Description

Technical Field

[0001] The utility model relates to the technical field of silicon rod processing, in particular to a multi-layer fixture for silicon rod cutting and a silicon rod cutting production line. Background Art

[0002] Cylindrical silicon ingots must first be squared before they can be processed. This square ingot is then further ground to form the finished product. Before the ingot can be cut, it must be cut along its length, often in two.

[0003] In the prior art, when cutting square rods, vertical cutting machines are mostly used, and vertical feeding is used to achieve the cutting of the square rods. Therefore, during the cutting process, vertical positioning and clamping are also used, that is, the two small end faces of the square rod are clamped, which leads to poor stability of the square rod itself when clamped. In addition, due to the size error of the small end face of each silicon rod, the small end face may be uneven, which will cause the steel wire cut to be not in the center position of the silicon rod, making the size consistency of the two half rods after cutting even worse. When processing silicon rods of different specifications, manual adjustment of the clamp is required, which is very troublesome and inefficient. Since there is a non-parallel error between the two end faces of the silicon rod, that is, the end face is not perpendicular to the center line of the silicon rod, the positioning of one end face of the silicon rod itself will cause it to tilt, and the extreme difference value processed is too large, that is, the processing accuracy is low. Utility Model Content

[0004] (1) Technical issues to be resolved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a multi-layer fixture for silicon rod sectioning, which solves the technical problems of large range difference and low processing precision in the prior art silicon rod sectioning process.

[0006] (2) Technical solution

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0008] In the first aspect, the utility model provides a multi-layer clamp for cutting silicon rods, comprising a base and a main centering clamp and an auxiliary centering clamp supported on the base; the main centering clamp and the auxiliary centering clamp each include two clamping jaws, a clamping area is formed between the corresponding two clamping jaws, and the corresponding two clamping jaws can be synchronously approached or synchronously moved away; the two clamping areas extend along the length direction of the silicon rod and are stacked along the height direction of the silicon rod; the main centering clamp clamps the lower part of the silicon rod, and the auxiliary centering clamp clamps the upper part of the silicon rod, and a silicon rod cutting clearance area is formed between the two clamping areas, and the cutting clearance area and the two clamping areas are connected from top to bottom.

[0009] (3) Beneficial effects

[0010] The beneficial effect of the utility model is that after the silicon rod is loaded, the multi-layer clamp for silicon rod cutting of the utility model can realize the positioning and clamping of the silicon rod because the clamping claws of the main centering clamp and the auxiliary centering clamp can move closer to or farther away from each other, ensuring that after the silicon rod is clamped, the center lines of the two clamping areas are in the same vertical plane. For silicon rods with different cross-sectional dimensions, that is, for processing silicon rods of different specifications, no manual adjustment is required, thereby ensuring the adaptability of the multi-layer clamp to the silicon rod model.

[0011] Since both the upper and lower parts of the silicon rod can be reliably and effectively clamped, the silicon rod can remain stable during the process of being divided into two along its own length axis, avoiding the influence of the silicon rod weight during the cutting process, thereby reducing edge collapse during the cutting process.

[0012] After being cut, the two halves of the silicon rod are clamped independently and do not affect each other, thus ensuring the reliability of the silicon rod operation process.

[0013] Compared with the existing vertical positioning fixture, the positioning fixture in this patent has a high adaptability to the silicon rod and can ensure the stability of the silicon rod during the cutting process, thereby improving the silicon rod cutting effect, and thus helping to ensure the quality of the silicon rods subsequently processed.

[0030] In order to better explain the present invention, and to facilitate understanding, the following Figure 1-Figure 7 , through the specific implementation method, the utility model is described in detail. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is referenced.

