Description

  The present invention relates to a component mounting device for mounting components such as electronic components on a substrate, and a warning notification device for notifying an operator of a warning for notifying that a device such as a component mounting device requires human intervention. And a warning notification method.

  In a component mounting system that manufactures a mounting substrate by mounting components such as electronic components on a substrate, for example, a plurality of component mounting apparatuses that mount electronic components on a substrate are connected.

  During operation of these component mounting apparatuses, various situations occur that require countermeasures by the operator who operates the apparatus, such as out of parts or apparatus stoppage due to machine trouble.

  The occurrence of these situations is automatically detected by a detection function provided in the apparatus itself. Furthermore, a warning for notifying that a human action is required is notified by a notification means using a signal lamp or a display panel.

  Then, the worker who has received these warnings accesses the apparatus and performs measures such as parts replenishment and machine trouble recovery.

For this reason, conventionally, a component mounting apparatus having a function of displaying necessary guidance information about the operation or operating state of the equipment is known so that the operator can appropriately execute such a treatment (for example, Patent Document 1).
JP-A-9-326599

  By the way, with the advancement of functions of various devices used in the component mounting field, information that can be automatically detected about the device operating state is diversified. In addition, the content of information notified from facilities in the form of warnings or guidance is diversified.

  For example, in a component mounting device, in addition to the contents that require immediate action, such as messages for prompting maintenance of each part such as error stop due to component failure or machine trouble, and clogging of the suction nozzle, the operation status of the device is changed. It is possible to display advisory warnings, etc. that prompt decisions on various actions that can be taken to improve and improve productivity.

  The former is notified to workers who are resident at the site of the component mounting line and operate each device. The latter is notified to a management worker who is a high-level worker who has a comprehensive judgment ability for measures required for improving productivity.

  However, in the prior art including the technique described in Patent Document 1 described above, these warnings are performed without specifying a notification target by a signal lamp, a display panel, or the like.

  For this reason, warnings that are clearly required to be dealt with immediately can be appropriately dealt with at the operator's own discretion, but have contents that require a high-level decision to improve productivity. In some cases, workers were unable to respond appropriately to warnings.

  As a result, the warning notified by the function of the device itself may be left without being transmitted to the management worker who is originally targeted for notification and may not be used effectively, resulting in an opportunity loss.

  On the other hand, even for warnings that require easy work, an inefficient situation occurs in which management workers who are not supposed to respond to the warnings are informed and bother the management workers. Was.

  As described above, in the conventional technology, the correspondence between the difficulty of the content of the response action for the alert to be notified and the worker to be notified has not been clarified, and thus the alert content is improved in productivity. Therefore, there is a problem that it may not be used effectively.

  In view of the above-described conventional problems, the present invention improves the certainty of transmission of a warning to be notified to a worker who is originally targeted for notification, thereby effectively improving the warning content for improving productivity.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, a configuration of a component mounting system having a function of mounting an electronic component on a substrate and manufacturing a mounting substrate will be described with reference to FIG.

  FIG. 1 is a diagram showing a configuration of a component mounting system according to an embodiment of the present invention.

  In FIG. 1, the component mounting system 1 includes a plurality of component mounting devices 50 connected in series on the downstream side of the board supply device M1. The component mounting system 1 is a system for manufacturing a mounting substrate by mounting components such as electronic components on a substrate using these devices.

  In order to distinguish each of the plurality of component mounting apparatuses 50, they are referred to as M2, M3, M4, and M5, respectively, as shown in FIG.

  The devices M2 to M5 have the same structure, and are connected to each other via the LAN system 2 and further connected to the host computer 3. The overall operation of the component mounting system 1 is comprehensively controlled by the host computer 3.

  The substrate supply device M1 has a function of storing a plurality of unmounted substrates and sequentially supplying these substrates one by one to the downstream device M2. The substrates supplied to the downstream device M2 by the substrate supply device M1 are transported to the downstream side in the order of the devices M2, M3, M4, and M5, and electronic components targeting each substrate by any device in this transport process Implementation work is executed.

  Each of the devices M2 to M5 uses, for example, a wireless LAN communication function of the host computer 3 to warn a specified worker among a plurality of workers (A, B, C,...). It has a function to notify.

  In the present embodiment, a warning is transmitted to the information receiving terminal device carried by the identified worker. The warning notification function of each of the devices M2 to M5 will be described later with reference to FIG.

  Next, the configuration of each of the devices M2 to M5, that is, the configuration of the component mounting device 50 will be described with reference to FIGS.

  FIG. 2 is a perspective view of the component mounting apparatus 50 according to the embodiment. FIG. 3 is a plan view of the component mounting apparatus 50.

  In the component mounting apparatus 50 according to the present embodiment, as described below, an electronic component is taken out from the component supply unit 8 by the component mounting mechanism 17, transported by the substrate transport mechanism 5, and positioned and held by the substrate positioning unit 6. It has a function of transporting and mounting the extracted electronic components on the substrate.

  2 and 3, the substrate transport mechanism 5 is disposed on the base 16 in the X-axis direction. A substrate positioning unit 6 is provided in the transport path by the substrate transport mechanism 5. The substrate 4 supplied from the upstream device and subjected to component mounting work by the component mounting device 50 is transported to the substrate positioning unit 6 by the substrate transport mechanism 5.

  The substrate positioning unit 6 positions the substrate 4 at the component mounting position by receiving and holding the conveyed substrate 4 from below. The component mounting operation on the board 4 by the component mounting mechanism 17 described below is performed in this state.

  The substrate 4 on which the component mounting operation has been completed is again transported to the downstream side by the substrate transport mechanism 5 and carried out to the downstream apparatus.

