Description

  The present invention relates to a component supply method for taking out and supplying the components from a plurality of component holders set on a component mounter for mounting the components on a substrate.

  2. Description of the Related Art Conventionally, there is a component mounting machine that takes out an electronic component from a component tape that stores a plurality of electronic components and mounts the electronic component on a substrate (see, for example, Patent Document 1).

  The component tape stores a plurality of electronic components of the same type, and is set in the component mounter by the number corresponding to the type of electronic components to be mounted on the board. A Z number is assigned to each set position where a plurality of component tapes are set.

  Such a component mounting machine of Patent Document 1 holds component arrangement data indicating an electronic component (master component) to be arranged for each Z number and a component that can be substituted for the electronic component (substitute component). Therefore, this component mounting machine detects the electronic component of the component tape actually set for each Z number before performing component mounting, and determines whether the electronic component is a master component or an alternative component. Judgment is made by referring to the component arrangement data.

If a master part or an alternative part is arranged at each Z number as a result of such determination, the component mounter takes out an electronic component from each component tape and mounts it on the board. That is, the component mounter supplies electronic components from each component tape. On the other hand, as a result of the determination, if a master part or a substitute part is not arranged at each Z number, the component mounter notifies an error and stops supplying electronic components from each component tape.
Japanese Patent No. 3509107

  However, the method of supplying electronic components by the component mounter of Patent Document 1 has a problem that it takes time to set component tapes.

  That is, in the component mounting machine of Patent Document 1 described above, if there is no master part or substitute part to be arranged at a predetermined Z number, an error is notified even if the master part or substitute part exists in another Z number. The master part or substitute part cannot be supplied. As a result, the worker has to re-arrange the master part or the substitute part at the other Z number to the predetermined Z number.

  Therefore, the present invention has been made in view of such problems, and an object of the present invention is to provide a component supply method that improves the usability by eliminating the trouble of setting a component on a component mounter.

In order to achieve the above object, a component supply method of the present invention is a component supply method in which the component is taken out and supplied from a plurality of component holders set in a component mounter for mounting the component on a board. Each of the component holders is provided with an IC (Integrated Circuit) tag storing identification information for identifying the component held by the component holder, and is further set in the component supply unit. Further, two IC tag readers for receiving signals from the IC tags are provided on both sides of the arrangement of the plurality of component holders, and the component supply method includes the IC attached to each component holder. Based on the direction of the signal received by the two IC tag readers from the tag, the position coordinates of each IC tag are acquired, and the respective position set in the component supply unit due to the difference in the position coordinates of the acquired IC tags. A position specifying step for specifying the set position of the article holder, a reading step for reading out the identification information from the IC tag having a position coordinate corresponding to the set position of the component holder specified in the position specifying step, Based on the identification information read in the reading step and each set position specified in the position specifying step, a set position where a component holder that holds a required component required for mounting on the board is set is searched. And a first supply step of taking out and supplying a component from the component holder at the set position when the set position searched in the first search step is found. Features.
The component supply method of the present invention is a component supply method for taking out and supplying the component from a plurality of component holders set on a component mounter for mounting the component on a board, wherein each of the component holders is provided. Is attached with an IC (Integrated Circuit) tag for storing identification information for identifying a component held by the component holder, and the component supply method includes setting each component holder. A position specifying step for specifying a set position, a reading step for reading identification information from an IC tag attached to each of the component holders, each identification information read in the reading step, and a position specifying step. A first search step for searching for a set position where a component holder for holding a required component required for mounting on the board is set based on each set position; and When the retrieved set position found in step is characterized in that it comprises a first supply step of supplying Remove the device from the component holder is in said set position.

  As a result, the set position where the component holder that holds the required component is set is retrieved, and the component is taken out and supplied from the component holder at the set position, so the worker holds the required component. The component holder may be set at any setting position of the component mounter, and the usability can be improved by eliminating the trouble of setting the component holder, that is, the component on the component mounter.

  The first search step may further include searching for a set position where a component holder that holds an alternative component that can replace the required component is set. For example, in the first search step, a set position of a component holder that holds the required component and a component holder that holds the alternative component by referring to specified component data indicating the required component and the alternative component Search for.

  Thereby, for example, when the set position of the required part is not found, the set position of the component holder that holds the substitute part is also retrieved and the substitute part is supplied. In spite of being set, it is possible to save the trouble of having to set the parts holder for the required part, and to further improve the usability.

  Here, in the component supply method, when the set position searched in the first search step is not found, a warning is issued for notifying that the component holder that holds the requested component is not set. It may be characterized by including steps.

  As a result, the operator can easily know from the warning that the necessary component holder is not set, and the production efficiency can be improved.

  The component supply method further includes a component remaining number determining step for determining whether or not a remaining number of components held by any of the component holders has reached a predetermined value, and a remaining component number determining step. When it is determined that the number has reached a predetermined value, a second search step of searching for a set position of another component holder that holds the same component as the component for which the remaining number has reached the predetermined value; When the set position searched in the search step is found, a second supply step may be included, in which a part is taken out and supplied from the part holder at the set position.

  Thus, for example, when the predetermined value is 0 and the remaining number of component holders is 0, that is, when the component holder is out of components, the set position of another component holder that holds the component is searched, Since components are supplied from other component holders, the operator can save time and effort to stop the component mounter and replace a component holder that has run out of components. As a result, usability can be further improved.

  Here, in the second search step, it is further possible to search for a set position where a component holder that holds a substitute component that can be substituted for the component whose remaining number is a predetermined value is set. good.

  Thereby, for example, when the set position of the same part as the part that has run out of parts is not found, the set position of the part holder that holds the substitute part is also retrieved, and the part is supplied from the part holder. Therefore, the operator can save the trouble of having to replace the component holder that has run out of the parts even though the component holder of the substitute part is set. As a result, usability can be further improved.

  In the reading step, the identification information may be read from an IC tag attached to each component holder via an antenna disposed in the vicinity of the IC tag.

Thereby, it is possible to reliably read the identification information from the IC tag.
Here, in the position specifying step, a set position of each component holder may be specified based on a signal output from an IC tag attached to the plurality of component holders.

  Thereby, for example, the set position of each component holder is specified based on the signal output such as the signal intensity and the output direction, so that the set position of the component holder can be easily specified.

  The present invention can be realized not only as such a component supply method, but also based on the component supply device that supplies components based on the method, the component mounter including the component supply device, and the method The present invention can also be realized as a program for executing a computer to supply parts and a storage medium for storing the program.

  The component supply method of the present invention has an effect that the usability can be improved by eliminating the time and effort required for setting the component on the component mounter.

