Chinese patent CN101969082A discloses a kind of solaode manufacture combined by printing of screen cloth twice with cutting
Technique, for manufacturing a kind of solaode for printing electrode twice, includes cutting technique and typography twice, cutting work
Skill is：In the gate electrode line region cutting of silicon chip surface, gate electrode line region is made to form erosion groove；Typography is twice：A,
One-step print electrode：The electrode slurry of printing is inserted erosion groove and is dried, in erosion groove, form ground floor electrode；B, second
Secondary print electrode：Print electrode in ground floor electrode outer surface, make silicon chip surface gate electrode line region form second layer electrode.
The silk screen for constituting conventional composite type mask plate is Weaving type metal gauze or polyester webs etc., and such silk screen is due to braiding
The characteristic of type longitude and latitude node can cause the lower slurry effect of final molding mask plate, such as：Lower slurry is uneven；Making in actual mask plate
During, generally require first to extrude silk screen, so as to reduce this effect of Weaving type silk screen as far as possible.But both so operate
And the ill effect that longitude and latitude node brings cannot be avoided completely.
The present invention is primarily directed to this problem and proposes a kind of silk screen, preferably solves problems described above.
Content of the invention
One of the technical problem to be solved is in existing accurate printing technology, as silk screen used has braiding
Type longitude and latitude node, causes patterned mask plate to print uneven problem, and the present invention provides a kind of new silk screen, and the screen cloth does not have
Longitude and latitude node, smooth surface are high have the advantages that printing uniformity.
The two of the technical problem to be solved are to provide a kind of mask plate that makes using above-mentioned silk screen, the mask
Plate has the uniform advantage of printing.
For solving one of above-mentioned technical problem, the technical solution used in the present invention is as follows：A kind of silk screen, zone line are net
Lattice structure, outer rim are the lateral opening structure for fixing the silk screen, and there is in the network figure being made up of lines 1a arrays；
Figure main body is staggeredly made up of two groups of grid lines 2b1 and grid lines 2b2；Lines 1a is made up of one group of parallel bridging line 2a1, institute
The angle α for stating the 2a body regions that bridging line 2a1 is constituted with which is 0 ~ 180 °.
In above-mentioned technical proposal, preferred technical scheme is to constitute the line footpath size of grid lines 2b1,2b2 of silk screen main body
Line footpath sizes r2 of the r1 more than or equal to the bridging line 2a1 for constituting bargraphs region.10≤r2 of the line footpath size≤r1≤
80.The angle α of the least one set grid lines and bridging line that constitute silk screen main body is 10 ~ 170 °.Constitute a networking of silk screen main body
Ruling 3b1 is coherent structure with the bridging line 3a1 for constituting 3a regions；The bridging line 4a1 for constituting two adjacent 4a regions is mirrored into
Relation.Silk screen surface-coated overlays one layer of photopolymer；Photopolymer is distributed in the agent structure of silk screen and strip
Subregion in structure 3a, region that is uncoated or overlaying photopolymer form Openworks shape.It is covered with the structure of photopolymer
The width dimensions R1 of the width dimensions R2 of void region≤original list structure 3a.In the x directions parallel to void region main body
On, the adjacent head end of the previous bridging lines of two bridging line 6a1 is in same position on x directions with the tail end of next bridging line.Silk
Netting twine line footpath size r1, r2, opening size R1, R1 of graphics field ', R2, R2 ', 25um≤R1（R1’）≤300um.
For solving the two of above-mentioned technical problem, the technical solution used in the present invention is as follows：A kind of prepared using above-mentioned silk screen
Mask plate, it is characterised in that the opening size of the mask plate graphics field is not more than corresponding figure in the Metal screen cloth
The size of web lines absent region.
In above-mentioned technical proposal, preferred technical scheme is that the structure of silk screen is to be integrally formed by electroforming process, surface
Smooth, without Weaving type longitude and latitude node；Its material is pure nickel material or nickel-bass alloy material.
The silk screen that the present invention is provided, which has advantages below：1st, the silk screen is obtained by electroforming process, and which has table
The smooth characteristic without establishment type longitude and latitude node in face, is starched in printing at present by its electrode of solar battery Printing screen for making
Uniformly；2nd, the silk screen in the corresponding region of thin grid line of corresponding electrode of solar battery Printing screen without thin grid line place side
Grid lines upwards, reduces inhibition of the silk screen to printing slurry.
The metal gauze of non-woven, silk screen smooth surface, the mask plate which is made will not be by during cleaning is wiped
The uneven damage for causing mask plate in surface.Silk screen can design different percent openings, silk screen line footpath chi as needed
Very little and silk screen wire shaped, is ensureing that silk screen can also ensure the life-span of silk screen while having preferably lower slurry effect.
Based on above advantage, further obtained electrode of solar battery Printing screen can print " height to the silk screen
Wide ratio " preferably silicon solar battery electrode grid line structure, which is conducive to collection and transmission of the solar battery sheet to electric current, from
And it has been correspondingly improved the transformation efficiency of solar battery sheet.