  Component supply units 8 are provided on both sides of the substrate transport mechanism 5, and a plurality of tape feeders 9 are attached to each component supply unit 8. The tape feeder 9 supplies electronic components held on the carrier tape to a component mounting mechanism 17 described below.

  At one end of the base 16 in the X-axis direction, a Y-axis moving table 10 having a linear drive mechanism is disposed horizontally in the Y-axis direction.

  The Y-axis moving table 10 is mainly composed of a beam member 10a provided in an elongated shape in the horizontal direction. A linear rail 10b is disposed in the horizontal direction on the beam member 10a. Two rectangular coupling brackets 11 are mounted on the linear rail 10b so as to be slidable in the Y-axis direction via linear blocks 10c.

  Similar to the Y-axis movement table 10, an X-axis movement table 12 having a linear drive mechanism is coupled to the two coupling brackets 11. A mounting head 13 is mounted on each X-axis moving table 12 so as to be movable in the X direction.

  The mounting head 13 is a multiple head including a plurality (eight in the present embodiment) of heads 14. A suction nozzle 14 a that sucks and holds an electronic component is attached to the lower end of each head 14. The suction nozzle 14a is moved up and down individually by a nozzle lifting mechanism built in the head 14.

  The Y-axis movement table 10 and the X-axis movement table 12 constitute a head movement mechanism. By this head moving mechanism, the mounting head 13 moves in the X-axis direction and the Y-axis direction. As a result, each head 14 takes out an electronic component from the tape feeder 9 of the component supply unit 8 and transfers and mounts the electronic component on the substrate 4 positioned by the substrate positioning unit 6.

  That is, the Y-axis movement table 10, the set of the X-axis movement table 12 and the mounting head 13 constitute a component mounting mechanism 17 that transfers and mounts electronic components on the substrate 4.

  A component recognition camera 7 is disposed between the component supply unit 8 and the board transport mechanism 5. The component recognition camera 7 images the electronic component held by the mounting head 13 when the mounting head 13 takes out the electronic component from the component supply unit 8 and moves above the component recognition camera 7.

  A substrate recognition camera 15 that is located on the lower surface side of the X-axis moving table 12 and moves with the mounting head 13 is mounted on the mounting head 13. As the mounting head 13 moves, the substrate recognition camera 15 moves above the substrate 4 held by the substrate positioning unit 6 and images the substrate 4.

  In the mounting operation of the electronic component on the substrate 4 by the mounting head 13, correction for a preset mounting position is performed.

  Specifically, the imaging result of the electronic component by the component recognition camera 7 and the imaging result of the board by the board recognition camera 15 are processed by the recognition processing unit 24 (described in FIG. 4 described later). The mounting position is corrected by adding the position recognition result obtained in this way to a preset mounting position.

  The component recognition camera 7 also functions as a sensor that detects the occurrence of a suction error in the suction nozzle 14a, for example. The board recognition camera 15 also functions as a sensor that detects, for example, a holding error of the board 4 in the board positioning unit 6.

  That is, the component recognition camera 7 and the board recognition camera 15 also function as sensors that detect a mechanical state in the mechanism unit 18.

  The component mounting mechanism 17, the component supply unit 8, the substrate transport mechanism 5, the substrate positioning unit 6, and the like are provided with sensors for operation confirmation and state monitoring at various places. If any abnormality occurs during operation of the apparatus, these sensors detect the state and output a signal corresponding to the detected state.

  For example, an operation confirmation sensor such as a cylinder switch or a stroke end detection sensor outputs a predetermined signal at a preset normal timing or sequence when the mechanism is operating normally. However, when an operation abnormality occurs, these signals are lost, or the signal generation timing is disturbed. That is, a signal indicating an abnormality sign is output from these sensors.

  Further, regarding the positional deviation of the tape feeder 9 in the component supply unit 8, the fall of foreign matter inside the mechanism, the clogging of the suction nozzle 14a and the valve, etc., a signal indicating the presence or absence of an abnormality is provided by a dedicated sensor provided for each. Sent out.

  Furthermore, the recognition processing unit 24 executes recognition processing according to a predetermined algorithm for the acquired image, and if a correct recognition result is not obtained due to a cause such as a defect of the acquired image, a recognition error is detected. Determine and send a signal to that effect.

  Next, the configuration of the control system will be described with reference to FIG.

  FIG. 4 is a block diagram illustrating a configuration of a control system of the component mounting apparatus 50 according to the embodiment.

  In FIG. 4, the overall control unit 20 includes a CPU for processing calculation, and controls each unit described below in an integrated manner.

  The storage unit 21 stores programs and data necessary for operations and processes for mounting electronic components on the substrate 4. The storage unit 21 further stores warning generation information 21a, warning level determination information 21b, and execution permission authentication information 21c necessary for warning processing described below.

  When the overall control unit 20 executes the mounting operation program stored in the storage unit 21, the mechanism control unit 23 is a mechanism including at least the substrate transport mechanism 5, the substrate positioning unit 6, the component supply unit 8, and the component mounting mechanism 17. The unit 18 is controlled.

  The overall control unit 20 and the mechanism control unit 23 realize a control function for the mechanism unit included in the control unit in the component mounting apparatus of the present invention.

  During the control process of the mechanism unit 18, a signal indicating whether the program execution state is normal is output from the overall control unit 20 by a monitoring function incorporated in advance in the operation program.

  For example, when a signal to be input from the sensor 35 that detects the state of the mechanism unit 18 is missing in the operation sequence, or when the signal is delayed beyond the allowable timing, some kind of operation abnormality occurs. It is judged that

  A plurality of sensors are attached to the mechanism unit 18 as described above. However, in order to clarify the description of the present invention, any one of the plurality of sensors or a combination of two or more sensors is expressed as “sensor 35”.

