Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply management system in printed circuit board unit production which has a plurality of production lines and can suitably produce printed circuit board units.

[0002]

2. Description of the Related Art When a printed circuit board unit is produced, a production line of the printed circuit board unit includes, for example, a printing machine, an adhesive supply, a chip mounter for mounting chip components, an SOP mounter for mounting large components, and a connector. After mounting a predetermined component on the printed board, the heating process by reflow completes the production of the printed board unit.

Further, in the case of producing a printed board unit, a production plan including a production model, a production number, a component part and its use number, a production delivery date, and the like is drafted by a production management department, and based on the instruction. The production department is in charge of production. The parts managed by the manufacturing management section described above are naturally managed in parts. Further, the manufacturing section is provided with a plurality of production lines, and the same parts are often used in each production line.

[0004] On the other hand, for chip components such as chip capacitors, for example, reel members stored in units of 5,000 are used as handling units. In the case of producing a printed board unit, when the chip mounter has run out of parts, it is necessary to replace the reel member and replenish the parts.

As a method of predicting the replacement time of the reel member, for example, a necessary reel member quantity is calculated with respect to the production plan quantity of the printed board unit, and the time until the reel member is replaced is determined by one reel. There is a method in which the number of parts held by a member is divided by the number of parts required to produce one printed board unit, and the result is multiplied by the tact time required to produce one printed board unit.

That is, the required number of reel members for the number of sheets to be produced is obtained by the following equation. The required number of reel members relative to the number of production units = (the number of production units × the number of parts required for one printed circuit board unit) / the number of components held by one reel member. Time until the replacement of the printed board = (the number of parts held by one reel member / the number of parts required for one printed board unit) × the tact time for producing one printed board unit.

[0007] The tact time is set in advance, and is a supply / discharge time of a printed board to a chip mounter constituting a production line, a time during which components are actually mounted, and a loss time of the chip mounter. And the addition of In the production progress, an error occurs in the production quantity between the actual production result of the printed board unit and the production plan of the printed board unit.

[0008] This means that an error occurs when estimating the replacement time of the reel member. In particular, when the same type of printed circuit board unit is continuously produced for one week, a large error occurs in estimating the replacement time of the reel member.

In order to solve the above problems, when estimating the time to replace a reel member, the parts inventory quantity is immediately updated based on the production results of the printed board unit, and the parts inventory quantity is grasped with high accuracy. By doing so, there is a method of predicting the replacement time of the reel member. The details will be described below.

FIG. 7 shows a configuration diagram of the prior art. In the figure, the stock management unit 81
, An arithmetic processing unit 82, a production result counting unit 83, a bar code reader 86, each mounter, and detection units 84a, 84b, 84c, 84d corresponding to each mounter.

When producing the same type of printed board unit, for example, as shown in FIG. 8 (a), the inventory management unit 81 supplies a part drawing number, an identification code of a reel member storing this part, and a reel member. Is registered with the number of parts in the reel held by the company.

The bar code reader 86 reads an identification code provided on a reel member. The display unit 87 displays necessary items in order to instruct a worker in a timely manner in the component shortage prediction system. Each mounter sets a reel member for storing chip components in a jig and mounts predetermined components on a printed board. The detectors 84a, 84b, 84c, 84d detect that mounting of components on the printed board by each mounter has been completed and that the printed board has passed through the mounter.

When producing the same type of printed circuit board unit, the production result counting section 83 is provided with each of the detection sections 84 described above.
Based on the information from a, 84b, 84c, and 84d, the production results of the printed board unit are counted each time one printed board unit is produced.

The arithmetic processing unit 82 calculates the consumption of parts each time one printed board unit is produced when the printed board unit is continuously produced, based on the input from the production result counting unit 83. This is to update the data of each reel member registered in the section 81. That is, mount information, which is a unit use unit required for producing one printed board unit shown in FIG. 8B, is set in advance, and based on a value obtained by multiplying this mount information by the number of actual production sheets. The number of parts in the reel held by the reel member of the data of the inventory management unit 81 is subtracted.

