Description

This specification relates to a component mounting system that performs the mounting work of mounting components on a board.

The technology of mass-producing board products by performing substrate-related operations on boards on which circuit patterns are formed has become widespread. Furthermore, it has become common to configure a component mounting line by arranging other types of substrate-related operation machines in front of and behind a component mounting machine that performs component mounting operations. In a component mounting line, unique information is usually set for each type of board or each individual board, and the component mounting machine and other substrate-related operation machines share the unique information and perform operations based on this information. One example of a technology related to sharing information in a component mounting line is disclosed in Patent Document 1.

The board production line disclosed in Patent Document 1 includes multiple board production machines (machines for performing work on boards) and a shared holder, and creates a board type information file in the shared holder, which includes information on the board type identified by the most upstream board production machine, and board production machines other than the most upstream recognize the board type information file. It is further disclosed that the board type information file includes individual identification information for the board, a terminate flag indicating the end of production of the board, and skip information indicating that some of the small board pieces of a multi-panel board cannot be used. According to this, since the board type information file is recognized by downstream board production machines in response to the transport of the board, each board production machine can easily use the shared holder to understand information such as the board type, even if they do not have a communication function between each other.

International Publication No. 2018/109948

In Patent Document 1, the multiple board production machines that make up a board production line are able to commonly recognize information such as board type by recognizing the board type information file in the shared holder. However, when the component mounting work is shared among multiple component mounting lines (board production lines), the shared holder is provided on a line-by-line basis, so information cannot be shared across lines, which can lead to the following problems:

For example, consider a case where a first component mounting line performs mounting work on the top surface of a double-sided mounting type board, and a second component mounting line performs mounting work on the bottom surface of the same board. In this case, even if a problem occurs in the mounting work on the top surface and skip information is set for a specific board indicating that it cannot be used, the second component mounting line will not be able to recognize this skip information. As a result, there is a risk that the second component mounting line will perform unnecessary mounting work on the bottom surface of the board for which skip information has been set. To eliminate this risk, worker judgment and action are required.

Therefore, the problem to be solved in this specification is to provide a component mounting system that can share instruction information regarding component mounting work among multiple component mounting lines and automatically perform appropriate mounting work.

This specification discloses a component mounting system that includes a shared memory unit that stores instruction information representing instructions for performing a mounting operation to mount components on a board, the instruction information being set for each individual board, and a plurality of component mounting lines that share the instruction information stored in the shared memory unit and share the mounting operation in accordance with the instruction information.

In the disclosed component mounting system, multiple component mounting lines share the instruction information stored in the shared memory unit, so they can also commonly recognize when the instruction information has been changed. Therefore, multiple component mounting lines can automatically perform appropriate mounting work according to the latest instruction information set for each individual board.

1. Multiple board K, unique information ID, mounting operation data DP
1 to 3, a description will be given of a board on which components are mounted by the component mounting system 1 of the first embodiment, the board's unique information ID, and mounting operation data DP used by the component mounting system 1. An example of the target board is the multiple board K shown in FIG.

Multiple-panel board K consists of six small board pieces (KS1, KS2, KS3, KS4, KS5, KS6) arranged in a 2 x 3 array, and a surrounding frame KW. As shown by the dashed lines in Figure 1, each of the small board pieces (KS1 to KS6) is removed from the frame KW after components are mounted, and then separated from each other and used as separate board products. Multiple-panel board K is a double-sided mounting type, and mounting is performed once on the top surface (front surface) and once on the bottom surface (back surface).

Position reference marks M are provided near two opposing corners of the frame portion KW. Unique information ID is provided near the third corner of the frame portion KW. The position reference marks M and unique information ID are provided on both the top surface and the bottom surface. Furthermore, the position reference marks M and unique information ID may be additionally provided on each of the small substrate pieces (KS1 to KS6).

The unique information ID identifies each individual multi-panel board K. The unique information ID is written, for example, using a character string or a barcode. The unique information ID is also provided by attaching a label or stamping (impressing a seal). The format of the unique information ID shown in FIG. 2 is made up of a manufacturer field MF, a board type field SR, an individual number field NO, and a surface information field FI.

