Description

The present invention relates to components mounter is mounted on a substrate, component matching method for matching using a computer, the method component information management component mounting how, and the component mounting machine, in particular, performs the part matching parts The present invention relates to a technology for exhibiting high working efficiency using a simple input device in a mounting system.

  Conventionally, production management operations such as component verification and device maintenance at a component mounting site are generally performed using a computer system to which a scanner capable of reading a barcode is connected. Such production management work is performed by an operator reading a bar code representing various information such as a part name and a part feeder ID with a scanner.

  At this time, using a handy scanner equipped with a display screen, by displaying information related to work on the display screen, a technique for improving the work efficiency by making the interaction with the computer system more efficient at the hands of the operator is known. ing.

As a specific example, Patent Document 1 discloses a technique for performing maintenance management of a parts feeder in a component mounter based on information displayed on a display screen provided in a scanner.
JP-A-2005-244175

  However, according to the technique disclosed in Patent Document 1, an efficient dialogue between the operator and the computer system is realized, but a scanner having a display screen is necessary, which is disadvantageous in terms of the cost of the computer system.

  However, if an inexpensive scanner that does not have a display screen as in the past is used, there is a significant inconvenience in terms of work efficiency, especially in parts collation work. This is because, in most component mounting sites, only one component verification device is installed on one mounting line, and the operator can obtain information necessary for verification each time on the component mounting machine component. This is because it is necessary to go from the supply unit to the screen of the component verification device.

  As an example, the operator goes to the screen of the component verification device to confirm the operation guidance instructed to read with the scanner, returns to the component supply unit of the component mounter, operates the scanner, executes the instruction, While performing a series of component verification operations, such as going to the component verification device screen again and confirming the execution result, the number of times between the component supply unit of the component mounter and the screen of the component verification device is You have to go back and forth.

  The present invention has been made in view of such circumstances, and performs production management work at a part mounting site, in particular, part collation work, using an input device that does not have a display screen, and with good work efficiency. The purpose is to provide a technology that makes it possible.

  In order to achieve the above object, the component collation method according to the present invention can input whether or not a component arranged in a component supply unit that supplies a component to be mounted by a component mounter is appropriate by a portable input device. A component collation method for collation using a computer system, wherein the assembly of components sets a detection step of detecting an operation performed on the portable input device with respect to the collation of the component, and data relating to the operation. Display step of displaying on the display screen of the component mounter to be performed.

  The data relating to the operation may be a guidance for guiding the operation or a result of processing performed in response to the operation, and the portable input device is a scanner device capable of reading a barcode. May be.

  According to this configuration, the operator operates the portable input device at hand, and can confirm data related to the operation on the display screen of the component mounter as the work place, so that a smooth dialogue is realized. Accordingly, it is possible to perform a component collation operation with good work efficiency using a scanner having no display screen.

  Here, the component mounter includes a plurality of display screens, and in the display step, data related to the operation is preferentially displayed on a display screen close to a place where the component collation operation is performed from the plurality of display screens. It is desirable to display. Furthermore, the display step may occupy the display screen and prohibit display of data related to operations performed on other portable input devices on the display screen.

  Therefore, the component mounter includes a plurality of component supply units, and further includes a specifying step of specifying a component supply unit in which the assembly of the components is to be set from the plurality of component supply units, In the display step, data related to the operation is preferentially displayed on a display screen close to the specified component supply unit, and further includes a specifying step of specifying the portable input device on which the operation is performed, In the display step, data related to the operation can be preferentially displayed on a display screen close to the position of the specified portable input device.

  More preferably, the component mounter is disposed on a mounting line, the plurality of display screens are disposed on a front side and a rear side as viewed from one side of the mounting line, and the plurality of component supply units are mounted on the mounting line. It is arranged on the front side and the rear side when viewed from one side of the line, and in the specifying step, it is specified whether the component supply unit on which the assembly of the components is to be set is the front side or the rear side, and in the display step, the specifying The data related to the operation may be preferentially displayed on the display screen on the side where the operation is performed.

  According to this configuration, since the data related to the operation is displayed on the display screen close to the operator's work place, the convenience of the operator is improved and the work efficiency is improved.

  Further, in the display step, the display screen content of the component mounter is switched to the screen content related to the component verification work in accordance with a display switching operation performed by an operator, and the component verification method is displayed in the display step. May be displayed on the display screen of the component mounter.

