Currently, most silicon wafers are manufactured by cutting crystalline silicon rods into the required wafers using a slicing machine. When the crystalline silicon rods are cut, the diamond wires in the slicing machine need to be driven by a winding device.

[0003] Chinese Patent No. CN 222245478 U discloses a diamond wire winding device for a slicing machine. The device includes: a cabinet with a winding cavity; a diamond wire wheel frame with the diamond wire wheel mounted within the winding cavity, the frame rotatably and detachably fitted with a diamond wire wheel on which diamond wire is wound; a winding wheel rotatably mounted within the cabinet, the diamond wire adapted to be connected to the winding wheel and wound around it as the wheel rotates; and a drive device connected to the winding wheel. The diamond wire winding device for a slicing machine according to this invention has advantages such as saving time and labor, improving winding efficiency, high reliability, and a high degree of automation.

[0004] Existing diamond wire winding devices generate silicon powder during the slicing of photovoltaic silicon, and some of the silicon powder adheres to the diamond wire. Since it is impossible to clean the silicon powder adhering to the diamond wire, the cutting ability of the diamond wire is easily reduced, resulting in poor cleanliness of the diamond wire and affecting the cutting ability. Therefore, a diamond wire winding device for slicing machines is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a diamond wire winding device for a slicing machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is a diamond wire winding device for a slicing machine, including a base, on which two sets of hydraulic cylinders are mounted, hydraulic rods are mounted on the hydraulic cylinders, and mounting seats are mounted on the hydraulic rods. A control panel is mounted on the side wall of the mounting seat. Two sets of stepper motors are installed inside the mounting seat, and drive wheels are mounted on the output shafts of the stepper motors. The drive wheels are rotatably mounted on the side wall of the mounting seat. Two dust collection cylinders are symmetrically mounted on the mounting seat, and the dust collection cylinders are equipped with... The device has a cavity, and a suction hole is provided on the inner wall of the suction cylinder. A suction pipe is installed on the side wall of the suction cylinder, and the other end of the suction pipe is connected to a suction box. A dust collection box is placed inside the suction box, and a filter plate is installed on the side wall of the dust collection box. An exhaust box is installed on the side wall of the suction box, and exhaust slots are provided on the side walls of the exhaust box and the suction box. A first motor is mounted inside the exhaust box via a base, and a rotor is mounted on the output shaft of the first motor. Fan blades are mounted on the rotor, and a fixing base is mounted on the mounting base. The fixed base has a sliding groove, and a first lead screw is installed on the inner wall of the sliding groove. A slider is assembled in the sliding groove, and a through hole is opened in the slider. The slider is slidably connected to the first lead screw. A winding wheel is rotatably installed on the slider, and a threaded hole is opened in the winding wheel. The winding wheel is sleeved on the outside of the first lead screw through the threaded hole. Two fixing screws are installed on the winding wheel. After the diamond wire rotates stably, the hydraulic rod drives the entire mounting base to move vertically downward. The diamond wire between the two driving wheels cuts the photovoltaic silicon fixed on the base, realizing the slicing of photovoltaic silicon. During this process, silicon powder will adhere to the diamond wire between the two driving wheels, and the diamond wire with silicon powder will enter the dust collection cylinder. The silicon powder on the diamond wire and the air are sucked into the dust collection cylinder, realizing the cleaning of the silicon powder adhering to the diamond wire. This structure can clean the surface of the diamond wire, avoid silicon powder adhering to the diamond wire and causing a decrease in the cutting ability of the diamond wire, and is beneficial to improving the cleanliness of the diamond wire and improving the cutting ability of the diamond wire.

[0007] Preferably, the mounting base has a movable groove, and a second lead screw is rotatably mounted on the inner wall of the movable groove. The threads on the second lead screw are symmetrically opposite in direction. A damping wheel is mounted on one end of the second lead screw. Two movable blocks are symmetrically assembled in the movable groove, and tensioning wheels are rotatably mounted on the movable blocks. By rotating the damping wheels, the second lead screw is driven to rotate, and the second lead screw drives the two movable blocks on it to move synchronously in opposite directions. The two movable blocks drive the two tensioning wheels to move synchronously in opposite directions. The two tensioning wheels spread the diamond wire, causing the tensioning wheels to tighten, thus achieving tensioning of the diamond wire and improving the adjustability of the diamond wire tension.

[0008] The advantages of this utility model are:

[0009] 1. This utility model utilizes the stable rotation of the diamond wire to drive the hydraulic rod to move the entire mounting base vertically downwards. The diamond wire between the two drive wheels cuts the photovoltaic silicon fixed on the base, thus slicing the photovoltaic silicon. During this process, silicon powder adheres to the diamond wire between the two drive wheels, and the diamond wire with silicon powder enters the dust collection cylinder. The silicon powder adhering to the diamond wire is sucked into the dust collection cylinder along with the air, thus cleaning the silicon powder adhering to the diamond wire. This structure can clean the surface of the diamond wire, preventing silicon powder from adhering to the diamond wire and reducing its cutting ability, which is beneficial to improving the cleanliness of the diamond wire and improving its cutting ability.

