Description

  The present invention relates to a setup support method for a mounter that mounts components on a printed circuit board.

  2. Description of the Related Art As a mounting machine for mounting electronic components on a printed circuit board, there is known a mounting machine that transports and mounts electronic components such as ICs on a printed circuit board with a suction head from a plurality of mounted component supply devices.

  Regarding the arrangement of the component supply device in such a mounting machine, various optimization methods for improving mounting efficiency have been proposed (see Patent Document 1 below).

  FIG. 3 is a functional explanatory diagram of a component supply unit of the mounting machine. As shown in the figure, in the component supply unit 31 to which the tape feeder 35 and the like are attached, a plurality of feeder attachment portions 332 are provided on the feeder plate 33, and a feeder 35 such as a tape feeder can be attached to each of them.

  If each feeder 35 is a tape feeder, a reel 353 around which a tape storing small pieces of components such as ICs and transistors is stored at predetermined intervals is mounted, and the tape is intermittently fed out from the reel 353. Thus, the parts stored on the tape can be supplied sequentially. Each feeder 35 or the like constitutes a component supply device.

  Each feeder 35 is provided with a storage medium 351 in which feeder ID information that can identify each feeder 35 is stored. The feeder 35 is attached to each feeder attachment portion 332 by a feeder ID reading portion 331 provided on the feeder plate 33. The feeder ID of the feeder 35 is read.

  Further, a recording medium 352 made of a bar code seal or the like on which feeder ID information is recorded is also attached to the side surface of each feeder 35, and this bar code seal is mounted before the feeder 35 is attached to the feeder plate 33. By reading with a barcode reader 13 or the like connected to the machine 10, the feeder ID or the like can be known.

  The tray-type component supply unit 32 includes a magazine 34 that accommodates the pallet 36, and the pallet 36 can be attached in a stacked manner.

  A component tray 363 containing an electronic component C such as an IC is placed on each pallet 36, and when each pallet 36 is pulled out from the magazine 34, it is appropriately picked up by each head 41 of the head unit 40. Yes. Each pallet 36 constitutes a component supply device.

  Each pallet 36 is provided with a storage medium 361 in which pallet ID information that can be identified is stored. The pallet 36 is attached to each storage stage of the magazine 34 by a pallet ID reading unit 341 provided in the magazine 34. The pallet ID of the pallet 36 is read.

  In addition, a recording medium 362 made of a bar code seal or the like on which pallet ID information is recorded is also attached to the front side of each pallet 36. This bar code seal is mounted before each pallet 36 is accommodated in the magazine 34. By reading with a barcode reader 13 or the like connected to the machine 10, the pallet ID or the like can be known.

  Since the types of parts supplied by each feeder 35 and pallet 36 depend on the tape 353 and tray 363 mounted, when the tape 353 or tray 363 is mounted on the feeder 35 or pallet 36, the feeder ID, pallet ID, and component information Are stored in advance in the component identification information database.

  When the feeder ID or pallet ID is read by the feeder ID reading unit 331, the pallet ID reading unit 341, the bar code reader 13 or the like, the control device (controller) 99 of the mounting machine 10 makes an inquiry to the component identification information database to inquire the feeder. It is possible to obtain part information about parts supplied by 35 and the pallet 36.

  Such a component identification information database may be provided in each mounting machine 10, or may be provided in a higher-level computer or the like capable of transmitting and receiving information via the communication line of the mounting line 90.

  The feeder ID reading unit 331 and the pallet ID reading unit 341 of the mounting machine 10 function as a current arrangement acquisition unit that acquires the current arrangement of the component supply devices such as the feeder 35 and the pallet 36 that are attached.

  In the mounting line 90 provided with a plurality of such mounting machines 10..., After the cream solder is printed by the printing machine 92 on the board carried in from the board carry-in machine 91, the electronic components are placed by the plurality of mounting machines 10. Although mounting is performed, a mounting operation for mounting components on each board to be produced is shared by a plurality of mounting machines 10... So that the board can be efficiently produced.

