Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire cutting equipment for processing monocrystalline silicon rods, and in particular to a wire cutting equipment for processing monocrystalline silicon rods. Background Technology
[0002] The wire cutting equipment for monocrystalline silicon rods is a key piece of equipment for cutting monocrystalline silicon rods into thin slices. During the cutting process, the cutting wire moves at high speed, and the silicon rod is cut into thin slices by the grinding action of the cutting wire through the relative motion between the cutting wire and the monocrystalline silicon rod.
[0003] The screw is a key component that drives the monocrystalline silicon rod forward (i.e., provides the feed motion of the silicon rod relative to the cutting line). It converts rotational motion into linear motion through rotational motion, thereby precisely controlling the position movement of the silicon rod. During the cutting process of the monocrystalline silicon rod, a large amount of silicon debris is generated under the grinding action of the cutting line. When the debris falls into the screw, due to the very small thread clearance of the screw, the debris may get stuck between the threads. This will increase the friction of the screw during rotation, affect the smooth rotation of the screw, aggravate the wear of the screw, and thus shorten the service life of the screw. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wire cutting device for processing single-crystal silicon rods.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wire cutting device for processing single-crystal silicon rods, comprising a frame, two rotating shafts rotatably connected to the frame, guide wheels fixedly connected to the rotating shafts, a cutting wire commonly arranged on the two guide wheels, a nozzle fixedly connected to the frame, a slide rail slidably connected to the frame, a mounting plate slidably connected to the slide rail, a threaded rod rotatably connected to the slide rail via a bearing, a first motor fixedly connected to the slide rail, the threaded rod being driven to rotate by the first motor, and a cylinder fixedly connected to the frame. The piston rod of the cylinder is fixedly connected to the slide rail. Two sprockets are fixedly connected to the two rotating shafts, and the two sprockets are driven by a chain. A second motor is fixedly connected to the equipment frame, and one rotating shaft is driven to rotate by the second motor. A support block is fixedly connected to the slide rail. A protective structure is provided on the slide rail, mainly composed of a fixed frame. The fixed frame is fixedly connected to the support block, and a rotating rod is rotatably connected to the fixed frame. A protective cloth is fixedly connected to the rotating rod, and a connecting cylinder is fixedly connected to one end of the protective cloth. Two baffles are fixedly connected to the slide rail.
[0006] The aforementioned components achieve the following effects: The silicon rod is mounted on the mounting plate and supported on the support block. The output of the second motor is connected to the rotating shaft via a reducer and coupling. The second motor, model Y2-160m1-8, drives the rotating shaft to rotate. Under the action of the chain, the two rotating shafts rotate synchronously, which in turn drives the cutting wire through the guide wheel. The cylinder is activated; its piston rod drives the slide rail upwards until the cutting wire cuts the silicon rod. The nozzle is connected to external cutting fluid via a liquid pump, allowing the cutting fluid to be sprayed through the nozzle for cooling. The output of the first motor is connected via... The reducer and coupling are connected to the threaded rod. The first motor is model 17HS4401. Starting the first motor drives the threaded rod to rotate, which in turn moves the silicon rod through the mounting plate to a suitable cutting position. The connecting cylinder is installed on the mounting plate. The protective cloth can block the threaded rod to prevent debris from entering, and the two baffles can further protect the gaps on both sides of the protective cloth. This avoids the situation where debris may get stuck between the threads, increasing the friction of the screw during rotation, affecting the smooth rotation of the screw, aggravating the wear of the screw, and shortening the service life of the screw.
[0007] Preferably, two sliding rods are slidably inserted on the connecting cylinder, one end of the sliding rod is fixedly connected to a connecting plate, a locking rod is fixedly connected to the connecting plate, and slots are respectively opened on both sides of the mounting plate.
[0008] The effect achieved by the above components is as follows: by sliding the two sliding rods, the locking rod can be locked into the corresponding slot, and the connecting cylinder can be installed on the mounting plate to limit the movement of the connecting cylinder.
