Description

This specification relates to a maintenance notification system that notifies maintenance guidance for a unit used in a mounting apparatus.

Patent Document 1 discloses a component mounting apparatus that mounts electronic components on a board. The head unit of the component mounting apparatus is replaceable, and a plurality of head units can be attached to the component mounting apparatus. The component mounting apparatus stores operating time data for each of the plurality of head units. The user understands the frequency of use of each head unit and performs maintenance on each head unit.

JP2009-272652A

In order to prevent non-performance of maintenance, a system that notifies maintenance instructions is desired. For example, it is assumed that the component mounting apparatus of Patent Document 1 notifies maintenance of each head unit when the operating time of each head unit is longer than a predetermined period.

In this configuration, the timing at which the operating time of the first head unit among the plurality of head units exceeds the predetermined period is the timing when the operating time of the second head unit among the plurality of head units exceeds the predetermined period. It is determined regardless of the timing of exceeding the limit. That is, the timing of notification of maintenance for the first head unit is unrelated to the timing of notification of maintenance of the second head unit. For this reason, it is difficult for the user to predict the timing at which the maintenance of each of the plurality of head units will be notified. If it is difficult to predict the timing when maintenance will be notified, it becomes difficult for users to plan maintenance.

This specification provides a technique for making maintenance planning easier.

The maintenance notification system disclosed in this specification includes a notification unit (14) that notifies maintenance guidance for at least one unit of a plurality of units used in a mounting apparatus that mounts components on a board; a notification counter (34) that counts the time for measuring the notification timing at which the notification unit notifies the guidance, and a notification counter (34) that repeatedly arrives at a cycle of . A unit counter (36) that counts a count value indicating the usage status of the unit while it is being used, and a control section (32) that controls the notification section; When the counted value is greater than or equal to a predetermined value indicating that maintenance of the unit corresponding to the unit counter is recommended, and the time counted by the notification counter indicates the notification timing, causing the notification unit to execute the guidance for maintenance of the unit corresponding to the unit counter, the count value counted by the unit counter is equal to or greater than the predetermined value, and the time counted by the notification counter A first notification control unit (32) is provided that does not cause the notification unit to execute the guidance for maintenance of the unit corresponding to the unit counter when the unit counter does not indicate the notification timing.

Further, this specification also discloses a control method for controlling a notification unit (14) that notifies maintenance guidance for at least one unit among a plurality of units used in a mounting apparatus that mounts components on a board. do. In the control method, the notification counter (34) counts a time for measuring the notification timing at which the notification section notifies the guidance, and the notification timing repeatedly arrives at a predetermined period. (34), and a unit counter (36) for counting a count value indicating the usage status of the unit while the unit is being used by the mounting apparatus for each of the plurality of units, The control method includes: the count value counted by the unit counter is equal to or greater than a predetermined value indicating that maintenance of the unit corresponding to the unit counter is recommended, and the time counted by the notification counter indicates the arrival of the predetermined period, causing the notification unit to execute the guidance for maintenance of the unit corresponding to the unit counter, and when the count value counted by the unit counter is equal to or greater than the predetermined value. and, if the time counted by the notification counter does not indicate the arrival of the predetermined period, the notification unit does not execute the guidance for maintenance of the unit corresponding to the unit counter.

According to the above configuration, maintenance guidance for each of the plurality of units is provided at a predetermined period, and is not provided at timings other than the predetermined period. Therefore, the user can easily predict the timing at which maintenance guidance for each of the plurality of units will be notified, making it easier for the user to plan maintenance.

A schematic diagram of a component mounting apparatus is shown. A block diagram of a component mounting apparatus is shown. A specific case C1 realized by the component mounting apparatus is shown. A specific case C2 realized by the component mounting apparatus is shown. A comparative example is shown.

The main features of the embodiment described below will be listed. The technical elements described below are independent technical elements that exhibit technical utility alone or in various combinations, and are limited to the combinations described in the claims as filed. It's not a thing.

(Feature 1) When there is a unit for which the count value counted by the unit counter exceeds a predetermined upper limit value that is larger than the predetermined value, the control unit is configured to control the count value counted by the notification counter. The apparatus may further include a second notification control section (32) that causes the notification section to execute the guidance for maintenance of the unit corresponding to the unit counter, regardless of whether the time indicates the notification timing or not.

