Description

  The present invention relates to a mounting condition determination method for a component mounter in a production line including one or more component mounters for mounting components on a substrate.

  2. Description of the Related Art Conventionally, in a component mounter that mounts a component on a board, a mounting condition determination method is optimized in order to mount the component with a shorter tact (mounting time).

  As this mounting condition determination method, there has been proposed a component mounting method capable of minimizing tact by arranging parts of the same type divided into a plurality of component cassettes (for example, Patent Document 1). reference). The component cassette is a cassette for storing components. The mounting head sucks the components stored in the component cassette.

In this component mounting method, the mounting head simultaneously picks up a plurality of components and mounts them on the substrate. A plurality of component cassettes are arranged so that the number of components that are simultaneously attracted by the mounting head is maximized. At this time, for example, when the number of components of the same type to be mounted is large, the components of the same type are divided and arranged in a plurality of component cassettes. This minimizes the number of times the mounting head picks up the component. As described above, the same type of components are divided and arranged in a plurality of component cassettes, and therefore, the tact for mounting the components by the mounting head can be minimized.
Japanese Patent No. 3466141

  However, in the mounting condition determination method for the component mounting machine described above, the same type of components are divided and arranged in a plurality of component cassettes, so the number of component cassettes that store the components increases. Then, there is a problem that the increase in the number of component cassettes leads to an increase in cost such as an increase in the number of component cassettes in stock.

  Further, when the number of component cassettes is reduced, the tact of the component mounting machine increases, so that there is a possibility that the target production time may be exceeded, and there is a problem that production efficiency is lowered.

  Therefore, the present invention has been made in view of such circumstances, and in order to suppress an increase in cost while maintaining production efficiency, the number of component cassettes can be reduced without exceeding the target production time. An object of the present invention is to provide a mounting condition determination method for such a component mounting machine.

In order to achieve the above object, a mounting condition determination method according to the present invention targets a production line including one or more component mounting machines for mounting components on a board, and supplies components supplied from a component cassette that stores the components. A method for determining mounting conditions of a component mounting machine to be mounted, wherein the number of component divisions temporarily set so that the number of component divisions, which is the number of component cassettes storing the same type of components, is smaller than the set value. A temporary setting value acquisition step to acquire, a mounting time calculation step to calculate a mounting time for mounting a component on a board, using the number of component divisions acquired in the temporary setting value acquisition step as a mounting condition; and the mounting time calculation step. A mounting time determination step for determining whether or not the calculated mounting time exceeds a target production time, and it is determined in the mounting time determination step that the mounting time does not exceed a target production time. If it is, the and a component division number setting step of resetting the temporarily set mounted condition the part number of divisions, the in provisional setting value acquisition step, the value mounting time is the set so as to minimize The provisional number of component divisions is acquired so as to increase the mounting time in the number of component divisions and approach the target production time, and in the mounting time calculation step, the same type arranged in one component supply unit The mounting time is defined as a mounting condition in which the components of one or more component cassettes storing the components are stored in another component cassette storing the same type of components arranged in the component supply unit. It is characterized by calculating .

  Thereby, the number of parts cassettes can be reduced without exceeding the target production time as follows.

  When there are a plurality of component mounters on the production line, the component cassette is set so that each of the plurality of component mounters has a minimum tact. Here, the largest tact among the tacts of the plurality of component mounting machines is referred to as a line tact. That is, the line tact is a tact that becomes a bottleneck in the production line.

  Then, a waiting time is generated in a component mounting machine having a tact smaller than the line tact among a plurality of component mounting machines until the mounting operation of the line tact component mounting machine is completed. The line tact does not change if this waiting time is more or less. That is, even if the tact of some component mounting machines becomes smaller than the line tact, the line tact does not decrease.

  In each component mounter, the same type of component is arranged in one or a plurality of component cassettes so that the tact is minimized. For this reason, when the same type of components are divided and arranged in a plurality of component cassettes so that the tact is minimized, the same type of components can be additionally divided into a plurality of component cassettes. There is sex. That is, the parts cassette is used extra.

  Further, when the target production time is longer than the line tact, such as when the delivery time of the product is long, an extra part cassette is used. In this case, even if there is only one component mounter on the production line, an extra component cassette is used.

  For this reason, when there are one or more component mounters on the production line, the number of component cassettes to which the same type of component is supplied can be reduced with a tact not exceeding the target production time. That is, when the same type of components are divided and arranged in a plurality of extra component cassettes, the extra component cassettes can be reduced.

  The present invention can be realized not only as such a mounting condition determination method, but also as a device or program for determining mounting conditions according to the method, and a storage medium for storing the program. Furthermore, the present invention can also be realized as a component mounter that mounts components on a board by determining mounting conditions according to the method.

  According to the present invention, in a production line having one or more component mounting machines, by providing a mounting condition determination method that reduces excess component cassettes with a tact that does not exceed the target production time, it is possible to reduce the cost while maintaining production efficiency. Therefore, the practical value of the present invention is extremely high.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an external view showing a configuration of a component mounting system 10 that realizes a mounting condition determination method according to the present invention.

  The component mounting system 10 is a production line that mounts components on a substrate 20 to produce a circuit board, and includes a mounting condition determination device 100 and a plurality of component mounters 200 to 500 (in the example shown in FIG. 1, nine components). Mounting machine). The component mounters 200 to 500 are hereinafter referred to as a component mounter 200 or the like.

