Description

  The present invention relates to a screen printing apparatus that performs various operations for manufacturing a mounting substrate, a coating apparatus (dispenser), an apparatus for performing capacity diagnosis and capacity recovery of a working machine such as a mounting apparatus.

  Conventionally, it is generally known that in a mounting apparatus for mounting an electronic component on a substrate to be processed such as a printed circuit board, the facility capacity is reduced due to aging of each part, etc., but such a state is left as it is. This is disadvantageous because it causes a gradual decline in productivity and product quality.

Therefore, it is desirable to maintain high productivity by objectively evaluating the current facility capacity and taking necessary measures (maintenance). For example, in Patent Document 1, as this type of equipment capacity diagnostic device, the operating time of a specific operating part of a mounting device is measured in advance, and this is stored as a fixed value. It has been proposed to evaluate and notify the current facility capacity based on the time difference by actually measuring it at a desired timing and comparing it with a fixed value. Therefore, it is conceivable to objectively evaluate the current facility capacity using such an apparatus.
JP 2003-17898 A

  However, since the apparatus of Patent Document 1 can only evaluate the current facility capacity, it has the following problems. In other words, there are many cases where the cause cannot be determined immediately even if the equipment capacity is evaluated to be low. In such a case, it takes time to identify the cause, and It was difficult to make smooth improvements. Therefore, from the field of production of mounted substrates, the equipment capacity evaluation apparatus as described above has not always been useful.

  The present invention has been made in view of such circumstances, and is not limited to diagnosing (evaluating) the equipment capacity. If the equipment capacity is reduced, the improvement is made more promptly and high production is achieved. The purpose is to maintain the sex.

In view of the above-described problems, the present invention is a capability diagnosis device for a working machine in a component mounting facility having one or more working machines for performing various operations for manufacturing a mounting board on which components are mounted, A measuring unit that measures an operation time of a specific operation specified in advance among operations performed on the work machine, and a determination unit that determines whether or not the specific operation satisfies a predetermined capability reduction condition based on the measurement result And an element specifying means for specifying one or a plurality of related elements from element parameters predetermined as elements correlated with fluctuations in the operation time of the specific operation when the measurement result satisfies the capability reduction condition; and a notifying means for notifying the diagnosis result the contents of the identified related components by the capacity reduction satisfying specific operation, and the element identification means, the determining means, the measuring The difference between the measurement result by the stage and the reference value is obtained, and the accumulated value of the difference corresponding to the preset number of productions of the substrate is obtained, and the ratio of the accumulated value to the reference tact time of the production number is a predetermined value. In the case of exceeding, it is determined that the capacity reduction condition is satisfied (Claim 1).

According to this apparatus, when a specific operation is performed on the work machine, the operation time is measured by the measurement unit, and based on the measurement result, it is determined by the determination unit whether or not the specific operation satisfies a predetermined capacity reduction condition. The When the operation capability is reduced, the element specifying unit specifies the related element correlated with the fluctuation in the operation time of the specific operation, and the specific operation and the content of the related element are notified as the diagnosis result by the notifying unit. Informed. In other words, when the capability of a specific action is reduced, the contents of the related element are notified in addition to the specific action. It becomes possible to narrow down.
Note that it is simple and reasonable to determine whether or not the capability of the specific operation is reduced by comparing the time required for the operation with the reference value. However, if the determination is made simply based on the time difference of one operation time, it is inconvenient that a specific operation with a very small time difference may be always determined to be normal (does not satisfy the capability reduction condition). In other words, even if the time difference of one operation time is very small, it may not be negligible in terms of tact time if the number of executions of the specific operation is large. In this case, the capability of the specific operation is reduced. Although it is appropriate to determine that a specific operation is accompanied by such a small error, it may be determined to be a normal operation. In this regard, in the capability diagnosis apparatus, the determination unit obtains a difference between the measurement result by the measurement unit and a reference value thereof, and obtains a cumulative value of the difference corresponding to a preset number of productions of the substrate. When the ratio of the cumulative value to the reference tact time of the first time exceeds the predetermined value, it is determined that the capacity reduction condition is satisfied. It is possible to make a reasonable decision, and the reliability of the diagnosis result is improved.
In addition, in the description of claim 1 (the same applies to claim 4), the “measurement result” means “mode value when the specific operation is performed the predetermined number of times in addition to the value for each specific operation. ”And“ average value ”in this case, the“ cumulative value ”in this case is“ mode value ”or a value obtained by multiplying the difference between the“ average value ”and the“ reference value ”by the predetermined number of executions. Become. The “reference tact time” means the time from the start of loading of a substrate to a predetermined work position of the work machine until the completion of unloading of the substrate after the work is completed.

  In each of the above devices, the storage means for storing the recovery information for recovering the ability of the specific action, and the information stored in the storage means based on the related element specified by the element specifying means It is preferable that recovery information specifying means for selecting recovery information to be selected is further provided, and the notification means further notifies the recovery information specified by the recovery information specifying means (claim 2).

  According to this configuration, when the operation capability of the specific operation is reduced, the recovery information is notified by the notification means together with the specific operation. For this reason, the operator does not need to examine the cause of the capacity reduction or improvement measures, and can take specific measures promptly based on the recovery information that is notified.

  In this case, an execution unit capable of executing a measure for recovering the operation capability of the specific operation, and the execution unit to recover the operation capability of the specific operation based on the recovery information specified by the recovery information specifying unit. It is preferable to further comprise means for controlling (Claim 3). According to this structure, the recovery | restoration measure of the operation capability is automated about a part or all of specific operation | movement.

