Description

The present invention relates to a technical field of a working machine arranged in a board production line for mounting electronic components on a board. More specifically, the present invention relates to an exchange support apparatus that assists an operator in exchanging components that can be exchanged at an installation position of a work machine.

As a working machine for producing a substrate on which a large number of electronic components are mounted, there are a solder printer, a component mounting machine, a reflow furnace, a board inspection machine, and the like. In many cases, these work machines are connected to construct a substrate production line. Furthermore, a component mounting line may be configured by arranging a plurality of component mounting machines in a line. This type of component mounter generally includes a component supply device and a component transfer device. A feeder device, which is a typical component supply device, includes a drive mechanism that sequentially draws out tapes containing electronic components in a row. Since the drive mechanism has a movable part, it is recommended that the feeder device be regularly maintained. In addition, the component transfer apparatus includes a mounting nozzle and a mounting head for picking up an electronic component and mounting it on a substrate. It is recommended that the mounting nozzle and the mounting head be regularly maintained. As for a solder printer, it is recommended that regular maintenance be performed, such as a squeegee.

The feeder device, the mounting nozzle, the mounting head, and the like described above are components that are exchangeably mounted at the mounting position of the component mounting machine and operate. In order to increase production efficiency, many of these components are prepared and stored in advance, and in many cases, the components are appropriately replaced according to the type of substrate to be produced. In addition, maintenance of these components is carried out after being removed from the mounting position of the component mounter. At this time, the production interruption time can be shortened by installing another component that has undergone maintenance. Patent Document 1 and Patent Document 2 disclose a technical example for managing a maintenance execution time (maintenance time) for components of a component mounting machine.

The electronic circuit component mounter maintenance method disclosed in Patent Document 1 is characterized in that maintenance of components of a plurality of electronic circuit component mounters installed in a plurality of factories is concentrated. According to this, maintenance can be performed efficiently, and productivity is improved by reducing maintenance costs. Further, the embodiment discloses that a feeder is identified by a feeder ID (identification code) of a barcode provided in a plurality of feeders (component supply devices). Also, if the number of parts supply for a feeder exceeds the set number of times, or if the number of occurrences of supply errors exceeds the set number of times, it is determined that the feeder cannot withstand use and needs maintenance. Yes.

The maintenance work support system for a component mounting system disclosed in Patent Document 2 by the applicant of the present application includes a maintenance data holding unit and a maintenance work plan creation unit. The maintenance data holding unit holds maintenance data including maintenance work items for the maintenance targets of the plurality of mounting-related work machines and their execution frequencies. The maintenance work plan creation unit creates a maintenance work plan to be maintained based on the maintenance data. According to this, since a plurality of mounting-related work machines are targeted, there is convenience unlike a system that targets one mounting-related working machine of the prior art. Furthermore, it is possible to perform maintenance work with high efficiency by preventing forgetting maintenance and excessive maintenance.

By the way, the technique of patent document 1 and patent document 2 is preferable at the point which guides the maintenance time of the component of a component mounting machine to an operator. However, simply performing maintenance according to the guidance may reduce maintenance efficiency. For example, if a plurality of components are installed at random without considering the maintenance time, the maintenance time comes frequently during the lot production, and the production efficiency is lowered.

Patent Document 1 and Patent Document 2 do not disclose a method for supporting selection of a newly equipped component when changing the type of substrate to be produced. Since the next maintenance time of each component can be predicted from various information, the efficiency of production can be expected by selecting the component considering this.

The present invention has been made in view of the above-mentioned problems of the background art, and by presenting candidate components to be newly equipped in consideration of the maintenance timing of the components to be equipped on the work machine, the production efficiency can be improved. Providing an exchange support device that contributes to improvement is an issue to be solved.

According to a first aspect of the present invention, there is provided an exchange support apparatus for exchanging a component that is installed in an exchangeable manner at an equipment position of a work machine disposed on a board production line for mounting electronic components on a board. A replacement support apparatus for supporting, including a production job data storage unit that stores production job data corresponding to a type of a board to be produced, including operation frequency information related to an operation frequency of the component mounted at the equipment position; For each of the plurality of component elements, identification information for identifying the component element, actual operation number information regarding the number of operations since the previous maintenance performed on the component element, and maintenance frequency for the component element A component information storage unit that stores component information associated with maintenance frequency information, and the production job data storage unit stores the component information. Based on the production job data and the component information stored in the component information storage unit, the maintenance time is reached before the production by the production job data is completed for each of the plurality of components. A determination unit that determines whether or not, and an output unit that outputs information indicating a component for which the determination unit has determined that the maintenance time has not been reached before the production based on the production job data is completed. .

According to this, an output part outputs the information which shows the component judged that the maintenance time is not reached before the production by production job data is completed. Therefore, the operator can equip the equipment position with the component according to the output in consideration of the maintenance time, and the production efficiency is improved.

It is a figure explaining the exchange assistance apparatus of the component mounting machine of embodiment. It is a figure of the sequence flow explaining the operation | movement of the replacement | exchange assistance apparatus of the component mounting machine of embodiment, and an operator's work content. It is explanatory drawing of the 3rd example which illustrates the function of a guide part in the exchange assistance apparatus of the component mounting machine of embodiment.

A working machine replacement support apparatus 1 according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating a replacement support device 1 for a component mounter according to an embodiment. The exchange support apparatus 1 of the embodiment is configured to be incorporated in a board production line. In addition to the four first to fourth component mounting machines 31 to 34 shown in FIG. 1, the board production line includes a solder printing machine (not shown), a solder inspection machine, a board appearance inspection machine, and the like. Configured. In order to control the overall operation of the board production line, a host system 2 is provided. The component mounter replacement support apparatus 1 according to the embodiment is realized by including a maintenance management program executed by the host system 2. First, the overall configuration of the substrate production line will be described.

The four first to fourth component mounting machines 31 to 34 are modular machines of the same type, and are lined up to configure the component mounting line 3. A board | substrate is carried in to the 1st component mounting machine 31 from a solder inspection machine, and a predetermined electronic component is mounted. Thereafter, the board is sequentially conveyed to the second to fourth component mounting machines 32 to 34, each of which is mounted with a predetermined electronic component, and subsequently conveyed to the board appearance inspection machine. Each of the component mounting machines 31 to 34 exchanges various data with the host system 2 connected for communication. The number of component mounting machines 31 to 34 is not limited to four, and may be one or five or more. Each of the component mounters 31 to 34 includes a substrate transfer device, a plurality of feeder devices 4, a component transfer device, and a monitor device 61, respectively. The substrate transfer device carries in and out the substrate and positions the substrate.

