Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment for hard and brittle materials, and in particular to an integrated grinding and opening machine, a control method for the integrated grinding and opening machine, a computer-readable storage medium, and a computer device. Background Art

[0002] Taking silicon rods as an example, the processing devices for hard and brittle materials usually include a squaring device for cutting round rods into square rods, a grinding device for grinding the square rods, and a cutting device for slicing the ground square rods. In the case where there is a possibility of connection between the above-mentioned different processing links, some of the devices can be integrated and designed.

[0003] For example, there are integrated squaring and grinding machines on the market. Specifically, the functions corresponding to the squaring device and the functions corresponding to the grinding device are integrated, so that the squaring and grinding operations of the silicon rods can be completed on the same integrated squaring and grinding machine. However, the current integrated squaring and grinding machines usually have the following problems: the workstations corresponding to the functions of the squaring device, the workstations corresponding to the functions of the grinding device, and the workstations corresponding to the functions of the cutting device are still basically consistent with the functions before integration in terms of functions. Therefore, there is still room for improvement in the collaboration between the different workstations after integration. In the case where the workstation includes multiple functions, the loading and unloading operations corresponding to the workstations are still relatively independent. Therefore, there is still room for improvement in the structure related to the loading and unloading operations of the integrated squaring and grinding machine. Summary of the invention

[0004] In order to solve the above technical problems to at least a certain extent, in a first aspect, the present invention provides an integrated opening and grinding machine, which includes at least a first workstation, and the first workstation includes: a cutting device, which can perform at least a portion of squaring operations on the workpiece and / or cut the edges of the workpiece; a first grinding device, which can perform at least a portion of grinding operations on the workpiece; a loading and unloading device, which includes a rotating mechanism, so that: at least based on the activity of the rotating mechanism, the workpiece can be transferred from the external environment to the first workstation; and / or the workpiece can be transferred from the first workstation to the external environment.

[0005] Through such a structure, it is possible to achieve various processing of the workpiece through the first station. On this basis, through the setting of the rotary mechanism, the loading and unloading devices are structurally integrated to a certain extent, and a certain correlation is generated in operation. For example, the external environment can be other equipment connected to the integrated grinding machine, the surrounding environment of the integrated grinding machine, or directly transported to other places that are a certain distance away from the integrated grinding machine in space.

[0006] It is understandable that those skilled in the art can determine the specific structural form of the rotary mechanism, its relative position with the first station, and the corresponding activity mode and activity amount for switching between the loading operation and the unloading operation according to actual needs. For example, the activity may include telescopic movement, rotation, movement, etc. Taking rotation as an example, the rotation range may be 45°, 90°, 180°, etc.

[0007] For the above-mentioned integrated opening and grinding machine, in a possible implementation manner, the loading and unloading device includes a rotary jaw assembly, and the rotary jaw assembly includes the rotary mechanism and a loading jaw assembly and a unloading jaw assembly arranged on the rotary mechanism.

[0008] Through such a structure, it is possible to adapt the loading jaw assembly and the unloading jaw assembly to the workpiece through the activity of the rotary mechanism, thereby completing the corresponding loading operation or unloading operation on this basis.

[0009] It is understandable that those skilled in the art can determine the specific structural form of the upper / lower material clamping jaw assembly, the specific manner in which it is arranged on the rotary mechanism, and the relative position between the upper / lower material clamping jaw assemblies according to actual needs. For example, the structures of the upper / lower material clamping jaw assemblies can be the same or different.

[0010] For the above-mentioned integrated opening and grinding machine, in a possible implementation manner, the slewing mechanism includes a base assembly and a slewing frame pivotally arranged on the base assembly, and the loading jaw assembly and the unloading jaw assembly are arranged on the slewing frame.

[0011] Through such a configuration, a possible structural form of the swivel mechanism formed by the swivel jaw assembly is provided, and a specific activity form of the swivel mechanism is provided.

[0012] It is understandable that those skilled in the art can determine the specific implementation method of the rotation of the slewing frame relative to the base assembly based on actual needs, such as direct drive by human power, motors and other driving components, or a rotating module including a driving component and a transmission mechanism (such as a combination of a motor and a gear pair, etc.).

[0013] For the above-mentioned integrated opening and grinding machine, in a possible implementation manner, the slewing mechanism includes a slewing base, the slewing frame is pivotally disposed on the slewing base, and the slewing base is disposed on the base assembly.

[0014] Through such a structure, a possible connection relationship between the revolving frame and the base assembly is provided. Specifically, the two are indirectly connected by introducing an intermediate component.

[0015] It is understandable that those skilled in the art can determine the specific connection method between the slewing frame, the slewing base and the base assembly according to actual needs, such as both adjacent ones can rotate relative to each other or one of them is fixedly connected.

[0016] For the above-mentioned opening and grinding machine, in a possible embodiment, the base assembly includes: a first transmission assembly that can move along a first direction; and a second transmission assembly that is arranged on the first transmission assembly and can move along a second direction that is angled with the first direction; wherein the rotating base is arranged on the base assembly in a manner that it can move along the first direction and / or the second direction.

[0017] With such a structure, the revolving frame can realize movement in the first and / or second direction in addition to the aforementioned rotation, so that on this basis it is expected that the upper / lower material clamping jaw assembly can realize more diverse movement forms during the switching process.

[0018] It is understandable that those skilled in the art can determine the specific direction of the first / second direction and the angle between the two according to actual conditions. Exemplarily, the two are two mutually perpendicular directions in a horizontal plane.

[0019] For the above-mentioned integrated opening and grinding machine, in a possible implementation manner, the second transmission assembly includes a screw and nut mechanism, and the rotary base is fixedly connected to the nut of the screw and nut mechanism via a nut seat.

[0020] Through such a structure, a specific connection method between the swivel base and the base assembly is provided.

[0021] In this way, the rotary drive component drives the rotary frame to rotate relative to the rotary base, the rotary base moves in the second direction relative to the second transmission component, and the second transmission component moves in the first direction relative to the first transmission component. Therefore, it is expected to achieve state switching between the upper / lowering clamping jaw assemblies through one of the three movements or activities, thereby achieving better loading and unloading operations for the workpiece.

[0022] For the above-mentioned integrated grinding and opening machine, in a possible implementation manner, the base assembly is provided with a water receiving tray.

[0023] With such a structure, water droplets carried on the silicon rods can drip into the water receiving tray, thereby ensuring the cleanliness of the rotary mechanism.

[0024] It is understandable that those skilled in the art can determine the structure, number and location of the water receiving tray on the base assembly according to actual needs. For example, the water receiving tray can be arranged on the first transmission assembly and / or the first transmission assembly, or one or more carriers for the water receiving tray can be added.

[0025] For the above-mentioned integrated opening and grinding machine, in a possible implementation manner, the rotating mechanism includes a rotating drive component, and the rotating drive component can drive the rotating frame to rotate relative to the base assembly. A rotating space is formed in the rotating frame, and at least a portion of the rotating drive component is located in the rotating space.

[0026] With such a configuration, it is possible to improve the compactness of the structure of the rotary mechanism.

[0027] For the above-mentioned integrated opening and grinding machine, in a possible implementation manner, the loading clamping jaw assembly and / or the unloading clamping jaw assembly includes at least one pair of clamping jaws capable of clamping the workpiece.

[0028] By such a configuration, it is possible to reliably clamp the workpiece by at least one pair of clamping jaws. For example, the number of pairs of clamping jaws included in the upper / lower material clamping jaw assembly and the structural form of the clamping jaws can be the same or different.

[0029] For the above-mentioned opening and grinding machine, in a possible implementation manner, the loading jaw assembly and / or the unloading jaw assembly includes: a plurality of pairs of jaws distributed along the length direction of the workpiece; or one or more pairs of jaws, at least a portion of the one or more pairs of jaws being able to move along the length direction of the workpiece.

[0030] By such a configuration, the workpiece can be clamped more reliably by multi-point clamping or position-changing clamping. For example, the loading clamp assembly includes two pairs of clamps, one of which is relatively fixed in position along the length direction of the workpiece, and the other pair can move along the length direction of the workpiece.

[0031] It is understandable that those skilled in the art can determine the specific implementation method of the clamping jaw to achieve its movement according to actual needs, such as through a power cylinder or a linear module.

[0032] For the above-mentioned opening and grinding machine, in a possible implementation manner, the loading jaw assembly and / or the unloading jaw assembly includes: one or more pairs of jaws; a first jaw driving component, which can drive at least one pair of the one or more pairs of jaws to move in a direction approaching / moving away from each other; a second jaw driving component, which can drive at least one pair of the one or more pairs of jaws to move in the direction of the workpiece.

[0033] Through such a structure, a possible structural form of the upper / lower material clamping jaw assembly is provided, such as the first / second clamping jaw driving component can be a retractable power cylinder, a linear module (such as a combination of a motor and a screw nut mechanism), etc.

[0034] For the above-mentioned opening and grinding machine, in a possible implementation manner, the loading jaw assembly and / or the unloading jaw assembly includes: a pair or more pairs of jaws distributed along the length direction of the workpiece; a rack and pinion pair, which includes a gear and a first rack and a second rack meshing with the gear, and the first rack and the second rack are respectively fixed to two jaws of one pair of jaws.

[0035] Through such a configuration, a possible structural form of a pair of clamping jaws clamping a workpiece is provided. For example, the component providing the driving force may be connected to the gear or the first / second rack.

[0036] For the above-mentioned integrated opening and grinding machine, in a possible implementation manner, the integrated opening and grinding machine includes: a second workstation, which includes a second grinding device, and the second grinding device can perform at least a portion of grinding operation on the workpiece.

[0037] With such a configuration, it is possible to realize grinding work on a workpiece by combining two stations.

[0038] It is understandable that those skilled in the art can determine the specific allocation method of the grinding operation between the first station and the second station according to actual needs.

[0039] For the above-mentioned integrated grinding machine, in a possible implementation manner, the grinding operation performed on the workpiece includes a first type of grinding operation performed on the edge of the workpiece and a second type of grinding operation performed on the side of the workpiece, wherein the first grinding device and the second grinding device are capable of performing the first type of grinding operation and / or the second type of grinding operation on the workpiece; and / or wherein the cutting device performs at least a portion of the first type of grinding operation by cutting the edge of the workpiece.

[0040] Through such a structure, the possibility of the integrated grinding machine to complete the grinding operation is provided. Exemplarily, the completion of the first type of grinding operation includes the following steps: first cutting the edge and then grinding the edge.

[0041] For the above-mentioned integrated grinding and opening machine, in a possible implementation manner, the first grinding device and the cutting device can perform the first type of grinding operation on the workpiece; and / or the second grinding device can perform the first type of grinding operation and / or the second type of grinding operation on the workpiece.

[0042] This configuration provides the possibility of performing the first type of grinding operation on the workpiece.

[0043] For the above-mentioned integrated grinding and opening machine, in a possible implementation manner, the first grinding device includes first grinding head assemblies arranged in pairs, and the first grinding head assemblies are arranged at the first workstation in a telescopic manner.

[0044] Through such a configuration, it is possible to achieve the corresponding grinding operation on the workpiece through the telescopic movement of the first grinding head assembly, and avoid cutting between it and the cutting operation corresponding to the first station based on the telescopic movement. Obviously, the technology in this field can determine the specific driving transmission method for achieving telescopic movement according to actual needs.

[0045] For the above-mentioned integrated cutting and grinding machine, in a possible implementation manner, the cutting device includes cutting head assemblies arranged in pairs, wherein the first grinding head assembly and the cutting head assembly are arranged relatively independently or at least partially associated.

[0046] With such a configuration, it is possible to square the workpiece at the first station by cutting.

[0047] It is understandable that those skilled in the art can determine whether the first grinding head assembly and the cutting head assembly are relatively independently arranged or at least partially arranged in association according to actual needs. Taking the at least partially arranged in association as an example, those skilled in the art can determine the degree of association and the specific manner of association according to actual needs.

[0048] For the above-mentioned integrated cutting and grinding machine, in a possible implementation manner, the cutting head assembly and the first grinding head assembly are arranged at the first station in a manner of being lifted and lowered simultaneously.

[0049] Through such a configuration, a specific structural form of the first workstation is provided.

[0050] It is understandable that those skilled in the art can determine the specific way to achieve simultaneous lifting of the two according to actual needs, such as the two are relatively independent in physical structure and are lifted and lowered simultaneously in a linkage control manner, or the two are physically connected through an intermediate component and the simultaneous lifting is achieved by controlling the intermediate component.

[0051] For the above-mentioned integrated cutting and grinding machine, in a possible implementation manner, the cutting device includes a liftable cutting wheel seat, and the first grinding head assembly and the cutting head assembly are arranged on the cutting wheel seat.

[0052] Through such a configuration, a specific structural form of the first station is provided. For example, the simultaneous lifting of the cutting machine head assembly and the first grinding head assembly can be achieved by (including but not limited to) controlling the lifting of the cutting wheel seat.

[0053] For the above-mentioned integrated grinding and opening machine, in a possible implementation manner, the second grinding device includes a second grinding head assembly, and the second grinding head assembly includes a rough grinding wheel and a fine grinding wheel.