On the other hand, another capability diagnosis apparatus according to the present invention is the capability diagnosis apparatus for a working machine in a component mounting facility having one or more work machines for performing various operations for manufacturing a mounting board on which components are mounted. And measuring means for measuring an operation time of a specific operation specified in advance among the operations carried out by the work implement, and determining whether the specific operation satisfies a predetermined capacity reduction condition based on the measurement result a judging means for, when the measurement result is the capacity reduction condition is satisfied, the elements for specifying one or a plurality of related elements from a predetermined element parameter as an element fluctuation correlation operation time of the specific operation Stored in the storage means on the basis of the specifying means, the storage means for storing the recovery information for recovering the operation capability of the specific action, and the related elements specified by the element specifying means Recovery information specifying means for selecting the corresponding recovery information from the information, execution means capable of executing measures for recovering the operation capability of the specific operation, and based on the recovery information specified by the recovery information specifying means Control means for controlling the execution means to restore the operation capability of the specific operation, and the determination means obtains a difference between a measurement result by the measurement means and a reference value thereof and produces a preset substrate. obtains a cumulative value of the difference of several minutes, the percentage of the cumulative value occupying the reference cycle time of the production number is shall be determined and the capacity reduction condition is satisfied when it exceeds a predetermined value (claim 4) .

  According to this apparatus, the action capacity recovery measure is automatically performed for the specific action without notifying the operator or the like by the notice means as described above.

In addition, when monitoring a plurality of specific operations, there may be a case where a plurality of operation capacities are simultaneously reduced, but in that case, it is determined which operation should be prioritized for improvement. It can be difficult. Such a problem is solved by the following configuration. That is, the measuring unit measures the operation time of a plurality of types of specific operations as the specific operation, and the determination unit determines whether or not each specific operation satisfies the capability deterioration condition (Claim 5 ). . In the case where the notifying means is provided, the notifying means outputs the diagnosis result so that the degree of the influence of each specific action on the tact time can be determined when a plurality of specific actions satisfy the capability reduction condition. Notification is made (claim 6 ).

  According to this configuration, since it is possible to determine the degree of influence on the tact time among a plurality of specific actions whose operating ability is reduced, by carrying out ability recovery measures (maintenance) in descending order of the degree of influence, It becomes possible to proceed with the work efficiently.

In addition, there is not necessarily one related element correlated with the operation time of one specific operation, and there may be a plurality of related elements. In this case, any related element may be included in the fluctuation of the operation time of the specific operation. It is more convenient to be able to identify what is most relevant. Therefore, in the above apparatus, when the measuring unit that measures the time of the specific operation is the first measuring unit, a second measuring unit that measures the amount of change of each related element of the element parameter is further provided. Preferably, the element specifying means specifies one or a plurality of related elements based on a difference between a measurement result obtained by the second measuring means and a reference value thereof (Claim 7 ).

  According to this configuration, even when there are a plurality of related elements for one specific operation, it is possible to specify and notify which element is related to the fluctuation of the operation time of the specific operation. .

On the other hand, still another capability diagnosis device according to the present invention is a capability diagnosis device for a working machine in a component mounting facility having one or more work machines for performing various operations for manufacturing a mounting board on which components are mounted. The first measuring means for measuring the operation time of the specific operation specified in advance among the operations performed by the work machine, and whether or not the specific operation satisfies a predetermined capacity reduction condition based on the measurement result And a determination means for determining whether or not one or a plurality of related elements are specified from element parameters predetermined as elements correlated with fluctuations in the operation time of the specific operation when the measurement result satisfies the capability reduction condition Specified by the element specifying means, the second measuring means for measuring the amount of change of each related element of the element parameter, the specific action satisfying the capability reduction condition, and the element specifying means An informing means for informing the contents of the related element as a diagnosis result, wherein the element specifying means outputs a predetermined number of the related elements in descending order of the difference between the measurement result by the second measuring means and the reference value. It is specified from the parameters (claim 8).
Even in this configuration, when the capability of the specific operation is reduced, the contents of the related element are notified in addition to the specific operation, so the operator can use the contents of the related element as a clue. It becomes possible to narrow down causes and improvement measures. In particular, since the element specifying means can specify only elements that are particularly strongly related to the reduction in the capability of the specific operation, the convenience in narrowing down causes and improvement measures is improved.
In the capability diagnosis apparatus as described above, the working machine has, for example, a movable component suction head, and the head picks up a component from a predetermined component supply unit and mounts it on the mounting substrate. There is a mounting device, and in this case, the measuring unit measures the operation time by using one or more operations specified in advance among the operations during the mounting work in the mounting device as the specific operation. ). In this case, as the specific operation, a component suction / mounting operation by the head, a camera recognition of the mounted substrate, a camera recognition of the component sucked by the head, a loading / unloading of the mounted substrate, and the like can be considered.

  According to the capability diagnosis apparatus of the first aspect of the present invention, when the capability of the specific operation of the work machine is reduced, one or more related elements correlated with the operation in addition to the content of the specific operation Therefore, the operator can narrow down the cause of the capacity reduction and improvement measures by using the related element as a clue. Therefore, it is possible to easily and quickly devise and cope with an improvement measure for restoring the capability of the specific operation. In particular, according to the configuration according to claim 2, since the specific improvement measures (recovery information) are notified together, the operator does not need to examine the cause and the improvement measures himself, and promptly follows the notified recovery information. It becomes possible to cope with. Therefore, even when the facility capacity is lowered, the improvement can be promptly achieved and high productivity can be maintained.

  A preferred embodiment of the present invention will be described with reference to the drawings.

Is abbreviated to a predetermined mounting work position (position shown in FIG. 1), and is lifted up from the conveyor 2 and clamped by a clamp mechanism (not shown). Note that both sides of the mounting operation position (both sides in the transport direction) are standby positions for the substrate P so that the substrate P before and after the mounting operation can temporarily wait.