Each of the plurality of feeder devices 4 is a feeder-type component supply device, and sequentially supplies a plurality of electronic components to a predetermined supply position. The feeder device 4 is an example of a component. Each feeder device 4 holds a reel in a reel holding unit (not shown in FIG. 1). The reel is wound with a tape containing a large number of electronic components in a row. Each feeder device 4 includes a drive mechanism that feeds a tape and sequentially sets electronic components to a supply position. The plurality of feeder apparatuses 4 are respectively inserted into a plurality of slots (equipment positions) formed in parallel with the upper surface of the mounting table of each of the component mounting machines 31 to 34, and are installed in a replaceable manner. Each feeder device 4 can be installed in any slot position of any mounting table of the four component mounters 31 to 34. In other words, the slot positions of the four component mounters 31 to 34 are compatible. have.

Each feeder device 4 is provided with a feeder identification code for identifying an individual. Each reel is assigned a device code for identifying the component type of the electronic component. In order to read at least one of the feeder identification code and the device code, the component mounters 31 to 34 are provided with code readers (not shown). A control unit (not shown) of the component mounters 31 to 34 recognizes a feeder identification code via a communication function with the feeder device 4 or a code reader. Thereby, the control part of the component mounting machines 31-34 grasps | ascertains the individual feeder apparatus 4 equipped with the slot position.

Moreover, the control part of the component mounting machines 31-34 recognizes a device code via a code reader. Thereby, the control part of the component mounting machines 31-34 shows the correspondence between the device code representing the component type of the electronic component accommodated in the reel and the feeder identification code of the feeder device 4 holding the reel. To grasp. The feeder identification code and device code data are communicated and transmitted to the host system 2 for sharing.

The drive mechanism of the feeder device 4 tends to deteriorate in performance with an increase in the actual operation number of times when the tape is fed and the electronic components are supplied, that is, the actual feeder feed number Nm. For this reason, it is recommended that maintenance of the feeder device 4 be performed at the time when electronic parts are supplied for a predetermined prescribed feeder feed number Nk. The prescribed feeder feed number Nk is the upper limit value of the number of operations recommended during the maintenance interval, and corresponds to the prescribed number of operations information of the present invention. Maintenance items of the feeder device 4 include, for example, inspection and cleaning of the drive mechanism and supply of lubricating oil to the movable part.

The component transfer device receives an electronic component from each supply position of the plurality of feeder devices 4 equipped, and mounts the electronic component at a designated position on the substrate positioned by the substrate transport device. The component transfer apparatus includes an XY axis drive mechanism, a mounting head 5, and a mounting nozzle. The XY axis drive mechanism drives the mounting head 5 reciprocally between the feeder device 4 and the substrate using, for example, a screw feed mechanism or a linear motor as a drive source. The mounting head 5 is replaceably mounted on a movable member (equipment position) driven in two horizontal axes by an XY axis driving mechanism. In the present embodiment, the number of mounting heads 5 provided in one component mounting machine 31 to 34 is one (single head structure). However, the present invention is not limited to this, and one mounting machine may be equipped with two mounting heads (twin head structure).

The mounting head 5 is roughly divided into a single nozzle head and a multi-nozzle head. The mounting head 5 is an example of a component. The single nozzle head holds one mounting nozzle on the lower surface. The multi-nozzle head holds a plurality of mounting nozzles at equal intervals on the circumference of the lower surface. The mounting nozzle picks up and picks up the electronic component using negative pressure and eliminates the negative pressure at a specified position on the substrate to mount the electronic component. The mounting head 5 and the mounting nozzle are compatible among the four component mounting machines 31-34. Each mounting head 5 is provided with a head identification code for identifying an individual. The control units of the component mounters 31 to 34 recognize the head identification code by the communication function with the mounting head 5. Thereby, the control part of the component mounting machines 31-34 grasps | ascertains the individual mounting head 5 equipped. The data of the head identification code is communicated to the host system 2 and shared.

The mounting head 5 has a Z-axis drive mechanism that drives the mounting nozzle held up and down, and a θ-axis drive mechanism that rotationally drives the mounting nozzle. Furthermore, the multi-nozzle head of the mounting head 5 has an R-axis drive mechanism that rotationally drives a plurality of mounting nozzles on the circumference. The mounting head 5 has an air pressure control mechanism that generates and controls negative pressure. The performance of the Z-axis drive mechanism, the θ-axis drive mechanism, the R-axis drive mechanism, and the air pressure control mechanism tends to decrease with an increase in the number of actual operations in which electronic components are mounted, that is, the actual number of shots Mm. For this reason, it is recommended that maintenance of the mounting head 5 be performed at the time when electronic components are mounted for a predetermined number of shots Mk. The prescribed shot number Mk is the upper limit value of the number of operations recommended during the maintenance interval, and corresponds to the prescribed number of operations information of the present invention. Maintenance items for the mounting head 5 and the mounting nozzle include, for example, inspection and cleaning of the drive mechanism, supply of lubricating oil to the movable part, and cleaning of the interior of the pneumatic piping.

Examples of the feeder identification code, device code, and head identification code include a bar code and a QR code (registered trademark). Naturally, the code reader is a device that can read a barcode, a QR code (registered trademark), or the like. Each feeder device 4 individually manages the past operation history, current state, maintenance time, and the like using the feeder identification code, and grasps the component type of the reel currently held using the device code. In addition, each mounting head 5 individually manages the past operation history, the current state, the maintenance time, and the like using the head identification code.

The monitor device 61 is disposed on the upper front side of each of the component mounting machines 31 to 34. The monitor device 61 displays a part of production job data, which will be described later, the operation state of the component mounters 31 to 34, and the like for the worker. The monitor device 61 is provided with an input unit for an operator to perform an input operation. The monitor device 61 also operates as an output unit and a guide unit 13 of the exchange support device 1 described later.

The host system 2 controls the overall operation of the board production line by executing a predetermined production program. The host system 2 operates as the exchange support apparatus 1 according to the embodiment by executing a predetermined maintenance management program. The host system 2 is composed of a general computer device that includes a central processing unit (CPU), a storage unit, an input unit, an output unit, and the like. The host system 2 is communicatively connected not only to the four component mounters 31 to 34 but also to a solder printing machine, a solder inspection machine, and a board appearance inspection machine (not shown). The host system 2 holds a plurality of types of production job data corresponding to the types of substrates to be produced in the storage unit. The production job data includes design information, production information, and inspection information of the board to be produced.

