Description

  The present invention relates to a feeder attachment / detachment timing guide method and a production line management system for guiding an operator on the removal / attachment timing of a feeder of an electronic component mounting machine.

  FIG. 6 is a perspective view of the electronic component mounting machine. As shown in FIG. 6, a device pallet 101 is arranged on the electronic component mounting machine 100. In the device pallet 101, a large number of tape feeders 102 are arranged in two upper and lower stages. The tape feeder 102 includes a tape 103. A large number of electronic components are arranged on the tape 103 at predetermined intervals in the longitudinal direction. On the single tape 103, electronic components of the same component type are arranged. Electronic components of different component types are arranged on different tapes 103. The electronic component mounting machine 100 mounts electronic components on a board according to a preset production program.

  When the substrate type of the substrate to be produced is switched, an unnecessary electronic component and a necessary electronic component are generated. That is, an electronic component that needs to be replaced is generated. FIG. 7 is a perspective view of the pallet exchange cart. As shown in FIG. 7, a device pallet 101 is mounted on the pallet exchange cart 104. Conventionally, a large number of electronic components that need to be replaced, that is, the tape feeder 102, are collectively replaced. That is, a large number of tape feeders 102 that are no longer necessary due to the switching of the substrate type of the substrate are placed on the pallet exchange carriage 104 together with the device pallet 101 and removed from the electronic component mounting machine 100. In addition, a large number of tape feeders 102 that have become necessary due to the switching of the substrates are mounted on the pallet exchanging carriage 104 together with the device pallet 101 and attached to the electronic component mounting machine 100.

  However, even if the tape feeder 102 is no longer necessary due to the switching of the substrate type, it can be left as it is in the electronic component mounting machine 100 as long as the arrangement of the tape feeder 102 after the switching is not disturbed.

  In view of this point, Patent Document 1 compares the types and arrangements of the tape feeders 102 before and after the switching of the substrate type. Even if the tape feeder 102 is no longer necessary due to the switching of the substrate type, the tape feeder 102 after the switching is changed. A feeder replacement method for leaving the electronic component mounting machine 100 as it is if it is not in the arrangement is disclosed. According to the feeder replacement method described in the document, it is possible to reduce an operator's work load accompanying switching of the substrate type. In addition, it is possible to quickly cope with the switching of the substrate type.

  Also in Patent Document 2, as in Patent Document 1, component arrangement information before switching board types (component supply unit arrangement number information and component information) is compared with component arrangement information after switching board types. A setup change information creation method for creating setup change information is disclosed.

  According to the methods of Patent Documents 1 and 2, the number of feeders to be removed can be reduced when the substrate type is switched. However, as long as there are electronic components required by switching the substrate type, in other words, as long as there are feeders to be attached, the production line must be temporarily stopped. For this reason, the operation rate of a production line falls.

  In particular, in recent years, many kinds of substrates (many substrate types) are produced in small quantities (the number of produced substrates of the same substrate type is small) on the same production line. In this case, if the production line is stopped one by one at the time of switching the substrate type, the operation rate is greatly reduced.

  Moreover, when there are many electronic component mounting machines arrange | positioned on the same production line, the batch replacement work time of an electronic component, ie, the stop time of a production line, will become long. Even in this case, the operation rate of the production line is greatly reduced.

  The feeder desorption time guidance method and production line management system of the present invention have been completed in view of the above problems. An object of the present invention is to provide a feeder detachment time guidance method and a production line management system in which the operation rate of a production line is unlikely to decrease.

  (1) In order to solve the above-described problem, the feeder removal / desorption time guidance method of the present invention includes a plurality of feeders on which a plurality of electronic components are arranged, and a feeder holding portion to which the feeders are detachably attached during production. A production line equipped with an electronic component mounting machine for mounting the electronic component on a board, a feeder removal timing guidance method, a production program creating step for creating a plurality of production programs for the board produced on the production line, Based on the production program, a desorption time guide for desorption time regarding at least one of the removal time and the attachment time of the feeder during production is created so that the desorption time can be recognized in the feeder unit. And a time guide creation step.

  The feeder desorption time guidance method of the present invention includes a production program creation step and a desorption time guidance creation step.

  In the production program creation step, production programs for a plurality of substrates produced using the same production line, such as half-day production, one-day production, three-day production, and one-week production, are created together. This step is executed before the production of a plurality of substrates is started.

