When the driving gear 253 is driven to rotate reversely by the driving power source 254, the driving gear 253 rotating reversely can drive the rotating gear 252 to rotate in the forward direction, so as to drive the supporting platform 21 to rotate in the forward direction.

In the embodiment shown in fig. 4, the rotation of the support table by means of the rotary drive unit may cause the first group of silicon rod carrying structures and the second group of silicon rod carrying structures on the support table 21 to be interchanged in position, i.e. each silicon rod carrying structure 23 of the first group of silicon rod carrying structures is transferred from the loading and unloading zone to the cutting zone and each silicon rod carrying structure 23 of the second group of silicon rod carrying structures is transferred from the cutting zone to the loading and unloading zone, or each silicon rod carrying structure 23 of the first group of silicon rod carrying structures is transferred from the cutting zone to the loading and unloading zone and each silicon rod carrying structure 23 of the second group of silicon rod carrying structures is transferred from the loading and unloading zone to the cutting zone.

In the embodiment shown in fig. 6, when the rotational drive unit is used to drive the support table to rotate, the group of silicon rod carrying structures on the support table 21 can be switched between the loading and unloading region and the cutting region, i.e. each silicon rod carrying structure 23 in the group of silicon rod carrying structures is switched from the loading and unloading region to the cutting region, or each silicon rod carrying structure 23 in the group of silicon rod carrying structures is switched from the cutting region to the loading and unloading region.

Of course, the rotary drive unit can be varied in other ways. For example, in some embodiments, the rotational driving unit may include a rotational shaft and a rotational power source for driving the rotational shaft to rotate, and the rotational power source may be, for example, a rotational motor or the like.

In order to switch any one group of silicon rod bearing structures on the supporting platform 21 between the loading and unloading area and the cutting area, the rotation driving unit needs to drive the supporting platform 21 to rotate by a preset angle. In the embodiment shown in fig. 4 and 6, the handling zone and the cutting zone differ by 180 °, so that the preset angle of rotation required by the rotary drive unit may be, for example, 180 °. In some embodiments, the preset angle at which the rotation drive source in the rotation drive unit is rotated may be set to 180 °. In some embodiments, a corresponding angle detection component may be added to detect the rotation angle of the supporting platform 21 after being driven, and send out detection information to stop the rotation driving source when detecting that the rotation angle of the supporting platform 21 reaches 180 °.

It should be noted that, when a plurality of silicon rod carrying devices are disposed on the silicon rod processing platform of the multi-station squaring apparatus, the supporting platform of the silicon rod carrying device 2 may be changed to some extent. Returning to fig. 1 and 2, two silicon rod carrying devices 2 are arranged on the silicon rod processing platform of the multi-station squaring device, and the two silicon rod carrying devices 2 are arranged along a first direction. In this embodiment, the support platform 21 has a waisted portion (see 210 in fig. 4 and 6). By the design, the two silicon rod bearing devices 2 can be staggered and switched between the two bearing tables 21 in the switching process (as shown in a schematic diagram in fig. 7), so that the space redundancy is greater than that of a common bearing table, and the space of the machine base in the first direction occupied by the arrangement of the two silicon rod bearing devices along the first direction is smaller than that of the machine base in the first direction occupied by the arrangement of the two silicon rod bearing devices with the common bearing table, so that the multi-station squaring equipment can be more compact as a whole, the occupied space of the whole machine is small, and the equipment cost is saved.

In order to ensure that the supporting platform 21 can rotate according to a preset angle, in the silicon rod bearing device of the present application, the supporting platform switching mechanism further includes a positioning structure for positioning after the supporting platform rotates by a preset angle to form a locking state.

The positioning structure may include: the first positioning part is arranged on the bearing platform; and the second positioning part is arranged on the machine base. The first positioning part and the second positioning part are matched to realize the positioning of the bearing platform.

In some embodiments, in the positioning structure, the first positioning portion may be, for example, a positioning hole or a positioning groove, and the second positioning portion may be, for example, a positioning pin or a positioning protrusion.

As shown in fig. 3 to 5, the positioning structure includes: a detent groove 221 and a detent pin 222. The bottom surfaces of the end portions of the two opposite sides of the supporting platform 21 are respectively provided with a positioning groove 221, the outer side of the machine base 1 is provided with a positioning pin 222, and the positioning pin 222 can be fixed on the machine base 1 through a mounting frame. In a specific application, the positioning slot 221 may be a ball socket, for example, and the positioning pin 222 may be a ball tip engaged with the ball socket, for example. Furthermore, a zenith opening can be additionally arranged at the top of the ball socket, and correspondingly, a tip matched with the zenith opening can be arranged at the top of the ball tip, so that accurate positioning can be realized.

In some embodiments, for the positioning structure, the ball tip as the positioning pin 222 may be further configured with an elastic member, such as a spring, and the ball tip may be raised upward by the elastic member in a non-pressed state, and may be compressed and contracted in a pressed state. Therefore, when the supporting platform 21 is driven by the rotation driving unit to rotate, the ball pin is pressed to be in a contracted state, and when the ball socket of the supporting platform 21 is rotated, and no obstacle exists above the ball pin to be in a non-pressure state, the ball pin can be protruded upwards under the action of the elastic component and enter the ball socket, so that positioning is realized.

In some embodiments, for the locating feature, the locating slot and the locating pin are configured to be magnetic. Taking the positioning groove as a ball socket and the positioning pin as a ball pin as an example, one of the ball socket and the ball pin may be provided with a magnetic material and the other may be a metal that can be magnetically attracted, or the ball socket and the ball pin may be provided with opposite magnetic materials, although in such an embodiment, the ball pin may also be provided with a telescopic design. In this way, when the supporting platform 21 is driven by the rotation driving unit to rotate and the ball socket approaches the ball tip, the ball tip is attracted to extend out of the ball socket and protrude into the ball socket due to opposite attraction, so that positioning is realized.

Therefore, by means of the positioning structure, the bearing platform can be controlled by the rotation driving unit, the rotation angle range is guaranteed to accord with the preset angle after the rotation driving unit rotates, the bearing platform can be in a locking state after the rotation driving unit rotates, and follow-up operation is facilitated. In addition, in view of the fact that the precise rotation of the supporting platform can be realized by the positioning structure, in some embodiments, the precise preset angle for the rotation driving unit or the arrangement of a corresponding angle detection component and the like can be omitted, thereby further simplifying the structure and reducing the cost.

The silicon rod bearing device comprises a bearing platform and is characterized in that at least one group of silicon rod bearing structures are arranged on the bearing platform, and each group of silicon rod bearing structures comprises at least one pair of silicon rod bearing structures.

As shown in fig. 3 to 6, the silicon rod carrying structure 23 is used for carrying vertically placed silicon rods, including silicon rods to be cut and cut silicon rods.

In this embodiment, the silicon rod supporting structure 23 further includes a silicon rod supporting platform 231 and a skirt supporting structure 232.

The silicon rod support 231 is used for supporting the silicon rod and making the silicon rod stand, that is, the bottom of the silicon rod is located on the silicon rod support 231. In a specific implementation, the silicon rod bearing table 231 may be a circular table surface or a square table surface.

The edge skin jacking structure 232 is arranged at the periphery of the silicon rod bearing table 231 and used for jacking the edge skin formed after the silicon rod to be cut borne by the silicon rod bearing table 231 is cut by the linear cutting device, wherein the main body part of the silicon rod to be cut after being cut is borne by the silicon rod bearing table 231.

