Description

Technical Field

[0001] The present application relates to the technical field of silicon crystal cutting, and in particular to a slicer. Background Art

[0002] The slicer is an important processing equipment in the photovoltaic industry. The slicer uses diamond wire to cut silicon crystal rods. The diamond wire wound on the cutting main roller and running back and forth at high speed cooperates with the control system to cut the silicon crystal rod into silicon wafers.

[0003] Determined by the mechanical properties of diamond wire multi-wire cutting, for the cutting of silicon crystal rods of fixed size, the smaller the main roller axis spacing, the better the support for the diamond wire, the higher the cutting performance, the better the surface quality of the silicon wafer, and the higher the yield rate. The slicer can cut silicon crystal rods of different specifications by changing the main roller axis spacing. At present, the slicer often uses an eccentric shaft box to adjust the main roller axis spacing to adapt to silicon crystal rods of different specifications, but the use of an eccentric shaft box will affect the rotation accuracy of the main roller, causing the cutting wire net to jump, thereby affecting the yield rate of silicon wafers.

DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application is further described in detail below with reference to the accompanying drawings.

[0039] Figure 1 A schematic diagram of the structure of a slicer provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, a slicer provided by an embodiment of the present application includes a cutting chamber frame 0, a first main roller assembly, a second main roller assembly 2 and a plurality of axle box seat assemblies 3. Each of the plurality of axle box seat assemblies 3 can be detachably mounted on the cutting chamber frame 0. Each axle box seat assembly 3 includes a first support structure 4 and a second support structure 5, the first main roller assembly 1 is mounted on the first support structure 4, and the second main roller assembly 2 is mounted on the second support structure 5. The first support structure 4 and the second support structure 5 fix the first main roller assembly 1 and the second main roller assembly 2 to the cutting chamber frame 0. The first support structure 4 and the second support structure 5 are spaced apart by a preset distance, and the preset distances between the first support structure 4 and the second support structure 5 of any two axle box seat assemblies 3 are different, so that the axial spacings between the first main roller assembly 1 and the second main roller assembly 2 are different. The first main roller assembly 1 and the second main roller assembly 2 are parallel to each other.

[0040] In the above implementation, the silicon crystal rod is transported to the cutting chamber frame 0 by the feeding mechanism for cutting. The axis spacing between the first main roller assembly 1 and the second main roller assembly 2 is adjusted by replacing different axle box seat assemblies 3 to meet the size requirements of silicon crystal rods of different specifications. At the same time, the first main roller assembly 1 and the second main roller assembly 2 can maintain a high rotation accuracy, thereby improving the yield rate of silicon crystal rod slices. In addition, the wear of the axle box can be reduced and the life of the axle box can be improved.

[0041] Figure 2 A schematic diagram of the structure of a slicer provided in another embodiment of the present application. Figure 2 As shown, the slicer also includes a third main roller assembly 6 and a diamond wire 7. The first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6 are arranged in a triangle and are parallel to each other, and the diamond wire 7 is wound around the outer periphery of the first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6. The third main roller assembly 6 is used to support the diamond wire 7. When the slicer is only provided with two main roller assemblies, the diamond wire 7 is wound around the outer periphery of the two main roller assemblies, and the diamond wire 7 is in two parallel upper and lower wire bodies, the upper wire body is called the first wire body, and the lower wire body is called the second wire body. When the silicon crystal rod is cut, the silicon crystal rod gradually approaches the first wire body of the upper layer from the outside of the diamond wire 7, and the first wire body cuts the silicon crystal rod. Since the two parallel wire bodies are close to each other, the second wire body of the lower layer is easy to cut the cut silicon wafer for the second time, causing damage to the silicon wafer. The third main roller assembly 6 of the present application can support the second wire body of the lower layer, so that the diamond wire is triangular as a whole. In this way, the second part of the wire body is far away from the first part of the wire body, which provides sufficient cutting space and avoids secondary cutting of the already cut silicon wafer.

[0042] Figure 3 A schematic diagram of the structure of a first main roller assembly, a second main roller assembly, or a third main roller assembly provided in an embodiment of the present application. Figure 3 As shown, the first main roller assembly 1 includes a driving shaft box 11, a driven shaft box 12 and a main roller 13. The two ends of the main roller 13 are respectively connected to the driving shaft box 11 and the driven shaft box 12, and the structure and size of the first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6 can be the same. The diamond wire 7 is wound around the outer circumference of the three main rollers 13.

