Definitions

  • the present invention relates to a method for manufacturing an endless cutting wire for cutting ingots, which consists of a single cutting ring used for cutting silicon ingots grown in single crystal or polycrystal and forms one connection ring without interruption while rotating the ingot at high speed on a pulley.
  • Wafers used as core parts of semiconductors and solar cells are manufactured by cutting silicon ingots. In the past, it was common to use a saw-cut band-type cutting blade as a cutting means. Due to the high blade breakage rate and short life span, the economy is not good enough.
  • dozens of small-diameter small diameter wires are twisted like pretzel to form several strand wires (S) having a larger diameter.
  • the strand wire (S) is again twisted into a large diameter rope-shaped wire, but has an integral continuous ring structure connected endlessly as a whole without interruption, while cutting means (carbide grains or diamond grains) are formed on the surface thereof. )
  • cutting means carbbide grains or diamond grains
  • the conventional ingot cutting wire for cutting ingots is a method for achieving an endless structure in which the whole is integrally connected without a break, and welds or separates the one end and the other end of the wire to each other. It's taking a way to squeeze the connecting clip of
  • connection part is weak, so that the wire is easily rotated when the high speed rotation is performed for the ingot cutting while the pulley is wound. There was a problem acting as a cause of break.
  • cemented carbide particles fixed to the cutting wire are also conventionally various fixing methods have been proposed, but the fixing force is weak or brittle, there is a problem that falls well when friction with the ingot material, productivity and cutting quality is poor There have been problems such as deterioration.
  • the present invention was created to solve the problems caused by the conventional endless cutting wires as described above, so that the entire length of the cutting wire has no weak connection parts or knots as in the prior art, so that it has a seamless endless connection without disconnection.
  • the technical task is focused on providing a new method of manufacturing endless cutting wire.
  • the present invention prepares at least seven strands of the same length of strand wire (S) made by twisting a small diameter dozens of small diameter wires of a predetermined thickness as shown in FIG. 1,
  • the prepared seven or more strand wires (S) are again kneaded and twisted by another wire rope (R) having a larger diameter, and the twist start point and the opposite twist end point of the seven strand wires (S) are twisted at different positions, respectively.
  • the method for manufacturing the endless cutting wire for cutting the ingot according to the present invention as described above does not generate any vulnerable connections or knots in the entire cutting wire of a certain length connected integrally as opposed to the unity, and maintains solid integration connectivity. Therefore, there is a significant advantage that it is possible to maintain a solid state without cutting or boiling at high speed for cutting in the tight winding state between the pulleys, and furthermore, the preferred cemented carbide fixing method disclosed herein has a firm fixing property on the cutting wire.
  • the cutting force can be improved while the elastic force for increasing cutting efficiency is appropriately used, which not only helps to improve cutting quality but also greatly contributes to preventing damage such as dropping of cemented carbide beads. Invention.

  • Dozens of small diameter wires are twisted like a pretzel to form several strand wires (S) of larger diameter, and the formed strand wires (S) are twisted into rope-shaped wires of large diameter again, but without being unbroken. It has an endless ring connected to one end, while cutting means 20 (carbide grains or diamond grains) are fixed to the surface of the rope-type wire, so as to be highly efficient ingot cutting means when it is wound tightly between high speed rotating pulleys.
  • cutting means 20 are fixed to the surface of the rope-type wire, so as to be highly efficient ingot cutting means when it is wound tightly between high speed rotating pulleys.
  • Each twisted end point of the strand 7 stranded strand (S) is also twisted while being tightly wrapped in the other strand wire in the process of twisting each other in the center of the stranded wire so that the twisting proceeds, the weak part (cut, knot) Manufacturing endless cutting wires connected in series with and without;