The manufacturer field MF is written, for example, with two English letters, and indicates the manufacturer of the multi-panel substrate K. The substrate type field SR is written, for example, with four alphanumeric characters, and indicates the type of multi-panel substrate K. The individual number field NO is written, for example, with a six-digit serial number, and indicates an individual multi-panel substrate K. The surface information field FI is written, for example, with an alternative between "T" indicating the top surface and "B" indicating the bottom surface. The format of the unique information ID is not limited to the above, and there are various variations.

The mounting work data DP used by the component mounting system 1 has, for example, the format illustrated in FIG. 3. The data name DN of the mounting work data DP is created by concatenating the contents of the manufacturer column MF and the board type column SR. In the mounting work data DP, the serial number in the individual number column NO (one multi-panel board K) is associated with multiple pieces of information, and each association is written on a single line. The multiple pieces of information include top surface finish information TZ, top surface order information TN, bottom surface finish information BZ, bottom surface order information BN, and six pieces of instruction information (C1 to C6). This information is changeable.

The top surface completion information TZ and bottom surface completion information BZ are alternatively indicated as "0", indicating that the mounting work on the relevant surface has not been completed, or "1", indicating that the mounting work has been completed. The top surface order information TN and bottom surface order information BN indicate the order in which the mounting work on the relevant surface is to be performed. The substrate-related processing machine can search for the top surface order information TN and bottom surface order information BN corresponding to the order in which the multi-panel substrate K is carried in, and can refer to the information on the substrate without making a mistake. This prevents confusion even if the multi-panel substrate K is carried in in an order that differs from the serial numbers in the individual number column NO, and even if multiple mounting operations are attempted on one surface of one multi-panel substrate K.

Each of the six pieces of instruction information (C1-C6) corresponds to one of the six small board pieces (KS1-KS6). The six pieces of instruction information (C1-C6) are alternatively represented as implementation information "0", which indicates that mounting work will be performed on the small board pieces (KS1-KS6), and skip information "1", which indicates that mounting work will not be performed. In the initial state of mounting work data DP before mounting work on the multiple board K begins, the top surface end information TZ, top surface order information TN, bottom surface end information BZ, bottom surface order information BN, and the six pieces of instruction information (C1-C6) for all individual number column NOs are all represented as "0" (see Figure 3).

2. Configuration of component mounting system 1 of the first embodiment Next, the configuration of component mounting system 1 of the first embodiment will be described with reference to FIG. 4. Component mounting system 1 is composed of a shared memory unit 2, a first component mounting line 3, a first line-specific memory unit 4, a second component mounting line 5, and a second line-specific memory unit 6. The first component mounting line 3 and the second component mounting line 5 have the same line configuration. The first component mounting line 3 and the second component mounting line 5 share instruction information (C1 to C6) stored in the shared memory unit 2, and share and perform mounting work in accordance with the instruction information (C1 to C6). In addition, the first component mounting line 3 and the second component mounting line 5 can also perform separate mounting work for different types of boards.

The first component mounting line 3 is composed of six board-related work machines lined up. That is, a solder printer 31, a solder inspection machine 32, a component mounting machine 33, a first board visual inspection machine 34, a second board visual inspection machine 35, and a reflow machine 36 are lined up in the order shown. Each of the six board-related work machines carries in a board from the upstream side, performs a specified board-related work on the board, and carries out the board downstream after the board-related work has been completed. Board-related work includes component mounting work and is a term that encompasses related work before and after mounting work.

The solder printer 31 prints solder paste at a specified location on the board. The solder inspection machine 32 inspects the printing condition of the solder paste. The component mounting machine 33 mounts components onto the solder paste. The first board visual inspection machine 34 and the second board visual inspection machine 35 share the task of inspecting the mounting condition of multiple components. The reflow machine 36 heats and melts the solder paste, then cools and solidifies it, stabilizing the soldered condition of the components (reflow operation). The six board-related work machines are not equipped with communication devices for communicating with each other. Therefore, the six board-related work machines cannot transmit information between each other using communication.

The second solder inspection machine 32 from the upstream side has a unique information acquisition unit 37 that acquires a unique information ID that identifies an individual multi-panel board K. Examples of the unique information acquisition unit 37 include a camera or a barcode reader that is placed above the entrance through which the multi-panel board K is brought in. The camera captures and acquires the unique information ID provided on the multi-panel board K, and the barcode reader reads and acquires the unique information ID.

