Technical Field
[0001] The invention belongs to the technical field of single crystal silicon processing equipment, and in particular relates to a low-loss and high-precision single crystal silicon square rod loop squaring equipment. Background Art
[0002] Single crystal silicon square rod is a kind of high-purity silicon material, which is made by diamond wire cutting of single crystal silicon round rod. After processing, it can be made into various types of semiconductor devices such as transistors, diodes, MOSFET, etc. It can also be made into optical devices such as optical crystals and optical waveguides, providing technical support for optical communications, optical measurements, etc. As a basic material, single crystal silicon square rod has a wide range of applications in photovoltaic, semiconductor and other industries.
[0003] In the process of processing single crystal silicon round rods into single crystal silicon square rods, corresponding ring wire squaring equipment is needed. The ring wire squaring process can maximize the utilization of the material of the single crystal silicon round rod and reduce waste. Compared with traditional cutting methods, it has higher processing efficiency, can shorten the production cycle and reduce costs. However, in the actual use of existing ring wire squaring equipment, the length of the cutting line is mostly fixed, so that the cutting space formed by the cutting line is fixed. When processing some single crystal silicon round rods with smaller specifications, the fixed length cutting line design will make the length of the cutting line longer. Cutting at this time will easily cause the cutting line to loosen, thereby affecting the stability of the cutting line during cutting, increasing the loss of the single crystal silicon round rod and reducing its cutting accuracy.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] like Figures 1 to 10 As shown, the embodiment of the present invention provides a low-loss and high-precision single crystal silicon square rod ring line squaring device, including a horizontal plate 1, a lifting block 2 is fixedly installed in the middle of the rear end of the horizontal plate 1, and connecting rods 3 are movably sleeved on the left and right sides inside the horizontal plate 1, and the number of the connecting rods 3 is two. The front ends of the two connecting rods 3 are respectively fixedly installed with a first fixed block 4 and a second fixed block 5, and the rear sides of the top ends of the two connecting rods 3 are respectively hinged with inclined rods 6, and the number of the inclined rods 6 is two. The other ends of the two inclined rods 6 are respectively hinged with rectangular plates 7, and the inner surface of the front end of the rectangular plate 7 is movably sleeved with a limiting rod 8, and the bottom end of the limiting rod 8 is fixedly connected to the rear side of the middle part of the top end of the horizontal plate 1, and the top of the outer surface of the limiting rod 8 is fixedly sleeved with a stopper 9, and a driving motor 10 is fixedly installed on the front side of the middle part of the top end of the lifting block 2, and the other end of the output shaft of the driving motor 10 is fixedly sleeved with a driving screw 11, and the outer surface of the driving screw 11 is threadedly sleeved with the inner surface of the rear end of the rectangular plate 7, and the top of the outer surface of the driving screw 11 is movably sleeved with the inner surface of the rear end of the stopper 9.
[0032] When the driving motor 10 is started, the driving screw 11 will rotate. Since the driving screw 11 and the rectangular plate 7 are threadedly connected, the rectangular plate 7 will move along the outer surface of the limit rod 8 under the action of the driving screw 11. Since the upper and lower ends of the inclined rod 6 are respectively hinged to the rectangular plate 7 and the connecting rod 3, the top of the inclined rod 6 will move along with the movement of the rectangular plate 7, so that the bottom end of the inclined rod 6 produces a pulling force on the connecting rod 3, pulling the two connecting rods 3 to move toward each other along the inner surface of the cross plate 1 with the first fixed block 4 and the second fixed block 5 respectively. In this way, the length of the cutting line can be shortened by adjusting the spacing between the first fixed block 4 and the second fixed block 5, thereby preventing the cutting line from being too long when processing single crystal silicon rods with smaller specifications, making the cutting line more likely to loosen, thereby affecting the cutting accuracy.
[0033] Among them, the front end of the first fixed block 4 is fixedly sleeved with a retractable motor 12, and the other end of the output shaft of the retractable motor 12 is fixedly sleeved with a rotating shaft 13. The left end of the rotating shaft 13 passes through the first fixed block 4 and extends to the outside of the first fixed block 4 and is fixedly sleeved with a retractable wheel 14. The outer surface of the retractable wheel 14 is movably connected to the outer surface of the first fixed block 4, and the interior of the retractable wheel 14 is fixedly connected with a cutting line body 15.
[0034] When the retractable motor 12 is started, the rotating shaft 13 will drive the retractable wheel 14 to rotate. Since the cutting line body 15 is fixedly connected to the inside of the retractable wheel 14, the retractable operation of the cutting line body 15 can be achieved by rotating the retractable wheel 14.
