Abstract
The utility model discloses a multi-wire cutting machine capable of preventing wire jump of a wire net, which comprises a cutting device and at least one input device, wherein the cutting device comprises a mortar nozzle, four wire guide wheels and a wire net wound on the wire guide wheels; the input device comprises a workbench, a workpiece frame, a workpiece plate and a glass plate which are sequentially connected from top to bottom; and a cushion strip is arranged between the workpiece frame and the workpiece plate. By adopting the structure, the multi-wire cutting machine disclosed by the utility model can avoid saw marks and keep the cleanness of the wire net so as to greatly improve the cutting quality.
Description
Technical field
The utility model relates to the cutting field of silico briquette, specifically can prevent the multi-line cutting machine of gauze wire jumper.
Background technology
The multi-wire saw technology is current more advanced silicon chip process technology, is adopted by most silicon chip manufacturer in world wide.Its principle is the cutting gauze that is wrapped in a level of formation on two or more guide rollers (distance between steel wire is determined by the guide roller slot pitch) that a superfine steel wire is parallel to each other, during cutting, guide roller drives gauze and does high-speed motion, the continual grinding milk (being generally the mixed liquor of PEG and SiC) that contains abrasive material that sprays to gauze of blast nozzle, work stage is moved towards gauze with the direction perpendicular to gauze with the speed of technological requirement simultaneously, gauze is brought abrasive material into the workpiece to be processed zone workpiece is ground to pin, the hard brittle materials such as silico briquette are cut into to thousands of thin slices.
In cutting process, enter cutter very important, original technology adopts at bonding two gib blocks of the resin perpendicular to gauze in silico briquette bottom, and gauze first cuts into the resin gib block, then cuts into silico briquette, easily produce the gauze fluctuation, and while entering cutter, the steel wire unbalance stress easily produces into the cutter stria, the resin gib block after cutting easily separates with silico briquette, enters gauze, produce wire jumper, impact cutting quality.
The utility model content
The utility model provides the multi-line cutting machine that can prevent the gauze wire jumper, solved multi-line cutting machine in the past in the silicon chip cutting process, easily produce the gauze fluctuation, and while entering cutter, the steel wire unbalance stress easily produces into the cutter stria, resin gib block after cutting easily separates with silico briquette, enter gauze, produce wire jumper, the problem of impact cutting quality.
The utility model is the technical solution problem, adopt following technological means to realize: the multi-line cutting machine that can prevent the gauze wire jumper, comprise cutter sweep and at least one input unit, cutter sweep comprises mortar nozzle, four guide rollers and is wrapped in the gauze on guide roller, input unit comprises workbench, work rest, work plate, the glass plate connected successively from top to bottom, is provided with filler strip between described work rest and work plate.When cutting, silico briquette is fixed on the glass plate below, by increasing filler strip, making the lower surface of silico briquette horizontal by certain angle, is namely that silico briquette lower surface and gauze are at an angle, like this, contacting by the face contact between gauze and silico briquette become a little and contacted, and need to gauze, not guide cutting at silico briquette bottom increase resin gib block, thus can not produce the resin chip, can on silico briquette, not produce stria yet.
Further, as preferred version, described input unit has two, and one of them input unit is positioned at the top of gauze, and another input unit is positioned at the annular that gauze surrounds.
Further, as preferred version, described input unit has three, and one of them input unit is positioned at the top of gauze, and two other input unit is positioned at the annular that gauze surrounds.
Further, as preferred version, described input unit has four, and wherein two input units are positioned at the top of gauze, and two other input unit is positioned at the annular that gauze surrounds.
Further, as preferred version, described filler strip is positioned at left end or the right-hand member of work rest.
Further, as preferred version, described filler strip is made by stainless steel.
Further, as preferred version, the thickness of described filler strip is 1mm or 2mm.
The utility model compared to existing technology, have following beneficial effect: the utility model is by arranging filler strip between work rest and work plate, make lower surface and the gauze of silico briquette have certain angle, thereby make contacting by the face contact between gauze and silico briquette become a little contact, be difficult for the generation stria; Simultaneously, do not need in the silico briquette bottom, the resin gib block to be set again, and then can not produce resin gib block fragment, guaranteed the clean of gauze, thereby greatly improved Si wafer quality and yield rate.
