Description

  The present invention relates to a component verification method, a component information management method, a component mounting method, and a component mounting method for verifying whether or not a component arranged in a component supply unit that supplies a component to be mounted by a component mounter is appropriate. In particular, the present invention relates to a component verification apparatus, a component mounter, and a program, and more particularly, to a technique that facilitates changing a procedure of component verification work.

  Conventionally, as an example of component verification in component mounting, when a component shortage occurs, the barcodes of the replacement target component that was out of component and the newly supplied replacement component are both read according to the operation by the operator. A technique is known in which parts are collated based on whether or not the part product numbers indicated by the bar codes match (for example, see Patent Document 1).

  The actual part collation work at the site where the component is mounted is not limited to this example, and there are various types of procedures, and the procedure often varies greatly depending on the mounting site.

  For example, in one mounting site, an operator performs detailed component verification by reading a bar code representing the part name, lot name, and vendor name of each part to be replaced and replacement parts, whereas in another mounting site, In some cases, simple part verification may be performed by omitting reading of a bar code representing a lot name and a vendor name.

  Also, for example, at one mounting site, parts verification is performed by reading a bar code representing a part name attached to a component reel from a component vendor, while at another mounting site, the part name is indicated. Thus, component verification may be performed by reading a barcode that has been reattached at the mounting site.

And the part collation procedure may change according to technological progress.
Therefore, it is desirable that the component collation method and the component collation apparatus used for general purposes are configured so as to cope with various work procedures and to flexibly change the work procedures.
JP 2000-68697 A

  However, Patent Document 1 does not disclose a technique for collating parts corresponding to a plurality of work procedures and making the work procedures easy to change.

  The present invention has been made in view of such circumstances, and provides a component verification method and a component verification apparatus that can cope with various work procedures in component verification and can change the work procedure flexibly. With the goal.

In order to achieve the above object, a component verification method according to the present invention is a component verification that uses a computer to verify whether or not a component placed in a component supply unit that supplies components to be mounted by a component mounter is appropriate. A method for recording work flow data indicating an order among a plurality of work items included in a component collation work, a change step for changing the recorded work flow data, and a work flow after the change An execution step of sequentially selecting the plurality of work items according to the order indicated by the data, and executing a process related to the selected work items.

  Here, in the recording step, a collation condition indicating the success or failure of each work is recorded for each of the plurality of work items, and in the execution step, the success or failure of the collation conditions is determined for each work item. The collation result in the component collation work may be displayed.

  Further, in the recording step, for the work item for acquiring the lot information of the part, a verification condition indicating a verification error is recorded by the fact that the acquired lot information and the lot information of the part before the replacement match, In the execution step, it is determined whether or not the acquired lot information and the lot information of the part before replacement match, and if they match, an error message indicating that the verification has failed is displayed. Also good.

  According to this configuration, only the work flow data and the collation condition data are changed, the work procedure is changed in units of work items, and the work success / failure judgment condition is changed without changing the main program. Can do.

  In making these changes, programming expertise is not required because there is no need to change the main program. The work flow data and collation condition data can be easily set and changed as long as there is business knowledge about parts collation.

  Thereby, while respond | corresponding to various work procedures in components collation, a work procedure can be changed flexibly.

  Also, in the recording step, a plurality of workflow data is recorded corresponding to the different activation factors of the execution step, and in the execution step, the workflow data is recorded according to the order indicated by the workflow data corresponding to the activation factor of the execution step. A plurality of work items may be sequentially selected, and processing related to the selected work items may be executed.

According to this configuration, it is possible to apply different work procedures according to activation factors.
The component verification method further includes a change step of changing the workflow data, and in the execution step, the plurality of work items are sequentially selected according to an order indicated by the changed workflow data, You may perform the process regarding the selected work item.

According to this configuration, the work procedure can be flexibly changed following the change of the work procedure.
Further, in the execution step, when executing a process related to each of the plurality of work items, a work progress indicating a work item to be executed may be displayed, and one of the plurality of work items is: It is a feeder instruction work for instructing a feeder of the component mounter on which a component to be collated is to be placed, and when the feeder instruction work is selected in the execution step, a feeder instruction indicating the feeder may be displayed. .