[0031] Example 1:

[0032] Reference Figure 1-Figure 7 An embodiment of the present invention provides a multi-layer clamp for cutting silicon rods, comprising a base 1 and a main centering clamp 2 and an auxiliary centering clamp 3 supported on the base 1; the main centering clamp 2 and the auxiliary centering clamp 3 each include two clamping jaws 21, and a clamping area 200 is formed between the corresponding two clamping jaws 21, and the corresponding two clamping jaws 21 can be synchronously approached or synchronously moved away; the two clamping areas 200 both extend along the length direction of the silicon rod 100 and are stacked along the height direction of the silicon rod 100; the main centering clamp 2 clamps the lower part of the silicon rod 100, and the auxiliary centering clamp 3 clamps the upper part of the silicon rod 100, and a cutting clearance area for the silicon rod 100 is formed between the two clamping areas 200, and the cutting clearance area and the two clamping areas 200 are connected from top to bottom.

[0033] In this embodiment, after the silicon rod 100 is loaded, since the jaws 21 of the main centering clamp 2 and the auxiliary centering clamp 3 can move closer to or farther away from each other, the silicon rod 100 can be positioned and clamped, ensuring that after the silicon rod 100 is clamped, the center lines of the two clamping areas 200 are in the same vertical plane. For silicon rods 100 with different cross-sectional dimensions, that is, for processing silicon rods 100 of different specifications, no manual adjustment is required, thereby ensuring the adaptability of the multi-layer clamp to the model of the silicon rod 100.

[0034] In the present invention, the end faces of the silicon rod 100 are not involved in the clamping and positioning process; instead, the side faces of the silicon rod 100 are involved. After squaring and grinding, the side faces of the silicon rod 100 are more flat and parallel than the end faces, resulting in greater cutting accuracy for the silicon rod 100. Furthermore, the side faces of the silicon rod 100 are larger than the end faces, further improving the clamping and positioning accuracy of the silicon rod 100 and preventing damage to the silicon rod 100 during the clamping process, thereby ensuring accurate sectioning of the silicon rod 100.

[0035] In addition, the multi-layer fixture for cutting the silicon rod is combined with the production line including a silicon rod parameter detection device, a transfer robot and a wire cutting device, which can keep the silicon rod 100 in a horizontal state throughout the entire processing process, reducing the overall longitudinal space occupancy of the production line. The posture of the silicon rod will not change significantly during the entire processing process, thereby improving the processing efficiency.

[0036] Since both the upper and lower parts of the silicon rod 100 can be reliably and effectively clamped, the silicon rod 100 can remain stable during the process of being divided into two parts along its own longitudinal axis, avoiding the influence of the weight of the silicon rod 100 during the cutting process, thereby reducing edge chipping during the cutting process.

[0037] Taking the example of a silicon ingot 100 that is cut in half along its length, since both the upper and lower portions of the silicon ingot 100 are securely and stably clamped, when transporting the cut upper half of the silicon ingot 100, only the auxiliary centering clamp 3 needs to be loosened. The lower half of the silicon ingot 100 will not be affected by the movement of the upper half, thereby reducing the risk of damage to the silicon ingot 100 during movement. In other words, after being cut, the two halves of the silicon ingot 100 are independently clamped and do not affect each other, thus ensuring the reliability of the silicon ingot 100 during operation.

[0038] Compared with the existing vertical positioning fixture, the positioning fixture in this patent has a high adaptability to the silicon rod 100, and can ensure the stability of the silicon rod 100 during the cutting process, thereby improving the cutting effect of the silicon rod 100, and thus helping to ensure the quality of the silicon rod 100 subsequently processed.

[0039] Specifically, the dual-layer design of the primary and secondary centering fixtures 2 and 3 allows the fixture to flexibly accommodate silicon ingots 100 of varying cross-sectional dimensions. The synchronized approach and separation of the jaws 21 ensures precise and stable gripping regardless of the specific specifications of the silicon ingot 100, eliminating the need for manual adjustment and significantly improving production efficiency and flexibility.

