The component identification read by the component identification mark reader immediately before Type of parts indicated a, in which mounting of the component cartridge is recognized as a kind of part of the component reels of the cartridge mounting portion is detected.

  According to the present invention, the type of the component reel component held by the operator in the component cartridge is specified by the component identification mark read by the component identification mark reader, and the cartridge mounting portion in which the cartridge is mounted by the cartridge detection sensor. By specifying the part, it is possible to accurately determine in which cartridge mounting part the component cartridge holding the component reel having what component is mounted. In addition, since the component identification mark can be read before being attached to the apparatus main body, there is no fear of reading the component identification mark of another component reel by mistake. Furthermore, since there is no need to provide identification marks indicating the respective positions on the cartridge mounting portion, it is possible to reduce the surface area of the cartridge mounting portion and reduce the size of the apparatus main body.

Embodiment 1 FIG.
FIG. 1 shows a configuration of a component mounting apparatus according to Embodiment 1 of the present invention. The component mounting apparatus shown in FIG. 1 includes an apparatus main body 1, a computer 2, and a barcode reader (part-by-component labeling apparatus) 3. The apparatus main body 1 is provided with a plurality of cartridge mounting portions 4 arranged in a line, and a component cartridge 5 can be mounted on each cartridge mounting portion 4 one by one. Each of the component cartridges 5 can hold a component reel 6 wound with a tape that holds mounted components at regular intervals, and can supply the components on the component reel 6 to the apparatus main body 1. Each component reel 6 has a barcode (component identification mark) 7 indicating the type and lot number of the wound component and the serial number of the component reel 6 attached thereto.

  Each cartridge mounting unit 4 includes a pusher 8 that lifts the component cartridge 5 and a cartridge detection sensor 9 that detects the mounting of the component cartridge 5, and a mounting unit address N that specifies each position is printed. For example, the cartridge detection sensor 9 is turned on when the component cartridge 5 is mounted and turned off when the component cartridge 5 is removed.

  Further, information such as a detection result of the cartridge detection sensor 9 of each cartridge mounting unit 4 is input from the apparatus main body 1 to the computer 2. The computer 2 stores the types of parts of the control unit 10 which is a control means including an arithmetic unit and the part reel 6 held in the part cartridge 5 mounted on each cartridge mounting part 4, for example, a part including a hard disk device. An information storage unit (component information storage means) 11 and a display device 12 including a CRT, a liquid crystal panel, and the like are provided. The computer 2 is connected to a barcode reader 3 that can read the barcode 7, and information read by the barcode reader 3 is input to the computer 2.

  FIG. 2 shows an example of data stored in the component information storage unit 11. This data is a table in which component codes indicating the types of components of the component reel 6 held in the component cartridge 5 corresponding to the mounting unit address indicating the position of the cartridge mounting unit 4 are stored.

  FIG. 3 shows a flow of control of component cut processing by the control unit 10 in the component mounting apparatus configured as described above. This processing is executed when the component mounting apparatus 1 detects that the component reel 6 of the component cartridge 5 of any one of the cartridge mounting portions 4 has been completed, that is, the occurrence of component breakage. Immediately before this processing is executed, it is premised that the component mounting operation is appropriately performed. Therefore, in the product manufactured by the component mounting apparatus, the cartridge mounting unit 4 is stored in the component information storage unit 11. A part code of a necessary part is stored for each (mounting part address).

  When the component out process is executed, first, in step S1, the control unit 10 interrupts the mounting operation of the component mounting apparatus, and causes the display unit 12 to detect the mounting unit address N of the cartridge mounting unit 4 in which the component outage is detected. Is displayed and information for requesting the user to replace the component reel 6 is displayed. At the same time, it is preferable to sound an alarm so that the operator can easily notice. Further, in the present embodiment, the pusher 8 lifts the component cartridge 5 in which the component has run out, so that the component cartridge that requires replacement of the component reel 6 can be easily understood.

  In step S <b> 2, the operator removes the component cartridge 5 from which component breakage has been detected from the component mounting apparatus, and replaces the component reel 6 of the removed component cartridge 5 with a new component reel 6. In step S <b> 3, the operator reads the barcode 7 of the new component reel 6 with the barcode reader 3. The control unit 10 stores the content of data indicated by the barcode 7 read by the barcode reader 3 in the internal memory.

