[0053] In order to better explain the present application, so as to be understood, the present application is described in detail by specific embodiments in combination with the drawings. In this paper, the orientation of the "upper", "lower" and other orientation terms is referred to the orientation of the drawings. Figure 1

[0054] Referring to Figures 1-7 , the silicon rod cutting device provided by the embodiment of the present application comprises a support frame 210, two first wheel sets 221 and two second wheel sets 222.

[0055] The two first wheel sets 221 and the two second wheel sets 222 are arranged on the support frame 210. The two first wheel sets 221 are arranged at intervals along a first direction of the support frame 210, and the two second wheel sets 222 are arranged at intervals along a second direction of the support frame 210. The second direction is perpendicular to the first direction.

[0056] The first wheel set 221 comprises at least four first wheel bodies 2211 arranged in a ring shape in a vertical plane and a first rectangular cutting ring line 2212 sleeved on the at least four first wheel bodies 2211. The second wheel set 222 comprises at least four second wheel bodies 2221 arranged in a ring shape in a vertical plane and a second rectangular cutting ring line 2222 sleeved on the at least four second wheel bodies 2221. The lower ends of the two first rectangular cutting ring lines 2212 and the lower ends of the two second rectangular cutting ring lines 2222 form a cross-shaped cutting end, and the cross-shaped cutting end is used for cutting the silicon rod A.

[0057] ​When the support frame 210 drives the two first wheel sets 221 and the two second wheel sets 222 to descend relative to the silicon rod A, the cross-shaped cutting end can contact the top of the silicon rod A to cut the four edges of the silicon rod A at the same time, improving the cutting efficiency, and the silicon rod does not need to be rotated multiple times, improving the alignment accuracy of the silicon rod and the cutting device, and thus improving the cutting accuracy. Furthermore, the cross-shaped cutting end formed by the lower ends of the two first rectangular cutting ring lines 2212 and the lower ends of the two second rectangular cutting ring lines 2222 is used to cut the silicon rod A, and the upper ends of the two first rectangular cutting ring lines 2212 and the upper ends of the two second rectangular cutting ring lines 2222 do not participate in cutting, which can avoid the upper and lower ends of the first rectangular cutting ring line 2212 and the second rectangular cutting ring line 2222 being forced at the same time, causing large deformation and breaking.

[0058] Further, at least four first wheel bodies 2211 in the first wheel set 221 include a driving wheel 2231, a driven wheel 2232, a tensioning wheel 2233, and at least one wire passing wheel 2234. At least four second wheel bodies 2221 in the second wheel set 222 also include a driving wheel 2231, a driven wheel 2232, a tensioning wheel 2233, and at least one wire passing wheel 2234. The driving wheel 2231, the driven wheel 2232, the tensioning wheel 2233, and the at least one wire passing wheel 2234 are all rotationally connected to the support frame 210.

[0059] The driving wheel 2231, the driven wheel 2232, the tensioning wheel 2233, and the at least one wire passing wheel 2234 are sleeved with cutting lines and correspondingly form the first rectangular cutting ring line 2212 and the second rectangular cutting ring line 2222.

[0060] Preferably, the first wheel set 221 and the second wheel set 222 each include one wire passing wheel 2234 to simplify the structure and facilitate installation.

[0061] Further, the support frame 210 is provided with a driving mechanism 240 connected to and driving the rotation of the driving wheel 2231, and a tensioning mechanism 250 connected to and driving the tensioning of the tensioning wheel 2233.

[0062] Specifically, the driving mechanism 240 includes a driving motor 241.

[0063] The driving motor 241 is arranged on the support frame 210, the output shaft of the driving motor 241 is connected to and drives the rotation of the driving wheel 2231 through a linkage mechanism, and the driving wheel 2231 drives the rotation of the first rectangular cutting ring line 2212 and the second rectangular cutting ring line 2222 through the driven wheel 2232, the tensioning wheel 2233, and the at least one wire passing wheel 2234.

[0064] Preferably, the linkage mechanism comprises a belt pulley fixedly connected to the output shaft of the driving motor 241, and a belt sleeved on the belt pulley and the driving wheel 2231. The driving motor 241 drives the belt pulley to rotate, and the belt pulley drives the driving wheel 2231 to rotate through the belt.

[0065] Specifically, the tensioning mechanism 250 comprises a tensioning motor 251 and a tensioning arm 252.

[0066] The tensioning motor 251 is arranged on the support frame 210, a horizontal output shaft of the tensioning motor 251 is fixedly connected to the tensioning arm 252, and an end of the tensioning arm 252 away from the tensioning motor 251 is rotationally connected to the tensioning wheel 2233. When the tensioning motor 251 drives the tensioning arm 252 to rotate around the horizontal output shaft, the tensioning arm 252 drives the tensioning wheel 2233 to synchronously rotate, so that the tensioning wheel 2233 tensions the first rectangular cutting ring line 2212 or the second rectangular cutting ring line 2222 sleeved thereon.

