Description

[Technical field]

[0001] The present invention relates to a component mounting system, a replenished parts checking device, and a replenished parts checking method for checking whether or not parts to be replenished in a component supply unit are appropriate. [Background technology]

[0002] A component mounting device mounts components supplied from a component supply unit onto a board to manufacture a mounted board. When the number of components held by the component supply unit becomes low during the process of continuing component mounting, the component supply unit is replenished with components. Meanwhile, generic components that are generically mounted onto multiple types of boards may be supplied by multiple component manufacturers and have approximately the same shape and electrical characteristics. A mounted board manufacturing factory may purchase and store generic components of the same type from multiple component manufacturers and use them to manufacture mounted boards by switching between them as appropriate depending on the number of components in stock (see, for example, Patent Document 1).

[0003] Patent Document 1 describes how information relating each part to the name of a replaceable part is prepared in advance, and the part name in the mounting program is automatically changed based on the number of parts used and the number in stock, making it easy to change to an alternative part when replenishing a part supply unit.

[0004] [Patent Document 1] JP 2007-311546 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, even if parts have the same shape and electrical characteristics, there are parts with different guaranteed accuracy (tolerance) of the electrical characteristics. Therefore, parts that can withstand low accuracy of electrical characteristics can be replaced with alternative parts with high accuracy if the electrical characteristics are the same, but conversely, parts that require high accuracy may not be replaced with alternative parts with low accuracy. For example, in the case of two resistors that have the same resistance value but different resistance value accuracy (resistance value tolerance), a resistor with low resistance value accuracy may be replaced with a resistor with high resistance value accuracy, but the reverse may not be possible. However, in the conventional technology including Patent Document 1, parts specified in the information of replaceable parts are mutually replaced. Therefore, there is room for further improvement in order to enable replacement of parts corresponding to complex conditions as described above and to enable confirmation of the suitability of refill parts during part refill work.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a component mounting system, a replenished parts checking device, and a replenished parts checking method that can check whether the parts replenished to a component supply unit are appropriate. [Means for solving the problem]

[0007] The component mounting system of the present invention is a component mounting system that removes components set in a plurality of component supply units and mounts them at component mounting positions on a board, and includes a component mounting work unit that removes components from the plurality of component supply units and mounts them at the component mounting positions, a memory unit that stores alternative part information where a higher-level part can be used as a substitute for a lower-level part but the lower-level part cannot be used as a substitute for the higher-level part, a replenishment part information acquisition unit that acquires information on parts to be replenished to a component supply unit that is a target for component replenishment (hereinafter referred to as a replenishment target component supply unit), and a replenishment part confirmation unit that determines whether or not the part can be replenished to the replenishment target component supply unit based on the alternative part information and the part information acquired by the replenishment part information acquisition unit, and the replenishment part confirmation unit determines that the part to be replenished to the replenishment target component supply unit, in which the lower-level part is designated as a designated part, is capable of being replenished if the condition is met that the part is not the same as the designated part but is the higher-level part, and determines that the part cannot be replenished if the condition is not met.

[0008] The replenishment parts confirmation device of the present invention is a replenishment parts confirmation device that confirms parts to be replenished to a component supply unit of a component mounting device that removes parts set in the component supply unit and mounts them at component mounting positions on a board, and is equipped with a first information acquisition unit that acquires, from a memory unit, substitute part information where a higher-level part can be used as a substitute for a lower-level part, but the lower-level part cannot be used as a substitute for the higher-level part, a replenishment parts information acquisition unit that acquires information on parts to be replenished to a component supply unit that is to be replenished (hereinafter referred to as a replenishment target part supply unit), and a replenishment parts confirmation unit that determines whether or not the part can be replenished to the replenishment target part supply unit based on the substitute part information and part information acquired by the replenishment parts information acquisition unit, and the replenishment parts confirmation unit determines that the part to be replenished to the replenishment target part supply unit, in which the lower-level part is designated as a designated part, can be replenished if the condition is met that the part is not the same as the designated part but is the higher-level part, and determines that the part cannot be replenished if the condition is not met.

