Description

  The present invention relates to a component replenishment system for an electronic component mounting apparatus that efficiently implements a replenishment operation of electronic components without reducing productivity.

2. Description of the Related Art Conventionally, there is a board unit production line for creating a board unit in which a large number of chip-like electronic components (hereinafter simply referred to as components) are mounted on a printed circuit board (hereinafter simply referred to as a substrate). This substrate unit production line includes, for example, a substrate supply device that supplies a substrate, a dispenser that attaches or applies paste solder or the like to a predetermined position on the supplied substrate, and a substrate to which the solder or the like is attached or applied. Electronic component mounting device for mounting components (hereinafter simply referred to as component mounting device), a reflow furnace for fixing the mounted components on the substrate, and a substrate storage device for storing the completed board unit with the mounted components fixed Etc. (For example, refer to Patent Document 1.)
In the board unit production line as described above, for example, the component mounting apparatus can be said to occupy the most important position. There are various types of component mounting apparatuses, but there is a one-by-one type component mounting apparatus that is compact and has a small design turn. This one-by-one component mounting apparatus is movable up and down (Z direction) to a work head that moves freely in the front and rear (Y direction) and left and right (X direction) in the work space above the board carried into the apparatus. A mounting head that is rotatable in 360 degrees (θ direction) is provided, and a component is mounted on the substrate by this mounting head.

The mounting head has a suction nozzle that is detachably attached to the tip of the mounting head. The suction nozzle sucks the component from the component supply device, and the sucked component is already accurately positioned and stopped at a predetermined position. Mount on the board. (For example, see Patent Document 2.)
By the way, there are various types of component supply devices for supplying components to the above component mounting device, but the most commonly used type is a tape-type component supply device. The tape-type component supply device attaches a component tape containing components between two types of bonded tape members to a replaceable tape holding reel, and feeds this component tape to a supply port. Supply individual parts. Depending on the size of the component mounting apparatus, 100 to 140 such tape-type component supply apparatuses can be attached to a single component mounting apparatus. (For example, refer to Patent Document 3.)
When the board unit production model is switched, it is necessary to replace the tape-type component supply device that was previously installed in the component mounting device with a tape-type component supply device that is suitable for the production of the switched model board unit. There is. In such a case, there has been proposed a component mounting apparatus having a component supply system in which the replacement is not performed by a field worker looking at a setup table or the like, but is automatically determined on the control device side and a replacement instruction is issued. (For example, see Patent Document 4)
In the case of any of the conventional component mounting apparatuses described above, the component tape components held on the tape holding reel of the tape-type component supply device are sequentially generated during the component mounting operation by the mounting head during the production of the board unit. It will need to be replenished by field workers, since it will decrease and disappear.

  There are two methods for replenishing parts. One is that the part tape of the remaining part is pulled out of the tape holding reel before the parts of the part tape are completely lost, and the old tape holding reel is emptied. In this method, a new tape holding reel full of parts is exchanged, and the rear end of the remaining part tape is connected to the front end of the new part tape. This method is a method with good production efficiency that enables component replenishment without stopping the operation of the component mounting apparatus. This is hereinafter referred to as “tape connection mode”.

Another method of replenishing parts is a method of replacing the tape-type parts supply device as it is. This is because at least two tape-type parts supply devices that hold the same parts on the tape holding reel are prepared in advance, one is placed in the component mounting device at the stage of setup, and the second one is used for replacement when replenishing parts. It is something to prepare. Since this method needs to be performed after the operation of the component mounting apparatus is temporarily stopped, it cannot be said that production efficiency is good as a component replenishment method. This is hereinafter referred to as “cassette exchange mode”. This is a work mode name that comes from the fact that a tape-type component supply device is also called a tape feeder or a tape cassette in a factory.
Japanese Patent Laid-Open No. 10-254528 (paragraphs [0002] to [0004], FIG. 5) JP-A-11-186794 (paragraphs [0002] to [0004], [0015] to [0026], FIGS. 1 and 2) Japanese Patent Laying-Open No. 2003-078284 (paragraphs [0002] to [0004], FIG. 3) Japanese Unexamined Patent Publication No. 05-013988 (paragraphs [0016] to [0018], FIGS. 1 and 3, paragraphs [0022] to [0024], FIG. 6)

