Description

  The present invention relates to an electronic component mounting apparatus for notifying a maintenance management time before a main apparatus breaks down, and a maintenance management time notification method.

2. Description of the Related Art Conventionally, there is an electronic component mounting apparatus that mounts an electronic component (hereinafter simply referred to as a component) on a printed circuit board (hereinafter simply referred to as a substrate) carried into a main body device to produce a board unit.
The electronic component mounting device uses a suction nozzle (hereinafter simply referred to as a nozzle) that is interchangeably held at the tip of the mounting head to suck the component supplied from the component supply device, and the component sucked by the component camera After recognizing and checking the image, correcting the position, and then mounting on the substrate, the substrate unit is produced.

  In the electronic component mounting apparatus, as a mechanism for executing the production process of the substrate unit, a motor and a ball screw, a motor, a pulley, a belt, and the like that drive the mounting head in the X, Y, Z, and θ directions. There are a rotational drive system mechanism section and an actuator system mechanism section that supports the component supply operation of the component supply apparatus.

Conventionally, maintenance management of these mechanism parts has been performed by exchanging the parts of the failure part after a failure has occurred in each mechanism part.
However, when a component part is replaced after the mechanical part has mechanically failed as described above, the production line must be stopped immediately for the replacement operation. Stopping the production line in the middle of production is problematic because it requires a great deal of adjustment for resuming production.

  Moreover, there are many cases in which a failed part cannot be identified immediately, and there is a possibility that a problem that causes a reduction in production efficiency, such as spending a lot of time to find the failed part, may occur. Furthermore, there is a possibility that it is determined that a failure has occurred after producing a large number of poor quality parts, even though a failure has occurred.

In order to solve these problems, in electronic devices such as electronic component mounting devices, when a failure occurs in a control device, drive device, or sensor device, the failure location is automatically identified to improve work efficiency. There has been proposed a self-diagnosis device for failure points. (For example, refer to Patent Document 1.)
In addition, in order to avoid a fatal failure in which an electronic component mounting device including a computer device cannot be used due to the end of its storage life, a storage device life diagnosis method has been proposed. (For example, see Patent Document 2.)
In addition, there has been proposed a degradation diagnosis apparatus that periodically measures the operating state of a facility with a measuring instrument installed in the facility and estimates the degradation of the facility and the trouble-causing part or component based on the collected measurement data. (For example, refer to Patent Document 3.)
Japanese Patent Laid-Open No. 06-276000 ([Summary], FIG. 1) JP 2004-348332 A ([Summary], FIGS. 4 and 6) JP 2004-227357 A ([Summary], FIG. 1)

  However, the self-diagnosis device of Patent Document 1 contributes to the improvement of work efficiency in terms of automatically specifying the failure location, but since the specification of the failure location is a process performed after the failure occurs, Problems that come from sudden line stops cannot be resolved.

  In addition, the life diagnosis method of Patent Document 2 can avoid a problem caused by a sudden stop of the production line in terms of predicting a time when the life is exhausted before a failure occurs. However, it is difficult to apply to other components.

And 16 and a substrate recognition camera 22.

As will be described in detail later, the substrate recognition camera 22 also serves as a nozzle identification camera that reads an identification symbol given to the nozzle by marking in the present invention.
Each of the two mounting heads 16 can move up and down in the Z-axis direction (vertical direction) and can rotate in the θ-axis direction (360 ° direction). A nozzle 24 is attached to each end of the mounting head 16.

  The work head 15 is freely moved back and forth and right and left by the Y-axis rail 13 and the X-axis rail 14 described above. Thereby, the nozzle 24 can be moved back and forth, right and left in each work area via the work head 15 and the mounting head 16, can be moved up and down, and can be rotated in a 360 ° direction.

  FIG. 3 is a system block diagram of the electronic component mounting apparatus 1 configured as described above. As shown in the figure, the electronic component mounting apparatus 1 includes a CPU 35 and a control unit including an i / o (input / output) control unit 37 and an image processing unit 38 connected to the CPU 35 via a bus 36. A memory 39 is connected to the CPU 35. The memory 39 includes a program area and a data area (not shown).

  Further, the i / o control unit 37 is attracted to the substrate illumination device 28 for illuminating the component mounting position of the substrate 8 (see FIG. 1B) and the nozzle 24 (see FIG. 2) of the mounting head 16. An LED illuminator 27 that is integrated with the component recognition camera 19 for illuminating the component 31 is connected via an illumination control unit 40.

