Furthermore, use conditions of the dual feeder and the reel are managed and in consideration for use and non-use conditions, the component arrangement of the next production model is determined.

Description

  The present invention relates to a method (algorithm) for determining the arrangement of a dual feeder and an electronic component in an electronic component mounting machine (hereinafter referred to as a mounter) to which a dual feeder is applied, and an apparatus therefor. Technology.

  When mounting electronic parts on a printed circuit board using a mounter, when switching production models, it is necessary to replace the electronic parts set on the mounter according to the electronic parts used on the printed circuit board. This is called setup work. The mounting work of the mounter is a manual work, and all types of electronic components used for the printed circuit board are manually set. In recent years, printed circuit boards have been improved in performance and functionality, and in order to achieve high performance and functions, the types of electronic components used on each printed circuit board have increased, and accordingly, setup time has increased. Is also increasing.

  In addition, when setting electronic components on the mounter, electronic components are set on a jig called a feeder, and the feeder is set on the mounter. In order to cope with the increase in the types of electronic components, the conventional feeder has only one type of electronic component. There is a mounter to which a “dual feeder” that can set two types of electronic components is applied to one feeder while it cannot be set.

The electronic component mounting work, dual feeder outline, and setup work by a conventional mounter will be described with reference to FIGS.
FIG. 2A is a schematic view showing the mounter 1 as viewed from above. The mounter 1 is supplied with a dual feeder 3 for setting electronic parts, a bank 2 for setting a plurality of dual feeders 3, a transport rail 7 for transporting a printed circuit board 11, a suction nozzle 9 for sucking parts. A recognition camera 10 for recognizing the position of the component, a head unit 8 in which the suction nozzle 9 and the recognition camera 10 are integrated, a Y-axis rail 5 for moving the head unit 8, and an X-axis rail 6 are configured.

First, as a configuration in which the electronic component 12 is set, there is a bank 2 in which a plurality of dual feeders 3 on which the electronic component 12 is set can be set. A position where the dual feeder 3 in the bank 2 is set is referred to as a lane 4. The dual feeder 3 in which the electronic component 12 is set is set side by side in the lane 4 of the bank 2, and the bank 2 in which the dual feeder 3 is set is set in the mounter 1.
Next, as a configuration for supplying the printed circuit board 11, there is a transport rail 7, the printed circuit board 11 is transported into the mounter 1 along the transport rail 7, and the printed circuit board 11 is supplied to a predetermined position.

Next, as a configuration for mounting the electronic component 12 at the electronic component mounting position 13 on the printed circuit board 11, there are a Y-axis rail 5 and an X-axis rail 6 for moving the head unit 8.
The head unit 8 includes a recognition camera 10 that recognizes the position of the component and a suction nozzle 9 that sucks the electronic component 12. The head unit 8 automatically moves to the upper part of the electronic component 12 set on the dual feeder 3 along the Y-axis rail 5 and the X-axis rail 6, and the electronic component 12 is adsorbed and raised by the adsorption nozzle 9. Next, along the Y-axis rail 5 and the X-axis rail 6, the head unit 8 automatically moves to the upper part of the electronic component mounting position 13 of the printed circuit board 11, and the suction nozzle 9 descends, and the electronic components of the printed circuit board 11 are moved. The electronic component 12 is mounted at the mounting position 13.

  FIG. 2B shows the details of the supply form of the electronic component 12 set in the dual feeder 3. Generally referred to as “reel parts”, the electronic parts 12 are stored side by side in a carrier tape 21, and the reel 20 is configured to wind and store the carrier tape 21. The electronic component 12 is set in the dual feeder 3 in units of the reels 20. The reel 20 stores one kind of electronic component in units of thousands or tens of thousands.

  3 (a) and 3 (b) show a conventional feeder 30. FIG. The feeder 30 has one mechanism for setting the reel 20, and includes a component suction portion 31 that is a position where the electronic component 12 is sucked by the suction nozzle 9. One reel 20 can be set to the one feeder 30. As a setting procedure, first, the reel 20 is set in the feeder 30 and the carrier tape 21 is pulled out. Next, the leading portion of the electronic component 12 housed in the carrier tape 21 is pulled out and fixed to the component suction portion 31 at the tip of the feeder 30.

  4 (a) and 4 (b) show the dual feeder 40. FIG. The dual feeder 40 has two mechanisms for setting the reel 20 and includes an A-side slot component suction portion 41 and a B-side slot component suction portion 42 that are positions where the electronic component 12 is sucked by the suction nozzle 9. Two (two types) reels 20a and 20b can be set to one dual feeder 40. The set position is identified by the designation of the A side slot and the B side slot. As a setting procedure, the reel 20a is set on the dual feeder 40, and the carrier tape 21a is pulled out. Next, the carrier tape 21a is pulled out along the A-side slot of the dual feeder 40, and the leading portion of the electronic component 12a is pulled out and fixed to the A-side slot component suction portion 41 of the dual feeder 40. Next, the reel 20b is set on the dual feeder 40, and the carrier tape 21b is pulled out. Next, the carrier tape 21b is pulled out along the B side slot of the dual feeder 40, and the leading portion of the electronic component 12b is pulled out and fixed to the B side slot component suction portion 42 of the dual feeder 40.

  The advantage of the dual feeder 40 is that two (two types) of electronic components 12a and 12b can be set for one feeder, and the number of types of components that can be set can be increased even if the size of the mounter 1 is the same. . As a demerit of the dual feeder 40, when the parts of the A side slot and the B side slot are exchanged at the time of switching the production model, the work of removing the reel 20 from the dual feeder 40 occurs, which takes a long time. In the case of the conventional feeder 30, if the feeder 30 is replaced in the lane 4 in the bank 2 without removing the reel 20 from the feeder 30, the same operation as described above is performed. In the case of 40, work cannot be performed unless the reel 20 is removed from the dual feeder 40, so work efficiency is poor. Further, the dual feeder 40 has a complicated internal mechanism, and is a mechanism for electrically feeding the carrier tape 21 along the A side slot and the B side slot. Therefore, every time the reel 20 is replaced, it is necessary to perform the work after the dual feeder 40 is set in the dedicated power supply device, which takes work time. That is, as compared with the conventional feeder 30, it takes two to three times longer to replace one reel of the dual feeder 40.

