Description

  The present invention relates to an electronic component supply system that supplies electronic components to a tape feeder that supplies electronic components to an electronic component mounting machine by using a splicing unit.

  Patent Literature 1 discloses an electronic component supply system in which a plurality of electronic component mounting machines are connected to each other to construct a production line for producing boards. The plurality of electronic component mounting machines include a tape feeder that supplies an electronic component to be mounted on a substrate. The tape feeder is loaded with a reel around which a carrier tape containing electronic components is wound at a predetermined pitch.

  Here, the worker of the electronic component supply system performs a work of replenishing the electronic components before the electronic components of each tape feeder run out and the production line stops. The operator performs, for example, a splicing operation between the end of the carrier tape that is likely to run out of parts and the start of the supply carrier tape. For example, an operator goes to get an automatic splicing unit (ASU) that automatically performs a splicing operation, carries the ASU to a tape feeder to be supplied, and then performs the splicing operation.

  In the electronic component supply system of Patent Literature 1, when parts are expected to run out in a plurality of tape feeders, the current position of the ASU among a plurality of electronic component mounting machines equipped with a tape feeder in which the parts are expected to run out The replenishment order is determined so that the shorter the distance from the vehicle, the earlier the splicing operation can be performed.

WO 2015/166538

  However, in the electronic component supply system described above, for example, the position of the electronic component mounting machine that has just performed the splicing operation is estimated as the current position of the ASU from the operation history of the splicing operation. Therefore, if the worker has already moved from the position where the splicing operation was performed immediately before, the electronic component supply system determines the next tape feeder to be refilled based on the position deviating from the actual current position. Will be done. In view of the above, a first object of the present invention is to appropriately detect the current position of a splicing unit and determine the order of replenishment to more reliably optimize the replenishment route.

  Further, in the electronic component supply system described above, for example, the management numbers set in the electronic component mounting machine and the tape feeder are rearranged in the determined order of replenishment, the display of the management device, and the portable information terminal owned by the worker. To notify the worker. Then, for example, the worker searches for a tape feeder or the like to be replenished while walking the production line with the ASU. However, a single production line may be provided with a plurality of similar devices such as electronic component mounting machines of the same model. In this case, it is difficult for the worker to grasp which electronic component mounting machine or tape feeder is the next supply target device only by looking at the notified management number on the screen. The operator needs to confirm the management number attached to the tape feeder or the like by visual inspection. As a result, there is a possibility that the efficiency of the replenishment operation is reduced, and the production efficiency is reduced due to the stoppage of the production line. Therefore, a second object of the present invention is to enable a worker to easily confirm the position of a tape feeder to be supplied.

  An object of the present invention is to provide an electronic component supply system that solves at least one of the first and second problems described above.

  The electronic component supply system according to claim 1, wherein a tape feeder loaded with a reel around which a carrier tape containing the electronic component is wound is mounted, and the electronic component supplied from the tape feeder is mounted on a substrate. An electronic component mounting machine, a detection device for detecting identification information of the reel or the tape feeder, and a splicing operation of the carrier tape and the supply carrier tape of the reel mounted on the electronic component mounting machine are performed. And a splicing unit having a splicing device for replenishing the electronic component, and, among the plurality of electronic component mounting machines, the position of the reel or the tape feeder where the identification information is detected by the detection device. A position specifying unit that specifies the current position of the unit, and the position specifying unit Based on the specified current position of the splicing unit specified more, a replenishment target determination unit that determines a replenishment target tape feeder for replenishing the electronic component by the splicing device, and the replenishment target determination unit determines the replenishment target determination unit. A supply target notifying unit that notifies information of a tape feeder to be supplied.

  According to the configuration of the first aspect of the invention, the position specifying unit sets the position of the reel or the tape feeder where the identification information is detected by the detecting device as the specific current position of the splicing unit. Therefore, the specific current position is a position where the worker has performed the operation of detecting the identification information by the splicing unit detection device, that is, a position where the splicing unit is more reliably present. Accordingly, the position specifying unit can specify the accurate current position of the splicing unit without separately providing a device (such as GPS) for acquiring position information of the splicing unit. Further, the replenishment target determining unit can determine the next replenishment target tape feeder based on the more appropriate current position of the splicing unit. In addition, the replenishment target notifying unit notifies the worker of the information of the replenishment target tape feeder determined by the replenishment target determination unit, so that the replenishment route of the worker can be more reliably optimized. Therefore, this electronic component supply system can solve the first problem.

The dust box 47 is for discarding pieces (waste tape) of the carrier tape 31 generated by the splicing operation.

