DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] 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 explanation, and can be appropriately changed according to the specifications of the production system, production line, working device, inspection device, board supply and storage device, management device, confirmation device, automatic guided vehicle, etc. In the following, the same reference numerals are used for corresponding elements in all drawings, and duplicated explanations are omitted. In FIG. 2 and some parts described later, the X direction (left and right direction in FIG. 2(a)) of the board transport direction and the Y direction (up and down direction in FIG. 2(a)) perpendicular to the board transport direction are shown as two axial directions perpendicular to each other in the horizontal plane. In FIG. 2(b), the Z direction (up and down direction in FIG. 2(b)) is shown as the height direction perpendicular to the horizontal plane.

[0012] First, the configuration of the production system 1 will be described with reference to Fig. 1. The production system 1 is configured to manage a production line L by a management device 3 connected via a communication network 2. The production line L is equipped with, in order from upstream in the board transport direction (left side in Fig. 1), a first board supply and storage device M1, a solder printing device M2, a first inspection device M3, a second board supply and storage device M4, component mounting devices M5 and M6, a second inspection device M7, a third board supply and storage device M8, a reflow device M9, and a fourth board supply and storage device M10.

[0013] Each device constituting the production line L has a board transport mechanism for transporting boards, and performs work to produce mounted boards by mounting components on the boards while transporting the boards from upstream to downstream devices. The first board supply and storage device M1 performs a board supplying work of removing boards from slots of a magazine S having multiple slots and supplying them to the downstream solder printing device M2. The solder printing device M2 performs a solder printing work of printing solder on boards carried in from upstream through a screen mask attached to the printing work section. The first inspection device M3 performs a printing inspection work of acquiring an image of the solder (inspection object) printed on the board with an inspection camera and judging whether the solder printing condition is good or bad.

[0014] In FIG. 1, the second board supply and storage device M4 stores boards with poor solder printing in a magazine S, and transports boards with good solder printing to the downstream component mounting device M5. The component mounting devices M5 and M6 perform a component mounting operation in which components are mounted on boards on which solder has been printed by a mounting operation unit. Note that the production line L is not limited to a configuration in which the number of component mounting devices M5 and M6 is two, and may include one or three or more component mounting devices M5 and M6. The second inspection device M7 uses an inspection camera to obtain images of the components (inspection objects) mounted on the board, and performs a mounting inspection operation to determine whether the mounting state of the components is good or bad.

[0015] The third board supplying and storing device M8 stores boards with poorly mounted components in a magazine S, and transports boards with good mounted components to a downstream reflow device M9. The reflow device M9 performs a reflow operation in which the boards with mounted components are heated to melt the solder and then solidify it. The fourth board supplying and storing device M10 receives boards sent out from the upstream reflow device M9, and performs a board recovery operation to store them in the magazine S.

[0016] The production line L may be provided, between the reflow device M9 and the fourth board supplying and storing device M10, with an inspection device that uses an inspection camera to obtain images of components (inspection objects) soldered to the boards and judge whether the components are mounted properly, and a board supplying and storing device that stores boards with defective component mounting states in a magazine S and transports good boards downstream. Hereinafter, unless there is a need to distinguish between them, the first board supplying and storing device M1, the second board supplying and storing device M4, the third board supplying and storing device M8, and the fourth board supplying and storing device M10 will be referred to as "board supplying and storing device Ms", the solder printing device M2, the component mounting devices M5 and M6, and the reflow device M9 will be referred to as "working device Mw", and the first inspection device M3 and the second inspection device M7 will be referred to as "inspection device Mi".

[0017] 1, the production system 1 includes a confirmation device 4 arranged in a repair work area A located away from the production line L. The confirmation device 4 is connected to a communication network 2, and has a function of acquiring and displaying images of the object to be inspected and the inspection results from the inspection device Mi, and a function of receiving a pass / fail judgment and transmitting an unloading command to the board supply and storage device Ms or the management device 3. The confirmation device 4 also has a function of receiving a work history of repair work performed by an operator on a defective board, and a function of transmitting the work history to the repair device Mw or the management device 3.

[0018] The production system 1 is equipped with a plurality of automated guided vehicles V that transport magazines S between the production line L, the repair work area A, and a preparation area (not shown). The automated guided vehicles V deliver and receive magazines S between the board supply and storage device Ms. For example, the automated guided vehicle V transports the magazine S that stores boards before work from the preparation area to the first board supply and storage device M1. The automated guided vehicle V also receives the magazine S that stores boards that have already been worked on from the fourth board supply and storage device M10 and transports it to the preparation area.

[0019] In addition, the automated guided vehicle V receives the magazine S containing defective boards from the second board supply and storage device M4 or the third board supply and storage device M8 and transports it to the repair work area A. In addition, the automated guided vehicle V transports the magazine S containing repaired boards from the repair work area A to the first board supply and storage device M1, the second board supply and storage device M4, or the third board supply and storage device M8. Based on commands transmitted from the management device 3 or the like, the automated guided vehicle V moves on its own while detecting tapes installed on the floor and estimating its own position using a laser range scanner or camera, and performs the transport work, handover work, etc. of the magazine S.

[0020] Next, the configuration of the substrate supplying and storing device Ms will be described with reference to Figures 2(a) and 2(b). The substrate supplying and storing device Ms includes a carry-in mechanism 10, a transport mechanism 11, an unloading mechanism 12, a lifting mechanism 13, a magazine holding mechanism 14, a substrate transfer mechanism 15, an identification information acquisition unit 16, a supply storage unit 20, and a supply control unit 21. The carry-in mechanism 10, the transport mechanism 11, and the unloading mechanism 12 are arranged side by side in the substrate transport direction (X direction), and each includes a pair of conveyors that support opposing ends of the substrate in a direction (Y direction) perpendicular to the substrate transport direction and transport the substrate from upstream to downstream.

[0021] A carry-in mechanism 10 disposed upstream receives a substrate from an upstream device, carries it into a substrate supply and storage device Ms, and hands it over to a transport mechanism 11 disposed in the center. The transport mechanism 11 transports the substrate received from the carry-in mechanism 10 and hands it over to an unloading mechanism 12 disposed downstream. The unloading mechanism 12 transports the substrate received from the transport mechanism 11 and hands it over to a downstream device.

[0022] In Fig. 2, the transport mechanism 11 is raised and lowered vertically (in the Z direction) by the lifting mechanism 13 (arrow b2 in Fig. 4(a) and arrow b8 in Fig. 5(c)). When the transport mechanism 11 receives a substrate from the load-in mechanism 10 or delivers a substrate to the unloading mechanism 12, the lifting mechanism 13 positions the conveyor of the transport mechanism 11 at a substrate transport height position that matches the height position of the conveyors of the load-in mechanism 10 and the unloading mechanism 12 (the state in Fig. 3). In this way, the transport mechanism 11 is raised and lowered by the lifting mechanism 13, and transports the substrate received from upstream downstream.

