Description

The technology disclosed in this specification relates to a component mounting data changing device, a changing program, and a surface mounter.

2. Description of the Related Art Conventionally, there has been known a surface mounter in which a mounting head holds a component supplied via a component supply tape, a component tray, or the like, and mounts the component on a work such as a printed circuit board. As a mounting head, for example, one that sucks a component by negative pressure, one that clamps a component by chucking, and the like are known.

In general, a surface mounter operates based on component mounting data. The component mounting data is sometimes called a mounting program. For example, if the mounting head picks up components using negative pressure, the data for component mounting includes the component identification code of the component to be mounted on the workpiece, the mounting order, the mounting coordinates, the mounting angle, the data representing the component shape, and the suction height. , adsorption time, and adsorption speed.

The content of the data representing the shape of the part differs depending on the type of the part. For example, in the case of a lead component having leads (SOP: Small Outline Package, QFP: Quad Flat Package, etc.), data representing the component shape includes the number of leads, lead length, lead width, and the like. In the case of a rectangular parallelepiped or cubic chip component (resistor, etc.), data representing the component shape includes data such as the length, width, and height of the component. The pickup height is the vertical position of the mounting head when the component is picked up 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 pickup speed is the lowering speed of the mounting head when picking up the component.

Data for component mounting is created by an optimization program. The optimization program is a program for optimizing the mounting order of components so as to minimize the mounting time when mounting a plurality of components on one workpiece. In general, the surface mounter operator can change the data included in the component mounting data created by the optimization program.

However, changing the data may cause implementation errors due to the changes. For example, in general, a surface mounter uses a camera to photograph a component picked up by a mounting head, recognizes the shape of the component, and compares it with data representing the shape of the component to determine whether the shape of the component is good or bad. Therefore, when the data representing the shape of the component is changed, the changed data may be inappropriate, which may increase the frequency of determining that the shape of the component is defective. Alternatively, if the picking height or picking time is changed, the changed picking height or picking time is inappropriate, which may make it difficult to pick up the component and increase the frequency of picking errors.

For this reason, conventionally, when a mounting error occurs in the surface mounter after the component mounting data is changed, it is known to return the component mounting data 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 apparatus after the component mounting data is changed satisfies a predetermined condition (suction rate, etc.). It describes that the data for component mounting is automatically restored to the data before the change.

Japanese Patent No. 6248286

The cause of the mounting error is not necessarily the change of the component mounting data, but may be caused by malfunction of the components constituting the surface mounter. For example, in the case of a suction error, the suction error may occur due to malfunction of component parts such as the mounting head and 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 data for mounting the component is returned to the state before the change.

For this reason, the operator needs to distinguish between the cause of the mounting error being the modification of the component mounting data and the defective operation of the components constituting the surface mounter. However, since this separation takes time, it has been difficult to recover from mounting errors in a short period of time.

This specification discloses a technique that increases the possibility of shortening the time required for recovery from mounting errors.

(1) A changing device disclosed in this specification is a component mounting data changing device containing a plurality of data for controlling the operation of a surface mounter that mounts components on a workpiece, and a processing unit, wherein the processing unit performs a first change process for accepting changes to the data, and displays the data changed by the first change process in the past in an identifiable manner on the display unit. and a first display process to be performed.

When an implementation error occurs, if the data that could cause the implementation error has been changed in the past, it is suspected that the implementation error occurred due to the inappropriate change of the data. Conversely, if the data that could cause the mounting error has not been changed in the past, malfunction of the components of the surface mounter is suspected.

According to the above-described change device, when a mounting error occurs, it becomes easier for the operator to grasp whether or not the data that could cause the mounting error has been changed in the past. For this reason, when a mounting error occurs, the operator can grasp whether or not the data that can cause the mounting error has been changed in the past, and if it has not been changed, prioritize the malfunction of the component. Investigating and, if changed, preferentially investigating the component mounting data increases the possibility of quickly identifying the cause of the mounting error. Therefore, according to the above-described changing device, it is highly likely that the time required for recovery from mounting errors 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.

Data that has been changed more frequently is more likely to be the cause of an implementation error. Because the number of changes is large, there is a possibility that implementation errors occurred many times in the past due to the data, and the operator changed the data to resolve the implementation errors each time an implementation error occurred. It is from.
According to the above change device, it becomes easier for the operator to grasp the data that is changed many times. In other words, it becomes easier for the operator to grasp the data that is likely to be the cause of the mounting error.

