Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing equipment, in particular to a tensioning device for a cutting line. Background Art

[0002] A wire cutting device is used in the processing factory for single crystal silicon square bars. It is a device that uses high-speed diamond wire to cut single crystal silicon square bars under precise control. It is mainly used in the production of semiconductors, photovoltaics and high-precision electronic components. The device pulls the diamond wire along a predetermined trajectory on the surface of the silicon square bar so that the silicon square bar is gradually cut into thin slices or desired shapes. The high hardness and sharpness of the diamond wire enable it to effectively cut single crystal silicon materials with higher hardness. The grinding force generated during the cutting process is small, thereby reducing thermal damage and mechanical stress of the material, ensuring that the surface of the silicon wafer is flat, smooth and high-precision.

[0003] In the traditional square cutting process, a fixed cutting speed and a fixed tensioning force are usually used, and the tensioning force of the cutting wire cannot be adjusted during the cutting process; the entry section is the area where the cutting wire contacts the material for the first time when the cutting wire is cutting. If the tensioning force is too high, the cutting wire will exert too much pressure on the surface of the material. Excessive entry force may cause surface cracks or irregular cutting marks when the cutting wire cuts into the material, affecting the cutting quality or even destroying the structure of the material. At the same time, when the cutting wire successfully cuts into the material and enters the cutting section, the cutting process needs to maintain appropriate tension to ensure a stable cutting effect. The cutting wire of the cutting section needs to maintain a certain tension so as to exert continuous and uniform cutting pressure on the material. Too loose will cause the cutting wire to fail to effectively cut into the material, affecting the cutting effect. Secondly; in the return line stage, the cutting wire is usually in a lower load state. If it continues to remain tight, it may accidentally contact the surface of the single crystal silicon square rod, causing secondary damage. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention prevents excessive tension from being applied to the surface of the monocrystalline silicon square rod by arranging the coordination of structures such as a motor and a U-shaped output plate, thereby preventing the cutting line from applying excessive pressure to the surface of the monocrystalline silicon square rod, causing surface cracks or irregular cutting marks when the cutting line cuts into the material. The motor is turned on to drive the threaded rod to rotate, and the rotation of the threaded rod drives the connecting block to slide downward in the installation groove, and the U-shaped output plate is driven to slide downward by the connecting block to cut the monocrystalline silicon square rod through the cutting line. When the U-shaped output plate slides downward, the cutting line first contacts the monocrystalline silicon square rod and enters the cutter entry section. At this time, the cutting line is in a relaxed state to cut the monocrystalline silicon square rod, thereby preventing excessive tension from being applied to the surface of the monocrystalline silicon square rod, causing surface cracks or irregular cutting marks when the cutting line cuts into the material.

[0018] The present invention can prevent the cutting line from being too loose, which may cause the cutting line to be unable to effectively cut into the material and affect the cutting effect, by arranging the cooperation of structures such as the sliding plate and the mounting block. When the U-shaped output plate moves downward for cutting, the limit block 2 will slide downward in the limit groove 2, and at the same time, the gear 2 will mesh with the rack 2 to rotate the rotating rod. When the rotating rod rotates, it will drive the gear 1 to rotate, so that the gear 1 will mesh with the rack 1 to make the sliding plate slide in the tooth plate groove. When the sliding plate moves, the pushing plate will push the mounting block to slide in the tensioning groove. When the mounting block slides in the tensioning groove, it will drive the connecting rod and the tensioning wheel to move. The movement of the tensioning wheel can drive the cutting line to be tightened. At this time, the cutting line has just entered the cutting section from the entry section. The cutting line is tightened in the cutting section to cut the monocrystalline silicon square rod, which can prevent the cutting line from being too loose, which may cause the cutting line to be unable to effectively cut into the material and affect the cutting effect.

