Description

Chip automatic directional collating unit

Technical field

The utility model relates to a kind of chip automatic directional collating unit, is used for GPP chip processing procedure process and arranges both forward and reverse directions to cutting the sheet chip that looses.

Background technology

In the prior art, the GPP chip all adopts the sheet packaged form that looses, and is about to the small size chip that finished chip is laser-cut into designing requirement jointly, takes off from blue film through chip pick-up equipment, forms single little chip.After drawing into single-chip, need single-chip be tested one by one because of technology or experiment for indivedual batches, at this moment need the artificial tweezers that use that the chip unification is arranged in the zone of regulation by the negative or positive electrode direction.

But the arrangement operation of carrying out with staff owing to be the operation that relies on operator's skill level, because of the operator is different, can makes and arrange the needed time and ordered state is different, so it is low and can not obtain the problem of stable alignment form to exist capacity rating.Because of using tweezers pincer attack strength uncontrollable, be easy to cause strength to cross ambassador's chip rupture and lost efficacy in this process.

In order to address the above problem, Chinese patent number " 02154332.1 " discloses a kind of chip component collating unit, and open day is 2003.06.04, has the plate that is provided with the chip component arrangement plane; The housing that is configured on this plate and the fill area of chip component is set, supply with the component feeding portion of chip component to said plate; The chip component that the said plate of subtend is supplied with is given the swinging gear that horizontally rotates that horizontally rotates swing, makes the chip component collating unit can obtain the automation of the arrangement operation of chip component.

But because the PN junction of GPP chip has the corrosion concave surface; And above-mentioned patented technology chip component when arranging is to do to horizontally rotate swing; Make the GPP chip can not unify to be arranged in the zone of regulation by the negative or positive electrode direction; Thereby this patented technology and be not suitable for and arrange the GPP chip, can only adopt the mode of manual arrangement to carry out in the prior art equally.

Summary of the invention

The purpose of the utility model is to overcome the problems referred to above that GPP arrangements of chips both forward and reverse directions exists in the prior art; A kind of chip automatic directional collating unit is provided; The utility model is arranged the GPP chip as requested automatically by P face or N face; Guarantee chip quality, the chip broken invalid of avoiding the manual operation reason to cause.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:

A kind of chip automatic directional collating unit; It is characterized in that: involving vibrations dish and delivery track; Be provided with chip rest area and vibrating the track in the said vibrating disk, said vibrating the track one end is communicated with the chip rest area, and the other end is communicated with delivery track; Said vibrating the track is provided with the branch selections track in aggregates with vibrating the track, and the thickness of said minute selections track is less than the thickness of vibrating the track.

The thickness of said vibrating the track is 0.3-0.5mm.

The thickness of said minute selections track is 0.15-0.2mm.

Said delivery track is connected with vibrator.

Said vibrating the track shape in the shape of a spiral is distributed in the vibrating disk.

The selections track was positioned at the vibrating the track middle part in said minute.

Adopt the advantage of the utility model to be:

One, the utility model involving vibrations dish and delivery track are provided with chip rest area and vibrating the track in the said vibrating disk, said vibrating the track one end is communicated with the chip rest area; The other end is communicated with delivery track; Said vibrating the track is provided with branch selections track, and the thickness of said minute selections track adopts this structure that the GPP chip is arranged by P face or N face as requested automatically less than the thickness of vibrating the track; Guarantee chip quality; The chip broken invalid of avoiding the manual operation reason to cause, and the branch selections track that is provided with can be that the die grading of contact surface returns the chip rest area with the N face chip on the vibrating the track, makes separating effect more reliable.

Two, in the utility model; The thickness of said vibrating the track is 0.3-0.5mm; Further; The thickness of said minute selections track is 0.15-0.2mm, adopts this structure to guarantee that further with the N face chip on the vibrating the track be the reliability that the die grading of contact surface returns the chip rest area, improves the accuracy of arranging.

Three, in the utility model, said delivery track is connected with vibrator, makes through the consistent conveying on request of arrangements of chips after the vibration arrangement, and can adjust the chip of not arranging on request.

Four, this reality and novel in, said vibrating the track is shape in the shape of a spiral, the accuracy rate that makes the GPP chip automatically arrange by P face or N face as requested is higher.

Five, this reality and novel in, said minute selections track is positioned at the vibrating the track middle part, arranges through vibrating the track earlier, through dividing the sorting of selections track, improves accuracy again.
