Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component data processing method for creating, classifying, and managing data of a component library of electronic components, and a recording medium on which is recorded a program.

[0002]

2. Description of the Related Art Conventionally, there is a board unit manufacturing line for manufacturing a board unit having a large number of electronic components mounted on a board. In general, this board unit production line
A substrate supply device for supplying a substrate, a dispenser for attaching or applying paste-like solder or the like to a predetermined position on the supplied substrate, and mounting (mounting) chip-like electronic components on the substrate to which the solder or the like is attached or applied. A) a component mounting device, a reflow furnace for fixing the mounted electronic components on a substrate, and a substrate storage device for storing a completed substrate unit in which the mounted electronic components are fixed.

Each device has a guide rail and a conveyor belt in its own device, processes a substrate carried in from a device in a preceding process, and carries it out to a device in a subsequent process. Above all, the component mounting device operates as a device for mounting electronic components on a circuit board by an NC program, and includes a large number of chip-shaped electronic components such as ICs, resistors, capacitors, etc. on a substrate which is automatically carried into the device itself. Is automatically mounted by the work head.

In recent years, as a component mounting apparatus, not only a so-called chip mounter for mounting only chip-shaped electronic components, but also a general-purpose deformed component mounting machine for mounting various deformed components has been put into practical use. The mounting device includes them. In order to automatically mount electronic components on a circuit board in this way, the shape and position of the electronic components taken out of the component supply device by the work head (the state and posture held by the work head) are determined by a special light irradiation device or the like. After recognizing with the component recognition camera, specifying the shape and position of the electronic component, determining whether the product is good or defective based on the shape recognition, confirming that the product is good, The position is corrected based on the position recognition so that the electronic component can be mounted at a correct position on the circuit board in a correct state, and the electronic component is mounted on the circuit board at the corrected position.

In an NC program for causing a component mounting apparatus to perform such processing, a large number of data indicating the type, name, size, shape, and position and orientation of a board to be mounted are described as parameters. Have been. And
An operator creates such an NC program,
When editing or modifying, the operator must correctly recognize the attributes such as the types, names, dimensions, and shapes of the electronic components as described above, but since the types of components are extremely diverse, I can't remember each one. In such a case, the parts classification table is referred to.

In order to create a component classification table as a data file for classifying and managing such various types of electronic components, it is often the case that components are sorted by product type or by shape. When sorting by shape, those having the same or similar shape are classified, and parts that are largely sorted in such shape are further added with data such as predetermined dimensions and shapes specific to the part. In general, a method of individually specifying the information is used. And such a kind classification and a shape classification are managed and operated as a classification group.

The data group of the minimum unit in the data file described as the component classification table, that is, the component of the data of one component is handled as a component library. The parts library is classified and classified according to a certain division frame, that is, a sorting standard. Conventionally, as a component of a parts library to be subjected to this sorting criterion, for example, in a parts library whose group name belongs to the classification of QSP, a body is a square, and leads (electrode terminals) are attached to all four sides. That the arrangement direction is outward, that the number of arrangements is the same in all four directions, that there are 200 in total (that is, that there are 50 on each side)
Are the criteria for the definition.

Further, within the group, the width of the entire shape,
A lower hierarchical group specialized by length or the like may be formed. For example, in the QFP classification group, the lower hierarchical group is divided into a rectangular group and a square group. Generally, a large number of component libraries corresponding to specific types of components are prepared, but this management method differs depending on the user. For example, in order for the component recognition camera to recognize this component, the operator selects which component library data should be used.

Conventionally, such a component classification table is generally created by a manufacturer of a component mounting apparatus for mounting electronic components on a circuit board, and is classified from the above-mentioned upper hierarchy to a lower hierarchy. Standards have also been determined by manufacturers. The parts classification table created by the manufacturer is used by a user (a factory that installs a component mounting apparatus and produces a board unit).

[0010]

By the way, with recent technological advances and diversification of electronic components (hereinafter simply referred to as components), when they are classified, they do not apply to the type classification or are confused in selecting the type classification. There is an increasing number of so-called deformed parts having shapes different from normal shapes that do not fit in the shape classification or are unclear about the selection of the shape classification, that is, do not fit in the conventional classification. Looking at trends in the parts industry, it is expected that the trend will continue.

