[0019] In the existing remote control system, when multiple errors occur in multiple working devices at the same time, one operator must quickly and continuously eliminate the multiple errors. Therefore, not only the operator's workload becomes too heavy, but also the waiting time for error elimination increases cumulatively, and the overall productivity of the work line may decrease.

[0020] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Figure 1 A remote operation system 1 in one embodiment of the present disclosure is shown. The remote operation system 1 has a plurality of working devices 2, a server 3, and a plurality of remote monitoring units 4. In the remote operation system 1, the server 3 relays information on errors that occur in the plurality of working devices 2, and transmits it to any of the plurality of remote monitoring units 4. Furthermore, the remote monitoring unit 4 that has received the error information can remotely perform an error elimination operation for eliminating the error. In the present embodiment, the working devices 2 are respectively mounted on a substrate KB as an operating object (e.g., a substrate KB assembly component BH) (see Figure 2 ) component installation device. A plurality of working devices 2 are arranged in series to form a working line 2L.

[0021] exist Figure 2 In the figure, each operation device 2 has a base 11, a transport conveyor 12, a parts feeder 13, a head moving mechanism 14, an assembly head 15, a substrate camera 16, and a component camera 17. The transport conveyor 12 is extended on the base 11 along the left and right direction (X-axis direction) of the base 11, receives the substrate KB sent from the upstream side and positions it at a given operation position. Then, after the component assembly operation described later is performed on the substrate KB, the substrate KB is transported to the downstream side and discharged.

[0022] exist Figure 2 In the embodiment, the parts feeder 13 is a belt feeder, which is connected to the parts feeder by a built-in sprocket 13S (see also Figure 3 ), pulls out the carrier tape CT wound on the reel RL and transports it in the front-rear direction (Y-axis direction) of the base 11, and supplies the component BH to the component supply position 13K set at the end of the transport conveyor 12. The head moving mechanism 14 is composed of, for example, an XY stage mechanism, and moves the assembly head 15 in a horizontal plane. The assembly head 15 has a plurality of nozzles 15N extending downward in the up-down direction (Z-axis direction).

[0023] The assembly head 15 can raise and lower each nozzle 15N in the Z-axis direction. In addition, the assembly head 15 can generate a vacuum suction force at the lower end of each nozzle 15N. After the assembly head 15 positions the nozzle 15N above the component supply position 13K of the part feeder 13, the nozzle 15N is lowered and a vacuum suction force is generated at the lower end of the nozzle 15N to suction the component BH, and the component BH is picked up ( Figure 3 ).

[0024] exist Figure 2 as well as Figure 3 In the figure, the substrate camera 16 is mounted on the assembly head 15 with the imaging optical axis facing downward. The substrate camera 16 is integrated with the assembly head 15 and moves inwardly in the horizontal plane, and photographs the substrate KB positioned at the working position by the transport conveyor 12 from above. In addition, when an error occurs in the working device 2, the substrate camera 16 photographs the part where the error occurs (the error occurrence part) from above.

[0025] exist Figure 2 In FIG. 1 , the component camera 17 is mounted on the base 11 with the imaging optical axis directed upward. The component camera 17 captures an image of the component BH from below in a state where the mounting head 15 that has picked up the component BH is located upward.

[0026] The working device control unit 18 ( Figure 2 ) controls the actions of each part of the working device 2 ( Figure 4). Specifically, the operation device control unit 18 controls the conveying conveyor 12 to carry the substrate KB and position it to the operation position, and controls the component supply operation of the component supply position 13K by the part feeder 13. The operation device control unit 18 controls the movement of the assembly head 15 by the head moving mechanism 14, and controls the picking operation of the assembly head 15 to the component BH.

[0027] The working device control unit 18 also controls the imaging operations of the substrate camera 16 and the component camera 17. The image data obtained by the imaging operation of the substrate camera 16 and the image data obtained by the imaging operation of the component camera 17 are respectively input to the working device control unit 18, and the working device control unit 18 performs image recognition on these image data.