[0023] A magazine holding mechanism 14 that detachably holds the magazine S is disposed below the transport mechanism 11. A plurality of slots SL in which substrates are accommodated are formed in the magazine S in the vertical direction (Z direction). When the lifting mechanism 13 raises and lowers the transport mechanism 11 with the magazine holding mechanism 14 holding the magazine S, the magazine S held by the magazine holding mechanism 14 also rises and lowers in accordance with the transport mechanism 11. In this manner, the magazine holding mechanism 14 rises and lowers by the lifting mechanism 13, and holds the magazine S in a detachable manner. With the magazine holding mechanism 14 holding the magazine S, the magazine S is disposed below the transport mechanism 11.

[0024] 2, a magazine insertion port 22 that opens to the front surface of the substrate supplying and storing device Ms (the lower side in FIG. 2(a)) is formed below the magazine holding mechanism 14. The magazine S is attached to and detached from the magazine holding mechanism 14 through the magazine insertion port 22. The substrate transfer mechanism 15 is disposed between a pair of conveyors of the carry-in mechanism 10 in a plan view. The substrate transfer mechanism 15 is configured to include a pusher 17 that extends in the X direction and has a contact portion 17a at its downstream end that contacts the upstream end portion of the substrate, a pusher moving mechanism 18 that moves the pusher 17 in and out in the X direction, and a pusher lifting mechanism 19 that moves the pusher moving mechanism 18 up and down.

[0025] When the carry-in mechanism 10 carries in a substrate, the pusher lifting mechanism 19 positions the contact portion 17a at a standby height position where it does not interfere with the substrate being transported (the state in FIG. 4(a) and FIG. 6(a)). When the pusher 17 moves the substrate downstream, the pusher lifting mechanism 19 positions the contact portion 17a at a substrate transfer height position where it abuts against the upstream end of the substrate (the state in FIG. 4(b) and FIG. 6(b)).

[0026] 2, the identification information acquisition unit 16 is configured to include a camera disposed above the unloading mechanism 12 and reading an identification mark attached to the board. The identification information acquisition unit 16 acquires identification information associated with the board based on the identification mark read by the camera. That is, the identification information acquisition unit 16 reads the identification mark attached to the board and acquires the identification information associated with the board. The acquired identification information is transmitted to the working device Mw, the inspection device Mi, the other board supply and storage devices Ms, the management device 3, and the confirmation device 4 via the communication network 2.

[0027] The supply control unit 21 (control unit) controls the loading mechanism 10, the transport mechanism 11, the unloading mechanism 12, the lifting mechanism 13, the magazine holding mechanism 14, the substrate transfer mechanism 15 (pusher moving mechanism 18, pusher lifting mechanism 19), and the identification information acquisition unit 16 based on various information stored in the supply memory unit 20 and commands sent from the management device 3.

[0028] Here, referring to Fig. 3, a substrate passing process in which the substrate supplying and accommodating device Ms does not accommodate a substrate and carries it downstream will be described. The substrate passing process is performed in a state in which the lifting mechanism 13 positions the transport mechanism 11 at the substrate transport height position. In Fig. 3(a), the supply control unit 21 operates the conveyor of the carry-in mechanism 10 to carry in the substrate B from the upstream device (arrow a1). In Fig. 3(b), the supply control unit 21 then operates the conveyor of the transport mechanism 11 to transfer the substrate B from the carry-in mechanism 10 to the transport mechanism 11, and the transport mechanism 11 transports the substrate B downstream (arrow a2). In Fig. 3(c), the supply control unit 21 then operates the conveyor of the carry-out mechanism 12 to transfer the substrate B from the transport mechanism 11 to the carry-out mechanism 12, and the substrate B is carried out to the downstream device (arrow a3).

[0029] Next, with reference to Figures 4 and 5, a substrate accommodation process in which the substrate supplying and accommodating device Ms accommodates the substrate B in the magazine S will be described. In Figure 4(a), first, the supply control unit 21 operates the conveyor of the carry-in mechanism 10 to carry in the substrate B from an upstream device (arrow b1). The supply control unit 21 also operates the lifting mechanism 13 to raise the magazine S to a substrate accommodation height position where the substrate B transported from the carry-in mechanism 10 can be accommodated in an empty slot SL (arrow b2). In Figure 4(b), the downstream end of the substrate B transported by the carry-in mechanism 10 enters an empty slot SL, and the upstream end moves to a position where it does not interfere with the pusher 17 (arrow b3).

[0030] Next, the supply control unit 21 operates the pusher lifting mechanism 19 of the substrate transfer mechanism 15 to raise the pusher movement mechanism 18, which is located at the standby height position, to a substrate transfer height position where the abutment portion 17a of the pusher 17 can abut against the upstream end of the substrate B (arrow b4). In Fig. 4(c), the supply control unit 21 then operates the pusher movement mechanism 18 of the substrate transfer mechanism 15 to move the pusher 17 downstream and push the upstream end of the substrate B with the abutment portion 17a to move the substrate B to the accommodation position in the slot SL (arrow b5).

[0031] In Fig. 5(a), the supply control unit 21 then operates the pusher movement mechanism 18 to move the pusher 17 upstream and retract the contact portion 17a from within the slot SL (arrow b6). In Fig. 5(b), the supply control unit 21 then operates the pusher lifting mechanism 19 to lower the pusher movement mechanism 18 to the standby height position (arrow b7). The supply control unit 21 also operates the lifting mechanism 13 to lower the transport mechanism 11 and magazine S to the substrate transport height position (arrow b8).

[0032] In this way, the supply control unit 21 (control unit) controls the lifting mechanism 13 so that the substrate B received from upstream is accommodated in an empty slot SL among the multiple slots SL of the magazine S. That is, the lifting mechanism 13 raises and lowers the height position of the magazine S relative to the substrate transfer mechanism 15. Then, the substrate transfer mechanism 15 transfers the substrate B received from upstream to one of the multiple slots SL of the magazine S.

[0033] Next, referring to Fig. 6 and Fig. 7, a substrate unloading process in which the substrate supplying and storing device Ms unloads the substrate B1 stored in the magazine S to a downstream device will be described. In Fig. 6(a), substrates B including the substrate B1 are stored in each of a plurality of (three in this case) slots SL of the magazine S. In Fig. 6(b), first, the supply control unit 21 operates the lifting mechanism 13 to raise the magazine S to a height position at which the stored substrate B1 is sent downstream (arrow c1). In addition, the supply control unit 21 operates the pusher lifting mechanism 19 of the substrate transfer mechanism 15 to raise the pusher moving mechanism 18 to a height position equal to the substrate transfer height position at which the abutment portion 17a of the pusher 17 can abut against the upstream end of the substrate B1 (arrow c2).

[0034] In Fig. 6(c), the supply control unit 21 then operates the pusher movement mechanism 18 of the substrate transfer mechanism 15 to move the pusher 17 downstream and push the upstream end of the substrate B1 in the slot SL with the abutting portion 17a, moving the substrate B1 until at least the downstream end is transferred to the discharge mechanism 12 (arrow c3). In Fig. 7(a), the supply control unit 21 then operates the conveyor of the discharge mechanism 12 to transport the substrate B1 pushed out of the slot SL downstream (arrow c4). The supply control unit 21 also operates the pusher movement mechanism 18 to move the pusher 17 upstream and retract the abutting portion 17a from within the slot SL (arrow c5).

