Description

This specification discloses a job processing method and a component mounting system.

Conventionally, a component mounting system including a component mounting machine in which a cassette type component supply unit for supplying components is replaceably mounted and a unit replacement device for automatically replacing the component supply unit has been proposed (for example, Patent Document). 1). In this system, the mounting process is started in a state where some of the plurality of component supply units required for the mounting process are set in the component mounting machine and the rest are not set in the component mounting machine. Then, every time a component supply unit whose supply of components has been completed occurs during the mounting process of one board, the component supply unit is automatically replaced with the remaining one component supply unit by the unit exchange device to perform the mounting process. conduct.

WO2017 / 085782A1

However, in the above-mentioned component mounting system, the component supply unit is automatically replaced every time a component supply unit whose supply of components is finished is generated. Therefore, the unit replacement device moves to the replacement position and automatically replaces the component supply unit each time. There is a need to do. For this reason, for example, when a component supply unit for which component supply has been completed occurs in each of a plurality of component mounting machines, the moving distance and the number of movements of the unit replacement device increase, causing a moving loss and automatic replacement. It will take time. In that case, waiting for replacement of the parts supply unit is likely to occur, which leads to a decrease in the production efficiency of the entire system.

The main purpose of the present disclosure is to suppress a decrease in production efficiency by automatically replacing parts supply units more efficiently.

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

In the job processing method of the present disclosure, a component mounting machine that collects components from a plurality of component supply units and mounts them on a board based on the job is exchanged with the component supply unit arranged in the component mounting machine. This is a job processing method in a component mounting system including a unit replacement device, wherein (a) the component supply unit that exceeds the maximum number of collectionable areas in which components can be collected from the component supply unit is used. In a job, a step of assigning the component supply unit to at least three groups, and (b) initial placement of the component supply unit of at least two of the three groups in the collectable area, and at least one. The step of initially arranging the component supply unit of the group in the non-collectable area where parts cannot be collected, and (c) the component supply unit used in the mounting process are sequentially switched in the group unit and in the collectable area. The step of setting the mounting order in the job so that the use is started from the initially placed group, and (d) the end of the mounting process using the component supply unit of the predetermined group placed in the collectable area. If it is determined, it is arranged in the component supply unit of the predetermined group and the non-collectable area while the mounting process is performed using the component supply unit of another group arranged in the collectable area. It is intended to include a step of controlling the unit replacement device so as to replace the component supply unit of one group in a group unit.

In the job processing method of the present disclosure, in a job in which parts supply units exceeding the maximum number of parts supply units that can be collected are used, at least two of the three groups to which parts supply units are assigned are initially placed in the collectable area. At the same time, at least one group is initially placed in the non-collectable area. When it is determined that the mounting process using the component supply unit of the predetermined group arranged in the collectable area is completed, the mounting process is performed while the component supply unit of another group is used. The parts supply unit of the group and the parts supply unit of one group arranged in the non-collectible area are replaced in group units. As a result, the mounting process can be performed while replacing the component supply units in a group unit, so that the component supply units can be efficiently and automatically replaced. Therefore, it is possible to suppress a decrease in production efficiency in a job in which a component supply unit that exceeds the maximum number of collectionable areas is used.

The management device 80 receives information on the mounting status of the component mounting machine 20 and information on the attached / detached feeder 30 from the mounting control device 28, and receives information on the driving status of the loader 50 from the loader control device 59. When the management device 80 receives information about the feeder 30 attached to the feeder base 40 of the component mounting machine 20 and the feeder 30 removed from the feeder table 40 from the mounting control device 28, the management device 80 updates the feeder list of the component mounting machine 20. do. Further, the management device 80 outputs a drive signal to the board transfer device 62 of the feeder storage 60 to transfer the board S to the board transfer device 62. Further, the management device 80 is communicably connected to the feeder control device 39 of the feeder 30 attached to the feeder stand of the feeder storage 60 via the connectors 35 and 45, and provides information on the feeder 30 attached to and detached from the feeder stand. Upon acquisition, the feeder list of the feeder storage 60 is updated.

