Description

Technical Field

[0001] This utility model relates to the field of silicon rod processing technology, and in particular to a square silicon rod loading and unloading slide and a multi-station square silicon rod grinding machine device. Background Technology

[0002] After forming, squared silicon rods typically require precision grinding to remove surface damage layers, control dimensional tolerances, and improve edge morphology. When transferring the squared silicon rods to the grinding mechanism, the inherent dimensional tolerances and form errors of the incoming rods make it difficult for simple clamping and transport to ensure precise alignment between the centers of both ends and the clamping centers of the grinding mechanism's jaws. This alignment deviation leads to uneven grinding allowance: one end may be over-ground, resulting in material waste and potentially cracks; the other end may be under-ground, leaving a damaged layer. More seriously, uneven force during grinding can cause edge chipping or even breakage of the silicon rod, resulting in costly material scrap. This constraint on precision and consistency limits the reduction of production cycle time and the improvement of overall automation levels, and introduces significant quality risks. Therefore, there is an urgent need for a loading and unloading device that can guarantee the accuracy of squared silicon rod loading and unloading. Utility Model Content

Detailed Implementation

[0017] To better explain and facilitate understanding of this utility model, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, is provided. Specifically, the first direction mentioned herein refers to... Figure 1 Using the "Y" direction as a reference, the second direction is based on... Figure 1 Using the "X" direction as a reference, "up" and "down" are... Figure 5 The orientation is used as a reference.

[0018] Example 1 See Figure 1-10 This embodiment provides a squaring silicon rod loading and unloading slide, which includes a material platform 32, a horizontal adjustment component 33, a vertical adjustment component 34, and a lifting component 35.

[0019] The material table 32 includes a support platform 321, a first clamping plate 322, and a second clamping plate 323. The support platform 321 extends along a first horizontal direction and is used to support a horizontally oriented square silicon rod A. The first clamping plate 322 and the second clamping plate 323 are located on both sides of the support platform 321 in the width direction and can move closer or further apart to clamp or release the square silicon rod A.

[0020] The horizontal adjustment component 33 drives the second clamping plate 323 to rotate horizontally relative to the first clamping plate 322, thereby causing the two ends of the square silicon rod A in the clamped state to swing horizontally, thus adjusting the horizontal direction of the square silicon rod A. The vertical adjustment component 34 drives the support platform 321 to swing up and down, thereby causing the two ends of the supported square silicon rod A to swing up and down, thus adjusting the vertical direction of the square silicon rod A. The lifting component 35 drives the support platform 321 to lift the supported square silicon rod A as a whole, thereby adjusting the height of the silicon rod.

[0021] After adjustment, the centers of both ends of the square silicon rod A can be made to correspond to the clamping centers of the two jaws 221 in the horizontal, vertical and height directions, thereby adjusting the centers of both ends of the square silicon rod A to be consistent with the clamping centers of the two jaws 221 and aligned with the positioning center of the grinding mechanism 2.

[0022] Therefore, the silicon rod loading and unloading slide achieves precise automatic centering, greatly improving grinding accuracy and consistency. The core advantage of this slide lies in its three-in-one adjustment capability. Through the horizontal adjustment component 33 and the vertical adjustment component 34, the two ends of the silicon rod A can be driven to swing horizontally and vertically, respectively. Combined with the overall height adjustment of the lifting component 35, it can actively compensate for the dimensional and positional errors of the incoming silicon rod. This ensures that the centers of the two ends of the silicon rod A are precisely adjusted in the horizontal, vertical, and height directions to be completely aligned with the clamping centers of the two jaws 221 of the grinding mechanism 2. This precise centering ensures that the axis of the silicon rod A perfectly coincides with the positioning center of the grinding mechanism 2, thereby ensuring that the grinding amount is uniform throughout the grinding process, effectively avoiding over-grinding or under-grinding on one side, and significantly improving the dimensional accuracy, straightness, and surface quality of the silicon rod A.

[0023] Furthermore, to achieve horizontal adjustment of the squared silicon rod A, this embodiment further specifies: A first pressing block 3221 is provided at the middle of the inner wall of the first clamping plate 322 along its length. At least one set of second pressing portions is provided on the inner wall of the second clamping plate 323, each set including two second pressing blocks 3231 spaced apart along its length. The first pressing block 3221 and the two second pressing blocks 3231 can clamp the two sides of the square silicon rod A to form a three-point abutment, creating an abutment plane. This allows for compensation of dimensional errors in the square silicon rod A caused by manufacturing defects during clamping, thereby enabling stable clamping of the square silicon rod A.

[0024] The horizontal adjustment component 33 is driven to connect to the second clamping plate 323. When the second clamping plate 323 rotates horizontally, the two second pressing blocks 3231 drive the clamped square silicon rod A to swing horizontally around the first pressing block 3221, so as to precisely control the angle of the long square silicon rod A on the horizontal plane.

[0025] It should be noted that, relative to the longer square silicon rod A, the first pressing block 3221 and the square silicon rod A can be regarded as point contact, which can support the square silicon rod A to swing horizontally around the first pressing block 3221.

