Description

Technical Field

[0001] This invention relates to the field of tangent technology, specifically a multi-wire cutting method for eliminating wire jamming and breakage. Background Technology

[0002] Wire cutting is short for wire cutting, which refers to the cutting of conductive raw materials using wire tools such as metal wire or molybdenum wire. However, the diamond wire used for wire cutting needs to be cleaned and maintained in time after use. Therefore, when cleaning the diamond wire after use, the cutting of silicon material is suspended, and thus the silicon material cannot be continuously cut.

[0003] The prior art discloses Chinese patent application number CN202310671174.X, an automatic cutting device for solar cells. It discloses that the guide wheel continuously conveys the cutting line and the coating mechanism continuously sprays the cutting line at high speed, ensuring that the cutting fluid is evenly distributed on the surface of the cutting line. The cooperation between the lifting plate, the lifting mechanism and the control mechanism realizes the seamless connection of silicon ingot cutting and greatly reduces the waste of cutting fluid.

[0004] The aforementioned device can reduce coolant waste. However, existing devices require manual addition of coolant, which makes it difficult to accurately control the amount added. Furthermore, the use of coolant is also handled manually. This manual method of adding and removing coolant is not only inaccurate but also cumbersome and troublesome, increasing the complexity of the work process. Summary of the Invention

[0010] Furthermore, a rotating shaft connected to the chassis is provided on one side of the rotating drum. The rotating shaft and the chassis are rotatably connected by an electric slider. A rotating component is fixedly installed on the rotating shaft. An intermittent wheel is fixedly installed on the outside of the rotating drum.

[0011] Furthermore, an internal rod is fixedly installed in the middle of one side of the rotating drum, and pulleys are fixedly installed at one end of both the internal rod and the central rod, with a belt between the pulleys.

[0012] Furthermore, a round shaft is rotatably mounted on the middle of both sides of the chassis. An extrusion wheel is fixedly mounted on one end of the round shaft. A sprocket is fixedly mounted on both the end of the rotating shaft away from the rotating part and the middle of the round shaft. A chain is installed between the sprockets. A through groove is provided below the round shaft on the chassis. An extrusion plate is slidably mounted in the through groove. A spring is connected between the extrusion plate and the through groove.

[0013] Furthermore, one side of the upper surface of the extrusion plate is arc-shaped and contacts the extrusion wheel. A filter plate is fixedly installed in the lower part of the inner cavity of the machine box. A drainage plate is provided below the filter plate. A plug corresponding to the filter plate is provided on the drainage plate. The two sides of the drainage plate are beveled. A vertical rod fixedly connected to the drainage plate is provided on one side of the lower end surface of the extrusion plate. The vertical rod passes through and slides inside the filter plate.

[0014] Furthermore, a hollow frame is fixedly installed in the middle of the inner cavity of the chassis, and two corresponding bidirectional push plates are fixedly installed on both sides of the hollow frame. The two bidirectional push plates are jointly installed with two corresponding side plates. A threaded rod is rotatably installed on one side of the side plate, and two corresponding moving blocks are rotatably installed on the threaded rod. The moving blocks pass through and slide inside the side plate, and a limiting plate is fixedly installed at one end of the moving blocks.

[0015] Furthermore, a support plate is fixedly installed on both sides of the lower part of the hollow frame. Two corresponding adjustment rods are rotatably installed on the upper surface of the support plate by means of a thread. A contact plate is rotatably installed on the top of the adjustment rod, and a guide rod that passes through and slides with the support plate is fixedly installed on the lower end of the contact plate.

[0016] The beneficial effects of this invention are: 1. This invention uses a motor to drive two guide wheels to rotate, enabling the diamond wire to perform rotary cutting. Multiple sets of guide wheels are arranged between two fixed rings. After the diamond wire on any set of guide wheels is used up, the rotating drum rotates, causing the multiple sets of guide wheels on the fixed rings to be repositioned. This cleans the used diamond wire, and the repositioned diamond wire continues to cut the silicon material on the next set. Compared to existing wire cutting devices, this invention, by arranging multiple sets of diamond wires circumferentially along the axis of the rotating drum, allows for quick repositioning of the diamond wire, ensuring timely maintenance and cleaning after use without affecting the silicon material cutting operation. This also avoids wire breakage and jamming caused by continuous cutting of the diamond wire.

