Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic technology, and in particular to a positioning tool for cutting silicon rod edge blocks. Background Technology
[0002] Cylindrical silicon rods are solid, high-purity cylinders with a specific crystal structure, formed from purified polycrystalline silicon raw materials through a specific crystal growth process. Silicon rods themselves cannot be used directly to manufacture batteries; they need to be cut into very thin circular or square wafers, i.e., silicon wafers, using a wire cutting process.
[0003] When a cylindrical silicon rod is cut into square sheets, it is generally necessary to first cut off a portion of material from the silicon rod. This portion of material is usually called a silicon rod edge piece, and the shape of the silicon rod edge piece is as follows: Figure 1 As shown, one side is an arc surface, the surface opposite the arc surface is a side plane, and the other two end faces are end planes.
[0004] Discarding silicon rod scraps directly as waste would be wasteful. Therefore, in existing technology, silicon rod scraps are typically cut into rectangular blocks for reuse.
[0005] In the existing technology, when cutting the edge blocks of silicon rods, there is a lack of positioning for the edge blocks. This causes the edge blocks to easily shift when using diamond wire cutting, resulting in irregular cuts. Utility Model Content
[0006] The purpose of this utility model is to provide a positioning fixture for cutting silicon rod edge blocks, which can position the silicon rod edge blocks to ensure the cutting accuracy of the silicon rod edge blocks.
[0007] To achieve this objective, the present invention adopts the following technical solution:
[0008] A positioning fixture for cutting silicon rod edge pieces includes:
[0009] Base;
[0010] The first positioning component is used to position the silicon rod edge block when cutting the sharp corner of the end of the silicon rod edge block. It includes a first positioning post and a first clamping member. The first positioning post and the first clamping member are arranged adjacent to each other on the base along a first horizontal direction. The side of the first positioning post is configured to abut against the side plane of the silicon rod edge block, and the first clamping member is configured to clamp the arc surface of the silicon rod edge block.
[0011] The second positioning component is used to position the silicon rod edge block when cutting the side arc block of the silicon rod edge block. It is set on the base and can simultaneously limit the silicon rod edge block in the first horizontal direction and the second horizontal direction, wherein the second horizontal direction is perpendicular to the first horizontal direction.
[0012] As an optional embodiment of the positioning fixture for cutting silicon rod edge blocks, the second positioning component includes a second positioning post and two second clamping members. The second positioning post is disposed on the base and adjacent to the second clamping members along the second horizontal direction. The side of the second positioning post is configured to abut against the side plane to limit the silicon rod edge block in the second horizontal direction. The two second clamping members are disposed adjacent to each other on the base along the first horizontal direction, and the two second clamping members can respectively abut against the two end planes of the silicon rod edge block.
[0013] As an optional embodiment of the positioning fixture for cutting the edge strip of the aforementioned silicon rod, the second clamping member includes:
[0014] The second clamping component body is disposed on the base;
[0015] The second clamping member head is adjustablely positioned on the second clamping member body, and the second clamping member head can abut against the end plane.
[0016] As an optional embodiment of the positioning fixture for cutting silicon rod edge blocks, the second positioning component includes a second positioning post and a third clamping member. The second positioning post is disposed on the base, and the side of the second positioning post is configured to abut against the side plane to limit the silicon rod edge block in the second horizontal direction. The third clamping member is disposed on the base and can press against the end cutting surface of the silicon rod edge block in the vertical direction.
[0017] As an optional embodiment of the positioning fixture for cutting the edge of the silicon rod, the third clamping member is disposed at the top of the second positioning post.
[0018] As an optional embodiment of the positioning fixture for cutting silicon rod edge blocks, the second positioning component includes two second positioning posts, which are arranged adjacent to each other on the base along the first horizontal direction. The side of the second positioning post is configured to abut against the side plane to limit the silicon rod edge block along the second horizontal direction.
