Hereinafter, the splicing unit 5 according to the first embodiment embodying the splicing unit of the present invention will be described with reference to the drawings.

(1. Structure of electronic component supply System 1)

First, an electronic component supply system 1 including the splicing unit 5 according to the first embodiment will be described with reference to fig. 1. As shown in fig. 1, an electronic component supply system 1 is a system for mounting components on a substrate by sequentially performing a transfer of the substrate and a plurality of operations, i.e., solder printing, component mounting, reflow soldering, and the like. The electronic component supply system 1 includes a plurality of production lines (only 2 production lines 2A and 2B are shown in fig. 1), a host computer 3, a storage-site-side device 4, a splicing unit 5, and the like. Since the lines 2A and 2B have the same configuration, the line 2A will be mainly described in the following description, and the description of the line 2B will be appropriately omitted. The electronic component supply system 1 may be configured to include only 1 production line 2A.

The production line 2A of the present embodiment is configured by connecting and arranging the solder printing apparatus 11, the plurality of electronic component mounting machines 13, the mounting inspection apparatus 14, the reflow apparatus 15, and the like in this order from the upstream side to the downstream side. The devices 11 to 15 and the like constituting the production line 2A are connected to each other via the communication network 6 so as to be collectively controlled by the host computer 3.

A substrate loading device 111 for loading a substrate to be mounted into the solder printing apparatus 11 is attached to the upstream side of the solder printing apparatus 11. The solder printing device 11 is configured to be able to print solder for component bonding on the substrate supplied through the substrate loading device 111.

The plurality of electronic component mounters 13 are configured to be able to mount electronic components on the substrate on which the solder printing is performed by the solder printing apparatus 11. In the production line 2A of the present embodiment, a plurality of electronic component mounting machines 13 are provided, but 1 electronic component mounting machine 13 may be provided.

The mounting inspection device 14 is configured to inspect a substrate on which electronic components are mounted by the electronic component mounting apparatus 13, and to be able to determine a defective substrate. The reflow apparatus 15 is configured to heat the substrate determined to be well mounted by the mounting inspection apparatus 14 at a predetermined temperature and melt and solidify the solder paste printed on the substrate, thereby enabling solder bonding of the electronic component to the substrate.

The host computer 3 is provided for each of the production lines 2A and 2B, for example, and performs centralized management of the production lines 2A and 2B. The host computer 3 is mainly composed of a CPU, various memories, and a control circuit, and includes a storage device 3A. The storage device 3A is constituted by an optical drive device such as a hard disk drive, a flash memory, or the like. The storage device 3A stores management data D2 (see fig. 7) in addition to, for example, a control program for controlling each of the devices 11 to 15, job data D1 (see fig. 7) for producing substrates as planned, and the like. The host computer 3 is configured to read and execute a control program from the storage device 3A, and thereby can perform centralized control of the devices 11 to 15 and the like constituting the production lines 2A and 2B to be managed.

The job data D1 is data in which, for example, a wiring pattern printed on a substrate by the solder printing apparatus 11, the position and order of electronic components mounted on the substrate by the electronic component mounter 13, a production plan for producing several substrates, and the like are set. The host computer 3 transmits the job data D1 to the solder printing apparatus 11 and the electronic component mounter 13 via the communication network 6. The solder printing apparatus 11 prints a wiring pattern in accordance with the job data D1. The electronic component mounter 13 mounts electronic components on the board in accordance with the job data D1. The electronic component mounter 13 acquires component information such as a component code of an electronic component that can be supplied from the mounted tape feeder 30, a maximum number of electronic components that can be supplied, and the number of supplied (used) electronic components, together with identification information (a feeder ID39 and a barcode 38 shown in fig. 3) of the tape feeder 30 and the tape reel 32, and transmits the component information to the host computer 3. The host computer 3 associates the component information received from the electronic component mounting apparatus 13 with the feeder ID39 and the like, stores (manages) the component information for each tape feeder 30 and each tape reel 32, and can calculate the timing of occurrence of component depletion in each tape feeder 30.

The management data D2 is, for example, data indicating which slot S1 to Sn (see fig. 2) of which electronic component mounting machine 13 in the production line 2A, 2B the tape feeder 30 (see fig. 3) and the reel 32 are arranged. The host computer 3 of each of the production lines 2A and 2B stores, in the storage device 3A, the feeder ID39 (see fig. 3) of the tape feeder 30 mounted to each of the electronic component mounters 13, the barcode 38 of the tape reel 32 loaded on the tape feeder 30, and the component code of the electronic component of the carrier tape 31 wound on the tape reel 32 in association with each other as management data D2. The "component code" referred to herein means, for example, a model number of a component set by a manufacturer or the like.

The host computer 3 is connected to the communication network 7 via a communication unit 3B (see fig. 7). The host computer 3 communicates with other host computers 3, the storage-site-side device 4, and the splicing unit 5 via the communication network 7.

The storage-site-side device 4 is provided in a storage (not shown) for storing the tape feeder 30 and the tape reel 32 for replenishment. The storage-site-side device 4 is, for example, a personal computer, and mainly includes a CPU, various memories, and a control circuit. The storage-side apparatus 4, for example, applies a barcode 38 (see fig. 3) associated with a component code of an electronic component to the reel 32 newly delivered from the storage, and prints a seal showing the barcode 38 by a printer (not shown). The operator of the storage attaches the seal of the printed barcode 38 to the tape reel 32. The storage location side apparatus 4 adds a component code to the printed seal in addition to the information of the barcode 38.

The storage location-side device 4 includes a barcode reader 4A that detects the barcode 38. For example, the storage operator takes out the supply reel 32 from the storage to the reel storage of the production lines 2A and 2B. Alternatively, the worker of the splicing unit 5 takes out the supply reel 32 from the storage into the reel bucket 51 (see fig. 4). At this time, the worker reads the bar code 38 of the reel 32 taken out by the bar code reader 4A. The storage site-side device 4 is connected to the host computer 3 via the communication network 7. The host computer 3 can manage information on the reel 32 taken out from the storage on the basis of the data received from the storage site-side device 4.

(2. Structure of electronic component mounting machine 13)

Next, the structure of the electronic component mounting machine 13 will be described. As shown in fig. 2, the electronic component mounting apparatus 13 includes a substrate conveying device 21, a component supplying device 22, and a component transfer device 23. In the following description, the horizontal width direction (the left-right direction in fig. 2) of the electronic component mounting apparatus 13 is defined as the X-axis direction, the horizontal depth direction (the up-down direction in fig. 2) of the electronic component mounting apparatus 13 is defined as the Y-axis direction, and the direction perpendicular to the X-axis direction and the Y-axis direction is defined as the Z-axis direction.

The substrate conveyance device 21 is configured by a tape feeder or the like, and sequentially conveys the substrates Bd in a conveyance direction (X-axis direction in the present embodiment). The substrate conveyance device 21 positions the substrate Bd at a predetermined position in the electronic component mounting machine 13. The substrate conveyance device 21 then sends the substrate Bd out of the electronic component mounting apparatus 13 after the mounting process by the electronic component mounting apparatus 13 is performed.

