Abstract

PROBLEM TO BE SOLVED: To provide a component replenishment method in which, when replenished with a wrong electronic component, the electronic component can be detected surely, in which a component feed means with exhausted components is removed from the object of a component mounting operation, and in which the productivity of an electronic-component mounting apparatus can be enhanced. SOLUTION: The discrimination number of a component feed means 9 in which components are exhausted during production is registered in a storage means 33, and a memory 17 in the component feed means 9 is initialized. Its initialization is canceled automatically at a point of time when components are replenished so as to register information on the electronic components in the memory 17. The initialization of the component feed means 9 with exhausted components is not canceled as long as it is not replenished with components. When the registration of the discrimination number into the storage means 33 is held, the component feed is always checked when it is replenished with components. When the initialization of the memory 17 is canceled, the contents of the memory 17 are read out, and the components are collated.

A rotary type mounting head unit 7 is provided above which is provided with a plurality of suction nozzles 4 for picking up electronic components and mounting them on the circuit board 2. Thus, the suction nozzles 4 are sequentially positioned at the mounting positions.

[0005] A required electronic component is sequentially supplied from a component supply table 8 to a component supply position in the apparatus main body 1 where the electronic component is sucked by the suction nozzle 4. The component supply table 8 has a large number (for example, 75) of component supply units 9 described later shown in FIG. 4 mounted in parallel, and is moved in the parallel direction of the component supply units 9. Further, the component supply tables 8 are arranged on both left and right sides of the apparatus main body 1 (only the right side is shown in FIG. 3), and are provided on a path between the component supply position of the apparatus main body 1 and the table standby position 10 on the side. The replacement of the component supply means 9 is performed in a state where the component supply table 8 is retracted to the table standby position 10 when switching the production type of the circuit board 2 or running out of components. This table standby position 10
When the replenishment operation of the electronic parts to the parts supply means 9 is completed in the
Is operated, whereby the controller 5 of the apparatus main body is notified of the completion of the component replenishment, and is put into an operable state.

Further, the component supply table 8 sequentially positions each component supply means 9 at a predetermined component supply position in accordance with the order of electronic components to be mounted while moving in the parallel arrangement direction of the component supply means 9. . This component supply means 9
The electronic component is sucked and taken out by the suction nozzle 4 of the mounting head unit 7, and is transferred and mounted on the positioned circuit board 2 by rotation of the mounting head unit 7. The control of each operation described above is performed by a control device 5 provided in the device main body 1.

[0005] In the component supply table 8, each component supply means 9 is mounted at a location individually designated by an identification number. As shown in FIG. 4, the component supply means 9 which is generally called a parts cassette includes a cover tape (not shown) in which the same kind of electronic components are accommodated in a carrier tape (not shown) at equal intervals by taping means.
Is wound around a reel 11 in a state covered with a feed lever 12 by a driving mechanism (not shown) of the apparatus main body 1.
Every time is pushed in, the carrier tape is fed out from the reel 11 and sent at a pitch equal to the storage interval of the components, and the cover tape is taken up by the take-up reel 13 so as to be sent to the frontmost component supply port 14. The mounted electronic component is positioned at a component supply position facing the suction nozzle 4 of the mounting head unit 7. The component supply means 9 includes a non-contact magnetically readable and writable memory 17. The memory 17 includes names and remaining numbers of electronic components to be stored on the reel 11 set in the reel holding unit 18. Are registered and stored.

In FIG. 3, a read / write head 19 is mounted at a position above the movement path of the component supply table 8 in the apparatus main body 1. When moving along the movement path, the component supply means 9 mounted on the movement path
When the data passes below, data is read from and written to the memory 17 with respect to the name of the component and the remaining number. Various data are input by operating the keyboard of the input device 20, and the status of the device and the contents of the data are displayed on the display screen of the display unit 21.

