The detection device 8 detects whether the identification code 13 is provided on the suction nozzle 4. The identification code 13 contains identification data of the suction nozzle 4. In case the suction nozzle 4 is provided with an identification code 13, the detection means 8 detect the identification data of the suction nozzle 4.
When detecting whether or not the identification code 13 is provided to the suction nozzle 4, the suction nozzle 4 stored in the storage device 9 is attached to the shaft 5S. After the suction nozzles 4 are attached to the shaft 5S, the nozzle transfer device 6 and the head transfer device 7 are driven so that the 1 st body portions 42 of the suction nozzles 4 face the detection device 8 with a gap therebetween.
After the 1 st body 42 of the suction nozzle 4 and the detection device 8 face each other with a gap therebetween, the suction nozzle moving device 6 rotates the suction nozzle 4 in the θ Z direction. When the identification code 13 is disposed in the recess 42A of the 1 st body 42, the identification code 13 faces the detection device 8 during rotation of the suction nozzle 4. The detection device 8 can detect the identification code 13 by the identification code 13 facing the detection device 8. When the identification code 13 is not arranged in the recess 42A of the 1 st 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 on the suction nozzle 4.
The detection device 8 sequentially detects the plurality of suction nozzles 4 stored in the storage device 9. When detecting whether the identification code 13 is set in the 1 st nozzle 4A stored in the 1 st slot 14A, the 1 st nozzle 4A stored in the 1 st slot 14A is attached to the shaft 5S. The detection 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 nozzle 4A having 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 acquiring unit 21. The determination unit 23 determines whether or not the identification code 13 is provided to the 1 st nozzle 4A based on the detection data acquired by the detection data acquisition unit 21 (step S2).
When it is determined in step S2 that the identification code 13 is provided to the 1 st nozzle 4A (yes in step S2), 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).
If it is determined in step S2 that the identification code 13 is not provided to the 1 st nozzle 4A (no in step S2), the determination unit 23 stores the 1 st slot 14A, which accommodates the 1 st nozzle 4A to which the identification code 13 is not provided, in the identification data storage unit 28 (step S4).
In the embodiment, the identification code 13 is provided on the suction nozzle 4 accommodated in the 1 st slot 14A. Therefore, the determination unit 23 associates the identification data of the 1 st nozzle 4A with the 1 st slot 14A accommodating the 1 st nozzle 4A and stores the identification data in the identification data storage unit 28.
The processing of the above-described steps S1, S2, S3 and S4 is executed for the nozzles 4 respectively accommodated in the 2 nd slot 14B, the 3 rd slot 14C, the 4 th slot 14D, the 5 th slot 14E, the 6 th slot 14F, the 7 th slot 14G and the 8 th slot 14H.
As shown in fig. 7, in the embodiment, the identification code 13 is provided to the suction nozzle 4 accommodated 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 the identification data of the nozzle 4 provided with the identification code 13 with 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 in which the nozzle 4 provided with the identification code 13 is accommodated, respectively, and stores the data in the identification data storage unit 28.
As shown in fig. 7, in the embodiment, the identification code 13 is not provided in the nozzle 4 accommodated in the 3 rd slot 14C, the 5 th slot 14E, and the 8 th slot 14H, respectively. Therefore, the determination unit 23 stores the 3 rd slot 14C, the 5 th slot 14E, and the 8 th slot 14H, which store the nozzle 4 not provided with the identification code 13, in the identification data storage unit 28.
The required time calculation unit 26 calculates the required time required to mount the electronic component C on the substrate P using only the nozzle 4 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. The required time calculation unit 26 calculates the required time required for mounting the electronic component C on the substrate P using both the nozzle 4 provided with the identification code 13 and the 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 codes 13 is 5. The total number of the suction nozzles 4 provided with the identification codes 13 and the suction nozzles 4 not provided with the identification codes 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 codes 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 the time required 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 the productivity (throughput) of the electronic apparatus in the case of using 5 nozzles 4.
