Abstract
The utility model discloses a special tool for cutting a silicon block, which comprises a workbench for fixing the silicon block, a bonding plate fixedly connected with the workbench and glass arranged between the bonding plate and the silicon block, wherein the thickness of one side of the glass along the width direction is less than the thickness of the other side; and the oblique glass is fixed between the silicon block and the bonding plate; the silicon block also inclines toward one side, and oblique cutting of the silicon block can be realized. When in steel wire cutting, the cutting starts from the relatively thick side of the glass; although a wire arch is generated in the cutting process, the thickness of the other side of the glass can be determined according to the bending of the wire arch; and on the premise of guaranteeing the wire arch of the steel wire, the glass still can not be cut through along the thickness direction when the steel wire leaves the glass, and the steel wire can not touch the bonding plate so as to guarantee the using safety of the bonding plate. Thus, the consumable glass is cut open while the non-consumable bonding plate is not influenced, thereby protecting the structure of the bonding plate and guaranteeing the service life of the bonding plate.
Description
Technical field
The utility model relates to silicon chip production and processing technical field, particularly relates to a kind of specific purpose tool that cuts silico briquette.
Background technology
Silicon chip is to be processed by linear cutting equipment by silico briquette.
Please refer to Fig. 1 and Fig. 2, the working state schematic representation when Fig. 1 cuts for silico briquette, direction shown in the arrow is the direction of motion when cutting of silico briquette among the figure; Fig. 2 is the structural representation of a kind of specific purpose tool of typical case's cutting silico briquette in the prior art.
As shown in Figure 1, silico briquette 11 moves downward under the effect of workbench 13, cuts through steel wire 12 and by steel wire 12.Steadily go into cutter for what can realize silico briquette when cutting, generally can be at silico briquette cut surface adhering resin gib block 16, because the hardness ratio silico briquette of resin gib block 16 is low, so can realize the smooth transition of steel wire cutting.
Specific purpose tool shown in Figure 2, comprise the steel wire 12 that cuts silico briquette 11, parallel with two and all be fixedly connected with shown in the workbench 13(figure of silico briquette 11 be the jig of workbench 13), on workbench 13, be mounted with metal adhesive sheet 14, between metal adhesive sheet 14 and silico briquette 11, be bonded with ground glass 15.Steel wire 12 is used for silico briquette 11 by line cutting technology processing specific thicknesses silicon chip; Metal adhesive sheet 14 is used for the workpiece that installs and fixes with the platen jig, is the long-term non-consumptive material that uses; Ground glass 15 is bonded in the silicon chip cutting process in the middle of metal adhesive sheet 14 and the silico briquette 11, and its hardness is similar with silico briquette 11, plays the over effect of cutting, prevent to be damaged to metal adhesive sheet 14 after silico briquette 11 from cutting, ground glass 15 is disposable product, is consumptive material, and is discarded after cutting is finished.
Because the cutting mode of silicon chip is the line cutting, so online switching to can produce the line bow last the time, and this line bow is easy to cut glass 15 and injures adhesive sheet 14.For avoiding adhesive sheet 14 by cut wound, can change lathe hardware, change the original structure of adhesive sheet 14, this process has reduced the service life of adhesive sheet 14 easily.
Therefore, guarantee the service life of adhesive sheet in cutting to be the present technical issues that need to address of those skilled in the art.
The utility model content
The purpose of this utility model provides a kind of specific purpose tool that cuts silico briquette, can guarantee adhesive sheet in cutting process not by cut wound, do not influence its service life.
For realizing above-mentioned utility model purpose, the utility model provides a kind of specific purpose tool that cuts silico briquette, comprise the fixedly workbench of silico briquette, the adhesive sheet that is connected with described stationary table, and be located at glass between described adhesive sheet and the described silico briquette, described glass along a side thickness of its width less than opposite side thickness.
Preferably, described glass is right-angled trapezium along the cross section of its thickness direction.
Preferably, described glass is ground glass.
Preferably, the thickness difference of described glass one side and opposite side is 1.5-3mm.
Preferably, the thickness difference of described glass one side and opposite side is 1.7-2.3mm.
Specific purpose tool provided by the utility model, be used to adopt the inclination mode to cut silico briquette, this specific purpose tool comprises the fixedly workbench of silico briquette, the adhesive sheet that is connected with described stationary table, and be located at glass between described adhesive sheet and the described silico briquette, unlike the prior art be, described glass along a side thickness of its width less than opposite side thickness.When the cutting silico briquette, glass is consumptive material, uses once promptly discarded; And adhesive sheet is non-consumptive material, can use always.Glass has the shape to lopsidedness in the specific purpose tool provided by the utility model, and the glass that tilts is fixed between silico briquette and the adhesive sheet, and silico briquette can be realized the silico briquette inclined cut also to lopsidedness.During the steel wire cutting, from the thicker side incision of glass, though in cutting process, can produce the line bow, but can determine the thickness of glass opposite side according to the flexibility of line bow, guarantee under the prerequisite of the wired bow of steel wire, still can not cut glass along thickness direction fully when steel wire leaves glass, make steel wire can not touch adhesive sheet, guarantee the safe in utilization of adhesive sheet.Like this, cut brokenly as the glass of consumptive material, but can not be affected as the adhesive sheet of non-consumptive material, protected the structure of adhesive sheet, the service life of adhesive sheet is secure.
Simultaneously, the structure that only changes glass just can realize inclined cut, does not need existing machine tool hardware is changed, and does not also need to change the existing structure of adhesive sheet, the service life of adhesive sheet is secure, and specific purpose tool provided by the utility model realizes that cost is low.
A kind of preferred embodiment in, described glass is right-angled trapezium along the cross section of its thickness direction.Though the thickness of two sides of glass is different, but the regular shape of gradual change is convenient to fix when adhesive sheet and silico briquette and glass are fixed together, and is easy to realize.