  According to this configuration, since a relatively large amount of various data can be efficiently presented to the operator, in addition to the original data of the component mounter, for example, the operator can select a component list that spans multiple mounting lines. It is possible to acquire information, collation work state information indicating the state of the collation work of parts, and the like, and use it for collation work of parts.

  The component collation method may further include a sound generation step for causing the portable input device to output a dial tone when displaying data in the display step.

  According to this configuration, the operator can hear the dial tone from the input device at hand and immediately check the display screen to confirm the message. In particular, when an error message is displayed on the display screen, the operator can immediately recognize the content by the dial tone and deal with the error.

The present invention not only can be realized as such a component matching method, method component information management component mounting how, and can be realized as a component mounting machine.

  According to the component verification method of the present invention, data related to operations performed on the portable input device regarding component verification is displayed on the display screen of the component mounter on which the assembly of components is to be set. Using a scanner that does not have a display screen, it is possible to perform a component collation operation with good work efficiency.

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

<System configuration>
FIG. 1 is a schematic diagram showing an example of a configuration of a component mounting system including a component verification device according to an embodiment of the present invention.

  The component mounting system 1 is a system that collates components and mounts the collated components on a board. The component mounting system 1 includes a component collation device 10, mounting lines 20 and 30, a display device 40, and a LAN (Local Area Network) 50. Is done.

  The mounting line 20 is a system that transports a board from production equipment on the upstream side to production maintenance on the downstream side and produces a board on which components are mounted. The component mounting machines 21 to 24, scanners 27a, 27b, 28a, and 28b. And scanner ports 29a and 29b. In addition to this, the actual mounting line includes a stocker, a solder printing device, a reflow furnace, and the like, but the illustration is omitted here. The mounting line 30 has the same configuration as the mounting line 20.

  Here, component verification refers to whether or not a component arranged in a component supply unit that supplies a component to be mounted by a component mounter is appropriate, depending on whether or not a verification condition recorded in advance in the component verification device 10 is successful. Say the task of judging. As a typical example, component verification is performed when a component reel is hung on a component mounter in a setup operation, which is a preparatory work before mounting a component, and confirms that the newly placed component is appropriate. Guarantee.

  In addition to this, for example, when a component breakage occurs and a new component reel is put on a component mounter, when a jammed state in which the feeding operation becomes impossible due to clogging of the component tape is resolved, and before the component is cut When splicing various component tapes, etc., it is performed according to the procedure according to each situation to ensure that the components to be arranged are appropriate. A specific example of component matching will be described in detail later.

  The component verification apparatus 10 may further manage the component information by fetching information on a component that is confirmed to be a correct component by performing component verification. Further, management of information on a component confirmed as a correct component by the component verification device 10 may be performed by an independent component management information device realized by another computer system.

  The component verification device 10, the component mounters 21 to 24, the scanner ports 29a and 29b, and the display device 40 of the mounting line 20 are connected via the LAN 50 and should be displayed on the control command, command response, and display device. Data and data read by the scanner are exchanged.

  The scanners 27a and 28a and the scanner port 29a exchange control commands, command responses, and read data by wired communication or wireless communication using, for example, infrared rays or radio waves. The same applies to the scanners 27b and 28b and the scanner port 29b.

<Component mounter>
FIG. 2 is a perspective view showing an example of the component mounting machine 20.

  The component mounter 20 is a device that mounts components on a board, and includes two sub-equipment 230a and 230b that perform component mounting in cooperation with each other (or in an alternating operation). The sub-equipment 230a and 230b includes display screens 250a and 250b, respectively.

  The sub-equipment 230a includes a component supply unit 224a including an array of feeders 223 for supplying components, and a multi-mounting head 221 having a plurality of suction nozzles that can suck the components supplied from the feeders 223 and mount them on a substrate. The beam 222 to which the multi-mounting head 221 is attached, the component recognition camera 226 for inspecting the suction state of the component sucked by the multi-mounting head 221 two-dimensionally or three-dimensionally, state information of the component mounting machine 20, etc. Display screen 250a. The sub-equipment 230b has the same configuration as the sub-equipment 230a.

  Here, as an example, the component supply unit 224a is divided into two areas on the left and right sides toward the component mounter 20. Each divided area is called a table. Therefore, the table indicates a part of the component supply unit. Using the exchange cart, all the feeders of the table can be exchanged in a batch unit. From this, it can be said that the table is a unit for batch exchange. The sub-equipment 230b also has two tables on the rear surface that are not shown.