[0019] The present invention prevents the cutting line from being too tight in the loop section, which may accidentally contact the surface of the single crystal silicon square rod and cause secondary damage, by arranging the cooperation of structures such as the sliding plate and the mounting block. The motor is turned on to reverse the output rod and drive the two threaded rods to reverse at the same time. At this time, the connecting block drives the U-shaped output plate to move upward. When the U-shaped output plate moves upward, the gear 2 is meshed with the limit block 2 to drive the rotating rod to reverse, and the gear 1 is reversed at the same time. When the gear 1 reverses, it is meshed with the rack 1 to reset the sliding plate. At the same time, the mounting block, the limit block 1, the connecting rod and the tension wheel are reset by the sliding plate. The compression of the tension wheel on the cutting line is cancelled by resetting the tension wheel, so that the cutting line is released from the tight state, and the cutting line is prevented from being too tight in the loop section, which may accidentally contact the surface of the single crystal silicon square rod and cause secondary damage.

[0034] A toothed plate groove 11 is provided at the bottom of the output groove 10 and the tensioning groove 4, a sliding plate 12 is slidably connected inside the toothed plate groove 11, a rack 13 is fixedly connected to one side of the top of the sliding plate 12, a push plate 14 is fixedly connected to the side of the top of the sliding plate 12 away from the rack 13, and the push plate 14 cooperates with the sliding plate 12, a rotating rod 15 is passed through and rotatably connected to one side of the U-shaped output plate 3, one end of the rotating rod 15 is fixedly connected to a gear 16, and the gear 16 is meshed with the rack 13, a gear 2 17 is fixedly connected to the outer wall of the rotating rod 15 away from the gear 16, and the end of the rotating rod 15 away from the gear 16 is rotatably connected to a limited block 2 18;

[0035] The top of the sliding plate 12 is located at both ends of the rack 13 and is provided with tooth block grooves 19, and a tooth block 22 is slidably connected inside the tooth block groove 19. Two sliding rods 20 are fixedly connected to the inner cavity of the tooth block groove 19 on one side, and the sliding rod 20 passes through the tooth block 22. The outer walls of the two tooth blocks 22 are provided with springs 21, and the springs 21 cooperate with the tooth blocks 22.

[0036] A connecting groove 23 is formed on one side of the U-shaped connecting plate 2, and a second rack 24 is fixedly connected to one side of the inner cavity of the connecting groove 23, and the second rack 24 is meshed and connected with the second gear 17;

[0037] A second limiting groove 25 is provided on one side of the inner cavity of the connecting groove 23 close to the second rack 24, and the second limiting groove 25 cooperates with the second limiting block 18;

[0038] The two sides of the U-shaped connecting plate 2 are penetrated and provided with mounting grooves 26, the inner cavities of the two mounting grooves 26 are rotatably connected with threaded rods 27, the outer walls of the two threaded rods 27 are threadedly connected with connecting blocks 28, and one side of the connecting block 28 is fixedly connected to the U-shaped output plate 3, and the top of the U-shaped connecting plate 2 is provided with an output groove 29;

[0039] The tops of the two threaded rods 27 pass through the second output groove 29 and are rotatably connected. The outer walls of the two threaded rods 27 located inside the second output groove 29 are fixedly connected with synchronous wheels 32. The outer walls of the two synchronous wheels 32 are sleeved with synchronous belts 33.

[0040] A motor 30 is passed through and installed on one side of the top of the U-shaped connecting plate 2 , an output end of the motor 30 is fixedly connected to an output rod 31 , and one end of the output rod 31 away from the motor 30 is fixedly connected to a threaded rod 27 on one side.

[0041] The above solution is adopted: the U-shaped output plate 3 slides downward so that the cutting line 35 first contacts the single crystal silicon square rod and enters the cutting section. At this time, the cutting line 35 is in a relaxed state to cut the single crystal silicon square rod, so as to avoid excessive tension. The cutting line will apply excessive pressure to the surface of the single crystal silicon square rod, resulting in surface cracks or irregular cutting marks when the cutting line cuts into the material;

