(C) Operation of Bulk Component Supply Device In the bulk component supply device 32, an electronic circuit component 410 is thrown into the container 100 of the component supply unit 82 by an operator, and the inserted electronic circuit component 410 is a component. By the operation of the supply unit 82 and the component delivery device 86, the component is supplied while being placed on the component receiving member 392 of the component carrier 388. Specifically, in the component supply unit 82, as shown in FIG. 10, when the electronic circuit component 410 is put in, the bottom deep portion 112 of the container 100 is positioned below the bottom shallow portion 110, and the container 100 extends in the vertical direction. State (hereinafter referred to as “vertical state”). And an operator throws in the electronic circuit component 410 from the opening of the container 100 in a vertical state. Thereby, the inserted electronic circuit component 410 is accommodated in the bottom deep portion 112 of the container 100, and the bottom deep portion 112 functions as a component accommodating portion.

Then, the container 100 swings so as to move the bottom shallow portion 110 downward, and the bottom shallow portion 110 is positioned below the bottom deep portion 112 from the vertical state as shown in FIG. The vessel 100 is inclined (hereinafter referred to as “inclined state”). At this time, the electronic circuit component 410 housed in the bottom deep portion 112 moves to the bottom shallow portion 110 via the connecting portion 114.

Next, the container 100 is swung so as to move the bottom deep portion 112 downward, and enters the vertical state from the inclined state as shown in FIG. At this time, the electronic circuit component 410 that has been moved to the bottom shallow portion 110 due to the swing to the inclined state is returned to the bottom deep portion 112 via the connecting portion 114. However, the electronic circuit component 410 that has moved to the shallow bottom portion 110 is caught by the protrusion 120, and one electronic circuit component 410 is locked to each of the plurality of protrusions 120.

Specifically, the dimension in the width direction of the protrusion 120 is smaller than twice the dimension in the width direction of the electronic circuit component 410, and the dimension in the height direction of the protrusion 120 is the height direction of the electronic circuit component 410. It is about the same size as Further, the separation distance of the plurality of protrusions 120 is larger than the dimension in the width direction of the electronic circuit component 410 and smaller than twice the dimension. For this reason, one electronic circuit component 410 is locked to each of the plurality of protrusions 120. That is, one electronic circuit component 410 is locked to one protrusion 120 without overlapping a plurality of electronic circuit components 410 in the vertical direction and adjacent in the left-right direction.

Then, the container 100 swings so as to move the bottom shallow portion 110 downward, and from the vertical state, the bottom shallow portion 110 and the bottom deep portion 112 have the same height as shown in FIG. The container 100 is in a horizontal state (hereinafter referred to as “horizontal state”). At this time, in the container 100, one electronic circuit component 410 is locked to each of the plurality of protrusions 120, and the upper surface of the locked electronic circuit component 410 is generally horizontal. As a result, the electronic circuit component 410 locked to the protrusion 120 can be supplied.

When the electronic circuit component 410 can be supplied in the container 100, the camera 290 of the imaging device 84 moves upward of the container 100 by the operation of the camera moving device 292 and images the electronic circuit component 410. . Then, information such as the position of the electronic circuit component 410 and the posture of the electronic circuit component 410 is acquired by the electronic circuit component 410 locked to the protrusion 120 based on the imaging data.

Then, the component holding head 302 is moved by the operation of the component holding head moving device 300 above the electronic circuit component 410 locked to the protrusion 120 based on the acquired position information of the electronic circuit component 410. The electronic circuit component 410 is sucked and held by the suction nozzle 332. When the electronic circuit component 410 is sucked and held by the suction nozzle 332, the suction nozzle 332 is located at the non-turning position.

Next, after the electronic circuit component 410 is held by the suction nozzle 332, the component holding head 302 is moved above the component carrier 388. At this time, the component carrier 388 moves to the component receiving position by the operation of the component carrier moving device 390. Further, when the component holding head 302 moves above the component carrier 388, the suction nozzle 332 is pivoted to the pivot position. Note that when the electronic circuit component 410 is a lead component, the suction nozzle 332 rotates the nozzle so that the lead 414 of the electronic circuit component 410 held by the suction nozzle 332 at the turning position faces downward in the vertical direction. It is rotated by the operation of the device 335.

