The splicing registration information is registered which includes normal information in which the splicing process has been correctly performed or failure information in which the splicing has failed. Before starting manufacturing of a next generation product, based on the splicing registration information, a next generation product feeder which requires splicing again is discriminated.

Description

  The present invention relates to an electronic component mounting method and an electronic component mounting apparatus in which a plurality of feeders for supplying electronic components stored in a storage tape are provided on a mounting base, and electronic components are taken out from a predetermined feeder and mounted on a printed circuit board. About.

  This type of electronic component mounting method and apparatus are disclosed in, for example, Patent Document 1, but as shown in FIG. 4, for each feeder, feeder information (a unique serial number of the feeder) and component information (electronic component It is registered (stored) in the server in association with the component ID, which is the name.

  On the other hand, by performing the mounting operation of the electronic component, the electronic component is removed from the feeder by the suction nozzle, so that the remaining number of electronic components is reduced. Splicing is performed by connecting and supplying a new storage tape to be connected to the current storage tape being supplied by a connecting member.

  The prior art shown in Patent Document 1 discloses a solution to failure in splicing for the current production model.

JP 2010-141215 A

  Further, it is necessary to perform the above-mentioned splicing even in a feeder that is not used in the current production model. At that time, a storage tape storing electronic components different from the electronic components stored in the current storage tape is connected and spliced. In many cases, splicing is performed again with the correct storage tape, but sometimes the user forgets to perform the splicing operation with the correct storage tape and has not re-spliced. In rare cases, the storage tape may be mistaken for splicing and the next storage tape may be spliced.

  However, in the prior art, there is no recognition of the problem with splicing in the next production model as described above. Therefore, in the prior art, regardless of whether or not the splicing is normally performed during the production of the current production model, all the splicing is processed normally when the next production model is produced. .

  Therefore, there is a possibility that the storage tape containing the wrong electronic component is still spliced or the splicing itself has not been performed. When switching to a production model that uses this feeder, the current part, which is the storage tape that was supplying the electronic parts to the current production model, is checked for parts crossover and used / unmatched parts are judged. However, the spliced new storage tape electronic components are not checked because the splicing information is not maintained. Therefore, if wrong parts remain connected, different types of electronic components for the feeder will be mounted on the printed circuit board, resulting in a problem of producing a defective board. .

  Therefore, according to the present invention, when splicing is performed on a feeder that is not used in the current production model, it is possible to connect storage tapes that store wrong different electronic components, or to leave the wrong storage tape connected. An object of the present invention is to provide an electronic component mounting method or an electronic component mounting apparatus that prevents production of defective substrates.

Furthermore, the present invention is characterized in that the splicing registration information includes failure information indicating that the splicing processing has not been performed normally as initial information.

In addition, the present invention is characterized in that the splicing registration registers failure information indicating that the splicing registration has not been performed normally in the splicing registration information when the splicing process has not been performed normally. To do.
Furthermore, the present invention has a fifth feature that, as a result of the confirmation step, when all the splicing registration information is not normal, the next model production step is not performed.

Further, according to the present invention, when the splicing registration matches the part ID attached to the storage tape connected to the next model feeder and the part ID to be connected to the next model feeder, the splicing registration information It is a sixth feature that the normal information is registered in.
Further, the present invention has as a seventh feature that the splicing registration is performed after the splicing process.

  In addition, the present invention obtains a part ID that should be included in the storage tape set in each lane necessary for production of the next production model, and the part ID and the current part set in the lane. The eighth feature is that a cross check is performed to check whether the part ID of the storage tape attached to the model feeder or the next model feeder matches.

Has a lane number in the 400s.

  Each of the feeder carts 3A, 3B, 3C, and 3D includes a plurality of feeders 5 arranged side by side on a feeder base (mounting table) of a cart table (not shown) that is a mounting table. Is detachably disposed on the apparatus main body 2 via a connector (not shown) so as to face the conveyance path of the printed circuit board P (hereinafter simply referred to as a substrate), and the handle is released by releasing the connector. And can be moved by a caster provided on the lower surface.

