  According to the above inventions [1], [4], [5], [6], and [7], the feeder ID of the feeder to be mounted on the mounting machine and the component assembly or the like are attached in advance to the component assembly. By comparing a combination with a general part ID with a combination stored in advance, it is estimated that the part aggregate set in the feeder has not been replaced and the remaining part number has not changed. Since the remaining number of parts stored in advance in association with the combination is used as the remaining number of parts of the feeder, it is not necessary to attach a barcode or the like for identifying each part assembly to each part assembly.

Each head 41 is driven in the vertical direction (Z-axis direction) by an elevating mechanism using a Z-axis servomotor as a drive source, and is rotated in a rotation direction (R-axis direction) by a rotary drive mechanism using an R-axis servomotor as a drive source. ) To be driven. A suction nozzle is provided at the tip of each head 41..., So that a negative pressure is supplied to the suction nozzle from a negative pressure supply means (not shown) at the time of component suction so that the electronic component can be sucked by the suction force of the negative pressure. It has become.

  Reel 36 as a component assembly as shown in FIG. 3 is detachably mounted on each tape feeder 31. The reel 36 is wound with a tape 361 storing small pieces of components such as an IC, a transistor, and a capacitor at predetermined intervals, and the tape 361 is placed in a state where the reel 36 is set on the tape feeder 31. The components that are intermittently drawn from the reel 36 toward the tip of the tape feeder 31 and stored in the tape 361 can be picked up by the head unit 40.

  On the outer surface of the reel (component assembly) 36, a recording medium 362 on which a component ID for identifying the type of the stored component is recorded, and the initial number of components stored in the reel 36 are indicated. A recording medium 363 on which initial number information is recorded is attached in advance by, for example, a component manufacturer. In this embodiment, these recording media 362 and 363 are composed of a tape on which a barcode indicating a component ID and initial number information is printed. The reel 36 that is a consumable item is not particularly given information for identifying each reel individually.

  Further, as shown in FIG. 4, a recording medium 311 on which a feeder ID capable of individually identifying each tape feeder 31 is recorded in the mounting line 90 is attached to the outer surface of each tape feeder 31. .

Is attached. In this embodiment, the recording medium 341 is also composed of a tape on which a barcode indicating the set position ID is printed.

  FIG. 6 is a functional block diagram showing the configuration of the control unit 50 of the mounting machine 10 and the general controller 60 that functions as a remaining component number management apparatus.

  In terms of hardware, the general controller 60 includes an external storage unit such as a CPU, a memory, and a hard disk device, an input unit such as a keyboard and a mouse, an image display unit such as a CRT and a liquid crystal display device, and an interface unit with the mounting machine 10 and the like. Further, it is composed of a personal computer or the like provided with a barcode reader 621 or the like that reads a barcode as a part of the input unit, and functions as a feeder database 61, ID information acquisition means 62, database verification means 63, database registration means 64, etc. Is configured on this computer.

  Each of these functions is provided by a program that can be read by a computer constituting the overall controller 60. This program is loaded into this computer via a recording medium such as a CD-ROM, DVD-ROM or floppy disk, or a network line such as a LAN or the Internet.

  The feeder database (feeder state storage means) 61 stores the current state of each of the feeders 31 under the jurisdiction of the mounting line 90. Specifically, the feeder ID for identifying each feeder 31 and each feeder The component ID for identifying the type of the component supplied by the component assembly 36 set to 31 and the remaining number of components in the component assembly 36 set to the feeder 31 are stored in association with each other. The feeder database 61 stores the current status of each feeder regardless of whether each feeder 31 is mounted on the mounting machine 10 or not. FIG. 7 shows an example of the stored contents of the feeder database.

  The ID information acquisition means 62 includes a feeder ID assigned to the feeder 31 attached to the mounting machine 10 and the feeder when the feeder arrangement is confirmed before the start of production in the mounting machine 10 or at the time of setup change. The part ID assigned to the part assembly 36 set to 31 and the initial number information of the parts attached to the part assembly 36 are acquired. In this embodiment, as shown in FIGS. 3 to 5, the feeder ID, the component ID, and the initial entry number information are recorded on the barcodes printed on the recording media 311, 362, and 363, respectively. The acquisition unit 62 reads the feeder ID and the like by a bar code reader 621 capable of wireless communication with the general controller 60.

