[0002] Crystal rods are a common solid material, usually in rod shape. They are made of single-crystal materials and have a highly ordered crystal structure. Crystal rods are a material used in semiconductor manufacturing. The production process of crystal rods usually requires grinding. However, the existing grinding equipment has significant defects in the way crystal rods are fixed. It relies solely on the cooperation of grinding rollers and extrusion rollers to clamp the crystal rods. This clamping method is difficult to achieve ideal results. During the grinding process, if disturbed by external factors such as uneven grinding force or equipment vibration, the crystal rods are very prone to displacement. Moreover, the frequent displacement of crystal rods not only increases the defect rate, but also requires operators to stop the machine frequently for adjustment, which seriously affects production efficiency.
