A wire routing system for multi-wire cutting machine

Abstract

A steel wire passing system of a multi-wire cutting machine comprises a pay-off wheel, a pay-off guide wheel assembly, a groove wheel assembly, a take-up guide wheel assembly, a take-up wheel and a rack main plate and is characterized in that the pay-off guide wheel assembly is composed of a pay-off and wire arrangement mechanism, a pay-off tension wheel, a pay-off steering wheel and a wire inlet wheel, the pay-off and wire arrangement mechanism, the pay-off steering wheel and the wire inlet wheel are installed on the front side of the rack main plate, and the pay-off tension wheel is installed on the back side of the rack main plate; the take-up guide wheel assembly is composed of a take-up and wire arrangement mechanism, a take-up tension wheel, a take-up steering wheel and a wire outlet wheel, the take-up and wire arrangement mechanism, the take-up steering wheel and the wire outlet wheel are installed on the front side of the rack main plate, and the take-up tension wheel is installed on the back side of the rack main plate. According to the steel wire passing system of the multi-wire cutting machine, not only can the wire passing resistance of cutting wires be effectively reduced, the cutting speed be increased and the product quality be improved, but also the space occupation rate of the multi-wire cutting machine is reduced, and the system is more favorable for arrangement of production sites.

Description

technical field [0001] The invention relates to a multi-wire cutting machine, in particular to a wire routing system for a multi-wire cutting machine, belonging to the technical field of semiconductor material processing equipment. Background technique [0002] Multi-wire cutting is the most advanced slicing processing technology at present. Its principle is that the cutting wire (steel wire) passes through a set of grooved wheels to form a steel wire mesh with different pitches, and uses the high-speed reciprocating motion of the cutting wire to bring the abrasive into the processing area of ​​the material to be cut. Grinding is carried out, and the workpiece to be cut is fed vertically through the lifting of the worktable, so that the workpiece can be cut into several slices of required size and shape at the same time. [0003] The existing multi-wire cutting machine generally guides the cutting wire to the sheave assembly in the processing area of ​​the material to be cut...

AI Technical Summary

Problems solved by technology

[0003] The existing multi-wire cutting machine generally guides the cutting wire to the sheave assembly in the processing area of ​​the material to be cut through the pay-off guide wheel assembly for cutting, and then guides the cutting wire to the take-up wheel by the take-up guide wheel assembly to wind and collect. Since the number of guide wheels is an important factor affecting the cutting speed and the diameter of the cutting wire, the more the number of guide wheels, the greater the resistance of the cutting wire, the lower the maximum cutting speed, and the corresponding increase in the diameter of the cutting wire, which makes the workpiece The processing accuracy is reduced, so the existing multi-wire cutting machine has defects such as low production efficiency and difficult product quality assurance
