Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment for hard and brittle material workpieces such as silicon rods, and specifically provides a cutting component and a cutting and grinding integrated machine comprising the cutting component. Background Art

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

[0003] Among them, along with the development of related industries (such as the photovoltaic industry), in addition to the aforementioned square rods, there is also a demand for silicon wafer products corresponding to half rods. For example, a half rod is usually obtained by performing a mid-section operation along its length direction on the basis of a square rod or a finished square rod. When performing a mid-section operation on a silicon rod, in order to ensure the quality of the mid-section, it is necessary to ensure the accuracy of the mid-section position of the square rod and the smoothness of the feeding of the cutting line during the mid-section process. At present, there is still room for improvement in the related structures. In addition, when performing a mid-section operation on a silicon rod, the cutting line behind the cutting wheel often cuts the silicon rod for the second time during the feeding process, which causes cutting errors and increases the loss of silicon rods. Utility Model Content

[0004] In order to solve the above technical problems at least to a certain extent, the present utility model is proposed. Specifically, how to optimize the equipment that can obtain half-rods is the technical problem to be solved by the present utility model. For example, the optimization aspects may include but are not limited to reducing the loss of silicon rods while improving the accuracy of the mid-section position and improving the feeding smoothness of the cutting line during the mid-section process.

[0005] In a first aspect, the utility model provides a cutting assembly, which comprises: a carrier assembly; and a cutting head assembly; wherein the carrier assembly comprises a carrier base, the carrier base comprises a first carrier base and a second carrier base, and a gap is provided between the first carrier base and the second carrier base; wherein a carrier adjustment assembly is provided on the carrier base, and the workpiece to be processed is fixed to the carrier base by means of the carrier adjustment assembly; wherein the cutting head assembly comprises a wheel assembly, and the wheel assembly comprises: a cutting wheel unit, which comprises at least two cutting wheel assemblies; a supporting wheel unit; the cutting wheel unit and the supporting wheel unit constitute a winding structure, and the winding structure forms a cutting section between adjacent cutting wheel assemblies.

[0006] Through the cooperation of the loading platform assembly and the cutting head assembly, it is possible to achieve the cutting operation of the silicon rod waiting for processing. Through the setting of the loading platform adjustment assembly, it is possible to ensure the posture reliability of the workpiece to be processed during the cutting, thereby improving the accuracy of the cutting position and ensuring the reliability of the cutting operation. It is understandable that those skilled in the art can determine the structural form, limit mode / direction, etc. of the loading platform adjustment assembly according to actual needs.

[0007] Furthermore, since the cutting section is the part for cutting the workpiece to be processed, the part of the winding structure located behind the cutting section will not perform secondary cutting on the workpiece to be processed, thereby avoiding the cutting error caused thereby.

[0008] Taking the case where a circular cutting line is wound on the winding structure as an example, since the cutting line located in the cutting section cuts the workpiece to be processed and the part located behind the cutting section does not perform a secondary cutting on the workpiece to be processed, the cutting error caused by this is avoided. Specifically, the conventional circular cutting line configured in the cutting machine head assembly includes two vertical cutting lines close to the silicon rod and far away from the silicon rod. Since the diameter of the cutting wheel is limited, the distance between the two cutting lines is small. In this way, after the section of the cutting line close to the silicon rod cuts the silicon rod, the section of the cutting line far away from the silicon rod will perform a secondary cutting on the silicon rod. In this way, since it is difficult to ensure that the two sections of the cutting line are absolutely coplanar in engineering, this will cause cutting errors and increase the loss of the silicon rod. In the utility model, the distance between the two sections of the cutting line along the feeding direction is enlarged by the wheel assembly, so that during the feeding process, only the cutting line in the cutting section located in the front participates in the cutting, and the other section of the cutting line located behind the winding structure will not produce a secondary cutting on the silicon rod, thereby avoiding the generation of cutting errors and ensuring the cutting quality.

[0009] In addition, in conventional annular cutting lines, both sections of the cutting line supported between the two cutting wheels will participate in cutting, while the utility model constructs a winding structure so that the annular cutting line only participates in cutting when it is located in the cutting section. This is equivalent to reducing the wear of the annular cutting line, and thus to a certain extent prolonging the service life of the annular cutting line and reducing the frequency of line replacement of the annular cutting line.

[0010] It should be noted that the background technology is mainly combined with the logic of actual products to lead to the present invention. In fact, when the cutting assembly of the present invention is applied to a cutting and grinding machine, technical effects such as compact structure, high cutting accuracy, and low frequency of changing the ring cutting line can be obtained. Obviously, similar effects can be obtained when the cutting assembly of the present invention is applied to other scenarios such as a cutting and grinding machine or a separate wire cutting machine.

[0011] For the above-mentioned cutting assembly, in a possible embodiment, a loading platform base is provided on the first loading platform base or the second loading platform base, and the side of the workpiece to be processed can be abutted against the loading platform base, and the loading platform adjustment assembly includes: a first loading platform adjustment assembly, which can abut against the side of the workpiece to be processed away from the loading platform base; and / or a second loading platform adjustment assembly, which can abut against the top of the workpiece to be processed.

[0012] With such a configuration, it is possible to ensure the reliability of the position of the workpiece.

[0013] For the above-mentioned cutting component, in a possible embodiment, the carrier platform datum is provided with a fixing component on the side close to the first carrier platform adjustment component, and the workpiece to be processed can be fixed to the carrier platform datum with the help of the fixing component; and / or the carrier platform datum is provided with a carrier platform datum buffer structure on the side close to the first carrier platform adjustment component; and / or the carrier platform datum is configured with an adjustment mechanism, and the carrier platform datum can be approached / moved away from the gap along the width direction of the workpiece to be processed with the help of the adjustment mechanism.

[0014] By setting the fixing component, the workpiece to be processed can be reliably fixed on the base of the loading platform through the combination of the loading platform adjustment component and the fixing component. If the fixing component includes a suction cup, obviously, the number of suction cups and their distribution form can be flexibly determined according to actual needs.

[0015] Furthermore, by providing a buffer structure for the carrier base, it is possible to ensure the integrity of the workpiece when it abuts against the carrier base.

[0016] Furthermore, by setting the adjustment mechanism, it is possible to seek compatibility with workpieces of different specifications. For example, the adjustment mechanism can be any reasonable structure that can achieve telescopic movement. If the adjustment mechanism includes an adjustment screw, the position of the loading platform base can be adjusted by screwing the adjustment screw in / out of the long hole.

[0017] For the above-mentioned cutting assembly, in a possible implementation manner, at least one of the cutting wheel assemblies includes a cutting wheel driving component; and / or the supporting wheel unit includes at least two supporting wheel assemblies, at least one of the supporting wheel assemblies is a tension wheel assembly.

[0018] Through such a configuration, a possible configuration of the wheel assembly is provided.

[0019] For example, the cutting wheel driving component may be a motor or a rotating module, and the tension wheel assembly generally includes a tension wheel and a tension wheel adjusting mechanism, and the tension wheel adjusting mechanism is mainly used to adjust the position of the tension wheel, so as to ensure the tension level on the annular cutting line supported on the wheel assembly. For example, the tension wheel adjusting mechanism may include a counterweight assembly and a rotating mechanism that can change the axis position of the tension wheel under the action of the counterweight assembly.

[0020] For the above-mentioned cutting assembly, in a possible embodiment, the cutting wheel assembly includes two, the supporting wheel assemblies include two, the two cutting wheel assemblies and the two supporting wheel assemblies are arranged in a winding structure to form a rectangular structure; and / or the cutting section is a section located between the two cutting wheel assemblies and close to the workpiece to be processed.

[0021] Through such a configuration, a possible structural form of the winding structure is provided.

[0022] The rectangular structure here should be understood as a roughly rectangular structure, such as being understood as a rectangular structure formed by the connecting line of the axes of the four wheel assemblies, or being supported as a rectangular structure when the annular cutting line is wound around the four wheel assemblies. The side of the rectangular structure close to the silicon rod corresponds to the cutting section. By controlling the distance between the side and its opposite side, it can be ensured that the opposite side does not generate the distance between the two sides of the silicon rod. The other pair of opposite sides does not participate in the cutting because they are not in contact with the silicon rod. That is, during the cutting operation of the silicon rod, only one side of the rectangle participates in the cutting operation. By setting the tension wheel assembly, it is possible to seek to ensure the tension level of the annular cutting line.

