Description

The techniques disclosed herein relate to device for changing data for component mounting, change programs, and surface mounters.

Conventionally, a surface mounter has been known in which a component supplied via a component supply tape or a component tray is held by a mounting head and mounted on a workpiece such as a printed circuit board. As the mounting head, for example, one that attracts a component by negative pressure, one that sandwiches a component by chucking, and the like are known.

Generally, surface mounters operate based on component mounting data. The data for component mounting is sometimes called a mounting program. For example, when the mounting head attracts components by negative pressure, the component mounting data includes the component identification code of the component to be mounted on the workpiece, mounting order, mounting coordinates, mounting angle, data representing the component shape, and suction height. , Adsorption time, adsorption speed, and other data are included.

The content of the data representing the part shape differs depending on the type of part. For example, in the case of a lead component having a lead (SOP: Small Outline Package, QFP: Quad Flat Package, etc.), the data representing the component shape includes the number of leads, the lead length, the lead width, and the like. In the case of a rectangular parallelepiped or cubic chip component (resistor, etc.), the data representing the component shape includes data such as the length, width, and height of the component. The suction height is the vertical position of the mounting head when the component is sucked by the mounting head. The suction time is the time from when the mounting head descends to the suction height to when it starts to rise. The suction speed is the descending speed of the mounting head when sucking parts.

The data for component mounting is created by the optimization program. The optimization program is a program that optimizes the mounting order of parts so that the mounting time when mounting a plurality of parts on one work is as short as possible. Generally, the operator of the surface mounter can change the data contained in the component mounting data created by the optimization program.

However, if the data is changed, an implementation error may occur due to the change. For example, in general, a surface mounter takes an image of a component attracted to a mounting head with a camera, recognizes the component shape, and determines the quality of the component shape by comparing it with data representing the component shape. Therefore, when the data representing the part shape is changed, the frequency of determining that the part shape is defective may increase due to the inappropriate data after the change. Alternatively, if the adsorption height or adsorption time is changed, the changed adsorption height or adsorption time is inappropriate, which makes it difficult for the parts to be adsorbed, which may increase the frequency of adsorption errors.

For this reason, conventionally, when a mounting error of the surface mounter occurs after the component mounting data is changed, the component mounting data is returned to the state before the change (see, for example, Patent Document 1). Specifically, in Patent Document 1, it is determined whether or not the work result of the component mounting device after the component mounting data is changed satisfies a predetermined condition (adsorption rate, etc.), and if not, it is not satisfied. It is described that the data for component mounting before the change is automatically restored.

Japanese Patent No. 6248286

The cause of the mounting error is not necessarily the change in the component mounting data, but it may also be the malfunction of the components that make up the surface mounter. For example, in the case of a suction error, a suction error may occur due to a malfunction of a component such as a mounting head or an air supply device that supplies negative pressure. If the cause is a malfunction of a component, the mounting error cannot be resolved even if the component mounting data is returned before the change.

Therefore, the operator needs to determine whether the cause of the mounting error is a change in the component mounting data or a malfunction of the components constituting the surface mounter. However, since it takes time to isolate this, it is difficult to recover from the mounting error in a short time.

This specification discloses a technique that is likely to reduce the time required for recovery from an implementation error.

(1) The changing device disclosed in the present specification is a component mounting data changing device including a plurality of data for controlling the operation of a surface mounter for mounting a component on a work, and is a display unit. And a processing unit, the processing unit displays on the display unit the first change process for accepting the change of the data and the data changed in the past by the first change process so as to be identifiable. The first display process to be performed is executed.

When an implementation error occurs, if the data that can cause the implementation error has been changed in the past, it is suspected that the implementation error has occurred due to improper changes in the data. On the contrary, if the data that can cause the mounting error has not been changed in the past, it is suspected that the components of the surface mounter are malfunctioning.

According to the above-mentioned changing device, when a mounting error occurs, it becomes easy for the operator to grasp whether or not the data that can cause the mounting error has been changed in the past. Therefore, when a mounting error occurs, the operator grasps whether or not the data that can cause the mounting error has been changed in the past, and if it has not been changed, priority is given to the malfunction of the component. By investigating and investigating the component mounting data with priority when it is changed, it is highly possible that the cause of the mounting error can be quickly investigated. Therefore, according to the above-mentioned changing device, there is a high possibility that the time required for recovery from the mounting error can be shortened.