[0019] As an optional embodiment of the positioning fixture for cutting silicon rod edge blocks, the positioning fixture for cutting silicon rod edge blocks further includes a third positioning component. The third positioning component includes a movable clamping member. The movable clamping member is adjustablely positioned on the base along the first horizontal direction. The movable clamping member can abut against the end cutting surface of the silicon rod edge block along the second horizontal direction.
[0020] As an optional embodiment of the positioning fixture for cutting the edge of the aforementioned silicon rod, the third positioning component further includes:
[0021] A fixing seat is fixedly disposed on the base, and the fixing seat is provided with an adjustment hole that extends through the first horizontal direction;
[0022] The movable component is adjustablely positioned in the adjustment hole along the first horizontal direction, and the movable clamping component is located at one end of the movable component.
[0023] As an optional embodiment of the positioning fixture for cutting the edge of the silicon rod, the third positioning component further includes a movable locking member, one end of which is threaded through the fixed base and located in the adjustment hole and can abut or separate from the movable member.
[0024] As an optional embodiment of the positioning fixture for cutting silicon rod edge blocks, the first positioning component further includes a third positioning post. The third positioning post is disposed on the base and is adjacent to the first positioning post along the second horizontal direction. The side of the third positioning post is configured to abut against the side plane of the silicon rod edge block. A fourth clamping member is provided on the third positioning post, and the fourth clamping member can abut against the end plane of the silicon rod edge block in the vertical direction.
[0025] The beneficial effects of this utility model are:
[0026] The positioning fixture for cutting silicon rod edge blocks proposed in this utility model can position silicon rod edge blocks in different positions, ensuring that the silicon rod edge blocks will not shift when the diamond wire cuts the silicon rod edge blocks, thus ensuring the accuracy of the cutting of the silicon rod edge blocks, and ultimately ensuring that the cut silicon rod edge blocks have a regular shape and meet the design requirements.
[0027] Specifically, when performing the step of cutting off the sharp corners at the ends, the silicon rod edge piece is placed on the base, with one end plane of the silicon rod edge piece aligned with the upper surface of the base, and the side plane of the silicon rod edge piece abutting against the side of the first positioning post. Simultaneously, the position of the silicon rod edge piece is adjusted to a preset position, and then the first clamping member is used to clamp the arc surface of the silicon rod edge piece. At this time, the positioning fixture for cutting the silicon rod edge piece limits its movement along the first horizontal direction, restricting its movement in that direction. Simultaneously, under the clamping action of the first positioning post and the first clamping member, the silicon rod edge piece cannot move along the second horizontal direction. Then, the diamond wire is controlled to cut off one of the sharp corners at the ends according to the preset path.
[0028] Understandably, when cutting off the other end sharp corner, the silicon rod edge block is rotated along the second horizontal direction, and the above positioning method is used to control the diamond wire to cut off the other end sharp corner.
[0029] Specifically, when performing the step of cutting off the side arc block, the second positioning component is used to position the silicon rod edge block. At this time, since the cutting path of the diamond wire remains unchanged, it is necessary to adjust the position of the silicon rod edge block so that the edge of the side arc block is located on the cutting path of the diamond wire. Therefore, the first positioning component cannot meet the positioning requirements of the silicon rod edge block at this time. At this time, the second positioning component is used to position the silicon rod edge block in the first horizontal direction and the second horizontal direction at the same time so that the diamond wire can complete the cutting of the side arc block.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0049] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0052] Example 1
[0053] See Figure 1 The structure of a common silicon rod edge block 10 is as follows: Figure 1 As shown. One side of the silicon rod edge block 10 is an arc surface 102, the surface opposite to the arc surface 102 is a side plane 101, and the other two opposite surfaces are called end planes 103.
[0054] Further, see Figure 2 To avoid wasting raw materials, the silicon rod edge pieces 10 generally need to be cut, and the irregularly shaped silicon rod edge pieces 10 are processed into cuboid blocks. Specifically, in Figure 2 In this process, the surface formed by the first and second cuts is called the end cut surface 104, and the surface formed by the third cut is called the side cut surface 105.
