Description

Technical Field

[0001] This invention relates to the field of crystal cutting technology, and more specifically, to a crystal multi-wire cutting device. Background Technology

[0002] A multi-wire crystal cutting device is a specialized piece of equipment for slicing crystal materials. It uses multiple metal wires to move synchronously at high speed, in conjunction with grinding fluid, to continuously grind and cut the crystal workpiece. It can process rod-shaped and block-shaped crystals into thin slices with uniform thickness. It features high cutting accuracy, low material loss, and high processing efficiency. It is mainly used for slicing various crystal materials such as silicon, sapphire, and quartz.

[0003] During the multi-wire cutting process of crystal materials, the cutting wires are in a high-speed cyclic operation state for a long time, continuously bearing large tensile stress and alternating loads. Under long-term continuous operation, the cutting wires will gradually undergo plastic elongation, resulting in a decrease in tension and insufficient tension. This leads to a reduction in the running stability of the cutting wires, causing problems such as shaking, loosening, and even cutting path deviation. Ultimately, this results in uneven kerf width and positional deviation, affecting the thickness consistency and cutting accuracy of crystal slices, and reducing the yield of finished products. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a crystal multi-wire cutting device to solve the problem that the plastic elongation of the cutting wire leads to a decrease in tension and insufficient tension, which reduces the stability of the cutting wire operation.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A multi-wire crystal cutting device includes a cutting equipment housing and a crystal displacement stage. The crystal displacement stage is installed inside the cutting equipment housing and is used to carry and move the crystal. It also includes a tensioning mechanism located inside the cutting equipment housing. The tensioning mechanism includes two wire wheel shafts rotatably connected inside the cutting equipment housing. Multiple cutting wires are wound around the surface of the wire wheel shafts. Two heavy-duty blocks are disposed inside the cutting equipment housing. Suspension connecting plates are fixedly connected to both ends of the upper surfaces of the two heavy-duty blocks. A heavy-duty shaft is rotatably connected between the two suspension connecting plates on the same heavy-duty block. The two heavy-duty shafts are drive-connected to the multiple cutting wires.

[0007] Furthermore, each end of the heavy-duty block is fixedly connected to a movable connecting block, and the surfaces of the four movable connecting blocks are slidably connected to guide rails, and the four guide rails are fixedly connected to the interior of the cutting equipment housing.

[0008] Furthermore, it also includes an oscillation elimination mechanism, which is disposed inside the housing of the cutting equipment. The oscillation elimination mechanism includes a silicone oil tank fixedly connected inside the housing of the cutting equipment. The silicone oil tank is filled with silicone oil. A pressure shaft is rotatably connected inside the silicone oil tank. Multiple cutting lines are drivenly connected to the pressure shaft and pass through the silicone oil tank.

[0009] Furthermore, the silicone oil tank is provided with a connecting strip inside, and multiple cleaning rings are fixedly inserted inside the connecting strip. The multiple cutting lines are respectively inserted into the interior of the multiple cleaning rings.

[0010] Furthermore, multiple tension springs are fixedly connected to both the upper and lower surfaces of the connecting strip, and the ends of the two sets of tension springs that are far apart from each other are fixedly connected to the upper and lower surfaces inside the silicone oil tank, respectively.

[0011] Furthermore, a first silicone oil delivery pipe is connected to the left surface of the silicone oil tank, a liquid pump is fixedly connected to the upper surface of the silicone oil tank, a second silicone oil delivery pipe is connected to the lower inlet of the liquid pump, and a heat sink is connected between the first silicone oil delivery pipe and the second silicone oil delivery pipe.

[0012] Furthermore, multiple heat-conducting copper rods are fixedly inserted inside the heat sink box.

[0013] Furthermore, the outlet of the liquid pump is fixedly inserted into the interior of the silicone oil tank. The outlet of the liquid pump is connected to a silicone oil delivery hose, and the surface of the silicone oil delivery hose is connected to a silicone oil output pipe. A motor is fixedly connected inside the casing of the cutting equipment. A rotating disk is fixedly connected to the output shaft of the motor. An active lifting rod is fixedly connected to the surface of the rotating disk. A passive lifting rod is fixedly connected to the upper surface of the silicone oil output pipe. A rotating support plate is fixedly connected to the bottom surface of the silicone oil tank. The silicone oil output pipe is rotatably connected to the rotating support plate. Elastic rubber strips are fixedly connected to the front and rear inner walls of the silicone oil tank. The ends of the two elastic rubber strips that are close to each other are fixedly connected to the surface of the silicone oil output pipe.

