Below, an embodiment of the present invention will be described in detail with reference to the drawings as a form for implementing the present invention.

Figure 1 shows a substrate-related operation machine 10. The substrate-related operation machine 10 has one system base 14 and two placement machines 16 arranged side by side on the system base 14. In the following explanation, the direction in which the two placement machines 16 are lined up is referred to as the X-axis direction, and the horizontal direction perpendicular to that direction is referred to as the Y-axis direction.

Each mounting machine 16 mainly comprises a mounting machine main body 20, a transport device 22, a mounting head moving device (hereinafter sometimes abbreviated as "moving device") 24, a mounting head 26, and a supply device 28. The mounting machine main body 20 is composed of a frame 30 and a beam 32 suspended on the frame 30.

The transport device 22 is equipped with two

conveyor devices

40, 42. The two

conveyor devices

40, 42 are arranged on the frame 30 so as to be parallel to each other and extend in the X-axis direction. Each of the two

conveyor devices

40, 42 transports a circuit board supported by each

conveyor device

40, 42 in the X-axis direction by an electromagnetic motor (see FIG. 2) 44. The circuit board transported by each

conveyor device

40, 42 is held at a predetermined position by a board holding device (see FIG. 2) 46.

The moving device 24 is an XY robot type moving device. The moving device 24 is equipped with an electromagnetic motor (see FIG. 2) 52 that slides the slider 50 in the X-axis direction, and an electromagnetic motor (see FIG. 2) 54 that slides it in the Y-axis direction. The mounting head 26 is attached to the slider 50, and the mounting head 26 moves to any position on the frame 30 by the operation of the two

electromagnetic motors

52, 54.

The mounting head 26 mounts electronic components on the circuit board. The mounting head 26 has a suction nozzle 60 provided on its bottom surface. The suction nozzle 60 is connected to a positive/negative pressure supply device (see FIG. 2) 66 via negative pressure air and positive pressure air passages. The suction nozzle 60 sucks and holds the electronic component by negative pressure, and releases the held electronic component by positive pressure. The mounting head 26 also has a nozzle lifting device (see FIG. 2) 68 that raises and lowers the suction nozzle 60. The nozzle lifting device 68 allows the mounting head 26 to change the vertical position of the electronic component it holds. The suction nozzle 60 is detachable from the mounting head 26, and can be replaced depending on the size of the electronic component, etc.

The supply device 28 is a feeder type supply device and is disposed at the end of the frame 30. The supply device 28 has a plurality of tape feeders 70. The tape feeders 70 house reels 72 around which taped components are wound. The taped components are electronic components taped to a carrier tape. The tape feeders 70 feed the taped components using a feed device (see FIG. 3) 76. In this way, the feeder type supply device 28 supplies electronic components at the supply position by feeding out the taped components. The tape feeders 70 are detachable from the frame 30, making it possible to accommodate replacement of electronic components, etc.

The substrate-related operating machine 10 also includes a control device 80, as shown in FIG. 2. The control device 80 includes a controller 82 and a plurality of drive circuits 86. The plurality of drive circuits 86 are connected to the

electromagnetic motors

44, 52, 54, the substrate holding device 46, the positive and negative pressure supply device 66, the nozzle lifting device 68, and the sending device 76. The controller 82 includes a CPU, ROM, RAM, etc., and is mainly a computer, and is connected to the plurality of drive circuits 86. As a result, the operation of the transport device 22, the moving device 24, etc. is controlled by the controller 82.

With this structure, the placement machine 16 places electronic components on the circuit board. Specifically, first, the circuit board is carried into the placement machine 16. Then, in response to a command from the controller 82, the circuit board is transported to the work position, where it is held by the board holding device 46. Also, in response to a command from the controller 82, the tape feeder 70 feeds out the taped components and supplies the electronic components at the supply position. Then, in response to a command from the controller 82, the placement head 26 moves above the supply position of the electronic components and suction-holds the electronic components with the suction nozzle 60. Next, the placement head 26 moves above the circuit board and places the held electronic components on the circuit board. Then, when the electronic components to be placed are placed on the circuit board, the board holding device 46 releases the circuit board from its hold, and the circuit board is taken out of the placement machine.

In this way, the placement machine 16 performs the mounting operation of mounting electronic components on the circuit board. For this reason, it is necessary to attach to the tape feeder 70 a reel (hereinafter referred to as the "required reel") 72 on which a tape component that contains the electronic components required for the mounting operation is wound. Therefore, before the placement machine 16 performs the mounting operation of the electronic components, a worker uses a kitting stand 100 (see FIG. 3) to attach the required reel 72 to the tape feeder 70 (hereinafter referred to as the "reel attachment operation").

