By the way, as such a substrate production line, there is a configuration in which the number of lanes changes in the middle because a work device having a small number of lanes is arranged in the middle of the line. In such a line configuration, it is conceivable to change the lane for transporting the board once at the place where the number of lanes is small, and then return the board to the original lane at the place where the number of lanes returns. , The substrate production line of Patent Document 1 does not consider such a case. In the board production line, it is necessary to smoothly transport the board and work efficiently, so it is required to appropriately respond to such a change in the lane.

It is a main object of the present disclosure to make it possible to appropriately determine the lane for transporting a substrate in a line configuration in which the number of lanes changes in the middle.

The present disclosure has taken the following steps to achieve the above-mentioned main objectives.

The information setting unit for setting the lane designation information designated by associating one lane among the plurality of lanes with each board, and the work device on the upstream side to the work device on the downstream side. The gist is to include an information management unit that manages the lane designation information so that the lane designation information of the board is acquired by the work apparatus on the downstream side prior to the delivery of the board.

In the board production line of the present disclosure, one lane out of a plurality of lanes is associated with each board to set specified lane designation information, and prior to delivery of the board from the upstream work device to the downstream work device. Then, the lane designation information is managed so that the lane designation information of the board is acquired by the work equipment on the downstream side. As a result, the lane designation information can be sequentially acquired by each work device, so that the lane for transporting the board is used at a place where the number of multiple lanes in parallel changes in the middle and returns to the original number of lanes. Can be easily determined to the original lane. Therefore, it is possible to appropriately determine the lane for transporting the substrate in the line configuration in which the number of lanes changes in the middle.

The following is a description of the operation of the substrate production line 10 of the present embodiment configured in this way. 4 to 6 are explanatory views showing an example of delivery of the substrate S and the substrate information file FL. Each working device 20 changes the width of each conveyor according to the width of the substrate S when the substrate S is received, but the description thereof will be omitted because it does not make the gist of the present disclosure.

As shown in FIG. 4, the print control unit 21d of the printing device 21 first has a processing target located on the most upstream side of the lane (first lane L1 or second lane L2) of the substrate production line 10 via the reading device 12. The board information of the board S of the above is acquired (S100). Next, the print control unit 21d confirms that the substrate S is not on the conveyor corresponding to the lane in which the substrate S is input among the first conveyor 21a and the second conveyor 21b, and then the printing apparatus 21 The board S is carried into the inside (S110). Subsequently, the print control unit 21d controls the print unit 21c based on the print position of the production-related information corresponding to the board information to print the solder on the board S (S120). When printing is performed on the substrate S, the print control unit 21d includes the substrate information acquired in S100 and the lane designation information indicating whether the substrate S is conveyed in the first lane L1 or the second lane L2. The information file FL1 is created and stored in the first storage area 41 of the shared folder 40 (S130). When the board S is put into the lane (either the first lane L1 or the second lane L2) designated in advance for each board S by the information management device 30, the print control unit 21 is laned from the information management device 30. The information regarding the designation of the above may be acquired to generate the lane designation information, which may be included in the board information file FL. Then, the print control unit 21d transmits a carry-out signal indicating that the board S in the printed lane can be carried out to the print inspection device 22 on the downstream side (S140). As described above, the carry-out signal can notify which lane the board S is carried out.

