Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silicon core cutting, in particular to a silicon core cutting device. Background Art
[0002] There are two existing methods for preparing silicon cores. One is the CZ method (melt zone pulling method), which is to heat a silicon rod of a certain diameter by high-frequency induction in a vacuum furnace filled with inert gas to partially melt the top of the rod, put a seed crystal of a certain diameter from the top, and then slowly pull it upward to make it into a slender silicon core with a diameter and length that meet the requirements. Its disadvantages are slow pulling speed, low production efficiency, high power consumption, large equipment investment, and high requirements for raw materials; the other is a diamond tool cutting method, which uses a CNC polysilicon silicon core multi-wire cutting machine tool or similar equipment with a diamond wire saw, and uses a thin steel wire wire electroplated with diamond particles to reciprocate or move unidirectionally at high speed on the workpiece to press a silicon rod of a certain diameter onto a wire net composed of diamond wires crossed by the machine tool, thereby cutting the silicon rod into a slender silicon core. This method has relatively low power consumption and high processing efficiency.
[0003] When cutting the silicon core, due to the shape characteristics of the triangular silicon core, it may have better optical or electrical properties. For example, the triangular silicon core may have lower reflectivity, higher light absorption efficiency, or better current transmission characteristics. However, the existing cutting devices mostly cut the silicon core into quadrilaterals, such as rhombuses and squares. Therefore, it is not convenient to optimize the shape of the silicon core, reduce the waste of raw materials, and reduce production costs. Utility Model Content