[0054] Through such a configuration, a specific structural form of the second workstation is provided.

[0055] For the above-mentioned opening and grinding machine, in a possible embodiment, the second workstation includes a composite shaft assembly, the composite shaft assembly includes a first transmission shaft and a second transmission shaft telescopically accommodated in the first transmission shaft, the rough grinding wheel and the fine grinding wheel are respectively connected to one of the first transmission shaft and the second transmission shaft, so that: through the telescopic movement of the second transmission shaft, the rough grinding wheel or the fine grinding wheel connected thereto can be in a working state for grinding the workpiece.

[0056] For the above-mentioned integrated opening and grinding machine, in a possible embodiment, the integrated opening and grinding machine includes a clamping and transferring device, which can be docked with the loading and unloading device, and deliver the workpiece from the loading and unloading device to the working area of ​​the first workstation and / or the second workstation, or deliver the workpiece from the working area of ​​the first workstation and / or the second workstation to the loading and unloading device; and / or the clamping and transferring device can transfer the workpiece between the working areas of the first workstation and / or the second workstation; and / or in the case where the working area of ​​the first workstation and / or the second workstation includes multiple sub-working areas, the clamping and transferring device can transfer the workpiece between different sub-working areas.

[0057] Through such a structure, it is possible to seek to ensure the operation continuity of the grinding machine through the clamping and transferring device. For example, the sub-operation area here can be understood as: multiple operations can be performed in one station, and the area corresponding to each operation can be called a sub-operation area. Alternatively, when processing a workpiece in a station, multiple steps are required, and different steps need to be performed at different locations, then the area corresponding to each step can be called a sub-operation area.

[0058] For the above-mentioned opening and grinding machine, in a possible implementation manner, the clamping and transferring device includes a rotating worktable and a clamping and transferring column arranged on the rotating worktable, and the clamping and transferring column is provided with: a clamping head assembly, which includes a first clamping head and a second clamping head, and the workpiece can be clamped between the first clamping head and the second clamping head; and / or an edge skin supporting assembly, which can tighten the upper end surface of the edge skin produced by opening the square.

[0059] Through such a configuration, a specific structural form of the clamping and transferring device is provided.

[0060] For the above-mentioned opening and grinding machine, in a possible implementation manner, the opening and grinding machine includes a workbench, the rotating workbench is rotatably arranged on the workbench, and the basic workbench is provided with: an edge skin support assembly, which can tighten the lower end surface of the workpiece corresponding to the position of the edge skin; and the edge skin support assembly is movably arranged on the workbench.

[0061] Through such a structure, a specific structural form of the opening and grinding integrated machine is provided.

[0062] Specifically, by configuring a clamping head assembly, a side skin support assembly and a side skin support assembly on the clamping and transporting column, it can be ensured that the cutting / grinding operation can be completed smoothly. Under this premise, the size of the whole machine of the opening and grinding machine is made more compact. Through the movement of the side skin support assembly, it can be avoided that the side skin removal and other operations of the opening and grinding machine are interfered with by the side skin support assembly.

[0063] Since the time corresponding to the workstation of the square cutting operation and the time corresponding to the grinding workstation are not coordinated, specifically, the square cutting time is short and the grinding time is long, the square cutting and grinding integrated machine with a single-station combination often has the problem of long waiting time for the processing station, especially being greatly affected by the grinding station. Based on this, in a preferred embodiment of the present invention, by splitting the grinding operation, the overall efficiency of the square cutting and grinding integrated machine is guaranteed through the cooperation of the two workstations. On this basis, the grinding operation of the edges can also be split according to actual needs, such as splitting into an operation combination of first cutting and then grinding the edges, so that the square cutting and grinding integrated machine can be better connected at the time level on the basis of ensuring its functional integrity, thereby optimizing the performance of the square cutting and grinding integrated machine. In addition, when the square cutting and grinding integrated machine operates in different links, there is no need for secondary clamping, so it is expected to obtain higher processing accuracy and thus reduce the grinding allowance.

[0064] In a second aspect, the present invention provides a control method for an integrated opening and grinding machine, the integrated opening and grinding machine comprising a loading and unloading device and a clamping and transferring device and having a first workstation and / or a second workstation, the first workstation comprising a cutting device and a first grinding device, the second workstation comprising a second grinding device, the loading and unloading device comprising a rotary jaw assembly, the rotary jaw assembly comprising a rotary mechanism and a loading jaw assembly and a unloading jaw assembly arranged on the rotary mechanism, the control method comprising: making the rotary mechanism active so that: at least based on the activity of the rotary mechanism, the workpiece can be transferred from the external environment to the working area of ​​the first workstation and / or the second workstation via the loading jaw assembly and the clamping and transferring device; and / or the workpiece can be transferred from the working area of ​​the first workstation and / or the second workstation to the external environment via the clamping and transferring device and the unloading jaw assembly.

[0065] Through such a structure, a possible way is provided for the integrated opening and grinding machine to realize its multi-station loading and unloading operations.

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 the grinding machine well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present invention. Figures 1 to 58 The present invention is described in whole or in part.

Overview

[0190] Main reference Figure 1 to Figure 2 In a possible implementation manner, the integrated grinding machine 100 of the present invention mainly includes an equipment body, which includes a workbench 1, a grinding station 2 as a first station, and a grinding station 3 as a second station, wherein the grinding station 2 can not only cut the silicon rod 91 (which can be a round rod or a semi-finished square rod) (such as debonding four single sides of the raw material or debonding less than four single sides (such as a pair of equal sides) of the semi-finished square rod), but also cut the edges of the square rod by cutting (equivalent to chamfering). The grinding station 2 is mainly used for grinding the side and / or edge of the square rod by grinding (such as usually including rough grinding and fine grinding, etc.). The grinding station 2 is mainly used for grinding the side and / or edge of the square rod by grinding (if the grinding operation completed by the aforementioned first station is called the first part of the grinding operation, then this part of the grinding operation can be called the second part of the grinding operation. However, it should be noted that the first part and the second part here have no order in the level of grinding operation, nor does the sum of the two mean the whole grinding operation). For example, the cutting operation in the grinding station 2 is mainly to cut the round rod or the semi-finished square rod by wire saw cutting through the cutting wire 246 (such as diamond wire (cutting steel wire with tiny diamond particles embedded on the surface)). Obviously, the grinding operations of the grinding station 2 and the grinding station 3 can be interchanged, all the grinding operations can be completed by any one of the stations, or part or all of the grinding operations can be completed by other equipment other than the grinding machine of the present invention.

[0191] In a possible embodiment, the structure associated with the grinding station 2 mainly includes a cutting device 21, a first grinding device 26, a skin removal device 7 and a skin collection device 8, wherein the cutting device is mainly used to perform wire saw cutting on the silicon rod 91 such as the position corresponding to the generation of the skin 92, the edges and other parts, the first grinding device is mainly used to complete the grinding operation of at least a part of the silicon rod 91 (such as grinding the four edges of the square rod, etc.), the skin removal device 7 is mainly used to grab the skin material generated by the cutting from the position where the skin is generated in the grinding station 2 and transfer it to a position that does not interfere with the grinding operation of the grinding machine 100 (such as in this example, transfer it to the skin collection device 8), the skin collection device 8 is mainly used to collect the skin material generated by the squaring operation and remove it from the working area of ​​the grinding machine 100 or can be docked with a device that removes it from the working area of ​​the grinding machine 100.

[0192] In a possible embodiment, the structure associated with the grinding station 3 mainly includes a second grinding device 31, wherein the second grinding device 31 is mainly used to complete the grinding operation of at least a portion of the silicon rod 91 (such as performing grinding operations including rough grinding and fine grinding on the four sides of the square rod until the accuracy meets the requirements, etc.).

[0193] The structures associated with the grinding station 2 and the grinding station 3 are both arranged on the workbench 1 or arranged adjacent to the workbench 1. For example, the edge skin removal device 7 associated with the grinding station 2 is arranged on the workbench 1, and the edge skin collection device 8 associated with the grinding station 2 can be arranged near the workbench 1.

[0194] In a possible embodiment, the equipment body also includes a loading and unloading device 4, which is mainly used to load silicon rods in the form of round rods, semi-finished square rods (such as round rods after a pair of side skins are removed), square rods, etc. into the opening and grinding machine 100 or unload / remove them from the opening and grinding machine 100.

[0195] In a possible implementation, the equipment body further includes a clamping and transporting device 5 , which is mainly used to transport the silicon rods 91 between various workstations or within a certain workstation to ensure the sustainability of the operation of the grinding and polishing machine 100 .

Complete machine protection

[0196] Main reference Figure 3 and Figure 4In a possible implementation, the integrated opening and grinding machine 100 of the present invention, under the premise of ensuring that the functions of each component can be realized, forms a relatively closed working area for the whole machine through the positional relationship between the components and the configuration of the corresponding protective components, so that the working area of ​​the integrated opening and grinding machine is protected as a whole, and thus ensures that operations such as squaring and grinding of the silicon rod 91 can be carried out safely, stably and smoothly. As in the present example, the main body of the equipment forms a protective body by configuring a protective frame (such as a shell, a protective cover 61, etc.) as the basis of the first protective component for the corresponding components, and cooperates with other necessary components such as a power distribution cabinet 63, and the protective body of the integrated opening and grinding machine 100 constructs a relatively closed space (such as a roughly closed space enclosed along the circumference).

[0197] In a possible implementation, the edge skin collecting device 7, the cutting device, the first grinding device associated with the grinding station 2, and the second grinding device associated with the grinding station 3 can be located in the space, and thus the corresponding devices and operations corresponding to the devices can be effectively protected by the protective body. The edge skin collecting device 8 and the loading and unloading device 4 are placed on the outside of the whole machine corresponding to the protective body. Such a setting can facilitate docking with external equipment such as AGV and manual material collection.

[0198] As in this example, the overall structural layout is: the grinding station 2 and the grinding station 3 are arranged roughly side by side, and the loading and unloading device 4 for loading the round rods (or semi-finished rods) to be processed and unloading the square rods after processing (of course, they can also be semi-finished rods, such as part of the grinding operation is completed by other equipment other than the present invention) is located on the side of the two (the front side in the figure). The edge skin collection box 81 of the edge skin removal device 7 and the edge skin collection device 8 is located on the side where the grinding station 2 is located (the left side in the figure), and the power distribution cabinet 63 is located on the side where the grinding station 3 is located (the right side in the figure). After repeated adjustments by the inventor, it is proved that such a layout can effectively save the installation space required for the whole machine and the corresponding floor space. A protective cover 61 is added to each side of the whole machine, such as adding a protective cover only in a local position on the left side, front side and top side, to ensure that the grinding and grinding machine 100, such as the edge skin collection device 8, is not interfered with in the operation of transferring the edge skin material outward after collecting the edge skin material, the loading and unloading operation, the rotation of the clamping and transporting column, etc.

[0199] On this basis, an auxiliary protective structure (such as a separation fence 62, etc.) can be further added as a second protective component on the outside of the protective body to further ensure the reliability of the protection. As in this example, a separation fence is arranged at the position where movement will occur on the outside (such as the position corresponding to the edge skin removal device 7 and the position corresponding to the loading and unloading device 4), so as to effectively protect the area outside the working area involving movement, such as effectively preventing accidental injuries caused by personnel entering by mistake, leakage of the edge skin collection trolley, etc., thereby further ensuring the safety of the whole machine.

[0200] It can be understood that the specific form of the first / second protective components and their corresponding setting positions in this example are only an exemplary description, and those skilled in the art can flexibly adjust them, such as including but not limited to: setting the distribution cabinet as a suspended distribution cabinet, and configuring a protective cover at the position originally corresponding to the distribution cabinet; adding a reinforcing structure to the protective cover; adjusting the structural form of the protective cover; integrating a part or parts of the protective cover for the whole machine; changing the part of the isolation fence corresponding to preventing people from accidentally entering into a light curtain protection; adjusting the specific layout method of the corresponding layout area of ​​the isolation fence, such as changing the rectangular area into an arc area, etc.

[0201] For ease of explanation, the direction of the integrated grinding machine 100 is first set as follows: the direction in which the loading and unloading device 4 approaches / moves away from the clamping and transferring device in the horizontal plane along the radial direction is recorded as the Y direction, the direction perpendicular to the Y direction in the horizontal plane is recorded as the X direction (such as the direction in which a pair of cutting head assemblies of the cutting device approach / move away from each other, etc.), and the vertical direction perpendicular to the horizontal plane (such as the cutting feed direction, etc.) is recorded as the Z direction. The embodiment of the integrated grinding machine 100 of the present invention will be described below in combination with the direction setting and the accompanying drawings. [Loading and unloading device]

[0202] Main reference Figures 3 to 18 In a possible implementation, the loading and unloading device 4 of the grinding machine 100 mainly includes a loading and unloading turning assembly and a rotating clamp assembly 42. The loading and unloading device 4 can realize both automatic loading of silicon rods (such as round rods) and automatic unloading of silicon rods (such as square rods). The structure of the loading and unloading device 4 is described below by taking the loading operation as a loading operation for round rods and the unloading operation as an example for square rods.

