[0002] Single crystal silicon square rods are important materials used in the semiconductor industry to produce key components such as solar cells, integrated circuits, and optoelectronic elements. Single crystal silicon square rods are usually pulled from silicon melt through high-temperature melting and crystal pulling processes. During the production of single crystal 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 and chopping single crystal silicon rods, the wire breakage rate of the steel wire 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 and the friction length between them also increases. Since the steel wire generates heat when cutting the single crystal silicon rod, if it is not cooled in time, it will affect the mechanical strength of the steel wire, and in severe cases it will cause wire breakage. The increase in the cutting area also increases the amount of silicon powder in the cutting process, and a large amount of silicon powder will adhere to the diamond sand grains on the surface of the steel wire, which will reduce the cutting ability of the steel wire and affect the cutting efficiency. In addition, the silicon powder attached 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 will be sprayed for cooling, and spraying a large amount of water will cause resource waste and increase costs. Summary of the invention

The output block 14 is internally rotatably connected with a rotating rod 2 19, one end of which is fixedly connected with a gear 2 20.

When the rotating ring 23 on one side rotates, the rotating ring 23 on the other side of the inner wall of the annular cleaning box 21 is driven to rotate through the connecting rod 2 24.

[0038] The middle of the two collecting plates 31 is penetrated and provided with a collecting groove 32, and the collecting groove 32 corresponds to the drainage groove 30, and the inner walls of the two collecting grooves 32 are fixedly connected with a filter screen 33, and the filter screen 33 corresponds to the collecting groove 32;

[0039] The outer wall of the connection part between the telescopic tube 10 and the connecting tube 2 11 is fixedly connected with an annular connecting plate 34, and the top of the annular connecting plate 34 is fixedly connected with four telescopic rods 35, and one end of the telescopic rods 35 away from the annular connecting plate 34 is fixedly connected with the U-shaped connecting plate 2;

[0040] The outer wall of the L-shaped water pipe 7 is provided 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 collecting boxes 29 are fixedly connected to one side of the water tank 6 close to the U-shaped connecting plate 2, and the collecting boxes 29 penetrate the U-shaped connecting plate 2 and are fixedly connected. The collecting boxes 29 are set to an inclined state to always maintain the corresponding cutting line.

[0042] The above scheme is adopted: during cutting, the sewage after water spray cooling will flow downward into the drainage groove 30, and the sewage entering the drainage groove 30 will first pass through the filter 33 to filter the sewage, and the filtered water will flow downward into the collection box 29 for recycling to save water resources. When the filter 33 is used for a long time, the surface will collect the filtered impurities. At this time, the collection plate 31 is pulled out of the device body 1 to clean the impurities collected by the filter 33 after filtering, which can prevent the filter 33 from being blocked and affecting the filtering effect.

[0043] When the U-shaped output plate 3 moves, the water pump 27 is started to extract the coolant in the collection box 29 through the water extraction pipe 28 and discharge it through the collection box 29 to spray and cool the cut parts.

[0044] like Figures 1 to 11As shown, a connecting groove 1 36 is penetrated and opened in the middle of the U-shaped connecting plate 2, a connecting groove 2 39 is opened in the upper inner part of the U-shaped connecting plate 2, the inner cavities of the two connecting grooves 1 36 are both rotatably connected with threaded rods 37, and the tops of the threaded rods 37 penetrate the connecting groove 2 39 and are rotatably connected, the outer walls of the two threaded rods 37 are both threadedly connected with connecting blocks 38, and the connecting blocks 38 slide in the connecting groove 1 36 and are fixedly connected to the U-shaped output plate 3, the outer walls of the two threaded rods 37 located in the inner cavities of the connecting groove 2 39 are both fixedly connected with synchronous wheels 41, and the outer walls of the two synchronous wheels 41 are sleeved with synchronous belts 42;

[0045] A motor 40 is passed through and installed 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 a threaded rod 37 on one side;

[0047] The above scheme is adopted: by turning on the motor 40 to drive the threaded rod 37 on one side to rotate, driving the synchronous wheel 41 and the synchronous belt 42 to rotate, and driving 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 1 36, and the movement of the connecting groove 1 36 drives the U-shaped output plate 3 to move downward along the cutting line to cut the single crystal silicon rod.

[0048] The working principle and use process of the present invention:

[0049] When working, first start the motor 40 to drive the threaded rod 37 on one side to rotate, driving the synchronous wheel 41 and the synchronous belt 42 to rotate and drive 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 1 36, and the movement of the connecting groove 1 36 drives the U-shaped output plate 3 to move the cutting line downward to cut the single crystal silicon rod. When the U-shaped output plate 3 moves, the water pump 27 is started to extract the coolant in the collection box 29 through the water pumping pipe 28 and discharge it through the collection box 29 to spray and cool the cut part. At the same time, the water flow will also be transmitted to the L-shaped water pipe 7, and then transmitted to the connecting pipe 1 9 and the telescopic pipe 10 through the L-shaped water pipe 7, and then transmitted to the connecting pipe 2 11 and the water outlet pipe 22 through the telescopic pipe 10, and the water flow is transmitted to the annular cleaning box 21 through the water outlet pipe 22. 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 will slide in the output groove 4, and the gear 17 will mesh with the rack 5 to make the gear 17 rotate. When the gear 17 rotates, it will drive the rotating rod 16 and the bevel gear 18 to rotate. The bevel gear 18 fixedly connected to one end of the rotating rod 2 19 will mesh with each other to make the rotating rod 2 19 rotate, driving the gear 2 20 to rotate and mesh with the annular rack 25 to make the rotating ring 23 on one side of the inner wall of the annular cleaning box 21 rotate. When the rotating ring 23 on one side rotates, the connecting rod 24 will drive the rotating ring 23 on the other side of the inner wall of the annular cleaning box 21 to rotate. When the two rotating rings 23 rotate, the cleaning brush 26 will be driven to rotate to clean the cutting line passing through the annular cleaning box 21. At this time, the water flow will also be in the annular cleaning box 21. The cutting line can be cooled by spraying. At the same time, the cleaning brush 26 can be used to clean the silicon powder that is attached to the cutting line to prevent the silicon powder from adhering to the cutting line and affecting the heat dissipation of the cutting line, which will also reduce the cutting ability of the steel line and increase the risk of breaking the steel line.

[0050] During cutting, the sewage cooled by water spray will flow downward into the drainage trough 30. The sewage entering the drainage trough 30 will first pass through the filter 33 to filter the sewage. The filtered water will flow downward into the collection box 29 for recycling to save water resources. When the filter 33 has been used for a long time, the surface will collect 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 by the filter 33 after filtering, which can prevent the filter 33 from being blocked and affecting the filtering effect.
