Cutting wire with composite structure, and manufacturing method and manufacturing equipment thereof

Abstract

The invention discloses a cutting wire with a composite structure, and a manufacturing method and manufacturing equipment thereof. The cutting wire comprises a plurality of bent parts and curve parts, wherein adjacent bent parts are connected through the curve parts. The method comprises the following steps of: processing a metal wire into a linear metal wire; unwinding the linear metal wire along a central axis, passing through a first limiting group wheel, winding on a first deformed guide roller, applying pulling force, and bending the metal wire; and making the bent metal wire pass through a guide wheel, and unwinding the metal wire along the central axis. In the equipment, an unwinding disk, the limiting group wheel, the guide wheel, the deformed guide roller and a winding disk are arranged in sequence. In the invention, a plurality of concave regions are formed in a three-dimensional space through a three-dimensional structure of the cutting wire, thereby mortar grinding materials can be wrapped and carried efficiently and are prevented from easily falling off from the cutting wire, so that the production speed and efficiency of the cutting and fragmenting processes of silicon materials, jewels and the like are greatly increased, and the surface quality of fragmented materials can be effectively improved.

Description

technical field [0001] The present invention relates to a cutting wire, its manufacturing method and manufacturing equipment, in particular to a composite structure cutting wire, its manufacturing method and manufacturing equipment. Background technique [0002] At present, in the division and slicing process of hard materials such as monocrystalline silicon and polycrystalline silicon in the fields of electronics and solar energy, and gemstones in the field of LEDs, the most used method is to use linear metal monofilaments, under a certain tension, one-way or reciprocating The way of movement is to achieve cutting and sharding. When the metal monofilament is moving, through the mortar transportation and injection system, before the metal monofilament contacts with the silicon rod and other objects to be cut, the mortar containing extremely hard abrasive particles is sprayed on the metal monofilament, and the metal monofilament is brought into the cutting process. Through t...

AI Technical Summary

Problems solved by technology

[0003] However, linear metal monofilaments can only be mechanically brought into mortar through a smooth surface during high-speed movement, and the ability to carry mortar is insufficient, which leads to the breakage of metal monofilaments when dividing hard materials such as silicon materials and gemstones. Silicon materials , Gemstones and other sliced ​​surfaces have line marks and other quality or process problems