When the component holding head 302 moves above the component carrier 388, the electronic circuit component 410 with the lead 414 facing downward in the vertical direction is inserted into the component receiving recess 416 of the component receiving member 392. Thus, when the electronic circuit component 410 is a lead component, the electronic circuit component 410 is placed on the component receiving member 392 with the leads 414 facing downward in the vertical direction as shown in FIG. The

When the electronic circuit component 410 is placed on the component receiving member 392, the component carrier 388 is moved to the component supply position by the operation of the component carrier moving device 390. Since the component carrier 388 moved to the component supply position is located in the movement range of the work heads 60 and 62, the electronic component 410 is supplied at this position in the loose component supply device 32. As described above, in the bulk component supply device 32, for example, when the electronic circuit component 410 is a lead component, the lead 414 faces downward and the top surface facing the bottom surface to which the lead 414 is connected faces upward. The electronic circuit component 410 is supplied. For this reason, the suction nozzle 66 of the work heads 60 and 62 can appropriately hold the electronic circuit component 410.

Further, in the bulk component supply device 32, in the container 100 of the component supply unit 82, the electronic circuit component 410 is engaged with each of the plurality of protrusions 120, and the electronic component is applied to the suction nozzle 332. A circuit component 410 is supplied. Thereby, compared with the conventional component supply unit, waste of work can be eliminated and work efficiency can be increased. Specifically, as shown in FIG. 14, the conventional component supply unit 500 includes a component supplier 502 and a component scattering device 504.

The component feeder 502 has a generally rectangular parallelepiped box shape, and an inclined plate 506 and a conveyor device 508 are generally arranged in a V shape inside the component feeder 502. Then, parts are put between the inclined plate 506 and the conveyor device 508 arranged in a V shape. At this time, the conveyor device 508 rotates counterclockwise in FIG. 14, so that the components are conveyed toward the upper end of the conveyor device 508. The components conveyed to the upper end of the conveyor device 508 fall from the upper end of the conveyor device 508 and are discharged from the opening 510 of the component feeder 502.

Also, the component scattering device 504 is disposed below the opening 510 of the component feeder 502 through which components are discharged. The component scattering device 504 includes a stage 512 and a stage moving device 514. The stage 512 has a generally longitudinal plate shape. The stage 512 is stored below the component feeder 502 below the opening 510 of the component feeder 502, and is exposed from below the component feeder 502. It is possible to slide between. Then, the stage 512 is controllably moved between the retracted state and the exposed state by the operation of the stage moving device 514.

For this reason, in the parts scattering apparatus 504, the stage 512 is in the retracted state before the parts are discharged from the opening 510 of the parts supplier 502, and at the timing when the parts are discharged from the opening 510 of the parts supplier 502. Move from the retracted state to the exposed state. As a result, the components discharged from the opening 510 of the component supplier 502 are scattered over the entire surface of the stage 512, and the scattered components are supplied to the suction nozzle 332. That is, the parts scattered on the stage 512 are held by the suction nozzle 332.

However, when components discharged from the opening 510 of the component supplier 502 are scattered on the stage 512, a plurality of components may overlap in the vertical direction. In addition, a plurality of parts may be adjacent in the left-right direction. In such a case, since the components cannot be appropriately held by the suction nozzle 332, the overlapped components and the adjacent components are not held by the suction nozzle 332 and are left on the stage 512. As described above, when parts are left on the stage 512, work is wasted and work efficiency is lowered.

On the other hand, in the component supply unit 82, one component is locked to each of the plurality of protrusions 120 of the container 100. That is, one component is locked to one protrusion 120 without overlapping a plurality of components in the vertical direction and adjacent in the left-right direction. For this reason, it is possible to hold all of the components locked to the protrusion 120 by the suction nozzle 332. Thereby, according to the component supply unit 82, compared with the conventional component supply unit, it is possible to reduce the waste of work and increase the work efficiency.

Further, in the conventional component feeder 502, since the conveyor device 508 rotates, a clearance is provided between the conveyor device 508 and the inclined plate 506. For this reason, a small part may fall from the clearance between the inclined plate 506 and the conveyor device 508, and the small part may not be handled as a part to be supplied. On the other hand, in the component supply unit 82, since there is no clearance inside the container 100, the component does not fall. Thereby, in the component supply unit 82, even a small component can be handled as a component to be supplied.