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

In other words, it becomes easier for the operator to grasp whether or not there is a possibility that the change in the detailed data is the cause of the mounting error.

(4) In the second display processing, the processing unit may change the display form of the component identification data according to the number of times the detailed data has been changed.

According to the above change device, it becomes easier for the operator to grasp the parts whose detailed data have been changed many times. In other words, it becomes easier for the operator to grasp whether or not there is a high possibility that the change in detailed data is the cause of the mounting error.

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

When mounting a new part, the data may change frequently due to tuning of the mounting operation. If the change in that case is also included in the number of changes, when an implementation error actually occurs, it becomes difficult for the operator to identify the data causing the implementation error.
According to the above change device, for example, the number of data changes is not counted until tuning is completed, and counting is started when the condition that tuning is completed (an example of a predetermined condition) is met. It is possible to reduce the possibility that it becomes difficult for the operator to identify the data that causes the error.

(6) when the processing unit executes the first display process after a mounting error of the component has occurred and the data that could cause the mounting error has been changed in the past; , the data that has been changed in the past among the data that may cause the mounting error may be displayed in an identifiable manner.

According to the above-described change device, it becomes easier for the operator to grasp the data that may have caused the mounting error, so there is a high possibility that the time required to recover from the mounting error can be shortened.

(7) When a mounting error of the component occurs, if the detailed data that may cause the mounting error among the detailed data regarding the component has been changed in the past, the processing unit performs the following: When executing the second display process, the component identification data of the component may be displayed in an identifiable manner.

According to the above change device, when a component mounting error occurs, the operator can easily grasp whether or not the change in the detailed data related to the component may be the cause of the mounting error. It is more likely that the time required to recover from implementation errors can be shortened.

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

According to the above change device, the operator can easily return the data to the state 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 occurrence of the mounting error by referring to the occurrence history of the mounting error. This increases the possibility of recovering from mounting errors in a short time.

(9) In the history display process, the processing unit displays at least the change history of the detailed data, and selects one of the one or more change histories displayed in the history display process. history selection processing for receiving; and rollback processing for rolling back the detailed data corresponding to the change history selected in the history selection processing to data before change in the selected change history. may

According to the above change device, the working efficiency of the work of restoring the data before the mounting error occurred is improved. Therefore, the possibility of shortening the time required to recover from the mounting error increases.

(10) When a component mounting error occurs, the processing unit performs candidate display processing for displaying correction candidates for the data that may cause the mounting error on the display unit, and displaying by the candidate display processing. a candidate selection process for receiving a selection of one of the correction candidates from among the one or more of the correction candidates selected; and a second change process of changing to a candidate.

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

The change history contains at least the data before the change. More preferably, the change history includes data after change and date and time of change.
According to the above change device, it is possible to display correction candidates that are highly unlikely to cause mounting errors, based on the past change history of data.

Here, one mounting information table 40 (see FIG. 4) is provided for each type of component E (chip component, lead component, etc.). A case will be described as an example in which the table is composed of one or more component detail tables 41 (see FIG. 5).

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

In the mounting information table 40, "number" is a column in which sequentially assigned numbers are registered. "Component identification code" is a field in which a component identification code for identifying component E (an example of component identification data) is registered. "Mounting coordinates of component (X coordinate, Y coordinate)" is a field in which mounting coordinates of component E are registered. "Mounting angle of component" is a column in which the mounting angle of 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 smaller number is mounted first.

The component details table 41 will be described with reference to FIG. The data structure of the part detail table 41 differs depending on the type of part E. FIG. 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 regarding the chip component are associated and registered. The detailed data specifically includes data representing the component shape (external dimensions X, Y, Z), suction height, suction time, suction speed, and the like.

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

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

(3-1) Parts List Screen and Parts Detail Screen When the operator operates the operation unit 25 to execute the change program, the parts list screen 42 shown in FIG. 6 is displayed first. A list of component identification codes registered in the mounting information table 40 is displayed on the component list screen 42 . Although the same component identification code may be registered redundantly in the mounting information table 40 , the same component identification code is not displayed redundantly 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, a component detail screen 43 shown in FIG. 7 is displayed.

