In the related art for processing a silicon rod, several steps such as cutting, grinding, chamfering, and the like are involved.
In general, most of conventional silicon rods have a cylindrical structure, and are cut by a silicon rod cutting device so that the silicon rods have a quasi-rectangular (including a quasi-square) cross section after cutting, and the processed silicon rods have a quasi-rectangular (including a quasi-cubic) shape as a whole.
Taking a single crystal silicon rod as an example, a process for forming the single crystal silicon rod may include: firstly, a silicon rod cutting machine is used for cutting the original long silicon rod to form a plurality of sections of short silicon rods; and after the cutting is finished, cutting the cut short silicon rod by using a silicon rod cutting machine to form the silicon single crystal rod with the rectangular-like cross section. Among them, patent publications such as CN105856445A, CN105946127A, and CN105196433A are referred to as a specific embodiment of forming a multi-stage short silicon rod by cutting an original long silicon rod with a silicon rod cutting machine, and patent publication such as CN105818285A is referred to as a specific embodiment of forming a single crystal silicon rod having a rectangular-like cross section by cutting a cut short silicon rod with a silicon rod cutting machine. However, the process for forming the single crystal silicon rod is not limited to the foregoing technique, and in alternative examples, the process for forming the single crystal silicon rod may further include: firstly, using a full silicon rod squaring machine to perform squaring operation on an original long silicon rod to form a long monocrystalline silicon rod with a quasi-rectangular cross section; and after the cutting is finished, cutting off the cut long monocrystalline silicon rod by using a silicon rod cutting machine to form a short crystalline silicon rod. Among them, a specific embodiment of the above-described method for forming a long single crystal silicon rod having a substantially rectangular shape by squaring an initial long silicon rod using an all-silicon-rod squarer is disclosed in patent publication CN106003443A, for example.
After the cylindrical silicon single crystal rod is cut into the quasi-rectangular silicon rod by the squaring equipment, the quasi-rectangular silicon rod can be ground, chamfered and the like by the grinding equipment.
The inventors of the present application have found that in the related art of the processing operation for the silicon rod, the processing devices such as the squaring and the polishing (for example, the surface polishing and the chamfering) are disposed separately and independently from each other, and the conversion of the silicon rod to perform different process operations requires the transfer and preparation and the pretreatment before the processing, which causes problems such as complicated processes and low efficiency.
In view of this, the application provides a silicon rod cutting and grinding all-in-one machine, through equipment transformation, a plurality of processingequipment have been assembled in an equipment, can realize the evolution cutting and the grinding (for example mill face, chamfer etc.) of silicon rod voluntarily, and seamless linking between each processing operation saves the cost of labor and improves production efficiency, improves the quality of silicon rod processing operation.
Referring to fig. 1 to 2, fig. 1 is a schematic view illustrating a three-dimensional structure of a silicon rod slicing and grinding machine according to an embodiment of the present disclosure, and fig. 2 is a top view of the silicon rod slicing and grinding machine according to the present disclosure.
In the embodiment, the silicon rod cutting and grinding all-in-one machine is used for performing processing operations such as cutting and grinding on a silicon rod, and the silicon rod is a single crystal silicon rod, but the silicon rod is not limited thereto, and for example, a polycrystalline silicon rod shall also belong to the scope of protection of the present application.
As shown, the silicon rod squaring apparatus disclosed herein comprises: a machine base 1, a cutting device 2, a grinding device 3 and a silicon rod conversion device 4. The base 1 has a silicon rod processing platform. The cutting device 2 is arranged on the base 1 and used for cutting the silicon rod on the first processing position of the silicon rod processing platform in the first direction and cutting the silicon rod on the second processing position of the silicon rod processing platform in the second direction to form a square silicon rod. The grinding device 3 is arranged on the base 1 and used for grinding and chamfering the square silicon rod on the third processing position of the silicon rod processing platform.
The machine base 1 serves as a main body part of the silicon rod multi-station processing machine and is provided with a silicon rod processing platform, wherein the silicon rod processing platform can be divided into a plurality of functional areas according to specific operation contents of silicon rod processing operation. Specifically, in the embodiment shown in fig. 1 and 2, the silicon rod processing platform comprises at least a waiting zone, a first processing zone, a second processing zone, and a third processing zone.
The silicon rod conversion device 4 is arranged in the central area of the silicon rod processing platform and used for converting the silicon rod 100 among a waiting area, a first processing area, a second processing area and a third processing area on the silicon rod processing platform. In an embodiment, the silicon rod transfer device 4 is rotatably disposed on the silicon rod processing platform, and the silicon rod transfer device 4 may further include: a conveying body 41 in a disc shape, a square disc shape or the like; a silicon rod positioning mechanism 43 arranged on the conveying body 41 and used for positioning the silicon rod; and the conversion driving mechanism is used for driving the conveying body 41 to rotate so as to drive the silicon rod positioning mechanism 43 to position the silicon rod conversion position.
As described above, the silicon rod processing platform in this embodiment includes the waiting location, the first processing location, the second processing location, and the third processing location, and for being adapted to these functional locations, the number of the silicon rod positioning mechanisms 43 on the conveying body 41 may be set to four, and each silicon rod positioning mechanism 43 may position at least one silicon rod. Further, the angles set between every two of the four silicon rod positioning mechanisms 43 are consistent with the angle distribution between every two of the four functional areas. Thus, when one silicon rod positioning mechanism 43 corresponds to one functional zone, inevitably, the other three silicon rod positioning mechanisms 43 also correspond to the other three functional zones, respectively. Thus, in the pipelining, when at least one silicon rod is positioned on each silicon rod positioning mechanism 43 and the silicon rod positioning mechanism 43 corresponds to a functional region, the silicon rods are positioned at a corresponding functional region to perform a corresponding processing operation, for example: the silicon rod in the waiting zone can be subjected to pretreatment operation, the silicon rod in the first processing zone can be subjected to first processing operation, the silicon rod in the second processing zone can be subjected to second processing operation, and the silicon rod in the third processing zone can be subjected to third processing operation. In an alternative embodiment, the waiting area, the first processing area, the second processing area, and the third processing area on the silicon rod processing platform are distributed at 90 ° with respect to each other, and therefore, correspondingly, the four silicon rod positioning mechanisms 43 on the conveying body 41 are also distributed at 90 ° with respect to each other. Of course, the number of the silicon rod positioning mechanisms 43 may be varied according to actual requirements, but is not limited thereto, for example, the number of the silicon rod positioning mechanisms 43 may be determined according to the number of the functional areas provided on the silicon rod processing platform.
In some embodiments, the silicon rod positioning mechanism 43 may further include: a rotary bearing platform 431, a rotary pressing device 433, a lifting driving device (not shown), and a rotary driving device (not shown).
A rotary bearing 431 is provided on the conveying body 41 in the silicon rod transfer device 4 for bearing the silicon rod 100(200) and for bringing the silicon rod 100(200) to a standing position, i.e. the bottom of the silicon rod 100(200) rests on the rotary bearing 431. In the present embodiment, the rotary susceptor 431 is rotated and rotated together with the rotation of the conveying body 41 in the silicon rod changing device 4. In some embodiments, the rotary susceptor 431 may also be configured to be capable of rotating, for example, the rotary susceptor 431 may have a rotation axis with respect to the conveying body 41 to realize a rotation motion, such that the rotary susceptor 431 and the silicon rod 100(200) thereon may rotate together after the silicon rod 100(200) is supported by the rotary susceptor 431. Further, the contact surface of the rotary susceptor 431 for contacting the silicon rod is damped to provide a certain friction force that can move the silicon rod. The rotary bearing 431 is adapted to the silicon rod 100(200), and in some embodiments, the rotary bearing 431 may be a circular bearing or a square bearing adapted to the cross-sectional size of the silicon rod 100 (200).