[0203] In a possible embodiment, the loading and unloading flip assembly mainly includes a loading flip assembly 411 adapted to the round rod and a unloading flip assembly 432 adapted to the square rod. The loading and unloading flip assembly is mainly used to flip the silicon rod carried thereon so as to adjust the posture of the silicon rod and thus adapt to the loading and unloading process. Taking the loading flip assembly as an example, it is mainly used to flip the round rod from a horizontal state to a vertical state so that it can be adapted to the clamping and transporting device to ensure that the silicon rod can be smoothly docked with the grinding station 2. Among them, the loading and unloading flip assembly can be docked with external facilities such as AGV, truss manipulators and on-site facilities corresponding to manual loading and unloading operations. For example, in this example, the height of the loading and unloading flip platform is approximately 900mm. Taking the loading flip assembly 411 as an example, in addition to adjusting the posture of the silicon rod, the loading preparation of the round rod can also be realized (that is, it can be used as a waiting platform). Taking the unloading flip assembly 432 as an example, in addition to adjusting the posture of the silicon rod, the unloading detection of the square rod can also be realized.

[0204] In a possible embodiment, the loading and turning assembly 411 mainly includes a loading and turning hydraulic cylinder 4111, a loading and turning plate 4112, and a loading and receiving baffle 4113, wherein the power output end of the loading and turning hydraulic cylinder 4111 is connected to the loading and turning plate 4112. In this way, as the power output end of the loading and turning hydraulic cylinder 4111 gradually extends, the loading and turning hydraulic cylinder 4111 provides turning power and thus drives the loading and turning plate 4112 to turn over, thereby driving the round rod carried thereon to complete the turning, so that the round rod is gradually turned from a horizontal state to a vertical state that can be docked with the aforementioned grinding station 2, and the loading and receiving baffle 4113 is supported below the silicon rod when the silicon rod is in a vertical state. Exemplarily, the loading and turning assembly 4111 also includes a loading and turning induction switch 4115 for confirming that the turning is in place.

[0205] Similar to the loading flip assembly 411, in a possible implementation, the unloading flip assembly 432 mainly includes an unloading flip hydraulic cylinder 4121, an unloading flip plate 4122, and an unloading material receiving baffle 4123. The unloading flip hydraulic cylinder 4121 provides flipping power and thus drives the unloading flip plate 4122 to flip, thereby driving the square rod mounted thereon to complete flipping, so that the vertical state supported by the lower end surface of the square rod on the unloading material receiving baffle 4123 is gradually flipped to a horizontal state capable of docking with an AGV or the like.

[0206] In a possible implementation, the rotary clamp assembly 42 mainly includes a loading clamp assembly 421 adapted to the round rod, a discharging clamp assembly 422 adapted to the square rod, and a rotary mechanism 423 capable of switching the positions of the loading clamp assembly and the discharging clamp assembly. The reliably docking of the loading and unloading device with the clamping and transporting device can be achieved through the rotary mechanism 423. For example, the round rod that has been flipped to a vertical state in the loading flip assembly can be grabbed by the loading clamp assembly, and the square rod that has been processed and is in a vertical state in the clamping and transporting device can be grabbed by the discharging clamp assembly, and then the loading of the round rod and the unloading of the square rod can be achieved by rotating. Obviously, the grabbing of loading and unloading can also be performed at different times, that is, only the loading clamp assembly or the discharging clamp assembly is in a working state.

[0207] Reference Figure 5 In one possible implementation, the axis direction of the silicon rod in the loading and unloading flip assembly is substantially perpendicular to the Y direction, which is recorded as the X direction. Taking the loading operation as an example, after the silicon rod is delivered to the flip position in the horizontal direction to the left, it is flipped to a vertical state and clamped by the loading flip assembly, and then rotated 270° clockwise so that it can be docked with the clamping and transporting device.

[0208] In a possible embodiment, the feeding jaw assembly is mainly used to grab the round rod that has been turned over and placed on the round rod turning assembly, and complete the switching operation of the round rod from the waiting area to the processing area with the help of the rotating jaw assembly. In a possible embodiment, the feeding jaw assembly 421 mainly includes a plurality of pairs of feeding jaws (such as two pairs, i.e., 4 in this example) 4211 facing each other distributed along the axial direction of the silicon rod so as to grab the silicon rod at different positions, and the round rod is clamped by moving each pair of feeding jaws towards each other. Exemplarily, the surface of the feeding jaw close to the silicon rod is roughly a V-shaped surface so as to better clamp the round rod. For example, a feeding photoelectric switch can be installed on both sides of the width direction of the feeding jaw at a position approximately in the middle of the feeding jaw to detect whether a silicon rod is being fed. A feeding contact sensor can be installed at a middle position approximately in the middle of the feeding jaw to detect the clamping degree of the silicon rod.

[0209] In a possible embodiment, the feeding jaw assembly 421 includes a feeding jaw mounting base, and a feeding telescopic cylinder 4212 and a feeding linear guide 4213 are arranged on the upper jaw mounting base. The feeding telescopic cylinder drives a pair of feeding jaws to move closer to / away from each other through a feeding gear rack mechanism. Specifically, the power output shaft of the feeding telescopic cylinder is fixed to the first rack 42141 of the feeding gear rack mechanism, and the feeding telescopic cylinder drives the corresponding feeding jaws to perform telescopic movement along the linear guide through the feeding rack. At the same time, the first rack is connected to the second rack 42142 through a bevel gear 42143 and the second rack is fixedly connected to another feeding jaw, so that a pair of feeding jaws can be synchronously telescoped through a feeding telescopic cylinder to complete the clamping of the round bar. Exemplarily, a feeding jaw (such as in this example, the feeding jaw on the right side of a pair of feeding jaws) can be configured with a detection probe to detect the diameter, verticality, etc. of the round bar.

[0210] Obviously, the above-mentioned transmission method between a pair of feeding jaws is only an exemplary description, and technical personnel in this field can flexibly adjust it according to actual needs. For example, taking the current feeding gear rack mechanism as an example, the feeding telescopic cylinder can be replaced with a feeding telescopic motor and connected to the gear drive of the feeding gear rack mechanism.

[0211] In a possible embodiment, the unloading clamp assembly 422 is mainly used to grab the square rod on the clamping and transporting device and complete the switching operation of the square rod from the processing area to the unloading flip assembly with the help of a rotary mechanism. The unloading clamp assembly 422 mainly includes an unloading clamp mounting base, a pair of unloading clamps 4221, a first telescopic cylinder 4222, a second telescopic cylinder 4223 and two unloading linear guides corresponding to the movement direction of the unloading clamp driven by the first / second telescopic cylinder. A telescopic cylinder that can be telescopic in the horizontal direction (left and right) provides power to open / clamp a pair of unloading clamps, that is, under the drive of the first telescopic cylinder, a pair of unloading clamps can reliably grab the silicon rod by moving along the unloading linear guide. For example, the first telescopic cylinder and the pair of unloading clamps can adopt a driving connection method similar to or different from that corresponding to the pair of loading clamps mentioned above. The second telescopic cylinder that can be telescopic in the longitudinal direction can drive a pair of unloading clamps to move in the vertical direction so that the square rod can be grabbed at different heights.

[0212] In a possible embodiment, the blanking clamp is a plate-like structure, and the inner side of the plate-like structure (the side where the two blanking clamps are close to each other) is provided with a blanking support structure that can directly contact the square rod. If the blanking support structure includes a plurality of strip structures, then a blanking clamping space that can be well adapted to the square rod can be formed.

[0213] In a possible embodiment, the aforementioned loading and unloading turning assembly and loading and unloading manipulator assembly constitute a loading assembly 41 in the loading and unloading device capable of loading round bars into the grinding machine, and the aforementioned unloading and unloading turning assembly, unloading manipulator assembly and base assembly constitute a unloading assembly in the loading and unloading device capable of unloading square bars from the grinding machine. On this basis, the loading and unloading device includes a base assembly 4234 that carries a rotary clamping jaw assembly including a rotary clamping jaw assembly, so as to cooperate with the loading and unloading assembly to smoothly realize the corresponding loading and unloading operations.

[0214] In a possible embodiment, the base assembly 4234 mainly includes a Y-axis transmission assembly 42341 as a first transmission assembly and an X-axis transmission assembly 42342 as a second transmission assembly (perpendicular to the Y-axis, capable of realizing the overall movement of the rotary jaw assembly). The X-axis transmission assembly is disposed on the Y-axis transmission assembly 42341. The Y-axis transmission assembly 42341 can enable the rotary jaw assembly to move in a direction approaching / away from the clamping and transferring device, so it can be referred to as the loading and unloading direction.

[0215] In one possible embodiment, the X-axis transmission assembly 42342 includes an X-axis base, which is equipped with an X-axis moving motor. The X-axis moving motor drives the Y-axis base, the Y-axis transmission assembly including the rotating jaw assembly, to move as a whole relative to the Y-axis transmission assembly along the X direction through a screw nut mechanism.

[0216] Exemplarily, the loading and unloading turning assembly includes a loading and unloading turning base (such as a bracket, etc.), a turning plate and a loading and unloading conveying assembly, etc. are all arranged on the loading and unloading turning base, and the X-axis base is provided with a foot under the loading and unloading turning base to achieve support. Exemplarily, the foot is a height-adjustable foot, and the foot can also be changed to other supporting structures such as rollers.

[0217] In a possible implementation, the slewing mechanism 423 mainly includes a slewing frame 4231, a slewing base 4232, a slewing motor 4233 and a base assembly 4234. A slewing space is formed in the slewing frame, the slewing motor is in the slewing space and fixed to the bottom of the slewing frame, and the slewing motor is pivotally arranged on the slewing base to realize the overall slewing motion of the slewing frame.

[0218] In a possible embodiment, the base assembly 4234 mainly includes a Y-axis transmission assembly 42341 and an X-axis transmission assembly 42342 arranged on the Y-axis transmission assembly. The Y-axis transmission assembly 42341 can enable the rotary jaw assembly to move in a direction approaching / moving away from the clamping and transferring device, so it can be called the loading and unloading direction.

[0219] In one possible embodiment, the Y-axis transmission assembly 42341 includes a Y-axis base, which is equipped with a Y-axis moving motor. The Y-axis moving motor drives the X-axis transmission assembly and the rotating jaw assembly including the rotating jaw assembly to move along the Y direction through a screw nut mechanism, thereby driving the silicon rod carried on the rotating jaw assembly to accurately dock with the clamping and transfer device along the Y direction.

[0220] In a possible embodiment, the X-axis transmission assembly 42342 includes an X-axis base, which is equipped with an X-axis moving motor. The X-axis moving motor drives the Y-axis transmission assembly including the rotating jaw assembly through a screw nut mechanism to move the rotating jaw assembly as a whole relative to the Y-axis transmission assembly along the X direction.

[0221] The slewing base is connected to the nut in the screw nut mechanism in the X-axis transmission assembly, such as a screw nut seat 42321 is provided at the bottom of the slewing base, thereby realizing the movement of the slewing mechanism along the X direction. In addition, the slewing frame serves as a mounting carrier, and a pair of opposite surfaces thereof are provided with the aforementioned mounting structures such as linear guides, sliders, and upper / lower material clamps.

[0222] For example, the Y-axis base is provided with a water tray 42343 near the X-axis transmission assembly, which is mainly used to receive the water drops carried by the silicon rods. An adjustment washer 42344 is installed below the Y-axis base to support the slewing mechanism. The adjustment washer can also be changed to other forms of support structures such as footing.

[0223] In a possible embodiment, the loading and turning assembly 411 also includes a loading and locking assembly 4114, which is mainly used to ensure the stability of the round bar on the loading and turning table. In a possible embodiment, the loading and locking assembly 4114 mainly includes a telescopic cylinder 41141 as a locking drive component, a clamping block 41142, a tension spring 41143 and a pressing block 41144, and the power output shaft of the telescopic cylinder is connected to the clamping block, and the clamping block is arranged in a pivotable manner. Fig. 9 In the state of flipping preparation, the cylinder power output shaft is retracted, and the end of the clamping block is tightened by elastic parts such as tension springs, so that the clamping block rotates around the rotating axis and is in a vertical clamping state. Fig.10 When loading the round bar, the cylinder power output shaft extends and the clamping block is at the extreme position at the end. At this time, the pressing block presses the clamping block, making it unable to rotate and thus in a bent state to ensure safe and stable loading.

[0224] Obviously, the above structure is only an exemplary description of the feeding locking assembly, and those skilled in the art can adjust the structural form and locking principle of the feeding locking assembly according to actual needs. For example, the clamping block can be directly arranged on the feeding flip assembly in a vertically telescopic manner, and the clamping block can be replaced with a cover structure that can adapt to all or part of the end of the round rod.

[0225] In a possible embodiment, the loading assembly includes a loading conveying assembly 431, which is mainly used to achieve the arrival at the loading flipping position in the horizontal plane. As in this example, the loading conveying assembly 431 mainly includes a loading drive motor 4311 and a roller group 4312, and the roller group includes two rows of rollers with conical surfaces. If the loading drive motor is a double-output shaft drive motor, the double-output shaft drive motor drives the two rows of roller groups to roll along the loading direction respectively through a chain drive, and the surface of the silicon rod contacts the conical surface of the roller, thereby realizing the horizontal conveyance of the silicon rod through the synchronous rotation of the two rows of rollers. Obviously, the double-output shaft drive motor is only a preferred embodiment, and a loading drive motor can also be configured for each of the two rows of roller groups.

