Description

Inspection method, inspection system and program

The present invention belongs to the technical field related to inspection of articles on which components are mounted.

自動 Automatic visual inspection equipment is widely used as an equipment for inspecting the mounting state of components on a board. In such an apparatus, the appearance information of the board on which the component is mounted (including the board before soldering) is acquired by the sensor, and the measurement of items corresponding to the component is performed for each component. Then, by comparing the obtained result with a predetermined inspection standard, a non-defective product / defective product is determined.

Here, if the set inspection items and inspection criteria are not appropriate, it is judged that a product that is actually good is a defective product. "Missing" occurs. "Overlooking" causes deterioration of inspection efficiency, and "overlooking" lowers reliability of the manufacturing process and deteriorates work efficiency in a post-process. In addition, it is desirable to minimize “overlooking” and “overlooking” because each of these causes an increase in the cost of the manufacturing process.

However, if the inspection standards are tightened to reduce “oversight”, “oversight” will increase, and if the inspection standards are relaxed to reduce “oversight”, “oversight” will increase. Inspection items and inspection criteria need to be set.

For this reason, prior to conducting inspections on mass-produced products, inspection items and inspection standards are adjusted using verification images of boards and components, and after these adjustments are completed, the aforementioned inspection items and inspection standards are applied to actual production lines. You. However, conventionally, after adjusting the inspection items and inspection standards for all the part numbers arranged on one board, it is developed in a mass production program so that it can be executed in mass production inspection. Therefore, the quality is not constant depending on the part number. Things could also be present, and "too much" or "missing" could occur.

Here, regarding the technology that enables the reliability of data for each component to be recognized, when creating data of a component library of electronic components used in a pattern program of an electronic component mounting apparatus, the reliability is classified according to the creation state. A technology has been proposed that adds a rank-classified creation status to the data to make it possible to see at a glance which electronic components are reliable when using a component library during setup work. (See Patent Document 1). However, the above-described conventional technology does not make it possible to optimize inspection items and inspection standards in substrate inspection and the like for each component.

JP 2014-183216 A (Patent No. 6219579) JP 2008-45952 A JP 2006-250610 A JP 2001-24321 A

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to manage the quality of inspection items and / or inspection standards for each component, thereby enabling inspection items and inspections in board inspection and the like. An object of the present invention is to provide a technology that enables a standard to be optimized for each part.

た め In order to achieve the above object, the present invention employs the following configuration.

The inspection method according to the present invention is an inspection method for inspecting the article by an inspection program that determines the quality of the article on which the component is mounted,

The inspection method is characterized in that, in the determining step, quality is determined for each component based on the inspection information acquired with reference to the part number data group.

According to this, in the inspection of the article on which the parts are mounted, the inspection item and the inspection standard can be optimized for each part, and the inspection quality can be managed for each part. Further, the inspection information set for each component can be managed based on the quality level set as the inspection quality level information.

In the present invention, the inspection quality level information includes a first level indicating a high quality level and a second level indicating a low quality level,
In the setting step, when the inspection information is changed and the part number data group is updated, the inspection quality level information may be set to the second level.

According to this, if the inspection item or inspection standard is changed and the quality level of the inspection based on them is unknown, the inspection quality level information is set to the second level. Quality level can be easily checked. For example, the inspection quality level information may be set to “OK” for the first level, “NG” for the second level, and the like. Then, the user can intuitively recognize the inspection item and the quality level of the inspection standard.

Then, when the inspection information is settable by a plurality of users and the inspection quality is set to a level other than the first level (for example, “NG”) by a predetermined user, the situation is not known. The inspection quality can be prevented from being changed by another user. By doing so, it is possible to prevent the inspection items and inspection standards with low quality levels from being used for inspection unintentionally.

In the present invention, the inspection information may further include reference presence / absence information indicating whether the inspection program refers to the part number data group. Then, based on the reference presence / absence information, the inspection program can determine whether or not to perform inspection by referring to inspection items and inspection standards in the part number data group. Further, by changing the reference presence / absence information, the user can easily manage whether or not to apply the inspection items and inspection criteria in the part number data group to the actual inspection.