The second lead screw drives the two moving blocks on it to move synchronously in opposite directions. The two moving blocks drive the two tensioning wheels to move synchronously in opposite directions. The two tensioning wheels spread the diamond wire, making the tensioning wheels taut, thus achieving tensioning of the diamond wire and improving the adjustability of the diamond wire tension.

[0018] 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 scope of protection of the present utility model.

[0019] Please see Figure 1-5 As shown, a diamond wire winding device for a slicing machine includes a base 1, on which two sets of hydraulic cylinders are mounted. Hydraulic rods 2 are mounted on the hydraulic cylinders, and mounting seats 3 are mounted on the hydraulic rods 2. A control panel 4 is mounted on the side wall of the mounting seat 3. Two sets of stepper motors are installed inside the mounting seat 3. Drive wheels 5 are mounted on the output shafts of the stepper motors and rotatably mounted on the side wall of the mounting seat 3. Two dust collection cylinders 6 are symmetrically mounted on the mounting seat 3. Each dust collection cylinder 6 has an internal cavity and a dust collection hole 7 on its inner wall. A dust collection pipe 8 is mounted on the side wall of the dust collection cylinder 6, and the other end of the dust collection pipe 8 is connected to… A dust collection box 9 is connected to the mounting base 3. A dust collection container 10 is placed inside the dust collection box 9. A filter plate is installed on the side wall of the dust collection container 10. An exhaust box 11 is installed on the side wall of the dust collection box 9. Exhaust slots 12 are formed on the side walls of the exhaust box 11 and the dust collection box 9. A first motor 13 is mounted inside the exhaust box 11 via a base. A rotor is mounted on the output shaft of the first motor 13. Fan blades 14 are mounted on the rotor. A fixed seat 15 is mounted on the mounting base 3. A sliding groove 16 is formed inside the fixed seat 15. A first lead screw 17 is installed on the inner wall of the sliding groove 16. A slider 18 is assembled inside the sliding groove 16. A through hole is formed inside the slider 18. Block 18 is slidably connected to the first lead screw 17. A winding wheel 19 is rotatably mounted on the block 18. The winding wheel 19 has a threaded hole and is sleeved around the first lead screw 17 through the threaded hole. Two fixing screws 20 are installed on the winding wheel 19. During operation, existing diamond wire winding devices generate silicon powder during the slicing of photovoltaic silicon, and some of the silicon powder adheres to the diamond wire. Because it is impossible to clean the silicon powder adhering to the diamond wire, the cutting ability of the diamond wire is easily reduced, resulting in poor cleanliness of the diamond wire and affecting the cutting ability of the diamond wire. By using a diamond wire winding device... One end of the diamond wire is wound around one of the fixing screws 20 on the winding wheel 19. After tightening the fixing screw 20, the fixing screw 20 presses and fixes one end of the diamond wire. Then, the diamond wire is evenly wound around the winding wheel 19. Then, the diamond wire is wound around the tension wheel 25, the drive wheel 5, the drive wheel 5 and the tension wheel 25 in sequence. The diamond wire between the two drive wheels 5 will be passed through the two vacuum tubes 6. Finally, the other end of the diamond wire is wound around another fixing screw 20. After tightening the fixing screw 20, the fixing screw 20 presses and fixes the other end of the diamond wire, thus completing the assembly of the diamond wire.

[0020] During the cutting of photovoltaic silicon, the control panel 4 controls two sets of stepper motors to operate synchronously, driving the two drive wheels 5 to rotate. The drive wheels 5 drive the diamond wire to rotate on the two tension wheels 25, the two drive wheels 5 and the winding wheel 19. The stepper motor drives the drive wheels 5 to rotate back and forth, causing the diamond wire to rotate back and forth. During this process, the diamond wire drives the winding wheel 19 to rotate. When the winding wheel 19 rotates, it will move horizontally forward or backward on the first lead screw 17, realizing that the diamond wire is evenly wound on the winding wheel 19 and realizing the stable rotation of the diamond wire.

[0021] After the diamond wire rotates stably, the hydraulic rod 2 drives the mounting base 3 to move vertically downward as a whole. The diamond wire between the two drive wheels 5 cuts the photovoltaic silicon fixed on the base 1, thus realizing the slicing of photovoltaic silicon.

[0022] During this process, silicon powder adheres to the diamond wire between the two drive wheels 5, and the silicon powder-coated diamond wire enters the dust collection cylinder 6. The first motor 13 operates, driving the rotor to rotate at high speed. The rotor drives the fan blades 14 to rotate at high speed, causing the air inside the exhaust box 11, dust collection box 9, and the two dust collection cylinders 6 to be instantly discharged from the exhaust slot 12. A pressure difference exists between the exhaust box 11, dust collection box 9, and the two dust collection cylinders 6 and the outside environment. Under the action of this pressure difference, the silicon powder adhering to the diamond wire, along with the air, is sucked into the dust collection cylinder 6. Then, it enters the dust collection box 10 of the dust collection box 9 through the suction pipe 8. The dust is intercepted by the filter plate on the side wall of the dust collection box 10, and the clean air is discharged from the exhaust slot 12. This achieves the cleaning of the silicon powder adhering to the diamond wire. This structure can clean the surface of the diamond wire, preventing silicon powder from adhering to the diamond wire and reducing its cutting ability, thus improving the cleanliness and cutting ability of the diamond wire.