[0043] In another implementation, the diameter of the main roller 13 of the first main roller assembly 1 is the same as the diameter of the main roller 13 of the second main roller assembly 2, and the diameter of the main roller 13 of the third main roller assembly 6 is smaller than the diameter of the main roller 13 of the first main roller assembly 1. The size of the main roller 13 of the third main roller assembly 6 can be selected as needed. It is worth noting that even if the diameter of the main roller 13 of the third main roller assembly 6 is smaller than the diameter of the main roller 13 of the first main roller assembly 1, the diameters of the driving shaft box 11 and the driven shaft box 12 of the three main roller assemblies are the same.

[0044] The present application provides two implementations of the axle box seat assembly 3 to achieve the adjustment of the axial distance between the first main roller assembly 1 and the second main roller assembly 2. The first implementation is to integrate the first support structure 4 and the second support structure 5 into one body, and the second implementation is to set the first support structure 4 and the second support structure 5 as a split type. The two implementations are described in detail below:

[0045] Embodiment 1:

[0046] Figure 4 This is a schematic diagram of the structure of a slicer provided in the first embodiment of the present application. Figure 5 This is an exploded view of a slicer provided in the first embodiment of the present application. Figure 4 and Figure 5 The cutting chamber frame 0 has a first fixing structure 01. Specifically, the first fixing structure 01 includes a first mounting hole 011 and a second mounting hole 012. The first mounting hole 011 and the second mounting hole 012 are respectively located on opposite sides of the cutting chamber frame 0. Each shaft box seat assembly 3 includes a first active shaft box seat 31 and a first driven shaft box seat 32. The first active shaft box seat 31 and the first driven shaft box seat 32 are symmetrically installed on opposite sides of the cutting chamber frame 0, that is, the first active shaft box seat 31 is installed in the first mounting hole 011, and the first driven shaft box seat 32 is installed in the second mounting hole 012. The first mounting hole 011 is adapted to the shape of the first active shaft box seat 31, and the second mounting hole 012 is adapted to the shape of the first driven shaft box seat 32. During installation, the first active shaft box seat 31 and the first driven shaft box seat 32 can be connected to the cutting chamber frame 0 through the mounting flange 8 respectively. The first active shaft housing seat 31 and the first driven shaft housing seat 32 can both be inserted into the first fixed structure 01 of the cutting chamber frame 0 from the left side, so that the mounting flange 8 of the first active shaft housing seat 31 is located outside the cutting chamber frame 0, and the mounting flange 8 of the first driven shaft housing seat 32 is located inside the cutting chamber frame 0. Alternatively, the first active shaft housing seat 31 and the first driven shaft housing seat 32 can both be inserted into the first fixed structure 01 of the cutting chamber frame 0 from the right side, so that the mounting flange 8 of the first active shaft housing seat 31 is located inside the cutting chamber frame 0, and the mounting flange 8 of the first driven shaft housing seat 32 is located outside the cutting chamber frame 0. The first fixed structure 01 provides a mounting position for the shaft housing seat assembly 3, which is convenient for the maintenance and replacement of the shaft housing seat assembly 3.

[0047] The first active shaft housing seat 31 and the first driven shaft housing seat 32 are fixedly mounted on the cutting chamber frame 0 by screws and pins, respectively. Specifically, the mounting flange 8 of the first active shaft housing seat 31 has a first through hole 81 and a plurality of screw through holes 82. The cutting chamber frame 0 has a second through hole (not shown in the figure) arranged corresponding to the first through hole 81, and a plurality of threaded holes (not shown in the figure) arranged corresponding to the screw through hole 82. During installation, the first active shaft housing seat 31 is inserted into the first mounting hole 011 so that the first through hole 81 is opposite to the second through hole, and then the pin is sequentially passed through the first through hole 81 and the second through hole to achieve the alignment of the first active shaft housing seat 31 and the cutting chamber frame 0, and finally the screw is passed through the screw through hole 82 and tightened with the threaded hole to complete the installation of the first active shaft housing seat 31. The number of the above-mentioned screws is at least 6, which are evenly distributed on the mounting flange 8 of the first active shaft housing seat 31, so that the first active shaft housing seat 31 can be firmly installed and evenly stressed. The structure of the first driven shaft box seat 32 is the same as that of the first driving shaft box seat 31, and is also fixed to the cutting chamber frame 0 by the above-mentioned installation method, and the specific installation process will not be described in detail.