[0026] Specifically, to accommodate the clamping and adjustment of the horizontal angle of silicon rods A of different lengths, this embodiment further defines: The inner wall of the second clamping plate 323 is provided with two sets of second pressing parts. The first set of second pressing parts is located at both ends of the second clamping plate 323 in the length direction, and the second set of second pressing parts is located between the first set. The thickness of the first set of second pressing parts is greater than that of the second set of second pressing parts.

[0027] When it is necessary to clamp a long silicon rod A, the first group of second pressing parts located on the outer side can abut against both ends of the side of the silicon rod A, and the second group of second pressing parts does not contact the silicon rod A. The first group of second pressing parts can provide a long lever arm to drive the clamped square silicon rod A to swing horizontally around the first pressing block 3221.

[0028] When a shorter silicon rod A needs to be clamped, the second set of second pressing parts located relatively inside abut against the two ends of the side of the silicon rod A. The second set of second pressing parts can provide a shorter lever arm to act on the two ends of the side of the silicon rod A and drive the clamped square silicon rod A to swing horizontally around the first pressing block 3221.

[0029] It should be noted that the length of the lever arm acting on silicon rod A to push it to swing horizontally around the vertical axis varies for silicon rod A of different lengths. This application provides two sets of second pressing parts, which can provide the required rotation lever arm for silicon rod A of different lengths.

[0030] Optionally, the first set of second pressing parts is suitable for clamping silicon rod A with a length of 600-950 mm and a width of 210 mm. The length of the two second pressing blocks 3231 of the first set of second pressing parts is 20-40 mm, preferably 30 mm. The distance between the two second pressing blocks 3231 is 550-600 mm, preferably 600 mm.

[0031] The second set of second pressing parts is suitable for clamping silicon rods A with a length of 300-400mm and a width of 158-240mm. The length of the two second pressing blocks 3231 of the second set of second pressing parts is 140-160mm, preferably 150mm. The distance between the two second pressing blocks 3231 is 40-60mm, preferably 50mm. The length of the second pressing blocks 3231 is relatively long to expand the range of lengths of silicon rods A that can be clamped.

[0032] Preferably, in order to optimize the rotation of the square silicon rod A around the first pressing block 3221, the first pressing block 3221 includes a main body 32211 and a boss 32212 disposed in the middle of the main body in the length direction, the boss 32212 forming a pivot center supporting the rotation of the silicon rod A.

[0033] The length of the boss 32212 is preferably set to 15mm, the length of the body 32211 is preferably set to 40mm, and the thickness of the boss 32212 and the body 32211 is preferably less than or equal to 3mm. This combination of dimensions is designed to ensure that when the squared silicon rod A rotates around the boss 32212, there is always a gap between the side of the squared silicon rod A and the body 32211, thereby avoiding interference and jamming caused by contact.

[0034] It should be noted that the above numerical settings are only preferred embodiments and are not intended to be limiting. They can be adjusted accordingly based on the actual situation.

[0035] Specifically, the feed table 32 includes a first adjustment seat 3222 and a second adjustment seat 3232 that can move closer to each other or further away from each other.

[0036] The first clamping plate 322 is fixed to the first adjusting seat 3222, and the second clamping plate 323 is hinged to the second adjusting seat 3232 around a vertical axis at its middle length. The first adjusting seat 3222 and the second adjusting seat 3232 drive the first clamping plate 322 and the second clamping plate 323 to move closer together or further apart.

[0037] The support platform 321 is located between the first adjustment seat 3222 and the second adjustment seat 3232.

[0038] Specifically, the horizontal adjustment component 33 includes a first wedge block 331, a first elastic element 332, a first telescopic drive element 333, and a first push block 334.

[0039] The first wedge block 331 is disposed on the outer wall of one end of the second clamping plate 323 along its length. The first elastic member 332 is horizontally oriented along the second horizontal direction, and its two ends are respectively connected to the outer wall of the second clamping plate 323 and the second adjusting seat 3232. The main body of the first telescopic drive member 333 is fixed on the second adjusting seat 3232, and the drive end is connected to the first push block 334. The first push block 334 and the first wedge block 331 are slidably engaged by inclined surfaces.

[0040] The driving end of the first telescopic drive member 333 can drive the first push block 334 to move along the first horizontal direction. The first push block 334 moves along the inclined surface of the first wedge block 331, so that the second clamping plate 323 swings horizontally. When the first push block 334 moves along the high position of the first wedge block 331, the first push block 334 can push the first wedge block 331 to cause the first end of the second clamping plate 323 to swing horizontally away from the first push block 334, and the first elastic member 332 is compressed or stretched. When the first push block 334 moves towards the low position of the first wedge block 331, the first elastic member 332 returns to its original position and pushes the first end of the second clamping plate 323 to swing horizontally towards the first push block 334.

[0041] During this process, the first telescopic drive member 333 and the first push block 334 can support the second clamping plate 323 to stably support the second clamping plate 323, which, combined with the flexible restoring force provided by the first elastic member 332, enables the second clamping plate 323 to stably clamp the square silicon rod A when adjusting the horizontal angle of the square silicon rod A.