  In the mounting line 90 of this embodiment, a mounting operation for mounting various components on a production target board is assigned to a component supply apparatus that is currently attached to any mounting machine of the mounting line 90. Of the necessary components, the components that are not attached to any mounting machine on the mounting line 90 are notified to the operator and prompted to attach to any mounting machine on the mounting line 90 to respond. ing.

  According to such a setup method, if a component supply device that supplies necessary components is attached to any of the mounting machines on the mounting line 90, the operator can attach, remove, and move such a component supply device. Since the accompanying work can be reduced, the setup work can be facilitated.

  For example, during actual setup work, a component supply device for the board that was produced immediately before is already attached to each mounting machine, so using this can provide excellent setup workability. it can.

  However, if the mounting work to each mounting machine is assigned according to the component supplying apparatus currently attached to each mounting machine in this way, the type of the component supplying apparatus attached to each mounting machine and the production target Depending on the combination of board types, there is a possibility that the load of the mounting work performed by each mounting machine may not be distributed in a well-balanced manner. In particular, if a facility that causes a bottleneck in which the mounting work time is longer than other mounting machines, such as when the mounting work is concentrated on a specific mounting machine, the production efficiency of the entire mounting line may be reduced.

  In addition, for each mounting machine, depending on the combination of the arrangement of the component supply device attached and the mounting work assigned to the mounting machine, the head moving distance in each mounting work may become longer, There is a possibility that high production efficiency may not be obtained because there are few opportunities for simultaneous adsorption of parts.

  Therefore, in the present invention, the estimated production time required for board production in the current arrangement of the component supply device is calculated, and it is determined whether or not this satisfies a predetermined allowable production efficiency standard. It is possible to determine whether or not it is appropriate to perform substrate production with this arrangement.

  In this embodiment, the estimated production time is for a mounting line including a plurality of mounting machines, and therefore an estimated cycle time C that represents the production efficiency of the board as the entire mounting line is employed. That is, it is a time interval at which a production completion board is discharged as a mounting line. Specifically, the estimated production time of the mounting machine that requires the longest production time among the estimated production times for each mounting machine is the estimated production time for the entire mounting line.

  Estimated production time for each mounting machine is determined by an optimization method using the optimization method to determine the specific execution procedure of the production operation on condition that the mounting work assigned to each mounting machine is executed with the current arrangement of component supply devices. It is calculated as the time required for the optimized execution procedure. In this execution procedure, when there are multiple parts supply devices that supply the same type of component, which component supply device is used, which head is used, whether simultaneous suction is possible, and confirmation and inspection of sucked components This includes setting which camera to use and setting the order of each mounting operation. As the optimization method, any known method can be adopted.

  In addition, when the number of production is small, the sum of the estimated production time for each mounting machine may be used so that the time from when each board is put into the mounting line until it is completed is reflected.

  On the other hand, the allowable production efficiency standard is a standard for determining whether the estimated production time is good or not. In this embodiment, the component supply device is ideally distributed to each mounting machine of the mounting line, and each mounting machine is Is set based on the production time (hereinafter referred to as the ideal production time) in the state of being arranged at the ideal mounting position (hereinafter referred to as the ideal arrangement including distribution to each mounting machine).

  The ideal production time for a component supply device is the allocation setting of the mounting work to each mounting machine, the distribution of the component supply device to each mounting machine, the placement of the component supply device at each mounting position of each mounting machine, and the production operation A specific execution procedure is obtained by an optimization method, and is calculated from the time required for the optimized execution procedure. The ideal arrangement of the component supply device is obtained as the arrangement of the component supply device when an ideal production time is obtained. As the optimization method, any known method can be adopted. With respect to the ideal production time, the ideal cycle time C ′ is adopted because the present embodiment targets a mounting line including a plurality of mounting machines.

  Further, in this embodiment, in order to more appropriately determine whether or not to start production with the current arrangement, the allowable production efficiency standard is added to the ideal production time, and the component supply apparatus is changed from the current arrangement. It is set in consideration of the estimated setup time d required to shift to the ideal arrangement (perform setup change).