  The component recognition camera 7 and the board recognition camera 15 also function as sensors that detect the mechanical state in the mechanism unit 18 as described above. Therefore, the component recognition camera 7 and the board recognition camera 15 may be included in the sensor 35.

  Thus, in the component mounting apparatus 50 according to the present embodiment, the mechanical state in the mechanism unit 18 is detected, and the signal output from the sensor 35 and the mechanism unit 18 are operated according to the detected state. Therefore, when the overall control unit 20 executes the operation program, the component mounting apparatus 50 such as an operation abnormality or a state abnormality is caused by any human being based on one or both of the signals output from the overall control unit 20. A warning is generated to notify that a response action is required.

  That is, a warning corresponding to the type of these signals (one signal type or a combination of a plurality of signal types) is generated.

  In the present embodiment, as will be described below, these warnings are generated based on predetermined warning generation information 21a, and the level of the content of the warning is further determined.

  Specifically, a level indicating the difficulty level of the corresponding action to be performed in response to the warning is defined, and each worker is given execution permission authentication according to his / her ability or job title.

  The component mounting apparatus 50 according to the present embodiment identifies a worker who should execute the corresponding action in response to the warning based on the generated warning level and the execution permission authentication given to each worker. Furthermore, the warning is notified to the specified worker.

  Specifically, the processing from generation of warning to notification is performed by the warning notification device 40 included in the component mounting device 50.

  The warning notification device 40 includes a storage unit 21 and a warning processing unit 22. The storage unit 21 is a storage device that stores warning generation information 21a, warning level determination information 21b, and execution permission authentication information 21c.

  The warning generation information 21a, the warning level determination information 21b, and the execution permission authentication information 21c are information used in the warning process described above. Any information is created in advance and stored in the storage unit 21.

  The warning generation information 21a includes an input signal in the warning generation process, that is, a signal output from the sensor 35, a signal output from the overall control unit 20 when the operation program is executed, or a combination of these signals. It is information for making it correspond.

  A data configuration example of the warning generation information 21a will be described later with reference to FIG.

  The warning level determination information 21b is information that defines the correspondence between each warning and the level of execution permission authentication. A data configuration example of the warning level determination information 21b will be described later with reference to FIG.

  The execution permission authentication information 21c is information indicating what level of execution permission authentication is given to each worker belonging to the production line. A data configuration example of the execution permission authentication information 21c will be described later with reference to FIG.

  Here, the execution permission authentication is a so-called work given in advance to each worker who has a possibility of executing a corresponding action (work) for dealing with the content of the warning according to the degree of difficulty of the content of the corresponding action. It is a license. For each worker, one or more execution permission authentications are set in advance according to, for example, their abilities and positions.

  In the present embodiment, these pieces of information are stored in the storage units 21 of M2 to M5. However, such information may be stored in the host computer 3 as a database used in common by M2 to M5.

  The warning processing unit 22 has a function of executing processing for notifying the worker of various warnings based on these pieces of information. The warning processing unit 22 includes functions of a warning generation unit 22a, a warning level determination unit 22b, a warning notification unit 22c, and an execution permission / rejection determination unit 22d described below.

  The warning generation unit 22a generates a plurality of types of warnings for notifying that the component mounting device 50 needs some kind of human action based on the warning generation information 21a stored in the storage unit 21 in advance. Generate.

  As described above, the warning is generated by the sensor 35 detecting the mechanical state in the mechanism unit 18 including at least the component mounting mechanism 17, the component supply unit 8, the substrate transport mechanism 5, and the substrate positioning unit 6, and the state And the signal output from the sensor 35 and the signal output from the overall control unit 20 when the overall control unit 20 executes the operation program to operate the mechanism unit 18, or these signals It is executed based on a combination of signals.

  That is, by inputting these signals to the warning generation unit 22a, warnings having contents corresponding to the types of individual input signals or combinations of a plurality of types of input signals are generated based on the warning generation information 21a. .

  FIG. 5A is a diagram illustrating an example of a data configuration of the warning generation information 21a.

  The warning generation information 21a is information in which the type of signal output from the sensor 35 or the type of signal output from the overall control unit 20 is associated with the type of warning.

  Specifically, as shown in FIG. 5A, the correspondence between the input signal 28a and the generated warning 28b is recorded in the warning generation information 21a.

  The symbol such as “a” in the input signal 28a represents the type of signal, and the number such as “[1]” in the generated warning 28b represents the type of warning.

  As shown in the figure, there is a one-to-one correspondence between the input signal “a” and the warning “[1]”, or multiple input signals “b” or “c” and a warning “[2]”. There is a case to correspond. In some cases, a plurality of input signals “d” and “e” are associated with a warning “[3]”.

  Although not shown in FIG. 5A, there are various correspondence relationships such as a combination of three or more input signals and one warning.

  The warning generation information 21a further records a work group 28c corresponding to each of a plurality of warning types. A symbol such as “I” shown in the work group 28c represents a type of work to be performed in response to the warning, that is, a corresponding action, and is a type of information related to the warning.

  Thereby, the work group to which the work to be performed according to the warning generated by the warning generation unit 22a belongs is specified. This work group specifying process is executed by, for example, the warning generation unit 22a or the warning level determination unit 22b.

  The warning level determination unit 22b determines the level of the warning based on the identified work group and the warning level determination information 21b.

  In the present embodiment, it is assumed that each work corresponding to various warnings generated by the warning generation unit 22a is included in one of the work groups “I” to “VII”.

  FIG. 5B is a diagram illustrating an example of a data configuration of the warning level determination information 21b.

  The warning level determination information 21b is information in which information related to the generated warning is associated with the level.

  Specifically, as shown in FIG. 5B, the warning level determination information 21b records the correspondence between the level 29a and the work group 29b that is information related to the warning.