A situation in which the counter value exceeds the upper limit value means that maintenance of the unit has not been performed for a relatively long time. According to the above configuration, it is possible to prevent a situation in which maintenance of the unit is not performed from continuing for a relatively long time.

(Feature 2) For each of the plurality of maintenance items, the predetermined value indicating that the maintenance indicated by the maintenance item is recommended is set,
When the count value is greater than or equal to the predetermined value set for a specific maintenance item among the plurality of maintenance items, and the time counted by the notification counter indicates the notification timing; , the notification unit may be caused to execute the guidance on maintenance indicated by the specific maintenance item.

According to the above configuration, there is a situation where there are multiple maintenance items (for example, maintenance at a first location within the unit and maintenance at a second location different from the first location within the unit). notifications appropriate to the situation).

(Component mounting device 2; Figures 1 and 2)
The component mounting device 2 is a device that manufactures a circuit board by mounting electronic components on a board. The component mounting apparatus 2 includes a mounting mechanism 12, a cassette 16, a notification section 14, a control device 30, and a support stand 40.

The component feeder 100 can be attached to and detached from the cassette 16. Component feeder 100 accommodates a plurality of electronic components. ID "f01" is assigned to the parts feeder 100.

In place of the component feeder 100, a component feeder 102 can be attached to and removed from the cassette 16. ID "f02" is assigned to the parts feeder 100. One component feeder out of a plurality of component feeders including component feeders 100 and 102 is attached to the cassette 16 . When a specific component feeder (for example, 100) is mounted on the cassette 16, the component mounting apparatus 2 acquires an ID (for example, "f01") from the specific component feeder. The component mounting apparatus 2 recognizes the component feeder attached to the cassette 16 based on the acquired ID. Note that the component mounting apparatus 2 is provided with a plurality of cassettes including the cassette 16, but in the drawing, one cassette 16 is shown and the other cassettes are omitted. In the production of circuit boards, some or all of the cassettes may be used.

The mounting mechanism 12 mounts electronic components supplied from a component feeder (for example, 100) onto a substrate on a support base 40. A nozzle 12a is attached to the tip of the mounting mechanism 12 for sucking electronic components supplied from a component feeder. There are various types of nozzles 12a. A specific type of nozzle 12a is selected from among various nozzles 12a depending on the type of electronic component to be sucked.

The notification unit 14 notifies various guidance. The notification unit 14 is, for example, a display. In addition, in a modified example, the notification unit 14 may be, for example, a speaker that outputs audio guidance, a lamp that lights up a warning light, or the like.

The control device 30 controls each section 12, 14, 16, 40, etc. of the component mounting apparatus 2. The control device 30 is composed of a CPU, memory, and the like. The control device 30 further includes a notification counter 34 and a unit counter 36, and a notification program 32 and an upper limit period 38 are stored in the memory of the control device 30. The notification counter 34 counts the time for the notification unit 14 to notify maintenance guidance, and when the time counted by the notification counter 34 is a notification timing that repeatedly arrives at a predetermined period (for example, 100 hours), The control device 30 causes the notification unit 14 to execute maintenance guidance. In other words, the notification counter 34 counts the time for measuring the notification timing. The notification counter 34 starts counting time, for example, when the component mounting apparatus 2 is started to be used. Further, for example, the time counting by the notification counter 34 may be started at the same time as the component mounting apparatus 2 is initialized.

The unit counter 36 counts the usage period of a component feeder (for example, 100). The period of use indicates the total period during which the component feeder is attached to the cassette 16 and is actually in operation after maintenance of the component feeder is performed. The usage period is reset when maintenance of the component feeder is performed. In a modified example, the period of use indicates the total period during which the component feeder is attached to the cassette 16, and may also include a period during which the component feeder is attached to the cassette 16 but the component feeder is temporarily stopped. Further, the unit counter 36 may cooperate with a system (not shown) that manages whether or not maintenance is to be performed. Further, the component mounting apparatus 2 may manage whether or not maintenance is to be performed.

For example, when the component feeder 100 is installed in the cassette 16 among a plurality of component feeders, the unit counter 36 of the component feeder 100 (i.e., the counter indicating the usage period of ID "f01") and the notification counter 34 are Perform counting. The notification counter 34 performs counting regardless of which component feeder among the plurality of component feeders is attached to the cassette 16.