The rotary pressing device 433 is disposed above the rotary supporting platform 431 and presses against the top of the silicon rod 100(200) to press the silicon rod 100 (200). The rotary pressing device 433 may further include a support movably disposed and a pressing block disposed at the bottom of the support. The support is movably mounted on a central mounting frame, which is located in the central area of the conveying body 41 and rotates along with the conveying body 41. The top pressure movable block is matched with the silicon rod 100(200), and in an alternative embodiment, the top pressure movable block can be a cake-shaped pressing block or a square pressing block matched with the cross-sectional size of the silicon rod 100 (200). Further, the pressing movable block of the rotary pressing device 433 is pivotally connected to the support and can rotate relative to the support.
As can be seen from the foregoing, the rotary holder 431 is configured to rotate and the pressing movable block of the rotary pressing device 433 is pivotally connected to the support, so that the rotary holder 431 or the pressing movable block can be linked to a rotary driving device. In one case, when the rotary platform 431 is coupled to a rotary driving device, the rotary platform 431 serves as a driving rotating component and the pressing movable block serves as a driven rotating component; in another case, when the pressing movable block is linked to a rotation driving device, the pressing movable block serves as a driving rotation member and the rotation platform 431 serves as a driven rotation member.
In practical applications, the rotary pressing device 433 can cooperate with the rotary supporting platform 431 therebelow, specifically, after the silicon rod 100(200) is vertically placed on the rotary supporting platform 431, the lifting driving device drives the support to move downwards along the central mounting frame until the pressing movable block on the support presses against the top of the silicon rod 100 (200). Subsequently, when the silicon rod 100(200) needs to be rotated, the rotary bearing platform 431 or the jacking movable block which is linked with the rotary driving device is driven to rotate by the rotary driving device, and the silicon rod 100(200) is driven to rotate together by the friction force among the rotary bearing platform 431, the silicon rod 100(200) and the jacking movable block, so that the operation surface or the operation area in the silicon rod 100(200) is adjusted, and the adjusted operation surface or the adjusted operation area in the silicon rod 100 is processed. The rotation speed and the rotation angle of the silicon rod 100(200) may be controlled by the rotation driving device. In a specific implementation manner, the lifting driving device may be, for example, an air cylinder or a lifting motor, and the rotation driving device may be, for example, a rotating motor.
Further, as can be seen from the above, in some cases, the rotary carrying platform 431 or the pressing movable block may be controlled by the rotary driving device to rotate to drive the silicon rod 100(200) to rotate to change the working surface or the working area, and sometimes, when the silicon rod 100(200) rotates to the required working surface or working area, the silicon rod needs to be stopped and positioned to receive the processing operation of the processing device in the corresponding functional area. Therefore, in the present application, the silicon rod positioning mechanism may also be provided with a locking mechanism, if necessary. In one implementation, a carrier locking mechanism (not shown) may be provided at the bottom of the central mounting frame and adjacent to the rotary carrier 431, and may include a lock bolt and a lock cylinder coupled to the lock bolt. In practical application, when the rotary bearing platform 431 needs to be locked, a locking cylinder in the bearing platform locking mechanism drives a locking bolt to extend out and act on the bottom or the neck of the rotary bearing platform 431, so that the rotary bearing platform 431 is ensured to be stable and immovable; when the silicon rod needs to be rotated to change the working surface or the working area, the locking cylinder in the bearing table locking mechanism drives the locking bolt to contract, so that the rotary bearing table 431 is unlocked, and the rotary bearing table 431 can rotate.
The conveying body 41 is driven by the switching driving mechanism to rotate, and the silicon rod positioning mechanism 43 on the conveying body 41 and the silicon rod 100(200) positioned by the silicon rod positioning mechanism 43 are switched between different functional areas through the rotation of the conveying body 41.
In some embodiments, the transition drive mechanism further comprises: a conversion toothed belt provided on the circumferential side of the conveying body 41; the silicon rod processing device comprises a driving motor and a linkage structure which is connected with the driving motor and driven by the driving motor, the linkage structure is arranged on a silicon rod processing platform of the base 1, and the linkage structure comprises a rotating gear meshed with the conversion toothed belt. Thus, the rotating gear drives the conveying body 41 to rotate under the driving of the driving motor to drive the silicon rod positioning mechanism 43 and the silicon rod 100(200) thereon to be converted to other functional areas to complete conveying, and the driving motor can be a servo motor.
In certain embodiments, the silicon rod transfer device 4 may further comprise a locking mechanism (not shown in the figures) for locking the conveying body 41. For example, the locking mechanism may include a plurality of locking bolts and a locking cylinder connected to the locking bolts, where the number of the locking bolts may be multiple and the locking bolts are uniformly distributed at the edge of the conveying body 41 (for example, the number of the locking bolts is four and the locking bolts are uniformly distributed in a 90 ° angle manner), and in practical applications, when the silicon rod needs to be transferred from a certain processing region to another processing region, the locking cylinder drives the locking bolts to contract to unlock the disc-shaped or ring-shaped conveying body, so that the conveying body 41 can rotate; after the silicon rod is converted, that is, after the silicon rod is converted from a certain processing region to a target processing region, the locking cylinder in the locking mechanism drives the locking bolt to extend out and act on the conveying body 41, so as to lock the conveying body 41.
As mentioned above, the silicon rods located at the waiting area can be pretreated. This application silicon rod surely grinds all-in-one still includes silicon rod transfer device 6, and the neighbour locates silicon rod processing platform's waiting position for shift silicon rod 100(200) to treat processing to the waiting position of silicon rod processing platform or will wait that the silicon rod after the processing on the position shifts out silicon rod processing platform.
Referring to fig. 3, a partial enlarged view of a portion a of fig. 1 is shown. As shown in fig. 3, the silicon rod transfer device 6 further includes: a transferring base 61, a silicon rod platform 63 and a platform turnover mechanism.
The transferring base 61 is slidably disposed on the machine base 1 through a sliding mechanism. In this embodiment, the sliding mechanism can realize sliding in at least two directions. For example, the sliding mechanism includes a support portion 621, a switching portion 623, a first direction sliding unit disposed between the support portion 621 and the switching portion 623, and a second direction sliding unit disposed between the switching portion 623 and the transfer base 61, wherein the first direction sliding unit may include a first direction slide rail, a first direction slider or slide bar corresponding to the first direction slide rail, and a first direction driving source, and the second direction sliding unit may include a second direction slide rail, a second direction slider or slide bar corresponding to the second direction slide rail, and a second direction driving source.
Wherein, first slide rail, first direction slider or draw runner, second slide rail, second direction slider or draw runner are laid with the horizontality, any one in first direction driving source and the second direction driving source can include: a sliding rack, a rotating gear (not shown in the drawing) meshed with the sliding rack and a sliding driving motor. In the first direction sliding unit, the first driving source can drive the converting portion 623 and the transfer base 61 thereon to slide along the first direction by the first direction slider or slider and the first direction slide rail. And a second direction sliding unit, wherein the second driving source can drive the transfer base 61 to slide along the second direction through a second direction sliding block or strip and a second direction sliding rail.