The design information includes information such as the size of the board, the position of the paste solder printed on the board, the type and quantity of electronic components mounted on the board, and the designated position where the electronic parts are mounted. The production information includes information that assigns component types of electronic components to the four component mounters 31 to 34 and assigns them to the slot positions, information that manages operations when the electronic components are picked up and mounted, and the like. In many cases, the production information includes a scheduled production number of boards and a production completion scheduled time. The inspection information includes information such as an imaging method when imaging and inspecting the substrate, a processing method of an image obtained by imaging, and pass / fail judgment criteria.

The host system 2 communicates and transmits a part of necessary production job data to each work machine constituting the board production line in a timely manner when necessary. In addition, the host system 2 acquires data regarding the operation status from each work machine via communication transmission. As a result, the host system 2 monitors the operation status of each work machine, the production progress status, and the like. As an index of the operation status, time required for mounting a specified number of electronic components on one board by each of the component mounting machines 31 to 34, that is, cycle times Tc1 to Tc4 (see arrow R1 in FIG. 1) is illustrated. it can. The cycle times Tc1 to Tc4 are measured every time the component mounters 31 to 34 are operated, and are communicated and transmitted to the host system 2 as indicated by an arrow R1 in FIG. In addition, as an indicator of the progress status, the production record number of substrates that have been produced can be exemplified.

The head maintenance device 7 is often arranged on the same floor as the component mounting machines 31 to 34, but the arrangement location is not particularly limited. The head maintenance device 7 performs maintenance of the mounting head 5 that is loaded and set by the operator. The head maintenance device 7 displays maintenance information including the head identification code of the mounting head 5 that has performed maintenance and the maintenance result on the display panel 71 at the upper front. The head maintenance device 7 communicates and transmits maintenance information to the host system 2 as indicated by an arrow R2 in FIG. The maintenance result is normally “good”, but may rarely become “bad” when the performance of the mounting head 5 cannot be sufficiently recovered.

The storage 8 is often arranged on the same floor as the component mounting machines 31 to 34, but the arrangement location is not particularly limited. The storage 8 is provided for storing a large number of feeder devices 4 and mounting heads 5 that are not equipped in the component mounting machines 31 to 34. The storage 8 does not necessarily need to be a warehouse closed by a housing, and may be a storage space partitioned in a floor, for example. A monitor device 65 is disposed inside the storage 8 or near the door. The monitor device 65 is communicatively connected to the host system 2. The monitor device 65 is provided with an input unit for an operator to perform an input operation. The monitor device 65 operates as an output unit and a guide unit 13 of the exchange support device 1 described later.

Next, a description will be given of the exchange support apparatus 1 according to the embodiment realized using the maintenance management program of the host system 2. The exchange support apparatus 1 includes a remaining operation number calculation unit 11, an operation frequency grasping unit 12, a guide unit 13, and an operation time management unit 14. Note that the present invention is not limited to this embodiment, and the maintenance management device 1 may be configured using a computer device separate from the host system 2.

The remaining operation number calculation unit 11 calculates the remaining feeder feed number Nr for each feeder device 4 based on the specified feeder feed number Nk and the actual feeder feed number Nm. Specifically, the remaining operation number calculation unit 11 calculates the remaining feeder feed number Nr by subtracting the actual feeder feed number Nm from the specified feeder feed number Nk. The remaining feeder feed number Nr means the number of remaining operations recommended until the next maintenance. The prescribed feeder feed number Nk is a fixed constant, and is input and set in advance from the input unit of the host system 2 to the storage unit. Depending on the type and structure of the feeder device 4, the prescribed feeder feed number Nk may be different.

On the other hand, the actual feeder feeding number Nm is a variable that is set to an initial value when the feeder device 4 is maintained and increases each time it operates. The initial value is normally zero, but is not limited to this. The operator inputs the feeder identification code of the feeder apparatus 4 that has performed maintenance from the input unit of the host system 2. Then, the remaining operation number calculation unit 11 sets the actual feeder feeding number Nm corresponding to the feeder identification code as an initial value after the maintenance is performed, and stores it in the storage unit.

The feeder device 4 is installed in any one of the slot positions of any one of the component mounting machines 31 to 34 to supply electronic components. Then, as indicated by an arrow R1 in FIG. 1, the remaining operation number calculation unit 11 acquires the actual feeder feed number Nm of the feeder device 4 from the component mounters 31 to 34 together with the feeder identification code. In this case, the remaining operation number calculation unit 11 may directly acquire numerical information of the actual feeder feed number Nm. Alternatively, the remaining operation number calculation unit 11 may acquire information (for example, pulse signal information) indicating that the feeder device 4 has been operated each time, perform a count-up process, and obtain the actual feeder feed number Nm. The remaining operation number calculation unit 11 stores the feeder identification code of each feeder device 4 and the remaining feeder feed number Nr obtained by the calculation as a set. Note that the actual feeder feed number Nm and the remaining feeder feed number Nr do not change during the period when the feeder device 4 is removed from the component mounters 31 to 34.

Further, the remaining operation number calculation unit 11 calculates the remaining shot number Mr for each mounting head 5 based on the specified shot number Mk and the actual shot number Mm. Specifically, the remaining operation number calculation unit 11 calculates the remaining shot number Mr by subtracting the actual shot number Mm from the specified shot number Mk. The remaining shot number Mr means the number of remaining operations recommended until the next maintenance. The specified number of shots Mk is a fixed constant, and is input and set in advance from the input unit of the host system 2 to the storage unit. Depending on the type and structure of the mounting head 5, the prescribed shot number Mk may differ.