  The level 29a indicates the work to be executed as the corresponding action for dealing with the content of the generated warning, according to the difficulty level of the work, specifically, the judgment when executing the work and the difficulty level of the execution. They are classified into low-level general work and high-level management work.

  Further, each work group belonging to the general work is classified into the level 1 work group “I”, the level 2 work groups “II” and “III”, and the level 3 work group in order from the lowest difficulty according to the difficulty. Classified as “IV”.

  Similarly, each work group belonging to the management work is classified into a level 4 work group “V” and “VI” and a level 5 work group “VII” in ascending order of difficulty according to the difficulty level. .

  For example, the work belonging to the work group “V” is level 4, which means that the degree of difficulty is higher than the work belonging to the work group “III” being level 2.

  That is, the warning level determination unit 22b refers to the warning level determination information 21b for the level of the warning generated by the warning generation unit 22a and indicating the level of difficulty of the corresponding action to be performed in response to the warning. Judge by.

  Here, general work will be described. Events to be warned include misalignment of the tape feeder 9, clogging of the suction nozzle 14 a, clogging of foreign matter in the substrate transport mechanism 5, and stoppage of the apparatus due to a recognition error.

  These events occur frequently on a daily basis, and an immediate response is required unconditionally in order to continue the operation state of the apparatus, and postponement is not permitted. There are many such events.

  The work to deal with such an event is classified as a low-level work that is resident in the production line and should be executed as a general work by a line worker who is given a role as a simple operator.

  In other words, the warning requesting to deal with such an event is clearly shown in the work manual or the like as a response action because the content of the warning itself is easy to grasp. Therefore, it is possible for a worker who has undergone basic education and training to perform most of the work without difficulty.

  On the other hand, among warnings issued by the function of the apparatus itself, there is a high-level warning having an advisory meaning for improving the operating state of the apparatus and improving productivity. That is, there is a level of warning that requires management work that is more difficult than general work.

  For example, in each device (M2 to M5) constituting the component mounting system 1, the production efficiency of the device (the number of printed boards per unit time or the tact time indicating the required production time per board) is real-time. By measuring, a function of automatically detecting the advance or delay with respect to the production plan input in advance is provided. In addition, the production efficiency of the own device can be calculated in advance by simulation.

  For example, in the component mounting apparatus 50 of the present embodiment, the overall control unit 20 calculates an advance or delay with respect to the production plan by actual measurement or simulation by executing an operation program. Further, a signal indicating advance or delay with respect to the actually measured or calculated production plan is transmitted to the warning notification device 40.

  For example, when the warning notification device 40 receives a signal indicating that there is a delay with respect to the production plan, the warning notification device 40 determines whether there is a measure for recovering the delay. For example, when the received signal is recorded as the input signal in the warning generation information 21a, it is determined that there is an effective measure.

  Further, when the warning notification device 40 determines that there is an effective measure, the warning notification device 40 generates a warning corresponding to the input signal as an instruction warning for improving productivity. The generated warning is notified to the worker specified by a warning notification unit 22c described later.

  An example of an effective strategy is so-called optimization arrangement updating. The optimized arrangement is to optimize the arrangement of the tape feeders 9 in the component supply unit 8 or the mounting arrangement of the suction nozzles 14a in the mounting head 13 according to the type of the substrate 4 to be mounted with the components.

  That is, the purpose of the optimized arrangement is to eliminate the useless moving operation of the mounting head 13 in the component mounting operation and increase the operation efficiency as much as possible.

  In recent years, component mounting systems have been designed to perform such optimization computations in order to respond in real time to disturbances that are difficult to predict, such as machine troubles and occurrence timings of component breakage, and to maintain high operational efficiency at all times. A system has been introduced that allows device control to proceed while executing in the background.

  However, in order to execute such optimized arrangement, it is necessary to change the arrangement of the tape feeder 9 and the like after the apparatus in operation is temporarily stopped. Therefore, it is necessary to comprehensively determine whether or not to change the optimized layout in consideration of labor and time loss associated with the rearrangement.

  For this reason, when it is determined that there is a merit in updating the optimized arrangement, the component mounting device 50 issues a warning of meaning that prompts a comprehensive determination.

  Such a high-level content warning is difficult for a line operator who has a role as a mere operator to properly understand and judge the content. Therefore, it must be notified to a management worker who has a role as a production line management engineer.

  As described above, the levels of warnings issued from the component mounting apparatus 50 are various. Therefore, when a certain warning is notified, the effectiveness of the warning is lost unless it is notified to an operator who has the ability according to the level of the warning.

  Therefore, in the component mounting apparatus 50 according to the present embodiment, as described above, the warning level determination unit 22b determines the level of the warning generated by the warning generation unit 22a.

  Hereinafter, an example of warning generation by the warning generation unit 22a and warning determination by the warning level determination unit 22b will be described.

  For example, when a signal “a” indicating the occurrence of component breakage is input from the sensor 35 to the warning generation unit 22a, the warning generation unit 22a refers to the warning generation information 21a and reads “Replace component cutout feeder with new feeder”. "[1]" is generated.

  Further, the warning generation unit 22a refers to the warning generation information 21a, identifies the work group “I” corresponding to the warning “[1]”, and notifies the warning level determination unit 22b.

  The warning level determination unit 22b determines that the level corresponding to the notified work group “I” is “1” by referring to the warning level determination information 21b.

  Also, for example, when “d” and “e”, which are combinations of signals indicating that the time required for feeder replacement has exceeded the allowable range, are input to the warning generation unit 22a, the warning generation unit 22a generates a warning. With reference to the information 21a, a warning “[3]” containing “optimization of feeder arrangement for minimizing time required for feeder replacement” is generated.