  FIG. 5 shows a setting operation of the reel 20 to the dual feeder 40. An operation of setting two reels 20 (two types) to the dual feeder 40 is performed. For example, when there are 100 types of electronic components 12 mounted on the printed circuit board 11, it is necessary to set 100 types of electronic components 12 to the dual feeder 40. That is, it is necessary to prepare 50 sets of the dual feeder 40 and perform the setting work manually. For example, when it takes 1.5 minutes to set one reel 20 to the dual feeder 40, it takes 150 minutes (2.5 hours) to set 100 kinds of electronic components. There is a problem of spending a lot of time. Furthermore, it is sufficient that all types of electronic components 12 can be prepared during the setup work. However, when the work is being used in another work or another mounter, the work of setting the reel 20 on the dual feeder 40 can be completed. However, there is a problem that it is necessary to perform work after waiting for completion of the use of the reel 20 in other work and other lines, and the work time of the setup work is further increased.

  FIG. 6 shows a setting operation of the dual feeder 40 on which the reel 20 is set to the bank 2. The dual feeder 40 on which the reel 20 is set is set side by side on the lane 4 of the bank 2. The bank 2 in which the dual feeder 40 is set is prepared and the setup work is completed. When the production model of the mounter 1 is switched, the bank 2 is set in the mounter 1 at a time, and the mounter part mounting work is started. That is, during the component mounting work of the mounter 1, the dual feeder 40 in which the reel 20 used in the next production model is set is prepared in advance, and further set in the bank 2, so that the mounter 1 can be mounted. Setup work can be performed without stopping.

  FIG. 7 is a flowchart showing a component mounting operation by the conventional mounter 1. First, the production model NC program is read, and the part arrangement of the bank 2 is determined (S1). The production model NC program is data for instructing information necessary for mounting the electronic component 12 on the printed circuit board 11, and is composed of a component ID, X, Y coordinates, mounting angle, and circuit symbol. In addition, the component placement of the bank 2 is determined by automatic processing on a personal computer using an optimum lane placement determination program provided by the mounter manufacturer.

Next, referring to the personal computer screen or printed paper for the determined component arrangement of bank 2, the reel 20 is manually set on the dual feeder 40 (S2). Next, the dual feeder 40 having the reel 20 set manually is arranged and set in the lane 4 of the bank 2 (S3). This completes the setup work.
Next, the bank 2 in which the dual feeder 40 is set manually is set on the mounter 1 at once (S4).

Next, the production model NC program is read and the electronic component mounting work is started (S5). Next, the printed circuit board 11 is automatically transported into the mounter 1 along the transport rail 7 (S6). Next, the head unit 8 moves to the component suction portion of the dual feeder 40 along the Y-axis rail 5 and the X-axis rail 6 (S7).
Next, the electronic component 12 is recognized by the recognition camera 10 (the position of the suction nozzle is adjusted by recognizing the exact position of the component), and the electronic component 12 is sucked to the suction nozzle 9 from the dual feeder 40 (S8). . Next, the head unit 8 moves to the electronic component mounting position 13 on the printed circuit board 11, and the electronic component 12 is mounted on the electronic component mounting position 13 on the printed circuit board 11 (S9). This repeats and automatically performs the mounting operation until all the electronic component mounting work on the printed circuit board 11 is completed (S10).

  After all the electronic components 12 are mounted, the printed circuit board 11 is unloaded from the mounter 1 (S11), the next printed circuit board 11 is loaded into the mounter 1, and the electronic component mounting operation is repeated. When the electronic component mounting work for all the printed boards 11 is completed, the electronic component mounting work is finished (S12). When the electronic component mounting operation is completed, the bank 2 in which the dual feeder 40 is set is removed from the mounter 1 by hand (S13). The removed dual feeder 40 may be used for the next production model, and when not used, the reel 20 is manually removed from the dual feeder 40 and stored in a storage shelf.

  FIG. 8 shows the relationship between setup time and net time when one production model is mounted with an electronic component using a mounter. The work time of the electronic component mounting work to which the mounter is applied is represented by a setup time (d) 50 and a net time (n) 51. The setup time (d) 50 is an operation from setting the reel 20 of the electronic component 12 used in one production model (hereinafter referred to as a lot) to the dual feeder 40 and setting the dual feeder 40 to the bank (storage stand) 2. Represents time.

  The net time (n) 51 is a work time in which the mounter 1 automatically mounts the electronic components 12 on all printed circuit boards 11 in one lot after the bank 2 on which the dual feeder 40 is set is set on the mounter 1. Represents. That is, the time when the mounter 1 automatically mounts the electronic component 12 is defined as the net time (n) 51. One lot of electronic component mounting work time (T) has a relationship of setup time (d) + net time (n).

  In the case of a work form in which a high-performance, high-performance printed circuit board with many types of electronic components 12 used for each printed circuit board 11 is produced with a production plan of a small lot (equivalent to 10-20 sheets / lot) The time (d) 50 is long because there are many types of electronic components 12 to be used, and the net time (n) 51 is a time required for mounting the electronic components using the head unit 8 in which the mounter 1 automatically moves a small number of lots at high speed. Because it does, it becomes a relatively short relationship. In other words, the setup time (d) 50 >> the net time (n) 51, and the ratio of the setup time (d) 50 is very large.

  As shown in FIG. 9, the lot that was the setup time (d) 52, the net time (n) 51, and the electronic component mounting work time (T 0) is reduced to the setup time (d) by reducing the setup time (d) 52. ) 53, net time (n) 51, and electronic component mounting work time (T1), shortened time (T2) = (T0) − (T1). That is, it becomes possible to start the work of mounting the electronic component of the next lot in advance by the amount shortened by the shortening time (T2).

