  Each of these facilities is provided with a display device 98... Such as a monitor for displaying the operation status.

  FIG. 2 is a plan view showing an example of a mounting machine. As shown in the figure, the mounting machine 10 is disposed on a base 11 and conveys a printed circuit board P, a component supply unit 30 disposed on both sides of the conveyor, and above the base 11. The electronic component mounting head unit 40 is provided.

  The component supply unit 30 is provided on the upstream side and the downstream side of the conveyor 20 on the front side and the rear side, respectively. In this embodiment, a component supply unit 31 capable of mounting a plurality of component supply devices such as tape feeders side by side is provided on the front side and the rear side upstream portion, and a component supply device such as a pallet is stacked on the rear side downstream portion. A tray-type component supply unit 32 that can be attached is provided. The components supplied from these component supply units 30 can be picked up by the head unit 40. The mounting machine 10 is a facility to which a plurality of component supply devices can be attached.

  The head unit 40 is movable in a region extending between the component supply unit 30 and the mounting position on the printed circuit board P so that components can be picked up from the component supply unit 30 and mounted on the printed circuit board P. Specifically, the head unit 40 is supported by a head unit support member 42 extending in the X axis direction (substrate transport direction of the conveyor 20) so as to be movable in the X axis direction. The guide rails 43, 43 extending in the Y-axis direction (a direction orthogonal to the X-axis in the horizontal plane) are supported so as to be movable in the Y-axis direction. The head unit 40 is driven in the X axis direction by the X axis motor 44 via the ball screw 45, and the head unit support member 42 is driven in the Y axis direction by the Y axis motor 46 via the ball screw 47. To be done.

  In addition, a plurality of heads 41 are mounted on the head unit 40 side by side in the X-axis direction. Each head 41 is driven in the vertical direction (Z-axis direction) by an elevating mechanism using a Z-axis motor as a drive source, and is driven in the rotation direction (R-axis direction) by a rotation drive mechanism using an R-axis motor as a drive source. It has come to be.

  At the tip of each head 41, a suction nozzle for picking up electronic components and mounting them on the substrate is provided. Each nozzle is supplied with a negative pressure from a negative pressure means (not shown) at the time of component suction, and can suck the electronic component with a suction force by the negative pressure.

  In FIG. 1, reference numeral 12 denotes a camera, which captures an image of the state of a component sucked by the head unit 40 so that a positional deviation of the component can be detected.

  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 bar code reader 13 connected to the machine 10, the feeder ID and the like can be known. This bar code reader 13 functions as an input means for inputting identification information for identifying the feeder 35 which is a component supply device.

  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 connected to the machine 10, the pallet ID and the like can be known. The barcode reader 13 functions as an input unit for inputting identification information for identifying the pallet 36 which is a component supply device.

  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, from the viewpoint of improving the production efficiency of the entire mounting line 90, which mounting machine 10 is assigned to each mounting operation is determined by a known optimization method, and is assigned to each mounting machine. A procedure for performing the mounting work is created as an initial production program. In this production program, for each mounting operation, in addition to data on the type of component to be mounted and the mounting coordinate position on the board, etc., a component supply device that supplies components for each mounting operation is attached to which mounting machine. It also has information regarding the arrangement of the component supply device, which is to be attached to the position.

  On the other hand, if production is to be performed based on such a preset production program, a setup operation for attaching the component supply device to the installation position specified by the production program must be performed, which is a problem in setup workability. There is room for improvement.

  Therefore, in the mounting line 90 of this embodiment, a mounting operation for mounting various components on the production target board is performed according to the arrangement of the component supply devices currently attached to any mounting machine of the mounting line 90. The initial production program can be changed as appropriate.

  Specifically, the control device 99 of each mounting machine extracts mounting work that cannot be executed by the component supply device attached to the mounting work assigned to itself. Then, the arrangement information of the current component supply device in the other mounting machine 10 is acquired via the network in the mounting line, and another mounting machine 10 that can be replaced by a mounting operation that cannot be performed by itself is searched. . If another mounting machine 10 is found in this way, the mounting work information (mounting data) that the user wants to replace is sent to the other mounting machine 10, and the mounting work is moved by skipping this mounting work. The mounting work is assigned in accordance with the arrangement of the component supply devices.