[0042] Optionally, the first telescopic drive component 333 includes a first motor 3331, a first lead screw 3332, and a first nut 3333. The main body of the first motor 3331 is fixed on the second adjusting seat 3232, and the drive end is connected to the first lead screw 3332. The first lead screw 3332 extends along a first horizontal direction, and the first nut 3333 is sleeved on the first lead screw 3332. The first nut 3333 is fixedly connected to the first push block 334. The first motor 3331 drives the first lead screw 3332 to rotate, and the first nut 3333 moves along the first lead screw 3332 to drive the first push block 334 to move along the first horizontal direction.

[0043] Based on the above configuration, the inclined plane mechanism composed of the first wedge block 331 and the first push block 334 can convert the precise linear displacement of the first telescopic drive member 333 into a controllable swing angle, so as to fine-tune the horizontal angle of the silicon rod A and lock it firmly in the target position after adjustment. At the same time, the cooperation between the first telescopic drive member 333 and the inclined plane mechanism can reduce the size of the horizontal adjustment component 33.

[0044] Furthermore, to achieve adjustment of the vertical direction and height position of the square silicon rod A, this embodiment further specifies: The support platform 321 includes a support plate 3211, a support plate base 3212, and a support base 3213. The support plate 3211 extends along a first horizontal direction, and its middle portion in the length direction is rotatably hinged to the top of the support plate base 3212 about a horizontal axis. The support plate 3211 is used to support a horizontally oriented square silicon rod A. The support plate base 3212 is vertically and vertically positioned above the support base 3213. The vertical adjustment component 34 drives the support plate 3211 to swing up and down about the horizontal axis, thereby causing the two ends of the supported square silicon rod A to swing up and down relative to the support plate base 3212, so as to adjust the angle of the vertical swing of the square silicon rod A. The lifting component 35 drives the support plate base 3212 to move the support plate 3211 and the supported square silicon rod A up and down relative to the support base 3213, so as to adjust the overall height of the square silicon rod A.

[0045] Based on the above configuration, the support platform 321 can support the square silicon rod A and adjust the vertical angle and height of the square silicon rod A. It also has a compact structure and small size.

[0046] It should be noted that after the support plate 3211 receives the square silicon rod A to be ground, the vertical adjustment component 34 and the lifting component 35 adjust the vertical angle and height position of the square silicon rod A in sequence. Then, the first clamping plate 322 and the second clamping plate 323 clamp the two horizontal sides of the square silicon rod A, and then adjust the horizontal angle of the square silicon rod A to avoid interference between the adjustment processes.

[0047] Furthermore, the specific settings for the vertical adjustment component 34 are as follows: The vertical adjustment assembly 34 includes a second wedge block 341, a second elastic element, a second telescopic drive element 342, and a second push block 343.

[0048] The second wedge block 341 is located at the bottom of one end of the support plate 3211 along its length. The two ends of the vertically oriented second elastic member are respectively connected to the bottom of the support plate 3211 and the support plate seat 3212. The main body of the second telescopic drive member 342 is fixed to the support plate seat 3212, and its drive end is connected to the second push block 343. The second push block 343 and the second wedge block 341 are slidably engaged via inclined surfaces. The drive end of the second telescopic drive member 342 can drive the second push block 343 to move along the second horizontal direction, so that the second push block 343 moves along the inclined surface of the second wedge block 341. The support plate 3211 causes the two ends of the supported square silicon rod A to swing up and down relative to the support plate seat 3212. Its specific working principle is as follows: When the second pushing block 343 moves to the higher position of the second wedge block 341, the first pushing block 334 can push the second wedge block 341 to cause the first end of the support plate 3211 to swing upward, and the elastic element is compressed or stretched. When the second pushing block 343 moves to the lower position of the second wedge block 341, the elastic element returns to its original position and pushes the first end of the support plate 3211 to swing downward.

[0049] During this process, the second telescopic drive member 342 and the second push block 343 can support the support plate 3211, and the elastic member can combine with the flexible restoring force provided by the first elastic member 332 so that the support plate 3211 can stably support the square silicon rod A when adjusting the vertical angle of the square silicon rod A.

[0050] Optionally, the second telescopic drive component 342 includes a second motor 3421, a second lead screw 3422, and a second nut 3423. The main body of the second motor 3421 is fixed on the support plate 3212, and the drive end is connected to the second lead screw 3422. The second lead screw 3422 extends along the second horizontal direction, and the second nut 3423 is sleeved on the lead screw 111. The second nut 3423 is fixedly connected to the second push block 343.

[0051] The second motor 3421 is used to drive the second lead screw 3422 to rotate, and the second nut 3423 moves along the second lead screw 3422 to drive the second push block 343 to move in the second horizontal direction.

[0052] This setting improves the accuracy of driving the second push block 343 to move.

[0053] Based on the above configuration, the inclined plane mechanism composed of the second wedge block 341 and the second push block 343 can convert the precise linear displacement of the second telescopic drive member 342 into a controllable swing angle, so as to fine-tune the vertical angle of the silicon rod A and lock it firmly in the target position after adjustment. At the same time, the cooperation between the second telescopic drive member 342 and the inclined plane mechanism can reduce the size of the vertical adjustment component 34.