[0028] When some error occurs in the working device 2, the working device control unit 18 of the working device 2 moves the substrate camera 16 and takes an image of the error occurrence site. Thus, error information of the error occurrence site (image of the error occurrence site) is obtained. For example, when pickup misses of components BH from a certain component feeder 13 occur continuously, the component supply position 13K of the component feeder 13 is determined as the error occurrence site, and after moving the substrate camera 16 above the error occurrence site, the substrate camera 16 is made to take an image of the error occurrence site. After obtaining the image of the error occurrence site obtained by the substrate camera 16, the working device control unit 18 of the working device 2 sends the image of the error occurrence site to the server 3 as error information of the error occurrence site (error information).

[0029] The server 3 is connected to the plurality of working devices 2 constituting the working line 2L, and relays the error information respectively transmitted from the plurality of working devices and transmits it to any of the plurality of remote monitoring units 4. The server 3 may be connected to the plurality of working devices 2 by wire or by wireless. The details of the server 3 will be described later.

[0030] exist Figure 1 In the example, the remote monitoring unit 4 functions as a so-called remote terminal and is composed of, for example, a personal computer. The remote monitoring unit 4 can be connected to the server 3 by wire or by wireless. Figure 4 As shown in FIG. 1 , the remote monitoring unit 4 includes a remote monitoring control unit 21, a display unit (display) 22, and an input unit 23. The remote monitoring control unit 21 stores the error information (image of the error occurrence location) of the working device 2 transmitted from the server 3 in the error information storage unit 21a ( Figure 4 ) after which the error message is displayed on the display unit 22.

[0031] Each remote monitoring unit 4 usually has an operator stationed therein, and the operator monitors the occurrence of errors through the display unit 22 and performs operations (error elimination operations) required to eliminate the errors through the input unit 23. The remote monitoring control unit 21 of the remote monitoring unit 4 has a signal transmission unit 21b ( Figure 4 The signal transmission unit 21b transmits an operation signal (elimination operation signal) for an error elimination operation performed from the input unit 23 to the server 3. When the signal transmission unit 21b transmits the elimination operation signal to the server 3, the error information stored in the error information storage unit 21a is deleted.

[0032] When an error occurs in the working device 2 , for example, a pickup error in which the nozzle 15N adsorbs and damages the component BH, the component supply position 13K of the component feeder 13 where the pickup error occurred is identified as the error occurrence site, and this site is photographed by the board camera 16 . Figure 5A This is an example of an image GZ captured by the substrate camera 16 at the component supply position 13K of the parts feeder 13 where such a pickup error has occurred, and displayed on the display unit 22 of the remote monitoring unit 4. In this example, the center position KC of the image GZ coincides with a given position (referred to as a "component suction position") located at the lower end of the nozzle 15N when the component BH located at the component supply position 13K is suctioned.

[0033] exist Figure 5A In the image GZ, the component suction position (center position KC of the image GZ) deviates from the component supply position 13K, so it is expected that a pickup error of the component BH will occur. In this case, the operator performs the operation (error elimination operation) required to make the component suction position consistent with the component supply position 13K from the input unit 23.

[0034] In the above example, the error elimination operation for aligning the position of the lower end of the nozzle 15N with the component supply position 13K is performed from the input unit 23. Thus, a signal for changing the data of the component suction position stored in the working device control unit 18 is sent from the remote monitoring unit 4 to the server 3 as an elimination operation signal, and the server 3 sends the elimination operation signal to the working device control unit 18.

[0035] The working device control unit 18 that has received the cancel operation signal from the remote monitoring unit 4 performs necessary processing according to the received cancel operation signal. Thereby, the error generated in the working device 2 is canceled. Figure 5B The image GZ shows a state where the working device 2 performs an error elimination operation on itself, whereby the component suction position (center position KC of the image GZ) coincides with the component supply position 13K of the parts feeder 13 identified as the error occurrence site, and the generated error is eliminated.

