Description

Technical Field

[0001] The utility model relates to the technical field of hard and brittle material processing equipment, and specifically provides a grinding machine. Background Art

[0002] Equipment for processing hard and brittle materials usually includes cutting machines, squaring machines, grinders and slicers. Taking the workpiece of hard and brittle material as silicon rod as an example, the cutting machine is mainly used to cut longer silicon rods into shorter silicon rods (such as silicon rods with a circular cross-section, referred to as round rods) by methods such as wire cutting, the squarer is mainly used to cut round rods into silicon rods with a rectangular cross-section (such as a square) by methods such as wire cutting (referred to as square rods, if the square rods at this stage have not been ground, they can usually be called rough rods), the grinder is mainly used to make the surface accuracy of the rough rod meet the standard through grinding operations (such as the square rods at this stage meet the surface accuracy after grinding, and they can usually be called finished rods), and the slicer is mainly used to obtain thin silicon wafers for use from the finished rods through methods such as multi-wire cutting (wire mesh cutting).

[0003] Among them, the grinding machine mainly includes a horizontal grinder and a vertical grinder. For the horizontal grinder, its structure usually includes a loading / unloading device, a feed slide device and a grinding device. The process of grinding the silicon rod is usually as follows: first, the squared silicon rod (the aforementioned rough rod) is fixed to the loading device, and after the initial adjustment of the posture of the silicon rod, the silicon rod is delivered between the two chucks of the feed slide device, and the silicon rod is delivered to the position corresponding to the grinding device by the movement of the feed slide device along the axial direction (feed direction) of the silicon rod. Based on this, by bringing the grinding device close to the silicon rod and reciprocating the silicon rod along the feed direction, one group of surfaces to be ground or a pair of edges of the silicon rod can be subjected to corresponding grinding operations. Afterwards, by rotating the silicon rod, it is rotated to the second group of surfaces to be ground or another pair of edges, and so on, the rough rod can be processed into a finished rod by the grinder as described above.

[0004] It can be seen that the current horizontal grinder mainly relies on the reciprocating motion of the silicon rod along the feeding direction to complete its grinding operation. Since the reciprocating motion of the silicon rod requires a large moving stroke, the linear operation corresponding to the large moving stroke will have a certain impact on the accuracy of the silicon rod after grinding (such as the straightness of the linear guide matching the linear motion has a greater impact on the accuracy of the silicon rod). Such an impact will bring about a large grinding allowance, and the grinding accuracy of the silicon rod does not meet the standard. Therefore, those skilled in the art need a new solution to change or adjust the current grinding machine processing method. Utility Model Content

[0005] The utility model aims to provide a structure, which is matched with a grinding assembly to realize the form of a silicon rod being stationary while the grinding assembly reciprocates during the process of machining a workpiece by the grinding assembly.

For example, in the scenario of the present invention, the grinder is a horizontal grinder, and the silicon rod does not need to reciprocate in the horizontal grinding area, but the grinding assembly reciprocates along the axis of the silicon rod. In the case of adopting the jaw assembly of the present invention, the basic clamping of the silicon rod can be achieved by a pair of jaw assemblies, and the horizontal / vertical fine-tuning of the posture of the silicon rod can be achieved by adjusting the jaw assembly.

[0020] For the above-mentioned grinding machine, in a possible implementation, the unloading material storage table flip assembly can be movably unfolded to a first state so as to be spliced ​​with the unloading material storage table assembly and / or folded to a second state that does not affect the material storage performance of the unloading material storage table assembly.

[0024] In a third aspect, the utility model provides a grinding machine, which includes a transfer mechanism and a jaw assembly arranged on the transfer mechanism, and the jaw assembly includes: a first jaw assembly; and a second jaw assembly; wherein the first jaw assembly and the second jaw assembly are both capable of clamping a workpiece, and the first jaw assembly and the second jaw assembly can at least produce relative movement towards / away from each other.

[0025] With such a configuration, it is possible to reliably clamp the workpiece therebetween through the cooperation between the two jaw assemblies.

[0026] It is understandable that those skilled in the art can determine the structure, number, and specific manner of relative motion between the first / second clamping jaw assembly according to actual needs. For example, the manner in which the first / second clamping jaw assembly produces relative motion can be that one of the clamping jaw assemblies moves or both of the clamping jaw assemblies move.

[0027] In addition, in addition to meeting the basic clamping requirements, the posture of the clamped silicon rod (such as whether it is centered, tilted, etc.) can be adjusted through other forms of movement or motion.

[0028] For the above-mentioned grinder, in a possible implementation, the grinder also includes a transfer mechanism, the jaw assembly is arranged on the transfer mechanism, the first jaw assembly is a fixed jaw assembly that can be fixedly arranged on the transfer mechanism, and the second jaw assembly is an adjustable jaw assembly that can approach / move away from the fixed jaw assembly.

[0029] Through such a configuration, a specific structural form is provided for the first / second clamping jaw assembly to realize relative movement between the two. For example, by adjusting whether the fixed clamping jaw assembly is fixed to the transport mechanism, relative movement between the two can be realized in different ways.

[0030] It is understandable that those skilled in the art can determine the specific driving transmission method for adjusting the jaw assembly to achieve its movement towards / away from the fixed jaw assembly according to actual needs, such as through a gear pair, a screw nut pair, a belt drive, etc.

[0031] It is understandable that those skilled in the art can determine the structural form and number of the transfer mechanism, the mode of cooperation between the transfer mechanism and the clamping assembly, and the direction range in which the position of the clamping assembly can be changed, etc., according to actual needs. For example, the transfer mechanism can drive the silicon rod clamped in the clamping assembly to cause displacement along the length direction, etc.

[0032] For the above-mentioned grinding machine, in a possible implementation manner, the grinding machine includes a switching assembly, and the fixed jaw assembly can be fixedly disposed on the transfer mechanism or can perform relative movement with the transfer mechanism by means of the switching assembly.

[0033] This configuration provides a possible movement mode for the fixed jaw assembly to be arranged on the transport mechanism. In this way, the fixed jaw assembly can be fixedly arranged on the transport mechanism or movably arranged on the transport mechanism by switching the switching assembly, such as a movement similar to the movement form and direction of the adjustment jaw assembly or a movement that is partially different from or relatively independent of the adjustment jaw assembly.

[0034] For the above-mentioned grinding machine, in a possible embodiment, the jaw assembly includes a jaw base and a jaw lateral movement mechanism arranged on the jaw base, and the jaw lateral movement mechanism can drive the adjustment jaw assembly to move closer to / away from the fixed jaw assembly, wherein the switching assembly can make the jaw lateral movement mechanism drive connected to the fixed jaw assembly and thereby drive the jaw lateral movement mechanism to move, or release the driving connection between the jaw lateral movement mechanism and the fixed jaw assembly and thereby fix the fixed jaw assembly to the jaw base.

[0035] Through such a configuration, a possible way of fixing the clamping jaw assembly and adjusting the clamping jaw member to form the clamping jaw assembly is provided.

[0036] It is understandable that those skilled in the art can determine the specific form of the clamping jaw transverse movement mechanism to achieve its drive connection and the specific drive transmission form corresponding thereto according to actual needs. For example, the clamping jaw transverse movement mechanism can be directly driven and connected to the adjustment clamping jaw assembly through a power cylinder or the like, or driven and connected to the adjustment clamping jaw assembly through an intermediate transmission mechanism, such as a belt drive, a chain drive, a gear drive, etc.

[0037] Furthermore, it is understandable that those skilled in the art can determine the specific way to establish or release the constraint between the switching assembly and the clamping jaw lateral movement mechanism according to actual needs. For example, the clamping jaw lateral movement mechanism includes a power cylinder, and the switching assembly can drive the power output end of the power cylinder to connect or disconnect with the fixed clamping jaw assembly.

[0038] For the above-mentioned grinding machine, in a possible embodiment, the jaw lateral movement mechanism includes a jaw lateral movement transmission structure, and the jaw lateral movement transmission structure has a first mounting position and a second mounting position along its conveying direction, the fixed jaw assembly can be set at the first mounting position, and the adjustable jaw assembly is set at the second mounting position.

[0039] With such a configuration, it is possible to fix or move the fixed jaw assembly by adjusting the restraint relationship between the fixed jaw assembly and the first mounting position.

[0040] It is understandable that those skilled in the art can determine the specific forms of the clamping jaw lateral movement transmission structure, the first / second installation position, etc. and the specific implementation method of fixing / adjusting the clamping jaw assembly to the first / second installation position, etc. according to actual needs. For example, the clamping jaw lateral movement transmission structure can be a conveyor belt, a conveyor chain, etc., and the first / second installation position can be a mounting table, a mounting slot, a mounting seat, etc.

[0041] For the above-mentioned grinding machine, in a possible implementation, the switching assembly includes a switching drive component and a switching component, and the switching drive component can drive the switching component to change state and establish or release constraints between the transverse movement transmission structure of the clamping jaw and the fixed clamping jaw assembly.

[0042] Through such a configuration, a possible structural form of the switching component is provided.

[0043] It is understandable that those skilled in the art can determine the structural form of the switching component and the state switching mode under the driving of the switching driving component and the specific implementation mode of establishing / releasing the constraint with the fixed jaw assembly according to the actual situation. For example, the switching component can be a plate-like structure, a rod-like structure, etc., which can change its state through movement modes such as extension and rotation under the driving of the switching driving component.

[0044] For the above-mentioned grinding machine, in a possible implementation manner, the switching component is a clamping structure, and the switching driving component can drive the clamping structure to extend and cause the clamping jaw to move laterally to establish a constraint between the transmission structure and the fixed clamping jaw assembly.