  Hereinafter, a component mounting system according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an external view showing the overall configuration of a component mounting system 10 according to an embodiment of the present invention. The component mounting system 10 includes a plurality of component mounting machines 100 and 200 constituting a production line on which electronic components are mounted while sending a circuit board (board) 20 from upstream to downstream. Since the component mounters 100 and 200 have the same configuration, the component mounter 100 will be described in detail below.

  The component mounting machine 100 includes two sub facilities (a front sub facility 110 and a rear sub facility 120) that perform component mounting simultaneously and independently. Each sub-equipment 110 (120) is an orthogonal robot type mounting stage, which includes component supply units 115a and 115b, a multi-mounting head 112, an XY robot 113, a component recognition camera 116, a tray supply unit 117, and an IC tag reader. / The writer 111 etc. are provided. Each of the component supply units 115a and 115b includes an array of a maximum of 48 component cassettes 114 for storing component tapes. The multi-mounting head 112 is also referred to as a 10-nozzle head or simply a head, and 10 suction nozzles (hereinafter simply referred to as “nozzles”) that can pick up a maximum of 10 components from the component cassette 114 and mount them on the substrate 20. "). The XY robot 113 moves the multi mounting head 112. The component recognition camera 116 is used for two-dimensionally or three-dimensionally inspecting the suction state of the component sucked by the multi-mounting head 112. The tray supply unit 117 supplies tray parts. The IC tag reader / writer 111 reads information stored in the IC tag and writes information in the IC tag. The IC tag is attached to a supply reel on which a component tape is wound. Each such sub-equipment executes component mounting on the board in charge of each sub-equipment independently (in parallel) with the other sub-equipment.

  The “component tape” is actually a plurality of components of the same component type arranged on a tape (carrier tape) and supplied in a state of being wound around a reel (supply reel) or the like. The It is mainly used to supply a relatively small size component called a chip component to a component mounter. Note that a component supplied by a component tape is called a taping component.

  Specifically, the component mounting machine 100 is a mounting machine having both functions of a component mounting machine called a high-speed mounting machine and a component mounting machine called a multi-function mounting machine. A high-speed mounting machine is a facility characterized by high productivity that mainly mounts electronic parts of □ 10 mm or less at a speed of about 0.1 seconds per point. A multi-function mounting machine is a large model of □ 10 mm or more. It is equipment for mounting electronic parts, odd-shaped parts such as switches and connectors, and IC parts such as QFP (Quad Flat Package) and BGA (Ball Grid Array).

  In other words, the component mounting machine 100 is designed to be able to mount almost all kinds of electronic components (from 0.4 mm × 0.2 mm chip resistance to 200 mm connector as components to be mounted) A production line can be configured by arranging a required number of the component mounting machines 100.

FIG. 2 is a plan view showing a main configuration of the component mounter 100 according to the present invention.
The shuttle conveyor 118 is a moving table (component conveyor) for loading the components taken out from the tray supply unit 117 and transporting them to a predetermined position where the multi-mounting head 112 can suck them. The nozzle station 119 is a table on which replacement nozzles for accommodating various types of component types are placed.

  The two component supply units 115a and 115b constituting each sub-equipment 110 (or 120) are respectively arranged on the left and right with the component recognition camera 116 interposed therebetween. Therefore, the multi-mounting head 112 that has picked up the components in the component supply unit 115a or 115b moves to the mounting point of the board 20 after passing through the component recognition camera 116, and performs an operation of sequentially mounting all of the sucked components. repeat. “Mounting point” refers to a coordinate point on a board on which a component is to be mounted, and components of the same component type may be mounted at different mounting points. The total number of components (mounting points) arranged on the component tape relating to the same component type matches the number of components of that component type (total number of components to be mounted).

  Here, a single operation (suction / moving / mounting) in a repetition of a series of operations of sucking / moving / mounting components by the multi-mounting head 112, or a group of components mounted by such a single operation is expressed as “ Called “task”. For example, according to the 10 nozzle head 112, the maximum number of parts to be mounted by one task is 10. Here, “suction” includes all suction operations from when the head starts to pick up components until it moves. For example, 10 suction operations (up and down operation of the multi-mounted head 112). This includes not only the case of picking up these parts, but also the case of picking up 10 parts by a plurality of picking operations.

  Two IC tag readers / writers 111 are provided in each sub-equipment 110 (or 120). The IC tag reader / writer 111 transmits a radio wave having a predetermined frequency including a read command to the IC tag, and receives a radio wave having a predetermined frequency including information stored in the IC tag from the IC tag. The position of the IC tag is specified by the direction or intensity of the radio wave received by the IC tag reader / writer 111.

  FIG. 3 is a diagram showing a circuit configuration of the IC tag reader / writer 111 and a circuit configuration of the IC tag.

  The IC tag reader / writer 111 includes a modulation / demodulation unit 462 connected to an AC power source 461, a control unit 463, an interface unit 464, and an antenna 465.

  The modulation / demodulation unit 462 is a circuit that communicates with the IC tag 426b through the antenna 465. The modulation / demodulation unit 462 transmits power carrier waves to the IC tag 426b and receives component information transmitted from the IC tag 426b. That is, while the modulation / demodulation unit 462 receives the control code output from the control unit 463, the modulation / demodulation unit 462 generates a power carrier signal of a radio frequency (RF: Radio Frequency, for example, 13.56 MHz), and converts the signal into power It is converted into a carrier wave and transmitted from the antenna 465. In addition, the modulation / demodulation unit 462 transmits information on a component to be written to the IC tag 426b from the antenna 465.

  The control unit 463 controls transmission of the power carrier radio wave by the modulation / demodulation unit 462 and stop of the transmission, and outputs component information received by the modulation / demodulation unit 462 to the outside via the interface unit 464.

  The IC tag 426b includes an antenna 471, a modulation / demodulation unit 472, a power generation unit 473, and a logic memory 474. The logic memory 474 stores component information.

  The power generation unit 473 receives the power carrier radio wave transmitted from the IC tag reader / writer 111 via the antenna 471 by the electromagnetic induction method or the electromagnetic coupling method, and generates high-frequency induced power. The power generation unit 473 further rectifies the induced power, smoothes the voltage of the rectified induced power to a constant value, accumulates DC power, and the antenna 471 receives the power carrier radio wave. Meanwhile, the generated DC power is continuously supplied to the modulation / demodulation unit 472 and the logic memory 474.

  The modulation / demodulation unit 472 converts the component information stored in the logic memory 474 into a radio wave and outputs it to the outside via the antenna 471. As long as the modulation scheme matches the demodulation scheme in the modulation demodulator 462 of the IC tag reader / writer 111, an arbitrary scheme such as ASK (Amplitude Shift Keying) or FSK (Frequency-Shift Keying) can be used. it can. Further, the modulation / demodulation unit 472 demodulates the component information transmitted from the IC tag reader / writer 111 and writes it into the logic memory 474.