The CPU of the control device 30 executes the following processing according to the notification program 32. When the time counted by the notification counter 34 indicates the notification timing, the CPU determines whether or not to notify the parts feeder maintenance guide. Specifically, the CPU determines, for each of the plurality of unit counters 36 corresponding to the plurality of component feeders, whether the usage period counted by the unit counter 36 is longer than a predetermined period (for example, 100 hours). to judge. The predetermined period is a period indicating that maintenance of the component feeder is recommended. When it is determined that the usage period counted by the specific unit counter 36 (for example, the unit counter 36 of the parts feeder 100) is equal to or longer than a predetermined period, the CPU controls the unit corresponding to the specific unit counter 36 (for example, the unit counter 36 of the parts feeder 100). The notification unit 14 is caused to perform maintenance guidance for the parts feeder 100). On the other hand, when the CPU determines that the usage period counted by the specific unit counter 36 is less than a predetermined period, the CPU sends maintenance guidance for the unit corresponding to the specific unit counter 36 to the notification unit 14. Don't let it run. Here, the "predetermined period" is set in advance by the vendor of the component mounting apparatus 2. Note that the "predetermined period" may be set by the user.

Further, the upper limit period 38 indicates the upper limit value of each usage period, and is, for example, 180 hours. When the usage period exceeds the upper limit period, the CPU of the control device 30 forcibly notifies maintenance guidance for the component feeder, regardless of whether the time counted by the notification counter 34 indicates the notification timing. The upper limit period 38 is set in advance by the vendor of the component mounting apparatus 2.

(Specific case C1; Figure 3)
A specific case C1 in which the CPU of the control device 30 executes according to the notification program 32 will be described. In the following, the processing executed by the CPU of the control device 30 in accordance with the notification program 32 will be described with the notification program 32 as the main subject.

In this case, after the parts feeder 100 (i.e., ID "f01") has been operating for 70 hours, the parts feeder 102 (i.e., ID "f01") is attached to the cassette 16, and the parts feeder 102 has been in operation for 80 hours. and operate. Thereafter, the component feeders 100 and 102 are alternately loaded into the cassette 16, with the component feeder 100 operating for 60 hours and the subsequent 60 hours, and the component feeder 102 operating for 90 hours and the subsequent 80 hours. Be in operation.

The notification program 32 determines the usage period of the unit counter 36 with ID "f01" (hereinafter referred to as "usage period "f01") when the time counted by the notification counter 34 indicates the notification timing "100 hours". is a predetermined period of "100 hours" or more. At present, the usage period "f01" is 70 hours, which is less than the predetermined period "100 hours". The notification program 32 determines not to cause the notification unit 14 to notify maintenance guidance for the parts feeder 100. Further, the notification program 32 determines whether the usage period of the unit counter 36 with ID "f02" (hereinafter referred to as "usage period "f02") is longer than a predetermined period of "100 hours". At present, the usage period "f02" is 30 hours, which is less than the predetermined period "100 hours". The notification program 32 determines not to cause the notification unit 14 to notify the maintenance guidance for the parts feeder 102.

Next, when the time counted by the notification counter 34 indicates the next notification timing of "200 hours", the notification program 32 determines whether the usage period "f01" is longer than the predetermined period "100 hours". to decide. At present, the usage period "f01" is 120 hours (i.e., 70+50 hours), which is longer than the predetermined period "100 hours". The notification program 32 determines to cause the notification unit 14 to notify maintenance guidance for the parts feeder 100. Then, the notification program 32 resets the usage period "f01" when maintenance of the parts feeder 100 is performed. Further, the notification program 32 determines whether the usage period "f02" is longer than a predetermined period "100 hours". At present, the usage period "f02" is 80 hours, which is less than the predetermined period "100 hours". The notification program 32 determines not to cause the notification unit 14 to notify the maintenance guidance for the parts feeder 102.