The component supply device 22 supplies the electronic components mounted on the substrate Bd to the supply position Ps. The component supplying device 22 includes a plurality of grooves S1 to Sn arranged in parallel in the X-axis direction. Tape feeders 30 that can be attached and detached are attached to the plurality of grooves S1 to Sn, respectively. Further, a groove number for identifying each of the grooves S1 to Sn is set. The component supply device 22 feeds and moves the carrier tape 31 (see fig. 3) by the tape feeder 30, and supplies electronic components to a supply position Ps located on the front end side (upper side in fig. 2, left side in fig. 3) of the tape feeder 30.

The component transfer device 23 includes a head driving device 23A, a moving stage 23B, and an mounting head 23C. The head driving device 23A is configured to be able to move the moving stage 23B in the XY axis direction by a linear motion mechanism. The mounting head 23C is fixed to the moving stage 23B. Therefore, the mounting head 23C is configured to be movable in the X-axis direction and the Y-axis direction together with the movement of the moving table 23B.

The mounting head 23C is provided with a plurality of nozzles, not shown, which are detachable. The mounting head 23C supports each suction nozzle rotatably about an axis parallel to the Z axis and elevatable. Each suction nozzle is controlled in the elevation position, angle, and negative pressure supply state with respect to the mounting head 23C. Each nozzle sucks and holds the electronic component supplied to the supply position Ps of the tape feeder 30 by being supplied with the negative pressure.

(2-1. Structure of tape feeder 30)

As shown in fig. 3, the tape feeder 30 is loaded with a tape reel 32 on which a carrier tape 31 is wound. The carrier tape 31 accommodates electronic components at a predetermined pitch. The tape reel 32 is held by a feeder main body 34 of the tape feeder 30 and is attached to the tape feeder 30 so as to be detachable.

The tape feeder 30 incorporates a constant-feed mechanism 33. The constant-feed mechanism 33 includes: a tape guide gear 35 rotatably supported by the feeder main body 34 and engaged with a feed hole (not shown) of the carrier tape 31; and a motor (not shown) for rotating the guide belt gear 35 by 1 pitch. The rail 37 of the tape feeder 30 supports the carrier tape 31 fed from the tape reel 32 from below to form a conveyance path. The tape guide gear 35 is disposed below the rail 37, and a part thereof protrudes from a window formed in the rail 37 toward the upper surface side of the rail 37, and the protruding part can be engaged with a feed hole of the carrier tape 31. The tape guide gear 35 is driven to draw the carrier tape 31 on the rail 37 into the supply position Ps.

The constant-feed mechanism 33 feeds out a constant amount of the carrier tape 31 wound around the tape reel 32 through the tape guide gear 35, and supplies the electronic components one by one to a supply position Ps provided at the tip of the tape feeder 30. The tape feeder 30 supplies electronic components at the supply position Ps so as to be removable.

In addition, the barcode 38 is identification information for identifying the reel 32. As described above, the barcode 38 is given when, for example, the storage-site-side device 4 (see fig. 1) performs a process of registering the component code of the electronic component in association with the reel 32. The feeder ID39 is identification information for identifying the tape feeder 30, and is, for example, a barcode. The identification information for identifying the reel 32 and the tape feeder 30 is not limited to a bar code, and may be, for example, a two-dimensional code. Further, the tape reel 32 and the tape feeder 30 can be identified by using a wireless tag such as RFID.

(3. Structure of splicing Unit 5)

Fig. 4 shows a perspective view of the entire splicing unit 5. As shown in fig. 4, the splicing unit 5 includes a carriage portion 41 and a main body portion 42. The carriage unit 41 is configured by attaching a base 44 to 4 casters 43 (only 3 are shown in fig. 4). The operator can move the splicing unit 5 in a state where the splicing device 50 and the like are mounted, for example, by pressing a handle 42A provided on the main body portion 42. The base 44 is provided with a power supply unit 45, a reel holder 46, and a dust box 47.

The power supply device 45 includes a battery, and supplies electric power to the splicing device 50 and the display device 55 by turning on the power switch 42B of the main body portion 42. The reel holder 46 is a storage box for storing the reel 32 with used components removed from the tape feeder 30 at the time of the splicing operation. The dust box 47 is used to discard fragments (waste tape) of the carrier tape 31 and the like generated in association with the splicing operation.

The base 44 is provided with a columnar portion 48. The column portion 48 is fixed in a state of being erected in a direction perpendicular to the plane of the base 44. The body 42 is attached to an upper portion of the column 48. The main body 42 includes a splicing device 50, a reel bucket 51, a barcode reader 52, a communication unit 54 (see fig. 7), and a display device 55. The main body 42 includes a main body processing unit 42C (display processing unit) as a processing unit for controlling the above devices, and the main body processing unit 42C (display processing unit) includes a CPU and various memories. In the following description, as shown in fig. 4, the reel 32 housed in the reel bucket 51 is referred to as a supply reel 56 in order to distinguish the reel 32 loaded in the tape feeder 30.

The splicing device 50 is a device that automatically connects the end of the carrier tape 31 wound on the reel 32 loaded on the tape feeder 30 and the start of the carrier tape 31 wound on the supply reel 56. The splicing device 50 has a substantially rectangular parallelepiped shape with a long direction.

The reel bucket 51 is provided on one side (the back side in fig. 4) of the side surfaces of the splicing device 50 facing each other in the longitudinal direction and is located close to the side surface. The reel bucket 51 is provided with accommodating portions 51A for individually accommodating the plurality of supply reels 56. The worker newly obtains the supply reel 56 in, for example, a storage warehouse or a reel yard of the production lines 2A and 2B, and stores the supply reel in each storage portion 51A.

Fig. 5 is a perspective view of the reel bucket 51 as viewed from the front side (from the back side in fig. 4). In the following description, as shown in fig. 5, the reel bucket 51 will be described using respective directions (front-back, left-right, and up-down) as viewed from the front. In this case, the rear surface of the rear side of the reel bucket 51 is a surface facing the side surface of the splicing device 50 shown in fig. 4.

As shown in fig. 5, the reel bucket 51 of the present embodiment includes a box portion 61 and a plurality of partition plates 62 that partition the inside of the box portion 61. The box portion 61 has a bottomed box shape with an upper opening. The partition plates 62 are provided in the tank section 61, and a plurality of (9 in the present embodiment) partition plates are arranged in parallel at equal intervals in the left-right direction so that their planes face each other. Therefore, 10 housing units 51A partitioned by the partition plate 62 are provided in the box unit 61. The upper portions of the tank 61 and the partition plate 62 are formed in a shape inclined at a predetermined angle toward the upper side from the front side toward the rear side. Therefore, the supply reel 56 accommodated in each accommodating portion 51A is accommodated in a state in which a part thereof is exposed, at a position above the upper ends of the box portion 61 and the partition plate 62. This allows the worker to easily take out the supply reel 56 from the storage portion 51A.