FIG. 5 is a perspective view showing the external appearance of an external device for reading and writing the contents of the memory 17 of the component supply means 9. In the drawing, the component supply means 9 removed at the table standby position 10 for component replenishment is replaced with a new reel 11 to perform component replenishment. Temporarily attached. At this time, the memory 17 of the component supply means 9 faces the read / write head 24 of the external device in a readable / writable state. The external device includes a terminal device 27, and the terminal device 27 includes:
An input unit 28 for inputting new data by an operation of a worker, a bar code reader 29 provided in the component supply means 9 for reading a bar code on which the names of electronic components and the remaining number are displayed, and a read / write unit. The data read by the write head 24 from the memory 17 or the data newly input by operating the input unit 28 or the bar code reader 2
There is provided a display unit 30 for displaying data and the like read by 9.

FIG. 6 is an explanatory diagram of an array program P which is data defining the mounting positions of a large number of component supply means 9 in the component supply table 8. The identification number data D1 is data in which the identification number indicating the number of the mounting position of the component supply means 9 in the component supply table 8 and the number unique to each component supply means 9 is stored. Part name data D
Reference numeral 2 denotes data that stores a character string that uniquely defines the name of an electronic component. The master designation data D3 indicates that the part supply means 9 for mounting electronic parts as spare parts
This is data that stores the identification number of the component supply means 9 on which the master component of the electronic component is mounted.

For example, an array program P shown in FIG.
, The identification number in the parts supply table 8 is “3”
The component supply means 9 on which the same electronic component indicated by “C” is mounted is attached to each of the mounting positions of “” to “5”. Here, the electronic component "C" of the component supply means 9 having the identification number "3" is treated as a master component, and "4",
Each of the electronic components “C” of the component supply unit 9 with the identification number “5” is a spare part for the electronic component of the component supply unit 9 with the identification number “3”. Therefore, when the electronic component of the component supply unit 9 with the identification number of “3” is out of components, the electronic component of the component supply unit 9 with the identification number of “4” or “5” is used as a substitute. Production of the circuit board 2 is continued.

Next, a conventional component replenishment method will be described with reference to a flowchart of FIG. The control device 5 in the device main body 1 constantly monitors whether or not the component supply means 9 has run out of components during production (step S).
1) If a component has run out, it is determined whether or not there is a spare part for the electronic component whose part has run out (step S2). If a spare part exists, the spare part is used. Continue production of the circuit board 2 (step S
3) If it is determined that the spare parts have also run out of parts (step S2), it is determined whether there is any other electronic part that is of a type to be mounted on the circuit board 2 under production and has not run out of parts. It is determined (step S4), and if there is, the production of the circuit board 2 is continued until the electronic component is exhausted (step S5). As described above, even if a component is cut out, if there are electronic components that can be mounted on the circuit board 2 under production, the component supply table can be obtained by mounting all the electronic components and then replenishing the components. 8 is frequently moved to the table standby position 10 and interruption of operation due to component replenishment is prevented as much as possible, thereby preventing a decrease in productivity.

When the mounting of the electronic components that have not been exhausted is completed and it is determined that all of the electronic components mountable on the circuit board 2 under production have been exhausted (step S4). The component supply table 8 is moved to the table standby position 10 by a command from the control device 5 (step S6). When the component supply table 8 passes just below the read / write head 19 in the process of moving to the table standby position 10, the read / write head 19 counts the number of mounted electronic components, thereby providing the component supply means 9. The remaining number of electronic components calculated for each is rewritten in the memory 17 of the corresponding component supply means 9.

The control device 5 causes the display unit 21 to display the identification number of the component supply means 9 that has run out of components. The operator operates the display unit 21 of the component supply means 9 mounted on the component supply table 8 stopped at the table standby position 10.
Supply unit 9 at the mounting position of the identification number displayed in
That is, components are replenished by taking out only the component supply means 9 which has run out of components and replacing the reel 11 of the component supply means 9 with a new one (step S).
7).