  The ID information acquisition unit 62 also reads the set position ID attached to each feeder set position 34 by the bar code reader 621.

  The database collation means (collation means) 63 collates the combination of the feeder ID and the component ID read from the feeder 31 mounted on the mounting machine 10 with the stored contents of the feeder database 61. Specifically, as will be described later, first, it is confirmed whether or not the read feeder ID is stored in the feeder database 61, and if the feeder ID is stored, the component associated with the feeder ID is stored. Whether the ID matches the read component ID is collated.

  The database registration means 64 manages the stored contents of the feeder database 61.

  Specifically, when the feeder ID read from the feeder 31 mounted on the mounting machine 10 is not stored in the feeder database 61, the database registration unit 64 has not yet been managed by this line 90. New registration processing is performed as a new feeder. In this new registration process, data associated with the read feeder ID, the component ID, and the initial entry number indicated by the initial entry number information as the remaining component number are newly registered in the feeder database 61.

  The database registration unit 64 stores the read feeder ID in the feeder database 61. When the component ID stored in association with the feeder ID is different from the read component ID, the feeder 31 Assuming that a new reel (part assembly) 36 is set, the update registration processing is performed on the data of the feeder 31. In this update registration process, the component ID and the remaining component number stored in association with the read feeder ID are updated and registered to the initial component number indicated by the read component ID and the initial component number information.

  The database registration unit 64 functions as a feeder state update unit by performing these new registration processing and update registration processing.

  Further, the database registration unit 64 is configured so that the feeder 31 in which a failure or part breakage occurs during the production from the mounting machine 10 when the production of a certain product (printed circuit board) in the mounting machine 10 is completed or the setup change is performed. When the component is removed, the component remaining number of each feeder 31 stored in the feeder database 61 is updated based on the real-time component remaining number of each feeder 31 managed by the control unit 50 on the mounting machine 10 side. The remaining parts number update registration process is performed. The component remaining number update registration process is a process of registering a result obtained by subtracting the component remaining number of each feeder 31 managed in real time on the mounting machine 10 side with the production of the product (printed circuit board) in the mounting machine 10. The database registration unit 64 functions as a subtraction processing unit by performing the component remaining number update registration process.

  If the combination of the feeder ID and the component ID read by the ID information acquisition unit 62 has not changed from the state when it is stored in the feeder database 61 before confirmation of the feeder arrangement, it is set in the feeder 31. Therefore, the database registration means 64 does not change the stored contents of the feeder database 61, and the feeder database 61 is checked before the feeder arrangement is confirmed. The number of remaining parts stored in association with the combination is used as the current remaining number of parts of the feeder.

  The control unit 50 of the mounting machine 10 also includes, in terms of hardware, an external storage unit such as a CPU, a memory, and a hard disk device, an input unit such as a keyboard and a mouse, an image display unit such as a CRT and a liquid crystal display device, and the mounting machine 10. The functions of the mounting operation control means 51, the component remaining number management table 52, the table update means 53, the alarm notification means 54, etc. are configured on this computer. Yes.

  Each of these functions is provided by a program readable by a computer constituting the control unit 50. This program is loaded into this computer via a recording medium such as a CD-ROM, DVD-ROM or floppy disk, or a network line such as a LAN or the Internet.

  The mounting operation control means 51 controls each servo motor, component recognition camera, etc. according to predetermined substrate data (production program), and controls a mounting operation for mounting a large number of electronic components on the printed circuit board P.

  The component remaining number management table 52 includes, for each feeder set position 34 of the mounting machine 10, the feeder ID of the installed feeder 31, the component ID of the component assembly 36 set in the feeder 31, and the real time. The number of remaining parts of each feeder 31 that changes (decreases) to is stored and managed. FIG. 8 is an example of the storage contents of the remaining component number management table.

  The stored contents of the remaining component number management table 52 are set position IDs and feeders read by the ID information acquisition means 62 when the feeder arrangement is confirmed before the start of production in the mounting machine 10 or at the time of setup change. The remaining number of parts stored in the feeder database 61 corresponding to the combination of the ID and the part ID and the feeder ID and the part ID is acquired by being transmitted from the general controller 60.

