Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting machines, and more specifically to a first-line anti-collision device for cutting machines. Background Art
[0002] Cutter, also known as cutting machine, is a key equipment in the field of semiconductor material processing. It is mainly used to accurately cut semiconductor materials such as silicon crystal rods as needed. In this process, it is crucial to ensure the precise positioning of the crystal rod, otherwise it may cause equipment damage, production interruption, and even pose a safety threat to the operator. In the operation of the cutter, a core link is the calibration of the crystal rod position, which is the so-called "first line" confirmation. The first line represents the exact position of the crystal rod in the cutter. If this position calibration is inaccurate, it will lead to errors in the cutting process. In extreme cases, it may cause a collision accident, seriously damaging the cutter's tool and the crystal rod itself, and may even cause harm to the operator.
[0003] However, in actual operation, engineers found that even if the first-line data appeared normal in the system, the actual position of the crystal rod would sometimes still have a large deviation. This situation may be caused by various factors such as slight deformation of mechanical parts, sensor accuracy problems or limitations of the system control algorithm. After the deviation occurs, the crystal rod is prone to collision with the machine. Therefore, it is necessary to design an anti-collision device to address this problem. Utility Model Content