  In addition, a columnar column 48 is provided on the base 44. The pillar portion 48 is fixed in a state of standing upright along a direction perpendicular to the plane of the base table 44. The main body 42 is attached to the upper part of the pillar 48. The main unit 42 includes a splicing device 50, a reel bucket 51, a barcode reader 52, a communication unit 54 (see FIG. 6), and a display device 55. Further, the main body section 42 includes a main body processing section 42C having a CPU and various memories as a processing section for controlling each of the above devices. In the following description, as shown in FIG. 4, the reel 32 accommodated in the reel bucket 51 will be referred to as a supply reel 56 in order to distinguish it from the reel 32 loaded in the tape feeder 30.

  The splicing device 50 is a device that automatically joins the end of the carrier tape 31 wound around the reel 32 loaded on the tape feeder 30 to the start end of the carrier tape 31 wound around the supply reel 56. The splicing device 50 has a substantially rectangular parallelepiped shape that is long in one direction. The reel bucket 51 is provided on one side (a back side in FIG. 4) of the side surface facing the splicing device 50 in the longitudinal direction and at a position close to the side surface. The reel bucket 51 can accommodate a plurality of supply reels 56. The worker newly obtains the supply reel 56 and stores it in the reel bucket 51 in, for example, a storage or a reel storage area of the production lines 2A and 2B.

  Further, the splicing device 50 is provided with a feed groove 50A (only the feed groove on the near side is shown in FIG. 4) on each of the side surfaces facing each other in the longitudinal direction. The feed groove 50 </ b> A is a groove for inserting two carrier tapes 31 to be spliced to the center of the splicing device 50. At the center of the splicing device 50, a joining device (not shown) for attaching a splicing tape to the two carrier tapes 31 fed along the feed groove 50A and joining them together is provided. When the two carrier tapes 31 are fed into each of the feed grooves 50A by the operator, the splicing device 50 cuts unnecessary portions of the two carrier tapes 31 with a cutting device (not shown), and butt the cut surfaces of each other. The two carrier tapes 31 are joined by a joining device. When the splicing operation is completed, the splicing device 50 opens the upper cover 50B to bring the spliced carrier tape 31 into a state where it can be taken out.

  The barcode reader 52 is, for example, a cordless handy type that performs wireless communication with the main processing unit 42C of the main unit 42. The worktable 42D of the main body 42 is provided with an engaging portion 42E for hooking the barcode reader 52. The worker removes the barcode reader 52 from the engaging portion 42E and holds the barcode reader 52 in his / her hand to read the barcode 38 of the reel 32 removed from the tape feeder 30 or the barcode 38 of the supply reel 56 removed from the reel bucket 51. I do. Accordingly, in the splicing operation, the main body processing unit 42C executes a so-called splicing verify that checks whether the carrier tape 31 (supply reel 56) accommodating the correct electronic component has been prepared.

  The main body processing unit 42C starts the splicing verification when the bar code reader 52 reads the bar code 38 of the old reel 32 that has run out of components, and transmits the information of the bar code 38 of the reel 32 to the communication unit 54 (see FIG. 6). ) To the host computer 3. The communication unit 54 can communicate with the host computer 3 via a wireless LAN through an access point provided in the communication network 7, for example.

  Next, when the barcode 38 of the supply reel 56 is read by the barcode reader 52, the main body processing unit 42C transmits the information of the barcode 38 of the supply reel 56 to the host computer 3. The management data D2 stored in the storage device 3A of the host computer 3 stores information on the barcode 38 and data on the component code. Based on the information of the barcode 38 received from the main body processing unit 42C (splicing unit 5), the host computer 3 determines whether or not the component codes of the electronic components for which the splicing work is to be performed match, for example.

  When the host computer 3 determines that the collation of the electronic component is good, the host computer 3 notifies the main processing unit 42C that the collation is good. When the main body processing unit 42C receives the information indicating that it is good, the splicing device 50 automatically starts the splicing operation. Further, when the component codes of the electronic components do not match, the host computer 3 notifies the main body processing unit 42C of a collation error. When the main body processing unit 42C receives the information indicating that there is a collation error from the host computer 3, it displays the fact on the display device 55, and stops the splicing operation. As described above, the splicing unit 5 (the main body processing unit 42C) can prevent splicing of an erroneous carrier tape 31 such as a different type of electronic component by a process linked with the host computer 3. ing.

  The display device 55 includes a touch panel 55A having a display function and an input function. FIG. 5 shows an example of a display screen when the touch panel 55A is viewed from the front. At the center of the touch panel 55A, there is provided an information display section 55B for displaying information such as the above-mentioned verification error and the number of the barcode 38 read by the barcode reader 52. In addition, on the upper right of the touch panel 55A, a radio field intensity display section 55C for displaying the intensity of the radio wave received by the communication section 54 from the access point is provided. A cancel button 55D is provided below the information display section 55B. The cancel button 55D is for notifying the main processing section 42C of a stop instruction, for example, when the processing is to be stopped during the above-described splicing verification.

