Generally, the board working apparatus is provided with an operation unit for changing various set values, and an operator can operate the operation unit to change the set value (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2019-197823

If the operator makes an inappropriate change operation in the above-mentioned operation unit, the quality of the work may be deteriorated due to the change operation. Deterioration of work quality means, for example, that some trouble occurs due to the change operation, the success rate of work decreases, and the like.
However, conventionally, it has not been sufficiently examined to prevent the quality of work from being deteriorated by the change operation performed by the operator.

This specification discloses a technique for suppressing deterioration of work quality due to a change operation performed by an operator.

(1) According to one aspect of the present invention, the operation log management method for managing the operation log of the change operation for changing the operation of the board work apparatus for performing the work on the board includes the acquisition process for acquiring the operation log and the said operation log management method. The quality of the work deteriorates due to the change operation indicated by the operation log in the storage step of storing the operation log acquired in the acquisition step in the storage unit and the operation log stored in the storage unit. In the addition step of adding quality information indicating whether or not the work has been performed, and the change operation indicated by the operation log newly acquired in the acquisition step, the quality of the work may be deteriorated. The present invention includes a determination step of determining whether or not there is a presence or absence based on the other operation logs stored in the storage unit.

The above "change" means to change an already set value to a different value. In addition, "change" may be both setting a value for the first time in a state where nothing is set and changing an already set value to a different value.

According to the above operation log management method, it is determined based on other operation logs whether or not the change operation indicated by the newly acquired operation log is a change operation that may deteriorate the quality of work. do. Therefore, if it is determined that the change operation may deteriorate the quality of the work, the operator redoes the change operation so as to reduce the possibility of the quality of the work being deteriorated, so that the quality of the work is improved. It is possible to suppress the decrease.
Therefore, according to the above-mentioned operation log management method, it is possible to prevent the quality of work from being deteriorated due to the change operation performed by the operator.

(2) According to one aspect of the present invention, when it is determined in the determination step that the change operation may deteriorate the quality of the work, the operator performing the change operation is informed of the work. It may include a first notifying step of notifying that it is the change operation which may deteriorate the quality of the above.

According to the above operation log management method, if it is determined that the change operation may deteriorate the quality of the work, the operator performing the change operation may deteriorate the quality of the work. Since the notification is made, the notified operator can suppress the deterioration of the work quality by re-doing the change operation so as to reduce the possibility that the quality of the work is deteriorated.

(3) According to one aspect of the present invention, in the determination step, the quality information indicating that the quality of the work has deteriorated is added to the change operation indicated by the newly acquired operation log. If it is similar to the change operation indicated by the other operation log, it may be determined that the change operation may deteriorate the quality of the work.

If a change operation similar to the change operation indicated by the operation log to which quality information indicating that the quality of the work has deteriorated is performed, the quality of the work is likely to deteriorate due to the change operation.
According to the above operation log management method, the work is performed by determining whether or not the change operation is similar to the change operation indicated by the operation log to which the quality information indicating that the quality of the work has deteriorated is added. You can determine if this is a change operation that may degrade quality.

(4) According to one aspect of the present invention, in the determination step, the quality information indicating that the quality of the work has deteriorated is added to the change operation indicated by the newly acquired operation log. The same as the change operation indicated by the other operation log, or by the changed setting value of the change operation indicated by the newly acquired operation log and the other operation log. When the absolute value of the difference from the set value after the change of the change operation shown is equal to or less than a predetermined value, it may be determined that the change operation is similar to the change operation shown by the other operation logs.

The same change operation as the change operation indicated by the operation log to which quality information indicating that the work quality has deteriorated, or the absolute value of the difference from the changed setting value of the change operation indicated by the operation log. If is less than or equal to a predetermined value, the quality of work is likely to deteriorate.
According to the above operation log management method, the change operation indicated by the newly acquired operation log is the same as the change operation indicated by other operation logs to which quality information indicating that the quality of the work has deteriorated is added. Indicated by other operation logs by determining whether or not, or whether or not the absolute value of the difference between the changed operation and the changed set value indicated by the other operation log is less than or equal to the predetermined value. It is possible to determine whether or not the change operation is similar to the change operation.

(5) According to one aspect of the present invention, the quality information is information indicating whether or not a trouble has occurred in the work due to the change operation, and indicates that the quality of the work has deteriorated. The quality information may be the quality information indicating that the trouble has occurred.

According to the above operation log management method, it is possible to suppress the occurrence of troubles due to the change operation.

(6) According to one aspect of the present invention, in the determination step, the quality information indicating that the quality of the work is improved by the change operation indicated by the newly acquired operation log is added. If it conflicts with the change operation indicated by the other operation log, it may be determined that the change operation may deteriorate the quality of the work.