[0226] In a possible embodiment, similar to the loading and conveying assembly, the unloading assembly in the unloading and loading device includes an unloading and conveying assembly 432, which is mainly used to convey the silicon rods along the X direction to the unloading position where the silicon rods can be separated from the grinding machine. As in this example, the unloading and conveying assembly 432 mainly includes an unloading and conveying motor 4321 and an unloading and conveying conveyor belt 4322. The unloading and conveying motor drives the sprocket to drive the unloading and conveying chain to transmit, and the square rods placed above the unloading and conveying conveyor belt are thus conveyed to the unloading position. Exemplarily, the unloading assembly is provided with an unloading photoelectric switch 4323 at a position corresponding to the upper part of the unloading and conveying conveyor belt to detect whether there are square rods being unloaded on the current unloading and conveying conveyor. Exemplarily, side baffles 4324 can be respectively provided on both sides of the unloading and conveying assembly to protect the silicon rods during the incoming materials and the conveying process.

[0227] Based on the above structure, the process corresponding to the loading and unloading device in the integrated grinding machine of the present invention mainly includes the following steps:

[0228] Loading-Waiting: The round bars to be processed are placed in the waiting area of ​​the loading and turning assembly through AGV, manual operation, etc.

[0229] Loading-retrieving: The rotating frame rotates relative to the Y-axis base, thereby rotating the loading jaw assembly to a position corresponding to the loading flip assembly. When the round bar is flipped into place by the loading flip assembly, the two pairs of loading jaws of the loading jaw assembly can move close to each other to clamp the round bar to be processed, thereby completing the retrieving.

[0230] Loading-clamping: The X-axis transmission assembly in the rotary mechanism returns to the specified position, and the rotary frame rotates 90° counterclockwise, so that the round bar clamped between the two pairs of loading jaws can be rotated to a position that can be aligned with the clamping and transporting device. At this time, the Y-axis transmission assembly transports the round bar to the specified position, so that it can dock with the clamping station of the clamping and transporting device. The clamping and transporting device clamps the round bar, and the loading is completed. After the loading is completed, the lead screw of the Y-axis transmission assembly is reversed, and the rotary frame can exit the working area of ​​the grinding machine.

[0231] Unloading and picking up: During the period of squaring, chamfering, grinding and other operations on the loaded silicon rods at the grinding station, as well as during the period of rough and fine grinding at the grinding station, the material can be waited for in the loading flip assembly. At this time, the rotating frame rotates 90° clockwise to pick up the next round rod. After the operations corresponding to the grinding station and the grinding station are completed, the rotating frame rotates 90° clockwise as a whole, so that the unloading clamping jaw assembly corresponding to the square rod can be aligned with the square rod processed after the operation is completed and mounted on the clamping and transporting device. At this time, the Y-axis transmission assembly pushes the unloading clamping jaw assembly to the specified position, so that it can dock with the clamping station of the clamping and transporting device, and the square rod can be grabbed at this time.

[0232] Unloading-dropping: After the grabbing is completed, the lead screw of the Y-axis transmission assembly is reversed to drive the rotating frame backward, and the rotating frame is rotated 90° counterclockwise so that the unloading clamp assembly is in a position to dock with the unloading flip assembly. In this way, the processed square rod can be transferred to the unloading flip assembly. At this time, the rotating frame can be rotated 180° counterclockwise, and the loading clamp assembly can dock with the loading flip assembly (the material waiting table of the loading flip assembly is aligned), and the loading and unloading device can be randomly in a state of preparing for the next loading and unloading. For example, the loading of new round rods can be completed through the loading conveying assembly and the Y-axis transmission assembly.

[0233] Unloading and flipping: Flip the unloading and flipping assembly 90° to switch the square bars to a horizontal position. The square bars mounted on the unloading and flipping assembly can be removed from the grinding machine through the unloading conveying assembly.

[0234] Of course, the above steps are only explained by taking a single type of loading and unloading operation as an example. Obviously, the loading and unloading operations can be completed simultaneously by the loading jaw assembly and the unloading jaw assembly on the rotary mechanism.

Clamping and transfer device

[0235] Main reference Figures 19 to 27In a possible implementation, the clamping and transporting device 5 mainly includes a rotating table 52 rotatably mounted on the aforementioned workbench 1 and a clamping and transporting column 53 disposed on the rotating table 52. In this example, the clamping and transporting column 53 has a pair of opposite sides, each of which is provided with a slide assembly 56, a clamping head assembly 57 and a hemming assembly 58, so as to be responsible for the clamping and transport of the silicon rod between various positions (opening and grinding stations, grinding stations, and loading / unloading stations corresponding to loading and unloading devices). Exemplarily, the rotating table 52 can be rotated by means of gear transmission.

[0236] In a possible embodiment, the clamping and transporting column 53 is installed on the rotating worktable 52 so that the two side surfaces can be in different positions as the rotating worktable 52 rotates. For example, in this example, with the position corresponding to the loading station in the loading and unloading device as the starting point of 0° and the loading station as the origin, the clamping and transporting column 53 can be rotated 90° to reach the grinding station, such as performing the first squaring operation (such as removing a pair of edge skins) on the round rod. After the cutting step in the first squaring operation is completed, the edge skin assembly is used to clamp the pair of edge skin materials generated by squaring. After the edge skin materials are clamped, the two chucks in the clamping head assembly (such as the lower chuck is the fixed chuck and the upper chuck is the dynamic chuck) are synchronously rotated 90° to adjust the circumferential posture of the silicon rod. After the rotation, the round rod with a pair of edge skins removed can be squared for the second time (i.e., removing another pair of edge skins). Similar to the first squaring operation, after the cutting process in the second squaring operation is completed, the edge skin assembly is used to clamp the other pair of edge skin materials. After the edge skin materials are clamped, the two clamps in the clamping head assembly are synchronously rotated 45°, and on this basis, the first chamfering operation for one pair of edges can be performed through the first grinding device or cutting device. After the first chamfering is completed, the two clamps in the clamping head assembly are synchronously rotated 90°, and on this basis, the first chamfering operation for another pair of edges can be performed through the first grinding device or cutting device, and the processing operation corresponding to the grinding station is completed. The rotating worktable of the clamping and transporting column is rotated 180° so that the silicon rod (squaring is completed and edge grinding is completed) clamped on the clamping and transporting column reaches a position where it can dock with the grinding station. At this time, the posture of the silicon rod can be switched with the help of the clamping head assembly, so that the four sides and four edges of the silicon rod can be ground including rough grinding and fine grinding until the accuracy reaches the standard. After the grinding operation is completed, the clamping transfer column is rotated 90 degrees to reach the unloading station corresponding to the loading and unloading device. At this time, the unloading operation of the square bar can be completed by cooperating with the aforementioned unloading component.

[0237] It can be understood that the aforementioned operations of removing two pairs of side skins and grinding chamfers at the grinding station, the rough and fine grinding of two pairs of side surfaces and chamfers at the second station, and the specific operation sequence are only an exemplary description, and technical personnel in this field can flexibly adjust them according to actual needs, such as including but not limited to: chamfering operations by wire cutting in the grinding station; squaring the remaining part of the silicon rod with one pair of side skins removed in the grinding station (only one pair of side skins is removed in the grinding station); the grinding operation is first performed in the grinding station and then returns to the grinding station (if it can return again to continue the grinding work).

[0238] In a possible embodiment, the slide assembly 56 mainly includes a slide support, a slide linear guide, a slide motor and a slide connecting plate 561, wherein the slide support is arranged on the side (clamping surface) of the clamping transfer column, a pair of slide linear guides are installed on the slide support in the vertical direction, the slide connecting plate is movably arranged on the slide linear guide, and the slide motor is used to drive the sliding connecting plate to move along the slide linear guide. Exemplarily, the slide motor drives the lead screw in the lead screw nut mechanism to rotate, and the nut in the lead screw nut mechanism fixed to the slide connecting plate moves along the slide linear guide, thereby driving the slide connecting plate to move in the vertical direction.

[0239] In a possible embodiment, the clamping head assembly 57 includes a first clamping head 571 located at the top and a second clamping head 572 located at the bottom, wherein the first clamping head 571 is arranged on a first clamping head seat 5711, and the first clamping head seat is arranged on the slide connecting plate 561, so that the first clamping head 571 (movable clamping head) can move along the vertical direction with respect to the slide connecting plate 561. The second clamping head 572 (fixed clamping head) is arranged on a second clamping head seat 5721, and the second clamping head seat is fixedly arranged on the side of the clamping and transporting column, so as to support the silicon rod while clamping the silicon rod through cooperation with the moving clamping head.

[0240] In this way, the clamping and loosening operations of silicon rods of different specifications (lengths) can be achieved through the cooperation between the movable clamp that can move in the vertical direction and the fixed clamp that is located below the movable clamp and has a relatively fixed position in the vertical direction.

[0241] At the same time, the movable chuck and the fixed chuck are respectively configured with a movable chuck rotating motor and a fixed chuck rotating motor, which are mainly used to realize the rotation of the silicon rod. If it is necessary to grind different (pairs) of sides of the silicon rod through the third station, the movable chuck rotating motor and the fixed chuck rotating motor of the clamping head assembly corresponding to the third station can be used to rotate the silicon rod from a state in which one pair of sides are aligned with the coarse / fine grinding wheel to a state in which the other pair of sides are aligned with the coarse / fine grinding wheel.

[0242] In actual processing, the end face of the silicon rod is not completely perpendicular to the axis of the silicon rod as in an ideal state. In addition, the silicon rod may also tilt to a certain extent during the loading and clamping process. Therefore, in a possible implementation, the fixed clamping head is a floating clamping head to compensate for the non-verticality of the end face of the silicon rod.

[0243] Exemplarily, a fixed chuck reducer and a fixed chuck bearing box are arranged between the fixed chuck rotating motor and the floating chuck. The floating chuck mainly includes a housing, an elastic diaphragm and a floating ball, wherein the housing includes an inner housing connected to the bearing box and an outer housing capable of contacting the end face of the silicon rod, and the diaphragm is respectively connected to the inner housing and the outer housing so as to allow a certain amount of offset between the inner housing and the outer housing. The floating ball is accommodated in the middle of the diaphragm of the annular structure. Through the movement of the floating ball in the floating ball seat arranged on the inner and outer housings, it is expected that the outer housing can be tilted in any direction relative to the inner housing to generate a certain amount of floating, thereby compensating for the non-verticality of the end face of the silicon rod.

[0244] It can be understood that the above-mentioned fixed clamping head is a floating clamping head and the specific structural form of the floating clamping head is only an exemplary description. For example, those skilled in the art can adopt other forms of floating clamping heads according to actual needs, or adjust the dynamic clamping head to a clamping head with a circumferential buffering function.

[0245] In a possible implementation, the edge-supporting skin assembly 58 mainly includes an edge-supporting skin support 581, an edge-supporting skin cylinder 582, an edge-supporting skin linear guide 583, a support bracket 584, and a support assembly 585. The edge-supporting skin support is fixedly connected to or integrally formed with the aforementioned first clamping head seat 5711 so that the edge-supporting skin assembly is fixedly arranged on the aforementioned slide seat support 561, and the edge-supporting skin cylinder and the edge-supporting skin linear guide are both arranged on the edge-supporting skin support. Exemplarily, the edge-supporting skin cylinder is a rodless cylinder, which is connected to the support bracket, so that the edge-supporting skin cylinder drives the support bracket to move up and down along the direction of the edge-supporting skin linear guide, so that the support assembly can be tightly abutted against the end of the edge skin.

[0246] In a possible implementation, the support bracket includes two support sub-brackets, and the two support sub-brackets are connected via a support skin connection structure. The rodless cylinder is arranged on the support skin support and is connected to the power output end and the support skin connection structure. A support component is arranged on each support sub-bracket to ensure that a pair of side skins can be supported at the same time. The support component 585 includes a side skin support mounting base and a side skin support structure 586 arranged on the side skin support mounting base. Exemplarily, two side skin support mounting structures are arranged on each side skin support mounting base, and the side skin support mounting structure is a columnar body. In this way, the reliability of the side skin support can be ensured by a multi-point abutment method. Obviously, those skilled in the art can select the specific structural form, number, etc. of the side skin support mounting structure according to actual needs.

[0247] Exemplarily, the side skin supporting and mounting base includes a first side skin supporting and mounting portion and a second side skin supporting and mounting portion, the side skin supporting structure is arranged on the first side skin supporting and mounting portion, and the first side skin supporting and mounting portion is fixed to the supporting bracket through the second side skin supporting and mounting portion. For example, the second side skin supporting and mounting portion includes two L-shaped mounting frames, two columns are arranged between the two L-shaped mounting frames, the transverse portion of the L-shaped mounting frame is fixedly arranged on the first side skin supporting and mounting portion, and the vertical portion of the L-shaped mounting frame is fixedly connected to the outer side of the side skin clamping bracket. Obviously, those skilled in the art can select the specific structural form, number, etc. of the side skin supporting and mounting base according to actual needs.

