[0002] Monocrystalline silicon wafers are a fundamental material for the IC and solar industries. Currently, their production relies primarily on the Czochralski method (Czochralski) to pull single-crystal silicon ingots, followed by a series of process steps including cutting, tumbling, slicing, chamfering, grinding, etching, cleaning, and polishing.

[0003] An existing patent (publication number: CN105014536A) discloses a pre-tumbling alignment device for a crystal ingot. The device comprises a lower positioning mechanism, an intermediate chuck mechanism for clamping the crystal ingot, an upper positioning mechanism, and a column. The lower end of the column is fixed to one side of the lower positioning mechanism. The upper positioning mechanism is fixedly connected to the upper portion of the column via a suction cup base. A sliding sleeve in the middle of the column is equipped with a sleeve and a sleeve brake assembly to control the sleeve's sliding on the column. The intermediate chuck mechanism is secured to the sleeve via a chuck fixing plate. This device clamps the crystal ingot with the intermediate chuck mechanism, then uses the upper and lower positioning mechanisms to position the ingot. Centering blocks are then bonded to each end of the ingot. This device addresses the high level of operator experience and skill required for centering the ingot and bonding the centering blocks. It also effectively avoids misalignment between the ingot and the centering blocks due to subjective errors, significantly improving production efficiency, ensuring product quality, and reducing production costs.

[0012] Preferably, the method for using the crystal ingot positioning mechanism for crystal ingot processing comprises the following steps:

[0013] S1: The crystal ingot to be processed is placed in the placement slot on the supporting platform, and the processing plate is installed with a processing machine for performing operations such as grinding and polishing on the crystal ingot. When processing the crystal ingot, the driving motor drives the driving bevel gear to rotate, and the rotation of the driving bevel gear can synchronously drive the two transmission bevel gears to rotate. The rotation directions of the two transmission bevel gears are different. At this time, the adjustment frame is deflected on the top of the supporting platform. After the adjustment frame is deflected, the adjustment block arranged at one end of the adjustment sleeve rod will drive the adjustment sleeve rod to slide on the driving rod. Due to the friction between the end face of the adjustment sleeve rod and the transmission bevel gear, when the adjustment sleeve rod contacts the transmission bevel gear, the rotation of the transmission bevel gear will drive the adjustment sleeve rod to rotate, and the rotation of the adjustment sleeve rod will drive the driving rod to rotate. The two ends of the driving rod extend toward the two moving devices on the supporting platform respectively, and when the driving rod rotates, the moving device can move, so that the moving device can adjust the moving distance of the crystal ingot;

[0014] S2: When the crystal ingot is being processed, the crystal ingot is first placed in the placement slot on the carrier, and the crystal plate is placed on the top surface of the support plate. When the crystal ingot is being processed, the initial position of the moving rod is located in the wedge-shaped slide groove in one of the limit frames. At this time, the positioning frame is pressed against the outer wall of the crystal ingot, so that the crystal ingot is in a fixed state, so that the crystal ingot can be processed stably. After the crystal ingot is processed, when the moving position of the crystal ingot needs to be adjusted, the driving device drives the driving rod to rotate, and the driving rod drives the one-way shaft to rotate the reciprocating screw rod, and the reciprocating screw rod drives the moving block to slide on the moving frame. Since the two positioning rods extend into the support plate, when the moving block moves, the support plate can be driven to move through the two positioning rods, thereby adjusting the movement of the fixed crystal ingot. When the moving block is reset, the moving block resets and drives the supporting plate to reset through the two positioning rods, but does not drive the crystal rod to move. After the moving block is reset, the moving rod contacts the limiting frame close to one end of the driving rod again, thereby continuing to fix the crystal rod.

