Description

Technical Field

[0002] Multi-wire saw is a device used for silicon wafer cutting. Silicon wafers are the main production materials in the semiconductor and photovoltaic fields. Silicon wafer multi-wire cutting technology is a relatively advanced silicon wafer processing technology in the world. It is different from traditional cutting methods such as saw blades and grinding wheels, and is also different from advanced laser cutting and inner circle cutting. Its principle is to use a high-speed steel wire to drive the cutting blade attached to the steel wire to rub the silicon rod to achieve the cutting effect. During the whole process, the steel wire is guided by more than a dozen wire wheels to form a wire net on the main wire roller, and the workpiece to be processed is fed by the lowering of the worktable. However, during the cutting process, due to the labor intensity problem, the steel wire may break for various reasons, which will lead to the interruption of the production process and the decline of product quality. If the wire breaks, the operator is often required to check and handle it on site, which not only increases the labor intensity, but also affects the work efficiency.

[0020] A group of wire sleeves 11 are provided on both sides of the rotating wire wheel 2. A plurality of wire sleeves 11 are provided and are equidistantly distributed corresponding to the wire grooves 8. Connecting arms 3 are connected to both sides of the inner wall of the mounting frame 1 by bolts. A fixing frame 5 is fixed to the bottom end of the connecting arm 3. The fixing frame 5 is fixed to the outer wall of the wire sleeve 11 at one end away from the connecting arm 3, thereby supporting the wire sleeve 11. A connecting block 15 is connected between every two wire sleeves 11 to improve the overall stability.

[0021] like Figure 3 As shown, an alarm 4 is fixedly installed on the top of the wire sleeve 11, and an infrared detector 14 is fixedly installed inside the wire sleeve 11.