[0248] Based on this, when the silicon rod is squaring, the edge skin supporting assembly supports the edge skin removed from the silicon rod, thereby protecting the edge skin, such as effectively preventing the edge skin on both sides of the silicon rod from tilting or falling.

[0249] It can be seen that the operation process of the silicon rod during the clamping operation realized by the clamping operation device is as follows:

[0250] After the silicon rod is transported to the processing area of ​​the grinding machine by the loading assembly of the loading and unloading device, the silicon rod to be processed is transported to the fixed clamp of the clamping and transporting device through the cooperation of the loading conveying assembly (transporting to the clamping position), the loading clamping claw assembly (clamping by the claw) and the loading flipping assembly (flipping the silicon rod in the clamping state), and then the moving clamp moves downward to clamp the silicon rod together with the fixed clamp. At this time, the loading assembly can be moved out of the processing area along the Y direction to avoid other operations.

Cutting device

[0251] Main reference Figures 28 to 34In a possible embodiment, the grinding station is equipped with a cutting device 21. The cutting device mainly includes an edge skin support component 22, a cutting feed component 23, a cutting head component 24 and a cutting column 25. Among them, the cutting feed component is arranged on the cutting column to drive the cutting section between the cutting head components to cut the silicon rod and generate edge skin. During the cutting operation, the edge skin support component abuts against the position corresponding to the edge skin at the bottom of the silicon rod, so as to stably support the edge skin generated by cutting at the cutting station through cooperation with the aforementioned edge skin support component.

[0252] In a possible implementation, the grinding station further includes a first grinding device 26. To match it, the cutting device is also equipped with a balancing cylinder assembly 27. The reason why the balancing cylinder assembly is equipped for the grinding station is that the first grinding device needs to be raised and lowered quickly during operation, while the cutting device is raised and lowered slowly during operation. Since the grinding station includes both the first grinding device and the cutting device, by configuring a balancing cylinder for the first grinding device, the deadweight of the first grinding device during use can be balanced, so that good dynamic performance can be achieved.

[0253] In a possible embodiment, the balancing cylinder assembly 27 mainly includes a balancing cylinder 271 and a balancing cylinder bracket. The balancing cylinder bracket mainly includes a sprocket bracket 272 arranged on the cutting column, a sprocket 273 installed on the sprocket bracket, and a plate chain 274 matched with the sprocket. Exemplarily, the plate chain uses the sprocket to support the reversal and is connected to the balancing block on the back side of the horizontal cutting feed lifting slide. As in the present invention, the cutting head assembly of the grinding station is also provided with a first grinding device for grinding chamfers. Therefore, the balancing cylinder assembly can be used to balance the weight of the cutting device and the first grinding device in the grinding station. Compared with the cutting operation, the feeding speed of the grinding operation is relatively large. Since there is no need to overcome the dead weight of the cutting device and the first grinding device in the reciprocating grinding operation, the service life of the vertical feed assembly can be extended. If the balancing cylinder is fixed on the balancing cylinder bracket, the balancing cylinder bracket is fixed to the cutting column and is located in the middle area between the two side portions of the cutting column. For example, a balance reserved space 275 is processed on the back of the cutting column (the side away from the cutting head assembly), and the balance cylinder is accommodated in the balance reserved space. A part of the sprocket bracket (such as the first part) is arranged on the top of the cutting column and the other part (such as the second part) is arranged in the balance reserved space. A reserved hole is opened on the top of the cutting column, and a plate chain matched with a sprocket mounted on the sprocket bracket is formed by passing through the reserved hole to form a balance cylinder assembly. As in this example, the first part is arranged obliquely at the top of the cutting column.

[0254] It can be seen that compared with the method of arranging the balancing cylinder assembly 27 on the outside of the cutting column, the balancing cylinder assembly of the present invention effectively saves space while ensuring that it can achieve the dynamic balancing function.

[0255] It can be understood that setting a part of the structure of the balancing cylinder assembly in the reserved space on the back side of the cutting column is only an exemplary description, and those skilled in the art can flexibly adjust it according to actual needs, such as accommodating a part of the balancing cylinder in the reserved space (such as partially protruding), accommodating the part above the balancing cylinder assembly in the reserved space, setting the reserved space on the other two sides of the cutting column or directly forming it inside the cutting column, etc.

[0256] In a possible implementation, the side skin support assembly 22 mainly includes a side skin support cylinder 221, a side skin support frame 222, a top side skin assembly 223 and a mold changing block 224. The side skin support cylinder drives the screw of the side skin support screw nut mechanism arranged on the basic workbench to rotate, and the nut of the side skin support screw nut mechanism is connected to the top side skin assembly through the side skin support frame, and the bottom end of the nut can slide in the side skin support linear slide rail also arranged on the basic workbench. The side skin support assembly is mainly used to support the side skin generated after cutting. The mold changing block is mainly used to ensure that the top side skin assembly can support the side skins of silicon rods of different specifications.

[0257] In a possible embodiment, the edge skin support frame includes a lower edge skin support frame base and a first edge skin support frame and a second edge skin support frame arranged on the edge skin support frame base and corresponding to a pair of edge skins for double cutting operation, and two top edge skin assemblies corresponding to one of the edge skins are respectively arranged on the first edge skin support frame and the second edge skin support frame. A change block is respectively arranged above the first edge skin support frame and the second edge skin support frame.

[0258] Based on the above structure, under the push of the side skin support cylinder, the top side skin assembly can move along the direction of the linear guide rail. On this basis, the side skin support frame is equipped with a side skin support limiting structure 229, which is mainly used to ensure the accurate positioning of the top side skin assembly when moving along the linear guide rail.

[0259] In a possible embodiment, the top edge skin assembly 224 mainly includes a top edge skin cylinder 225 and a top edge skin rod 226. When the silicon rod is cut and the edge skin is generated, the top edge skin cylinder drives the top edge skin rod to move upward, thereby pushing the edge skin upward to lift the edge skin. Afterwards, the edge skin unloading device can move the edge skin out of the cutting area.

[0260] Exemplarily, the top side skin assembly also includes a side skin rod guide sleeve 227 and a side skin rod pad 228, wherein the top side skin rod guide sleeve is mainly used to guide the side skin rod to move along the Z direction, and the side skin rod pad is arranged at the end of the top side skin rod close to the silicon rod, so as to directly contact the side skin of the silicon rod during the top side skin operation. For example, the area of ​​the side skin rod pad is usually larger than the cross-sectional area of ​​the side skin rod to ensure the stability of the operation. Exemplarily, two top side skin assemblies are configured for the side skin on each side.

[0261] As in this example, there is a mounting flange below the top side skin rod guide sleeve, the first / second side skin support frame includes two side skin support brackets corresponding to the two top side skin components, a side skin support connecting frame is arranged between the two side skin support brackets, and the guide sleeve is arranged on the side skin support connecting frame through the mounting flange and thus is arranged on the side skin support frame.

[0262] It can be understood that the structure of the above-mentioned top side skin assembly is only an exemplary description. Those skilled in the art can adjust the structure of the top side skin assembly according to actual needs, such as setting the surface of the pad to a curved surface, integrating the side skin rod guide sleeve and protective sleeve, etc.

[0263] In a possible implementation, the mold changing block 224 is provided with mounting positions that can adapt to silicon rods of different specifications. By selecting different mounting positions and installing corresponding top side skin components thereon, the side skins of silicon rods of different specifications can be supported.

[0264] Exemplarily, two groups of mounting holes 2241 are provided on the upper side of the mold changing block 224, and one group of mounting holes is provided on the lower side. When the upper side of the mold changing block is facing upward, any one of the two groups of mounting holes can be selected. If the lower group of mounting holes needs to be selected, the mold changing block is first adjusted up and down and reinstalled on the edge skin support frame, and then the group of mounting holes originally located at the lower side can be selected for installation.

[0265] It can be seen that the operation process of the silicon rod during cutting is realized by the edge skin support assembly as follows:

[0266] Cutting and transfer: After the silicon rod is loaded by the loading assembly in the loading and unloading device, it is transported to the clamping and operating device, clamped by the clamping head assembly of the clamping and operating device, and rotated to the cutting area corresponding to the cutting device in the grinding station through the rotation of the clamping and transferring column.

[0267] Tightening the side skin: Before the cutting operation begins, the side skin supporting cylinder drives the side skin assembly to move to the position corresponding to the side skin under the silicon rod. Driven by the side skin supporting cylinder, the side skin rod (the side skin pad) extends to contact the lower end surface of the side skin of the silicon rod and tighten it.

[0268] At this point, the cutting device can start cutting the silicon rod. After the cutting is completed, the generated edge skin is transferred from the edge skin unloading device to the edge skin collecting device, and the edge skin support assembly returns to its original position (avoidance). That is: during and after the cutting operation (until the edge skin clamping assembly of the edge skin unloading device clamps the edge skin), the top edge skin assembly maintains support for the lower end surface of the edge skin. It can be understood that after the cutting is completed, the diamond wire cutting segment should be located exactly in the gap between the fixed clamping head below the clamping head assembly and the top edge skin assembly (top edge skin rod) of the edge skin support assembly.

[0269] In a possible implementation, the cutting feed assembly mainly includes a vertical cutting feed assembly 231 and a transverse cutting feed assembly 232, and the cutting feed assembly is mainly used to realize the linear feeding movement of the cutting head assembly along the transverse and vertical directions.

[0270] In a possible embodiment, the vertical cutting feed assembly 231 mainly includes a vertical cutting feed motor 2311, a vertical cutting linear guide rail 2312 and a vertical cutting lead screw nut mechanism 2313 arranged on the first / second cutting column, the vertical cutting feed motor is connected to the lead screw of the vertical cutting lead screw nut mechanism, the nut of the vertical cutting lead screw nut mechanism is connected to the transverse cutting feed assembly, and the nut of the vertical cutting lead screw nut mechanism can slide along the vertical cutting linear guide rail. In addition, the vertical feed assembly is also slidably connected to the two linear guide rails arranged on the cutting column, so that under the drive of the vertical cutting feed motor and under the guidance of the vertical cutting linear guide rail, the vertical feed assembly can drive the transverse feed assembly to realize its movement along the Z direction, and further enable the cutting head assembly arranged on the transverse feed assembly to feed the cut silicon rod vertically downward.

[0271] Exemplarily, a detection component such as a proximity switch is provided at the bottom of the first / second cutting device so that the cutting can be stopped accurately after the cutting is in place (completed). A buffer pad is also provided near the bottom of the cutting device to abut against the bottom of the transverse cutting feed assembly to ensure that the transverse cutting feed assembly can stably fall to the lowest position.

[0272] In a possible implementation, the transverse cutting feed assembly 232 mainly includes a transverse cutting feed lifting slide 2321, a transverse cutting feed motor 2322 disposed on the transverse cutting feed lifting slide, and a transverse cutting lead screw nut mechanism 2323. The transverse cutting lifting slide is slidably connected to the aforementioned vertical cutting feed assembly, so that the transverse cutting lifting slide and the cutting machine head assembly mounted thereon are driven to move in the vertical direction by the vertical cutting feed motor.

[0273] In a possible embodiment, the transverse cutting feed motor is connected to the screw of the transverse cutting screw nut mechanism and the rotation directions of the two ends of the screw are opposite. The two nuts of the transverse cutting screw nut mechanism are respectively connected to a pair of cutting wheels that form a diamond wire cutting segment (two pairs of cutting wheels, a diamond wire cutting segment is formed between a pair of cutting wheels corresponding to one nut), and the nuts of the transverse cutting screw nut mechanism can slide along a linear guide rail provided on the cutting machine head assembly. In this way, under the drive of the transverse cutting feed motor, the opening and closing between the two pairs of cutting wheels can be achieved by a transverse cutting feed motor, so that silicon rods of different specifications (radial dimensions) can be double-wire cut (producing a pair of edge skins at a time). In addition, the transverse cutting feed assembly is also provided with a transverse cutting feed limit structure 2324 to ensure the proximity between the two pairs of cutting wheels.

[0274] In a possible embodiment, the cutting machine head assembly 24 includes a cutting wheel seat and a pair of cutting wheel assemblies 241 and a pair of tension wheel assemblies 242 arranged on the cutting wheel seat, each cutting wheel assembly includes a cutting wheel, and the cutting wheel assembly and the tension wheel assembly located on the same side correspond to a rotation direction of the lead screw in the aforementioned transverse cutting feed assembly. Among them, the cutting wheel assembly corresponding to the same annular cutting wire 243 (annular diamond wire) is equipped with a cutting wheel motor to provide the rotational cutting power required for the annular cutting wire, and the tension wheel assembly adjusts the tension of the annular diamond wire through a tension swing rod (under the support of the constant torque output by the tension motor). An annular diamond wire capable of cutting silicon rods is wound between the cutting wheel in the cutting wheel assembly and the cutting wheel of the tension wheel assembly. The silicon rod can be cut by the annular cutting wire between the two pairs of cutting wheel assemblies and the tension wheel assembly to produce a pair of edge skins. Compared with the traditional structure including a retracting and releasing wire assembly, a wire arrangement wheel assembly, a tension wheel assembly, and a wheel assembly, the method of annular wire cutting adopted in the present invention has advantages such as high efficiency and good stability. Moreover, due to the large number of components being reduced, the cost of related components is also saved, and the layout space of related components is saved. For example, in response to the aforementioned loading and unloading device and the balancing cylinder assembly, the structure of the whole machine can be made more compact.

