Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply unit provided with a component supply unit having a large number of feeders for component supply, and an electronic component is sucked from the component supply unit by a component suction head to print a printed circuit board. The present invention relates to a setup timing management method and apparatus for managing a feeder replacement timing in accordance with a change in a mounting program in a mounting machine mounted on the device.

[0002]

2. Description of the Related Art Conventionally, an electronic component such as an IC is sucked from a component supply unit by a head having a suction nozzle, and is transferred onto a printed circuit board installed in a component mounting unit. Mounting machines designed to be mounted are generally known. In this mounting machine, a head unit having one or a plurality of heads is usually movable in the X-axis direction and the Y-axis direction. Also, in the parts supply section,
A component supply unit provided with a large number of feeders so as to be able to supply various components is provided, for example, a component supply unit provided with a large number of tape feeders arranged in parallel.

[0003] The component supply unit is usually mounted on a movable lump exchange carriage, and the lump supply carriage is fixed to a mounting machine main body so that the component supply unit is set in a state capable of supplying components. When the collective exchange trolley is separated from the mounting machine main body, the component supply unit can replace the entire trolley.

In a mounting machine, a required number of components are mounted in accordance with a mounting program according to a mounting target board. Various mounting programs are set in advance corresponding to various printed circuit boards, and mounting is performed by the mounting program. The types of components to be provided for the components and the proper arrangement in the component supply unit change. For this reason, a plurality of types of component supply units having different types and arrangements of feeders are prepared and mounted on the collective exchange cart in advance, while various programs to be produced, their order, the number of productions, and the like are determined. During the production according to the production plan, the parts supply unit is replaced as needed when the mounting program is changed (change of the board to be mounted). A setup change has been made in which some feeders in the supply unit are individually replaced.

[0005]

Among the above setup changes, the batch replacement of the component supply units can be easily performed by using the batch replacement cart, and the required time can be sufficiently shortened. The replacement of each feeder requires checking work and the like, and often requires replacement of a plurality of feeders, which is troublesome and takes a long time.

Therefore, if the feeder replacement is performed in advance for the part supply unit of the collective exchange cart that is not currently used in the mounting line, the feeder can be replaced offline.
Next, when the component supply unit of the collective exchange cart is used, the mounter need only be stopped for a minimum period of time only by the collective exchange operation using the cart, and the operating efficiency of the mounter can be improved. However, for example, if the component supply unit of the lump exchange trolley currently used in the mounting line is still used in the next mounting program, but the feeder in that component supply unit needs to be replaced, Such off-line pre-setup (called external setup) cannot be performed, but the mounting machine must be stopped and individual feeders replaced within the mounting line (called internal setup). However, according to the inner setup, the stopping time of the mounting machine is longer than that of the outer setup, and the operation efficiency of the mounting machine is deteriorated.

[0007] As described above, there are cases where the external setup can be performed and cases where the internal setup must be performed, and it is desired to increase the operating efficiency of the mounting machine by performing the external setup as much as possible. Inspects the production plan and sets up outside.
It is very troublesome to determine which of the inner setups should be performed and at what time. Also, as described above, when the outer setup cannot be performed and the inner setup must be performed,
If the worker is notified when the time for internal setup is near (just before the end of production), the internal setup for the next production can be prepared and the decrease in operating efficiency can be reduced. Conventionally, such a thing has not been performed.

In view of such circumstances, the present invention makes it possible to appropriately determine whether feeder replacement is to be performed externally or internally according to a production plan, and appropriately issue an instruction for replacing the feeder in accordance with the determination. Accordingly, it is an object of the present invention to provide a setup timing management method and apparatus capable of shortening the time for stopping the mounting machine for replacing the feeder as much as possible and improving the operation efficiency of the mounting machine.

Data preparation means for judging whether the internal setup is to be performed for a component supply unit, and generating data indicating any of external setup, internal setup, and no need for replacement; and data created by the data creation means. Timing setting means for setting a time for instructing that feeder replacement or preparation should be performed based on data, and a signal for instructing that feeder replacement or preparation should be performed at a time set by the timing setting means And output means for outputting to the display means.