The operation when processing the job in the component mounting system 10 configured in this way will be described. FIG. 6 is a flowchart showing an example of a job processing routine. This routine is executed by the CPU 80a of the management device 80. In this routine, the CPU 80a compares the number of feeders 30 used in the component mounting machine 20 in this job with the maximum number of arrangements of the supply area 20A (for example, value 40) (S100), and the number of feeders 30 is the maximum. It is determined whether or not the number is equal to or less than the number of arrangements (S105). When the CPU 80a determines that the number of feeders 30 is equal to or less than the maximum number of arrangements, it executes normal job processing (S110), and when it determines that the number of feeders 30 exceeds the maximum number of arrangements, it executes job processing when the number of feeders is exceeded. (S115), the job processing routine is terminated. The CPU 80a determines S105 for each component mounting machine 20, and determines whether to perform S110 or S115 for each component mounting machine 20. The normal job process is a well-known content that causes the implementation process to be performed based on the job, and the description thereof is omitted because it does not make the gist of the present disclosure. The job processing when the number of feeders is exceeded will be described below.

In the job processing when the number of feeders in FIG. 7 is exceeded, the CPU 80a first divides the feeder 30 used in the component mounting machine 20 into two groups (for example, 20) by dividing the maximum number of arrangements of the supply area 20A into two groups G1. Allocate to G3 (S200). For convenience of explanation, the job processing when the number of feeders in one component mounting machine 20 is exceeded will be described, and the number of feeders 30 used in the component mounting machine 20 will be 60. Therefore, 20 feeders are assigned to each of the groups G1 to G3. Subsequently, the CPU 80a outputs an instruction to the loader control device 59 so that the feeders 30 of the groups G1 and G2 are initially arranged in the supply area 20A and the feeders 30 of the group G3 are initially arranged in the stock area 20B (S205). The loader control device 59 controls the loader 50 based on the instruction to perform initial arrangement of the feeders 30 of the groups G1 to G3. Then, the CPU 80a sets the mounting order of the components in the order of the groups G1, G2, and G3, starting from the group G1 initially arranged in the supply area 20A (S210). The CPU 80a can optimize the mounting order within the group Gn (n is any of the values 1, 2, and 3). For example, the CPU 80a sets the optimum mounting order within the group Gn in consideration of the collecting position when the suction nozzle collects parts, the moving distance from the collecting position to the mounting position, the number of mounted parts for each part type, and the like. .. Further, the CPU 80a associates the actual slot number with the slot number of the feeder list for the feeder 30 initially arranged in the supply area 20A (S215), and the slot number of the feeder list for the feeder 30 initially arranged in the stock area 20B. The virtual slot number is associated with (S220).

FIG. 8 is an explanatory diagram showing an example of a feeder list, and FIG. 9 is an explanatory diagram showing an example of mounting order information. The feeder list of FIG. 8 includes a slot number (position information) in which each feeder 30 is arranged, a feeder ID (identification information), a component type, correspondence information (CD **), and the like. The actual slot number is the number of the slot 42 from "01" to "40" that actually exists in the feeder stand 40. Further, the virtual slot number is a virtual number that does not actually exist in the feeder stand 40, and is, for example, a number from "41" to "60" following the actual slot number. The correspondence information is information that associates the feeder list with the mounting order information, and is used to specify the slot number of the feeder 30 that supplies parts from the mounting order. In the initial arrangement state, the corresponding information number matches the slot number. It should be noted that each mounting control device 28 may also create a feeder list for its own machine in the same manner. The mounting order information in FIG. 9 includes the mounting order of components, component types, mounting positions and arrangement angles on the substrate S, correspondence information, group information, and the like. For example, in FIG. 9, the corresponding information of the component type A1 * whose mounting order is “001” is “CD01”, and in FIG. 8, the corresponding information “CD01” is associated with the slot number “01”. It can be seen that the parts of the product type A1 * are supplied from the feeder 30 of the slot number “01”. Further, in FIG. 9, the mounting order is determined in the order of the groups G1, G2, and G3, and the optimum mounting order is determined in each group regardless of the arrangement order of the feeders 30.