[0023] For the above-mentioned slicing assembly, in a possible implementation, one of the two cutting wheel assemblies includes a cutting wheel drive component, and one of the two supporting wheel assemblies is a tension wheel assembly; and / or the tension wheel assembly and the cutting wheel assembly including the cutting wheel drive component are located on one of the diagonal sides of the rectangular structure; and / or the cutting head assembly is provided with a wheel protection component at a position corresponding to the wheel assembly.

[0024] With such a configuration, it is possible to seek the functional combination of a driving wheel and a tension wheel to ensure the reliability of the slicing operation.

[0025] By having the two wheels on one of the diagonal sides of the rectangular structure be a driving wheel (the cutting wheel configured with a cutting wheel drive component) and a tension wheel (the tension wheel configured with a tension wheel adjustment mechanism), and the two wheels on the other diagonal side of the rectangular structure be freely rotatable auxiliary wheels, the reliability and stability of cutting are ensured.

[0026] The setting of the wheel protection component can effectively prevent, for example, silicon powder during the slicing process from entering the wire grooves of the annular cutting wire, thereby ensuring the reliability of the slicing operation. For example, the wheel protection component can be a housing, a baffle, or other structures with a protection function. In addition, the wheel protection component can be set for one or more of the wheel assemblies, such as setting one wheel protection component for each row of wheel assemblies.

[0027] For the above-mentioned slicing assembly, in a possible implementation, the cutting head assembly includes a cutting head adjustment assembly. The cutting head base can approach / away from the gap along the width direction of the workpiece to be processed by means of the cutting head adjustment assembly. Among them, the cutting head adjustment assembly includes a cutting head adjustment drive component, a cutting head adjustment transmission component, and a cutting head adjustment guiding component. The cutting head adjustment drive component drives the cutting head base to move along the cutting head adjustment guiding component through the cutting head adjustment transmission component.

[0028] With such a configuration, it is possible to seek to ensure the reliability of the slicing operation.

[0029] For the above-mentioned slicing assembly, in a possible implementation, the slicing assembly includes a slicing feed assembly. The cutting head assembly slices the workpiece to be processed in a manner of moving along the gap by means of the slicing feed assembly. Among them, the slicing feed assembly includes a slicing feed drive component, a slicing feed transmission component, and a slicing feed guiding component. The cutting head assembly is connected to the slicing feed assembly through the cutting head adjustment assembly, and the cutting head adjustment assembly moves along the slicing feed guiding component by means of the slicing feed assembly.

[0030] Such a configuration provides a possible structural form of the cutaway assembly.

[0031] Regarding the above-mentioned cutting component, in a possible implementation manner, the cutting component is a center-cutting component capable of performing a center-cutting operation on a workpiece to be processed.

[0032] Through such a construction, a specific cutting form of the cutting component is provided.

[0033] In a second aspect, the utility model provides a cutting and grinding machine, which includes the cutting assembly described in any one of the above items, and further includes: one or more grinding assemblies, which can grind the workpiece to be processed or the workpiece to be processed after being cut by the cutting assembly.

[0034] It can be understood that the cutting and grinding machine includes all the technical effects of the cutting components described in any of the above items, which will not be repeated here.

[0035] Taking multiple grinding assemblies as an example, through such a configuration, it is possible to achieve the cutting and grinding operations for the workpiece to be processed through the cutting and grinding machine. In addition, since the cutting operation is the process of cutting one workpiece into two, the multiple grinding assemblies can be better adapted to the cutting assembly. For example, those skilled in the art can determine the structural form, functional allocation, relative position, etc. of the multiple grinding assemblies according to actual needs.

[0036] For the above-mentioned cutting and grinding machine, in a possible implementation manner, the grinding assembly includes a first grinding assembly and a second grinding assembly, and the first grinding assembly and the second grinding assembly are capable of at least respectively performing grinding operations on two workpieces generated by the sectioning operation of the workpiece to be processed, wherein the first grinding assembly and / or the second grinding assembly include: a plane grinding assembly, which is capable of at least performing grinding operations on the sectioned surface generated by the sectioning operation; and / or a chamfering grinding assembly, which is capable of at least performing grinding operations on two edges corresponding to the sectioned surface generated by the sectioning operation.

[0037] With such a configuration, it is possible to grind two workpieces of the same mid-section operation simultaneously. For example, the first / second grinding assembly can perform all or part of the grinding operation on the two workpieces.

[0038] It is understandable that those skilled in the art can determine the structural form and number of the plane / chamfer grinding assembly, its specific operation method for grinding the workpiece, the relative position between the two (when the grinding assembly includes a plane grinding assembly and a chamfer grinding assembly), etc. according to actual needs.

[0039] For the above-mentioned cutting and grinding machine, in a possible implementation manner, the cutting and grinding machine includes: a loading component, which can deliver the workpiece to be processed to a position corresponding to the cutting component and / or the grinding component; a unloading component, which can move the workpiece to be processed after the cutting operation and / or the grinding operation out of the cutting and grinding machine; wherein, the loading path corresponding to the loading component and the unloading path corresponding to the unloading component are parallel to each other and / or in opposite directions.

[0040] When the loading path and the unloading path are arranged in parallel and in opposite directions, the connection relationship between the cutting operation / grinding operation and the loading operation, as well as the connection relationship between the cutting operation / grinding operation and the unloading operation can be minimized, thereby making the structure of the cutting and grinding machine more compact.

[0041] It is understandable that the loading component can deliver the workpiece to be processed directly to the position corresponding to the cutting component and / or the grinding component, or can deliver it indirectly. (Similarly, the unloading component can directly or indirectly move the workpiece to be processed from the position corresponding to the cutting component and / or the grinding component to the position of the cutting and grinding machine cutting component and / or the grinding component. Exemplarily, taking the loading component as an example, after the loading component delivers the workpiece to be processed to an intermediate position, an intermediate component (such as a robot, etc.) is introduced, and the intermediate component delivers the workpiece to be processed from the intermediate position to the position corresponding to the cutting component and / or the grinding component.

[0042] For the above-mentioned cutting and grinding machine, in a possible implementation manner, the cutting and grinding machine includes a transfer mechanism, and the loading component can deliver the workpiece to be processed to a position corresponding to the cutting component and / or the grinding component through the transfer mechanism; and / or the unloading component can move the workpiece to be processed after the cutting operation and / or the grinding operation out of the cutting and grinding machine through cooperation with the transfer mechanism.

[0043] With such a configuration, it is possible to reliably feed and remove the workpiece into and out of the integrated cutting and grinding machine.

[0044] It is understandable that those skilled in the art can determine the structural form, movement mode and transfer path formed based on the transfer mechanism according to actual needs. For example, the transfer mechanism includes a manipulator capable of multi-dimensional free movement, and the transfer path can be a straight line, a curve, a broken line, etc.

[0045] In a possible embodiment, the grinding assembly includes a table assembly, the loading assembly or the cutting assembly can deliver the workpiece to be processed to the table assembly via the transfer mechanism, and the surface grinding assembly and / or the chamfer grinding assembly grinds the workpiece to be processed on the table assembly.

[0046] With such a configuration, a possible structural form of the grinding assembly is provided.

[0047] It can be understood that those skilled in the art can determine the structural form of the table assembly according to actual needs. For example, the workpiece to be processed can remain stationary or move after being placed on the table assembly. Correspondingly, the surface / chamfer grinding assembly needs to determine the corresponding operation mode based on the structural form of the table assembly.

[0048] In a possible implementation manner, the table assembly includes: a table part; and a table driving component that can drive the table part to move along the length direction of the workpiece to be processed, so that the surface grinding assembly and / or the chamfer grinding assembly perform grinding operations on the workpiece placed on the table part.

[0049] With such a configuration, a possible structural form of the table assembly is provided.

[0050] In a possible implementation manner, the surface grinding assembly includes a rough grinding wheel and a fine grinding wheel, and the rough grinding wheel and the fine grinding wheel are integrally arranged at the same station.

[0051] With such a configuration, it is possible to ensure the structural compactness of the cutting and grinding integrated machine.

