If new laser cutting machine equipment of 3D concave surface is developed, the required cycle is long and the cost is high. Meanwhile, because of the fact that the 3D concave-convex glass plate is a non-planar product, although the existing single-line cutting machine air suction base is provided with a groove matched with the product, the product is embedded in the groove and is fixed through vacuum air suction, due to factors such as vibration of a machine table and processing errors of the base, air leakage exists in the base of the middle-piece product in the cutting process, and the middle-piece product is directly separated from the base when the middle-piece product is partially cut into small pieces of products, so that waste breakage and poor size are caused. Because of the diamond wire of the single-wire cutting machine is transversely cut, the clamp needs to be manually turned midway during the processing of the middle piece, so that the middle piece product on the clamp is transversely and longitudinally cut, the middle piece is processed every time, and when the product clamp is re-installed and positioned again, the machine needs to be re-debugged, which is not only tedious and low in efficiency. Moreover, the single wire cutting machine needs to cut the middle piece into single keys for three or more hours at present, and the biggest problem is that the cutting efficiency is low, the rejection rate of the cut pieces is high, and how to improve the cutting efficiency and the yield of the cut pieces becomes the biggest difficulty.
Therefore, there is a need for a new technique for a non-planar key separation device.