(2) In the first display process, the processing unit may change the display form of the data according to the number of times the data is changed.

The more frequently changed data, the more likely it is to cause an implementation error. This is because a large number of changes means that the data has caused many implementation errors in the past, and each time an implementation error occurs, the operator may have changed the data in order to eliminate the implementation error. Because.
According to the above-mentioned changing device, it becomes easy for the operator to grasp the data having a large number of changes. In other words, it makes it easier for the operator to understand the data that is likely to be the cause of the implementation error.

(3) The component mounting data includes component identification data for identifying the component and detailed data related to the component, and the processing unit uses the component identification data whose detailed data has been changed in the past. A second display process for identifiable display on the display unit may be executed.

According to the above-mentioned changing device, when a component mounting error occurs, it becomes easy for the operator to grasp whether or not the detailed data of the component has been changed in the past. In other words, it makes it easier for the operator to know if a change in detailed data may be the cause of an implementation error.

(4) In the second display process, the processing unit may change the display form of the component identification data according to the number of changes of the detailed data.

According to the above-mentioned changing device, it becomes easy for the operator to grasp the parts whose detailed data is frequently changed. In other words, it makes it easier for the operator to know if a change in detailed data is likely to be the cause of the implementation error.

(5) The processing unit may start counting the number of changes in the data when a predetermined condition is satisfied.

When mounting new components, the data may change frequently to tune the mounting behavior. If the change in that case is also included in the number of changes, it becomes difficult for the operator to identify the data that is the cause of the implementation error when the implementation error actually occurs.
According to the above change device, for example, the number of data changes is not counted until tuning is completed, and the count is started when the condition that tuning is completed (an example of a predetermined condition) is satisfied. It is possible to reduce the possibility that it will be difficult for the operator to identify the data that is the cause of the error.

(6) When the processing unit executes the first display processing after the data that may cause the mounting error has been changed in the past when the mounting error of the component occurs. , The data that has been changed in the past among the data that may cause the implementation error may be displayed in an identifiable manner.

According to the above-mentioned changing device, it becomes easier for the operator to grasp the data that may have caused the mounting error, so that it is highly possible that the time required for recovery from the mounting error can be shortened.

(7) When a mounting error of the component occurs, the processing unit subsequently changes the detailed data that may cause the mounting error among the detailed data related to the component in the past. When executing the second display process, the component identification data of the component may be identifiablely displayed.

According to the above-mentioned changing device, when a component mounting error occurs, it becomes easier for the operator to grasp whether or not changing the detailed data about the component may be the cause of the mounting error. It is more likely that the time required to recover from an implementation error can be reduced.

(8) When a mounting error of the component occurs, the processing unit displays at least one of the past mounting error occurrence history of the component and the change history of the detailed data related to the component on the display unit. History display processing to be performed may be executed.

According to the above-mentioned change device, the operator can easily return to the data when the implementation error did not occur, for example, by referring to the change history of the data. In addition, the operator can easily return to the data before the implementation error occurs by referring to the implementation error occurrence history. Therefore, there is a high possibility that the implementation error can be recovered in a short time.

(9) The processing unit displays at least the change history of the detailed data in the history display process, and selects one of the change history from one or more of the change history displayed by the history display process. The history selection process for accepting the above and the rollback process for rolling back the detailed data corresponding to the change history selected in the history selection process to the data before the change in the selected change history are executed. You may.

According to the above-mentioned changing device, the work efficiency of the work of returning to the data before the mounting error occurs is improved. Therefore, there is a high possibility that the time required for recovery from an implementation error can be shortened.

(10) When a mounting error of the component occurs, the processing unit displays a candidate display process for displaying correction candidates of the data that may cause the mounting error on the display unit, and a candidate display process. The candidate selection process that accepts the selection of any of the modification candidates from the one or more modification candidates, and the data corresponding to the modification candidate selected in the candidate selection process are subjected to the selected modification. A second change process for changing to a candidate may be executed.

According to the above-mentioned change device, the operator can easily change the data so that the mounting error does not occur. Therefore, the work efficiency of the work is improved, and there is a high possibility that the time required for recovery from the mounting error can be shortened.

(11) In the candidate display process, the processing unit may display the correction candidate based on the past change history of the data.