  FIG. 4 is a schematic diagram showing the positional relationship between the multi-mounting head 112 and the component cassette 114. The multi-mounting head 112 is a working head called “gang pickup system”, and can attach up to ten suction nozzles 112a to 112b. At this time, the parts from each of up to ten parts cassettes 114 can be attached. Can be adsorbed simultaneously (by a single up-and-down motion).

  Note that only one component tape is loaded into the component cassette 114 called “single cassette”, and two component tapes are loaded into the component cassette 114 called “double cassette”. In addition, the set position of the component cassette 114 (or component tape) in the component supply units 115a and 115b is referred to as “value on the Z axis” or “position on the Z axis (Z number)”. A serial number or the like whose left end is “Z1” is used. Accordingly, as an important procedure for determining the mounting order for taping components, the arrangement (position on the Z-axis) of the component type (or component tape or component cassette 114 storing the component tape) is determined. . The “Z-axis” refers to a coordinate axis that specifies an arrangement position (set position) of component cassettes set for each component mounter (or a sub-equipment when a sub-equipment is provided).

  FIG. 5 is an explanatory diagram for explaining the configuration of a total of four component supply units included in the component mounter 100.

  As shown in FIG. 5A, each of the component supply units 115a, 115b, 215a, and 215b can mount a maximum of 48 component tapes (each position (Z number) is Z1 ~ 1. Z48, Z49 to Z96, Z97 to Z144, Z145 to Z192). Specifically, as shown in FIG. 5B, a maximum of 48 types can be provided for each component supply unit (A block to D block) by using a double cassette containing two component tapes having a tape width of 8 mm. Can be mounted. The larger the tape width (component cassette), the smaller the number of cassettes that can be mounted in one block.

  It should be noted that the left part supply units 115a and 215a (A block, C block) toward each sub-equipment are “left block”, and the right part supply units 115b and 215b (B block and D block) toward each sub-equipment. Is also called “right block”.

  FIGS. 6A and 6B are a diagram and a table showing examples of the position (Z-axis) of the component supply unit that can be sucked by the 10 nozzle head. In addition, H1-H10 in a figure points out the nozzle (position) mounted in the 10 nozzle head.

  Here, the interval between the nozzles of the 10-nozzle head corresponds to the width (21.5 mm) of one double cassette, so the Z numbers of parts picked up by one up-and-down movement are every other number (only odd numbers) (Or even number only). In addition, due to the movement restriction of the 10 nozzle head in the Z-axis direction, as shown in FIG. 6B, the nozzle that cannot adsorb to the component (Z-axis) constituting one end of each component supply unit ("-" In the figure) exists.

Next, the detailed structure of the component cassette 114 will be described with reference to FIGS.
FIG. 7 is an external view showing an external appearance of an electronic component to be mounted. FIG. 8 is a diagram showing an example of a component tape containing electronic components and a supply reel.

  Various chip-type electronic components 423a to 423d as shown in FIGS. 7A to 7D are housed in a housing recess 424a formed continuously at a predetermined interval on the carrier tape 424 shown in FIG. A cover tape 425 is attached to the upper surface for packaging. The carrier tape 424 with the cover tape 425 attached in this way is supplied to the user in a taping form wound around the supply reel 426 by a predetermined quantity. However, the shape of the part in which the electronic component is stored is not limited to the concave shape. In addition, the carrier tape 424 and the cover tape 425 constitute a component tape, and the component tape and the supply reel 426 (or the component cassette 114 including these) function as a component holder that holds electronic components. To do.

  An IC tag 426b is attached to the supply reel 426, and component information is stored in the IC tag 426b. This part information includes part information, number of taping parts, manufacturer name, manufacturing factory name, manufacturing date and time, lot name, and other manufacturing information, part dimensions, width of the part cassette 114 to which the carrier tape 424 is attached, and a storage recess 424a. Information such as the pitch interval is included. In addition to the carrier tape 424 as shown in FIG. 8, there are also an adhesive tape in which components are adhesively fixed to the tape, a paper tape, and the like.

  FIG. 9 is a diagram illustrating an example of a component cassette 114 to which a component tape and a supply reel are attached.

  The component tape and the supply reel 426 for storing the electronic component 423d and the like as described above are used by being attached to the component cassette 114 as shown in FIG. The supply reel 426 is rotatably attached to a reel side plate 428 coupled to the main body frame 427. The carrier tape 424 drawn out from the supply reel 426 is guided to the feed roller 429. Then, the feed lever 430 of the component cassette 114 is moved by a feed lever (also not shown) provided in the electronic component automatic mounting device (not shown) on which the component cassette 114 is mounted. The ratchet 432 is rotated at a constant angle through the link 431 attached to the feed lever 430, moving in the direction of the arrow Y1 in the figure. The feed roller 429 interlocked with the ratchet 432 moves by a constant pitch (for example, a feed pitch of 2 mm or 4 mm). The carrier tape 424 may be sent out by motor driving or cylinder driving.

  Further, the carrier tape 424 is peeled off by the cover tape peeling portion 433 in front of the feed roller 429 (on the supply reel 426 side). The peeled cover tape 425 is taken up by the cover tape take-up reel 434, and the carrier tape 424 from which the cover tape 425 has been peeled off is conveyed to the electronic component take-out unit 435. A vacuum suction head (not shown) from the electronic component take-out portion 435 opened in conjunction with the ratchet 432 at the same time as the feed roller 429 transports the carrier tape 424, and the chip-type electronic housed in the housing recess 424a. The component 423d is sucked and taken out. Thereafter, the feed lever 430 is released from the pushing force by the feed lever and returns to the Y2 direction, that is, to the original position by the urging force of the tension spring 436.

  When the above series of operations is repeated, the used carrier tape 424 is configured to be discharged to the outside of the component cassette 114.

The operational characteristics of the component mounter 100 are summarized as follows.
(1) Nozzle replacement When the nozzle required for the next mounting operation is not in the multi mounting head 112, the multi mounting head 112 moves to the nozzle station 119 and performs nozzle replacement. As types of nozzles, there are, for example, types S, M, and L, depending on the size of the parts that can be picked up.
(2) Component adsorption The multi-mounting head 112 moves to the component supply units 115a and 115b and adsorbs electronic components. When 10 parts cannot be picked up at the same time, a maximum of 10 parts can be picked up by moving the picking position up and down several times.
(3) Recognition Scan The multi mounting head 112 moves on the component recognition camera 116 at a constant speed, captures images of all electronic components sucked by the multi mounting head 112, and accurately detects the suction position of the components.
(4) Component mounting Electronic components are sequentially mounted on the substrate 20.