[0015] S3: When the moving device and the positioning device cooperate to drive the crystal rod to move toward the processing plate, the rotating gear and the fixed rack are not on the same axis and the two do not contact. When the moving block on the moving device is reset, the crystal rod will not move. When the moving rod moves driven by the wedge-shaped slide, the moving rod will move the rotating gear on the rotating rod toward the fixed rack through the clamping frame. At this time, the rotating gear and the fixed rack are engaged. Then, when the moving frame is reset, the rotating gear will rotate under the restriction of the fixed rack. The rotation of the rotating gear drives the rotating rod to rotate. The end of the rotating rod away from the rotating gear will drive the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to rotate. The first bevel gear drives the support rod to rotate. The support rod will cause the cleaning brush to clean the surface of the crystal rod and the waste chips after processing in the placement groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, a crystal ingot to be processed is placed in a placement groove on a carrier platform, and a processing plate is installed with a processing machine for performing operations such as grinding and polishing on the crystal ingot. When processing the crystal ingot, a driving motor drives a driving bevel gear to rotate. The rotation of the driving bevel gear can synchronously drive two transmission bevel gears to rotate. The rotation directions of the two transmission bevel gears are different. At this time, the adjustment frame is deflected on the top of the carrier platform. After the adjustment frame is deflected, an adjustment block arranged toward one end of the adjustment sleeve rod drives the adjustment sleeve rod to slide on the driving rod. Due to the friction between the end surface of the adjustment sleeve rod and the transmission bevel gear, when the adjustment sleeve rod contacts the transmission bevel gear, the rotation of the transmission bevel gear drives the adjustment sleeve rod to rotate, and the rotation of the adjustment sleeve rod drives the driving rod to rotate. The two ends of the driving rod extend toward the two moving devices on the carrier platform respectively. When the driving rod rotates, the moving device can move, so that the moving device can adjust the moving distance of the crystal ingot. The two transmission bevel gears respectively drive the driving rod to realize forward and reverse rotation, thereby respectively driving the two moving devices to move, thereby facilitating the adjustment of the distance between the two ends of the crystal ingot, and making the efficiency of crystal ingot processing higher.

[0018] In the present invention, when the crystal ingot is processed, the crystal ingot is first placed in the placement groove on the supporting table, and the crystal plate is placed on the top surface of the support plate. When the crystal ingot is being processed, the initial position of the moving rod is located in the wedge-shaped slide groove in one of the limit frames. At this time, the positioning frame is pressed against the outer wall of the crystal ingot, so that the crystal ingot is in a fixed state, so that the crystal ingot can be processed stably. After the crystal ingot is processed, when the moving position of the crystal ingot needs to be adjusted, the driving rod is rotated under the drive of the driving device, and the driving rod drives the unidirectional shaft to rotate the reciprocating screw rod, and the reciprocating screw rod drives the moving block to slide on the moving frame. Since the two positioning rods extend into the support plate, when the moving block moves, the support plate can be driven to move through the two positioning rods, thereby adjusting the fixed crystal ingot to move, so that the crystal ingot can be adjusted in position, and when the reciprocating screw rod drives the moving block to move to another limit frame, the moving rod will contact the other limit frame. When the two levers are in contact with each other, the two levers will move upwards to push the two levers back into contact with the support plate, thereby releasing the fixation of the crystal rod. At this time, when the movable block is reset under the drive of the reciprocating screw, the movable block resets and drives the support plate to reset through the two positioning rods without driving the crystal rod to move. After the movable block is reset, the movable rod contacts the limit frame close to one end of the driving rod again, thereby continuing to fix the crystal rod. Through this arrangement, when the crystal rod needs to be moved during processing, the cooperation of the moving device and the positioning device enables the crystal rod to continuously and intermittently move toward the processing plate, thereby improving the efficiency of crystal rod processing, and the crystal rod can be positioned after movement, so that the crystal rod can be processed stably.

[0019] When the movable block on the movable device is reset, the crystal rod will not move, and the movable rod will move under the drive of the wedge-shaped slide groove, and the movable rod will make the rotating gear move on the rotating rod toward the fixed rack through the clamping frame. At this time, the rotating gear and the fixed rack are meshed, and then when the movable frame is reset, the rotating gear will rotate under the restriction of the fixed rack, and the rotating gear will drive the rotating rod to rotate. The end of the rotating rod away from the rotating gear will drive the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the support rod to rotate, and the support rod will cause the cleaning brush to clean the surface of the crystal rod and the waste chips after processing in the placement groove, so that the waste chips generated can be effectively cleaned during the processing and positioning of the crystal rod.

