[0001] This invention relates to the field of monocrystalline silicon processing technology, and in particular to a feeding device, a crystal rod grinding system, and a method for a crystal rod grinding machine. Background Technology

[0002] After the crystal rod is drawn, because the crystal rod has an irregular cylindrical shape, the outer circumference of the crystal rod needs to be rolled and ground into a regular cylinder of a certain diameter to meet the requirements of subsequent slicing.

[0003] When processing crystal ingots, a tumbling mill is primarily used. Currently, loading and unloading 4-inch, 5-inch, 6-inch, and 8-inch tumbling mills mainly relies on manual labor—lifting the ingots by hand and then securing them to the mill. However, as the diameter and length of the crystal ingots increase, their weight also increases significantly. This not only greatly increases the workload for loading personnel but also significantly increases the risk of collision damage during loading and unloading. Furthermore, due to the substantial increase in weight, the ingots are easily dropped by personnel, posing a significant safety hazard. Summary of the Invention

Detailed Implementation

[0025] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0026] This invention provides a feeding device and a crystal rod grinding system for a crystal rod grinding mill. See [link to relevant documentation]. Figure 1-8 .

[0027] This invention provides a feeding device 90 for a crystal rod grinding machine, comprising: a fixing mechanism 10, a rotating mechanism 20, a lifting mechanism 30, a translating mechanism 40, and a clamping mechanism 50; the bottom end of the fixing mechanism 10 is fixed to one end of the crystal rod grinding machine 60, and the other end is rotatably connected to the bottom end of the rotating mechanism 20; the upper end of the rotating mechanism 20 is fixedly connected to the bottom end of the lifting mechanism 30; the upper end of the lifting mechanism 30 is movably connected to one end of the translating mechanism 40, and the translating mechanism 40 can move up and down vertically on the lifting mechanism 30; the upper end of the clamping mechanism 50 is movably fixed on the translating mechanism 40 and can move horizontally on the translating mechanism 40; the lower end of the clamping mechanism 50 is used to clamp the crystal rod to be ground.

[0028] In this embodiment, by setting up a feeding device 90 for the crystal rod grinding machine, operators no longer need to manually lift the crystal rods to feed them onto the grinding machine. This not only greatly reduces the labor intensity of workers but also prevents crystal rods from falling and injuring the feeding personnel, reducing safety hazards during the feeding process. Furthermore, the rotating mechanism 20, lifting mechanism 30, and translation mechanism 40 in the feeding device are precisely controlled by the drive component 31 or a manual knob, enabling accurate handling of the crystal rods and significantly reducing collision damage and losses during transport.

[0029] In addition, the clamping mechanism 50 provided by this solution can accommodate the clamping of crystal rods of more sizes, thus enabling it to adapt to the feeding operation of crystal rods of more sizes in the grinding mill, with a wider range of applications and higher applicability.

[0030] In one embodiment, the fixing mechanism 10 is a cylindrical structure with its bottom end fixed to the ground, its interior being a hollow cavity, and its upper end being an opening with a recessed platform at the opening.

[0031] The rotating mechanism 20 mainly includes: a worm gear 21, a worm 22, a pressure bearing 23, and a first drive knob 24. The worm gear 21 is located inside the fixed mechanism 10, and its upper end is a circular structure that extends out from the opening of the fixed mechanism 10 and is movably connected to the fixed mechanism 10. The worm 22 is meshed with the worm gear 21, and the other end of the worm 22 extends out from the side of the fixed mechanism 10 and is fixedly connected to the first drive knob 24 located on the outer surface of the fixed mechanism 10. The pressure bearing 23 is a ring structure with a large upper circular surface and a small lower circular surface. The pressure bearing 23 is located on a recessed platform at the opening of the fixed mechanism 10. The rod-shaped part of the worm gear 21 passes through the center of the ring of the pressure bearing 23 so that the upper circular surface of the pressure bearing 23 contacts the lower surface of the upper circular surface of the worm gear 21, and the lower circular surface of the pressure bearing 23 contacts the surface of the recessed platform.