  The feeder carts 3 </ b> A, 3 </ b> B, 3 </ b> C, and 3 </ b> D are each provided with the feeder 5 such that the tip on the component supply side faces the pickup area of the mounting head 6. Each feeder 5 includes a tape feeding mechanism that intermittently feeds the storage tape C, which has been sequentially wound in a state of being wound around a supply reel that is rotatably mounted on the cart table, to a suction and extraction position of an electronic component by a feed motor 17; And a cover tape peeling mechanism for peeling the cover tape Ca from the carrier tape just before the suction take-out position by driving the peeling motor 18, and peeling the cover tape Ca by the cover tape peeling mechanism and loading it into the carrier tape storage section The electronic components thus obtained can be sequentially supplied to the suction extraction position and taken out from the tip portion by a suction nozzle described later.

  In addition, feeder information (feeder serial number, a unique number of each feeder 5) is described on a predetermined portion of each feeder 5, for example, a handle used when attaching to or removing from the cart table. The label is attached. In addition, the supply reel on which the storage tape C is wound and stored has a label on which component information (part ID which is the name of the electronic component and the storage quantity of the electronic component) is formed. .

  Between the feeder carts 3B and 3D on the front side and the feeder carts 3A and 3C on the back side, there are two supply conveyors, positioning units 8 and 8 (having a conveyor), and a discharge conveyor constituting the substrate transport mechanism. Is provided. Each supply conveyor transports each printed circuit board P received from upstream to each positioning unit 8, and after each electronic component is mounted on each substrate P positioned by a positioning mechanism (not shown) in each positioning unit 8, It is transported to each discharge conveyor and then transported to the downstream device.

  Each beam 10 that moves along the guide rail 9 by the X-axis drive motor 11 in the Y direction is provided with a mounting head 6 that is moved by the X-axis drive motor 13 in the longitudinal direction, that is, in the X direction. Are provided with a plurality of suction nozzles. The mounting head 6 is equipped with a vertical axis drive motor 14 for moving the suction nozzle 6 up and down, and a θ-axis drive motor 15 for rotating around the vertical axis. Therefore, the suction nozzle 13 of the mounting head 6 can move in the X direction and the Y direction, can rotate about the vertical axis, and can move up and down.

  Reference numeral 12 denotes a component recognition camera that captures an image of the electronic component in order to recognize the position of the electronic component in the XY direction and the rotation angle to determine how much the electronic component is displaced and held with respect to the suction nozzle. Each electronic component is picked up by the component recognition camera 12 while being sucked and held by the suction nozzle 13 and is recognized by the recognition processing device 23 described later.

  Next, the control block diagram of FIG. 2 will be described. The electronic component mounting apparatus 1 includes a CPU (Central Processing Unit) 20 as a control apparatus that performs overall control of the mounting apparatus 1, and a bus line connected to the CPU 20. RAM (Random Access Memory) 21 and ROM (Read Only Memory) 22 are provided. The CPU 20 controls the operation related to the component mounting operation of the electronic component mounting apparatus 1 according to the program stored in the ROM 22 based on the data stored in the RAM 21. That is, the CPU 20 controls the drive of the Y-axis drive motor 11, the X-axis drive motor 13, the vertical axis drive motor 14, the θ-axis drive motor 15, and the like via the interface 24 and the drive circuit 27, and The feed motor 17 and the peeling motor 18 are controlled via the drive circuit 16.

  The RAM 21 stores mounting data for each type of printed circuit board P related to component mounting. For each mounting order (step number), the X direction (indicated by X) in the printed circuit board P, Y Information of direction (indicated by Y) and angle (indicated by Z), arrangement number information of each feeder 5, and the like are stored.

  The RAM 21 stores information on the type (component ID) of each electronic component corresponding to the feeder arrangement number of each feeder 5 for each type of printed circuit board P, that is, component arrangement information (see FIG. 3). This component arrangement information is data relating to which position of the feeder 5 is mounted on the cart table. For example, an electronic component with a component ID “COMP-ID-01” is stored in the lane number “101”. This means that the feeder 5 that handles the supply reel around which the storage tape C to be wound is wound is mounted. Further, component library data relating to the characteristics of the electronic component is stored for each component ID.

  A recognition processing device 23 is connected to the CPU 20 via the interface 24. The recognition processing device 23 performs recognition processing of an image captured by the component recognition camera 12, and the processing result is sent to the CPU 20. Is sent out. That is, the CPU 20 outputs an instruction to the recognition processing device 23 so as to perform recognition processing (calculation of misalignment amount) on the image captured by the component recognition camera 12 and receives the recognition processing result from the recognition processing device 23. It is.