[0040] During the slicing process, silicon ingots 100, especially large or long ones, are prone to shaking or deformation due to their own weight and the slicing force, resulting in reduced slicing quality. However, the multi-layer fixture, through the combined action of the upper and lower clamping areas 200, effectively disperses the stress points on the silicon ingot 100 during slicing, significantly improving the stability of the silicon ingot 100 during slicing and reducing the occurrence of edge chipping. This has a significant impact on the subsequent processing quality and yield rate of the silicon ingot 100.

[0041] The stable and precise cutting achieved by this fixture provides a good raw material basis for the subsequent processing of silicon rods 100, which helps to improve the product quality and competitiveness of the entire silicon industry chain.

[0042] Example 2:

[0043] Reference Figure 1-Figure 7 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0044] The multi-layer fixture further includes a supporting block 4 connected to the base 1 . The top surface of the supporting block 4 forms a supporting surface for supporting the silicon rod 100 along the length direction of the silicon rod 100 . The cross section of the silicon rod 100 is rectangular.

[0045] In this embodiment, the supporting block 4 is used to support the silicon rod 100 in the length direction of the silicon rod 100, thereby further improving the stability of the silicon rod 100 during the clamping process. The supporting surface also serves as a positioning surface for the silicon rod 100 to ensure that the silicon rod 100 extends in a predetermined direction, ensure the cutting accuracy of the cutting process, and ensure the cutting effect.

[0046] Specifically, the support block 4 directly supports the silicon rod 100 along its length, providing a stable support platform for the silicon rod 100. This helps reduce shaking and deviation of the silicon rod 100 during the clamping and sectioning process. The support surface not only supports the silicon rod 100 but also serves as a positioning surface for the silicon rod 100. It ensures that the silicon rod 100 is placed and clamped in the predetermined orientation and position, thereby improving the accuracy of the sectioning.

[0047] The support block 4, along with the primary centering fixture 2 and the auxiliary centering fixture 3, form a comprehensive, multi-layered clamping system. This design allows the silicon ingot 100 to be more firmly and stably clamped before sectioning, reducing sectioning issues caused by loose clamping.

[0048] The design of the support block 4 simplifies the loading and positioning process of the silicon rod 100. The silicon rod 100 can be quickly clamped by simply placing it on the support surface and adjusting the clamping jaws 21. This design reduces the difficulty of operation and improves work efficiency.

[0049] The supporting block 4 serves as an independent component, so that the multi-layer fixture can adapt to silicon rods 100 of different lengths, widths and heights, further improving the versatility and flexibility of the fixture.

[0050] In summary, the support block 4 significantly improves the stability, accuracy and convenience of the multi-layer fixture during the clamping and cutting process of the silicon rod 100, which is not only conducive to ensuring the cutting effect of the silicon rod 100, but also helps to improve the efficiency and reliability of the entire production process.

[0051] Example 3:

[0052] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0053] The main centering fixture 2 and the auxiliary centering fixture 3 also include a fixture body 22; the fixture body 22 corresponding to the auxiliary centering fixture 3 is located on one side of the end face of the silicon rod 100 to form a loading and unloading clearance area for the silicon rod 100 on one side of the silicon rod 100.

[0054] In this embodiment, the fixture body 22 of the auxiliary centering fixture 3 is arranged on one side of the end face of the silicon rod 100, forming a loading and unloading clearance area for the silicon rod 100. The silicon rod 100 can complete the loading and unloading operations relative to the multi-layer fixture through this loading and unloading clearance area without being hindered by other components, which is conducive to improving the loading and unloading efficiency and convenience of the silicon rod 100.

[0055] Specifically, the clamping jaws 21 of the auxiliary centering fixture 3 are cantilever structures relative to the fixture body 22 to better form a clearance area for loading and unloading.

[0056] Example 4:

[0057] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0058] The multi-layer fixture further includes a sliding assembly 5 , through which one of the main centering fixture 2 and the auxiliary centering fixture 3 is supported on the base 1 so as to be able to slide along the length direction of the silicon rod 100 .