  Although not shown in the drawings, each conveyor 2 incorporates a tension sensor that detects belt tension and a motor-driven belt tensioner that adjusts the tension, and the belt tensioner is appropriately driven according to the sensor output value. As a result, the belt tension can be kept constant.

  In the following description, for convenience of explanation, the conveying direction of the conveyor 2 is described as the X-axis direction, the direction perpendicular to the Y-axis direction on the horizontal plane is defined as the Y-axis direction, and the direction orthogonal to the X-axis and Y-axis is defined as the Z-axis direction. I will proceed.

  On both sides of the conveyor 2, component supply units 4 and 5 that supply mounted components are provided. Among these component supply units 4 and 5, the component supply unit 4 located on the front side of the mounting apparatus has a plurality of rows of tape feeders 4a arranged in the X-axis direction. A small chip-shaped chip component such as a capacitor is supplied to a predetermined component supply position facing the mounting operation position.

  On the other hand, a tray feeder 5a is disposed in the component supply unit 5 located on the rear side of the mounting apparatus. The tray feeder 5a has a magazine rack in which trays T, in which large-sized parts such as QFP and BGA, packaged electronic parts or mounted connectors are stored in a matrix, and a tray T that is drawn out from the magazine rack. And a mechanism for supplying the large component by pulling out a predetermined tray T to a component supply position on the side of the conveyor.

  A head unit 6 for component mounting is provided above the base 1.

  The head unit 6 is configured to be movable in the X-axis direction and the Y-axis direction within a certain area so that components can be held from the component supply units 4 and 5 and mounted on the substrate P. That is, the support member 11 of the head unit 6 is movably mounted on the rail 7 in the Y-axis direction on the base 1, and the head unit 6 is mounted on the support member 11 and the guide member 14 in the X-axis direction. It is mounted so as to be movable. A support member 11 is screwed and attached to a ball screw (not shown) driven by the Y-axis servo motor 9, whereby the support member 11 is moved in the Y-axis direction and driven by the X-axis servo motor 15. The head unit 6 is screwed to the ball screw 13 to be moved, whereby the head unit 6 is moved in the X-axis direction.

  The head unit 6 is mounted with a plurality of mounting heads 20 for picking up components and mounting them on the substrate P. In this embodiment, four mounting heads 20 (necessary) configured in a shaft shape are mounted. The first to fourth heads 20a to 20b are appropriately mounted in a row in the X-axis direction.

  These mounting heads 20 are connected to a lifting mechanism using a Z-axis servomotor 22 (see FIG. 3) as a drive source and connected to a rotation mechanism using an R-axis servomotor 24 (see FIG. 3) as a drive source. These mechanisms are driven in the vertical direction (Z-axis direction) and around the axis (R-axis direction) with respect to the head unit 6, respectively.

  A nozzle member 21 for component suction is provided at the tip of each mounting head 20. Each nozzle member 21 is connected to a negative pressure supply device via a valve or the like (not shown), and negative pressure is supplied to the tip of the nozzle member 21 when the components are taken out from the feeders 4a and 5a. Thus, the components are sucked.

  Although not shown, a negative pressure valve that opens and closes the passage, a negative pressure valve sensor that detects an operating state of the negative pressure valve, and a negative pressure passage are provided in the negative pressure passage that extends from the nozzle tip of each mounting head 20 to the negative pressure supply device. Are provided with a plurality of pressure (negative pressure) sensors for detecting the pressure at a specific position, a flow rate sensor for detecting the intake flow rate in the passage, and the like. In addition, an air (positive pressure) supply passage connected to an air supply device is joined to a middle portion of each negative pressure passage, and a positive pressure valve or the like for opening and closing the passage is disposed. At the time of component mounting or maintenance, the negative pressure valve is closed and the positive pressure valve is opened, so that air is introduced into the negative pressure passage and discharged from the nozzle tip.

  The head unit 6 is further provided with a substrate recognition camera 25 for recognizing the position of the substrate P. The substrate recognition camera 25 has a camera body 25a having a CCD area sensor and the like, and an illumination device 25b (see FIG. 3), and the imaging direction is downward so that various marks on the substrate P can be imaged. It is attached to the head unit 6 so as to be oriented.

  On the other hand, on the base 1, component recognition cameras 17 for recognizing components attracted by the mounting heads 20 of the head unit 6 are arranged in the component supply units 4 and 5. This component recognition camera 17 has a camera body 17a having a CCD linear sensor and the like, and an illumination device 17b (see FIG. 3), and takes an image so that the suction component by each mounting head 20 can be taken from below. Each is arranged in a state where the direction is directed upward. In other words, after the component suction, the head unit 6 moves above the component recognition camera 17 along a predetermined path, so that each suction component is imaged from the lower side along with the movement.

  FIG. 3 is a block diagram schematically showing the configuration of a controller that comprehensively controls component mounting operations by the mounting apparatus.

  In this figure, a controller 30 includes a main control means 32 constituted by a CPU, a mounting program storage means 33 for storing a mounting program, a data storage means 34 for storing various data for component mounting, and a head. Motor control means 35 for controlling the X-axis, Y-axis, Z-axis, and R-axis motors 9, 15, 22, 24, etc. for driving the unit 6 and the nozzle member 20, external input / output means 36, and image processing means 37 etc.

  The motor control means 35 controls the motors 9, 15, 22, 24 based on signals from encoders provided to the motors 9, 15, 22, 24 and a target value given from the main control means 32. Is what you do. Although not shown, the motor control means 35 also controls the motor and the like for driving the conveyor 2.

  The data storage means 34 stores various data necessary for processing such as component mounting and ability diagnosis described later.