  The mounting condition determining apparatus 100 is an apparatus that executes the mounting condition determining method according to the present invention. The mounting condition determining apparatus 100 determines mounting conditions so that an extra component cassette can be reduced with a tact not exceeding the target production time. This target production time is assumed to be a line tact. That is, the mounting condition determining apparatus 100 can reduce the extra component cassette that leads to an increase in cost without increasing the line tact.

  Each of the component mounting machines 200 and the like mounts a component such as an electronic component on the board 20 as a part of the component mounting system 10 under the conditions determined by the mounting condition determining apparatus 100.

FIG. 2 is a diagram illustrating a configuration of a plurality of component mounters 200 and the like of the component mounting system 10.
The plurality of component mounting machines 200 and the like mount components while feeding the substrate 20 from upstream to downstream. That is, first, the upstream component mounter 200 receives the board 20 and mounts the component on the board 20. Then, the board 20 on which the component is mounted is sent to the component mounter 300 on the downstream side. In this manner, similarly, the board 20 sent out from the component mounting machine 300 is sequentially sent from the component mounting machine 400 to the component mounting machine 500 to mount the components.

  FIG. 3 is a plan view showing the main components inside the component mounter 200 and the like. The component mounter 200 will be described below, but the component mounters 300 to 500 are the same as the component mounter 200.

  The component mounter 200 includes two mounting units 210 a and 210 b that mount components on the substrate 20. The two mounting units 210a and 210b cooperate with each other to perform a mounting operation on one board 20.

  The mounting unit 210a and the mounting unit 210b have the same configuration. That is, the mounting unit 210a includes a component supply unit 211a, a mounting head 213a, and a component recognition camera 214a. Similarly, the mounting unit 210b includes a component supply unit 211b, a mounting head 213b, and a component recognition camera 214b.

  Note that the nozzle station, tray supply unit, and the like are not the main point of the present invention, and are not shown in the figure.

  Here, a detailed configuration of the mounting unit 210a will be described. Note that the detailed configuration of the mounting unit 210b is the same as that of the mounting unit 210a, and is omitted. In the following description, the mounting unit 210a will be described, but the mounting unit 210b is the same unless otherwise specified.

  The component supply unit 211a includes an array of a plurality of component cassettes 212a that store component tapes. The component tape is, for example, a plurality of components of the same component type arranged on a tape (carrier tape) and supplied in a state of being wound on a reel or the like. The parts arranged on the part tape are, for example, chips, and specifically, 0402 chip parts and 1005 chip parts.

  The mounting head 213a can include, for example, a maximum of 10 suction nozzles, and can mount a maximum of 10 components from the component supply unit 211a and mount them on the substrate 20.

  The component recognition camera 214a is used to photograph the component sucked by the mounting head 213a and inspect the suction state of the component two-dimensionally or three-dimensionally.

FIG. 4 is a schematic diagram showing the positional relationship between the mounting head 213a and the component cassette 212a.
As described above, for example, a maximum of ten suction nozzles nz can be attached to the mounting head 213a. The mounting head 213a to which the ten suction nozzles nz are attached can suck components from each of a maximum of ten component cassettes 212a at the same time (by one up and down movement).

FIG. 5 is a diagram illustrating an example of a component tape and a reel that contain components.
Components such as chip-type electronic components are stored in a storage recess 221a continuously formed at a predetermined interval on a carrier tape 221 shown in FIG. 5, and a cover tape 222 is attached to the upper surface and packaged. The carrier tape 221 with the cover tape 222 attached in this way is supplied to the user in a taping form wound around the reel 223 by a predetermined quantity. The carrier tape 221 and the cover tape 222 constitute a component tape. The configuration of the component tape may be other than the configuration shown in FIG.

  The mounting unit 210a of such a component mounting machine 200 moves the mounting head 213a to the component supply unit 211a and causes the mounting head 213a to attract the component supplied from the component supply unit 211a. Then, the mounting unit 210a moves the mounting head 213a onto the component recognition camera 214a at a constant speed, causes the component recognition camera 214a to capture images of all the components sucked by the mounting head 213a, and accurately determines the component suction position. To detect. Further, the mounting unit 210 a moves the mounting head 213 a to the substrate 20 and sequentially mounts all the sucked components on the mounting points of the substrate 20. The mounting unit 210a mounts all the predetermined components on the board 20 by repeatedly performing such operations of suction, movement, and mounting by the mounting head 213a.

  Similarly to the mounting unit 210a, the mounting unit 210b also repeatedly performs the operations of suction, movement, and mounting by the mounting head 213b to mount all the predetermined components on the board 20.

  Then, each of the mounting unit 210a and the mounting unit 210b picks up a component from the component supply unit when the counterpart mounting unit is mounting the component, and conversely, the counterpart mounting unit picks up the component from the component supply unit. When mounting the components, the components are alternately mounted on the board 20 so as to mount the components. In other words, the component mounter 200 is configured as a so-called alternating component mounter.

Similarly, the suction nozzles nz from No. 5 to No. 8 are arranged in order in the X-axis direction from the position where the coordinate value is small in the Y-axis direction and the smallest in the X-axis direction.