More specifically, as shown in FIG. 3, the kitting stand 100 has a mounting base 110, a stand 112, and an upper rail 114. The mounting base 110 supports the bottom surface of the tape feeder 70, and the bottom surface of the tape feeder 70 is placed on the upper surface of the mounting base 110. The stand 112 is erected on the upper surface of the mounting base 110 and supports the side surface of the tape feeder 70 placed on the mounting base 110. An upper rail 114 is disposed at the upper end of the stand 112, and the upper end of the tape feeder 70 placed on the mounting base 110 fits into the upper rail 114. The tape feeder 70 is set in the kitting stand 100 in this position. A bracket 116 is fixed to the front side edge of the stand 112 so as to cover the front end surface of the tape feeder 70 set in the kitting stand 100, and a connector connection portion 118 is disposed on the bracket 116. A connector (see FIG. 6) 120 is provided at the front end of the tape feeder 70. Therefore, when the tape feeder 70 is set on the kitting stand 100, the connector 120 of the tape feeder is connected to the connector connection portion 118. This allows the tape feeder 70 to be set in a positioned state on the kitting stand 100 and electrically connected.

Furthermore, a PC 130 is connected to the connector connection part 118 of the kitting stand 100 via a cable 122, and transmits and receives data to and from a tape feeder 70 set in the kitting stand 100. The tape feeder 70 stores identification information of the tape feeder 70 (hereinafter referred to as "feeder ID") and information indicating the width of the tape feeder 70 (hereinafter referred to as "width information"). When the tape feeder 70 is set in the kitting stand 100, the feeder ID and width information are output to the PC 130. The PC 130 then stores the feeder ID and the width information in association with each other. When the reel attachment work is performed, a tape feeder 70 without a reel 72 attached is set in the kitting stand 100.

In addition, the PC 130 stores information necessary for the reel installation work, and stores identification information of the necessary reel 72 as information necessary for the reel installation work. The identification information of the necessary reel is identification information of the electronic component of the tape component wound on the necessary reel. The PC 130 displays the identification information of the necessary reel on the monitor (not shown) of the PC 130. This allows the worker to prepare the reel 72 according to the identification information displayed on the monitor of the PC 130. A sticker or the like showing the identification information in barcode is attached to the reel 72, and the worker identifies the necessary reel by the affixed sticker. The worker then attaches the prepared necessary reel to the tape feeder 70 set in the kitting stand 100. A barcode reader (not shown) is also connected to the PC 130, and the worker uses the barcode reader to read the barcode on the sticker attached to the necessary reel. Then, PC 130 stores the identification information of the read barcode of the required reel (hereinafter, referred to as "component information") in association with the feeder ID and width information. As a result, in kitting stand 100, the required reel, i.e., a reel on which taped components 98 that contain electronic components required for the next mounting operation are wound, is mounted on tape feeder 70, and the component information of the required reel and the feeder ID and width information of tape feeder 90 are stored in PC 130.

Then, when the worker loads the required reel into the tape feeder 70, the tape feeder 70 is stored in the feeder storage 150 shown in Figures 4 and 5. Note that Figure 4 is a perspective view of the feeder storage 150, and Figure 5 is a front view of the feeder storage 150. The feeder storage 150 is a shelf-shaped rack consisting of an upper shelf and a lower shelf, and a plurality of slots 152 are formed in each of the upper shelf and the lower shelf so as to extend in the depth direction. Note that the same number of slots 152, for example 50 slots 152, are formed in each of the upper shelf and the lower shelf. The width of the slot 152 is set to a width that can store an 8 mm wide tape feeder (hereinafter referred to as "8 mm feeder 70a") (see Figure 6), and one 8 mm feeder 70a is stored in one slot 152. Additionally, a 16 mm wide tape feeder (hereinafter referred to as "16 mm feeder 70b") (see FIG. 7) is stored in two adjacent slots 152. Additionally, a 24 mm wide tape feeder (hereinafter referred to as "24 mm feeder 70c") (see FIG. 8) is stored in three adjacent slots 152. In this way, the feeder storage 150 stores multiple types of tape feeders 70 with different widths.

In addition, a connector connection section 156 is provided corresponding to each of the multiple slots 152, to which the connector 120 of the tape feeder 70 stored in each slot 152 is connected. As a result, when a tape feeder 70 is stored in a slot 152, the connector 120 of the tape feeder 70 is connected to the connector connection section 156, and the tape feeder 70 stored in the slot 152 and the feeder storage case 150 are electrically connected. In addition, an LED 158 is provided above each of the multiple slots 152 corresponding to each of the multiple slots 152. The feeder storage case 150 is connected to the PC 130, and the LED 158 is turned on in accordance with commands from the PC 130.