  Further, one of the plurality of work items is a data acquisition work for acquiring input data, and in the recording step, further records a request type that is a type of data to be acquired in the data acquisition work, When the data acquisition operation is selected in the execution step, input data may be acquired from an input device operated by an operator after displaying a guidance requesting the input data of the request type.

  According to this configuration, the collation operator can work after reliably recognizing the status of the collation work, the feeder to be operated, and the data to be input, which is useful for improving the efficiency and reliability of the collation work. .

  The recording step further records alternative data indicating alternative data acquisition work to be executed alternatively in the same order as the data acquisition work, and in the control step, the type of the acquired input data Is not the request type, the alternative data acquisition operation indicated by the alternative data may be selected to continue the processing.

  Here, the data acquisition operation and the alternative data acquisition operation are operation items for acquiring first type input data and second type input data read from a component reel, respectively, and are acquired in the execution step. If the type of the input data is the first type, a process related to the work item after the data acquisition operation is executed. If the type of the acquired input data is the second type, the alternative data acquisition operation You may perform the process regarding the subsequent work item.

  The first type of input data is represented by a first bar code provided by the component reel vendor, and the second type of input data is provided by a second bar assigned to the component reel at the mounting site. When the acquired input data is expressed by the first barcode in the execution step, the processing related to the work item after the data acquisition operation is executed, and the acquired input data Is represented by the second bar code, processing relating to work items after the substitute data acquisition work may be executed.

  According to this configuration, it is possible to set a plurality of work items to be executed alternatively using the alternative data, and thus it is possible to easily express a relatively complicated work procedure including a branch of the work flow.

  In particular, when data of a type different from the desired type is acquired in the data acquisition work, the execution of the set alternative data acquisition work improves the flexibility of the verification work and improves the efficiency of the verification work Contribute to.

  Further, in the recording step, whether or not the data acquisition operation is omitted is recorded, and in the control step, if the type of the acquired input data is not the request type, the data acquisition operation is recorded as omissible. If so, a work item subsequent to the data acquisition work may be selected to continue the process.

  Here, the data acquisition operation and the subsequent operation item are operation items for acquiring the first type data and the second type data read from the component reel, respectively, and the first type data can be omitted. Yes, in the execution step, when the type of the acquired input data is the second type, the process related to the data acquisition work may be omitted and the process related to the subsequent work item may be executed.

  According to this configuration, an omissible work item can be set using the omissibility, so that a relatively complicated work procedure including skipping of the work item can be expressed easily.

  In particular, when data of a type different from the desired type is acquired in the data acquisition task set as optional, the subsequent work item is executed, which improves the flexibility of the verification operation and Contributes to improved efficiency.

  The present invention can be realized not only as such a component verification method, but also as a component information management method, a component mounting method, a component verification apparatus, a component mounter, a program, and a program for executing these methods. It can also be realized as a storage medium for storing.

  According to the component collation method of the present invention, the work flow data indicating the order between the plurality of work items included in the component collation work is recorded, and the plurality of work items are sequentially selected according to the order indicated by the work flow data. Since the process related to the selected work item is executed, the work procedure can be changed in units of work items without changing the main program only by changing the work flow data.

  In making these changes, programming expertise is not required because there is no need to change the main program. The work flow data can be easily set and changed as long as there is business knowledge about parts collation.

  As a result, various work procedures can be dealt with in component verification, and the work procedures can be flexibly changed.

  Further, not only the work flow data but also the collation conditions can be changed, so that it is possible to realize component collation that closely corresponds to the request from the mounting site.

The compound condition 136 represents one of an OR operation, an AND operation, and an XOR operation as an operation for combining a simple condition with a compound condition.

  Hereinafter, the processing for editing and recording such work flow data and collation condition data will be described in detail, and then the specifics of the part collation processing performed corresponding to the work flow data in FIG. 5 and the collation condition data in FIG. An example will be described in detail.

<Workflow recording process>
A workflow recording process performed by the workflow recording unit 11 will be described.

FIG. 7 is a flowchart illustrating an example of the workflow recording process.
FIG. 8 is a diagram illustrating an example of a workflow setting screen displayed on the input / output unit 15 in the workflow recording process.

  When the activation factor is selected from the activation factor pull-down menu on the left side of the screen by the setting operator (S101), the workflow recording unit 11 records the workflow related to the selected activation factor in the workflow data storage unit 12. For example, the workflow data is read out and displayed in a table format on the right side of the screen (S102).

