Description

Technical Field

[0001] This utility model relates to the field of monocrystalline silicon production technology, specifically a monocrystalline silicon rod transfer device. Background Technology

[0002] Monocrystalline silicon is a relatively reactive non-metallic element and an important component of crystal materials. It is at the forefront of new material development and its main uses are as a semiconductor material and for solar photovoltaic power generation and heating. Monocrystalline silicon rods are formed in a furnace by zone melting or Czochralski processes. They are silicon single crystal rods in which silicon atoms are rearranged according to the lattice arrangement direction of the seed crystal. A turnover cart is required during the turnover of monocrystalline silicon rods.

[0003] Monocrystalline silicon rod turnover carts are used to transfer monocrystalline silicon rods to different production processes. Most of the existing monocrystalline silicon rod turnover carts have fixed-size clamp frames that cannot be adjusted. They can only be used for monocrystalline silicon rods of the corresponding size, resulting in a small range of applications and low adaptability. Moreover, when tightening, it is necessary to press down by hand and then tighten it with an external nut, which is time-consuming and laborious. Not only is the tightening efficiency low, but the nuts are also prone to loosening, resulting in low firmness. Utility Model Content
