Abstract

A chip separation and alignment apparatus capable of accurately and readily accomplishing separation and alignment of chips with a simple construction. The apparatus includes a chip separation and alignment section and a chip separation section. The chip separation and alignment section includes a chip cassette formed into a flat rectangular box-like shape, in which are formed a chip storage chamber, a chip alignment hole provided with an upper end opening through which the chip alignment hole is communicated with a lower portion of the chip storage chamber and a lower end opening, and at least one air ejection port arranged near the upper end opening to intermittently eject air therethrough. The chip separation section is arranged at the lower end opening of the chip alignment hole to separate chips one by one and to successively supply the separated chips to a subsequent step.

Claims

1. A chip separation and alignment apparatus comprising:

(a) a chip separation and alignment section;

(b) said chip separation and alignment section comprising a chip cassette formed into a flat rectangular box-like shape;

(c) said chip cassette being formed therein with;

(i) a chip storage chamber;

(ii) a chip alignment hole provided with an upper end opening through which said chip alignment hole is communicated with a lower portion of said chip storage chamber and a lower end opening; and

(iii) at least one air ejection port arranged near said upper end opening to intermittently eject air therethrough; and

(c) a chip separation section arranged at said lower end opening of said chip alignment hole to separate chips one by one and successively supply said separated chips to a subsequent step,

(d) wherein said chip separation section includes;

(i) a see-saw rod formed at a distal end thereof with a shutter for operating said lower end opening of said chip alignment hole and pivotally mounted below said lower end opening and

(ii) a chip suction head arranged in front of said lower end opening so as to be reciprocated by a predetermined distance.

2. A chip separation and alignment apparatus as defined in claim 1, wherein said see-saw rod:

(a) is pivotally moved by means of a spring to close said lower end opening with said shutter and

(b) is pivotally moved by action of a solenoid against said spring to release said lower end opening from said shutter.

3. A chip separation and alignment apparatus as defined in claim 1, wherein said chip suction head:

(a) holds a foremost one of said chips alignedly stored in said chip alignment hole thereon by suction and

(b) transfers it by a predetermined distance when said lower end opening is released from said shutter.

4. A chip separation and alignment apparatus comprising:

(a) a chip separation and alignment section;

(b) said chip separation and alignment section comprising a chip cassette formed into a flat rectangular box-like shape;

(c) said chip cassette being formed therein with;

a chip storage chamber;

(ii) a chip alignment hole provided with an upper end opening through which said chip alignment hole is communicated with a lower portion of said chip storage chamber and a lower end opening; and

(iii) at least one air ejection port arranged near said upper end opening to intermittently eject air therethrough; and

(c) a chip separation section arranged at said lower end opening of said chip alignment hole to separate chips one by one and successively supply said separated chips to a subsequent step,

wherein;

(d) said chip separation section includes a rotor provided with a charger adapted to hold only one chip thereon and arranged to be rotatable within a predetermined angle; and

(e) said charger is positioned;

(i) to be communicated with said chip alignment hole and an air suction hole when said rotor is at a rotation starting position and

(ii) to be communicated with an air ejection hole and a discharge hole when said rotor is at a rotation terminating position.

5. A chip separation and alignment apparatus as defined in claim 4, wherein:

(a) said charger is provided at one end of said rotor;

(b) said rotor is provided at the other end of said rotor with a cam plate of which rotation is controlled within a predetermined angle by means of a stopper; and

(c) said cam plate is engaged with one end of a pivotal lever so that it may be reciprocatedly rotated within the predetermined angle due to pivotal movement of said pivotal lever to reciprocatedly rotate said rotor within the predetermined angle.