With this structure, the feeder storage 150 notifies the position of the slot 152 in which the tape feeder 70 with the required reel is to be stored, based on width information indicating the width of the tape feeder 70. In more detail, the PC 130 stores the position and width information of the slots 152 of the tape feeders 70 stored in the feeder storage 150. For example, as shown in FIG. 6, the PC 130 stores that 8 mm feeders 70a are installed in

slots

1, 3, and 6-10. Therefore, the PC 130 recognizes that

slots

2, 4, and 5 are slots in which no tape feeder 70 is installed (hereinafter referred to as "empty slots").

When the tape feeder 70 is set on the kitting stand 100, the PC 130 stores the feeder ID of the tape feeder 70 set on the kitting stand 100 in association with the width information. At this time, the PC 130 searches for a slot 152 capable of accommodating the tape feeder 70 of the width indicated by the width information based on the width information. For example, when the width information indicates an 8 mm feeder 70a, the PC 130 searches for

empty slots

2, 4, and 5 as slots 152 capable of accommodating the 8 mm feeder 70a. Then, as shown in FIG. 6, the PC 130 turns on the LED 158 of one of the

slots

2, 4, and 5, for example, slot 2, which has the smallest slot number. The PC 130 also displays a comment on the monitor of the PC 130 indicating that the intended storage position of the tape feeder 70 set on the kitting stand 100 is slot 2. This allows the operator to store the 8 mm feeder 70a in the empty slot without hesitation. When the tape feeder 70 is stored in the slot 2, that is, when the connector 120 of the tape feeder 70 is connected to the connector connection part 156 corresponding to the slot 2, the tape feeder 70 outputs the feeder ID and width information to the PC 130. As a result, the PC 130 associates and stores the position of the slot corresponding to the connector connection part 156 to which the connector 120 of the tape feeder 70 is connected, the feeder ID, and the width information.

Also, when the width information of the tape feeder 70 set in the kitting stand 100 indicates the 16 mm feeder 70b, the PC 130 searches for a slot capable of accommodating the 16 mm feeder 70b, that is, two adjacent empty slots. At this time, for example, as shown in FIG. 7, the PC 130 searches for

slots

4 and 5 as slot 152 capable of accommodating the 16 mm feeder 70b. Then, the PC 130 turns on the LED 158 of slot 5, which corresponds to the connector connection portion 156 to which the connector 120 of the 16 mm feeder 70b is connected, of

slots

4 and 5. The connector 120 of the 16 mm feeder 70b is disposed in a position offset to the right side of the front end surface of the feeder body 75 of the 16 mm feeder 70b, and when the 16 mm feeder 70b is accommodated in

slots

4 and 5, the connector 120 of the 16 mm feeder 70b is connected to the connector connection portion 156 corresponding to slot 5. Therefore, PC 130 lights up LED 158 for slot 5 out of

slots

4 and 5. PC 130 also displays a comment on the monitor of PC 130 indicating that the intended storage position of tape feeder 70 set in kitting stand 100 is slot 5. This allows the worker to store 16 mm feeder 70b in an empty slot without hesitation. In particular, by lighting up slot 5 of connector connection portion 156 to which connector 120 of 16 mm feeder 70b is connected, connector 120 of 16 mm feeder 70b can be appropriately connected to connector connection portion 156 of slot 5.

Also, when the width information of the tape feeder 70 set in the kitting stand 100 indicates the 24 mm feeder 70c, the PC 130 searches for a slot capable of accommodating the 24 mm feeder 70c, that is, three adjacent empty slots. At this time, for example, as shown in FIG. 8, the PC 130 searches for

slots

7, 8, and 9 as slot 152 capable of accommodating the 24 mm feeder 70c. Then, the PC 130 turns on the LED 158 of slot 8, which corresponds to the connector connection portion 156 to which the connector 120 of the 24 mm feeder 70c is connected, among the

slots

7, 8, and 9. The connector 120 of the 24 mm feeder 70c is disposed in the center of the front end surface of the feeder body 75 of the 24 mm feeder 70c, and when the 24 mm feeder 70c is accommodated in the

slots

7, 8, and 9, the connector 120 of the 24 mm feeder 70c is connected to the connector connection portion 156 corresponding to the slot 8. Therefore, the PC 130 lights up the LED 158 of slot 8 out of

slots

7, 8, and 9. The PC 130 also displays a comment on the monitor of the PC 130 indicating that the intended storage position of the tape feeder 70 set in the kitting stand 100 is slot 8. This allows the worker to store the 24 mm feeder 70c in an empty slot without hesitation. In particular, by lighting up slot 8 of the connector connection portion 156 to which the connector 120 of the 24 mm feeder 70c is connected, the connector 120 of the 24 mm feeder 70c can be appropriately connected to the connector connection portion 156 of slot 8.