[0054] Furthermore, the specific configuration of the lifting component 35 is as follows: The lifting assembly 35 includes a roller 351, a third push block 352, and a third telescopic drive component 353.

[0055] The roller 351 is located at the bottom of the support plate 3212. The third pushing block 352 is slidably engaged with the support base 3213, and its top is inclined. The top of the third pushing block 352 and the roller 351 are in rolling engagement. The main body of the third telescopic drive member 353 is fixed to the support base 3213, and its drive end is connected to the third pushing block 352.

[0056] The driving end of the third telescopic drive member 353 can drive the third push block 352 to move along the first horizontal direction. The third push block 352 pushes the roller 351 to rise and fall. When the top of the third push block 352 moves from low to high relative to the roller 351, the roller 351 rises. When the top of the third push block 352 moves from high to low relative to the roller 351, the roller 351 falls, so that the support plate 3211 and the support plate seat 3212 drive the supported square silicon rod A to rise and fall synchronously relative to the support seat 3213.

[0057] Specifically, a key 354 extending along a first horizontal direction is provided on the top of the support base 3213, and a keyway that slides with the key 354 is provided on the bottom of the third push block 352. The third telescopic drive member 353 is located below the support base 3213. An insertion hole is provided on the support base 3213, and a connecting block 355 fixed to the third push block 352 passes through the insertion hole and connects to the drive end of the third telescopic drive member 353. The connecting block 355 can move relative to the insertion hole along the first horizontal direction. The drive end of the third telescopic drive member 353 drives the third push block 352 to move relative to the support base 3213 along the first horizontal direction through the connecting block 355.

[0058] Based on the above configuration, by placing the third push block 352 above the support base 3213 and placing the third telescopic drive member 353 below the support base 3213, and by using the key 354 and the key 354 groove to engage the bottom of the third push block 352 and the top of the support base 3213, the overall height and volume of the support platform 321 can be further reduced.

[0059] Preferably, to improve the adjustment accuracy of the height position of the squared silicon rod A, this embodiment further specifies: An elongated through hole 3551 extending along the first horizontal direction is provided on the connecting block 355, and a guide plate 356 is provided at the bottom of the support plate 3212.

[0060] A vertical guide rod 357 is provided on the guide plate 356, and a guide hole 3561 is provided on the support base 3213. The guide rod 357 can be inserted into the guide hole 3561 in a vertically adjustable manner. Figure 9 As shown; or, a guide hole 3561 is provided on the guide plate 356, and a vertical guide rod 357 is fixedly provided on the support base 3213. The guide hole 3561 is sleeved on the guide rod 357 and can be raised and lowered relative to the guide rod 357.

[0061] The elongated through hole 3551 can move relative to the guide rod 357 in the first horizontal direction.

[0062] When the third push block 352 drives the connecting block 355 to move relative to the support base 3213 in the first horizontal direction, the elongated through hole 3551 can move relative to the guide rod 357 in the first horizontal direction. Under the guidance of the guide rod 357 and the guide hole 3561, the support plate 3212 can drive the support plate 3211 to rise and fall, so as to improve the height adjustment accuracy of the square silicon rod A.

[0063] Preferably, in order to improve the lifting stability and support strength of the support plate seat 3212 and the support plate 3211, two third push blocks 352 are preferably arranged at intervals along the first horizontal direction. The two third push blocks 352 are fixedly connected to the connecting block 355, and two rollers 351 are arranged at intervals along the first horizontal direction at the bottom of the support plate seat 3212. The rollers 351 and the third push blocks 352 are arranged in a one-to-one correspondence.

[0064] Preferably, the third telescopic drive component 353 includes a third motor 3531, a third lead screw 3532, and a third nut 3533.

[0065] The main body of the third motor 3531 is fixed on the support base 3213. The drive end of the third motor 3531 is connected to the third lead screw 3532 extending along the first horizontal direction. The third nut 3533 is sleeved on the third lead screw 3532 and fixedly connected to the connecting block 355.

[0066] The third motor 3531 is used to drive the third lead screw 3532 to rotate. The third nut 3533 rotates along the third lead screw 3532 and drives the connecting block 355 to move the third push block 352 along the first horizontal direction.

[0067] The first telescopic drive member 333, the second telescopic drive member 342, and the third telescopic drive member 353 transmit power through the lead screw 111, which ensures the support strength and thus the support strength and clamping strength of the silicon rod A.

[0068] Based on the above configuration, the inclined plane mechanism composed of the third push block 352 and the roller 351 can convert the precise horizontal movement displacement of the third telescopic drive member 353 into a vertical movement displacement, so as to fine-tune the overall height of the silicon rod A and lock it firmly in the target position after adjustment. At the same time, the cooperation between the third telescopic drive member 353 and the inclined plane mechanism can reduce the volume of the lifting assembly 35.

[0069] Furthermore, the silicon rod loading and unloading slide 3 also includes a material platform base 324, a clamping plate opening and closing drive component 361, a clamping plate slide rail 362, and a synchronous rack and synchronous gear.