  By the way, conventionally, when replenishing the components of the tape-type component supply device as described above, the site worker should replenish the components while patroling and monitoring each device on the board unit production line. Replenishment of components has been performed by judging the supply device and the time for replenishment thereof visually or by warning notification issued by the component mounting device.

  In this way, the location of the tape-type component supply device that should be replenished and the replenishment timing were determined by visual confirmation of the on-site worker and warning notification issued by the component mounting device. When it was not possible to do this, or when the parts replenishment time of multiple tape-type parts supply devices overlapped, the parts replenishment work was not in time, and the operation of the component mounting apparatus was stopped and the operating rate was often reduced. .

  In view of the above-described conventional situation, an object of the present invention is to provide an electronic component replenishment system for an electronic component mounting apparatus that prevents operation from being stopped for component replenishment as much as possible and improves component mounting work efficiency. That is.

The configuration of the electronic component replenishment system for the electronic component mounting apparatus according to the present invention will be described below.
An electronic component replenishment system for an electronic component mounting apparatus according to the present invention includes a notice list generating means for generating a notice list for notifying the timing of tape connection work of a component tape of a tape-type component supply apparatus, and a notice list generating means. The notice list transmitting means for transmitting the generated notice list to the wireless terminal of the field worker participating in the production line, and the parts replenishment mode based on the parts replenishment mode switching signal transmitted from the wireless terminal are held in tape. It is configured to have a replenishment mode switching means for switching between a tape connection mode in which reels are replaced with new ones and old and new component tapes are connected, and a cassette replacement mode in which the tape-type component feeder itself is replaced.

  The electronic component replenishment system of the electronic component mounting apparatus further includes warning transmission means for transmitting a warning signal for notifying that the timing of electronic component replacement work is approaching the wireless terminal based on the notice list, for example. In addition, for example, when the remaining length of the component tape of the tape-type component supply device reaches the minimum tape length necessary for the tape connection work, the component suction from the tape-type component supply device is stopped. It further comprises a component suction stop means.

  According to the present invention, a warning for approaching parts replacement time is transmitted to a wireless terminal of a field worker participating in the production line based on a preliminary list of parts replacement time created in advance. By carrying the terminal, it is possible to know the warning of approaching the parts replacement time everywhere, so that it is not necessary to perform a patrol monitoring in order to know the position and time of parts replenishment, and the work efficiency is improved.

  In addition, because the wireless terminal can receive the advance notice list of parts replacement time, it is possible to list the parts that need to be replenished by the advance notice list displayed on the wireless terminal, so that field workers can easily grasp the parts to be replenished. It is convenient and improves work efficiency.

  In addition, since the replenishment method for parts that require replenishment can be changed from the wireless terminal, the site worker can specify the most efficient part replenishment method that is suitable for the current situation at the site, thereby making it possible to stop the operation as much as possible. It is possible to improve the work efficiency by restraining to the above.

If there are a plurality of mounting coordinates for the same component, the number of coordinates is the number of mounting the same component on the board. This mounted parts table constitutes part of the parameters of the component mounting program together with various data related to the tape-type component supply device.

  Subsequently, the component mounting process program is optimized based on the mounted component table (S6). This optimization is based on the arrangement of the tape-type component supply device on the stage, and the tape that accommodates the component to be mounted at the mounting position at the position on the stage closest to the component mounting position of the board carried into the component mounting apparatus. To place a component-type component supply device, to pick up the components of the tape-type component supply device with the mounting head closest to the tape-type component supply device, and to pick up two components simultaneously with two mounting heads Component mounting taking into account considerations such as deciding how to do this, and determining the mounting order of each component so that the four work heads can continue mounting work without interfering as much as possible without interfering with each other To assemble instruction commands of the processing program.

