Description

Technical Field

[0001] The utility model relates to the technical field of square cutting machines, and more specifically to a back-blowing structure for square cutting machines. Background Art

[0002] In the field of photovoltaic power generation, common crystalline silicon solar cells are made on high-quality silicon wafers, which are cut from pulled or cast silicon ingots by multi-wire saws. Square cutting equipment is usually used to square the silicon rods so that the cross-section of the silicon rods forms a quasi-rectangular shape that can be used for slicing to obtain silicon wafers.

[0003] In the existing method of using the same cutting line to cut multiple silicon rods at the same time, the cutting line segment is too long. The longer cutting line segment is prone to uneven cutting line tension. The cutting line segments in different areas of the cutting line correspond to different tensions of the silicon rods to be cut, resulting in different cutting forces, cutting speeds, etc. for multiple silicon rods to be cut in a row, resulting in a decrease in cutting quality.

[0004] After searching, a Chinese patent with publication number CN212919962U discloses a silicon rod squarer. The squarer is configured by arranging a transition wheel between every two adjacent cutting wheel pairs in the wire cutting unit for guiding. A cutting line segment can be formed in the cutting wheel pair of each wire cutting unit. Each cutting line segment can cut silicon rods placed on at least two silicon rod supporting devices, thereby improving the utilization rate of the cutting line, increasing the proportion of the cutting line segment in the total length of the cutting line, and realizing simultaneous processing of multiple silicon rods.

[0005] However, when the above-mentioned square cutting machine is actually used, after the square cutting machine has cut the single crystal silicon rod, due to structural reasons, the upper side skin falls off and collides with the silicon rod, causing surface collapse of the crystal rod. At the same time, the single crystal silicon placed in the square cutting machine needs to be fixed through certain complicated steps, which is not convenient for subsequent cutting.