Upon receiving the carry-out signal, the print inspection control unit 22d of the print inspection device 22 accesses the first storage area 41 of the shared folder 40, reads the board information file FL1, and deletes the board information file FL1 (S200). Depending on the status of the printing process of the printing apparatus 21, the board information file FL1 of the board S of the first lane L1 and the board information file FL1 of the board S of the second lane L2 are stored in the first storage area 41. May be. In that case, the print inspection control unit 22d shall read the board information file FL in which the lane notified by the carry-out signal and the lane (designated lane) designated by the lane designation information of the board information file FL1 match. Just do it. Further, the print inspection control unit 22d confirms that the substrate S is not on the conveyor corresponding to the designated lane in the print inspection device 22, that is, the designated lane is vacant (S210). , A carry-on signal indicating that the board S can be carried into the lane is transmitted to the printing device 21 on the upstream side (S220). If the lane is not open in S210, the print inspection control unit 22d waits for the substrate S to be carried out of the apparatus. Further, in S210 and S220, the lane designated by the lane designation information is used, but the lane may be notified by the carry-out enable signal. Further, as described above, the carry-in enable signal can notify which lane is the lane in which the board S is carried. The print control unit 21d of the printing apparatus 21 that has received the carry-in enable signal controls the conveyor corresponding to the lane notified by the carry-out signal of S140 to carry out the substrate S (S150). Further, the print inspection control unit 22d controls the conveyor corresponding to the lane notified by the carry-in enable signal of S220 to carry in the substrate S (S230). Then, the print inspection control unit 22d controls the print state measurement unit 22c to inspect the print state of the substrate S (S240). The print inspection control unit 22d determines the presence or absence of print misalignment by collating with the print position included in the production-related information corresponding to the board information, and acquires the print position misalignment amount for each print misalignment position. When the print inspection control unit 22d inspects the print state of the board S, the print inspection control unit 22d creates a board information file FL2 in which print result information such as a print position shift amount is added to the contents of the board information file FL1 and creates a second board information file FL2 of the shared folder 40. It is stored in the storage area 42 (S250). Therefore, the board information file FL2 includes the same lane designation information as the board information file FL1. Subsequently, the print inspection control unit 22d transmits a carry-out signal of the board S to the mounting device 23 on the downstream side (S260).

The mounting control unit 23d of the mounting device 23 that has received the unloadable signal accesses the second storage area 42 of the shared folder 40, reads the board information file FL2 corresponding to the lane notified by the unloadable signal, and stores the second storage area 42. The board information file FL2 is deleted from the area 42 (S300). Further, the mounting control unit 23d confirms that the lane specified by the lane designation information of the board information file FL2 is vacant (S310), and then sends a carry-in enable signal to the lane to the print inspection device 22 on the upstream side. Send (S320). In S310 and S320, the lane is designated by the lane designation information, but it may be the lane notified by the carry-out possible signal. Upon receiving the carry-in enable signal, the print inspection control unit 22d of the print inspection device 22 controls the conveyor corresponding to the lane notified by the carry-out signal of S260 to carry out the substrate S (S270). Further, the mounting control unit 23d controls the conveyor corresponding to the lane notified by the carry-in enable signal of S320 to carry in the substrate S (S330). Then, the mounting control unit 23d controls the mounting unit 23c to mount the component on the substrate S (S340). Since the mounting control unit 23d reads the board information file FL2 including the print position deviation amount, the component can be accurately mounted at the mounting position corrected based on the print position deviation amount. Further, since the printing device 21, the printing inspection device 22, and the mounting device 23 all include a transport conveyor corresponding to the first lane L1 and the second lane L2, the substrate S is transported to the lane designated by the lane designation information. be able to. Further, by information management using the shared folder 40 (storage area), the lane designation information is sequentially acquired by the work device 20 on the downstream side.

As shown in FIG. 5, when a component is mounted on the board S, the mounting control unit 23d adds mounting result information including information on the mounted component (part type, number of components, mounting position, etc.) to the board information file FL2. The board information file FL3 is created and stored in the third storage area 43 of the shared folder 40 (S350). Therefore, the board information file FL3 includes the same lane designation information as the board information file FL2. Subsequently, the mounting control unit 23d transmits a carry-out signal of the board S to the lane switching device 24 on the downstream side (S360).

Upon receiving the unloadable signal, the switching control unit 24b of the lane switching device 24 confirms that the board S is not on the shuttle conveyor 24a, that is, the shuttle conveyor 24a is vacant (S400), and then receives the unloadable signal. The shuttle conveyor 24a is moved to the notified lane (S410). Then, the switching control unit 24b transmits the carry-in enable signal of the board S to the mounting device 23 on the upstream side (S420). The mounting control unit 23d of the mounting device 23 that has received the carry-in enable signal controls the transport conveyor corresponding to the lane notified by the carry-out signal of S360 to carry out the board S (S370). Further, the switching control unit 24b controls the shuttle conveyor 24a to carry in the substrate S (S430). Subsequently, the switching control unit 24b transmits a carry-out signal of the board S to the mounting inspection device 25 on the downstream side (S440).