That is, the component consumption is obtained by the following equation.・ Parts consumption = Unit consumption of printed board unit production ×
8A. For example, when one printed circuit board unit is produced from the data of the inventory management unit shown in FIG. 8A, based on the mount information shown in FIG. As shown, the number of components in the reel is changed. Further, when one printed board unit is produced, the number of components in the reel is changed as shown in FIG. 8D based on the mount information shown in FIG. 8B.

Next, the processing procedure will be described with reference to FIG.

In step S51, the arithmetic processing unit 82
Informs the operator of the part exhaustion and replenishment time at each mounter where the work has started. For example, the display unit 87 displays which line is required to replenish which part and at what time.

In step S52, the operator prepares a part to be replenished in the jig before the occurrence of part exhaustion.

In step S53, the production result counting unit 83 counts the production result of the printed board unit by 1 based on a notification from each of the detection units 84a, 84b, 84c, 84d for detecting that the work is sequentially completed by each mounter. Count each sheet.

In step S54, the arithmetic processing unit 82
Calculates the component consumption based on the mount information every time one printed board unit is produced, and subtracts and updates the number of components in the reel registered in the inventory management unit 81.

In step S55, the arithmetic processing unit 82
Determines whether or not the component exhaustion replenishment time has been reached for each mounter. If the time has reached the component replenishment time, the process proceeds to step S56. If it is not time to replenish the parts, step S
Return to 51.

In step S56, the operator immediately replenishes components when the mounter stops due to running out of components. At this time, the bar code reader 86 reads the identification code of the reel member to be replaced when the component becomes empty and the identification code of the reel member to be supplied, and reads the component information of the replacement reel member and the component information of the refill reel member. It is transmitted to the arithmetic processing unit 82.

In step S57, the arithmetic processing unit 82
Stores the identification code of the reel member to be replenished in the inventory management unit 81
And the part information is registered in the inventory management unit 81. Further, it notifies the inventory management unit 81 of the identification code of the reel member to be replaced, and discards the component information registered in the inventory management unit 81.

In step S58, the arithmetic processing unit 82
According to the notification from the production result counting unit 83, the production result of the printed board unit is counted for each sheet, and it is confirmed whether there is a delay in the production plan.
Take appropriate action if there is a delay.

In step S59, it is determined whether the production is completed. If the production is not completed, the process returns to step S51.
If the production is completed, the processing is terminated.

[0026]

As described above, the prior art has the following problems.

1) When producing a printed board unit,
In the reel member mounted on the mounter, there is a component suction number in a process up to a process before the chip component is sucked from the reel member and mounted on the printed board unit. In addition, there is a number of mounted components in which chip components have been completely mounted on the printed board unit. Further, when a difference occurs between the number of picked-up parts and the number of mounted parts, there is an error number. That is, the number of errors indicates the number of components that could not be correctly mounted due to a recognition error, a suction error, or the like.

2) On the other hand, at the time of predicting the running out of parts, the consumption of the parts is calculated based on the value obtained by multiplying the mount information, which is the unit consumption of parts required to produce one printed board unit, by the actual production quantity. Each time one printed board unit is produced, the number of components in the reel held by the reel member of the inventory management unit is subtracted. That is, the calculation is performed based on the logical value based on the unit consumption of parts required to produce one printed board unit.

3) Therefore, even if the component consumption is calculated based on the logical value based on the component usage unit, if there is a difference between the number of picked up components and the number of mounted components, that is, if there is an error number, Parts consumption cannot be calculated accurately.

4) For this reason, when predicting the running out of parts of the reel member mounted on the mounter, if there is an error number, a large error occurs with the logical value.

[0031]

In order to solve the above problems, the present invention takes the following measures.