  By repeating the operations (1) to (4), all electronic components are mounted on the substrate 20. The operations (2) to (4) are basic operations in mounting a component by the component mounter 100 and correspond to “tasks”. That is, a maximum of 10 electronic components can be mounted on the board in one task.

  Here, the characteristics of the component mounters 100 and 200 in the embodiment of the present invention will be described. Since the component mounters 100 and 200 have the same characteristics, the component mounter 100 will be mainly described.

  The component mounter 100 according to the present embodiment collates whether or not the component cassette 114 containing the component tape is correctly set in the component supply units 115a and 115b, and the desired component cassette 114 from the set component cassette 114. It has the feature of searching.

  That is, in the component mounter 100 according to the present embodiment, when there is no component cassette 114 having a component to be set at the predetermined Z number of the component supply units 115a and 115b, that component or a component that can be substituted for it. The Z number in which the parts cassette 114 having “” is set is searched. When mounting a component that should be at the predetermined Z number, the component mounter 100 takes out the component in the component cassette 114 at the searched Z number and mounts it.

  Also, in the component mounting machine 100 according to the present embodiment, when all the components are taken out from the component tape of the component cassette 114 at a predetermined Z number, the component cassette 114 having the component or a component that can be replaced by that component is set. Search for the current Z number. When the component mounter 100 tries to mount the already lost component, the component mounter 100 takes out the component from the component cassette 114 at the searched Z number and mounts it.

As shown in FIG. 13, the unit ID for identifying the sub-equipment, the multi-mounting head Head information regarding the type of nozzle, nozzle information regarding the type of suction nozzle that can be attached to the multi-mounting head, cassette information regarding the maximum number of component cassettes 114, etc., tray information regarding the number of trays stored in the tray supply unit 117, etc. Etc.

  FIG. 14 is a diagram illustrating an example of the component arrangement data stored in the component arrangement data storage unit 308.

  The component arrangement data 308a is data indicating taping components set along the Z axis in each sub-equipment 110, 120 for each Z number. That is, the component arrangement data 308a includes the component name of the taping component and the Z number of the component cassette 114 having the taping component for each unit ID for identifying the sub-equipment.

  Such component arrangement data 308 a is created by the arithmetic control unit 301 and stored in the component arrangement data storage unit 308. That is, the arithmetic control unit 301 creates the component arrangement data 308a by specifying the Z number of the component cassette 114 for each sub-equipment and acquiring the component information from the IC tag 426b of the component cassette 114 at the Z number. To do.

  Here, the identification of the Z number of the component cassette 114 includes a method using the IC tag reader / writer 111 and the IC tag 426b and a method using the switches provided in the component supply units 115a and 115b.

  FIG. 15 is a diagram for explaining a method of specifying the Z number of the component cassette 114 using the IC tag reader / writer 111 and the IC tag 426b.

  The two IC tag reader / writers 111 specify the position of each IC tag 426b based on the direction of radio waves received from each IC tag 426b. For example, the identification information is stored in each IC tag 426b, and the combination of the directions of radio waves received from the IC tag 426b in which the two IC tag reader / writers 111 hold the same identification information, the position of the IC tag 426b, Is created in advance, and the position of each IC tag 426b is specified in accordance with the table. As a specific method for specifying the direction of the received radio wave, the IC tag reader / writer 111 refers to the correspondence table between the received intensity and the direction previously associated with each other based on the intensity of the radio wave received from the IC tag 426b. Identify the direction of the received radio wave. Alternatively, by rotating the IC tag reader / writer 111 on a motor-driven turntable and rotating the receiving surface of the antenna 465, the direction of the received radio wave can be specified from the angle of the turntable that maximizes the reception intensity. Good.

  When the position of the IC tag 426b is specified in this way, the arithmetic control unit 301 specifies the Z number of the component cassette 114 from the position. For example, as shown in FIG. 15, when X increases by 10 and the Z number increases by one, the two IC tag reader / writers 111 are connected to the IC tag 426b attached to the component cassette 114 having the component A. Is specified as (X, Y) = (10, 4). As a result, the arithmetic control unit 301 specifies that the Z number of the component cassette 114 having the component A is 1 from the X coordinate. In the case of a double cassette, two component tapes exist for the same Z number. However, since the X coordinate of the IC tag 426b attached to the supply reel 426 of each component tape is different, the arithmetic control unit 301 can determine whether the component tape is located on the left side or the right side of the double cassette.

  Further, the two IC tag reader / writers 111 receive component information including a component name from each IC tag 426b and notify the arithmetic control unit 301 of the component information. As a result, the arithmetic control unit 301 specifies the component information about the components included in the component cassette 114 and the Z number of the component cassette 114, and creates the component arrangement data 308a based on these.

  Note that the method of specifying the position of the IC tag 426b is not limited to the direction of radio waves, and may be based on the strength of radio waves received by the two IC tag reader / writers 111 or the ratio of the strengths of radio waves. . Further, when the IC tag 426b outputs a signal using electromagnetic waves, infrared rays, or the like as a wireless communication medium, the position of the IC tag 426b may be specified based on the signal output such as the intensity and direction.

  The number of IC tag readers / writers 111 is not necessarily two, and may be one as long as the position of the IC tag 426b can be determined from the strength and direction of the received radio wave.

  FIG. 16 is an explanatory diagram for explaining how one IC tag reader / writer 111 specifies the position of the IC tag 426b.

  For example, the component mounting machine 100 includes one IC tag reader / writer 111 and an antenna 111a disposed from the IC tag reader / writer 111 to the vicinity of the IC tag 426b of each component cassette 114 in the component supply units 115a and 115b. Is provided.

  As described above, since the antenna 111a is close to each IC tag 426b, the IC tag reader / writer 111 can surely obtain component information from each IC tag 426b even if the IC tag reader / writer 111 is away from each IC tag 426b. . Further, the IC tag reader / writer 111 identifies the position of each IC tag 426b based on the output signal (for example, the intensity or direction of radio waves) of each IC tag 426b.

  Further, a plurality of antennas that can be switched for each IC tag 426b may be installed up to the vicinity of the corresponding IC tag 426b. In this case, since each antenna corresponds to each Z number (Z1, Z2,...), The IC tag reader / writer 111 switches the antenna output to obtain the switched antenna. The Z number of the corresponding IC tag 426b (component cassette 114) is specified, and the component information is acquired from the IC tag 426b.