In the present invention, the reference presence / absence information includes ON information indicating that there is a reference to the part number data group by the inspection program, and OFF information indicating that there is no reference to the part number data group by the inspection program. Including
In the setting step, when the inspection information is changed and the part number data group is updated, the reference presence / absence information may be set to the OFF information.

According to this, when the inspection item or inspection standard is changed and the part number data group is updated, the reference presence / absence information is automatically set to OFF information, and the unchecked inspection item or inspection standard is inadvertently set to the inspection. Application can be suppressed.

In the present invention, the inspection information in the quality data group can be set by a plurality of users,
In the setting step, when the reference presence / absence information is set to the OFF information by a predetermined user, a change of the reference presence / absence information to the ON information by a user other than the predetermined user is restricted. You may.

According to this, when the inspection information is settable by a plurality of users, and when the reference presence / absence information is set to “OFF” by a predetermined user, the reference presence / absence is set by another user who does not know the circumstances. For example, it is possible to prevent information from being changed to “ON”. Then, it is possible to prevent the inspection item or the inspection standard having the low quality level from being unintentionally referred to by the inspection program, and to suppress the inspection item or the inspection standard having the low quality level from being used for the actual inspection. .

Further, in the present invention, the inspection quality level information is obtained by referring to the part number data group in a specific inspection program in addition to the first level and the second level, so that the inspection information in the part number data group can be inspected. Further including a third level indicating that the quality level is being verified,
In the setting step, when the inspection quality level information in the part number data group is changed from the third level to the first level, the reference presence / absence information may be changed to the ON information.

According to this, it is possible to easily determine that the inspection item or inspection standard in the part number data group is being confirmed by a specific inspection program. Note that the inspection quality level information at that time may be set to “TRY”, which is the third level. Further, according to this, when the inspection item or inspection standard is changed from a state being checked (for example, a state set to “TRY”) to a state showing high quality (for example, a state set to “OK”) In addition, the reference presence / absence information is automatically changed to “ON”, and a high-quality inspection item or inspection standard can be automatically applied to the inspection program.

In the present invention, the inspection quality level information can be set to a first level indicating a high quality level and a second level indicating a low quality level,
The inspection information further includes reference presence / absence information indicating presence / absence of reference to the part number data group by the inspection program,
The reference presence / absence information can be set to ON information indicating that there is a reference to the part number data group by the inspection program, and OFF information indicating that there is no reference to the part number data group by the inspection program.
In the setting step, when the inspection quality level information in the part number data group is set to the second level and the reference presence / absence information is set to the ON information,
In the determining step, the inspection of the component related to the part number data group may be performed without using the inspection program.

According to this, when the inspection item or inspection standard is set to the second level (for example, “NG”) indicating low quality and the reference presence / absence information is set to “ON”, the inspection item or inspection standard is not set. Inspection of a part to which the inspection standard is applied can be performed not by an automatic inspection by an inspection program but by a manual inspection. As a result, it is possible to suppress the occurrence of “overlooking” or “overlooking” due to automatic inspection performed based on low-quality inspection items and inspection standards, and to perform manual inspection to reduce the quality of the inspection items and inspection standards. It is possible to confirm with.

<Example 1>
Next, Embodiment 1 of the present invention will be described in detail. FIG. 3 shows an example of the product number data table 30 in the present embodiment. The part number data table 30 is created in the part number data processing unit 13 based on the information stored in the part information storage unit 22 and the inspection information storage unit 24 of the data management server 2 and output to the output unit as described above. Displayed by 101. The part number data table 30 is a table in which a part number ID corresponding to each component mounted on the board to be inspected and a part number data group corresponding to each part number ID are recorded. FIG. 3 shows a part number data group for a part 1608RS, which is a chip resistor with a part number ID001, and a part QFP4848, which is a QFP (QuadFlat Package) with a part number ID002. As described above, the combination of the part number data groups of the parts related to the plurality of part number IDs is the part number data table in the present embodiment.