[0017] 2. This invention utilizes the telescopic sliding of an inner plate onto an outer sleeve, allowing the placement rack and guide wheel on the inner plate to adjust the cutting depth of the diamond wire, thereby achieving deep cutting of silicon material. Compared to existing devices, this invention can achieve deep cutting of silicon material by adjusting the position of the diamond wire when the silicon material cannot be cut further after reaching a certain depth, while simultaneously performing parallel cutting with the rotating diamond wire. The storage tank stores coolant, and the feeding tank automatically adds coolant to the spraying tank. Furthermore, when the silicon material is almost finished cutting, tap water is added to the feeding tank to dilute the silicon powder concentration. The remaining cutting coolant is then pumped out using a water pipe and recycled and replaced. The spray nozzle evenly sprays the coolant added to the spraying tank onto the surface of the diamond wire, thereby cooling down the high temperature generated during silicon material cutting. Simultaneously, the spraying of coolant also dilutes and cleans the silicon powder generated during cutting, further ensuring the quality of silicon material cutting.

[0018] 3. This invention uses a push-pull plate to drive the piston rod to compress the gas inside the cylinder. The compressed gas impacts the transmission pipe, subsequently causing the moving part in the control box to move downwards. At this point, multiple rubber plugs below the moving part release the blockage at the lower outlet of the storage tank, allowing the coolant in the storage tank to flow into the feeding tank through the outlet. This achieves automatic replenishment of coolant in the feeding tank. The vertical pipe is a threaded folded flexible hose. When the coolant in the spray box is low, the spray box moves upwards under the jacking of a spring. Simultaneously, the sponge block and control plug move upwards, controlling the flow. When the stopper moves upward, the blockage of the vertical pipe is removed. At this time, the coolant in the feeding tank flows into the spraying box through the vertical pipe to supply coolant to the nozzle. When a certain amount of coolant is added to the spraying box, the weight inside the spraying box increases. At this time, the force applied by the lifting plate to the spring increases, and the lifting plate drives the spraying box to move downward. When the spraying box moves downward, the sponge block and the control stopper move downward simultaneously. When the control stopper moves downward, it blocks the vertical pipe. At this time, the feeding tank stops adding coolant to the spraying box. Compared with the existing device, this invention can automatically add coolant according to the weight of the spraying box itself when cutting silicon material.

[0019] 4. In this invention, when multiple sets of diamond wires are interchanged, the electric slider is activated to drive the rotating shaft to rotate. When the rotating shaft rotates, it synchronously drives the rotating component to rotate. When the rotating component rotates, it drives the intermittent wheel to rotate through the circular block, thereby realizing the interchange between multiple sets of diamond wires. When the intermittent wheel rotates, it synchronously drives the internal rod to rotate. When the internal rod rotates, it synchronously drives the central rod to rotate through the pulley and belt. When the central rod rotates, it drives the cam to rotate, which can also realize the automatic replenishment of coolant.