[0059] In this embodiment, the sliding assembly 5 allows the fixture to adjust its position along the length of the silicon ingot 100 as needed. This adaptability allows the fixture to more flexibly handle silicon ingots 100 of varying lengths or cutting requirements without having to replace the fixture or adjust the equipment structure. During the cutting process, the sliding assembly 5 allows the fixture to fine-tune its position along the length of the silicon ingot 100 to ensure that the cutting tool is precisely aligned with the cutting line. This helps reduce cutting deviations, improve cutting accuracy, and increase yield.

[0060] Example 5:

[0061] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0062] The sliding assembly 5 is provided as one, and the auxiliary centering fixture 3 is supported on the sliding assembly 5 .

[0063] In this embodiment, by concentrating the sliding function on the auxiliary centering fixture 3, the position adjustment capability of the fixture during the sectioning process can be more focused and optimized. This helps ensure that the auxiliary centering fixture 3 can move accurately and quickly along the length of the silicon ingot 100 when needed to adapt to different sectioning requirements.

[0064] Although only the auxiliary centering fixture 3 is designed to slide, this design still significantly improves the stability of the entire clamping system and ensures the low cost of the multi-layer fixture. The main centering fixture 2 acts as a fixed support, providing a solid foundation for the lower portion of the silicon ingot 100, while the auxiliary centering fixture 3 is adjusted as needed via the sliding assembly 5. Together, these two elements ensure that the silicon ingot 100 maintains a more stable position during the sectioning process.

[0065] Compared to equipping both fixtures with sliding assemblies 5, this design simplifies the fixture system. It reduces unnecessary components and complexity, lowering manufacturing costs and maintenance. Furthermore, the simplified structure improves system reliability and durability. Because the auxiliary centering fixture 3 is slidable, the operator can more flexibly adjust its position to accommodate varying cutting requirements.

[0066] Example 6:

[0067] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0068] The sliding assembly 5 includes a clamp rail 51, a sliding frame 52 and a sliding drive. The clamp rail 51 is fixedly connected to the base 1, and the sliding frame 52 is fixedly connected to the corresponding centering clamp. The sliding frame 52 and the clamp rail 51 are slidingly connected along the length direction of the silicon rod 100, and the sliding drive is drivingly connected to the sliding frame 52; the sliding frame 52 and the corresponding centering clamp are an integrated structure.

[0069] In this embodiment, the clamp rail 51, as the foundation of the sliding assembly 5, is fixedly connected to the base 1 and provides a stable sliding path for the sliding frame 52. The precise machining and installation of the clamp rail 51 ensures smooth sliding of the sliding frame 52, reduces friction and wear, and improves sliding accuracy and reliability.

[0070] The sliding frame 52 is fixedly connected to the corresponding auxiliary centering fixture 3 and slides along the length of the silicon ingot 100 along the fixture track 51. The sliding frame 52 and the auxiliary centering fixture 3 are integrally structured, which strengthens the connection between them and avoids sliding instability caused by loose connections. The design of the sliding frame 52 also takes into account the smoothness and precision of sliding, ensuring the stability and accuracy of the auxiliary centering fixture 3 during sliding.

[0071] In addition, in order to improve the structural compactness of the sliding assembly 5, the sliding frame 52 can be set as a gantry to partially cover the clamp rail 51 inside the gantry, and can also provide protection for the sliding connection position between the clamp rail 51 and the gantry, thereby ensuring the operating stability of the sliding assembly 5.

[0072] The sliding drive is drivably connected to the sliding frame 52, providing the driving force required for sliding. It can be a motor, a pneumatic cylinder, or another type of drive, depending on specific needs. By controlling the sliding drive, the operator can easily adjust the position of the auxiliary centering fixture 3, achieving precise sectioning positioning. Furthermore, automated control of the sliding drive improves production efficiency and sectioning accuracy.