[0067] Preferably, each first wheel set 221 and each second wheel set 222 correspond to one driving mechanism 240 and one tensioning mechanism 250. Of course, it can also be arranged that two first wheel sets 221 correspond to one driving mechanism 240 and one tensioning mechanism 250, and two second wheel sets 222 correspond to another driving mechanism 240 and another tensioning mechanism 250. At this time, the two driving wheels 2231 in the two first wheel sets 221 are connected and synchronously rotated through connecting rods, and the two tensioning wheels 2233 are connected and synchronously rotated through connecting rods; the two driving wheels 2231 in the two second wheel sets 222 are connected and synchronously rotated through connecting rods, and the two tensioning wheels 2233 are connected and synchronously rotated through connecting rods.

[0068] Specifically, the main body of the tensioning motor 251 is arranged on the support frame 210 through a connecting frame, the output end of the tensioning motor 251 is fixedly connected to the tensioning arm 252, and an end of the tensioning arm 252 away from the tensioning motor 251 is rotationally connected to the tensioning wheel 2233 through a bearing. When the tensioning motor 251 drives the tensioning arm 252 to rotate around the horizontal output shaft, the tensioning arm 252 drives the tensioning wheel 2233 to synchronously rotate, so that the tensioning wheel 2233 can rotate around its own axis and rotate around the horizontal output shaft of the corresponding tensioning motor 251 arranged on the support frame 210.

[0069] Further, the two first wheel sets 221 and the two second wheel sets 222 are arranged in such a manner that the first rectangular cutting ring line 2212 is located inside the second rectangular cutting ring line 2222, or the first rectangular cutting ring line 2212 is sleeved on the outer periphery of the second rectangular cutting ring line 2222. In this way, there is a gap in the vertical direction between the first rectangular cutting ring line 2212 and the second rectangular cutting ring line 2222, so as to avoid contact and interference between the first rectangular cutting ring line 2212 and the second rectangular cutting ring line 2222.

[0070] Further, the silicon rod cutting device further comprises a pressing mechanism 230 for pressing the top of the silicon rod A.

[0071] The pressing mechanism 230 comprises a lifting rod 231 arranged on the support frame 210 and capable of lifting movement relative to the support frame 210, and a pressing head assembly 232 arranged at the bottom of the lifting rod 231. When the silicon rod A is not cut, the pressing head assembly 232 is lower than the cross-shaped cutting end.

[0072] In use: the support frame 210 drives the two first wheel sets 221 and the two second wheel sets 222 to descend relative to the silicon rod A until the pressing head assembly 232 is pressed against the top of the silicon rod A to clamp the silicon rod A. After the pressing head assembly 232 is pressed and drives the lifting rod 231 to move upward relative to the support frame 210, the support frame 210 continues to descend until the cross-shaped cutting end contacts the top of the silicon rod A and simultaneously cuts the four edge skins of the silicon rod A. Thus, the silicon rod A is clamped and positioned first and then cut.

[0073] Specifically, the pressing mechanism 230 further comprises a counterweight 233 arranged at the top of the lifting rod 231.

[0074] The counterweight 233 can drive the lifting rod 231 to descend relative to the support frame 210, so that the pressing head assembly 232 is lower than the cross-shaped cutting end when the silicon rod A is not cut.

[0075] Specifically, the pressing mechanism 230 is located at the center of the two first wheel sets 221 and the two second wheel sets 222 in the horizontal direction, so as to clamp the top of the silicon rod A corresponding to the center of the two first wheel sets 221 and the two second wheel sets 222 in the horizontal direction.

[0076] Further, the top of the support frame 210 is provided with a through hole 211 for accommodating and providing lifting movement of the lifting rod 231. The pressing head assembly 232 comprises a connecting plate 2321 fixed at the bottom of the lifting rod 231.

[0077] When the lifting rod 231 descends relative to the support frame 210, the counterweight 233 can abut against the top of the support frame 210; when the lifting rod 231 moves upward relative to the support frame 210, the connecting plate 2321 can abut against the bottom of the through hole 211. Thus, the two ends of the lifting rod 231 are limited during the lifting movement of the lifting rod 231 relative to the support frame 210.

[0078] Preferably, vertical sliding rails 234 are arranged on the outer periphery of the lifting rod 231, and sliding blocks 235 are arranged on the inner wall of the through hole 211 and slidingly connected to the vertical sliding rails 234; or,

[0079] Sliding blocks 235 are arranged on the outer periphery of the lifting rod 231, and vertical sliding rails 234 are arranged on the inner wall of the through hole 211 and slidingly connected to the sliding blocks 235.

[0080] The lifting rod 231 and the inner wall of the through hole 211 are connected by sliding rails and sliding blocks, so as to facilitate the lifting movement of the lifting rod 231 relative to the support frame 210, and improve the precision of the lifting movement of the lifting rod 231.

[0081] Preferably, an upper protective sleeve 212 is arranged on the upper wall of the top of the support frame 210 around the through hole 211, and a lower protective sleeve 213 is arranged on the lower wall of the top of the support frame 210 around the through hole 211. The upper protective sleeve 212 and the lower protective sleeve 213 are both used for protecting the vertical sliding rail 234. The upper protective sleeve 212 and the lower protective sleeve 213 are both preferably arranged as an organ protective sleeve.