  Further, after the mounting work is assigned to each mounting machine 10, the control device 99 of each mounting machine 10 takes out the position on the board, the part to be mounted, and this part corresponding to the assigned mounting work. A set of data including a component supply device, a head 41 for conveying the components, and a mounting order is formed, and this data is stacked to reconstruct the production program. That is, this one set of data corresponds to the mounting work assigned to each component supply apparatus. When a set of data is formed, a component supply device for taking out a component is first selected from those already mounted on the mounting machine 10, recorded together with the mounting position on the data, and if there is no mounted, The necessary component supply device is recorded on the data as the component supply device to be installed.

  The equipment to which a plurality of component supply devices can be attached is not limited to the mounting machine 10, and is equipped with a feeder cart that can be moved by mounting a large number of tape feeders 35, a tray supply device that stores a large number of pallets 36, and bare chips. There are feeders that can supply multiple wafers. These facilities are mounted on the mounting machine 10, connected, or arranged at a predetermined vicinity. The head 41 of the mounting machine 10 picks up components from predetermined component supply devices of these facilities, conveys them onto the board, and mounts them at predetermined positions.

  As described above, in this embodiment, the control devices 99 of the respective mounting machines 10 cooperate with each other as mounting work allocating means for allocating the mounting work on the production target board to each component supply device in accordance with the arrangement of each facility. It is supposed to function. It should be noted that the mounting work allocating means may function alone or in combination with the control device 99 of a device other than the mounting machine 10.

  In this way, if a component supply device that supplies the necessary components is attached to any equipment on the mounting line 90, the operation of attaching, removing, and moving such a component supply device by the operator is reduced. Therefore, the setup work can be facilitated. For example, at the time of actual setup work, a component supply device for the board that was produced immediately before is already attached to each facility, so that excellent setup workability can be obtained by using this. .

  Only the parts that are not attached to any equipment on the mounting line 90 among necessary parts are dealt with by performing a setup operation for attaching the parts supply device to any equipment on the mounting line 90 by an operator or the like. It has become.

  However, if a mounting operation is assigned to each component supply device according to the component supply device currently installed in each facility in this way, the type of component supply device installed in each facility and the production target board Depending on the combination of 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, when a mounting machine that causes a bottleneck whose 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, the arrangement of the component supply device attached to itself, the arrangement of the component supply device attached to the external equipment for supplying components to the mounting machine, and the mounting machine are assigned. Depending on the combination with the mounting work, there is a possibility that high production efficiency may not be obtained, for example, the head moving distance in each mounting work becomes long, or there are few opportunities to simultaneously suck components with the head.

  Furthermore, depending on the position where the component supply device is attached, there may be a case where the component cannot be taken out by the head.

  Therefore, in the present invention, when an operator or the like intends to install the component supply device to each facility on the mounting line as a setup operation, a non-installable position where the component supply device to be installed should not be installed or a recommended installation position where installation is recommended Is notified to an operator or the like, so that it is possible to prevent the arrangement of a component supply device that may cause a decrease in productivity.

  Hereinafter, a case where a component supply device is attached to each mounting machine itself will be described as an example.

  The non-mountable position is a position where it is determined that the component supply device should not be mounted. For example, a position that does not contribute to the mounting work, such as being unable to take out the component even if it is mounted, or a position that hinders other mounting work Or a position that hinders setup workability.

  In this embodiment, specifically, (1) a position that can be adsorbed only by a head that cannot be equipped with a nozzle that handles components supplied by the component supply device, and (2) interference with an already-installed component supply device (already A position that requires removal of the attached component supply device), and (3) a position that is reserved for attachment of another component supply device are set as non-attachable positions.

  In this embodiment, the mounting impossible position is calculated by the control means 99 of each mounting machine 10, and the mounting impossible position is displayed and notified on the display device 98 provided in each mounting machine. The display device 98 functions as an unmountable position notifying means.

  The recommended mounting position is a position that is preferably mounted from the viewpoint of the productivity of the entire mounting line and the equipment to which the component supply device is mounted.