[0009] The replenishment part confirmation method of the present invention is a method for confirming parts to be replenished to a component supply unit of a component mounting device that removes parts set in a component supply unit and mounts them at component mounting positions on a board, and obtains from a memory unit substitute part information in which a higher-level part can be used as a substitute for a lower-level part but the lower-level part cannot be used as a substitute for the higher-level part, and determines that a part to be replenished to a component supply unit to be replenished, in which the lower-level part is designated as a designated part, is not identical to the designated part but is the higher-level part if the condition is met, and determines that the part cannot be replenished if the condition is not met.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An embodiment of the present invention will be described in detail below with reference to the drawings. The configurations, shapes, etc. described below are examples for the purpose of explanation, and can be modified as appropriate according to the specifications of the component mounting system, the component mounting device, and the information management device. In the following, the same reference numerals are used for corresponding elements in all the drawings, and duplicated explanations will be omitted. In FIG. 2 and in some parts described later, the X-axis in the board transport direction (the left-right direction in FIG. 2) and the Y-axis perpendicular to the board transport direction (the up-down direction in FIG. 2) are shown as two axes that are mutually perpendicular in the horizontal plane.

[0013] First, the configuration of component mounting system 1 will be described with reference to FIG. 1. Component mounting system 1 has a function of mounting components on a board to produce a mounted board. Component mounting system 1 is configured by connecting a plurality of component mounting devices W1-W3. Component mounting devices W1-W3 are connected to information management device 3 via communication network 2. Information management device 3 manages the production of mounted boards by component mounting system 1, and also supports the replenishing of components to the component supply units mounted on component mounting devices W1-W3. Note that the number of component mounting devices W1-W3 provided in component mounting system 1 is not limited to three, and may be one, two, four or more.

[0014] In FIG. 1, the component mounting system 1 includes a reader T used by an operator. The reader T includes a terminal communication unit Ta that wirelessly communicates with a management wireless communication unit 3a included in an information management device 3 to exchange information, a reading unit Tb that reads information recorded on a tag attached to a reel or the like that winds and stores a carrier tape that stores components, and a touch panel Tc that has a display function and an input function. If the tag attached to the reel or the like is an identifier that represents information about the components, such as a barcode or a two-dimensional code, the reading unit Tb optically reads the identifier. Also, if the tag is a memory element capable of wireless communication, such as an RFID tag, the reading unit Tb reads information about the components from the memory element. In this way, the reader T optically reads an identifier that represents information about the components, or reads information about the components from a memory element capable of wireless communication.

[0015] When a worker performs a parts replenishing operation to replenish parts in a parts supply unit (tape feeder, tray feeder, stick feeder, etc.), he or she performs a parts matching operation by using a reader T to read tags attached to reels, trays, sticks, etc. that store the parts. The reader T reads the information stored in the tag with a reading unit Tb, recognizes the part number that identifies the stored part, and transmits it to the information management device 3 or the part mounting device via the terminal communication unit Ta. The reader T also receives various information transmitted from the information management device 3 or the part mounting device, processes it for display, and displays it on the touch panel Tc.

[0016] Next, the configuration of component mounting devices W1 to W3 will be described with reference to Fig. 2. The component mounting devices W1 to W3 have the same configuration, and only component mounting device W1 will be described here. In component mounting device W1, a board transport section 5 is installed along the X-axis at the center of a base 4. Board transport section 5 transports board P carried in from upstream along the X-axis, and positions and holds it at a mounting position by a mounting head, which will be described below. Board transport section 5 also carries board P downstream after component mounting work has been completed. Component supply sections 6 are installed on both sides (front-rear directions of the Y-axis) of board transport section 5.

[0017] A tape feeder 7 is attached to each of a plurality of component supply positions provided along the X-axis in each component supply unit 6. The tape feeder 7 feeds a carrier tape, on which pockets for storing components are formed, in a direction (tape feed direction) from outside the component supply unit 6 toward the board transport unit 5, to supply components to a component removal position where the mounting head picks up the components. An operation button 7a and a lamp 7b are provided on the top surface of the tape feeder 7 at a position where an operator can operate the tape feeder 7 when the tape feeder 7 is attached to the component supply unit 6. The operation button 7a is operated by an operator for a component replenishment operation to replenish components to the tape feeder 7. The lamp 7b displays information such as a replenishment request, permission for component replenishment, and refusal to replenish components by changing color or flashing.

[0018] Furthermore, a tray feeder that supplies components placed on a tray, a stick feeder that supplies components aligned and held on a hollow stick, and the like are also attached to the component supply position provided in the component supply unit 6. The tape feeder 7, tray feeder, and stick feeder attached to the component supply unit 6 are component supply units that supply components to the mounting head.

[0019] When the component supply units are mounted in the component supply section 6, the unit control section of each component supply unit is electrically connected to the component mounting device control section 30 (see FIG. 3) of the component mounting device W1. Each component supply unit is assigned a unique component supply unit number. The component mounting device control section 30 communicates with the unit control section to recognize which component supply position in the component supply section 6 has a component supply unit with which component supply unit number.

