Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Field of the present invention is a cylindrical chip component having a magnetic material at its end;
For example, it relates to a transfer device such as a leadless diode.

In the manufacturing process of conventional chip components, for example, there is a process of stamping the outer circumferential surface of the chip component to indicate performance and polarity and then transporting it, and a process of checking the external appearance while transporting the chip component after stamping. .

Problems to be solved by the invention As a chip component transfer device used in such a process,
As shown in FIG. 6, a stainless steel belt 34 that is thinner than an extremely small diameter chip component is provided with a number of recesses 36 for accommodating chip components 35, and the heald 34 is driven and rotated. However, the heald 34 wore out in a short period of time and had to be replaced frequently, which was extremely disadvantageous in terms of cost and cost.

In addition, in the transfer process after the stamp is stamped, the stamp part is rubbed due to the rotation of the chip component 35, and the stamp may be erased.

The present invention has been devised in consideration of the above-mentioned circumstances, and aims to provide a suitable transfer device that does not cause the stamp to disappear.

In order to achieve the above object, a chip component transfer device according to the present invention has a magnet that attracts one of the cylindrical chip components having a magnetic cap electrode extending to the end thereof, which is attached to a moving body at a predetermined interval. It is characterized by the fact that it is provided in

Effects According to the above characteristic configuration, the end portion of the chip component can be magnetically attracted and the chip component can be transferred without the peripheral surface of the chip component coming into sliding contact with another object.

Embodiment Hereinafter, embodiments of the present invention will be explained based on the drawings. Fig. 1 shows an outline of a stamping processing equipment for unfinished chip parts, and includes a marking equipment 1 and a drying equipment for drying the chip parts after stamping with hot air. @2 and an appearance check equipment 3 for checking the appearance of chip parts after drying.

The chip component 4 to be stamped is, as shown in FIG.
Flange cap electrodes 6.6 made of a magnetic material are disposed on both sides of the glass tube 5, and the pellets 7 are sandwiched between the cap electrodes 6.6, which are sealed with glass. A minute gap is provided between the mark between the collar 8 of the electrode 6.6 and the end surface of the glass tube.

As shown in FIG.
This is an example of a moving object. A transfer device 11 for transferring magnetically attracted chip components 4 is constructed by stacking a plurality of stages at predetermined intervals on the outer peripheral surface side of a turntable 10 configured to be freely driven and rotatable around a vertical axis. 1] from the first supply section 12 of the chip components 4 to the drying facility (JN
A marking device 14 for stamping the outer peripheral surface of the magnetically attracted chip component 4 is disposed in the middle of a rotational transfer path across the second supply section 13 of the chip component 4 to the second supply section 13. A chute 15 that diagonally crosses the chip component transfer path is provided near the chute 15, and as the turntable 10 rotates, a mark is applied to the outer peripheral surface of the chip component 4, and the stamp is The rear chip component 4 comes into contact with the chute 15, and the chip component 4 at the core part
is forcibly scraped off against the magnetic force and fed into the second supply section 13 as it is.

The chip component attracting surface of the magnet 9 is set to about 1.0 to 1.5 times the diameter of the cap electrode 6, so that a single chip component 4 can be attached to the magnet 9 on the attracting surface. It is designed to be absorbed in an upright position.

The appearance check facility @3 is constructed as shown in FIGS. 4 and 5. That is, an endless belt 17, which is another example of a moving body, is provided with approximately circular boss portions 16 at predetermined intervals, and is rotatable around a horizontal axis and has substantially circular boss portions 16 at predetermined intervals.
At the same time, it is wound around a rotating body 18°]9 shaped to mesh with the
A holder 21 equipped with a magnet 20 that attracts the chip component 4 after drying is attached to each of the boss portions 16 via a bearing 22 so as to be freely rotatable about the horizontal axis, and one rotating body 18 is The magnet 20 is placed near the chip component take-out section 23 of the drying equipment 2, and the diameter of the chip component attraction surface of the magnet 20 is set to about 1.0 to 1.5 times the diameter of the cap 6.
Single chip components 4 are sequentially attracted to the magnet 20 from the chip component take-out section 23 and then linearly transferred.

Then, at a predetermined position along the transfer path of the chip component 4, an appearance checking device 24 such as an eye camera for visually detecting the quality of the stamping in the previous process is arranged.
Behind the checking device, there is a removal mechanism (a chip component striking mechanism connected to a solenoid 25 and its operating section) that eliminates defective chip components 4 from the path based on the detection information of appearance defects from the appearance checking device 24. Consists of a dropping tool 26)2
7 is arranged.

On the other hand, a roller 28 is connected to the end of the holder 21, and a magnet that rotates the magnet 20 by rotating the roller 28 as the belt 17 moves is placed near the location of the appearance checking device 24. A rotating member 29 is provided so that the chip component 4 attracted to the magnet 20 is rotated about its central axis in the appearance checking section by the appearance checking device 24.

Appearance check device 2 under rotation of this chip component 4
4, and when a defective chip component 4 is detected, the solenoid 25 is energized, and the chip component 4 is transferred to the defective product collection chute 30.
The chip parts 4 are shot down towards the target and collected in the box 31, and only the good parts are transferred as they are, and the good chip parts 4 come into contact with the chute 32 diagonally crossing the transfer path and are collected in the box 33. It has become so.

Effects of the Invention As described above, the chip component transfer device according to the present invention effectively utilizes the magnetic material at the end of the 1000-knob component to magnetically attract and transfer a single chip component. Therefore, the chip parts can be transported while floating in space, and there is no wear and tear caused by the sliding contact of the peripheral surface of the chip parts with other objects during transport, so the service life of the device is extremely long, and in particular, When such a transfer device is used for transfer in the stamping process,
This is preferable because it can prevent the stamp from disappearing.