Here, the part number data group of the part related to the part number ID001 will be described in detail. In the present embodiment, a shape, a component type, an inspection item, an inspection standard, and the like are recorded for the component associated with the part number ID001. The inspection criterion is a threshold or a judgment index for judging the quality of the mounted component in the inspection. Then, each time the inspection item or inspection standard is changed for the part related to the part number ID 001, the revision of the part number data group is updated and described at the top of the column corresponding to each part number ID. Regarding the part corresponding to the part number ID 001 in FIG. 3, the inspection item and the inspection standard are changed 11 times, and it can be seen that the latest revision is the revision 12.

In the part number data table of the present embodiment, the part number data group corresponding to each component includes data of the quality level and the availability of development for each revision. This quality level is an index indicating whether the quality or reliability of the inspection item or inspection standard of the product number data group in each revision is at a level that can be used for inspection by the inspection device 3. For example, a case where the quality level is NG indicates that the part number data group is being created and cannot be used for actual inspection. When the quality level is TRY, it is a part number data group in which the inspection information of inspection items and inspection standards is developed in a specific inspection program and the reliability is confirmed, and the level at which mass production can be applied soon Indicates that Further, when the quality level is OK, it is a part number data group in which inspection information of inspection items and inspection standards is developed in a specific inspection program and the reliability has been confirmed, and it is a level that can be applied to mass production. Show.

(4) The deployment availability data is an index indicating whether or not the part number data group of each revision is applied to all inspection programs. When the development availability data is OFF, the part number data group of the revision is not applied to all inspection programs. If the development availability data is ON, the part number data group of the revision is developed in all inspection programs. The development availability data can be set by the user independently of the quality level data. In FIG. 3, the quality level data corresponds to inspection quality level information. The expandability data corresponds to reference presence / absence information.

FIG. 4 shows an example of a part number reference data table for the inspection program according to the present embodiment. In the inspection system 9 according to the present embodiment, a plurality of components are inspected on the board by using a plurality of inspection programs as described above. FIG. 4 shows part number reference data tables 35a and 35b for inspection programs 1 and 2 among many inspection programs. In the part number reference data tables 35a and 35b, the circuit IDs assigned to the plurality of circuits on the board, the part numbers of the parts mounted on the circuits assigned with the circuit IDs, and the mounting positions of the parts assigned with the part number IDs , A reference revision which is a revision to be referenced in the part number data group related to each part number ID, a quality level in the reference revision part number data group, expandability, a latest revision of the part number data group related to each part number ID, a part number data group of the latest revision , The status of the part number development, which is the state of the part number data group, is displayed.

According to the part number reference data table 35a for the inspection program 1 shown in FIG. 4A, the parts corresponding to the part number ID001 are used in the circuits corresponding to the circuit IDs 1 to 4, and the mounting position of the part on the board is determined. It can be seen that they are Left and Top, and that the latest revision of the part number data group for the part is revision 12. Further, the part number data group of the revision 12 is currently NG as the quality level, but the ON / OFF is set as to whether or not the development is possible, and it can be seen that the update is necessary. In addition, the inspection program 1 refers to the part number data group of the revision 9 instead of the part number data group of the latest revision. The part number data group of the revision 9 is currently OK as the quality level, and the deployment possibility is ON. You can see that there is.

In other words, in the inspection system 9 according to the present embodiment, the inspection items and the inspection criteria for each component on the board are managed by a part number data group. The part number data group is managed for each revision, along with the inspection items and inspection standards, the quality level of the part number data group itself, and whether or not it can be developed. A part number data group referred to in each inspection program is managed by a part number reference data table.

Next, referring to FIG. 5, a description will be given of a management flow of the quality level of the part number data group and the contents of the possibility of development in the inspection system 9 of the present embodiment. This flow may be stored in the memory 103 of the control terminal 1, and all steps are automatically executed when an input to create a new part number data group is made from the input unit 102. It may be. FIG. 5 is a flowchart of the inspection information management routine. When this flow is executed, first, in step S101, a part number is created for a new inspection target component. When a product number is created, a product number data group corresponding to the product number is generated. In the part number data group in this state, the part number level is set to NG, and the availability is set to OFF.