The second component mounting line 5 is composed of a solder printer 51, a solder inspection machine 52, a component mounting machine 53, a first board visual inspection machine 54, a second board visual inspection machine 55, and a reflow machine 56, arranged in the order listed. The solder inspection machine 52 has a unique information acquisition unit 57. Note that the first component mounting line 3 and the second component mounting line 5 may have a line configuration different from that described above. Also, the first component mounting line 3 and the second component mounting line 5 may have a line configuration different from each other.

The shared memory unit 2 stores the mounting work data DP described above. That is, the shared memory unit 2 stores a unique information ID that identifies an individual multi-panel board K in association with the instruction information (C1 to C6). The shared memory unit 2 may be a simple storage device, or may be part of a computer system equipped with a CPU. The mounting work data DP can be accessed (obtained by reading, set or changed by writing) by a specific board-related operation machine. In the first embodiment, the mounting work data DP can be read and obtained by the solder inspection machine (32, 52), and written and set by the second board visual inspection machine (35, 55).

The shared memory unit 2 receives information corresponding to the minimum and maximum values of the manufacturer column MF, board type column SR, and individual number column NO of the unique information ID of the multi-panel board K from the higher-level device 21. The value obtained by subtracting the minimum value from the maximum value of the individual number column NO and adding 1 indicates the number of multi-panel boards K to be produced. In this way, the initial state mounting work data DP is created. The higher-level device 21 corresponds to a production management system that manages production plans for multiple types of boards.

The first line-specific memory unit 4 stores first reference data DQ1. The first reference data DQ1 has the same data structure as the mounting work data DP. The first reference data DQ1 is written by the solder inspection machine 32 and read by the second board visual inspection machine 35. The first reference data DQ1 is also referenced by the component mounting machine 33, the first board visual inspection machine 34, and the second board visual inspection machine 35. Furthermore, the first reference data DQ1 is changed as necessary by the solder inspection machine 32, the first board visual inspection machine 34, and the second board visual inspection machine 35.

The second line-specific memory unit 6 has the same memory capacity as the first line-specific memory unit 4, and has the same functions. That is, the second line-specific memory unit 6 stores second reference data DQ2. The second reference data DQ2 has the same data structure as the mounting work data DP. The second reference data DQ2 is written by the solder inspection machine 52 and read by the second board visual inspection machine 55. The second reference data DQ2 is also referenced by the component mounting machine 53, the first board visual inspection machine 54, and the second board visual inspection machine 55. Furthermore, the second reference data DQ2 is changed as necessary by the solder inspection machine 52, the first board visual inspection machine 54, and the second board visual inspection machine 55.

3. Operation of component mounting system 1 of the first embodiment Next, the operation of component mounting system 1 of the first embodiment will be described with reference to Figs. 5 and 6. Hereinafter, it is assumed that first, the first component mounting line 3 performs substrate-related work on the top surface of the multiple board K, and then, the second component mounting line 5 performs substrate-related work on the bottom surface of the multiple board K. Both the first component mounting line 3 and the second component mounting line 5 operate according to the operation flow shown in Fig. 5. This operation flow is performed for each individual piece of the multiple board K. Before the start of operation, mounting operation data DP for the initial state has already been created.

When the top surface of the multi-panel board K is carried in, the first component mounting line 3 performs work on the board, including the mounting work. Here, the order in which the multi-panel board K is carried in is the order of "000002", "000001", and "000003" in the individual number column. In step S1 of FIG. 5, the solder printer 31 prints solder paste on the top surface of the carried-in multi-panel board K without recognizing the information corresponding to the individual number column. At this time, the solder printer 31 uses a screen that covers six small board pieces (KS1 to KS6) and a squeegee that moves over the screen. The printed multi-panel board K is then carried out and transported to the solder inspection machine 32.

In the next step S2, the solder inspection machine 32 uses the unique information acquisition unit 37 to acquire the unique information ID of the first multiple board K. In the next step S3, the solder inspection machine 32 reads and acquires information for the relevant row of the mounting work data DP from the shared memory unit 2 based on the individual number field NO (=000002) included in the unique information ID, and writes this information to the first reference data DQ1 in the first line-specific memory unit 4 (acquisition process). Furthermore, the solder inspection machine 32 sets the top surface order information TN for the relevant row of the first reference data DQ1 to "1", which is equal to the carry-in order.

