[0027] In order to better explain the present invention, so as to facilitate understanding, the following Figure 1-Figure 4 The present invention is described in detail through specific implementation methods. Figure 2 The orientation is used as a reference.

[0028] Embodiment 1:

[0029] Reference Figure 1-Figure 4 An embodiment of the present invention provides a square silicon rod positioning and adjustment device, which is suitable for being clamped by a clamping manipulator on the end face in the length direction and subjected to grinding processing, and comprises a lifting platform 1, a fine-tuning lifting component 2 and a support plate 3; one end of the support plate 3 is hinged on the lifting platform 1 along the axis in the front-back direction; the body of the fine-tuning lifting component 2 is fixed on the lifting end of the lifting platform 1, and the lifting end of the fine-tuning lifting component 2 is connected to the other end of the support plate 3, so that one end of the support plate 3 can be lifted or lowered under the drive of the lifting end to adjust the angle with the horizontal direction.

[0030] In this embodiment, during the grinding process of the square silicon rod, when it is detected that the grinding allowance at the front end or rear end of the square silicon rod is insufficient, the square silicon rod is placed back on the support plate 3, and the lifting end of the fine-tuning lifting assembly 2 is controlled to drive the support plate 3 to rise or fall by the calculated distance value, so that the square silicon rod has sufficient grinding allowance when it is clamped and ground again by the fixture, and the processing accuracy of the square silicon rod during grinding is improved, thereby meeting the grinding requirements. That is, the center of the square silicon rod has a better coincidence with the center of rotation of the fixture, so that not only the processing accuracy is high, the tolerance of the machine tool to the front-order accuracy of the square silicon rod is increased, and the axis of the square silicon rod and the axis of the clamp during grinding can coincide, and the processing efficiency is also improved.

[0031] Specifically, the lifting platform 1 provides a stable support platform. The body of the fine-tuning lifting assembly 2 is fixed on the lifting platform 1, and the lifting end is connected to the other end of the support plate 3. By accurately controlling the lifting distance of the lifting end, the angle of the support plate 3 can be fine-tuned. Driven by the fine-tuning lifting assembly 2, the support plate 3 can be lifted or lowered, thereby adjusting the angle with the horizontal direction.

[0032] During the grinding process of the square silicon rod, if it is detected that the grinding allowance at the front or rear end of the square silicon rod is insufficient, the following operations need to be performed:

[0033] Replacing the square silicon rod: Replacing the square silicon rod on the support plate 3 , and ensuring that the square silicon rod is in close contact with the support plate 3 .

[0034] Calculate the adjustment distance: According to the insufficient grinding allowance of the square silicon rod, calculate the distance value that needs to be adjusted. This distance value is obtained through precise mathematical calculation to ensure that the square silicon rod has sufficient grinding allowance when it is clamped and ground again.

[0035] Control the fine-tuning lifting component 2: by controlling the lifting end of the fine-tuning lifting component 2, the support plate 3 is driven to rise or fall to the calculated distance value.

[0036] Re-clamping and grinding: After the angle adjustment of the support plate 3 is completed, the square silicon rod is clamped again with the fixture and ground. Due to the adjustment of the angle of the support plate 3, the center of the square silicon rod and the rotation center of the fixture are better coincident, thereby improving the processing accuracy and processing efficiency.

[0037] In summary, this square silicon rod positioning and adjustment device has significant application advantages in the grinding process of square silicon rods. It not only improves the processing accuracy and efficiency, but also increases the tolerance of the machine tool to the pre-process accuracy of the square silicon rods.