[0020] 5. When the rotating shaft of this invention rotates, the sprocket and chain synchronously drive the round shaft to rotate. When the round shaft rotates, it drives the extrusion wheel to intermittently extrude the extrusion plate. After being extruded, the extrusion plate slides up and down in the through groove. When the extrusion plate slides up and down, it drives the drainage plate to slide up and down through the vertical rod. When the drainage plate moves down, the plug arranged on its upper part cancels the blockage of the filter plate. At this time, the coolant on the filter plate falls to the drainage plate and is discharged along the inclined side of the drainage plate. Compared with the existing device, this invention can automatically discharge the coolant after use when the diamond wire is changed, without the need for manual additional discharge treatment of coolant.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-10 As shown, a multi-wire cutting method for eliminating wire jamming and breakage is described. The multi-wire cutting method is implemented by a cutting device, which includes a housing 1. A rotating drum 20 is rotatably mounted on the upper part of the inner cavity of the housing 1. A fixing ring 21 is fixedly mounted on the outside of the rotating drum 20. An outer sleeve 211 is circumferentially mounted on the outer edge of the fixing ring 21. An inner plate 212 is slidably mounted in the middle of the outer sleeve 211. A placement frame 213 is fixedly mounted on one end of the inner plate 212. A wire guide wheel 214 is rotatably mounted inside the placement frame 213 by a motor. A diamond wire is mounted between two wire guide wheels 214. When the motor is turned on, the two wire guide wheels 214 rotate in coordination, which can drive the diamond wire to perform rotational cutting. Multiple sets of wire guide wheels 214 are provided between the two fixing rings 21. After the diamond wire on any set of wire guide wheels 214 is used up, the rotating drum 20 rotates, thereby changing the multiple sets of wire guide wheels 214 on the fixing ring 21, thereby cleaning the used diamond wire. At the same time, the diamond wire is moved to the set below to continue the cutting operation of silicon material.

[0025] Compared to existing wire cutting devices, this invention, by arranging multiple sets of diamond wires circumferentially along the axis of the rotating drum 20, enables rapid repositioning of the diamond wires, allowing for timely maintenance and cleaning after use without affecting the silicon material cutting operation. This avoids wire breakage and jamming caused by continuous cutting. The inner plate 212 slides and extends on the outer sleeve 211, allowing the placement frame 213 and guide wheel 214 on the inner plate 212 to adjust the cutting depth of the diamond wires, thereby achieving deep cutting of the silicon material. Compared to existing devices, this invention, while performing parallel cutting with rotating diamond wires, can adjust the position of the diamond wires when the silicon material cannot be cut further after reaching a certain depth, thus achieving... For deep cutting of silicon material, symmetrical fixing frames 24 are provided between two rotating drums 20. Symmetrical connecting rods 241 are provided in the middle of the two fixing frames 24. Mounting plates 242 are provided in the middle of the connecting rods 241. A storage box 25 is installed between the two mounting plates 242. The storage box 25 can store coolant. The feeding box 26 can automatically add coolant to the spraying box 27. The spray nozzle 274 can evenly spray the coolant added in the spraying box 27 onto the surface of the diamond wire, thereby cooling down the high temperature generated when the diamond wire cuts the silicon material. At the same time, the spraying of coolant can also dilute and clean the silicon powder generated during silicon material cutting, further ensuring the quality of silicon material cutting.

[0026] Below the storage box 25 is a feeding box 26 fixed to the mounting plate 242. Multiple vertical pipes 261 are located at the bottom of the feeding box 26, and a spray box 27 is installed between these vertical pipes 261. Multiple equally spaced spray nozzles 274 are installed on both sides of the spray box 27. An air cylinder 246 is fixedly installed on the upper part of a mounting bracket 24 on one side. A piston rod 247 is slidably installed inside the air cylinder 246. A central rod 243 is rotatably installed on the lower part of both mounting brackets 24, and a cam located below the air cylinder 246 is fixedly installed on the central rod 243. 244. A push-pull plate 245, which slides inside the piston rod 247, is rotatably mounted on one end of the cam 244. When the rotating drum 20 drives multiple sets of diamond wires to change positions, the rotating drum 20 synchronously drives the internal rod to rotate. The internal rod synchronously drives the central rod 243 to rotate through the pulley and belt. When the central rod 243 rotates, it synchronously drives the cam 244 to rotate. When the cam 244 rotates, it drives the piston rod 247 to perform compression operations in the air cylinder 246 through the push-pull plate 245, thereby facilitating the automatic replenishment of coolant.

