Description

Technical Field

[0001] The utility model relates to the technical field of silicon rod processing, in particular to a silicon rod supporting mechanism. Background Art

[0002] The loop wire cutting device is a device used to cut silicon rods into segments. During segmentation, the silicon rod is supported horizontally on a support mechanism and cut by a loop wire cutting head. Since the silicon rod is cylindrical, current silicon rod support mechanisms generally use two rows of rollers or V-shaped seats to support the circumferential wall of the silicon rod. However, due to the limitations of silicon rod processing accuracy, there are deviations in the axial cylindricity of the silicon rod. When the rollers or V-shaped seats support the silicon rod, it is difficult to ensure that the rollers or V-shaped seats are fully tangentially in contact with the silicon rod, resulting in unsupported areas of the silicon rod. When this area is cut into segments, gravity is redistributed at the moment the rod is cut through, causing the silicon rod to tilt or sink. The finished product segments will have defects such as broken edges, resulting in material damage and scrap. Utility Model Content

[0041] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0042] See also Figure 1-5 The silicon rod supporting mechanism proposed in an embodiment of the present invention includes a first supporting part 2 and a second supporting part 3.

[0043] The first support portion 2 includes multiple sets of telescopic support assemblies 21 spaced apart along a first horizontal direction. Each set of telescopic support assemblies 21 includes two support plates 211 arranged at an angle relative to each other. The support plates 211 are movable along their normal direction. The first support portion 2 supports the peripheral wall of the region to be cut of the silicon ingot 5.

[0044] The second support portion 3 includes a plurality of first V-shaped support assemblies 31 arranged at intervals along the first horizontal direction. The second support portion 3 can support the peripheral wall of the non-cutting area of ​​the silicon rod 5.

[0045] The support plates 211 in the first support portion 2 are capable of moving along their normal direction, ensuring that each support plate 211 is tangential to the circumferential wall of the silicon ingot 5. This provides stable support for the portion of the silicon ingot 5 to be cut, preventing the silicon ingot 5 from tilting or sinking during segmentation. This improves the precision of the finished product and reduces scrap rates. The circumferential wall of the non-cut portion of the silicon ingot 5, however, requires relatively low support precision and is supported by the multiple groups of first V-shaped support assemblies 31 included in the second support portion 3. Therefore, the use of first and second support portions 2, 3 with varying degrees of support precision to support the silicon ingot 5 in different zones effectively reduces the overall cost of the silicon ingot support mechanism.

[0046] Furthermore, each group of telescopic support assemblies 21 also includes two relative telescopic drive members 212, and the two telescopic drive members 212 correspond one to one to the two support plates 211. The telescopic drive members 212 drive the corresponding support plates 211 to drive the support plates 211 to move along their own normal directions, so as to flexibly adjust the support height of each support plate 211, and enable each support plate 211 to be tangent to the peripheral wall of the area to be cut of the silicon rod 5, so as to improve the support accuracy of the silicon rod 5.

[0047] Preferably, the telescopic drive member 212 is a high-capacity pneumatic support, which can self-lock after adjusting the support plate 211 to be tangential to the silicon rod 5, to ensure that the support plate 211 does not move axially and radially during the cutting process, thereby improving its support stability.

[0048] Furthermore, the first supporting portion 2 further includes a first supporting seat 22 .

[0049] The top of the first support base 22 is provided with multiple groups of mounting positions spaced apart along a first horizontal direction. Each group of mounting positions includes two opposing mounting slots 221. The mounting slots 221 are configured to accommodate the main bodies of the telescopic drive members 212 in a one-to-one correspondence, thereby reducing the overall volume of the first support portion 2. The driving ends of the telescopic drive members 212 are fixedly connected to corresponding support plates 211, which protrude from the mounting slots 221 to support the silicon rods 5.

[0050] Specifically, the longitudinal cross-section of the first support seat 22 is V-shaped, so as to be suitable for installing the inclined support plate 211 and being suitable for accommodating the peripheral wall of the silicon rod 5 .

[0051] Furthermore, the second support portion 3 further includes a second support seat 32 , and a plurality of first V-shaped support assemblies 31 are provided on the top of the second support seat 32 . The second support seat 32 is used to support the first V-shaped support assemblies 31 .

[0052] Specifically, each set of first V-shaped support assemblies 31 includes two first support blocks 311 that are oppositely and obliquely arranged. The first support blocks 311 are detachably fixed to the top of the second support base 32. The thickness of the first support blocks 311 is adjustable.