<Parts verification device>
FIG. 3 is a block diagram illustrating an example of a functional configuration of the component verification apparatus 10.

  The component verification device 10 is a device that acquires data read by a scanner in accordance with an operation of an operator, and checks whether or not the component is appropriate based on the acquired data. The input data processing unit 11, display destination management It comprises an information storage unit 13, a collation execution unit 14, an input / output unit 15, and a communication I / F unit 16. The input data processing unit 11 includes a display destination specifying unit 12. The input / output unit 15 is realized using a liquid crystal display, a keyboard, or the like.

  The collation execution unit 14 controls and executes the entire component collation process by detecting a data scan operation performed on the scanner by the operator and activating the input data processing unit 11.

  The input data processing unit 11 acquires scanned data from the scanner in accordance with an operator's operation, and determines whether the acquired data satisfies a verification condition.

  The display destination management information storage unit 13 stores scanner display destination management information for managing display destinations corresponding to one or more scanners.

  The display destination specifying unit 12 refers to the display destination management information stored in the display destination management information storage unit 13 and specifies a display screen close to the place where the component collation operation is performed.

  The input data processing unit 11 displays the result of the determination on the display screen specified by the display destination specifying unit 12. Further, the input data processing unit 11 displays guidance for guiding the next operation to be performed on the scanner on the display screen specified by the display destination specifying unit 12.

  The verification execution unit 14 transmits a control command for causing the component mounter and the scanner to perform a predetermined operation according to the determination result of the verification condition for the acquired data.

  In the following, first, after describing in detail the function of preferentially displaying the data related to the scanner operation on the display device close to the work place where the component verification operation is performed, which is the greatest feature of the component verification device 10, the component verification is performed. A specific example of the entire component matching process performed by the apparatus 10 will be described.

<Display management information>
FIG. 4 is a diagram illustrating an example of display destination management information stored in the display destination management information storage unit 13.

  This display destination management information can be used by the scanners 27a, 27b, 28a, and 28b in the mounting line 20 of FIG. 1 for collation of components set in the tables of the component mounters 21 to 24, and is currently used. Indicates whether it is inside.

  FIG. 5 is a schematic view of the mounting line 20 as viewed from above. In FIG. 5, the component mounter, the table of the component mounter, the display screen of the component mounter, the scanner port, the scanner, and the operator are shown using identification names instead of the reference numerals in FIG.

  M01 to M04 are machine names for identifying the component mounters 21 to 24. TBL1 to TBL4 are table names for identifying tables provided in the respective component mounters. DSP1 and DSP2 are display screen names for identifying display screens included in the respective component mounters. SP1 and SP2 are scanner port names for identifying the scanner ports 29a and 29b. S1 to S4 are scanner names for identifying the scanners 27a, 27b, 28a, and 28b. OP1 to OP4 are operator names for identifying operators. The following description will be given using this identifier. The component mounter is also simply called a machine.

  For convenience of explanation, in the mounting line 20, the operator performs the collation operation for the components set in the tables TBL1 and TBL3, and the operator performs the collation operation for the components set in the tables TBL2 and TBL4. I will call it.

  In FIG. 4, a white circle indicates that the scanner can be used for collation of the parts set in the table, and a black circle indicates that the scanner is currently in use for collation of the parts set in the table. Represents.

  In addition, the display destination management information in FIG. 4 shows a display screen close to the place where the component matching operation is performed, corresponding to the component mounter and the table.

  Accordingly, these white circles and black circles are displayed on the display screen DSP1 on the front side near the work location, and the data related to the operation of the scanners S1 and S2 used for the work on the front side are displayed on the rear side. It also indicates that the data related to the operations of the scanners S3 and S4 used for the work is displayed on the display screen DSP2 on the rear side close to the work place.

  FIG. 6 is a diagram for explaining the concept of the display destination lock process. The lock process is a process that occupies a display screen as a display destination with one scanner and prohibits display of data related to operations performed on other scanners on the display screen. In order to prohibit the display of data related to other scanners on the display screen occupied by a certain scanner, for example, an error message may be displayed on the display screen for other scanners.

  FIG. 6 shows that when both of the scanners S1 and S2 arranged on the front side can be used for the collation operation of the components set on the front table of the component mounting machines M01 to M04, the scanner S1 becomes the component mounting machine M01. Indicates that the scanner S2 is only used for component verification in component mounting machines other than the component mounting machine M01.