[0027] A control box 251 is fixedly installed on the side of the storage tank 25 near the air cylinder 246. A transmission pipe 248 is installed between the control box 251 and the air cylinder 246. A strip-shaped groove is opened on the side of the control box 251 near the air cylinder 246, and a moving part 252 is installed in the strip-shaped groove. The upper part of the moving part 252 is shaped like a protrusion to block one end of the transmission pipe 248. A spring is connected between the lower part of the moving part 252 and the control box 251. Multiple liquid outlets are opened at the bottom of the storage tank 25, and multiple liquid outlets are provided at the bottom of the moving part 252. The blocked rubber plug 253 causes the push-pull plate 245 to drive the piston rod 247 to perform compression operations in the air cylinder 246. At this time, the gas in the air cylinder 246 is compressed and impacts the transmission pipe 248, which then impacts the moving part 252 in the control box 251 to move downward. At this time, the multiple rubber plugs 253 below the moving part 252 are no longer blocking the liquid outlet at the bottom of the storage tank 25. The coolant in the storage tank 25 flows to the feeding tank 26 through the liquid outlet, thereby realizing the automatic addition and replenishment of coolant in the feeding tank 26.

[0028] The spray box 27 has a sponge block 271 inside. Multiple control plugs 272 are fixedly installed on the upper surface of the sponge block 271. The control plugs 272 slide within the vertical tube 261. The feeding box 26 has T-shaped sides, with through slots in the middle of both sides. A lifting plate 273 is slidably installed within these slots. One end of the lifting plate 273 is fixedly connected to the spray box 27. Mounting blocks are fixedly installed on the lower parts of both sides of the feeding box 26. A spring is installed between the mounting blocks and the lifting plate 273. The vertical tube 261 is a threaded folded hose. When the coolant in the spray box 27 is low, the spray box 27 moves upward under the pressure of the spring. As the spray box 27 moves upward, the sponge block 271 and the control plugs 272 move upward simultaneously. When 72 moves upward, the blockage of the vertical pipe 261 is removed. At this time, the coolant in the feeding box 26 flows through the vertical pipe 261 into the spraying box 27 to supply coolant to the nozzle 274. When a certain amount of coolant is filled into the spraying box 27, the weight inside the spraying box 27 increases. At this time, the force applied by the lifting plate 273 to the spring increases. The lifting plate 273 then drives the spraying box 27 to move downward. When the spraying box 27 moves downward, the sponge block 271 and the control plug 272 move downward simultaneously. When the control plug 272 moves downward, it blocks the vertical pipe 261. At this time, the feeding box 26 stops filling the spraying box 27 with coolant. Compared with the existing device, the present invention can automatically add coolant according to the weight of the spraying box 27 itself when cutting silicon material.

[0029] A rotating ring 22 is mounted on the outer wall of the rotating cylinder 20 via an electric slider. Multiple circumferentially arranged arc-shaped grooves 221 are provided in the middle of the rotating ring 22. A drive column 222 is provided in the arc-shaped grooves 221. A strip groove is provided on the side of the outer sleeve 211 near the arc-shaped grooves 221. A push plate 223 connected to the inner plate 212 is provided in the strip groove. The end of the push plate 223 away from the inner plate 212 is fixedly connected to the drive column 222.

[0030] The electric slider opens and drives the rotating ring 22 to rotate. When the rotating ring 22 rotates, it drives the inner plate 212 to slide within the outer sleeve 211 through the drive column 222 and the push plate 223, thereby realizing the lifting and lowering control of the diamond wire.

[0031] A rotating shaft 23 connected to the housing 1 is provided on one side of the rotating drum 20. The rotating shaft 23 and the housing 1 are rotatably connected by an electric slider. A rotating component 231 is fixedly installed on the rotating shaft 23. An intermittent wheel 232 is fixedly installed on the outside of the rotating drum 20. A round block on one side of the rotating component 231 is placed into the intermittent wheel 232.

