It is shown. As shown in FIG. 1, the electronic component mounting line L has four mounting machines 10 (10a, 10b, 10c, 10d) for mounting the electronic component 4 on the circuit board 2. The work management device 8 and each mounting device 10 are communicably connected to each other. A plurality of workers are deployed in the electronic component mounting line L, and each worker carries out various work items for each mounting machine 10. The electronic component mounting line L usually has other board working machines such as a solder printing machine and a board inspection machine, but these are not shown in FIG. 1.

The mounting machine 10 will be described with reference to FIGS. 2 and 3. Each of the mounting machines 10a to 10d includes a plurality of component feeders 12, a feeder holding unit 14, a mounting head 16, a head moving device 18, an image pickup device 32, a substrate conveyor 20, and a control device 22. Further, the face recognition sensors 24 (24a to 24d), the monitors 26 (26a to 26d), the speakers 28 (28a to 28d), and the monitors 30 (30a to 30d) are installed on the mounting machines 10a to 10d, respectively. There is. The face recognition sensor 24, the monitor 26, the speaker 28, and the monitor 30 are members included in the work management device 8, but are installed in the wearing machine 10 in this embodiment. The face recognition sensor 24 corresponds to an example of the "worker detection unit", the monitor 26 and the speaker 28 correspond to an example of the "work instruction unit", and the monitor 30 corresponds to an example of the "display unit".

Each component feeder 12 accommodates a plurality of electronic components 4. The component feeder 12 is detachably attached to the feeder holding portion 14 and supplies the electronic component 4 to the mounting head 16. The specific configuration of the component feeder 12 is not particularly limited. Each component feeder 12 is, for example, a tape-type feeder that accommodates a plurality of electronic components 4 on a wound tape, a tray-type feeder that accommodates a plurality of electronic components 4 on a tray, or a plurality of electronic components 4 in a container. It may be any of the bulk type feeders that randomly accommodate the above.

The mounting head 16 has a nozzle 6 that attracts the electronic component 4. The mounting head 16 can move the nozzle 6 in the Z direction (here, the vertical direction). The mounting head 16 can attach the electronic component 4 from the component feeder 12 by the nozzle 6 and mount the electronic component 4 attracted to the nozzle 6 on the circuit board 2. The head moving device 18 moves the mounting head 16 and the fixing member 29 (described later) between the component feeder 12 and the circuit board 2. As an example, the head moving device 18 of this embodiment is an XY robot that moves the moving base 18a in the X direction and the Y direction, and the mounting head 16 is detachably attached to the moving base 18a.

The image pickup apparatus 32 is fixed to the moving base 18a by the fixing member 29, and moves integrally with the moving base 18a. The image pickup apparatus 32 takes an image of the electronic component 4 adsorbed on the nozzle 6. The image data of the image captured by the image pickup device 32 is transmitted to the control device 22. The board conveyor 20 is a device for carrying in, positioning, and carrying out the circuit board 2. As an example, the substrate conveyor 20 of this embodiment has a pair of belt conveyors and a support device (not shown) that supports the circuit board 2 from below.

The control device 22 is configured by using a computer including a CPU and a memory. The control device 22 controls the operation of each part of the mounting machine 10, for example, based on a production program. Further, the control device 22 detects the position and orientation of the electronic component 4 with respect to the nozzle 6 by performing image processing on the image captured by the image pickup device 32, and calculates the correction amount of the mounting position.
Further, the control device 22 detects that the work item performed by the operator on the mounting machine 10 has been completed. For example, when the worker replaces the nozzle 6 when the work item is "replacement of the nozzle 6", the control device 22 detects that the replacement of the nozzle 6 is completed. When the control device 22 detects the end of the work item, the mounting machine 10 transmits the end of the work item to the work management device 8.
Further, the control device 22 calculates the mounting record of the electronic component 4 on the circuit board 2. As an example, the control device 22 calculates the time until the electronic component 4 set in the component feeder 12 is cut (hereinafter, also referred to as the component cut time) for each component feeder 12. The component cut time is calculated from the number of electronic components 4 set in the component feeder 12 and the feed rate of the component feeder 12. The mounting machine 10 transmits the component cut time of each component feeder 12 to the work management device 8.

The face recognition sensor 24 is, for example, a CCD image sensor, and is set so that a predetermined range around the wearing machine 10 is the detection range. When the face recognition sensor 24 detects a worker located in this predetermined range, the face recognition sensor 24 captures the face of the worker and transmits the face image data to the work management device 8. The face recognition sensor 24 can capture not only the face of a stationary worker but also the face of a walking worker, for example.