  The external input / output means 36 includes, as input elements, a post-board detection sensor for detecting loading / unloading of the printed board P with respect to the mounting work position, various sensors disposed in the negative pressure passages of the nozzle members 21, and conveyors. While various sensors 39 such as the tension sensor 2 are connected, the lighting devices 17b and 25b of the cameras 17 and 25 and the belt tensioners of the conveyors 2 are connected as output elements.

  A component recognition camera 17 and a board recognition camera 25 are connected to the image processing means 37, and image signals from these cameras 17 and 25 are taken into the image processing means 37 and subjected to predetermined image processing. Thus, the image data is sent to the main control means 32.

  The main control means 32 controls the motors 9, 15, 22, 24 and the like for the operation of the conveyor 2, the head unit 6 and the nozzle member 20 through the motor control means 35 and the cameras 17, Control of the 25 lighting devices 17b and 25b, control of the belt tensioner of the conveyor 2, and the like are performed via the external input / output means 36.

  Further, the main control means 32 performs processing for diagnosing equipment capacity and restoring equipment capacity during the mounting operation according to the flowcharts of FIGS. This process is a predetermined process that is selected in advance as having a great influence on the tact time among various operations such as the component adsorption operation of the mounting head 20 performed during a series of component mounting operations on a single substrate P. With respect to the operation (hereinafter referred to as a specific operation), whether or not the capability of the specific operation is degraded is diagnosed based on the operation time, and the specific operation is diagnosed as the capability is degraded. This is a process of notifying the operator of necessary measures (capability recovery measures) for recovering the ability of the user through the display unit 38 such as a liquid crystal display device and recovering itself (self-recovery) if possible.

  In the present embodiment, the main control means 32 and various sensors 39 and the like function as first and second measurement means according to the present invention, and the main control means 32 determines the determination means, the element specifying means, and the recovery information. The data storage unit 34 functions as a specifying unit, the data storage unit 34 functions as a storage unit according to the present invention, and the main control unit 32 and the display unit 38 function as a notification unit according to the present invention.

  Next, processing for diagnosis and recovery of facility capacity based on the control of the controller 30 will be described with reference to FIGS. 4 and 5 and with reference to flowcharts of FIGS.

  FIG. 4A and FIG. 5B show a list used in equipment capacity diagnosis and recovery processing, and FIG. 4A shows a specific operation that is a target of capacity diagnosis. FIG. 5A shows an “operation time element list” in which elements particularly correlated with fluctuations in the operation time of a specific operation are registered. These lists are incorporated in the implementation program in advance.

  The operation list includes columns of “operation No.”, “operation name”, “number of operations”, “operation time”, “reference time”, “time difference”, and “total operation time difference”.

  In the list, “operation name” is a name of a specific operation, and the correspondence between “operation No” and “operation name” is set in advance. The “number of operations” is the number of executions of a specific operation during the production of one board, and is registered in advance based on the mounting program. The “operation time” is a measurement value of the operation time of a specific operation, and in this embodiment, the mode value during the production of one board is recorded. The “reference time” is a value that serves as a criterion for determining the capability of a specific operation. For example, a design value or a value at the time of initial operation of the mounting apparatus is registered in advance. “Time difference” is an absolute value of a difference between “operation time” and “reference time”, and “total operation time difference” is a value obtained by multiplying “time difference” by “number of operations”. In the present embodiment, the “operation time” is the mode value during the production of one substrate as described above, but may be an average value.

  On the other hand, the operation time element list includes columns of “operation No.”, “element No.”, “element name”, “reference value”, and “measurement value”.

  “Operation No” in this list corresponds to “Operation No” in the operation list, and for each “Operation No”, one or a plurality of correlation factors are correlated with the related elements, that is, the time variation of the specific operation related to the No. Elements are registered in advance (corresponding to element parameters according to the present invention). “Reference value” is the reference value of the related element. This “reference value” is a criterion for specifying an element that is particularly related to fluctuations in the operating time of a specific operation among related elements. For example, a design value or a value at the time of initial operation of a mounting apparatus is used. It is registered as “100”. The “measurement value” is a measurement value of a related element, and in this embodiment, the mode value during the production of one board is recorded as a value when the reference value is “100”. Yes. This value may be an average value during the production of one substrate.

  The equipment capability diagnosis process includes an actual recording process for actually measuring the “operation time” of the specific operation registered in the operation list and the related elements registered in the operation time element list during the mounting operation, and this actual recording. It consists of a capability diagnosis process for performing a specific capability diagnosis from the processing result. In the following description, for convenience of explanation, a case where processing such as capability diagnosis is performed only for a specific operation explicitly described in the operation list of FIG.

<Measurement record processing>
6 and 7 are flowcharts showing the actual measurement recording process. This process is performed at a predetermined timing with a preset number of production of substrates P, for example, one substrate or production lot as one unit. In the present embodiment, a case where a single substrate is used will be described as an example.

  When this process is started, the main control means 32 first initializes the field of the actual measurement value recorded in each list (reset to the states shown in FIGS. 4A and 5A; step S2). ).

  Next, the conveyor 2 is driven to start conveyance (carrying-in) of the substrate P in the standby position, and it is determined whether or not this carry-in operation is registered in the operation list. Measurement of the time required for measurement and measurement of related elements registered in the operation time element list (steps S4 to S8). The time measurement is performed using a system clock used by the main control means 32.

  In the example of FIG. 4A, since the substrate loading operation is registered in the operation list (operation No. 006), the main control unit 32 measures the time required for the loading operation of the substrate P. Specifically, the time from when the board detection sensor arranged at the standby position switches to the non-detection state as the board P is conveyed until the board detection sensor arranged at the mounting work position detects the board is measured. And remember. Further, the related elements registered in the operation time element list as the related elements of the operation No. 006, that is, the operating current value of the substrate detection sensor and the tension value of the tension sensor are measured and stored. Here, the operating current value of the substrate detection sensor is measured by an ammeter incorporated on the control substrate of the sensor.