Further, the 10 accommodating portions 51A are provided with accommodating position numbers 63 for identifying each other, and are marked on the front surface of the reel bucket 51 (the box portion 61). In the present embodiment, as an example, the housing position number 63 is set with numbers of 1, 2, and 3 · 10 in order from the right side to the left side with respect to the 10 housing portions 51A.

As shown in fig. 4, the splicing device 50 includes feed grooves 50A on the side surfaces opposite to each other in the longitudinal direction (only the feed groove on the front side is shown in fig. 4). The feed slot 50A is a slot for inserting the spliced 2 carrier tapes 31 into the central portion of the splicing device 50. A splicing device, not shown, that attaches a splicing tape to 2 carrier tapes 31 fed along the feed slot 50A and splices them is provided at the center of the splicing device 50. When the operator feeds 2 carrier tapes 31 into the feed slot 50A, the splicing device 50 cuts unnecessary portions of the 2 carrier tapes 31 by a cutting device (not shown), and joins the carrier tapes 31 by joining devices by butting the cut surfaces against each other. When the splicing operation is completed, the splicing device 50 opens the upper cover 50B, and the carrier tape 31 that has been spliced is taken out.

The barcode reader 52 is, for example, a code-less portable type structure that wirelessly communicates with the main body processing unit 42C of the main body unit 42. An engaging portion 42E for engaging with the barcode reader 52 is provided on the table 42D of the main body 42. The worker removes the barcode reader 52 from the engaging portion 42E and reads the barcode 38 of the reel 32 removed from the hand-held tape feeder 30 and the barcode 38 of the replenishment reel 56 taken out from the reel bucket 51. Thus, the main body processing unit 42C performs so-called splice verification for verifying whether or not the carrier tape 31 (supply reel 56) containing the correct electronic component is prepared during the splicing operation.

The main body processing unit 42C starts the splicing verification when, for example, the barcode 38 of the used reel 32 having used up components is read by the barcode reader 52, and transmits information of the barcode 38 of the reel 32 to the host computer 3 via the communication unit 54 (see fig. 7). the communication unit 54 can communicate with the host computer 3 by, for example, AN access point provided in the communication network 7 using wireless L AN.

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

When the host computer 3 determines that the electronic component verification is good, it notifies the main body processing unit 42C of the good. When the main body processing unit 42C receives the content of the good, the splicing operation is automatically started by the splicing device 50. When the component codes of the electronic components do not match, the host computer 3 notifies the main body processing unit 42C of a verification error. When receiving the content of the verification error from the host computer 3, the main body processing unit 42C displays the content on the display device 55 and stops the splicing operation. In this way, the splicing unit 5 (main body processing unit 42C) can prevent erroneous carrier tapes 31 having different types of electronic components or the like from being spliced by processing in cooperation with the host computer 3.

The display device 55 includes a touch panel 55A having a display function and an input function. Fig. 6 shows an example of a display screen of the touch panel 55A as viewed from the front. An information display unit 55B that displays information such as the above-described collation error is provided in the center of the touch panel 55A. A barcode display unit 55C that displays the number of the barcode 38 read by the barcode reader 52 is provided below the information display unit 55B.

A radio wave intensity display unit 55D that displays the intensity of the received radio wave received by the communication unit 54 from the access point is provided on the right side of the touch panel 55A. A reel arrangement button 55E for setting the supply reel 56 stored in the storage portion 51A of the reel bucket 51 is provided on the left side of the radio wave intensity display portion 55D and on the information display portion 55B. The details of the operation of the reel arrangement button 55E will be described later. A cancel button 55F is provided below the information display unit 55B. The cancel button 55F is a button for notifying the main body processing unit 42C of a cancel instruction when the process is to be stopped in the above-described splice check.

On the left side of the information display portion 55B, a notice display portion 55G is provided which shows a notice of the tape feeder 30 that the component is expected to run out. The touch panel 55A of the present embodiment is provided with 5 advance notice display units 55G. The advance notice display unit 55G displays information of the tape feeder 30 that is expected to be supplied with the component end received from the host computer 3. For example, the top advance notice display section 55G displays the module number "2" for identifying the electronic component mounter 13, the slot numbers "4" for the slots S1 to Sn of the tape feeder 30 to be replenished, and the expected time "00" before the occurrence of component end-up: 03: 30". In this case, the notice display section 55G displays that component depletion has occurred after 3 minutes and 30 seconds in the tape feeder 30 mounted in the slot number "4" of the module number "2". The module numbers are set in the order of 1, 2, and 3 · for example from the upstream to the downstream of the production line 2A with respect to the plurality of electronic component mounting machines 13. The method of indicating the position of the tape feeder 30 to be supplied by the forenotice display unit 55G is an example, and the entire configuration of the production line 2A may be indicated by a schematic diagram, for example, and the position of the tape feeder 30 to be supplied may be indicated on the schematic diagram.

The main body processing unit 42C of the main body 42 acquires 10 pieces of information of the tape feeders 30, for example, which are expected to run out of components, from the host computer 3. The main body processing unit 42C periodically executes the acquired processing. The main body processing unit 42C displays 5 pieces of information, which is predicted to be short before the occurrence of the component depletion, among the acquired 10 pieces of information, on the advance notice display unit 55G. Then, the main body processing unit 42C displays 5 pieces of information displayed on the advance notice display unit 55G from the upper side toward the lower side of the screen from the information shorter in expected time. Therefore, as shown in fig. 6, the estimated time displayed on the advance notice display unit 55G increases in chronological order from the upper side toward the lower side of the screen. It is preferable that the main body processing unit 42C erases the notice display unit 55G indicating completion of the splicing operation from the display on the touch panel 55A at a timing when the upper cover 50B is opened after the completion of the splicing operation and the upper cover 50B is closed after the worker confirms the spliced tapes, for example.

(4. display processing of the mosaic Unit 5)

Next, a display process of the display device 55 (touch panel 55A) of the mosaic unit 5 (main body processing unit 42C) will be described. Fig. 7 shows a control flow of the display processing. As shown in fig. 7, the main body processing unit 42C of the main body unit 42 includes an acquisition processing unit 71, a determination processing unit 72, a list display unit 73, an assignment processing unit 74, and a correlation creation processing unit 75. The processing of the list display unit 73 and the like is realized by executing a program on a CPU included in the main body processing unit 42C. Alternatively, the processing of the list display section 73 and the like may be realized by hardware.

The main body 42 (see fig. 4) includes a storage device 77 for storing the associated data D3. The creation-related data D3 stores data in which the storage position number 63 of the reel bucket 51 and the component code of the supply reel 56 stored in the storage portion 51A of the storage position number 63 are related to each other. The splicing unit 5 executes display processing corresponding to an operation from the operator based on the building related data D3. The method of generating the related data D3 will be described later.