  For example, in this embodiment, the estimated setup time d is calculated from the difference between the current arrangement of the component supply devices and the ideal arrangement, the number of component supply devices that need to be removed, the number of component supply devices that need to be newly installed, Calculate the number of component supply devices that need to be moved in one mounting machine, and the number of component supply devices that need to be moved to other mounting machines, and multiply these by the standard work time set for each type of work. Calculated by summing.

  Furthermore, in this embodiment, in order to be able to compare the estimated setup time for shifting to such an ideal arrangement in the same dimension as the production time per one substrate (cycle time), the allowable production efficiency standard is It is set in consideration of the planned production number n of the production target substrate.

  Specifically, the net production time from the start of production to the completion of production is obtained by obtaining the product of the ideal production time (ideal cycle time) C ′ per substrate and the planned production number n, and the changeover is made to this. The estimated total time C ′ × n + d required for shifting from the current arrangement to the ideal arrangement and completing the production of the expected number of substrates can be obtained by adding the estimated setup time d required for the above.

  On the other hand, as the product of the estimated production time (estimated cycle time) C per substrate in the current arrangement and the planned production number n, the estimated total time C required to start production and complete production with the current arrangement. Xn is required.

  By comparing the two expected total times calculated in this way, the current arrangement is quantitatively compared between the case where the current arrangement is produced and the case where the production is performed after the setup work to the ideal arrangement. The production efficiency in can be judged more accurately.

  As a final criterion, when the difference between the two is within a preset allowable time difference (eg, within 30 minutes), the ratio between the two is within a preset allowable ratio (eg, 10%). Or a combination judgment of satisfying both or satisfying at least one of them.

  This final standard can be set as appropriate in consideration of the labor cost of the operator necessary for the setup change, the risk of occurrence of setup errors, and the like.

  As a result of such final determination, if it is determined that it is appropriate to start production with the current arrangement of the component supply devices, production permission is given to each mounting machine and production can be started. It becomes a state.

  On the other hand, if it is determined that it is not appropriate to start production with the current arrangement of the component supply devices, the operator is notified of this. As a result, it is possible to prevent a situation in which the production is started with a low production efficiency below a predetermined standard and the production plan goes beyond a predictable level.

In addition, when the production with the current arrangement of the parts supply apparatus is not appropriate, a proposal for changing the arrangement of the parts supply apparatus that can improve the production efficiency is created and notified to the operator as a setup change instruction. It has become.
The contents of the setup change instruction do not necessarily change the current arrangement to the ideal arrangement.

  As the contents of the layout change by this setup change instruction, for example, in each mounting machine, several component supply devices are moved so as to be adjacent to each other so as to increase the chance of simultaneous suction of components, or the mounting position on the board For example, the component supply device may be moved to a mounting position close to.

  Also, from the viewpoint of improving the production efficiency of the entire mounting line, for example, the load balance of each mounting machine is judged, for example, the mounting work allocated to the mounting machine with the maximum load is mounted with a low load. A setup change operation for moving the component supply device used for the mounting operation between the mounting machines can be set so as to be moved to the mounting machine.

  When the placement of the component supply device is changed based on the setup change instruction in this way, for the mounting machine for which the setup change has been made, for each assigned mounting operation, the type of component to be mounted and the installation of the component supply device to be used The production program including each data such as the position, the mounting coordinate position on the substrate, and the order of performing each mounting operation is changed.

  In this embodiment, calculation of the above estimated production time, determination of whether or not the allowable production efficiency standard is satisfied, and creation of a layout change plan, etc. are performed with the control device 99 of each mounting machine in the mounting line 90 and a communication line. It is composed of a personal computer capable of transmitting and receiving information, and is performed by a management computer that comprehensively manages the operation of each mounting machine on the mounting line 90.

  FIG. 4 is an explanatory diagram conceptually showing transmission / reception of information between each mounting machine. As shown in the figure, each mounter and the management computer (PC) are connected via a network and can send and receive information.