The monitor 26 selects from among the work items that the worker can perform on the wearing machine 10 on which the face recognition sensor 24 is installed for the worker detected by the face recognition sensor 24. The work items that have been performed are displayed, while if there are no work items that can be performed, it is displayed that there are no work items to be performed (described later). The speaker 28 outputs the content displayed on the monitor 26 by voice (described later).

If the monitor 30 has a work item that the worker can perform on the wearing machine 10 of any of the mounting machines 10a to 10d for the worker detected by the face recognition sensor 24, the monitor 30 performs all the work items. Display (described later).

Next, the work management device 8 will be described with reference to FIG. The work management device 8 is configured by using a computer including a memory 40 and a CPU 42. Further, the work management device 8 includes a face recognition sensor 24, a monitor 26 and a speaker 28, and a monitor 30. In this embodiment, these members 24, 26, 28, and 30 are installed in the mounting machine 10 (see FIG. 2) and are communicably connected to the work management device 8.

The memory 40 is provided with a face image database 44 and a work item storage unit 46. As shown in FIG. 5, the face image database 44 stores the face image of the worker working on the electronic component mounting line L in association with the worker identification information O1 to O4 (hereinafter, the identification information On (hereinafter, identification information On (? A worker having n = 1 to 4) is referred to as a worker On). In the face image database 44, the identification information and the face image of the workers O1 to O4 working on the electronic component mounting line L are registered in advance. The worker identification information and the face image correspond to an example of "worker information", and the face image database 44 corresponds to an example of "worker information storage unit".

As shown in FIG. 6, the work item storage unit 46 stores a group of work items to be performed on the mounting machine 10. Each work item is associated with identification information and a face image of a worker in charge of carrying out the work item, and types (10a to 10d) of mounting machines 10 on which the work item is carried out. For example, the work item of item 1 is carried out by the worker O1 in the mounting machine 10a and by the worker O2 in the mounting machine 10b. Specifically, the work items include "removing the component feeder 12b (see FIG. 3) from the feeder holding section 14", "setting the component feeder 12c (see FIG. 3) in the feeder holding section 14", and "nozzle 6". "Replace" and so on. In this embodiment, these work items are represented as items 1, 2, ... For the sake of ease of explanation. The work item storage unit 46 may have a configuration in which only one of the worker's identification information and the face image is associated with each work item.

An arithmetic program is stored in the memory 40, and when the CPU 42 executes the arithmetic program, the CPU 42 functions as a face recognition processing unit 48, a work item extraction unit 50, an update unit 52, and a work item addition unit 54. The face image data captured by the face recognition sensor 24 installed in the wearing machine 10 is transmitted from the wearing machine 10 to the work management device 8. The face authentication processing unit 48 analyzes the face image data, collates the analyzed face image data with the face image of the face image database 44, and identifies the worker from the face image database 44.

The work item extraction unit 50 extracts work items in two stages. In the first stage, the work item extraction unit 50 selects the work item associated with the worker's identification information and the face image identified by the face authentication processing unit 48 from the work item group of the work item storage unit 46. Extract. The work management device 8 displays all the work items extracted in the first stage processing on the monitor 30 installed in the mounting machine 10. On the other hand, if there is no work item associated with the worker's identification information and the face image in the work item group of the work item storage unit 46, the work item extraction unit 50 does not extract the work item. In this case, the work management device 8 causes the monitor 30 to display that there is no work item to be performed.

In the second stage, the work item extraction unit 50 is associated with the work item 10 on which the face recognition camera 24 that captures the worker is installed from the work items extracted in the first stage process. Is further extracted. The work management device 8 displays the work item selected from the work items extracted in the second stage processing on the monitor 26 installed in the mounting machine 10, and announces it from the speaker 28. On the other hand, if there is no work item associated with the wearing machine 10 on which the face recognition camera 24 that captures the image of the worker is installed among the work items extracted in the first stage processing, the work item extraction unit 50 Does not extract work items. In this case, the work management device 8 causes the monitor 26 to display that there is no work item to be performed, and causes the speaker 28 to announce. Since the work item storage unit 46 stores each work item in association with the worker's identification information and the face image, the work item extraction unit 50 stores the work items that the worker can perform from the work item storage unit 46. It can be extracted accurately.

When the control device 22 of the mounting machine 10 detects the end of the work item, the mounting machine 10 transmits the end of the work item to the work management device 8. Then, in the update unit 52, the worker identification information and the face image identified by the face recognition processing unit 48 are stored in association with the work item in the work item storage unit 46 with the worker identification information and the face image. If they match, the work item group is deleted from the work item group of the work item storage unit 46, and the work item group is updated. On the other hand, if this is not the case, the update unit 52 does not update the work item group (that is, does not delete the work item from the work item group).