  Here, it is assumed that the time for the mounting head 213a to move is 1 second (hereinafter referred to as 1s), which is the distance x between the suction nozzles nz adjacent in the X-axis direction. For example, the time for the first suction nozzle nz to move to the position of the second suction nozzle nz is 1 s. Similarly, it is assumed that the time for the mounting head 213a to move the distance y between the suction nozzles nz adjacent in the Y-axis direction is 1 s. For example, the time required for the first suction nozzle nz to move to the position of the fifth suction nozzle nz is 1 s.

  Then, the mounting head 213a moves a distance of 2x in the direction opposite to the X-axis direction. Then, the third and fourth suction nozzles nz suck the components one by one from the two component cassettes 212a (FIG. 7B). It takes 2 s for the mounting head 213a to move through this 2x distance.

  Further, the mounting head 213a moves by a distance of 2x in the X-axis direction, so that the suction nozzles nz of No. 5 and No. 6 suck the components one by one from the two component cassettes 212a (FIG. 7D). . It takes 2 s for the mounting head 213a to move this 2x distance.

  As a result, when the number of component divisions is 2, the total movement time until the mounting head 213a sucks the components to all the suction nozzles nz is 5 s.

  FIG. 9 is a diagram showing a process until the mounting head 213a sucks components to all the suction nozzles nz when the number of component divisions is three as a third case. Three component cassettes 212a are arranged in the component supply unit 211a.

The mounting head 213a has eight suction nozzles nz as in FIGS.
First, the No. 1, No. 2 and No. 3 suction nozzles nz pick up components one by one from the three component cassettes 212a (FIG. 7A).

  Then, the mounting head 213a moves a distance x in the direction opposite to the X-axis direction. Then, one of the four suction nozzles nz is picked up from the right part cassette 212a (FIG. 7B). It takes 1 s for the mounting head 213a to move through this x distance.

  Then, the mounting head 213a moves by a distance y in the Y-axis direction. Then, the suction nozzles nz of No. 6, No. 7 and No. 8 suck the components one by one from the three component cassettes 212a (FIG. 7C). It takes 1 s for the mounting head 213a to move this distance y.

  Further, the mounting head 213a moves by a distance x in the X-axis direction. Among the three suction nozzles nz of No. 5, one part is picked up from the left part cassette 212a (FIG. 7D). It takes 1 s for the mounting head 213a to move this distance x.

  As a result, when the number of component divisions is 3, the total movement time until the mounting head 213a sucks the components to all the suction nozzles nz is 3 s.

  FIG. 10 is a diagram illustrating a process until the mounting head 213a sucks components to all the suction nozzles nz when the number of component divisions is four as the fourth case. Four component cassettes 212a are arranged in the component supply unit 211a.

  The mounting head 213a has eight suction nozzles nz as in FIGS.

  Thus, when the number of component divisions increases, the total movement time of the mounting head 213a decreases. That is, in the component mounter 200 for mounting components on the board 20, the tact decreases when the number of component divisions increases, and conversely, the tact increases when the number of component divisions decreases.

  FIG. 12 is a block diagram showing a functional configuration of the mounting condition determining apparatus 100 in the present embodiment.

  The mounting condition determination apparatus 100 is a computer that performs processing such as determination of the number of component divisions in which the line tact does not increase so as to reduce extra component cassettes for each component mounting machine. The mounting condition determining apparatus 100 includes an arithmetic control unit 101, a display unit 102, an input unit 103, a memory unit 104, a program storage unit 105, a communication I / F (interface) unit 106, and a database unit 107.

  The mounting condition determining apparatus 100 is realized by a general-purpose computer system such as a personal computer executing the program according to the present invention, and is not connected to the component mounter 200 or the like, but is a stand-alone simulator (mounting condition). It also functions as a determination tool. Note that the function of the mounting condition determining apparatus 100 may be provided in the component mounter 200 or the like.

  The arithmetic control unit 101 is a CPU (Central Processing Unit), a numerical processor, or the like, and loads and executes a necessary program from the program storage unit 105 to the memory unit 104 in accordance with an instruction from an operator or the like. Each component 102-107 is controlled.

  The display unit 102 is a CRT (Cathode-Ray Tube), an LCD (Liquid Crystal Display), or the like, and the input unit 103 is a keyboard, a mouse, or the like. These are mounted condition determination devices under the control of the arithmetic control unit 101. 100 is used for dialogue between an operator and the like.

  The communication I / F unit 106 is a LAN (Local Area Network) adapter or the like, and is used for communication between the mounting condition determining apparatus 100 and the component mounting machine 200 or the like. The memory unit 104 is a RAM (Random Access Memory) or the like that provides a work area for the arithmetic control unit 101.

  The database unit 107 includes input data (mounting point data 107a, component library 107b, etc.) used for mounting condition determination processing by the mounting condition determination device 100, and a component supply unit generated as a result of processing by the mounting condition determination device 100. Is a hard disk or the like that stores data (part cassette number setting data 107c, part cassette data 107d, processed data 107e) and the like indicating information on the parts cassette in FIG.

  13 to 17 are diagrams showing examples of the mounting point data 107a, the component library 107b, the component cassette number setting data 107c, the component cassette data 107d, and the processed data 107e, respectively.