  Further, the warning generation unit 22a refers to the warning generation information 21a, identifies the work group “VII” corresponding to the warning “[3]”, and notifies the warning level determination unit 22b.

  The warning level determination unit 22b determines that the level corresponding to the notified work group “VII” is “5” by referring to the warning level determination information 21b.

  Based on the warning level determined by the warning level determination unit 22b and the execution permission authentication information 21c, the warning notification unit 22c determines the worker who should be notified of the warning, that is, the worker to be notified. Identify.

  FIG. 5C is a diagram illustrating an example of the data configuration of the execution permission authentication information 21c.

  The execution permission authentication information 21c is information in which a warning level and information for identifying an operator are associated with each other.

  Specifically, as shown in FIG. 5C, the correspondence relationship between the warning level 30a and the authentication worker 30b is recorded in the execution permission authentication information 21c.

  The authentication worker 30b is information indicating the name and ID of the worker. In the execution permission authentication information 21c, a warning level 30a corresponding to work that can be executed by each worker is recorded. That is, each worker is given execution permission authentication according to their skill level or ability.

  The warning notification unit 22c stores, in the storage unit 21, processing for notifying the worker whose level is determined by the warning level determination unit 22b to an operator who has been granted execution permission authentication for the level. This is performed based on the execution permission authentication information 21c.

  It should be noted that the work corresponding to the warning level with “◯” in each column of the warning level 30a indicates that the execution permission authentication is given to the worker recorded in the row including the column.

  For example, the worker “A” may execute all the tasks included in the task groups corresponding to the level 1 to the level 5, that is, the task groups “I” to “VII”, regardless of the general task or the management task. It has been shown to be a worker with all-around capabilities possible.

  On the other hand, the worker “B” is a management worker, and the execution permission authentication is given only to the management work corresponding to the levels 4 and 5.

  Workers “C” and “D” are both line workers who are given execution permission authentication for general work only. Further, the worker “D” is not granted the execution permission authentication for the work group “IV” corresponding to the level 3 among the general work, and the executable range is limited.

  That is, the warning notification unit 22c identifies a worker who is given execution permission authentication for a level corresponding to the content of the notified warning among the workers registered in the execution permission authentication information 21c. Further, a warning is issued for this worker.

  For example, as described above, when the warning “[1]” having the content “replace component feeder with new feeder” is generated by the warning generation unit 22a, the corresponding work group is “I” ( (See FIG. 5A). Further, the level corresponding to the work group “I” is “1” (see FIG. 5B).

  In this case, the warning notification unit 22c refers to the execution permission authentication information 21c, and identifies the workers “A”, “C”, and “D” to which the execution permission authentication is given for level 1. The warning notification unit 22c further identifies, for example, “A” recorded at the top of the authentication worker 30b from among these workers.

  Further, for example, as described above, when the warning “[3]” containing “optimization of feeder arrangement for minimizing the time required for feeder replacement” is generated by the warning generation unit 22a. The work group to be performed is “VII” (see FIG. 5A). The level corresponding to the work group “VII” is “5” (see FIG. 5B).

  In this case, the warning notification unit 22c refers to the execution permission authentication information 21c, and identifies the workers “A” and “B” to whom execution permission authentication has been given for level 5. The warning notification unit 22c further identifies, for example, “B” to which execution permission authentication is given only for management work from among these workers.

  The warning notification unit 22c identifies the worker who should be notified of the warning in this way, and outputs it to notify the specified worker of the warning.

  In the present embodiment, the warning notification device 40 transmits a warning to the information receiving terminal device carried by the identified worker via the wireless LAN communication function of the host computer 3. As a result, a warning is issued.

  For example, when the worker “A” is identified, the warning notification unit 22 c reads “P001” that is the ID of “A” from the execution permission authentication information 21 c. The warning notification unit 22 c further transmits the warning generated by the warning generation unit 22 a and “P001” to the host computer 3. The host computer 3 that has received the information transmits the received warning to the information receiving terminal device corresponding to “P001”.

  As a result, the warning notification device 40 can notify the worker “A” whose ID is “P001” of a warning that prompts the worker that “A” is permitted to perform.

  Note that the warning notification device 40 may notify the specified worker directly of the warning without using the host computer 3. In this case, the warning notification device 40 only needs to have a communication function capable of transmitting information to the information receiving terminal device possessed by each worker.

  The information receiving terminal device that is the output destination of the warning by the warning notification device 40 is not limited to a specific form, and various devices can be used as the output destination of the warning.

  For example, as in the present embodiment, all workers may carry an information receiving terminal device capable of displaying the content of warning on the screen. Thereby, when each worker is notified of the warning, each worker can confirm the warning content at that time.

  At this time, as a screen display device of the information receiving terminal device, a glasses-type face-mounted personal monitor may be employed. In this case, if a warning screen is displayed in a part of the field of view, the worker who has received the warning can execute the work while confirming the content of the warning, thereby improving workability.

  Moreover, you may make each worker carry the simple terminal device which can display the character etc. which show only that the warning generate | occur | produced as an information receiving terminal device.

  In this case, a reception device capable of displaying a screen showing the warning content is shared by a plurality of workers. Further, this receiving apparatus is installed in a predetermined place.

  Then, the worker who has received the warning for himself at the simple terminal device accesses the predetermined place and confirms the display screen of the receiving device. Thereby, the warning can be notified to the worker specified by the warning notification device 40.

  In addition, information indicating that a warning has occurred and the component mounting apparatus 50 that is the generation source of the warning may be displayed on the simple terminal device.

  In this case, the worker who has received the warning for himself / herself in the simple terminal device accesses the component mounting device 50 shown in the simple terminal device, and confirms the display content of the display unit 26 provided in the component mounting device 50. . By doing so, the warning can be notified to the worker specified by the warning notification device 40.