Next, the operator registers the names and remaining numbers of the electronic components mounted on the newly set reel 11 in the memory 17 of the component supply means 9 (step S).
8). At the time of this registration, the component supply means 9 whose reel 11 has been replaced is attached to the means mounting base 23 of the external device,
Means for directly inputting data by manual operation of the input unit 28 via the read / write head 24 or the reel 11
A barcode reader 2
9 by means of reading.

Subsequently, the worker presses the component replacement completion switch 22 after mounting each of the component supply means 9 whose reels 11 have been replaced at the mounting positions of the predetermined identification numbers of the component supply table 8 respectively. Then, the control device 5 is notified that the electronic component replenishment work has been completed (step S
9). Thus, the electronic component mounting apparatus is ready to resume operation, and moves the component supply table 8 from the table standby position 10 to the component supply position of the apparatus body 1. When the component supply table 8 passes just below the read / write head 19, the control device 5 sets only the component supply means 9 that have been determined to be out of components before replenishment of the component to the position directly below the read / write head 19. While the positioning is sequentially stopped, the name and the remaining number of the electronic components mounted on the component supply means 9 are read from the memory 17 by the read / write head 19 (step S10).

The controller 5 compares the name of the electronic component read from the memory 17 with the component name registered in advance in the array program P of FIG. S11). That is, it is determined whether or not the identification number of each mounting position in the component supply table 8 matches the type of the electronic component mounted on the component supply means 9 mounted at these mounting positions. If all of the component supply means 9 that have been subjected to component verification match, it is determined that electronic components have been refilled correctly, the component supply table 8 is moved to the component supply position, and production by mounting electronic components is resumed ( Step S12). If there is at least one component supply unit 9 having a component name mismatch, it is considered that a different electronic component is erroneously mounted, and the component supply table 8 is moved to the table standby position 10 again (step S6). A message instructing re-supply of the electronic component is displayed on the display unit 21.

[0016]

By the way, at the time of replenishment of electronic parts, it is not always necessary to replenish the electronic part as a master part which has run out of parts as long as a spare part for the part is replenished. However, when the operator operates the component replacement completion switch 22, the control device 5 regards all of the component supply means 9 registered as out of components before the component replenishment as replenishing electronic components. And specify it as a target for parts collation. However, in this case, the component verification (step S11) is only a comparison as to whether the identification number and the component name match, and the remaining number is not checked. Therefore, the component supply means 9 that has not been replenished returns the table to the table standby position 10 because the identification number and the component name match in the component collation, and the collation result is the same as when the component is replenished correctly. It is sent to the component mounting position without being performed.
Then, the component supply unit 9 becomes a target for mounting the electronic component, and when the suction failure by the suction nozzle 4 continues for a predetermined number of times, it is determined that the component is out of use. This is one factor that causes a decrease in productivity.

The reason why the component names are collated after the components are replenished is that the controller 5 determines that all the electronic components that can be mounted on the circuit board 2 under production have run out and replenishes the components. Only when instructed. For example, in the case of a setup change due to a change in the type of the circuit board 2 to be produced, a worker moves the component supply table 8 to the table standby position 10 at his / her own discretion and replenishes necessary electronic components. In such a case, the component name is not collated when the component supply table 8 returns to the component mounting position.

For this reason, for example, the component supply means 9 having the identification numbers "4" and "5" shown in the arrangement program P of FIG.
However, at the time of component replenishment based on a command from the control device 5, the component replenishment of the component supply means 9 having the identification number of "3" designated as the master component is not performed, and the component replenishment is not performed. "4" that parts are not replenished,
When reels 11 of electronic components different from those specified in the array program P are erroneously mounted on the component supply means with the identification number of “5” at the time of setup change or the like, these “4”, “5” Is considered to have already been performed at the time of component replenishment based on a command from the control device 5, and is not subjected to component collation at the end of setup change or the like. . In such a case, an incorrect electronic component is mounted on the circuit board 2, which causes a problem that a defective circuit board 2 is produced.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object of the present invention is to ensure that when an erroneous electronic component is replenished in the electronic component supply means, this is ensured. It is an object of the present invention to provide a component replenishment method for an electronic component mounting apparatus that can detect and remove a component supply unit that has run out of components from components to be mounted, thereby improving productivity.