If a change operation that contradicts the change operation indicated by the operation log to which quality information indicating that the quality of the work has been improved is performed, the quality of the work is likely to deteriorate due to the change operation.
According to the above operation log management method, the work is performed by determining whether or not the change operation conflicts with the change operation indicated by the operation log to which the quality information indicating that the work quality has been improved is added. You can determine if this is a change operation that may degrade quality.

(7) According to one aspect of the present invention, the quality information is a change indicating the success rate of the work before the operation is changed and the success rate of the work after the operation is changed. The post-success rate is information indicating that the quality of the work has been improved, and the quality information may be the quality information in which the post-change success rate is higher than the pre-change success rate.

According to the above operation log management method, it can be determined whether or not the quality information indicates that the work quality has been improved.

(8) According to one aspect of the present invention, the contradictory change operation is a setting before the change of the other change operation in which the quality of the work is improved by increasing the set value as compared with the setting value before the change. The change operation to change to a setting value smaller than the value, and the setting value larger than the setting value before the change of the other change operation in which the quality of the work is improved by making the setting value smaller than before the change. It may be at least one of the above-mentioned change operations to be changed.

When the work quality is improved by making it larger than the setting value before the change, it can be said that making it smaller than the setting value before the change is a change operation contrary to the change operation in which the work quality is improved. On the contrary, when the work quality is improved by making it smaller than the setting value before the change, making it larger than the setting value before the change is a change operation contrary to the change operation in which the work quality is improved. I can say.

(9) According to one aspect of the present invention, the change operation is an operation of switching between valid and invalid of the function provided in the board work apparatus, and the contradictory change operation is the other change operation. It may be the change operation that invalidates the function when the quality of the work is improved by enabling the function.

When the quality of work is improved by enabling the function provided in the board work apparatus, disabling the function can be said to be a change operation contrary to the change operation in which the quality of work is improved.

(10) According to one aspect of the present invention, the change operation indicated by the newly acquired operation log is added with the quality information indicating that the quality of the work has been improved. If the change operation is similar to the change operation indicated by the operation log and the changed success rate of the other operation log is less than the reference value, the success rate of the work is given to the operator performing the change operation. May include a second notification step for notifying that the reference value may not be met.

A change operation similar to a change operation with an improved work success rate may improve the work success rate. However, even if the success rate of the work is improved, if the success rate after the change is less than the standard value, sufficient improvement in quality cannot be expected.
According to the above operation log management method, if the modified success rate of the modified operation shown by other similar operation logs does not meet the reference value, the operation success rate of the modified operation performed by the operator meets the reference value. Since the operator is notified that there is no possibility, the success rate of the work is more likely to reach the reference value when the operator redoes the change operation.

(11) According to one aspect of the present invention, the change operation is performed ex post facto by displaying the change operation indicated by the plurality of operation logs stored in the storage unit on the display unit in chronological order. It may include a regeneration step of regeneration.

Conventionally, the operation log of a change operation is stored, and when a trouble caused by the change operation occurs, the operation log is analyzed to identify the cause. However, in the past, since the stored operation log was analyzed as it was, it took time to identify the cause. Further, in order to analyze the operation log, it is necessary to understand the data format of the operation log, and if the data format is not understood, it takes more time.
According to the above operation log management method, the change operation is reproduced by displaying the change operation indicated by the operation log on the display unit, so the change operation that caused the trouble can be performed compared to the case where the operation log is analyzed as it is. It will be easier to identify.

(12) According to one aspect of the present invention, each time the operation log is acquired in the acquisition step, the change operation indicated by the acquired operation log is displayed on the display unit, whereby the change operation is performed. May include a reproduction step of reproducing in real time.

According to the above playback method, the change operation is played back in real time, so that the observer who monitors the change operation by the operator monitors the played change operation in real time and determines that the change operation deteriorates the quality of work. If this is the case, the possibility that the quality of work will deteriorate can be reduced by notifying the operator to that effect.

The invention disclosed herein can be realized in various aspects such as devices, methods, computer programs for realizing the functions of these devices or methods, recording media on which the computer programs are recorded, and the like.

It is possible to prevent the quality of work from being deteriorated by the change operation performed by the operator.

(4) Operation screen With reference to FIG. 6, an operation screen for changing the operation of each facility will be described. As described above, the operation of each facility can be changed by the operation unit provided in each facility or by the change support device 4. The screen transition of the operation screen is partially different between the case where the change is made by the operation unit provided in each facility and the case where the change is made by the change support device 4. Here, a case where a change is made by the change support device 4 will be described as an example.