The change history contains at least the data before the change. It is more desirable that the change history includes the changed data and the date and time of the change.
According to the above-mentioned change device, it is possible to display correction candidates with a high possibility that an implementation error does not occur based on the past change history of data.

(12) The change program disclosed in the present specification is a change program for component mounting data including a plurality of data for controlling the operation of a surface mounter for mounting a component on a work, and the data is described above. The computer is made to execute the first change process of accepting the change of the above and the first display process of displaying the data changed by the first change process in the past on the display unit in an identifiable manner.

With the above changes, it is likely that the time required to recover from an implementation error can be reduced.

(2) Component mounting data The component mounting data will be described with reference to FIGS. 4 and 5. Any data structure can be adopted as the data structure of the component mounting data, but here, one mounting information table 40 (see FIG. 4) and each type of component E (chip component, lead component, etc.) are provided. An example will be described in which the configuration is composed of one or more component detail tables 41 (see FIG. 5).

The implementation information table 40 will be described with reference to FIG. The mounting information table 40 is a table in which the component E mounted on the printed circuit board P is registered. Each row of the mounting information table 40 corresponds to one component E.

In the implementation information table 40, the "number" is a column in which the numbers assigned sequentially are registered. The "part identification code" is a column in which a part identification code (an example of part identification data) for identifying the part E is registered. "Part mounting coordinates (X coordinate, Y coordinate)" is a column in which the mounting coordinates of the component E are registered. The "part mounting angle" is a column in which the mounting angle of the component E is registered.
The description of the component identification code in the mounting information table 40 also indicates the order in which the component E is mounted, and the component E having the smallest number is mounted first.

The component detail table 41 will be described with reference to FIG. The data structure of the component detail table 41 differs depending on the type of component E. FIG. 5 shows a component detail table 41 in which detailed data of chip components are registered. One row of the component detail table 41 corresponds to one type of chip component. In the component detail table 41 of the chip component, the component identification code of the chip component and the detailed data related to the chip component are registered in association with each other. The detailed data specifically includes data representing the shape of the part (external dimensions X, Y, Z), suction height, suction time, suction speed, and the like.

Although not shown in the figure, in the case of the component detail table 41 in which the detailed data of the lead component is registered, the detailed data includes data representing the component shape (number of leads, lead length, lead width, etc.), suction height, and so on. The adsorption time, adsorption speed, etc. are registered.

The mounting information table 40 and the component detail table 41 described above are examples. The detailed data registered in the mounting information table 40 and the component detail table 41 can be appropriately determined.

(3) Component mounting data change program The component mounting data change program is a program for the operator to change the detailed data included in the component mounting data (mounting information table 40 and component detail table 41). .. The change program is executed by the control unit 24. When the change program is executed, the parts list screen 42 (see FIG. 6) and the parts details screen 43 (see FIG. 7), which will be described later, are displayed on the display unit 25A of the operation unit 25. The operator can change the detailed data on these screens.

(3-1) Parts list screen and parts details screen When the operator operates the operation unit 25 to execute the change program, the parts list screen 42 shown in FIG. 6 is first displayed. The component identification code registered in the mounting information table 40 is displayed in a list on the component list screen 42. The same component identification code may be registered in the mounting information table 40 in duplicate, but the same component identification code is not displayed in duplicate on the component list screen 42. When the operator selects one of the component identification codes on the component list screen 42 and performs a predetermined operation, the component detail screen 43 shown in FIG. 7 is displayed.

The component detail screen 43 is a screen for changing the detailed data of the component E. The component detail screen 43 shown in FIG. 7 shows a case where the component identification code (CHIP22) of the chip component is selected on the component list screen 42 shown in FIG. In the case of chip parts, detailed data representing the shape of the parts (external dimensions X, external dimensions Y, external dimensions Z, etc.) and detailed data such as suction height, suction time, and suction speed are displayed. The operator can change the value of each detailed data on the part detail screen 43 (an example of the first change process).

The detailed data changed in the past is identifiablely displayed on the component detail screen 43 (an example of the first display process). Specifically, the background of detailed data that has not been changed in the past is displayed in white. On the other hand, the detailed data changed in the past is displayed with the background colored in a color other than white. For example, in the example shown in FIG. 7, the external dimensions X (mm) and the suction height (mm) have been changed in the past, so the background is colored, and the other detailed data have not been changed in the past, so the background is white. Is displayed.

