In the target area of the first cutting wire net, the wire spacing is a preset multiple of the target wire spacing; the preset length is smaller than the length of the main roller in the main roller mechanism.
In one embodiment, the cutting machine comprises a main roller mechanism, a paying-off wheel and a take-up wheel. As shown in fig. 2, fig. 2 shows a schematic structural diagram of a main roller mechanism in an embodiment of the present invention, and the main roller mechanism includes a first main roller 201 and a second main roller 202, which are arranged side by side, and a pay-off reel 203 and a take-up reel 204. A first paying-off guide wheel 205, a second paying-off guide wheel 206 and a third paying-off guide wheel 207 are arranged on one side of the paying-off wheel 203; on one side of the take-up pulley 204, a first take-up guide pulley 208, a second take-up guide pulley 209 and a third take-up guide pulley 210 are provided. The payout and take- up wheels 203, 204 are used to receive a cutting wire, such as a diamond wire. Before cutting the silicon rod 211 shown in fig. 2, first, a cutting line needs to be drawn from the drawing wheel 203 through the first, second, and third drawing guide wheels 205, 206, and 207, and the cutting line needs to be wound around the outlet end of the main roller mechanism from the inlet end of the main roller mechanism to form a wire cut net 212. The wire inlet end is one end of the main roller mechanism, which introduces the cutting wire led out from the second wire releasing guide wheel 206 into the main roller mechanism, and the wire outlet end is one end of the main roller mechanism, which introduces the cutting wire in the main roller mechanism into the third wire receiving guide wheel 210. In the process of cutting the silicon rod 211, the first main roller 201 and the second main roller 202 in the main roller mechanism rotate to drive the cutting line in the cutting line net 212 to run between the inlet end and the outlet end, meanwhile, the silicon rod 211 is fed to the cutting line net 212, and the silicon rod 211 can be cut into a plurality of silicon wafers through the running cutting line. The above is merely an illustrative example, and the specific structure and operation mechanism of the cutting machine may be set according to the requirement, which is not limited by the embodiment.
In this embodiment, in the wiring process of the wire mesh, the wire can be first wired on the wire inlet end of the main roller mechanism to form a first wire mesh, the length of the first wire mesh is a preset length, and the preset length can be much smaller than the length of the main roller. As shown in fig. 3, fig. 3 is a schematic diagram of a first wire cutting net in an embodiment of the present invention, and a plurality of wire grooves 301 are formed on the surface of the main roller at intervals from a wire inlet end to a wire outlet end, and are used for accommodating cutting wires. The user can manually draw the end of the cutting line from the pay-off wheel 203, drag the end of the cutting line, introduce part of the cutting line in the pay-off wheel 203 into the main roller mechanism through the first pay-off guide wheel 205, the second pay-off guide wheel 206 and the third pay-off guide wheel 207, and then wind the cutting line in the wire groove of the incoming line end along the direction extending from the incoming line end to the outgoing line end to form a first cutting line net 302 as shown in fig. 3, and in the process of winding the first cutting line net 302, the user can control the line spacing between two adjacent cutting lines 3022 in the target area 3021 to make the line spacing in the target area be the preset multiple of the target line spacing, where the preset multiple can be 2 times. After the first cutting wire net is formed by winding, the wire head can be fixed in the first cutting wire net, and the winding of the first cutting wire net is completed.
Optionally, the target area comprises a part of the first cutting wire net on the side close to the outlet end. As shown in fig. 3, the target area is located to the right of the first wire cutter web 302 in fig. 3, near the wire outlet end in the main roller mechanism. When the target area is a partial area in the first cut-wire net, the number of cut wires adjusted by a user can be reduced, and it is convenient for the user to fix the wire interval within the target area.
In practical applications, the target area may be any area in the first wire mesh, for example, a partial area formed by the plurality of cutting wires on the side close to the outlet end in fig. 3, a partial area on the side far from the outlet end, or an area located in the middle of the first wire mesh. The target area may be the entire area of the first wire cut web or a partial area of the first wire cut web. The line pitch in the target region may be set according to the target line pitch, for example, when the preset multiple is 2 times, if the target line pitch is X, the line pitch L in the target region is X/2.
Optionally, step 101 may be implemented as follows:
winding partial cutting lines in each wire groove in the wire inlet end in sequence by adopting partial cutting lines led out from a pay-off wheel from the wire inlet end to form an initial cutting wire net;
and adjusting the line spacing in the target area in the initial cutting line net to be a preset multiple of the target line spacing to obtain a first cutting line net.
In one embodiment, the user may first route the wire grooves along the surface of the main roller to form an initial cut wire web having the same length as the first cut wire web, and then adjust the wire pitch in the target area of the initial cut wire web to a preset multiple of the target wire pitch to obtain the first cut wire web. The initial cutting of the wire mesh can be achieved either by a user manually or automatically.
