Solar silicon wafer wire cutting guide roller and manufacturing method and special film coating machine and electroplating machine

Abstract

The invention relates to a solar silicon wafer wire cutting guide roller and a manufacturing method and a special film coating machine and an electroplating machine. the method comprises the following steps of: making a V-shaped guide roller base body made from composite polyurethane, plating a metal composite layer on the surface of the V-shaped guide roller base body, and plating a wear-resistant composite layer on the surface of the metal composite layer,wherein the metal composite layer is compounded by one or more then one of nickel, titanium, copper and chromium, the wear-resistant composite layer is a antiseize polymer in which wear-resistant particles are contained. According to the invention, under the condition of not changing the existing cutting technique, the service life of the V-shaped guide roller manufactured by the invention is prolonged, the replacement frequency can be reduced, the cutting yield is stabilized, the equipment utilization ratio is improved, and the overall cutting cost is lowered.

Description

technical field [0001] The invention relates to the technical field of solar silicon wafer cutting equipment, in particular to a solar silicon wafer wire cutting guide roller, a manufacturing method, a special coating machine and an electroplating machine. Background technique [0002] China's photovoltaic power generation industry has developed rapidly in the past five years, and the investment in solar silicon wafer cutting equipment has been put into operation by dozens of times in recent years. Among them, the V-shaped wire rollers used for cutting steel wires are consumed in large quantities with the expansion of the slicer. , Among them, the surface wear and wear resistance characteristics of the V-shaped wire roller directly affect the quality of the slice, the utilization rate of the equipment and the comprehensive wire cutting cost. [0003] In the process of wire cutting of solar silicon wafers, the whole mechanism is to use the hard characteristics and sharp water...

Problems solved by technology

[0004] With the development of the entire solar energy industry, composite polyurethane elastomer guide rollers are widely used in solar silicon wafer wire cutting. Because the wear resistance of its surface is affected by the material structure of the polymer, the actual service life cycle is between 150-200 hours. Unstable slice quality has been caused

Replacing guide rollers during the production process is a very complicated job, and it takes 5-8 hours for professional operators to replace them, which also means that the company needs to stop for 5-8 hours, resulting in waste of other machine equipment resources. It also needs to clean other equipment, and the surface repair will increase the cost of the enterprise and increase the labor intensity of the workers. The whole industry is working on how to improve the surface wear resistance and service life of the V-shaped steel wire guide roller, improve the utilization rate of the machine, and reduce the cutting cost. Find a new way without changing the manufacturing process of the existing cutting guide roller