[0045] Through such a configuration, a possible structural form of the switching structure is provided.

[0046] For the above-mentioned grinding machine, in a possible embodiment, the switching assembly includes a reset structure so that: when the constraint between the lateral movement transmission structure of the clamp and the fixed clamp assembly is released, the fixed clamp assembly is in the set position of the transfer mechanism with the help of the reset structure.

[0047] With such a configuration, it is possible to ensure the position reliability of the fixed jaw assembly when its position is relatively fixed, and thus ensure the reliability of clamping the workpiece when it and the adjustable jaw assembly form a jaw assembly.

[0048] In a possible implementation manner, the reset structure is a reset spring and / or the clamping jaw lateral movement transmission structure is a transmission chain.

[0049] Through such a structure, a specific form of the clamping jaw lateral movement transmission structure is provided.

[0050] For the above-mentioned grinding machine, in a possible implementation manner, the fixed jaw assembly includes: a first fixed jaw; and a second fixed jaw; the first fixed jaw and the second fixed jaw can move relative to each other in a manner of approaching or moving away from each other.

[0051] Through such a configuration, a possible structural form of the fixed clamping jaw assembly is provided.

[0052] For the above-mentioned grinding machine, in a possible implementation manner, the fixed jaw assembly includes a fixed jaw driving component, and the fixed jaw driving component can drive the first fixed jaw and the second fixed jaw to move toward / away from each other in a synchronous manner.

[0053] Through such a configuration, a possible implementation method of clamping or releasing a workpiece by a fixed jaw assembly is provided. For example, the fixed jaw driving component can directly drive (for example, the fixed jaw driving component is a power cylinder, a linear module, etc.) or indirectly drive the first / second fixed jaw to move through a transmission mechanism such as a gear rack pair. Exemplarily, the first fixed jaw and the second fixed jaw are respectively equipped with a drive motor, and the drive motor is connected to the corresponding first / second fixed jaw through a gear rack pair.

[0054] For the above-mentioned grinding machine, in a possible implementation manner, the fixed jaw assembly includes a fixed jaw screw nut mechanism, and the fixed jaw driving component drives the first fixed jaw and the second fixed jaw to move synchronously toward / away from each other through the fixed jaw screw nut mechanism.

[0055] Through such a configuration, a specific structural form of the fixed clamping jaw assembly is provided. For example, two sections of threads corresponding to the first / second fixed clamping jaws are arranged on the lead screw, and the rotation directions of the two sections of threads are opposite.

[0056] For the above-mentioned grinding machine, in a possible implementation manner, the adjustment jaw assembly includes: a first adjustment jaw; and a second adjustment jaw; the first adjustment jaw and the second adjustment jaw can at least generate movement towards / away from each other in a relatively independent manner.

[0057] Through such a structure, a possible structure of the adjusting jaw assembly is provided. For example, the first adjusting jaw and the second adjusting jaw can use the same or different driving transmission mechanisms to realize the movement of the two.

[0058] For the above-mentioned grinding machine, in a possible implementation manner, the adjusting jaw assembly includes a first adjusting jaw driving component, and the first adjusting jaw driving component can drive one of the first adjusting jaw and the second adjusting jaw corresponding thereto to move closer to / away from the other.

[0059] Through such a configuration, a possible implementation method of clamping or releasing the workpiece by the adjusting jaw assembly is provided. Similar to the aforementioned fixed jaw driving component, the first adjusting jaw driving component can directly drive (such as the first adjusting jaw driving component is a power cylinder, a linear module, etc.) or indirectly drive the first / second adjusting jaw to move through a transmission mechanism such as a screw nut pair. Exemplarily, the first adjusting jaw and the second adjusting jaw are respectively equipped with a drive motor, and the drive motor is connected to the corresponding first / second fixed jaw drive through a screw nut pair.

[0060] In addition, since the two adjustment jaws in the adjustment jaw assembly can move relatively independently in the direction of approaching / moving away from each other, the lateral position of the workpiece can also be finely adjusted. For example, after the workpiece is clamped, the two adjustment jaws are moved synchronously in the same direction, or before the workpiece is clamped, the two adjustment jaws are moved in different directions, amplitudes, and occurrence times.

[0061] For the above-mentioned grinding machine, in a possible embodiment, the adjusting jaw assembly includes a first adjusting gear rack pair, and the first adjusting jaw driving component can drive one of the first adjusting jaw and the second adjusting jaw corresponding to the first adjusting gear rack pair through the first adjusting gear rack pair to produce movement closer to / away from the other.

[0062] Through such a configuration, a specific structural form of the adjusting jaw assembly is provided.

[0063] For the above-mentioned grinding machine, in a possible implementation manner, the adjustment jaw assembly includes a first adjustment guide structure, and the first adjustment jaw and the second adjustment jaw can move along the first adjustment guide structure.

[0064] By such a configuration, the reliability of the first / second adjustment jaws during the lateral movement can be ensured. For example, the first adjustment guide structure can be a guide rail, a guide groove, a guide shaft, and the like.

[0065] For the above-mentioned grinding machine, in a possible implementation manner, the adjusting jaw assembly includes a second adjusting jaw driving component, and the second adjusting jaw driving component can drive the first adjusting jaw and the second adjusting jaw to generate movement in a vertical direction.

[0066] With such a configuration, it is possible to change the local position of the workpiece by vertical fine adjustment on the side of the adjusting jaw assembly, and thereby adjust the posture to be processed so that its accuracy meets the grinding standard.

[0067] It is understandable that those skilled in the art can determine the structural form and number of the second adjustment jaw driving component, the corresponding relationship between the second adjustment jaw and the first / second adjustment jaw, and the specific method of driving the first / second adjustment jaw to produce vertical movement according to actual needs. For example, the first / second adjustment jaw is respectively equipped with a driving motor, and the driving motor drives the corresponding first / second adjustment jaw to produce lifting movement through a gear rack pair; the first / second adjustment jaw is equipped with the same power cylinder, and the first / second adjustment jaw is both arranged on a carrier such as a support platform, and the power cylinder is connected to the support platform by driving; etc.

[0068] For the above-mentioned grinding machine, in a possible implementation manner, the adjusting jaw assembly includes an eccentric structure, and the second adjusting jaw driving component drives the first adjusting jaw and the second adjusting jaw to move in a vertical direction through the eccentric structure.

[0069] Through such a structure, a possible implementation method for the first / second adjusting clamping jaw to realize its lifting movement is provided, such as the eccentric structure can be an eccentric shaft, a cam, etc.

[0070] For the above-mentioned grinding machine, in a possible embodiment, the adjusting jaw assembly includes an adjusting jaw base, the adjusting jaw base includes a movable part, and the movable part has a reserved space. The eccentric structure can cooperate with the reserved space and thereby cause the first adjusting jaw and the second adjusting jaw to move in a vertical direction.

[0071] Through such a configuration, a possible structural form of the adjusting jaw assembly and a possible way of realizing the transmission of the corresponding eccentric structure are provided. For example, the movable part can be a plate-shaped structure, a block-shaped structure, a cylindrical structure, a bracket, etc.

[0072] For the above-mentioned grinding machine, in a possible implementation manner, the adjusting jaw base includes a fixed portion, and the second adjusting jaw driving component is disposed on the fixed portion.

[0073] Through such a configuration, a specific structural form of the adjustment jaw assembly is provided. Similar to the movable part, the fixed part may be a plate-like structure, a block-like structure, a cylindrical structure, a bracket, etc.

[0074] For the above-mentioned grinding machine, in a possible implementation manner, the adjustment jaw assembly includes a second adjustment guide structure, and the movable part and the first adjustment jaw and the second adjustment jaw disposed on the movable part are capable of moving along the second adjustment guide structure.

[0075] By such a structure, the reliability of the first / second adjustment jaw during the longitudinal movement can be ensured. For example, the second adjustment guide structure can be a guide rail, a guide groove, a guide shaft, etc. For example, the first adjustment jaw and the second adjustment jaw are arranged on the movable part through the aforementioned first adjustment gear rack pair and the first adjustment guide structure.

[0076] For the above-mentioned grinding machine, in a possible implementation manner, the eccentric structure is a cam.

[0077] Through such a construction, a specific structural form of the eccentric structure is provided.

[0078] For the above-mentioned grinding machine, in a possible embodiment, the transfer mechanism includes: a first moving component, with the aid of which the clamping assembly can move in a horizontal direction; and / or a second moving component, with the aid of which the clamping assembly can move in a vertical direction.

[0079] It is understandable that those skilled in the art can determine the specific form of the first / second moving assembly and the specific way in which the corresponding movement is realized according to actual needs. Taking the first moving assembly as an example, it can be: a power cylinder, a linear module, etc. are directly connected to the clamping assembly by driving; a motor, etc. are indirectly connected to the clamping assembly by driving through a gear rack pair, a screw nut mechanism, etc.; etc.

[0080] In a second aspect, the utility model provides a grinding machine, which is a horizontal grinder, comprising: a clamping assembly, which includes a first chuck and a second chuck, and a workpiece can be clamped between the first chuck and the second chuck; and a grinding assembly, which can move radially toward / away from the workpiece; the horizontal grinder also includes: a slide mechanism, and the grinding assembly is slidably arranged on the slide mechanism, so that: when the workpiece is clamped by the clamping assembly, the workpiece is ground by the grinding assembly moving along the axial direction of the workpiece on the slide mechanism.

