Detailed Description

In a conventional remote operation system, when a plurality of errors occur collectively in a plurality of working devices at the same time, one operator must perform a process of removing the plurality of errors quickly and continuously. Therefore, not only the workload of the operator becomes excessive, but also the waiting time for error removal processing increases cumulatively, and the productivity of the entire line may be lowered.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Fig. 1 shows a remote operation system 1 in one embodiment of the present disclosure. The remote operation system 1 includes a plurality of work apparatuses 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 have occurred in each of the plurality of work apparatuses 2, and transmits the information to any one of the plurality of remote monitoring units 4. Then, an error removal operation for removing the error can be remotely performed from the remote monitoring unit 4 that has received the transmission of the error information. In the present embodiment, each working device 2 is a component mounting device that mounts a component BH (see fig. 2, for example) on a substrate KB to be worked. The plurality of working devices 2 are arranged in series to form a working line 2L.

In fig. 2, each working device 2 includes a base 11, a transfer 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 extends on the base 11 in the left-right direction (X-axis direction) of the base 11, and receives the substrate KB sent from the upstream side and positions the substrate KB at a predetermined working position. After the component mounting operation described later is performed on the substrate KB, the substrate KB is transported to the downstream side and discharged.

In fig. 2, the parts feeder 13 is a tape feeder, and pulls out the carrier tape CT wound around the reel RL by a built-in sprocket (スプ, gate ケット)13S (see also fig. 3), and conveys the carrier tape CT in the front-rear direction (Y-axis direction) of the base 11, and supplies the parts BH to a parts supply position 13K provided at an end portion on the side of the conveying conveyor 12. The head moving mechanism 14 is constituted by, for example, an XY stage mechanism, and moves the fitting head 15 in a horizontal plane. The mounting head 15 has a plurality of nozzles 15N extending downward in the vertical direction (Z-axis direction).

The mounting head 15 can raise and lower each nozzle 15N in the Z-axis direction. Further, the fitting head 15 can generate a vacuum suction force to the lower end of each nozzle 15N. After the nozzle 15N is positioned above the component supply position 13K of the parts feeder 13, the mounting head 15 lowers the nozzle 15N, and generates a vacuum suction force at the lower end of the nozzle 15N to suck the component BH and pick up the component BH (fig. 3).

In fig. 2 and 3, the board camera 16 is attached to the mounting head 15 in a posture in which an imaging optical axis is directed downward. The substrate camera 16 moves in the horizontal plane inward integrally with the mounting head 15, and photographs the substrate KB positioned at the working position by the transport conveyor 12 from above. When an error occurs in the working device 2, the board camera 16 photographs a portion where the error has occurred (error occurrence portion) from above.

In fig. 2, the component camera 17 is attached to the base 11 in a posture in which the imaging optical axis is directed upward. The component camera 17 photographs the component BH from below with the mounting head 15 that picked up the component BH positioned above.

A work implement control unit 18 (fig. 2) as a control unit of the work implement 2 controls the operations of the respective units of the work implement 2 (fig. 4). Specifically, the working device control unit 18 controls the conveying operation of the conveying conveyor 12 for the substrate KB and the positioning operation thereof to the working position, and controls the component feeding operation of the component feeder 13 for the component feeding position 13K. The working device control unit 18 controls the movement operation of the head moving mechanism 14 with respect to the mounting head 15, and controls the picking operation of the component BH by the mounting head 15.

The work apparatus control unit 18 also controls the imaging operation of the board camera 16 and the component camera 17. Image data obtained by the image capturing operation of the board camera 16 and image data obtained by the image capturing operation of the component camera 17 are input to the work apparatus control unit 18, and the work apparatus control unit 18 performs image recognition on these image data.

When some error occurs in the work equipment 2, the work equipment control unit 18 of the work equipment 2 moves the board camera 16 and takes an image of the error occurrence portion. This obtains error information (an image of the error-occurring portion) of the error-occurring portion. For example, when a pick-up error (pick up miss) of a component BH from a certain component feeder 13 occurs continuously, the component feeding position 13K of the component feeder 13 is determined as an error occurrence portion, and after the substrate camera 16 is moved to above the error occurrence portion, the error occurrence portion is imaged by the substrate camera 16. The work device control unit 18 of the work device 2 acquires the image of the error occurrence portion acquired by the board camera 16, and then transmits the image of the error occurrence portion to the server 3 as error information (error information) of the error occurrence portion.