[0009] Preferably, two slide rods are slidably connected to the connecting cylinder, the slide rods are fixedly connected to the slide bar, and a first spring is fixedly connected to both slide rods.
[0010] The effect achieved by the above components is that when the locking rod is inserted into the slot, the first spring is in a stretched state, so the rebound force of the first spring acts on the slide rod, making the limiting more stable.
[0011] Preferably, two second springs are sleeved on the rotating rod, one end of the second spring is fixedly connected to the fixed frame, and the other end of the second spring is fixedly connected to the protective cloth.
[0012] The effect achieved by the above components is that when the protective cloth is pulled open, the two second springs are in a twisted state. Therefore, as the mounting plate moves and the mounting plate gets closer to the support block, the protective cloth is rolled up under the action of the rebound force of the two second springs.
[0013] Preferably, the mounting plate is provided with a mounting structure, which mainly consists of a mounting groove. The mounting groove is formed on the mounting plate, and a bolt is threaded into the mounting plate. One end of the bolt is rotatably connected to a limit block, and the limit block is slidably connected to the mounting groove.
[0014] The effect achieved by the above components is as follows: when the silicon rod is inserted into the mounting slot, the bolt is rotated, causing the limiting block to move downward, thereby clamping and limiting the silicon rod.
[0015] Preferably, a disc is fixedly connected to the mounting plate, the disc is threadedly connected to a bolt, the disc has several circular grooves, one end of the bolt is fixedly connected to a connecting block, and a circular rod is slidably inserted into the connecting block.
[0016] The effect achieved by the above components is that after clamping, the sliding rod can be inserted into the corresponding groove to limit the bolt position.
[0017] Preferably, a third spring is sleeved on the round rod, one end of the third spring is fixedly connected to the round rod, and the other end of the third spring is fixedly connected to the connecting block.
[0018] The effect achieved by the above components is that after the round rod is inserted into the round groove, the third spring is in a stretched state, so the rebound force of the third spring acts on the round rod, making the limit more stable.
[0019] Preferably, a rubber block is fixedly connected to both the mounting groove and the limiting block, and a plurality of ball bearings are provided on the support block.
[0020] The effects achieved by the above components are as follows: the two rubber blocks can prevent rigid contact from damaging the silicon rod, and the elasticity of the two rubber blocks can adapt to the gap between the circular grooves, and the ball bearings can make the movement of the silicon rod smoother.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a protective structure, the silicon rod is mounted on the mounting plate and supported on the support block. The output end of the second motor is connected to the rotating shaft through a reducer and a coupling. The model of the second motor is Y2-160m1-8. Starting the second motor can drive the rotating shaft to rotate. Under the action of the chain, the two rotating shafts rotate synchronously, which in turn drives the cutting wire to move through the guide wheel. The cylinder is started, and the piston rod of the cylinder drives the slide to rise until the cutting wire cuts the silicon rod. The nozzle is connected to the external cutting fluid through a liquid pump, and the cutting fluid can be sprayed out through the nozzle for cooling. However, the temperature drops. The output end of the first motor is connected to the threaded rod through a reducer and coupling. The model of the first motor is 17HS4401. Starting the first motor can drive the threaded rod to rotate, and then move the silicon rod through the mounting plate to move it to the appropriate cutting position. The connecting cylinder is installed on the mounting plate. The protective cloth can block the threaded rod to prevent debris from entering, and the two baffles can further protect the gaps on both sides of the protective cloth. This avoids the situation where debris may get stuck between the threads, which would increase the friction of the screw during rotation, affect the smooth rotation of the screw, aggravate the wear of the screw, and shorten the service life of the screw.