For example, consider a case where the work management device 8 receives the end of item 1 from the wearing machine 10a when the face recognition sensor 24a detects the worker O1. In this case, the identification information and the face image of the worker O1 identified by the face recognition processing unit 48 are stored in the work item storage unit 46 (see FIG. 6) in association with the item 1 and the wearing machine 10a. Matches identification information and facial image. Therefore, as shown in FIG. 7, the update unit 52 deletes the item 1 associated with the mounting machine 10a from the work item group. On the other hand, consider the case where the work management device 8 receives the end of item 1 from the mounting machine 10a when the face recognition sensor 24a detects the worker O2. In this case, the identification information and face image of the worker O2 identified by the face authentication processing unit 48 are stored in association with the item 1 and the wearing machine 10a in the work item storage unit 46, and the identification information and face image of the worker O1 are stored. Therefore, the update unit 52 does not delete the item 1 associated with the mounting machine 10a from the work item group.

As described above, the control device 22 calculates the component cut time of the electronic component 4 set in each component feeder 12. The mounting machine 10 transmits the result to the work management device 8. The work item addition unit 54 stores the required preparation time of each component feeder 12. The work item addition unit 54 compares the component cut time of each component feeder 12 transmitted from the mounting machine 10 with the required preparation time of the corresponding component feeder 12. When the part cut time becomes less than the required preparation time, the work item addition unit 54 adds a work item to the work item storage unit 46 to replace the part feeder 12 whose parts will soon be cut with a new part feeder 12. The work item addition unit 54 adds a work item to be added based on the table data associating the work item for which each part feeder 12 is replaced with the identification information and the face image of the worker who can carry out the work item. The identification information and the face image of the above are associated with the type of the wearing machine 10 and added to the work item storage unit 46.

The monitor 26 displays to the worker the work item selected from the work items extracted by the work item extraction unit 50 in the second stage processing. Therefore, only the work items associated with the mounting machine 10 on which the monitor 26 is installed are displayed on the monitor 26. The speaker 28 announces to the worker the same contents as the work items displayed by the monitor 26. The number of work items output by the monitor 26 and the speaker 28 is not limited to one item, and two or more items may be output. Further, when the work item extraction unit 50 does not extract the work item in the second stage processing, the monitor 26 displays that there is no work item to be executed, and the speaker 28 announces the same content (for example,). "There is no work that can be done" etc.).

The monitor 30 displays to the worker all the work items extracted by the work item extraction unit 50 in the first stage processing. Therefore, the monitor 30 is detected by the face recognition sensor 24 in the work item group of the work item storage unit 46 (that is, identified by the face recognition processing unit 48) regardless of the type of the wearing machines 10a to 10d. T) All the work items associated with the worker's identification information and facial image are displayed.

Next, the operation of the work management device 8 in the following cases 1 to 3 will be described with reference to the flowcharts of FIGS. 9 and 10. In the following, the work item storage unit 46 stores the work item group shown in FIG.

(Case 1: Worker O1 approaches the mounting machine 10a)
When the worker O1 approaches the wearing machine 10a and enters the detection range of the face recognition sensor 24a, the face recognition sensor 24a detects the worker O1 (YES in step S2) and images the face of the worker O1 (step). S4). The face image data of the face of the worker O1 is transmitted from the face recognition sensor 24a to the work management device 8. Next, the face recognition processing unit 48 of the work management device 8 identifies the worker O1 based on the face image database 44 (step S6). Subsequently, the work item extraction unit 50 of the work management device 8 associates the work item group stored in the work item storage unit 46 with the identification information and the face image of the worker O1 registered in the face image database 44. It is determined whether or not there is a work item that has been completed (step S8). In case 1, since the work item is included in the work item group (YES in step S8), the work item (that is, items 1 and 2 for the mounting machine 10a and item 1 for the mounting machine 10c) is extracted (that is, item 1 for the mounting machine 10c). Step S10).

Subsequently, the work item extraction unit 50 was associated with the wearing machine 10a (that is, the wearing machine on which the face recognition sensor 24a that detected the worker O1 is installed) from the work items extracted in step S10. It is determined whether or not there is a work item (step S14). In case 1, since the work item is included in the work items extracted in step S10 (YES in step S14), the work items (that is, items 1 and 2) are extracted (step S16). Subsequently, the work management device 8 causes the monitor 30a to display all the work items extracted in step S10 (step S20). For example, the work management device 8 causes the monitor 30a to display "item 1 for the mounting machine 10a, item 2 for the mounting machine 10a, and item 1 for the mounting machine 10c" in the form of a table. Subsequently, the work management device 8 causes the monitor 26a to display the work item selected from the work items extracted in step S16 (referred to as item 1 in this embodiment), and announces the item 1 from the speaker 28a. (Step S22). For example, the work management device 8 causes the speaker 28a to announce "Please carry out item 1".