The CPU 80a sends a job including the mounting order information created in this way to the component mounting machine 20 to start the mounting process (S225). The feeder list may be included in the job and transmitted to the component mounting machine 20. Then, the CPU 80a waits for receiving the mounting end notification from the component mounting machine 20 (S230). The details of this implementation end notification will be described later. When the CPU 80a determines that the mounting end notification has been received, it determines whether or not the mounting process of all the boards S has been completed (S235), and when it determines that it has not been completed, the CPU 80a is a group unit in which the feeder 30 is replaced in group units. The feeder replacement process of (S240) is executed, and the process returns to S230. Before explaining the details of this feeder replacement process, the mounting process of the component mounting machine 20 will be described.

FIG. 10 is a flowchart showing an example of the mounting processing routine. This routine is executed by the mounting control unit 28. In this routine, the mounting control device 28 first acquires the job mounting order information and the feeder list (S300), and controls the board transfer device 21 to carry in the board S (S305). Next, the mounting control device 28 sets the group Gn to which the parts are supplied to the group Gn1 (S310), and executes the mounting process of the group Gn (here, the group G1) shown in FIG. 11 (S315).

In the mounting process of the group Gn in FIG. 11, the mounting control device 28 selects the component to be mounted in the group Gn based on the mounting order (S400), and refers to the feeder list from the correspondence information of the selected component to refer to the feeder 30. The slot number is specified (S405). For example, in the case of a component in the mounting order "001" of the group G1, the slot number "01" is specified by referring to the feeder list from the corresponding information "CD1" as described above. Next, the mounting control device 28 controls the head 22 so that the parts supplied from the feeder 30 having the specified slot number are sucked by the suction nozzle (S410), and the head 22 is moved onto the parts camera 25 to move the parts. The suction component is imaged by the camera 25 (S415). Subsequently, the mounting control device 28 performs image processing of the captured image (S420), and determines whether or not an error such as failure to mount the component due to improper suction of the component has occurred (S425). If the mounting control device 28 determines that no error has occurred, the component is mounted on the board S based on the job mounting position and placement angle (S430), and if it is determined that an error has occurred, the mounting control device 28 performs recovery target setting processing. Do (S435). In the recovery target setting process, processing such as discarding a component whose component has not been properly adsorbed or setting it as a target for recovery implementation process is performed. Then, the mounting control device 28 determines whether or not the mounting process of the parts of the group Gn is completed (S440), and if it is determined that the process is not completed, the mounting control device 28 returns to S400 and performs the process, and if it is determined that the process is completed, the group Gn Ends the implementation process of.

When the mounting process of the group Gn is executed in this way, the mounting control device 28 determines whether or not there is a recovery target component (S320), and when it is determined that there is a recovery target component, the mounting control device 28 newly adsorbs the target component and the substrate. The recovery implementation process to be implemented in S is performed (S325). When the recovery mounting process is performed, the mounting control device 28 determines whether or not the recovery mounting process has been completed for all the target components (S330), and if it is determined that the recovery mounting process has not been completed, returns to S325 and performs the recovery processing. When the mounting control device 28 determines that there is no recovery target component in S320 or determines that the recovery mounting process is completed in S330, it is assumed that all the group Gn mounting processes including the recovery mounting process are completed. , The implementation end notification including the designation of the group Gn is transmitted to the management device 80 (S335). The CPU 80a of the management device 80 that has received this notification determines that the mounting end notification has been received in S230 of FIG.