Optionally, starting from the incoming line end, winding the partial cutting lines into each wire slot in the incoming line end in sequence by using the partial cutting lines led out from the pay-off wheel, and the step of forming the initial cutting wire net may include:
arranging an annular traction belt at the target position of the main roller mechanism; an annular traction belt surrounds the two main rollers;
fixing the end of the partial cutting line on an annular traction belt;
and controlling the main roller mechanism to rotate so as to drive the annular traction belt to rotate, so that part of the cutting wire is wound in each wire groove of the wire inlet end to form an initial cutting wire net.
Referring to fig. 4, fig. 4 is a schematic view illustrating another first cutting wire net according to an embodiment of the present invention, wherein the target position is a position where the endless traction belt 401 is located in fig. 4, the target position is close to the wire inlet end and is a predetermined distance away from the wire inlet end, and the predetermined distance can be flexibly adjusted according to the length of the first cutting wire net. During laying of the first cutting wire web, a user may first set an endless belt 401, which is disposed around the first main roll 201 and the second main roll 202, at a target position of the main roll mechanism, and the endless belt 401 may rotate along with the first main roll 201 and the second main roll 202 during rotation of the first main roll 201 and the second main roll 202. In the wiring process, a user can fix the wire end led out from the paying-off wheel 203 on the annular traction belt 401 through an adhesive tape or other bonding pieces, then the first main roller 201 and the second main roller 202 are controlled to rotate to drive the annular traction belt 401 to rotate, in the rotating process of the annular traction belt 401, partial cutting wires can be led out from the paying-off wheel 203 through the wire end, and the led partial cutting wires are sequentially arranged in the wire grooves in the surface of the wire inlet end along the wire grooves in the surface of the wire inlet end to form an initial cutting wire net. In the initial wire web, the cutting wires are uniformly arranged in wire grooves 301 in the surface of the main roller.
After routing to form the initial cut wire web, the user may remove the endless pull belt, select a target area in the initial cut wire web, manually adjust the wire pitch in the target area to a preset multiple of the target wire pitch, and then secure the wire head secured to the endless pull belt in the initial cut wire web to form the first cut wire web.
In the embodiment of the invention, the initial cutting wire net is arranged through the annular traction belt, so that the automatic arrangement of the initial cutting wire net can be realized, and the arrangement efficiency of the whole cutting wire net can be improved.
And 102, fixing the line spacing in the target area.
In this embodiment, after the first cutting wire mesh is formed by winding, the wire spacing in the target area may be fixed. As shown in fig. 3, a plurality of cutting lines in the target region may be connected using a fixing member 303 to fix the relative positions between the plurality of cutting lines to fix the line interval between the plurality of cutting lines. The fastener 303 may be an adhesive tape or other type of fastener. The fixing member 303 is used to make the first cutting wire net always have a wire interval of a preset multiple of a target wire interval in the process of moving the first cutting wire net along the main roll. The fixing member 303 may fix a line interval between partial or all of the cutting lines in the target region, which is not limited in this embodiment.
Alternatively, in fixing the line pitch within the target region, the line pitch between the continuous plurality of cutting lines in the target region may be fixed. As shown in fig. 3, when the target area is a partial area of the first wire net near the outlet end, the wire pitch between the continuous cutting wires can be fixed. Wherein the number of the continuous cutting lines is not less than three. In practical application, only the line spacing between partial cutting lines in the first cutting line net is fixed, so that user operation can be reduced, and wiring efficiency is improved.
And 103, controlling the main roller mechanism to rotate, so that the first cutting wire net runs to the wire outlet end of the main roller mechanism, and driving the cutting wires in the pay-off wheel to form a second cutting wire net with the wire spacing as the target wire spacing between the wire inlet end and the first cutting wire net.
In this embodiment, after fixing the line spacing in the target area, a user may start the main roller mechanism to rotate the first main roller 201 and the second main roller 202 shown in fig. 2, and since the cutting lines in the first cutting line net are wound in the line grooves on the surfaces of the first main roller 201 and the second main roller 202, the first main roller 201 and the second main roller 202 may drive the first cutting line net to move from the line inlet end to the line outlet end in the rotating process. In the process that the first cutting wire net runs towards the wire outlet end, the cutting wire in the first cutting wire net is connected with the cutting wire in the paying-off wheel 203, so that the cutting wire in the paying-off wheel 203 can be driven to wind towards the main roller mechanism, and the wire distance of the second cutting wire net formed by winding is the target wire distance because the wire distance in the target area is a preset multiple of the target wire distance. When the first cutting wire net runs to the wire outlet end, the main roller mechanism is stopped, and the winding of the second cutting wire net is completed. At this time, the second cutting wire net covers the other area of the main roller mechanism than the area where the first cutting wire net is located.
Alternatively, when controlling the rotation of the main roller mechanism, the method may include: the linear speed of the main roller is controlled to be positively correlated with the length of the second wire web.