The part detail screen 43 is a screen for changing the detailed data of the part E. FIG. A 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 a chip component, detailed data representing the shape of the component (outer dimension X, outer dimension Y, outer dimension Z, etc.), suction height, suction time, suction speed, and other detailed data are displayed. The operator can change the value of each detailed data on the parts details screen 43 (an example of the first change process).

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

Further, on the component details screen 43, the display form of the detailed data differs according to the number of times the detailed data has been 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 detailed data is changed, 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 in the past and the suction height has been changed twice. In this case, the suction height is displayed with a darker background than the external dimension X (mm).

As shown in FIG. 6, also on the parts list screen 42, the background of the part identification code of the part E whose detailed data has been changed in the past is displayed in color (an example of the second display process). Specifically, in the example shown in FIG. 6, one of the detailed data of the parts CHIP12 and CHIP22 has been changed in the past, and the detailed data of the other parts E (parts such as CHIP11, CHIP21, and CHIP31) has been changed in the past. is unchanged. In this case, the backgrounds of CHIP12 and CHIP22 are displayed in colors other than white, and the other parts E are displayed in colors with a background of white.

In the parts list screen 42 as well, a part identification code whose detailed data has been changed more frequently is displayed with a darker background. For example, in the case of the CHIP 22 component described above, the external dimension X (mm) is changed once and the suction height is changed twice, so the total number of changes in the detailed data is three. Assuming that the total number of past detailed data changes for CHIP12 is two, CHIP22 is displayed with a darker background than CHIP12.

(3-2) Parts List Screen and Parts Detail Screen When an Error Occurs If it has been changed in the past, when the component details screen 43 is displayed after that, the detailed data changed in the past among the detailed data that may cause the mounting error is displayed in an identifiable manner.
Furthermore, when a mounting error of component E occurs, the change program displays the component list screen 42 after that, if the detailed data that could cause the mounting error among the detailed data regarding the component E has been changed in the past. is displayed, the component identification code of the component E is displayed so as to be identifiable.

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

The pickup error of the component E is an error that the mounting head 18 fails to pick up the component E. FIG. The control unit 24 determines whether or not the component E is picked up by the mounting head 18 from the image of the component E picked up by the component imaging camera 16, and if not picked up, it is regarded as a pickup error. The method for judging the adsorption error is not limited to this, and it can be judged by an appropriate method. Suction errors are caused not only by operational failures of component parts such as the mounting head 18 and the air supply device, but also by improper settings of the suction height, suction time, suction speed, and the like. There is also

A recognition error of the part E is an error that the part shape of the part 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 is converted into detailed data representing the component shape (external dimension X, external dimension Y, external dimension Z, lead length, lead width, etc.), it is regarded as a recognition error. Recognition errors are caused not only by actual distortion of the shape of the component, but also by operational failures of components such as the component imaging camera 16 . Recognition errors may also occur due to inappropriate setting of detailed data representing the part shape.

The component details screen 43 when an error occurs will be described with reference to FIG. For example, assume that a pickup error occurs when mounting a component of CHIP 22 . As described above, the detailed data that can cause adsorption errors are the adsorption height, adsorption time, adsorption speed, and the like. In the example shown in FIG. 9, while the suction height has been changed in the past, the suction time and suction speed have not been changed in the past. The data are adsorption heights. In this case, as shown in FIG. 9, the pickup height is displayed surrounded by a red frame 44 on the component detail screen 43 after the pickup error occurs. Although the outside dimension X (mm) was changed in the past, it is not detailed data that could cause an adsorption error, so it is not surrounded by a red frame.

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

(4) Effect of Embodiment According to the changing device (the control unit 24 and the display unit 25A) according to the first embodiment, the detailed data that has been changed in the past and the detailed data that has not changed in the component details screen 43 are colored in the background color. , the detailed data changed in the past are identifiably displayed. Therefore, when a mounting error occurs in the component E, the operator can grasp whether or not the detailed data that could cause the mounting error in the component E has been changed in the past. By preferentially investigating the malfunction of the component E of the mounting machine 1 and preferentially investigating the data for component mounting when it is changed, the possibility of quickly investigating the cause of the mounting error is increased. Therefore, according to the changing device, there is a high possibility that the time required to recover from the mounting error can be shortened.

According to the changing device, the density 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 . For this reason, it becomes easier for the operator to grasp the detailed data that is frequently changed. In other words, it becomes easier for the operator to grasp the detailed data that is likely to be the cause of the mounting error.