[0028] Example 1, such as Figure 1 and Figure 2 As shown, a wire cutting device for processing single-crystal silicon rods includes a frame 1, two rotating shafts 2 rotatably connected to the frame 1, guide wheels 3 fixedly connected to the rotating shafts 2, and a cutting wire 4 commonly provided on the two guide wheels 3. A nozzle 5 is fixedly connected to the frame 1, a slide rail 6 is slidably connected to the frame 1, a mounting plate 7 is slidably connected to the slide rail 6, a threaded rod 10 is rotatably connected to the slide rail 6 via a bearing, a first motor 11 is fixedly connected to the slide rail 6, and the threaded rod 10 is driven to rotate by the first motor 11. A cylinder 12 is fixedly connected to the frame 1, and the piston rod of the cylinder 12 is fixedly connected to the slide rail 6. Sprockets 13 are fixedly connected to the two rotating shafts 2 respectively, and the two sprockets 13 are driven to rotate by a chain 14. A second motor 15 is fixedly connected to the frame 1, and one rotating shaft 2 is driven to rotate by the second motor 15. A support block 16 is fixedly connected to the slide rail 6.
[0029] Reference Figure 3 and Figure 5A protective structure 8 is installed on the slide rail 6. The protective structure 8 mainly consists of a fixed frame 81, which is fixedly connected to the support block 16. A rotating rod 82 is rotatably connected in the fixed frame 81. A protective cloth 83 is fixedly connected to the rotating rod 82. A connecting cylinder 84 is fixedly connected to one end of the protective cloth 83. Two baffles 812 are fixedly connected on the slide rail 6. The silicon rod is installed on the mounting plate 7 and supported on the support block 16. The output end of the second motor 15 is connected to the rotating shaft 2 through a reducer and a coupling. The model of the second motor 15 is Y2-160m1-8. Starting the second motor 15 can drive the rotating shaft 2 to rotate. Under the action of the chain 14, the two rotating shafts 2 rotate synchronously, and then through the guide wheel 3 drives the cutting wire 4 to move, activating cylinder 12. The piston rod of cylinder 12 drives slide 6 to rise until the cutting wire 4 cuts the silicon rod. The nozzle 5 is connected to the external cutting fluid through a liquid pump, and the cutting fluid can be sprayed through the nozzle 5 for cooling. The output end of the first motor 11 is connected to the threaded rod 10 through a reducer and coupling. The first motor 11 is model 17HS4401. Activating the first motor 11 can drive the threaded rod 10 to rotate, which in turn moves the silicon rod through the mounting plate 7 to move it to the appropriate cutting position. The connecting cylinder 84 is installed on the mounting plate 7. The protective cloth 83 can block the threaded rod 10 to prevent debris from entering, and the two baffles 812 can block the two sides of the protective cloth 83. The side gaps are further protected to prevent debris from getting stuck between the threads, which would increase friction during screw rotation, affect smooth screw rotation, accelerate screw wear, and shorten screw life. Two sliding rods 85 are slidably inserted on the connecting cylinder 84. One end of each sliding rod 85 is fixedly connected to a connecting plate 86, and a locking rod 87 is fixedly connected to the connecting plate 86. Slots 88 are provided on both sides of the mounting plate 7. Sliding the two sliding rods 85 engages the locking rod 87 in the corresponding slots 88, allowing the connecting cylinder 84 to be mounted on the mounting plate 7 and limiting its position. Two sliding rods 89 are slidably connected to the connecting cylinder 84. 85 is fixedly connected. Two slide rods 89 are fixedly connected to a first spring 810. When the locking rod 87 is locked into the locking slot 88, the first spring 810 is in a stretched state. Therefore, the rebound force of the first spring 810 acts on the slide rod 89, making the limit more stable. Two second springs 811 are sleeved on the rotating rod 82. One end of the second spring 811 is fixedly connected to the fixed frame 81, and the other end of the second spring 811 is fixedly connected to the protective cloth 83. When the protective cloth 83 is pulled open, the two second springs 811 are in a twisted state. Therefore, as the mounting plate 7 moves and the mounting plate 7 gets close to the support block 16, the protective cloth 83 is rolled up under the action of the rebound force of the two second springs 811.
