Description
Technical field
The present invention relates to the production fields of solar battery sheet, and in particular to a kind of etching slot cover plate condensate liquid drying dress
It sets.
Background technique
With the continuous improvement of battery chip technology, higher and higher, the increasing of reflectivity is required to the backside reflection rate after etching
Adding the usage amount of nitric acid and hydrofluoric acid just will increase, and the volatile quantity of etching groove becomes more also with the increase of liquor strength in turn,
The condensate liquid accumulated on cover board also will increase very much, can drip when forming big condensate liquid on the cover board with the volatilization accumulation of medical fluid
Cell piece front is fallen in, destroys positive PN junction, forming blackspot stain influences the A grade product rate of cell piece, dirty impurity on cover board
Also groove body can be polluted in groove body as condensing droplet is fallen in.
Summary of the invention
In view of this, present invention aim to address above-mentioned the deficiencies in the prior art, a kind of reduction acid mist is provided in cover board
On condensation rate etching slot cover plate condensate liquid drying unit.
The present invention solves technical solution used by above-mentioned the deficiencies in the prior art: a kind of etching slot cover plate condensate liquid baking
Equipment for drying which is provided with air-heater, exhaust duct and exhaust pipe, which further includes one
Double-layer cover plate which is provided with a cover with liner, and the heat which generates is sent to the cover with liner via the exhaust duct,
Heat the double-layer cover plate.
Particularly, which includes the first cover board and the second cover board being made of several cover plate units, cover board folder
Layer is set among first cover board and second cover board.
Particularly, female connector is caught in via sub- connector between several cover plate units to fix.
Particularly, air inlet and outlet, gas vent and handle are equipped on first cover board and second cover board.
Particularly, the exhaust gas of the generation after heating the double-layer cover plate is discharged into peripheral processing system via the exhaust pipe.
Particularly, which is made of polypropylene material.
Particularly, which is made of polypropylene material.
Particularly, which is made of pvc material.
Compared to the prior art, etching slot cover plate condensate liquid drying unit of the invention is carved using air-heater as heating
The heat source of erosion tank cover plate is sent in the cover with liner of double-layer cover plate, heats cover board, can be effective when acid mist drips on the cover board
The condensation rate of acid mist on the cover board is reduced, cover board uses double layer design, and it is structurally reasonable and easy to operate, it is carried using drying tank
Air-heater heating, easy to implement without increasing new heating device, testing result comparison is obvious, improves the yields of cell piece.