  That is, each antenna is provided with a switch. When the switch is turned on, an output from the antenna corresponding to the switch is acquired by the IC tag reader / writer 111. For example, the IC tag reader / writer 111 turns on only the antenna switch corresponding to the Z number “Z1” from the switches corresponding to each antenna, and then turns on only the antenna switch corresponding to the Z number “Z2”. By turning on each switch in order so that it is turned on, the output of each antenna is switched and acquired.

  FIG. 17 is a diagram for explaining a method of specifying the Z number of the component cassette 114 using the switches provided in the component supply units 115a and 115b.

  One switch 450 is provided for each Z number of the component supply units 115a and 115b.

  Such a switch 450 is a switch that is electrically turned on when the component cassette 114 is set in the component supply unit 115a (115b). The arithmetic control unit 301 identifies the Z number of the component cassette 114 based on the output from each switch 450.

  FIG. 18 is a diagram illustrating an example of the prescribed array data stored in the prescribed array data storage unit 305.

  The specified array data 305a indicates, for each of the sub-equipment 110, 120, a master part that should be mainly set at each position (each Z number) on the Z-axis, or an alternative part that replaces the master part. The master part and the substitute part are taping parts, and the master part is a required part required for mounting on the board. When the arithmetic control unit 301 tries to mount a part having a predetermined part name on the board, the part having the predetermined part or its substitute part based on the Z number and the part name indicated in the specified array data 305a. The Z number of the cassette 114 is specified. In general, the arithmetic control unit 301 moves the nozzle 112a of the head 112 to the component cassette 114 at the Z number, and takes out the component from the component cassette 114.

  Such specified array data 305a includes a Z number, a part name of the master part, a part name of the alternative part A, and a part name of the alternative part B for each unit ID for identifying the sub-equipment.

  For example, the specified array data 305a for the front sub-equipment 110 (unit ID 110) shown in FIG. 18 includes a Z number “Z1”, a master part “Pm1”, an alternative part A “Pa1”, and an alternative part B “Pb1”. Are shown in association with each other. Therefore, the specified array data 305a indicates that the component cassette 114 having the master component “Pm1” must be set in the Z number “Z1”. In addition, the specified arrangement data 305a sets the component cassette 114 having the substitute component A “Pa1” or the substitute component B “Pb1” in the Z number “Z1” instead of the component cassette 114 having the master component “Pm1”. Indicates that you can do it.

  FIG. 19 is a diagram illustrating an example of replacement data stored in the replacement data storage unit 309.

  The replacement data 309a indicates another Z number in which the Z number indicated in the specified array data 305a is replaced for each of the sub-equipment 110 and 120. For example, the replacement data 309a of the previous sub-equipment 110 (unit ID 110) is that the Z number “Z4” indicated in the prescribed array data 305a has been replaced with “Z5”, and the Z number “Z5” indicated in the prescribed array data 305a. Is replaced with “Z4”.

  For example, when the arithmetic control unit 301 attempts to mount a part having a predetermined part name on the board in the front sub-equipment 110, the Z number and part name indicated in the specified array data 305a of the front sub-equipment 110 (unit ID 110) Based on the above, the Z number of the component cassette 114 having the predetermined component or the replacement component is specified. Further, the arithmetic control unit 301 confirms whether or not the Z number has been replaced with another Z number with the replacement data 309a of the previous sub-equipment 110. As a result, if it has been replaced with another Z number, the arithmetic control unit 301 moves the nozzle 112a of the head 112 to the component cassette 114 at the replaced Z number, and takes out the component from the component cassette 114. Make it.

  Further, such replacement data 309a is created by the arithmetic control unit 301 based on the component arrangement data 308a and the prescribed arrangement data 305a and stored in the replacement data storage unit 309.

  FIG. 20 is an explanatory diagram for explaining a method of creating the replacement data 309a of the front sub-equipment 110.

  The arithmetic control unit 301 collates, for each Z number, the correct part indicated in the specified array data 305a of the front sub-equipment 110 and the part indicated in the part array data 308a of the front sub-equipment 110 (unit ID 110). If the part is an incorrect part, or if the part is not set, the Z number in which the correct part is set is searched from the part arrangement data 308a. If there is a Z number corresponding to the search result, the arithmetic control unit 301 creates replacement data 309a indicating that the Z number indicated in the specified array data 305a is replaced with the Z number corresponding to the search result.

  Specifically, the arithmetic control unit 301 first compares the component arrangement data 308a of the front sub-equipment 110 with the specified arrangement data 305a of the front sub-equipment 110, so that the component set to each Z number It is verified whether the master part, the alternative part A, or the alternative part B to be set to the Z number.

  For example, the arithmetic control unit 301 sets the master part “Pm1”, the substitute part A “Pa1”, or the substitute part B “Pb1” to the Z number “Z1” based on the specified array data 305 a of the front sub-equipment 110. Recognize that it must be. The arithmetic control unit 301 identifies the part “Pm1” set in the Z number “Z1” based on the part arrangement data 308a of the front sub-equipment 110, and identifies the part “Pm1” and the master part previously recognized. The alternative part A and the alternative part B are collated. As a result, the arithmetic control unit 301 determines that the previously recognized master part “Pm1” is set in the Z number “Z1”, that is, the correct part is set.

  Next, as described above, the arithmetic control unit 301 determines that the Z number “Z2” is the master part “Pm2”, the alternative part A “Pa2”, or the alternative part B “ Recognize that “Pb2” must be set. The arithmetic control unit 301 identifies the part “Pa2” set in the Z number “Z2” based on the part arrangement data 308a of the front sub-equipment 110, and identifies the part “Pa2” and the master part previously recognized. The alternative part A and the alternative part B are collated. As a result, the arithmetic control unit 301 sets the recognized alternative part A “Pa2” to the Z number “Z2”, that is, the correct part that is not a master part but can be substituted for it is set. Judge.

  If it is determined that the wrong part is set as a result of the collation, the arithmetic control unit 301 searches the part arrangement data 308a for the Z number where the correct part is set.

  For example, similarly to the above, the arithmetic control unit 301 should not set the master part “Pm4” or the alternative part A “Pa4” to the Z number “Z4” based on the specified array data 305a of the front sub-equipment 110. Recognize that it will not be. The arithmetic control unit 301 identifies the part “Pm5” set in the Z number “Z4” based on the part arrangement data 308a of the front sub-equipment 110, and identifies the part “Pm5” and the master part previously recognized. And the alternative part A are collated. As a result, the arithmetic control unit 301 determines that neither the master component recognized previously nor the substitute component A is set in the Z number “Z4”, that is, an incorrect component is set.

