Embodiment Construction

[0034] The core of the present invention is to provide a device that solves the problem of the quality of silicon ingots. Belly" phenomenon to ensure cutting quality. Another core of the present invention is to provide a method for solving the quality problem of silicon ingot breaking.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0036] After research, it was found that due to the substantial increase in the descending speed of the worktable and the increase in the tension of the steel wire, it did not match the cutting ability of the gold steel wire, resulting in the scraps of the silicon ingot being pushed outward during the cutting process of the steel wire. A slight deformation occurs, which causes the cutting trajectory of the steel wire to deviate from the vertical line, but at t...

Abstract

The invention discloses equipment for solving the squaring quality problem of a silicon ingot. The equipment comprises a tray (21), a protection block piece (22), a clamping baffle plate (24) and a position adjustment part (23), wherein the protection block piece (22) is fixed on the tray (21) and positioned at the periphery of the tray (21); and the two sides of the position adjustment part (23) are connected with the clamping baffle plate (24) and the protection block piece (22) respectively, so that the position of the clamping baffle plate (24) is changed, and the silicon ingot arranged on the tray (21) is clamped. The equipment for solving the squaring quality problem of the silicon ingot can prevent leftovers from being subjected to lateral deformation, so that the phenomenon that an edge silicon block is bulged is avoided and cutting quality is ensured on the basis of ensuring cutting speed and reducing cutting cost. The invention also discloses a method for solving the squaring quality problem of the silicon ingot.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a device for solving the quality problem of silicon ingot cube breaking. The invention also relates to a method for solving the quality problem of silicon ingot cube breaking. Background technique [0002] Silicon wafers are the main production material in the semiconductor and photovoltaic fields. Silicon wafer wire cutting technology is a relatively advanced processing technology in the world at present. [0003] Silicon wafer steel wire cutting technology uses a high-speed moving steel wire to drive the cutting mortar attached to the wire to rub against the silicon wafer, while the silicon wafer waits for the workpiece to be processed and the workpiece to be processed is fed through the lowering of the cutting machine table. , so as to achieve the cutting effect. [0004] For ease of understanding, the relevant terms are explained as follows: [0005] Polysilicon cube ...