[0052] In a possible implementation manner, the surface grinding assembly includes a composite shaft assembly. The composite shaft assembly includes: a first transmission shaft, which is of a cylindrical structure, and the cylindrical structure is connected to one of the rough grinding wheel and the fine grinding wheel; and a second transmission shaft, which is arranged in the cylindrical structure in a telescopic manner, and the second transmission shaft is connected to the other of the rough grinding wheel and the fine grinding wheel.

[0053] With such a configuration, a possible integration method of the rough grinding wheel and the fine grinding wheel is provided.

[0054] In a possible implementation manner, the surface grinding assembly includes a composite shaft transmission assembly, and the second transmission shaft is arranged in the cylindrical structure in a telescopic manner by means of the composite shaft transmission assembly.

[0055] With such a configuration, a possible implementation method of the telescopic movement is provided.

[0056] For the above-mentioned cutting and grinding integrated machine, in a possible implementation manner, the surface grinding assembly includes at least one set, and each set of the surface grinding assembly includes two; and / or the chamfer grinding assembly includes at least two sets, and each set of the chamfer grinding assembly includes two.

[0057] With such a configuration, the grinding unit can simultaneously grind two half rods produced by one cutting operation.

[0058] For example, for the integrated cutting and grinding machine of the present invention, in a preferred embodiment based on the above solution, the integrated cutting and grinding machine can have at least part of the following technical effects:

[0059] 1. The cutting operation in the cutting and grinding machine of the utility model adopts an annular cutting wire, so the mid-cutting accuracy can be guaranteed. On this basis, through multiple wheel assemblies, only a part of the annular cutting wire is used for cutting at the same time, which effectively prevents the silicon rod after cutting from being cut again by the annular cutting wire. At the same time, since only a part of the cutting wire is used for cutting at the same time, the overall wear of the annular cutting wire is indirectly reduced, and the overall service life cycle of the annular cutting wire is increased.

[0060] 2. The cutting and grinding machine of the utility model is compatible with the sectioning and grinding process of various specifications of workpieces to be processed. The equipment has a compact structure and can realize automatic loading and unloading operations, which improves the operating efficiency of the cutting and grinding machine. In addition, the sectioning station and the double grinding station of the cutting and grinding machine adopt a relatively independent processing method, which can perform sectioning and grinding operations at the same time, saving time.

[0061] 3. The cutting station of the cutting and grinding machine of the utility model adopts vertical processing and horizontal adjustment, which can reduce the cutting error caused by the weight of silicon rods of different specifications (size, weight), and the cutting accuracy is high. The chamfer grinding operation and the section surface grinding operation of the double grinding station can be controlled independently, which is almost not affected by the cutting error, and can also reduce the grinding error and have higher grinding accuracy.

Cutting + Grinding

[0135] Taking the workpiece to be processed as a finished square bar, the cutting component adopts a vertical cutting method along the middle position of the upper surface in the length direction (the cut surface is the aforementioned center section, and the cutting device can also be called the center cutting component), and the grinding component grinds the center section and the edges corresponding to the center section as an example to illustrate the integrated cutting and grinding machine of the present utility model. Therefore, in this example, the workpiece to be processed is a finished silicon bar, and theoretically, two finished half bars with approximately the same size and surface accuracy can be obtained.

Cutting Component

[0137] [Loading platform assembly of the cutting assembly] In a possible embodiment, the loading platform assembly 11 mainly includes a loading platform base, a loading platform reference platform 112, a loading platform clamping assembly 113 and a loading platform pressing assembly 114 arranged on the loading platform base, wherein the loading platform base is formed with a loading surface capable of placing finished square rods, and the loading platform reference platform is provided with an adjustment mechanism so that the loading platform reference platform is adjustable on the loading platform base, and the loading platform reference platform is mainly used to adjust the position of the finished square rod, such as ensuring that the position of the center line of the finished square rod can always be adapted to the cutting position of the cutting assembly, so that the cutting assembly can be compatible with finished silicon rods of various sizes through the setting of the loading platform reference platform. The loading platform clamping assembly and the loading platform pressing assembly are mainly used to fix the square rods on the side and top, respectively.

[0138] It is understandable that those skilled in the art can determine the structural form and number of each component, the structural form and corresponding adjustment method of the reference platform adjustment mechanism, the specific clamping / pressing method of the carrier platform clamping / pressing assembly, etc. according to actual needs. For example, the activity principle and corresponding structural form of the carrier platform clamping assembly and the carrier platform pressing assembly can be the same or different.

[0139] In a possible embodiment, the loading platform base includes a large loading platform base 1111 as a first loading platform base and a small loading platform base 1112 as a second loading platform base. By dividing the loading platform base into two bases, the cutting operation of the loop cutting line can be facilitated. Specifically, the loop cutting line passes through the gap between the two bases. In order to ensure cutting accuracy, it is necessary to ensure that the first / second loading surfaces corresponding to the large / small loading platform bases should be in the same plane.

[0140] In a possible embodiment, the adjustment mechanism (not shown) includes a bolt disposed in the elongated hole, and the position of the loading platform reference platform 112 along the width direction of the finished square rod is adjusted by the movement of the bolt in the elongated hole, so as to ensure that the centers of the finished square rods of different specifications are in the same center position, so that the cutting assembly of the utility model can be compatible with square rods of various specifications. Specifically, by moving the loading platform reference platform 112 closer to / away from the finished square rod along the width direction of the finished silicon rod, the center line of the finished silicon rod can be ensured to be consistent with the mid-section position when the side of the finished square rod abuts against the loading platform reference platform. For example, a loading platform reference platform buffer structure 1121 such as a nylon strip is provided on the loading platform reference platform, so as to ensure the integrity of the finished silicon rod when the side of the finished silicon rod abuts against the loading platform reference platform.

[0141] In a possible implementation, in order to effectively prevent the silicon rod from displacing during the mid-section operation, a fixing component can be configured on the reference table 112 of the loading table. For example, in this example, the fixing component includes a plurality of suction cups 1122 installed on the reference table of the loading table. Obviously, the plurality of suction cups is only an exemplary description of the fixing component, and those skilled in the art can choose any other reasonable method according to actual needs, such as a structure similar to the clamping / pressing component of the loading table.

[0142] In a possible implementation, the loading table clamping component 113 includes a plurality of loading table clamping mechanisms capable of clamping the silicon rod in the horizontal direction. For example, the structures and corresponding clamping methods between the plurality of loading table clamping mechanisms can be the same or different. The plurality of loading table clamping mechanisms can be used alone, in groups, or freely combined. The relative positions (distribution positions, distribution densities, etc.) between the plurality of loading table clamping mechanisms can be flexibly selected according to actual needs. In this example, for instance, the structures of the loading table clamping mechanisms are substantially the same (all cylinders) and are distributed along the length direction of the square bar. Each loading table clamping mechanism can individually clamp the square bar, and thus the combination of the plurality of loading table clamping mechanisms can be used to meet the clamping operations for square bars of different lengths.

[0143] In a possible implementation, the loading table pressing component 114 is mainly used to fix the square bar in the thickness direction. For example, in this example, the loading table pressing component is a cylinder. Obviously, other vertically telescopic structures or mechanisms can also be selected according to actual needs as the loading table pressing component in the present invention.

[0144] In addition, the loading table assembly further includes a loading table detection component. For example, the loading table detection component is mainly used to detect the width of the silicon rod so as to determine the center position of the finished square bar, that is, the cutting position for the mid-section operation of the finished square bar by the annular cutting line.

[0145] [Cutting head assembly of the cutting assembly] In a possible embodiment, the cutting head assembly 12 mainly includes a cutting head base 121 and a wheel assembly arranged on the cutting head base, and a circular cutting line is wound on the wheel assembly. In this example, the wheel assembly mainly includes a cutting wheel assembly, a tension wheel assembly and an auxiliary wheel assembly, and the cutting wheel assembly, the tension wheel assembly and the auxiliary wheel assembly construct a winding structure. In this example, the cutting wheel assembly includes a first cutting wheel 1221 as a driving wheel and a second cutting wheel 1222 as a driven wheel, wherein the first cutting wheel 1221 is configured with a cutting wheel motor 12211 (or it can be a motor with a reducer, etc.) that can drive it to rotate and serves as a cutting wheel driving component, and the winding structure forms a cutting section between the first cutting wheel and the second cutting wheel. The tension wheel assembly includes a tension wheel 123 and a counterweight assembly 1231, and under the action of the counterweight assembly, the tension wheel can maintain the tension level on the circular cutting line by rotating. The auxiliary wheel assembly includes an auxiliary wheel 124, and the auxiliary wheel 124 is pivotally arranged on the cutting head base 121. Exemplarily, wheel protection covers 126 are respectively arranged in the upper area of ​​the wheel assembly, such as above the driven wheel and the tension wheel, to play a protective role such as preventing the splashing of silicon powder etc. generated by the center cut.

