Further, a drive signal and the like are output from the control device 60 to the substrate transport device 52, the backup device 54, the head unit 56, and the XY robot 58 via the input / output interface 65. The control device 60 is communicably connected to a management device (not shown), receives production data (production job) related to the production of the substrate S from the management device, and mounts the component P on the substrate S according to the received production data. I do. Here, the production data defines which component P (wafer) is mounted on the substrate S in which order in the component mounting apparatus 50, and how many substrates S on which the component P is mounted are produced. Data. The production data also includes part data that defines how many parts P (wafers) necessary for mounting are located in which wafer replenishment position (slot 32) of the magazine 30. Production data (part data) is created by an operator. Prior to production, the worker selects in advance the supply mode of the parts P of the magazine 30 and creates part data corresponding to the selected supply mode. Here, as a supply mode of the parts P, the same parts are supplied to the upper stage (upper wafer supply position) and the lower stage (lower wafer supply position) of one magazine 30, and only one of them is normally used. A mode in which parts P are supplied and parts P are supplied by switching to the other use when parts run out or an error occurs, and upper (upper wafer replenishment position) and lower (lower wafer replenishment positions) of one magazine 30 ) To supply the part P and supply the part P necessary for the next production to the other wafer supply position, the upper stage (upper wafer supply position) and the lower stage (lower wafer supply position) of the magazine 30. ) And the like are used to supply the component P.

As described above, the control device 60 of the component mounting device 50 is communicably connected to the control device 40 of the component supply device 20, and when starting production according to the production data, the component data included in the production data is included in the component data. Based on this, a control signal for instructing the supply of the necessary component P (wafer) is transmitted to the control device 40 of the component supply device 20.

The control device 60 of the component mounting device 50 moves the suction nozzle 57 to a position (component supply position) where the component P (wafer) is supplied by the component supply device 20 to suck the component P, and the sucked component P is a substrate. The head unit 56 and the XY robot 58 are controlled to be mounted at the mounting position on S. Prior to mounting the component P, the control device 60 captures the suction posture of the sucked component P with the parts camera 59, and determines whether or not the component P is normally sucked based on the obtained image. . When the control device 60 determines that the component P is normally sucked, the controller 60 performs the mounting operation of the sucked component P. When the control device 60 determines that the component P is not normally sucked, the component P is normally sucked. Until the determination is made, the recovery operation for re-sucking the new component P is performed. An error is output when the number of executions of the recovery operation reaches a predetermined number. When the aspect A is selected as the supply mode of the component P of the component supply device 20, the control device 60 transmits an error signal to the control device 40 of the component supply device 20 to switch the wafer replenishment position to be used. Instruct.

Next, the operation of the component supply apparatus 20 according to the embodiment will be described. FIG. 9 is a flowchart illustrating an example of a component supply process executed by the CPU 41 of the control device 40.

When the component supply process is executed, the CPU 41 of the control device 40 first determines whether it is in production (manufacturing the substrate S on which the component P is mounted) (S100), and determines that it is not in production. The large door locking solenoid 22a, the upper small door locking solenoid 23a, and the lower small door locking solenoid 24a are driven so that all the locks of the large door 22, the upper small door 23, and the lower small door 24 are released. Control is performed (S110 to S130), and the component supply process is terminated. As a result, the large door 22 can be opened and the magazine 30 can be replaced, or a changeover can be performed in which a part P (wafer) necessary for the next production is accommodated in the magazine 30.

When the CPU 41 determines that the large door 22 is in production, the CPU 41 drives and controls the large door locking solenoid 24a so that the large door 22 is locked (S140). Thus, the operator cannot open the large door 22 and cannot take out the magazine 30. Then, the CPU 41 determines whether or not the component supply mode selected by the operator is either mode A or mode B in which only one of the upper and lower wafer replenishment positions of the magazine 30 is used (S150). . If the CPU 41 determines that the component supply mode is either mode A or mode B, the CPU 41 determines whether the upper stage (upper wafer replenishment position) of the magazine 30 is in use (S160). The determinations in S150 and S160 can be made based on a component supply instruction transmitted from the control device 60 of the component mounting apparatus 50. When the CPU 41 determines that the component supply mode is either mode A or mode B and the upper stage of the magazine 30 is in use, the CPU 41 drives the upper stage door locking solenoid 23a so that the upper stage door 23 is locked. While controlling (S170), the lower stage door lock solenoid 24a is driven and controlled so that the lower door 24 is unlocked (S180). Thus, even during production, the operator can replenish the wafer 36 to the lower wafer replenishment position of the magazine 30 by opening the lower door 24. Then, the CPU 41 drives and controls the component supply robot 28 so that the pallet 34 on which the necessary wafers 36 are placed is pulled out from the upper stage (upper wafer replenishment position) of the magazine 30 and supplied to the component mounting apparatus 50 (S190). Then, the component supply process is terminated.