10 and 11 are time charts for each lot of component mounting work by the mounter. The horizontal axis shows the working time (t) for one day. dn represents the setup time of lot n, and nn represents the net time of lot n. As shown in FIG. 10, the mounter is operated so that the net work of the next lot is not generated by ending the setup work of the next lot until the net work of the current lot is completed as shown in FIG. 10. Perform operations to migrate to. This method is called a sequential setup method. In FIG. 10, after the net time (n1) of the lot 1 is completed, the bank where the setup operation of the lot 2 is completed is set on the mounter, and the net time (n2) of the lot 2 is started. The setup operation of lot 3 is performed during the net time (n2) of lot 2. The setup operation for lot 3 is an operation for resetting the parts used in lot 1 so that they can be used in lot 3.
In the example of FIG. 10, the setup operation is sequentially performed on the n + 2nd lot for the bank and dual feeder used in the net operation of the lot n, but from the lot n, the n + 3th lot, Alternatively, there is a form in which the setup is sequentially performed on the (n + 4) th lot. However, in that case, it is necessary to prepare multiple banks that have completed setup work in advance, and if there is not enough room for the number of banks and dual feeders, and the number of reels of electronic parts, setup work The problem that it cannot be done occurs.

  When the sequential setup operation of FIG. 10 is performed for the n + 2th lot and the setup time is long, for example, the relationship (d3)> (n2) is established, and the net operation of lot 2 is completed. The setup work is not completed by this time, and a waiting time 60 due to the stop of the mounter occurs. Similarly, when the setup operation is sequentially performed on the n + 3th lot in the sequential setup form, for example, when (d4)> (n2) + (n3), the waiting time 60 due to the stop of the mounter is similarly obtained. Will occur. When the waiting time 60 due to the stop of the mounter occurs, there arises a problem that the number of production work per day (hereinafter referred to as throughput) decreases and work efficiency deteriorates. As described above, in an operation mode in which a high-performance and high-performance printed circuit board is produced with a production plan of a small lot, the net operation time of the previous lot is completed because of the setup time (d) >> net time (n). At this point, a state occurs in which the setup work for the next electronic component mounting target lot is not completed. Therefore, shortening the setup time (dn) is the most effective measure for improving the throughput.

  If the setup time (dn) is shortened as shown in FIG. 11, the generation of the waiting time 60 due to the mounter stop can be suppressed, and furthermore, the electronic component mounting work time per one lot (setup time + net time) is also shortened. When compared with the number of lots that can be worked within a predetermined range of work time (tm) before shortening the setup time (dn), the work that could only be done up to lot n is within the same work time (tm) The number of lots that can be worked like the preceding lots n + 1 and n + 2 can be increased, and the throughput is improved.

  12 and 13 show the relationship between the arrangement of the dual feeder 3 in the lane 4 in the bank 2 and the net time (n). As shown in FIG. 12, when the mounter 1 is viewed from above, when the distance from the electronic component mounting position 13 of the printed circuit board 11 to the electronic component 12 of the component adsorption portion on the dual feeder 3 is short, the electronic component Since the time for moving 12 to the electronic component mounting position 13 is short, the net time (n) is short. That is, the net time (n) can be shortened by arranging the electronic component mounting position 13 (X coordinate) −the electronic component position 12 (X coordinate) of the component suction portion = minor (Min). As shown in FIG. 13, when the electronic component mounting position 13 on the printed circuit board 11 is arranged so that the distance from the component suction portion on the dual feeder 3 to the electronic component 12 is long, the electronic component 12 is placed in the electronic component mounting position 13. Since the time to move to becomes longer, the net time (n) becomes longer. That is, if the electronic component mounting position 13 (X coordinate) −the electronic component 12 (X coordinate) of the component suction portion = large (Max), the net time (n) becomes long. That is, when determining the arrangement of the dual feeders 3 in the lanes 4 in the bank 2, it is necessary to arrange components that prevent the net time (n) from becoming long in consideration of the above contents.

  Further, as a factor that the net time (n) becomes long, there is a case where the net time (n) becomes long due to frequent occurrence of parts replacement work due to the out of parts of the reel 20 set in the dual feeder 3. This is because, when the electronic component 12 of the reel 20 set in the dual feeder 3 within the net time (n) disappears during the mounting operation of the component, an operation of replacing the reel 20 of the dual feeder 3 occurs. Since the mounting operation of the mounter is stopped during the replacement work, if the replacement work frequently occurs, there arises a problem that the net time (n) becomes long. In other words, in order to prevent frequent reel replacement work during mounting work, the number of electronic components 12 remaining in the reel 20 relative to the number of electronic components 12 used in one lot is taken into consideration at the stage of the setup work. The reel 20 needs to be arranged. Thereby, the increase in the net time (n) due to frequent parts replacement work can be suppressed.

  However, as described above, the net time (n) is short because the mounter performs high speed and automatic component mounting work for a small number of lots, so that the setup time (d) >> net time (n) is satisfied. For the purpose of improving the overall throughput, the effect of shortening the net time (n) is small. Therefore, when comparing the shortening of the setup time (d) and the minimization of the net time (n), the electronic component mounting by the mounter 1 is performed by placing components with priority on the setup time (d) minimizing. It is possible to improve the overall throughput of work.

  As background art of this technical field, there is JP-A-2002-232190 (Patent Document 1). This publication aims to provide a feeder arrangement data creation apparatus and feeder arrangement data creation method in an electronic component mounting apparatus capable of creating feeder arrangement data based on an appropriate optimization processing result. In a feeder arrangement data creation device for creating feeder arrangement data in a mounting apparatus in which a double feeder capable of supplying types of electronic components is arranged in a component supply unit, a combination of electronic component types is not fixedly set in advance. Enter the maximum number of unconstrained feeders defined as the upper limit number allowed to use the constrained tape feeder, and display the estimated cycle time calculated based on the input maximum number of unconstrained feeders. Set conditions flexibly to enable flexible optimization and whether optimization calculation results are appropriate Can be easily determined, it is possible to perform proper optimization come true optimization purposes. "Is described as (see Abstract).

  Moreover, there exists Unexamined-Japanese-Patent No. 2009-111106 (patent document 2). This publication states that “the total production time is shortened when optimizing the feeder arrangement at the time of current production based on the cluster information indicating the feeder arrangement optimized before the current production. Included in the cluster information. For feeders, cluster optimization that does not replace feeders with fixed positions, and cluster information inheritance optimization that replaces feeders so that the feeders of the same parts are gathered, even for feeders included in the cluster information, are performed. In comparison, the feeder set information is created using the feeder arrangement having the shorter total production time including the feeder replacement time ”(see the summary).