  The display in FIG. 8 represents the contents of the workflow data in FIG. 5 as an example. The work items S02 and S06 to be executed alternatively in the same order are displayed in the same row in different columns, and the work items to be executed in common before and after those work items overlap in each column. Displayed.

  When the setting operator operates the work item addition button on the left side of the screen, the work flow recording unit 11 further receives the item number and the content of the work item from the setting operator, and adds the work item having the received content to the table. . When the work item deletion button is operated, the work item is deleted from the table. When the omissible check box is operated, whether or not the work item is omissible is set in the contents of the check box (S103).

  When the collation condition setting button is operated, the collation condition setting screen is opened, and the collation condition for the work item is received from the setting operator (S104).

  FIG. 9 is a diagram illustrating an example of a collation condition setting screen that is opened when the collation condition setting button is operated.

  The display in FIG. 9 shows the contents of the collation condition data in FIG. 6 as an example. In the upper part of the screen, individual compound conditions representing the matching conditions are shown.

  When the workflow recording unit 11 receives from the setting operator the type of data to be input in this work item in the input data type pull-down menu in the middle of the screen, the workflow recording unit 11 determines the judgment item field, comparison item field, and comparison condition field in the middle of the screen. The contents of the simple condition relating to the input data are accepted, and further, the contents of processing when the matching condition is satisfied are accepted from the pull-down menu at the bottom of the screen.

  Further, when one of the radio buttons for specifying a condition for combining the simple condition in the middle of the screen with the composite condition is selected by the setting operator and then the condition addition button is operated, the workflow recording unit 11 has already been received. Combines a simple condition with a specified condition into a compound condition. When the condition delete button is operated, the combined condition combination is canceled.

  When the acceptance of the collation condition is completed, the collation condition setting screen is closed and the process returns to the work flow setting screen of FIG.

  The workflow recording unit 11 adds a new column for setting a workflow to the table when the setting operator operates the workflow addition button in the lower left part of the screen. This column is added, for example, by duplicating an existing column. In the added column, when the work item is changed by the setting operator, the work item is set as an alternative item. When the workflow deletion button is operated, one column is deleted from the table. (S105).

  Then, the workflow recording unit 11 continues editing the workflow data by repeating S103 to S105 until the OK button or the cancel button is operated (YES in S106), and is edited when the OK button is operated. The work flow data is recorded in the work flow data storage unit 12 (S107).

<Parts verification processing>
Next, the component verification process performed by the component verification unit 14 will be described.

First, the barcode used in the component matching process will be described.
FIG. 11 is a diagram illustrating examples of bar codes of several types scanned by an operator's scanner operation.

  FIG. 11A 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. 11B 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. 11C shows an example of a bar code representing a part name, a lot name, a vendor name, and the remaining number regarding the parts stored in the component reel, and represents the part name, the lot name, the vendor name, and the 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 showing a specific example of the component collation processing performed by the component collation apparatus corresponding to the work flow data of FIG. 5 and the collation condition data of FIG. 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. 12 is a diagram illustrating an example of a collation work state screen displayed on the input / output unit 15 and the display device 30. 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.

  FIG. 13 is a sequence chart illustrating an example of communication contents in the component matching process. This sequence chart shows an example of data communicated between the component verification device 10, the component mounter 20, the display device 30, and the barcode scanners 41 and 42.

  Hereinafter, the detailed processing contents including the display of the collation work state screen shown in FIG. 12 and the communication data exchange shown in FIG. 13 will be described with reference to the flowchart of FIG.

  When a command (in this description, as an example, setup) representing a situation in which parts are to be collated is scanned by an operator, the collation processing unit 14 obtains workflow data and collation condition data having the situation as an activation factor, respectively. Read from the work flow data storage unit 12 and the verification condition data storage unit 13 (S01a).

  When the component collation process is activated by scanning another command, for example, a splicing command, workflow data and collation condition data (both not shown) whose activation factor is splicing are read. With this configuration, it is possible to perform component verification by selectively using one of the plurality of procedures according to the activation factor.

  The collation processing unit 14 displays a collation work status screen including at least the work procedure indicated by the read work flow data and the progress in the work procedure on the input / output unit 15 and the display device 30 (see FIG. 12). reference).