[0038] Embodiment 2:

[0039] Reference Figure 1-Figure 4 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0040] The fine-tuning lifting assembly 2 includes a screw rod 21, a nut 22, a first top block 23 and a second top block 24; the screw rod 21 is connected to the lifting platform 1 by rotating along its own axis, the nut 22 is threadedly connected to the screw rod 21, and the first top block 23 is fixed on the support plate 3; the second top block 24 is slidably supported on the support plate 3 or the lifting platform 1 along the axis of the screw rod 21; the first top block 23 and the second top block 24 respectively have a first inclined surface and a second inclined surface abutting against each other;

[0041] The plane perpendicular to the first inclined plane and the second inclined plane is the first plane. The first plane is parallel to the axis of the screw 21, or passes through the axis of the screw 21, so as to ensure that the operation process of the screw 21 does not interfere with the mutual lifting action of the first inclined plane and the second inclined plane, thereby ensuring the operation stability and reliability of the fine-tuning lifting assembly.

[0042] The fine-tuning lifting assembly 2 further includes a rotary driving member 26 drivingly connected to the screw rod 21 .

[0043] In this embodiment, the fine-tuning lifting assembly 2 converts the rotary motion of the screw 21 into the sliding motion of the first top block 23, and under the mutual contact between the first inclined surface and the second inclined surface, it is converted into the lifting motion of the second top block 24, so that the second top block 24 can drive the support plate 3 to swing. Through this action conversion, the stability of the support plate 3 when swinging can be guaranteed, and it is also conducive to improving the swing accuracy of the support plate 3. In addition, one end of the support plate 3 is hinged on the lifting platform 1, that is, the support plate 3 and the lifting platform 1 have only this one active connection point, thereby improving the assembly convenience of the support plate 3, and one connection point is also conducive to further improving the control accuracy of the support plate 3.

[0044] Specifically, the angle of the first bevel and the second bevel can be set at 30°-60° to ensure the matching stability of the first bevel and the second bevel, and can also effectively control the driving force offset by the interaction of the component forces when the first bevel and the second bevel are matched, thereby keeping the load of the rotary drive member 26 within a reasonable range.

[0045] More specifically, the rotary drive member 26 is a servo motor, which is precisely controlled by a controller.

[0046] The fine-tuning lifting assembly 2 also includes a connecting block 25 fixed on the lifting platform 1, and a sliding groove is provided on the connecting block 25. The second top block 24 is slidably connected in the sliding groove along the axial direction of the screw rod 21; the connecting block 25 is also provided with a clearance opening that is connected to the sliding groove and extends along the axial direction of the screw rod 21. A connecting head 220 extends from the nut 22, and the connecting head 220 is connected to the second top block 24 after passing through the clearance opening.

[0047] In this embodiment, the connecting block 25 is used to slidingly support the second top block 24, and at the same time adapts to the connection condition between the nut 22 and the second top block 24, thereby improving the layout convenience of the fine-tuning lifting assembly 2, and can also ensure the sliding stability of the second top block 24, thereby ensuring the fine-tuning lifting assembly 2 for the height control accuracy of the support plate 3.

[0048] Embodiment 3:

[0049] Reference Figure 1-Figure 4 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0050] The lifting platform 1 includes a base 11, a frame 12, a lifting plate 13 and a contact portion 14. The frame 12 is vertically slidably connected to the base 11, the lifting plate 13 is horizontally slidably connected to the base 11, and the contact portion 14 is fixedly connected to the frame 12; a third inclined surface is formed on the lifting plate 13, the third inclined surface faces the contact portion 14, and the angle of the third inclined surface can be set at 30°-60°; wherein the contact portion 14 is kept in contact with the third inclined surface, so that when the lifting plate 13 slides horizontally, the height of the position of the abutting contact portion 14 on the third inclined surface is changed, thereby changing the height of the frame 12.

[0051] In this embodiment, the base 11 is the basic part of the lifting platform 1, which is fixed on the ground and provides support for the entire lifting platform 1. The frame 12 is the supporting structure of the lifting platform 1, and it is vertically slidably connected to the base 11. The height of the frame 12 can change with the lifting of the lifting platform 1. The lifting plate 13 is a component that can slide horizontally on the base 11, and the height of the frame 12 can be changed by sliding. The contact portion 14 is in contact with the third inclined surface on the lifting plate 13. When the lifting plate 13 slides, the contact portion 14 moves along the third inclined surface, thereby changing the height of the frame 12. The third inclined surface is an inclined surface formed on the lifting plate 13, which faces the contact portion 14. The design of the third inclined surface makes it possible for the position of the contact portion 14 on the lifting plate 13 to change when the lifting plate 13 slides horizontally, thereby changing the height of the frame 12.