When producing a printed circuit board unit, the time at which a component will run out is predicted on the basis of the actual data of the component consumption.
That is, the component consumption amount actual data is the component suction number actually consumed by the mounter.

By taking the above-described means, the component cut-out time is predicted on the basis of the number of picked-up parts actually consumed by the mounter. Therefore, when there is a difference between the picked-up number of parts and the number of mounted parts, Even if there is, the component consumption is accurately calculated. For this reason, the prediction of the part exhaustion time becomes accurate.

[0034]

FIG. 3A shows the mounter information management unit 3.
5 shows a data configuration of the fifth embodiment. The data of the mounter information management section 35 includes reel member location data indicating a line, a mounter number, and a lane number, a part drawing number, a used number, and the like.

Detector 4 installed corresponding to each mounter
4a, 44b, 44c, and 44d detect the passage of the printed board unit, and the production result counting unit 43 obtains the component consumption result data of the mounter based on the component suction number every time one printed board unit is produced. I do.

The actual component consumption data is counted in total, and includes the number of components picked up by each single reel member mounted on the mounter, the number of mounted components, and the number of errors. The calculation of the component consumption is calculated based on the number of picked up components. In short, every time one printed board unit is produced, the actual component consumption data is acquired based on the number of picked up components.

That is, the component consumption is obtained by the following equation. -It can be obtained by the following equation: Component consumption per printed board unit production = total component consumption at the time of this production-total component consumption at the time of last production. The remaining number of components of the reel member is obtained by the following equation. The number of remaining parts of the reel member per production of one printed board unit = the number of remaining parts held by one reel member−the consumption of parts per production of one printed board unit. The number of errors per production of one printed board unit is obtained by the following equation. The number of errors per production of one printed circuit board unit = the amount of parts consumed per production of one printed circuit board unit—the number of parts used based on mounter information.

The production result counting section 43, which has obtained the actual data of the component consumption of each mounter every time one printed board unit is produced, outputs the actual data of the component consumption of each mounter every time one printed board unit is produced. The data is notified to the work plan simulation unit 42. The work plan simulation unit 42 obtains the result of the component consumption based on the number of picked-up components each time one printed board unit is produced, and rewrites and updates the data of the mounter result management unit 34. That is, each time one printed board unit is produced, the number of remaining parts of the reel member is updated.

FIG. 4 is an explanatory diagram of an embodiment of the present invention.

FIG. 4 is a diagram for explaining data rewriting of the mounter performance management unit 34. The remaining number of components (number of components in a reel) held by each reel member of the mounter performance management unit 34 in FIG. In ()), each time one printed circuit board unit is produced, its component consumption is calculated, and the number of remaining components is rewritten and updated. For example, FIG. 4A shows a case where the number of remaining parts of the reel member is updated when one printed board unit is produced. FIG. 4B shows a case where the remaining number of components of the reel member is updated when one more printed board unit is produced. If an error count occurs, the remaining component count of the reel member is updated to a count including the error count, and the difference between the component consumption count of the mounter and the component usage count based on the mounter information is updated as the error count.
That is, the number of remaining components is the true number of remaining components held by each reel member.

Next, the operating status of the production line and the notification of running out of parts will be described.

The time until the reel member is replaced is determined by the following equation. Time required to replace the reel member = (remaining number of components of one reel member / number of components required for one printed board unit) × tact time for producing one printed board. Further, the component out time is obtained by the following equation. -Component outage time = Actual time when one printed board unit has passed + Time until the reel member is replaced.

For example, when calculating the component outage time, the current time = 13: 00, the number of remaining parts of the reel member =
Parts quantity required for 100 printed circuit board units =
25, tact time = 1 minute, parts out time = 13: 00+ (100/25) × 1 =
13:04 The component out time at this time is 13:04. Further, assuming that the time when one printed board unit has passed is 13:02 and the number of remaining parts of the reel member is 75 pieces, the following is obtained: 13: 02+ (75 ÷ 25) × 1 = 1
3:05 The component out time at this time is 13:05. On the other hand, when one printed board unit passes at 13:02 and the remaining number of components of the reel member = 74 (the number of picked-up components includes one error), the time of component outage = 13: 02+ ( 74 ÷ 25) × 1 = 1
3:04 The component out time at this time is 13:04.

