Abstract
The utility model discloses a novel lower grinding disc structure. The novel lower grinding disc structure comprises a lower grinding disc, a plurality of S-shaped blades are uniformly distributed on the upper surface of the lower grinding disc along the circumferential direction, a plurality of deflector holes are formed in the edge of the lower grinding disc along the circumference, the upper mouth of the deflector hole is provided with a mouth sealing piece, an annular baffle block is mounted at the outer side of the lower grinding disc, and a sealing component is mounted at the joint between the annular baffle block and the lower grinding disc. The S-shaped blades of the lower grinding disc can fasten the grinding speed and greatly improve the grinding efficiency. Grinding sand liquid and small wafers are blocked by the annular baffle block when splashing, so that the surrounding environment pollution is avoided. The cleaning is finished through using a brush to sweep the grinding sand liquid and small wafers to the deflector holes, so that the novel lower grinding disc structure is convenient and easy to clean.
Description
Technical field
The utility model relates to a kind of new grinding lower disc, belongs to wafer grinding manufacture field.
Background technology
When crystal block is dispatched from the factory, its surface is all more coarse, need to grind by grinder.For the grinder of wafer grinding processing, in process, grinding upper disc and grinding lower wall are in the time of grinding wafers, have grinding sand liquid and wafer in small, broken bits splashes, cause the pollution of working environment, because lapping liquid belongs to chemicals, wafer debris is too broken little again, is difficult to clear up the pollution that causes surrounding environment.And along with developing rapidly of wafer industry, at present more and more higher to the technical requirement of wafer grinding.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of new grinding lower disc for above drawback, in improving grinding precision, the phenomenon of having avoided in process of lapping grinding sand liquid and wafer in small, broken bits to splash, improves working effect, increases work efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of new grinding lower disc, comprises grinding lower wall, and wherein, described grinding lower wall upper surface has been uniformly distributed circumferentially many " S " type blades, and between described " S " type blade, angulation θ is 30 degree; Under described grinding, plate edge is provided with multiple pod apertures along circumference, and described pod apertures is inclined to set in grinding lower wall, and described pod apertures is 45 degree with grinding lower wall lower surface angulation δ, and in described pod apertures, aperture is provided with sealed piece; Described grinding lower wall outside is provided with collar stop, described collar stop is provided with containment member with grinding lower wall junction, described containment member is made up of two " N " type sealing rings and " Z " type sealing ring, is multi-sealing structure, and between three sealing rings, gap forms labyrinth seal.
A kind of new grinding lower disc, wherein, the quantity of described " S " type blade is 12.
A kind of new grinding lower disc, wherein, described two " N " type sealing rings are positioned at the upper and lower two ends of " Z " type sealing ring.
Method of work: when use, grind lower wall and be the grinding that turns clockwise, stopped by collar stop around when grinding sand liquid and wafer in small, broken bits splash, drop on and grind on lower wall.After grinding finishes, ground wafer is taken out, the sealed piece in pod apertures is taken off, under pod apertures, place dustbin, use brush that grinding sand liquid and wafer in small, broken bits are swept to pod apertures.
Beneficial effect;
1, grind " S " type blade structure of lower wall and can accelerate milling time, greatly improve grinding efficiency.
2, when splashing, grinding sand liquid and wafer in small, broken bits stopped by collar stop around, avoid surrounding environmental pollution.
3, when cleaning, use brush that grinding sand liquid and wafer in small, broken bits are swept to pod apertures, convenient and simple.

Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is pod apertures schematic diagram of the present utility model.
Fig. 4 is seal member schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
As shown in the figure, a kind of new grinding lower disc, comprises and grinds lower wall 1, wherein, described grinding lower wall 1 upper surface has been uniformly distributed circumferentially many " S " type blades 2, and 2 angulation θ of described " S " type blade are 30 degree; Described grinding lower wall 1 edge is provided with multiple pod apertures 3 along circumference, and described pod apertures 3 is inclined to set in grinding lower wall, and described pod apertures 3 is 45 degree with grinding lower wall 1 lower surface angulation δ, and in described pod apertures 1, aperture is provided with sealed piece 4; Described grinding lower wall 1 outside is provided with collar stop 5, described collar stop 5 is provided with containment member 6 with grinding lower wall 1 junction, described containment member 6 is made up of two " N " type sealing rings 61 and " Z " type sealing ring 62, be multi-sealing structure, between three sealing rings, gap forms labyrinth seal.The quantity of described " S " type blade 2 is 12.Described two " N " type sealing rings 61 are positioned at " Z " type sealing ring, and Shang Xia 62 two ends.Described pod apertures 3 quantity are 8.
Method of work: when use, grind lower wall 1 and be the grinding that turns clockwise, stopped by collar stop 5 around when grinding sand liquid and wafer in small, broken bits splash, drop on and grind on lower wall 1.After grinding finishes, ground wafer is taken out, the sealed piece in pod apertures 34 is taken off, place dustbin 3 times in pod apertures, use brush that grinding sand liquid and wafer in small, broken bits are swept to pod apertures 3.
Beneficial effect; Grind " S " type blade structure of lower wall and can accelerate milling time, greatly improve grinding efficiency.When grinding sand liquid and wafer in small, broken bits splash, stopped by the collar stop of Zhou Wei, avoid surrounding environmental pollution.When cleaning, use brush that grinding sand liquid and wafer in small, broken bits are swept to pod apertures, convenient and simple.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