  When this program optimization is completed, it is fed back to the production plan, and based on the feedback, the production time is calculated and displayed on the display screen (S7), and the optimized component mounting processing program is stored in the line management device. 4 is transmitted to each mounter (component mounting apparatus 2) via the LAN of the signal line 3 (S8). Receiving this transmission, the CPU 30 of the component mounting apparatus 2 first starts a confirmation operation of the component supply apparatus (S9).

  First, here, a part supply setting operation is performed by an on-site worker (S10). This setting operation is performed by attaching a tape-type component supply device 19 in which a component tape of a component to be supplied is accommodated in a tape holding reel 21 to a predetermined position of a supply stage 18 specified by parameters of a component mounting processing program. is there.

  After attaching the tape-type component supply device 19, the field worker 5 inputs the number of the supply stage 18, the number of the attachment position, and the component coat accommodated in the tape-type component supply device 19 from the operation input display device 14. To do. If it is a compatible part, a confirmation (OK) notification is given to the field worker 5 from the component mounting apparatus 2, and if it is an inappropriate part, NG is notified. When all the tape-type component supply devices 2 are confirmed, the production start OK is notified.

  Here, the field worker 5 inputs an instruction to start automatic production (S11). With this instruction input, the board unit production line starts operation, the board is supplied, components are mounted on the board, and the production of the board unit proceeds.

  Here, in each tape-type component supply device 19, when the remaining amount of the components accommodated in the tape holding reel 21 is reduced and the component expiration time approaches, the component expiration timing from the tape-type component supply device 19 is reached. An approach notification (preliminary signal) is transmitted to the line management device 4, and the line management device 4 creates the preliminary notification list 65 shown in FIG. 4, and the preliminary notification signal is transmitted via the wireless access point 7 together with the preliminary notification list 65. Transmit to the terminal 6.

  Upon receipt of this notice signal, the site worker 5 starts a component replenishment operation (S12). In this component replenishment operation, it is checked whether the component of the component tape connected to the tape or the component of the replaced tape-type component supply device is appropriate (OK) or inappropriate (NG) ( S13) If OK, the production of the substrate unit proceeds. The above-described component replenishment will be described later in detail.

  As the production of the board unit proceeds, the production status is displayed (S14). This display is automatically displayed on the monitor device 11 of the component mounting apparatus 2 and also displayed on the display screen of the wireless terminal 6 as necessary.

When the number of board units designated in the production plan is produced, the production is finished (S15).
FIG. 9 is a work process chart for explaining the processing performed in the component replenishment mode and the worker's work contents, the corresponding wireless terminal 6, the component mounting apparatus 2, and the line management apparatus 4 in this example. As shown in the figure, the work process table 67 includes a current part replenishment mode 67-1, an operator's work contents 67-2, 67-3 when there is no notice for each part replenishment mode and work contents, and there is a notice. Case 67-4.

  The current parts replenishment mode 67-1 includes two work modes, a tape connection mode and a cassette exchange mode. The work contents 67-2 for the two work modes are respectively changed to a refill mode change and a tape. There are three work contents: connection replenishment and cassette replacement replenishment. That is, there are six types of work contents as a whole. In these six types of work contents, the work contents differ from a to l except for a part in 67-3 without notice and 67-4 with notice, respectively.

  First, when the parts replenishment mode 67-1 is the tape connection mode and the work content 67-2 of the worker is a change of the replenishment mode, the work content a in the case of no notice 67-3 is that the mode cannot be changed. is there. In other words, it is set so that the mode cannot be changed in the program specifications.

