Description

Technical Field

[0001] This application relates to the technical field of silicon crystal cutting, and particularly to a slicing machine. Background Art

[0002] A slicing machine is an important processing device in the photovoltaic industry. The slicing machine uses a diamond wire to cut a silicon crystal rod. Through the diamond wire that winds around the cutting main roller and makes a high-speed reciprocating movement, and in cooperation with a control system, the silicon crystal rod is cut into silicon wafers.

[0003] Determined by the mechanical properties of multi-wire cutting with diamond wire, for the cutting of a silicon crystal rod with a fixed size, the smaller the distance between the main roller shafts, 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. The slicing machine can cut silicon crystal rods of different specifications by changing the distance between the main roller shafts. Currently, the slicing machine often uses an eccentric axle box to adjust the distance between the main roller shafts to adapt to silicon crystal rods of different specifications. However, using an eccentric axle box will affect the rotational accuracy of the main roller, causing the cutting wire mesh to jump, thereby affecting the yield of the silicon wafers. Summary of the Utility Model

Detailed implementation manners

[0038] To make the objectives, technical solutions and advantages of the present application clearer, the following describes the present application in further detail with reference to the accompanying drawings and by way of examples.

[0039] Figure 1 A schematic structural diagram of a slicing machine provided for an embodiment of the present application, as Figure 1 shown, a slicing machine 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. Among them, 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 spacing between the first main roller assembly 1 and the second main roller assembly 2 is 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 ingot is transported to the cutting chamber frame 0 by the loading mechanism for cutting. By replacing different axle box seat assemblies 3, the axial distance between the first main roller assembly 1 and the second main roller assembly 2 is adjusted to meet the dimensional requirements of silicon ingots of different specifications. At the same time, it can also keep the first main roller assembly 1 and the second main roller assembly 2 with high rotational accuracy, improve the yield of silicon ingot slicing. And it can also reduce the wear of the axle box and improve the service life of the axle box.

[0041] Figure 2 The structural schematic diagram of the slicing machine provided by another embodiment of the present application is shown as Figure 2 shown. The slicing machine further 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 peripheries 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 only two main roller assemblies are provided in the slicing machine, the diamond wire 7 is wound around the outer peripheries of the two main roller assemblies, and the diamond wire 7 has two parallel upper and lower wire bodies. The upper wire body is called the first part wire body, and the lower wire body is called the second part wire body. When cutting the silicon ingot, the silicon ingot gradually approaches the upper first part wire body from the outside of the diamond wire 7, and the first part wire body cuts the silicon ingot. Since the two parallel wire bodies are relatively close, the lower second part wire body is likely to re-cut the cut silicon wafers, causing damage to the silicon wafers. The third main roller assembly 6 of the present application can support the lower second part wire body to make the diamond wire as a whole in a triangle. In this way, the second part wire body is far from the first part wire body, meeting sufficient cutting space and avoiding re-cutting the cut silicon wafers.

[0042] Figure 3 The structural schematic diagram of the first main roller assembly or the second main roller assembly or the third main roller assembly provided by an embodiment of the present application is shown as Figure 3 shown. The first main roller assembly 1 includes a driving axle box 11, a driven axle box 12 and a main roller 13. The two ends of the main roller 13 are respectively connected to the driving axle box 11 and the driven axle box 12, and the structures and dimensions 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 above diamond wire 7 is wound around the outer peripheries 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 that 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 that 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 according to needs. It should be noted that even though the diameter of the main roller 13 of the third main roller assembly 6 is smaller than that of the main roller 13 of the first main roller assembly 1, the diameters of the drive axle boxes 11 and the driven axle boxes 12 of the three main roller assemblies are the same.

[0044] The present application provides two implementation manners of the axle box seat assembly 3 to realize the adjustment of the axial distance between the first main roller assembly 1 and the second main roller assembly 2. The first implementation manner is to integrate the first support structure 4 and the second support structure 5 into one body, and the second implementation manner is to set the first support structure 4 and the second support structure 5 as a split type. The following specifically introduces these two implementation manners:

[0045] Embodiment 1:

[0046] Figure 4 FIG. 10 is a schematic structural diagram of a slicing machine provided for Embodiment 1 of the present application; Figure 5 FIG. 11 is an exploded view of the slicing machine provided for Embodiment 1 of the present application. Combining 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, and the first mounting hole 011 and the second mounting hole 012 are respectively located on opposite sides of the cutting chamber frame 0. Each axle box seat assembly 3 includes a first drive axle box seat 31 and a first driven axle box seat 32, and the first drive axle box seat 31 and the first driven axle box seat 32 are symmetrically installed on opposite sides of the cutting chamber frame 0, that is, the first drive axle box seat 31 is installed in the first mounting hole 011, and the first driven axle box seat 32 is installed in the second mounting hole 012. The shape of the first mounting hole 011 is adapted to that of the first drive axle box seat 31, and the shape of the second mounting hole 012 is adapted to that of the first driven axle box seat 32. During installation, the first drive axle box seat 31 and the first driven axle box seat 32 can be respectively connected to the cutting chamber frame 0 through mounting flanges 8. The first drive axle box seat 31 and the first driven axle box seat 32 can both be inserted into the first fixing structure 01 of the cutting chamber frame 0 from the left side, so that the mounting flange 8 of the first drive axle box seat 31 is located outside the cutting chamber frame 0, and the mounting flange 8 of the first driven axle box seat 32 is located inside the cutting chamber frame 0. Alternatively, the first drive axle box seat 31 and the first driven axle box seat 32 can both be inserted into the first fixing structure 01 of the cutting chamber frame 0 from the right side, so that the mounting flange 8 of the first drive axle box seat 31 is located inside the cutting chamber frame 0, and the mounting flange 8 of the first driven axle box seat 32 is located outside the cutting chamber frame 0. The first fixing structure 01 provides an installation position for the axle box seat assembly 3, which is convenient for the maintenance and replacement of the axle box seat assembly 3.

[0047] The first driving axle housing base 31 and the first driven axle housing base 32 are respectively fixedly installed on the cutting chamber frame 0 by screws and pins. Specifically, the mounting flange 8 of the first driving axle housing base 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) corresponding to the first through hole 81, and a plurality of threaded holes (not shown in the figure) corresponding to the screw through holes 82. During installation, insert the first driving axle housing base 31 into the first mounting hole 011, align the first through hole 81 with the second through hole, then insert the pin through the first through hole 81 and the second through hole in sequence to achieve the alignment of the first driving axle housing base 31 and the cutting chamber frame 0. Finally, tighten the screws through the screw through holes 82 and the threaded holes to complete the installation of the first driving axle housing base 31. The number of the above-mentioned screws is at least 6 and they are evenly distributed on the mounting flange 8 of the first driving axle housing base 31, which can make the first driving axle housing base 31 firmly installed and evenly stressed. The structure of the first driven axle housing base 32 is the same as that of the first driving axle housing base 31, and it is also fixed on the cutting chamber frame 0 by the above-mentioned installation method, and its specific installation process will not be elaborated here.

[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 driving axle housing base 31 and the first driven axle housing base 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 specifically setting the above components, namely the first main roller assembly 1, the second main roller assembly 2 and the third main roller assembly 6, the first main roller assembly 1 and the second main roller assembly 2 can be arranged on the same horizontal plane, and the third main roller assembly 6 is located below this horizontal plane. The silicon ingot 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 driving axle box seat 31 and the first driven axle box seat 32 respectively have three holes for installing the above-mentioned first main roller assembly 1, second main roller assembly 2 and third main roller assembly 6. Specifically, the first support structure 4 for installing 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 in the first driving axle box seat 31, and the second support hole 42 is located in the first driven axle box seat 32. The first support hole 41 and the second support hole 42 are coaxially arranged. The driving axle box 11 of the first main roller assembly 1 is installed in the first support hole 41, and the driven axle box 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 in the first driving axle box seat 31, and the fourth support hole 52 is located in the first driven axle box seat 32. The third support hole 51 and the fourth support hole 52 are coaxially arranged. The driving axle box 11 of the second main roller assembly 2 is installed in the third support hole 51, and the driven axle box 12 of the second main roller assembly 2 is installed in the fourth support hole 52. The axle box seat assembly 3 further includes a third support structure 9. 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 driving axle box seat 31, and the sixth support hole 92 is located in the first driven axle box seat 32. The fifth support hole 91 and the sixth support hole 92 are coaxially arranged. The driving axle box 11 of the third main roller assembly 6 is installed in the fifth support hole 91, and the driven axle box 12 of the third main roller assembly 6 is installed in the sixth support hole 92.