[0073] Example 7:

[0074] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0075] The main centering clamp 2 and the auxiliary centering clamp 3 also include a synchronous drive assembly 23; the synchronous drive assembly 23 includes a telescopic drive member 231, a gear 232, two racks 233 and two clamping claw rails, the telescopic drive member 231 is drive-connected to the gear 232, and the gear 232 is rotatably connected to the base 1 or the clamp body 22; the two racks 233 are both meshed with both sides of the radial direction of the gear 232, and the two racks 233 are correspondingly connected to the two clamping claws 21, the two clamping claw rails are fixedly connected to the corresponding clamp body 22, and the two clamping claws 21 are slidably connected to the corresponding clamping claw rails.

[0076] In this embodiment, the telescopic driving member 231 is the power source of the synchronous driving assembly 23 and can be configured as a cylinder.

[0077] The telescopic driving member 231 can accurately control the telescopic speed and direction, thereby ensuring the synchronization and stability of the clamping jaws 21 when clamping and releasing the silicon rod 100.

[0078] A rack 233 is drivingly connected to the telescopic drive member 231, transmitting the power of the telescopic drive member 231 to the rack 233. The gear 232 and rack 233 transmission has the characteristics of high transmission efficiency and precise transmission ratio, which can ensure that the two racks 233 can move synchronously and smoothly after receiving the rotational power.

[0079] Two racks 233 are located radially on either side of gear 232 and mesh with it. They convert the rotational motion of gear 232 into linear motion, thereby driving the jaws 21 to slide along the jaw track. The meshing of racks 233 and gear 232 ensures that the two racks 233 can move away from or toward each other synchronously, thereby ensuring synchronization and stability during the movement of the jaws 21.

[0080] At the same time, the linear motion characteristics of the rack 233 enable the clamping jaw 21 to accurately control the clamping force and position.

[0081] The clamping jaw track is fixedly connected to the corresponding clamp body 22, providing a sliding track for the clamping jaw 21, thereby ensuring the stability and accuracy of the clamping jaw 21 during the sliding process.

[0082] In summary, the synchronous drive assembly 23 enables the main centering clamp 2 and the auxiliary centering clamp 3 to move synchronously and accurately when clamping the silicon rod 100, thereby improving the clamping accuracy and stability of the clamp, simplifying the operating process, and improving production efficiency, providing a more efficient and accurate cutting solution for the silicon rod 100 processing industry.

[0083] Example 8:

[0084] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0085] In this embodiment, the gear 232 corresponding to the main centering fixture 2 is rotatably connected to the base 1 or the fixture body 22 along the height direction of the silicon rod 100. In this way, the gear 232 will extend along the length direction of the silicon rod 100, thereby reducing the space occupied by the synchronous drive component 23 along the height direction of the silicon rod 100, making the layout of the synchronous drive component 23 more compatible with the extension direction of the main centering fixture 2, thereby improving the structural compactness of the main centering fixture 2, and thereby improving the structural compactness of the multi-layer fixture.

[0086] Whether the gear 232 is fixed to the base 1 or the clamp body 22, it needs to have sufficient rigidity and stability to support the torque generated by the gear 232 during rotation. This can prevent the gear 232 from deflecting or shaking during rotation, thereby ensuring the accuracy and reliability of the movement of the clamping jaw 21.

[0087] Example 9:

[0088] Reference Figure 1-Figure 7 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0089] A contact layer is provided on the clamping surface of the clamping jaws 21; the contact layer is a polyurethane layer.

[0090] In this embodiment, providing a contact layer can effectively prevent the multi-layer clamp from damaging the silicon rod 100 when clamping the silicon rod 100, thereby ensuring the overall quality of the silicon rod 100; by setting the contact layer to polyurethane, the moderate hardness of polyurethane can be utilized to ensure the overall quality of the silicon rod 100 while ensuring that the multi-layer clamp still has good clamping accuracy.