  It should be noted that the measurement value of the operation time and the measurement value of the related element measured in step S8 are individually stored for each operation No. and element No. each time a later-described ability diagnosis process is executed (step S16 described later). , S24, S32, S42).

  As described above, the operation current value of the substrate detection sensor and the tension value of the tension sensor are registered as the related elements of the carry-in operation (operation No. 006) of the substrate P because the failure of the substrate detection sensor or the slack of the conveyor belt. This is because there is a high possibility that the operation time of the substrate carry-in operation varies.

  When the board P is carried into the mounting work position (YES in step S10), the main control means 32 moves the head unit 6 to the component supply units 4 and 5, and this component suction operation is included in the operation list as a specific operation. It is determined whether it is registered. If it is registered, the time required for the suction operation and the measurement of related elements are performed (steps S12 to S16).

  In the example of FIG. 4A, the suction operation of each of the first to fourth heads 20a to 20b is registered in the operation list (operation No. 001 to 004). The time required for the adsorption operation is measured.

  Specifically, the time from when the mounting head 20 reaches a predetermined height position for component suction until the pressure in the negative pressure passage reaches a predetermined value set in advance is measured and stored. Also, related elements registered in the operation time element list as related elements of operation Nos. 001 to 004, that is, a source pressure value in the negative pressure passage (pressure value in the vicinity of the negative pressure supply device), a flow value of the negative pressure passage The operating current values of the pressure (negative pressure) sensor and the negative pressure valve sensor are measured and stored.

  As described above, the pressure value in the negative pressure passage, the flow rate value, and the operating current value of each sensor are registered as the related elements of the component suction operation (operation No. 001 to 004). This is because there is a high possibility that the operation time of the component adsorption operation will fluctuate due to clogging of the components, failure of the negative pressure supply device and sensors.

  When the component suction is completed (YES in step S18), the main control means 32 starts a predetermined component recognition operation for imaging and recognizing each suction component by the component recognition camera 17, and the component suction operation is specified. It is determined whether the operation is registered in the operation list. If the operation is registered, the time required for the component recognition operation and the related elements are measured (steps S20 to S24).

  In the example of FIG. 4A, since the component recognition operation is registered in the operation list (operation No. 005), the main control unit 32 measures the time required for component recognition. Specifically, the head control unit 32 passes through the component recognition camera 17 from the time when the head unit 6 is set at a predetermined recognition start position on the upper side (X-axis direction side) of the component recognition camera 17. The time until the component recognition process is completed is measured and stored. Further, as a related element of the operation No. 005, the luminance value of the lighting device 17b is measured and stored. In this embodiment, the luminance of the illumination device 17b is obtained as an average gradation value (average value of gradations of each pixel) of the component image acquired by the component recognition operation. A luminance sensor may be provided at 17b to directly measure the luminance.

  The reason why the luminance of the illumination device 17b is registered as a related element of the component recognition operation (operation No. 005) in this way is highly likely to change the component recognition time depending on the brightness and contrast of the image. This is because there is a close relationship with light and darkness and contrast.

  When the recognition of the component is completed (YES in step S26), the main control means 32 moves the head unit 6 to the mounting work position and mounts (mounts) the suction component on the board P, and specifies this component mounting operation. It is determined whether it is registered in the operation list as an operation. If it is registered, the time required for the adsorption operation and the measurement of related elements are performed (steps S28 to S32). In the example of FIG. 4A, since the component mounting operation is not registered, NO is determined in step S30 in this case.

  When the mounting of the components is completed (step S34), the main control means 32 determines whether or not all the components are mounted on the board P. If not, the process returns to step S12 and remains. Move to the mounting operation of the parts. On the other hand, if completed, the main control means 32 releases the clamp of the substrate P and then drives the conveyor 2 to start transporting (unloading) the substrate P, and this unloading operation is included in the operation list. It is determined whether it is registered. If it is registered, the time required for the carrying-out operation and measurement of related elements are performed (steps S38 to S42).

  In the example of FIG. 4A, since the substrate unloading operation is registered in the operation list (operation No. 007), the main control unit 32 measures the time required for the unloading operation of the substrate P. Specifically, the time from when the substrate detection sensor at the mounting work position is switched from the detection state to the non-detection state until the substrate detection sensor at the carry-out side standby position detects the substrate is measured and stored. In addition, as the related elements of the operation No. 007, the operating current value of each substrate detection sensor and the tension value of the tension sensor are measured and stored. Thus, the actual measurement recording process ends.

  As described above, the operation current value of the substrate detection sensor and the tension value of the tension sensor are registered as related elements of the substrate P unloading operation, as in the case of the substrate loading operation. This is because the operation time of the substrate unloading operation is likely to fluctuate due to the slack.

  6 and 7 are examples in the case where the actual recording process is performed for the production of a single substrate P. When the actual recording process is performed for the production of a plurality of substrates P, steps S4 to S42 are performed. This process is looped by the number of sheets produced.

<Performance diagnosis process>
FIG. 8 is a flowchart showing the capability diagnosis process. This process is executed after the end of the above-described actual recording process.

  When this process is started, the main control means 32 records the measurement results stored in the respective processes of steps S8, S16, S24, S32, and S42 of FIG. 6 in each list (step S50). Specifically, regarding the operation list, the mode value of the operation time of each specific operation, that is, the mode of a plurality of measurement values individually stored every time the specific operation (operation No) is performed. The value is obtained and recorded in the “operation time” of the list, and the “total operation time difference” is calculated and the result is recorded in the list. The “total operation time difference” is obtained by multiplying the absolute value of the difference between the “operation time” and the “reference time” by the “number of operations” as described above. Thereby, for example, an operation list as shown in FIG. 4B is created.