  Alternatively, information indicating the warning content and the ID of the worker to be notified may be output with the information receiving terminal device of all workers as the destination.

  Further, for example, a large display device may be installed at a position where each worker can visually recognize, and the content of the warning and the ID of the worker who is a warning notification target may be displayed on the display device.

  Further, the warning may be notified only by voice. For example, a speaker may be connected to the host computer 3, and the speaker may be configured to output sound indicating the content of the warning and the ID of the worker who is the alert notification target.

  Further, the warning notification may be performed by, for example, lighting, blinking or color of light, vibration of the information receiving terminal device, or a combination thereof, instead of characters, symbols, figures, or sounds.

  In this case, it is only necessary for each worker to recognize the correspondence between the type of lighting of the light, the content of the warning, and the person to be notified of the warning.

  In any of these cases, the generated warning is notified to the worker specified according to the level of the warning.

  The execution permission / refusal determination unit 22d determines whether or not an operator who has accessed the device in order to perform a corresponding action in response to notification of a certain warning has been granted execution permission authentication for a level corresponding to the content of the warning. The determination is made by referring to the execution permission authentication information 21c.

  Furthermore, the execution permission / refusal determination unit 22d performs a process of granting the execution permission of the corresponding action to the worker according to the determination result.

  That is, at the production line site, the worker who receives the warning notification from the warning notification device 40 does not necessarily execute the corresponding action. For example, the worker may not be able to respond for some reason.

  In such a case, it is necessary to perform a response action by an alternative worker for the notified warning. However, this alternative worker is not necessarily the worker who is given the authorization to execute the corresponding action. Therefore, it is necessary to confirm again whether or not the execution permission authentication of the worker is present.

  For this reason, an operator who accesses the component mounting apparatus 50 is required to input his / her ID into the operation unit 25 of the apparatus, for example. The warning processing unit 22 of the device determines whether or not execution permission is appropriate for the worker based on the input ID and the execution permission authentication information 21c.

  For example, when the worker “D” intends to replace the component-cut feeder with a new feeder, the worker “D” inputs his / her ID “P004” from the operation unit 25 to the component mounting apparatus 50. Further, the operator “D” is performed from the operation unit 25 that performs a predetermined operation for executing the replacement of the tape feeder 9.

  The execution permission / refusal determination unit 22d specifies that the work group corresponding to the feeder replacement is “I” by referring to information (not shown) indicating the correspondence between the work content and the work group.

  The execution permission / refusal determination unit 22d further refers to the warning level determination information 21b and the execution permission authentication information 21c. Thereby, the worker whose ID is “P004” confirms that “level 1”, which is a level corresponding to the work group “I”, is given.

  After this confirmation, the execution permission / refusal determination unit 22d permits the operator “D” to replace the feeder. For example, the execution permission determination unit 22d displays on the display unit 26 that work is permitted, and causes the overall control unit 20 to stop the operation of the mechanism unit 18 for replacing the tape feeder 9 or the like.

  The recognition processing unit 24 performs recognition processing on the imaging results obtained by the board recognition camera 15 and the component recognition camera 7. As a result, the position of the component mounting target board 4 and the position of the electronic component held by the mounting head 13 are recognized.

  The operation unit 25 is an input unit such as a keyboard or a touch panel, and an operator inputs an operation command or data from the operation unit 25.

  The display unit 26 is a display panel such as a liquid crystal panel, and displays a guidance screen at the time of operation input by the operation unit 25 and various warning contents.

  The communication unit 27 transmits and receives signals between the control function of the component mounting apparatus 50 and another apparatus or the host computer 3.

  Next, the operation when the component mounting apparatus 50 notifies the worker of a warning will be described with reference to FIGS. 6 and 7.

  FIG. 6 is a flowchart illustrating a basic processing flow when the component mounting apparatus 50 according to the embodiment performs the warning notification processing.

  In the component mounting apparatus 50, the sensor 35 detects a mechanical state in the mechanism unit 18 and outputs a signal. Further, the overall control unit 20 executes the operation program to output a signal indicating that some kind of treatment is necessary (ST10).

  The warning generation unit 22a receives a signal from at least one of the sensor 35 and the overall control unit 20. The warning generation unit 22a further generates a warning corresponding to the type of the received signal by referring to the warning generation information 21a (ST11).

  That is, the warning generation unit 22a gives a warning for notifying that the component mounting device 50 requires some human action, the type of the signal output from the sensor 35, or the overall control unit 20 operating program. Is generated by referring to the warning generation information 21a in which the type of signal output from the overall control unit 20 and the type of warning are associated with each other (warning level generation step).

  The warning level determination unit 22b refers to the warning level determination information 21b to specify the level corresponding to the work group. Thereby, the level of the warning is determined (ST12).

  That is, the warning level determination unit 22b is a level of the warning generated by the warning generation unit 22a, and indicates a level indicating the difficulty level of the corresponding action to be performed according to the warning, information related to the warning, Determination is made by referring to the warning level determination information 21b associated with the level (warning level determination step).

  The warning notification unit 22c identifies the worker corresponding to the level by referring to the execution permission authentication information 21c (ST13). The warning notification unit 22c further outputs the warning to notify the identified worker (ST14).

  That is, the warning notification unit 22c identifies the worker permitted to perform the corresponding action according to the warning generated by the warning generation unit 22a, and the level determined by the warning level determination unit 22b and the worker. It is specified by referring to the execution permission authentication information 21c associated with the information to be output, and is output to notify the specified worker of the warning.

  In the present embodiment, the warning notification unit 22c transmits information indicating the warning generated by the warning generation unit 22a and information indicating the identified worker ID to the host computer 3 as described above.