Next, when the time counted by the notification counter 34 indicates the next notification timing of "300 hours", the notification program 32 determines whether the usage period "f01" is longer than the predetermined period "100 hours". to decide. The usage period "f01" has been reset by maintenance performed at the notification timing "200 hours". Therefore, the notification program 32 determines that the period of use "f01" is less than the predetermined period "100 hours" and determines not to cause the notification unit 14 to notify maintenance guidance for the parts feeder 100. Further, the notification program 32 determines whether the usage period "f02" is longer than a predetermined period "100 hours". At present, the usage period "f02" is 170 hours (80+90 hours), which is longer than the predetermined period "100 hours". The notification program 32 determines to cause the notification unit 14 to notify maintenance guidance for the parts feeder 102. Then, the notification program 32 resets the usage period "f02" when maintenance of the parts feeder 102 is performed.

For example, a comparative example that does not include the notification counter 34 is assumed. In this comparative example, the notification program 32 notifies maintenance instructions for the parts feeder 100 when the usage period "f01" exceeds the predetermined period "100 hours", and when the usage period "f02" exceeds the predetermined period "100 hours". If the time exceeds "time", maintenance guidance for the parts feeder 102 is notified. FIG. 5 shows a specific case of a comparative example, in which component feeders 100 and 102 are used according to the same schedule as in FIG. 3.

As shown in FIG. 5, in the comparative example, maintenance of the component feeder 100 is guided at a timing of 180 hours. Next, maintenance of the component feeder 102 is guided at a timing of 230 hours, and maintenance of the component feeder 102 is guided again at a timing of 390 hours. As shown in FIG. 5, in the comparative example, maintenance guidance is chaotic. Users have to deal with chaotically guided maintenance, and there is also the possibility that users may shut down the production line. Furthermore, the chaotic maintenance guidance makes it difficult for the user to plan maintenance.

As shown in FIG. 3, according to the configuration of this embodiment, maintenance of each of the plurality of component feeders is guided when the time counted by the notification counter 34 indicates the notification timing. On the other hand, if the time counted by the notification counter 34 does not indicate the notification timing, no maintenance is advised for any of the plurality of component feeders. Therefore, the user can prepare for maintenance in advance according to the maintenance guidance notified according to a predetermined cycle, and it becomes easier to plan maintenance.

The maintenance notified by the notification program 32 is, for example, cleaning of the component feeder, the nozzle 12a for sucking electronic components, etc., and is maintenance that should be performed at relatively short intervals. Even if such maintenance is performed a little later than the predetermined period of "100 hours", it will not have a major impact on the manufacture of circuit boards by the component mounting apparatus 2. In this embodiment, priority is given to the ease with which the user can formulate a maintenance plan over strict notification within a predetermined period of "100 hours."

Note that maintenance such as refueling, inspection, and component replacement that should be performed at relatively long intervals (for example, 1000 hours) may have a large impact on the production of circuit boards by the component mounting apparatus 2, so this example Instead of a notification, a strict notification like the comparative example in FIG. 5 may be adopted. In addition, in a modified example, the notification of this embodiment may also be adopted for refueling, parts replacement, etc.

(Specific case C2; Figure 4)
A specific case C2 realized by the notification program 32 will be explained. Also in this case, the component feeders 100 and 102 are alternately mounted on the cassette 16. The parts feeder 100 operates for 99 hours, then 91 hours, and 80 hours, and the parts feeder 102 operates for 10 hours and then 40 hours.

When the time counted by the notification counter 34 indicates the notification timing "100 hours", the notification program 32 determines whether the usage period "f01" is longer than the predetermined period "100 hours". At present, the usage period "f01" is 99 hours, which is less than the predetermined period "100 hours". The notification program 32 determines not to cause the notification unit 14 to notify maintenance guidance for the parts feeder 100. Further, the notification program 32 determines whether the usage period "f02" is longer than a predetermined period "100 hours". At present, the usage period "f02" is one hour, which is less than the predetermined period "100 hours". The notification program 32 determines not to cause the notification unit 14 to notify the maintenance guidance for the parts feeder 102.

In this case, the component feeder 102 is installed for only 10 hours, and immediately after that, the component feeder 100 is installed again. The usage period "f01" exceeds the upper limit period "180 hours" before the time counted by the notification counter 34 indicates the next predetermined notification timing "200 hours". Therefore, the notification program 32 causes the notification unit 14 to execute maintenance guidance for the component feeder 100 even if the time counted by the notification counter 34 does not indicate the notification timing.