JP 2002-232190 A JP 2009-111106 A

  The problem to be solved is that in the electronic component mounting work by the mounter to which the dual feeder is applied, the dual feeder has a problem that it takes time to replace the reel as compared with the conventional feeder. For this reason, the setup time of a printed circuit board having a large number of types of electronic components tends to increase. In the work mode in which electronic parts mounting work for printed circuit boards with a large number of electronic parts is done with a small lot production plan, if the setup time is long, the setup work for the next production model is completed by the end of the net work of the previous production model Therefore, the waiting time for the mounter to stop is generated. Furthermore, because the dual feeders and reels required for setup work are not managed in other mounters, the dual feeder or reel is being used by other mounters during manual setup work. The work could not be completed, causing the setup work time to be lengthened.

  In addition, since the number of remaining parts of the reels set in the dual feeder is not managed, if multiple reels with fewer parts remaining than the number of electronic parts used in the next production model are set during setup work, In addition, the reel replacement work of the dual feeder due to parts shortage frequently occurs. As described above, the reel replacement operation in the dual feeder takes time, and if the reel replacement operation occurs frequently, the stop time of the mounter increases and causes a reduction in the operating rate.

  In order to solve the above problems, in the present invention, in the electronic component mounting work by the mounter to which the dual feeder is applied, the component placement determination in the case of performing the setup work of the next production model by using the dual feeder placement in the bank of the previous production model. In the method, (1) a step of continuously placing and fixing fixedly arranged reel parts set in the dual feeder used in the previous production model in the fixed placement information lane, and (2) preproduction If it is possible to move and arrange the lanes for each dual feeder without removing both parts already set on the dual feeder used in the model, placing and confirming with the second priority, and ( 3) If both parts already set with unused registered dual feeders can be placed in the lane without removing them, place them at the third priority and confirm. (4) Without removing the one-sided parts that have been set in the dual feeder used in the previous production model, set the reel parts in the empty slot on the opposite side and place each dual feeder in the lane. If possible, place and confirm at the 4th priority, and (5) set the one-sided part in the dual feeder used in the previous production model in the opposite slot without removing it. In the next production model that has already been completed, unused reel parts are removed, new reel parts are set, and when it is possible to place the dual feeders in the lane, placing and confirming with the fifth priority, ( 6) A process of setting a reel component in a slot on both sides for an empty dual feeder and placing and confirming with a sixth priority when the dual feeder can be placed in a lane. Yes And a component arrangement determining method comprising Rukoto.

  In order to solve the above problems, in the present invention, in the component placement determination method, prior to the component placement determination process, the mounting operation of all the components of the next production model on the printed circuit board by the mounter is fastest. A step of tentatively determining the component arrangement on the lane, the component arrangement in each of the first to sixth steps being the same as the target component arrangement, with the provision of the component arrangement on the tentatively determined lane The component placement determination method is characterized in that it is placed in a lane or a nearby lane.

  Further, in order to solve the above-mentioned problems, in the present invention, in the electronic component mounting work by the mounter to which the dual feeder is applied, the parts when the next production model is set up by utilizing the dual feeder arrangement in the bank of the previous production model. A component placement determination device that determines the placement and outputs the next production model placement information includes a control unit, a storage unit, an input unit, a display unit, and a communication unit, and the storage unit has a print Next-production model NC program storage area for instructing information necessary for mounting electronic components on the board, and fixed arrangement for storing part ID information of reel parts set in the dual feeder for the fixed arrangement lane Information storage area, registered dual feeder information storage area for storing registered dual feeder information, and information on remaining number of parts in reel identified by part ID Reel part remaining number management information storage area to be stored, lane arrangement in bank by production machine type, and production machine type arrangement information storage area for storing part ID information of reel parts set in the dual feeder, The control unit executes an optimal lane allocation determination program of a known technique to temporarily determine the optimal lane allocation in order to minimize the mounter driving time, and an intra-bank dual feeder of the previous production model The process of deciding the part placement of the next production model by diverting the placement is classified into six work element patterns for the part placement change work in the bank, the priority order is assigned to each work element pattern, and the optimum lane Determine the placement of parts for the next production model that determines the placement from the parts that can be placed by the dual feeder in each work element pattern according to the priority order with the goal of placement It was configured with a door.

  The present invention has a long setup time by minimizing the setup time when working with a high-performance, high-performance printed circuit board in a small lot production form in an electronic component mounting work by a mounter to which a dual feeder is applied. Since the waiting time when the mounter due to the cause is stopped can be prevented, and the time required for the entire electronic component mounting operation can be shortened, there is an effect of improving the throughput of the electronic component mounting operation. Furthermore, by managing the usage state of the dual feeder and the reel, there is an effect that it is possible to avoid the waiting for the setup work due to the inability to prepare the dual feeder and the reel in the setup work and to suppress an increase in the setup time.

  Further, by determining the reels to be set in the dual feeder in consideration of the remaining number of reel parts, there is an effect of suppressing an increase in mounter stop time due to frequent reel replacement work.

The registered dual feeder 40 assigns an ID number to each registered dual feeder 40, and performs state management (used / unused state) for each ID number. Work No. The approximate work time for 3 is T * 6 seconds / time. In selecting a reel to be set in the registered dual feeder 40 prepared in advance, the use frequency of the reel is investigated from the production results and the reels with a high use frequency are preferentially arranged.

The reel 20c is arranged. The dual feeder 40 is removed from the lane 4 in the bank 2 [2], and in the next production model, the unused reel 20a is removed from the dual feeder 40 [3]. The new reel 20c is set [4] in the slot from which the unused reel 20a is removed, and the dual feeder 40 with the reel 20c set is set [5] in the lane 4. The reel 20b already set in the slot on the opposite side where the new reel 20c is set is not removed. Work No. The estimated work time for 5 is T * 16 seconds / time.

  Work No. 6 is to arrange new reels (20c, 20d) on the slot A side and the slot B side of the dual feeder 40 from the state where nothing is prepared. A dual feeder 40 in which nothing is set on the slot A side and the slot B side is prepared, and a new reel 20c is set [4] on the slot A side, and then a new reel 20d is set [4] on the slot B side. The dual feeder 40 in which the new reel parts (20c, 20d) are set is set to the lane 4 [5]. Work No. The estimated work time for 6 is T * 18 seconds / time.