Generally, the section of the silicon rod to be cut is circular, and the section of the cut silicon rod is rectangular, that is, the cut silicon rod has four vertical sections and four connecting prism surfaces, so that the cut silicon rod and four edges are formed after the cut silicon rod is cut and squared by the linear cutting device. Therefore, the silicon rod supporting table 231 is provided with a skirt supporting structure 232 at each of four sides thereof. As shown, the edge skin jacking structure 232 may include ejector rods, that is, ejector rods 232 are disposed on four sides of the silicon rod bearing table 231, wherein the number of the ejector rods on each side may be two.

The extending height of the top rod 232 is consistent with the height of the bearing surface of the silicon rod bearing table 231. When the wire cutting device performs cutting on the silicon rod to be cut on the silicon rod bearing structure 23, the ejector rod 232 can eject the corresponding flaw strip, so that the situation that the cutting wire saw in the wire cutting device breaks the edge when penetrating out of the silicon rod to be cut can be effectively prevented, and the flaw strip can be prevented from falling and overturning.

In certain embodiments, the flaw-piece jacking structure 232 comprises a jacking leg that is of a fixed design. For example, the bottom of the top rod 232 is fixed by welding, or the top rod 232 is fixed by screwing (direct screwing or fixing by a nut).

In certain embodiments, the curb jacking structure 232 comprises a ram that is of an adjustable design. For example, the mounting portion of the top rod is provided with an adjusting groove 233, when the size of the silicon rod to be cut is large, the top rod 232 is adjusted and fixed on the outer side of the adjusting groove 233 to expand the jacking range, and when the size of the silicon rod to be cut is small, the jacking 232 is adjusted and fixed on the inner side of the adjusting groove 233 to reduce the jacking range.

However, the rimmer jacking structure 232 is not so limited, and in some embodiments, for example, the rimmer jacking structure may include a movable jacking member and a locking control member. The movable jacking part comprises a movable base connected to one side surface of the silicon rod bearing structure, a jacking part extending upwards from the movable base, and a power generation structure for providing the jacking part to move up and down. In one embodiment, the movable base may be, for example, a planar plate structure adapted to a side surface of the silicon rod carrying structure, but not limited thereto, and the movable base may also be, for example, a curved plate structure or other special-shaped structure. The top support part is at least two top rods extending upwards from the movable base, but not limited to this, and the top support part may also be a top plate or a top pillar extending upwards from the movable base, for example. The power generating structure comprises two support legs arranged on the movable base and two springs respectively sleeved on the two support legs, but not limited thereto, and the power generating structure can also adopt structures such as a torsion spring, an elastic sheet and the like. The support legs and the connected ejector rods can move up and down relative to the silicon rod bearing structure by utilizing the elasticity of the springs. In the present embodiment, the locking control member is used for controlling the movable jacking member in a locking state when the movable jacking member abuts against the bottom of the silicon rod to be cut, and in an implementation manner, the locking control member may be, for example, an electromagnetic lock. In an initial state, the ejector rod is exposed on the bearing surface of the silicon rod bearing structure under the action of the support legs and the springs, when a silicon rod to be cut is placed, the ejector rod overcomes the elasticity of the springs to move downwards after being pressed by the silicon rod to be cut until the silicon rod to be cut is completely placed on the bearing surface of the silicon rod bearing structure, at the moment, the electromagnetic lock serving as the locking control piece is electrified, and the electromagnetic lock tightly adsorbs the movable base in the movable jacking piece through strong magnetic force generated by an electromagnetic generating principle, so that the ejector rod is controlled in a locking state. When the linear cutting device carries out evolution cutting on the silicon rod to be cut born by the silicon rod bearing structure corresponding to the cutting area in the silicon rod conversion device, the movable jacking piece in the locking state can jack and support the corresponding flaw-piece, the situation that the cutting wire net in the linear cutting unit is broken when penetrating out the silicon rod to be cut can be effectively prevented, and the flaw-piece can be prevented from falling, overturning and the like.

In the present application, on the one hand, the silicon rod bearing structure 23 can follow the supporting platform 21 to switch between the loading and unloading area and the cutting area, and on the other hand, the silicon rod bearing structure 23 also needs to drive the borne silicon rod to be cut to rotate so as to adjust the surface to be cut.

The silicon rod carrying means in the present application can also be designed to be able to move in a self-rotating manner, for example, the silicon rod carrying means has a rotary shaft with respect to the conveying body to enable a self-rotating movement, so that the silicon rod carrying means and the silicon rod thereon can rotate together after the silicon rod carrying means carries the silicon rod. Further, the contact surfaces of the silicon rod carrying structure (the contact surface of the silicon rod carrying table and the contact surface of the flaw-piece jacking structure) for contacting with the silicon rod have damping so as to provide a certain friction force capable of driving the silicon rod.

In the present application, a silicon rod rotation mechanism is assigned to each pair of silicon rod carrying structures, i.e. the two carrying structures of a pair of silicon rod carrying structures are jointly rotated by means of a silicon rod rotation mechanism.

Referring to fig. 5, two silicon rod carrying structures are disposed on the supporting platform 21, each silicon rod carrying structure includes a pair of silicon rod carrying structures 23, at least one pair of silicon rod bearing structures 23 in the two groups of silicon rod bearing structures are respectively arranged at two opposite side ends of the bearing platform 21, namely, a first configuration area and a second configuration area are respectively arranged at two opposite sides of the supporting platform 21, a first group of silicon rod bearing structures are arranged on the first configuration area, the first group of silicon rod carrying arrangements comprises a pair of silicon rod carrying arrangements (which may also be referred to as first pair of silicon rod carrying arrangements) provided with a first silicon rod rotation mechanism, a second group of silicon rod carrying structures (this pair of silicon rod carrying structures may also be referred to as a second pair of silicon rod carrying structures) is provided on the second arrangement region, and the second pair of silicon rod carrying structures is provided with a second silicon rod rotating mechanism. The first silicon rod rotating mechanism can be used for driving two silicon rod bearing structures in the first pair of silicon rod bearing structures and the silicon rods borne by the silicon rod bearing structures to rotate by a preset angle, and the second silicon rod rotating mechanism can be used for driving two silicon rod bearing structures in the second pair of silicon rod bearing structures and the silicon rods borne by the silicon rod bearing structures to rotate by a preset angle.

Referring to fig. 8, which is a partially enlarged view of fig. 5, in combination with fig. 5 and 8, for any one of the silicon rod rotating mechanisms, the silicon rod rotating mechanism includes: a first rotating member 241, a second rotating member 242, a link member 243, and a transmission assembly 244.

The first rotating member is journaled to a rotating shaft of a first one of the pair of silicon rod carrying structures. In the embodiment shown in fig. 5, the first rotating member 241 comprises a first rotating body having a shaft portion journaled to the rotating shaft of the first one of the pair of silicon rod carrying structures and a movable joint.

The second rotating member is journaled to a rotating shaft of a second one of the pair of silicon rod carrying structures. In the embodiment shown in fig. 5, the first rotating member 241 comprises a second rotating body having a shaft portion in the middle and two movable joints (which may be referred to as a first movable joint and a second movable joint, respectively) at opposite ends, wherein the shaft portion is journaled to the rotating shaft of the second one of the pair of silicon rod carrying structures.

The connecting rod part is movably connected to the first rotating part and the second rotating part. In the embodiment shown in fig. 5, the link member 243 has a first connecting end and a second connecting end, wherein the first connecting end is movably connected to the movable joint of the first rotating member 241, and the second connecting end is movably connected to the first movable joint of the second rotating member 242. In a specific implementation manner, the movable joint of the first connecting end movably connected to the first rotating part may adopt a shaft connection manner, and the first movable joint of the second connecting end movably connected to the second rotating part may adopt a shaft connection manner.