In short, the prediction of the part shortage time is obtained by adding the logical time until the reel member is replaced to the actual production time each time one printed board unit is produced. Further, the logical time until the reel member is replaced is obtained from the data on the remaining number of parts of the reel member.

By the way, the performance / feedback processing section 39 determines the mounter name (machine) to be replaced one by one in the order of the replacement time, the mounter lane number (lane number), and the replacement time. Are digitally displayed by the display unit 41 so that they can be seen at a glance from a distance.

Further, the performance / feedback processing section 39 can also use an audio output section 40 to notify by voice that a replacement will occur before a predetermined time before the member replacement time. One minute before, for example, it will signal that an exchange will occur soon.

Next, confirmation of replenishment parts will be described in detail.

The bar code information given to the reel member includes a reel ID, a part drawing number, a winding direction, a delivery code, and the like. The exchange confirmation unit 45 includes a barcode reader. Further, the replacement confirmation unit 45 has a function of comparing the reel member that has become empty and the reel member that is newly mounted on the mounter when parts run out. By reading the code information and comparing it with the empty reel member based on the data of the mounter performance management unit 34,
Check the winding direction and delivery code to confirm that parts can be replenished without mistake.

Further, when executing the above-described parts replenishment check processing, the replacement confirmation section 45 displays, for example, on the display section 41 provided for each line via the results / feedback processing section 39 as shown in FIG. Notify the operator on the exchange confirmation screen. The notification is also made by voice using the voice output unit 40.

The parts supply management system in the production of a printed board unit according to the present embodiment includes the inventory management unit 3
The reel member having the same part drawing number, winding direction, and output code managed in 3 allows the mounter to be mounted to be arbitrarily specified.

In step S01, the production management department drafts a production plan including the production model to be produced and the number of products to be produced from the data held in the server 31 according to the order receiving situation.

In step S02, output data, which is a part to be used including a component corresponding to a production model required for a production plan, is created from data held by the server 31.

In step S03, the worker in the parts management section transports the parts to the manufacturing section. Next, step S
At 04, the worker in the manufacturing department receives the part and enters the warehouse in the manufacturing department.

In step S05, the production plan materializing section 32 receives the production plan drafted by the production management department.
Further, in step S06, the material output data created by the production management department is received.

In step S07, the manufacturing department considers the instruction of the production management department and the efficiency of the production line provided in the manufacturing department based on the data of the inventory management part 33 of the production plan materializing part 32 and the data of the mounter information management part 35. To rebuild the production plan.

In step S08, the actual / feedback unit 39 sets the inventory management unit 3 of the production plan embodying unit 32.
The data of No. 3 is corrected in a timely manner (for example, every week), and the stock of parts held by the manufacturing department is recalculated. In this modification, if the production quantity is affected due to a shortage of parts, the server 31 of the production management department is notified that parts supply arrangement is necessary.

In step S09, the allocation processing section 36 of the production plan materializing section 32 performs a temporary allocation based on the re-planned production plan, and determines whether or not production is possible with the re-planned production plan. Check with the parts held in.

In step S10, the production availability judging section 37 of the production plan materializing section 32 calculates the number of producible parts based on the contents of the parts held in the manufacturing department, and if production is impossible, it is necessary to divide the production lot. Is determined. If lot division is required, the process returns to step S07 to correct the production plan. If you don't need lot splitting,
Proceed to step S11.

In step S11, the production plan embodying unit 32 calculates the estimated production completion time of the re-planned production plan, predicts the production end time, and confirms the execution schedule of the next production plan.

