The cutting technology of the silicon single crystal rod is characterized in that a diamond wire with high strength is used, a well-shaped wire mesh structure is formed between a driving guide wheel and a driven guide wheel through different winding modes, then the silicon single crystal rod is driven to pass through a high-speed moving wire mesh, the well-shaped wire mesh cuts the round silicon single crystal rod into square silicon rods, and finally the square silicon rods are used for photovoltaic solar cell power generation. In the squaring process, when a round silicon rod is cut into a square silicon rod, a scrap of the silicon rod, called a "flaw-piece", is generated, and as shown in fig. 3, it is a cross-sectional view of the silicon rod after the squaring is completed. In the evolution course of working, the part of treating the processing and accomplishing the processing part of silicon rod will be guaranteed, moves along with the work material platform simultaneously, and the square silicon rod of accomplishing the processing part is pressed from both sides tightly by the workstation both ends, in order to avoid the corner silicon material "flaw-piece" that produces by buddha's warrior attendant wire-electrode cutting in the course of working, influences normal processing, now publishes a neotype single crystal silicon rod flaw-piece fixture, cliies "flaw-piece" in the course of working, guarantees that the processing of evolution goes on smoothly.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Referring to fig. 1 and 2, two groups of improved single crystal silicon rod flaw-piece clamping mechanisms are arranged in the same and opposite mode and are respectively arranged on a fixed working material table 13 and a movable working material table 14 of single crystal silicon rod squaring equipment. Each comprises a supporting arm 1, a linear motion driving structure and a chuck 7. The fixed working material table 13 and the movable working material table 14 are relatively provided with a fixed square rod jacking shaft 4 and a movable square rod jacking shaft 11.

Support arm 1 in every group has a plurality ofly, and divide and locate fixed square bar top mandril 4 and activity square bar top mandril 11 around, on support arm 1 one end was fixed in fixed work material platform 13 and activity work material platform 14, the other end connected linear motion mechanism. The fixture mounting seat 5 is connected with the linear motion mechanism, and a chuck 7 is arranged on the fixture mounting seat 5. The collet 7 is a non-metallic collet.