On the other hand, the CPU 41 determines that the component supply mode is either mode A or mode B, and the upper stage (upper wafer supply position) of the magazine 30 is not in use, that is, the lower stage (lower wafer supply position) is in use. Is determined, the upper stage door lock solenoid 23a is driven and controlled so that the upper stage door 23 is unlocked (S200), and the lower stage door lock solenoid 24a is operated so that the lower stage door 24 is locked. Drive control is performed (S210). Thus, even during production, the operator can replenish the wafer 36 to the upper wafer replenishment position of the magazine 30 by opening the upper small door 23. Then, the CPU 41 drives and controls the component supply robot 28 so that the pallet 34 on which the necessary wafers 36 are placed is pulled out from the lower stage (lower wafer supply position) of the magazine 30 and is supplied to the component mounting apparatus 50 (S220). Then, the component supply process is terminated.

When the CPU 41 determines that the component supply mode is neither mode A nor mode B, that is, determines that the component supply mode is mode C using both of the upper and lower wafer replenishment positions of the magazine 30, The upper small door locking solenoid 23a and the lower small door locking solenoid 24a are driven and controlled so that the upper small door 23 and the lower small door 24 are locked together (S230, S240). As a result, the operator cannot replenish the wafer 36 during production. Then, the CPU 41 pulls out the pallet 34 on which the necessary wafers 36 are placed from both the upper and lower stages of the magazine 30 (upper wafer replenishment position and lower wafer replenishment position) and supplies them to the component mounting apparatus 50. Is controlled (S250), and the component supply process is terminated.

According to the component supply device 20 of the embodiment described above, in addition to the large door 22 for placing the magazine 30 on the magazine holding unit 26 and taking it out of the magazine holding unit 26, the upper slot group of the magazine 30 is provided. An upper small door 23 capable of replenishing a wafer (upper wafer replenishment position) and a lower small door 24 capable of replenishing a wafer in a lower slot group (lower wafer replenishment position) of the magazine 30 are provided. As a result, while the component P (wafer) is being supplied by the pallet 36 accommodated in a part of the slots 32 of one magazine 30, the component P can be replenished to the other slots 32. When the upper stage of the magazine 30 is in use, the upper door 23 is locked and the lower door 24 is unlocked. When the lower part of the magazine 30 is in use, the upper door 23 is unlocked. Since the lock is released and the lower door 24 is locked, it is possible to ensure safety when the wafer 36 is replenished during production. Further, a slot between the upper slot group and the lower slot group of the magazine 30 is set as an unused slot, and the partition plate 32 is accommodated therein. As a result, the operator cannot reach from the upper small door 23 to the lower slot group, and cannot reach from the lower small door 24 to the upper slot group. The safety when replenishing can be further improved. In addition, since the

small doors

23 and 24 are provided on the front surface of the large door 22, the space can be used more effectively and the apparatus can be used more effectively than when the large door 22 and the

However, the present invention is not limited to this, and when the component supply mode is a mode C in which both of the upper and lower wafer replenishment positions of the magazine 30 are used, the intermediate slot is used for supplying wafers (components). It may be used.

In the component supply apparatus 20 of the embodiment, when the component supply mode is the mode A or mode B in which only one of the upper and lower wafer supply positions of the magazine 30 is used, it corresponds to the unused wafer supply position. The lock of the small door (the lower door 24 when the upper wafer supply position is in use and the upper door 23 when the lower wafer supply position is in use) is released. The small door may be unlocked on condition that the partition plate 38 is installed in the unused slot of the magazine 30. In this case, a sensor for detecting whether or not the partition plate 38 is installed in the unused slot of the magazine 30 may be provided.

In the component supply apparatus 20 of the embodiment, the two

small doors

23 and 24 that can replenish the wafer 36 are provided in the upper slot group and the lower slot group of the magazine 30 respectively. However, the present invention is not limited to this.