[0146] As in this example, follow Figure 11 In the middle position, the (first and second) cutting wheels are located at the lower right and upper right, the tension wheel 123 is located at the upper left, and the auxiliary wheel 124 is located at the lower left. The annular cutting wire wound around the first cutting wheel, the second cutting wheel, the auxiliary wheel and the tension wheel is roughly a rectangular structure. Among them, the area between the first cutting wheel and the second cutting wheel (on the right side) is the cutting section, and the annular cutting wire corresponding to the cutting section can perform a mid-section operation on the silicon rod. Usually, the length of the rectangular structure is extended ( Figure 11 The left-right dimension in the middle) can ensure that the annular cutting wire in the area between the auxiliary wheel and the tension wheel (on the left) does not participate in the cutting, thereby avoiding the problem of the silicon rod being cut twice due to the participation of this part of the annular cutting wire in the cutting, and thus ensuring the accuracy of the middle section and reducing the loss of silicon rods caused by the secondary cutting. In addition, since the annular cutting wire in the area between the auxiliary wheel and the tension wheel (on the left) does not participate in the cutting at this moment, there will be no problem of repeated cutting, which is equivalent to extending the service life of the annular cutting wire, and on this basis, the replacement frequency of the annular cutting wire can be reduced.

[0147] Based on the above structure, the working mode of the cutting head assembly is as follows: the cutting wheel motor drives the driving wheel to rotate at high speed, thereby driving the circular cutting line to move at high speed and thus perform a center sectioning operation on the square rod. During this period, the tension wheel can change its position according to the counterweight assembly so that the circular cutting line can maintain a stable tension level. In addition to the counterweight assembly, it can also be a cylinder, a tension wheel motor, etc. The cutting head base 121 moves along the length direction of the square rod under the drive of the cutting feed assembly 13, so that the circular cutting line of the cutting head assembly can perform a center sectioning operation on the square rod along the center line of the square rod.

[0148] In one possible embodiment, the cutting head assembly is configured with a cutting head adjustment assembly 125, such as a cutting head adjustment assembly that can fine-tune the position of the annular cutting line along the width direction of the square rod to ensure the position accuracy of the annular cutting line, that is, to ensure that the finished square rod can be cut into two half rods of the same thickness.

[0149] It is understandable that those skilled in the art can determine the structural form of the cutting head adjustment component and the cutting feed component and the specific way of forming the cutting component according to actual needs. For example, the cutting feed component can be arranged on the loading platform component, the cutting head adjustment component can be arranged on the cutting feed component, and the cutting head base can be arranged on the cutting head adjustment component.

[0150] In a possible implementation, the cutting head adjustment assembly 125 mainly includes a cutting head adjustment drive component, a cutting head adjustment transmission component and a cutting head adjustment guide component. The cutting feed assembly 13 mainly includes a cutting feed drive component, a cutting feed transmission component and a cutting feed guide component. According to the thickness of the detected square rod, the cutting head adjustment assembly can drive the cutting head assembly to move along the width direction of the square rod, thereby fine-tuning the position of the annular cutting line. After the relative position of the square rod and the annular cutting line is determined, the cutting feed assembly drive component of the cutting feed assembly drives the cutting feed assembly transmission component to move and thus makes the cutting head assembly as a whole move along the cutting feed guide component to complete the middle sectioning process of the silicon rod. For example, the cutting feed / cutting head adjustment drive component can be a motor (or a motor with a reducer, etc.), the cutting feed / cutting head adjustment transmission component can be a belt, a chain, a gear rack mechanism, a screw nut mechanism, etc., and the cutting feed / cutting head adjustment guide component can be a linear guide rail, an optical axis, etc. As in this example, the structure of the cutting head adjustment assembly and the cutting feed assembly is a combination of a drive motor, a screw nut mechanism, and a linear guide rail.

[0151] In this example, the cutting wheel assembly 122 and the tension wheel assembly 123 are slidably arranged on the cutting head adjustment assembly 125 along the width direction of the silicon rod, and the cutting head adjustment assembly 125 is slidably connected to the cutting feed assembly 13 along the length direction of the silicon rod. For example, the cutting head adjustment assembly 125 is provided with a connecting frame 1251, and the cutting head adjustment assembly 125 is fixedly connected to the nut of the lead screw nut mechanism of the cutting feed assembly through the connecting frame 1251. In this way, the cutting head assembly is driven to move along the length direction of the square rod by the cutting feed assembly, and the high-speed rotation of the annular cutting line is coordinated to realize the mid-cutting operation of the finished square rod.

[0152] Based on the above structure, the workflow of the half-rod splitting operation is as follows:

[0153] According to the current specifications of the finished square rod, the loading platform reference platform is first adjusted to a suitable position along the width direction of the finished square rod through the adjustment mechanism. After the finished square rod is placed on the loading platform base, according to the length of the finished square rod, a suitable number of loading platform clamping assemblies are selected to clamp the square rod along the width direction. At the same time, the multiple suction cups on the loading platform reference platform form a vacuum to suck the finished square rod along the width direction. The loading platform clamping assembly is also used to press the finished square rod from top to bottom along the thickness direction. The square rod is fixed by the cooperation of three methods. On this basis, the mid-section position is determined based on the detection results of the loading platform detection assembly.

[0154] After the middle section position is determined, the position of the cutting head assembly can be fine-tuned through the cutting head adjustment assembly to ensure that the annular cutting line coincides with the middle section position. On this basis, the cutting feed assembly drives the cutting head assembly to move along the length direction of the finished square bar, thereby completing the middle section operation of the square bar.

[0155] After the mid-section operation is completed, the loading platform clamping assembly and the loading platform pressing assembly release the square rod, release the vacuum environment of the suction cup, and the two half rods obtained by the mid-section wait for subsequent grinding and unloading.

[0156]

Grinding Assembly

[0157] It can be understood that the configuration of a set of grinding assembly on each grinding station is only an exemplary description. Those skilled in the art can determine the structural form, installation position, and implementation manner of grinding operations between a pair of grinding assemblies corresponding to the two grinding stations according to actual requirements. For example, the structures of a pair of grinding assemblies corresponding to the two grinding stations can be the same or different, and can be symmetrically or asymmetrically arranged when constituting the cutting and grinding integrated machine. In addition, a pair of grinding assemblies corresponding to the two grinding stations can share at least a part of them. For example, a pair of grinding assemblies corresponding to the two grinding stations share one or more chamfer grinding assemblies, etc.

[0158]

Table Assembly of Grinding Assembly

[0159] In a possible implementation, the table portion 211 includes a table base body 2111. The table base body has a vertically arranged reference surface and is provided with a table side clamping assembly 2112 (arranged along the width direction of the silicon rod) as the first table clamping assembly and a table end face clamping assembly (opposed along the length direction of the silicon rod and capable of clamping the two end faces of the silicon rod) as the second table clamping assembly. In this way, after the half rod obtained by mid-section cutting is placed on the table base body, first, a plurality of table side clamping mechanisms (constituting the table side clamping assembly) located on one side of the table base body clamp the half rod along its width direction, so that the half rod can closely abut against the table reference surface of the table base body. On this basis, the surface grinding assembly and the chamfering grinding assembly can be used to perform surface grinding / chamfering operations on the half rod. In order to prevent the half rod from moving longitudinally during grinding, two end face clamping mechanisms (constituting the table end face clamping assembly) will clamp the half rod from both ends before grinding. Then, the table driving and transmission mechanism drives the table portion reliably holding the half rod to feed along the length direction of the silicon rod, and thus the surface grinding and chamfering of the half rod can be completed.