  Further, on the left side of the information display section 55B, a notice display section 55E indicating a notice of the tape feeder 30 in which parts are expected to run out is provided. The touch panel 55A of the present embodiment is provided with five notice display sections 55E. The notice display section 55E displays information about the tape feeder 30 to be replenished, which is expected to be out of components received from the host computer 3. For example, the module number “2” for identifying the electronic component mounting machine 13, the slot number “4” of the slots S 1 to Sn of the tape feeder 30 to be refilled, and the part out of The expected time until occurrence "00:03:30" is displayed. In this case, the notice display section 55E indicates that the tape feeder 30 mounted on the slot number "4" of the module number "2" will be out of parts after 3 minutes and 30 seconds. The module numbers are set in the order of 1, 2, 3,... From the upstream to the downstream of the production line 2A for the plurality of electronic component mounting machines 13, for example. Further, the method of indicating the position of the tape feeder 30 to be supplied by the notice display unit 55E described above is merely an example. For example, the overall configuration of the production line 2A is schematically shown, and the tape feeder to be supplied is indicated on the schematic diagram. 30 positions may be displayed.

  The main body processing section 42C of the main body section 42 collects, for example, ten pieces of information of the tape feeders 30 from which parts are expected to be exhausted from the host computer 3 in a collective manner. The main body processing unit 42C periodically executes the acquisition process. The main body processing unit 42C displays, on the notice display unit 55E, five pieces of the acquired ten pieces of information having a short estimated time until the component exhaustion occurs. In addition, the main body processing unit 42C causes the notice display unit 55E to display the five items to be displayed from the top to the bottom of the screen in order from the one with the shorter estimated time. Therefore, as shown in FIG. 5, the estimated time displayed on the notice display section 55E increases in order from the top to the bottom of the screen. The main body processing unit 42C may, for example, open the upper cover 50B after the above-described splicing operation is completed, check the spliced tape by the operator, and, at the timing when the upper cover 50B is closed, display a notice indicating that the splicing operation is completed. It is preferable to delete 55E from the display of the touch panel 55A.

  The splicing unit 5 includes a GPS device 58 (see FIG. 6), and periodically transmits a current position (hereinafter, referred to as an “actual current position”) P1 to the host computer 3. Note that the “real current position P1” here is different from a specific current position P2 described later, and refers to a current position directly obtained by using a means for obtaining a position such as the GPS device 58.

(4. Notification process for supply target)
Next, a replenishment target notification process for notifying the splicing unit 5 of the tape feeder 30 to be replenished from the host computer 3 will be described. FIG. 6 shows a control flow in the replenishment target notification process and the approach notification process described later. For example, the host computer 3 notifies the splicing unit 5 of the supply target so as to perform supply (splicing work) for each of the production lines 2A and 2B. Note that the host computer 3 may manage the plurality of production lines 2A and 2B collectively and execute a supply target notification process to the splicing unit 5 so as to perform supply beyond the production line.

  As shown in FIG. 6, in addition to the storage device 3A and the communication unit 3B, the host computer 3 includes a position specifying unit 61, a supply target determination unit 62, a supply target notification unit 63, an actual position acquisition unit 64, a distance determination A section 65 and an approach notification section 66 are provided. The processing of the position specifying unit 61 and the like is realized by, for example, executing a program on a CPU of the host computer 3. Alternatively, the processing of the position specifying unit 61 and the like may be realized by hardware.

  First, when the barcode reader 52 reads the feeder ID 39 (barcode) of the tape feeder 30 and the barcode 38 of the reel 32 loaded in the tape feeder 30, the main body processing unit 42C of the splicing unit 5 reads the data. The information D3 of the feeder ID 39 and the barcode 38 is transmitted to the position specifying unit 61 of the host computer 3 via the communication unit 54.

  The position specifying unit 61 specifies the current position of the splicing unit 5 by comparing the information D3 such as the barcode 38 and the management data D2. As described above, in the management data D2, the tape feeder 30 (feeder ID 39) and the reel 32 (bar code 38) are arranged in which slot S1 to Sn of which electronic component mounting machine 13 of the production line 2A, 2B. Is set.

  For example, the management data D2 includes the module number of the electronic component mounting machine 13, the slot number of the electronic component mounting machine 13, the feeder ID 39 of the tape feeder 30 mounted in the slot, and the bar code 38 of the reel 32 mounted on the feeder ID 39. And data in which component codes of electronic components of the carrier tape 31 wound on the reel 32 are associated with each other. For this reason, the position specifying unit 61 searches the management data D2 for data corresponding to the barcode 38 or the like of the information D3 received from the splicing unit 5 (main body processing unit 42C), and reads the electronic component from which the barcode 38 is read. The position of the mounting machine 13, for example, the number (module number) from the upstream in the production lines 2 </ b> A and 2 </ b> B is acquired as the current position of the splicing unit 5. Alternatively, the position specifying unit 61 searches the management data D2, and acquires the slot number (the position of the tape feeder 30 or the reel 32) as the current position of the splicing unit 5 in addition to the module number.