First, as described above, the main body processing unit 42C acquires the information of the component end from the main computer 3. The acquisition processing unit 71 of the main body processing unit 42C periodically acquires, for example, 10 pieces of component end information D4 of the tape feeder 30 from the host computer 3, which is expected to cause component end. The management data D2 includes data indicating which slot S1 to Sn of which electronic component mounting machine 13 in the production line 2A or 2B the tape feeder 30 (feeder ID39) or the reel 32 (barcode 38) is disposed in. For example, the management data D2 stores data in which a module number of the electronic component mounter 13, a slot number of the electronic component mounter 13, a feeder ID39 of the tape feeder 30 mounted in the slot, a barcode 38 of the tape reel 32 loaded on the feeder ID39, and a component code of an electronic component of the carrier tape 31 wound on the tape reel 32 are associated with each other.

The acquisition processing unit 71 acquires various data of the management data D2 described above as the element end information D4. The acquisition processing unit 71 stores the acquired component end information D4 in the storage device 77. Based on the component end information D4, the acquisition processing unit 71 displays the module number and slot number of the tape feeder 30 for which component end is expected and the expected time of component end on the notice display unit 55G of the display device 55. The acquisition processing unit 71 acquires, as the component end information D4, a component code to be supplied to the tape feeder 30 where component end is expected. The "component end information D4 including a component code to be replenished" corresponds to the "information for specifying the replenishing reel 56" in the present application. The information (identification information) for identifying the supply reel 56 is not limited to the component code, and may be, for example, the barcode 38 of the supply reel 56 in which the tape feeder 30 expected to run out of components matches the component code.

The determination processing unit 72 inputs the component-end information D4 acquired from the acquisition processing unit 71, in response to the acquisition processing unit 71 newly acquiring the component-end information D4 from the host computer 3. The determination processing unit 72 determines whether or not the reel bucket 51 contains the supply reel 56 having the component code that matches or corresponds to the component code of the input component end information D4, based on the set-up correlation data D3. For example, when the determined component code is of a plurality of types, the determination processing unit 72 displays that the supply reel 56 corresponding to at least one type of component code is not accommodated in the reel bucket 51. Note that the determination processing unit 72 may display the non-storage only when the predetermined number and ratio are not stored.

When the determination processing unit 72 determines that the replenishment reel 56 such as the component code matching is not accommodated in the reel bucket 51, the main body processing unit 42C displays that the replenishment reel is not accommodated on the touch panel 55A. That is, the main body processing unit 42C displays on the touch panel 55A that the storage unit 51A does not store the supply reel 56 that can be supplied to the tape feeder 30 expected to run out of components.

As shown in fig. 8, the main body processing unit 42C may change the color of the reel arrangement button 55E to a conspicuous color such as yellow as a display (a portion indicated by a dot in the drawing) that does not store the content. Thus, the operator can find the occurrence of the supply reel 56 to be newly stored in the reel bucket 51 by observing the change in the display of the reel arrangement button 55E. On the other hand, when the determination processing unit 72 determines that all the supply reels 56 having the identical component code or the like are accommodated in the reel bucket 51, the main body processing unit 42C maintains the display state of the reel arrangement button 55E.

In the state shown in fig. 8, when the reel arrangement button 55E is touched by the operator, as shown in fig. 9, the list display unit 73 (see fig. 7) of the main body processing unit 42C causes the touch panel 55A to display list information 55H in which the storage position number 63 is associated with the component code 82 (identification information) of the supply reel 56 to be stored in the storage portion 51A of the storage position number 63.

At this time, the distribution processing unit 74 obtains the empty storage unit 51A that does not store the supply reel 56, among the plurality of storage units 51A, based on the creation-related data D3. The dispensing processing unit 74 dispenses the component code 82 of the supply reel 56 to be stored to the acquired empty storage unit 51A. At the time of the distribution, the distribution processing unit 74 distributes the replenishment reels 56 having higher priority to execute the splicing operation in the order of ascending the storage position numbers 63 (order of 1, 2, 3 · 10) to the empty storage unit 51A. The distribution processing unit 74 increases the priority of the replenishment reel 56 that supplies the tape feeder 30, which is expected to take a shorter time before the component runs out, for example. Therefore, the distribution processing unit 74 distributes the supply reel 56 (component code 82) corresponding to the tape feeder whose expected time until the component runs out to the empty storage unit 51A having a smaller number. The distribution processing unit 74 may distribute the supply reels 56 having higher priority in descending order of the storage position numbers 63.

The assignment processing unit 74 outputs assignment information D5 indicating the assignment result to the list display unit 73. The list display unit 73 displays the list information 55H based on the assignment information D5 of the assignment processing unit 74. In the example shown in fig. 9, a state is shown in which the reel arrangement button 55E is pressed when all of the 10 accommodating portions 51A are empty accommodating portions 51A, that is, when one supply reel 56 is not accommodated in the reel bucket 51. As shown in fig. 9, in the leftmost column of the list information 55H, the storage position numbers 63 are displayed in ascending order (order of 1, 2, 3 · 10) from the top toward the bottom. Further, a check box 81 is displayed on the right side of the housing position number 63. Then, the component code 82 of the supply reel 56 to be stored is displayed on the right side of the check box 81. As described above, the component code 82 assigns a code whose expected time for component exhaustion is shorter (higher priority) to the smaller housing position number 63. The housing position numbers 63, the check boxes 81, and the component codes 82 are displayed in line by line in association with each other.

Further, a cancel button 83 and an ok button 84 are displayed on the lower right of the list information 55H. The cancel button 83 is a button for stopping the display of the list information 55H. When the cancel button 83 is touched, the list display unit 73 stops the display of the list information 55H and returns the touch panel 55A to the display state of fig. 8.

The ok button 84 is a button for storing the correspondence relation data displayed in the list information 55H in the associated data D3. When the decision button 84 is touched, the associated establishing processing unit 75 inputs the list information 55H from the list display unit 73, and stores the correspondence relationship between the storage position number 63 and the component code 82 displayed in the list information 55H in the associated establishing data D3. Thus, the creation related data D3 newly stores data in which the housing position number 63 is related to the component code 82. When the decision button 84 is touched, the list display unit 73 stops the display of the list information 55H and returns the touch panel 55A to the display state of fig. 8.

(4-1. case where all the supply reels 56 can be prepared)

In the replenishing operation of the replenishment reel 56, the worker of the splicing unit 5, for example, finds a state in which the display of the reel arrangement button 55E is changed (see fig. 8), and then moves to the reel placement fields of the production lines 2A and 2B. In the reel installation site, a supply reel 56 that is taken out from the storage by an operator in the storage is disposed. The operator of the splicing unit 5 touches the reel arrangement button 55E to display list information 55H (see fig. 9). The operator finds the supply reel 56 from the reel storage area, which is marked with the component code 82 identical to the component code 82 displayed in the list information 55H. The operator supplies the supply reel 56 having the component code 82 matching the component code to the storage portion 51A of each storage position number 63 in accordance with the display of the list information 55H. When the replenishment work is completed, the worker touches the determination button 84. Thus, the creation association processing unit 75 updates the creation association data D3 in accordance with the fact that the worker has received the supply reel 56 to be received in the receiving portion 51A of the receiving position number 63 in accordance with the contents of the list information 55H.