In addition, the PC 130 notifies the slots located within a predetermined area of the feeder storage 150 according to the type of circuit board to be produced by turning on the LED 158 as the slots where the tape feeders 70 are planned to be stored. In detail, the PC 130 stores the number and feeder width of the tape feeders 70 to be used when producing the circuit board A in the next mounting operation. For example, the PC 130 stores the number and feeder width of the tape feeders 70 to be used when producing the circuit board A as follows: 8 mm feeders 70a: 4 units, 16 mm feeders 70b: 3 units, and 24 mm feeder 70c: 1 unit. As shown in FIG. 9, the planned storage positions of the tape feeders 70 to be used when producing the circuit board A are set to slots 1 to 15. In addition, the planned storage position of the 8 mm feeder 70a used when creating the circuit board A is set to slots 1 to 4, the planned storage position of the 16 mm feeder 70b is set to slots 6 to 11, and the planned storage position of the 24 mm feeder 70c is set to slots 13 to 15. Therefore, the PC 130 lights up the LED 158 corresponding to any one of the slots 1 to 4 as the planned storage position of the 8 mm feeder 70a used when creating the circuit board A. In addition, the PC 130 lights up the LED 158 corresponding to any one of the

slots

7, 9, and 11 of the slots 6 to 11 as the planned storage position of the 16 mm feeder 70b used when creating the circuit board A. In addition, the PC 130 lights up the LED 158 corresponding to the slot 14 of the slots 13 to 15 as the planned storage position of the 24 mm feeder 70c used when creating the circuit board A.

Furthermore, for example, PC 130 stores the number and feeder width of tape feeders 70 to be used when creating circuit board B in the mounting operation following the next mounting operation as 7 8 mm

feeders

70a and 3 16 mm feeders 70b. The planned storage positions of the tape feeders 70 to be used when creating circuit board B are set to slots 17 to 30. The planned storage positions of the 8 mm feeders 70a to be used when creating circuit board B are set to slots 17 to 23, and the planned storage positions of the 16 mm feeders 70b are set to slots 25 to 30. For this reason, PC 130 lights up an LED 158 corresponding to any one of slots 17 to 23 as the planned storage position of the 8 mm feeder 70a to be used when creating circuit board B. The PC 130 also lights up an LED 158 corresponding to one of

slots

26, 28, and 30 among slots 25 to 30 as the intended storage position of the 16 mm feeder 70b used when creating the circuit board B. Note that

slots

5, 12, 16, and 24 are not set as intended storage positions because there is a risk of interference between tape feeders 70 of different widths being stored in adjacent slots 152.

In this way, the planned storage position of the tape feeder 70 is notified by the LED 158, so that the tape feeder 70 can be stored in a predetermined area of the feeder storage 150 according to the type of circuit board. In other words, the tape feeders 70 can be stored together for each type of circuit board. This allows the worker to take out the tape feeder 70 from a predetermined area of the feeder storage 150 during setup work, which saves the worker's time. In other words, for example, when the worker performs setup work for circuit board A, he or she only needs to take out the tape feeder 70 from the area of slots 1 to 15, which reduces the worker's movement range and saves the worker's time. In addition, the above method allows the tape feeder 70 to be stored in a predetermined area according to the width of the tape feeder 70. In other words, the tape feeders 70 can be stored together for each width of the tape feeder 70. This allows the tape feeders 70 to be stored in the feeder storage 150 without waste. That is, as described above, if tape feeders 70 of different widths are stored in adjacent slots 152, there is a risk that the tape feeders 70 will interfere with each other. Therefore, if the tape feeders 70 are stored randomly, there will be many empty slots to avoid interference between the tape feeders 70. However, by storing the tape feeders 70 together by their width, it is possible to reduce the number of empty slots between tape feeders of different widths. This makes it possible to store the tape feeders 70 in the feeder storage 150 without waste.