  The position specifying unit 61 outputs the specified current position (hereinafter, referred to as “specific current position”) P2 to the supply target determining unit 62. The specific current position P2 is the current position of the splicing unit 5 specified by using a unit used for any purpose other than specifying the position of the feeder ID 39, the barcode 38, or the like. Based on the specific current position P2 of the splicing unit 5, the replenishment target determining unit 62 selects a replenishment target tape feeder 30 to be subjected to the next splicing operation from among the replenishment target tape feeders 30 in which parts are expected to run out. decide.

  Accordingly, the replenishment target determining unit 62 uses the barcode reader 52 to supply the replenishment target tape feeder 30 already displayed on the notice display unit 55E of the display device 55, that is, the replenishment target tape feeder that has already been notified from the host computer 3. At the timing when the identification information (feeder ID 39 and barcode 38) of the tape feeder 30 is read, a process of determining a new tape feeder 30 to be supplied is executed. Alternatively, the replenishment target determining unit 62 executes a process of determining the replenishment target tape feeder 30 in accordance with the timing at which the barcode reader 52 reads the identification information of the tape feeders 30 other than the replenishment target.

  As described above, when the bar code 38 of the supply target reel 32 which has already been notified, that is, the old reel 32 that has run out of components is read, splicing verification is automatically started. In this case, it is not necessary to newly replenish the tape feeder 30 during the splicing verification. Therefore, the replenishment target determining unit 62 excludes the tape feeder 30 under the verification from the newly determined replenishment target tape feeder 30. Is preferred. Alternatively, the splicing unit 5 does not automatically start the verification when the bar code 38 of the old reel 32 that has run out of parts is read, but displays the display for prompting the operator to start the verification or to notify the information D3. The operation may be performed on the display device 55 to receive an instruction from the operator.

  Next, the replenishment target determination unit 62 determines whether there are a plurality of replenishment target tape feeders 30 for which parts are expected to run out within a predetermined time (for example, 10 minutes). When there is only one tape feeder 30 to be replenished, the replenishment target determination unit 62 determines that the tape feeder 30 is a replenishment target tape feeder 30 when there is only one replenishment target tape feeder 30 that is expected to run out. The replenishment target determining unit 62 outputs replenishment information D4 (such as the module number and the numbers of the slots S1 to Sn) relating to the determined replenishment target tape feeder 30 to the replenishment target notifying unit 63. The supply target notifying unit 63 transmits the supply information D4 to the main processing unit 42C via the communication unit 3B. The main body processing unit 42C displays the received replenishment information D4 on the notice display unit 55E of the display device 55. Thereby, the operator of the splicing unit 5 can execute the splicing operation on the tape feeder 30 to be supplied according to the display on the display device 55.

  When there are a plurality of tape feeders 30 to be replenished that are expected to run out of parts, the replenishment target determining unit 62 determines the distance between the specific current position P2 input from the position specifying unit 61 and the tape feeder 30 to be replenished. The calculation is performed for each tape feeder 30 to be supplied. When calculating the distance from the splicing unit 5 to the tape feeder 30 to be supplied, the supply target determination unit 62 gives priority to the tape feeder 30 having a shorter distance to the splicing unit 5 among the plurality of tape feeders 30 to be supplied. Then, the priorities are determined so that the splicing operation is performed. The replenishment target determination unit 62 calculates the distance between the position of the electronic component mounting machine 13 on which the replenishment target tape feeder 30 is mounted and the specific current position P2 without using the position of the replenishment target tape feeder 30 as a reference. Alternatively, the priority of the supply target may be determined based on the position of the electronic component mounting machine 13.

  FIG. 7A illustrates an example of a production line 2A that performs a supply target notification process. As shown in FIG. 7A, the production line 2A includes six electronic component mounting machines 13A to 13F. Each of the electronic component mounting machines 13A to 13F has six tape feeders 30 mounted thereon. In the following description, the first, second,..., Sixth tape feeders 30 are described in order from the left side in FIG. 7A. An operator is assigned to the production line 2A.

