Technical Field

The utility model relates to an ingot overturning mechanism with a lifting function, and belongs to the technical field of ingot separation processing.

Background

As is well known, ingot cutting is a method of making wafer slices, including saw blade cutting, diamond cutting, laser cutting, and the like. The wafer is easy to crack by cutting with a saw blade, and the method requires that the thickness of the wafer is more than 2mm and the wafer smaller than 2mm is easy to crack, so that great material waste is caused; the loss rate of cutting by the multi-wire cutting machine adopting the diamond cutting wire is up to more than 50%, and when the diamond wire saw is used for cutting the ingot, not only is up to 40% of the ingot turned into waste materials in the form of dust, but also the wafer yield is directly caused to be low, the cutting process of a single wafer can be completed in nearly several hours, and the time cost is seriously increased. Therefore, the problems existing in other methods can be effectively avoided by adopting the laser cutting, and the corresponding mechanical method is adopted after the ingot is cut by the laser, so that not only can the stress still existing in the ingot be eliminated, but also the wafer slices can be rapidly separated. However, the processing technology related to laser cutting has certain specific requirements, the vertical position relationship of the ingot after being separated into a wafer sheet and a secondary thick ingot needs to be accurately adjusted, and the occupied area of equipment is not too large, so that the space utilization rate of the equipment can be improved, the research and development cost is reduced, and the use and maintenance convenience is improved.

Therefore, we provide an ingot turning mechanism with a lifting function, which can realize the turning of an ingot in a very small range space, and can enable the position of the ingot to be moved to a material waiting position of a next working procedure step, thereby meeting the requirement of equipment on the laser processing working procedure step, reducing the occupied area of the equipment and improving the space utilization rate and the use convenience.