  The host computer 3 transmits information indicating the received warning with the information receiving terminal device corresponding to the ID as a destination.

  The above is the basic processing flow when the component mounting apparatus 50 notifies the worker of a warning.

  In addition to the basic processing described above, the component mounting apparatus 50 according to the present embodiment performs processing such as recording notification contents and determining whether work is permitted or not by an operator.

  An example of the flow of processing executed by the component mounting apparatus 50, including processing other than the basic processing described above, will be described with reference to FIG.

  FIG. 7 is a flowchart illustrating an example of a flow of processing executed by the component mounting apparatus 50 according to the embodiment.

  First, in the apparatus operating state, when an event to be warned occurs, the sensor 35 detects the event and outputs a signal. Further, a signal indicating that some kind of treatment such as an increase in tact time is necessary is output from the overall control unit 20 (ST100).

  The warning generation unit 22a generates a warning corresponding to the type of these signals (ST101).

  Next, the warning level determination unit 22b determines whether or not the generated warning level is high (ST102). When the level determined by the warning level determination unit 22b is “4” or “5”, it is referred to as “high level (high level)” (see FIG. 5B).

  Here, as a result of the determination by the warning level determination unit 22b, when the generated warning level is high (YES in ST102), the warning notification unit 22c is a management worker who is a notification target of the warning, that is, An operator having a role as a line management engineer who is given execution permission authentication for a level is specified. The warning notification unit 22c further outputs the warning to notify the identified worker (ST103).

  Specifically, the warning notification unit 22c specifies an operator who is a warning notification target with reference to the execution permission authentication information 21c illustrated in FIG. Furthermore, in this embodiment, the warning notification unit 22c transmits a warning to the information receiving terminal device carried by the worker via the host computer 3.

  In addition, when a worker who is notified of a warning is specified and there are a plurality of registered workers who have been given the same execution permission authentication, a ranking that is determined in advance as a priority when specifying the worker as a target. Follow.

  Along with this warning notification, the notification content and the target person are recorded (ST104). That is, information that combines the name or ID code of the target management worker and the notification date is written in the production management log as warning notification recording data.

  This warning notification recording data is intended to record the work history of each worker and to be used as basic data for evaluating and determining the learning progress of each worker.

  The production management log may be provided in the storage unit 21 of each apparatus or in a database of the host computer 3.

  Further, the writing of the warning notification record data to the production management log is performed by, for example, the warning notification unit 22c.

  Next, when the management worker who has received the notification accesses the component mounting apparatus 50, the warning notification apparatus 40 included in the component mounting apparatus 50 accepts the management worker's response (ST105).

  That is, the execution permission determination unit 22d acquires the management worker ID input from the operation unit 25, and refers to the execution permission authentication information 21c. Thereby, it is determined whether or not the management worker who has accessed the component mounting apparatus 50 is a worker who has been given execution permission authentication for the level corresponding to the content of the warning. The execution permission / rejection determination unit 22d further grants execution permission of the corresponding action to the management worker according to the determination result (permission / rejection determination step).

  Next, when the management worker makes a necessary determination and finishes the corresponding action such as inputting a predetermined instruction from the operation unit 25, the name of the management worker who performed the corresponding action and the content of the corresponding action (response contents) ) Is recorded (ST106).

  For example, the execution permission determination unit 22d writes these pieces of information as response record data in the above-described production management log.

  Then, for example, the execution permission / refusal determination unit 22d determines whether or not the line worker needs to be handled in accordance with the above-described response action (ST107).

  This determination is performed as follows, for example. After completion of the work by the management worker, the execution permission determination unit 22d determines whether or not a warning needs to be generated based on the type of signal output from the sensor 35 and the warning generation information 21a.

  If the result of the determination is NO (NO in ST107), the necessary processing is performed by the function provided in the component mounting apparatus 50 itself without requiring any manual operation by the line operator (ST109).

  If the result of the determination is YES (YES in ST107), a warning indicating the necessary work content is notified to the target line worker (ST108).

  Specifically, the warning generation unit 22a generates a warning, and the warning level determination unit 22b determines the level of the warning.

  And the warning alerting | reporting part 22c specifies the line worker to whom the execution permission authentication about the determined level was provided. The warning notification unit 22c further transmits a warning via the host computer 3 to the information receiving terminal device carried by the line operator.

  In the initial warning level determination process (ST102) by the warning level determination unit 22b, even when it is determined that the warning level is low (NO in ST102), a warning is given to the line operator (ST108). ).

  Along with the notification of the warning to the line worker, the notification content and information for identifying the line worker are recorded (ST110). That is, information combining the name or ID code of the target line operator and the notification date is written as warning notification recording data in the production management log.

  The writing of the warning notification record data is also performed for the same purpose as the above-described recording of the name of the management worker (ST106), and is executed by the warning notification unit 22c, for example.

  Next, when the line worker who has received the notification accesses the device, the warning notification device 40 included in the component mounting device 50 accepts the execution of the corresponding work by the line worker (ST111).

  That is, whether or not the execution permission determination unit 22d refers to the execution permission authentication information 21c, so that the line worker who has accessed the component mounting apparatus 50 is given execution permission authentication for the level corresponding to the content of the warning. Determine whether or not. The execution permission / rejection determination unit 22d further grants execution permission of the corresponding action to the line worker according to the determination result (permission / rejection determination step).

  Next, when the line worker finishes the corresponding action, the name of the line worker who performed the corresponding action and the content (response content) of the corresponding action are recorded (ST112).

  For example, the execution permission determination unit 22d writes these pieces of information as response record data in the above-described production management log.

  From the above processes, a series of warning notification processes in the component mounting apparatus 50 is completed.

