(Effect of the first embodiment)
In the first embodiment, the following effects can be obtained.

In the first embodiment, as described above, the control unit 9 is the electronic component E supplied from each of the first identical component supply unit 20a and the second identical component supply unit 20b among the plurality of identical component supply units 20. Is mounted on the board B arranged at the same board work position W, and the first same component supply is based on the fact that the remaining number of the electronic components E of the first same component supply unit 20a is less than the threshold value. The supply of the electronic component E by the unit 20a is stopped, and the electronic component E supplied from the first identical component supply unit 20a is switched to the control supplied from the second identical component supply unit 20b. As a result, the electronic component E can be supplied from the second identical component supply unit 20b to the substrate B arranged at the same substrate work position W as when the electronic component E was supplied from the first identical component supply unit 20a. The electronic component E supplied from the same component supply unit 20a can be reliably supplied from the second identical component supply unit 20b. As a result, the mounting of the electronic component E can be performed on behalf of the board B without arranging the board B at different board work positions W. Further, when the remaining number of electronic components E in the first identical component supply section 20a becomes less than the threshold value, the reel on which the tape on which the electronic component E is arranged is wound is newly transferred to the first identical component supply section 20a. Since there is no need to supply, new reels can be prevented from being used. As a result, it is possible to more reliably suppress the increase in the number of used reels. Further, since it is not necessary to newly supply the reel around which the tape on which the electronic component E is arranged is wound to the first same component supply unit 20a, the reel replacement work by the operator can be reduced, so that the operator can reduce the reel replacement work. The work load can be reduced.

Further, in the first embodiment, as described above, the control unit 9 acquires the remaining number of the electronic components E of each of the plurality of identical component supply units 20, and at a predetermined timing, the first identical component supply unit It is configured to control whether or not the remaining number of the electronic components E acquired in 20a is less than the threshold value. As a result, it is confirmed whether or not the remaining number of acquired electronic components E is less than the threshold value at a predetermined timing after acquiring the remaining number of electronic components E of each of the plurality of identical component supply units 20. Therefore, it is possible to surely confirm whether or not the remaining number of the electronic components E of the first identical component supply unit 20a is less than the threshold value.

Further, in the first embodiment, as described above, the component mounting device 100 includes a storage unit that stores the association information 9a in which the arrangement location information of the plurality of identical component supply units 20 is associated with each other. When the remaining number of electronic components E in the first identical component supply unit 20a becomes less than the threshold value, the control unit 9 acquires the placement location information of the second identical component supply unit 20b based on the association information 9a. It is configured as follows. As a result, the placement location information of the second identical component supply unit 20b can be easily acquired by the association information 9a, so that the placement location information of the second identical component supply section 20b and the second identical component supply section 20b can be obtained. Compared to the case where the location of the second identical component supply unit 20b is not related and is brute-forced, the electronic component E supplied from the first identical component supply unit 20a is supplied as the second identical component. It is possible to efficiently switch to the control supplied from the unit 20b.

Further, in the first embodiment, as described above, each of the first head 5 and the second head 6 includes a plurality of rotary heads in which a plurality of nozzles N are arranged in a ring shape in a plan view. When the control unit 9 sequentially sucks the electronic component E from the first identical component supply unit 20a by the plurality of nozzles N of each of the plurality of rotary heads, the remaining number of the electronic component E of the first identical component supply unit 20a is reduced. Based on the fact that the value is less than the threshold value, the rotary head sucked from the first identical component supply unit 20a among the plurality of rotary heads and the second identical component supply unit 20b among the plurality of rotary heads are attracted. It is configured to switch to the control of supplying the electronic component E from the second identical component supply unit 20b shared by the rotary head, and continue the mounting of the electronic component E on the substrate B. As a result, before the remaining number of the electronic components E of the first identical component supply section 20a becomes less than the threshold value, the electronic components E are sequentially sucked from the first identical component supply section 20a by the plurality of nozzles N of the rotary head. Thereby, it is possible to suppress an increase in time for adsorbing the electronic component E on each of the plurality of nozzles N. Further, after the remaining number of the electronic parts E of the first same parts supply unit 20a becomes less than the threshold value and the supply of the electronic parts E from the first same parts supply unit 20a is stopped, the electronic parts E are arranged. Since it is not necessary to newly supply the reel around which the tape is wound to the first identical component supply unit 20a, it is possible to prevent the new reel from being used. As a result, it is possible to suppress an increase in the mounting time required for mounting the electronic component E on the substrate B, and it is possible to more reliably suppress an increase in the number of used reels.