Furthermore, the structure of the component supply unit 82 is very simple compared to the conventional component supply unit 500. For this reason, according to the component supply unit 82, it is possible to achieve weight reduction, size reduction, cost reduction, and the like. By reducing the size, a large number of component supply units 82 can be arranged in the bulk component supply device 32, and the types of supply components can be increased. Specifically, in one component supply unit 82, the same type of component is usually supplied. For this reason, it is possible to supply many types of components by disposing a large number of component supply units 82. Here, in the bulk component supply device 32, ten component supply units 82 are disposed. On the other hand, in the conventional component supply unit 500, since it is necessary to arrange the component feeder 502 and the component scattering device 504 and to secure the slide range of the stage of the component scattering device 504, there are only a few component supply units 500. It cannot be installed. Therefore, by adopting the component supply unit 82, it is possible to supply many types of components as compared with the case where the conventional component supply unit 500 is employed.

Further, in the component supply unit 82, when the components locked to each of all the protrusions 120 in the horizontal container 100 are held by the suction nozzle 332, the container 100 again performs the above-described procedure. Accordingly, the component is locked to the protrusion 120. Then, the components locked to the protrusion 120 are supplied to the suction nozzle 332. Thus, when the parts accommodated in the container 100 are supplied, the number of parts accommodated in the container 100 decreases. At this time, as the number of parts decreases, the parts may not be locked to the protrusion 120 when the container 100 swings. That is, when the container 100 is swung from the vertical state shown in FIG. 10 to the inclined state shown in FIG. The number of parts that move to 110 is reduced, and it becomes difficult for the parts to be locked to the protrusion 120.

Therefore, in the component supply unit 82, when the container 100 is swung from the vertical state shown in FIG. 10 to the inclined state shown in FIG. 11, the individual control device 452 uses the detection signal of the contact sensor 162 based on the detection signal. Then, it is determined whether or not the component has contacted the inner wall surface of the shallow bottom portion 110. At this time, if it is determined that the part is in contact with the inner wall surface of the shallow bottom portion 110, the component moves from the bottom deep portion 112 of the container 100 to the bottom shallow portion 110, and further, the bottom shallow portion 110. It has moved to the inner wall surface on the opposite side to the bottom deep part 112 of. In other words, as the container 100 swings, the component moves through the protrusion 120 provided on the shallow bottom portion 110. In such a case, there is a high possibility that the component is locked to the protrusion 120. On the other hand, when it is determined that the component is not in contact with the inner wall surface of the shallow bottom portion 110, the component has not moved through the protrusion 120 provided in the shallow shallow portion 110. In such a case, the possibility that the component is locked to the protrusion 120 is low.

For this reason, when it is determined that the part is not in contact with the inner wall surface of the shallow bottom portion 110, the swing angle of the container 100 is changed so that the inclination angle of the container 100 is increased. More specifically, when the inclination angle of the container 100 with the bottom shallow portion 110 turned downward is, for example, 15 degrees, it is determined that the component is not in contact with the inner wall surface of the bottom shallow portion 110. There is. In such a case, the inclination angle of the container 100 with the shallow bottom portion 110 in the downward direction is newly specified as 30 degrees, and the container 100 is swung to the specified angle. That is, the container 100 is further swung after the container 100 is swung from the vertical state to a state where the tilt angle is 15 degrees, and the tilt angle of the container 100 is set to 30 degrees. At this time, since the shallow bottom portion 110 moves further downward than the bottom deep portion 112, the component moves until it passes through the protruding portion 120. Thereby, it becomes possible to latch a component to the projection part 120, and it becomes possible to supply a component suitably.

Also, the supply of parts from the container 100 may reduce and eliminate the number of parts housed in the container 100. In such a case, it is necessary to supply the container 100 with parts. For this reason, in the component supply unit 82, the presence / absence of a component accommodated in the container 100 is determined based on the detection signal of the passage sensor 160. Specifically, when the container 100 swings, the individual control device 452 determines whether or not a component has passed through the connecting portion 114 based on a detection signal from the passage sensor 160. That is, when it is swung from the vertical state shown in FIG. 10 to the inclined state shown in FIG. 11 and when it is swung from the inclined state shown in FIG. 11 to the vertical state shown in FIG. It is determined whether or not a part has passed between 110 and the bottom deep portion 112.