When the operator activates the operation change program on the change support device 4, the equipment selection screen 60 is displayed. The equipment selection screen 60 is a screen that accepts the selection of the production line 2 and the selection of the equipment whose operation is to be changed from the equipment constituting the selected production line 2. In the following description, it is assumed that the surface mounter 14 is selected as the equipment.
When making a change in the operation unit provided in each equipment, the equipment selection screen 60 is not displayed and the menu screen 61 is displayed. When a change is made in the operation unit provided in each equipment, the equipment and the production line 2 to which the equipment belongs are automatically selected.

When the operator selects equipment on the equipment selection screen 60, the menu screen 61 is displayed. When the surface mounter 14 is selected as the equipment, menu items such as component information setting, feeder deceleration setting, and equipment setting are displayed on the menu screen 61. The menu items displayed on the menu screen 61 differ depending on the type of equipment selected.

When the operator selects the component information setting on the menu screen 61, the component selection screen 62 that accepts the selection of the type of component E is displayed. When the operator selects the type of component E on the component selection screen 62, the component information setting screen 63 is displayed. The component information setting screen 63 is a screen for changing various information related to the selected component E.
Specifically, in the example shown in FIG. 6, the nozzle descending deceleration rate, the nozzle ascending / decelerating rate, the nozzle descending amount, and the like are changed. The nozzle descent deceleration rate is a setting item in which the percentage of the standard descent speed to be slowed down when the suction nozzle 28B is lowered to suck the selected component E is set. The nozzle ascending / decelerating rate is a setting item for which the percentage of the standard ascending speed to be slowed down when the suction nozzle 28B is increased after the component E is adsorbed is set. The nozzle lowering amount is a setting item in which the amount of lowering the suction nozzle 28B when sucking the component E is set. For example, when the nozzle lowering amount is small, suction may fail due to a gap between the tip of the suction nozzle 28B and the component E. On the contrary, if the nozzle lowering amount is large, the suction nozzle 28B pushes the component E, which easily leads to the damage of the component.

When the operator selects the feeder deceleration setting on the menu screen 61, the feeder deceleration setting screen 64 is displayed. The feeder deceleration setting screen 64 changes the deceleration rate indicating what percentage of the standard delivery speed is slowed down when the component tape is fed by the feeder 23 for each set position in which the feeder 23 is set. It is a screen for.

When the operator selects the equipment setting on the menu screen 61, the equipment setting screen 65 is displayed. The surface mounter 14 has a function (erroneous mounting prevention function) of preventing the wrong component E from being mounted on the substrate P when the wrong component tape is set in the tape component supply device 22. .. On the equipment setting screen 65 of the surface mounter 14, the enable / disable of the erroneous mounting prevention function can be changed.
Although omitted in FIG. 6, various buttons such as an end button are also displayed on each operation screen.

(5) Operation log The operation log will be described with reference to FIGS. 7 to 10. The surface mounter 14 or the change support device 4 transfers the operation log of the operation to the operation log management device 3 every time the operation screens such as the component information setting screen 63, the feeder deceleration setting screen 64, and the equipment setting screen 65 are operated. Send. The operation log management device 3 acquires the operation log by receiving the operation log transmitted from the surface mounter 14 or the change support device 4 (an example of the acquisition process).

The operation log includes a transition log, which is a screen transition log, and an operation log, which is a log of operations performed on each screen. In the storage unit 52 of the operation log management device 3, a transition system table (see FIG. 7), which is a data table in which the transition system log is registered, and an operation system table (FIG. 8), which is a data table in which the operation system log is registered, are stored. See) and is remembered. Registering the operation log in these tables is an example of a storage process in which the operation log is stored in the storage unit 52.

The transition system table will be described with reference to FIG. 7. The transition system table has an operation ID, a screen ID, a time (start time, end time), a production line number, and an equipment number as data items.

The operation ID is given each time each operation screen is displayed. For example, when the component information setting screen 63 is displayed, a unique operation ID is assigned to the display of the component information setting screen 63. If the operator makes a change on the part information setting screen 63, closes the part information setting screen 63, and then displays the part information setting screen 63 again, another operation is performed for the newly displayed part information setting screen 63. An ID is given.

The screen ID is a data item in which the screen ID assigned to the displayed operation screen is registered. The screen ID is a character code consisting of numbers, alphabets, and the like, but in order to facilitate understanding, the screen name is shown as the screen ID as it is in FIG. 7.
The time is a data item in which the time when the operation screen is displayed (start time) and the time when the operation screen is closed (end time) are registered.