[0081] With such a structure, it is possible to complete the grinding operation by keeping the workpiece (such as a silicon rod) stationary and the grinding assembly moving. Since the movement of the workpiece often requires a large space to be reserved, such an operation method can significantly save the space corresponding to the grinding area. In addition, since the workpiece is in a relatively static state during the grinding operation, the position accuracy of the workpiece in the clamping state can be better guaranteed, and on this basis, the grinding accuracy of the workpiece can be effectively guaranteed.

[0082] It is understandable that those skilled in the art can determine the structural form of the first / second chuck according to actual needs. For example, the first / second chuck can be rotated synchronously to realize the switching of different grinding positions of the workpiece, and the first / second chuck can be moved relative to each other to clamp the workpiece, such as one of the first / second chuck is a movable chuck and the other is a fixed chuck, or both the first / second chuck are movable chucks.

[0083] It is understandable that those skilled in the art can determine the structural form, number of the slide mechanism and the specific form of sliding connection with the grinding assembly according to actual needs, such as including but not limited to: the slide mechanism has a guide rail that cooperates with the grinding assembly, and the drive motor is connected to the grinding assembly through a screw nut mechanism, a gear rack mechanism, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0180] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0182] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0183] In addition, in order to better illustrate the present invention, many specific details are given in the following specific embodiments, and those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, the principles of grinding machines, etc., which are well known to those skilled in the art, are not described in detail in order to highlight the main purpose of the present invention.

[0184] In a possible embodiment, the grinding machine of the utility model includes a grinding device 1 and a transfer mechanism 2, wherein the grinding device 1 mainly includes a loading component 11, a unloading component 12 and a grinding component 13, and the transfer mechanism 2 mainly includes a support component, a moving component and a clamping component 23. In this example, the support component includes a gantry component, such as the gantry component includes a basic support part 211 and two gantries 212 arranged on the basic support part, the moving component includes a transverse moving component 221 capable of moving along the length direction of the gantry and a longitudinal moving component 222 capable of moving along the vertical direction, and a clamping component is arranged on the moving component. When the workpiece is clamped in the clamping component (the clamping component holds the workpiece), the rough rod can be transferred from the loading device to the grinding device and the finished rod can be transferred from the grinding device to the unloading device through the moving component.

[0185]

Horizontal movement component

[0186] In a possible implementation, the lateral movement assembly 221 includes a lateral movement drive motor 2211, a lateral movement lead screw nut mechanism, and a lateral movement linear guide rail. For example, one of the two gantry frames is equipped with a drive motor (and a lead screw nut mechanism, a lateral movement linear guide rail, etc.) and is therefore called a main frame, while the other is not equipped with a drive mechanism (including a lateral movement linear guide rail, etc.) and is therefore called a secondary frame.

[0187] In a possible implementation, the basic support part 211 includes a gantry column and a gantry frame arranged on the gantry column, a main frame and a sub-frame are arranged on the gantry frame, and a reinforcing structure such as a connecting rib 213 is also arranged between the main frame and the sub-frame to make the structure of the gantry assembly more stable. The gantry assembly is mainly used to support the transfer mechanism as a transfer device.

[0188] In a possible implementation, the moving assembly includes a slide 223, the clamping assembly 23 is arranged on the slide, and the lateral movement driving motor drives the slide to move on the lateral movement linear guide through the lateral movement screw nut mechanism, so that the slide drives the clamping assembly to move along the lateral movement linear guide of the gantry. In this way, the precise movement of the slide in the lateral movement direction can be achieved through the servo control of the lateral movement driving motor. For example, limit detection switches can be respectively arranged on both sides of the slide along its lateral movement direction to ensure that the slide can accurately move within its effective stroke.

[0189]

Vertical movement components

[0190] In a possible embodiment, the longitudinal movement assembly 222 includes a longitudinal movement slide 2221 (arranged between the main frame and the auxiliary frame), a longitudinal movement drive motor 2222 and a longitudinal movement rack and pinion pair 2223. If the longitudinal movement rack and pinion pair includes a longitudinal movement gear connected to the longitudinal movement drive motor and a longitudinal movement rack arranged on the longitudinal movement slide, the longitudinal movement drive motor is arranged on the slide and thus enables the slide to move in the vertical direction on the longitudinal movement slide. Based on this, the longitudinal movement drive motor can be synchronized with the slide on the longitudinal movement slide by means of the longitudinal movement rack and pinion pair to achieve longitudinal movement. In this way, the servo control of the longitudinal movement drive motor can be used to achieve precise movement of the slide in the longitudinal movement direction. By transmitting the power from the longitudinal movement drive motor through the meshing of the gear and the rack, the layout space of the longitudinal movement assembly including the longitudinal movement rack and pinion pair can be effectively saved.

[0191] In a possible implementation, a longitudinal moving linear guide 2224 is also provided on the longitudinal moving slide to ensure the stability of the moving process. For example, a longitudinal moving linear guide is provided at each position close to the four edges of the longitudinal moving slide, so there are four longitudinal moving linear guides in total, so that the slide can obtain better stability when moving along the longitudinal moving direction, such as the four longitudinal moving linear guides are located on three of the four side surfaces of the longitudinal moving slide to prevent over-positioning. Exemplarily, the aforementioned longitudinal moving rack is fixedly provided between two longitudinal moving linear guides.

[0192] In a possible implementation, a longitudinal movement drive motor installation component 2231 is provided on the slide, such as the longitudinal movement drive motor installation component being an annular shell that can be sleeved on the outer side of the aforementioned longitudinal movement slide, such as the inner side of the annular shell being provided with guide grooves that can cooperate with the aforementioned two pairs of longitudinal movement linear guide rails, and the longitudinal movement drive motor being provided on the longitudinal movement drive motor installation frame. For example, the annular shell includes a vertical portion and a transverse portion extending outward from the bottom of the vertical portion, such as the transverse portion being fixed to the top of the slide by means of fasteners such as screws, and in order to ensure the strength of the annular shell, a reinforcing structure such as a reinforcing plate can be added between the vertical portion and the transverse portion.

[0193]

Gripper assembly

[0194] In a possible implementation, the main functions of the clamping jaw assembly 23 include:

[0195] 1) The silicon rod can be clamped in two postures. For example, in this example, the clamping jaw assembly can perform V-shaped clamping at a 45° surface and conventional clamping at a 0° surface on the silicon rod.

[0196] 2) The switching assembly can realize single movement of the adjusting jaw assembly (the fixed jaw assembly is in the first state) and linkage between the fixed jaw assembly and the adjusting jaw assembly (the fixed jaw assembly is in the second state).

[0197] 3) By adjusting the clamping jaw assembly, the central axis of the silicon rod can be fine-tuned to better adapt to the silicon rod (rough rod) from the feeding assembly side, or to compensate for the incoming deviation of the rough rod.

[0198] 4) Grabbing the material at a 45° angle from the loading assembly can better achieve center alignment of the silicon rod.

[0199] In a possible implementation, the clamping jaw assembly 23 mainly includes a clamping jaw base (such as a fixed seat, etc.) 230, and a fixed clamping jaw assembly 231 and an adjustable clamping jaw assembly 232 arranged on the clamping jaw base, and the fixed clamping jaw assembly and the adjustable clamping jaw assembly can cooperate to form a clamping space for clamping a silicon rod. Among them, a clamping jaw lateral movement mechanism 233 is arranged on the clamping jaw base, and the fixed clamping jaw assembly and the adjustable clamping jaw assembly can generate relative movement towards / away from each other by means of the clamping jaw lateral movement mechanism.

[0200] In a possible embodiment, the clamping jaw lateral movement mechanism 233 includes a clamping jaw lateral movement drive motor 2331 and a gear chain pair 2332. The clamping jaw lateral movement drive motor is connected to the gear of the gear chain pair to drive the chain meshing with the gear to move along its axis. The chain is provided with a first mounting position 23331 and a second mounting position 23332 along its axis. The fixed clamping jaw assembly can be provided at the first mounting position, and the adjustable clamping jaw assembly is fixedly provided at the second mounting position and can therefore move with the movement of the chain. Exemplarily, the first / second mounting position is a mounting seat fixed to the chain.

[0201] In a possible embodiment, the jaw lateral movement mechanism is provided with a set of switching components 2334 at a position corresponding to the first installation position. When the fixed jaw assembly needs to move with the adjusting jaw assembly, the fixed jaw assembly is switched to the first state with the help of the switching component, specifically, the fixed jaw assembly is fixed to the state of the first installation position. When the fixed jaw assembly does not need to move with the adjusting jaw assembly, the fixed jaw assembly is switched to the second state with the help of the switching component, specifically, the state in which the fixed constraint relationship between the fixed jaw assembly and the first installation position is released. In this way, through the cooperation of the switching component, the fixed jaw assembly can switch between the first state and the second state. Based on this, it is expected that the fixed jaw assembly and the adjusting jaw assembly can better meet the needs of silicon rods during transportation.

[0202] In a possible embodiment, the switching assembly 2334 includes a cylinder 23341 as a switching drive component, and the power output end of the cylinder is connected to a clamping block 23342. In this way, when the power output end of the cylinder is pushed downward, the clamping block can be pushed downward to make the clamping block abut against the first installation position or the fixed jaw assembly set on the first installation position, so that the fixed jaw assembly is locked with the chain. In this way, the fixed jaw assembly and the adjustment jaw assembly can move together with the movement of the chain. Correspondingly, when the position of the fixed jaw assembly needs to be relatively fixed, the clamping block is separated from the first installation position or the fixed jaw assembly set on the first installation position by retracting the power output end of the cylinder upward. If the switching assembly includes a mounting frame 23343, the cylinder, the clamping block and the fixed jaw assembly are all arranged on the mounting frame, and a reset structure such as a reset spring 23344 is arranged between the mounting frame and the transfer mechanism. After separation, the fixed jaw assembly and other structures arranged on the mounting frame can return to the position set by the transfer mechanism under the action of the reset spring. For example, the reset structure may also be other structural forms such as a power cylinder, a linear module including a motor, etc. that can provide pulling force along a set direction.