[0055] It should be noted that, in Figure 2 In the diagram, the first cut and the second cut are views from the same perspective; both are views taken from a perspective perpendicular to the end plane 103; the third cut has a different perspective from the second cut, and is a view taken from a perspective perpendicular to the end cutting surface 104.
[0056] It should be noted that in this embodiment, the first cut, second cut, and third cut are not restrictions on the cutting order, but rather distinctions in the cutting method. That is, the first cut is the step of cutting off the first end sharp corner; the second cut is the step of cutting off the second end sharp corner (the first and second cuts are essentially the same, both aimed at cutting off the end sharp corner 107); and the third cut is the step of cutting off the side arc block 106. In actual cutting, the order of the first cut, second cut, and third cut can be followed, or the order of the first cut, third cut, and second cut, or the order of the third cut, first cut, and second cut, depending on the need. No further restrictions are imposed here.
[0057] Specifically, see Figures 3-10 In order to position the silicon rod edge block 10 when cutting it, this embodiment provides a positioning fixture for cutting the silicon rod edge block.
[0058] Specifically, see Figure 3 and Figure 4 In this embodiment, the positioning fixture for cutting silicon rod edge blocks includes a base 1, a first positioning component 2, and a second positioning component 3.
[0059] It should be noted that, Figure 3 A top-down view of the silicon rod edge block being installed in the positioning fixture for cutting the silicon rod edge block during the first cut.
[0060] The first positioning component 2 is used to position the silicon rod edge block 10 when cutting the end sharp corner 107 of the silicon rod edge block 10.
[0061] The second positioning component 3 is used to position the silicon rod edge block 10 when cutting the side arc block 106 of the silicon rod edge block 10.
[0062] The first positioning component 2 includes a first positioning post 21 and a first clamping member 22. The first positioning post 21 and the first clamping member 22 are arranged adjacent to each other on the base 1 along the first horizontal direction. The side of the first positioning post 21 is configured to abut against the side plane 101 of the silicon rod edge block 10, and the first clamping member 22 is configured to clamp the arc surface 102 of the silicon rod edge block 10.
[0063] The second positioning component 3 is disposed on the base 1 and can simultaneously limit the silicon rod edge block 10 in the first horizontal direction and the second horizontal direction, wherein the second horizontal direction is perpendicular to the first horizontal direction.
[0064] The positioning fixture for cutting silicon rod edge blocks provided in this embodiment can position silicon rod edge blocks 10 at different positions, ensuring that the silicon rod edge blocks 10 will not shift when the diamond wire cuts the silicon rod edge blocks 10, ensuring the accuracy of cutting the silicon rod edge blocks 10, and ultimately ensuring that the cut silicon rod edge blocks have a regular shape and meet the design requirements.
[0065] Specifically, when performing the step of cutting off the sharp corner 107 (such as the first cut or the second cut), the silicon rod edge piece 10 is placed on the base 1, and one end plane 103 of the silicon rod edge piece 10 is attached to the upper surface of the base 1. The side plane 101 of the silicon rod edge piece 10 is abutted against the side of the first positioning post 21. At the same time, the position of the silicon rod edge piece 10 is adjusted to the preset position. Then, the first clamping member 22 is used to clamp the arc surface 102 of the silicon rod edge piece 10. At this time, the positioning fixture for cutting the silicon rod edge piece limits the movement of the silicon rod edge piece 10 in the first horizontal direction, restricting its movement. At the same time, under the clamping action of the first positioning post 21 and the first clamping member 22, the silicon rod edge piece 10 cannot move in the second horizontal direction. At this time, the diamond wire is controlled to cut off one of the sharp corners 107 according to the preset path.
[0066] It is understandable that when cutting off the other end sharp corner 107, the silicon rod edge block 10 is rotated in the second horizontal direction, and the above positioning method is used to control the diamond wire to cut off the other end sharp corner 107.
