Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically a high-efficiency cooling device for the production of single-crystal silicon square rods. Background Technology

[0002] Monocrystalline silicon square rods are an important material used in the semiconductor industry to produce key components such as solar cells, integrated circuits, and optoelectronic components. Monocrystalline silicon square rods are usually pulled from molten silicon through high-temperature melting and crystal pulling processes. In the production process of monocrystalline silicon square rods, the silicon rods usually need to go through multiple processes such as cutting and grinding.

[0003] In the existing process of cutting monocrystalline silicon rods, the wire breakage rate is the main factor affecting production. As the diameter of the silicon rod increases, the contact area between the steel wire and the silicon rod increases, as does the friction length between them. Since the steel wire generates heat when cutting monocrystalline silicon rods, if it is not cooled in time, it will affect the mechanical strength of the steel wire and may even lead to breakage. The increase in cutting area also increases the amount of silicon powder during the cutting process. A large amount of silicon powder will adhere between the diamond abrasive grains on the surface of the steel wire, which will reduce the cutting ability of the steel wire and affect the cutting efficiency. Moreover, the silicon powder adhering to the surface of the steel wire also affects the heat dissipation of the steel wire, which will also reduce the cutting ability of the steel wire and increase the risk of wire breakage. Secondly, in traditional cutting, a large amount of water is sprayed for cooling, which wastes resources and increases costs. Utility Model Content

[0018] This invention, through the combination of a water pump and a collection plate, avoids a large waste of water resources. During cutting, the wastewater cooled by the sprayed water flows downward into the drainage trough. The wastewater entering the drainage trough is first filtered by a filter screen. The filtered water then flows downward into the collection tank for recycling, saving water resources.

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.

[0032] like Figures 1 to 11 As shown, this utility model provides a high-efficiency cooling device for the production of monocrystalline silicon square rods, including a device body 1. A U-shaped connecting plate 2 is fixedly connected to one side of the inner cavity of the device body 1. A U-shaped output plate 3 is provided on one side of the U-shaped connecting plate 2. An output groove 4 is formed on the edge of the U-shaped connecting plate 2 near the U-shaped output plate 3. A rack 5 is installed on one side of the inner cavity of the output groove 4. A water tank 6 is installed on the side of the U-shaped connecting plate 2 away from the U-shaped output plate 3. An L-shaped water pipe 7 is installed on one side of the water tank 6. A connecting pipe 9 is installed at the end of the L-shaped water pipe 7 away from the water tank 6. One end of the tube 7 is equipped with a telescopic tube 10. The end of the telescopic tube 10 away from the connecting tube 9 is equipped with a connecting tube 11. The outer wall of the connecting tube 11 away from the telescopic tube 10 is fitted with a connecting rod 12. The top of the connecting rod 12 is fixedly connected to an L-shaped connecting rod 13, and the end of the L-shaped connecting rod 13 away from the connecting rod 12 is fixedly connected to a U-shaped output plate 3. The top of the connecting rod 12 away from the L-shaped connecting rod 13 is fixedly connected to an output block 14. The side of the output block 14 away from the connecting rod 12 is fixedly connected to an output rod 15, and the output rod 15 slides in the output slot 4.

[0033] The output rod 15 is rotatably connected to a rotating rod 16. One end of the rotating rod 16 passes through the output rod 15 and is fixedly connected to a gear 17. The gear 17 meshes with the rack 5. The output block 14 is rotatably connected to a rotating rod 19. One end of the rotating rod 19 is fixedly connected to a gear 20. The output rod 15 and the rotating rod 19 are both fixedly connected to bevel gears 18 at their relatively close ends. The two bevel gears 18 mesh inside the output block 14. The end of the connecting rod 12 away from the connecting pipe 11 is fixedly connected to an annular cleaning box 21.

[0034] One end of the connecting pipe 11 away from the telescopic pipe 10 passes through the L-shaped connecting rod 13 and is fixedly connected to the annular cleaning box 21 and the water outlet pipe 22. Two rotating rings 23 are rotatably connected to both sides of the interior of the annular cleaning box 21. A connecting rod 24 is fixedly connected between the two rotating rings 23. An annular rack 25 is fixedly connected to one side of the outer wall of one rotating ring 23, and the annular rack 25 is meshed with the gear 20. Cleaning brushes 26 are evenly distributed and fixedly connected through the middle of the two rotating rings 23.

