Embodiments of the present disclosure will be described below with reference to the drawings. FIG. 1 shows a configuration diagram of a work system 1 according to an embodiment of the present disclosure. FIG. 2 shows the flow of information in the work system 1. As shown in FIG. The work system 1 includes a work line 2L composed of a plurality of work devices 2, a server 3 as a relay section, and a plurality of remote monitoring sections 4. As shown in FIG.

FIG. 3 is a side view of the work device 2 that configures the work system 1 according to one embodiment of the present disclosure. Each work device 2 constituting the work line 2L is, in the present embodiment, a component mounting device that performs work (component mounting work) to mount the component BH on the board KB. The work device 2 includes a base 11, a conveyor 12, a tape feeder 13, a head moving mechanism 14, a mounting head 15, a board camera 16, an input section 17 and an output section 18, as shown in FIG. The input unit 17 and the output unit 18 may be configured as part of the functions of a touch panel, for example.

FIG. 4 is a perspective view of part of the working device 2 according to one embodiment of the present disclosure. In FIG. 3, the transport conveyor 12 extends horizontally on the base 11 and transports the substrate KB horizontally from one end to the other end. The tape feeder 13 draws out and conveys the carrier tape CT wound around the reel RL by a built-in sprocket 13S (see also FIG. 4).

A large number of parts BH are enclosed in a line in the carrier tape CT. The tape feeder 13 supplies the component BH to the component supply position 13K by feeding the carrier tape CT toward the transport conveyor 12 side.

The head moving mechanism 14 consists of, for example, an XY table mechanism, and moves the mounting head 15 within the horizontal plane. The mounting head 15 has a plurality of downwardly extending nozzles 15N.

In FIGS. 3 and 4, the substrate camera 16 is attached to the mounting head 15 with the imaging optical axis facing downward. The board camera 16 is attached to the mounting head 15 and is moved in the horizontal plane together with the mounting head 15 by the head moving mechanism 14 .

The input unit 17 is operated by the field worker OP1 (FIGS. 1 and 2). Here, the "field worker" refers to a worker who directly operates the work device 2 manually to perform necessary work.

FIG. 5 is a block diagram showing the control system of the work system 1 according to one embodiment of the present disclosure. In FIG. 5, a work device control section 19 (see also FIG. 3), which is a control section of the work device 2, controls each operation of the transport conveyor 12, the tape feeder 13, the head moving mechanism 14, and the mounting head 15. FIG. The transport conveyor 12 is controlled by the work device controller 19 to transport and position the board KB, and each tape feeder 13 is controlled by the work device controller 19 to supply the component BH to the component supply position 13K. A head moving mechanism 14 moves the mounting head 15 . The mounting head 15 picks up the component BH with the nozzle 15N (FIG. 4).

In FIG. 5, the work device control unit 19 controls the substrate camera 16. The substrate camera 16 is controlled by the work device control unit 19 to image the substrate KB positioned by the transport conveyor 12 .

The work device control unit 19 is communicably connected to the input unit 17 and the output unit 18 respectively. Information input from the input unit 17 by the field worker OP1 is sent to the work device control unit 19 . The work device control section 19 operates based on the information input from the input section 17 . Further, the work device control unit 19 outputs information necessary for the field worker OP1 to the output unit 18 .

When the work device 2 performs the component mounting work, first, the board KB is carried in by the transport conveyor 12 and positioned at the work position. When the board KB is positioned at the working position, the head moving mechanism 14 is activated to move the mounting head 15 above the board KB, thereby allowing the board camera 16 to image the board KB. Image data of the board KB captured by the board camera 16 is sent to the work device control unit 19, and the work device control unit 19 recognizes the board KB.

When the board KB is recognized, the tape feeder 13 operates to supply the component BH to the component supply position 13K. The mounting head 15 moves between the top of the tape feeder 13 and the top of the substrate KB to repeatedly perform the component mounting operation. In the component mounting operation, the mounting head 15 picks up the component BH supplied by the tape feeder 13 with the nozzle 15N, moves above the board KB, and then mounts the component BH at a predetermined position on the board KB.

The mounting head 15 repeats the component mounting operation, and when all the components have been mounted, the transport conveyor 12 carries out the board KB from the working position. This completes the component mounting work for each board KB.

The work device 2 performs the component mounting work according to the procedure described above, but some kind of error may occur in the process. The work system 1 according to the present embodiment has an error elimination function that, when an error occurs in any one of the plurality of work devices 2 constituting the work line 2L, takes measures to eliminate the error. The explanation is given below.

The work device control unit 19 of each work device 2 includes an error information acquisition unit 21, as shown in FIG. The work device 2 suspends all or part of the component mounting work that is being executed when an error occurs in itself. The error information acquisition unit 21 acquires, as "error information", information on the location where an error has occurred (error occurrence location), information on the type and content of the error that has occurred, and the like, after the operation of the component mounting work is interrupted. Here, if the identified error occurrence location can be imaged by the board camera 16, the board camera 16 is caused to image the error occurrence location. For example, when the mounting head 15 fails to pick up a component BH from a certain tape feeder 13 a fixed number of times in succession, the component supply position 13K of the tape feeder 13 is specified as an error occurrence location, and the error occurrence is determined. A still image or moving image of the location is captured by the substrate camera 16 .

