Description
Technical field:
The present invention relates to a kind of applicator roll assembly for roll printing backlight glass and application process thereof, it belongs to solar photovoltaic assembly technical field.
Background technology:
The two glass assembly of solar energy, because have following advantages, is applied more and more wider in recent years:
1) permeability rate of glass is almost nil, does not need to consider that steam enters the problem that assembly brings out EVA adhesive film hydrolysis.The backboard of conventional crystal silicon solar assembly has certain permeability rate, and the steam through backboard makes EVA resin inferior divide very soon and parses acetic acid, and causes component internal generation electrochemical corrosion, adds the probability occurring that PID decay and snail line occur.It is particularly useful for the photovoltaic plant in seashore, waterside and higher levels of humidity area;
2) glass is inorganic matter silicon dioxide, belongs to material of the same race with the sand be seen everywhere, and weatherability, corrosion resistance exceed the known plastics of any one; Ultraviolet, oxygen and moisture cause backboard to be degraded gradually, and efflorescence and self fracture occur on surface; Use the glass weather-proof problem solving assembly of then putting things right once and for all, also finish which more weather-proof controversial issue of PVF and PVDF, more need not carry weatherability, the PET backboard of water preventing ability difference, application type backboard and other low side backboard; This feature makes two glass assembly be applicable to the photovoltaic plant in more acid rain or the large area of salt fog;
3) resistance to wear of glass is very good, also solves assembly resistance to windsand problem in the wild.The place of large dust storm, the resistance to wear of two glass assembly is with the obvious advantage;
4) two glass assembly does not need aluminium frame, unless had outside the situation of a large amount of dewdrop at glass surface; The electric field not having aluminium frame to make to cause PID to occur cannot be set up, and it greatly reduces the possibility that PID decay occurs;
5) insulating properties of glass is better than backboard, and it makes two glass assembly can meet higher system voltage, the high potential assembly of such as 1500v, can increase singly to go here and there component count, saves system and the cost of investment in whole power station;
6) fire-protection rating of two glass assembly is upgraded to A level by the C level of common crystal silicon component, makes it be more suitable for needing to avoid for residential building, chemical plant etc. the area of disaster hidden-trouble.
Although two glass assembly has advantages much more so, never use on a large scale in photovoltaic plant, an important reason is exactly that it uses front and back to be all transparent EVA adhesive film, because light leak causes power to have greater loss; Owing to not having the light leak between the backboard of white reflection cell piece to return in assembly, assembly has more than at least 2% power loss.
For solving the power loss that back-panel glass light leak causes, development in recent years two kinds of method head it offs.
One is on back-panel glass surface, adopts silk-screen mode, and at cell piece gap relative position, printing white ink, baking and curing sinters.Its advantage saves ink, and shortcoming is that silk-screen speed is slow, and be unfavorable for that streamline is produced fast, half tone is fragile, cleaning trouble.
Two is print white high temperature ink at the full plate of back-panel glass surface rolling method, and drying is solidified, and enters annealing furnace sinter molding.Its advantage is convenient to fast pipeline produce, and technique is simple, and shortcoming is that ink consumption amount is large, and material cost is high.
Summary of the invention:
The invention provides one and both saved ink, be convenient to again the applicator roll assembly for roll printing backlight glass and the application process thereof of fast pipeline production.
The present invention adopts following technical scheme: a kind of applicator roll assembly for roll printing backlight glass, comprise roller and scraper, roller comprises roll shaft and is sheathed on the sleeve on roll shaft, described sleeve is cylindric, sleeve outer surface axially and in radial direction is provided with some orthogonal wire casings, wire casing is spill, and described scraper to be positioned at above sleeve outer surface and to be close to sleeve outer surface.
Further, described wire casing width is 3-40mm, and the degree of depth is 0.2-2mm.
Further, the material of described roller is rubber or silica gel.
The present invention also adopts following technical scheme: a kind of application process of the applicator roll assembly for roll printing backlight glass, it comprises the steps:
Step one: applicator roll assembly is provided, axially mutually perpendicular wire casing is carved with radial direction at roller outer surface, the distributing position of wire casing launches rear corresponding with back-panel glass print grid position, and glass printing lines location and two glass photovoltaic module cell piece gap coincide, and wider than cell piece gap;
Step 2: be close to roller outer surface a scraper is set above roller outer surface;
Step 3: arrange row's inking up device above roller, ink evenly flow to roller surface;
Step 4: when roller rotates, roller surface does not need printing position ink to scrape totally by scraper, and leaves ink in wire casing;
Step 5: roller linear velocity is synchronous with glass pace, contacts with glass surface when roller rotates, by ink print in wire casing to glass surface;
Step 6: the complete glass of roll marks directly enters drying tunnel and dries, and enters annealing furnace tempering subsequently, and ink is sintered, form finished product.
Further, described printing-ink is white high temperature ink.
Further, described back-panel glass is 2-3.2mm float glass.
The present invention has following beneficial effect:
(1) at backboard photovoltaic glass surface, adopt roller coating technology, be coated with the latticed low-melting glass glaze of last layer, wherein add white inorganic pigment and high reverse--bias material, drying, enter annealing furnace, through high temperature sintering, form one deck white inorganic oxide coating at glass surface, this Coating Durability is good, peel strength is high, and reflectivity is high, reduces component package power loss;
(2) this roller coating technology is easy to streamline setting, and roll marks speed is fast, and production efficiency is high;
(3) this roller coating technology print grid striped position, justifying of comparing face roller coat, saves ink, significantly reduces production cost.