  In the desorption time guide creation step, a desorption time guide for the feeder desorption time during production is created. The desorption time guide is created so that the operator can recognize the desorption time during production in units of feeders.

  In the case of the above-described methods of Patent Documents 1 and 2, it is determined whether or not the feeder needs to be replaced by focusing attention locally only before and after switching the substrate type. On the other hand, according to the feeder desorption time guidance method of the present invention, the desorption time guidance is created based on a production program for a plurality of substrates produced using the same production line. That is, the desorption time guide is created based on the entire production plan. For this reason, it can suppress that the operation rate of a production line falls.

  Moreover, according to the feeder removal / desorption time guidance method of the present invention, the removal / desorption time guide is created so that the operator can recognize the removal / desorption time during production in units of feeders. By referring to the desorption time guide, the operator can remove an unnecessary feeder even though the substrate is being produced. In addition, the operator can attach the necessary feeders even though the substrate is being produced. In addition, the operator can remove unnecessary feeders and attach necessary feeders while the board is being produced. Hereinafter, “removal” and “attachment” may be collectively referred to as “replacement”.

  Thus, according to the feeder attachment / detachment time guidance method of the present invention, the operator can perform the attachment / detachment operation of the feeder during the production of the substrate. For this reason, it can suppress that the operation rate of a production line falls.

  Further, according to the feeder desorption time guidance method of the present invention, the operator can confirm the feeder to be desorbed and the desorption time of the feeder by referring to the desorption time guidance. For this reason, the operator can freely determine at which timing within the detachment timing the detachment operation is performed. For example, the operator can perform the detachment work when his / her workload is light. Thus, according to the feeder attachment / detachment time guiding method of the present invention, the degree of freedom with respect to the attachment / detachment operation timing is increased.

  (2) Preferably, in the configuration of the above (1), the feeder holding portion includes a plurality of feeder mounting portions to which the feeders are individually detachably mounted, and the plurality of substrates include a first substrate and a first substrate. A plurality of production programs, the first program for producing the first substrate, and the second substrate executed after the first program in time series A plurality of feeders, the first feeder in which the electronic components used up to the first program are arranged, and the first feeder in which the electronic components used from the second program are arranged. The first feeder and the second feeder are attached to the same feeder attachment portion, and in the desorption time guide creating step, the first feeder The removal time of over, and the desorption timing guidance regarding the mounting time of the second feeder is better to adopt a configuration that is created.

  FIG. 1A shows a schematic diagram of a conventional substrate switching operation. FIG. 1B shows a schematic diagram of the substrate switching work of this configuration. FIGS. 1A and 1B are schematic diagrams for explaining the operational effects of the present configuration. For example, the contents of the present invention are not limited in any way, such as the number of feeder attachment portions, the number of production programs, the number and arrangement of feeders to be removed, and the number and arrangement of feeders to be attached.

  As shown in FIG. 1A, the feeder a1 (that is, the electronic component) of the feeder mounting portion A is used in the production program (that is, the substrate) from the first to the nth (n is an integer of 2 or more). . The feeder a1 is not used in the production program from the (n + 1) th. Further, the feeder b1 of the feeder mounting part B is used in the first to n + 1th production programs. The feeder b1 is not used in the production program from the (n + 2) th. Further, the feeder c1 of the feeder mounting portion C is used in the first to n + 2th production programs. The feeder c1 is not used in the production program from the (n + 3) th. On the other hand, the feeders a2, b2, and c2 are used in the production program from the (n + 4) th. Moreover, the feeder d1 of the feeder attachment part D is used in all production programs.

  Conventionally, as shown by hatching in FIG. 1A, the production line is stopped between the n + 3th program and the n + 4th program. Then, using the pallet exchanging carriage 104 shown in FIG. 7, the feeder a1 is replaced with the feeder a2, the feeder b1 is replaced with the feeder b2, and the feeder c1 is replaced with the feeder c2. For this reason, the operation rate of the production line was decreasing.

  In this regard, according to the present configuration, as shown in FIG. 1B, the removal timing of the first feeder (feeders a1, b1, c1) and the attachment timing of the second feeder (feeders a2, b2, c2). A guide is created.