[0032] In this embodiment, the main body of the worm gear 21 is a columnar structure located inside the hollow cavity of the fixing mechanism 10. A rack 42 structure is provided on the surface of the columnar structure. The upper end of the columnar structure is a circular structure, movably connected to the opening side of the fixing mechanism 10. A pressure bearing 23 is provided between the lower surface of the upper end face of the worm gear 21 and the recess at the upper opening of the fixing mechanism 10. The worm 22 and the worm gear 21 are meshed. Thus, when the first drive knob 24, which is fixedly connected to the worm 22, is rotated, the worm 22 can rotate, and the rotation of the worm 22 can drive the rotation of the worm gear 21. The rotation of the worm gear 21 can drive the lifting mechanism 30, which is connected to the rotating mechanism 20, to rotate, thereby rotating the clamping mechanism 50 and rotating the crystal rod held by the clamping mechanism 50 to the desired transport direction.

[0033] In one embodiment, the rotating mechanism 20 can rotate 360°. Thus, when there are multiple tumbling mills on site, the feeding device 90 of the crystal rod tumbling mill can be set between two adjacent tumbling mills, so that the feeding device 90 of one crystal rod tumbling mill can supply two tumbling mills for feeding operations, which greatly reduces the feeding cost.

[0034] In one embodiment, the upper surface of the upper circular surface of the worm gear 21 may be provided with a rectangular groove; the lifting mechanism 30 may include: a drive assembly 31, a lead screw assembly 32 and a first connecting member 33; one end of the lead screw assembly 32 is fixedly disposed in the rectangular groove so that the lead screw assembly 32 is vertically disposed; the drive assembly 31 is fixedly mounted on the lead screw assembly 32, and its drive end is drivenly connected to the lead screw in the lead screw assembly 32 for driving the lead screw to rotate; one end of the first connecting member 33 is fixedly connected to one end of the lead screw for driving the first connecting member 33 to move up and down through the drive screw rotation of the drive assembly 31; the other end of the first connecting member 33 is used to fixably connect to the translation mechanism 40.

[0035] In this embodiment, the drive assembly 31 can drive the lead screw in the lead screw assembly 32 to rotate, thereby causing the first connecting member 33, which is fixedly connected to the upper end of the lead screw, to move in the vertical direction to adjust the height of the first connecting member 33. The first connecting member 33 is used to fixably connect to the translation mechanism 40, which is used to fixably connect to the clamping mechanism 50 used to hold the crystal ingot. Thus, when the drive mechanism drives the lead screw of the lead screw assembly 32 to rotate, the rotation of the lead screw can drive the first connecting member 33 to move in the vertical direction, thereby realizing the lifting and lowering of the crystal ingot in the vertical direction, adjusting the position of the crystal ingot in the vertical direction during crystal ingot handling, and ensuring the accuracy of crystal ingot handling.

[0036] In one embodiment, the translation mechanism 40 may include a U-shaped groove 41, a rack 42, a gear 43, a first transmission rod 44, a second transmission rod 45, and a second drive knob 46. One end of the U-shaped groove 41 is movably and fixedly connected to the lifting mechanism 30. The opening of the U-shaped groove 41 faces downward, and both sides of the opening have inwardly folded edges. The upper surfaces of the two first folded edges are provided with racks 42. The sides of the U-shaped groove 41 are symmetrically provided with horizontally oriented strip openings. Two gears 43 are sleeved on the first transmission rod. 3. It extends into the U-shaped groove 41 from one side of the strip opening and extends out from the other side of the strip opening. The two gears 43 are respectively meshed with the rack 42 on the first folded edge. The upper end of the second transmission rod 45 is connected to the first transmission rod 44 and is located between the two gears 43. The lower end of the second transmission rod 45 is used to fix the clamping mechanism 50. The second drive knob 46 is fixedly connected to one end of the first transmission rod 44 to drive the first transmission rod 44 to rotate, so as to drive the second drive rod to move along the rack 42.