[0031] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the driving device 2 includes a driving motor 21 fixedly connected to the top of the carrier 1. The main shaft of the driving motor 21 is connected to the driving bevel gear 22. The top of the carrier 1 is provided with a driving bevel gear 23 for corresponding rotation.

At this time, the adjustment frame 33 is deflected on the top of the supporting platform 1. After the adjustment frame 33 is deflected, the adjustment block 34 set at one end of the adjustment sleeve rod 32 will drive the adjustment sleeve rod 32 to slide on the driving rod 31. Due to the end face of the adjustment sleeve rod 32 and the transmission bevel gear 23, the adjustment block 34 will drive the adjustment sleeve rod 32 to slide on the driving rod 31. The two helical gears 23 respectively drive the driving rod 31 to rotate, thereby facilitating the adjustment of the distance between the two ends of the crystal rod and the moving device 4.

[0034] In this embodiment, Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the two moving devices 4 each include a moving frame 41 fixedly connected to the top of the carrier platform 1, a reciprocating screw rod 42 is rotatably provided on the moving frame 41, and a one-way shaft is connected to the end of the reciprocating screw rod 42 facing the driving rod 31, and the one-way shaft is axially connected to the driving rod 31, and a moving block 43 is slidably provided on the moving frame 41, and the moving block 43 is spirally engaged with the reciprocating screw rod 42;

[0035] The positioning device 5 includes two limiting frames 44 fixedly connected to the top of the moving frame 41 and arranged opposite to each other. The two moving frames 41 are each provided with a wedge-shaped slide 441. A moving rod 45 is slidably provided on the top of the moving block 43, and the moving rod 45 contacts the wedge-shaped slide 441 on the moving frame 41.

[0036] The positioning device 5 also includes a pushing frame 51 fixedly connected to the moving rod 45, and the pushing frame 51 is arranged in the direction of the placement groove 11. The moving block 43 is fixedly connected to a fixed plate 52 on the outer wall of the placement groove 11, and a positioning rod 53 is correspondingly slidably provided on the fixed plate 52. The upper end of the positioning rod 53 is fixedly connected to a positioning plate 54, and a hinged frame 55 is hingedly provided between the positioning plate 54 and the pushing frame 51.

The two positioning rods 53 are also fixedly connected to a positioning frame 57, and the positioning frame 57 is located above the supporting plate 56;

[0037] When the crystal ingot is being processed, the crystal ingot is first placed in the placement groove 11 on the carrier 1, and the crystal plate is placed on the top surface of the support plate 56. When the crystal ingot is being processed, the initial position of the moving rod 45 is located in the wedge-shaped slide groove 441 in one of the limit frames 44. At this time, the positioning frame 57 is pressed against the outer wall of the crystal ingot, so that the crystal ingot is in a fixed state, so that the crystal ingot can be processed stably. When the moving position of the crystal ingot needs to be adjusted after processing, the driving device 2 is driven to rotate the driving rod 31, and the driving rod 31 is rotated. The one-way shaft is driven to rotate the reciprocating screw 42, and the reciprocating screw 42 drives the moving block 43 to slide on the moving frame 41. Since the two positioning rods 53 extend into the support plate 56, when the moving block 43 moves, the support plate 56 can be driven to move by the two positioning rods 53, thereby adjusting the movement of the fixed crystal rod, so that the position of the crystal rod can be adjusted.

When the moving block 43 is reset, the moving block 43 is reset by driving the two positioning rods 53 to drive the supporting plate 56 to reset, but it does not drive the crystal ingot to move. After the moving block 43 is reset, the moving rod 45 is again in contact with the limiting frame 44 near one end of the driving rod 31, thereby continuing to fix the crystal ingot. Through this arrangement, when the crystal ingot needs to be moved during the processing, the moving device 4 and the positioning device 5 cooperate to enable the crystal ingot to be continuously and intermittently moved toward the processing plate 12, thereby improving the efficiency of the crystal ingot processing. After the movement, the crystal ingot can be positioned so that the crystal ingot can be processed stably.

The bottom of the moving rod 45 is also fixedly connected to a clamping frame 64, which is arranged in the direction of the rotating gear 62 and rotates in conjunction with the rotating gear 62.