[0067] Specifically, when performing the step of cutting off the side arc block 106, the second positioning component 3 is used to position the silicon rod edge block 10. At this time, since the cutting path of the diamond wire remains unchanged, it is necessary to adjust the position of the silicon rod edge block 10 so that the edge of the side arc block 106 is located on the cutting path of the diamond wire. Therefore, the first positioning component 2 cannot meet the positioning requirements of the silicon rod edge block 10 at this time. At this time, the second positioning component 3 is used to position the silicon rod edge block 10 in the first horizontal direction and the second horizontal direction at the same time so that the diamond wire can complete the cutting of the side arc block 106.
[0068] Example 2
[0069] This embodiment provides a positioning fixture for cutting silicon rod edge blocks, which is largely the same in structure as Embodiment 1, with improvements only. Therefore, only the differences between the two are described here, and the structures identical to those in Embodiment 1 will not be repeated. In this embodiment, the same or corresponding technical features as in Embodiment 1 are referred to by the same reference numerals.
[0070] Specifically, in this embodiment, the second positioning component 3 includes a second positioning post 31 and two second clamping members 32. The second positioning post 31 is disposed on the base 1 and is adjacent to the second clamping members 32 along the second horizontal direction. The side of the second positioning post 31 is configured to abut against the side plane 101 to limit the silicon rod edge block 10 in the second horizontal direction. The two second clamping members 32 are disposed adjacent to each other on the base 1 along the first horizontal direction. The two second clamping members 32 can respectively abut against the two end planes 103 of the silicon rod edge block 10 to limit the silicon rod edge block 10 in the first horizontal direction.
[0071] Specifically, in this embodiment, the second positioning post 31 and the second clamping member 32 are arranged adjacent to each other along the second horizontal direction, while the two are staggered in the first horizontal direction.
[0072] When cutting the side arc block 106 of the silicon rod edge block 10, the second positioning component 3 described above can simultaneously limit the silicon rod edge block 10 in the first horizontal direction and the second horizontal direction.
[0073] Specifically, see Figures 8-10 When cutting the side arc block 106 of the silicon rod edge block 10, at least one end sharp corner 107 has been cut off on the silicon rod edge block 10, forming at least one end cut surface 104. The end cut surface 104 is placed downwards on the base 1, and the axial direction of the silicon rod edge block 10 (i.e., the original axial direction of the silicon rod) extends along the first horizontal direction. The side plane 101 of the silicon rod edge block 10 abuts against the side of the second positioning post 31, and the two second clamping members 32 are respectively pressed against the two end planes 103 of the silicon rod edge block 10. At this time, the movement of the silicon rod edge block 10 along the first and second horizontal directions is restricted. Then, the diamond wire is controlled to cut off the side arc block 106 according to the preset path.
[0074] Specifically, in this embodiment, the second clamping member 32 includes a second clamping member body 321 and a second clamping member top 322.
[0075] The second clamping member body 321 is disposed on the base 1. The position of the second clamping member top 322 is adjustablely disposed on the second clamping member body 321, and the second clamping member top 322 can abut against the end plane 103.
[0076] The position of the second clamping head 322 is adjustablely disposed on the second clamping body 321. In this way, the position of the second clamping head 322 can be adjusted according to the size of the silicon rod edge block 10 along its own axis, so that the positioning fixture for cutting silicon rod edge blocks can adapt to silicon rod edge blocks 10 of different sizes.
[0077] That is, when using the positioning fixture for cutting silicon rod edge blocks provided in this embodiment, the first step of cutting the silicon rod edge blocks must be to cut off one of the end sharp corners 107, the second step of cutting can be to cut off the other end sharp corner 107 or to cut off the side arc block 106, and finally the third step of cutting can be performed.
[0078] Example 3
[0079] This embodiment provides a positioning fixture for cutting silicon rod edge blocks, which is largely the same in structure as Embodiment 1, with improvements only. Therefore, only the differences between the two are described here, and the structures identical to those in Embodiment 1 will not be repeated. In this embodiment, the same or corresponding technical features as in Embodiment 1 are referred to by the same reference numerals.
