A single crystal silicon rod slicing device

Abstract

The invention discloses a monocrystalline silicon rod slicing device, the structure of which comprises a distribution box, a cutting head, an introduction device, a processing table, a fixing seat, and a base. The head is matched with the introduction device, and the beneficial effect of the present invention is that when the sandwich layer on the clamp head is in contact with the monocrystalline silicon rod, the magnetic properties of the two magnetic blocks are different, and the mutual attraction strengthens the clamping force of the clamp head , under the double function, the clamping head can clamp and fix the single crystal silicon rod, and the two movable grooves can be pushed out and replaced according to the diameter of the single crystal silicon rod and adapted to the size of the single crystal silicon rod. When the first movable slot and the two fixed slots are on the same arc, stop the outward movement, and at the same time apply force to the single crystal silicon rod, so that the single crystal silicon rod is fixed, thereby preventing the single crystal silicon rod from being impacted by the wire saw. Displacement occurs to ensure that the position of the single crystal silicon rod is relatively fixed during processing, and further guarantees the slice quality of the single crystal silicon rod.

[0003] The existing monocrystalline silicon rod slicing device realizes the slicing of monocrystalline silicon by placing the single crystal silicon rod on the processing table and pushing it forward, and in the process of slicing, the process of operating the single crystal silicon rod In this process, the single crystal silicon rod is subjected to a certain impact force, and the shape of the single crystal silicon rod is similar to a cylinder. Under the double action of the impact force and its own shape, relative displacement is prone to occur during the operation, which affects the quality of the slice.