  On the other hand, with respect to the operation time element list, the main control means 32 has a plurality of modes that are measured and stored individually every time the specific operation is performed as a related element, that is, a mode value of measurement values of each related element. The mode value of the measured values is obtained and recorded in “Measured value” in the same list. Thereby, for example, an operation time element list as shown in FIG. 5B is created.

  Next, the main control means 32 determines whether or not there are those that satisfy a predetermined capacity reduction condition for each specific action registered in the action list, specifically, whether or not there is one that satisfies the following expression: (Step S52).

[Equation 1]
(Total operating time difference / Total mounting time) x 100> or = 2%
That is, the accumulated value of the error (absolute value) between the actual “operation time” and its “reference time” (“total operation time difference”) is the tact time (total mounting time; in this embodiment, board loading is started). If it takes 2% or more of the time from the mounting operation to the completion of board unloading), the specific operation has a significant impact on the tact time, and the specific operation has a reduced ability. Diagnose that Note that the reference value (2%) of the capability reduction condition is an eigenvalue set according to the specifications of the mounting apparatus and is not particularly limited in the present invention.

  The main control means 32 specifies the specific operation when there is a condition that satisfies the capacity reduction condition during the specific operation (YES in step S52), and further correlates with the specific operation based on the operation time element list. A certain related element is specified (steps S54 and S56).

  For this specification, a related element registered in the operation time element list having a large difference between the “measured value” and the “reference value”, for example, a value having a difference value of a predetermined value (10 points) or more is selected. By doing. In this case, when a plurality of elements are registered as related elements and there are a plurality of differences between the “measured value” and the “reference value” that are larger than a predetermined value, the main control means 32 Identify all relevant elements. In this case, for example, a predetermined number of related elements may be specified in descending order of difference between the “measured value” and the “reference value”.

  When the above processing is completed, the main control means 32 records the above diagnostic result on a diagnostic result sheet stored in advance. In other words, the specific action determined to satisfy the capacity reduction condition in the process of step S54 and the related element specified in the process of step S56 are recorded on the diagnosis result sheet, and the contents of each list related to the specific action and the related element Etc. are recorded on the same sheet. As a result, the capability diagnosis process is terminated.

  As a specific example, for example, when an actual recording result as shown in FIGS. 4B and 5B is obtained in the operation of total mounting time = 80 s, as shown in FIG. Therefore, the component suction operation (operation No. 002) of the second head 20b satisfies the capability reduction condition of Equation 1 (1.96 / 80 × 100 = 2.45%> 2%). Of the related elements registered in the operation No. 002 of the operation time element list, those having a difference between the “measured value” and the “reference value” of 10 points or more are in the negative pressure passage of the second head 20b. It is a flow rate value (element No. 002). Therefore, in this case, the main control means 32 records the operation No. 002 and the related element No. 002 on the diagnosis result sheet and records the list contents regarding the No on the same sheet in the above-described capability diagnosis processing. .

  If the main control means 32 determines that there is no specific action that satisfies the ability reduction condition in the action list (NO in step S52), the main control means 32 performs the ability diagnosis process without recording it in the diagnosis result sheet. finish.

<Capability recovery process>
FIG. 9 is a flowchart showing the ability recovery process. This process is executed after the above-described capability diagnosis process, for example, during a mounting operation on the subsequent substrate P, or at an arbitrary time designated by the operator.

  In this process, first, the main control means 32 reads the diagnosis result sheet and determines whether or not the diagnosis result is recorded on the sheet (step S60). If there is no diagnosis record, the main control means 32 controls the display unit 38 to display that there is no abnormality for each specific action registered in the action list (step S80), and this ability recovery process Exit.

  On the other hand, when there is a diagnosis result in the diagnosis result sheet, the main control means 32 restores the recovery information corresponding to the related element No. from the element information database (element information DB) based on the related element No. recorded in the diagnosis result. That is, various information necessary for returning the “measured value” of the related element to the “reference value” is read (step S62).

  This element information DB includes “measured values” of related elements such as whether self (automatic) recovery is possible, the necessity of parts replacement, the type of replacement parts (part No), operation procedures such as part replacement and adjustment, and images thereof. Are stored in advance in the data storage means 34. The information storage means 34 stores the information stored in the data storage means 34 in advance.

  Next, the main control means 32 determines whether there is an item that can be self-recovered based on the recovery information read from the element information DB, that is, whether there is a capability recovery measure that can be performed by itself without the operator's involvement (step S64). If there is an item that can be self-recovered, the main control means 32 further determines whether or not to execute self-recovery processing (step S66).

  This determination is left to the operator, for example, by displaying on the display unit 38 that there is a self-recoverable item. That is, the main control means 32 executes the self-recovery process when the operator inputs the permission to permit the self-recovery process (step S68), and otherwise executes the self-recovery process. Then, the process proceeds to step S78.

  When the self-recovery process is executed, the main control unit 32 and the effect of the self-recovery process are verified (step S70). Specifically, in the mounting work currently in progress, the actual measurement recording process is executed for the specific operation related to the operation No. recorded in the diagnosis result sheet, and the capability reduction condition (the above formula 1) is performed according to the capability diagnosis processing. It is determined whether or not the above is satisfied. As a result, when it is determined that self-healing has been achieved, that is, when the capability reduction condition is not satisfied, the main control means 32 deletes the diagnosis result related to the operation No from the diagnosis result sheet and returns to step S60. (Step S72). On the other hand, if it is determined that self-recovery has not occurred, the process proceeds to step S78 described later.

