Detailed description of the invention
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail this utility model.
As shown in Figures 1 to 4, a kind of screening frock for hexagonal chip, including chip screen tray 1 and cover plate 2, described core
Sheet screen tray is provided with at groove 1-1, and the groove 1-1 of chip screen tray and is provided with multiple sieve aperture 1-2, the edge of described chip screen tray 1
It is provided with positioning screw hole 1-3, and cover plate 2 is provided with the location screw 2-1 matched with above-mentioned positioning screw hole 1-3, when cover plate 2 covers
Time on chip screen tray 1, the distance between the groove 1-1 of cover plate 2 and chip screen tray 1 is less than the height of hexagonal chip.
Preferably, as it is shown in figure 5, described screening frock also includes chip sucker 3, described chip sucker 3 is provided with multiple
Adsorption hole 3-1 and the through hole connected with adsorption hole 3-1, keep negative pressure in described through hole, to adsorb hexagonal chip at chip
On the adsorption hole 3-1 of sucker 3；The edge of described chip sucker 3 is provided with and positions the positioning screw hole 3-2 that screw 2-1 matches.
Alternatively, as it is shown in figure 5, one end of described chip sucker 3 is additionally provided with for collecting not by chip sucker suction
Disposable box 3-3 of the hexagonal chip lived.
Preferably, described cover plate 2 is made up of lucite material.
Being placed on PVC plastic film by the hexagonal silicon chip full wafer pulled and carry out sliver, sliver is put into the screen tray of design after completing
On cover plate, afterwards turn over 360 degree, take away PVC plastic film, make hexagonal chip to be screened be placed on cover plate 2.
A kind of screening technique for hexagonal chip utilizing above-mentioned screening frock to carry out, comprises the following steps:
Step S1, is positioned over hexagonal chip to be screened on cover plate 2, then is covered on cover plate 2 by chip screen tray 1 and make to determine
Screw 2-1 and positioning screw hole 1-3 position, position overlaps, and coordinating of screw 2-1 and positioning screw hole 1-3 makes chip screen tray 1 by location
Fix with cover plate 2 and be connected；
Step S2, overturns 180 ° by the cover plate 2 behind location with chip screen tray 1, makes the chip fragment being mingled with in hexagonal chip,
Especially the chip fragment of triangle, leaks down from the sieve aperture 1-2 of chip screen tray 1；If desired, also can oscillate chip screen tray
The chip fragment of triangle is screened out.
Further, described screening frock also include chip sucker 3, described chip sucker 3 be provided with multiple adsorption hole 3-1 and
The through hole connected with adsorption hole, keeps negative pressure in described through hole, so that hexagonal chip is adsorbed the adsorption hole 3-at chip sucker 3
On 1, described chip sucker 3 being additionally provided with vacuum adapter, vacuum adapter connects with above-mentioned through hole；The limit of described chip sucker 3
Edge is provided with and positions the positioning screw hole 3-2 that screw 2-1 matches；
After described step S2, also including step S3 of suction piece, described suction piece step S3 is as follows:
Step S3, overturns to cover plate 2 again by the hexagonal chip after screening, then passes through to determine with chip sucker 3 by cover plate 2
Position screw 3-2 is fixing with location screw 2-1 to be connected, and then cover plate 2 and chip sucker 3 is overturn 180 °, then by chip sucker 3
Vacuum adapter connect vaccum suction pipe, and be transferred to suitable tolerance, in making through hole, keep negative pressure, so that every hexagonal chip is equal
Absorption is on the adsorption hole 3-1 of corresponding chip sucker 3；If desired, the chip sucker 3 that also can oscillate make hexagonal chip according to
The hole count of adsorption hole 3-1 is filled up.
Further, one end of described chip sucker 3 is additionally provided with for collecting the chip do not lived by chip sucker suction
Disposable box 3-3；
After step S3, also include tilting chip sucker 3, make unnecessary hexagonal chip fall into the step of disposable box 3-3.
Finally being taken away by the cover plate 2 on chip sucker 3, chip sucker 3 overlaps with the tool locating of next station, closes true
Sky makes chip naturally fall in frock hole.
Chip screen tray 1 of the present utility model is used for screening various sizes of hexagonal chip, makes chip fragment from sieve aperture 1-2
Leaking down, the size of sieve aperture 1-2 can be according to the size adjusting of chip；This utility model by cover plate 2 and chip screen tray 1 with the use of,
Distance between the groove 1-1 of cover plate 2 and chip screen tray 1, less than the height of hexagonal chip, is to stop hexagonal chip in screening
During overturn, thus keep the direction of hexagonal chip；Screening technique of the present utility model can high efficiency by chip fragment from
Hexagonal chip sifts out, meets the requirement produced in enormous quantities, thus reach the purpose of cost efficiency.
