An embodiment will be described with reference to FIGS. FIG.
1 is an overall configuration diagram of an electronic component inspection device provided with a storage device of the present embodiment. In the figure, 1 is a storage device, 2
Denotes an electronic component inspection unit, and 3 denotes a feeder. The electronic component is taken out from the first storage device 1a that stores the magazine in which the electronic component is stored, sent to the inspection unit 2 by the feeding device 3a, and subjected to the inspection. The inspected electronic components are sorted according to the inspection result, transported by the second to fourth feeding devices 3b to 3d to the respective storage devices 1b to 1d, and stored.

The configuration of the storage device 1a on the side that sends out stored electronic components will be described with reference to FIGS. As shown in FIGS. 1 and 2, the frame 4 of the present apparatus 1 a has a box shape in which the upper and lower sides of a pair of side plates 5 and 6 are connected by a top plate 7 and a bottom plate 8, respectively. As shown in FIGS.
A rotary shaft 10 is provided between the side plates 5 and 6 via a bearing 9. Disks 11 and 12 are fixed to both ends of the rotating shaft 10 close to the inner surfaces of the side plates 5 and 6, respectively. A large number of rails 13 as cylindrical storage members are mounted between the pair of disks 11 and 12 to form a storage drum 14. As shown in FIG. 5 and FIG.
Is a member for accommodating a magazine 16 accommodating the electronic component 15, and a groove 1 for taking the accommodated magazine 16 out.
7. Although the rail of this embodiment has the shape shown in FIG. 5, the electronic component 15a to be stored and the magazine 16a
For example, a rail 18 having a shape as shown in FIG.
Can be replaced with As shown in FIG. 4, these rails 13 are arranged at predetermined intervals in parallel with the rotating shaft 10 so as to form a cylindrical outer peripheral surface along the outer periphery of the disks 11, 12. It is fixed between twelve.

As shown in FIGS. 1 to 3, a driving device 20 and a position fixing device 21 are provided on the outer surface of one side plate 6 of the frame 4 as a positioning mechanism for the storage drum 14. A motor 22 of the driving device 20 is linked to the rotating shaft 10 via a speed reducer 23, and can rotate the storage drum 14 by an arbitrary angle.

The position fixing device 21 has a cylinder 24 and a pin 25 interlocked with the cylinder 24. As shown in FIG.
The disk 12 has a ring-shaped receiving member 26 on each rail 1.
It is provided circumferentially corresponding to the position of No. 3. This disk 1
The side plate 6 between the pin 2 and the pin 25 is provided with a hole 6a, and the pin 25 protruding in the direction of the disk 12 is inserted into the receiving member 26 by the cylinder 24 so that the position of the storage drum 14 can be accurately determined. Is to be fixed. The receiving member 26 is made of a material that is slidable with respect to the pin 25, and the entrance side thereof is tapered so that the pin 25 can be inserted without resistance.

As shown in FIG. 2, openings 27 and 28 are provided in the side plates 5 and 6 above the storage drum 14, respectively. A bracket 29 is attached to one side plate 6 outside the opening 28. Further, three guide rods 30 are provided between the other side plate 5 and the bracket 29. A cylinder 31 is movably provided on the guide bar 30 as a means for taking out an electronic component. As shown in FIG. 1 and FIG.
Is installed. The operation unit 32 includes two guide rods 3
It has a base 35 guided to 3, 34 and an operation plate 36 connected thereto. A spring 37 for absorbing shock is interposed between the base 35 of the operation plate 36 and one of the guide bars 34 so that the operation plate 36 that moves together with the cylinder 31 can move with respect to the cylinder 31.

As shown in FIGS. 1, 2 and 7, the operation plate 36 is inserted into the groove 17 of the rail 13 set at the top of the storage drum 14. When the cylinder 31 is moved, the operation plate 36 moves in the rail 13, and the electronic component 15 is pushed out of the rail 13 while leaving the empty magazine 16 in the rail 13. In FIG. 1, a bracket 38 is provided near an opening 27 provided in the side plate 5 on the side from which the electronic component 15 is extruded, and a feeder or the like for transporting the extruded component to the next process is installed. I can do it.

The operation of the above configuration will be described. The magazine 16 in which the electronic components 15 are stored is stored in the rail 13. Then, in response to a command from an electronic component inspection unit or the like, the rail 13 in which the desired component is stored is positioned at the top of the storage drum 14, which is the take-out position. First, the storage drum 14 is rotated by a required angle by the motor 22 to perform almost accurate positioning, and then the cylinder 25 inserts the pin 25 into the receiving member 26. Thereby, the storage drum 14 is accurately positioned at a desired position.

Next, the cylinder 31 operates and the rail 13
The operation plate 36 is inserted from one of the open ends. Rail 13
The electronic component 15 inside is pushed by the operation plate 36 and is pushed out from the other open end of the rail 13. Extruded electronic components 15
Is transported to the inspection unit by a feeding device (not shown).

In the above-described embodiment, the storage device on the side that sends out the stored electronic components has been described. However, an empty magazine is stored in the rail and used to receive the inspected electronic components. Can also. In this case, the cylinder 31 which is a means for taking out an electronic component is not necessary, and instead, a configuration is provided in which a means for receiving the electronic component or a magazine containing the electronic component in the rail 13 is provided.

[0016]

The storage device of the present invention has a storage drum in which cylindrical storage members are circumferentially arranged, and can be positioned at any position. Therefore, according to the present invention, more electronic components can be stored with respect to the installation area of the device than a flat storage device. Also, since any storage member can be set at the work position, the work of taking out and receiving the electronic component can be performed quickly and smoothly.