  Further, the i / o control unit 37 includes four X-axis motors 41, four Y-axis motors 42, eight Z-axis motors 43, and eight θ axes via respective amplifiers (AMP). A motor 44 is connected. The X-axis motor 41 drives the work head 15 in the X-axis direction via the X-axis rail 14, and the Y-axis motor 42 drives the X-axis rail, that is, the work head 15 in the Y-axis direction via the Y-axis rail 13. Drive. The Z-axis motor 43 drives the mounting head 16 of the working head 15 up and down, and the θ-axis motor 44 rotates the mounting head 16, that is, the nozzle 24 by 360 degrees.

  Although not shown in particular, each of the amplifiers is provided with an encoder, and the encoder value corresponding to the rotation of each motor (X-axis motor 41, Y-axis motor 42) is i / o by these encoders. This is input to the CPU 35 via the control unit 37. Thereby, the CPU 35 can recognize the front and rear, the left and right, the current position of the top and bottom, and the rotation angle of each mounting head 16.

  Further, a vacuum unit 45 is connected to the i / o control unit 37. The vacuum unit 45 is pneumatically connected to the nozzle 24 of the mounting head 16 via a vacuum tube 46. An air pressure sensor 47 is disposed in the vacuum tube 46. The vacuum unit 45 sucks the component 31 to the nozzle 24 by vacuum, or releases suction by vacuum release, air blow, and vacuum break (vacuum break).

  At this time, air pressure data in the vacuum tube 46 is output from the air pressure sensor 47 to the CPU 35 via the i / o control unit 37 as an electrical signal. As a result, the CPU 35 knows the state of the air pressure in the vacuum tube 46 and can recognize whether or not the component 31 is ready to be sucked by the nozzle 24 and the sucked component 31 is normally sucked. Can be recognized.

  Further, the i / o control unit 37 is connected to a positioning device, a belt drive motor, a substrate sensor, an abnormality display lamp, and the like via respective drivers. As described above, the positioning device is disposed below the substrate guide rail 7 in the base 6 of the electronic component mounting device 1 and positions the substrate 8 guided into the device. The belt drive motor circulates and drives the conveyor belt that is integrally disposed on the guide rail 7. The substrate sensor detects the loading and unloading of the substrate 8. The abnormality display lamp 3 (see FIG. 1 (a)) is lit or blinked when an abnormality occurs in the operation of the electronic component mounting apparatus 1 or the entry of a foreign object in the work area, thereby notifying the site worker of the occurrence of the abnormality.

  Further, the communication i / o interface 48, the operation input display device 5 and the recording device 49 shown in FIG. The communication i / o interface 48 is connected to these processing devices in a wired or wireless manner when, for example, teaching processing or the like is performed by another processing device such as a personal computer, so that communication with the CPU 35 is possible. To do.

  The recording device 49 can be mounted with various recording media such as a hard disk, MO, FD, CD-ROM / RW, flash memory device, etc., and the component mounting process of the electronic component mounting device 1 and the components performed in advance thereof Programs such as on-board teaching processing, various data such as parts library data and NC data from CAD are recorded and held, and these programs are loaded into the program area of the memory 39 by the CPU 35 to control each part. The data is also read into the data area of the memory 39 and subjected to a predetermined process. The data area of the memory 39 includes a number of subdivided register areas, and various count values are stored in the register area.

  In the operation input display device 5, when the component mounting operation is performed, the image processing unit 38 captures an image of the substrate 8 captured by the substrate recognition camera 22 (see FIG. 2) on the work head 15 side, and the image processing unit 38 also An image of the component 31 imaged by the component recognition camera 19 (see FIG. 1B) on the main device side is displayed on the display device. When the teaching process is executed, the teaching screen is displayed.

  In the above configuration, as described below, the electronic component mounting apparatus 1 uses the CPU 35 shown in FIG. 3 to count the cumulative usage period, the cumulative number of operations, and the cumulative operating distance of each component of the main unit, and calculate these totals. By comparing the numerical values with preset values for the guaranteed use period, the number of guaranteed operations, and the guaranteed operation distance, the maintenance management time for each component is notified in advance or the maintenance management time has come.