[0035] 7(b), the substrate B1 transferred to the unloading mechanism 12 is unloaded to a downstream device (arrow c6). The supply control unit 21 also operates the pusher lifting mechanism 19 to lower the pusher moving mechanism 18 to the standby height position (arrow c7). The supply control unit 21 also operates the lifting mechanism 13 to lower the transport mechanism 11 and the magazine S to the substrate transport height position (arrow c8).

[0036] In this manner, the supply control unit 21 (control unit) controls the lifting mechanism 13 so that the substrate B1 to be discharged can be sent out from the slot SL in which the substrate B1 to be discharged is accommodated among the multiple slots SL of the magazine S. In addition, the substrate transfer mechanism 15 is a substrate discharge mechanism that pushes out the substrate B1 accommodated in the slot SL downstream.

[0037] In the above-mentioned substrate supplying and storing apparatus Ms, substrate transfer mechanism 15 also serves as the substrate output mechanism, but substrate supplying and storing apparatus Ms may be configured to include a substrate output mechanism in addition to substrate transfer mechanism 15. For example, the substrate output mechanism may be disposed between a pair of conveyors of unloading mechanism 12 in a plan view, and configured to pull out substrate B1 from slot SL. Magazine S is disposed at a position where the direction in which substrate transfer mechanism 15 transfers substrate B1 received from upstream to slot SL coincides with the direction in which the substrate output mechanism outputs substrate B1 accommodated in slot SL downstream.

[0038] Next, with reference to Figures 8 to 10, a magazine delivery process in which the magazine S transported by the automated guided vehicle V is delivered to the substrate supply and storage device Ms will be described. In Figures 8(a) and 10, the automated guided vehicle V is equipped with a delivery memory unit 30, a delivery control unit 31, a traveling mechanism 32, a magazine placement mechanism 33, and a delivery wireless communication unit 34. The delivery wireless communication unit 34 is a wireless communication device, and transmits and receives various information and commands to and from the management device 3.

[0039] The transport control unit 31 controls the traveling mechanism 32 and the magazine placement mechanism 33 based on various information stored in the transport storage unit 30, which is a storage device, and commands sent from the management device 3. The traveling mechanism 32 includes a motor for driving the wheels, and drives the automated guided vehicle V to stop it at a predetermined position. The magazine placement mechanism 33 is disposed on the top of the automated guided vehicle V, and has the function of holding or releasing the magazine S placed thereon.

[0040] 8 and 9 show a process of transferring an empty magazine S that does not contain a substrate B in a slot SL transported by an automated guided vehicle V to a substrate supplying and storing device Ms. The substrate supplying and storing device Ms shown in FIGS. 8 and 9 shows a configuration seen from the position AA in FIG. 2(b). In FIG. 8(a), an empty magazine S placed on an automated guided vehicle V is held by a magazine placing mechanism 33. The transport control unit 31 controls the traveling mechanism 32 to move the automated guided vehicle V toward the front of the substrate supplying and storing device Ms (arrow d1), enter the magazine insertion port 22, and stop it at the magazine transfer position below the magazine holding mechanism 14 (arrow d2 in FIG. 8(b)).

[0041] 8(c), when the automated guided vehicle V holding the magazine S stops at the magazine transfer position, the supply control unit 21 operates the lifting mechanism 13 to lower the magazine holding mechanism 14 from the substrate transport height position (arrow d3), and operates the magazine holding mechanism 14 to hold the upper part of the magazine S held by the automated guided vehicle V. When the magazine holding mechanism 14 holds the magazine S, the transport control unit 31 operates the magazine placement mechanism 33 to release the held magazine S.

[0042] In Fig. 9(a), when the automated guided vehicle V releases the magazine S, the supply control unit 21 operates the lifting mechanism 13 to raise the magazine holding mechanism 14 to the substrate transport height position (arrow d4). This allows the magazine S to be transferred from the automated guided vehicle V to the substrate supply and storage device Ms. In Fig. 9(b), after the magazine S has been transferred, the transport control unit 31 controls the traveling mechanism 32 to move the automated guided vehicle V from the magazine insertion port 22 to the outside of the substrate supply and storage device Ms (arrow d5).

[0043] 8 and 9 show the magazine delivery process in which the magazine S is delivered from the automated guided vehicle V to the substrate supplying and storing device Ms, but the magazine receiving process in which the automated guided vehicle V receives the magazine S from the substrate supplying and storing device Ms is performed in the reverse order to the magazine delivery process described above. That is, the automated guided vehicle V not holding the magazine S moves to the magazine delivery position in the substrate supplying and storing device Ms, and the lifting mechanism 13 lowers the magazine holding mechanism 14 holding the magazine S to place it on the magazine placement mechanism 33 of the automated guided vehicle V.

[0044] Next, the magazine placement mechanism 33 holds the magazine S, and when the magazine holding mechanism 14 releases the magazine S, the lifting mechanism 13 raises the magazine holding mechanism 14 to the substrate transport height position, and the automated guided vehicle V, which has received the magazine S, moves out of the substrate supply and storage device Ms. In this manner, the magazine S is transported by the automated guided vehicle V, and the magazine S is delivered between the substrate supply and storage device Ms and the automated guided vehicle V. The lifting mechanism 13 and magazine holding mechanism 14 of the substrate supply and storage device Ms constitute a magazine transfer mechanism that delivers the magazine S to and from the automated guided vehicle V.

[0045] 10, the timing of the processes in which the transport control unit 31 of the automated guided vehicle V and the supply control unit 21 of the substrate supply and storage device Ms cooperate in the magazine delivery process and the magazine receiving process is adjusted via the management device 3. That is, information is transmitted and received wirelessly between the automated guided vehicle V and the management device 3 by the transport wireless communication unit 34 of the automated guided vehicle V and the management wireless communication unit 67 included in the management device 3.

[0046] Furthermore, information is transmitted and received between the management device 3 and the board supplying and storage device Ms by the management communication unit 68 provided in the management device 3 and the supply communication unit 26 of the board supplying and storage device Ms via the communication network 2. Note that the board supplying and storage device Ms may be provided with wireless communication means and may transmit and receive information directly to and from the automatic guided vehicle V without going through the management device 3, thereby adjusting the timing of the magazine delivery process and the magazine receiving process.

[0047] As described above, the substrate supplying and storing apparatus Ms of this embodiment includes a lifting mechanism 13, a control unit (supply control unit 21) that controls the lifting mechanism 13, a transport mechanism 11 that transports the substrate B received from upstream downstream and lifts and lowers it with the lifting mechanism 13, a magazine S having multiple slots SL, a substrate transfer mechanism 15 that transfers the substrate B received from upstream to one of the multiple slots SL, and a substrate output mechanism (substrate transfer mechanism 15) that sends the substrate B stored in the slot SL downstream. The lifting mechanism 13 raises and lowers the position of the magazine S relative to the substrate transfer mechanism 15 and the substrate output mechanism. This allows the substrate supplying and storing apparatus Ms (storage apparatus) to temporarily store multiple substrates B, and is capable of a substrate passing process in which the substrate B received from upstream is carried out downstream without being stored in the magazine S.