[0020]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a component supply apparatus in which a plurality of component supply means on which required electronic components are mounted are mounted at mounting positions of individually assigned identification numbers. In the component replenishment method of the electronic component mounting apparatus for retreating the table from the component mounting position to the table standby position and replenishing the component supply means that has run out of components with a predetermined electronic component, the electronic component is mounted on the circuit board during A recognition number registration step of registering the identification number of the component supply unit in which the component has run out in the storage unit, and all the electronic components of a type that can be mounted on the circuit board being produced are out of component and the component supply table is deleted. In the process of moving to the table standby position, a memory initialization step of initializing a memory provided only for the component supply means for which a recognition number has been registered; After a predetermined electronic component is replenished to the component supply means removed from the component supply table at the table standby position, information on the replenished electronic component is updated and registered in the memory, thereby eliminating initialization. In the process of moving the component supply table to the component mounting position after completion of component replenishment, the component supply table includes a component collation step of checking each of the memories only for the component supply unit whose identification number has been registered, In the part collation step, if the initialization of the memory has not been resolved, the registration of the identification number is retained, and if the initialization of the memory has been resolved, the electronic memory stored in the memory is retained. The information on the parts is checked against the registered information, and if the information is correct, the registration of the identification number is deleted and the parts supply data is deleted. And so as to allow the movement of the component mounting position Le.

In this component replenishment method, the identification number of the component supply means in which a component shortage has occurred during production is registered in the storage means, and the memory of the component supply means registered as the component shortage is initialized prior to the component replenishment. Since the initialization is canceled when the information of the electronic component is registered in the memory after the component is replenished, the component supply unit that has run out of the component can not cancel the initialization unless the component is replenished, and in the component out state. There is a registration held. With this, the component supply unit that has not been replenished can be excluded from the target of component mounting because the registration of the component exhaustion is held, and the suction nozzle can be removed from the empty component supply unit. Waste of repeating the suction operation a predetermined number of times can be eliminated, and productivity can be improved accordingly. In addition, since the part supply means that has run out of parts is not deleted unless the parts are replenished, it is always subject to a check at the time of parts replenishment, and when initialization is resolved, the contents of the memory are read out and parts collation is performed. Therefore, when an incorrect electronic component is replenished, it can be reliably detected. Therefore, it is possible to reliably prevent the inconvenience that the wrong electronic component is mounted on the circuit board.

Further, in the above-mentioned parts collating step, if the initialization of the memory of the parts supply means has not been eliminated, the spare parts in which the same electronic parts as those to be mounted on the parts supply means are replenished. The presence / absence of the component supply means for the spare is searched, and when the component supply means for the spare exists, the component supply table of the component supply table is retained while the registration of the identification number of the component supply means for which initialization has not been completed is maintained. It is preferable to adopt a method of permitting movement to a component mounting position and instructing to move the component supply table to a table standby position when there is no spare component supply unit.

Thus, even when the replenishment of components to all the component supply means is not completed, the replenishment of the electronic components of all types is completed, and the production is started when the mounting on the circuit board can be performed without any trouble. Is resumed, and the registration of the identification number is retained for the component supply means that have not been replenished, so that the component supply means can be excluded from the target of component mounting,
Productivity can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. The configuration of the electronic component mounting apparatus to which the component replenishment method of the present invention is applied is as described with reference to FIGS. 3 to 6, and FIG. 1 is for embodying the component replenishment method according to one embodiment of the present invention. 3 is a functional block diagram showing the configuration of the first embodiment. 3, the component shortage detection unit 31 includes a suction impossible detection sensor 32 that detects that the suction nozzle 4 in FIG. 3 has not suctioned an electronic component.
When the suction nozzle 4 detects through the suction failure detection sensor 32 that the electronic component has not been able to continuously suck the electronic component a predetermined number of times, it is determined that the component supply means 9 is out of components. The component replenishment incomplete list holding unit 33 temporarily stores and holds the identification number of the component supply unit 9 of the component exhaustion notified from the component exhaustion detection unit 31.