According to the changing device, on the parts list screen 42, 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 have different background colors. , the part identification code of the part E whose detailed data has been changed is identifiably displayed. This makes it easier for the operator to know whether or not the detailed data of the component E has been changed in the past when a mounting error of the component E occurs. In other words, it becomes easier for the operator to grasp whether or not there is a possibility that the change in the detailed data is the cause of the mounting error.

According to the changing device, the density of the background color (that is, the display form of the detailed data) is changed on the parts list screen 42 according to the number of times the detailed data is changed. Therefore, it becomes easier for the operator to grasp the part E that has been changed many times. In other words, it becomes easier for the operator to grasp whether or not there is a high possibility that the change in detailed data is the cause of the mounting error.

According to the change device, when a mounting error of the component E occurs, if the detailed data that could cause the mounting error among the detailed data related to the component E has been changed in the past, the component details screen 43 is displayed after that. When displaying, among the detailed data that may cause the implementation error, the detailed data that has been changed in the past is surrounded by a red frame (that is, displayed in an identifiable manner). This makes it easier for the operator to grasp the detailed data that may have caused the mounting error, thus increasing the possibility of shortening the time required to recover from the mounting error.

According to the change device, when a mounting error of the component E occurs, if the detailed data that could cause the mounting error has been changed in the past, when the component list screen 42 is displayed after that, the component E Enclose the part identification code in a red frame (that is, display it in an identifiable manner). In this way, when a mounting error occurs in the component E, it becomes easier for the operator to grasp whether or not the change in the detailed data of the component E may be the cause. It is highly possible that the time required for recovery can be shortened.

<Embodiment 2>
The second embodiment is a modification of the first embodiment. The change program according to the second embodiment displays a history screen 46 ( 11 and 12) is further displayed (an example of history display processing).

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

(1) History Screen The history screen 46 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 details screen 43. ). Each history screen 46 will be described below.

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

On the first history screen 46A, the history of mounting errors occurring when the selected component E is mounted and the change history of detailed data regarding the component E are listed. Specifically, the date and time when an event (error occurrence or data change) occurred is displayed in the date and time column on the first history screen 46A. The event column displays whether the event that occurred is data change or error occurrence. Information about the event is displayed in the information column. Specifically, if the event is error occurrence, an error code is displayed, and if the event is 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 detail column with a right-pointing arrow symbol between them. .

As shown in FIG. 12, when detailed data is selected on the component details screen 43, a 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, indicating that the suction height is selected and the second history screen 46B is displayed.
The second history screen 46B displays the history of mounting errors that occurred when mounting the component E selected on the component list screen 42 (the component whose detailed data is displayed on the component detail screen 43), and the history of component errors. A change history of the detailed data selected on the detailed screen 43 is listed. In the information column, an error code is displayed when an error occurs, and when data is changed, a value before change and a value after change are displayed with a right-pointing arrow symbol interposed therebetween.

(2) Rollback of detailed data When any of the change histories is selected on the first history screen 46A shown in FIG. 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 changed to 0 .5 is rolled back 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 change device according to the second embodiment, the operator can easily return to the detailed data when no implementation error occurred by referring to the data change history, for example. . Also, by referring to the history of occurrence of mounting errors, the operator can easily return to the detailed data before the occurrence of the mounting error. This increases the possibility of recovering from mounting errors in a short time.

According to the change device, when a change history is selected on the first history screen 46A or the second history screen 46B, the detailed data before change in the selected change history is rolled back. The work efficiency of returning to detailed data is improved. Therefore, the possibility of shortening the time required to recover from the mounting error increases.

<Embodiment 3>
Embodiment 3 is a modification of Embodiment 1 or 2. FIG. Here, a modification of the second embodiment will be described.

The change program according to the third embodiment displays a correction candidate screen 47 (Fig. 13) is further displayed (an example of candidate display processing).
Further, the change program accepts selection of one of the one or more correction candidates displayed on the correction candidate screen 47 (an example of candidate selection processing), and sends detailed data corresponding to the selected correction candidate to Change to the selected correction candidate (an example of second change processing).