[0032] When multiple sets of diamond wires are swapped, the electric slider is activated, driving the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, it synchronously drives the rotating component 231 to rotate. When the rotating component 231 rotates, it drives the intermittent wheel 232 to rotate through the circular block, thereby realizing the swapping between multiple sets of diamond wires. When the intermittent wheel 232 rotates, it synchronously drives the internal rod to rotate. When the internal rod rotates, it synchronously drives the central rod 243 to rotate through the pulley and belt. When the central rod 243 rotates, it drives the cam 244 to rotate, which can also realize the automatic replenishment of coolant.

[0033] An internal rod is fixedly installed in the middle of one side of the rotating drum 20. A pulley is fixedly installed at one end of both the internal rod and the central rod 243, and a belt is provided between the pulleys.

[0034] Both sides of the housing 1 are rotatably mounted with a round shaft 11. One end of the round shaft 11 is fixedly mounted with an extrusion wheel 12. The end of the rotating shaft 23 away from the rotating part 231 and the middle of the round shaft 11 are both fixedly mounted with sprockets. A chain is installed between the sprockets. A through groove is provided below the round shaft 11 on the housing 1. An extrusion plate 13 is slidably mounted in the through groove. A spring is connected between the extrusion plate 13 and the through groove.

[0035] When the rotating shaft 23 rotates, the sprocket and chain synchronously drive the round shaft 11 to rotate. When the round shaft 11 rotates, it drives the extrusion wheel 12 to intermittently extrude the extrusion plate 13. After being extruded, the extrusion plate 13 slides up and down in the through groove. When the extrusion plate 13 slides up and down, it drives the drainage plate 15 to slide up and down through the vertical rod. When the drainage plate 15 moves down, the plug arranged on its upper part cancels the blockage of the filter plate 14. At this time, the coolant on the filter plate 14 falls to the drainage plate 15 and is discharged along the inclined side of the drainage plate 15. Compared with the existing device, the present invention can automatically discharge the coolant after use when the diamond wire is used for transposition, without the need for manual additional discharge treatment of coolant.

[0036] One side of the upper end face of the extrusion plate 13 is arc-shaped and contacts the extrusion wheel 12. A filter plate 14 is fixedly installed in the lower part of the inner cavity of the machine box 1. A drainage plate 15 is provided below the filter plate 14. A plug corresponding to the filter plate 14 is provided on the drainage plate 15. The two sides of the drainage plate 15 are beveled. A vertical rod is provided on one side of the lower end face of the extrusion plate 13 and is fixedly connected to the drainage plate 15. The vertical rod passes through and slides inside the filter plate 14.

[0037] A hollow frame 16 is fixedly installed in the middle of the inner cavity of the chassis 1. Two corresponding bidirectional push plates 165 are fixedly installed on both sides of the hollow frame 16. Two corresponding side plates 161 are installed on the two bidirectional push plates 165. A threaded rod 162 is rotatably installed on one side of the side plate 161. Two corresponding moving blocks 163 are rotatably installed on the threaded rod 162. The moving blocks 163 pass through and slide inside the side plate 161. A limiting plate 164 is fixedly installed at one end of the moving block 163. The multiple limiting plates 164 can limit and fix silicon materials of different specifications. The setting of the abutment plate 172 can stably support the bottom of the silicon material.

[0038] Both sides of the lower part of the hollow frame 16 are fixedly installed with a support plate 17. Two corresponding adjustment rods 171 are installed on the upper end of the support plate 17 by means of thread rotation. A contact plate 172 is rotatably installed on the top of the adjustment rod 171. A guide rod that passes through and slides with the support plate 17 is fixedly installed on the lower end of the contact plate 172.

