As shown in fig. 7, there are cases where the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13 are stored in the storage device 9 in a mixed state. For example, during the transition from the state where only the suction nozzle 4 provided with the identification code 13 is used to the state where the suction nozzle 4 provided with the identification code 13 is used, there is a possibility that the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13 are mixed in the storage device 9. When the operator sets the suction nozzle 4 in the storage device 9, both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13 may be stored in the storage device 9. The detecting device 8 detects whether or not the identification code 13 is provided for each of the plurality of suction nozzles 4 stored in the storing device 9.
Fig. 8 is a diagram for explaining a detection process performed by the detection device 8 according to the embodiment. The detecting means 8 detect whether the suction nozzle 4 is provided with an identification code 13. The identification code 13 contains identification data of the suction nozzle 4. In the case where the suction nozzle 4 is provided with the identification code 13, the detection means 8 detects the identification data of the suction nozzle 4.
When detecting whether the recognition code 13 is provided to the suction nozzle 4, the suction nozzle 4 stored in the storage device 9 is mounted on the shaft 5S. After the suction nozzle 4 is mounted on the shaft 5S, the suction nozzle moving device 6 and the head moving device 7 are driven so that the 1 st main body 42 of the suction nozzle 4 and the detecting device 8 face each other with a gap.
After the 1 st main body 42 of the suction nozzle 4 and the detection device 8 are opposed to each other with a gap therebetween, the suction nozzle moving device 6 rotates the suction nozzle 4 in the θz direction. When the identification code 13 is disposed in the recess 42A of the 1 st main body 42, the identification code 13 faces the detection device 8 during rotation of the suction nozzle 4. The identification code 13 is opposed to the detection device 8, and the detection device 8 can detect the identification code 13. When the identification code 13 is not disposed in the recess 42A of the 1 st main body 42, the detection device 8 does not detect the identification code 13. Thereby, the detection device 8 can detect whether the identification code 13 is provided in the suction nozzle 4.
The detecting device 8 sequentially detects the plurality of suction nozzles 4 stored in the storing device 9. When detecting whether the identification code 13 is provided on the 1 st nozzle 4A received in the 1 st slot 14A, the 1 st nozzle 4A received in the 1 st slot 14A is mounted on the shaft 5S. The detecting device 8 detects whether the 1 st nozzle 4A accommodated in the 1 st slot 14A is provided with the identification code 13. The 1 st suction nozzle 4A, which has finished the detection process by the detection device 8, returns to the 1 st slot 14A. The detection data of the detection device 8 is acquired by the detection data acquisition unit 21. The determination unit 23 determines whether the identification code 13 is provided in the 1 st suction nozzle 4A based on the detection data acquired by the detection data acquisition unit 21 (step S2).
In step S2, when it is determined that the 1 st nozzle 4A is provided with the identification code 13 (step S2: yes), the determination unit 23 associates the identification data of the 1 st nozzle 4A included in the identification code 13 with the 1 st slot 14A in which the 1 st nozzle 4A provided with the identification code 13 is stored in the identification data storage unit 28 (step S3).
In step S2, when it is determined that the 1 st nozzle 4A is not provided with the identification code 13 (step S2: NO), the determination unit 23 stores the 1 st slot 14A in which the 1 st nozzle 4A is not provided with the identification code 13 in the identification data storage unit 28 (step S4).
In the embodiment, the suction nozzle 4 accommodated in the 1 st slot 14A is provided with the identification code 13. Therefore, the determination unit 23 associates the identification data of the 1 st nozzle 4A with the 1 st slot 14A in which the 1 st nozzle 4A is housed, and stores the data in the identification data storage unit 28.
The processing of steps S1, S2, S3, and S4 is performed for the suction nozzles 4 accommodated in the 2 nd, 3 rd, 4 th, 5 th, 6 th, 7 th, and 8 th slots 14B, 14C, 14D, 14F, 14G, and 14H, respectively.
As shown in fig. 7, in the embodiment, the recognition code 13 is provided to the suction nozzle 4 housed in the 1 st slot 14A, the 2 nd slot 14B, the 4 th slot 14D, the 6 th slot 14F, and the 7 th slot 14G, respectively. Therefore, the determination unit 23 associates and stores the identification data of the nozzle 4 provided with the identification code 13 with the 1 st slot 14A, 2 nd slot 14B, 4 th slot 14D, 6 th slot 14F, and 7 th slot 14G in which the nozzle 4 provided with the identification code 13 is stored in the identification data storage unit 28, respectively.
As shown in fig. 7, in the embodiment, the recognition code 13 is not provided to the suction nozzles 4 respectively housed in the 3 rd slot 14C, the 5 th slot 14E, and the 8 th slot 14H. Therefore, the determination unit 23 stores the 3 rd slot 14C, the 5 th slot 14E, and the 8 th slot 14H of the suction nozzle 4 in which the identification code 13 is not provided, in the identification data storage unit 28, respectively.