  In the present invention, the work time for each work element is the work number. 1 <Work No. 2 <Work No. 3 <Work No. 4 <Work No. 5 <Work No. 6 in the process of determining the part placement of the next production model from the part placement of the previous production model. Work No. 1 in order from the condition of 1. The part placement determination process up to 6 is executed, and by placing all the parts, the part placement of the next production model with the shortest setup time is determined.

  FIG. 16 shows the part placement priority for determining the part placement of the next production model. The part allocation allocation priority of the item represents the priority when determining the part arrangement in the process of determining the part arrangement of the next production model. Parts in the order of priority [1] to priority [6] Placement determination processing is performed. The function name of the item is obtained by adding a name to the priorities [1] to [6]. The numbers [1] to [6] are the work numbers described in FIGS. No. 1 to work no. Corresponds to 6 work elements.

The previous production model dual feeder A side and the previous production model dual feeder B side of the item indicate the slot state of the dual feeder in the previous production model, and “empty” indicates a slot in which no parts are arranged in the previous production model, “ "Used" is the part used in the previous production model, the slot where the parts used in the next production model are placed, "Unused" is the part used in the previous production model, and parts not used in the next production model are placed Represents a slot. Further, “◯” in the figure indicates that a new reel is arranged in the slot.
The optimal lane placement of the item indicates that the component placement is performed in consideration of the placement of the dual feeder in the lane or the vicinity of the lane where the net time is the shortest from the electronic component mounting position on the printed circuit board and the lane position of the bank. ing.
The management of the number of remaining parts in the item represents that the parts are placed in consideration of the state of the remaining number of reel parts when a new reel is placed.

  In the present invention, when the part placement determination process is performed from the priority order [1] and the parts placement of all reel parts used in the next production model is not completed, the priority order [2] to the priority order [ 6] The part placement process is continued in the order of [6] and the parts placement of all reel parts is completed, so that the part placement of the next production model with the shortest setup time can be determined. Further, the increase in the net time can be suppressed by performing the component placement determination process in consideration of the optimal lane placement and the remaining component number management. A detailed processing flow will be described with reference to FIGS.

  FIG. 17 is a diagram for explaining the input information to the next production model arrangement determination process in the next production model component arrangement determination unit 113 and the delivery of the output information. As input information (Input), fixed placement information 124 that stores information for fixed placement of dual feeders in a bank, previous production model placement information 127 that stores in-bank part placement information of previous production models, and registered dual feeder information There is stored registered dual feeder information 230 (125), and reel component remaining number management information 240 (126) storing component remaining number information in the reel. The registered dual feeder information 230 and the reel component remaining number management information 240 are information for commonly managing the registered dual feeder and the reel used / unused status information in other mounters determined by the other component placement determining device 220. The information is referred to during the next production model arrangement determination process 113. As a result, when there is a registered dual feeder or reel that is being used by another mounter during execution of the next production model arrangement determination process, the registered dual feeder or reel is not selected for the component arrangement of the next production model.

The input information (Input) includes the next production model NC program 123. The next production model NC program 123 indicates the electronic component mounting position information of the printed circuit board of the next production model, and stores information on the component ID, circuit symbol, X coordinate value, Y coordinate value, and mounting angle.
The input information (Input) is read, the next production model arrangement determination process 113 is performed in accordance with the priority order described with reference to FIG. 16, and the next production model arrangement information 127 is output (Output). The next production model arrangement information 127 is output and referred to on a personal computer screen or paper, and the setup work is performed manually based on the information. Next, the net work is performed, and the used / unused state of the registered dual feeder and the reel after the net work is finished is sent to the registered dual feeder information 230 and the reel part remaining number management information 240 to be used / unused. Update.

  FIG. 18 explains the details of the input information. The notation of the component ID in the description will be described. The parenthesized numerical value after the component ID indicates “sequential number” that is numbered in reel units for each component ID. For example, when there are three reel parts with the part ID_200 and two reel parts with the part ID_201, the serial numbers are assigned to the individual reels, and for the part ID_200, ID_200 (001), ID_200 (002), ID_200 (003) is numbered, and ID_201 (001) and ID_201 (002) are numbered for the component ID_201. In the present invention, this serial number is assigned according to the order of purchase from the reel maker, and the operation is performed in which the oldest purchase time is used first.

The fixed arrangement information (a) stores the part ID information of the reel parts set in the dual feeder for the fixed arrangement lane. The reason why the lane number 201 is next to the jump number as 203 is that the slot A side of the lane 201 corresponds to the lane 201 and the slot B side of the lane 201 corresponds to the lane 202. It is.
The previous production model arrangement information (b) is the lane arrangement in the bank of the previous production model used for the next production model part arrangement and the part ID information of the reel parts set in the dual feeder. Slot availability information is managed in the same way.

The registered dual feeder information (c) stores information on a registered dual feeder that is managed in a storage shelf or the like with reels set on the dual feeder. In order to manage the in-use and unused states, a state management flag is provided, and a continuous update process is performed in consideration of the state of other mounters.
The remaining reel part number management information (d) stores the remaining part number information in the reel with the part ID (numbering unit). Similarly to the registered dual feeder information, in order to manage in use and unused states, a state management flag is provided, and a continuous update process is performed in consideration of the state of other mounters. In addition, in order to facilitate the search for the reel storage location, shelf number management is performed by component ID (numbering unit).
The next production model NC program (e) stores the component mounting position information of the printed circuit board in the next production model, and all the component IDs, circuit symbols, X coordinate values, Y coordinates mounted on one printed circuit board. Stores value and mounting angle information.

FIG. 19 shows the details of the output information. This information is referred to on a personal computer screen, or is output to paper and manually set up for reference. Information on the part ID of the dual feeder to be set in the bank lane of the next production model is displayed, and the part ID (numbering unit) to be set on the slot A side and the slot B side is displayed with respect to the lane number.
The symbols added to the component ID will be described. “◎” indicates that a reel that is already set in the slot of the dual feeder in the previous production model is an unused reel in the next production model, so that it is removed and a new reel is set. “O” indicates that the slot of the dual feeder is empty in the previous production model and a new reel is set there. “●” indicates that the remaining number of parts on the arranged reel is less than the number used in the next production model, and that the reel replacement work will occur during the mounting work, and that the reel for replacement needs to be prepared in advance. Represents.