[0036] As described above, the operator of the remote monitoring unit 4 can perform an operation input (error elimination operation input) for eliminating the error from the input unit 23 in response to the error information transmitted from the server 3. In addition, the operator can perform a transmission rejection input for rejecting the transmission of the error information before the error information is transmitted from the server 3. Examples of such transmission rejection input include a case where the operator must leave the remote monitoring unit 4 while waiting for the error information to be transmitted, a case where another operation other than the error elimination operation is required, and the like.

[0037] After the error information is transmitted from the server 3 (the error information is displayed on the display unit 22 of the remote monitoring unit 4), the operator can also perform a task return input to send the task of the error correction operation back to the server 3 without performing the error correction operation for the error information. Examples of performing such a task return input include a case where the operator determines that it is difficult to deal with the error information sent according to his own skills, or a case where an unexpected event occurs after receiving the error information and the operator must move to a place far away from the remote monitoring unit 4.

[0038] When the operator performs a task return input from the remote monitoring unit 4, a signal (task return signal) corresponding to the task return input is sent from the signal sending unit 21b to the server 3. When the signal sending unit 21b sends the task return signal to the server 3, the error information stored in the error information storage unit 21a is deleted.

[0039] exist Figure 4 In the remote monitoring unit 4, the remote monitoring unit 4 is provided with a status registering unit 21c. The status registering unit 21c determines the current state (status) of the remote monitoring unit 4 every several seconds, and based on the determination result, registers the status of the remote monitoring unit 4. The status that can be registered in the remote monitoring unit 4 is either a "resolvable" status in which the operator can respond to the error information, or an "unresolvable" status in which the operator cannot respond to the error information.

[0040] like Figure 6 As shown in the flowchart, the status registration unit 21c first determines whether the corresponding remote monitoring unit 4 holds unprocessed error information in the error information storage unit 21a (step ST1). Here, the state in which the error information storage unit 21a holds unprocessed error information means that after the error information storage unit 21a receives the error information from the server 3, the error information is not deleted (the signal sending unit 21b also does not send the deletion operation signal and the task return signal to the server 3).

[0041] When the status registering unit 21c determines in step ST1 that the remote monitoring control unit 21 corresponding to the status registering unit 21c holds unprocessed error information, the remote monitoring unit 4 determines that the operator cannot further handle the error information, and registers the status of the remote monitoring unit 4 as "unhandled" (step ST2). On the other hand, when it is determined in step ST1 that the remote monitoring control unit 21 does not hold unprocessed error information, it is determined whether there is a transmission rejection input by the operator (step ST3).

[0042] When the status registering unit 21c determines that there is a transmission rejection input, the status of the remote monitoring unit 4 is registered as "incompatible" (step ST2), similarly to the case where it is determined that unprocessed error information is retained. When the status registering unit 21c determines that there is no transmission rejection input in step ST3, the status of the remote monitoring unit 4 is registered as "compatible" (step ST4).

[0043] exist Figure 4 In the example, the server 3 includes a server control unit 31. The server control unit 31 includes an information storage unit 31a, a search unit 31b, and a transmission unit 31c. When the information storage unit 31a receives error information sent from any of the plurality of working devices 2, the error information is stored and saved until the remote monitoring unit 4 performs an error elimination operation for the error information (until an elimination operation signal is received).

[0044] When the information storage unit 31a stores error information transmitted from any of the plurality of working devices 2, the search unit 31b searches for remote monitoring units 4 that are in a state that can be handled by the operator (i.e., the state is registered as "compatible") in order to transmit the error information to the remote monitoring unit 4 that is in a state where the error correction operation can be performed quickly. In this search, the remote monitoring units 4 whose states are "compatible" are detected as remote monitoring units 4 that are in a state that can be handled by the operator with reference to the states of the plurality of remote monitoring units 4.