[0048] It is not necessary for the first substrate supply and storage device M1, the second substrate supply and storage device M4, the third substrate supply and storage device M8, and the fourth substrate supply and storage device M10, which are the substrate supply and storage devices Ms, to have all of the mechanisms described above. For example, the first substrate supply and storage device M1, which is a substrate input device provided at the beginning of the production line L, does not have to have the carry-in mechanism 10, the transport mechanism 11, and the substrate transfer mechanism 15. That is, the first substrate supply and storage device M1 (input device) capable of inputting a plurality of substrates B may have a lifting mechanism 13, a control unit (supply control unit 21) that controls the lifting mechanism 13, a magazine S having a plurality of slots SL, and a substrate output mechanism (substrate transfer mechanism 15) that sends out the substrates B stored in the slots SL downstream, and the lifting mechanism 13 may be configured to raise and lower the height position of the magazine S relative to the substrate output mechanism.

[0049] Furthermore, the fourth substrate supplying and storing device M10, which is a substrate recovering device provided at the rear of the production line L, does not necessarily have to include a substrate unloading mechanism, a transport mechanism 11, or an unloading mechanism 12. In other words, the fourth substrate supplying and storing device M10 (recovering device) capable of recovering multiple substrates B may include a lifting mechanism 13, a control unit (supply control unit 21) that controls the lifting mechanism 13, a magazine S having multiple slots SL, and a substrate transfer mechanism 15 that transfers substrates B received from upstream to the slots SL, with the lifting mechanism 13 being configured to raise and lower the height position of the magazine S relative to the substrate transfer mechanism 15.

[0050] Furthermore, the second substrate supply and storage device M4 and the third substrate supply and storage device M8, which are storage devices provided in the middle of the production line L, do not need to be equipped with a substrate unloading mechanism if the function of re-inserting the substrate B stored in the magazine S downstream is not required. That is, a storage device capable of storing multiple substrates B may be configured to include a lifting mechanism 13, a control unit (supply control unit 21) that controls the lifting mechanism 13, a transport mechanism 11 that transports the substrate B received from upstream downstream and lifts and lowers it with the lifting mechanism 13, a magazine S having multiple slots SL, and a substrate transfer mechanism 15 that transfers the substrate B received from upstream to the slots SL, with the lifting mechanism 13 raising and lowering the height position of the magazine S relative to the substrate transfer mechanism 15.

[0051] Furthermore, the second substrate supply and storage device M4 and the third substrate supply and storage device M8, which are storage devices provided in the middle of the production line L, may not be equipped with the transport mechanism 11 if there is no need for the function of substrate passing processing to convey the substrate B received from upstream downstream without storing it in the magazine S. That is, a storage device capable of temporarily storing a substrate may be configured to include a lifting mechanism 13, a control unit (supply control unit 21) that controls the lifting mechanism 13, a magazine S having a plurality of slots SL, a substrate transfer mechanism 15 that transfers the substrate B received from upstream to the slots SL, and a substrate output mechanism (substrate transfer mechanism 15) that sends out the substrate B stored in the slots SL downstream, with the lifting mechanism 13 raising and lowering the height position of the magazine S relative to the substrate transfer mechanism 15 and the substrate output mechanism.

[0052] Next, the configuration of the control system of the production system 1 will be described with reference to Fig. 10. The production system 1 is configured to include a production line L, an automatic guided vehicle V, a management device 3, and a confirmation device 4. The production line L is equipped with board supply and storage devices Ms (first board supply and storage device M1, second board supply and storage device M4, third board supply and storage device M8, fourth board supply and storage device M10), a working device Mw (solder printing device M2, component mounting devices M5, M6), and an inspection device Mi (first inspection device M3, second inspection device M7).

[0053] 10, each device (substrate supply and storage device Ms, operation device Mw, inspection device Mi, management device 3, confirmation device 4) has a communication device (supply communication unit 26, operation communication unit 47, inspection communication unit 59, management communication unit 68, confirmation communication unit 75) and transmits and receives data with other devices via communication network 2. Each device also has an input device (supply reception unit 25, operation reception unit 46, inspection reception unit 58, management reception unit 66, confirmation reception unit 74) such as a keyboard, touch panel, or mouse used when inputting operation commands or data.

[0054] In addition, each device is equipped with a display device (supply display unit 24, work display unit 45, inspection display unit 57, management display unit 65, confirmation display unit 73) such as an LCD panel that displays various data stored in the memory device (supply memory unit 20, work memory unit 40, inspection memory unit 50, management memory unit 60, confirmation memory unit 70) and various information such as a screen for operation using the input device.

[0055] 10, the substrate supply and storage device Ms includes a carry-in mechanism 10, a transport mechanism 11, an unloading mechanism 12, a lifting mechanism 13, a magazine holding mechanism 14, a substrate transfer mechanism 15, an identification information acquisition unit 16, a supply memory unit 20, a supply control unit 21, a supply receiving unit 23, a supply display unit 24, a supply acceptance unit 25, and a supply communication unit 26. The working device Mw includes a work memory unit 40, a work control unit 41, a work transport mechanism 42, a working unit 43, a work confirmation unit 44, a work display unit 45, a work acceptance unit 46, and a work communication unit 47.

[0056] Based on various information stored in the work memory unit 40 and commands sent from the management device 3, the work control unit 41 (control unit) controls the work transport mechanism 42 to transport the board B to the work unit 43, and controls the work unit 43 to perform production work. The work control unit 41 of the solder printing device M2 controls the printing work unit (work unit 43) to perform solder printing work on the board B. The work control unit 41 of the component mounting devices M5, M6 controls the mounting work unit (work unit 43) to perform component mounting work on the board B on which solder has been printed.

[0057] 10, the inspection device Mi includes an inspection memory unit 50, an inspection control unit 51, an inspection transport mechanism 52, an inspection camera 53, an image acquisition unit 54, a pass / fail determination unit 55, an inspection transmission unit 56, an inspection display unit 57, an inspection reception unit 58, and an inspection communication unit 59. Based on various information stored in the inspection memory unit 50 and commands transmitted from the management device 3, the inspection control unit 51 (control unit) controls the inspection transport mechanism 52 to transport the board B and controls the inspection camera 53 to capture an image of the inspection target.

[0058] The inspection camera 53 of the first inspection device M3 captures an image of the solder printed on the board B, which is the object to be inspected. The inspection camera 53 of the second inspection device M7 captures an image of the components mounted on the board B, which is the object to be inspected. The image acquisition unit 54 acquires an image of the object to be inspected. The pass / fail judgment unit 55 judges the pass / fail of the object to be inspected based on the image of the object to be inspected. In this way, the inspection device Mi inspects the object to be inspected including the board B and judges the pass / fail of the object to be inspected. The inspection transmission unit 56 transmits the inspection results, which include the image of the object to be inspected and the result of the pass / fail judgment of the object to be inspected, to the management device 3, the confirmation device 4, and the board supply and storage device Ms, in association with the identification information of the board B, which is the object to be inspected.

