The connection unit 25e is a connection unit that is electrically connected to the electronic component mounting machine 20 or is electrically connected to a stand 49a for transmitting (transmitting / receiving) information to / from the component management computer 40. The tape feeder 25 communicates information with the electronic component mounting machine 20 and the component management computer 40 while being connected to the electronic component mounting machine 20 and the stand 49a.

  The acquisition unit 25f (acquisition means) acquires information on the planned mounting position where the tape feeder 25 is mounted from the component management computer 40 via the connection unit 25e. The storage unit 25g (storage unit) stores the planned mounting position information acquired by the acquisition unit 25f. The control unit 25h controls the storage unit 25g to store the planned mounting position acquired by the acquisition unit 25f.

  In addition, the control unit 25h controls the display device 25d to display the planned mounting position information stored in the storage unit 25g. For example, if the mounting position is the mounting position of the tenth tape feeder 25 of the second electronic component mounting machine 20 on the first line 10-1, “1-2-10” is displayed on the display 25d. Is done. Note that the order of the electronic component mounting machine 20 is the order from the upstream in the transport direction, and the mounting position of the tape feeder 25 is the order according to a predetermined arrangement order.

  The control unit 25h is configured to receive the detection result from the mounting sensor 25i and the association information from the acquisition unit 25f, and controls the display of the display unit 25d based on the information.

  Specifically, when replacing the electronic component reel 25b, if the old electronic component reel 25b is removed from the tape feeder 25, the mounting sensor 25i detects that the electronic component reel 25b is not mounted, and the control unit 25h The display 25d displays “Reel is not verified”. Thereafter, when a new electronic component reel 25b is attached to the tape feeder 25, the attachment sensor 25i detects the attachment. Even when the mounting is detected, the control unit 25h continues to display “the reel has not been verified” on the display 25d.

  After that, when the acquisition unit 25f acquires the association information between the new electronic component reel 25b and the tape feeder 25, the control unit 25h cancels the indication that “the reel is not verified” displayed on the display unit 25d. . At this time, “Reel is collated” may be displayed. On the other hand, when the acquisition unit 25f does not acquire the association information of the tape feeder 25, the control unit 25h continues to display “Reel is not verified” displayed on the display 25d.

  It should be noted that the electronic component reel 25b may be exchanged without being set on the stand 49a. In this case, until the association between the electronic component reel 25b after replacement and the tape feeder 25 (main body 25a) is completed (until the association information is acquired), the display unit 25d displays “reel”. Is displayed, the operator needs to set the displayed tape feeder 25 on the stand 49a, perform the association work, and perform the association. When the associating operation is completed and the tape feeder 25 acquires the associating information, the message “Reel is not collated” displayed on the display unit 25d disappears.

  The tape feeder 25 includes a power source 25j (for example, a battery). The power supply 25j supplies power to electrical components such as the control unit 25h, the display 25d, and the mounting sensor 25i. Since the tape feeder 25 is provided with the power source 25j, it is possible to display the mounting position on the display unit 25d even when the tape feeder 25 is not mounted on the electronic component mounting machine 20 or the stand 49a.

Further, as shown in FIG. 9, the storage unit 45 is composed of the ID of the mounted electronic component reel 25 b, the remaining number of components, the name of the mounted component, and the component expiration time, using the ID of the tape feeder 25 as a key. Feeder part information database (feeder part information DB) is stored. Furthermore, as shown in FIG. 10, the storage unit 45 uses the ID of the tape feeder 25 as a key, the ID of the electronic component mounting machine 20 to be mounted, and the set position of the electronic component supply device 24 of the electronic component mounting machine 20 A feeder position information database (feeder position information DB) composed of the ID and the ID of the electronic component mounting line 10 to which the electronic component mounting machine 20 belongs is stored.

  The remaining component number management unit 46 determines the components of each tape feeder 25 of the electronic component mounting machine 20 from the quantity of components held by the tape feeder 25 before the start of mounting and the number of consumed components received from the electronic component mounting machine 20. Each of the remaining numbers is calculated. The component replenishment notice unit 47 is held by the tape feeder 25 from the number of remaining components of each tape feeder 25 stored in the storage unit 45 and the production time per board received from the electronic component mounting apparatus 20. This is to calculate the time when a certain part becomes empty (parts out time), that is, the remaining time for replenishing parts (or time to be replenished). The remaining time for replenishing this component is the remaining time until the set time when the tape feeder 25 should be set in the electronic component mounting machine 20. The set time refers to the time when the part is empty, that is, the time when the part should be replenished. The information fetching unit 48 is information on the state (operation status) of each electronic component mounting machine 20 (for example, the number of parts consumed, the number of parts used per board, the production time per board, the planned number of boards, The number of substrates produced).