  Each mounting machine uses a management computer (PC) that supervises the setup work through the network of the mounting line, using the current arrangement of the component supply device attached to itself and the assigned mounting work as its own equipment setup information. Send to. The communication means included in the control device 99 of each mounting machine functions as a transmitting means for transmitting the current arrangement of the component supply devices attached to each mounting machine to the outside.

  The management computer (PC) that receives the setup information from each mounting machine calculates the estimated production time based on the setup information of each mounting machine, and whether or not the current arrangement is maintained based on whether or not this satisfies the allowable production efficiency standard. Judge whether or not to start production. This management computer functions as calculation means for calculating the estimated production time, and further as determination means for determining whether this satisfies the allowable production efficiency standard.

  If the production start is appropriate as a result of the determination on the suitability of the production start, the management computer permits the production start to each mounting machine on the mounting line.

  On the other hand, if it is inappropriate, the management computer (PC) issues a display command for displaying the fact on the display device (monitor screen) 98 to each mounter so as to notify the operator of that fact. In addition, the management computer creates a component supply device layout change plan for improving the production efficiency, and issues a layout change instruction (setup change instruction) to the display device 98 for the mounter to be subjected to the layout change. Issue a display command to be displayed. The display device 98 of each mounting machine functions as a notification unit.

  The management computer optimizes and creates a production program in each mounting machine in a state where the arrangement of the component supply devices has been changed, and transmits this to each mounting machine. Each mounting machine receives this and stores it in the respective storage means, so that production can be performed in the state after the setup change.

  FIG. 5 is a flowchart showing the overall flow of board production in this mounting line. As shown in the figure, in the production of a new type of board, first as production preparation (step S1), a production program for the board to be produced is called in each mounting machine (step S2), and the called production is performed. Based on the program, the conveyor width of each mounting machine, the height position of the substrate support plate, and the like are automatically set (step S3).

  Subsequently, as a so-called setup operation, a component supply device for supplying electronic components necessary for a substrate to be produced and an electronic substrate to be mounted are prepared by an operator (step S4), and if ready, operation is started (step S5). ) And production is performed (step S6).

  During such production, electronic parts and electronic substrates are appropriately supplied (step S7), and when the planned production number is produced, the production is terminated (step S8), and the production returns to the next substrate.

  FIG. 6 is a flowchart showing the procedure of the setup work in this mounting line. This setup operation is performed in step S4 of FIG.

  As described above, in this embodiment, first, a mounting operation is assigned to each mounting machine according to the current arrangement of the component supply devices, and the component supply device that supplies the missing components is attached.

  As shown in the figure, when the mounting (setup) of electronic components to be prepared by the operator is completed in each mounting machine (step S10), the management computer allocates and assigns the current component supply device from each mounting machine. Production program elements such as component information and assembly coordinates used for the mounting operation are collected (step S12).

  Then, the management computer performs a setup check including the presence / absence determination of a missing component by the component supply device attached to each mounting machine (step S14). If the setup check is not established (NO in step S14), the missing component is detected. A setup correction instruction is issued to each mounting machine for instructing the mounting of the component supply apparatus for supplying the component (step S16). Each mounting machine notifies the operator of a setup correction instruction and prompts the operator to correct the setup.

  If the setup check is established (YES in step S14), it is possible to produce with the component supply device currently arranged on each mounting machine in the mounting line. Thus, a specific execution procedure (production program) of the production operation is obtained by the optimization method (step S18), and the estimated production time in the current arrangement is calculated (step S20).

  Next, an allowable production efficiency standard for the substrate to be produced is obtained. At this time, it is determined whether or not the predicted production time data in the ideal state in which the component supply device is ideally arranged has been calculated in the past (step S22), and if it has been calculated (YES in step S22), the ideal state The ideal production time predicted in advance is called (step S24). This is because the ideal production time in the mounting line for each production target board does not change if the configuration of the mounting machine is constant regardless of the current arrangement of the component supply devices.