[0014] Furthermore, a plurality of receiving boxes are fixedly connected to the upper surface of the silicone oil tank, and a lifting plate is slidably inserted inside each of the plurality of receiving boxes. A card box is fixedly connected to the upper surface of the lifting plate, and the inner wall width of the card box is the same as the distance between two adjacent cutting lines and the positions are corresponding. A first spring is fixedly connected to the lower surface of the lifting plate.

[0015] Furthermore, brackets are fixedly connected to both sides of the upper end of the lifting plate, clamps are inserted into both ends of the card box, a second spring is fixedly connected between the clamp and the longitudinal arm end of the bracket, and two support columns are fixedly connected to the sides of the two clamps that are far apart from each other, and the support columns are inserted into the interior of the longitudinal arm end of the bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) If the cutting line becomes elongated and loose due to long-term cutting, the heavy block pulls the heavy shaft downward by its own weight, so that the heavy shaft always maintains a transmission connection with the cutting line, maintains the tension of the cutting line, prevents the cutting line from running unstably and the cutting path from deviating due to insufficient tension, and ensures the consistency of the crystal slice thickness.

[0017] (2) In this scheme, the cutting line naturally enters the silicone oil tank when it is in high-speed cyclic motion. With the help of the pressure shaft, the cutting line is concave downward and completely immersed in the silicone oil. The buffering effect of the viscous silicone oil is used to counteract the vibration caused by the high-speed movement of the cutting line, avoid the vibration causing the cutting path to deviate, and improve the cutting accuracy.

[0018] (3) This solution uses a liquid pump to realize the circulation input and output of silicone oil in the silicone oil tank, avoiding the temperature carried by the cutting wire from causing the local silicone oil to become thinner. Furthermore, when the silicone oil flows through the heat dissipation box, the heat-conducting copper rod transfers the heat of the silicone oil to the outside of the box for heat dissipation, reducing the overall temperature of the silicone oil and ensuring the buffering performance of the silicone oil.

[0019] (4) In this scheme, the crystal contacts and squeezes the inclined surface of the clamping block inside the card box, causing the clamping block to move out of the card box and the second spring to compress. The compressed second spring provides a pushing force to the clamping block to clamp the crystal, which plays a supporting role for the crystal that is about to be cut through, reducing the probability of crystal chipping. Even if the crystal chipped, it can prevent the crystal from falling and reduce economic losses. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-3 A multi-wire crystal cutting device includes a cutting equipment housing 1 and a crystal displacement stage 2. The crystal displacement stage 2 is installed inside the cutting equipment housing 1 and is used to carry and move the crystal. It also includes a tensioning mechanism located inside the cutting equipment housing 1. The tensioning mechanism includes two wire wheel shafts 302 rotatably connected inside the cutting equipment housing 1. Multiple cutting wires 301 are wound around the surface of the wire wheel shafts 302. Two heavy-duty blocks 304 are disposed inside the cutting equipment housing 1. Suspension connecting plates 307 are fixedly connected to both ends of the upper surfaces of the two heavy-duty blocks 304. A heavy-duty shaft 306 is rotatably connected between the two suspension connecting plates 307 on the same heavy-duty block 304. The two heavy-duty shafts 306 are drively connected to the multiple cutting wires 301. Movable connecting blocks 305 are fixedly connected to both ends of the heavy-duty blocks 304. Guide rails 303 are slidably connected to the surfaces of the four movable connecting blocks 305. The four guide rails 303 are fixedly connected to the interior of the cutting equipment housing 1.

[0024] By adopting the above technical solution, when cutting the crystal, the crystal is installed on the crystal displacement stage 2, and the power component inside the cutting equipment housing 1 drives the two threaded shafts 302 to rotate at high speed, thereby driving multiple cutting lines 301 to circulate at high speed. Then, the crystal displacement stage 2 drives the crystal to gradually move downwards until it contacts the cutting lines 301 that are circulating at high speed, so that the crystal can be cut. This is a common method in the prior art, and will not be described in detail here.

[0025] When the cutting wire 301 stretches and relaxes during long-term crystal cutting, the heavy pressure block 304, due to its large weight, pulls the heavy pressure shaft 306 downwards by its own gravity. This ensures that the heavy pressure shaft 306 remains connected to the cutting wire 301 even when the cutting wire 301 stretches and relaxes. This prevents the cutting wire 301 from becoming less stable and causing the cutting path to deviate when the tension of the cutting wire 301 decreases or becomes insufficient. This improves the thickness consistency and cutting accuracy of the crystal slices, thereby increasing the yield rate of the finished product.