  The interface unit 49 transmits / receives information to / from the tape feeder 25 via a stand 49a provided in the interface unit 49. The stand 49a is electrically connected to the connecting portion of the tape feeder 25. When the tape feeder 25 is connected to the stand 49a, the parts management computer 40 provides information on the position where the tape feeder 25 is to be mounted, information on the association between the reel and the tape feeder 25, and the like. Sent to.

  The component management computer 40 is preferably installed in the component preparation area Ab, but may be installed in another area. Further, the above-described component management function of the component management computer 40 may be installed in the electronic component mounter management computer 30 without providing the component management computer 40. In this case, the operator of the electronic component mounter management computer 30 also serves as the component management operator OP1.

  Next, the operation of the electronic component mounting system configured as described above will be described. The control units 20a, 31, and 41 of the electronic component mounter 20, the electronic component mounter management computer 30, and the component management computer 40 perform their own processes in parallel and exchange data as necessary. It is carried out.

  When the electronic component reel 25b is replaced, after the electronic component reel 25b is set in the tape feeder 25 by the component management operator OP1, the barcode labels Dfa and Ra attached to both are read by the barcode reader 43a. . The component management computer 40 associates the ID of the electronic component reel 25b indicated by the barcode label Ra, the name of the mounted component, and the number of mounted components with the ID of the tape feeder 25 indicated by the barcode label Dfa. Register as feeder parts information (association information). That is, when the parts management computer 40 receives feeder parts information from the parts management operator OP1, the parts management computer 40 additionally registers new feeder parts information in the feeder parts information DB shown in FIG.

  The component management computer 40 uses the tape feeder 25 before being mounted on the electronic component mounting machine 20 to prepare information for mounting on the electronic component mounting machine 20. At least the data is transmitted to the acquisition unit 25f of the tape feeder 25 that has been completed. The tape-type feeder 25 that is the tape-type feeder 25 before being mounted on the electronic component mounter 20 and is ready to be mounted on the electronic component mounter 20 includes the electronic component reel 25b mounted on the tape-type feeder 25, Both IDs are read into the component management computer 40, and the tape feeder 25 and the electronic component reel 25b are associated with each other.

  Further, the component management computer 40 manages all remaining component numbers of the tape feeder 25 set in the electronic component mounter 20 connected via the LAN 50. Specifically, the component management computer 40 identifies the ID of the tape feeder 25 in which the component is consumed as the component is mounted on the board from the electronic component mounter 20 (or the electronic component mounter management computer 30) and the ID. When the number of consumed parts is received, the feeder part information of the tape feeder 25 with the corresponding ID is read from the storage unit 45, the consumed number is subtracted from the remaining number of parts, and the subtraction result is used as the new remaining part number. Is updated and registered in the storage unit 45.

  Further, the parts management computer 40 reads all the IDs of the tape feeders 25 currently involved in production based on the feeder position information DB shown in FIG. 10, and stores the feeder part information of those tape feeders 25. The feeder part information DB is stored in the feeder part information DB, and the feeder part information including the calculation result is calculated in the feeder part information DB. Register for update. Thereby, the component management computer 40 manages all the component expiration times of the tape feeder 25 set in the electronic component mounter 20. Note that the part run-out time is calculated by the following formula 1.

  The number of components used per board is acquired from the electronic component mounter 20 or the electronic component mounter management computer 30.

  Further, the component management computer 40 displays the tape feeder 25 on the display unit 44 in the order of short component shortage time. Specifically, as shown in FIG. 11, the tape feeder 25 is displayed in the order of the shortest set time and the part-out time using the ID of the tape feeder 25 as a key. The feeder set position indicates a line ID, an electronic component mounter ID, and a set position ID in order from the left, and specifies a place where the tape feeder 25 is set. Thus, the tape feeder 25 that runs out of parts can be notified to the parts management operator OP1 together with the time of running out of parts.

  Further, the parts management computer 40 monitors the tape feeder 25 that runs out of parts during production, and warns the tape feeder 25. Specifically, the tape feeder 25 calculates the production completion time from the planned production quantity and production time, and when the production completion time is equal to or shorter than the part outage time calculated earlier, It is determined that parts are out of production, and a warning is displayed on the display unit 44 (see FIG. 11). As a result, even when the part run-out time is the same or long, the tape feeder 25 that needs to be preferentially supplied with the parts can be notified to the part management operator OP1. Further, when a part is replenished to the tape type feeder 25 for which the warning is issued, the production completion time becomes longer than the part out time. Therefore, it is determined that the part does not run out during the production, and the display unit 44 warning is released. The production completion time is calculated by the following formula 2.

(Equation 2)
Scheduled number of production x Production time

  The planned production number is acquired from the electronic component mounter 20 or the electronic component mounter management computer 30.

  The component management operator OP1 prepares in advance the tape feeder 25 that holds the electronic component reel 25b necessary for the electronic component mounting machine 20 based on the notice or warning of component failure by the component management computer 40 described above. The electronic component mounting machine 20 is delivered to the shelf Tas of the electronic component mounting line 10 before the components run out.