The transmission assembly is associated with either the first rotating member or the second rotating member. In the embodiment shown in fig. 5, the transmission assembly 244 is an air cylinder, and the rod of the air cylinder is movably connected to the second rotating member 242, i.e. the rod of the air cylinder is movably connected to the second movable joint of the second rotating member 242. In a specific implementation manner, the cylinder rod of the cylinder is movably connected to the second movable joint of the second rotating part by adopting a shaft connection manner.

When the transmission component is controlled, the related first rotating part or the second rotating part is driven to drive the first silicon rod bearing structure or the second silicon rod bearing structure to rotate, and the second silicon rod bearing structure or the first silicon rod bearing structure is driven to rotate through the connecting rod part. In the embodiment shown in fig. 5, when the cylinder driving cylinder rod as the transmission component 244 extends, the cylinder rod drives the second rotating component 242 to rotate in the forward direction (taking fig. 5 as an example, the forward rotation corresponds to clockwise rotation when viewed from the bottom to the top of the supporting platform 21), at this time, the second silicon rod bearing structure 23 coupled with the second rotating component 242 also rotates in the forward direction, and accordingly, the first rotating component 241 rotates in the forward direction (taking fig. 5 as an example, the forward rotation corresponds to clockwise rotation when viewed from the bottom to the top of the supporting platform 21) under the action of the connecting rod component 243 through the transmission of the connecting rod component 243 under the driving of the second rotating component 242, at this time, the first silicon rod bearing structure 23 coupled with the first rotating component also rotates in the forward direction. The turning direction of the first silicon rod bearing structure 23 is consistent with the turning direction of the second silicon rod bearing structure 23, and the rotating angle of the first silicon rod bearing structure 23 in the forward rotation direction is consistent with the rotating angle of the second silicon rod bearing structure 23 in the forward rotation direction through the design of each part in the silicon rod rotating mechanism. For example, the first and second silicon rod carrying structures 23, 23 have a rotation angle of 90 °. Of course, the rotation angle may be varied in other ways, for example, 45 ° or 180 °.

Similarly, when the cylinder serving as the transmission assembly 244 retracts, the cylinder rod drives the second rotating member 242 to rotate in the reverse direction (for example, in fig. 5, the forward rotation corresponds to counterclockwise rotation when viewed from the bottom to the top of the supporting platform 21), and at this time, the second silicon rod bearing structure 23 coupled to the second rotating member also rotates in the reverse direction, and accordingly, the first rotating member 241 rotates in the reverse direction under the action of the connecting rod member 243 (for example, in fig. 5, the forward rotation corresponds to counterclockwise rotation when viewed from the bottom to the top of the supporting platform 21) through the transmission of the connecting rod member 243 under the driving of the second rotating member 242, and at this time, the first silicon rod bearing structure 23 coupled to the first rotating member also rotates in the reverse direction. The turning direction of the first silicon rod bearing structure 23 is the same as the turning direction of the second silicon rod bearing structure 23, and the rotating angle of the first silicon rod bearing structure 23 which rotates reversely can be the same as the rotating angle of the second silicon rod bearing structure 23 which rotates reversely by designing each part in the silicon rod rotating mechanism. For example, the first and second silicon rod carrying structures 23, 23 have a rotation angle of 90 °. Of course, the rotation angle may be varied in other ways, for example, 45 ° or 180 °.

Of course, in some embodiments, the direction of rotation of the first silicon rod carrying structure 23 may be opposite to the direction of rotation of the second silicon rod carrying structure 23, i.e., the first silicon rod carrying structure 23 rotates in a forward direction and the second silicon rod carrying structure 23 rotates in a reverse direction, but the rotation angle of the first silicon rod carrying structure 23 in the forward direction corresponds to the rotation angle of the second silicon rod carrying structure 23 in the reverse direction, for example, the rotation angle is 90 °; alternatively, the first silicon rod carrying structure 23 is rotated in the reverse direction and the second silicon rod carrying structure 23 is rotated in the forward direction, but the first silicon rod carrying structure 23 is rotated in the reverse direction by a rotation angle corresponding to the rotation angle of the second silicon rod carrying structure 23 in the forward direction, for example, the rotation angle is 90 °.

In the silicon rod bearing device of the present application, the silicon rod rotating mechanism may further include a limiting part adjacently disposed to the connecting rod part. In the embodiment shown in fig. 5, a limit member 245 is further disposed beside the link member 243, and the limit member 245 may be, for example, a limit stopper for limiting the movement of the link member 243. In practical applications, the position of the limit stopper 245 may be used to limit the movement of the connecting rod part 243 and ensure that the rotation angle of the first and second silicon rod carrying structures 23 and 23 when limiting the movement of the connecting rod part 243 corresponds to a predetermined angle.

Correspondingly, the second direction shifting mechanism comprises a second direction guide structure and a second driving device, the second direction guide structure is arranged on the base and used for arranging the reversing carrier, the reversing carrier is driven by the second driving device to move along the second direction guide structure, and the second direction guide structure comprises at least one second direction guide rod or at least one second direction guide rail.

The reversing carrier and the silicon rod clamp on the reversing carrier can be driven by the shifting mechanism to shift on the base along at least one direction, so that the silicon rod clamp moves to a first preset position to clamp a silicon rod to be cut or a cut silicon rod and transfers the clamped silicon rod to be cut or the cut silicon rod to a second preset position.

Here, the first predetermined position and the second predetermined position are limited to fixed positions or areas established in the established coordinate system, and in the example provided in the present application, by determining a transfer path of the handling device in handling, a start position in the silicon rod handling device in the transfer path is taken as the first predetermined position and an end position is taken as the second predetermined position in accordance with a time sequence of transfer.

The reversing carriage 41 can be moved in a reversing manner, for example, by means of a reversing mechanism.

In some embodiments, the reversing mechanism that enables the reversing vehicle 41 to effect the reversing motion may include: a rotating shaft and a rotating motor (not shown), the reversing carrier 41 is connected to a mounting base (the mounting base may be, for example, a base of a multi-wire cutting apparatus or a working platform of the multi-wire cutting apparatus) below the reversing carrier 41 through the rotating shaft, a connecting end of the rotating shaft for connecting with the reversing carrier 41 may be provided with an outward-extending mounting edge, mounting holes are uniformly distributed on the mounting edge, correspondingly, a mounting hole is also arranged at a central position of a base 411 in the reversing carrier 41, when the reversing carrier 41 is installed, the base 411 in the reversing carrier 41 is butted with the rotating shaft, the mounting hole on the base 411 is aligned with the mounting hole on the rotating shaft, and then, an attaching member such as a bolt penetrates through the aligned mounting hole and is then attached to complete the assembly of the reversing carrier 41. When the steering movement is performed, the rotating motor is started to drive the rotating shaft to rotate so as to drive the reversing carrier 41 to rotate to realize the reversing movement. The aforementioned rotation of the drive rotation shaft may be designed as a one-way rotation, which may be, for example, a clockwise rotation or a counterclockwise rotation, or as a two-way rotation, which may be, for example, a clockwise rotation and a counterclockwise rotation. The angle of rotation of the drive rotary shaft may be set according to the actual configuration of the silicon rod loading and unloading device (for example, according to the configuration of the direction-changing carrier 41, the installation positional relationship between the silicon rod holder 42 provided on the direction-changing carrier 41 and the loading station or the unloading station, and the like). Moreover, the base 411 of the reversing carrier 41 may be a disk structure, a square disk or an oval disk, and the central position of the base is connected with the rotating shaft, but the shape of the base 411 is not limited thereto, and in other embodiments, the base 411 may also be in other shapes.