In the next step S4, the solder inspection machine 32 inspects the printing condition of the paste solder. If the printing condition is good and the inspection result is a pass, the operation flow proceeds to step S6, and if the inspection result includes a fail, the operation flow proceeds to step S6 via step S5. It is assumed that the inspection result of the first multi-panel board K is a pass.

In step S6, the component mounting machine 33 mounts the components on the solder paste. Prior to the mounting operation, the component mounting machine 33 determines whether or not to perform the mounting operation according to the instruction information (C1 to C6). In detail, the component mounting machine 33 refers to the instruction information (C1 to C6) of the corresponding row in the individual number column NO (=000002) of the first reference data DQ1 in which the top surface order information TN corresponding to the first in the loading order is "1". If the instruction information (C1 to C6) includes skip information "1", the component mounting machine 33 skips the mounting operation on the small board (KS1 to KS6) corresponding to the skip information "1". The substrate operation machine can refer to the corresponding row of the first reference data DQ1 without making a mistake, based on the top surface order information TN corresponding to the loading order of the multi-panel board K.

In the next step S7, the first board visual inspection machine 34 and the second board visual inspection machine 35 share the task of inspecting the mounting state of multiple components. At this time, the first board visual inspection machine 34 and the second board visual inspection machine 35 refer to the instruction information (C1 to C6) in the same way as the component mounting machine 33, and skip the inspection of the small board pieces (KS1 to KS6) corresponding to the skip information "1". If the mounting state is good and the inspection result is a pass, the operation flow proceeds to step S9, and if the inspection result includes a fail, the operation flow proceeds to step S9 via step S8. It is assumed that the inspection result of the first multiple board K was a pass.

In step S9, the second board visual inspection machine 35 sets the top surface completion information TZ of the corresponding row in the individual number column NO (=000002) of the first reference data DQ1 to "1", indicating that the mounting work has been completed. Furthermore, the second board visual inspection machine 35 reads the information of the corresponding row, transfers this information to the shared memory unit 2, and writes it into the mounting work data DP (transfer process). In the next step S10, the reflow machine 36 performs the reflow work on the multiple board K.

While the substrate-to-substrate operation is being performed on the top surface of the first multi-panel board K, the top surface of the second multi-panel board K is brought into the solder printer 31, where paste solder is printed in step S1. In the next step S2, the solder inspection machine 32 acquires the unique information ID using the unique information acquisition unit 37. In the next step S3, the solder inspection machine 32 reads and acquires the information of the corresponding row of the mounting work data DP based on the individual number field NO (=000001) included in the unique information ID, and writes this information to the first reference data DQ1 (acquisition process). Furthermore, the solder inspection machine 32 sets the top surface order information TN of the corresponding row of the first reference data DQ1 to "2", which is equal to the carry-in order.

In the next step S4, the solder inspection machine 32 inspects the printing state of the paste solder. In the second multiple board K, the third small board KS3 is deemed to have failed, and the other small boards (KS1, KS2, KS4 to KS6) are deemed to have passed. In other words, the third small board KS3 cannot be used as a board product. Therefore, in step S5, the solder inspection machine 32 changes the implementation information "0" of the third instruction information C3 in the corresponding row of the individual number column NO (=000001) of the mounting work data DP to skip information "1". In step S6, the component mounting machine 33 refers to the instruction information (C1 to C6), skips the mounting work on the third small board KS3, and performs the mounting work on the other small boards (KS1, KS2, KS4 to KS6).

In the next step S7, the first board visual inspection machine 34 and the second board visual inspection machine 35 skip the inspection of the third small board KS3 and inspect the other small boards (KS1, KS2, KS4 to KS6). Assume that the inspection results of the five small boards (KS1, KS2, KS4 to KS6) of the second multiple board K are passed. In step S9, the second board visual inspection machine 35 sets the top surface completion information TZ of the corresponding row in the individual number column NO (=000001) of the first reference data DQ1 to "1", indicating that the mounting work has been completed. Furthermore, the second board visual inspection machine 35 reads the information of the corresponding row and writes this information to the mounting work data DP (transfer process). In the next step S10, the reflow machine 36 performs the reflow work on the multiple board K.