Upon receiving the unloadable signal, the mounting inspection control unit 25c of the mounting inspection device 25 accesses the third storage area 43 of the shared folder 40, reads the board information file FL3, and deletes the board information file FL3 from the third storage area 43. (S500). Further, the mounting inspection control unit 25c confirms that the first lane L1 is vacant (S510), and then transmits a carry-in enable signal to the first lane L1 to the upstream lane switching device 24 (S520). .. Since the mounting inspection device 25 constitutes only the first lane L1, even if the second lane L2 is specified in the lane designation information of the board information file FL3, the board S is specified in the first lane L1 regardless of the designation. Will be accepted. Upon receiving the carry-in enable signal, the switching control unit 24b moves the shuttle conveyor 24a to the first lane L1 (S450) and carries out the substrate S from the shuttle conveyor 24a (S460). Further, the mounting inspection control unit 25c controls the conveyor 25a to carry in the board S (S530), and inspects the mounting state of the board S by the mounting state measuring unit 25b while referring to the information of the board information file FL3 (S530). S540). As an inspection of the mounting state, the mounting state measuring unit 25b confirms the amount of mounting position deviation of the component, confirms the presence or absence of the unmounted component for which the component to be mounted could not be mounted, or when there is an unmounted component. Checks the component type and its original mounting position.

As shown in FIG. 6, when the mounting inspection control unit 25c inspects the mounting state of the board S, the mounting position deviation amount of the component and the unmounted component (component type and original mounting position) are included in the contents of the board information file FL4. The board information file FL4 including the mounting result information including the information related to the above) is created and stored in the fifth storage area 44 of the shared folder 40 (S550). Therefore, the board information file FL4 includes the same lane designation information as the board information file FL3. As a result, even if the mounting inspection device 25 constituting only the first lane L1 conveys the board S in the first lane L1 regardless of the lane designation information, the work device 20 on the downstream side is associated with the board S. The lane designation information can be reliably notified. Then, the mounting inspection control unit 25c transmits a carry-out signal of the board S to the lane switching device 26 on the downstream side (S560).

After confirming that the shuttle conveyor 26a is free (S600), the switching control unit 26b of the lane switching device 26 that has received the unloadable signal shuttles to the lane notified by the unloadable signal, that is, the first lane L1. The conveyor 26a is moved (S610). Then, the switching control unit 26b transmits the carry-in enable signal of the board S to the mounting inspection device 25 on the upstream side (S620). The mounting inspection control unit 25c of the mounting inspection device 25 that has received the carry-in enable signal controls the transfer conveyor 25a to carry out the substrate S (S570). Further, the switching control unit 26b controls the shuttle conveyor 26a to carry in the substrate S (S630). Next, the switching control unit 26b transmits a carry-out signal of the board S to the mounting device 27 on the downstream side (S640).

The mounting control unit 27d of the mounting device 27 that has received the unloadable signal accesses the fourth storage area 44 of the shared folder 40, reads the board information file FL4, and deletes the board information file FL4 from the fourth storage area 44 (. S700). Further, the mounting control unit 27d confirms that the lane specified by the lane designation information of the board information file FL4 is vacant (S710), and then sends a signal that the board S can be carried into the designated lane to the upstream lane. It is transmitted to the switching device 26 (S720). The switching control unit 26b of the lane switching device 26 that has received the carry-in enable signal moves the shuttle conveyor 26a to the lane notified by the carry-in possible signal (S650), and carries out the substrate S from the shuttle conveyor 26a (S660). Further, the mounting control unit 27d controls the conveyor corresponding to the carry-in enable signal of S720 to carry in the substrate S (S730). Then, the mounting control unit 27d controls the mounting unit 27c to mount the components on the substrate S (S740). In this way, even if the substrate S is transported in a lane different from the lane designated because the number of lanes is once reduced by the mounting inspection device 25, the board S is returned to the original lane by the lane switching device 26 and the mounting device 27. Can be returned. Further, since the mounting device 27 may cause the lane switching device 26 to switch the transfer of the board S to the lane designated by the lane designation information, the board S can be returned to the original lane by a simple process.

Here, the correspondence between the constituent elements of the substrate production line 10 of the present embodiment and the constituent elements of the substrate production line of the present disclosure will be described. The work device 20 corresponds to the work device, the print control unit 21d of the printing device 21 corresponds to the information setting unit, and the shared folder 40 for storing the board information file FL including the lane designation information so that each work device 20 can access is provided. The information management device 30 possessed corresponds to an information management unit.