  In addition, the fixed feeder dual feeder displays “◯” in the fixed placement column, and the dual feeder is fixed and does not move. When moving the dual feeder by fixing the dual feeder pair, the source lane No. The source lane number is displayed in the column. When a new reel is arranged on the slot A side or the slot B side, the shelf number of the storage shelf in which the new reel is stored is displayed. When a setup operator performs setup work while looking at this next production model layout information, it is possible to smoothly proceed with a series of setup work from reel preparation to each set work by covering the information necessary for setup work. Shortening the setup time can be realized.

  FIG. 20 and FIG. 21 show the part arrangement determination processing flow of the next production model in the present invention. The part arrangement determination process of the present invention is a process executed using a personal computer. First, the next production model NC program is read (S20). Also, the number of users for each part ID is calculated from the information of the next production model NC program.

  Next, the optimum lane arrangement is provisionally determined from the X coordinate value and the Y coordinate value of the next production model NC program (S21). For example, an existing mounter maker or the like, for example, the head unit 8 of the mounter sucks the component 12 on the dual feeder 3 and mounts it on the electronic component mounting position 13 on the printed circuit board 11 to mount the next component. This is done by a component placement decision processing program based on an algorithm that decides the component placement of the lane so as to minimize the total distance to repeat the movement to the picking position for all the components, and the net time is the shortest Determine the component placement of the lane. This is called “optimum lane arrangement” in the present invention. However, setup workability is not taken into consideration in this processing.

  Next, the fixed arrangement information is read as input information (S22). Next, the registered dual feeder information is read as input information (S23). Next, the pre-production model arrangement information is read as input information (S24). Next, the reel component remaining number management information is read (S25). This completes the reading of the input information. Thereafter, the part placement determination process for the next production model is performed.

  First, fixed part determination processing is performed as part placement determination processing (1) (S26). The part ID used in the next production model is compared with the part ID in the fixed arrangement information 124. If the part ID used in the next production model is included in the fixed arrangement information 124, the part is arranged in the next production model arrangement information 127. Perform the process to confirm. The following processing is performed for the part ID used in the next production model whose placement has not been determined by this processing.

  Next, component placement processing for fixing the dual feeder pair (operation No. 2) is performed as component placement determination processing (2) (S27). For dual feeders already set in the lanes in the bank in the previous production model, the parts already set in the dual feeder are not removed by comparison with the optimum lane in the next production model determined in the process of (S21). When the moved lane can be arranged in the optimum lane, or can be arranged in a lane near the optimum lane, a dual feeder is arranged in the lane, and a process for determining in the next production model arrangement information 127 is performed. The following processing is performed for the part ID used in the next production model whose arrangement has not been determined by the processing so far.

  Next, a registered dual feeder component placement process is performed as a component placement determination process (3) (S28). Compare the part ID that is not yet confirmed with the part ID used in the next production model and the part ID in the registered dual feeder information. If there is a registered dual feeder whose status is not used, place the registered dual feeder. To do. In addition, the lane in which the registered dual feeder is set is arranged in the optimum lane or in the vicinity of the optimum lane by comparison with the optimum lane in the next production model determined in the process of (S21), and the next production model arrangement information. A process of confirming within 127 is performed. The following processing is performed for the part ID used in the next production model whose arrangement has not been determined by the processing so far.

  Next, a component placement process for dual feeder empty placement is performed as component placement determination processing (4) (S29). Compare the part ID used for the next production model whose placement is still unconfirmed with the dual feeder placement information in the bank lane of the previous production model and use it in the next production model on the slot A side or slot B side. If the component ID is already set and there is a vacant slot on the opposite side of the set slot, a new reel is arranged. The reels to be newly placed are not used after comparing the number of parts used in the next production model with the remaining part management information and considering the state management (used / unused) of the remaining part management information. The reel is selected and the number of parts used in the next production model <the remaining number of reel parts (numbering unit) is arranged. If the number of parts used in the next production model is less than the number of remaining reel parts (numbering unit), the reel with the number of remaining reel parts (numbering number unit) closest to the number of parts used is placed and the net work is in progress. Since it is known in advance that there will be no parts, an instruction to prepare a replacement reel in advance is given. The lane for setting the dual feeder in which a new reel is set in an empty slot is arranged in the optimum lane or in the vicinity of the optimum lane by comparison with the optimum lane in the next production model determined in the process of (S21). Processing to be confirmed in the production model arrangement information 127 is performed. The following processing is performed for the part ID used in the next production model whose arrangement has not been determined by the processing so far.

  Next, a component placement process of dual feeder unused placement is performed as a component placement determination process (5) (S30). Compare the part ID used for the next production model whose placement is still unconfirmed with the dual feeder placement information in the bank lane of the previous production model and use it in the next production model on the slot A side or slot B side. If the part ID is already set and there is an unused reel in the next production model in the slot opposite to the set slot, the unused reel is removed and a new reel is arranged. Newly placed reel parts are not used after comparing the number of parts used in the next production model with the remaining reel part number management information and considering the status management (used / unused) of the remaining reel part number management information. And the number of reels used in the next production model <the number of remaining reel parts (numbering unit) is arranged. If the number of parts used in the next production model is less than the number of remaining reel parts (numbering unit), the reel with the number of remaining reel parts (numbering number unit) closest to the number of parts used is placed and the net work is in progress. Since it is known in advance that there will be no parts, an instruction to prepare a reel part for replacement in advance is issued. The lane where the unused reel is removed and the dual feeder with the new reel parts set is set to the optimum lane or the vicinity of the optimum lane according to the comparison with the optimum lane in the next production model temporarily determined in the process of (S21). And the process of confirming in the next production model arrangement information 127 is performed. The following processing is performed for the part ID used in the next production model whose arrangement has not been determined by the processing so far.

