Special transportation-assisting trolley for cutting off single crystal silicon rods

Abstract

The invention relates to a special transportation-assisting trolley for cutting off single crystal silicon rods. The trolley comprises an underframe and a working platform, wherein a lifting device which is used for adjusting the height of the working platform is installed on the underframe, a pair of silicon rod supporting frames is fixed on two sides of the working platform, a silicon rod transmission is arranged between silicon rod supporting frames, and wheels are installed at the bottom of the underframe. By the aid of the technical scheme, the labor intensity of operators can be reduced greatly, losses of edge breakage during cutting of single crystal rods can be reduced or avoided, and particularly, losses caused by the fact that rods slip out of the hand and fall due to crystal rod collisions which often occur during transportation and cutting of large-diameter heavy-weight single crystal silicon rods can be avoided. The trolley has the advantages of being capable of greatly reducing the labor intensity of operators, reducing or avoiding losses of edge breakage during cutting of single crystal rods and particularly avoiding losses caused by the fact that rods slip out of the hand and fall due to crystal rod collisions which often occur during transportation and cutting of large-diameter heavy single crystal silicon rods.

Description

technical field [0001] The invention relates to a trolley for placing and transporting monocrystalline silicon rods, in particular to a special transportation auxiliary trolley for cutting monocrystalline silicon rods. Background technique [0002] The first process of processing single crystal silicon rods into single crystal silicon wafers is - cutting. The purpose of cutting is to cut off the head and tail of the single crystal silicon rod and the parts that do not meet the specifications required by customers, segment the single crystal silicon rod into lengths that can be handled by the slicing equipment, and cut the test piece to measure the resistivity of the single crystal silicon rod , oxygen content, minority carrier lifetime and other quality parameters. This work is done by a manually operated monocrystalline silicon rod cutting machine. [0003] Due to various reasons, the various types (styles) of monocrystalline silicon ingot cutting machines currently in us...

AI Technical Summary

Problems solved by technology

The monocrystalline ingot trolley with patent No. ZL201220040660.9 solves the above technical problems, but the effect is not good. It is still necessary to move the silicon ingot to the single crystal ingot trolley and then transport it to the destination. , the silicon rod is placed on the cart in an inclined state, which is not stable enough and easy to fall
