Problems solved by technology

[0002] When the silicon rod cutting starts, the silicon block to be cut is placed on the diamond wire net in the middle of the two cutting rollers by the silicon block control device (processing table) set directly above the cutting rollers, starting from the starting coordinates set by the process At the beginning, silicon rods are vertically fed downward at a certain speed (table speed) for cutting. During the cutting process, the wire bow of the cutting line will change, which will affect the quality of crystal silicon cutting. In the past, manual inspection was used to intervene in the adjustment of the wire bow. The efficiency of artificial adjustment is low, and if the intervention is not timely, it will easily affect the quality of crystal silicon cutting. Therefore, it is of great significance to be able to invent a method for automatically adjusting process parameters

Embodiment 1

[0024] The method and equipment are suitable for the multi-wire cutting process of slicing. The multi-wire cutting device includes two horizontally distributed left and right cutting rollers. The cutting rollers have wire grooves and are covered with wire meshes. The wire meshes are made of gold steel wire. The gold steel wire enters the wire along the wire entry end of the left cutting roll, and the two main rolls are covered along the wire groove, and the wire exits from the steel wire outlet end of the right cutting roll. The gold steel wire enters from the incoming end, and after the outgoing end comes out, it is connected to the gold steel wire take-up and pay-off control device through a small guide wheel. , acceleration and deceleration and line tension; this program needs to have the functions of automatically collecting cutting information and automatically adjusting process parameters. Include the following steps:

Abstract

The invention discloses a method for automatically adjusting process parameters for cutting a single crystal silicon rod, which belongs to the technical field of crystal silicon cutting. The depth of the wire bow; modeling; adjusting the table speed according to the model can effectively improve the yield of crystalline silicon, reduce manual intervention, improve the cutting quality of crystalline silicon, save costs for enterprises, and have broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of crystalline silicon cutting, in particular to a method for automatically adjusting process parameters for cutting a single crystal silicon rod. Background technique [0002] When the silicon rod cutting starts, the silicon block to be cut is placed above the diamond wire web in the middle of the two cutting rollers by the silicon block control device (processing table) set directly above the cutting rollers, starting from the starting coordinates set by the process. At the beginning, the silicon rod is vertically fed downward at a certain speed (table speed) for cutting. During the cutting process, the wire bow of the cutting line will change, which will affect the cutting quality of crystalline silicon. In the past, the adjustment of the intervention wire bow was manually checked. The artificial adjustment efficiency is low, and the cutting quality of crystalline silicon is easily affected if the interve...