[0080] Specifically, see Figures 8-10 In this embodiment, the second positioning component 3 includes a second positioning post 31 and a third clamping member 33. The second positioning post 31 is disposed on the base 1, and the side of the second positioning post 31 is configured to abut against the side plane 101 to limit the silicon rod edge block 10 in the second horizontal direction. The third clamping member 33 is disposed on the base 1 and can press against the end cut surface 104 of the silicon rod edge block 10 in the vertical direction.
[0081] When cutting the side arc block 106 of the silicon rod edge block 10, the second positioning component 3 described above can simultaneously limit the silicon rod edge block 10 in the first horizontal direction and the second horizontal direction.
[0082] Specifically, see Figures 8-10 When the side arc block 106 of the silicon rod edge block 10 is cut, both sharp corners 107 on the silicon rod edge block 10 are cut off, forming two end cut surfaces 104. One end cut surface 104 is placed downwards on the base 1, and the axial direction of the silicon rod edge block 10 (i.e., the original axial direction of the silicon rod) extends along the first horizontal direction, so that the side plane 101 of the silicon rod edge block 10 abuts against the side of the second positioning post 31. Then, the third clamping member 33 presses against the other end cut surface 104 of the silicon rod edge block 10 in the vertical direction. Under the limiting action of the second positioning post 31 and the third clamping member 33, the movement of the silicon rod edge block 10 along the first and second horizontal directions is restricted. Then, the diamond wire is controlled to cut off the side arc block 106 according to the preset path.
[0083] Optionally, in this embodiment, the third clamping member 33 is disposed at the top of the second positioning post 31.
[0084] This configuration eliminates the need for a support post on the base 1 for the third clamping member 33. This reduces the number of parts and lowers product costs.
[0085] That is, when using the positioning fixture for cutting silicon rod edge blocks provided in this embodiment, the first step of cutting the silicon rod edge blocks must be to cut off one of the end sharp corners 107, the second step of cutting must be to cut off the other end sharp corner 107, and finally the third step is to cut off the side arc block 106.
[0086] Example 4
[0087] This embodiment provides a positioning fixture for cutting silicon rod edge blocks, which is largely the same in structure as Embodiment 1, with improvements only. Therefore, only the differences between the two are described here, and the structures identical to those in Embodiment 1 will not be repeated. In this embodiment, the same or corresponding technical features as in Embodiment 1 are referred to by the same reference numerals.
[0088] Specifically, see Figure 3 and Figure 4 The first positioning component 2 also includes a third positioning post 23, which is disposed on the base 1 and adjacent to the first positioning post 21 along the second horizontal direction. The side of the third positioning post 23 is configured to abut against the side plane 101 of the silicon rod edge block 10. A fourth clamping member 24 is provided on the third positioning post 23, which can abut against the end plane 103 of the silicon rod edge block 10 in the vertical direction.
[0089] Furthermore, the first positioning component 2 also includes a fifth clamping member 25. The top end of the first positioning post 21 is provided with the fifth clamping member 25, which can abut against the end plane 103 of the silicon rod edge block 10 in the vertical direction.
[0090] Specifically, when positioning the silicon rod edge piece 10, the first positioning component 2 places the silicon rod edge piece 10 on the base 1, fits one end plane 103 of the silicon rod edge piece 10 against the upper surface of the base 1, abuts the side plane 101 of the silicon rod edge piece 10 against the side of the first positioning post 21, adjusts the position of the silicon rod edge piece 10 to the preset position, and then uses the first clamping member 22 to clamp the arc surface 102 of the silicon rod edge piece 10, and the fifth clamping member 25 clamps the end plane 103 of the silicon rod edge piece 10 in the vertical direction.
[0091] Specifically, the third positioning post 23 abuts against the surface of the end tip 107 to be cut off, and the fourth clamping member 24 abuts against the surface of the end tip 107 in the vertical direction. The side of the first positioning post 21 and the first clamping member 22 abut against the part of the silicon rod edge piece 10 that needs to be retained in this cutting step. In this way, the end tip 107 to be cut off can be limited, and the part of the silicon rod edge piece 10 that needs to be retained in this cutting step can also be limited, so as to fully prevent the silicon rod edge piece 10 from shifting during the cutting process.