In step S12, the work plan simulation section 42 receives the production plan re-established by the production plan embodying section 32, and checks the simulation result of the production completion time. That is, it is confirmed that there is no problem in the delivery date and the flow with the next process. If there is a problem, step S11
Return to If there is no problem, go to step S13.

In step S13, the work plan simulation section 42 predicts a stoppage of a component part stop of a mounter constituting a production line when the production plan re-planned by the production plan materializing section 32 is executed.

In step S14, the production plan embodying unit 32 prints a list for preparation. For example, it outputs a necessary parts list, a replenishment parts list, a missing parts list for re-parts delivery, and the like. At this time, the stock management unit 33 of the production plan materializing unit 32 stores the reel ID managed by the stock management unit 33, the part drawing number, A material is output after an identification code for identifying a direction and a material output code is given.

In step S15, the operator arranges parts handled on the production line that has been dispatched in accordance with the production plan.

At step S16, the operator prepares, for example, each mounter constituting the SMT line. That is, the supply parts are set on a jig (attached to a cassette) based on the mounter data, and a test operation or the like is performed.

At step S17, the worker starts production. That is, the operation is started from the mounter whose preparation is completed.

In step S18, the result / feedback processing section 39 notifies the worker of the component exhaustion and the replenishment time at each mounter. For example, which line and which part needs to be replenished is notified.
Notification is made by digital display or voice.

In step S19, the operator prepares a part to be replenished in a jig in advance before the part runs out.

In step S20, it is determined whether the mounter has stopped due to lack of parts. If it has not stopped, the process returns to step S17, and if the mounter has stopped due to lack of parts, the process proceeds to step S21.

In step S21, the exchange confirmation unit 45
Reads the identification code of the reel member newly mounted on the mounter, compares the empty reel member based on the data of the mounter performance management unit 34 with the reel member newly mounted on the mounter, Check the winding direction and the output code to confirm that the replenishment parts have been set correctly. At this time, the operator is notified by the display unit 41 on the exchange confirmation screen shown in FIG. The notification is also made by voice using the voice output unit 40.

In step S22, parts replenishment is performed. At this time, the replacement confirmation unit 45 notifies the identification code of the reel member to be replenished to the production plan embodying unit 32 and registers the component information in the mounter performance management unit 34. Also, the component information of the reel member to be replaced, which is registered in the mounter performance management unit 34, is discarded.

In step S23, the production result counting section 43 counts the number of sheets produced for the work progress of the production line, and the work plan simulation section 42 displays and notifies the progress information.

In step S24, the production result counting section 43 determines whether or not the printed board unit has passed in each mounter based on a notification from each detection section. If the printed board unit has passed, the process proceeds to step S25. If the printed board unit has not passed, the process returns to step S17.

In step S25, the production result counting unit 43 acquires the result data of the component consumption of the mounter. That is, every time one printed circuit board unit is produced, the part consumption actual data including the number of picked-up parts is acquired, notified to the work plan simulation part 42, and the data of the mounter actual management part 34 is updated.

In step S26, the work plan simulation section 42 calculates the reel member replacement scheduled time based on the actual time when the printed board unit has passed, and determines whether the reel member replacement scheduled time needs to be corrected.
That is, if the actual component replacement work time does not match the scheduled reel member replacement time, the process returns to step S18, where the reel member replacement is corrected to the actually performed time, and the second and subsequent reel member replacement scheduled times are set. Display at the corrected time. If it is not necessary to correct the reel member replacement scheduled time, the process proceeds to step S27.

In step S27, the work plan simulation section 42 determines whether a delay occurs in the production plan. At this time, a reel member having the same part drawing number, winding direction, and output code managed by the inventory management unit 33 is
The mounter to be mounted can be arbitrarily specified, and the reel ID of the remaining reel member is notified to the inventory management unit 33. In addition,
If the production quantity is delayed due to a shortage of parts, the process returns to step S07, and if it is necessary to change the allocation order, the content of allocation is arbitrarily changed. Also,
If there is no need to change the allocation order, step S28
Proceed to.