[0203] It is understandable that the above structure is only one exemplary description of the switching component, and those skilled in the art can determine the structural form, the first state, the second state, and the switching method between the two of the switching component according to actual needs. For example, the constraint relationship between the clamping block and the first mounting position can be changed from abutment to other matching relationships such as plug-in, meshing, and mortise and tenon, and the switching drive component can be changed from a cylinder to other power cylinders such as a hydraulic cylinder, an electric cylinder, or a linear module with equivalent functions. In addition to the above-mentioned cylinder and clamping block assembly, any form of clutch device can be reasonably modified to serve as the switching component of the utility model.

[0204]

Fixed jaw assembly

[0205] In a possible implementation, the fixed jaw assembly mainly includes a fixed jaw base 2311 (such as a connecting seat, etc.), a fixed jaw drive motor 2312, a fixed jaw lead screw nut mechanism 2313 and a fixed jaw group. The fixed jaw group includes a first fixed jaw 23141 and a second fixed jaw 23142, such as a fixed jaw base that is roughly a U-shaped connecting seat, a lead screw of the fixed jaw lead screw nut mechanism is arranged between two vertical parts of the connecting seat, a fixed jaw drive motor is arranged on a transverse part of the connecting seat, and two sections of thread segments with opposite rotation directions are arranged on the lead screw of the fixed jaw lead screw nut mechanism, and the first fixed jaw and the second fixed jaw are respectively fixed to two nuts of the fixed jaw lead screw nut mechanism that match the two thread segments. Based on this, by driving the lead screw in the fixed jaw lead screw nut mechanism to rotate through the fixed jaw drive motor, the (first and second) fixed jaws can simultaneously move in a direction close to / away from each other, thereby completing the centering clamping function of the silicon rod. In addition, while the material is clamped by the fixed jaw drive motor, the cross-sectional dimensions of the silicon rod can also be directly calculated based on this, saving the time of the material loading and transportation process.

[0206] It is understandable that the fixed jaw drive motor and the fixed jaw lead screw nut mechanism are only an exemplary description of realizing the relative movement between the first / second fixed jaws, and those skilled in the art can reasonably select them according to actual needs. For example, if the drive transmission form remains unchanged, the fixed jaw drive motor can be changed to a rotating module that can realize movement, the fixed jaw lead screw nut mechanism can be changed to a gear rack pair, and a set of fixed jaw lead screw nut mechanisms can be configured for each of the two fixed jaws (the two fixed jaws can move relatively independently), etc. In the case of adjusting the drive transmission form, the fixed jaw drive motor can be changed to a power cylinder (cylinder, electric cylinder, hydraulic cylinder, etc.) and other linear modules, etc., and the fixed jaw lead screw nut mechanism can be correspondingly changed to other component forms that can realize corresponding transmission, etc.

[0207] In a possible embodiment, the first fixed clamping jaw and the second fixed clamping jaw have a first clamping position 23151 and a second clamping position 23152 on the clamping parts facing each other, so that a first clamping space can be formed between the two through a pair of first clamping positions and a second clamping space can be formed through a pair of second clamping positions, wherein the first clamping space can clamp the silicon rod with a 45° surface (first posture, V-type clamping, or inclined clamping), and the second clamping space can clamp the silicon rod with a 0° surface (second posture, vertical clamping, or 0° conventional clamping). In this way, the clamping of silicon rods in two postures can be achieved by the same set of fixed clamping jaw assemblies. In this example, the first clamping space is mainly used to clamp the silicon rod (finished rod) after grinding operation by V-type clamping, and the second clamping space is mainly used to clamp the silicon rod (rough rod) before grinding operation by vertical clamping, and the first clamping space is located below the second clamping space.

[0208] For example, when vertical clamping is required, the two fixed jaws are moved close to each other until they are in close contact with the side of the silicon rod to clamp the silicon rod. For the same specification (size), when V-shaped clamping is required, the two fixed jaws need to be further moved close to each other so that the silicon rod can be clamped in a V-shaped clamping manner. Compared with the vertical clamping method, the V-shaped clamping method can achieve the coincidence of the diagonal of the silicon rod with the center of the first clamping space. Therefore, in the case of V-shaped clamping, the centering operation of the silicon rod can be completed simultaneously during the clamping process. In addition, based on the opening and closing distance between the two fixed jaws, the cross-sectional dimensions of the silicon rod can be accurately calculated.

[0209] In one possible embodiment, the fixed clamping jaw assembly also includes an anti-falling assembly 2316. The reason for adding the anti-falling assembly is that when the fixed clamping jaw assembly is clamping the silicon rod at a 0° surface, the clamping stability of the silicon rod is ensured by the friction between a pair of clamping fitting surfaces corresponding to the second clamping space and a pair of side surfaces of the silicon rod. Since the surface of the silicon rod after grinding is very smooth (the friction coefficient is very small), if the friction between the clamping fitting surface and the side surface of the silicon rod is insufficient, there may be a risk of slipping or even dragging the rod.

[0210] In a possible implementation, referring to the orientation relationship in which the first clamping space is located below the second clamping space in this example, an anti-falling assembly can be configured near the bottom of the two fixed clamping jaws. In this way, when the silicon rod is clamped in a vertical clamping manner, the anti-falling assembly can provide a certain auxiliary supporting force for the silicon rod, so that the silicon rod can be reliably clamped in the second clamping space. For example, the anti-falling assembly can be used to support the clamping reliability of the clamping jaw assembly during the period of clamping the silicon rod in a vertical clamping manner.

[0211] In a possible embodiment, the anti-falling assembly includes a pair of anti-falling hooks 23161 that are pivotally arranged corresponding to a pair of fixed clamping claws. When the silicon rod is clamped in a vertical clamping manner, the anti-falling hook can be rotated to provide a certain auxiliary pressing force and / or supporting force. Exemplarily, the anti-falling hook includes a first hook portion and a second hook portion that are arranged at an angle, and the intersection of the first hook portion 231611 and the second hook portion 231612 is pivotally connected to the corresponding first fixed claw or the second fixed claw. In this way, when the silicon rod is clamped in a vertical clamping manner, the anti-falling hook is rotated relative to the corresponding first fixed claw or the second fixed claw to such a state that the end of the first hook portion abuts against the side wall of the silicon rod, and the chamfered surface between the bottom surface and the side surface of the rod material (the narrow surface formed after the edge is chamfered) abuts against the wall of the second hook portion (hooking the bottom of the silicon rod through the second hook portion). Through such double protection (increasing the clamping force on the side and increasing the supporting force on the bottom), the clamping stability of the silicon rod can be effectively guaranteed, so that in the process of fixing the clamping jaw assembly to grab the silicon rod and other operations, the reliability and safety of the operation can be effectively guaranteed.

[0212] Since the silicon rod clamped at this time is a finished rod with surface accuracy that has been ground, a buffer structure such as a polyurethane layer can be provided at least at the end of the first hook and the side of the second hook to prevent the side and chamfered surface of the finished rod from being scratched.

[0213] Obviously, the structural form, number and pivot setting method of the above-mentioned anti-fall hook are only an exemplary description. Those skilled in the art can flexibly change them according to actual needs, such as: the end of the first hook has a multi-claw structure (similar to an octopus) or a deformable structure (such as silicone, etc.) to better achieve its abutment with the silicon rod; the side of the second hook is concave outward and the end has a structure similar to the first hook, so that the supporting force can be provided by double-end support; only the first hook or the second hook is included; the first hook and / or the second hook include multiple ones; the angle between the first hook and the second hook can be fixed or adjusted; the anti-fall hook can be pivotally set to the fixed claw, and can also be set at any reasonable position that can achieve the rotation of the anti-fall hook without interference and does not interfere with the movement of other parts.

[0214] In addition, a pair of rotatable anti-falling hooks is only an exemplary description of the anti-falling component. Technical personnel in this field can choose any reasonable structural form according to actual needs to ensure the clamping stability of the second clamping space, such as providing an abutment structure that can telescopically move along the clamping direction on the two clamping surfaces of the second clamping space, and providing a tightening structure on the outside that can provide an upward supporting force for the silicon rod.

[0215] In addition, although in this example the anti-falling component plays an auxiliary role only when the second clamping space is in the working state, it is obvious that the anti-falling component can also provide a certain auxiliary role when the first clamping space is in the working state.

[0216] [Adjusting the jaw assembly]

[0217] In a possible implementation, the adjusting jaw assembly 232 mainly includes an adjusting jaw base 232 (such as a connecting seat, etc.) and an adjusting jaw group disposed on the adjusting jaw base. The adjusting jaw group includes a first adjusting jaw 23221 and a second adjusting jaw 23222. In this example, the first / second adjusting jaws are similar in structure and function to the aforementioned first / second fixed jaws, and mainly form a first clamping space and a second clamping space through the cooperation between a pair of jaws and complete V-shaped clamping and vertical clamping of the silicon rod.

[0218] Different from the aforementioned fixed jaw group, the adjustment jaw group also includes a first adjustment component (lateral clamping, lateral fine-tuning) for realizing relative movement between the two adjustment jaws and a second adjustment component (longitudinal fine-tuning) for realizing movement of the two adjustment jaws in the vertical direction.