  Accordingly, the display screen DSP1 on the front side of the component mounting machine M01 is occupied by the scanner S1, in other words, the place where the scanner S1 is used is locked, so that confusion of the scanner to be used can be avoided. The same can be said of course between the rear table and the scanner arranged on the rear side.

  Note that the lock can be released when the component collation process is completed, for example.

<Input data processing>
Next, input data processing performed by the input data processing unit 11 will be described.

  FIG. 7 is a flowchart illustrating an example of input data processing. This process determines the suitability of the data (for example, operator ID, reel ID, part name, lot name, vendor name, remaining number, etc.) acquired from the scanner in the entire component verification process described later, and determines the result. This is processing of a part that specifies a display screen to be displayed and displays the result on the specified display screen.

  Each time the operator scans data by scanner operation, this processing is started from the collation execution unit 14 that has detected the scanner operation by the operator, specifying the scanner from which the operation was detected.

  The input data processing unit 11 identifies the scanner designated at the time of activation as the scanner that has been operated. This specified scanner is hereinafter referred to as a target scanner. Then, by acquiring and analyzing input data from the target scanner (S21), it is determined whether or not the input data satisfies the collation condition, and the result of the determination is held (S22).

  The collation condition is a condition for determining that the input data is appropriate, and is determined in advance according to the type of data. As an example of the part name, there is a condition that the content of the acquired data matches the part name predetermined by the production program.

  When the input data processing unit 11 acquires a part name or a reel ID (a reel ID includes a part name in a system managed at a mounting site, as will be described later), the part name or Work location where the component mounter and the table to which the feeder belongs are collated with reference to the production program that defines the feeder of the component mounter on which the assembly of components indicated by the reel name is to be set As specified.

  In the following, for the sake of simplicity, the specified component mounter and the table are referred to as a work place, but it should be noted that the place where the operator actually performs the collation work is the table and its surroundings. Each column of the display destination management information shown in FIG. 4 corresponds to this work place.

  Since the work location is not specified for the data entered before the part name or reel ID (NO in S24), it is indicated that the target scanner is usable and all other scanners are not currently in use. The display destination management information is updated to indicate that the target scanner is currently in use at the work place (S27). Thereby, even when the work place is not specified, the process can proceed with the display screens close to the respective work places being used here as display destinations.

  Since the work location is specified for the part name, reel ID, and data to be input thereafter (YES in S24), it is possible to lock the use location of the target scanner to the specified work location, or display destination management information. Refer to and judge. Specifically, if the display management information indicates that the target scanner is available at that work location and that no other scanner is currently in use at that work location, It is determined that the work place can be locked (YES in S25). Then, the display destination management information is updated to indicate that the target scanner is currently in use at the work place (S26).

  If the working location has been identified but the target scanner is not shown to be usable at the working location, or another scanner is shown to be currently in use at the working location In step S34, it is determined that the usage location of the target scanner cannot be locked (NO in S25), an error message is created (S33), and the message is transmitted and displayed on a display screen close to the work location (S34).

  At this time, at the timing when the message is transmitted, a command for playing an answer back sound, which is an example of a dial tone, is transmitted to the target scanner. Then, the operator can hear the answerback sound from the scanner at hand and immediately check the display screen to confirm the message.

  In particular, when an error message is displayed on the display screen, the operator can immediately recognize the content by the answer back sound and deal with the error. Hereinafter, not only an error message but also a message is displayed on the display screen, this answerback sound is sounded, and the description is omitted.

  If the work location is not specified or the usage location of the target scanner can be locked, the following display is performed by executing step S28 and subsequent steps.

  First, when the work place is not specified (NO in S28), a message indicating the determination result in step S22 (if the input data is determined to satisfy the verification condition, the OK message is determined not to satisfy the verification condition) In this case, an NG message) is created (S32), and the created message is transmitted and displayed on the display screen close to each work place recorded as being currently used in step S27 (S34).

  For example, as shown in the display destination management information of FIG. 4, when the scanner S1 is currently in use for the collation of components set in the tables TBL1 and TBL3 of the component mounter M01, another scanner S2 is used. When the operator ID is scanned by starting a new part collation operation, the work location for the new collation operation has not yet been specified, and therefore, among the front work locations where the front scanner S2 can be used. Thus, on all display screens close to the work place where the scanner S1 is not currently used, that is, on the display screen DSP1 on the front side of the component mounters M02 to M04, the result of the determination whether the operator ID satisfies the verification condition is displayed. Is done.