[0042] At the same time, when the U-shaped output plate 3 moves downward for cutting, the limit block 2 18 will slide downward in the limit groove 25, and the gear 2 17 will mesh with the rack 2 24 to rotate the rotating rod 15. When the rotating rod 15 rotates, the gear 16 will be driven to rotate, so that the gear 16 will mesh with the rack 13 to make the sliding plate 12 slide in the tooth plate groove 11. When the sliding plate 12 moves, the mounting block 6 is pushed to slide in the tensioning groove 4 through the push plate 14. At the same time, the limit block 17 will slide in the limit groove 15. When the mounting block 6 slides in the tensioning groove 4, it will drive the connecting rod 8 and the tension wheel 9 to move. The movement of the tension wheel 9 can drive the cutting line 35 to be tightened. At this time, the cutting line 35 has just entered the cutting section from the cutting section. In the cutting section, the cutting line 35 is tightened to cut the single crystal silicon square rod, which can avoid the cutting line 35 being too loose, which will cause the cutting line 35 to fail to effectively cut into the material, affecting the cutting effect.

[0043] When the cutting is completed and the looping stage is entered, the cutting line 35 is in a taut state. The motor 30 is turned on to reverse the output rod 31 and drive the two threaded rods 27 to reverse at the same time. At this time, the connecting block 28 will drive the U-shaped output plate 3 to move upward. When the U-shaped output plate 3 moves upward, the gear 2 17 is meshed with the limit block 2 18 to drive the rotating rod 15 to reverse, and the gear 1 16 is reversed. When the gear 1 16 is reversed, it is meshed with the rack 13 to reset the sliding plate 12. At the same time, the mounting block 6, the limit block 1 7, the connecting rod 8 and the tension wheel 9 are reset by the sliding plate 12. The resetting of the tension wheel 9 cancels the squeezing of the cutting line 35 by the tension wheel 9, so that the cutting line 35 is released from the taut state, and the taut state is released to prevent the cutting line 35 from being too tight in the loop section, which may accidentally contact the surface of the single crystal silicon square rod and cause secondary damage.

[0044] During cutting, when the gear 16 meshes with the rack 13 and drives the sliding plate 12 to a certain position, the gear 16 meshes with the tooth block 22 and drives the tooth block 22 to slide in the tooth block groove 19 while compressing the spring 21. At this time, the gear 16 is idle, so as to avoid the problem of excessive tension causing the cutting line 35 to break.

[0045] When the gear 16 is engaged with the rack 13 to drive the sliding plate 12 to reset to a certain position, the gear 16 is engaged with the tooth block 22 to drive the tooth block 22 to slide in the tooth block groove 19 and compress the spring 21. At this time, the gear 16 is idle to avoid the problem of the gear 16 and the rack 13 being stuck.

[0046] When the motor 30 is turned on, the output rod 31 drives the threaded rod 27 to rotate. When the threaded rod 27 rotates, the synchronous wheel 32 and the synchronous belt 33 are driven to rotate. The synchronous belt 33 drives the threaded rod 27 and the synchronous wheel 32 at the other end to rotate. The rotation of the threaded rod 27 drives the connecting block 28 to slide downward in the mounting groove 26. The sliding of the connecting block 28 drives the U-shaped output plate 3 to slide downward through the cutting line 35 to cut the single crystal silicon square rod.

[0047] like Figures 1 to 11 As shown, a material discharging rotating disk 36 is rotatably connected to the inner cavity of the device body 1 away from the U-shaped connecting plate 2, and two viewing windows 37 are penetrated and opened on the front side of the device body 1, through which the interior of the device body 1 can be observed;

[0048] Four wire wheels 34 are installed on one side of the U-shaped output plate 3 away from the second limit block 18, and cutting wires 35 are installed inside the four wire wheels 34;

[0049] A U-shaped baffle 38 is fixedly connected to the edge of the U-shaped output plate 3 close to the wire wheel 34 , and the cutting wire 35 can be blocked by the U-shaped baffle 38 to prevent the cutting wire 35 from being thrown out when a fault occurs.

[0050] The above scheme is adopted: the single crystal silicon square rod is placed on the material discharge rotating disk 36, and the material discharge rotating disk 36 can drive the single crystal silicon square rod to rotate and adjust the cutting position. The cutting situation of the single crystal silicon square rod can be seen through the visual window 37, and the cutting line 35 can be blocked by the U-shaped baffle 38 to prevent the cutting line 35 from being thrown out when a fault occurs, causing safety problems.