  In the example shown in FIG. 7A, each of the sixth slot position SP1 of the electronic component mounting machine 13D, the third slot position SP2 of the electronic component mounting machine 13F, and the fifth slot position SP3 of the electronic component mounting machine 13C. It is assumed that the tape feeder 30 is expected to run out of parts. It is also assumed that the tape feeder 30 at each of the slot positions SP1, SP2, and SP3 has a longer expected component cutout time in this order. FIG. 7B is an example of the display screen of the touch panel 55A, which is consistent with the notation of FIG. 7A for easy understanding of the description. For example, when the sixth slot position SP1 of the electronic component mounting machine 13D is indicated, , The display of the notice display unit 55E is shown as "D-6 (SP1)". The notice display unit 55E shown in FIG. 7B displays “D-6 (SP1)”, “F-3 (SP2)”, and “C-5 (SP3)” in ascending order of the expected time of the above-mentioned part exhaustion. Is displayed.

  First, as shown in FIG. 7A, when starting a splicing operation, for example, the worker moves to the splicing unit 5 arranged on the production line 2A. The operator reads the barcode 38 of the reel 32A loaded on the third (A-3) tape feeder 30 of the electronic component mounting machine 13A installed near the splicing unit 5 by the barcode reader 52. The tape feeder 30 of “A-3” is a tape feeder 30 other than the splicing target whose parts are not expected to run out at the present time. Thereby, as shown in FIG. 7C, the position specifying unit 61 specifies, for example, the third slot position of the electronic component mounting machine 13A as the specific current position P2.

  The replenishment target determining unit 62 calculates the distance between the specific current position P2 and the replenishment target tape feeder 30 (slot positions SP1 to SP3). As shown in FIG. 8A, the distance L3 between the specific current position P2 and the slot position SP3 (C-5) of the electronic component mounting machine 13C is the shortest. The distance L2 between the specific current position P2 and the slot position SP2 (F-3) of the electronic component mounting machine 13F is the longest. The distance L1 between the specific current position P2 and the slot position SP1 (D-6) of the electronic component mounting machine 13D is a distance (L2> L1> L3) between the distance L3 and the distance L2. For this reason, the replenishment target determination unit 62 raises the priority of the electronic component mounting machine 13C (slot position SP3), the electronic component mounting machine 13D (slot position SP1), and The order of the splicing work is determined in the order of the component mounting machine 13F (slot position SP2).

  The replenishment target determining unit 62 outputs replenishment information D4 including information on the plurality of tape feeders 30 to be replenished (module numbers and the numbers of the slots S1 to Sn) and information on the determined priority to the replenishment target notification unit 63. I do. The supply target notifying unit 63 transmits the supply information D4 to the main processing unit 42C via the communication unit 3B. The main body processing unit 42C causes the notice display unit 55E of the display device 55 to display the received supply information D4 in accordance with the priority order of the received supply information D4. As shown in FIG. 8B, the notice display unit 55E is rearranged in order and displays “C-5 (SP3)”, “D-6 (SP1)”, and “F-3 (SP2)” in order from the top. Have been.

  Thus, the operator of the splicing unit 5 can take appropriate measures, for example, by executing the splicing operation from the tape feeder 30 with the highest priority according to the display on the display device 55. For example, as shown in FIG. 8C, the operator moves to the slot position SP3 of the electronic component mounting machine 13C having the highest priority while pressing the splicing unit 5 according to the display of the notice display section 55E.

  It is also assumed that the number of tape feeders 30 to be replenished newly increases during the movement. For example, assume that the tape feeder 30 at the fourth slot position SP4 (E-4) of the electronic component mounting machine 13E is expected to run out of components. As described above, the main processing unit 42 </ b> C periodically acquires information on the tape feeder 30 from which the component is expected to run out from the host computer 3. Therefore, as shown in FIG. 9A, the main body processing unit 42C adds the information of the newly added slot position SP4 to the notice display unit 55E.

  After moving to the slot position SP3, the operator starts a splicing operation on the tape feeder 30 at the slot position SP3 to be spliced. The operator reads the barcode 38 of the reel 32 loaded in the tape feeder 30 by the barcode reader 52 for splicing verification. Thereby, as shown in FIG. 9B, the position specifying unit 61 newly specifies the fifth slot position SP3 of the electronic component mounting machine 13C as the specified current position P2.

  The replenishment target determining unit 62 again determines the next replenishment target based on the specific current position P2 (slot position SP3) newly specified by the position specifying unit 61. As shown in FIG. 9B, distances L1, L2, and L4 between the specific current position P2 and each of the slot positions SP1, SP2, and SP4 have a relationship of L2> L4> L1. Accordingly, as shown in FIG. 9C, the notice display section 55E is rearranged in order, and “C-5 (SP3)”, “D-6 (SP1)”, and “E-4 (SP4)” in order from the top. , "F-3 (SP2)".