  On the other hand, if the work place is specified (YES in S28), a message representing the determination result in step S22 is created (S30) for the display screen close to the specified work place (YES in S29). The message is transmitted to the display screen for display (S34), and for other display screens (NO in S29), a message indicating that the target scanner is in use at another work place is created (S31). Then, the created message is transmitted and displayed on the display screen (S34).

  For example, as shown in the display destination management information of FIG. 4, when the scanner S1 is currently in use for a collation operation of components set in the tables TBL1 and TBL3 of the component mounter M01, the work location in use is displayed. On the front display screen DSP1 of the nearby component mounter M01, a message indicating the result of the determination as to whether the data acquired from the scanner S1 satisfies the collation condition is displayed, and another display screen, that is, the component mounter A message indicating that the scanner S1 is in use at another work place is displayed on the display screen DSP1 on the front side of each of M02 to M04.

  FIG. 8 is a diagram illustrating an example of a message displayed in the input data processing. This example shows the display contents when it is determined that the input part name satisfies the verification condition in the verification process of the component performed when the component set is confirmed in the component mounter.

  FIG. 8A is an example of display contents on the display screen DSP1 of the component mounter M01 that is a work place where the scanner S1 is currently in use, and an address number for identifying each feeder and its feeder at the top of the screen. The part name of the part to be set is displayed, and a guidance message regarding the scanner operation “part name OK” is displayed at the bottom of the screen.

  FIG. 8B is an example of the lower part of the display contents on the display screen DSP1 of the component mounter M02, and an error message “in use in another machine” is displayed unlike the above-described guidance message.

  Note that FIG. 8 merely shows an example at the time of component set confirmation among the display contents related to the component collation operation. Of course, in other situations, a screen display related to the collation operation of parts is made according to the situation. For example, during mounting production, the type of production board, the number of mounted components, production tact, and the like are displayed. Even when such display is performed, FIG. 8A and FIG. A message related to the component collation work as shown in (B) is displayed.

  Up to this point, the example has been described in which the display destination is managed using the display destination management information that associates in advance the work place where the scanner can be used and the display screen close to the work place. By using such display destination management information, the display destination can be managed in units of component mounting machines, and a display screen close to the work place can be managed as the display destination in consideration of before and after the mounting line.

  That is, of the display screens DSP1 and DSP2 included in the component mounter M01, the data related to the operations of the front scanners S1 and S2 is displayed on the front display screen DSP1, and the data related to the operations of the rear scanners S3 and S4 is Management on the display screen DSP2 on the side. The display screen managed in this way can also be referred to as a display screen close to the position of the scanner.

  In addition to the management of the display destination, the position of the scanner may be specified by detecting a signal from the scanner (scanner position signal), and the data may be displayed on a display screen close to the position of the scanner. . Further, the position of the operator performing the collation work may be detected by, for example, a position signal from an IC tag possessed by the operator, and the data may be displayed on a display screen close to the position of the operator.

<Parts verification processing>
The entire flow of the component verification process performed by the component verification device 10 will be described with a specific example.

First, the barcode used for the component matching operation will be described.
FIG. 9 is a diagram illustrating examples of bar codes of several types scanned by an operator's scanner operation.

  FIG. 9A is an example of a bar code representing a command corresponding to a situation in which component collation is to be performed. Such a barcode is described in a command sheet placed near the position where the barcode scanner is installed, for example, at a position where the operator can always scan. When a situation in which parts collation is to be performed occurs, the operator scans a command corresponding to the situation from the command sheet, so that parts collation by a procedure corresponding to the situation is started.

  FIG. 9B is an example of a bar code representing an operator ID for identifying an operator. Such an operator ID is indicated, for example, on an operator's name tag. Depending on the parts verification procedure, the operator scans such an operator ID shown on his / her name tag in order to record the operator who performed the verification operation.

  FIG. 9C shows an example of a bar code representing the part name, lot name, vendor name, and remaining number regarding the parts stored in the component reel, and the part name, lot name, vendor name, and remaining number. 7 is an example of a bar code representing a reel ID that is reattached at the mounting site.