[0052] When the lifting plate 13 slides horizontally on the base 11, the contact portion 14 moves along the third inclined surface due to the presence of the third inclined surface. The movement of the contact portion 14 on the third inclined surface causes the height of the frame 12 relative to the base 11 to change. Specifically, when the lifting plate 13 slides in one direction, the contact portion 14 moves upward along the third inclined surface, thereby pushing the frame 12 to rise; conversely, when the lifting plate 13 slides in another direction, the contact portion 14 moves downward along the third inclined surface, causing the frame 12 to fall.

[0053] In this way, the lifting platform 1 can achieve the lifting function in the vertical direction without using a complex mechanical structure or hydraulic system.

[0054] The design of the lifting platform 1 has the advantages of simple structure, convenient operation, easy maintenance, etc. At the same time, through this action conversion, the stability of the frame 12 during height adjustment can be ensured, which is also conducive to improving the height adjustment accuracy of the frame 12.

[0055] Specifically, the contact portion 14 can be configured as a roller hinged on the frame body 12 along the front-rear direction, the lifting plate 13 can be configured to slide horizontally, and the connecting plate is driven by a servo drive.

[0056] Embodiment 4:

[0057] Reference Figure 1-Figure 4 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0058] The lifting platform 1 also includes a connecting assembly 15, which includes a connecting rod 151, an elastic member 152 and a connecting sleeve 153; one end of the connecting rod 151 is fixed to the base 11, the connecting sleeve 153 is fixed to the frame 12, the connecting sleeve 153 and the connecting rod 151 are vertically slidably connected, and the two ends of the elastic member 152 are respectively connected to the connecting rod 151 and the connecting sleeve 153, and when the frame 12 rises, force is accumulated to provide elastic potential energy to move the connecting rod 151 and the connecting sleeve 153 away from each other.

[0059] In this embodiment, under the elastic force of the elastic member 152 , the contact portion 14 on the frame 12 will keep contacting the third inclined surface to ensure the stability and lifting accuracy of the contact portion 14 when the third inclined surface drives the contact portion 14 to rise and fall, thereby ensuring the lifting stability and lifting accuracy of the lifting platform 1 .

[0060] Specifically, one end of the connecting rod 151 is fixed on the base 11, such as being connected to the base 11 by a threaded connection, providing a solid support for the entire structure of the lifting platform 1. The connecting sleeve 153 is fixed on the frame 12, and forms a tight vertical sliding connection with the connecting rod 151. This design allows the frame 12 to move freely in the vertical direction while ensuring its stability during movement.

[0061] The elastic member 152 can be set as a spring, the upper end of the spring abuts against the upper end of the connecting rod 151, and the lower end of the spring abuts against the lower end of the connecting sleeve 153. When the frame 12 rises, the spring is compressed and stored, so that the contact portion 14 on the frame 12 can be tightly abutted against the third inclined surface of the lifting plate 13. This close contact not only enhances the stability during the lifting process, but also greatly improves the lifting accuracy. Because only when the contact portion 14 maintains stable contact with the third inclined surface, the third inclined surface can accurately drive the contact portion 14 to perform lifting and lowering movements, thereby ensuring the overall lifting stability and lifting accuracy of the lifting platform 1.

[0062] In summary, the introduction of the connecting assembly 15 adds a solid guarantee to the design of the lifting platform 1. It not only improves the stability and accuracy of the lifting process, but also lays a solid foundation for the long-term stable operation of the lifting platform 1.