[0092] Optionally, in this embodiment, in order to avoid the cutting path of the diamond wire, the base 1 is a split structure, including a first substrate 11 and a second substrate 12. The first substrate 11 and the second substrate 12 are arranged adjacent to each other along the second horizontal direction, and there is an avoidance gap between them.
[0093] The third positioning post 23 is located on the second substrate 12, and the first positioning post 21 and the first clamping member 22 are both located on the first substrate 11. That is, when placing the silicon rod edge piece 10, the end tip 107 to be cut off is located on the second substrate 12, and the part of the silicon rod edge piece 10 that needs to be retained in this cutting step is located on the first substrate 11.
[0094] With this configuration, the positioning fixture for cutting the edge of the silicon rod can be directly installed on the silicon rod processing device, and the diamond wire of the silicon rod processing device can be controlled to pass through the clearance gap between the first substrate 11 and the second substrate 12 from top to bottom.
[0095] Specifically, in Figure 4 , Figure 7 and Figure 10 In the diagram, a rectangle in space is used to illustrate the cutting path of the diamond wire, which is also known as the diamond wire cutting path simulation surface 5.
[0096] Of course, in other embodiments, the base 1 can also be an integral structure, including an integrally formed first substrate 11 and second substrate 12. There is a clearance groove between the first substrate 11 and the second substrate 12. When the diamond wire is controlled to cut the silicon rod edge block 10, the diamond wire of the silicon rod processing device is controlled to move from top to bottom toward the clearance groove until the diamond wire moves into the clearance groove.
[0097] Further, see Figures 5-7 In this embodiment, the positioning fixture for cutting silicon rod edge blocks also includes a third positioning component 4. The third positioning component 4 includes a movable clamping member 41. The movable clamping member 41 is adjustablely positioned on the base 1 along the first horizontal direction. The movable clamping member 41 can abut against the end cutting surface 104 of the silicon rod edge block 10 along the second horizontal direction.
[0098] It should be noted that, Figure 5A top-down view of the silicon rod edge piece being installed in the positioning fixture for cutting the silicon rod edge piece during the second cut.
[0099] After one end sharp corner 107 on the silicon rod edge block 10 is cut, when cutting the other end sharp corner 107, the first positioning component 2 and the third positioning component 4 are used to position the silicon rod edge block 10 simultaneously.
[0100] Specifically, when the second end sharp corner 107 is cut, the positioning method of the first positioning component 2 for the silicon rod edge piece 10 is the same as described above; after the first positioning component 2 completes the positioning of the silicon rod edge piece 10, the movable clamping member 41 abuts against the end cutting surface 104 of the silicon rod edge piece 10 along the second horizontal direction to form a more stable positioning of the silicon rod edge piece 10.
[0101] Specifically, the third positioning component 4 is located on the first substrate 11.
[0102] The movable clamping member 41 is adjustable in position on the base 1 along the first horizontal direction, so that the third positioning component 4 can meet the positioning requirements of silicon rod edge blocks 10 of different sizes.
[0103] Furthermore, in this embodiment, the third positioning component 4 also includes a fixed base 42 and a movable component 43.
[0104] The fixed base 42 is fixedly disposed on the base 1, and the fixed base 42 is provided with an adjustment hole that runs through the first horizontal direction; the movable part 43 is adjustablely disposed in the adjustment hole along the first horizontal direction, and the movable clamping part 41 is disposed at one end of the movable part 43.
[0105] That is, the position of the movable clamping member 41 can be adjusted by means of the fixed base 42 and the movable member 43.
[0106] Furthermore, in this embodiment, the third positioning component 4 also includes a movable locking component 44, one end of which is threaded through the fixed base 42 and located in the adjustment hole and can abut or separate from the movable component 43.