[0020] In Fig. 2, a Y-axis table 8 equipped with a linear drive mechanism is disposed on both ends of the X-axis on the top surface of the base 4. A beam 9 similarly equipped with a linear mechanism is coupled to the Y-axis table 8 so as to be freely movable along the Y-axis. A mounting head 10 is attached to the beam 9 so as to be freely movable along the X-axis. The mounting head 10 is equipped with a plurality of suction units (not shown) that can hold a component and move up and down and rotate around a vertical axis (Z-axis). A suction nozzle (not shown) that suctions and holds the component is attached to the bottom end of each suction unit.

[0021] The Y-axis table 8 and the beam 9 constitute an XY unit 11 that moves the mounting head 10 along the X-axis and Y-axis. The XY unit 11 and the mounting head 10 constitute a component mounting mechanism that performs a component mounting operation of picking up components from the component supply unit 6 and mounting them at component mounting positions on the board P. In the component mounting operation, the mounting head 10 moves above the component supply unit 6, picks up predetermined components with each suction nozzle, moves above the board P, rotates the components held by each suction nozzle in a predetermined direction, and repeats a series of turns to mount the components at their respective component mounting positions.

[0022] 2, beam 9 is equipped with a board recognition camera 12 that is located on the underside of beam 9 and moves integrally with mounting head 10. As mounting head 10 moves, board recognition camera 12 moves above board P positioned at the mounting operation position of board transport section 5, and captures an image of a board mark (not shown) provided on board P to recognize the position of board P.

[0023] A component recognition camera 13 is installed between the component supply unit 6 and the board transport unit 5. When the mounting head 10, which has taken out a component from the component supply unit 6, is positioned above the component recognition camera 13, the component recognition camera 13 captures an image of the component held by the suction nozzle from below. When the mounting head 10 mounts the component on the board P, the component mounting position is corrected taking into account the recognition results of the board P by the board recognition camera 12 and the recognition results of the component by the component recognition camera 13.

[0024] 2, a touch panel 14 operated by an operator is provided in front of component mounting device W1 at a position where the operator works. Touch panel 14 displays various information on its display, and the operator inputs data and operates component mounting device W1 using buttons and the like displayed on the display.

[0025] Next, the configuration of the component mounting system 1 will be described with reference to Fig. 3. The information management device 3 includes a management storage unit 21, a component replenishing work support unit 26, and a management wireless communication unit 3a. The management storage unit 21 (storage unit) is a storage device, and stores component mounting information 22, supply position information 23, component information 24, alternative component group information 25, and the like. The component replenishing work support unit 26 includes, as internal processing units, an information acquisition unit 26a, a reader read information acquisition unit 26b, and a replenishing component confirmation unit 26c. The information management device 3 does not need to be configured as a single computer, and may be configured as a plurality of devices. For example, all or part of the storage device may be provided in a cloud via a server.

[0026] The component mounting information 22 stores information necessary for component mounting work, such as the names of components to be mounted on the board P and the component mounting positions, for each type of mounted board produced in the component mounting system 1. The supply position information 23 includes information identifying the component supply unit (tape feeder 7) mounted and information identifying the components supplied from the component supply unit, for each component supply position provided in the component supply section 6 of the component mounting devices W1 to W3. The component information 24 includes the size, electrical characteristics, etc. of the component for each component to be mounted on the board P. The alternative component group information 25 stores information relating to alternative component groups in which mutually substitutable parts are registered.

[0027] Here, the component mounting information 22 will be described in detail with reference to Fig. 4(a) and Fig. 6. Fig. 6 shows the board P on which components are mounted based on the component mounting information 22 shown in Fig. 4(a). The component mounting information 22 includes a component mounting position 40, a component mounting coordinate 41, a component name 42, and mounting component restriction information 43. The component mounting position 40 is information for identifying the mounting position of the component on the board P. The component mounting coordinate 41 is information including the mounting coordinate (XY coordinate) and the mounting angle (angle θ with the Z axis as the rotation axis) of the component. The component name 42 is information for identifying the component to be mounted at the component mounting position 40. In the component mounting information 22 shown in Fig. 4(a), the component name 42 is specified as the name of a regular component. A regular component is a component that is set before the start of production of a mounted board.

[0028] 4(a) and 6, components are mounted on ten component mounting positions 40, "M01" to "M10", on the board P. A component with a component name 42 of "A" is mounted on the component mounting position 40 "M01". Hereinafter, the component mounting position with the component mounting position 40 "M01" will be referred to simply as "component mounting position M01". Also, a component with a component name 42 of "A" will be referred to simply as "component A". The same applies to the other component mounting positions 40 and component names 42. That is, component B is mounted on component mounting positions M02 to M05, and component C is mounted on component mounting positions M06 to M10.