[0039] In use, the motor drives the two guide rollers 214 to rotate, enabling the diamond wire to perform rotary cutting. Multiple sets of guide rollers 214 are arranged between the two fixed rings 21. After the diamond wire on any set of guide rollers 214 is used up, the rotating drum 20 rotates, causing the multiple sets of guide rollers 214 on the fixed rings 21 to be repositioned, thus cleaning the used diamond wire. Simultaneously, the repositioned diamond wire continues to cut the silicon material on the next set. Compared to existing wire cutting devices, this invention, by arranging multiple sets of diamond wires circumferentially along the axis of the rotating drum 20, can quickly cut the diamond wire. The diamond wire is repositioned to ensure timely maintenance and cleaning after use without affecting the silicon material cutting operation, thus avoiding wire breakage and jamming caused by continuous diamond wire cutting. The inner plate 212 slides on the outer sleeve 211, thereby allowing the placement frame 213 and guide wheel 214 on the inner plate 212 to adjust the cutting depth of the diamond wire, thereby achieving deep cutting of silicon material. Compared with existing devices, this invention can achieve deep cutting of silicon material by adjusting the position of the diamond wire when the silicon material cannot be cut to a certain depth during the parallel rotation of the diamond wire. The storage tank 25 stores coolant, and the feeding tank 26 automatically adds coolant to the spraying tank 27. The spray nozzle 274 evenly sprays the coolant from the spraying tank 27 onto the surface of the diamond wire, thus cooling the high temperature generated during silicon cutting. Simultaneously, the coolant spraying also dilutes and cleans the silicon powder generated during cutting, further ensuring the quality of silicon cutting. When the rotating drum 20 rotates and moves multiple sets of diamond wires to different positions, the internal rod rotates synchronously with the drum 20. The internal rod, through a pulley and belt, synchronously drives the central rod 243 to rotate. When the central rod 243 rotates... The cam 244 rotates synchronously. When the cam 244 rotates, it drives the piston rod 247 to perform compression work in the air cylinder 246 through the push-pull plate 245, which facilitates the automatic replenishment of coolant. The push-pull plate 245 drives the piston rod 247 to perform compression work in the air cylinder 246. At this time, the gas in the air cylinder 246 is compressed and impacts the conduction pipe 248, which then impacts the moving part 252 in the control box 251 to move downward. At this time, the multiple rubber plugs 253 below the moving part 252 unblock the liquid outlet at the bottom of the storage tank 25. The coolant in the storage tank 25 flows to the feeding tank 26 through the liquid outlet, thereby realizing the automatic addition and replenishment of coolant in the feeding tank 26. When the coolant in the spray box 27 is low, the spray box 27 moves upward under the lifting of the spring. As the spray box 27 moves upward, the sponge block 271 and the control plug 272 move upward simultaneously. When the control plug 272 moves upward, it releases the blockage on the vertical pipe 261. At this time, the coolant in the filling tank 26 flows into the spray box 27 through the vertical pipe 261, supplying coolant to the spray nozzle 274. After a certain amount of coolant has been added to the spray box 27, the weight of the spray box 27... The force applied to the spring by the lifting plate 273 increases, causing the lifting plate 273 to move the spray box 27 downward. As the spray box 27 moves downward, the sponge block 271 and the control plug 272 move downward simultaneously. When the control plug 272 moves downward, it blocks the vertical pipe 261. At this time, the feeding box 26 stops filling the spray box 27 with coolant. Compared with the existing device, the present invention can automatically add coolant according to the weight of the spray box 27 itself when cutting silicon material. When the rotating shaft 23 rotates, the sprocket and chain synchronously drive the round shaft 11 to rotate. When the round shaft 11 rotates, it drives the extrusion wheel 12 to intermittently extrude the extrusion plate 13. After being extruded, the extrusion plate 13 slides up and down in the through groove. When the extrusion plate 13 slides up and down, it drives the drainage plate 15 to slide up and down through the vertical rod. When the drainage plate 15 moves down, the plug arranged on its upper part cancels the blockage of the filter plate 14. At this time, the coolant on the filter plate 14 falls to the drainage plate 15 and is discharged along the inclined side of the drainage plate 15. Compared with the existing device, the present invention can automatically discharge the coolant after use when the diamond wire is used for transposition, without the need for manual additional discharge treatment of coolant.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