The memory controller 34 controls the movement of the component supply table 8 in FIG. 3 via the supply table controller 37 so that the memory 17 of the required component supply means 9 is positioned just below the read / write head 19. The component supply table 8 is intermittently stopped so as to face the state, and the contents of the memory 17 of the component supply means 9 are read / written via the read / write head 19 in FIG. Here, when the component supply table 8 moves toward the table standby position 10, the memory control unit 34 controls the component replenishment incomplete list holding unit 33.
, The part replenishment incomplete list holding unit 3
Initialization is performed on the memory 17 of the component supply means 9 corresponding to the identification number stored and held in the memory 3.

Specifically, initialization mark data is written into the memory 17.

The array program holding unit 38 stores and holds an array program P which is a list of the identification number data D1, the component name data D2, and the master designation data D3 shown in FIG. When the component replacement is completed and the component replacement completion switch 22 is operated, the component collating unit 39 stores in the memory 17 of the component supply unit 9 that the component supply unit 9 has read out through the read / write head 19 by the memory control unit 34. It is checked whether or not the component name of the component coincides with the component name held in the array program holding unit 38. Only when the component name matches, the movement to the component mounting position of the component supply table 8 is permitted to start the production. Let it resume. On the other hand, if they do not match, the component supply table 8 is moved again to the table standby position 10 by a U-turn, and a message of a component replenishment error is displayed on the display screen of the display unit 21.

FIG. 2 is a flowchart showing the processing of the component replenishment method according to one embodiment of the present invention. The component shortage detecting unit 31 constantly monitors whether or not a component shortage has occurred in the component supply means 9 through the suction impossible detection sensor 32 (step S21). If a component shortage occurs, the component shortage occurs. The identification number of the attached position of the component supply means 9 is registered in the component replenishment incomplete list holding unit 33 (step S22). The control device 5 refers to the contents of the array program P registered in the array program holding unit 38 and the contents of the component replenishment incomplete list holding unit 33, and there is a spare part of the electronic component whose component has been exhausted. It is determined whether or not there is a spare part (step S23). If there is a spare part, the production of the circuit board 2 is continued using the spare part (step S24).

If it is determined that the spare part is also out of parts (step S23), the circuit board 2 under production is
It is determined whether or not there is another electronic component that is of a type that can be mounted on the device and has not been exhausted (step S2).
5) If it exists, mounting of each electronic component that can be mounted is continued while skipping mounting of the component supply unit 9 whose identification number has been registered in the component replenishment incomplete lift holding unit 33 (step S26). Thereby, the component supply table 8
Is frequently moved to the table standby position 10 to prevent interruption of operation due to component replacement as much as possible, thereby preventing a decrease in productivity.

If it is determined that all the electronic components of the type that can be mounted on the circuit board 2 under production have run out (step S25), the component supply table 8 is moved to the table standby position 10. An instruction is given (step S27). When the component supply table 8 passes directly below the read / write head 19 in the process of moving to the table standby position 10, the memory control unit 34 recognizes each identification number registered in the component replenishment incomplete list holding unit 33. The initialization is performed via the read / write head 19 on the memory 17 of the component supply means 9 mounted on each of the components (step S28).

Then, when the parts supply table 8 is moved to the table standby position 10 and is in a state of waiting for parts replenishment work, the worker is registering in the parts replenishment incomplete list holding part 33 displayed on the display part 21. The component supply means 9 mounted on the component supply table 8 while checking the identification number of
Out of the component supply means 9 at the mounting position of the identification number displayed on the display section 21 of the
The reel 11 is replaced with a new reel to replenish components (step S29). Subsequently, the worker registers the name and the remaining number of the electronic component mounted on the newly set reel 11 in the memory 17 of the component supply means 9 using the external device shown in FIG. 4 (step S30). ), The initialization is automatically canceled by performing this registration. Specifically, the mark data indicating the initialization is deleted.