[0037] In this embodiment, the translation mechanism 40 includes an inverted U-shaped groove 41. The opening of the U-shaped groove 41 is provided with an inwardly folded edge. A rack 42 is provided on the upper surface of both folded edges. A strip-shaped hole is opened on the side of the U-shaped groove 41, so that the first transmission rod 44 can enter from the strip-shaped hole on one side and exit from the strip-shaped hole on the other side, while being located inside the U-shaped groove 41. Two gears 43 are sleeved on the first transmission rod 44. These two gears 43 can respectively mesh with the racks 42 on the two folded edges. A second transmission rod 45 is provided on the first transmission rod 44 between the two gears 43. One end of the second transmission rod 45 is movably connected to the first transmission rod 44, and the other end is vertically downward and fixedly connected to the clamping mechanism 50. One end of the first transmission rod 44 is fixedly connected to a second drive knob 46. When the second drive knob 46 is turned, the first transmission rod 44 can be rotated. Since the gear 43 on the first transmission rod 44 meshes with the rack 42 on the folded edge, the translation mechanism 40 can move along the direction of the rack 42. Since the lower end of the second transmission rod 45 is fixedly connected to the clamping mechanism 50, and the clamping mechanism 50 holds the crystal rod, the translation mechanism 40 can drive the crystal rod to move horizontally.

[0038] Furthermore, in one embodiment, the second transmission rod 45 can also rotate 360°, thus enabling fine-tuning of the angle of the clamped crystal rod. For example, if there is a small deviation in the angle of the crystal rod during the clamping process of the crystal rod into the crystal rod chuck of the tumbling mill, the accuracy will be relatively low due to the relatively complex structure of the rotating mechanism 20. Therefore, the angle of the crystal rod can be fine-tuned by the second transmission rod 45, thereby accurately fixing the crystal rod on the crystal rod chuck of the tumbling mill.

[0039] In one embodiment, the clamping mechanism 50 may include: a first connecting rod 51, a second connecting rod 52, a third connecting rod 53, a fourth connecting rod 54, a second connecting member 55, a third connecting member 56, a first clamping member 57, and a second clamping member 58; both ends of the second connecting member 55 are movably connected to one end of the first connecting rod 51 and the second connecting rod 52, respectively, and the translation mechanism 40 is fixedly connected to the middle position of the second connecting member 55; the other end of the first connecting rod 51 is movably connected to one end of the third connecting rod 53, and the other end of the third connecting rod 53 is fixedly connected to the first clamping member 57; the other end of the second connecting rod 52 is movably connected to one end of the fourth connecting rod 54, and the other end of the fourth connecting rod 54 is fixedly connected to the second clamping member 58; both ends of the third connecting member 56 are movably connected to the middle positions of the third connecting rod 53 and the fourth connecting rod 54, respectively; the first clamping member 57 and the second clamping member 58 are both semi-circular structures with their inner arc surfaces facing each other, used to clamp the crystal rod to be tumbled.

[0040] In this embodiment, the first connecting rod 51, the second connecting rod 52, the third connecting rod 53, the fourth connecting rod 54, the second connecting member 55, and the third connecting member 56 in the clamping mechanism 50 can form an automatic opening and closing structure. When the lower ends of the first clamping member 57 and the second clamping member 58 are subjected to an upward force, the automatic opening and closing structure can be caused to contract upward, and the lower openings of the first clamping member 57 and the second clamping member 58 open, allowing the crystal rod to enter the first clamping member 57 and the second clamping member 58. After the crystal rod enters the first clamping member 57 and the second clamping member 58, the crystal rod will exert pressure on the inner surface of the lower end of the first clamping member 57 and the second clamping member 58 due to gravity, thereby causing the opening and closing structure to stretch downward. At this time, the lower openings of the first clamping member 57 and the second clamping member 58 close, achieving tight clamping of the crystal rod. Once the crystal ingot is transferred to the tumbling mill and secured to the ingot chuck, the first clamping member 57 and the second clamping member 58 can be opened again by applying upward pressure, allowing the clamping mechanism 50 to detach from the crystal ingot. Alternatively, the clamping mechanism 50 can be separated from the crystal ingot by manually applying upward pressure to the first clamping member 57 and the second clamping member 58, or by using an automatic opening and closing mechanism.

