Abstract
The utility model relates to a main roller for cutting silicon rods belongs to silicon chip production technical field, and this home roll includes the home roll body, is provided with the tooth's socket that the location line of cut was used in home roll body periphery, tooth's socket bottom be provided with the constant head tank, the notch of constant head tank is connected with the cell wall of tooth's socket, contained angle alpha between the both sides wall of constant head tank is greater than the contained angle beta of two cell walls of tooth's socket, perpendicular distance between the notch of constant head tank and the notch of tooth's socket is 30um, the width of rebate of tooth's socket is 60um, the radius of line of cut is 50um, the line of cut is arranged in the tooth's socket and removes along with the rotation of home roll body, the both sides of line of cut contact with the cell wall of both sides respectively, the bottom of line of cut contacts with the lateral wall of constant head tank, then, area of contact and the frictional force of line of cut in the tooth's socket all increases, the line of cut is more stable at the removal in -process, the wire jumper and the wobbling condition are showing and are reducing, thereby the quality of life with the cutting silicon chip of line of cut has been improved.
Description
Technical field
This utility model belongs to silicon chip production technical field, relates to a kind of incisory home roll of silicon rod.
Background technology
Method conventional during cutting silicon rod is to cut by being wound with the rubber roll of steel wire, and the main purposes of rubber roll is
Being wound around steel wire, be wound around steel wire and lean on teeth groove, steel wire has diamond mortar, silicon rod passes through on the steel wire of movement in moving process
Silicon rod is cut into silicon chip by diamond, and the home roll in rubber roll rotates and drives steel wire to move, the formation between adjacent two home rolls
One group of wire.
Teeth groove in home roll is typically all V-groove structure now, general about 30 ° of angle, during actual production uses
Find to be very easy to wire jumper, be also susceptible to swinging back and forth of steel wire.Wire jumper phenomenon is that wherein a line has jumped to another tooth
In groove, there is broken string situation after mutually wearing and tearing in two steel wires in a teeth groove, and home roll is directly scrapped；If steel wire carrys out backswing
Dynamic, cause the spacing between steel wire unstable, the silicon chip uneven distribution cut out, yields is the lowest.Accordingly, it would be desirable to existing
The structure having home roll improves.
Utility model content
The shortcoming that this utility model overcomes prior art, it is provided that a kind of incisory home roll of silicon rod, this home roll can
Increasing the contact area between line of cut and teeth groove and frictional force, line of cut is more stable when moving with home roll, greatly reduces
Wire jumper and the phenomenon swung back and forth, the quality of the service life of line of cut and cutting silicon chip all increases.
The concrete technical scheme of the present invention is:
A kind of incisory home roll of silicon rod, including home roll body, is provided with positional dissection line in home roll body periphery
Teeth groove, key point is, described gullet base is provided with locating slot, and the notch of locating slot is connected with the cell wall of teeth groove, location
Angle α between the two side of groove is more than the angle β of two cell walls of teeth groove.
The number of degrees of described angle α are 90 °.
Described angle β is 30 °.
Vertical dimension between notch and the notch of teeth groove of described locating slot is 30um.
The width of rebate of described teeth groove is 60um.
The radius of described line of cut is 50um.
The invention has the beneficial effects as follows: teeth groove is improved by this utility model, the bottom land of teeth groove is set to taper, and
And the drift angle of teeth groove is more than the angle between the cell wall of teeth groove both sides, when line of cut is positioned in teeth groove, not only both sides can touch
The cell wall of teeth groove, bottom also is able to touch the bottom land both sides of teeth groove, and the rubbing surface between line of cut and teeth groove is compared to improvement
Being greatly increased, frictional force produced by line of cut is increased by teeth groove the most therewith before, and this frictional force is i.e. to drive line of cut to move
Initial driving force, frictional force and the increase of bond area so that line of cut is more stable when movable type, it is possible to avoid wire jumper and
The phenomenon swung back and forth occurs, and the service life of line of cut increases, and the silicon wafer thickness that cutting obtains is more uniform, and yields can
Stable in higher level.
Accompanying drawing explanation
Fig. 1 is the structural representation of home roll in this utility model specific embodiment.
Fig. 2 is the enlarged diagram of A in Fig. 1.
In accompanying drawing, 1, home roll body, 2, teeth groove, 3, locating slot, 4, cell wall, 5, line of cut.
Detailed description of the invention
This utility model relates to a kind of incisory home roll of silicon rod, including home roll body 1, in the peripheral setting of home roll body 1
There is the teeth groove 2 of positional dissection line 5, bottom described teeth groove 2, be provided with the groove of locating slot 3, the notch of locating slot 3 and teeth groove 2
Wall 4 is connected, and the angle α between the two side of locating slot 3 is more than the angle β of two cell walls 4 of teeth groove 2, the cross section of locating slot 3
Shape can be triangle, trapezoidal or polygon.
Specific embodiment, as depicted in figs. 1 and 2, the cross sectional shape of locating slot 3 is chosen as triangle, and upper end is locating slot 3
Notch, the number of degrees of the angle α between the two side of triangle are 90 °, and the angle β between two cell walls 4 of teeth groove 2 is 30 °,
Vertical dimension between notch and the notch of teeth groove 2 of locating slot 3 is 30um, and this distance can effectively ensure that when line of cut moves
Being limited in teeth groove 2, the width of rebate of teeth groove 2 is 60um, and the radius of line of cut 5 is 50um, and the line of cut 5 of this radius is at tooth
In groove, can either contact with two cell walls 4, can contact with the sidewall of locating slot 3 again, thus increase connecing of line of cut 5
Contacting surface is amassed and frictional force, is finally reached stable purpose.
This utility model increases line of cut contact area in teeth groove by arranging angle more than the locating slot of teeth groove
And frictional force, line of cut is more stable in motor process, greatly reduces wire jumper and the situation swung back and forth, making of line of cut
Being obviously prolonged with the life-span, silicon rod is through the dissection of stable line of cut, and its thickness is more uniform, and silicon chip product quality is relatively
High.