  Then, as shown in FIG. 9D, the main body processing unit 42C completes the splicing operation at the timing when the upper cover 50B is closed and the operator closes the upper cover 50B after confirming the spliced tape after opening the upper cover 50B. The display on the notice display section 55E (C-5 (SP3)) is deleted. If the splicing has failed, the work can be restarted by pressing the cancel button 55D. In this way, the main body processing unit 42C changes the display of the notice display unit 55E according to the reading of the barcode 38 and the like.

  The replenishment target determining unit 62 may execute a process of increasing the priority of the replenishment target tape feeder 30 in which the estimated time until the component runs out is equal to or less than a predetermined time. Here, the predetermined time is, for example, a moving time during which the worker moves from the specific current position P2 to the tape feeder 30 to be supplied, and a time when the splicing operation is performed on the tape feeder 30 to be supplied using the splicing unit 5. It is calculated by the sum of the required standard work time (for example, 30 seconds). Thus, it is possible to prevent the production line 2A from stopping due to a lack of parts by giving priority to replenishment before the parts run out, instead of giving priority only to the tape feeder 30 having a shorter distance. Become.

(5. Approach notification processing)
Next, an approach notification process for notifying an approach when the splicing unit 5 and the tape feeder 30 to be supplied approach each other will be described. As shown in FIG. 6, the real position acquisition unit 64 of the host computer 3 acquires the actual current position P1 from the GPS device 58 of the splicing unit 5 at predetermined time intervals, and acquires the current position of the splicing unit 5. The actual position acquisition unit 64 outputs the acquired actual current position P1 to the distance determination unit 65. The information (supply information D4) of the tape feeder 30 to be supplied determined by the supply target determining unit 62 is input to the distance determination unit 65.

  The distance determination unit 65 determines the actual current position P1 input from the actual position acquisition unit 64, that is, the position of the splicing unit 5, and the position of the supply target tape feeder 30 notified to the splicing unit 5 input from the supply target determination unit 62. Determine position and distance. In addition, the distance determination unit 65 can specify the position of the tape feeder 30 to be supplied from the information of the management data D2 in the same manner as the specification of the specific current position P2 by the position specification unit 61 described above.

  When the number of the tape feeders 30 to be supplied is one, the distance determination unit 65 determines whether the worker (the splicing unit 5) can reach a predetermined distance from the tape feeder 30 to be supplied based on the actual current position P1 acquired by the GPS device 58. ) Is determined to be approaching, and that fact is output to the approach notification unit 66. The approach notification unit 66 transmits to the main processing unit 42C that the tape feeder 30 to be supplied is approaching.

  When a plurality of supply target tape feeders 30 are present, the distance determination unit 65 makes a determination for each of the plurality of supply target tape feeders 30. Based on the actual current position P1, the distance determination unit 65 determines which of the tape feeders 30 the operator (splicing unit 5) has approached to a predetermined distance from any of the plurality of tape feeders 30 to be supplied. It outputs to the approach notification unit 66 whether the vehicle is approaching 30.

  FIG. 10 shows an example of the production line 2A that performs the approach notification processing. First, the operator moves the production line 2A while pushing and moving the splicing unit 5. At this time, the actual position acquisition unit 64 acquires the actual current position P1 from the GPS device 58 every predetermined time.

  In the example shown in FIG. 10, the fifth slot position SP1 (A-5) of the electronic component mounting machine 13A, the third slot position SP2 (D-3) of the electronic component mounting machine 13D, and the sixth slot position SP6 of the electronic component mounting machine 13F. It is assumed that the tape feeder 30 in the slot position SP3 (F-6) is expected to be out of parts. In this case, the distance determination unit 65 determines the position (slot position SP1 to SP3) of each tape feeder 30 to be supplied. The distance determination unit 65 determines, for example, whether or not the actual current position P1 moves within a range R1 of a distance L6 around each of the plurality of slot positions SP1 to SP3 indicated by broken lines in FIG.

  When the actual current position P1 moves within the range R1, the distance determination unit 65 notifies the main body processing unit 42C of which tape feeder 30 is approaching via the approach notification unit 66. For example, as shown in FIG. 11A, when the actual current position P1 moves within a range R1 around the slot position SP2, the distance determination unit 65 notifies the main processing unit 42C of the fact.

  Upon receiving the notification from the approach notification unit 66, the main processing unit 42C changes the display on the display device 55. For example, as shown in FIG. 11B, the main body processing unit 42C changes the color of the notice display unit 55E (D-3 (SP2) in this case) corresponding to the approaching tape feeder 30 so as to be prominent. I do. In the example illustrated in FIG. 11B, the parts other than the corresponding notice display unit 55E (D-3 (SP2)) are highlighted by hatching. Thus, the operator can recognize that the user has moved to the vicinity of the tape feeder 30 corresponding to the highlighted notice display unit 55E by seeing the change in the display. Note that the above-described method of notifying that the user has approached the tape feeder 30 to be supplied is an example. For example, the approach may be notified by sound from the electronic component mounting machine 13 to which the tape feeder 30 is mounted.