On the other hand, the actual shot number Mm is a variable that is set to an initial value at the time when the mounting head 5 is maintained and increases each time the operation is performed. The initial value is normally zero, but is not limited to this. The mounting head 5 is carried into the head maintenance device 7 by an operator, and maintenance is performed. Then, as indicated by an arrow R <b> 2 in FIG. 1, the head maintenance device 7 communicates and transmits maintenance information including the head identification code of the mounting head 5 that has performed maintenance and the maintenance result to the host system 2. The remaining number of operations calculator 11 sets the number of actual shots Mm corresponding to the head identification code to an initial value and stores it in the storage unit on the assumption that the maintenance result is “good” as an initial setting after performing maintenance. Let

The mounting head 5 is mounted on any of the component mounting machines 31 to 34 and performs an operation of mounting electronic components. Then, as indicated by an arrow R1 in FIG. 1, the remaining operation number calculation unit 11 acquires the actual shot number Mm of the mounting head 5 from the component mounting machines 31 to 34 together with the head identification code. In this case, the remaining operation number calculation unit 11 may directly acquire numerical information on the actual shot number Mm. Alternatively, the remaining operation number calculation unit 11 may acquire information indicating that the mounting head 5 has operated (for example, pulse signal information) every time, and perform a count-up process to obtain the actual shot number Mm. The remaining operation number calculation unit 11 stores the head identification code of each mounting head 5 and the remaining shot number Mr obtained by the calculation as a set. The actual shot number Mm and the remaining shot Mr do not change during the period in which the mounting head 5 is removed from the component mounters 31-34.

The operation frequency grasping unit 12 grasps the frequency at which the feeder device 4 installed in each of the slots of the four component mounters 31 to 34 operates, that is, the feeder feeding frequency n, corresponding to the type of board to be produced. Further, the operation frequency grasping unit 12 grasps the frequency at which the mounting heads 5 mounted on the four component mounters 31 to 34 operate, that is, the shot frequency m, corresponding to the type of board to be produced. The above-described production job data corresponds to the type of substrate and includes operation frequency information related to the operation frequency such as the feeder feed frequency n and shot frequency m. Therefore, the operation frequency grasping unit 12 is based on the production job data. The feed frequency n and shot frequency m can be easily grasped.

When the operator equips the slot of the component mounting machines 31 to 34 with the feeder device 4, the guide unit 13 mounts the component device equipped with each feeder device 4 based on the remaining feeder feed number Nr and the feeder feed frequency n. The machines 31 to 34 and their slot positions are guided. In addition, when the operator equips the component mounting machines 31 to 34 with the mounting head 5, the guide unit 13 uses the component mounting machines 31 equipped with the mounting heads 5 based on the number of remaining shots Mr and the shot frequency m. Guide ~ 34. The guide unit 13 is configured by arranging a monitor device 65 in the storage 8 and arranging a monitor device 61 in each of the component mounters 31 to 34. The guide unit 13 selects the feeder device 4 and the mounting head 5, and the guide information indicating the equipment position is for guiding the worker. The guidance information is displayed on both of the two monitor devices 61 and 65. Details of the guide information determination method and display method by the guide unit 13 will be described later together with the operation of the exchange support apparatus 1 and the work contents of the operator.

The operation time management unit 14 manages the cycle times Tc1 to Tc4 transmitted from the component mounters 31 to 34. As the actual number of shots Mm increases, the mounting head 5 tends to wear out and wear out, so that there is a slight delay tendency in the cycle times Tc1 to Tc4. For example, the drive speed tends to decrease due to insufficient lubricating oil in the drive mechanism or rough sliding surfaces. For this reason, the upper limit allowable operation time is set in advance as the management value of the cycle times Tc1 to Tc4 and is held in the operation time management unit 14.

The cycle times Tc1 to Tc4 are ideally the same for each component mounter 31 to 34, and production job data is also created with this as an optimization target. However, an imbalance occurs depending on the type of the board, and it is inevitable that the cycle times Tc1 to Tc4 are different between the component mounters 31 to 34. When any of the cycle times Tc1 to Tc4 timed by the component mounting machines 31 to 34 exceeds the allowable operation time, the operation time management unit 14 performs maintenance of the mounting head 5 of the component mounting machine for the number of remaining shots. Guide to implement regardless of Mr. This guidance information is displayed on the monitor device 61 of the component mounters 31-34.

The host system 2 includes identification information for identifying each component, such as a feeder identification code and a head identification code, for each component such as a plurality of feeder devices 4 and a plurality of mounting heads 5, and for each component. The storage unit stores the component information that associates the actual operation count information about the number of operations since the previous maintenance performed with the maintenance frequency information about the maintenance frequency for each component. The actual operation number information is based on information acquired by the remaining operation number calculation unit 11 from a work machine such as a component mounter. The maintenance frequency information includes, for example, information on the upper limit value of the number of operation of the recommended component from the previous maintenance to the next maintenance, information on the upper limit value of the elapsed time recommended from the previous maintenance to the next maintenance, etc. Information regarding the frequency of maintenance.

Next, the operation of the exchange support device 1 according to the embodiment and the work contents of the worker will be described. FIG. 2 is a sequence flow diagram for explaining the operation of the replacement support apparatus 1 of the component mounter and the work contents of the worker according to the embodiment. FIG. 2 illustrates a setup change operation when changing the type of substrate to be produced. Of the four columns arranged side by side in FIG. 2, the leftmost column indicates the work contents of the worker. The second column from the left shows the operation of the host system 2 as the exchange support apparatus 1. The third column from the left shows the operation as the guide unit 13 of the monitor device 61 of the component mounters 31 to 34. The rightmost column shows the operation of the monitoring device 65 of the storage 8 as the guide unit 13. Also, the passage of time is shown from the upper side to the lower side in FIG.

In the sequence S1 of FIG. 2, the operator changes the type of substrate to be produced. This change work is performed by the operator switching the old production job to the new production job from the input unit of the host system 2. As a result, in sequence S2, the host system 2 communicates and transmits new production job data, which replaces the old production job data, to each work machine on the board production line (see arrow R3 in FIG. 1). Then, in sequence S3, the monitoring devices 61 of the component mounters 31 to 34 provide guidance and display to the operator so as to perform a setup change operation for changing the type of board to be produced.

Next, in sequence S <b> 4, the exchange support device 1 makes a determination regarding the mounting head 5 equipped with the new production job data. As a specific first example, let us consider a case where each mounting head 5 mounted on the component mounting machines 31 to 34 based on the old production job data can be used as it is in the new production job data. In this case, the replacement support device 1 determines that it is not necessary to replace and mount the mounting head 5. As a second example, consider the case where the mounting head 5 is replaced and installed in the first and second component mounting machines 31 and 32 in accordance with the change from the old production job data to the new production job data. In this case, the remaining operation number calculation unit 11, the storage unit, and the guide unit 13 of the exchange support apparatus 1 operate in cooperation.