  In this embodiment, the recommended mounting position is advantageous in productivity, such as (1) designated by the production program, (2) close to the component mounting position on the board and the recognition camera, and (3) each mounting line. It is set by comprehensively judging various conditions such as the ability to equalize the load balance between facilities, (4) no component supply device already installed, and the like.

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

  Each mounting machine intermittently transmits (broadcasts) its own load information (own equipment load information) due to the mounting work required for the production program to all other mounting machines. Each mounting machine receives other equipment load information transmitted from other mounting machines. The communication means provided in the control device 99 of each mounting machine functions as a transmitting means for transmitting the load information of each mounting machine to the outside.

  Further, the network in the mounting line 90 is connected to a host computer (host PC) composed of a personal computer or the like that comprehensively manages the operation of the entire mounting line, and each mounting machine is attached to each component supply device and to it. It is possible to obtain shared information such as the type of parts being used.

  In this way, each mounting machine obtains the load information of the other mounting machines, and in consideration of the balance with the load state of the other mounting machines, the recommended mounting position of the component supply device to be mounted on itself is determined. Can be calculated.

  FIG. 5 is an example of a data table used when determining the load of each mounting machine. As shown in FIG. 6A, the production program use point table shows the type of board (product type A, type A) for each mounting machine (mounting machine A, mounting machine B, mounting machine C,...). The mounting work assigned in the production program corresponding to the product type B ...) is stored for each type of component (part A, part B, part C ...). In addition, if the allocation of the mounting work is changed according to the current arrangement of the component supply devices, the used point count for each production program is corrected at any time in order to calculate the current load.

  In addition, as shown in FIG. 5B, in the process capacity ratio table for each mounter, a reference component (as a value indicating the compatibility between each mounter (mounter A, mounter B...) And the component type) In this example, the mounting capability rate for the case of mounting the component A) is stored for each component type (component A, component B, component C,...). For example, the mounting machine A has a capability rate of 80% for the component B, and it can be seen that only 80% of the speed is obtained as compared with the case where the component A is mounted. This capacity rate is fed back from production results and updated as needed.

  Further, as shown in FIG. 5C, the capacity (speed) of each mounting machine (mounting machine A, mounting machine B,...) Is stored in the process capacity table for each mounting machine. For example, it can be seen that the mounting machine A has the capability of mounting 20000 components per hour (component A in this example).

（点数／能力率）は各種類の部品を基準とする部品（部品Ａ）に換算した場合の部品点数（個数）であり、これを全種類の部品について合計して、基準とする部品（部品Ａ）１個あたりの実装に要する時間を示す（３６００／実装機工程能力）を乗じることにより、各実装機におけるサイクルタイム（推定生産時間）として負荷が求められる。 Based on such data, the load on each mounting machine can be obtained by, for example, the following equation.

(Score / Performance) is the number of parts (number) when converted to a part (part A) based on each type of part. This is the sum of all types of parts and is used as a reference part (part A) A load is obtained as a cycle time (estimated production time) in each mounting machine by multiplying (3600 / mounting machine process capability) indicating the time required for one mounting.

  In this embodiment, the load is calculated by the control means of each mounting machine itself. In addition, the control unit 99 of each mounting machine obtains load information of the other mounting machines, and takes into account the balance with the load state of the other mounting machines, etc. The recommended installation position of the supply device is calculated. Further, the calculated recommended mounting position is notified by being displayed on the display device 98 provided in each mounting machine. That is, the control means 99 and the display device 98 function as recommended attachment position notification means.

  FIG. 6 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. 7 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 a so-called setup operation is performed by the operator for the component supply devices that supply the missing components. .

  As shown in the figure, during the setup work, each mounting machine intermittently communicates the current load information in the mounting machine to each other (step S10).

  In this state, as a setup operation, an operator (operator) who intends to attach a component supply device to any of the mounting machines 10 uses a bar of the mounting machine 10 to attach identification information (barcode) of the component supply device. It is read by the code reader 13, and the mounting machine 10 side is inquired about the setup work of the component supply apparatus (step S12). If there is no inquiry (NO in step S14), each mounter 10 returns to load information mutual transmission (step S10).

  If there is an inquiry from the operator (YES in step S14), the mounting machine 10 first calculates an unmountable position for the component supply device (step S16). Details of the non-attachable position calculation will be described later.