In step S102, a window screen corresponding to the created part number data group is automatically created and displayed on the output unit 101 of the control terminal 1. Further, in addition to the good part model image and the defective part result image of the part corresponding to the part number data group created in step S103, the part information, the part shape, the part type, the inspection item and the inspection reference temporarily set at the present time, and the like are stored. 22. As a result, the product name, shape, component type, inspection item, inspection standard, and the like in the product number data table 30 of FIG. 3 are displayed.

Next, in step S104, a verification image is registered. More specifically, a sample image for pre-verification as to whether “overlooking” or “overlooking” occurs according to the inspection item and inspection standard registered in the process of step S103 is registered. When the process in step S104 ends, the process proceeds to step S105. In step S105, a product number adjustment is performed. That is, the inspection item and the inspection standard that are considered appropriate are adjusted with respect to the verification image registered in step S104. When the process in step S105 ends, the process proceeds to step S106.

In step S106, it is determined whether or not “overlooked” or “missed” has not occurred on the verification screen registered in step S104. Here, if "overlooking" or "overlooking" occurs, it is determined that the inspection item or inspection standard in the part number data group is not appropriate, so that the process returns to the process of step S105, and further adjustment of these items is performed. Is performed. Then, in step S106, the processing of steps S105 and S106 is repeated until neither "overlooking" nor "missing" occurs on the verification screen.

に お い て If no “overlook” or “overlook” has occurred in the verification screen in step S106, the process proceeds to step S107. In step S107, the quality level is changed to TRY by the user. When the process in step S107 ends, the process proceeds to step S108. In step S108, the part number data group is applied to a specific inspection program. More specifically, a specific inspection program to which the part number data group is applied may be specified in another window displayed on the output unit 101. As a result, in the part number reference data table of the specific inspection program, whether or not development is possible is set to ON corresponding to the part number data group. In addition, the specific inspection program may be one or two or more.

す る と When the process of step S108 ends, the process proceeds to step S109. In step S109, a board inspection is performed in the inspection apparatus 3 using the inspection program subjected to the processing applied in step S108. Then, in step S110, it is determined whether or not “too much” or “missing” has occurred in the inspection performed in step S109. If it is determined that “overlook” or “overlook” has occurred, the process returns to step S109, and the inspection items and inspection standards are adjusted again. On the other hand, when it is determined that “too much” or “missing” does not occur, the process proceeds to step S111.

In step S111, the part number data is applied to a larger number of inspection programs, and the inspection device 3 performs a plurality of inspections. When the process in step S111 ends, the process proceeds to step S112. Then, in step S112, it is determined whether "overlooking" or "missing" has occurred in the plurality of inspections in step S111. If "too much" or "missing" has occurred in step S112, the process returns to step S111, and the inspection items and inspection standards are adjusted again. On the other hand, if it is determined that “too much” or “missing” does not occur, the process proceeds to step S113.

(4) In step S113, the quality level in the part number data group is set to OK, and whether or not development is set to ON. As a result, the part number data group is applied to all inspection programs to which the part number data group should be referred. When the process in step S113 ends, the present routine ends once. Steps S101, S107, and S113 of the inspection information management routine according to the present embodiment correspond to setting steps. Steps S106, S110, and S112 correspond to a determination step.

(5) The right side of the flowchart shown in FIG. 5 shows the setting of the quality level and the possibility of development in the part number data group at the stage when each step is executed. According to this, when a new product number is created in step S101, the quality level is set to NG, and the availability is set to OFF. Thereafter, in the adjustment of the part number data group using the verification image in step S105, if "overlooking" or "missing" has not occurred, in step S107, the quality level is set to TRY and the development possibility is set to OFF. Is set. Then, if “overlooking” or “overlooking” has not occurred in the plurality of inspection programs, in step S113, the quality level is set to “OK” and the development possibility is set to “ON”.