[0063] The lifting plate 13 and the contact portion 14 are arranged as two groups on both sides of the connecting assembly 15 to improve the force balance of the lifting platform 1 , thereby further improving the lifting stability and accuracy of the lifting platform 1 .

[0064] Embodiment 5:

[0065] Reference Figure 1-Figure 4 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0066] The frame 12 includes a front side plate, a rear side plate 121 and a horizontal plate 122 connecting the two, and the connecting sleeve 153 is fixed on the horizontal plate 122; the screw 21 is rotatably connected to the front side plate and the rear side plate 121, and the top surfaces of the front side plate and the rear side plate 121 form a bearing surface. When the fine-tuning lifting assembly 2 makes the pallet 3 descend to the extreme position, the bearing surface supports the pallet 3.

[0067] In this embodiment, the components including the front side plate, the rear side plate 121 and the horizontal plate 122 connecting the two together constitute a stable frame structure, which not only enhances the overall strength of the frame 12, but also provides it with sufficient stability and rigidity to ensure stability during the lifting process.

[0068] At the same time, the front side plate and the rear side plate 121 with a spacing therebetween make it easier to arrange the fine-tuning lifting assembly 2 including the screw rod 21, thereby improving the convenience of assembly and maintenance thereof.

[0069] The top surfaces of the front side plate and the rear side plate 121 together form a bearing surface. When the fine-tuning lifting assembly 2 causes the support plate 3 to descend to the limit position, the bearing surface will stably support the support plate 3 to prevent it from continuing to descend and provide solid support for it. In this way, even if the fine-tuning lifting assembly 2 is realized, it can ensure that the support plate 3 can always be effectively supported, thereby improving the reliability of the use of the square silicon rod positioning and adjustment device.

[0070] Embodiment 6:

[0071] Reference Figure 1-Figure 4 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0072] The lifting platform 1 further includes an outer cover 16 and a bottom shell 17 . The bottom shell 17 is connected to the outside of the base 11 . The outer cover 16 is connected to the outside of the frame 12 . Both the bottom shell 17 and the outer cover 16 extend vertically, and the outer cover 16 is disposed on the outside of the bottom shell 17 .

[0073] In this embodiment, the bottom shell 17 is connected to the outside of the base 11 as the bottom protection structure of the lifting platform 1, which can effectively prevent external factors such as dust and debris from interfering with and damaging the internal mechanical structure of the lifting platform 1. The outer cover 16 is the external packaging structure of the lifting platform 1, which can effectively protect the frame 12 and various components thereon from erosion and damage by the external environment.

[0074] Both the bottom shell 17 and the outer cover 16 are designed to extend vertically. The outer cover 16 is arranged on the outside of the bottom shell 17, which further enhances the overall protection effect of the lifting platform 1. In addition, during the entire lifting process of the lifting platform 1, the outer cover 16 remains arranged on the outside of the bottom shell 17, thereby improving the protection effect of the outer cover 16 and the bottom shell 17 on the lifting platform 1.

[0075] Embodiment 7:

[0076] Figure 1-Figure 4 In addition to providing a square silicon rod height adjustment method, the embodiment of the present invention is applied to the square silicon rod positioning and adjustment device according to any one of claims 1 to 9, and the adjustment method includes:

[0077] S1: Place the standard jig on the pallet 3, and raise the pallet 3 to a first height by means of the lifting platform 1, and record the top surface height of the standard jig as H0;

[0078] S2: Remove the standard fixture and reset the lifting platform 1;

[0079] S3: placing the square silicon rod on the support plate 3, and raising the support plate 3 to a first height by means of the lifting platform 1, and recording the top surface height of the square silicon rod as H1;

[0080] S4: Adjust the height of the lifting platform 1 to H1-H0;

[0081] S5: clamping the square silicon rod by a grinding fixture and transferring it to a grinding device;

[0082] S6: Measure the minimum grinding allowance of the square silicon rod along the length direction of the square silicon rod;

[0083] S7: When the minimum grinding allowance of the square silicon rod is insufficient, the square silicon rod is placed back on the support plate 3, and the angle of the support plate 3 is adjusted by fine-tuning the lifting component 2 to balance the grinding allowance of the square silicon rod.