Further, on the component detail screen 43, the display form of the detailed data differs depending on the number of times the detailed data is changed. Specifically, the change program counts the number of changes for each detailed data and records it in the storage unit 28, and the more the number of changes is, the darker the background color is displayed. For example, in the example shown in FIG. 7, it is assumed that the external dimension X (mm) has been changed once and the suction height has been changed twice in the past. In this case, the suction height is displayed with a darker background than the external dimension X (mm).

As shown in FIG. 6, the background of the component identification code of the component E whose detailed data has been changed in the past is also displayed in color on the component list screen 42 (an example of the second display process). Specifically, in the example shown in FIG. 6, the detailed data of any of the parts of CHIP12 and CHIP22 has been changed in the past, and the other parts E (parts such as CHIP11, CHIP21, CHIP31) have detailed data in the past. Has not changed. In this case, CHIP 12 and CHIP 22 are colored and displayed in a color other than white, and the other component E is colored and displayed in a white background.

Also on the component list screen 42, the background is displayed in a darker color as the component identification code changes more frequently in the detailed data. For example, in the case of the above-mentioned CHIP22 component, the external dimension X (mm) is changed once and the suction height is changed twice, so that the total number of changes of the detailed data is three times. Assuming that the total number of changes in the past detailed data of the parts of CHIP 12 is 2, CHIP 22 is displayed in a darker background than CHIP 12.

(3-2) Parts list screen and parts detail screen when an error occurs In the change program, when a mounting error of part E occurs, detailed data related to the part E that can cause the mounting error is included in the change program. If it has been changed in the past, when the component detail screen 43 is displayed thereafter, the detailed data that has been changed in the past among the detailed data that may cause the mounting error is displayed in an identifiable manner.
Further, in the change program, when a mounting error of the component E occurs, if the detailed data related to the component E, which may cause the mounting error, has been changed in the past, the component list screen 42 thereafter. When displaying, the part identification code of the part E is displayed so as to be identifiable.

First, with reference to FIG. 8, an example of a mounting error caused by the component mounting data (mounting information table 40 and the component detail table 41) and detailed data that can cause the mounting error will be described. Mounting errors that occur due to component mounting data include suction error of component E, recognition error of component E, and the like.

The suction error of the component E is an error in which the mounting head 18 fails to suck the component E. The control unit 24 determines whether or not the component E is attracted to the mounting head 18 from the image obtained by capturing the component E with the component imaging camera 16, and if not, a suction error occurs. The method for determining the adsorption error is not limited to this, and can be determined by an appropriate method. The suction error occurs not only due to malfunction of components such as the mounting head 18 and the air supply device, but also due to improperly set suction height, suction time, suction speed, etc. There is also.

The recognition error of the component E is an error in which the component shape of the component E does not match the detailed data. The control unit 24 recognizes the component shape of the component E from the image of the component E captured by the component imaging camera 16, and the recognized component shape represents detailed data (external dimensions X, external dimensions Y, external dimensions Z, If it does not match the lead length, lead width, etc.), a recognition error will occur. The recognition error is caused by the fact that the shape of the component is actually distorted, and may also be caused by the malfunction of the component such as the component imaging camera 16. In addition, the recognition error may occur due to improper setting of detailed data representing the part shape.

The component detail screen 43 when an error occurs will be described with reference to FIG. For example, assume that a suction error occurs when mounting a component of CHIP22. As described above, detailed data that can cause adsorption errors are adsorption height, adsorption time, adsorption speed, and the like. In the example shown in FIG. 9, while the adsorption height has been changed in the past, the adsorption time, adsorption speed, etc. have not been changed in the past. Therefore, among the detailed data that may cause an adsorption error, the details changed in the past. The data is the adsorption height. In this case, as shown in FIG. 9, the suction height is displayed surrounded by the red frame 44 on the component detail screen 43 after the suction error has occurred. The external dimensions X (mm) have been changed in the past, but they are not surrounded by a red frame because they are not detailed data that can cause adsorption errors.

The parts list screen 42 when an error occurs will be described with reference to FIG. For example, assume that a suction error occurs when mounting a component of CHIP22. Then, it is assumed that the suction height of the CHIP22 component has been changed in the past among the detailed data that can cause a suction error. In this case, as shown in FIG. 10, CHIP 22 is displayed surrounded by a red frame 45 on the component list screen 42 after the suction error has occurred.

