Benefits of technology

[0026] It is preferable that the measuring terminals are contacted simultaneously with the electronic parts held in the cavities in the lines. For example, when the transport medium has four concentric lines of cavities, by taking a characteristic measurement with measuring terminals contacted simultaneously with four elec

Problems solved by technology

For some recently improved electronic parts such as chip-type capacitors, however, the capacitance has been increased, and the measuring time (time for measuring insulation resistance) tends to be longer than prior capacitors.
When characteristic discrimination is performed for these electronic parts, which need a l

Example

[0062]FIG. 10 shows a transport device according to a second embodiment of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and repetitive descriptions thereof are omitted.

[0063] This embodiment adopts a turntable 3 serving as a transport medium which rotates about a horizontal axis and has two concentric lines of cavities 5. The same number of parts feeders 10 and separating mechanisms 40 are provided as the number of lines of the cavities 5. When electronic parts C are introduced in each parts feeder 10 at random, they are aligned in line and are successively conveyed along a path 15a of a linear feeder 15. The electronic parts C conveyed to the distal end of the linear feeder 15 are separated into the leading electronic part and subsequent electronic parts by a separating mechanism 40. The separating mechanism 40 may adopt, for example, a separating method similar to that in FIG. 7. The leading electronic par...

Example

[0067]FIG. 11 shows a third embodiment as a modification of the second embodiment shown in FIG. 10.

[0068] In this embodiment, guide plates 43 and 44, made of a transparent acrylic board or the like, are placed on both sides of a turntable 3. This can stabilize the attitudes of electronic parts C which are conveyed while being held inside cavities 5 of the turntable 3.

[0069] The front-side guide plate 43 has a cutout portion 43a corresponding to a receiving section and a removal section.

[0070] While the front- and back-side guide plates 43 and 44 are shown having no holes, in reality, they have holes or openings through which measuring terminals or the like are passed.

Example

[0071]FIG. 12 to 17 show a transport device according to a fourth embodiment of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and repetitive descriptions thereof are omitted.

[0072] In this embodiment, a turntable 3 having four concentric lines of cavities 5, in a manner similar to that in the first embodiment, is used as a transport medium. A feeding disk 50 disclosed in Japanese Unexamined Patent Application Publication No. 11-208871 is used as a supply means.

[0073] In the transport device of this embodiment, electronic parts C are separated by the feeding disk 50 which is placed in an inclined state. The same number of electronic parts as the number of lines of cavities 5 of the turntable 3, which is rotating about the horizontal axis, are simultaneously supplied into the cavities 5 at a receiving section 42 (see FIG. 12).

[0074] The feeding disk 50 is placed on an inclined base 52 so as to slide at a pred...

Abstract

An electronic part transport device includes a transport medium having a plurality of lines of cavities. The lines are concentric with respect to the rotation axis. A driving device rotationally drives the transport medium. A supply device separately supplies a plurality of randomly introduced electronic parts one by one. A delivery device feeds the electronic parts separately supplied by the supply device into the cavities of the transport medium. A removal device takes the electronic parts out of the cavities of the transport medium.

Description

[0001] This application is a continuation of application Ser. No. 09 / 899,222 filed Jul. 6, 2001, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a transport device for separately transporting, one by one, small electronic parts, such as chip-type capacitors and to an inspection apparatus using the transport device. [0004] 2. Description of the Related Art [0005] In recent years, there is an increase in the number of requests for characteristic-discriminating apparatuses for electronic parts. The characteristic-discriminating apparatus is needed to inspect various characteristics by a single apparatus. In order to meet such a request, Japanese Unexamined Patent Application Publication No. 2-195272 proposes a characteristic measuring apparatus which includes a movable table with a plurality of retaining holes for passing and holding electronic parts so that both ends ...