(6. Effect of Configuration of Embodiment)
In the electronic component supply system 1 of the above-described embodiment, the tape feeder 30 loaded with the reel 32 around which the carrier tape 31 containing the electronic component is wound is mounted, and the electronic component supplied from the tape feeder 30 is attached to the substrate Bd. A plurality of electronic component mounting machines 13 to be mounted, a bar code reader 52 (detection device) for detecting identification information (bar code 38 or feeder ID 39) of the reel 32 or the tape feeder 30, and a plurality of electronic component mounting machines 13. A splicing unit 5 having a splicing device 50 for performing a splicing operation between the carrier tape 31 of the reel 32 and the carrier tape 31 for replenishment and replenishing electronic components; Bar code 38 or feeder ID 39 was detected by code reader 52 Next, based on the position specifying unit 61 for specifying the position of the ruler 32 or the tape feeder 30 as the current position of the splicing unit 5 and the specific current position P2 of the splicing unit 5 specified by the position specifying unit 61, the splicing device 50 The replenishment target determining unit 62 that determines the replenishment target tape feeder 30 that replenishes the electronic components, and the replenishment target notification that notifies the replenishment information D4 (information) of the replenishment target tape feeder 30 determined by the replenishment target determination unit 62 A unit 63.

  According to this, the position specifying unit 61 sets the position of the reel 32 or the tape feeder 30 where the barcode 38 or the feeder ID 39 is detected by the barcode reader 52 as the specific current position P2 of the splicing unit 5. Therefore, the specific current position P2 is a position where the operator has performed an operation of detecting the barcode 38 or the like by the barcode reader 52 of the splicing unit 5, that is, a position where the splicing unit 5 is more reliably present. Accordingly, the position specifying unit 61 can specify the accurate current position of the splicing unit 5 without separately providing a device (such as a GPS) for acquiring position information of the splicing unit 5. In addition, the supply target determination unit 62 can determine the next tape feeder 30 to be supplied based on the more appropriate current position of the splicing unit 5. Further, the supply target notifying unit 63 notifies the worker of the supply information D4 of the tape feeder 30 to be supplied determined by the supply target determination unit 62, thereby more reliably optimizing the supply route of the worker. be able to.

  Further, the electronic component supply system 1 obtains the actual current position P <b> 1 of the splicing unit 5, and supplies the replenishment target based on the actual current position P <b> 1 of the splicing unit 5 acquired by the actual position acquiring unit 64. A distance determining unit 65 that determines a distance between the tape feeder 30 and the splicing unit 5; and a response that the distance determining unit 65 determines that the splicing unit 5 has approached a predetermined distance L6 from the tape feeder 30 to be supplied. And an approach notification unit 66 for notifying the user.

  According to this, the distance determination unit 65 determines the distance between the tape feeder 30 to be supplied and the splicing unit 5 based on the actual current position P1 where the splicing unit 5 actually acquired by the actual position acquisition unit 64 exists. Is determined. The approach notification unit 66 notifies the worker of the fact that the splicing unit 5 has approached the predetermined distance L6 from the tape feeder 30 to be supplied. Thereby, the worker can recognize that the tape feeder 30 to be supplied exists near the position where the worker is present by receiving the notification from the approach notification unit 66 while moving the splicing unit 5. As a result, the replenishment operation can be performed quickly, and the efficiency of the replenishment operation can be increased, and the production efficiency can be improved by maintaining the operation of the production lines 2A and 2B. Furthermore, the electronic component supply system 1 of the present embodiment includes both the position specifying unit 61 and the actual position acquiring unit 64, and thus, for example, the processing unit of both the position identifying unit 61 and the actual position acquiring unit 64 If the obtained specific current position P2 is compared with the actual current position P1, the current position of the splicing unit 5 can be determined more appropriately. Further, in the electronic component supply system 1, for example, even if one of the position specifying unit 61 and the actual position obtaining unit 64 does not operate due to some kind of malfunction, a malfunction occurs using the current position of the other processing unit. Processing can be continued.

  Further, the replenishment target determination unit 62 determines the replenishment target tape feeder 30 in accordance with the timing at which the barcode reader 52 detects the barcode 38 and the feeder ID 39 relating to the tape feeders 30 other than the replenishment target tape feeder 30. .