As the production line number, the number assigned to the production line 2 selected on the equipment selection screen 60 (or the number of the production line 2 to which the equipment belongs if the operation unit provided in the equipment has changed) is registered. It is a data item.
The equipment number is a data item in which the equipment number of the equipment selected on the equipment selection screen 60 (the equipment number of the equipment when the operation unit provided in the equipment is changed) is registered.

The operation system table will be described with reference to FIGS. 8 to 10. An operation table is provided for each operation screen. The operation system table shown in FIG. 8 is an operation system table of the component information setting screen 63. The operation table of the component information setting screen 63 has an operation ID, a component ID, a setting item ID, a set value (before change), a set value (after change), and a trouble flag (an example of quality information) as data items. There is.

The component ID of the component E selected on the component selection screen 62 described above is registered in the component ID.
The operation ID is the same as the operation ID described above. For example, when the component information setting screen 63 is displayed and the set value is changed, the same operation ID as the operation ID assigned to the component information setting screen 63 displayed at that time is registered in the operation ID. As a result, the operation screen and the operation are associated with each other.

The setting item ID is an ID assigned to the setting item whose set value has been changed. For ease of understanding, FIG. 8 shows the setting item name as it is as the setting item ID.
The set value (before change) is a data item in which the set value before the change is registered when the set value is changed on the component information setting screen 63.
The set value (after change) is a data item in which the changed setting value is registered.

The trouble flag is a data item indicating whether or not the screen operation caused the trouble. For example, it is assumed that a trouble occurs during production when the setting value of a certain setting item A is changed from B to C to produce the substrate P. Then, as a result of the operator investigating the cause of the trouble, it is assumed that the cause is that the setting value of the above-mentioned setting item A is changed from B to C. In this case, the operator sets a value indicating that the screen operation caused the trouble in the trouble flag of the operation log of the operation in which the setting value of the setting item A is changed from B to C (an example of the addition process). .. The value of the trouble flag is 0 or 1. 1 indicates that the screen operation caused the trouble, and 0 indicates that the screen operation did not cause the trouble. 1 is an example of quality information indicating that a trouble has occurred. The default value of the trouble flag is 0.

The operation table shown in FIG. 9 is the operation table of the feeder deceleration setting screen 64. The operation table of the feeder deceleration setting screen 64 has an operation ID, a set position number, a set value (before change), a set value (after change), and a trouble flag as data items.

The operation table shown in FIG. 10 is the operation table of the equipment setting screen 65. The operation table of the equipment setting screen 65 has an operation ID, a function ID, a set value (before change), a set value (after change), and a trouble flag as data items. The function ID is a number attached to the function provided by each facility. In order to facilitate understanding, the function name is shown as a function ID as it is in FIG.

(7) Operation log management method When the operation log management device 3 acquires the operation log from the device (change support device 4 or the operation unit of each facility) in which the operator is operating the screen, the acquired operation log is converted into a transition table. And whether or not the screen operation indicated by the operation log is a screen operation that may cause trouble is registered in the transition table and the operation table while being registered in the operation table. Judgment is made based on the operation log of (an example of the judgment process).

Specifically, in the operation log management device 3, the screen operation indicated by the acquired operation log is the screen operation indicated by another operation log in which the trouble flag is set to 1 (in other words, the cause of the trouble). It is determined whether or not it is similar to the screen operation), and if it is similar, it is determined that the screen operation may cause trouble.
Similar to the screen operation described above, there are cases where the absolute value of the difference between the set values is not more than a predetermined value and cases where the screen operation is the same. Each will be described below.

(7-1) When the absolute value of the difference between the set values is not more than the predetermined value For example, in the example shown in FIG. 8, the operator changed the nozzle descent amount of the component Ea from 3.31 mm to 3.34 mm. 1 is set in the trouble flag of the operation log when a trouble occurs and the nozzle descent amount is changed to 3.34 mm. In that case, it is assumed that the operator changes the nozzle descent amount setting value to 3.33 mm, which is close to 3.34 mm, for another type of component Eb having a shape similar to that of the component Ea. In this case, the changed set value of 3.33 mm is close to the set value of 3.34 mm that caused the trouble in the part Ea having a shape similar to that of the part Eb, and may cause the trouble. ..

Therefore, in the operation log management device 3, the absolute value of the difference between the operation log of the component E having a similar shape and the changed setting value of the operation log in which the trouble flag is set to 1 is not more than a predetermined value. In that case, it is determined that the screen operation is similar to the screen operation that caused the trouble.