As described above, the worker moves the production line 2A while maintaining the list information 55H displayed, or searches for the supply reel 56 from the reel storage. Therefore, in the state where the list information 55H is displayed (see fig. 9), the display state can be maintained by invalidating the input or the like of the device other than the cancel button 83 and the confirm button 84, which may change the display state. For example, the main body processing unit 42C may invalidate the reading of the barcode 38 by the barcode reader 52 in the display state of the list information 55H so as not to start the stitching verification.

Alternatively, the barcode reader 52 may be enabled to read the barcode 38 in a state where the list information 55H is displayed, and the main body processing unit 42C may determine whether or not the component code 82 displayed in the list information 55H matches the component code 82 of the supply reel 56 from which the barcode 38 has been read. Further, when the supply reel 56 having the component code 82 matching therewith exists, the main body processing unit 42C may change the display of the corresponding component code 82 and the like in the list information 55H. Thus, the worker can easily find the supply reel 56 to be replenished by, for example, reading the barcode 38 of the supply reel 56 in the reel installation space and observing the display of the list information 55H. The operator can easily confirm the storage position number 63 in which the replenishment reel 56 is stored.

(4-2. in the case where all the supply reels 56 cannot be prepared)

In addition, the worker can use the check box 81 when the worker cannot prepare the replenishment reels 56 for all the component codes 82 displayed in the list information 55H. As shown in fig. 10, the operator touches a check box 81 that cannot be prepared, and checks the box. In the example shown in fig. 10, the check boxes 81 corresponding to "2", "8", and "9" of the storage position number 63 are checked. The case where preparation is not possible is assumed to be, for example, a case where there is no supply reel 56 required in the reel placement field, or a case where the time until the components are used up is short and there is no time to search for all supply reels 56.

When the ok button 84 is operated with the check box 81 checked, the association processing unit 75 does not associate the component code 82 checked (unable to prepare) with the corresponding storage position number 63. Thus, the storage position number 63 with a check added to the check box 81 is stored in the creation related data D3 as the empty storage section 51A, which is not the component code 82 of the replenishment reel 56 stored therein.

(4-3. additional supply when supply reel 56 remains in reel hopper 51)

In the example shown in fig. 9, the case where the tape reel arrangement button 55E is pressed when all of the 10 accommodating portions 51A are empty accommodating portions 51A is described. In contrast, a case will be described in which the reel arrangement button 55E is touched and operated in a state where the supply reel 56 remains in the reel bucket 51.

For example, a case is assumed where the worker moves to the vicinity of the reel installation site while pressing the splicing unit 5 and moving in the middle of the movement of the production line 2A. In this case, if the empty storage portion 51A exists in the reel bucket 51, the worker can replenish the replenishment reel 56 from the reel storage yard. In this case, even if the tape reel arrangement button 55E is not displayed in the non-storage display (dot display state) shown in fig. 8, the operator wants to operate the tape reel arrangement button 55E.

Therefore, as shown in fig. 11, even when the tape reel arrangement button 55E, which is normally displayed, is touched, the list display section 73 displays the storage position number 63 and the component code 82 corresponding to the storage position number 63 as the list information 55H. In this case, the list display unit 73 displays the list information 55H based on, for example, the latest assignment information D5. When the list information 55H is displayed, the list display unit 73 determines whether or not the replenishment reel 56 remains in the reel bucket 51, that is, whether or not the storage unit 51A that has stored the replenishment reel 56 exists, based on the associated setup data D3. When the stored storage section 51A exists, the list display section 73 displays the stored content on the touch panel 55A. For example, as shown in fig. 11, the list display unit 73 surrounds the part code 82 corresponding to the stored storage position number 63 with a frame, and displays an arrow on the left side of the part code 82 for the sake of visibility. Thus, the operator can determine the storage position number 63 and the component code 82, which have been stored or not stored, by observing the display of the component code 82.

Note that the reel arrangement button 55E of the list display unit 73 is not limited to the normal display, and even when a touch operation is performed in a state where the display is not stored as shown in fig. 8, the display of the stored component code 82 and the like is changed as in the case of fig. 11. As described above, the allocation processing unit 74 allocates the component codes 82 (replenishment reels 56) having higher priority in the order of ascending the storage position number 63 to the empty storage unit 51A at the time of allocation. In this case, for example, the assignment processing unit 74 assigns the component code 82, which is expected to be shorter until the component is used up, to the empty storage unit 51A having a smaller number with respect to the empty storage units 51A other than the stored storage unit 51A.

(4-4. display processing during mosaic check)

Next, a display process at the time of the mosaic check will be described. As described above, the main body processing section 42C starts the splice verification when the barcode 38 of the used reel 32 with the used component is read by the barcode reader 52. The main body processing unit 42C may be set so as not to start the splicing verification even if the barcode 38 of the old reel 32 is read before the mode is changed to a specific mode (for example, verification mode).

For example, as shown in fig. 12, in the normal display or verification mode, the main body processing unit 42C displays a display for reading the barcode 38 of the "filled used reel" (used reel 32 with used components) on the information display unit 55B. In this state, when the barcode 38 loaded on the tape reel 32 of the tape feeder 30 is read by the barcode reader 52, the main body processing unit 42C displays the read barcode 38 on the barcode display unit 55C as shown in fig. 12.

The main body processing unit 42C retrieves data corresponding to the read barcode 38 from the component end information D4 stored in the storage device 77, and acquires the component code 82 of the used reel 32 with the component end. The main body processing unit 42C searches the storage position number 63 for storing the supply reel 56 of the component code 82 matching the acquired component code 82 from the setup related data D3. Thus, the main body processing unit 42C can acquire the storage position number 63 of the storage portion 51A in which the supply reel 56 capable of performing the splicing operation for the reel 32 (supply target reel) with the component end of the read barcode 38 is stored, from the setup relation data D3.

When the supply reel 56, which can be spliced (component code 82 is matched), is not present in the reel hopper 51, the main body processing unit 42C displays the contents thereof on the information display unit 55B (see fig. 13). Thus, for example, the operator can find out that the reel 32 for reading the barcode 38 is wrong, and can take appropriate measures such as checking the positions of the grooves S1 to Sn. The main body processing unit 42C returns to the display state of fig. 12 after the display shown in fig. 13 is maintained for a certain time.

In addition, when the supply reel 56 capable of performing splicing operation is present in the reel bucket 51, the main body processing unit 42C displays a content urging reading of "a barcode of a new supply reel for splicing operation" on the information display unit 55B as shown in fig. 14. Then, the main body processing unit 42C displays the storage position number 63 acquired from the associated data D3 and the corresponding element code 82 on the touch panel 55A. In the illustrated example, the storage position number 63 ("No. 1") and the component code 82(C5R55a001) are displayed on the information display portion 55B between the advance notice display portion 55G and the reel arrangement button 55E. Thus, the operator can easily find the supply reel 56 usable for the splicing operation by observing the housing position number 63 and the component code 82 displayed on the touch panel 55A.