[0030] Reference Figure 4 and Figure 5The mounting plate 7 is provided with a mounting structure 9, which mainly consists of a mounting groove 91. The mounting groove 91 is formed on the mounting plate 7. A bolt 93 is threaded into the mounting plate 7. One end of the bolt 93 is rotatably connected to a limit block 94. The limit block 94 is slidably connected to the mounting groove 91. When a silicon rod is inserted into the mounting groove 91, the bolt 93 is rotated, which moves the limit block 94 downward to clamp and limit the silicon rod. A disc 95 is fixedly connected to the mounting plate 7. The disc 95 is threadedly connected to the bolt 93. Several circular grooves 98 are formed on the disc 95. One end of the bolt 93 is fixedly connected to a connecting block 96. A circular rod 97 is slidably inserted into the connecting block 96. After clamping, the circular rod 97 is slidably inserted into the corresponding circular groove. In section 98, bolt 93 can be limited. A third spring 99 is sleeved on the round rod 97. One end of the third spring 99 is fixedly connected to the round rod 97, and the other end of the third spring 99 is fixedly connected to the connecting block 96. After the round rod 97 is inserted into the round groove 98, the third spring 99 is in a stretched state. Therefore, the rebound force of the third spring 99 acts on the round rod 97, making the limiting more stable. Rubber blocks 92 are fixedly connected to both the mounting groove 91 and the limiting block 94. Several balls 910 are provided on the support block 16. The two rubber blocks 92 can prevent rigid contact from damaging the silicon rod, and the elasticity of the two rubber blocks 92 can adapt to the gap between the round grooves 98. The balls 910 can make the movement of the silicon rod smoother.
[0031] Working principle: The silicon rod is mounted on the mounting plate 7 and supported on the support block 16. The output end of the second motor 15 is connected to the rotating shaft 2 through a reducer and coupling. The model of the second motor 15 is Y2-160m1-8. Starting the second motor 15 drives the rotating shaft 2 to rotate. Under the action of the chain 14, the two rotating shafts 2 rotate synchronously, which in turn drives the cutting line 4 to move through the guide wheel 3. The cylinder 12 is started, and the piston rod of the cylinder 12 drives the slide rail 6 to rise until the cutting line 4 cuts the silicon rod. The nozzle 5 is connected to the external cutting fluid through a liquid pump. The cutting fluid can be sprayed through the nozzle 5 for cooling. The output end of the machine 11 is connected to the threaded rod 10 via a reducer and a coupling. The first motor 11 is a 17HS4401. Starting the first motor 11 drives the threaded rod 10 to rotate, which in turn moves the silicon rod via the mounting plate 7 to a suitable cutting position. The connecting cylinder 84 is installed on the mounting plate 7. The protective cloth 83 can block the threaded rod 10 to prevent debris from entering, and the two baffles 812 can further protect the gaps on both sides of the protective cloth 83, thus avoiding the possibility that debris may get stuck between the threads, increasing the friction of the screw during rotation, affecting the smooth rotation of the screw, and exacerbating the problem. Wear on the screw can shorten its service life. Sliding the two sliding rods 85 engages the locking rod 87 into the corresponding slot 88, allowing the connecting cylinder 84 to be mounted on the mounting plate 7 and thus limiting its position. When the locking rod 87 is engaged in the slot 88, the first spring 810 is in a stretched state. Therefore, the rebound force of the first spring 810 acts on the sliding rod 89, making the limiting more stable. When the protective cloth 83 is pulled open, the two second springs 811 are in a twisted state. Therefore, as the mounting plate 7 moves closer to the support block 16, the protective cloth 83 is subjected to the rebound force of the two second springs 811. Under the action of the mechanism, the silicon rod is wound up and inserted into the mounting groove 91. The bolt 93 is rotated, which drives the limiting block 94 to move downward to clamp and limit the silicon rod. After clamping, the sliding rod 97 is inserted into the corresponding circular groove 98 to limit the bolt 93. After the rod 97 is inserted into the circular groove 98, the third spring 99 is in a stretched state. Therefore, the rebound force of the third spring 99 acts on the rod 97, making the limiting more stable. The two rubber blocks 92 can prevent rigid contact from damaging the silicon rod, and the elasticity of the two rubber blocks 92 can adapt to the gap between the circular grooves 98. The ball bearing 910 can make the movement of the silicon rod smoother.