  By referring to the desorption time guide, the operator recognizes that the replacement work of the feeder a1 and the feeder a2 with respect to the feeder mounting portion A may be executed between the n + 1th production program and the n + 3rd production program. can do. Further, the operator can recognize that the replacement work of the feeder b1 and the feeder b2 with respect to the feeder attachment portion B may be executed between the n + 2nd production program and the n + 3rd production program. Further, the operator can recognize that the replacement work of the feeder c1 and the feeder c2 with respect to the feeder attachment portion C may be executed in the (n + 3) th production program.

  The operator can also prioritize the three exchange operations. For example, in the (n + 3) th production program, the feeder c1 and the feeder c2 can be exchanged only in the production program. In the (n + 2) th production program, the production program and the (n + 3) th production program are exchanged. The feeder b1 and the feeder b2 that can only be executed in the machine are exchanged. In the (n + 1) th production program, the feeder a1 and the feeder a2 that can be executed from the production program to the (n + 3) th production program are exchanged. Can be determined by the operator.

  Thus, according to this structure, the stop time of the production line accompanying the batch exchange of a feeder can be shortened. For this reason, it can suppress that the operation rate of a production line falls. In addition, the degree of freedom with respect to the timing of the replacement work is increased. In addition, the exchange work can be distributed in time series. In addition, the operator's workload can be reduced.

  (3) Preferably, in the configuration of (1) or (2), the plurality of substrates include a third substrate, and the plurality of production programs produce the third substrate to be executed second or later. A plurality of feeders including a third feeder in which the electronic parts used from the third program are arranged, and in the desorption time guide creating step, the third feeder It is better to have a configuration in which the desorption time guide relating to the attachment time is created. Here, “second and subsequent” includes “second”.

  The third feeder is used from the third program. For this reason, the 3rd feeder should just be attached at the time of starting the 3rd program. Conversely, the third feeder may not be attached when the first program is started.

  According to this configuration, the operator can perform the installation work of the third feeder according to the use start time of the third feeder (execution time of the third program). For this reason, the freedom degree with respect to the timing of attachment work becomes high. In addition, the attaching operation can be distributed in time series. In addition, the operator's workload can be reduced.

It is better to adopt a configuration in which an item relating to the feeder mounting portion is set on one of the vertical axis and the horizontal axis, and an item relating to the production program is set on the other side, respectively.

  According to this configuration, it is possible to create a list form desorption time guide table for a plurality of production programs. For this reason, at the stage before the start of the production of a plurality of substrates, it is possible to recognize the attachment / detachment timing in a bird's-eye view with respect to all the feeders. Therefore, it is easy to grasp the degree of work load. For example, measures such as increasing the number of operators can be prepared in advance in a time period in which the removal / attachment times of a plurality of feeders overlap.

  (5) In order to solve the above problems, a production line management system according to the present invention includes a plurality of feeders in which a plurality of electronic components are arranged, and a feeder holding unit to which the feeders are detachably attached during production.

That is, the desorption time guide is created based on the entire production plan. For this reason, it can suppress that the operation rate of a production line falls.

  Moreover, according to the production line management system of the present invention, the desorption time guide is created so that the operator can recognize the desorption time during production in units of feeders. By referring to the desorption time guide, the operator can remove an unnecessary feeder even though the substrate is being produced. In addition, the operator can attach the necessary feeders even though the substrate is being produced.

  Further, according to the production line management system of the present invention, the operator can confirm the feeder to be attached / detached and the attachment / detachment time of the feeder by referring to the guide for attaching / detaching. For this reason, the operator can freely determine at which timing within the detachment timing the detachment operation is performed. For example, the operator can perform the detachment work when his / her workload is light. Thus, according to the production line management system of the present invention, the degree of freedom with respect to the timing of the detachment work is increased.

  According to this configuration, as in the configuration of (2) above, it is possible to shorten the production line stop time associated with batch replacement of feeders. For this reason, it can suppress that the operation rate of a production line falls. In addition, the degree of freedom with respect to the timing of the replacement work is increased. In addition, the exchange work can be distributed in time series. In addition, the operator's workload can be reduced.

<Feeder removal time guidance method>
Next, the feeder removal time guidance method of this embodiment will be described. Hereinafter, the production line Lf will be described on behalf of the production lines Lf and Lr. The feeder attachment / detachment timing guidance method of the present embodiment is executed by the integrated control device 9. The feeder desorption time guidance method has a production program creation step and a desorption time guidance creation step.

