of the part P collected by the collection unit 40. The processing image display screen 80 is arranged with a cursor 61, an image display field 82, a reference image editing field 83, a contact key 74, an individual reset key 75, an all reset key 76, and a restart key 77. The image display field 82 is a field for displaying the captured image that has become an image processing error. In the image display field 82, the reference image of the part P is displayed superimposed on the captured image (see the thin line in the figure). The manager can confirm the relationship between the shape of the captured part P and the shape of the reference image in the image display field 72. The reference image editing field 83 is a field for editing the reference image. The part P may have slight differences in shape, such as rounded or sharp corners, depending on the supply company. In the reference image editing field 83, the administrator can edit and change such minute differences in the reference image. The reference image edited in the reference image editing field 83 is reflected in the image display field 82. Note that the contact key 74, individual reset key 75, all reset key 76, and resume key 77 on the processed image display screen 80 are the same as those on the collection position display screen 70, so their explanation will be omitted. In this way, the management PC 50 that manages the mounting line 11 is configured to be able to check the contents of the recovery error and the status of the device, and to edit values, shapes, etc., on the collection position display screen 70 and the processed image display screen 80.

Now, after displaying the display screen in S350, the CPU 52 determines whether or not there is an instruction to restart processing based on whether the restart key 77 is pressed (S360). When there is no instruction to restart processing, the CPU 52 determines whether or not there is an instruction to contact the worker M based on whether the contact key 74 is pressed (S370). When there is an instruction to contact the worker M, the CPU 52 uses the worker correspondence information 55 to search for the worker M in charge of the corresponding device (S380) and outputs information to the mobile terminal 18 of the corresponding worker M (S390). The worker M checks the information received by the mobile terminal 18 and performs work on the corresponding device. On the other hand, when there is an instruction to restart processing in S360, the CPU 52 determines whether or not an instruction to reset all counters is given based on whether the all reset key 76 or the individual reset key 75 is pressed (S400). When an instruction to reset all counters is given, the CPU 52 outputs a command to restart the process and a command to reset all counters 33 to the relevant device (S410). On the other hand, when an instruction to reset all counters is not given, the CPU 52 outputs a command to restart the process and a command to reset the corresponding individual counters 33 to the relevant device (S420). After S410 and S420, or when there is no information to be displayed in S310, when there is no instruction to select device stop information in S330, or when there is no instruction to contact an operator in S370, the CPU 52 repeatedly executes the process from S300 onwards. This management PC 50 can check the contents of the recovery up error in each device of each mounting line 11 and the status of the device, and can edit to change values and shapes, etc., so that it is possible to instruct the mounting-related device to resume the mounting-related process without the operator M having to perform a confirmation operation.

The correspondence between the components of this embodiment and the components of the present invention will now be clarified. In this embodiment, the transport unit 22, printing unit 23, transport unit 26, inspection unit 27, transport unit 35, supply unit 36, mounting unit 38, etc. correspond to the mounting-related processing unit, the communication unit 43 corresponds to the acquisition unit and output unit, the communication unit 24, communication unit 28, communication unit 43, etc. correspond to the receiving unit and sending unit, the print control unit 21, inspection control unit 25, mounting control unit 30, etc. correspond to the processing control unit. In addition, the printing device 13, print inspection device 14, mounting device 15, mounting inspection device 16, reflow device, reflow inspection device, and board transport device correspond to mounting-related devices, and the management PC 50 corresponds to the management device.

In the above-described management PC 50, when the device stop information is acquired from the mounting device 15 (mounting-related device) indicating that the device has stopped based on a recovery-up error that stops the device when the occurrence of an error is counted a predetermined number of times, the display unit 57 displays the information. When the administrator (user) inputs an instruction to resume execution from the input unit 58 after checking the contents displayed on the display unit 57, the management PC 50 outputs a restart command to resume the mounting-related process and a reset command for the error count number to the stopped mounting-related device. In this way, in the management PC 50, the mounting-related process of the mounting-related device is resumed at the discretion of the administrator, so that the work that the worker M must handle at the mounting-related device can be further reduced. In addition, after acquiring the device stop information from the mounting device 15, the management PC 50 outputs a command to send the image that causes the device to stop to the mounting device 15. When the management control unit 51 acquires an image from the mounting device 15, the management control unit 51 displays the image on the display unit 57. In this management PC 50, the administrator can check the image that caused the device to stop, and determine whether or not work is required by the worker M in charge of the mounting device 15. Therefore, this device can more reliably reduce the work of the worker M.

The mounting device 15 also includes a supply unit 36 that supplies components P, a collection unit 40 that collects components P, a component imaging unit 37 that images components P, and a transport unit 35 that transports the board S. The management control unit 51 acquires collection errors from the collection unit 40, image processing errors from the component imaging unit 37, transport errors from the transport unit 35, and the like. The management PC 50 can reduce the work of the worker M for one or more of these errors. Furthermore, the management PC 50 also outputs information to the mobile terminal 18 of the worker M working on the mounting device 15, and when the management control unit 51 inputs work instructions for the mounting device 15 that is stopped from the input unit 58, the management control unit 51 outputs the work instructions to the mobile terminal 18 of the worker M in charge of the stopped mounting device 15. The management PC 50 can more reliably have the worker M perform the work that the worker M must handle on the mounting device 15.