  The former is a part name, lot name, etc. in the system given by the vendor according to the vendor's definition, and is a barcode already attached to the reel when this part reel is purchased from the vendor (lower part in the figure) Bar code).

  The latter includes the part name in the system managed at the mounting site where the component reel was purchased, and is a unique code for the component reel, so that the component management and production history management can be streamlined. This is a barcode that is printed on-site and affixed to a component reel (upper barcode in the figure).

  The operator scans either the former or the latter barcode according to the part collating procedure.

  Each bar code includes the main content of the data and a code indicating the type of the data, so that the type of data represented by the bar code can be specified from the scanned bar code. It has become.

  Moreover, not only such a bar code but also a two-dimensional code (QR code), a wireless tag, and other readable / writable storage elements may be used to represent and record data handled in the component verification process. Of course.

  FIG. 10 is a flowchart illustrating a specific example of the component matching process performed by the component matching device 10. This flowchart represents the processing procedure in units of work items recognized by the operator. Also, for the sake of brevity, description of processing relating to errors is omitted.

  In the following description, it is assumed that the component collating process is started by the operator scanning the command sheet setup command shown in FIG. When another command, for example, a splicing command is scanned, the component matching process is started according to the procedure according to the splicing work.

  FIG. 11 is a diagram illustrating an example of a collation operation state screen displayed on the display screen of the component mounter specified as the display destination in the component collation processing. From the top in the screen, the work procedure represented by the read work flow data, the check mark indicating the work item completed in the work procedure, the instruction information for the operator, the status of the barcode scanner, and the parts to be verified Information indicating the feeder of the component mounter is displayed.

This collation work status screen may be displayed on the display device of the component collation apparatus 10 itself.
Hereinafter, a specific example of the entire component matching process will be described with reference to the flowchart of FIG.

  When a command representing a situation in which parts matching is to be performed (in this description, as an example, setup) is scanned by the operator, the parts matching apparatus 10 starts a parts matching process according to a work procedure corresponding to the situation.

  When another command, for example, a splicing command is scanned, a component collation process of another work procedure is started. With this configuration, it is possible to perform component verification according to one of the plurality of work procedures that is suitable for the activation factor.

  The component collation apparatus 10 displays a collation work state screen including at least the work flow and the progress in the work flow (see FIG. 11). NO. Parts collation work proceeds in the order of the column numbers. Each column represents a work flow that is alternatively executed. Work items in the same row in different columns represent the same work item or work items that are to be executed alternatively in the same execution order.

  This collation work state screen is displayed on the display screen of the component collation apparatus 10 and also on the display screen of the component mounter specified as described in detail above.

  Further, an operation on the work flow displayed on the display screen of the component mounter may be performed by a button operation of the scanner.

The component verification device 10 first executes “operator ID acquisition” (S01).
A guidance message indicating that it is waiting for an operator ID input is displayed on the collation work status screen. The guidance message may be content that instructs or prompts the operator to input an operator ID. This applies not only to the guidance message “Acquire operator ID” but also to the guidance messages after “Acquire part name”.

  When the scanned data is acquired according to the operation of the operator, it is determined whether or not the type of the data is an operator ID. As described above, this determination can be made using a code representing its own type included in the barcode.

  If the type is an operator ID, a collation condition indicating that the acquired data is appropriate as an operator ID, that is, the number of characters of the acquired data is greater than 0 and less than 31, and the contents are registered as an operator. Judge whether to satisfy the inclusion in the list. These conditions may be combined by AND.

  When this collation condition is satisfied, it is determined that the input is OK, operator ID data is displayed on the collation work status screen, and a check mark indicating operator ID collation OK is displayed in the “operator ID acquisition” column.

  Next, a guidance message indicating that it is waiting for part name input is displayed on the collation work status screen. When the scanned data is acquired according to the operation of the operator, it is determined whether or not the type of the data is a part name. If the type of the input data is not a part name, the part collation apparatus 10 branches the process to “reel ID acquisition” (S02a).

  For this branching, “part name acquisition” (S02) is executed if the type of the input data is a part name, and “reel ID acquisition” (S06) is executed if the type of the input data is a reel ID. . That is, a work flow that can be handled regardless of which part name or reel ID is scanned is defined.

  Thus, for example, when a component name is scanned at a mounting site where reel ID is not managed and a reel ID is scanned at a mounting site where reel ID is managed, it is possible to cope with a single work procedure. Versatility is realized.