  Here, the arithmetic control unit 301 searches for the Z number in which the previously recognized master part “Pm4” or the alternative part A “Pa4” is set. For example, the arithmetic control unit 301 preferentially searches for a master part. As a result of the search, the arithmetic control unit 301 finds the Z number “Z5”. Then, the arithmetic control unit 301 determines that the Z number “Z4” indicated in the prescribed array data 305a should be replaced with “Z5”, and the replacement data of the previous sub-equipment 110 so that the content of the replacement is included. 309a is generated.

  Such a search for the Z number is performed not only when it is determined that an incorrect part is set as a result of collation as described above, but also when no part is set.

  For example, the arithmetic control unit 301 recognizes that the master part “Pm6” or the alternative part A “Pa6” must be set to the Z number “Z6” based on the specified array data 305a as described above. . Furthermore, the arithmetic control unit 301 recognizes that no component is set in the Z number “Z6” based on the component arrangement data 308a.

  Here, the arithmetic control unit 301 searches for the Z number in which the previously recognized master part “Pm6” or the alternative part A “Pa6” is set. As a result of the search, the arithmetic control unit 301 finds the Z number “Z7”. Then, the arithmetic control unit 301 determines that the Z number “Z6” indicated in the specified array data 305a should be replaced with “Z7”, and the replacement data of the previous sub-equipment 110 is included so that the content of the replacement is included. 309a is generated.

  Further, when the arithmetic control unit 301 in the present embodiment recognizes that the component in the component cassette 114 has disappeared due to the mounting of the component on the board (the component has run out), the Z number in which the component or an alternative component of the component is set. Search for. Then, based on the search result, the arithmetic control unit 301 updates the replacement data 309a of the previous sub-equipment 110. Here, the recognition of out of parts is performed based on the number of parts indicated by the part information and the number of parts actually used for component mounting. That is, the arithmetic control unit 301 acquires part information from the IC tag 426b corresponding to each Z-numbered part cassette 114 when creating the part array data 308a, and is included in each part cassette 114 from the part information. The number of parts is specified. Each time a component is taken out from the component cassette 114 for mounting, the arithmetic control unit 301 grasps the remaining number of the component cassette 114 by subtracting 1 from the previously specified number. Accordingly, the arithmetic control unit 301 recognizes that the parts cassette 114 is out of component when the remaining number becomes zero.

  For example, when the arithmetic control unit 301 recognizes that the parts cassette 114 set to the Z number “Z1” has run out, the part to be set to the Z number “Z1” is set to any other Z number. To find out. That is, the arithmetic control unit 301 searches the component arrangement data 308a for the Z number in which the master component “Pm1”, the alternative component A “Pa1”, and the alternative component B “Pb1” are set. As a result of the search, the arithmetic control unit 301 finds the Z number “Z (k + 1)”. Then, the arithmetic control unit 301 determines that the Z number “Z1” indicated in the specified array data 305a of the previous sub-equipment 110 should be replaced with “Z (k + 1)”, and the contents of the replacement are included. The replacement data 309a of the previous sub-equipment 110 is updated.

  FIG. 21 is a flowchart illustrating an operation in which the arithmetic control unit 301 creates the replacement data 309a for the front sub-equipment 110.

  First, the arithmetic control unit 301 sets the Z of each component cassette 114 set in the front sub-equipment 110 of the component mounter 100 based on communication between the IC tag reader / writer 111 and the IC tag 426b or on / off of the switch 450. A number is specified (step S100).

  Further, the arithmetic control unit 301 causes the IC tag reader / writer 111 to read the component information from the IC tag 426b attached to each component cassette 114 for which the Z number is specified (step S102).

  As a result, the arithmetic control unit 301 creates the component array data 308a of the previous sub-equipment 110 based on the Z number specified in step S100 and the component information read in step S102, and the component array data 308a is stored in the component arrangement data storage unit 308 (step S104).

  Next, the arithmetic control unit 301 determines each Z number based on the component array data 308a created in step S104 and the specified array data 305a of the previous sub-equipment 110 stored in the specified array data storage unit 305 in advance. Next, the replacement data 309a of the previous sub-equipment 110 is created by repeatedly executing the following steps S106 to S116 (steps S106 to S116).

  Specifically, the arithmetic control unit 301 determines whether or not the component of the component cassette 114 set to the Z number “Z1” is a master component (step S106). As a result, if it is not a master part (NO in step S106), the arithmetic control unit 301 determines whether or not the part in the part cassette 114 is a substitute part (step S108). As a result, if it is not a substitute part (NO in step S108), the arithmetic control unit 301 searches for the Z number in which the master part to be set to the Z number “Z1” or the part cassette 114 of the substitute part is set. (Step S110).

  As a result of the search, for example, if the Z number “Zx” is found (YES in step S112), the arithmetic control unit 301 creates replacement data 309a indicating that “Z1” in the specified array data 305a should be replaced with “Zx”. (Step S114).

  On the other hand, if the Z number is not found as a result of the search (NO in step S112), the arithmetic control unit 301 notifies the error by controlling the display unit 302 and the like (step S116).

  The arithmetic control unit 301 repeats the operations from step S106 to S116 as described above from the Z number “Z1” to “Zk” indicated in the prescribed array data 305a, and when step S114 is repeatedly executed, a new replacement is performed. The contents are included in the already created replacement data 309a, and the replacement data 309a is updated.

  When the above-described operation is performed up to the Z number “Zk”, the arithmetic control unit 301 stores the created replacement data 309a of the previous sub-equipment 110 in the replacement data storage unit 309 (step S118).

  The replacement data 309a for the rear sub-equipment 120 (unit ID 120) is also generated in the same manner as the replacement data 309a for the front sub-equipment 110.

FIG. 22 is a flowchart illustrating an operation in which the arithmetic control unit 301 recognizes that a part is out.
First, the arithmetic control unit 301 determines whether or not the head 112 has taken out one component from any of the component cassettes 114 and mounted (mounted) the substrate 20 (step S200).

  If the arithmetic control unit 301 determines that it is mounted (YES in step S200), it subtracts 1 from the remaining number of parts contained in the part cassette 114, and recognizes the subtraction result as a new remaining number (step S202). ). Here, when no component is taken out from the component cassette 114, the arithmetic control unit 301 refers to the component information already acquired from the IC tag 426b attached to the component cassette 114, and The number shown in the part information is recognized as the initial value of the remaining number. Whenever it is determined in step S200 that one component has been taken out, the arithmetic control unit 301 performs the operation in step S202 and updates the recognized remaining number.

  Next, the arithmetic control unit 301 determines whether or not the remaining number of parts is less than a predetermined threshold value (step S204). Here, when it is determined that the value is smaller than the threshold value (YES in step S204), the arithmetic control unit 301 issues a warning by controlling the display unit 302 and the like (step S206). When it is determined that the value is equal to or greater than the threshold value (NO in step S204), the arithmetic control unit 301 repeatedly executes the operation from step S200.

