Description

Technical Field

[0001] This utility model relates to the field of clamping mechanisms, specifically to a single crystal rod clamping mechanism. Background Technology

[0002] A single crystal rod is a silicon single crystal rod manufactured through a specific process. It features high purity, high crystal quality, and uniformity, and is widely used in the semiconductor industry and other high-tech fields. During the cutting process, a clamping device is required. For example, patent application number 201120512763.6 discloses a clamping device for cutting silicon single crystal rods, including a groove and two clamping blocks. The groove has a recessed area containing a screw rod. One end of the screw rod extends to the outside of the groove and has a knob at that end. The portion of the screw rod located within the recess consists of two sections with opposite external threads. The bottom of each clamping block has a through hole with internal threads, which is threaded to the two screw rod sections. Nuts are provided on the screw rods on the outside of the two clamping blocks. It has the following advantages: simple structure and easy to use. It is used to fix the main body when cutting silicon single crystal rods, so that the single crystal rod is subjected to more uniform force and the fixation is more reliable and firm. This reduces or avoids edge chipping when silicon single crystal rods, especially large-diameter silicon single crystal rods, are cut.

[0003] However, the patent still has the following drawbacks: because the clamping device does not have a component that facilitates the disassembly of the clamping block, the entire clamping device can only clamp single crystal rods of the same size, which limits its use. Utility Model Content