(4) Effect of Embodiment According to the changing device (control unit 24 and display unit 25A) according to the first embodiment, the background color of the detailed data changed in the past and the detailed data not changed on the component detail screen 43 is displayed. By differentiating, the detailed data changed in the past can be displayed in an identifiable manner. Therefore, when a mounting error of the component E occurs, the operator grasps whether or not the detailed data that may cause the mounting error in the component E has been changed in the past, and if not, the surface. By investigating the malfunction of the component E of the mounting machine 1 with priority and investigating the data for component mounting with priority when it is changed, there is a high possibility that the cause of the mounting error can be quickly investigated. Therefore, according to the changing device, there is a high possibility that the time required for recovery from the mounting error can be shortened.

According to the changing device, the darkness of the background color of the detailed data (that is, the display form of the detailed data) is changed according to the number of times the detailed data is changed on the component detail screen 43. Therefore, it becomes easy for the operator to grasp the detailed data that is frequently changed. In other words, it makes it easier for the operator to understand the detailed data that is likely to be the cause of the implementation error.

According to the changing device, in the parts list screen 42, the background color is different between the part identification code of the part E whose detailed data has been changed in the past and the part identification code of the part E whose detailed data has not been changed in the past. The part identification code of the part E whose detailed data has been changed is displayed in an identifiable manner. By doing so, when a mounting error of the component E occurs, it becomes easy for the operator to grasp whether or not the detailed data of the component E has been changed in the past. In other words, it makes it easier for the operator to know if a change in detailed data may be the cause of an implementation error.

<Embodiment 2>
The second embodiment is a modification of the first embodiment. The change program according to the second embodiment displays the history of past mounting errors of the component E and the history of changes of detailed data related to the component E when a mounting error of the component E occurs. 11 and 12) are further displayed (an example of history display processing).

Further, the change program according to the second embodiment accepts the selection of any change history from one or more change histories displayed on the history screen 46 (an example of the history selection process), and the changes selected on the history screen 46. The detailed data corresponding to the history is rolled back to the detailed data before the change in the selected change history (an example of rollback processing).

(1) History screen The history screen 46 described above includes a first history screen 46A (see FIG. 11) called from the parts list screen 42 and a second history screen 46B (see FIG. 12) called from the parts detail screen 43. ). Hereinafter, each history screen 46 will be described.

As shown in FIG. 11, when a component identification code is selected on the component list screen 42 and a predetermined operation (an operation different from the operation of displaying the component detail screen 43) is performed, the first history screen 46A is displayed. In the component list screen 42 shown in FIG. 11, CHIP 22 is surrounded by a red frame, and CHIP 22 is selected to display the first history screen 46A.

On the first history screen 46A, the occurrence history of the mounting error that occurred when the selected component E is mounted, and the change history of the detailed data related to the component E are listed. Specifically, on the first history screen 46A, the date and time when the event (error occurrence or data change) occurred is displayed in the date and time column. The event column shows whether the event that occurred is a data change or an error. Information about the event is displayed in the information column. Specifically, if the event is an error occurrence, an error code is displayed, and if the event is a data change, the name of the changed detailed data is displayed. If the event is a data change, the value before the change (0.2 in the example shown) and the value after the change (0.5 in the example shown) are displayed in the details column with an arrow symbol pointing to the right. ..

As shown in FIG. 12, when detailed data is selected on the component detail screen 43, the second history screen 46B is displayed. In the component detail screen 43 shown in FIG. 12, the suction height is surrounded by a red frame, and the case where the suction height is selected and the second history screen 46B is displayed is shown.
On the second history screen 46B, the occurrence history of the mounting error that occurred when mounting the component E (the component whose detailed data is displayed on the component detail screen 43) selected on the component list screen 42, and the component The change history of the detailed data selected on the detail screen 43 is listed. In the information column, an error code is displayed when an error occurs, and in the case of data change, the value before the change and the value after the change are displayed with an arrow symbol pointing to the right.

(2) Rollback of detailed data When any change history is selected on the first history screen 46A shown in FIG. 11, the detailed data corresponding to the change history becomes the detailed data before the change of the change history. Rolled back. For example, when the change history of the suction height is selected on the first history screen 46A shown in FIG. 11, the suction height (an example of detailed data corresponding to the selected change history) is 0 after the change of the change history. It is rolled back from .5 to 0.2, which is the detailed data before the change. The same applies to the second history screen 46B shown in FIG.