FIG. 13 is a diagram illustrating an example of the mounting point data 107a.
The mounting point data 107a is a collection of information indicating mounting points of all components to be mounted. One mounting point pi includes a component type ci, an X coordinate xi, a Y coordinate yi, control data φi, and a mounting angle θi. Here, the component type corresponds to a component name in the component library 107b shown in FIG. 14, the X coordinate and the Y coordinate are coordinates of a mounting point (coordinates indicating a specific position on the board 20), and the control data is , The restriction information (mounting nozzle type that can be used, the maximum movement acceleration of the mounting head, etc.) regarding the mounting of the component is shown. The mounting angle θi indicates an angle at which the nozzle that sucks the component of the component type ci should rotate. NC (Numeric Control) data to be finally obtained is an arrangement of mounting points that minimizes the line tact.

FIG. 14 is a diagram illustrating an example of the component library 107b.
The component library 107b is a library that collects unique information about all component types that can be handled by the component mounter 200 and the like. As shown in FIG. 14, the component library 107b includes component size for each component type (component name), tact (tact specific to the component type under a certain condition), and other restriction information (types of usable suction nozzles). , Recognition method by component recognition camera, maximum acceleration ratio of mounting head, etc.). In the drawing, the external appearance of the components of each component type is also shown for reference. In addition, the component library 107b may include information such as the color and shape of the component.

FIG. 15 is a diagram showing an example of the component cassette number setting data 107c.
The component cassette number setting data 107c is a collection of information on the number of component cassettes for each component type for setting the number of component cassettes to be supplied to a component supply unit such as the component mounter 200. The component cassette number setting data 107c includes a table name, a component type, a set cassette number for each component type, a temporarily set cassette number, a reset cassette number, and the like.

  Here, the table name is a name that identifies the table. The table refers to an assembly of component cassettes supplied to the component supply unit, and each of the component mounters 200 and the like has two tables. For example, an assembly of component cassettes 212a supplied to the component supply unit 211a is referred to as a table 1, and an assembly of component cassettes 212b supplied to the component supply unit 211b is referred to as a table 2.

The component type refers to the component name of the component library 107b shown in FIG. 14 for each table.
The number of set cassettes is the number of component cassettes for each initially set component type. That is, the set cassette number is an initial set value of the number of parts divided. Note that the number of component cassettes optimized so as to minimize the tact of the component mounter 200 and the like is initially set.

  The provisionally set number of cassettes is the number of component cassettes temporarily set when setting the number of component cassettes smaller than the set number of cassettes. That is, the temporarily set cassette number is a temporarily set value of the number of parts divided. This provisionally set number of cassettes is set in response to an instruction from the input unit 103.

  The reset cassette number is the number of component cassettes after resetting when the set cassette number is reset. That is, the reset cassette number is the number of parts division after resetting. If a certain condition is satisfied with the temporarily set number of cassettes, the number of temporarily set cassettes is reset and set as the number of cassettes.

FIG. 16 is a diagram illustrating an example of the component cassette data 107d.
The parts cassette data 107d is a collection of parts cassette information before and after review in each table. The component cassette data 107d includes a table name, a component cassette, a component type for each component cassette, a combined cassette, a revised cassette, and the like.

  Here, the component type refers to the component name of the component library 107b shown in FIG. 14 for each component cassette in each table.

  The coupling cassette is a component cassette that can be reduced by supplying the stored components to another component cassette.

  The after-review cassette is a parts cassette after the parts stored in the combined cassette are supplied. For example, in the table 3, the cassette 11 of the revised cassette is a component cassette after the components stored in the cassette 12 are supplied to the cassette 11. Note that the component cassette that is the target of the combined cassette is deleted from the revised cassette.

FIG. 17 is a diagram illustrating an example of the processed data 107e.
The processed data 107e includes a processed list A and a processed list B. Both the processed list A and the processed list B are lists indicating the component cassettes for which it is determined whether or not the line tact is deteriorated by the combination when the combination cassette of the component cassette data 107d is selected. That is, in the processed list A and the processed list B, component cassettes that have been combined and deleted, or component cassettes that have not been combined are written.

  The program storage unit 105 illustrated in FIG. 12 is a hard disk or the like that stores various programs that implement the functions of the mounting condition determining apparatus 100. The program is a program for determining a mounting condition by the component mounter 200 or the like, and functionally (as a processing unit that functions when executed by the arithmetic control unit 101), a temporary setting value acquisition unit 105a, a mounting time calculation unit 105b, a mounting time determination unit 105c, and a component division number setting unit 105d.

  The temporary setting value acquisition unit 105 a acquires the value of the temporary setting cassette number of the component cassette number setting data 107 c shown in FIG. 15 from the operator via the input unit 103. Note that this temporarily set cassette number is temporarily set so as to be smaller than the set cassette number for the same component type. That is, the provisionally set number of cassettes is provisionally set so that the number of component divisions is smaller than the set value.

  The mounting time calculation unit 105b calculates the tact by arranging the component cassettes so that the number of component cassettes is equal to the number of temporary setting cassettes acquired by the temporary setting value acquisition unit 105a. As an example of the tact calculation, the component cassettes are arranged in descending order of the number of components, and the components are mounted from the components with the smallest number of components. As a result, the total time of suction, movement, and mounting of the mounting head can be shortened, and fewer tacts are calculated.

  The mounting time determination unit 105 c determines whether or not the tact calculated by the mounting time calculation unit 105 b exceeds the line tact of the component mounting system 10. The line tact may be a maximum tact determined from a plurality of component mounters by simulation or may be a value actually measured.