The required time calculation section 26 calculates the required time required for mounting the electronic component C on the substrate P using only the suction nozzle 4 provided with the identification code 13, based on the determination data of the determination section 23 and the production program stored in the production program storage section 29. The required time calculation unit 26 calculates the required time required for mounting the electronic component C on the board P using both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13, based on the determination data of the determination unit 23 and the production program stored in the production program storage unit 29 (step S5).
As shown in fig. 7, in the embodiment, the number of the suction nozzles 4 provided with the identification code 13 is 5. The total number of nozzles 4 provided with the identification code 13 and nozzles 4 not provided with the identification code 13 is 8. The required time calculation section 26 calculates the required time required for mounting the electronic component C on the substrate P using the 5 nozzles 4 provided with the identification code 13, and the required time required for mounting the electronic component C on the substrate P using the 8 nozzles 4.
In general, the time required in the case of using 8 suction nozzles 4 is shorter than that in the case of using 5 suction nozzles 4. That is, the productivity (throughput) of the electronic apparatus in the case of using 8 nozzles 4 is higher than that in the case of using 5 nozzles 4.
The notification control unit 27 causes the notification device 11 to notify the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13. The notification control unit 27 also causes the notification device 11 to notify the required time calculated by the required time calculation unit 26 (step S6).
Fig. 9 and 10 are diagrams each showing the notification device 11 according to the embodiment. In the example shown in fig. 9 and 10, the notification device 11 is a display device.
As shown in fig. 9, the notification control unit 27 associates the identification data of the suction nozzle 4 provided with the identification code 13 with the slot 14 in which the suction nozzle 4 provided with the identification code 13 is housed, and displays the associated data on the notification device 11. The notification control unit 27 causes the notification device 11 to display the slot 14 in which the suction nozzle 4, which is not provided with the identification code 13, is housed. The notification control unit 27 causes the notification device 11 to display the type of the suction nozzle 4. By checking the notification data outputted from the notification device 11, the operator can check the number of the suction nozzles 4 provided with the identification code 13, the type of the suction nozzles 4 provided with the identification code 13, and the slot 14 in which the suction nozzles 4 provided with the identification code 13 are accommodated.
As shown in fig. 10, the notification control section 27 causes the notification device 11 to display the required time required to mount the electronic component C on the substrate P using the 5 nozzles 4 provided with the identification code 13, and the required time required to mount the electronic component C on the substrate P using the 8 nozzles 4. By checking the notification data outputted from the notification device 11, the operator can compare and study the productivity in the case of using 5 nozzles 4 provided with the identification code 13 and the productivity in the case of using 8 nozzles 4.
Based on the notification data output from the notification device 11, the worker decides whether or not to use the suction nozzle 4 provided with the identification code 13 preferentially over the suction nozzle 4 not provided with the identification code 13. That is, the operator examines the number of the suction nozzles 4 provided with the identification code 13, the kind of the suction nozzle 4 provided with the identification code 13, and the required time, and decides whether or not to use the suction nozzle 4 provided with the identification code 13 preferentially over the suction nozzle 4 not provided with the identification code 13.
The worker determines whether to mount the electronic component C using only the suction nozzle 4 provided with the identification code 13 or to mount the electronic component C using both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13, in consideration of the suction nozzle management, traceability management, and productivity of the electronic apparatus. After determining the suction nozzle 4 used for mounting the electronic component C, the operator operates the input device 10.
In the case where the electronic component C is mounted using only the suction nozzle 4 provided with the identification code 13, the operator operates the input device 10 in the 1 st operation mode. When the electronic component C is mounted using both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13, the operator operates the input device 10 in the 2 nd operation mode.
By operating the input device 10 in the 1 st operation mode, 1 st input data is generated. By operating the input device 10 in the 2 nd operation mode, the 2 nd input data is generated. The 1 st input data is input data indicating that the electronic component C is mounted using only the suction nozzle 4 provided with the identification code 13. The 2 nd input data is input data indicating that the electronic component C is mounted using both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13.
The input data acquisition unit 22 acquires input data generated in the input device 10 (step S7).
The priority instruction unit 24 determines whether or not to preferentially use only the suction nozzle 4 provided with the identification code 13 based on the input data acquired by the input data acquisition unit 22. That is, the priority instruction unit 24 determines whether the input data acquired by the input data acquisition unit 22 is the 1 st input data or the 2 nd input data (step S8).
When it is determined in step S8 that only the suction nozzle 4 provided with the identification code 13 is preferentially used (yes in step S8), the priority instruction unit 24 outputs a priority instruction to preferentially use the suction nozzle 4 provided with the identification code 13 over the suction nozzle 4 not provided with the identification code 13 (step S9).
When the priority command is output from the priority command unit 24, the operation command unit 25 outputs an operation command for controlling the mounting head 5 based on the priority command and the production program stored in the production program storage unit 29 (step S10).
In step S8, when it is determined that not only the suction nozzle 4 provided with the identification code 13 is preferentially used (NO in step S8), the priority instruction unit 24 does not output a priority instruction. The operation command unit 25 outputs an operation command for controlling the mounting head 5 based on the production program stored in the production program storage unit 29 (step S11).
Fig. 11 is a diagram schematically showing the mounting head 5 when outputting a priority instruction according to the embodiment. Fig. 12 is a diagram schematically showing the mounting head 5 when no priority instruction is output according to the embodiment.
