Description
Technical field
The present invention relates to mechanical field, more particularly to a kind of bad cleaning device of silk-screen printing and its cleaning method.
Background technology
Crystal silicon solar back of the body electric field, back electrode are located at rear surface of solar cell, form the back side and the bottom electrode of silion cell.
It is engaged with the Top electrode on silion cell surface, plays the effect that the electric energy for producing silicon solar cell sends the external world to, positive electricity
Pole and back electrode are formed by silver paste, back electrode by aluminium paste by printing, drying, sinter.
In normal cell piece silk-screen printing production process, often occur some due to silk caused by printing exception
Wire mark brush substandard products, these substandard products mainly have that front description is imperfect, back side figure is imperfect, back side aluminium paste has drained to cell piece
Front or side etc..All these printing substandard products are Yi Dan after drying, sintering, and slight turning into waits substandard products, and serious is straight
Waste product can be produced by connecing, so as to have influence on final product qualification rate and conversion ratio.
The processing method to cell piece silk-screen printing substandard products is manually to be cleaned or rinsed with water at all at present, efficiency
Low, effect is poor, is unfavorable for the production needs of industrialization.
A kind of be used for wiping silk-screen printing substandard products is disclosed such as the utility model patent that notification number is CN203536461U
Workbench, including desktop, setting are used to place and adsorb to print the hollow table top of substandard products, for supporting desktop on the table
Support and for making to produce negative pressure in table top and then adsorbing the vavuum pump of printing substandard products, the panel of the table top is provided with
Multiple apertures, the table top bottom plate is provided with through hole, and the through hole is connected by flexible pipe with vavuum pump.Wiped using this workbench
When wiping silk-screen printing substandard products, silver paste is not easy to be stained with left handed gloves, facilitates silver paste to reclaim；And silicon chip fixation is than stronger,
Improve operating efficiency.The patent uses pure manual cleaning method, and low with cleaning efficiency, effect is poor, is unfavorable for industrialization
Production need.
The patent of invention that and for example notification number is CN102437234B discloses a kind of solar battery sheet and prints substandard products of doing over again
Processing method, solar battery sheet of doing over again is carried out successively ultrasonic wave cleaning, washing for the first time, the cleaning of hot hydrochloric acid, second
Silk-screen printing is washed, dries and re-starts, it solves the solar battery sheet after existing printing and can not carried out effectively
Do over again processing and the problem of cause the wasting of resources, cost increase.But its do not relate to cell piece cleaning equipment, also without
Method realizes the cleaning of automation, and low with cleaning efficiency, effect is poor, is unfavorable for the production needs of industrialization.
For another example notification number is disclosed after a kind of crystal silicon solar cell sheet printing for CN100505334B patent of invention
Substandard products reworking method, including three steps：With HCL cleaning fluids, the aluminium paste at the cell piece back side is removed；Cell piece is removed with isopropanol
The silver paste in positive and negative two face；Depth cleaning is carried out to the cell piece for removing slurry substantially with depth cleaning fluid, thoroughly cleaning is fallen
Small impurity.By the processing of this method, the conversion efficiency of cell piece can reach the level of normal battery piece, and outward appearance
Also it is as good as with normal battery piece, has reached the purpose for cleaning of doing over again.The disqualification rate of cell piece silk-screen is by 2% or so original drop
It is low to 0.2% or so, so as to improve the qualification rate and yield rate of silicon solar cell.But it is also without reference to cell piece
The equipment of cleaning, can not also realize the cleaning of automation, low with cleaning efficiency, effect is poor, be unfavorable for the production of industrialization and need
Will.