  When the mounting time determination unit 105c determines that the tact does not exceed the line tact of the component mounting system 10, the component division number setting unit 105d re-sets the temporarily set cassette number in the component cassette number setting data 107c. And Note that the arrangement of the component cassette after the resetting is reflected in the cassette after the review of the component cassette data 107d.

  18 and 19 are diagrams for explaining an example of the mounting condition determining method of the mounting condition determining apparatus 100 in the present embodiment.

  FIG. 18A is a diagram illustrating the tact of each component mounter in the component mount system 10 including the three component mounters 200 to 400.

  The three component mounting machines 200 to 400 mount components while feeding the substrate 20 from upstream to downstream. That is, first, the upstream component mounter 200 receives the board 20 and mounts the component on the board 20. Then, the board 20 on which the component is mounted is sent to the component mounter 300 on the downstream side. In this way, similarly, the board 20 sent out from the component mounter 300 is sent to the component mounter 400 to mount the components.

  As described above, in the process in which the plurality of substrates 20 are sequentially sent, the three component mounting machines 200 to 400 start mounting the components on the substrate 20 at the same time.

  Further, as shown in FIG. 18B, the component mounting order of the three component mounters 200 to 400 is optimized so that the tact time is minimized, and is 60 s, 40 s, and 20 s, respectively. . That is, the line tact is 60 s. In this optimization, components of the same component type may be divided and supplied to a plurality of component cassettes so that the tact is minimized. For example, as shown in FIG. 18A, four component cassettes 212a in which the components A are stored are arranged in the component supply unit 211a of the component mounter 200. Similarly, the components B to F are divided and arranged in a plurality of component cassettes. For convenience of explanation, the component cassettes 212a, 212b, 312a, 312b, 412a, and 412b in which the components A to F are accommodated are greatly illustrated.

  Note that the table 1 of the component cassette number setting data 107c shown in FIG. 15 corresponds to the component cassette 212a, and the table 2 corresponds to the component cassette 212b. Similarly, the table 3 corresponds to the component cassette 312a, and the table 4 corresponds to the component cassette 312b.

  When the plurality of substrates 20 are transferred to the three component mounters 200 to 400, the three component mounters 200 to 400 simultaneously start mounting the components on the substrate 20. Then, since the line tact is 60 s, the component mounter 300 and the component mounter 400 need to wait for 20 s and 40 s, respectively, after the component mounting is completed. That is, the component mounter 300 and the component mounter 400 do not increase the line tact even if the tact increases by 20 s and 40 s, respectively.

  Here, as shown in FIG. 11, the tact increases as the number of component divisions decreases. Therefore, in the component mounter 300 and the component mounter 400, the number of component cassettes 312a, 312b, 412a, or 412b can be reduced so that the line tact does not increase. For example, when the parts C of the same part type are divided and supplied to two parts cassettes 312a, the parts of the two divided parts cassettes 312a are returned to one parts cassette 312a, so that the parts The number of cassettes 312a can be reduced by one. Returning the parts of the two divided parts cassettes to one parts cassette is hereinafter referred to as combining.

  FIG. 19 is a diagram for explaining how to reduce the number of component divisions of the component mounter so that the line tact does not increase in the component mounting system 10 of FIG.

  Since the tact is a line tact, the component mounter 200 cannot reduce the component cassette 212a and the component cassette 212b in which the component A and the component B are stored.

  The component mounter 300 does not increase the line tact even if the tact increases by 20 s. Therefore, for example, the number of the component cassettes 312a can be reduced by combining the component cassettes 312a in which the components C are stored.

  First, the temporary setting value acquisition unit 105a acquires the temporary setting cassette number of the component cassette number setting data 107c. In FIG. 15, the component cassette 312 a in which the component C is stored has four provisional cassettes while the number of cassettes is five. Then, the mounting time calculation unit 105b calculates the tact so that there are four component cassettes 312a.

  Then, the mounting time determination unit 105 c determines whether or not the tact calculated by the mounting time calculation unit 105 b exceeds the line tact of the component mounting system 10.

  If the mounting time determination unit 105c determines that the tact does not exceed the line tact of the component mounting system 10, the component division number setting unit 105d sets the component cassette number setting data 107c for the component cassette 312a of the component C. Set the number of cassettes to 4 again.

  In FIG. 19A, one component cassette 312a for component C and two component cassettes 312b for component D can be reduced. As shown in FIG. 19B, the tact increased from 40 s to 55 s, but the line tact does not increase because it is 60 s or less of the line tact.

  Similarly, in the component mounting machine 400, as shown in FIG. 19A, two component cassettes 412a for component E and one component cassette 412b for component F can be reduced. And as shown in FIG.19 (b), although the tact increased from 20 s to 30 s, since it is 60 s or less of the line tact, the line tact does not increase.

  Thus, when the parts of the same part type are divided and arranged in a plurality of extra parts cassettes, the extra parts cassette can be reduced.

  20 and 21 are flowcharts showing an example of the operation of the mounting condition determining apparatus 100 in the present embodiment.

  FIG. 20 is a flowchart showing that the component cassette combining step is performed on all tables.