(3) Effect of Embodiment According to the changing device according to the second embodiment, the operator can easily return to the detailed data when the mounting error has not occurred, for example, by referring to the data change history. .. In addition, the operator can easily return to the detailed data before the implementation error occurs by referring to the implementation error occurrence history. Therefore, there is a high possibility that the implementation error can be recovered in a short time.

According to the change device, when the change history is selected on the first history screen 46A or the second history screen 46B, it is rolled back to the detailed data before the change in the selected change history, so that before an implementation error occurs. The work efficiency of the work of returning to the detailed data of is improved. Therefore, there is a high possibility that the time required for recovery from an implementation error can be shortened.

<Embodiment 3>
The third embodiment is a modification of the first or second embodiment. Here, a modified example of the second embodiment will be described.

The change program according to the third embodiment displays a modification candidate screen 47 (FIG. 3) that displays modification candidates for detailed data that may cause the mounting error among the detailed data related to the component E when a mounting error of the component E occurs. (See 13) is further displayed (an example of candidate display processing).
Further, the change program accepts the selection of one of the correction candidates from the one or more correction candidates displayed on the correction candidate screen 47 (an example of the candidate selection process), and provides detailed data corresponding to the selected correction candidates. Change to the selected correction candidate (an example of the second change process).

(1) Correction Candidate Screen As shown in FIG. 13, when a part identification code is selected on the part list screen 42 and a predetermined operation (an operation different from the operation of displaying the part detail screen 43) is performed, a first history is obtained. The screen 46A and the correction candidate screen 47 are displayed. In the component list screen 42 shown in FIG. 13, CHIP 22 is surrounded by a red frame, and the case where CHIP 22 is selected and the correction candidate screen 47 is displayed is shown.
In the present embodiment, when the component identification code is selected on the component list screen 42, the first history screen 46A and the correction candidate screen 47 are displayed, but the first history screen 46A may not be displayed.

The correction candidate screen 47 displays a list of correction candidates of the detailed data of the part E represented by the selected part identification code. A description of the correction candidates will be described later. On the correction candidate screen 47, information indicating the priority of the correction candidate is displayed in the priority column. The name of the detailed data is displayed in the detailed data column. In the correction candidate column, the current value of the detailed data and the correction candidate are displayed with an arrow symbol pointing to the right.

The correction candidates displayed on the correction candidate screen 47 and their priorities will be described. Correction candidates are determined based on the past change history of detailed data and the occurrence history of implementation errors. Specifically, the values corresponding to the following (A), (B), and (C) are determined as correction candidates. The priority is highest in (A) and lower in the order of (B) and (C).

(A) Value when no mounting error occurs in the corresponding component E.
For example, it is assumed that the mounting error does not occur in a certain component E before the detailed data of the component E is changed, and the mounting error occurs after the operator mistakenly changes the detailed data. In this case, among the changed detailed data, the value when the implementation error does not occur (that is, the value before the change) is determined as a correction candidate for the detailed data that can cause the implementation error.

(B) A value when a mounting error does not occur in a component E similar to the corresponding component E.
The above-mentioned (A) is based on the premise that there is data when the mounting error does not occur, but there may be no data when the mounting error does not occur. For example, immediately after the mounting work of the surface mounter 1 is started. Therefore, in (B), not the value when the mounting error does not occur in the corresponding component E, but the value when the mounting error does not occur in the similar component E is displayed as a correction candidate.

For example, it is assumed that the mounting error does not occur in a certain component E before the detailed data of the component E is changed, and the mounting error occurs after the detailed data is changed. In this case, among the changed detailed data, the value when the mounting error does not occur in the similar component E is determined as a correction candidate for the detailed data that can cause the mounting error.

Whether or not the parts E are similar is determined from the viewpoints that the types of parts (chip parts, lead parts, etc.) are the same, and the difference in outer diameter dimensions is a certain value or less. If a value that does not cause a mounting error in a similar component E, there is a possibility that a mounting error does not occur in the corresponding component E. Therefore, in the component E similar to the corresponding component E, the value when the mounting error does not occur is determined as the correction candidate.

