Description

Technical Field

[0001] The utility model relates to the technical field of silicon rod processing equipment, in particular to a cutting and grinding integrated machine and a cutting table device thereof. Background Art

[0002] With the development of the industry (photovoltaic industry), the demand for half-cell batteries has gradually expanded, which has led to a gradual expansion of the industry's demand for half-rod silicon wafer products. The half-rod can be formed by cutting the square silicon rod commonly used in the past, specifically cutting along the length direction of the square silicon rod to form two half-rods, so that most of the old production line can be used. In the entire production process from round silicon rods to silicon wafers, only the process of half-cutting the square silicon rod needs to be added. However, the production efficiency of some newly applied equipment in the current industry is still relatively low, such as the "cutting and grinding machine and its control method, medium, and computer equipment" disclosed in Chinese invention patent application publication number CN 117140763 A, the "square silicon rod cutting and grinding machine" disclosed in CN 115946248 A, and the "square silicon rod cutting and grinding machine" disclosed in CN 115871115 A, which are newly applied equipment that cuts the squared silicon rod into two square silicon rods (half-rods), but they still have low efficiency. Utility Model Content

[0003] To this end, the researchers of the applicant have attempted to use a circular wire cutting method to simultaneously cut two parallel silicon rods to improve their work efficiency.

[0033] The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used here are only for describing specific embodiments and are not intended to limit the present application. Spatially related terms, such as "front", "back", "left", "right", "up", "down", "below", "below", "lower", "lower", etc., can be used in the text to facilitate the description of the relationship between an element or feature shown in the figure and another element or feature.

[0034] Although the terms first, second, etc. are used in some instances herein to describe various elements or parameters, these elements or parameters should not be limited by these terms. These terms are only used to distinguish one element or parameter from another element or parameter. For example, a first support may be referred to as a second support, and similarly, a second support may be referred to as a first support; and a first support may be referred to as a second support, and similarly, a second support may be referred to as a first support, without departing from the scope of the various described embodiments.

[0035] like Figures 1 to 3 As shown, a cutting table device provided by the utility model is applied to a cutting and grinding machine, the cutting table device includes a support table assembly 10 and a first support 20 and a second support 30, the support table assembly 10 includes a middle support table 11 and a first support table 12 and a second support table 13, the first support table 12 and the second support table 13 are respectively located on both sides of the middle support table 11, the first support table 12 cooperates with the middle support table 11 to place a silicon rod 03, and the second support table 13 cooperates with the middle support table 11 to place another silicon rod 04.

[0036] like Figures 1 to 5 As shown, the second support 30 includes a first support 31, a first telescopic support 32, a second telescopic support 33, and a second support 34 arranged in sequence. One end of the first support platform 12 is fastened to the first support 20, and the other end is fastened to the first support 31. One end of the second support platform 13 is fastened to the first support 20, and the other end of the second support platform 13 is fastened to the second support 34. One end of the middle support platform 11 is fastened to the first support 20, and the other end is supported by the top plate 321 of the first telescopic support 32 and the top plate 331 of the second telescopic support 33.

[0037] In addition, one end of the middle support platform 11 and the first support platform 12 and the second support platform 13 can also be fixedly set on the first support 20, the other end of the first support platform 12 can also be fixedly set on the first support 31, and the other end of the second support platform 13 can also be fixedly set on the second support 34.

[0038] like Figure 1 and Figure 2 As shown, the silicon rods 03 and 04 to be cut are generally arranged side by side on the cutting table device. Figure 1 and Figure 2 The figure shows a partial structure of the loop wire cutting device 01, omitting its mounting frame and other structures, and shows an optional embodiment of the loop wire 02 for cutting and a guide wheel (including a cutting wheel and a transition wheel) supporting the loop wire. For the specific structure and other parts of the loop wire cutting device, reference may be made to various other prior arts, and those skilled in the art may also understand the loop wire cutting device accordingly.

[0039] If you need to replace the circular cutting line 02, refer to Figure 6 and Figure 7 As shown, the telescopic rod of the second telescopic support 33 is lowered to drive the top plate 331 of the second telescopic support 33 to lower, so that a part of the new annular cutting line 02 can be put in and bypass the top of the top plate 331 (the old annular cutting line 02 can also bypass the top of the top plate 331) (see Figure 6), and then the telescopic rod of the second telescopic support 33 rises and drives the top plate 331 of the second telescopic support 33 to rise to support the middle support platform 11, and then the telescopic rod of the first telescopic support 32 descends and drives the top plate 321 of the first telescopic support 32 to descend, and a part of the new annular cutting line 02 can be put in and bypass the top plate 321 (the old annular cutting line 02 can also bypass the top plate 321) (refer to Figure 7 state, combined Figure 6 ), then the telescopic rod of the first telescopic support 32 rises and drives the top plate 321 of the first telescopic support 32 to rise to support the middle support platform 11, so that the new annular cutting line 02 can be replaced (or the old cutting line can be taken out simultaneously or separately). During the replacement process, the position of the middle support platform 11 can be kept unchanged without the need for more precision adjustment or correction.