[0053] Since the first support block 311 is detachable, the thickness of the first support block 311 can be adjusted after the first support block 311 is removed. The thickness adjustment method is specifically as follows: grinding the first support block 311 to reduce the thickness of the first support block 311; or adding a pad between the first support block 311 and the second support seat 32 to increase the thickness of the first support block 311 (i.e., the overall thickness of the first support block 311 and the pad). In this way, the thickness of the first support block 311 can be flexibly adjusted, that is, the height of the supporting surface of the first support block 311 can be adjusted to reduce the gap between each first support block 311 and the peripheral wall of the silicon rod 5, thereby better tangent to and support the peripheral wall of the silicon rod 5.

[0054] During adjustment, a 0.02 mm thick feeler gauge can be used. If the feeler gauge cannot be inserted into the gap between the first support block 311 and the silicon rod 5 , the support gap requirement between the first support block 311 and the silicon rod 5 is met. This detection method is relatively simple and convenient.

[0055] Optionally, the first support block 311 is detachably fixed to the second support base 32 by screws to facilitate assembly and disassembly and thickness adjustment.

[0056] Preferably, the longitudinal cross-section of the second support seat 32 is V-shaped, so as to be adapted to the installation of the inclined first support block 311 and to the shape of the peripheral wall of the silicon rod 5 .

[0057] Furthermore, the silicon rod supporting mechanism further includes a slide support portion 1 .

[0058] The slide support portion 1 , the first support portion 2 and the second support portion 3 are arranged in sequence along a first horizontal direction.

[0059] The slide support 1 includes multiple sets of second V-shaped support assemblies 11 spaced apart along a first horizontal direction. The slide support 1 is movable along the first horizontal direction toward or away from the first support 2. The slide support 1 supports the silicon rod 5 near one end of the peripheral wall of the region to be cut.

[0060] During use, the slide support 1, the first support 2, and the second support 3 respectively support the peripheral wall of one end of the silicon rod 5 close to the area to be cut, the peripheral wall of the area to be cut of the silicon rod 5, and the peripheral wall of the non-cutting area of ​​the silicon rod 5, so as to support the entire peripheral wall of the silicon rod 5. After the silicon rod 5 is segmented once, the slide support 1 can drive the finished segment to move away from the first support 2 to cooperate with manual or unloading by a feeding robot, and move again towards the first support 2 after unloading is completed, so that after the remaining silicon rod 5 moves forward a set distance relative to the first support 2 and the second support 3, the slide support 1 supports the peripheral wall of one end of the remaining silicon rod 5 close to the area to be cut, waiting for the next segmented unloading.

[0061] Specifically, the slide support portion 1 further includes a slide support seat 12 , and a plurality of second V-shaped support assemblies 11 are provided on the top of the slide support seat 12 . The slide support seat 12 is used to support the second V-shaped support assemblies 11 .

[0062] Specifically, each set of second V-shaped support assemblies 11 includes two second support blocks 111 disposed opposite and at an angle. The second support blocks 111 are detachably fixed to the top of the slide support base 12. The thickness of the second support blocks 111 is adjustable. The thickness adjustment method of the second support blocks 111 is the same as that of the first support blocks 311 and will not be further described here.

[0063] Optionally, the second support block 111 is detachably fixed to the slide support seat 12 by screws to facilitate assembly and disassembly and thickness adjustment.

[0064] Preferably, the longitudinal cross-section of the slide support seat 12 is V-shaped, so as to be suitable for installing the inclined second support block 111 and for accommodating the peripheral wall of the silicon rod 5 .

[0065] Furthermore, the slide support portion 1 further includes a slide rail 13 extending along the first horizontal direction, and the slide support seat 12 is slidably disposed on the slide rail 13 to improve the movement accuracy of the slide support seat 12 .

[0066] Optionally, the slide rail 13 is a rack and pinion slide rail. The slide support 12 is driven to move along the slide rail 13 by a servo motor.

[0067] Preferably, the slide support seat 12, the first support seat 22 and the second support seat 32 are all castings to ensure rigidity and V-shaped processing accuracy.

[0068] Furthermore, a supporting platform 4 is also included.

[0069] The top of the support platform 4 is provided with a slide support portion 1 , a first support portion 2 and a second support portion 3 .

[0070] Preferably, the first support seat 22 and the second support seat 32 are an integral piece to facilitate processing and assembly.

[0071] Specifically, the slide rail 13 and the main body of the servo motor are both arranged on the supporting platform 4 .