[0160] It can be understood that those skilled in the art can determine the structural forms, relative positions and their corresponding table driving and transmission methods of the two table assemblies according to actual needs. Exemplarily, the table base body is generally a slide table structure. The structures and functions of the table assemblies corresponding to the two grinding stations are substantially the same, and they are generally symmetrically distributed when forming a cutting and grinding integrated machine.

[0161] In a possible implementation, the table driving and transmission assembly 212 mainly includes a table driving component, a table transmission component and a table guiding component. The table driving component drives the table portion to move along the table guiding component through the table transmission component, thereby completing the movement of the table portion. The table driving component can be, for example, a motor (which can be matched with a speed reducer according to requirements). The table transmission component can be, for example, a belt transmission mechanism, a chain transmission mechanism, a gear rack mechanism, a lead screw nut mechanism, etc. The table guiding component can be, for example, a linear guide rail, an optical axis and other structures. For another example, the table driving component can also be a power cylinder (such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc.). In this case, since the table driving component can directly realize linear motion by connecting with the table component, the aforementioned table transmission component can be omitted.

[0162] It can be understood that those skilled in the art can determine the structural forms, numbers and specific clamping principles of the side / table end face clamping assemblies according to actual needs.

[0163] In a possible implementation, the clamping assembly 2112 on the side of the tabletop includes a plurality of them distributed along the length direction of the semi-bar. Each clamping assembly on the side of the tabletop includes a pair of clamping mechanisms on the side of the tabletop that are opposed to each other along the length direction of the semi-bar. Through such an arrangement, the tabletop assembly can be made to be compatible with the clamping requirements for semi-bars of different lengths. For example, when the length of the semi-bar is relatively small, only one or several pairs of the clamping mechanisms in the middle need to be in the working state. When the length of the semi-bar is relatively large, multiple pairs of the clamping mechanisms can be made to be in the working state simultaneously to clamp the semi-bar. For example, in this example, the clamping assembly on the side of the tabletop includes three. For example, the clamping mechanism on the side of the tabletop can be a power cylinder (such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc.), a combination of a motor and a mechanism such as a lead screw nut mechanism / a rack and pinion mechanism, etc.

[0164] In a possible implementation, the clamping assembly at the end of the tabletop includes two end claws 2113. The end claws are configured with an end claw driving component and an end claw transmission component. When it is necessary to clamp the semi-bar from the end, the end claw driving component drives the two side end claws to move closer to each other through the end claw transmission component to clamp the semi-bar. For example, in this example, the claw driving component is a motor (or a speed reducer is configured according to requirements), and the claw transmission component is a lead screw nut mechanism. Among them, there are two screw threads with opposite helix directions on the lead screw of the lead screw nut mechanism, so that a set of driving and transmission mechanisms can be used to achieve the clamping movement of making a pair of end claws move towards the center simultaneously. It can be understood that the end claw transmission component can also be a belt, a chain, a rack and pinion, etc. that can achieve reverse movement on both sides at the same time, or a set of claw driving and transmission mechanisms can be configured for each of the two end claws. For example, the claw driving and transmission mechanism can be a combination of a motor and a transmission mechanism, or a structure that can achieve linear movement such as a power cylinder. In addition, the end claws can also be replaced with other clamping structure forms such as a plate-like structure.

[0165] In a possible implementation, a tool dressing and tool setting component 213, a cooling component, etc. are further provided on the table base 2111. For example, the tool dressing and tool setting component 213 mainly includes a tool setter 2131, a tool dressing structure 2132 (such as a tool dressing stone), a driving and transmission component 2133 for protecting the tool setter, and a protective component 2134 for the tool setter (such as a protective cover). For example, the tool dressing and tool setting component is installed on the table base and can thus complete the tool setting and tool dressing process along with the movement of the table component. For example, the tool setter usually includes multiple groups of installations (perpendicular to the grinding surface / chamfering grinding wheel surface of the first / second grinding component) so as to be able to complete the tool setting operation for the grinding surface grinding wheel and the chamfering grinding wheel. The tool dressing stones also include multiple groups to meet the tool dressing needs of the grinding surface grinding wheel and the chamfering grinding wheel. The driving and transmission component for protecting the tool setter is connected to the protective component for the tool setter. During the grinding operation, the driving and transmission component for protecting the tool setter drives the protective component for the tool setter to retract, thus effectively avoiding the influence of the internal environment of the equipment on the tool setter during grinding. During the tool setting operation, the driving and transmission component for protecting the tool setter drives the protective component for the tool setter to open, thus ensuring that the tool setting operation can be carried out normally. For example, the driving and transmission component for protecting the tool setter can be a combination of telescopic transmission mechanisms such as a power cylinder, a motor, and a lead screw nut mechanism / gear rack mechanism, etc. For example, the cooling component mainly includes a cooling pipeline, a nozzle, etc., and provides grinding coolant for the semi-bar during the grinding operation of the semi-bar to reduce the influence of the grinding temperature on the semi-bar.

[0166]

Grinding Component - Surface Grinding Component

[0167] It can be understood that the description of the two surface grinding components and their specific setting methods is only an exemplary one. Those skilled in the art can determine the structural form, number, relative position, etc. of the surface grinding components according to actual needs. For example, the surface grinding head component only includes one, includes two arranged side by side, etc. Taking the surface grinding head component including two as an example, the structures of the two surface grinding head components can be the same or different.

[0168] In a possible implementation, the surface grinding wheel head assembly is generally configured with a surface grinding balancing device, which is mainly used to balance the gravity of the surface grinding wheel head assembly during movement, thereby improving the dynamic stability of the surface grinding wheel head assembly. For example, the surface grinding balancing device can include a cylinder, an electric cylinder, a nitrogen balancing cylinder, etc. Since the types (corresponding principles) of the balancing devices and related detailed structures have been relatively mature in the field of application, they will not be elaborated in this application.

[0169] In a possible implementation, the surface grinding wheel head assembly 222 mainly includes a rough grinding wheel 2221 for rough grinding the silicon rod and a fine grinding wheel 2222 for fine grinding the silicon rod. In the present utility model, the rough grinding wheel and the fine grinding wheel are concentrically arranged at the same station, and the rough grinding wheel can be freely accommodated in the reserved space formed inside the fine grinding wheel. In this way, the grinding assembly can perform rough grinding and fine grinding operations on the silicon rod at the same station, thus ensuring the structural compactness of the surface grinding wheel head assembly. Obviously, the positions of the fine grinding wheel and the rough grinding wheel can also be interchanged.

[0170] In a possible implementation, the surface grinding assembly 22 further includes a composite shaft assembly 224 disposed on the surface grinding wheel head assembly 222. The composite shaft assembly 224 includes a first transmission shaft 2241 (shaft sleeve) in a cylindrical structure and a second transmission shaft 2242 accommodated in the shaft sleeve. Among them, the first transmission shaft is connected to the fine grinding wheel so as to drive the fine grinding wheel to rotate when the shaft sleeve rotates, and the second transmission shaft is connected to the rough grinding wheel so as to drive the rough grinding wheel to rotate when the second transmission shaft rotates.

[0171] In a possible implementation, the surface grinding assembly 22 further includes a compound shaft transmission assembly 225 configured on the second transmission shaft 2242 of the compound shaft assembly 224. The compound shaft transmission assembly is mainly used to drive the second transmission shaft in the compound shaft assembly to move telescopically relative to the first transmission shaft, so that the rough grinding wheel connected to the second transmission shaft extends and thus is in a working state, or retracts so as not to affect the fine grinding wheel in the working state. Exemplarily, the compound shaft transmission assembly includes a cam 2251. For example, a driving component such as a motor is used to rotate the cam to push the second transmission shaft to extend from the end face of the second transmission shaft. In the case where the driving force is removed, for example, the second transmission shaft can retract by the elastic force of an elastic member such as a spring or a disc spring configured on the second transmission shaft. Obviously, the assembly including the cam (which can be called a cam mechanism for example) is only one structural form of the compound shaft transmission assembly. Those skilled in the art can determine the driving and transmission method of the compound shaft transmission assembly, its connection position with the second transmission method, etc. according to actual needs. For example, it can be that the compound shaft transmission assembly includes a gear-rack transmission mechanism, and the power output end of the compound shaft transmission assembly is connected to the side wall position of the second transmission shaft, etc.