[0219] In one possible embodiment, the two adjustment jaws in the adjustment jaw assembly are respectively configured with a set of first adjustment components so that the two can realize their movement along the clamping direction in a relatively independent manner, that is, the first adjustment jaw and the second adjustment jaw can realize the movement towards / away from each other in a relatively independent manner. Taking the goal of achieving the approach between the first adjustment jaw and the second adjustment jaw as an example, the two can be approached in a manner such as both moving and approaching synchronously, both moving but approaching asynchronously, one being stationary while the other moving, etc.

[0220] In a possible embodiment, the structure of the first adjustment assembly corresponding to the first / second adjustment clamp is substantially the same and in this example, the first adjustment assembly includes a first adjustment drive motor 23231 and a first adjustment gear rack pair 23232, wherein the adjustment clamp base 2321 includes a fixed bracket body 23211 as a fixed part and a connecting bracket 23212 as a movable part, exemplarily, the bracket body is substantially an L-shaped structure, the connecting bracket is substantially a connecting plate parallel to the vertical part of the bracket body, the first adjustment drive motor is fixedly arranged on the bracket body of the adjustment clamp base, the power output end of the first adjustment drive motor is drivingly connected to the gear of the first adjustment gear rack pair, the rack of the first adjustment gear rack pair is fixedly connected to the first / second adjustment clamp, such as the first / second adjustment clamp includes a mounting plate and a claw portion arranged on the mounting plate, and the rack is arranged on the mounting plate. In this way, under the driving force of the first adjustment drive motor, the corresponding first / second adjustment clamp can be driven to move (transversely) through the transmission of the first adjustment gear rack pair.

[0221] For example, in order to ensure the reliability of the transverse movement of the first / second adjustment clamping jaws, a first adjustment linear guide rail 23233 may be provided on the connection bracket of the adjustment clamping jaw base, and the first / second adjustment clamping jaws can approach / move away from each other along the first adjustment linear guide rail under the driving transmission of the first adjustment assembly. Exemplarily, the first / second adjustment clamping jaws share a first adjustment linear guide rail, and accordingly, a groove structure matching the first adjustment linear guide rail is provided on the mounting plate.

[0222] In this way, the first adjustment jaw and the second adjustment jaw can respectively realize the centering clamping of the silicon rod through their respective first adjustment components. Since the two first adjustment components can move relatively independently, the lateral fine-tuning of the entire silicon rod can be realized with the help of a pair of first adjustment components after clamping the silicon rod, that is, the first adjustment component can realize the lateral movement corresponding to the silicon rod clamping operation and the lateral fine-tuning corresponding to the axis position of the silicon rod. (The longitudinal movement corresponding to the silicon rod feeding / retracting operation is realized by the aforementioned longitudinal movement component, and the longitudinal fine-tuning corresponding to the axis position of the silicon rod is realized by the second adjustment component). Specifically, if the central axis of the silicon rod is offset in the horizontal direction when it is clamped, the two first adjustment component drive motors can be used to drive the first / second adjustment jaws to move synchronously in the direction that can suppress the offset, so that the horizontal position accuracy of the silicon rod can be guaranteed.

[0223] It is understandable that the structural form of the aforementioned first adjustment assembly is only an exemplary description, and those skilled in the art can flexibly change it according to actual needs. For example, the structures of the two first adjustment assemblies can be partially or completely different, such as a combination of a drive motor and a lead screw nut mechanism, a power cylinder, a linear module, etc. On the premise that the two first adjustment assemblies can achieve relatively independent movement, the components constituting the two can be completely different or partially shared. For example, the same drive motor can be selectively (switchably) connected to the transmission mechanism corresponding to the first adjustment jaw or the second adjustment jaw.

[0224] In a possible implementation, the first adjustment jaw and the second adjustment jaw are equipped with a set of second adjustment components, and the second adjustment components can realize the movement of the first / second adjustment jaw along the longitudinal direction (vertical direction) thereof.

[0225] In a possible embodiment, the second adjustment assembly includes a second adjustment drive motor 23241, a cam 23242 and a second adjustment guide structure 23243, a reserved space is provided on the connection bracket of the adjustment jaw base, the power output shaft of the second adjustment drive motor is connected to the cam drive, and the cam is accommodated in the reserved space and abuts with the connection bracket (such as line contact), and the second adjustment guide structure is arranged on the bracket body of the adjustment jaw base and only allows the first / second adjustment jaw to move in the vertical direction. As in this example, the reserved space is a circular hole, and the cam abuts with the connection bracket corresponding to the position of the circular hole near the top. If the second adjustment guide structure is a second adjustment linear slide rail, a groove structure matching the second adjustment linear slide rail is correspondingly provided on the connection bracket of the adjustment jaw base. For example, the reserved space can also be other structural forms such as a square hole or a groove with an open bottom side, and the second adjustment guide structure can also be other structures such as an optical axis. In this way, under the driving action of the second adjustment drive motor, the cam abuts against the position near the top of the reserved space, thereby driving the connecting bracket of the adjustment jaw base to move in the vertical direction and thereby driving the first / second adjustment jaw to move (the first / second adjustment jaw is connected to the first adjustment linear guide rail of the connecting bracket arranged on the aforementioned adjustment jaw base). At the same time, due to the constraint of the second adjustment guide structure, the first / second adjustment jaw can achieve fine-tuning of its position along the longitudinal direction.

[0226] In this way, when the central axis of the silicon rod in the clamped state is slightly offset from the horizontal direction (in the vertical direction), the two adjustment claws of the adjustment jaw assembly can be driven by the second adjustment assembly to move longitudinally, thereby causing a certain height difference between the clamping position of the fixed jaw assembly and the clamping position corresponding to the adjustment jaw assembly. Such a height difference can effectively suppress the displacement of the offset.

[0227] It is understandable that the structural form of the aforementioned second adjustment component is only an exemplary description, and those skilled in the art can flexibly change it according to actual needs, such as changing the cam to an eccentric shaft or other eccentric structures. In addition, a second adjustment component can be configured for each of the first / second adjustment clamps, or a portion of the second adjustment components of the two can be shared. And, under the premise of being able to achieve lifting in the height direction, other drive transmission forms can also be used to achieve it, such as changing the drive motor to a power cylinder, a linear module, a rotating module, etc., such as changing the cam to a screw nut mechanism, a worm gear pair, a gear rack mechanism, a sprocket chain mechanism, etc. Exemplarily, the power cylinder pushes a pair of connecting blocks with inclined surfaces to move, and the inclined surfaces of the pair of connecting blocks are respectively provided with lifting wheels that can roll along them, and the wheel axles of the lifting wheels are arranged on the connecting bracket of the adjustment clamp base.

[0228] In a possible implementation, a first adjustment jaw and a second adjustment jaw in the adjustment jaw group are each equipped with a photoelectric switch on both sides along the axial direction of the silicon rod, and the two pairs of photoelectric switches are mainly used to measure the length of the silicon rod before loading. The following describes the determination of the length of the silicon rod by taking a pair of photoelectric switches (respectively referred to as the first photoelectric switch and the second photoelectric switch) configured in the first adjustment jaw.

[0229] For example, the process of clamping a silicon rod by a fixed jaw assembly and an adjustable jaw assembly is usually as follows: first, the fixed jaw assembly clamps one side of the rod, and then the adjustable jaw assembly starts from the initial clamping position of the silicon rod and moves along the length direction of the silicon rod. It is known that the distance between the initial clamping position of the adjustable jaw assembly and the front end (left side) of the silicon rod is a, the distance between the first pair-beam photoelectric switch on the left and the center of the first adjusting jaw is n, and the distance between the second pair-beam photoelectric switch on the right and the center of the first adjusting jaw is m.

[0230] Based on this, for a silicon rod with a longer length, the first / second paired photoelectric switch can both receive signals, and the first / second adjustment jaw can be moved along the axis direction of the silicon rod until the second paired photoelectric switch on the right side receives no signal. At this time, according to the detected distance x of the first / second adjustment jaw moving to the right, the length L=a+m+x of the silicon rod can be determined. For a silicon rod with a shorter length, the first paired photoelectric switch on the left side can receive signals while the second paired photoelectric switch on the right side cannot receive signals, and the first / second adjustment jaw can be moved along the axis direction of the silicon rod until the first paired photoelectric switch on the left side receives no signal. At this time, according to the detected distance x of the first / second adjustment jaw moving to the right, the length L=a+xn of the silicon rod can be determined.

[0231] [Both directions can be expanded to multiple grinding stations]

[0232] In this embodiment, the gantry assembly is configured with only one set of grinding stations as an example (such as mainly including a grinding operation area, a loading area, and a unloading area). If necessary, since the grinding machine of the utility model is relatively compact in structure, there is a certain amount of expandable space corresponding to the moving space of the lateral moving assembly. Therefore, multiple sets of grinding stations can be arranged along the movement direction corresponding to the lateral moving assembly, such as each set of grinding stations can be relatively independent in structure, that is, each set of grinding stations includes a grinding operation area, a loading area, and a unloading area. If necessary, the structure of the loading area and / or the unloading area can be shared or partially shared, that is, the number of the loading area and / or the unloading area is less than the number of the grinding work area.

[0233] In addition, since the clamping assembly is fixed in a relatively fixed state after clamping the silicon rod, the space along the length direction of the silicon rod is greatly saved. If necessary, there may be a certain amount of expandable space in the moving space corresponding to the lateral moving assembly itself. Therefore, multiple grinding work areas can be arranged along the movement direction corresponding to the lateral moving assembly. Exemplarily, in the case where multiple grinding work areas are roughly collinear, a loading area and a unloading area can be shared, and in the case where they are not collinear (such as staggered arrangement), multiple grinding work areas can share or separately configure the loading area and the unloading area corresponding to them.