[0012] In this apparatus, the timing setting means, for the component supply unit for which the external setup is determined, is performed before the start of the program using the component supply unit and the feeder replacement by the external setup is performed. The time for instructing the feeder replacement may be set within a period in which is possible (claim 5).

The output means may stop outputting the signal for instructing the feeder replacement when the external setup is completed and a notification to that effect is received (claim 6).

In addition, the timing setting means sets the time for instructing that preparation for feeder replacement should be performed for a component supply unit determined to be set in the internal process before the time when the internal setup can be started. A predetermined time close to this time may be set (claim 7).

Further, the timing setting means and the output means change the feeder exchange of the component supply unit to the internal setup when the component supply unit to be subjected to the external setup is not externally set up by a predetermined time. (Claim 8).

According to the method and the apparatus, the necessity and necessity of exchange of the feeder are distinguished for each mounting program based on the list of the production plan, and when the exchange of the feeder is necessary, the external setup is further performed. And the case of internal setup are distinguished, and the time for instructing that feeder replacement or preparation should be performed is set accordingly, and the instruction is displayed at that time. Thus, it is possible to easily know the time when the operator should replace the feeder or prepare for it. By performing the feeder replacement operation in accordance with this instruction, the time for stopping the mounting machine for the feeder replacement is reduced as much as possible.

By exchanging the feeders of some units, it is possible to deal with program changes.

FIG. 4 shows the configuration of a control system including the control unit 30 and the like. In this figure, a control unit 30 provided in the mounting machine main body includes an X-axis servo motor 1
5, Y-axis servo motor 9, Z-axis servo motor 18 and R
The axis servomotor 19 and the position detecting means 22, 23, 24, 25 provided in each servomotor are connected. Further, a display means 26 such as a CRT and a notifying means 27 such as a buzzer are connected to the control unit 30, and the off-line personal computer 28 and the control unit 30 are connected so as to be communicable.

The control unit 30 includes a driver 31,
It includes a main operation unit 32, a memory 33, and an output unit. The driver 31 is provided with the position detecting means 22 to 22 during mounting.
The servo motors 9, 15, 24, and 25 are controlled according to a command from the main processing unit 32 while checking the positions of the X axis, the Y axis, the Z axis, and the R axis based on the signal from 25.

The main processing section 32 controls each servomotor via the driver 31 to perform a series of component mounting operations such as picking up a component from a component supply portion and mounting the component on a printed circuit board. In addition, it includes a list creation unit 35, a data creation unit 36, and a timing setting unit 37 for managing setup timing.

The list creating means 35 is based on information necessary for creating a production plan input from an input means (not shown).
A list of production plans as shown in FIG. 5 is created. The list of production plans includes production planning mounting programs (AAA to GG) corresponding to various printed circuit boards to be produced.
G) and the number of sheets to be produced are arranged in accordance with the planned production order.

The data creating means 36 determines a component supply unit to be set in the component supply section for each mounting program based on the list, checks whether or not the feeder needs to be replaced, and checks the feeder. When the exchange is necessary, it is determined whether the exchange is the external setup or the internal setup, and data indicating whether the external setup, the internal setup, or the exchange is unnecessary is created. Specifically, FIG. Create the data as shown. That is, the production plan number (No. 1 to No. 7) indicating the production order, the production schedule mounting program (A
AA to GGG), the number of sheets to be produced, and the numbers (A1, A) of the batch exchange carts to be set in the front and rear component supply units.
2) The number of feeders (B1, B) that need to be replaced on the batch exchange cart set in each of the front and rear component supply units.
2) The data includes the production plan numbers (C1, C2) that can be set up for the collective exchange trolley set in each of the front and rear part supply units.

According to the example shown in FIG.
In any of No. 7, the batch exchange truck set in the front part supply unit is the first truck, and the number of feeders that need to be replaced on this truck is 0, that is, no setup change is required.
On the other hand, the batch exchange trolley set in the rear part supply unit is the No. 2 trolley in production plans No. 1 and No. 2,
No.4 bogie for No.4, No.2 bogie for production plan No.5, No.4 bogie for production plans No.6 and No.7, and later for No.3 to No.7 production plans There is a feeder that needs to be replaced on the batch exchange cart set in the component supply unit on the side.