  In the mounting condition determining apparatus 100, component cassettes optimized so as to minimize the tact of the component mounting machine 200 and the like are set for each table. Then, the mounting condition determining apparatus 100 determines the mounting conditions for each table of the component mounter 200 and the like. Here, it is assumed that the component mounting system 10 includes the three component mounters 200, 300, and 400 shown in FIG. That is, since the component mounter 200 and the like each have two tables, the component mounting system 10 has six tables. These six tables are referred to as tables 1 to 6.

  First, the temporary setting value acquisition unit 105a acquires the value of the temporary setting cassette number of the component cassette number setting data 107c from the operator via the input unit 103 (S100). This provisionally set number of cassettes is a numerical value in which the number of component cassettes to which parts of the same component type are supplied is smaller than the set number of cassettes.

  Then, the table cassette 1 is targeted (S101), and the component cassette combining step is executed (S102). Here, the component cassette coupling step is a step of coupling the component cassettes so that the number of component cassettes is equal to the temporarily set number of cassettes. The details of the component cassette coupling step will be described later in the description of FIG.

  Next, the table 2 is targeted (S104), and the component cassette combining step is executed in the same manner as the table 1 (S106, S101, S102). In this way, the component cassette combining step is executed for all six tables.

FIG. 21 is a flowchart showing the component cassette coupling step.
A table such as the component mounter 200 is provided with a plurality of component cassettes. Here, it is assumed that each of the six tables has 20 component cassettes. These 20 component cassettes are referred to as cassettes 1-20.

  The mounting time calculation unit 105b calculates the tact by combining the component cassettes so that the number of the component cassettes is equal to the temporarily set number of the component cassette number setting data 107c. Details of this combination will be described below using Table 3 as an example.

  First, the temporary setting cassette number in the component cassette number setting data 107c acquired by the temporary setting value acquisition unit 105a is referred to. In the part cassette number setting data 107 c shown in FIG. 15, the provisionally set number of cassettes for the part C in the table 3 is four. Since the number of set cassettes for the part C is 5, one part cassette 312a needs to be reduced in order to reach the temporarily set cassette number 4.

  Therefore, the mounting time calculation unit 105b acquires five component cassettes 312a storing the components C from the table 3 as component cassettes to be combined (S200). In the component cassette data 107d shown in FIG. 16, the five component cassettes that store the component C are the cassette 11, the cassette 12, the cassette 15, the cassette 16, and the cassette 17. Two component cassettes arbitrarily selected from these five component cassettes are referred to as a cassette A and a cassette B.

  Then, the mounting time calculation unit 105b initializes the processed list A and the processed list B of the processed data 107e shown in FIG. 17 (S201). Note that to initialize the processed list A and the processed list B is to make the processed list A and the processed list B empty.

  If the cassette A that is not in the processed list A of the processed data 107e shown in FIG. 17 can be acquired from the five component cassettes 312a, the mounting time calculation unit 105b starts loop 2 (S202). . Furthermore, if the mounting time calculation unit 105b can acquire a cassette B that is not in the processed list B of the processed data 107e shown in FIG. 17 from the five component cassettes 312a, the mounting time calculation unit 105b starts the loop 3 (S204). . Here, since the processed list A and the processed list B are empty in the initial state, any component cassette can be acquired as the cassette A and the cassette B, and the process proceeds to the next step.

  Then, the mounting time calculation unit 105b acquires the cassette A and the cassette B, and couples the cassette B to the cassette A (S206). In FIG. 16, cassette A is cassette 11, and cassette B is cassette 12. That is, the parts stored in the cassette 12 are supplied to the cassette 11 and the cassette 12 is reduced. Then, the mounting time calculation unit 105b calculates the tact after the combination (S208).

  Next, when the mounting time determination unit 105c determines that the tact calculated by the mounting time calculation unit 105b exceeds the line tact (YES in S210), the combination is restored (S212), and the time is not exceeded. If determined (NO in S210), the coupling is performed (S214).

  When this combination is performed, the component division number setting unit 105d performs the setting as shown in the component cassette data 107d in FIG. That is, the component division number setting unit 105 d sets the cassette 12 as the combined cassette and sets the cassette after review after being combined with the cassette 11 as the cassette 11. Note that the cassette 12 is deleted from the cassette after review. Thus, by deleting the cassette 12, one component cassette can be reduced. Then, the component division number setting unit 105d sets the number of cassettes to be reset in the component cassette setting data in FIG. This reset cassette number of 4 is the number of parts division after resetting.

  Then, the mounting time calculation unit 105b adds the cassette 12 to the processed list B (S216).

  In this way, the combination with the cassette 11 (cassette A) is repeated until the cassette B that is not in the processed list B cannot be acquired or the number of component cassettes reaches the temporarily set number of cassettes (S218, S204). Note that “cannot acquire a cassette B that is not in the processed list B” means that all component cassettes that can be selected as the cassette B are added to the processed list B. Specifically, when the cassette 11 (cassette A) is coupled, the cassette 12, the cassette 15, the cassette 16, and the cassette 17 are added.

  If the cassette B that is not in the processed list B cannot be acquired or the number of component cassettes reaches the temporarily set cassette number, the mounting time calculation unit 105b ends the loop 3 (S204, S218). Then, the cassette 11 (cassette A) is added to the processed list A (S220), and the processed list B is initialized (S222).

