The specific operation flow is as follows:

1) firstly, the polycrystalline silicon ingot is conveyed to a silicon material platform, which can be manual or automatic mechanical arm. The polysilicon ingots are placed on the cushion blocks of the silicon material table, the number of the cushion blocks is generally three, the polysilicon ingots are roughly leveled through the cushion blocks, and one vertical end face of each polysilicon ingot leans against the edge of the movable clamping block 1913 of the movable clamping assembly 191 as much as possible. The cylinder of the movable clamping assembly 191 acts to push the polysilicon ingot through the movable clamping block 1913, thereby clamping the polysilicon ingot. At this time, the movable clamping assemblies 191 and the fixed clamping assemblies 192 which are arranged in one-to-one opposite mode are provided, so that clamping of the polycrystalline silicon strip block can be always kept after cutting is completed, and broken lines caused by edge breakage and shaking are reduced.

2) The strip cutting mechanism 1 operates to cut the strip. The driving mode of the strip and block cutting running mechanism is greatly different from the previous driving mode, because the size of the cut polysilicon block is generally 158mm multiplied by 158mm, the size is limited by space, and the driving mode adopts a synchronous belt for conveying. The cutting operation assemblies 182 are provided with a plurality of cutting operation assemblies 182, each cutting operation assembly 182 is provided with an independent driving feeding mechanism, 2 sets of cutting units are arranged on the cutting operation assemblies 182, the distance between the cutting units is 158mm, therefore, in the step, the polycrystalline silicon ingot is cut into a plurality of strips with the thickness of 158mm, and the leather materials on the other four surfaces of the strips are kept in the original state.

3) After the first cutting mechanism finishes cutting, 2 leather materials on the outermost side are manually collected, and then the strip cutting mechanism 1 retracts to the initial position. The strip materials are respectively circulated to the strip material placing rack for standby through the strip material transferring mechanism 3 and the strip material conveying mechanism 2. The clamping mechanism of the hoisting assembly 23 on the bar material conveying mechanism 2 acts in sequence to clamp the bar material to the block material cutting mechanism 4 respectively, the positioning block of the block material cutting mechanism 4 realizes rough positioning on one end of the bar material, the movable clamping block 424 acts to clamp the bar material together with the fixed clamping block 426, and because the two clamped surfaces of the bar material are cut surfaces, the shape and position precision can be ensured, the block material cutting is completed under the clamping of the movable clamping blocks 424 and the fixed clamping block 426, at the moment, after two times of cutting, the size of the polycrystalline silicon block material is 158mm × 158mm generally. The block clamping mechanism 42 has two stations, one station is in a cutting state, and the other station can carry out unloading or loading, so that the efficiency is effectively improved.

4) The above work is completed and the block can be transferred to the next process either manually or by a robot. In the next process, the polycrystalline silicon block needs to be manually subjected to crystal orientation detection, mark lines to be cut are marked at two ends of the block material, the block material is transferred to a production line, the block material is grabbed through the previously designed equipment, and head and tail leather materials are cut off, so that a blank with six surfaces all subjected to cutting is obtained.

5) The cutting method comprises the following steps: the method comprises the steps of placing a silicon ingot on a first workbench, cutting the silicon ingot by a first cutting mechanism to form a plurality of strip materials, transferring the strip materials to a bottom two workbench, cutting the strip materials by a second cutting mechanism to form a plurality of block materials, manually marking mark lines on the block materials, and cutting the block materials from the mark lines.