[0026] like Figures 4-6 As shown, it also includes an oscillation elimination mechanism, which is disposed inside the housing 1 of the cutting equipment. The oscillation elimination mechanism includes a silicone oil tank 401 fixedly connected inside the housing 1 of the cutting equipment. The silicone oil tank 401 is filled with silicone oil. A pressure shaft 402 is rotatably connected inside the silicone oil tank 401. Multiple cutting lines 301 are drivenly connected to the pressure shaft 402, and multiple cutting lines 301 pass through the silicone oil tank 401.

[0027] The silicone oil tank 401 has a connecting strip 410 inside, and multiple cleaning rings 412 are fixedly inserted inside the connecting strip 410. Multiple cutting lines 301 are respectively inserted into the interior of the multiple cleaning rings 412. Multiple tension springs 411 are fixedly connected to the upper and lower surfaces of the connecting strip 410. The ends of the two sets of tension springs 411 that are far apart from each other are fixedly connected to the upper and lower surfaces inside the silicone oil tank 401, respectively.

[0028] The left surface of the silicone oil tank 401 is connected to a first silicone oil delivery pipe 403, the upper surface of the silicone oil tank 401 is fixedly connected to a liquid pump 406, the lower inlet of the liquid pump 406 is connected to a second silicone oil delivery pipe 405, a heat sink 404 is connected between the first silicone oil delivery pipe 403 and the second silicone oil delivery pipe 405, and a plurality of heat-conducting copper rods 408 are fixedly inserted inside the heat sink 404.

[0029] The liquid pump 406 has its outlet fixedly inserted into the interior of the silicone oil tank 401. The outlet of the liquid pump 406 is connected to a silicone oil delivery hose 413, and the surface of the silicone oil delivery hose 413 is connected to a silicone oil output pipe 407. A motor 415 is fixedly connected inside the outer shell 1 of the cutting equipment. A rotating disk 416 is fixedly connected to the output shaft of the motor 415. An active lifting rod 417 is fixedly connected to the surface of the rotating disk 416. A passive lifting rod 418 is fixedly connected to the upper surface of the silicone oil output pipe 407. A rotating support plate 414 is fixedly connected to the bottom surface of the silicone oil tank 401. The silicone oil output pipe 407 is rotatably connected to the rotating support plate 414. Elastic rubber strips 409 are fixedly connected to the front and rear inner walls of the silicone oil tank 401. The ends of the two elastic rubber strips 409 that are close to each other are fixedly connected to the surface of the silicone oil output pipe 407.

[0030] By adopting the above technical solution, during the high-speed cyclic movement of the cutting wire 301, the cutting wire 301 enters the silicone oil tank 401, and through the cooperation of the downward pressure shaft 402, the cutting wire 301 is recessed downward, immersing itself in the silicone oil. During the high-speed cyclic movement of the cutting wire 301, in the event of vibration, the viscous silicone oil can act as a buffer, reducing the vibration of the cutting wire 301 and preventing the cutting path deviation caused by vibration during the high-speed cyclic movement of the cutting wire 301. This improves the thickness consistency and cutting accuracy of the crystal slices, and further increases the finished product qualification rate.

[0031] When the cutting wire 301 is removed from the silicone oil, the cleaning ring 412 wraps around the cutting wire 301, thus scraping off the silicone oil on the surface of the cutting wire 301 and reducing the consumption of silicone oil. The tension spring 411 can automatically adjust the connecting strip 410 and the cleaning ring 412 according to the angle of the cutting wire 301, reducing the risk of the cleaning ring 412 being cut by the cutting wire 301 due to misalignment of the angle.

[0032] When the cutting wire 301 enters the silicone oil, the temperature carried by the surface of the cutting wire 301 will heat the silicone oil in the contact area, making the silicone oil thinner and affecting the buffering effect provided by the silicone oil. Therefore, the silicone oil inside the silicone oil tank 401 can be circulated and output by the liquid pump 406, so as to mix and flow the silicone oil inside the silicone oil tank 401, reduce temperature accumulation, improve the buffering effect of the silicone oil, and further improve the finished product qualification rate. When silicone oil flows out of silicone oil output pipe 407, motor 415 can drive rotating disk 416 and active lifting rod 417 to rotate, so that active lifting rod 417 repeatedly contacts and pushes passive lifting rod 418. Then, the silicone oil output pipe 407 returns to the center state through the cooperation of two elastic rubber strips 409. By repeating this process, the silicone oil output pipe 407 can be oscillating back and forth, which can improve the mixing effect of silicone oil, reduce temperature accumulation, improve the buffering effect of silicone oil, and further improve the finished product qualification rate. In addition, when silicone oil flows through heat sink 404, heat-conducting copper rod 408 transfers the heat in silicone oil to the outside of heat sink 404 for heat dissipation treatment, thereby reducing the temperature of silicone oil.