  In this manner, the combination of cassette A and cassette B is repeated until cassette A that is not in processed list A cannot be acquired or the number of component cassettes reaches the provisional number of cassettes (S224, S202). Note that “cannot acquire a cassette A that is not in the processed list A” means that all component cassettes that can be selected as the cassette A are added to the processed list A. Specifically, cassette 11, cassette 12, cassette 15, cassette 16, and cassette 17 are added.

  In the case of the part C in the table 3 shown in FIG. 15, since the number of provisionally set cassettes is 4, the process ends when the number of part cassettes becomes 4. For example, when the number of temporarily set cassettes is 3, the parts cassette The combination of cassette A and cassette B is repeated until the number reaches 3 (S202, S204, S218, S224). In this case, when the number of component cassettes becomes 3, the reset cassette number is set to 3.

  However, when all the cassettes A and B are added to the processed list A and the processed list B when the number of component cassettes is 4, the reset number of cassettes is set to 4. That is, even if cassette A and cassette B are combined (S206) so that the number of component cassettes is 3, the line tact deteriorates (Yes in S210), and the number of component cassettes cannot be reduced to 3. The number of cassettes to be reset is set to 4.

  Information such as the number of re-set cassettes and the cassette after review is displayed on the display unit 102.

  As described above, in the present embodiment, the number of components C in the component cassette 312a of the component mounter 300 shown in FIG. 19A is reduced from five to four. Note that, as shown in FIG. 19B, the tact increased from 40 s to 55 s, but does not exceed the line tact 60 s. Therefore, the number of component cassettes can be reduced without increasing the line tact.

  In the present embodiment, the description has been made on the assumption that the number of component cassettes for one type of component is reduced by one table, such that only the component cassette storing the component C in the table 3 is reduced. A plurality of component cassettes for a plurality of types of components may be reduced with one table.

(Modification 1)
Here, a first modification of the present embodiment will be described. In the above embodiment, the cassette A and the cassette B are component cassettes arbitrarily selected from the component cassettes to be combined, but the cassette A and the cassette A and the cassette A and the cassette A and the mounting head can adsorb more components simultaneously. Cassette B may be selected. That is, the cassette A and the cassette B may be selected so that the arrangement of the component cassettes after being combined becomes an arrangement in which the mounting head can simultaneously absorb more components by one adsorption operation.

22 and 23 are diagrams for explaining an example of the mounting condition determination method according to the present modification.
FIG. 22 is a diagram showing an example in which the component cassette is arbitrarily selected and coupled.

  The number of provisionally set cassettes for component C of component mounter 300 is set to 3, and component cassettes are combined. As shown in FIG. 16, the component cassettes that store the component C are a cassette 11, a cassette 12, a cassette 15, a cassette 16, and a cassette 17.

  The cassette 12 and the cassette 15 are combined with the cassette 11 as a combination of arbitrarily selected component cassettes.

  First, the cassette 12 is coupled to the cassette 11. Then, as shown in FIG. 22B, the tact is changed from 40 s to 55 s. Next, the cassette 15 is further coupled to the cassette 11 to which the cassette 12 is coupled. Then, as shown in FIG. 22B, the tact is changed from 55 s to 65 s.

  Then, since the tact exceeds 60 s of the line tact, the cassette 15 cannot be coupled to the cassette 11. Therefore, the number of re-set cassettes is set to 4 while the temporarily set number of cassettes for part C is 3.

  FIG. 23 is a diagram showing an example in which component cassettes are combined so that the mounting head can simultaneously attract more components.

  Similarly to FIG. 22, the number of temporarily set cassettes of the component C of the component mounter 300 is set to 3, and the component cassettes are combined. Since the contents other than those described below are the same as those in the flowchart showing an example of the operation of the mounting condition determining apparatus in the present embodiment shown in FIGS. 20 and 21, the details are omitted.

  First, the mounting time calculation unit 105b selects a combination of component cassettes so that the mounting head can simultaneously pick up more components. Then, as a result of selection, the cassette 16 and the cassette 17 are coupled to the cassette 11. Note that as the mounting head sucks more components at the same time, the number of operations of suction, movement, and mounting that are repeatedly performed by the mounting head can be reduced, so that the tact becomes smaller.

  Then, the mounting time calculation unit 105 b couples the cassette 16 to the cassette 11. Then, as shown in FIG. 23 (b), the tact time is 50 s, which is smaller than when the cassette 12 shown in FIG. 22 (b) is coupled. Next, the mounting time calculation unit 105b further couples the cassette 17 to the cassette 11 to which the cassette 16 is coupled. Then, as shown in FIG. 23B, the tact is changed from 50 s to 58 s.

  As a result, the mounting time determination unit 105c determines that the tact does not exceed 60 s of the line tact. Then, the part division number setting unit 105d combines the cassette 16 and the cassette 17 with the cassette 11, and resets the part C and sets the number of cassettes to 3.

  In this way, if the component cassettes to be combined are selected so that the mounting head can simultaneously attract more components, more component cassettes can be combined. This makes it possible to reduce more extra parts cassettes without exceeding the line tact.

(Modification 2)
Here, a second modification of the present embodiment will be described. In the above embodiment, the mounting conditions are determined so as not to exceed the line tact of the component mounter 200 or the like. However, in this modified example, in the alternate component mounting machine, the waiting time for the second mounting head to mount the component while the first mounting head mounts the component is reduced. Determine the implementation conditions.