  As described above, when the combination of the read feeder ID and the component ID has not changed from the combination stored in the feeder database 61, the number of remaining components stored before the confirmation of the feeder arrangement is determined by this component. Also in the remaining number management table 52, it becomes an initial value of the remaining number management.

  In addition, when the production of a certain product (printed circuit board) in the mounting machine 10 is completed and a setup change is performed, or when the feeder 31 in which a failure or a part has run out during the production is removed from the mounting machine 10, etc. The current component remaining number information of each feeder 31 managed in the component remaining number management table 52 is transmitted to the general controller 60 and used for the above-described component remaining number update registration process.

  The table updating unit 53 manages the remaining number of parts according to the number of parts supplied from the feeder 31 mounted at each set position 34 of the mounting machine 10 in accordance with the production of the product (printed circuit board) in the mounting machine 10. The remaining number of parts at each set position 34 stored and managed in the table 52 is subtracted. The subtraction processing by the table updating means 53 is performed in real time every time a part is picked up from each feeder 31 and used, and the remaining part number management table 52 can always grasp the current remaining part number. Yes.

  The alarm notification means 54 displays a component outage warning to the operator when the current number of remaining components of each feeder 31 stored and managed in the component remaining number management table 52 reaches a predetermined component outage warning standard. This is notified by a display or buzzer sound. As the part-out warning standard, in addition to the specific remaining part quantity, the number of products that can be produced according to the number of parts used for production of each product, the expected part-out time, and the like can be appropriately adopted.

  Next, the procedure of the component remaining number management method of the mounting machine will be described.

  FIG. 9 is a flowchart showing the procedure of the component remaining number management method of the mounting machine.

  As shown in this figure, in this method for managing the remaining number of parts, each feeder 31 mounted on the mounting machine 10 is checked when the feeder arrangement is confirmed before the start of production in the mounting machine 10 or at the time of setup change. The feeder ID, component ID, initial number of pieces, and set position ID are sequentially read by the ID information acquisition means 62 (S11), and whether or not the feeder ID read by the database collating means 63 is stored in the feeder database 61. Is confirmed (S12).

  If the read feeder ID is not stored in the feeder database 61 (NO in S12), the feeder 31 sets the read feeder ID, the component ID, and the initial entry number indicated by the initial entry number information as a new feeder. The remaining number is newly registered in the feeder database 61 in association with each other (S13).

  The read feeder ID is stored in the feeder database 61 (YES in S12), but if the component ID stored in association with this is different from the read component ID (NO in S14). The feeder 31 is presumed that a new reel (part assembly) 36 is set, and the feeder ID is associated with the read part ID and the initial number indicated by the initial number information as the remaining number of parts. It is updated and registered in the database 61 (S15).

  If the combination of the read feeder ID and the component ID is stored in the feeder database 61 (YES in S12 and S14), the component assembly 36 set in the feeder 31 is not replaced, and the component Assuming that there is no change in the remaining number, the stored contents of the feeder database 61 are not changed.

  Subsequently, the remaining component count stored in the feeder database 61 for this feeder 31 is loaded into the remaining component count management table 52 on the mounting machine 10 side together with the read feeder ID, component ID, and set position ID. (S16).

  The above processes are repeated for all the feeders 31 mounted on the mounting machine 10 (NO in S17).

  If reading of feeder IDs and the like is completed for all feeders (YES in S17), production of the product (printed circuit board) is started as appropriate (S18), and the parts are taken out from each feeder 31 and used for production. Each time the remaining number of parts in the remaining part number management table 52 is subtracted by the table updating means 53 (S20), and if the remaining part number in the remaining part number management table 52 is less than or equal to the predetermined warning number (YES in S21). A predetermined part-out warning is displayed to the operator (S22).

  When the production of the predetermined number of products scheduled in this way is completed (YES in S19), the remaining component number information of each feeder 31 managed in real time in the remaining component number management table 52 on the mounting machine 10 side is obtained. The part remaining number update registration processing is performed for the remaining part number of each feeder ID transmitted to the general controller 60 side and stored in the feeder database 61 by the database registration unit 64, and the series of remaining part number management ends. .