[0275] The aforementioned vertical cutting feed assembly can drive the two ring-shaped diamond wires between the two pairs of cutting wheel assemblies to move vertically, thereby performing double-wire cutting operations on a pair of edge skins at the same time. The aforementioned transverse cutting feed assembly can realize the separation / closing of the two diamond wire cutting segments in the transverse direction, thereby being able to perform the aforementioned double-wire cutting operations on silicon rods of different specifications (radial dimensions).

[0276] In a possible embodiment, the cutting wheel assembly 241 mainly includes a cutting wheel motor 2411, a cutting wheel bearing box 2412 and a cutting wheel 2413. The cutting wheel motor drives the cutting wheel to realize the high-speed rotation of the annular diamond wire. The cutting wheel assembly and the tension wheel assembly are fixedly connected to the nut of the aforementioned screw nut mechanism through the cutting wheel seat 244, and the cutting wheel seat is slidably connected to the transverse cutting feed lifting slide. If the cutting wheel seat 244 includes a cutting wheel seat table 2441 and a cutting wheel seat slide 2442, the cutting wheel seat slide is fixedly connected to the nut of the transverse cutting screw nut mechanism and is slidably connected to the feed lifting slide of the aforementioned transverse cutting feed assembly.

[0277] In a possible implementation, the tension wheel assembly 242 mainly includes a tension wheel support 2421, a tension wheel motor 2422 disposed on the tension wheel support, a tension swing rod 2423, and a tension wheel 2424 (in the present invention, an annular cutting line 243 is supported between the tension wheel and the cutting wheel, so the tension wheel can also be called a cutting wheel). The tension wheel motor is connected to the tension swing rod, and the tension wheel is disposed on the tension swing rod and can swing with the swing of the tension swing rod. The tension wheel assembly is mainly used to adjust the tension of the annular cutting line during the cutting process, thereby ensuring that the cutting process can be carried out smoothly and stably.

[0278] It can be seen that the operation process of the cutting device corresponding to the grinding station is:

[0279] Waiting for loading: Before the silicon rod is transported to the grinding station, the cutting device rises vertically to the highest position on the vertical cutting feed assembly through the horizontal cutting feed assembly. The two pairs of cutting head assemblies arranged opposite to each other are separated horizontally to the required distance, and sufficient avoidance space is left for the clamping head assembly that clamps the silicon rod.

[0280] Equipment tool setting: The clamping and transfer device drives the silicon rod to rotate to the cutting area corresponding to the first station. The edge skin support assembly moves to the position corresponding to the edge skin of the silicon rod. The cutting device moves vertically downward for a certain distance to reach the cutting start position. The cutting wheels of the two sets of cutting wheel assemblies corresponding to the two edge skins of the silicon rod move toward each other laterally. The annular diamond wire between the two cutting wheels on the same side is aligned with the cutting position corresponding to the cutting start position, the two annular diamond wires between the two pairs of cutting wheels on different sides are parallel, and the distance between the two annular diamond wires corresponding to the loading waiting and equipment tool setting steps are pre-set.

[0281] Silicon rod squaring: The cutting wheel motor drives the annular diamond wire to move at high speed. The cutting device as a whole moves vertically downward along the sliding of the vertical cutting feed assembly of the cutting column along the horizontal cutting feed assembly to cut the silicon rod. A pair of edge skins will be cut off after each cutting. If the two cutting edges pass, the silicon rod can be squaring.

[0282] After cutting, the annular diamond wire on each side is located exactly in the gap between the floating clamping head (supported in the area near the middle of the silicon rod end face) and the edge skin support assembly on the corresponding side (supported in the area of ​​the silicon rod end face corresponding to the edge skin).

[0283] In a possible embodiment, a first grinding device installation space is formed inside the cutting wheel seat of the cutting device. At least a portion of the first grinding device described below is installed in the space. If the first grinding motor is exposed to the environment in the installed state, the first grinding head can be arranged in the space in a retractable manner. If the cutting wheel assembly is in a working state, the first grinding head retracts to avoid interference with the cutting operation. In the case where the first grinding head is required to operate, the first grinding head is extended to a position where it is not interfered with by the cutting wheel so that the silicon rod is ground by the rotation of the first grinding head. As in this example, the first grinding head is mainly used for grinding the edges of the silicon rod, and the edges of the silicon rod can also be processed by wire cutting, that is, by a cutting device. As in this example, the first grinding device installation space is located between the two cutting wheels on the same side and close to one of the cutting wheels (corresponding to the cutting wheel of the tension wheel assembly), and the axis of the first grinding head of the first grinding device is lower than the cutting wheel.

Edge skin removal device

[0284] Main reference Figures 35 to 43 In a possible embodiment, the edge skin removal device 7 includes two sets and is respectively arranged on two opposite surfaces of the cutting column of the grinding station. Each set of edge skin removal devices 7 can unload one of the edge skin materials generated by the aforementioned squaring operation, such as unloading the edge skin material generated by the grinding station to the edge skin collection device. In this way, through the cooperation of the two sets of edge skin removal devices 7, a pair of edge skin materials generated by the double-line cutting squaring operation can be unloaded to the edge skin collection device. The edge skin unloading device mainly includes an edge skin removal power component 71 and an edge skin clamping component. The edge skin clamping component is mainly used to clamp the edge skin. On this basis, through the vertical pivoting movement of the edge skin removal power component, the clamped edge skin is unloaded to the edge skin collection device in the original posture (vertical) pivoting movement.

[0285] In a possible embodiment, the edge skin removal power assembly 71 mainly includes an edge skin removal support frame 711, an edge skin removal cantilever assembly 712 and an edge skin removal shaft assembly 713, wherein the edge skin removal support frame 711 is arranged on the cutting column 25 of the grinding station, the edge skin removal cantilever assembly 712 includes a first edge skin removal cantilever group 7121 and a second edge skin removal cantilever group 7122, and the edge skin removal shaft assembly 713 includes a first edge skin removal shaft 7131, a second edge skin removal cantilever group 7132, and a first edge skin removal shaft assembly 7133. The second edge skin removal shaft 7132 and the third edge skin removal shaft 7133, wherein the first edge skin removal cantilever group 7121 can rotate relative to the edge skin removal support frame 711 through the first edge skin removal shaft 7131, the second edge skin removal cantilever group 7122 can rotate relative to the first edge skin removal cantilever group 7121 through the second edge skin removal shaft 7131, and the edge skin clamping assembly 72 can rotate relative to the second edge skin removal cantilever group 7122 through the third edge skin removal shaft 7133. The first edge skin removal cantilever group and the second edge skin removal cantilever group are hinged so that they can rotate freely.

[0286] As in this example, the first / second edge skin cantilever group includes two cantilevers arranged roughly in the horizontal direction, and the two cantilevers are connected to each other through a connecting structure such as a connecting rod. Obviously, this is only an exemplary description, and those skilled in the art can determine the specific structural form of the first / second edge skin cantilever group according to actual needs, such as a ring structure, a truss structure, a plate structure, etc., and the two can be the same or different.

[0287] In a possible embodiment, the first / second / third edge-skinning rotating shaft is respectively configured with the first / second / third edge-skinning power transmission mechanism to realize the rotation of the corresponding dimension. In this example, the first / second / third edge-skinning power transmission mechanism adopts a substantially similar structure. Taking the second edge-skinning power transmission mechanism configured on the second edge-skinning rotating shaft 7132 as an example, it includes an edge-skinning motor 71321, an edge-skinning reducer 71322 and an edge-skinning gear pair 71323, wherein the edge-skinning gear pair 71323 includes a driving gear 713231, a driven gear 713233 and a transition gear 713232 therebetween, the edge-skinning reducer is fixed to the cantilever located above the first edge-skinning cantilever group through an edge-skinning reducer support, the transition gear is fixed to the cantilever through a set of bearing assemblies, and the driven gear is fixed to the second edge-skinning rotating shaft. The second side-skinning rotating shaft is respectively provided with an upper bearing assembly 713241 and a lower bearing assembly 713242 at positions corresponding to the upper side and the lower side of the cantilever, and the second side-skinning rotating shaft can rotate freely in the upper bearing assembly and the lower bearing assembly.

[0288] Based on this structure, when the first edge skin removal cantilever group is in a fixed state, when the edge skin removal motor is working, the power of the edge skin removal motor will be sequentially transmitted to the driven gear by the driving gear and the transition gear, and finally the driven gear will drive the second edge skin removal shaft and the second edge skin removal cantilever group to rotate around the second edge skin removal shaft. Similarly, if the second edge skin removal cantilever group is in a fixed state, when the edge skin removal motor is working, the power of the edge skin removal motor will be sequentially transmitted to the driven gear by the driving gear and the transition gear, and finally the driven gear will drive the first edge skin removal shaft and the first edge skin removal cantilever group to rotate around the first edge skin removal shaft. Among them, the speed, angle and other parameters of the rotation can be achieved through the operating parameters of the edge skin removal motor, the number of gears included in the edge skin removal gear pair, and the meshing relationship.

[0289] It can be understood that the above-mentioned specific edge-skin power transmission mechanism and the first / second / third edge-skin power transmission mechanism have roughly the same structural form, which is only an exemplary description. Those skilled in the art can select the specific form of the first / second / third edge-skin power transmission mechanism according to actual needs. For example, the aforementioned gear pair can be changed to a gear with more stages, etc. The structural form, installation position, etc. of the first / second / third edge-skin power transmission mechanism can be the same or different.

[0290] In addition, it can be understood that the two edge skin removing cantilever assemblies and the three edge skin removing shaft assemblies are only an exemplary description. Those skilled in the art can adopt more edge skin removing cantilever assemblies or only one edge skin removing cantilever assembly according to actual needs.

[0291] In a specific example, the first edge skin removing cantilever assembly can rotate around the first edge skin removing rotation axis within a range of approximately 168.4°, the second edge skin removing cantilever assembly can rotate around the second edge skin removing rotation axis within a range of approximately 120.6°, and the edge skin clamping assembly 72 can rotate around the third edge skin removing rotation axis within a range of approximately 144.9°.

[0292] In a possible embodiment, the edge skin clamping assembly 72 mainly includes an edge skin clamping movable jaw 722, an edge skin clamping bracket 721 provided with an edge skin clamping linear guide 724, and an edge skin clamping fixed jaw 723. Among them, the edge skin clamping fixed jaw is located below the edge skin, and can give the lower end face of the edge skin an upward pushing force. Driven by an edge skin clamping driving component such as a rodless cylinder, the edge skin clamping movable jaw can move vertically along the edge skin clamping linear guide to support the upper end face of the edge skin from top to bottom, that is, give the upper end face of the edge skin a downward clamping force. In this way, the edge skin of silicon rods of different specifications (lengths) can be clamped by the cooperation of the edge skin clamping movable jaw and the edge skin clamping fixed jaw. For example, a buffer structure such as a polyurethane pad can be provided on the inner side of the lower edge skin clamping fixed jaw and / or the upper edge skin clamping movable jaw facing the end face of the edge skin.

[0293] It can be seen that in the present invention, the side skin generated on the silicon rod is reliably clamped by the cooperation of a pair of side skin clamping movable jaws. On this basis, in order to ensure that each program in the grinding machine can be carried out smoothly, it is necessary to carry out corresponding avoidance design for the structures that intersect in space.

[0294] As in the present example, the lower skin edge clamping fixed jaw has a fixed jaw protruding end (corresponding to a clamping surface) approximately in the middle, and such a setting is mainly adapted to the two pairs of top skin edge rods in the aforementioned skin edge support assembly. Specifically, a fixed jaw protruding end is located between the two pairs of top skin edge rods, so that the movement of the top skin edge and the movement of the skin edge clamping can be performed without interference. In addition, adapted to the structure of the protruding end of the fixed jaw for clamping the skin edge, a vertical reserved space is provided on the skin edge collection box of the skin edge collection device described below, so that the fixed jaw protruding end can place the skin edge in the skin edge collection box by moving from top to bottom along the reserved space.

[0295] As in this example, the upper edge skin clamping movable clamp has two symmetrical movable clamp protruding ends (corresponding to two clamping surfaces). Such a setting is mainly adapted to the two pairs of edge skin supporting structures in the aforementioned edge skin supporting assembly. Specifically, the two pairs of edge skin supporting structures are respectively located on the inner side of the movable clamp protruding ends on the corresponding sides, so that the edge skin supporting action and the edge skin clamping work can be carried out without interference.