[0045] The transmission unit 31c transmits (transmits) the error information stored in the information storage unit 31a to the remote monitoring unit 4 detected by the search unit 31b. When a plurality of remote monitoring units 4 in a state that can be handled by the operator are detected by the search performed by the search unit 31b, the error information is transmitted to the remote monitoring unit 4 having the longest elapsed time since the error elimination operation for the last error was performed among the detected plurality of remote monitoring units 4. The elapsed time since the error elimination operation for the last error in the remote monitoring unit 4 can be measured by measuring the elapsed time since the remote monitoring unit 4 sent the last elimination operation signal to the server 3 by a timer (not shown) provided in the server control unit 31.

[0046] Thus, in this embodiment, when receiving error information from any of the plurality of working devices 2, the server 3 searches for a remote monitoring unit 4 in a state that can be handled by an operator, and transmits the error information to the remote monitoring unit 4 detected by the search. Thus, the plurality of error information transmitted from the plurality of working devices 2 is distributed to the plurality of remote monitoring units 4, and the tasks are dispersed. As a result, even when a plurality of errors occur in a concentrated manner at the same time, it is possible to avoid a situation where one operator has to handle all of the plurality of errors.

[0047] When the component assembly operation is performed on the substrate KB using the operation line 2L, the operation device control unit 18 of the operation device 2 first operates the transport conveyor 12 to position the substrate KB at a given operation position. If the substrate KB is positioned at the operation position by the transport conveyor 12, the operation device control unit 18 operates the head moving mechanism 14 to move the assembly head 15 above the substrate KB, and the substrate camera 16 to photograph the substrate KB and identify the substrate KB.

[0048] After recognizing the substrate KB, the operation device control unit 18 activates the component feeder 13 to supply the component BH, and causes the mounting head 15 to repeatedly perform mounting cycles (mounting turns). The mounting head 15 performs the following actions: in one mounting cycle, it moves to the upper part of the component supply position 13K of the component feeder 13 to adsorb (pick up) the component BH to the nozzle 15N; it moves from the upper part of the component feeder 13 to the upper part of the substrate KB through the upper part of the component camera 17; and it lowers the nozzle above the substrate KB to mount the component BH at a given component mounting position on the substrate KB.

[0049] In the assembly cycle, when the assembly head 15 passes above the component camera 17, the component camera 17 takes a picture of the component BH from below, and the operation device control unit 18 recognizes the component BH based on the image capture result. The recognition result of the component BH and the recognition result of the substrate KB are used for alignment when assembling the component BH to the component assembly position. In this way, the assembly cycle of the assembly head 15 is repeatedly performed. If all the necessary components BH are assembled on the substrate KB, the operation device control unit 18 activates the transport conveyor 12 to discharge the substrate KB to the downstream side of the operation device 2.

[0050] Next, the flow of processing when some kind of error occurs in any of the plurality of working devices 2 constituting the working line 2L will be described. Figure 7 The flowchart shows the process flow of the work device control unit 18 when an error occurs in the work device 2. Figure 8The flowchart shows the process flow of the processing performed by the server control unit 31. Fig. 9 The flowchart shows the flow of processing performed by the remote monitoring control unit 21.

[0051] The working device control unit 18 performs a detection operation every several seconds to determine whether an error has occurred in its own working device 2 ( Figure 7 Then, when it is detected that some error has occurred, after determining the location of the error (step ST12), the remote operation mode is entered (step ST13). For example, when an error occurs that the assembly head 15 fails to continuously pick up the component BH from a certain component feeder 13, the operation device control unit 18 determines the component supply position 13K of the component feeder 13 as the error location, interrupts the component assembly operation, and enters the remote operation mode.

[0052] After entering the remote operation mode, the work device control unit 18 moves the board camera 16 to the upper side of the error occurrence site. Then, the board camera 16 is caused to photograph the error occurrence site to obtain error information (step ST14). If the error information is obtained, the obtained error information (image of the error occurrence site) is sent to the server 3 (step ST15).