  Now, if the type is a part name, the collation condition indicating that the acquired data is appropriate as a part name, that is, the content of the acquired data matches the part name predetermined by the production program. The success or failure of the collation condition such as whether to do is determined.

  If this condition is satisfied, it is determined that the input is OK, and a check mark indicating that part name verification is OK is displayed in the “part name acquisition” completed column of the verification status screen.

Next, “lot name acquisition” is executed (S03).
A guidance message indicating that the system is waiting for lot name input is displayed on the verification work status screen. When the scanned data is acquired according to the operation of the operator, it is determined whether or not the type of the data is a lot name.

  This “lot name acquisition” may be omitted. In this case, if the type of the input data is not a lot name, the component verification apparatus 10 branches the process to “obtain vendor name” (S03a).

  For this branching, “lot name acquisition” (S03) is executed if the type of input data is a lot name, and “vendor name acquisition” (S04) is executed if the type of input data is a vendor name. . In other words, a work flow is defined that can be handled regardless of whether a lot name or a vendor name is scanned.

  As a result, even when the lot name is not assigned to the component reel by the vendor, it is possible to eliminate the inconvenience that the lot name verification is not OK and it is not possible to proceed to the next work item.

  If the type of the acquired data is a lot name, for example, it is determined whether or not the content of the acquired data matches the lot name before replacement as a verification condition. . As a result, it is possible to prevent a mistake that the operator has just removed the component reel that has just been removed from the component mounter.

  If the collation is OK, a check mark indicating a lot name check OK is displayed in the “lot name acquisition” column of the collation work status screen.

Next, “vendor name acquisition” is executed (S04).
Next, “remaining number acquisition” is executed (S05). The remaining number matching condition is OK if the remaining number is equal to or greater than a predetermined value. As a result, it is possible to eliminate the problem that the production starts with a reel whose remaining number of parts is less than a predetermined value, and the parts are immediately cut out.

Next, “read feeder status” is executed.
When branching from the conditional branch S02a to “reel ID acquisition”, “reel ID acquisition” is executed (S06), and then the processing is merged.

  In the case of branching to “acquire reel ID”, the operator does not go through S02 to S05, so the operator has no opportunity to scan the part name, lot name, vendor name, and remaining number. Therefore, equivalent information included in the reel ID is substituted for these pieces of information.

  Since input data is not acquired in “reader status reading”, a guidance message indicating input waiting is not displayed unlike conventional work items. Instead, a message indicating that the feeder status is being confirmed is displayed on the verification work status screen. Then, a command is sent to the component mounter to inquire about the status of the feeder to which the component reel should be hung. If a response is returned indicating that the feeder is in a normal state where the component reel can be hung, it is determined that the feeder confirmation is OK. A check mark indicating feeder status confirmation OK is displayed in the “read feeder status read” column of the work status screen (S07).

  Next, in the “feeder instruction”, a message indicating that the LED is lit is displayed on the collation work status screen, and then an LED lighting request for turning on the feeder LED is transmitted to the component mounter. If a response indicating that the LED is properly lit is returned, it is determined that the LED is lit OK, and a check mark indicating that the LED is lit OK is displayed in the “Feeder Instruction” field on the collation work status screen.

  Thus, the operator can be instructed reliably by the lighting of the LED on the feeder on which the component reel is to be hung (S08).

Next, “acquisition event acquisition” is executed (S09).
A guidance message indicating that it is waiting for the confirmation button operation is displayed on the collation work status screen. This confirmation button is a button on the operation panel of the feeder.

  When the operator presses the button, event information indicating that the confirmation button has been operated is received from the component mounter. When this event information is received, it is determined that the confirmation button is OK, and a check mark indicating the confirmation button OK is displayed in the “confirmation event acquisition” completed column of the collation work status screen.

  Thus, it is possible to reliably proceed to the next work item after waiting for a cue operation indicating completion of replacement of the component reels from the operator.

Next, “data writing” is executed (S10).
After a message indicating that data is being written is displayed on the collation work status screen, a data write request is transmitted to the component mounter 20, and a data write response is received from the component mounter 20. Here, the data writing means writing the part name, lot name, vendor name, and remaining number of the part after replacement into the memory of the feeder whose part reel has been replaced.

  The memory of the feeder can be accessed from the control unit of the component mounter, and can store information related to components mounted on the substrate in units of substrates. Such information is used for production traceability.