  On the other hand, in the work content b in the case of the notice 67-4, the worker 5 selects the target tape-type component supply device 19 whose replenishment mode is to be changed from the notice list 65 displayed on the display screen of the portable terminal 6. Then, an instruction to change to the cassette exchange mode is input and transmitted. When receiving the change instruction, the CPU 30 of the component mounting apparatus 2 changes the data of the component replenishment mode of the tape-type component supply device 19 held in the apparatus from the tape connection mode to the cassette replacement mode.

  Next, when the component replenishment mode 67-1 is the tape connection mode and the work content 67-2 of the worker is the tape connection replenishment, the work content c in the case of 67-3 without notice performs the tape connection replenishment. The tape-type component supply device 19 is not displayed in the notice list 65 because there is no notice. Accordingly, the operator 5 forcibly designates a desired tape-type component supply device 19 feeder from the arrangement data of the tape-type component supply device 19, checks the consistency of the components to be replenished, and then replenishes the tape connection. After completing the component replenishment, the wireless terminal 6 inputs and transmits a component replenishment completion instruction. When the completion instruction is received, the CPU 30 of the component mounting apparatus 2 updates the remaining number of parts of the tape type component supply apparatus 19 stored as a parameter of the mounting program.

  On the other hand, in the work content d in the case of the notice 67-4, first, the tape-type component supply device 19 exists in the notice list 65 displayed on the display screen of the wireless terminal 6 by the notice notice. The operator 5 selects the tape-type component supply device 19 from the notice list 65 or specifies the tape-type component supply device 19 from the arrangement data of the tape-type component supply device and checks the consistency of the components to be replenished. After that, the tape connection is replenished. After completing the component replenishment, the wireless terminal 6 inputs and transmits a component replenishment completion instruction.

  Upon receipt of the component replenishment completion instruction, the CPU 30 of the component mounting device 2 updates the remaining number of components of the tape-type component supply device 19 stored as a parameter of the mounting program, and further, by turning on or blinking the alarm lamp 12 Cancel the alarm processing that was being performed. Further, the CPU 57 of the line management device 4 deletes the data record of the tape type component supply device 19 from the notice list 65 transmitted to the wireless terminal 6.

  Also, when the parts replenishment mode 67-1 is the tape connection mode and the work content 67-2 of the operator is cassette replacement replenishment, the work content e in the case of no notice 67-3 is the tape connection mode. This is a case where the operator 5 mistakenly or intentionally performs cassette replacement replenishment. Since there is no notice, the tape-type component supply device 19 does not exist in the notice list 65 of the wireless terminal 6. Accordingly, the operator 5 forcibly designates the tape-type component supply device for replenishing the component based on the arrangement data of the tape-type component supply device, checks the consistency of the component to be replenished, and then replenishes the cassette. After completing the replenishment of parts, the wireless terminal 6 sends an instruction to complete the replenishment of parts by key input. When the completion instruction is received, the CPU 30 of the component mounting apparatus 2 updates the remaining number of parts of the tape type component supply apparatus 19 stored as a parameter of the mounting program.

  On the other hand, the work content f in the case of 67-4 with a notice is a case where the operator mistakenly or intentionally performs cassette replacement and replenishment even in the tape connection mode. In this case, since there is a notice, the tape-type component supply device 19 exists in the notice list 65 on the display screen of the wireless terminal 6. The worker 5 selects the corresponding tape-type component supply device 19 from the notice list 65, or forcibly designates the tape-type component supply device 19 based on the arrangement data of the tape-type component supply device, and refills the component. After checking the consistency of the cassette, replenish cassette replacement. After the component replenishment is completed, the wireless terminal 6 sends a key for a component replenishment completion instruction. Upon receipt of the component replenishment completion instruction, the CPU 30 of the component mounting device 2 updates the remaining number of components of the tape-type component supply device 19 stored as a parameter of the mounting program, and further, by turning on or blinking the alarm lamp 12 Cancel the alarm processing that was being performed. Further, the CPU 57 of the line management device 4 deletes the data record of the tape type component supply device 19 from the notice list 65 transmitted to the wireless terminal 6.