In some embodiments, the reversing mechanism that enables the reversing vehicle 41 to effect the reversing motion may include: the reversing fluted disc is arranged on the reversing carrier; the rotating gear is meshed with the reversing fluted disc; and a driving source for driving the rotating gear to rotate. As shown in fig. 10 and 11, the reversing toothed disc 415 is disposed on the base 411 of the reversing carrier 41, and the rotating gear 416 (see also fig. 12) is engaged with the reversing toothed disc.

The addendum circle diameter of the reversing fluted disc 415 is larger than the addendum circle diameter of the rotating gear 416, the driving source 417 is arranged on one side of the rotating gear 416 and is fixedly connected with the rotating gear 416, the connection form between the driving source 417 and the rotating gear 416 includes key connection, tightening ring connection, tightening screw connection interference fit connection and the like, the rotating gear 416 is rotated by controlling the driving source 417, the reversing fluted disc 415 and a rotary bearing arranged on the inner side of the reversing fluted disc 415 are driven to rotate, and a silicon rod clamp arranged on a reversing mechanism performs reversing rotation, so that the transmission between two parallel shafts of the shaft of the reversing fluted disc 415 and the shaft of the reversing fluted disc 415 is realized. The driving source 417 may be, for example, a servo motor.

In the embodiment shown in fig. 10 and 11, the reversing toothed disc 415 may be disposed on an external gear on the outer periphery of the rotating shaft, the rotating gear 416 is engaged with the reversing toothed disc 415, and the driving power source 417 may be, for example, a servo motor, whose motor shaft is connected to the rotating gear 416. In other embodiments, the reversing toothed disc may be an internal gear disposed on an inner edge of the rotating shaft, the rotating gear is engaged with the reversing toothed disc, and the driving power source 417 may be a servo motor, and a motor shaft of the servo motor is connected to the rotating gear 416.

In some embodiments, the reversing gear and the reversing toothed disc include various types, such as a straight toothed spur gear, a helical toothed spur gear, a herringbone toothed gear, a curved toothed gear, a worm gear, and the like, and accordingly, according to different types of the reversing gears, the reversing gear shaft and the reversing toothed disc shaft may also be intersected at a given angle or in a spatial non-planar positional relationship, so that the positions of the reversing gear and the reversing toothed disc have different settings.

At least one silicon rod gripper 42 is arranged on the reversing carrier 41 for gripping a corresponding workpiece. In the present embodiment, it is assumed that the silicon rod clamp 42 is disposed in the silicon rod clamp region of the reversing carrier 41 and can be used for clamping silicon rods (including silicon rods to be cut having a circular cross section and cut silicon rods having a quasi-rectangular cross section). In this way, the reversing carrier 41 is driven by the reversing mechanism to perform reversing movement, so that the silicon rod clamp 42 on the reversing carrier 41 is switched among different positions to transfer the clamped silicon rod to be cut and/or the cut silicon rod. In practical applications, the rotation angle of the reversing carrier 41 for reversing motion is determined according to the position relationship among the loading station, the cutting station (which can be located in the loading and unloading area), and the unloading station.

For example: in one case, the feeding station, the squaring station, and the discharging station are sequentially arranged and distributed at 120 ° between each other, and assuming that the silicon rod clamp 42 on the reversing carrier 41 corresponds to the feeding station in the initial state, the silicon rod clamp can be switched from the feeding station to the squaring station by driving the reversing carrier 41 to rotate forward by 120 ° through the reversing mechanism, the silicon rod clamp 42 can be switched from the squaring station to the discharging station by driving the reversing carrier 41 to rotate forward by 120 °, and the silicon rod clamp 42 can be switched from the discharging station to the feeding station by driving the reversing carrier 41 to rotate forward by 120 ° or reversely by 240 °.

In another situation, the feeding station, the opening station and the discharging station are sequentially arranged, the difference between the feeding station and the opening station is 180 °, the discharging station is located between the feeding station and the opening station, the difference between the discharging station and the feeding station is 90 ° and the difference between the discharging station and the opening station is 90 °, assuming that the silicon rod clamp 42 on the reversing carrier 41 corresponds to the feeding station in the initial state, the silicon rod clamp 42 can be switched from the feeding station to the opening station by driving the reversing carrier 41 to rotate forward by 180 °, the silicon rod clamp 42 can be switched from the opening station to the discharging station by driving the reversing carrier 41 to rotate forward by 90 ° or reversely by 90 °, and the silicon rod clamp 42 can be switched from the discharging station to the discharging station by driving the reversing carrier 41 to rotate forward by 90 ° or reversely by 90 °.

In another case, the feeding station and the discharging station are located at the same position and may be called as a feeding and discharging station, and the feeding and discharging station and the squaring station are arranged opposite to each other with a difference of 180 °, and assuming that the silicon rod clamp 42 on the reversing carrier 41 corresponds to the feeding and discharging station in the initial state, the silicon rod clamp 42 may be switched from the feeding and discharging station to the squaring station by driving the reversing carrier 41 to rotate forward by 180 °, and the silicon rod clamp 42 may be switched from the squaring station to the blanking station by driving the reversing carrier 41 to rotate forward by 180 ° or reversely by 180 °.

In another case, the feeding station and the discharging station are located at the same position and can be called as a feeding and discharging station, and the feeding and discharging station and the squaring station can differ by 90 degrees, and assuming that the silicon rod clamp 42 on the reversing carrier 41 corresponds to the feeding and discharging station in the initial state, the silicon rod clamp 42 can be switched from the feeding and discharging station to the squaring station by driving the reversing carrier 41 to rotate forward by 90 degrees through the reversing mechanism, and the silicon rod clamp 42 can be switched from the squaring station to the blanking station by driving the reversing carrier 41 to rotate backward by 90 degrees.

In each of the above cases, the forward rotation specifically refers to a rotation direction in the order of the arrangement of the feeding station, the squaring operation station, and the discharging station, and a rotation opposite to the forward rotation is referred to as a reverse rotation. Specifically, if the feeding station, the squaring operation station and the blanking station are arranged in a clockwise sequence, the forward rotation is clockwise rotation, and the counterclockwise rotation is reverse rotation; if the feeding station, the squaring operation station and the blanking station are arranged according to the anticlockwise sequence, the forward rotation is anticlockwise rotation, and the clockwise rotation is reverse rotation. However, no matter how, the arrangement relationship of the feeding station, the squaring station, and the blanking station is not particularly limited, and the arrangement order and the arrangement angle therebetween may be changed, so long as no unnecessary interference is generated between the stations, and thus the rotation direction and the rotation angle of the silicon rod holder 42 on the reverse carrier 41 may be adjusted adaptively.

The silicon rod handling device further comprises a positioning mechanism matched with the reversing mechanism and used for positioning after the reversing carrier reverses and rotates for a preset angle.

Referring to fig. 13, which is a partial cross-sectional view of a positioning mechanism in a silicon rod loading and unloading device according to an embodiment of the present disclosure, as shown in the figure, the silicon rod loading and unloading device for a multi-station squaring apparatus further includes a positioning mechanism cooperating with the reversing mechanism for positioning after the reversing carrier reverses and rotates a predetermined angle, and in a working state, a control command for rotating the predetermined angle is sent by a control program and received by the driving source or the driving motor, so as to drive the rotating gear and the meshed reversing toothed disc 415 to rotate. The predetermined angle may be achieved by the number of meshing teeth traveled by the rotary gear and the rotary toothed disc, and in some cases, the angle of rotation of the rotary gear and the rotary toothed disc may deviate from the predetermined angle of the reversing rotation of the reversing carrier due to loss of steps of the motor, gear machining errors, and the like, and the deviation may increase as the predetermined angle increases.