  If there is no predicted production time data calculated in advance (NO in step S22), the optimization calculation of the production program in the ideal state is performed (step S26), and the production time in the ideal state (ideal production time) is calculated. (Step S28). In this optimization calculation, the ideal arrangement is obtained without fixing the arrangement of the component supply devices, and the production time under the ideal arrangement is calculated.

  If the ideal production time is obtained, the component supply device is moved from the current component supply device arrangement, and the setup time (estimated setup time) required to realize this ideal state (ideal arrangement) is calculated (step S30).

  Thus, if the estimated production time in the current arrangement, the ideal production time in the ideal arrangement, and the estimated setup time required to move from the current arrangement to the ideal arrangement are set, the values are set based on the ideal production time and the estimated setup time. It is determined whether the estimated production time satisfies the allowable production efficiency standard (step S32).

  As a result of this determination, if the standard is satisfied (YES in step S32), even if production is started with the current arrangement, a certain production efficiency is ensured, so that a production permission is issued (step S34).

  On the other hand, if the criterion is not satisfied as a result of this determination (NO in step S32), an abnormality report is issued (step S36), and the operator is forced to produce the product in the current arrangement that is concerned about the production efficiency. Whether or not to start. This abnormality report or the like is performed in each mounting machine by a display command from the management computer, and is displayed to the operator by being displayed on a monitor or the like of each mounting machine.

  FIG. 7 is an example of an abnormality report screen when the production efficiency in the current arrangement does not satisfy the standard. As shown in the figure, when the production efficiency does not meet the standard, the degree of not satisfying the standard is also notified. Specifically, production starts with the current layout (current setup state), with a production time of 25 minutes and 00 seconds expected to be required when producing 50 boards to be produced after shifting to the ideal state. A production time of 40 minutes and 24 seconds, which is expected to be required, and a ratio of 162% in the current setup state when the transition to the ideal state is 100% are displayed.

  In addition, on this abnormality report screen, it is possible to select to force the start of production with the current arrangement at the operator's discretion.

  If there is an input from the operator to start forced production (YES in step S38) with respect to the choice of whether to start forced production (step S38), parts that are necessary for production although there is concern about production efficiency Since they are ready and can be produced, a production permission is given (step S34).

  On the other hand, if an input indicating that forced production is not to be performed is made (NO in step S38), a setup correction instruction for increasing production efficiency is issued to the operator (step S16). This setup correction instruction is issued in each mounting machine by a display command from the management computer, and is displayed on each mounting machine on a monitor or the like to be notified to the operator. At this time, a production program (optimized production program) in a state after the setup correction is also transmitted to each mounting machine).

  FIG. 8 is a screen example of a setup correction instruction. FIG. 5A is issued to the mounting machine A, for example, and is displayed on the display device (monitor) of the mounting machine A. FIG. 6B is issued to the mounting machine B, for example, and is displayed on the display device (monitor) of the mounting machine B. Specifically, in the mounting machine A in FIG. 4A, the setup state is OK except for the lower right of the four component supply units included in the mounting machine. The symbol indicating the mounting position F21 emits red light, for example, and the parts with the part name PARTS013 are supplied as shown in the work instruction column as “part removal: PARTS013 (F21)”. An operation instruction for removing a component supply device (8 mm tape feeder) is issued. Further, in the mounting machine B of FIG. 5B, the setup state is OK except for the lower right part of the four parts supply units of the mounting machine, but the lower right part supply apparatus and the mounting position F25. A component supply device that supplies a part having a part name PARTS013 to the mounting position F25 as indicated by a symbol indicating red, for example, as indicated by “part mounting: PARTS013 → F25” in the work instruction column. A work instruction for attaching (tape feeder of 8 mm tape) is issued.

  Since each of these setup correction instructions is given by the display device of the mounting machine itself to be operated, the operator can easily grasp the contents of the setup change work.

  As described above, if the setup change is performed, the process returns to step S10, the production efficiency in the arrangement of the component supply devices after the setup change is evaluated, and the production is started if a certain production efficiency is ensured.