For this reason, if the manufacturer of the component mounting apparatus prepares only the types of fixed components, it cannot keep up with the increase in the number of classification groups in the component classification table, or the component classification table cannot be created. There are situations that are difficult. In such a case, deformed parts that cannot be classified into the existing classification are classified into a temporary group, for example, “other group”. However, the components classified into such a temporary group are different from each other and cause confusion in the component management system on the user side.

In the past, the component classification table provided by the component mounting equipment maker did not always match the management and operation system of the user. There is no other way to make the component mounting apparatus recognize the component when operating it, except by using a component classification table created by the component mounting apparatus manufacturer.

For this reason, if there is a production order for a board unit using a completely new kind of component, the user will be in trouble in processing. In such a case, contact the manufacturer,
It has been repeated that a manufacturer adds classification data of a parts classification table. As described above, the parts classification table is unsatisfactory because the user has no degree of freedom.

[0021]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram schematically illustrating a configuration of a processing device used in a component data processing method for creating a component library of electronic components (hereinafter, simply referred to as components) according to an embodiment. As shown in FIG. 1, the processing device 1 includes a display 2 and a computer main body 3.
The computer body 3 includes a CPU,
RAM and RO storing predetermined programs and data
A storage device 4 such as an M or HD (hard disk) is built in. Further, the computer main body 3 is provided with a recording medium reading section 5, which is a portable recording medium such as a CD-ROM or a floppy (registered trademark) inserted from the outside. A program or data is read from the medium 6, and the read program or data is stored in the RAM or the HD.

Although not shown, the computer main body 3 is provided with a transmission control unit. The transmission control unit is connected to a network (not shown) via the transmission control unit. A desired program 8 can be downloaded from the user 7.

The processing apparatus 1 implements the following component data processing method based on the application program of the present invention read from the recording medium 6 or the program supplier 7 as described above. FIGS. 2A and 2B are diagrams showing an example of the definition of components of a component library when a component library is created and classified in the component data processing method executed in the processing device 1. is there.

The part 11 shown in FIG. 1A is a deformed part having a triangular shape different from a normal square part, that is, a part having a regular shape but a deformed part. This part 11
The component elements of the part library when creating the part library are triangle body part 11a and this body part 11a.
This is defined by four parts: a lead row 11b projected downward from a, a lead row 11c projected upward and left, and a lead row 11d projected upward and right. That is, the part 11 is represented by a combination of four characteristic parts.

It is to be noted that these parts 11a to 11d are each part of the part 11 and are considered to constitute features of the part. Also, the part 12 shown in FIG.
Are irregular shaped parts, ie irregular shaped irregular parts. In the case of the part 12, a component of the part as a part library is defined by a circle 12a on the upper left, a straight line 12b on the lower left, and a straight line 12c on the right. In other words, the part 12 is represented by three features of a circle and two straight lines.

As described above, the shape, arrangement, or arrangement of each part such as a square, a circle, a line, a triangle, a corner, and a lead is defined as one or a combination of two or more as a component of a parts library. In other words, the components of the component library are defined regardless of the format of the component library prepared in advance by the component mounting apparatus manufacturer.

The purpose of creating a parts library is to recognize a part with a part recognition camera, that is, to specify the position of the part, that is, the state (posture) held by the work head. There is no need to have it as data. A part is represented by a characteristic part in all shapes including a shape that can be vectorized along the outer shape.

The component library of the present embodiment can define constituent elements regardless of the conventional classification method created by the component mounting apparatus manufacturer. Of course, it is often more convenient to classify the same kind of parts collectively, so in that case, a classification group is created.

FIG. 3 shows a case where a classification group is created.
FIG. 9 is a diagram illustrating an example of a standard for defining a component of a parts library. In the example of the component library classification standard table 15 shown in FIG. 10, as shown in the “classification name” column in the leftmost column, “QF
P group 16, chip group 17, SO
P "group 18," BGA "group 19," PLC
C ”group 20 and“ SOJ ”group 21 6
Types of groups are set.