In one embodiment, during the routing of the second wire web, the user may adjust the linear speed of the main roller, gradually increasing the linear speed of the main roller as the length of the second wire web increases. The length of the second cutting wire net is the length from the wire inlet end to the side, close to the wire inlet end, of the first cutting wire net in the process that the first cutting wire net runs towards the wire outlet end. For example, the linear velocity of the main roll can be controlled by the formula v ═ ax + b, where the symbol v is the linear velocity of the main roll, x is the length of the second wire cut web, a is the rate of change of the linear velocity of the main roll, and b is the tuning parameter. In practical applications, the linear speed of the main roller may be controlled to be directly related to the length of the second wire mesh in other manners, which is not limited in this embodiment.
In practical application, in the process of laying the second cutting wire net, the linear speed of the main roller is controlled to be positively correlated with the length of the second cutting wire net, so that the wiring of the second cutting wire net can be completed quickly, and the cutting efficiency can be improved.
Optionally, when controlling the main roller mechanism to rotate, the method may further include: the tension of the cutting wire is controlled to be positively correlated with the length of the second wire web.
In one embodiment, during the routing of the second wire net, the user may gradually increase the tension of the cutting wire in the second wire net as the length of the second wire net increases, so that the tension of the cutting wire in the second wire net is positively correlated with the length of the second wire net. For controlling the tension of the cutting line, the control of the linear velocity of the main roller can be referred to, and this embodiment will not be described in detail.
In this embodiment, during the wiring process of the second wire cutting net, the linear velocity of the main roller may also be controlled to be not lower than 3 meters per second (m/s), or the linear velocity of the main roller may be controlled to be not lower than 3m/s and not higher than 5 m/s. Meanwhile, the tension of the cutting line in the second wire mesh can be controlled to be not less than 2 newtons (N), or the tension of the cutting line in the second wire mesh can be controlled to be not less than 2N and not more than 4N. And controlling the linear speed of the main roller to be not less than 3m/s and not more than 5m/s to realize the fast and stable wiring of the second wire cutting net, and similarly, controlling the tension of the cutting wires in the second wire cutting net to be not less than 2N and not more than 4N to realize the fast and stable wiring of the second wire cutting net.
And 104, guiding the cutting line in the first cutting line net into the take-up pulley, so that the second cutting line net covers the wire outlet end.
In this embodiment, after the first cutting wire net is moved to the wire outlet end, the user can guide the cutting wire in the first cutting wire net into the wire take-up wheel 204, so that the second cutting wire net covers the wire outlet end, and at this time, the second cutting wire net covers the area of the whole main roller mechanism where the cutting wire needs to be wound, i.e., the cutting wire net 212 in fig. 2, which can be used for cutting silicon wafers. For example, after the first cutting wire net runs to the wire outlet end, the user first stops the main roller mechanism and removes the fixing member 302, then pulls the wire head in the first cutting wire net to the wire take-up pulley 204 through the first wire take-up guide pulley 208, the second wire take-up guide pulley 209 and the third wire take-up guide pulley 210, fixes the wire take-up pulley 204, restarts the main roller mechanism and starts the wire take-up pulley, so that the cutting wire in the first cutting wire net runs to the wire take-up pulley 204 until all the cutting wires in the first cutting wire net are received in the wire take-up pulley 204, and stops the main roller mechanism and the wire take-up pulley, at this time, the second cutting wire net covers the whole main roller, and the wiring of the cutting wire net is completed.
In practical application, the distance between two adjacent wire grooves in the surface of the main roller is fixed, in the wiring process of a cutting wire net, if the wire distance between cutting wires in the cutting wire net to be laid is determined to be larger than the groove distance between two adjacent wire grooves according to the thickness requirement of a silicon wafer, in the wiring process, a user needs to manually use a device to dial wires, the wire distance between the cutting wires in the wiring process is controlled, and wiring is completed. Generally, the length of a cutting wire net is large, the efficiency is low during manual wire poking, and certain safety risk exists during manual wire poking. Meanwhile, the cutting lines in the cutting line net are dense, so that the wiring quality is difficult to ensure by a manual line shifting mode.
In summary, in the embodiment, in the wiring process of the cutting wire net, the cutting wire led out from the pay-off wheel is used, the first cutting wire net with the preset length is formed on the wire inlet end of the main roller mechanism, the wire spacing in the target area in the first cutting wire net is fixed, the wire spacing in the target area is a preset multiple of the target wire spacing, then the main roller mechanism is controlled to rotate, the first cutting wire net is made to run to the wire outlet end of the main roller mechanism, so as to drive the cutting wire in the pay-off wheel to form the second cutting wire net with the wire spacing as the target wire spacing between the wire inlet end and the first cutting wire net, the cutting wire in the first cutting wire net is led into the take-up wheel, and the second cutting wire net covers the wire outlet end. The wire arrangement is firstly carried out to form a first cutting wire net, the wire spacing of the middle part of the first cutting wire net is controlled to be a preset multiple of the target wire spacing, then the first cutting wire net is driven to operate through the main roller mechanism, the wire arrangement is automatically carried out in the main roller mechanism to form a second cutting wire net with the target wire spacing, compared with the manual wire arrangement of the second cutting wire net, the wire arrangement efficiency is higher, and the wire arrangement time can be shortened. Meanwhile, manual wire shifting can be avoided, and safety and accuracy in the wiring process are improved.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