[0053] The server 3 performs a detection operation (in the search unit 31b) every several seconds to determine whether error information has been received from the operation device 2. Figure 8 In the detection operation, when it is detected that error information transmitted from the working device 2 is received, the search unit 31b performs a search for a remote monitoring unit 4 in a state that can be handled by the operator from among the plurality of remote monitoring units 4 (step ST22).

[0054] In the search of step ST22, the search unit 31b refers to the status registered in each remote monitoring unit 4. Then, the remote monitoring unit 4 whose status is registered as "available" is determined to be a remote monitoring unit 4 in a status that can be handled by the operator. In this search, since the remote monitoring unit 4 that has previously inputted a rejection of transmission by the operator has registered the status as "unavailable", the server 3 treats the remote monitoring unit 4 that has rejected transmission as not being a remote monitoring unit 4 that can be handled by the operator in the search of step ST22.

[0055] The server 3 transmits the error information to the remote monitoring unit 4 detected in the search of step ST22 (step ST23). In step ST23, the error information is transmitted to the remote monitoring unit 4 whose elapsed time since the error correction operation for the previous error was performed is the longest among one or more remote monitoring units 4 detected as the remote monitoring units 4 whose status is registered as "available" in step ST22.

[0056] Each remote monitoring unit 4 performs a detection operation every several seconds to determine whether it has received error information transmitted from the server 3 ( Fig. 9 In this detection operation, when the remote monitoring unit 4 detects that error information transmitted from the server 3 is received, the remote monitoring unit 4 causes the display unit 22 to display the received error information (step ST32). Thus, the operator can view the error information displayed on the display unit 22 and perform an operation to eliminate the error that occurred in the working device 2.

[0057] After the remote monitoring unit 4 displays the error information on the display unit 22 in step ST32, it enters a waiting state for input (error elimination operation input or task return input) by the operator (step ST33). Then, if there is input by the operator, the remote monitoring unit 4 determines whether the input is an error elimination operation input (step ST34). If it is determined that the input is an error elimination operation input, it sends an operation signal (elimination operation signal) corresponding to the error elimination operation input to the server 3 (step ST35), and then returns to step ST31. On the other hand, in step ST34, if it is determined that the input is not an error elimination operation input (it is a task return input), the remote monitoring unit 4 sends a task return signal to the server 3 (step ST36), and then returns to step ST31.

[0058] After the server 3 transmits the error information to the remote monitoring unit 4 in the aforementioned step ST23, or when the server 3 does not receive the error information in the aforementioned step ST21, it determines whether a task return signal ( Figure 8 Then, when a task return signal is received from any of the plurality of remote monitoring units 4, the process returns to step ST22, and the remote monitoring units 4 other than the remote monitoring unit 4 that sent the task return signal are searched again. Then, the remote monitoring unit 4 detected in the re-search re-sends (transmits) the erroneous information (step ST23).

[0059] Thus, in the present embodiment, the operator of the remote monitoring unit 4 can perform a task return input from the remote monitoring unit 4 to send the task of the error elimination operation back to the server 3 without performing the error elimination operation for the error information transmitted from the server 3. When the task return input is performed from the remote monitoring unit 4, the server 3 performs a search again by the search unit 31b for other remote monitoring units 4 other than the remote monitoring unit 4 that performed the task return input. Therefore, the operator of the remote monitoring unit 4 can transfer the task that is considered difficult for him / her to handle to other operators by performing the task return input, and can smoothly eliminate the error of the entire work line 2L.

[0060] After resending the erroneous information, the server 3 proceeds to step ST24 to determine whether a task return signal is received from another remote monitoring unit 4. Then, if a task return signal is received from another remote monitoring unit 4, the server 3 proceeds to step ST22 again. If a task return signal is not received from another remote monitoring unit 4, the server 3 determines whether a deletion operation signal is received from any of the multiple remote monitoring units 4 (step ST25). Then, if a deletion operation signal is received from any of the multiple remote monitoring units 4, the server 3 sends a deletion operation signal to the operating device 2 corresponding to the received deletion operation signal (step ST26), and then returns to step ST21. On the other hand, if a deletion operation signal is not received in step ST25, the server 3 directly returns to step ST21.