(1) Correction Candidate Screen As shown in FIG. 13, when a part identification code is selected on the parts list screen 42 and a predetermined operation (an operation different from the operation for displaying the parts details screen 43) is performed, the first history A screen 46A and a correction candidate screen 47 are displayed. In the parts list screen 42 shown in FIG. 13, CHIP22 is surrounded by a red frame, indicating a case where CHIP22 is selected and the correction candidate screen 47 is displayed.
In this embodiment, when a 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 for the detailed data of the part E represented by the selected part identification code. A description of the correction candidates will be given later. In the correction candidate screen 47, information indicating the priority of the correction candidates is displayed in the priority column. The detailed data column displays the name of the detailed data. In the correction candidate column, the current value of the detailed data and a correction candidate are displayed with a rightward arrow symbol interposed therebetween.

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

(A) Value when no mounting error occurs in the corresponding component E.
For example, it is assumed that a mounting error did not occur before the detailed data of a part E was changed, and a mounting error occurred after the detailed data was changed by an operator. In this case, for the detailed data that may cause the mounting error among the changed detailed data, the value when the mounting error does not occur (that is, the value before the change) is determined as a correction candidate.

(B) A value when no mounting error occurs in a component E similar to the corresponding component E.
Although (A) described above is based on the assumption that there is data when no mounting error has occurred, there may be cases where there is no data when no mounting error has occurred. For example, immediately after the mounting operation of the surface mounter 1 is started. Therefore, in (B), instead of the value when no mounting error occurs in the corresponding component E, the value when no mounting error occurs in the similar component E is displayed as a correction candidate.

For example, assume that a mounting error did not occur before the detailed data of a certain component E was changed, but a mounting error occurred after the detailed data was changed. In this case, among the changed detailed data, for the detailed data that can cause the mounting error, the value obtained when the similar component E did not cause the mounting error is determined as a correction candidate.

Whether or not it is a similar component E is judged from the viewpoints of the same component type (chip component, lead component, etc.), the difference in outer diameter size being equal to or less than a certain value, and the like. A value in which a mounting error does not occur in a similar component E may cause a mounting error in the corresponding component E as well. For this reason, the value when no mounting error occurs in the component E similar to the relevant component E is determined as a correction candidate.

(C) A value in the direction in which the mounting error is reduced in the corresponding component E.
For example, when a pickup error occurs in a part E, if the pickup height, which is the detailed data that can cause the pickup error, is changed from 0.5 mm to 0.4 mm, the pickup error is reduced, but the pickup error still occurs. Suppose it happened. 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 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, if the suction height with the first 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 (undone) to 0.2 mm.

(3) Effect of the Embodiment According to the changing device according to the third embodiment, when a mounting error of the part E occurs, correction candidates for detailed data that may cause the mounting error are displayed. For this reason, the operator can easily change the detailed data so that mounting errors do not occur. Therefore, the work efficiency of the work is improved, and the possibility of shortening the time required for recovery from the mounting error is increased.

According to the change device, since correction candidates are displayed based on the past change history of detailed data, it is possible to display correction candidates that are highly unlikely to cause mounting errors.

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

(1) In the above embodiment, the case where all the number of times detailed data is changed has been described as an example. However, not all changes need to be counted. For example, counting of the number of changes in 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 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 mounting error.

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

(2) In the above embodiment, detailed data changed in the past are displayed in a distinguishable manner by using different background colors for detailed data changed in the past and detailed data not changed in the component details screen 43. The case of doing is explained as an example. However, the method of identifiably displaying detailed data changed in the past is not limited to this. For example, the color of characters displaying detailed data that has been changed in the past may be made different from the color of characters displaying detailed data that has not been changed in the past so that it can be displayed in an identifiable manner. Alternatively, detailed data that has been changed in the past may be displayed by enclosing it in a frame, blinking, or different shades of color. Also, these display methods may be combined.

(3) In the above embodiment, as an example of changing the display mode according to the number of data changes, the 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 mode according to the number of data changes 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 (the part identification codes whose detailed data have been changed and the part identification codes whose detailed data have 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 select whether to display all the component identification codes or display only the component identification codes whose detailed data have 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 a changing device has been described as an example, but the changing device is not limited to this. For example, the modification device may be a personal computer.

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

(7) Although the third embodiment has been described as a modification of the second embodiment, the third embodiment may be a modification 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 is used as an example of the workpiece, but the workpiece is not limited to the printed circuit board P. For example, when the surface mounter 1 mounts a component E on a three-dimensional work, the work may be any mounting target having a three-dimensional shape.