Further, the main body processing unit 42C changes the display (portion indicated by a dot in the drawing) of the notice display unit 55G corresponding to the reel 32 from which the barcode 38 is read. The main body processing unit 42C can determine which notice display unit 55G corresponds to the barcode 38 by searching the data corresponding to the read barcode 38 from the component end information D4. This allows the operator to confirm whether or not the splicing operation can be performed on the reel 32 to be supplied as desired. The worker can quickly and reliably perform the splice check by using the supply reel 56 of the storage position number 63 of No. 1.

(5. Effect of the structure of the first embodiment)

The splicing unit 5 of the first embodiment includes: a reel bucket 51 having a plurality of accommodating portions 51A for accommodating a plurality of supply reels 56, respectively; a splicing device 50 for executing a splicing operation of the carrier tape 31 loaded on the tape feeder 30 (supply target tape reel) 32 of the tape feeder 30 and the carrier tape 31 of any one supply tape reel 56 of the plurality of supply tape reels 56 with respect to the tape feeder 30 mounted on the electronic component mounting apparatus 13; a barcode reader 52 (detection means) that detects the barcode 38 (identification information) that the reel 32 has; a touch panel 55A (display unit) for displaying information related to the splicing work (notice display unit 55G and the like); the main body processing unit 42C (display processing unit) displays, on the touch panel 55A, the storage position number 63 (position information) of the storage portion 51A in which the supply reel 56 to be used for the splicing operation is stored, based on the barcode 38 of the reel 32 detected by the barcode reader 52.

Thus, the main body processing unit 42C (display processing unit) displays, on the touch panel 55A (display unit), the storage position number 63 (position information) of the storage portion 51A in which the supply reel 56 to be used for the splicing operation is stored, based on the barcode 38 (identification information) of the reel 32 (supply target reel) detected by the barcode reader 52 (detection device). Thus, the worker can reduce the work load of searching for a usable supply reel 56 from among the plurality of supply reels 56 in the reel bucket 51 before starting the splicing work by checking the display of the touch panel 55A.

The splicing unit 5 further includes a touch panel 55A (operation unit) that receives an operation from an operator, and the main body processing unit 42C includes: a list display unit 73 that displays, on the touch panel 55A, the storage position numbers 63 that identify the plurality of storage units 51A as position information of the storage units 51A, and displays, on the touch panel 55A, the component codes 82 (identification information) for identifying the supply reels 56 to be stored in the storage units 51A of the storage position numbers 63 in association with the storage position numbers 63; and a creation association processing unit 75 that generates creation association data D3 associating the storage position number 63 with the component code 82, in response to an operation of the touch panel 55A that has stored the supply reel 56 to be stored in the storage portion 51A of the storage position number 63 in accordance with the content displayed on the list display unit 73.

Thus, the operator can appropriately store the supply reel 56 in the designated storage portion 51A by checking the correspondence between the storage position number 63 displayed on the touch panel 55A by the list display unit 73 and the component code 82 (identification information) of the supply reel 56 (see fig. 9). Then, the creation association processing unit 75 generates creation association data D3 associating the housing position number 63 with the component code 82, in response to the presence of an operation to house the content. Thus, the main body processing unit 42C can check which replenishment tape reel 56 is stored in the storage portion 51A of which storage position number 63 by referring to the creation-related data D3.

The reel 32 (reel to be supplied) includes the barcode 38 as identification information, the splicing unit 5 includes the barcode reader 52 as a detection device that reads the barcode 38, and the main body processing unit 42C (display processing unit) displays, on the touch panel 55A, the storage position number 63 of the storage portion 51A in which the supply reel 56 that can perform splicing work with respect to the reel 32 from which the barcode 38 is read is stored as position information of the storage portion 51A, based on the barcode 38 of the reel 32 read by the barcode reader 52 and the associated data D3.

Thus, the worker can confirm the storage position number 63 (see fig. 14) of the supply reel 56 usable for the splicing operation by reading the barcode 38 of the reel 32 by the barcode reader 52 and then observing the display of the touch panel 55A. This allows the operator to easily find a usable replenishing reel 56 from among the plurality of replenishing reels 56 in the reel bucket 51.

The main body processing unit 42C further includes: an acquisition processing unit 71 that acquires, from the host computer 3 that manages the electronic component mounting machine 13, identification information of the supply reel 56 (the component code 82 included in the component end information D4) for which the splicing operation should be executed; the determination processing unit 72 determines whether or not the reel bucket 51 contains the supply reel 56 corresponding to the component code 82 of the acquired component end information D4 based on the set-up related data D3 in response to the acquisition processing unit 71 newly acquiring the component end information D4. The main body processing unit 42C displays on the touch panel 55A the fact that the corresponding replenishment reel 56 is not stored in the reel bucket 51 when the determination processing unit 72 determines that the corresponding replenishment reel 56 is not stored.

When the component end information D4 of the supply reel 56 on which the splicing operation is to be executed is newly acquired from the host computer 3 by the acquisition processing unit 71, the determination processing unit 72 determines whether or not the supply reel 56 corresponding to the component code 82 of the component end information D4 is accommodated in the reel bucket 51. When not stored, the main body processing unit 42C displays the content that is not stored on the touch panel 55A (see fig. 8). Thus, the operator can confirm that the replenishment reel 56 that needs to be newly stored in the reel bucket 51 has occurred by observing the display on the touch panel 55A.

When detecting that the supply reel 56 to be stored has been already stored in the reel bucket 51 based on the creation-related data D3, the list display unit 73 displays on the touch panel 55A the fact that the supply reel 56 to be stored has been already stored.

When detecting that the supply reel 56 to be stored is already stored in the reel bucket 51 based on the associated data D3, the list display unit 73 displays the stored data on the touch panel 55A (see fig. 11). Thus, the operator can easily distinguish the supply reel 56 that has been stored in the reel bucket 51 from the supply reel 56 that should be newly stored in the empty storage portion 51A by observing the display on the touch panel 55A, and can more quickly and reliably prepare the supply reel 56.

The main body processing unit 42C further includes a distribution processing unit 74, and the distribution processing unit 74 acquires an empty storage unit 51A that does not store the supply reel 56 among the plurality of storage units 51A based on the creation-related data D3, distributes the supply reel 56 to the acquired empty storage unit 51A, and distributes the supply reel 56 having a higher priority to be subjected to the splicing work in ascending or descending order of the storage position number 63 in the empty storage unit 51A at the time of distribution.

Thus, the reel bucket 51 stores the supply reels 56 having a high priority in ascending or descending order of the storage position number 63 in the empty storage portion 51A in which the supply reels 56 are not stored. By starting the use of the supply reel 56 of the storage portion 51A having the storage position number 63 smaller or larger, the operator can perform the splicing operation with a high priority (for example, the expected time before the component runs out is short), and the stop of the production line can be prevented more reliably.