[0234] Based on the above structure, in a possible implementation mode, the main operations of the transfer mechanism in the grinder of the utility model include four steps: V-shaped grabbing of rough rods, V-shaped loading, 0° grabbing of finished rods, and 0° placement of finished rods (unloading).

[0235] 1. V-shaped grabbing stick:

[0236] In one possible embodiment, when the transfer mechanism is ready to load and clamp the rough rod to be ground, the slide moves horizontally along the gantry assembly with the help of the lateral moving assembly, thereby driving the clamping assembly arranged on the slide to move to the top of the loading assembly, and the clamping assembly moves downward with the help of the longitudinal moving assembly to a loading clamping position capable of grabbing the V-shaped rough rod placed on the loading assembly, and the two fixed / adjustable jaws of the fixed / adjustable jaw assembly move away from each other (releasing the first clamping space so that the silicon rod can be clamped smoothly on this basis).

[0237] For example, the usual clamping process is: first, the two fixed jaws of the fixed jaw assembly use the first clamping space corresponding to the V-shaped clamping to clamp the silicon rod, and because the first clamping space and the silicon rod at this time have a matching V-shaped posture, the centering operation of the silicon rod can be completed while the silicon rod is clamped. When the clamping operation of the fixed jaw assembly has been completed, the adjustment jaw assembly is moved along the length direction of the silicon rod (with the help of the switching assembly to put the fixed jaw assembly in the second state) to the set position and the two adjustment jaws are brought close to each other to clamp the rod material. In this process, the length of the silicon rod can be measured by two pairs of opposing photoelectric switches configured on the adjustment jaw assembly.

[0238] In the case where the posture of the silicon rod in the clamped state is slightly offset, the position of the silicon rod can be adjusted by adjusting the clamping jaw assembly. Specifically, if there is a certain displacement (lateral deviation) between the central axis of the silicon rod and the ideal position (vertical plane) when the silicon rod is clamped, the two first adjustment assemblies can drive the two independently movable adjustment claws to move in the same direction to suppress / eliminate this deviation. And if there is a certain angle (longitudinal deviation) between the central axis of the silicon rod and the horizontal plane when the silicon rod is clamped, the second adjustment assembly can be used to drive the two adjustment claws of the adjustment clamping jaw assembly to move longitudinally to suppress / eliminate this deviation.

[0239] 2. V-type feeding:

[0240] After the silicon rod is clamped, the longitudinal moving assembly drives the clamping claw assembly holding the silicon rod to move vertically upward, and the transverse moving assembly drives the slide including the longitudinal moving assembly and the clamping claw assembly to move along the gantry assembly to above the clamping position corresponding to the grinding device. On this basis, the longitudinal moving assembly drives the clamping claw assembly holding the silicon rod to move vertically downward to the clamping position of the grinding device. When the clamping assembly of the grinding device begins to clamp the silicon rod, the potential energy of the clamping claw assembly is removed so that the clamping claw assembly can move with the movement of the silicon rod. After the clamping assembly of the grinding device clamps the silicon rod firmly, the two pairs of jaws of the clamping claw assembly loosen from each other, thereby releasing the first clamping space (the clamping claw assembly loosens the silicon rod).

[0241] After the restraint of the silicon rod by the clamping jaw assembly is released, the clamping jaw assembly can be driven to a position that does not interfere with grinding (waiting grinding position) by the aforementioned lateral moving assembly and longitudinal moving assembly. At this time, the side and edge grinding of the silicon rod can be performed by the grinding device.

[0242] 3. Grab the finished rod at 0°:

[0243] After the grinding operation of the silicon rod is completed, a finished rod with surface accuracy that meets the standard can be obtained. At this time, the clamping claw assembly (the second clamping space) can be driven to the post-grinding clamping position of the silicon rod by the lateral moving assembly and the longitudinal moving assembly. On this basis, the two pairs of clamping claws are brought close to each other and the finished rod is grasped in a conventional 0° clamping manner. In addition, the two pairs of anti-falling hooks are pivoted to a position that can provide auxiliary pressing force / supporting force to the finished rod (hooking the silicon rod hook) to prevent the silicon rod with surface accuracy that meets the standard from falling.

[0244] After the silicon rod is grasped, the clamping jaw assembly is driven to move vertically upward by the longitudinal moving assembly, and the clamping jaw assembly including the longitudinal moving assembly and the slide is driven to move to the unloading position of the unloading assembly by the transverse moving assembly.

[0245] 4. 0° blanking:

[0246] The longitudinal moving assembly drives the clamping jaw assembly to move vertically downward to the unloading position corresponding to the unloading assembly, and then the two pairs of clamping jaws of the clamping jaw assembly are released from each other, and the two pairs of anti-falling hooks are pivoted and released, thereby releasing the second clamping space, and the silicon rod can fall onto the unloading table of the unloading assembly, and a complete operation is completed. For example, the finished rod can be connected with the unloading assembly through AGV to transport the finished rod to a location such as a slicer station.

[0247] Afterwards, the gripper assembly including the slide and the longitudinal moving assembly can be moved back to the aforementioned loading position to prepare for the second loading and grabbing.

[0248] In a specific embodiment, the operation process of the grinding machine of the utility model generally includes the following steps:

[0249] S1. Place the silicon rod (rough rod to be processed) on the loading assembly.

[0250] S2. The lateral moving assembly is started, and the clamping jaw assembly is thus transferred laterally to a loading position corresponding to the loading assembly.

[0251] S3. The clamping jaw assembly is opened to a position where the silicon rod can be freely accommodated, such as opened to the maximum position.

[0252] S4. Use the clamping jaw assembly to clamp the silicon rod.

[0253] S5. The vertical moving assembly starts, and the gripper assembly grabs the silicon rod upward.

[0254] S6. The lateral moving assembly is started, and the clamping jaw assembly is transferred laterally to a position corresponding to the grinding device (processing area).

[0255] S7, the vertical moving assembly starts, and the clamping jaw assembly returns to the material-waiting state. At this time, the silicon rod can be ground.

[0256] S8. After the grinding operation is completed, the vertical moving assembly is started, and the clamping jaw assembly is longitudinally transferred to the position of the grinding device (processing area) and clamps the silicon rod.

[0257] S9, the lateral moving assembly is started, and the clamping jaw assembly is transferred laterally to the unloading position corresponding to the unloading assembly.

[0258] S10, the clamping jaw assembly is released, thereby transferring the silicon rod to the unloading area of ​​the unloading assembly.

[0259] S11, the lateral moving component is started, so that the transfer mechanism returns to the waiting state in the lateral direction.

[0260] At this point, the grinding operation including silicon rod transfer is completed.

[0261] [Grinding device in which the chuck assembly and the silicon rod it holds are stationary and the grinding assembly reciprocates]

[0262] The structure of the current grinding machine mainly includes a movable slide that can move along the length direction of the silicon rod, a clamping assembly that can clamp the silicon rod and a grinding assembly that can grind the silicon rod. Based on such a structure, the workflow of the existing grinder when grinding the silicon rod is as follows: the clamping assembly clamps the silicon rod (the clamping assembly usually includes a movable chuck and a fixed chuck, and the movable chuck moves relative to the fixed chuck to clamp the silicon rod), and the clamping assembly that clamps the silicon rod is driven to slide on the movable slide, so that the grinding assembly that is relatively fixed in position along the length direction of the silicon rod can grind the side and chamfer of the entire length range of the silicon rod along with the sliding of the clamping assembly, thereby completing the grinding operation of the silicon rod.

[0263] Different from the existing grinding machines, the grinding machine of the present invention adopts an operation mode in which the grinding assembly 13 moves along the length direction of the silicon rod 3, while the chuck assembly 12 (usually including a fixed chuck and a movable chuck, or both movable chucks) is relatively fixed in position after clamping the silicon rod. Specifically, the movement of the grinding assembly during the grinding operation of the silicon rod includes rotational movement and linear movement along the length direction of the silicon rod. Among them, the grinding assembly usually includes a rough grinding wheel and a fine grinding wheel, and the rotational movement is mainly to grind the surface of the silicon rod by rotating the rough grinding wheel and the fine grinding wheel while ensuring a certain cutting depth and cutting force along the radial direction of the silicon rod. Along with the linear movement of the grinding assembly along the length direction of the silicon rod, the chamfer between the side of the silicon rod and the adjacent side can be ground. Exemplarily, the linear motion of the grinding assembly along the length direction of the silicon rod is achieved as follows: the grinding machine includes a slide mechanism, and the grinding assemblies arranged in pairs are slidably arranged on the slide mechanism, so that under the action of corresponding driving transmission components, the grinding assemblies can move along the length direction of the silicon rod.

[0264] In a possible implementation, the grinding assembly 13 mainly includes a fine grinding wheel 131 for fine grinding of silicon rods, and a rough grinding wheel 132 for rough grinding of silicon rods. In the present invention, the rough grinding wheel and the fine grinding wheel are concentrically arranged at the same station, and the rough grinding wheel is freely accommodated in the reserved space formed inside the fine grinding wheel. In this way, the grinding assembly can realize rough grinding and fine grinding of silicon rods at the same station.

[0265] In a possible embodiment, the grinding assembly also includes a composite shaft, the composite shaft includes a bearing box 133, the bearing box includes a first transmission shaft (bushing) 134 of a cylindrical structure and a second transmission shaft 135 (inner shaft) contained in the cylindrical structure, wherein the bushing is connected to the fine grinding wheel so as to drive the fine grinding wheel to be connected when the bushing rotates, and the second transmission shaft is connected to the rough grinding wheel so as to drive the rough grinding wheel to be connected when the second transmission shaft rotates. The first transmission shaft and the second transmission shaft are connected by a guide flat key, so that the first transmission shaft and the second transmission shaft can be driven to rotate synchronously by a driving component such as a motor. Exemplarily, the motor 136 is connected to the rear end of the composite shaft through a pulley mechanism 137 and thus drives the first transmission shaft and the second transmission shaft to rotate synchronously.