  On the other hand, if it is determined in step S64 that there is no self-recoverable item, the main control means 32 determines whether there is an item that requires component replacement (step S74). The process proceeds to step S78. On the other hand, if it is determined that there is a corresponding item, the component information related to the component No. is read from the component information database (component information DB) based on the component type (component No.) read from the element information DB in step S62. (Step S76). The component information DB is composed of various information relating to various components constituting the mounting apparatus, such as component name, component model, component image data, inventory quantity, storage location, and the like, and is stored in the data storage unit 34 in advance. Has been.

  Next, the main control means 32 controls the display unit 38 to display the recovery information read from the element information DB together with the contents of the diagnosis result sheet (step S78). At this time, when passing through steps S74 and S76, the main control means 32 further displays component information in addition to these pieces of information (step S78). This completes the ability recovery process.

  As a specific example, for example, when an actual recording result as shown in FIGS. 4B and 5B is obtained, operation No. 002 (component suction operation by the second head 20a) is displayed on the diagnosis result sheet. When the related element No. 002 (the flow rate of the negative pressure passage of the second mounting head 20b) is recorded, the main control means 32 reads the recovery information corresponding to the related element No. 002 (step S62). As recovery information corresponding to the related element No. 002, for example, information “air cleaning” and “disassembly cleaning” is stored in the element information DB, and the recovery information is read out. Here, “air cleaning” is a measure for introducing air (positive pressure) into the negative pressure passage for a certain period of time. In this case, the main control means 32 determines that self-recovery is possible, and permits the operator. Based on the input, “air cleaning” is executed (steps S64 to S68). Specifically, the positive pressure valve of the air passage corresponding to the second head 20b is opened and air is discharged from the nozzle tip while supplying air to the negative pressure passage for a certain time. That is, in this example, the positive pressure valve or the like of the air passage corresponding to the second head 20b corresponds to the execution means according to the present invention (execution means capable of executing a measure for restoring the operation capability of the specific operation), The main control means 32 corresponds to a means for controlling the execution means.

  Then, after executing “air cleaning”, the main control means 32 verifies the effect of the self-recovery processing, and the ability of the specific operation (part suction operation by the second head 20a) related to the operation No. 002 is recovered. If it is determined that there is, the diagnosis result relating to the operation No. 002 is deleted from the diagnosis result sheet (steps S70 and S72). On the other hand, if not recovered, the main control means 32 displays “air cleaning” and “disassembly cleaning” on the display unit 38 as the recovery information and notifies the operator (step S78). In this case, the operator repeatedly performs “air cleaning” by manual operation, or restores the specific operation (part suction operation by the second head 20a) related to operation No. 002 by performing “disassembly cleaning”. Is possible. In particular, for “disassembly cleaning”, the procedure and the like are displayed on the display unit 38, and this allows the operator to disassemble the mounting head 20 smoothly and perform cleaning.

  As described above, this mounting apparatus measures the operation time of a specific operation that affects the tact time among various operations such as a component suction operation executed in the component mounting operation, and specifies the specific operation based on the operation time. A configuration for diagnosing whether or not the performance of the operation is reduced and, when the capability is reduced, for notifying the operator of recovery information for recovering the capability of the specific operation via the display unit 38 It has become. For this reason, even if the capability of the specific operation of the mounting apparatus is reduced, the operator does not have to examine the cause or improvement measures by himself, but by taking specific measures according to the recovery information displayed on the display unit 38. It becomes possible to respond promptly. Therefore, even when the equipment capacity (operating capacity) of the mounting apparatus is reduced, the improvement can be promptly achieved and high productivity can be maintained.

  In particular, in this mounting apparatus, items that can be self-recovered among items included in the recovery information are subjected to self-recovery processing based on the control of the main control means 32, and the effect is automatically verified. 9 (steps S66 to S70 in FIG. 9), that is, part (or all) of measures for improving the facility capacity (operation capacity) is automated, so that it can be performed quickly and reliably. The facility capacity can be improved and the maintenance burden on the operator can be reduced.

  In addition, in this mounting apparatus, the value of the related element that correlates with the fluctuation of the operation time of the specific operation is measured, and when specifying the recovery information, the recovery information is specified based on this related element. Therefore, there is an advantage that reliable recovery information can be provided promptly. In other words, the factor of fluctuation in the operation time of the specific operation is not necessarily one, and there are a plurality of factors, and it is not easy to specify the countermeasure accurately. However, after measuring the value of the related element that correlates with the fluctuation of the operation time of the specific action, and investigating the related element that has a large influence on the fluctuation of the operation time of the specific action from the measured value, According to the configuration of the above-described embodiment in which the recovery information is specified from the element information DB, the number of determination elements is increased by examining the state of the related element, and the recovery information can be narrowed down accurately and promptly. Therefore, highly reliable recovery information can be provided promptly.

  In the capacity diagnosis process, the difference between the “operation time” of the specific action and its “reference time” is multiplied by the “number of movements” to obtain a “total operation time difference”. Since the ability of the specific operation is diagnosed depending on whether the condition is satisfied, there is also an effect that an appropriate diagnosis can be performed from the viewpoint of tact time. That is, when diagnosing whether or not the capability of a specific operation is reduced, it is simple and reasonable to compare the “operation time” required for the operation with the “reference time”. In this case, it is possible to simply determine the time difference of one “operation time”. However, in this case, a specific operation with a very small time difference may be always determined as a normal operation. It is. In other words, even if the time difference of one “operation time” is very small, it may not be negligible in terms of tact time if the number of operations of the specific operation is very large. Although it is appropriate to determine that it has decreased, there is a possibility that a specific operation with such a small error may be determined as a normal operation. However, according to the mounting apparatus described above, the “total operation time difference” taking into account the “number of operations” is obtained, and the ability of the specific operation is diagnosed based on this “total operation time difference”. And a highly reliable diagnosis result can be obtained.