In the board production line 10 of the present embodiment described above, one lane of the first lane L1 and the second lane L2 is associated with each board S and designated lane designation information is set, and the work device on the upstream side is set. Prior to the delivery of the board S from the 20 to the work device 20 on the downstream side, the shared folder 40 is used to manage so that the lane designation information of the board S is acquired by the work device 20 on the downstream side. As a result, the lane designation information can be sequentially acquired by each working device 20, so that the lane of the board S can be easily changed to the original lane at a place where the number of lanes decreases in the middle and returns to the original number of lanes. It becomes possible to decide.

Further, the mounting inspection device 25 that does not constitute the second lane L2 conveys the substrate S in the first lane L1 regardless of the lane designation information, and the other working devices 20 that configure the dual lane convey the substrate S according to the lane designation information. It is possible. Therefore, even if the number of lanes configured by each work device 20 is different, the substrate S can be appropriately conveyed.

Further, in the board production line 10, the board file information FL including the lane designation information is managed by using the shared folder 40 accessible to the first to fourth storage areas 41 to 44 corresponding to each work device 20. Then, each working device 20 acquires the board file information FL including the lane designation information from the corresponding first to fourth storage areas 41 to 44, controls the transfer of the board S, and performs the lane designation information. Delete the included board file information FL. Further, each work device 20 stores the board information file FL including the lane designation information of the board S in the storage area corresponding to the work device 20 on the downstream side when the predetermined work is executed on the board S. Therefore, each working device 20 can easily acquire the lane designation information of the board S and control the transfer of the board S at an appropriate timing according to the delivery of the board S.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be carried out in various embodiments as long as it belongs to the technical scope of the present invention.

For example, in the above-described embodiment, the working device 20 constituting the lane designated by the lane designation information always conveys the substrate S on the lane (conveyor conveyor), but the present invention is not limited to this. FIG. 7 is a flowchart showing an example of the mode switching process, and FIG. 8 is an explanatory diagram showing the transfer of the board S and the board information file FL of the modified example. It is assumed that the flowchart of FIG. 7 is executed by the mounting control unit 27d of the mounting device 27.

In the mode switching process of FIG. 7, the mounting control unit 27d determines whether or not a mode switching instruction has been received from the information management device 30 (S10), and if it determines that the mode switching instruction has been received, the mode switching process is entered into the designated priority mode. It is determined whether or not it is a switching instruction (S20). The mounting device 27 of the modified example has two modes, a designated priority mode in which the lane designated by the lane designation information is prioritized, and an efficiency priority mode in which the work (production) efficiency of the substrate S is prioritized over the designated lane. Either can be selectively set. Further, the information management device 30 determines which mode to use based on the board type of the board S to be produced, the type of parts to be mounted, and the like, and transmits an instruction to the mounting device 27. When the mounting control unit 27d determines that the designated priority mode is instructed in S20, the mounting control unit 27d switches from the efficiency priority mode to the designated priority mode (S30), and ends the mode switching process. Further, when the mounting control unit 27d determines that the efficiency priority mode is instructed in S20, the mounting control unit 27d switches from the designated priority mode to the efficiency priority mode (S40), and ends the mode switching process. In the designated priority mode, the same processing as that of the above-described embodiment is performed, and therefore the description thereof will be omitted.

In FIG. 8, the same process as in FIG. 6 is assigned the same step number. FIG. 8 shows a state in which the mounting control unit 27d is switched to the efficiency priority mode, and the processing of the mounting device 27 after S700 is mainly different from that of FIG. When the mounting control unit 27d of the mounting device 27 reads the board information file FL4 in S700 and deletes it, it confirms the availability of the first lane L1 and the second lane L2 (S710a), and shifts to the lane specified by the lane designation information. Regardless, a vacant lane is determined in order to prioritize production efficiency (S715). When none of the lanes is vacant in S710a and S720, the mounting control device 27d waits for either the first lane L1 or the second lane L2 to become vacant, and determines the vacant lane first. And. Then, the carryable signal of the board S to the determined lane is transmitted to the lane switching device 26 on the upstream side (S720a). The switching control unit 26b of the lane switching device 26 that has received the carry-in enable signal moves the shuttle conveyor 26a to the lane notified by the carry-in signal (S650a), and controls the shuttle conveyor 26a with S660 to carry out the board S. do. Further, the mounting control unit 27d controls the conveyor corresponding to the determined lane to carry in the substrate S (S730a).

