Description
Technical field
The utility model relates to a kind of chemical surface treatment device, especially a kind of chemical surface treatment device of silicon chip of solar cell.
Background technology
When non-renewable energy resources such as electric power, coal, oil signal for help repeatedly, when energy problem became the bottleneck of restriction international community economic development day by day, more and more countries came into effect " sunlight program ", and the exploitation solar energy resources is sought the new power of economic development.Some high-caliber nuclear research institutions of Europe also begin to turn to regenerative resource.Under the promotion of international photovoltaic market great potential, the solar cell manufacturing industry of various countries falls over each other to drop into huge fund, enlarges to produce, to strive one seat.
Having in the manufacture of solar cells need be to the chemical treatment step on the single surface of cell silicon chip, and all is at present to reach the processing one side by the surface tension of adjusting chemical liquids, does not soak into other one side simultaneously.But this kind technology chemical liquids consumption is big, and has at cell silicon chip under the situation of warpage a little, can't carry out normal process.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, can realize only single surface being handled and not be subjected to the chemical surface treatment device of silicon chip of solar cell of the influence of its angularity.
The technical scheme that provides according to the utility model, the chemical surface treatment device of described silicon chip of solar cell, it comprises work nest, fluid reservoir, flowmeter, reclaim pump and charging valve, rotating turret is provided with some roller bearings between relative two cell walls of work nest, at roller bearing roller is arranged fixedly, be provided with shower nozzle at work nest, link to each other by input duct between the liquid outlet of fluid reservoir and the inlet of shower nozzle, be provided with flowmeter in input duct, offer back the liquid outlet at work nest, be provided with back the liquid import at fluid reservoir, the liquid outlet of returning at work nest links to each other by back liquid pipeline with returning between the liquid import of fluid reservoir, be provided with the recovery pump at back liquid pipeline, be connected with liquid-feeding tube at fluid reservoir, be provided with charging valve at liquid-feeding tube.
Described shower nozzle is flat, and the liquid spraying outlet of shower nozzle is positioned at the top ends of shower nozzle, and the liquid-inlet of shower nozzle is positioned at the bottom of shower nozzle, and the width of shower nozzle is gradually from the bottom up, and increase arranges.
The tank bottom height of described fluid reservoir is positioned on the trough floor of work nest, and the liquid outlet of fluid reservoir is opened on the tank bottom of fluid reservoir.
The utlity model has following advantage:
1, avoids the frequent adjustment of chemical liquids composition and the waste of the chemical liquids that causes and manpower;
2, effectively improve the influence of battery silicon warp degree;
3, saved the consumption of chemical liquids, reduced production costs;
4, the utility model is simple and reliable, and is easy to maintenance.