(C) A value in the direction in which mounting errors are reduced in the corresponding component E.
For example, when a suction error of a certain part E occurs, if the suction height, which is detailed data that can cause the suction error, is changed from 0.5 mm to 0.4 mm, the suction error is reduced, but the suction error still occurs. Suppose it has occurred. In this case, since the direction in which the suction error decreases is the direction in which the suction height decreases, 0.3 mm, which is a value 0.1 mm smaller than 0.4 mm, is determined as a correction candidate.

(2) Change of detailed data When the operator selects one of the correction candidates on the correction candidate screen 47, the detailed data corresponding to the selected correction candidate is changed to the selected correction candidate. For example, assuming that the adsorption height having the highest priority (A) is selected on the correction candidate screen 47, the current value of the suction height (an example of detailed data corresponding to the selected correction candidate) is 0.4 mm. Is changed to 0.2 mm (restore).

(3) Effect of the Embodiment According to the change device according to the third embodiment, when a mounting error of the component E occurs, correction candidates of detailed data that may cause the mounting error are displayed. Therefore, the operator can easily change the detailed data so that the implementation error does not occur. Therefore, the work efficiency of the work is improved, and there is a high possibility that the time required for recovery from the mounting error can be shortened.

According to the change device, correction candidates are displayed based on the past change history of detailed data, so that correction candidates that are unlikely to cause an implementation error can be displayed.

<Other embodiments>
The technology disclosed herein is not limited to the embodiments described above and in the drawings, and for example, the following embodiments are also included in the technical scope disclosed herein.

(1) In the above embodiment, a case where all the times when the detailed data is changed is counted will be described as an example. However, it is not always necessary to count all changes. For example, the count of the number of changes in the detailed data may be started when a predetermined condition is satisfied. Specifically, for example, the number of changes in detailed data may not be counted until the tuning of the mounting operation is completed. By doing so, it is possible to reduce the possibility that it becomes difficult to identify the detailed data that is the cause of the implementation error.

The above-mentioned "until tuning is completed" is an example of a predetermined condition. The predetermined conditions are not limited to this. For example, the predetermined condition may be "until a certain period of time elapses after the component mounting data is first changed" or "until the production of a predetermined number of printed circuit boards P is completed". It may be "until the operator instructs the start of counting".

(2) In the above embodiment, on the part detail screen 43, the detailed data changed in the past can be displayed in an identifiable manner by making the background color different between the detailed data changed in the past and the detailed data not changed in the past. The case of doing this was explained as an example. However, the method of displaying the detailed data changed in the past in an identifiable manner is not limited to this. For example, the color of the characters displaying the detailed data changed in the past may be displayed identifiable by being different from the color of the characters displaying the detailed data not changed in the past. Alternatively, the detailed data changed in the past may be displayed by enclosing it in a frame, may be blinked, or the color depth may be different. Moreover, you may combine these display methods.

(3) In the above embodiment, as an example in which the display form is changed according to the number of times the data is changed, a case where the background density is changed according to the number of changes has been described as an example. However, the method of changing the display form according to the number of times the data is changed is not limited to this. For example, the number of data changes may be displayed numerically.

(4) In the above embodiment, the case where all the part identification codes (part identification code whose detailed data has been changed and part identification code whose detailed data has not been changed) are displayed on the part list screen 42 has been described as an example. On the other hand, only the part identification code whose detailed data has been changed (in other words, the part identification code whose background is colored) may be displayed. Alternatively, the operator may be able to select whether to display all the part identification codes or only the part identification codes whose detailed data has been changed. The same applies to the component detail screen 43.

(5) In the above embodiment, the case where the control unit 24 and the display unit 25A included in the surface mounter 1 operate as the changing device has been described as an example, but the changing device is not limited to this. For example, the changing device may be a personal computer.

(6) In the above embodiment, a case where each screen such as the component list screen 42 is displayed on the display unit 25A included in the surface mounter 1 has been described as an example. On the other hand, a screen printing machine, a dispenser, a surface mounting machine 1, a reflow device, and the like may be displayed on a display unit provided on a component mounting line connected in series.

(7) Although the above-described third embodiment has been described as a modified example of the second embodiment, the third embodiment may be a modified example of the first embodiment. In that case, the history screen 46 described in the second embodiment is not displayed.

(8) In the above embodiment, the printed circuit board P has been described as an example of the work, but the work is not limited to the printed circuit board P. For example, when the surface mounter 1 mounts the component E on a work having a three-dimensional shape, the work may be an arbitrary mounting target having a three-dimensional shape.