  Subsequently, the mounting machine calculates a recommended mounting position for the component supply device (step S18). Details of this recommended mounting position calculation will also be described later.

  If there is no recommended mounting position as a result of the recommended mounting position calculation (NO in step S20), the operator removes the parts currently attached to each facility so that the recommended mounting position is generated (step S22), and re-installs. The process returns to the recommended position calculation (step S18).

  On the other hand, if there is a recommended mounting position (YES in step S20), the worker mounts the component supply device at any of the recommended mounting positions notified. Then, the component supply device attached on the mounting machine side and its position are confirmed, and if it is attached to a non-attachable position (YES in step S26), an error display is performed (step S28).

  If the attached position is not a non-mountable position (NO in step S26), a production program for moving the mounting operation between mounting machines or within the mounting machine as necessary according to the position where the component supply device is mounted. Is rewritten (step S30), and the current load information mutual communication is returned (step S10).

  Next, an example of non-mountable position calculation will be described with reference to the flowchart of FIG. In calculating the unmountable position, the component information of the component supplied by the component supply device to be mounted is acquired by the control means 99 of the mounting machine 10 on which the component supply device is to be mounted by the operator (step). S40). The component information includes information such as a nozzle for sucking the component.

  Next, among the heads provided in the head unit 40, a head to which a nozzle for sucking this component can be mounted is extracted (step S42). If there is no corresponding head (YES in step S44), the mounting machine 10 cannot perform the mounting operation of the component and cannot be mounted on the mounting machine 10, so that this is notified by an error display (step S46). Then, the installation impossible position calculation ends.

  If there is a corresponding head (NO in step S44), the movable range of the head is calculated (step S48), and the set position outside the movable range (attachment position of the component supply device) is extracted (step S50). Further, the attachable position and width are extracted as attributes of the component supply device (step S52).

  Based on these pieces of information, a set position that cannot be attached is obtained (step S54). Specifically, for example, a position that can be adsorbed only by a head that cannot be equipped with a nozzle that handles the component is an unmountable position. Further, a position that interferes with a component supply device that has already been attached is also set as a non-attachable position. This can also be applied to the case where a component supply device is already attached to an adjacent set position according to the width of the component supply device. In addition, there is a component supply device that can be attached only to the set position, and a set position reserved for attaching the component supply device is also set as a non-attachable position.

  If there is no unmountable position (NO in step S54), the unmountable position calculation is terminated as it is, and if there is a nonmountable position (YES in step S54), the unmountable position is displayed (step S56) and the process is terminated. .

  FIG. 10 is an example of a screen displaying the unmountable positions. As shown in the figure, for the component supply device (component PARTXX6) to be mounted, the symbol portion indicating the component mounting positions (set positions) 1 to 8 of the lower left component supply unit is shaded in dark color, for example. It is displayed that these positions are non-mountable positions.

  Next, an example of recommended mounting position calculation will be described with reference to the flowchart of FIG. In this recommended mounting position calculation, the recommended mounting position in the mounting machine and the recommended mounting position in consideration of the load balance with other mounting machines are calculated in parallel.

  The calculation of the recommended mounting position in the mounting machine is based on the assumption that the mountable position and width of the component supply device to be mounted are extracted in step S52 of the unmountable position calculation described above. Then, a vacant position that does not interfere with the already mounted component supply apparatus is extracted (step S70). If there is no vacant position (NO in step S72), is there a removable part that is not used in the mounting machine? It is determined whether or not (step S74). If there is a removable component (YES in step S74), the removable component is displayed (step S75). If there is no removable component (NO in step S74), the component supply device is attached to the mounting machine. An error message indicating that it is not possible is displayed (step S76), and this recommended mounting position calculation is terminated. When a removable part is displayed, the recommended attachment position calculation is repeated again by the operator removing the part (see step S22 in FIG. 7). In addition, when it cannot be attached to the mounting machine, the worker tries to attach to another mounting machine.

  On the other hand, if there is a vacant position that does not interfere with the already installed parts supply device (YES in step S72), it is determined whether the vacant position includes the set position specified in the production program (step S78). If so (YES in step S78), the set position specified in the production program is displayed as the recommended mounting position for itself (step S80), and the recommended mounting position calculation is terminated.