[0070] The clamp slide rail 362 extends along the first direction and is disposed on the top of the material platform 324. The first adjustment seat 3222 and the second adjustment seat 3232 are both slidably disposed on the clamp slide rail 362 via sliders. The main body of the clamp opening and closing drive component 361 is fixed on the material platform 324, and the drive end is connected to one of the first adjustment seat 3222 and the second adjustment seat 3232. Synchronous racks are fixedly connected to the first adjustment seat 3222 and the second adjustment seat 3232, and the two synchronous racks mesh with synchronous gears.

[0071] The clamping plate opening and closing drive 361 is used to drive the connected adjustment seat to move along the first direction. Under the meshing transmission of the synchronous gear and the synchronous rack, it drives the other adjustment seat to move along the first direction, thereby causing the first adjustment seat 3222 and the second adjustment seat 3232 to move closer to each other or further away from each other synchronously, and driving the two clamping plates to move closer to each other or further away from each other synchronously, so as to improve the clamping accuracy.

[0072] Specifically, the support base 3213 of the support platform 321 is fixed on the material platform base 324.

[0073] Optionally, the clamp opening and closing drive component 361 is a cylinder.

[0074] It should be emphasized that, based on the above-mentioned arrangement of the material table 32, the material table 32 can have multiple functions such as supporting and clamping the square silicon rod A, adjusting the horizontal angle, vertical angle and height position of the square silicon rod A, improving the correspondence accuracy between the square silicon rod A and the grinding mechanism 2, and minimizing the overall volume of the material table 32 based on the ingenious arrangement of each component.

[0075] Example 2 Based on Embodiment 1, this utility model embodiment also provides a multi-station square silicon rod A grinding machine device, which includes the square silicon rod loading and unloading slide of Embodiment 1, and also includes a base 1, multiple grinding mechanisms 2 and slide rails 11.

[0076] The base 1 has its length along a second horizontal direction and its width along a first horizontal direction. Multiple grinding mechanisms 2 are spaced apart on the base 1 along the second horizontal direction for grinding the sides and edge edges of the square silicon rod A. A slide rail 11 extends along the second horizontal direction on the base 1, and the slide rail 11 and the grinding mechanisms 2 are spaced apart along the first horizontal direction. The square silicon rod loading / unloading slide 3 is slidably mounted on the slide rail 11 and can move along the slide rail 11 to correspond to any of the grinding mechanisms 2 for loading / unloading the square silicon rod A.

[0077] When the square silicon rod loading and unloading slide 3 is located at the loading position, the square silicon rod loading and unloading slide 3 is located at the first end of the length direction of the base 1, and can support the square silicon rod A to be ground.

[0078] When the square silicon rod loading and unloading slide 3 is located in the processing position, the square silicon rod loading and unloading slide 3 corresponds to any of the grinding mechanisms 2, and is used to transfer the square silicon rod A to be ground to any of the grinding mechanisms 2 or to receive the square silicon rod A after being ground by any of the grinding mechanisms 2.

[0079] When the square silicon rod loading and unloading slide 3 is in the unloading position, the square silicon rod loading and unloading slide 3 is located at the second end of the length direction of the base 1, and is used to unload the ground square silicon rod A.

[0080] Based on the above configuration, this multi-station square silicon rod A grinding machine has the following advantages: The overall footprint is reduced: multiple grinding mechanisms 2 are arranged in a row at intervals, and a set of square silicon rod loading and unloading slides 3 is used to load and unload multiple grinding mechanisms 2, so as to reduce the overall length and the footprint.

[0081] Improve grinding efficiency: Multiple grinding mechanisms 2 can grind multiple square silicon rods A simultaneously.

[0082] Furthermore, the square silicon rod loading and unloading slide 3 is used to receive horizontally oriented square silicon rods A.

[0083] The grinding mechanism 2 includes two grinding wheels 21 and a clamp 22: Two grinding wheels 21 are arranged opposite each other along a second horizontal direction. Each grinding wheel 21 is equipped with a horizontally arranged, nested coarse and fine grinding spindle 211. The nested coarse and fine grinding spindle 211 is used to grind the sides and edge of the square silicon rod A. The nested coarse and fine grinding head integrates a coarse grinding head 2112 and a fine grinding head 2113, enabling sequential coarse and fine grinding of the square silicon rod A. The grinding wheels 21 and the square silicon rod loading / unloading slides 3 are arranged at intervals along the first horizontal direction. The clamp 22 is located above the grinding wheels 21 and can move along the first horizontal direction. The clamp 22 includes two jaws 221 that can move towards or away from each other along the first horizontal direction to clamp or release both ends of the square silicon rod A.

[0084] The two grippers 221 can move along the first horizontal direction between the grinding mold 21 and the square silicon rod loading / unloading slide 3 located at the processing position to receive the square silicon rod A to be ground or to transfer the ground square silicon rod A. The specific working principle is as follows: The two grippers 221 can clamp the two ends of the square silicon rod A to be ground, which is held by the square silicon rod loading and unloading slide 3 located at the processing position, and drive the clamped square silicon rod A to move between the two coarse and fine integrated nested spindles 211 along the first horizontal direction to grind the side and side edges of the square silicon rod A; or, the two grippers 221 can drive the clamped ground square silicon rod A to move along the first horizontal direction to the square silicon rod loading and unloading slide 3 located at the processing position, where the square silicon rod loading and unloading slide 3 receives and unloads the ground square silicon rod A.