  Next, when the parts replenishment mode 67-1 is the cassette replacement mode and the work content 67-2 of the operator is a change of the replenishment mode, the work content g in the case of 67-3 without notice is the tape connection mode. This is the same as in the case of the change a of the supplement mode of work contents.

  On the other hand, in the work content h in the case of 67-4 with a notice, the worker 5 selects a tape-type component supply device whose replenishment mode is to be changed from the notice list 65 of the portable terminal 6 and changes the tape connection mode to the tape connection mode. Key in instructions and make a call. When receiving the change instruction, the CPU 30 of the component mounting apparatus 2 changes the data of the component replenishment mode of the tape type component supply device 19 held in the apparatus from the cassette replacement mode to the tape connection mode.

  Next, when the parts replenishment mode 67-1 is the cassette replacement mode and the work content 67-2 of the operator is tape connection replenishment, the work content i in the case of no notice 67-3 is the cassette replacement mode. In this case, however, the operator 5 mistakenly or intentionally replenishes the tape connection. Since there is no notice, the tape-type component supply device 19 does not exist in the notice list 65 of the wireless terminal 6.

  The operator forcibly designates the tape-type component supply device intended for component replenishment from the arrangement data of the tape-type component supply device, checks the consistency of the components to be replenished, and performs tape connection replenishment. After completing the component replenishment, the wireless terminal 6 inputs and transmits a component replenishment completion instruction. The CPU 30 of the component mounting apparatus 2 that has received the completion notification updates the remaining number of components of the tape-type component supply device of the program parameter.

  On the other hand, the work content j in the case of 67-4 with a notice is a case where the operator mistakenly or intentionally replenishes the tape connection even in the cassette exchange mode in this case. Since there is a notice, the tape-type component supply device 19 exists in the notice list 65 of the wireless terminal 6. The operator 5 selects the tape-type component supply device 19 from the notice list 65 or forcibly designates the tape-type component supply device from the arrangement data of the tape-type component supply device, and the consistency of the components to be replenished After checking, replenish the tape connection. After completing the component replenishment, the wireless terminal 6 inputs and transmits a component replenishment completion instruction. When the completion instruction is received, the CPU 30 of the component mounting apparatus 2 updates the remaining number of parts of the tape-type component supply apparatus of the program parameter, and cancels the alarm processing that has been performed by turning on or blinking the alarm lamp 12. Further, the CPU 57 of the line management device 4 deletes the data record of the tape type component supply device 19 from the notice list 65 transmitted to the wireless terminal 6.

  Next, when the parts replenishment mode 67-1 is the cassette replacement mode and the work content 67-2 of the operator is the cassette replacement replenishment, the work content k in the case of no notice 67-3 is first without notice. Therefore, there is no tape-type component supply device 19 that the operator 5 intends to replenish components in the notice list 65 of the wireless terminal 6. Accordingly, the operator 5 forcibly designates the tape-type component supply device 19 intended for component replenishment based on the tape-type component supply device arrangement data, checks the consistency of the component to be replenished, and then replenishes the cassette. After completing the replenishment of parts, the wireless terminal 6 inputs and sends an instruction to complete the replenishment of parts. The CPU 30 of the component mounting apparatus 2 that has received the component replenishment completion instruction updates the remaining number of components of the tape type component supply device of the program parameter.

  On the other hand, since the work content i in the case of the notice 67-4 has a notice, the notice type list 65 of the wireless terminal 6 includes the tape-type component supply device 19 corresponding to the notice. After the operator 5 selects the corresponding tape-type component supply device 19 from the notice list 65 or designates the corresponding tape-type component supply device from the tape-type component supply device arrangement data and checks the consistency of the components to be replenished Then, replenish cassette replacement. After the replenishment is completed, the wireless terminal 6 transmits a part replenishment completion instruction by key input. The CPU 30 of the component mounting apparatus 2 that has received the completion instruction updates the remaining number of parts of the corresponding tape type component supply apparatus 19 of the program parameter, and simultaneously cancels the alarm processing. Further, the CPU 57 of the line management device 4 deletes the data record of the tape type component supply device 19 from the notice list 65 transmitted to the wireless terminal 6.

