Description

Technical Field

[0001] This utility model relates to the technical field of crystal rod processing equipment, specifically a cutting wire wheel used in crystal rod wafer taking out of a cutting machine. Background Technology

[0002] In the current era of rapid development in the photovoltaic industry, the efficiency and stability of production equipment directly affect a company's market competitiveness and product supply capabilities. Among them, the cutting machine, as a key piece of equipment in the photovoltaic crystal rod processing process, undertakes the important task of accurately cutting long crystal rods into specific length specifications. Its operating efficiency and processing quality play a decisive role in the overall efficiency of the production line.

[0003] Currently, the cutting machines commonly used in the photovoltaic industry rely heavily on quality inspection in their production processes. During ingot processing, to ensure product quality meets standards, sample collection and testing are necessary to obtain samples for various performance analyses. In existing production processes, automated feeding stations precisely deliver the ingots into the machine, which then initiates the processing program, using a single-wire wheel to cut the ingots and complete the cutting process. However, this single-wire wheel design has a limited function, only capable of cutting ingots and unable to accommodate the need for sample collection.

[0004] When crystal ingot wafer testing is required during production, the single-wire roller cannot directly cut sample wafers that meet the testing requirements. Currently, manual intervention is necessary. Operators must manually reposition the equipment and adjust cutting parameters to cut the crystal ingots into test wafers only 2 millimeters thick. This manual process is cumbersome and time-consuming, severely impacting the cutting machine's production efficiency and preventing continuous, stable operation. It fails to meet the stringent efficiency requirements of large-scale production. Furthermore, manual operation is inherently uncertain; positioning accuracy and cutting quality are heavily influenced by the operator's skill level and experience, easily leading to cutting deviations that affect the accuracy of the test wafers and consequently interfere with product quality assessment.

[0005] Furthermore, manual operation of cutting equipment poses certain safety risks. During equipment operation, workers need to be in close contact with high-speed rotating cutting components, and even a slight mistake could lead to an accident, threatening the personal safety of the operators. At the same time, manual operation also results in a significant waste of human resources. In repetitive positioning and cutting operations, human resources are not utilized efficiently, increasing the company's production costs.

[0006] Therefore, in order to address the above problems, the applicant needs to design a cutting wheel for use in the crystal rod taking process of the cutting machine. Utility Model Content

[0007] The purpose of this invention is to provide a cutting wire wheel for crystal rod taking out of a cutting machine, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cutting wire wheel for crystal rod wafer taking in a cutting machine, comprising a wire wheel with two sliding grooves, each of which abuts against a cutting wire, and the two cutting wires being used to cut crystal rods or test wafers respectively. A connecting rod is fixedly mounted on the wire wheel and is rotatably connected to an external cutting machine. An adjustment mechanism is provided on the outer side of the two cutting wires and is used to adjust the tension of the cutting wires. The adjustment mechanism includes a tensioning wheel that abuts against the cutting wires, and a fixing rod is provided on the tensioning wheel. A control component is provided at the end of the fixing rod away from the tensioning wheel and is used to drive the tensioning wheel to move linearly.

[0009] Furthermore, the control component includes a movable block connected to a fixed rod, a lead screw is rotatably mounted inside the movable block, and a servo motor is mounted at one end of the lead screw. A fixed frame is mounted on the servo motor and is fixedly connected to the cutting machine, and the fixed frame is slidably connected to the movable block.

[0010] Through the above structural design, the servo motor drives the lead screw to precisely control the displacement of the moving block, realizing the automatic and precise adjustment of the cutting line tension, which significantly improves the equipment response speed and cutting stability.

[0011] Furthermore, a fixed seat is rotatably provided at the end of the lead screw near the servo motor, and the fixed seat is fixedly connected to the fixed frame.

[0012] Through the above structural design, the fixed seat provides stable support for the lead screw, effectively suppressing vibration during high-speed operation and ensuring the smoothness and positional accuracy of the cutting process.

[0013] Furthermore, a stabilizing seat is rotatably provided at the end of the lead screw away from the servo motor, and the stabilizing seat is fixedly connected to the fixing frame.