  Reference numeral 25 denotes a monitor for displaying a part image and a screen for setting various data. The monitor 25 is provided with various touch panel switches 26 as input means. Can be set.

  28 is an input means, 30A and 30B are barcode scanners as reading devices, the barcode scanner 30A is provided as a part of the electronic component mounting apparatus 1, and the barcode scanner 30B is connected to the electronic component mounting apparatus 1. Yes. Both the barcode scanners 30A and 30B are each provided with feeder information (serial number, unique number of each feeder 5) composed of a barcode written on a label attached to a predetermined portion of the feeder 5, and a storage tape. The component information (component ID which is the name of the electronic component and the storage quantity of the electronic component) is read from the barcode written on the label attached to the supply reel in which C is wound and stored. The component information is not limited to the supply reel, and may be information described on, for example, a label attached to the top of the storage tape C.

  Reference numeral 31 denotes a personal computer (hereinafter referred to as a “personal computer”) provided with a microcomputer connected to the electronic component mounting apparatus 1 via the LAN line 32, which is also stored via the LAN line 32. It is connected to a server 33 as means. A monitor 34 as a display device and an input means 35 such as a keyboard are connected to the personal computer 31.

  The server 33 is connected to the personal computer 31 via the LAN line 32. The server 33 is connected to the feeder information (feeder serial number and component ID (electronic component name) correspondence table (see FIG. 4)). ) Is stored.

  Here, when the electronic component mounting apparatus 1 is automatically operated, the printed board P is conveyed from the upstream apparatus to the positioning unit 8 via the supply conveyor, and is positioned and fixed by the positioning mechanism.

  Next, the mounting head 6 moves according to the mounting data stored in the RAM 21, and the electronic component to be mounted by the suction nozzle 13 corresponding to the component type of the electronic component is sucked out from the predetermined feeder 3.

  Specifically, the suction nozzle of the mounting head 6 moves so as to be positioned above the feeder 5 that stores the electronic components to be mounted in accordance with the mounting order, but in the Y direction, the Y-axis drive motor 11 is driven to move the beam 10. In the X direction, the X-axis drive motor 13 is driven to move the mounting head 6, and the predetermined feeder 5 is already driven so that the component can be taken out at the component suction position. The suction nozzle is lowered to suck and take out the electronic component, and then the mounting head 6 is lifted.

  The suction nozzle moves so as to mount the electronic component at a predetermined position on the printed circuit board P positioned by the positioning unit 8. While the mounting head 6 moves, the component recognition is performed while the mounting head 6 moves. The electronic component sucked and held by the suction nozzle 13 when passing the upper position of the camera 12 is imaged by the component recognition camera 12 (fly recognition).

  Then, based on this imaging result, how much the electronic component is displaced and held with respect to the suction nozzle is recognized by the recognition processing device 23 with respect to the XY direction and the rotation angle, and the recognition processing result of the electronic component The CPU 20 controls the Y-axis drive motor 11, the X-axis drive motor 13, and the θ-axis drive motor 15 to be mounted at predetermined positions on the printed circuit board P. Similarly, other electronic components are similarly corrected and mounted.

  Here, the splicing will be described. First, by performing the mounting operation of the electronic component, the electronic component is supplied and removed from the feeder 5 by the suction nozzle, so that the remaining number of the electronic component is reduced. For this reason, since the feeder 5 is fixed on the cart table and does not move, the feeder 5 is connected to the old storage tape C that is currently supplying the electronic component and the new storage tape C to be connected during the automatic mounting operation. Splicing (see FIGS. 5 and 6) to be connected and replenished with a tape is performed.

  Specifically, the supply reel of the storage tape C of the feeder 5 in which the remaining number of electronic parts is reduced is removed from the feeder base of the cart base, and the storage tape C wound around the supply reel is further removed. Near the end of the old storage tape C wound around the supply reel, the carrier tape and the cover tape Ca are located at the same surface position and in the middle of the adjacent feed holes Cb and in the storage portion Cc. Cut with a cutter at the center in the feed direction.

  Next, separately from this, at the starting end of a new storage tape C wound around the supply reel, the carrier tape is positioned in the middle of the adjacent feed holes Cb and the central position in the feed direction of the storage portion Cc. And cut with a cutter so that the cover tape Ca is longer than the carrier tape. Then, the new storage tape C and the old storage tape C are aligned with the cut end surfaces so that the semicircular feed holes Cb form a circular feed hole Cb. Are superposed so as to cover the cover tape Ca of the new storage tape C, and the old storage tape C and the new storage tape C are connected by the connecting tapes 108A, 108B and 108C.