  In the second case, the replacement support apparatus 1 extracts candidates for the mounting head 5 that is newly equipped in the first and second component mounting machines 31 and 32. First, candidate extraction of the mounting head 5 equipped in the first component mounting machine 31 will be described. For example, the replacement support apparatus 1 is stored in the storage 8 at the time of extraction, and is the type designated by the new production job data, and the A mounting head 5A and the B mounting head 5B. , And C mounting head 5C. Next, the replacement support apparatus 1 acquires information on the operation frequency of the newly mounted mounting head 5 from the new production job data stored in the storage unit. For example, it is assumed that the value of the shot frequency as the operation frequency of the mounting head equipped in the first component mounting machine 31 is m1. Next, for each of the extracted A mounting head 5A, B mounting head 5B, and C mounting head 5C, the replacement support apparatus 1 stores the actual operation frequency information stored in the storage unit based on the head identification code, Get the specified number of operations information. Next, the remaining operation number calculation unit 11 of the replacement support apparatus 1 performs the next maintenance for each of the A mounting head 5A, the B mounting head 5B, and the C mounting head 5C based on the specified operation number information and the actual operation number information. The remaining number of operations, which is the remaining number of operations recommended up to now, is calculated. The remaining number of operations is calculated, for example, as the difference between the specified number of operations and the actual number of operations. For example, it is assumed that the number of remaining shots as the number of remaining operations of each mounting head extracted is MrA for the A mounting head 5A, MrB for the B mounting head 5B, and MrC for the C mounting head 5C. Next, the replacement support apparatus 1 determines whether or not each of the extracted mounting heads reaches the maintenance time before the production by the new production job data is completed. This determination may be made, for example, by determining whether the value of the number of remaining operations of each of the extracted mounting heads is greater than the value of the operation frequency at each equipment position in the new production job data. For example, when the replacement support apparatus 1 compares the value of the number of remaining operations of each mounting head with the value of the shot frequency in the first component mounting machine 31, it is MrA> m1, MrB> m1, and MrC <m1. Since the value of the remaining number of operations of the A mounting head 5A and the B mounting head 5B is larger than the value of the shot frequency at the first component mounting machine 31 in the new production job data, the replacement support apparatus 1 uses the A mounting heads 5A and B The mounting head 5B determines that the maintenance time is not reached before the production based on the new production job data is completed. Further, since the value of the number of remaining operations of the C mounting head 5C is smaller than the value of the shot frequency at the first component mounting machine 31 in the new production job data, the replacement support apparatus 1 uses the new production job It is determined that the maintenance period will be reached by the time data production is completed. Then, the replacement support device 1 updates the information indicating the A mounting head 5A and the B mounting head 5B, which are determined not to reach the maintenance time before the production based on the new production job data is completed, to the first component mounting machine 31. Is displayed on the guide unit 13 as a candidate for the mounting head 5 to be mounted on. For example, a head identification code may be displayed as information indicating a candidate for the mounting head 5. The candidate extraction of the mounting head 5 equipped in the second component mounting machine 32 is performed in the same manner. Here, the value of the shot frequency as the operation frequency of the mounting head mounted on the second component mounting machine 32 is m2, and the comparison between the value of the shot frequency and the value of the remaining number of operations of each mounting head is MrA> m2. Assume that MrB> m2 and MrC <m2. Accordingly, the replacement support apparatus 1 displays information indicating the A mounting head 5A and the B mounting head 5B on the guide unit 13 as candidates for the mounting head 5 newly equipped in the second component mounting machine 32.

Further, in the second example, a simple condition is considered in which the number of mounting heads 5 newly installed in the first and second component mounting machines 31 and 32 is limited to two, that is, the A mounting head 5A and the B mounting head 5B. . The A mounting head 5A and the B mounting head 5B are stored in the storage 8, and are the same type and compatible. For this reason, in the prior art, the first component mounting machine 31 may be equipped with the A mounting head 5A, and the second component mounting machine 32 may be equipped with the B mounting head 5B. The B mounting head 5B may be equipped, and the second component mounting machine 32 may be equipped with the A mounting head 5A.

On the other hand, in this embodiment, the guide unit 13 includes the remaining shot numbers MrA and MrB of the A mounting head 5A and the B mounting head 5B, and the shot frequencies m1 of the first component mounting machine 31 and the second component mounting machine 32, Based on m2, the component mounter equipped with the A mounting head 5A and the B mounting head 5B is specified and guided. Here, the remaining shot number MrA of the A mounting head 5A and the remaining shot number MrB of the B mounting head 5B are calculated by the remaining operation number calculation unit 11. As an example, the remaining shot number MrA of the A mounting head 5A is assumed to be smaller than the remaining shot number MrB of the B mounting head 5B. Further, the shot frequency m1 of the first component mounter 31 and the shot frequency m2 of the second component mounter 32 are grasped by the operation frequency grasping unit 12. As an example, it is assumed that the shot frequency m1 of the first component mounter 31 is smaller than the shot frequency m2 of the second component mounter 32.

The guide unit 13 equips the first component mounting machine 31 with a small shot frequency m1 with the A mounting head 5A having a small remaining shot number MrA, and the B mounting head 5B having a large remaining shot number MrB with a second component having a large shot frequency m2. It is determined that the mounting machine 32 is equipped. Further, in sequence S5, the guide unit 13 communicates and transmits to the monitor device 65 of the storage 8 the guide information for selecting a component among the guide information based on the determination result (see arrow R4 in FIG. 1). . Specifically, the guide unit 13 guides and displays the head identification codes of the A mounting head 5A and the B mounting head 5B as components to be equipped. At this time, it is not necessary to display the correspondence between the A mounting head 5A and the B mounting head 5B and the first component mounting machine 31 and the second component mounting machine 32.

Next, in sequence S <b> 6, the exchange support device 1 makes a determination regarding the feeder device 4 equipped with the new production job data. First, the replacement support apparatus 1 lists a new electronic part type required for new production job data, a required number of feeder apparatuses 4 holding reels of the part type, and a slot position to be equipped. Next, the exchange support apparatus 1 searches for the feeder apparatus 4 that is stored in the storage 8 and that holds the reel of the component type. This search is easily performed on the basis of the correspondence between the grasped device code and the feeder identification code. If the necessary number of feeder devices 4 holding reels of the relevant component type are sufficient, the search is terminated. If there is a shortage, the replacement support device 1 searches the feeder device 4 stored in the storage 8 and capable of holding the reels of the component type until the necessary number is reached. In this case, for the insufficient number of feeder devices 4, an operator's work is required to set the reels of the corresponding component type in the reel holder.