The monitor 30a allows the operator O1 to confirm all the work items that he / she can perform on the electronic component mounting line L. Therefore, it can be seen that the worker O1 may move to the mounting machine 10c and perform the work of item 1 after performing the work of item 1 and item 2 on the mounting machine 10a. Therefore, the worker O1 does not have to manage what kind of work item should be carried out by which mounting machine 10 by himself / herself, and the burden on the worker O1 is reduced. Further, since the worker O1 can easily grasp the type of the mounting machine 10 capable of carrying out the work item, the worker O1 can move to the mounting machine 10 on which the work item should be carried out without waste, and the work efficiency is improved.
Further, the worker O1 is instructed by the monitor 26a and the speaker 28a about the work items that can be performed on the mounting machine 10a. The face recognition sensor 24a that detects the worker O1 is installed in the mounting machine 10a, and the monitor 26a and the speaker 28a are also installed in the mounting machine 10a. Therefore, when the worker O1 receives an instruction from the monitor 26a and the speaker 28a, the worker O1 can immediately start the work on the mounting machine 10a located in the vicinity of the monitor 26a and the speaker 28a, and the work efficiency can be improved.

When the step S22 is completed, the work management device 8 determines whether or not the end of the work item has been received from the mounting machine 10a after the lapse of a predetermined time (step S24). When the work management device 8 receives the end of item 1 from the mounting machine 10a (YES in step S24), the update unit 52 of the work management device 8 receives the identification information and the face image of the worker O1 identified by the face recognition processing unit 48. Determines whether or not the work item storage unit 46 matches the worker identification information and the face image stored in association with the item 1 (step S26). In case 1, since they match (YES in step S26), the update unit 52 updates the work item group by deleting the item 1 associated with the mounting machine 10a from the work item group of the work item storage unit 46. (See FIG. 7 (step S28)).

As a result, when the face recognition sensor 24a subsequently detects the worker O1, the monitor 30a has a work item in which the item 1 associated with the mounting machine 10a is deleted (that is, the item 2 for the mounting machine 10a and the mounting machine 10c). 1) is displayed, and item 2 is instructed from the monitor 26a and the speaker 28a. In this way, each time the work item is completed, the update unit 52 deletes the completed work item from the work item group of the work item storage unit 46, so that the work item storage unit 46 has the work item to be executed from now on and the work item to be executed. Only the work item currently being worked on will be stored. Therefore, the monitor 26a, the speaker 28a, and the monitor 30a do not instruct the worker O1 of the already completed work item (for example, item 1), and the work can proceed efficiently. Further, since it is not necessary for the worker himself / herself to delete the finished work item from the work item group list or the like, the work time can be shortened. When step S28 is completed, the process returns to step S2.

(Case 2: Worker O4 approaches the mounting machine 10a)
In case 2, the face recognition processing unit 48 identifies the worker O4 through the same procedure as in steps S2 to S6 of case 1 (steps S2 to S6). Next, the work item extraction unit 50 determines from the work item group stored in the work item storage unit 46 whether or not there is a work item associated with the identification information of the worker O4 and the face image (step S8). ). In case 2, there is no such work item in the work item group (NO in step S8). Therefore, the work management device 8 causes the monitor 30a to display that there is no work item to be performed, and also displays / announces from the monitor 26a and the speaker 28a (step S12). As a result, the worker O4 can know that there is no work item that can be carried out for the mounting machines 10a to 10d. Therefore, the worker O4 can perform work other than the work item (for example, preparatory work for setup change which is not stored in the work item storage unit 46), and the work can proceed smoothly.

When step S12 is completed, the work management device 8 determines whether or not it has received from the mounting machine 10a that the work item has been completed after a predetermined time has elapsed (step S24). When the worker O4 has not performed the work item on the mounting machine 10a, the work management device 8 does not receive from the mounting machine 10a that the work item has been completed even after the predetermined time has elapsed (step). NO in S24), the process returns to step S2. On the other hand, when the worker O4 performs a work item (for example, item 1) on the mounting machine 10a, the work management device 8 receives the end of the item 1 from the mounting machine 10a after a predetermined time has elapsed (step). YES in S24). In this case, the identification information and face image of the worker O4 identified by the face recognition processing unit 48 do not match the identification information and face image of the worker O1 stored in association with the item 1 in the work item storage unit 46. (NO in step S26), the update unit 52 does not update the work item group of the work item storage unit 46 (step S30), and returns to step S2. According to this configuration, even if a worker other than the worker in charge of carrying out the work item carries out the work item, the work is invalid. Therefore, it is possible to ensure that the work item is carried out by the worker in charge of carrying out the work item.