Then, the mounting control device 28 determines whether the current group Gn is the group G1 (S340) or the group G2 (S345). When the mounting control device 28 determines that it is in the group G1, the group Gn is set to the group Gn2 (S350), returns to S315, and the mounting process of the group Gn (here, the group G2) is executed. Further, when the mounting control device 28 determines that the group G2 is in the group G2, the mounting control device 28 sets the group Gn to the group Gn3 (S355), returns to S315, and executes the mounting process of the group Gn (here, the group G3). In this way, the mounting control device 28 executes the mounting process in group units, and sends a mounting completion notification to the management device 80 each time the mounting process in group units is completed. Further, when the mounting control device 28 determines that the current group Gn is not the groups G1 and G2 but the group G3, the mounting control device 28 controls the board transfer device 21 to control the board S, assuming that the mounting process of the current board S is completed. Carry out (S360). Then, the mounting control device 28 determines whether or not the mounting process of all the boards S has been completed (S365), and if it is determined that the process has not been completed, the mounting control device 28 returns to S305 to perform the process, and if it is determined that the process has been completed, the mounting process is performed. End the routine.

Next, the feeder replacement process for each group executed in S240 of FIG. 7 will be described. FIG. 12 is a flowchart showing an example of the feeder replacement process for each group, and FIG. 13 is an explanatory diagram showing how the feeder 30 is replaced for each group. Note that FIG. 13 shows a case where any group Gn is supplying parts (used in the mounting process). In the process of FIG. 12, the CPU 80a of the management device 80 determines whether the group Gn of the implementation end notification received in S235 is the group G1 (S500) or the group G2 (S505). When the CPU 80a determines that the group Gn of the mounting end notification is the group G1, it outputs an instruction to the loader control device 59 to replace the feeders 30 of the group G1 and the group G3 (S510), and ends the feeder replacement process. .. As a result, the group G1 for which the mounting process has been completed and the feeders 30 of the group G3 arranged in the stock area 20B are exchanged during the mounting process using the group G2 (see FIG. 13A). Further, when the CPU 80a determines that the group Gn of the mounting end notification is the group G2, the CPU 80a outputs an instruction to the loader control device 59 to replace the feeders 30 of the group G2 and the group G1 (S515), and performs the feeder replacement process. finish. As a result, the group G2 for which the mounting process has been completed and the feeders 30 of the group G1 arranged in the stock area 20B are exchanged during the mounting process using the group G3 (see FIG. 13B). Further, when the CPU 80a determines that the group Gn of the mounting end notification is not the group G1 or G2, the CPU 80a outputs an instruction to the loader control device 59 to replace the feeder 30 between the group G3 and the group G2 because it is the group G3. (S520), the feeder replacement process is completed. As a result, during the mounting process using the group G1 for the next board S after the mounting process using the group G3 is completed, the group G3 for which the mounting process is completed and the group G2 arranged in the stock area 20B are arranged. Each feeder 30 is replaced (see FIG. 13C). As described above, in the present embodiment, the feeder 30 not used in the mounting process is sequentially replaced in the group unit while the mounting process is performed in the group unit.

Along with such replacement of the feeder 30, the feeder list is also updated. FIG. 14 is an explanatory diagram showing an example of the feeder list update process. This process is executed by the mounting control device 28, but may be executed by the management device 80. In the feeder list update process, the mounting control device 28 first determines whether or not the feeder 30 has been removed (S600). When the mounting control device 28 determines that the feeder 30 has been removed, the mounting control device 28 temporarily stores the component type, feeder ID, and corresponding information corresponding to the removed slot number in a predetermined area of RAM (not shown) and deletes the feeder 30 from the feeder list. (S605). If the mounting control device 28 determines that the feeder 30 has not been removed, S605 is skipped.

