Embodiment Construction

[0021] The core of the present invention is to provide a multi-wire saw wire mesh system, which is used for silicon wafer cutting in the production process of solar cells. In the wire mesh system, the cutting wire is wound on the main roller to form a wire mesh. A cutting area and an adjusting area are formed on the main roller, the cutting area is used for the cutting process of the silicon wafer, and the adjusting area is used to adjust the width of the wire mesh in the cutting area to suit the silicon block or silicon rod to be cut.

[0022] In order to make those skilled in the art better understand the solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0023] The multi-wire saw wire mesh system disclosed in the present invention can be used in a free abrasive multi-wire cutting system, and can also be used in a diamond wire multi-wire cutting system.

Abstract

The invention discloses a multi-wire sawing wire net system. The multi-wire sawing wire net system comprises an unwinding reel, a winding reel, a main roller and cutting wires wound on the main roller, the cutting wires are formed into a wire net on the main roller, the wire net is divided into a cutting wire net surface and a non-cutting wire net surface, the cutting wires of one side of the cutting wire net surface are wound into a cutting area and at least one adjusting area in the groove of the main roller, the cutting wires on the adjusting area can be used for adjusting the width of the cutting area, so that reweaving is avoided each time when silicon blocks or silicon rods are replaced, consequently , the production time is saved, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of silicon wafer cutting, in particular to a multi-wire sawing wire mesh system. Background technique [0002] Today, with the depletion of fossil energy and the increasing greenhouse effect, solar energy has huge market potential as a sustainable and clean energy. Crystalline silicon cells dominate the solar cell market. [0003] Monocrystalline silicon wafers are widely used in the field of microelectronics or solar cells. They are single crystal rods made of silicon material by the Czochralski method. Silicon wafer, the cutting principle of multi-wire cutting machine cutting silicon wafer is: [0004] 1. Use steel wire as the carrier of mortar. The mortar is mainly composed of slurry mixed with SiC and cutting fluid. The mortar is fed into the nozzle by the feeding system of the slicer, and the mortar is sprayed from the nozzle and coated on the high-speed rotating steel wire belt. ; [0005] 2. Using...