Then, the top surface of the third multiple board K is loaded into the solder printer 31, and paste solder is printed in step S1. In the next step S2, the solder inspection machine 32 acquires the unique information ID using the unique information acquisition unit 37. In the next step S3, the solder inspection machine 32 reads and acquires the information of the corresponding row of the mounting work data DP based on the individual number field NO (=000003) included in the unique information ID, and writes this information to the first reference data DQ1 (acquisition process). Furthermore, the solder inspection machine 32 sets the top surface order information TN of the corresponding row of the first reference data DQ1 to "3", which is equal to the load order.

In the next step S4, the solder inspection machine 32 inspects the printing condition of the paste solder. The inspection result for the third multiple board K is assumed to be pass. In step S6, the component mounting machine 33 refers to the instruction information (C1 to C6) and performs mounting work on all small board pieces (KS1 to KS6).

In the next step S7, the first board visual inspection machine 34 and the second board visual inspection machine 35 inspect all the small boards (KS1 to KS6). In the third multiple board K, the fifth small board KS5 has failed, and the other small boards (KS1 to KS4, KS6) have passed. In other words, the fifth small board KS5 cannot be used as a board product. Therefore, in step S8, the first board visual inspection machine 34 or the second board visual inspection machine 35 sets skip information "1" to the fifth instruction information C5 of the corresponding row in the individual number column NO (=000003) of the first reference data DQ1.

In the next step S9, the second board visual inspection machine 35 sets the top surface completion information TZ of the corresponding row in the individual number column NO (=000003) of the first reference data DQ1 to "1", indicating that the mounting work has been completed. Furthermore, the second board visual inspection machine 35 reads the information of the corresponding row and writes this information into the mounting work data DP (transfer process). In the next step S10, the reflow machine 36 performs the reflow work on the multiple board K.

At this point, the first reference data DQ1 stored in the first line-specific memory unit 4 is in the state shown in FIG. 6. As shown, for the first through third multiple boards brought in, the top surface finish information TZ is set to "1" and the top surface sequence information TN is set to 1-3. Furthermore, skip information "1" is set in the third instruction information C3 in the row with the individual number field NO of 000001 and the fifth instruction information C5 in the row with the individual number field NO of 000003. Also, due to the transfer process of the second board visual inspection machine 35, the mounting work data DP stored in the shared memory unit 2 is in the same state as the first reference data DQ1.

Next, the bottom surfaces of the first to third multi-panel boards K are carried into the second component mounting line 5, and the substrate-related work is carried out. At this time, the order in which the multiple multi-panel boards K are carried into the second component mounting line 5 may differ from the order in which they are carried into the first component mounting line 3. The same substrate-related work is carried out in the second component mounting line 5 as in the first component mounting line 3. As the substrate-related work progresses, information in each row of the mounting work data DP (information shown in FIG. 6) is read out and written to the second reference data DQ2 in the second line-specific memory unit 6 (acquisition process).

The solder inspection machine 52, the component mounting machine 53, the first board visual inspection machine 54, and the second board visual inspection machine 55 of the second component mounting line 5 refer to the second reference data DQ2 and omit the work on the small boards (KS1 to KS6) for which the skip information "1" is set. In other words, these board-related work machines omit the work on the small boards (KS1 to KS6) that cannot be used as board products. Specifically, the work on the third small board KS3 of the multiple board K whose individual number column number is 000001 and the fifth small board KS5 of the multiple board K whose individual number column number is 000003 are omitted. However, since the solder printing machine 51 uses a screen, it is not possible to selectively omit printing on some of the small boards (KS1 to KS6).

The second reference data DQ2 is changed in response to the execution of the work on the board in the second component mounting line 5. Specifically, the bottom side sequence information BN and the bottom side end information BZ are set. Furthermore, the skip information "1" is changed and set in response to the failure of the inspection results of the solder inspection machine 52, the first board visual inspection machine 54, and the second board visual inspection machine 55.

In addition, the transfer process of the second board visual inspection machine 55 causes the mounting work data DP stored in the shared memory unit 2 to become the same as the second reference data DQ2. When the work on the top and bottom surfaces of all the multiple boards K is completed, the first reference data DQ1 and the second reference data DQ2 are erased. On the other hand, the mounting work data DP is saved to improve the traceability of the board products.