[0029] In FIG. 4(a), mounting component restriction information 43 is information that specifies (restricts) components (component names 42) that can be mounted at component mounting positions 40. At component mounting positions 40 for which component names 42 are registered in mounting component restriction information 43, only components with the registered component names 42 can be mounted. For example, "A" is registered in mounting component restriction information 43 for component mounting position M01, and only component A, which is a regular component, can be mounted. Also, "B" is registered in mounting component restriction information 43 for component mounting position M05, and only component B, which is a regular component, can be mounted. Note that for component mounting positions 40 for which mounting component restriction information 43 is blank, the component mounting information 22 does not restrict the components that can be mounted, and other components can be substituted.

[0030] Next, the details of the alternative part group information 25 will be described with reference to Fig. 4(b). The alternative part group information 25 includes a group number 44 that identifies an alternative part group, and an alternative part group 45. In the example shown in Fig. 4(b), part A and part B are registered as mutually interchangeable alternative parts in the alternative part group 45 with group number 44 "GR001". In other words, part A is interchangeable with part B, and part B is also interchangeable with part A, which is a two-way substitution condition. In this way, the alternative part group information 25 is a first alternative part information in which mutually interchangeable parts are registered as the alternative part group 45.

[0031] Next, the part information 24 will be described in detail with reference to Fig. 4(c). The part information 24 includes a part name 42, a part size 46, and a replaceable part 47. The part size 46 includes information about the size of the part, such as the length L, width W, and height H. The replaceable part 47 is information that specifies a part (part name 42) that can be replaced by that part. A part registered in the replaceable part 47 (a lower-level part) can be replaced by the registered part (a higher-level part).

[0032] For example, part C (a lower-level part) with part name 42 "C" has "A" and "B" registered as replaceable parts 47, and can be substituted for part A or part B (a higher-level part). Also, parts A and B have blank replaceable parts 47, and no higher-level parts exist. In other words, the relationship between part C and part A or part B is a one-way substitution condition, in which a lower-level part can be substituted for a higher-level part, but a higher-level part cannot be substituted for a lower-level part.

[0033] In other words, a one-way substitution condition is a relationship in which a higher-order component and a lower-order component have the same size and electrode position, but have different operating conditions and tolerances such as operating temperature range, resistance tolerance, and capacitance tolerance, so one (the higher-order component) can be substituted for the other (the lower-order component), but the reverse is not permitted. For example, if there are higher-order and lower-order components with the same nominal resistance, the lower-order component with a resistance tolerance of ±20% can be substituted for the higher-order component with a resistance tolerance of ±1%, but the reverse is not permitted.

[0034] In this way, the part information 24 is second substitute part information in which replaceable parts 47 (substitute parts) are registered for each part (part name 42). Then, in a case where part A (higher-level part) can be used as a substitute for part C (lower-level part), but part C (lower-level part) cannot be used as a substitute for part A (higher-level part), the second substitute part information (replaceable parts 47 in the part information 24) for part C (lower-level part) includes part A (higher-level part). Also, there is no second substitute part information for part A (higher-level part). Alternatively, second substitute part information that does not include part C (lower-level part) is registered. In the example of FIG. 4(c), the second substitute part information for part A is left blank.

[0035] Next, the supply position information 23 will be described in detail with reference to Fig. 5. The supply position information 23 includes a component supply position 50 set in the component supply section 6, a component supply unit 51, a designated component 52, a supply component 53, and supply component restriction information 54. The component supply unit 51 is information that specifies a component supply unit (such as a tape feeder 7, a tray feeder, or a stick feeder) that is attached to the component supply position 50.

[0036] The designated component 52 and the supplied component 53 are information specifying the component (component name 42) to be supplied from the component supply unit at the component supply position 50. The designated component 52 is the component name 42 of the component designated as the component to be supplied by the component supply unit at the component supply position 50 at the start of production of the mounted board. The supplied component 53 is the component name 42 of the component currently being supplied (current component) from the component supply unit at the component supply position 50. When a component to be supplied is replaced by a component replenishment operation, the designated component 52 is not updated, and only the component name 42 of the supplied component 53 is updated. The supplied component restriction information 54 is information that restricts the replacement of the part (component name 42) to be replenished to the component supply unit at the component supply position 50.

[0037] In FIG. 5, component supply units 51 of "TP01" and "TP02" are attached to component supply positions 50 of "FP01" and "FP02". Then, component A is supplied as a supply component 53 from the component supply units 51 of "TP01" and "TP02". Hereinafter, the component supply position 50 of "FP01" will be simply referred to as "component supply position FP01". Also, the component supply unit 51 of "TP01" will be simply referred to as "component supply unit TP01". The same applies to the other component supply positions 50 and component supply units 51. That is, a component B is supplied from the component supply units TP03-TP05 of the component supply positions FP03-FP05, and a component C is supplied from the component supply units TP06-TP08 of the component supply positions FP06-FP06.