[0172] It can be seen that based on the compound shaft assembly 224 and the compound shaft transmission assembly 225, the specific way for the surface grinding head assembly 222 to perform the grinding operation on the semi-bar (the middle section) is as follows: In the case where rough grinding of the semi-bar is required, the second transmission shaft is moved axially by means of the cam mechanism so that the rough grinding wheel extends beyond the fine grinding wheel. Combining with the movement in the vertical direction realized by the surface grinding assembly with the help of the surface grinding feed assembly, the rough grinding wheel can reach the grinding position. Based on this, by rotating the second transmission shaft (for example, the first / second transmission shafts should be configured with a rotation driving component) to drive the rough grinding wheel to rotate, a rough grinding operation on the middle section can be performed once. In the case where fine grinding of the semi-bar is required, the driving force of the cam mechanism is removed, and the second transmission shaft retracts to reserve space under the action of the elastic force, so that the rough grinding wheel is in a position where it does not interfere with the fine grinding wheel. Based on this, combining with the movement of the grinding assembly along the crossbeam slide, the fine grinding wheel can reach the grinding position. Based on this, by rotating the first transmission shaft (for example, the first / second transmission shafts should be configured with a rotation driving component) to drive the fine grinding wheel to rotate, a fine grinding operation on the middle section can be performed once.

[0173] Exemplarily, the first transmission shaft and the second transmission shaft are configured with a rotation driving component and thus the two are configured to rotate synchronously to form the surface grinding assembly. For example, the rotation driving component is a motor, and the motor is drivingly connected to the compound shaft including the first transmission shaft and the second transmission shaft.

[0174] If the first transmission shaft and the second transmission shaft are configured with bearing boxes as rotational support components, the rotational drive component can be built-in (such as being arranged near the middle or end inside the bearing box) or can be external (such as being arranged at the tail end of the composite shaft or on the lateral side along the radial direction).

[0175] In a possible implementation manner, the surface grinding feed assembly 223 mainly includes a surface grinding feed drive component and a surface grinding feed transmission component. For example, the surface grinding feed drive component is a motor, and the surface grinding feed transmission component is a lead screw-nut mechanism. The structure including the surface grinding head component, the composite shaft component, and the composite shaft transmission component is fixedly connected to the nut of the lead screw-nut mechanism. In this way, under the driving action of the motor, the surface grinding head component can slide in the vertical direction. For example, in order to ensure the stability of the movement, the surface grinding feed assembly can also include vertical guiding components such as linear guides. Obviously, those skilled in the art can determine the specific structural form of the surface grinding feed assembly and the corresponding driving and transmission methods according to actual needs. For example, the surface grinding feed transmission component is a rack and pinion mechanism, etc. Obviously, those skilled in the art can determine the specific structural form of the surface grinding feed assembly and the corresponding driving and transmission methods according to actual needs. For example, the surface grinding feed drive component can be in the form of a motor combined with a speed reducer, the surface grinding feed transmission component is a rack and pinion mechanism, belt drive, chain drive, and the vertical guiding component can be an optical axis, etc.

[0176] In addition, the surface grinding assembly further includes a surface grinding detection assembly. The surface grinding detection assembly is mainly used to detect parameters such as the thickness of the semi-bar before grinding. For example, the surface grinding detection assembly is fixed on the surface grinding head component and moves together with the surface grinding head component. The surface grinding detection assembly mainly measures the thickness of the semi-bar before surface grinding of the semi-bar and after rough / fine grinding, so as to calculate the grinding allowance of the surface grinding and the dimensional accuracy of the ground semi-bar, etc.

[0177]

Chamfer Grinding Assembly of Grinding Assembly

[0178] It can be understood that the two sets of chamfer grinding head assemblies and their specific setting methods are only an exemplary description. Those skilled in the art can determine the structural form, number, relative position, etc. of the chamfer grinding assembly according to actual needs. For example, the chamfer grinding head assembly only includes one set, and each set of chamfer grinding head assemblies includes two arranged on both sides of the chamfer grinding column, etc. Taking the chamfer grinding head assembly including two sets as an example, the structures of the two chamfer grinding head assemblies can be the same or different.

[0179] In a possible implementation, the chamfer grinding feed assembly mainly includes a chamfer grinding tilted feed driving component and a chamfer grinding tilted feed transmission component. For example, the chamfer grinding tilted feed driving component is a motor, and the chamfer grinding tilted feed transmission component is a lead screw nut mechanism. For example, the chamfer grinding head assembly is fixedly connected to the nut of the lead screw nut mechanism. In this way, under the driving action of the motor, the chamfer grinding head assembly can slide in the corresponding tilted direction. For example, in order to ensure the stability of the movement, the chamfer grinding feed assembly can also include a chamfer grinding tilted guiding component such as a linear guide arranged in the tilted direction. Obviously, those skilled in the art can determine the specific structural form of the chamfer grinding feed assembly and the corresponding driving and transmission methods according to actual needs. For example, the chamfer grinding tilted feed driving component can be in the form of a motor combined with a reducer, the chamfer grinding tilted feed transmission component is a gear rack mechanism, a belt drive, a chain drive, and the chamfer grinding tilted guiding component can also be an optical axis, etc.

[0180] In addition, the chamfer grinding assembly includes a chamfer grinding detection assembly, which is mainly used to detect parameters such as the width of the semi-bar before grinding, so as to determine the specifications / dimensions of the semi-bar to be ground and thus determine the position of the chamfer to be ground. For example, the chamfer grinding detection assembly can be fixed on the chamfer grinding feed assembly, such as at a position close to the outside of the slide of the chamfer grinding feed assembly.

[0181] Based on the above structure, the working process of grinding the semi-bar is roughly as follows:

[0182] First, the transfer mechanism places the two semi-bars produced by the first mid-sectioning on the table assembly of the double station respectively. The table side clamping assembly on the table assembly clamps the semi-bar in the width direction. The width measuring assembly in the detection assembly measures the width of the semi-bar to determine the specifications / dimensions of the semi-bar and the position of the chamfer.

[0183] After that, the table drive transmission mechanism moves the table part and the semi-bar thereon to the position corresponding to the surface grinding assembly. The table end clamping assembly on the table assembly clamps the semi-bar in the length direction to prepare for surface grinding and chamfer grinding.

[0184] In the case where the two semi-bars move with the corresponding table assemblies to the grinding positions corresponding to the two surface grinding assemblies, the vertical feed assembly drives the aforementioned grinding head assembly and the thickness measuring assembly to move vertically downward, so as to determine the rough grinding allowance of the semi-bar according to the measurement results of the thickness measuring assembly. The thickness measuring assembly can be retracted after the measurement. Then the grinding operation for the mid-section can be started.

[0185] For example, the grinding operation for the mid-section usually includes: First, the driving component (such as a motor) in the cam mechanism drives the cam to rotate, and the cam pushes out the second transmission shaft (inner shaft) in the compound shaft assembly, so that the rough grinding wheel in the grinding head assembly is lower than the fine grinding wheel. After that, by driving the semi-bar placed thereon by the table assembly to reciprocate horizontally, the rough grinding can be completed. After the rough grinding, the table assembly drives the semi-bar to move to the position corresponding to the chamfer grinding assembly. The chamfer driving component drives the chamfer transmission device to move so that the grinding wheel and the axle box move along the guiding device. The tilting feed driving component of the tilting feed assembly drives the chamfer grinding head assembly (such as including a chamfer grinding wheel, an axle box, etc.) to move along the tilting guiding component so that the chamfer grinding wheel moves to the grinding position corresponding to the chamfer grinding assembly. After that, similar to the aforementioned grinding for the mid-section, by driving the semi-bar placed thereon by the table assembly to reciprocate horizontally, the chamfer grinding for the two edges of one semi-bar can be completed.

[0186] After the chamfer grinding is completed, the table assembly drives the half rod back to the grinding position corresponding to the surface grinding assembly, and the fine grinding allowance is calculated based on the measurement structure of the detection assembly. After that, the cam drive component drives the cam to rotate and retract the inner shaft (under the action of elastic force), so that the height of the fine grinding wheel is lower than the rough grinding wheel. At this time, the table assembly can drive the half rod to reciprocate in the horizontal direction to complete the fine grinding.