First, the similarity of the component E will be described. The storage unit 52 of the operation log management device 3 stores a component information table (not shown) showing the shape of each type of component E. For ease of understanding, the shape of the part E is assumed to be a rectangular parallelepiped here. As shown in FIG. 11, here, the width in the left-right direction of the component E is defined as the dimension X, the width in the front-rear direction is defined as the dimension Y, and the width in the up-down direction is defined as the thickness Z. In the component information table (not shown), the dimensions X, Y, Z of each type of component E are registered as data representing the shape of the component E.

As shown in Table 1 below, the operation log management device 3 is set with a similar reference intersection. In the example shown in Table 1, the intersection of dimension X is changed by ± 30%, the intersection of dimension Y is changed by ± 20%, and the intersection of thickness is changed by ± 10%. The operation log management device 3 states that the component Eb is similar to the component Ea if the differences between the dimensions X, Y, Z of one component Eb and the dimensions X, Y, Z of another component Ea are all within the intersection. to decide.

The operation log management device 3 is an example of an operation log (a newly acquired operation log) in which a screen operation for changing a setting value of a certain setting item (here referred to as setting item D) of a certain component Eb is performed and the screen operation is performed. ) Is acquired, the component E having a shape similar to that of the component Eb is searched from the component information table. Then, for example, when the component Ea is searched for as the component E having a shape similar to that of the component Eb, the operation log management device 3 has a trouble flag in the operation log in which the setting value of the setting item D of the component Ea has been changed in the past. Judges whether or not there is an operation log for which 1 is set.

If there is an operation log in which the trouble flag is set to 1, the operation log management device 3 has the changed setting value of the component Eb and the changed setting value of the operation log in which the trouble flag is set to 1. It is determined whether or not the absolute value of the difference from and is equal to or less than the predetermined value. The predetermined value may be fixedly set, or may be a value corresponding to a predetermined% of the changed set value of the similar component Ea. When the absolute value of the difference described above is not more than a predetermined value, the operation log management device 3 determines that the screen operation is similar to the screen operation that caused the trouble.

When the operation log management device 3 determines that the screen operation is similar to the screen operation that caused the trouble, the operator performs the screen operation (change support device 4 or the operation unit of each facility). , Send a message indicating that the screen operation may cause trouble (in other words, the screen operation may deteriorate the quality of work). When the device receives a message, the device displays the received message on the screen. This notifies the operator. Notification to the operator may be performed by voice.
Here, the component information setting screen 63 has been described as an example, but the same applies to the feeder deceleration setting screen 64.

(7-2) When the screen operations are the same For example, it is assumed that the operator selects the surface mounter 14 which is the equipment selection screen 60 and changes the erroneous mounting prevention function from enabled to disabled on the equipment setting screen 65. In this case, the operation log management device 3 performs an operation log (in other words, the same screen operation) in which the operation log for enabling or disabling the erroneous mounting prevention function is performed from the operation logs of the equipment similar to the selected equipment. Operation log) is extracted. Here, the equipment similar to the selected equipment is, for example, when the selected equipment is the surface mounter 14, the similar equipment includes the selected surface mounter 14 itself and all other equipment. A surface mounter 14 is included. The same applies to other equipment.

The operation log management device 3 determines whether or not there is an operation log having a trouble flag of 1 in the extracted operation log (operation log in which an operation for enabling or disabling the erroneous mounting prevention function in similar equipment) is included. If there is an operation log in which the trouble flag is 1, it is determined that the screen operation is the same as the screen operation that caused the trouble. If the operation log management device 3 determines that the screen operation is the same as the screen operation that caused the trouble, the operation log management device 3 is a screen operation that may cause a trouble in the device in which the operator is operating the screen. Send a message indicating that.

(8) Effect of the embodiment According to the operation log management method according to the first embodiment, the screen operation indicated by the newly acquired operation log may cause a trouble (in other words, the quality of the work). It is judged based on other operation logs whether or not it is a screen operation that may be deteriorated). Therefore, when it is determined that the screen operation may cause a trouble, the operator can redo the screen operation so that the possibility of the trouble is reduced, so that the trouble can be suppressed. Therefore, it is possible to prevent troubles from occurring due to screen operations performed by the operator.

According to the above operation log management method, if it is determined that the screen operation may cause trouble, the operator performing the screen operation is notified that the screen operation may cause trouble. Therefore, it is possible to prevent the trouble from occurring by having the notified operator redo the screen operation so as to reduce the possibility that the trouble will occur.

According to the above operation log management method, a screen similar to the screen operation indicated by the operation log in which the trouble flag is set to 1 (that is, the operation log to which the quality information indicating that the quality of the work has deteriorated is added). By determining whether or not it is an operation, it is possible to determine whether or not it is a screen operation that may cause trouble.