[0038] In the component supply position FP01, "A" is registered as the supply component restriction information 54. In addition, in the component supply position FP05, "B" is registered as the supply component restriction information 54. That is, the parts that can be supplied to the component supply unit TP01 of the component supply position FP01 are limited to the part A, which is the same as the designated part 52. In addition, the parts that can be supplied to the component supply unit TP05 of the component supply position FP05 are limited to the part B, which is the same as the designated part 52. That is, the supply component restriction information 54 is also part substitution prohibition information that prohibits the substitution of parts. Note that the component supply unit of the component supply position 50 whose supply component restriction information 54 is blank is permitted to replenish only the parts specified as the supply parts 52 (current parts) or the designated parts 52, or the parts permitted to be substituted in the substitute part group information 25 or the replaceable parts 47 of the component information 24.

[0039] 3, information acquiring unit 26a (first information acquiring unit) acquires, from management storage unit 21 (storage unit), first alternative part information (alternative part group information 25) in which mutually substitutable parts are registered as an alternative part group 45, and second alternative part information (part information 24) in which substitutable parts (substitutable parts 47) for each part (part name 42) are registered. Information acquiring unit 26a also acquires supply part restriction information 54 from management storage unit 21 that restricts the substitution of parts to be replenished in part supply unit 51 included in supply position information 23.

[0040] The reader read information acquisition unit 26b acquires, via the management wireless communication unit 3a, information on parts read by the reader T from tags attached to reels or the like storing parts in a parts matching operation performed during a parts replenishing operation. That is, the reader T, the management wireless communication unit 3a, and the reader read information acquisition unit 26b constitute a replenishing parts information acquisition unit that acquires information on parts to be replenishing in a parts supply unit (such as the tape feeder 7).

[0041] 3, the refill part confirmation unit 26c judges whether or not a part (hereinafter referred to as a "refill part") requested to be refilled by a part supply unit (hereinafter referred to as a "refill target part supply unit") can be refilled during a part refill operation in which an operator refills a part supply unit (such as a tape feeder 7) with parts. That is, the refill part is a part specified by information acquired by the refill part information acquisition unit (reader T, management wireless communication unit 3a, reader read information acquisition unit 26b).

[0042] During component resupply work, when an operator operates operation button 7a of tape feeder 7 that is a component replenishment target, component supply position 50 of the component supply unit to be replenished (hereinafter referred to as "component supply position to be replenished") is transmitted to information management device 3 via component mounting device control unit 30. In addition, when an operator reads a tag attached to a reel that stores the replenished parts with reader T, the part name of the replenished part transmitted from reader T is acquired by reader read information acquisition unit 26b.

[0043] In Figure 3, the replenishment part confirmation unit 26c determines whether to permit or prohibit the replenishment of replenishment parts to the replenishment target part supply unit based on the part mounting information 22, supply position information 23, part information 24, and alternative part group information 25 stored in the management memory unit 21, and the acquired replenishment target part supply position and part name of the replenishment part.

[0044] Specifically, the replenishment part confirmation unit 26c permits part replenishment when the replenishment part is identical to the supply part 53 (current part) being supplied from the replenishment target part supply unit at the replenishment target part supply position, or is identical to the designated part 52 at the replenishment target part supply position (parts matching condition). For example, when the replenishment part is part C and the replenishment target part supply unit is part supply unit TP06, the supply part 53 (current part) is part C, which is identical to the replenishment part (see FIG. 5), so the replenishment part confirmation unit 26c determines the parts matching condition as "match" and permits part replenishment.

[0045] The replenishment part confirmation unit 26c permits part replenishment when the replenishment part is registered in the substitute part group 45 (first substitute part information) to which the designated part 52 or the supply part 53 (current part) of the replenishment target part supply position belongs (condition 1). For example, when the replenishment part is part A and the replenishment target part supply unit is part supply unit TP04, the designated part 52 and the supply part 53 are both part B, which do not match the replenishment part (part match condition is "mismatch") (see FIG. 5). However, since part A is registered in the substitute group 45 (group number GR001) to which part B belongs (see FIG. 4(b)), the replenishment part confirmation unit 26c judges that condition 1 (bidirectional substitution condition) is "Yes" and permits part replenishment to substitute part A for part B. When a part is substituted, the supply part 53 is updated to the substituted part name 42. Note that the replenishment part confirmation unit 26c does not judge condition 1 when condition 2 described later is set for the designated part 52.