  Here, the workers of the production lines 2A and 2B perform various operations other than the splicing operation, such as replenishing the solder of the solder printing device 11, replacing the suction nozzle of the electronic component mounting machine 13, and coping with an error. I do. For this reason, the worker does not always have the splicing unit 5, and when not using the splicing unit 5, arranges the splicing unit 5 in a predetermined storage place of the production lines 2A and 2B or a place where the splicing unit 5 was used last time. May be kept. In this case, when the next splicing operation occurs, it is preferable that the position where the splicing unit 5 is arranged or the like is set as the current position and the next tape feeder 30 to be supplied is determined. On the other hand, when the barcode reader 52 detects the feeder ID 39 of the tape feeder 30 (or the reel 32) other than the tape feeder 30 to be replenished by the barcode reader 52, the replenishment target determining unit 62 of the present embodiment, The feeder 30 is determined. For example, the worker goes to pick up the splicing unit 5 and causes the barcode reader 52 to detect the feeder ID 39 of the tape feeder 30 installed at a location closest to that location. Thus, no matter where the splicing unit 5 is located on the production lines 2A and 2B, the replenishment target determining unit 62 determines the specific current position P2 of the splicing unit 5 at the timing when the barcode reader 52 detects the feeder ID 39 or the like. , The tape feeder 30 to be supplied can be appropriately determined.

  Further, the replenishment target determining unit 62 determines the identification information (feeder ID 39 and barcode 38) concerning the replenishment target tape feeder 30 notified by the replenishment target notification unit 63 in accordance with the timing at which the barcode reader 52 detects the following information. The tape feeder 30 to be supplied is determined.

  According to this, the replenishment target determination unit 62 switches the next replenishment target tape feeder 30 to the timing at which the splicing operation is started on the replenishment target tape feeder 30 once notified by the replenishment target notification unit 63. It is determined based on the specific current position P2. Therefore, in the electronic component supply system 1 of the present embodiment, it is possible to determine the next supply target tape feeder 30 based on the specific current position P2 (the position where the splicing operation is being performed) in which the splicing unit 5 exists more reliably. it can.

The splicing unit 5 may be configured to notify the completion of the splicing operation to the replenishment target determining unit 62 of the host computer 3. For example, the splicing apparatus 50 opens the upper cover 50B after the completion of the splicing operation, confirms the spliced tape by the operator, and, at the timing when the upper cover 50B is closed, notifies the main processing section 42C of the main body section 42 of the completion. Notify. Further, upon receiving the notification from the splicing device 50, the main body processing unit 42C transmits to the replenishment target determining unit 62 of the host computer 3 that the splicing operation has been completed. The replenishment target determining unit 62 may determine the next replenishment target tape feeder 30 in accordance with the timing at which the completion notification of the splicing work is received.
In this manner, the supply target determining unit 62 may determine the next supply target tape feeder 30 in accordance with the timing at which the splicing unit 5 completes the splicing operation to the supply target tape feeder 30.

  According to this, it is possible to determine the next supply target tape feeder 30 based on the specific current position P2 where the splicing unit 5 exists more reliably. Here, for example, when a plurality of workers are present in one production line 2A and each of the plurality of workers is performing a splicing operation by the splicing unit 5, each of the workers is required to supply the tape feeder 30 to be resupplied next. May change every moment according to the progress of the splicing work of each worker. On the other hand, in the electronic component supply system 1, the operator determines the next supply target tape feeder 30 in a state where the operator has completed the splicing operation and can move to the next supply target tape feeder 30. For this reason, the operator can be notified of the tape feeder 30 to be supplied more optimally.

  Further, the identification information is a barcode (barcode 38, feeder ID 39) for identifying the reel 32 or the tape feeder 30. The detection device is a barcode reader 52 that reads the barcode 38 and the like. The electronic component supply system 1 further includes a host computer 3 having management data D2 for managing the reel 32 mounted on the plurality of electronic component mounting machines 13 or the barcode 38 of the tape feeder 30 and the like. The position identification unit 61 identifies the specific current position P2 of the splicing unit 5 by comparing the information of the barcode reader 52 read by the barcode reader 52 with the management data D2.

  According to this, the worker reads the barcode (barcode 38, feeder ID 39) of any reel 32 or tape feeder 30 using the barcode reader 52. The host computer 3 manages information such as the bar code 38 of the reel 32 or the tape feeder 30 mounted on the plurality of electronic component mounting machines 13 with management data D2. The position identification unit 61 can identify information of the barcode reader 52 read by the barcode reader 52 in a splicing operation or the like against the management data D2 to identify a more appropriate current position of the splicing unit 5. .

  Further, the electronic component supply system 1 further includes a splicing unit 5 having a splicing device 50 and a display device 55. The display device 55 changes the display according to the notification from the approach notification unit 66.

  According to this, when moving the production lines 2A, 2B while possessing the splicing unit 5, the operator can easily change the display of the display device 55 to easily position the tape feeder 30 to be supplied. Can be grasped.