In some examples, the first direction may be, for example, a left-right direction (i.e., an X-axis direction in fig. 2 and 3), and the second direction may be, for example, a front-back direction (i.e., a Y-axis direction in fig. 2 and 3).
The silicon rod platform 63 is movably provided on the transfer base 61, and serves to laterally (i.e., horizontally) position the silicon rod 100 (200). In the present embodiment, the silicon rod platform 63 is a plate-shaped structure or a frame structure, and at least one silicon rod supporting bracket is disposed at least at the front and rear ends of the silicon rod platform 63, respectively, for supporting the front and rear ends of the silicon rod 100(200), so that the silicon rod 100(200) can be laterally disposed. Meanwhile, stopper structures may be provided at both left and right sides of the silicon rod platform, respectively, for restricting movement of the silicon rod 100(200) in the left and right directions.
It is known that the silicon rod 100 needs to be converted from a horizontal state (horizontal placement) to an upright state (vertical placement) in a subsequent processing operation, and therefore, in the present application, a silicon rod fastening mechanism may also be provided for fastening the silicon rod (not shown in the drawings) during the silicon rod transfer. In certain embodiments, the silicon rod fastening mechanism may comprise a fastening jaw and a fastening motor or a fastening cylinder controlling the fastening jaw. Furthermore, the silicon rod fastening mechanism comprises at least two pairs of fastening claws, wherein the at least two pairs of fastening claws correspond to the two silicon rod support brackets respectively, namely, one pair of fastening claws corresponds to one silicon rod support bracket, two fastening claws of the pair of fastening claws are oppositely arranged on the left side and the right side of the silicon rod support bracket respectively, and each fastening claw is provided with a fastening motor or a fastening air cylinder. In practical applications, when the silicon rod 100(200) is lying on the silicon rod platform, the fastening motor or the fastening cylinder drives the respective corresponding fastening jaw towards the silicon rod 100(200) on the silicon rod platform, so that the silicon rod 100(200) is fastened as a whole by the cooperation of at least two pairs of fastening jaws. Preferably, the pressing place where the fastening jaws come into contact with the silicon rod 100(200) may be provided with a buffer member to avoid or reduce damage to the silicon rod 100 (200).
In order to convert the silicon rod 100 from the horizontal state (horizontal placement) to the vertical state (vertical placement), the silicon rod transfer device 6 further includes a platform-overturning mechanism. The platform turnover mechanism is used for driving the silicon rod platform 63 to turn over relative to the transfer base 61, so that the silicon rod 100(200) is vertically placed on the silicon rod conversion device 4. In this embodiment, the platform turnover mechanism includes: mounting bracket, removal frame, upset cylinder or upset motor, upset rack and upset gear. The mounting bracket is fixedly arranged on the transferring base. In some embodiments, the mounting bracket is a plate-like structure or a frame structure. The movable frame is movably arranged above the mounting frame. In some embodiments, the movable frame is a hollow plate-like structure or a frame structure. Further, the left and right opposite sides of the position adjacent to the silicon rod conversion device 4 in the movable frame are respectively provided with a turnover rack, correspondingly, the left and right opposite sides of the turnover end adjacent to the silicon rod conversion device 4 in the silicon rod platform 63 are respectively provided with a turnover gear, and the turnover gear is correspondingly arranged on and meshed with the turnover rack. The overturning cylinder or the overturning motor is used for driving the moving frame to move relative to the mounting frame. Taking a turning cylinder as an example, the turning cylinder is integrally arranged in a hollow area of the moving frame, specifically, a cylinder body (for example, including a cylinder barrel and a piston) in the turning cylinder is arranged on the mounting frame, and a piston rod in the turning cylinder is connected to the moving frame. In practical application, aiming at the problem that the silicon rod platform is turned from a horizontal state to a vertical state: the upset cylinder actuates, and the piston rod extends and promotes the carriage for the carriage moves relative mounting bracket under promoting, and the upset rack on the carriage also follows the carriage and removes, rotates under the drive of upset rack with upset rack engaged with upset gear on the silicon rod platform, thereby drives the silicon rod platform and overturns, finally realizes that the silicon rod platform is overturned into vertical state by the horizontality. Aiming at the problem that the silicon rod platform is turned from a vertical state to a horizontal state: the upset cylinder actuates, and the piston rod contracts and stimulates the carriage for the carriage moves relative mounting bracket under promoting, and the upset rack on the carriage also follows the carriage and removes, rotates under the drive of upset rack with upset rack engaged with upset gear on the silicon rod platform, thereby drives the silicon rod platform and overturns, finally realizes that the silicon rod platform overturns into the horizontality by vertical state.
What is needed is: in addition, in order to enable the movable frame to smoothly and stably move relative to the mounting frame, slide rails are arranged on the left and right opposite sides of the mounting frame, and slide blocks or slide bars for sliding on the slide rails are arranged on the left and right opposite sides of the bottom of the movable frame. For example, in other embodiments, the slide rail may be disposed on the movable frame instead, and the slide block or the slide bar may be disposed on the mounting frame instead. Furthermore, in order to avoid or reduce the collision damage of the silicon rod platform to the movable frame, the mounting frame or the overturning cylinder or the overturning motor in the overturning process (for example, when the silicon rod platform is overturned from the vertical state to the horizontal state), a relatively convex buffer can be further arranged on the movable frame or the mounting frame.
The silicon rod transfer device 6 may further include a lifting mechanism. The lifting mechanism is arranged on the silicon rod platform and used for lifting the turned silicon rod 100 (200). In this embodiment, the lifting mechanism may include a slide rail or a slide rod and a lifting motor or a lifting cylinder, wherein to realize the lifting motion of the silicon rod 100(200), the silicon rod support bracket is disposed on the silicon rod platform through the slide rail or the slide rod (the silicon rod fastening mechanism is mounted on the silicon rod support bracket), and the lifting motor or the lifting cylinder controls the silicon rod support bracket (together with the silicon rod fastening mechanism) to perform the lifting motion, so as to drive the silicon rod 100(200) to realize the lifting motion. Still take the lifting cylinder as an example, the whole lifting cylinder is arranged in the middle of the silicon rod platform, specifically, the cylinder body (for example, including the cylinder barrel and the piston) in the lifting cylinder is arranged on the silicon rod platform, and the piston rod in the lifting cylinder is connected to the silicon rod support bracket. In practical application, the lifting cylinder is actuated, the piston rod stretches (extends or contracts) and pushes and pulls (pushes or pulls) the silicon rod support bracket, so that the silicon rod support bracket moves up and down relative to the mounting frame under pushing and pulling, and the silicon rod 100(200) on the silicon rod support bracket also moves up and down along with the silicon rod support bracket.
The silicon rod transfer device 6 is only an exemplary one, but not limited thereto, and other variations of the silicon rod transfer device may be made.
In certain embodiments, the silicon rod transfer device may include: the silicon rod fixture comprises a reversing carrier, a silicon rod fixture arranged on the reversing carrier and a reversing driving mechanism used for driving the reversing carrier to do reversing motion.