[0059] 10, the management device 3 includes a management storage unit 60, a management acquisition unit 61, a work order creation unit 62, a management transmission unit 63, a management confirmation unit 64, a management display unit 65, a management reception unit 66, a management wireless communication unit 67, and a management communication unit 68. The confirmation device 4 includes a confirmation storage unit 70, a confirmation acquisition unit 71, a confirmation transmission unit 72, a confirmation display unit 73, a confirmation reception unit 74, and a confirmation communication unit 75.

[0060] Next, with reference to Fig. 10, a defective board accommodation process in which the board supplying and storing device Ms (accommodating device) accommodates a defective board will be described. The supply receiving unit 23 (acquisition unit) of the board supplying and storing device Ms acquires the inspection results from the upstream inspection device Mi. For example, the supply receiving unit 23 of the second board supplying and storing device M4 acquires the inspection results from the upstream first inspection device M3, including a pass / fail judgment on the printing state of the solder printed on the board B by the solder printing device M2. In addition, the supply receiving unit 23 of the third board supplying and storing device M8 acquires the inspection results from the upstream second inspection device M7, including a pass / fail judgment on the mounting state of the components mounted on the board B by the component mounting devices M5 and M6.

[0061] If the pass / fail determination is good, the supply control unit 21 controls the lifting mechanism 13 to position the transport mechanism 11 at the substrate transport height position, and controls the transport mechanism 11 to execute a substrate passing process in which the good substrate B is transported downstream without being stored in the magazine S (see FIG. 3). That is, if the pass / fail determination by the inspection device Mi is good, the supply control unit 21 (control unit) controls the lifting mechanism 13 so that the substrate B transported from the inspection device Mi is transported downstream of the substrate supply storage device Ms (storage device).

[0062] If the pass / fail determination is "bad," the supply control unit 21 controls the lifting mechanism 13 to position the magazine S at the substrate storage height position, and controls the carry-in mechanism 10 and the substrate transfer mechanism 15 to execute a substrate storage process to store the defective substrate B in an empty slot SL (see FIGS. 4 and 5). In other words, if the pass / fail determination by the inspection device Mi is "bad," the supply control unit 21 (control unit) controls the lifting mechanism 13 so that the substrate B carried out from the inspection device Mi is stored in an empty slot SL among the multiple slots SL. In this way, the supply control unit 21 (control unit) controls the lifting mechanism 13 based on the acquired inspection results.

[0063] 10, in the above embodiment, the supply control unit 21 of the substrate supplying and accommodating device Ms judges whether to execute the substrate passing process or the substrate accommodating process based on the pass / fail judgment of the inspection device Mi, but this judgment may be executed by the management device 3. That is, the management acquisition unit 61 (acquisition unit) of the management device 3 acquires the inspection results by the inspection device Mi, and the work command creation unit 62 creates a work command that specifies the work at the substrate supplying and accommodating device Ms (accommodating device) based on the acquired inspection results. Specifically, the work command creation unit 62 creates a passing command to execute the substrate passing process if the result of the pass / fail judgment included in the inspection result is good, and creates an accommodation command to execute the substrate accommodation process if the result is bad.

[0064] Next, the management transmission unit 63 (transmission unit) transmits the created work command to the board supply and accommodation device Ms arranged downstream of the inspection device Mi that obtained the inspection results. Specifically, the management transmission unit 63 transmits the work command to the second board supply and accommodation device M4 when the inspection device Mi is the first inspection device M3, and transmits the work command to the third board supply and accommodation device M8 when the inspection device Mi is the second inspection device M7. The supply control unit 21 (control unit) of the board supply and accommodation device Ms controls the carry-in mechanism 10, the transport mechanism 11, the carry-out mechanism 12, the lifting mechanism 13, and the board transfer mechanism 15 based on the work command (passage command, accommodation command) received by the supply receiving unit 23 (receiving unit) to perform the board passing process or the board accommodation process.

[0065] In this way, the production system 1 including the working device Mw that performs work on the board B and the inspection device Mi that inspects the inspection object including the board B is equipped with a board supplying and storing device Ms (storage device) that is provided downstream of the inspection device Mi and can store a plurality of boards B and can be raised and lowered. This makes it possible to flexibly configure a production line L that can selectively store defective boards B. The magazine S that stores the defective boards B is collected from the board supplying and storing device Ms by the automatic guided vehicle V. The collected magazine S is transported to the repair work area A by the automatic guided vehicle V. In addition, an empty magazine S is transported to the board supplying and storing device Ms by the automatic guided vehicle V (see Figures 8 and 9).

[0066] Next, with reference to Fig. 10, a confirmation process of the inspection results will be described in which an operator uses the confirmation device 4 arranged away from the production line L to confirm the inspection results by the inspection device Mi. The confirmation acquisition unit 71 (acquisition unit) of the confirmation device 4 acquires the inspection results including an image of the object to be inspected and the result of the pass / fail judgment from the inspection device Mi. When the above-mentioned defective board storage process is executed in which the board B judged to be defective by the inspection device Mi is stored in the magazine S by the board supplying and storing device Ms (storage device), the confirmation acquisition unit 71 acquires the inspection results related to the board B stored in the board supplying and storing device Ms. In other words, the confirmation acquisition unit 71 acquires only the inspection results related to the board B judged to be defective by the inspection device Mi.

[0067] The confirmation display unit 73 (display unit) displays the acquired inspection results. That is, the confirmation display unit 73 displays identification information of the board B, the pass / fail judgment result, the details of the defect (solder smear, solder seepage, misalignment of a component, absence of a component, etc.), an image of the defective part (an image of the object to be inspected), etc. The worker makes a pass / fail judgment by looking at the inspection results displayed on the confirmation display unit 73. The confirmation receiving unit 74 (receiving unit) receives the pass / fail judgment by the worker, that is, a pass / fail judgment made by visual inspection of the inspection results displayed on the confirmation display unit 73 (display unit).

[0068] 10, when confirmation receiving unit 74 receives that substrate B is good based on the visual judgment, confirmation sending unit 72 transmits an unloading command to unload substrate B downstream to the substrate supplying and accommodating device Ms accommodating substrate B. That is, confirmation sending unit 72 (transmitting unit) transmits a command (unloading command) to unload substrate B, for which confirmation receiving unit 74 (accepting unit) has received that substrate B has been judged to be good, downstream from substrate supplying and accommodating device Ms (accommodating device).

[0069] Based on the unloading command received by supply receiving unit 23 (receiving unit), supply control unit 21 (control unit) of substrate supply storage device Ms controls unloading mechanism 12, lifting mechanism 13, and substrate ejection mechanism (substrate transfer mechanism 15) to execute an unloading process for unloading the corresponding substrate B from magazine S to a downstream device (see Figs. 6 and 7). Work on the unloaded substrate B is resumed by the downstream device.

[0070] 10, a management acquisition unit 61 of the management device 3 acquires the inspection results from the inspection device Mi, and stores the inspection results in a management storage unit 60. The stored inspection results are used as reference information for quality control (traceability) of mounted boards and for repair work of defective boards.