According to the above operation log management method, after changing the screen operation indicated by the newly acquired operation log and the other operation logs for which the trouble flag is set to 1 By determining whether or not the absolute value of the difference from the set value of is equal to or less than a predetermined value, it is possible to determine whether or not the screen operation is similar to the screen operation indicated by other operation logs.

According to the above operation log management method, the changed setting value of the screen operation indicated by the newly acquired operation log is the changed setting value of the screen operation indicated by other operation logs in which the trouble flag is set to 1. By determining whether or not it is the same as the set value of, it is possible to determine whether or not the screen operation is similar to the screen operation indicated by other operation logs.

According to the above operation log management method, the quality information is information indicating whether or not a trouble has occurred in the work due to the screen operation, and the quality information indicating that the work quality has deteriorated is the information indicating that the trouble has occurred. Since it is quality information indicating that the screen operation has been performed, it is possible to suppress the occurrence of troubles due to screen operations.

<Embodiment 2>
The operation log management device 3 according to the second embodiment may deteriorate the quality of the work when the screen operation contradicts the screen operation in which the quality of the work of mounting the component E on the board P is improved. Notify the operator that it is a screen operation (an example of the first notification process). In the following description, the work quality includes the adsorption rate when the component E is adsorbed by the adsorption head (the ratio of the number of successful adsorptions to the number of attempts to adsorb) and the normal mounting rate (relative to the number of attempts to mount). The ratio of the number of times that the component E can be mounted without mistake) will be described as an example. The adsorption rate and the normal loading rate are examples of the success rate of the work.

The operation system table shown in FIG. 12 is an operation system table of the component information setting screen 63. The operation system table of the component information setting screen 63 according to the second embodiment has an adsorption rate (adsorption rate before change, adsorption rate after change) instead of the trouble flag of the operation system table according to the first embodiment.
In the case of the component Ea shown in FIG. 12, when the nozzle lowering amount is changed from 3.31 mm to 3.34 mm, the adsorption rate is improved from 99.93% to 99.96%. In this case, since the adsorption rate is improved by making the nozzle lowering amount larger than 3.31 mm, there is a high possibility that the adsorption rate will decrease if the nozzle lowering amount is smaller than 3.31 mm. Therefore, for the part E whose shape is similar to that of the part Ea, the set value is 3.31 mm (the set value before the change of other screen operations whose work quality is improved by increasing the set value as compared with the set value before the change). If a screen operation to be made smaller is performed, it can be said that the screen operation is a screen operation contradictory to other screen operations having an improved adsorption rate. The screen operation in which the set value is smaller than 3.31 mm can be said to be the screen operation in the direction in which the quality of work is deteriorated.

In the case of the component Ec shown in FIG. 12, when the nozzle descent amount is changed from 3.33 mm to 3.29 mm, the adsorption rate is improved from 99.90% to 99.91%. In this case, since the adsorption rate is improved by making the nozzle lowering amount smaller than 3.33 mm, there is a high possibility that the adsorption rate will decrease if the nozzle lowering amount is made larger than 3.33 mm. Therefore, if a screen operation is performed to make the set value larger than 3.33 mm for the part E whose shape is similar to that of the part Ec, the adsorption rate is improved by making the set value smaller than before the change. Since the setting value is changed to a value larger than the setting value before the change of the screen operation, it can be said that the screen operation is a screen operation contradictory to other screen operations having an improved adsorption rate. A screen operation in which the set value is larger than 3.33 mm can be said to be a screen operation in a direction in which the quality of work deteriorates.

The operation table shown in FIG. 13 is the operation table of the equipment setting screen 65. The operation table of the equipment setting screen 65 according to the second embodiment also has work quality (normal mounting rate before change, normal mounting rate after change) instead of the trouble flag. In the case of the screen operation of ID006 shown in FIG. 13, when the erroneous mounting prevention function is changed from invalid to enabled, the normal mounting rate is improved from 99.94% to 99.97%. Therefore, if a screen operation for enabling or disabling the erroneous mounting prevention function is performed, it can be said that the screen operation is a screen operation contradictory to other screen operations for which the normal mounting rate has been improved. The change from enabling to disabling the function can also be said to be a screen operation in the direction of degrading the quality of work.

The operation log management device 3 according to the second embodiment is a device (change support device 4 or an operation unit of each facility) in which an operator performs a screen operation when a screen operation is performed in a direction in which the quality of work deteriorates. Is sent a message indicating that the screen operation may reduce the quality of work.

