Description
Technical field
The invention belongs to solar battery sheet serigraphy field, relate to particularly a kind of mould that reduces solar battery sheet printing process rework rate.
Background technology
In manufacture of solar cells process, to print for its last production process, outward appearance and the performance of printing stage to cell piece plays very large effect, if press quality is poor, its conversion efficiency will reduce greatly.There is the sale of must demoting of the cell piece of defect in outward appearance, price is far below the price of normal product.Therefore, improve the yields of printing stage, can play very important effect for the production cost of solar battery sheet.
At printing stage, printed pattern skew is inevitable phenomenon, the each power-off of printing machine start shooting, answer a pager's call, change half tone, restart rear all need again to debug print inclined to one side.Generally, actuator debugs at 3～5 at every turn, and roustabout, greatly about 10 left and right, if all can produce bad after the normal printing-sintering of the silicon chip printing in debug process, has a strong impact on product yield, and then increased production cost.In order to reduce printing fraction defective, generally printing skew figure can be wiped out, then again printing to improve yields.But after the silicon chip printing-sintering of doing over again through wiping, electrical property can be greatly affected.Therefore,, in order to improve product yield, a kind of solution must need be looked for: under the prerequisite that ensures press quality, reduce printing rework rate.
Summary of the invention
Goal of the invention: for solving the technical problem existing in prior art, the present invention proposes a kind of mould that reduces solar battery sheet printing process rework rate, can improve solar battery sheet printing yield effectively, reduces costs.
Technology contents: for realizing above-mentioned technical purpose, the present invention proposes a kind of mould that reduces solar battery sheet printing process rework rate, comprise die ontology, the silicon chip using in the size of described die ontology and printing process measure-alike, there is one deck baking vanish layer on the surface of die ontology, above baking vanish layer, be printed with patterned layer, the pattern of described patterned layer is identical with the half tone pattern of the printing machine platform in production technology, pattern can need to design according to the technique of our company, the outside of the pattern of patterned layer and the distance of silicon chip edge are provided with graduated scale, distance between outside and the silicon chip edge of the pattern of patterned layer is provided with graduated scale.
Wherein, the color of described baking vanish layer is light color, and as light blue or light grey, but described light color can not be white, because white can be reflective under camera, grab and be afraid of less than border in flash of light process.The color of described pattern is dark, as black or darkviolet.
The length of described mould × wide is (156 ± 0.5) mm × (156 ± 0.5) mm, and thickness is 150～350 μ m.
Described mould is the mould of being made up of any one material in steel plate, PC/PMMA composite plate, PP plate, PE plate and acrylic board.It is strong that the material require of mould possesses hardness, the feature withstand voltage, impact resistance better, does not react or mix with organic solvent.Preferably, the material for being made up of steel plate of described mould, because PC/PMMA composite plate, PP plate, PE plate or acrylic board etc. all belong to macromolecular material, is difficult for degraded, so consider the problem of environmental protection aspect, suggestion selects steel plate to make in enormous quantities use.
Mould (silicon chip substitute) must possess following characteristics: (1) is difficult for broken, can be repeatedly used, and with low cost; (2) not flexible, there will not be folding line as stock, damage half tone; (3) in printing process, do not affect printing machine camera and catch image; (4) mould does not react with organic matters such as alcohol, alcohols, aromatic hydrocarbon; (5) repeatedly wiping there will not be to fall slag, fades or is out of shape, and can not pollute half tone surface and slurry.
Beneficial effect: the present invention can reduce bad that causes in debugging printing migration process effectively, while is because of the harder difficult fragmentation of material (as steel plate) of mould, also can effectively reduce the fragment causing in debug process, under the prerequisite that ensures press quality, reduce printing rework rate, and then reduce production costs.
Brief description of the drawings
Fig. 1 is the schematic diagram of screen printing process;
Fig. 2 is the schematic diagram of mould of the present invention.
Detailed description of the invention
As shown in Figure 1, the formation of serigraphy comprises 5 large factors, as shown in Figure 1, comprises silk screen, scraper, slurry, workbench and substrate, utilizes the saturating slurry of silk screen picture and text part mesh, and non-graphic part not thoroughly the general principle of slurry print.When printing, pour slurry in silk screen one end, apply certain pressure at the slurry position of silk screen with scraper, move towards the silk screen other end simultaneously.Slurry is pressurized on substrate from the mesh of visuals by scraper plate in movement.Printing process middle scraper is line with screen printing forme and stock all the time and contacts, contact wire moves with scraper and mobile (as shown in Fig. 1 direction of arrow), and silk screen other parts and stock are disengaged position, ensure printed dimensions precision and avoided the stock of making dirty.After scraper plate is scraped whole printing zone, lifted, silk screen also departs from substrate simultaneously, and by returning blade, slurry is scraped back to initial position, and workbench turns back to material loading position, completes a printing process.
In order to reduce the impact on silicon chip performance in printing process, the utility model proposes a kind of mould that reduces solar battery sheet printing process rework rate, for changing half tone at printing machine, replacing silicon chip printing while answering a pager's call.This mould comprises die ontology 1, it is made up of steel plate, the substrate (silicon chip) using in the size of die ontology 1 and printing process measure-alike, there is the baking vanish layer of one deck grey (light colour) on the surface of die ontology 1, above baking vanish layer, be printed with the patterned layer of black (dark colour), the pattern of described patterned layer is identical with the half tone pattern of the printing machine platform in production technology, and the distance between outside and the silicon chip edge of the pattern of patterned layer is provided with graduated scale 2.
In actual applications, taking back electrode layout as example, design configuration as shown in Figure 2: Grounding of Medium is grey, and grid line color is black.Add scale size (printing X, Y direction) at grid line apart from the adjacent two edges of stock, using this as printing side-play amount with reference to judgement.
Pattern shown in Fig. 2 is only for reference, in practical application, can on steel plate, print corresponding figure according to the technique of moving on production line.If production-line technique is improved rear half tone drawing and is changed, can on steel plate, again paint, recycling.
Because steel plate material is difficult for fragmentation, can be repeatedly used, with low cost, not flexible, there will not be folding line as stock, damage half tone; In printing process, do not affect printing machine camera by spraying paint yet and catch image; Mould does not react with organic matters such as alcohol, alcohols, aromatic hydrocarbon; Repeatedly wiping there will not be to fall slag, fades or is out of shape, and can not pollute half tone surface and slurry, therefore, the utility model can reduce bad that in debugging printing migration process, causes effectively, can effectively reduce the fragment causing in debug process, under the prerequisite that ensures press quality, reduce printing rework rate, and then reduce production costs.