FIG. 6 shows changes in the part number reference data table when the examination of the inspection items and inspection standards of the part number data group is advanced and the quality level of the part number reaches OK, as described in the above flow. FIG. 6 shows a part number reference data table for the inspection programs 1 and 2.

6 (a), the inspection program 1 refers to the revision 5 and the inspection program 2 refers to the revision 6 for the part associated with the part number ID001. In revision 5, the quality level of the part number data group is set to TRY, and in revision 6, the quality level of the part number data group is set to OK. In addition, it can be seen that in both the revision 5 and the revision 6, the deployment availability is set to ON. As for the part number data group of the part having the part number ID 001, the latest revision is the revision 7, the quality level of the revision 7 has already been set to OK, and the availability of the development has already been set to ON. That is, it can be seen that the revision 7 is a completed product number data group.

で In this state, the latest revision is applied to all the inspection programs for the item number data group of item number ID001. More specifically, another window may be displayed on the output unit 101, and an instruction to apply the latest reference revision for the inspection program 1 may be executed in the another window. Then, as shown in FIG. 6B, in the inspection program 1 and the inspection program 2, the part number data group of the latest revision 7 is referred to, and the quality level is changed to OK. . As described above, in the present embodiment, the completed part number data group can be collectively applied to all inspection programs, and the optimum inspection items and inspection standards can be efficiently applied. ing.

In the present embodiment, when the inspection system 9 is enabled by a plurality of users, when the quality level of the part number data group is set to NG or TRY by a specific user, the quality is set by another user. The change of the level to OK may be restricted. More specifically, the quality level may be prohibited from being changed to OK by a user other than the specific user at all, or may be changed only by a specific other user, for example, the manager of the specific user. May be permitted.

Similarly, when the inspection system 9 is available for use by a plurality of users, if the development permission / prohibition of the part number data group is set to OFF by a specific user, the development permission / prohibition is changed to ON by another user. May be restricted. More specifically, it is possible to completely prohibit the deployment permission / prohibition from being changed to ON by a user other than the specific user, or to be changed only by a specific other user, for example, the manager of the specific user. May be permitted.

(4) This prevents a user who does not know the circumstances from changing the quality level of the product number data group and the setting contents of whether or not it can be developed. By doing so, it is possible to prevent the inspection items and inspection standards with low quality levels from being used for inspection unintentionally.

<Example 2>
Next, a second embodiment of the present invention will be described. In the second embodiment, a description will be given of a process in a case where “missing” occurs in the manufacturing process in a state where the part number data group whose reliability has been confirmed is already applied to all the inspection programs. FIG. 7 is a flowchart showing a process of the inspection information management routine 2 executed when “missing” occurs during inspection in a state where the item number level in the item number data group is set to “OK” and the development possibility is set to “ON”. It is. This flow may be stored in the memory 103 of the control terminal 1, or may be automatically executed when the “missing” detection data is transmitted from the inspection device 3. In addition, regarding the step in which the manual inspection is performed, the inspection program may be in a state of waiting for a result input from an operator.

When this routine is executed, first, in step S201, it is detected that "missing" at the time of inspection has occurred. In this case, there is a risk that the defective product will pass through without being found in the process, so urgent action is required. Therefore, in step S202, the quality level of the product number data group is set to NG. When the process in step S202 ends, the process proceeds to step S203.

(4) In step S203, the part number data group is applied to all inspection programs. In this case, in all the inspection programs, a part number data group having a quality level of NG is applied. In such a case, the inspection system 9 according to the present embodiment stops the automatic inspection by the inspection program and performs the manual inspection for the inspection referring to the part number data group in which “missing” has occurred. As the display at that time, the quality of the product number may be simply displayed as NG in the window related to the product number data group displayed on the output unit 101 in the inspection system 9 or some other alert display may be performed. Good. When the process in step S203 ends, the process proceeds to step S104.

The difference between the processing of steps S104 to S113 and the inspection information management routine shown in FIG. 5 is that in the processing of step S206, there was no "overlooking" or "missing" for the verification screen registered in step S104. Is determined by a manual inspection. Further, in step S210, it is determined whether or not “too much” or “missing” has occurred in the inspection performed in step S109 by a manual inspection. In step S212, it is determined whether or not “overlooking” or “overlooking” has occurred in the plurality of inspections in step S111 by a manual inspection.