[0041] Furthermore, a second flange 59 is provided on the lower outer surface of both the first clamping member 57 and the second clamping member 58, and these two second flanges 59 can form an "eight"-shaped structure. Thus, when loading crystal rods from the crystal rod placement platform 80 or unloading crystal rods from the tumbling mill, it is only necessary to control the first clamping member 57 and the second clamping member 58 to be lowered from above the crystal rod. During the lowering process, the force applied to the two second flanges causes the first clamping member 57 and the second clamping member 58 to open, further avoiding manual operation by the operator and reducing safety hazards.

[0042] Because the clamping mechanism 50 may not clamp the crystal rod at its center when clamping it, the imbalance at both ends of the crystal rod may cause it to tilt, which increases the difficulty of handling and the risk of the crystal rod slipping. Therefore, in one embodiment, balancing components 70 are provided at the four corners of the outer surface of the first clamping member 57 and the four corners of the outer surface of the second clamping member 58. The balancing components 70 include a fixing member 71, a telescopic rod 72, and an expanding member 73. The fixing member 71 is a ring structure and is fixed at the corner of the outer surface of the clamping member. The telescopic rod 72 is movably disposed within the ring structure of the fixing member 71 and can extend and retract relative to the end face of the clamping component. The expanding member 73 is movably sleeved on the telescopic rod 72 and is located between the outer ends of the fixing member 71 and the telescopic rod 72.

[0043] In this embodiment, balancing components 70 are respectively provided at the four corners of the outer surfaces of the first clamping member 57 and the second clamping member 58. Each balancing component 70 consists of a fixing member 71, a telescopic rod 72, and an expanding member 73. The fixing member 71 is a ring structure, fixed to the outer surface of the clamping member, and is located within the fixing member 71 and can extend and retract within the fixing member 71. The expanding member 73 is sleeved on the outward side of the telescopic rod 72. Thus, when the crystal rod tilts during clamping by the first clamping member 57 and the second clamping member 58 of the clamping mechanism 50, the operator can extend the telescopic rod 72 of the corresponding balancing component 70 by a certain length, and adjust the balance of the crystal rod through the telescopic rod 72 and the expanding member 73 on the telescopic rod 72. For example, when the crystal rod tilts to the right during clamping, the operator can appropriately pull out the right telescopic rod 72 so that the expanding member 73 on the lower right end of the telescopic rod 72 contacts the crystal rod to form support, thereby achieving the purpose of adjusting the balance of the crystal rod.

[0044] Moreover, with the balancing component 70 provided in this solution, when there is an imbalance or tilting problem in the crystal rod clamping, the balance of the crystal rod can be adjusted by adjusting the balancing component 70, without having to abandon the clamping and find a new clamping point, thereby greatly improving the loading and unloading efficiency of the crystal rod grinding machine 60.

[0045] Of course, in order to avoid damage to the crystal rod by the clamping mechanism 50 during the loading and unloading process, the inner surfaces of the first clamping member 57 and the second clamping member 58, as well as the outer surfaces of each expansion member 73, are provided with anti-slip rubber. In this way, not only can damage to the crystal rod be avoided, but the friction between the clamping member and the crystal rod can also be increased, further reducing the risk of the crystal rod slipping.