Next, the mounting control device 28 determines whether or not the feeder 30 is attached (S610), and if it is determined that the feeder 30 is attached, the component type and feeder of the attached feeder 30 via the connections of the connectors 35 and 45. Acquire an ID (S615). Subsequently, the mounting control device 28 acquires the corresponding information that matches the feeder ID acquired in S615 from the information temporarily stored in the predetermined area of the RAM (S620), and the attachment destination of the feeder 30 this time is the supply area. It is determined whether or not it is 20A (S625). When the mounting control device 28 determines that the mounting destination is the supply area 20A, the mounting control device 28 registers the component type, ID, and correspondence information in the feeder list in association with the actual slot number of the mounted supply area 20A (S630). Return to S600. Therefore, when the feeder 30 removed from the stock area 20B is attached to the supply area 20A, the correspondence from the virtual slot number to the actual slot number is changed. On the other hand, when the mounting control device 28 determines that the mounting destination is the stock area 20B, the mounting control device 28 registers the component type, ID, and correspondence information in the feeder list in association with the virtual slot number instead of the slot number of the mounted stock area 20B. Then (S635), it returns to S600. Therefore, when the feeder 30 removed from the supply area 20A is attached to the stock area 20B, the correspondence is changed from the existing slot number to the virtual slot number.

FIG. 15 is an explanatory diagram showing an example of the updated feeder list. FIG. 15 shows a feeder list when the replacement shown in FIG. 13A is performed, and each feeder 30 in the group G1 is associated with a virtual slot. In the feeder list of FIGS. 8 and 15, even if the slot number of the feeder 30 changes, the corresponding information associated with the component type does not change. Therefore, the mounting control device 28 can appropriately specify the slot number of the feeder 30 from the mounting order by using the correspondence information regardless of how the feeder 30 is replaced.

Here, the correspondence between the components of the present embodiment and the components of the present disclosure will be clarified. The feeder 30 of this embodiment corresponds to a component supply unit, the component mounting machine 20 corresponds to a component mounting machine, the loader 50 corresponds to a unit replacement device, the supply area 20A corresponds to a collectable area, and the stock area 20B. Corresponds to the non-collectable area, and the component mounting system 10 corresponds to the component mounting system. S200 of the job process when the number of feeders in FIG. 7 is exceeded corresponds to step (a), S205 of the same process corresponds to step (b), and S210 of the same process corresponds to step (c). S240 corresponds to step (d). S215 and S220 of the same process correspond to step (e), and S630 and S635 of the feeder list update process of FIG. 14 correspond to step (f). S325 of the mounting processing routine of FIG. 10 corresponds to step (g). Further, the management device 80 that executes S200 in FIG. 7 corresponds to the allocation unit, and the management device 80 and the loader control device 59 that execute S205 of the same process correspond to the initial placement control unit, and execute S210 of the same process. The management device 80 corresponds to the mounting order setting unit, and the management device 80 and the loader control device 59 that execute S240 of the same process correspond to the replacement control unit.

Therefore, for a job in which the feeder 30 that exceeds the maximum number of arrangements of the supply area 20A is used, the mounting process can be performed while replacing the feeders 30 in a group unit, so that the feeders 30 can be efficiently and automatically replaced. It is possible to suppress a decrease in production efficiency. Therefore, it is possible to appropriately cope with a job using the feeder 30 exceeding the maximum number of arrangements without performing equipment expansion such as increasing the number of slots of the feeder stand 40.

Further, the actual slot number is set for the feeder 30 arranged in the supply area 20A, and the virtual slot number is set for the feeder 30 arranged in the stock area 20B. Therefore, even in a system in which the slot number of the feeder 30 is required to be set, it is possible to appropriately deal with it by a simple process. In addition, since the end of the group-based implementation process including the recovery implementation process is determined, it is not necessary to replace the feeder 30 again in order to perform the recovery implementation process, and it is possible to suppress a decrease in production efficiency. can. Further, since the feeders 30 obtained by dividing the maximum number of supply areas 20A into two are allocated to one group Gn, the number of feeders 30 allocated to each group Gn is increased as much as possible, and the effect of replacing the feeders 30 in group units is obtained. Can be made larger.
