Description

Technical Field

[0001] The invention relates to a rope loop production technology, in particular to a rope loop of an ultra-fine jointless rope loop production device. Background Art

[0002] Solar panels are made of monocrystalline silicon or polycrystalline silicon. The silicon ingot produced by polycrystalline silicon is a whole cubic material. Monocrystalline silicon is produced as a cylindrical rod. To process into a square solar panel, it is necessary to cut, cut, trim and round the edges. The circular diamond wire saw is an important consumable used in the cutting and squaring processes.

[0003] The circular diamond wire saw is a circular steel wire with a diameter of 0.3-0.4 mm and a length of 3-5 meters. Diamond powder and nickel are attached to the surface of the circular steel wire by electroplating deposition. It is used to cut hard and brittle materials, such as jade, agate, sapphire, etc. In the field of photovoltaic power generation and semiconductors, it is mainly used for squaring silicon ingots, trimming silicon rods, and cutting.

[0004] The production method of this ultra-fine ring wire rope is to cut a 1+6 (1 inside and 6 outside) wire rope to the specified length, and then stagger each wire by 0.5 meters and re-weave it to form a ring. The main disadvantage of this ring wire rope is that there are too many ends of the single wire. Even if it is electroplated with a layer of nickel, it is inevitable to produce warping during the cutting process. Once the warping occurs, scratches or short lines will immediately appear on the cutting surface. In addition, this method is purely handmade, with a long production cycle, and the product quality is affected by the workers' proficiency. Summary of the invention