[0082] Further, the pressure head assembly 232 further comprises a main pressure head 2322 and a secondary pressure head 2323 arranged on the connecting plate 2321.

[0083] The main pressure head 2322 is capable of pressing the center of the silicon rod A, and the secondary pressure head 2323 is capable of pressing the four edge skins of the silicon rod A. The main pressure head 2322 and the secondary pressure head 2323 are both capable of lifting movement relative to the connecting plate 2321, and the bottom of the main pressure head 2322 is lower than the bottom of the secondary pressure head 2323. The main pressure head 2322 and the secondary pressure head 2323 are sequentially pressed on the top of the silicon rod A and sequentially move upward relative to the connecting plate 2321.

[0084] In the process of pressing the top of the silicon rod A by the pressure head assembly 232, the main pressure head 2322 is first pressed on the center of the top of the silicon rod A, and then the secondary pressure head is pressed on the four edge skins of the top of the silicon rod A, so as to improve the pressing precision of the silicon rod A, and then keep the axis of the silicon rod A in a vertical state during the cutting process. Avoiding the top and bottom of the silicon rod A from being inclined due to processing errors, and at the same time pressing the silicon rod A to cause the axis of the silicon rod A to be inclined, affecting the subsequent cutting precision of the silicon rod A.

[0085] Preferably, the number of the secondary pressure heads 2323 is 4n, and n is an integer greater than or equal to 1. The 4n secondary pressure heads 2323 are arranged in a ring shape and are respectively used for pressing the four edge skins. More preferably, the number of the secondary pressure heads 2323 is 8, and the four edge skins are respectively pressed by two secondary pressure heads 2323, so as to increase the pressing force and improve the pressing stability, and can simplify the structure and facilitate the processing.

[0086] Specifically, the main pressure head 2322 and the secondary pressure head 2323 each comprise a sleeve 23241, a cover body 23242, a top rod 23243 and an elastic member 23244.

[0087] The sleeve 23241 is fixed on the connecting plate 2321 by bolts. The cover body 23242 is connected by welding or bolts and closes the top of the sleeve 23241. The top rod 23243 is located in the sleeve 23241 and is capable of lifting movement relative to the sleeve 23241. The elastic member 23244 is located in the sleeve 23241 and the two ends thereof respectively abut against the bottom of the cover body 23242 and the top of the top rod 23243.

[0088] When the support frame 210 drives the two first wheel sets 221 and the two second wheel sets 222 to descend relative to the silicon rod A, the top rods 23243 of the main pressing head 2322 and the auxiliary pressing head 2323 pressed against the top of the silicon rod A can drive the lifting rod 231 to move upward relative to the support frame 210 through the connecting plate 2321, at this time, the elastic members 23244 of the main pressing head 2322 and the auxiliary pressing head 2323 are all contracted, and the compression force of the elastic members 23244 forms the pressing force applied to the top of the silicon rod A through the top rods 23243.

[0089] When the cutting of the silicon rod A is completed and the silicon rod A leaves the pressing head assembly 232, the elastic members 23244 rebound and drive the top rods 23243 of the main pressing head 2322 and the auxiliary pressing head 2323 to return.

[0090] Specifically, the inner wall of the lower part of the sleeve 23241 extends radially inward to form an annular limiting body, and the top of the top rod 23243 extends radially outward and can abut against the annular abutment head on the annular limiting body to limit the downward position of the top rod 23243.

[0091] Further, in order to better explain and illustrate, the following is the cutting method of the silicon rod cutting device:

[0092] S1: When the silicon rod A is not cut, the pressing head assembly 232 is below the cross-shaped cutting end.

[0093] S2: The support frame 210 drives the two first wheel sets 221, the two second wheel sets 222 and the pressing mechanism 230 to descend relative to the silicon rod A.

[0094] S3: The main pressing head 2322 of the pressing mechanism 230 is pressed against the center of the top of the silicon rod A, and then the auxiliary pressing head 2323 is pressed against the four edge skins of the top of the silicon rod A. At this time, the elastic members 23244 of the main pressing head 2322 and the auxiliary pressing head 2323 are all contracted, and the compression force of the elastic members 23244 forms the pressing force applied to the top of the silicon rod A through the top rods 23243. The top rods 23243 of the main pressing head 2322 and the auxiliary pressing head 2323 pressed against the top of the silicon rod A drive the lifting rod 231 to move upward relative to the support frame 210 through the connecting plate 2321.

[0095] S4: The support frame 210 drives the two first wheel sets 221 and the two second wheel sets 222 to continue to descend, and after the cross-shaped cutting end contacts the top of the silicon rod A, the four edge skins of the silicon rod A are cut at the same time.

[0096] S5: when the silicon rod A cutting is completed, the support frame 210 drives the two first wheel groups 221, the two second wheel groups 222 and the pressing mechanism 230 to move upward synchronously, the elastic member 23244 rebounds and can drive the top rod 23243 of the main pressing head 2322 and the top rod 23243 of the auxiliary pressing head 2323 to recover.

[0097] Therefore, the silicon rod cutting device can conveniently and quickly cut the four edge skins of the silicon rod A at one time.