4. Functions and Effects of the Component Mounting System 1 of the First Embodiment Next, the functions and effects of the component mounting system 1 of the first embodiment will be described in comparison with the component mounting system 1X of the prior art. As shown in FIG. 7, the component mounting system 1X of the prior art does not include a shared memory unit 2, and is composed of a single component mounting line 3X and a memory unit 4X. In the component mounting system 1X of the prior art, the component mounting line 3X first performs a substrate-related operation on the top surface of the multiple substrate K, and appropriately sets skip information "1" to the mounting operation data DP in the memory unit 4X. Next, the component mounting line 3X performs a substrate-related operation on the bottom surface of the multiple substrate K while referring to the mounting operation data DP.

Therefore, the conventional component mounting system 1X performs the board-related operations on the top and bottom surfaces in series, which lengthens the time required for the operations. Furthermore, even if another component mounting system is used to perform the board-related operations on the bottom surface, the other component mounting system cannot recognize the mounting operation data DP, which is changed successively. Therefore, if the board-related operations on the top and bottom surfaces are forcibly performed in parallel, unnecessary mounting operations will be performed on small board pieces (KS1-KS6) that have failed inspection. This results in losses from the waste of components, and the time required for the operations is lengthened by the amount of unnecessary board-related operations.

In contrast, in the component mounting system 1 of the first embodiment, a multi-panel board K for which substrate-related work has been completed on the first component mounting line 3 can be carried into the second component mounting line 5. At this time, information about the multi-panel board K is transferred from the first reference data DQ1 to the second reference data DQ2 via the mounting work data DP. Therefore, the second component mounting line 5 can correctly determine whether or not to perform substrate-related work by referring to the latest status of whether or not skip information "1" is set in the instruction information (C1 to C6).

It is also possible to perform substrate work on the top surfaces of half of the multi-panel substrates K on the first component mounting line 3 while performing substrate work on the bottom surfaces of the remaining half of the multi-panel substrates K on the second component mounting line 5, and then replace the multi-panel substrates K that have already been worked on and perform the remaining substrate work. In any case, according to the first embodiment, substrate work on the top and bottom surfaces can be performed in parallel, shortening the time required for work.

In addition, the first component mounting line 3 and the second component mounting line 5 share the instruction information (C1-C6) stored in the shared memory unit 2, and can therefore commonly recognize when the instruction information (C1-C6) has been changed. Therefore, the first component mounting line 3 and the second component mounting line 5 can automatically perform appropriate mounting work according to the latest instruction information (C1-C6) set for each individual multiple board K.

This method skips the installation work on small board pieces (KS1 to KS6) that cannot be used as board products, so parts are not wasted and it is economical. In addition to skipping the installation work, meaningless board-related work such as inspection can be omitted, which reduces the time required for work.

5. Component mounting system 1A according to the second embodiment
Next, a component mounting system 1A of a second embodiment will be described with reference to Fig. 8, focusing mainly on the differences from the first embodiment. In the component mounting system 1A of the second embodiment, an operator attempts to make effective use of a multiple board K on which the printing condition of the paste solder is not good. To achieve this, a rework control unit 38 is additionally provided on the first component mounting line 3. The rework control unit 38 may be provided on the second component mounting line 5, or on both lines.

In the second embodiment, if the solder inspection machine 32 judges that the printing condition of any one of the six small boards (KS1 to KS6) of the multiple board K is not good and that the board has failed, it sets the skip information "1" to the corresponding instruction information (C1 to C6). At the same time, the solder inspection machine 32 notifies the operator of the failure and requests a reinspection. The operator reinspects the multiple board K in the solder inspection machine 32 by visual inspection or the like. If the reinspection is successful, the operator inputs a pass to the solder inspection machine 32. This causes the solder inspection machine 32 to cancel the skip information "1" and it is considered that there was no failure.

On the other hand, if the reinspection also fails, the operator removes the multi-panel board K from the solder inspection machine 32. The operator then operates the rework control unit 38. The rework control unit 38 resets and erases the top surface order information TN for the corresponding row of the first reference data DQ1 and the skip information "1" present in the instruction information (C1 to C6). This makes the multi-panel board K ready to be brought in again at any time. The operator then removes the solder paste from the multi-panel board K and brings it back into the solder printing machine 31. Thus, the multi-panel board K that was once determined to include a failing board is now considered to pass and can be used effectively.