  After the warning in step S206, the arithmetic control unit 301 further determines whether or not the remaining number of parts is 0, that is, whether or not the parts have run out (step S208). Here, when it is determined that the component is out (YES in step S208), the arithmetic control unit 301 specifies the Z number of the component cassette 114 in which the component is out (step S210). On the other hand, when it is determined that the part is not out of stock (NO in step S208), the arithmetic control unit 301 repeatedly executes the operation from step S200.

  FIG. 23 is a flowchart showing an operation in which the arithmetic control unit 301 updates the replacement data 309a when a part is out.

  Based on the Z number of the component cassette 114 that has run out of parts and the specified array data 305a, the arithmetic control unit 301 specifies a master part and an alternative part to be set to the Z number (step S300).

  Next, the arithmetic control unit 301 determines whether or not the component cassette 114 having the master component or the substitute component is set in the component mounter 100 based on the component arrangement data 308a (step S302). That is, the arithmetic control unit 301 includes the master part or the substitute part associated with the Z number other than the Z number of the part cassette 114 that is out of parts in the part arrangement data 308a of the sub-equipment having the part cassette 114. It is determined whether or not.

  If it is determined that the component cassette 114 having the master component or the substitute component is set (YES in step S302), the arithmetic control unit 301 specifies the Z number of the component cassette 114 based on the component arrangement data 308a. (Step S304). That is, the arithmetic control unit 301 searches for the Z number of the component cassette 114 having the master component or the substitute component in steps S302 and S304. Then, the arithmetic control unit 301 updates the replacement data 309a so as to indicate that the Z number that has run out of parts is replaced with the Z number (the Z number specified in step S304) (step S306). On the other hand, if it is determined that the component cassette 114 having the master component or the substitute component is not set (NO in step S302), the arithmetic control unit 301 notifies the error by controlling the display unit 302 and the like (step S308). ).

  The overall operation of the component mounter 100 in this embodiment will be described with reference to FIG.

FIG. 24 is a flowchart showing the overall operation of the component mounting machine 100.
First, the arithmetic control unit 301 identifies the Z number of each component cassette 114 set in the component mounter 100 based on communication between the IC tag reader / writer 111 and the IC tag 426b (step S400). Further, the arithmetic control unit 301 causes the IC tag reader / writer 111 to read the component information from the IC tag 426b attached to each component cassette 114 for which the Z number is specified (step S402). As a result, the arithmetic control unit 301 creates component arrangement data 308a based on the Z number specified in step S400 and the component information read in step S402 (step S404). Then, the arithmetic control unit 301 searches for the Z number based on the component array data 308a created in step S404 and the specified array data 305a stored in the specified array data storage unit 305 in advance, thereby replacing the replacement data. 309a is created (step S406).

  Next, the arithmetic control unit 301 of the component mounter 100 determines the Z number of the component cassette 114 having the component to be mounted based on the component type Ci and the specified array data 305a which are component names indicated in the mounting point data 307a. Is identified (step S408).

  The arithmetic control unit 301 determines whether or not the Z number specified in step S408 is replaced with another Z number based on the replacement data 309a (step S410).

  When it is determined that it has been replaced in step S410 (YES in step S410), the arithmetic control unit 301 specifies the replaced Z number from the replacement data 309a (step S412).

  If the arithmetic control unit 301 determines in step S410 that the Z number has not been replaced (NO in step S410), the arithmetic control unit 301 moves the nozzle 112a of the head 112 to the component cassette 114 at the Z number to move from the component cassette 114. Let the parts be removed. When the replaced Z number is specified in step S412, the arithmetic control unit 301 moves the nozzle 112a of the head 112 to the component cassette 114 at the replaced Z number and takes out the component from the component cassette 114. Then, the component is supplied onto the substrate (step S414).

  The arithmetic control unit 301 controls the head 112 to mount the component supplied on the board in step S414 to the mounting point on the board indicated by the mounting point data 307a (step S416).

  As described above, in the component supply method performed by the component mounter 100 according to the present embodiment, the Z number in which the component cassette 114 holding the master component and the substitute component is set is searched, and the component cassette 114 at the Z number is searched. Since the components are taken out and supplied, the operator may set the component cassette 114 holding the master component or the substitute component at any Z number of the component mounting machine 100. The component mounting machine 100 of the component cassette 114 It is possible to improve the usability by omitting the time and effort required for setting.

Furthermore, in the component supply method performed by the component mounter 100 according to the present embodiment, when the component cassette 114 is out of components, the Z number of the other component cassette 114 that holds the component is retrieved, and the other component cassettes 114 are searched. Since the components are supplied, the operator can bother to stop the component mounter 100 and replace the component cassette 114 that has run out of components. As a result, usability can be further improved.
(Modification 1)
Here, the 1st modification regarding the attachment method of IC tag 426b of the said embodiment is demonstrated.

  In the above embodiment, the IC tag 426b is attached to the supply reel 426. However, the IC tag 426b according to this modification is attached to a tray, a bulk, a stick, or the like that holds a group of electronic components 423a to 423d.

FIG. 25 is a diagram illustrating a state where the IC tag 426b is attached to the tray.
The tray 117a supports the group of electronic components 423a to 423d so that they are arranged on a plane. A plurality of such trays 117a are accommodated in the tray supply section 117 so as to overlap each other with a gap therebetween.

  The IC tag 426b is attached to each tray 117a. The arithmetic control unit 301 of the component mounter 100 acquires component information from the IC tag 426b attached to the tray 117a for each position of each tray 117a using the two IC tag reader / writers 111, the antenna 111a, and the like. . The position of the tray 117a is a position in the arrangement direction of the trays 117a.

FIG. 26 is a diagram illustrating a state where the IC tag 426b is attached to the stick.
The stick 117b is an elongated container made of, for example, a resin molded product, and stores a group of electronic components 423a to 423d so that they are arranged in a line without any gap. A plurality of such sticks 117b are attached to the component mounter 100 in a line in such a manner that their longitudinal directions are along the vertical direction.

  The IC tag 426b is attached to each stick 117b. The component mounter 100 acquires component information from the IC tag 426b attached to the stick 117b for each position of each stick 117b using the two IC tag reader / writers 111, the antenna 111a, and the like. The position of the stick 117b is a position in the arrangement direction of the sticks 117b.