In some embodiments, the predetermined angle of the reversing carrier for reversing rotation may be set to a certain value, at which the silicon rod clamp can smoothly achieve loading and unloading of the silicon rod to be cut or the cut silicon rod from the first predetermined position to the second predetermined position or from the second predetermined position to the first predetermined position, the positioning mechanism is disposed at a designated position on the mounting seat, and after the driving source or the driving motor completes the control instruction, the positioning mechanism compensates for the rotation angle of the rotating toothed disc, so that the rotation angle of the silicon rod clamp between the first predetermined position and the second predetermined position can be accurately positioned.

As shown in fig. 12, the positioning mechanism may include a positioning groove 418 and a positioning pin 419 that is engaged with the positioning groove 418, the positioning groove 418 is a groove-shaped structure that is inserted into the mounting seat and partially disposed on the reversing fluted disc 415, the positioning pin 419 is fixedly connected to the mounting seat, the positioning pin 419 is a cylinder structure with a telescopic rod, the telescopic rod is capable of extending and retracting along an axial direction of the telescopic rod, during rotation of the reversing fluted disc 419, the telescopic rod of the positioning pin 419 is located below the positioning groove 418, and after rotation of the reversing fluted disc 419 is completed, the positioning pin 419 is driven by a driving mechanism to lift the telescopic rod of the positioning pin 419 and extend into the positioning groove 418 to complete precise positioning.

In a specific application, the positioning slot 418 may be, for example, a ball socket, and the positioning pin 419 may be, for example, a ball tip engaged with the ball socket. Furthermore, a zenith opening can be additionally arranged at the top of the ball socket, and correspondingly, a tip matched with the zenith opening can be arranged at the top of the ball tip, so that accurate positioning can be realized.

In some embodiments, for the positioning structure, the ball tip as the positioning pin 419 may further be configured with an elastic member, such as a spring, and the like, and in a non-pressed state, the ball tip may be upwardly protruded by the elastic member, and in a pressed state, the ball tip may be pressed to be contracted. Therefore, when the reversing fluted disc 419 is driven by the rotation driving unit to rotate, the ball pin is pressed to be in a contracted state until the ball socket of the reversing fluted disc 419 is rotated, and when no obstacle exists above the ball pin and the ball pin is in a non-pressure state, the ball pin can be protruded upwards under the action of the elastic component and enter the ball socket, so that the positioning is realized.

In some embodiments, for the locating feature, the locating slot and the locating pin are configured to be magnetic. Taking the positioning groove as a ball socket and the positioning pin as a ball pin as an example, one of the ball socket and the ball pin may be provided with a magnetic material and the other may be a metal that can be magnetically attracted, or the ball socket and the ball pin may be provided with opposite magnetic materials, although in such an embodiment, the ball pin may also be provided with a telescopic design. In this way, when the reversing fluted disc 419 is driven by the rotation driving unit to rotate, and the ball socket approaches the ball tip, the ball tip is attracted to extend out of the ball socket and penetrate into the ball socket due to opposite attraction, so that positioning is realized.

As before, this application silicon rod handling device is applied to in the multistation evolution equipment, the wire cutting device among the multistation evolution equipment treats cutting silicon rod and cuts the evolution operation, so, can be with the section be circular treat that cutting silicon rod forms into the cut silicon rod that the section is the quasi-rectangle after cutting the evolution operation. Therefore, the silicon rod clamp in the silicon rod loading and unloading device can clamp both the silicon rod to be cut and the cut silicon rod.

The silicon rod holder 42 will be described in detail below.

The silicon rod clamp 42 comprises a silicon rod clamp mount 421 at least two link clamps 422, wherein the at least two link clamps 422 are spaced apart with respect to the silicon rod clamp mount 421. In one embodiment, the silicon rods to be clamped (including the silicon rods to be cut and the cut silicon rods) are placed vertically, and thus, the at least two link clamps 422 are spaced apart from each other in the third direction with respect to the silicon rod clamp mounting member 421, i.e., the at least two link clamps 422 are disposed up and down.

In a specific implementation manner, any one of the link-type clamping members 422 further includes: the silicon rod clamp comprises a clamping arm mounting seat 4221 and at least two clamping arms 4222, wherein the clamping arm mounting seat 4221 is arranged on the silicon rod clamp mounting piece 421, and the at least two clamping arms 4222 are movably arranged on the clamping arm mounting seat 4221. In an alternative embodiment, two clamping arms 4222 constituting the link-type clamping member 422 are provided, the two clamping arms 4222 are arranged symmetrically left and right, the two clamping arms 4222 can also be respectively referred to as a first clamping arm and a second clamping arm, and a single clamping arm 4222 is provided with two clamping teeth arranged in a front-back manner, so that the clamping teeth (four in total) on the two clamping arms 4222 can form a clamping space for clamping the silicon rod. Additionally, the link-type clamp 422 can also be used for centering adjustment. In general, when the clamping arms 4222 in the link-type clamping member 422 are in a clamped state, the center of the clamping space formed by the two clamping arms 4222 coincides with the center of the silicon rod. Therefore, when the rod-type clamping member 422 is used to clamp a vertically placed silicon rod, the two clamping arms 4222 in the rod-type clamping member 422 contract and are abutted against the silicon rod by the clamping teeth in the clamping arms 4222. During the process of contracting and clamping the silicon rod by the clamping arms 4222, the silicon rod is pushed by the two clamping arms 4222 at both sides and moves towards the central area of the clamping space until the silicon rod is clamped by the two clamping arms 4222 in the link-type clamping part 422, and at the moment, the center of the silicon rod can be positioned at the center of the clamping space of the link-type clamping part 422. Certainly, a buffer part can be additionally arranged on the clamping teeth in the clamping arm 4222 to avoid damage to the surface of the silicon rod in the process of clamping the silicon rod, so that a good effect of protecting the silicon rod is achieved.

In order to enable at least two clamping arms 4222 in the connecting rod type clamping member 422 to smoothly and stably clamp silicon rods with different dimensions, the connecting rod type clamping member 422 further comprises a clamping arm driving mechanism for driving the at least two clamping arms 4222 to open and close.

Take the example where the link-type clamp 422 includes two clamp arms. The clamp arm driving mechanism may further include: the clamping device comprises a connecting rod assembly and a driving source, wherein the connecting rod assembly is used for connecting a first clamping arm and a second clamping arm, and the driving source is used for driving the first clamping arm and the second clamping arm to perform opening action or closing action.

As shown in fig. 10 and 11, in the present embodiment, the first and second clamp arms 4222 and 4222 are oppositely disposed on the clamp arm mount 4221 through a guide structure. The guide structure may be, for example, an opening and closing guide rod 4223, that is, opening and closing guide rods 4223 are disposed on opposite sides of the clamp arm mounting seat 4221, the opening and closing guide rod 4223 may be disposed horizontally, mounting holes are disposed on the first clamp arm 4222 and the second clamp arm 4222, and the first clamp arm 4222 and the second clamp arm 4222 are mounted on the clamp arm mounting seat 4221 after the opening and closing guide rod is inserted into the mounting holes of the first clamp arm 4222 and the second clamp arm 4222. The number of the opening and closing guide rods 4223 is not limited, and may be designed according to the structures of the first and second clamp arms 4222 and the states of the first and second clamp arms 4222 and 4222 performing opening or closing motions. For example, in some embodiments, the number of the opening and closing guide rods 4223 is two, the two opening and closing guide rods 4223 are arranged in parallel, for example, in an up-down parallel arrangement or a horizontal parallel arrangement, the first arm clamp 4222 and the second arm clamp 4222 are mounted to the arm clamp mounting seat 4221 through the two opening and closing guide rods 4223, and compared with a single opening and closing guide rod design, the two opening and closing guide rods 4223 not only ensure the stability of the first arm clamp 4222 and the second arm clamp 4222 mounted to the arm clamp mounting seat 4221, but also ensure the smoothness of the opening and closing actions of the first arm clamp 4222 and the second arm clamp 4222, and further avoid the problem that the first arm clamp 4222 and the second arm clamp 4222 are easily turned around the single opening and closing guide rod in the single opening and closing guide rod design. In some embodiments, the number of the opening and closing guide rods 4223 is three or more, and in the case that the number of the opening and closing guide rods 4223 is three, the three opening and closing guide rods 4223 are arranged in parallel and in a triangular manner.