6. Component mounting system 1B according to the third embodiment
Next, a component mounting system 1B according to a third embodiment will be described with reference to Fig. 9, focusing mainly on the differences from the first and second embodiments. In the component mounting system 1B according to the third embodiment, a repair station 39 is additionally provided on the first component mounting line 3. The repair station 39 may be provided on the second component mounting line 5, or on both lines.

The repair station 39 is disposed between the second board visual inspection machine 35 and the reflow machine 36. The repair station 39 is configured to be able to access the first reference data DQ1. The repair station 39 is where an operator works on multiple boards K that have been determined to include failures by the first board visual inspection machine 34 and the second board visual inspection machine 35. Multiple boards K that have been determined to pass by the first board visual inspection machine 34 and the second board visual inspection machine 35 pass through the repair station 39. On the other hand, multiple boards K that have been determined to include failures are temporarily stopped at the repair station 39. Furthermore, the occurrence of failures is notified to the operator.

The tasks performed by the operator at the repair station 39 include re-inspection, repair, and mounting. In re-inspection, the operator re-inspects the mounting state of the components by visual inspection or by using an image magnifier. In repair, a repair soldering iron or the like is used to improve the mounting state of the components. In mounting, the operator manually mounts the unmounted components that the component mounting machine 33 failed to mount.

If the judgment result can be corrected to pass by the work, the operator inputs that it is pass to the repair station 39. This causes the repair station 39 to cancel the skip information "1" set by the first board visual inspection machine 34 and the second board visual inspection machine 35, and it is treated as if there were no failures. Alternatively, the repair station 39 may transport the multiple board K for which work has been completed back to the second board visual inspection machine 35 for reinspection. In this way, the multiple board K that was once judged to include failures is changed to pass and can be used effectively.

7. Component mounting system 1C according to the fourth embodiment
Next, a component mounting system 1C of a fourth embodiment will be described with reference to Fig. 10, focusing mainly on the differences from the first to third embodiments. In the component mounting system 1C of the fourth embodiment, the configuration of the second component mounting line 7 is modified. The second component mounting line 7 is configured with six substrate-related operation machines lined up. That is, an adhesive applicator 71, an adhesive inspector 72, a component mounting machine 73, a first substrate visual inspector 74, a second substrate visual inspector 75, and a dryer 76 are lined up in the order shown.

The adhesive applicator 71 applies a paste-like conductive adhesive to a specified location on the board. The adhesive inspector 72 inspects the state of application of the conductive adhesive. The component mounting machine 73 mounts components onto the conductive adhesive. The first board visual inspector 74 and the second board visual inspector 75 share the task of inspecting the mounting state of multiple components. The dryer 76 blows out hot air to dry and solidify the conductive adhesive. The adhesive inspector 72 also has a unique information acquisition unit 77.

In the fourth embodiment, the target is a single-sided mounting type board, and first, the components are mounted by soldering on the first component mounting line 3, and then the components are mounted with a conductive adhesive on the second component mounting line 7. The second component mounting line 7 has a different component mounting method from the first component mounting line 3. Nevertheless, the method of using the second reference data DQ2 on the second component mounting line 7 is the same as the method of using the first reference data DQ1 on the first component mounting line 3. In the fourth embodiment, by using skip information "1", the same action and effect as the first embodiment is achieved.

8. Application and Modification of the Embodiment The mounting operation is not limited to the multi-panel board K, and may be a general board that does not require separation. In this case, one amount of instruction information is used for one board. Also, the first line-specific storage unit 4 and the second line-specific storage unit 6 may be omitted, and each of the substrate-related operation machines on the first component mounting line 3 and the second component mounting line (5, 7) may access the mounting operation data DP in the shared storage unit 2. Furthermore, management without using the top surface order information TN and the bottom surface order information BN is also possible. For example, as disclosed in Patent Document 1, the first line-specific storage unit 4 and the second line-specific storage unit 6 may be used to transfer instruction information (C1 to C6) between adjacent substrate-related operation machines.

In addition, in the fourth embodiment, a component insertion machine may be provided in place of the adhesive applicator 71, adhesive inspection machine 72, and component mounting machine 73 on the second component mounting line 7. The component insertion machine inserts and attaches components to connectors mounted on single-sided mounting type boards on the first component mounting line 3 without using solder paste or conductive adhesive. This configuration also produces the same effects and advantages as the first embodiment. The second, third, and fourth embodiments can be implemented in a composite combination. Various other applications and modifications of each embodiment are possible.