The server 3 is connected to the plurality of work apparatuses 2 constituting the work line 2L, and relays error information transmitted from each of the plurality of work apparatuses to one of the plurality of remote monitoring units 4. The server 3 may be connected to each of the plurality of work apparatuses 2 by a wire or wirelessly. Details of the server 3 will be described later.

In fig. 1, the remote monitoring unit 4 functions as a so-called remote terminal, and is constituted by, for example, a personal computer. The remote monitoring unit 4 may be connected to the server 3 by wire or wirelessly. As shown in fig. 4, 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 portion) of the work equipment 2 sent from the server 3 in the error information storage unit 21a (fig. 4), and then causes the display unit 22 to display the error information.

Each remote monitoring unit 4 normally has one operator resident thereon, and the operator monitors the occurrence of an error via the display unit 22 and performs an operation (error removal operation) necessary for removing the error from the input unit 23. The remote monitoring control unit 21 of the remote monitoring unit 4 includes a signal transmission unit 21b (fig. 4). The signal transmitting section 21b transmits an operation signal (erasing operation signal) for the error erasing operation performed from the input section 23 to the server 3. When the signal transmitting section 21b transmits the cancel operation signal to the server 3, the error information stored in the error information storing section 21a is deleted.

When an error occurred in the working device 2 is, for example, a pickup error in which the nozzle 15N sucks and damages the component BH, the component feeding position 13K of the part feeder 13 in which the pickup error occurred is determined as an error occurrence portion, and the error occurrence portion is imaged by the substrate camera 16. Fig. 5A shows an example of an image GZ of the component feeding position 13K of the component feeder 13 where such a pickup error has occurred, which is captured by the board camera 16 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 "component suction position") located at the lower end of the nozzle 15N when sucking the component BH located at the component supply position 13K.

In the image GZ of fig. 5A, since the component suction position (the center position KC of the image GZ) is deviated from the component feeding position 13K, it is expected that a pickup error of the component BH will occur. In this case, the operator performs an operation (error elimination operation) necessary to match the component suction position with the component supply position 13K from the input section 23.

In the above example, the input unit 23 performs the error correction operation to match the position of the lower end of the nozzle 15N with the component supply position 13K. Thus, a signal for changing the data of the component suction position stored in the work apparatus control unit 18 is transmitted from the remote monitoring unit 4 to the server 3 as a removal operation signal, and the server 3 transmits the removal operation signal to the work apparatus control unit 18.

The work apparatus control unit 18 that has received the cancel operation signal from the remote monitoring unit 4 performs a desired treatment based on the received cancel operation signal. This eliminates an error generated in the working device 2. Fig. 5B shows an image GZ in the following state: the work device 2 performs the error correction operation on itself, and thereby the component suction position (the center position KC of the image GZ) coincides with the component feeding position 13K of the part feeder 13 specified as the error occurrence portion, and the generated error is corrected.

As described above, the operator of the remote monitoring unit 4 can perform the operation input (error removal operation input) for removing the error from the input unit 23 with respect to the error information transmitted from the server 3, and can perform the transmission rejection input for rejecting the transmission of the error information before the error information is transmitted from the server 3. Examples of such a transmission rejection input include a case where the operator has to leave the remote monitoring unit 4 while waiting for transmission of error information, a case where another job different from the job for error correction needs to be performed, and the like.

The operator can also perform a task return input of returning the task of the error correction operation to the server 3 without performing the error correction operation for the error information after transmitting the error information from the server 3 (the error information is displayed on the display unit 22 of the remote monitoring unit 4). Examples of such a task return input include: the operator determines that it is difficult to deal with the transmitted error information according to his or her own skill, or that the operator should move to a place distant from the remote monitoring unit 4 due to a sudden occurrence after receiving the error information.

When the operator makes a task return input from the remote monitoring unit 4, a signal (task return signal) corresponding to the task return input is transmitted from the signal transmitting unit 21b to the server 3. When the signal transmitting unit 21b transmits the job returning signal to the server 3, the error information stored in the error information storage unit 21a is deleted.