Returning to the clamping arm driving mechanism, a connecting rod assembly in the clamping arm driving mechanism is used for associating the first clamping arm with the second clamping arm. Fig. 14 is a schematic structural view of a clamping arm driving mechanism in the silicon rod loading and unloading device according to an embodiment of the present invention. As shown, the connecting rod assembly may further include: the clamp arm mounting structure comprises a first connecting rod 4231, a second connecting rod 4232 and an adapter plate 4233, wherein the adapter plate 4233 is connected to a clamp arm mounting seat 4221 in a shaft mode, two opposite ends of the adapter plate 4233 are respectively provided with a first movable joint and a second movable joint, the first movable joint of the adapter plate 4233 is movably connected to a first end of the first connecting rod 4231, the second movable joint of the adapter plate 4233 is movably connected to a first end of the second connecting rod 4232 in a shaft mode, a second end of the first connecting rod 4231 is connected to the first clamp arm 4222 in a shaft mode, and a second end of the second connecting rod 4232 is connected to the second clamp arm 4222 in a shaft mode. In a specific implementation manner, the first movable joint of the adapter plate 4233 is movably connected to the first end of the first link 4231 in a shaft coupling manner, and the second movable joint of the adapter plate 4233 is movably connected to the first end of the second link 4232 in a shaft coupling manner.

And a driving source in the clamping arm driving mechanism is connected to the first clamping arm or the second clamping arm and is used for driving the connected clamping arm and driving the other clamping arm through the connecting rod component, so that the first clamping arm and the second clamping arm move along the guide structure to perform opening or closing actions. In the embodiment shown in fig. 14, the driving source 4234 is connected to the first clamping arm 4222, and is configured to drive the connected first clamping arm 4222 and drive the second clamping arm 4222 via the link assembly, so that the first clamping arm 4222 and the second clamping arm 4222 move along the opening and closing guide rod 4223 to perform an opening motion or a closing motion. For example, the driving source 4234 is a cylinder, and a cylinder shaft of the cylinder is connected to the first clamp arm 4222. In practical applications, when the cylinder 4234 drives the cylinder shaft to extend, the first clamping arm 4222 is controlled by the cylinder shaft to move towards the central region along the opening and closing guide rod 4223, and at this time, the first link 4231 in the link assembly also moves towards the central region and drives the adapter 4233 to turn over (counterclockwise as shown in fig. 14), and under the driving of the adapter 4233, the second link 4232 moves towards the central region and drives the second clamping arm 4222 to move towards the central region along the opening and closing guide rod 4223, so that the first clamping arm 4222 and the second clamping arm 4222 move towards each other to contract the clamping space, so as to clamp the silicon rod located in the central region. When the cylinder 4234 drives the cylinder shaft to contract, the first clamp arm 4222 is controlled by the cylinder shaft to move outwards along the opening and closing guide rod 4223, at this time, the first link 4231 in the link assembly also moves outwards and drives the adapter plate 4233 to turn over (clockwise as shown in fig. 14), and under the driving of the adapter plate 4233, the second link 4232 moves outwards and drives the second clamp arm 4222 to move outwards along the opening and closing guide rod 4223, so that the first clamp arm 4222 and the second clamp arm 4222 move back and forth, the clamping space is expanded, and the silicon rod which is originally clamped can be released. Referring to fig. 15 and 16, fig. 15 is a schematic view showing a silicon rod clamp in the silicon rod loading and unloading device of the present application clamping a silicon rod to be cut, and fig. 16 is a schematic view showing a silicon rod clamp in the silicon rod loading and unloading device of the present application clamping a cut silicon rod. In fig. 15, a silicon rod 100 to be cut having a circular cross section can be held by the silicon rod holder 42, and in fig. 16, a cut silicon rod 101 having a rectangular-like cross section can be held by the silicon rod holder 42.

In order to reduce or even eliminate the risk that the rod-shaped holding members 422 may not be able to hold the silicon rod, the silicon rod holder 42 may have different designs.

In some embodiments, the silicon rod clamp employs a fixed silicon rod holder, that is, as many silicon rod holders as possible are vertically and fixedly disposed on the reversing carrier, and the distance between two adjacent silicon rod holders in the silicon rod holders is as small as possible, so that silicon rods with various specifications and lengths can be covered by the link-type holders 422. For example, if the length of the silicon rod is longer, more silicon rod clamping parts on the reversing carrier are used for clamping; if the length of the silicon rod is shorter, fewer silicon rod holders on the reversing carrier are used for holding, for example, several silicon rod holders located below are used for holding, while those located above and above the silicon rod are not used.

In some embodiments, the silicon rod clamp 42 is a liftable silicon rod holder, i.e. a silicon rod holder is movably arranged on the mounting surface of the reversing carrier in a vertical manner, and the number of silicon rod holders can be greatly reduced due to the movable design of the silicon rod holder, and generally two or three silicon rod holders can be satisfied. Therefore, the silicon rods with various specifications and lengths can be covered by the movable clamping piece. For example, if the length of the silicon rod is long, the movably arranged silicon rod clamping members are lifted, and the clamping distance between the two silicon rod clamping members is prolonged; if the length of the silicon rod is short, the movably arranged connecting rod type clamping piece 422 is lowered, and the clamping distance between the two connecting rod type clamping pieces 422 is shortened.

In the implementation mode that silicon rod clamp 42 adopts the silicon rod holder of liftable formula, for the smooth and steady up-and-down activity of silicon rod holder of liftable formula is in order to adjust the position, in this application silicon rod loading attachment, silicon rod clamp still includes lift actuating mechanism for at least one connecting rod formula holder edge in two at least connecting rod formula holders of drive reversing carrier makes elevating movement.

Fig. 17 is a schematic structural view of a lift driving mechanism in a silicon rod loading and unloading device according to an embodiment of the present disclosure. As shown, the silicon rod clamp 42 further comprises a lifting driving mechanism for driving at least one link-type clamping member 422 of the at least two link-type clamping members 422 to perform a lifting movement along the silicon rod clamp mounting member 421. For example, when the silicon rod clamp 42 includes two link-type clamping members, one of the link-type clamping members 422 may be fixed on the silicon rod clamp mounting member 421, and the other link-type clamping member 422 is movably disposed on the silicon rod clamp mounting member 421 and driven by the lifting driving mechanism to move up and down along the axis of the vertically disposed silicon rod; for another example, the two link type clamping members 422 of the silicon rod clamp 42 may be movably disposed on the silicon rod clamp mounting member 421, and driven by the lifting driving mechanism to move up and down along the axis of the vertically disposed silicon rod. The lifting driving mechanism can reduce or even avoid the risk that the connecting rod type clamping piece can not clamp the silicon rod.

In certain embodiments, the lift drive mechanism comprises: the lifting guide rod is used for arranging the clamping arm mounting seat; the transmission chain is wound on two transmission chain wheels which are arranged up and down, wherein at least one transmission chain wheel in the two transmission chain wheels is in shaft connection with a chain wheel driving source; and the locking device is arranged on the at least one connecting rod type clamping piece and used for converting two states of locking and moving between the at least one connecting rod type clamping piece and the transmission chain.