[0187] After grinding is completed, the table assembly delivers the half rod 72 that meets the accuracy standard to the position corresponding to the blanking assembly (the position close to the right end), and the table end / side clamping assembly releases the half rod and waits for blanking.

[0188] [Transfer mechanism] In a possible implementation, the cutting and grinding machine 100 also includes a transfer mechanism 3, which is mainly used to transfer the finished square rod 71 to be processed to the cutting and grinding machine and perform transfer operations on the workpiece within the working area of ​​the cutting and grinding machine to support the functions of the cutting and grinding machine.

[0189] In a possible implementation, the transfer mechanism 3 mainly includes a gantry 31 as a support part, a clamping assembly 32 capable of clamping a workpiece, and a transfer drive transmission assembly 33 capable of driving the clamping assembly 32 to achieve transfer movement. It is understandable that those skilled in the art can determine the structural form of the support part, the structural form of the clamping assembly 32 and its corresponding clamping method, the structural form / number of components / drive transmission method / transfer dimension of the transfer drive transmission assembly, etc. according to actual needs. Exemplarily, the support part includes a table, and the transfer drive transmission assembly includes an ACV that can walk freely on the table and can carry a clamping assembly, and the ACV is equipped with a mechanism that can drive the silicon rod to achieve multi-dimensional movement.

[0190] In a possible embodiment, the transfer drive transmission assembly 33 includes an X-axis moving assembly 331 (which can drive the manipulator to realize its movement along the X-axis direction (the width direction of the gantry)), a Y-axis moving assembly 332 (which can drive the clamping assembly to realize its movement along the Y-axis direction (the length direction of the gantry)) and a Z-axis lifting assembly 333 (which can drive the clamping assembly to realize its movement along the Z-axis direction (vertical direction)). It can be understood that the drive transmission mode of the X-axis moving assembly 331, the Y-axis moving assembly 332, and the Z-axis lifting assembly 333 can be the same or different, such as the drive transmission mode of the corresponding assembly can be realized by a combination of a motor and a belt / chain / screw nut mechanism / gear rack mechanism, a power cylinder direct drive, and other structural forms. As in this example, the three feed assemblies are all combinations of motors and gear rack mechanisms.

[0191] In a possible implementation, the clamping assembly 32 is used to clamp the silicon rod along its length direction and adjust the clamping angle of the silicon rod to ensure the clamping accuracy. In this example, the clamping assembly 32 includes a first chuck 321 and a second chuck 322 on the clamping base. Among them, the first chuck is configured with a chuck moving drive component, a chuck moving transmission component, a chuck rotating drive component, a chuck rotating transmission component, and a chuck guiding component. For example, the chuck moving drive component is a lead screw nut mechanism (the lead screw includes two thread segments with opposite helix directions). In this way, the chuck moving drive component drives the first chuck and the second chuck to move closer to / away from each other through the chuck moving transmission component, so as to clamp silicon rods of different lengths. The chuck rotating drive component drives the first chuck to rotate through the chuck rotating transmission component, so as to adjust the clamping angle of the silicon rod. The chuck moving / rotating drive component is a motor or a motor combined with a speed reducer, etc. The jaw moving / rotating transmission component can also be a rack and pinion mechanism, etc. The jaw rotating transmission component can be a belt, a chain, a gear pair, etc. The chuck guiding component can be a guide rail, an optical axis, etc.

[0192] In addition, the transfer mechanism 3 further includes a grasping assembly arranged on the gantry. For example, in this example, the grasping assembly includes a jib crane assembly 334. The jib crane assembly 334 is mainly used to transfer the finished silicon rod from the external environment of the equipment to the loading conveyor line of the loading assembly. A grasping end capable of grasping the finished silicon rod is arranged on the suspension arm assembly 334. For example, in this example, the grasping end includes a plurality of suction cups capable of adsorbing the finished silicon rod from its upper surface. Obviously, those skilled in the art can determine the installation position of the grasping assembly, the structural form of the grasping end, and the corresponding grasping principle according to actual needs. For example, another installation carrier can be configured for the grasping assembly. For example, the grasping assembly includes an overhead rail, and the grasping end is an overhead rail robot, etc.

[0193]

Loading and unloading assembly

[0194]

Loading and unloading component - loading component

[0195] It can be understood that those skilled in the art can determine the specific forms of the loading drive component and the loading transmission component according to actual needs. For example, the loading drive component can be a motor or a form of a motor combined with a speed reducer, etc., and the loading transmission component can be a belt drive, a chain drive mechanism, a gear and rack mechanism, etc.; the loading transmission device can be a belt, a chain, etc. In this example, the loading drive component is a motor, the loading transmission component is a gear and rack mechanism, and the loading conveyor line is a belt.

[0196] In a possible implementation, the part of the loading component 4 located inside the equipment of the slicing and grinding integrated machine is provided with a loading protection component 43. The loading protection component is used to prevent being affected by the complex environment inside the equipment during non - loading operations. For example, the loading protection component includes a loading protection box body 431 that can accommodate the silicon rod. The top of the loading protection box body is a flip - up loading protection cover 432. One end of the loading protection box body along the length direction of the finished square rod (such as the downstream end in the loading direction) is a push - pull loading protection side plate 433. Inside the loading protection side plate, there is a first limiting structure 434 such as a nylon strip. When the end of the finished square rod reaches the position corresponding to the first limiting structure, it means that the loading is in place. For example, the loading position corresponding to the first limiting structure can be used as a horizontal reference plane. One side of the loading protection box body along the length direction of the finished square rod is provided with a loading pressing component 435 (such as a cylinder that can expand and contract along the width direction of the square rod). Inside the inner side of the side corresponding to the loading pressing component, there is a second limiting structure 436 such as a nylon strip. For example, the finished square rod can be pressed along the width direction from the side by the loading pressing component until the side of the finished square rod closely adheres to the position corresponding to the second limiting structure. For example, the loading position corresponding to the second limiting structure can be used as a length reference plane.

[0197] Based on the above structure, the process of loading the finished square bar is as follows: The loading drive component drives the finished square bar on the loading conveyor line into the interior of the cutting and grinding integrated machine through the loading transmission component. When the inner end moves to the horizontal reference plane, the loading pressing component presses the silicon bar along the width direction until the finished square bar is tightly attached to the length reference plane, thus aligning the finished square bar. When the clamping component of the transfer mechanism is ready to clamp the loaded material, the loading protective cover body flips open, and the loading protective side plate is pushed outwards (because the clamping component is relatively long), so as to leave enough clamping space for the clamping component. The loading pressing component releases the finished square bar so that the clamping component can perform corresponding transfer operations. The above-mentioned loading pressing component, the pushing and pulling mechanism for realizing the loading protective side plate, and the flipping mechanism for flipping the loading protective cover plate can also be any structure capable of realizing telescopic movement, such as a cylinder, an electric cylinder, a hydraulic cylinder, a combination of a motor and a rack and pinion mechanism, etc. In addition, the loading protective cover plate and the loading protective side plate can also be removed from the loading protective box in other ways, such as swapping their removal methods, both through flipping / pushing and pulling, etc.

[0198]

Unloading Component of the Loading and Unloading Component

[0199] In a possible implementation manner, the unloading conveyor component 51 is located inside the cutting and grinding integrated machine and has a similar structure to the loading component. For example, it includes an unloading base 511, an unloading drive component, an unloading transmission component, an unloading conveyor line 512, and an unloading protective component 513. The unloading protective box of the unloading protective component includes a flip-up unloading protective cover body 5131 and a push-pullable unloading protective side plate and has a horizontal reference plane (at this time, the horizontal reference plane is located on the downstream side of the unloading direction) and a length reference plane. The principle is similar to that of the loading component and will not be elaborated here. For example, a drying component 514 is arranged at a position close to the outside of the unloading conveyor component, which is mainly used to dry / blow away the water and other attachments on the surface of the semi-finished bar, so as to ensure the cleanliness of the finished semi-finished bar. Obviously, the unloading drive component, the unloading transmission component, the unloading conveyor line, the unloading protective component, etc. of the unloading conveyor component can also be different from those of the loading component.