(Case 3: Worker O2 approaches the mounting machine 10a)
In case 3, the face recognition processing unit 48 identifies the worker O2 through the same procedure as in steps S2 to S6 of case 1 (steps S2 to S6). Next, the work item extraction unit 50 determines from the work item group stored in the work item storage unit 46 whether or not there is a work item associated with the identification information of the worker O2 and the face image (step S8). ). In Case 3, since the work item is included in the work item group (YES in step S8), the work item (that is, items 1 and 3 for the mounting machine 10b) is extracted (step S10). Subsequently, the work item extraction unit 50 determines whether or not there is a work item associated with the mounting machine 10a from the work items extracted in step S10 (step S14). In case 3, the work item extracted in step S10 does not have the work item (NO in step S14). Therefore, the work management device 8 causes the monitor 30a to display "item 1 for the mounting machine 10b, item 3 for the mounting machine 10b", and causes the monitor 26a and the speaker 28a to perform the work to be performed on the mounting machine 10a. Display / announce that there is no item (step S18). As a result, the worker O2 can know that there is no work item that can be carried out for the mounting machine 10a, but there is a work item that can be carried out for the mounting machine 10b. Therefore, the worker O2 can move to the mounting machine 10b to perform the work.

According to this configuration, the worker can be appropriately guided to the mounting machine 10 having a work item that the worker can carry out. Therefore, the worker does not hesitate which mounting machine 10 should be used for work, and the work efficiency is improved. Further, according to this configuration, the worker O2 can clearly know that there is no work item to be carried out for the mounting machine 10a. This is particularly remarkable when the mounting machine 10a does not have a monitor 30a for displaying all work items. That is, when there is no monitor 30a and the monitor 26a and the speaker 28a do not output that there is no work item, the operator suspects that the face recognition sensor 24a has a detection error or a malfunction, and the wearing machine 10a. I can't be sure if there really aren't any work items that can be done. However, according to the above configuration, since the monitor 26a and the speaker 28a clearly / clearly indicate that there is no work item, the operator can move to another mounting machine 10 with confidence.

When step S18 is completed, the work management device 8 operates in the same procedure as steps S24 to S30 of the case 2 (steps S24 to S30). Specifically, when the worker O2 performs a work item (for example, item 1) on the mounting machine 10a, the identification information and the face image of the worker O2 identified by the face recognition processing unit 48 are the work items. Since the identification information and the face image of the worker O1 stored in association with the item 1 in the storage unit 46 do not match (NO in step S26), the update unit 52 updates the work item group of the work item storage unit 46. (Step S30), the process returns to step S2. This configuration also makes it possible to ensure that the work item is carried out by the worker in charge of carrying out the work item.

Next, the operation of the work item addition unit 54 of the work management device 8 will be described with reference to the flowchart of FIG. As described above, the work item addition unit 54 adds the work item to the work item storage unit 46 based on the table data. The table data stores the work item for replacing the component feeder 12a (see FIG. 3) of the mounting machine 10a in association with the identification information and the face image of the worker O1. Further, in the following, the work item storage unit 46 stores the work item group shown in FIG. 7.

The work management device 8 determines whether or not the component cut time of each component feeder 12 has been received from the mounting machine 10 (step S40). If the work management device 8 does not receive the parts out time (NO in step S40), the process returns to step S40. On the other hand, when the work management device 8 receives the part cut time (YES in step S40), the work item addition unit 54 of the work management device 8 requires the part cut time of each part feeder 12 to be required by each part feeder 12. It is determined whether or not it is less than or equal to the preparation time (step S42). If the component cut time of each component feeder 12 is longer than the required preparation time of each component feeder 12 (NO in step S42), the process returns to step S40. On the other hand, for example, when the part cut time of the part feeder 12a is less than or equal to the required preparation time (for example, 3 minutes) of the part feeder 12a (YES in step S42), the work item addition unit 54 has the work item addition unit 54 as shown in FIG. A work item for replacing the component feeder 12a (in FIG. 8, the work item is referred to as item 4) is added to the work item storage unit 46 in association with the identification information and face image of the worker O1 and the mounting machine 10a (in FIG. 8). Step S44).

According to this configuration, when the worker O1 is located near the mounting machine 10a (strictly speaking, when it is located within the detection range of the face recognition sensor 24a), the component feeder 12a is replaced with the monitor 26a. The work item is displayed, and the same content is announced from the speaker 28a. As a result, the worker O1 can preferentially carry out the work item. On the other hand, when the worker O1 is located in the vicinity of a mounting machine other than the mounting machine 10a (for example, the mounting machine 10b), a work item for replacing the component feeder 12a is displayed on the monitor 30b. At this time, the work item may be blinked and displayed so that the worker O1 can easily notice the addition of the work item. As a result, the worker O1 can move to the mounting machine 10a and perform the replacement work of the component feeder 12a.