  Next, component placement processing for new component placement is performed as component placement determination processing (6) (S31). A new reel is arranged for an empty dual feeder in which the reel parts are not set on both the slot A side and the slot B side with respect to a part ID that has not yet been arranged with the part ID used in the next production model. . The reels to be newly placed are not used after comparing the number of parts used in the next production model with the remaining part management information and considering the state management (used / unused) of the remaining part management information. The reel is selected and the number of parts used in the next production model <the remaining number of reel parts (numbering unit) is arranged. If the number of parts used in the next production model is less than the number of reels remaining (reel number), the reel with the remaining number of parts (number) is closest to the number of parts used, and the part is being used during the net work. Since it is known in advance that there will be no more, an instruction to prepare replacement reel parts in advance is issued. The lane where the unused reel parts are removed and the dual feeder with the new reel parts set is set to the optimal lane or the optimal lane by comparing with the optimal lane in the next production model temporarily determined in the process of (S21). Arrangement is performed in the vicinity, and processing is confirmed within the next production model arrangement information 127. This completes the part placement determination process for the next production model.

Next, the next production model arrangement information described with reference to FIG. 19 is generated and output based on the part arrangement determination information (S32).
Next, the state management information (used / unused flag) of the registered dual feeder information is updated based on the component arrangement determination information (usage reservation) (S33). This is a process that is performed in order to prevent the registered dual feeder scheduled to be used in this line from being used in another line when the same next production model arrangement determination process is performed in another line.
Next, the status management information (used / unused flag) in the reel component remaining number management information is updated based on the component arrangement determination information (usage reservation) (S34). This is a process that is performed in order to prevent the reel parts (numbering unit) scheduled to be used in this line from being used in other lines when the same next production model placement determination process is performed in other lines. is there.
Next, based on the next production model arrangement information output in (S32), the operator manually performs setup work (S35). The setup work time performed based on the next production model arrangement information is the shortest work time.

  Next, the mounter performs net work automatically (S36). The net work time is not the shortest net time because there is a difference in the lane arrangement compared to the optimum lane arrangement determined in (S21), but in the component arrangement process, the net work time is arranged in the optimal lane or in the vicinity of the optimal lane. Therefore, the effect of increasing the net work time is minimal. In addition, the component placement process is performed in consideration of the number of parts used in the next production model and the remaining number of reel parts, so the mounter stops due to frequent parts replacement work due to parts running out during the reel part mounting process. Time increase can be suppressed. When the net work is completed, the bank and dual feeder are diverted to the production model one after another, and the bank is manually removed from the mounter.

Next, a process of updating the remaining part number in the reel part remaining number management information is performed (S37). The number of used parts consumed in the net work is subtracted from the number of remaining parts in the reel part remaining number management information and updated.
Next, the setup work for the production models is performed manually (S38). In this process, the part placement determination process for the next production model is carried out in advance using the part placement for the next production model, and the setup work for the production model is performed one after another based on the part placement decision information. Again, the setup work time is the shortest work time.
Next, processing for updating the status management (used / unused flag) of the registered dual feeder information is performed for the registered dual feeder that has become unused due to the setup of the production model one after another (usage flag release) (S39).
Next, processing for updating the status management (used / unused flag) of the reel component remaining number management information is performed (removal of used flag) for reel components that have become unused due to the setup of production models one after another (S40).
As described above, the above processing flow is repeatedly performed.

  22, 23, and 24 show the details of the part placement determination process flow of the next production model in the present invention, and will be described using examples. The part arrangement determination process of the present invention is a process executed using a personal computer. First, the next production model NC program is read (S60). Based on the read information of the next production model NC program, the number of users for each part ID is calculated. Next, the optimum lane arrangement is provisionally determined from the X coordinate value and the Y coordinate value of the next production model NC program (S61). This is performed by the component placement determination process in the conventional mounter, and determines the component placement in the lane that has the shortest net time. If the installation work of the next production model is carried out with this component arrangement, the net work time will be the shortest. However, the setup work time is usually long because the setup workability is not considered.

Next, the fixed arrangement information is read as input information (S62). Next, the registered dual feeder information is read as input information (S63). Preferentially arrange registered dual feeders whose status is unused.
Next, the pre-production model arrangement information is read as input information (S64). Next, the reel component remaining number management information is read (S65). The reel part remaining number management information is managed for all reel parts used in the mounter. Preferentially arrange reel components that are not in use, reels with a sufficient number of remaining components for the number of users of the next production model, and reels with a small number (= old purchase time). This completes the reading of the input information. Thereafter, the part placement determination process for the next production model is performed.

  First, fixed part determination processing is performed as part placement determination processing (1) (S66). Whereas the reel part with ID_202 is used in the next production model, there is a reel part with ID_202 in the fixed arrangement information lane 203, so ID_202 is arranged in the lane 203 and confirmed.

  Next, a component placement process fixed to the dual feeder pair is performed as a component placement determination process (2) (S67). While the reel part of ID_1 is used in the next production model, the reel part of ID_1 is in the lane 101 of the previous production model, and the optimal lane arrangement of ID_1 is the lane 105. Since the lane is an empty lane, the dual feeder of lane 101 is moved to the lane 105 as it is (fixed as a pair) and the arrangement is fixed. In addition, the reel part of ID_3 is used in the next production model, whereas the reel part of ID_3 is in the lane 103 of the previous production model, and the optimal lane of ID_3 is the lane 103. Therefore, the dual feeder of the lane 103 is Do not move, place (pair fixed) as it is and confirm.

  Next, a registered dual feeder component placement process is performed as a component placement determination process (3) (S68). While the reel parts of ID_101 and ID_102 are used in the next production model, the registered dual feeder No. in the registered dual feeder information is used. 1 has reel parts of ID_101 and ID_102 and is in an unused state, so this registered dual feeder is arranged. As for the lanes to be arranged, the ID_101 is the lane 101 and the ID_102 is the lane 103 from the optimum lane arrangement. The lane 103 has already been arranged by the component arrangement determination process (2). Dual feeder No. registered in Place 1 and confirm.

