Specifically, the first cutting wheel 1231 and the second cutting wheel 1232 are located forward of the cutting location (near the waiting location) and are disposed in a second direction, i.e., the first cutting wheel 1231 is on the left and the second cutting wheel 1232 is on the right, the first guide wheel 1261 is located on the rear side of the first cutting wheel 1231, and the second guide wheel 1262 is located on the rear side of the second cutting wheel 1232 and is located on the right side of the first guide wheel 1261.

The cutting coping saw 125 is laid along the second direction, and the former silicon rod that corresponding processing station department was born by silicon rod load-bearing device (the silicon rod load-bearing device includes silicon rod avris clamping mechanism 15 and first silicon rod tip clamping mechanism 16) is horizontal place (the axial lead of former silicon rod is laid along the first direction), consequently, for the horizontal cutting that realizes former silicon rod, the length of cutting coping saw with the size looks adaptation of the terminal surface of former silicon rod, for example, the length of cutting coping saw will be more than or equal to the terminal surface width of former silicon rod.

Further, as described above, in order to ensure the stability of the raw silicon rod during the transverse cutting operation and to avoid chipping or cutting ripples of the cutting surface or the like due to mutual displacement between the first and second silicon rods formed by cutting, the first end clamp in the first silicon rod end clamping mechanism is brought into contact with at least the end surface of the first silicon rod to be formed, for example, the first end clamp is brought into clamping contact with an upper portion of the end surface of the raw silicon rod (the upper portion of the end surface of the raw silicon rod covers only the end surface of the first silicon rod to be formed), or the first end clamp is brought into clamping contact with a large portion or even all of the end surface of the raw silicon rod (the large portion or even all of the end surface of the raw silicon rod covers the end surface of the second silicon rod to be formed and the end surface of the first silicon rod), in which case the first end clamp may interfere with the cutting wire saw during the transverse cutting operation. Therefore, in practical applications, as shown in fig. 4, after the carrying device is driven to move the square silicon rod to the cutting section and the front end surface of the square silicon rod is close to the cutting wire saw 125, the first silicon rod end clamping mechanism 16 is driven to clamp the two end surfaces of the square silicon rod, at this time, the cutting wire saw 125 is located inside the first end clamping member of the first silicon rod end clamping mechanism 16, and during the transverse cutting operation, the cutting wire saw 125 does not interfere with the first end clamping member of the first silicon rod end clamping mechanism 16, so as to ensure smooth execution of the transverse cutting operation.

As shown in fig. 1 and 3, the first cutting wheel, the second cutting wheel, the first guide wheel, and the second guide wheel provided on the four branches of the X-shaped mounting structure as the cutting support 122 may form a quadrangle, which may be, for example, a rectangle, a trapezoid, or another trapezoid.

In addition, the first guide wheel and the second guide wheel are used for reversing or guiding the cutting wire (the guide wheels can also be called as reversing wheels or transition wheels), in some embodiments, the first guide wheel and the second guide wheel can be used for adjusting the tension of the cutting wire (the guide wheels for adjusting the tension can also be called as tension wheels), for example, the first guide wheel or the second guide wheel can be used as a tension wheel, and the tension of the closed loop cutting wire can be adjusted by adjusting the first guide wheel or the second guide wheel. Taking the first guide pulley as an example of a tension pulley, a tension adjusting mechanism may be provided for the first guide pulley, and the tension adjusting mechanism may be used to drive the first guide pulley to move on the corresponding branch of the X-shaped mounting structure as the cutting support 122 so as to adjust the tension of the closed loop cutting line. For example, driving a first guide wheel towards the end on the respective bifurcation increases the tension of the closed loop cutting line; the first guide wheel is driven to move on the respective bifurcation towards the central crossing position of the X-shaped mounting structure, reducing the tension of said closed loop cutting line. In some embodiments, the tensioning mechanism may be, for example, a guide rail, a lead screw, and a drive motor.