The at least one locking device corresponds to the at least one link-type clamping element, for example, when the locking device is one, i.e., is disposed on one link-type clamping element, and when the locking device is two, the locking device is disposed on two link-type clamping elements, each locking device is used for controlling a locking or moving state between one link-type clamping element and the transmission chain, so as to realize state switching of the link-type clamping element moving along with the transmission chain or stopping at a preset height on the silicon rod clamp.

The elevation driving mechanism includes an elevation guide rod 4241 disposed in a vertical direction (i.e., the third direction), and further, as shown in the drawing, in some embodiments, the elevation guide rod 4241 may be the same as the silicon rod clamp mounting member 421, and in other embodiments, the elevation guide rod 4241 may be a different member from the silicon rod clamp mounting member 421. The arm lock mounting seats 4221 of the at least two link type clamping members 422 are disposed on the lifting guide rod 4241, so that the link type clamping members 422 can move up and down along the lifting guide rod 4241, the lifting driving mechanism is provided with a transmission chain 4242, the transmission chain 4242 can be configured as an annular chain and wound around two transmission chain wheels 4243 which are disposed up and down, at least one of the wound transmission chain wheels 4243 is driven to rotate by a chain wheel driving source 4244 such as a driving motor, thereby driving the transmission chain 4242 engaged with the transmission chain wheel 4243 to move, and the direction of movement of the transmission chain 4242 is determined by the positions of the transmission chain wheels 4243 which are disposed up and down, for example, when the transmission chain wheels 4243 which are disposed up and down are located on the same plumb line, the transmission chain 4242 between the two transmission chain wheels 4243 moves in the lifting direction.

In addition, the lifting driving mechanism also comprises at least one locking device. In some embodiments, the locking device comprises: the silicon rod clamping device comprises a locking chain wheel 4245 and at least one locking mechanism, the locking chain wheel 4245 is rotatably arranged on the silicon rod clamping piece and meshed with the transmission chain 4242, and the locking mechanism is arranged on the silicon rod clamping piece and used for locking the locking chain wheel 4245 to enable the locking chain wheel 4245 to be static relative to the transmission chain 4242, so that the silicon rod clamping piece connected with the locking chain wheel 4245 is switched to a locking state from an active state. Here, the locking sprocket 4245 may be connected to the silicon rod holder via a sprocket rotation shaft, and in a rest state of the locking mechanism, the locking sprocket 4245 is rotated about the sprocket rotation shaft by the engaged drive chain 4242; when the locking mechanism is in an operating state, the locking mechanism limits the rotation of the locking sprocket 4245 so as to provide a force to the locking sprocket 4245 and the silicon rod clamping member to move in the lifting direction by the movement of the transmission chain 4242 in the lifting direction, and therefore, the silicon rod clamping member can be driven by the transmission chain 4242 to move up and down along the lifting guide rod in a state that the locking sprocket 4245 is stationary relative to the movement of the transmission chain 4242. Here, the lock mechanism may restrict rotation of the lock sprocket 4245 by, for example, gripping the teeth of the lock sprocket 4245.

In some embodiments, as shown in fig. 17, the locking mechanism comprises a locking cylinder 4246 and a locking portion 4247, wherein the locking portion 4247 is connected to a telescopic end of the locking cylinder 4246, and enters the gear teeth of the locking sprocket 4245 under the driving of the locking cylinder 4246 to lock the locking sprocket 4245.

At this time, the silicon rod clamping piece connected with the locking mechanism synchronously moves up and down along with the transmission chain 4242. When the silicon rod clamping member is lifted to a preset height, the locking portion 4247 retracts to enable the locking sprocket 4245 to restore to a state of being rotatably engaged with the transmission chain 4242 (in a state shown in fig. 18 a), and the silicon rod clamping member loses the force in the lifting direction transmitted by the locking sprocket 4245, so that the silicon rod clamping member can be stabilized at the preset height.

Here, switching between a locking state in which the silicon rod holder moves synchronously in compliance with the transmission chain 4242 or a relative movement state between the silicon rod holder and the transmission chain 4242 may be achieved based on the locking device, in an actual scene, the silicon rod holder and the transmission chain 4242 may be locked by the locking device based on a preset height adjustment of the silicon rod holder, and when the silicon rod holder is driven by the transmission chain 4242 to be lifted to the preset height, the locking device recovers the movement state between the silicon rod holder and the transmission chain 4242, so that the silicon rod holder may be stabilized at the preset height position of the lifting drive mechanism.

When the distance adjusting mechanism is used for driving the first wire cutting unit and the second wire cutting unit in the wire cutting device to move oppositely, the distance between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit can be reduced, and the distance adjusting mechanism can be suitable for cutting and squaring small silicon rods or increasing the cutting amount of the silicon rods; when the first wire cutting unit and the second wire cutting unit in the wire cutting device are driven by the distance adjusting mechanism to move back and forth, the distance between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit can be increased, and the device can be suitable for cutting and squaring silicon rods with larger sizes or reducing the cutting amount of the silicon rods. When the first wire cutting unit and the second wire cutting unit are driven to move along the second direction by the distance adjusting mechanism, the transition wheel in the first wire cutting unit and the cutting wheel are kept relatively static, and the transition wheel in the second wire cutting unit and the cutting wheel are kept relatively static.

In some embodiments, for each linear cutting unit, the cutting wheel in the linear cutting unit has at least two cutting line grooves, different cutting line grooves are parallel to each other, and the projection of the cutting line groove plane on the horizontal plane is along the first direction, and the different cutting line grooves have a cutting offset in the second direction. The transition wheel is provided with at least two wire grooves, different wire grooves are parallel to each other, transition offset is provided among different wire grooves, for example, at least part of the transition wheel is arranged in parallel with the cutting wheel, different wire grooves are parallel to each other, the projection of the wire groove plane on the horizontal plane is along the first direction, transition offset in the second direction is provided among different wire grooves, the number of the wire grooves in the transition wheel is consistent with the number of the cutting wire grooves in the cutting wheel, and each wire groove in the transition wheel corresponds to each cutting wire groove in the cutting wheel one by one, namely, the transition offset of each wire groove in the transition wheel is the same as the cutting offset of each cutting wire groove in the cutting wheel. Taking the wire cutting device shown in fig. 19 and 20 as an example, the wire cutting device includes a first wire cutting unit 32 and a second wire cutting unit 32, wherein the first wire is wound around the cutting wire groove of the first cutting wheel and the wire groove of the first transition wheel in the first wire cutting unit to form a multi-stage first cutting wire saw, and the second wire is wound around the cutting wire groove of the second cutting wheel and the wire groove of the second transition wheel in the second wire cutting unit to form a multi-stage second cutting wire saw. Therefore, the distance adjusting mechanism can be used for adjusting the cutting position of the cutting wire saw in the cutting line so as to control the cutting amount of the silicon rod, and groove changing operation of the cutting line can also be realized.

Taking the adjustment of the cutting position of the cutting wire saw as an example, when the first wire cutting unit and the second wire cutting unit in the wire cutting device are driven by the distance adjusting mechanism to move oppositely, the distance between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit can be reduced, and the device can be suitable for cutting and squaring silicon rods with smaller sizes or increasing the cutting amount of the silicon rods; when the first wire cutting unit and the second wire cutting unit in the wire cutting device are driven by the distance adjusting mechanism to move back and forth, the distance between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit can be increased, and the device can be suitable for cutting and squaring silicon rods with larger sizes or reducing the cutting amount of the silicon rods. When the first wire cutting unit and the second wire cutting unit are driven to move along the second direction by the distance adjusting mechanism, the transition wheel in the first wire cutting unit and the cutting wheel are kept relatively static, and the transition wheel in the second wire cutting unit and the cutting wheel are kept relatively static.