The definition of the constituent elements in each of these groups is as shown in the "Definition Rule" column in the center column.
When the classification name is QFP group 16, the definition rule is that a square body and four lead rows, upward, downward, leftward, and rightward, are arranged outward from the body. Is a square body, the classification name is SOP group 18, and the definition rule is that a square body and two upward and downward lead rows are arranged outward from the body, and the classification name is BGA group. 19, the definition rule is that an array of square bodies and circular groups is arranged in the body.

Further, in the case where the classification name is PLCC group 20, the definition rule is that a square body and four rows of upward, downward, leftward and rightward strings are arranged toward the inside of the body, and Is SOJ Group 2
In 1, the definition rule is that a square body and two upward and downward lead rows are arranged toward the inside of the body. And "Definition shape" in the rightmost column
In the column, the shape corresponding to the above-described definition rule of each classification group is represented as an image.

FIG. 2 shows a standard classification standard, which is almost the same as a standard previously prepared by a component mounting apparatus maker in advance. This classification standard is easy to understand because it has the information of the parts library as it is,
Therefore, the setting contents are clear at the time of newly creating this classification group, and therefore, even when a new classification group is provided, it can be created from the parts library, so that there is an advantage that the creation of the classification proceeds smoothly.

In the past, the above-described classification was based only on the classification standards prepared in advance by the component mounting apparatus maker. However, in the present embodiment, the above-described standard classification standards are also described below. Thus, the user can arbitrarily change the criteria and re-classify. FIG. 4 is a diagram showing a part library group of the present example in which the deformed parts shown in FIGS. 2A and 2B are added to the above-described standard classification criteria. 6 from “QFP” group 16 to SOJ group 21 shown in FIG.
Among the types of classification groups, the “QFP” group 16 is classified according to the difference in the number of leads, and the BGA group 19
In the classification according to the difference in the arrangement method of the round shape, 3
One lower tier classification and two lower tier classifications have been created.

The creation of a lower-level classification based on the difference in the number of read lines is similar to that of the SOP group 18 and the PLCC group 2.
0 and SOJ group 21 are also possible. Similarly, for the component 11 which is an independent component library, a lower-level classification group can be created based on the difference in the number of leads. Of course, it is easy for other groups to create a lower level classification based on a difference in body dimensions instead of the number of leads.

Further, according to the concept of the components of this embodiment,
The “QFP” group 16 and the “SOP” group 1
It is possible to classify the component libraries of the two component groups 8 and the component library of the component 11 into one group. In addition, the “QFP” group 16
It is also possible to classify the part library of the part 11 and the part library of the part 11 into one group.

Further, the combination of the components of "one circular shape at a special position, a lower straight line, and a horizontal straight line" allows the BGA
The component library of the group 19 and the component library of the component 12 can be collectively classified into one group. As described above, the component library of the present example is simply created as a component library having a component part or a plurality of combinations of the parts or their initial setting values as components. They can be used by grouping them into classification groups.

FIGS. 5A and 5B are diagrams schematically showing an example of a dependency relationship between a classification group and a part library used by freely grouping into such a desired classification group. As shown in FIGS. 7A and 7B, the part library 1 of the classification group 1 shown in FIG. 7A has been changed in grouping, and the parts library 1 is classified as shown by a broken-line arrow a in FIG. Group 2
Have moved to. Classification group 1 also shown in FIG.
The grouping of parts library 2 has also been changed.
As shown by the broken line arrow b in FIG. Also, the parts library 3 of the classification group 2 shown in FIG.
The classification has been changed to classification group 1 as shown by.

In this manner, the component library is sorted into the classification groups as a requirement for grouping arbitrary components as far as the operator can come up with, and the desired component is easily matched with the desired component from the classification group of the desired component. To find the parts library to be used.

FIG. 6A is a flowchart showing a process of creating a component library as described above by an operator using the processing apparatus 1 of FIG. 1, and FIG. 6B is a diagram showing an increase in the number of similar component libraries. 9 is a flowchart of a process for grouping the component libraries into groups according to the above. FIG.
3B, the left column shows the processing operation of the processing apparatus 1 and the right column shows the processing operation of the operator.

As shown in FIG. 1A, the operator first specifies one or more parts (features) that match the part shape for creating a part library. This part is the processing device 1
Is selected and specified from among those registered in advance. When a plurality of parts are to be designated, their relative positional relationship is designated so as to match the part shape (step O1).