In fig. 4, the remote monitoring unit 4 includes a status registration unit 21 c. The status registering unit 21c determines the current status of the remote monitoring unit 4 every several seconds, and registers the status of the remote monitoring unit 4 based on the determination result. The status that can be registered in the remote monitoring unit 4 is either a "available" status in which the operator can handle the error information or an "unavailable" status in which the operator cannot handle the error information.

As shown in the flowchart of fig. 6, the status registration unit 21c first determines whether or not the corresponding remote monitoring unit 4 holds unprocessed error information in the error information storage unit 21a (step ST 1). Here, the state in which the error information storage unit 21a holds unprocessed error information means a state in which the error information storage unit 21a has not deleted the error information after receiving the error information from the server 3 (a state in which the signal transmission unit 21b has not transmitted the erasure operation signal and the job return signal to the server 3).

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 "non-response" (step ST 2). On the other hand, when it is determined in step ST1 that the unprocessed error information is not held in the remote monitoring control unit 21, it is determined whether or not there is a transmission rejection input by the operator (step ST 3).

When determining that there is a transmission rejection input, the status registration unit 21c registers the status of the remote monitoring unit 4 as "no response" in the same manner as when determining that the unprocessed error information is held (step ST 2). If it is determined in step ST3 that the transmission rejection input has not been made, the status registration unit 21c registers the status of the remote monitoring unit 4 as "available" (step ST 4).

In fig. 4, the server 3 has a server control unit 31. The server control unit 31 includes an information storage unit 31a, a search unit 31b, and a transmission unit 31 c. When receiving error information transmitted from any of the plurality of working devices 2, the information storage unit 31a stores the error information and stores the error information until the remote monitoring unit 4 performs an error cancellation operation for the error information (until the cancellation operation signal is received).

When the information storage unit 31a stores error information transmitted from any of the plurality of working apparatuses 2, the search unit 31b searches the remote monitoring unit 4 for detecting a situation that the operator can handle (that is, a situation registered as "capable of handling") in order to transmit the error information to the remote monitoring unit 4 that is in a situation in which the error can be promptly removed. In this search, the status of each of the plurality of remote monitoring units 4 is referred to, and the remote monitoring unit 4 whose status is "compatible" is detected as the remote monitoring unit 4 in a status that can be handled by the operator.

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 31 b. 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, error information is transmitted to the remote monitoring unit 4 that has the longest elapsed time since the error removal operation for the previous error is performed, among the plurality of detected remote monitoring units 4. The elapsed time since the error cancellation operation was performed on the previous error in the remote monitoring unit 4 can be measured by a timer, not shown, included in the server control unit 31 measuring the elapsed time since the remote monitoring unit 4 transmitted the previous cancellation operation signal to the server 3.

As described above, in the present embodiment, when receiving error information from any of the plurality of work apparatuses 2, the server 3 searches for the remote monitoring unit 4 in a state that can be handled by the operator, and transmits the error information to the remote monitoring unit 4 detected by the search. Thus, the plurality of pieces of error information transmitted from the plurality of work apparatuses 2 are distributed to the plurality of remote monitoring units 4, and the tasks are distributed. As a result, even when a plurality of errors occur collectively at the same time, it is possible to avoid a situation in which one operator handles all of the plurality of errors.

When the component mounting work is performed on the substrate KB in the work line 2L, the work apparatus control unit 18 of the work apparatus 2 first operates the transport conveyor 12 to position the substrate KB at a predetermined work position. When the substrate KB is positioned at the working position by the transport conveyor 12, the working device control unit 18 operates the head moving mechanism 14, moves the mounting head 15 above the substrate KB, and causes the substrate camera 16 to photograph the substrate KB to recognize the substrate KB.

After recognizing the substrate KB, the work apparatus control section 18 operates the part feeder 13, causes the part feeder 13 to feed the component BH, and causes the assembly head 15 to repeatedly execute an assembly cycle (mounting turn). The fitting head 15 performs the following operations: an operation of moving the component feeder 13 to a position above the component feeding position 13K and adsorbing (picking) the component BH to the nozzle 15N in 1 assembly cycle; an operation of moving the component feeder 13 from above to above the substrate KB through the component camera 17; and an operation of lowering the nozzle above the substrate KB to mount the component BH at a predetermined component mounting position on the substrate KB.