[0035] Among them, a fixed shaft 16 is fixedly installed on the rear side of the middle of the left end of the first fixed block 4 and the second fixed block 5, and a guide wheel 17 is movably sleeved on the outer surface of the fixed shaft 16. There are two guide wheels 17, and the outer surfaces of the two guide wheels 17 are movably connected to the outer surfaces of the first fixed block 4 and the second fixed block 5 respectively, and the inner surfaces of the two guide wheels 17 are movably connected to the outer surface of the cutting line body 15.
[0036] The cooperation between the fixed shaft 16 and the guide wheel 17 serves to limit and guide the cutting wire body 15 .
[0037] Among them, an adjusting wheel 18 is movably connected to the front side of the middle part of the left end of the second fixed block 5, the inner surface of the adjusting wheel 18 is fixedly connected to the outer surface of the cutting line body 15, and a round rod 19 is fixedly sleeved inside the adjusting wheel 18. The right end of the round rod 19 penetrates the second fixed block 5 and extends to the right side of the outer surface of the second fixed block 5. The outer surface of the round rod 19 is movably sleeved with the inner surface of the second fixed block 5, and a gear 20 is fixedly sleeved in the middle part of the outer surface of the round rod 19, and the outer surface of the gear 20 is movably sleeved with the inner surface of the second fixed block 5.
[0038] When the gear 20 rotates along the inner surface of the second fixed block 5, since the gear 20 and the adjusting wheel 18 are fixedly sleeved on the outer surface of the round rod 19, the round rod 19 will rotate with the adjusting wheel 18 under the action of the gear 20, so that the adjusting wheel 18 rotates with one end of the cutting line body 15, and then the tension of the cutting line body 15 is adjusted, thereby improving the cutting stability.
[0039] Among them, a power motor 21 is fixedly installed on the right side of the bottom end inside the second fixed block 5, and a power screw 22 is fixedly sleeved on the other end of the output shaft of the power motor 21. A tooth plate 23 is threadedly sleeved on the outer surface of the power screw 22. The outer surface of the tooth plate 23 is movably sleeved on the inner surface of the second fixed block 5, and the left side of the outer surface of the tooth plate 23 is meshedly connected with the outer surface of the gear 20.
[0040] When the power motor 21 is started, the power screw 22 will rotate. Since the outer surface of the power screw 22 and the inner surface of the tooth plate 23 are threadedly connected, the tooth plate 23 will move along the inner surface of the second fixed block 5 under the action of the power screw 22, thereby causing the gear 20 meshing with the tooth plate 23 to rotate.
[0041] Among them, a back plate 24 is movably sleeved on the rear side of the outer surface of the lifting block 2, a base 25 is fixedly installed on the bottom of the front end of the back plate 24, a first motor 26 is fixedly sleeved inside the bottom of the back plate 24, and a first threaded rod 27 is fixedly sleeved on the other end of the output shaft of the first motor 26. The top end of the first threaded rod 27 penetrates the back plate 24 and extends to the top of the back plate 24. The outer surface of the first threaded rod 27 is threadedly sleeved with the inner surface of the lifting block 2.
[0042] When the first motor 26 is started, the first threaded rod 27 will rotate. Since the outer surface of the first threaded rod 27 and the inner surface of the lifting block 2 are threadedly connected, the lifting block 2 will move along the inner surface of the back plate 24 with the cross plate 1 under the action of the first threaded rod 27, and the back plate 24 and the base 25 play a supporting and fixing role.
[0043] Among them, the left side of the top of the base 25 is movably connected to a placing table 28, and the inside of the placing table 28 is movably sleeved with a double-threaded rod 29. The left and right sides of the outer surface of the double-threaded rod 29 are respectively threadedly sleeved with clamping blocks 30. There are two clamping blocks 30, and the outer surfaces of the two clamping blocks 30 are respectively movably sleeved with the inner surface of the placing table 28.
[0044] Since the inner surface of the clamp block 30 and the outer surface of the double-threaded rod 29 are threadedly connected, when the double-threaded rod 29 is rotated, the two clamp blocks 30 will move toward each other along the inner surface of the placement table 28 under the action of the double-threaded rod 29, thereby clamping and fixing the single crystal silicon round rod.
[0045] Among them, a round shaft 31 is fixedly installed in the middle of the bottom end of the placement table 28, the outer surface of the round shaft 31 is movably connected to the inner surface of the base 25, the bottom of the outer surface of the round shaft 31 is movably connected to a movable block 32, the outer surface of the movable block 32 is movably connected to the left side of the inner surface of the base 25, and the bottom end of the round shaft 31 is fixedly connected to a round wheel 33, and the top of the round wheel 33 is movably connected to the top of the inner surface of the movable block 32.
[0046] When the circular wheel 33 rotates, it will rotate with the placement table 28 through the circular shaft 31, and when the movable block 32 moves along the inner surface of the horizontal plate 1, it will move with the placement table 28 through the circular shaft 31.