[0039] The cleaning device 6 further includes a first bevel gear 65 rotatably mounted on the fixed plate 52. An end of the rotating rod 61 away from the rotating gear 62 is fixedly connected to a second bevel gear 66. The first bevel gear 65 meshes with the second bevel gear 66. A support rod 67 is fixedly mounted on the first bevel gear 65. A cleaning brush 68 is mounted on the support rod 67. The cleaning brush 68 is located above the placement slot 11.

[0040] When the moving device 4 and the positioning device 5 cooperate to drive the crystal rod to move toward the processing plate 12, the rotating gear 62 and the fixed rack 63 are not on the same axis, and the two do not contact each other. When the moving block 43 on the moving device 4 is reset, the crystal rod will not move. When the moving rod 45 moves under the drive of the wedge-shaped slide 441, the moving rod 45 will move the rotating gear 62 on the rotating rod 61 toward the fixed rack 63 through the clamping frame 64. At this time, the rotating gear 62 and the fixed rack 63 are engaged, and then when the moving frame 41 is reset, the crystal rod will not move. During the positioning process, the rotating gear 62 will rotate under the restriction of the fixed rack 63, and the rotation of the rotating gear 62 will drive the rotating rod 61 to rotate. The end of the rotating rod 61 away from the rotating gear 62 will drive the second bevel gear 66 to rotate, and the second bevel gear 66 drives the first bevel gear 65 to rotate. The first bevel gear 65 drives the support rod 67 to rotate, and the support rod 67 will cause the cleaning brush 68 to clean the surface of the crystal rod and the waste chips after processing in the placement groove 11, so that the waste chips generated can be effectively cleaned during the processing and positioning of the crystal rod.

[0041] The use method and advantages of the present invention: The use method of the crystal ingot positioning mechanism for crystal ingot processing, the working process is as follows:

[0042] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown:

[0043] S1: The crystal ingot to be processed is placed in the placement groove 11 on the supporting platform 1. The processing plate 12 is installed with a processing machine for grinding, polishing, etc. on the crystal ingot. When processing the crystal ingot, the driving motor 21 drives the driving bevel gear 22 to rotate. The rotation of the driving bevel gear 22 can synchronously drive the two transmission bevel gears 23 to rotate. The rotation directions of the two transmission bevel gears 23 are different. At this time, the adjustment frame 33 is deflected on the top of the supporting platform 1. After the adjustment frame 33 is deflected, the adjustment block 34 set at one end of the adjustment sleeve rod 32 will bring The movable adjustment sleeve 32 slides on the driving rod 31. Due to the friction between the end surface of the adjustment sleeve 32 and the transmission bevel gear 23, when the adjustment sleeve 32 contacts the transmission bevel gear 23, the transmission bevel gear 23 rotates, which drives the adjustment sleeve 32 to rotate. The rotation of the adjustment sleeve 32 drives the driving rod 31 to rotate. The two ends of the driving rod 31 extend toward the two moving devices 4 on the supporting platform 1 respectively. When the driving rod 31 rotates, the moving device 4 can move, so that the moving device 4 can adjust the moving distance of the crystal ingot.

[0044] S2: When the crystal rod is being processed, the crystal rod is first placed in the placement groove 11 on the supporting platform 1, and the crystal plate is placed on the top surface of the support plate 56. When the crystal rod is being processed, the initial position of the moving rod 45 is located in the wedge-shaped slide groove 441 in one of the limit frames 44. At this time, the positioning frame 57 is pressed onto the outer wall of the crystal rod, so that the crystal rod is in a fixed state, so that the crystal rod can be processed stably. When the moving position of the crystal rod needs to be adjusted after processing, the driving rod 31 is rotated under the drive of the driving device 2, and the driving rod 31 drives the unidirectional shaft to rotate the reciprocating screw 42, and the reciprocating screw 42 drives the moving block 43 to slide on the moving frame 41. Since the two positioning rods 53 extend into the support plate 56, when the moving block 43 moves, the support plate 56 can be driven to move through the two positioning rods 53, thereby adjusting the fixed crystal rod to move so that the crystal rod can be positioned. When the moving block 43 is reset, the moving block 43 is reset and the supporting plate 56 is reset by the two positioning rods 53, but the crystal rod is not moved. After the moving block 43 is reset, the moving rod 45 is in contact with the limiting frame 44 near one end of the driving rod 31 again, thereby continuing to fix the crystal rod.

