Novel edge-collapse proof unfilled corner proof gripper for silicon crystal-bar slicer

Abstract

The invention relates to a novel clamp for preventing broken edge and broken corner used in a silicon stick section cutter. The clamp comprises two guide rails (6), four slide blocks (2), four baffle plates (1) and four staff gauges (4), wherein the two guide rails are arranged on the left and on the right respectively; the two ends of each guide rail (6) are fixedly mounted on the fragment box (10) of the section cutter. Every two of the four slide blocks (2) are sleeved on the two sides of every two guide rails (6); each slide block has an L-shaped section and consists of a transverse blockand a vertical block, wherein the transverse block is sleeved on and fixedly connected with the guide rail (6); the four baffle plates (1) are fixedly connected on the inner sides of the vertical blocks of corresponding slide blocks (2) respectively; the four staff gauges (4) are fixedly connected at the lower section of the inner side of corresponding baffle plates (1) respectively. When in cutting operation, the section cutter adopts a mechanical method to block the two end faces of the silicon stick so that the silicon stick can not extend sideways before being cut off, thereby ensuring that the silicon stick is cut off instead of breaking off, thus preventing broken edge.

Description

technical field [0001] The invention relates to a silicon crystal rod slicing machine, in particular to a novel clamp for a silicon crystal rod slicing machine with anti-collapse and corner-resistance. The invention belongs to the technical field of photovoltaic material processing. Background technique [0002] Edge chipping has always been a major problem in the silicon ingot slicing industry. No matter what type of slicer it is, a certain amount of edge chipping will occur during the silicon ingot slicing process. This has greatly affected the material utilization rate of silicon ingot slicing enterprises. The industry has put the solution to edge collapse in an extremely important position. [0003] The slicing principle of silicon crystal rod is as follows: figure 1 As shown, the steel wire 12 winds around one end of the guide wheel 13 from the pay-off wheel 11 through the line wheel I 14, then spirally winds to the other end on the two guide wheels, passes through ...