At this time, if it is determined that the part has passed between the bottom shallow part 110 and the bottom deep part 112, the part is naturally left inside the container 100. On the other hand, when it is determined that no part passes between the bottom shallow part 110 and the bottom deep part 112, there is a high possibility that no part remains in the container 100. For this reason, when the container 100 is swung, if it is determined that no part passes between the bottom shallow part 110 and the bottom deep part 112, it is determined that there are no parts stored in the container 100. The Then, an image indicating that the parts accommodated in the container 100 are lost is displayed on the display device 456. Thus, in the component supply unit 82, the presence / absence of the component accommodated in the container 100 is determined based on the detection signal of the passage sensor 160, and when there is no accommodated component, the fact is notified to the operator. Is done. Thereby, the operator recognizes that the parts accommodated in the container 100 are lost, and the parts are replenished inside the container 100.

Also, in the component supply unit 82, the dimensions of the protrusions 120 are determined according to the dimensions of the components to be supplied so that the components can be properly locked to the protrusions 120 in the container 100. For this reason, according to the kind of components of supply object, the multiple types of container 100 from which the dimension of the projection part 120 differs is prepared. When the type of the component to be supplied is changed, the container 100 is removed from the support unit 102, and the container 100 corresponding to the new component to be supplied is attached to the support unit 102. As a result, many types of components can be supplied.

Further, as illustrated in FIG. 9, the individual control device 452 includes a first swing part 520, a second swing part 522, a third swing part 524, a specifying part 526, and a detection part 528. The first swing part 520 is a functional part for swinging the container 100 from the vertical state shown in FIG. 10 to the inclined state shown in FIG. The second swinging part 522 is a functional part for swinging the container 100 from the inclined state shown in FIG. 11 to the vertical state shown in FIG. The third swing part 524 is a functional part for swinging the container 100 from the vertical state shown in FIG. 12 to the horizontal state shown in FIG. The specifying unit 526 specifies a new swing angle of the container 100 when the component does not contact the inner wall surface of the bottom shallow portion 110 of the container 100 when the container 100 swings, and the new swing is performed. It is a functional part for swinging the container 100 to an angle. The detection unit 528 is a functional unit for detecting whether or not a component is accommodated in the container 100 based on a detection signal of the passage sensor 160 when the container 100 is swung.

In addition, this invention is not limited to the said Example, It is possible to implement in the various aspect which gave various change and improvement based on the knowledge of those skilled in the art. Specifically, for example, in the above-described embodiment, the protruding portion 120 having a convex shape is employed as the locking portion for locking the component, but a concave shape may be employed. Moreover, when the latching | locking part of components is made into the dimension substantially the same as the dimension of components, the position of the component latched by the latching | locking part is decided. In such a case, it is not necessary to specify the locking position of the component based on the imaging data, and a preset position can be set as the component supply position.

Moreover, in the said Example, the presence or absence of the components accommodated in the container 100 is based on whether a component moves between the bottom shallow part 110 and the bottom deep part 112 at the time of the swing of the container 100. Although determined, the presence / absence of a component accommodated in the container 100 may be determined by another method. For example, when a sensor is provided inside the bottom deep portion 112 and the container 100 is swung in a vertical state, if no component is detected by the sensor, it is determined that no part is stored in the container 100. May be. Further, for example, when the container 100 is swung in an inclined state, the bottom shallow portion 110 is imaged by the camera 290, and the presence / absence of a component accommodated in the container 100 is determined based on the imaging data. May be.

Further, in the above embodiment, based on information on the component when the container 100 swings from the vertical state to the inclined state, that is, based on information on whether or not the component is moving to the inner wall surface of the shallow bottom portion 110, Although a new swing angle of the container 100 is specified, the swing angle of the container 100 may be specified by other methods. For example, the swing angle of the container 100 may be specified based on information on various parts such as part dimensions, part types, and the number of parts.

Further, in the above embodiment, the parts are supplied after the container 100 is swung in the order of the vertical state, the inclined state, the vertical state, and the horizontal state. Also good. For example, the vertical state and the inclined state may be one cycle, and after the container 100 is swung for two or more cycles, the container 100 may be swung to the horizontal state to supply the parts. That is, the parts may be supplied after the container 100 is swung in the order of the vertical state, the inclined state, the vertical state, the inclined state, and the horizontal state.
