Abstract
The utility model discloses a guide stripe for multi-line cutting of a silicon crystal. The guide stripe is a stripe body, the cross section of the stripe body can be a trapezoid and a right triangle, the trapezoid can be an isosceles trapezoid, and the right triangle can be an isosceles right triangle or a right triangle with a 30-degree acute angle. Jumping and side slip of a steel wire at a cutting initial stage can be effectively improved, wire breakage rate is reduced, and cutting process stability is ensured.
Description
Technical field
The utility model relates to for silicon crystal multi-wire saw process, particularly suitable photovoltaic industry silicon single crystal or policrystalline silicon silicon chip cutting process.
Background technology
In the industry field such as electronics, photovoltaic, the application of silicon crystal has become the trend of development.Particularly, in photovoltaic industry, multi-wire saw technology has generally applied to the processing of silicon chip.In the time of multi-thread processing feed, cutting steel wire is easy to break away on silicon crystal surface.Known gib block generally adopts rectangular design, in initial cut process, can avoid steel wire to break away, but because the sectional area of rectangle gib block is excessive, cause cutting initial stage steel wire waste and increase, the more hidden danger such as wire jumper that also can produce of produced simultaneously gib block chip.
Utility model content
The purpose of this utility model is to avoid the weak point in above-mentioned background technology and a kind of gib block for silicon crystal multi-wire saw process is provided.
The purpose of this utility model is achieved in that a kind of gib block for silicon crystal multi-wire saw, and described gib block 1 is a bar body, and the cross section 2 of bar body is triangle.Described triangle is right angled triangle.Described right angled triangle is isosceles right triangle.An acute angle of described right angled triangle is 30 °.
For a gib block for silicon crystal multi-wire saw, described gib block 1 is a bar body, and the cross section 2 of bar body is trapezoidal.Described trapezoidal be isosceles trapezoid.
The utility model tool compared with background technology has the following advantages:
1, the utility model can reduce cutting area, reduces the use of steel wire and the generation of chip.
2, the utility model can effectively improve in cutting initial stage steel wire wire jumper and sideslip phenomenon, lowers outage, ensures that cutting process is stable.
3, the utility model can be saved material.
Brief description of the drawings
Fig. 1 is the structural representation of first detailed description of the invention of the utility model;
Fig. 2 is the cross sectional representation of second detailed description of the invention of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
As shown in Figure 1, described gib block 1 of the present utility model is a bar body, and the cross section 2 of bar body is triangle.Further improve, described triangle is right angled triangle or isosceles right triangle.In the middle of embodiment, an acute angle of right angled triangle is 30 °.
As shown in Figure 2, the cross section 2 of guiding rule body of the present utility model is trapezoidal.In the middle of embodiment, described trapezoidal be isosceles trapezoid.
When work, the bottom surface of gib block is sticked on silicon crystal to be cut, first many lines of cut contact and compress the upper top of gib block, because gib block cross section is triangle, the traffic direction of line of cut and the length direction of gib block are perpendicular, make contacting as some contact between line of cut and the upper top of gib block, and Cutting Drag is little, effectively improve in cutting initial stage steel wire wire jumper and sideslip phenomenon, lower outage.When gib block cross section is trapezoidal, can reduce equally cutting area, and produce same technique effect.