[0296] In this way, the three clamping surfaces including the buffer structure have good compressibility, so the end surface of the edge skin can be stably clamped to prevent the edge skin from loosening or even falling during the clamping and moving process. Obviously, the buffer structure can also be added to only part of the three clamping surfaces, or the two buffer structures corresponding to the edge skin clamping moving jaws can be integrally formed.

[0297] Obviously, those skilled in the art can also flexibly adjust the structural form of the fixed / movable clamping jaws for the edge skin according to the implementation requirements, such as adjusting it according to the structure of the edge skin support assembly and the edge skin support assembly, or adopting other avoidable structural forms when the structures of the edge skin support assembly and the edge skin support assembly remain unchanged.

[0298] In a possible embodiment, the edge skin removal power assembly 71 also includes an edge skin removal adjustment assembly 714, which is mainly used to enable the structure including the edge skin removal cantilever assembly 712 and the edge skin removal shaft assembly 713 to move as a whole relative to the edge skin removal support frame 711, so that the edge skin material generated by the square opening can be better unloaded through the cooperation between the edge skin removal power assembly 71 and the edge skin removal clamping assembly 72. As in this example, the edge skin removal adjustment assembly 714 includes an edge skin removal adjustment motor 7141, an edge skin removal adjustment reducer 7142 and an edge skin removal adjustment lead screw nut mechanism 7143, the edge skin removal adjustment motor transmits power to the lead screw of the edge skin removal adjustment lead screw nut mechanism through the edge skin removal adjustment reducer, and the nut of the edge skin removal lead screw nut mechanism is fixedly connected to the first edge skin removal cantilever assembly of the edge skin removal cantilever assembly 712 through a nut connecting seat, thereby driving the structure including the edge skin removal cantilever assembly 712 and the edge skin removal shaft assembly 713 along the axis (vertical) of the lead screw. For example, in order to ensure the reliability of movement, a guide structure such as a linear guide rail for adjusting the edge skin can be set on the edge skin support frame 711.

[0299] Obviously, this structure is only an exemplary description of the edge skin adjustment component. Those skilled in the art can flexibly select the specific form of the edge skin adjustment component according to actual needs, such as a power cylinder (such as a rodless cylinder, etc.), other forms of linear modules, etc.

Side skin collection device

[0300] Main reference Figures 44 to 48 In a possible implementation, the edge skin collection device 8 mainly includes an edge skin collection box 81 and an edge skin collection trolley 82. The edge skin collection box is mainly responsible for receiving the edge skin materials unloaded from the grinding station by the edge skin collection device. The edge skin collection trolley is mainly used to unload the edge skin materials collected in the edge skin collection box. The edge skin collection trolley is not only suitable for manual unloading, but also can be connected to automated equipment such as AGV. In order to ensure the sustainability of the operation, each edge skin collection box should accommodate multiple pieces of edge skin. As in this example, the edge skin collection box 81 includes a box body and 12 pairs of storage areas 811 arranged on the box body so as to accommodate 12 pieces of edge skin. The edge skin collection box is located above the edge skin collection trolley.

[0301] In a possible implementation, the storage area 811 is provided with a vertical reserved space 812 at the position corresponding to the edge skin clamping fixed jaw of the edge skin clamping assembly of the aforementioned edge skin removing device. In this way, driven by the edge skin removing adjustment assembly, the edge skin clamping fixed jaw below the edge skin clamping assembly can freely move to a position close to the bottom in the vertical reserved space, thereby stably placing the edge skin in the storage area at the corresponding position. Exemplarily, a water collection structure such as an edge skin collection water collection box 813 can be added to the bottom and periphery of the edge skin collection box to collect waste water (including cutting fluid) carried on the edge skin, thereby ensuring the cleanliness of the working environment of the grinding machine to a certain extent.

[0302] In a possible embodiment, the edge skin collection device 8 also includes a positioning component 83, which includes a guide wheel 831 provided on the edge skin collection trolley and a guide V-shaped groove 832 configured on the workbench 1 and capable of matching with the guide wheel. In this way, when the AGV carrying the edge skin collection trolley approaches the workbench, the movement of the guide wheel along the guide V-shaped groove can play a role in rough positioning. Obviously, the combination of the guide wheel and the guide V-shaped groove is only an exemplary description of the positioning component, and those skilled in the art can flexibly adjust it according to actual conditions, such as the matching of the slider and the guide rail, the matching of the columnar structure and the groove, etc.

[0303] In a possible embodiment, the edge skin collection device 8 further includes an edge skin collection locking assembly 85. For example, when the edge skin collection trolley is required to perform unloading operation (such as when the edge skin collection box is full of edge skins), the edge skin collection locking assembly is in a loose state, and the edge skin collection trolley retreats to achieve unloading of the edge skin material. When the edge skin collection trolley is not required to perform unloading operation, the edge skin collection locking assembly is in a locked state to ensure that the edge skin collection device can be reliably docked with the aforementioned edge skin removal device.

[0304] In a possible implementation, a side skin collection in place detection component 84 is installed on the workbench to detect the position of the side skin collection trolley relative to the workbench. As in the present example, the side skin collection in place detection component is a rotary limit switch, which includes a switch body and a roller 842 pivotally arranged on the switch body 841. When the side skin collection trolley reaches the designated collection position, the roller rotation limit reaches the designated position and can provide signal feedback. Based on the signal feedback, the side skin collection locking component 85 can lock the side skin collection trolley. Obviously, the side skin collection in place detection component can also be any other reasonable form other than the rotary limit switch, such as a photoelectric sensor, a displacement sensor, a pressure sensor, etc.

[0305] In a possible implementation, the edge skin collection locking assembly 85 mainly includes a locking cylinder 851, and the power output shaft 852 of the locking cylinder can be extended and retracted along its axial direction. The output end of the power output shaft is provided with a rotating arm 853 to realize the rotation of the rotating arm relative to the power output shaft. Based on this structure, when there is no need to lock the edge skin collection trolley, the cylinder locking assembly is in a rotating vertical state. When the operating system receives the in-position signal feedback from the rotation limit switch, the power output shaft of the locking cylinder is first contracted and then the rotation is completed. The cylinder locking device is in a horizontal locking state. For example, in this example, the end of the rotating arm away from the power output end is provided with an extension end, and the edge skin collection trolley is fixed relative to the workbench by pressing the edge skin collection trolley with the extension end.

[0306] It is understandable that the above structure for realizing the locking / loosening of the side skin collection trolley relative to the workbench is only an exemplary description, and those skilled in the art can flexibly adjust it according to actual needs. For example, the locking / loosening state of the side skin collection trolley can be switched by applying / removing magnetic attraction, by adding a component that can be docked in a manner such as a snap-on / plug-in manner, etc.

[0307] Exemplarily, the second pair of storage areas includes three substantially identical groups, each group of storage areas includes four pairs of storage areas, and the four pairs of storage areas are distributed sequentially from the middle to the sides, and the structural forms of different pairs of storage areas may be the same or different. As in this example, each pair of storage areas encloses an area with a rectangular cross-sectional profile and each rectangular area is substantially the same. However, the heights of different pairs of storage areas are different. As in this example, the two pairs of storage areas in the middle position (inside) are roughly the same height, and the heights of the two pairs of storage areas on the outside are roughly equal but lower than the heights of the two pairs of storage areas on the inside.

[0308] It is understandable that those skilled in the art can determine the structural form, distribution position and the way of forming the edge skin collection box of each pair of storage areas according to actual needs (such as the specifications of silicon rods, the movement form of the edge skin removal device, etc.). For example, the storage areas can include one group, two groups or more than three groups, and each group of storage areas still includes four pairs of storage areas. For example, the heights of the four pairs of storage areas can be completely staggered (such as decreasing in sequence).

[0309] It can be seen that the operation process of unloading and collecting the side skins realized by the side skin removal device and the side skin collection device is as follows:

[0310] Edge skin clamping: After the silicon rod cutting operation is completed, the edge skin removal device is activated, and the edge skin clamping assembly can be moved in the vertical direction through the edge skin removal adjustment assembly. The edge skin clamping assembly can be moved close to the edge skin through the joint pivoting of the first / second edge skin removal cantilever assembly. Based on the combined movement of the two, the edge skin fixed clamping jaw can be moved to a position corresponding to the lower end surface of the edge skin. The edge skin moving clamping jaw is moved vertically to a position corresponding to the upper end surface of the edge skin, so that the edge skin clamping assembly can be adapted to silicon rods of different axial sizes (lengths). Based on this, the edge skin material generated by the cutting operation of the grinding station can be clamped by the cooperation of the edge skin clamping fixed clamping jaw and the edge skin clamping movable clamping jaw.

[0311] In this process, the fixed jaws for clamping the edge skin have a structure capable of avoiding the top edge skin component, and the movable jaws for clamping the edge skin have a structure capable of avoiding the supporting edge skin component. For example, when the edge skin material is clamped, the edge skin supporting component and the supporting edge skin component need to be avoided to ensure the operation of the edge skin removing device. For example, the top edge skin component in the edge skin supporting component is lowered, and then the edge skin supporting component is withdrawn to achieve avoidance. For example, the edge skin supporting structure of the supporting edge skin component is raised to achieve avoidance.

[0312] Edge skin separation: through the joint pivoting of the first / second edge skin removing cantilever assembly of the two sets of edge skin removing devices, a pair of edge skins produced by cutting are first opened along the radial direction of the edge skin material to separate the edge skin from the silicon rod.

[0313] Preferably, the edge skin and the silicon rod are first staggered to destroy the adsorption force between the edge skin and the silicon rod, and then the edge skin and the silicon rod are radially opened. For example, the edge skin and the silicon rod can be staggered in the axial direction by using the edge skin adjustment component or staggered in the width direction of the cutting surface by the joint pivoting of the first / second edge skin cantilever component.

[0314] Edge skin transfer: After the edge skin clamping assembly clamps the edge skin, the edge skin clamping assembly holding the edge skin is driven to the collection area corresponding to the edge skin collecting device (the position corresponding to the storage area of ​​the edge skin collection box) through the joint pivoting of the first / second edge skin taking cantilever assembly.

[0315] Edge skin collection: After the edge skin removal device reaches the collection area, the edge skin removal adjustment component drives the edge skin clamping fixed / movable clamping claw of the edge skin clamping component to move downward along the vertical reserved space corresponding to one of the pair of storage areas of the edge skin collection box to the storage position. Afterwards, the edge skin fixed / movable clamping claw of the edge skin clamping component is withdrawn horizontally through the joint pivoting of the first / second edge skin removal cantilever component, so that a pair of edge skins can be stored in the corresponding pair of storage areas, thereby completing the edge skin storage. Repeat this process until the storage area in the edge skin collection box is full of edge skin materials, then release the locking state of the edge skin collection trolley, and remove the edge skin materials collected in the storage area from the collection area by manual unloading or docking with automated equipment such as AGV. Obviously, the edge skin materials can also be removed at any time when all the storage areas are not fully filled with edge skins.

First grinding device

[0316] Main reference Figures 49 to 51 In a possible embodiment, the first grinding device 26 included in the aforementioned grinding station mainly includes a first grinding fixed seat 261, a first grinding electric cylinder 262, a first grinding feed slide 263, a first grinding spindle assembly 264 and a first grinding head assembly 265. The present invention mainly grinds (chamfers) two pairs of edges of the square bar after the edge skin is removed by a pair of first grinding devices arranged opposite to each other. Obviously, the first grinding device can also be used to grind the two pairs of side surfaces of the square bar, or both.

[0317] Still taking the example of using the first grinding device to grind two pairs of edges of the square rod, in particular, since the grinding station of the present invention also includes a cutting device, the edges of the square rod after the squaring operation are cut by a pair of parallel annular diamond wires and then ground.

[0318] In a possible implementation, a first grinding spindle linear guide is provided on the first grinding fixed seat that can move vertically / laterally with the cutting device, the first grinding spindle assembly is slidably provided on the first grinding spindle linear guide (a slider that cooperates with the first grinding linear guide is provided at the bottom of the first grinding feed slide), the first grinding electric cylinder is installed on the first grinding fixed seat and its power output end is connected to the first grinding feed slide. In this way, the feeding action of the first grinding spindle assembly along its axial direction (along the X direction) can be realized by the movement of the first grinding electric cylinder, and under the drive of the grinding electric cylinders of a pair of first grinding devices, the grinding head assemblies of the two first grinding devices can move toward each other, thereby grinding a pair of edges of the silicon rod on this basis.

[0319] In a possible implementation, the first grinding spindle assembly mainly includes a first grinding spindle shaft housing, a grinding spindle inserted into the first grinding spindle shaft housing, and a first grinding motor drivingly connected to the first grinding spindle to drive the first grinding spindle to rotate. A first grinding installation space is formed between the first grinding spindle shaft housing and a portion of the first grinding spindle close to the first grinding electric cylinder, and the first grinding motor is installed in this space, thereby realizing the internalization of the first grinding motor.

[0320] The first grinding motor is connected to the grinding spindle through a combined bearing, and the grinding spindle is connected to the aforementioned first grinding head assembly through a grinding wheel adapter. In this way, the built-in first grinding spindle motor provides power to make the first grinding spindle rotate, thereby driving the grinding head to rotate to perform grinding operations on the edges of the square rod.