Here, in the case of the component Ec shown in FIG. 12, when the nozzle descent amount is changed from 3.33 mm to 3.29 mm, the adsorption rate is improved from 99.90% to 99.91%. However, for example, if the reference value of the adsorption rate is 99.95%, the changed adsorption rate is less than the reference value. In this case, it is assumed that the operator changes the nozzle descent amount to 3.30 mm, which is a set value smaller than 3.33 mm, for the component E having a shape similar to that of the component Ec. This screen operation is not a screen operation in the direction of degrading the quality of work, but since it is a value close to 3.29 mm, the adsorption rate may not reach the reference value. Therefore, even if the operation log management method is not a screen operation in the direction of degrading the work quality, if the absolute value of the difference between the changed set value and 3.29 mm is less than the predetermined value, the work is performed. Notify the operator that the success rate (adsorption rate) may not reach the reference value (an example of the second notification step).

According to the operation log management method according to the second embodiment, the operation log to which the quality information indicating that the work quality (adsorption rate, normal loading rate) has been improved (the adsorption rate after change is higher than the adsorption rate before change) is added. The quality of work may deteriorate by determining whether or not the screen operation conflicts with the screen operation indicated by the operation log or the operation log in which the normal mounting rate after change is higher than the normal mounting rate before change). It is possible to judge whether or not there is a certain screen operation.

According to the above operation log management method, the quality information includes the pre-change success rate (pre-change adsorption rate, pre-change normal mounting rate), which indicates the success rate of the work before the operation is changed, and the work after the operation is changed. The information indicating the success rate after change (adsorption rate after change, normal loading rate after change), which indicates the success rate of, and the quality information indicating that the quality of work has improved, the success rate after change is the success rate before change. Since it is higher quality information, it can be determined whether or not it is quality information indicating that the quality of work has improved.

According to the above operation log management method, conflicting screen operations are changed to smaller setting values than the setting values before the change of other screen operations whose work quality is improved by increasing the setting values compared to before the change. It is at least one of the screen operation and the screen operation of changing to a setting value larger than the setting value before the change of other screen operations whose work quality is improved by making the setting value smaller than that before the change. When the work quality is improved by making it larger than the setting value before the change, it can be said that making it smaller than the setting value before the change is a screen operation that contradicts the screen operation with the improved work quality. On the contrary, when the work quality is improved by making it smaller than the setting value before the change, making it larger than the setting value before the change is a screen operation that contradicts the screen operation with the improved work quality. I can say.

According to the above operation log management method, conflicting screen operations are erroneously installed when the normal installation rate (work quality, work success rate) is improved by enabling the erroneous installation prevention function in other screen operations. This is a screen operation that disables the prevention function. When the work quality is improved by enabling the erroneous mounting prevention function, disabling the erroneous mounting prevention function can be said to be a screen operation that contradicts the screen operation with the improved work quality.

According to the above operation log management method, when the operator performs a screen operation, the success rate (adsorption rate, normal mounting rate) of the changed work of other screen operations similar to the screen operation meets the reference value. If not, the operator is notified that the success rate of the work may not reach the reference value. Therefore, the operator repeats the screen operation, and the success rate of the work is likely to reach the reference value.

<Embodiment 3>
The operation log management device 3 according to the third embodiment reproduces the screen operation by displaying the screen operation performed by the operator on the display unit 53 in chronological order based on the operation log.
Reproduction of the screen operation based on the operation log will be described with reference to FIG. When the operation log management device 3 is instructed to reproduce the screen operation, the operation log management device 3 displays the screen operation reproduction screen 70 shown in FIG. Screen operation The playback screen 70 has a start time 70A, an end time 70B, a production line number 70C, an equipment number 70D, a playback format selection field 70E (live or history), a play / stop button 70F, a rewind button 70G, and a fast forward button 70H. Etc. are displayed.

The start time 70A and the end time 70B are items for specifying whether to reproduce the screen operation performed between what time and what time.
The production line number 70C is an item to which the number of the production line 2 to be reproduced of the screen operation is designated.

The equipment number 70D is an item to which the equipment number of the equipment to be reproduced for screen operation is designated among the equipment constituting the designated production line 2. "All" can be specified for the equipment number. When "all" is specified, the screen operation performed on all the equipment constituting the production line 2 indicated by the specified production line number is the target of reproduction.
The playback format selection field 70E is an item for specifying whether to play back the screen operation performed by the operator in real time (live playback) or to play back the screen operation performed in the past after the fact (history playback). Is.

Screen operation When the operator presses the play / stop button 70F on the playback screen 70, the operation screens are displayed side by side in the order of the screen IDs registered in the transition system table. On the screen operation playback screen 70, the earlier the operation time is, the more it is displayed on the left side. Immediately after displaying each operation screen, the setting value before the change is displayed in each setting item of each operation screen. The equipment number of the equipment to be changed is displayed on each operation screen.