[0071] The confirmation sending unit 72 of the confirmation device 4 also sends the carry-out command to the management device 3. When the management acquisition unit 61 (acquisition unit) of the management device 3 acquires the carry-out command, it adds information that the board B has been visually judged to be good to the inspection results of the corresponding board B stored in the management memory unit 60. That is, the inspection results of the board B that has been judged to be defective by automatic judgment by the inspection device Mi are stored with information that the board has been visually judged to be good by an operator working at a location away from the production line L.

[0072] In this way, the management device 3 includes a management storage unit 60 (storage unit) that stores the inspection results acquired from the inspection device Mi, and when the confirmation receiving unit 74 (receiving unit) of the checking device 4 receives a notification that the pass / fail determination is good, the management device 3 updates the inspection results for the board B stored in the management storage unit 60. This ensures that information used for quality control and repair work is correctly updated.

[0073] In this way, a production system including a working device Mw that performs work on a substrate B and an inspection device Mi that inspects inspection objects including a substrate B includes a substrate supply and storage device Ms (storage device) that is capable of temporarily storing a plurality of substrates B and is arranged downstream of the inspection device Mi, a management device 3 that manages at least the substrate supply and storage device Ms, and a confirmation device 4 for confirming the inspection results by the inspection device Mi.

[0074] The confirmation device 4 includes at least a confirmation acquisition unit 71 (acquisition unit) that acquires inspection results for the boards B accommodated in the board supplying and accommodating device Ms, a confirmation display unit 73 (display unit) that displays the acquired inspection results, a confirmation reception unit 74 (reception unit) that accepts a visual pass / fail judgment of the inspection results displayed on the confirmation display unit 73, and a confirmation transmission unit 72 that transmits a command to transport the boards B that the confirmation reception unit 74 has accepted as being good to the downstream of the board supplying and accommodating device Ms. This allows an operator to make a visual judgment from a location away from the production line L and easily resume work on the boards B that were determined to be good.

[0075] 10, a re-introduction process in which a board B that has been removed from the production line L as defective and has undergone repair work is re-introduced into the production line L, and a production work process for the repaired board B. A board B that has been determined to be defective by the inspection device Mi is stored in a magazine S by a board supply and storage device Ms (storage device), removed from the production line L, and transported to a repair work area A by an automatic guided vehicle V.

[0076] In the repair work area A, a worker performs repair work on a defective board B, such as removing solder, correcting misalignment of components, and removing the defective components, and inputs the details of the repair work into a confirmation device 4 installed in the repair work area A. In this way, a confirmation memory unit 70 (memory unit) of the confirmation device 4 stores work history information including repair work history information relating to the history of repair work performed on a board B removed from the production line L in association with the identification information of the board B. In addition, a confirmation transmission unit 72 (transmission unit) of the confirmation device 4 transmits the work history information to the management device 3, the board supply and storage device Ms, the working device Mw, and the inspection device Mi.

[0077] 10, the board B to be re-introduced into the production line L after the repair work is stored in a magazine S and transported to the production line L by an automated guided vehicle V. The magazine S transported by the automated guided vehicle V is handed over to a board supplying and storing device Ms (insertion device) that is arranged upstream of a working device Mw or an inspection device Mi that performs production work on the board B to be re-introduced. In this way, the automated guided vehicle V receives the magazine S that contains the board B removed by the board supplying and storing device Ms (storage device), or hands over the magazine S that contains the board B to be re-introduced to the board supplying and storing device Ms (insertion device).

[0078] The board supplying and storing device Ms (insertion device) re-inserts the repaired board B that was stored in the magazine S into the production line L. The position of the board supplying and storing device Ms that re-inserts the board may be upstream of the working device Mw, and may be the first board supplying and storing device M1, which is a board insertion device provided at the beginning of the production line L. When re-inserting the board, the identification information acquisition unit 16 of the board supplying and storing device Ms reads the identification mark attached to the board and acquires the identification information associated with the board. The acquired identification information is transmitted to the management device 3, the downstream working device Mw, and the inspection device Mi.

[0079] In FIG. 10, the work confirmation unit 44 (confirmation unit) of the operating device Mw that receives the re-introduced board B confirms whether the board B has been worked on based on the identification information acquired by the identification information acquisition unit 16 and the work history information on the work history of the board B associated with the identification information transmitted from the confirmation device 4. In the case of the board B for which the necessary work has not been performed by the operating device Mw, the work control unit 41 (control unit) controls the operating unit 43 to execute the necessary work. In the case of the board B for which work has been performed, the work control unit 41 (control unit) of the operating device Mw controls the work transport mechanism 42 to transport the board B downstream. In other words, the operating device Mw transports the board B that has been confirmed as having been worked on by the work confirmation unit 44 downstream without performing any work on it.

[0080] 10, in the above-described embodiment, the work confirmation unit 44 of the operating device Mw confirms whether or not work is required for the re-introduced board B, but this confirmation may be performed by the management device 3. That is, the management confirmation unit 64 (confirmation unit) of the management device 3 confirms, based on the identification information and the work history information, whether the board B that has been re-introduced into the production line L and carried into the operating device Mw has already been worked on.

[0081] The work command creation unit 62 creates a work command to perform the necessary work if the work has not been performed, and creates a pass command to transport downstream without performing the work if the work has been performed, and the management transmission unit 63 transmits the created command to the working device Mw. That is, the management device 3 transmits a command (pass command) to the working device Mw that performed work on the board B confirmed by the management confirmation unit 64 as having been performed to transport the board downstream without performing the work.

[0082] In this way, the production system 1, which includes at least one working device Mw that performs work on the board B, is equipped with a storage device (substrate supplying and storing device Ms) that extracts the board B from the production line L including the working device Mw, an input device (substrate supplying and storing device Ms) that re-introduces the extracted board B into the production line L, an identification information acquisition unit 16 that reads the identification mark attached to the board B and acquires the identification information associated with the board, and a confirmation unit (work confirmation unit 44, management confirmation unit 64) that confirms whether the board B has been worked on based on the identification information acquired by the identification information acquisition unit 16 and work history information regarding the work history of the board B associated with the identification information.

[0083] Then, the working device Mw conveys the board B downstream without performing any work on the board B that has been confirmed as having been worked on by the confirmation unit (the work confirmation unit 44, the management confirmation unit 64). This makes it possible to flexibly configure the production line L in which work can be resumed on the board B that has been re-introduced after the repair work.

[0084] Next, a method for accommodating a defective board by the board supplying and storing device Ms provided in the production system 1 will be described with reference to the flow of Fig. 11. First, the supply receiving unit 23 (receiving unit) of the board supplying and storing device Ms acquires the inspection result of the board B carried in from the upstream inspection device Mi (ST1). Next, if the inspection result of the board B is defective (No in ST2), the supply control unit 21 executes a board storage process to store the board B in an empty slot SL of the magazine S (ST3) (see Figs. 4 and 5).