The notification control section 27 causes the notification device 11 to notify the nozzles 4 provided with the identification codes 13 and the nozzles 4 not provided with the identification codes 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 illustrating the notification device 11 according to the embodiment. In the examples 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 nozzle 4 provided with the identification code 13 with the slot 14 in which the nozzle 4 provided with the identification code 13 is housed, and displays the data on the notification device 11. The notification control unit 27 causes the notification device 11 to display the slot 14 that accommodates the nozzle 4 not provided with the identification code 13. In addition, the notification control unit 27 causes the notification device 11 to display the type of the suction nozzle 4. The operator can confirm the number of the nozzles 4 provided with the identification codes 13, the types of the nozzles 4 provided with the identification codes 13, and the slots 14 in which the nozzles 4 provided with the identification codes 13 are accommodated by confirming the notification data output from the notification device 11.
As shown in fig. 10, the notification control unit 27 causes the notification device 11 to display the required time required for mounting the electronic component C on the substrate P using the 5 nozzles 4 provided with the identification codes 13 and the required time required for mounting the electronic component C on the substrate P using the 8 nozzles 4. The operator can compare and study the productivity when using 5 nozzles 4 provided with the identification codes 13 and the productivity when using 8 nozzles 4 by checking the notification data output from the notification device 11.
The operator determines whether or not to use the nozzle 4 provided with the identification code 13 in preference to the nozzle 4 not provided with the identification code 13 based on the notification data output from the notification device 11. That is, the operator examines the number of the nozzles 4 provided with the identification codes 13, the type of the nozzles 4 provided with the identification codes 13, and the required time, and determines whether or not to use the nozzles 4 provided with the identification codes 13 preferentially over the nozzles 4 not provided with the identification codes 13.
The operator determines whether to mount the electronic component C using only the nozzle 4 provided with the identification code 13 or to mount the electronic component C using both the nozzle 4 provided with the identification code 13 and the nozzle 4 not provided with the identification code 13, in consideration of nozzle management, traceability management, and productivity of the electronic device. The operator determines the suction nozzle 4 to be used for mounting the electronic component C, and then operates the input device 10.
When the electronic component C is mounted only using 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 nozzle 4 provided with the identification code 13 and the nozzle 4 not provided with the identification code 13.
The input data acquisition unit 22 acquires the input data generated by the input device 10 (step S7).
The priority command unit 24 determines whether or not to preferentially use only the 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 instructing unit 24 determines whether the input data acquired by the input data acquiring unit 22 is the 1 st input data or the 2 nd input data (step S8).
If it is determined in step S8 that only the nozzle 4 provided with the identification code 13 is to be used preferentially (yes in step S8), the priority command unit 24 outputs a priority command for preferentially using the nozzle 4 provided with the identification code 13 over the nozzles 4 not provided with the identification code 13 (step S9).
When the priority command is output from the priority command section 24, the operation command section 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 section 29 (step S10).
In step S8, if it is determined that not only the nozzle 4 provided with the identification code 13 is to be used with priority (no in step S8), the priority command unit 24 does not output the priority command. The action commanding part 25 outputs an action command for controlling the mounting head 5 based on the production program stored in the production program storage part 29 (step S11).
Fig. 11 is a diagram schematically showing the mounting head 5 when outputting the priority command according to the embodiment. Fig. 12 is a diagram schematically showing the mounting head 5 when the priority command is not output according to the embodiment.
As shown in fig. 11, in the case where the priority instruction is output, only the suction nozzles 4 provided with the identification codes 13 are 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 codes 13.
As shown in fig. 12, when the priority command is output, both the suction nozzles 4 provided with the identification codes 13 and the suction nozzles 4 not provided with the identification codes 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 includes a computer system 1000. The computer system 1000 includes a processor 1001 such as a cpu (central Processing unit), a main memory 1002 including a nonvolatile memory such as a rom (read Only memory) and a volatile memory such as a 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 the computer program from the memory 1003, expands the computer program in the main memory 1002, and executes the above-described processing in accordance with the computer program. In addition, the computer program may be transmitted to the computer system 1000 via a network.