[0051] The working principle and use process of the present invention:

[0052] When it is necessary to cut the monocrystalline silicon square rod, first place the monocrystalline silicon square rod on the material discharging rotating disk 36, and then turn on the motor 30, so that the output rod 31 drives the threaded rod 27 to rotate, and when the threaded rod 27 rotates, it drives the synchronous wheel 32 and the synchronous belt 33 to rotate, and the synchronous belt 33 drives the threaded rod 27 and the synchronous wheel 32 at the other end to rotate, and the rotation of the threaded rod 27 drives the connecting block 28 to slide downward in the installation groove 26, and the sliding of the connecting block 28 drives the U-shaped output plate 3 to slide downward to cut the monocrystalline silicon square rod through the cutting line 35, and the U-shaped output plate 3 slides downward so that the cutting line 35 first contacts the monocrystalline silicon square rod and enters the cutting section. At this time, the cutting line 35 is in a relaxed state to cut the monocrystalline silicon square rod, so as to avoid excessive tension. The cutting line will apply excessive pressure on the surface of the monocrystalline silicon square rod, resulting in surface cracks or irregular cutting marks when the cutting line cuts into the material;

[0053] At the same time, when the U-shaped output plate 3 moves downward for cutting, the limit block 18 will slide downward in the limit groove 25, and the gear 17 will mesh with the rack 24 to rotate the rotating rod 15. When the rotating rod 15 rotates, the gear 16 will be driven to rotate, so that the gear 16 will mesh with the rack 13 to make the sliding plate 12 slide in the tooth plate groove 11. When the sliding plate 12 moves, the mounting block 6 is pushed to slide in the tensioning groove 4 through the push plate 14. At the same time, the limit block 17 slides in the limit groove 15. When the mounting block 6 slides in the tensioning groove 4, it drives the connecting rod 8 and the tensioning wheel 9 to move through the tensioning wheel 9. The movement can drive the cutting line 35 to be tightened. At this time, the cutting line 35 has just entered the cutting section from the cutting section. In the cutting section, the cutting line 35 is tightened to cut the single crystal silicon square rod, which can avoid the cutting line 35 being too loose, which will cause the cutting line 35 to fail to effectively cut into the material and affect the cutting effect. When the gear 16 is engaged with the rack 13 and drives the sliding plate 12 to a certain position, the gear 16 will be engaged with the tooth block 22 to drive the tooth block 22 to slide in the tooth block groove 19 and compress the spring 21 at the same time. At this time, the gear 16 is idling, which avoids the problem of excessive tensioning force causing the cutting line 35 to break;

[0054] When the cutting is completed and the line return stage is entered, the cutting line 35 is in a taut state. The motor 30 is turned on to reverse the output rod 31 and drive the two threaded rods 27 to reverse at the same time. At this time, the connecting block 28 drives the U-shaped output plate 3 to move upward. When the U-shaped output plate 3 moves upward, the gear 2 17 engages with the limit block 2 18 to drive the rotating rod 15 to reverse and reverse the gear 1 16. When the gear 1 16 reverses, it engages with the rack 1 13 to reset the sliding plate 12. At the same time, the sliding plate 12 drives the mounting block 6, the limit block 1 7, the connecting rod 8 and the tensioning wheel 9 to move. The cutting line 35 is reset by resetting the tension wheel 9 to cancel the squeezing of the tension wheel 9 on the cutting line 35, so that the cutting line 35 is released from the tight state, and the tight state is released to avoid the cutting line 35 being too tight in the loop section, which may accidentally contact the surface of the single crystal silicon square rod and cause secondary damage. When the gear 16 is engaged with the rack 13 to drive the sliding plate 12 to reset to a certain position, the gear 16 will be engaged with the tooth block 22 to drive the tooth block 22 to slide in the tooth block groove 19 and compress the spring 21 at the same time. At this time, the gear 16 is idling to avoid the problem of the gear 16 and the rack 13 being stuck.