In the assembly cycle, when the assembly head 15 passes above the component camera 17, the component camera 17 photographs the component BH from below, and the work apparatus control portion 18 recognizes the component BH based on the result of the imaging. The recognition result of the component BH and the recognition result of the substrate KB are used for alignment when the component BH is mounted at the component mounting position. In this way, the assembly cycle of the assembly head 15 is repeated, and if all the necessary components BH are assembled on the substrate KB, the working device control unit 18 operates the transport conveyor 12 to discharge the substrate KB to the downstream side of the working device 2.

Next, a flow of processing in a case where some error occurs in any of the plurality of work apparatuses 2 constituting the work line 2L will be described. Fig. 7 is a flowchart showing a process performed by the work apparatus control unit 18 when an error has occurred in the work apparatus 2, fig. 8 is a flowchart showing a process performed by the server control unit 31, and fig. 9 is a flowchart showing a process performed by the remote monitoring control unit 21.

The work device control unit 18 performs a detection operation of whether or not an error has occurred in the work device 2 of its own at intervals of several seconds (step ST11 of the flowchart shown in fig. 7). Then, when it is detected that some error has occurred in itself, after the occurrence location of the error is determined (step ST12), the remote operation mode is entered (step ST 13). For example, when an error occurs such that the operation of the assembly head 15 to pick up the components BH from a certain part feeder 13 is continuously failed, the work device control section 18 specifies the component feeding position 13K of the part feeder 13 as an error occurrence position, and after the component assembly work is interrupted, enters the remote operation mode.

After entering the remote operation mode, the work equipment control unit 18 moves the board camera 16 above the error occurrence portion. Then, the board camera 16 is caused to capture an image of the error occurrence portion, thereby acquiring error information (step ST 14). If the error information is acquired, the acquired error information (image of the error occurrence portion) is transmitted to the server 3 (step ST 15).

The server 3 performs a detection operation of detecting whether or not error information is received from the work apparatus 2 every several seconds in the search unit 31b (step ST21 of the flowchart shown in fig. 8). In the detection operation, when it is detected that the error information transmitted from the work implement 2 is received, the search unit 31b performs a search for the remote monitoring unit 4 that detects a situation that can be handled by the operator from among the plurality of remote monitoring units 4 (step ST 22).

The search unit 31b refers to the status registered in each remote monitoring unit 4 in the search at step ST 22. Then, the remote monitoring unit 4 whose status is registered as "available" determines that the remote monitoring unit 4 is in a status that can be handled by the operator. In this search, since the remote monitoring unit 4 that has made the transmission rejection input in advance by the operator registers the situation as "unsuitable", the server 3 performs processing in the search of step ST22 with regard to the remote monitoring unit 4 that has made the transmission rejection as a remote monitoring unit 4 that is not available for the operator.

The server 3 transmits error information to the remote monitoring unit 4 detected in the search at step ST22 (step ST 23). In step ST23, in step ST22, error information is transmitted to the remote monitoring unit 4 whose elapsed time since the error removal operation for the previous error was performed is longest among the one or more remote monitoring units 4 detected as the remote monitoring units 4 whose status is registered as "available".

Each remote monitoring unit 4 performs a detection operation of detecting whether or not the error information transmitted from the server 3 is received every several seconds (step ST31 of the flowchart shown in fig. 9). In this detection operation, when detecting that the error information transmitted from the server 3 has been received, the remote monitoring unit 4 causes the display unit 22 to display the received error information (step ST 32). This allows the operator to perform an operation of eliminating an error occurring in work implement 2 while viewing the error information displayed on display unit 22.

After the error information is displayed on the display unit 22 in step ST32, the remote monitoring unit 4 enters a standby state for input (error correction operation input or task return input) by the operator (step ST 33). When the input by the operator is present, the remote monitoring unit 4 determines whether or not the input is an error correction operation input (step ST34), and when the input is determined to be an error correction operation input, transmits an operation signal (correction operation signal) corresponding to the error correction operation input to the server 3 (step ST35), and then returns to step ST 31. On the other hand, when determining in step ST34 that the input is not the error correction operation input (is the task return input), the remote monitoring unit 4 returns to step ST31 after transmitting the task return signal to the server 3 (step ST 36).