According to this case, it is possible to prevent the maintenance guidance for the component feeder 100 from not being notified for a relatively long period in which the usage period exceeds the upper limit period 38. In other words, it is possible to prevent the maintenance of the component feeder 100 from continuing for a relatively long time.

(correspondence)
The component mounting apparatus 2 is an example of a "maintenance notification system". The component mounting apparatus 2, the plurality of component feeders, the notification section 14, the notification counter 34, the unit counter 36, and the upper limit period 38 are "mounting apparatus", "multiple units", "notification section", and "notification counter", respectively. ”, “unit counter”, and “predetermined upper limit value”. The predetermined period "100 hours" and the predetermined period "100 hours" are examples of the "predetermined period" and "predetermined period", respectively. A CPU that operates according to the notification program 32 is an example of a "control unit", a "determination unit", a "first notification control unit", and a "second notification control unit".

Points to note regarding the image processing apparatus described in the embodiment will be described. The "multiple units" may be, for example, a plurality of other units (eg, nozzle 12a, camera, etc.) that can be attached to and detached from the component mounting apparatus 2. Furthermore, the "multiple units" may be units built into the component mounting apparatus 2, rather than units that are repeatedly mounted on and removed from the component mounting apparatus 2. The unit may be, for example, a transport device that transports the board to the support stand of the component mounting apparatus 2, an actuator that drives the mounting mechanism 12 in the horizontal direction, or the like.

At least some of the "notification section", "notification counter", "unit counter", and "control section" are connected to an external device different from the component mounting apparatus 2 (for example, a PC or a system that manages the component mounting apparatus 2). etc.) may be used. Furthermore, the "unit counter" may be built into a unit (eg, component feeder 100).

The "predetermined period" is not limited to "100 hours" in the embodiment. The "predetermined cycle" may be appropriately set by the user according to the maintenance plan, or may be determined in advance by the vendor of the component mounting apparatus 2.

The notification counter 34 may stop when the component mounting apparatus 2 is stopped, or may continue even when the component mounting apparatus 2 is stopped. In modification A in which the notification counter 34 stops when the component mounting apparatus 2 stops, the user can plan maintenance according to the actual operating status of the component mounting apparatus 2. On the other hand, in modification B in which the notification counter 34 continues even when the component mounting apparatus 2 is stopped, the user can plan maintenance according to the date and time. Further, in another modification, the user may be allowed to select either the count of modification A or the count of modification B.

The "count value" is not limited to the usage period of the unit, but may also be the number of times the unit is used. For example, if the unit is the nozzle 12a, the number of times the nozzle 12a suctions an electronic component may be counted as the number of uses. Since the number of times the nozzle 12a attracts water per unit time varies, the number of times the nozzle 12a is used can more appropriately indicate the usage status of the nozzle 12a than the period of use. In another modification, the user may select either the period of use or the number of times of use as the count value of the unit counter 36.

Further, there are various maintenance items such as cleaning, inspection, and replacement, and there are also various maintenance points such as the upper part, the lower part, and the inside. For example, there may be a difference in recommended maintenance period between the item "Cleaning of the upper part" and the item "Cleaning of the lower part." In order to deal with such a situation, a predetermined period may be set for each of a plurality of maintenance items to indicate that the maintenance indicated by the maintenance item is recommended. Then, the notification program 32 determines that the usage period is longer than a predetermined period set for a specific maintenance item among the plurality of maintenance items, and the time counted by the notification counter 34 indicates the notification timing. In some cases, the notification unit 14 may be caused to perform maintenance guidance indicated by a specific maintenance item.

The "predetermined period" may be another time (for example, 120 hours) different from 100 hours. The embodiment is an example in which the "predetermined period" is the same as the "predetermined period," but the above modification is an example in which the "predetermined period" is different from the "predetermined period."

Case C2 in FIG. 4 may not be executed. In this modification, the "second notification control unit" can be omitted.

Further, the technical elements described in this specification or the drawings exhibit technical usefulness singly or in various combinations, and are not limited to the combinations described in the claims as filed. Furthermore, the techniques illustrated in this specification or the drawings simultaneously achieve multiple objectives, and achieving one of the objectives has technical utility in itself.