[0266] Based on this, a mechanism is mainly configured for the second transmission shaft corresponding to the rough grinding wheel to realize its extension and retraction, so as to realize the switching of the rough grinding operation and the fine grinding operation. Specifically, when the silicon rod needs to be rough ground, it is extended relative to the fine grinding wheel, and when the silicon rod needs to be fine ground, it is retracted relative to the fine grinding wheel (reserved space). Exemplarily, one way to realize the switching of the rough grinding operation and the fine grinding operation of the rough grinding wheel is that the telescopic mechanism includes a spring, and the second transmission shaft is in a state of retraction relative to the fine grinding wheel under the action of the preload force of the spring. In this way, when the silicon rod needs to be fine ground, it is sufficient to maintain a state without external force. And when the silicon rod needs to be rough ground, the rough grinding wheel associated with it is extended out of the fine grinding wheel by applying external force to the spring. For example, an external force mechanism such as a power cylinder, a linear module, or a drive transmission mechanism capable of realizing telescopic movement can be used to apply an external force to the pressure cover supporting the rear end of the bearing box, so that the spring is deformed under the action of the external force and the rough grinding wheel is extended.

[0267] Compared with the method of setting up the rough grinding wheel and the fine grinding wheel at separate workstations, the grinding assembly of the utility model integrates the rough grinding wheel and the fine grinding wheel with the help of a bearing box and sets them in the same workstation, that is, the grinder only needs to reserve the same workstation to simultaneously realize the rough grinding and fine grinding operations on the silicon rod, and the structure is more compact, which greatly reduces the installation space of the grinding assembly. Corresponding to the setting of the same workstation, the grinder will reduce a set of supporting mechanisms of the grinding assembly, saving the number of components. In addition, since the grinding assembly of the utility model needs to move back and forth along the length direction of the silicon rod, the integrated setting can also effectively avoid problems such as the impact on grinding accuracy caused by the movement of multiple components, and is therefore more compatible with the operation mode of the grinder of the utility model.

[0268] [Can be used as loading and unloading components]

[0269] In a possible embodiment, the loading and unloading assembly 11 mainly includes a material storage table assembly 111, a material table assembly 112 and a material table flipping assembly 113, wherein the material table assembly can transfer the silicon rods (rough rods) to be processed to a designated position to wait for loading, or receive processed silicon rods (finished rods) for unloading. The material storage table assembly 112 can be placed on the square rods waiting for loading / unloading, and the square rods can be transferred along their length direction. The material table flipping assembly 113 is configured on the material table assembly, and the material table flipping assembly can flip the square rods placed therein along the axis of the square rods at a certain angle according to the requirements of loading / unloading, such as corresponding to the aforementioned loading requirement (first clamping space) to the state where the angle between the side and the horizontal plane is 45°, or corresponding to the aforementioned unloading requirement (second clamping space) to the state where the angle between the side and the horizontal plane is 0°.

[0270] In a possible embodiment, a connecting component is provided between the material storage table component and the material table component so that the square rods can be smoothly transferred between the material storage table component and the material table component, and through such a connection, the loading and unloading components can better adapt to the transfer requirements of square rods of different lengths.

[0271] In a possible implementation, the storage platform assembly 111 and the material platform assembly 112 are provided with a detection assembly to detect, for example, the presence or absence of silicon rods, the length of the rods, etc. As in this example, the detection assembly contains multiple pairs of photoelectric switches. Specifically, photoelectric switches 116 are provided at the front end of the material platform assembly and the front, middle, and rear ends of the storage platform assembly.

[0272] In a possible implementation, the material platform assembly 122 mainly includes a material platform base and a material platform transmission mechanism, such as the material platform base includes a material platform support seat 1221 and a material platform frame 1222 disposed on the material platform support seat.

[0273] In a possible implementation, the material table transmission mechanism conveys silicon rods by belt transmission. In this example, two pairs of shaft support seats 1223 with bearings inside are provided on the top of the material table frame, a support shaft 1224 is installed between each pair of shaft support seats, and a pair of synchronous wheels 1225 are installed on each shaft, and the synchronous wheels can be fixed to the support shaft by means of top screws, expansion sleeves, keys, etc. Among them, one of the two support shafts is equipped with a material table drive motor 1226 and is therefore called the active shaft, and the other is not equipped with a material table drive motor and is therefore called the driven shaft. A pair of synchronous wheels at corresponding positions on the two shafts are supported synchronously, and therefore drive the silicon rods placed on the synchronous belt to move with the synchronous belt under the driving action of the material table drive motor.

[0274] In this example, an adjustment screw may be provided at the end of the shaft support seat of the driven shaft, such as the adjustment screw passing through the shaft support seat and being threadedly connected to the driven shaft. In this way, the distance between the driven shaft and the driving shaft can be pulled and the synchronous belt can be tightened by pulling the adjustment screw in the guide groove of the shaft support seat adapted thereto. A synchronous belt support plate may be provided below the synchronous belt, and the top of the synchronous belt support plate has a rib to guide the synchronous belt during transmission. In addition, baffles may be provided at positions on both sides of the material platform frame corresponding to the synchronous belt to prevent silicon rods from falling when being transported by the synchronous belt. For example, the baffle may include a plurality of baffles arranged at intervals along the transmission direction of the synchronous belt or a strip-shaped structure. For example, the long strip-shaped baffle is provided on the material platform frame through a plurality of support strips or support ribs. Taking the baffle as a long strip structure as an example, the baffle may be made of non-metallic material or a buffer layer such as a polyurethane layer may be added to the inner side of the baffle so that after the dropped silicon rod is successfully intercepted, phenomena such as silicon rod damage may occur.

[0275] In a possible implementation, the material platform flip assembly 115 mainly includes a material platform flip driving component 1151 and a material platform flip bracket 1152, wherein the material platform flip bracket is pivotally arranged on the aforementioned material platform frame 1222 and forms a bearing space capable of bearing silicon rods, and the material platform flip driving component is used to drive the material platform flip bracket to flip relative to the material platform frame and thus change the posture of the silicon rods carried thereon. In this example, the material platform flip bracket includes a bottom wall portion and a side wall portion.

[0276] In a possible implementation, the material platform flip bracket is pivotally arranged on the aforementioned material platform frame in the following manner: two flip shaft support seats equipped with bearings are arranged at the bottom of the material platform flip bracket 1152, and the flip shaft support seats are fixedly arranged on the material platform frame, such as a flip shaft guide seat can be arranged between the two flip shaft support seats, and the flip shaft 1153 is pivotally arranged on the flip shaft support seat and the flip shaft guide seat. The material platform flip driving component drives the material platform flip bracket to flip by driving the flip shaft to rotate.

[0277] In a possible implementation, since the material table flip bracket needs to be in direct contact with the silicon rods, a material or structure with a buffering function can be provided on the material table flip bracket, such as adding a non-metallic protective plate inside the material table flip bracket.

[0278] In a possible embodiment, a material table flipping clamping assembly 1154 is provided at a position near the end of the material table flipping bracket in the length direction and opposite to the side wall portion of the flipping bracket, so as to clamp the silicon rod when the silicon rod rotates to ensure the reliability of the flipping operation.

[0279] In a possible implementation, the material table flipping bracket is provided with a material table flipping guide wheel near the end in the length direction thereof, and a first material table flipping detection switch is provided near the material table guide wheel to detect whether the silicon rods are delivered to the right position.

[0280] In a possible embodiment, the material table flipping driving component is a power cylinder (such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc., and obviously it can also be a mechanism or a motor that can provide linear drive composed of a linear module, a driving component and a transmission component. For example, in the case where the material table flipping driving component is a motor, the power output shaft of the motor should be connected to the flipping axis), the power cylinder is fixed to the aforementioned material table support seat, and the power output end of the power cylinder is fixed to the material table flipping bracket. In this way, by extending or retracting the power output end of the power cylinder, the material table flipping bracket can be rotated around the flipping axis, thereby changing the posture of the silicon rods carried thereon.

[0281] In a possible embodiment, the material platform flipping assembly is also provided with a material platform flipping limit assembly to determine the flipping range of the discharging platform flipping assembly. Exemplarily, the material platform flipping limit assembly includes a material platform flipping limit base, a material platform flipping limit screw and a material platform flipping buffer arranged thereon. The flipping angle of the flipping assembly can be adjusted by adjusting the material platform flipping limit screw, and the material platform flipping buffer is used to buffer the flipping motion with the help of the buffer when the flipping is in place, thereby protecting the silicon rods. In addition, a material platform flipping detection switch can be respectively provided at the initial position and the flipping position of the material platform flipping assembly to detect whether the material platform flipping assembly has returned to the initial position and whether it has flipped in place.

[0282] In a possible embodiment, the material storage platform assembly 111 mainly includes a material storage platform frame 1111 and a material storage platform transmission mechanism arranged on the material storage platform frame, wherein the material storage platform transmission mechanism is similar to the aforementioned material storage platform assembly, and also adopts the method of belt transmission to realize the silicon rod, which will not be repeated here. Exemplarily, since the material storage platform assembly needs to be connected with the external environment, a plurality of casters 1112 and foot cups 1113 can be provided at the bottom of the material storage platform frame, and when the material storage platform assembly needs to be moved, the foot cups are lifted (at this time, the casters are in contact with the ground). When the material storage platform assembly needs to be fixed, the foot cups are put down (at this time, the foot cups are in contact with the ground). For example, the combination of foot cups and casters can also be replaced by a forma wheel, etc.