In this case, the production plan No. 3
The necessary feeder exchange can be performed by an external setup from the time when the production according to the production plan No. 1 is performed. The feeder exchange required for the No. 3 bogie in the production plan No. 4 must be done internally because the No. 3 bogie is not exchanged between the No. 3 and No. 4 production plans. The feeder exchange necessary for the No. 2 bogie in the production plan No. 5 can be performed by external setup, but the No. 2 bogie is also used in the No. 1 and No. 2 production plans, so production according to the No. 3 production plan Can be set up from the time when the operation is performed. Production plan N for No. 4 bogie
The feeder exchange required in o.6 can be performed by external setup from the time when production is performed according to production plan No. 1. In addition, the feeder replacement required for the No. 4 bogie in production plan No. 7 is an internal setup.

The timing setting means 37 shown in FIG.
Sets the time for notifying that the feeder exchange should be performed based on the data created by the data creating means 36. In this case, an execution timing (a timing for instructing what to execute) is set for the external setup. This execution timing is set before the mounting program in which the batch exchange cart is used and within a period in which feeder exchange is possible (within a period after the production plan number shown in the column of C2 in FIG. 6). . Specifically, for example, [((the number of feeders requiring replacement) × the number of feeders that need to be exchanged) from the maximum advance time that can be set up, or the specified time before the scheduled use time of the truck, or from the scheduled use time of the truck.
(Replacement time per feeder) + (margin time)] may be set as the previous time.

For the internal setup, the timing of the preparation instruction (the timing of instructing what to prepare) is set. This timing is set to a time before the time when the internal setup can be started (the time when the production is to be ended according to the previous production plan) and close to this time. More specifically, the timing may be a time that is earlier than the time when the inner setup is required by a set time, or a time that is earlier than the time when the inner setup is needed by the production of the set number of substrates.

The output means 34 in FIG. 4 outputs a predetermined signal at the timing set by the timing setting means 37. For example, in the case of the external setup, a signal indicating that the feeder should be replaced by the external setup and the carriage to be replaced with the feeder is output to the display means 26 or the offline personal computer 28. In the case of the internal setup, a signal indicating that the feeder replacement due to the internal setup is approaching is output to the display means 26 or the offline personal computer 28, or a signal for operating the notification means 27 is output.

When there is a notification that the external setup has been completed for a specific bogie, the output means 34 stops outputting a signal indicating that feeder replacement should be performed for the bogie. Further, when the outer setup of the bogie to be set up outside has not been performed by the predetermined time, the feeder exchange of the component supply unit is changed to the inner setup, and the processing of the timing setting means 37 and the output means 34 is performed. .

When the production plan is changed, the list shown in FIG. 5 and the list shown in FIG. 6 are changed accordingly, and the timing set by the timing setting means 37 is recalculated. .

A specific example of the process for managing the setup timing will be described with reference to the flowcharts of FIGS.

FIG. 7 is a flowchart showing the preliminary processing. When the processing shown in this flowchart starts,
The component arrangement (feeder arrangement) of the component supply unit on each batch exchange cart is stored as backup data (step S1). Further, in order to sequentially examine the mounting programs of the production plan numbers after the current production, a value obtained by adding "1" to the production plan number is set as the production plan number n (step S2).

Next, the board data corresponding to the production plan number is read from the various board data stored in the memory 33 in advance (step S3), and the component arrangement of the collective exchange trolley to be used and the read board data are read. And the number of components (the number of feeders) that need to be replaced is determined based on the comparison result (step S4). This information is written into the data shown in FIG. 6 and stored in the memory (step S5). Then, assuming that the parts have been replaced, the component arrangement of the component supply unit on the trolley is changed (step S6), and the production plan number n is incremented (step S7). It is determined whether or not the number of the production plan has been reached (step S8), and if the determination is NO, the processing from step S3 is repeated.

If the determination in step S8 is YES, the value obtained by adding "1" to the plan number during production is the production plan number m.
(Step S9). Next, the production plan number m
It is determined whether or not there is a part (feeder) that needs to be replaced (step S10). If there is a part that needs to be replaced, if the trolley used in the production plan m is also used in the previous production plan (m-1), it is stored in the internal setup and memory (step S11). If not, the production plan in which the bogie used in the production plan m is used last is searched, and the next number of the production plan is stored in the memory as a production plan number that can be set up outside ( Step S12).