In FIG. 5 , the work device control unit 19 of each work device 2 includes a notification destination determination unit 22 . The notification destination determination unit 22 determines the notification destination of the error information acquired by the error information acquisition unit 21 . Specifically, the notification destination determining unit 22 determines which of the on-site worker OP1 and the remote operator OP2 is to be the transmission destination of the error information according to the type of error that has occurred. Here, the “remote operator OP2” refers to an operator who operates each remote monitoring unit 4 .

In FIG. 5, the work device control unit 19 of each work device 2 has an error information transmission unit 23 . The error information transmission unit 23 transmits the error information acquired by the error information acquisition unit 21 to the notification destination determined by the notification destination determination unit 22 . Specifically, when the notification destination determination unit 22 determines the error information notification destination to be the field worker OP1, the error information transmission unit 23 causes the output unit 18 to output (display) the content of the error information. When the error information is output to the output unit 18, the field worker OP1 manually resolves the error directly on the work device 2 according to the contents of the output error information (error resolution work). I do.

On the other hand, when the notification destination determination unit 22 determines the destination of the error information to be the remote operator OP2, the error information transmission unit 23 transmits the error information to the server 3 (Fig. 2). At this time, the error information transmitted by the error information transmission unit 23 to the server 3 includes the image data (still image data or moving image data) of the error occurrence location acquired by the error information acquisition unit 21 .

In FIG. 5, the server 3 comprises a storage section 31, a selection section 32 and a transfer section 33. The storage unit 31 stores the work skill level of each remote operator OP2 for error resolution work for each type of error.

When error information is transmitted from the work device 2, the selection unit 32 selects one remote monitoring unit 4 as the transmission (transfer) destination of the error information. At this time, the selection unit 32 selects the remote operator OP2 who can most quickly perform the error resolution work based on the work skill level of each remote operator OP2 for each error type stored in the storage unit 31, for example. The remote monitoring unit 4 operated by the extracted remote operator OP2 is selected as the transmission destination of the error information.

The transfer unit 33 transmits (transfers) the error information transmitted from the work device 2 to one remote monitoring unit 4 selected by the selection unit 32 .

In FIG. 1, each remote monitoring unit 4 is composed of, for example, a personal computer. Each remote monitoring unit 4 is connected to the server 3 by wire or wirelessly. Each remote monitoring unit 4 includes a remote monitoring control unit 41, a display device 42 and an input device 43, as shown in FIG.

　In FIG. 5, the remote monitoring control section 41 of each remote monitoring section 4 includes an error information receiving section 41a. The error information receiving unit 41a receives the error information transmitted (transferred) from the server 3, and causes the display device 42 to display the contents of the received error information.

6A and 6B are diagrams showing an example of a captured image of an error occurrence location displayed on the display device 42 of the remote monitoring unit 4 included in the work system 1 according to the embodiment of the present disclosure. FIG. 6A shows a captured image of an error occurrence location as an example of error information displayed on the display device 42. FIG. The captured image of the error occurrence location shown in FIG. 6A shows an area including the component supply position 13K of the tape feeder 13 in the case where the pickup error of the component BH described above occurs. The position matches the position of the lower end of the nozzle 15N (nozzle lower end position KC). When the captured image of the error occurrence location is displayed on the display device 42, the remote operator OP2 performs an error elimination operation from the input device 43 while viewing the image.

The nozzle lower end position KC should originally match the component supply position 13K, but in the image of FIG. 6A in which an error has occurred, the nozzle lower end position KC and the component supply position 13K do not match. In this case, the remote operator OP2 moves the position of the mounting head 15 during component pickup so that the nozzle lower end position KC coincides with the component supply position 13K of the tape feeder 13 . Specifically, an offset for moving the position of the mounting head 15 during component pickup is performed so that the difference between the nozzle lower end position KC and the component supply position 13K in the image of FIG. 6A is canceled and the state of FIG. 6B is obtained. The amount (direction of movement and amount of movement) is input from the input device 43 .

　In FIG. 5, the remote monitoring control section 41 of each remote monitoring section 4 includes a resolution operation information transmission section 41b. The resolving operation information transmitting unit 41 b transmits information (resolving operation information) of an error resolving operation input from the input device 43 to the server 3 . When the server 3 receives the cancellation operation information, the transfer unit 33 transmits (transfers) the received cancellation operation information to the work device 2 which is the transmission source of the error information.

