Abstract
Description
Technical Field
[0001] The utility model belongs to the field of photovoltaics, and particularly relates to a measuring tool for quickly finding the angle of a wire network. Background Art
[0002] In the photovoltaic silicon wafer slicing industry, in order to reduce the production cost of a single wafer, various companies are constantly exploring the path of thinning and thinning. As silicon wafers become thinner and thinner, the steel wire used for cutting becomes thinner and thinner. During the silicon wafer cutting process, the steel wire is very unstable in the main roller groove, resulting in excessive TTV and line marks on the silicon wafer surface, affecting the cutting quality. The industry increases the lateral force by tilting the wire mesh to make the steel wire more stable in the groove, reducing the TTV and line marks on the silicon wafer surface, but it also means that the slope must be controlled within a certain range to keep the yield the most stable. Deviating from this range will bring other abnormalities. How to find the correct wire mesh angle is a problem faced by major slicing manufacturers.
[0003] There are two existing methods for finding the slope of the wire mesh:
[0004] 1. The earliest method in the industry was the measurement method. When weaving the wire mesh, the first main roller entering the wire mesh was used as the reference zero point, and the other parallel main roller was used as the movable end. After the wire mesh was woven, the end face of the bearing box close to the wire mesh was used as the zero point to measure the distance between the two parallel main rollers and the wire mesh. The two distances were then subtracted. When the result was greater than or less than ±0.5mm, the movable end wire mesh was adjusted until the result was equal to ±0.5mm. This was very time-consuming and had low accuracy.
[0005] 2. The common method in the current industry is the groove counting method. When weaving the wire mesh, any groove on the first main roller entering the wire mesh is used as the reference zero point, and another parallel main roller is used as the movable end to weave the entire wire mesh at the same number of grooves, 3 grooves in front or behind as the starting point of the other side of the wire mesh. Although this method is faster than the first method, as the groove pitch becomes smaller and the starting end of the groove is farther away from the end face of the main roller, it becomes increasingly difficult to accurately confirm the number of grooves, and the number of grooves gradually loses accuracy, causing losses.
