Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of single crystal silicon rod processing, and in particular to a rod-taking device for a single crystal silicon rod cutting machine. Background Technology
[0002] In the semiconductor and photovoltaic industries, monocrystalline silicon rods are an important basic material, and every step of their production and processing is crucial. Monocrystalline silicon rod cutting is a key process in monocrystalline silicon rod processing, and the rod-taking device, as an important component of the cutting machine, directly affects the efficiency, accuracy, and product quality of the cutting operation.
[0003] Currently, existing rod-picking devices for monocrystalline silicon rod cutting machines on the market have many shortcomings. For example, when clamping monocrystalline silicon rods, insufficient clamping force can easily lead to slippage, and the clamping stability is insufficient. Secondly, in terms of rod-picking efficiency and accuracy, some traditional rod-picking devices have low positioning accuracy. Their drive mechanisms often use relatively simple structures, which cannot achieve precise control of the rod-picking position, leading to deviations during the rod-picking process. This affects the accuracy of subsequent cutting processes, thereby reducing product quality and production efficiency. Moreover, these devices have slow response speeds, making it difficult to quickly and accurately pick up monocrystalline silicon rods of different specifications and positions, and failing to meet the needs of large-scale, diversified production.

[0029] like Figures 1 to 5 As shown, in this embodiment, the present invention includes a machine base 1, on which a first driving mechanism 2 is provided. The first driving mechanism 2 can drive a bearing rod 3 to move horizontally. The lower end of the bearing rod 3 is connected to a first connecting seat 5. The lower end of the first connecting seat 5 is connected to a second connecting seat 7 via multiple first telescopic rods 6. A second driving mechanism 8 is provided on the first connecting seat 5. The second driving mechanism 8 can drive a suspension 9 to rise and fall. The suspension 9 is connected to the second connecting seat 7. A clamping driving mechanism is provided at the bottom of the second connecting seat 7. The clamping driving mechanism can drive two movable seats 11 to open and close. A second telescopic rod 12 is provided on the inner side of the movable seat 11. A mounting seat 13 is provided on the inner side of the second telescopic rod 12. An arc-shaped clamping plate 15 is provided on the mounting seat 13. An anti-slip pad 16 is provided on the inner side of the arc-shaped clamping plate 15. The movable seats 11 and the mounting seats 13 are both made of high-strength materials to ensure the stability and connection strength of the overall structure.
[0030] When it is necessary to grasp the monocrystalline silicon rod, the first driving mechanism 2 drives the bearing rod 3 to move horizontally and the second driving mechanism 8 drives the suspension 9 to rise and fall, so as to adjust the horizontal and height positions of the arc-shaped clamping plate 15, so that the two arc-shaped clamping plates 15 can grasp the monocrystalline silicon rod and move the monocrystalline silicon rod to the cutting position to prepare for the cutting operation.
[0031] In contrast to the shortcomings of existing technologies, the design of the arc-shaped clamping plate 15 and the anti-slip pads 16 installed on its inner wall in this invention allow it to fit tightly against the curved surface of the object being clamped, effectively increasing the friction force for clamping the monocrystalline silicon rod, thereby providing a stable clamping force, preventing slippage, and improving safety. Secondly, the first telescopic rod 6 and the second telescopic rod 12 allow the device to be adjusted at different heights and positions to accommodate monocrystalline silicon rods of different specifications, enhancing the device's versatility and adaptability. Furthermore, the suspension 9 effectively disperses the stress generated during operation, reducing mechanical wear and extending the device's service life. Therefore, this invention has the advantage of good stability during clamping.
[0032] In some embodiments, the inner side of the arc-shaped clamping plate 15 is provided with a fastening groove 17, and the anti-slip pad 16 is fixedly connected to the fastening groove 17 by a fastening block 18; each arc-shaped clamping plate 15 has two fastening grooves 17 on its inner side, and the fastening block 18 is a convex fastening block. The fastening block 18 is made of wear-resistant material to ensure that it is not easily worn during use. Specifically, the fastening groove 17 and the fastening block 18 further enhance the stability of the clamping, ensuring that the single crystal silicon rod can still be firmly clamped under high-speed operation and vibration environments, avoiding accidents caused by loosening.