(1) History playback and live playback As described above, there are two types of screen operation playback: live playback and history playback. Each will be described below.

(1-1) History reproduction History reproduction refers to the ex post facto reproduction of screen operations performed in the past on the operation log management device 3 based on the transition system log and the operation system log. For example, when a trouble occurs, the operator replays the screen operation in history in order to determine whether or not the change in the set value was the cause of the trouble.
Specifically, the operation log management device 3 extracts the operation screen ID from the transition system table based on the conditions (start time, end time, production line number, etc.) specified on the screen operation playback screen 70, and extracts the operation screen ID. The operation screen indicated by the operation screen ID is displayed on the screen operation playback screen 70. Then, the operation log management device 3 displays the screen operations performed on each operation screen in chronological order based on the operation log registered in the operation system table (an example of the reproduction process).

For example, in the operation system log shown in FIG. 8, the nozzle descent deceleration rate is changed from 19% to 20% by the screen operation of ID001, and then the nozzle descent amount is changed from 3.31 mm to 3.34 mm. .. In this case, when the play / stop button 70F is pressed, the operation log management device 3 displays the values before the change in the nozzle descent deceleration rate and the nozzle descent amount of the component selection screen 62 for the first second, for example. When the second elapses, the nozzle descent deceleration rate is changed to 20%. Then, when another 1 second elapses, the nozzle descent amount is changed to 3.34 mm. As a result, the screen operation is reproduced.

However, it may be difficult for the operator who is looking at the screen operation reproduction screen 70 to know which setting item the setting value has been changed. Therefore, it is preferable that the operation log management device 3 identifiablely displays which setting item the setting value has been changed. Specifically, for example, the set value before the change may be displayed in black characters (or numbers), and the set value after the change may be displayed in red characters (or numbers).

The method of identifiablely displaying which setting value of which setting item has been changed is not limited to this. For example, the background color of the setting item whose setting value has been changed may be displayed identifiable by displaying it in a color different from the background color of the setting item whose setting value has not been changed, or the setting value has been changed. The set items may be displayed in an identifiable manner by enclosing them in a red frame. Alternatively, the changed setting value may be displayed in red letters (or numbers) and in bold letters.

(1-2) Live playback Live playback means that every time an operation log is registered in a transition table or an operation table, the screen operation indicated by the operation log is displayed on the display unit 53 (playback process). An example). For example, an observer may monitor an operator's screen operation so that an unfamiliar operator does not perform an erroneous screen operation. In live playback, every time the operator performs a screen operation and the operation log is registered, the screen operation indicated by the operation log is displayed, so although there is a slight time difference, the observer almost performs the screen operation performed by the operator. Can be monitored in real time.

(2) Effect of the embodiment According to the operation log management method according to the third embodiment, the screen operation is reproduced by displaying the screen operation indicated by the operation log on the display unit 53, so that when the operation log is analyzed as it is. In comparison, it becomes easier to identify the screen operation that caused the trouble.

According to the above operation log management method, the screen operation is played back in real time, so that the observer who monitors the screen operation by the operator monitors the played screen operation in real time, and the quality of the work is deteriorated. If it is determined, the possibility that the quality of work is deteriorated can be reduced by notifying the operator to that effect.

<Other embodiments>
The techniques disclosed herein are not limited to the embodiments described above and in the drawings, and for example, the following embodiments are also included in the technical scope disclosed herein.

For example, the substrate working device may be a screen printing machine 11, a printing inspection machine 12, a dispenser 13, a post-mounting visual inspection machine 15, a reflow device 16, a post-curing visual inspection device 17, and the like.

(2) In the above embodiment, the adsorption rate has been described as an example of the success rate of the work, but the success rate is not limited to this. For example, when the component E is sucked by the suction nozzle 28B, the position of the component E with respect to the suction nozzle 28B may shift. When the case where the misalignment amount of the component E with respect to the suction nozzle 28B is defined as success is defined as success, the success rate is determined by the misalignment amount when the operation of sucking the component E by the suction nozzle 28B is performed a plurality of times. The ratio may be less than or equal to the value. Further, for example, when the component E sucked by the suction nozzle 28B is mounted on the substrate P, the position of the component E with respect to the substrate P may shift. When the case where the amount of misalignment of the component E with respect to the substrate P is equal to or less than a predetermined value is defined as success, the success rate is the case where the operation of mounting the component E sucked by the suction nozzle 28B on the board P is performed a plurality of times. The ratio may be such that the amount of misalignment is equal to or less than a predetermined value.