Subsequently, the worker presses the component replacement completion switch 22 after attaching each of the component supply means 9 whose components have been replenished by replacing the reel 11 to the mounting position of the corresponding identification number in the component supply table 8. To notify that the electronic component replenishment work has been completed (step S
31). Thereby, the electronic component mounting apparatus returns to the state where the operation can be resumed, and moves the component supply table 8 from the table standby position 10 to the component supply position of the apparatus main body 1 (step S32). When the component supply table 8 passes just below the read / write head 19, the memory control unit 34 reads / writes only the component supply unit 9 corresponding to the identification number registered in the component replenishment incomplete list holding unit 33. The contents of each memory 17 are read by the write head 19 (step S33), and it is determined from the read contents whether or not the memory 17 has been initialized (step S34).

When the memory control unit 34 determines that the component name and the remaining number are correctly registered in the memory 17 and the initialization has been canceled (step S34), the memory control unit 34 then proceeds to step S34. The name and the component name registered in advance in the array program P of FIG. 7 are compared to check whether they match (step S35). That is, it is determined whether or not the identification number of each mounting position in the component supply table 8 matches the type of the electronic component mounted on the component supply means 9 mounted at these mounting positions. If they match, it is determined that the replenishment of the electronic component has been correctly performed, and the identification number of the component supply means 9 is deleted from the component replenishment incomplete list holding unit 38 (step S36).

Thereafter, it is determined whether or not the component collation in step S35 has been completed for all of the identification numbers registered in the component replenishment incomplete list holding unit 38 (step S37). In this case, the process returns to step S33 to repeat the component collation based on the content read from the memory 17. When it is determined that all the component verifications have been completed (step S37), the component supply table 8 is moved to the component supply position, and production by mounting electronic components is resumed (step S38).

On the other hand, when it is determined that the memory 17 is still initialized (step S34), the component supply means 9 for mounting the same electronic component as the spare component as the spare component corresponding to the identification number is used. It is determined whether or not the component is present. If the component is present, it is checked whether or not the component supply means 9 is replenished with components (step S3).
9). If there is spare part supply means 9 and the parts supply means 9 has been replenished, the identification number corresponding to the parts supply means 9 whose memory 17 has been initialized without parts being replenished. Then, the process jumps to step S37, while being registered in the component replenishment incomplete list holding unit 33. As a result, the component supply means 9 that has run out of components
Even if the parts have not been replenished, if the electronic parts as substitutes for the electronic parts have been replenished to the other parts supply means 9, the production is resumed as it is.

On the other hand, if it is determined in step S39 that there is no spare part or that spare parts have not been replenished, the parts supply table 8 is moved to the table standby position 10 again (step S2).
7) A message for instructing replacement of the electronic component is displayed on the display unit 21. Also, when it is determined in step S35 that the component names do not match, it is considered that another electronic component is erroneously mounted, and the component supply table 8 is moved to the table standby position 10 again (step S27).

In this component replenishment method, even if there is a component supply unit 9 in which the memory 17 remains initialized without the component replenishment, a spare part of the electronic component to be mounted on the component supply unit 9 is replaced with another spare part. Parts have been replenished to the parts supply means 9,
If the electronic component can be used as a substitute, the production is restarted with the identification number corresponding to the component supply means 9 that has not been replenished remaining in the component replenishment incomplete list holding unit 33. As a result, it is possible to prevent a decrease in productivity due to waiting for the resumption of production until the replenishment of components to all the component supply means 9 is completed.

