DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an object supply apparatus, and more particularly to an object supply apparatus which simplifies the mechanism of the apparatus and shortens the operation time.

[0002]

2. Description of the Related Art An object, for example, an electronic component such as an electrolytic capacitor is accommodated in a film tray for packaging which is an object accommodating portion. FIG. 4 is a schematic perspective view of a general film tray 1 for packaging. In FIG. 4, the packaging film tray 1 has a plurality of first holes 1a formed therein.
The electronic component is inserted and held in a. 1st hole 1a
Consists of a second hole 1b and a detent 1c. 2nd hole 1
b is a portion where the pin of the electronic component is inserted, and the second hole 1
A detent 1c is formed at the end of b. The electronic component is taken out of the packaging film tray 1 after the electronic component is rotated and the pin is brought into contact with the detent 1c. Because
This is because the electronic component must always be positioned in a fixed direction with respect to the circumferential direction. That is, it is necessary to take out the electronic component from any electronic component contained in the packaging film tray 1 so that the position of the pin of the electronic component in the circumferential direction is always constant.

[0003] Therefore, the above-mentioned packaging film tray 1
FIG. 5 shows a system diagram of a conventional object supply device 2 used when an electronic component W is taken out from the device and attached to a substrate or the like. In FIG. 5, the object supply device 2 includes an object transporting unit 3, an object moving unit 4, and the like. The electronic components W are stored in the packaging film tray 1, and the object transporting means 3 holds the electronic components W stored in the packaging film tray 1 by chucking. Then, the object transporting means 3 removes the electronic component W from the packaging film tray 1. Thereafter, the object transporting means 3 moves to place the chucked electronic component W on the positioning tray 5. Next, the object moving means 4 is moved to the positioning tray 5.
And chucks and holds the electronic component W stored in the positioning tray 5. Then, the object moving means 4 moves to the upper part of the substrate 6, the electronic component W is positioned at a predetermined position on the substrate 6, and the electronic component W is inserted into the substrate 6.

[0004]

According to the method described above,
The electronic components must be positioned from the packaging film tray 1 to the substrate 6 for the following reasons. Due to the structure of the packaging film tray, play is always generated between the film tray and the electrolytic capacitor, and if the electrolytic capacitor is grasped in this state, there is a gap in the circumferential direction due to play. For this reason, it is necessary to take out the packaging film tray 1 once, transfer it to the positioning tray 5, and then mount it on the substrate 6 or the like. However, according to the above-described method, there is a problem that a work time loss is generated as compared with a case where the packaging film tray 1 is directly mounted on the substrate 6 and the production efficiency is deteriorated. Further, in order to accommodate the electronic component W from the packaging film tray 1 to the substrate 6,
Two mechanisms, the object transporting means 3 and the object moving means 4, are required, and there is a problem that the mechanism is complicated as a whole apparatus.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide an object supply apparatus having a simple mechanism and capable of shortening the operation time.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to provide a method for holding an object from an object storage section in which a cylindrical object is removably accommodated, and providing the object to a target supply section. In an object supply device for mounting an object on the other hand, an object holding unit for holding the object stored in the object housing unit, and a rotation connected to the object holding unit and rotating the object holding unit Means, connected to the rotating means, moving means for moving the rotating means, provided between the rotating means and the object holding portion, the rotating power given to the object holding portion from the rotating means This is achieved by an object supply device having a clutch portion for clutching.

In the present invention, the object held by the object holding unit is held by the object holding unit, and the object is positioned by rotating the object holding unit by the rotating means. At this time, when a predetermined force is applied to the object, the clutch unit stops transmitting the rotational power to the object. Thus, the target object can be directly conveyed from the target object storage unit to the target object supply unit without once positioning the target object at another place, so that time loss can be eliminated and the mechanism of the apparatus can be simplified.

Although various technically preferable limits are given, the scope of the present invention is not limited to these modes unless otherwise specified in the following description.