  FIG. 10 (a) is a flowchart showing the processing operation in the component mounting apparatus 2 limited to processing for component replenishment in the production process described above, and FIG. 10 (b) is a line management device similarly limited to processing for component replenishment. 4 is a flowchart for explaining a processing operation of No. 4;

  The processing operations shown in (a) and (b) of FIG. 9 supplement the description of the processing operation of each apparatus described with reference to FIGS. 7 and 8 accompanied by the work contents of the field worker described with reference to FIG. In addition, the processing operation of the electronic component replenishment system of the electronic component mounting apparatus of the present invention is completed by supplementing the processing operation shown in FIGS. 10 (a) and 10 (b).

  Further, the process shown in FIG. 10 (a) is a process performed under the control of the CPU 30 for each component mounting apparatus 2 on the board unit production line. In FIG. 10 (a), the production of the board unit is performed. When started (see S11 in FIG. 8), the CPU 30 of the component mounting apparatus 19 (hereinafter simply referred to as CPU 30) determines whether or not the remaining number has been updated while sequentially performing the component mounting process on the board (S101). ).

  This process is performed in any of the tape-type component supply devices 19 arranged on the supply stage 18 of the device itself, with the work contents of 67-3 without notice or 67-4 with notice in the work process chart 67 of FIG. This is a process of determining whether or not the component replenishment described in the above item is performed and an instruction to complete the component replenishment is transmitted from any of the wireless terminals 6.

If the remaining number has not been updated yet (S101: NO), the component replenishment mode is subsequently determined (S102).
In this processing, the component replenishment mode preset in a predetermined storage area of the recording device 47 in the apparatus for each tape-type component supply device 19 in advance is “tape connection mode” or “cassette replacement mode”. It is a process to refer to.

  In addition to the above-described component replenishment mode, a predetermined storage area of the recording device 47 includes a warning signal for a component tape attached to the tape holding reel 21 of the tape-type component supply device 19 in the tape connection mode. Stores data indicating the remaining tape length to be transmitted and data indicating the length to which the supply of components should be stopped (the remaining length of the component tape is necessary for connection with a new component tape). Yes.

  Similarly, data indicating the remaining number of parts to which a notice signal of a part tape attached to the tape holding reel 21 of the tape type part supply apparatus 19 in the cassette exchange mode is to be transmitted is stored. .

Following the above, the CPU 30 determines whether it is an alarm threshold (S103).
When the component replenishment mode determined in S102 is “tape connection mode”, this process refers to data indicating the remaining tape length to which a component tape notice signal should be transmitted, and the current remaining tape length is This is a process for determining whether or not the remaining tape length to which a warning signal should be transmitted has been reached. When the component replenishment mode determined in S102 is the “cassette replacement mode”, a warning signal for the component tape is transmitted. This is a process for determining whether or not the current remaining number of parts has reached the remaining number of parts to which a warning signal is to be transmitted, by referring to the number of parts to be calculated.

If the current remaining tape length or the remaining number of parts has not reached the alarm threshold (NO in S103), it is next determined whether or not the planned number of substrates is satisfied (S104).
This processing is performed by adding the current board number to the board unit production number determined at the time (see S8 in FIG. 8) when the component mounting processing program optimized based on the planned production plan is transmitted to the component mounting apparatus. This is a process for determining whether the total number of unit production has been reached.

  If the total number of board unit productions has not reached the predetermined number of board unit productions (S104 is NO), the process returns to S101 and the processes after S101 are repeated.