Next, consider the third case as an example of when the search is completed and candidates for the feeder device 4 to be equipped with the new production job data are listed. FIG. 3 shows the component mounting machine replacement support device 1 according to the embodiment. FIG. 11 is an explanatory diagram of a third case illustrating the function of the guide unit 13. In the third case, the equipment of four feeder devices 4 is required to supply an electronic component of a certain component type by new production job data. In addition, the four feeder devices 4 are installed at the slot S1 of the first component supply device 31, the slot S2 of the second component supply device 32, the slot S3 of the third component supply device 33, and the fourth component supply device 34. Slot S4.

As shown in FIG. 3, the number P of parts supplied in each of the slots S1 to S4 defined in the new production job data is P1 = 100, P2 = 150, P3 = 800, and P4 = 300. Therefore, the operation frequency grasping unit 12 can grasp the feeder feeding frequency proportional to the component supply numbers P1 to P4 of the slots S1 to S4. For example, the feeder feed frequency is maximized in the slot S3 of the third component supply device 33 that is the maximum value with the component supply number P3 = 800, and the slot S1 of the first product supply device 31 that is the minimum value with the component supply number P1 = 100. The feeder feed frequency is minimized. In the third case, the guide unit 13 uses the component supply numbers P1 to P4 that can be handled in the same manner instead of the feeder feeding frequency.

  Next, candidates for the feeder device 4 equipped in each of the slots S1 to S4 are extracted. First, candidate extraction of the feeder device 4 installed in the slot S1 will be described. For example, the exchange support apparatus 1 has five feeder apparatuses 4A to 4E on the condition that it is stored in the storage 8 at the time of extraction and is the type designated by the new production job data. Extract. Next, the exchange support apparatus 1 acquires information on the operation frequency of the newly installed feeder apparatus 4 from the new production job data stored in the storage unit. The value of the component supply number P1 handled as the operation frequency of the feeder device 4 installed in the slot S1 is 100. Next, the exchange support apparatus 1 acquires the actual operation number information and the prescribed operation number information stored in the storage unit for each of the extracted feeder devices 4A to 4E based on their feeder identification codes. Next, the remaining operation number calculation unit 11 of the replacement support device 1 recommends the remaining operation recommended for the next maintenance for each of the feeder devices 4A to 4E based on the specified operation number information and the actual operation number information. The remaining number of operations Nr, which is the number of operations, is calculated. For example, the specified number of operation times Nk of each of the extracted feeder devices 4A to 4E is 100,000. Assume that the actual feeder feed numbers Nm, which are the actual operation counts of the feeder devices 4A to 4E, are NmA = 500, NmB = 100, NmC = 80000, NmD = 50000, and NmE = 99950, respectively. Therefore, the remaining operation number calculation unit 11 calculates the remaining operation number of each of the feeder devices 4A to 4E as NrA = 99500, NrB = 99900, NrC = 20000, NrD = 50000, and NrE = 50. Next, the exchange support device 1 determines whether or not each of the extracted feeder devices 4A to 4E reaches the maintenance time before the production by the new production job data is completed. Since the value of the remaining number of operations NrA to NrD of the feeder devices 4A to 4D is larger than the value of the number of parts supplied P1 = 100 in the slot S1 in the new production job data, the replacement support device 1 has the feeder devices 4A to 4D It is determined that the maintenance time is not reached before the production by the new production job data is completed. Further, since the value of the number of remaining operations of the feeder device 4E is smaller than the value of the number of parts supplied P1 = 100 in the slot S1 in the new production job data, the replacement support device 1 uses the new production job data for the feeder device 4E. It is determined that the maintenance time will be reached before production is completed. Then, the replacement support device 1 is newly equipped with information indicating the feeder devices 4A to 4D, for example, feeder identification codes, which are determined not to reach the maintenance time before the production by the new production job data is completed, in the slot S1. As a candidate for the feeder device 4A. The candidate extraction of the feeder device 4A installed in the slots S2 to S4 is performed in the same manner.

Four feeder apparatuses 4A to 4D are listed as candidates for the feeder apparatus 4 installed in each of the slots S1 to S4. For this reason, in the prior art, which feeder device 4A-4D may be equipped in which slot S1-S4.

In contrast, in the present embodiment, the guide unit 13 is based on the remaining feeder feed numbers NrA to NrD of the four feeder apparatuses 4A to 4D and the component supply numbers P1 to P4 of the four slots S1 to S4. The slots S1 to S4 equipped with the feeder devices 4A to 4D are specified and guided. Here, the same feeder feed number Nk = 100000 for the four feeder apparatuses 4A to 4D is the same. Further, the actual feeder feeding numbers Nm of the four feeder apparatuses 4A to 4D are respectively obtained as NmA = 500, NmB = 100, NmC = 80000, and NmD = 50000. Therefore, the remaining feeder feed numbers Nr calculated by the remaining operation number calculation unit 11 are NrA = 99500, NrB = 99900, NrC = 20000, and NrD = 50000, respectively.

The guide unit 13 determines that a feeder device 4 having a larger remaining feeder feed number Nr is installed in a slot having a larger component supply number P, and a feeder device 4 having a smaller remaining feeder feed number Nr is installed in a slot having a smaller component supply number P. . In the example of FIG. 3, as indicated by the white arrow, the guide unit 13 equips the slot 4 of the third component mounting machine with the feeder device 4 </ b> B, and places the feeder device 4 </ b> C in the slot S <b> 1 of the first component mounting machine 31. Judge to equip. Further, the guide unit 13 determines that the feeder device 4A is installed in the slot S4 of the fourth component mounter and the feeder device 4D is installed in the slot S2 of the second component mounter 32.

Further, in the sequence S7 of FIG. 2, the guide unit 13 displays the guide information for selecting a component among the guide information based on the determination result on the monitor device 65 of the storage 8 (see arrow R4 in FIG. 1). Specifically, the guide unit 13 guides and displays feeder identification codes of the four feeder apparatuses 4A to 4D as components to be equipped. At this time, it is not necessary to display the correspondence between the four feeder apparatuses 4A to 4D and the four slots S1 to S4.

