Cart for protecting polycrystal small ingot corner

Abstract

The invention discloses a cart for protecting a polycrystal small spindle corner, wherein the cart is used for enabling silicon ingot to revolve and move in a workshop, and two baffles are arranged on a support panel of the cart at interval; a plurality of plane clapboards are arranged in the vertical direction between the baffles; the plane clapboards separate the space between the baffles into a plurality of accommodating spaces; a plurality of support frames are welded and fixed on the plane baffles at equal intervals; the surfaces of the support frames are provided with buffer layers; the support frames are of a hollow structure; the upper parts of the support frames are provided with isosceles trapezoids; and two trapezoids of each isosceles trapezoid on the upper part of the support frames serve as support inclined planes. The invention has the advantages that the cart for protecting the polycrystal small spindle corner is simple in structure and low in cost, can well protect the silicon ingot from being knocked in the processes of revolution and transportation, and ensures that the silicon ingot is loaded and unloaded conveniently and rapidly.

Description

technical field [0001] The invention relates to a trolley for protecting the edges and corners of small polycrystalline ingots during the turnover and transportation of workshops. Background technique [0002] At present, in the production process of silicon wafers for solar cells, the shape of the cast polycrystalline square is a cuboid with a square bottom. The physical properties of silicon materials are hard and brittle, and the corners are the most fragile parts, which are especially prone to bumps. Causes large edge chipping, even on the flat cart covered with buffer material, due to improper operation, it is very easy to bump during the process of lifting and putting down, resulting in scratches or edge chipping on the surface of the silicon ingot, and the defective rate of subsequent products It is also relatively high, and the sharp edges and corners after being broken are also likely to cause personal injury and inevitably cause certain losses.