The reversing carrier is a main body device used for arranging other various components in the silicon rod transfer device, the other various components mainly comprise a silicon rod clamp, but not limited to the silicon rod clamp, and the other components can also be a mechanical structure, an electrical control system, numerical control equipment and the like. In this embodiment, the reversing carrier may include a base, a top frame opposite to the base, and a supporting structure disposed between the base and the top frame. In addition, the reversing carrier has another important function of supporting the reversing conversion of the silicon rod clamp through reversing movement. The reversing vehicle can be moved in a reversing manner, for example, by means of a reversing drive. By using the reversing driving mechanism, the reversing carrier can be driven to perform reversing motion so that the silicon rod clamp on the reversing carrier clamps the silicon rod 100 to be processed and transfers the silicon rod from the loading and unloading area to the waiting area, or clamps the processed silicon rod 200 corresponding to the waiting area and transfers the silicon rod from the waiting area to the loading and unloading area.
In a specific implementation manner, the reversing driving mechanism for realizing the reversing motion of the reversing carrier can comprise a rotating shaft and a rotating motor, and the reversing carrier is connected with the installation foundation structure below the reversing carrier through the rotating shaft. When the steering movement is implemented, the rotating motor is started to drive the rotating shaft to rotate so as to drive the reversing carrier to rotate to realize the reversing movement. The aforementioned rotation of the drive rotation shaft can be designed as a unidirectional rotation, which can be, for example, a unidirectional clockwise rotation or a unidirectional counterclockwise rotation, and also as a bidirectional rotation, which can be, for example, a clockwise rotation and a counterclockwise rotation. In addition, the angle at which the driving rotation shaft rotates may be set according to the actual configuration of the silicon rod transfer device. Moreover, the base in the reversing carrier can adopt a disc structure, a rectangular disc or an elliptical disc, and the central position of the base is connected with the rotating shaft, but the shape of the base is not limited to the above, and in other embodiments, the base can also adopt other shapes.
And a silicon rod clamp is arranged on the reversing carrier and used for clamping a corresponding silicon rod. For example, in some embodiments, a silicon rod clamp is arranged on a certain mounting surface of the reversing carrier, and the silicon rod clamp may include at least two silicon rod clamping parts, wherein the at least two silicon rod clamping parts are arranged at intervals. The silicon rod holder in the silicon rod clamp may be used for holding a round silicon rod (i.e. a silicon rod to be processed) as well as a square silicon rod (i.e. a processed silicon rod). Therefore, the silicon rod clamp on the reversing carrier is switched between the loading and unloading area and the waiting area to transfer the silicon rod to be processed and between the waiting area and the loading and unloading area to transfer the processed silicon rod by driving the reversing carrier to perform reversing motion. In practical applications, the rotation angle of the reversing carrier for reversing motion is determined according to the position relationship between the loading and unloading area and the waiting area. In some embodiments, the loading and unloading area and the waiting area are arranged oppositely, and the silicon rod transfer device is positioned between the loading and unloading area and the waiting area, so that the reversing carrier is driven by the reversing driving mechanism to rotate by 180 degrees. In some embodiments, the loading and unloading area and the waiting area are disposed at an angle of 90 °, and the reversing carrier is driven by the reversing driving mechanism to rotate at an angle of 90 °. However, no matter how, the positional relationship between the loading and unloading area and the waiting area is not particularly limited, and the arrangement order and the arrangement angle therebetween can be changed, so long as unnecessary interference is not generated between the stations, and thus the rotation direction and the rotation angle of the reversing carrier can be adjusted adaptively.
In certain embodiments, both the silicon rod to be processed and the processed silicon rod are placed vertically, so that at least two silicon rod holders of the silicon rod clamp are spaced up and down. Any one of the silicon rod holders may further comprise: the reversing carrier comprises a clamping arm mounting seat and two clamping arms, wherein the clamping arm mounting seat is arranged on the reversing carrier, and at least two clamping arms are movably arranged on the clamping arm mounting seat. The two clamping arms are arranged in bilateral symmetry, and the two clamping arms can form a clamping space for clamping a single-crystal-circle silicon rod or a silicon cube. Additionally, the silicon rod clamping piece can have the function of centering adjustment. In general, when the clamping arms in the silicon rod clamping part are in a clamping state, the center of the clamping space formed by the two clamping arms coincides with the center of the silicon rod to be processed and the center of the processed silicon rod. Therefore, when the silicon rod clamping piece is used for clamping a vertically placed silicon rod to be processed or a processed silicon rod, the two clamping arms in the silicon rod clamping piece are contracted and are abutted against the silicon rod to be processed or the processed silicon rod by the clamping arms. In the process that the clamping arms shrink and clamp the silicon rod to be processed or the processed silicon rod, the silicon rod to be processed or the processed silicon rod is pushed by the two clamping arms at two sides and moves towards the central area of the clamping space until the silicon rod to be processed or the processed silicon rod is clamped by the two clamping arms in the silicon rod clamping piece, and at the moment, the center of the silicon rod to be processed or the processed silicon rod can be located at the center of the clamping space of the silicon rod clamping piece.
In order to enable the at least two clamping arms in the silicon rod clamping part to smoothly and stably clamp silicon rods to be processed or processed silicon rods with different sizes, at least one of the clamping arms in the silicon rod clamping part is of an adjustable design. Taking two clamping arms as an example, at least one of the two clamping arms is designed to be movable (one or two of the two clamping arms are designed to be movable), so that the clamping distance between the two clamping arms can be adjusted.
In addition, the silicon rod clamp in the silicon rod transfer device of the present application may have other variations. For example, the silicon rod transfer device may be provided with two silicon rod clamps, which may be respectively disposed on two opposite mounting surfaces of the reversing carrier. And, the two silicon rod clamps may be the same or different. In embodiments where two silicon rod furniture are identical, the two silicon rod clamps are used to clamp a round and a square silicon rod. In an embodiment in which the two silicon rod fixtures are not identical, one of the two silicon rod fixtures is used for holding a round silicon rod and the other silicon rod fixture is used for holding a square silicon rod.
Furthermore, the silicon rod transfer device 6 according to the present application may further provide movement in at least one direction. For example, the silicon rod transfer device may further include a forward and backward direction advancing and retreating mechanism, and the advancing and retreating mechanism may include: the reversing device comprises a forward and backward guide rail and a forward and backward motor, wherein the forward and backward guide rail is arranged along the front and back direction, and a base of the reversing carrier can be rested on the forward and backward guide rail through a sliding block.
This application silicon rod surely grinds all-in-one still includes location detection device. In the present exemplary embodiment, the position detection device (not shown in the figures) serves for the edge detection and the centering of the silicon rod 100 located at the waiting position.
The positioning detection device further includes: ridge line detection unit and axle center adjusting unit.
In some embodiments, the ridge line detection unit includes a contact detection mechanism for sending an on-off signal to a detection controller by contacting with the ridge line of the silicon rod, a rotation mechanism for adjusting the position of the silicon rod according to the control of the detection controller, and a detection controller electrically connected to the contact detection mechanism and the rotation mechanism.
The number of the silicon rod positioning mechanisms 43 may vary according to practical requirements, but is not limited thereto, for example, the number of the silicon rod positioning mechanisms 43 may be determined according to the number of the functional areas provided on the silicon rod processing platform.