[0033] In some embodiments, the machine base 1 has a transmission body 19, in which a mounting cavity 20 is provided. The first drive mechanism 2 is located in the mounting cavity 20. A strip-shaped hole is opened at the center of the bottom of the mounting cavity 20. The bearing rod 3 passes through the strip-shaped hole from top to bottom and can move within the strip-shaped hole. The machine base 1 is made of high-strength steel, possessing good stability and load-bearing capacity. A main board is provided inside the transmission body 19, and the main board is fixed to the top of the machine base 1 with bolts, ensuring a firm connection between the main board and the machine base 1. The transmission body 19 is mounted on the surface of the main board and is manufactured using precision casting. The mounting cavity 20 has a spacious interior, facilitating installation and maintenance. The strip-shaped hole guides and supports the movement of the single-crystal silicon rod. Specifically, the strip-shaped hole facilitates the installation and debugging of the device, reduces operating steps, and lowers labor costs.
[0034] In some embodiments, the first drive mechanism 2 includes a lead screw 21 and a servo motor 22. The servo motor 22 is connected to the lead screw 21, and a nut 23 is connected to the lead screw 21. The nut 23 is connected to the support rod 3. The lead screw 21 is rotatably connected to the transmission body 19 via bearings to ensure smooth rotation. The servo motor 22 is mounted on the outer wall of one side of the transmission body 19, with one end of its drive shaft extending into the interior of the transmission body 19 and connected to one end of the lead screw 21 via a coupling. The servo motor 22 employs a high-precision servo control system, capable of precisely controlling the rotation speed and position of the lead screw 21. Specifically, the nut 23 is threaded onto the lead screw 21. As the lead screw 21 rotates, the nut 23 moves linearly along the lead screw 21, further driving the support rod 3 to move linearly horizontally. Specifically, the connection between the servo motor 22 and the lead screw 21 enables precise control of the bearing rod 3, thereby improving the positioning accuracy of the rod-picking device. The high response speed and precise control capability of the servo motor 22 make the rod-picking process faster and more accurate, significantly improving production efficiency.
[0035] In some embodiments, the second drive mechanism 8 includes a rotary motor 25 connected to a threaded rod 24, which is connected to a screw cylinder 26, which is connected to the suspension 9. Specifically, the arrangement of the rotary motor 25 and its connection to the threaded rod 24 further enhances the flexibility of the device, enabling precise rod picking at different angles and positions, thus meeting diverse production needs.
[0036] In some embodiments, the clamping drive mechanism includes an opening and closing cylinder that can drive the two movable seats 11 to open and close.
[0037] In some embodiments, the suspension 9 is connected to the second connecting seat 7 by a hinge or bolt. Specifically, the bottom of the suspension 9 is connected to the top of the second connecting seat 7 by a connector (such as a hinge or bolt) to ensure that the suspension 9 remains stable during lifting and lowering.
[0038] In some embodiments, the number of the first telescopic rods 6 is four. Specifically, both the first telescopic rods 6 and the second telescopic rods 12 are made of alloy materials with good telescopic properties, enabling them to expand and contract under external force.
[0039] In some embodiments, the anti-slip pad 16 is a rubber pad. Specifically, the anti-slip pad 16 is made of highly elastic rubber material, which can provide good cushioning during clamping and prevent damage to the surface of the clamped object.
[0040] The usage process of this application embodiment is as follows:
[0041] Equipment preparation:
[0042] Check that the connections of all components, including machine base 1, main board, and transmission body 19, are secure. Ensure that the high-strength steel structure of machine base 1 is stable, that the main board is tightly fixed to machine base 1 with bolts, and that the transmission body 19 is securely mounted on the surface of the main board. Confirm that the wiring of electrical equipment such as servo motor 22 and rotary motor 25 is correct, and that the control system is operating normally. Confirm that the high-precision servo control system of servo motor 22 has been set with the appropriate parameters. Check that retractable components such as the second telescopic rod 12 and the first telescopic rod 6 can extend and retract normally, that the anti-slip pads 16 on the inner wall of the arc-shaped clamping plate 15 are securely installed, and that the fastening block 18 can be flexibly adjusted and is securely fixed within the fastening groove 17.