[0040] Among them, since one end of the middle support platform 11 is fastened or fixed on the first support 20, one of the two top plates 321 and 331 at the other end can play a supporting role to maintain the position of the middle support platform 11, and the top plate 321 and the top plate 331 can be larger or smaller. Because one end of the middle support platform 11 is generally installed on the first support 20 by at least two fasteners (in addition, a single set is also possible, because in general, the contact position between the middle support platform 11 and the first support 20 is generally a surface contact or multiple point contacts located on the same surface or a combination thereof).

[0041] In addition, the other end of the middle support platform 11 can be directly placed on the top plate 321 and the top plate 331, or it can be fastened by fasteners. Even if it is not fastened, after the silicon rods 03 and 04 are placed, the corresponding clamping mechanism will clamp (front and back and / or left and right) the silicon rods 03 and 04, and the clamping mechanism will at least be partially arranged on the first support platform 12 and the second support platform 13. Therefore, after the silicon rods 03 and 04 are clamped, it is equivalent to that the middle support platform 11 is also pre-tightened. Therefore, the other end of the middle support platform 11 can be directly placed on the top plate 321 and the top plate 331 or fastened by adding fasteners.

[0042] In a preferred embodiment, if Figures 1 to 5As shown, the second support 30 also includes a connecting guard plate 35, the two ends 351 / 352 of which are fastened to the first support 31 and the second support 34, respectively, and the middle part 353 of the connecting guard plate 35 is located below the middle support platform 11 and has a gap between the middle support platform 11. After the two ends 351 / 352 of the connecting guard plate 35 are connected to the first support 31 and the second support 34, respectively, the stability of the first support 31 and the second support 34 can be improved, and it also has a protective function. For example, when the top plate 321 of the first telescopic support and the top plate 331 of the second telescopic support both fall accidentally, the connecting guard plate 35 can hold the middle support platform 11, thereby preventing the middle support platform 11 from falling accidentally.

[0043] refer to Figures 1 to 5 As shown, the gap between the middle portion 353 of the connecting guard plate 35 and the middle support platform 11 is 0.5-10 mm, preferably 1-5 mm, and more preferably 1-2 mm.

[0044] like Figures 3 to 5 As shown, the top heights of the two ends 351 / 352 of the connecting guard plate 35 are higher than the height of the middle portion 353, and the bottom surface of the middle support platform 11 is lower than the top heights of the two ends 351 / 352 of the connecting guard plate 35. This is equivalent to at least a portion of the other end of the middle support platform 11 being in a recess formed by the connecting guard plate 35.

[0045] In a preferred embodiment, if Figure 4 and Figure 5 As shown, the connecting guard plate 35 has a first top hole 354 and a second top hole 355, the top plate of the first telescopic support 32 passes through the first top hole 354, and the top plate of the second telescopic support 33 passes through the second top hole 355. Figures 3 to 7 As shown, the lower part of the top plate 321 of the first telescopic support 32 has a first flange 322, and the lower part of the top plate 331 of the second telescopic support 33 has a second flange 332. When the top plate 321 of the first telescopic support 32 is lifted into place, the first flange 322 contacts the bottom surface 356 of the connecting guard plate 35, and when the top plate 331 of the second telescopic support 33 is lifted into place, the second flange 332 contacts the bottom surface 356 of the connecting guard plate 35. Through this structure, the first flange 322 / the second flange 332 is lifted into place when it touches the bottom of the connecting guard plate 35, so that after each operation, the top planes of the top plates 321 and 331 are at the same height position, so that the position of the middle support platform 11 matched with the top plates 321 and 331 is kept at the same height, and no additional adjustment or correction is required.

[0046] like Figure 4 and Figure 5As shown, the top surface of the top plate 321 of the first telescopic support is square or circular, and the top surface of the top plate 331 of the second telescopic support is square or circular. Other similar structures are also possible, and other existing technologies can also be used. In addition, the structures of the first telescopic support 32 and the second telescopic support 33 are the same or different.

[0047] In any of the above embodiments, the other specific structures of the second retractable support 33 and the first retractable support 32 except the top plate 331 / 321 and the flange 332 / 332 can adopt various suitable existing technologies, such as a cylinder or an oil cylinder, etc. The utility model does not impose any special restrictions on them as long as they can complete their necessary functions.