[0283] It can be understood that the belt drive and its specific form are only an exemplary description of the material table / storage table transmission mechanism. Technical personnel in this field can adopt other structural forms of belt drives or other transmission methods besides belt drives to realize the transportation of silicon rods according to actual needs. For example, in addition to belt drives, the transportation of silicon rods can also be realized through the cooperation of sprockets and chains, belts and pulleys, guide rails and screw nut mechanisms, guide rails and gear rack pairs, power cylinders and guide rails, etc.

[0284] In a possible embodiment, the connection assembly 113 includes a connection bracket 1131 and a transition wheel assembly disposed on the connection bracket, and the transition wheel assembly includes a pair of first transition wheels 1132 (such as radially larger rollers, hereinafter referred to as large rollers) pivotally disposed on the connection bracket. Exemplarily, the large roller is pivotally disposed on the connection bracket in the following manner: the large roller is disposed on the transition wheel shaft, and the transition wheel shaft is disposed between a pair of transition wheel support seats fixedly disposed on the connection bracket. For example, in this example, the connection bracket is a bracket of a roughly L-shaped structure, the transition wheel shaft support seat is disposed on the lateral portion of the connection bracket, and the vertical portion of the connection bracket is mounted to the front end position of the storage platform frame of the aforementioned storage platform assembly.

[0285] In a possible implementation, a driven sprocket 1133 is provided on the transition wheel shaft, a driving sprocket is provided on the driven shaft of the storage platform assembly, and the driving sprocket and the driven sprocket are connected by a chain. A plurality of pairs of second transition wheels 1134 (such as radially smaller rollers, hereinafter referred to as small rollers) are also pivotally provided on the connection bracket. For example, in this example, a pair of small rollers are respectively arranged on both sides of a pair of large rollers along the conveying direction. For example, the surface of the large / small rollers should be a structure or material (such as a non-metallic material) that will not cause damage to the surface of the silicon rod. Through such an arrangement, it can be ensured that the silicon rod is better connected between the material platform assembly and the storage platform assembly, and can adapt to the transmission of square rods of various lengths.

[0286] It can be understood that the transmission of silicon rods on the transition wheel assembly through the cooperation of sprockets and chains is only one of the implementation forms. Technical personnel in this field can flexibly change it according to actual needs. For example, the driving sprocket can be set on the driving shaft of the material table assembly, and the cooperation of the sprocket and the chain can be changed to other methods such as the cooperation of gear pairs, synchronous belts and synchronous pulleys, belts and pulleys, guide rails and screw nut mechanisms, guide rails and gear rack pairs, cylinders and guide rails.

[0287] Based on the above structure, when the loading and unloading assembly is used as the loading assembly of the grinder, its working process generally includes: the silicon rods (rough rods) to be loaded can be placed in the carrying space of the storage table assembly by manual, robot, truss manipulator, KBK, AGV, conveyor line, etc., and the length of the silicon rods can be determined by the detection assembly. The storage table drive motor is started to smoothly convey the silicon rods to the material table assembly through the connection assembly by belt transmission. The material table assembly drive motor is started to convey the silicon rods into place by belt transmission (first material table detection switch). The material table flipping and clamping assembly presses the silicon against the side wall of the flip bracket. Under the action of the flipping drive component, the silicon rod flips 45° according to the demand to meet the loading demand compatible with the first clamping space mentioned above. The material table detection switch can detect whether the silicon rod is flipped into place. After flipping into place, the material table flipping and clamping assembly can release the silicon rod for the next step of grabbing.

[0288] When the loading and unloading assembly is used as the unloading assembly of the grinder, its working process generally includes: according to the unloading demand, the material table flip assembly flips to the 0° regular position to receive the silicon rods (finished rods) unloaded vertically, and the material table flip pressing assembly presses the finished silicon rods against the inner side of the side wall of the material table flip bracket. Under the action of the flip driving component, the material table flip assembly drives the rods back to the 0° position. When the second flip detection switch detects whether the silicon rods return to the 0° position, the material table flip pressing assembly releases the rods to facilitate the next step of unloading and transportation. If the unloading demand does not require the rods to flip, the flip-related actions can be omitted. The material table drive motor starts, and the silicon rods are output outward by belt transmission. In order to ensure the effectiveness of the connection assembly, the storage table drive component must also be started before the silicon rods reach the storage table assembly. If necessary, the silicon rods can be transported to any position of the storage table assembly to meet the smooth connection with manual, robot, truss manipulator, KBK, AGV, conveyor line and other unloading methods.

[0289] In one possible embodiment, a material storage table assembly is provided with a material storage table flip assembly 1114 at the end of the material storage table assembly away from the material storage table assembly along the length direction of the silicon rod, so that when the material storage table assembly is flipped open to the spliced ​​state, it can meet the storage needs of silicon rods with longer lengths, and when the material storage table assembly is flipped and folded, it can meet the storage needs of silicon rods with shorter lengths.

[0290] In a possible embodiment, the material storage table flip assembly 1114 mainly includes a material storage table flip plate 11141. Similar to the aforementioned material storage table flip plate, a non-metallic protective block 11142 is installed on the inner side (bottom wall and side wall) of the material storage table flip plate. A pair of mounting plates 11143 extend downward from the material storage table flip plate. An elongated hole extending in the vertical direction is provided on the mounting plate, and an arc-shaped slot hole is provided at the bottom end of the elongated hole. A non-metallic protective block is installed on the material storage table flip plate. A pair of mounting blocks 11144 corresponding to the pair of mounting plates are provided on the material storage table flip plate. The mounting blocks are provided with blocking screws, a first rotating shaft adapted to the elongated hole, and a second rotating shaft adapted to the slot hole. In this way, the state switching of the material storage table flip plate can be realized through two sets of cooperation.

[0291] When the length of the storage platform assembly is insufficient and the storage platform flip assembly needs to be used, the storage platform flip plate is dropped so that the two rotating shafts on the mounting block are respectively at the top of the two long holes of the storage platform flip bracket. The storage platform flip plate can be placed in a horizontal position by blocking the screws, which can lengthen and extend the storage platform assembly to accommodate the placement of rectangular bars. When the length of the storage platform assembly is sufficient, the storage platform flip plate is lifted so that the two rotating shafts on the mounting block are respectively at the bottom of the two long holes of the storage platform flip bracket. The storage platform flip plate is rotated so that the storage platform flip plate rotates around the upper rotating shaft, so that the storage platform flip plate can be placed in a vertical position, saving space. That is, when the length of the silicon rod is long and the length of the storage platform assembly is insufficient, the storage platform flip plate is unfolded, so that the storage platform assembly can be lengthened and extended, so that it can better accommodate the placement of long bars. When the silicon rod is short and the storage table assembly is long enough, the storage table flip plate is folded, thereby effectively saving the space occupied by the storage table assembly along the length of the silicon rod without interfering with the function of the storage table assembly.

[0292] In a possible implementation, the loading and unloading assembly further includes a protection assembly, which is mainly used to protect the loading and unloading assembly, such as a protection net or a light curtain.

[0293] It can be seen that the grinding machine of the utility model mainly has the following advantages:

[0294] 1) Based on the transfer mechanism, the grinding machine of the utility model can be compatible with the transportation operation of loading before grinding and unloading after grinding, which can significantly reduce the cost. In addition, the lateral moving component and the longitudinal moving component of the transfer mechanism have high transmission accuracy, which can ensure the reliability of the transportation of loading before grinding and unloading after grinding.

[0295] 2) By designing the dual clamping spaces of the clamping jaw assembly differently, the transfer mechanism can better meet the transport operations for loading before grinding and unloading after grinding. Specifically, the clamping jaw assembly performs V-shaped clamping (rough rod before grinding) and 0° clamping (finished rod after grinding) on ​​the silicon rod through the first clamping space and the second clamping space. In addition, by configuring an anti-falling assembly for the second clamping space corresponding to the 0° clamping, the finished rod material can be effectively prevented from falling.

[0296] 3) The clamping jaw assembly can measure the length of the silicon rod during the feeding process (before clamping), saving the cycle time of the entire grinding operation. The feeding clamping jaw assembly mainly realizes the grabbing and centering operation of the silicon rod through the cooperation of the threaded segments at both ends of the screw nut mechanism, and the feeding clamping jaw drive motor can directly calculate the cross-sectional size of the silicon rod while driving the screw nut mechanism, saving cycle time.

[0297] 4) The adjustment jaw assembly in the jaw assembly is configured with a first adjustment assembly capable of achieving lateral fine-tuning and a second adjustment assembly capable of longitudinal fine-tuning, so that the silicon rods with certain deviations in gripping size / posture can be more adaptable to the silicon rods.

[0298] 5) During the process of the clamping jaw assembly discharging materials to the upper material assembly or the lower material assembly, no relative displacement occurs between the silicon rod and the clamping jaw assembly, thereby reducing the risk of damage to the silicon rod, thereby ensuring the reliability of the grinder.

[0299] It can be seen that in the grinding machine of the utility model, the rough rod can be transferred to the grinding device in a V-shaped clamping manner through the cooperation of the transfer mechanism and the feeding assembly, and on this basis, the silicon rod is fixed and the grinding assembly reciprocates to complete the grinding operation of the silicon rod. Through the cooperation of the transfer mechanism and the unloading assembly, the finished rod can be transferred out of the grinding device in a conventional 0° surface clamping manner.