Next, based on the flowchart shown in FIG. 7, the operation | movement which concerns on the splicing for the next production model is demonstrated to the case of the feeder cart 3A as an example.
The feeder 5 that is not used in the current production model 1 but is planned to be used in the next production model 2 is already installed on the feeder base in preparation for the next production model. It has been. FIG. 4 shows the current part information (part ID which is the name of the electronic part and the quantity of electronic parts stored) of the feeder 5 attached to the feeder cart 3A. The current part information of the feeder is acquired by the apparatus from the server 33 and stored (registered) in the RAM 21 together with the production model to be used corresponding to the feeder information of the feeder (feeder serial number which is a unique number of the feeder). . The numbers in the column of production models represent production models, 1 represents the current production model 1, and 2 represents the next production model 2.

  Therefore, when the splicing process for producing the next production model 2 is selected, FIG. 4 is displayed on the monitor 34 (S1). The operator determines a feeder 5 that needs to be spliced for the next production model 2 with reference to FIG. For example, in the range shown in FIG. 4, a feeder whose feeder serial numbers are FDR-ID-001 and FDR-ID-005 is a feeder used for the next production model 2. FDR-ID-001 determines that splicing is necessary because the quantity of remaining electronic components is small, while FDR-ID-005 indicates that splicing is unnecessary because the quantity of remaining electronic components is large. Judgment is made (S2). If it is determined that splicing is necessary, “1” is registered in the column corresponding to FDR-ID-001 in the splicing registration information shown in FIG. 9 (S3). “1” indicates a failure in which splicing is necessary or not performed normally, and “0” indicates that splicing has been completed normally or is unnecessary. Therefore, “0” indicating that it is unnecessary is already entered in the column corresponding to FDR-ID-002 to FDR-ID-004 used in the current production model 1. That is, as an initial value of the splicing registration information, “0” indicating unnecessary in this embodiment is entered. FIG. 9 is displayed together with FIG.

  Unlike the above embodiment, whether or not splicing is necessary may be automatically determined based on a predetermined standard. In that case, the steps S2 and S3 are unnecessary, and automatically determined splicing registration information is registered in the columns corresponding to FDR-ID-001 and FDR-ID-005.

Next, splicing is performed on the feeder serial number FDR-ID-001 (S4).
FIG. 8 is a flowchart showing the splicing process. First, it is determined whether a splicing process during production of the current production model 1 or a splicing process during feeder setup in the next production model 2 described later (SS1). If it is the splicing process during the production of the current production model 1, go to SS2. If it is the splicing process during the feeder setup in the next production model 2, since the splicing is already performed or the splicing process is not performed and the storage tape is in the state of the current production model, the process goes to SS8.

  In SS2, the feeder serial number written in the barcode attached to the feeder 5 is read by the barcode scanner. Then, the component ID of the current storage tape C that is already attached corresponding to the feeder serial number is acquired from the server 33. FIG. 4 shows an example of the component ID acquired from the server (SS3).

  Next, the component information (component ID which is the name of the electronic component and the storage quantity of the electronic component) is read from the barcode attached to the supply reel on which the new storage tape C to be coupled is wound and stored, and the component ID is obtained ( SS4). It is determined whether the part ID of the current storage tape C matches the part ID of the new storage tape C (SS5). If they match, the current storage tape C and the new storage tape C are spliced and connected ( SS6). Here, it is not determined that splicing has been performed normally. This determination is made in the final confirmation step described below. If they do not match, the new storage tape C is replaced with the next candidate (SS7), and the process returns to SS4.

  After the connection, for confirmation, the component ID is read again from the barcode on the label attached to the supply reel on which the new storage tape C is wound and stored (SS8). It is determined again whether the current storage tape C, the new storage tape C, and the component ID match (SS9). If they match, it is determined that the splicing process has been performed reliably, so instead of the information “1” indicating the failure in which splicing is necessary or not performed normally in the splicing registration information column shown in FIG. Information “0” indicating that splicing has been normally performed is registered (SS10).

  If they do not match, splicing has failed and the splicing registration information shown in FIG. 9 is maintained at “1”. Of course, 1 ″ may be input again (SS11). FIG. 10 shows the relationship between the component ID of the current storage tape C and the component ID of the new storage tape C when splicing fails. Feeder serial number of the feeder 5 The electronic component necessary for FDR-ID-001 indicates that the component ID spliced against COMP-ID-001 is COMP-ID-009.

