Description
Technical field
The present invention relates to a kind of multi-wire saw technology, particularly relate to a kind of multi-wire saw equipment and tension adjustment mechanism thereof.
Background technology
Line cutting technology is current more advanced evolution process technology in the world, its principle is by the golden steel wire of high-speed motion, workpiece to be processed (for example: silicon rod, sapphire or other semiconductor hard brittle materials) to be rubbed, the side's of cutting out ingot, thus reach cutting object.In to the cutting process of workpiece, gold steel wire is by the guiding of guide roller, on main line roller, form a bracing cable net, and workpiece to be processed is realized the feeding of workpiece by the rise and fall of workbench, under the effect of compression pump, be assemblied in the cutting position that cooling water automatic spraying device on equipment is sprayed to cooling water golden steel wire and workpiece, move back and forth and produce cutting by golden steel wire, so that the hard brittle materials such as semiconductor are once cut into polylith simultaneously.Line cutting technology has compared with traditional knife saw sheet, grinding wheel and inner circle cutting that efficiency is high, production capacity is high, precision advantages of higher.
Such as crystalline silicon bar cutting-off machine of existing multi-wire saw equipment etc. at least includes conventionally: frame, be arranged in described frame for carrying the workbench of crystal silicon rod, for the reel of wrapping wire, multiple reels and liftable cutting roller etc., in to the cutting process of crystal silicon rod, steel wire is by the guiding of tens reels, on between multiple cutting rollers, form a pull spring net, and crystal silicon rod to be cut is while being fixed on described workbench, cutting roller is lowered, and under the effect of compression pump, be assemblied in the cutting position that cooling water automatic spraying device on equipment is sprayed to cooling water golden steel wire and crystal silicon rod, move back and forth workpiece is produced to cutting by golden steel wire, so that crystal silicon rod is once cut into several sections simultaneously.
In above-mentioned cutting operation, the effect of golden steel wire is very important, even if but best golden steel wire, its ductility and abrasion resistance are also limited, that is to say that golden steel wire can be tapered in reciprocating motion, until be finally pulled off.Present multi-wire saw equipment (lathe) all can design golden steel wire tension force compensation mechanism, the ductility going and back running for making up golden steel wire.Fig. 1 is shown as golden steel wire tension force compensation mechanism schematic diagram in the linear cutting equipment of prior art, as shown in Figure 1, described golden steel wire tension force compensation mechanism comprises: be arranged at the drag board 11 in frame 10, be arranged on the cutting wheel 12 on drag board 11, guide roller 13, regulating wheel 14, gold steel wire 15 is wound in described cutting wheel 12, guide roller 13, and between regulating wheel 14, on described drag board 11, be also provided with air spring 16 for drawing regulating wheel 14 and for the tension force of sensing gold steel wire 15 such as, to drive the displacement transducer 17 of this Pneumatic extension part 16 (cylinder or air spring etc.).In cutting process, in the time that displacement transducer 17 senses tension force that the golden steel wire 15 that is wound on described regulating wheel 14 produces and changes, can order about described Pneumatic extension part 16 and pull described regulating wheel 14 in horizontal motion, and then the effect that reaches adjusting is to supplement the variation of this tension force.
But owing to adopting Pneumatic extension part as the driving element that absorbs tension force in this tension force compensation mechanism, and pneumatic element itself has the performance of elastic telescopic, in actual cutting process because the tension force of golden steel wire is constantly to change, such as in cutting process because the result of compensation tension force is while causing the tension force of golden steel wire to become large, this Pneumatic extension sword can discharge golden steel wire and cause golden steel wire lax, and then is unfavorable for cutting operation, moreover, the cutting wheel of the same side in the cutting equipment of technology is all arranged on same cutting roller now, and in cutting because golden steel wire has the different degrees of wear often to cause the changing of inequality in circumference of each cutting wheel to cutting wheel, and the result producing is that to be back and forth wound in steel wire tension on each cutting wheel different, and then cause the displacement transducer between described cutting wheel and guide roller can not accurately sense actual tension variation, , described Pneumatic extension sword can not obtain tension signal accurately and in time the tension force producing be absorbed, so be still unfavorable for cutting operation.
