The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2, the structure of grinding clamp of the present invention is, comprise load dish 16, load dish 16 upper surfaces are fixedlyed connected with fixed weight bar 2, the below of load dish 16 is positioning seats 6, positioning seat 6 is hollow opening round recesseds down, load dish 16 and positioning seat 6 have two corresponding through holes, two through holes of positioning seat 6 all are provided with locating slide sleeve 14, pass respectively in each through hole and regulate support bar 1 and fixed support bar 3, regulating support bar 1 and fixed support bar 3 can be up and down along locating slide sleeve 14, fixed support bar 3 is provided with screw thread with the end circumferential surface that adjusting support bar 1 is connected with load dish 16, regulate support bar 1 and be connected with load dish 16 with nut C17 by adjustment disk 15, two groups of nut A4 were connected with load dish 16 with packing ring 5 about fixed support bar 3 passed through.
Because grinding clamp weares and teares easily with the part that the polisher lapper master contacts, so the downward groove at positioning seat 6 grinds packing ring 9 along being provided with, so that wearing and tearing are more in time changed, the following groove that grinds the screw 12 of packing ring 9 by interior hexagonal cylinder head dummy and positioning seat 6 is along being connected, regulate support bar 1 and fixed support bar 3 and load dish 16 and all pass through positioning seat 6 realization vertical and horizontal motions, the location of both direction just can be realized vertically and be horizontally rotated to positioning seat 6 like this; Be provided with an angular deflection dish 8 in the cavity of positioning seat 6, angular deflection dish 8 has axle center hole, be respectively arranged with the hinge mount 7 and the high-order lug 19 of low level along the diameter two ends of angular deflection dish 8, hinge mount 7 is connected with fixed support bar 3 by straight pin 13, lug 19 is a kind of lugs with ellipsoid shape eccentric pin hole, lug 19 is connected with adjusting support bar 1 by another straight pin 13, the lower surface of angular deflection dish 8 is equipped with bonding die dish 10, the axle center of bonding die dish 10 is provided with threaded post 18 upwards, and threaded post 18 is passed the axle center hole of angular deflection dish 8 and fixed by nut B11.
The course of work of grinding clamp of the present invention is,
At first, bonding die dish 10 is taken off from angular deflection dish 8, wafer to be processed is sticked on bonding die dish 10 centers, then, the bonding die dish 10 that is stained with wafer to be processed is passed the axle center hole of angular deflection dish 8 through the threaded post 18 of self, fastening with nut B11 and angular deflection dish 8;
Second step, the lower end of regulating the lower end of support bar 1 and fixed support bar 3 is passed the locating slide sleeve 14 of positioning seat 6 upper surface through holes respectively, fix (wherein with angular deflection dish 8, it is fixing to regulate the lug 19 usefulness straight pins 13 of support bar 1 on angular deflection dish 8, fixed support bar 3 is fixing with angular deflection dish 8 by straight pin 13 through hinge mount 7, guarantee to regulate support bar 1,3 slips of fixed support bar freely, accurate positioning;
The 3rd step, the upper end of fixed support bar 3 is fastening with nut A4, the packing ring 5 of load dish 16 upper and lower surfaces, regulating support bar 1 links to each other through adjustment disk 15, nut C17 and load dish 16 successively, adjust the lifting of regulating support bar 1 with adjustment disk 15 and nut C17, change the deflection angle of angular deflection dish 8, also changed simultaneously the angle of wafer to be processed and horizontal plane, after regulating, with adjustment disk 15, load dish 16 usefulness nut C17 locking;
The 4th goes on foot, and the grinding clamp of the present invention that is stained with wafer to be processed is placed on carries out attrition process on the polisher lapper master, and the peak of the processing sheet on the bonding die dish 10 is-horizontal level (on the master of polisher lapper) same with grinding packing ring lower surface all the time.In the process of lapping, angular deflection dish 8, bonding die dish 10 and paste thereon wafer to be processed and under the drive of the compressing of added counterweight on the fixed weight bar 2 and load dish 16 and positioning seat 6, swing simultaneously and rotate, making wafer be subjected to the drift angle grinds, simultaneously along with the increase of grinding the degree of depth, polisher lapper control fixed weight bar 2 and progressively vertical subsidence of load dish 16, the drift angle milling area is increased gradually, finally cover whole wafer to be processed and make the orientation of wafer abradant surface that the change of expection take place.Take off this wafer to be processed then, the good crystal face of mill and the bonding die dish of wafer to be processed is bonding, according to preceding step grinding another side, finally make the entire wafer change or revised original crystal orientation.
Grinding clamp of the present invention makes the bonding die dish by positioning seat and pastes thereon processed wafer and abrasive disk and keeps the angle that needs, and this angle can be by the lifting adjusting arbitrarily within the specific limits of regulating support bar.In the process of lapping, angular deflection dish, bonding die dish and paste thereon wafer and under the drive of the compressing of load dish and positioning seat, swing simultaneously and rotate, making wafer be subjected to the drift angle grinds, simultaneously along with the increase control load dish vertical subsidence of grinding the degree of depth, the drift angle milling area is increased gradually, final cover entire wafer and make the orientation of wafer abradant surface that the change of expection take place, be typically designed to 0 °～10 °.Take off wafer then, will newly be orientated the bonding grinding another side of crystal face and bonding die dish, finally make the entire wafer change or revised original crystal orientation.
Grinding clamp of the present invention is simple in structure, make easy for installation, easily control, cost is low, is the corollary apparatus of polisher lapper, can be used for the drift angle degree processing of artificial lens wafer.