  Next, a component placement process for dual feeder empty placement is performed as component placement determination processing (4) (S69). Whereas the next production model uses the ID_12 reel part, the optimum lane of ID_12 is the lane 101. Since the lane 101 has already been determined in the component placement determination process (3), it is desirable to place the lane 101 in a nearby lane 103. The arrangement of the lane 103 has already been determined by the component arrangement determination process (2). However, since the slot B side is empty, ID_12 is arranged and determined as a new reel part on the slot B side of the lane 103 dual feeder. A new reel part with ID_12 to be arranged is selected by comparing the remaining reel part number management information with the number of users in the next production model. There are ID_12 (002) = 10 and ID_12 (003) = 100 parts remaining in ID_12 of the reel part remaining number management information, and the status is unused, but the number of ID_12 used in the next production model Since ID = 15 (003), the number of users <the remaining number of parts is set.

  Next, component placement processing for dual feeder unused placement is performed as component placement determination processing (5) (S70). Whereas the next production model uses the ID_103 reel part, the optimal lane of ID_103 is the lane 107. Since the lane 107 is an empty lane, the dual feeders cannot be placed unused. There is a lane 105 in the vicinity of the lane 107, and the ID_2 reel component that has already been arranged on the slot B side of the dual feeder is an unused component in the next production model, so ID_103 is on the slot B side of the lane 105 dual feeder. Place and confirm as a new reel part. The new reel part with ID_103 to be arranged is selected by comparing the remaining reel part number management information with the number of users in the next production model. Since there are ID_103 (007) = 40 and ID_103 (008) = 100 parts remaining as ID_103 in the reel part remaining number management information, the number of ID_103 used in the next production model is 60. I want to select ID_103 (008) where the number of parts <the number of remaining parts, but I cannot select because the state of ID_103 (008) is in use. In that case, ID_103 (007) is selected so that the number of users> the number of remaining parts, and it can be determined in advance that there will be no parts during the net work in advance, so it is necessary to prepare spare reel parts for replacement in advance. This is instructed by the model arrangement information.

Next, component placement processing for new component placement is performed as component placement determination processing (6) (S71). In the next production model, reel parts ID_20 and ID_150 are used, whereas the optimum lane of ID_20 and ID_150 is lane 203. Since the arrangement of the lane 203 has already been determined by the component arrangement determination process (1), the lane 203 is arranged in the neighboring lane 107. Since the lane 107 is an empty lane in the previous production model, a new reel part is arranged and determined for an empty dual feeder in which no reel part is set on both the slot A side and the slot B side. The new reel parts ID_20 and ID_150 to be arranged are selected by comparing the remaining reel part number management information and the number of users in the next production model. The number of remaining parts of ID_20 in the reel part remaining number management information is ID_20 (001) = 500, and the number of ID_20 in the next production model is 30, so that the number of users <the remaining number of parts ID_20 Select (001). There are ID_150 (003) = 100 and ID_150 (004) = 200 parts remaining in ID_150 of the reel part remaining number management information, and ID_150 is 90 in the next production model, so ID_150 For both (003) and ID_150 (004), the number of users is less than the remaining number of parts, and either may be selected, but here, the reel part of ID_150 (003) whose purchase time is old is selected.
ID_203 arranged on the lane 203 dual feeder slot B side is a part that is not used in the next production model, but is not removed. This completes the part placement determination process for the next production model.

Next, the next production model arrangement information of FIG. 19 is generated and output based on the part arrangement determination information (S72).
Next, based on the component placement determination information, processing for updating the state management information (used / unused flag) of the registered dual feeder information is performed (usage reservation) (S73).
Next, a process of updating the state management information (used / unused flag) of the reel component remaining number management information based on the component placement determination information is performed (usage reservation) (S74).

Next, based on the next production model arrangement information output in (S72), the operator manually performs setup work (S75). The setup work time performed based on the next production model arrangement information is the shortest work time.
Next, the net work by the mounter is performed (S76). The net work time is not the shortest net time because there is a difference in the lane arrangement as compared with the provisional lane optimum arrangement (S71), but it is arranged in the optimum lane or in the vicinity of the optimum lane in the component arrangement process. Therefore, the effect of the increase in net work time is minimal. In addition, since the component placement processing is performed in consideration of the number of component users and the number of remaining components in the reel, an increase in mounter stop time due to frequent component replacement work can be suppressed. When the net work is completed, remove the bank and dual feeder from the mounter one after another in order to use the bank and dual feeder.

Next, a process of updating the remaining part number in the reel part remaining number management information is performed (S77). The number of parts consumed in the net work is subtracted from the number of remaining parts in the reel part remaining number management information and updated.
Next, the setup work for the production models is performed manually (S78). In this process, the part placement determination process for the next production model is carried out in advance using the part placement for the next production model, and the production model is set up manually one after another based on the part placement decision information. Again, the setup work time is the shortest work time.

Next, for registered dual feeders that have become unused due to the setup of production models, the status management information (used / unused flag) of the registered dual feeder information is updated (used flag cancellation) (S79).
Next, a process of updating the state management information (used / unused flag) of the remaining number of reel parts management information is performed for the reel parts that have become unused due to the set-up of production models (use flag release) (S80).
As described above, the above processing flow is repeatedly performed.

  FIGS. 25 and 26 are obtained by adding a determination process (S99 / S101) for enabling or disabling the process before the component placement determination process to the process flow of FIGS. 20 and 21 of the first embodiment. is there. In the example of FIGS. 25 and 26, the determination processing (S99 / S101) is added before the component placement determination processing (4) and the component placement determination processing (5), but before the other component placement determination processing. A determination process may be added to.

In the case of FIGS. 25 and 26, the determination process is added by using the dual feeder used in the previous production model for the setup work determined by the part placement determination process (4) and the part placement determination process (5). In order to work, the work cannot be started unless the net work of the previous production model is completed. If there are a large number of dual feeders and reels, the component placement determination process is performed without performing the setup work determined by the part placement determination process (4) and the part placement determination process (5) when it is desired to perform the setup work in advance. If the setup work determined in (6) is performed in advance, the setup work time may be the shortest. In other words, a dual feeder with a new reel set in advance during the net production of the previous production model is prepared in advance, and when the net production of the previous production model is completed, the setup work can be performed only by moving and setting the dual feeder in the bank lane. Can be completed.
By adding a judgment process before the part placement determination process, the degree of freedom of the process can be increased, and an optimal part placement is output as appropriate according to the operation status of the mounter to which the part placement determination process of the present invention is applied. It becomes possible to do.