[0085] Furthermore, if the inspection result of substrate B is good (Yes in ST2), the supply control unit 21 executes a substrate passing process to transport substrate B downstream (ST4) (see FIG. 3). This allows only defective substrates B to be accommodated in the magazine S. When the substrate accommodation process (ST3) or substrate passing process (ST4) is completed, the process returns to (ST1) and the inspection result of the next substrate B carried in is obtained.

[0086] Next, a method for confirming the inspection results by the confirmation device 4 provided in the production system 1 will be described with reference to the flow of Fig. 12. First, the confirmation acquisition unit 71 (acquisition unit) of the confirmation device 4 acquires the inspection results including an image of the object to be inspected and the result of the pass / fail judgment from the inspection device Mi (ST11). If the inspection result is good (Yes in ST12), the target substrate B has already been transported to a downstream device without being accommodated in the substrate supply / accommodation device Ms, so nothing is done (return to ST11). If the inspection result is bad (No in ST12), the confirmation display unit 73 (display unit) displays the inspection result (ST13).

[0087] If the worker visually checks the inspection results, and the confirmation reception unit 74 (reception unit) receives a message that the visual inspection result is defective (No in ST14), the process returns to ST11 without taking any action since the target substrate B is already accommodated in the substrate supply and accommodation device Ms. If the confirmation reception unit 74 (reception unit) receives a message that the visual inspection result is good (Yes in ST14), the confirmation transmission unit 72 (transmission unit) transmits an unloading command to the substrate supply and accommodation device Ms that is temporarily accommodating the target substrate B (ST15), and the process returns to ST11.

[0088] In addition, when the target substrate B is waiting for a command in the loading mechanism 10 of the substrate supply and storage device Ms, if the inspection result is good (Yes in ST12), a passing command is sent to execute the substrate passing process, and if the visual inspection result is bad (No in ST14), a storage command is sent to execute the substrate storage process.

[0089] Next, a method for unloading a good board by unloading a board B temporarily stored in a board supply storage device Ms provided in the production system 1 downstream will be described with reference to the flow of Fig. 13. When the supply receiving unit 23 (receiving unit) of the board supply storage device Ms receives an unloading command (ST15) transmitted from the confirmation device 4 by the above-mentioned method for confirming the inspection results (Yes in ST21), the supply control unit 21 executes a board unloading process for unloading the corresponding board B that was temporarily stored downstream (ST22) (see Figs. 6 and 7). This allows the operation to be resumed for the board that was automatically judged to be defective by the inspection device Mi but was visually judged to be good.

[0090] 14, a method of production work in the working apparatus Mw for a re-input board after repair work, which is a board B that has been removed from the production line L as defective and then re-input into the production line L after repair work, will be described. Here, a component mounting method for the re-input board by the component mounting apparatuses M5 and M6, which are the working apparatus Mw, will be described as an example. When the re-input board is carried into the component mounting apparatuses M5 and M6 (ST31), identification information of the re-input board is acquired from the identification information acquisition unit 16 (ST32), and work history information of the re-input board is acquired from the confirmation apparatus 4 (ST33).

[0091] Next, the work confirmation unit 44 judges whether the target re-input board has been subjected to work by the component mounting devices M5, M6 based on the identification information and the work history information (ST34). If the work has not been performed (No in ST34), the mounting work unit (work unit 43) performs the necessary component mounting work on the re-input board (ST35), and then the re-input board is transported to the downstream device (ST36). If the work has been performed (Yes in ST34), the re-input board is transported to the downstream device without performing the component mounting work (ST36). Once the re-input board has been transported out (ST36), the process returns to (ST31) and processing is performed on the next re-input board that is transported in. This allows appropriate production work to be performed according to the re-input board B after the repair work.

[0092] Next, the configuration of the substrate accommodating device Mt arranged in the production line L will be described with reference to Figures 15 and 16. The substrate accommodating device Mt shown in Figure 16(b) shows a configuration seen from the position BB in Figure 16(a). The production line L shown in Figure 1 may be configured by replacing at least one of the second substrate supply and accommodation device M4, the third substrate supply and accommodation device M8, and the fourth substrate supply and accommodation device M10 with a substrate accommodating device Mt.

[0093] The substrate accommodating device Mt includes an input mechanism 80, a transport mechanism 81, an output mechanism 82, a rotation mechanism 84, a lifting mechanism 86, a substrate transfer mechanism 87, an identification information acquisition unit 90, a magazine transfer mechanism 92, an accommodation memory unit 93, an accommodation control unit 94, an accommodation receiving unit 95, and an accommodation communication unit 96. The substrate accommodating device Mt also includes an accommodation display unit (not shown) similar to the supply display unit 24 of the substrate supply and accommodation device Ms, and an accommodation reception unit (not shown) similar to the supply reception unit 25.

[0094] The loading mechanism 80, unloading mechanism 82, identification information acquisition unit 90, storage memory unit 93, storage receiving unit 95, and storage communication unit 96 provided in the substrate accommodation device Mt are similar to the loading mechanism 10, unloading mechanism 12, identification information acquisition unit 16, supply memory unit 20, supply receiving unit 23, and supply communication unit 26 provided in the substrate supply accommodation device Ms, and detailed explanations are omitted.

[0095] 15 and 16, the transport mechanism 81 of the substrate accommodating device Mt is disposed on the upper part of a transport mechanism holding member 83. The transport mechanism holding member 83 is rotated in a horizontal plane with the Z axis as the rotation axis by a rotation mechanism 84 disposed on the upper part of a lifting member 85. The rotation mechanism 84 is controlled by an accommodation control unit 94. By operating the rotation mechanism 84, the transport mechanism 81 rotates between a transport direction (X direction) (FIG. 17(a)) in which the pair of conveyors face the same direction as the carry-in mechanism 80 and the carry-out mechanism 82, and a storage direction (Y direction) (FIG. 17(b)) perpendicular to the transport direction.

[0096] The lifting mechanism 86 is controlled by the accommodation control unit 94. By operating the lifting mechanism 86, the transport mechanism 81 and the rotation mechanism 84 are raised and lowered up and down (in the Z direction) together with the lifting member 85 (arrow e2 in FIG. 18(b)). When the transport mechanism 81 receives a substrate from the carry-in mechanism 80 or delivers a substrate to the carry-out mechanism 82, the lifting mechanism 86 positions the conveyor of the transport mechanism 81 at a substrate transport height position where the height position of the conveyor of the transport mechanism 81 coincides with the conveyors of the carry-in mechanism 80 and the carry-out mechanism 82 (the state in FIGS. 15 and 16).

[0097] 15 and 16, a magazine placement section 91 having a magazine transfer mechanism 92 at its upper part is disposed on the front side of the substrate accommodating device Mt. The substrate transfer mechanism 87 is disposed on the upper part of the lifting member 85, at a position facing the magazine transfer mechanism 92 across the transport mechanism 81. The substrate transfer mechanism 87 is configured to include a pusher 88 that extends in the accommodation direction (Y direction) and has at its end a contact part 88a that contacts the upstream end of the substrate, and a pusher movement mechanism 89 that moves the pusher 88 in and out in the accommodation direction. The pusher movement mechanism 89 is disposed on the upper part of the lifting member 85. A magazine S having a plurality of slots SL is placed on the magazine transfer mechanism 92 with the direction of the slots SL being the accommodation direction.