In certain embodiments, the cutting device further comprises: and the distance adjusting mechanism is used for driving the cutting wheels to move relative to the cutting frame along the direction vertical to the wheel surfaces of the cutting wheels. The cutting device can realize the switching of the cutting line between different cutting grooves of the cutting wheel based on the distance adjusting mechanism, or adjust the position of the cutting wire saw to change the cutting position (or the processing specification) relative to the silicon rod.

In some implementations, the carrier for carrying the cutting wheels and the guide wheels is, for example, a cutting support, the distance adjustment mechanism can be used for driving the cutting support to move along the perpendicular direction of the wheel surface of the cutting wheel as a whole, and the guide wheels and the cutting wheels jointly follow the cutting support to move along the perpendicular direction (i.e., the vertical direction) of the wheel surface of the cutting wheel, in this state, the cutting wheels and the guide wheels are relatively static, i.e., the position relationship between the guide wheels and the cutting wheels is unchanged. At this time, the distance adjusting mechanism is used for adjusting the cutting position of the at least one wire cutting saw in the at least one wire cutting unit relative to the silicon rod.

In some implementations, each cutting wheel has at least two cutting slots, with different cutting slots being parallel to each other and having a cutting offset between them in the direction of the perpendicular to the wheel face of the cutting wheel. When the distance adjusting mechanism is used for driving the cutting wheels in the wire cutting unit to move relative to the cutting support, the position of the cutting wire wound on the wire grooves on the cutting wheels can be changed. In certain implementations, multiple cutting wheels may be attached to a carriage, for example, wherein the carriage is movably mounted to the cutting support and is driven by the pitch adjustment mechanism to move in a direction perpendicular to the cutting wheel faces.

When the at least one distance adjusting mechanism is used for changing the cutting line to wind around the cutting line grooves of the plurality of cutting wheels, in an actual scene, the cutting line grooves corresponding to the cutting lines before and after the groove changing can be predetermined, for example, the position of the cutting line before the groove changing is the cutting line groove a1, the cutting line after the groove changing is wound around the cutting line groove a2, the displacement of the at least one distance adjusting mechanism for driving the plurality of cutting wheels to move is determined based on the cutting offset between the cutting line groove a1 and the cutting line groove a2, that is, the displacement is set to the cutting offset between the cutting line groove a1 and the cutting line groove a2, and the distance adjusting mechanism can be used for changing the cutting line from the cutting line groove a1 to the cutting line groove a 2; it should be noted that the direction of the plurality of cutting wheels in the driving wire cutting unit of the at least one distance adjusting mechanism moving along the direction of the perpendicular to the wheel surfaces of the cutting wheels is the direction of the cutting wire groove a2 pointing to the cutting wire groove a1, and the cutting position of the cutting wire saw in the space is not changed after the groove is changed, so that the silicon rod can be cut according to the preset cutting amount without the step of further calibrating the positions of the cutting wheels or other components, and the groove changing process is simplified.

In some embodiments, the pitch adjustment mechanism comprises: the screw rod is arranged along the orthogonal direction of the wheel surfaces of the cutting wheels and is in threaded connection with the mounting structures of the plurality of cutting wheels; and the screw rod driving source is used for driving the screw rod to rotate. In some embodiments, the pitch mechanism comprises: the telescopic piece is arranged along the orthogonal direction of the cutting wheel surface and is associated with the mounting structures of the plurality of cutting wheels; and the telescopic piece driving source is used for driving the telescopic piece to do telescopic motion along the orthogonal direction of the wheel surface of the cutting wheel. In some embodiments, the pitch adjustment mechanism comprises: the distance adjusting rack is arranged along the orthogonal direction of the wheel surfaces of the cutting wheels and is associated with the mounting structures of the cutting wheels; the transmission gear is meshed with the distance adjusting rack; and the gear driving source is used for driving the transmission gear to rotate.

In certain embodiments, the cutting device further comprises: and the wire saw adjusting mechanism is used for adjusting the wire length of the cutting wire saw so as to be matched with the part to be cut of the square silicon rod to be cut (namely the end surface of the square silicon rod). For example, when the to-be-cut part of the square silicon rod to be cut is large, the wire length of the cutting wire saw can be increased; when the part to be cut of the square silicon rod to be cut is small, the length of the cutting wire saw can be shortened.