Further, in the first embodiment, as described above, the plurality of identical component supply units 20 are preset so as to supply the electronic component E instead when the electronic component E is exhausted in the first identical component supply unit 20a. It has the fourth identical component supply unit 20d. The control unit 9 receives electrons from the fourth identical component supply unit 20d based on the fact that the electronic component E becomes less than the threshold value in the first identical component supply unit 20a until the production of the substrate B ends. It is configured to switch to the control supplied by the component E. The control unit 9 has a fourth identical component supply unit based on the fact that the remaining number of electronic components E in the first identical component supply unit 20a becomes less than the threshold value when the production of the substrate B ends. Instead of 20d, the electronic component E supplied from the first identical component supply unit 20a is switched to the control supplied from the second identical component supply unit 20b. As a result, parts can be supplied by the first identical component supply unit 20a or the fourth identical component supply unit 20d and the second identical component supply unit 20b until the end of the production of the substrate B, so that the second component can be supplied. It is possible to suppress a decrease in the production efficiency of the substrate B as compared with the case of the final stage in which the electronic component E is supplied only from the same component supply unit 20b. Further, by switching the control to supply the electronic component E supplied from the first identical component supply unit 20a from the second identical component supply unit 20b at the final stage of the production of the substrate B, the first operation is performed at the final stage of the production of the substrate B. The supply of the electronic component E from the same component supply unit 20a and the fourth identical component supply unit 20d can be stopped. As a result, as compared with the case where both the first identical component supply section 20a or the fourth identical component supply section 20d and the second identical component supply section 20b are used at the end of the production of the substrate B, the used reel Can be suppressed more reliably.

For example, the first component C1 is arranged in the first identical component supply unit 20a. The type of head that attracts the first component C1 of the first identical component supply unit 20a is, for example, the head 505 (described as H1 in FIGS. 14, 16 and 18). Further, the type of the nozzle N that adsorbs the first component C1 of the first identical component supply unit 20a is, for example, the first nozzle N1. As the same component supply unit information of the first location P1, for example, the first component C1 arranged at the second location P2 is set. As the same component supply unit information of the first location P1, for example, the first component C1 arranged at the third location P3 is set.

For example, the second identical parts supply unit 20b is arranged at the second location P2. For example, the first component C1 is arranged in the second identical component supply unit 20b. The type of head that attracts the first component C1 of the second identical component supply unit 20b is, for example, the head 505 (described as H1 in FIGS. 14, 16 and 18). Further, the type of the nozzle N that adsorbs the first component C1 of the second identical component supply unit 20b is, for example, the second nozzle N2. As the same component supply unit information of the second location P2, for example, the first component C1 arranged at the first location P1 is set. As the same component supply unit information of the second location P2, for example, the first component C1 arranged at the third location P3 is set.

For example, the third identical parts supply unit 20c is arranged at the third location P3. For example, the first component C1 is arranged in the third identical component supply unit 20c. The type of head that attracts the first component C1 of the third identical component supply unit 20c is, for example, the head 505 (described as H1 in FIGS. 14, 16 and 18). Further, the type of the nozzle N that adsorbs the first component C1 of the third identical component supply unit 20c is, for example, the third nozzle N3. As the same component supply unit information of the third location P3, for example, the first component C1 arranged at the first location P1 is set. As the same component supply unit information of the third location P3, for example, the first component C1 arranged at the second location P2 is set.