[0046] The replenishment part confirmation unit 26c determines that part replenishment is permitted if the replenishment part is registered in the second substitute part information (replaceable part 47 in the part information 24) of the designated part 52 at the replenishment target part supply position (Condition 2). For example, when the replenishment part is part B and the replenishment target part supply unit is part supply unit TP07, the designated part 52 is part C, which does not match the replenishment part (part match condition is "mismatch") (see FIG. 5). However, since part B is registered in the replaceable part 47 for part C (FIG. 4(c)), the replenishment part confirmation unit 26c determines that condition 2 (one-way substitution condition) is "Yes" and permits part replenishment to substitute part B for part C.

[0047] 3, for a component supply unit in which the components to be replenished are restricted by the supply component restriction information 54 of the component mounting information 22, the replenishment component confirmation unit 26c determines whether the replenishment components are compatible with the supply component restriction information 54 (condition 3) regardless of the first substitute component information (condition 1) or the second substitute component information (condition 2). That is, for a component supply position 50 in which condition 3 (restriction condition) is set, the replenishment component confirmation unit 26c does not apply condition 1 (bidirectional substitution condition) and condition 2 (one-way substitution condition), but applies condition 3 to determine whether to permit component replenishment. If the replenishment components are compatible (condition 3 is "Yes"), the replenishment component confirmation unit 26c permits replenishment, and if they are not compatible (condition 3 is "No"), prohibits replenishment.

[0048] For example, if the replenishment part is part A and the part supply unit to be replenished is part supply unit TP01, "A" is registered in supply part restriction information 54 and matches the replenishment part (condition 3 is "Yes") (see FIG. 5). Therefore, replenishment part confirmation unit 26c permits the replenishment of part A. On the other hand, if the replenishment part is part B which is registered in the same alternative part group as part A and the part supply unit to be replenished is part supply unit TP01, replenishment part confirmation unit 26c does not permit the replenishment of part B since it does not match part A registered in supply part restriction information 54 (condition 3 is "No")

[0049] In this manner, the supplementary part confirmation unit 26c determines whether or not to permit supplementation based on the part matching condition, condition 1 (bidirectional substitution condition), and condition 2 (one-way substitution condition).

[0050] In the example of FIG. 5, at component supply position FP01, component substitution is restricted by condition 3 (restriction condition), and only replenishment of part A is permitted. Similarly, at component supply position FP05, only replenishment of part B is permitted. On the other hand, at component supply positions FP02-FP04 and FP06-FP08, the supply part restriction information 54 is blank, and part substitution is not prohibited. Therefore, at these component supply positions, part substitution is permitted in principle based on the alternative part group information 25 (condition 1). However, in the case of component supply positions FP06-FP08, when a replaceable part 47 is registered in the part information 24 of part C of the specified part 52, the judgment is made exceptionally based on condition 2. In other words, at component supply positions FP06-FP08, substitution of either part A or part B is permitted due to condition 2 (one-way substitution condition).

[0051] 3, replenishment part confirmation unit 26c outputs a message indicating that replenishment is permitted if replenishment is permitted, or a message indicating that replenishment is prohibited if replenishment is prohibited, to component mounting devices W1 to W3 or reader T. Upon receiving the output, touch panel 14 of component mounting devices W1 to W3, lamp 7b of tape feeder 7, or touch panel Tc of reader T displays permission or prohibition of replenishment of the part to be replenished.

[0052] In this way, the information management device 3 is a supplementary parts confirmation device that includes an information acquisition unit 26a (first information acquisition unit) that acquires first substitute part information in which mutually replaceable parts are registered as a substitute part group 45, and second substitute part information in which parts replaceable for each part (substitutable parts 47) are registered, a supplementary parts information acquisition unit (management wireless communication unit 3a, reader read information acquisition unit 26b) that acquires information on parts to be supplemented to the component supplying units, and a supplementary parts confirmation unit 26c that determines whether or not to permit supplementary parts based on the component matching condition, condition 1, condition 2, and condition 3, and that confirms the suitability of parts to be supplemented to the component supplying units of the component mounting devices W1 to W3. This makes it possible to confirm the suitability of parts to be supplemented to the component supplying units.

[0053] 3, component mounting devices W1 to W3 have the same configuration, and only component mounting device W1 will be described below. Component mounting device W1 includes a component mounting device control unit 30, a board transport unit 5, a tape feeder 7 (component supply unit), a mounting head 10, an XY unit 11, a board recognition camera 12, a component recognition camera 13, and a touch panel 14. Component mounting device control unit 30 includes a device storage unit 31, a component mounting control unit 36, a recognition unit 37, and a board transport control unit 38. Component mounting control device 30 (control unit) communicates with information management device 3 via communication network 2.