Based on the designation, the processing device 1 registers information on the designated part and the positional relationship in a predetermined storage area of the storage device 4 as a component library (step S1).
). The operator repeats the same for the number n of parts (... Step On), and based on this, the processing apparatus 1 repeats the same processing as described above for the number n of parts (.)
.. Step Sn).

As the parts library is created in this way, the number of similar parts libraries increases.
It is easier to manage by appropriately classifying. Therefore, a classification group is created. As shown in FIG. 2B, the operator selects and designates one component library representing the classification from the similar component libraries for creating the classification group. Then, for example, "classification A" is designated as the classification group name (step OP1).

With this designation, the processing device 1 registers the information of the designated component library as a classification group. The classification group name is registered as “class A”. When the classification group is illustrated, all the registered parts of the parts library are displayed. The classification group has not only a function of a container for classification, but also a function of newly creating a model of a part library belonging to the classification. This template is created and registered in its classification. That is, the classification group has a part and its position information as a definition rule in order to create a model of the part library.
This definition rule is information of the registered part library itself, and the part library is duplicated to become a template part library (step ST1).

The operator registers all the component libraries similar to "Class A" in the created "Class A" classification group (step OP2). As a result, for example, the classification group is moved or a new classification group is formed as shown in FIGS. 5 (a) to 5 (b).

The criterion for dividing into the classification groups will be further described. First, similar items are grouped. For this purpose, a template is first created to identify the group classification. Initially, a template prepared by a manufacturer is used as a base. However, if a dependency that is a criterion for grouping is clearly determined, the degree of freedom is lost, so that the user can freely classify the group.

First, it is determined that this site data is to be grouped as a representative. For example, body feature data, triangle feature data, square feature data, round feature data, straight line feature data, angle feature data, lead row feature data, round shape group feature data, missing pattern feature data Create etc.

The user takes an image of a component with the component recognition camera, and registers in advance a characteristic part of the component in the processing device. For example, in the case of an irregularly shaped part as shown in FIG. 2 (b), as a characteristic shape, for example, a circle having a diameter of 1000μ and a straight line having an angle of 90 ° are expressed in microns. A line having a length of 1000 μ ”and a line having a length of 1000 μ having an angle of 0 ° are registered. If the origin of positioning of these parts is predetermined by the manufacturer, the subsequent processing is convenient. The position is (x, y) from the origin.

For example, when the body is a square part, the size of x, y, its position, its angle, the number of leads (some of them are one), its angle, width, length, pitch , Arrangement position, etc. are registered. Which feature data to apply, or define, to these data is
This is done by the user, whereby the user can arbitrarily change the dependency of the group, that is, the affiliation of the group in the lower hierarchy, and can freely create the group according to his / her preference.

FIG. 7 is a diagram showing a template of a parts library created based on the above-described concept. Usually, although not particularly shown, the conventional parts library (parts table), for example, lists the part names in the leftmost column, lists each part of the parts in the uppermost row, and lists the parts names in the leftmost column and the respective parts in the uppermost row. In general, a tabular form having a list-like property in which features such as the shape, size, and number of a portion corresponding to a matrix grid corresponding to the portion are described.

On the other hand, the component library of the present invention does not consist of the above-described conventional table format, but includes a header part 23 and a characteristic part data part 2 as shown in FIG.
4 and the characteristic part data section 24 stores characteristic data 25 (25-1 to 25-2) of all the characteristic parts.
5-12, ..., 25-n) are described.

In the example shown in the figure, the feature part data portion 24 of the template includes triangle feature data 25-1, line feature data 25-2, corner feature data 25-3, and round feature data 25-.
4, square feature data 25-5, read feature data 25-
6, body characteristic data 25-7, shape trace characteristic data 25-8, lead group characteristic data 25-9, square group characteristic data 25-10, circle group characteristic data 25-11, and missing pattern data characteristic data 25-
It consists of 12. In addition, the user can create arbitrary feature data 25-i (i = 13 to n) as a template as needed.

Using this model, the part 11 shown in FIG. 2A has a record of one triangular feature data 25-1 and three read group feature data 25-9 ( 25-9-1, 25-9-2, 25-9
The record of -3) is created. No record is created for the other feature data 25. Then, for example, a code of “001” corresponding to the component 11 is commonly assigned to a feature code area serving as a header part of each record (feature data 25).