In this way, by calculating the parts out time and preparing for replacement of the parts feeder 12 in advance, the work can proceed smoothly without delay. At this time, the work item addition unit 54 may add the part cut time to the content of the work item (“replace the part feeder 12a within 3 minutes”, etc.). The work item added by the work item addition unit 54 is not limited to the replacement work of the component feeder 12, and any work item required during the operation of the mounting machine 10 may be configured to be able to be added.

In the work management device 8 of the first embodiment, when the face recognition sensor 24 detects the worker, the monitor 26 and the speaker 28 indicate the work items that the worker can perform to the wearing machine 10. Therefore, the worker may work according to the instructions of the monitor 26 and the speaker 28, and the worker himself does not need to grasp the work flow or manage the progress state of the work. Therefore, it is possible to reduce the burden on the operator while maintaining the work accuracy.

The work management device 108 of the second embodiment will be described with reference to FIGS. 12 to 18. Hereinafter, the differences from the first embodiment will be described, the same components as those in the first embodiment will be designated by the same reference numerals, and detailed description thereof will be omitted. In the second embodiment, the configurations of the work item storage unit 146 and the face image database 144 are different from those in the first embodiment. Specifically, each work item is ranked according to the difficulty levels A, B, and C of the work item. As shown in FIG. 13, in the work item storage unit 146, each work item is stored in association with the difficulty levels A to C of the work item and the type of the mounting machine 10 on which the work item is carried out. For example, item 13 implemented for the mounting machine 10a is associated with difficulty level A. The difficulty increases from difficulty C to A. Further, as shown in FIG. 12, in the face image database 144, the difficulty levels A to C of the work items that can be performed by the workers O1 to O4 are the worker identification information (O1 to O4) and the face image. It is remembered in association with. For example, the worker O1 is ranked with a difficulty level B, which means that the worker O1 can perform a work item having a difficulty level B or lower. That is, the worker O1 can carry out not only the work item of the difficulty level B but also the work item of the difficulty level C.

FIG. 14 shows the work management device 108 and the electronic component mounting line L2 of this embodiment. As shown in FIG. 14, on the electronic component mounting line L2, the workers O1 to O4 are located in a range that can be detected by the face recognition sensors 24a to 24d, respectively. The worker O1 carries out the work of item 12 (see FIG. 13) for the mounting machine 10a. As shown in FIG. 15, in addition to the configuration of the work management device 8 of the first embodiment, the work management device 108 of the present embodiment includes an environment map storage unit 156, a support request input unit 158 (158a to 158d), and the support request input unit 158 (158a to 158d). A suitable person selection unit 160 is provided. The environment map storage unit 156 is provided in the memory 40. As shown in FIG. 16, the environment map storage unit 156 stores the environment map 157 in which the position information of the wearing devices 10a to 10d and the face recognition sensors 24a to 24d is recorded. The support request input units 158a to 158d are installed in the mounting machines 10a to 10d, respectively. The support request input unit 158 can input that the worker needs support when the worker working on the mounting machine 10 needs support. When the support request is input to the support request input unit 158, the work management device 108 receives the input of the support request. The suitable person selection unit 160 selects the most suitable worker for the support request from the workers located in the range where the face recognition sensor 24 can detect in the electronic component mounting line L2.

Next, the operation of the work management device 108 in the following cases 4 to 6 will be described with reference to the flowcharts of FIGS. 17 and 18. In the following, the work item storage unit 146 stores the work item group shown in FIG.

(Case 4: Worker O1 approaches the mounting machine 10a)
First, when the face authentication sensor 24a detects the worker O1 (YES in step S52) and images the face of the worker O1 (step S54), the face recognition processing unit 48 moves the worker based on the face image database 144. Identify O1 (step S56). Next, the work item extraction unit 150 associates the work item group stored in the work item storage unit 46 with a difficulty level equal to or lower than the difficulty level (that is, difficulty level B) ranked by the worker O1. It is determined whether or not there is a work item that has been completed (step S58). In case 4, since there is the work item (YES in step S58), the work item extraction unit 150 has items 11 and 12 for the mounting machine 10a, items 11 for the mounting machine 10b, and the mounting machine 10c as the work items. Item 11 is extracted (step S60). Subsequently, the work item extraction unit 150 determines whether or not there is a work item associated with the mounting machine 10a from the work items extracted in step S60 (step S64). In case 4, since there is a work item associated with the mounting machine 10a among the work items extracted in step S60 (YES in step S64), the work item (that is, items 11 and 12) is extracted (that is, items 11 and 12). Step S66).