[0045] When the moving block 43 on the moving device 4 is reset, the crystal rod will not move, and the moving rod 45 will move under the drive of the wedge-shaped slide groove 441, and the moving rod 45 will make the rotating gear 62 move on the rotating rod 61 toward the fixed rack 63 through the clamping frame 64. At this time, the rotating gear 62 and the fixed rack 63 are meshed, and then when the moving frame 41 is reset, the rotating gear 62 will rotate under the restriction of the fixed rack 63, and the rotating gear 62 will drive the rotating rod 61 to rotate. The end of the rotating rod 61 away from the rotating gear 62 will drive the second bevel gear 66 to rotate, and the second bevel gear 66 drives the first bevel gear 65 to rotate, and the first bevel gear 65 drives the support rod 67 to rotate, and the support rod 67 will cause the cleaning brush 68 to clean the surface of the crystal rod and the waste chips after processing in the placement groove 11.

5. The method for using the crystal ingot positioning mechanism for crystal ingot processing according to claim 4, comprising the following steps: S1: The crystal ingot to be processed is placed in the placement slot on the supporting platform, and the processing plate is installed with a processing machine for performing operations such as grinding and polishing on the crystal ingot. When processing the crystal ingot, the driving motor drives the driving bevel gear to rotate, and the rotation of the driving bevel gear can synchronously drive the two transmission bevel gears to rotate. The rotation directions of the two transmission bevel gears are different. At this time, the adjustment frame is deflected on the top of the supporting platform. After the adjustment frame is deflected, the adjustment block arranged at one end of the adjustment sleeve rod will drive the adjustment sleeve rod to slide on the driving rod. Due to the friction between the end face of the adjustment sleeve rod and the transmission bevel gear, when the adjustment sleeve rod contacts the transmission bevel gear, the rotation of the transmission bevel gear will drive the adjustment sleeve rod to rotate, and the rotation of the adjustment sleeve rod will drive the driving rod to rotate. The two ends of the driving rod extend toward the two moving devices on the supporting platform respectively, and when the driving rod rotates, the moving device can move, so that the moving device can adjust the moving distance of the crystal ingot; S2: When the crystal ingot is being processed, the crystal ingot is first placed in the placement slot on the carrier, and the crystal plate is placed on the top surface of the support plate. When the crystal ingot is being processed, the initial position of the moving rod is located in the wedge-shaped slide groove in one of the limit frames. At this time, the positioning frame is pressed against the outer wall of the crystal ingot, so that the crystal ingot is in a fixed state, so that the crystal ingot can be processed stably. After the crystal ingot is processed, when the moving position of the crystal ingot needs to be adjusted, the driving device drives the driving rod to rotate, and the driving rod drives the one-way shaft to rotate the reciprocating screw rod, and the reciprocating screw rod drives the moving block to slide on the moving frame. Since the two positioning rods extend into the support plate, when the moving block moves, the support plate can be driven to move through the two positioning rods, thereby adjusting the movement of the fixed crystal ingot. When the moving block is reset, the moving block resets and drives the supporting plate to reset through the two positioning rods, but does not drive the crystal rod to move. After the moving block is reset, the moving rod contacts the limiting frame close to one end of the driving rod again, thereby continuing to fix the crystal rod. S3: When the moving device and the positioning device cooperate to drive the crystal rod to move toward the processing plate, the rotating gear and the fixed rack are not on the same axis and the two do not contact. When the moving block on the moving device is reset, the crystal rod will not move. When the moving rod moves driven by the wedge-shaped slide, the moving rod will move the rotating gear on the rotating rod toward the fixed rack through the clamping frame. At this time, the rotating gear and the fixed rack are engaged. Then, when the moving frame is reset, the rotating gear will rotate under the restriction of the fixed rack. The rotation of the rotating gear drives the rotating rod to rotate. The end of the rotating rod away from the rotating gear will drive the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to rotate. The first bevel gear drives the support rod to rotate. The support rod will cause the cleaning brush to clean the surface of the crystal rod and the waste chips after processing in the placement groove.