[0085] Therefore, this application employs a nested coarse and fine grinding spindle 211 to simultaneously perform coarse and fine grinding operations, thereby improving grinding efficiency and reducing spindle length and device size. Simultaneously, the grinding wheel 21 is arranged as two horizontally opposite nested coarse and fine grinding spindles 211, with a clamp 22 holding a horizontally oriented square silicon rod A and moving it along its axial direction (i.e., along the first horizontal direction) between the two spindles for grinding, forming a horizontal grinding mechanism 2. This reduces the overall height of the grinding mechanism 2 and decreases its footprint, making it suitable for grinding relatively long square silicon rods A in a limited space. Furthermore, the grinding wheel 21 and the square silicon rod loading / unloading slides 3 are arranged at intervals along the first horizontal direction to reduce the overall width and floor space.

[0086] Specifically, the grinding wheel 21 also includes a frame 212, on which a coarse and fine integrated nested spindle 211 is mounted. The frame 212 is slidably mounted on a grinding wheel slide rail 28 extending along the first direction on the base 1 via a slider, so as to adjust the distance between the two grinding wheels 21, which is suitable for grinding square silicon rods A of different diameters.

[0087] Specifically, the coarse and fine integrated nested spindle 211 includes a first shaft and a second shaft 2111 arranged coaxially. The second shaft 2111 can extend and retract relative to the first shaft, and the first shaft and the second shaft 2111 can rotate synchronously. A coarse grinding head 2112 and a fine grinding head 2113 are provided at one end of the first shaft and the second shaft 2111.

[0088] During operation, the first or second shaft 2111 first drives the set rough grinding head 2112 to extend and perform rough grinding on the four sides and four edge edges of the silicon rod A. After the rough grinding is completed, the first or second shaft 2111 drives the set rough grinding head 2112 to retract and drives the fine grinding head 2113 to extend and perform fine grinding on the four sides and four corners of the silicon rod A.

[0089] It should be noted that the specific driving principles of the first axis and the second axis 2111 in the coarse and fine integrated nested spindle 211 can be found in CN219189810U.

[0090] Furthermore, to ensure the grinding accuracy of the grinding wheel 21, the grinding wheel 21 also includes a first probe 213 mounted on the frame 212. The first probe 213 is mounted on the frame for supporting the coarse and fine integrated nested spindle 211. The probe can take multiple detection points to detect the four sides and four edge edges of the square silicon rod A held by the two jaws 221 to determine the total grinding amount and the single grinding amount.

[0091] Before the rough grinding and fine grinding processes, the probe will detect the total grinding amount and the single grinding amount of the square silicon rod A. After fine grinding, the dimensions of the four sides and four edge edges of the square silicon rod A will be detected again. After passing the inspection, the square silicon rod A will be unloaded through the square silicon rod loading and unloading slide 3.

[0092] Specifically, to support the fixture 22, the grinding mechanism 2 also includes a frame 23, a first fixture slide rail 24, and a fixture slide 25.

[0093] The frame 23 is mounted above the mold 21 and fixed to the top of the base 1. The first clamping slide rail 24 extends along the width direction of the base 1 and is disposed on the frame 23. The clamping slide 25 is slidably disposed on the first clamping slide rail 24. The two grippers 221 are disposed on the clamping slide 25, which can be close to each other or far apart along the first horizontal direction.

[0094] Based on the above configuration, the working principle of the square silicon rod loading and unloading slide 3 for feeding the grinding mechanism 2 is as follows: The square silicon rod loading and unloading slide 3 moves the square silicon rod A to be ground to a location corresponding to a grinding mechanism 2. The two grippers 221 of the grinding mechanism 2 are located at both ends of the square silicon rod A held by the square silicon rod loading and unloading slide 3, and the two grippers 221 move towards each other to clamp the square silicon rod A. The clamping slide 25 moves the two grippers 221 of the clamped square silicon rod A to the grinding wheel 21 to grind the square silicon rod A.

[0095] The process of the square silicon rod loading and unloading slide 3 unloading the grinding mechanism 2 is as follows: the square silicon rod loading and unloading slide 3 without material is moved to the position corresponding to a grinding mechanism 2. The clamp slide 25 of the grinding mechanism 2 drives the two clamps 221 holding the ground square silicon rod A to move above the square silicon rod loading and unloading slide 3. The two clamps 221 move in opposite directions to release the square silicon rod A, so as to transfer the ground square silicon rod A onto the square silicon rod loading and unloading slide 3.

[0096] Preferably, in order to ensure the accuracy of the movement of the two grippers 221 along the second direction and the clamping accuracy, the clamping slide rail 24 adopts a lead screw slide rail, which has better rigidity and is not easily deformed.