Subsequently, the work management device 108 causes the monitor 30a to display all the work items extracted in step S60 (step S70), and causes the monitor 26a and the speaker 28a to select from the work items extracted in step S66. The work item (for example, item 12) is displayed / announced (step S72). When the step S72 is completed, the work management device 108 determines whether or not the support request has been input to the support request input unit 158 (step S74). If the work management device 108 does not receive the input of the support request (NO in step S74), the process proceeds to step S84. On the other hand, when the support request is input to the support request input unit 158a, the work management device 108 receives the input of the support request (YES in step S74). Subsequently, the work management device 108 determines whether the difficulty level ranked for the worker who has input the support request is equal to or higher than the difficulty level of the work item requiring support (step S76). In case 4, since the difficulty level B of the worker O1 matches the difficulty level B of the item 12 (YES in step S76), the process proceeds to step S78. On the other hand, when the difficulty level of the worker is less than the difficulty level of the work item requiring support (NO in step S76), the process proceeds to step S84.

Since the face image data of the worker detected by the face recognition sensor 24 of each wearing machine 10 is intermittently transmitted to the face recognition processing unit 48, the face recognition processing unit 48 is in the vicinity of each wearing machine 10. Workers O1 to O4 are identified in advance. Based on the face image database 144, the suitable person selection unit 160 of the work management device 108 has difficulty level B or higher of item 12 requiring support among the remaining workers O2 to O4 excluding the worker O1 who requested support. Workers O3 and O4 ranked according to the difficulty level of are selected (step S78 (see FIG. 12)). Next, the suitable person selection unit 160 performs face recognition closer to the wearing machine 10a on which the worker O1 is working among the face recognition sensors 24c and 24d that have detected the workers O3 and O4, respectively, based on the environment map 157. The worker O3 detected by the sensor 24c is selected as the most suitable worker for the support request (step S80). Subsequently, the work management device 108 causes the monitor 26c and the speaker 28c of the mounting machine 10c to display / announce to the worker O3 that he / she is going to support the mounting machine 10a (step S82). According to this configuration, when a worker requests support, it is possible to quickly detect the most suitable worker for support and instruct to go to support. Therefore, it is possible to suppress the work from being stagnant, and the work efficiency is improved.

When the step S82 is completed, the work management device 108 determines whether or not the end of the work item has been received from the mounting machine 10a after the lapse of a predetermined time (step S84). When the work management device 108 receives the end of the item 12 (YES in step S84), the update unit 152 has a difficulty level of the work item storage unit 46, which is ranked as the worker O1 identified by the face authentication processing unit 48. In (step S86), it is determined whether or not the difficulty level is higher than the difficulty level stored in association with the item 12. In case 4, since the difficulty levels of both are the same (YES in step S86), the update unit 152 updates the work item group (step S88). When the end of step S88 is completed and the end of the work item is not received even after the lapse of a predetermined time (NO in step S84), the process returns to step S52.

According to the above configuration, since the worker's identification information or the face image is not stored in the work item storage unit 146, the workers ranked at the same level of difficulty carry out the same work item. It becomes possible. Therefore, even if a certain worker cannot continue the work, the worker who is ranked in the same or higher difficulty level as the worker performs the work instead, and the work item storage unit 146 You don't have to rewrite the information. Therefore, it is possible to efficiently proceed with the work while preventing a decrease in work accuracy. Further, in the above configuration, the worker can perform the work item associated with the difficulty level equal to or lower than the difficulty level ranked for the worker. Therefore, the degree of freedom of work items that can be carried out by each worker can be increased, and even if a worker is vacant, it is possible to flexibly respond.

(Case 5: After carrying out item 11 for the mounting machine 10a and item 11 for the mounting machine 10b, the worker O2 approaches the mounting machine 10a)
In case 5, the face recognition processing unit 48 identifies the worker O2 through the same procedure as in steps S52 to S56 of case 4 (steps S52 to S56). Next, the work item extraction unit 150 associates the work item group stored in the work item storage unit 146 with a difficulty level of the difficulty level (that is, difficulty level C) or less ranked by the worker O2. It is determined whether or not there is a work item that has been completed (step S58). In case 5, the item 11 for the mounting machine 10a and the item 11 for the mounting machine 10b are completed, and the updating unit 152 deletes and updates the two items from the work item storage unit 146 shown in FIG. Therefore, there is no work item satisfying the above conditions in the work item group (NO in step S58). Therefore, the work management device 108 causes the monitor 30a to display that there is no work item to be performed, and also displays / announces from the monitor 26a and the speaker 28a (step S62).

When the step S62 is completed, the work management device 108 determines whether or not the support request has been input to the support request input unit 158 (step S74). If the work management device 108 does not receive the input of the support request (NO in step S74), the process proceeds to step S84. On the other hand, if the worker O2 implements item 12 (difficulty level B) for the mounting machine 10a and inputs a support request to the support request input unit 158a during the implementation (YES in step S74), the work management device 108 determines whether the difficulty level C ranked in the worker O2 for which the support request is input is equal to or higher than the difficulty level of the item 12 which is a work item requiring support (step S76). In case 5, the difficulty level C of the worker O2 is less than the difficulty level B of the item 12 (NO in step S76), so that the work management device 108 determines that the support request is inappropriate and gives an instruction for support. Instead, the process proceeds to step S84.