  The present invention has been described based on one embodiment. However, the present invention is not limited to the above-described configuration, and may be appropriately changed as follows.

  For example, in the above embodiment, a tape feeder and a pallet are used as an example of the component supply device, but the component supply device is not limited thereto, and a bulk feeder, a feeder configured to supply a wafer on which a bare chip is mounted, etc. Other types of component supply devices may be used.

  In the above embodiment, a head for mounting a component on a substrate as a mounting machine can move in a linear uniaxial direction, can move freely in two directions on a plane, or can move on a circumference. It may be a thing. In addition, although the mounting machine is an example that mounts a component supply device, the component of the supply device is mounted on the board even if it is connected to an external component supply device or just placed in the vicinity. Anything that can be mounted is acceptable. The mounting line according to the present invention can be formed by combining one or more of these various mounting machines.

  In the above embodiment, the management computer that performs overall control of each facility (mounting machine) on the mounting line functions as a means for calculating the estimated production time and a means for determining whether the allowable production efficiency standard is satisfied. The mounting unit control means may perform these functions.

  Further, each facility (mounting machine) constituting the mounting line may calculate an estimated production time for the own facility and determine whether or not the allowable production efficiency standard is satisfied.

  In the above embodiment, a mounting line including a plurality of mounting machines (equipment) is targeted. However, the present invention may be applied to a single mounting machine. In this case, the control means including a computer provided in the mounting machine may function as the above-described calculation means and determination means.

  In the above-described embodiment, the ideal production time C ′ and the estimated production time C are times from when the board is carried in until various operations related to mounting are performed and the board is carried out. In the case where the carry-in to the machine and the carry-out from the upstream mounting machine are performed in synchronization, this time may be a time from when the board is carried in until various operations related to the mounting are performed.

  Also, the estimated total time required to complete the production of the expected number of substrates by shifting from the current expected arrangement to the ideal arrangement is obtained using C ′ × n + d. There may be a case where not all of the plurality of mounting machines perform the mounting work in the portion where the board is carried out. In this case, C ′ × (n + number of mounting machines−1) + d is used. In this case, when carrying in to the downstream mounting machine and carrying out from the upstream mounting machine are performed synchronously, C ′ × (n + number of mounting machines−1) + d + loading time is used.

  Similarly, the same applies to the estimated total time related to the estimated production time C. Instead of C × n, C × (n + number of mounting machines−1) is further transferred from the downstream mounting machine to the upstream mounting machine. When carrying out in synchronism with unloading, C ′ × (n + number of mounting machines−1) + d + loading time is obtained.

  Furthermore, the mounting time is considered only for the parts related to a plurality of mounting machines. However, in addition to the plurality of mounting machines, the board loading machine 91, the printing machine 92, the inspection machine 93, the reflow furnace 94 and the board unloading machine are included in the mounting line. There are various other facilities such as 95, and there is a production time in each facility required for the substrate to receive work and pass. When the production times of these facilities do not match, the production time (cycle time) of each facility is made to coincide with the longest production time, so that it is not necessary to arrange a buffer for storing substrates. If the production time (cycle time) on the equipment side other than the mounting machine and the production time (cycle time) on the mounting machine side do not match, the production time (cycle time) of both is made to match. In other words, setup support is provided so as to minimize the production time (cycle time) on the mounting machine side, and the shortest production time (cycle time) on the mounting machine side and the production time (cycle time) on the equipment side other than the mounting machine. If the production time (cycle time) on the shortest mounting machine side is longer, the production time (cycle time) on the mounting machine side is matched, and the production time on the shortest mounting machine side ( If the cycle time is shorter, the setup is changed by rearranging the component supply equipment so long as the production time on the mounting machine side (cycle time) does not exceed the production time on the equipment side other than the mounting machine (cycle time). In order to shorten the time, a new arrangement of the component supply device is required. As a result, the production efficiency of the entire mounting line can be increased and the setup workability can be improved.