Further, as long as it is a component holder that holds a group of electronic components, the IC tag 426b may be attached to the component cassette (feeder) 114 in addition to a stick, a bulk (bulk cassette), a tray, a component tape, a reel, or the like.
(Modification 2)
Here, the 2nd modification regarding the data format of the regular arrangement | sequence data in the said embodiment is demonstrated.

  The specified array data 305a of the above embodiment indicates the Z number, the master part, the alternative part A, and the alternative part B. However, the specified array data according to this modification shows only the Z number and the master part.

  FIG. 27 is an explanatory diagram for explaining data stored in the defined array data storage unit 305 according to the present modification.

  The prescribed array data storage unit 305 according to this modification stores prescribed array data 305b and corresponding component data 305c.

  As shown in FIG. 27A, the specified array data 305b indicates only master parts that should be set mainly for each Z number for each of the sub-equipment 110, 120. For example, the specified array data 305b of the front sub-equipment 110 (unit ID 110) indicates that the master part “Pm1” should be set in the Z number “Z1”, and the master part “Pm2” in the Z number “Z2”. Indicates that should be set. That is, the specified array data 305b is obtained by deleting the contents related to the substitute parts from the specified array data 305a of the above embodiment.

  As shown in FIG. 27B, the corresponding part data 305c indicates each master part, and alternative parts A and B that can be replaced with the master part. For example, the corresponding part data 305c is associated with the master part “Pm1”, the alternative part A “Pa1” and the alternative part B “Pb1” that can be replaced with the master part “Pm1”. Similarly, the corresponding part data 305c indicates the master part “Pm2”, the alternative part A “Pa2” and the alternative part B “Pb2” that can be replaced with each other.

  That is, the specified array data 305b and the corresponding component data 305c each indicate the contents included in the specified array data 305a of the above embodiment. Further, the specified array data 305b and the corresponding component data 305c are stored in the specified array data storage unit 305 independently of each other, but are handled in the same manner as the specified array data 305a in the above embodiment.

  For example, when creating the replacement data 309a, the arithmetic control unit 301 according to the present modification uses the specified array data 305b and the corresponding component data 305c instead of the specified array data 305a. That is, the arithmetic control unit 301 collates, for each Z number, the master part indicated in the specified array data 305b and the part indicated in the part array data 308a. If the result of the collation is that they do not match, the arithmetic control unit 301 identifies the alternative part A or the alternative part B that can be replaced with the master part from the corresponding part data 305c, The above components shown in the component arrangement data 308a are collated. If there is still a mismatch in the collation, the arithmetic control unit 301 searches the component arrangement data 308a for the Z number of the component cassette 114 having any one of the master component, the substitute component A, and the substitute component B. If the Z number is found, the arithmetic control unit 301 creates replacement data 309a indicating that the Z number of the prescribed array data 305b is replaced with the found Z number.

Note that such corresponding component data 305c may be common to each of the sub-equipment 110 and 120, or may be different for each sub-equipment.
(Modification 3)
Here, the 3rd modification in the said embodiment is demonstrated. In the present embodiment, the replacement data 309a and the specified array data 305a are held. However, in this modified example, instead of these data, a component group indicating a plurality of components (component group) that can be replaced with each other. Retain data.

FIG. 28 is a diagram illustrating the contents of the above-described component group data.
For example, as shown in FIG. 28, the parts group data 305d indicates that the parts “Pm1”, “Pa1”, “Pb1” of the parts group “1” can be replaced with each other and can be mounted, and the parts group “2”. The parts “Pm2”, “Pa2”, and “Pb2” are shown as parts that can be exchanged with each other.

  That is, the parts group data 305d according to the present modification distinguishes the master part, the substitute part A, and the substitute part B that are respectively associated in the corresponding part data 305c of the above-described modification 1 as the master part and the substitute part. Instead, they are shown as parts that can be exchanged with each other.

  Here, the operation of the arithmetic control unit 301 of this modification using such component group data 305d will be described.

  First, the arithmetic control unit 301 determines, for each part group in the part group data 305d, whether or not a part cassette 114 having any part included in the part group is set based on the part arrangement data 308a. Determine.

  If the component cassette 114 having components (components “Pm1”, “Pa1”, “Pb1”) included in any component group (for example, component group “1”) is not set as a result of the determination, the component mounter 100 notifies an error. On the other hand, if the component cassettes 114 corresponding to all the component groups are set, the calculation control unit 301 recognizes the component required for mounting on the board based on the mounting point data 307a, for example, The Z number of the component cassette 114 having other components included in the same component group as that component is searched from the component arrangement data 308a. Then, the arithmetic control unit 301 controls the head 112 so as to take out components from the component cassette 114 and mount them on the board.

  Further, when the component cassettes 114 corresponding to all the component groups are set, the arithmetic control unit 301 may optimize the arrangement of the component cassettes 114. This optimization is to determine the arrangement of the component cassettes 114 so that the production time per substrate of the component mounting machine 100 is minimized. By performing such optimization, the operator arranges the arrangement of the component cassettes 114 in accordance with the arrangement determined by the optimization. Also in such a case, when the arithmetic control unit 301 recognizes the component cassette 114 that has run out of parts, the component that has run out of the parts, or a part having another part that is included in the same part group as the part. The Z number of the cassette 114 is searched, and the part is taken out from the part cassette 114.

  Thus, in this modification, it is not necessary to distinguish between the master part and the substitute part, and the data content held by the component mounter 100 can be simplified. As a result, the time required for creating the data can be shortened.

  As described above, the present invention has been described using the embodiment and the modified examples, but the present invention is not limited thereto.

  For example, in the embodiment and the modification, the component mounting machines 100 and 200 are described as modular machines. However, the component mounting machines 100 and 200 include other types of component mounting machines, for example, mounting heads having a rotation mechanism. It may be a rotary machine capable of mounting electronic components at high speed.

  In the embodiment and the modification, the replacement data 309a is generated and further updated. However, the replacement data 309a may not be generated. In this case, the arithmetic control unit 301 directly rewrites the Z number indicated in the prescribed array data 305a.

  Furthermore, in the present embodiment and the modification, the component arrangement data 308a is created, but the component arrangement data 308a need not be created. That is, each time the component mounter 100 collates the components or searches for the Z number, the component mounter 100 specifies the Z number of each component cassette 114 and reads the component information from the IC tag 426b that the component cassette 114 has.

  Further, in the present embodiment and modification, the IC tag 426b is attached to the supply reel 426. However, any component other than the IC tag 426b may be used as long as it stores component information and outputs the component information to the component mounter 100. Other storage media may be attached to the supply reel 426.

  The component supply method of the present invention is advantageous in that it is possible to improve the usability by omitting the time and effort required to set a component on a component mounter. For example, component mounting for mounting the electronic component while checking the electronic component It can be applied to machines.