  The collation processing unit 14 first selects the work item “acquire operator ID” of the item number S01. Then, processing is performed according to the collation process execution program and collation condition data relating to the selected work item (S01).

  Since the input data type (see FIG. 9) in the collation condition data corresponding to the work item of S01 is the operator ID, the operator ID waits for the operator ID input on the display screen of the component mounter 20 and the collation work status screen of the display device 30. A guidance message indicating that there is a message is displayed. This guidance message may be a content that instructs or prompts the operator to input an operator ID.

  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, the acquired data is the collation condition represented by the collation condition data, that is, the number of characters of the acquired data is greater than 0 and smaller than 31, and the contents are included in the operator registration list. Judge whether or not to satisfy Compound conditions may be combined by AND.

  If this condition is satisfied, it is determined that the input is OK, the operator ID data is displayed on the collation work status screen of the display device 30, and a check mark indicating operator ID collation OK is displayed in the “operator ID acquisition” completed column. Display (see data flow in FIG. 13).

  Next, the work item “part name acquisition” of the item number S02 indicated in the next item of the work flow data is selected. Then, processing is performed according to the collation process execution program and collation condition data regarding the selected work item (S02). In addition, specific illustration of the collation condition data after the item number S02 is omitted.

  Since the input data type in the collation condition data corresponding to the work item of S02 is a part name, 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.

  Here, it should be noted that the substitute item S06 is set in the work flow data with the item number S02. For this setting, when the type of the input data is not the part name, the collation processing unit 14 selects “Reel ID acquisition” with the item number S06 and branches the process (S02a). That is, in the work item of S02, 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 that does not manage the reel ID, and a reel ID is scanned at a mounting site that manages the reel ID, it becomes possible to deal with a single work flow data. High versatility is realized.

  If the type of the acquired data is a part name, the matching condition indicated by the matching condition data (not shown) of the work item S02 is determined. This condition is a condition such as whether or not the content of the acquired data matches the part name predetermined by the production program.

  If this condition is satisfied, it is determined that the input is OK, and a check mark indicating the part name verification OK is displayed in the “part name acquisition” completed column of the verification operation status screen of the display device 30.

  Next, the work item “lot name acquisition” of the item number S03 indicated in the next item of the work flow data is selected. Then, processing is performed in accordance with the collation process execution program and collation condition data relating to the selected work item (S03).

  Since the input data type in the collation condition data corresponding to the work item of S03 is a lot name, a guidance message indicating that a lot name is awaiting 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 lot name.

  Here, it should be noted that omission is set to YES in the work flow data with the item number S03. For this setting, when the type of the input data is not a lot name, the collation processing unit 14 selects “vendor name acquisition” in the next item S04 and branches the process (S03a). That is, in the work item of S03, a work flow that can handle both when the lot name is scanned and when the next vendor name is scanned is defined.

  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 of the display device 30.

  Next, the work item “obtain vendor name” of the item number S04 indicated in the next item of the workflow data is selected, and the same processing is performed (S04).

  Next, the work item “remaining number acquisition” of the item number S05 indicated in the next item of the work flow data is selected, and the same processing is performed (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, the work item “read feeder status” of the item number S07 indicated in the next item of the work flow data is selected.

  It should be noted that when processing branches to the work item “acquire reel ID” with the item number S06 in processing S02a, the same processing is performed (S06). After that, since the next item of the work flow data is S07, the work item “read feeder status”. And the process merges. 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 the request type of the work item “read feeder status” is indicated as “None”, the guidance message indicating the waiting for input is not displayed unlike the work item so far. Instead, a message indicating that the feeder status is being confirmed is displayed on the display device 30. Then, a command for inquiring about the status of the feeder to which the component reel should be hung is transmitted to the component mounting machine 20, and a feeder status inquiry response is received from the component mounting machine 20.

  When the content of the response indicates that the feeder is in a normal state where the parts reel can be hung, it is determined that the feeder is confirmed OK, and the feeder is displayed in the “Feeder status read” field on the collation operation status screen of the display device 30. A check mark indicating OK is displayed.

  Next, in the work item “feeder instruction”, after a message indicating that the LED is being lit is displayed on the display device 30, an LED lighting request for turning on the LED of the feeder is transmitted to the component mounter 20, An LED lighting response is received from the component mounter 20.