For example, the fourth identical parts supply unit 20d is arranged at the fourth location P4. For example, the first component C1 is arranged in the fourth identical component supply unit 20d. The type of head that attracts the first component C1 of the fourth identical component supply unit 20d is, for example, the first head. Further, the type of the nozzle N that adsorbs the first component C1 of the fourth identical component supply unit 20d is, for example, the first nozzle N1. For example, it is not set as the same component supply unit information of the fourth location P4.

As shown in FIGS. 14 and 15, the control unit 509 usually has the first identical component supply unit 20a of the first location P1, the second identical component supply unit 20b of the second location P2, and the third location P3. It is configured to control the supply of electronic components E from all of the third identical component supply units 20c.

Here, as shown in FIGS. 16 and 17, in the control unit 509, the electronic component E is the threshold value in the first identical component supply unit 20a of the first location P1 until the production of the substrate B is in the final stage. It is configured to switch to the control of supplying the electronic component E from the fourth identical component supply unit 20d of the fourth location P4 based on the fact that the value is less than the limit. Specifically, the control unit 509 is based on the fact that the remaining number of electronic components E in the first identical component supply unit 20a of the first location P1 becomes 0 until the production of the substrate B ends. , The electronic component E is replenished from the fourth identical component supply unit 20d of the fourth location P4 set in advance.

Further, as shown in FIGS. 18 and 19, when the production of the substrate B ends in the control unit 509, the remaining number of the electronic components E in the first same component supply unit 20a becomes less than the threshold value. Based on this, the electronic component E supplied from the first identical component supply unit 20a instead of the fourth identical component supply section 20d at the fourth location P4 is supplied from the second identical component supply section 20b at the second location P2. It is configured to switch to supply control. The other configurations of the fifth embodiment are the same as the configurations of the first embodiment.

(Effect of the fifth embodiment)
In the fifth embodiment, the following effects can be obtained.

In the fifth embodiment, similarly to the first embodiment, the control unit 509 is supplied from each of the first identical component supply unit 20a and the second identical component supply unit 20b among the plurality of identical component supply units 20. When the electronic component E is mounted on the board B arranged at the same board working position W, the number of remaining electronic components E in the first same component supply unit 20a is less than the threshold value. 1 It is configured to stop the supply of the electronic component E by the same component supply unit 20a and switch to the control of supplying the electronic component E supplied from the first identical component supply unit 20a from the second identical component supply unit 20b. ing. As a result, the mounting of the electronic component E can be performed on behalf of the board B without arranging the board B at different board work positions W.

Further, in the fifth embodiment, as described above, the head 507 includes an in-line head in which a plurality of nozzles N are arranged on a straight line. When the control unit 509 simultaneously causes the electronic component E to be sucked from each of the plurality of identical component supply units 20 by the plurality of nozzles N of the inline head, the remaining number of the electronic component E of the first identical component supply unit 20a is reduced. Based on the fact that the value is less than the threshold value, the nozzle N that has been sucked from the first identical component supply unit 20a among the plurality of nozzles N and the nozzle N that has been sucked from the second same component supply unit 20b among the plurality of nozzles N are sucked. It is configured to switch to the control of supplying the electronic component E from the second identical component supply unit 20b shared by the nozzle N, and continue the mounting of the electronic component E on the substrate B. As a result, before the remaining number of the electronic components E of the first identical component supply unit 20a becomes less than the threshold value, the electronic components E are simultaneously supplied from each of the plurality of identical component supply units 20 by the plurality of nozzles N of the inline head. By causing the suction operation, the electronic component E can be efficiently sucked to each of the plurality of nozzles N. Further, after the remaining number of the electronic parts E of the first same parts supply unit 20a is less than the threshold value and the supply of the electronic parts E from the first same parts supply unit 20a is stopped, the electronic parts E are arranged. Since it is not necessary to newly supply the reel around which the tape is wound to the first identical component supply unit 20a, it is possible to prevent the new reel from being used. As a result, the efficiency of mounting the electronic component E on the substrate B can be improved, and the increase in the number of used reels can be suppressed more reliably. The other effects of the fifth embodiment are the same as the effects of the first embodiment.