[0054] The device storage unit 31 is a storage device, and stores therein component mounting information 32, supply position information 33, component information 34, and alternative group information 35. The component mounting information 32, supply position information 33, component information 34, and alternative group information 35 store information on component mounting positions 40 of components to be mounted on the board P by the component mounting device W1, among the component mounting information 22, supply position information 23, component information 24, and alternative component group information 25 stored in the management storage unit 21 of the information management device 3, and the like.

[0055] 3, board transport control section 38 controls board transport section 5 to transport board P carried in from upstream to a mounting work position, position and hold it, and then carry it out downstream. Recognition section 37 recognizes and processes the image of the board mark captured by board recognition camera 12 to detect the position of board P. Recognition section 37 also recognizes and processes the image of the component held by the suction nozzle captured by component recognition camera 13 to detect the holding position of the component.

[0056] Based on the component mounting information 32, the component mounting control unit 36 ​​controls the tape feeder 7 (component supply unit), mounting head 10, XY unit 11, board recognition camera 12, and component recognition camera 13 to take out components from the component supply unit 6 and mount them at component mounting positions 40 on the board P held at the mounting work position. In other words, the component mounting control unit 36, recognition unit 37, tape feeder 7 (component supply unit), mounting head 10, XY unit 11, board recognition camera 12, and component recognition camera 13 form a component mounting work unit 39 that takes out components from the component supply unit and mounts them at component mounting positions 40 based on the component mounting information 32.

[0057] Now, the component mounting operation on the board P by the component mounting operation unit 39 will be described with reference to Fig. 7. Fig. 7 shows a schematic diagram of a component mounting operation in which the component mounting operation unit 39 mounts components on the component mounting positions 40 of the board P based on the component mounting information 22 (component mounting information 32) shown in Fig. 4(a) from the component supply unit 6 in which the component supply unit 51 is arranged at the component supply position 50 based on the supply position information 23 (supply position information 33) shown in Fig. 5. The component mounting operation unit 39 mounts the components on the component mounting positions M01 to M10 of the board P, respectively, based on the component mounting information 32, supply position information 33, component information 34, and alternative group information 35.

[0058] Specifically, because "A" is registered for component mounting position M01 in mounting component restriction information 43, component mounting work unit 39 mounts component A supplied by component supply units TP01 and TP02 at component mounting position M01. Similarly, because "B" is registered for component mounting position M05 in mounting component restriction information 43, component mounting work unit 39 mounts component B supplied by component supply units TP03-TP05 at component mounting position M05.

[0059] Moreover, the mounting component restriction information 43 for the component mounting positions M02 to M04 and M06 to M10 is blank. Furthermore, the components A and B are registered in the same alternative component group 45 (group number GR001). Therefore, the component mounting work unit 39 mounts either the component A supplied by the component supply units TP01 and TP02, or the component B supplied by the component supply units TP03 to TP05, at the component mounting positions M02 to M04. Furthermore, the components A and B are registered as the replaceable components 47 for the component C. Therefore, the component mounting work unit 39 mounts either the component A supplied by the component supply units TP01 and TP02, or the component B supplied by the component supply units TP03 to TP05, or the component C supplied by the component supply units TP06 to TP08, at the component mounting positions M06 to M10.

[0060] Next, a method for confirming whether the components to be replenished to the component supply units of the component mounting devices W1 to W3 in the component mounting system 1 are appropriate will be described with reference to the flow chart in Fig. 8. First, the information acquisition unit 26a acquires, from the management storage unit 21 (storage unit), first alternative component information in which mutually replaceable components are registered as an alternative component group 45, second alternative component information in which parts replaceable for each component (replaceable parts 47) are registered, and supply component restriction information 54 that restricts the replacement of the components to be replenished to the component supply units (ST1). Next, the system waits until the operator operates the operation button 7a of the tape feeder 7 to request a component supply (ST2) ("None" in ST3).

[0061] When there is a parts supply request (operation button 7a is operated) ("Yes" in ST3), information on the parts supply position to be replenished and the parts supply unit to be replenished is acquired, and the system waits ("No" in ST5) until an operator reads the tag attached to the reel with reader T (ST4). When information on the parts to be replenished to the parts supply unit is acquired from reader T ("Yes" in ST5), replenishment parts confirmation unit 26c judges whether the replenishment parts are the same as supplied parts 53 (current parts) or specified parts 52 at the parts supply position to be replenished (parts matching condition) (ST6).