The part registered in the part library of the part 11 can be extracted from the part library database by reading out all the characteristic data 25 having the characteristic code of the code "001". . In the case of the parts of the “QFP” group 16 in FIG. 3, one record of one square feature data 25-5 and four read group feature data 25-9 (25-9-1 to 25-9-1)
5-9-4) are created, and in the area of the feature code serving as the header of those records (feature data 25), for example, “002” corresponding to this QFP component
Is commonly assigned.

The part registered in the part library of the QFP part can be extracted from the part library database by reading out all the characteristic data 25 having the characteristic code of "002". . Similarly, in the case of the part 12 shown in FIG.
A record of two pieces of round feature data 25-4 and a record of two pieces of line feature data 25-2 (25-2-1, 25-2-2) are created. Then, for example, a code of “003” corresponding to the component 12 is commonly assigned to the feature code area of those records.

Also in this case, in order to extract the part registered in the part library of the part 12 from the part library database, all the characteristic data 25 having the characteristic code of “003” is read. Enabled by: How to combine these feature data 25 (part data) and make them representative features of the part is left to the discretion of the operator each time. Thereby, as described above, the movement of the classification group of the component library or the new classification group can be easily performed.

FIG. 8 is a flowchart for explaining a processing operation for searching a part library by the above-described definition rule "combination of parts". In the figure, first, a user specifies a definition rule of a part to be searched. That is, a part included in the part that the user wants to search is specified (step S101).

Next, based on this designation, the definition rules (parts) of the head part library of the part library group registered as described above are searched one by one (step S102), and the searched parts are searched. It is determined whether or not the data of the designated part is included in the data of the library (step S103).

If the data of the designated part is included ("YES" in S103), the searched component library is registered as a search candidate in a predetermined search result table (step S104). Further, the number of parts included in the part library and the similarity of each part are examined, the similarity of the entire part library is calculated, and the similarity is additionally registered in the search result table (step S105).

Subsequently, it is determined whether or not all the component libraries have been searched (step S106). If all of the component libraries have not been searched yet (step S106).
106 is "No"), the process returns to step S102, and the process returns to steps S102 to S102 for the next component library.
The processing of 106 is repeated. As a result, all the component libraries including the data of the designated part are extracted in the search result table.

When all the component libraries have been searched in step S106 ("Yes" in S106), the items of each component library in the search result table are sorted in descending order of similarity (step S107). ). Thereafter, although not particularly shown, the sorting result is displayed on the display 2 or printed on paper using a printer device (not shown).

The above process is a process of searching the component library by the input component site, and the component library also registers the image of each site obtained by capturing the component with the component recognition camera. The part library can be searched using the image as a definition rule.

FIG. 9 is a flowchart of a part library search process using image images. In the figure,
First, an image of a component to be searched is specified by the user (step S201). In this process, a component is imaged by the component recognition camera, and the image is captured.

Next, the first part library of the registered part library group is designated based on the taken image image (step S202), and the image images included in the designated part library are recognized. It is executed (step S203), and it is determined whether or not the recognition of the image of the specified part is successful in the image of the component library for which the recognition has been executed (step S204).

If the recognition of the image of the specified part is successful ("Yes" in S204), the part library is registered as a search candidate in a predetermined search result table (step S205). . Further, the degree of coincidence between the recognition result of the image in the component library and the designated image is calculated, and the calculation result is additionally registered in the search result table (step S206).

Subsequently to the above, it is determined whether or not recognition has been performed for all component libraries (step S20).
7) If the recognition has not been completed for all the component libraries (S207: No), the next component library is designated (Step S208), and the process returns to Step S203 to return to the next component. The processing of steps S203 to 2107 is repeated for the library. As a result, all the component libraries including the image of the designated part are extracted in the search result table.

When all the component libraries have been recognized in step S207 ("YES" in S207), the items of each component library in the search result table are sorted in descending order by the recognition coincidence (step S207). S209). Thereafter, although not particularly shown, the sorting result is displayed on the display 2 or printed on paper using a printer device (not shown).

As described above, in the component library of the present example, the definition rule of each part of the component is determined by the user's option, and based on the definition rule, the user arbitrarily selects and specifies the part. Matching or similar parts libraries are extracted. That is, they are grouped.