[0321] In a possible implementation, a grinding spray component is provided on the first grinding head assembly so as to reduce the adhesion of silicon powder generated by grinding on the silicon rod by spraying and cleaning the silicon rod being ground. The first grinding spindle shaft box housing is arranged on the first grinding feed slide plate, and the first grinding feed slide plate is slidably connected with the aforementioned first grinding spindle linear guide rail. The lubricating oil pipe of the first grinding spindle linear guide rail provides protection and serves as the first grinding drag chain of its mounting carrier.

[0322] It can be seen that the operation process of grinding the edge of the silicon rod by the first grinding device of the grinding station is as follows:

[0323] Preparation: The edge skin support assembly of the cutting device is away from the clamping and transporting device to avoid the first grinding head assembly of the first grinding device from interfering with the edge skin support assembly when the first grinding device moves up and down. The first grinding head assemblies of the two first grinding devices are relatively separated in the horizontal direction by the corresponding first grinding cylinders, and the clamping and transporting device is rotated 45° so that a pair of edges of the square rod just correspond to the two first grinding head assemblies.

[0324] Edge grinding: The two first grinding head assemblies are rotated at high speed by the built-in first grinding motor, and the first grinding head assemblies are extended horizontally to the cutting area of ​​the grinding station by the first grinding cylinder. The first grinding device is driven to move back and forth vertically by the cutting device to grind a pair of edges of the square rod. After the grinding operation of a pair of edges is completed, the moving chuck and the fixed chuck of the clamping head assembly are rotated 90° at the same time, and the above movement is repeated to grind the other pair of edges of the square rod. For example, in order to better utilize the integrated function of the grinding station, the edges can be cut by the two annular diamond wires of the cutting device and then ground by the first grinding device.

Second grinding device

[0325] Main reference Figure 52 to Figure 58 In a possible implementation, the second grinding device 31 mainly includes a second grinding column 311, a second grinding head assembly 313, a composite shaft assembly 314, a composite shaft transmission assembly 315, a detection assembly 316, a second grinding feed assembly 317, and a nitrogen balance system 318. Among them, the second grinding head assembly mainly includes a rough grinding wheel and a fine grinding wheel, the second grinding feed assembly mainly drives the second grinding head assembly (as well as the composite shaft assembly and the composite shaft transmission assembly) to move horizontally / vertically, so as to grind the two pairs of side surfaces of silicon rods (square rods) of different specifications to the required processing requirements, the detection assembly is mainly used to determine the grinding amount, and the nitrogen balance system can be installed on the rear side of the second grinding column, mainly used to balance the weight of the second grinding head assembly.

[0326] In a possible implementation, the second grinding head assembly 313 mainly includes a fine grinding wheel 3131 and a rough grinding wheel 3132 arranged at the same station, and the fine grinding wheel and the rough grinding wheel are arranged concentrically at the same station. For example, in this example, the rough grinding wheel is freely accommodated in the reserved space formed inside the fine grinding wheel. In this example, a pair of second grinding head assemblies and a pair of detection assemblies are symmetrically arranged on two second grinding feed slides of the second grinding feed assembly (located on both sides of the silicon rod). In this way, the second grinding head assembly can realize fine grinding and rough grinding operations on the silicon rod at the same station. Among them, the rough grinding wheel is located on the radial inner side of the fine grinding wheel, which is only an exemplary description, and the positions of the two can also be swapped.

[0327] Exemplarily, the second grinding head assembly is also equipped with a square brush 3191, a spray device 3192 and an air gun device 3193, wherein the square brush is mainly used to prevent the random diffusion of water mist during the grinding operation with a lot of water mist, and to a certain extent also plays a role in flushing the residual silicon powder on the surface of the silicon rod after the grinding operation. The spray device is mainly used to clean the surface of the silicon rod by spraying, thereby reducing the adhesion of silicon powder on the surface of the silicon rod. The air gun device is mainly used to clean the surface of the silicon rod by jetting, thereby reducing the adhesion of silicon powder on the surface of the silicon rod.

[0328] In a possible embodiment, the composite shaft assembly 314 includes a first transmission shaft 3141 (sleeve) of a cylindrical structure, a second transmission shaft 3142 (inner shaft) accommodated in the cylindrical structure, and a second grinding motor 3143 that drives the first / second transmission shafts to rotate synchronously, wherein the sleeve is connected to the fine grinding wheel so as to drive the fine grinding wheel to be connected when the sleeve 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.

[0329] In a possible implementation, the composite shaft assembly further includes a composite shaft housing 3143, a second grinding installation space is formed between the composite shaft housing and the first transmission shaft, and a second grinding motor 3144 drivingly connected to the composite shaft formed by the first transmission shaft and the second transmission shaft is installed in this space, thereby realizing the built-in second grinding motor. Exemplarily, under the drive of the second grinding motor, the first transmission shaft and the second transmission shaft always rotate synchronously.

[0330] In a possible implementation, the composite shaft transmission assembly is mainly used to drive the inner shaft in the composite shaft assembly to perform telescopic movement along the axial direction of the sleeve, thereby ensuring that the rough grinding operation or the fine grinding operation can be achieved without interference.

[0331] In a possible embodiment, the composite shaft transmission assembly 315 is a camshaft transmission assembly, such as the camshaft transmission assembly mainly includes a composite shaft transmission base 3151, a composite shaft transmission motor 3152, a composite shaft transmission reducer 3153, a composite shaft transmission eccentric shaft 3154, and a composite shaft transmission bearing sleeve 3155. The composite shaft transmission motor and the composite shaft transmission reducer are located on the composite shaft transmission base, and the composite shaft transmission motor is connected to the composite shaft transmission eccentric shaft through the composite shaft transmission reducer to provide rotational power for the composite shaft transmission eccentric shaft, and the tail end of the composite shaft transmission eccentric shaft passes through the composite shaft transmission bearing sleeve to achieve coaxial transmission. The eccentric shaft can abut against the second transmission shaft in the composite shaft assembly. Exemplarily, a three-wire sensor for telescopic detection is installed on the composite shaft transmission base.

[0332] Based on the above structure, the composite shaft transmission motor drives the composite shaft transmission eccentric shaft to rotate through the composite shaft transmission reducer, and the inner shaft can be extended relative to the sleeve with the rotation of the composite shaft transmission eccentric shaft. In this way, when the silicon rod needs to be roughly ground, the inner shaft is retracted. When the silicon rod needs to be roughly ground, the inner shaft is extended.

[0333] Obviously, the above-mentioned camshaft transmission assembly is only an exemplary description of the composite shaft transmission assembly. Those skilled in the art may choose other ways to realize the retractable transmission connection according to actual needs, for example, direct drive of the power cylinder, combination of the motor and the screw nut mechanism, etc.

[0334] In a possible implementation, the detection assembly 316 mainly includes a probe housing 3161, a probe 3162, a probe bracket 3163 and a probe cylinder 3164. A group (such as 3 in this example) of probes are installed on the probe bracket, and the power output end of the probe cylinder is connected to the probe bracket to drive the probe to move along the X direction.

[0335] Exemplarily, the detection assembly also includes a detection plate and a bumper, wherein the detection plate is used to calibrate the probe, and the bumper is used to push open the front plate of the probe protective cover to avoid direct contact between the probe and the protective door, thereby effectively preventing the probe from being damaged.

[0336] A detection component is installed on each of the pair of second grinding devices. Based on this, the operation process of the detection component is roughly as follows: the probe cylinder pushes the probe to the surface of the silicon rod after cutting to detect the grinding quality. For example, the detection process can calculate the grinding amount corresponding to the rough grinding wheel, and the rough grinding wheel moves forward along the radial direction of the silicon rod to a distance that matches the grinding amount to perform rough grinding. After the rough grinding is completed, the detection component repeats the previous detection process to calculate the grinding amount of the fine grinding wheel, and the fine grinding wheel moves forward along the radial direction of the silicon rod to a distance that matches the grinding amount to perform fine grinding.

[0337] In a possible implementation, the second grinding feed assembly 317 mainly includes a second grinding lateral feed assembly 3171 and a second grinding vertical feed assembly 3172, which are respectively used to realize the lateral / vertical linear feeding of the second grinding head assembly.

[0338] In a possible implementation, the second grinding transverse feed assembly 3171 mainly includes a second grinding transverse lifting slide 31711, two second grinding transverse feed slides 31712 slidably arranged on the second grinding transverse lifting slide in the horizontal direction, and a second grinding transverse feed motor 31713 configured on the second grinding transverse feed slide. As in this example, the two second grinding feed lifting slides are provided with a positioning shaft 31714 for facilitating the positioning of the second grinding head assembly. The second grinding vertical feed assembly 3172 mainly includes a second grinding vertical motor 31721 and a second grinding vertical linear guide 31722 arranged on the second grinding column 311.

[0339] In this way, the second grinding vertical feed motor drives the transverse lifting slide of the second grinding transverse feed assembly to move vertically, thereby driving the second grinding head assembly to achieve its vertical movement. The two second grinding transverse feed motors drive the corresponding second grinding transverse feed slides to move horizontally, thereby driving the second grinding head assemblies to move closer to / away from each other in the horizontal direction.

[0340] In a possible implementation, for the sliding connection between the second grinding transverse feed slide and the second grinding transverse lifting slide, an upper guide rail and a lower guide rail are respectively provided on the second grinding transverse lifting slide, and the installation directions of the two are different. Specifically, the upper guide rail is installed vertically, so it can bear the weight and guide, and the lower guide rail is installed laterally, so it can resist the overturning force and guide. The upper and lower guide rails are both installed with false guide rails near the middle and both ends along their length direction, which not only play a limiting role but also save materials.

[0341] In a possible implementation, the nitrogen balance system 318 mainly includes a nitrogen cylinder 3181, a balance cylinder 3182, a plate chain transmission mechanism 3183 and a nitrogen guide wheel seat 3184. Among them, the nitrogen cylinder that provides the high pressure required for balance is supported by a cylinder bracket and placed on the rear side of the second grinding column. The balance cylinder is fixed to the rear side of the second grinding column through a balance cylinder bracket, and the balance cylinder is guided to the front side of the second grinding column through a plate chain transmission mechanism via a nitrogen guide wheel seat, and the chain screw on the front side of the plate chain transmission mechanism is connected to the second grinding feed lifting slide. In this way, the nitrogen balance system uses the high pressure in the nitrogen cylinder to balance the weight of the second grinding head assembly with the pressure of the balance cylinder, thereby ensuring good dynamic performance during the operation of the second grinding device. Compared with the aforementioned first grinding device configured at the grinding station, since the second grinding device has a larger deadweight, a nitrogen balance system with a stronger balancing ability than the balance cylinder assembly is adopted.

[0342] It should be noted that the specific forms of the various driving components and transmission components mentioned in the above embodiments and the specific detailed structural forms of the components are only exemplary descriptions, and those skilled in the art can flexibly adjust them according to actual needs. For example, it may include but is not limited to: the rodless cylinder can be changed to a rod cylinder, electric cylinder, hydraulic cylinder, linear module, etc.; the double-output shaft drive motor can be changed to two synchronous motors, etc.; a part or all of the drive transmission combination composed of the motor and the gear rack pair / gear pair / screw nut mechanism, etc. can be adjusted.

[0343] It can be seen that in the integrated grinding and polishing machine of the present invention, through the cooperation of the first station, the second station and the third station, the squaring operation of the silicon rod (the edges of the silicon rod can also be cut) and the grinding operation can be realized in the same device. Since the silicon rod does not need to be re-clamped when transported between the stations in the integrated grinding and polishing machine, the processing accuracy of the silicon rod is improved. Since the stations in the integrated grinding and polishing machine include multiple functions, it is expected that the production efficiency of the silicon rod can be improved through the cooperation between the stations.

[0344] In particular, in the integrated opening and grinding machine of the present invention, through the setting of the second workstation, it is possible to share a part of the squaring operation in the first workstation and a part of the grinding operation in the third workstation, and the two operations can be integrated and completed at the same workstation, thereby improving the collaboration between the various workstations in the integrated opening and grinding machine.

[0345] In addition, in the integrated cutting and grinding machine of the present invention, by configuring the cutting device with an integrally movable edge skin support assembly, the edge skin support assembly can be moved forward as a whole to support the edge skin of the cutting and grinding station, and can be moved backward to avoid the operation of the first grinding device and the edge skin removing device of the cutting and grinding station, etc. Therefore, under the premise of ensuring that the functions of the cutting and grinding station of the integrated cutting and grinding machine can be reliably completed, the overall size of the integrated cutting and grinding machine is made more compact. Specifically, the workbench can have a smaller diameter, thereby reducing the floor space of the entire machine, and correspondingly reducing the production cost and transportation cost.

[0346] In addition, although the present embodiment uses an example of a grinding station and a grinding station arranged roughly in parallel to illustrate the grinding machine, it is obvious that those skilled in the art can adjust the number of stations, the specific structure / function of the stations, and the relative position relationship between the stations according to actual needs. For example, the positions of the grinding station and the grinding station are swapped, the grinding station / grinding station / loading and unloading devices are evenly distributed along the axial direction, and a new station that only includes square cutting operations is added.

[0347] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