After transmitting the error information to the remote monitoring units 4 in step ST23 described above, or when the error information is not received in step ST21 described above, the server 3 determines whether or not a task return signal has been received from any of the plurality of remote monitoring units 4 (step ST24 of the flowchart of fig. 8). When receiving the task return signal 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 transmitted the task return signal are searched again. Then, the remote monitoring unit 4 detected in the search that is performed anew retransmits (transmits) the error information (step ST 23).

As described above, in the present embodiment, the operator of the remote monitoring unit 4 can perform the task return input of returning the task of the error correction operation to the server 3 from the remote monitoring unit 4 without performing the error correction operation for the error information transmitted from the server 3. When a task return input is made from the remote monitoring unit 4, the server 3 performs a search by the search unit 31b again for the remote monitoring units 4 other than the remote monitoring unit 4 that made the task return input. Therefore, the operator of the remote monitoring unit 4 can transfer a task that is considered to be difficult to handle by itself to another operator by performing the task return input, and can smoothly eliminate the error of the entire work line 2L.

After retransmitting the error information, the server 3 proceeds to step ST24 to determine whether or not a task return signal is received from another remote monitoring unit 4. When receiving the task return signal from another remote monitoring unit 4, the process proceeds to step ST22 again, and when not receiving the task return signal from another remote monitoring unit 4, it is determined whether or not the cancel operation signal has been received from any of the plurality of remote monitoring units 4 (step ST 25). When the cancel operation signal is received from any of the plurality of remote monitoring units 4, the cancel operation signal is transmitted to the work device 2 corresponding to the received cancel operation signal (step ST26), and the process returns to step ST 21. On the other hand, if the cancel operation signal is not received in step ST25, the process returns to step ST 21.

In step ST15 described above, if the error information is transmitted to the server 3, each of the working devices 2 waits for reception of the cancel operation signal transmitted from the server 3 (step ST16 of the flowchart of fig. 7). Then, if the cancel operation signal transmitted from the server 3 is received, a necessary process for canceling the error occurring in the job device 2 is executed in accordance with the received cancel operation signal (step ST 17). The working device 2 executes processing for canceling the error generated by itself based on the received cancel operation signal, and then exits from the remote operation mode (step ST 18). Then, the process returns to step ST11 to perform the detecting operation again to determine whether or not an error has occurred.

As described above, in the remote operation system 1 according to the present embodiment, the server 3 relays information on errors that have occurred in each of the plurality of work apparatuses 2 and transmits the relayed information to any of the plurality of remote monitoring units, and the server distributes information on a plurality of errors received from the plurality of work apparatuses 2 to the plurality of remote monitoring units 4 and transmits the distributed information. Therefore, a plurality of errors occurring in the plurality of work apparatuses 2 are distributed to the plurality of remote monitoring units 4, and a plurality of errors occurring at the same time are not concentrated on one operator as in the conventional case. As a result, the error correction processing is smoothly performed, and the tact of the entire line 2L cannot be slowed down. That is, according to the remote operation system 1 of the present embodiment, it is possible to eliminate a plurality of errors occurring at the same time as the plurality of work apparatuses 2 without delay.

The embodiments of the present disclosure have been described above, but the present invention is not limited to the above-described embodiments, and various modifications and the like can be made. For example, in the above-described embodiment, when a plurality of remote monitoring units 4 in a state that can be handled by an operator are detected by searching, the server 3 transmits error information to the remote monitoring unit 4 that has the longest elapsed time since the error removal operation for the previous error is performed, among the plurality of detected remote monitoring units 4. However, the error information may be assigned by applying a reference in consideration of the work capability of the operator (a reference in which the remote monitoring unit 4 operated by the operator having higher work capability transmits more tasks) instead of or in addition to such a reference.

In the above-described embodiment, the plurality of work apparatuses 2 constitute the work line 2L, but the work apparatus 2 to which the present invention is applied does not necessarily constitute the work line 2L. In the above-described embodiment, the working device 2 is a component mounting device in which the component BH is mounted on the substrate KB to be worked, but the working device 2 to which the present invention is applied is not limited to the component mounting device.

According to the present disclosure, it is possible to eliminate a plurality of errors occurring at the same time as a plurality of working devices without delay.