In step S28, it is determined whether the production is completed. If the production is not completed, the process returns to step S07. If completed, the process ends.

As described above, according to the present invention, the following effects can be expected.

By providing simulation means for predicting a part-out time on the basis of actual machine part consumption data acquired by a progress collecting means for obtaining production progress information of a production line, data for predicting a part-out time is provided. As a result, the actual consumption data of the parts of the machine can be used. Since the actual component consumption data of the machine is not a logical value but an actual value, it is possible to reduce an error when estimating a component exhaustion time.

Further, the progress collecting means sets one printed board unit in response to a notification from a detecting means for detecting passage of a printed board unit installed corresponding to each machine.
By acquiring the actual consumption data consisting of the number of parts picked up by each machine every time a sheet is produced, the number of parts picked up is the number of parts mounted on the printed board unit and the number of errors that could not be mounted on the printed board unit. , The actual component consumption data of the machine can be true component consumption data.

Further, the simulation means receives the component consumption actual data of the machine from the progress collecting means, calculates the number of remaining parts of each reel member mounted on the machine, and calculates the remaining number of parts. By converting to time, the number of remaining parts is calculated from the actual data of the parts consumption of the machine. Therefore, the number of remaining parts is an accurate number of remaining parts based on the actual results, and it is possible to predict a part-out time with a small error.

Further, when calculating the remaining number of components of each reel member mounted on the machine, the simulation means receives the component consumption actual data every time one printed board unit is produced, and is mounted on the machine. By calculating the remaining number of parts by subtracting the actual consumption of the component from the total number of components of each reel member each time, and calculating the remaining number of components, the prediction based on the actual performance is performed every time one printed board unit is produced when estimating the component outage time. Since the part shortage time is calculated from the remaining number of parts, the accuracy of the part shortage time can be improved.

Further, when estimating the time at which a reel member will run out, the simulation means calculates the remaining number of components of a single reel member mounted on the machine at the actual time when one printed board unit has passed. Dividing by the number of parts required to produce one unit, and adding a value multiplied by the tact time to produce one printed board unit, when predicting the time at which parts of a reel member will run out, Since the calculated time is calculated from the actual time when one printed circuit board unit was produced immediately before and the part-out time based on the true remaining number of parts, the predicted part-out time of the reel member is improved in accuracy, and the accurate part-out time is improved. It can be.

Further, by providing a mounter performance management unit for updating the number of parts in the reel of each reel member mounted on the machine every time one printed board unit is produced, every time one printed board unit is produced. The true remaining number of parts and the number of errors of the reel member based on the location data can always be grasped.

Further, when the component runs out, an empty reel member based on the data of the mounter performance management unit
Compared with the reel member newly mounted on the machine, the parts drawing number, winding direction, and output code are checked, and replacement confirmation means is provided to confirm that parts can be replenished without error. By providing the check function of (1), the parts replenishment operation can be reliably performed by preventing operation errors.

Further, when the replacement confirmation means checks the replenishment of parts, a notification means for notifying the worker by a display screen and / or voice is provided, so that the operator can be surely instructed or notified when replenishing parts. Therefore, the parts replenishment work can be ensured.

Further, the notifying means corrects the data of the stock management section for managing the reel members held by the manufacturing section at the time of executing the production plan, and notifies the production management section to prompt the parts replenishment. As a result, it is possible to prevent an influence such as a delay on a production plan due to a shortage of parts occurring in the manufacturing department.

Further, a reel member having the same part drawing number, winding direction, and output code managed by the inventory management unit can be arbitrarily designated as a machine on which to mount, so that the manufacturing department holds it. Since the reel member having the same part drawing number, winding direction, and output code does not specify the machine to be mounted, the reel member can be diverted at the time of work planning. In addition, an optimal reel member can be replenished at the time of component replenishment, and the number of replenishments can be reduced. Further, it is not necessary to search for a reel member when replenishing parts.