Also, the memory 17 of the component supply means 9 that has not been replenished has been initialized, and the identification number corresponding to the component supply means 9 has been registered in the component replenishment incomplete list holding unit 33. Since the component supply means 9 is excluded from the components to be mounted and is skipped during component mounting, it is possible to prevent the suction nozzle 4 from performing a component suction operation on the empty component supply means 9.

Further, when replenishment of components is performed by the judgment of the operator, such as when the type of the circuit board 2 to be produced changes and the type of the circuit board 2 is changed, the replenishment is not registered in the component replenishment list holding unit 33. All of the component supply means 9 are subjected to component collation. These component supply means 9 do not cancel the initialization of their own memory 17 unless a correct component name and the remaining number are registered in the memory 17 by the external device of FIG. The identification number corresponding to itself remains registered in the component replenishment incomplete list holding unit 33. Therefore, when the control unit of the apparatus main body 1 replenishes parts based on a judgment of an operator other than when instructing the replenishment of parts, the electronic part of the wrong kind is replenished to the part supply means 9 for spare parts. Can reliably detect this and prevent the mounting of the wrong electronic component.

In the above embodiment, an electronic component mounting apparatus having a structure including the rotary mounting head 7 and the board positioning table 3 movable in the X and Y orthogonal directions has been described as an example. The component replenishment method can, of course, be applied to an electronic component mounting apparatus configured to mount electronic components by an orthogonal robot having a mounting head for suction or mounting.

[0041]

As described above, according to the component replenishment method of the electronic component mounting apparatus of the present invention, the identification number of the component supply means that has run out of parts during production is registered in the storage means, and prior to the component replenishment. The memory of the component supply means that has been registered as having run out of parts has been initialized, and the parts have been replenished and the initialization has been canceled when the information of the electronic component has been registered in the memory. Since the initialization is not canceled unless it is performed, and the registration that the component is out of stock is kept, so that the component supply means that has not been replenished has registered that the component is out of stock. It can be excluded from the target of component mounting,
The productivity can be improved by preventing useless suction operation by the suction nozzle. In addition, a part supply unit that has run out of parts retains its registration as long as parts are not replenished, is always checked for replenishment of parts, and performs part collation based on the contents of the memory when initialization is resolved. Therefore, it is possible to reliably detect when an incorrect electronic component is replenished, and it is possible to reliably prevent a problem such as mounting an incorrect electronic component on a circuit board.

Claims (2)

[Claims] A component supply table in which a plurality of component supply means on which required electronic components are mounted is mounted at a mounting position of an identification number assigned to each of them is retracted from a component mounting position to a table standby position. In a component replenishment method of an electronic component mounting apparatus for replenishing a predetermined electronic component to the out-of-stock component supply means, a recognition number of the component supply means in which the electronic component has run out of components during mounting on a circuit board is stored. In the step of registering the identification number to be registered in the means, and in the step of moving all the electronic parts of the kind that can be mounted on the circuit board under production and moving the parts supply table to the table standby position, the identification number is registered. A memory initializing step of initializing a memory provided in only the component supply means, and reading from the component supply table at the table standby position. After replenishing a predetermined electronic component to the removed component supply means, an initialization resolving step of resolving the initialization by updating and registering information on the replenished electronic component in the memory; and In the process of moving the component supply table to the component mounting position, the device includes a component collation step of checking each memory only for the component supply means for which the identification number has been registered, and in the component collation step, If the initialization has not been resolved, the registration of the identification number is held, and if the initialization of the memory has been resolved, the information on the electronic component stored in the memory is regarded as the regular registration information. Verification is performed, and only when the information is correct, the registration of the identification number is deleted, and the movement of the component supply table to the component mounting position is permitted. Parts replenishment method of the electronic component mounting apparatus according to claim. 2. In the part collating step, if the initialization of the memory of the part supply means has not been canceled, a spare part in which the same electronic parts as those to be mounted on the part supply means have been replenished. The presence / absence of the supply means is searched, and when the spare part supply means is present, the component mounting position of the part supply table is retained while the registration of the identification number of the part supply means which has not been initialized is retained. 2.