  FIG. 4 is a flowchart of a process for monitoring the operation of the actuator system and giving a warning and warning of maintenance management time. The actuator system includes a lifting / lowering device for positioning the substrate, a negative pressure flow path opening / closing mechanism for the vacuum unit 45, a tape feeding mechanism for the tape-type component supply device, a tray shelf lifting / lowering mechanism for the tray-type component supply device, a tray pulling mechanism, etc. It is.

  Further, the processing shown in the figure is performed every time the actuator system operates, and the preset notice use period and the number of notice operations are preset for each component of the actuator system registered in the recording device 49 in advance. The values of the guaranteed use period and the number of guaranteed operations are read out to the memory 39 and compared with the measured cumulative values.

  As shown in FIG. 4, the CPU 35 first increments the operation counter by “1” (S01). Note that this operation counter is provided in a predetermined storage area of the memory 39 for each component of the actuator system.

  Subsequently, the CPU 35 compares the value of the operation counter incremented by “1” with the number of guaranteed operations read from the memory 39, and determines whether or not the value of the operation counter exceeds the number of guaranteed operations (S02). ).

  The number of guaranteed operations described above is a limit value that can be guaranteed for the cumulative number of operations confirmed in advance by the durability test of the same member, and is a value set to warn that the maintenance management time for the actuator has come. is there.

  Therefore, when the value of the operation counter exceeds the guaranteed operation count in the above determination (S02 is YES), the CPU 35 indicates that the actuator has exceeded the guaranteed operation count and the maintenance management time has come. Alternatively, a warning is notified by the operation input display device 5 (S03).

  On the other hand, when the value of the operation counter does not exceed the guaranteed number of operations in the above determination (NO in S02), the CPU 35 subsequently determines whether or not the value of the operation counter exceeds the number of advance notification operations ( S04).

  The above-mentioned number of warning operations is the value obtained by subtracting the predetermined number of times from the guaranteed number of operations.When the value of the operation counter exceeds the number of warning operations, the number of days until the remaining number of operations will be calculated. This is for estimating the estimated number of days as a maintenance management period by estimating the value and the elapsed usage period.

  Therefore, when the value of the operation counter exceeds the number of advance notification operations in the above determination (S04 is YES), the CPU 35 uses the estimated number of days as a maintenance management time for the actuator or the operation input display device. 5 (S05), the process proceeds to step S06.

  In this case, for example, every time the actuator is operated, the remaining number of guaranteed operations is calculated by subtracting the value of the operation counter from the number of guaranteed operations, and how many days it takes to calculate the remaining number of guaranteed operations. It may be estimated from the value of the counter and the usage period that has passed and may be notified in advance.

  On the other hand, when the value of the operation counter does not exceed the number of times of the preliminary operation in the above determination (S04 is NO), the CPU 35 then determines whether or not the usage period of the actuator exceeds the warranty period ( S06).

  In general, machinery often manages the service life both by the number of operations for managing the service life resulting from wear and the use period for managing the service life resulting from fatigue over time. In this example, in consideration of the above-mentioned lifetime management system for machinery, the maintenance management time is determined by the warranty period in addition to the number of guaranteed operations as described above.

  Therefore, when the use period exceeds the guarantee period in the above determination (YES in S06), the CPU 35 determines that the use period of the actuator has exceeded the guarantee period and the maintenance management time has come. A warning is notified by the operation input display device 5 (S07).

  On the other hand, when the use period does not exceed the guarantee period in the above determination (NO in S06), the CPU 35 then determines whether or not the use period of the actuator exceeds the notice period (S08).

The above notice period is a value obtained by subtracting a predetermined period from the guarantee period. When the usage period exceeds the notice period, the remaining notice period is notified as a maintenance management period.
Therefore, when the use period exceeds the advance notice period in the above determination (YES in S08), the CPU 35 monitors that the use period of the actuator ends after the predetermined period and the maintenance management time comes. Alternatively, the operation input display device 5 gives a notice of advance notice (S09), and the notice / warning process for the maintenance management time of the actuator system is terminated.