FIG. 8 illustrates an inspection system control routine for performing a manual inspection when “overseeing” occurs in the manufacturing process as described above. This flow may be stored in the inspection program storage unit 23, or may be executed when the inspection is performed by the inspection device 3. When this routine is executed, first, in step S301, an inspection program is read. When step S301 ends, the process proceeds to step S302. In step S302, a part number data group referred to in the inspection program read in step S301 is read. When the process in step S302 ends, the process proceeds to step S303. In step S303, an inspection image is obtained. Then, an inspection is performed in step S304.

Next, in step S305, it is determined whether the quality level in the product number data group is set to OK. Here, if the quality level in the part number data group is set to OK, the process proceeds to step S309, and an automatic inspection is performed. On the other hand, if it is determined in step S305 that the quality level in the product number data group is not set to OK, the process proceeds to step S306. In step S306, it is determined whether or not the quality level of the product number data group is set to TRY. Here, if it is determined that the quality level is set to TRY, the process proceeds to step S309, and an automatic inspection is performed. On the other hand, if it is determined that the quality level is not set to TRY, the process proceeds to step S307.

In step S307, it is determined whether or not the quality level of the product number data group is set to NG. Here, when it is determined that the quality level of the part number data group is set to NG, the process proceeds to step S308, and a manual inspection is performed. On the other hand, if it is determined that the quality level is not set to NG, the process proceeds to step S309, and an automatic inspection is performed. When the automatic inspection in step S309 or the manual inspection in step S308 ends, the process proceeds to step S310.

に お い て In step S310, it is determined whether the inspection has been completed. If it is determined in step S310 that the inspection has been completed, the present routine ends once. If it is determined that the inspection has not been completed, the process returns to step S304, and the inspection is continued. In this routine, if there are only three types of quality level data of the part number data group, “OK”, “TRY”, and “NG”, in step S306, the quality level of the part number data group is “TRY”. If it is determined that there is not, the process may proceed directly to step S308.

FIG. 9 shows an example of changing the part number reference data table when “missing” occurs in the inspection system 9 as described in FIGS. 7 and 8. 9A, the part number data group of the revision 9 is referred to in the inspection program 3 and the part number data group of the revision 10 is referred to in the inspection program 3 for the part having the part number ID 003. Then, it can be seen that the quality level is set to OK and the availability of development is set to ON for both revision 9 and revision 10. For the part number data group of the part having the part number ID 003, the latest revision is the revision 12, and the quality level of the revision 12 is set to NG. Then, it can be seen that the status of the part number development is "update required".

In this state, if “missing” occurs in the inspection in any of the inspection programs, urgent action is required, and as shown in FIG. 9B, the part with the part number ID 003 is forcibly updated to the latest. The part number data of the revision 12 is referred to. Then, the quality level is set to NG. Then, as shown in step S307 and step S308 in FIG. 8, for the part having the part number ID001, not the automatic inspection but the manual inspection is performed. Then, the status of the part number development is displayed as “overlooked”.

Accordingly, when "missing" occurs in the inspection system 9, the automatic inspection can be stopped in an emergency evacuation and the manual inspection can be performed. Then, it is possible to continue optimizing the inspection items and inspection standards in the part number data group without affecting the inspection quality in the manufacturing process. In this embodiment, if “missing” occurs in the inspection in any inspection program, the part number data group of the latest revision whose quality level is NG may be automatically referred to, or the output unit Even if the user can manually display the part number data group of the latest revision whose quality level is NG on all inspection programs, the user can manually refer to the part number data group of the latest revision whose quality level is NG. Good. In the above-described application examples and embodiments, the example has been described in which the part number data group is revision-managed and a new revision is created when the inspection information is changed. However, the present invention is also applied to the case where the part number data group is only rewritten when the inspection information is changed and the part number data group of a new revision is not created, that is, the case where the part number data group is not revision-managed. Of course it is possible.