The PC 130 may also notify a slot located within a predetermined area according to the type of electronic component by lighting up the LED 158 as the slot of the planned storage position of the tape feeder 70. In more detail, for example, as shown in FIG. 10, the planned storage position of the tape feeder 70 of electronic component A is set to slots 1 to 10, the planned storage position of the tape feeder 70 of electronic component B is set to slots 11 to 20, and the planned storage position of the tape feeder 70 of electronic component C is set to slots 21 to 30. The PC 130 then lights up the LED 158 corresponding to any one of slots 1 to 10 based on the width information of the tape feeder 70 as the planned storage position of the tape feeder 70 of electronic component A. The PC 130 also lights up the LED 158 corresponding to any one of slots 11 to 20 based on the width information of the tape feeder 70 as the planned storage position of the tape feeder 70 of electronic component B. Furthermore, the PC 130 lights up an LED 158 corresponding to one of the slots 21-30 as the planned storage position of the tape feeder 70 for electronic component C based on the width information of the tape feeder 70. In this way, the planned storage position of the tape feeder 70 is notified by the LED 158, so that the tape feeder 70 can be stored in a predetermined area of the feeder storage 150 according to the type of electronic component. In other words, it is possible to store the tape feeders 70 together by type of electronic component. This allows the worker to remove the tape feeders 70 for the same type of electronic component from the predetermined area, saving the worker time.

The PC 130 may also notify the user by lighting up the LED 158 that a slot located on the lower shelf of the feeder storage 150 is the intended storage location for the 16 mm feeder 70b and the 24 mm feeder 70c. In other words, the PC 130 lights up the LED 158 that corresponds to one of the slots located on the lower shelf based on the width information of the tape feeder 70 as the intended storage location for the 16 mm feeder 70b and the 24 mm feeder 70c. On the other hand, the PC 130 lights up the LED 158 that corresponds to one of the slots located on the upper shelf based on the width information of the tape feeder 70 as the intended storage location for the 8 mm feeder 70a. In this way, the intended storage position of the tape feeder 70 is notified by the LED 158, so that a wide tape feeder 70, i.e., a heavy tape feeder 70, can be stored in the lower level of the feeder storage 150, and a narrow tape feeder 70, i.e., a light tape feeder 70, can be stored in the upper level of the feeder storage 150. This makes it possible to reduce the labor of the worker.

Note that the 8 mm feeder 70a is an example of a narrow feeder. The 16 mm feeder 70b and the 24 mm feeder 70c are examples of wide feeders. The connector 120 is an example of a connector. The feeder storage 150 is an example of a feeder storage. The slot 152 is an example of a slot. The connector connection portion 156 is an example of a connector connection portion. The LED 158 is an example of a lighting device.

Furthermore, the present invention is not limited to the above embodiment, and can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiment, as shown in FIG. 6, the PC 130 turns on the LED 158 of slot 2 of

slots

2, 4, and 5 as the intended storage position of the 8 mm feeder 70a, but as shown in FIG. 11, all of the LEDs 158 of

slots

2, 4, and 5 may be turned on. In other words, the PC 130 may turn on all of the LEDs 158 of

slots

2, 4, and 5 that can store the 8 mm feeder 70a as the intended storage position of the 8 mm feeder 70a.

In the above embodiment, as shown in FIG. 7, the PC 130 lights up the LED 158 of slot 5, which corresponds to the connector connection portion 156 to which the connector 120 of the 16 mm feeder 70b is connected, but as shown in FIG. 12, the PC 130 may light up the LEDs 158 of both

slots

4 and 5. In other words, the PC 130 may light up all the LEDs 158 of

slots

4 and 5 in which the feeder body 75 of the 16 mm feeder 70b is stored, as the intended storage position of the 16 mm feeder 70b.

In the above embodiment, the PC 130 lights up the LED 158 in the lower slot of the feeder storage 150 as the intended storage position of the wide tape feeder 70, but the LED 158 in the lower slot of the feeder storage 150 may also be turned on based on the weight of the tape feeder 70. Specifically, for example, information indicating the weight of the tape feeder 70 is stored in the PC 130, and the PC 130 determines whether the weight of the tape feeder 70 to be stored exceeds a threshold value based on that information. Then, if the weight of the tape feeder 70 to be stored exceeds the threshold value, the LED 158 in the lower slot of the feeder storage 150 may be turned on as the intended storage position of the tape feeder 70.

In addition, in the above embodiment, the planned storage position of the tape feeder 70 is indicated by the LED 158, but the planned storage positions of various feeders, such as stick feeders and bulk feeders, may also be indicated by the LED 158.

In addition, in the above embodiment, the intended storage position of the tape feeder 70 is indicated by the LED 158, but the intended storage position of the tape feeder 70 may be indicated by various methods, such as sound.