[0035] Using the above scheme: water flow is transmitted through L-shaped water pipe 7 to connecting pipe 9 and telescopic pipe 10, and then through telescopic pipe 10 to connecting pipe 11 and outlet pipe 22. Water flow is then transmitted through outlet pipe 22 to annular cleaning box 21. The cutting line is set to pass through the middle of annular cleaning box 21. When U-shaped output plate 3 descends, output rod 15 is driven to descend through L-shaped connecting rod 13.

[0036] At this time, the output rod 15 will slide in the output slot 4, and the gear 17 meshes with the rack 5 to make the gear 17 rotate. When the gear 17 rotates, it drives the rotating rod 16 and the bevel gear 18 to rotate. The bevel gear 18, which is fixedly connected to one end of the rotating rod 19, meshes with each other to make the rotating rod 19 rotate. This drives the gear 20 to rotate and mesh with the ring rack 25 to make the rotating ring 23 on one side of the inner wall of the ring cleaning box 21 rotate. When the rotating ring 23 on one side rotates, it drives the rotating ring 23 on the other side of the inner wall of the ring cleaning box 21 to rotate through the connecting rod 24. When the two rotating rings 23 rotate, they will drive the cleaning brush 26 to rotate to clean the cutting wire passing through the ring cleaning box 21. At this time, the water flow will also be in the ring cleaning box 21. The water spray can cool the cutting wire. At the same time, the cleaning brush 26 can also clean the silicon powder that should not be attached to the cutting wire, so as to avoid the silicon powder from being attached to the cutting wire and affecting the heat dissipation of the cutting wire, which will also reduce the cutting ability of the steel wire and increase the risk of wire breakage.

[0037] like Figures 1 to 11As shown, a collection box 29 is installed inside the device body 1, a water pump 27 is installed at the bottom of the water tank 6, a water pump 28 is fixedly connected to the end of the water pump 27 away from the water tank 6, and the water pump 28 passes through the device body 1 and the collection box 29. Two drainage grooves 30 are opened at the top of the inner cavity of the device body 1, and a collection plate 31 is installed between the two drainage grooves 30 and the collection box 29, and the collection plate 31 passes through the device body 1 and is slidably connected.

[0038] Two collection plates 31 are connected through the middle and a collection trough 32 is provided, and the collection trough 32 corresponds to the drainage trough 30. The inner walls of the two collection troughs 32 are fixedly connected with filter screens 33, and the filter screens 33 correspond to the collection troughs 32.

[0039] An annular connecting plate 34 is fixedly connected to the outer wall of the connection part between the telescopic pipe 10 and the connecting pipe 2 11. Four telescopic rods 35 are fixedly connected to the top of the annular connecting plate 34, and the end of the telescopic rod 35 away from the annular connecting plate 34 is fixedly connected to the U-shaped connecting plate 2.

[0040] The outer wall of the L-shaped water pipe 7 is fitted with a clamp 8, and the clamp 8 is installed on one side of the outer wall of the U-shaped connecting plate 2.

[0041] Two collection boxes 29 are fixedly connected to the side of the water tank 6 near the U-shaped connecting plate 2. The collection boxes 29 pass through the U-shaped connecting plate 2 and are fixedly connected. The collection boxes 29 are set in an inclined state to always maintain the corresponding cutting line.

[0042] Using the above solution: the wastewater after being cooled by water spray during cutting will flow downward into the drainage trough 30. The wastewater entering the drainage trough 30 will first pass through the filter screen 33 to filter the wastewater. The filtered water will then flow downward into the collection box 29 for recycling to save water resources. When the filter screen 33 has been used for a long time, the surface will collect the filtered impurities. At this time, pull the collection plate 31 to remove the collection plate 31 from the device body 1 to clean the impurities collected after the filter screen 33 is filtered, which can prevent the filter screen 33 from clogging and affecting the filtration effect.

[0043] While the U-shaped output plate 3 moves, the water pump 27 is started to draw coolant from the collection box 29 through the water pipe 28 and discharge it through the collection box 29 to spray and cool the cut part.