Next, in sequence S <b> 8, the worker moves to the storage and confirms the guide information displayed on the monitor device 65. The operator can take out the two mounting heads 5A and 5B of the second case and the four feeder apparatuses 4A to 4D of the third case without error by following the guidance information (FIG. 1). (See arrows R5 and R6). Next, in sequence S <b> 9, the operator updates and inputs take-out information indicating that the two mounting heads 5 </ b> A, 5 </ b> B and four feeder devices have been taken out from the input unit of the monitor device 65.

Thereby, in sequence S10, the host system 2 updates the current state of the two mounting heads 5A, 5B and the four feeder devices from “in storage in the storage 8” to “in extraction”. Next, in sequence S11, the host system 2 displays guidance information related to the component installation positions on the monitor devices 61 of the four component mounting apparatuses 31 to 34 (see arrow R3 in FIG. 1). Specifically, the monitor device 61 displays the head identification code of the A mounting head 5A in association with the first component mounting machine 31 and the head identification code of the B mounting head 5B in association with the second component mounting machine 32 for guidance display. . Further, the monitor device 61 guides and displays the four sets of correspondence shown in FIG. 3, for example, the correspondence between the slot S1 of the first component mounter 31 and the feeder identification code of the feeder device 4C.

Next, in sequence S12, the operator transports the two mounting heads 5A and 5B and the four feeder devices toward the component mounting machines 31 to 34, and confirms the guide information displayed on the monitor device 61. . By following the guidance information, the operator can install the two mounting heads 5A, 5B and the four feeder devices without error in the guided mounting positions of the component mounting machines 31-34 (see FIG. 1 arrow R7). Next, in sequence S13, each control unit of the component mounting machines 31 to 34 recognizes that the two mounting heads 5A and 5B and the four feeder devices 4A to 4D are installed. Information indicating that it is equipped is communicated and transmitted to the host system 2 and shared.

In sequence S14, the host system 2 confirms that the two mounting heads 5A and 5B and the four feeder apparatuses 4A to 4D are mounted at the guided mounting position. Then, the host system 2 updates the current state of the two mounting heads 5A and 5B and the four feeder apparatuses from “being taken out” to “equipped”. Thereafter, the production of the substrate based on the new production job data is started.

In the setup change operation, the number of components (feeder device 4 or mounting head 5) that can be installed may be larger than the number of locations at the installation position. In this case, the guide unit 13 provides guidance so as to preferentially equip components having a large remaining feeder feed number Nr and a remaining shot number Mr.

Further, during the production of the board, the feeder device 4 or the mounting head 5 may reach the maintenance time in any of the four component mounting machines 31 to 34. Even in this case, when there are a plurality of candidates for the replacement element (feeder device 4 or mounting head 5), the guide unit 13 is appropriate based on the remaining feeder feed number Nr, the remaining shot number Mr, and the operation frequency at the equipment position. Exchange elements can be selected. For example, the guide unit 13 selects and guides an exchange element having a performance operation number close to the actual feeder feed number Nm of another feeder device 4 that is already installed or the actual shot number Mm of another mounting head 5. Further, for example, the guide unit 13 selects and guides a candidate having the largest remaining feeder feed number Nr and the remaining shot number Mr from among a plurality of candidates for exchange elements.

As described above, when it is repeated to select and equip components, a plurality of components can be leveled and used. As a result, the number of performance operations of the plurality of components approximate each other, and the arrival of the maintenance time approaches. Also, the degree of wear and exhaustion of the plurality of components is similar. Therefore, the performance is the same in the four component mounters 31 to 34 equipped with these plural components. If a good mounting head 5 immediately after maintenance is installed in the first component mounting machine 31 and a worn mounting head 5 that is about to be maintained next time is installed in the second component mounting machine 32, two cycles are installed. There is a large difference between times Tc1 and Tc2. In this case, the production efficiency of the entire component mounting line 3 is reduced by the delay of the cycle time Tc2 of the second component mounter 32.

  An exchange support device 1 according to the embodiment is a component (feeder device) that is installed and operated in a replaceable manner at an installation position of a work machine (component mounting machines 31 to 34) arranged in a board production line for mounting electronic components on a board. 4. Support the replacement of the mounting head 5). The exchange support apparatus 1 stores production job data that stores production job data corresponding to the type of board to be produced, including operation frequency information (shot frequency, number of parts supplied) regarding the operation frequency of the components mounted at the equipment position. Section (storage unit), identification information (head identification code, feeder identification code) for identifying each component, and the number of operations performed since the last maintenance performed on the component, for each of the plurality of components Component element information storage for storing component element information in which operation frequency information (number of actual shots, number of actual feeder feeds) and maintenance frequency information (regular shot number, predetermined number of feeder feeders) regarding the frequency of maintenance for the elements are associated with each other Component (storage unit), production job data, and component information. The determination unit that determines whether or not the maintenance time is reached before the production based on the production job data is completed, and the component that the determination unit determines that the maintenance time is not reached before the production based on the job data is completed And an output unit (guide unit 13) for outputting information indicating.

According to this, the guide unit 13 outputs information indicating a component that is determined not to reach the maintenance time until the production by the production job data is completed. Therefore, the operator can reduce the occurrence of components that reach the maintenance time during production by installing the components at the equipment position according to the output that takes the maintenance time into account.

The component mounting machine replacement support device 1 according to the embodiment includes components (feeder device 4) that are installed in a plurality of mounting positions of four component mounting machines 31 to 34 that mount electronic components on a substrate in a replaceable manner. For the mounting head 5), the maintenance time for performing maintenance is individually managed, and the arrival of the maintenance time is guided. For the plurality of components, the exchange support apparatus 1 sets the upper limit value of the number of operations recommended during the maintenance interval period as the specified number of operations Nk and Mk, and sets the number of operations performed since the previous maintenance as the actual number of operations Nm and Mm. The remaining operation number calculation unit 11 for calculating the remaining operation number Nr and Mr based on the specified operation number Nk and Mk and the actual operation number Nm and Mm, and the configuration at a plurality of equipment positions corresponding to the type of board An operation frequency grasping unit 12 for grasping each of the element operation frequencies n and m (or the number P of parts supplied), and a part of the components provided at the equipment position due to the change of the type of the board or the maintenance time When the worker equips the constituent element due to the fact that it has reached the number of operations, the configuration is required based on the remaining number of operations Nr, Mr and the operation frequency n, m (or component supply number P). A guide portion 13 for guiding the equipped position, with a.