  When the content of the response indicates that the LED is correctly lit, 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” completed column of the collation work status screen of the display device 30. .

  Thereby, it is possible to reliably instruct the operator of the feeder on which the component reel is to be hung by lighting the LED.

  Next, in the work item “acquisition of confirmation event”, since the input data type in the collation condition data corresponding to this work item is a confirmation button, the display screen of the component mounter 20 and the collation work status screen of the display device 30 are displayed. Displays a guidance message indicating that it is waiting for a confirmation button operation. 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 20. 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 of the display device 30.

  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, in the work item “data write”, a message indicating that data is being written is displayed on the display device 30, then a data write request is transmitted to the component mounter 20, and a data write response is sent from the component mounter 20. Receive. 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 written, and a check is made to indicate that the data has been written in the “DATA WRITING” column on the collation work status screen of the display device 30. Display the mark.

  Finally, in the work item “completion sound output”, a message indicating that the completion sound is being output is displayed on the display device 30, and then a completion sound output request is transmitted to the barcode scanners 41 and 42. The completion sound output response is received from 41, 42.

  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 the completion sound output OK is displayed in the “Completed sound output” column of the collation work status screen of the display device 30. A check mark is displayed.

  Then, a collation completion message indicating that all the series of work items have been completed is displayed on the display screen of the component mounter 20 and the display device 30.

<Change of parts verification process by changing work flow data>
Next, a description will be given of a change in the component collation process by changing the work flow data.

  First, as an example of changing the work item, it is considered that the work item “operator ID acquisition” is designated as omissible on the work flow setting screen of FIG. This change is assumed to correspond to a mounting site where simple component verification is performed without scanning the operator ID.

  The collation processing unit 14 that operates according to the changed work flow data performs the same type of processing as the input data type determination S03a performed before the lot name acquisition S03 before the operator ID acquisition S01. .

  As a result, the operator ID acquisition S01 is skipped even if the part name or the reel ID is first scanned without scanning the operator ID, and then the part name acquisition S02 or the input data type determination S02a or The reel ID acquisition S06 is changed to be executed. In this way, flexible component verification is realized in which all of the operator ID, part name, and reel ID are accepted first.

  Further, as an example of adding a work flow, adding a work item “second reel ID acquisition” to be executed alternatively in the same order as “reel ID acquisition” on the work flow setting screen of FIG. Think. This addition assumes that it corresponds to two mounting sites that manage reel IDs of different systems.

  The collation processing unit 14 that operates according to the changed work flow data executes the same type of processing as the input data type determination S02a performed before the part name acquisition S02 before the reel ID acquisition S06, and the input data Depending on the type, the process branches to the added second reel ID acquisition process.

  As a result, even if any of the part name, reel ID, or second reel ID is scanned after the operator ID, an appropriate one of parts name acquisition S02, reel ID acquisition S06, and second reel ID acquisition is appropriate. It is changed so that one is executed. In this way, flexible component verification that can be adapted to various mounting site situations is realized.

  Similarly, when the collation condition data is changed, the collation processing unit 14 operates according to the changed collation condition data, so that the collation condition can be easily changed to the component collation process.

<Summary>
As described above, according to the component collation method and the component collation apparatus of the present invention, the work flow data indicating the order among a plurality of work items included in the component collation work is recorded and indicated by the work flow data. The plurality of work items are sequentially selected according to the order, and processing relating to the selected work item is executed.

  According to this configuration, the work procedure can be changed in units of work items without changing the main program only by changing the work flow data.

  The same applies to the matching condition indicating whether or not the data acquired in the work item for acquiring the data is appropriate, and the data can be acquired without changing the main program simply by changing the matching condition data. The judgment condition as to whether or not the data to be processed is appropriate can be changed.

  In making these changes, programming expertise is not required because there is no need to change the main program. As shown as an example, the work flow data and the collation condition data can be set and changed from the graphical user interface screen. Therefore, setting and changing can be easily performed as long as there is business knowledge about component collation.

  In addition, by representing work item substitution or omission using work flow data, relatively complicated work procedures including work flow branching and work item skipping can be easily expressed.

  For these reasons, by using the component verification method of the present invention, it is possible to cope with various work procedures in component verification and to change the work procedures flexibly.

  The component verification method of the present invention can be used in a component mounting system including a component mounter.