  If the vacant position is not the set position designated by the production program (NO in step S78), the flow merges with the load balance calculation flow with other mounting machines.

  In this load balance calculation with other mounting machines (step S82), another mounting machine with a lower load than itself is searched (step S84). If there is no such other mounting machine (no step S84), Using the above-mentioned empty positions where the component supply device can be attached as set position candidates, a position advantageous for productivity is calculated from these positions (step S86). Then, a position advantageous for productivity is displayed as its recommended installation position (step S80), and the recommended installation position calculation is terminated.

  If there is another mounting machine having a lower load than the mounting machine (in step S84), it is determined whether or not the component supply device can be attached to the other mounting machine (step S88). The productivity advantageous position is calculated from the set position candidates of the mounting machine (step S86), and this is displayed (step S80), and the recommended mounting position calculation is terminated.

  If another mounting machine having a lower load than the mounting machine can attach the component supply apparatus (step S88), the component supply apparatus should be attached to the other mounting machine from the mounting machine. Installation instruction display to the machine is performed (step S90), and the recommended installation position calculation is terminated. In addition, if an operator who has received an instruction to attach to another mounting machine reads the identification information of the component supplying apparatus with a barcode reader of another mounting machine in order to attach the component supplying apparatus to the other mounting machine, The recommended mounting position is displayed on the display device of another mounting machine.

  FIG. 11 is an example of a screen displaying recommended mounting positions. As shown in the figure, for the component supply device (parts PARTXX6) to be installed, the component attachment position (set position) No. 13 (F013) of the lower left component supply unit and the component attachment of the lower right component supply unit The symbol portion indicating the position (set position) No. 26 is displayed, for example, in a bright blinking state, and expresses that these positions are recommended mounting positions. In the work instruction column, since it becomes complicated when a plurality of recommended mounting positions are displayed, for example, only F013 having a smaller mounting position number is displayed.

  As described above, according to the mounting operation line according to the present embodiment, the mounting impossible position is notified about the component supply apparatus to be installed, and thus the productivity is lowered due to the mounting of the component supply apparatus at the non-mountable position during setup work. Can be prevented.

  In addition, since the recommended mounting position is notified for the component supply apparatus to be mounted, it is possible to increase the possibility that each component supply apparatus is mounted at the recommended mounting position at the time of setup work, and to reduce the decrease in productivity. On the other hand, if the component supply device is attached to any of the attachment positions, the mounting work can be assigned according to the attached position, so that the setup workability can be improved.

  In addition, since such recommended mounting positions are set based on the work load balance of each facility, the work load balance of each facility can be equalized, and the productivity of the entire mounting line can be improved.

  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-described embodiment, the set position where the already attached parts must be removed is set as the non-attachable position, but only the set positions where it is impossible to install or meaningless because the parts cannot be taken out are considered as non-attachable positions. For example, the reference for setting the unmountable position can be set as appropriate.

  Further, in the above embodiment, the setting is given priority to the production program designated position as the recommended installation position, but the recommended installation position such as determining the recommended installation position with priority given to equalization of the load balance between the respective facilities. The standard to do can be set suitably. For example, even if the production program designation position is an empty position, the recommended installation position may be set with priority on equipment with a smaller load.

  In the above embodiment, when other equipment is recommended as the recommended installation position, the other equipment having the recommended installation position is notified. However, the recommended installation position in the other equipment may be notified at the same time.

  Moreover, in the said embodiment, although the input means which inputs the identification information of a component supply apparatus was comprised with the barcode reader with which a mounting machine is provided, if it can input identification information, it will not be limited to this. For example, an operator or the like may input the identification information (ID) of the component supply apparatus using a management computer or a keyboard connected to a computer that controls each facility as input means.

  In the above embodiment, the control means of each facility (mounting machine) on the mounting line calculates the mounting impossible position and the recommended mounting position. For example, a management computer that performs overall control of the mounting line performs these functions. You may make it fulfill.

  In the above embodiment, the control means of each facility (mounting machine) on the mounting line functions as the mounting work assignment means for assigning the mounting work to each component supply device. A computer, a control means (computer) of a specific facility, or the like may function as the mounting work assignment means, and each mounting machine may execute the mounting work thus assigned.

  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.