According to this, the guide unit 13 considers the remaining number of operations Nr, Mr recommended until the next maintenance of the component and the operation frequency n, m (or the number P of parts supplied) at the equipment position. Guidance of equipment position. Therefore, the worker can equip the equipment position with the component according to the guidance considering the maintenance time, and the maintenance of the component is made efficient. In addition, the efficiency of maintenance contributes to the improvement of production efficiency.

Furthermore, in the exchange support device 1 of the embodiment, when the operator equips two or more components, the guide unit 13 selects the components having the remaining number of operations Nr and Mr as the operation frequencies n and m (or component supply). The monitor device 61 guides the mounting of the component having a large number of remaining operations Nr and Mr to the device position having a large operation frequency n and m (or component supply number P). In addition, the remaining operation number calculation unit 11 calculates the remaining operation numbers Nr and Mr by subtracting the actual operation numbers Nm and Mm from the specified operation numbers Nk and Mk.

According to this, the remaining number of operations Nr and Mr gradually approach with two or more components. For example, in FIG. 3, the feeder device 4C in which the remaining feeder feed number NrC is only 20000 is installed at the equipment position where the component supply number P1 is the minimum value, and the decrease in the remaining feeder feed number NrC is suppressed. On the other hand, the feeder apparatus 4B in which the remaining feeder feed number NrB is 99900 is installed in the equipment position where the component supply number P3 is the maximum value, and the reduction of the remaining feeder feed number NrB is promoted. If the selection of components and the determination of equipment positions are continued in this way, the remaining feeder feed numbers NrA to NrD of a large number of feeder devices 4 come closer to each other. Then, the maintenance of the plurality of feeder devices 4 approaches the same period. The same applies to the plurality of mounting heads 5.

Here, as is well known, the remaining operation times Nr and Mr are not strict, so that maintenance may be performed even if some remaining operation times Nr and Mr remain. Thereby, maintenance of a some component can be collectively implemented in the same period. In other words, the maintenance time can be concentrated, maintenance can be made more efficient, and the labor of the operator can be reduced. Also, the degree of wear and exhaustion of the plurality of components is similar. As a result, the performance of the four component mounters 31 to 34 equipped with a plurality of components is uniform, and the deviation between the cycle times Tc1 to Tc4 decreases. Therefore, it is possible to contribute to the improvement of production efficiency by the central effect of the maintenance time and the comprehensive effect of the deviation reduction of the cycle times Tc1 to Tc4.

Furthermore, in the replacement support device 1 of the embodiment, the guide unit 13 arranges the monitor device 65 in the storage 8 that stores a plurality of components (feeder device 4 and mounting head 5), and the monitoring device 61 in the component mounting machine. Is arranged.

According to this, the operator can confirm the guidance information regarding the selection of the component to be equipped and the equipment position at a familiar position. Therefore, the work efficiency is improved, and the possibility that the components are mistaken or the equipment position is wrong is reduced.

Furthermore, the exchange support device 1 of the embodiment has a feeder identification code assigned to the feeder device 4 and a head identification code assigned to the mounting head 5, and the maintenance time is individually managed using these identification codes.

According to this, the exchange support apparatus 1 can be realized using a computer apparatus such as the host system 2. Therefore, labor for individually managing the maintenance time is saved, and management reliability is high.

Furthermore, in the replacement support apparatus 1 of the embodiment, the remaining operation number calculation unit 11 includes the feeder identification code and the actual feeder feed number Nm of the feeder device 4 installed in the component mounting machines 31 to 34 and the head identification of the mounting head 5. The code and the actual shot number Mm are received from the component mounters 31-34.

According to this, the remaining feeder feed number Nr and the remaining shot number Mr can be automatically managed. Therefore, the labor of management is greatly saved, and the reliability of management is improved.

Further, in the replacement support device 1 of the embodiment, the remaining operation number calculation unit 11 receives a head identification code of the mounting head 5 that has performed maintenance from the head maintenance device 7 that is responsible for maintenance of the mounting head 5, and The actual operation count Mm is set to an initial value (usually zero).

According to this, the initial setting of the actual operation number Mm is automatically performed after the maintenance of the mounting head 5 is performed. Therefore, the labor of management is further greatly saved, and the initial setting is performed reliably.

Furthermore, the exchange support apparatus 1 according to the embodiment further includes an operation time management unit 14. When the cycle time Tc1 to Tc4 required for the operation of the component mounting machines 31 to 34 exceeds a preset allowable operation time, the operation time management unit 14 performs maintenance of the mounting head 5 equipped in the component mounting machine. Guidance is made regardless of the number of remaining shots Mr.

According to this, when the performance of the mounting head 5 deteriorates earlier than the maintenance time, the performance can be recovered by performing the maintenance regardless of the number of remaining shots Mr. Therefore, a decrease in production efficiency can be suppressed.

In the embodiment, the maintenance is performed in units of the mounting head 5, but the maintenance may be performed in units of mounting nozzles. Further, regarding the selection of components and the determination of the equipment position, it is also conceivable to use another method different from the embodiment. For example, another method is possible in which maintenance of a plurality of components can be performed collectively when lot production is completed and a setup change operation to the next lot having a different substrate type is performed. In this alternative method, the guide unit 13 selects a component to be equipped in consideration of the planned production number and actual production number of substrates, and determines the equipment position.

Furthermore, although the operation time management unit 14 manages the cycle times Tc1 to Tc4 required to mount the specified number of electronic components on one board by each of the component mounting machines 31 to 34, another method is also conceivable. . For example, the time required for the mounting head 5 to pick up an electronic component with the feeder device 4, move to the substrate, mount the electronic component 2, and return to the feeder device 4 is called a mounting cycle time. The operation time management unit 14 may guide maintenance of the mounting head 5 based on the delay tendency of the mounting cycle time.

In addition, the feeder device 4 and the mounting head 5 that are the management targets of the exchange support device 1 of the embodiment may be mounted interchangeably on a component mounting machine of another board production line. In this case, the host system 2 acquires the actual feeder feed number Nm of the feeder device 4 and the actual shot number Mm of the mounting head 5 from a plurality of substrate production lines.

  The replacement support apparatus 1 according to the embodiment supports the replacement of the feeder apparatus 4 and the mounting head 5 that are mounted in the mounting positions of the component mounting machines 31 to 34 and operate. The replacement support apparatus 1 may support replacement of components that are mounted and operated in a replaceable manner at an installation position of a solder printing machine arranged on the board production line. As a component equipped in a solder printer, for example, there is a squeegee for pushing solder placed on a mask superimposed on a substrate as a printing object into an opening provided in the mask. .