According to the above-described embodiment, the computer program can cause the computer system 1000 to execute: whether or not an identification code 13 is provided for each of a plurality of nozzles 4 included in a mounting head 5 for mounting an electronic component C on a board P is detected, and the nozzle 4 provided with the identification code 13 is used in preference to the nozzle 4 not provided with the identification code 13.
[ Effect ]
As described above, according to the embodiment, the priority command unit 24 is provided, and the priority command unit 24 outputs a priority command for using the nozzle 4 provided with the identification code 13 in preference to the nozzle 4 not provided with the identification code 13 based on the detection data of the detection device 8. In the electronic component mounting device 1, in the case where the nozzles 4 provided with the identification codes 13 and the nozzles 4 not provided with the identification codes 13 are mixedly present, if the nozzles 4 not provided with the identification codes 13 are used, it may be difficult to implement nozzle management or traceability management. According to the embodiment, in the case where the nozzles 4 provided with the identification codes 13 and the nozzles 4 not provided with the identification codes 13 are mixedly present, the nozzles 4 provided with the identification codes 13 are preferentially used, and therefore, nozzle management or traceability management can be performed in the field.
The nozzle management is to manage the number of times the nozzle 4 is used (the number of times suction is performed). The deterioration state of each of the plurality of nozzles 4 is managed by nozzle management. Traceability management is to manage the suction nozzles 4 used in the production of electronic devices. By traceability management, the suction nozzle 4 used in the production of the electronic device is determined. By mounting the electronic component C only by the nozzle 4 provided with the identification code 13, nozzle management or traceability management is smoothly performed.
The priority command unit 24 outputs a priority command based on input data generated by the input device 10. For example, there may be a case where nozzle management or traceability management is important, and a case where improvement in yield of electronic equipment is important. When nozzle management or traceability management is important, the operator input device 10 operates to output a priority command. Thus, since the electronic component C is mounted on the board P using only the nozzle 4 provided with the identification code 13, nozzle management or traceability management can be performed on site. In a case where improvement in productivity of the electronic device is important, the operator operates the input device 10 without outputting the priority command. Accordingly, the electronic component C is mounted on the substrate P using both the nozzle 4 provided with the identification code 13 and the nozzle 4 not provided with the identification code 13, and therefore, productivity of the electronic apparatus is improved.
The nozzles 4 provided with the identification codes 13 and the nozzles 4 not provided with the identification codes 13 are notified by the notification means 11. The notification device 11 notifies the time required for mounting the electronic component C on the substrate P using only the nozzle 4 provided with the identification code 13 and the time required for mounting the electronic component C on the substrate P using both the nozzle 4 provided with the identification code 13 and the nozzle 4 not provided with the identification code 13. Thus, the operator is provided with a criterion for judging whether to output the priority command. The operator can appropriately determine whether or not to output the priority command based on the notification data output from the notification device 11, and operate the input device 10.
[ other embodiments ]
In the above-described embodiment, when the priority command is output, the electronic component C is mounted by the 5 nozzles 4 provided with the identification codes 13, and when the priority command is not output, the electronic component C is mounted by the 5 nozzles 4 provided with the identification codes 13 and the 3 nozzles 4 not provided with the identification codes 13. The priority instructions may include a 1 st priority instruction using only the suction nozzles 4 provided with the identification codes 13, and a 2 nd priority instruction using a specific number of the suction nozzles 4 provided with the identification codes 13 and the suction nozzles 4 not provided with the identification codes 13. For example, when the 2 nd priority command is output, the electronic component C is mounted by the 5 nozzles 4 provided with the identification code 13 and the 1 st nozzle 4 not provided with the identification code 13.
In the above-described embodiment, the priority command section 24 outputs the priority command based on the input data generated in the input device 10. The priority command unit 24 may be configured to: a priority instruction for preferentially using only the suction nozzle 4 provided with the identification code 13 is output based not on the input data of the input device 10 but on the detection data of the detection device 8.
In the above-described 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.