  In step S 4, the operator detects that the component cartridge 5 whose component reel 6 has been replaced is mounted on the cartridge mounting unit 4 by the cartridge detection sensor 9, and stores the mounting unit address in the internal memory of the control unit 10. . When the mounting of the component cartridge 5 is detected, immediately before that, the component code indicated by the data of the barcode 7 stored in step S3 is held in the component cartridge 5 of the cartridge mounting portion 4 whose mounting has been confirmed. The part code of the part reel 6 is determined.

  When a plurality of barcodes 7 are read before the mounting of the component cartridge 5 is detected, since the data read last is stored in the internal memory of the control unit 10, this data is stored in the component reel. 6 information. When the mounting of the component cartridge 5 is confirmed, if a certain time has elapsed since the last time the barcode 7 was read, the barcode 7 may be requested to be read again.

  If the component code of the component reel 6 of the mounted component cartridge 5 is determined, the address at which the mounting of the component cartridge 5 is detected is collated with the component code stored in the component information storage unit 11 in step S5. If the collation results in step S5 match, the component cartridge 5 holding the component reel 6 of the same type as that used for the mounting operation until the component runs out becomes the same cartridge mounting portion 4. Judged to be installed. In this case, it progresses to step S6, the replacement request display of the display apparatus 10 is reset, and the mounting operation of the component mounting apparatus is restarted. However, if the collation results in step S5 do not match, the wrong component reel 6 is attached to the component cartridge 5, so that in step S7, the component reel 6 of the component cartridge 5 just mounted on the display device 12 is displayed. Is displayed, and the operator is requested to replace the component reel 6 again.

  In the present embodiment, in order to confirm the type of the component on the component reel 6, only one confirmation operation is performed for the operator to read the barcode 7 by the barcode reader 3 for each replacement operation of the component reel 6. Request. Since the attachment / detachment of the component cartridge 5 is detected by the cartridge detection sensor 9, it is possible to accurately grasp the address of the cartridge mounting portion 4 where the operator has attached / detached the component cartridge 5. Further, since the barcode 7 is read before the component cartridge 5 is mounted on the cartridge mounting portion 4, there is a risk of making a mistake that the barcode 7 of the component reel 6 held by another component cartridge 5 is erroneously read. Absent. As described above, in the component mounting apparatus of the present invention, the number of times the barcode reader 3 is used is small and the possibility of an operation error is small. Therefore, the time required for confirming the replacement of the component reel 6 is short and the operating rate is not lowered.

Embodiment 2. FIG.
FIG. 4 shows the configuration of the component mounting apparatus according to the second embodiment of the present invention. In the description of the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. Each of the cartridge mounting portions 4 of the apparatus main body 1 of the present embodiment includes a display lamp 13 that can be lit independently. Further, the computer 2 has a volume secured separately from the component information storage unit 11 on the hard disk, for example, and the components to be held in the component cartridge 5 to be mounted on each cartridge mounting unit 4 for each product in which the component is mounted in the component mounting apparatus. A product information storage unit (product information storage means) 14 for storing the types of components of the reel 6 is provided. Furthermore, an input device (input means) 15 such as a keyboard is connected to the computer 2.

  FIG. 5 shows an example of data stored in the product information storage unit 14. This data is stored in association with a product ID that identifies a product on which a component is mounted, a mounting unit address that indicates the position of the cartridge mounting unit 4, and a component code that indicates the type of component of the component reel 6 to be held. It is a table. In this table, data is configured so that one part code can be specified for each mounting part address for each product ID.

  FIG. 6 shows a flow of a mounting operation start process executed at the start of component mounting operation including product switching in the component mounting apparatus according to the present embodiment. First, at the start of the component mounting operation, in step S11, the operator inputs the product ID of the product to be mounted through the input device 15. In step S <b> 12, the control unit 10 reads the input product ID data from the data in the product information storage unit 14 and compares it with the data in the component information storage unit 11. If a mismatch is found in the part code of the same mounting part address between the data in the product information storage part 14 and the data in the part information storage part 11, the appropriate information indicated by the data in the mounting part address and the product information storage part 14 is displayed on the display part 12. The information indicating that the component cartridge 5 holding the component reel 6 of an appropriate component type is mounted is displayed. At the same time, the display lamp 13 of the cartridge mounting unit 4 of the mounting unit address is turned on to clearly indicate to the operator which cartridge mounting unit 4 needs to mount or replace the component cartridge 5.