In FIG. 5 , the work device control unit 19 of each work device 2 is provided with a cancellation operation information reception unit 24 . The cancellation operation information receiving section 24 receives the cancellation operation information transmitted from the remote monitoring section 4 (FIG. 2). The work device 2 that has received the resolving operation information resolves the error by operating (remotely operated by the remote operator OP2) based on the received resolving operation information. When the error is resolved, the work device control unit 19 cancels the interrupted state of the component mounting work and restarts the component mounting work.

The error that occurred in the work device 2 is resolved in this way, and the interrupted component mounting work is resumed. In the work system 1 according to the present embodiment, it is determined that the destination of the notification of the error information of the error that has occurred is the site worker OP1, and the site worker OP1 who performs the operation to eliminate the error can If the error cannot be resolved, the remote operator OP2 can be requested to support the work. The explanation is given below.

When the field worker OP1 requests the remote operator OP2 to support the work, he/she inputs the content of the requested work using the above-described input unit 17 provided in the work device 2 (request input step). At this time, the input unit 17 functions as a request input unit.

In FIG. 5, the work device control unit 19 of each work device 2 includes a request information transmission unit 25 . The request information transmitting unit 25 transmits to the server 3 information (request information) on the content of the work support request input by the field worker OP1 (request information transmission step; FIG. 2).

When the server 3 receives the request information from the work device 2, the selection unit 32 selects one remote monitoring unit 4 as the transmission (transfer) destination of the request information. At this time, based on the work skill level of each remote operator OP2 for each type of error stored in the storage unit 31, the selection unit 32 selects the remote operators operated by the remote operators OP2 who can respond most quickly to the support request. The monitoring unit 4 is selected as the transmission destination of the request information. When one remote monitoring unit 4 is selected by the selecting unit 32, the transfer unit 33 transmits (transfers) the request information received from the working device 2 to the selected one remote monitoring unit 4 (FIG. 2).

　In FIG. 5, the remote monitoring control section 41 of each remote monitoring section 4 includes a request information receiving section 41c. The request information receiving unit 41c receives the request information transmitted from the server 3 (request information receiving step; FIG. 2), and causes the display device 42 to display the contents of the received request information.

Based on the content of the request information displayed on the display device 42, the remote operator OP2 of the remote monitoring unit 4 inputs a response (support response) to the support request required by the field worker OP1 from the input device 43 (response input process). At this time, the input device 43 functions as a response input section for the remote operator OP2 to input a support response to the support request sent from the request information transmission section 25 of the work device 2 .

5, the remote monitoring control unit 41 of each remote monitoring unit 4 includes a response information transmission unit 41d. The response information transmission unit 41d transmits support response information (response information) input from the input device 43 to 3 (response information transmission step; FIG. 2). When the server 3 receives the response information, the transfer unit 33 transmits (transfers) the received response information to the work device 2 that is the source of the request information (FIG. 2).

5, the work device control unit 19 of each work device 2 includes a response information reception unit 26. FIG. The response information receiving unit 26 receives response information from the remote monitoring unit 4 that the work device 2 has received through the server 3 (response information receiving step; FIG. 2), and outputs the content of the received response information to the output unit 18. (display) (response content output step). At this time, the output unit 18 functions as a response content output unit that outputs the content of the support response based on the support response information (response information) transmitted from the response information transmission unit 41 d of the remote monitoring unit 4 .

By outputting the content of the response information to the output unit 18, the field worker OP1 can obtain knowledge about the solution of the error that he did not have from the remote operator OP2. Therefore, even if the on-site worker OP1 cannot solve the error based on his/her own knowledge, he/she can quickly solve the error without referring to the manual or the like, and the efficiency of the error solution is improved. improves.

As described above, the work system 1 in the present embodiment includes a request input unit (input unit 17 ), a request information transmission unit 25 for transmitting the information of the support request input from the request input unit (request information transmission step), and the remote operator based on the information of the support request transmitted from the request information transmission unit 25 A response input unit (input device 43) for inputting a support response (response input step) that is a response to the support request by OP2, and transmitting information of the support response input from the response input unit (response information transmission step) and a response content output unit (output unit 18 ).

Therefore, when the field worker OP1 feels that he/she lacks skill while performing the error resolution work, he/she can request the remote operator OP2 for support of the work, and upon receiving the support response from the remote operator OP2, the error resolution work can be performed. can be completed. Thus, according to the work system 1 (or the error elimination method by the work system 1 having the request input process, the request information transmission process, the response input process, the response information transmission process, and the response content output process) in the present embodiment, Even if the field worker OP1 lacks the skill, he or she can quickly solve the error without referring to the manual, and the loss of time can be greatly reduced.

As described above, according to the work system 1 (the error resolution method in the work system 1) according to the present embodiment, the field worker OP1 operates the remote monitoring unit 4 when he/she feels lack of skill in the error resolution operation. It is possible to request the remote operator OP2 for work support, and to receive a support response from the remote operator OP2, so that the error resolution work can be performed quickly. Therefore, even if the field worker OP1 lacks the skill, he or she can perform the error elimination work without referring to the manual, thereby greatly reducing the time loss and improving the work efficiency of the error elimination work.