Further, after the production plan number m is incremented (step S13), it is determined whether or not the number m has reached the number of the final production plan (step S1).
4) If the determination is NO, the processing from step S10 is repeated, and if YES, the processing is terminated.

FIG. 8 is a flow chart showing the processing of the setup instruction during the operation of the mounting machine, which comprises three routines (a), (b) and (c). FIG. 7A shows a process for instructing outside setup. When the process starts, it is determined whether there is a plan that allows outside setup (step S21). If the determination is YES, execution of outside setup is performed. It is determined whether or not the timing has come (step S22).

When it is time to execute the external setup, it is determined whether or not there are a plurality of setup instructions (step S23). If there is a plurality of setup instructions, it is determined whether or not priority processing is to be performed (step S23). S24) When performing the priority processing, the setup with the highest priority is selected (step S2).
5).

Next, an instruction for external setup is output and displayed by the display means, or output to a personal computer (step S26).

FIG. 8B shows a process for instructing the internal setup. When the process is started, it is checked whether or not there is an internal setup in the next production plan (step S31). It is determined whether or not it is time to instruct the preparation for the internal setup (step S31), and the determination is YE.
If S, an instruction for internal setup preparation is output and displayed by the display means, or output to a personal computer (step S32).

FIG. 8C shows the external setup completion receiving process. When the process is started, it is determined whether or not a notification of the external setup completion has been received (step S41). The part arrangement of the part supply unit on the trolley is changed to the arrangement after the setup is completed (step S4).
2). Then, the next external setup instruction is searched.

According to this embodiment as described above, the number of feeders that need to be replaced is checked for each mounting program of each production plan by the pre-processing shown in the flowchart of FIG. When the feeder exchange is performed by the inner setup and the outer setup, it is distinguished. In the case of the outer setup, a time at which the feeder exchange can be started is obtained, and these data are stored in the memory 33. .

FIG. 8 (a) performed during operation.
By the processing of (b) and (c), the display is performed when the execution timing is reached for the external setup, and the display is performed when the preparation is to be performed for the internal setup.

The data shown in FIG. 6 relating to the rear part supply unit will be specifically described as an example.
As shown in, production plan No.3 (CPC)
Of No. 3 bogie for feeder exchange and production plan No.6
The feeder replacement of the No. 4 bogie targeted for the (Implementation program FFF) can be performed by external setup from the operation according to the production plan No. 1, and in this case, before these external setup is possible, The instruction to set up the outside of the third bogie to be used is given priority. In accordance with this instruction, the worker performs the outer setup of the No. 3 bogie during the operation period of the production plan No. 1 to No. 2 so that the operation of the production plan No. 2 and the operation of the production plan No. 3 are collectively performed. You only need to replace the exchange trolley, minimizing downtime.

When the external setup of the No. 3 truck is completed during the operation period of the production plan No. 1 or No. 2, the instruction of the external setup for this bogie is stopped, and the instruction of the external setup of the No. 4 bogie is issued. It is.

In addition, plan No. 5 (implementation program EEE)
Replacement of feeder for No. 2 bogie for production plan No. 3
It is possible to perform the external setup during the operation period of the production plan No. 3 to No. 4, and the instruction of the external setup of the No. 2 bogie is given priority, and the worker Production planning by externally setting up the bogie
It is only necessary to replace the luggage exchange trolley between the operation of No. 4 and the operation of production plan No. 5. In addition, the worker performs the outer setup of the No. 4 bogie according to the instructions before the end of the operation of the production plan No. 5, so that the operation of the production plan No. 5 and the production plan No. 6
It is only necessary to replace the luggage exchange trolley during the operation.

Replacement of feeder of No. 3 truck for production plan No. 4 (mounting program DDD) and production plan N
o.7 (Installation program FFF) The feeder replacement for the 4th trolley must be set up internally, but the instruction for internal setup preparation is given before the internal setup time, and the operator By preparing in accordance with the instruction, the time for stopping the mounting machine and replacing the feeder is reduced as much as possible.