[0200] In a possible implementation, the blanking transfer assembly 52 is installed outside the equipment of the cutting and grinding integrated machine. The blanking transfer assembly includes two blanking transfer stations (denoted as the first blanking transfer station 521 and the second blanking transfer station 522 respectively). The structure of each blanking transfer station (taking the first blanking transfer station 521 as an example) is similar to that of the foregoing feeding assembly and blanking conveying assembly. For example, it also includes a blanking transfer base body, a blanking transfer driving component, a blanking transfer transmission component, a blanking transfer conveyor line, etc. The blanking transfer driving component drives the blanking transfer conveyor line and the half rod thereon to move along the length direction of the half rod through the blanking transfer transmission component.

[0201] In this example, the two blanking transfer stations are arranged along the width direction of the half rod. The blanking transfer assembly 52 further includes a blanking transfer switching mechanism 523. The blanking transfer switching mechanism can drive the half rod of the two blanking transfer stations to move in the width direction of the half rod. For example, the blanking transfer switching mechanism includes a blanking transfer switching driving component and a blanking transfer switching guiding component. The blanking transfer switching driving component can drive the two blanking transfer stations to move along the blanking transfer guiding component, so as to realize the movement of the double stations in the width direction of the half rod. For example, the blanking transfer switching mechanism can be a combination of a motor (or a motor cooperating with a speed reducer) and a belt / chain / gear rack mechanism / screw nut mechanism, etc., or a direct driving part such as a cylinder, an electric cylinder, a hydraulic cylinder, etc. The blanking transfer switching guiding component can be a linear guide rail, an optical axis, etc. In this example, the blanking transfer switching assembly includes a blanking transfer switching slide plate 5231 serving as the blanking transfer switching base body, and a blanking transfer switching linear guide rail 5232 serving as the blanking transfer switching guiding component is arranged on the slide plate. The blanking transfer switching mechanism includes a cylinder (not shown).

[0202] Based on the above structure, the working process of blanking the half rod is roughly as follows:

[0203] Flip and open the blanking protection cover body, and push the blanking protection side plate outwards, so as to leave enough clamping space for the clamping assembly. The blanking pressing assembly loosens the silicon rod, so that the clamping assembly can perform corresponding clamping and transporting operations. Specifically: The clamping assembly places the ground half rod on the blanking conveyor line of the blanking conveying assembly.

[0204] The blanking transfer switching drive component drives one of the two workstations (such as the first blanking transfer workstation) to move to the blanking position corresponding to the blanking conveying component (during the movement of the semi-bar, the drying component dries the semi-bar). Through the cooperation of the blanking transfer drive component and the blanking transfer switching drive component, the first semi-bar is driven to move outside the equipment (it moves in the width direction after moving in place along the length direction). When the semi-bar at the first blanking transfer workstation moves to the blanking position outside the equipment, the blanking transfer switching drive component drives the other of the two workstations (such as the second blanking transfer workstation) to move, so that the second semi-bar moves to the blanking position, and then the blanking operation for the second semi-bar is carried out through the cooperation of the blanking transfer drive component and the blanking transfer switching drive component.

[0205] It can be understood that those skilled in the art can determine the specific form / number of the blanking transfer workstations, the structural form of the blanking transfer switching mechanism, and the specific way of driving the blanking transfer workstations to move according to actual needs, etc. Still taking the blanking transfer workstations including two as an example, the structural forms, transfer methods, transfer directions, transfer destinations, etc. of the two blanking transfer workstations can be the same or different. Exemplarily, one of the blanking transfer workstations is carried on an ACV, so the transfer route and transfer destination, etc. can be flexibly selected according to actual needs.

[0206] In a possible implementation manner, the cutting and grinding integrated machine 100 further includes a base component. The base component serves as the installation base of the cutting and grinding integrated machine and is mainly used to carry the aforementioned functional components. For example, the base component mainly includes a base and support structures such as the floor feet 62 arranged below the base 61, etc. The floor feet can adopt floor feet with adjustable height to ensure that the functional components installed on the base can have good horizontal accuracy, thereby ensuring the use performance of the cutting and grinding integrated machine.

[0207] Based on the above structure, the work process completed by the cutting and grinding integrated machine is as follows:

[0208] The transfer drive transmission components 33 (X-direction moving component 331, Y-direction moving component 332, Z-direction lifting component 333) of the transfer mechanism drive the clamping component to move in three directions, so that the clamping component moves to the position corresponding to the loading component (above the loading position). At this time, the loading protection flip cover of the loading component is opened, and the loading protection side plate is pushed outwards, so that the clamping component can clamp the finished square bar accommodated in the loading protection box without interference. After the clamping component clamps the finished silicon bar, it transfers it to the loading table of the middle splitting component. At this time, the loading component has been released and can perform the loading operation again, for example.

[0209] After placing the finished square bar on the loading table of the middle cutting assembly, the finished square bar is reliably fixed by the loading table pressing assembly, the loading table clamping assembly, and the suction cup, and the middle cutting position of the finished silicon rod is determined by detecting the width of the finished square bar. Based on this, after the cutting head assembly of the middle cutting assembly moves to a position adapted to the middle cutting position, the finished square bar is subjected to a middle cutting operation by moving the circular cutting wire (of the cutting head assembly) along the length direction of the finished square bar. After the middle cutting is completed, two half bars can be obtained.

[0210] The clamping assemblies of the transfer mechanism clamp the two half bars respectively, and through the transfer drive transmission assembly, the half bars are rotated to the posture with the cut surface to be ground facing upward, and the two half bars are respectively transported to two tabletop assemblies corresponding to the two plane grinding assemblies of the cutting and grinding integrated machine.

[0211] After placing the half bar on the tabletop assembly, the two tabletop side clamping assemblies clamp the half bar in the width direction, and the machining allowance of the plane grinding assembly is determined by detecting the thickness of the half bar. Then, the grinding wheel of the plane grinding assembly moves to the grinding position, and the tabletop assembly drives the half bar to move along the length direction of the half bar to complete the plane grinding process. After the grinding is completed, the chamfering assembly drives the chamfering wheel to move to the machining position, and the sliding table assembly continues to drive the half bar to move along the length direction to complete the chamfering grinding operation. When the half bar is being ground, the jaw assembly can transport the second silicon rod to the middle cutting position, so that the grinding of the first set of half bars and the middle cutting of the second silicon rod are carried out simultaneously, thereby saving the overall machine processing beat.

[0212] When the grinding of the two half bars is completed, the sliding table assembly drives the half bar to move to the blanking position, and the clamping and transporting assembly drives the jaws to transport the two half bars to the blanking device in the equipment respectively. The flip device of the blanking device opens the flip, and the pushing and pulling device opens the side door to cooperate with the jaws to complete the blanking operation. The blanking conveyor line transports the half bar out of the equipment, and the drying device dries the silicon rod during the transportation process. The blanking sliding table assembly has a double station and can accommodate two half bars at the same time.

[0213] It can be seen that in the preferred embodiment of the present invention, the middle cutting operation for the finished square bar and the grinding operation for the two half bars generated by the middle cutting can be realized. By adopting the cooperation of the circular cutting wire and the wheel assembly composed of four wheels, the problem that the middle cutting surface of the half bar generated by the middle cutting is secondarily cut by the circular cutting wire can be effectively prevented. At the same time, since only a part of the circular cutting wire serves as the cutting wire at the same moment, the service life cycle of the circular cutting wire is equivalently increased. Through the setting of the loading table assembly, the cutting and grinding integrated machine of the present invention can be compatible with finished square bars of various specifications and sizes. And, since the middle cutting station corresponding to the middle cutting operation and the grinding station corresponding to the grinding operation are two independent processing areas, the middle cutting operation and the grinding operation can be carried out simultaneously for bar stocks of different forms, saving the beat.

[0214] In addition, in the preferred embodiment of the present utility model, the setting of the double grinding stations can perform relatively independent grinding operations on the two half rods produced by center cutting simultaneously, saving the beat. In addition, after the finished square rod is center cut on the loading table assembly, it is transferred to the tabletop assembly through the transfer mechanism. Therefore, the grinding operation is not affected by the center cutting error, and the precision impact between functions is reduced on the premise of ensuring the realization of functional association. On this basis, by independently controlling the multiple surface grinding components and chamfering grinding components in the two sets of grinding components, the grinding error caused by the association between multiple grinding operations can be reduced.

[0215] So far, the technical solution of the present utility model has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, 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 all fall within the protection scope of the present utility model.