In addition, after the error count of the unit that stops the device when counted a predetermined number of times reaches a predetermined number, the mounting device 15 stops the mounting process of the mounting unit 38 and transmits device stop information to the management PC 50 to the effect that the device has stopped. After that, when the mounting device 15 receives a resume command to resume processing and a command to reset the error count from the management PC 50, it resets the error count of the corresponding mounting device 15 and resumes the mounting process that was stopped by the mounting unit 38. In this way, in this mounting device 15, mounting-related processing is resumed in response to a command from the management PC 50, so the work that the worker M must handle at the mounting device 15 can be further reduced.

Furthermore, the mounting device 15 includes a mark imaging unit 42 capable of capturing an image of the supply unit 36, and when the communication unit 43 receives a command to transmit an image of the unit causing the device to stop from the management PC 50 after transmitting the device stop information from the communication unit 43, the mounting control unit 30 causes the mark imaging unit 42 to capture an image of the unit and transmits the captured image to the management PC 50. In this mounting device 15, the administrator of the management PC 50 can check the image of the unit that caused the device to stop, and determine whether or not work is required by the worker M in charge of the mounting device 15, so that the work of the worker M can be more reliably reduced. Furthermore, the mounting control unit 30 of the mounting device 15 stops the device based on one or more of a collection error of the collection unit 40, an image processing error of the component imaging unit 37, and a transport error of the transport unit 35, and transmits device stop information to the management PC 50. In this mounting device 15, the work of the worker M can be reduced by one or more of these errors.

It goes without saying that the management device and implementation-related device disclosed in this specification are in no way limited to the above-mentioned embodiments, and may be implemented in various forms as long as they fall within the technical scope of the present invention.

For example, in the above-described embodiment, the CPU 52 transmits an image of the cause of the device stop, but this is not limited to this, and this process may be omitted. For example, the image display field 72 may be omitted on the collection position display screen 70, and the image display field 82 may be omitted on the processed image display screen 80. In this case, an error code or the like may be displayed instead of the captured image. Even in this case, the mounting-related process is resumed in the mounting-related device by a command from the management PC 50, so that the work that the operator M must handle at the mounting device 15 can be further reduced.

In the above embodiment, the collection position display screen 70 has an information display field 73, but this may be omitted. Also, in the information display field 73, each numerical value is changeable, but this may be omitted. Furthermore, in the image display field 72, changes to the information display field 73 are reflected, but this may be omitted. Also, in the processed image display screen 80, the reference image editing field 83 is included, but this may be omitted. Also, in the reference image editing field 83, the reference image can be edited, but this may be omitted. Furthermore, in the image display field 82, changes to the reference image editing field 83 are reflected, but this may be omitted.

In the above embodiment, the device stop due to an error in the mounting device 15 has been described, but the same applies to the printing device 13, the print inspection device 14, the mounting inspection device 16, the reflow device, the reflow inspection device, etc. Note that the mounting line 11 may not include one or more of the above devices.

In the above embodiment, the mounting system 10 is described as having a mounting device 15 and a management PC 50, but it may be configured as only the mounting device 15 or only the management PC 50.

Here, in the management device of the present disclosure, the output unit may output a command to send an image of the cause of the device stoppage to the mounting-related device after acquiring the device stoppage information from the acquisition unit, and the management control unit may cause the display unit to display the image when the acquisition unit acquires the image. In this management device, a user can check an image of the mounting-related processing unit or the like that caused the device stoppage, and thus determine whether or not work is required by the worker in charge of the mounting-related device, thereby more reliably reducing the workload of the worker.

In this management device, the mounting-related device includes the mounting-related processing unit having at least one of a supply unit that supplies components, a collection unit that collects the components, an imaging unit that images the components, a transport unit that transports a board, a printing unit that prints a viscous fluid on the board, and an inspection unit that inspects the state of the components and/or the board, and the acquisition unit may acquire the device stop information based on one or more of a collection error in the collection unit, an image processing error in the imaging unit, a transport error in the transport unit, a print processing error in the printing unit, and an inspection error in the inspection unit. In this management device, the work of an operator for one or more of these errors can be reduced. Note that errors that cause the device to stop when counted a predetermined number of times may include a collection error in the collection unit and an image processing error in the imaging unit.

In this management device, the output unit may also output information to a terminal of a worker working on the mounting-related device, and when the management control unit inputs a work instruction for the mounting-related device while the device is stopped from the input unit, the management control unit may output the work instruction from the output unit to a terminal of a worker in charge of the stopped mounting-related device. This management device can more reliably have a worker perform work that the worker must handle on the mounting-related device.

When the mounting-related device subsequently receives a resume command to resume the mounting-related processing and a command to reset the error count from the management device, it resets the error count and causes the mounting-related processing unit to resume the stopped mounting-related processing. In this way, in this mounting-related device, mounting-related processing is resumed in response to a command from the management device, so the amount of work that the operator must do at the mounting-related device can be further reduced.

The mounting-related device may include an imaging unit capable of capturing an image of the mounting-related processing unit, and the processing control unit may cause the imaging unit to capture an image of the mounting-related processing unit and transmit the captured image to the management device when the receiving unit receives a command to transmit an image of the cause of the device stop from the management device after the device stop information is transmitted from the transmitting unit. In this mounting-related device, the user of the management device can check images of the mounting-related processing unit that caused the device stop, and the user can determine whether or not work is required by the worker in charge of the mounting-related device, thereby more reliably reducing the worker's work.