[0014] Through the above structural design, the stabilizing seat and the fixed seat work together to enhance the support rigidity at both ends of the lead screw, prevent deformation caused by the cantilever structure, and ensure the reliability of long-term operation.

[0015] Furthermore, a sliding rod is fixedly installed on the stabilizing base, and the end of the sliding rod away from the stabilizing base slides through the moving block and is fixedly connected to the fixed base.

[0016] Through the above structural design, the slide bar and the moving block form an auxiliary guiding structure, eliminating the risk of deflection of the moving block during high-speed linear movement and ensuring that the tensioning wheel always acts perpendicularly to the cutting line.

[0017] Furthermore, both of the aforementioned grooves are configured as V-shaped.

[0018] Through the above structural design, the V-shaped groove design increases the contact area and adhesion between the cutting wire and the wire wheel, effectively preventing the wire from coming off or slipping due to inertia during the cutting process.

[0019] Furthermore, the surface of the cutting line is coated with a wear-resistant coating, and the wear-resistant coating is a high-chromium cast iron coating.

[0020] Through the above structural design, the high-chromium cast iron wear-resistant coating significantly improves the surface hardness and wear resistance of the cutting wire, extends its service life, and reduces frequent downtime maintenance caused by wire wear.

[0021] Furthermore, multiple weight-reduction holes are provided on the side wall of the reel.

[0022] Through the above structural design, the weight reduction hole reduces the rotational inertia while ensuring the structural strength of the reel, which is conducive to the rapid start-up and shutdown of the equipment and the switching of speed, thereby improving energy efficiency and dynamic response performance.

[0023] Compared with the prior art, the beneficial effects of this utility model are: This cutting wire wheel, used in the crystal ingot picking process of a cutting machine, integrates dual cutting wires and a tension adjustment mechanism, enabling seamless switching between conventional crystal ingot cutting and ultra-thin test piece cutting. It eliminates the cumbersome, inefficient, and potentially unsafe manual intervention required in traditional processes. Utilizing a servo motor-driven precision lead screw slide mechanism, it ensures rapid, precise, and stable stepless adjustment of the cutting wire tension according to different cutting modes. This improves equipment production efficiency, ensures continuous and stable operation to meet large-scale production demands, and significantly enhances the cutting accuracy and quality consistency of 2mm ultra-thin test pieces, providing reliable samples for downstream product quality assessment. Furthermore, through detailed optimizations such as V-grooves, wear-resistant coatings, and weight-reducing holes, it enhances operational reliability, extends equipment lifespan, reduces maintenance costs, and improves dynamic response performance, ultimately achieving the comprehensive goals of improved safety, reduced human resources, and lower overall production costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, this utility model discloses a cutting wire wheel for crystal rod wafer taking in a cutting machine, including a wire wheel 1, and two sliding grooves 10 are provided on the wire wheel 1. Each of the two sliding grooves 10 abuts against a cutting wire 11, and the two cutting wires 11 are used to cut crystal rods or test wafers respectively. A connecting rod 12 is fixedly provided on the wire wheel 1, and the connecting rod 12 is rotatably connected to an external cutting machine. An adjustment mechanism 2 is provided on the outer side of the two cutting wires 11, and the adjustment mechanism 2 is used to adjust the tension of the cutting wires 11. The adjustment mechanism 2 includes a tensioning wheel 20 that abuts against the cutting wires 11, and a fixing rod 21 is provided on the tensioning wheel 20. A control component is provided at the end of the fixing rod 21 away from the tensioning wheel 20, and the control component is used to drive the tensioning wheel 20 to move linearly.

[0028] The control component includes a movable block 22 connected to a fixed rod 21. A lead screw 23 is rotatably mounted inside the movable block 22, and a servo motor 24 is mounted at one end of the lead screw 23. A fixed frame 26, which is fixedly connected to the cutting machine, is mounted on the servo motor 24. The fixed frame 26 is slidably connected to the movable block 22. Through the precise control method of the servo motor 24 driving the lead screw 23, the position of the movable block 22 can be adjusted accurately and automatically, thereby achieving rapid and stable control of the tension of the cutting line 11. This improves the response speed and adaptability of the equipment to different cutting tasks and ensures the stability and consistency of the cutting process.