[0098] The height position of the abutment portion 88a of the pusher 88 is set at a height position where it can abut against the upstream end of the substrate B placed by the transport mechanism 81 facing the storage direction and move the substrate B to an empty slot SL of the magazine S placed on the magazine transfer mechanism 92 (see FIG. 19(b)). By operating the lifting mechanism 86, the substrate transfer mechanism 87 moves up and down (in the Z direction) while the relative height relationship between the abutment portion 88a and the substrate B placed on the transport mechanism 81 remains unchanged (see FIG. 18). That is, the lifting mechanism 86 raises and lowers the position of the magazine S placed on the magazine transfer mechanism 92 of the magazine placement portion 91 relative to the substrate transfer mechanism 87.

[0099] The magazine transfer mechanism 92 includes rollers, conveyors, and the like that move the magazine S in the storage direction (Y direction), and is controlled by a storage control unit 94. By operating the magazine transfer mechanism 92, the magazine S moves in the storage direction (arrow f2 in FIG. 20(b)).

[0100] Next, with reference to Figures 17 to 19, a substrate accommodation process in which the substrate accommodation device Mt accommodates the substrate B in the magazine S will be described. In Figure 17(a), the accommodation control unit 94 positions the transport mechanism 81 at the substrate transport height position, and operates the conveyors of the carry-in mechanism 80 and the transport mechanism 81 to transport the substrate B carried in from the upstream device to the transport mechanism 81 (arrow e1, Figure 18(a)). In Figure 18(b), the accommodation control unit 94 then operates the lift mechanism 86 to lift the lift member 85 and raise the transport mechanism 81 to the substrate transfer height position (arrow e2).

[0101] 17(b), the accommodation control unit 94 then operates the rotation mechanism 84 to rotate the transport mechanism 81 on which the substrate B is placed in the accommodation direction (arrow e3, FIG. 19(a)). In FIG. 19(b), the accommodation control unit 94 then operates the pusher moving mechanism 89 to move the pusher 88 toward the magazine S and push the upstream end of the substrate B with the contact portion 88a to move the substrate B to the accommodation position in the slot SL (arrow e4).

[0102] In this way, the substrate accommodating device Mt is an accommodating device that includes a lifting mechanism 86, an accommodation control unit 94 (control unit) that controls the lifting mechanism 86, a transport mechanism 81 that transports the substrate B received from upstream downstream and lifts and lowers it with the lifting mechanism 86, a magazine S having multiple slots SL, and a substrate transfer mechanism 87 that transfers the substrate B received from upstream to any one of the multiple slots SL of the magazine S, and is capable of accommodating multiple substrates B. The accommodation control unit 94 controls the lifting mechanism 86 so that the substrate B received from upstream is accommodated in an empty slot SL among the multiple slots SL of the magazine S. Then, the substrate transfer mechanism 87 transfers the substrate B received from upstream to any one of the multiple slots SL of the magazine S.

[0103] In the above-described substrate accommodating device Mt, the transport mechanism 81 and the substrate transfer mechanism 87 arranged on the upper part of the lifting member 85 are raised and lowered by the lifting mechanism 86 to accommodate the substrate B in the vacant slot SL of the magazine S, but this configuration is not limited to this. For example, the substrate accommodating device Mt may raise and lower the magazine S on which the magazine placement section 91 is placed, and accommodate the substrate B in the vacant slot SL by the transport mechanism 81 and the substrate transfer mechanism 87 whose height positions are fixed.

[0104] 1, including the working device Mw (solder printing device M2, component mounting devices M5, M6) and the inspection device Mi (first inspection device M3, second inspection device M7), can use the board accommodation device Mt as an accommodation device that can accommodate and lift a plurality of boards B provided downstream of the inspection device Mi. The accommodation receiving unit 95 (acquisition unit) of the board accommodation device Mt acquires the inspection results by the inspection device Mi, and the accommodation control unit 94 (control unit) controls the lifting mechanism 86, the rotation mechanism 84, and the board transfer mechanism 87 based on the inspection results so as to accommodate a defective board B in an empty slot SL. This makes it possible to flexibly construct a production line L that can selectively accommodate a defective board B.

[0105] Next, a magazine receiving process in which the automated guided vehicle Vt receives the magazine S from the substrate storage device Mt (storage device) will be described with reference to Fig. 20. The automated guided vehicle Vt, which transfers the magazine S between the substrate storage device Mt and the automated guided vehicle Vt, is equipped with a magazine moving mechanism 100 on its upper portion, which differs from the automated guided vehicle V, which is equipped with a magazine placement mechanism 33 on its upper portion and transfers the magazine S between the substrate supply storage device Ms and the automated guided vehicle Vt. The other components of the transport memory unit, transport control unit, travel mechanism, and transport wireless communication unit equipped in the automated guided vehicle Vt are the same as those of the automated guided vehicle V, and detailed description thereof will be omitted.

[0106] In Fig. 20(a), when the substrates B are accommodated in all of the slots SL of the magazine S placed on the magazine placement unit 91 of the substrate accommodation device Mt, an empty automated guided vehicle Vt not carrying a magazine S approaches the front of the substrate accommodation device Mt and moves to the front of the magazine placement unit 91 (arrow f1). In Fig. 20(b), the accommodation control unit 94 then operates the magazine transfer mechanism 92, and the transport control unit operates the magazine moving mechanism 100 to move the magazine S that was placed on the magazine placement unit 91 to the automated guided vehicle Vt (arrow f2). When the magazine S moves to the automated guided vehicle Vt, the automated guided vehicle Vt transports the magazine S containing the substrates B to a specified position (arrow f3).

[0107] The magazine delivery process for transferring the magazine S from the automated guided vehicle Vt to the substrate storage device Mt is performed in the reverse order to the magazine reception process described above. That is, the automated guided vehicle Vt carrying the magazine S moves to the front of the magazine placement section 91, and the magazine moving mechanism 100 and the magazine transfer mechanism 92 move the magazine S from the automated guided vehicle Vt to the magazine placement section 91. In this manner, the substrate storage device Mt (storage device) is equipped with the magazine transfer mechanism 92 for transferring the magazine S to and from the automated guided vehicle Vt. The magazine S is then transported by the automated guided vehicle Vt, and the magazine S is transferred between the substrate storage device Mt and the automated guided vehicle Vt.

[0108] In this way, the substrate accommodation device Mt (storage device) is equipped with a magazine transfer mechanism 92 that transfers the magazine S to and from the unmanned guided vehicle Vt that transports the magazine S. Note that the above-mentioned substrate accommodation device Mt transfers the magazine S to and from the unmanned guided vehicle Vt stopped in front of the magazine placement section 91, but is not limited to this configuration. For example, the magazine transfer mechanism 92 may move the magazine S in the transport direction (X direction), and an unmanned guided vehicle Vt having a magazine moving mechanism 100 that also moves the magazine S in the transport direction may be stopped to the side of the magazine placement section 91 to transfer the magazine S.
