Abstract

The invention provides a cylindrical silicon rod clamp, aiming at solving the problem that more inferior-quality products of silicon wafers are produced when an existing cylindrical silicon rod clamp is used for clamping a silicon rod. The cylindrical silicon rod clamp comprises a fixing device and a positioning device, wherein the fixing device comprises a lower pressing block provided with four guiding columns; a thread is arranged at the upper part of each guiding column; the fixing device further comprises a lower module, an upper module, an upper pressing block and four pressing nuts; an upper arc-shaped groove is formed in the lower surface of the upper module and a lower arc-shaped groove is formed in the upper surface of the lower module; the positioning device comprises a rotary connection device, a bracket, a sliding rod and an adjusting bolt; the sliding rod is arranged on the bracket in a penetrating manner and is provided with scales; a stopping block is arranged at each of the left and right ends of the sliding rod; the sliding rod is sleeved with a spring. The cylindrical silicon rod clamp is provided with the positioning device and the fixing device of a silicon rod, so that the silicon rod is convenient to position and fix; the commonality is strong; the positioning device can be used for more accurately positioning the silicon rod; the thickness error of the silicon wafers is reduced and the quality of the silicon wafers is improved.

Description

Technical field [0001] The invention relates to a cylindrical silicon rod clamp. Background technique [0002] When cutting a cylindrical silicon rod into silicon wafers, it is necessary to use a clamp to position and fix the silicon rod; when the existing cylindrical silicon rod clamp uses a claw to clamp the silicon rod, it is easy to produce pressure on the surface of the silicon rod. Marks affect the quality of the product; when the upper and lower arc plates are used to clamp the silicon rods, the clamps or the surface of the silicon rods are not smooth and other defects will cause the clamping of the silicon rods to be unstable. The product quality is affected; in addition, the arc-shaped plate can only hold silicon rods of one diameter with a single performance; and most of the existing cylindrical silicon rods have no positioning device, and the thickness of the produced silicon wafers is uneven. Summary of the invention [0003] The invention provides a cylindrical silic...