[0047] Among them, a connecting rod 34 is hinged at the top of the middle part of the front end of the round wheel 33, and a rectangular block 35 is hinged at the other end of the connecting rod 34. The bottom of the outer surface of the rectangular block 35 and the bottom of the inner surface of the movable block 32 are movably connected. A pneumatic cylinder 36 is fixedly installed at the right end of the rectangular block 35, and the right end of the pneumatic cylinder 36 is fixedly connected to the right inner wall of the movable block 32.
[0048] When the pneumatic cylinder 36 is started, the rectangular block 35 will move with one end of the connecting rod 34, so that the other end of the connecting rod 34 will generate a pulling force on the round wheel 33, pulling the round wheel 33 to rotate around the circular shaft 31 as the axis. When the rectangular block 35 moves to the left inner wall of the movable block 32, the round wheel 33 can be rotated ninety degrees.
[0049] Among them, a second motor 37 is fixedly sleeved on the bottom of the left end of the base 25, and a second threaded rod 38 is fixedly sleeved on the other end of the output shaft of the second motor 37. The right end of the second threaded rod 38 passes through the base 25 and extends to the inside of the base 25. The left side of the outer surface of the second threaded rod 38 is threadedly sleeved with the inner surface of the bottom end of the movable block 32.
[0050] When the second motor 37 is started, the second threaded rod 38 will rotate, so that the movable block 32 moves along the inner surface of the horizontal plate 1 under the action of the second threaded rod 38, so that the placement table 28 moves together through the movable block 32 and the circular shaft 31.
[0051] Working principle and usage process:
[0052] When in use, the operator first starts the driving motor 10 according to the specifications of the single crystal silicon round rod, so that the driving screw 11 rotates, so that the rectangular plate 7 threadedly sleeved on the outer surface of the driving screw 11 moves along the outer surface of the limit rod 8 with the top of the inclined rod 6, so that the bottom end of the inclined rod 6 generates a pulling force on the connecting rod 3, pulling the two connecting rods 3 to move toward each other along the inner surface of the cross plate 1 with the connecting rod 3 and the first fixed block 4 respectively, until the spacing between the first fixed block 4 and the second fixed block 5 matches the specifications of the single crystal silicon round rod. Then the operator starts the retracting and discharging motor 12, so that the rotating shaft 13 drives the retracting and releasing wheel 14 to rotate, thereby rewinding the cutting line body 15 and straightening the cutting line body 15. With the mutual cooperation of various mechanisms, the length of the cutting line body 15 is adjusted, thereby preventing the cutting line body 15 from being too long when processing single crystal silicon round rods with smaller specifications, making the cutting line body 15 more likely to relax.
[0053] Then the operator starts the power motor 21 to rotate the power screw 22. At this time, the tooth plate 23 threadedly sleeved on the outer surface of the power screw 22 will move along the inner surface of the second fixed block 5. As the tooth plate 23 moves, the gear 20 meshing with the tooth plate 23 will rotate with the round rod 19, so that the adjusting wheel 18 rotates with one end of the cutting line body 15 through the round rod 19, thereby adjusting the tension of the cutting line body 15 to improve the stability of the cutting line body 15 during cutting.
[0054] Subsequently, the operator places the monocrystalline silicon round rod on the top of the placement table 28, and then rotates the double-threaded rod 29, so that the two clamping blocks 30 move toward each other and clamp the monocrystalline silicon round rod. Then, the operator starts the second motor 37 to rotate the second threaded rod 38, so that the movable block 32 moves with the placement table 28 through the round shaft 31 under the action of the second threaded rod 38 until the cutting position of the monocrystalline silicon round rod is aligned with the cutting line body 15. Then, the operator can start the first motor 26 to rotate the first threaded rod 27, so that the lifting block 2 threadedly sleeved on the outer surface of the first threaded rod 27 moves downward with the cross plate 1, and then passes through the cutting line body. 15 performs the cutting operation. After the two longitudinal surfaces of the monocrystalline silicon round rod are cut, the operator resets the cutting line body 15 and then starts the pneumatic cylinder 36, so that the rectangular block 35 moves with one end of the connecting rod 34, so that the other end of the connecting rod 34 generates a pulling force on the round wheel 33, pulling the round wheel 33 through the round shaft 31 to rotate with the placement table 28 until the round wheel 33 rotates ninety degrees with the placement table 28, and then starts the first motor 26 again to complete the cutting of the remaining two surfaces of the monocrystalline silicon round rod, so that the cutting position of the monocrystalline silicon round rod can be adjusted, thereby reducing the time consumed in the cutting process and improving the cutting rate of the monocrystalline silicon square rod ring line squaring equipment.