[0029] The end of the lead screw 23 near the servo motor 24 is rotatably provided with a fixed seat 25, and the fixed seat 25 is fixedly connected to the fixed frame 26. By setting the fixed seat 25, a solid and reliable rotational support is provided for one end of the lead screw 23, which suppresses the radial runout and vibration that may be generated when the lead screw 23 is running at high speed, greatly enhances the rigidity of the transmission system, and thus ensures the stability of the position of the tension wheel 20 and the cutting line 11 connected to it.

[0030] The end of the lead screw 23 furthest from the servo motor 24 is rotatably equipped with a stabilizing seat 27, which is fixedly connected to the fixed frame 26. The stabilizing seat 27 and the fixed seat 25 at the near end together form a two-point support structure for the lead screw 23, optimizing the force state of the lead screw 23 to pure torsion, improving the rigidity and load-bearing capacity of the entire adjustment mechanism 2, and ensuring the durability and reliability of the equipment under long-term high-load operation.

[0031] A sliding rod 28 is fixedly installed on the stabilizing base 27, and the end of the sliding rod 28 away from the stabilizing base 27 slides through the moving block 22 and is fixedly connected to the fixed base 25. The auxiliary sliding pair formed by the sliding rod 28 and the moving block 22 forms an effective parallel guiding constraint with the main transmission mechanism of the lead screw 23, which prevents the moving block 22 from rotating or deflecting in the circumferential direction during movement, and forces it to only make precise linear movements. This ensures that the force direction of the tensioning wheel 20 is always perpendicular to the cutting line 11, making the application of tension force more direct and effective.

[0032] Both grooves 10 are V-shaped. Designing the grooves 10 as V-shaped can increase the contact area and friction between the cutting wire 11 and the groove wall of the wheel 1, thereby providing stronger adhesion when the wheel 1 rotates at high speed. This effectively prevents the cutting wire 11 from slipping, falling out of the groove, or even breaking due to centrifugal force or cutting resistance, and greatly enhances the reliability and safety of the equipment operation.

[0033] The surface of the cutting wire 11 is coated with a wear-resistant coating, which is a high-chromium cast iron coating. Coating the surface of the cutting wire 11 with a high-chromium cast iron wear-resistant coating improves the surface hardness, wear resistance and corrosion resistance of the wire, thereby extending its service life under high-hardness abrasive wear conditions such as high-speed cutting of silicon.

[0034] Multiple weight-reduction holes 13 are provided on the side wall of the spool 1. The weight-reduction holes 13 on the side wall of the spool 1 can effectively reduce the rotational inertia of the spool 1, so that the drive motor has a smaller load and a faster response when starting, accelerating, decelerating and stopping. This not only reduces energy consumption, but also facilitates rapid switching of cutting rhythm, and improves the dynamic performance and production efficiency of the whole machine.

[0035] When using the cutting wire wheel applied to the ingot picking of the cutting machine, after the equipment is started, the connecting rod 12 is driven by the external driving force to rotate the wire wheel 1. At this time, according to the production command, the servo motor 24 drives the lead screw 23 to rotate, thereby pushing the moving block 22 and the tensioning wheel 20 fixed thereto to move precisely linearly along the slide bar 28. This movement changes the actual effective length of the cutting wire 11 wound in the V-shaped slide groove 10 and passing through the tensioning wheel 20, thereby steplessly adjusting its tension. When performing conventional cutting, a lower tension is used to balance efficiency and loss, while when cutting 2mm ultra-thin test pieces, a high tension is applied to ensure cutting rigidity and stability and prevent the thin pieces from breaking. The processing does not require manual intervention and can automatically complete function switching, tension setting and high-precision cutting without stopping the machine, ultimately meeting the dual requirements of high-efficiency production and accurate picking.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
