Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process in which chips (various small electronic components, for example, chip registers) are separately loaded into recesses of a rotor one by one and conveyed to a next process, and are provided close to the rotor. Provided is a chip front-back aligning / conveying device in which chips are aligned (aligned) in a front (or back) direction by rotation of a disc wheel.

[0002]

2. Description of the Related Art Conventionally, one chip conveyed in a row by a feeder or the like is inserted into each recess of a rotor in which recesses for chip loading are formed at regular intervals in a circumferential portion of a disk that rotates at high speed. An automatic separating and conveying means for chips is widely used in which chips are separated, transferred, loaded, transferred, and transferred one by one to the chip tape or other chip holding means.

[0003] Some chips may be simply separated and transported to a single chip without causing any problem with the front and back sides, and one chip may be arranged in a front (or back) direction such as a chip register. There are some which must be separated and conveyed to individual pieces and transferred to a chip tape or the like in that state.

Conventionally, the above-mentioned front-to-back alignment is mainly performed in a ball feeder in front of a single-row conveying feeder (straight feeder) facing a concave portion of a rotor, and the ball feeder randomizes a large number of chips on a ball. And the chips are aligned and conveyed in a line by vibration, and the front-side (or front) -facing chips are prepared to return to the ball again by discrimination of the front / back discrimination sensor provided around them. Only the objects are sent to the single-row transport feeder, and then separated and loaded one by one into each recess of the rotor.

However, since the above-mentioned chip front-back aligning means is integrally formed as a part of the ball feeder, there is a problem that the ball feeder is extremely expensive as a special custom product. In addition, the discrimination is made in the middle of the process of aligning the chips in a row, so that the front and back of the chips are split in half, and almost half of the aligned chips are returned to the ball. , Speed) is reduced to about ２, which hinders speeding up of automatic separation and transfer of chips.