  10 indicates that the part ID of the current storage tape C described as (registered) in the column of the table in FIG. 10 is stored as data, and the part ID of a new storage tape without (registration) is stored as data. Not remembered. Of course, the part ID of the new storage tape C may also be stored as data.

  If the splicing fails, for example, the monitor 34 displays a device abnormality message “The connected component does not match the current component” and notifies the operator (SS12). However, since the splicing registration failure in the feeder 5 not used in the current production model is not related to the current production, the apparatus is not stopped even when the apparatus is in production operation. Then, if the operator is spliced and connected while continuing the operation of the apparatus, the operator removes the connecting tapes 108A, 108B and 108C (SS13), and again performs the splicing process from SS4.

  In the splicing registration information column in the case where they do not match, information “1” indicating that splicing has not been normally performed, that is, that further splicing processing is necessary, is maintained as failure information. If they do not match, “1” may be consciously registered in the splicing registration information column.

  Returning to S2 in FIG. 7, it is determined whether or not there is a feeder 5 that requires further splicing with reference to FIG. 4, and if there is a necessary feeder 5, processing is repeated from S3. If there is no necessary feeder 5, it waits for the production of the current production model 1 to end (S5).

In the embodiment described above, it is determined whether the part IDs of the current storage tape C and the new storage tape C are the same before and after splicing, but it may be either before or after splicing. However, since it is determined that the current storage tape C and the new storage tape C are finally connected when the determination is made after splicing, the splicing registration information can be reliably registered.
In the embodiment described above, if the splicing registration information is automatically generated based on the determination of whether or not both the component IDs of SS9 match, the possibility of forgetting the registration is reduced.

  The flow described above shows a state where processing is normally performed. However, sometimes, for example, the feeder 5 that is interrupted during the process of FIG. 8 and requires the next splicing if the splicing process is performed without splicing or if the wrong splicing is not repeated. May go to the process. When splicing is not performed normally, “1” indicating that splicing is necessary is maintained as splicing failure information.

According to the embodiment described above, since the data to be spliced is first registered in the splicing registration information or registered in advance, when the splicing is not performed again or the splicing process is not performed, This splicing failure information is transmitted as check information before starting production of the next production model.
In addition, even if it is determined that splicing is unnecessary even if the quantity stored in S2 in FIG. 7 is small, it is necessary to install the wrong electronic component only by eliminating the electronic component early in the production of the next production model 2. There is no production of defective products.

  In the embodiment described above, since the data to be spliced is first registered or registered in advance in the splicing registration information, even if splicing is not performed despite splicing necessary, the splicing registration information includes Always remain as data to be spliced. Therefore, before the production model 2 is produced, the necessity of splicing can be determined again based on the splicing registration information, and the splicing can always be performed correctly.

  Next, a feeder setup process flow related to the feeder when the operation of the current production model 1 is completed and the model is switched to the operation of the next production model 2 will be described with reference to FIG. FIG. 12 is a table summarizing feeder serial numbers (feeder information) and component IDs (component information) and component ID check results for each lane number (feeder arrangement number) necessary for the operation of the next production model 2. Both pieces of information are acquired from the server 33 inside the apparatus when the model is switched.

  In FIG. 12, the splicing registration information column indicates the result of splicing registration performed during the operation of the production model 1. In the cross registration information column, the result of the cross check to be performed is registered (stored). The cross registration information is set to “NG” as an initial value. FIG. 12 shows the time-series change of the cross check result, but the state at that time is actually registered. The cross check is performed until all the lanes finally become OK. However, the cross check may sometimes not be completed.

  First, a component ID (component information) necessary for feeder setup is acquired from the server 33 and displayed on the monitor 34 together with splicing registration information in the form shown in FIG. 12 (S10). Next, for each lane, the component ID shown in FIG. 12 acquired from the server 33 is compared with the component ID held in the RAM 21 inside the apparatus at the end of production of the production model 1 shown in FIG. A crossover check is made to see if they match (S11). The determined result is shown as the second of the time-series data in the cross registration information column. If the comparison collation matches and it is determined that the crossing is “no”, the data in the crossing registration information column for the lane is rewritten from “NG” to “OK” (S12). On the other hand, if the comparison and collation do not match and it is determined that the difference is “present”, the data in the difference registration information column for the lane is maintained at “NG”. In this embodiment, the lane numbers 103 and 105 are different from each other in the range shown in FIG.

