[0009]

According to the first or fourth aspect of the present invention, with the above-described configuration, the supply means mounted on the component supply table does not house the entire component assembly but increases the weight of the component assembly. The reel-shaped winding portion occupying the portion is stored in a component storage table which is a table separated from the component supply table. In the part supply table, only the leading end of the part assembly is pulled out from the supply means. That is, on the parts supply table,
Since there is only a supply unit that is a unit for feeding the tip end of the component assembly at a predetermined pitch, the weight can be reduced substantially by the weight of the component assembly. Further, since the rigidity of the component supply table itself is not required as in the conventional case, the weight can be reduced, and the weight can be significantly reduced. Therefore, the weight of the component supply table can be significantly reduced as compared with the case where the conventional component supply table is divided into a plurality of parts, and no vibration occurs even when the component supply table moves at high speed. In addition, components can be supplied from a component assembly of more types than before using the component supply table. Further, according to the second aspect of the present invention, the component storage table in which the reel-shaped winding portions of the component assembly are stored in parallel with the component supply table that moves to the component supply position also moves. Since the reel-shaped winding part and the supply means from which the leading end of the reel-shaped part is drawn out face each other, the parts supply table drawn out in parallel does not interfere with each other, and the parts supply table is smoothly and surely provided. At a predetermined pitch. Therefore, even if the reel-shaped winding portion of the component assembly is not stored in the component supply table, the components can be reliably and continuously supplied, that is, the component supply that is reduced in weight and can be moved at high speed. The table makes it possible to reliably supply more types of parts than ever before. Further, the third invention or the fifth invention of the present application.
According to the present invention, since the component storage table storing the reel-shaped winding portion of the component assembly can be moved at a lower acceleration than the component supply table for supplying the component, the component storage supporting most of the weight of the component assembly can be moved. Vibration of the table can be suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

1 to 3, reference numeral 1 denotes a component supply table, 2 denotes a supply table driving unit, and 3 denotes a supply table control unit that controls the supply table driving unit 2. On the component supply table 1, a large number of supply means for sending out a set of electronic components in which minute components are held at equal intervals on a strip-shaped long material at constant intervals are mounted. 4 is a component storage table, 5 is a storage table driving unit, and 6 is a control unit that controls the storage table driving unit 5. Reference numeral 7 denotes a suction nozzle for sucking an electronic component. Reference numeral 8 denotes a reel cassette in which an electronic component assembly in which electronic components are held at equal intervals by a strip-shaped long material is stored in a reel shape.
Are mounted in parallel at regular intervals, and the leading end of the component assembly drawn from each reel cassette 8 is set in each supply means on the component supply table 1.

The operation of the component supply device and the suction nozzle 7 configured as described above will be described below. First, a supply unit is set on the component supply table 1. Further, a reel cassette 8 in which the electronic component assembly is wound in a reel shape and stored on the component storage table 4 corresponding to the position is installed. The component supply table 1 is driven at the same time as the component storage table 4 to start moving, and moves toward a suction point at which the suction nozzle 7 sucks an electronic component. When the movement of the component supply table 1 is completed, the component supply table 1 is in a stationary state until the suction nozzle 7 completes sucking the electronic component. On the other hand, the component storage table 4 moves so as to coincide with the component supply table 1 until the suction nozzle 7 completes the suction of the electronic component.

FIG. 4 shows a timing chart of each operation of the component storage table 4, the component supply table 1, and the suction nozzle 7. In FIG. 4, a graph 1 is a component storage table 4.
6 is a graph showing a relationship between a moving time and a moving speed of the occupant. Graph 2 is a graph showing the relationship between the moving time and the moving distance of the component supply table 1. Graph 3 is a graph showing the operation of the suction nozzle 7. The time indicated by T1 is the time when the suction nozzle 7 is stopped, and the time indicated by T2 is the time when the suction nozzle 7 is sucking the electronic component.

As apparent from FIG. 4, the control of the component supply table 1 and the component storage table 4 is based on the total time of the movement time of the component supply table 1 and the suction time during which the suction nozzle 7 sucks the electronic component from the supply device. Parts storage table 4
And the movement distance of the parts supply table 1 and the movement distance of the parts storage table 4 are controlled to coincide with each other. As a result, the moving speed of the component supply table 1 moves at a higher acceleration and a higher deceleration than the moving speed of the component storage table 4, and the component supply table 1 is in a stationary state during the time when the suction nozzle 7 sucks the electronic component. The component storage table 4 is in a moving state. Also, the parts supply table 1
The relative position of the electronic component assembly and the component storage table 4 changes during the movement, but the relative displacement is absorbed by the deformation of the long strip in the electronic component assembly.

[0015]

According to the present invention, the supply means mounted on the component supply table does not contain the entire component assembly, but includes a reel-shaped winding portion which occupies most of the weight of the component assembly. Are stored in a component storage table which is a table separated from the component supply table. In the part supply table, only the leading end of the part assembly is pulled out from the supply means. That is, since there is only a supply unit on the component supply table, which is a unit for feeding the tip end of the component assembly at a predetermined pitch, the weight can be reduced substantially by the weight of the component assembly. Further, since the rigidity of the component supply table itself is not required as in the conventional case, the weight can be reduced, and the weight can be significantly reduced. Therefore, the weight of the component supply table can be significantly reduced as compared with the case where the conventional component supply table is divided into a plurality of parts, and no vibration occurs even when the component supply table moves at high speed. In addition, components can be supplied from a component assembly of more types than before using the component supply table. Also, according to the component supply table that moves to the position for supplying components, the component storage table that stores the reel-shaped winding portions of the component assembly in parallel also moves,
The reel-shaped winding part of the component assembly is controlled so as to face the supply means from which the tip end is pulled out, so that the component assemblies pulled out in parallel do not interfere with each other, ensuring smooth and reliable operation. Can be sent at a predetermined pitch to the supply means in the component supply table. Therefore, even if the reel-shaped winding part of the component assembly is not stored in the component supply table, it is possible to reliably supply the component continuously.
In other words, a component supply table that is lightweight and can move at high speed can reliably supply more types of components than ever before. Further, since the component storage table storing the component assembly can be moved at a lower acceleration than the component supply table that supplies the components, vibration of the component storage table that supports most of the weight of the component assembly can be suppressed. .