Further, the number of lanes changes is not limited to one, and may be two or more. Further, the number of lanes is not limited to one that decreases by one lane, and may be one that decreases by two or more lanes. Further, the number of lanes once decreased is not limited to the one that returns to the maximum number of lanes, and the number of lanes may increase but does not return to the maximum number of lanes.

In the above-described embodiment, each working device 20 acquires lane designation information via the shared folder 40, but the present invention is not limited to this. The lane designation information transmitted via communication with the information management device 30 may be acquired before each working device 20 carries in the board S. Alternatively, the work device 20 on the upstream side and the work device 20 on the downstream side are configured to be communicable, and the lane designation information transmitted via the communication with the work device 20 on the upstream side is transmitted to the work device 20 on the downstream side. It may be something that is acquired by. Further, in the case where the information management device 30 transmits the lane designation information to each work device 20, the management control unit 32 of the information management device 30 may set and manage the lane designation information. In such a case, the information management device 30 corresponds to the information management device of the present disclosure.

In the above-described embodiment, the board information file FL includes board information, print result information, mounting result information, and the like in addition to the lane designation information, but the present invention is not limited to this, and any board may include lane designation information. Information, print result information, implementation result information, and the like may not be included, or information other than these may be included. However, in order to make effective use of the information in the work device 20 on the downstream side, it is preferable to include print result information and mounting result information.

In the above-described embodiment, the mounting inspection device 25 is exemplified as the working device 20 constituting only the first lane L1, but the present invention is not limited to this. For example, an inverting device that inverts the front and back of the substrate S, a buffer device having a buffer area for waiting for the substrate S, a reflow device that performs reflow processing of the substrate S, and the like may be used.

In the above-described embodiment, the lane switching devices 24 and 26 switch the lanes of the shuttle conveyors 24a and 26a based on the carry-out signal and the carry-on signal from the work device 20 on the upstream side or the downstream side to transport the substrate S. However, it is not limited to this. For example, the switching control units 24b and 26b of the lane switching devices 24 and 26 may switch lanes based on the lane designation information acquired by accessing the shared folder 40. In this case, a storage area corresponding to the lane switching devices 24 and 26 may be provided, and the lane switching devices 24 and 26 access the storage area of the work device 20 adjacent to the upstream side to provide lane designation information. May be obtained. Alternatively, the lane switching devices 24 and 26 are not limited to those provided with the switching control units 24b and 26b, and the lane switching and the transfer of the substrate S are controlled by the control unit of the working device 20 adjacent to the upstream side or the downstream side. And so on.

In the substrate production line of the present disclosure, when the working apparatus includes the lane designated by the lane designation information, the substrate is conveyed and controlled in the lane, and the work apparatus is designated by the lane designation information. When the lane is not provided, the transfer control of the substrate may be performed in any of the other lanes regardless of the designation of the lane. By doing so, even if the number of lanes configured by each work device is different, the transfer control of the substrate can be appropriately performed.

In the board production line of the present disclosure, the information management unit uses a shared folder in which the storage area is divided into a plurality of areas according to the number of the work devices and the work devices can access the corresponding storage areas. The work device manages the lane designation information, reads the lane designation information from the storage area corresponding to the own device, controls the transfer of the board, deletes the lane designation information, and deletes the lane designation information on the board. When the work is executed, the lane designation information of the board may be stored in the storage area corresponding to the work device on the downstream side. By doing so, each working apparatus can easily acquire the lane designation information of the board and control the transfer of the board at an appropriate timing according to the delivery of the board.

In the board production line of the present disclosure, as a mode related to the transfer control of the board, either a designated priority mode in which the lane specified in the lane designation information is prioritized or an efficiency priority mode in which the efficiency of the predetermined work is prioritized is selected. A mode setting means for setting is provided, and when the working apparatus includes the lane designated by the lane designation information, when the designated priority mode is set, the transfer control of the board is performed in the lane. When the efficiency priority mode is set, the transfer control of the substrate may be performed in an empty lane regardless of the designation of the lane. By doing so, it is possible to control the transfer by giving priority to either the lane designation or the work efficiency, so that the lane for transporting the board can be more appropriately determined even when the lane designation information is associated with the board.