[0062] If the replenishment part matches the supply part 53 or the specified part 52 ("match" in ST6), the replenishment part confirmation unit 26c notifies (outputs) permission for part replenishment (ST7). In this case, the part is not substituted, and a part with the same part name 42 is replenished. For example, when the replenishment part is part A and the part supply unit to be replenished is part supply unit TP02 (FIG. 5), the replenishment part matches the supply part 53 (part A). Therefore, the replenishment part confirmation unit 26c judges that there is a "match" in ST6 and notifies (outputs) permission for part replenishment (ST7).

[0063] 8, if the replenishment part does not match the current part or the designated part 52 of the replenishment target part supply location ("Mismatch" in ST6), the replenishment part confirmation unit 26c judges whether or not the supply part restriction information 54 is registered in the replenishment target part supply location, that is, whether or not the condition 3 exists (ST8). If the condition 3 exists ("Yes" in ST8), the replenishment part confirmation unit 26c judges whether or not the part satisfies the supply part restriction information 54 (ST9). If it does match (Yes in ST9), the replenishment part confirmation unit 26c notifies (outputs) the permission for parts replenishment and also updates the supply part 53 in the supply location information 23 to the replenished part name 42 (ST10).

[0064] 8, when condition 3 does not exist ("NO" in ST8), the refill part confirmation unit 26c judges whether or not there is second substitute part information (substitutable part 47) of the designated part 52 of the refill target part supply position (ST11). When there is second substitute part information ("YES" in ST11), the refill part confirmation unit 26c judges whether or not the refill part is registered in the second substitute part information (substitutable part 47) of the designated part 52 of the refill target part supply position, that is, whether or not condition 2 is satisfied (ST12). Then, when the refill part confirmation unit 26c judges that condition 2 is satisfied (Yes in ST12), it notifies permission for part refill (ST10).

[0065] For example, when the replenishment part is part B and the part supply unit to be replenished is part supply unit TP08, part B is registered in replaceable parts 47 in part information 24 of specified part 52 (part C) (see Fig. 4(c) and Fig. 5), so replenishment part confirmation unit 26c judges "Yes" in ST11 and branches to ST12 to determine whether condition 2 is met. Since part B is registered in replaceable parts 47 of part C, replenishment part confirmation unit 26c judges that condition 2 is met (Yes in ST12) and notifies permission for part replenishment (ST10).

[0066] 8, if condition 2 does not exist ("None" in ST11), the replenishment part confirmation unit 26c judges whether the replenishment part is registered in the substitute part group 45 (first substitute part information) to which the specified part 52 of the replenishment target part supply position belongs, that is, whether condition 1 (two-way substitution condition) is satisfied (ST13). If the replenishment part confirmation unit 26c judges that condition 1 is satisfied (Yes in ST13), it notifies (outputs) permission for part replenishment (ST10).

[0067] For example, if the replenishment part is part B and the part supply unit to be replenished is part supply unit TP02, part B is registered in the alternative group 45 (group number GR001) of the specified part 52 (part A) (see Figures 4(b) and 5), so the replenishment part confirmation unit 26c determines that condition 1 is satisfied (Yes in ST13) and notifies permission for part replenishment (ST10).

[0068] In FIG. 8, if none of Condition 3 (ST9), Condition 2 (ST12), and Condition 1 (ST13) are satisfied (No), the replenishment part confirmation unit 26c notifies (outputs) that parts replenishment is not permitted (ST14).

[0069] As described above, the component mounting system 1 of this embodiment includes a management storage unit 21 (storage unit) that stores first alternative part information in which mutually replaceable parts are registered as an alternative part group 45, and second alternative part information in which parts replaceable for each part (replaceable parts 47) are registered, a component mounting work unit 39 that removes parts from the component supply unit and mounts them at the component mounting position 40, a supplementary part information acquisition unit (management wireless communication unit 3a, reader read information acquisition unit 26b) that acquires information on parts to be supplemented in the component supply unit, and a supplementary part confirmation unit 26c that determines whether to permit or prohibit supplementary parts based on the component matching condition, condition 1, and condition 2. This makes it possible to confirm whether the parts to be supplemented in the component supply unit are appropriate.

[0070] In the above embodiment, an example has been described in which a worker performs parts replenishing work while checking parts with the reader T, but the parts replenishing work may be performed by an automatic parts replenishing device having an articulated robot (such as a self-propelled robot). In this case, the reader is built into the automatic parts replenishing device, and the parts replenishing work is performed in the automatic parts replenishing device. The replenishing part confirmation unit 26c outputs a replenishing permission notice or a replenishing non-permission notice to the automatic parts replenishing device. [Industrial Applicability]