FIG. 1 is a perspective view showing a preferred embodiment of the object supply apparatus of the present invention. The object supply apparatus 10 will be described in detail with reference to FIG. The object supply device 10 in FIG. 1 includes a moving unit 20, a rotating unit 30, an object holding unit 40, a clutch unit 50, and the like. First, FIG.
The moving means 20 will be described in detail with reference to FIG. The moving means 20 includes an X rail 21, a Y rail 22, and a cylinder 2.
It consists of 3 mag. The X rail 21 is connected to the Y rail 22, and the Y rail 22 moves along the X rail 21 in the arrow X direction. The Y rail 22 is connected to the cylinder 2
3, the cylinder 23 moves in the arrow Y direction along the Y rail 22. Further, the cylinder 23 has a shaft 35
When the cylinder 23 operates, the shaft 35 moves in the arrow Z direction.

Next, FIG. 2 is an enlarged perspective view showing a peripheral portion of the rotating means 30, and the rotating means 30 will be described in detail with reference to FIG. The rotating means 30 has a motor 31, pulleys 32 and 33, a pulley belt 34, and the like. The motor 31 is connected to a pulley 32, and the pulley 32 is connected to a pulley 33 via a pulley belt 34. The pulley 33 is connected to the shaft 35. When the motor 31 rotates, the pulley 32 also rotates in synchronization, and the pulley 33 rotates via the pulley belt 34. And
When the pulley 33 rotates, the shaft 35 also rotates in synchronization with the rotation.

Next, the object holder 40 will be described in detail with reference to FIG. The object holding section 40 is the chuck claw 4
1 and 41, and the chuck claws 41 and 41 are connected to an air cylinder or the like (not shown). When the air cylinder operates, the chuck claws 41, 41 move in the direction of arrow Y1, and chuck and hold the electronic component W. The object holding unit 40 is connected to the clutch unit 50, and the clutch unit 50 is connected to the shaft 35.

FIG. 3 is a sectional view of the clutch unit 50. The clutch unit 50 will be described in detail with reference to FIG. The clutch unit 50 includes a housing 51 and a plate 5
2, the bearings 53, 53, the clutch plate 54, the spring 55 and the like. A plate 52 is fixed to an upper portion of the housing 51, and an object holding portion 40 is connected to a lower portion. A bearing 53 is provided on the housing 51 and the plate 52,
53 are provided, and the shaft 35 is inserted into the bearings 53, 53. Thereby, the housing 51,

When the shaft 35 rotates, the clutch plate 54 fixed to the shaft 35 rotates. Since the clutch plate 54 is in contact with the plate 53 by the spring 55, the plate 52 rotates by the frictional force with the clutch plate 54. Then, the housing 51 fixed to the plate 52 rotates, and the object holder 40 connected to the housing 51 is rotated.
Rotates. On the other hand, when a constant force is applied to the housing 51 in the anti-rotation direction, the rotation of the housing 51 and the plate 52 stops. Then, the plate 52 and the clutch plate 54
As a result, the torque transmitted from the shaft 35 is cut off. Thus, the object holding unit 4 is driven by the motor 31.

Rotate a certain amount in the direction.

At this time, the electronic component W hits the detent 1b provided on the packaging film tray 1 in FIG. 4, and the rotation of the electronic component W stops. At this time, the clutch unit 50 is engaged and the transmission of the rotational power to the object holding unit 50 is cut off. This can prevent the electronic component W from being damaged. Thereafter, the cylinder 23 operates to move the object holder 40 in the direction of the arrow Z1 and is positioned on the substrate 6 by the X rail 21 and the Y rail 22. After that, the object holder 40 is moved in the direction of arrow Z2 by the cylinder 23, and the electronic component W is arranged on the substrate 6.

According to the above embodiment, since the electronic component W can be positioned on the substrate while being held on the packaging film tray 1, the time can be reduced. Also,
The mechanism is simple, and the device itself can be easily manufactured at low cost. Further, when the deforming inserter itself has a rotation mechanism, it can be further simplified. And the positioning device of the electronic component W becomes unnecessary.

By the way, the present invention is not limited to the above embodiment. In the above embodiment, the target object W is an electrolytic capacitor as an example, but the present invention can be applied to electronic components and other members having a cylindrical shape. Although the clutch unit 50 uses a so-called friction clutch, an electromagnetic clutch may of course be used.