In this way, the time for stopping the mounting machine for the feeder replacement while allowing the operator to easily know the time to perform the feeder replacement or the preparation by the instruction indicated by the display means or the like. Can be shortened to a necessary minimum.

In the above embodiment, the mounting machine is:
Although the component supply units 3A to 3D can be replaced collectively for the component supply unit, if the target is a mounting machine that cannot be replaced collectively, only the inner setup is instructed after determining whether feeder replacement is necessary or unnecessary. It is good to be done.

As shown in FIG. 10, when the feeder setup instruction is displayed, as shown in FIG. 10, in addition to the work items shown in FIG. 6, "D1: backup pin arrangement type" and "D2: The width of the substrate, "D3: nozzle type" or the like may be indicated. The details of these are as follows.

Backup Pin Arrangement Type (D1) When the arrangement of the backup pins for supporting the board from the back side is changed according to the type of the board, the internal setup instruction can be performed simultaneously with the feeder setup instruction. For example,
The backup pin arrangement type is indicated according to the type of the board, and when the mounting program is changed, if the backup pin arrangement type is the same, it is determined that there is no internal setup, and if the backup pin arrangement type is different, it is determined that the internal setup is present.
In the example of FIG. 10, since the backup pin arrangement type differs between the two mounting programs CCC and DDD and the other mounting programs, when the production plan changes from No. 2 to No. 3 and when No. 4 When the status changes from No. 5 to No. 5, an internal setup instruction is generated.

Substrate Width (D2) The width of the conveyor for transporting the substrate is changed according to the width of the substrate. In the case of a mounting machine which needs to change the conveyor width manually, when the width of the substrate changes, Accordingly, internal setup of the conveyor width adjustment is required. Therefore, the data of the board width is shown in correspondence with the production plan number, and it is determined from the data of the board width whether the internal setup is necessary. FIG.
In the example shown in Fig. 7, since the board width of the board of the mounting program GGG is different from that of the other boards, the production plans No. 6 to No. 7
, An internal setup instruction is issued.

Nozzle Type In a mounting machine that does not have an automatic suction nozzle changing device, the suction nozzle to be used must be mounted on the head in advance before the operation of the mounting machine. In such a case, the nozzle type is indicated in association with the production plan number, and it is determined from the data that the internal setup for nozzle replacement is necessary. In the example shown in FIG. 10, since the nozzle type is different between the FFF and GGG mounting programs and the other mounting programs, an internal setup instruction is generated when the production plan changes from No. 5 to No. 6. .

In addition to the above, for example, when a tray supply device is provided, the tray arrangement information of the program is compared with the type of the component tray arranged on each pallet of the tray supply device in the same manner as in the feeder. What is necessary is just to judge that internal setup is necessary. In a mounting machine equipped with two or more tray supply devices, external setup is also possible.

These setup factors are independent of each other.
Therefore, in the configuration shown in FIG.
If the feeder is replaced in the external setup before changing from o.2 to No.3, when changing from production plan No.2 to No.3, only the change of the backup pin arrangement needs to be done in the internal setup. This is more efficient than a case in which two operations of replacing the feeder and changing the arrangement of the backup pins are performed by the inner setup without performing the outer setup of the feeder.

[0063]

As described above, according to the present invention, a list of production plans is created in a mounting machine, and based on the list,
For each mounting program, it is necessary to determine whether or not the feeder needs to be replaced.If it is necessary to replace the feeder, determine whether to use the external setup or the internal setup, and replace the feeder based on the data indicating the determination result. Alternatively, since the time to instruct that preparation should be performed is set and displayed, the management of setup timing that can shorten the time to stop the operation of the mounting machine and increase the operation efficiency, This can be easily performed without imposing a great burden on the operator.

In particular, for a component supply unit that has been determined to be set up outside, the feeder can be replaced before the start of the program using the component supply unit and within a period in which the feeder can be replaced by the outside setup. In order to perform the replacement, a time for instructing the feeder replacement is set, and for the component supply unit determined to be the internal setup, preparation is performed at a predetermined time before the time at which the internal setup can be started. If you set a time to instruct the preparation of the internal setup,
The time for stopping the operation of the mounting machine for the setup can be shortened to a necessary minimum.