It should be noted that, the direction in which the plurality of cutting wheels 321 in the wire cutting unit are moved by the distance adjusting mechanism 33 in the second direction is the direction in which the cutting wire groove a2 points to the cutting wire groove a1, and the cutting position of the cutting wire saw in space is unchanged 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 321 or other components, and the groove changing process is simplified. Taking the wire cutting device including the first wire cutting unit 32 and the second wire cutting unit 32 as an example, when the first wire cutting unit 32 and the second wire cutting unit 32 are driven by the distance adjusting mechanism to move in opposite directions along the second direction, the first cutting wire can be switched from the cutting wire groove on the inner side opposite to each first cutting wheel 321 originally wound in the first wire cutting unit 32 to the cylinder wire groove on the outer side opposite to each other, and the second cutting wire can be switched from the cutting wire groove on the inner side opposite to each cutting wheel 321 originally wound in the second wire cutting unit 32 to the cylinder wire groove on the outer side opposite to each other. When the first wire cutting unit 32 and the second wire cutting unit 32 are driven by the distance adjusting mechanism to move back and forth along the second direction, the first cutting line can be switched from the cutting line slot wound around the opposite outer side of each first cutting wheel 321 in the first wire cutting unit 32 to the cylinder line slot on the opposite inner side, and the second cutting line can be switched from the cutting line slot wound around the opposite outer side of each cutting wheel 321 in the second wire cutting unit 32 to the cylinder line slot on the opposite inner side. In such an adjustment using the pitch adjustment mechanism, in some cases, the transition wheel in the first wire cutting unit remains relatively stationary with the cutting wheel and the transition wheel in the second wire cutting unit remains relatively stationary with the cutting wheel. In some cases, the spacing between the first cutting wire saw in the first wire cutting unit 32 and the second cutting wire saw in the second wire cutting unit 32 may be maintained or adjusted, for example, by increasing the spacing between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit or by decreasing the spacing between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit.

In some embodiments, for each linear cutting unit, the cutting wheel in the linear cutting unit has at least two cutting line grooves, different cutting line grooves are parallel to each other, and the projection of the cutting line groove plane on the horizontal plane is along the first direction, and the different cutting line grooves have a cutting offset in the second direction. The transition wheel is provided with a wire groove, and one wire groove in the transition wheel corresponds to one cutting wire groove in the cutting wheel. The at least one wire cutting unit further comprises at least one shifting mechanism for driving the at least one transition wheel to move along the second direction, so that the wire groove wound by the cutting wire in the at least one transition wheel moves from the first cutting wire groove corresponding to the plurality of cutting wheels to the second cutting wire groove corresponding to the plurality of cutting wheels in the second direction. Taking the wire cutting device shown in fig. 19 and 20 as an example, the wire cutting device includes a first wire cutting unit 32 and a second wire cutting unit 32, wherein the first wire is wound around the cutting wire groove of the first cutting wheel and the wire groove of the first transition wheel in the first wire cutting unit to form a multi-stage first cutting wire saw, and the second wire is wound around the cutting wire groove of the second cutting wheel and the wire groove of the second transition wheel in the second wire cutting unit to form a multi-stage second cutting wire saw. Therefore, the distance adjusting mechanism and the shifting mechanism can be used for adjusting the cutting position of the cutting wire saw in the cutting line so as to control the cutting amount of the silicon rod, and can also be used for realizing the groove replacement operation of the cutting line.

Taking the adjustment of the cutting position of the cutting wire saw as an example, when the first wire cutting unit and the second wire cutting unit in the wire cutting device are driven by the distance adjusting mechanism to move oppositely, the distance between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit can be reduced, and the device can be suitable for cutting and squaring silicon rods with smaller sizes or increasing the cutting amount of the silicon rods; when the first wire cutting unit and the second wire cutting unit in the wire cutting device are driven by the distance adjusting mechanism to move back and forth, the distance between the first cutting wire saw in the first wire cutting unit and the second cutting wire saw in the second wire cutting unit can be increased, and the device can be suitable for cutting and squaring silicon rods with larger sizes or reducing the cutting amount of the silicon rods. When the first wire cutting unit and the second wire cutting unit are driven to move along the second direction by the distance adjusting mechanism, the transition wheel in the first wire cutting unit and the cutting wheel are kept relatively static, and the transition wheel in the second wire cutting unit and the cutting wheel are kept relatively static.

It should be noted that, the direction in which the plurality of cutting wheels 321 in the wire cutting unit are moved by the distance adjusting mechanism 33 in the second direction is the direction in which the cutting wire groove a2 points to the cutting wire groove a1, and the cutting position of the cutting wire saw in space is unchanged 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 321 or other components, and the groove changing process is simplified. However, in this case, in order to make the wire groove in the transition wheel correspond to the adjusted cutting wire groove a2, the transition wheel is driven by the shifting mechanism to move along the second direction to offset the moving distance of each cutting wheel in the second direction, that is, the moving mechanism drives the transition wheel to move along the second direction in the direction opposite to the moving direction of the cutting wheel driven by the distance adjusting mechanism in the second direction, and the moving distances of the transition wheel and the cutting wheel are the same.

Taking the case where the wire cutting apparatus includes the first wire cutting unit 32 and the second wire cutting unit 32, when the first wire cutting unit 32 and the second wire cutting unit 32 are driven to move toward each other by a predetermined distance in the second direction by the pitch adjusting mechanism, the first cutting line can be switched from the cutting line groove which is originally wound at the opposite inner side of each first cutting wheel 321 in the first line cutting unit 32 to the cylinder line groove at the opposite outer side, the second cutting line can be switched from the cutting line groove which is originally wound on the opposite inner side of each cutting wheel 321 in the second line cutting unit 32 to the cylinder line groove on the opposite outer side, and at this time, in order to ensure that the wire grooves in the transition wheels correspond to the adjusted cutting wire grooves, the shifting mechanism is used for driving each first transition wheel in the first wire cutting unit 32 to move outwards along the second direction by a preset distance, and the shifting mechanism is used for driving each second transition wheel in the second wire cutting unit 32 to move outwards along the second direction by a preset distance. When the first wire cutting unit 32 and the second wire cutting unit 32 are driven by the distance adjusting mechanism to move back and forth along the second direction, the first cutting line can be switched from the cutting line slot wound around the opposite outer side of each first cutting wheel 321 in the first wire cutting unit 32 to the cylinder line slot on the opposite inner side, the second cutting line can be switched from the cutting line slot wound around the opposite outer side of each cutting wheel 321 in the second wire cutting unit 32 to the cylinder line slot on the opposite inner side, at this time, in order to ensure that the wire guide slots in the transition wheels can correspond to the adjusted cutting line slots, each first transition wheel in the first wire cutting unit 32 is driven by the shifting mechanism to move inwards along the second direction for a predetermined distance, and each second transition wheel in the second wire cutting unit 32 is driven by the shifting mechanism to move inwards along the second direction for a predetermined distance.

Therefore, the at least one wire cutting unit further comprises at least one shifting mechanism for driving the at least one transition wheel to move along the second direction, so that the wire groove wound by the cutting wire in the at least one transition wheel moves from the first cutting wire groove corresponding to the plurality of cutting wheels to the second cutting wire groove corresponding to the plurality of cutting wheels in the second direction. Taking the wire cutting device shown in fig. 19 and 20 as an example, the wire cutting device includes a first wire cutting unit 32 and a second wire cutting unit 32, wherein the first wire is wound around the cutting wire groove of the first cutting wheel and the wire groove of the first transition wheel in the first wire cutting unit to form a multi-stage first cutting wire saw, and the second wire is wound around the cutting wire groove of the second cutting wheel and the wire groove of the second transition wheel in the second wire cutting unit to form a multi-stage second cutting wire saw.