[0043] Location and movement:
[0044] When a single-crystal silicon rod needs to be removed, the servo motor 22 is activated by the control system according to the position and height of the single-crystal silicon rod. The servo motor 22 drives the lead screw 21 to rotate. Since the nut 23 is threadedly connected to the lead screw 21, the nut 23 will move linearly on the lead screw 21 as it rotates. The nut 23 drives the bearing rod 3 to move, thereby moving the first connecting seat 5, the second connecting seat 7 and related components to a suitable horizontal position. At the same time, the strip hole can guide and support the movement of the single-crystal silicon rod.
[0045] Height adjustment:
[0046] If the height of the rod-picking device needs to be adjusted, the rotary motor 25 is started. The rotary motor 25 drives the threaded rod 24 to rotate. Since the threaded rod 24 is equipped with a suspension 9 on its outer side through the spiral cylinder 26, and the inner wall of the spiral cylinder 26 has an internal thread that matches the threaded rod 24, the rotation of the threaded rod 24 will cause it to move up and down inside the spiral cylinder 26. The suspension 9 drives the second connecting seat 7 to rise or fall. The first telescopic rod 6 can assist the second connecting seat 7 in smoothly adjusting its height, so that the arc-shaped clamp 15 reaches a suitable height position to adapt to the height of the monocrystalline silicon rod.
[0047] Clamping a single-crystal silicon rod:
[0048] Once the second connecting seat 7 reaches the appropriate position, the second telescopic rod 12 is activated. The second telescopic rod 12 extends, pushing the arc-shaped clamping plate 15 towards the monocrystalline silicon rod until the arc-shaped clamping plate 15 adheres to the surface of the monocrystalline silicon rod. Because the inner wall of the arc-shaped clamping plate 15 is equipped with anti-slip pads 16, the anti-slip pads 16 increase the friction between the plate and the monocrystalline silicon rod. Simultaneously, the cooperation between the fastening block 18 and the fastening groove 17 ensures the stability of the anti-slip pads 16, allowing the arc-shaped clamping plate 15 to firmly hold the monocrystalline silicon rod and prevent slippage.
[0049] Rod removal operation:
[0050] After confirming that the monocrystalline silicon rod has been firmly clamped, the servo motor 22 is started again, causing the lead screw 21 to rotate in the opposite direction. The nut 23 drives the bearing rod 3, the first connecting seat 5, the second connecting seat 7 and the clamped monocrystalline silicon rod to move upward, removing the monocrystalline silicon rod from its original position.
[0051] Move to the cutoff position:
[0052] Through the coordinated control of servo motor 22 and rotary motor 25, the rod-picking device is moved above the cutting position of the monocrystalline silicon rod cutting machine. Based on the cutting requirements, the height and horizontal position of the rod-picking device are readjusted to position the monocrystalline silicon rod at the appropriate cutting position.
[0053] Release single-crystal silicon rods:
[0054] The second telescopic rod 12 is activated to retract, causing the arc-shaped clamping plate 15 to move away from the monocrystalline silicon rod, thus releasing the clamp on the monocrystalline silicon rod. The monocrystalline silicon rod is now in the cutting position, ready for the cutting operation. The rod-retrieving device can either perform the next rod-retrieving task as needed or return to its initial position to stand by.
[0055] Equipment maintenance:
[0056] During or after use of the device, regularly inspect the wear of each component, such as the anti-slip pad 16, fastening block 18, second telescopic rod 12, and first telescopic rod 6. Replace or adjust worn parts promptly to ensure the normal operation of the device and the accuracy, stability, and safety of rod removal. Simultaneously, conduct routine inspections and maintenance of electrical equipment to ensure the normal operation of the control system.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