[0091] Specifically, the polyurethane layer as the contact layer has the following significant advantages:

[0092] Polyurethane material has excellent wear resistance, maintaining the flatness of the clamping surface and the stability of the clamping force over extended periods of use. This is particularly important in processes that require frequent clamping and release of silicon ingots 100, as it reduces the loss of clamping accuracy and surface damage to the silicon ingots 100 caused by wear on the clamping surface.

[0093] The polyurethane material has a certain degree of elasticity, providing appropriate cushioning and adaptability when clamping the silicon rod 100. This elasticity helps it better conform to the shape and size of the silicon rod 100, improving the stability and reliability of the clamping. It also reduces, to a certain extent, the damage to the silicon rod 100 caused by excessive clamping force.

[0094] During processing, the silicon rod 100 may come into contact with various chemicals, such as cutting fluids, cleaning agents, etc. Polyurethane material has good chemical resistance and can resist the erosion and corrosion of these chemicals, maintaining the integrity of the clamping surface and the stability of the clamping performance.

[0095] The softness and elasticity of the polyurethane layer enable it to reduce friction and scratches on the surface of the silicon rod 100 when in contact with the silicon rod 100. This is particularly important for applications where the surface finish and integrity of the silicon rod 100 must be maintained, such as in semiconductor manufacturing and solar panel production.

[0096] In summary, providing a polyurethane layer as a contact layer on the clamping surface of the clamping jaws 21 is a practical and effective design improvement. It not only improves the stability and reliability of the clamping, but also protects the surface of the silicon ingot 100 from damage, providing a more efficient and accurate cutting solution for the silicon ingot 100 processing industry.

[0098] Figure 1-Figure 7 In addition to providing a silicon rod 100 slitting production line, the embodiment of the present invention includes the multi-layer fixture for silicon rod slitting in any of the above embodiments, and also includes a silicon rod parameter detection device, a transfer robot and a line slitting device. The silicon rod parameter detection device is suitable for measuring the length, width and height of the silicon rod 100, the transfer robot is suitable for transferring the silicon rod 100 to the clamping area 200 for clamping, and the line slitting device is suitable for slitting the silicon rod 100 along the length direction of the silicon rod 100. Therefore, the silicon rod 100 slitting production line includes all the beneficial effects of the multi-layer fixture for silicon rod slitting in any of the above embodiments. To avoid repetition, they are not described in detail here.

[0099] At the same time, the production line has multiple functions for processing silicon ingots 100, including a multi-layer fixture for cutting silicon ingots 100, a silicon ingot parameter detection device, a transfer robot, and a wire cutting device. The following is a detailed description of the production line:

[0100] The silicon rod parameter detection device is used to measure key parameters of the silicon rod 100, such as length, width and height, to provide accurate data support for subsequent cutting operations, so that the wire cutting device can accurately determine the cutting position.

[0101] The multi-layer clamp is used to stably clamp the silicon ingot 100, ensuring that the position of the silicon ingot 100 remains unchanged during the sectioning process. It adopts a dual design consisting of a main centering clamp 2 and an auxiliary centering clamp 3. The sliding assembly 5 enables flexible adjustment of the auxiliary centering clamp 3 along the length of the silicon ingot 100. The clamp is also equipped with a synchronous drive assembly 23, ensuring that the two jaws 21 can synchronously and accurately clamp the silicon ingot 100.

[0102] The transfer robot is responsible for transferring the silicon rod 100 from its initial position to the parameter detection device for parameter measurement of the silicon rod 100. It is also used to transport the silicon rod 100 with measured parameters to the holding area, and is also used to move the cut silicon rod 100 from the holding area to the subsequent process, effectively reducing the burden of manual handling and improving the degree of automation of the production line.

[0103] The wire cutting device is a cutting tool in the production line, which cuts along the length direction of the silicon rod 100 and cuts the silicon rod 100 into a desired length and shape.