  The indicator lamp 13 can be visually recognized in the state where the component cartridge 5 is mounted in the vicinity of the component cartridge 5, preferably within 10 cm, so that the mounting portion address can be operated without mistake when the component cartridge 5 is attached or detached. It is desirable to provide as follows.

  The operator holds a predetermined component reel 6 on the component cartridge 5 to be mounted on the cartridge mounting portion 4 whose display lamp 13 is lit, and in step S13, the bar code 7 of the component reel 6 is transferred to the bar code reader 3. Read by. The control unit 10 stores data such as a component code indicated by the read barcode 7.

  If the mounting of the component cartridge 5 is confirmed by the cartridge detection sensor 9 in step S14, the control unit 10 stores the mounting unit address where the mounting of the component cartridge 5 is confirmed. In step S15, the control unit 10 obtains, from the product information storage unit 14, one component code specified by the product ID of the product to be mounted and the mounting unit address where the mounting of the component cartridge 5 is confirmed. Check and compare with the part code indicated by the barcode 7 stored immediately before in step S13, that is, the part code indicating the part type of the part reel 6 held in the part cartridge 5 confirmed to be mounted. To do. If this comparison / collation result does not match, the process proceeds to step S16, where information is displayed on the display device 12 to request replacement of the component reel 6 of the component cartridge 5 that has just been mounted, and the procedure returns to step S13.

  As a result of the comparison in step S15, if the part code indicated by the barcode 7 matches the part code in the product information storage unit 14, the process proceeds to step S17, and the part code of the mounting unit address in the part information storage unit 11 is obtained. Then, the part code is rewritten in step 15 and the display lamp 13 for the mounting portion address is turned off.

  In step S18, it is confirmed whether the data in the component information storage unit 11 and the data of the product ID of the product that performs the mounting operation of the product information storage unit 14 all match. If the component codes of all mounting unit addresses in the component information storage unit 11 do not match the component codes in the product information storage unit 14, the cartridge mounting unit 4 holding the component reel 6 different from the type required for the product. Therefore, the process returns to step S13 to wait for further work by the operator. If the data in the component information storage unit 11 matches the product information storage unit 14 in step S18, the component cartridges 5 holding the component reels 6 of the components necessary for the product are mounted in all the cartridge mounting units 4, respectively. Therefore, the operation of the mounting apparatus is started in step S19.

  In this embodiment, even when the product of the component mounting apparatus is switched, the operator can read the barcode 7 with the barcode reader 3 before mounting the component cartridge 5 on the cartridge mounting portion 4 every time the component reel 6 is replaced. That's fine. For this reason, the barcode 7 of the other component reels 6 is not erroneously read, and the setup work up to the start of operation can be performed in a short time. In addition, since the mounting unit address where the component cartridge 5 is mounted is detected by the cartridge detection sensor 9, it is necessary to reconfirm the position where the component cartridge 5 is mounted, or to reconfirm the defective product by supplying the wrong component. There is no manufacturing.

  Further, at the time of product switching, the data in the component information storage unit 11 and the data in the product information storage unit 14 are collated, and only those that need to hold different component reels 6 in the same cartridge mounting unit 4 are displayed. There is no need to remove the part cartridge 5 that does not require replacement of the part reel 6 and reconfirm the part type.

  Moreover, you may further provide the pusher 8 similar to 1st Embodiment in the component mounting apparatus of this embodiment. Normally, it is necessary to replace the component reels 6 of the plurality of component cartridges 5 at the time of product switching. By pushing up the component cartridge 5 to be replaced with the pusher 8, the operator does not mistake the component cartridge 5 to be replaced. Can be removed. When the operator replaces the component reel 6 of the component cartridge 5, reads the barcode 7 of the component reel 6 and mounts it on the cartridge mounting portion 4, the cartridge detection sensor 9 mounts the component cartridge 5 on the cartridge mounting portion 4 with the correct address. Therefore, the operator is not required to pay more attention than necessary, and the replacement operation of the component reel 6 can be performed quickly.

  Further, each cartridge mounting portion 4 may be provided with an attachment request lamp that is lit when the component cartridge 5 is to be mounted, for example, in the vicinity of the pusher 8. In this case, when the operator reads the barcode 7 of the component reel 6, the control unit 10 mounts the cartridge mounting unit 4 to which the component cartridge 5 holding the component reel 6 of the type of the barcode 7 read is to be mounted. The installation request lamp provided in is turned on. Thereby, it is possible to prevent an operator from making a mistake that the component cartridge 5 is mounted on the cartridge mounting portion 4 having the wrong address.