The association creation processing unit 75 does not associate the component code 82 of the replenishment reel 56 that cannot be prepared with the storage position number 63, in response to the touch panel 55A receiving, from the operator, an operation in which the component code 82 of the replenishment reel 56 that cannot be prepared is associated with the component code 82 displayed on the touch panel 55A by the list display unit 73.

Thus, the worker can avoid saving the associated data D3 by inputting the contents of the replenishment tape reel 56 that cannot be prepared into the check box 81 of the touch panel 55A. For example, when the worker obtains the supply reel 56 in a supply reel yard or the like, but does not have the desired supply reel 56 and moves for the next work, the worker performs an operation that cannot prepare the supply reel 56. Thus, the main body processing unit 42C can determine the storage unit 51A of the replenishment reel 56 that cannot be prepared as the empty storage unit 51A based on the associated data D3, and use the empty storage unit 51A for next and subsequent dispensing.

Further, when detecting that the reel bucket 51 does not accommodate the supply reel 56 to be used in the splicing work based on the barcode 38 of the reel 32 detected by the barcode reader 52 and the setup related data D3, the main body processing unit 42C displays on the touch panel 55A that the reel bucket 51 does not accommodate the supply reel 56 to be used in the splicing work.

Thus, the operator can confirm that the supply reel 56 capable of performing the splicing operation for the reel 32 in which the barcode 38 is detected by the barcode reader 52 is not accommodated in the reel bucket 51 by observing the display on the touch panel 55A. This enables the operator to take appropriate measures such as giving priority to the splicing operation for the other reels 32.

(second embodiment)

(6. Structure of splicing Unit 105)

Next, a second embodiment of the splicing unit of the present invention will be described. Fig. 15 shows a splicing unit 105 of the second embodiment. In the following description, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The splicing unit 105 of the second embodiment has the same configuration as the splicing unit 5 of the first embodiment shown in fig. 4, but differs in the processing content of the main body processing unit 42C. The main body processing portion 42C of the second embodiment does not associate the storage position number 63 of the reel bucket 51 with the component code 82. Therefore, the creation related data D3 is not stored in the storage device 77. In fig. 15, the communication unit 54 is not shown.

As shown in fig. 15, the main body processing unit 42C of the second embodiment includes an acquisition processing unit 71. The acquisition processing unit 71 collects the component end information D4 of the tape feeders 30 of which the component end is expected for 10 or more pieces and periodically acquires the information from the host computer 3. The acquisition processing unit 71 stores the acquired component end information D4 in the storage device 77.

Fig. 16 shows an example of a display screen of the touch panel 55A according to the second embodiment when viewed from the front. As shown in fig. 16, the acquisition processing unit 71 displays the notice display unit 55G on the touch panel 55A based on the element-end information D4, as in the first embodiment. The tape reel arrangement button 55E (see fig. 6) is not displayed on the touch panel 55A according to the second embodiment.

(6-1. display treatment)

Fig. 18 shows a display process performed by the main body processing unit 42C according to the second embodiment. The main body processing unit 42C of the second embodiment starts the display process shown in fig. 18 by reading the barcode 38 of the supply reel 56. First, in step (hereinafter, abbreviated as "S") 11 shown in fig. 18, the main body processing unit 42C detects that the barcode 38 of the supply reel 56 is read by the barcode reader 52. When any of the barcodes 38 of the supply reels 56 stored in the reel bucket 51 is read in the display state shown in fig. 16, the main body processing unit 42C changes the display of the notice display unit 55G based on the read barcode 38 (S12).

The main body processing unit 42C determines the advance notice display unit 55G of the reel 32 to which the supply of the splicing work can be performed, such as the supply reel 56 from which the barcode 38 is read matching the component code 82. As described above, the component use-up information D4 stores therein data in which the module number, slot number, barcode 38, component code 82, and the like of the electronic component mounting apparatus 13 are associated with each other. Therefore, the main body processing unit 42C can detect the corresponding notice display unit 55G by searching the information of the barcode 38 read by the barcode reader 52 from the component-end information D4.

As shown in fig. 17, the main body processing unit 42C changes the display of the touch panel 55A so that only the corresponding notice display unit 55G obtained from the element-end information D4 is displayed. In the example shown in fig. 17, only the upper 2 announcement display sections 55G of the 5 announcement display sections 55G display the module numbers and the like. In this case, the tape feeder 30 to which the module number and the slot number displayed on the upper 2 advance notice display units 55G are attached can perform the splicing operation using the supply reel 56 in which the barcode 38 is read by the barcode reader 52. This reduces the workload of the worker for finding the supply target reel 32 (supply reel 56) that can be spliced out of the supply reels 56 from which the barcode 38 is read. As shown in fig. 17, the main body processing unit 42C displays the component code 82 of the supply reel 56 of the read barcode 38 on the touch panel 55A for confirmation.

Next, the main body processing unit 42C determines the display time during which the display state shown in fig. 17 continues (S13). The main body processing unit 42C determines whether or not the display state shown in fig. 17 continues for, for example, 10 seconds or longer (S13). The time period of 10 seconds is set based on the time required for the operator to visually confirm only the display focused on the advance notice display section 55G capable of performing the splicing operation shown in fig. 17. When 10 seconds or more has elapsed (S13: YES), the main body processing unit 42C returns the display of the notice display unit 55G to the state shown in FIG. 16 (S14), and the display processing shown in FIG. 18 is ended.

On the other hand, when the main body processing unit 42C determines that the display time is less than 10 seconds (no in S13), it determines whether or not the barcode 38 of the supply reel 56 stored in the reel bucket 51 has been newly read (S15). When there is no new reading (no in S15), the main body processing unit 42C again determines the display time in S13.

When the main body processing unit 42C determines that a new reading is made (S15: yes), the display of the notice display unit 55G is updated so as to correspond to the newly read barcode 38 (S12). After updating the display of the notice display unit 55G, the main body processing unit 42C resets the measured display duration, and starts the process from S13 again.

(6-2. replenishment work by worker)

Next, an example of a replenishment operation by a worker using the splicing unit 105 of the second embodiment will be described. For example, the storage location side device 4 provided in the storage of the supply reel 56 displays information (slot numbers, component codes 82, and the like) of a plurality of (for example, several tens or more) tape feeders 30 expected to run out of components on the basis of the component end information D4 acquired from the host computer 3. The storage location side device 4 displays, for example, information indicating that the expected time for component exhaustion is short in order.

When the supply reel 56 in the reel bucket 51 runs out, the worker of the splicing unit 105 moves to the storage and confirms the display content of the storage-site-side device 4. For example, the operator finds out the replenishment reel 56 of the top 10 pieces of higher priority from among the tape feeders 30 expected to run out of components displayed on the storage site side device 4 from the storage, and stores the replenishment reel in the reel bucket 51. The operator stores the replenishing reels 56 in the storage portions 51A in ascending order "1, 2, 3 · 10" of the storage position number 63, for example, in order from the highest priority. Thus, the replenishment reel 56 having a higher priority (having a short expected time to empty components) is accommodated in the accommodating portion 51A in ascending order of the accommodating position number 63 in the reel bucket 51. Therefore, in this state, if the worker efficiently splices the supply reel 56 accommodated in the reel bucket 51 in the production line 2A, the worker resultantly has the same result as the case where the supply reel 56 having a high priority is supplied.