As shown in fig. 11, in the case of outputting a priority instruction, only the suction nozzle 4 provided with the identification code 13 is mounted on the mounting head 5. The mounting head 5 mounts the electronic component C on the substrate P using 5 suction nozzles 4 provided with the identification code 13.
As shown in fig. 12, when a priority instruction is output, both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13 are mounted on the mounting head 5. The mounting head 5 mounts the electronic component C on the substrate P using 8 suction nozzles 4.
[ computer System ]
Fig. 13 is a block diagram illustrating a computer system 1000 according to an embodiment. The control device 12 described above includes a computer system 1000. The computer system 1000 includes a processor 1001 such as CPU (Central Processing Unit), a main memory 1002 including a nonvolatile memory such as ROM (Read Only Memory) and a volatile memory such as RAM (Random Access Memory), a memory 1003, and an interface 1004 including an input/output circuit. The functions of the control device 12 are stored in the memory 1003 as a computer program. The processor 1001 reads a computer program from the memory 1003, expands the computer program in the main memory 1002, and executes the above-described processing according to the computer program. In addition, the computer program may be transmitted to the computer system 1000 via a network.
According to the above-described embodiments, the computer program can cause the computer system 1000 to execute the following program: it is detected whether or not the identification code 13 is provided for each of the plurality of nozzles 4 provided in the mounting head 5 for mounting the electronic component C on the substrate P, and the nozzle 4 provided with the identification code 13 is preferentially used over the nozzle 4 not provided with the identification code 13.
[ Effect ]
As described above, according to the embodiment, the priority instruction unit 24 is provided, and the priority instruction unit 24 outputs a priority instruction to use the suction nozzle 4 provided with the identification code 13 preferentially over the suction nozzle 4 not provided with the identification code 13 based on the detection data of the detection device 8. In the electronic component mounting apparatus 1, in the case where the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13 coexist, if the suction nozzle 4 not provided with the identification code 13 is used, it may be difficult to perform suction nozzle management or traceability management. According to the embodiment, when the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13 are present in a mixed manner, the suction nozzle 4 provided with the identification code 13 is preferentially used, and therefore, suction nozzle management or traceability management can be performed along the field.
The suction nozzle management is to manage the number of times the suction nozzle 4 is used (the number of suctions). The deterioration state of each of the plurality of nozzles 4 is managed by the nozzle management. The traceability management is to manage the suction nozzles 4 used in the production of the electronic equipment. Through traceability management, the suction nozzle 4 used in the production of the electronic device is determined. The electronic component C is mounted only by the suction nozzle 4 provided with the identification code 13, whereby suction nozzle management or traceability management is smoothly performed.
The priority command unit 24 outputs a priority command based on the input data generated in the input device 10. For example, there may occur a case where suction nozzle management or traceability management is important, and a case where improvement in productivity of electronic devices is important. When the suction nozzle management or the traceability management is important, the operator input device 10 operates to output a priority instruction. Accordingly, the electronic component C is mounted on the board P using only the suction nozzle 4 provided with the identification code 13, and therefore suction nozzle management or traceability management can be performed on site. In the case where improvement in productivity of the electronic apparatus is important, the operator operates the input device 10 without outputting a priority instruction. Thus, the electronic component C is mounted on the substrate P using both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13, and thus productivity of the electronic apparatus is improved.
The suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13 are notified by the notification device 11. The notification device 11 notifies the time required for mounting the electronic component C on the board P using only the suction nozzle 4 provided with the identification code 13 and the time required for mounting the electronic component C on the board P using both the suction nozzle 4 provided with the identification code 13 and the suction nozzle 4 not provided with the identification code 13. Thus, a judgment reference of whether to output a priority instruction is provided to the operator. The operator can appropriately determine whether to output a priority instruction based on the notification data output from the notification device 11, and can operate the input device 10.
Other embodiments
In the above-described embodiment, when the priority instruction is output, the electronic component C is mounted by the 5 nozzles 4 provided with the identification code 13, and when the priority instruction is not output, the electronic component C is mounted by the 5 nozzles 4 provided with the identification code 13 and the 3 nozzles 4 not provided with the identification code 13. The priority instructions may include a 1 st priority instruction using only the suction nozzle 4 provided with the identification code 13, and a 2 nd priority instruction using a specific number of suction nozzles 4 provided with the identification code 13 and suction nozzles 4 not provided with the identification code 13. For example, in the case of outputting the 2 nd priority instruction, the mounting of the electronic component C is performed by the 5 suction nozzles 4 provided with the identification code 13 and the 1 suction nozzle 4 not provided with the identification code 13.
In the above embodiment, the priority command unit 24 outputs the priority command based on the input data generated in the input device 10. The priority instruction unit 24 may be configured to: based on not the input data of the input device 10 but the detection data of the detection device 8, a priority instruction to preferentially use only the suction nozzle 4 provided with the identification code 13 is output.
In the above embodiment, the identification code 13 includes an RFID tag. The identification code 13 may comprise a two-dimensional bar code. The detection means 8 may also comprise a bar code reader.