[0097] Specifically, in order to achieve the clamping and releasing of the two grippers 221, this embodiment further defines: A second clamp slide rail 26 extending along the first horizontal direction is provided on the clamp slide 25, and the clamp slide 25 is slidably disposed on the second clamp slide rail 26. One of the two grippers 221 is fixed to the clamp slide 25, and the other is slidably disposed on the second clamp slide rail 26 via a slider, so that one gripper 221 is fixed to the frame 23, and the other gripper 221 can move along the first horizontal direction, realizing that the two grippers 221 move closer to each other or further away from each other.

[0098] The arrangement of two grippers 221, one fixed and one movable, reduces the number of drive sources required, simplifying control and structure, and lowering costs. The fixed gripper 221 provides a fixed reference, improving clamping accuracy. Furthermore, the fixed gripper 221 forms a rigid support structure, enhancing clamping stability.

[0099] Preferably, both the first clamp slide rail 24 and the second clamp slide rail 26 are lead screw slide rails, which have good rigidity and can stably support the clamp 22.

[0100] Furthermore, both grippers 221 are mounted on the gripper arm 27. One gripper 221 is fixed to the fixture slide 25 via the gripper arm 27, and the other gripper 221 is slidably mounted on the slider via the gripper arm 27.

[0101] The grinding mechanism 2 also includes two rotary drive components.

[0102] The main bodies of the two rotary drive components are fixed on the corresponding clamping arms 27. The drive ends of the two rotary drive components are respectively connected to the two chucks. The rotary drive components are used to drive the chucks to rotate around the horizontal axis to adjust the grinding position of the square silicon rod A.

[0103] During grinding, the two jaws 221 first move the square silicon rod A to be ground between the two spindles to grind the opposite two sides and side edges of the square silicon rod A. Then, the two jaws 221 move the square silicon rod A to one end of the two spindles, which corresponds to the slide rail 11. Then, the rotating drive unit drives the chuck to rotate the square silicon rod A 90 degrees around the axis. Then, the two jaws 221 move between the two spindles to grind the remaining opposite two sides and side edges of the square silicon rod A.

[0104] Optionally, the rotary drive is a motor.

[0105] Furthermore, to facilitate loading and unloading, this embodiment further specifies: A slide rail 11 extends from the top of the base 1 along the second horizontal direction. The square silicon rod loading and unloading slide 3 includes a slide base 31 and a loading platform 32. The loading platform base 324 of the loading platform 32 is fixed to the top of the slide base 31. The slide base 31 is slidably disposed on the slide rail 11.

[0106] In use, the slide 31 can drive the material table 32 to move along the slide rail 11 to the loading position, processing position, and unloading position. When the material table 32 moves to the loading position, the support table 321 can support the square silicon rod A, and the first clamping plate 322 and the second clamping plate 323 clamp the horizontal sides of the square silicon rod A to hold the square silicon rod A. When the material table 32 receiving the square silicon rod A to be ground moves to the position corresponding to any grinding mechanism 2, the two jaws 221 of the grinding mechanism 2 are located at both ends of the square silicon rod A received by the support table 321. The two jaws 221 move towards each other to clamp the square silicon rod A, and the first clamping plate 322 and the second clamping plate 323 release the square silicon rod A, and the two jaws 221 drive the clamped square silicon rod A away from the material table 32. When the material table 32 receiving the ground square silicon rod A moves to the unloading position, the ground square silicon rod A can be unloaded by a robot or other mechanism.

[0107] The material platform 32, through its precise structural arrangement, has a small volume and is suitable for installation on the material platform base 324 with limited dimensions.

[0108] Preferably, during the feeding process of the material table 32 to the two grippers 221, the two grippers 221, as well as the first clamping plate 322 and the second clamping plate 323, will simultaneously clamp the square silicon rod A in a short period of time. In order to avoid the slide rail 11 being deformed by force and affecting the movement accuracy of the loading and unloading mechanism 3, the slide rail 11 is preferably a lead screw slide rail, which has better rigidity and is not easily deformed, thus ensuring the positioning accuracy of the loading and unloading mechanism 3.

[0109] More preferably, if the slide rail 11 is a lead screw slide rail, the slide block 31 is threadedly connected to the lead screw 111 of the slide rail 11 and driven to move by the lead screw 111. Since the slide block 31 needs to move along the slide rail 11 to the corresponding grinding mechanism 2, the stroke groove of the lead screw 111 is relatively long. To overcome the bending deformation that may occur due to the local bearing of the weight of the material table, two auxiliary slide blocks 37 are added on both sides of the square silicon rod loading and unloading slide 3 on the slide rail 11. The two auxiliary slide blocks 37 are threadedly connected to the lead screw 111 and driven by their own motor to follow the slide block 31. The two auxiliary slide blocks 37 are used to support the lead screw 111 on both sides of the square silicon rod loading and unloading slide 3 to prevent the lead screw 111 from bending due to the local bearing of the weight of the square silicon rod loading and unloading slide 3, which would affect the accuracy and service life of the slide rail 11.

[0110] The slide block 31 and the auxiliary slide table 37 are both fitted and threaded onto the lead screw 111 of the lead screw slide rail.