[0050] When specifically preparing the above-mentioned axle box seat assembly 3, a combined machining process is adopted. Combined machining means that the driving axle box seat and the driven axle box seat of each group of axle box seat assemblies 3 are machined simultaneously, that is, two coaxial holes are machined simultaneously, which can ensure that the concentric accuracy of the two opposite support holes is relatively high. Specifically, first install the first driving axle box seat 31 in the first installation hole 011, install the first driven axle box seat 32 in the second installation hole 012, and fix the first driving axle box seat 31 and the first driven axle box seat 32 with screws and pins respectively. Then, simultaneously machine the support holes of the main roller assembly to make the first support hole 41 and the second support hole 42 coaxial, the third support hole 51 and the fourth support hole 52 coaxial, and the fifth support hole 91 and the sixth support hole 92 coaxial. The above three groups of support holes are all prepared by the combined machining process, ensuring the concentric accuracy requirements of the two support holes of each main roller assembly.

[0051] The hole pitch between the first support hole 41 and the third support hole 51 is L, and this hole pitch refers to the distance between the axes of the two holes. The hole pitch between the second support hole 42 and the fourth support hole 52 is also L. Thus, the axial pitch between the first main roller assembly 1 and the second main roller assembly 2 is L. The hole pitch L of any two sets of axle box seat assemblies 3 is different, so that the axial pitch between the first main roller assembly 1 and the second main roller assembly 2 is different, to adapt to the cutting of silicon ingots of different sizes. Multiple axle box seat assemblies 3 can have different axial pitches 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 pitch L1, and the second axle box seat assembly has an axial pitch L2, where L1 and L2 are not equal. Of course, L1 and L2 can also be made equal, so that the assemblies with the same axial pitch can be used as spares and can be replaced when the axle box seat assembly is damaged.

[0052] The application does not specifically limit the axial pitch between the third main roller assembly 6 and the first main roller assembly 1, and the axial pitch 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, it can be set according to requirements.

[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.

After being positioned by pins, they are fixed to the second fixing structure 02 with screws, and details are not elaborated in this application.

[0059] When preparing the above-mentioned first sub-assembly 301 and second sub-assembly 302, the combined machining process is also adopted for machining.

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. The first mounting seat 021 also has a seventh mounting hole 0213, and the second mounting seat 022 also has an eighth mounting hole 0223. The driving axle box 11 of the third main roller assembly 6 is installed in the seventh mounting hole 0213, and the driven axle box 12 of the third main roller assembly 6 is installed in the eighth mounting hole 0223.

[0061] The cross-sections of the second driving axle box seat 33 and the second driven axle box seat 34 are both elliptical, the seventh support hole 43 and the eighth support hole 44 are circular holes, the axis of the seventh support hole 43 is located on the major axis of the elliptical cross-section of the second driving axle box seat 33, and the axis of the eighth support hole 44 is located on the major axis of the elliptical cross-section of the second driven axle box seat 34. The cross-sections of the third driving axle box seat 35 and the third driven axle box seat 36 are both elliptical, the ninth support hole 53 and the tenth support hole 54 are circular holes, the axis of the ninth support hole 53 is located on the major axis of the elliptical cross-section of the third driving axle box seat 35, and the axis of the tenth support hole 54 is located on the major axis of the elliptical cross-section of the third driven axle box seat 36. The seventh support hole 43 and the ninth support hole 53 are spaced apart by a preset distance L, and the eighth support hole 44 and the tenth support hole 54 are also spaced apart by the preset distance L. The elliptical cross-section makes the cross-sectional areas of the second driving axle box seat 33 and the second driven axle box seat 34 relatively large, and multiple positions for opening circular holes can be provided along the major axis of the ellipse. Since the position of the second fixing structure 02 is fixed, the axial distance between the first main roller assembly 1 and the second main roller assembly 2 can be made different by installing different axle box seat assemblies 3.

Figure 9 It is a position relationship diagram of the second driving axle box seat and the seventh support hole provided by another embodiment of the present application. As Figure 8 shown, for example, the center distance between the seventh support hole 43 and the ninth support hole 53 is L3. Correspondingly, the center distance between the eighth support hole (not shown in the figure) and the tenth support hole (not shown in the figure) is also L3, so that the axial distance between the first main roller assembly 1 and the second main roller assembly 2 is L3. As Figure 9 shown, the center distance between the seventh support hole 43 and the ninth support hole 53 is L4. Correspondingly, the center distance between the eighth support hole (not shown in the figure) and the tenth support hole (not shown in the figure) is also L4, so that the axial distance between the first main roller assembly 1 and the second main roller assembly 2 is L4.

[0063] In this embodiment, the axle box seat assembly 3 is of a split design, separating the first support structure 4 from the second support structure 5, which saves materials. And it is convenient to replace when the first sub-assembly 301 or the second sub-assembly 302 is damaged.