[0061] In the above-mentioned step ST15, if each operation device 2 sends an error message to the server 3, it enters the waiting state for receiving the deletion operation signal ( Figure 7 Then, if a cancellation operation signal is received from the server 3, the operation device 2 performs the necessary processing to cancel the error that occurred in the operation device 2 according to the received cancellation operation signal (step ST17). After the operation device 2 performs the processing to cancel the error that occurred in itself according to the received cancellation operation signal, it exits from the remote operation mode (step ST18). Then, it returns to step ST11 and performs the detection operation to see if an error has occurred in itself again.

[0062] As described above, in the remote operation system 1 of the present embodiment, the information of errors respectively occurring in the plurality of working devices 2 is relayed and transmitted to the server 3 of any remote monitoring unit among the plurality of remote monitoring units, and the information of the plurality of errors received from the plurality of working devices 2 is distributed to the plurality of remote monitoring units 4 for transmission. Therefore, the plurality of errors occurring in the plurality of working devices 2 are dispersed to the plurality of remote monitoring units 4, and the plurality of errors occurring at the same time are not concentrated on one operator as in the past. As a result, the error elimination process is carried out smoothly, and the overall production rhythm of the working line 2L is unlikely to be slowed down. That is, according to the remote operation system 1 of the present embodiment, the plurality of errors occurring at the same time as the plurality of working devices 2 can be eliminated without delay.

[0063] The embodiments of the present disclosure have been described so far, but the present invention is not limited to the aforementioned contents, and various modifications are possible. For example, in the aforementioned embodiments, when the server 3 detects through search a plurality of remote monitoring units 4 in a state that can be handled by an operator, the server 3 transmits error information to the remote monitoring unit 4 that has the longest elapsed time since the error correction operation for the last error was performed among the detected plurality of remote monitoring units 4. However, instead of such a criterion, or on the basis of such a criterion, a criterion that considers the operating ability of the operator (a criterion that a remote monitoring unit 4 operated by an operator with a higher operating ability sends more tasks) may be applied to distribute the error information.

[0064] In addition, in the aforementioned embodiment, a plurality of work devices 2 constitute the work line 2L, but the work devices 2 to which the present invention is applied do not necessarily constitute the work line 2L. In addition, in the aforementioned embodiment, the work devices 2 are component mounting devices that mount components BH on the substrate KB to which the present invention is applied, but the work devices 2 to which the present invention is applied are not limited to component mounting devices.

[0065] According to the present disclosure, a plurality of errors occurring at the same time as a plurality of working devices can be eliminated without delay.

When receiving error information from any of the plurality of working devices, the server searches for a remote monitoring unit that is in a state that can be handled by an operator from among the plurality of remote monitoring units, and distributes the plurality of error information received from the plurality of working devices to the plurality of remote monitoring units by sending the error information to the remote monitoring units detected by the search. When the server detects a plurality of remote monitoring units in a situation that can be handled by the operator, the server sends error information to the remote monitoring unit among the plurality of remote monitoring units that has had the longest elapsed time since an error correction operation was performed for the last error.

2. The remote operation system according to claim 1, wherein: The operator of the remote monitoring unit can make a transmission rejection input from the remote monitoring unit to reject the server from transmitting the erroneous information, and the server treats the remote monitoring unit that has made the transmission rejection input as a situation that cannot be handled by the operator in the search.

3. The remote operation system according to claim 1, wherein: The operator of the remote monitoring unit can perform a task return input from the remote monitoring unit, wherein the task return input returns a task of performing an error correction operation to the server without performing an error correction operation on the error information transmitted from the server. When the task return input is made from the remote monitoring unit, the server performs the search again with respect to other remote monitoring units except the remote monitoring unit that made the task return input.

4. The remote operation system according to claim 1, wherein: The working device is a component mounting device that mounts a component on a substrate that is a working target.
