Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of bad cleaning product line of silk screen printing.
Background technology
Crystal silicon solar back of the body electric field, back electrode are positioned at rear surface of solar cell, form the back side and the bottom electrode of silion cell.Match with the upper electrode on silion cell surface, play the effect that the electric energy that silicon solar cell produces is sent to the external world, anelectrode and back electrode and formed by printing, drying, sintering by aluminium paste by silver slurry, back electrode.
In normal cell piece silk screen printing production process; some silk screen printing substandard products caused owing to printing exception often occur, these substandard products mainly have that front description is imperfect, back side figure is imperfect, back side aluminium paste has drained to the front or side etc. of cell piece.All these printing substandard products are once through drying, after sintering, and the slight substandard products such as become, serious directly can produce waste product, thus having influence on final conforming product rate and conversion ratio.
Processing method to cell piece silk screen printing substandard products is that artificial water is carried out or rinses at all at present, and efficiency is low, weak effect, is unfavorable for the production needs of industrialization.
Utility model patent if notification number is CN203536461U discloses a kind of workbench for wiping silk screen printing substandard products, including desktop, arrange on the table for place and adsorb printing substandard products hollow table top, for supporting desktop support and for make in table top produce negative pressure so that adsorb printing substandard products vacuum pump, the panel of described table top is provided with multiple aperture, described table top base plate is provided with through hole, and described through hole is connected with vacuum pump by flexible pipe.When adopting this workbench wiping silk screen printing substandard products, silver slurry is not easy to be stained with on left handed gloves, and convenient silver slurry reclaims；And the fixing ratio of silicon chip is stronger, improves work efficiency.This patent adopts pure manual cleaning method, has cleaning efficiency low, and weak effect is unfavorable for the production needs of industrialization.
And for example notification number is that the patent of invention of CN102437234B discloses a kind of solar battery sheet printing and does over again the processing method of substandard products, solar battery sheet of doing over again carries out ultrasonic waves for cleaning, first time washing successively, hot hydrochloric acid cleans, second time is washed, dried and re-start silk screen printing, it solves the solar battery sheet after existing printing and can not effectively do over again the problem processed and cause the wasting of resources, cost increase.But it does not relate to the equipment that cell piece cleans, and cannot realize the cleaning of automatization yet, have cleaning efficiency low, weak effect is unfavorable for the production needs of industrialization.