[Production program creation step]
In this step, the integrated control device 9 creates 34 types of production programs for the substrates Bf. That is, the person in charge of mounting all electronic components on the board Bf is assigned to the electronic component mounters 1a to 1d. Specifically, it is determined which electronic component mounter 1a to 1d uses which tape feeder 4 and which electronic component is to be mounted on each of the 34 types of substrates Bf.

[Desorption time guidance creation step]
In this step, the integrated control device 9 creates a desorption time guide table. FIG. 5 shows a desorption time guidance table created by the feeder desorption time guidance method of the present embodiment. FIG. 5 shows only the charge for the electronic component mounting machine 1a. A similar desorption time guide table is created for the electronic component mounting machines 1b to 1d. As shown in FIG. 2, the desorption time guide table is transmitted from the general control device 9 to the control devices 6 of the respective electronic component mounting machines 1a to 1d. The transmitted desorption time guide table is displayed on the display unit 37.

  In FIG. 5, the item “Pos.” On the vertical axis is the slot number (No. 1 to 45) of the slot 50 of the device palette 5 of FIG. 4. The item “production order” on the horizontal axis is a production program (No. 1 to No. 34). The item “Qty” below the horizontal axis is the number of electronic components mounted. For example, Pos. “15” entered in the 11 production order 2 space is the tape feeder 4 arranged in the 11th slot 50 of the electronic component mounting machine 1a for the board Bf produced by the second production program. This indicates that a total of 15 electronic components are mounted.

  The operator can recognize the desorption time of the tape feeder 4 by looking at the desorption time guide table of FIG.

  First, a method for recognizing the replacement time of the tape feeder 4 will be described. As shown in FIG. 5, Pos. 11, 15, 19, 23 to 30, 32, 33, and 35 are each provided with a thick solid line frame. As a result, the operator recognizes that the tape feeder 4 attached to the slot 50 needs to be replaced with a tape feeder 4 of a different component type at any timing during the execution of the 34 production programs. .

  In addition, when Qty (the number of mounted parts) of electronic components used in the order of the production program for an arbitrary item “Pos.” Surrounded by the thick solid line frame, the time when Qty = 0 continues (thick solid line frame) There is a section surrounded by This section corresponds to the “desorption time” of the present invention. In the production programs on both the left and right sides of the detachment time, the types of electronic parts used are different. For this reason, it is necessary to replace the tape feeder 4 at any timing within the detachment time.

  For example, Pos. In the case of 11 (slot number 11), 15 electronic components are used in the second production program. Electronic parts are not used in the detachment time (the section from the third production program to the 28th production program). In the 29th production program, 10 electronic components are used. Here, the electronic component used in the second production program is different from the electronic component used in the 29th production program. For this reason, Pos. It is necessary to remove the tape feeder 4 for the second production program from the 11 slots 50. In addition, at any timing within the desorption time, Pos. It is necessary to attach the tape feeder 4 for the 29th production program to the 11th slot 50.

  Thus, the operator can recognize the replacement time of the tape feeder 4 by looking at the removal / desorption time.

  Next, a method for recognizing the attachment time of the tape feeder 4 will be described. As an example, Pos. 2) When Qty (the number of mounted parts) of electronic parts used in the order of the production program is viewed, the period when Qty = 0 continues from the first production program to the 14th production program (enclosed by a thick dotted frame) Section). This section corresponds to the “desorption time” of the present invention. The operator can check the Pos. It can be recognized that the tape feeder 4 may be attached to the slot 50 of No. 2 (slot number 2) before the 15th production program is started. In other words, when the 1st to 14th production programs are started, Pos. It can be recognized that it is not necessary to attach the tape feeder 4 to the second slot 50.

  Next, a method for recognizing the removal time of the tape feeder 4 will be described. As an example, Pos. 2, when Qty (the number of mounted parts) of electronic parts used in the order of the production program is viewed, when Qty = 0 continues from the 19th production program to the 34th (final) production program (thick dashed line) There is a section surrounded by a frame). This section corresponds to the “desorption time” of the present invention. By checking the desorption time, the operator can use the Pos. It can be recognized that the tape feeder 4 can be removed from the slot 50 of No. 2 (slot number 2).

<Effect>
Next, the effect of the feeder attachment / detachment time guidance method and production line management system of the present invention will be described. According to the feeder desorption time guidance method and the production line management system 8 of the present embodiment, 34 types of substrates Bf (or substrates Br) produced using the same production line Lf (or production line Lr) shown in FIG. The desorption time guide table shown in FIG. 5 is created based on the production program. That is, the desorption time guide table is created based on the entire production plan for the substrates Bf and Br. For this reason, it can suppress that the operation rate of the production lines Lf and Lr falls.