[0044] like Figures 1 to 11As shown, a connecting groove 36 is provided through the middle of the U-shaped connecting plate 2, and a connecting groove 39 is provided in the upper part of the interior of the U-shaped connecting plate 2. Threaded rods 37 are rotatably connected to the inner cavities of both connecting grooves 36, and the top of the threaded rods 37 passes through the connecting groove 39 and is rotatably connected. Connecting blocks 38 are threadedly connected to the outer walls of both threaded rods 37, and the connecting blocks 38 slide in the connecting grooves 36 and are fixedly connected to the U-shaped output plate 3. Synchronous pulleys 41 are fixedly connected to the outer walls of the inner cavities of both threaded rods 37 in the connecting grooves 39, and synchronous belts 42 are sleeved on the outer walls of the two synchronous pulleys 41.

[0045] A motor 40 is installed through and mounted on one side of the top of the U-shaped connecting plate 2, and the output end of the motor 40 is fixedly connected to the threaded rod 37 on one side.

[0046] Two viewing windows 43 are installed on the front side of the device body 1, through which the internal working status of the device body 1 can be viewed.

[0047] The above scheme is adopted: by turning on the motor 40, the threaded rod 37 on one side is driven to rotate, which drives the synchronous pulley 41 and the synchronous belt 42 to rotate, which in turn drives the threaded rod 37 on the other side to rotate. When the threaded rod 37 rotates, the connecting block 38 will slide downward in the connecting groove 36. The movement of the connecting groove 36 drives the U-shaped output plate 3 to move downward and the cutting line to cut the monocrystalline silicon rod.

[0048] Working principle and usage process of this utility model:

[0049] During operation, the motor 40 is first turned on to drive the threaded rod 37 on one side to rotate, which in turn drives the synchronous pulley 41 and synchronous belt 42 to rotate, which in turn drives the threaded rod 37 on the other side to rotate. When the threaded rod 37 rotates, the connecting block 38 slides downward in the connecting groove 36. The movement of the connecting groove 36 drives the U-shaped output plate 3 to move downward, and the cutting line cuts the monocrystalline silicon rod. At the same time as the U-shaped output plate 3 moves, the water pump 27 is started to draw coolant from the collection box 29 through the water pipe 28 and discharge it through the collection box 29 to spray and cool the cut part. At the same time, the water flow is also transmitted to the L-shaped water pipe 7, and then through the L-shaped water pipe 7 to the connecting pipe 9 and the telescopic pipe 10. Then, through the telescopic pipe 10, the water flow is transmitted to the connecting pipe 11 and the outlet pipe 22. Through the outlet pipe 22, the water flow is transmitted to the annular cleaning box 21. The cutting line is set to pass through the middle of the annular cleaning box 21. When the U-shaped output plate 3 descends, the output rod 15 is driven to descend through the L-shaped connecting rod 13. At this time, the output... The rod 15 slides within the output slot 4, while gear 17 meshes with rack 5 to rotate. When gear 17 rotates, it drives rotating rod 16 and bevel gear 18 to rotate. Bevel gear 18, which is fixedly connected to one end of rotating rod 29, meshes with each other to rotate rod 29, causing gear 20 to rotate and mesh with ring rack 25, causing rotating ring 23 on one side of the inner wall of ring cleaning box 21 to rotate. When rotating ring 23 on one side rotates, it drives rotating ring 23 on the other side of the inner wall of ring cleaning box 21 to rotate via connecting rod 24. When both rotating rings 23 rotate, they drive cleaning brush 26 to rotate and clean the cutting wire passing through ring cleaning box 21. At this time, water also flows in ring cleaning box 21. By spraying, the cutting wire can be cooled. At the same time, cleaning brush 26 can also clean the silicon powder that should not adhere to the cutting wire, preventing silicon powder from adhering to the cutting wire and affecting heat dissipation, reducing the cutting ability of the wire, and increasing the risk of wire breakage.

[0050] Wastewater cooled by water spraying during cutting flows downward into the drainage trough 30. The wastewater entering the drainage trough 30 is first filtered by the filter screen 33. The filtered water then flows downward into the collection box 29 for recycling, saving water resources. After the filter screen 33 has been used for a long time, impurities will be collected on its surface. At this time, the collection plate 31 is pulled out from the device body 1 to clean the impurities collected by the filter screen 33, which can prevent the filter screen 33 from clogging and affecting the filtration effect.
