The clamping device includes a first clamping group 10 and a second clamping group 20 arranged side by side along a first direction.

[0039] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, the first clamping group 10 includes a first load platform 30 and a second load platform 40, and a clamping drive mechanism 70. The length directions of the first load platform 30 and the second load platform 40 are both along the first direction.

The second direction is perpendicular to the first direction and forms a horizontal plane with the first direction.

[0040] In an optional embodiment, the second clamping group 20 and the first clamping group 10 have the same structure. Figures 1 to 3 , Figure 5 and Figure 6 As shown, the second clamping group 20 includes a third carrier 50 and a fourth carrier 60, and a clamping drive mechanism 70 (the clamping drive mechanism 70 in the first clamping group 10 has the same structure, so the same reference numerals are used). The length directions of the third carrier 50 and the fourth carrier 60 are both along the first direction, and the fourth carrier 60 and the third carrier 50 are arranged side by side along the second direction. For the definition of side by side or parallel, reference can be made to the relative position relationship shown in the accompanying drawings.

[0041] like Figures 1 to 4As shown, a horizontal square silicon rod 02 is placed on the first carrier 30, a horizontal square silicon rod 01 is placed on the second carrier 40, a horizontal square silicon rod 04 is placed on the third carrier 50, and a horizontal square silicon rod 03 is placed on the fourth carrier 60. The length direction of the square silicon rods (01, 02, 03, 04) is along the first direction.

The top of the support body is generally cylindrical, and the middle of its top surface is concave. The purpose of doing so is mainly to prevent the square silicon rod 02 carried thereon from adhering to the first bearing surface 31 (because the surface of the square silicon rod 02 may be too smooth), so as to facilitate placement and transportation. In addition, although the figure shows 11 rows along the first direction and 2 rows along the second direction, it can also be 1 row or 3 rows, 4 rows (or 1 row, 3 rows, 4 rows), etc. along the second direction, and 5 rows, 7 rows, 9 rows, 4 rows, 15 rows, 20 rows, etc. along the first direction; in addition, various suitable existing technologies can also be used.

In addition, the driving unit 73 can also be other similar drivers or adopt various suitable existing technologies, such as oil cylinders or linear motors, lead screws, etc.

[0047] like Figures 1 to 7 As shown, the first connection seat 76 is pivoted to the lower part of the first swing arm 71 through the connection pivot 78, and the pivot axis is parallel to the rotation center line of the first swing arm 71; the second connection seat 77 is pivoted to the lower part of the second swing arm 72 through the connection pivot 79, and the pivot axis is parallel to the rotation center line of the second swing arm 72.

[0048] like Figures 1 to 7 As shown, five clamping drive mechanisms 70, the second clamping parts 33 and the third clamping parts 42 are arranged side by side in the first direction in the first clamping group 10; in addition, the number can be three, four, six, seven, ten, etc. The specific number is determined by the size of the material to be processed (the square silicon rod to be ground) and the size of the clamping part itself.

[0049] like Figures 1 to 3 , Figure 5 and Figure 6As shown, in the second clamping group 20, the third carrier 50 has a fifth clamping portion 52 and a sixth clamping portion 53 on both sides for clamping the square silicon rod 04, and the fourth carrier 60 has a seventh clamping portion 62 and an eighth clamping portion 63 on both sides for clamping the square silicon rod 03, and the seventh clamping portion 62 is adjacent to the sixth clamping portion 53.