[0107] Once the position of the movable clamping member 41 is adjusted to the correct position, the movable locking member 44 is controlled to abut against the movable member 43, thereby locking the movable member 43 and preventing the movable clamping member 41 from shifting when positioning the silicon rod edge block 10.
[0108] Specifically, in this embodiment, the second positioning component 3 includes two second positioning posts 31, which are arranged adjacent to each other on the base 1 along the first horizontal direction. The side of the second positioning post 31 is configured to abut against the side plane 101 to limit the silicon rod edge block 10 along the second horizontal direction.
[0109] The two second positioning posts 31 limit the silicon rod edge block 10 along the second horizontal direction, forming two limiting points, which makes the limiting of the silicon rod edge block 10 more accurate.
[0110] More specifically, in this embodiment, the second positioning component 3 further includes two second clamping members 32. The second positioning post 31 is disposed on the base 1 and is adjacent to the second clamping member 32 along the second horizontal direction. The side of the second positioning post 31 is configured to abut against the side plane 101 to limit the silicon rod edge block 10 in the second horizontal direction. The two second clamping members 32 are disposed adjacent to each other on the base 1 along the first horizontal direction. The two second clamping members 32 can respectively abut against the two end planes 103 of the silicon rod edge block 10 to limit the silicon rod edge block 10 in the first horizontal direction.
[0111] Furthermore, in this embodiment, the second positioning component 3 also includes a third clamping member 33, which is disposed on the base 1 and can press against the end cut surface 104 of the silicon rod edge block 10 in the vertical direction. Specifically, the third clamping member 33 is disposed at the top of the second positioning post 31.
[0112] Specifically, see Figures 8-10 When cutting the side arc block 106 of the silicon rod edge block 10, both sharp corners 107 on the silicon rod edge block 10 are cut off, forming two end cut surfaces 104. One end cut surface 104 is placed downwards on the base 1, and the axial direction of the silicon rod edge block 10 (i.e., the original axial direction of the silicon rod) extends along the first horizontal direction, so that the side plane 101 of the silicon rod edge block 10 abuts against the side of the second positioning post 31. Then, the third clamping member 33 presses against the other end cut surface 104 of the silicon rod edge block 10 in the vertical direction. At the same time, the two second clamping members 32 are respectively pressed against the two end planes 103 of the silicon rod edge block 10. At this time, the movement of the silicon rod edge block 10 along the first and second horizontal directions is restricted. Then, the diamond wire is controlled to cut off the side arc block 106 according to the preset path.
[0113] Figure 8 A top-down view of the third cut performed when the silicon rod edge block is installed in the positioning fixture for cutting the silicon rod edge block.
[0114] Furthermore, when positioning the silicon rod edge block 10 using the second positioning component 3 described above, before cutting, the two second clamping members 32 are respectively pressed against the two ends of the side arc block 106 to limit the position of the side arc block 106 during the cutting process; the position pressed by the third clamping member 33 is the surface of the cuboid block that needs to be retained in the end.
[0115] Specifically, in the second positioning assembly 3, both second clamping members 32 are located on the second base plate 12, and the second positioning post 31 is located on the first base plate 11. Preferably, two second positioning posts 31 are provided on the first base plate 11, and the two second positioning posts 31 are arranged adjacent to each other along the first horizontal direction.
[0116] Preferably, in this embodiment, a first protective block is provided on the side of the first positioning post 21 so that the surface of the silicon rod edge block 10 directly abuts against the first protective block, thereby avoiding damage to the surface of the silicon rod edge block 10.
[0117] The second positioning post 31 has a second protective block on its side so that the surface of the silicon rod edge block 10 directly abuts against the first protective block, thus avoiding damage to the surface of the silicon rod edge block 10.
[0118] A third protective block 231 is provided on the side of the third positioning post 23 so that the surface of the silicon rod edge block 10 directly abuts against the first protective block, thereby avoiding damage to the surface of the silicon rod edge block 10.
[0119] Optionally, in this embodiment, the materials of the first protective block, the second protective block, and the third protective block 231 can all be polyesteramine, and the hardness can be 80 degrees.