  According to the method for managing the number of remaining parts of the mounting machine as described above, the feeder ID of the feeder 31 to be mounted on the mounting machine 10 and the general part ID that is attached in advance to the parts assembly by a parts manufacturer or the like. By checking the combination with the combination stored in advance in the feeder data table 61, it is estimated that the component assembly 36 set in the feeder 31 has not been replaced and the remaining number of components has not changed, Since the remaining number of parts stored in advance in association with this combination is used as the remaining number of parts of the feeder 31, it is not necessary to attach a barcode or the like for identifying each part assembly 36 to each part assembly 36. The number of remaining parts of each feeder 31 can be easily managed.

  Further, when the feeder ID is not stored in the feeder data table 61 and the feeder is estimated to be a new feeder, or the feeder ID is stored, the component ID associated therewith is the component ID. Since it is different from the one read from the assembly 36, when it is estimated that the component assembly 36 has been replaced from the feeder 31, it is generally the initial stage that the component assembly is preliminarily attached to the component assembly. Since the number information is read and used as the remaining part number of the feeder 31, the initial value of the remaining part number management when the part assembly 36 is replaced from the feeder 31 can be easily obtained.

  Further, the number of remaining parts of each feeder 31 is acquired from the overall controller 60 side before the production starts on the mounting machine 10 side, and the remaining number of parts in real time according to the number of parts supplied from each feeder during production. Is subtracted and the part-out warning is performed based on a predetermined warning criterion, so that it is possible to prevent parts from being out of production during production.

  As mentioned above, although one embodiment was described, you may comprise like this invention.

  (1) In the above-described embodiment, the remaining component number management device is configured on the general controller 60 different from the mounting machine body 10, but may be configured in the mounting machine 10 such as on the control unit 50 provided in the mounting machine 10. Good.

  (2) In the above embodiment, the sticker on which the barcode is printed is given as the recording medium for storing the feeder ID, the component ID, the initial entry number information, the set position ID, and the like, but this recording medium is particularly limited. For example, it may be a recording medium (wireless tag) composed of a minute electronic circuit capable of wireless communication.

  (3) In the above embodiment, the case where the operator manually reads the feeder ID, the component ID, and the like using the barcode reader 621 is described as an example. It may be.

  (4) In the above embodiment, when the combination of the read feeder ID and the component ID is not stored, the initial number read from the component assembly 36 is set as the remaining component number of the component assembly 36. However, when the part assembly 36 in use is set in the feeder 31, the remaining part number field in the feeder database (feeder state storage unit) 61 is left blank, and the remaining part number is not subject to management. Good. Furthermore, if the remaining number of parts in the part assembly 36 in use is recorded, the recorded remaining part number may be input.

  (5) In the above embodiment, it is estimated that the component assembly 36 set in each feeder 31 is not replaced by the combination of the feeder ID and the component ID. However, in addition to the feeder ID and the component ID, the component assembly It may be estimated that the part assembly 36 has not been replaced by a combination including the initial entry number information attached to the body 36. In this way, a higher degree of accuracy is obtained that the part assembly 36 has not been replaced.

  (6) In another embodiment, the tape with the part ID barcode and the initial entry number information barcode attached to the outer surface of the reel (part assembly) 36 is not affixed. It may be the case that a delivery note in which these data are written on the paper is attached to the reel 36. When the reel 36 is assembled into the feeder 31, the operator visually recognizes the feeder ID, the component ID, and the initial entry number information, and inputs the information with the keyboard, so that the feeder ID, the component ID, and the initial entry number information are obtained from the general controller 60 or the mounting machine. 10 control units 50 and stored in the feeder database 61 as one set information. In this case, the initial entry number information is input to the memory area of the remaining part number, and is thereafter handled as the remaining part number. Similarly, when the feeder 31 incorporating the reel 36 is mounted on the mounting machine, the feeder ID, the component ID, or further the initial entry number information is visually recognized by the operator and input with the keyboard. The initial entry number information may be read by the general controller 60 or the control unit 50 of the mounting machine 10.