  Further, according to the feeder desorption time guidance method and the production line management system 8 of this embodiment, the desorption illustrated in FIG. 5 is performed so that the operator can recognize the desorption time during production for each slot 50 (that is, in units of four tape feeders). A timetable is created.

  By referring to the desorption time guide table, the operator can remove the unnecessary tape feeder 4 even though the board is being produced (even though the electronic component mounting machines 1a to 1d are moving). . For example, after completion of the 18th production program, Pos. The tape feeder 4 can be removed from the slot 50 of No. 2 (slot number 2).

  Further, the operator can attach the necessary tape feeder 4 despite the substrate production. For example, by the start of the 15th production program, Pos. The tape feeder 4 can be attached to the slot 50 of 2 (slot number 2).

  Further, the operator can remove the unnecessary tape feeder 4 and attach the necessary tape feeder 4 while the substrate is being produced. That is, the tape feeder 4 can be replaced. For example, between the third production program and the 28th production program, Pos. The unnecessary tape feeder 4 can be removed from the slot 50 of 11 (slot number 11), and the necessary tape feeder 4 can be attached to the slot 50.

  Thus, according to the feeder attachment / detachment timing guidance method and the production line management system 8 of the present embodiment, the operator can perform the attachment / detachment operation of the tape feeder 4 during substrate production. For this reason, the stop time of the production lines Lf and Lr can be shortened compared with the case where the tape feeder 4 is replaced at once. Therefore, it can suppress that the operation rate of the production lines Lf and Lr falls.

  Further, according to the feeder desorption time guidance method and the production line management system 8 of the present embodiment, the operator can refer to the desorption time guidance table shown in FIG. Can be confirmed. For this reason, the operator can freely determine at which timing within the detachment timing the detachment operation is performed.

  For example, Pos. It is necessary to attach the tape feeder 4 to the slot 50 of No. 2 (slot number 2) before the 15th production program is started. Here, in the second production program, Pos. 2 (slot number 2), Pos. 32 (slot number 32) is overlapped with the removal timing. In the third to fifth production programs, in addition to the above desorption time, Pos. 11 (slot number 11) and Pos. 35 (slot number 35) is overlapped. In the sixth to ninth production programs, in addition to the above desorption time, Pos. 33 (slot number 33) is overlapped. In the 10th production program, in addition to the above desorption time, Pos. 26 (slot number 26) is overlapped. In addition, in the 11th to 14th production programs, in addition to the above desorption time, Pos. 19 (slot number 19) and Pos. 23 (slot number 23) is overlapped.

  On the other hand, in the first production program, Pos. There is no desorption time overlapping with the desorption time of 2 (slot number 2). For this reason, the operator can change the Pos. It is possible to decide to attach the tape feeder 4 to the slot 50 of 2 (slot number 2). Thus, according to the feeder attachment / detachment timing guidance method and the production line management system 8 of the present embodiment, the degree of freedom with respect to the timing of the attachment / detachment work is increased.

  Further, according to the feeder desorption time guidance method and the production line management system 8 of the present embodiment, as shown in FIG. 5, the desorption time guidance table is created in the form of a list. For this reason, it is possible to recognize the detachment timing for each tape feeder 4 in units of feeders before the production of the substrates Bf and Br. Therefore, it is easy to grasp the degree of work load. For example, measures such as increasing the number of operators can be prepared in advance in a time period in which the removal timings of the plurality of tape feeders 4 overlap (for example, the 27th production program shown in FIG. 5).

  Further, according to the feeder desorption time guide method and the production line management system 8 of the present embodiment, the tape 40 of the tape feeder 4 can be applied to the tape feeder 4 while the tape feeder 4 is stopped by referring to the desorption time guide table shown in FIG. On the other hand, a new tape 40 can be added. Further, the tape 40 can be exchanged for each reel 41.

  For example, Pos. The tape feeder 4 of the slot 50 of 17 (slot number 17) is used in the ninth and 27th production programs, but is not used in the 10th to 26th production programs. That is, it is resting. The tape 40 can be added to the tape 40 of the tape feeder 4 by using this pause time. Further, the entire tape 40 can be replaced.