In some embodiments, the silicon rod positioning mechanism 43 may further include: a rotary bearing platform 431,
In certain embodiments, the axis adjusting unit is configured to position the axis of silicon rod 100 at the center of the waiting location, and comprises a clamping mechanism configured to form a clamping space for clamping the silicon rod, and the center of the clamping space coincides with the center of the waiting location.
In a specific implementation, the clamping mechanism may include at least two clamping members, and each clamping member may include at least two clamping arms.
In view of the circular cross-section of the silicon rod, in some examples, the clamping element as a whole is a circular workpiece holder, the two clamping arms forming the clamping element are of symmetrical design, the single clamping arm is designed to have an arc-shaped clamping surface, preferably, the arc-shaped clamping surface of the single clamping arm exceeds 100-quarter of the arc of the silicon rod, and thus, the arc-shaped clamping surface of the clamping element formed by the two clamping arms exceeds 100-half of the arc of the silicon rod. Certainly, the arc-shaped clamping surface in the clamping arm can be additionally provided with a buffer cushion for avoiding the damage to the surface of the silicon rod in the process of clamping the silicon rod and playing a good role in protecting the silicon rod. In general, when the clamping arms of the clamping member are in a clamped state, the center of the clamping space formed by the two clamping arms coincides with the center of the silicon rod 100. Therefore, when the silicon rod 100 vertically placed on the to-be-processed region is clamped by the clamping member, the two clamping arms of the clamping member are contracted and abutted against the silicon rod by the arc-shaped clamping surfaces of the clamping arms. During the process of contracting and clamping silicon rod 100 by the clamping arms, silicon rod 100 is pushed by the two clamping arms on both sides and moves towards the central region of the clamping space until silicon rod 100 is clamped by the clamping arms in the clamping member, at which time, the center of silicon rod 100 can be located at the center of the clamping space of the clamping member.
After the silicon rod 100 to be processed is transferred to the waiting location of the silicon rod processing platform by the silicon rod transfer device 6 and is pretreated, the silicon rod may be transferred from the waiting location to another processing location by the silicon rod transfer device 4.
The cutting device 2 is arranged on the base 1 and is used for cutting the silicon rod 100 on the first processing position of the silicon rod processing platform in the first direction and cutting the silicon rod 100 on the second processing position of the silicon rod processing platform in the second direction to form a square silicon rod.

The cutting support 22 can be moved up and down relative to the cutting frame 21 and the machine base 1 by means of a lifting guide and the lifting slide, driven by the lifting motor (which can be, for example, a servo motor).
In the present embodiment, since the cutting support 22 may be provided with the first cutting unit 23 and the second cutting unit 25, that is, the first cutting unit 23 and the second cutting unit 25 share the cutting support 22. Thus, in the present embodiment, on the one hand, the cutting frame 21 and the cutting support 22 of the cutting device 2 are provided in a central position between the first and second machining locations.

For example, in some embodiments, the holder body 221 in the cutting holder 22 is disposed at 45 ° to the X-axis or Y-axis, the first holder flap 223 is disposed at 145 ° to the holder body 221 and is disposed along the Y-axis, and the second holder flap 225 is disposed at 145 ° to the holder body 221 and is disposed along the X-axis.
The first cutting unit 23 is disposed at a first side of the cutting support 22, and is configured to perform first-direction side cutting on the silicon rod 100 at the first processing location of the silicon rod processing platform.

Specifically, the first cutting unit 23 includes a first bobbin 231 disposed on the first support wing 223, a plurality of first cutting wheels 233 disposed on the first bobbin 231, and a first cutting line 235, wherein the first cutting line 235 sequentially winds the plurality of first cutting wheels 233 to form a first cutting line segment disposed in a first direction. In this embodiment, the first direction is an X-axis direction.
In practical applications, the first cutting unit 23 may include at least four first cutting wheels 233, and the four first cutting wheels 233 may be combined into a pair of first cutting wheel sets, that is, one first cutting wheel set is formed by two first cutting wheels oppositely arranged along the first direction (i.e., along the X-axis direction), and one pair of first cutting wheel sets is formed by two first cutting wheel sets arranged along the second direction (i.e., along the Y-axis direction). Specifically, the first cutting unit 23 includes a pair of first cutting wheel sets, which may include two first cutting wheel sets that are respectively arranged at the left and right sides of the first bobbin 231 in the second direction (i.e., in the Y-axis direction), wherein one first cutting wheel set is located at the left side of the first bobbin 231 and includes two first cutting wheels 233 arranged in the first direction (i.e., in the X-axis direction), and the other first cutting wheel set is located at the right side of the first bobbin 231 and includes two first cutting wheels 233 arranged in the first direction (i.e., in the X-axis direction).
The first cutting lines 235 are sequentially wound around the first cutting wheels 233 of the first cutting unit 23 to form a first wire mesh. In practical applications, the first cutting line 235 sequentially winds around the four first cutting wheels 233 of the first cutting unit 23 to form two first cutting line segments, and the two first cutting line segments are arranged along the X axis and parallel to each other to form a first cutting line network. Specifically, the first cutting line 235 forms one first cutting line segment after being wound around two first cutting wheels 233 arranged in one first cutting wheel set along the first direction (i.e., along the X-axis direction), and the first cutting line 235 forms another first cutting line segment after being wound around two first cutting wheels 233 arranged in another first cutting wheel set along the first direction (i.e., along the X-axis direction). In this way, the two first cutting wire sections parallel to each other cooperate to form a first cutting wire web which is "in the shape of a word" in the first direction (i.e. in the direction of the X axis).
Of course, the first cutting unit 23 is not limited to the embodiment shown in fig. 1 to 3, and other variations can be made in other embodiments.
In some embodiments, the first cutting unit 23 may comprise at least four first cutting wheels 233, and the four first cutting wheels 233 may be combined into a pair of first cutting wheel sets, that is, one first cutting wheel set is formed by two first cutting wheels oppositely arranged along the Y-axis, and one first cutting wheel set is formed by two first cutting wheel sets along the X-axis. Specifically, the first cutting unit 23 includes a pair of first cutting wheel sets, which may include two first cutting wheel sets that are respectively arranged at front and rear sides of the first bobbin 231 in the first direction (i.e., in the X-axis direction), wherein one first cutting wheel set is located at a front side of the first bobbin 231 and includes two first cutting wheels 233 arranged in the second direction (i.e., in the Y-axis direction), and the other first cutting wheel set is located at a rear side of the first bobbin 231 and includes two first cutting wheels 233 arranged in the second direction (i.e., in the Y-axis direction). The first cutting lines 235 are sequentially wound around the first cutting wheels 233 of the first cutting unit 23 to form a first wire mesh. In practical applications, the first cutting line 235 sequentially winds around the four first cutting wheels 233 arranged in the first cutting unit 23 to form two first cutting line segments, and the two first cutting line segments are arranged along the second direction (i.e. along the Y-axis direction) and are parallel to each other to form a first cutting line network. Specifically, the first cutting line 235 forms one first cutting line segment after being wound around the two first cutting wheels 233 arranged in the second direction (i.e., along the Y-axis direction) in one first cutting wheel set, and the first cutting line 235 forms another first cutting line segment after being wound around the two first cutting wheels 233 arranged in the second direction (i.e., along the Y-axis direction) in the other first cutting wheel set. In this way, the two first cutting wire segments parallel to each other cooperate to form a first cutting wire web that is "═ shaped" in the second direction (i.e., in the Y-axis direction).
