Multi-station annular wire saw cutting machine

Abstract

The invention relates to a multi-station annular wire saw cutting machine. The multi-station annular wire saw cutting machine comprises a base, a frame, a movable worktable, a lifting mechanism and acutting mechanism, wherein the cutting mechanism comprises a cutting frame and at least two cutting units; the cutting units are mounted on the cutting frame; the cutting frame is fixed on the liftingmechanism; the cutting units comprise wheel system mounting panels, guide wheel modules and annular diamond wire saws; the guide wheel modules are annularly arranged; the annular diamond wire saws are distributed in guide wheel wire grooves of the guide wheel modules; and the lifting mechanism is used for driving the cutting unit in a working state to cut silicon crystals. The multi-station annular wire saw cutting machine is simple in structure; multiple cutting units can selectively and independently perform the cutting work, so that the working process is safe, and the reduction of energyconsumption is facilitated; and the annular diamond wire saws are adopted to cut the silicon crystals, high in operation speed and cutting efficiency, simple in wire feeding after wire breakage and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of cutting hard and brittle materials, in particular to a multi-station circular wire saw cutting machine. Background technique [0002] Silicon material has become the main photoelectric material of solar cells. Usually high-quality silicon wafers for solar cells are cut from silicon ingots, and the length of the silicon ingots is relatively long, which is not suitable for direct slicing. Therefore, it is first necessary to use a cutting machine to process the silicon ingots to a specified length to It is convenient for follow-up work. [0003] In the Chinese patent literature, the publication number is CN205929109U, and the name is a polycrystalline three-knife cutting machine, which discloses a polycrystalline three-knife cutting machine, which includes a base, winding chambers installed on the left and right sides of the base, and winding chambers located on the left and right sides of the base. The cu...