By the way, the work of registering a part library including the characteristic data of a part in a database and calling a part library of a desired part from the database has been facilitated as described above. In order to create an NC program for automatic mounting on a board by using this, it is necessary to perform teaching for each component on the component mounting apparatus.

In order to perform this teaching, the position data of the parts must be accurately known. However, as described above, a part predetermined by the manufacturer is used as the reference position of the part, and the X coordinate data, the Y coordinate data, the angle data, and the like of the characteristic data in the part library shown in FIG. The description is based on the reference position. Therefore, there is no problem if the component is correctly imaged within the field of view of the component recognition camera. However, if the component is imaged at an angle, a problem occurs in that it takes too much time to align with the reference position.

In the present invention, in order to avoid this problem,
Independent of the field of view of the component recognition camera, the component has its own reference to facilitate position correction. This will be described below. 10 (a), (b) to FIG.

As shown in the figure, if the position is correctly within the field of view of the component recognition camera, the other part 27 (27-1, 27) with respect to the reference point
The relative positions of (-3, 27-4) are as described in the feature data 25 of the component library, and no problem occurs.

However, as shown in FIG.
If the camera 6 is tilted in the field of view of the component recognition camera, the image recognition processing device side, as shown in FIG. Are the relative positions of the broken line circle 27-1 'and the lower left broken line corner 27-'.
3 'and the lower right broken line angle 27-4' are determined, the actual positions shown by solid lines in the figure are not only greatly displaced but also the whole shape connecting the relative positions is distorted. I have. For this reason, there is a problem that it takes time to check the data shown by the video with the correct data.

Here, in the posture of the deformed part 26 at the correct position shown in FIG. 10B (actually, the posture is not necessarily correct as described later, but will be described at this position for convenience of description). Focusing on the left corner 27-3 and the lower right corner 27-4, assuming a straight line connecting the points P1 and P2 of these corners, the straight line is set as the X axis (or may be set as the Y axis),
The point P1 is set as the origin, and data of each part 27 is created in the parts library for this coordinate system.

Assuming that the deformed part 26 is imaged at an angle in the field of view of the part recognition camera as shown in FIGS. 11 (a) and 11 (b), as shown in FIG. It is easy to recognize the point P1 and the point P2 at those angles by recognizing 27-3 and the lower right corner 27-4. A straight line 28 connecting the recognized points P1 and P2 is set, and
With the axis (or Y axis) as the origin and the point P1 as the origin, when the view coordinates of the component recognition camera are converted to recognize the other parts, as shown in FIG. 27-
4 is correctly recognized.

The arbitrary two points for setting the straight line serving as the coordinate axis are not limited to the corner points as described above, and may be set anywhere as long as the shape is specified. . FIG. 13 is a diagram showing another example of determining arbitrary two points. As shown in the drawing, first, two arbitrary characteristic portions (in the example of the drawing, a round portion 27-1 and a U-shaped portion 27-
5) Decide. Arbitrary points P3 and P4 of the two portions, the round portion 27-1 and the U-shaped portion 27-5, are determined, and a straight line 29 connecting them is drawn. With this straight line as the X axis (or Y axis) and the point P3 (or point P4) as the origin, data of another arbitrary part is created.

Note that, in the example shown in FIG.
The center of 1 and the point P4 are set as the center of the middle line of the U-shaped portion 27-5. However, if two portions are located, any one of the two portions is unambiguous based on the relative position. It is not necessary to limit to the center, and any one of the two parts may be used.

As described above in detail, according to the present invention, the user creates data of each part in the parts library according to an arbitrary definition rule and defines the classification of the parts based on this data. This is convenient because it is possible to create a parts library suitable for user's own management and operation.

The definition rule for classifying the parts library into groups is variable, and the dependency between the upper layer classification and the lower layer classification can be changed arbitrarily. In this respect, the parts library suitable for the user's own management and operation is also used. Can be conveniently created. Further, the components may be classified as needed, and it is not necessary to always classify the components, so that management is easy.

Further, since deformed parts can also be easily classified and grouped, even if the number of kinds of deformed parts increases in the future, it is easy to manage them, which is convenient.