The work management device 108 determines whether or not it has received from the mounting machine 10a that the work item has been completed after the lapse of a predetermined time (step S84). If the worker O2 has not performed the work item on the mounting machine 10a, the work management device 108 does not receive from the mounting machine 10a that the work item has been completed even after the predetermined time has elapsed (step). NO in S84), the process returns to step S52. On the other hand, when the worker O2 performs a work item (for example, item 12) on the mounting machine 10a, the work management device 108 receives the end of the item 12 from the mounting machine 10a after a predetermined time has elapsed (step). YES in S84). In this case, it is determined whether or not the difficulty level ranked in the worker O2 identified by the face recognition processing unit 48 is equal to or higher than the difficulty level stored in association with the item 12 in the work item storage unit 46 (). Step S86). In case 5, the difficulty level C ranked in the worker O2 is less than the difficulty level B associated with the item 12 (NO in step S86), so that the update unit 152 does not update the work item group. (Step S90), the process returns to step S52. This configuration also makes it possible to ensure that the work item is carried out by the worker in charge of carrying out the work item.

(Case 6: Worker O2 approaches the mounting machine 10c)
In case 6, the face recognition processing unit 48 identifies the worker O2 through the same procedure as in steps S52 to S58 of case 4 (steps S52 to S58). In case 6, in the work item group stored in the work item storage unit 46, there is a work item associated with a difficulty level of difficulty level (that is, difficulty level C) or less ranked by the worker O2. (YES in step S58). Therefore, the work item extraction unit 150 extracts the work item (that is, the item 11 for the mounting machine 10a and the item 11 for the mounting machine 10b) (step S60). Subsequently, the work item extraction unit 150 determines whether or not there is a work item associated with the mounting machine 10a from the work items extracted in step S60 (step S64). In case 6, since there is no such work item (NO in step S64), the work management device 108 causes the monitor 30a to display "item 11 for the mounting machine 10a, item 11 for the mounting machine 10b", and also displays the monitor 26a and the monitor 26a. The speaker 28a displays / announces that there is no work item to be performed on the mounting machine 10a (step S68). As a result, the worker O2 can know that there is no work item that can be carried out for the mounting machine 10c, but there is a work item that can be carried out for the mounting machines 10a and 10b. Therefore, the worker O2 can move to the mounting machine 10a or 10b to perform the work.

When the step S68 is completed, the work management device 108 determines whether or not the support request has been input to the support request input unit 158 (step S74). If the work management device 108 does not receive the input of the support request (NO in step S74), the process proceeds to step S84. On the other hand, if the worker O2 implements item 11 (difficulty level B) for the mounting machine 10c and inputs a support request to the support request input unit 158c during the implementation (YES in step S74), the work management device 108 determines whether the difficulty level C ranked in the worker O2 for which the support request is input is equal to or higher than the difficulty level of the item 11 which is a work item requiring support (step S76). In case 6, since the difficulty level C of the worker O2 is less than the difficulty level B of the item 11 (NO in step S76), the work management device 108 determines that the support request is inappropriate and gives an instruction for support. Instead, the process proceeds to step S84.

The work management device 8 operates in the same procedure as in steps S84 to S90 of the case 5 (steps S84 to S90). Specifically, when the worker O2 performs the item 11 on the wearing machine 10c, the difficulty level C ranked in the worker O2 identified by the face recognition processing unit 48 is the work item storage unit 46. Since the difficulty level is less than the difficulty level B stored in association with the item 11 of the mounting machine 10c (NO in step S86), the update unit 152 does not update the work item group (step S90), and returns to step S52. This configuration also makes it possible to ensure that the work item is carried out by the worker in charge of carrying out the work item.

The examples of the techniques disclosed in the present specification have been described in detail above, but these are merely examples, and the semiconductor devices disclosed in the present specification include various modifications and modifications of the above examples. Is done.

For example, one face recognition sensor 24 is installed in each mounting machine 10, but the present invention is not limited to this configuration, and one face recognition sensor 24 may be placed in each of two adjacent mounting machines 10. In this case, it is preferable that the detection range of the face recognition sensor 24 extends to the vicinity of two adjacent mounting machines 10. Further, instead of the face recognition sensor 24, an RF tag may be used, or biometric authentication such as fingerprint authentication or iris authentication may be used. Further, the monitor 26, the speaker 28, and the monitor 30 may not be installed in the mounting machine 10, and may be arranged in the vicinity of the mounting machine 10, for example. Further, only one monitor 30 may be installed on the electronic component mounting line.