The operator can temporarily and appropriately store the supply reel 56 having a high priority in the reel bucket 51 without considering the storage position number 63. That is, the operator can store the supply reel 56 having a high priority in the reel bucket 51 without considering the relationship between the storage position number 63 and the supply reel 56. This allows the operator to efficiently load the supply reel 56 into the reel bucket 51 and to store the supply reel 56 having a high priority.

Further, the operator may consider a case where the replenishment reel 56 is stored in the reel bucket 51, taking into consideration various work situations, based on the display contents of the storage site-side device 4. Therefore, it is impossible to predict what component code 82 is stored in the reel bucket 51 in the supply reel 56. On the other hand, the main body processing unit 42C needs to find the supply target reel 32 that can be spliced to the supply reel 56 from which the barcode 38 is read out from among the production lines 2A and 2B. Therefore, unlike the first embodiment, the main body processing unit 42C can download more component use-up information D4 from the host computer 3. Alternatively, the main body processing unit 42C may appropriately inquire of the host computer 3 the slot number and the like of the reel 32 to be replenished, which can perform the splicing operation using the replenishing reel 56 from which the barcode 38 is read. In this case, the splicing unit 105 may not have the component-end information D4 in the storage device 77.

Next, the worker stores the upper 10 supply reels 56 having a high priority in the reel bucket 51, moves the reel bucket to the production line 2A, and reads the barcode 38 from the supply reel 56 having a small storage position number 63, for example. Thus, the notice display unit 55G displays only the supply reel having the component code 82 matching (see fig. 17). For example, if the displayed advance notice display unit 55G is a position close to the current position, the operator performs the splicing operation.

When all of the displayed notice display units 55G are at a remote distance, the operator reads the barcode 38 of the other supply reel 56. When the barcode 38 is newly read in the display state shown in fig. 17, the main body processing unit 42C updates the display of the notice display unit 55G (S15: yes → S12 in fig. 18). The main body processing unit 42C displays only the notice display unit 55G corresponding to the newly read barcode 38. Thus, the operator can find the reel 32 to be replenished close to the current position by reading the barcode 38 a plurality of times and checking the display of the advance notice display unit 55G, and can efficiently perform the splicing operation.

As described above, in the splicing unit 5 of the first embodiment, the work load of finding the supply reel 56 corresponding to the reel 32 to be supplied from the reel bucket 51 is reduced. In contrast, in the splicing unit 105 of the second embodiment, the work load of finding the supply target reel 32 corresponding to the supply reel 56 housed in the reel bucket 51 can be reduced. The splicing units 5 and 105 may have the functions of both the first and second embodiments.

(7. Effect of the structure of the second embodiment)

The splicing unit 105 of the second embodiment includes: a reel bucket 51 that accommodates a plurality of supply reels 56; a splicing device 50 for executing a splicing operation of the carrier tape 31 loaded on the tape feeder 30 (supply target tape reel) 32 of the tape feeder 30 and the carrier tape 31 of any one supply tape reel 56 of the plurality of supply tape reels 56 with respect to the tape feeder 30 mounted on the electronic component mounting apparatus 13; a barcode reader 52 (detection device) that detects the barcode 38 (identification information) included in the supply reel 56; a touch panel 55A (display unit) for displaying information relating to the splicing work; the main body processing unit 42C (display processing unit) displays, on the touch panel 55A, a notice display unit 55G (position information) of the reel 32 that can perform splicing work using the detected supply reel 56, based on the barcode 38 of the supply reel 56 detected by the barcode reader 52.

Thus, the main body processing unit 42C displays the notice display unit 55G of the supply target reel 32 that can perform the splicing operation using the detected supply reel 56 on the touch panel 55A based on the barcode 38 of the supply reel 56 detected by the barcode reader 52. Thus, the worker can reduce the work load of searching for the reel 32 to be replenished from among the plurality of electronic component mounting machines 13 in the production lines 2A and 2B by checking the display of the touch panel 55A.

When the barcode reader 52 (detection device) detects the barcode 38 (identification information) of the supply reel 56 accommodated in the reel bucket 51, the main body processing unit 42C causes the touch panel 55A (display unit) to display, as the position information of the reel 32 to be supplied for the splicing work, the slot number of the tape feeder 30 to which the tape feeder 30 is attached to the electronic component mounting machine 13, that is, the slot number of the tape feeder 30 capable of performing the splicing work using the supply reel 56 from which the barcode 38 is detected.

Thus, the main body processing unit 42C displays the slot number of the tape feeder 30 on the touch panel 55A, which enables the splicing operation using the supply reel 56 detected by the barcode reader 52 (see fig. 17). Thus, the worker can check the slot number of the tape feeder 30 (the supply target reel 32) by detecting the barcode 38 of any supply reel 56 using the barcode reader 52 and then observing the display on the touch panel 55A. Further, the worker can reduce the work load of searching for the supply target reel 32 from among the plurality of electronic component mounting machines 13 in the production lines 2A and 2B by searching for the supply target reel 32 based on the slot number.

In addition, the main body processing unit 42C (display processing unit) updates the information of the slot number in a state where the slot number is displayed, in response to a new detection of the barcode 38 of the supply reel 56 accommodated in the reel bucket 51 by the barcode reader 52 (detection device).

Thus, even if the worker detects the barcode 38 and displays the slot number by the barcode reader 52 once, the worker can update the information of the slot number by newly detecting the barcode 38. Thus, the operator can check the slot number by successively detecting the barcode 38 without waiting for the display to be completed.

For example, the receiving portion 51A may be a shelf board that is arranged in parallel in the vertical direction of the reel bucket 51. Alternatively, the storage portion 51A may be configured to be arranged in parallel in the vertical direction and the horizontal direction of the reel 51. In this case, the housing position number 63 may be a number in which the number of stages is added to the housing position number 63.

In the first embodiment, when the supply reel 56 is completely stored in the reel bucket 51, the list display unit 73 displays the stored contents on the touch panel 55A (see fig. 8), but may not display the contents.

In the first embodiment, when the supply reel 56 that can be spliced is not accommodated in the reel bucket 51, the main body processing unit 42C displays the contents thereof on the touch panel 55A (see fig. 13), but may not display the contents.

In the second embodiment, the main body processing unit 42C updates the information on the notice display unit 55G when the barcode 38 is newly read in a state where only the corresponding notice display unit 55G is displayed (see fig. 17), but the update may not be performed.

In each of the above embodiments, the electronic component supply system 1 may be configured without at least 1 of the storage-site-side apparatus 4, the solder printing apparatus 11, the mounting inspection apparatus 14, and the reflow apparatus 15.