In some embodiments, the number of first cutting wheels 233 and first cutting line segments in the first cutting unit 23 may vary. For example, the first cutting unit includes two first cutting wheels, the two first cutting wheels are oppositely disposed along a first direction (i.e., along the X-axis direction) or along a second direction (i.e., along the Y-axis direction), and the first cutting line sequentially winds around the two first cutting wheels in the first cutting unit to form a first cutting line segment in a shape of "one" along the first direction (i.e., along the X-axis direction) or along the second direction (i.e., along the Y-axis direction) as a first cutting line web.
In addition, in the present embodiment, the first cutting unit 23 may further include at least one of: a guide roller provided on the first bobbin 231 and/or the first holder side 223 for guiding the first cutting wire 235; a tension pulley provided on the first bobbin 231 and/or the first holder side 223 for adjusting the tension of the first cutting line 235; and a wire storage cylinder (the wire storage cylinder can further comprise a pay-off cylinder and a take-up cylinder) arranged on the base 1 and used for winding and unwinding the first cutting wire.
The second cutting unit 25 is disposed at a second side of the cutting support 22, and is configured to perform second-direction side cutting on the silicon rod 100 at a second processing location of the silicon rod processing platform.
In the present embodiment, as previously described, the cutting support 22 includes a support main body 221 and first and second support wings 223 and 225 located on opposite sides of the support main body 221, and thus, the second cutting unit 25 is mounted at the second support wing 225 of the cutting support 22. Specifically, the second cutting unit 25 includes a second bobbin 251 disposed on the second support wing 225, a plurality of second cutting wheels 253 disposed on the second bobbin 251, and a second cutting line 255, and the second cutting line 255 sequentially winds around the plurality of second cutting wheels 253 to form a second cutting line segment disposed in the second direction. In this embodiment, the second direction is a Y-axis direction.
In practical applications, the second cutting unit 25 may include at least four second cutting wheels 253, and the four second cutting wheels 253 may be combined into a pair of second cutting wheel sets, that is, two second cutting wheels oppositely disposed along the second direction (i.e., along the Y-axis direction) form one second cutting wheel set, and two second cutting wheel sets along the first direction (i.e., along the X-axis direction) form one second cutting wheel set. Specifically, the second cutting unit 25 includes a pair of second cutting wheel groups, which may include two second cutting wheel groups that are arranged at left and right sides of the second bobbin 251 in the first direction (i.e., in the X-axis direction), wherein one second cutting wheel group is located at a left side of the second bobbin 251 and includes two second cutting wheels 253 arranged in the second direction (i.e., in the Y-axis direction), and the other second cutting wheel group is located at a right side of the second bobbin 251 and includes two second cutting wheels 253 arranged in the second direction (i.e., in the Y-axis direction).
The second cutting lines 255 sequentially wind around each of the second cutting wheels 253 of the second cutting unit 25 to form a second cutting line net. In practical applications, the second cutting lines 255 sequentially wind around the four second cutting wheels 253 of the second cutting unit 25 to form two second cutting line segments, and the two second cutting line segments are arranged along a second direction (i.e. along the Y-axis direction) and are parallel to each other to form a second cutting line network. Specifically, the second cutting line 255 is wound around two second cutting wheels 253 arranged in a second direction (i.e., along the Y-axis direction) in one second cutting wheel group to form one second cutting line segment, and the second cutting line 255 is wound around two second cutting wheels 253 arranged in a second direction (i.e., along the Y-axis direction) in another second cutting wheel group to form another second cutting line segment. In this way, the two second cutting line segments parallel to each other cooperate to form a second cutting line web that is "in the shape of a letter" in the second direction (i.e., in the Y-axis direction).
Of course, the second cutting unit 25 is not limited to the embodiment shown in fig. 1 to 3, and other variations can be made in other embodiments.
In some embodiments, the second cutting unit 25 may include at least four second cutting wheels 253, and the four second cutting wheels 253 may be combined into a pair of second cutting wheel sets, that is, one second cutting wheel set is formed by two second cutting wheels oppositely arranged along the first direction (i.e., along the X-axis direction), and one second cutting wheel set is formed by two second cutting wheel sets along the second direction (i.e., along the Y-axis direction). Specifically, the second cutting unit 25 includes a pair of second cutting wheel groups, which may include two second cutting wheel groups that are arranged at both front and rear sides of the second bobbin 251 in the second direction (i.e., in the Y-axis direction), wherein one second cutting wheel group is located at a front side of the second bobbin 251 and includes two second cutting wheels 253 arranged in the first direction (i.e., in the X-axis direction), and the other second cutting wheel group is located at a rear side of the second bobbin 251 and includes two second cutting wheels 253 arranged in the first direction (i.e., in the X-axis direction). The second cutting lines 255 sequentially wind around each of the second cutting wheels 253 of the second cutting unit 25 to form a second cutting line net. In practical applications, the second cutting lines 255 sequentially wind around the four second cutting wheels 253 of the second cutting unit 25 to form two second cutting line segments, and the two second cutting line segments are arranged along the first direction (i.e. along the X-axis direction) and are parallel to each other to form a second cutting line network. Specifically, the second cutting line 255 is wound around two second cutting wheels 253 arranged in a first direction (i.e., along the X-axis direction) in one second cutting wheel group to form one second cutting line segment, and the second cutting line 255 is wound around two second cutting wheels 253 arranged in a first direction (i.e., along the X-axis direction) in another second cutting wheel group to form another second cutting line segment. In this way, the two second cutting line segments parallel to each other cooperate to form a second cutting line web that is "in the shape of a letter" in the first direction (i.e., in the direction of the X axis).
In some embodiments, the number of second cutting wheels 253 and second cutting line segments in the second cutting unit 25 may be varied. For example, the second cutting unit includes two second cutting wheels, the two second cutting wheels are oppositely disposed along a second direction (i.e., along the Y-axis direction) or along a first direction (i.e., along the X-axis direction), and the second cutting lines sequentially wind around the two second cutting wheels disposed in the second cutting unit to form a second cutting line segment in a shape of a straight line along the second direction (i.e., along the Y-axis direction) or along the first direction (i.e., along the X-axis direction) as a second cutting line web.
In addition, in the present embodiment, the second cutting unit 25 may further include at least one of: a wire guide wheel arranged on the second wire frame 251 and/or the second support flank 225 for guiding the second cutting wire 255; a tension pulley provided on the second string carrier 251 and/or the second holder wing 225 for adjusting the tension of the second cutting string 255; and a wire storage cylinder (the wire storage cylinder can further comprise a pay-off cylinder and a take-up cylinder) arranged on the machine base 1 and used for winding and unwinding the second cutting wire.
Further, the first cutting line 235 in the first cutting unit 23 and the second cutting line 255 in the second cutting unit 25 are aligned.
In some embodiments, the first cutting unit 23 and the second cutting unit 25 are two independent cutting units, and the first cutting line 235 in the first cutting unit 23 and the second cutting line 255 in the second cutting unit 25 may be two independent cutting lines.