24 and 25 are diagrams for explaining an example of the mounting condition determination method according to the present modification.
The component mounter 200 or the like is an alternately mounted component mounter in which a plurality of mounting heads alternately mount components on a single board.

  FIG. 24 is a diagram illustrating a process in which the mounting head 213 a and the mounting head 213 b mount components on the substrate 20 in the alternating component mounting machine 200.

  The component mounter 200 includes a mounting unit 210a and a mounting unit 210b. Then, each of the mounting unit 210a and the mounting unit 210b adsorbs the component from the component supply unit when the other mounting head mounts the component on the substrate 20, and conversely, the other mounting head receives the component from the component supply unit. When the component is adsorbed, the components are alternately mounted on the substrate 20 so that the components are mounted on the substrate 20.

  That is, as shown in FIG. 24B, the mounting head 213b first sucks a component from the component supply unit 211b (B1) and mounts the component on the board 20 (B2). Then, while the mounting head 213b mounts the component on the substrate 20 (B2), the mounting head 213a sucks the component from the component supply unit 211a (A1).

  The mounting head 213a mounts a component on the substrate 20 (A2) after the mounting head 213b mounts the component on the substrate 20 (B2). That is, the mounting head 213a needs to wait because the next mounting operation cannot be performed until the mounting head 213b finishes mounting the components on the board 20.

  Therefore, the number of component cassettes can be reduced by combining the component cassettes 212a so as to reduce such a waiting time.

  FIG. 25 is a diagram showing a mounting process when the component cassette 212a is coupled so that the waiting time is reduced.

  As shown in FIG. 25A, the component cassette 212a is coupled so that the waiting time of the mounting head 213a is reduced.

  Then, as shown in FIG. 25 (b), the time (A1, A3, A5, etc.) for the mounting head 213a to pick up the component from the component supply unit 211a becomes longer and the waiting time becomes shorter. In this way, the number of component cassettes can be reduced by coupling the component cassettes.

  The component cassettes are coupled in this way when the tact does not exceed the line tact. That is, even if the waiting time is reduced, if the tact exceeds the line tact, the parts cassette is not coupled.

  FIG. 26 is a flowchart illustrating an example of the operation of the mounting condition determining apparatus 100 according to the present embodiment.

  First, the temporary setting value acquisition unit 105a acquires the value of the temporary setting cassette number of the component cassette number setting data 107c from the operator via the input unit 103 (S300).

  Then, the mounting time calculation unit 105b targets the stage 1 (S301), and acquires a component cassette so that the waiting time is reduced (S302). Here, the stage refers to an assembly of two mounting units included in the component mounter, and each component mounter has one stage. For example, the stage 1 refers to an assembly of the mounting unit 210a and the mounting unit 210b of the component mounter 200. In addition, acquiring the component cassette so that the waiting time is reduced means, for example, acquiring a component cassette in which a large number of components that are to be sucked in the sucking process with a waiting time are stored. The component cassettes to be acquired are component cassettes in which the number of provisionally set cassettes is smaller than the number of set cassettes in the component cassette number setting data 107c.

  Then, a component cassette coupling step is executed (S304). Here, the component cassette coupling step is a step of coupling the acquired component cassette to a component cassette that stores components of the same component type. This component cassette combining step is a step of combining component cassettes so that the number of component cassettes is the number of provisional cassettes, as in the component cassette combining step shown in FIG. Omitted.

  Next, the stage 2 is targeted (S306), and the component cassette combining step is executed in the same manner as in Table 1 (S308, S301, S302, S304).

In this way, the component cassette combining step is executed for all stages.
In this way, the number of component cassettes can be reduced by combining the component cassettes so as to reduce the waiting time without exceeding the line tact.

  In the second modification example of the present embodiment, the second modification example of the present embodiment is further performed after the above-described embodiment is performed. However, the above-described embodiment is not performed. The second modification example of the present embodiment may be performed.

  As mentioned above, although the mounting condition determination method according to the present invention has been described using the above embodiment and its modifications, the present invention is not limited to this.

  For example, in the present embodiment and its modification, the target production time is a line tact, but the target production time may be a time longer than a line tact such as a production delivery date of a product.

  Further, in the present embodiment and its modification, it is assumed that there are a plurality of component mounters on the production line. However, if the target production time is longer than the line tact, one component mounter may be used.

  Further, in the present embodiment and its modification, one or more component cassettes are combined into one component cassette. For example, the components of one component cassette store components of the same component type. It may be distributed and supplied to two or more component cassettes. Thereby, one component cassette is reduced.

  In the present embodiment and its modification, the temporary setting value acquisition unit 105a acquires the value of the number of temporary setting cassettes from the operator via the input unit 103. However, the temporary setting value acquisition unit 105a Alternatively, a value smaller than the set number of cassettes may be automatically acquired as the temporarily set number of cassettes.

  In the present embodiment and its modification, the mounting condition determination by the mounting condition determination device 100 is performed before the operation of the component mounting machine is started. The mounting conditions may be reviewed by determining the mounting conditions at 100.

  Further, in the present embodiment and its modification, the mounting conditions are determined for the alternating component mounting machine. However, in the present embodiment and the modification 1, the mounting condition is limited to the alternating component mounting machine. In addition, any component mounting machine capable of simultaneously sucking a plurality of components with the mounting head may be used.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