  Further, by writing the remaining number in the memory, every time the component mounter takes out the component from the feeder and mounts it, the remaining number is subtracted to update the remaining component number, which is used for the advance notice of component shortage. The subtracted remaining number is managed for each component reel (reel ID) by the host server.

  When the reel ID is acquired in S06, as described above, information equivalent to the part name, lot name, vendor name, and remaining number included in the reel ID is written in the memory.

  When the content of the response indicates that the data has been normally written in the memory, it is determined that the data has been successfully written, and a check mark indicating that the data has been successfully written is displayed in the “DATA WRITING” completed column on the collation work status screen. .

  Finally, in “completion sound output”, a message indicating that the completion sound is being output is displayed on the collation work status screen, and then a completion sound output request is transmitted to the barcode scanners 41 and 42, and the barcode scanner 41 , 42 receives a completion sound output response.

  When the content of the response indicates that the completion sound has been output normally, it is determined that the completion sound output is OK, and a check mark indicating the completion sound output OK is displayed in the “completed sound output” completed column of the collation work status screen. indicate.

  Then, a collation completion message indicating that all the series of work items have been completed is displayed on the collation work status screen.

  By displaying such a collation screen on a display screen close to the scanner of the component mounter, it is possible to quickly and accurately grasp the progress of the component collation from the mounting line.

<Display of the screen contents of the parts verification device>
The component verification device 10 may display its own screen content on the display screen of the component mounter. If it does so, the same content can be displayed on a plurality of display screens of the display screens of the component verification device 10 and the component mounter. Thereby, the operator can conveniently confirm the teaching content of the component verification device on either the display screen of the component verification device 10 or the display screen of the component mounter.

  In addition, when the component mounting system includes an information display terminal device other than the display screen of the component mounter, and the information display terminal device is near the place where the component collation work is performed, the information display terminal device The screen content of the component verification device 10 may be displayed on the screen. As a result, the operator can check the original display contents of the component mounting machine as shown in FIG. The screen content of the verification device 10 can be confirmed.

  FIG. 12 is a diagram illustrating an example of the screen content of the component verification apparatus. This example shows an example of a component list screen that displays a list of components across a plurality of mounting lines.

  The component list screen displays component management information, such as which component mounting machine is located at which position (address) and how many remain, for each component used on the mounting line. The

  The component list screen is displayed not only on the display screen of the component verification device but also on the display device 40 in the preparation area away from the mounting line, and is referred to in preparation work across a plurality of mounting lines.

  By displaying such a component list screen on a display screen close to the scanner of the component mounting machine, it becomes possible to quickly and accurately grasp the status of the component from within the mounting line.

  Since both the component list screen and the above-described collation work screen present a relatively large amount of data, it is desirable to switch and display the original screen of the component mounter according to the display switching operation performed by the operator. .

  This switching may be performed in response to an operator operation on operation buttons and operation switches provided on the display screen of the component mounter. For example, although the contents at the time of component setup as shown in FIG. 8A are normally displayed on the display screen of the component mounter, the operation screen of the work flow in FIG. 11 is displayed according to the operation on the operation buttons. It can be displayed by switching to the contents. The display content of the display screen of any component mounter can be switched to the same display content as the display screen of the component verification device 10 by performing the above operation.

<Application to maintenance work>
Up to this point, the example in which the data related to the scanner operation is preferentially displayed on the display screen close to the place where the part collation operation is performed has been described. As a modified example, when one of a plurality of component mounters is maintained, data related to the maintenance work may be displayed on the display screen of the component mounter close to the component mounter on which the maintenance work is performed.

  For example, specifically, maintenance information of a feeder may be read by a portable terminal from a memory provided in the feeder, and the maintenance information may be displayed on a display screen close to a table in which the feeder is set.

  In addition to the feeder, maintenance information of other devices such as a head and a nozzle may be read from a memory provided in the device and displayed on a display screen close to the device (close to a portable input device).

<Summary>
As described above, according to the component verification method and the component verification apparatus of the present invention, data related to operations performed on the handy scanner with respect to component verification is stored in the component mounting on which the assembly of components is to be set. Since the image is displayed on the display screen of the machine, it is possible to perform a component collation operation with good work efficiency using a scanner having no display screen.

  The component verification method of the present invention can be used in a component mounting system including a component mounter that mounts a verified component on a substrate.