  The current remaining tape length or the number of remaining parts has reached the alarm threshold in the determination of the above-described processing S103, that is, the preset remaining tape length or the remaining number of parts referred to based on the current component replenishment mode. Is reached (S103 is YES), an alarm is transmitted (S106).

  The alarm transmitted in this process is the same as the “notice signal” described in FIG. 7 and the “notice” described in FIG. Thereby, parts replenishment work by the field worker 5 is performed. The part replenishment work by the field worker 5 is completed, and a part replenishment completion instruction is keyed and transmitted from the wireless terminal 6.

  In the determination of step S101 in FIG. 10A, the component replenishment completion instruction is received by the component mounting apparatus 2 as a component remaining number update instruction. The CPU 30 determines that the remaining number has been updated (YES in S101). In this case, the remaining number of parts of the tape-type part supply device 19 is set to the initial value, that is, the parts attached to the new tape holding reel 21. The setting is returned to the number of parts packed on the tape (S105), and the process proceeds to step S102.

  On the other hand, in the line management device 4, under the control of the CPU 57, an alarm management server (software) shown in FIG. First, the alarm management server determines whether or not an alarm (notice signal) transmitted from any of the component mounting apparatuses 2 has been received (S201). If there is no incoming alarm (NO in S201), it is further determined whether or not there is a supplemented part (S203).

  In the process for determining whether or not there is a supplemental part, the part supplement described in the contents of work 67-3 without notice or 67-4 with notice in the work process table 67 of FIG. This is processing for determining whether or not a call is transmitted from any one of the wireless terminals 6.

  If there is no replenished component, that is, if no component replenishment completion instruction is transmitted from any of the wireless terminals 6 (NO in S203), the process returns to step S201 to repeat the steps after step S201.

  On the other hand, if it is determined in step S201 that the warning signal has been received (YES in S201), registration in the alarm list is performed based on the received warning signal (S202).

  In this process, one record (65a, 65b,...) To the notice list 65 shown in FIG. 5 is generated and recorded every time a notice signal arrives. It is transmitted to the wireless terminal 6. As a result, the parts replenishment work described in 67-4 with a notice in the work process table 67 of FIG. 9 is performed by the field worker 5, and a completion instruction for parts replenishment is transmitted from the wireless terminal 6.

  Thereby, the alarm management server determines that there is a replenished part in the determination in the above-described process S203 (YES in S203). In this case, the work content corresponding to the notice 67-3 regardless of whether or not the parts are replenished in a replenishment mode different from the part replenishment mode registered in the replenishment form 65-7 of the notice list 65. Since the parts are being replenished, the data record relating to the tape-type parts supply device is registered in the notice list 65. Therefore, the alarm management server deletes the record from the notice list 65 (S204).

  In addition, regardless of whether or not parts have been replenished in a replenishment format different from the part replenishment mode registered in the replenishment format 65-7 of the notice list 65, the parts can be replenished with the work content corresponding to 67-2 without notice. If it has been performed (also in this case S203 is YES), the process of step S204 is skipped.

  In this way, in the present invention, parts can be replenished by an alarm notification from the wireless terminal even if the site worker does not monitor the tape-type parts supply device for running out of parts by visual inspection. Work becomes easier and work efficiency is improved.

  In addition, as long as the site worker can perform the component replenishment in the tape connection mode, the component replenishment in the tape connection mode that does not temporarily stop the component mounting device can be performed by the notice of the notice from the line management device. , Improve line productivity.

  In addition, when the parts replenishment timing is too high and the part replenishment work of the field worker is not in time, the parts replenishment mode can be easily switched to the parts replenishment in the cassette replacement mode in which the component mounting apparatus is temporarily stopped by the wireless terminal. This makes it convenient for field workers to concentrate on replenishment work with peace of mind.

  In addition, when there is enough work for the field worker, it is easy to switch from the component replacement mode of the cassette replacement mode to the tape connection mode, so always keep working in an efficient component replacement mode that does not waste time. This improves the productivity of the line.