In certain embodiments, the first cutting line 235 in the first cutting unit 23 and the second cutting line in the second cutting unit 25 may be the same cutting line. In this case, the common cutting lines sequentially wind the plurality of first cutting wheels 233 disposed in the first cutting unit 23 to form a first cutting line net, and then are transferred to the second cutting unit at the side to sequentially wind the plurality of second cutting wheels 253 disposed in the second cutting unit 25 to form a second cutting line net. In this embodiment, therefore, the cutting support 22 is also provided with one or more guide wheels around which the common cutting line is wound, between the first cutting unit 23 and the second cutting unit 25. Specifically, in the embodiment shown in fig. 2, a guide wheel 26 around which the common cutting line is wound is provided on the holder body 221 between the first cutting unit 23 and the second cutting unit 25 in the cutting holder 22. The first cutting unit 23 and the second cutting unit 25 share the same cutting line, so that the structure of the cutting unit can be simplified (for example, a set of paying-off cylinder and a set of winding cylinder are omitted), the integrity is good, the winding process is simplified, the efficiency is improved, and the line tension and the like of the two cutting units can be better controlled.
When the silicon rods on the first processing location and the silicon rods on the second processing location of the silicon rod processing platform are cut by means of the cutting device 2 in the embodiment shown in figure 2, the cutting support 22 is driven to descend relative to the cutting frame 21, the silicon rod on the first processing position and the silicon rod on the second processing position corresponding to the first cutting unit 23 and the second cutting unit 25 on the left side and the right side of the cutting support 22 are simultaneously cut, the first cutting unit 23 performs side cutting on the silicon rod in the first processing area along a first direction (i.e., along the X-axis direction) (the first cutting unit 23 is provided with a first cutting wire net in a shape of a Chinese character ═ along the X-axis direction), and the second cutting unit 25 performs side cutting on the silicon rod in the second processing area along a second direction (i.e., along the Y-axis direction) (the second cutting unit 25 is provided with a second cutting wire net in a shape of a Chinese character ═ along the Y-axis direction). Of course, in other embodiments, if the first cutting unit 23 is provided with a first cutting wire web in a shape of "═ type" in the second direction (i.e., in the Y-axis direction), the first cutting unit 23 performs side cutting of the silicon rod at the first processing location in the second direction (i.e., in the Y-axis direction), and likewise, if the second cutting unit 25 is provided with a first cutting wire web in a shape of "═ type" in the first direction (i.e., in the X-axis direction), the first cutting unit 23 performs side cutting of the silicon rod at the first processing location in the first direction (i.e., in the X-axis direction). As can be seen, in the present embodiment, the first cutting unit 23 and the second cutting unit 25 in the cutting device 2 share the cutting support 22, and by driving the shared cutting support 22 to perform the lifting motion, the first cutting unit 23 and the second cutting unit 25 thereon can perform the side cutting of the silicon rod at the first processing location along the first direction (i.e., along the X-axis direction) and the side cutting of the silicon rod at the second processing location along the second direction (i.e., along the Y-axis direction), respectively, at the same time. The cutting device 2 is simple in structure on the whole, convenient to control and capable of improving the cutting efficiency and quality of the silicon rod.
It should be noted that, in the present embodiment, the intersection point of the first cutting line 235 when the first cutting unit 23 performs the first-direction side cutting on the silicon rod 100 and the second cutting line 255 when the second cutting unit 25 performs the second-direction side cutting on the silicon rod 100 is located in the cross section of the silicon rod 100 (including the case that the intersection point is located on the circumference of the cross section), so that the formed square silicon rod has a cross section as large as possible (the surface area of the silicon wafer obtained after the subsequent slicing is large), and the material loss in the subsequent grinding (such as surface grinding and chamfering) operation can be reduced, thereby improving the utilization rate of the silicon material. Referring to fig. 5 and 6, fig. 5 is a schematic cross-sectional view showing that an intersection point of a first cutting line when the first cutting unit performs the first-direction side surface cutting on the silicon rod and a second cutting line when the second cutting unit performs the second-direction side surface cutting on the silicon rod is located inside a cross section of the silicon rod, fig. 6 is a schematic cross-sectional view showing that an intersection point of the first cutting line when the first cutting unit performs the first-direction side surface cutting on the silicon rod and the second cutting line when the second cutting unit performs the second-direction side surface cutting on the silicon rod is located on a circumference of the cross section of the silicon rod, and 101 shown in fig. 5 and 6 is a flaw-piece formed after the silicon rod is cut.
With the above-described slicing apparatus 2, after the first slicing operation (the first-direction side-cutting operation of the silicon rod 100 by the first slicing unit 23) and the second slicing operation (the second-direction side-cutting operation of the silicon rod 100 by the second slicing unit 25) are performed on the silicon rod 100, a square silicon rod (i.e., a silicon rod shaped like a rectangular body) is formed.
In the embodiment, as can be seen from the above, the silicon rod may form a boundary skin after being cut by the cutting device, and in order not to hinder the rising of the wire cutting device, the boundary skin needs to be timely unloaded, and for the unloading of the boundary skin, in most of the common boundary skin unloading methods, the boundary skin is still manually separated from the cut silicon rod by an operator and is removed from the silicon rod cutting device, which is not only inefficient, but also increases the risk of damage to the cut silicon rod due to collision between the boundary skin and the cut silicon rod during the transportation process. In view of the above, the silicon rod cutting and grinding all-in-one machine further includes a flaw-piece discharging device for discharging a flaw-piece formed after the silicon rod is subjected to the cutting by the wire cutting device, that is, in this embodiment, the first cutting unit further includes a first flaw-piece discharging device for discharging a flaw-piece formed after the silicon rod is subjected to the cutting by the first cutting unit in the first direction; the second cutting unit further comprises a second flaw-piece discharging device which is used for discharging flaw-pieces formed after the second cutting unit performs second-direction side cutting on the silicon rods.
Since the first and second flaw-piece discharging devices have the same structure, only the first flaw-piece discharging device will be described as an example.
Generally, the first flaw-piece discharging device can comprise a flaw-piece lifting mechanism for lifting the flaw-piece to enable the top end of the flaw-piece to protrude out of the cut silicon rod. The flaw-piece lifting mechanism comprises a jacking piece arranged on a first framework in the first cutting unit, the jacking piece can be driven by a telescopic part to move in a telescopic mode, and the jacking piece is controlled to move in a stretching mode and then supports the bottom of the flaw-piece to lift the flaw-piece.
In some embodiments, the jacking member includes an abutting plate and a supporting plate, the abutting plate extends upwards from the bottom of the supporting plate, further, the abutting plate may be an arc-shaped plate adapted to the arc-shaped surface of the flaw-piece, when the abutting plate abuts against the flaw-piece, the abutting plate can fully contact with the arc-shaped surface of the flaw-piece, the contact portion of the abutting plate and the flaw-piece is smooth, or a cushion pad is added to the inner surface of the abutting plate, which is in contact with the flaw-piece. The supporting plate is used for supporting the bottom of the side leather, and further the supporting plate can be an arched plate matched with the bottom surface of the side leather. In other embodiments, the chord edge of the arched plate as the bearing plate can be additionally provided with a convex block so as to increase the contact area with the bottom surface of the side skin.