  Regarding this mounting apparatus, when a plurality of specific operations are registered in the diagnosis result sheet when the diagnosis result is displayed on the display unit 38 in the ability recovery process (step S78 in FIG. 9), for example, tact time The diagnosis results are displayed on the display unit 38 in such a manner that the degree of the influence on the tact time can be easily recognized, such as displaying in descending order of the influence on the tact time. May be.

  According to this configuration, the operator can easily specify the priority order of maintenance (capability recovery measures). For example, when the maintenance time is limited, the priority is given to the one having the greatest effect on the tact time. Maintenance can be carried out efficiently and rationally by carrying out maintenance.

  The same applies to the case where a plurality of related elements are specified for one specific operation registered in the diagnosis result sheet. In this case, the “reference value” and “ You may make it display a related element in order from a thing with a big difference with a "measurement value".

  According to this configuration, priority is selected from the related elements that have a strong relationship with the specific action, so it is effective in identifying the cause of capacity reduction, and this also contributes to the efficiency of maintenance work. Will be.

  The mounting apparatus described above is an example of a preferred embodiment of the mounting apparatus to which the capability diagnosis apparatus according to the present invention is applied, and the specific configuration thereof can be appropriately changed without departing from the gist of the present invention. It is. For example, the contents of the action list and the action time element list shown in FIGS. 4 and 5 are merely examples for explaining the present invention, and are not limited to the contents.

  In addition, in the present embodiment, the “total operation time difference” that is the basis for determining the capability of a specific operation is the mode value (or average value) of the operation time of a specific operation performed per substrate as described above. The operation time is a value obtained by multiplying the “time difference” between the “operation time” and the “reference time” by the “number of operations”. Of course, each time a specific operation is performed per substrate, “ The “time difference” between the “operation time” and the “reference time” may be obtained, and the accumulated value may be set as the “total operation time difference”.

  In the above embodiment, the capability diagnosis processing and the capability recovery processing are performed based on the actual recording processing during the production of one substrate P. Of course, the actual recording during the production of a plurality of substrates P is performed. A capability diagnosis process may be performed based on the process.

  In the above-described embodiment, regarding the capacity diagnosis process (Equation 1), the “total operation time difference” is obtained by multiplying the absolute value of the difference between the “operation time” and the “reference time” by the “number of operations” as described above. However, the difference between the “operation time” and the “reference time” may be obtained in consideration of positive and negative, and the “total operation time difference” may be obtained by multiplying the time difference by the “number of operations”. That is, in the above embodiment, the capability diagnosis is performed from the viewpoint of how much the error in the operation time of the specific operation affects the tact time (target value) regardless of the reduction of the tact time and the delay. The capability diagnosis may be performed in consideration of whether the error of the operation time affects the direction of shortening or delaying the tact time. For example, if the difference between the “operation time” and the “reference time” is always a negative value, it is advantageous in terms of tact time, but cooperation with other obstacles, for example, other operations related to a specific operation In this case, whether the error in the operation time of the specific operation affects the shortening of the tact time or the direction of the delay. It is preferable to perform a capability diagnosis based on this viewpoint.

  In the above embodiment, when displaying the diagnosis result on the display unit 38 in the ability recovery process (step S78 in FIG. 9), the recovery information and the component information are displayed in addition to the contents of the diagnosis result sheet. However, only the contents of the diagnosis result sheet may be displayed, and the display of the recovery information and component information may be omitted. In other words, if a related element correlated with the action is displayed in addition to the specific action, the operator can easily narrow down the cause based on the related element if the operator has some knowledge. For this reason, the function of displaying the recovery information and the component information may be omitted to simplify and reduce the cost of the apparatus.

  In the above embodiment, when there is an item that can be self-recovered in the diagnosis result sheet, the self-recovery process is executed after waiting for the operator's permission input, but it is executed without waiting for the permission input. You may do it. In addition, when the ability diagnosis target (specific operation) is only an item that can be self-recovered, for example, information such as the contents of the diagnosis result sheet is not displayed on the display unit 38, that is, the diagnosis result is notified to the operator. Alternatively, the self-recovery process may be executed.

  In the above embodiment, as an application example of the present invention, the capacity diagnosis apparatus for a mounting apparatus, which is a kind of work machine constituting the component mounting equipment, has been described. Of course, the capacity diagnosis apparatus of the present invention includes a component mounting equipment. The present invention can also be applied to other work machines that constitute.

The present invention can also be applied to an apparatus (dispenser) or a capability diagnosis apparatus such as an inspection apparatus that inspects the state of the substrate P after the printing process, the coating process, or the component mounting process.

  In this case, the specific operation (“operation name”) of the screen printing apparatus includes substrate carry-in operation, substrate reference mark recognition operation, substrate table positioning operation, substrate table raising and lowering operation, squeegee raising and lowering operation, squeegee The forward movement operation, the backward movement operation, the squeegee printing load control operation, the substrate carry-out operation, and the like are possible. Related elements (“element names”) related to these include a substrate conveyor drive motor, a substrate table drive motor, a substrate table lift drive motor, a squeegee head movement drive motor, and a squeegee lift pneumatic cylinder. In this case, the measurement target may be the current value to each motor, the original pressure value of the pressure air supply source to the pneumatic cylinder, or the like.

  In addition, specific operations (“operation names”) of the coating device (dispenser) include substrate carry-in operation, substrate reference mark recognition operation, dispenser head X-direction movement operation, Y-direction movement operation, cream solder, and the like. A discharge start operation from the start of the plunger moving operation for increasing the pressure in the syringe to the solder dropping, a coating operation from the discharge start to the discharge stop, a substrate carry-out operation, and the like are conceivable. Related elements ("element names") related to these include a substrate conveyor drive motor, a dispenser head X-direction drive motor, a Y-direction drive motor, and a plunger drive motor.