[0048] The first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6 are respectively installed between the first active shaft box seat 31 and the first driven shaft box seat 32. The first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6 are arranged in a triangle and are parallel to each other. When the first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6 are specifically arranged, the first main roller assembly 1 and the second main roller assembly 2 can be arranged in the same horizontal plane, and the third main roller assembly 6 is located below the horizontal plane. The silicon crystal rod enters the cutting chamber frame 0 from above the first main roller assembly 1 and the second main roller assembly 2, and gradually approaches the diamond wire 7 between the first main roller assembly 1 and the second main roller assembly 2 for cutting.

[0049] The first active shaft housing seat 31 and the first driven shaft housing seat 32 respectively have three holes for mounting the above-mentioned first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6. Specifically, the first support structure 4 for mounting the first main roller assembly 1 includes a first support hole 41 and a second support hole 42, the first support hole 41 is located at the first active shaft housing seat 31, the second support hole 42 is located at the first driven shaft housing seat 32, and the first support hole 41 and the second support hole 42 are coaxially arranged. The active shaft housing 11 of the first main roller assembly 1 is installed in the first support hole 41, and the driven shaft housing 12 of the first main roller assembly 1 is installed in the second support hole 42. The second support structure 5 includes a third support hole 51 and a fourth support hole 52, the third support hole 51 is located at the first active shaft housing seat 31, the fourth support hole 52 is located at the first driven shaft housing seat 32, and the third support hole 51 and the fourth support hole 52 are coaxially arranged. The active shaft box 11 of the second main roller assembly 2 is installed in the third support hole 51, and the driven shaft box 12 of the second main roller assembly 2 is installed in the fourth support hole 52. The shaft box seat assembly 3 also includes a third support structure 9, and the third main roller assembly 6 is installed in the third support structure 9. The third support structure 9 includes a fifth support hole 91 and a sixth support hole 92. The fifth support hole 91 is located in the first active shaft box seat 31, and the sixth support hole 92 is located in the first driven shaft box seat 32. The fifth support hole 91 is coaxially arranged with the sixth support hole 92. The active shaft box 11 of the third main roller assembly 6 is installed in the fifth support hole 91, and the driven shaft box 12 of the third main roller assembly 6 is installed in the sixth support hole 92.

[0050] When preparing the above-mentioned axle box seat assembly 3, a combined processing technology is used for processing. Combined processing refers to processing the active axle box seat and the driven axle box seat of each group of axle box seat assemblies 3 at the same time, that is, processing the two coaxial holes at the same time, so that the concentricity accuracy of the two relative support holes can be guaranteed to be high. Specifically, first install the first active axle box seat 31 in the first mounting hole 011, and the first driven axle box seat 32 in the second mounting hole 012, and fix the first active axle box seat 31 and the first driven axle box seat 32 with screws and pins respectively, and then process the support holes of the main roller assembly at the same time, so that the first support hole 41 is coaxial with the second support hole 42, the third support hole 51 is coaxial with the fourth support hole 52, and the fifth support hole 91 is coaxial with the sixth support hole 92. The above three groups of support holes are all prepared by a combined processing technology, which ensures the concentricity accuracy requirements of the two support holes of each main roller assembly.

[0051] The hole spacing between the first support hole 41 and the third support hole 51 is L, which refers to the distance between the two hole axes. The hole spacing between the second support hole 42 and the fourth support hole 52 is also L. As a result, the axial spacing between the first main roller assembly 1 and the second main roller assembly 2 is L. The hole spacing L of any two sets of axle box seat assemblies 3 are different, so that the axial spacing L of the first main roller assembly 1 and the second main roller assembly 2 is different to adapt to the cutting of silicon crystal rods of different sizes. Multiple axle box seat assemblies 3 can have different axial spacings L, for example, the axle box seat assembly 3 includes a first axle box seat assembly, a second axle box seat assembly, etc., the first axle box seat assembly has an axial spacing L1, and the second axle box seat assembly has an axial spacing L2, wherein L1 and L2 are not equal. Of course, L1 and L2 can also be made equal, so that components with the same axial spacing can be used as spares and can be replaced when the axle box seat assembly is damaged.

[0052] This application does not impose any specific restrictions on the axial distance between the third main roller assembly 6 and the first main roller assembly 1, and the axial distance between the third main roller assembly 6 and the second main roller assembly 2. As long as the third main roller assembly 6 does not interfere with the first main roller assembly 1 and the second main roller assembly 2, they can be set as required.

[0053] In this embodiment, the first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6 are all installed on the axle box seat assembly 3, which is convenient for processing and assembling the equipment.