In some embodiments, the telescopic member may be, for example, an air cylinder with a telescopic rod, wherein the telescopic rod may be connected to the support plate in the jacking member through a connecting structure, and the air cylinder may drive the telescopic rod to drive the jacking member to perform telescopic motion. Here, jacking piece does concertina movement include jacking piece's shrink motion with jacking piece's extension motion, wherein, jacking piece's shrink motion specifically indicates the cylinder drive the telescopic link shrink is in order to drive jacking piece is kept away from the boundary leather, jacking piece's extension motion specifically indicates the cylinder drive the telescopic link extends in order to drive jacking piece is close to the boundary leather. Of course, the aforementioned telescopic component may also adopt other implementation manners, for example, the telescopic component may also be, for example, a servo motor with a lead screw, the lead screw is connected to the jacking member, and the lead screw is driven by the servo motor to rotate so as to drive the jacking member to make telescopic motion, for example, the lead screw is driven to rotate forward to drive the jacking member to make contraction motion and drive the lead screw rotates reversely to drive the jacking member to make extension motion, or the lead screw is driven to rotate forward to drive the jacking member to make extension motion and drive the lead screw rotates reversely to drive the jacking member to make contraction motion. As to the specific structure of the first pelt discharging device and its implementation, reference can be made to patent publications such as CN 208148230U.
In practical application, in an initial state, the telescopic rod drives the jacking part to be in a contraction state, the first cutting unit is driven to descend along with the cutting support so that the first cutting line section in the first cutting unit cuts the silicon rod on the first processing position in the first direction until the first cutting line section penetrates through the silicon rod, the first direction side face of the silicon rod is cut and a flaw-piece is formed, at the moment, the flaw-piece lifting mechanism descends to the bottom along with the first bobbin, the cylinder drives the telescopic rod to extend so as to drive the jacking part to be close to the flaw-piece until a butting plate in the jacking part is in contact with the flaw-piece and is butted against the flaw-piece, subsequently, the first cutting unit is driven to ascend along with the cutting support, the flaw-piece lifting mechanism ascends along with the cutting support to drive the flaw-piece to generate ascending displacement relative to the silicon rod which is subjected to one-time cutting, so that the top end of the flaw-piece protrudes, when the top end of the flaw-piece meets the set conditions compared with the projecting part of the silicon rod, the cutting support can be controlled to stop rising, so that the top end of the flaw-piece can be used as a force application part for grabbing, the flaw-piece is grabbed and unloaded, then the air cylinder drives the telescopic rod to contract to drive the jacking piece to return to the initial state, and simultaneously the cutting support is controlled to drive the first cutting unit and the flaw-piece lifting mechanism to continuously rise above the silicon rod for executing next cutting operation.
In other embodiments, the lifting mechanism may include an absorbing member and a telescopic member for driving the absorbing member to perform telescopic movement, and the absorbing member is controlled by the telescopic member to abut against the hem and absorb the hem. The adsorption piece further comprises an abutting plate and an adsorption element. The abutting plate can be an arc-shaped plate matched with the arc-shaped surface of the edge leather, and can be fully contacted with the arc-shaped surface of the edge leather when the abutting plate abuts against the edge leather. The suction element may be, for example, a vacuum cup, and a plurality of vacuum cups may be arranged on a contact surface of the abutment plate to be in contact with the flaw-piece. The telescopic component can be, for example, an air cylinder with a telescopic rod or a servo motor with a screw rod, taking the air cylinder with a telescopic rod as an example, the telescopic rod can be connected with the abutting plate in the jacking piece through a connecting structure, the air cylinder can drive the telescopic rod to contract to drive the abutting plate to be away from the flaw-piece, and the air cylinder can drive the telescopic rod to extend to drive the abutting plate to be close to the flaw-piece and to be adsorbed to the flaw-piece by the adsorbing element after the abutting plate is contacted with the flaw-piece.

In this way, the first silicon rod 100 at the first processing location can be cut with the cutting device 2 in the embodiment shown in fig. 9.
When the first silicon rod 100 at the first processing location is cut by the cutting apparatus 2 in the embodiment shown in fig. 9, with reference to fig. 1, the cutting support 22 is driven to descend relative to the cutting frame 21, and the first silicon rod 100 at the first processing location is cut laterally in the X-axis direction by the first cutting unit 23 at one side of the cutting support 22 (the first cutting unit is provided with a first cutting wire net in a shape of a letter ═ in the X-axis direction).

Note that, before the second cutting unit 25 is used to cut the side surface of the first silicon rod 100 at the second processing location along the Y-axis direction, the silicon rod positioning mechanism 43 in the silicon rod conversion device 4 is further used to drive the first silicon rod 100 to rotate forward or backward by 90 ° to adjust the cutting surface due to the above-mentioned problem of side surface cutting. In this way, after the first silicon rod 100 located at the second processing location is cut along the side surface in the Y-axis direction by the second cutting unit 25, a silicon rod having a square shape as a whole is formed.

It should be noted that before the second silicon rod 102 at the second processing location is cut along the Y-axis direction by the second cutting unit 25, the silicon rod positioning mechanism 43 in the silicon rod conversion device 4 is further used to drive the second silicon rod 102 to rotate forward or backward by 90 ° to adjust the cutting surface due to the aforementioned problem of cutting along the Y-axis. In this way, after the second silicon rod 102 located at the second processing location is cut along the side surface in the Y-axis direction by the second cutting unit 25, a silicon rod having a square shape as a whole is formed.

Meanwhile, the second silicon rod 102 at the third processing location of the silicon rod processing platform may be ground by the grinding device 3 in the embodiment shown in fig. 12. For a specific manner of using the grinding device 3 to grind the second silicon rod 102 at the third processing position of the silicon rod processing platform, reference is made to the foregoing description, and no further description is given here.

Note that, before the second cutting unit 25 is used to cut the side surface of the third silicon rod 104 at the second processing location along the Y-axis direction, the silicon rod positioning mechanism 43 in the silicon rod conversion device 4 is further used to drive the third silicon rod 104 to rotate forward or backward by 90 ° to adjust the cutting surface due to the aforementioned problem of side surface cutting.

In step S203, the waiting location and the first processing location are 120 °, so that the first preset angle for rotating the silicon rod conversion device is to rotate the silicon rod conversion device forward by 120 °.
When the cutting device is used for cutting the second silicon rod on the first processing area of the silicon rod processing platform and the second silicon rod on the first processing area, the cutting support is driven to descend relative to the cutting frame, the first cutting unit and the second cutting unit on the left side and the right side of the cutting support simultaneously cut the second silicon rod on the corresponding first processing area and the first silicon rod on the second processing area, wherein the first cutting unit cuts the second silicon rod on the first processing area along the side face in the X-axis direction (the first cutting unit is provided with a first cutting wire net which is shaped like a Chinese character ═ in the X-axis direction), and the second cutting unit cuts the first silicon rod on the second processing area along the side face in the Y-axis direction (the second cutting unit 25 is provided with a second cutting wire net which is shaped like a Chinese character ═ in the Y-axis direction). Before the first silicon rod on the second processing position is cut along the side surface in the Y-axis direction by the second cutting unit, the silicon rod positioning mechanism in the silicon rod conversion device needs to be used for driving the first silicon rod to rotate forward or reversely by 90 degrees to adjust the cutting surface due to the problem of the side surface cutting.

The silicon rod conversion device is reversely rotated by 240 degrees, so that the silicon rod conversion device can return to the initial position, and a cable wound in the forward rotation process can be released.