  In S11, the lanes spliced during production of the production model 1 need not be compared. In FIG. 4, when the quantity stored at the end of the production model 1 is small, “NG” is maintained regardless of the result of the comparison and collation, or splicing is necessary, and the splicing registration information field shown in FIG. Is changed to “1”.

  Next, the presence / absence of the cross feeder 5 is determined (S13). If there is a cross feeder 5, a cross check is performed on the lane where the cross is over, and a new feeder 5 is set in the lane (S14). If there is no cross feeder 5, the process proceeds to S15 depending on the necessity of splicing.

  FIG. 13 is a flowchart showing a new feeder set process (S14). First, the operator removes the currently installed feeder 5 (SS21). Pick up the feeder 5 that seems to be applicable, read the feeder serial number from the bar code written on the label attached to the feeder 5, check if it is the feeder 5 to be set in the corresponding lane, and set it ( SS22). After that, the component information (component ID which is the name of the electronic component and the storage amount of the electronic component) from the barcode written on the supply reel on which the storage tape C set in the feeder 5 is wound and stored. Is read (SS23).

Next, it is determined whether or not the read component ID of the feeder 5 matches the component ID acquired from the server 33 shown in FIG. 12 (SS24). If the two match, “OK” is registered in the component ID check field of FIG. 12 (SS25), and the process returns to the main routine. On the other hand, if they do not match, the process returns to SS22 and the next candidate feeder 5 is processed again.
The new candidates in the above are often prepared in advance in the corresponding lanes. Therefore, in the processing flow of FIG.

When the process of the cross feeder 5 is completed, the splicing process is performed again if necessary based on the splicing registration information shown in FIG. 12 held in the apparatus.
First, it is determined whether there is a lane having splicing failure information “1” in the splicing registration information (S15). If there is splicing failure information “1”, the process goes to the splicing processing subroutine shown in FIG. 8, and the splicing processing is executed again (S16). In the splicing process during feeder setup in the next production model 2, since the feeder 5 is already set on the feeder base, the subroutine in FIG. The process from SS8 is the same as the process during production of the production model 1.

  In the embodiment described above, if the current production model 1 is spliced to the next production model 2 performed during production, there will be no problem if the splicing process is normally performed for all feeders 5 that require many splicing. There is no. However, for example, when it becomes necessary to perform other operations in the middle of this series of processing, the continuity of the processing is lost, sometimes splicing is performed, or the wrong storage tape C is spliced. It may be maintained.

  However, according to the embodiment described above, whether splicing is necessary or not based on the splicing registration information again before production of the production model 2 even if splicing is not performed or not performed even though splicing is necessary. By determining, splicing can be performed correctly.

  Also, according to the embodiment described above, on the contrary, in the rare case, even if the splicing necessity is input to the splicing registration information shown in FIG. Prior to production, unnecessary splicing processing can be avoided by determining the necessity of splicing again based on the splicing registration information.

  Therefore, according to the embodiment described above, the splicing process can be performed correctly, and the production model 2 can be produced without mounting wrong electronic components on the board.

Finally, just in case, after setting up the feeder shown in FIG. 11, when the production operation start switch of the production model 2 is pressed, the part ID check result shown in FIG. It is checked whether there is “NG” indicating the presence of “1” or “1” indicating splicing failure in the splicing column.
If there is “NG” indicating the presence of the cross feeder, an activation guidance message indicating that the feeder cannot be started is displayed on the monitor 34 to notify the operator, and control is performed so that the production operation cannot be started. The startup guidance message is, for example, “Parts are misplaced in the feeder. The device cannot start production operation”.
Similarly, if there is “1” indicating failure of splicing, an activation guidance message indicating that the splicing cannot be started is displayed on the monitor 34 to notify the operator, and control is performed so that the production operation cannot be started. The start guidance message is, for example, “the parts connected by the feeder do not match the current parts. The device cannot start production operation”.

  As a result, when the production operation start switch of the production model 2 is pressed, the production model is checked by checking for “NG” indicating the presence of the cross feeder and “1” indicating the splicing failure in the splicing column. By not performing step 2, it is possible to prevent the production of a defective substrate without mounting a wrong type of electronic component.