[0033] like Figure 7 and Figure 8 As shown, a plurality of receiving boxes 501 are fixedly connected to the upper surface of the silicone oil tank 401. A lifting plate 502 is slidably inserted inside each of the plurality of receiving boxes 501. A card box 505 is fixedly connected to the upper surface of the lifting plate 502. The inner wall width of the card box 505 is the same as the distance between two adjacent cutting lines 301 and the positions are corresponding. A first spring 503 is fixedly connected to the lower surface of the lifting plate 502. The first spring 503 can provide resistance so that the crystal can be squeezed between the two clamping blocks 506 without affecting the downward movement of the crystal. A bracket 504 is fixedly connected to both sides of the upper end of the lifting plate 502. A clamping block 506 is inserted into both ends of the card box 505. A second spring 508 is fixedly connected between the clamping block 506 and the longitudinal arm end of the bracket 504. Two support columns 507 are fixedly connected to the sides of the two clamping blocks 506 that are far apart from each other. The support columns 507 are inserted into the interior of the longitudinal arm end of the bracket 504.

[0034] By adopting the above technical solution, when the crystal displacement stage 2 moves the crystal downward, the cutting line 301 can cut the crystal. The cut part passes through the cutting line 301 and is inserted into the card box 505. As the crystal continues to move downward, the crystal contacts and squeezes the inclined surface of the clamping block 506, causing the clamping block 506 to move out of the card box 505. At this time, the second spring 508 is in a compressed state. The second spring 508 can provide a pushing force to the clamping block 506 to clamp the crystal. It can play a supporting role when the crystal is about to be cut through, reducing the probability of the crystal chipping. Even if chipping occurs, it will not fall, reducing economic losses during the cutting process.

[0035] Instructions for use: First, mount the crystal to be cut on the crystal displacement stage 2; Subsequently, the power unit inside the casing 1 of the cutting equipment is activated, driving the two wire wheel shafts 302 to rotate at high speed, which in turn drives the multiple cutting wires 301 to circulate at high speed. Next, the crystal is slowly moved downward by the crystal displacement stage 2 until it comes into contact with the high-speed circulating cutting line 301, and the crystal cutting operation begins. During the cutting process, if the cutting line 301 becomes elongated and slack due to prolonged cutting, the heavy pressure block 304 pulls the heavy pressure shaft 306 downwards by its own weight, so that the heavy pressure shaft 306 always maintains a transmission connection with the cutting line 301, maintains the tension of the cutting line 301, prevents the cutting line 301 from running unsteadily and the cutting path from deviating due to insufficient tension, and ensures the consistency of the crystal slice thickness. When the cutting line 301 is in high-speed cyclic motion, it naturally enters the silicone oil tank 401. With the help of the pressure shaft 402, the cutting line 301 is concave downward and completely immersed in the silicone oil. The buffering effect of the viscous silicone oil is used to counteract the vibration generated by the high-speed motion of the cutting line 301, avoid the vibration from causing the cutting path to deviate, and improve the cutting accuracy. At the same time, the liquid pump 406 is started to realize the circulation input and output of silicone oil in the silicone oil tank 401, so as to prevent the local silicone oil from thinning due to the temperature carried by the cutting wire 301. When silicone oil flows out, the starting motor 415 drives the rotating disk 416 and the active lifting rod 417 to rotate. The active lifting rod 417 repeatedly pushes the passive lifting rod 418, which, together with the elastic rubber strip 409, makes the silicone oil output pipe 407 swing back and forth, improving the silicone oil mixing effect and reducing temperature accumulation. When the silicone oil flows through the heat sink 404, the thermally conductive copper rod 408 transfers the heat of the silicone oil to the outside of the box for heat dissipation, reducing the overall temperature of the silicone oil and ensuring the buffering performance of the silicone oil. The crystal displacement stage 2 continuously drives the crystal to move downwards, and the cut crystal part passes through the cutting line 301 and is inserted into the card box 505; Subsequently, the crystal contacts and is pressed against the inclined surface of the clamping block 506 inside the cartridge 505, causing the clamping block 506 to move outward from the cartridge 505 and the second spring 508 to be compressed. The compressed second spring 508 provides a pushing force to the clamping block 506 to clamp the crystal, which plays a supporting role for the crystal that is about to be cut through, reducing the probability of crystal chipping. Even if chipping occurs, it can prevent the crystal from falling and reduce economic losses.