  When the electronic component reel 25b is transported, the display 25d of the tape feeder 25 displays the planned mounting position where the tape feeder 25 is to be mounted, so that the component management operator OP1 displays the display. Can be transported to the shelf Tas of the electronic component mounting line 10 to which the planned mounting position belongs. In addition, this conveyance may be performed not by the parts management operator OP1 but by other workers.

  Further, the information about the component out warning issued by the component management computer 40 is transmitted to the electronic component mounting machine 20, and the electronic component mounting machine 20 also issues a warning. As a result, the operator OP2 of the electronic component mounting machine 20 takes out the new tape feeder 25 instead of the tape feeder 25 that is out of components from the shelf Tas that has been delivered and stored in advance. The electronic component supply device 24 is mounted. At this time as well, since the planned mounting position where the tape feeder 25 is to be mounted is displayed, the component management operator OP1 observes the display, and the predetermined electronic component mounting machine 20 that is the predetermined mounting position is the predetermined mounting position. Can be mounted in the slot position.

  As is clear from the above description, in the present embodiment, the tape feeder 25 that is not yet mounted on the electronic component mounting machine 20 and is ready for mounting on the electronic component mounting machine 20. Displayed position information stored in the storage unit 25g is displayed on the display 25d. In other words, it is possible to display the expected mounting position on the tape feeder 25 itself. Thereby, in the stage before the tape type feeder 25 is mounted on the electronic component mounting machine 20, the operator can see the planned mounting position displayed on the display unit 25 d of the tape type feeder 25 being carried alone. However (while confirming), the electronic component mounting machine 20 can be reliably and smoothly mounted at the planned mounting position. As a result, erroneous mounting can be reliably suppressed.

  In addition, an electronic component reel 25b that is wound around a component tape in which components to be supplied to the electronic component mounting machine 20 are wound and is detachably mounted on the tape feeder 25, and the electronic component reel 25b are attached to the tape feeder 25. A mounting sensor 25i that detects whether the electronic component reel 25b is mounted, and an acquisition unit 25f that acquires association information between the electronic component reel 25b and the tape feeder 25; When the electronic component reel 25b is removed from the tape feeder 25, the mounting sensor 25i detects that the electronic component reel 25b has not been detected by detecting that the mounting sensor 25i has not been mounted, and then a new electronic component reel 25b is displayed. When attached to the tape feeder 25, the attachment sensor 25i detects the attachment, and then the acquisition unit 25f is a new electronic device. When the association information of the product reel 25b and the tape feeder 25 is acquired, the display indicating that the electronic component reel 25b displayed on the display unit 25d is not collated is canceled, and the association information of the tape feeder 25 is acquired. If not, the display indicating that the electronic component reel 25b displayed on the display 25d is not collated is continued. Thereby, the operator can confirm that the association (collation) between the newly attached electronic component reel 25b and the tape feeder 25 is updated only by looking at the display content of the display 25d. Therefore, it is possible to suppress erroneous attachment of the tape feeder 25 to the electronic component mounting machine 20. In addition, the tape feeder 25 on which the electronic component reel 25b is mounted can be determined by checking the display content of the display 25d to confirm whether or not the association (collation) between the electronic component reel 25b and the tape feeder 25 is performed. It is possible to accurately inform the operator whether or not it is possible to use it.

  Moreover, the electronic component mounting machine 20 which has the effect of embodiment mentioned above can be provided.

The component management computer 40 is scheduled to be mounted on which the tape-type feeder 25 is mounted. The position information is at least transmitted to the acquisition unit 25f of the tape feeder 25 that is the tape feeder 25 before being mounted on the electronic component mounter 20 and is ready to be mounted on the electronic component mounter 20.

  As a result, in the component preparation area Ab, the component management computer 40 uses the tape feeder 25 before being mounted on the electronic component mounter 20 as an electronic component information about the mounting position where the tape feeder 25 is mounted. At least the data is transmitted to the acquisition unit 25f of the tape feeder 25 ready to be mounted on the component mounter 20. Therefore, the tape feeder 25 can reliably acquire the planned mounting position. Further, even during the transportation of transporting the tape feeder 25 from the component preparation area Ab to the production area As, the mounting position is displayed on the tape feeder 25 itself, so the operator can mount the electronic component mounting machine to be mounted. The tape feeder 25 can be reliably transported to 20. Further, in the production area As, the operator is displayed on the display unit 25d of the tape feeder 25 being carried alone before the tape feeder 25 is mounted on the electronic component mounting machine 20. While viewing (checking) the planned mounting position, the electronic component mounting machine 20 can be securely and smoothly mounted at the planned mounting position. As a result, erroneous mounting can be reliably suppressed.