[0023] Please see Figure 1As shown, the mounting base 3 has a movable groove 21, and a second lead screw 22 is rotatably mounted on the inner wall of the movable groove 21. The threads on the second lead screw 22 are symmetrically opposite in direction. A damping wheel 23 is mounted on one end of the second lead screw 22. Two movable blocks 24 are symmetrically assembled in the movable groove 21, and a tensioning wheel 25 is rotatably mounted on the movable block 24. During operation, the existing diamond wire winding device has difficulty adjusting the tension of the diamond wire during the winding process, resulting in poor adjustability of the diamond wire tension. After the diamond wire is assembled, the damping wheel 23 is rotated to drive the second lead screw 22 to rotate. There is friction between the damping wheel 23 and the side wall of the mounting base 3, which can lock the second lead screw 22. The second lead screw 22 drives the two moving blocks 24 on it to move synchronously in opposite directions. The two moving blocks 24 drive the two tensioning wheels 25 to move synchronously in opposite directions. The two tensioning wheels 25 spread the diamond wire, so that the tensioning wheels 25 are tightened, thus achieving the tensioning of the diamond wire, which is beneficial to improving the adjustability of the diamond wire tension.

[0024] Working principle: In the process of slicing photovoltaic silicon, existing diamond wire winding devices generate silicon powder, some of which adheres to the diamond wire. Because the silicon powder adhering to the diamond wire cannot be cleaned, the cutting ability of the diamond wire decreases, resulting in poor wire cleanliness and affecting its cutting performance. To address this, one end of the diamond wire is wound around one of the fixing screws 20 on the winding wheel 19, and then the fixing screw 20 is tightened. The fixing screw 20 presses and fixes one end of the diamond wire. The diamond wire is then evenly wound around the winding wheel 19, and then sequentially wound around the tension wheel 25, the drive wheel 5, the drive wheel 5, and the tension wheel 25. The diamond wire between the two drive wheels 5 is threaded through the two vacuum tubes 6. Finally, the other end of the diamond wire is wrapped around another fixing screw 20, and then the fixing screw 20 is tightened. The fixing screw 20 presses and secures the other end of the diamond wire, thus assembling the diamond wire. During the cutting of photovoltaic silicon, the control panel 4 controls two sets of stepper motors to operate synchronously, driving the two drive wheels 5 to rotate. The drive wheels 5 drive the diamond wire to rotate on the two tension wheels 25, the two drive wheels 5, and the winding wheel 19. The stepper motors drive the drive wheels 5 to rotate reciprocally, causing the diamond wire to rotate reciprocally. During this process, the diamond wire drives the winding wheel 19 to rotate. During operation, the first lead screw 17 moves horizontally forward or backward, ensuring the diamond wire is evenly wound onto the winding wheel 19 and achieving stable rotation of the diamond wire. After stable rotation, the hydraulic rod 2 drives the mounting base 3 to move vertically downward, and the diamond wire between the two drive wheels 5 cuts the photovoltaic silicon fixed on the base 1, achieving slicing of the photovoltaic silicon. During this process, silicon powder adheres to the diamond wire between the two drive wheels 5, and the diamond wire with silicon powder enters the dust collection cylinder 6. The first motor 13 operates, driving the rotor to rotate at high speed, and the rotor drives the fan blades 14 to rotate at high speed, causing the exhaust box 11, dust collection box 9, and... The air inside the two vacuum tubes 6 is instantly discharged from the exhaust channel 12. There is a pressure difference between the exhaust box 11, the vacuum box 9, and the two vacuum tubes 6 and the outside. Under the action of the pressure difference, the silicon powder attached to the diamond wire and the air are sucked into the vacuum tube 6 together, and then enter the vacuum box 10 of the vacuum box 9 through the vacuum pipe 8. The dust is intercepted by the filter plate on the side wall of the vacuum box 10, and the clean air is discharged from the exhaust channel 12. This realizes the cleaning of the silicon powder attached to the diamond wire. This structure can clean the surface of the diamond wire, avoid silicon powder adhering to the diamond wire and causing a decrease in the diamond wire cutting ability, which is conducive to improving the cleanliness of the diamond wire and improving the cutting ability of the diamond wire.Existing diamond wire winding devices struggle to adjust the tension of the diamond wire during winding, resulting in poor adjustability. By rotating the damping wheel 23 after the diamond wire is assembled, the second lead screw 22 is rotated. Friction between the damping wheel 23 and the side wall of the mounting base 3 locks the second lead screw 22. The second lead screw 22 then drives two moving blocks 24 to move synchronously in opposite directions. These two moving blocks 24, in turn, drive two tensioning wheels 25 to move synchronously in opposite directions. The tensioning wheels 25 spread the diamond wire, tightening it and improving the adjustability of the diamond wire tension.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