  As described above, the component mounting apparatus 50 according to the present embodiment generates a warning for notifying that it needs some human action by referring to the warning generation information 21a. Further, the level of the generated warning is determined by referring to the warning level determination information 21b.

  Also, the worker who is given execution permission authentication for the level is specified by referring to the execution permission authentication information 21c. Furthermore, it outputs in order to alert | report the said warning to the specified operator.

  Thereby, it is possible to improve the certainty of transmission of the warning to be notified to the worker who is originally targeted for the notification. That is, according to the present invention, the warning content can be effectively used for improving productivity.

  Moreover, since each worker requires a work corresponding to his / her ability, job title, and the like, each worker can efficiently perform the work without performing unnecessary actions.

  In the present embodiment, the component mounting device 50 includes the warning notification device 40. In other words, each of M2 to M5 includes the warning notification device 40.

  However, each of the devices M2 to M5 may not include the warning notification device 40. That is, the warning notification device 40 may exist in the component mounting system 1 as a device independent of M2 to M5.

  For example, the warning notification device 40 may be realized by a CPU, a program, a storage device, and the like included in the host computer 3.

  In this case, the host computer 3 may receive the output signal of the sensor 35 from each of M2 to M5, and generate and output a warning. Moreover, what is necessary is just to determine permission of execution of work by acquiring ID, operation content, etc. which were input by the operator from each of M2 to M5, and referring to the execution permission authentication information 21c.

  By doing so, for example, the contents of troubles occurring in each of M2 to M5 and the contents of countermeasures to troubles can be centrally managed.

  Further, the warning notification device 40 may notify a warning for notifying that the device included in the component mounting system requires some human action.

  For example, inspecting substrate supply devices that supply substrates to other devices, printing machines that apply cream solder to substrates, adhesive applicators that apply adhesive to substrates, reflow ovens that perform reflow, and component mounting conditions An apparatus included in a component mounting system for mounting components on a substrate, such as an appearance inspection machine, may be a monitoring target for warning notification.

  Each of these various devices includes a sensor that detects the state of the device and outputs a signal corresponding to the detected state. Each of these various apparatuses includes a control unit that operates the apparatus by executing an operation program. Further, each of these various devices includes an operation unit that receives input and operation of information from an operator.

  The warning notification device 40 communicates with any of these various devices and receives an output signal of at least one of the sensor or the control unit from the device. Furthermore, based on the type of the received signal, the warning generation information and the warning level determination information corresponding to the device are referred to so that the output from the generation of the warning and the execution permission / inhibition are determined.

  Further, the ID, operation content, and the like input by the operator are acquired from the device, and whether or not the work is permitted is determined by referring to the execution permission authentication information for the device.

  Note that the flow of each of these processes is the same as that shown in FIGS. 6 and 7.

  In this manner, the warning notification device 40 can transmit a warning related to the communication partner device to an appropriate worker by communicating with various devices used in the mounting process.

  In addition, the component mounting apparatus 50 according to the present embodiment includes the two mounting heads 13 arranged to face each other.

  However, the device to be monitored by the warning notification device 40 for warning notification may be a component mounting device having another structure. For example, the apparatus may be provided with only one mounting head that picks up components and mounts them on a substrate. Further, for example, a rotary type component mounting apparatus may be used.

  Further, the warning notification device 40 of the present embodiment refers to the three tables of the warning generation information 21a, the warning level determination information 21b, and the execution permission authentication information 21c shown in FIGS. 5 (A) to 5 (C). And from the generation of warning to the output.

  However, the number of tables may be other than 3 as long as necessary information from generation to output of warnings is included.

  For example, the determination of the warning level and the identification of the worker may be performed by referring to one table.

  FIG. 8 is a diagram illustrating an example of a data configuration of the execution permission authentication information 21d including information necessary for determining the warning level.

  The execution permission authentication information 21d illustrated in FIG. 8 is information indicating the correspondence between the work group and the level and the correspondence between the level and the worker.

  For example, when the warning generated by the warning generation unit 22a is “[3]”, the work group corresponding to “[3]” is “VII” (see FIG. 5A). In this case, the warning level determination unit 22b can determine that the level corresponding to the work group is “5” by referring to the execution permission authentication information 21d.

  Further, the warning notification unit 22c can identify the workers who are granted the level 5 execution permission authentication as “A” and “B” by referring to the execution permission authentication information 21d. In this case, the warning notification unit 22c identifies, for example, “B” to which execution permission authentication is given only for management work as an operator who performs work in accordance with the warning.

  Further, for example, warning generation and warning level determination may be performed by referring to one table.

  FIG. 9 is a diagram illustrating an example of a data configuration of the warning generation information 21e including information necessary for determining the warning level.

  The warning generation information 21e shown in FIG. 9 is information indicating the correspondence between the signal type and the warning type, and the correspondence between the warning type and the level. That is, the warning generation information 21e includes information indicating a correspondence between a warning type and a level, which is information related to the warning.

  For example, when the warning generation unit 22a receives the signal “d” and the signal “e”, the warning generates “[3]” by referring to the warning generation information 21e. In this case, the warning level determination unit 22b can determine that the level corresponding to the work group is “5” by referring to the warning generation information 21e.

  As described above, if the information group included in the warning notification device 40 is an information group that can generate a warning, determine the level of the generated warning, and identify the worker corresponding to the determined level, the information group The grouping of various types of information included in is not limited to a specific one.

  The component mounting device, the warning notification device, and the warning notification method according to the present invention improve the certainty of transmission of the warning to the worker who is originally targeted for notification, thereby improving the warning content. Therefore, it has an effect that it can be effectively used. Therefore, the present invention is useful for a system and apparatus for manufacturing a mounting board by mounting electronic components on a board.