[0084] This square silicon rod height adjustment method is designed to accurately adjust the height and angle of the square silicon rod to ensure its accuracy and balanced grinding allowance during the grinding process, as follows:

[0085] Step S1: Standard fixture positioning and height recording

[0086] First, a standard jig is placed on the support plate 3. The standard jig has a known, uniform size and shape and is used as a reference for height adjustment.

[0087] By operating the lifting platform 1, the support plate 3 and the standard jig thereon are raised to a preset first height. This height is preset according to the operation requirements to ensure that the standard jig and the square silicon rod can be at the same height position for comparison in the subsequent steps.

[0088] The top surface height of the standard fixture is recorded as H0. This height value will be used as the basis for subsequent adjustment of the height of the square silicon rod.

[0089] At this time, when the clamp clamps square silicon rods of the same size and height, it will clamp at the predetermined center axis position of the square silicon rod, which can ensure the clamping stability and clamping accuracy of the square silicon rod.

[0090] Step S2: Removal of standard fixture and resetting of lifting platform 1

[0091] The standard jig is removed so as to place the square silicon rod on the support plate 3 .

[0092] The lifting platform 1 is reset, that is, it is lowered to the initial position in preparation for placing the square silicon rods.

[0093] Step S3: Placement of square silicon rods and height recording

[0094] Place the square silicon rod on the support plate 3 to ensure that the square silicon rod is stable and in good contact with the support plate 3 .

[0095] The support plate 3 is raised to the first height again by the lifting platform 1, and at this time the square silicon rods will also reach the same height.

[0096] The top surface height of the square silicon rod is recorded as H1. This height value reflects the height difference of the square silicon rod relative to the standard fixture.

[0097] Step S4: Height adjustment of lifting platform 1

[0098] Based on the height values ​​H0 and H1 recorded in steps S1 and S3, the height difference H1-H0 is calculated.

[0099] By adjusting the height of the lifting platform 1, the top surface height of the square silicon rod is consistent with the top surface height of the standard fixture, that is, the height difference H1-H0 is eliminated, specifically, the lifting platform 1 rises or falls by H1-H0. In this way, the actual center axis position of the square silicon rod still coincides with the standard center axis position when the fixture clamps the square silicon rod.

[0100] Step S5: Square silicon rod clamping and transportation

[0101] Use a grinding fixture to clamp the adjusted square silicon rod.

[0102] The square silicon rod is transferred to the grinding device and prepared for grinding.

[0103] Step S6: Measurement of grinding allowance of square silicon rod

[0104] The grinding allowance of the square silicon rod is measured on the grinding device to ensure that the square silicon rod can reach the expected size and shape during the grinding process.

[0105] Specifically, nine measuring points may be evenly taken along the length direction of the square silicon rod, and the grinding allowances of the nine measuring points may be measured to ensure the measurement accuracy.

[0106] The grinding allowance measurement work can be performed after a stage of grinding is performed, or before grinding is performed, preferably before grinding is performed.

[0107] Step S7: Adjust the angle of the square silicon rod and balance the grinding allowance

[0108] If the grinding allowance at the front or back end of the square silicon rod is found to be insufficient during the measurement process, this may be caused by the unevenness of the square silicon rod itself or errors in the grinding process.

[0109] At this time, the square silicon rod is placed back on the support plate 3. The angle of the support plate 3 is adjusted by fine-tuning the lifting assembly 2, and then the height difference between the front and rear ends of the square silicon rod is fine-tuned, so that the grinding allowance of the square silicon rod can be balanced, so that it can achieve a more uniform and consistent effect during the grinding process.

[0110] This method combines the functions of height adjustment and angle fine-tuning to ensure the accuracy and efficiency of the square silicon rod during grinding. Through this method, the processing quality and production efficiency of the square silicon rod can be greatly improved.