[0111] Furthermore, to ensure the accuracy of the silicon rod loading and unloading slide 3 as it moves along the slide rail 11 to each position, this embodiment further specifies: A magnetic scale 12 is provided on the base 1. The length of the magnetic scale 12 covers the entire stroke of the slide rail 11. It is used to detect the position of the square silicon rod loading and unloading slide 3 in real time, so as to ensure that the square silicon rod loading and unloading slide 3 can accurately stop and align with any grinding mechanism 2.

[0112] Furthermore, in order to detect whether the horizontal angle, vertical angle and height position of the square silicon rod A placed on the square silicon rod loading and unloading slide 3 meet the requirements, this multi-station square silicon rod A grinding machine device also includes a detection structure for detecting the square silicon rod A.

[0113] The detection mechanism includes a second probe 4 and a third probe. The second probe 4 is located above the square silicon rod loading / unloading slide 3 at the loading position, and can detect whether the square silicon rod A supported by the square silicon rod loading / unloading slide 3 is tilted in the horizontal direction and whether the height is correct. The third probe is located at both ends of the square silicon rod loading / unloading slide 3 at the loading position, and can detect whether the square silicon rod A supported by the square silicon rod loading / unloading slide 3 is tilted in the vertical direction.

[0114] It should be noted that the testing datum of the testing agency is the positioning center of the grinding mechanism 2 and the clamping center of the two jaws 221.

[0115] Furthermore, the following is the loading and unloading method of this multi-station square silicon rod A grinding machine device.

[0116] The feeding method is as follows: S11, the square silicon rod loading and unloading slide 3 is located at the loading position, and the support platform 321 receives the horizontally oriented square silicon rod A to be ground.

[0117] S12. First, the horizontal adjustment component 33 adjusts the horizontal angle of the supported square silicon rod A. Then, the lifting component 35 adjusts the height of the supported square silicon rod A to the clamping height of the grinding mechanism 2, that is, the clamping height of the two jaws 221. Subsequently, the first clamping plate 322 and the second clamping plate 323 clamp the horizontal sides of the supported square silicon rod A, and the vertical adjustment component 34 adjusts the vertical angle of the supported square silicon rod A to adjust the center of both ends of the square silicon rod A to the clamping center corresponding to the two jaws 221.

[0118] S13. The square silicon rod loading and unloading slide 3 moves from the loading position to the position corresponding to any of the grinding mechanisms 2. The grinding mechanism 2 clamps the two ends of the square silicon rod A, that is, the two jaws 221 clamp the two ends of the square silicon rod A. Then, the first clamping plate 322 and the second clamping plate 323 release the horizontal sides of the square silicon rod A.

[0119] S14. The grinding mechanism 2 grinds the four sides and four edge edges of the square silicon rod A, that is, the two grippers 221 drive the gripped square silicon rod A to move along the first horizontal direction between the two grinding heads to grind the sides and edge edges of the square silicon rod A.

[0120] The feeding method is as follows: S21. The square silicon rod loading and unloading slide 3 moves to the position corresponding to any of the grinding mechanisms 2. The grinding mechanism 2 places the ground square silicon rod A on the support platform 321. That is, the two grippers 221 of the grinding mechanism 2 drive the ground square silicon rod A to move toward the square silicon rod loading and unloading slide 3 and place the square silicon rod A on the support platform 321. The first clamping plate 322 and the second clamping plate 323 clamp the horizontal sides of the supported square silicon rod A, and the two grippers 221 release the square silicon rod A.

[0121] S22, the square silicon rod loading and unloading slide 3 drives the square silicon rod A it receives to move to the unloading position.

[0122] Specifically, steps S13, S14, and S21 also include: S13. The square silicon rod loading and unloading slide 3 moves from the loading position to the position corresponding to any grinding mechanism 2. The grinding mechanism 2 clamps the two ends of the square silicon rod A it is receiving, that is, the two jaws 221 clamp the two ends of the square silicon rod A it is receiving. Then, the first clamping plate 322 and the second clamping plate 323 release the horizontal sides of the square silicon rod A it is receiving. Then, the support table 321 descends and disengages from the square silicon rod A.

[0123] S14. The two grippers 221 drive the square silicon rod A held therein to move between the two grinding tools 21 along the first horizontal direction, and the two grinding tools 21 grind the four sides and four edge edges of the square silicon rod A.

[0124] S21, the square silicon rod loading and unloading slide 3 moves to the position corresponding to any grinding mechanism 2. The two grippers 221 of the grinding mechanism 2 drive the ground square silicon rod A to move toward the square silicon rod loading and unloading slide 3 and place the square silicon rod A on the support platform 321. The two grippers 221 release the square silicon rod A. The support platform 321 drives the square silicon rod A to descend and disengage from the two grippers 221. The first clamping plate 322 and the second clamping plate 323 clamp the horizontal sides of the square silicon rod A.

[0125] It should be noted that the square silicon rod loading and unloading slide 3 that has not received the square silicon rod A can be moved to the loading position to load again, or moved to the corresponding grinding mechanism 2 to unload the ground square silicon rod A.

[0126] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications, alterations, substitutions and variations to the above embodiments within the scope of the present invention.