On the other hand, when the use period does not exceed the guarantee period in the above determination (NO in S08), the CPU 35 immediately ends the advance notice / warning process for the maintenance management time of the actuator system.
FIG. 5 is a flowchart of a process for monitoring the operation of the XYZθ system and giving a warning and warning of maintenance management time. The XYZθ system includes a Y-axis rail 13 for driving the work head 15 in the XY direction, a ball screw for the X-axis rail 14, a lifting device for the mounting head 16, a pulley and a belt for rotating the mounting head 16, and its driving. The X-axis motor 41, the Y-axis motor 42, the Z-axis motor 43, the θ-axis motor 44, and the like that are sources.

  Further, the processing shown in the figure is performed every time the XYZθ system operates, and the preset notice use period and the notice operation distance for each component of the XYZθ system registered in the recording device 49 in advance. The values of the guaranteed use period and the guaranteed operating distance are read out to the memory 39 and compared with the measured cumulative values.

  As shown in FIG. 5, the CPU 35 first accumulates the operating distance (S101). The accumulated value of the operating distance is sequentially stored in a predetermined storage area of the memory 39 for each component of the XYZθ system.

  Subsequently, the CPU 35 compares the accumulated operating distance value with the guaranteed operating distance read from the memory 39, and determines whether or not the accumulated operating distance value exceeds the guaranteed operating distance (S102).

  The guaranteed operating distance is a limit value that can be guaranteed for the cumulative operating distance that has been confirmed in advance by the durability test of the same member, and is a value that is set to warn that the maintenance management time for the XYZθ system has come. It is.

  Therefore, when the cumulative operating distance value exceeds the guaranteed operating distance in the above determination (YES in S102), the CPU 35 monitors that the XYZθ system exceeds the guaranteed operating distance and the maintenance management time has come. A warning is notified by the device 2 or the operation input display device 5 (S103).

  On the other hand, when the cumulative operating distance value does not exceed the guaranteed operating distance in the above determination (S102: NO), the CPU 35 determines whether the cumulative operating distance value exceeds the advance operating distance. (S04).

  The above warning operating distance is the value obtained by subtracting the predetermined distance from the guaranteed operating distance.When the cumulative operating distance exceeds the warning operating distance, the cumulative number of days it will take to operate the remaining predetermined distance is accumulated. This is for estimating from the value of the operating distance and the elapsed use period, and to notify the estimated number of days as the maintenance management period.

  Accordingly, when the cumulative operating distance value exceeds the advance operating distance in the above determination (S104 is YES), the CPU 35 uses the estimated number of days as the maintenance management time of the XYZθ system for monitoring device 2 or operation input. A notice of advance notice is given by the display device 5 (S105), and the process proceeds to S106.

  On the other hand, if the cumulative operating distance does not exceed the advance operating distance in the above determination (S104 is NO), the CPU 35 then determines whether or not the XYZθ system usage period exceeds the warranty period. (S06).

  In this case as well, the maintenance period is monitored by monitoring the service life of the components of the drive mechanism both in the operating distance for managing the service life resulting from wear and in the service period for managing the service life resulting from fatigue over time. It is something to be determined.

  Therefore, when the use period exceeds the guarantee period in the above determination (YES in S106), the CPU 35 determines that the use period of the XYZθ system has exceeded the guarantee period and the maintenance management time has come. Alternatively, a warning is notified by the operation input display device 5 (S107).

  On the other hand, when the use period does not exceed the guarantee period in the above determination (NO in S106), the CPU 35 then determines whether or not the use period of the XYZθ system exceeds the notice period (S108). .

The above notice period is a value obtained by subtracting a predetermined period from the guarantee period. When the usage period exceeds the notice period, the remaining notice period is notified as a maintenance management period.
Therefore, when the use period exceeds the notice period in the above determination (YES in S108), the CPU 35 monitors that the use period of the XYZθ system ends after the predetermined period and the maintenance management time comes. 2 or the operation input display device 5 (S109), the XYZθ system maintenance management time notice / warning process is terminated.

On the other hand, if the use period does not exceed the guarantee period in the above determination (NO in S108), the CPU 35 immediately ends the notice / warning process of the maintenance management time of the XYZθ system.
As described above, according to the present invention, the actual accumulated use period, the accumulated use number, the accumulated use distance, etc. of each component are set in advance as the guaranteed use period, the guaranteed use number, the guaranteed use distance, the notice use period, By monitoring in comparison with the number of times of advance notice use, the use distance of advance notice, etc., it becomes possible to easily give notice of the maintenance management time of each component or warn that the maintenance management time has come.
